The present disclosure relates to a laundry treatment apparatus, and more particularly to a laundry treatment apparatus capable of supplying hot air or moisture to laundry to perform deodorizing, drying and removal of wrinkles of the laundry.
Generally, a laundry treatment apparatus conceptually includes a washing machine configured to wet laundry with water and then to remove foreign matter from the wet laundry through chemical action of detergent and physical action such as rotation of a drum, and a dryer configured to dry the wet laundry using hot air and steam.
Recently, a laundry manager, which is designed to deodorize dried laundry in the state of not being wet with water or to remove moisture or wrinkles from the laundry, has been developed. This kind of laundry manager is able to perform a refresh procedure of deodorizing, drying or sterilizing laundry by supplying steam or hot air in the state in which the laundry is supported.
In a typical laundry treatment apparatus, it is possible to use a heat pump or a heater in order to dry laundry. A laundry treatment apparatus, which uses a heat pump, is designed to dehumidify moisturized air using an evaporator and a condenser and then to heat the air, thereby supplying high temperature dry air to laundry. Because a heat pump is able to create high temperature heat using a smaller amount of energy than a heater, it is excellent in energy efficiency's point of view.
Referring to Korean unexamined patent publication No. 10-2016-0075157, a conventional laundry treatment apparatus 1 includes a casing 10 defining the appearance of the laundry treatment apparatus 1, and a door 20 which is rotatably provided at the casing 10 to open and close the opening formed in the front surface of the casing 10.
A treatment compartment 11 is formed in the casing 10 in order to treat laundry, and the lower portion of the treatment compartment 11 is provided with a machine compartment 12 in which devices configured to supply hot air or steam which are used to treat laundry are mounted.
Furthermore, the treatment compartment 11 may be provided with a hanger 30 by which laundry is supported. Laundry may be coupled to the hanger 30 in the state of being hung on a clothes hanger. Accordingly, the laundry may be treated in the treatment compartment 11 in a spread state.
A water supply container 41, which stores therein water for creation of steam which is used in treatment of laundry, may be mounted on the front surface of the machine compartment 12. Furthermore, a water discharge container 42, which stores therein condensed water which is generated during treatment of laundry, may be mounted on the front surface of the machine compartment 12.
Furthermore, the conventional laundry treatment apparatus 1 may include a treatment compartment lower panel 50 which forms the lower surface of the treatment compartment 11. Through holes, which are in communication with the machine compartment 12 and the treatment compartment 11, may be formed through the treatment compartment lower panel 50.
The through holes may include a steam discharge hole 52 configured to supply steam created in the machine compartment 12 to the treatment compartment 11. Furthermore, the through holes may include a blowing hole 51 configured to move the air in the treatment compartment 11 to the machine compartment 12 or to move the air in the machine compartment 12 to the treatment compartment 11.
Referring to
The inside of the machine compartment 12 may be provided with an air supply duct 65 into which the air in the treatment compartment 11 is introduced. The air supply duct 65 may be connected to a blower 64. The blower 64 may include a fan motor configured to generate an airflow. Furthermore, the blower 64 may be in communication with the air supply duct 65 so as to generate an airflow.
A heat pump module 61, which is configured to exchange heat with air, may be provided downstream of the blower 64. The heat pump module 61 may include an evaporator and a condenser. Consequently, the air, which is introduced into the heat pump module 61 by the blower 64, may be cooled in the evaporator and then be heated in the condenser.
A support 67 configured to support components may be mounted on the base 70. The support 67 may include a plurality of supports in order to more firmly support the components.
A controller 62 configured to control the components of the laundry treatment apparatus 1 may be mounted on the support 67. Furthermore, the support 6767 may support a steam generation module 63 configured to create steam to be supplied to the treatment compartment 11.
In other words, the steam generation module 63 and the controller 62 may be supported by the support 67 which is separately mounted on the base 70.
Furthermore, a compressor 66 configured to compress refrigerant to be supplied to the heat pump module 61 may be mounted on the machine compartment 12. The compressor 66 may be connected to the heat pump module 61 so as to supply the compressed refrigerant to the heat pump module 61.
In summary, the air supply duct 65, the blower 64, and the heat pump module 61 may be connected to one another in that order so as to a flow channel along which the air in the treatment compartment 11 is circulated. Other components may be mounted outside the flow channel along which the air is circulated. The other components may be mounted in the machine compartment 12 via the support 67 separately mounted on the base 70, rather than being directly coupled to the base 70.
In other words, the conventional laundry treatment apparatus 1 may be constructed such that various components configured to treat laundry as separate components are disposed in the machine compartment 12. Specifically, the various components are mounted on the base 70, which forms the bottom surface of the machine compartment 12, so as to form a flow channel along which air is circulated. In addition, in order to mount the controller 62 and the steam generation module 63, the additional support 67 must be mounted on the base 70.
Accordingly, because it is difficult to directly mount the components on the base 70, an assembly process become complicated. Furthermore, because the components are separate from each other, there is a problem in that structural stability is deteriorated.
Furthermore, because the compressor 66 applied to the conventional laundry treatment apparatus 1 is shaped such that the width thereof is greater than the height thereof, the compressor 66 occupies a large area on the base.
In addition, the conventional laundry treatment apparatus 1 cannot ensure a space configured to separately store condensed water, in the heat pump module 61.
Furthermore, because the conventional laundry treatment apparatus 1 is constructed such that the blower 64 is disposed in the front of the machine compartment 12, there is a problem in which efficiency of airflow is deteriorated.
In addition, because the conventional laundry treatment apparatus 1 is constructed such that the flow channel along which air is circulated is constituted by a plurality of components, such as the air supply duct 65, the blower 64 and the heat pump module 61, there is the possibility of air leakage being generated.
Furthermore, because the conventional laundry treatment apparatus 1 has the possibility of flow loss being generated while the air introduced from the treatment compartment 1 moves downwards and then moves upwards through the blower 64.
In addition, the conventional laundry treatment apparatus 1 is constructed such that the base 70 is made of a thin structure such as steel plate, there is a limit to reduction in vibration caused by the compressor 66.
Furthermore, the conventional laundry treatment apparatus 1 is constructed such that the controller 62 is supported by the additional support 67 coupled to the base 70. Accordingly, the assembly process thereof becomes complicated, and there is a limit to ensuring structural stability in assembly.
In other words, because the conventional treatment apparatus 1 is constructed such that the components constituting the machine compartment are individualized, there are problems in which the number of assembly processes increases and the possibility of leakage of air or water being generated.

Although the circulation duct 320 may be constructed so as to be coupled to the base 310, the circulation duct 320 may also be constructed integrally with the base 310. For example, the base 310 and the circulation duct 320 may be produced through injection molding.
The machine compartment 300 may include a base cover 360 configured to allow the circulation duct 320 and the introduction hole 231 to communicate with each other.
The base cover 360 may be coupled to the upper portion of the circulation duct 320 so as to guide the air drawn in through the introduction hole 231 to the inside of the circulation duct 320.
The base cover 360 may block the upper surface of the circulation duct 320 to prevent the air inside the circulation duct 320 from being discharged to the outside. The lower portion of the base cover 360 and the upper surface of the circulation duct 320 may define one surface of the flow channel in the circulation duct 320.
The base cover 360 may include an introduction portion 362 which connects the introduction hole 231 to the circulation duct 320. The introduction portion 362 may be constructed to have a duct shape so as to serve as an intake duct configured to transfer the air in the inner case 200 to the circulation duct 320.
The machine compartment 300 may include the steam supply 800, which is connected to the water supply container 301 so as to receive water from the water supply container 301 to create steam and to supply the steam the inner case 200. The steam supply 800 may be disposed and mounted on the upper portion of the base cover 360.
The steam supply 800 may be disposed behind the introduction portion 362.
The machine compartment 300 may include a fan installation portion 350 configured to allow the circulation duct 320 and the inner case 200 to communicate with each other.

The fan installation portion 350 may include a discharge duct 352 configured to allow the circulation duct 320 and the discharge hole 232 to communicate with each other.
The discharge duct 352 may extend toward the discharge hole 232 while maintaining a cross-sectional area at the fan housing 351 corresponding to the cross-sectional area of the discharge hole 232.
As a result, the air in the inner case 200 may be introduced through the base cover 360, may pass through the circulation duct 320, and may be supplied to the inside of the inner case 200 through the fan installation portion 350.
The base 310 may include a compressor installation portion 312 on which the compressor 342 configured to supply refrigerant to the heat exchanger 341 and 343 is mounted. The compressor installation portion 312 may be disposed outside the circulation duct 320.

Because the controller 700 is inserted into the base 310 and is supported thereby, it is possible to reduce vibration or impact applied to the controller 700. Furthermore, because the controller 700 is disposed close to all the electronic components, it is possible to minimize occurrence of errors in control such as noise.
The steam supply 800 may be disposed at the upper portion of the circulation duct 320, and the controller 700 may be disposed at the lower portion of the circulation duct 320. Consequently, the circulation duct 320 may be linearly disposed between the steam supply 800 and the controller 700 so as to take the shape of a linear duct. As a result, it is possible to minimize the resistance to air flowing in the circulation duct 320.
The circulation duct 320, the external air duct 370, the steam supply 800, the controller 700, and the heat supply 340 may be provided at the base 310 in a modular fashion.
Consequently, the base 310 may be forwardly taken out of and backwardly put into the machine compartment 300, thereby facilitating installation and maintenance of the laundry treatment apparatus.

The air discharge portion 323 may extend backwards from the duct body 321 in the shape of a pipe. The air discharge portion 323 may have a diameter smaller than the width of the duct body 321.
The air discharge portion 323 may be connected to the fan housing 351. The air discharged from the air discharge portion 323 may be guided into the inner case 200 through the fan housing 351.
The circulation duct 320 may include an external air intake portion 322, which is formed through the front surface of the duct body 321.
The external air intake portion 322 may be constructed so as to communicate with the external air duct 370. The external air duct 370 may be mounted on the front side of the external air intake portion 322 and be supported thereby.
The external air intake portion 322 may have a height greater than the width thereof. In other words, the external air intake portion 322 may extend in the width direction of the duct body 321. When the external air intake portion 322 is structured as described above, external air may be more efficiently introduced into the duct body 321.
The circulation duct 320 may be provided with an external air damper 373 configured to open and close the external air intake portion 322. Opening and closing of the external air damper 373 may allow and block introduction of external air into the circulation duct 320.

The compressor installation portion 312 may include a protrusion capable of supporting the compressor 342. The compressor installation portion 312 may be disposed at the rear side of the base 310. The compressor installation portion 312 may be disposed such that at least a portion thereof overlaps the air discharge portion 323 in the width direction.
The compressor installation portion 312 may be provided with a shock absorber configured to reduce vibration transmitted from the compressor 342. The shock absorber may be fixed to the protrusion.
The base 310 may include the controller installation portion 313 on which the controller 700 is mounted. The controller installation portion 313 may be formed between the base bottom 311 and the circulation duct 320. The controller installation portion 313 may be formed between the base bottom 311 and the bottom surface of the circulation duct 320. The controller installation portion 313 may be disposed below the circulation duct 320, and may be constructed in the shape of a duct which is open at one of the front and rear sides thereof.
The structure of the controller installation portion 313 will be described later.
The circulation duct 320 may define a flow channel which extends upwards from the base bottom and through which air flows. The circulation duct 320 may include the heat exchanger installation portion 3212 which has a space in which the evaporator 341 and the condenser 343 are mounted. The heat exchanger installation portion 3212 may be provided in the duct body 321.
The duct body 321 may be open at the upper surface thereof. The evaporator 341 and the condenser 343 may be introduced and mounted through the opening of the duct body 321.
The opening of the duct body 321 may be blocked by the base cover 360, and the base cover 360 and the duct body 321 may define the flow channel in the circulation duct 320.
The front surface of the duct body 321 may be disposed at a location which is spaced backwards apart from the front end of the base bottom 311.
Consequently, the base bottom 311 may ensure a support surface 3111 on which one or more of the water supply container 301, the water discharge container 302 and the external air duct 370 are mounted and supported.
The heat supply 340 may include the evaporator 341, which is provided in the circulation duct 320 and serves as the heat exchanger configured to cool and dehumidify the air introduced into the circulation duct 320, the condenser 343 serving as the heat exchanger configured to heat the air having passed through the condenser 341 to create hot air, the compressor 342, which is disposed outside the circulation duct 320 and which supplies refrigerant to the condenser 343 to exchange heat with the air, and an expansion valve 344 configured to expand and cool the refrigerant having passing through the condenser 343.
Because the duct body 32 is formed integrally with the base 310, the heat exchanger installation portion 3212 may ensure a greater height, and the heights of the condenser 343 and the evaporator 341 may increase.
As a result, because the widths of the condenser 343 and the evaporator 341 in the forward/backward direction are reduced, it is possible to reduce the number of refrigerant pipes which extend through the condenser and the evaporator. Consequently, there is an effect of reducing flow loss of air which passes through the condenser and the evaporator.
The sum of the length of the evaporator 341 in the forward/backward direction and the length of the condenser 343 in the forward/backward direction may be less than the length of the heat exchanger installation portion 3212. Consequently, the length of the heat exchanger installation portion 3212 may be equal to or less than the half of the length of the duct body 321.
Accordingly, because the heat exchanger installation portion 3212 is sufficiently spaced apart from the external air intake portion, it is possible to ensure a sufficient space into which the air in the inner case 200 is introduced.
The inside of the duct body 321 may be provided with an installation partition wall 3211 configured to isolate the heat exchanger installation portion 3212 from the outside of the heat exchanger installation portion 3212. The installation partition wall 3211 may project from the lateral surface of the duct body 321 to support the front portion of the evaporator 341.
The duct body 321 may extend backwards while increasing in width based on the installation partition wall 3211.
As a result, the width of the heat exchanger installation portion 3212 may be greater than the half of the width of the base 310. Furthermore, the width of the circulation duct 320 may be greater than the half of the width of the base 310.
In addition, the width of the condenser 343 and the width of the evaporator 341 may be greater than half the entire width of the base 310.
When the condenser 343 and the evaporator 341 have the widths as described above, there is an effect of ensuring a sufficient heat exchanging capacity.
The fan installation portion 350 may be disposed so as to overlap the condenser 343 or the evaporator 341 in the forward/backward direction. Consequently, the air having passing through the evaporator 341 and the condenser 343 may be introduced into the fan housing 351 without passing through a bent flow channel portion. In other words, because the air, which is introduced into the circulation duct 320, moves to the fan housing 351 without passing through a bent flow channel portion, there is an effect of minimizing flow loss of the air.
The base 310 may be formed through injection molding such that the base bottom 311 is formed integrally with the circulation duct 320.
The metal mold, which is configured to mold the inner surface of the duct body 321, may be taken upwards out of the duct body 321 and then be removed. At this point, in order for the metal mold to be easily taken out of the duct body, the wall surface of the duct body 321 may be sloped by a predetermined angle relative to the direction in which the meal mold is removed.
The width of the lower surface 321a of the duct body 321 may be less than the width of the upper surface 321b of the duct body 321.
Specifically, the distance between the wall surfaces of the duct body 321 which are opposed to each other may increase as the distance from the base bottom 311 increases. The distance between the left lateral surface and the right lateral surface of the circulation flow channel may increase in the direction in which the metal mold is taken out, thereby making it easy to remove the metal mold.
The air discharge portion 323 may include an air extension pipe 3231, which extends such that the diameter or width thereof decreases in the backward direction of the duct body 321, and an air discharge pipe 3232, which extends from the air extension pipe 3231 to define a hollow 3233 having a constant diameter. Because the air extension pipe 3231 may serve as a nozzle, it is possible to increase the velocity of the air discharged from the air extension pipe 3231.
The inside diameter of the air discharge pipe 3232 may increase with increasing distance from the duct body 321. The change in inside diameter of the air discharge pipe 3232 may be caused by the direction in which the metal mold is removed. In other words, it is considered that the removal of the metal mold is facilitated by the change in the inside diameter.
The metal mold configured to mold the air discharge portion 323 may be removed as illustrated in the drawing. Specifically, the metal mold may first be taken forwards out of the inside of the air discharge portion 323 toward the inside of the circulation duct 320, and may then be removed toward the upper open surface of the circulation duct 320. In this way, the structure capable of facilitating removal of the metal mold may be formed.
The installation partition wall 3211 may be formed by projecting the inner wall of the duct body 321 inwards or by depressing the outer wall of the circulation duct inwards.
The heat exchanger installation portion 3212 may be formed between the heat exchanger installation partition wall 3211 and the air discharge portion 323.
The metal mold configured to mold the air discharge portion 323 may be taken forwards out of the .air discharge portion 323 and then be pulled upwards for removal thereof. There is a need to prevent interference with the heat exchanger installation wall when the metal mold configured to mold the air discharge portion 323 is taken forwards out of the inside of the air discharge portion 323. To this end, there is a need to control the design value of the air discharge portion 323.
Specifically, when the air discharge portion 323 is molded, a metal mold configured to mold the front part of the air discharge portion 323 based on a parting line 3233 and another metal mold configured to mold the rear part of the air discharge portion 323 based on the parting line 3233 may be separately prepared. Accordingly, the directions in which both the metal molds are removed may be different from each other. Specifically, the metal mold configured to mold the front part of the air discharge portion 323 based on a parting line 3233 may be pulled forwards, and the other metal mold configured to mold the rear part of the air discharge portion 323 based on the parting lien 3233 may be pulled backwards.
Specifically, in order to prevent interference with the heat exchanger installation partition wall while the metal mold is pulled forwards, a first distance 323a in the drawing may be less than a second distance 321c in the drawing. The first distance 323a may mean the distance between the parting line of the air discharge portion 323 and the front end of the air discharge portion 323. Furthermore, the first distance 323a may mean the distance between the parting line of the air discharge portion 323 and the rear opening of the circulation duct. Meanwhile, the second distance 323c may mean the distance between the front end of the air discharge portion 323 and the heat exchanger installation partition wall. Furthermore, the second distance 323c may mean the distance between the rear opening of the circulation duct and the heat exchanger installation partition wall 3211.
The controller 700 may be configured to control all of the components required to perform an arbitrary course including laundry refresh procedure by the laundry treatment apparatus according to the present disclosure. Although the controller 700 may be embodied as a PCB, the present disclosure is not limited thereto, and may be embodied as various devices for control.
The controller 700 may be inserted and seated in the controller installation portion 313.
The controller installation portion 313 may be disposed below the circulation duct 320.
The bottom surface of the circulation duct 320 may define the upper surface of the controller installation portion 313. The controller installation portion 313 may be disposed lower than the lower portion of the air discharge portion 323.
The controller installation portion 313 may be formed integrally with the base bottom 311. The controller installation portion 313 may be formed as a recess depressed in the circulation duct while the circulation duct 320 is molded to the base 310.
The controller 700 may be moved in a sliding manner on the controller installation portion 313 toward the front from the rear.
The controller 700 may be provided therein with a bracket 3131 configured to surround the controller. The bracket 3131 may be disposed on and beneath the controller, and may prevent foreign substances from entering the controller.
Furthermore, the bracket 313 may prevent damage to the circuit board in the controller 700 caused by heat or vibration transmitted to the controller 700. The bracket 313 may be made of a metal material. Because the bracket 3131 is made of a metal material, it is possible to prevent fire propagation to the controller 700.
As illustrated in the drawing, the controller 700 may be installed in a state of being sloped at a predetermined angle relative to the base bottom 311.
For example, the controller 700 may be disposed so as to be sloped toward the water reservoir 326. Accordingly, when water is discharged to the upper portion of the controller 700, the water may promptly escape from the controller 700. The bottom surface of the circulation duct 320 may be molded so as to be sloped toward the water reservoir 326.
The controller 700 may include a support 3132 which projects from a lateral surface thereof.
The controller installation portion 313 may include a rib 3134 which projects from two opposite lateral surfaces of the controller installation portion. The support 3132 of the controller may be disposed on the ribs 3134.
The support 3132 of the controller may support the total weight of the controller 700. When the support 3132 of the controller is disposed on the rib 3134 and is supported thereby, the controller 700 may be spaced apart from the base bottom 311 by a predetermined distance.
The rib 3134 may be formed integrally with the base 310. The rib 3134 may be injection-molded together with the base 310 and may be formed integrally with components, such as the base bottom 311 and the circulation duct 320, at the time of injection molding of the base 310.
The controller 700 may be provided on the front surface thereof with a controller-seating protrusion 3136. The controller installation portion 313 may be provided on the inner lateral surface thereof with a guide 3133 which projects backwards. The controller-seating protrusion 3136 may be coupled to the guide 3133. The controller-seating protrusion may be inserted into the guide. The controller may be positioned in place in such a way as to couple the controller-seating protrusion to the guide when the controller is inserted into the controller installation portion 313. The present disclosure is not limited to the above-described embodiment, and the male and female relationships in the coupling between the controller and the controller installation portion may be changed.
The two opposite lateral surfaces of the controller may be determined according to the manner in which the support is seated on the rib, as described above. By virtue of the coupling procedure, it is possible to couple the controller to the controller installation portion in place without an additional fastening element.
The base 310 may include the air discharge portion 323 configured to discharge treated air toward the fan housing 351.
The air discharge portion 323 may be configured to allow the inside of the circulation duct 320 or the duct body 321 to communicate with the fan housing 351. The air discharge portion 323 may be formed so as to have the shape of a bell mouth. Because the air discharge portion 323 is formed so as to have the shape of a bell mouth, it is possible to reduce flow loss of air and to improve efficiency of air circulation.
The air discharge pipe 3232 of the air discharge portion 323 may be formed so as to have the shape of a pipe. In the course of removing the metal mold, the metal mold disposed ahead of the parting line 3233 is taken forwards out of the air discharge portion whereas the metal mold disposed behind the parting line 3233 may be taken backwards out of the air discharge portion.
The fan installation portion 350 may be coupled to the air discharge pipe 3232 and be supported thereby. The fan housing 351 may include a coupling hole which is coupled to the outer circumferential surface of the air discharge pipe 3232 and in which the blower fan 353 is disposed.
The fan housing 351 may include the discharge duct 352 which extends to the discharge hole 232 from the outer circumferential surface or the outer side of the blower fan 353.
The fan housing 351 and the discharge duct 352 may together define therein a flow channel which accommodates the blower fan 353 and through which air flows.
The motor configured to rotate the blower fan 353 may be coupled to the outer side of the fan housing 351 and be supported thereby.
Referring to

The external air duct 370 may include an external air damper 373 configured to open and close the external air intake portion 322, and an external air driving portion 374 configured to perform control to rotate the external air damper 373 to selectively open the external air intake portion 322.
The external air damper 373 may be formed so as to have the shape of a plate capable of sealing the external air intake portion 322, and may be rotatably coupled to two opposite lateral surfaces of the external air intake portion 322.
The external air driving portion 374 may be embodied as an actuator which is coupled to the external air duct 370 or the circulation duct 320 to rotate the external air damper 373.
The external air duct 370 may include an extension duct 372 which extends forwards from the front side of the external air intake portion 322, and an air intake duct 371 which extends forwards from the extension duct 372 and into which external air is introduced.
The air intake duct 371 may extend from the lower portion of the extension duct 372 and on which the water supply container 301 and the water discharge container 302 are disposed. The water supply container 301 and the water discharge container 302 may be coupled to or seated on the air intake duct 371.
The air intake duct 371 may include an external air port 3711 which is provided at one end or the free end of the air intake duct 371 and through which external air is introduced, and a partition rib 3712 configured to partition the external air port 3711.
The external air port 3711 may be disposed lower than the door 400 so as not to be shielded by the door 400.
The partition rib 3712 may be configured to partition the inside of the external air port 3711 to prevent foreign matter or a user's body from entering the external air port 3711.
Referring to
At this time, when the blower fan 353 is activated, external air may be introduced into the circulation duct 320. When the compressor 342 is activated, the external air may be dehumidified while passing through the circulation duct 320 and may be supplied to the inside of the inner case 200.
The door 400 may further include a discharge port configured to discharge the air in the inner case 200 to the outside, and a discharge damper configured to selectively open and close the discharge port. The discharge port may be disposed so as to face the receiving space in the inner case 200.
Consequently, the dehumidified air may be discharged through the discharge port.
The external air may be filtered while passing through the shield filter 366, and may be discharged to the outside of the cabinet 100.
The steam supply 800 may be seated on the base cover 360 and be supported thereby.
The steam supply 800 may include a steam case 810, which is seated on the base cover 360 and stores therein water for creation of steam.
The circulation duct 320 may be disposed so as to overlap at least a portion of the steam supply 800 in the height direction of the cabinet 100.
The steam supply 800 may further include an installation bracket 870 capable of fixing the steam case 810 to the base cover 360.
The installation bracket 870 may be coupled to the base cover 360 so as to fix the steam case 810.
The installation bracket 870 may include a lower panel 871 configured to support the lower surface of the steam case 810 and a lateral panel 872 configured to support two opposite lateral surfaces of the steam case 810 at the lower panel 871.
The installation bracket 870 may further include at least one holding clip 873 which extends from the lateral panel 872 to prevent separation of the steam case 810.
The holding clip 873 may be detachably attached to the upper portion of the lateral surface of the steam case 810.
The compressor 342 may be disposed lower than the steam supply 800.
The installation bracket 870 may be configured to block transmission of heat generated by the compressor or heat generated by the refrigerant compressed in the compressor to the steam supply 800.
Furthermore, the installation bracket 870 may block transmission of fire to the steam supply 800 in the event of firing at the compressor 342.
The base cover 360 may include a fastening portion 3631 which is provided at a blocking body 363 and is detachably coupled to the steam supply 800. The fastening portion 3631 may have a structure configured to be detachably coupled to a projection projecting the lower portion of the steam case 810.
Consequently, even when a large amount of water is received in the steam case 810, the steam case 810 may be stably seated on the base cover 360.
Furthermore, because the steam case 810 is disposed higher than the circulation duct 320 such that the distance to the inner case 200 is reduced, it is possible to minimize condensation of steam created in the steam case 810 before the steam arrives the inner case 200.
Referring to
The circulation duct 320 may be constructed in such a fashion as to extend upwards from the base 310. In other words, the circulation duct 320 may be formed integrally with the base 310. The circulation duct 320 and the base 310 may be injection-molded by means of a metal mold. Specifically, the base 310 and the circulation duct 320 may be made of a material, such as synthetic resin or plastic, which is used in injection molding.
Both the circulation duct 320 and the base 310 may be defined as a base molding M. The base molding M may be made of various materials such as an injection-molding material. In the case in which an additional fastening portion is not present between the circulation duct 320 and the base 310, it is understood that the circulation duct 320 and the base 310 constitute the base molding M.
Because the base 310 and the circulation duct 320 are formed integrally, there is an effect of being capable of preventing air from leaking from the inside of the circulation duct 320. The circulation duct 320 and the base 310 may be connected to each other without using an additional connecting element. Accordingly, the circulation duct 320 may be more firmly supported by the base 310.
Because the base 310 and the circulation duct 320 are integrally formed, the height of the circulation duct 320 may increase. As the height of the circulation duct 320 increases, the height of the evaporator 341 and the condenser 343 may increase. As the height of the evaporator 341 and the condenser 343 increases, the width of the evaporator 341 and the condenser 343 in the forward/backward direction may decrease. Because the height increases, it is possible to provide a designed heat exchange effect even when the width decreases.
As the width of the evaporator 341 and the condenser 343 in the forward/backward direction decreases, flow loss of air passing through the evaporator 341 and the condenser 343 may be reduced. Consequently, the overall efficiency of the laundry treatment apparatus may be improved.
Furthermore, when the circulation duct 320 extends from the base 310 and is formed integrally with the base 310, it is unnecessary to provide a process of additionally assembling the circulation duct 320 with the base 310. Accordingly, there is an effect of improving productivity of the laundry treatment apparatus.
The circulation duct 320 may include the duct body 321 which extends toward the inner case 200 from the base 310. The duct body 321 may extend upwards from the base 310. The duct body 321 may define a flow channel in which the air in the laundry treatment space 220 is circulated.
Furthermore, the circulation duct 320 may include a duct opening 324 which is formed in the upper side of the duct body 321. In other words, the duct body 321 may form the lateral surface of the circulation duct 320. The duct body 321 may extend to define the lateral wall of the flow channel, and may include the duct opening 324 formed in the upper side thereof.
The evaporator 341 and the condenser 343 may be inserted through the duct opening 324. The evaporator 341 and the condenser 343 may be installed in the circulation duct 320 through the duct opening 324. The duct body 321 may be disposed so as to surround the evaporator 341 and the condenser 343.
When the duct body 321 is formed integrally with the base 310, the evaporator 341 and the condenser 343 may be more stably positioned in the duct body 321. Furthermore, it is also possible to prevent leakage of air passing through the evaporator 341 and the condenser 343.
The base cover 360 configured to shield at least a portion of the duct opening 324 may be coupled to the upper side of the duct body 321. The base cover 360 may define the flow channel for circulation of air, in conjunction with the duct body 321.
The base cover 360 may include the blocking body 363 configured to shield a portion of the duct opening 324, and an introduction body 361 which extends from the blocking body 363 and allows the circulation duct 320 to communicate with the laundry treatment space 220. The base cover 360 may include the introduction portion 362 which is formed in the introduction body 361 so as to allow air to pass therethrough.
The introduction body 361 may be disposed in front of the evaporator 341. In other words, the introduction body 361 may be positioned far away from the condenser 342 based on the evaporator 341.
The blocking body 363 may be disposed so as to overlap the evaporator 341 or the condenser 343 in the height direction. The introduction body 361 may extend forwards from the blocking body 363, and may be disposed so as to be spaced apart from the evaporator 341 or the condenser 343 in the forward/backward direction.
When the introduction body 361 and the evaporator 341 are disposed as described above, the air, which is introduced into the inside of the circulation duct 320 through the introduction body 361, may immediately flow in the internal space in the circulation duct 320 without coming into contact with the evaporator 341.
Specifically, the air, which is introduced into the circulation duct 320 through the introduction body 361, may be guided so as to sequentially pass through the internal space in the circulation duct 320, the evaporator 341, and the condenser 343. Consequently, there is an effect of being capable of improving heat exchange efficiency of air.
The base 310 may include the base bottom 311 which forms the support surface. The circulation duct 320 may extend upwards from the base bottom 311. The duct body 321 may extend upwards from the base bottom 311.
At least one of the water supply container 301 and the water discharge container 302 may be disposed on the base bottom 311.
The circulation duct 320 may include the installation partition wall 3211 which projects from the inner lateral wall of the duct body 321. The installation partition wall 3211 may be disposed in front of the evaporator 341 and the condenser 343.
The installation partition wall 3211 may concentrate the air in the duct body 321 toward the evaporator 341. In other words, the installation partition wall 3211 is capable of preventing the air from escaping through a lateral side of the evaporator 341. The installation partition wall 3211 is capable of improving heat exchange efficiency in the inside of the duct body 321.
The base 310 may include the compressor installation portion 312 which provides a space in which the compressor 342 is installed. The compressor installation portion 312 may be formed on the base bottom 311. The compressor installation portion may be formed integrally with the base 310. The compressor installation portion 312 may be formed so as to project from the base bottom 311.
In other words, the compressor installation portion 312 may also be simultaneously formed at the time of formation of the base 310 and the circulation duct 320. For example, the compressor installation portion 312 may be formed on the base 310 by means of a metal mold.
Referring to
Because the duct body 321 is spaced backwards apart from the front end of the base, a space may be provided at the front side of the base bottom 311. At least one of the external air duct 370, the water supply container 301, and the water discharge container 302 may be disposed in the space.
Because the duct body 321 is disposed so as to be spaced backwards apart from the front end of the base 310, there is an effect of being capable of utilizing the front space of the base 310 more efficiently.
The circulation duct 320 may further include the air discharge portion which extends from the duct body 321 and guides air to the outside of the circulation duct 320. The air discharge portion 323 may be connected to the rear wall of the duct body 321 and extend from the duct body 321. A width of the air discharge portion 323 may be less than the width of the duct body 321.
The circulation duct 320 may be disposed so as to overlap at least a portion of the compressor installation portion 312 in the forward/backward direction. Specifically, the circulation duct 320 may be disposed such that the right portion of the circulation duct 320 overlaps the left portion of the compressor installation portion 312 in the forward/backward direction. In other words, the circulation duct 320 may be disposed so as to overlap at least a portion of the compressor 342 in the forward/backward direction.
Furthermore, the circulation duct 320 may be disposed so as to overlap at least a portion of the compressor installation portion 312 in the width direction of the base 310. The air discharge portion 323 may be disposed so as to overlap the compressor installation portion 312 in the width direction.
Because a conventional laundry treatment apparatus is constructed such that the space on the base which is occupied by a compressor is relatively large, a component corresponding to a circulation duct was disposed above the compressor. In other words, it is difficult to arrange the circulation duct and the compressor to overlap each other in the width direction or in the forward/backward direction.
However, the laundry treatment apparatus according to an embodiment of the present disclosure is changed in size of the compressor thereof. Accordingly, it is possible to reduce the space on the base 310 which is occupied by the compressor 342. Consequently, the circulation duct 320 may be disposed so as to overlap the compressor 342 or the compressor installation portion 312 in the forward/backward direction. Furthermore, the circulation duct 320 may be disposed so as to overlap the compressor 342 or the compressor installation portion 312 in the width direction of the base 310.
As a result, there is an effect of allowing the components such as the compressor 342 to be more densely disposed on the base 310. In other words, there is an effect of being capable of increasing the laundry treatment space 220 by virtue of improvement in space availability.
Referring to
The base 310 may include the controller installation portion 313 which is formed at the lower portion of the circulation duct 320 to provide a space in which the controller 700 is installed. The circulation duct bottom surface 325 may form the upper surface of the controller installation portion 313. At least a portion of the controller installation portion 313 may be disposed at the lower portion of the circulation duct bottom surface 325.
A water reservoir lateral surface 3265, which forms the lateral surface of the water reservoir 326, may form a lateral surface of the controller 700. The controller installation portion 313 and the water reservoir 326 may be disposed so as to overlap each other in the width direction of the cabinet 100. Furthermore, the circulation duct 320 may be disposed so as to overlap the controller installation portion 313 in the height direction of the cabinet 100. Particularly, the circulation bottom surface 325 may be disposed so as to overlap the controller installation portion 313 in the height direction of the cabinet 100.
A metal mold, which is configured to form the inner lateral surface of the circulation duct, may be removed toward the duct opening 324. Accordingly, the width of the duct body may increase as the distance from the base 310 increases. When the width of the duct body 321 increases in an upward direction, it is easy to remove the metal mold.
Referring to
The duct body 321 may be sloped upwards in the outward direction of the duct body 321 in a direction in which the duct body 321 extends. In other words, the distance between the inner walls of the duct body 321 may increase in the upward direction. Particularly, the distance between two opposing inner walls of the duct body 321 may increase in the upward direction.
Referring to
The angle defined between the direction in which the metal mold is removed and the inner wall of the duct body 321 is denoted by “m1” and “m2”.
The left inner wall of the duct body 321 may define the first body angle m1 relative to the metal mold removal direction MR. The first body angle m1 may be an angle which is sloped in an outward direction of the duct body 321 as the distance from the circulation duct bottom surface 325 increases.
The right inner wall of the duct body 321 may define the second body angle m2 relative to the metal mold removal direction MR. The second body angle m2 may be an angle which is sloped in an outward direction of the duct body 321 as the distance from the circulation duct bottom surface 325 increases.
Specifically, the first body angle m1 and the second body angle m2 may be angles which are sloped in different directions. By virtue of the first body angle m1 and the second body angle m2, the metal mold configured to form the left inner wall and the right inner wall of the duct body 321 may be easily removed.
The right inner wall of the water reservoir 326 may be formed by the right inner wall of the duct body 321. Meanwhile, the left inner wall of the water reservoir 326 may be separately formed by a metal mold. The water reservoir lateral surface 3265, which forms the left inner wall of the water reservoir 326, may define a third body angle m3 relative to the metal mold removal direction MR. The third body angle m3 may be an angle in which the water reservoir lateral surface 3265 is sloped in the outward direction of the water reservoir 326 as the distance from the base 310 increases.
In other words, the third body angle m3 may be sloped in the same direction as the first body angle m1. The third body angle m3 may be sloped in a direction different from the second body angle m2. When the third body angle m3 and the second body angle m2 are sloped in different directions, the metal mold, which forms the water reservoir 326, may be more easily removed.
As described above, the installation partition wall 3211 may project from the inner wall of the duct body 321. The installation partition wall 3211 may be formed in a manner such that the outer wall of the duct body 321 is depressed in the inward direction of the duct body 321.
Here, the metal mold, which forms the installation partition wall 3211, may be inserted into the duct body 321 from the outside of the duct body 321, and may then be taken outwards out of the duct body 321 upon removal of the metal mold.
In other words, the metal mold, which is configured to form the inner surface of the installation partition wall 3211, may be removed upwards, and the metal mold, which is configured to form the outer wall of the installation partition wall 3211, may be removed in the width direction of the base 310.
Here, in order to allow the metal mold, which is configured to form the installation partition wall, to be easily removed, the installation partition wall 3211 may define a predetermined angle relative to the metal mold removal direction.
The metal mold, which forms the inner surface of the installation partition wall 3211, may be removed in the height direction of the cabinet 100. Accordingly, the inner surface of the installation partition wall may define a fourth body angle m4 relative to the metal mold removal direction MR. The fourth body angle m4 may be an angle which is sloped upwards relative to the metal mold removal direction MR toward the duct body 321 at which the installation partition wall 3211 is formed.
In other words, the installation partition wall 3211 may be constructed such that the cross-sectional area thereof decreases upwards. Specifically, the fourth body angle m4 may be an angle such that the cross-sectional area of the installation partition wall 3211 decreases moving upwards.
By virtue of formation of the fourth body angle m4, the metal mold configured to form the inner surface of the installation partition wall 3211 may be more easily removed.
Meanwhile, the metal mold, which forms the outer surface of the installation partition wall 3211, may be removed in the width direction of the base 310. The outer wall of the installation partition wall 3211 may define a fifth body angle m5 relative to the metal mold removal direction MR.
The fifth body angle m5 may be an angle such that the distance between two opposing outer surfaces of the installation partition wall 3211 increases in the metal removal direction MR.
The length of the installation partition wall 3211, in a direction perpendicular to a direction in which the installation partition wall 3211 is depressed, may decrease in the direction in which the installation partition wall 3211 is depressed. In other words, the length of the installation partition wall 3211, in a direction perpendicular to the metal mold removal direction MR, may increase in the metal mold removal direction MR.
When the fifth body angle m5 is formed as described above, there is an effect of being capable of more easily removing the metal mold configured to form the outer surface of the installation partition wall 3211.
The directions or sloping directions of the above-mentioned body angles m1, m2, m3, m4 and m5 may not be limited to the above embodiment, and may be changed so as to allow metal molds configured to form the surfaces to be more easily removed.
When the body angles m1, m2, m3, m4 and m5 are provided as described above, there may be effects of allowing the metal molds configured to form the circulation duct 320 to be more easily removed and of reducing occurrence of defective circulation ducts.
Furthermore, since the metal mold is easily removed, there are effects of improving quality of the inner lateral surface and the outer lateral surface of the circulation duct 320 and of allowing air to smoothly flow overall.

A conventional laundry treatment apparatus is constructed such that the compressor installation portion is additionally coupled to the base configured to form the bottom surface. In contrast, when the compressor installation portion 312 is formed integrally with the base 310 as in the present disclosure, it is possible to more efficiently reduce vibration generated by the compressor 342. Furthermore, considering that the compressor 342 is a component which generates a large amount of vibration, there is an effect of ensuring stability of the compressor 342.
The compressor installation portion 312 may be positioned lower than the circulation duct bottom surface 325. In other words, the compressor installation portion 312 may be formed by depressing a portion of the base bottom 311. In other words, the compressor installation portion 312 may be positioned closer to the ground than the circulation duct bottom surface 325. Furthermore, the compressor installation portion 312 may be spaced farther away from the inner case than the circulation duct bottom surface 325.
Generally, the compressor 342 is one of components which generate a large amount of vibration or noise. Here, when the compressor installation portion 312 is disposed at a low position, there is an effect of ensuring structural stability, regardless of vibration generated by the compressor 342.
The compressor installation portion 312 may include an installation protrusion 3121 which projects from the base bottom 311. The installation protrusion 3121 may be coupled to the compressor 342. The installation protrusion 3121 may include a plurality of installation protrusions, which are to be coupled to multiple points of the compressor 342.
Furthermore, the compressor installation portion 312 may include a circumferential rib 3123 which projects upwards from the base bottom 311 and has a circular shape and which is positioned below the compressor. In addition, the compressor installation portion 312 may include a radial rib 3124 which projects upwards from the base bottom 311 and radially extends from the circumferential rib 3123.
The circumferential rib 3123 and the radial rib 3124 may be disposed below the compressor 3124 so as to reduce vibration or noise generated by the compressor 342. The circumferential rib 3123 and the radial rib 3124 may be disposed between the plurality of installation protrusions 3121. The circumferential rib 3123 and the radial rib 3124 may be disposed so as to connect the plurality of installation protrusions 3121 to each other.
The circumferential rib 3123 and the radial rib 3124 are capable of improving structural stability of the compressor installation portion 312. The circumferential rib 3123 and the radial rib 3124 may form an installation surface 3122 which supports the lower side of the compressor 342 or is disposed below the compressor 342.
The compressor installation portion 312 may be formed integrally with the base bottom 311. Here, the compressor installation portion 312 may be molded by means of a metal mold. The metal mold, which forms the compressor installation portion 312, may be removed in the height direction of the cabinet 100. The drawing illustrates the direction MR in which the metal mold configured to form the compressor installation portion is removed.
The base 310 may include the controller installation portion 313 which provides a space in which the controller 700 is installed. The compressor installation portion 312 may be disposed so as to overlap at least a portion of the controller installation portion 313 in the width direction of the base.
As described above, both the controller installation portion 313 and the compressor installation portion 312 may be formed by the base 310 and may be arranged in the width direction, thereby conveying an effect of improving availability of space.
The base 310 may include a reinforced partition wall 3125 which extends upwards from the base bottom 311 and is disposed between the circulation duct 320 and the compressor installation portion 312. The reinforced partition wall 3125 may form one surface of the compressor installation portion 312.
The reinforced partition wall 3125 may extend to a predetermined height. The reinforced partition wall 3125 may extend higher than the compressor installation portion 312. The reinforced partition wall 3125 may be formed by a metal mold configured to form the compressor installation portion 312.
The reinforced partition wall 3125 may increase the mass of the periphery of the compressor installation portion 312. Since the mass of the periphery of the compressor installation portion 312 increases, vibration generated by the compressor 342 may be more efficiently reduced.
The reinforced partition wall 3125 may be disposed in front of the compressor installation portion 312. Consequently, the reinforced partition wall 3125 has an effect of reducing noise generated by the compressor 342 to a certain extent.
The reinforced partition wall 3125 may include a reinforced partition wall surface 3125s on a surface thereof opposed to the compressor 342. The reinforce partition wall surface 3125s may define a predetermined angle relative to the metal mold removal direction MR. Accordingly, the reinforced partition wall surface 3125s may define a predetermined angle relative to the height direction, thereby allowing the metal mold to be more easily removed.
The base 310 may include a support partition wall 3126 which extends upwards from the base bottom 311 and forms another surface of the compressor installation portion 312.
The support partition wall 3126 may be disposed so as to be spaced apart from the reinforced partition wall 3125. When the reinforced partition wall 3125 is disposed in front of the compressor 342, the support partition wall 3126 may be disposed behind the compressor 342.
The support partition wall 3126 may also extend to a predetermined height, similar to the reinforced partition wall 3125. Specifically, the support partition wall 3126 may also increase mass of the periphery of the compressor installation portion 312, thereby reducing vibration generated by the compressor 342. Furthermore, the support partition wall 3126 may reduce noise generated by the compressor 342.
The support partition wall 3126 may also be formed by the metal mold configured to form the compressor installation portion 312.
The base 310 may further include a connecting partition wall 3127 connecting the reinforced partition wall 3125 to the support partition wall 3126. The connecting partition wall 3127 may extend upwards from the base bottom 311. The connecting partition wall 3127 may form one surface of the compressor installation portion 312.
The connecting partition wall 3127 may extend upwards from the base bottom 311 to isolate the compressor installation portion 312 from the controller installation portion 313. In other words, the connecting partition wall may isolate the space for installation of the compressor 342 from the space for installation of the controller 700 to prevent an electrical signal of the controller 700 from interfering with the compressor 342.
The base 310 may include a handle 3128 which is formed behind the compressor installation portion 312 and the support partition wall 3126. The handle 3128 may be formed in a shape which is easily gripped by a worker.
A worker may grip the handle 3128 when moving the base molding M in which the base 310 and the circulation duct 320 are integrally formed. The handle 3128 may have an effect of improving productivity of a worker.
The handle 3128 may be formed integrally with the base 310. In other words, the handle 3128 may be formed by the metal mold configured to form the base 310. The handle 3128 may be disposed so as to overlap the compressor installation portion 312 in the forward/backward direction. The handle 3128 may increase mass of the periphery of the compressor installation portion to reduce vibration generated by the compressor 342.

The controller installation portion 313 may be indirectly formed by formation of the circulation duct 320. In other words, it is understood that the controller installation portion 313 is naturally formed in the course of integrally forming the base 310 and the circulation duct 320 without providing an additional component to form the controller installation portion 313.

The controller-fixing protrusion 3137 may be formed at the side opposite to the controller-seating protrusion 3136. The controller-seating protrusion 3136 may secure the front side of the controller 700 while the controller-fixing protrusion 3137 may secure the rear side of the controller 700.
The forward/backward movement of the controller 700 may be limited by the controller-seating protrusion 3136 and the controller-fixing protrusion 3137. A detailed structure of the controller-fixing protrusion 3137 will be described later.
The description of the structure and the configuration of the controller-seating protrusion 3136 and the controller-fixing protrusion 3137 is merely given in connection with an embodiment of the present disclosure. In other words, the projection or depression of the controller-seating protrusion 3136 and the controller-fixing protrusion 3137 may be appropriately changed.
Furthermore, the controller 700 may include the support 3132 which projects from the lateral surface of the controller 700. The support 3132 may extend in the forward/backward direction. The controller installation portion may further include the controller rib 3134 which projects from the inner lateral wall of the controller installation portion 313.

The noise filter 390 may be configured to eliminate noise from electrical signals which are transmitted to and received from the compressor 342, the fan installation portion 350 and the like, in addition to the controller 700.
The noise filter 390 may be disposed close to the controller 700. When the noise filter 390 is disposed close to the controller 700, electrical connection may be facilitated. The noise filter 390 may be disposed behind the controller 700. Particularly, the noise filter 390 may be disposed close to the controller 700 in the forward/backward direction.

The noise filter installation portion 3138 may be disposed behind the controller installation portion 313. The noise filter installation portion 3138 may also be formed by means of the metal mold configured to form the controller installation portion 313.
Here, in order to form the noise filter installation portion 3138 which projects from the base bottom 311, the controller installation portion 313 may include a noise filter guide 3139 configured to assist in removal of the metal mold. The noise filter guide 3139 may project from the base bottom 311, and may extend in the forward/backward direction. The noise filter guide 3139 may be disposed so as to overlap the noise filter installation portion 3138 in the forward/backward direction.
The noise filter guide 3139 may extend in the metal mold removal direction MR.

Specifically, the noise filter guide 3139 may be constructed such that the cross-sectional area thereof increases as the distance from the noise filter installation portion 3138 increases. When the cross-sectional area of the noise filter guide 3139 varies in the above-described manner, there is an effect of allowing the metal mold configured to form the noise filter installation portion 3138 to be more easily removed.

Here, the inner side and the outer side may be defined as the inner side and the outer side based on the depression direction. Furthermore, the inner side may mean the front side, and the outer side may mean the rear side.
As described above, when the inner perimeter S2 is less than the outer perimeter S1, there is an effect of allowing the metal mold configured to form the controller installation portion 313 to be more easily removed.

As described above, the controller installation upper surface 313b may be formed by the bottom surface of the heat exchange installation portion. Accordingly, the upper surface of the partition wall defining the bottom surface of the heat exchange installation portion 3212 may be defined as the bottom surface of the heat exchanger installation portion 3212, and the lower surface of the partition wall may be defined as the controller installation upper surface 313b.
The height 3134L of the controller rib 3134, which is the length of the controller rib 3134 in the height direction of the cabinet 100, may increase in the direction in which the controller installation portion 313 is depressed.
The controller rib 3134 may also be injection-molded by means of a metal mold at the time of formation of the controller installation portion 313. Here, in order to allow the metal mold configured to form the controller rib 3134 to be easily removed, the height 3134L of the controller rib may decrease in the metal mold removal direction.
The controller rib 3134 may extend backwards from the front surface of the controller installation portion 313.
The cross-sectional area of the noise filter guide 3139 may increase in the direction in which the controller installation portion 313 is depressed. That is, the cross-sectional area of the noise filter guide 3139 may increase in the forward direction. In other words, the cross-sectional area of the noise filter guide 3139 may increase in a direction far away from the noise filter installation portion.

Specifically, the upper surface of a certain partition wall may form the heat exchanger installation portion 3212, and the lower surface of the certain partition wall may form the controller installation portion 313.
As described above, since the controller installation portion 313 and the water reservoir 326 are densely disposed in a limited space, it is possible to utilize the internal space in the machine compartment more efficiently. Furthermore, since an additional part is not necessary to construct each of the components, it is possible to improve assembly efficiency. Furthermore, since both the controller installation portion 313 and the water reservoir 326 are integrally formed on the base and the circulation duct 320, there is an effect of preventing water leakage.
Hereinafter, the present disclosure will be described with reference to
The laundry treatment apparatus according to an embodiment of the present disclosure may include the circulation duct 320, which is provided in the machine compartment 300 and is open at the upper surface thereof and which receives therein the evaporator and the condenser and provides the flow channel in which the air in the laundry treatment space is circulated, and the base 310, which is provided in the machine compartment and supports the lower portion of the circulation duct 320.

The fan housing 351 may be configured to allow the circulation duct 320 to communicate with the laundry treatment space 220. Specifically, the fan housing 351 may allow the circulation duct 320 to communicate with the laundry treatment space 220, thereby minimizing loss of flow caused by the blower fan 353.
In the conventional laundry treatment apparatus 1, the fan housing does not connect the circulation duct to the laundry treatment space 220. Particularly, in the conventional laundry treatment apparatus 1, the fan configured to generate airflow is disposed in front of the circulation duct. Accordingly, there is a problem in that loss of airflow occurs. In contrast, the laundry treatment apparatus according to an embodiment of the present disclosure is configured such that the fan housing 351 allows the circulation duct 320 to communicate with the laundry treatment space 220, thereby making it possible to prevent loss of flow.

Specifically, the air discharge portion 323 may be configured to have a smaller flow area than the duct body 321. Consequently, the speed of the air flowing through the air discharge portion 323 may increase. Furthermore, there is an effect of reducing loss of air flowing through the air discharge portion 323.
The duct body 321 and the air discharge portion 323 may be formed integrally with each other. Therefore, there is an effect of making it possible to prevent air leakage or loss of flow from occurring at the boundary between the duct body 321 and the air discharge portion 323.
The fan housing 351 may include a first housing 354, which is coupled to the air discharge portion 323, forms a portion a discharge flow channel configured to guide the air discharged from the air discharge portion 323 to the laundry treatment space 220, and includes a fan housing discharge portion 3544 configured to discharge the air toward the inner case.
Furthermore, the fan housing 351 may include a second housing 355, which is coupled to the first housing 354 so as to define the discharge flow channel in conjunction with the first housing 354.
The first housing 354 may be directly coupled to the air discharge portion 323 so as to define a portion of the discharge flow channel. The first housing may be open at the side thereof that faces the second housing 355. The second housing 355 may be configured to shield the open area of the first housing 354.
When the fan housing 351 is divided into the first housing 354 and the second housing 355, as described above, there is an effect of facilitating a procedure of assembling the blower fan 353 installed to the fan housing 351. In other words, since the fan housing 351 is composed of the first housing 354 and the second housing 355, assembly efficiency may be improved.
The first housing 354 may include a first housing body 3541 defining a portion of the discharge flow channel. The first housing body 3541 may receive a portion of the blower fan 353. Particularly, the first housing body 3541 may receive the blower blade 3533.
Furthermore, the first housing 354 may include a fan housing introduction portion 3542 which extends toward the air discharge portion 323 from the first housing body 3541. The fan housing introduction portion 3542 may extend to have the shape of a pipe. The fan housing introduction portion 3542 may be directly connected to the air discharge portion 323.
An introduction seal 3561 may be provided between the fan housing introduction portion 3542 and the air discharge portion 323 in order to prevent leakage of air at the connecting point therebetween.

The fan housing discharge portion 3544 may be provided with a discharge seal 3563 configured to prevent air leakage. The discharge seal 3563 may be provided on the inner lateral surface of the fan housing discharge portion 3544. The discharge seal 3563 may be disposed between the fan housing discharge portion 3544 and the laundry treatment space 220 so as to prevent air leakage.

The blower blade (not shown) may be positioned opposite to the blower motor 3531 based on the second housing. The blower blade may be connected to the blower shaft 3532 and be rotated thereby. Accordingly, the blower blade may be positioned in the first housing 354.

The structures of the first housing fastener 3547 and the second housing fastener 3552 may be reversed, unlike the structures shown in the drawing.

The first housing fastener 3547 and the second housing fastener 3552 may be coupled to each other in a screw coupling manner as well as in a hook coupling manner.
A coupling seal 3562 may be provided between the first housing 354 and the second housing 355 in order to prevent air leakage through the connecting point therebetween. Specifically, the coupling seal 3562 may be manufactured into a shape surrounding the open rear surface of the first housing 354.
Referring to the enlarged view in
The circulation duct 320 may further include a discharge insert 3235, which is coupled to the first housing 354, in addition to the discharge coupler 3234. The discharge insert 3235 may project from one side of the duct body 321. Furthermore, the discharge insert 3235 may project from one side of the air discharge portion 323.

The second housing 355 may include a protection rib 3553 which projects from the second housing body 3551. The protection rib 3553 may be disposed above the noise filter 390. The noise filter 390 may be configured to eliminate noise from an electrical signal which is transmitted to and received from the controller 700.
The hot air, which has passed through the condenser 343, may pass through the fan housing 351. At this time, dew drops may be generated on the outer side of the fan housing 351 due to the hot air. In addition, there is the possibility that moisture contained in air flowing through the fan housing 351 is condensed on the outer side of the fan housing 351.
When the second housing 355 is coupled in the normal position, the protection rib 3553 may be disposed above the noise filter 390. In other words, the protection rib 3553 may prevent moisture from falling to the noise filter 390.
Referring to
The housing rib 3546 may be inserted into the hole or slit in the discharge insert 3235. The housing rib 3546 may extend in the height direction.
The first housing 354 may be coupled to or supported by the circulation duct 320 by means of the duct coupler 3543 and the housing rib 3546. The housing rib 3546 may serve to temporarily position the first housing 354 prior to coupling the first housing 354 to the circulation duct 320 using an additional fastening element.

Referring to
The controller 700 may be coupled to the first housing fixture 3548 and the guide 3133 so as not to be moved in the forward/backward direction. In other words, the controller 700 may be fixed in the normal position by coupling between components thereof without using additional fastening elements such as a bolt and a nut.
Specifically, the controller-fixing protrusion 3137 may be inserted into the first housing fixture 3548. On the contrary, the first housing fixture 3548 may be inserted into or supported by the controller-fixing protrusion 3137. The manner in which the controller-fixing protrusion 3137 and the first housing fixture 3548 are coupled to each other can be designed in a variety of ways.
The detailed coupling procedure will now be described. When the first housing 354 is coupled to the circulation duct 320, the first housing fixture 3548 may be coupled to the controller-fixing protrusion 3137 in an engagement manner. Accordingly, the controller 700 may be coupled to the controller installation portion 313 without using separate bolts and nuts.
Specifically, the front side of the controller 700 may be coupled to the guide 3133, and the rear side of the controller 700 may be coupled to the first housing fixture 3548. Furthermore, the two lateral surfaces of the controller 700 may be supported by the controller rib 3134. By virtue of the support and coupling, the controller 700 may be fixed in the controller installation portion 313. The controller 700 in the state of being fixed may define a predetermined angle relative to the base bottom 311.
Referring to
The noise filter 390 may be installed behind the controller 700. Furthermore, the noise filter 390 may be disposed below the protection rib 3533. The protection rib 3533 may prevent moisture from falling to the noise filter 390.
The protection rib 3553 may include a sloping surface 3553a, which extends so as to be sloped downwards from a position above the noise filter 390, and a discharge surface 3553b, which vertically extends downwards from the lower end of the sloping surface 3553a.
The protection rib 3553 may be disposed so as to overlap the noise filter 390 in the height direction of the cabinet 100. When the protection rib 3553 is disposed so as to overlap the noise filter 390 in the height direction, the protection rib 3553 is capable of more efficiently preventing moisture from falling to the noise filter 390.
Furthermore, the noise filter 390 may be disposed so as to overlap the sloping surface 3553a in the height direction. The water falling on the sloping surface 3553a may move in a direction of escaping from the noise filter 390 by the slope of the sloping surface 3553a.
The lower end of the sloping surface 3553a may be provided with the discharge surface 3553b. The discharge surface 3553b may discharge the moisture, moved along the sloping surface 3553a, to the outside of the noise filter 390. In other words, the sloping surface 3553a and the discharge surface 3553b are capable of efficiently preventing moisture generated above the noise filter 30 from entering the noise filter 390.
The blower fan 353 may be disposed so as to overlap the condenser 343 and the evaporator 341 in the forward/backward direction. In contrast, because a conventional laundry treatment apparatus is constructed such that the evaporator and the condenser are spaced apart from each other in the height direction, loss of flow may occur.
On the contrary, because the laundry treatment apparatus according to an embodiment of the present invention is constructed such that the condenser 343 or the evaporator is disposed so as to overlap the blower fan 353 in the forward/backward direction, it is possible to prevent occurrence of loss of flow. In addition, because the blower fan 353 is disposed behind the evaporator 341 or the condenser 343, there is an effect of making it possible to more easily control airflow supplied to the laundry treatment space 220.
Furthermore, the fan housing 351 may be disposed so as to overlap the compressor 342 in the width direction of the base 310. In other words, the fan housing 351 may be disposed so as to overlap the compressor in the lateral direction. Because the fan housing 351 is disposed at a rear side, the fan housing 351 may overlap the compressor 342 in the width direction, and space utilization may be improved.
Furthermore, the fan housing 351 may be disposed so as to overlap at least a portion of the steam supply 800 in the width direction of the base. Because a conventional laundry treatment apparatus is constructed such that the fan housing is disposed in front of the machine compartment, it is difficult to dispose the fan housing 351 in the state of overlapping the steam supply in the width direction. However, because the present disclosure is constructed such that the fan housing 351 is disposed behind the circulation duct 320, the fan housing 351 may overlap the steam supply 800 in the width direction.
The steam supply 800 and the fan housing 351 are components configured to create hot air or steam to be supplied to the laundry treatment space 220. Specifically, when the components configured to create hot air or steam to be supplied to the laundry treatment space 220 are disposed so as to overlap each other in the width direction, the components may be easily connected to the through hole formed at a rear side of the bottom surface of the laundry treatment space. Accordingly, there is an effect of efficiently improving space utilization.
Furthermore, when the steam supply 800 and the fan housing 351 are disposed so as to overlap each other in the width direction, it is easy to dispose the through hole, which communicates with the laundry treatment space 220, close to the steam supply 800 and the fan housing 351. In other words, convenience of production and assembly efficiency may be improved.

The air extension pipe 3231 may be configured to guide the air in the duct body 321 in the backward direction. Meanwhile, the air discharge pipe 3232 may be configured to discharge the air in the duct body 321 to the outside of the duct body 321.
The air extension pipe 3231 and the air discharge pipe 3232 may be formed integrally with the duct body 321. Particularly, the duct body 321, the air extension pipe 3231, and the air discharge pipe 323 may be formed integrally with one another using a metal mold.
Referring to
Accordingly, an air discharge pipe parting line 3236 may be formed at the point at which the air discharge pipe 3232 is connected to the air extension pipe 3231. Based on the air discharge pipe parting line 3236, the front side of the air discharge portion 323 may be defined as the air discharge pipe 3232, and the front side of the air discharge portion 323 may be defined as the air extension pipe 3231.
Accordingly, because the direction in which the metal mold for the air extension pipe 3231 and the direction in which the metal mold for the air discharge pipe 3232 are different from each other, the air extension pipe 3231 and the air discharge pipe 3232 may be different from each other in gradient of the diameter. Particularly, the air extension pipe 3231 and the air discharge pipe 3232 may be different from each other in gradient of the inside diameter.
Generally, the term “inside diameter” may mean the diameter of the inside of the pipe shape. In other words, the term “inside diameter” may mean the diameter of the pipe shape. However, the air extension pipe 3231 may be formed to have the shape of a bell mouth rather than the shape of a pipe. Accordingly, in this disclosure, the inside diameter may be understood to mean the cross-sectional area of the flow channel in which air flows.
In other words, in this disclosure, the inside diameter may be understood to mean the height or the width of the cross-section of the flow channel perpendicular to the direction in which air flows or in which the pipe extends. Specifically, when the flow channel in which air flows is cut along a plane perpendicular to the forward/backward direction, the width or the height of the cross-section of the flow channel may be referred to as inside diameter.
Each of the inside diameters of the air extension pipe 3231 and the air discharge pipe 3232 may increase in the direction in which the corresponding metal mold is removed. For example, the metal mold configured to form the air extension pipe 3231 may be removed in the forward direction. Here, the inside diameter of the air extension pipe 3231 may increase moving forwards.
Meanwhile, the metal mold configured to form the air discharge pipe 3232 may be removed in the backward direction. Here, the inside diameter of the air discharge pipe 3232 may increase moving backwards.
When both the pipes are constructed in the fashion described above, the inside diameter of the portion at which the air extension pipe 3231 and the air discharge pipe 3232 are connected to each other may be smallest in the entire air discharge portion 323. Specifically, the inside diameter of the portion at which the air extension pipe 3231 and the air discharge pipe 3232 are connected to each other may be smallest in the air extension pipe 3231 and the air discharge pipe 3232. In other words, the diameter of the air discharge pipe parting line 3236 may be smallest among the inside diameters of the air discharge portion 323.
In other words, the interior cross-sectional area of the air extension pipe 3231 may decrease in the direction in which the air extension pipe 3231 extends, and the interior cross-sectional area of air discharge pipe 3232 may increase in the direction in which the air discharge pipe 3232 extends. Here, the extension direction may mean the backward direction. Furthermore, the extension direction may mean the direction in which the air discharge portion 323 extends.
The first housing 354 may communicate with the air discharge pipe 3232. The fan housing introduction portion 3542 may be coupled to the air discharge pipe 3232 so as to communicate therewith. In other words, when the duct coupler 3543 and the discharge coupler 3234 are coupled to each other, the fan housing introduction portion 3542 and the air discharge pipe 323 may be disposed so as to communicate with each other.
