The present disclosure relates to a laundry treating apparatus, and more particularly, to a laundry treating apparatus that may press laundry such as at least two or more pants or use steam and a heating wire to remove wrinkles thereof.
In general, a laundry treating apparatus is configured to perform various laundry-related treatments (washing, drying, deodorization, wrinkle removal, etc.) and may include a washing apparatus for washing laundry, a dryer for drying laundry, a combined drying and washing machine for washing and drying functions, a drying apparatus for drying wet laundry, a refresher for removing odors from laundry or wrinkles therefrom, a steamer to remove unnecessary wrinkles, etc.
A refresher is an apparatus for making a state of laundry pleasant and fresh, and performs functions such as drying laundry, supplying fragrance to laundry, preventing static electricity from occurring in laundry, or removing wrinkles from laundry.
Further, the laundry treating apparatus is in the trend of being developed so that washing, drying, deodorization and wrinkle removal of laundry may be solved with one apparatus. However, because the laundry treating apparatus uses a drum in which laundry is accommodated and a driving device for rotating the drum, deodorization or wrinkle removal of laundry is insufficient.
In order to solve this problem, a laundry treating apparatus having a steamer and a refresher is disclosed in Korean Patent Application Publication No. 10-2014-0184457. The laundry treating apparatus has a treating chamber that treats laundry with air circulation or steam, and a separate wrinkle removal module that removes wrinkles by pressing laundry inside the treating chamber. The laundry treating apparatus as described above discloses a structure in which the wrinkle removal module that removes wrinkles by pressing laundry may treat only singe laundry. In this case, when it is necessary to treat a plurality of pants to be treated, there is a problem that it takes a lot of time as the module has to treat the plurality of pants sequentially one by one.
Further, referring to
An auxiliary hanger 50 for fixing the laundry, and a presser 60 disposed under the auxiliary hangers to press the laundry are provided inside the door. The auxiliary hanger 50 includes a hanger 522, and a hanger support 521 disposed on the door and supporting the hanger 522 thereon. The presser 60 includes a support 65 that supports the laundry at one face thereof, a pressing portion 66 that is pivotably configured and moves toward the support 65 and presses the other face of the laundry, and an anti-torsion portion 67 disposed under the pressing portion 66 to prevent torsion of the laundry.
As a result, the laundry treating apparatus is able to remove wrinkles and perform deodorizing at the same time by supplying hot-air from the machine chamber located under the cabinet to the laundry or pressing the laundry in a state when the laundry is disposed in the receiving space 14.
Further, in the laundry treating apparatus, hot-air or moisture is supplied to the laundry while the laundry is unfolded by its own weight and inside the cabinet, so that drying and deodorization or wrinkle removal of the laundry may be achieved. Further, when the pressing portion 66 presses the face of the laundry, the wrinkles of the laundry may be effectively removed, or creases (wrinkles intentionally formed in the laundry) may be formed, and thus ironing may be omitted after washing or drying is completed.
However, in the conventional the laundry treating apparatus, there is no separate member between the pressing portion 66 and the support 65. Thus, there is a problem that only one laundry is pressed, thereby reducing efficiency.
Further, in the conventional laundry treating apparatus, the pressing portion 65 is pressed toward a side of the laundry P while being pivoted, so that the pressing portion 65 sequentially presses the laundry from one side of the laundry P to the other side thereof.
Thus, a relatively large amount of pressure is applied to a portion of the laundry P close to the pressing portion 65, while a relatively small amount of pressure is applied to a portion of the laundry far away from the pressing portion 65. Thus, there is a problem in that the laundry is not pressed evenly.
Furthermore, in the process of the pressing portion 65 pressing the laundry P, there is a problem in that the laundry P is distorted or displaced due to being pushed by the pressing portion 65.
Further, the conventional the laundry treating apparatus has a problem in that the laundry cannot be fixed even when the laundry P is held on a laundry hanger, and thus the position of the laundry is changed when the laundry is pressed. As a result, in the conventional laundry treating apparatus, the pressing portion 65 causes more wrinkles in the laundry P, or causes creases to be formed in a direction completely different from the intended direction.
Further, the conventional laundry treating apparatus has a problem in that when the laundry is a lower garment such as pants and thus has regions partitioned from each other, the pressing portion may not press each of the partitioned regions in an individual manner. For example, in the conventional the laundry treating apparatus, when the laundry is a lower garment such as pants, a first portion of the laundry corresponding to a left leg and a second portion thereof corresponding to a right leg are pressed in an overlapped manner.
Therefore, there is a problem that in the process of pressing the laundry, the first portion and the second portion overlap each other in a non-matching manner or creases occur in an unintended area of the laundry due to the displacement of the laundry.
Further, there is a problem in that refreshing as drying and deodorization is not performed reliably because hot-air or moisture steam is not supplied into a region in which the first portion and the second portion contact each other.
A first purpose of the present disclosure is to provide a laundry treating apparatus that treats a plurality of garments whose wrinkles must be removed via pressing in a short time.
A second purpose of the present disclosure is to provide a laundry treating apparatus capable of treating a single garment or a plurality of garments at the same performance even when the single garment or the plurality of garments is simultaneously pressed and treated.
A third purpose of the present disclosure is to provide a laundry treating apparatus that removes wrinkles by pressurizing a plurality of garments while the plurality of garments placed inside a cabinet is being treated.
A fourth purpose of the present disclosure is to provide a laundry treating apparatus that may evenly press partitioned areas of laundry such as a lower garment having the partitioned areas.
A fifth purpose of the present disclosure is to provide a laundry treating apparatus that may evenly supply at least one of steam or hot-air to partitioned areas of laundry.
A sixth purpose of the present disclosure is to provide a laundry treating apparatus that may prevent a position of laundry from being changed in a process of pressing the laundry.
A seventh purpose of the present disclosure is to provide a laundry treating apparatus by which a crease may be accurately formed in an area intended by a user.
The purposes of the present disclosure are not limited to the purposes mentioned above, and other purposes that are not mentioned will be clearly understood by those skilled in the art from the following description.
In order to achieve the above purposes, a laundry treating apparatus according to the present disclosure includes a cabinet having a front opening; a door assembly for opening and closing the opening; a first laundry treating chamber defined in the cabinet to receive laundry therein, wherein the first laundry treating chamber communicates with an outside of the cabinet through the opening; and a machine chamber in communication with the first laundry treating chamber, wherein the machine chamber receives therein at least one of a steam supply to supply steam to the first laundry treating chamber and an air supply for circulating air, wherein the door assembly includes: a first panel having a second laundry treating chamber defined therein to treat laundry therein, wherein one face of the first panel is open and the first panel is pivotably connected to the cabinet; a second panel pivotably connected to the first panel for opening and closing the open one face of the first panel; and a partitioning plate disposed between the first panel and the second panel to press each of first laundry held on the first panel and second laundry held on the second panel. Thus, at least two garments may be treated in the door assembly at the same time.
In order to achieve the first purpose, one side of the partitioning plate is hinge-coupled to one side of the first panel or the second panel, wherein the other side of the partitioning plate is removably coupled to the other side of the first panel or the second panel. Thus, at least two garments may be held in the door assembly.
In order to achieve the first purpose, the partitioning plate includes a fixing protrusion to fixe or separate the partitioning plate to or from one side of the first panel or one side of the second panel. Thus, at least two garments may be treated in the door assembly.
In order to achieve the first and second purposes, when the partitioning plate is fixed to the first panel or the second panel, a spacing between the partitioning plate and the first panel or the second panel is kept to be constant. Thus, even when a single garment is held in the door assembly, the garment may be uniformly pressed.
In order to achieve the first and second purposes, when the first panel is fixed to the second panel, each of a spacing between the first panel and the partitioning plate and a spacing between the partitioning plate and the second panel is kept to be constant. Thus, each of at least two garments may be uniformly pressed.
A first fixing member for fixing laundry thereto, and a first base plate in close contact with the partitioning plate to press the laundry fixed to the first fixing member are disposed on an inner face of the first panel, wherein a second fixing member for fixing laundry thereto, and a second base plate in close contact with the partitioning plate to press the laundry fixed to the second fixing member are disposed on an inner face of the second panel. Thus, a plurality of garments may be held in the door assembly.
The second panel is disposed between the first laundry treating chamber and the second laundry treating chamber. A communication hole for communicating the first laundry treating chamber and the second laundry treating chamber with each other is defined in the second panel. Thus, the laundry in the second chamber may be treated using air or steam flowing in the first chamber.
The partitioning plate has a rectangular plate shape, and has an opening defined in a center thereof and extending in a front and rear direction. Thus, the steam in the second chamber may flow through the partitioning plate.
The machine chamber receives therein: a first laundry treating chamber supply pipe to circulate air in the first laundry treating chamber or to supply steam generated from a steam generator to the first laundry treating chamber; and a second laundry treating chamber supply pipe to supply steam generated from the steam generator to the second laundry treating chamber. Thus, separate steam may be fed to the second chamber.
The second laundry treating chamber supply pipe is a pipe branched from a downstream portion of the first laundry treating chamber supply pipe. Thus, a structure of the existing machine chamber may be used.
An adjustment cover configured for controlling steam supply to the second laundry treating chamber supply pipe is disposed at one side of the first laundry treating chamber supply pipe at which the second laundry treating chamber supply pipe is connected to the first laundry treating chamber supply pipe. Thus, the steam supply to the second chamber may be controlled.
A second laundry treating chamber supply hole is defined in a top of the machine chamber to supply steam flowing in the second laundry treating chamber supply pipe to the door assembly. Thus, the steam may be fed to the second chamber.
The door assembly has a door inflow hole defined therein for supplying steam discharged from the second laundry treating chamber supply hole to the second laundry treating chamber. Thus, the steam from the machine chamber may be supplied to the door assembly.
A door inflow hole through which steam flowing through the second laundry treating chamber supply hole flows into the second laundry treating chamber is defined in a bottom of the second panel, wherein a door discharge hole through which steam flowing through the second laundry treating chamber is exhausted to the first laundry treating chamber is defined in a top of the second panel. Thus, the steam may be fed to the second chamber or may be discharged out of the second chamber.
A door inflow hole-gasket is disposed on the second panel, wherein when the door assembly closes the cabinet, the door inflow hole-gasket seals a space between the door inflow hole and the second laundry treating chamber supply hole. Thus, the steam may be stably fed to the second chamber.
In order to achieve the third purpose, the second panel pivots in a front direction of the door assembly. Thus, the second chamber may be used in a separate manner from the first chamber.
The apparatus according to the present disclosure further comprises: a cabinet hinge pivotably connecting the door assembly to the cabinet; an assembly hinge pivotably connecting the second panel to the first panel; and a steam supply for supplying steam generated from the steam generator to the second laundry treating chamber through the cabinet hinge and the assembly hinge.

Advantages and features of the present disclosure, and a method of achieving them will become apparent with reference to embodiments as described below in detail with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below, but may be implemented in a variety of different forms. Only these embodiments are provided to allow the present disclosure to be complete, and to completely inform those of ordinary skill in the technical field to which the present disclosure belongs of the scope of the present disclosure. The present disclosure is only defined by a scope of the claims. The same reference numerals refer to the same components throughout the specification.
Expressions referring to directions such as “front (F)/rear (R)/left (Le)/right (Ri)/upper (U)/down (D)” are defined as indicated in the drawings. However, this may merely ensure that the present disclosure is clearly understood. In another example, each of the directions may be defined in a manner different from a manner as indicated in the drawings based on a reference position.
Further, herein, in various embodiments, the same and similar reference numbers are allocated to the same and similar components, and descriptions thereof in a previous drawing is equally applied to descriptions thereof in a subsequent drawing. A singular expression of a component used in the present specification includes a plural expression thereof unless clearly mentioned otherwise in a context. Further, in describing the embodiment disclosed in the present specification, when it is determined that a detailed description of a related known component may obscure gist of the embodiment disclosed in the present specification, the detailed description thereof will be omitted. Further, it should be noted that the accompanying drawings are set forth for easy understanding of the embodiments disclosed in the present specification, and a technical spirit disclosed in the present specification is not limited to the accompanying drawings.
Hereinafter, embodiments disclosed in the present specification will be described in detail with reference to the accompanying drawings.
The machine chamber 20 may include at least one of an air supply 30 supplying air (heated air or non-heated air) to a receiving space 14 of a first laundry treating chamber 11 and a steam supply 40 supplying moisture (steam or mist) to the receiving space 14.
To this end, the first laundry treating chamber 11 has an air outlet 36 defined therein that discharges air to the machine chamber 20, and an air inlet 37 defined therein that receives air from the machine chamber 20, and a steam supply hole 42 defined therein for receiving moisture or steam from the machine chamber 20.
Because the machine chamber 20 generates hot-air having a relatively lower density than that of air, the machine chamber 20 may be disposed under the first laundry treating chamber 11 so that the hot-air may be completely supplied to the receiving space 14.
The machine chamber 20 may include at least one of the air supply 30 supplying air (heated air or non-heated air) to the receiving space 14, and the steam supply 40 supplying moisture (steam or mist) to the receiving space 14.
Hereinafter, for convenience of description, an example in which the machine chamber includes both the air supply 30 and the moisture supply 40, the air supply 30 supplies hot-air to the receiving space 14 and the steam supply 40 supplies steam to the receiving space 14 will be described.
The air supply 30 may include a first laundry treating chamber supply pipe 24, which circulates air inside the receiving space 14, a heat-exchanger 31 which exchanges heat with air flowing along the first laundry treating chamber supply pipe 24, and a blowing fan 32 to allow air inside the receiving space 14 to flow along the first laundry treating chamber supply pipe 24.
The first laundry treating chamber supply pipe 24 communicates with an interior of the receiving space 14 through the air outlet 36 and the air inlet 37 disposed in the receiving space 14.
The air outlet 36 and the air inlet 37 may pass through a bottom face of the receiving space 14 and communicate the receiving space 14 and the machine chamber 20. Therefore, when one end of the first laundry treating chamber supply pipe 24 placed inside the machine chamber 20 is connected to the air inlet 37 and the other end thereof is connected to the air outlet 36, the first laundry treating chamber supply pipe 24 is able to communicate with the interior of the receiving space 14.
The heat-exchanger 31 refers to means for dehumidifying and heating air introduced into the first laundry treating chamber supply pipe 24.
When the heat-exchanger is embodied as the heat pump, the heat-exchanger 31 may include an evaporator (E, 311) disposed inside the first laundry treating chamber supply pipe 24, a condenser (C, 312) disposed inside the first laundry treating chamber supply pipe 24, and a compressor (P, 33) and an expansion valve (Ex, 34) located outside the first laundry treating chamber supply pipe 24.
The evaporator E, the compressor P, the condenser C, and the expansion valve Ex are connected to each other through a refrigerant pipe 35.
The compressor P refers to means of compressing refrigerant to high pressure so that the refrigerant may be circulated along the refrigerant pipe 35. The evaporator E refers to means to evaporate the refrigerant by absorbing heat from air inside the first laundry treating chamber supply pipe 24 and to dehumidify and cool the air. The condenser C refers to means of heating the air and condensing the refrigerant by releasing heat into air inside the first laundry treating chamber supply pipe 24.
The blowing fan 32 refers to means that is located inside the first laundry treating chamber supply pipe 24 to allow air inside the receiving space 14 to be circulated along the first laundry treating chamber supply pipe 24, and is located between the condenser C and the air outlet 36.
Therefore, when the blowing fan 32 is activated, air inside the first laundry treating chamber supply pipe 24 moves to the receiving space 14 through the air outlet 36, and the air inside the receiving space 14 is transferred to the first laundry treating chamber supply pipe 24 through the air inlet 37.
Air flowing into the first laundry treating chamber supply pipe 24 through the air inlet 23 is cooled while passing through the evaporator E. Air passing through the evaporator E is heated while passing through the condenser C.
When the air is cooled while passing through the evaporator E, the moisture contained in the air is removed (dehumidification), and the moisture (condensed water) removed from the air remains on a face of the evaporator or inside the first laundry treating chamber supply pipe.
When the condensed water remains inside the first laundry treating chamber supply pipe 24, the heat exchange efficiency of heat-exchanger 31 decreases. Thus, the laundry treating apparatus according to the present disclosure may further include a water discharger for removal of the condensed water generated by the evaporator E.
On one side of the first laundry treating chamber supply pipe 24 according to the present embodiment, a water collection pipe 37 for collecting the condensed water generated via the heat exchange with the evaporator E may be disposed. The condensed water collected by the water collection pipe 37 may flow to the water discharger.
The water discharger may include a water discharge tank 47 detachably disposed on the machine chamber door 22, and a water discharge pipe 477 and a water discharge pump 479 supplying the condensed water inside the first laundry treating chamber supply pipe 24 to the water discharge tank 47.
The water discharge tank 47 may have any shape as long as the tank may provide a space for storing liquid therein. However, it is preferable that the tank 47 includes a water discharge tank lid 471 for discharging the liquid stored in the water discharge tank 47, and a water discharge tank inlet 473 to which the water discharge pipe 477 is detachably connected.
A check valve (not shown) may be further disposed at the water discharge tank inlet 473. Thus, when the machine chamber door 22 opens the machine chamber 20, the water discharge pipe 477 may be separated from the water discharge tank inlet 473. The water discharge pipe 477 may be inserted into the water discharge tank inlet 473 when the machine chamber door 22 closes the machine chamber 20. Further, when the water discharge tank is separated from the machine chamber door, the water inside the water discharge tank may be prevented from leaking to the outside of the water discharge tank.
In one example, as shown in
The steam generator 41 refers to means for storing water. The heater 411 refers to means for changing water into steam by heating water stored in the steam generator 41. The steam supply pipe 417 refers to means for guiding the steam inside the steam generator 41 to the receiving space 14.
Therefore, the heater 411 is preferably disposed to be adjacent to the bottom face of the steam generator 41. The steam supply pipe 417 is preferably located on a top face (topmost level) of the steam generator 41.
The steam generator 41 is supplied with water through a water supply. The water supply may include the water supply tank 45 detachably disposed on the machine chamber door 22.
In this case, the steam generator 41 may be configured to further include a water supply tank connection pipe 413 that is connected to the water supply tank 45 when the machine chamber door 22 closes the machine chamber 20, and is separated from the water supply tank 45 when the machine chamber door 22 opens the machine chamber 20.
The water supply tank 45 may have any shape as long as liquid may be stored therein. However, it is preferable that the water supply tank 45 is configured to include a water supply tank lid 451 for supplying liquid into the water supply tank 45, a discharge hole (not shown) into which the water supply tank connection pipe 413 is inserted, and a water supply tank check valve 455 disposed at the discharge hole.
The configuration that the water supply tank 45 is disposed in a detachable manner on the machine chamber door 22 is made based on a case where the laundry treating apparatus 1000 according to the present disclosure is installed at a location far away from a water supply source (not shown).
That is, when the laundry treating apparatus 1000 is placed adjacent to the water supply source, the steam generator 41 may be controlled to receive water from the water supply source when needed. However, when a location where the laundry treating apparatus 1000 is installed is far away from the water supply source, the above-described control is impossible. Thus, the water supply tank 45 may solve such a problem.
In addition, the water supply tank 45 and the water discharge tank 47 may be combined into one storage tank rather than being separate components. In this case, the condensed water stored in the storage tank may be reused, or may be directly discharged to the outside through the water discharge pipe 477 without being stored in the storage tank.
The laundry treating apparatus 1000 according to this embodiment includes a cabinet 10 having a hollow interior and an open front face, and a door assembly 100 that opens and closes the open front face of the cabinet 10.
The cabinet 10 according to the present embodiment includes the first laundry treating chamber 11 in which laundry is held and is treated using steam or air circulation, and the machine chamber 20 in which a device for injecting steam or circulating air are installed.
The machine chamber 20 according to this embodiment includes a separation plate 23 covering a top (U) of the machine chamber 20 so as to distinguish between the machine chamber 20 and the first laundry treating chamber 11, and a machine chamber door 22 disposed on a front face of the machine chamber 20 and 23 to open and close the inside of the machine chamber 20. The separation plate 23 is placed on the top (U) of the machine chamber 20.

Referring to
The cabinet 10 is configured to form an exterior of the laundry treating apparatus 1000 and may have a height larger than a width. As a result, it is possible to prevent wrinkles from occurring in the laundry P because the laundry P having a large vertical dimension such as a lower garment such as pants is accommodated in the receiving space 14 while the laundry P is not folded.
The cabinet 10 may be made of metal. Alternatively, when the cabinet may maintain a strength thereof, the cabinet is made of resin material such as reinforced plastic.
The first laundry treating chamber 11 may further include an inner body 11a located inside the cabinet 10 to define the receiving space 14 therein. The inner body 11a may be made of a material which is not deformed or does not have a chemical reaction due to foreign matter discharged from laundry P or hot-air or moisture supplied from the machine chamber 20, and is capable of maintaining a strength. For example, the material may include styrene based resin such as ABS and ASA.
The inner body 11a is configured to communicate with the machine chamber 20 at one face or a bottom side of the inner body to receive hot-air or moisture from the machine chamber 20, or to discharge air to the machine chamber 20. To this end, the inner body 11a may have a plurality of through-holes 36, 37, and 42 defined therein communicating with the machine chamber 20.
In one example, the cabinet 10 may further include the machine chamber 20 separated from the receiving space 14. The machine chamber 20 may be placed under the receiving space 14 to supply heated air or steam which has relatively density than that of air.
That is, when the air supplied to the receiving space 14 from the machine chamber 20 is heated air or hot-air, and the moisture supplied to the receiving space 14 from the machine chamber 20 is steam, the hot-air or steam may be uniformly supplied into the receiving space 14 without a separate blowing device as long as the machine chamber 20 is positioned below the receiving space 14.
Unlike the door assembly 100 as described in
Because the door assembly 100 is configured to open and close the front face of the inner body 11a, the inner face of the inner body 11a and the inner face of the door assembly 100 may constitute an outer face of the receiving space 14. The ironing presser 60 may be configured to press the laundry P on both sides thereof to remove wrinkles generated in the laundry P or to form a crease intended by the user in the laundry P.
In other words, the ironing presser 60 may perform ironing, so that the user does not need to additionally perform additional ironing after drying and deodorization of the laundry P are finished.
The ironing presser 60 may press laundry P including upper and lower garments to be subjected to ironing.
Specifically, the ironing presser 60 may include a support body 61 disposed in one of the first laundry treating chamber 11 and the door assembly 100 to support laundry thereon, and a pressing body 62 configured to be pivotably moved toward the support body 61 to press laundry supported on the support body 61. Hereinafter, a case where the ironing presser 60 is disposed in the door assembly 100 will be described. Therefore, the door assembly 100 includes the ironing presser 60. That is, the ironing presser 60 is disposed in the door assembly 100 and thus becomes a part of the door assembly 100.
The support body 61 may be provided in a plate shape such that the laundry is not deformed when one face of the laundry is pressed against the pressing body 62. Specifically, the support body 61 may include a contact plate 612 configured to be in face-contact with the laundry P, and may further include a fixing groove 611 recessed along a longitudinal direction in the contact plate 612 so as to avoid a sewing line disposed in the laundry P or to concentrate an applied force onto both lateral ends of the laundry P.
Thus, when the pressing body 62 presses the support body 61, pressure is concentrated on the contact plate 612 so that the wrinkles of the laundry P are effectively removed, as well as the crease is clearly formed at both lateral ends of the laundry P. Furthermore, unintended wrinkles which may otherwise occur due to the sewing line may be prevented from being formed in the laundry P.
The pressing body 62 may be pivotably coupled to the support body 61, or may be pivotably coupled to the inner face of the inner body 11a on which the support body 61 is disposed or to the inner face of the door assembly 100. That is, the pressing body 62 may be coupled to any structure as long as the pressing body 62 may be pivotably moved toward or away from the support body 61.
The pressing body 62 may be pivotably coupled to a connection hinge 80 disposed at one side of at least one of the inner body 11a, the door assembly 100, and the support body 61.
That is, the connection hinge 80 may be disposed on the support body 61, or may be disposed on the inner body 11a on which the support body 61 disposed or may be disposed on the inner face of the door assembly 100.
The connection hinge 80 may include a first connection hinge 81 pivotably supporting the pressing body 62, and a second connection hinge 82 pivotably supporting the pressing body and disposed under the first connection hinge 81.
The pressing body 62 may further include a pressing plate 622 that is pivotably moved toward the support body 61, and a curved groove 621 that is recessed along the longitudinal direction of the pressing plate 622 so as to avoid a sewing line disposed in the laundry P or to concentrate an applied force onto both lateral ends of the laundry P.
Thus, the pressing body 62 may pivot toward the support body 61 to press the one face of the laundry P, and the support body 61 may press the other face of the laundry P due to an action/reaction to the pressing body.
In one example, the ironing presser 60 may further include an ironing partitioning portion 63 that is disposed between the support body 61 and the pressing body 62 and is pivotably moved toward the support body and the pressing body. Therefore, the door assembly 100 may further include the ironing partitioning portion 63 that is disposed between the support body 61 and the pressing body 62 and is pivotably moved toward the support body and the pressing body.
Specifically, the ironing partitioning portion 63 may include an ironing partitioning body 631 disposed between the support body 61 and the pressing body 62 and pivotably moved toward the support body and the pressing body. The ironing partitioning body 631 may have an area corresponding to an area of each of the pressing body 62 and the support body 61. Accordingly, all of laundry disposed between the pressing body 62 and the ironing partitioning body 631, and laundry disposed between the support body 61 and the ironing partitioning body 631 may be pressed.
The ironing partitioning body 631 may be pivotably coupled to the first connection hinge 81 and the second connection hinge 82 and may be configured to pivot separately from the pressing body 62, or may be configured to pivot integrally with the pressing body 62.
The ironing partitioning body 631 may be configured to pivot toward the support body 61 independently from the pressing body. Alternatively, when the pressing body 62 pivots toward the support body 61, the ironing partitioning body 631 may pivot together with the pressing body 62 toward the support body 61.
Referring to
For example, the first portion P1 and the second portion P2 of the laundry P may be held on a top or bottom of the ironing partitioning body 631, and the first portion P1 may be supported on one face of the ironing partitioning body 631 facing toward the pressing body 62 while the second portion P2 may be supported on the other face thereof facing toward the support body 61.
In this connection, the first portion P1 and the second portion P2 may be held on a top or bottom of the ironing partitioning body 631 in an overlapped manner. Thus, the first portion P1 and the second portion P2 of the laundry may be unfolded due to its own weight, and may not be placed in an overlapped manner. In this way, the first portion P1 and the second portion P2 of the laundry may be accurately pressed such that wrinkles may be removed therefrom or creases may be accurately formed in both lateral ends thereof.
In one example, a laundry holding member 632 protruding from both faces or one face of the ironing partitioning body 631 may be further included.
The laundry holding member 632 may prevent excessive contact of the laundry with the support body 61 and the pressing body 62. When the laundry P is pressed against the pressing body 62 or the ironing partitioning portion 63, the laundry holding member 632 may prevent the position of the laundry from changing.
To this end, the laundry holding member 632 may be made of a material having a higher friction than that of the ironing partitioning body 631, or having a shock absorbing ability.
The ironing partitioning portion 63 having a certain thickness and the laundry are disposed between the support body 61 and the pressing body 62. Thus, there is a concern that even when the pressing body 62 presses the laundry, the pressing body 62 may pivot in an opposite direction to a direction toward the support body 61 due to a reaction to the pressing.
Therefore, in order to prevent this situation, the laundry treating apparatus 1000 according to the present disclosure may further includes a coupling hook 613 disposed on the support body 61 to fix the pressing body thereto, and a hook coupler 623 disposed on the pressing body and coupled to the coupling hook.
In an example, the hook coupler 623 may include a hook protrusion 623 protruding from a lateral face of the pressing plate 622, and the coupling hook 613 may have a hook shape so as to be engaged with the hook protrusion 623.
Further, unlike shown in
Accordingly, when the pressing body 62 pivots toward the support body 61, the pressing body 62 presses one garment against the ironing partitioning body 631, and the ironing partitioning body 631 may press another garment against the support body 61.
Therefore, pressing all of the plurality of garments using one ironing presser 60 may allow removing wrinkles or forming the crease.
Furthermore, when the laundry is an upper garment, the garment contacts the outer circumferential face of the ironing partitioning body 631 and encloses the ironing partitioning body 631 therein. Thus, one face and the other face of the garment are simultaneously pressed against the pressing body 62 and the support body 61.
In one example, when the ironing partitioning portion 63 is provided between the support body 61 and the pressing body 62, moisture or hot-air supplied from the machine chamber 20 may not be supplied to the laundry therebetween. Therefore, the ironing presser 60 may require a separate component capable of supplying heat or steam to the laundry P.
In one example, the support body 61 may include a coupler 311 capable of detachably coupling the ironing partitioning body 631 thereto. The coupler 311 may be embodied in a hook manner such that a portion of an outer peripheral face of the ironing partitioning body 631 is inserted into the coupler, and may be configured such that a fastening portion disposed on the pressing body 62 may be simultaneously coupled to the coupler.
The heater 64 may be configured to effectively remove wrinkles or effectively generate creases by supplying heat energy to the laundry pressed between the ironing partitioning portion 63 and the support body 61 and to the laundry pressed between the pressing body 62 and the ironing partitioning portion 63.
The heater 64 may include a heating body 640 disposed on at least one of both faces of the ironing partitioning body 631 and exposed to the outside, and a heating wire 6320 disposed in one of the ironing partitioning body 631 and the heating body 631 to heat the heating body 640.
The heating body 640 may be made of a conductor or a metal material so as to transfer heat well, and the heating wire 6320 may be configured to transfer heat to the heating body 640 while being heated with electric energy or the like.
The heating body 640 may be detachably coupled to both faces of the ironing partitioning body 631 to form exposed faces of the ironing partitioning body 631. That is, a heating body coupled to one face closer to the inner face of the door assembly 100 among both faces of the ironing partitioning body 631 is a first heating body 6411, while a heating body disposed on the other face of the ironing partitioning body 631 is a second heating body 6412.
In another example, when the heating body and the fixing body are made of the same material, the heating body 640 may be formed integrally with the ironing partitioning body 631.
The heating wire 6320 may be attached to a rear face of the heating body 640. However, a configuration in which the heating wire 6320 is disposed on the ironing partitioning body 631 may be more advantageous for safety. In other words, the heating wire 6320 on the ironing partitioning body 631 may be configured to be spaced apart from the heating body 640 by a predetermined spacing to indirectly heat the heating body 640.
The heating wire 6320 may be configured to receive electrical energy from the cabinet 10 or the machine chamber 20 of the laundry treating apparatus 1000 according to the present disclosure, and may be connected to the outside of the ironing presser 60 via the first connection hinge 81 or the second connection hinge 82. The heating wire 6320 may be evenly installed on both sides of the ironing partitioning body 631 while extending in a reciprocating manner a plurality of times in a height direction and a width direction so as to evenly supply heat to one face of the heating body 640.
In one example, the heater 64 may include a supply channel 6310 that is defined in one of the ironing partitioning body 631 and the heating body 640 to supply steam, and a plurality of discharge holes 643 configured to pass through the heating body 640 and discharge the steam to the laundry.
Water may be supplied to the supply channel 6310, and may be heated by the heating wire 6320 and may be converted to the steam which in turn may be discharged to the discharge hole 643. Alternatively, the steam or mist may be directly supplied to the supply channel 6310.
The supply channel 6310 may include a plurality of channels which are arranged and spaced from each other by a predetermined spacing along a height direction or a width direction of the ironing partitioning body 631. The discharge hole 643 may include a plurality discharge holes which may be arranged along the extending direction of the supply channel 6310. Accordingly, steam may be evenly supplied to laundry P through the discharge hole 643.
The heater 64 may include only one of the supply channel 6310 and the heating wire 6320 or may include both the supply channel 6310 and the heating wire 6320.
In one example, when the heater 64 include both the supply channel 6310 and the heating wire 6320, the heating wire 6320 may be disposed outside the supply channel 6310 so as not to interfere with the supply channel 6310. Further, the heating wire 6320 may extend to surround the supply channel 6310.
Further, the ironing partitioning portion 63 is pivotably disposed in the first laundry treating chamber 11 or the door assembly 100. Thus, an installation area of a channel for supplying steam to the supply channel 6310 may be limited.
The supply channel 6310 may include a main channel 6312 defined in the ironing partitioning body 631 or disposed on a surface of the ironing partitioning body 631, a plurality of branched channels 6313 branched from the main channel 6312 in in the height direction or the width direction of the ironing partitioning body 631, and a plurality of spray channels 6314 extending in the same direction from the branched channel 6313 to supply steam to the laundry P.
In this connection, steam has lower density. Thus, each of the plurality of spray channels 6314 preferably extends in the height direction to facilitate movement of the steam. It is preferable that the spray channels 6314 are arranged and spaced apart from each other in the width direction so that steam may be sprayed onto a larger area.
Accordingly, when steam, moisture, or water is supplied only to the main channel 6312, the steam, moisture or water may be distributed along the spray channels 6314 so that steam may be evenly sprayed from the ironing partitioning body 631 to the laundry.
The supply channel 6310 may further include a communication channel 6311 configured to communicate with an auxiliary steam supply 85 disposed outside the ironing partitioning body 631 and to deliver water or steam to the main channel 6312.
In one example, the heating wire 6320 is configured to communicate with one of the first connection hinge 81 and the second connection hinge 82, while the main channel 6311 is configured to communicate with the other of the first connection hinge 81 and the second connection hinge 82, so that the heating wire and the main channel may not overlap each other.
To this end, passages 811 and 821 through or with which the heating wire or the main channel 6311 may pass or communicate may be defined in the first connection hinge 81 and the second connection hinge 82, respectively.
The auxiliary steam supply 85 may be disposed in an area easily accessible to a user of the cabinet, the machine chamber 20, the door, or the presser.
The auxiliary steam supply 85 may be disposed on at least one of the cabinet, the machine chamber 20, the door, and the presser. Because the laundry treating apparatus 1000 may not be connected to an external water supply source, the auxiliary steam supply 85 is preferably disposed detachably on at least one of the cabinet, the machine chamber 20, the door, and the presser.
Further, because the auxiliary steam supply 85 is advantageously disposed in a region closest to the supply channel 6310, it is preferable that the auxiliary steam supply 85 is disposed on the ironing partitioning portion 63. Alternatively, because the pressing body 62 is first exposed to the user, it is preferable that the auxiliary steam supply 85 is disposed on the pressing body 62.
When the auxiliary steam supply 85 is detachably installed on the pressing body 62, the pressing body 62 may further include a connection channel 6221 configured to communicate the auxiliary steam supply 85 with the connection hinge 80.
The connection channel 6221 has a tubular shape. The moisture or steam supplied from the auxiliary steam supply 85 thereto may be discharged from the connection channel 6221. The connection channel 6221 may be defined in the pressing body 62.
Thus, the connection channel 6221 and the communication channel 6311 may communicate with each other through the second connection hinge 82, so that moisture or steam generated from the auxiliary steam supply 85 may be completely discharged to the discharge hole 643.
In one example, the supply channel 6310 defined in the ironing partitioning body 631. The ironing partitioning body 631 may have a plurality of through holes configured to communicate with the discharge holes 643 of the heater 64.
Thus, the supply channel 6310 is not disposed on each of both faces of the ironing partitioning body 631, but is defined inside the ironing partitioning body 631, a thickness of the ironing partitioning body 631 may be reduced. Further, there is an advantage that steam may be supplied to both faces of the ironing partitioning body 631 through one supply channel 6310.
The auxiliary water tank 850 may have a case shape having a certain volume, and may have an open top face so as to easily receive water or to facilitate cleaning. The auxiliary water tank 850 may further include a cover 853 configured to shield the top open face.
Further, the auxiliary water tank 850 ma have a heater receiving hole 811 defined in a side face thereof into which the auxiliary heater 854 is inserted in a fixed manner. The auxiliary heater 854 may be configured to be inserted into the heater receiving hole 811 in a fixed manner to heat water accommodated in the auxiliary water tank 850 to generate the steam.
The discharge hole 852 may be defined at a top of one side face of the auxiliary water tank 850 so that the steam having a relatively low density may be completely discharged therethrough. The discharge hole 852 may be configured to communicate with the connection channel 6221.
The pressing body 62 may further have a tank receiving space 623 defined therein configured to accommodate the auxiliary water tank 850 therein. Further, when the auxiliary water tank 850 is received in the tank receiving space 623, an exposed face of the auxiliary water tank 850 and one face of the pressing body 62 may constitute the same face.
Accordingly, when water is supplied to the auxiliary water tank 850, steam may be supplied to the laundry P through the heater 64.
In one example, unlike shown in the drawing, the heater 64 may be configured to communicate with the machine chamber 20 or the auxiliary water tank 850 to receive hot-air or moisture directly therefrom, and to discharge the hot-air or moisture toward the pressing body 62 and the support body 61.
In other words, the heater 64 may be formed integrally with the ironing partitioning body 631 and may have the discharge hole 643 for discharging the hot-air and moisture.
Each of the first connection hinge 81 and the second connection hinge 82 may have a channel communication with the machine chamber 20. The ironing partitioning body 631 may have a supply channel defined therein communicating with the channel defined in each hinge to supply hot-air or moisture to the heater 64.
The heater 64 communicates with the machine chamber 20. In this case, when the hot-air or moisture from the machine chamber 20 is supplied to the receiving space 14, the hot-air or moisture from the machine chamber 20 may be supplied to the heater 64.
Alternatively, the steam generator 41 of the machine chamber 20 may be configured to communicate with the ironing partitioning portion 63 and supply steam thereto.
That is, as in
Accordingly, the steam generated from the steam generator 41 may be directly delivered to the ironing partitioning portion 63 which may supply the steam to the laundry P. In this case, the heating wire 6320 and the auxiliary steam supply 85 may be omitted.
The laundry treating apparatus 1000 according to the present disclosure may further include a laundry hanger 90 disposed above and/or under the ironing presser 60 to hold or fix the laundry thereon or thereto. A position of the laundry hanger 90 may be defined relative to the support body 61, the pressing body 62, and the ironing partitioning portion 63. That is, the laundry hanger 90 may be disposed above and/or under one of the support body 61, the pressing body 62, and the ironing partitioning portion 63.
The laundry hanger 90 may include hanger bodies 911 and 921 disposed above and/or under the presser to support the laundry thereon, and fixing bodies 912 and 922 that are respectively coupled to the hanger bodies to fix the laundry to the hanger bodies.
Each of the hanger bodies 911 and 921 may maintain the laundry P in a fully stretched state to prevent the laundry from being wrinkled or being displaced when the laundry is pressed against the presser 60.
In this connection, when the laundry hanger 90 is in a fixed state while the partitioning portion 63 is pivoting, the laundry may be damaged. Thus, the hanger bodies 911 and 921 may be configured to pivot together with the pivoting of the partitioning portion 63.
Further, the fixing bodies 912 and 922 may be pivotably coupled to the hanger bodies 911 and 921 respectively, so that the laundry is fitted between each of the fixing bodies 912 and 922 and each of the hanger bodies 911 and 921 in a fixed manner.
Each of the hanger bodies 911 and 921 may be coupled to each of the fixing bodies 912 and 922 in a hook coupling manner, thereby to prevent the laundry P from being removed therefrom. For example, each of the hanger body 911 and 921 may have a hook coupler 9112, while each of the fixing bodies 912 and 922 may have a coupling hook 9122 to which a corresponding coupling hook is coupled.
In one example, the laundry hanger 90 may be installed only above the ironing presser 60 to fix the laundry P thereto, so that the laundry P may be in a fully stretched manner via its own weight.
However, when the ironing presser 60 applies a relatively large force for pressing the laundry P, or when pressing in a direction from one side of the laundry P to the other side thereof, the position of the laundry P may be changed or the laundry P may be wrinkled.
Thus, the laundry hangers 90 may be respectively disposed above and under the ironing presser 60 to apply sufficient tension to the laundry P, thereby preventing the laundry P from being wrinkled or displaced.
Referring to
The first laundry hanger 91 and the second laundry hanger 92 may be configured to pivot together with the ironing partitioning portion 63.
The first laundry hanger 91 may include a first hanger body 911 pivotably disposed above the ironing partitioning portion 63 and a first fixing body 912 pivotably coupled to the first hanger body 912 to fix the laundry to the first hanger body.
The first hanger body 911 may be embodied as a plate having a length larger than a width thereof. The first fixing body 912 may be pivotably coupled to the first hanger body 911, but a free end thereof may be configured to be detachably coupled to the first hanger body 911.
The first hanger body 911 may further have a receiving groove 9111 to accommodate the laundry therein. One face of the groove 9111 may be curved. Therefore, the laundry may be prevented from being excessively pressed.
In one example, the second laundry hanger 92 may include a second hanger body 921 pivotably disposed under the ironing partitioning portion 63, and a second fixing body 922 that is pivotably coupled to the second hanger body to fix the laundry to the second hanger body.
The second hanger body 921 may have a first through-slit 9214 defined therein through which a first portion of the laundry P passes. The second fixing body 922 may have a second through-slit 9223 defined therein through which a second portion of the laundry passes.
Accordingly, the first portion P1 and the second portion P2 of the laundry may be inserted into the first through-slit and the second through-slit respectively and may be guided along both side faces of the partitioning portion 63 respectively in a divided manner.
Therefore, referring to
Further, the first portion P1 and the second portion P2 of the laundry may overlap each other in a region above the ironing presser 60 and may be inserted between the first hanger body 911 and the first fixing body 912 in a fixed manner.
In this connection, the first portion P1 of the laundry, and the second portion P2 may be inserted between the first hanger body 911 and the first fixing body 912 in a fixed manner while being in a fully stretched tight state.
Unlike shown in the drawing, the first laundry hanger 91 may have a through-slit defined therein. The second laundry hanger 92 may have a laundry receiving groove defined therein. Accordingly, the user may adjust the hanging direction of laundry P as necessary.
Referring to
Referring to
Then, the user may overlap the free ends of the first portion P1 and the second portion P2 of the laundry P each other and may pull the free ends upwardly such that the laundry is in a fully stretched tight state. In this state, the first portion P1 and the second portion P2 of the laundry P in the overlapped sate may be fixed to the first hanger body 911 and the second fixing body 921 in the fully stretched tight state.
Referring to
Referring to
Thus, both the first portion P1 and the second portion P2 of the laundry P are pressed against the ironing partitioning portion 63. In this connection, when heat and steam are supplied from the heater 64 to the laundry, wrinkles are removed from the first portion P1 and the second portion P2 of the laundry P and the crease is formed in the first portion P1 and the second portion P2 of the laundry P.
The first base plate 114, the first ironing partitioning portion 6301, the partitioning portion 160, the second ironing partitioning portion 6302 and the second base plate 134 disposed on the inner face 111 of the first panel are pivotably coupled to each other at one side thereof via the connection hinge 80. That is, the connection hinge 80 may be disposed on the first base plate 114, and may be disposed on the inner face 111 of the first panel 110 on which the 1 base plate 114 is disposed.
Further, the connection hinge 80 may include the first connection hinge 81 disposed on the top of the first base plate to pivotably retain the first ironing partitioning portion 6301, the partitioning portion 160, the second ironing partitioning portion 6302 and the second base plate 134, and the second connection hinge 82 disposed on the bottom of the first base plate to pivotably retain the first ironing partitioning portion 6301, the partitioning portion 160, the second ironing partitioning portion 6302, and the second base plate 134.
The second base plate 134 may be fixed to the second panel 130 and thus may be coupled to the second ironing partitioning portion 6302 and the partitioning portion when the second panel pivots. In this case, the connection hinge 80 pivotably retains only the first base plate 114, the first ironing partitioning portion 6301, the partitioning portion 160, and the second ironing partitioning portion 6302.
In this case, as in
Alternatively, the steam generator 41 of the machine chamber 20 may be configured to communicate with the ironing partitioning portion 63 to supply steam thereto.
That is, as in
Accordingly, the steam generated from the steam generator 41 may be directly delivered to the ironing partitioning portion 63 which in turn may supply the steam to the laundry P. In this connection, the heating wire 6320 and the auxiliary steam supply 85 may be omitted.
In order to hold the laundry held on the first ironing partitioning portion 6301 and the laundry held on the second ironing partitioning portion 6302, the laundry hanger may include a first right hanger body 91101 and a first right fixing body 91201 disposed above the first ironing partitioning portion 6301; a first left hanger body 91202 and a first left fixing body 91202 disposed above the second ironing partitioning portion 6302; a second right hanger body 92101 and a second right fixing body 92201 disposed below the first ironing partitioning portion 6301; and a second left hanger body 92102 and a second left fixing body 92202 disposed below the second ironing partitioning portion 6302. This configuration is intended to hold the laundry held on the first ironing partitioning portion 6301 and the laundry held on the second ironing partitioning portion 6302, respectively. Detailed descriptions of this embodiment other than the above description of the intended configuration are the same as the descriptions based on
Referring to
The laundry treating apparatus 1000 according to this embodiment includes the first panel 110 which is pivotably connected to the cabinet 10, the second panel 130 pivotably connected to the first panel 110, and the partitioning plate 160 that is disposed between the first panel 110 and the second panel 130 and press laundry disposed on each of both side faces thereof. Further, the first ironing partitioning portion 6301 and the second ironing partitioning portion 6302 are disposed between the first panel 110 and the partitioning plate 160, and between the partitioning plate 160 and the second panel 130, respectively.
The first panel 110 according to this embodiment opens and closes the open front face of the cabinet 10. The second panel 130 according to this embodiment is disposed in front (F) of the first panel 110.
The door assembly 100 according to the present embodiment may open and close only the second panel 103 while the door assembly 100 closes the cabinet 10. Therefore, even when the laundry is being treated in the first laundry treating chamber 11, the second laundry treating chamber 12 may be opened to treat laundry such as pants therein via pressurization.
