Because the introduced air has already passed through the inside of the tub 20, the introduced air may be high-temperature and humid. The high-temperature and humid air may be cooled in the evaporator 73 disposed in the heating flow path 77 to remove moisture. Afterwards, the air may be heated again while passing through the condenser 72.
The supply flow path 78 may supply the air, heated while passing through the condenser 72, back to the tub 20. The supply flow path 78 may communicate with the heating flow path 77 and extend downward to discharge the heated air toward an air inlet 26 of the tub 20.
The supply flow path 78 may include a blower fan 78a to allow air to flow into the tub 20. According to an embodiment, the blower fan 78a may be disposed in the supply flow path 78. The blower fan 78a may cause air from the heating flow path 77 and the supply flow path 78 to flow into the drum 30. For example, the blower fan 78a may include a sirocco fan.
In the clothes care apparatus 1 according to an embodiment, the supply flow path 78 may be formed to allow air to move downward from below the blower fan 78a disposed at the front of the drying base 70b. The supply flow path 78 may extend downward from the blower fan 78a and connect the blower fan 78a and the air inlet 26 of the tub 20. The supply flow path 78 extends below the blower fan 78a, thereby minimizing/reducing the front-to-back volume. In other words, the volume of the clothes care apparatus 1 in the front-back direction due to the supply flow path 78 may be prevented or minimized and/or reduced from being increased.
With the above configuration, the air that has passed through the heating flow path 77 may be introduced into the supply flow path 78 by the blower fan 78a, move along the supply flow path 78 downwardly to the blower fan 78a, and then may be discharged into the tub 20 through the air inlet 26.

Referring to
An opening 24a may be formed at one end of the duct portion 24. The opening 24a may refer to the air inlet 26 described above. An outlet 78c may be formed at one end of the supply duct 78b forming the supply flow path 78. The opening 24a and the outlet 78c may be of corresponding sizes and shapes. When the duct portion 24 and the supply duct 78b are connected, the opening 24a and the outlet 78c may be substantially the same hole. When the duct portion 24 and the supply duct 78b are connected, the opening 24a and the outlet 78c may each be the air inlet 26.
The clothes care apparatus 1 may include the exhaust flow path P to allow the air discharged from the inside of the tub 20 to flow to the drying device 70. The air that has passed through the exhaust flow path P may flow into the inlet flow path 76 of the drying device 70. For example, the exhaust flow path P may be provided at the rear of the tub 20.
The air may circulate through the inside of the tub 20 and the drying device 70 by the exhaust flow path P, the inlet flow path 76, the heating flow path 77, and the supply flow path 78.
In the clothes care apparatus 1 according to an embodiment of the disclosure, the air discharged to the rear of the tub 20 may flow into the inlet flow path 76 of the drying device 70, located above the tub 20, through the exhaust flow path P, then sequentially pass through the heating flow path 77 and the supply flow path 78, and then be supplied back into the inside of the tub 20.
A tub exhaust port 220 may be formed in the tub back 200 to allow the air in the tub 20 to be discharged to the rear of the tub 20. The air discharged through the tub exhaust port 220 may flow into the inlet flow path 76 along the exhaust flow path P.
In the clothes care apparatus 1 according to an embodiment, the exhaust flow path P may be formed by coupling a duct cover 100 to the tub back 200. The exhaust flow path P may be formed by coupling the duct cover 100 to a tub duct 213, which will be described later.
The tub back 200 according to an embodiment may include reinforcing ribs 201 (see, e.g.,
The reinforcing ribs 201 may be formed to reinforce a rigidity of the tub back 200. The reinforcing ribs 201 may protrude rearward from the rear surface of the tub back 200.
The tub duct 213 may include a recess portion 210 and a partition rib 230. The recess portion 210 may be formed around the tub exhaust port 220, and may refer to a portion where the reinforcing ribs 201 are not formed or a portion that is recessed forward than rear ends of the reinforcing ribs 201. The recess portion 210 may be formed to have a narrower front and rear width than a portion where the reinforcing ribs 201 are formed in the tub back 200. That is, the front and rear width of the recess portion 210 may be smaller than the front and rear width of the portion where the reinforcing ribs 201 are formed. Accordingly, the recess portion 210 may be recessed from the tub back 200. In other words, the recess portion 210 may be formed such that a portion of the tub back 200 is formed in a stepped manner. In addition, a portion of the rear surface of the tub back 200 where the reinforcing ribs 201 are not formed may be referred to as the recess portion 210. The partition rib 230 may refer to a protrusion formed along an edge of the recess portion 210. The partition rib 230 may protrude from the edge of the recess portion 210 to the rear of the tub back 200. The partition rib 230 may form a side wall of the exhaust flow path P. A front-to-back width of the partition rib 230 may be greater than or equal to that of the reinforcing rib 201. The front-to-back width of the partition rib 230 may be referred to as a height of the partition rib 230. The front-to-back width of the reinforcing rib 201 may be referred to as a height of the reinforcing rib 201.
The air heated in the drying device 70 may flow into the tub 20, and then be supplied into the drum 30. In this instance, an area where the heated air supplied into the drum 30 comes into contact with the laundry is required to be secured. The longer the distance and time for which the heated air flows in the drum 30, the more the heated air may come into contact with the laundry. Accordingly, the tub exhaust port 220 may be formed at a position opposite to the air inlet 26 through which the air heated in the drying device 70 flows into the tub 20.
The air inlet 26 through which the air heated in the drying device 70 flows into the tub 20 and the tub exhaust port 220 through which the air in the tub 20 is discharged may be located as far apart as possible. To this end, the air inlet 26 and the tub exhaust port 220 may be located diagonally when the tub 20 is viewed from the front or rear.
For example, in a case where the air inlet 26 is formed at an upper right front side of the tub 20 or at a position adjacent to the upper right front side of the tub 20, the tub exhaust port 220 may be formed at a lower left side of the tub back 200, or at a position adjacent to the lower left side of the tub back 200. In this case, the heated air moves from the front upper right side of the tub 20 toward the lower left side of the tub back 200, and thus the heated air may move in a similar direction inside the drum 30 disposed in the tub 20. That is, the heated air may move diagonally from the upper right front side of the drum 30 toward the lower left rear side of the drum 30. As a result, a movement path of the heated air in the drum 30 may be as long as possible. As the movement path of the heated air increases, the heated air may come into contact with the laundry in the drum 30 over a large area for a long time, and thus a drying efficiency of the clothes care apparatus 1 may be improved.
However, the disclosure is not limited thereto, and the air inlet 26 and the tub exhaust port 220 may be arranged in different positions depending on an area of each of the air inlet 26 and the tub exhaust port 220 and/or an air volume of the blower fan 78a.
The exhaust flow path P may be formed by the duct cover 100 covering one open side of the recess portion 210. The exhaust flow path P may be a single flow path formed by the recess portion 210 and the duct cover 100 together.
The duct cover 100 may be coupled to the tub back 200. The duct cover 100 may form the exhaust flow path P through which the air discharged through the tub exhaust port 220 flows to the drying device 70. Specifically, the duct cover 100 may be coupled to cover the one open side of the recess portion 210 formed in the tub back 200. A method of coupling the duct cover 100 to the tub back 200 will be described later.
The tub 20 may include a duct connection portion 270 protruding outwardly from the tub body 22a in a radial direction of the tub body 22a. For example, the duct connection portion 270 may protrude upward from a rear end of the tub body 22a. However, the disclosure is not limited thereto, and the duct connection portion 270 may be positioned in various manners depending on the location of the drying device 70.
The duct connection portion 270 may connect the inlet guide 76a of the drying device 70 and the tub duct 213. The duct connection portion 270 may form a portion of the exhaust flow path P together with the recess portion 210, the partition rib 230, and the duct cover 100.
The duct cover 100 may cover the tub duct 213 and the duct connection portion 270. The duct cover 100 may cover both an open side of the tub duct 213 and an open rear side of the duct connection portion 270. The duct cover 100 covers the recess portion 210 and the duct connection portion 270, thereby forming the exhaust flow path P. Because the exhaust flow path P is connected to the inlet flow path 76, the air flowing into the exhaust flow path P through the tub exhaust port 220, formed in the tub back 200, may move upward along the exhaust flow path P, and may flow into the drying device 70 through the inlet flow path 76.
Although not illustrated, the duct connection portion 270 may be provided in a rectangular parallelepiped shape with only an upper surface through which air is discharged open and the rear surface closed. In this case, the duct cover 100 may cover only the tub duct 213.
Referring to
A tub through hole 240 through which the rotating shaft 41 passes may be provided in the center of the tub back 200. The tub exhaust port 220 to which the exhaust flow path P is connected may be formed on one lower side of the tub back 200.
The heated air supplied into the tub 20 through the supply flow path 78 may flow into the drum 30, absorb moisture from the laundry in the drum 30, become humid air, and be discharged from the drum 30 and the tub 20. In the above process, the heated air is required to be spread throughout the drum 30 so as to sufficiently remove the moisture in the laundry and improve a drying efficiency. To this end, a flow path connecting from the front to the rear of the drum 30 is required to be secured, and a flow path is required to reduce the amount of heated air discharged through the plurality of through holes 32a formed in the cylindrical drum body 32, before the heated air reaches the rear of the drum 30. According to the disclosure, the tub exhaust port 220 may be formed in the tub back 200 to increase the amount of heated air discharged to the rear of the drum 30.
By the tub exhaust port 220 formed in the tub back 200, the heated air supplied to the air inlet 26 of the tub 20 may be discharged out of the tub 20 through the tub exhaust port 220. In order to move the humid air discharged from the tub 20 back to the drying device 70, a flow path connecting the tub back 200 and the drying device 70 is required. According to an embodiment, the exhaust flow path P may be provided to move the humid air discharged from the tub 20 back to the drying device 70.
Meanwhile, the bearing housing 51 is mounted on the tub back 200, and the tub back 200 is required to have sufficient rigidity to withstand the pressure and load caused by the water stored in the tub 20. To this end, the plurality of reinforcing ribs 201 may be formed on the tub back 200. Because the reinforcing ribs 201 protrude rearward from the rear surface of the tub back 200, a front-to-back thickness of the tub back 200 increases by a length over which the reinforcing ribs 201 protrude. In the above-described structure, in order to mount a separate duct on the reinforcing ribs 201 of the tub back 200, a capacity of the housing 10 is required to be secured as much as the size of the duct. In other words, an internal space of the housing 10 is required to be increased in the front-to-back direction by the front-to-back thickness of the duct separately mounted on the tub back 200.
According to the disclosure, the reinforcing ribs 201 may not be formed on a portion of the tub back 200 to allow the portion of the tub back 200 to be used as a flow path. When a length from the front surface of the tub back 200 to the rear ends of the reinforcing ribs 201 is considered a thickness of the tub back 200, a portion of the tub back 200 may be viewed as being recessed. In the disclosure, the recess portion 210 formed in the tub back 200 may refer to an area which extends from the tub exhaust port 220 of the tub back 200 to an upper portion of the tub back 200 and in which the reinforcing ribs 201 are not formed, or an area that protrudes less than the reinforcing ribs 201.
The plurality of reinforcing ribs 201 may be formed at the rear of the tub back 200. The plurality of reinforcing ribs 201 may include annular reinforcing ribs 201a and radial reinforcing ribs 201b. The annular ribs 201a may have different radii centered on the tub through hole 240.
The radial reinforcing ribs 201b may extend in a radial direction from the tub through hole 240. In addition, the radial reinforcing ribs 201b may extend through the annular reinforcing ribs 201a. The plurality of reinforcing ribs 201 may reinforce a rigidity of the tub back 200. The plurality of reinforcing ribs 201 may include the annular reinforcing ribs 201a having the same center as a center C of the tub through hole 240. The annular reinforcing ribs 201a may have different radii. The plurality of reinforcing ribs 201 may include the radial reinforcing ribs 201b extending in a radial direction from the tub through hole 240. The radial reinforcing ribs 201b may extend through the annular reinforcing ribs 201a.
The tub back 200 may include the partition rib 230 protruding to the rear of the tub back 200 to partition a portion of the tub back 200 in which the recess portion 210 is formed from a remaining portion of the tub back 200. The partition rib 230 may be formed to surround the recess portion 210. The partition rib 230 may be formed along an edge of the duct connection portion 270 as well as an edge of the recess portion 210.
A height of the partition rib 230 may be higher than that of the plurality of reinforcing ribs 201. The height of the partition rib 230 higher than the height of the plurality of reinforcing ribs 201 may refer to the partition rib 230 protruding more toward the rear of the tub back 200 than the plurality of reinforcing ribs 201 protruding toward the rear of the tub back 200. In other words, the partition rib 230 may protrude more toward the rear of the tub back 200 than the plurality of reinforcing ribs 201.
The partition rib 230 may include an outer partition rib 231, an inner partition rib 232, and a connection partition rib 233.
The outer partition rib 231 may be disposed on one side of the tub exhaust port 220 in a radial direction of the tub back 200. The inner partition rib 232 may be disposed on another side of the tub exhaust port 220 in the radial direction of the tub back 200. The connection partition rib 233 may connect the outer partition rib 231 and the inner partition rib 232. The outer partition rib 231 may be disposed further from the tub through hole 240 in the radial direction of the tub back 200 than the inner partition rib 232. Accordingly, the one side of the tub exhaust port 220 may be referred to as an outer side of the tub exhaust port 220, and the other side of the tub exhaust port 220 may be referred to as an inner side of the tub exhaust port 220.
The inner partition rib 232 may extend from the annular reinforcing rib 201a to form a circular rib together with the annular reinforcing rib 201a. The outer partition rib 231 may be formed along an edge of the disk-shaped tub back 200. The outer partition rib 231 may protrude rearward from a rear edge of the tub back 200. As described above, the inner partition rib 232 may protrude more rearwardly than the annular reinforcing rib 201a that forms a circular rib together with the inner partition rib 232. The outer partition rib 231 may protrude toward the rear of the tub back 200 to allow a rear end of the outer partition rib 231 to be located on the same plane as a rear end of the inner partition rib 232.
The tub back 200 may include a plurality of tap holes 2121 spaced apart from each other along the partition rib 230. The plurality of tap holes 2121 may be formed outside the recess portion 210. The plurality of tap holes 2121 may be formed adjacent to each of the outer partition rib 231, the inner partition rib 232, and the connection partition rib 233.
The duct cover 100 may be coupled to the plurality of tap holes 2121. The plurality of tap holes 2121 may be spaced apart from each other by a predetermined distance. The plurality of tap holes 2121 may be formed through tapping for fastening screws. However, the disclosure is not limited thereto, and a hole for fastening a rivet, or the like, may be formed.
Referring to
A plurality of tub exhaust ports 220 may be formed. The plurality of tub exhaust ports 220 may be spaced apart from each other. The plurality of tub exhaust ports 220 may be spaced apart from each other along the recess portion 210.
The tub exhaust ports 220 may include a first tub exhaust port 221 formed on a lower side of the recess portion 210, a second tub exhaust port 222 formed above the first tub exhaust port 221, and a third tub exhaust port 223 formed above the second tub exhaust port 222.
The first tub exhaust port 221 may be formed on the lower side of the recess portion 210. The first tub exhaust port 221 may include a drain groove 221a to allow wash water to drain into the tub 20 without remaining. The drain groove 221a may be inclined toward the inside of the tub 20.
The second tub exhaust port 222 may be formed above the first tub exhaust port 221. The second tub exhaust port 222 and the first tub exhaust port 221 are arranged to have a gap therebetween, and thus a rigidity of the tub back 200 may be prevented/reduced from decreasing than in a case where the second tub exhaust port 222 and the first tub exhaust port 221 are formed integrally, and an air flow rate may be ensured.
The third tub exhaust port 223 may be formed above the second tub exhaust port 222. Likewise, a decrease in the rigidity of the tub back 200 may be prevented/reduced and the air flow rate may be secured.
In addition, the first tub exhaust port 221 and the second tub exhaust port 222 may be disposed below a horizontal line passing through the center C of the tub through hole 240 of the tub back 200. That is, a penetration area of a lower side of the tub exhaust port 220 may be formed to be larger than a penetration area of an upper side of the tub exhaust port 220 based on a center line of the tub through hole 240.
As described above, the drying device 70 is disposed above the tub 20, and thus the inlet flow path 76 and the supply flow path 78 may extend above the upper side of the tub 20. Accordingly, in order for the air discharged through the supply flow path 78 to effectively contact the laundry in the drum 30, a larger penetration area of the tub exhaust port 220 is required to be formed on the lower side than above the recess portion 210.
That is, in a case where a large penetration area of the tub exhaust port 220 is formed on the upper side than the lower side of the recess portion 210, the air circulating through the drying device 70 may be concentrated on an upper portion of the drum 30. That is, the drying efficiency of laundry accommodated in the drum 30 may be reduced.
However, in order to secure a sufficient flow rate, the tub exhaust port 220 may include an area formed above the center of the tub back 200. For example, the tub exhaust port 220 may include the third tub exhaust port 223 formed above the center of the tub back 200.
In addition, a distance between the first tub exhaust port 221, the second tub exhaust port 222, and the third tub exhaust port 223 may be set as a distance that may maintain a structural rigidity of the tub 20 and the tub back 200, while the second tub exhaust port 222 and the third tub exhaust port 223 are arranged as adjacent as possible to the first tub exhaust port 221. In addition, the distance may be set as a theoretically calculated value or as an experimental value obtained through repeated experiments.
Although the three tub exhaust ports 220 are illustrated in the drawings, the disclosure is not limited thereto. The shape and the number of tub exhaust ports 220 may vary. For example, the tub exhaust ports 220 may be small holes densely arranged, or may have a mesh or grille shape.
The tub 20 may be formed of a plastic material. The bearing housing 51 may be inserted into the tub back 200. That is, when injection molding the tub 20, the tub 20 may be injected with the bearing housing 51 inserted.
Referring to
The bearing housing 51 may be inserted into the tub back 200 to reinforce the rigidity of the tub back 200. For example, a recess reinforcement portion 511 of the bearing housing 51 may reinforce a rigidity of the recess portion 210 of the tub back 200.
The tub through hole 240 through which the rotating shaft 41 of the drive motor 42 passes may be formed in the tub back 200. The bearing 52 may be inserted into the tub through hole 240, and may rotatably support the rotating shaft 41.
The load caused by the water and laundry accommodated in the drum 30 is transmitted to the tub back 200 in which the tub through hole 240 is formed, through the rotating shaft 41 and the bearing 52. Because a rigidity of the tub back 200 is weak to support the load, the bearing housing 51 may be provided in the tub back 200.
The bearing housing 51 according to an embodiment may be in a disk shape having substantially the same diameter as the disk-shaped tub back 200.
In general, the bearing housing 51 may have a size smaller than the diameter of the tub back 200. However, the bearing housing 51 according to the disclosure may have a diameter that is equal to or similar to that of the tub back 200.
As described above, the tub exhaust port 220 may be formed in the tub back 200 to discharge the air in the tub 20, and the recess portion 210 forming the tub duct 213 may be formed around the tub exhaust port 220 for a smooth air flow. However, due to the tub exhaust port 220, formed through the tub back 200, and the recess portion 210 in which the reinforcing ribs 201 are not formed as a surrounding of the tub exhaust port 220, the rigidity of the tub back 200 may be reduced. To reinforce the rigidity of the tub back 200, the bearing housing 51 according to an embodiment may be provided to have a diameter and shape of substantially the same size as the tub back 200.
Air is required to be discharged through the tub exhaust port 220 located in the recess portion 210. The tub back 200 may include the tub exhaust port 220 formed to discharge air in the tub 20. In addition, the bearing housing 51 may include a housing exhaust port 520.
The housing exhaust port 520 may be formed to correspond to the tub exhaust port 220. In a case where a plurality of tub exhaust ports 220 are formed, a plurality of housing exhaust ports 520 may also be formed. That is, when the tub back 200 is injection molded, the bearing housing 51 may be inserted into the tub back 200 to allow the housing exhaust port 520 and the tub exhaust port 220 to overlap in position.
The housing exhaust port 520 may include a first housing exhaust port 521 corresponding to the first tub exhaust port 221. The first housing exhaust port 521 may be formed below the recess reinforcement portion 511.
The first housing exhaust port 521 may include a housing drain groove 521a formed to correspond to the drain groove 221a formed in the first tub exhaust port 221. Like the drain groove 221a, the housing drain groove 521a may be inclined toward the inside of the tub 20.
The housing exhaust port 520 may include a second housing exhaust port 522 corresponding to the second tub exhaust port 222 and a third housing exhaust port 523 corresponding to the third tub exhaust port 223.
The second housing exhaust port 522 may be formed above the first housing exhaust port 521. In addition, the third housing exhaust port 523 may be formed above the second housing exhaust port 522.
Likewise, the recess reinforcement portion 511 of the bearing housing 51 may be formed to correspond to the recess portion 210 of the tub back 200. When the tub back 200 is injection molded, the bearing housing 51 may be inserted to allow the recess reinforcement portion 511 and the recess portion 210 to overlap in position.
The tub back 200 may include a step portion 211 to expand a cross-sectional area of the exhaust flow path P. The step portion 211 may be formed by a portion of the recess portion 210 being stepped forward from a remaining portion of the recess portion 210.
The recess portion 210 and a front end of the duct connection portion 270 may be formed to be spaced apart in the front-back direction. In other words, the front end of the duct connection portion 270 forming a portion of the exhaust flow path P may be located ahead of the recess portion 210. The step portion 211 may extend obliquely from the recess portion 210 toward the duct connection portion 270 to connect the recess portion 210 and the front end of the duct connection portion 270. The step portion 211 may be formed to facilitate the air flow on a downstream side of the exhaust flow path P connected to the inlet flow path 76.
The bearing housing 51 may include an avoidance portion 311 corresponding to the step portion 211. Because the bearing housing 51 is not easily inserted into a portion recessed more than the recess portion 210, the avoidance portion 311 may be formed to avoid the above. The avoidance portion 311 may be formed in a portion of the recess reinforcement portion 310 corresponding to the step portion 211. The avoidance portion 311 may refer to a groove or hole having a shape corresponding to the step portion 211. Because the avoidance portion 311 is a groove or a hole of a shape corresponding to the step portion 211, the bearing housing 51 may not be inserted into the inside of the step portion 211. That is, the bearing housing may not be formed in an area corresponding to the step portion 211 of the tub back 200. The bearing housing 51 may include an avoidance portion 510a corresponding to the step portion 211. Because the bearing housing 51 is not easily inserted into a portion recessed more than the recess portion 210, the avoidance portion 510a may be formed to avoid the above. The avoidance portion 510a may be formed in a portion of the recess reinforcement portion 511 corresponding to the step portion 211.
The recess portion 210 and the duct connection portion 270 may be formed in a stepped manner. The step portion 211 may be formed by recessing a portion of the recess portion 210 adjacent to the duct connection portion 270. The flow rate may be reduced due to a step formed between the step portion 211 and the duct connection portion 270 in the exhaust flow path P. Accordingly, the step portion 211 may be formed to secure the flow rate of air flowing into the duct connection portion 270.
The bearing housing 51 may include a plurality of housing ribs 510 corresponding to the plurality of ribs 201 formed in the tub back 200. The plurality of housing ribs 510 may be formed to correspond to the plurality of ribs 201 formed in the tub back 200.
The plurality of housing ribs 510 may be formed to correspond to the annular reinforcing ribs 201a and the radial reinforcing ribs 201b including the plurality of ribs 201. The plurality of ribs 201 are not formed in the portion forming the recess portion 210 of the tub back 200, and also in the bearing housing 51, the plurality of housing ribs 510 may not be formed in the recess reinforcement portion 511.
The duct cover 100 may be coupled to the tub back 200. The duct cover 100 may be coupled to cover the recessed portion 210 of the tub back 200.
The duct cover 100 may include a cover portion 120 formed to correspond to the recess portion 210 so as to cover the recess portion 210. The duct cover 100 may include a connection portion 130 that is bent from a fastening flange portion 110 and connects the cover portion 120 and the fastening flange portion 110.
The cover portion 120 may protrude outwardly than the fastening flange portion 110. When the duct cover 100 is coupled to the tub 20, the cover portion 120 may protrude in a direction away from the recess portion 210.
The connection portion 130 may extend outwardly to allow the cover portion 120 to protrude from the fastening flange portion 110. In other words, when the duct cover 100 is positioned to cover the recess portion 210, the connection portion 130 extends rearward, and thus the cover portion 120 extends rearward.
Although not illustrated, the duct cover 100 may be formed in a plate shape in which the cover portion 120 and the fastening flange portion 110 are integrally formed. A shape of the duct cover 100 is not limited as long as the duct cover 100 may cover the recess portion 210.
Although it is illustrated that the duct cover 100 is fastened to the tub back 200 by screws, a connection method is not limited thereto. For example, the duct cover 100 may be coupled without a separate fastening means such as a snapfit or latch.
The duct cover 100 may include a material having higher rigidity than a material forming the tub 20. For example, the duct cover 100 may be formed of Aluminum Die Casting (ALDC) or stainless steel, like the bearing housing 51. However, the disclosure is not limited thereto, and the duct cover 100 is sufficient as long as it has a higher rigidity than the material forming the tub 20.
The duct cover 100 may include the fastening flange portion 110 in which a fastening hole 110a is formed. The fastening flange portion 110 may be provided with a plurality of fastening holes 110a. The plurality of fastening holes 110a may be spaced apart from each other along the fastening flange portion 110.
Referring to
Although not illustrated, a fastening structure may also be formed in a fastening portion 51a of the bearing housing 51 through tapping. The screw may pass through the tab hole 2121a and may be inserted into the fastening portion 51a. That is, the duct cover 100 may be coupled to both the tub back 200 and the bearing housing 51.
In this case, the duct cover 100 may be coupled to the tub back 200. Because the duct cover 100 has higher rigidity than the tub back 200, a rigidity of the exhaust flow path P may be secured. In addition, because the bearing housing 51, which has a higher rigidity than the tub back 200, is inserted into the tub back 200, rigidity reinforcement may be achieved at the same level as when the bearing housing 51 and the duct cover 100 of
With reference to
The bearing housing 51 may include a fastening portion 51b that protrudes through the tub back 200. For example, the fastening portion 51b may protrude rearward through a fastening protrusion 2121b formed on the tub back 200. That is, the fastening portion 51b may protrude rearward through the fastening protrusion 2121b.
A fastening structure may be formed in the fastening portion 51b of the bearing housing 51 through tapping, like the tab hole 2121a of
The fastening hole 110a of the duct cover 100 and the fastening portion 51b of the bearing housing 51 may be positioned to correspond to each other. When the fastening hole 110a is positioned to correspond to the fastening portion 51b, a screw may be inserted.
The duct cover 100 may be formed of the same material as the bearing housing 51. For example, both the duct cover 100 and the bearing housing 51 may be formed of Aluminum Die Casting (ALDC) or stainless steel. However, the disclosure is not limited thereto, and materials of the duct cover 100 and the bearing housing 51 are sufficient as long as the duct cover 100 and the bearing housing 51 are formed of a material having a higher rigidity than the material forming the tub 20.
In this case, the duct cover 100 may be directly coupled to the bearing housing 51. By directly coupling the duct cover 100 and the bearing housing 51, a rigidity of the exhaust flow path P may be reinforced. For example, in a case where the duct cover 100 and the bearing housing 51 are formed of Aluminum Die Casting (ALDC), which is similar to forming the exhaust flow path P by ALDC, and thus the rigidity of the exhaust flow path P This may be reinforced.

A distance between the rear frame 10c and the tub back 200 may increase toward a lower portion of the rear frame 10c. Conversely, the distance between the rear frame 10c and the tub back 200 may decrease toward an upper portion of the rear frame 10c.
In a case where the duct cover 100 has a predetermined thickness, interference may occur with the upper portion of the rear frame 10c having a short distance from the rear frame 10c. In this case, noise, and the like, may occur due to vibrations generated when the clothes care apparatus 1 operates.
In order to prevent/reduce the above, the duct cover 100 may include a cover inclined portion 122 in which a protruding length of a portion coupled to a lower side of the tub back 200 is formed to be longer than a protruding length of a portion coupled to an upper side of the tub back 200. The cover inclined portion 122 may be formed only on a portion of an upper portion of the duct cover 100.
For example, the cover inclined portion 122 may be formed to allow the length protruding rearward from the fastening flange portion 110 to increase toward the lower side of the tub back 200, so as to be spaced apart from the rear frame 10c of the housing 10 by a predetermined distance. That is, the length in which the connection portion 130 extends rearward may be longer at a portion coupled to the lower side of the tub back 200 than at a portion coupled to the upper side of the tub back 200.
In this instance, a cross-sectional area of the exhaust flow path P in the portion coupled to the upper side of the tub back 200 may be reduced, and thus a flow rate may also be reduced. To prevent the above, the recess portion 210 may include the step portion 211 formed above the recess portion 210. The step portion 211 may be formed adjacent to the duct connection portion 270.
The step portion 211 may be formed by recessing at least a portion of the recess portion 210 inward of the tub 20. That is, the step portion 211 may be formed by recessing forward above the recess portion 210. However, a shape of the step portion 211 is not limited thereto, and may be formed like the flow path expansion portion 211a shown in
Referring to
The cover portion 120 of the duct cover 100 may be formed to be spaced apart from the rear frame 10c of the housing 10 by a predetermined distance. Specifically, the cover portion 120 may be formed to be spaced apart from the rear recess portion 10ca and the rear frame 10c of the housing 10 by a predetermined distance.
Because the duct cover 100 is located at the rear of the tub back 200, the duct cover 100 may be adjacent to the rear frame 10c. In order for the duct cover 100 to be spaced apart from the rear frame 10c by a predetermined distance, an extension length of the connection portion 130 connecting the cover portion 120 and the fastening flange portion 110 may be formed to be short. That is, the duct cover 100 may be formed to be thin.
However, in a case where a thickness of the duct cover 100 is thin, a flow rate flowing through the exhaust flow path P may be reduced. In order to prevent the above, a maximum thickness of the duct cover 100 is required.
The cover portion 120 of the duct cover 100 may be formed to correspond to the rear frame 10c and the rear recess portion 10ca. A portion of the cover portion 120 may be formed in a stepped manner so as to be spaced apart from the rear frame 10c and the rear recess portion 10ca by a predetermined distance.
The cover portion 120 may be formed to have a portion protruding toward the rear recess portion 10ca. A portion of the cover portion 120 corresponding to the rear recess portion 10ca may protrude toward the rear recess portion 10ca. That is, a portion of the cover portion 120 corresponding to the rear recess portion 10ca may be formed to be stepped from the portion of the rear frame 10c other than the rear recessed portion 10ca. However, a shape of the duct cover 100 is not limited thereto, and may be provided in any shape as long as the duct cover 100 may be spaced apart from the rear frame 10c by a predetermined distance.
