[0041] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] See also Figure 1 and Figure 2 The embodiment of the present application provides a clothing processing device. The clothing processing device can be a washing and drying machine, or a clothes dryer, etc., and the present application does not limit this.

[0043] The clothes treating device comprises a housing 20 and a rear cover assembly 10 according to any one of the embodiments of the present application. The housing 20 and the rear cover assembly 10 together constitute an external frame structure of the clothes treating device.

[0044] The rear cover assembly 10 is disposed on the rear side of the box body 20. The rear side of the box body 20 is the rear side of the clothes processing device.

[0045] It should be noted that the “front side” and “rear side” refer to the horizontal directions of the clothing processing device when it is in normal use. For example, the clothing processing device is provided with a clothing inlet on one side in the horizontal direction, through which clothing can be put into and taken out of the clothing processing chamber of the clothing processing device. The side where the clothing inlet is located is the front side of the clothing processing device, and the side away from the clothing inlet is the rear side of the clothing processing device. Specifically, in the embodiments of the present application, the “front side” and “rear side” refer to Figure 1 or Figure 2 To understand.

[0046] Please also read Figures 1 to 8 The embodiment of the present application also provides a rear cover assembly, the rear cover assembly 10 includes a rear cover 11 and a noise reduction structure 12.

[0047] The rear cover 11 is used to cover at least a portion of the rear side of the box body 20. That is, the rear cover 11 can be understood as a component of the rear cover assembly 10 for realizing the function of covering at least a portion of the rear side of the box body 20.

[0048] It should be noted that the specific area of ​​the rear side of the box body 20 covered by the rear cover 11 is not limited. In some embodiments, the entire area of ​​the rear side of the box body 20 is covered by the rear cover 11. In other embodiments, the rear cover 11 only covers a portion of the rear side of the box body 20.

[0049] See also Figure 3 and Figure 5 The rear cover 11 is provided with an installation area 11a, and the noise reduction structure 12 is provided in the installation area 11a. The installation area 11a can provide an installation space for the noise reduction structure 12, thereby facilitating the installation of the noise reduction structure 12.

[0050] It should be noted that the specific structure of the installation area 11a is not limited. For example, the installation area 11a can be a space without a specific boundary on the rear cover 11. In this embodiment, the space on the rear cover 11 that can accommodate the noise reduction structure 12 can be understood as the installation area 11a. For another example, refer to Figure 5 The rear cover 11 includes a main body 111 and a rib plate 112. The main body 111 and the rib plate 112 are arranged to form an installation area 11a. The rib plate 112 and the main body 111 can be regarded as the boundaries of the installation area 11a.

[0051] Please refer to Figure 2 and Figure 4 The rear cover 11 is provided with a through hole 111a penetrating the wall of the mounting area 11a along the thickness direction of the rear cover 11. That is, the through hole 111a communicates the external space and the internal space of the laundry processing device.

[0052] The number of through holes 111a is not limited. Figure 4 The number of the through holes 111 a is multiple, that is, the wall of the installation area 11 a is penetrated by multiple through holes 111 a, so that the wall of the installation area 11 a is roughly in a grid-like structure.

[0053] It should be noted that the dimensions of different components in the three directions in the same absolute coordinate system are different. Generally, the length, width and thickness of the object are determined according to the dimensions of the object extending in the three directions. Length>width>thickness, so the length, width and thickness directions of different corresponding components may be different. Therefore, the following description will indicate which component’s length, width or thickness is.

[0054] It should be noted that, in the embodiment of the present application, the thickness direction of the rear cover 11 is consistent with the front-to-back direction of the clothes processing device.

[0055] See also Figure 2 , Figure 4 , Figures 6 to 8 The noise reduction structure 12 is provided with a guide channel 12a, and the fluid generated by the clothing processing device can pass through the guide channel 12a and the through hole 111a in sequence.

[0056] It should be noted that the specific type of "fluid" is not limited, and can be, for example, water vapor, air flow, or noise, or a combination thereof.

[0057] When the clothes treatment equipment performs the drying function, it will produce more water vapor. Figure 2 The box body 20 includes a rear plate 21, which is provided with a connecting hole 21a. The water vapor generated by the clothing processing device can be discharged to the outside of the clothing processing device through the steam hole 21a, the guide channel 12a and the exhaust hole 111a, thereby helping to reduce the accumulation of water vapor inside the clothing processing device, thereby causing liquid accumulation inside the clothing processing device and causing electrical safety problems.

[0058] The extension direction of at least a part of the flow guiding channel 12a is set at an angle to the thickness direction of the rear cover 11. In other words, the extension direction of at least a part of the flow guiding channel 12a is different from the extension direction of the through hole 111a. As a result, the noise generated by the clothing processing device will change its propagation direction when passing through the flow guiding channel 12a and the through hole 111a, and will not directly propagate to the outside of the clothing processing device along the thickness direction of the rear cover 11.

[0059] That is, the flow channel formed by the guide channel 12a and the through hole 111a does not extend in a straight line, and at least part of the flow channel is bent. When the noise generated inside the clothing processing equipment passes through the flow channel, the side wall of the guide channel 12a will have a certain blocking effect on the noise, which is beneficial to reduce the amount of noise leakage from the clothing processing equipment.

[0060] In the related art, a plurality of grid-shaped connecting holes are provided on the rear plate of the clothing treatment device. During the operation of the clothing treatment device, the water vapor generated is discharged to the outside of the dryer through these connecting holes. However, due to the small size of the rear plate in the thickness direction, it is difficult to set the connecting holes in a bent shape, that is, the connecting holes are straight holes extending directly in the thickness direction of the rear plate. When part of the noise generated by the clothing treatment device passes through these connecting holes, the side walls of the connecting holes have basically no blocking effect on this part of the noise, which makes the noise of the clothing treatment device relatively large. However, if the connecting holes are not provided, the water vapor generated by the clothing treatment device is difficult to be discharged to the outside, which leads to the accumulation of water vapor inside the clothing treatment device, and then causes liquid accumulation inside the clothing treatment device and electrical safety problems. Therefore, it is necessary to design a clothing treatment device that can ensure ventilation, thereby satisfying the discharge of water vapor, and reduce noise.

[0061] In the rear cover assembly of the embodiment of the present application, the rear cover assembly 10 is provided with a guide channel 12a and a through hole 111a. The rear cover assembly 10 is set on the rear side of the box 20 of the clothing processing device. The water vapor generated by the clothing processing device can be discharged to the outside of the clothing processing device through the guide channel 12a and the through hole 111a in sequence, thereby meeting the external discharge of water vapor from the clothing processing device; and the extension direction of at least part of the area of ​​the guide channel 12a is set at an angle with the thickness direction of the rear cover 11, that is, the flow channel formed by the guide channel 12a and the through hole 111a does not extend in a straight line, and at least part of the flow channel is bent. When the noise generated by the clothing processing device passes through the flow channel, it will collide with the side wall of the guide channel 12a, and the side wall of the guide channel 12a can thus produce a certain blocking effect on the noise, thereby helping to reduce the noise of the clothing processing device. That is to say, the rear cover assembly 10 of the embodiment of the present application can meet the external discharge of the fluid of the clothing processing device and is also helpful to reduce the noise of the clothing processing device.

[0062] It should be noted that the specific area where the rear cover 11 covers the rear side of the box body 20 is not limited. Figure 1 and Figure 2The box body 20 includes a rear plate 21, and the clothing processing device also includes a volute 30 and a fan. The volute 30 is arranged on the rear plate 21 and defines an air duct with the rear plate 21. The fan is arranged in the air duct. The rear cover 11 is arranged on the rear plate 21 and covers the volute 30. When projected on a plane perpendicular to the thickness direction of the rear cover 11, the projection of the air duct is located within the projection range of the rear cover 11.

[0063] That is to say, the area of ​​the rear cover 11 is larger than the area of ​​the volute 30. Thus, the fan can be completely covered by the rear cover 11. It can be understood that the fan will generate certain noise during operation. In addition to defining the air duct, the volute 30 can also form a first noise reduction for the noise generated by the fan, and the rear cover 11 can then perform a second noise reduction for the noise. That is, the volute 30 and the rear cover 11 work together to achieve double-layer noise reduction for the noise generated by the fan, which is conducive to further reducing the noise of the clothing processing device.

[0064] In one embodiment, the laundry processing device further includes a drum assembly, the drum assembly and the rear cover 11 are respectively located on opposite sides of the thickness direction of the rear plate 21, and when projected on a plane perpendicular to the thickness direction of the rear cover 11, the projection of the drum assembly is located within the projection range of the rear cover 11. Thus, the drum assembly can be completely covered by the rear cover 11.

[0065] The barrel assembly is rotatably disposed in the box body 30, and some noise will be generated during the rotation of the barrel assembly.

[0066] In this embodiment, the rear plate 21 forms a first noise reduction for the noise generated by the drum assembly, and the rear cover 11 performs a second noise reduction for the noise. That is, the rear plate 21 and the rear cover 11 work together to achieve double-layer noise reduction for the noise generated by the drum assembly, which is beneficial to further reduce the noise of the clothing processing equipment.

[0067] In one embodiment, please refer to Figure 1 and Figure 2 The rear plate 21 is provided with a connecting hole 21a along the thickness direction thereof, and the connecting hole 21a is located at the periphery of the air duct. The rear cover 11 is also provided with the connecting hole 21a, and the guide channel 12a is connected with the connecting hole 21a.

[0068] Therefore, the noise generated by the clothes processing device needs to pass through the connecting hole 21a, the guide channel 12a and the through hole 111a in sequence when propagating to the outside of the clothes processing device, so that the noise can be effectively reduced. In addition, the water vapor generated by the clothes processing device can also pass through the connecting hole 21a, the guide channel 12a and the through hole 111a in sequence and be discharged to the outside of the clothes processing device, thereby reducing the accumulation of water vapor inside the clothes processing device.

[0069] It is understandable that since the rear cover 11 needs to cover the air duct and the communication hole 21a, that is, the covering area of ​​the rear cover 11 is relatively large, the rear cover 11 needs to consider the problem of interference with the installation of more parts of the laundry processing device. Generally speaking, the size of the rear cover 11 in the thickness direction is reduced, so that the rear cover 11 is conveniently covered on the rear side of the box body 20, and the size of the laundry processing device in the front-to-back direction is not excessively increased.

[0070] Furthermore, since the dimension of the rear cover 11 in the thickness direction is relatively small, the through hole 111a can basically only be designed as a straight through hole extending in a straight line along the thickness direction of the rear cover 11, that is, the hole wall of the through hole 111a is difficult to block noise.

[0071] In the present embodiment, a noise reduction structure 12 is provided on the rear cover 11, and a guide channel 12a is provided on the noise reduction structure 12, that is, the rear cover 11 covers a large area on the rear side of the box body 20, and the noise reduction structure 12 can only cover the area where the connecting hole 21a is located. The noise reduction structure 12 does not need to cover a large area of ​​the box body 20, so that it is convenient to adjust the size of the noise reduction structure 12 in various directions. Therefore, the guide channel 12a is more convenient to design with at least a portion being bent, which is beneficial to simplify the structure of the rear cover assembly 10 and facilitate the rear cover assembly 10 to achieve the noise reduction function.

[0072] It should be noted that the material of the noise reduction structure 12 includes but is not limited to solid materials such as plastic and metal. In theory, the greater the density of the material used to prepare the noise reduction structure 12, the better the noise reduction effect of the noise reduction structure 12.

[0073] In one embodiment, please refer to Figure 2 , Figures 6 to 8 The guide channel 12a includes a plurality of sub-channels 12aa arranged along a first direction.

[0074] Exemplarily, the first direction is Figure 2 , Figure 6 or Figure 8 The direction shown by L1.

[0075] Each sub-channel 12aa extends along the second direction, and the inlet and the outlet of any sub-channel 12aa are arranged at intervals along the second direction, and the first direction and the second direction intersect.

[0076] Exemplarily, the second direction is Figure 2 , Figure 6 or Figure 8 The first direction and the second direction may be orthogonal, for example.

[0077] Of the two adjacent sub-channels 12aa, the sub-channel 12aa located upstream in the fluid flow direction is a first sub-channel, and the sub-channel 12aa located downstream in the fluid flow direction is a second sub-channel. The outlet of the first sub-channel is connected to the inlet of the second sub-channel.

[0078] It should be noted that the outlet of the first sub-channel can also be understood as the inlet of the second sub-channel. In other words, two adjacent sub-channels 12aa are connected through a communication port, and the communication port is both the outlet of the first sub-channel and the inlet of the second sub-channel.

[0079] It is understandable that when the noise passes through the guide channel 12a and propagates to the outside of the clothing processing device, it will propagate approximately along the second direction when passing through a certain sub-channel 12aa, and will propagate approximately along the first direction when propagating between multiple sub-channels 12aa. The first direction intersects with the second direction, and at least part of the guide channel 12a is bent. Therefore, during the propagation process, the noise will collide with the side wall of the guide channel 12a to change the propagation direction. The side wall of the guide channel 12a has a blocking effect on the noise, thereby reducing the amount of noise leakage.

[0080] In this embodiment, the guide channel 12a is generally folded, that is, multiple sub-channels 12aa are stacked along the first direction, and each sub-channel 12aa is set to extend along the second direction. This makes it convenient to set at least part of the guide channel 12a to be at an angle with the thickness direction of the rear cover 11.

[0081] It should be noted that the specific number of subchannels 12aa is not limited. Figure 8 , the number of sub-channels 12aa is two. The more sub-channels 12aa there are, the more times the noise changes its propagation direction in the guide channel 12a, and the greater the resistance encountered by the noise during propagation, and the better the noise reduction effect of the noise reduction structure 12. However, the resistance encountered by water vapor during the discharge process will also increase, which may reduce the discharge effect of water vapor. Setting the number of sub-channels 12aa to two is conducive to balancing the discharge effect of water vapor and the noise reduction effect of the clothing processing device.

[0082] Of course, through experimental tests, the number of sub-channels 12aa can be set more reasonably, so that the water vapor discharge effect and the noise reduction effect of the clothing processing equipment can be better taken into account.

[0083] It should be noted that the specific direction of the first direction is not limited. Figure 2 , Figures 6 to 8 The first direction is parallel to the thickness direction of the rear cover 11. That is, it is parallel to the front-rear direction of the laundry processing device.

[0084] In this embodiment, the second direction may be parallel to the height direction of the clothes treating apparatus.

[0085] It is understandable that, since it is necessary to take into account the effect of the guide channel 12a on the discharge of water vapor, the number of sub-channels 12aa is generally not too many, and the overall extension length of the guide channel 12a needs to be guaranteed, that is, the extension length of each sub-channel 12aa in the second direction will be larger. Therefore, the size of the noise reduction structure 12 in the first direction will be smaller than the size in the second direction. In this embodiment, the first direction is set to be parallel to the thickness direction of the rear cover 11, which is conducive to controlling the overall size of the rear cover assembly 10 in the front-to-back direction of the clothing processing device, that is, it is conducive to reducing the size of the clothing processing device in the front-to-back direction as much as possible.

[0086] In other embodiments, the first direction is parallel to the height direction of the laundry processing device. In this embodiment, the second direction can be parallel to the thickness direction of the rear cover 11, that is, parallel to the front-to-back direction of the laundry processing device. Thus, at least part of the guide channel 12a can also be bent.

[0087] Of course, when the clothes processing device needs to focus on the noise reduction effect, a larger number of sub-channels 12aa may be provided, so that the size of the noise reduction structure 12 in the first direction is larger than that in the second direction. Therefore, setting the first direction parallel to the height direction of the clothes processing device is conducive to reducing the size of the clothes processing device in the front-to-back direction as much as possible.

[0088] It should be noted that, for a specific sub-channel 12aa, the specific positions of the inlet and outlet of the sub-channel 12aa are not limited, and the inlet and outlet only need to be arranged at intervals along the second direction.

[0089] In some embodiments, at least one of the inlet and the outlet is located in a middle region of the sub-channel 12aa along the second direction.

[0090] In some other embodiments, please refer to Figure 7 and Figure 8 The inlet and the outlet of any sub-channel 12aa are respectively located at the opposite ends of the sub-channel 12aa along the second direction.

[0091] In other words, the sub-channels 12aa are connected end to end and together form the flow guiding channel 12a.

[0092] In this embodiment, when noise propagates in the guide channel 12a, its propagation path will cover the entire extension path of the guide channel 12a, and more side walls of the guide channel 12a can block the propagation of noise, which is beneficial to improving the noise reduction effect of the noise reduction structure 12.

[0093] The specific structure of the noise reduction structure 12 is not limited. Figures 6 to 8 The noise reduction structure 12 includes an outer plate 121 and a plurality of partition walls 122. The outer plate 121 is arranged to form a cavity 121a. The partition walls 122 are arranged on the cavity wall of the cavity 121a at intervals along the first direction. A sub-channel 12aa is defined between two adjacent partition walls 122 and the outer plate 121.

[0094] The outer plate 121 and the partition wall 122 may be an integrated structure. The outer plate 121 and the partition wall 122 may also be a split structure. Based on the outer plate 121 and the partition wall 122 of the split structure, the partition wall 122 may be welded to the cavity wall of the cavity 121a in sequence, thereby completing the processing of the noise reduction structure 12, and the processing and molding of the noise reduction structure 12 is more convenient.

[0095] In this embodiment, a plurality of sub-channels 12aa arranged along the first direction can be formed by the outer plate 121 and the partition wall 122. Therefore, there is no need to form the sub-channels 12aa by punching or the like on the noise reduction structure 12, which facilitates the forming of the sub-channels 12aa and is beneficial to the processing of the noise reduction structure 12.

[0096] In one embodiment, please refer to Figures 6 to 8 The end walls of the partition wall 122 at the opposite ends along the second direction are respectively the first end wall 122a and the second end wall 122b, and the two partition walls 122 corresponding to any sub-channel 12aa are respectively the first partition wall and the second partition wall; the first end wall 122a of the first partition wall and the cavity wall of the cavity 121a are arranged to form a first connecting port, and the second end wall 122b of the second partition wall and the cavity wall of the cavity 121a are arranged to form a second connecting port, one of the first connecting port and the second connecting port is the entrance of the sub-channel 12aa, and the other is the outlet of the sub-channel 12aa.

[0097] That is, for a specific sub-channel 12aa, the inlet and the outlet of the sub-channel 12aa are located at opposite ends of the sub-channel 12aa along the second direction.

[0098] Here, there is no need to open holes on the partition wall 122 to connect two adjacent sub-channels 12aa. During the production of the partition wall 122, it is only necessary to process the partition wall 122 into a plate-like structure. Therefore, the structure of the partition wall 122 is relatively simple and easy to produce.

[0099] When noise propagates in the guide channel 12a, the propagation path is roughly S-shaped, that is, it enters from one end of the sub-channel 12aa along the second direction and leaves from the other end. This is conducive to making full use of the size of the noise reduction structure 12 in the second direction to set the guide channel 12a, thereby further improving the noise reduction effect of the noise reduction structure 12.

[0100] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The rear cover 11 is provided with an avoidance area 11b, which is used to avoid the volute 30 of the clothing processing device. The outer plate 121 includes a first sub-plate 1211, which is located on a side of the outer plate 121 close to the avoidance area 11b. At least a portion of the first sub-plate 1211 is recessed in a direction away from the avoidance area 11b and forms an arc segment 1211a.

[0101] The outer edge of the volute 30 is roughly arc-shaped, and the first sub-plate 1211 is set as an arc segment 1211a, so that it can match the outer edge of the volute 30, which is conducive to making full use of the space on the rear cover 11, thereby maximizing the overall size of the noise reduction structure 12, and the overall size of the guide channel 12a can also be designed to be larger, thereby facilitating the design of the guide channel 12a to be bent. At the same time, it is also conducive to extending the extension length of the guide channel 12a, thereby further improving the noise reduction effect of the noise reduction structure 12.

[0102] In one embodiment, please refer to Figure 6 The peripheral board 121 also includes a second sub-board 1212 and a third sub-board 1213. The two ends of the first sub-board 1211 are respectively connected to one end of the second sub-board 1212 and one end of the third sub-board 1213, the other end of the second sub-board 1212 is connected to the other end of the third sub-board 1213, and the extension direction of the second sub-board 1212 is orthogonal to the extension direction of the third sub-board 1213.

[0103] It can be understood that, when the position of the connection between the second sub-plate 1212 and the third sub-plate 1213 is determined, and the position and shape of the first sub-plate 1211 are determined, when the angle between the second sub-plate 1212 and the third sub-plate 1213 is 90°, the area of ​​the area enclosed by the first sub-plate 1211, the second sub-plate 1212 and the third sub-plate 1213 is the largest. In other words, in this embodiment, it is beneficial to fully utilize the space on the rear cover 11, thereby increasing the overall size of the noise reduction structure 12 as much as possible, and the overall size of the guide channel 12a can also be designed to be larger, thereby facilitating the design of the guide channel 12a as a bent shape, and at the same time, it is also beneficial to extend the extension length of the guide channel 12a, thereby further improving the noise reduction effect of the noise reduction structure 12.

[0104] In one embodiment, please refer to Figure 5 The rear cover 11 includes a main body 111 and a rib plate 112 . The main body 111 is used to cover the box body 20 . The rib plate 112 is arranged on a side of the main body 111 facing the box body 20 and is surrounded by the main body 111 to form an installation area 11a . The through hole 111a is arranged on the main body 111 .

[0105] In this embodiment, a portion of the circumferential boundary of the installation area 11a can be determined by the rib plate 112. When the noise reduction structure 12 is installed on the rear cover 11, the rib plate 112 can facilitate the operator to determine the installation position of the noise reduction structure 12, thereby facilitating the improvement of the assembly efficiency of the rear cover assembly 10. In addition, the rib plate 112 can limit the noise reduction structure 12, facilitating the improvement of the installation stability of the noise reduction structure 12 on the rear cover 11.

[0106] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The rear cover 11 is also provided with an escape area 11b, which is used to avoid the volute 30 of the clothing processing device. At least part of one side of the rib plate 112 in the thickness direction constitutes the side wall of the installation area 11a, and at least part of the other side constitutes the side wall of the escape area 11b.

[0107] That is to say, the rib plate 112 is used to separate the installation area 11a and the avoidance area 11b. At the junction of the installation area 11a and the avoidance area 11b, the rib plate 112 is used to separate them. The dimension of the rib plate 112 in the thickness direction is relatively small, and it will not occupy too much space on the rear cover 11. Therefore, when the avoidance area 11b is determined, the space of the installation area 11a can be increased as much as possible, so as to meet the installation of a larger size noise reduction structure 12.

[0108] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The avoidance area 11b extends along the diagonal of the rear cover 11, and there are two installation areas 11a. The two installation areas 11a are respectively located on both sides of the avoidance area 11b, and the connecting line between the two installation areas 11a intersects with the extension direction of the avoidance area 11b. Both installation areas 11a are provided with a noise reduction structure 12.

[0109] The housing 20 and the rear cover 11 are both roughly square structures. Since the size of the volute 30 is relatively large, in order to facilitate the control of the overall size of the laundry processing device, the volute 30 is generally installed on the housing 20 at an angle, and the avoidance area 11b extends along the diagonal of the rear cover 11, so as to match the volute 30.

[0110] It is understandable that after the rear cover assembly 10 is installed on the box body 20, the space size in the extension direction of the avoidance area 11b is limited, while the space on both sides of the avoidance area 11b is relatively sufficient. Therefore, the installation area 11a is set on both sides of the avoidance area 11b, and the noise reduction structure 12 is set in the installation area 11a, so that the space between the rear cover 11 and the box body 20 can be fully utilized, which is conducive to improving the discharge efficiency of water vapor.

[0111] The clothing processing device of the embodiment of the present application has a rear cover assembly 10, and the noise reduction structure 12 reduces the noise by more than 10db within a wide frequency range, that is, it has a good noise reduction effect within a wide frequency range.

[0112] Specifically, when the clothes processing equipment is unloaded, the noise of the clothes processing equipment before and after the improvement is tested under different programs. The specific test results are as follows:

[0113] When the noise program (10kg) was running, it was 51.3db before improvement and 48db after improvement.

[0114] When the energy efficiency program (10kg) was running, the value before improvement was 61.4db, and the value after improvement was 59.4db.

[0115] When the fast drying program (3kg) was running, the value before improvement was 63.1db, and the value after improvement was 60.9db.

[0116] When the wool program (3kg) was running, it was 61.1db before improvement and 58.8db after improvement.

[0117] According to experimental data, the noise of clothing processing equipment can be reduced by about 2db under different operating programs.
