[0031] According to the embodiments of the present application, a housing assembly 100 is provided, as shown in Figure 2 and Figure 3 The housing assembly 100 includes an inner cover 10 and an outer cover 30, specifically, the inner cover 10 and the outer cover 30 are both invertedly buckled on a rear plate 20 in a clothes processing apparatus 200, the inner cover 10 defines an air duct 101 for accommodating an impeller 210, the outer cover 30 is arranged outside the inner cover 10, the outer cover 30 is arranged in a spaced manner with the inner cover 10, and a gap space 102 for filling with heat insulation and other materials is defined between the outer cover 30 and the inner cover 10, and the gap space 102 forms an opening 1021 between the edge of the inner cover 10 and the edge of the outer cover 30.

[0032] The housing assembly 100 further includes a flange structure, which is arranged on the inner cover 10 or the outer cover 30, or both the inner cover 10 and the outer cover 30, and is used to be fitted with the rear plate 20 of the clothes processing apparatus, so as to increase the contact surface area between the inner cover 10 or the outer cover 30 and the rear plate 20, thereby improving the sealing performance between the inner cover 10 or the outer cover 30 and the rear plate 20, effectively reducing the air leakage amount of the airflow in the air duct 101 into the gap space 102, or reducing the air leakage amount of the airflow in the air duct 101 through the gap between the inner cover 10 or the outer cover 30 and the rear plate 20 to the outside of the air duct 101, thereby reducing the air volume loss.

[0033] In detail, the flanging structure includes a first flange 13, which in some embodiments is arranged on the inner cover 10 and is folded towards the outer cover 30, and the first flange 13 covers at least part of the opening 1021, thereby effectively reducing the air flow in the air duct through the opening 1021 and flowing into the gap space, reducing the air volume loss. For example, the first flange 13 can completely close the opening 1021 to prevent the air flow in the air duct from flowing into the gap space through the opening 1021. In other embodiments, the first flange 13 is arranged on the outer cover 30 and is folded towards the inner cover 10, and the first flange 13 covers at least part of the opening 1021, thereby effectively reducing the air flow in the air duct through the opening 1021 and flowing into the gap space, reducing the air volume loss.

[0034] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the air duct 101 includes a mounting area 1011 and a blowing area 1012 connected in communication, the mounting area 1011 is used to mount the impeller 210, the impeller 210 rotates in the mounting area 1011 and generates air flow, the air flow flows from the mounting area 1011 to the blowing area 1012, and the air flow is delivered to other components or drying areas inside the clothes dryer through the blowing area 1012. In this embodiment, the first flange 13 is arranged around the mounting area 1011, and one end of the first flange 13 away from the inner cover 10 is arranged in spaced relation to the outer cover 30, that is, a gap is provided between the first flange 13 and the outer cover 30, so that the first flange 13 is arranged in spaced relation to the outer cover 30 to provide better buffering space for vibration, avoiding the vibration generated during the operation of the impeller 210 being directly transmitted to the outer cover 30 through the first flange 13, and avoiding mutual interference due to the contact between the inner cover 10 and the outer cover 30. Understandably, if the first flange 13 directly contacts the outer cover 30, friction noise may be generated due to vibration during the operation of the clothes dryer, increasing noise, and therefore, the first flange 13 is arranged in spaced relation to the outer cover 30 to effectively reduce the friction noise.

[0035] In other embodiments, the first flange 13 is arranged around the mounting area 1011, and one end of the first flange 13 away from the inner cover 10 abuts the outer cover 30, so that the first flange 13 completely closes the opening 1021 of the gap space 102 around the mounting area 1011, and can effectively prevent the air flow from entering the inside of the gap space 102 through the opening 1021 in the case of strong air flow generated by high-speed rotation of the impeller 210.

[0036] In some embodiments, please refer to Figure 2 and Figure 3 As shown in Figure 2 and Figure 3As shown, the inner cover 10 includes an inner cover bottom plate 11 and an inner cover side plate 12, the inner cover bottom plate 11 is parallel and spaced apart from the back plate 20, and the inner cover side plate 12 is connected to the inner cover bottom plate 11 and extends around the edge of the inner cover bottom plate 11, and the end of the inner cover side plate 12 away from the inner cover bottom plate 11 is connected to the back plate 20.

[0037] The outer cover 30 includes an outer cover bottom plate 31 and an outer cover side plate 32, the outer cover bottom plate 31 is parallel and spaced apart from the inner cover bottom plate 11, and the outer cover side plate 32 is connected to the outer cover bottom plate 31 and extends along the edge of the outer cover bottom plate 31, and the outer cover side plate 32 is spaced apart from the inner cover side plate 12, so that the outer cover 30 as a whole covers the outside of the inner cover 10, and the end of the outer cover side plate 32 away from the outer cover bottom plate 31 is connected to the back plate 20. In this embodiment, the purpose of arranging the outer cover 30 outside the inner cover 10 is to achieve heat insulation and noise reduction. Specifically, during the operation of the clothes dryer, the heating device inside the air duct 101 will cause the temperature inside the air duct 101 to rise, and the inner cover 10 and the back plate 20 are mainly used to guide and accommodate airflow, and in this process, the inner cover 10 is heated, and the gap space 102 formed between the outer cover 30 and the inner cover 10 and the back plate 20 can act as a poor conductor of heat, effectively blocking the transfer of heat outward, on the one hand, preventing the inner cover 10 from scalding the user, and on the other hand, the heat insulation performance of the gap space 102 helps to reduce the loss of heat inside the clothes dryer, thereby reducing energy consumption.

[0038] It should be further noted that there are mechanical components such as motors and impellers 210 inside the clothes dryer, which will generate some noise, and the gap space 102 between the outer cover 30 and the inner cover 10 can act as a buffer and sound absorber. For example, when the vibration generated by the operation of the motor is transmitted to the inner cover 10 and the back plate 20, the sound-absorbing material such as sound-absorbing cotton filled in the gap space 102 can absorb part of the vibration energy and reduce the noise propagation outward.

[0039] Further, the gap space 102 can provide buffer protection for the inner cover 10 and the internal impeller 210. For example, during the transportation of the clothes dryer or when it is slightly bumped from the outside, the filler in the gap space 102 can absorb the impact force and reduce the risk of damage to the inner cover 10 and internal components (such as the impeller 210, heating pipe, sensor, etc.) due to vibration.

[0040] In some embodiments, please refer to Figure 2 and Figure 3As shown, the second flange 33 is connected to the rear plate 20 through a bolt or other connecting member. The second flange 33 on the outer cover side plate 32 is attached to the rear plate 20, so that the outer cover 30 can be more firmly mounted on the rear plate 20 of the clothes dryer, so that the cover assembly 100 of the clothes dryer forms a more compact overall structure. This helps to improve the mechanical stability of the entire clothes dryer and reduce the relative movement between the parts. During the operation of the clothes dryer, due to the rotation of the internal impeller 210 and the flow of air flow, a certain vibration will be generated, and the second flange 33 attached to the rear plate 20 can effectively prevent the outer cover 30 from being displaced due to vibration. It should be noted that the second flange 33 can reduce the noise leakage caused by the gap between the outer cover 30 and the rear plate 20, and prevent the spread of noise. The second flange 33 is attached to the surface of the rear plate 20 to enhance the sealing of the outer cover 30, and to prevent dust, moisture and other impurities from entering the interior of the clothes dryer.

[0041] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the second flange 33 includes a third bending portion 331 and a fourth bending portion 332, the third bending portion 331 is connected to the outer cover side plate 32, the fourth bending portion 332 is connected to one end of the third bending portion 331 away from the outer cover side plate 32, the third bending portion 331 is attached to the surface of the rear plate 20, and the fourth bending portion 332 is arranged at an angle with the third bending portion 331 and is folded away from the rear plate 20. In detail, the third bending portion 331 is attached to the surface of the rear plate 20 to provide a connecting surface for connecting to the rear plate 20, so that the outer cover 30 can be stably connected to the rear plate 20. The fourth bending portion 332 is arranged at an angle with the third bending portion 331 and is folded away from the rear plate 20, which can effectively increase the overall structural strength of the second flange 33 and improve the connection structural strength between the outer cover 30 and the rear plate 20.

[0042] According to an embodiment of the present application, a clothes processing equipment 200 is also provided, please refer to Figure 1 , Figure 2 and Figure 3 As shown, the clothes processing equipment 200 can be a clothes dryer or a dry cleaning integrated machine, the clothes processing equipment 200 includes a clothes processing drum and a cover assembly 100, the air duct 101 of the cover assembly 100 is connected to the clothes processing drum, and the clothes processing equipment further includes a rear plate 20 and an impeller 210, the impeller 210 is arranged in the air duct 101 of the cover assembly 100, and the rear plate 20 is provided with a ventilation opening (not shown in the figure) for communicating the clothes processing drum and the air duct 101.

[0043] In this embodiment, the laundry treatment device 200 further comprises a cabinet, a motor, etc. The laundry treatment drum is arranged in the cabinet, and the laundry treatment drum is provided with an air inlet hole opposite and communicating with the air vent. The first end of the motor shaft is used to output driving force to the laundry treatment drum, for example, the first end of the motor shaft drives the laundry treatment drum to rotate through a belt, and the second end of the motor shaft drives the impeller 210 to rotate. That is, the motor shaft simultaneously drives the laundry treatment drum and the impeller 210 to rotate.

[0044] The laundry treatment device is further provided with a circulating air duct (not shown in the figure), and the laundry treatment drum is provided with an air outlet (not shown in the figure), which is connected in communication with the air duct 101 through the circulating air duct. The impeller 210 guides the airflow flowing through the circulating air duct into the air duct 101 of the inner cover 10, and the airflow in the air duct 101 enters the laundry treatment drum through the air vent and the air inlet hole. Specifically, in the rotation process of the impeller 210, the airflow in the air duct 101 is pumped into the laundry treatment drum, and at the same time, negative pressure is generated at the air inlet of the impeller 210. The airflow in the circulating air duct is supplemented into the inner cover 10 under the action of the negative pressure.

[0045] The airflow direction in the air duct 101 is indicated by the arrow in the figure. Figure 1 The airflow direction in the air duct 101 is indicated by the arrow in the figure.

[0046] The cabinet comprises a left support plate, a right support plate, and a rear plate 20 connected between the left support plate and the right support plate.

[0047] The assembly relationship between the cover assembly 100 and the cabinet can be set in multiple ways, which is not specifically limited here. For example, in some embodiments, the cover assembly 100 is arranged at the rear side of the rear plate 20 of the cabinet, the front side of the inner cover 10 is open, and the rear plate 20 closes the to-be-closed area of the open part of the inner cover 10. The air vent is located at the open part of the inner cover 10, and the airflow of the inner cover 10 enters the laundry treatment drum through the air vent and the air inlet hole.

[0048] Further, the end of the inner cover side plate 12 away from the inner cover bottom plate 11 is provided with a first flange 13, and the first flange 13 is attached to the surface of the rear plate 20 away from the laundry treatment drum. By tightly attaching the first flange 13 to the rear plate 20, a sealing boundary around the mounting area 1011 is formed between the rear plate 20 and the inner cover 10, improving the sealing between the inner cover 10 and the rear plate 20. In the case of strong airflow generated by high-speed rotation of the impeller 210, the airflow can be effectively prevented from leaking out of the gap between the rear plate 20 and the inner cover 10, so that the airflow generated by the impeller 210 can more concentratedly enter the air supply area 1012.

[0049] It is also needed to be emphasized that when the air flow generated by the rotation of the impeller 210 is effectively guided and well sealed at the installation area 1011, the noise caused by the disorder and leakage of the air flow can be reduced. Because the disorder diffusion and leakage of the air flow often cause air vibration, and further generate noise. By arranging the first flange 13 around the installation area 1011, the air flow is more orderly, the air vibration source is reduced, and thus the noise during the operation of the clothes dryer is reduced.

[0050] According to the clothes treatment equipment of the utility model, through setting first flange 13 at inner cover 10, on one hand, through first flange 13 increase the structural strength of inner cover 10, reduce the jitter of inner cover 10 when impeller 210 operates, reduce the noise when operating, on the other hand, through first flange 13 and the plate face of rear plate 20 are conformed, increase the connection and contact area between inner cover 10 and rear plate 20, make the connection between inner cover 10 and rear plate 20 more closely, effectively reduce the gap between inner cover 10 and rear plate 20. In the operation process of the clothes dryer, the air flow generated by the impeller 210 can be better constrained in the air duct 101, the air volume leaked from the gap is reduced, and the drying efficiency of the clothes dryer is improved.

[0051] In some embodiments, please refer to Figure 2 and Figure 3 It is shown that the rear plate 20 is provided with a concave structure 21 for accommodating the impeller 210, the concave structure 21 is located at the area opposite to the installation area 1011 of the rear plate 20, the concave structure 21 includes a bottom wall 211 and a side wall 212 connected with the bottom wall 211, the bottom wall 211 is oppositely and spacedly arranged with the inner cover bottom plate 11, the impeller 210 is arranged between the bottom wall 211 and the inner cover bottom plate 11, the bottom wall 211 provides support for the impeller 210, the side wall 212 extends from the bottom wall 211 to the direction of the inner cover bottom plate 11, the first flange 13 of the inner cover 10 is conformed with the wall surface of the side wall 212, so that the connection between the inner cover 10 and the rear plate 20 at the installation area 1011 is more closely and accurately. The first flange 13 is conformed with the wall surface of the side wall 212 of the concave structure 21, which further enhances the sealing effect of the installation area 1011. In the embodiment, the concave structure 21 is a recessed structure made of sheet metal stamping process of the rear plate 20, the bottom wall 211, the side wall 212 and other parts of the rear plate 20 are an integral structure.

[0052] In some embodiments, please refer to Figure 2 and Figure 3As shown, the side wall 212 includes a first side wall 2121 connected with the bottom wall 211 and a second side wall 2122 connected with the first side wall 2121 away from the bottom wall 211, and the first side wall 2121 is arranged at an angle with the bottom wall 211 and the second side wall 2122 respectively. The first flange 13 includes a first bending part (not shown in the figure) connected with the inner cover side plate 12 and a second bending part (not shown in the figure) connected with the first bending part away from the inner cover side plate 12, the first bending part is fitted with the wall surface of the first side wall 2121, and the second bending part is fitted with the wall surface of the second side wall 2122. In the embodiment, the fitting of the first bending part and the second bending part with the first side wall 2121 and the second side wall 2122 respectively forms a multi-dimensional sealing structure, which can more effectively prevent air flow from leaking from the installation area 1011, and compared with the case of only single edge fitting, the air volume loss can be further reduced, and the tightly fitted double flanges and double side walls 212 structure can also reduce the noise and vibration caused by air flow leakage and turbulence.

[0053] In some embodiments, please refer to Figure 2 and Figure 3 As shown, the first flange 13 is folded towards the outside of the air duct 101, so that the first flange 13 is located outside the air duct 101, making the inside of the air duct 101 more flat. It should be noted that if the first flange 13 occupies the space inside the air duct 101, it may cause turbulence of the air flow when passing through the area where the first flange 13 is located. In the embodiment, the first flange 13 is located outside the air duct 101, so that the air flow can flow smoothly in the air duct 101, improving the transmission efficiency of the air flow in the entire air duct 101, and ensuring that sufficient air volume reaches the drying area of the clothes dryer in time. And by folding the first flange 13 towards the outside of the air duct 101, interference to the air flow is avoided, and noise caused by turbulence of the air flow around the first flange 13 is also reduced.

[0054] In other embodiments, the first flange 13 is located in the gap space 102, and the first flange 13 is spaced apart from the outer cover 30. The spaced arrangement of the first flange 13 and the outer cover 30 can provide better buffer space for vibration, avoiding the vibration generated during the operation of the impeller 210 being directly transmitted to the outer cover 30 through the first flange 13, and avoiding mutual interference caused by the contact between the inner cover 10 and the outer cover 30. Understandably, if the first flange 13 and the outer cover 30 are in direct contact, friction noise may be generated due to vibration during the operation of the clothes dryer, increasing noise. Therefore, the spaced arrangement of the first flange 13 and the outer cover 30 can effectively reduce the friction noise.

[0055] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
