DETAILED DESCRIPTION

[0061] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0063] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0064] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0065] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" or "above" a second feature includes that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0066] In order to simplify the difficulty of production and processing, the air duct shell assembly of the traditional clothing processing equipment is formed into two parts in the thickness direction, namely the plate part and the shell part, respectively, and then the two are connected by fasteners so that the two together define a ventilation cavity. Since the shell part and the plate part are connected by fasteners, the installation cost of the clothing processing equipment is high, the sealing performance of the connection between the two is affected by the installation process, and the ventilation cavity has poor sealing, which in turn affects the air volume entering the clothing processing cavity of the clothing processing equipment. In addition, the depth and volume of the clothing processing cavity are limited by the size of the space in front of the support plate. The clothing processing cavity cannot accommodate more clothes, affecting the user experience.

[0067] To this end, the embodiment of the utility model designs a clothing processing device with an integrally formed support plate 12131, and the support plate 12131 defines a portion of the ventilation cavity, and a portion of the clothing processing cavity extends into the partial ventilation cavity defined by the support plate 12131. Since the support plate 12131 is formed as an integral piece, the assembly cost is reduced, the sealing performance of the partial ventilation cavity defined by it is better, and the clothing processing cavity can extend into the first ventilation cavity, thereby increasing the depth of the clothing processing cavity without changing the overall thickness of the clothing processing device, thereby increasing the capacity of the clothing processing cavity.

[0068] Reference below Figure 1-Figure 12 A clothes treating apparatus according to an embodiment of the present invention is described.

[0069] The laundry processing apparatus according to the embodiment of the present invention may include: a laundry processing drum assembly 2 and a support plate 12131 .

[0070] Among them, the support plate 12131 is integrally formed with a first ventilation cavity 102 having a first opening 1011, and the first ventilation cavity 102 connects the clothing processing cavity 201 and the air duct. The support plate 12131 is an integrally formed part. Compared with the plate structure that only includes a plane in the prior art, the support plate 12131 in the embodiment of the utility model itself defines a first ventilation cavity 102 having a first opening 1011, and the first ventilation cavity 102 is formed as a part of the air inlet close to the clothing processing cavity 201 in the ventilation cavity that connects the air outlet of the clothing processing cavity 201 and the air inlet of the clothing processing cavity 201.

[0071] Since the first ventilation cavity 102 is partially defined by the integrally formed support plate 12131, the sealing performance of the first ventilation cavity 102 is better, and since the support plate 12131 is integrally formed, the assembly cost of the clothing processing apparatus is reduced.

[0072] Furthermore, the first ventilation cavity 102 extends along the thickness direction of the support plate 12131, that is, the first opening 1011 and the first ventilation cavity 102 are relatively arranged and connected in the thickness direction of the support plate 12131. Therefore, the support plate 12131 can be stamped integrally from a plate, which simplifies the molding method of the support plate 12131 and reduces the production cost of the support plate 12131.

[0073] The clothing processing drum defines a clothing processing chamber 201 and has an air inlet 2231, which connects the first ventilation chamber 102 and the clothing processing chamber 201. The airflow only needs to pass through the air inlet 2231 to enter the clothing processing chamber 201 from the first ventilation chamber 102, thereby greatly reducing the wind resistance of the airflow in the process of flowing into the clothing processing chamber 201. At least part of the structure of the clothing processing drum assembly 2 can extend into the first ventilation chamber 102 through the first opening 1011, thereby increasing the capacity of the clothing processing chamber 201 without changing the overall thickness of the clothing processing device. The clothing processing chamber 201 can accommodate more clothing, thereby improving the user experience.

[0074] According to the clothing processing device of the embodiment of the utility model, the clothing processing device adopts an integrally formed support plate 12131, which reduces the assembly cost and improves the sealing performance of the gas flow channel. The clothing processing chamber can extend into the first ventilation chamber 102, thereby increasing the depth of the clothing processing chamber 201 without changing the overall thickness of the clothing processing device, thereby increasing the capacity of the clothing processing chamber 201.

[0075] like Figure 9-12 As shown, the clothing processing drum assembly 2 has a first extension portion 223, which extends from the first opening 1011 into the first ventilation cavity 102 and defines a portion of the clothing processing cavity 201. The first extension portion 223 and the portion of the clothing processing cavity 201 defined by the first extension portion 223 can increase the capacity of the clothing processing cavity 201, and the air inlet portion 2231 is arranged on the first extension portion 223, so that the air inlet portion 2231 can directly connect the first ventilation cavity 12 and the clothing processing cavity 201.

[0076] Furthermore, the support plate 12131 is provided with a first opening 1011 and an air outlet 1013, wherein, in the first ventilation cavity 102, air flows from the air outlet 1013 to the first opening 1011, the first opening 1011 is connected to the air inlet 2231 of the clothing processing cavity 201, and the air outlet 1013 is connected to the air outlet of the clothing processing cavity 201.

[0077] The air vent 1013 is provided on the cavity wall of the first ventilation cavity 102 and connects the first ventilation cavity 102 and the air duct. The air duct connected between the air outlet of the clothing processing cavity 201 and the air vent 1013 can be defined by other structures themselves or by other structures and the support plate 12131, and the two can be processed and formed by different materials, wherein the support plate 12131 part can be made of high-strength and high-quality materials, while other structures can be made of relatively low-strength, low-density and low-priced materials, so as to reduce the production cost of the clothing processing components and realize the lightweight of the clothing processing equipment.

[0078] Reference Figure 1-Figure 9 The projection of the cavity wall of the first ventilation cavity 102 on the plane where the first opening 1011 is located is located inside the first opening 1011, so that the support plate 12131 can be stamped integrally from the plate. Before the support plate 12131 is stamped, the material at the position corresponding to the first opening 1011 on the plate is stamped to form a structure corresponding to the cavity wall of the first ventilation cavity 102.

[0079] Since the air outlet 1013 is arranged on the cavity wall of the first ventilation cavity 102, the projection of the cavity wall of the first ventilation cavity 102 on the plane where the first opening 1011 is located is located in the first opening 1011, therefore, the projection of the air outlet 1013 on the plane where the first opening 1011 is located is located in the first opening 1011.

[0080] Combination Figure 1-Figure 9 In the illustrated embodiment, the projection area of ​​the air outlet 1013 in the plane where the first through hole 1011 is located is less than half of the area of ​​the first through hole 1011 .

[0081] In order to ensure the sealing performance of the ventilation cavity connecting the inlet and outlet of the clothing processing cavity 201, it is necessary to design a structure to cover the air outlet 1013. When the air outlet 1013 is designed to be too large, it will affect the production cost of the structure covering the air outlet 1013 and make the assembly and sealing cost between the structure and the support plate 12131 higher.

[0082] Furthermore, when the projection area of ​​the air outlet 1013 in the plane where the first opening 1011 is located is larger than half of the area of ​​the first opening 1011, the air outlet 1013 will cover the center position of the first opening 1011, that is, the support plate 12131 structure cannot cover the center position of the first opening 1011. When the support plate 12131 needs to assume the function of supporting the clothing processing barrel assembly, the clothing processing barrel cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing processing barrel assembly 2, which may cause the clothing processing barrel assembly 2 to be unstable.

[0083] Furthermore, when the clothing processing drum assembly 2 is connected to other structures covering the center position of the first opening 1011, in order to improve the strength of the structure connected to the clothing processing drum assembly 2, this part of the structure needs to be designed with a reinforcing structure 1316 or needs to use high-strength metal materials to ensure its support stability for the clothing processing drum assembly 2, thereby increasing the overall production cost of the clothing processing equipment.

[0084] Reference Figure 2 , the projection of the air outlet 1013 on the plane where the first opening 1011 is located extends along the first direction, and the second direction is the radial direction of the first opening 1011 and is perpendicular to the first direction. Since the first opening 1011 is formed as a circular hole, the first opening 1011 and the first ventilation cavity 102 are arranged opposite to each other in the thickness direction of the support plate 12131, so the intersection line of the cavity wall of the first ventilation cavity 102 and the plane where the first opening 1011 is located is arranged around the first opening 1011. The cavity wall of the first ventilation cavity 102 includes a side wall and a rear wall, the side wall is arranged around the rear wall and is connected to the edge of the first opening 1011, the air outlet 1013 includes a part arranged on the side wall of the first ventilation cavity 102 and a part arranged on the rear wall of the first ventilation cavity 102, the part of the air outlet 1013 arranged on the side wall of the first ventilation cavity 102 mainly affects the size of the air outlet 1013 in the first direction, and the part of the air outlet 1013 arranged on the rear wall of the first ventilation cavity 102 mainly affects the size of the air outlet 1013 in the second direction.

[0085] Among them, the dimension X of the projection of the air outlet 1013 in the first direction is 0.2-0.8 times the diameter of the first opening 1011, that is, the distance between the two ends of the part of the air outlet 1013 arranged on the side wall of the first ventilation cavity 102 in the circumferential direction of the first opening 1011 is 0.2-0.8 times the diameter of the first opening 1011. When the dimension of the projection of the air outlet 1013 in the first direction is less than 0.2 times the diameter of the first opening 1011, the opening area of ​​the air outlet 1013 is too small, which affects the ventilation performance at the air outlet 1013, and further affects the drying performance of the clothing processing equipment.

[0086] When the projection of the air outlet 1013 in the first direction is larger than 0.8 times the diameter of the first opening 1011, the area of ​​the air outlet 1013 on the side wall of the first ventilation cavity 102 is too large, which affects the connection length between the corresponding structure of the cavity wall of the first ventilation cavity 102 and the main part of the support plate 12131, and further affects the strength of the corresponding structure of the cavity wall of the first ventilation cavity 102. The strength of the corresponding structure of the cavity wall of the first ventilation cavity 102 cannot stably support the external structure, and the stability of the overall setting of the clothing processing equipment is low.

[0087] The dimension Y of the projection of the air outlet 1013 in the second direction is 0.1-0.4 times the diameter of the first opening 1011. When the dimension of the projection of the air outlet 1013 in the second direction is greater than 0.4 times the diameter of the first opening 1011, the air outlet 1013 will be close to or cover the center position of the first opening 1011, thereby causing the structure of the support plate 12131 to be unable to cover the center position of the first opening 1011 or the peripheral position of the center position. When the support plate 12131 needs to assume the function of supporting the clothing processing barrel assembly, the support plate 12131 cannot be provided with a bearing seat 111 or other structures for connecting with the clothing processing barrel assembly 2 at the corresponding position of the center of the first opening 1011. As a result, the clothing processing barrel cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing processing barrel assembly 2, resulting in an unstable setting of the clothing processing barrel assembly 2.

[0088] When the projection of the air outlet 1013 in the second direction is smaller than 0.1, the opening area of ​​the air outlet 1013 will be too small, affecting the ventilation performance at the air outlet 1013. It will also cause the support plate 12131 structure to cover an area that is too large, resulting in partial structural redundancy, affecting the production cost of the clothing processing equipment.

[0089] Reference Figure 1 , Figure 2 and Figure 8 The air outlet 1013 is arranged on the wall of the first ventilation cavity 102 and close to the edge of the first opening 1011. The air outlet 1013 has a first edge 1313 and a second edge 122 which are arranged opposite to each other in the radial direction of the first opening 1011. The second edge 122 is a part of the edge of the first opening 1011. The first edge 1313 is the edge of the partial air outlet 1013 defined by the corresponding structure of the wall of the first ventilation cavity 102. The first edge 1313 and the second edge 122 jointly define the air outlet 1013.

[0090] In some embodiments, the projection of the first edge 1313 on the plane where the first opening 1011 is located may overlap with the second edge 122 and both overlap with the edge of the first opening 1011 .

[0091] In other embodiments, the first edge 1313 is arranged close to the center of the first opening 1011, that is, the projection of the first edge 1313 on the plane where the first opening 1011 is located is located inside the first opening 1011, so as to reduce the redundant structure on the partial support plate 12131 that cannot provide it with enhanced strength, thereby reducing production costs.

[0092] Among them, the radial distance between the projection of the first edge 1313 on the plane where the first opening 1011 is located and the center of the first opening 1011 is greater than or equal to one eighth of the radius of the first opening 1011, so as to ensure that the rear wall of the first ventilation cavity 102 covers the position corresponding to the center of the first opening 1011, and the support plate 12131 has a structure with a sufficiently large area at the position corresponding to the center of the first opening 1011 for installing the support structure to support the clothing processing drum assembly 2.

[0093] Therefore, when the support plate 12131 needs to assume the function of supporting the clothing processing drum assembly, the corresponding structure of the rear wall of the first ventilation cavity 102 and the center position of the first opening 1011 have sufficient strength to support the clothing processing drum assembly 2, ensuring the stability of the clothing processing drum assembly 2.

[0094] Furthermore, the projection of the first edge 1313 on the plane where the first opening 1011 is located forms a straight line, so as to simplify the structure of the support plate 12131 and facilitate the production and processing of the support plate 12131.

[0095] Alternatively, the projection of the first edge 1313 on the plane where the first opening 1011 is located forms an arc that bends toward the center of the first opening 1011, so as to ensure the connection area between the corresponding structure of the cavity wall of the first ventilation cavity 102 and the support plate body, ensure the strength of the corresponding structure of the rear wall of the first ventilation cavity 102, ensure the ventilation area of ​​the air outlet 1013, and at the same time reduce the materials required for the production of the support plate 12131 and reduce the production cost.

[0096] Furthermore, the projection of the first edge 1313 on the plane where the first opening 1011 is located forms an arc curved toward the center of the first opening 1011 , and the stability of the arch can be utilized to ensure the strength of the corresponding structure of the rear wall of the first ventilation cavity 102 .

[0097] The projection of the second edge 122 on the plane where the first opening 1011 is located forms an arc that bends away from the center of the first opening 1011. In some embodiments, the second edge 122 is a portion of the edge of the first opening 1011, that is, a portion of the arc of the edge of the first opening 1011 forms the second edge 122.

[0098] Reference Figure 1-Figure 9 The cavity wall of the first ventilation cavity 102 includes a supporting wall 1314 arranged opposite to the first opening 1011 and a surrounding wall 1315 extending circumferentially along the first opening 1011. The supporting wall 1314 is the corresponding structure of the rear wall of the first ventilation cavity 102, and the surrounding wall 1315 is the corresponding structure of the side wall of the first ventilation cavity 102.

[0099] In some embodiments, the air flow in the ventilation cavity flows radially toward the first opening 1011. Therefore, the surrounding wall 1315 of the first ventilation cavity 102 is mainly connected to the upstream of the first ventilation cavity 102, and the air outlet 1013 is at least partially arranged on the surrounding wall 1315 to ensure that the air outlet 1013 can stably receive the air flow from the upstream of the first ventilation cavity 102, and ensure that the first ventilation cavity 102 can guide the air flow to the clothing processing cavity 201.

[0100] like Figure 3 and Figure 5 As shown, the surrounding wall 1315 gradually extends outward from the supporting wall 1314 to the first opening 1011, that is, the surrounding wall 1315 is inclined in a direction perpendicular to the plane where the first opening 1011 is located. The inclined surrounding wall 1315 has more stable performance, is conducive to the guidance and dispersion of force, and is more conducive to supporting the clothing processing drum assembly 2.

[0101] Furthermore, the surrounding wall 1315 gradually extends outward from the supporting wall 1314 to the first opening 1011 , which can also reduce the resistance of the airflow in the first ventilation cavity 102 and ensure the air volume entering the interior of the clothing processing cavity 201 .

[0102] like Figure 1 , Figure 2 and Figure 4 As shown, the cavity wall of the first ventilation cavity 102 is also provided with a reinforcing structure 1316. By setting the reinforcing structure 1316, the strength of the supporting surrounding wall 1315 and the supporting wall 1314 can be further improved. When the supporting wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, the supporting wall 1314 has sufficient strength to ensure the stability of the setting of the clothing processing drum assembly 2.

[0103] Specifically, the reinforcement structure 1316 includes a plurality of first reinforcement portions 13161, which are arranged at circumferential intervals on a circle, and each first reinforcement portion 13161 extends radially of the circle, and the center of the circle is the center of the support wall 1314. When the support wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, the support wall 1314 is connected to the clothing processing drum assembly 2 at the center position to support the clothing processing drum assembly 2.

[0104] Therefore, when the center of the support wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, multiple first reinforcement parts 13161 surrounding the center position of the support wall 1314 can radially strengthen the strength of the center position of the support wall 1314, so that the force can be transmitted radially to the outside of the support plate body with higher strength, thereby ensuring the strength and structural stability of the center position of the support wall 1314 and ensuring the stability of the setting of the clothing processing drum assembly 2.

[0105] Reference Figure 1 , Figure 2 and Figure 4 A portion of the first reinforcing portion 13161 is located at the supporting wall 1314 and the other portion extends to the surrounding wall 1315. Thus, the first reinforcing portion 13161 can reinforce the supporting wall 1314 and the surrounding wall 1315 at the same time, making the overall strength of the supporting wall 1314 and the surrounding wall 1315 higher and the structure more stable.

[0106] The first reinforcement portion 13161 connects the support wall 1314 and the surrounding wall 1315 at the same time, so that the support wall 1314 and the surrounding wall 1315 can form a stable integral structure with higher strength. In addition, the first reinforcement portion 13161 is also arranged at the connection between the support wall 1314 and the surrounding wall 1315, which can strengthen the connection between the two and ensure the strength and stability of the connection.

[0107] The reinforcement structure 1316 also includes a second reinforcement portion 13162, which is disposed between at least two adjacent first reinforcement portions 13161, and extends circumferentially along the circumference of the circle. The second reinforcement portion 13162 can reinforce the support wall 1314 in the circumferential direction, so that the force can be dispersed at the second reinforcement portion 13162, thereby preventing the support wall 1314 from being deformed under the action of external force and affecting the stability of the overall setting of the clothing processing equipment.

[0108] The reinforcement structure 1316 also includes a third reinforcement portion 13163, which extends circumferentially along the circumference. The third reinforcement portion 13163 can reinforce the support wall 1314 in the circumferential direction, so that the force can be dispersed at the third reinforcement portion 13163, thereby preventing the support wall 1314 from deforming under the action of external force and affecting the stability of the overall setting of the clothing processing equipment. In addition, the third reinforcement portion 13163 is arranged close to the center of the support wall 1314, which can improve the strength of the center of the support wall 1314, ensure the strength of the connection between the center of the support wall 1314 and the clothing processing drum assembly 2, and ensure that the clothing processing drum assembly 2 can be stably supported and set on the support plate 12131.

[0109] Among them, one end of each first reinforcement part 13161 close to the center of the support wall 1314 is connected to the third reinforcement part 13163 to better achieve force transmission and dispersion.

[0110] Reference Figure 6-Figure 10 The support wall 1314 is provided with a support member 11, and the support member 11 is used to support the laundry processing drum assembly 2 of the laundry processing device. The support member 11 is connected to the laundry processing drum assembly 2, that is, the support wall 1314 is used to support the laundry processing drum assembly 2 of the laundry processing device.

[0111] According to some embodiments of the utility model, the projection of the support member 11 on the support wall 1314 is located inside the support wall 1314 to ensure that the support wall 1314 can cover the center position of the first opening 1011, and the clothing processing barrel can be connected to the support wall 1314 and then be arranged on the support plate 12131 to utilize the high-strength support plate 12131 to support the clothing processing barrel assembly 2 and ensure the stability of the setting of the clothing processing barrel assembly 2.

[0112] When the projections of the support member 11 and the air outlet 1013 in the plane where the support wall 1314 is located overlap, the support plate 12131 structure cannot cover the center position of the first opening 1011. When the support plate 12131 needs to assume the function of supporting the clothing processing barrel assembly, the clothing processing barrel cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing processing barrel assembly 2, which may cause the clothing processing barrel assembly 2 to be unstable.

[0113] Furthermore, when the laundry treatment drum assembly 2 is connected to other structures covering the center of the first through opening 1011, in order to improve the strength of the structure connected to the laundry treatment drum assembly 2, the structure needs to be designed with a reinforcing structure 1316 or a high-strength metal material to ensure the stability of its support for the laundry treatment drum assembly 2, thereby increasing the overall production cost of the laundry treatment device. Therefore, the projections of the support member 11 and the air outlet 1013 in the plane where the support wall 1314 is located do not overlap.

[0114] The support member 11 includes: a bearing seat 111 and a bearing 112. The bearing seat 111 is arranged on the support wall 1314. The bearing seat 111 is fixedly arranged on the support wall 1314 to provide an installation position for the bearing 112, and to limit the bearing 112 to ensure the stability of the bearing 112. The bearing 112 is arranged on the bearing seat 111. The bearing 112 is used to cooperate with the rotating shaft 23 on the clothing treatment drum assembly 2 to support the clothing treatment drum assembly 2. Therefore, the clothing treatment drum assembly 2 can be rotatably connected to the bearing seat 111 through the bearing 112, that is, the clothing treatment drum assembly 2 is supported and arranged on the support wall 1314, and the clothing treatment drum assembly 2 can rotate under the drive of the motor.

[0115] Specifically, the bearing 112 includes an outer bearing and an inner bearing. The inner bearing can be rotatably assembled in the inner hole of the outer bearing. The outer bearing is fixedly connected to the bearing seat 111, and the inner bearing is fixedly connected to the rotating shaft 23 of the clothing processing drum assembly 2, so that the clothing processing drum assembly 2 can rotate relative to the bearing seat 111 and the support wall 1314 fixedly connected to the bearing seat 111, and can be supported on the support wall 1314.

[0116] like Fig.10As shown, the support wall 1314 has a placement recess 1311 on the side facing away from the first opening 1011, and the bearing seat 111 is arranged in the placement recess 1311. By arranging the placement recess 1311 on the support wall 1314, not only can an installation space be provided for the bearing seat 111, but also the matching area between the support wall 1314 and the bearing seat 111 can be increased, so that the arrangement of the bearing seat 111 is more stable. Furthermore, it can also avoid that the arrangement of the bearing seat 111 affects the axial size of the overall clothing processing equipment in the clothing processing drum assembly 2, thereby realizing the miniaturization and lightweight of the clothing processing equipment.

[0117] Among them, the shape of the bearing seat 111 is adapted to the shape of the placing recess 1311, so that the bearing seat 111 can be completely embedded in the placing recess 1311, and the inner wall of the placing recess 1311 is used to limit the bearing seat 111 to ensure the stability of the setting of the bearing seat 111. It can also avoid the placing recess 1311 occupying too much space to affect the space used for ventilation inside the first ventilation cavity 102, and reduce the influence of the setting of the placing recess 1311 on the wind resistance in the first ventilation cavity 102.

[0118] Furthermore, the placement recess 1311 is arranged on the side of the support wall 1314 facing away from the first opening 1011, so that the bearing seat 111 can be arranged outside the ventilation cavity, so that the bearing 112 and the bearing seat 111 do not need to directly contact the airflow in the first ventilation cavity 102, thereby preventing water vapor in the airflow from corroding the bearing 112 or the bearing seat 111 and affecting the service life of the bearing 112 and the bearing seat 111.

[0119] The bottom wall of the recess 1311 is provided with a through hole 1312 to allow the bearing seat 111 or the rotating shaft 23 to pass through, so as to connect the bearing seat 111 arranged on the rear side of the support wall 1314 and the clothing processing drum assembly 2 arranged on the front side of the support wall 1314.

[0120] Reference Fig.10The bearing seat 111 includes a first seat body 1111 and a second seat body 1112. The first seat body 1111 and the second seat body 1112 are arranged relative to each other and define an installation space. The installation space can provide space for the installation of the bearing 112, wherein the bearing 112 is a rolling bearing and is arranged in the installation space. The rolling bearing includes an outer bearing and an inner bearing. The outer bearing is fixedly arranged in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23. The first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing. That is to say, the first seat body 1111 and the second seat body 1112 respectively limit the bearing 112 on both sides of the axial direction of the bearing 112 to ensure the stability of the bearing 112. A limiting step 231 is provided on the rotating shaft 23, and the limiting step 231 stops on one side of the inner ring of the rolling bearing to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing and affecting the stability of the connection of the rotating shaft 23. The inner bearing of the inner ring of the rolling bearing is fixedly connected to the rotating shaft 23 by an interference fit so that the rotating shaft 23 and the clothing processing drum assembly 2 connected to the rotating shaft 23 can rotate relative to the support plate 12131.

[0121] Reference Figure 1-Figure 9 In some embodiments, the clothes processing device further comprises a volute 132, and a portion of the flow passage upstream of the first ventilation chamber 102 is defined by the volute 132 and the support plate 12131. The volute 132 and the support plate 12131 together form an air duct housing assembly connecting the air duct and the inlet of the clothes processing chamber 201.

[0122] Specifically, the support plate 12131 is further provided with a second opening 1012, the second opening 1012 is spaced apart from the first opening 1011, the volute 132 is provided on the support plate 12131 and defines a second ventilation cavity 103 communicating with the second opening 1012 with the support plate 12131, and the air port 1013 communicates with the second ventilation cavity 103 and the first ventilation cavity 102. The airflow in the clothing processing device flows from the second opening 1012 to the first opening 1011, that is, the airflow entering the air duct housing assembly from the second opening 1012 sequentially passes through the second ventilation cavity 103, the air port 1013 and the first ventilation cavity 102 to reach the first opening 1011, and enters the clothing processing cavity 201 through the first opening 1011.

[0123] Since the volute 132 and the support plate 12131 are connected after being formed separately, and the volute 132 does not bear a supporting function, the volute 132 can be made of low-strength and low-priced materials, thereby reducing the production cost of the clothing processing equipment.

[0124] In other embodiments, the flow channel upstream of the first ventilation cavity 102 may also be defined by other structures. For example, the flow channel upstream of the first ventilation cavity 102 may be defined by a mounting seat, and the flow channel connects the outlet of the clothing processing cavity 201 and the air outlet 1013, and may also realize the circulation of the air flow in the dry clothes.

[0125] Combination Figure 4-Figure 9 In the illustrated embodiment, the volute 132 covers the second opening 1012 and the air outlet 1013 to connect the second opening 1012 with the air outlet 1013. The sealing between the volute 132 and the contact portion of the corresponding structure of the cavity wall of the first ventilation cavity 102 is achieved by stacking at least a portion of the volute 132 on the outer side of the cavity wall of the first ventilation cavity 102 to achieve sealing cooperation. By stacking, the contact area between the volute 132 and the corresponding structure of the cavity wall of the first ventilation cavity 102 can be increased, ensuring the sealing effect between the volute 132 and the support plate 12131.

[0126] In some embodiments, the support plate 12131 may be a metal part, so that the support plate 12131 has a higher strength by utilizing a high-strength metal material, thereby having sufficient strength to support the laundry processing drum assembly 2 and to be connected to the laundry processing drum assembly 2 .

[0127] In some embodiments, the volute 132 can be a plastic part to reduce the difficulty of production and processing while utilizing the low density and high strength characteristics of the plastic material to make the volute 132 have sufficient strength, thereby ensuring the stability of the setting of the volute 132 and making the weight of the volute 132 lighter, thereby achieving lightweight clothing processing equipment.

[0128] like Figure 6-Figure 8 As shown, a volute tongue portion 1321 is formed on the volute 132, and the projection of the volute tongue portion 1321 on the plane where the first opening 1011 is located is located between the first opening 1011 and the second opening 1012. The shape and size of the volute tongue portion 1321 can improve the flow characteristics of the airflow and reduce wind resistance, so that the airflow can flow more smoothly from the second opening 1012 to the first opening 1011, reducing noise and vibration.

[0129] Since the structure of the volute tongue portion 1321 is relatively complex, by arranging the volute tongue portion 1321 on the volute 132, the processing difficulty of the support plate 12131 can be reduced, which is conducive to the integral stamping forming of the support plate 12131 and ensures that it can more stably support the clothing processing drum assembly 2.

[0130] In some embodiments, the volute 132 and the cavity wall of the first ventilation cavity 102 are matched at a portion tangent to the first opening 1011 to reduce air flow resistance and ensure ventilation performance in the ventilation cavity.

[0131] According to some embodiments of the utility model, the clothing processing device also includes: an outer cover (not shown in the figure), which is arranged on one side of the support plate 12131 in the thickness direction and covers the cavity wall and the volute 132 of the first ventilation cavity 102 to reduce the noise during the operation of the clothing processing device and realize functions such as heat insulation and noise reduction.

[0132] like Figure 1 and Figure 2 As shown, the outer side of the cavity wall of the first ventilation cavity 102 is provided with a limiting protrusion 1317, which extends along the hole of the air outlet 1013 and stops on one side of the volute 132 to facilitate the assembly of the volute 132, while increasing the sealing area between the volute 132 and the support plate 12131, thereby improving the sealing performance of the ventilation cavity.

[0133] Among them, the outer cover is connected to the support plate 12131 through fasteners, and a fastening hole 13171 is provided on the limiting protrusion 1317. The outer cover is connected to the fastening hole 13171 through the fasteners to set the outer cover on the limiting protrusion 1317, thereby the high-strength support plate 12131 structure can be used to support and connect the outer cover to ensure the stability of the outer cover setting.

[0134] like Figure 5-Figure 8 As shown, the clothing treatment drum assembly 2 comprises: a drum body 211 and an air inlet cover 22, wherein the drum body 211 has a clothing access opening at one axial end and an open opening at the other axial end, wherein the clothing access opening faces the front side of the clothing treatment device, and the user can put clothing into the clothing treatment chamber 201 through the clothing access opening, and the open opening faces the rear side of the clothing treatment device, and airflow can enter the clothing treatment chamber 201 through the open opening to dry the clothing. The air inlet cover 22 covers the open opening to define the clothing treatment chamber 201 with the drum body 211, and the air inlet cover 22 can separate the first ventilation chamber 102 from the clothing treatment chamber 201 on the one hand, to prevent clothing from entering the first ventilation chamber 102 through the open opening, and on the other hand, the air inlet cover 22 provides an installation position for the setting of the rotating shaft 23, and the rotating shaft 23 is arranged on the air inlet cover 22, ensuring that the rotating shaft 23 can stably support the entire clothing treatment drum assembly 2.

[0135] The air inlet cover 22 also has a second extension portion extending in a direction away from the barrel 211. The second extension portion is a hole-free structure. The second extension portion does not correspond to the first opening 1011. The setting of the second extension portion can separate the clothing processing barrel assembly 2 from the support plate 12131 to avoid interference between the clothing processing barrel assembly 2 and the support plate 12131 during rotation.

[0136] The second extending portion is located between the first extending portion 223 and the barrel 211 , and the first extending portion 223 extends in a direction away from the barrel 211 relative to the second extending portion.

[0137] A wind wheel is disposed in the second ventilation cavity 103 opposite to the second opening 1012 , and is used to drive airflow to circulate in the first ventilation cavity 102 , the second ventilation cavity 103 , the air duct and the clothing processing cavity 201 .

[0138] According to some embodiments of the utility model, the clothing processing device further comprises a mounting seat, which defines an air duct to connect the clothing processing chamber 201 and the second opening 1012, and a heating element is arranged in the air duct. During the operation of the clothing processing device, the wet and cold airflow in the clothing processing chamber 201 passes through the air duct defined by the mounting seat, is heated and dehumidified in the air duct, passes through the second opening 1012, and enters the second ventilation chamber 103, the air outlet 1013 and the first ventilation chamber 102 under the drive of the wind wheel, and the dry and hot airflow in the first ventilation chamber 102 enters the clothing processing chamber 201 through the first opening 1011 and the air inlet 2231 of the clothing processing drum assembly 2, and performs drying treatment on the clothing.

[0139] According to some embodiments of the utility model, the clothing processing device further includes: a heat pump system, the heat pump system includes an evaporator, a condenser and a compressor, and the heating element includes an evaporator and a condenser. In the clothing processing chamber 201, the dry hot air passes through the wet clothes, the moisture remaining on the clothes absorbs heat, and the air becomes hot and humid air. The hot and humid air enters the air duct, and the hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is discharged. At this time, the dry cold air continues to be heated and pressurized by the compressor and the evaporator.

[0140] A specific embodiment of the clothes processing device of the present invention is described below with reference to the accompanying drawings.

[0141] like Figure 1-Figure 12 As shown, the clothes processing device includes a mounting seat, a heat pump system, an air duct housing assembly and a clothes processing drum assembly 2.

[0142] The air duct shell assembly includes a separately formed support plate 12131 and a volute 132. The support plate 12131 may be a metal part, so that the support plate 12131 has a higher strength by using a high-strength metal material, so that it has sufficient strength to support the laundry treatment drum assembly 2 and is connected to the laundry treatment drum assembly 2. The volute 132 may be a plastic part, so that the difficulty of production and processing is reduced while using the low-density and high-strength characteristics of the plastic material to make the volute 132 have sufficient strength, ensure the stability of the volute 132 setting, and make the volute 132 lighter, so as to achieve lightweight clothing treatment equipment.

[0143] The support plate 12131 is an integrally stamped part and defines a first ventilation cavity 102. The support plate 12131 includes a support plate body, a surrounding wall 1315 and a support wall 1314. The support plate body is provided with a first opening 1011 and a second opening 1012. The second opening 1012 is arranged at intervals from the first opening 1011. The cavity wall of the first ventilation cavity 102 includes a support wall 1314 arranged opposite to the first opening 1011 and a surrounding wall 1315 extending along the circumference of the first opening 1011. The first opening 1011 and the first ventilation cavity 102 are arranged opposite to and connected to each other in the thickness direction of the support plate 12131. Thus, the support plate 12131 can be integrally stamped from a plate, which simplifies the forming method of the support plate 12131 and reduces the production cost of the support plate 12131. The air outlet 1013 is arranged on the cavity wall of the first ventilation cavity 102 and connects the inside and outside of the first ventilation cavity 102.

[0144] The projection of the air outlet 1013 on the plane where the first through hole 1011 is located is located inside the first through hole 1011 , and the projection area of ​​the air outlet 1013 on the plane where the first through hole 1011 is located is less than half of the area of ​​the first through hole 1011 .

[0145] The projection of the air outlet 1013 on the plane where the first opening 1011 is located extends along the first direction, and the second direction is the radial direction of the first opening 1011 and is perpendicular to the first direction. Since the first opening 1011 is formed as a circular hole, the first opening 1011 and the first ventilation cavity 102 are arranged opposite to each other in the thickness direction of the support plate 12131, so the intersection line of the cavity wall of the first ventilation cavity 102 and the plane where the first opening 1011 is located is arranged around the first opening 1011. The cavity wall of the first ventilation cavity 102 includes a side wall and a rear wall, the side wall is arranged around the rear wall and is connected to the edge of the first opening 1011, the air outlet 1013 includes a part arranged on the side wall of the first ventilation cavity 102 and a part arranged on the rear wall of the first ventilation cavity 102, the part of the air outlet 1013 arranged on the side wall of the first ventilation cavity 102 mainly affects the size of the air outlet 1013 in the first direction, and the part of the air outlet 1013 arranged on the rear wall of the first ventilation cavity 102 mainly affects the size of the air outlet 1013 in the second direction.

[0146] The dimension X of the projection of the air outlet 1013 in the first direction is 0.2-0.8 times the diameter of the first opening 1011 , and the dimension Y of the projection of the air outlet 1013 in the second direction is 0.1-0.4 times the diameter of the first opening 1011 .

[0147] The air outlet 1013 is arranged on the wall of the first ventilation cavity 102 and close to the edge of the first opening 1011. The air outlet 1013 has a first edge 1313 and a second edge 122 which are relatively arranged in the radial direction of the first opening 1011. The second edge 122 is a part of the edge of the first opening 1011. The first edge 1313 is the edge of the partial air outlet 1013 defined by the corresponding structure of the wall of the first ventilation cavity 102. The first edge 1313 and the second edge 122 jointly define the air outlet 1013.

[0148] Among them, the radial distance between the projection of the first edge 1313 on the plane where the first opening 1011 is located and the center of the first opening 1011 is greater than or equal to one eighth of the radius of the first opening 1011, and the projection of the first edge 1313 on the plane where the first opening 1011 is located forms a straight line, so as to simplify the structure of the support plate 12131 and facilitate the production and processing of the support plate 12131.

[0149] Alternatively, the projection of the first edge 1313 on the plane where the first opening 1011 is located forms an arc that bends toward the center of the first opening 1011, so as to ensure the connection area between the corresponding structure of the cavity wall of the first ventilation cavity 102 and the support plate body, ensure the strength of the corresponding structure of the rear wall of the first ventilation cavity 102, ensure the ventilation area of ​​the air outlet 1013, and at the same time reduce the materials required for the production of the support plate 12131 and reduce the production cost.

[0150] Furthermore, the projection of the first edge 1313 on the plane where the first opening 1011 is located forms an arc curved toward the center of the first opening 1011 , and the stability of the arch can be utilized to ensure the strength of the corresponding structure of the rear wall of the first ventilation cavity 102 .

[0151] Part of the flow passage upstream of the first ventilation cavity 102 is defined by the volute 132 and the support plate 12131. The volute 132 covers the second opening 1012 and the air outlet 1013 to connect the second opening 1012 with the air outlet 1013. The volute 132 is disposed on the support plate 12131 and defines a second ventilation cavity 103 connected with the second opening 1012 with the support plate 12131, and the air outlet 1013 connects the second ventilation cavity 103 with the first ventilation cavity 102. The airflow in the clothing processing device flows from the second opening 1012 to the first opening 1011, that is, the airflow entering the air duct shell assembly from the second opening 1012 sequentially passes through the second ventilation cavity 103, the air outlet 1013 and the first ventilation cavity 102 to reach the first opening 1011, and enters the clothing processing cavity 201 through the first opening 1011.

[0152] The seal between the contact part of the volute 132 and the corresponding structure of the cavity wall of the first ventilation chamber 102 is achieved by stacking at least a part of the volute 132 on the outside of the cavity wall of the first ventilation chamber 102 to achieve sealing cooperation. Through the stacking arrangement, the contact area between the volute 132 and the corresponding structure of the cavity wall of the first ventilation chamber 102 can be increased, thereby ensuring the sealing effect between the volute 132 and the support plate 12131.

[0153] A volute tongue portion 1321 is formed on the volute 132, and the projection of the volute tongue portion 1321 on the plane where the first opening 1011 is located is located between the first opening 1011 and the second opening 1012. The shape and size of the volute tongue portion 1321 can improve the flow characteristics of the airflow and reduce wind resistance, so that the airflow can flow more smoothly from the second opening 1012 to the first opening 1011, reducing noise and vibration.

[0154] Since the structure of the volute tongue portion 1321 is relatively complex, by arranging the volute tongue portion 1321 on the volute 132, the processing difficulty of the support plate 12131 can be reduced, which is conducive to the integral stamping forming of the support plate 12131 and ensures that it can more stably support the clothing processing drum assembly 2.

[0155] In some embodiments, the volute 132 and the cavity wall of the first ventilation cavity 102 are matched at a portion tangent to the first opening 1011 to reduce air flow resistance and ensure ventilation performance in the ventilation cavity.

[0156] The supporting wall 1314 and the surrounding wall 1315 jointly define the first ventilation cavity 102. The surrounding wall 1315 gradually extends outward from the supporting wall 1314 to the first opening 1011. The cavity wall of the first ventilation cavity 102 is also provided with a reinforcing structure 1316. Through the setting of the reinforcing structure 1316, the strength of the supporting surrounding wall 1315 and the supporting wall 1314 can be further improved. When the supporting wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, the supporting wall 1314 has sufficient strength to ensure the stability of the setting of the clothing processing drum assembly 2.

[0157] The reinforcement structure 1316 includes a plurality of first reinforcement portions 13161, which are arranged at intervals in the circumferential direction of a circle, and each first reinforcement portion 13161 extends radially of the circle, and the center of the circle is the center of the support wall 1314. When the support wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, the support wall 1314 is connected to the clothing processing drum assembly 2 at the center position to support the clothing processing drum assembly 2.

[0158] Therefore, when the center of the support wall 1314 needs to assume the function of supporting the clothing processing drum assembly 2, multiple first reinforcement parts 13161 surrounding the center position of the support wall 1314 can radially strengthen the strength of the center position of the support wall 1314, so that the force can be transmitted radially to the outside of the support plate body with higher strength, thereby ensuring the strength and structural stability of the center position of the support wall 1314 and ensuring the stability of the setting of the clothing processing drum assembly 2.

[0159] A portion of the first reinforcing portion 13161 is located at the supporting wall 1314 and another portion extends to the surrounding wall 1315 , thereby the first reinforcing portion 13161 can reinforce the supporting wall 1314 and the surrounding wall 1315 at the same time, making the overall strength of the supporting wall 1314 and the surrounding wall 1315 higher and the structure more stable.

[0160] The first reinforcement portion 13161 connects the support wall 1314 and the surrounding wall 1315 at the same time, so that the support wall 1314 and the surrounding wall 1315 can form a stable integral structure with higher strength. In addition, the first reinforcement portion 13161 is also arranged at the connection between the support wall 1314 and the surrounding wall 1315, which can strengthen the connection between the two and ensure the strength and stability of the connection.

[0161] The reinforcement structure 1316 also includes a second reinforcement portion 13162, which is disposed between at least two adjacent first reinforcement portions 13161, and extends circumferentially along the circumference of the circle. The second reinforcement portion 13162 can reinforce the support wall 1314 in the circumferential direction so that the force can be dispersed at the second reinforcement portion 13162, thereby preventing the support wall 1314 from deforming under the action of external force and affecting the stability of the overall setting of the air duct shell assembly.

[0162] The reinforcement structure 1316 also includes a third reinforcement portion 13163, which extends circumferentially along the circumference of the circle. The third reinforcement portion 13163 can reinforce the support wall 1314 in the circumferential direction, so that the force can be dispersed at the third reinforcement portion 13163, thereby preventing the support wall 1314 from deforming under the action of external force and affecting the stability of the overall setting of the air duct shell assembly. In addition, the third reinforcement portion 13163 is arranged close to the center of the support wall 1314, which can improve the strength of the center of the support wall 1314, ensure the strength of the connection between the center of the support wall 1314 and the clothing processing drum assembly 2, and ensure that the clothing processing drum assembly 2 can be stably supported and set on the support plate 12131.

[0163] Among them, one end of each first reinforcement part 13161 close to the center of the support wall 1314 is connected to the third reinforcement part 13163 to better achieve force transmission and dispersion.

[0164] The air duct shell assembly also includes: an outer cover, which is arranged on one side of the support plate 12131 in the thickness direction and covers the cavity wall and the volute 132 of the first ventilation cavity 102 to reduce the noise during the operation of the clothing processing equipment and achieve functions such as heat insulation and noise reduction.

[0165] like Figure 1 and Figure 2 As shown, the outer side of the cavity wall of the first ventilation cavity 102 is provided with a limiting protrusion 1317, which extends along the hole of the air outlet 1013 and stops on one side of the volute 132 to facilitate the assembly of the volute 132, while increasing the sealing area between the volute 132 and the support plate 12131, thereby improving the sealing performance of the ventilation cavity.

[0166] Among them, the outer cover is connected to the support plate 12131 through fasteners, and a fastening hole 13171 is provided on the limiting protrusion 1317. The outer cover is connected to the fastening hole 13171 through the fasteners to set the outer cover on the limiting protrusion 1317, thereby the high-strength support plate 12131 structure can be used to support and connect the outer cover to ensure the stability of the outer cover setting.

[0167] A support member 11 is provided on the support wall 1314, and the support member 11 is used to support the laundry processing drum assembly 2 of the laundry processing device. The support member 11 is connected to the laundry processing drum assembly 2, that is, the support wall 1314 is used to support the laundry processing drum assembly 2 of the laundry processing device.

[0168] According to some embodiments of the utility model, the projection of the support member 11 on the support wall 1314 is located inside the support wall 1314 to ensure that the support wall 1314 can cover the center position of the first opening 1011, and the clothing processing barrel can be connected to the support wall 1314 and then be arranged on the support plate 12131 to utilize the high-strength support plate 12131 to support the clothing processing barrel assembly 2 and ensure the stability of the setting of the clothing processing barrel assembly 2.

[0169] When the projections of the support member 11 and the air outlet 1013 in the plane where the support wall 1314 is located overlap, the support plate 12131 structure cannot cover the center position of the first opening 1011. When the air duct shell assembly needs to assume the function of supporting the clothing processing barrel assembly, the clothing processing barrel cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing processing barrel assembly 2, which may cause the clothing processing barrel assembly 2 to be unstable.

[0170] Furthermore, when the laundry treatment drum assembly 2 is connected to other structures covering the center of the first through-port 1011, in order to improve the strength of the structure connected to the laundry treatment drum assembly 2, the structure needs to be designed with a reinforcing structure 1316 or a high-strength metal material to ensure the stability of its support for the laundry treatment drum assembly 2, thereby increasing the overall production cost of the air duct housing assembly. Therefore, the projections of the support member 11 and the air outlet 1013 in the plane where the support wall 1314 is located do not overlap.

[0171] The support member 11 includes: a bearing seat 111 and a bearing 112. The bearing seat 111 is arranged on the support wall 1314. The bearing seat 111 is fixedly arranged on the support wall 1314 to provide an installation position for the bearing 112, and to limit the bearing 112 to ensure the stability of the bearing 112. The bearing 112 is arranged on the bearing seat 111. The bearing 112 is used to cooperate with the rotating shaft 23 on the clothing treatment drum assembly 2 to support the clothing treatment drum assembly 2. Therefore, the clothing treatment drum assembly 2 can be rotatably connected to the bearing seat 111 through the bearing 112, that is, the clothing treatment drum assembly 2 is supported and arranged on the support wall 1314, and the clothing treatment drum assembly 2 can rotate under the drive of the motor.

[0172] Specifically, the bearing 112 includes an outer bearing and an inner bearing. The inner bearing can be rotatably assembled in the inner hole of the outer bearing. The outer bearing is fixedly connected to the bearing seat 111, and the inner bearing is fixedly connected to the rotating shaft 23 of the clothing processing drum assembly 2, so that the clothing processing drum assembly 2 can rotate relative to the bearing seat 111 and the support wall 1314 fixedly connected to the bearing seat 111, and can be supported on the support wall 1314.

[0173] like Fig.10 As shown, the support wall 1314 has a placement recess 1311 on the side facing away from the first opening 1011, and the bearing seat 111 is arranged in the placement recess 1311. By arranging the placement recess 1311 on the support wall 1314, not only can an installation space be provided for the bearing seat 111, but also the matching area between the support wall 1314 and the bearing seat 111 can be increased, so that the arrangement of the bearing seat 111 is more stable. Furthermore, it can also avoid that the arrangement of the bearing seat 111 affects the axial size of the overall clothing processing equipment in the clothing processing drum assembly 2, thereby realizing the miniaturization and lightweight of the clothing processing equipment.

[0174] Among them, the shape of the bearing seat 111 is adapted to the shape of the placing recess 1311, so that the bearing seat 111 can be completely embedded in the placing recess 1311, and the inner wall of the placing recess 1311 is used to limit the bearing seat 111 to ensure the stability of the setting of the bearing seat 111. It can also avoid the placing recess 1311 occupying too much space to affect the space used for ventilation inside the first ventilation cavity 102, and reduce the influence of the setting of the placing recess 1311 on the wind resistance in the first ventilation cavity 102.

[0175] Furthermore, the placement recess 1311 is arranged on the side of the support wall 1314 facing away from the first opening 1011, so that the bearing seat 111 can be arranged outside the ventilation cavity, so that the bearing 112 and the bearing seat 111 do not need to directly contact the airflow in the first ventilation cavity 102, thereby preventing water vapor in the airflow from corroding the bearing 112 or the bearing seat 111 and affecting the service life of the bearing 112 and the bearing seat 111.

[0176] The bottom wall of the recess 1311 is provided with a through hole 1312 to allow the bearing seat 111 or the rotating shaft 23 to pass through, so as to connect the bearing seat 111 arranged on the rear side of the support wall 1314 and the clothing processing drum assembly 2 arranged on the front side of the support wall 1314.

[0177] Reference Fig.10 The bearing seat 111 includes a first seat body 1111 and a second seat body 1112. The first seat body 1111 and the second seat body 1112 are arranged relative to each other and define an installation space. The installation space can provide space for the installation of the bearing 112, wherein the bearing 112 is a rolling bearing and is arranged in the installation space. The rolling bearing includes an outer bearing and an inner bearing. The outer bearing is fixedly arranged in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23. The first seat body 1111 and the second seat body 1112 are stopped at opposite sides of the outer ring of the rolling bearing. That is to say, the first seat body 1111 and the second seat body 1112 respectively limit the bearing 112 on both sides of the axial direction of the bearing 112 to ensure the stability of the bearing 112. A limiting step 231 is provided on the rotating shaft 23, and the limiting step 231 stops on one side of the inner ring of the rolling bearing to prevent the rotating shaft 23 from moving in the axial direction relative to the rolling bearing, affecting the stability of the connection of the rotating shaft 23. The inner bearing of the inner ring of the rolling bearing is fixedly connected to the rotating shaft 23 by an interference fit, so that the rotating shaft 23 and the clothing processing drum assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct shell assembly.

[0178] The clothing processing drum assembly 2 defines a clothing processing chamber 201, which is used to accommodate clothing to be processed. A portion of the clothing processing drum assembly 2 extends from the first opening 1011 into the first ventilation chamber 102. Thus, the clothing processing drum assembly 2 can be designed to be deeper without changing the external dimensions of the clothing processing device, thereby increasing the capacity of the clothing processing chamber 201. The clothing processing device can process more and larger clothing at the same time, thereby improving the user experience.

[0179] The clothes processing drum assembly 2 has an air inlet 2231, which can directly connect the first ventilation cavity 102 and the clothes processing cavity 201. During the flow of air, the air in the first ventilation cavity 102 can directly enter the clothes processing cavity 201 through the air inlet 2231. This reduces the air flow resistance and reduces the production cost of the clothes processing device.

[0180] The clothing treatment drum assembly 2 is rotatably supported and arranged on the air duct shell assembly through the rotating shaft 23. The clothing treatment drum assembly 2 includes: a drum body 211 and an air inlet cover 22. The drum body 211 has a clothing access opening at one axial end and an open opening at the other axial end, wherein the clothing access opening faces the front side of the clothing treatment device, and the user can put clothing into the clothing treatment chamber 201 through the clothing access opening, and the open opening faces the rear side of the clothing treatment device, and the airflow can enter the cavity defined by the drum body 211 through the open opening to dry the clothing. The cavity defined by the drum body 211 is the part of the clothing treatment chamber 201 mainly used to accommodate clothing. The air inlet cover 22 covers the open opening to define the clothing treatment chamber 201 together with the drum body 211. On the one hand, the air inlet cover 22 can separate the first ventilation chamber 102 from the clothing treatment chamber 201 to prevent clothing from entering the first ventilation chamber 102 through the open opening. On the other hand, the air inlet cover 22 provides an installation position for the setting of the rotating shaft 23, and the rotating shaft 23 is arranged on the air inlet cover 22.

[0181] The air inlet portion 2231 is arranged around the rotating shaft 23 to ensure the strength of the connection between the rotating shaft 23 and the air inlet cover 22, to avoid the setting of the air inlet portion 2231 affecting the connection between the rotating shaft 23 and the air inlet cover 22, and to avoid the setting of the rotating shaft 23 affecting the air inlet area of ​​the air inlet portion 2231, thereby ensuring the air intake volume of the air inlet portion 2231.

[0182] The middle part of the air inlet cover 22 extends in the direction close to the clothing loading and unloading port to form a accommodating recess 221 on the outer surface of the air inlet cover 22. The rotating shaft 23 is arranged on the bottom wall of the accommodating recess 221 and protrudes from the plane where the opening of the accommodating recess 221 is located. The opening of the accommodating recess 221 provides an installation space for the setting of the rotating shaft 23 and the connecting structure between the rotating shaft 23 and the air inlet cover 22, thereby avoiding interference with the structure on the rear side and affecting the normal operation and rotation of the clothing processing drum assembly 2.

[0183] The rotating shaft 23 protrudes from the plane where the opening of the accommodating recess 221 is located, so as to be rotatably connected to the structure located behind the clothing processing drum assembly 2, so that the clothing processing drum assembly 2 as a whole can be supported and arranged on the air duct shell assembly.

[0184] The air inlet cover 22 has a second extension portion and a first extension portion 223 extending in a direction away from the cylinder 211 . The first extension portion 223 extends into the first ventilation cavity 102 . The second extension portion is a non-porous structure, wherein the second extension portion is located between the first extension portion 223 and the cylinder 211 .

[0185] In some embodiments, a wind wheel arranged opposite to the second opening 1012 is provided in the second ventilation cavity 103 of the air duct housing assembly, and the clothing processing device further includes a mounting seat, which defines an air duct to connect the clothing processing cavity 201 and the second opening 1012 .

[0186] A heating element is provided in the air duct. During the operation of the clothing processing device, the wet and cold airflow in the clothing processing chamber 201 passes through the air duct defined by the mounting seat, is heated and dehumidified in the air duct, passes through the second opening 1012, and enters the first ventilation chamber 102 and the second ventilation chamber 103 defined by the air duct shell assembly under the drive of the wind wheel. The dry and hot airflow in the first ventilation chamber 102 then enters the clothing processing chamber 201 through the air inlet portion 2231 of the clothing processing drum assembly 2 to dry the clothing.

[0187] The clothing treatment device also includes: a heat pump system, the heat pump system includes an evaporator, a condenser and a compressor, and the heating element includes an evaporator and a condenser. In the clothing treatment chamber 201, the dry hot air passes through the wet clothes, the moisture remaining on the clothes absorbs heat, and the air becomes hot and humid air. The hot and humid air enters the air duct, and the hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is discharged. At this time, the dry cold air continues to be heated and pressurized by the compressor and evaporator.

[0188] A sealing ring 3 is provided between the air inlet cover 22 and the air duct shell assembly, and the sealing ring 3 surrounds the outside of the first opening 1011, that is, also surrounds the outside of the air inlet portion 2231, to achieve sealing between the air duct shell assembly and the clothing processing drum assembly 2, the sealing ring 3 is fixed on the air duct shell assembly, and an annular stop protrusion 225 is provided on the air inlet cover 22 to flexibly cooperate with the sealing ring 3.

[0189] Reference Figure 7-Figure 9 The support plate 12131 includes a limiting flange 121. The edge of the first opening 1011 has a limiting flange 121 extending toward the direction close to the cylinder 211. The sealing ring 3 is sleeved on the outside of the limiting flange 121. The limiting flange 121 can limit the sealing ring 3 and provide an installation position for the setting of the sealing ring 3, thereby avoiding the movement of the sealing ring 3 and affecting the sealing performance.
