[0002] This application is based on and claims priority to Chinese patent applications No. 202421242181.4 and 202410705185.X, filed on May 31, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing equipment technology, and in particular to a clothing processing device. Background Technology

[0004] In order to simplify the manufacturing process, the air duct shell assembly of the clothing processing equipment disclosed in the related technology is made into two parts in the thickness direction, namely the plate part and the shell part, which are formed separately and then connected by fasteners to jointly define the ventilation cavity. Since the shell part and the plate part are connected by fasteners, the installation cost of the air duct shell assembly is high. The sealing performance at the connection between the two parts is affected by the installation process, resulting in poor sealing of the ventilation cavity. This affects the air volume entering the clothing processing cavity of the clothing processing equipment. Furthermore, the depth and volume of the clothing processing cavity are limited by the space in front of the support plate, and the clothing processing cavity cannot accommodate more clothes, affecting the user experience.

Detailed Implementation

[0061] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0062] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0063] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0064] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0065] To simplify manufacturing, traditional garment processing equipment often uses two separate parts in the thickness direction—the plate and the shell—for the duct housing assembly. These parts are then connected by fasteners to define the ventilation cavity. Because the shell and plate are connected by fasteners, the installation cost of the garment processing equipment is high. The sealing performance at the connection point is affected by the installation process, resulting in poor sealing of the ventilation cavity. This, in turn, affects the airflow entering the garment processing cavity. Furthermore, the depth and volume of the garment processing cavity are limited by the space in front of the support plate, preventing the cavity from accommodating more garments and impacting the user experience.

[0066] Therefore, this application embodiment designs an integrally formed support plate 12131 that defines a portion of the ventilation cavity, and a portion of the clothing processing cavity extends into the ventilation cavity defined by the support plate 12131. Since the support plate 12131 is integrally formed, the assembly cost is reduced, the sealing performance of the ventilation cavity defined by it is better, and the clothing processing cavity can extend into the first ventilation cavity, increasing the depth of the clothing processing cavity and increasing the capacity of the clothing processing cavity without changing the overall thickness of the clothing processing equipment.

[0067] The garment processing apparatus according to an embodiment of the present application is described below with reference to Figures 1-12.

[0068] The clothing processing device according to the embodiments of this application may include: clothing processing tube assembly 2 and support plate 12131.

[0069] In this embodiment, the support plate 12131 is integrally formed to form a first ventilation cavity 102 with a first opening 1011. 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 in the prior art that only includes a single plane, the support plate 12131 in this embodiment defines the first ventilation cavity 102 with a first opening 1011. The first ventilation cavity 102 is formed as a part of the ventilation cavity that connects the air outlet of the clothing processing cavity 201 and the air inlet of the clothing processing cavity 201, which is close to the air inlet of the clothing processing cavity 201.

[0070] 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 garment processing equipment is reduced.

[0071] 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 arranged opposite to each other and connected in the thickness direction of the support plate 12131. Thus, the support plate 12131 can be integrally stamped from sheet metal, which simplifies the forming method of the support plate 12131 and reduces the production cost of the support plate 12131.

[0072] The garment processing cylinder defines a garment processing chamber 201 and has an air inlet 2231. The air inlet 2231 connects the first ventilation chamber 102 and the garment processing chamber 201. Airflow only needs to pass through the air inlet 2231 to enter the garment processing chamber 201 from the first ventilation chamber 102, which greatly reduces the wind resistance during the flow of air into the garment processing chamber 201. At least part of the structure of the garment processing cylinder assembly 2 can extend into the first ventilation chamber 102 through the first port 1011, which increases the capacity of the garment processing chamber 201 without changing the overall thickness of the garment processing equipment. The garment processing chamber 201 can hold more clothes and improve the user experience.

[0073] According to the clothing processing device of the present application embodiment, the clothing processing device adopts an integrally formed support plate 12131, which reduces the assembly cost, improves the sealing performance of the gas flow channel, and the clothing processing cavity can extend into the first ventilation cavity 102, increasing the depth of the clothing processing cavity 201 and the capacity of the clothing processing cavity 201 without changing the overall thickness of the clothing processing device.

[0074] As shown in Figures 9-12, the garment processing tube assembly 2 has a first extension 223. The first extension 223 extends from the first opening 1011 into the first ventilation cavity 102 and defines a portion of the garment processing cavity 201. The first extension 223 and the portion of the garment processing cavity 201 defined by the first extension 223 can increase the capacity of the garment processing cavity 201. An air inlet 2231 is provided on the first extension 223 so that the air inlet 2231 can directly connect the first ventilation cavity 12 and the garment processing cavity 201.

[0075] Furthermore, the support plate 12131 is provided with a first opening 1011 and an air passage 1013. In the first ventilation cavity 102, the airflow flows from the air passage 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 passage 1013 is connected to the air outlet of the clothing processing cavity 201.

[0076] An air vent 1013 is located on the cavity wall of the first ventilation chamber 102 and connects the first ventilation chamber 102 and the air duct. The air duct connecting the air outlet of the garment processing chamber 201 and the air vent 1013 can be defined by other structures themselves or by other structures and the support plate 12131. The two can be made of different materials. The support plate 12131 can be made of a high-strength and heavy material, while other structures can be made of relatively low-strength, low-density and inexpensive materials to reduce the production cost of the garment processing components and achieve lightweighting of the garment processing equipment.

[0077] Referring to Figures 1-9, the projection of the cavity wall of the first ventilation cavity 102 onto the plane of the first opening 1011 is located within the first opening 1011, so that the support plate 12131 can be integrally stamped from sheet metal. The material on the sheet metal before stamping the support plate 12131 at the position corresponding to the first opening 1011 is stamped to form the structure corresponding to the cavity wall of the first ventilation cavity 102.

[0078] Since the air vent 1013 is located on the cavity wall of the first ventilation cavity 102, the projection of the cavity wall of the first ventilation cavity 102 in the plane where the first opening 1011 is located is inside the first opening 1011. Therefore, the projection of the air vent 1013 in the plane where the first opening 1011 is located is inside the first opening 1011.

[0079] Referring to the embodiments shown in Figures 1-9, the projected area of ​​the air vent 1013 in the plane where the first opening 1011 is located is less than half the area of ​​the first opening 1011.

[0080] To ensure the sealing performance of the ventilation cavity connecting the inlet and outlet of the garment processing cavity 201, a structure needs to be designed to cover the air vent 1013. If the air vent 1013 is designed to be too large, it will affect the production cost of the structure covering the air vent 1013 and make the assembly and sealing cost between the structure and the support plate 12131 higher.

[0081] Furthermore, when the projected area of ​​the air vent 1013 in the plane where the first opening 1011 is located is greater than half the area of ​​the first opening 1011, the air vent 1013 will cover the center position of the first opening 1011. In other words, the structure of the support plate 12131 cannot cover the center position of the first opening 1011. When the support plate 12131 needs to support the clothing processing drum assembly, the clothing processing drum cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing processing drum assembly 2, which may lead to the instability of the clothing processing drum assembly 2.

[0082] Furthermore, when the garment handling tube assembly 2 is connected to other structures covering the center of the first opening 1011, in order to improve the strength of the structure connected to the garment handling tube assembly 2, this part of the structure needs to be designed with a reinforcing structure 1316 or use high-strength metal materials to ensure its support stability for the garment handling tube assembly 2, which leads to an increase in the overall production cost of the garment handling equipment.

[0083] Referring to Figure 2, the projection of the air vent 1013 onto the plane containing the first opening 1011 extends along a first direction, and the second direction is radial to the first opening 1011 and perpendicular to the first direction. Since the first opening 1011 is formed as a circular hole, and the first opening 1011 and the first ventilation cavity 102 are disposed opposite each other in the thickness direction of the support plate 12131, the intersection line of the cavity wall of the first ventilation cavity 102 and the plane containing the first opening 1011 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 connected to the edge of the first opening 1011. The air passage 1013 includes a portion disposed on the side wall of the first ventilation cavity 102 and a portion disposed on the rear wall of the first ventilation cavity 102. The portion of the air passage 1013 disposed on the side wall of the first ventilation cavity 102 mainly affects the size of the air passage 1013 in the first direction, and the portion of the air passage 1013 disposed on the rear wall of the first ventilation cavity 102 mainly affects the size of the air passage 1013 in the second direction.

[0084] Wherein, the size X of the projection of the air vent 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 portion of the air vent 1013 located 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 size of the projection of the air vent 1013 in the first direction is less than 0.2 times the diameter of the first opening 1011, the opening area of ​​the air vent 1013 is too small, which affects the ventilation performance at the air vent 1013, and thus affects the drying performance of the clothing processing equipment.

[0085] When the projection of the air vent 1013 in the first direction is greater than 0.8 times the diameter of the first opening 1011, the area of ​​the air vent 1013 on the side wall of the first ventilation cavity 102 becomes too large, affecting the connection length between the corresponding structure of the cavity wall of the first ventilation cavity 102 and the main body of the support plate 12131, and thus affecting 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, resulting in low overall stability of the clothing processing equipment.

[0086] The projection of the air vent 1013 in the second direction has a dimension Y that is 0.1-0.4 times the diameter of the first opening 1011. When the projection of the air vent 1013 in the second direction is greater than 0.4 times the diameter of the first opening 1011, the air vent 1013 will be close to or cover the center of the first opening 1011. As a result, the structure of the support plate 12131 cannot cover the center or the area around the center of the first opening 1011. When the support plate 12131 needs to support the clothing handling drum assembly, the support plate 12131 cannot be equipped with a bearing seat 111 or other structures at the corresponding position of the center of the first opening 1011 for connection with the clothing handling drum assembly 2. Therefore, the clothing handling drum cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing handling drum assembly 2, resulting in the unstable setting of the clothing handling drum assembly 2.

[0087] When the projection of the air vent 1013 in the second direction is less than 0.1, it will result in the air vent 1013 having too small an opening area, affecting the ventilation performance at the air vent 1013. It will also result in the support plate 12131 covering an area that is too large, with some structural redundancy, affecting the production cost of the clothing processing equipment.

[0088] Referring to Figures 1, 2, and 8, the air vent 1013 is disposed on the wall of the first ventilation cavity 102 and is located near the edge of the first opening 1011. The air vent 1013 has a first edge 1313 and a second edge 122 that are radially opposite to each other in the first opening 1011. The second edge 122 is a part of the edge of the first opening 1011, and the first edge 1313 is the edge of the portion of the air vent 1013 defined by the corresponding structure of the wall of the first ventilation cavity 102. The first edge 1313 and the second edge 122 together define the air vent 1013.

[0089] In some embodiments, the projection of the first edge 1313 onto the plane where the first opening 1011 is located can coincide with the second edge 122 and both coincide with the edge of the first opening 1011.

[0090] In other embodiments, the first edge 1313 is located 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 inside the first opening 1011, so as to reduce the redundant structure on some support plates 12131 that cannot provide strength enhancement and reduce production costs.

[0091] Wherein, the radial distance between the projection of the first edge 1313 onto 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 sufficiently large area near the position corresponding to the center of the first opening 1011 for installing the support structure to support the clothing handling tube assembly 2.

[0092] Therefore, when the support plate 12131 needs to support the clothing handling 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 handling drum assembly 2, thus ensuring the stability of the clothing handling drum assembly 2.

[0093] Furthermore, the projection of the first edge 1313 onto the plane where the first opening 1011 is located forms a straight line, thereby simplifying the structure of the support plate 12131 and facilitating its production and processing.

[0094] Alternatively, the projection of the first edge 1313 onto the plane where the first opening 1011 is located forms an arc that curves toward the center of the first opening 1011. This ensures the connection area between the corresponding structure of the first ventilation cavity 102 wall and the support plate body, the strength of the corresponding structure of the rear wall of the first ventilation cavity 102, and the ventilation area of ​​the air outlet 1013, while reducing the material required for the production of the support plate 12131 and lowering production costs.

[0095] Furthermore, the projection of the first edge 1313 onto the plane where the first opening 1011 is located forms an arc that curves toward the center of the first opening 1011. The stability of the arch shape can also be utilized to ensure the strength of the structure corresponding to the rear wall of the first ventilation cavity 102.

[0096] The projection of the second edge 122 onto the plane where the first opening 1011 is located forms an arc that curves away from the center of the first opening 1011. In some embodiments, the second edge 122 is a part of the edge of the first opening 1011, that is, a part of the arc of the edge of the first opening 1011 is formed as the second edge 122.

[0097] Referring to Figures 1-9, the cavity wall of the first ventilation cavity 102 includes a support wall 1314 disposed opposite to the first opening 1011 and a surrounding wall 1315 extending circumferentially along the first opening 1011. The support 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.

[0098] In some embodiments, the airflow in the ventilation cavity flows radially toward the first opening 1011. Therefore, the enclosure 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 disposed in the enclosure wall 1315 to ensure that the air outlet 1013 can stably receive the airflow from the upstream of the first ventilation cavity 102 and to ensure that the first ventilation cavity 102 can guide the airflow to the clothing processing cavity 201.

[0099] As shown in Figures 3 and 5, the enclosure 1315 gradually extends outward from the support wall 1314 to the first opening 1011. That is to say, the enclosure 1315 is inclined in the direction perpendicular to the plane where the first opening 1011 is located. The inclined enclosure 1315 has more stable performance, which is conducive to the guidance and dispersion of force and more conducive to supporting the clothing handling tube assembly 2.

[0100] Furthermore, the enclosure 1315 gradually extends outward from the support wall 1314 to the first opening 1011, which can also reduce the airflow resistance in the first ventilation cavity 102 and ensure the airflow entering the clothing processing cavity 201.

[0101] As shown in Figures 1, 2 and 4, 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 wall 1315 and the supporting wall 1314 can be further improved. When the supporting wall 1314 needs to bear the function of supporting the clothing handling tube assembly 2, the supporting wall 1314 has sufficient strength to ensure the stability of the clothing handling tube assembly 2.

[0102] Specifically, the reinforcing structure 1316 includes a plurality of first reinforcing parts 13161, which are arranged circumferentially at intervals on a circumference, and each first reinforcing part 13161 extends radially on the circumference. The center of the circumference is the center of the support wall 1314. When the support wall 1314 needs to bear the function of supporting the clothing handling tube assembly 2, the center position of the support wall 1314 is connected to the clothing handling tube assembly 2 to support the clothing handling tube assembly 2.

[0103] Therefore, when the center of the support wall 1314 needs to support the clothing handling tube assembly 2, the multiple first reinforcing parts 13161 surrounding the center of the support wall 1314 can strengthen the strength of the center of the support wall 1314 in the radial direction, so that the force can be transmitted radially to the support plate body with higher strength, ensuring the strength of the center of the support wall 1314 and the stability of the structure, and ensuring the stability of the clothing handling tube assembly 2.

[0104] Referring to Figures 1, 2 and 4, a portion of the first reinforcing part 13161 is located on the supporting wall 1314 and another portion extends to the enclosure wall 1315. Thus, the first reinforcing part 13161 can simultaneously reinforce the supporting wall 1314 and the enclosure wall 1315, making the overall strength of the supporting wall 1314 and the enclosure wall 1315 higher and the structure more stable.

[0105] The first reinforcing part 13161 connects the supporting wall 1314 and the enclosure wall 1315, enabling the supporting wall 1314 and the enclosure wall 1315 to form a stable integral structure with higher strength. Furthermore, the first reinforcing part 13161 is also provided at the connection between the supporting wall 1314 and the enclosure wall 1315, which can strengthen the connection between the two and ensure the strength and stability of the connection.

[0106] The reinforcing structure 1316 also includes a second reinforcing part 13162, which is disposed between at least two adjacent first reinforcing parts 13161 and extends circumferentially. The second reinforcing part 13162 can reinforce the support wall 1314 in the circumferential direction, so that the force can be distributed at the second reinforcing part 13162, and the support wall 1314 is prevented from deforming under the action of external force, thus affecting the overall stability of the garment processing equipment.

[0107] The reinforcing structure 1316 also includes a third reinforcing part 13163, which extends circumferentially. The third reinforcing part 13163 can reinforce the support wall 1314 in the circumferential direction, so that the force can be distributed at the third reinforcing part 13163, avoiding deformation of the support wall 1314 under the action of external force, which would affect the overall stability of the garment processing equipment. Furthermore, the third reinforcing part 13163 is located near the center of the support wall 1314, which can improve the strength at the center of the support wall 1314, ensure the strength of the connection between the center of the support wall 1314 and the garment processing tube assembly 2, and ensure that the garment processing tube assembly 2 can be stably supported on the support plate 12131.

[0108] Each of the first reinforcing parts 13161 is connected to the third reinforcing part 13163 at one end near the center of the support wall 1314, so as to better realize the transmission and distribution of force.

[0109] Referring to Figures 6-10, a support member 11 is provided on the support wall 1314. The support member 11 is used to support the clothing processing cylinder assembly 2 of the clothing processing equipment. The support member 11 is connected to the clothing processing cylinder assembly 2, that is, the support wall 1314 is used to support the clothing processing cylinder assembly 2 of the clothing processing equipment.

[0110] According to some embodiments of this application, 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. The clothing processing drum can be connected to the support wall 1314 and then placed on the support plate 12131 to support the clothing processing drum assembly 2 with the high-strength support plate 12131, thereby ensuring the stability of the clothing processing drum assembly 2.

[0111] When the projections of the support member 11 and the air vent 1013 on the plane where the support wall 1314 is located overlap, the structure of the support plate 12131 cannot cover the center position of the first opening 1011. When the support plate 12131 needs to support the clothing handling drum assembly, the clothing handling drum cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing handling drum assembly 2, which may lead to the instability of the clothing handling drum assembly 2.

[0112] Furthermore, when the garment handling drum assembly 2 is connected to other structures covering the center of the first opening 1011, in order to improve the strength of the structure connected to the garment handling drum assembly 2, this part of the structure needs to be designed with a reinforcing structure 1316 or use a high-strength metal material to ensure its support stability for the garment handling drum assembly 2, thus increasing the overall production cost of the garment handling equipment. Therefore, the projections of the support member 11 and the air vent 1013 in the plane where the support wall 1314 is located do not overlap.

[0113] The support member 11 includes a bearing housing 111 and a bearing 112. The bearing housing 111 is disposed on the support wall 1314 and is fixedly disposed on the support wall 1314 to provide an installation position for the bearing 112 and to limit the bearing 112, ensuring the stability of the bearing 112. The bearing 112 is disposed on the bearing housing 111 and is used to cooperate with the rotating shaft 23 on the garment processing tube assembly 2 to support the garment processing tube assembly 2. Thus, the garment processing tube assembly 2 can be rotatably connected to the bearing housing 111 through the bearing 112, that is, the garment processing tube assembly 2 is supported on the support wall 1314 and can rotate under the drive of a motor.

[0114] Specifically, the bearing 112 includes an outer bearing and an inner bearing. The inner bearing is rotatably mounted in the inner hole of the outer bearing. The outer bearing is fixedly connected to the bearing housing 111. The inner bearing is fixedly connected to the rotating shaft 23 of the clothing processing tube assembly 2, so that the clothing processing tube assembly 2 can rotate relative to the bearing housing 111 and the support wall 1314 fixedly connected to the bearing housing 111, and can be supported on the support wall 1314.

[0115] As shown in Figure 10, the support wall 1314 has a placement recess 1311 on the side facing away from the first opening 1011. The bearing seat 111 is located in the placement recess 1311. By providing the placement recess 1311 on the support wall 1314, not only can installation space be provided for the bearing seat 111, but the mating area between the support wall 1314 and the bearing seat 111 can also be increased, making the setting of the bearing seat 111 more stable. Furthermore, it can also prevent the setting of the bearing seat 111 from affecting the overall size of the clothing processing equipment in the axial direction of the clothing processing drum assembly 2, thereby realizing the miniaturization and weight reduction of the clothing processing equipment.

[0116] The shape of the bearing seat 111 is adapted to the shape of the placement recess 1311 so that the bearing seat 111 can be completely embedded in the placement recess 1311. The inner wall of the placement recess 1311 limits the bearing seat 111, ensuring the stability of the bearing seat 111. In addition, it can also prevent the placement recess 1311 from occupying too much space and affecting the space used for ventilation inside the first ventilation cavity 102, and reduce the impact of the placement recess 1311 on the wind resistance inside the first ventilation cavity 102.

[0117] Furthermore, the recess 1311 is located on the side of the support wall 1314 facing away from the first opening 1011. This allows the bearing housing 111 to be located outside the ventilation cavity, so that the bearing 112 and the bearing housing 111 do not need to directly contact the airflow in the first ventilation cavity 102. This avoids water vapor in the airflow from corroding the bearing 112 or the bearing housing 111 and affecting the service life of the bearing 112 and the bearing housing 111.

[0118] The bottom wall of the recess 1311 is provided with a through hole 1312 to allow the bearing seat 111 or the shaft 23 to pass through, so as to connect the bearing seat 111 located on the rear side of the support wall 1314 and the clothing handling tube assembly 2 located on the front side of the support wall 1314.

[0119] Referring to Figure 10, the bearing housing 111 includes a first housing body 1111 and a second housing body 1112. The first housing body 1111 and the second housing body 1112 are arranged opposite to each other and define an installation space. The installation space provides space for the installation of the bearing 112. The bearing 112 is a rolling bearing and is located in the installation space. The rolling bearing includes an outer bearing and an inner bearing. The outer bearing is fixedly installed in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23. The first housing body 1111 and the second housing body 1112 stop on opposite sides of the outer ring of the rolling bearing. That is, the first housing body 1111 and the second housing body 1112 limit the bearing 112 on both sides of the bearing 112 axially to ensure the stability of the bearing 112. The rotating shaft 23 is provided with a limiting step 231, which stops on one side of the inner ring of the rolling bearing to prevent the rotating shaft 23 from moving axially 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 handling tube assembly 2 connected to the rotating shaft 23 can rotate relative to the support plate 12131.

[0120] Referring to Figures 1-9, in some embodiments, the garment processing device further includes a volute 132, and a portion of the flow channel upstream of the first ventilation cavity 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 shell assembly connecting the ventilation channel and the inlet of the garment processing cavity 201.

[0121] Specifically, the support plate 12131 is also provided with a second opening 1012, which is arranged at intervals from the first opening 1011. The volute 132 is disposed on the support plate 12131 and defines a second ventilation cavity 103 communicating with the second opening 1012. The air vent 1013 connects the second ventilation cavity 103 and the first ventilation cavity 102. The airflow in the garment processing equipment 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 passes through the second ventilation cavity 103, the air vent 1013, and the first ventilation cavity 102 in sequence to reach the first opening 1011, and then enters the garment processing cavity 201 through the first opening 1011.

[0122] Since the volute 132 and the support plate 12131 are connected after being formed separately, and the volute 132 does not bear the supporting function, the volute 132 can be made of low-strength and low-cost materials, which reduces the production cost of the garment processing equipment.

[0123] In other embodiments, the flow channel upstream of the first ventilation cavity 102 may also be defined by other structures, such as by a mounting base defining the flow channel upstream of the first ventilation cavity 102, which connects the outlet of the clothing processing cavity 201 and the air outlet 1013, and can also realize the circulation of airflow inside the drying room.

[0124] Referring to the embodiments shown in Figures 4-9, the volute 132 covers the second opening 1012 and the air passage 1013 to connect the second opening 1012 and the air passage 1013. The seal between the volute 132 and the corresponding structural contact portion of the first ventilation cavity 102 is achieved by at least a portion of the volute 132 being stacked on the outside of the cavity wall of the first ventilation cavity 102. This stacking arrangement increases the contact area between the volute 132 and the corresponding structural contact portion of the cavity wall of the first ventilation cavity 102, ensuring a good seal between the volute 132 and the support plate 12131.

[0125] In some embodiments, the support plate 12131 can be a metal part, so that the support plate 12131 has higher strength by using a high-strength metal material, thereby having sufficient strength to support the clothing handling tube assembly 2 and to connect with the clothing handling tube assembly 2.

[0126] In some embodiments, the volute 132 can be a plastic part, which reduces the difficulty of production and processing while utilizing the low density and high strength characteristics of plastic materials to make the volute 132 have sufficient strength to ensure the stability of the volute 132 setting, and at the same time makes the volute 132 lighter, realizing the lightweighting of the garment processing equipment.

[0127] As shown in Figures 6-8, a volute tongue 1321 is formed on the volute 132. The projection of the volute tongue 1321 on the plane where the first opening 1011 is located is between the first opening 1011 and the second opening 1012. The shape and size of the volute tongue 1321 can improve the flow characteristics of the airflow, reduce wind resistance, and allow the airflow to flow more smoothly from the second opening 1012 to the first opening 1011, thereby reducing noise and vibration.

[0128] Since the structure of the volute tongue 1321 is relatively complex, by setting the volute tongue 1321 on the volute housing 132, the processing difficulty of the support plate 12131 can be reduced, which is conducive to the integral stamping of the support plate 12131 and ensures that it can more stably support the clothing handling tube assembly 2.

[0129] In some embodiments, the portion of the volute 132 that mates with the cavity wall of the first ventilation cavity 102 is tangent to the first opening 1011 to reduce airflow resistance and ensure ventilation performance within the ventilation cavity.

[0130] According to some embodiments of this application, the garment processing equipment further includes an outer cover (not shown in the figure), which is disposed on one side of the support plate 12131 in the thickness direction and covers the cavity wall of the first ventilation cavity 102 and the volute 132, so as to reduce the noise during the operation of the garment processing equipment and achieve functions such as heat insulation and noise reduction.

[0131] As shown in Figures 1 and 2, the outer side of the cavity wall of the first ventilation cavity 102 has a limiting protrusion 1317. The limiting protrusion 1317 extends along the hole edge of the air outlet 1013 and stops on one side of the volute 132 to facilitate the assembly of the volute 132. At the same time, it increases the sealing area between the volute 132 and the support plate 12131, thereby improving the sealing performance of the ventilation cavity.

[0132] The outer cover is connected to the support plate 12131 by fasteners. The limiting protrusion 1317 is provided with a fastening hole 13171. The outer cover is connected to the fastening hole 13171 by fasteners to set the outer cover on the limiting protrusion 1317. Thus, the high-strength support plate 12131 structure can be used to support the connected outer cover and ensure the stability of the outer cover setting.

[0133] As shown in Figures 5-8, the clothing handling drum assembly 2 includes a drum body 211 and an air inlet hood 22. One axial end of the drum body 211 has a clothing loading / unloading port, and the other axial end has an open opening. The clothing loading / unloading port faces the front of the clothing handling equipment, allowing the user to load clothing into the clothing handling chamber 201. The open opening faces the rear of the clothing handling equipment, allowing airflow to enter the clothing handling chamber 201 for drying. The air inlet hood 22 covers the open opening to define the clothing handling chamber 201 with the drum body 211. The air inlet hood 22 serves two purposes: firstly, it separates the first ventilation chamber 102 from the clothing handling chamber 201, preventing clothing from entering the first ventilation chamber 102 through the open opening; secondly, it provides an installation position for the rotating shaft 23, ensuring stable support for the entire clothing handling drum assembly 2.

[0134] The air inlet hood 22 also has a second extension extending in a direction away from the cylinder 211. The second extension has a non-perforated structure and does not correspond to the first opening 1011. The second extension can separate the clothing handling cylinder assembly 2 from the support plate 12131, thus avoiding interference between the clothing handling cylinder assembly 2 and the support plate 12131 during rotation.

[0135] The second extension is located between the first extension 223 and the cylinder 211, and the first extension 223 extends away from the cylinder 211 relative to the second extension.

[0136] The second ventilation chamber 103 is equipped with a fan wheel that is opposite to the second opening 1012, which is used to drive the airflow to circulate within the first ventilation chamber 102, the second ventilation chamber 103, the air duct and the clothing processing chamber 201.

[0137] According to some embodiments of this application, the garment processing device further includes a mounting base, which defines an air duct to connect the garment processing chamber 201 and the second port 1012. A heating element is provided inside the air duct. During operation of the garment processing device, the humid and cold airflow in the garment processing chamber 201 passes through the air duct defined by the mounting base, where it is heated and dehumidified. It then passes through the second port 1012 and, driven by the impeller, enters the second ventilation chamber 103, the air outlet 1013, and the first ventilation chamber 102. The dry and hot airflow in the first ventilation chamber 102 then enters the garment processing chamber 201 through the first port 1011 and the air inlet 2231 of the garment processing cylinder assembly 2 to dry the garments.

[0138] According to some embodiments of this application, the clothing processing device further includes a heat pump system, which comprises an evaporator, a condenser, and a compressor, and the heating element includes the evaporator and the condenser. Inside the clothing processing chamber 201, hot, dry air passes through the wet clothing; the residual moisture on the clothing absorbs heat, turning the air into humid, hot air. This humid, hot air enters the air duct, and after passing through the condenser, it is transformed into dry, cold air, with water vapor in the air condensing into water droplets and being discharged. At this time, the dry, cold air continues to be heated and pressurized by the compressor and evaporator.

[0139] A specific embodiment of the garment processing device of this application is described below with reference to the illustrations.

[0140] As shown in Figures 1-12, the garment processing equipment includes a mounting base, a heat pump system, an air duct housing assembly, and a garment processing drum assembly 2.

[0141] The air duct housing assembly includes a separately molded support plate 12131 and a volute 132. The support plate 12131 can be made of metal, utilizing high-strength metal materials to give it higher strength, thus providing sufficient strength to support and connect with the garment handling drum assembly 2. The volute 132 can be made of plastic, reducing manufacturing complexity while utilizing the low-density, high-strength properties of plastic to ensure sufficient strength and stability of the volute 132, while also reducing its weight, thus achieving a lightweight garment handling device.

[0142] The support plate 12131 is a one-piece 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 has a first opening 1011 and a second opening 1012, with the second opening 1012 spaced apart from the first opening 1011. The cavity wall of the first ventilation cavity 102 includes a support wall 1314 opposite to the first opening 1011 and a surrounding wall 1315 extending circumferentially along the first opening 1011. The first opening 1011 and the first ventilation cavity 102 are opposite to and communicate with each other in the thickness direction of the support plate 12131. Therefore, the support plate 12131 can be one-piece stamped from sheet metal, simplifying the forming method of the support plate 12131 and reducing the production cost of the support plate 12131. An air vent 1013 is provided on the cavity wall of the first ventilation cavity 102 and communicates with the inside and outside of the first ventilation cavity 102.

[0143] The projection of the air vent 1013 onto the plane of the first opening 1011 is located within the first opening 1011, and the projected area of ​​the air vent 1013 onto the plane of the first opening 1011 is less than half the area of ​​the first opening 1011.

[0144] The projection of the air vent 1013 onto the plane of the first opening 1011 extends along a first direction, and the second direction is radial to the first opening 1011 and 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 each other in the thickness direction of the support plate 12131. Therefore, the line of intersection between the cavity wall of the first ventilation cavity 102 and the plane of the first opening 1011 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 connected to the edge of the first opening 1011. The air passage 1013 includes a portion disposed on the side wall of the first ventilation cavity 102 and a portion disposed on the rear wall of the first ventilation cavity 102. The portion of the air passage 1013 disposed on the side wall of the first ventilation cavity 102 mainly affects the size of the air passage 1013 in the first direction, and the portion of the air passage 1013 disposed on the rear wall of the first ventilation cavity 102 mainly affects the size of the air passage 1013 in the second direction.

[0145] Among them, the size X of the projection of the air vent 1013 in the first direction is 0.2-0.8 times the diameter of the first opening 1011, and the size Y of the projection of the air vent 1013 in the second direction is 0.1-0.4 times the diameter of the first opening 1011.

[0146] An air vent 1013 is disposed on the cavity wall of the first ventilation cavity 102 and near the edge of the first opening 1011. The air vent 1013 has a first edge 1313 and a second edge 122 that are radially opposite to each other in the first opening 1011. The second edge 122 is a part of the edge of the first opening 1011, and the first edge 1313 is the edge of the air vent 1013 defined by the corresponding structure of the cavity wall of the first ventilation cavity 102. The first edge 1313 and the second edge 122 together define the air vent 1013.

[0147] Wherein, the radial distance between the projection of the first edge 1313 onto 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 onto 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.

[0148] Alternatively, the projection of the first edge 1313 onto the plane where the first opening 1011 is located forms an arc that curves toward the center of the first opening 1011. This ensures the connection area between the corresponding structure of the first ventilation cavity 102 wall and the support plate body, the strength of the corresponding structure of the rear wall of the first ventilation cavity 102, and the ventilation area of ​​the air outlet 1013, while reducing the material required for the production of the support plate 12131 and lowering production costs.

[0149] Furthermore, the projection of the first edge 1313 onto the plane where the first opening 1011 is located forms an arc that curves toward the center of the first opening 1011. The stability of the arch shape can also be utilized to ensure the strength of the structure corresponding to the rear wall of the first ventilation cavity 102.

[0150] The upstream portion of the flow channel 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 passage 1013 to connect the second opening 1012 and the air passage 1013. The volute 132 is disposed on the support plate 12131 and defines a second ventilation cavity 103 connected to the second opening 1012. The air passage 1013 connects the second ventilation cavity 103 and the first ventilation cavity 102. The airflow in the garment processing equipment 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 passes through the second ventilation cavity 103, the air passage 1013 and the first ventilation cavity 102 in sequence to reach the first opening 1011, and then enters the garment processing cavity 201 through the first opening 1011.

[0151] The seal between the volute 132 and the corresponding structural contact portion of the cavity wall of the first ventilation cavity 102 is achieved by at least a portion of the volute 132 being stacked on the outside of the cavity wall of the first ventilation cavity 102 to achieve a sealing fit. By stacking, the contact area between the volute 132 and the corresponding structural contact portion 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.

[0152] A volute 1321 is formed on the volute 132. The projection of the volute 1321 on the plane where the first opening 1011 is located is between the first opening 1011 and the second opening 1012. The shape and size of the volute 1321 can improve the flow characteristics of the airflow, reduce wind resistance, and allow the airflow to flow more smoothly from the second opening 1012 to the first opening 1011, thereby reducing noise and vibration.

[0153] Since the structure of the volute tongue 1321 is relatively complex, by setting the volute tongue 1321 on the volute housing 132, the processing difficulty of the support plate 12131 can be reduced, which is conducive to the integral stamping of the support plate 12131 and ensures that it can more stably support the clothing handling tube assembly 2.

[0154] In some embodiments, the portion of the volute 132 that mates with the cavity wall of the first ventilation cavity 102 is tangent to the first opening 1011 to reduce airflow resistance and ensure ventilation performance within the ventilation cavity.

[0155] The support wall 1314 and the enclosure wall 1315 together define the first ventilation cavity 102. The enclosure wall 1315 gradually extends outward from the support wall 1314 to the first opening 1011. 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 enclosure wall 1315 and the support wall 1314, which have a supporting function, can be further improved. When the support wall 1314 needs to bear the function of supporting the clothing handling tube assembly 2, the support wall 1314 has sufficient strength to ensure the stability of the clothing handling tube assembly 2.

[0156] The reinforcing structure 1316 includes a plurality of first reinforcing parts 13161, which are arranged circumferentially at intervals on a circumference, and each first reinforcing part 13161 extends radially on the circumference. The center of the circumference is the center of the support wall 1314. When the support wall 1314 needs to bear the function of supporting the clothing handling tube assembly 2, the center position of the support wall 1314 is connected to the clothing handling tube assembly 2 to support the clothing handling tube assembly 2.

[0157] Therefore, when the center of the support wall 1314 needs to support the clothing handling tube assembly 2, the multiple first reinforcing parts 13161 surrounding the center of the support wall 1314 can strengthen the strength of the center of the support wall 1314 in the radial direction, so that the force can be transmitted radially to the support plate body with higher strength, ensuring the strength of the center of the support wall 1314 and the stability of the structure, and ensuring the stability of the clothing handling tube assembly 2.

[0158] A portion of the first reinforcing part 13161 is located in the supporting wall 1314 and another portion extends to the enclosure wall 1315. Thus, the first reinforcing part 13161 can simultaneously reinforce the supporting wall 1314 and the enclosure wall 1315, making the overall strength of the supporting wall 1314 and the enclosure wall 1315 higher and the structure more stable.

[0159] The first reinforcing part 13161 connects the supporting wall 1314 and the enclosure wall 1315, enabling the supporting wall 1314 and the enclosure wall 1315 to form a stable integral structure with higher strength. Furthermore, the first reinforcing part 13161 is also provided at the connection between the supporting wall 1314 and the enclosure wall 1315, which can strengthen the connection between the two and ensure the strength and stability of the connection.

[0160] The reinforcing structure 1316 also includes a second reinforcing part 13162, which is disposed between at least two adjacent first reinforcing parts 13161 and extends circumferentially. The second reinforcing part 13162 can reinforce the support wall 1314 in the circumferential direction, so that the force can be distributed at the second reinforcing part 13162, avoiding deformation of the support wall 1314 under the action of external force, which would affect the overall stability of the air duct shell assembly.

[0161] The reinforcing structure 1316 also includes a third reinforcing part 13163, which extends circumferentially. The third reinforcing part 13163 can reinforce the support wall 1314 in the circumferential direction, so that the force can be distributed at the third reinforcing part 13163, avoiding deformation of the support wall 1314 under the action of external force, which would affect the overall stability of the air duct shell assembly. Furthermore, the third reinforcing part 13163 is located near the center of the support wall 1314, which can improve the strength at the center of the support wall 1314, ensure the strength of the connection between the center of the support wall 1314 and the clothing handling tube assembly 2, and ensure that the clothing handling tube assembly 2 can be stably supported on the support plate 12131.

[0162] Each of the first reinforcing parts 13161 is connected to the third reinforcing part 13163 at one end near the center of the support wall 1314, so as to better realize the transmission and distribution of force.

[0163] The air duct housing assembly also includes an outer cover, which is located on one side of the support plate 12131 in the thickness direction and covers the cavity wall of the first ventilation cavity 102 and the volute 132, so as to reduce the noise during the operation of the clothing processing equipment and achieve functions such as heat insulation and noise reduction.

[0164] As shown in Figures 1 and 2, the outer side of the cavity wall of the first ventilation cavity 102 has a limiting protrusion 1317. The limiting protrusion 1317 extends along the hole edge of the air outlet 1013 and stops on one side of the volute 132 to facilitate the assembly of the volute 132. At the same time, it increases the sealing area between the volute 132 and the support plate 12131, thereby improving the sealing performance of the ventilation cavity.

[0165] The outer cover is connected to the support plate 12131 by fasteners. The limiting protrusion 1317 is provided with a fastening hole 13171. The outer cover is connected to the fastening hole 13171 by fasteners to set the outer cover on the limiting protrusion 1317. Thus, the high-strength support plate 12131 structure can be used to support the connected outer cover and ensure the stability of the outer cover setting.

[0166] A support member 11 is provided on the support wall 1314, and the support member 11 is used to support the clothing processing cylinder assembly 2 of the clothing processing equipment. The support member 11 is connected to the clothing processing cylinder assembly 2, that is, the support wall 1314 is used to support the clothing processing cylinder assembly 2 of the clothing processing equipment.

[0167] According to some embodiments of this application, 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. The clothing processing drum can be connected to the support wall 1314 and then placed on the support plate 12131 to support the clothing processing drum assembly 2 with the high-strength support plate 12131, thereby ensuring the stability of the clothing processing drum assembly 2.

[0168] When the projections of the support member 11 and the air vent 1013 on the plane where the support wall 1314 is located overlap, the structure of the support plate 12131 cannot cover the center position of the first opening 1011. When the air duct shell assembly needs to support the clothing handling drum assembly, the clothing handling drum cannot be directly connected to the support plate 12131, and the high-strength support plate 12131 cannot be used to support the clothing handling drum assembly 2, which may lead to the unstable setting of the clothing handling drum assembly 2.

[0169] Furthermore, when the garment handling drum assembly 2 is connected to other structures covering the center of the first opening 1011, in order to improve the strength of the structure connected to the garment handling drum assembly 2, this part of the structure needs to be designed with a reinforcing structure 1316 or use a high-strength metal material to ensure its support stability for the garment handling drum assembly 2, thus increasing the overall production cost of the air duct shell assembly. Therefore, the projections of the support member 11 and the air vent 1013 in the plane where the support wall 1314 is located do not overlap.

[0170] The support member 11 includes a bearing housing 111 and a bearing 112. The bearing housing 111 is disposed on the support wall 1314 and is fixedly disposed on the support wall 1314 to provide an installation position for the bearing 112 and to limit the bearing 112, ensuring the stability of the bearing 112. The bearing 112 is disposed on the bearing housing 111 and is used to cooperate with the rotating shaft 23 on the garment processing tube assembly 2 to support the garment processing tube assembly 2. Thus, the garment processing tube assembly 2 can be rotatably connected to the bearing housing 111 through the bearing 112, that is, the garment processing tube assembly 2 is supported on the support wall 1314 and can rotate under the drive of a motor.

[0171] Specifically, the bearing 112 includes an outer bearing and an inner bearing. The inner bearing is rotatably mounted in the inner hole of the outer bearing. The outer bearing is fixedly connected to the bearing housing 111. The inner bearing is fixedly connected to the rotating shaft 23 of the clothing processing tube assembly 2, so that the clothing processing tube assembly 2 can rotate relative to the bearing housing 111 and the support wall 1314 fixedly connected to the bearing housing 111, and can be supported on the support wall 1314.

[0172] As shown in Figure 10, the support wall 1314 has a placement recess 1311 on the side facing away from the first opening 1011. The bearing seat 111 is located in the placement recess 1311. By providing the placement recess 1311 on the support wall 1314, not only can installation space be provided for the bearing seat 111, but the mating area between the support wall 1314 and the bearing seat 111 can also be increased, making the setting of the bearing seat 111 more stable. Furthermore, it can also prevent the setting of the bearing seat 111 from affecting the overall size of the clothing processing equipment in the axial direction of the clothing processing drum assembly 2, thereby realizing the miniaturization and weight reduction of the clothing processing equipment.

[0173] The shape of the bearing seat 111 is adapted to the shape of the placement recess 1311 so that the bearing seat 111 can be completely embedded in the placement recess 1311. The inner wall of the placement recess 1311 limits the bearing seat 111, ensuring the stability of the bearing seat 111. In addition, it can also prevent the placement recess 1311 from occupying too much space and affecting the space used for ventilation inside the first ventilation cavity 102, and reduce the impact of the placement recess 1311 on the wind resistance inside the first ventilation cavity 102.

[0174] Furthermore, the recess 1311 is located on the side of the support wall 1314 facing away from the first opening 1011. This allows the bearing housing 111 to be located outside the ventilation cavity, so that the bearing 112 and the bearing housing 111 do not need to directly contact the airflow in the first ventilation cavity 102. This avoids water vapor in the airflow from corroding the bearing 112 or the bearing housing 111 and affecting the service life of the bearing 112 and the bearing housing 111.

[0175] The bottom wall of the recess 1311 is provided with a through hole 1312 to allow the bearing seat 111 or the shaft 23 to pass through, so as to connect the bearing seat 111 located on the rear side of the support wall 1314 and the clothing handling tube assembly 2 located on the front side of the support wall 1314.

[0176] Referring to Figure 10, the bearing housing 111 includes a first housing body 1111 and a second housing body 1112. The first housing body 1111 and the second housing body 1112 are arranged opposite to each other and define an installation space. The installation space provides space for the installation of the bearing 112. The bearing 112 is a rolling bearing and is located in the installation space. The rolling bearing includes an outer bearing and an inner bearing. The outer bearing is fixedly installed in the installation space, and the inner bearing is fixedly connected to the rotating shaft 23. The first housing body 1111 and the second housing body 1112 stop on opposite sides of the outer ring of the rolling bearing. That is, the first housing body 1111 and the second housing body 1112 limit the bearing 112 on both sides of the bearing 112 axially to ensure the stability of the bearing 112. The rotating shaft 23 is provided with a limiting step 231, which stops on one side of the inner ring of the rolling bearing to prevent the rotating shaft 23 from moving axially 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 handling tube assembly 2 connected to the rotating shaft 23 can rotate relative to the air duct shell assembly.

[0177] The garment processing cylinder assembly 2 defines a garment processing cavity 201 for accommodating garments to be processed. A portion of the garment processing cylinder assembly 2 extends from the first opening 1011 into the first ventilation cavity 102. Thus, without changing the external dimensions of the garment processing equipment, the garment processing cylinder assembly 2 can be designed to be deeper, thereby increasing the capacity of the garment processing cavity 201. The garment processing equipment can process more and larger garments at the same time, improving the user experience.

[0178] The garment processing drum assembly 2 has an air inlet 2231, which can be directly connected to the first ventilation chamber 102 and the garment processing chamber 201. During the airflow process, the airflow in the first ventilation chamber 102 can directly enter the garment processing chamber 201 through the air inlet 2231. This reduces airflow resistance and lowers the production cost of the garment processing equipment.

[0179] The garment handling drum assembly 2 is rotatably supported on the air duct housing assembly via a pivot 23. The garment handling drum assembly 2 includes a drum body 211 and an air inlet hood 22. One axial end of the drum body 211 has a garment loading / unloading port, and the other axial end has an open opening. The garment loading / unloading port faces the front of the garment handling equipment, allowing the user to load garments into the garment handling chamber 201. The open opening faces the rear of the garment handling equipment, allowing airflow to enter the chamber defined by the drum body 211 for drying the garments. The chamber defined by the drum body 211 is the main part of the garment handling chamber 201 used to hold the garments. The air inlet hood 22 covers the open opening to jointly define the garment handling chamber 201 with the drum body 211. The air inlet hood 22 serves two purposes: firstly, it separates the first ventilation chamber 102 from the garment handling chamber 201, preventing garments from entering the first ventilation chamber 102 through the open opening; secondly, it provides an installation position for the pivot hood 23, which is located within the air inlet hood 22.

[0180] The air inlet 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 2231 from affecting the connection between the rotating shaft 23 and the air inlet cover 22, and at the same time to avoid the setting of the rotating shaft 23 from affecting the air inlet area of ​​the air inlet 2231, so as to ensure the air intake volume of the air inlet 2231.

[0181] The middle part of the air inlet hood 22 extends toward the direction of the clothing loading and unloading port to form a receiving recess 221 on the outer surface of the air inlet hood 22. The rotating shaft 23 is provided on the bottom wall of the receiving recess 221 and protrudes from the plane where the opening of the receiving recess 221 is located. The opening of the receiving recess 221 provides installation space for the rotating shaft 23 and the connection structure between the rotating shaft 23 and the air inlet hood 22, avoiding interference with the rear structure and affecting the normal operation and rotation of the clothing handling tube assembly 2.

[0182] The rotating shaft 23 protrudes from the plane where the opening of the receiving recess 221 is located, so as to be rotatably connected to the structure located behind the clothing handling tube assembly 2, so that the entire clothing handling tube assembly 2 can be supported and mounted on the air duct shell assembly.

[0183] The air inlet hood 22 has a second extension and a first extension 223 extending in a direction away from the cylinder 211. The first extension 223 extends into the first ventilation cavity 102. The second extension has a non-perforated structure. The second extension is located between the first extension 223 and the cylinder 211.

[0184] In some embodiments, the second ventilation cavity 103 of the air duct housing assembly is provided with a fan wheel disposed opposite to the second opening 1012, and the garment handling device further includes a mounting base, which defines an air duct to communicate with the garment handling cavity 201 and the second opening 1012.

[0185] A heating element is installed inside the air duct. During the operation of the clothing processing equipment, the humid and cold airflow in the clothing processing chamber 201 is heated and dehumidified in the air duct defined by the mounting base, passes through the second port 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 impeller. The dry and hot airflow in the first ventilation chamber 102 then enters the clothing processing chamber 201 through the air inlet 2231 of the clothing processing cylinder assembly 2 to dry the clothes.

[0186] The garment processing equipment also includes a heat pump system, which comprises an evaporator, a condenser, and a compressor. The heating elements include the evaporator and condenser. Inside the garment processing chamber 201, hot, dry air passes through the wet clothes. The residual moisture on the clothes absorbs heat, turning the air into humid, hot air. This humid, hot air enters the air duct and, after passing through the condenser, is transformed into dry, cold air. Water vapor in the air condenses into water droplets and is discharged. Meanwhile, the dry, cold air continues to be heated and pressurized by the compressor and evaporator.

[0187] 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, it also surrounds the outside of the air inlet 2231, so as to achieve a seal between the air duct shell assembly and the clothing treatment tube assembly 2. The sealing ring 3 is fixed on the air duct shell assembly, and the air inlet cover 22 is provided with an annular stop protrusion 225 that is movable and cooperates with the sealing ring 3.

[0188] Referring to Figures 7-9, the support plate 12131 includes a limiting flange 121. The edge of the first opening 1011 has a limiting flange 121 extending toward the 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, providing an installation position for the sealing ring 3 and preventing the sealing ring 3 from moving and affecting the sealing performance.

[0189] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
