TECHNICAL FIELD
[0001] The utility model relates to the technical field of household appliances, and mainly relates to a clothes treatment equipment. BACKGROUND
[0002] With the development of society and technology, clothes treatment devices have become common household appliances. With the rapid development of living standards, people use clothes treatment devices more and more frequently, and the requirements are increasingly improved.
[0003] At present, during the drying operation of the clothes treatment device, lint will be generated due to the drying and fluffing of the clothes, especially cotton and wool. These lint will enter the air duct with the air in the drum. If not cleaned in time, the lint will adhere to important components such as the evaporator and the condenser, affecting the heat exchange effect of the air and the two components, and thus adversely affecting the drying effect.
[0004] In the prior art, a filter grid structure is added to the return air inlet to block the lint, but this will greatly affect the air volume and drying efficiency of the whole machine. UTILITY MODEL CONTENTS
[0005] The utility model aims to provide a clothes treatment equipment to solve the problem that the filter structure in the prior art is arranged at the return air inlet, affecting the circulating air efficiency.
[0006] To solve the above technical problems, the utility model adopts the following technical scheme:
[0007] One aspect of the present application is a clothes treatment equipment, comprising a box body forming an outer shell of the clothes treatment equipment; a drum assembly arranged in the box body, the drum assembly forming a clothes treatment cavity inside; an air inlet and a return air inlet communicating with the clothes treatment cavity are respectively arranged on the outer wall of the drum assembly; a mounting seat is arranged above the drum assembly in the box body, and an evaporator cavity is arranged in the mounting seat; an evaporator and a condenser are installed in the evaporator cavity; an air inlet and an air outlet are respectively arranged on the mounting seat, and the air inlet and the air outlet respectively communicate with the evaporator cavity; the air outlet is used for communication with the air inlet; the opening of the air inlet faces downward, and the air inlet is used for communication with the return air inlet; a return air pipe is connected between the return air inlet and the air inlet, the lower end of the return air pipe is connected with the return air inlet, and the upper end of the return air pipe is connected with the air inlet; a gland is arranged inside the air inlet, and the gland is used for clamping the upper end of the return air pipe between the gland and the side wall of the air inlet; wherein the height direction of the clothes treatment equipment is the first direction, and the top surface of the gland is inclined from high to low in the first direction.
[0008] The above technical solution has the following advantages or beneficial effects: by connecting the upper end of the return air pipe with the air inlet of the mounting seat, and connecting the lower end of the return air pipe with the air inlet of the mounting seat, when the clothes treatment device needs to perform drying work, the airflow in the clothes treatment cavity needs to pass through the return air inlet and the air inlet, and then enter the two-device cavity. In this process, the airflow needs to be transported from bottom to top into the mounting seat located above, and then diffused from the peripheral side of the air inlet into the two-device cavity. Due to the change of the airflow direction, the lint carried in the airflow will be retained on the top of the gland due to the inertial effect. By tilting the top surface of the gland, i.e. the surface extending along the peripheral side of the air inlet, towards the side close to the center of the air inlet in the first direction from high to low, the lint retained on the peripheral side of the top of the gland can receive the gravity component, and under the guiding action of the inclined surface, the lint slides along the inclined direction to the return air pipe. Moreover, during the diffusion of the airflow in the peripheral direction to the two-device cavity, the lint is blocked by the inclined surface, and is more likely to be retained on the top of the gland, and then slides on the side of the inclined surface towards the center of the air inlet, so that most of the lint no longer enters the two-device cavity with the airflow, but is effectively guided back to the return air pipe, thereby greatly reducing the accumulation of lint in the two-device cavity, preventing the attachment of a large amount of lint carried by the airflow in the clothes treatment cavity to important components such as the evaporator and the condenser, affecting the heat exchange efficiency and the working stability. On the other hand, the setting of the gland can also greatly reduce the obstruction to the airflow, thereby improving the air volume and drying efficiency of the whole machine.
[0009] In some embodiments of the present application, a clothes treatment device is provided, wherein the upper end of the return air pipe is provided with an upper flange, the upper flange is located above the peripheral edge of the air inlet; the peripheral edge of the air inlet forms a limiting rib; the gland is located above the limiting rib, and the upper flange is clamped between the gland and the limiting rib.
[0010] Another technical solution in the above technical solution has the following advantages or beneficial effects: by setting the upper flange of the upper end of the return air pipe on the upper flange of the upper end of the return air pipe, and cooperating with the limiting rib formed by the peripheral edge of the air inlet. The gland is arranged above the limiting rib, so that the upper flange can be tightly clamped between the gland and the limiting rib, thereby improving the stable connection between the return air pipe and the air inlet. Moreover, due to the close cooperation between the upper flange, the limiting rib and the gland, the return air pipe is not easy to loosen due to vibration or airflow impact during long-term use, which is beneficial to maintaining smooth airflow.
[0011] In some embodiments of the present application, a laundry treating apparatus is provided, the grommet includes an upper pressing wall and an inner flange, the upper pressing wall is arranged above the circumferential edge of the air inlet, the upper end of the inner flange is connected to the upper pressing wall by bending, and the lower end of the inner flange is nested inside the air return duct and extends downward along the inside of the air return duct, the top surface of the upper pressing wall is configured as the top surface of the grommet, and the top surface of the upper pressing wall is formed with an inclined surface, the inner side of the inclined surface is connected to the upper end of the inner flange by bending.
[0012] Another technical solution in the above technical solution has the following advantages or beneficial effects: Specifically, the entire inner flange extends downward along the inside of the air return duct. The upper end of the inner flange is connected to the upper pressing wall by bending, and the connection between the two forms a continuous transition surface. By arranging the lower end of the inner flange to extend downward and be nested inside the air return duct, the lint at the lower end of the inclined surface is further guided to fall back into the air return duct along the inner flange, so that the lint in the air flow can be more effectively collected and guided into the air return duct, which helps to reduce the accumulation of lint on the upper end of the grommet, thereby preventing the lint accumulated on the upper end of the grommet from being brought into the drum cavity again during air circulation.
[0013] In some embodiments of the present application, a laundry treating apparatus is provided, the grommet includes an upper pressing wall and an inner flange, the upper pressing wall is arranged above the circumferential edge of the air inlet, the upper end of the inner flange is connected to the upper pressing wall by bending, and the lower end of the inner flange is nested inside the air return duct and extends downward along the inside of the air return duct, the top surface of the upper pressing wall is configured as the top surface of the grommet, and the top surface of the upper pressing wall is formed with an inclined surface, the inner side of the inclined surface is connected to the upper end of the inner flange by bending.
[0014] Another technical solution in the above technical solution has the following advantages or beneficial effects: By setting the included angle A to be less than 30°, the lint can be effectively separated and returned to the air return duct under the action of gravity, while the resistance of the air flow is reduced, thereby improving the air volume and drying efficiency. When the included angle A is greater than 30°, the air flow will encounter greater resistance when passing through the inclined surface, thereby increasing energy loss and easily leading to a decrease in air volume and affecting drying efficiency.
[0015] In some embodiments of the present application, a laundry treating apparatus is provided, the grommet includes an upper pressing wall and an inner flange, the upper pressing wall is arranged above the circumferential edge of the air inlet, the upper end of the inner flange is connected to the upper pressing wall by bending, and the lower end of the inner flange is nested inside the air return duct and extends downward along the inside of the air return duct, the top surface of the upper pressing wall is configured as the top surface of the grommet, and the top surface of the upper pressing wall is formed with an inclined surface, the inner side of the inclined surface is connected to the upper end of the inner flange by bending.
[0016] Another technical solution in the above technical solution has the following advantages or beneficial effects: By setting the bent connection between the inclined surface and the upper end of the inner flange as a circular arc transition, the lint falling back into the air return duct along the inner flange from the lower end of the inclined surface can be effectively guided, and at the same time, the vortex and resistance generated by the air flow at the connection between the inclined surface and the inner flange can be reduced, which helps to maintain the smoothness of the air flow at the communication between the mounting seat and the drum assembly.
[0017] In some embodiments of the present application, a laundry treating apparatus is provided, the inner flange is annular, and the inner surface of the inner flange is obliquely arranged towards one side of the center of the air inlet along the first direction from high to low.
[0018] Another technical solution in the above technical solution has the following advantages or beneficial effects: by obliquely arranging the inner surface of the inner flange, the inclined inner surface can not only effectively guide the lint carried in the airflow, but also further slide the lint on one side of the upper pressing wall along the inner flange to the bottom of the return air duct, avoiding the accumulation of lint on one side of the upper pressing wall, and thus preventing the problem of lint adhering to the surfaces of the evaporator and the condenser in the two cavity chambers along the airflow.
[0019] In some embodiments of the present application, a laundry treating apparatus is provided, a straight line extending downward along the inner surface of the inner flange through any point on the inner surface is taken as a reference line, a plane perpendicular to the installation surface of the laundry treating apparatus is taken as a second reference surface, and the included angle B between the reference line and the second reference surface is less than 30°.
[0020] Another technical solution in the above technical solution has the following advantages or beneficial effects: by arranging the inner surface of the inner flange to be inclined more towards one side of the vertical plane within the range of the included angle B between the inner surface and the vertical plane being less than 30°, the lint carried in the airflow can more easily deposit on the inner flange and more smoothly slide into the return air duct in the direction of being inclined towards the center of the return air duct during the process of the airflow flowing from bottom to top. The inner flange can work together with the upper pressing wall to more effectively collect and guide the lint in the airflow into the return air duct, and also avoid forming a large wind resistance to the airflow, thereby maintaining the efficiency of airflow circulation. When the included angle B is greater than 30°, and as the included angle B increases, the airflow will encounter greater resistance when passing through the inner flange, which can easily cause turbulence or vortex in the airflow when passing through the inner flange, resulting in noise and possibly reducing the air volume and affecting the drying efficiency.
[0021] In some embodiments of the present application, a laundry treating apparatus is provided, the upper pressing wall is provided with a first connecting hole, the upper flange is provided with a second connecting hole, the first connecting hole and the second connecting hole are correspondingly arranged, the upper end of the limiting rib is provided with a third connecting hole with an upward opening, the limiting rib is protrusively arranged on the mounting seat, the upper end of the limiting rib is arranged in the second connecting hole, and the opening of the third connecting hole is correspondingly arranged with the first connecting hole, and further comprising a connecting piece, a portion of the connecting piece penetrating through the first connecting hole extends into the third connecting hole to fix the pressing cover and the upper flange on the mounting seat.
[0022] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: the upward protruding part of the limiting rib is arranged in the second connecting hole, so that the upper turning edge can be limited on the limiting rib, the third connecting hole is arranged corresponding to the first connecting hole, so that the connecting piece can be inserted into the limiting rib after passing through the first connecting hole, and then the upper turning edge clamped between the circumferential edge of the air inlet and the upper pressing wall of the cover is tightly fixed on the fixing seat. In this way, not only can the return air duct be reliably fixed on the circumferential side of the air inlet, but also the problem of insufficient sealing performance caused by directly arranging the opening on the mounting seat and affecting the air circulation efficiency can be avoided.
[0023] In some embodiments of the present application, a laundry treating apparatus is provided, and the top of the drum assembly is provided with the return air port, which is arranged below the air inlet.
[0024] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: by arranging the return air port below the air inlet, the airflow can flow from the return air port to the air inlet in a downward direction, and under the action of gravity, the lint trapped on the inclined surface of the cover can fall back into the return air duct more quickly, and then fall back into the drum assembly through the return air duct.
[0025] In some embodiments of the present application, a laundry treating apparatus is provided, and the mounting seat is provided with a filter part, which is arranged on the circumferential side of the air inlet and at the communication between the air inlet and the two vessel cavities; the filter part is arranged higher than the inclined surface.
[0026] Another technical scheme in the above technical scheme has the following advantages or beneficial effects: by arranging the filter part on the circumferential side of the air inlet and at the communication between the air inlet and the two vessel cavities, it can be ensured that the airflow must pass through the filter part before entering the two vessel cavities, and when the lint accumulates, it can fall onto the upper pressing wall below under the action of gravity, and then flow along the inclined surface of the upper pressing wall towards the return air duct, and finally fall back into the drum assembly, and then be discharged to the outside of the laundry treating apparatus through the drain valve assembly.

[0054] It needs to be explained that, Figure 2 It is the internal view of Figure 1 hidden box structure.
[0055] As Figure 1 and Figure 2As shown, in some embodiments, the cabinet 1 can be an overall structure outside the washing machine, and the cabinet 1 is a hollow structure in which other component structures of the washing machine can be arranged, such as a circuit structure (not shown in the figure), an air duct structure, a driving mechanism, and a drain valve assembly 12.
[0056] In some embodiments, the cabinet 1 can be arranged in a hollow cuboid shape or a hollow cylindrical shape, and of course, is not limited to the above shapes. The front side of the cabinet 1 can be provided with a loading port for loading clothes.
[0057] In some embodiments, the cabinet 1 can form an outer shell of the clothes processing device, and the internal space of the cabinet 1 can provide mounting space for components such as the drum assembly 2, the base 13, and the heat pump system. It should be noted that the clothes processing device can be a clothes dryer or a washer-dryer or other clothes processing device.
[0058] In some embodiments, the front surface of the cabinet 1 can be provided with a clothes loading port (not shown in the figure) which communicates with the internal space of the cabinet 1. The front side of the cabinet 1 can be provided with a cabinet door 11 which is used to open and close the clothes loading port on the front side of the cabinet 1, thereby opening and closing the space inside.
[0059] As shown in Figure 1 In some embodiments, the cabinet door 11 and the cabinet 1 can be connected by a hinge, and the cabinet door 11 can rotate around the axis of the hinge, thereby realizing the opening and closing of the cabinet door 11 and opening and closing the clothes loading port.
[0060] As shown in Figure 1 and Figure 2 In some embodiments, the drum assembly 2 can be arranged in the cabinet 1. The front end face of the drum assembly is formed with a drum port 201 which is opposite to the clothes loading port and the cabinet door 11 of the cabinet 1. The drum assembly is formed with a clothes processing cavity 202. The drum port 201 can communicate with the clothes processing cavity 202. The clothes processing cavity 202 can serve as a storage position for work procedures such as clothes washing and drying. After the cabinet door 11 is opened, clothes can be sequentially put into the clothes processing cavity 202 in the drum assembly through the clothes loading port on the front side of the cabinet 1 and the drum port 201 of the drum assembly, and drying is performed.
[0061] As shown in Figure 2 In some embodiments, the drum assembly 2 can be rotatably arranged in the cabinet 1. During the drying process of the clothes in the clothes processing cavity 202, the drum assembly 2 can drive the clothes in the clothes processing cavity 202 to rotate, thereby improving the uniformity and efficiency of the drying of the clothes.
[0062] As shown in Figure 3As shown, in some embodiments, the outer wall of the tube assembly 2 may be provided with an air inlet 203 and an air return outlet 204 that communicate with the clothing processing chamber 202. Airflow can enter the clothing processing chamber 202 through the air inlet 203 and leave the clothing processing chamber 202 through the air return outlet 204.
[0063] like Figure 2 and Figure 3 As shown, in some embodiments, the garment processing apparatus may include a heat pump system. The heat pump system may be located inside the housing. The heat pump system may be used to exchange heat with the airflow within the garment processing chamber 202 to provide dry, hot air to the garment processing chamber 202.
[0064] In some embodiments, the heat pump system may include a compressor 34. The compressor 34 is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor 34 can deliver the high-temperature, high-pressure refrigerant to the condenser.
[0065] In some embodiments, the heat pump system may include a condenser 32. The condenser 32 can be used to receive refrigerant flowing from the compressor 34, and can cool the high-temperature, high-pressure refrigerant gas from the compressor 34 and convert it into a liquid state. The condenser 32 can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.
[0066] In some embodiments, the heat pump system may include a throttling device (not shown). The condenser 32 may deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.
[0067] In some embodiments, the heat pump system may include an evaporator 33. A throttling device may deliver throttled and depressurized refrigerant into the evaporator 33. The evaporator 33 may be used for refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.
[0068] like Figure 2 and Figure 3 As shown, the garment processing equipment may include a mounting base 31. The mounting base 31 may be disposed inside the housing 1 and located above the drum assembly 2. The mounting base 31 may have two chambers 301, in which an evaporator 33 and a condenser 32 may be installed. The two chambers 301 inside the mounting base 31 provide installation space for the evaporator 33 and the condenser 32, which can provide hot airflow for drying clothes by utilizing the thermal circulation process of the refrigerant.
[0069] Figure 4 for Figure 1 A cross-sectional schematic diagram.
[0070] likeFigure 3 and Figure 4 As shown, in some embodiments, the mounting base 31 may be provided with an air inlet 302 and an air outlet 303. The air inlet 302 and the air outlet 303 may be connected to the two chambers 301 respectively. The air outlet 303 may be used to connect with the air inlet 203. The opening of the air inlet 302 faces downward, and the air inlet 302 may be used to connect with the return air inlet 204.
[0071] Specifically, the air inlet 302 is connected to the return air inlet 204, and the air outlet 303 is connected to the air inlet 203. A fan can also be installed between the mounting base 31 and the clothes processing chamber 202. When the fan is started, the air in the clothes processing chamber 202 can flow into the two chambers 301 through the return air inlet 204 and the air inlet 302. When the air flows through the evaporator, the refrigerant at the evaporator absorbs heat, causing the water vapor in the airflow to condense into liquid water, thus greatly reducing the water vapor content in the airflow and obtaining dry and cold air. Then the dry and cold air flows through the condenser. Because the refrigerant at the condenser releases heat, the temperature of the dry and cold air rises, and the airflow after passing through the condenser is dry and hot air. Immediately afterwards, the dry and hot air flows back into the clothes processing chamber 202 through the air outlet 303 and the air inlet 203. At this time, the airflow entering the clothes processing chamber 202 can dry the clothes.
[0072] like Figure 3 As shown, in some embodiments, the garment processing device may include a return air duct 35. The return air duct 35 may be connected between the return air inlet 204 and the air inlet 302. The lower end of the return air duct 35 may be connected to the return air inlet 204, and the upper end of the return air duct 35 may be connected to the air inlet 302. The return air duct 35 serves as a channel connecting the return air inlet 204 and the air inlet 302, ensuring that air inside the cylinder assembly 2 can flow smoothly back to the two chambers 301 for heat exchange. Figure 5 for Figure 4 A magnified view of part A; Figure 6 for Figure 5 A magnified view of section B.
[0073] like Figure 5 and Figure 6 As shown, in some embodiments, the garment handling device may include a pressure cap 36. The pressure cap 36 may be disposed inside the air inlet 302. The pressure cap 36 may be used to clamp the upper end of the return air duct 35 between the bottom of the pressure cap 36 and the side wall of the air inlet 302. Specifically, taking the height direction of the garment handling device as a first direction, the top surface of the pressure cap is inclined from high to low in the first direction, from the periphery away from the center of the air inlet towards the side closer to the center of the air inlet 302.
[0074] It should be noted that the top surface of the gland is inclined towards the side close to the center of the air inlet 302 in the height direction of the clothes treatment apparatus from bottom to top. When the installation surface of the clothes treatment apparatus is a horizontal plane, the height direction of the clothes treatment apparatus is perpendicular to the horizontal plane. When the clothes treatment apparatus is a non-horizontal plane, the height direction of the clothes treatment apparatus is perpendicular to the installation surface of the clothes treatment apparatus. At this time, the height direction of the clothes treatment apparatus is not necessarily perpendicular to the horizontal plane.
[0075] Specifically, by arranging the gland 36 to clamp the upper end of the return air duct 35 between the bottom of the gland 36 and the side wall of the air inlet 302, specifically, the side wall of the air inlet 302 can refer to the circumferential side wall of the outer side edge of the air inlet 302. The clamping effect of the gland 36 on the return air duct 35 not only ensures the correct position of the return air duct 35, but also reduces the risk of loosening caused by vibration or air flow impact, so that a stable connection structure is formed between the return air duct 35 and the mounting seat 31.
[0076] Specifically, as a channel connecting the clothes treatment cavity 202 and the two-vessel cavity 301, by connecting the upper end of the return air duct 35 with the air inlet 302 of the mounting seat 31, and connecting the lower end of the return air duct 35 with the air inlet 302 of the mounting seat 31, when the clothes treatment apparatus needs to perform drying work, the air flow in the clothes treatment cavity 202 needs to pass through the return air port 204 and the air inlet 302, and then enter the two-vessel cavity 301. In this process, the air flow needs to be transported from bottom to top into the mounting seat 31 located above. By forming the inclined surface 304 on the top surface of the gland 36, in the first direction, the top surface of the gland 36 is inclined towards the side close to the center of the air inlet 302. The top surface of the gland 36 can be used to guide the air flow of the return air duct 35 to flow upwards through the air inlet 302 into the two-vessel cavity 301.
[0077] When the air flow enters the two-vessel cavity 301 through the air inlet 302, the air flow needs to diffuse from the periphery of the air inlet 302 into the two-vessel cavity 301. Due to the change in the direction of the air flow, the lint carried in the air flow will be retained on the top of the pressure cover due to the inertial effect. The top surface of the pressure cover 36, i.e., the surface extending along the peripheral direction of the air inlet 302, is obliquely arranged. The top surface of the pressure cover 36 is obliquely arranged toward the side close to the center of the air inlet 302, so that the lint retained on the periphery of the top of the pressure cover can receive the gravity component, and under the guidance of the top surface of the pressure cover 36, the lint slides along the oblique direction to the return air duct 35. Moreover, in the process of diffusing in the peripheral direction to the two-vessel cavity 301, the lint is blocked by the top surface of the pressure cover 36, and is more likely to be retained on the top of the pressure cover 36, and then slides toward the side close to the center of the air inlet 302. Most of the lint no longer enters the two-vessel cavity 301 with the air flow, but is effectively guided back into the return air duct 35, thereby greatly reducing the accumulation of lint in the two-vessel cavity 301, preventing the important components such as the evaporator 33 and the condenser 32 from being attached due to the air flow in the clothes treatment cavity 202 carrying a large amount of lint, and the clothes treatment device provided by the present application keeps the evaporator 33 and the condenser 32 clean, thereby ensuring the drying efficiency and working reliability.
[0078] In the prior art, lint is mainly blocked by adding a filter grid structure to the return air inlet 204, which may affect the air volume of the whole machine and thus reduce the drying efficiency. Compared with the prior art, the present application provides a pressure cover 36 with an oblique top surface arranged at the upper end of the return air duct 35. The top surface of the pressure cover 36 is obliquely arranged toward the side close to the center of the air inlet 302 in the direction from high to low in the first direction. When the air flow flows upward through the air inlet 302 from the return air duct 35, the air flow needs to diffuse from the periphery of the air inlet 302 into the two-vessel cavity 301. In this process, due to the change in the direction of the air flow, the lint carried in the air flow will be retained on the top of the pressure cover due to the inertial effect. In this way, the top surface of the pressure cover 36 can guide the air flow and the lint therein. Not only can the air flow be more smoothly diverted into the two-vessel cavity 301, but also the lint in the air flow can be effectively caused to fall back into the return air duct 35 along the top surface of the pressure cover 36. In this way, the air flow is not hindered by the filter grid structure in the prior art, the energy loss in the air circulation process is reduced, and thus the air volume and the drying efficiency of the whole machine are improved. At the same time, due to the guiding effect of the oblique arrangement of the top surface of the pressure cover 36, the lint is effectively collected and falls back into the return air duct 35, avoiding the deposition of the lint in the two-vessel cavity 301 and keeping the evaporator 33 and the condenser 32 clean.
[0079] It should be noted that the side wall of the mounting seat 31 arranged around the air inlet 302 also blocks the lint carried in the airflow. When the fan is started, the airflow direction changes due to the airflow flowing from the air inlet 302 to the two cavity 301, thereby causing the lint to be retained on the top of the gland.
[0080] As shown in Figure 2 and Figure 3 In some embodiments, the top of the drum assembly can be provided with an air return port 204. The air return port 204 can be located below the air inlet 302. By locating the air return port 204 below the air inlet 302, the airflow can flow from the air return port 204 to the air inlet 302 in the first direction, and under the action of gravity, the lint trapped on the inclined surface 304 of the gland 36 can fall back into the air return pipe 35 more quickly, and then fall back into the drum assembly 2 through the air return pipe 35.
[0081] Specifically, the lint falling back into the drum assembly 2 through the air return pipe 35 can flow to the drain valve assembly 12 through the drain port of the drum assembly 2, and then be discharged to the outside of the drum assembly 2.
[0082] As shown in Figure 5 In some embodiments, the air return port 204 and the air inlet 302 can be arranged opposite to each other. The air return pipe 35 can be vertically arranged between the air return port 204 and the air inlet 302. The opposite arrangement of the air return port 204 and the air inlet 302, and the vertical arrangement of the air return pipe 35 can simplify the airflow path, so that the lint trapped on the top surface of the gland 36 can more easily and quickly fall back into the drum assembly 2 through the air return pipe 35, avoiding the accumulation of lint in the air return pipe 35, affecting the subsequent drying process.
[0083] As shown in Figure 4 In some embodiments, the air return pipe 35 can be configured as a corrugated pipe. The air return pipe 35 configured as a corrugated pipe can form a flexible connection structure between the air return port 204 and the air inlet 302 through its wave structure. When the drum assembly 2 rotates and generates mechanical vibration, the elastic deformation of the corrugated pipe effectively reduces the vibration transmission rate, avoids the occurrence of resonance phenomenon, thereby significantly improving the overall operation stability of the equipment.
[0084] As shown in Figure 6 In some embodiments, the upper end of the air return pipe 35 can be provided with an upper turning edge 351. The upper turning edge 351 can be arranged above the circumferential edge of the air inlet 302. The gland 36 can press the upper turning edge 351 against the circumferential edge of the air inlet 302. The arrangement of the upper turning edge 351 can further increase the contact area between the gland 36 and the air return pipe 35, thereby achieving a close connection between the upper end of the air return pipe 35 and the mounting seat 31, and improving the connection strength between the air return pipe 35 and the mounting seat 31.

[0086] As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311. Figure 7 Figure 8 Specifically, the upper flange 351 of the upper end of the return air duct 35 is arranged in the upper flange 351 of the upper end of the return air duct 35, and cooperates with the limiting rib 311 formed by the circumferential edge of the air inlet 302. The medium pressure cover 36 is arranged above the limiting rib 311, so that the upper flange 351 can be tightly clamped between the medium pressure cover 36 and the limiting rib 311, further improving the stable connection between the return air duct 35 and the air inlet 302. Moreover, due to the close cooperation between the upper flange 351, the limiting rib 311 and the medium pressure cover 36, the return air duct 35 is not easy to loosen due to vibration or air flow impact during long-term use, which is conducive to maintaining smooth air flow. Figure 10 As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311.
[0087] As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311.
[0088] Figure 7 As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311.
[0089] Figure 11 Fig. 11 is a partial enlarged view of C of Fig. 10. Figure 10 As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311.
[0090] Figure 10 As shown in Figs. 8, 9 and 10, in some embodiments, the circumferential edge of the air inlet 302 can form a limiting rib 311. The medium pressure cover 36 can be arranged above the limiting rib 311, and the upper flange 351 can be clamped between the medium pressure cover 36 and the limiting rib 311. Figure 11
[0091] Specifically, the limiting ribs 311 can be formed by the mounting seat 31 upwardly protruding, and the limiting ribs 311 are internally formed with third connecting holes opening upwardly. Among them, the upwardly protruding part of the limiting ribs 311 is arranged in the second connecting hole 306, so that the upper flange 351 can be limited on the limiting ribs 311, and the third connecting hole is arranged corresponding to the first connecting hole 305, so that the connecting piece 37 can be inserted into the limiting ribs 311 after passing through the first connecting hole 305, and then the upper flange 351 clamped between the circumferential edge of the air inlet 302 and the upper pressing wall 363 of the pressure cover 36 is tightly fixed on the mounting seat. In this way, not only can the return air pipe 35 be reliably fixed on the circumferential side of the air inlet 302, but also the problem of insufficient sealing performance caused by directly arranging the opening on the mounting seat 31 and affecting the circulation efficiency of the air path can be avoided.
[0092] In some embodiments, the limiting ribs 311 can include a plurality of limiting ribs. The plurality of limiting ribs 311 can be arranged at intervals along the circumferential edge of the air inlet 302. Correspondingly, the first connecting hole 305 and the second connecting hole 306 can include a plurality of connecting holes, and the connecting piece 37 can include a plurality of connecting pieces to stably connect the pressure cover 36 and the upper flange 351 on the mounting seat 31.
[0093] As shown in Figure 9 , in some embodiments, the pressure cover 36 can include a guide rib 361. The guide rib 361 can be arranged protruding downwardly. The guide rib 361 can be internally formed with a guide groove 307, and the limiting rib 311 can be inserted into the guide groove 307 after passing through the second connecting hole 306 of the upper flange 351. Among them, the connecting piece 37 can be extended into the guide groove 307 and inserted into the third connecting hole of the limiting rib 311 after passing through the first connecting hole 305, further improving the connection strength between the pressure cover 36, the return air pipe 35 and the mounting seat 31, and effectively preventing the air flow from leaking at the connection.
[0094] As shown in Figure 5 and Figure 6 , in some embodiments, the pressure cover 36 can include an outer flange 362. The outer flange 362 is arranged at the edge of the upper pressing wall 363 away from the air inlet 302, and extends downwardly from the side of the upper pressing wall 363 of the pressure cover 36, so as to further press the upper flange 351 on the mounting seat 31.
[0095] As shown in Figure 5As shown, in some embodiments, the lower end of the return air pipe 35 can be sleeved with a fastening ring 38, which can be sleeved on the lower end of the return air pipe 35 and fix the lower end of the return air pipe 35 on the cylinder assembly. Specifically, the return air pipe 35 can be sleeved on the circumferential sidewall of the return air port 204 of the cylinder assembly 2 first, and then the fastening ring 38 is sleeved on the part of the return air pipe 35 located on the circumferential sidewall of the return air port 204, so that the lower end of the return air pipe 35 is clamped between the circumferential sidewall of the return air port 204 and the fastening ring 38, and then the lower end of the return air pipe 35 is fixedly sleeved on the cylinder assembly.
[0096] As shown in FIG. 1, in some embodiments, the cover 36 can include an upper pressing wall 363. The upper pressing wall 363 can be arranged above the circumferential edge of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the top surface of the cover 36. The top surface of the upper pressing wall 363 can be formed with an inclined surface 304. Figure 5 Figure 6 As shown, in some embodiments, the cover 36 can include an upper pressing wall 363. The upper pressing wall 363 can be arranged above the circumferential edge of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the top surface of the cover 36. The top surface of the upper pressing wall 363 can be formed with an inclined surface 304.
[0097] Specifically, the upper pressing wall 363 can extend outward along the circumferential side of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the inclined surface 304, and in the first direction from high to low, the inclined surface 304 is arranged to be inclined towards the side close to the center of the air inlet port 302. When the airflow flows upward and enters the mounting seat 31 through the air inlet port 302, the airflow is guided by the inclined surface 304, so that the dust can fall downward along the inclined surface 304 towards the center of the return air pipe 35.
[0098] As shown in FIG. 1, in some embodiments, the cover 36 can include an upper pressing wall 363. The upper pressing wall 363 can be arranged above the circumferential edge of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the top surface of the cover 36. The top surface of the upper pressing wall 363 can be formed with an inclined surface 304. Figure 6
[0099] Specifically, the upper pressing wall 363 can extend outward along the circumferential side of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the inclined surface 304, and in the first direction from high to low, the inclined surface 304 is arranged to be inclined towards the side close to the center of the air inlet port 302. When the airflow flows upward and enters the mounting seat 31 through the air inlet port 302, the airflow is guided by the inclined surface 304, so that the dust can fall downward along the inclined surface 304 towards the center of the return air pipe 35. Specifically, the upper pressing wall 363 can extend outward along the circumferential side of the air inlet port 302. The top surface of the upper pressing wall 363 is configured as the inclined surface 304, and in the first direction from high to low, the inclined surface 304 is arranged to be inclined towards the side close to the center of the air inlet port 302. When the airflow flows upward and enters the mounting seat 31 through the air inlet port 302, the airflow is guided by the inclined surface 304, so that the dust can fall downward along the inclined surface 304 towards the center of the return air pipe 35.
[0100] In some embodiments, the inclined surface 304 can be arranged circumferentially along the top of the cover 36.
[0101] As shown in Figure 6 some embodiments, the plane extending from the inclined surface 304 towards the side away from the inner flange 364 is the first reference plane, the plane perpendicular to the first direction is the third reference plane, and the included angle A between the first reference plane and the third reference plane is less than 30°. By setting the included angle A in the range of 0° < A < 30°, the lint can be effectively separated under the action of gravity and flow back to the return air duct 35, while the resistance of the air flow is reduced, thereby improving the air volume and drying efficiency.
[0102] It should be noted that the plane extending from the inclined surface 304 towards the side away from the inner flange is taken as the first reference plane. Further, the first reference plane is a straight plane away from the bending connection of the inner flange. Please refer to Figure 6 , where M1 represents the first reference plane, M2 represents the third reference plane, and the included angle between M1 and M2 is A.
[0103] Since the horizontally arranged plane cannot effectively separate the lint by gravity, the lint will stay on the plane, and even possibly enter the two-device cavity 301 along with the air flow, affecting the efficiency of the evaporator 33 and the condenser 32. Therefore, the included angle A is set to be greater than 0°. The included angle A between the first reference plane and the third reference plane can be less than 30°. Since the included angle is too large, the lint can be quickly carried into the return air duct 35 under the action of the air flow, but at the same time, it will hinder the smooth flow of the air flow, thereby affecting the overall drying efficiency. By setting the included angle A to be less than 30°, the blocking and filtering effects of the lint can be maintained, and at the same time, the smoothness of the air flow circulation between the clothes treatment cavity 202 and the two-device cavity 301 can be maintained.
[0104] When the included angle A is greater than 30°, and as the included angle A increases, the air flow will encounter greater resistance when passing through the inclined surface 304, thereby increasing the energy loss and easily leading to a decrease in air volume and affecting the drying efficiency.
[0105] As shown in Figure 6 some embodiments, the bending connection 365 between the inner side of the inclined surface 304 and the upper end of the inner flange 364 can be a circular arc transition. By setting the bending connection 365 between the inclined surface 304 and the upper end of the inner flange 364 as a circular arc transition, the lint falling along the inner flange 364 from the lower end of the inclined surface can be effectively guided to fall back into the return air duct 35, and at the same time, the vortex and resistance generated by the air flow at the connection between the inclined surface 304 and the inner flange 364 can be reduced, which is conducive to maintaining the smoothness of the air flow at the communication between the mounting seat 31 and the drum assembly 2.
[0106] As shown in Figure 7 and Figure 8As shown, in some embodiments, the inner flange 364 can be annular. In this way, the inner flange 364 can be arranged around the peripheral edge of the air inlet 302, forming a continuous closed structure. This allows most of the lint carried by the airflow as it flows through the inner flange 364 from all directions to fall back into the return air duct 35 under the guidance of the inclined surface 304. Furthermore, since the inner flange 364 is nested within the inner surface 308 of the air inlet 302, the annular inner flange 364 can also reduce the wind resistance generated when the airflow passes through it, maintaining high efficiency in airflow circulation.
[0107] In some other embodiments, the inner flange 364 may be a closed polygonal structure.
[0108] Figure 12 for Figure 7 A cross-sectional view; Figure 13 for Figure 12 A partial schematic diagram.
[0109] like Figure 12 and Figure 13 As shown, in some embodiments, the inner surface 308 of the inner flange 364 can be inclined towards the center of the air inlet 302 in a direction from high to low along the first direction. By inclining the inner surface 308 of the inner flange 364, the inclined inner surface 308 can not only effectively guide the lint entrained in the airflow, but also further guide the lint on the side of the upper pressure wall 363 to slide down the inner flange 364 towards the bottom of the return air duct 35, preventing lint from accumulating on one side of the upper pressure wall 363 and thus avoiding the problem of lint entering the two chambers 301 with the airflow and adhering to the surfaces of the evaporator 33 and condenser 32.
[0110] like Figure 13 As shown, in some embodiments, a straight line passing through any point on the inner surface 308 of the inner flange 364 and extending downward along the inner surface 308 is used as a reference line, and a plane perpendicular to the mounting surface of the garment processing equipment is used as a second reference surface. The angle B between the reference line and the second reference surface is less than 30°.
[0111] It should be noted that the reference line is a straight line extending downwards from a point on the inner surface 308 of the inner flange 364. In other words, the direction of the straight line represented by the reference line depends on the specific shape and tilt angle of the inner flange 364. The second reference surface is a plane perpendicular to the mounting surface of the garment processing equipment. When the mounting surface of the garment processing equipment is a horizontal plane, the second reference surface is perpendicular to the mounting surface of the garment processing equipment, that is, a vertical plane perpendicular to the horizontal plane. Specifically, as shown... Figure 6 In the middle, in a cross-section along the axial direction of the gland, L1 is indicated as the reference line and M3 is indicated as the second reference plane. The included angle between L1 and M3 is B.
[0112] In the present embodiment, by setting the included angle between the inner surface 308 of the inward flange 364 and the vertical surface to be within the range of 0° < B < 30°, the inner surface 308 of the inward flange 364 is arranged to be more inclined toward the side of the vertical surface, so that in the process of the air flow flowing from bottom to top, the lint and the like carried in the air flow can more easily deposit on the inward flange 364 and more smoothly slide into the return air duct 35 in the direction of being inclined toward the center of the return air duct 35 along the inclined inner surface 308. The inward flange 364 can work together with the upper pressing wall 363 to enable the lint in the air flow to be more effectively collected and guided into the return air duct 35, and also to avoid forming a large air resistance to the air flow, thereby maintaining the efficiency of air circulation.
[0113] It should be noted that when the included angle B is greater than 30°, and as the included angle B increases, the air flow will encounter greater resistance when passing through the inward flange 364, which can easily cause the air flow to generate turbulence or vortex when passing through the inward flange 364, not only causing noise but also possibly causing the air volume to decrease and affecting the drying efficiency.
[0114] As shown in FIG. 8, in some embodiments, the inner surface 308 of the inward flange 364 can be in the shape of an open gradually expanding horn in the direction from high to low along the first direction. Figure 12
[0115] As shown in FIG. 8, in some embodiments, the mounting seat 31 can be provided with a filter portion 312. The filter portion 312 can be arranged on the periphery of the air inlet 302 and at the communication between the air inlet 302 and the two cavity chambers 301. The filter portion 312 can be arranged higher than the inclined surface 304. Figure 5 By arranging the filter portion 312 on the periphery of the air inlet 302 and at the communication between the air inlet 302 and the two cavity chambers 301, it can be ensured that the air flow must pass through the filter portion 312 before entering the two cavity chambers 301, and the filter portion 312 can further block the lint carried in the air flow flowing from the air inlet 302 toward the two cavity chambers 301, thereby more effectively removing the lint.
[0116] As shown in FIG. 8, further, since the filter portion 312 is arranged higher than the inclined surface 304 and close to the air inlet 302, when the lint in the air flow flows through the filter portion 312, it can be blocked on the side of the filter portion 312 close to the gland 36, and when the lint accumulates, it can fall under the action of gravity onto the upper pressing wall 363 below, and then flow toward the return air duct 35 along the inclined surface 304 of the upper pressing wall 363 and the inner surface 308 of the inward flange 364, and finally fall back into the drum assembly 2 and be discharged to the outside of the clothes treatment apparatus through the drain valve assembly 12.
[0117] Figure 5 As shown in FIG. 8, further, since the filter portion 312 is arranged higher than the inclined surface 304 and close to the air inlet 302, when the lint in the air flow flows through the filter portion 312, it can be blocked on the side of the filter portion 312 close to the gland 36, and when the lint accumulates, it can fall under the action of gravity onto the upper pressing wall 363 below, and then flow toward the return air duct 35 along the inclined surface 304 of the upper pressing wall 363 and the inner surface 308 of the inward flange 364, and finally fall back into the drum assembly 2 and be discharged to the outside of the clothes treatment apparatus through the drain valve assembly 12.
[0118] like Figure 5 As shown, in some embodiments, the filter section 312 can be configured as a grid structure. Specifically, the filter section 312 can be composed of multiple spaced-apart ribs 3121, with air passages 3122 formed between adjacent ribs 3121, allowing airflow to smoothly flow into the two chambers 301. The grid structure can further reduce resistance to airflow, effectively trapping lint without affecting the efficiency of airflow circulation.
[0119] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
