[0035] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0036] In the description of the embodiments of the present application, it should be noted that the terms "top", "bottom", "upper", "lower" and the like indicate positions or location relationships based on the attached Figure 4 The orientation or position relationship shown, where "height direction" refers to Figure 4 The "top and bottom directions" shown are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] See also Figures 2 to 5 The embodiment of the present application provides a heat exchanger for a clothes processing device. The clothes processing device can at least be used to dry clothes.

[0038] The embodiment of the present application also provides a clothes processing device, which can at least be used for drying clothes, and specifically includes a base 10 and a heat exchanger 32 provided in the embodiment of the present application.

[0039] The base 10 is provided with two-device storage areas 10 a , and the heat exchanger 32 is disposed in the two-device storage areas 10 a .

[0040] The clothes treating device has an air circulation channel, and the air flow in the air circulation channel dries the clothes.

[0041] It should be noted that the specific type of the clothes processing device is not limited here, as long as it can be used to dry clothes, for example, it can be a clothes dryer or a washer-dryer. The embodiment of the present application is described by taking the clothes processing device as a washer-dryer as an example.

[0042] The washer-dryer can wash and dry clothes. The washer-dryer includes a frame, a washing device, a drying device and a base 10. The frame is the main supporting structure, which is used for fixing and supporting other parts of the washer-dryer; the washing device is fixed to the frame, used for washing clothes, and a washing cavity for accommodating clothes is formed inside; the drying device is fixed to the frame, and is preferably arranged above the washing device. The drying device is used for drying washed clothes, and a clothes processing cavity is formed inside. The base 10 is arranged between the washing device and the drying device, and is fixedly connected to the frame.

[0043] The clothes drying device comprises: a clothes drying drum, a front support and a door body. A clothes processing chamber for accommodating clothes is formed inside the clothes drying drum; the front support is fixed to the frame and is used to support the clothes drying drum; and a clothes taking-in and putting-out opening communicating with the clothes processing chamber is arranged on the front support, through which clothes can be taken-in and put-out into the clothes processing chamber; the door body is connected to the frame and / or the front support, and the door body can reciprocate relative to the frame to close or open the clothes taking-in and putting-out opening.

[0044] See also Figures 3 to 5 The embodiment of the present application also provides a heat pump system. The heat pump system 30 includes a heat exchanger 32 provided in the embodiment of the present application. The number of the heat exchangers 32 is two, one of the heat exchangers 32 is an evaporator, and the other heat exchanger 32 is a condenser.

[0045] It should be noted that the evaporator, the condenser and the compressor 31 constitute a part of the heat pump system 30, that is, the clothing processing device of the embodiment of the present application uses heat pump technology to dry clothing.

[0046] The working principle of the heat pump system 30 is as follows: the compressor 31 sucks in low-pressure gaseous refrigerant, which is discharged at high pressure after being compressed by the compressor 31. The discharged high-pressure refrigerant enters the condenser, is cooled by the air at room temperature, and condenses into a high-pressure liquid (at the same time, transferring heat to the surrounding air). In other words, the air around the condenser will be heated and heated up; the high-pressure liquid refrigerant flows through the capillary tube for throttling and decompression, and becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporator. The liquid refrigerant evaporates and cools in the evaporator (at the same time, absorbing heat from the surrounding air). In other words, the air around the evaporator will be cooled and cooled down, and the low-pressure gaseous refrigerant generated will be sucked in by the compressor 31 again and pressurized. This cycle repeats itself continuously to achieve heat exchange. It should be noted that the capillary tube mentioned above can also be replaced by an expansion valve.

[0047] The working process and drying principle of the clothing processing device of the embodiment of the present application are as follows: the dry hot air flow in the air circulation channel enters the clothing processing chamber from the downstream of the air circulation channel along the air flow direction. In the clothing processing chamber, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs moisture in the clothes, and becomes a humid hot air flow. The humid hot air flow flows through the evaporator and the condenser in sequence. In the process of flowing through the evaporator, the humid hot air flow is condensed and dehumidified by the evaporator to form a low-temperature dry air flow. The low-temperature dry air flow is heated to a dry hot air flow when passing through the condenser. The dry hot air flow enters the clothing processing chamber again from the downstream of the air circulation channel, and the cycle runs in this way to achieve continuous and efficient drying of clothes.

[0048] The heat pump type clothing processing device realizes high utilization of energy and low energy consumption. At the same time, the drying temperature of the heat pump system 30 is much lower than the heating temperature of the electric heating element, thereby ensuring the drying quality of the clothing.

[0049] In actual use, since the outer parts of the clothes drying drum and the washing drum fixedly arranged above and below are both round, there is a space left at the edge of the base 10. Figures 1 to 3 A two-device storage area 10a is provided at the edge of the base 10, and the heat exchanger 32 is arranged in the two-device storage area 10a. In this way, the heat exchanger 32 can be arranged in the vacant space as much as possible, which not only meets the assembly requirements, but also makes full use of the space in the frame, thereby reducing the installation height of the cylinder assembly.

[0050] The two-device storage area 10a is located on the air circulation channel, and the heat exchanger 32 is arranged in the two-device storage area 10a. The airflow in the air circulation channel flows through the evaporator and the condenser.

[0051] For example, see Figure 1 , Figure 2 and Figure 6 The base 10 includes a base body 11 and a cover body 12. The cover body 12 is covered on the base body 11 and is surrounded by the base body 11 to form a two-device storage area 10a. The two ends of the heat exchanger 32 along the height direction are clamped between the cover body 12 and the base body 11.

[0052] The two ends of the heat exchanger 32 along the height direction are clamped between the cover body 12 and the base body 11. In this way, the cover body 12 and the base body 11 can clamp the two ends of the heat exchanger 32 along the height direction. The cover body 12 and the base body 11 can press the heat exchanger 32 in the two-device storage area 10a, so that the airflow in the airflow circulation channel can flow through the fins 3213 of the heat exchanger 32 instead of passing through the gap between the heat exchanger 32 and the cover body 12 and the base body 11, thereby improving the heat exchange efficiency.

[0053] See also Figures 2 to 5 The heat exchanger 32 includes a heat exchange body 321 and a cover plate 322. The heat exchange body 321 includes a heat exchange area 321a and a non-heat exchange area 321b located at at least one end of the heat exchange area 321a in the height direction. The cover plate 322 is provided at the end of the heat exchange body 321 in the height direction and shields the non-heat exchange area 321b.

[0054] The heat exchange body 321 includes a heat exchange area 321a provided with fins 3213. In this way, when the airflow in the airflow circulation channel flows through the heat exchange area 321a, the airflow can exchange heat with the fins 3213 of the heat exchange area 321a, which is beneficial to sufficient heat exchange between the airflow and the heat exchange body 321 and improves the heat exchange efficiency.

[0055] The non-heat exchange area 321b is not provided with fins 3213. Thus, when the airflow in the airflow circulation channel flows through the non-heat exchange area 321b and flows through the heat exchange body 321, the airflow cannot fully exchange heat with the heat exchange body 321, thereby reducing the heat exchange efficiency.

[0056] The non-heat exchange area 321b is located at at least one end of the heat exchange area 321a along the height direction, which means that the non-heat exchange area 321b can be located at one end of the heat exchange area 321a along the height direction (that is, the non-heat exchange area 321b can be located at the top of the heat exchange area 321a or at the bottom of the heat exchange area 321a), or it can be located at both ends of the heat exchange area 321a along the height direction (that is, the non-heat exchange area 321b is formed at both ends of the heat exchange body 321 along the height direction).

[0057] The cover plate 322 is provided at the end of the heat exchange body 321 and shields the non-heat exchange area 321b. By providing the cover plate 322, on the one hand, it can be used to press the heat exchange body 321, and on the other hand, it can be used to shield the non-heat exchange area 321b, so as to avoid the airflow in the air circulation channel from passing through the non-heat exchange area 321b and passing through the heat exchanger 32, and instead, the airflow in the air circulation channel passes through the heat exchange area 321a and passes through the heat exchanger 32.

[0058] For example, in some implementations, see Figure 4 The heat exchange body 321 includes a plurality of heat exchange tubes 3211, a plurality of connecting elbows 3212 and fins 3213. Each heat exchange tube 3211 extends in the height direction and is arranged in a direction perpendicular to the height direction. The heat exchange tubes 3211 are connected by connecting elbows 3212, that is, the connecting elbows 3212 are connected to the top of the heat exchange tubes 3211, and the fins 3213 are connected between the heat exchange tubes 3211, which is conducive to heat transfer.

[0059] It is understandable that above each heat exchange tube 3211, at least part of the area where the connecting elbow 3212 is provided is not conducive to the installation of the fin 3213, and thus, the area where the fin 3213 is not provided is the non-heat exchange area 321b.

[0060] The heat exchanger 32 provided in the embodiment of the present application includes a heat exchange body 321 and a cover plate 322. The heat exchange body 321 includes a heat exchange area 321a and a non-heat exchange area 321b located at least at one end of the heat exchange area 321a in the height direction. The cover plate 322 is covered at the end of the heat exchange body 321 in the height direction and blocks the non-heat exchange area 321b. In this way, by setting the cover plate 322 to block the non-heat exchange area 321b, the airflow in the airflow circulation channel can flow through the heat exchange area 321a of the heat exchange body 321 instead of passing through the non-heat exchange area 321b, so that the airflow in the airflow circulation channel can exchange heat with the fins 3213 of the heat exchange area 321a, thereby improving the heat exchange efficiency and drying performance. In addition, by setting the cover plate 322 to cover the end of the heat exchange body 321 in the height direction, it is conducive to better pressing and fixing the heat exchange body 321.

[0061] In some embodiments, see Figures 3 to 5 The cover plate 322 includes a body 322a and a baffle plate 322b connected to the body 322a. The body 322a is covered at the end of the heat exchange body 321. The baffle plate 322b shields the non-heat exchange area 321b.

[0062] For example, see Figure 5 The body 322a and the baffle 322b are an integrated structure, for example, an integrated injection molding. The integrated body 322a and the baffle 322b can reduce the number of parts, reduce assembly time, and improve assembly efficiency.

[0063] Of course, the body 322a and the baffle 322b may also be a split structure, which is conducive to forming a desired structure.

[0064] The body 322a is disposed on the end of the heat exchange body 321 along the height direction. In other words, the function of pressing the heat exchange body 321 can be realized by the body 322a.

[0065] The baffle 322b blocks the non-heat exchange area 321b. That is, the baffle 322b can be used to block the non-heat exchange area 321b, and to a certain extent, the airflow in the airflow circulation channel can be prevented from flowing through the non-heat exchange area 321b and the heat exchange body 321.

[0066] By setting the cover plate 322 to include a body 322a and a baffle 322b, the body 322a is covered at the end of the heat exchange body 321 along the height direction, and the baffle 322b shields the non-heat exchange area 321b. While the heat exchange body 321 is pressed, the function of shielding the non-heat exchange area 321b can also be realized, and the structure is simple.

[0067] In some embodiments, see Figures 2 to 5 The heat exchange area 321a is formed with a heat exchange channel, and baffles 322b are provided on both sides of the main body 322a along the extension direction of the heat exchange channel.

[0068] The heat exchange region 321a is formed with a heat exchange channel, and the fins 3213 are connected between the heat exchange tubes 3211 to form a heat exchange channel. When the airflow in the airflow circulation channel flows through the heat exchange channel, it exchanges heat with the fins 3213 of the heat exchange region 321a.

[0069] Baffles 322b are provided on both sides of the main body 322a along the extension direction of the heat exchange channel, that is, the baffles 322b on both sides of the cover plate 322 can be used to block the non-heat exchange area 321b on both sides along the extension direction of the heat exchange channel, further facilitating the airflow to flow through the heat exchange channel of the heat exchange area 321a and pass through the heat exchanger 32.

[0070] In some embodiments, the cover plate 322 is adapted to the shape of the surface of the heat exchanging body 321 .

[0071] The shape of the cover plate 322 is adapted to the surface of the heat exchange body 321, and the surface of the cover body 12 at least facing the upper surface of the heat exchange body 321 is adapted to the shape of the upper surface of the heat exchange body 321. This is conducive to the fit between the cover plate 322 and the surface of the heat exchange body 321, thereby facilitating the pressing of the heat exchange body 321.

[0072] In some embodiments, see Figure 2 and Figure 5 The upper surface of the heat exchange body 321 is stepped. The upper surface of the heat exchange body 321 has a plurality of first step surfaces 321c. The cover plate 322 has a plurality of second step surfaces 322c corresponding to each of the first step surfaces 321c.

[0073] That is to say, each second step surface 322 c corresponds to each first step surface 321 c one by one, which is further conducive to the surface fitting of the cover plate 322 and the heat exchange body 321 .

[0074] Of course, in other embodiments, the contact surfaces of the cover plate 322 and the heat exchange body 321 can be matching inclined surfaces at the same time, or matching curved surfaces at the same time.

[0075] In some embodiments, see Figure 3 and Figure 5 The cover plate 322 includes an upper cover plate 3221 and a lower cover plate 3222 . The upper cover plate 3221 is covered on the top end of the heat exchange body 321 , and the lower cover plate 3222 is covered on the bottom end of the heat exchange body 321 .

[0076] By setting the upper cover plate 3221 to cover the top of the heat exchange body 321, when the cover body 12 is covered on the base body 11, the cover body 12 and the base body 11 will squeeze the upper cover plate 3221, thereby squeezing the heat exchange body 321, which is beneficial to compacting the heat exchange body 321 and improving the heat exchange efficiency.

[0077] By setting the lower cover plate 3222 to cover the bottom end of the heat exchange body 321, when the cover body 12 is covered on the seat body 11, the cover body 12 and the seat body 11 will squeeze the lower cover plate 3222, thereby squeezing the heat exchange body 321, which is beneficial to compacting the heat exchange body 321 and improving the heat exchange efficiency.

[0078] Due to the problem of manufacturing process, the produced parts such as the base 10 and the heat exchange body 321 have size differences. The cover 12 and the seat 11 can sometimes press the heat exchange body 321 tightly, but sometimes cannot. When the heat exchange body 321 is not pressed tightly, the heat exchange efficiency will be reduced. By simultaneously providing the upper cover plate 3221 and the lower cover plate 3222, which are respectively covered at both ends of the heat exchange body 321 in the height direction, the problem that the cover 12 and the seat 11 cannot press the heat exchange body 321 tightly can be improved to a certain extent.

[0079] In some embodiments, see Figure 5 , the lower cover plate 3222 is provided with a drainage hole 3222b. When the heat exchanger 32 is an evaporator, the liquid refrigerant in the evaporator evaporates and cools in the evaporator (while absorbing heat from the surrounding air), that is, the air around the evaporator will be cooled and lowered in temperature. Therefore, in the process of the hot and humid air flow passing through the evaporator, the hot and humid air flow is condensed and dehumidified by the evaporator to form a low-temperature dry air flow, and condensed water will be generated at the same time. If the condensed water is deposited in the lower cover plate 3222, the air flow passing through may bring the condensed water into the drying chamber, thereby reducing the drying effect of the clothes. The lower cover plate 3222 of the embodiment of the present application is provided with a drainage hole 3222b, and the condensed water can be discharged from the lower cover plate 3222 through the drainage hole 3222b, which can avoid the situation where the air flow passing through brings the condensed water into the drying chamber to a certain extent.

[0080] In some embodiments, see Figure 3 and Figure 5 The cover plate 322 includes an upper cover plate 3221 , and the upper cover plate 3221 is covered on the top of the heat exchange body 321 .

[0081] Along the direction from the first end of the upper cover plate 3221 to the second end of the upper cover plate 3221 , at least a portion of the upper surface of the upper cover plate 3221 is lowered.

[0082] By setting at least part of the upper surface of the upper cover plate 3221 to be lowered, a clearance area for avoiding the barrel assembly is formed above the heat exchanger 32. In this way, the height of the installation position of the barrel assembly above the heat exchanger 32 is reduced, thereby reducing the height dimension of the clothing processing device, making the structure of the clothing processing device more compact. In addition, since the overall height of the clothing processing device is reduced, the convenience of use and operation and the overall aesthetics can be improved to a certain extent. Furthermore, by setting at least part of the upper surface of the upper cover plate 3221 to be lowered, it is helpful to design the heat exchanger 32 as large as possible within a limited space, increase the heat exchange area of ​​the heat exchanger 32, and thus improve performance.

[0083] In some embodiments, see Figure 3 and Figure 5 The upper cover plate 3221 includes at least one first mounting plane 3221a parallel to the horizontal plane. By setting the first mounting plane 3221a parallel to the horizontal plane, it is beneficial for the cover body 12 to fit with the surface of the first mounting plane 3221a, and a vertical force is generated on the heat exchanger 32, and the horizontal force component is reduced as much as possible, which can improve the possibility of lateral movement of the heat exchanger 32 to a certain extent, and can better fix the heat exchanger 32.

[0084] In some embodiments, see Figure 3 and Figure 5 The cover plate 322 includes a lower cover plate 3222 , which is covered on the bottom end of the heat exchange body 321 , and at least a portion of the upper surface of the lower cover plate 3222 is raised along a direction from a first end of the lower cover plate 3222 to a second end of the lower cover plate 3222 .

[0085] Along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, at least a portion of the upper surface of the lower cover plate 3222 is raised, that is, along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, the upper surface of the heat exchanger 32 close to the edge can be lower than the upper surface of the heat exchanger 32 away from the edge, so that an avoidance area for avoiding the cylinder assembly is formed under the heat exchanger 32.

[0086] In this way, the space below the heat exchanger 32 can be fully utilized, thereby reducing the height of the laundry processing device, making the structure of the laundry processing device more compact. In addition, since the overall height of the laundry processing device is reduced, the convenience of operation and the overall aesthetics can be improved to a certain extent.

[0087] In some embodiments, see Figure 3 and Figure 5The lower cover plate 3222 includes at least one second mounting plane 3222a parallel to the horizontal plane. By setting the second mounting plane 3222a parallel to the horizontal plane, it is beneficial for the surface of the seat body 11 to fit with the second mounting plane 3222a, and a vertical force is generated on the heat exchanger 32, and the horizontal force component is reduced as much as possible, which can improve the possibility of lateral displacement of the heat exchanger 32 to a certain extent, and can better fix the heat exchanger 32.

[0088] Exemplarily, the upper cover plate 3221 includes at least one first mounting plane 3221a parallel to the horizontal plane. The lower cover plate 3222 includes at least one second mounting plane 3222a parallel to the horizontal plane. The base 10 can be pressed onto the first mounting plane 3221a and the second mounting plane 3222a parallel to the horizontal plane at the upper and lower ends of the heat exchanger 32, that is, to generate a vertical force on the heat exchanger 32, and to reduce the horizontal force as much as possible, so as to better fix the heat exchanger 32, and avoid the first mounting plane 3221a and the second mounting plane 3222a being all inclined planes and unable to completely fix the heat exchanger 32, causing the clothing processing device to become loose after a long period of operation, resulting in resonance and abnormal noise.

[0089] By setting a first mounting plane 3221a and a second mounting plane 3222a which are both parallel to the horizontal plane, the heat exchanger 32 can be supported and pressed in a horizontal position, so that the heat exchanger 32 can be better fixed by the cover body 12 and the base body 11, and the heat exchanger 32 will not be unable to be completely fixed because the upper cover plate 3221 and / or the lower cover plate 3222 are all inclined or curved surfaces, causing the clothing processing equipment to become loose after long-term operation, resulting in resonance and abnormal noise. In addition, at least part of the upper surface of the upper cover plate 3221 is lowered, and at least part of the upper surface of the lower cover plate 3222 is raised, which can make full use of the space and is conducive to designing the heat exchanger 32 as large as possible within a limited space, thereby increasing the heat exchange area of ​​the heat exchanger 32 and improving performance. In some embodiments, please refer to Figure 3 and Figure 5, the number of the first mounting planes 3221a is multiple, and the upper cover plate 3221 is stepped. That is, the upper surface of the upper cover plate 3221 has multiple first mounting planes 3221a. An escape area for escaping the cylinder assembly is formed above the stepped heat exchanger 32. In this way, along the direction from the first end to the second end, while achieving the lowering of at least part of the upper surface of the upper cover plate 3221, the upper surface of the upper cover plate 3221 can also have multiple first mounting planes 3221a, which can be abutted against the cover body 12 through the multiple first mounting planes 3221a, that is, the upper surface of the upper cover plate 3221 is in planar contact with the cover body 12, that is, a vertical force is generated on the upper cover plate 3221, and the horizontal component force is reduced as much as possible. In this way, the heat exchanger 32 can be better installed in the two-device storage area 10a, which is conducive to the base 10 to better fix the heat exchanger 32 and reduce the shaking of the heat exchanger 32.

[0090] Exemplarily, the number of the first mounting planes 3221a is 4-8, for example, 4, 5, 6, 7 or 8.

[0091] The length of the first mounting plane 3221a is related to the length of the fin 3213. Each first mounting plane 3221a may correspond to a plurality of fins 3213, that is, a plurality of fins 3213 may be provided on each first mounting plane 3221a. The number of first mounting planes 3221a within this range is conducive to better pressing of the upper cover plate 3221 between the seat body 11 and the cover body 12, and will not interfere with the upper cylinder assembly.

[0092] In other embodiments, along the direction from the first end of the upper cover plate 3221 to the second end of the upper cover plate 3221, at least a portion of the upper surface of the upper cover plate 3221 is tilted downward so that at least a portion of the upper surface of the upper cover plate 3221 is lowered, thereby forming an avoidance area above the upper cover plate 3221 for avoiding the cylinder assembly.

[0093] In some other embodiments, along the direction from the first end of the upper cover plate 3221 to the second end of the upper cover plate 3221, at least a portion of the upper surface of the upper cover plate 3221 forms a downwardly concave arc surface, so that at least a portion of the upper surface of the upper cover plate 3221 is lowered, thereby forming an avoidance area above the upper cover plate 3221 for avoiding the cylinder assembly.

[0094] In some embodiments, the lower surface of the lower cover plate 3222 is stepped. The lower surface of the lower cover plate 3222 is stepped. In other words, the lower surface of the lower cover plate 3222 has a plurality of second mounting planes 3222a. A relief area for escaping the cylinder assembly is formed below the stepped lower cover plate 3222. In this way, along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, while achieving the elevation of at least part of the lower surface of the lower cover plate 3222, the lower surface of the lower cover plate 3222 can also have a plurality of second mounting planes 3222a, and can be abutted against the seat body 11 through the plurality of second mounting planes 3222a, that is, the lower surface of the lower cover plate 3222 is in planar contact with the seat body 11, that is, a vertical force is generated on the lower cover plate 3222, and the horizontal component of force is reduced as much as possible. In this way, the heat exchanger 32 can be better installed in the two-device storage area 10a, which is beneficial for the base 10 to better fix the heat exchanger 32 and reduce the shaking of the heat exchanger 32.

[0095] In some embodiments, along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, at least a portion of the lower surface of the lower cover plate 3222 is tilted upward, so that at least a portion of the lower surface of the lower cover plate 3222 is raised, thereby forming a avoidance area below the lower cover plate 3222 for avoiding the cylinder assembly.

[0096] In some embodiments, along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, at least a portion of the lower surface of the lower cover plate 3222 forms an upwardly concave arc surface, so that at least a portion of the lower surface of the lower cover plate 3222 is raised, thereby forming a avoidance area below the lower cover plate 3222 for avoiding the cylinder assembly.

[0097] In a specific embodiment, along the direction from the first end of the lower cover plate 3222 to the second end of the lower cover plate 3222, the lower cover plate 3222 includes a second mounting plane 3222a and an upwardly concave arc surface in sequence. The setting of the second mounting plane 3222a can better install the heat exchanger 32 in the two-device storage area 10a, which is beneficial for the base 10 to better fix the heat exchanger 32. The setting of the upwardly concave arc surface is beneficial for designing the heat exchanger 32 as large as possible within a limited space, thereby increasing the heat exchange area of ​​the heat exchanger 32 and improving performance.

[0098] In some embodiments, the clothes treating apparatus comprises a sealing member, and the sealing member is disposed between a surface of the cover plate along a height direction and the base.

[0099] The sealing member is attached to the top surface or the bottom surface of the cover plate 322. That is, the sealing member can be attached to the top surface of the upper cover plate 3221, or to the bottom surface of the lower cover plate 3222, or to the top surface of the upper cover plate 3221 and the bottom surface of the lower cover plate 3222.

[0100] The seal is sandwiched between the cover plate 322 and the base 10. The seal can be used to neutralize the size difference between the heat exchange body 321 and the base 10, and to a certain extent can improve the problem that the heat exchange body 321 cannot be pressed tightly due to the manufacturing size difference between the heat exchange body 321 and the base 10.

[0101] The seal is used to seal the gap between the cover plate 322 and the base 10 , which can prevent the airflow in the air circulation channel from passing through the gap between the cover plate 322 and the base 10 to a certain extent, and can further improve the sealing between the cover plate 322 and the base 10 .

[0102] It should be noted that the specific type of the sealing member is not limited here, and may be sponge, rubber or silicone, for example.

[0103] In some embodiments, the clothes processing device includes a frame and a compressor 31, the base 10 is disposed on the frame, the base 10 has an escape space, the compressor 31 is passed through the escape space, and is connected to the frame.

[0104] The specific structure of the escape space is not limited. In some embodiments, the escape space is a gap formed on one side of the base 10.

[0105] In other embodiments, the avoidance space may also be a through hole penetrating along the top and bottom directions.

[0106] The compressor 31 is arranged in the avoidance space and connected to the frame. That is to say, the weight of the compressor 31 is not carried by the base 10 in the laundry processing device of the embodiment of the present application, but is carried by the frame.

[0107] In one embodiment, the clothes processing device comprises a belt and a pulley, wherein the pulley is connected to a motor shaft of the motor, and the belt is wound around the circumference of the clothes drying drum and the pulley. That is, the motor can drive the clothes drying drum to rotate.

[0108] When the dryer is drying clothes, the motor can drive the fan and the pulley to rotate at the same time. The pulley drives the dryer to rotate. During the rotation of the dryer, the clothes are turned over and shaken in the clothes processing chamber, which can speed up the heat exchange between the clothes and the dry hot air flow.
