DETAILED DESCRIPTION

[0024] In the absence of conflict, the embodiments and technical features in the embodiments of the present application may be combined with each other, and the detailed descriptions in the specific implementation methods should be understood as explanations of the purpose of the present application and should not be regarded as improper limitations on the present application.

[0025] It should be noted that in the embodiments of the present application, the "front" and "rear" positions or positional relationships are based on Figure 1 , Figure 3 and Figure 4 The orientation or position relationship shown. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application. The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] An embodiment of the present application provides a clothing processing device, which includes a fin heat exchanger, a clothing processing chamber and an air duct, wherein the air duct is connected to the clothing processing chamber, and the fin heat exchanger is arranged in the air duct.

[0027] The clothes processing chamber is used to contain and process clothes. The way of processing clothes includes but is not limited to drying clothes.

[0028] The airflow in the clothes processing chamber can enter the air duct to perform heat exchange with the fin-type heat exchanger.

[0029] See also Figure 1 , Figure 3 and Figure 4 The fin heat exchanger includes a refrigerant tube 100 , a first fin group 200 and a second fin group 300 .

[0030] The refrigerant pipe 100 includes a joint 110 and a pipe group 120. The pipe group 120 includes a plurality of pipe bodies 121 extending along a first direction. The plurality of pipe bodies 121 of the pipe group 120 are sequentially arranged in a spaced relationship along a front-to-back direction. The pipe bodies 121 are connected through the joint 110 so that the refrigerant pipe 100 is a continuous pipeline. The airflow in the air duct flows from front to back through the plurality of pipe bodies 121. Specifically, the first direction intersects with the front-to-back direction.

[0031] In the present application, a continuous pipeline refers to a coil in which the refrigerant tube 100 extends in a tortuous manner. The refrigerant enters the refrigerant tube 100 from the refrigerant inlet 100a of the refrigerant tube 100, and can flow in the refrigerant tube 100 substantially along the extension direction of the refrigerant tube 100 and then flow out from the refrigerant outlet 100b of the refrigerant tube 100. Exemplarily, in the front-to-back direction, the port of the refrigerant tube 100 close to the front side is the refrigerant outlet 100b, and the port of the refrigerant tube 100 close to the rear side is the refrigerant inlet 100a.

[0032] See also Figure 1 , Figure 3 and Figure 4 The first fin group 200 includes a plurality of first fins 210 arranged at intervals along the first direction, and at least one tube body 121 of the tube group 120 is provided with the first fin group 200. At least one tube body 121 of the tube group 120 is provided with the first fin group 200 means: one tube body 121 of the tube group 120 may be provided with the first fin group 200. Alternatively, multiple tube bodies 121 of the tube group 120 may be provided with the first fin group 200.

[0033] Please continue reading Figure 1 , Figure 3 and Figure 4 The second fin group 300 includes a plurality of second fins 310 spaced apart along the first direction, and the heat exchange efficiency of the second fins 310 is higher than that of the first fins 210. At least one tube body 121 of the tube group 120 is provided with the second fin group 300, and the second fin group 300 is located behind the first fin group 200.

[0034] At least one tube body 121 of the tube group 120 is provided with the second fin group 300 means that one tube body 121 of the tube group 120 may be provided with the second fin group 300. Alternatively, multiple tube bodies 121 of the tube group 120 may be provided with the second fin group 300.

[0035] It should be understood that the second fin set 300 is located behind the first fin set 200, that is, the second fin set 300 is arranged on the tube body 121 of the tube set 120 located behind the first fin set 200. The first fin set 200 and the second fin set 300 are not arranged on the same tube body 121 of the same tube set 120. The same tube body 121 of the same tube set 120 can only be provided with one of the first fin set 200 and the second fin set 300. However, different tube bodies 121 of the same tube set 120 can all be provided with the first fin set 200; or, different tube bodies 121 of the same tube set 120 can all be provided with the second fin set 300.

[0036] The finned heat exchanger in the related art uses a single type of fins, that is, fins with the same heat exchange efficiency. However, when the airflow flows through the refrigerant tube from front to back, the temperature difference between the airflow and the refrigerant tube becomes smaller and smaller from front to back. If all fins of the same heat exchange efficiency are used, the heat exchange efficiency of the heat exchanger will become worse and worse from front to back. If all fins are replaced with fins with higher heat exchange efficiency in order to improve the heat exchange efficiency, there will be problems such as increased production costs and / or increased wind resistance.

[0037] The clothing processing device provided in the embodiment of the present application, considering that the temperature difference between the refrigerant in the refrigerant pipe 100 and the airflow flowing therethrough gradually decreases from front to back, the second fin 310 with relatively higher heat exchange efficiency is arranged behind the first fin 210 with relatively lower heat exchange efficiency, that is, the second fin group 300 is arranged on the tube body 121 of the tube group 120 located behind the first fin group 200, so that the first fin 210 can be used if the temperature difference in the front area of ​​the fin type heat exchanger is large, and the heat exchange efficiency is appropriate and the cost is low; the second fin 310 can be used if the temperature difference in the rear area of ​​the fin type heat exchanger is small, so as to improve the heat exchange efficiency without significantly increasing the cost or increasing the wind resistance. In this way, under the condition of improving the drying performance of the clothing processing device, the wind resistance of the air duct and / or the cost of the clothing processing device is not significantly increased.

[0038] For example, in some embodiments, the tube body 121 may be a straight tube.

[0039] Clothes processing equipment includes but is not limited to clothes dryers or clothes care cabinets, etc.

[0040] In some embodiments, the laundry processing chamber cannot rotate. In other words, the laundry processing chamber remains fixed. During the laundry processing process, the laundry processing chamber remains stationary. For example, if the laundry processing device is a laundry care cabinet, the laundry processing chamber of the laundry care cabinet cannot rotate.

[0041] For example, in some embodiments, the clothing care cabinet further includes a cabinet body, a cabinet door, and a clothes drying device disposed in the cabinet body and used to hang clothes. The cabinet body has a clothing processing chamber and a take-in and put-out port communicating with the clothing processing chamber, and the cabinet door is used to selectively open or close the take-in and put-out port; the clothes drying device is disposed at the upper part of the clothing processing chamber. In this embodiment, the clothes are hung on the clothes drying device and the cabinet door is closed, that is, the clothes will not roll during the drying or cleaning process, thereby reducing damage to the clothes, and the clothes will not be wrinkled or tangled after drying.

[0042] In some embodiments, the laundry processing chamber can rotate. In this way, during the rotation of the laundry processing chamber, the laundry processing chamber drives the laundry to move. This can improve the laundry processing efficiency. Taking the laundry processing device as a dryer as an example, the laundry processing chamber of the dryer can rotate.

[0043] Exemplarily, in some embodiments, the clothes processing device includes a rotatable clothes drum, and the space in the clothes drum is a clothes processing chamber. In this way, during the rotation of the clothes drum, the clothes drum drives the clothes in the clothes processing chamber to move, thereby improving the clothes processing efficiency.

[0044] The rotation axis of the clothes drum may be in a horizontal direction. That is, the clothes treating apparatus may be a drum type clothes treating apparatus.

[0045] The rotation axis of the clothes drum can be along an inclined direction. It can be understood that the inclined direction is that the extension direction of the rotation axis is located between the horizontal direction and the vertical direction.

[0046] In some embodiments, the clothes holding drum is substantially cylindrical.

[0047] In some embodiments, the laundry care cabinet further comprises a box body and a door body, wherein the laundry drum is located in the box body, the box body has a laundry inlet communicated with the laundry processing chamber, and the door body selectively opens or closes the laundry inlet. A user puts or takes laundry into or out of the laundry drum through the laundry inlet.

[0048] The box body may be roughly in the shape of a hexahedron, for example, in the shape of a cube or a cuboid.

[0049] In one embodiment, the clothes holding drum may be a single-drum structure, that is, the clothes processing device has only one drum body, the clothes holding drum.

[0050] In another embodiment, the clothes processing device comprises an outer barrel, and the outer barrel is sleeved outside the clothes holding drum.

[0051] In some embodiments, there are multiple tube groups 120, and the multiple tube groups 120 are arranged at intervals along the second direction, and each tube body 121 is connected through a joint 110 so that the refrigerant tube 100 is a continuous pipeline. In other words, two tube bodies 121 in the same tube group 120 are connected through the joint 110, and two tube bodies 121 in different tube groups 120 are connected through the joint 110. The refrigerant tube 100 is a three-dimensional coil.

[0052] It should be noted that the first direction and the front-rear direction are both perpendicular to the second direction.

[0053] In some embodiments, the number of tube groups 120 is one group, and two adjacent tube bodies 121 in the tube group 120 along the front-to-back direction are connected through the joint 110 to make the refrigerant tube 100 a continuous pipeline. In other words, the refrigerant tube 100 is generally a planar winding structure perpendicular to the second direction.

[0054] In one embodiment, please refer to Figure 1 and Figure 4 , the first fin 210 is a flat sheet 101 , and the second fin 310 is a window sheet 102 .

[0055] The flat sheet 101 is a flat fin that has not been punched.

[0056] The window plate 102 is a fin in which slots are formed by a process such as a punching process.

[0057] Since the flat sheet 101 has flat surfaces on both sides in the thickness direction and has no slits, when the airflow flows through the planes on both sides in the thickness direction of the flat sheet 101, the boundary layer of the airflow generates a large shear force, which will cause resistance and loss to the flow of the airflow, making the airflow tend to move away from the planes on both sides in the thickness direction of the flat sheet 101; while the window sheet 102 has slits running through the two planes in the thickness direction, and the airflow can flow through the slits, thereby interrupting the boundary layer of the airflow and effectively reducing the heat exchange dead zone. Therefore, the heat exchange efficiency of the window sheet 102 is higher than that of the flat sheet 101.

[0058] If the single type of fin in the related technology is a flat fin, the heat exchange efficiency of the fin heat exchanger is relatively low. If all the flat fins are replaced with window fins, although the window fins can improve the overall heat exchange efficiency of the heat exchanger, since the window fins need to be processed such as stamping, the cost of the window fins is usually higher than that of the flat fins, and the wind resistance of the window fins is greater than that of the flat fins. In addition, since clothes will produce lint during the drying process, the lint will easily adhere to the window fins as it enters the air duct with the air flow, causing the lint to concentrate on the window fins, further increasing the resistance in the air duct. It is also troublesome to clean the lint attached to the window fins, affecting the user experience.

[0059] The embodiment of the present application adopts a combination of a flat sheet 101 and a window sheet 102. On the one hand, it can take into account both the heat exchange effect and the production cost; on the other hand, the flat sheet 101 is located in front of the window sheet 102, and the airflow first contacts the flat sheet 101 and then contacts the window sheet 102. The hair debris will first adhere to the flat sheet 101, thereby reducing or even eliminating the hair debris attached to the window sheet 102, which can avoid significantly increasing the air duct resistance and the difficulty of cleaning the hair debris.

[0060] In one embodiment, the first fin 210 is a flat sheet 101, and the second fin 310 is a corrugated sheet.

[0061] The corrugated sheet refers to a fin that has been processed, such as stamping, to form an undulating shape. The corrugated sheet has a wave-like shape.

[0062] The surfaces of the corrugated sheet on both sides along the thickness direction are undulating curved surfaces. The curved surfaces can thin the boundary layer of the airflow relative to the plane of the flat sheet 101 . Therefore, the heat exchange efficiency of the corrugated sheet is greater than that of the flat sheet 101 .

[0063] In one embodiment, the first fin 210 is a corrugated sheet, and the second fin 310 is a window sheet 102. Since the boundary layer of the airflow on the corrugated sheet is thicker than that on the window sheet 102, the heat exchange efficiency of the window sheet 102 is greater than that of the corrugated sheet.

[0064] In one embodiment, a plurality of tube bodies 121 of a tube group 120 may be provided with the same first fin group 200. That is, a plurality of tube bodies 121 of a tube group 120 may be provided on the same first fin 210. In other words, a plurality of tube bodies 121 of a tube group 120 arranged in the front-to-back direction may be provided on a first fin 210. In this way, the size of the first fin 210 in the front-to-back direction is larger, and the heat exchange surface area of ​​the first fin 210 may be increased.

[0065] In another embodiment, each tube body 121 of a tube group 120 may be provided with a first fin group 200. That is, two first fins 210 on two adjacent tube bodies 121 of a tube group 120 along the front-to-back direction are separated. Such a design facilitates the insertion of tubes in the first fins 210.

[0066] In one embodiment, multiple tube bodies 121 of a tube group 120 can be provided with the same second fin group 300. In other words, multiple tube bodies 121 of a tube group 120 can be passed through the same second fin 310. In other words, multiple tube bodies 121 of a tube group 120 arranged in the front-to-back direction can be provided on a second fin 310. In this way, the size of the second fin 310 in the front-to-back direction is larger, and the heat exchange surface area of ​​the second fin 310 can be increased.

[0067] In another embodiment, each tube body 121 of a tube group 120 may be provided with a second fin group 300. That is, the two second fins 310 on two adjacent tube bodies 121 of a tube group 120 along the front-to-back direction are separated. Such a design facilitates the second fins 310 to pass through the tubes.

[0068] In some embodiments, the first fin 210 and the second fin 310 are both formed with a tube hole 1021 b , and the tube body 121 can be inserted into the tube hole 1021 b .

[0069] In one embodiment, please refer to Figure 2 The window sheet 102 includes a substrate 1021 and louvers 1022. The substrate 1021 is formed with a window area 1021a and a tube hole 1021b for penetrating the tube body 121. The window area 1021a has a slit that runs through both sides of the substrate 1021 in the thickness direction. The louvers 1022 are arranged in the slit. The louvers 1022 can play a guiding role. The airflow can enter the slit under the guiding role of the louvers 1022, thereby interrupting the interface layer formed by the airflow on the substrate 1021.

[0070] In one embodiment, please refer to Figure 2 The substrate 1021 has a plurality of tube holes 1021b and a plurality of window areas 1021a, some of the tube holes 1021b are arranged at intervals along the length direction of the substrate 1021 to form a row of hole groups, a window area 1021a is arranged between two adjacent tube holes 1021b in a row of hole groups, and the plurality of row of hole groups are arranged at intervals along the width direction of the substrate 1021. In this way, a plurality of tube bodies 121 of a tube group 120 can be passed through a window sheet 102.

[0071] The finned heat exchanger in the related art was tested. The finned heat exchanger in the related art uses flat plates, and the tube group includes more than 5 tube bodies arranged at intervals in the front-to-back direction. The multiple tube bodies of the tube group are defined as the 1st row, the 2nd row, the 3rd row, the 4th row, the 5th row, the kth row, etc. from front to back. After testing, the heat exchange efficiency of the 1st to 2nd row is more than 80%, the heat exchange efficiency of the 3rd row is about 60%, the heat exchange efficiency of the 4th to 5th row heat exchangers is about 30%, and the heat exchange efficiency of the remaining rows after the 5th row is less than 10%.

[0072] In view of this, in order to make the heat exchange efficiency of tube bodies 121 of different rows suitable and consistent, in one embodiment, the number of tube bodies 121 of the tube group 120 is not more than 3, and in the front-to-back direction, the tube bodies 121 of the last row of the tube group 120 are provided with the second fin group 300, and the remaining tube bodies 121 of the tube group 120 are all provided with the first fin group 200. In other words, two types of fin combinations are used, and when the number of tube bodies 121 of the tube group 120 is two or three, the tube bodies 121 of the last row of the tube group 120 are penetrated on the second fin 310, and the tube bodies 121 of the first row or the first two rows of the tube group 120 are penetrated on the first fin 210. In this way, the heat exchange effect of the fin-type heat exchanger can be enhanced, and the excessive air duct resistance caused by the use of all second fins 310, such as window sheets 102, can be effectively avoided. In addition, the first row or the first two rows of the heat exchanger use the first fins 210, such as flat sheets 101, which is more convenient for cleaning hair debris, thereby improving the drying performance and effectively improving the user experience.

[0073] In one embodiment, the number of tube bodies 121 of the tube group 120 is greater than 3 and not greater than 5. In the front-to-back direction, the tube bodies 121 of the last two rows of the tube group 120 are provided with the second fin group 300, and the remaining tube bodies 121 of the tube group 120 are provided with the first fin group 200. In other words, two types of fin combinations are used. When the number of tube bodies 121 of the tube group 120 is four or five, the tube bodies 121 of the last two rows of the tube group 120 are penetrated on the second fins 310, and the tube bodies 121 of the first two rows or the first three rows of the tube group 120 are penetrated on the first fins 210. In this way, the heat exchange effect of the fin heat exchanger can be enhanced, and the excessive air duct resistance caused by the use of all second fins 310, such as window sheets 102, can be effectively avoided. In addition, the first few rows of the heat exchanger using the first fins 210, such as flat sheets 101, are more convenient for cleaning hair scraps, which can improve the drying performance and effectively improve the user experience.

[0074] In one embodiment, please refer to Figure 3 and Figure 4 , the number of tube bodies 121 of the tube group 120 is greater than 5. In the front-to-back direction, the first five rows of tube bodies 121 of the tube group 120 are provided with the first fin group 200, and the remaining tube bodies 121 of the tube group 120 are all provided with the second fin group 300. In other words, the tube bodies 121 after the fifth row of the tube group 120 are all penetrated on the second fins 310. Since the heat exchange efficiency of the remaining rows of tube bodies 121 after the fifth row is very low, for example, the heat exchange efficiency is likely to be less than 10%, therefore, the tube bodies 121 after the fifth row of the tube group 120 are all provided with the second fin group 300 to improve the heat exchange efficiency.

[0075] In one embodiment, the fin heat exchanger includes a transition fin group, the transition fin group includes a plurality of transition fins arranged at intervals along a first direction, at least one tube body 121 of the tube group 120 is provided with a transition fin group, the heat exchange efficiency of the transition fin is higher than the heat exchange efficiency of the first fin 210, and the heat exchange efficiency of the transition fin is lower than the heat exchange efficiency of the second fin 310. In this embodiment, the number of tube bodies 121 of the tube group 120 is not less than 3, and the fin heat exchanger adopts a combination of three or more types of fins. In the front-to-back direction, the transition fin group is located between the second fin group 300 and the first fin group 200, that is, the transition fin group is arranged on the tube body 121 of the tube group 120 located between the first fin group 200 and the second fin group 300. In this way, the requirements of heat exchange efficiency, production cost, and convenience of cleaning dander can be further taken into account, thereby improving the user experience.

[0076] At least one tube body 121 of the tube group 120 is provided with a transition fin group, which means that one tube body 121 of the tube group 120 may be provided with a transition fin group. Alternatively, multiple tube bodies 121 of the tube group 120 may be provided with a transition fin group.

[0077] In some embodiments, the fin heat exchanger may include only two types of fins, namely, the first fin 210 and the second fin 310. In other embodiments, the fin heat exchanger may include three or more types of fins, namely, the first fin 210, the second fin 310, and the transition fin. For example, in one embodiment, the first fin 210 is a flat sheet 101, the transition fin is a corrugated sheet, and the second fin 310 is a window sheet 102.

[0078] The fin heat exchanger can be used as a condensing device or an evaporating device. The evaporating device is used to cool and dehumidify the hot and humid airflow from the clothing processing chamber to form a dry and cold airflow. The condensing device heats the dry and cold airflow into a dry and hot airflow.

[0079] Exemplarily, in some embodiments, the clothing processing device can adopt a heat pump type circulating drying method to achieve the drying function. Specifically, both ends of the air duct are connected to the clothing processing chamber, and the condensing device and the evaporating device are both arranged in the air duct. The refrigerant can circulate in the condensing device and the evaporating device. The circulating airflow is provided to the clothing processing chamber through the air duct. The refrigerant in the evaporating device and the condensing device exchanges heat with the airflow in the air duct to achieve heating and condensing the airflow. In the flow path of the airflow in the air duct, that is, from the front to the back direction, the evaporating device is located in front of the condensing device, and the airflow first flows through the evaporating device and then flows through the condensing device. The evaporating device is used to cool and dehumidify the hot and humid airflow from the clothing processing chamber to form a dry cold airflow, and the condensing device heats the dry cold airflow into a dry hot airflow and then flows back to the clothing processing chamber. The dry hot airflow flowing back to the clothing processing chamber contacts the wet clothes to form a hot and humid airflow again, completing a drying cycle. By repeatedly running the drying cycle, the circulating airflow is continuously provided to the clothing processing chamber to dry the clothes. In this embodiment, at least one of the condensing device and the evaporating device can adopt the finned heat exchanger provided in the embodiment of the present application, which can take into account both the heat exchange effect and the cost.

[0080] It should be understood that the dry and cold airflow is relative to the humid and hot airflow. The temperature of the dry and cold airflow is lower than the temperature of the humid and hot airflow, and the humidity of the dry and cold airflow is lower than that of the humid and hot airflow.

[0081] In one embodiment, there are multiple fin heat exchangers, and the multiple fin heat exchangers are arranged in the front-to-back direction. The refrigerant outlet 100b of the refrigerant tube 100 of the previous fin heat exchanger is connected to the refrigerant inlet 100a of the refrigerant tube 100 of the next fin heat exchanger. In other words, the refrigerant in the refrigerant tube 100 of the previous fin heat exchanger directly enters the refrigerant tube 100 of the next fin heat exchanger, and no throttling device is provided between the previous fin heat exchanger and the next fin heat exchanger. In this embodiment, multiple fin heat exchangers are superimposed to form a heat exchange combination, which has a heat absorption effect or a heat release effect. In other words, the heat exchange combination is an evaporation device or a condensation device, and multiple fin heat exchangers absorb the heat of the airflow together or release heat to the airflow. In this way, the heat exchange effect is further improved.

[0082] In one embodiment, the clothing processing device includes a microchannel heat exchanger arranged in the air duct, the microchannel heat exchanger is located behind the fin heat exchanger, and the refrigerant inlet of the microchannel heat exchanger is connected to the refrigerant outlet 100b of the refrigerant pipe 100 of the fin heat exchanger. In other words, the refrigerant in the refrigerant pipe 100 of the fin heat exchanger directly enters the refrigerant pipe 100 of the microchannel heat exchanger, and no throttling device is provided between the fin heat exchanger and the microchannel heat exchanger. In this embodiment, the fin heat exchanger and the microchannel heat exchanger are superimposed to form a heat exchange combination, which plays a heat absorption or heat release role. In other words, the heat exchange combination is an evaporation device or a condensation device, and the fin heat exchanger and the microchannel heat exchanger jointly absorb the heat of the airflow or release heat to the airflow. The heat exchange efficiency of the microchannel heat exchanger is higher than that of the fin heat exchanger. The microchannel heat exchanger is arranged behind the fin heat exchanger to improve the heat exchange efficiency of the rear airflow, so that the heat exchange efficiency of each area of ​​the heat exchange combination along the front and rear directions tends to be consistent. Further improve the heat exchange effect.

[0083] Exemplarily, the microchannel heat exchanger includes two liquid collecting tubes and flat tubes, the two liquid collecting tubes are arranged side by side and spaced along the length direction of the flat tubes, the flat tubes connect the two liquid collecting tubes, and the flat tubes have multiple microchannels, the multiple microchannels are spaced along the width direction of the flat tubes, and the equivalent diameter of the microchannels is between 10 μm (micrometer) and 1000 μm. One of the liquid collecting tubes has a refrigerant inlet, and the other liquid collecting tube has a refrigerant outlet. When the refrigerant passes through the microchannel, it can exchange heat with the airflow to be exchanged, so as to enhance the heat exchange effect.

[0084] In one embodiment, the clothes processing device includes a wind wheel, which is used to drive the air flow to flow between the clothes processing chamber and the air duct. Exemplarily, the wind wheel is located in the air duct. In the process of drying clothes, the wind wheel is used to drive the air flow through the clothes to flow through the evaporation device and the condensation device in sequence, and then blow to the clothes to form circulating wind. The wind wheel can speed up the air flow and improve the drying efficiency.

[0085] In one embodiment, the clothing processing device further includes a compressor and a throttling device. The compressor, the condensing device, the throttling device and the evaporating device are sequentially connected in series through a pipeline to form a heat pump system, and the refrigerant can circulate in the heat pump system. The airflow in the air duct exchanges heat with the refrigerant in the evaporating device and the condensing device to form a dry hot airflow.

[0086] The working principle of the heat pump system is as follows: the compressor sucks in low-pressure gaseous refrigerant and compresses it into high pressure before discharging; the discharged high-pressure refrigerant enters the condensing device, and the refrigerant in the condensing device transfers heat to the airflow to condense into high-pressure liquid; the high-pressure liquid refrigerant flows through the throttling device to throttle and reduce pressure, and then becomes a low-pressure and low-temperature gas-liquid two-phase mixture and enters the evaporating device; the refrigerant in the evaporating device absorbs the heat of the airflow and becomes a low-pressure gas; the low-pressure gaseous refrigerant is sucked in by the compressor again; this cycle is repeated to achieve heat exchange. In other words, the evaporating device is used to cool and dehumidify the humid and hot airflow from the clothing processing chamber to form a dry and cold airflow, and the condensing device heats the dry and cold airflow into a dry and hot airflow and then flows back into the clothing processing chamber. The dry and hot airflow flowing back to the clothing processing chamber contacts the wet clothes and forms a humid and hot airflow again, completing a drying cycle. By repeatedly running the drying cycle, a circulating airflow is continuously provided to the clothing processing chamber to dry the clothes.

[0087] It can be understood that, when a plurality of fin heat exchangers are stacked to form a heat exchange combination or a fin heat exchanger and a microchannel heat exchanger are stacked to form a heat exchange combination; if the heat exchange combination is used as an evaporation device, the throttling device is located between the heat exchange combination and the condensation device. If the heat exchange combination is used as a condensation device, the throttling device is located between the heat exchange combination and the evaporation device.

[0088] It should be noted that any one of the condensing device and the evaporating device may adopt a heat exchange combination. Both the condensing device and the evaporating device may adopt a heat exchange combination.
