However, obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Typically, the components of the embodiments of the present application described and illustrated in the accompanying drawings herein can be arranged and designed in various different forms. Therefore, the detailed description of the embodiments of the present application provided below in the accompanying drawings does not limit the scope of protection of the present application, but is intended to show only specific embodiments of the present application, and features included in different embodiments can be combined with each other. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative work (including new embodiments formed by combining features included in different embodiments with each other) are all included in the scope of protection of the present application.

[0022] It should be noted that in the following accompanying drawings, like symbols and letters indicate like items, so once an item is defined in one accompanying drawing, further definition and explanation are unnecessary in subsequent accompanying drawings. At the same time, in the description of this application, terms such as "first," "second," etc. are used only to distinguish the description, and are not to be understood as indicating or implying relative importance.

[0023] The present application provides a clothing treatment device. The clothing treatment device is used for washing, rinsing, ironing, drying, and other treatments of clothing. The clothing treatment device includes, but is not limited to, a washing machine, a dryer, an integrated washer-dryer, and the like. FIGS. 1 to 3 respectively show a three-dimensional view, a rear view, and a top view of an integrated washer-dryer 1000 according to an embodiment of the present disclosure. FIGS. 4 and 5 respectively show a top view and a three-dimensional view of a drying device 2000 in FIGS. 2 and 3.

[0024] In this specification, the clothing treatment device of the embodiment of the present disclosure will be described using the side-opening all-in-one washer-dryer washing machine 1000 shown in Figures 1 to 3 as an example. The clothing treatment device of the embodiment of the present disclosure can be applied to any type of clothing treatment device, including, but not limited to, a side-opening drum washing machine, a top-opening drum washing machine, a wave washing machine, an agitator washing machine, a small (mini) washing machine, and the like.

[0025] As shown in FIGS. 1 to 3, the combined washer-dryer washing machine 1000 includes a garment storage device 1100 for storing garments to be processed ("processing" here may refer to either washing or drying). The garment storage device 1100 may be a storage cylinder, a storage basket, or any other device capable of storing garments. For example, the garment storage device 1100 may be configured as a drum. The drum consists of an inner cylinder and an outer cylinder. The inner cylinder is used to hold the garments to be processed and rotates under the action of a drive mechanism, while the outer cylinder is fixed relative to the main body by a suspension means. The inner cylinder is provided with water and air permeable holes. The outer cylinder is impermeable to both water and air and has a first air outlet. The diameter of the inner cylinder is smaller than that of the outer cylinder. A door main body 1110 is opened at a position corresponding to the garment storage device 1100 on a housing 1200 of the combined washer-dryer washing machine 1000. The door main body 1110 is pivotally connected to the housing 1200. The opening and closing of the door body 1110 may be controlled manually by a user or with the aid of an electronic controller.

[0026] As shown in FIGS. 1 to 3, the combined washer-dryer washing machine 1000 includes a drying device 2000 for drying clothes in a clothing storage device 1100. The drying device 2000 is located above the clothing storage device 1100. The relative positions of the clothing storage device 1100 and the drying device 2000 are not fixed, and they may be located one above the other, or one behind the other. For example, the drying device 2000 may be located above the clothing storage device 1100 (FIG. 2), or behind the clothing storage device 1100, or below the clothing storage device 1100, or to the side of the clothing storage device 1100 (not shown).

[0027] As shown in FIGS. 4 and 5, in the embodiment of the present disclosure, the drying device 2000 includes a moisture absorption passage, a regeneration passage, a circulation fan 2100, a moisture absorption and dehumidification member 2200, a moisture absorption and dehumidification rotating disk drive unit 2300, and a regeneration fan 2400.

[0028] As shown in FIG. 2, the first air inlet 2901 of the moisture absorption passage is connected to the air outlet duct 1300 of the clothing storage device 1100. The first air outlet 2902 of the moisture absorption passage is connected to the air inlet duct of the clothing storage device 1100. For example, as shown in FIG. 5, the first air outlet 2902 is connected to the air inlet duct (not shown in FIG. 5) of the clothing storage device 1100 via a connecting member 1400. The circulation fan 2100 is located in the moisture absorption passage and is used to form a circulation airflow within the clothing storage device 1100 and the moisture absorption passage. The regeneration fan 2400 is located in the regeneration passage and is used to form a regeneration airflow / dehumidification airflow within the regeneration passage.

[0029] 2 and 5, the clothing storage apparatus 1100 has a first airflow inlet and a first airflow outlet. The first airflow inlet is a connection between the air inlet duct and the clothing storage apparatus 1100. Alternatively, the first airflow inlet on the clothing storage apparatus 1100 is in communication with the drying apparatus 2000 via the air inlet duct. The first airflow outlet is a connection between the air outlet duct 1300 and the clothing storage apparatus 1100. Alternatively, the first airflow outlet on the clothing storage apparatus 1100 is in communication with the drying apparatus 2000 via the air outlet duct 1300.

[0030] A portion of moisture absorbing and dehumidifying member 2200 is located on the moisture absorption passage, and another portion is located on the regeneration passage, so that the circulating airflow in the moisture absorption passage and the dehumidifying airflow in the regeneration passage all flow through moisture absorbing and dehumidifying member 2200. Moisture absorbing and dehumidifying rotary disk driver 2300, for example, a drive motor, is used to move (e.g., rotate) moisture absorbing and dehumidifying member 2200 relative to the moisture absorption passage and the regeneration passage. During the rotation of moisture absorbing and dehumidifying member 2200, moisture in the circulating airflow is absorbed and then discharged via the dehumidifying airflow.

[0031] According to some embodiments, moisture absorbing and dehumidifying member 2200 may include moisture absorbing and dehumidifying rotating disk 2201. A moisture absorbent for absorbing moisture is disposed on moisture absorbing and dehumidifying rotating disk 2201. The moisture absorbent may be, for example, zeolite (molecular sieve), alkali metal silica aluminate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, or the like.

[0032] The moisture absorbing and dehumidifying rotating disk drive unit 2300 is used to rotate the moisture absorbing and dehumidifying rotating disk 2201 relative to the moisture absorption path and the regeneration path. A circulating airflow and a dehumidifying flow flow simultaneously through the moisture absorbing and dehumidifying rotating disk 2201. Here, the area of ​​the moisture absorbing and dehumidifying rotating disk 2201 that is circulated by the airflow is the moisture absorption area, and the area that is circulated by the dehumidifying flow is the regeneration area.

[0033] According to some embodiments, as shown in Figures 4 and 5, the drying device 2000 further includes a heating module 2500 and a condensing module 2600 provided in the regeneration passage. The heating module 2500 covers the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying rotating disk 2201) and is used to heat the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying rotating disk 2201) and desorb moisture absorbed by the moisture absorbing and dehumidifying member 2200 (moisture absorbing and dehumidifying rotating disk 2201). The condensing module 2600 is used to condense the dehumidified stream flowing out from the regeneration area of ​​the moisture absorbing and dehumidifying member 2200 to dry the dehumidified stream.

[0034] According to some embodiments, a rotating disk detection device is provided at the position of the moisture absorbing and dehumidifying rotating disk 2201, which monitors the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 and sends the information to the control device of the clothing treatment device, thereby maintaining continuous rotation of the moisture absorbing and dehumidifying rotating disk 2201 during the drying process and preventing the heating module 2500 from continuously heating a certain area and burning the moisture absorbing and dehumidifying rotating disk 2201. The control device of the clothing treatment device appropriately adjusts the heating power of the heating module 2500, the circulating power of the circulating fan 2100, the regenerating power of the regenerating fan 2400, etc. through feedback of the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201.

[0035] According to some embodiments, drying apparatus 2000 further includes an upper housing and a lower housing. The upper and lower housings surround and secure each component of drying apparatus 2000 so that drying apparatus 2000 forms an integrated module. According to some embodiments, drying apparatus 2000 further includes a housing. The housing includes a first housing (lower housing 2700) and a second housing (upper housing 2820) that house moisture absorbing and dehumidifying rotating disk 2201. Two partition ribs, first separating members 2725-1 and 2725-2 shown in FIG. 16, are provided on the first housing, and two partition ribs, second separating members 2822-1 and 2822-2 shown in FIG. 17, are provided on the second housing. A short shaft 2721 and a storage section for attaching the short shaft 2721 are provided at the center of the first housing (lower housing 2700), and one partition rib 2725-1 of the first housing is provided to extend from the inner peripheral wall of the housing to the housing storage section. Another partition rib 2725-2 of the first housing (lower housing 2700) is provided to extend from another position on the inner peripheral wall of the housing to the housing storage section. At least two partition ribs do not intersect with the short shaft 2721, thereby dividing the internal space formed by docking the first and second housings into two spaces, i.e., a first space and a second space, a moisture absorption space and a regeneration space, or a moisture absorption region and a regeneration region. According to some embodiments, the storage section is annular, and at least two partition ribs are provided tangentially to the outer periphery of the annular storage section.

[0036] According to some embodiments, the upper and lower housings of drying apparatus 2000 may each correspond to separate housings of a single component of drying apparatus 2000, or may correspond to an integrated housing of multiple components of drying apparatus 2000. For example, in the embodiments shown in FIGS. 4 and 5, lower housing 2700 of drying apparatus 2000 is an integrated housing. FIG. 6 further illustrates a structural diagram of the integrated lower housing 2700. As shown in FIG. 6, lower housing 2700 is provided with a mounting portion 2710 for mounting circulation fan 2100, a mounting portion 2720 (first mounting portion) for mounting moisture absorbing / dehumidifying member 2200, a mounting portion 2730 for mounting regeneration fan 2400, and a mounting portion 2740 for mounting condensation module 2600. The upper housing of the drying device 2000 is a separate housing, and includes an upper housing 2810 for mounting the circulation fan 2100, an upper housing 2820 for mounting the moisture absorbing and dehumidifying member 2200, an upper housing 2830 for mounting the condensation module 2600, and the like.

[0037] According to some embodiments, as shown in Figures 3 to 5, lower housing 2700 of drying device 2000 is provided with a plurality of fourth mounting portions 2701, and upper housing 2820 is provided with fifth mounting portion 2801. Fourth mounting portion 2701 and fifth mounting portion 2801 are fastened to housing 1200 of integrated washer-dryer washing machine 1000 with a wrap fastener, thereby achieving attachment and fixation of the entire drying device 2000. In this embodiment, there is no direct rigid connection between drying device 2000 and clothing accommodation device 1100, which prevents vibrations from clothing accommodation device 1100 from being transmitted to drying device 2000 (especially moisture absorbing and dehumidifying member 2200) during operation, thereby improving the stability and reliability of drying device 2000.

[0038] According to some embodiments, as shown in FIGS. 2 and 5, the first air inlet 2901 of the moisture absorption passage of the drying device 2000 communicates with the air outlet duct 1300 of the clothing accommodation device 1100 via a flexible tube (e.g., a corrugated hose) 2903. According to some embodiments, the air outlet duct 1300 may be provided with a filter (e.g., a filter mesh) for filtering out dust and clothing lint. Furthermore, the connecting member 1400 may communicate with the air inlet duct of the clothing accommodation device 1100 via a flexible tube (not shown in FIGS. 2 and 5). This prevents vibrations from the clothing accommodation device 1100 from being transmitted to the drying device 2000 (especially the moisture absorption and dehumidification member 2200), thereby improving the stability and reliability of the drying device 2000.

[0039] 4 and 5, each component of drying device 2000 (including circulation fan 2100, moisture absorption and dehumidification member 2200, moisture absorption and dehumidification rotating disk drive unit 2300, regeneration fan 2400, heating module 2500, condensation module 2600, etc.) is horizontally arranged, substantially parallel to the rotation axes of the rotating components (circulation fan 2100, moisture absorption and dehumidification member 2200, moisture absorption and dehumidification rotating disk drive unit 2300, regeneration fan 2400), and substantially perpendicular to the rotation axes of upper housing of combined washer-dryer washing machine 1000 and clothing storage device 1100. According to this embodiment, the height of combined washer-dryer washing machine 1000 can be minimized, thereby saving space.

[0040] It should be understood that because the clothing storage device 1100 is typically a cylindrical structure with its axis of rotation parallel to the ground, there is more available space above (as opposed to directly above) the sides of the clothing storage device 1100. According to some embodiments, some components of the drying device 2000 can be located above the sides of the clothing storage device 1100 and in the space within the housing 1200, thereby fully utilizing the internal space of the combined washer-dryer-and-dryer 1000 and making the structure of the combined washer-dryer-and-dryer 1000 more compact and reducing its volume. For example, in the embodiment shown in FIGS. 3-5 , components such as the circulation fan 2100, the moisture absorption and dehumidification rotary disk drive unit 2300, the regeneration fan 2400, and the condensation module 2600 are all located above the sides of the clothing storage device 1100. In this embodiment, the overall height of the combined washer-and-dryer 1000 depends on the diameter of the clothing storage device 1100 and the thickness of the components directly above the clothing storage device 1100 (i.e., the moisture absorption and dehumidification member 220).

[0041] In some embodiments, the rotation axes of the two largest diameter rotating members of the drying device 2000 are located on either side of the rotation axis of the clothing storage device 1100, and both are perpendicular to, rather than flush with, the rotation axis of the clothing storage device 1100. This allows for more efficient use of the internal space of the combined washer-dryer 1000, making its structure more compact and reducing its volume. For example, in the embodiment shown in Figures 3 to 5, the two largest diameter rotating members are the moisture absorbing and dehumidifying member 2200 and the circulation fan 2100, and the rotation axes of the moisture absorbing and dehumidifying member 2200 and the circulation fan 2100 are located on the left and right sides of the clothing storage device 1100 (when viewed from the front of the combined washer-dryer 1000), respectively, and are perpendicular to, rather than flush with, the rotation axis of the clothing storage device 1100.

[0042] Currently, the related art does not consider the coordination of two parameters, namely, the area ratio between the moisture absorption space and the dehumidification space of the moisture absorption and dehumidification rotating disk 2201 and the power ratio between the circulation fan 2100 and the regeneration fan 2400. However, the coordination of these two parameters obviously contributes to improving drying efficiency. Assuming that the moisture absorption and dehumidification rotating disk 2201 has a reasonable volume, as long as the area ratio between the moisture absorption space and the dehumidification space is within a preferred range, both the moisture absorption capacity and the dehumidification capacity can be effectively improved.

[0043] According to some embodiments, the circulation fan 2100 operates at a first power to generate a circulation airflow passing between the clothing storage device 1100 and the moisture absorption space of the drying device 2000. The regeneration fan 2400 operates at a second power to generate a regeneration airflow passing through the dehumidification space. In one embodiment, the ratio of the first power to the second power is 2:1 to 4:1. For example, the ratio of the first power to the second power may be 2:1, 2.4:1, 2.8:1, 3:1, 3.2:1, 3.5:1, 3.8:1, 4:1, etc. More specifically, the first power of the circulation fan 2100 may be set within a range of 30W to 90W. The second power of the regeneration fan 2400 may be set within a range of 10W to 30W.

[0044] The projected area of ​​the moisture absorption space in at least one plane perpendicular to the rotation axis is the effective area for achieving the defined moisture absorption function when the moisture absorbing and dehumidifying rotary disk 2201 rotates to the moisture absorption region. The projected area of ​​the dehumidifying space in at least one plane perpendicular to the rotation axis is the effective area for achieving the defined dehumidification function when the moisture absorbing and dehumidifying rotary disk 2201 rotates to the regeneration region. The ratio of the projected areas of the moisture absorption space and the dehumidifying space in at least one plane perpendicular to the rotation axis is within the range of 2:1 to 4:1, such as 2:1, 2.4:1, 2.8:1, 3:1, 3.2:1, 3.6:1, or 4:1.

[0045] The difference between the area ratio of the projected moisture absorption space to the dehumidifying space in at least one plane perpendicular to the rotation axis and the power ratio between the first power and the second power is within a range of ±2, or the difference between the area ratio of the moisture absorption space to the dehumidifying space and the power ratio between the first power and the second power is very small, i.e., the area ratio and power ratio are equivalent. For example, if the projected area ratio of the moisture absorption space to the dehumidifying space in at least one plane perpendicular to the rotation axis is 2:1 and the power ratio between the first power and the second power is 3:1, the difference between the area ratio and the power ratio is -1. For example, if the projected area ratio of the moisture absorption space to the dehumidifying space in at least one plane perpendicular to the rotation axis is 3:1 and the power ratio between the first power and the second power is 2:1, the difference between the area ratio and the power ratio is 1. For example, if the projected area ratio of the moisture absorption space to the dehumidification space in at least one plane perpendicular to the rotation axis is 3:1 and the power ratio between the first power and the second power is 3:1, the difference between the area ratio and the power ratio is 0. If the projected area ratio of the moisture absorption space to the dehumidification space in at least one plane perpendicular to the rotation axis is 3:1, the area of ​​the moisture absorption space will occupy approximately 75% of the entire area of ​​the moisture absorption and dehumidification rotating disk 2201, and the area of ​​the dehumidification space will occupy approximately 25% of the entire area of ​​the moisture absorption and dehumidification rotating disk 2201. If the power ratio between the first power and the second power is 3:1, the power of the circulation fan 2100 can be set to approximately 60 W and the power of the regeneration fan 2400 can be set to approximately 20 W.

[0046] In this embodiment, the difference between the area ratio and power ratio is within ±2, which effectively controls the airflow entering the moisture absorption space and the dehumidification space, thereby effectively improving moisture absorption and dehumidification efficiency. The circulation fan 2100 and the regeneration fan 2400 operate at an appropriate power ratio to provide appropriate amounts of circulation airflow and regeneration airflow for moisture absorption and dehumidification. Reasonable coordination between the structure of the moisture absorption / dehumidification rotating disk 2201 and the power of the circulation fan 2100 and the power of the regeneration fan 2400 can maximize the moisture absorption and dehumidification efficiency of the dryer 2000.

[0047] In one embodiment, the moisture absorbing / dehumidifying rotating disk driver 2300 drives the moisture absorbing / dehumidifying rotating disk 2201 at a first rotation speed. A specific first rotation speed may be 2 to 10 rpm (turns per minute). A specific first rotation speed may be set to 2 rpm, 3 rpm, 4 rpm, 5 rpm, 6 rpm, 7 rpm, 7.5 rpm, 9 rpm, 10 rpm, etc.

[0048] In this embodiment, when the area ratio of moisture absorbing and dehumidifying rotating disk 2201 and the power ratio of the two fans are within appropriate ranges, moisture absorbing and dehumidifying rotating disk driver 2300 drives moisture absorbing and dehumidifying rotating disk 2201 to rotate at a first rotation speed, thereby fully exerting the moisture absorption effect of the moisture absorption space and the dehumidification effect of the dehumidification space, thereby improving drying efficiency. Specifically, it can be seen that circulation fan 2100 operates at a first power to transport the airflow in clothing storage device 1100 from air outlet duct 1300 to the moisture absorption space as a circulating airflow. Moisture absorbing and dehumidifying rotating disk 2201 rotating at the first rotation speed in the moisture absorption space absorbs water vapor in the circulating airflow during rotation. The circulating airflow passes through the humidifying and dehumidifying rotating disk 2201 from one side to the other side in the thickness direction of the humidifying and dehumidifying rotating disk 2201, absorbing the water vapor in the circulating airflow. The regenerating fan 2400, operating with the second power, transports the regenerated airflow / dehumidified airflow to the regenerating region. The humidifying and dehumidifying rotating disk 2201, rotating at the first rotational speed into the dehumidifying space, encounters the regenerated airflow / dehumidified airflow, discharging the water vapor in the humidifying and dehumidifying rotating disk 2201, allowing the humidifying and dehumidifying rotating disk 2201, which has rotated out of the dehumidifying space, to regain its moisture-absorbing ability. When the humidifying and dehumidifying rotating disk 2201 in the dehumidifying space encounters the regenerating airflow / dehumidifying airflow, the regenerating airflow / dehumidifying airflow also travels in the thickness direction of the humidifying and dehumidifying rotating disk 2201 from one side to the other side, passing through the humidifying and dehumidifying rotating disk 2201, thereby achieving the purpose of discharging water vapor from the humidifying and dehumidifying rotating disk 2201. Therefore, the area ratio within the humidifying and dehumidifying rotating disk 2201, the power ratio between the two fans, and the first rotation speed of the humidifying and dehumidifying rotating disk 2201 are coordinated to fully exert the moisture absorption effect of the humidifying and dehumidifying rotating disk 2201 in the absorbing space and the dehumidifying effect of the humidifying and dehumidifying rotating disk 2201 in the dehumidifying space, thereby further improving the drying efficiency of the drying device 2000.

[0049] In one embodiment, the heating module 2100 operates between a first heating power and a second heating power. The heating module 2100 operates between the first heating power and the second heating power according to a waveform such as a sine wave, a square wave, a sawtooth wave, etc. The heating module 2100 may also operate between the first heating power and the second heating power according to other irregular waveforms. The specific operating mode of the heating module 2100 can be adjusted according to actual conditions, for example, it may operate in different modes at different heating stages of the drying process.

[0050] The first heating power may be set to 400 W to 800 W, and the second heating power may be set to 1200 W to 1600 W. In one embodiment, the first heating power is 400 W, and the second heating power is 1600 W. In one embodiment, the first heating power is 550 W, and the second heating power is 1450 W. In one embodiment, the heating power of the heating module 2100 may vary in the form of a square wave in the range of 600 W to 1400 W. In another embodiment, the heating module 2100 may operate according to the following operating cycle T, for example, operating at a second heating power of 1300 W for 3 / 4 T, then operating at a first heating power of 550 W for 1 / 4 T, and then repeatedly operating at the operating cycle T until drying is completed. In another embodiment, the heater may be operated alternately and repeatedly according to operation cycles T1 and T2, for example, by operating at a second heating power of 1400 W for 1 / 2 T1, then operating at a first heating power of 600 W for 1 / 2 T1, then operating at a second heating power of 1250 W for 1 / 2 T2, and then operating at a first heating power of 750 W for 1 / 2 T2, and so on until drying is completed.

[0051] In this embodiment, the heating module 2100 operates according to an appropriate heating law, which can avoid uneven heating of the moisture absorbing and dehumidifying rotating disk 2201, shorten the heating time or drying time, improve the moisture absorption effect of the moisture absorbing space and the dehumidification effect of the dehumidifying space, and further improve the drying efficiency.

[0052] In one embodiment, the condensation module 2600 is installed at the rear / downstream end of the dehumidification space and communicates with the regeneration airflow outlet of the regeneration fan 2400. It is used to condense the high-temperature, high-humidity regeneration airflow output from the regeneration airflow outlet to form a low-temperature, dry airflow. The condensation module 2600 is a water-cooled condenser that condenses the gas discharged from the dehumidification space by water cooling. The water flow rate is 0.2 to 0.4 L / min. In one embodiment, the water flow rate is 0.35 L / min.

[0053] This embodiment provides a condensation method for the condensation module 2600, which condenses the gas discharged from the dehumidification space, condensing some of the water vapor into liquid water, which is then discharged, thereby reducing the moisture content in the airflow and improving the dewatering efficiency of the drying device 2000.

[0054] The moisture absorbing and dehumidifying rotating disk driver 2300 drives the moisture absorbing and dehumidifying rotating disk 2201 to rotate. When the moisture absorbing and dehumidifying rotating disk 2201 rotates to the moisture absorbing region, it absorbs moisture from the airflow. After absorbing moisture, the moisture absorbing and dehumidifying rotating disk 2201 continues to rotate to the playback region. The moisture absorbing and dehumidifying rotating disk 2201 dehumidifies the airflow in the playback region. After dehumidification, the moisture absorbing and dehumidifying rotating disk 2201 regains its moisture absorbing function and continues to rotate to the moisture absorbing region and absorb moisture, repeating this process. Therefore, different thicknesses and diameters of the moisture absorbing and dehumidifying rotating disk 2201 affect the moisture absorbing and dehumidifying effect of the airflow. Furthermore, the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 also affects the moisture absorbing and dehumidifying effect of the airflow.

[0055] In one set of embodiments, the ratio of thickness to diameter of the moisture absorbing and dehumidifying rotating disk 2201 is 1:20 to 1:5. The rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is 2 to 10 rpm. In other different embodiments, the ratio of thickness to diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 1:15, 1:13, 1:12, 1:10, or other values. In other different embodiments, the first rotation speed may be set to 3 rpm, 4 rpm, 5 rpm, 6 rpm, 7 rpm, 8 rpm, 9 rpm, 10 rpm, or other non-integer numbers (e.g., 3.5 rpm, 4.5 rpm, 5.5 rpm, 6.5 rpm, etc.).

[0056] In one embodiment, the moisture absorbing and dehumidifying rotating disk 2201 may be cylindrical. The thickness of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 10 mm to 100 mm. The diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 40 mm to 500 mm. For example, in one embodiment, the thickness of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 25 mm and the diameter may be set to 320 mm. In one embodiment, the thickness of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 30 mm and the diameter may be set to 200 mm. In another embodiment, the thickness of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 35 mm and the diameter may be set to 300 mm. In another embodiment, the thickness of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 40 mm and the diameter may be set to 350 mm.

[0057] In one embodiment, when the thickness of the moisture absorbing and dehumidifying rotating disk 2201 is set to 35 mm, the diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 175 mm to 750 mm.

[0058] In one embodiment, when the thickness of the moisture absorbing and dehumidifying rotating disk 2201 is set to 42 mm, the diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 210 mm to 840 mm.

[0059] In one embodiment, when the thickness of the moisture absorbing and dehumidifying rotating disk 2201 is set to 25 mm, the diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to 125 mm to 500 mm. The thickness and diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be other combinations.

[0060] In this embodiment, the appropriate thickness-to-diameter ratio and the appropriate rotation speed of the moisture-absorbing and dehumidifying rotating disk 2201 are set, so that the structure and movement state of the moisture-absorbing and dehumidifying rotating disk 2201 can be clarified and a good drying effect can be obtained.

[0061] In one embodiment, the thickness-to-diameter ratio of the moisture absorbing and dehumidifying rotating disk 2201 is set to 1:15 to 1:10, the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is set to 4 to 6 rpm, and the area ratio of the moisture absorbing space to the dehumidifying space is further set to 2:1 to 4:1. For example, the area ratio of the moisture absorbing space to the dehumidifying space is 2:1, 5:2, 7:2, or 4:1. The drying efficiency can be further improved by combining the three parameter values ​​of the thickness-to-diameter ratio of the moisture absorbing and dehumidifying rotating disk 2201, the rotation speed, and the area ratio of the moisture absorbing space to the dehumidifying space.

[0062] In one embodiment, the ratio of the diameter of the moisture absorbing and dehumidifying rotating disk 2201 to the diameter of the inner cylinder is 1:2 to 3:4. In other embodiments, the ratio of the diameter of the moisture absorbing and dehumidifying rotating disk 2201 to the diameter of the inner cylinder may be set to 2:4, 2.2:4, 2.5:4, 2.6:4, 2.8:4, or 3:4. The diameter of the moisture absorbing and dehumidifying rotating disk 2201 may be set to a range of 40 mm to 500 mm. The diameter of the inner cylinder may be set to a range of 400 to 800 mm, and the specific diameter of the inner cylinder can be adjusted depending on the clothing capacity / weight of the clothing. For example, the diameter of the moisture absorbing and dehumidifying rotating disk is 300 mm and the diameter of the inner cylinder is 480 mm. For example, the diameter of the moisture absorbing and dehumidifying rotating disk is 320 mm and the diameter of the inner cylinder is 580 mm. For example, the diameter of the moisture absorbing and dehumidifying rotating disk is 350 mm and the diameter of the inner cylinder is 470 mm. The diameter of the moisture absorbing / dehumidifying rotary disk is 320 mm, and the diameter of the inner cylinder is 580 mm.

[0063] In this embodiment, on the one hand, the overall machine structure of the clothing treatment device needs to be kept to an appropriate volume, and the drying device 2000 needs to be provided with other structural members in addition to the moisture absorbing and dehumidifying rotating disk 2201, so the diameter of the moisture absorbing and dehumidifying rotating disk 2201 needs to be smaller than the diameter of the inner cylinder. On the other hand, in order to improve the drying efficiency of the entire machine, the area of ​​the moisture absorbing and dehumidifying rotating disk 2201 needs to be increased to improve the moisture absorption and dehumidification capabilities of the moisture absorbing and dehumidifying rotating disk 2201, so the moisture absorbing and dehumidifying rotating disk 2201 needs to be set as large as possible. In this embodiment, the ratio of the diameter of the moisture absorbing and dehumidifying rotating disk 2201 to the diameter of the inner cylinder is set to 1:2 to 3:4, which makes it possible to achieve both the size of the overall machine structure and the drying efficiency of the entire machine (improving drying efficiency by increasing moisture absorption and dehumidification capabilities).

[0064] In one embodiment, after determining the diameter of the inner cylinder, the diameter of the outer cylinder is then selected. For example, the inner cylinder diameter is set to 600 mm and the outer cylinder diameter is set to 800 mm. For example, the inner cylinder diameter is set to 510 mm and the outer cylinder diameter is set to 680 mm. Since the drying device 2000 is connected to the clothing storage device 1100 via the air outlet duct 1300, the diameters of the inner cylinder, the outer cylinder, and the diameter of the moisture-absorbing and dehumidifying rotating disk 2201 are set so that the gas in the inner cylinder (clothing storage device 1100) can be smoothly guided to the moisture-absorbing and dehumidifying rotating disk 2201 (the drying device 2000). Of course, cooperation of other structural components is required to smoothly guide the gas in the inner cylinder to the moisture-absorbing and dehumidifying rotating disk 2201. For example, the air outlet duct 1300 must have an appropriate inner diameter (to achieve a certain amount of gas delivery per unit time), the moisture-absorbing and dehumidifying rotating disk 2201 must have good moisture-absorbing and dehumidifying properties, and the circulation fan 2100 must operate at an appropriate power. For example, when the diameter of the inner cylinder is set to 510 mm, the diameter of the moisture absorbing / dehumidifying rotating disk 2201 is set to 320 mm.

[0065] In this embodiment, the diameter of the inner cylinder, the diameter of the outer cylinder, and the diameter of the moisture-absorbing and dehumidifying rotating disk 2201 are reasonably set taking into consideration conditions such as the volume / weight of the clothes in the inner cylinder, the amount of gas discharged from the air outlet duct 1300, and the moisture-absorbing and dehumidifying effect of the moisture-absorbing and dehumidifying rotating disk 2201. Through effective coordination of multiple parameters, the gas in the inner cylinder can be smoothly guided to the moisture-absorbing and dehumidifying rotating disk 2201, effectively improving the moisture-absorbing and dehumidifying efficiency.

[0066] In one embodiment, the first power and the second power can be adjusted according to the ratio of the thickness to the diameter and the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201. For example, if the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is accelerated, the first power and / or the second power can be appropriately increased. In one embodiment, the ratio of the first power to the second power is 2:1 to 4:1. For example, the moisture absorbing and dehumidifying rotating disk 2201 has a thickness of 25 mm and a diameter of 320 mm. The rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is 5 rpm. The first power is set to 40 W and the second power is set to 10 W. For example, the moisture absorbing and dehumidifying rotating disk 2201 has a thickness of 25 mm and a diameter of 320 mm. The rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is 6 rpm. The first power is set to 50 W and the second power is set to 12 W. For example, the moisture absorbing and dehumidifying rotating disk 2201 has a thickness of 25 mm and a diameter of 320 mm. The rotation speed of the moisture absorbing / dehumidifying rotating disk 2201 is 7 rpm. The first power is set to 60 W, and the second power is set to 18 W.

[0067] In this embodiment, the ratio of thickness to diameter of the moisture absorbing and dehumidifying rotating disk 2201, the rotation speed, and the magnitude of the first power and the second power can be adjusted according to the actual operating conditions of the clothing treatment device, and their cooperative relationship is not uniquely determined.

[0068] In one embodiment, the thickness-to-diameter ratio of the moisture absorbing and dehumidifying rotating disk 2201 is set to 1:20 to 1:5, the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is set to 2 to 10 rpm, and the condensation module 2600 is further configured. For example, the thickness-to-diameter ratio of the moisture absorbing and dehumidifying rotating disk 2201 is set to 1:15, the rotation speed of the moisture absorbing and dehumidifying rotating disk 2201 is set to 7 rpm, and the condensed water flow rate is set to 0.4 L / min. By rationally adjusting the parameter settings of the condensation module 2600 under different thickness-to-diameter ratios and rotation speeds, it is possible to achieve an orderly conversion from high-temperature, high-humidity airflow to low-temperature, dry airflow, improving drying efficiency.

[0069] Currently, related art only considers the direct working temperature of the drying device 2000 during the heating and drying process, and does not consider the change relationship between the temperature inside the clothing storage device 1100 or near the first air flow outlet and the temperature near the first air flow inlet. The applicant has found that drying efficiency can be improved when the temperature inside the clothing storage device 1100 or near the first air flow outlet and the temperature near the first air flow inlet satisfy a certain relationship.

[0070] In one set of embodiments, the garment treatment device further comprises a first temperature detecting device (not shown) and a second temperature detecting device (not shown). The first temperature detecting device is located near the first airflow inlet and is used to detect the temperature of the airflow entering the garment containment device 1100. The second temperature detecting device is located within the garment containment device 1100 or near the first airflow outlet and is used to detect the temperature of the airflow entering the garment containment device 1100 or the temperature of the airflow exiting the garment containment device 1100.

[0071] In at least one stage of the operation of the clothing treatment device (for example, the heating and drying stage during the drying process), the difference between the first detected temperature detected by the first detected temperature detecting device and the second detected temperature detected by the second detected temperature detecting device is 18 to 30°C. The first detected temperature is understood to be the temperature value at an arbitrary point in the temperature field of the cross section of the first airflow inlet. The second detected temperature is understood to be the temperature value at an arbitrary point in the temperature field of the cross section of the first airflow outlet, or the temperature value at an arbitrary point within the clothing storage device 1100.

[0072] In this embodiment, the clothing storage device includes an air outlet duct 1300 that connects the clothing storage device 1100 and the drying device 2000. The air outlet duct 1300 is configured to guide the airflow from the clothing storage device 1100 to the drying device 2000. During at least one stage of the clothing treatment device's operation, the moist airflow in the clothing storage device 1100 continuously flows through the moisture-absorbing and dehumidifying rotating disk 2201, which absorbs moisture in the moist airflow and delivers the dried airflow to the clothing storage device 1100, thereby stabilizing the system (maintaining a substantially stable temperature change state). In this embodiment, the first and second temperature detecting devices detect the first and second detected temperatures, respectively, thereby maintaining the difference between the first and second detected temperatures between 18 and 30°C, thereby achieving stable heating and drying of the clothes in the clothing storage device 1100 and steadily improving the drying efficiency of the drying device 2000.

[0073] In one embodiment, the first detected temperature is 70 to 85°C, and the second detected temperature is 50 to 60°C. In one embodiment, the first detected temperature is 73 to 82°C, and the second detected temperature is 53 to 56°C. In one embodiment, the first detected temperature is 75°C, the second detected temperature is 53°C, and the difference between the first detected temperature and the second detected temperature is 22°C. In one embodiment, the first detected temperature is 80°C, the second detected temperature is 55°C, and the difference between the first detected temperature and the second detected temperature is 25°C. In one embodiment, the first detected temperature is 73°C, the second detected temperature is 53°C, and the difference between the first detected temperature and the second detected temperature is 20°C. In one embodiment, the first detected temperature is 70°C, the second detected temperature is 52°C, and the difference between the first detected temperature and the second detected temperature is 18°C.

[0074] In this embodiment, when the temperature difference between the first detection temperature and the second detection temperature is maintained at 18 to 30°C, by further setting the first detection temperature range and the second detection temperature range, the drying device 2000 of the clothing processing device can be operated at 85°C or below, and the clothing in the drum can be maintained in the low temperature drying range.

[0075] In one embodiment, the heating module 2100 operates at a first heating power of 650 W and a second heating power of 1450 W and is used to dehumidify the dehumidification space. The condensing module 2600 employs a water-cooled condenser with a water flow rate of 0.38 L / min.

[0076] In this embodiment, the temperature difference between the first detected temperature and the second detected temperature is maintained at 18 to 30°C by setting the power change of the heating module 2100 and the condensation coordination of the condensing module 2600. Specifically, the range or form of change of the first heating power and the second heating power may be the heating power provided in any one of the above embodiments.

[0077] 7-9 respectively show a top view, a bottom view, and an exploded view of the circulation fan 2100. As shown in FIGS. 7-15, the circulation fan 2100 includes a motor 2110, an upper housing 2810, a fan impeller 2120, and a sealing gasket 2130.

[0078] According to some embodiments, upper housing 2810 has a worm shell shape and can function as a flow path to meet fluid design requirements and provide maximum air volume and speed to the moisture absorption passage of drying device 2000. Upper housing 2810 is provided with pipe line fixing clips 2811 for fixing pipes and wire fixing clips 2812 for fixing wiring (e.g., power wires and control wires of motor 2110). Motor 2110 is fixed to upper housing 2810 with screws.

[0079] 10 shows how circulation fan 2100 and integrated lower housing 2700 of drying apparatus 2000 cooperate with each other. As shown in FIG. 10, upper housing 2810 is fixed to mounting portion 2710 with screws 2904, thereby firmly connecting circulation fan 2100 and lower housing 2700. Sealing gasket 2130 is located at the connection between upper housing 2810 and mounting portion 2710. According to some embodiments, to attach circulation fan 2100 to lower housing 2700 and improve sealing of circulation fan 2100, a countersunk groove (not shown in FIG. 10) for accommodating sealing gasket 2130 is provided on the edge of mounting portion 2710 or the edge of upper housing 2810.

[0080] According to some embodiments, the air inlet of the circulation fan 2100 may be the first air inlet 2901 of the moisture absorption passage. Accordingly, the air inlet of the circulation fan 2100 may be connected to the air outlet duct of the inner cylinder via a flexible tube 2903. According to some embodiments, as shown in FIG. 11 , the flexible tube 2903 may be connected to the air inlet of the circulation fan 2100 by connecting the flexible tube 2903 to a pressure plate 2905 with a positioning pin and fixing the pressure plate 2905 to the mounting portion 2710 of the lower housing 2700 with a screw 2906, and the other end of the flexible tube 2903 may be similarly connected to the air outlet of the air outlet duct.

[0081] Under the operation of the circulation fan 2100, a circulating airflow can be formed between the moisture absorption passage and the inner cylinder. FIG. 12 shows the flow direction of the circulating airflow in an embodiment of the present disclosure. As shown in FIG. 12, under the operation of the circulation fan 2100, the airflow in the inner cylinder passes through the air outlet duct (equipped with a filter) of the inner cylinder and the flexible tube 2903, and then enters the first air inlet 2901 of the moisture absorption passage, i.e., the air inlet (indicated by arrow A) of the circulation fan 2100. The airflow enters the lower side of the moisture absorption and dehumidification rotating disk 2201 (indicated by arrow B) from the air outlet of the circulation fan 2100, passes through the moisture absorption and dehumidification rotating disk 2201, and reaches the upper side of the moisture absorption and dehumidification rotating disk 2201 (indicated by arrow C). The airflow flows in the upper space (corresponding to the moisture absorption region / moisture absorption space) of the moisture absorption and dehumidification rotating disk 2201 (indicated by arrow D), passes through the first air outlet 2902 of the moisture absorption passage and the connecting member 1400, and enters the inner cylinder (indicated by arrow E).

[0082] 13 and 14 are respectively an exploded view and a three-dimensional view of the moisture absorbing and dehumidifying member 2200 after assembly. FIG.

[0083] 13 , moisture absorbing and dehumidifying member 2200 includes moisture absorbing and dehumidifying rotating disk 2201, an upper peripheral clamp housing 2202, a lower peripheral clamp housing 2203, and a circumferential vibration damping member 2204. Circumferential vibration damping member 2204 is provided on the outer periphery of moisture absorbing and dehumidifying rotating disk 2201 or on the inner circumferential wall of upper peripheral clamp housing 2202 and / or lower peripheral clamp housing 2203. Upper peripheral clamp housing 2202 and lower peripheral clamp housing 2203 clamp and fix moisture absorbing and dehumidifying rotating disk 2201 and circumferential vibration damping member 2204 together. Clamping can be achieved by, for example, fasteners, screws, adhesive, etc.

[0084] The circumferential vibration damping member 2204 may be made of a material such as foam, soft rubber, woolen belt, etc. The circumferential vibration damping member 2204 is attached to the outer periphery of the moisture absorbing and dehumidifying rotating disk 2201 or to the inner circumferential wall of the outer circumferential upper clamp housing 2202 and / or the outer circumferential lower clamp housing 2203, thereby forming a buffer between the outer rim of the moisture absorbing and dehumidifying rotating disk 2201 and the inner rims of the outer circumferential upper clamp housing 2202 and the outer circumferential lower clamp housing 2203, thereby protecting the moisture absorbing and dehumidifying rotating disk 2201 from being damaged by collision with the outer circumferential upper clamp housing 2202 and the outer circumferential lower clamp housing 2203 during rotation (especially when the moisture absorbing and dehumidifying rotating disk 2201 is made of a brittle material such as a molecular sieve).

[0085] 13 and 14 , a first seal ring 2205 is provided at the connection between the outer circumferential upper clamp housing 2202 and the outer circumferential lower clamp housing 2203 or on the outer periphery of the outer circumferential upper clamp housing 2202 or the outer periphery of the outer circumferential lower clamp housing 2203 alone. The first seal ring 2205 may be made of a material such as foam, soft rubber, or leather strap. The first seal ring 2205 can seal the connection between the outer circumferential upper clamp housing 2202 and the outer circumferential lower clamp housing 2203 on the one hand, and can form a rotary seal with the housing seal ring 2724 provided on the first mounting portion 2720 of the lower housing 2700 on the other hand. This allows most of the moist airflow moving upward from the inner cylinder to pass through the moisture absorbing and dehumidifying rotating disk 2201 and be absorbed, preventing leakage through the gap between the outer periphery of the moisture absorbing and dehumidifying rotating disk 2201 and the inner periphery of the lower housing 2700, thereby ensuring moisture absorption effect.

[0086] 13 and 14 , moisture absorbing and dehumidifying member 2200 further includes a central upper clamping member 2206, a central lower clamping member 2207, and a central end vibration damping member 2208. A first hole 2209 is formed in the center of moisture absorbing and dehumidifying rotating disk 2201, a second hole 2210 is formed in the center of central upper clamping member 2206, and a third hole 2211 is formed in the center of central lower clamping member 2207. Central upper clamping member 2206 and central lower clamping member 2207 pass through first hole 2209 to clamp moisture absorbing and dehumidifying rotating disk 2201. Clamping may be achieved by, for example, fasteners, screws, adhesives, etc. The first hole 2209, the second hole 2210, and the third hole 2211 are all fitted onto the central short shaft 2721 of the first mounting part 2720 of the lower housing 2700, thereby rotatably connecting the moisture absorbing and dehumidifying member 2200 to the lower housing 2700. The central end surface vibration damping member 2208 is fitted onto the central lower clamping member 2207 and is located between the central lower clamping member 2207 and the moisture absorbing and dehumidifying rotating disk 2201 to protect the moisture absorbing and dehumidifying rotating disk 2201 and prevent it from rubbing against the central lower clamping member 2207 and being damaged during rotation.

[0087] According to some embodiments, as shown in Figures 13 and 14, drive teeth are provided on the outer periphery of the outer periphery upper clamp housing 2202. The moisture absorbing and dehumidifying rotating disk drive unit 2300 may be a drive motor, and a gear is provided at the output end of the drive motor. The gear of the drive motor meshes with the drive teeth on the outer periphery upper clamp housing 2202, thereby rotating the moisture absorbing and dehumidifying member 2200. A belt groove may be provided on the outer periphery of the outer periphery upper clamp housing 2202, and the drive motor may be driven to rotate the moisture absorbing and dehumidifying member 2200 via a belt transmission.

[0088] Note that the method for driving the moisture absorbing and dehumidifying member 2200 is not limited to the peripheral drive method shown in FIG. 14 . In some other embodiments, the moisture absorbing and dehumidifying member 2200 may be driven to rotate by other methods. For example, the output end of the moisture absorbing and dehumidifying rotary disk drive unit 2300 may be connected to the upper central clamp member 2206 or the lower central clamp member 2207, and the moisture absorbing and dehumidifying member 2200 may be rotated by the driven upper central clamp member 2206 or the lower central clamp member 2207. In other words, the moisture absorbing and dehumidifying member 2200 may be driven to rotate by a central drive method. Typically, in a central drive method, the moisture absorbing and dehumidifying rotary disk drive unit 2300 must be provided vertically (above or below) the moisture absorbing and dehumidifying member 2200. In the peripheral drive method shown in FIG. 14 , the moisture absorbing and dehumidifying rotary disk drive unit 2300 is provided horizontally to the moisture absorbing and dehumidifying member 2200. Furthermore, a central drive driving method occupies more vertical space than a peripheral drive driving method, resulting in a larger height and volume of the combined washer-dryer washing machine. However, in a central drive driving method, the moisture absorbing and dehumidifying member 2200 may be directly rotated by the moisture absorbing and dehumidifying rotating disk driving unit 2300, eliminating the need to add a gear or belt to the output end of the driving mechanism to drive the moisture absorbing and dehumidifying member 2200 as in a peripheral drive method. This simplifies the structure of the moisture absorbing and dehumidifying rotating disk driving unit 2300 and reduces the torque of the central shaft. Those skilled in the art can select an appropriate driving method for rotating the moisture absorbing and dehumidifying member 2200 according to actual needs.

[0089] 13 and 14, an auxiliary rotating ring 2212 is provided on the outer periphery of the outer periphery upper clamp housing 2202. As shown in FIG. 15, a first mounting portion 2720 of the moisture absorbing and dehumidifying member 2200 is provided on the lower housing 2700, and a flexible roller 2722 is provided on the inner wall of the first mounting portion 2720. The flexible roller 2722 is provided, for example, on a mounting portion that protrudes outward from the inner wall of the first mounting portion 2720. The rotation axis of the flexible roller 2722 is parallel to the rotation axis of the moisture absorbing and dehumidifying member 2200.

[0090] During rotation of moisture absorbing and dehumidifying member 2200, auxiliary rotatable ring 2212 rollably cooperates with flexible roller 2722 to ensure stable rotation of moisture absorbing and dehumidifying member 2200 and eliminate sliding friction between moisture absorbing and dehumidifying member 2200 and the inner circumferential rim of lower housing 2700. The diameter of flexible roller 2722 is elastically variable; that is, when flexible roller 2722 is pressed radially, the distance between the pressing point and the rotation axis of flexible roller 2722 is variable. During rotation of moisture absorbing and dehumidifying member 2200, if the rotation axis of moisture absorbing and dehumidifying member 2200 is offset from minor axis 2721, auxiliary rotatable ring 2212 can press and deform flexible roller 2722 without generating sliding friction force due to pressing between auxiliary rotatable ring 2212 and flexible roller 2722. The cooperation of the auxiliary rotating ring 2212 and the flexible roller 2722 can reduce collisions between the moisture absorbing and dehumidifying member 2200 and the inner rim of the lower housing 2700 due to unstable and uneven rotation, thereby preventing damage to the moisture absorbing and dehumidifying member 2200 (especially the moisture absorbing and dehumidifying rotating disk 2201) due to collisions.

[0091] 13 and 14, an auxiliary rotating ring 2212 may be provided on the outer periphery of the outer peripheral upper clamp housing 2202, or an auxiliary rotating ring 2212 may be provided on the outer periphery of the outer peripheral lower clamp housing 2203. Furthermore, the number of flexible rollers 2722 is not limited in the embodiments of the present disclosure. Those skilled in the art will recognize that five flexible rollers 2722 may be provided as shown in FIG. 15, or a greater or lesser number of flexible rollers 2722 may be provided.

[0092] 15 , a rigid roller 2723 is provided on the bottom surface of the first mounting portion 2720. The rigid roller 2723 may be provided, for example, on the edge of the bottom surface of the first mounting portion 2720. The rigid roller 2723 has a fixed diameter. The rotation axis of the rigid roller 2723 is perpendicular to the rotation axis of the moisture absorbing and dehumidifying member 2200. During the rotation of the moisture absorbing and dehumidifying member 2200, the rigid roller 2723 rollably cooperates with the lower surface of the outer circumferential lower clamp housing 2203 to support the outer circumferential lower clamp housing 2203 and eliminate friction between the moisture absorbing and dehumidifying member 2200 and the bottom surface of the lower housing 2700.

[0093] Note that the number of rigid rollers 2723 is not limited in the embodiments of the present disclosure. Those skilled in the art may provide four rigid rollers 2723 as shown in FIG. 15, or may provide a greater or lesser number of rigid rollers 2723.

[0094] 16 and 17 are exploded views of the lower housing first attachment portion 2720 and the upper housing 2820, respectively, for attaching the moisture absorbing and dehumidifying member 2200. Fig. 18 is an exploded view of the first attachment portion 2720, the upper housing 2820, and the moisture absorbing and dehumidifying member 2200 attached.

[0095] According to some embodiments, as shown in FIGS. 16 to 18 , lower housing 2700 of drying device 2000 may be an integrated lower housing, on which first mounting portion 2720 for mounting moisture absorbing and dehumidifying member 2200 is provided. Drying device 2000 further includes a separate upper housing 2820 for mounting moisture absorbing and dehumidifying member 2200. Upper housing 2820 includes first air outlet 2902 of the moisture absorption passage, as well as a circular second mounting portion 2821 for mounting moisture absorbing and dehumidifying member 2200. Moisture absorbing and dehumidifying member 2200 is rotatably connected to minor axis 2721 of first mounting portion 2720, such that moisture absorbing and dehumidifying member 2200 is rotatably connected in the substantially cylindrical space formed by first mounting portion 2720 and second mounting portion 2821.

[0096] 16 to 24, a first separator 2725 is provided on the first mounting portion 2720, and a second separator 2822 is provided on the second mounting portion 2821. After the lower housing 2700 is fixedly connected to the upper housing 2820, the second separator 2822 is located directly above the first separator 2725, thereby dividing the cylindrical space in which the moisture absorbing and dehumidifying member 2200 is located into a moisture absorbing region 2907 and a regenerating region 2908. In other words, the first separator 2725 and the second separator 2822 divide the moisture absorbing and dehumidifying rotating disk 2201 into the moisture absorbing region 2907 and the regenerating region 2908. The circulating airflow flows from below the moisture absorbing and dehumidifying rotating disk 2201 into the moisture absorbing region 2907 of the moisture absorbing and dehumidifying rotating disk 2201, and the moisture absorbing region 2907 is used to absorb moisture in the circulating airflow. The dehumidifying flow flows from above the moisture absorbing and dehumidifying rotating disk 2201 into the regeneration area 2908 of the moisture absorbing and dehumidifying rotating disk 2201, and is used to discharge the moisture absorbed by the moisture absorbing and dehumidifying rotating disk 2201, thereby realizing the regeneration and reuse of the moisture absorbing and dehumidifying rotating disk 2201.

[0097] According to some embodiments, as shown in FIGS. 16 and 18 , at least one third separator 2726 is further provided on the first mounting portion 2720 of the lower housing 2700. The at least one third separator 2726 divides the moisture absorption region 2907 into at least two portions, a first moisture absorption region 2907-1 and a second moisture absorption region 2907-2, thereby separating the circulating airflow flowing into the moisture absorption region 2907. After the circulating airflow enters the space between the lower housing 2700 and the moisture absorption and dehumidification member 2200 via the circulation fan, the third separator 2726 divides the circulating airflow relatively uniformly into at least two portions (i.e., the airflow rates in the two portions are substantially the same). This allows the circulating airflow to flow more toward the periphery of the moisture absorption and dehumidification member 2200 under the action of centrifugal force, avoiding the problem of the airflow decreasing toward the center. This embodiment improves the moisture absorption efficiency of the moisture absorption and dehumidification member 2200 and achieves uniform and stable moisture absorption.

[0098] 16 and 18 , a first sealing member is provided between moisture absorption and dehumidification member 2200 and first separation member 2725 of lower housing 2700, and the first sealing member is fixed to the upper end surface of first separation member 2725 (e.g., by screws, fasteners, adhesive, etc.). The first sealing member may include, for example, a sealing strip 2728 and a metal pressing piece 2727. Sealing strip 2728 may be made of, for example, rubber, foam, leather strap, or other material. Metal pressing piece 2727 may be connected to sealing strip 2728 by screws, adhesive, etc., to fix sealing strip 2728 to first separation member 2725.

[0099] Similar to the above embodiment, as shown in FIGS. 17 and 18 , a second sealing member is provided between moisture absorption and dehumidification member 2200 and second separation member 2822 of upper housing 2820, and the second sealing member is fixed to the lower end surface of second separation member 2822 (e.g., by screws, fasteners, adhesive, etc.) and is located directly above first sealing members 2727 and 2728. The second sealing member may include, for example, a seal ring 2824 and a metal pressing piece 2823. Seal ring 2824 may be made of, for example, rubber, foam, or a leather strap. Metal pressing piece 2823 may be connected to seal ring 2824 by screws or adhesive, thereby fixing seal ring 2824 onto second separation member 2822.

[0100] First sealing members 2727, 2728 and second sealing members 2823, 2824 can realize dynamic sealing between moisture absorbing and dehumidifying member 2200 and lower housing 2700, i.e., moisture absorbing region 2907 and regenerating region 2908 are separated and a relative seal is maintained during the rotation of moisture absorbing and dehumidifying member 2200. The circulating airflow in moisture absorbing region 2907 that passes through first separating member 2725 and second separating member 2822 to reach regenerating region 2908 is minimized, and the dehumidifying airflow in regenerating region 2908 that passes through first separating member 2725 and second separating member 2822 to reach moisture absorbing region 2907 is also minimized.

[0101] According to some embodiments, the gap between the first and second sealing members, particularly the sealing strip 2728 and the sealing ring 2824, and the moisture absorbing and dehumidifying member 2200 can be set reasonably small, for example, 0.2 to 5 mm, or 0.6 to 0.8 mm. This prevents contact between the first and second sealing members during rotation of the moisture absorbing and dehumidifying rotating disk, thereby preventing increased rotational resistance and achieving a good dynamic sealing effect. FIG. 19 shows an exemplary fastening method for the integrated lower housing 2700 and the upper housing 2820 of the moisture absorbing and dehumidifying member 2200. As shown in FIG. 19, a housing seal ring 2724 is provided at the connection portion of the first mounting portion 2720 of the upper housing 2820 and the lower housing 2700. The housing seal ring 2724 is used to ensure the sealing of the space containing the moisture absorbing and dehumidifying member 2200. The housing seal ring 2724 may be, for example, a rubber gasket or a silicone gasket. A groove for mounting a housing seal ring 2724 is provided in the first mounting portion 2720 of the upper housing 2820 or the lower housing 2700. The housing seal ring 2724 is mounted in the groove, and the upper housing 2820 and the first mounting portion 2720 are snapped together and then fastened with bolts.

[0102] 6, an integrated lower housing 2700 of drying apparatus 2000 is provided with a mounting portion 2730 for mounting regenerative fan 2400. Mounting portion 2730 cooperates with a separate upper housing corresponding to regenerative fan 2400, allowing regenerative fan 2400 to be secured to mounting portion 2730 of lower housing 2700. Regenerative fan 2400 may be, for example, a packaged fan module.

[0103] Under the action of the regeneration fan 2400, a dehumidified airflow is formed in the regeneration passage. FIG. 20 illustrates the flow direction of the dehumidified airflow in an embodiment of the present disclosure. As shown in FIG. 20, under the action of the regeneration fan 2400, the dehumidified airflow enters the air inlet of the regeneration fan 2400 (indicated by arrow A), passes through the regeneration fan 2400, and enters the heating module 2500 via the first connecting member 2909 (indicated by arrows B and C). The heating module 2500 is located above the regeneration area of ​​the moisture absorption and dehumidification rotating disk 2201. After entering the heating module 2500, the dehumidified airflow passes from top to bottom through the regeneration area of ​​the moisture absorption and dehumidification rotating disk 2201 (indicated by arrow D), and then enters the condensation module 2600 (indicated by arrow E). The air outlet of the housing (not shown in FIG. 20) of the condensation module 2600 communicates with the air inlet of the regeneration fan 2400 via the second connecting member 2910, so that the regeneration passage forms a closed loop. The dehumidified air flow after condensation by condensing module 2600 flows again into the air inlet of regeneration fan 2400 via second connecting member 2910 (indicated by arrow A), and the dehumidified air flow can circulate within the regeneration passage. The closed-loop regeneration passage prevents interaction between the dehumidified air flow and the external environment of the combined washer-dryer washing machine, thereby reducing any impact on the external environment (such as the impact on the humidity of the external air).

[0104] In some other embodiments, the regeneration passage may be an open-loop passage. For example, in the embodiment shown in FIGS. 1 and 5 , a second air outlet 102 and a second air inlet 103 are provided on the side of the housing 10 of the combined washer-dryer washing machine. The second air outlet 102 is connected to the air outlet end 621 of the regeneration passage 202, and the second air inlet 103 is connected to the air inlet end 622 of the regeneration passage 202. In this embodiment, a condensation module is provided in at least one of the air outlet end 621 and the air inlet end 622. The condensation module provided in the air outlet end 621 can condense and dry the dehumidified airflow discharged to the outside, thereby reducing the humidity of the discharged airflow and reducing its impact on the external environment. The condensation module provided in the air inlet end 622 can dry the external airflow flowing into the regeneration passage, improving the dehumidification effect of the regeneration area.

[0105] According to some embodiments, an electric auxiliary heating assembly may be provided at the air inlet end 622. The electric auxiliary heating assembly is used to preheat the dehumidified air flow entering the regeneration passage 202 to improve the dehumidification effect of the regeneration zone.

[0106] During rotation of the humidification / dehumidification rotating disk 2201, each section of the humidification / dehumidification rotating disk 2201 rotates from the absorbing passage to the regenerating passage, then from the regenerating passage to the absorbing passage. Thus, the section of the humidification / dehumidification rotating disk 2201 in the absorbing region absorbs moisture from the humid circulating airflow in the absorbing passage, and then rotates to the regenerating region. The heating module 2500 heats the section, causing the moisture in the section to rapidly desorb into the dehumidified airflow, resulting in a high-temperature, water-vapor-containing airflow (i.e., a high-temperature humid airflow). The condensation module 2600 condenses the high-temperature humid airflow into a low-temperature dry airflow and discharges the condensed water from the condensation module 2600 through a condensed water outlet. The low-temperature dry airflow obtained after treatment by the condensation module 2600 re-enters the air inlet of the regenerating fan 2400 (corresponding to the closed-loop regenerating passage) or is discharged to the outside (corresponding to the open-loop regenerating passage).

[0107] The heating module 2500 is disposed above the regeneration area of ​​the moisture absorbing and dehumidifying rotating disk 2201 and covers the regeneration area. FIGS. 21 and 22 show exploded and three-dimensional views, respectively, of the heating module 2500 and the related structure of the regeneration fan 2400. As shown in FIGS. 20 to 28, the regeneration fan 2400 is fixed to the regeneration fan upper housing 2410 and the regeneration fan lower housing 2420. The heating module 2500 communicates with the air outlet of the regeneration fan 2400 via a first connecting member 2909. A first seal gasket 2912 is provided at the connection between the heating module 2500 and the first connecting member 2909. The heating module 2500 is connected to the module upper housing corresponding to the moisture absorbing and dehumidifying member via a third connecting member 2911, for example, to the fan-shaped notch on the top surface of the upper housing 2820 shown in FIG. 18. The air inlet of the regenerative fan 2400 is connected to the housing of the condensation module 2600 (not shown in FIGS. 21 and 28) by a second connecting member 2910. A second sealing gasket 2913 is provided at the connection between the second connecting member 2910 and the condensation module 2600 housing.

[0108] FIGS. 23 and 24 show a three-dimensional view and an exploded view, respectively, of first connecting member 2909, and FIGS. 25 and 26 show a three-dimensional view and an exploded view, respectively, of second connecting member 2910. As shown in FIGS. 23 to 32, first connecting member 2909 may be divided into two upper and lower parts, i.e., first connecting member upper part 2914 and first connecting member lower part 2915. First connecting member upper part 2914 and first connecting member lower part 2915 may be machined separately and then fastened together by welding or bolts to obtain first connecting member 2909. Similarly, second connecting member 2910 may be divided into two upper and lower parts, i.e., second connecting member upper part 2916 and second connecting member lower part 2917. Second connecting member upper part 2916 and second connecting member lower part 2917 may be machined separately and then fastened together by welding or bolts to obtain second connecting member 2910.

[0109] Dividing first connecting member 2909 and second connecting member 2910 into two parts reduces the difficulty of processing them and ensures their manufacturability. Furthermore, the shapes of first connecting member 2909 and second connecting member 2910 are determined based on the structure and arrangement of components in the regeneration passage, such as regeneration fan 2400, heating module 2500, and condensation module 2600, which allows them to cooperate with other components in the regeneration passage to seal the regeneration passage and adjust the flow direction of the dehumidification air.

[0110] The first connecting member 2909 may be a flexible integrated structure, with the air inlet and air outlet portions at both ends being deformable to extend into the air outlet of the condensation module housing and the air inlet housing of the regeneration fan, and after deformation, form a sealed connection by bolting.

[0111] FIG. 27 shows a schematic diagram of the mounting position of the heating module 2500 on the upper housing 2820. As shown in FIG. 27, the heating module 2500 is mounted on the upper housing 2820, and the heating module 2500 and the upper housing 2820 are provided with an insulating ring 2918 and a second sealing ring 2919. The insulating ring 2918 may be formed from an insulating or thermally insulating material. In some embodiments, the insulating ring 2918 may be a metallic material. The second sealing ring 2919 may be made of a material such as silica gel, rubber, foam, etc.

[0112] 27, second seal ring 2919 covers insulating ring 2918, and second seal ring 2919 is in direct contact with upper housing 2820 and insulating ring 2918. The regeneration region of the moisture absorbing and dehumidifying rotating disk is located below heating module 2500. By providing insulating ring 2918 and second seal ring 2919 on heating module 2500 and upper housing 2820, the moisture absorbing and dehumidifying rotating disk can be spatially divided into a moisture absorbing region and a regeneration region, allowing the dehumidifying flow to pass smoothly through the moisture absorbing and dehumidifying rotating disk.

[0113] Note that, due to the high temperature of the heating module 2500, if the heating module 2500 comes into direct contact with the upper housing 2820 (the upper housing 2820 may be made of, for example, a plastic material), deformation or damage to the upper housing 2820 may occur over time. By providing the insulating ring 2918 and the second sealing ring 2919, a buffer zone for temperature transfer is formed between the heating module 2500 and the upper housing 2820, and deformation or damage to the upper housing 2820 due to high temperatures can be avoided.

[0114] 28 to 30 respectively show a three-dimensional view of heating module 2500, a schematic view of mesh plate 2550, and a bottom view of heating module 2500. As shown in Figs. 28 to 30, heating module 2500 includes a sector-shaped housing 2510, a mesh plate 2520 provided in sector-shaped housing 2510, and a heating pipe 2530. Heating pipe 2530 is provided below mesh plate 2520, and a plurality of air holes 2521 are provided on mesh plate 2520.

[0115] An air inlet 2540 is opened on the circumferential or radial side of sectorial housing 2510, and the dehumidified airflow flowing out from first connecting member 2909 (see FIGS. 20 to 28) flows from air inlet 2540 into the space above mesh plate 2520 in sectorial housing 2510, then passes through mesh holes 2521 on mesh plate 2520, is heated by heating pipe 2530, and then flows downward into the regeneration area on the moisture absorbing and dehumidifying rotating disk. After being heated by heating pipe 2530, the high-temperature dehumidified airflow can desorb moisture from the regeneration area.

[0116] According to some embodiments, the diameters of the plurality of air holes 2521 on the mesh plate 2520 do not have to be the same. The diameters of the plurality of air holes 2521 can be gradually reduced along the direction of the dehumidified airflow in the heating module 2500. This allows the dehumidified airflow to pass uniformly through the mesh plate 2520, and the heating tube 2530 to adjust the airflow so that the dehumidified airflow can be uniformly heated. For example, as shown in FIG. 28 , when the air inlet 2540 is located on the periphery of the sector-shaped housing 2510, the direction of the dehumidified airflow inside the sector-shaped housing 2510 is from the periphery toward the center. Accordingly, the diameters of the plurality of air holes 2521 on the mesh plate 2520 tend to decrease in the direction from the periphery toward the center of the sector-shaped housing, allowing the heating tube 2530 to adjust the airflow so that the dehumidified airflow can be uniformly heated.

[0117] In other embodiments, air inlet 2540 may be provided on the radial side of sector-shaped housing 2510. In this case, the dehumidified airflow flows inside sector-shaped housing 2510 in a direction substantially perpendicular to the radius (circumferential direction), in other words, in a direction from the radial side where the air inlet is located to the other radial side of sector-shaped housing 2510. Accordingly, the diameter of multiple air holes 2521 on mesh plate 2520 tends to decrease in the direction from the radial side where the air inlet is located to the other radial side. As a result, the airflow rate of mesh plate 2520 can be adjusted so that heating pipe 2530 uniformly heats the dehumidified airflow, and the heated high-temperature dehumidified airflow uniformly dehumidifies the playback area of ​​the moisture absorption and dehumidification rotating disk, thereby improving the dehumidification effect.

[0118] According to some embodiments, as shown in FIG. 30 , the heated pipe 2530 is not disposed directly below the air hole 2521, but is disposed offset from the air hole 2521 toward the center of the sectorial housing. Because the position of the heated pipe 2530 is offset to a certain extent from the air hole 2521, the heated pipe 2530 does not create significant resistance to the dehumidified flow passing through the air hole 2521. Furthermore, when the dehumidified flow enters the air inlet 2540 and passes through the air hole 2521, the speed of the dehumidified flow exists in a direction from the circumference toward the center of the sectorial housing. By disposing the heated pipe 2530 at a position offset from the air hole 2521 toward the center of the sectorial housing, the dehumidified flow passing through the air hole 2521 can be made to directly face the heated pipe 2530, thereby improving the heating efficiency of the heated pipe 2530 with respect to the dehumidified flow.

[0119] 28 and 30 , the bottom wall of the sector-shaped housing 2510 extends outward to form a third mounting portion 2550. The heating module 2500 further includes a temperature sensor 2560 wrapped in a thermally conductive sheet 2570. The temperature sensor 2560 is mounted on the third mounting portion 2550 after being wrapped in the thermally conductive sheet 2570.

[0120] Temperature sensor 2560 is used to detect the temperature of heating module 2500 and realize on / off control of heating pipe 2530. It should be understood that the temperature within heating module 2500 is unstable because the dehumidified airflow after heating may cause turbulence within heating module 2500. If temperature sensor 2560 is directly used to detect the temperature of the airflow within heating module 2500, the temperature value detected by temperature sensor 2560 will be scattered and unstable, which is detrimental to effective control of heating pipe 2530. By locating temperature sensor 2560 within thermal conduction sheet 2570, the temperature within heating module 2500 is first transferred to thermal conduction sheet 2570 by thermal conduction, and temperature sensor 2560 detects the temperature of thermal conduction sheet 2570. The temperature of thermal conduction sheet 2570 is more stable than the temperature of the airflow. Therefore, compared with the case where the temperature sensor 2560 directly detects the temperature of the airflow, the temperature sensor 2560 detects the temperature value of the thermal conduction sheet 2570, thereby improving the stability and accuracy of temperature detection and effectively controlling the heating pipe 2530.

[0121] As described above, the heating module 2500 heats the dehumidified airflow to obtain a high-temperature airflow. The high-temperature airflow desorbs moisture from the regeneration area of ​​the hygroscopic and dehumidifying rotary disk, producing a high-temperature humid airflow. The high-temperature humid airflow obtained by heating the high-temperature humid airflow in the condensation module 2600 continues to flow into the condensation module 2600, where it is condensed into a low-temperature dry airflow, and the condensed water is discharged from the condensation module 2600 through the condensed water outlet. The low-temperature dry airflow obtained by processing in the condensation module 2600 re-enters the air inlet of the regeneration fan 2400 (corresponding to the closed-loop regeneration path) or is discharged to the outside (corresponding to the open-loop regeneration path).

[0122] FIG. 31 shows a schematic diagram of a fastening system between the condensing module 2600 and the lower housing 2700. As shown in FIG. 31, the condensing module upper housing 2830 cooperates with a mounting portion 2740 (i.e., the condensing module lower housing) for mounting the condensing module in the lower housing 2700. The condensing module upper housing 2830 encases the condensing module 2600 and presses a sealing strip 2920 around the condensing module 2600 downward to seal and secure it to the mounting portion 2740. The condensing module upper housing 2830, together with the mounting portion 2740, forms a complete housing for the condensing module 2600, i.e., the condensing module housing. An air outlet 2631 is formed on the condensing module housing, and the air outlet 2631 is connected to the air inlet of the regenerative fan 2400 by a second connecting member 2910 (see FIGS. 20 to 28).

[0123] Figure 32 shows a cross-sectional view of the condensation module housing 2630. As shown in Figure 32, the high-temperature, high-humidity dehumidified air flow passing through the regeneration area 2908 enters the condensation module housing 2630 (indicated by arrow A), undergoes a drying process in the condensation module 2600 (not shown in Figure 32) (indicated by arrow B), and exits through the air outlet 2631 to the second connecting member 2910 (indicated by arrow C).

[0124] 32, a baffle plate 2632 is provided on the bottom of the condensation module housing 2630 near the air outlet 2631. The baffle plate 2632 improves the condensation effect of the condensation module 2600, and ensures that the dehumidified airflow is sufficiently dried by the condensation module 2600. For example, the baffle plate 2632 can prevent the dehumidified airflow entering the condensation module housing 2630 from directly flowing out through the gap between the bottom of the condensation module 2600 and the condensation module housing 2630 without passing through the condensation module 2600, which can prevent the airflow in this area from being condensed and dried.

[0125] As shown in Fig. 31 , a condensation water pipe 2640 for circulating condensed water is provided in the condensation module 2600. The condensation water pipe 2640 further has a water inlet 2610 and a water outlet 2620. The direction indicated by arrow A in Fig. 31 is the direction of dehumidification flow within the condensation module 2600.

[0126] According to some embodiments, the condensate pipe 2640 may be provided with a sensor for detecting the condensate status, such as a temperature sensor or a flow rate sensor. Alternatively, an induction sensor may be provided on the outside of the condensate water inlet pipe to detect whether condensate is flowing through the condensate pipe 2640. Based on the status data detected by the sensor, the water flow in the condensate pipe 2640 may be adjusted or an alarm may be sent, thereby ensuring the normal operation of the condensation module 2600 and improving the condensation effect. For example, if the temperature sensor detects that the condensate temperature is too high, the current condensation effect may be low, and the condensate flow rate may be appropriately increased to lower the condensate water temperature and improve the condensation effect. For example, if the flow rate sensor detects that the condensate flow rate is too low, there may be a risk of liquid leakage from the condensate pipe 2640, and an alarm message may be issued to prompt the user to inspect or repair the condensate pipe 2640. Of course, temperature sensors may be provided at the air inlet and / or air outlet of the condensation module housing, and whether the condensation module is operating normally may be determined based on the temperature detection value, the temperature detection difference, or the temperature difference between the air inlet and the air outlet.

[0127] According to some embodiments, the condensate pipe 2640 may be a serpentine pipe, as shown in FIG. 31 . In the example of FIG. 31 , the condensate pipe 2640 is arranged in a serpentine shape within the condensing module 2600, thereby increasing the contact area between the dehumidified flow and the condensate pipe 2640 and enabling the dehumidified flow to be sufficiently condensed. As shown in FIG. 31 , the condensing module 2600 includes a first side and a second side that face each other in the flow direction of the dehumidified flow (see arrow A), where the first side is located downstream of the second side. In one example (not shown), the water inlet 2610 and the water outlet 2620 of the condensate pipe 2640 are all located on a side wall of the condensing module 2600, which connects the first and second sides of the condensing module 2600, with the water inlet 2610 and the water outlet 2620 being closer to the first side than to the second side. In this example, the condensate pipe 2640 extends from the water inlet 2610 along a first zigzag path toward the second side of the condensing module 2600 to a location away from the first side, and then extends from there along a second zigzag path toward the first side to the water outlet 2620, where the length of the first zigzag path is greater than the length of the second zigzag path, e.g., twice the length of the second zigzag path. This arrangement is advantageous because the temperature of the condensate gradually increases from the first side of the condensing module 2600 to the second side due to heat generation by the dehumidifying stream, and conversely, the temperature of the condensate gradually decreases from the second side of the condensing module 2600 to the first side due to heat absorption by the condensing stream, maintaining a constant temperature difference between the dehumidifying stream and the condensate throughout the condensation process, thereby improving the condensation effect.
