However, because the temperature of the entire evaporator is constant, the evaporator's moisture absorption capacity for the moist air decreases as the humid air evaporates, resulting in problems such as low moisture absorption efficiency, long drying times, and high power consumption. In addition, while some methods use condensate rinse or direct dehumidification of moist air using a condenser, the treated air still contains a large amount of moisture and requires the air to be heated, cooled, dehumidified, and then heated again for recycling, resulting in low dehumidification efficiency and high power consumption.

[0017] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific examples. However, the embodiments of the present application and the specific features of the embodiments are merely detailed descriptions of the technical solutions of the embodiments of the present application and do not limit the technical solutions of the present application. As long as they are not contradictory to each other, the embodiments of the present application and the technical features of the embodiments can be combined with each other.

[0018] Compared to the current prior art, the purpose of this application is to provide a drying module and a washing / drying combination washing machine that solves the problems of the prior art, namely, that the airflow after dehumidification still contains a large amount of moisture, and that the airflow needs to be heated, cooled to dehumidify, and then heated again for recycling, resulting in low dehumidification efficiency and high power consumption.

[0019] As shown in Figures 1 to 32, in order to solve the above problems, one embodiment of the present application provides a drying module comprising: a circulation module 10 that communicates with the drum of a combined washer-dryer washing machine and is used to dehumidify by outputting the wet circulating airflow from the drum to a portion of the circulating airflow path of a dehumidifying module 20; a dehumidifying module 20 that communicates with the circulation module 10 and the drum and is used to adsorb moisture in the wet circulating airflow from the drum; a regeneration module 30 that is attached to the dehumidifying module 20, communicates with at least a portion of the dehumidifying module 20, outputs a regeneration airflow to the dehumidifying module 20, and is used to desorb moisture absorbed by the dehumidifying module 20; and a housing provided with accommodation areas for accommodating the circulation module 10, the dehumidifying module 20, and the regeneration module 30, respectively.

[0020] In this embodiment, the portion of the dehumidifying module 20 located in the circulating airflow path is used to adsorb moisture in the circulating airflow, and the portion of the dehumidifying module 20 located in the regenerating airflow path has moisture desorbed by the regenerating module 30. Here, the circulating module 10 functions as a power source for circulating the airflow between the drum and the dehumidifying module 20. The circulating module 10 transports the moist circulating airflow from the drum to the dehumidifying module 20 for adsorption and dehydration. The dehumidifying module 20 adsorbs moisture from the moist circulating airflow from the drum and outputs a dry circulating airflow to the drum. The regenerating module 30 is connected to the dehumidifying module 20 and outputs a dry regenerating airflow to the portion of the dehumidifying module 20 located in the regenerating airflow path, desorbing moisture from the portion of the dehumidifying module 20 located in the regenerating airflow path and restoring its moisture adsorption capacity. The condensing module 40 is connected to the regenerating air outlet of the regenerating module 30 and is used to condense the regenerating airflow output from the regenerating module 30 to form a low-temperature dry regenerating airflow and discharges condensed water formed during the condensation process.

[0021] In some embodiments, the drum may be the containment device.

[0022] As shown in Figures 1 and 2, preferably, the drying module further includes a condensation module 40 used to condense the moisture desorbed by the dehumidification module 20, and the housing further includes a condensation module accommodating area, and the accommodating areas for the circulation module 10, the dehumidification module 20, and the condensation module 40 are integrally molded.

[0023] The condensation module 40 communicates with the regeneration air outlet of the regeneration module 30 and is used to condense the regeneration airflow output from the regeneration module 30 to form a low-temperature, dry regeneration airflow, where the dehumidification module 20 is fixedly connected to the frame, and the circulation module 10 and / or the condensation module 40 are fixedly connected to the drum. Alternatively, at least one of the dehumidification module 20, the circulation module 10, and the condensation module 40 is fixedly connected to the frame, and the other modules are fixedly connected to the drum.

[0024] The dehumidifying module 20, the circulation module 10, and the condensing module 40 are each independent modules, and the dehumidifying module 20 and the attached regeneration module 30 are fixedly connected to the frame to reduce or eliminate the impact of drum vibration on the dehumidifying module 20, and at least one of the circulation module 10 and the condensing module 40 is fixedly connected to the drum. Of course, the regeneration fan 301 communicating with the regeneration module 30 can also be selectively fixed to the frame or the drum. Since the circulation module 10, the condensing module 40, the regeneration fan 301, etc. are sensitive to vibration, they can be installed according to the actual situation and spatial arrangement needs.

[0025] As shown in FIGS. 1 and 2, preferably, the dehumidifying module 20 includes a turntable 200 and a turntable upper housing 210, at least a portion of the turntable 200 is used to adsorb moisture in the humid circulating airflow, an airflow passage is formed between the top wall and the bottom wall of the turntable 200 and the turntable upper housing 210, a regeneration module 30 mounting portion is provided on the turntable upper housing 210, the circulation module 10 is located upstream or downstream of the dehumidifying module 20, the regeneration module 30 is mounted on the regeneration module 30 mounting portion, and the regeneration module 30 is adjacent to at least another portion of the turntable 200 to evaporate the moisture adsorbed by the turntable 200, and the turntable As the turntable 200 rotates continuously within the turntable upper housing 210, the humid circulating airflow passes through the airflow passages formed between the turntable 200 and the top and bottom walls of the turntable upper housing 210. At least a portion of the turntable 200 comes into contact with the humid circulating airflow and adsorbs moisture in the circulating airflow, forming a dry circulating airflow. The dry circulating airflow passes through the objects to be dried in the drum, regenerating a humid circulating airflow. When the turntable 200 rotates into the area where the regeneration module 30 attached to the turntable upper housing 210 is located, the regeneration module 30 evaporates the moisture adsorbed by the turntable 200. This process is repeated until the turntable 200 continuously absorbs moisture in the humid circulating airflow, and the adsorption capacity is restored by the regeneration module 30. Preferably, the circulation module 10 is located upstream of the dehumidifying module 20, blowing the humid circulating airflow onto the dehumidifying module 20 and circulating the airflow between the dehumidifying module 20 and the drum. The condensation module 40 is in communication with the regeneration module 30 and condenses the regeneration airflow output from the regeneration module 30 to form a low-temperature dry airflow.

[0026] In some embodiments, the turntable upper housing 210 may be the turntable second housing.

[0027] In one embodiment of the present application, the circulation module 10, the dehumidification module 20 and the regeneration module 30 are connected by bellows.

[0028] In one embodiment of the present application, the dehumidifying module 20 further includes an air outlet passage, one end of which communicates with the dehumidifying module 20 and the other end of which communicates with the drum via a first corrugated hose.

[0029] In this embodiment, the dehumidifying module 20 communicates with the interior of the drum via a first corrugated hose, preventing damage to the air outlet passage and the dehumidifying module 20 due to drum rotation. The air outlet passage serves as a passage through which dry air obtained by moisture absorption in the dehumidifying module 20 enters the drum. Optionally, a filtering assembly or a valve is provided in the air outlet passage to prevent impurities or moisture in the drum from entering the dehumidifying module 20 through the air outlet passage and damaging components in the dehumidifying module 20 when the drying module is not in operation.

[0030] In one embodiment of the present application, the circulation module 10 and the condensation module 40 are fixedly connected to the drum, the dehumidification module 20 is connected to the circulation module 10 via a second corrugated hose, the regeneration module 30 is connected to the condensation module 40 via a third corrugated hose, and the circulation module 10 is connected to the drum.

[0031] In this embodiment, the dehumidifying module 20 is fixed to the frame, the circulation module 10 and the condensation module 40 are fixedly connected to the drum, the air inlet of the dehumidifying module 20 communicates with the air outlet of the circulation module 10 via a second corrugated hose, the regeneration module 30 communicates with the air inlet of the condensation module 40 via a third corrugated hose, and the air inlet of the circulation module 10 communicates with the drum air outlet, thereby preventing damage to the dehumidifying module 20, the regeneration module 30, and the circulation module 10 due to different amplitudes and frequencies of drum vibration. The circulation module 10 is fixedly attached to the drum, and the air inlet of the circulation module 10 communicates with the drum and, optionally, the air inlet of the circulation module 10 is fixedly connected to the drum air outlet.

[0032] In one embodiment of the present application, the circulation module 10 is fixedly connected to the drum, the condensation module 40 is fixedly connected to the frame, and the dehumidification module 20 communicates with the circulation module 10 via a second corrugated hose.

[0033] In this embodiment, the dehumidifying module 20 and the condensing module 40 are fixedly attached to the frame, and the circulation module 10 is fixedly attached to the drum. The air inlet of the dehumidifying module 20 communicates with the air outlet of the circulation module 10 via a second corrugated hose, preventing damage to the dehumidifying module 20 and the circulation module 10 due to the different amplitudes and frequencies of vibration between the drum and the frame. The dehumidifying module 20, the condensing module 40, and the regenerating module 30 are all fixedly connected to the frame, so the connection method for the air inlets and air outlets among the three is not limited, but is preferably fixedly connected.

[0034] In one embodiment of the present application, the condensation module 40 is fixedly connected to the drum, the circulation module 10 is fixedly connected to the frame, the regeneration module 30 is in communication with the condensation module 40 via a third corrugated hose, and the circulation module 10 is in communication with the drum via a fourth corrugated hose.

[0035] In one embodiment of the present application, the dehumidifying module 20 further includes an air inlet passage provided in the drum, one end of which is fixedly connected to the drum and the other end of which is connected to the circulation module 10. A filter assembly is provided in the air inlet passage to filter impurities in the circulation airflow. By providing a filter assembly (which may be a filter wire) in the air inlet passage to remove impurities in the circulation airflow, impurities such as lint and dust can be prevented from entering the circulation module 10 and the dehumidifying module 20, thereby preventing clogging of the modules or combustion of impurities. Because impurities such as lint and dust exit the drum, attaching the air inlet passage to the drum facilitates direct filtering of the circulation airflow and prevents clogging of the air inlet passage, the downstream fourth corrugated hose, and the circulation module 10.

[0036] As shown in Figures 1 and 2, in one embodiment of the present application, the regeneration module 30 includes a heating module 302 having a regeneration fan 301 mounting portion at its inlet end, the heating module 302 being used to desorb the moisture adsorbed by the dehumidification module 20, and a regeneration fan 301 attached to the regeneration fan 301 mounting portion, communicating with the condensation module 40, and used to transport the low-temperature dry regeneration airflow formed by condensation by the regeneration module 30 to the heating module 302. The heating by the heating module 302 evaporates the moisture adsorbed by the dehumidification module 20, and the regeneration fan 301 transports the air to the heating module 302 to form a high-temperature regeneration airflow, accelerating the recovery of the moisture adsorption capacity of the dehumidification module 20.

[0037] In one embodiment of the present application, the condensation module 40 is provided with a cooling water inlet, a cooling water outlet, and a condensed water drain, and the cooling water inlet is connected to the water inlet valve on the frame via a first hose. The cooling water outlet and the condensed water drain communicate with the drain pipe of the combined washer-dryer washing machine to directly drain the condensed water or cooling water.

[0038] 2 to 5, the circulation module 10 specifically includes a circulation module housing, an impeller 110, and a circulation motor 120. The circulation module housing is provided with a first air inlet 102 and a first air outlet 103, the impeller 110 is provided within the circulation module housing, the rotation axis of the impeller 110 is parallel to the axis of the first air inlet 102 and is substantially perpendicular to the axis of the first air outlet 103, the circulation motor 120 is fixedly connected to the circulation module housing, and the output shaft of the circulation motor 120 is fixedly connected to the impeller 110. The rotation axis of the impeller 110 corresponds to the first air inlet, that is, the rotation axis of the impeller 110 can pass through the first air inlet 102, so that the impeller 110 can drive the airflow at the first air inlet 102 head-on and make the airflow flow into the circulation module housing, and the airflow can be quickly sucked into the circulation module housing without increasing the rotation speed of the impeller 110. When the impeller 110 is driven to rotate by the circulation motor 120, centrifugal force is generated along the outer periphery of the impeller 110, and the airflow inside the impeller 110 flows along the direction of the centrifugal force. At this time, the airflow is scattered from the outer periphery of the impeller 110, changing the flow direction of the airflow, and negative pressure is generated at the rotation axis of the impeller 110 and its vicinity, and the airflow sucked into the first air inlet 102 increases. Therefore, by designing the circulation power so that the circulation motor 120 rotates the impeller 110 to create negative pressure and blow air, damage caused by a large wind force directly impinging on other components can be effectively avoided. While conventional fans generally incur high losses when changing the flow direction of airflow, the circulation module provided by the embodiments of the present application provides power to change the flow direction of airflow, allowing for greater flexibility in implementing the layout of the circulation module.

[0039] In an alternative embodiment, the circulation module housing includes a circulation module lower housing 112 having a recessed first impeller accommodating area and a circulation module upper housing 111 having a recessed second impeller accommodating area, the circulation module lower housing 112 and the circulation module upper housing 111 being matingly connected, the first impeller accommodating area and the second impeller accommodating area forming an impeller accommodating cavity. The impeller 110 is located in the impeller accommodating cavity, which has a circular shape larger than the outer diameter of the impeller 110, and the axis of the impeller accommodating cavity is parallel to the rotation axis of the impeller 110. The airflow output by the rotation of the impeller 110 may be guided to flow out through the inner walls of the circulation module lower housing 112 and the circulation module upper housing 111.

[0040] In some embodiments, circulation module upper housing 111 may be the circulation module second housing.

The circulation module lower housing 112 may be formed by bending the bottom plate upward, and similarly, the circulation module upper housing 111 may be formed by bending the top plate downward. When the circulation module lower housing 112 and the circulation module upper housing 111 are assembled, the first protrusion presses the sealing gasket 113 in the first groove, deforming the sealing gasket 113 and achieving excellent sealing effect between the circulation module lower housing 112 and the circulation module upper housing 111.

[0042] In some embodiments, circulation module lower housing 112 may be the circulation module first housing.

[0043] In an alternative embodiment, the impeller 110 includes an impeller body 1101 and a fixed ring 1103 axially opposed to the impeller body 1101, the impeller body 1101 extending toward the fixed ring 1103 and having an accommodating cavity for accommodating a circulation motor, one end of the circulation motor 120 being arranged in the accommodating cavity, the output shaft of the circulation motor 120 being fixedly connected to the bottom of the impeller body 1101, and both ends of the blades 1102 being fixedly connected to the impeller body 1101 and the fixed ring 1103, respectively, the blades 1102 being arranged at intervals around the impeller body 1101, and the blades 1102 being arranged inclined forward along the rotation direction of the impeller. The impeller body 1101 includes a top cover plate, and one longitudinal end of the blades 1102 is fixedly connected to the cover plate, so that the airflow sucked in from the bottom of the impeller is blocked by the cover plate and output in the radial direction of the impeller. The impeller body 1101 extends in the direction of the blades 1102, and a recessed housing cavity is provided within the impeller body 1101. One end of the circulation motor 120 is embedded in the housing cavity, so that the axial length of the circulation fan as a whole is shortened, and the overall mechanical length of the circulation fan can be reduced. The blades 1102 are tilted forward along the rotation direction of the impeller, which improves the air outlet efficiency of the impeller, enhances the noise reduction effect of the fan, and contributes to improving the energy efficiency of the fan.

The dehumidifying module includes a moisture-absorbing and dehumidifying member located in the second circulation passage and used to adsorb moisture in the moist circulating airflow in the drum. The regeneration module 30 includes a regeneration member located adjacent to the moisture-absorbing and dehumidifying member and used to at least partially discharge the moisture adsorbed by the moisture-absorbing and dehumidifying member.

To enable continuous and repeated use of the moisture-absorbing and dehumidifying member, a regenerating member is used to discharge the moisture adsorbed by the moisture-absorbing and dehumidifying member, which may be, for example, a heating member or an ultrasonic member, and the moisture adsorbed by the moisture-absorbing and dehumidifying member is removed by methods such as heating or ultrasonic dehumidification.

[0052] It should be noted that proximity may be understood to mean adjacently located.

[0053] A third aspect of the present application provides a washing and drying combination washing machine including the drying device described above.

[0054] The combined washer-dryer washing machine further includes a drum, the axis of which is arranged horizontally, a circulation module attached to the top of the drum, and a first air inlet 102 arranged below and connected to the air outlet of the drum via a corrugated hose 50. The installation of the corrugated hose 50 reduces vibrations caused by the drum.

[0055] In some embodiments, the first airflow passage communicates with the drum air outlet, and the second airflow passage communicates with the drum air inlet, and the wet circulating airflow inside the drum passes through the first airflow passage from top to bottom through the moisture-absorbing area of ​​the turntable 200 and reaches the second airflow passage, whereby moisture in the wet circulating airflow is adsorbed to form a dry circulating airflow.

[0056] In some embodiments, the lower housing 100 includes a circulation module lower housing 112, in which a circulation fan accommodating area is provided, and the circulation fan accommodating area is connected to the first turntable accommodating area, where the circulation fan is installed in the circulation fan accommodating area, the air inlet of the circulation fan is connected to the drum air outlet, and the air outlet of the circulation fan is connected to the second airflow passage. The moist circulating airflow discharged from the drum is sucked into the bottom of the turntable accommodating cavity by the circulation fan, thereby accelerating the diffusion of the moist circulating airflow in the second airflow passage and contributing to the circulation of the airflow.

[0057] In some embodiments, the lower housing 100 may be the first housing.

[0058] In some embodiments, the lower housing 100 further includes a turntable lower housing 220, the turntable lower housing 220 having the first turntable receiving area, a first partition member 221 provided within the first turntable receiving area to divide the first turntable receiving area into a dehumidification area and a regeneration area, and the air outlet of the circulation fan communicates with the dehumidification area. A gap is provided between the bottom surface of the turntable 200 and the inner bottom wall of the dehumidification area of ​​the turntable lower housing, forming a second airflow passage. When the turntable 200 is operating, the portion in the dehumidification area can adsorb moisture in the humid circulating airflow that has entered the second airflow passage. During the rotation of the turntable 200, the portion that has adsorbed moisture in the dehumidification area rotates to the regeneration area and is dehydrated and regenerated.

[0059] In some embodiments, the drying module further includes a regeneration module 30 matingly connected to the turntable upper housing 210. The turntable upper housing 210 further includes a substantially fan-shaped regeneration module receiving section, and the regeneration module 30 is attached to the regeneration module receiving section and positioned above the turntable 200. The regeneration module is used, for example, to heat the regeneration airflow and desorb moisture adsorbed by the turntable 200. An airflow space exists inside the regeneration module, forming a third airflow passage. A gap exists between the bottom surface of a portion of the turntable 200 and the inner wall of the regeneration area of ​​the turntable lower housing 220, forming a fourth airflow passage. The regeneration module may include a heater used to heat the regeneration airflow. The heated regeneration airflow passes through the turntable 200 from top to bottom via the third airflow passage and reaches the fourth airflow passage, dehydrating the portion of the turntable 200 in the regeneration area. During the rotation of the turntable 200, moisture adsorption and desorption are repeatedly performed while passing through the dehumidification area and the regeneration area.

[0060] In some embodiments, the turntable lower housing 220 may be the turntable first housing, and the turntable upper housing 210 may be the turntable second housing.

[0061] In some embodiments, the lower housing 100 further includes a condenser module lower housing 420 and a regenerative fan mounting portion 320. The regenerative fan is mounted on the regenerative fan mounting portion 320. The condenser module lower housing 420 has a condenser accommodating area. The condenser accommodating area communicates with the fourth airflow passage and the air inlet of the regenerative fan. The air outlet of the regenerative fan communicates with the third airflow passage. The regenerative airflow is drawn into the third airflow passage by the regenerative fan, passes through the regenerative module from top to bottom, passes through the turntable 200, and reaches the fourth airflow passage to become a high-temperature and humid regenerative airflow. The high-temperature and humid regenerative airflow then sequentially enters the condenser 401 and the regenerative fan to form a closed-loop regenerative airflow. The high-temperature and humid regenerative airflow enters the condenser 401 for heat exchange and cooling. The water vapor in the regenerative airflow is cooled to condensate, which is then discharged through the drain outlet of the condenser 401. The dry, low-temperature regenerative airflow enters the regenerative fan for the next cycle.

[0062] In some embodiments, the condensation module lower housing 420 may be the condensation module first housing.

[0063] In some embodiments, lower housing 100 is molded as a single unit. In an exemplary embodiment, circulation module lower housing 112, turntable lower housing 220, condensation module lower housing 420, and regeneration fan mounting portion 320 are molded as a single unit. Lap joints 51 may be provided around the periphery of lower housing 100, and the lap joints 51 are spaced apart along the circumferential direction of lower housing 100, allowing the entire drying module to be attached to a frame by means of lap joints 51. In this manner, the entire drying module is molded as a single unit, simplifying the assembly process within the combined washer-dryer washing machine and facilitating further optimization of the overall size of the combined washer-dryer washing machine. In order to minimize the overall size of the combined washer-drying machine, the drying module may be mounted on top of the drum, and the drying module is arranged horizontally, i.e., the rotation axes of the turntable 200, the circulation fan, and the regeneration fan are substantially parallel and perpendicular to the rotation axis of the upper housing of the combined washer-drying machine / the drum of the combined washer-drying machine. Therefore, the overall height of the combined washer-drying machine depends on the diameter of the drum and the thickness of the housing arranged above the drum. The circulation fan, regeneration fan, condenser, etc. may all be arranged above the drum, and since the drum is approximately horizontal and cylindrical, more vertical space is secured above and on both sides of the maximum diameter of the drum for installing components such as the circulation fan, regeneration fan, condenser, etc.

[0064] In some embodiments, circulation module lower housing 112 may be the circulation module first housing.

[0065] In some embodiments, lap joints 51 may be provided, for example, on the turntable upper housing 210, the circulation module upper housing 111, and / or the condensation module upper housing 410, to more securely attach the entire dryer module, not all of which are illustrated here.

[0066] In some embodiments, the turntable upper housing 210 may be the turntable second housing, the circulation module upper housing 111 may be the circulation module second housing, and the condensation module upper housing 410 may be the condensation module second housing.

[0067] In some embodiments, the air inlet of the circulation fan is flexibly connected to the drum air outlet, and the turntable upper housing 210 is flexibly connected to the drum air inlet, so that the first airflow passage communicates with the drum air inlet. The flexible connection may be, for example, via a corrugated hose 50, and may be flexibly connected via the drum air inlet and the drum air outlet, preventing drum vibrations from being transmitted to the entire drying module, particularly to the turntable member. The turntable upper housing 210 is provided with an air outlet passage 203, which is transitionally connected to the drum inlet air duct 52. The drum inlet air duct 52 and the drum air inlet may be flexibly connected, for example, via a corrugated hose 50.

[0068] In some embodiments, the first partition member 221 is disposed radially on the turntable lower housing 220, with a roller mounting area located at the center of the first turntable housing area. Due to the radially disposed first partition member 221, the dehumidifying area and the regenerating area are substantially fan-shaped, and the area of ​​the dehumidifying area may be set to be two to three times the area of ​​the regenerating area. The area of ​​the dehumidifying area may be larger than the area of ​​the regenerating area, in which case most of the turntable 200 is located in the dehumidifying area, thereby further improving the moisture absorption efficiency and moisture absorption effect of the turntable 200. To prevent the humid circulating airflow discharged from the drum and the regenerating airflow from colliding with each other, a dynamic sealing effect can be achieved to some extent between the first partition member 221 and the turntable 200. When the turntable 200 rotates in the regeneration area, the regeneration airflow heats that part of the turntable 200, causing the moisture in that part to quickly evaporate and desorb, and then being carried to the condenser by the regeneration airflow, so that the turntable 200 always has good water absorption ability and can improve the moisture absorption efficiency and effect.

[0069] In an exemplary embodiment, a first turntable accommodating area may be provided in the turntable lower housing 220, which includes a bottom plate and a circumferential sidewall protruding from the bottom plate, and the recessed portion is the first turntable accommodating area. Similarly, a second turntable accommodating area may be provided in the turntable upper housing 210, which includes a second partition member 211 formed by the top wall, circumferential sidewall, and radial sidewall of the upper housing corresponding to the position of the first partition member 221 of the turntable upper housing 210. The turntable upper housing 210 is disposed opposite the recessed portion structure of the turntable lower housing 220. When the turntable upper housing 210 is mated and connected to the turntable lower housing 220, the first turntable accommodating area and the second turntable accommodating area form a turntable accommodating cavity, and airflow passes through the turntable accommodating cavity, thereby sealingly connecting the turntable upper housing 210 and the turntable lower housing 220. For example, a groove or flange may be provided on turntable upper housing 210 or turntable lower housing 220, with a sealing strip provided in the groove, and when turntable upper housing 210 is mated and connected to turntable lower housing 220, the flange presses the sealing strip in the groove to achieve sealing. The mating connection between circulation module lower housing 112 and circulation module upper housing 111 forms a circulation fan accommodating cavity, and the mating connection between condensation module lower housing 420 and condensation module upper housing 410 forms a condenser accommodating cavity.

[0070] In some embodiments, the first partition member 221 includes at least a first partition body 2211 and a second partition body 2212, and the first partition body 2211 and the second partition body 2212 are all arranged along the radial direction of the turntable lower housing 220, one end of the first partition body 2211 and the second partition body 2212 is connected to the side inner wall of the turntable lower housing 220, and the other ends of the first partition body 2211 and the second partition body 2212 intersect at the center position of the turntable lower housing to form the rotation axis area of ​​the turntable 200, so that the first partition member 221 is formed in a V shape as a whole, and the intersection of the first partition body 2211 and the second partition body 2212 is connected in an arc-shaped transition. The first partition member 221 may be provided as a bottom plate protruding from the turntable lower housing 220, thereby leaving a gap between the bottom surface of the turntable 200 and the bottom plate of the turntable lower housing 220, forming a second airflow passage and a fourth airflow passage. By setting the first partition member 221 in a V-shape, the first turntable accommodating area is divided into a dehumidification area and a regeneration area, and the dehumidification area and the regeneration area are divided into a fan shape. Therefore, during the rotation of the turntable 200, the turntable 200 passes through the dehumidification area and the regeneration area repeatedly, and moisture adsorption and desorption can be continuously performed. This allows the turntable 200 to always have good moisture absorption capacity, improving the efficiency and effectiveness of moisture absorption.

[0071] In some embodiments, a second partition member 211 is provided on the turntable upper housing 210 to divide the turntable upper housing 210 into a dehumidifying region and a regeneration module mounting region. The second partition member 211 and the first partition member 221 are provided opposite the turntable upper housing 210 and the turntable lower housing 220, respectively, and the turntable 200 is located between the second partition member 211 and the first partition member 221. The first partition member 221 and the second partition member 211 can achieve a dynamic sealing effect with the turntable 200 to prevent the humid circulating airflow discharged from the drum and the regeneration airflow from colliding with each other. As the turntable 200 rotates, it passes through the dehumidifying region and the regeneration region, allowing moisture adsorption and dehydration drying to be continuously performed. The turntable 200 always has good moisture absorption capacity, improving moisture absorption efficiency and effectiveness.

[0072] In some embodiments, a third first partition body may be provided on the turntable lower housing 220, and a third second partition body may be provided at a corresponding position on the turntable upper housing 210. When viewed from the rotation direction of the turntable 200, the third, first, and second partition bodies may be provided downstream of the regeneration area or upstream of the dehumidification area, dividing the entire turntable housing space into three spaces, respectively realizing the functions of moisture absorption and dehumidification, regeneration and desorption, and cooling. In this embodiment, the substantially fan-shaped area between the third first and second partition bodies and the regeneration area is a cooling area that realizes the cooling function of the turntable 200. This configuration has the following advantages: after the turntable 200 passes through the regeneration area and is heated and desorbs moisture, high residual heat is generated on the turntable 200. This high residual heat affects the moisture adsorption capacity of the turntable 200 after it enters the dehumidification area. Therefore, providing a cooling area between the regeneration area and the dehumidification area provides a buffer cooling effect for the turntable 200 and improves moisture absorption efficiency.

[0073] In some embodiments, the drying module may include a housing, which includes a turntable accommodating cavity, a circulation fan accommodating cavity, a condenser accommodating cavity, a regeneration module accommodating section, and a regeneration fan mounting section, and the drum air outlet, the circulation fan, and the turntable accommodating cavity are sequentially connected to the drum air inlet, so that the wet circulation airflow discharged from the drum is sucked into the bottom of the turntable accommodating cavity by the circulation fan, and the wet circulation airflow passes through the turntable 200 from bottom to top, which adsorbs moisture in the wet circulation airflow, turning the wet circulation airflow into a dry circulation airflow, and the dry circulation airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency. The regeneration module 30, the condenser 401 and the regeneration fan form a closed-loop circulation communication. The regeneration airflow is sucked into the regeneration module by the regeneration fan. The regeneration airflow is heated by the regeneration module 30 and passes through the turntable 200 from top to bottom. After being heated, the regeneration airflow desorbs the moisture adsorbed by the turntable 200 and carries the water vapor to the condenser for heat exchange. The water vapor in the regeneration airflow is cooled and becomes condensed water, which is discharged from the condenser. The dry, low-temperature regeneration airflow enters the regeneration fan for the next circulation.

[0074] The housing is provided with lap joints 51, which are spaced apart along the periphery of the housing and mount the entire drying module to the frame. The housing includes a lower housing 100, a turntable upper housing 210, a circulation module upper housing 111, and a condensation module upper housing 410. To minimize the overall size of the combined washer-drying machine, the drying module may be mounted on top of the drum of the combined washer-drying machine. The drying module is horizontally oriented, i.e., the rotation axes of the turntable 200, the circulation fan, and the regeneration fan are substantially parallel and substantially perpendicular to the rotation axis of the combined washer-drying machine's upper housing / drum. In this manner, the overall height of the combined washer-drying machine depends on the diameter of the drum and the thickness of the housing above the drum. The circulation fan, regeneration fan, condenser, etc. are all located above the drum, and the drum is a nearly horizontal cylinder, providing more vertical space above it for easy installation of components such as the circulation fan, regeneration fan, and condenser. The circulation fan in the embodiments of the present application includes a circulation motor and an impeller, and the circulation motor drives the impeller to rotate, thereby changing the flow direction of the airflow and providing power to the wet circulation airflow.

[0075] In some embodiments, the lower housing may be molded as a single unit, facilitating installation of the entire drying module. By mounting the drying module on top of the drum of an integrated washer-dryer, vibrations from the drum can be prevented from affecting the entire drying module. Lower housing 100 includes circulation module lower housing 112, turntable lower housing 220, condensation module lower housing 420, and regenerative fan mounting section 320, and the lower housing may be molded as a single unit. Because the entire regenerative fan mechanism in this embodiment is commercially available, only regenerative fan mounting section 320 is provided. A first turntable receiving area may be provided in turntable lower housing 220. In an exemplary embodiment, turntable lower housing 220 includes a bottom plate and a circumferential sidewall protruding from the bottom plate, and the recessed portion is the first turntable receiving area. Similarly, a second turntable accommodating area may be provided in the turntable upper housing 210. The recess structures of the turntable upper housing 210 and the turntable lower housing 220 are symmetrically arranged. When the turntable upper housing 210 and the turntable lower housing 220 are mated together, the first and second turntable accommodating areas form a turntable accommodating cavity, allowing air to pass through the turntable accommodating cavity, thereby sealing the turntable upper housing 210 and the turntable lower housing 220. For example, a groove may be provided in the turntable upper housing 210 or the turntable lower housing 220, and a sealing strip may be provided in the groove to achieve sealing when the turntable upper housing 210 and the turntable lower housing 220 are mated together. The circulation module lower housing 112 and the circulation module upper housing 111 may be mated together to form a circulation fan accommodating cavity, and the condenser module lower housing 420 and the condenser module upper housing 410 may be mated together to form a condenser accommodating cavity.

[0076] In some embodiments, the drying module specifically includes: a housing having a turntable member accommodating cavity; a turntable member mounted in the turntable member accommodating cavity; the turntable member including a turntable 200; at least a portion of the turntable 200 being used to adsorb moisture in the humid circulating airflow; two side surfaces of the turntable 200 being spaced apart by a first inner wall and a second inner wall of the housing, respectively, forming an airflow passage; the first inner wall and the second inner wall being opposed to each other, and the first inner wall or the second inner wall being substantially parallel to the two side surfaces of the turntable 200; and at least one airflow diverting member 222 being disposed around at least one of the first inner wall or the second inner wall, the airflow diverting member 222 diverting the airflow entering the airflow passage. In some embodiments, the turntable member includes the turntable 200 and a drive assembly; the drive assembly may include a motor; and the motor drives the turntable 200 to rotate. The turntable 200 may be made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The wet circulating airflow entering the airflow passage on one side of the turntable 200 passes through the turntable 200 and reaches the airflow passage on the other side. The turntable 200 absorbs moisture in the wet circulating airflow, converting it into a dry circulating airflow. The circulating fan air outlet and the turntable member receiving cavity are connected substantially tangentially to the turntable, and the circulating airflow has a constant flow rate. Because the wet circulating airflow has a high moisture content, it escapes away from the center of rotation of the turntable under the action of centrifugal force. The airflow is usually formed at the large diameter part of the turntable 200, and the airflow becomes smaller in areas closer to the center of rotation of the turntable. As a result, the main moisture absorption area of ​​the turntable 200 is at the large diameter part, which affects the moisture absorption efficiency and the moisture absorption utilization rate of the turntable.In this regard, by providing the diverting member 222 around the bottom wall of the housing, the humid circulating airflow flowing into the airflow passage is diverted, with a portion entering an area close to the center of the circle and another portion entering an area close to the outer periphery of the turntable 200. As a result, the humid circulating airflow flowing into the airflow passage is more dispersed and more uniform, and the airflow comes into contact with the turntable 200 over a larger area, thereby improving the moisture absorption efficiency of the turntable 200.

[0077] In some embodiments, the housing includes a turntable lower housing 220 having a first turntable receiving area and a turntable upper housing 210 having a second turntable receiving area, the turntable upper housing and the turntable lower housing being matingly connected, the first turntable receiving area and the second turntable receiving area forming a turntable member receiving cavity, a gap is formed between the top surface of the turntable 200 and a partial inner top wall of the turntable upper housing 210 to form a first airflow passage, a gap is formed between the bottom surface of the turntable 200 and a partial bottom wall of the turntable lower housing to form a second airflow passage, the second airflow passage communicates with the drum air outlet, and the first airflow passage communicates with the drum air inlet, and the humid circulating airflow inside the drum passes through the turntable 200 via the second airflow passage and reaches the first airflow passage, and for example, the air diverting member 222 is provided around the bottom wall of the turntable lower housing 220 to divert the airflow flowing into the second airflow passage. For example, the wet circulating airflow discharged from the drum enters the bottom of the turntable member receiving cavity, i.e., diffuses within the second airflow passage. When the diverting member 222 is installed around the inner bottom wall of the turntable lower housing, it first diverges the incoming wet circulating airflow, with a portion entering the area close to the center and another portion entering the area close to the outer periphery of the turntable 200. This makes the wet circulating airflow entering the airflow passage more dispersed and uniform. As the wet circulating airflow passes through the turntable 200 from bottom to top, the turntable 200 absorbs the moisture in the wet circulating airflow, turning it into a dry circulating airflow, improving the moisture absorption efficiency of the turntable 200. The dry circulating airflow then passes through the first airflow passage and enters the drum through the drum air inlet, making full contact with the clothes, improving drying efficiency and reducing energy consumption.

[0078] In some embodiments, the at least one diversion member 222 may be provided in a dehumidification area of ​​the first turntable accommodating area, dividing the dehumidification area into at least a first diversion area and a second diversion area, a second air inlet 223 may be provided on a side wall of the turntable lower housing 220, one end of the diversion member 222 may be abutted against the second air inlet 223, dividing the second air inlet 223 into at least a first sub-port and a second sub-port, the first sub-port may be connected to the first diversion area, and the second sub-port may be connected to the second diversion area, etc. The diverting member 222 divides the second air inlet 223 into a first sub-port and a second sub-port, and in this way, the diverting member 222 divides the moist circulating airflow at the second air inlet 223 into two diverting areas near the center and the periphery, namely, the first diverting area and the second diverting area, thereby rationally dividing the moist circulating airflow and making the moist circulating airflow entering the first airflow passage more dispersed and uniform, and allowing the airflow to contact the turntable 200 over a larger area, thereby improving the moisture absorption efficiency of the turntable 200. Note that two or more diverting members 222 may be provided in the dehumidifying area of ​​the first turntable accommodating area, and they may be arranged in parallel to divide the dehumidifying area into multiple diverting areas.

[0079] In some embodiments, to prevent the airflow diverting member 222 from interfering with the turntable 200 during the rotation of the turntable 200, a preferred solution is for the airflow diverting member 222 to protrude from the bottom wall of the turntable lower housing 220 and limit the height of the airflow diverting member 222 so as not to come into contact with the turntable 200, thereby avoiding interference and forming an airflow seal between at least two diverted areas. Because the airflow diverting member 222 protrudes from the bottom wall of the turntable lower housing 220, a gap is formed between the bottom surface of the turntable 200 and the bottom wall of the turntable lower housing 220, i.e., the second airflow passage is divided into a first diverted area and a second diverted area.

[0080] In some embodiments, the first partition member 221 is disposed along the radial direction of the turntable lower housing 220, and the dehumidifying area and the regeneration area are substantially fan-shaped. The area of ​​the dehumidifying area may be set to 1.5 to 4 times the area of ​​the regeneration area. The area of ​​the dehumidifying area may be larger than the area of ​​the regeneration area, so that most of the turntable 200 is located in the dehumidifying area, further improving the moisture absorption efficiency and moisture absorption effect of the turntable 200. A dynamic sealing effect is achieved between the first partition member 221 and the turntable 200 to prevent the humid circulating airflow discharged from the drum from colliding with the regeneration airflow. Of course, a sealing member, such as a flexible sealing member, may be disposed between the first partition member 221 and / or the second partition member 211 and the turntable. The sealing member may be fixedly disposed on one of the first partition member 221 and / or the second partition member 211. When the turntable 200 rotates in the regeneration area, the regeneration airflow heats that part of the turntable 200, causing the moisture in that part to quickly desorb and be carried to the condenser by the regeneration airflow, so that the turntable 200 always has good water absorption ability, and the moisture absorption efficiency and effect are improved.

[0081] In some embodiments, the first partition member 221 includes at least a first partition body 2211 and a second partition body 2212, the first partition body 2211 and the second partition body 2212 are arranged along the radial direction of the turntable lower housing 220, one end of the first partition body 2211 and the second partition body 2212 are all connected to the inner side wall of the turntable lower housing 220, the other ends of the first partition body 2211 and the second partition body 2212 intersect in the central region of the turntable lower housing 220, the first partition member 221 is substantially V-shaped, and the intersection of the first partition body 2211 and the second partition body 2212 is connected in an arc-like transition. The first partition member 221 is a bottom plate protruding from the turntable lower housing 220, and there is a gap between the bottom surface of the turntable 200 and the bottom plate of the turntable lower housing 220, forming a second airflow passage. The V-shaped first partition member 221 divides the first turntable housing area into a dehumidification area and a regeneration area, which are fan-shaped. This allows the turntable 200 to pass through the dehumidification and regeneration areas repeatedly during rotation, continuously adsorbing and desorbing moisture. This ensures that the turntable 200 always has good moisture absorption capabilities and improves moisture absorption efficiency and effectiveness. The intersection of the first partition body 2211 and the second partition body 2212 is connected by an arc, which can better guide the circulating moist airflow after separation. A fixed shaft 224 protruding upward is provided at the intersection of the first partition body 2211 and the second partition body 2212, i.e., in the central region of the turntable lower housing 220. The center of the turntable 200 is attached to the fixed shaft 224, allowing the turntable 200 to rotate around the fixed shaft 224.

[0082] In some embodiments, the first diversion area is formed by the inner curved sidewall of the diversion member 222 and the first partition member 221, and the second diversion area is formed by the outer curved sidewall of the diversion member 222 and the inner wall of the turntable lower housing 220. The airflow dividing member 222 is located between the first partition member 221 and the inner wall of the turntable lower housing 220 and surrounds the bottom wall of the turntable lower housing 220, thereby allowing the moist circulating airflow entering the second airflow passage to be more in line with the fluid flow direction. The airflow quickly flows from the circulation fan air outlet into the second airflow passage and then, under the action of centrifugal force, diffuses along the side wall of the airflow dividing member 222 and the inner wall of the turntable lower housing 220 to the other end opposite the air inlet 223. This ensures that the airflow comes into contact with the turntable 200 for a longer period of time, rather than passing through the turntable 200 from bottom to top at the air inlet 223 and then directly entering the first airflow passage. This is advantageous for absorbing moisture from the moist circulating airflow, further improving the moisture absorption efficiency and effectiveness of the turntable 200.

[0083] In some embodiments, the second air inlet 223 is located near the first partition body 2211, the air diverting member 222 includes a first air diverter 2221 and a second air diverter 2222 smoothly connected to one end of the first air diverter 2221, the first air diverter 2221 and the first partition body 2211 are spaced apart, the other end of the second air diverter 2222 is connected to the second partition body, and the second air diverter 2222 is arc-shaped and parallel to the inner wall of the lower housing. After the moist circulating airflow enters through the second air inlet 223, the guiding of the first air diverter 2221 and the second air diverter 2222, combined with the action of centrifugal force, effectively diverges the moist circulating airflow and further promotes the diffusion of the moist circulating airflow within the second airflow passage. Of course, the flow diverting member 222 may be a unitary member parallel to the lower housing inner wall.

[0084] In some embodiments, the second air divider 2222 is arranged coaxially with the side wall of the turntable lower housing 220. The second air divider 2222 is arranged in an arc shape, and the center of the arc of the second air divider 2222 is arranged concentrically with the center of the arc of the side wall of the turntable lower housing 220, i.e., concentrically with the rotation center of the turntable 200, which is more suitable for fluid dynamics design and can better guide the moist circulating airflow after it enters through the second air inlet 223. Preferably, the second air divider 2222 may be arranged at 1 / 2 of the radius of the side wall of the turntable lower housing 220 to effectively and uniformly divide the incoming moist circulating airflow.

[0085] In some embodiments, the number of the airflow dividing members 222 may be two or more, and the second airflow passage may be divided into a plurality of airflow dividing regions, either uniformly or non-uniformly, to further reduce the effect of centrifugal force on the adsorption of moisture from the airflow. The specific structure may be the same as or similar to the above-described embodiments.

[0086] In some embodiments, the drying module specifically includes a circulation module 10 and a dehumidifying module 20. The circulation module 10 has a first circulation passage that communicates with the drum air outlet and allows the wet circulating airflow in the drum to enter the first circulation passage. The dehumidifying module 20 is located downstream of the circulation module 10 and has a second circulation passage that communicates with the drum air inlet. The drum air outlet, the first circulation passage, and the second circulation passage communicate with the drum air inlet in sequence to form a circulation passage. The dehumidifying module 20 includes a turntable member, at least a portion of which is located in the second circulation passage and is used to adsorb moisture in the wet circulating airflow from the drum. The wet circulating airflow in the drum passes through the first circulation passage and the second circulation passage in sequence to become a dry circulating airflow. The circulation module 10 includes a circulation fan, which provides power to the wet circulation airflow and contributes to air circulation. The circulation fan's air inlet is connected to the drum air outlet, and the circulation fan's air outlet is connected to the second circulation passage. A turntable member is installed in the second circulation passage. The turntable member first adsorbs moisture in the wet circulation airflow from the drum, turning the wet circulation airflow into a relatively dry circulation airflow. The dry circulation airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption.

[0087] In some embodiments, the dehumidification module 20 further includes a turntable lower housing 220 having a first turntable receiving area and a turntable upper housing 210 having a second turntable receiving area, the turntable upper housing 210 and the turntable lower housing 220 being matingly connected, the first turntable receiving area and the second turntable receiving area forming a turntable member receiving cavity, the turntable member being mounted in the turntable member receiving cavity, and the turntable member being mounted on the turntable. a drum air inlet, and a drive assembly for driving the turntable 200. The drum air inlet includes a drum 200, and the drive assembly may further include a drive assembly including a motor for driving the turntable 200 to rotate. The turntable 200 may be made of a material with good moisture absorption and desorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The wet circulating airflow discharged from the drum enters the bottom of the turntable receiving cavity and diffuses within the second airflow passage. The wet circulating airflow passes through the turntable 200 from bottom to top. The turntable 200 absorbs moisture from the wet circulating airflow, transforming it into a dry circulating airflow. The dry circulating airflow then enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. In the embodiment of the present application, the turntable 200 absorbs moisture from the wet circulating airflow, thereby avoiding the reduction in the moisture absorption capacity of the wet air caused by the use of an evaporator.

[0088] In some embodiments, the circulation module 10 includes a circulation module housing having an impeller accommodating cavity and provided with a first air inlet 102 and a first air outlet 103; an impeller 110 provided in the impeller accommodating cavity, the impeller rotation axis of which is substantially parallel to the first air inlet axis and the impeller rotation axis of which is substantially perpendicular to the first air outlet axis; and a circulation motor 120 fixedly connected to the circulation module housing and whose output shaft is fixedly connected to the impeller 110, wherein the first air inlet 102, the impeller accommodating cavity and the first air outlet 103 form a first circulation passage, wherein the first air inlet 102 communicates with the drum air outlet and the first air outlet 103 communicates with a second circulation passage, and the moist circulation airflow in the drum sequentially enters the first circulation passage and the second circulation passage. The rotation axis of the impeller 110 corresponds to the first air inlet, that is, the rotation axis of the impeller 110 can pass through the first air inlet 102, so that the impeller 110 can drive the airflow at the first air inlet 102 head-on and make the airflow enter the circulation module housing, and the airflow can be quickly sucked into the circulation module housing without increasing the rotation speed of the impeller 110. When the impeller 110 is driven to rotate by the circulation motor 120, centrifugal force is generated along the outer periphery of the impeller 110, and the airflow inside the impeller 110 flows in the direction of the centrifugal force. At this time, the airflow is scattered around the impeller 110, resulting in a change in the flow direction of the airflow, and a negative pressure is generated around the rotation axis of the impeller 110 and its vicinity, which can increase the airflow sucked into the first air inlet 102. Therefore, by designing the circulation power so that the circulation motor 120 controls the impeller 110 to rotate and create negative pressure, it is possible to prevent large wind forces from directly impinging on other components and causing damage. While conventional fans incur large losses when changing the airflow direction, the circulation module provided by the embodiment of the present application provides power for changing the airflow direction, allowing for greater flexibility in arranging the circulation module. In the embodiment of the present application, the circulation fan includes the circulation motor 120 and the impeller 110 that is driven to rotate by the circulation motor 120.

[0089] In some embodiments, the drying module further includes a pre-condenser disposed in the circulation passage, the pre-condenser being located upstream of the circulation module 10, and the pre-condenser being used to pre-dehumidify the humid circulation airflow from the drum. In order for the turntable 200 to have a better moisture absorption effect, the pre-condenser is disposed upstream of the circulation module 10 to reduce the humidity of the humid circulation airflow from the drum.

[0090] In some embodiments, the pre-condenser is a second condenser.

[0091] In some embodiments, the front condenser includes a water-cooled condenser or an air condenser, and the front condenser is provided in an air outlet passage communicating with the drum air outlet. The air outlet passage communicating with the drum air outlet may be provided at the left rear or right rear of the drum. For example, if the front condenser is a water-cooled condenser, the front condenser may be provided upstream of the filter assembly in the airflow direction, thereby reducing the humidity of the airflow entering the dehumidification module 20 while allowing some of the lint contained in the airflow to be directly carried by the condensed water, thereby reducing the frequency of cleaning the filter assembly. The water-cooled condenser installed in the drum air outlet passage may be a nozzle installed in the water inlet, which slowly sprays cooling water onto the outer wall of the pipe, maintaining a continuous low temperature on the pipe wall and condensing the wet circulating airflow through the pipe. The drum air outlet passage may be configured with a two-layer pipe wall, which may include an inner pipe and an outer pipe coaxially spaced apart. The wet circulating airflow passes through the inner pipe, forming a water flow space between the inner pipe and the outer pipe, guiding the cooling water into the drum outer casing or the washing machine outlet pipe. If the front condenser is an air condenser, the wet circulating airflow from the drum is cooled by heat exchange with the air condenser, and the water vapor in the wet circulating airflow is cooled and turned into condensed water, which is discharged through the air condenser's drain.

[0092] In some embodiments, the drying module further includes an auxiliary heater disposed in the circulation passage, the auxiliary heater being located downstream of the dehumidifying module 20, and used to heat the dry circulation airflow. The wet circulation airflow from the drum passes through the turntable 200 to adsorb moisture, and the wet circulation airflow becomes a dry circulation airflow. The auxiliary heater heats the dry circulation airflow, thereby increasing the temperature of the dry circulation airflow entering the drum and accelerating the drying speed of the clothes in the drum.

[0093] In some embodiments, the auxiliary heater is a second heater.

[0094] In some embodiments, a first partition member 221 is provided within the first turntable accommodating area to divide the first turntable accommodating area into a dehumidification area and a regeneration area, and a second air inlet 223 is provided on a side wall of the turntable lower housing 220, which is connected to the first air outlet 103 and the dehumidification area of ​​the second airflow passage. Specifically, a gap is provided between the bottom surface of the turntable 200 and the bottom wall of the dehumidification area of ​​the turntable lower housing, forming a second airflow passage. During operation, the portion of the turntable 200 in the dehumidification area can adsorb moisture in the humid circulating airflow entering the second airflow passage. During the rotation of the turntable 200, the portion that adsorbed moisture in the dehumidification area rotates to the regeneration area and is dehydrated and regenerated.

[0095] In some embodiments, a second air outlet is provided on the side wall of the turntable upper housing 210, and the second air outlet is connected to the dehumidifying region of the first airflow passage and the drum air inlet, respectively. The second air inlet 223 is located near one of the first and second partition bodies, and the second air outlet is located near the other of the first and second partition bodies. The second air inlet 223 and the second air outlet are provided on both sides of the first and second partition bodies, so that the humid circulating airflow from the drum enters the second airflow passage through the second air inlet 223 and is guided by the dehumidifying region to diffuse within the second airflow passage. The humid circulating airflow passes from bottom to top through the turntable 200 to reach the first airflow passage and converges at the second air outlet on the other side of the dehumidifying region, relatively lengthening the flow path of the circulating airflow. As a result, the contact area between the circulating airflow and the bottom and top surfaces of the turntable 200 is larger, and the utilization rate of the turntable 200 is improved.

[0096] In some embodiments, the drying module includes an air outlet passage 203 located at the second air outlet and protruding from the outside of the sidewall of the turntable upper housing 210, and a drum inlet air duct 52 with one end communicating with the air outlet passage and the other end communicating with the drum air inlet. The auxiliary heater includes a heating tube or heating wire and is located in the drum inlet air duct. A sealing ring may be provided between the drum inlet air duct 52 and the air outlet passage 203, and a pair of connecting flanges may be provided at the ends of the drum inlet air duct 52 and the air outlet passage 203, and the drum inlet air duct 52 is fixedly connected to the air outlet passage 203 by bolt connection, with the intermediate sealing ring being pressed and deformed to achieve a sealing effect. The auxiliary heater includes a heating tube or heating wire, and the heating tube or heating wire is provided along the inner wall of the drum inlet air duct 52. A heat insulating material may be provided between the heating tube or heating wire and the inner wall of the drum inlet air duct 52.

[0097] The circulation process of the wet circulating air from the drum will be described in detail below with reference to the accompanying drawings.

[0098] Referring to FIG. 11, the circulation module 10 and the dehumidification module 20 form a circulation passage. The flow direction of the moist circulation airflow from the drum is shown by the arrows in FIG. 11: the moist circulation airflow passes from the drum through the drum air outlet and the air outlet passage, in which a filter net and a front condenser are provided. After being pre-dehumidified, the moist circulation airflow enters the corrugated hose 50 (arrow 1), passes through the first air inlet 102, and enters the underside of the turntable 200 (arrow 2) under the power provided by the circulation fan, i.e., the second airflow passage. The wet circulating airflow diffuses within the turntable 200, passes through the turntable 200 from below, and reaches the upper side of the turntable 200 (arrow 3). The turntable 200 absorbs moisture from the wet circulating airflow, turning it into a dry circulating airflow, which then flows through the space above the turntable 200 (arrow 4), i.e., reaches the drum inlet air duct 52 via the first air flow passage (arrow 5). An auxiliary heater is provided in the drum inlet air duct to heat the dry circulating airflow, and the heated dry circulating airflow passes through the drum inlet air duct 52 and is circulated to the drum (arrow 6).

[0099] In some embodiments, the drying module includes: a dehumidifying module (20) having a second circulation passage, the second circulation passage communicating with the drum air outlet, and the wet circulation airflow in the drum entering the second circulation passage; a dehumidifying module including a turntable member, at least a portion of which is disposed in the second circulation passage and which is used to adsorb moisture in the wet circulation airflow from the drum; and a circulation module (10) located downstream of the dehumidifying module (20) having a first circulation passage, the first circulation passage communicating with the drum air inlet, and the wet circulation airflow in the drum passing through the second circulation passage and the first circulation passage in sequence to become a dry circulation airflow which enters the drum for the next circulation; the drum air outlet, the second circulation passage, and the first circulation passage in sequence communicating with the drum air inlet to form a circulation passage.

[0100] In the above embodiment, the positions of the circulation module 10 and the dehumidifying module 20 may be interchanged, i.e., the humid circulating airflow in the drum may first enter the dehumidifying module 20 through the drum air outlet passage, and then pass through the circulation module 10 and the drum air inlet passage into the drum, thereby allowing the connection relationship between the air inlet and air outlet of each component to be adjusted appropriately.

[0101] An embodiment of the present application provides a circulation module 10. As shown in Figures 8 to 10, the circulation module 10 specifically includes a circulation module housing, an impeller 110, and a circulation motor 120. A first air inlet 102 and a first air outlet 103 are provided on the circulation module housing, the impeller 110 is provided within the circulation module housing, and the rotation axis of the impeller 110 is parallel to the axis of the first air inlet 102 and substantially perpendicular to the axis of the first air outlet 103, the circulation motor 120 is fixedly connected to the circulation module housing, and the output shaft of the circulation motor 120 is fixedly connected to the impeller 110. The rotation axis of the impeller 110 corresponds to the first air inlet, that is, the rotation axis of the impeller 110 passes through the first air inlet 102, so the impeller 110 drives the airflow at the first air inlet 102 head-on, causing the airflow to enter the circulation module housing, and can quickly suck the airflow into the circulation module housing without increasing the rotation speed of the impeller 110. When the impeller 110 is driven to rotate by the circulation motor 120, centrifugal force is generated along the outer periphery of the impeller 110, causing the airflow inside the impeller 110 to flow in the direction of the centrifugal force. At this time, since the airflow is scattered around the impeller 110, the flow direction of the airflow changes, and negative pressure is generated around the rotation axis of the impeller 110 and its vicinity, so that the airflow sucked into the first air inlet 102 can be increased. Therefore, by designing the circulation power so that the circulation motor 120 rotates the impeller 110 to create negative pressure, it is possible to effectively prevent strong wind force from directly impinging on and damaging other components. In conventional fans, changes in airflow direction result in high losses, but the circulation module provided by the embodiments of the present application provides power for changes in airflow direction, providing more flexibility in arranging the circulation module.

[0102] In an alternative embodiment, the circulation module housing includes a circulation module lower housing 112 having a recessed first impeller accommodating area and a circulation module upper housing 111 having a recessed second impeller accommodating area, the circulation module lower housing 112 and the circulation module upper housing 111 being matingly connected, and the first impeller accommodating area and the second impeller accommodating area form an impeller accommodating cavity. The impeller 110 is located in the impeller accommodating cavity, which may be circular and larger in shape than the outer diameter of the impeller 110. The axis of the impeller accommodating cavity is parallel to the rotation axis of the impeller 110, so that the airflow output by the rotation of the impeller 110 is guided out by the inner walls of the circulation module lower housing 112 and the circulation module upper housing 111.

[0103] In an optional embodiment, the circulation module lower housing 112 includes a first bottom plate 1122 and a first side wall 1121, the first side wall protruding from the first bottom plate and arranged along the circumferential direction of the first bottom plate 1122, forming the first impeller accommodating area, a first groove being formed at the top of the first side wall 1121, and a sealing gasket 113 being provided in the first groove, the circulation module upper housing 111 includes a first top plate 1112 and a second side wall 1111, the second side wall protruding from the first top plate and arranged along the circumferential direction of the first top plate 1112, forming the second impeller accommodating area, a first protrusion being formed at the top of the second side wall 1111, the first protrusion and the first groove being engaged with each other, and when the circulation module lower housing 112 and the circulation module upper housing 111 are connected, the first protrusion abuts against the sealing gasket 113. The circulation module lower housing 112 may be formed by bending the bottom plate upward, and similarly, the circulation module upper housing 111 may be formed by bending the top plate downward. When the circulation module lower housing 112 and the circulation module upper housing 111 are assembled, the first protrusion presses the sealing gasket 113 in the first groove, deforming the sealing gasket 113 and achieving excellent sealing effect between the circulation module lower housing 112 and the circulation module upper housing 111.

[0104] In an alternative embodiment, the impeller 110 includes an impeller body 1101 and a fixed ring 1103 axially opposed to the impeller body 1101, the impeller body 1101 extending toward the fixed ring 1103 and having an accommodating cavity for accommodating a circulation motor, one end of the circulation motor 120 being arranged in the accommodating cavity, the output shaft of the circulation motor 120 being fixedly connected to the bottom of the impeller body 1101, and further including blades 1102, both ends of which are fixedly connected to the impeller body 1101 and the fixed ring 1103, respectively, the blades 1102 being arranged at intervals around the impeller body 1101, and the blades 1102 being arranged inclined forward along the rotation direction of the impeller. The impeller body 1101 may include a top cover plate, and one end of the blades 1102 along the length direction is fixedly connected to the cover plate, so that the airflow sucked in from the bottom of the impeller is blocked by the cover plate and output in the radial direction of the impeller. The impeller body 1101 extends in the direction of the blades 1102, and a recessed housing cavity is provided within the impeller body 1101. One end of the circulation motor 120 is embedded in the housing cavity, reducing the axial length of the entire circulation fan and the overall mechanical length of the circulation fan. The blades 1102 are tilted forward along the rotation direction of the impeller, improving the air outlet efficiency of the impeller, contributing to improving the noise reduction effect of the fan and improving the energy efficiency of the fan.

[0105] In an alternative embodiment, the first top plate 1112 has a mounting hole 1114 and a positioning cam penetrating the top thereof, the mounting hole 1114 being adapted to accommodate a circulating motor, the positioning cams being spaced apart along the circumferential direction of the mounting hole 1114, and the positioning cams being inserted into the mounting seat of the circulating motor to secure the circulating motor to the first top plate 1112. The mounting seat is provided on the housing of the circulation motor, and the mounting seat is provided at one end of the housing of the circulation motor away from the output shaft. The mounting seat has a positioning hole that matches the positioning cam. The positioning hole does not have to be through. The mounting seat has a bolt hole that communicates with the positioning hole. The positioning cam has a threaded hole that is coaxial with and matches the bolt hole. The positioning cam is inserted into the positioning hole. A bolt passes through the bolt hole and is screwed into the threaded hole to fix the circulation motor to the first top plate 1112. The circulation motor is embedded in the mounting hole 1114 and protrudes downward. In this way, the mounting part of the circulation motor is located outside the upper housing 111 of the circulation module, making it easy to install and remove the circulation motor.

[0106] In an alternative embodiment, the circulation module housing is a worm-shell type, and has a contraction extending perpendicular to the rotation axis of the impeller 110, and the first air outlet communicates with the impeller accommodating cavity through the contraction. The circulation module housing is a worm-shell type, and the worm shell has a unique shape that allows the airflow to change direction after passing through the impeller 110 and exit through the contraction, preventing the airflow from constantly circulating within the impeller accommodating cavity, meeting fluid design requirements, and maximizing the air volume and speed required for the airflow.

[0107] In the exemplary embodiment, the first air inlet 102 is located on the first bottom plate 1122, and is coaxial with the mounting hole 1114. The contracted portion has an air outlet cavity, and the first air inlet 102, impeller accommodating cavity, and air outlet cavity are sequentially connected to the first air outlet, and the impeller accommodating cavity, air outlet cavity, and first air outlet are located on the same horizontal plane. The contracted portion has an air outlet cavity, and after passing through the impeller 110, the airflow changes direction and flows through the air outlet cavity to the first air outlet, and the air outlet cavity is substantially perpendicular to the rotation axis of the impeller 110. The impeller accommodating cavity, air outlet cavity, and first air outlet are located on substantially the same horizontal plane. This reduces the height of the circulation module housing, reduces the space occupied by the entire circulation module, and also reduces the overall height and volume of a combined washer-dryer machine equipped with the circulation module.

[0108] In an alternative embodiment, the circulation module 10 may further include a circulating air interface member connected to the contraction section. Alternatively, the circulating air interface member and the circulation module housing may be integrally formed. The side of the circulating air interface member away from the contraction section is arc-shaped, and the circulating air interface member gradually expands toward the side away from the contraction section. The circulating air interface member has an expansion air duct, both ends of which communicate with the air outlet cavity and the first air outlet, respectively. The circulating air interface member may also be configured as two separate housings, upper and lower, connected to the circulation module upper housing 111 and the circulation module lower housing 112, respectively. The cross-sectional area of ​​the expansion air duct gradually increases toward the side away from the contraction section. After passing through the impeller 110, the airflow enters the air outlet cavity and the expansion air duct, where the kinetic pressure energy of the airflow is further converted into static pressure energy, improving the kinetic pressure energy conversion ability and the operating performance of the fan.

[0109] In an alternative embodiment, lower housing connecting members 1123 are provided on the first side wall 1121, the lower housing connecting members 1123 are provided at intervals along the outer periphery of the first side wall 1121 and protrude from the first side wall 1121, and upper housing connecting members 1113 are provided on the second side wall 1111, the installation positions of the upper housing connecting members 1113 correspond one-to-one to the lower housing connecting members 1123, and the upper housing connecting members 1113 are connected to the lower housing connecting members 1123, thereby fixing the positions of the circulation module lower housing 112 and the circulation module upper housing 111 relative to each other. Both the upper housing connecting member 1113 and the lower housing connecting member 1123 are provided with corresponding bolt through-holes, and bolts are inserted into the bolt through-holes, thereby realizing a detachable connection between the circulation module lower housing 112 and the circulation module upper housing 111.

[0110] In an alternative embodiment, the circulation module housing is provided with a fixing clip 1115, which is used to fix wires or conduits and to properly position the electrical wires of the circulation motor, or wires and conduits such as water and gas pipelines on the entire machine.

[0111] In an alternative embodiment, the circulation module further includes a transition member 130, which is provided in the circulation module lower housing 112, the transition member 130 is fitted to the first impeller accommodating area, the transition member is fixedly connected to the first bottom plate 1122, a through hole is provided through the transition member, the through hole is connected to the first impeller accommodating area, and the side of the transition member away from the first impeller accommodating area is connected to the corrugated hose 50, and the corrugated hose 50 is docked with the air inlet of the lower housing via the transition member 130. The transition piece has first and second transition holes, which are uniformly spaced apart along the circumferential direction of the through hole, the diameter of the first air inlet 102 is smaller than the distribution diameter of the first transition holes, threaded holes corresponding to the ends of the corrugated hose 50 are provided, and bolts pass through the first transition holes and are screwed into the threaded holes to secure the corrugated hose 50 to the transition piece 130, the distribution diameter of the second transition holes is larger than the diameter of the first air inlet 102, and the first base plate 1122 has threaded holes corresponding to the second transition holes, and bolts pass through the second transition holes and are embedded in the threaded holes to secure the transition piece 130 to the first base plate 1122.

When installing the corrugated hose 50, the corrugated hose 50 can be first secured to the transition piece 130, and then the transition piece 130 can be secured to the first bottom plate 1122, facilitating the installation and removal of the corrugated hose 50.

[0112] In some embodiments, as shown in FIGS. 1 and 12 to 17, the drying module includes a circulation module 10, a dehumidifying module 20, and a regeneration module 30. The circulation module 10 has a first circulation passage that communicates with the drum air outlet and allows the moist circulating airflow in the drum to enter the first circulation passage. The dehumidifying module has a second circulation passage that is located downstream or upstream of the circulation module. The drum air outlet communicates with the first circulation passage, and the second circulation passage communicates with the drum air inlet, forming a circulation passage. The dehumidifying module includes a moisture-absorbing and dehumidifying member, at least a portion of which is disposed in the second circulation passage and is used to adsorb moisture in the moist circulating airflow from the drum. The regeneration module 30 further includes a regeneration member that is disposed adjacent to at least another portion of the moisture-absorbing and dehumidifying member and at least a portion of which is discharged. The circulation module 10 may include a circulation fan, which provides power to the wet circulation airflow and contributes to air circulation. The circulation fan's air inlet communicates with the drum air outlet, which communicates with the second circulation passage. A moisture-absorbing and dehumidifying member is installed in the second circulation passage. The moisture-absorbing and dehumidifying member first absorbs moisture in the wet circulation airflow from the drum, turning the wet circulation airflow into a relatively dry circulation airflow. The dry circulation airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. To enable repeated use of the moisture-absorbing and dehumidifying member, a regenerating member is used to remove the moisture adsorbed by the moisture-absorbing and dehumidifying member. The regenerating member may be, for example, a heating member or an ultrasonic member, and removes the moisture adsorbed by the moisture-absorbing and dehumidifying member by heating or ultrasonic dehumidification.

[0113] In one embodiment, proximity may be adjacent, or a gap or distance may be maintained between the devices, and as will be apparent to those skilled in the art, the regenerating member may be located upstream of the moisture absorbing and dehumidifying member.

[0114] In some embodiments, the dehumidifying module is located upstream of the circulation module, the second circulation passage communicates with the drum air outlet, the moisture absorbing and dehumidifying member first adsorbs moisture in the humid circulation airflow from the drum, the first circulation passage communicates with the drum air inlet, and the relatively dry circulation airflow from the first circulation passage enters the drum, and the drum air outlet, the second circulation passage, the first circulation passage and the drum air inlet are sequentially communicated to form a circulation passage.

[0115] In some embodiments, the moisture absorbing and dehumidifying member includes a turntable 200, the regeneration member is a heating member, and the regeneration module has a regeneration passage, with the heating member and at least a portion of the turntable being sequentially arranged at a bubbly point on the regeneration passage, and the regeneration airflow in the regeneration passage partially passes through the heating member and at least a portion of the turntable sequentially, resulting in a high-temperature and humid regeneration airflow. Specifically, the moisture absorbing and dehumidifying member includes a turntable 200 and a drive assembly, with the drive assembly including a motor that drives the turntable 200 to rotate. The turntable 200 may be made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The heating element is provided in the regeneration passage, and for example, the heating element may include a heater, so that the regeneration airflow in the regeneration passage becomes a high-temperature regeneration airflow after being heated by the heater, and the high-temperature regeneration airflow passes through the portion of the turntable 200 in the regeneration passage in order to more efficiently dehydrate the turntable. In this way, when the turntable 200 rotates in the regeneration passage during the rotation process, the adsorbed moisture is continuously desorbed, and the turntable 200 can be used repeatedly.

[0116] In some embodiments, the drying module further includes a turntable upper housing 210 and a turntable lower housing 220, which are matingly connected to form a turntable accommodating cavity, and the turntable 200 is mounted in the turntable accommodating cavity, with a gap between the top surface of the turntable 200 and a portion of the inner wall of the turntable upper housing forming a first airflow passage, a gap between the bottom surface of the turntable 200 and a portion of the inner wall of the lower housing forming a second airflow passage, the second airflow passage communicating with the drum air outlet, and the first airflow passage communicating with the drum air inlet, such that the wet circulating airflow in the drum passes through the second airflow passage from bottom to top through the turntable 200 to reach the first airflow passage, thereby forming a dry circulating airflow. Here, the second airflow passage, the turntable 200, and the first airflow passage form a second circulating passage.

[0117] In some embodiments, the regeneration passage is relatively isolated from the circulation passage, and the regeneration airflow and the wet circulation airflow do not communicate with each other. Because a portion of the turntable 200 is in the regeneration passage and another portion is in the circulation passage, the turntable 200 alternately passes through the regeneration passage and the circulation passage during continuous rotation. In an exemplary embodiment, when a portion of the turntable 200 rotates in the regeneration passage, the high-temperature regeneration airflow passes through the turntable 200 from top to bottom, effectively dehydrating the turntable. When another portion of the turntable 200 rotates in the circulation passage, the wet circulation airflow passes through the turntable 200 from bottom to top, allowing the turntable 200 to fully absorb moisture in the wet circulation airflow. The regeneration airflow and the wet circulation airflow simultaneously act on the turntable 200. To maintain smooth rotation of the turntable 200, the regeneration airflow and the wet circulation airflow can be configured to flow in opposite directions. By providing partition members and sealing members on the turntable upper housing 210 and the turntable lower housing 220, a dynamic sealing effect is achieved during the rotation of the turntable 200, preventing the humid circulating airflow and the regenerating airflow from colliding with each other. As the turntable 200 rotates, moisture absorption and dehydration drying can be carried out continuously, so that the turntable 200 always has good moisture absorption ability, improving the efficiency and effectiveness of moisture absorption.

[0118] In some embodiments, the regeneration module further includes a regeneration fan 301, which is located in the regeneration passage and upstream of the heating element. The regeneration fan 301 provides power to the regeneration airflow, improving circulation and efficiency.

[0119] In some embodiments, the drying module further comprises a condensing module 40, specifically a condenser 401. The condenser 401 is disposed in the regeneration passage between the turntable 200 and the regeneration fan 301, with the condenser located downstream of the turntable 200 and upstream of the regeneration fan 301. This allows the hot and humid regeneration airflow in the regeneration passage to enter the condenser 401, become a dry and low-temperature regeneration airflow, and then enter the regeneration fan 301, forming a closed-loop circulation. When the turntable 200 rotates in the regeneration passage, the regeneration airflow heats that portion of the turntable 200, and the moisture in that portion is quickly evaporated and desorbed and carried away by the regeneration airflow. At this time, the regeneration airflow becomes a hot and humid regeneration airflow and enters the condenser 401, so that the turntable 200 always has good moisture absorption capacity, further improving the moisture absorption efficiency and effect of the turntable 200. In an exemplary embodiment, the high-temperature and humid regenerated airflow enters the condenser 401 for heat exchange and cooling, the water vapor in the regenerated airflow is cooled to become condensed water, and the cooled airflow is discharged from the condenser 401, and the dry, low-temperature regenerated airflow enters the regenerated fan 301 for the next circulation. In an alternative embodiment, the high-temperature and humid regenerated airflow enters the condenser 401 for heat exchange and cooling, the water vapor in the regenerated airflow is cooled to become condensed water, and the cooled airflow is discharged from the condenser 401, and the dry, low-temperature regenerated airflow is discharged to the atmosphere through the air outlet of the condenser 401, so that the regenerated airflow can form an open circulation to avoid adversely affecting the atmospheric temperature and humidity in the space where the combined washer-dryer washing machine is located.

[0120] In some embodiments, the regeneration module further includes a regeneration module upper housing 310 having a heating element accommodating cavity, the heating element being mounted in the heating element accommodating cavity, the heating element being located upstream of the turntable, the heating element accommodating cavity being in communication with the turntable, and the heating element being used to heat the regeneration airflow and at least partially evaporate moisture adsorbed by the turntable 200. Specifically, the regeneration module upper housing 310 includes a heating element accommodating cavity formed by protruding from a top wall and a side wall surrounding the top wall, and a base protruding outward along the side wall, the base having mounting holes through which the base is fixedly connected to the turntable upper housing 210.

[0121] In some embodiments, to more uniformly heat the incoming regeneration airflow and more uniformly dehydrate and dry the turntable 200, a preferred solution is to include an air equalizing member and heater in a stacked heating element configuration, with the heater located on the air equalizing member and the turntable 200, and the regeneration airflow entering the heating element-accommodating cavity and passing sequentially through the air equalizing member, heater, and turntable 200.

[0122] In some embodiments, the regeneration module upper housing 310 has a fan-shaped structure, and a heater air inlet 311 is provided on the outer curved side of the regeneration module upper housing 310. A gap exists between the air equalizing member and the top wall of the regeneration module upper housing 310, forming a third airflow passage. A gap exists between the bottom surface of the turntable 200 and the inner wall of the regeneration area of ​​the turntable lower housing 220, forming a fourth airflow passage. The third airflow passage communicates with the heater air inlet 311. The regeneration airflow enters the third airflow passage through the heater air inlet, passes through the air equalizing member and heater, passes from top to bottom through the turntable, and reaches the fourth airflow passage, becoming a high-temperature and humid regeneration airflow. The regeneration airflow enters the third airflow passage through the heater air inlet 311. The air equalizing member ensures that the regeneration airflow comes into uniform contact with the heater. The uniformly heated regeneration airflow partially dehydrates and dries the turntable 200 in the regeneration area.

[0123] Condenser module 40 specifically further includes condenser module upper housing 410 and condenser module lower housing 420, which are mated together to form a condenser accommodating cavity, and condenser 401 is installed in the condenser accommodating cavity. The arrows in Figure 4 indicate the flow direction of the regenerated airflow, which passes from top to bottom through the turntable and reaches the fourth airflow passage, becoming a high-temperature and humid regenerated airflow which then flows into condenser module lower housing 420 and enters condenser 401 for heat exchange and cooling.

[0124] In some embodiments, the drying module further includes a first connecting member 3013, both ends of which communicate with the condenser and the regenerative fan, respectively, through which the regenerative airflow enters the regenerative fan 301 via the condenser 401, and a second connecting member 3014, both ends of which communicate with the regenerative fan and the heater air inlet, respectively, through which the regenerative airflow enters the third airflow passage via the regenerative fan. Because the condenser 401 and the regenerative fan 301 are close to each other, a rigid pipe connector as shown in Figures 5 and 6 can be used, which not only supports the regenerative fan 301 but also makes the overall structure of the drying module compact and reduces the space it occupies. Of course, the first connecting member 3013 can also be a flexible member and can be docked to the two rigid structures of the condenser and the regenerative fan air inlet.

[0125] In some embodiments, the regeneration module may further include a regeneration fan mounting part 320, which specifically includes an upper regeneration fan housing 321 and a lower regeneration fan housing 322, which together form a regeneration fan accommodating cavity. The lower regeneration fan housing 322 and the first connecting member 3013 are fixedly connected via a flange to firmly support the regeneration fan 301. The first connecting member 3013 is flexible, and one end of the first connecting member 3013 can be deformed to fit into the opening of the lower regeneration fan housing 322, providing a good seal due to its flexibility.

[0126] In some embodiments, the first connecting member 3013 has a first air inlet and a first air outlet, the first air inlet is adapted to communicate with the condenser air outlet, and the first air outlet is adapted to communicate with the regeneration fan air inlet, the first air inlet is a substantially rectangular opening, the first air outlet is a substantially circular opening, and the plane on which the first air inlet is located is set to be substantially perpendicular to the plane on which the first air outlet is located, thereby changing the flow direction of the regeneration airflow. A rectangular connecting flange or a flexible boundary is provided on the first air inlet end surface of the first connecting member 3013, which may be deformed to enter the condenser air outlet, and is fixedly connected to the condensing module upper housing 410 and the condensing module lower housing 420. The housing structure of the first connecting member 3013 is irregular, and the cross section of the air duct in the first connecting member 3013 gradually transitions from rectangular to circular from the first air inlet to the first air outlet, allowing the first connecting member 3013 to smoothly guide air.

[0127] In some embodiments, the second connecting member 3014 has a second air inlet and a second air outlet, the second air inlet is adapted to communicate with the regeneration fan air outlet, the second air outlet is adapted to communicate with the heater air inlet, the second air inlet is a substantially rectangular opening, the second air outlet is a circular-arc opening, the plane on which the second air inlet is located is substantially parallel to the plane on which the second air outlet is located, and the area of ​​the second air outlet is larger than that of the second air inlet. The air duct in the second connecting member 3014 gradually expands from the second air inlet to the second air outlet, so that the kinetic pressure energy of the airflow can be further converted into static pressure energy, which enhances the kinetic pressure energy conversion ability, improves the operating performance of the fan, and minimizes the formation of turbulence.

[0128] In some embodiments, the regeneration member is an ultrasonic member, which includes an ultrasonic generator. When the ultrasonic generator is operated, ultrasonic energy is generated, causing the turntable 200 to vibrate at a high frequency, which continuously breaks down the water film and air film on the outer surface of the turntable 200, thereby increasing the heat and mass exchange coefficient between the turntable 200 and the regeneration airflow. Through the heat and mass exchange, the moisture adsorbed by the turntable 200 is carried by the regeneration airflow, which can improve the regeneration efficiency of the turntable 200 at low temperatures.

[0129] In some embodiments, the drying module further includes a turntable upper housing 210, which includes a substantially fan-shaped regeneration module receiving section. The regeneration module 30 is attached to the regeneration module receiving section and positioned above the turntable 200. The regeneration module is used, for example, to heat the regeneration airflow to desorb moisture adsorbed by the turntable 200. An airflow space is provided inside the regeneration module, forming a third airflow passage. A gap is provided between a portion of the bottom surface of the turntable 200 and the inner wall of the regeneration region of the turntable lower housing 220, forming a fourth airflow passage. The regeneration module further includes a heater for heating the regeneration airflow. The heated regeneration air passes through the turntable 200 from top to bottom via the third airflow passage and reaches the fourth airflow passage, dehydrating a portion of the turntable 200 in the regeneration region. During the rotation of the turntable 200, the regeneration air passes through the dehumidification region and the regeneration region, repeating a cycle of moisture adsorption and desorption.

[0130] In an exemplary embodiment, a first turntable accommodating area is provided in the turntable lower housing 220, which includes a bottom plate and a circumferential sidewall protruding from the bottom plate, and the recessed portion is the first turntable accommodating area. Similarly, a second turntable accommodating area is provided in the turntable upper housing 210, which includes at least a dehumidifying area but not a regenerating area, and a regenerating module accommodating portion is provided on the radial edge of the second turntable accommodating area. The second turntable accommodating area and a portion of the first turntable accommodating area form at least the dehumidifying area, and the regenerating module accommodating portion and the other portion of the first turntable accommodating area form the regenerating area. Airflow passes through the turntable accommodating cavity, and the turntable upper housing 210 and the turntable lower housing 220 are sealed together. For example, a groove or a flange is provided on the turntable upper housing 210 or the turntable lower housing 220, respectively, and a sealing strip is provided in the groove. When the turntable upper housing 210 and the turntable lower housing 220 are engaged and connected, the flange presses the sealing strip in the groove to achieve sealing.

[0131] In some embodiments, the drying module further includes a turntable lower housing 220, which includes a first turntable receiving area and a first partition member 221 disposed within the first turntable receiving area to divide the first turntable receiving area into a dehumidification area and a regeneration area, with the air outlet of the circulation fan communicating with the dehumidification area. A gap is formed between the bottom surface of the turntable 200 and the bottom wall of the dehumidification area of ​​the turntable lower housing, forming a second airflow passage. When the turntable 200 is operating, the portion in the dehumidification area can adsorb moisture in the humid circulating airflow entering the second airflow passage. During the rotation of the turntable 200, the portion that adsorbed moisture in the dehumidification area rotates to the regeneration area and undergoes dehydration regeneration.

[0132] An embodiment of the present application provides a regeneration module 30, which includes, as shown in FIGS. 7-9 , a regeneration module upper housing 310 having a heating element-accommodating cavity, and a heating element mounted in the heating element-accommodating cavity and positioned above a turntable, the heating element-accommodating cavity communicating with the turntable, and used to heat the regeneration airflow and desorb moisture adsorbed by the turntable. In some embodiments, the turntable member includes a turntable 200 and a drive assembly, the drive assembly including a motor, and the motor drives the turntable 200 to rotate. The turntable 200 is formed from a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The wet circulating airflow discharged from the drum enters the bottom of the turntable accommodating cavity, and the wet circulating airflow in the dehumidifying region passes from bottom to top through the turntable 200. The turntable 200 absorbs moisture in the wet circulating airflow, turning it into a dry circulating airflow. The dry circulating airflow enters the drum through the drum air inlet and comes into full contact with the clothes, improving drying efficiency and reducing energy consumption. The regenerating element includes a heater used to heat the regenerating airflow. The heated regenerating airflow passes from top to bottom through the heating element accommodating cavity through the turntable 200, dehydrating and drying the part of the turntable 200 in the regenerating region. As the turntable 200 rotates, it passes through the dehumidifying region and the regenerating region, repeating the moisture adsorption and desorption processes. In this way, the dry circulating airflow continuously enters the drum and comes into full contact with the clothes, improving drying efficiency and reducing energy consumption.

[0133] Specifically, the playback module upper housing 310 includes a first top wall 312 and a third side wall 313 protruding from the periphery of the first top wall 312 to form a heating element accommodating cavity, and a base 314 protruding outward from the third side wall 313, with mounting holes provided in the base 314 and fixedly connected to the turntable upper housing 210 through the mounting holes.

[0134] In some embodiments, to more uniformly heat the incoming regeneration airflow and more uniformly dehydrate and dry the turntable 200, a preferred solution is to include an air equalizing element and heater in a stacked arrangement of heating elements, with the heater located on the air equalizing element and the turntable 200, and the regeneration airflow entering the heating element receiving cavity and passing sequentially through the air equalizing element, heater, and turntable 200.

[0135] In some embodiments, the regeneration module upper housing 310 has a fan-shaped structure, and the heater air inlet 311 is provided on the outer curved side of the regeneration module upper housing 310. In the embodiments of the present application, a preferred solution is that the regeneration module upper housing 310 has a fan-shaped structure, and the regeneration module upper housing 310 may also have an irregular structure, and is not excessively limited here. The regeneration module upper housing 310 is matingly connected to the turntable upper housing 210, which separates the dehumidification area and the regeneration area, i.e., the humid circulating airflow in the dehumidification area and the regeneration airflow in the regeneration area can be maintained in a substantially isolated state.

[0136] In some embodiments, a gap exists between the air equalizing member and the top wall of the regeneration module upper housing 310, forming a third airflow passageway, which communicates with the heater air inlet 311. A gap exists between the bottom surface of the turntable 200 and the inner wall of the regeneration area of ​​the turntable lower housing 220, forming a fourth airflow passageway. The regeneration airflow enters the third airflow passageway through the heater air inlet 311, and the air equalizing member allows the regeneration airflow to come into more uniform contact with the heater. The uniformly heated regeneration airflow desorbs moisture from the portion of the turntable 200 within the regeneration area.

[0137] In some embodiments, the air equalizing member includes an air equalizing plate 330 and side plates protruding from the periphery of the air equalizing plate 330, the air equalizing plate 330 and side plates surrounding a heater-accommodating region, the heater being disposed within the heater-accommodating region, the air equalizing plate 330 being fan-shaped, and the air equalizing plate 330 being provided with air holes 331 spaced apart. The provision of the air holes allows the regenerative airflow to more uniformly enter the heater below.

[0138] In some embodiments, the heater includes a plurality of end-to-end connected heating tubes 340, the heating tubes 340 being spaced apart along the radial direction of the fan, and the lengths of the heating tubes 340 being substantially perpendicular to the radial direction of the fan. The heating tubes 340 are distributed in an S-shape, allowing for a longer distribution of the heating tubes 340 in the heater-accommodating area, increasing the contact area with the regeneration airflow and resulting in more efficient heat exchange with the regeneration airflow.

[0139] In some embodiments, the air holes are arranged in rows, the locations of the air holes in each row substantially corresponding to the locations of the heater tubes 340, and the diameters of the air holes tend to decrease along the radial direction of the sector from the outer arc toward the center. The heater air inlet 311 is located on the outer curved side of the regeneration module upper housing 310, and the diameters of the air holes near the heater air inlet 311 are relatively large, while the diameters of the air holes away from the heater air inlet 311 are relatively small.

[0140] In some embodiments, the heating tubes 340 are positioned below the air holes, and the axes of the heating tubes 340 are offset from the centerlines of the corresponding rows of air holes, such that the centerlines of the air holes in each row are closer to the heater air inlets 311 than the axes of the heating tubes 340. The heating tubes 340 are positioned below the air holes, and the heating tubes 340 are positioned near the air equalizing plate 330 or the air equalizing plate 330, so that the heating tubes 340 are fixed to the air equalizing plate 330 with pipe clamps without creating significant resistance to the regeneration airflow passing through the air holes, and a certain gap is left between the heating tubes 340 and the air equalizing plate 330 for the regeneration airflow to pass through. The regeneration airflow is blown from the heater air inlets 311 and blows inward along the radial direction of the fan, generating velocity along the flow direction of the regeneration airflow. Therefore, by slightly offsetting the centerlines of the air holes in each row, the regeneration airflow passing through the air holes can be made to directly face the heating tubes 340, thereby achieving higher heat exchange efficiency between the regeneration airflow and the heating tubes 340.

[0141] In some embodiments, the regeneration module upper housing 310 has a fan-shaped structure, and the heater air inlet 311 is provided on the side wall of the regeneration module upper housing 310, and the side wall is provided along the radial direction of the fan, where the direction of the regeneration airflow entering the heating element accommodating cavity is set to be opposite to the rotation direction of the turntable 200. That is, the regeneration airflow is blown from the fan-shaped regeneration module into the heater accommodating space in a direction substantially perpendicular to the radius along or opposite to the rotation direction of the turntable, so that the airflow is more uniformly heated by the heater.

[0142] In some embodiments, the heater includes a plurality of heating tubes 340 connected end to end, the heating tubes 340 are spaced apart along the radial direction of the fan, and the length of the heating tubes 340 is set parallel to the side wall facing the heater air inlet 311. Of course, the heating tubes 340 may be arranged substantially along the radial direction of the heating film set, and in this case, the air inlet direction perpendicular to the radial direction can be adopted to achieve a more uniform air flow and heating effect.

[0143] In some embodiments, the regeneration module is mounted in the second space, the second space further comprising a thermally conductive member 350 communicating with the heater-accommodating region and a temperature detection module used to detect the temperature of the heater-accommodating region. The temperature detection module is mounted in the third space, the third space being a space covered by the thermally conductive member 350 and physically isolated from the second space via the thermally conductive member 350. The regeneration airflow is heated by the heater in the heater-accommodating region to become a high-temperature regeneration airflow. The second space is in communication with the heater-accommodating region, and the high-temperature regeneration airflow diffuses in the second space. Therefore, the temperature in the heater-accommodating region can be determined by detecting the temperature in the second space. The temperature detection module is mounted in the third space, the thermally conductive member 350 covers the temperature detection module, and the thermally conductive member 350 transfers the heat received from the second space to the air in the third space. The temperature detection module detects the temperature of the air in the third space, thereby detecting the temperature of the regeneration airflow in the heater-accommodating region communicating with the second space. The thermal conduction member 350 is made of a metal material that easily conducts heat, such as copper or aluminum. The thermal conduction member 350 receives the heat of the high-temperature regeneration airflow in the second space and transfers the heat to the temperature detection module in the third space, thereby making the heat conduction uniform, making the temperature detected by the temperature detection module tend to be stable, and improving the accuracy of the detection results. When the temperature detection module directly detects the regeneration airflow in the heater accommodating area, the regeneration airflow in the heater accommodating area may have turbulent or / turbulent flow conditions, which can avoid frequent fluctuations in the detection results.

[0144] The base 314 extends outward away from the heater accommodating area, and a groove is provided on at least a portion of the bottom surface of the base 314, forming a second space. The thermally conductive member 350 is mounted in the groove, and the thermally conductive member 350 covers the temperature detection module. The base 314 has a first side edge, which extends along the radial direction of the fan, and the groove is located on the first side edge. Of course, for more accurate detection, a similar groove may be provided on a second side edge opposite the first side edge, and the temperature detection module may be located therein. The groove is located on the first side edge and communicates with the heater accommodating area. The heated high-temperature regeneration airflow diffuses into the groove, and the thermally conductive member 350 receives heat and conducts the heat to the temperature detection module. This prevents the temperature detection module from being directly blown by the regeneration airflow flowing through the heater accommodating area, thereby reducing fluctuations in detection results due to turbulence.

[0145] The upper housing 310 of the regeneration module is provided with a mounting base 318, which is fixedly connected to the first side edge and located on the other side edge away from the groove of the first side edge. The mounting base 318 has a through-hole formed therein, forming a substantially hexahedral shape with one side open. The temperature detection module is mounted within the mounting hole, and a thermally conductive member 350 covers the opening of the mounting hole seat 318 to form a third space, which is adapted to the temperature detection module. Specifically, the temperature detection module is mounted within the mounting hole and covered by the thermally conductive member 350, isolating the temperature detection module from the second space and preventing leakage of the regeneration airflow. The mounting base 318 may be provided with a fixing member, which is used to fix an electrical cable connected to the temperature detection module.

[0146] Furthermore, the heat conduction member 350 contacts the contact points of the temperature detection module. Turbulence / disturbances may occur in the regeneration airflow flowing through the heater-accommodating area, causing the regeneration airflow temperature to become unstable within a local area. To prevent this, the heat conduction member 350 may optionally be provided with a protruding rib structure on its side facing the second space to increase the contact area with the high-temperature regeneration airflow, extend the conduction path, and ensure that the temperature conducted to the temperature detection module is a stable average value. The heat conduction member 350 may be provided as a heat conduction sheet that is easy to mold and covers the temperature detection module. For example, the heat conduction member 350 may be provided with a protrusion on its side facing the second space and a corresponding recess on its other side, with the temperature detection module embedded in the recess, and the contact points of the temperature detection module contact the recess. The protrusion increases the contact area between the heat conduction member 350 and the regeneration airflow.

[0147] In some embodiments, the surface of the heat conduction member 350 may have a heat-resistant and corrosion-resistant layer to extend the service life of the heat conduction member 350 and prevent the heat conduction member 350 from rusting in a high-temperature and humid environment.

[0148] The regeneration module provided by the embodiment of the present application will be described in detail below in relation to the flow direction of the regeneration airflow.

[0149] As shown in FIGS. 1 to 7 , the drying module includes a circulation module 10 and a dehumidifying module 20. The circulation module 10 has a first circulation passage that communicates with the drum air outlet and allows the wet circulating airflow in the drum to enter the first circulation passage. The dehumidifying module 20 is located downstream of the circulation module 10 and has a second circulation passage that communicates with the drum air inlet. The drum air outlet, the first circulation passage, the second circulation passage, and the drum air inlet are sequentially connected to form a circulation passage. The dehumidifying module 20 includes a turntable member, at least a portion of which is located on the second circulation passage. The turntable member is used to adsorb moisture in the wet circulating airflow from the drum. The wet circulating airflow in the drum passes through the first circulation passage and the second circulation passage sequentially to become a dry circulating airflow. The circulation module 10 includes a circulation fan, which provides power to the wet circulation airflow and contributes to air circulation. The circulation fan's air inlet is connected to the drum air outlet, and the circulation fan's air outlet is connected to the second circulation passage. A turntable member is installed in the second circulation passage. The turntable member first adsorbs moisture in the wet circulation airflow from the drum, turning the wet circulation airflow into a relatively dry circulation airflow. The dry circulation airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption.

[0150] A second aspect of the present application provides a drying module, comprising: a dehumidifying module having a second circulation passage, the second circulation passage communicating with a drum air outlet, and causing the moist circulation airflow in the drum to enter the second circulation passage; the dehumidifying module including a turntable member, at least a portion of which is disposed in the second circulation passage, the turntable member being used to adsorb moisture in the moist circulation airflow from the drum; and a circulation module located downstream of the dehumidifying module, having a first circulation passage, the first circulation passage communicating with the drum air inlet, the moist circulation airflow in the drum passing through the second circulation passage and the first circulation passage in sequence to become a dry circulation airflow which enters the drum for the next circulation; the drum air outlet, the second circulation passage, the first circulation passage and the drum air inlet being sequentially communicated to form the circulation passage.

[0151] In the above embodiment, the positions of the circulation module 10 and the dehumidifying module 20 may be interchanged, i.e., the humid circulating airflow in the drum may first enter the dehumidifying module 20 through the drum air outlet passage, and then pass through the circulation module 10 and the drum air inlet passage to enter the drum. This allows the connection relationship between the air inlet and air outlet of each component to be adaptively adjusted.

[0152] A third aspect of the present application provides a combined washing and drying washing machine including the drying module described above.

[0153] The washing and drying combination washing machine further comprises a drum, which is provided with a drum air inlet and a drum air outlet, the drum air inlet and the drum air outlet being respectively located at both ends of the drum rotation shaft, so that the high-temperature dry airflow entering the drum can fully exchange heat with the clothes inside the drum, the drum air inlet being located at the front or rear, the drum air outlet being located at the rear or front, and the drum air inlet and the drum air outlet being respectively connected to the space between the outer and inner drum cylinders, for example, the drum air inlet and the drum air outlet being respectively located at both ends of the drum rotation shaft, so that the airflow can fully contact the clothes inside the drum and improve drying efficiency.

[0154] Of course, the specific locations of the drum air inlet and air outlet are not specifically limited by this disclosure and may be located at the same end of the drum or may be offset on the drum.

[0155] In some embodiments, the drying module specifically includes the following: a housing provided in a turntable member accommodating cavity; a turntable member mounted in the turntable member accommodating cavity; the turntable member including a turntable 200; at least a portion of the turntable 200 used to adsorb moisture in the humid circulating airflow; gaps formed between two side surfaces of the turntable 200 and a first inner wall and a second inner wall of the housing, respectively, to form an airflow passage; the first inner wall and the second inner wall are opposed to each other, and the first inner wall or the second inner wall is substantially parallel to the two side surfaces of the turntable 200; and at least one airflow diverting member 222 provided around at least one of the first inner wall or the second inner wall, the airflow diverting member 222 used to divert the airflow entering the airflow passage. In some embodiments, the turntable member includes the turntable 200 and a drive assembly, the drive assembly including a motor, and the motor can be driven to rotate the turntable 200. The turntable 200 is made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The wet circulating airflow entering the airflow passage on the turntable 200 side passes through the turntable 200 and reaches the airflow passage on the other side. The turntable 200 absorbs moisture in the wet circulating airflow, converting it into a dry circulating airflow. Because the circulation fan air outlet and the turntable member receiving cavity are connected substantially tangentially to the turntable, the circulating airflow has a constant flow rate. Because the wet circulating airflow has a high moisture content, it escapes away from the center of rotation of the turntable under the action of centrifugal force. The airflow is usually located at the large diameter part of the turntable 200, and the airflow is smaller in areas closer to the center of rotation of the turntable. As a result, the main moisture absorption areas of the turntable 200 are concentrated at the large diameter part, which affects the moisture absorption efficiency and moisture absorption utilization rate of the turntable.In contrast, by providing the diverting member 222 around the bottom wall of the housing, the moist circulating airflow flowing into the airflow passage is diverted so that a portion of it enters an area close to the center of the circle and another portion enters an area close to the outer periphery of the turntable 200, making the moist circulating airflow flowing into the airflow passage more dispersed and more uniform, allowing the airflow to come into contact with the turntable 200 over a larger area and improving the moisture absorption efficiency of the turntable 200.

[0156] In some embodiments, the housing includes a turntable lower housing 220 having a first turntable receiving area and a turntable upper housing 210 having a second turntable receiving area, the turntable upper housing and the turntable lower housing being matingly connected, the first turntable receiving area and the second turntable receiving area forming a turntable member receiving cavity, a gap between the top surface of the turntable 200 and a partial inner top wall of the turntable upper housing 210 forming a first airflow passage, a gap between the bottom surface of the turntable 200 and a partial bottom wall of the turntable lower housing forming a second airflow passage, the second airflow passage communicating with the drum air outlet, the first airflow passage communicating with the drum air inlet, the humid circulating airflow inside the drum passing through the turntable 200 through the second airflow passage and reaching the first airflow passage, and illustratively, the air diverting member 222 is provided around the bottom wall of the turntable lower housing 220 to divert the airflow flowing into the second airflow passage. For example, when the wet circulating airflow discharged from the drum enters the bottom of the turntable member receiving cavity, i.e., diffuses within the second airflow passage, and the diverting member 222 is installed around the inner bottom wall of the lower housing of the turntable, the incoming wet circulating airflow can be diverted, with a portion entering an area close to the center of the turntable and another portion entering an area close to the outer periphery of the turntable 200, making the wet circulating airflow entering the airflow passage more dispersed and uniform. As the wet circulating airflow passes through the turntable 200 from bottom to top, the turntable 200 absorbs the moisture in the wet circulating airflow, turning it into a dry circulating airflow, thereby improving the moisture absorption efficiency of the turntable 200. The dry circulating airflow flows from the first airflow passage to the drum air inlet and enters the drum, where it comes into full contact with the clothes, improving drying efficiency and reducing energy consumption.

[0157] In some embodiments, the at least one diversion member 222 is provided in a dehumidification area of ​​the first turntable accommodating area, dividing the dehumidification area into at least a first diversion area and a second diversion area, a second air inlet 223 is provided on a side wall of the turntable lower housing 220, one end of the diversion member 222 abuts against the second air inlet 223, dividing the second air inlet 223 into at least a first sub-port and a second sub-port, the first sub-port communicates with the first diversion area, and the second sub-port communicates with the second diversion area, etc. The diverting member 222 divides the second air inlet 223 into a first sub-port and a second sub-port, and thus the diverting member 222 divides the moist circulating airflow at the second air inlet 223 into two diverting areas near the center and the periphery, namely the first diverting area and the second diverting area, thereby rationally diverting the moist circulating airflow, making the moist circulating airflow entering the first airflow passage more dispersed and uniform, and allowing the airflow to contact the turntable 200 over a larger area, thereby improving the moisture absorption efficiency of the turntable 200. Note that two or more diverting members 222 may be provided for the dehumidifying area of ​​the first turntable accommodating area, and they may be arranged in parallel to divide the dehumidifying area into multiple diverting areas.

[0158] An embodiment of the present application provides a circulation module 10, which, as shown in Figures 8 to 10, specifically includes a circulation module housing, an impeller 110, and a circulation motor 120. The circulation module housing is provided with a first air inlet 102 and a first air outlet 103, the impeller 110 is provided within the circulation module housing, the rotation axis of the impeller 110 is parallel to the axis of the first air inlet 102 and is substantially perpendicular to the axis of the first air outlet 103, the circulation motor 120 is fixedly connected to the circulation module housing, and the output shaft of the circulation motor 120 is fixedly connected to the impeller 110. The rotation axis of the impeller 110 corresponds to the first air inlet, i.e., the rotation axis of the impeller 110 is aligned with the first air inlet 102. Therefore, the impeller 110 drives the airflow at the first air inlet 102 directly, forcing the airflow into the circulation module housing and allowing the airflow to be quickly sucked into the circulation module housing without increasing the rotation speed of the impeller 110. When the impeller 110 is driven to rotate by the circulation motor 120, centrifugal force is generated along the outer periphery of the impeller 110, causing the airflow inside the impeller 110 to flow in the direction of the centrifugal force. At this time, the airflow is scattered around the impeller 110, changing its direction of flow, and negative pressure is generated around the rotation axis of the impeller 110 and its vicinity, increasing the airflow sucked into the first air inlet 102. Therefore, by designing the circulation power so that the circulation motor 120 controls the rotation of the impeller 110 to generate negative pressure, it is possible to effectively prevent strong wind force from directly impacting and damaging other components. While conventional fans cause high losses when changing the airflow direction, the circulation module provided by the embodiments of the present application provides power for changing the airflow direction, providing more flexibility in arranging the circulation module.

[0159] In an alternative embodiment, the circulation module housing includes a circulation module lower housing 112 having a recessed first impeller accommodating area and a circulation module upper housing 111 having a recessed second impeller accommodating area, the circulation module lower housing 112 and the circulation module upper housing 111 being matingly connected, and the first impeller accommodating area and the second impeller accommodating area form an impeller accommodating cavity. The impeller 110 is located in the impeller accommodating cavity, which has a circular shape larger than the outer diameter of the impeller 110. The axis of the impeller accommodating cavity is parallel to the rotation axis of the impeller 110, so that the airflow output by the rotation of the impeller 110 is guided and flows by the inner walls of the circulation module lower housing 112 and the circulation module upper housing 111.

[0160] In an optional embodiment, the circulation module lower housing 112 includes a first bottom plate 1122 and a first side wall 1121, the first side wall protruding from the first bottom plate and arranged along the circumferential direction of the first bottom plate 1122, forming the first impeller accommodating area, a first groove being formed at the top of the first side wall 1121, and a sealing gasket 113 being provided in the first groove, the circulation module upper housing 111 includes a first top plate 1112 and a second side wall 1111, the second side wall protruding from the first top plate and arranged along the circumferential direction of the first top plate 1112, forming the second impeller accommodating area, a first protrusion being formed at the top of the second side wall 1111, the first protrusion being engaged with the first groove, and the first protrusion abutting against the sealing gasket 113 when the circulation module lower housing 112 and the circulation module upper housing 111 are connected. The circulation module lower housing 112 may be formed by bending the bottom plate upward, and similarly, the circulation module upper housing 111 may be formed by bending the top plate downward. When the circulation module lower housing 112 and the circulation module upper housing 111 are assembled, the first protrusion presses the sealing gasket 113 in the first groove, deforming the sealing gasket 113 and achieving excellent sealing effect between the circulation module lower housing 112 and the circulation module upper housing 111.

[0161] In an alternative embodiment, the impeller 110 includes an impeller body 1101 and a fixed ring 1103 axially opposed to the impeller body 1101, the impeller body 1101 extending toward the fixed ring 1103 and having an accommodating cavity for accommodating a circulation motor, one end of the circulation motor 120 being provided in the accommodating cavity, the output shaft of the circulation motor 120 being fixedly connected to the bottom of the impeller body 1101, and the impeller 1101 including blades 1102, both ends of which are fixedly connected to the impeller body 1101 and the fixed ring 1103, respectively, the blades 1102 being spaced apart around the impeller body 1101, and the blades 1102 being inclined forward along the rotation direction of the impeller. The impeller body 1101 includes a top cover plate, and one longitudinal end of the blades 1102 is fixedly connected to the cover plate, so that the airflow sucked in from the bottom of the impeller is blocked by the cover plate and output in the radial direction of the impeller. The impeller body 1101 extends in the direction of the blades 1102, and a recessed accommodation cavity is provided within the impeller body 1101. One end of the circulation motor 120 is fitted into the accommodation cavity, reducing the overall axial length of the circulation fan and the overall mechanical length of the circulation fan. The blades 1102 are tilted forward along the rotation direction of the impeller, thereby improving the air outlet efficiency of the impeller, improving the noise reduction effect of the fan, and contributing to improving the energy efficiency of the fan.

[0162] In an alternative embodiment, the top of the first top plate 1112 has mounting holes 1114 and positioning cams extending therethrough, the mounting holes 1114 being adapted to accommodate a circulating motor, the positioning cams being spaced apart along the circumferential direction of the mounting holes 1114, and the positioning cams being inserted into mounting seats on the circulating motor to secure the circulating motor to the first top plate 1112. The mounting seat is provided on the housing of the circulation motor, and the mounting seat is provided at one end of the housing of the circulation motor away from the output shaft. The mounting seat has a positioning hole that matches the positioning cam. The positioning hole does not have to be through. The mounting seat has a bolt hole that communicates with the positioning hole. The positioning cam has a threaded hole that is coaxial with and matches the bolt hole. The positioning cam is inserted into the positioning hole, and a bolt passes through the bolt hole and is screwed into the threaded hole to fix the circulation motor to the first top plate 1112. The circulation motor is embedded in the mounting hole 1114 and protrudes downward. In this way, the mounting portion of the circulation motor is located outside the upper housing 111 of the circulation module, making it easy to install and remove the circulation motor.

[0163] In an alternative embodiment, the circulation module housing is a worm-shell type, and has a constriction extending along a direction perpendicular to the rotation axis of the impeller 110, and the first air outlet communicates with the impeller accommodating cavity through the constriction. The circulation module housing is a worm-shell type, and the worm shell has a unique shape, and after the airflow passes through the impeller 110, the flow direction changes and is output through the constriction, thereby preventing the airflow from constantly circulating within the impeller accommodating cavity, meeting fluid design requirements, and maximizing the air volume and air speed required for the airflow.

[0164] In the exemplary embodiment, the first air inlet 102 is located on the first bottom plate 1122, and is coaxial with the mounting hole 1114. The contracted portion has an air outlet cavity, and the first air inlet 102, impeller accommodating cavity, air outlet cavity, and first air outlet are sequentially connected, and the impeller accommodating cavity, air outlet cavity, and first air outlet are located on the same horizontal plane. The contracted portion has an air outlet cavity, and the airflow changes direction after passing through the impeller 110 and flows through the air outlet cavity to the first air outlet, and the air outlet cavity is substantially perpendicular to the rotation axis of the impeller 110, and the impeller accommodating cavity, air outlet cavity, and first air outlet are located on substantially the same horizontal plane. This reduces the height of the circulation module housing, reduces the space occupied by the entire circulation module, and also reduces the height and volume of the entire washing and drying machine equipped with the circulation module.

[0165] In an alternative embodiment, the circulation module 10 further includes a circulating air interface member, which may be connected to the contraction section, or may be integral with the circulation module housing. The side of the circulating air interface member away from the contraction section is arc-shaped, and the circulating air interface member gradually expands toward the side away from the contraction section. The circulating air interface member has an expansion air duct, both ends of which communicate with the air outlet cavity and the first air outlet, respectively. The circulating air interface member may be configured as two separate upper and lower housings, connected to the circulation module upper housing 111 and the circulation module lower housing 112, respectively. The cross-sectional area of ​​the expansion air duct gradually increases toward the side away from the contraction section. After passing through the impeller 110, the airflow enters the air outlet cavity and the expansion air duct, whereby the kinetic pressure energy of the airflow is further converted into static pressure energy, improving the kinetic pressure energy conversion ability and the operating performance of the fan.

[0166] In an alternative embodiment, lower housing connecting members 1123 are provided on the first side wall 1121, and the lower housing connecting members 1123 are provided at intervals along the outer periphery of the first side wall 1121 and protrude from the first side wall 1121. An upper housing connecting member 1113 is provided on the second side wall 1111, and the installation position of the upper housing connecting member 1113 corresponds one-to-one with the installation position of the lower housing connecting member 1123, and the upper housing connecting member 1113 is connected to the lower housing connecting member 1123 to fix the positions of the circulation module lower housing 112 and the circulation module upper housing 111 relative to each other. Bolt through holes that match the upper housing connecting member 1113 and the lower housing connecting member 1123 are provided, and bolts are inserted into the bolt through holes, thereby realizing a detachable connection between the circulation module lower housing 112 and the circulation module upper housing 111.

[0167] In an optional embodiment, the circulation module housing is provided with a fixing clip 1115, which is used to fix wiring or piping, allowing for better placement of the electrical wires of the circulation motor, or wiring and piping such as water and gas pipelines on the entire machine.

[0168] In an alternative embodiment, the circulation module further includes a transition member 130, which is provided in the circulation module lower housing 112, the transition member 130 is fitted to the first impeller accommodating area, the transition member is fixedly connected to the first bottom plate 1122, a through hole is provided through the transition member, the through hole is connected to the first impeller accommodating area, and the side of the transition member away from the first impeller accommodating area is connected to the corrugated hose 50, and the corrugated hose 50 is docked with the air inlet of the lower housing via the transition member 130. The transition piece has first and second transition holes, all of which are uniformly spaced apart along the circumferential direction of the through-hole. The diameter of the first air inlet 102 is smaller than the distributed diameter of the first transition holes. Threaded holes corresponding to the ends of the corrugated hose 50 are provided, and bolts are threaded through the first transition holes to secure the corrugated hose 50 to the transition piece 130. The distributed diameter of the second transition holes is larger than the diameter of the first air inlet 102. Threaded holes corresponding to the second transition holes are provided in the first base plate 1122, and bolts are threaded through the second transition holes to secure the transition piece 130 to the first base plate 1122.

[0169] 1 to 7 , the drying module includes: a housing having a turntable member accommodating cavity; a turntable member mounted in the turntable member accommodating cavity and including a turntable 200, at least a portion of which is used to adsorb moisture in a humid circulating airflow, two sides of which are respectively spaced apart from a first inner wall and a second inner wall of the housing to form an airflow passage, wherein the first inner wall faces the second inner wall and the first inner wall or the second inner wall is substantially parallel to the two sides of the turntable 200; and at least one airflow diverting member 222 provided around at least one of the first inner wall or the second inner wall and used to divert the airflow entering the airflow passage. In some embodiments, the turntable member includes the turntable 200 and a drive assembly, the drive assembly including a motor, and the motor can drive the rotation of the turntable 200. The turntable 200 is made of a material with good moisture absorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The wet circulating airflow entering the airflow passage on the turntable 200 side passes through the turntable 200 and reaches the airflow passage on the other side. The turntable 200 absorbs moisture in the wet circulating airflow, converting it into a dry circulating airflow. The circulating fan air outlet and the turntable member receiving cavity are connected substantially tangentially to the turntable. The circulating airflow has a constant flow rate. Because the wet circulating airflow has a high moisture content, it escapes away from the center of rotation of the turntable under the action of centrifugal force. The airflow is usually located at the large diameter part of the turntable 200, and the airflow is smaller in areas closer to the center of rotation of the turntable. This causes the main moisture absorption areas of the turntable 200 to be concentrated at the large diameter part, affecting the moisture absorption efficiency and the moisture absorption utilization rate of the turntable.In contrast, by installing the diverting member 222 around the bottom wall of the housing, the humid circulating airflow flowing into the airflow passage can be diverted, with part of it entering an area close to the center of the circle and the other part entering an area close to the outer periphery of the turntable 200, making the humid circulating airflow flowing into the airflow passage more dispersed and more uniform, and allowing the airflow to come into contact with the turntable 200 over a larger area, thereby improving the moisture absorption efficiency of the turntable 200.

[0170] In some embodiments, the housing includes a turntable lower housing 220 having a first turntable receiving area and a turntable upper housing 210 having a second turntable receiving area, the turntable upper housing and the turntable lower housing being matingly connected, the first turntable receiving area and the second turntable receiving area forming a turntable member receiving cavity, a gap between the top surface of the turntable 200 and a partial inner top wall of the turntable upper housing 210 forming a first airflow passage, a gap between the bottom surface of the turntable 200 and a partial bottom wall of the turntable lower housing forming a second airflow passage, the second airflow passage communicating with the drum air outlet, the first airflow passage communicating with the drum air inlet, the humid circulating airflow inside the drum passing through the turntable 200 via the second airflow passage and reaching the first airflow passage, and for example, the air diverting member 222 is provided around the bottom wall of the turntable lower housing 220 to divert the airflow flowing into the second airflow passage. For example, the wet circulating airflow discharged from the drum enters the bottom of the turntable member accommodating cavity, i.e., diffuses within the second airflow passage. When the diverting member 222 is installed around the inner bottom wall of the lower turntable housing, the incoming wet circulating airflow is first diverted, with a portion entering an area close to the center of the turntable and another portion entering an area close to the outer periphery of the turntable 200. This makes the wet circulating airflow entering the airflow passage more dispersed and uniform. As the wet circulating airflow passes through the turntable 200 from bottom to top, the turntable 200 absorbs the moisture in the wet circulating airflow, turning it into a dry circulating airflow, thereby improving the moisture absorption efficiency of the turntable 200. The dry circulating airflow enters the drum from the first airflow passage toward the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption.

[0171] The present disclosure does not limit the specific location of the turntable's air inlet, as long as the airflow enters through the turntable housing, passes through the turntable, and then exits the turntable housing. Therefore, the airflow can enter through the first airflow space between the turntable and the upper housing, pass through the turntable, and then exit through the second airflow space between the turntable and the lower housing. The circulation fan may be located upstream or downstream of the turntable, as long as it is designed and implemented according to the actual situation. The airflow dividing member 222 is located at a position corresponding to the turntable's airflow inlet, and may be located, for example, on the inner wall of the lower housing or, of course, on the inner wall of the upper housing.

[0172] In some embodiments, a first partition member 221 is provided within the first turntable accommodating area to divide at least the first turntable accommodating area into a dehumidification area and a regeneration area. A gap is formed between the bottom surface of the turntable 200 and the bottom wall of the dehumidification area of ​​the turntable lower housing, forming a second airflow passage. A portion of the turntable 200 is located above the dehumidification area and adsorbs moisture in the humid circulating airflow that has entered the second airflow passage. During the rotation of the turntable 200, some of the turntables that have adsorbed moisture rotate into the regeneration area and desorb moisture. Then, some of the turntables that have desorbed moisture continue to rotate into the dehumidification area and adsorb moisture, and this process may be repeated.

[0173] In an exemplary embodiment, the turntable lower housing 220 has a first turntable accommodating area, which includes a bottom plate and a circumferential sidewall protruding from the bottom plate, and the recessed portion is the first turntable accommodating area. Similarly, the turntable upper housing 210 has a second turntable accommodating area, which includes at least a dehumidifying area but not a regenerating area, and a regenerating module mounting portion is provided on the radial edge of the second turntable accommodating area. The second turntable accommodating area and a portion of the first turntable accommodating area form at least the dehumidifying area, and the regenerating module mounting portion and another portion of the first turntable accommodating area form the regenerating area. Because air flows through the turntable accommodating cavity, the turntable upper housing 210 and the turntable lower housing 220 can be sealed together. For example, the turntable upper housing 210 or the turntable lower housing 220 may have a groove or flange, and a sealing strip may be provided in the groove to engage and seal the turntable upper housing 210 and the turntable lower housing 220.

[0174] In some embodiments, the at least one diversion member 222 is provided in the dehumidification area of ​​the first turntable accommodating area, dividing the dehumidification area into at least a first diversion area and a second diversion area, a second air inlet 223 is provided on the side wall of the turntable lower housing 220, one end of the diversion member 222 abuts against the second air inlet 223, dividing the second air inlet 223 into at least a first sub-port and a second sub-port, the first sub-port communicates with the first diversion area, and the second sub-port communicates with the second diversion area. The diverting member 222 divides the second air inlet 223 into a first sub-port and a second sub-port, and thus the diverting member 222 divides the moist circulating airflow at the second air inlet 223 to enter two diverting areas near the center and the periphery, i.e., the first diverting area and the second diverting area, thereby rationally diverting the moist circulating airflow, making the moist circulating airflow entering the first airflow passage more dispersed and uniform, and allowing the airflow to contact the turntable 200 over a larger area, thereby improving the moisture absorption efficiency of the turntable 200. Note that two or more diverting members 222 may be provided for the dehumidifying area of ​​the first turntable accommodating area, and they may be arranged in parallel to divide the dehumidifying area into multiple diverting areas.

[0175] In some embodiments, the first partition member 221 is disposed radially on the turntable lower housing 220, forming a turntable mounting area at the center of the first turntable receiving area. Due to the substantially radially disposed first partition member 221, the dehumidification area and the regeneration area are substantially fan-shaped. Here, the area of ​​the dehumidification area may be set to be two to three times the area of ​​the regeneration area. The area of ​​the dehumidification area may be larger than the area of ​​the regeneration area, and most of the turntable 200 may be located in the dehumidification area, further improving the moisture absorption efficiency and moisture absorption effect of the turntable 200. A dynamic sealing effect may be achieved between the first partition member 221 and the turntable 200 to prevent the humid circulating airflow discharged from the drum from colliding with the regeneration airflow. When the turntable 200 rotates in the regeneration area, the regeneration airflow heats that portion of the turntable 200, rapidly evaporating and desorbing moisture from that portion and carrying it to the condenser. This allows the turntable 200 to always have good moisture absorption capacity, improving moisture absorption efficiency and effect.

[0176] In some embodiments, the drying module is located at the second air outlet and includes an air outlet passage 203 protruding from the outside of the side wall of the turntable upper housing 210, and a drum inlet air duct 52, one end of which communicates with the air outlet passage and the other end of which communicates with the drum air inlet. The auxiliary heater includes a heating tube or heating wire, and is located within the drum inlet air duct. A seal ring is located between the drum inlet air duct 52 and the air outlet passage 203, and a pair of connecting flanges are provided to fit the ends of the drum inlet air duct 52 and the air outlet passage 203. The drum inlet air duct 52 is fixedly connected to the air outlet passage 203 by bolts, and the intermediate seal ring is pressed and deformed to achieve a sealing effect. The auxiliary heater includes a heating tube or heating wire, and the heating tube or heating wire is located along the inner wall of the drum inlet air duct 52. A heat insulating material is located between the heating tube or heating wire and the inner wall of the drum inlet air duct 52.

An upper housing connecting member 1113 is provided on the second side wall 1111, and the installation position of the upper housing connecting member 1113 corresponds one-to-one with the installation position of the lower housing connecting member 1123. The upper housing connecting member 1113 is connected to the lower housing connecting member 1123 to fix the relative positions of the circulation module lower housing 112 and the circulation module upper housing 111. Matching bolt through-holes are provided on the upper housing connecting member 1113 and the lower housing connecting member 1123, and bolts are inserted into the bolt through-holes, thereby realizing a detachable connection between the circulation module lower housing 112 and the circulation module upper housing 111.

[0178] In an optional embodiment, the circulation module housing is provided with a fixing clip 1115, which is used to fix wiring or piping, allowing for better placement of the electrical wires of the circulation motor, or wiring and piping such as water and gas pipelines on the entire machine.

[0186] In some embodiments, since the temperature of the airflow passing through the first connecting member A is not high and the first connecting member A is assembled between the rigid condensing module 40 and the regenerative fan 301, the first connecting member A may be integrally molded from a flexible member, and have an external shape substantially as shown in Fig. 21.

During the installation process, the first air inlet 102 and the first air outlet 103 of the flexible first connecting member A are deformed and extend into the housing of the condensing module 40 and the air inlet housing of the regenerative fan 301, and then the deformation of the flexible first connecting member A is restored, and the first side A01 and the second outer mounting base A11 are respectively engaged in the air outlet of the housing of the condensing module 40 and the air inlet housing of the regenerative fan 301. Thereafter, the first side A01 and the second outer mounting base A11 are clamped between the pressing plate or hoop and the inner wall of the housing inside the housing of the condensing module 40 and the housing of the regenerative fan 301 through the pressing plate or hoop, thereby realizing the sealing and fastening installation of the flexible first connecting member A.

[0191] In some embodiments, as shown in Figures 21 and 26, the first connecting member A and the second connecting member B are irregularly shaped, making them difficult to manufacture in a single molding operation and potentially resulting in complex molds and difficult demolding. Therefore, in some embodiments of the present disclosure, a single member is divided into multiple members and processed for manufacturing. In some embodiments, welding methods include ultrasonic welding, friction welding, and hot melt welding. The first connecting body A2 and the second connecting body A4, and the third connecting body B2 and the fourth connecting body are welded using the above-mentioned connection methods to form two complete connecting members, and then the first connecting member A or the second connecting member B is attached to the desired position.

[0192] In some embodiments, as shown in Figures 30 to 32, the first connecting member A is sealed by a flat groove. For example, the first connecting body A2 and the second connecting body A4 may each have a countersunk groove and a protrusion.

[0195] The combined washing and drying washing machine according to the embodiment of the present application comprises a drum and a drying module, and the drying module comprises the regeneration circulation module according to any of the above embodiments.

[0196] In some embodiments, the first connecting member A or the second connecting member B is decomposed and subdivided by planar division.

[0197] In some embodiments, the first connecting member A or the second connecting member B is fixed by "2 holes + 2 holes + 2 holes."

[0198] As shown in FIG. 20 , in some embodiments, the embodiments of the present disclosure further provide a combined washer-dryer washing machine, which includes a drum and a drying module, and the drying module includes a moisture absorption passage, a dehumidification passage, and a moisture absorption and dehumidification member, and the dehumidification passage includes, but is not limited to, a fan, a regeneration mechanism (heater), and a condenser, and the fan and the regeneration mechanism, and the fan and the condenser are connected by a connecting member.

[0199] Example 1 The heater air inlet 311 is located on the outer curved side of the regeneration module upper housing 310, which has a fan-shaped structure. The regeneration airflow enters the third airflow passage along the radial direction of the heater air inlet 311, enters the heater accommodating area through the air holes on the air equalizing plate 330, and exchanges heat with the heating tube 340. The heated high-temperature regeneration airflow passes through the turntable 200 and dehydrates and dries part of the turntable 200 in the regeneration area. The diameter of the air holes tends to decrease along the radial direction of the fan from the outer arc toward the center. The heating tubes 340 are distributed in an S-shape, with the heating tubes 340 spaced apart along the radial direction of the fan. The length of the heating tubes 340 is perpendicular to the radial direction of the fan. The air holes on the air equalizing plate 330 are arranged corresponding to the heating tubes 340. Therefore, the diameter of the air holes near the heater air inlet 311 is relatively large, and the diameter of the air holes away from the heater air inlet 311 is relatively small. That is, the flow rate of the heated high-temperature regeneration airflow received by the turntable 200 within the regeneration area decreases uniformly or non-uniformly along the radial direction of the fan from the outer arc toward the center, allowing the turntable 200 to be heated and dried more uniformly.

[0200] Example 2 The second embodiment does not repeat the commonalities with the first embodiment, but differs from the first embodiment in the following points: The heater air inlet 311 is located on the side wall of the upper housing 310 of the regeneration module. The side wall is arranged along the radial direction of the fan. The regeneration airflow flows in the direction opposite to or in the same direction as the rotation direction of the turntable. The regeneration airflow enters the third airflow passage from the heater air inlet 311, passes through the air holes on the air equalizing plate 330, and enters the heater accommodating area to exchange heat with the heating tube 340. The heated high-temperature regeneration airflow passes through the turntable 200 from top to bottom, dehydrating and drying part of the turntable 200 in the regeneration area. The heating tubes 340 are arranged in an S-shape, with their lengths parallel to the side wall facing the heater air inlet 311. The heating tubes 340 are spaced apart along the radial direction of the fan shape. The air holes on the air equalizing plate 330 are provided corresponding to the heating tubes 340. Therefore, the air holes on the air equalizing plate 330 farther from the heater air inlet 311 are arranged closer together and have larger diameters. The placement of the air holes controls the flow rate of the heated, high-temperature regeneration airflow. The turntable 200 adsorbs moisture from the humid circulating airflow through the dehumidifying region. As the turntable 200 rotates into the regeneration region, a large flow rate of the high-temperature regeneration airflow first dehydrates and dries a portion of the turntable 200. As the turntable 200 rotates through the regeneration region, the flow rate of the high-temperature regeneration airflow gradually decreases, thereby more uniformly heating and drying the turntable 200.
