[0006] The present application relates to the technical field of home appliance manufacturing, in particular to heating devices, drying modules and clothing treatment equipment. [Background technology]

[0007] As people's living standards improve and science and technology and product performance continue to improve, people are placing increasing demands on the functionality of home appliances, thereby meeting the increasing demands of household use and reducing the amount of labor required. Laundry, one of the most time-consuming physical tasks in the home, involves the entire laundry process, including washing, hanging to dry, storing, and organizing. Traditional washing machines can only perform the washing function; drying in the sun, storing, and organizing still require manual labor. The newly released washer-dryers combine washing and drying functions, can be started with the push of a button, and can dry clothes after washing, significantly reducing the labor required for hanging to dry and storing.

[0008] The inventors discovered that the rotating wheel of current washing and drying machines adsorbs moisture from the humid airflow discharged from the drum, and a heating module is used to desorb moisture from the rotating wheel, but the temperature of the heating module cannot usually be adjusted, and if the temperature of the heating module is too high, power consumption is high and energy consumption is likely to increase, and if the temperature of the heating module is too low, the moisture absorption efficiency of the rotating wheel decreases and drying time is prolonged. Summary of the Invention

[0009] (1) Purpose of the application The present application aims to provide a heating device, a drying module and a clothes treatment facility.

[0010] (2) Technical proposal A first aspect of the present application is a heating device,

[0011] A heating device is provided, which includes a heater housing having an accommodation space therein, a heater provided within the accommodation space, and a temperature regulator provided outside the heater housing, wherein an end of the heater extends outside the heater housing, and the temperature regulator is connected to the heater to adjust the operating temperature of the heater.

[0012] A second aspect of the present application provides a drying module including the heating device according to any one of the above technical solutions.

[0013] A third aspect of the present application provides a laundry treatment facility, including a drying module according to any one of the above technical solutions or a heating device according to any one of the above technical solutions.

[0014] (3) Beneficial Effects The above technical solution of the present application has the following beneficial technical effects:

[0015] In the technical solution of the present application, the heater power can be adjusted by a temperature regulator to increase or decrease the heater operating temperature. The heater is used to heat the regenerated airflow that flows into the heater housing's storage space, and the heated regenerated airflow passes through the turntable to dehydrate and dry the turntable portion in the regenerative area. By installing the temperature regulator outside the heater housing, damage to the temperature regulator caused by long-term exposure to a hot and humid environment can be avoided. Furthermore, a temperature detector can be installed in the storage space to detect the temperature of the regenerated airflow within the storage space. When the laundry processing device performs a dehydration or drying process, if the detected regenerated airflow temperature is too low, the temperature regulator can increase the heater power, thereby increasing the heater operating temperature, and thereby increasing the heating temperature of the regenerated airflow. If the detected regenerated airflow temperature is too high, the temperature regulator can decrease the heater power, thereby decreasing the heater operating temperature, and thereby decreasing the heating temperature of the regenerated airflow. This not only improves the moisture absorption efficiency of the turntable and shortens the drying time, but also saves energy. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] In order to better understand the above technical solution, the technical solution of the embodiments of the present application will be described in detail below through drawings and specific examples. It should be understood that the embodiments of the present application and the specific features in the embodiments are intended to explain the technical solution of the embodiments of the present application in detail, and do not limit the technical solution of the present application. It should be understood that the embodiments of the present application and the technical features in the embodiments can be combined with each other as long as there is no contradiction.

[0019] To further clarify the objectives, technical solutions, and advantages of the present application, the present application will be described in more detail below with reference to the drawings based on specific embodiments. It should be understood that these descriptions are merely illustrative and do not limit the scope of the present application. In the following description, descriptions of known structures and technologies will be omitted to avoid unnecessary confusion of the concepts of the present application. A first aspect of the present application provides a heating device, as shown in FIGS. 1 to 4, including a heater housing 11, a heater, and a temperature regulator 12. An accommodation space is provided inside the heater housing 11, a heater is provided within the accommodation space, and the temperature regulator 12 is provided outside the heater housing 11, with an end of the heater extending outside the heater housing 11. The temperature regulator 12 is connected to the heater to adjust its operating temperature. The temperature regulator 12 can adjust the power of the heater to increase or decrease the operating temperature of the heater. A dry, low-temperature airflow is passed through the heater housing 11, where it exchanges heat with the heater, heating the dry, low-temperature airflow and becoming a dry, high-temperature airflow. The moisture absorption / desorption member includes a rotatable turntable, at least a portion of which can absorb moisture from the humid circulating airflow within the drum during use. The heater is installed adjacent to another portion of the turntable, and the dry, high-temperature airflow desorbs moisture from that portion, resulting in a humid, hot airflow. The airflow within the storage space desorbs moisture from the other portion of the turntable after heating, further restoring the turntable's moisture absorption capacity and allowing the turntable to be reused. Therefore, the airflow within the storage space can be defined as a regenerative airflow. By installing the temperature controller 12 outside the heater housing 11, damage to the temperature controller 12 due to long-term exposure to a high-temperature, high-humidity environment can be avoided. Furthermore, a temperature detector can be installed within the storage space to detect the temperature of the regenerative airflow within the storage space.When the laundry treatment equipment is performing the dehydration or drying process, if the detected temperature of the regenerated airflow is too low, the temperature controller 12 can adjust the heater power to a larger value, thereby increasing the heater's operating temperature and thereby improving the heating temperature of the regenerated airflow; if the detected temperature of the regenerated airflow is too high, the temperature controller 12 can adjust the heater power to a smaller value, thereby decreasing the heater's operating temperature and thereby lowering the heating temperature of the regenerated airflow. In this way, the moisture absorption efficiency of the turntable can be improved, and the drying time can be shortened, as well as energy can be saved.

[0020] In some embodiments, the temperature regulator is configured as a thermostat to control the on / off of the heater, and / or as a silicon-controlled rectifier to adjust the heater's power. When the temperature regulator is configured as a silicon-controlled rectifier, the heater's power / temperature can be adjusted. By controlling the signal input, a silicon-controlled rectifier (thyristor) module connected in series to the main circuit is controlled to turn on and off the voltage in the main circuit, thereby controlling the heater. By applying a pulse with the same period as the current to the trigger pole of the silicon-controlled rectifier, the silicon-controlled rectifier can control the average voltage in the rectifier circuit according to changes in the phase difference between the pulse and the current, thereby adjusting the heater temperature. When the temperature regulator is configured as a thermostat, the heater is turned off if the heater's operating temperature becomes abnormal (e.g., if the temperature is too high). After the temperature returns to normal, the heater can be turned on manually or automatically.

[0021] If the heater housing 11 is made of stainless steel, its complex structure requires punching and deep drawing to form a recessed space in the heater housing 11 to accommodate the heater. However, stainless steel is not easily deep-drawn, and cracks and wrinkles may occur during the deep-drawing process. Wrinkles and cracks in the heater housing 11 can lead to poor sealing, increase the heater device reject rate, and increase overall costs. In light of these issues, in some embodiments, the heater housing 11 has an integrated structure formed from cast aluminum. The heater housing 11 is die-cast from an aluminum alloy, allowing for the manufacture of heater housings 11 with complex structures while simplifying the manufacturing process and reducing processing costs. The recessed space is less likely to crack during deep-drawing, and the end surfaces of the heater housing 11 are flat and less likely to wrinkle, thereby improving the yield of heater manufacturing, reducing manufacturing costs, and improving the end-face sealing performance. In some embodiments, the heater housing 11 includes a base 111, a top wall 112, and a sidewall 113 that protrudes from the top wall 112. The top wall 112 and the sidewall 113 are arranged around the heater housing 111 to form a storage space. The base 111 is installed along the periphery of the sidewall and extends outward away from the storage space. The top wall 112 and the sidewall 113 are arranged around the heater housing 111 to form a recessed storage space. The heater is mounted within the storage space. The bottom of the heater housing 11 is open, allowing communication with another part of the rotating disk when the heater housing 11 is installed adjacent to the heater housing. The base 111 can be connected to and fixed to the rotating disk heater housing. The bottom of the base can have a flat edge. A sealing pad can be used to improve sealing performance when sealing with the rotating disk heater housing. A cross-shaped rib can be provided on the outside of the top wall 112 to reduce weight, and a ribbed plate can be provided between the sidewall 113 and the base 111 to improve the overall strength of the heater housing 11.

[0022] In some embodiments, the heater housing 11 has a fan-shaped structure, and the sidewalls 113 include two second sidewalls, a first sidewall, and a third sidewall arranged along the radial direction of the fan. Both ends of the first sidewall and the third sidewall are connected to the two second sidewalls. The length of the first sidewall is longer than the third sidewall. The first sidewall is arranged along the outer arc of the fan, and the air inlet 16 is provided in the first sidewall. In this embodiment, the heater housing 11 has a fan-shaped structure in a preferred form. However, the heater housing 11 may have an irregular structure, and this is not intended to be excessively limiting. The heater housing 11 is connected to the turntable upper housing 210 to separate the moisture absorption region and the regeneration region, i.e., the moist circulating airflow in the moisture absorption region and the regeneration airflow in the regeneration region can be largely isolated.

[0023] In some embodiments, the heating device further includes an air conditioning plate 13 having spaced-apart air vents 14. The air conditioning plate 13 is fan-shaped and installed within the accommodation space. The air conditioning plate 13 is spaced apart from and substantially parallel to the top wall 112, and the air conditioning plate 13 and the top wall 112 are connected and fixed by a connecting member. A gap is defined between the air conditioning plate 13 and the top wall of the heater housing 11 to form an airflow passage, which communicates with the air inlet 16. The air conditioning plate 13 and the top wall can be detachably connected by a screw fastener. A gasket can be installed between the air conditioning plate 13 and the top wall to maintain a constant gap between them. The installation of the air vents 14 can adjust the intake volume of the regenerative airflow and further allow the regenerative airflow to be uniformly introduced into the heater for heat exchange.

[0024] In some embodiments, the heater includes at least one heating tube or a plurality of end-to-end connected heating tubes 15, the heating tubes 15 spaced apart along the radial direction of the fan, the length of the heating tubes 15 extending perpendicular to the radius of the fan, the ends of the heating tubes 15 extending outward from the second sidewall, the temperature regulator 12 mounted on the second sidewall, and the ends of the temperature regulator 12 and the heating tube 15 mounted on the same second sidewall, where the temperature regulator 12 is connected to the heating tube 15 to adjust the operating temperature of the heating tube 15. The temperature regulator 12 is mounted outside the heater housing 11 to prevent damage to the temperature regulator 12 from long-term exposure to a high temperature and humidity environment. The heating tubes 15 are distributed in an S-shape, and the length distribution of the heating tubes 15 in the housing space is longer, which increases the contact area with the regenerative airflow and thereby improves the heat exchange efficiency with the regenerative airflow. In some embodiments, the heater tube 15 is located between the air regulating plate 13 and the top wall of the heater housing 11, or the air regulating plate 13 is located between the heater tube 15 and the top wall of the heater housing 11. The air regulating plate 13 can be installed upstream or downstream of the heater, but naturally, being located upstream is preferable. The air regulating plate 13 guides the airflow that flows into the heater accommodating space, allowing the regenerative airflow to sufficiently transfer heat from the heater to the rotating disk. In this case, the heater is located closer to the rotating disk, while the air regulating plate 13 is installed at a distance from the rotating disk. The air regulating plate 13 can also be installed downstream of the heater. The advantage of this arrangement is that the regenerative airflow first comes into sufficient contact with the heater, uniformly heating the regenerative airflow, and then the hot airflow is guided to the turntable by the air adjusting plate 13. In this case, the air adjusting plate 13 is installed adjacent to the turntable, while the heater is installed at a distance from the turntable, and the air adjusting plate 13 not only makes the airflow and guides it uniform, but also protects the heating tube 15 to some extent. The air adjusting plate 13 can also be omitted, and the regenerative airflow can flow directly to the turntable after passing through the heater, which can reduce costs and the complexity of the mechanism.

[0025] In some embodiments, the air holes 14 are arranged in rows, the positions of the air holes 14 in each row corresponding to the positions of the heater tubes 15, the heater tubes 15 being located below the air holes 14, and the axes of the heater tubes 15 being offset from the center lines of the air holes 14 in each row, so that the center lines of the air holes 14 in each row are closer to the air inlet 16 than the axes of the heater tubes 15. When the regeneration airflow is blown in from the heater air inlet 16 and blows inward along the radial direction of the fan, there is a velocity along the flow direction of the regeneration airflow. Therefore, by setting a slight offset to the center lines of the air holes 14 in each row, the regeneration airflow passing through the air holes 14 can face the heater tubes 15, thereby achieving higher heat exchange efficiency between the regeneration airflow and the heater tubes 15.

[0026] In some embodiments, the heating device further includes a fixing member 17 attached to the air adjusting plate 13 to fix the position of the heating tube 15 relative to the air adjusting plate 13. The fixing member 17 includes a first body and a second body. One side of the first body is connected to and fixed to the air adjusting plate 13, and the opposite side of the first body is provided with at least one first semicircular hole that fits the heating tube 15. The second body is provided with at least one second semicircular hole that fits the heating tube 15, and the first and second semicircular holes are arranged in pairs. By fixing the heating tube 15 to the air adjusting plate 13 with the fixing member 17 and increasing the thickness of the first body, a certain gap can be maintained between the heating tube 15 and the air adjusting plate 13, allowing the regeneration airflow to pass through, thereby achieving higher heat exchange efficiency between the regeneration airflow and the heating tube 15. The first body and the second body can be provided with two pairs of first and second semicircular holes arranged side by side, and a screw fastener can be installed between the two pairs of first and second semicircular holes, thereby allowing the two parallel-arranged heating tubes 15 to be fastened to the fixing member 17 simultaneously, thereby making the structure compact.

[0027] A second aspect of the present application provides a drying module including a moisture absorption and desorption member, at least a portion of which adsorbs moisture from a wet circulating airflow within a drum, and a heating device disposed adjacent to at least another portion of the moisture absorption and desorption member and for discharging at least a portion of the moisture adsorbed by at least another portion of the moisture absorption and desorption member. The moisture absorption and desorption member includes a rotatable turntable and a drive assembly, and the drive assembly may include a motor capable of driving the rotation of the turntable. The turntable may be made of a highly hygroscopic material, 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 housing, and the wet circulating airflow in the moisture absorption region passes through the turntable from bottom to top. The turntable adsorbs moisture in the wet circulating airflow, converting it into a dry circulating airflow. The dry circulating airflow then passes through the drum air intake and enters the drum, where it comes into sufficient contact with the clothes, improving drying efficiency and reducing energy consumption. In an embodiment of the present application, the heating device may include a heater housing 11, a heater, and a temperature regulator 12. The heater housing 11 has a recessed storage space, the heater is disposed within the storage space, and the temperature regulator 12 is disposed outside the heater housing 11, with an end of the heater extending outside the heater housing 11. The temperature regulator 12 is connected to the heater to adjust its operating temperature. The temperature regulator 12 adjusts the heater's power to increase or decrease its operating temperature. A dry, low-temperature regeneration airflow is passed through the storage space of the heater housing 11, where it exchanges heat with the heater. The heater is used to heat the regeneration airflow. The heated regeneration airflow passes through a turntable in the regeneration zone for dehydration drying. During the rotation process, the turntable cyclically passes through a moisture absorption zone and a regeneration zone, continuously adsorbing and desorbing moisture. In this way, the dry circulating airflow continuously enters the drum and comes into sufficient contact with the clothes, improving drying efficiency and reducing energy consumption. By locating the temperature regulator 12 outside the heater housing 11, damage to the temperature regulator 12 due to long-term exposure to a high temperature and humidity environment can be prevented.In addition, a temperature detector is installed in the storage space to detect the temperature of the recycled airflow in the storage space, and when the laundry processing equipment is performing the dehydration or drying process, if the detected recycled airflow temperature is too low, the temperature controller 12 can increase the heater power to raise the heater's operating temperature and thereby improve the heating temperature of the recycled airflow, and if the detected recycled airflow temperature is too high, the temperature controller 12 can decrease the heater power to lower the heater's operating temperature and thereby lower the heating temperature of the recycled airflow. In this way, the moisture absorption efficiency of the turntable can be improved, and the drying time can be shortened, as well as energy can be saved.

[0028] The turntable 200 can be made of a highly hygroscopic material, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The turntable components may include the turntable 200 and a drive assembly, which may include a motor for driving the rotation of the turntable 200. The wet circulating airflow discharged from the drum enters the bottom of the turntable chamber. The wet circulating airflow in the moisture absorption region 1-1 passes through the turntable 200 from bottom to top. The turntable 200 absorbs moisture and converts it into a dry circulating airflow. The dry circulating airflow passes through the drum air inlet and enters the drum, where it fully contacts the clothes, improving drying efficiency and reducing energy consumption. During this process, the wet circulating airflow may carry some fine lint with it and enter the turntable 200, where it may adhere to the clothes as it passes through the turntable 200. The regeneration component may include a heater for heating the regenerated airflow, and the temperature of the regenerated airflow after heating can reach 140 to 200°C. In this way, during the regeneration process of the turntable 200, fine lint is easily combusted by the high temperature, and if it is exposed to such a high-temperature and humid environment for a long period of time, bacteria and viruses are likely to grow in the combusted material, and the bacteria and viruses may enter the drum with the circulating airflow and contaminate clothes.

[0029] To address this problem, an embodiment of the present application provides a drying module including a turntable, a turntable housing, and a heating device including a first heater 320 and a second heater 330, as shown in FIGS. 3 to 7. The turntable housing is used to house the turntable, and is divided into at least a moisture absorption zone 1-1, a regeneration zone 1-2, and a deodorization zone 1-3 in the rotation direction of the turntable. The deodorization zone 1-3 is located downstream of the regeneration zone 1-2. The first heater 320 is installed corresponding to the regeneration zone 1-2 and is used to desorb moisture adsorbed on at least a portion of the turntable that has rotated through the regeneration zone. The second heater 330 is installed corresponding to the deodorization zone 1-3. The first heater 320 can be used to heat the regeneration airflow to desorb a portion of the moisture adsorbed on the turntable. The second heater 330 can be used to heat the deodorization airflow to partially remove combustion products generated on the turntable during the regeneration process. Here, the first heater 320 and the second heater 330 are installed adjacent to the turntable 200, and the second heater 330 is installed downstream of the first heater 320 in the direction of rotation of the turntable 200. The first heater 320 and the second heater 330 may be, for example, independent modules, each including an independent heating tube, and the heating temperature change can be controlled by controlling the power of the heating tube. The first heater 320 and the second heater 330 may be installed above the turntable 200, preferably at a height that does not contact the turntable 200. During the rotation process, the turntable 200 may first pass through a regeneration zone 1-2 corresponding to the first heater 320, and then through a deodorization zone 1-3 corresponding to the second heater 330. The regenerated airflow passes through the first heater 320, and the temperature of the regenerated airflow after heating can reach 140 to 200°C, and the deodorized airflow passes through the second heater 330, and the temperature of the deodorized airflow after heating can reach 250°C or higher.The heated regeneration airflow passes from top to bottom through the turntable 200, dehydrating and drying the portion of the turntable 200 in the regeneration area. The heated deodorization airflow passes from top to bottom through the turntable 200, removing the combustion materials from the portion of the turntable 200 in the deodorization area. The high temperature carbonizes the combustion materials, preventing the generation of bacteria and viruses caused by prolonged exposure to a hot and humid environment, thereby achieving the effects of sterilization and deodorization. As shown in FIG. 9, the turntable housing can be divided into three operating areas: moisture absorption area 1-1, regeneration area 1-2, and deodorization area 1-3. In moisture absorption area 1-1, the wet circulating airflow from inside the drum passes from bottom to top through the turntable 200, which absorbs moisture from the wet circulating airflow and converts it into a dry circulating airflow. 9 indicates the direction of rotation of the turntable 200, which circulates through the moisture absorption zone 1-1, the regeneration zone 1-2, and the deodorization zone 1-3 in order during the rotation process, continuously performing moisture adsorption, moisture desorption, and sterilization and deodorization. In this way, clean, dry circulating air continuously enters the drum and fully contacts the clothes inside, improving drying efficiency and reducing energy consumption.

[0030] In some embodiments, the turntable housing has a heater mounting portion in communication with the turntable, the heater mounting portion including at least a first heater receiving area and a second heater receiving area, the first heater being mounted in the first heater receiving area to form a regeneration area, and the second heater being mounted in the second heater receiving area to form a deodorization area, the first heater 320 being located in the regeneration area, and the second heater 330 being located in the deodorization area, the deodorization area being located downstream of the regeneration area with respect to the direction of rotation of the turntable. In some embodiments, the drying module further includes a heater housing, and both the first heater and the second heater are housed within the heater housing. Specifically, the heater housing may include a top wall 112, a side wall 113 extending from the periphery of the top wall 112 to form a housing chamber, and a base 111 extending outward along the side wall 113. The base 111 may have mounting holes through which the heater housing can be connected and fixed to the turntable upper housing 210. The first heater 320 and the second heater 330 may each include independent heating tubes with an S-shaped distribution. The length distribution of the heating tubes in the regeneration zone and the deodorization zone may be longer, thereby increasing the contact area with the regeneration airflow and the deodorization airflow, thereby achieving more efficient heat exchange with the regeneration airflow and the deodorization airflow. The change in heating temperature can be controlled by controlling the power of the heating tubes. The heating tube heats the surface of the turntable 200, and during the rotation process, the turntable 200 can first pass through the first heater 320 and then the second heater 330. After heating, regeneration airflow and deodorization airflow with different temperatures are set up and pass through the turntable 200 from top to bottom, respectively, to heat the turntable 200 more uniformly, thereby realizing the moisture desorption and sterilization / deodorization process for the turntable 200 portion.

[0031] In some embodiments, the first heater operates at a first temperature, and the second heater operates at a second temperature, the second temperature being higher than the first temperature. The first temperature may be, for example, 140 to 200°C to heat the regeneration airflow, which passes from top to bottom through the turntable 200 to dehydrate and dry the portion of the turntable 200 in the regeneration zone. The second temperature may be, for example, 250°C or higher to heat the deodorization airflow, which passes from top to bottom through the turntable 200 to remove combustible materials from the portion of the turntable 200 in the deodorization zone, which carbonizes the combustible materials. In some embodiments, the temperature of the heated deodorizing airflow is higher than the temperature of the heated regenerating airflow. The regenerating airflow passes through the first heater 320, and the temperature of the heated regenerating airflow can be set to 140-200°C. The deodorizing airflow passes through the second heater 330, and the temperature of the heated deodorizing airflow can be set to 250°C or higher. In tests, contaminated and discolored turntables 200 were sampled to obtain four samples, which were then baked at 150°C, 200°C, 300°C, and 400°C. At 250°C, the carbon deposits on the samples began to thin, and at 400°C, the carbon deposits were completely removed. Therefore, setting the temperature of the heated deodorizing airflow to 250°C or higher can achieve sterilization and deodorization of the turntable 200.

[0032] In some embodiments, a first partition member 340 is installed in the heater housing along a substantially radial direction, and the first heater 320 and the second heater 330 are installed on either side of the first partition member 340 to separate the interior space of the heater housing. The heater housing has a fan-shaped structure, and the first partition member 340 is installed in the storage chamber and extends along the radial direction of the fan-shaped structure to divide the storage chamber into a regeneration zone and a deodorization zone. The first partition member 340 can be made of a thermal insulating material, thereby allowing for relatively accurate control of the heating temperatures of the regeneration zone and the deodorization zone. One end of the first partition member 340 is connected to the outer arc-shaped sidewall of the heater housing, and the other end extends in the centrifugal direction of the fan-shaped structure and is connected to the sidewall of the heater housing, thereby dividing the storage chamber into a regeneration zone and a deodorization zone. In other embodiments, the first partition member 340 may not be installed in the storage chamber. The heating tubes heat the surface of the turntable 200, so by actively controlling the power of the two heating tubes, the heating temperature can be roughly controlled, and heat can be freely transferred between the two areas, which can also achieve a certain degree of energy saving.

[0033] In some embodiments, the area of ​​the first heater housing area is equal to or larger than the area of ​​the second heater housing area. That is, the area of ​​the regeneration area can be set to be equal to or larger than the area of ​​the deodorization area. In order to recover the moisture absorption capacity after desorbing moisture from the turntable 200, the area of ​​the regeneration area can be set to be larger than the area of ​​the deodorization area, thereby further improving the drying efficiency and drying effect of desorbing moisture from the turntable 200.

[0034] In some embodiments, the heater housing has an outer arc-shaped sidewall or a generally radial sidewall provided with air inlets, including a first air inlet and a second air inlet. The first air inlet is used to draw air into the first heater space, and the second air inlet is used to draw air into the second heater space. In an exemplary embodiment, the heater housing has an outer arc-shaped sidewall provided with an air inlet 16 communicating with the storage chamber. In the preferred embodiment of the present application, the heater housing has a fan-shaped structure, but the heater housing may have an irregular structure, and this is not intended to be excessively limiting. The heater housing is connected to the turntable upper housing 210 to separate the moisture absorption area from the regeneration area and the deodorization area, i.e., the moisture circulation airflow in the moisture absorption area can be largely isolated from the regeneration airflow and the deodorization airflow. Specifically, the same airflow having the same flow velocity and direction enters the storage chamber through the air inlet, and after being heated by the first heater 320, a regenerating airflow can be obtained, and after being heated by the second heater 330, a deodorizing airflow can be obtained.

[0035] In an exemplary embodiment, the air inlet 16 includes a first air inlet and a second air inlet, which may be provided at both ends adjacent to the outer arc-shaped sidewall of the housing. The first air inlet is connected to the regeneration zone to desorb moisture adsorbed on the turntable after the regeneration airflow is heated. The second air inlet is connected to the deodorization zone to remove combustion products generated by the turntable during the regeneration process after the deodorization airflow is heated. Specifically, the first air inlet and the second air inlet are provided on the outer arc-shaped sidewall of the heater housing, and the top end of the first partition member 340 is connected to the top wall 112 of the heater housing to divide the chamber into the regeneration zone and the deodorization zone. Two separate airflows are passed through the first air inlet and the second air inlet, respectively, and the flow rates of the two airflows can be controlled. For example, the flow rate of the airflow leading to the regeneration area may be relatively large, and the flow rate of the airflow leading to the deodorization area may be relatively small. In order to easily adjust and control the flow rates of the two airflows, the two airflows may be two separate airflows from the outlet of the same fan, or may be airflows provided by two independent fans. The embodiments of the present application are not excessively limited.

[0036] In some embodiments, the heater housing includes a first heater housing and a second heater housing, where the first heater 320 is housed in the first heater housing and the second heater 330 is housed in the second heater housing. In this manner, the first heater 320 and the second heater 330 are provided in two independent modules, enabling precise control of the heating temperatures for the first heater 320 and the second heater 330.

[0037] In some embodiments, the first heater housing and the second heater housing are provided on their outer arcuate or generally radial side walls with a first air inlet and a second air inlet for drawing air into the first heater space and the second heater space, respectively. The first air inlet is provided on the outer arcuate or generally radial side wall of the first heater housing, and the second air inlet is provided on the outer arcuate or generally radial side wall of the second heater housing, thereby achieving precise control over the two air flows, the regeneration air flow and the deodorization air flow.

[0038] In an exemplary embodiment, the intake air volume of the first air inlet is equal to or greater than the intake air volume of the second air inlet. In this way, the flow rate of the regeneration airflow can be controlled to be greater than the flow rate of the deodorization airflow. In order to restore the moisture absorption capacity after desorbing moisture from the turntable 200, the flow rate of the regeneration airflow can be set to be greater than the flow rate of the deodorization airflow, thereby further improving the drying efficiency and drying effect of desorbing moisture from the turntable 200 and preventing the temperature of the discharge airflow from becoming too high due to an excessive flow rate of the deodorization airflow.

[0039] In some embodiments, the drying module further includes an air balance member that can be located above or below the first heater 320 and the second heater 330; i.e., the air balance member is located adjacent to or spaced apart from the rotating disk. The regeneration airflow enters the regeneration area and passes through the air balance member / first heater 320, the first heater 320 / air balance member, and the rotating disk, in that order. The deodorization airflow enters the deodorization area and passes through the air balance member / second heater 330, the second heater 330 / air balance member, and the rotating disk, in that order. Here, the balance partition member may be an air adjustment plate, and the air balance member is fan-shaped and has spaced-apart air vents 14. The air balance member can be located upstream or downstream of the first heater 320 and the second heater 330, although an upstream location is naturally preferred. The air balance member guides the airflow flowing into the heater accommodating space through the air vents 14, allowing the regeneration airflow and deodorization airflow to fully transfer heat from the heater to the turntable 200. In this case, the heaters are located closer to the turntable, while the air balance member is installed at a distance from the turntable. The air balance member can also be installed downstream of the first heater 320 and the second heater 330. The advantage of this arrangement is that the regeneration airflow first comes into sufficient contact with the heater, uniformly heating the regeneration airflow and deodorization airflow, and then the guide of the air balance member allows the heated airflow to flow to the turntable 200. In this case, the air balance member is installed adjacent to the turntable, while the heater is installed at a distance from the turntable. The air balance member not only uniforms the airflow and guides it, but also protects the heater's heating tube to some extent. The air balance member can be omitted and the regenerating airflow and the deodorizing airflow can flow directly to the rotating disk after passing through the heater, which can reduce the cost and complexity of the mechanism.

[0040] In some embodiments, the drying module may specifically include a circulation module 10, a dehumidifying module 20, and a heating device 30, as shown in FIG. 8. The circulation module 10 has a first circulation path connected to the drum exhaust port so that the moist circulating airflow in the drum enters the first circulation path. The dehumidifying module has a second circulation path, and the dehumidifying module 20 is located downstream or upstream of the circulation module 10. The drum exhaust port, the first circulation path, the second circulation path, and the drum intake port are sequentially connected to form the circulation path. The dehumidifying module 20 includes a moisture absorption / desorption member, at least a portion of which is installed in the second circulation path and is used to adsorb moisture in the moist circulating airflow from inside the drum. The heating device 30 includes a first heater 320 and is used to heat the regeneration airflow to desorb a portion of the moisture adsorbed on the rotating disk. The second heater 330 is used to heat the deodorized airflow to remove some of the combustion products generated by the turntable during the regeneration process. The circulation module 10 may include a circulation fan, which can provide power to the wet circulating airflow and help circulate the airflow. The circulation fan's air inlet is connected to the drum exhaust port, and its air outlet is connected to the second circulation path. A moisture absorption and desorption member is installed in the second circulation path. The moisture absorption and desorption member can first adsorb moisture in the wet circulating airflow from inside the drum and convert it into a relatively dry circulating airflow. The dry circulating airflow passes through the drum air inlet and enters the drum, where it fully contacts the clothes, improving drying efficiency and reducing energy consumption. To allow the moisture absorption and desorption members to be used continuously and repeatedly, the regeneration airflow passes through the first heater 320, and the temperature of the regeneration airflow after heating can reach 140 to 200°C, and the deodorization airflow passes through the second heater 330, and the temperature of the deodorization airflow after heating can reach 250°C or higher. The heated regeneration airflow passes through the turntable 200 from top to bottom to dehydrate and dry the portion of the turntable 200 in the regeneration area, and the heated deodorization airflow passes through the turntable 200 from top to bottom to remove combustible materials from the portion of the turntable 200 in the deodorization area.Therefore, the turntable 200 circulates through the moisture absorption zone, regeneration zone, and deodorization zone in sequence during the rotation process, continuously performing moisture absorption, moisture desorption, and sterilization / deodorization. In this way, clean, dry circulating airflow continuously enters the drum and fully contacts the clothes, improving drying efficiency and reducing energy consumption. Here, the moisture absorption / desorption member may be, for example, the turntable 200.

[0041] In some embodiments, the turntable housing may include a turntable upper housing 210 and a turntable lower housing 220. A generally fan-shaped heater mounting portion is formed in the turntable upper housing 210, and a heating device is mounted on the heater mounting portion, thereby allowing the turntable 200 to be located above the heater mounting portion. In an exemplary embodiment, a first turntable accommodating area may be formed in the turntable lower housing 220. The turntable lower housing 220 may include a bottom plate and a peripheral side wall protruding from the bottom plate, and the formed recess is the first turntable accommodating area. Similarly, a second turntable accommodating area may be formed in the turntable upper housing 210. The second turntable accommodating area includes at least a moisture absorption area but does not include a regeneration area or a deodorization area, and a heater mounting portion is installed on a radial edge of the second turntable accommodating area. The second turntable accommodating area and a portion of the first turntable accommodating area jointly form at least the moisture absorption area, and the heater mounting portion and another portion of the first turntable accommodating area jointly form the regeneration area and the deodorization area. To allow airflow within the turntable receiving chamber, a sealing connection can be provided between the turntable upper housing 210 and the turntable lower housing 220. For example, a groove or flange can be provided on the turntable upper housing 210 or the turntable lower housing 220, respectively, with a sealing strip installed in the groove, and when the turntable upper housing 210 and the turntable lower housing 220 are snap-connected, the flange presses against the sealing strip in the groove to achieve a seal.

[0042] 5, in some embodiments, the heating device 30 has a first airflow path, and the drying module is installed in the first airflow path and further includes a fan 301 located upstream of the heating device 30. The first airflow passes through a first air inlet and a second air inlet and is separated into two airflows to enter the regeneration area and the deodorization area, respectively, to form a regeneration airflow and a deodorization airflow. The installation of the fan 301 can provide power to the first airflow, which helps to circulate the first airflow and improve its efficiency.

[0043] In some embodiments, the drying module further includes a condensing module 40, which may specifically include a first condenser 7 installed in the first airflow path. The first condenser 7 is located downstream of the turntable 200 and upstream of the fan 301, so that the humid and high-temperature recycled airflow and deodorized airflow in the first airflow path enter the first condenser 7 and are transformed into a dry and low-temperature first airflow to enter the fan 301, and the first airflow forms a closed-circuit circulation. When the turntable 200 rotates in the first airflow path, the first airflow can be transformed into two airflows, i.e., a recycled airflow and a deodorized airflow. As shown in Figure 7, the regeneration airflow passes through the turntable 200 from top to bottom, heating that portion of the turntable 200 and rapidly evaporating and desorbing moisture from that portion, which is then carried away by the regeneration airflow. Meanwhile, the deodorization airflow passes through the turntable 200 from top to bottom, heating that portion of the turntable 200 and removing carbon deposits from that portion of the turntable 200, achieving sterilization and deodorization. At this time, the regeneration airflow and the deodorization airflow merge with the humid, high-temperature first airflow and enter the first condenser 7, allowing the turntable 200 to maintain good moisture absorption capacity and further improving the efficiency and effectiveness of moisture absorption by the turntable 200. The arrows in Figure 7 indicate the flow direction of the first airflow. In an exemplary embodiment, the humid and hot first airflow enters the first condenser 7, where it undergoes heat exchange and its temperature drops, the water vapor in the first airflow is cooled to form condensed water, and is discharged from the first condenser 7; the dry and cold first airflow enters the fan 301 to begin the next cycle. In an alternative embodiment, the humid and hot first airflow enters the first condenser 7, where it undergoes heat exchange and its temperature drops, the water vapor in the first airflow is cooled to form condensed water, and is discharged from the first condenser 7; the dry and cold first airflow can be discharged into the atmosphere through the air outlet of the first condenser 7, thereby avoiding adverse effects on the atmospheric temperature and humidity in the space where the laundry treatment equipment is located. Therefore, the first airflow can form an open circulation.

[0044] 10 to 13, the drying module includes a turntable housing 411, a turntable 200, and a sealing structure. The turntable housing 411 is provided with a recessed storage space, a second partition member 412 is provided within the turntable housing 411 to separate the storage space into a first circulating air duct and a second circulating air duct, the turntable 200 is attached to the turntable housing 411 to cover the first circulating air duct and the second circulating air duct, and the turntable 200 is rotatably connected to the turntable housing 411. A sealing structure is located between the turntable 200 and the turntable housing 411, and the sealing structure is attached to the second partition member 412. The sealing structure is adjacent to or in contact with the turntable 200 to prevent airflow communication between the first circulating air duct and the second circulating air duct. To enclose the recessed storage space, the turntable housing 411 may be provided with a bottom wall and a peripheral side wall that protrudes from the bottom wall. A gap is formed between one side of the turntable 200 and the bottom wall, and a protruding second partition member 412 is installed on the bottom wall to separate the storage space into a first circulating air duct and a second circulating air duct. The first circulating air duct may be connected to, for example, the drum exhaust port so that the wet circulating airflow discharged from the drum enters the first circulating air duct. The second circulating air duct may be connected to, for example, the dry regenerating airflow. Therefore, the wet circulating airflow discharged from the drum enters the first circulating air duct and diffuses therein, and the wet circulating airflow can pass through the turntable 200, which adsorbs the moisture in the wet circulating airflow and converts it into a dry circulating airflow. The dry circulating airflow enters the drum through the drum air inlet and comes into sufficient contact with the clothes, improving drying efficiency and reducing energy consumption.At the same time, the dry regenerated airflow enters the second circulating air duct and diffuses therein. The dry regenerated airflow can pass through the turntable 200, desorbing moisture from that portion of the turntable. As the turntable 200 rotates relative to the turntable housing 411, it passes through the first and second circulating air ducts cyclically during its circumferential rotation, continuously adsorbing and desorbing moisture. This ensures that the turntable 200 always has good moisture absorption capacity, thereby improving the efficiency and effectiveness of moisture absorption. By attaching a sealing structure to the second partition member 412 and positioning the turntable 200 and the sealing structure facing its side close to each other without interfering with each other during the rotation process, the two airflows in the first and second circulating air ducts are relatively isolated, achieving a dynamic sealing effect, thereby improving the drying efficiency and reducing energy consumption of the drying module.

[0045] In some embodiments, the turntable housing 411 may include a first housing (also referred to as the turntable upper housing) and a second housing (also referred to as the turntable lower housing). The turntable 200 is located between the first and second housings. For example, a second partition member 412 may be installed on the first housing to form a first circulating air duct and a second circulating air duct. Similarly, a second partition member 412 may be installed on the second housing to form a first circulating air duct and a second circulating air duct. To prevent communication between the humid circulating airflow discharged from the drum and the regenerating airflow, a sealing structure may be installed across the second partition member 412, forming a dynamic sealing effect between the turntable 200 and the second partition member 412. Therefore, during the rotation process, the turntable 200 continuously absorbs moisture and dehydrates through the first and second circulating air ducts, thereby ensuring that the turntable 200 always has good moisture absorption capacity, thereby improving the efficiency and effectiveness of moisture absorption. To balance the turntable 200, the flow directions of the humid circulating airflow and the regenerating airflow can be set to face each other or opposite each other. For example, in the first circulating air duct, the humid circulating airflow can pass through the turntable 200 from bottom to top, and in the second circulating air duct, the regenerating airflow can pass through the turntable 200 from top to bottom.

[0046] In some embodiments, the sealing structure includes a flexible member adjacent to or in contact with the turntable 200. The flexible member may be a soft rubber or bristle strip with a certain amount of elastic deformation, and is adjacent to or in contact with the surface of the turntable 200 without interfering with the rotation of the turntable 200, relatively isolating the two air flows in the first and second circulating air ducts, thereby achieving a dynamic sealing effect. While foamed EPDM is commonly used as a sealing strip in the drying module inside a conventional condenser-type washer-dryer, foamed EPDM is only suitable for sealing between two relatively static parts. If foamed EPDM is used between two relatively dynamic parts, it will quickly wear out and become useless for sealing.

[0047] In view of this, in some embodiments, the flexible member is provided on the brush 414, where the brush 414 includes a brush base and a plurality of closely spaced soft bristles mounted on the brush base. The soft bristles are closely spaced on the brush 414 and can come into contact with the surface of the turntable 200, thereby realizing a seal with the turntable 200 and providing the brush 414 with wear resistance. In this way, the brush 414 will not wear even if the turntable 200 rotates for a long time, which helps to isolate the two air flows in the first and second circulating air ducts from each other and prevent gas leakage, further ensuring the reliability of the equipment over a long period of use.

[0048] In some embodiments, the sealing structure further includes a fixing frame 415, one side of which is snap-connected or screw-connected to the brush base, and the other side of which is connected to and fixed by the second partition member 412. Specifically, bumps can be provided on the brush base, and corresponding grooves can be provided on the fixing frame 415. The bumps can be inserted into the grooves to form an interference fit and fix the relative positions of the brush base and the fixing frame 415, or the brush base and the fixing frame 415 can be screw-connected to achieve relative positional fixation. For example, the brush base can have a screw nut recessed into the brush base to prevent the nut from protruding and interfering with the rotation of the turntable 200. The other side of the fixing frame 415 can have a protruding mounting post, which can be inserted into the second partition member 412 and secured by a screw fastener from the outside of the turntable housing 411, and the screw fastener can be a self-tapping screw. In this way, it is easy to install, the structure is compact, and the sealing structure is not affected by the fast-passing air current and will not be displaced even after long-term use, further ensuring the reliability of use.

[0049] In some embodiments, the second partition member 412 is arranged to be installed along the radial direction of the turntable housing 411 so that the first circulating air duct and the second circulating air duct are both approximately sector-shaped spaces. In this way, the turntable 200 can cyclically pass through the first circulating air duct and the second circulating air duct during the rotation process, so that the moisture adsorption and desorption process is continuously carried out, and the turntable 200 can always maintain good moisture absorption capacity.

[0050] In some embodiments, the second partition member 412 includes at least a first partition body and a second partition body, both of which are arranged along the radial direction of the turntable housing 411, one end of each of the first partition body and the second partition body is connected to the inner wall of the turntable housing 411, and the other ends of the first partition body and the second partition body intersect in the central region of the turntable housing 411 so that the second partition member 412 is approximately V-shaped, and the intersection between the first partition body and the second partition body is an arc transition connection. Both the first partition body and the second partition body can be provided with sealing structures, and both sealing structures are installed along the radial direction of the turntable housing 411. During the rotation process of the turntable 200, the brushes 414 are always in contact with the surface of the turntable 200, thereby isolating the two air flows in the first circulating air duct and the second circulating air duct from each other and preventing gas leakage.

[0051] In some embodiments, the angle between the first and second partitions is set to 60 to 70 degrees. Preferably, the angle between the first and second partitions is set to 65 degrees, with the V-shaped area formed by the angle between the first and second partitions serving as the second circulating air duct, and the remaining area serving as the first circulating air duct. By setting the area of ​​the first circulating air duct larger than that of the second circulating air duct, a larger portion of the turntable 200 is located in the area that adsorbs moisture from the humid circulating airflow, thereby further improving the moisture absorption efficiency and moisture absorption effect of the turntable 200. A certain dynamic sealing effect can be formed between the sealing structure and the turntable 200 to prevent the humid circulating airflow discharged from the drum from communicating with the regenerating airflow. When the turntable 200 rotates in the second circulating air duct, the regenerated airflow heats that part of the turntable 200, and the moisture in that part quickly evaporates and desorbs, and is carried away by the regenerated airflow, so that the turntable 200 always has good water absorption ability, thereby improving the efficiency and effect of moisture absorption.

[0052] In some embodiments, a protruding mounting shaft 416 is provided at the intersection between the first partition and the second partition, and the turntable 200 is rotationally connected to the mounting shaft 416. The mounting shaft 416 can be a fixed shaft or a rotating shaft. When the mounting shaft 416 is a fixed shaft, a drive assembly including a motor that drives the rotation of the turntable 200 can be provided in the circumferential direction of the turntable 200. When the mounting shaft 416 is a rotating shaft, the motor drives the rotation of the rotating shaft to drive the rotation of the turntable 200.

[0053] In some embodiments, the turntable 200 has a porous structure that allows air to pass through it. The turntable 200 can be made of a material that has good moisture absorption and desorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve.

[0054] When clothing treatment equipment such as dryers, washer-dryers, and clothing care appliances dry clothes, the technical solution used may be to dehumidify the air using a drying module. The dehumidification principle of the drying module is that the adsorption medium in the moisture absorption and desorption member mainly adsorbs the moisture in the air, and the adsorption medium adsorbs the moisture in the air by condensation, and the adsorption medium is heated to release the water vapor absorbed by the moisture absorption and desorption member for cyclical use.

[0055] Therefore, the moisture absorption and desorption member usually has an adsorption medium that constitutes a rotating disk, and the dehumidifying rotating wheel is usually divided into two areas, as shown in Figure 14, here including a moisture absorption area 1-1, a regeneration area 1-2 and a mounting shaft 416, and the arrow in the figure is used to indicate the rotation direction of the rotating disk.

[0056] The adsorption medium in the moisture absorption region 1-1 of the turntable adsorbs moisture from the air. At the same time, a driving member such as a drive motor or gear (not shown in FIG. 14 ) drives the rotation of the mounting shaft 416, further rotating the dehumidifying rotating wheel. The adsorption medium in the moisture absorption region 1-1 of the turntable absorbs moisture from the air and dries the air, thereby providing dry air. Driven by the driving member, the turntable rotates the adsorption medium after adsorption, moving it from the moisture absorption region to the regeneration region 1-2. The temperature of the regeneration region 1-2 is higher than that of the moisture absorption region 1-1, and the moisture absorption and desorption member heats up, evaporating and discharging the moisture in the adsorption medium in the regeneration region 1-2. For example, a heater can be used to blow hot air from a fan, or a fan can be heated to evaporate and discharge the moisture absorbed by the adsorption medium in the turntable. The moisture absorption and desorption member then carries away the released moisture from the regeneration region 1-2. The moisture released from the regeneration area 1-2 is removed by various methods, such as using a fan to exhaust the moisture from the air exhaust pipe. The rotating disk continues to rotate as the power member is driven, and the adsorption medium in the regeneration area 1-2 re-enters the moisture absorption area 1-1 to adsorb and dehumidify, realizing the regeneration and reduction of the adsorption medium in the rotating disk.

[0057] The problem with this technical solution is that immediately after the adsorption medium in the regeneration area 1-2 enters the moisture absorption area 1-1, for example, the area from the dotted line in Figure 14 to the edge of the regeneration area 1-2, a certain amount of heat is maintained in the adsorption medium, which affects the dehumidification effect of the moisture absorption area 1-1. Therefore, in the conventional technical solution, the dehumidification efficiency of the drying module is not high, and the dehumidification efficiency of the clothing treatment equipment is low.

[0058] In order to solve the above technical problems, an embodiment of the present application provides a drying module including a clothes treatment container for removing moisture from clothes to form a wet airflow, a moisture absorption and desorption member including, in order, a moisture absorption and desorption region, a regeneration region, and a cooling region, and a first fan for introducing the wet airflow into the moisture absorption and desorption member and introducing a dry airflow dehumidified by the moisture absorption and desorption member into the clothes treatment container, wherein the moisture absorption region is connected to the clothes treatment container and is used to adsorb moisture in the wet airflow, the regeneration region is heated and is used to discharge moisture adsorbed in the moisture absorption and desorption member so as to restore the moisture absorption capacity of the moisture absorption and desorption member, and the cooling region is located upstream of the moisture absorption region and is used to lower the temperature of the moisture absorption and desorption member to improve the dehumidification capacity of the moisture absorption and desorption member, wherein the moisture absorption region, regeneration region, and cooling region are independent of each other. A specific embodiment will now be described.

[0059] FIG. 15 shows a schematic diagram of the external structure of the clothing treatment equipment, FIG. 16 shows a schematic diagram of the lower housing of the drying module of the clothing treatment equipment, and FIG. 17 shows a schematic diagram of the rotating disk area division of the moisture absorbing and releasing member.

[0060] The drying module includes a clothes treatment container 1, a first fan 2, and a moisture absorbing and releasing member 3. As shown in FIG. 15, the clothes treatment container 1 is used to remove moisture from clothes and form a moist airflow. If the clothes treatment equipment is a washer / dryer, the clothes treatment container 1 may be a washing drum, and if the clothes treatment equipment is a dryer, the clothes treatment container 1 may be a drying chamber. Those skilled in the art can determine the specific clothes treatment container 1 according to the different clothes treatment equipment based on the concept of the present application.

[0061] As shown in FIG. 21 , the first fan 2 is used to introduce the wet airflow into the moisture absorption and desorption member 3 and introduce the dry airflow dehumidified by the moisture absorption and desorption member 3 into the clothing treatment container 1. The first fan 2 may be one or more, and is not limited here. It may be installed rationally according to actual needs. If the clothing treatment equipment is a washing / dryer or other equipment, the first fan 2 may have a conventional fan structure. If cost is not a consideration, the first fan may be a refrigeration fan or other fan. The wet airflow removed from the clothing treatment container 1 is introduced into the moisture absorption and desorption member 3, and the dry airflow dehumidified by the moisture absorption and desorption member 3 is introduced into the clothing treatment container 1. The moisture absorption and desorption member 3 may include a moisture absorption region 1-1, a regeneration region 1-2, and a cooling region 33, in that order, along its rotation direction. The moisture absorption region 1-1 is connected to the clothing treatment container 1 and is used to absorb moisture in the wet airflow. The moisture absorption area 1-1 can be connected to the laundry treatment container 1 by installing an air circuit. As will be understood by those skilled in the art, the communication between the moisture absorption area 1-1 and the laundry treatment container 1 means that the air in the moisture absorption area 1-1 and the air in the laundry treatment container 1 can flow and communicate with each other, and the action of the first fan 2 can rapidly circulate the air between the moisture absorption area 1-1 and the laundry treatment container 1.

[0062] In the embodiments of the present application, the communication is a spatial mutual communication. After two spaces are connected, the air in the two spaces can freely alternate, and it may be understood as having a mutually connected air circuit, and the description of this will be omitted below.

[0063] The regeneration zone 1-2 is heated to remove moisture adsorbed by the moisture absorption and desorption member 3, restoring the moisture absorption capacity of the moisture absorption zone 1-1. The cooling zone 33 is installed adjacent to the regeneration zone 1-2 and can be located upstream of the moisture absorption zone 1-1 along the rotation direction of the moisture absorption and desorption member 3. It is used to lower the temperature of the moisture absorption and desorption member 3 and improve the dehumidification capacity of the moisture absorption and desorption member 3. The method for lowering the temperature of the cooling zone 33 is not limited by the technical solution of this embodiment. A fan can be used to generate airflow in the cooling zone 33, which achieves heat exchange through the gas flow and removes heat from the cooling zone 33, thereby achieving the goal of lowering the temperature of the moisture absorption and desorption member 3. A refrigeration unit can also be added, and the low temperature generated by the refrigeration unit can be used to lower the temperature of the turntable. Furthermore, a low-temperature airflow can be transported to the cooling zone 33, thereby achieving the goal of lowering the temperature of the moisture absorption and desorption member 3. Of course, other methods can also be used to lower the temperature of the cooling zone 33. No further enumeration is given here, but those skilled in the art can reasonably design and arrange them based on the actual scene and the concept of the present application.

[0064] In one embodiment of the present application, the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33 are independent of each other. The technical solution for the independence of the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33 is not limited to this embodiment. This independence can be achieved by adding a separator and corresponding sheathing between the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33. This isolation can also be achieved by using a corresponding separator design integrally molded with the moisture absorption / desorption member housing. Furthermore, the independence of each region can be achieved by using other technical solutions proposed by those skilled in the art. As long as the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33 are ensured to be independent of each other, those skilled in the art can reasonably configure them according to the current situation and actual needs. According to the technical solution proposed in this embodiment, a separate cooling region 33 is added to the moisture absorption / desorption member 3, which reduces the temperature of the moisture absorption / desorption member 3 within the cooling region 33, thereby improving the dehumidification ability of the moisture absorption / desorption member 3. By using the mounting shaft 416, the adsorption medium in the cooling region 33 is transferred to the moisture absorption region 1-1, and then the cooling region 33 cools the adsorption medium, so that the cooled adsorption medium enters the moisture absorption region 1-1, thereby ensuring the dehumidifying effect of the adsorption medium in the moisture absorption region 1-1, improving the dehumidifying efficiency of the drying module and the dehumidifying effect of the clothing treatment equipment using this solution.

[0065] Furthermore, to better explain the technical solution of the present application, as shown in Figures 17 and 18, Figure 17 shows more detailed marks of the moisture absorption and desorption member 3, and Figure 18 shows the correspondence between the areas of the turntable 200 and the moisture absorption area 1-1, regeneration area 1-2, and cooling area 33 of the moisture absorption and desorption member 3.

[0066] Specifically, the moisture absorption and desorption member 3 includes a turntable 200, a turntable housing 411, and an isolation plate 4. The turntable housing 411, the turntable 200, and the isolation plate 4 are surrounded by each other to form a moisture absorption region 1-1, a regeneration region 1-2, and a cooling region 33, which are independent of each other. The moisture absorption and desorption member 3 will be further described below. The turntable 200 is used to adsorb moisture in a humid airflow and to discharge the adsorbed moisture by heating. The regions of the turntable 200 correspond to the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33. An adsorption medium is installed on the turntable 200. The adsorption medium may be a moisture absorbent for absorbing moisture, and can absorb moisture in the air and release the adsorbed moisture when heated.

[0067] The adsorption medium may be various media, such as, but not limited to, zeolite (molecular sieve), alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, etc. In the case of solid moisture absorbents, such as zeolite (molecular sieve), alkali metal aluminosilicate (13X molecular sieve), lithium chloride, modified silica gel, activated alumina, etc., a heating assembly can be used to desorb moisture from the moisture absorbent. The heating assembly may include, but is not limited to, an element with a heating function, such as a heating wire or heater.

[0068] The turntable housing 411 surrounds the turntable 200, and the separator 4 is located within the turntable housing 411. The turntable housing 411, the turntable 200, and the separator 4 together form the mutually independent dehumidification zone 1-1, the regeneration zone 1-2, and the cooling zone 33. The turntable 200 contains the adsorption medium described above. The adsorption medium adsorbs moisture in the air, while a driving member such as a drive motor or gear drives the rotation of the turntable 200, further rotating the turntable 200. The adsorption medium in the corresponding moisture absorption zone 1-1 of the turntable 200 absorbs moisture in the air and dries the air, thereby providing dry air. Driven by the driving member, the turntable 200 rotates, transferring the adsorption medium after adsorption from the moisture absorption zone 1-1 to the regeneration zone 1-2. The temperature of the adsorption medium in the regeneration zone 1-2 is higher than that of the adsorption medium in the moisture absorption zone 1-1. The moisture absorbing and desorbing member 3 raises the temperature of the regenerating region 1-2 by various methods, such as heating, and discharges moisture from the adsorption medium in the regenerating region 1-2. In one embodiment, a heater can be used to blow hot air from a fan, and as the hot air passes through the adsorption medium in the regenerating region 1-2, the temperature of the adsorption medium in the regenerating region 1-2 can be raised. In other words, the heating discharges moisture from the adsorption medium in the regenerating region 1-2 on the turntable 200. The moisture absorbing and desorbing member 3 further removes the released moisture from the regenerating region 1-2. For example, the moisture is removed from the regenerating region 1-2 by various methods, such as using a fan to discharge moisture through an air exhaust pipe.

[0069] In one embodiment, the air circuit of the regeneration zone can be configured so that the moisture released from the regeneration zone (1-2) passes through the regeneration fan and is discharged through the ventilation duct, or passes through the regeneration fan and then through the condenser to condense the air before entering the cooling zone (33), or merges with the circulating air, or is discharged elsewhere. Those skilled in the art can reasonably configure the system according to actual needs. The rotating disk (200) continues to rotate when the power member is driven, and the adsorption medium in the regeneration zone (1-2) enters the cooling zone (33). The moisture absorption and desorption element (3) can use various methods to reduce the temperature of the adsorption medium in the cooling zone (33) and improve the dehumidification capacity of the moisture absorption and desorption element. For example, when the air passes through the adsorption medium in the cooling zone (33), the gas flow can be used to carry away heat from the adsorption medium in the cooling zone (33), further reducing the temperature of the adsorption medium in the cooling zone (33) and improving the dehumidification capacity of the moisture absorption and desorption element. Alternatively, a low-temperature airflow may be introduced into the cooling region 33, and the temperature of the adsorption medium in the cooling region 33 may be reduced when the low-temperature airflow passes through the adsorption medium in the cooling region 33. Furthermore, the temperature of the adsorption medium in the cooling region 33 may be reduced by adding a refrigeration device, etc. Those skilled in the art may install the device according to their actual needs, and the present disclosure does not limit the scope of the present disclosure.

[0070] The turntable housing 411 surrounds the turntable 200, and as shown in FIG. 17, the turntable housing 411 is provided on the outside of the turntable 200. The separator 4 is located inside the turntable housing 411. The separator 4 allows the spaces of the moisture absorption region 1-1, the regeneration region 1-2, and the cooling region 33 to be isolated from one another. Therefore, the gases therebetween do not affect each other. For example, the moisture absorption region 1-1 and the cooling region 33 do not affect the airflow in their own regions because the regeneration region 1-2 has a constant high-temperature airflow. Furthermore, there is no problem of gas mixing when arranging the air circuits, making it easier to arrange the air circuits.

[0071] The turntable housing 411, the turntable 200, and the separator 4 are surrounded by each other to form the mutually independent dehumidification area 1-1, the regeneration area 1-2, and the cooling area 33. The turntable housing 411, the turntable 200, and the separator 4 are surrounded by each other to form three mutually independent spaces, namely the moisture absorption area 1-1, the regeneration area 1-2, and the cooling area 33. The three areas are relatively closed, and their air circuits do not affect each other, so the arrangement of the air circuits does not result in a reduction in dehumidification efficiency due to the problem of gas mixing.

[0072] The temperature of the airflow passing through the cooling zone 33 can be reduced to reduce the temperature of the adsorbent material in the cooling zone 33. Generally, the temperature of the outdoor air is lower than the temperature of the airflow in the laundry treatment container. Therefore, in one embodiment of the present application, an open-circuit airflow design can be implemented, in which external air is introduced into the cooling zone 33 to reduce the temperature of the airflow in the cooling zone 33. In this case, the cooling zone 33 is connected to the outside, and the cooling zone 33 uses the external air to reduce the temperature of the cooling zone 33.

[0073] In one embodiment, it may include a first ventilation path, one end of which is connected to the cooling area 33 and the other end of which is connected to the outside, so that the flow of outside air enters the cooling area 33 along the first ventilation path and reduces the temperature of the cooling area 33.

[0074] Furthermore, to increase the ventilation speed, as shown in FIG. 17 , a second fan 8 is further included in the first ventilation path. This fan is used to increase the gas flow rate between the cooling zone 33 and the outside air or to increase the rate at which the temperature of the cooling zone 33 decreases. The second fan 8 can increase the airflow rate and remove the heat from the adsorption medium as the air passes through the adsorption medium in the cooling zone 33. This can reduce the temperature of the cooling zone 33. In one embodiment provided by the present application, the second fan 8 is a regenerative fan, i.e., reusing the regenerative fan can effectively reduce production costs. If cost is not a consideration, the second fan 8 can be a refrigeration fan, which can not only increase the airflow rate but also reduce the temperature of the airflow. This can effectively increase the rate at which the temperature of the cooling zone 33 decreases, thereby achieving the goal of reducing the temperature of the cooling zone 33.

[0075] A condenser may be further provided to reduce the temperature of the airflow passing through the cooling zone 33, and the airflow passes through the condenser before entering the cooling zone 33, thereby reducing the temperature of the adsorption medium in the cooling zone 33. Therefore, in one embodiment provided by the present application, as shown in Figures 19 and 20, a first condenser 7 is further provided, located upstream of the inlet of the cooling zone 33, to reduce the temperature of the airflow passing through the first condenser 7 and entering the cooling zone 33.

[0076] 19 is a structural schematic diagram of the first condenser 7, and FIG. 20 is a schematic diagram of the current location of the first condenser 7. The first condenser 7 is located in the air circuit of the entrance cooling area 33, so that the temperature of the air entering the cooling area 33 can be reduced, and therefore the first condenser 7 is located upstream of the intake port of the cooling area 33.

[0077] FIG. 21 is a schematic diagram of the upper housing of a drying module. The upper housing in FIG. 21 corresponds to the lower housing in FIG. 16 and can be combined to form a complete drying module. The airflow can be dry airflow discharged from the exhaust port of the moisture absorption area 1-1. Based on this design, the air circuit can be designed as a closed circuit structure. As described in the previous embodiment, the airflow entering the cooling area 33 is external air, i.e., an open circuit structure. In practice, a closed circuit structure can also be designed. Compared with an open circuit structure, a closed circuit structure has the following advantages: first, it can effectively save space when the installation space of the laundry treatment equipment is limited; and second, it can omit the design of the device for filtering external gas. When the air circuit is an open circuit design, the part that filters the gas needs to be considered. In addition to determining the design of the intake volume and the size of the intake port, it is necessary to ensure that dust does not get mixed into the gas and affect the effectiveness of the turntable. This design involves some design challenges, and dust must also be periodically cleaned to prevent the turntable's service life from being affected. Therefore, a closed-circuit airflow design can eliminate the need for external gas filtering devices. This eliminates the need for additional air filtering components, effectively controlling product costs and extending the product's service life. In contrast, a closed-circuit design places high demands on designers. Achieving a closed-loop airflow circuit by rationally utilizing limited space and arranging various fans is a technical problem to be solved. Based on prior art, the design of a closed-circuit airflow circuit must focus on the placement of the closed-circuit airflow. Fans and other devices can be used to accelerate the airflow, achieving a closed-loop airflow circuit design. In the airflow layout of the embodiments of this application, fans are used. This will not be discussed further below.

[0078] When the first condenser 7 is located upstream of the air intake of the cooling zone 33, a specific embodiment thereof may be as follows: When the airflow enters the regeneration zone 1-2 and the cooling zone 33, the heated airflow from the regeneration zone 1-2 and the airflow from the cooling zone 33 enter the first condenser 7 together, and after being cooled by the first condenser 7, the cooled and dehumidified airflow passes through the fan and returns to the regeneration zone 1-2 and the cooling zone 33, where it is blown against the cooled airflow to lower the temperature of the cooling zone 33. That is, the airflow in the regeneration zone 1-2 (i.e., the moisture-releasing airflow) is heated by a heater and then dehumidifies the regeneration zone 1-2, while the airflow entering the cooling zone 33 does not need to be heated and directly enters the cooling zone 33 to lower its temperature. Alternatively, the following may be used. The dry airflow from the moisture absorption region 1-1 after dehumidification is either directly discharged into the cooling region 33 to lower its temperature, or the dry airflow from the moisture absorption region 1-1 after dehumidification is passed through a condenser and then discharged into the cooling region 33 to lower its temperature. Therefore, the drying module further includes a second ventilation path having one end communicating with the exhaust port of the regeneration region 1-2 and the other end communicating with the intake port of the cooling region 33, and a first condenser 7 located in the second ventilation path. In this case, the exhaust port of the regeneration area 1-2 is connected to the intake port of the cooling area 33, and the first condenser 7 is located in the second ventilation path, i.e., the air discharged from the regeneration area 1-2 is condensed by the first condenser 7 before entering the cooling area 33, or the first condenser 7 is located between the exhaust port of the moisture absorption area 1-1 and the intake port of the cooling area 33, and the air is first condensed before entering the cooling area 33, and then enters the cooling area 33, thereby further realizing the above technical solution.

[0079] The above technical solution may be as follows: the drying module further includes a third ventilation path, one end of which is connected to the exhaust port of the moisture absorption region 1-1 and the other end of which is connected to the intake port of the cooling region 33, and the cooling region 33 uses the airflow discharged from the moisture absorption region 1-1 and introduced along the third ventilation path to reduce the temperature of the cooling region 33.

[0080] The above technical solution may be as follows: The dry airflow discharged from the moisture absorption region 1-1 directly enters the cooling region 33, and uses the air flow to carry away heat from the cooling region 33, thereby further reducing the temperature of the cooling region 33. Alternatively, the solution may be as follows: The low-temperature dry airflow generated after the dry airflow discharged from the moisture absorption region 1-1 passes through the first condenser 7 enters the cooling region 33, thereby further improving the condensation effect of the cooling region 33. Alternatively, the solution may be as follows: The airflow discharged from the regeneration region 1-2 is condensed by the first condenser 7 and then enters the cooling region 33.

[0081] Specifically, the air circuit is configured so that moist air flows out of the exhaust port of the laundry treatment container 1, passes through a circulation fan, and splits into two paths. One airflow enters the moisture absorption zone 1-1 via the circulation air circuit and is discharged into the laundry treatment container 1 after dehumidification. The other airflow enters the cooling zone 33 via the cooling air circuit, where it is heated by a regeneration heater and then enters the regeneration zone 1-2 to desorb moisture from the rotating disk. The moist, high-temperature airflow enters the condenser and is condensed. The resulting, relatively dry, low-temperature airflow is blown by a fan into the regeneration zone 1-2 and the cooling zone 33. One airflow is reheated by the heater and condensed, and the other airflow from the cooling zone 33 enters a zone other than the regeneration zone 1-2, such as the moisture absorption zone 1-1, the drum, or the indoor air. A second condenser may be added to lower the temperature of the cooling zone 33. Therefore, the cooling area 33 further includes a second condenser 6 for reducing the temperature of the cooling area 33. When the heater of the regeneration area 1-2 and the cooling area condenser of the cooling area 33 are installed on the upper part of the turntable 200, a device and one air inlet may be installed on the upper part of the turntable 200, and one air flow passes through the heater to enter the regeneration area 1-2, then passes through the condenser, and is heated again before entering the regeneration area 1-2, forming a closed loop, and the other air flow enters the cooling area 33, passes through the cooling device, and then merges with the circulating air flow.

[0082] The refrigeration method of the second condenser is at least one of water cooling, air cooling, and semiconductor refrigeration. As shown in Figure 22, referring to the above-mentioned embodiment, when the second condenser 6 is located in the cooling area 33, the low temperature generated by the second condenser 6 can be used to lower the temperature of the cooling area 33, which is suitable for situations where the space is limited. Therefore, in actual application scenarios, an appropriate second condenser 6 can be selected, the location of the second condenser 6 can be determined, and an appropriate refrigeration method can be determined according to actual needs.

[0083] The drying module is provided with a dehumidifying gas path and a functional device accommodating area. The functional device may include a heating device and a cooling device, which may be integrated or installed separately. The heater may be a heating tube, a heating wire, or a semiconductor heating element. The cooler may be air-cooled. If the cooler is air-cooled, there may be no device, or a cooling method such as installing a fan or installing a semiconductor cooling element. The heating device and cooling device may be installed above or below the turntable 200, as long as they are compatible with the turntable 200.

[0084] As shown in FIG. 22, for example, the regenerating zone 1-2 has a heater. The heater has only some heating pipes, and the cooling zone 33 has no heating pipes or other cooling devices such as a small fan or semiconductor refrigeration device. The regenerating zone 1-2 and the cooling zone 33 have a separator 4. If the cooling zone 33 does not have a cooling device, the cooling zone 33 can achieve the cooling effect by using the airflow after condensation to remove heat from the cooling zone 33. The cooling zone 33 can also have a cooling device added, as shown in FIG. 22. The cooling device may be at least one of water cooling, air cooling, and semiconductor refrigeration.

[0085] If the second condenser 6 of this technical solution is water-cooled, the airflow discharged from the cooling zone 33 can be reused. The airflow passing through the second condenser 6 can enter the moisture absorption zone 1-1 to improve the condensation dehumidification effect of the moisture absorption zone 1-1. Alternatively, if no refrigeration device is installed in the cooling zone 33, i.e., if a technical solution is used in which the airflow carries away heat from the cooling zone 33, the discharged airflow can be reused as the airflow at the exhaust port of the regeneration zone 1-2, thereby realizing the circulation of a closed air circuit. Those skilled in the art can reasonably configure the system according to actual needs. If the refrigeration method of the second condenser 6 is air-cooled, the second condenser 6 can be air-cooled by a conventional fan or can even be a refrigeration fan. That is, the airflow generated by the conventional fan is a low-temperature airflow, which can enter the intake port of the cooling zone 33 to lower the temperature of the cooling zone 33 and improve the dehumidification capacity of the turntable 200.

[0086] The second condenser 6 in the technical solution of this embodiment can also be reused, and the number of the second condenser 6 can be multiple according to actual needs. Those skilled in the art can reasonably configure it according to actual needs, and no further details are provided here. The refrigeration method of the second condenser 6 can be semiconductor refrigeration.

[0087] To more clearly explain the technical solutions of the embodiments of this application, a brief description of semiconductor refrigeration follows. A semiconductor refrigerator, also known as a thermoelectric refrigerator, is a device that generates cooling energy by utilizing the thermoelectric effect of semiconductors. When a conductor is used to connect two dissimilar metals and a direct current is passed through it, the temperature of one junction decreases and the temperature of the other junction increases. Reverse power supply causes the temperature of the junctions to change in the opposite direction. This phenomenon is called the Peltier effect or thermoelectric effect. The thermoelectric effect of pure metals is very small, but using N-type and P-type semiconductors instead of metals significantly improves the effect. After power is applied, electron-hole pairs are generated near the upper junction, reducing the internal energy and temperature, and absorbing heat from the outside. This is called the cold end. At the other end, the internal energy increases due to recombination of the electron-hole pairs, increasing the temperature and releasing heat to the environment. This is called the hot end. Both the temperature difference and cooling energy generated by a pair of semiconductor thermoelectric elements are very small. A practical semiconductor refrigerator, also known as a thermopile, consists of multiple pairs of thermoelectric elements connected in parallel or series. A single-stage thermopile can achieve a temperature difference of approximately 60°C, i.e., the cold end temperature can reach -10 to -20°C. Increasing the number of thermopile stages can increase the temperature difference between the two ends. However, it is preferable not to have too many stages, and two to three stages are generally used. Generally, semiconductor refrigerators have good refrigeration effects and do not require too much space, but they require relatively high power consumption. Therefore, those skilled in the art can select the appropriate refrigeration unit based on their actual needs.

[0088] Of course, the second condenser 6 can be multiple, and multiple refrigeration methods can be used in the same laundry treatment equipment, such as semiconductor refrigeration and air cooling simultaneously, or semiconductor refrigeration, air cooling, and water cooling simultaneously. Reasonable selection can be made based on the current application scenario. When using the above technical solution, the air circuit arrangement can be as follows: The humid airflow can be split into two paths after exiting the exhaust duct through the fan, or it can be split into two paths after entering the exhaust port of the laundry treatment container 1. A cooling path, such as water or air cooling, is installed in the exhaust duct. The airflow is cooled through the cooling path before entering the cooling zone 33, improving the cooling efficiency of the cooling zone 33. At the same time, the filter mesh self-cleaning drainage path can be reused for pre-condensation in the exhaust duct, further improving dehumidification efficiency.

[0089] Optionally, the drying module further includes a fourth ventilation path, one end of which is connected to the exhaust port of the cooling zone 33 and the other end of which is connected to the intake port of the regeneration zone 1-2, so that the airflow discharged from the cooling zone 33 enters the regeneration zone 1-2 along the fourth ventilation path. The airflow discharged from the exhaust port of the cooling zone 33 has a predetermined temperature of the cooling zone 33. Therefore, the temperature of the airflow discharged from the exhaust port of the cooling zone 33 is higher than the temperature of the air at the intake port of the cooling zone 33, and the air from the cooling zone 33 can be directly discharged into the drum (clothes treatment container 1). To save energy, the air from the cooling zone 33 can also be discharged into the regeneration zone 1-2.

[0090] The regeneration zone 1-2 uses heating to remove moisture from the rotating disk 200 and restore its moisture absorption capacity. Therefore, the airflow entering the regeneration zone 1-2 is usually heated, and when the airflow enters the regeneration zone 1-2, it is usually heated by a device such as a regeneration heater. Therefore, in the embodiment of the present application, when designing a closed-loop air circuit, the airflow discharged from the exhaust port of the cooling zone 33 is sent to the regeneration heater by the action of a fan and then enters the regeneration zone 1-2, thereby reducing some energy consumption. Taking advantage of the fact that the temperature of the airflow discharged from the cooling zone 33 is high, this part of the airflow is sent to the regeneration zone 1-2.

[0091] The technical solution of the embodiment of the present application utilizes the temperature of the airflow discharged from the cooling region 33 and reuses it in the regeneration region 1-2, and the airflow that needs to be heated in the regeneration region 1-2 is used to discharge moisture from the turntable 200 and restore its moisture absorption capacity. Therefore, the recycled airflow can appropriately reduce the energy consumption required for the airflow that needs to be heated, saving energy. Furthermore, the temperature of the airflow discharged from the cooling region 33 is reused in the regeneration region 1-2, relatively increasing the temperature of the regeneration region 1-2. Therefore, the heating effect of the regeneration region 1-2 is improved, and by improving the heating effect, moisture in the turntable 200 can be discharged relatively quickly, thereby improving the moisture absorption capacity of the turntable 200.

[0092] As shown in FIG. 27, the drying module includes a turntable housing 411 having a heater mounting portion installed therein and accommodating a moisture absorbing and releasing member, a heating device 30 mounted on the heater mounting portion, and a hollow annular sealing assembly 50 installed between the heating device 30 and the turntable housing 411, wherein a first sealing body 521 contacts the heating device 30 and a second sealing body 522 contacts the turntable housing 411.

[0093] In some embodiments, the turntable housing 411 containing the moisture absorption and dehumidification member may have a circular structure, and a moisture absorption region and a dehumidification region may be provided on the turntable housing 411. The moisture absorption region and the dehumidification region are separated by at least two radially arranged ribs on the turntable housing 411. A heater mounting portion is provided in the dehumidification region of the turntable housing 411 to facilitate modular assembly of the heating device 30. The shape of the heating device 30 matches the shape of the dehumidification region, and the dehumidification region is a fan-shaped region. In this case, the heating device 30 has a fan-shaped structure. The heating device 30 may include a space formed by a top wall and two radial side walls, an inner arc-shaped side wall and an outer arc-shaped side wall, and the heating member is provided in the space. The bottom of the heating device 30 may be hollow, and an air inlet may be provided on the outer arc-shaped side wall so that dry, low-temperature regeneration air enters through the air inlet, is heated by the heating element, and then flows downward through the moisture absorption and dehumidification member. The moisture absorption and desorption member may include a turntable that absorbs moisture in the wet circulating airflow from the drum in the moisture absorption region and converts the wet circulating airflow into a dry circulating airflow. The dry circulating airflow enters the drum through the drum air inlet and fully contacts the clothes, improving drying efficiency and reducing energy consumption. The turntable is rotatable relative to the turntable housing 411. When the turntable rotates to the dehumidifying region, the regenerated hot airflow desorbs moisture from the portion of the turntable located in the dehumidifying region. Thus, the turntable circulates through the moisture absorption and dehumidifying regions during its circumferential rotation, continuously absorbing and desorbing moisture. This ensures that the turntable always has good moisture absorption capacity, thereby improving the efficiency and effectiveness of the turntable moisture absorption. The sealing assembly is located between the heating device 30 and the turntable housing 411. To allow the regenerated hot airflow to pass smoothly, the sealing assembly is shaped like a hollow ring. The shape of the sealing assembly is compatible with the heating device 30 and the turntable housing 411 to facilitate assembly. The sealing assembly 50 may include a support member 51 and a sealing pad 52. The support member 51 is configured in an L-shaped configuration along a cross section tangent to the length of the support member 51.The sealing pad 52 includes a first sealing body 521 and a second sealing body 522, respectively installed on both sides of the L-shaped structure. A portion of the support member 51 is exposed to the outside of the sealing pad 52, and the exposed portion of the support member 51 contacts the regenerated hot airflow to prevent the high temperature of the regenerated hot airflow from being directly transmitted to the sealing pad 52. The sealing pad 52 can be made of a foam material, a silica gel material, or a soft rubber material. A preferred sealing pad 52 is made of a silica gel material. This allows the sealing pad 52 to remain soft and elastic at both high and low temperatures, providing good sealing performance. The support member 51 can be made of an insulating material or a metal material. A preferred support member 51 is an ordinary carbon steel plate metal member. This not only improves the strength of the support member 51, but also provides a certain level of insulation. The L-shaped cross section of the support member 51 improves the strength of the support member 51 and facilitates the installation of the second sealing body 522 and the first sealing body 521 on the inner and outer surfaces of the L-shaped structure. For example, the first sealing body 521 contacts the heating device 30, the second sealing body 522 contacts the turntable housing 411, and the support member 51 is positioned between the first sealing body 521 and the second sealing body 522. This buffers the heat generated by the heating device 30 and prevents direct transmission of high temperatures to the turntable housing 411, which could damage it. This delays aging of the turntable housing 411 and extends the service life of the drying module. Furthermore, the heat generated by the heating device 30 heats the regenerated airflow to desorb moisture from a portion of the moisture absorption / desorption member, thereby generating a regenerated hot airflow. The first sealing body 521 may not be installed on the outside of the bent portion of the support member 51 but may be exposed to the outside of the sealing pad 52, and the exposed portion may come into contact with the regenerated hot air flow to prevent the high temperature of the regenerated hot air flow from being directly transmitted to the second sealing body 522 installed on the inner surface of the L-shaped structure.The second sealing body 522 seals around the heater mounting portion of the turntable housing 411 to prevent leakage of the regenerated hot airflow, thereby improving the drying efficiency of the drying module.

[0094] In some examples, the sealing assembly of the drying module includes a support member 51 and a sealing pad 52, as shown in FIGS. 23-26. At least a portion of the support member 51 has an L-shaped structure, i.e., the support member 51 can be configured in an L-shaped structure along a cross section tangent to the length of the support member 51. The sealing pad 52 includes a first sealing body 521 and a second sealing body 522, respectively, installed on either side of the L-shaped structure. At least a portion of the support member 51 is exposed to the sealing pad 52, and the exposed portion of the support member 51 contacts the regenerated hot air stream to prevent the high temperature of the regenerated hot air stream from being directly transmitted to the sealing pad 52. The sealing pad 52 can be made of a foam material, a silica gel material, or a soft rubber material. A preferred sealing pad 52 is made of a silica gel material. In this way, the sealing pad 52 remains soft and elastic at both high and low temperatures, providing good sealing performance. The support member 51 may be made of an insulating material or a metal material. A preferred support member 51 is a conventional carbon steel plate metal member. This not only improves the strength of the support member 51 but also provides a certain degree of thermal insulation. The L-shaped cross section of the support member 51 not only improves the strength of the support member 51 but also facilitates the installation of the second sealing body 522 and the first sealing body 521 on the inner and outer surfaces of the L-shaped structure. For example, the first sealing body 521 contacts the heating device 30, the second sealing body 522 contacts the turntable housing 411, and the support member 51 is positioned between the first sealing body 521 and the second sealing body 522. This buffers the heat generated by the heating device 30 and prevents high temperatures from being directly transmitted to the turntable housing 411, thereby preventing damage. This delays the aging of the turntable housing 411 and extends the service life of the drying module. Furthermore, in order to desorb moisture from a part of the moisture absorbing and releasing member, the heat generated by the heating device 30 heats the regenerated airflow, thereby obtaining a regenerated hot airflow.The first sealing body 521 may not be installed on the outside of the bent portion of the support member 51, but may be exposed to the outside of the sealing pad 52, and this exposed portion may come into contact with the regenerative hot air stream to prevent the high temperature of the regenerative hot air stream from being directly transmitted to the second sealing body 522 installed on the inner surface of the L-shaped structure. To prevent leakage of the regenerative hot air stream, the second sealing body 522 seals the periphery of the heater mounting portion of the turntable housing 411, thereby improving the drying efficiency of the drying module.

[0095] In some embodiments, the support member 51 includes a first side 511 and a second side 512 connected to the first side 511 to form an L-shaped structure, with a portion of the side of the first side 511 or the second side 512 exposed to the sealing pad 52. Specifically, the support member 51 can be punched using a conventional carbon steel sheet metal member. In this way, even if the thickness of the support member 51 is as thin as possible, it can achieve a certain strength and rigidity and can withstand the impact of the high-speed flow of the regenerated hot air, thereby increasing the durability of the sealing assembly and reducing manufacturing costs. For example, a portion of the outer surface of the second side 512 is exposed to the sealing pad 52, and the exposed portion comes into contact with the regenerated hot air to prevent the high temperature of the regenerated hot air from being directly transmitted to the second sealing body 522 installed on the inner surface of the second side 512. The second sealing body 522 seals around the turntable housing 411 to prevent leakage of the regenerated hot airflow, thereby improving the drying efficiency of the drying module.

[0096] In some embodiments, at least a portion of the first sealing body 521 covers one side of the first side 511 or the second side 512, and at least a portion of the second sealing body 522 covers the other opposite side of the first side 511 or the second side 512. For example, the second sealing body 522 may be installed on the inner surface of the L-shaped structure, and the first sealing body 521 may be installed on the outer surface thereof. The first sealing body 521 may contact the heating device 30, and the second sealing body 522 may contact the turntable housing 411.

[0097] In some embodiments, the first sealing body 521 is provided with a protrusion 523 extending toward one side away from the second sealing body 522. The provision of the protrusion 523 facilitates contact with the heating device 30, and the deformation of the protrusion 523 can provide a good bond to the heating device 30 to ensure the airtightness of the system.

[0098] In some embodiments, the protrusion 523 includes a first sealing strip and a second sealing strip symmetrically spaced apart from the first sealing strip, where the first sealing strip and the second sealing strip are both inclined, and the spacing between the first sealing strip and the second sealing strip gradually increases in a direction away from the first sealing body 521 and the second sealing body 522. The first sealing strip and the second sealing strip may be inclined and spaced apart from the first sealing body 521. When the sealing assembly is tightly attached to the heating device 30, the first and second sealing strips are deformed and tightly attached to the heating device 30, and the first and second sealing strips are both inclined away from the first sealing body 521, and the gap between the first and second sealing strips gradually increases. Thus, two sealing connections can be formed between the first and second sealing strips and the heating device 30, further ensuring the airtightness of the system.

[0099] In some embodiments, the connection between the first side 511 and the second side 512 is an arc transition, and the angle between the first side 511 and the second side 512 is set to be greater than 90 degrees. This improves the strength of the support member 51, further improving the overall strength of the sealing assembly and the durability of the sealing assembly. In some embodiments, the end face of the second sealing body 522 protrudes from the first side 511 or the second side 512. For example, the second sealing body 522 may be installed slightly higher than the second side 512, and the end face of the second sealing body 522 may contact the moisture absorbing and desorbing member to ensure airtightness of the system.

[0100] In some embodiments, a mounting plate 55 may be provided extending outward from the first side 511, and a first mounting hole may be provided in the mounting plate 55. A matching second mounting hole may be provided at a location corresponding to the heating device 30 and the turntable housing 411. Threaded fasteners may pass through the first and second mounting holes to facilitate assembly of the sealing assembly with the heating device 30 and the turntable housing 411.

[0101] In some embodiments, the support member 51 and the sealing pad 52 are processed into an integrated structure, or the first sealing body 521 and the second sealing body 522 are connected into an integrated structure. A groove is formed between the first sealing body 521 and the second sealing body 522, and the first edge 511 or the second edge 512 is interference-fitted into the groove. For ease of installation, the support member 51 and the sealing pad 52 can be processed into an integrated structure. The support member 51 and the sealing pad 52 can also be provided as a split structure. A groove is formed on the inner side of the sealing pad 52, and the first edge 511 of the support member 51 is inserted into the groove, and the support member 51 is tightly attached to the sealing pad 52 to complete the assembly.
