[0002] The present application relates to the field of home appliance manufacturing technologies, and in particular, to a heating device, a drying module, and a clothing treatment apparatus.BACKGROUND

[0003] With the improvement of people's living standards, as well as the continuous advancement of technology and product performance, there are increasing demands on functions of household appliances to meet the growing needs for use in homes and to reduce manual labor. For clothes washing, which is one of the most time-consuming manual labors in homes, the entire clothes-washing process involves necessary steps such as washing, airing, and storage. Conventional washing machines can only perform a washing function, and manual efforts are still required for airing, drying, and storage. Newly introduced integrated washer-dryer machines in the industry combine washing and drying functions, which can be activated with one button and dry the clothes after the washing is completed, thereby greatly saving labor costs for airing and storage.

[0004] The inventors have found that in the current integrated washer-dryer machine, moisture in a wet airflow discharged from a drum is adsorbed by a rotating wheel, and the moisture is desorbed from the rotating wheel by using a heating unit. Typically, the temperature of the heating unit cannot be regulated, and an excessively high temperature of the heating unit is likely to cause high power consumption and energy consumption, and an excessively low temperature of the heating unit may lead to low moisture adsorption efficiency of the rotating wheel and a long drying time.SUMMARY(I) Object of Application

[0043] In order to better understand the foregoing technical solutions, the technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and specific features in the embodiments are detailed descriptions of the technical solutions in the embodiments of the present application, but are not intended to limit the technical solutions in the present application. The embodiments of the present application and the technical features in the embodiments may be combined with each other with no conflict.

[0044] For clearer descriptions of the objectives, technical solutions, and advantages of the present application, the present application is described in further detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present application. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present application. According to a first aspect of the present application, a heating device is provided. As shown in FIGS. 1-4, the heating device includes: a heater housing 11, a heater, and a temperature regulator 12. An accommodating space is provided at an inner side of the heater housing 11. The heater is provided in the accommodating space. The temperature regulator 12 is provided at an outer side of the heater housing 11, an end portion of the heater extends to the outer side of the heater housing 11, and the temperature regulator 12 is connected to the heater to regulate the operating temperature of the heater. The power of the heater can be regulated by the temperature regulator 12 to increase or decrease the operating temperature of the heater. A dry low-temperature airflow is introduced into the accommodating space of the heater housing 11, and the dry low-temperature airflow exchanges heat with the heater, such that the dry low-temperature airflow is heated and turned into a dry high-temperature airflow. A moisture adsorption-desorption member includes a rotatable rotary disk, and at least a part of the moisture adsorption-desorption member can adsorb moisture in a wet circulating airflow from a drum during use. The heater is arranged in close proximity to the other part of the rotary disk, and the dry high-temperature airflow desorbs moisture from the other part of the rotary disk, such that the dry high-temperature airflow is turned into a hot and wet airflow.

[0045] The airflow in the accommodating space is heated and then used to desorb moisture from the other part of the rotary disk, such that the moisture adsorption capacity of the rotary disk can be restored and the rotary disk can be used repeatedly. Therefore, the airflow in the accommodating space can be defined as a regeneration airflow. The temperature regulator 12 is provided at the outer side of the heater housing 11, which can prevent the temperature regulator 12 from being damaged due to its position in a high-temperature and humid environment for a long time. In addition, a temperature detector may be provided in the accommodating space to detect the temperature of the regeneration airflow in the accommodating space. When the clothing treatment apparatus performs the dehydration or drying process, the power of the heater can be regulated up by the temperature regulator 12 if the detected temperature of the regeneration airflow is too low, so as to increase the operating temperature of the heater and increase the heating temperature of the regeneration airflow. The power of the heater can be regulated down by the temperature regulator 12 if the detected temperature of the regeneration airflow is too high, so as to reduce the operating temperature of the heater and reduce the heating temperature of the regeneration airflow. In this way, the moisture adsorption efficiency of the rotary disk can be improved, the drying time can be reduced, and energy can be saved.

[0046] In some embodiments, the temperature regulator is configured as a temperature controller to control on-off of the heater; and / or the temperature regulator is configured as a silicon controlled rectifier to regulate the power of the heater. When the temperature regulator is configured as the silicon controlled rectifier, the power / temperature of the heater can be regulated. Through the control of signal inputs, the silicon controlled rectifier (thyristor) module connected in series in the main circuit is controlled to change on and off of the voltage in the main circuit, thereby implementing control on the heater. By adding a pulse with the same period as the current to a trigger electrode of the silicon controlled rectifier, the silicon controlled rectifier can control an average value of the voltage in the rectifier circuit according to a change in a phase difference between the pulse and the current, such that the temperature of the heater can be regulated. When the temperature regulator is configured as the temperature controller, the heater is disconnected when the operating temperature of the heater is abnormal (such as when the temperature is too high); and when the temperature returns to normal, the heater can be connected manually or automatically.

[0047] If the heater housing 11 is made of a stainless steel material, when its structure is complex and the heater housing 11 is drawn by stamping to form the recessed accommodating space for mounting the heater, the stainless steel material is not easy to draw and cracking and wrinkling defects may occur during drawing. The wrinkling and cracking of the heater housing 11 may lead to poor sealing and an increase in the failure rate of the heating device, which is likely to cause an increase in the overall cost. In view of this, in some embodiments, the heater housing 11 is of an integrated structure formed by casting aluminum. The heater housing 11 is made of aluminum alloy by die casting, such that the heater housing 11 of a complex structure can be manufactured, and the manufacturing process is simple and the processing cost is low. Cracking is unlikely to occur when the recessed accommodating space is drawn, and the end surface of the heater housing 11 is flat and unlikely to wrinkle, such that the yield rate of the heating device can be improved, the manufacturing cost can be reduced, and the sealing performance of the end surface can be improved.

[0048] In some embodiments, the heater housing 11 includes a base 111, a top wall 112, and a side wall 113 protruding from the top wall 112. The top wall 112 and the side wall 113 form the accommodating space in an enclosing manner, the base 111 is arranged along a periphery of the side wall, and the base extends outward away from the accommodating space. The top wall and the side wall are enclosed to form the recessed accommodating space, the heater is mounted in the accommodating space, and the bottom of the heater housing 11 is empty, such that the heater housing can be in communication with another part of the rotary disk when the heater housing is arranged in close proximity to the other part of the rotary disk. The base 111 can be connected and fixed to the rotary disk and the heater housing, the bottom surface of the base can be manufactured into a flat end surface, and a sealing gasket can be used when the base is sealed with the rotary disk and the heater housing, so as to improve the sealing performance. For lightweight design, criss-cross ribs may be provided at the outer side of the top wall 112, and a rib plate may be provided between the side wall 113 and the base 111 to improve the overall strength of the heater housing 11.

[0049] In some embodiments, the heater housing 11 is of a sector-shaped structure; and the side wall 113 includes two second side walls arranged along a radial direction of the sector, a first side wall, and a third side wall. Both ends of the first side wall and the third side wall are connected to the two second side walls, and the length of the first side wall is larger than that of the third side wall, where the first side wall is arranged along an outer arc of the sector, and an air inlet 16 is provided on the first side wall. In this embodiment, it is a preferred solution that the heater housing 11 is of the sector-shaped structure. The heater housing 11 may also be of an irregular structure, which is not limited herein. The heater housing 11 is connected to an upper rotary disk housing 210, such that a moisture adsorption zone and a regeneration zone are separated from each other, i.e., a wet circulating airflow in the moisture adsorption zone can be largely isolated from a regeneration airflow in the regeneration zone.

[0050] In some embodiments, the heating device further includes: an air conditioning plate 13, where the air conditioning plate is provided with air holes 14 that are spaced apart from each other. The air conditioning plate 13 is sector-shaped and arranged in the accommodating space, the air conditioning plate 13 is spaced apart from, and substantially parallel to, the top wall 112, and the air conditioning plate 13 is connected and fixed to the top wall 112 by a connecting member. A gap is formed between the air conditioning plate 13 and the top wall of the heater housing 11 to form an airflow channel; and the airflow channel is in communication with the air inlet 16. The air conditioning plate 13 can be detachably connected to the top wall by threaded fasteners. In order to maintain a certain spacing distance between the air conditioning plate 13 and the top wall, a cushion block can be provided between the air conditioning plate 13 and the top wall. Through the arrangement of the air holes 14, the air intake volume of the regeneration airflow can be regulated, and the regeneration airflow can enter the heater uniformly for heat exchange.

[0051] In some embodiments, the heater includes at least one heating tube or a plurality of heating tubes 15 connected end to end, and the heating tubes 15 are spaced apart from each other along the radial direction of the sector. The length direction of the heating tube 15 is arranged along a direction perpendicular to the radial direction of the sector. An end portion of the heating tube 15 extends from the second side wall to the outer side, the temperature regulator 12 is arranged on the second side wall, and the temperature regulator 12 and the end portion of the heating tube 15 are arranged on the second side wall on the same side, where the temperature regulator 12 is connected to the heating tube 15 to regulate the operating temperature of the heating tube 15. The temperature regulator 12 is provided at the outer side of the heater housing 11, which can prevent the temperature regulator 12 from being damaged due to its position in a high-temperature and humid environment for a long time. The heating tube 15 is distributed in an S-shape, such that the length of the heating tube 15 distributed in the accommodating space can be larger, so as to increase the contact area with the regeneration airflow, thereby achieving a higher heat exchange efficiency with the regeneration airflow.

[0052] In some embodiments, the heating tube 15 is located between the air conditioning plate 13 and the top wall of the heater housing 11; or the air conditioning plate 13 is located between the heating tube 15 and the top wall of the heater housing 11. The air conditioning plate 13 may be arranged upstream or downstream of the heater. Of course, upstream is a preferred choice. The air conditioning plate 13 guides the airflow flowing into the accommodating space of the heater such that the regeneration airflow can fully transfer the heat of the heater to the rotary disk. In this case, the heater is closer to the rotary disk, and the air conditioning plate 13 is spaced apart from the rotary disk. The air conditioning plate 13 may also be arranged downstream of the heater. In this case, the advantage is that the regeneration airflow is in full contact with the heater first, such that the regeneration airflow is uniformly heated, and then the hot airflow flows to the rotary disk through the guidance of the air conditioning plate 13. In this case, the air conditioning plate 13 is arranged adjacent to the rotary disk, and the heater is spaced apart from the rotary disk. In addition to homogenizing the airflow and guidance, the air conditioning plate 13 can protect the heating tube 15 to a certain extent. Alternatively, the air conditioning plate 13 can be omitted, and the regeneration airflow flows directly to the rotary disk after flowing through the heater, thereby saving costs and reducing the complexity of the mechanism.

[0053] In some embodiments, the air holes 14 are arranged in rows, and each row of air holes 14 are positioned corresponding to the position of the heating tube 15. The heating tube 15 is located below the air holes 14; and the axis of the heating tube 15 is offset from the central line of a corresponding row of air holes 14, and the central line of each row of air holes 14 is closer to the air inlet 16 than the axis of the heating tube 15. When the regeneration airflow is blown in from the air inlet 16 of the heater and blows inward along the radial direction of the sector, a speed will be generated along the flow direction of the regeneration airflow. Therefore, by providing some offset for the central line of each row of air holes 14, the regeneration airflow passing through the air holes 14 can directly face the heating tube 15, so as to achieve a higher heat exchange efficiency between the regeneration airflow and the heating tube 15.

[0054] In some embodiments, the heating device further includes: a fixing component 17 provided on the air conditioning plate 13 to fix the position of the heating tube 15, where the fixing component 17 includes a first body and a second body, one side of the first body is connected and fixed to the air conditioning plate 13, and the other opposite side of the first body is provided with at least one first semicircular hole matching with the heating tube 15; the second body is provided with at least one second semicircular hole matching with the heating tube 15; and the first semicircular hole and the second semicircular hole are arranged in pairs. By fixing the heating tube 15 on the air conditioning plate 13 by the fixing component 17, the thickness of the first body can be increased, such that a certain gap is maintained between the heating tube 15 and the air conditioning plate 13 for the regeneration airflow to pass through, thereby achieving a higher heat exchange efficiency between the regeneration airflow and the heating tube 15. The first body and the second body can be provided with the first semicircular hole and the second semicircular hole that are arranged in pairs side by side, and a threaded fastener can be arranged between the first semicircular hole and the second semicircular hole arranged in pairs to clamp the two heating tubes 15 arranged side by side on the fixing component 17 at the same time, achieving a compact structure.

[0055] According to a second aspect of the present application, a drying module is provided. The drying module includes: a moisture adsorption-desorption member, where at least a part of the moisture adsorption-desorption member is configured to adsorb moisture in a wet circulating airflow from a drum; and a heating device, where the heating device is arranged in close proximity to at least another part of the moisture adsorption-desorption member for at least partially removing moisture adsorbed on the at least another part of the moisture adsorption-desorption member. The moisture adsorption-desorption member includes a rotatable rotary disk and a driving assembly, the driving assembly may include a motor, and the motor may drive the rotary disk to rotate. The rotary disk can be made of a material with good moisture adsorption performance, 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 an accommodating cavity of the rotary disk, and the wet circulating airflow in the moisture adsorption zone passes through the rotary disk from bottom to top. The rotary disk adsorbs the moisture in the wet circulating airflow, such that the wet circulating airflow can be turned into a dry circulating airflow. The dry circulating airflow enters the drum through an intake port of the drum and is in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. In the embodiments of the present application, the heating device may include a heater housing 11, a heater, and a temperature regulator 12. A recessed accommodating space is provided in the heater housing 11. The heater is provided in the accommodating space. The temperature regulator 12 is provided at an outer side of the heater housing 11, an end portion of the heater extends to the outer side of the heater housing 11, and the temperature regulator 12 is connected to the heater to regulate the operating temperature of the heater. The power of the heater can be regulated by the temperature regulator 12 to increase or decrease the operating temperature of the heater. A dry low-temperature regeneration airflow is introduced into the accommodating space of the heater housing 11, and the dry low-temperature regeneration airflow exchanges heat with the heater. The heater is configured to heat the regeneration airflow, and the heated regeneration airflow passes through a rotary disk to dehydrate and dry a part of the rotary disk in a regeneration zone. During the rotation of the rotary disk, the rotary disk cyclically passes through a moisture adsorption zone and a regeneration zone to continuously adsorb moisture and desorb moisture. In this way, the dry circulating airflow can be continuously obtained and enter the drum to be in fully contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. The temperature regulator 12 is provided at the outer side of the heater housing 11, which can prevent the temperature regulator 12 from being damaged due to its position in a high-temperature and humid environment for a long time. In addition, a temperature detector may be provided in the accommodating space to detect the temperature of the regeneration airflow in the accommodating space. When the clothing treatment apparatus performs the dehydration or drying process, the power of the heater can be regulated up by the temperature regulator 12 if the detected temperature of the regeneration airflow is too low, so as to increase the operating temperature of the heater and increase the heating temperature of the regeneration airflow. The power of the heater can be regulated down by the temperature regulator 12 if the detected temperature of the regeneration airflow is too high, so as to reduce the operating temperature of the heater and reduce the heating temperature of the regeneration airflow. In this way, the moisture adsorption efficiency of the rotary disk can be improved, the drying time can be reduced, and energy can be saved.

[0056] The rotary disk 200 can be made of a material with good moisture adsorption performance, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The rotary disk member may include the rotary disk 200 and a driving assembly, the driving assembly may include a motor, and the motor may drive the rotary disk 200 to rotate. The wet circulating airflow discharged from the drum enters the bottom of the accommodating cavity of the rotary disk, and the wet circulating airflow in the moisture adsorption zone 1-1 passes through the rotary disk 200 from bottom to top. The rotary disk 200 adsorbs the moisture in the wet circulating airflow, such that the wet circulating airflow can be turned into a dry circulating airflow. The dry circulating airflow enters the drum through an intake port of the drum and is in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. In this process, the wet circulating airflow may bring some fine fluff into the rotary disk 200, and the fine fluff may adhere to the rotary disk 200 when passing through the rotary disk. The regeneration member may include a heater for heating the regeneration airflow, and the temperature of the heated regeneration airflow may reach 140° C.-200° C., such that during the regeneration process of the rotary disk 200, the fine fluff is easy to turn into burnt matter at such a high temperature. Bacteria and viruses are likely to proliferate on the burnt matter if the burnt matter remains in such a high-temperature and humid environment for a long time, and the bacteria and viruses may enter the drum along with the circulating airflow to pollute the clothing.

[0057] To solve this problem, an embodiment of the present application provides a drying module. As shown in FIGS. 3-7, the drying module includes: a rotary disk, a rotary disk housing, and a heating device including a first heater 320 and a second heater 330. The rotary disk housing is configured to accommodate the rotary disk. The rotary disk housing is divided into at least a moisture adsorption zone 1-1, a regeneration zone 1-2, and a deodorization zone 1-3 in a rotation direction of the rotary disk, and the deodorization zone 1-3 is located downstream of the regeneration zone 1-2. The first heater 320 is provided corresponding to the regeneration zone 1-2 and configured to desorb moisture adsorbed on at least a part of the rotary disk rotating through the regeneration zone. The second heater 330 is provided corresponding to the deodorization zone 1-3. The first heater 320 may be configured to heat the regeneration airflow to desorb the moisture adsorbed by the rotary disk. The second heater 330 may be configured to heat the deodorizing airflow to partially remove the burnt matter generated on the rotary disk during regeneration. The first heater 320 and the second heater 330 are arranged adjacent to the rotary disk 200, and the second heater 330 is arranged downstream of the first heater 320 relative to the rotation direction of the rotary disk 200. The first heater 320 and the second heater 330 may be, for example, independent units. The first heater 320 and the second heater 330 each include an independent heating tube, and the change of the heating temperature is controlled by controlling the power of the heating tube. The first heater 320 and the second heater 330 may be arranged above the rotary disk 200, preferably at a height not in contact with the rotary disk 200. During the rotation of the rotary disk 200, the rotary disk may first pass through the regeneration zone 1-2 corresponding to the first heater 320, and then pass through the deodorization zone 1-3 corresponding to the second heater 330. After the regeneration airflow passes through the first heater 320, the temperature of the heated regeneration airflow may reach 140° C.-200° C. After the deodorizing airflow passes through the second heater 330, the temperature of the heated deodorizing airflow may reach above 250° C. The heated regeneration airflow passes through the rotary disk 200 from top to bottom to dehydrate and dry a part of the rotary disk 200 in the regeneration zone. The heated deodorizing airflow passes through the rotary disk 200 from top to bottom to remove the burnt matter from a part of the rotary disk 200 in the deodorization zone. The burnt matter can be carbonized at the high temperature, such that the burnt matter can be prevented from mold growth and the proliferation of bacteria and viruses caused by long-term presence of the burnt matter in a high-temperature and humid environment, thereby achieving sterilization and deodorization. As shown in FIG. 9, the rotary disk housing can be divided into three operating zones, i.e., the moisture adsorption zone 1-1, the regeneration zone 1-2, and the deodorization zone 1-3. In the moisture adsorption zone 1-1, the wet circulating airflow from the drum passes through the rotary disk 200 from bottom to top, and the rotary disk 200 adsorbs the moisture in the wet circulating airflow, such that the wet circulating airflow can be turned into a dry circulating airflow. The arrow direction in FIG. 9 is the rotation direction of the rotary disk 200. Therefore, during the rotation of the rotary disk 200, the rotary disk cyclically passes through the moisture adsorption zone 1-1, the regeneration zone 1-2, and the deodorization zone 1-3 in turn, to continuously adsorb moisture, desorb moisture, and sterilize and deodorize. In this way, a dry and clean circulating airflow can be continuously obtained and enter the drum to be in full contact with the clothing in the drum, thereby improving the drying efficiency and reducing the energy consumption.

[0058] In some embodiments, the rotary disk housing is provided with a heater mounting part, the heater mounting part is in communication with the rotary disk, and the heater mounting part includes at least a first heater accommodating region and a second heater accommodating region. The first heater is mounted in the first heater accommodating region to form the regeneration zone, and the second heater is mounted in the second heater accommodating region to form the deodorization zone. The first heater 320 is located in the regeneration zone; the second heater 330 is located in the deodorization zone; and the deodorization zone is located downstream of the regeneration zone relative to the rotation direction of the rotary disk.

[0059] In some embodiments, the drying module further includes a heater housing, and the first heater and the second heater are both accommodated in the heater housing. Specifically, the heater housing may include: a top wall 112 and a side wall 113 protruding from a periphery of the top wall 112 to form the accommodating cavity, and a base 111 protruding outward along the side wall 113. The base 111 may be provided with a mounting hole, and the base may be connected and fixed to the upper rotary disk housing 210 through the mounting hole. The first heater 320 and the second heater 330 may each include an independent heating tube, and the heating tube is distributed in an S-shape, such that the length of the heating tube distributed in the regeneration zone and the length of the heating tube distributed in the deodorization zone can be larger, so as to increase the contact area with the regeneration airflow and the deodorizing airflow, thereby achieving a higher heat exchange efficiency with the regeneration airflow and the deodorizing airflow. The change of the heating temperature is controlled by controlling the power of the heating tube. The heating tube heats the surface of the rotary disk 200. During the rotation of the rotary disk 200, the rotary disk may first pass through the first heater 320 and then pass through the second heater 330. By arranging the regeneration airflow and the deodorizing airflow with different temperatures after heating and passing through the rotary disk 200 from top to bottom separately, the rotary disk 200 can be heated more uniformly, thereby implementing the process of desorbing moisture from, and sterilization and deodorization of, a part of the rotary disk 200.

[0060] In some embodiments, the first heater is operated at a first temperature, the second heater is operated at a second temperature, and the second temperature is higher than the first temperature. The first temperature may be, for example, 140° C.-200° C., so as to heat the regeneration airflow. The heated regeneration airflow passes through the rotary disk 200 from top to bottom, so as to dehydrate and dry a part of the rotary disk 200 in the regeneration zone. The second temperature may be, for example, above 250° C., so as to heat the deodorizing airflow. The heated deodorizing airflow passes through the rotary disk 200 from top to bottom, so as to remove the burnt matter from a part of the rotary disk 200 in the deodorization zone, and the burnt matter may be carbonized at the high temperature.

[0061] In some embodiments, the temperature of the heated deodorizing airflow is higher than that of the heated regeneration airflow. The regeneration airflow passes through the first heater 320, and the temperature of the heated regeneration airflow may be set to be 140° C.-200° C. The deodorizing airflow passes through the second heater 330, and the temperature of the heated deodorizing airflow may be set to be above 250° C. Through testing, 4 samples were obtained by sampling a polluted and discolored rotary disk 200, which were respectively subjected to roasting experiments at 150° C., 200° C., 300° C., and 400° C. for observation. It was found that at 250° C., the carbon deposit on the sample began to become shallow, and at 400° C., the carbon deposit on the sample was completely removed. Therefore, the temperature of the heated deodorizing airflow can be set to be above 250° C., so as to realize sterilization and deodorization of a part of the rotary disk 200.

[0062] In some embodiments, a first partition member 340 is provided in the heater housing substantially in the radial direction to separate an inner space of the heater housing, such that the first heater 320 and the second heater 330 are separately arranged at two sides of the first partition member 340. The heater housing is of a sector-shaped structure. The first partition member 340 is arranged in the accommodating cavity, and the first partition member 340 extends along the radial direction of the sector-shaped structure, such that the accommodating cavity is divided into the regeneration zone and the deodorization zone. The first partition member 340 may be made of a heat insulation material, such that the heating temperatures of the regeneration zone and the deodorization zone can be accurately controlled. One end of the first partition member 340 is connected to the outer arc side wall of the heater housing, and the other end extends towards the center of a circle of the sector-shaped structure and is connected to the side wall of the heater housing, thereby dividing the accommodating cavity into the regeneration zone and the deodorization zone. In other embodiments, the first partition member 340 may not be provided in the accommodating cavity. Since the heating tubes heat the surface of the rotary disk 200, the heating temperature can be roughly controlled by actively controlling the power of the two heating tubes, and the heat is freely transferred between the two zones, which can achieve a certain degree of energy saving.

[0063] In some embodiments, an area of the first heater accommodating region is greater than or equal to that of the second heater accommodating region. That is, the area of the regeneration zone may be set to be greater than or equal to the area of the deodorization zone. In order to restore the moisture adsorption capacity of a part of the rotary disk 200 after having the moisture desorbed, the area of the regeneration zone may be set to be greater than the area of the deodorization zone, thereby further improving the drying efficiency and drying effect of the rotary disk 200 desorbing moisture.

[0064] In some embodiments, air inlets are provided on the outer arc side wall or the substantially radial side wall of the heater housing, and the air inlets include a first air inlet and a second air inlet, where the first air inlet is configured to introduce air into the space of the first heater, and the second air inlet is configured to introduce air into the space of the second heater. In an exemplary embodiment, the air inlets 16 are provided on the outer arc side wall of the heater housing; and the air inlets 16 are in communication with the accommodating cavity. In the embodiments of the present application, it is a preferred solution that the heater housing is of a sector-shaped structure.

[0065] The heater housing may also be of an irregular structure, which is not limited herein. The heater housing is cooperatively connected to the upper rotary disk housing 210, such that the moisture adsorption zone is separated from the regeneration zone and the deodorization zone, i.e., the wet circulating airflow in the moisture adsorption zone can be largely isolated from the regeneration airflow and the deodorizing airflow. Specifically, the same airflow with the same flow rate and direction enters the accommodating cavity through the air inlet, and may be heated by the first heater 320 to obtain the regeneration airflow, and heated by the second heater 330 to obtain the deodorizing airflow.

[0066] In an exemplary embodiment, the air inlets 16 include a first air inlet and a second air inlet, and the first air inlet and the second air inlet may be separately arranged at two ends close to the outer arc side wall of the housing. The first air inlet is in communication with the regeneration zone, such that the moisture adsorbed on the rotary disk is desorbed by the heated regeneration airflow. The second air inlet is in communication with the deodorization zone, such that the burnt matter generated on the rotary disk during the regeneration process is removed by the heated deodorizing airflow. Specifically, the first air inlet and the second air inlet are provided on the outer arc side wall 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 separate the accommodating cavity into the regeneration zone and the deodorization zone. Two separate airflows are separately introduced through the first air inlet and the second air inlet, and at this time, the flow rates of the two airflows can be controlled separately. For example, the flow rate of the airflow introduced into the regeneration zone is larger, and the flow rate of the airflow introduced into the deodorization zone is smaller. In order to facilitate the regulation and control of the flow rates of the two airflows, the two airflows may be two airflows separated from the outlet of a single fan, or may be airflows provided by two separate fans, which is not further limited in the embodiments of the present application.

[0067] In some embodiments, the heater housing includes: a first heater housing and a second heater housing. The first heater 320 is accommodated in the first heater housing, and the second heater 330 is accommodated in the second heater housing. In this way, the first heater 320 and the second heater 330 are configured as two independent units, and the heating temperatures of the first heater 320 and the second heater 330 are accurately controlled.

[0068] In some embodiments, the first air inlet and the second air inlet are respectively provided on the outer arc side wall or the substantially radial side wall of each of the first heater housing and the second heater housing, and configured to respectively introduce air into the space of the first heater and the space of the second heater. The first air inlet is provided on the outer arc side wall or the substantially radial side wall of the first heater housing, and the second air inlet is provided on the outer arc side wall or the substantially radial side wall of the second heater housing, so as to accurately control the regeneration airflow and the deodorizing airflow, separately.

[0069] In an exemplary embodiment, an air intake volume of the first air inlet is greater than or equal to that of the second air inlet. In this way, the flow rate of the regeneration airflow can be controlled to be greater than that of the deodorizing airflow. In order to restore the moisture adsorption capacity of a part of the rotary disk 200 after having the moisture desorbed, the flow rate of the regeneration airflow may be set to be greater than that of the deodorizing airflow, thereby further improving the drying efficiency and drying effect of the rotary disk 200 desorbing moisture, and avoiding an excessively high temperature of the discharged airflow due to an excessively high flow rate of the deodorizing airflow.

[0070] In some embodiments, the drying module further includes: an air homogenizing member, which may be located above or below the first heater 320 and the second heater 330, i.e., the air homogenizing member is adjacent to or spaced apart from the rotary disk. The regeneration airflow enters the regeneration zone, and passes through the air homogenizing member / the first heater 320, the first heater 320 / the air homogenizing member, and the rotary disk in sequence. The deodorizing airflow enters the deodorization zone, and passes through the air homogenizing member / the second heater 330, the second heater 330 / the air homogenizing member, and the rotary disk in sequence. The air homogenizing member may be an air conditioning plate, the air homogenizing member is sector-shaped, and the air homogenizing member is provided with air holes 14 that are spaced apart from each other. The air homogenizing member may be arranged upstream or downstream of the first heater 320 and the second heater 330. Of course, upstream is a preferred choice. The air homogenizing member guides the airflow flowing into the heater accommodating space through the air holes 14 such that the regeneration airflow and the deodorizing airflow can fully transfer the heat of the heater to the rotary disk 200. In this case, the heater is closer to the rotary disk, and the air homogenizing member is spaced apart from the rotary disk. The air homogenizing member may also be arranged downstream of the first heater 320 and the second heater 330. In this case, the advantage is that the regeneration airflow is in full contact with the heater first, such that the regeneration airflow and the deodorizing airflow are uniformly heated, and then the hot airflow flows to the rotary disk 200 through the guidance of the air homogenizing member. In this case, the air homogenizing member is arranged adjacent to the rotary disk, and the heater is spaced apart from the rotary disk. In addition to homogenizing the airflow and guidance, the air homogenizing member can protect the heating tube of the heater to a certain extent. Alternatively, the air homogenizing member can be omitted, and the regeneration airflow and the deodorizing airflow flow directly to the rotary disk after flowing through the heater, thereby saving costs and reducing the complexity of the mechanism.

[0071] In some embodiments, a drying module, as shown in FIG. 8, may specifically include: a circulation module 10, a dehumidification module 20, and a heating device 30. The circulation module 10 is provided with a first circulation path that is in communication with an outlet port of the drum to allow the wet circulating airflow in the drum to enter the first circulation path. The dehumidification module is provided with a second circulation path, where the dehumidification module 20 is located downstream or upstream of the circulation module 10. The outlet port of the drum, the first circulation path, the second circulation path, and the intake port of the drum are communicated in sequence to form a circulation path. The dehumidification module 20 includes a moisture adsorption-desorption member, at least a part of the moisture adsorption-desorption member is arranged on the second circulation path, and the moisture adsorption-desorption member is configured to adsorb moisture in the wet circulating airflow from the drum. The heating device 30 includes: a first heater 320 configured to heat the regeneration airflow to partially desorb the moisture adsorbed by the rotary disk; and a second heater 330 configured to heat the deodorizing airflow to partially remove the burnt matter generated on the rotary disk during the regeneration process. The circulation module 10 may include a circulation fan, the arrangement of the circulation fan may provide power for the wet circulating airflow to facilitate the circulation of the airflow, an air inlet of the circulation fan is in communication with the outlet port of the drum, and an air outlet of the circulation fan is in communication with the second circulation path. The moisture adsorption-desorption member is arranged on the second circulation path, and the moisture adsorption-desorption member may first adsorb moisture in the wet circulating airflow from the drum, such that the wet circulating airflow is turned into a relatively dry circulating airflow, and the dry circulating airflow enters the drum through the intake port of the drum and is in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. In order to enable the moisture adsorption-desorption member to be used continuously and repeatedly, the regeneration airflow passes through the first heater 320, and the temperature of the heated regeneration airflow can reach 140° C.-200° C. The deodorizing airflow passes through the second heater 330, and the temperature of the heated deodorizing airflow can reach above 250° C. The heated regeneration airflow passes through the rotary disk 200 from top to bottom to dehydrate and dry a part of the rotary disk 200 in the regeneration zone. The heated deodorizing airflow passes through the rotary disk 200 from top to bottom to remove the burnt matter from a part of the rotary disk 200 in the deodorization zone. Therefore, during the rotation of the rotary disk 200, the rotary disk cyclically passes through the moisture adsorption zone, the regeneration zone, and the deodorization zone in turn, to continuously adsorb moisture, desorb moisture, and sterilize and deodorize. In this way, a dry and clean circulating airflow can be continuously obtained and enter the drum to be in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. The moisture adsorption-desorption member may be, for example, the rotary disk 200.

[0072] In some embodiments, the rotary disk housing may include: an upper rotary disk housing 210 and a lower rotary disk housing 220. A substantially sector-shaped heater mounting part is formed on the upper rotary disk housing 210, and the heating device may be located above the rotary disk 200 by being arranged in the heater mounting part. In an exemplary embodiment, the lower rotary disk housing 220 may be provided with a first rotary disk accommodating region, the lower rotary disk housing 220 may include a bottom plate and a circumferential side wall protruding from the bottom plate, and the formed recessed part is the first rotary disk accommodating region. Similarly, the upper rotary disk housing 210 may be provided with a second rotary disk accommodating region, the second rotary disk accommodating region includes at least the moisture adsorption zone, but does not include the regeneration zone or the deodorization zone, and a heater mounting part is provided at the radial edge of the second rotary disk accommodating region. The second rotary disk accommodating region and a part of the first rotary disk accommodating region together form at least the moisture adsorption zone, and the heater mounting part and the other part of the first rotary disk accommodating region together form the regeneration zone and the deodorization zone. Since the airflow passes through the accommodating cavity of the rotary disk, the upper rotary disk housing 210 and the lower rotary disk housing 220 may be connected in a sealed manner. For example, the upper rotary disk housing 210 or the lower rotary disk housing 220 is respectively provided with a groove or a flange, and a sealing strip is provided in the groove. When the upper rotary disk housing 210 and the lower rotary disk housing 220 are in snap-fit connection, the flange abuts against the sealing strip in the groove to achieve sealing.

[0073] As shown in FIG. 5, in some embodiments, a first airflow path is provided in the heating device 30, and the drying module further includes a fan 301. The fan 301 is arranged on the first airflow path, and the fan 301 is located upstream of the heating device 30. The first airflow is divided into two airflows through the first air inlet and the second air inlet, and the two airflows enter the regeneration zone and the deodorization zone, to form the regeneration airflow and the deodorizing airflow, separately. The arrangement of the fan 301 may provide power for the first airflow, thereby facilitating circulation of the first airflow and improving the efficiency.

[0074] In some embodiments, the drying module further includes a condensation module 40. The condensation module 40 may specifically include a first condensation device 7. The first condensation device 7 is arranged on the first airflow path, the first condensation device is located downstream of the rotary disk 200, and the first condensation device is located upstream of the fan 301, such that the hot and wet regeneration airflow and deodorizing airflow in the first airflow path enter the first condensation device 7 and are turned into a dry and cold first airflow to enter the fan 301, and that a closed loop is formed for the first airflow to circulate. When the rotary disk 200 rotates to the first airflow path, the first airflow can be divided into two airflows, i.e., the regeneration airflow and the deodorizing airflow can be formed. As shown in FIG. 7, the regeneration airflow passes through the rotary disk 200 from top to bottom and heats that part of the rotary disk 200, such that the moisture in that part is quickly evaporated and taken away by the regeneration airflow. In addition, the deodorizing airflow passes through the rotary disk 200 from top to bottom and heats that part of the rotary disk 200, such that the carbon deposit on that part of the rotary disk 200 is removed, thereby achieving the effects of sterilization and deodorization. At this time, the regeneration airflow and the deodorizing airflow are combined into the hot and wet first airflow that enters the first condensation device 7. Therefore, the rotary disk 200 always has a good moisture adsorption capacity, and the efficiency and effect of moisture adsorption of the rotary disk 200 are further improved. The arrow direction in FIG. 7 indicates the flow direction of the first airflow. In an exemplary embodiment, the hot and wet first airflow enters the first condensation device 7 for heat exchange and cooling, the water vapor in the first airflow is cooled to form condensed water, which is discharged from the first condensation device 7, and the dry low-temperature first airflow enters the fan 301 for a next cycle. In an optional embodiment, the hot and wet first airflow enters the first condensation device 7 for heat exchange and cooling, the water vapor in the first airflow is cooled to form condensed water, which is discharged from the first condensation device 7, and the dry low-temperature first airflow can be discharged to the atmosphere through the air outlet of the first condensation device 7, so as to avoid adverse effects on the atmospheric temperature and humidity of the space where the clothing treatment apparatus is located. Therefore, the first airflow can form an open cycle.

[0075] As shown in FIGS. 10-13, the drying module includes: a rotary disk housing 411, a rotary disk 200, and a sealing structure. The rotary disk housing 411 is provided with a recessed accommodating space, where a second partition member 412 is provided in the rotary disk housing 411 to separate the accommodating space into a first circulating air duct and a second circulating air duct. The rotary disk 200 is mounted on the rotary disk housing 411 to cover the first circulating air duct and the second circulating air duct, where the rotary disk 200 is rotatably connected to the rotary disk housing 411. The sealing structure is located between the rotary disk 200 and the rotary disk housing 411, where the sealing structure is mounted on the second partition member 412, and the sealing structure is adjacent to or in contact with the rotary disk 200 to prevent airflow communication between the first circulating air duct and the second circulating air duct. The rotary disk housing 411 may be provided with a bottom wall and a circumferential side wall protruding from the bottom wall to enclose the recessed accommodating space. A gap is formed between one side surface of the rotary disk 200 and the bottom wall. The accommodating space is separated into the first circulating air duct and the second circulating air duct by the protruding second partition member 412 provided on the bottom wall. The first circulating air duct may be in communication with the outlet port of the drum, for example, such that the wet circulating airflow discharged from the drum enters the first circulating air duct. A dry regeneration airflow may be introduced into the second circulating air duct, for example. Therefore, the wet circulating airflow discharged from the drum enters and disperses in the first circulating air duct. The wet circulating airflow may pass through the rotary disk 200, and the rotary disk adsorbs moisture in the wet circulating airflow, such that the wet circulating airflow may be turned into a dry circulating airflow, and the dry circulating airflow enters the drum through the intake port of the drum and is in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. Meanwhile, the dry regeneration airflow enters and disperses in the second circulating air duct. The dry regeneration airflow may pass through the rotary disk 200 to desorb moisture from that part of the rotary disk. The rotary disk 200 rotates relative to the rotary disk housing 411, and the rotary disk 200 cyclically passes through the first circulating air duct and the second circulating air duct in the circumferential rotation process to continuously adsorb moisture and desorb moisture, such that the rotary disk 200 always has a good moisture adsorption capacity, thereby improving the efficiency and effect of moisture adsorption. By mounting the sealing structure on the second partition member 412, the rotary disk 200 does not interfere with the sealing structure facing the side surface thereof during rotation, while they are close enough, such that the two airflows in the first circulating air duct and the second circulating air duct can be isolated to achieve a dynamic sealing effect, thereby improving the drying efficiency of the drying module and reducing the energy consumption.

[0076] In some embodiments, the rotary disk housing 411 may include a first housing (or referred to as an upper rotary disk housing) and a second housing (or referred to as a lower rotary disk housing). The rotary disk 200 is located between the first housing and the second housing. For example, the second partition member 412 is arranged on the first housing to form the first circulating air duct and the second circulating air duct. In the same way, the second partition member 412 may also be correspondingly arranged on the second housing to form the first circulating air duct and the second circulating air duct. In order to prevent the wet circulating airflow discharged from the drum and the regeneration airflow from crossing each other, the sealing structure may be arranged on each of the second partition members 412, to achieve a dynamic sealing effect with the rotary disk 200, thereby facilitating continuous adsorption of moisture and dehydration and drying of the rotary disk 200 through the first circulating air duct and the second circulating air duct during the rotation of the rotary disk, such that the rotary disk 200 always has a good moisture adsorption capacity, thereby improving the efficiency and effect of moisture adsorption. Moreover, in order to achieve the balance of the rotary disk 200, the flow directions of the wet circulating airflow and the regeneration airflow may be set to be opposed or opposite. For example, in the first circulating air duct, the wet circulating airflow may pass through the rotary disk 200 from bottom to top; and in the second circulating air duct, the regeneration airflow may pass through the rotary disk 200 from top to bottom.

[0077] In some embodiments, the sealing structure includes a flexible member that is adjacent to or in contact with the rotary disk 200. The flexible member may be made of soft rubber or bristles, which exhibit a certain amount of elastic deformation. When in proximity to or contact with the surface of the rotary disk 200, the soft rubber or bristles do not interfere with rotation of the rotary disk 200, such that the two airflows in the first circulating air duct and the second circulating air duct can be isolated to achieve a dynamic sealing effect. Foamed EPDM is generally used as the sealing strip for a drying unit in a conventional condensing-type integrated washer-dryer machine, but the foamed EPDM is only suitable for sealing between two relatively static parts. If the foamed EPDM is used between two relatively moving parts, the foamed EPDM will be worn quickly, which is not conducive to sealing.

[0078] In view of this, in some embodiments, the flexible member is configured as a brush 414. The brush 414 includes a brush base and a number of soft bristles densely arranged on the brush base. Since soft bristles are densely distributed on the brush 414, the soft bristles may be in contact with the surface of the rotary disk 200, to achieve sealing with the rotary disk 200. Meanwhile, the brush 414 exhibits wear resistance, such that the rotary disk 200 will not wear the brush 414 even if it rotates for a long time, which facilitates isolation and prevents crossing of the two airflows in the first circulating air duct and the second circulating air duct, thereby further ensuring the reliability of the apparatus for long-term use.

[0079] In some embodiments, the sealing structure further includes a holder 415. One side of the holder 415 is in snap-fit connection or screw connection to the brush base, and the other side of the holder 415 is connected and fixed to the second partition member 412. Specifically, a bump may be provided on the brush base, and a matching groove may be correspondingly provided on the holder 415. The bump is inserted into the groove to form an interference fit, such that the position of the brush base and the position of the holder 415 are relatively fixed. Alternatively, the position of the brush base and the position of the holder 415 may be relatively fixed through a screw connection. For example, on the brush base, a nut of a screw may be sunk into the brush base such that the nut can be prevented from protruding and interfering with the rotation of the rotary disk 200. A protruding mounting post may be provided on the other side of the holder 415, and the mounting post may be inserted into the second partition member 412 and locked and fixed by a threaded fastener from the outer side of the rotary disk housing 411, where the threaded fastener may be a self-tapping screw. In this way, the mounting is convenient and the structure is compact. In addition, the sealing structure is not affected by a high-speed airflow and is not displaced due to long-term use, thereby further ensuring the reliability of use.

[0080] In some embodiments, the second partition member 412 is arranged along the radial direction of the rotary disk housing 411, such that the first circulating air duct and the second circulating air duct are both substantially sector-shaped spaces. In this way, during the rotation of the rotary disk 200, the rotary disk may cyclically pass through the first circulating air duct and the second circulating air duct to continuously adsorb moisture and desorb moisture, such that the rotary disk 200 always has a good moisture adsorption capacity.

[0081] In some embodiments, the second partition member 412 includes at least a first partition member body and a second partition member body, the first partition member body and the second partition member body are both arranged along the radial direction of the rotary disk housing 411, one end of each of the first partition member body and the second partition member body is connected to an inner side wall of the rotary disk housing 411, and the other end of each of the first partition member body and the second partition member body intersects at a central region of the rotary disk housing 411, such that the second partition member 412 is substantially V-shaped. The intersection of the first partition member body and the second partition member body is connected through a circular arc transition. Both the first partition member body and the second partition member body may be provided with sealing structures, and each sealing structure is arranged along the radial direction of the rotary disk housing 411. During the rotation of the rotary disk 200, the brush 414 is always in contact with the surface of the rotary disk 200, thereby achieving isolation and preventing crossing of the two airflows in the first circulating air duct and the second circulating air duct.

[0082] In some embodiments, an included angle between the first partition member body and the second partition member body is set to be 60-70 degrees. Preferably, the included angle between the first partition member body and the second partition member body is set to be 65 degrees. The V-shaped region formed by the included angle between the first partition member body and the second partition member body may be configured as the second circulating air duct, and the remaining region may be configured as the first circulating air duct. An area of the first circulating air duct may be set to be greater than that of the second circulating air duct, such that a majority of the rotary disk 200 is in a region for adsorbing the moisture in the wet circulating airflow, thereby further improving the moisture adsorption efficiency and the moisture adsorption effect of the rotary disk 200. In order to prevent the wet circulating airflow discharged from the drum and the regeneration airflow from crossing each other, a certain dynamic sealing effect may be formed between the sealing structure and the rotary disk 200. When the rotary disk 200 rotates to the second circulating air duct, the regeneration airflow heats that part of the rotary disk 200, such that the moisture in that part is quickly evaporated and taken away by the regeneration airflow, such that the rotary disk 200 always has a good moisture adsorption capacity, thereby improving the efficiency and effect of moisture adsorption.

[0083] In some embodiments, a protruding mounting shaft 416 is provided at the intersection of the first partition member body and the second partition member body, and the rotary disk 200 is rotatably connected to the mounting shaft 416. The mounting shaft 416 may be configured as a fixed shaft or a rotation shaft. When the mounting shaft 416 is the fixed shaft, a driving assembly may be arranged in a circumferential direction of the rotary disk 200, the driving assembly may include a motor, and the motor drives the rotary disk 200 to rotate. When the mounting shaft 416 is the rotation shaft, the motor drives the rotation shaft to rotate to drive the rotary disk 200 to rotate.

[0084] In some embodiments, the rotary disk 200 is of an air-permeable and porous structure. The rotary disk 200 can be made of a material with good moisture adsorption and desorption performance, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve.

[0085] In order to realize the drying function of clothes and the like, the technical solution adopted by a clothing treatment apparatus, such as a dryer, an integrated washer-dryer machine, and a clothes care machine, may be to remove the moisture in the air by a drying module. The dehumidification principle of the drying module is mainly to adsorb the moisture in the air through an adsorption medium in a moisture adsorption-desorption member, the adsorption medium adsorbs the moisture in the air through condensation, and the moisture absorbed by the moisture adsorption-desorption member is released by heating the adsorption medium, thereby achieving cyclic utilization of the moisture adsorption-desorption member.

[0086] Therefore, in general, the moisture adsorption-desorption member has the adsorption medium to form a rotary disk. The dehumidifying rotating wheel is typically divided into two zones, as shown in FIG. 14, including a moisture adsorption zone 1-1 and a regeneration zone 1-2, and a mounting shaft 416, with the arrow in the figure being used for indicating the rotation direction of the rotary disk.

[0087] The adsorption medium in the moisture adsorption zone 1-1 of the rotary disk adsorbs moisture in the air. Meanwhile, a power component, such as a drive motor or a gear (not shown in FIG. 14) drives the mounting shaft 416 to rotate, such that the dehumidifying rotating wheel rotates. The adsorption medium in the moisture adsorption zone 1-1 of the rotary disk absorbs moisture in the air, such that the air becomes dry, thereby providing dry air. Driven by the power component, the rotary disk rotates to transfer the adsorption medium with the adsorbed moisture from the moisture adsorption zone to the regeneration zone 1-2. The temperature of the regeneration zone 1-2 is higher than that of the moisture adsorption zone 1-1, and the moisture adsorption-desorption member has the moisture in the adsorption medium in the regeneration zone 1-2 evaporated and removed by raising the temperature, such as using a heater to allow a fan to blow out a hot airflow, or using a heating fan or another technical solution to evaporate and remove the moisture absorbed by the adsorption medium in the rotary disk. The moisture adsorption-desorption member then has the moisture released from the regeneration zone 1-2 taken away, such as using a fan to remove the moisture through an air outlet pipe, and other ways to take away the moisture released from the regeneration zone 1-2. Driven by the power component, the rotary disk continues to rotate, and the adsorption medium in the regeneration zone 1-2 enters the moisture adsorption zone 1-1 again for adsorption and dehumidification, thereby achieving regeneration and restoration of the adsorption medium of the rotary disk.

[0088] The problem with such a technical solution is that when the adsorption medium in the regeneration zone 1-2 just enters the moisture adsorption zone 1-1, such as the region from the dashed line to the edge of the regeneration zone 1-2 as shown in FIG. 14, some heat remains on the adsorption medium, which will affect the dehumidification effect in the moisture adsorption zone 1-1. Therefore, the existing technical solution cannot achieve high dehumidification efficiency of the drying module, resulting in low dehumidification efficiency of the clothing treatment apparatus.

[0089] In order to solve the above technical problem, an embodiment of the present application provides a drying module. The drying module includes a clothing treatment container, a moisture adsorption-desorption member, and a first fan. The clothing treatment container is configured to remove moisture from clothing to form a wet airflow. The first fan is configured to introduce the wet airflow into the moisture adsorption-desorption member and introduce a dry airflow dehumidified by the moisture adsorption-desorption member into the clothing treatment container. The moisture adsorption-desorption member includes a moisture adsorption zone, a regeneration zone, and a cooling zone in sequence, where the moisture adsorption zone is in communication with the clothing treatment container, and the moisture adsorption zone is configured to adsorb the moisture in the wet airflow; the regeneration zone is configured to be heated to have the moisture adsorbed by the moisture adsorption-desorption member removed to restore the moisture adsorption capacity of the moisture adsorption-desorption member; and the cooling zone is located upstream of the moisture adsorption zone and configured to reduce the temperature of the moisture adsorption-desorption member to improve the dehumidification capacity of the moisture adsorption-desorption member, where the moisture adsorption zone, the regeneration zone, and the cooling zone are independent of each other. The following provides descriptions with reference to specific embodiments.

[0090] FIG. 15 shows a schematic diagram of an appearance structure of a clothing treatment apparatus, FIG. 16 shows a schematic diagram of a lower housing of a drying module of a clothing treatment apparatus, and FIG. 17 is a schematic diagram illustrating a region division of a rotary disk in a moisture adsorption-desorption member.

[0091] A drying module includes a clothing treatment container 1, a first fan 2, and a moisture adsorption-desorption member 3. As shown in FIG. 15, the clothing treatment container 1 is configured to remove moisture from clothing to form a wet airflow. If the clothing treatment apparatus is an integrated washer-dryer machine, the clothing treatment container 1 may be a clothes-washing drum, and if the clothing treatment apparatus is a dryer, the clothing treatment container 1 may be a drying chamber. Those skilled in the art can determine the specific clothing treatment container 1 according to different clothing treatment apparatuses based on the concept of the present application.

[0092] As shown in FIG. 21, the first fan 2 is configured to introduce the wet airflow into the moisture adsorption-desorption member 3 and introduce a dry airflow dehumidified by the moisture adsorption-desorption member 3 into the clothing treatment container 1. There may be one or more first fans 2, which is not limited herein, and may be reasonably set according to actual needs. If the clothing treatment apparatus is an integrated washer-dryer machine or the like, the first fan 2 may be of an existing fan structure. Without being limited by costs, the first fan may also be a refrigeration fan or other fans, as long as the airflow to be dehumidified in the clothing treatment container 1 can be introduced into the moisture adsorption-desorption member 3 and the dry airflow dehumidified by the moisture adsorption-desorption member 3 can be introduced into the clothing treatment container 1. The moisture adsorption-desorption member 3 may include a moisture adsorption zone 1-1, a regeneration zone 1-2, and a cooling zone 33 in sequence along the rotation direction thereof. The moisture adsorption zone 1-1 is in communication with the clothing treatment container 1, and the moisture adsorption zone 1-1 is configured to adsorb moisture in the wet airflow. The communication between the moisture adsorption zone 1-1 and the clothing treatment container 1 may be implemented in the form of an air path channel. Those skilled in the art can understand that the communication between the moisture adsorption zone 1-1 and the clothing treatment container 1 refers to flow and circulation of the air in the moisture adsorption zone 1-1 and the air in the clothing treatment container 1. Under the action of the first fan 2, the air in the moisture adsorption zone 1-1 and the air in the clothing treatment container 1 can flow and circulate quickly.

[0093] The communication in the embodiments of the present application refers to communication between spaces. When two spaces are communicated with each other, the air in the two spaces can freely interact, which can also be understood as having a communicating air path, which will not be repeated hereinafter.

[0094] The regeneration zone 1-2 is configured to be heated to have the moisture adsorbed by the moisture adsorption-desorption member 3 removed to restore the moisture adsorption capacity of the moisture adsorption zone 1-1. The cooling zone 33 is arranged adjacent to the regeneration zone 1-2 and may be located upstream of the moisture adsorption zone 1-1 along the rotation direction of the moisture adsorption-desorption member 3, and is configured to reduce the temperature of the moisture adsorption-desorption member 3 to improve the dehumidification capacity of the moisture adsorption-desorption member 3. The method for reducing the temperature of the cooling zone 33 is not limited in the technical solution of this embodiment. The method may include: using a fan to generate an airflow in the cooling zone 33, and using the airflow to achieve heat exchange to take away the heat of the cooling zone 33, thereby achieving the purpose of reducing the temperature of the moisture adsorption-desorption member 3; adding a refrigeration unit, and using the low temperature generated by the refrigeration unit to achieve the purpose of reducing the temperature of the rotary disk; and delivering a low-temperature airflow to the cooling zone 33 to achieve the purpose of reducing the temperature of the moisture adsorption-desorption member 3. Of course, the cooling zone 33 may also be cooled in other ways, which will not be listed herein, and those skilled in the art may make a reasonable design and layout according to the actual scenario based on the concept of the present application.

[0095] In an embodiment of the present application, the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 are independent of each other. The technical solution where the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 are independent of each other is not limited in the embodiment of the present application. Isolation plates and corresponding sealing members may be added between the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 to achieve the independence of each other. Alternatively, a corresponding isolation design may be achieved by integrally forming the moisture adsorption-desorption member and the housing. Alternatively, other technical solutions from those skilled in the art may be used to achieve the independence of each zone, as long as the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 are ensured to be independent of each other. Those skilled in the art may make reasonable settings according to the current scenario and actual needs. According to the technical solution in the embodiment of the present application, a separate cooling zone 33 is additionally added to the moisture adsorption-desorption member 3, and the temperature of the moisture adsorption-desorption member 3 is reduced in the cooling zone 33 to improve the dehumidification capacity of the moisture adsorption-desorption member 3. Under the action of the mounting shaft 416, after the adsorption medium in the cooling zone 33 rotates to the moisture adsorption zone 1-1, since the adsorption medium has been cooled in the cooling zone 33, the adsorption medium enters the moisture adsorption zone 1-1 in a cooled state, which can ensure the dehumidification effect of the adsorption medium in the moisture adsorption zone 1-1, improve the dehumidification efficiency of the drying module, and improve the dehumidification effect of the clothing treatment apparatus using this solution.

[0096] Further, in order to better illustrate the technical solutions of the present application, as shown in FIGS. 17 and 18, FIG. 17 further marks the moisture adsorption-desorption member 3 in detail, and FIG. 18 shows the corresponding relationship between the regions on the rotary disk 200 and the zones of the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 of the moisture adsorption-desorption member 3.

[0097] Specifically, the moisture adsorption-desorption member 3 includes a rotary disk 200, a rotary disk housing 411, and an isolation plate 4. The rotary disk housing 411, the rotary disk 200, and the isolation plate 4 are enclosed together to form the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 independent of each other. The moisture adsorption-desorption member 3 will be further described below. The rotary disk 200 is configured to adsorb the moisture in the wet airflow and be heated to have the adsorbed moisture removed. The region division of the rotary disk 200 corresponds to that of the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33. The rotary disk 200 is provided with an adsorption medium. The adsorption medium may be a moisture absorbent for absorbing the moisture, and may absorb moisture in the air and release the adsorbed moisture when heated.

[0098] The adsorption medium may be zeolite (molecular sieve), alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other media, which is not limited herein. For solid moisture absorbents such as zeolite (molecular sieve), alkali metal aluminosilicate (13X molecular sieve), lithium chloride, modified silica gel, and activated alumina, the moisture may be desorbed from the moisture absorbent by using a heating assembly. The heating assembly may include, for example, an element with a heating function, such as an electric heating wire and a heater, which is not limited herein.

[0099] The rotary disk housing 411 surrounds the rotary disk 200. The isolation plate 4 is located in the rotary disk housing 411. The rotary disk housing 411, the rotary disk 200, and the isolation plate 4 are enclosed together to form a dehumidification zone 1-1, the regeneration zone 1-2, and the cooling zone 33 independent of each other. The rotary disk 200 is provided with the adsorption medium as described above. The adsorption medium adsorbs moisture in the air. Meanwhile, a power component, such as a drive motor or a gear drives the rotary disk 200 to rotate, such that the rotary disk 200 rotates. The adsorption medium in the corresponding moisture adsorption zone 1-1 of the rotary disk 200 absorbs moisture in the air, such that the air becomes dry, thereby providing dry air. Driven by the power component, the rotary disk 200 rotates to transfer the adsorption medium with the adsorbed moisture from the moisture adsorption 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 adsorption zone 1-1. The moisture adsorption-desorption member 3 raises the temperature of the regeneration zone 1-2 in various ways, such as by heating, so as to remove the moisture from the adsorption medium in the regeneration zone 1-2. In an embodiment, a heater may be used to allow a fan to blow out a hot airflow, such that the temperature of the adsorption medium in the regeneration zone 1-2 can be increased when the hot airflow passes through the adsorption medium in the regeneration zone 1-2, that is, the moisture is released from the adsorption medium in the regeneration zone 1-2 in the rotary disk 200 by heating. The moisture adsorption-desorption member 3 then has the moisture released from the regeneration zone 1-2 taken away, such as using a fan to remove the moisture through an air outlet pipe, and other ways to take away the moisture released from the regeneration zone 1-2.

[0100] In an embodiment, the air path of the regeneration zone may be set as follows: the airflow passes through a regeneration fan, such that the moisture released from the regeneration zone 1-2 flows out through a ventilation pipeline, or the airflow passes through a condenser after passing through the regeneration fan, such that the airflow is subjected to condensation, and then the airflow enters the cooling zone 33, or merges with the circulating airflow, or is discharged to another place. Those skilled in the art may make reasonable settings according to actual needs. Driven by the power component, the rotary disk 200 continues to rotate, and the adsorption medium in the regeneration zone 1-2 enters the cooling zone 33. The moisture adsorption-desorption member 3 reduces the temperature of the adsorption medium in the cooling zone 33 in various ways to improve the dehumidification capacity of the moisture adsorption-desorption member. For example, when the airflow passes through the adsorption medium in the cooling zone 33, the heat of the adsorption medium in the cooling zone 33 is taken away by the flow of the air, such that the temperature of the adsorption medium in the cooling zone 33 is reduced, so as to improve the dehumidification capacity of the moisture adsorption-desorption member. Alternatively, a low-temperature airflow may be introduced into the cooling zone 33, and when the low-temperature airflow passes through the adsorption medium in the cooling zone 33, the temperature of the adsorption medium in the cooling zone 33 can be reduced. Alternatively, the temperature of the adsorption medium in the cooling zone 33 can also be reduced by adding a refrigeration device, etc., which may be set by those skilled in the art according to actual needs and is not limited herein.

[0101] The rotary disk housing 411 surrounds the rotary disk 200. As shown in FIG. 17, the rotary disk housing 411 is arranged around the outer side of the rotary disk 200. The isolation plate 4 is located in the rotary disk housing 411. The isolation plate 4 allows the spaces of the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33 to be independent of each other, such that the airs in the zones do not affect each other. For example, the moisture adsorption zone 1-1 and the cooling zone 33 will not have the airflows in their own regions affected due to a high-temperature airflow in the regeneration zone 1-2, and air mixing will not occur when the air path is arranged, which facilitates the arrangement of the air path.

[0102] The rotary disk housing 411, the rotary disk 200, and the isolation plate 4 are enclosed together to form the dehumidification zone 1-1, the regeneration zone 1-2, and the cooling zone 33 independent of each other. The rotary disk housing 411, the rotary disk 200, and the isolation plate 4 are enclosed together to form three independent spaces, i.e., the moisture adsorption zone 1-1, the regeneration zone 1-2, and the cooling zone 33. The three zones are relatively closed, such that their air paths will not affect each other. Therefore, in the arrangement of air paths, air crossing will not occur, which may result in low dehumidification efficiency.

[0103] In order to reduce the temperature of the adsorption material in the cooling zone 33, the temperature of the airflow passing through the cooling zone 33 can be reduced. Generally, the temperature of the outdoor air is lower than the temperature of the airflow in the clothing treatment container. Therefore, in an embodiment of the present application, an open airflow loop may be designed to introduce outside air 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 in communication with the outside, and the cooling zone 33 reduces the temperature of the cooling zone 33 by utilizing the outside air.

[0104] In an embodiment, a first ventilation channel may be included. One end of the first ventilation channel is in communication with the cooling zone 33, and the other end of the first ventilation channel is in communication with the outside, such that an airflow of outside air enters the cooling zone 33 through the first ventilation channel, so as to reduce the temperature of the cooling zone 33.

[0105] Further, in order to speed up air exchange, as shown in FIG. 17, a second fan 8 is further included. The second fan is located in the first ventilation channel and configured to increase an air flow rate between the cooling zone 33 and the outside air, or increase a reduction rate of the temperature of the cooling zone 33. The second fan 8 can increase the flow rate of the airflow, and the airflow can take away the heat from the adsorption medium in the cooling zone 33 when the airflow passes through the adsorption medium, such that the purpose of reducing the temperature in the cooling zone 33 can be achieved. In an embodiment provided by the present application, the second fan 8 is a regeneration fan, i.e., the regeneration fan can be reused, so as to reduce the production cost effectively. Without additionally considering the costs, the second fan 8 may also be a refrigeration fan, which can not only increase the flow rate of the airflow, but also reduce the temperature of the airflow, such that the reduction rate of the temperature in the cooling zone 33 can be effectively increased, thereby achieving the purpose of reducing the temperature in the cooling zone 33.

[0106] In order to reduce the temperature of the airflow passing through the cooling zone 33, a condensation device may be additionally provided, such that the airflow can enter the cooling zone 33 after passing through the condensation device, so as to reduce the temperature of the adsorption medium in the cooling zone 33. Therefore, in an embodiment provided by the present application, as shown in FIGS. 19 and 20, a first condensation device 7 is further included. The first condensation device 7 is located upstream of the intake port of the cooling zone 33 and configured to reduce the temperature of the airflow entering the cooling zone 33 through the first condensation device 7.

[0107] FIG. 19 is a schematic structural diagram of a first condensation device 7, and FIG. 20 is a schematic diagram showing a current position of the first condensation device 7. The first condensation device 7 is arranged on the air path to the cooling zone 33, which can reduce the temperature of the airflow entering the cooling zone 33. Therefore, the first condensation device 7 is located upstream of the intake port of the cooling zone 33.

[0108] FIG. 21 is a schematic diagram of an upper housing of a drying module. The upper housing in FIG. 21 corresponds to the lower housing in FIG. 16, and they may be combined into a complete drying module. The airflow may also come from a dry airflow discharged from an exhaust port of the moisture adsorption zone 1-1. Based on this design, the air path may be designed as a closed-loop structure. As described in the foregoing embodiments, where the airflow entering the cooling zone 33 is from the outside air, an open-loop structure is used. In practice, a closed-loop structure may also be designed. Compared with the open-loop structure, the closed-loop structure can effectively save the layout space due to the limited layout space of the clothing treatment apparatus; and there is no need for a design for a device for filtering the outside air. If the air path is of the open-loop design, it is necessary to consider the part for filtering the air, set the air intake volume, determine the size of the intake port, and ensure that no dust is mixed in the air to affect the effect of the rotary disk, which impose design difficulties. In addition, the rotary disk needs to be regularly cleaned of dust to avoid affecting the service life of the rotary disk. Therefore, the closed-loop design of the airflow can omit the design for a device for filtering the outside air, without additionally adding components for filtering the air, which can effectively control the costs of the product and improve the service life of the product. However, the closed-loop design imposes higher demands on designers. How to properly utilize limited space to arrange various fans and achieve a closed loop of the air path is a technical challenge to be addressed. In the design of the closed-loop air path, it is necessary to pay attention to the arrangement of the airflow in the closed loop on the basis of the existing technologies, and the flow rate of the airflow can be increased by using an apparatus such as a fan, so as to achieve the design of the closed-loop air path. In terms of the arrangement of the air path, the embodiments of the present application are all implemented by using a fan, which will not be repeated hereinafter.

[0109] A specific embodiment where the first condensation device 7 is located upstream of the intake port of the cooling zone 33 may be as follows. After the airflows enter the regeneration zone 1-2 and the cooling zone 33, the heated airflow in the regeneration zone 1-2 and the airflow in the cooling zone 33 enter the first condensation device 7 together, and are cooled by the first condensation device 7. The cooled and dehumidified airflow returns to the regeneration zone 1-2 and the cooling zone 33 with the help of a fan, and the cooling zone 33 is blown by the cooled airflow, thereby reducing the temperature of the cooling zone 33. That is, the airflow in the regeneration zone 1-2 (i.e., the moisture desorption airflow) is heated by the heater, and then desorbs the moisture from the regeneration zone 1-2, while the airflow entering the cooling zone 33 does not need to be heated, but directly enters the cooling zone 33 to cool the cooling zone 33.

[0110] Alternatively, the dry airflow dehumidified in the moisture adsorption zone 1-1 may be directly discharged into the cooling zone 33 for cooling, or the dry airflow dehumidified in the moisture adsorption zone 1-1 may be discharged into the cooling zone 33 for cooling after passing through the condensation device. Therefore, the drying module further includes: a second ventilation channel. One end of the second ventilation channel is in communication with an exhaust port of the regeneration zone 1-2, and the other end of the second ventilation channel is in communication with the intake port of the cooling zone 33; and the first condensation device 7 is located in the second ventilation channel. In this case, the exhaust port of the regeneration zone 1-2 is in communication with the intake port of the cooling zone 33, and the first condensation device 7 is located in the second ventilation channel. That is, the airflow discharged from the regeneration zone 1-2 enters the cooling zone 33 after being subjected to condensation by the first condensation apparatus 7, or the first condensation apparatus 7 is located between the exhaust port of the moisture adsorption zone 1-1 and the intake port of the cooling zone 33, and before the airflow enters the cooling zone 33, the airflow is first subjected to condensation before entering the cooling zone 33, thereby implementing the above technical solution.

[0111] The above technical solution may be as follows. The drying module further includes: a third ventilation channel. One end of the third ventilation channel is in communication with the exhaust port of the moisture adsorption zone 1-1, and the other end of the third ventilation channel is in communication with the intake port of the cooling zone 33. The cooling zone 33 reduces the temperature of the cooling zone 33 by utilizing the airflow discharged from the moisture adsorption zone 1-1 introduced through the third ventilation channel.

[0112] The above technical solution may be as follows. The dry airflow discharged from the moisture adsorption zone 1-1 directly enters the cooling zone 33, and the heat in the cooling zone 33 is taken away by the flow of the air, so as to achieve the cooling of the cooling zone 33.

[0113] Alternatively, the dry airflow discharged from the moisture adsorption zone 1-1 passes through the first condensation device 7 to obtain a low-temperature dry airflow that enters the cooling zone 33, so as to further improve the condensation effect of the cooling zone 33. Alternatively, the airflow discharged from the regeneration zone 1-2 enters the cooling zone 33 after being subjected to condensation by the first condensation device 7.

[0114] Specifically, the air path may be configured as follows. The wet airflow flows out from the outlet port of the clothing treatment container 1, passes through the circulation fan, and is divided into two airflows. One airflow enters the moisture adsorption zone 1-1 through the circulating air path, and the dehumidified airflow 1-1 is discharged into the clothing treatment container 1. The other airflow enters the cooling zone 33 through the cooling air path, heated by the regeneration heater, and then enters the regeneration zone 1-2 to desorb the moisture from the rotary disk; the hot and wet airflow enters the condenser for condensation, and after the condensation, the dry and cold airflow is blown into the regeneration zone 1-2 and the cooling zone 33 by the fan. One airflow is heated by the heater and then subjected to condensation again, and the other airflow enters other regions except the regeneration zone 1-2 from the cooling zone 33, such as the moisture adsorption zone 1-1, the drum, and even the indoor air. In order to reduce the temperature of the cooling zone 33, a technical solution of additionally adding a second condenser may also be adopted. Therefore, the cooling zone 33 further includes: a second condensation device 6 configured to reduce the temperature of the cooling zone 33. If the heater in the regeneration zone 1-2 and the cooler in the cooling zone 33 are arranged on the upper part of the rotary disk 200, devices and an air inlet may be provided on the upper part of the rotary disk 200. One airflow enters the regeneration zone 1-2 through the heater, passes through the condenser, and enters the regeneration zone 1-2 after being heated again, so as to form a closed loop, and the other airflow enters the cooling zone 33, passes through the cooling device, and then merges with the circulating airflow.

[0115] A refrigeration mode of the second condensation device is at least any one of water cooling, air cooling, and semiconductor refrigeration. As shown in FIG. 22, and with reference to the foregoing embodiments, when the second condensation device 6 is located in the cooling zone 33, the cooling zone 33 is cooled by utilizing the low temperature generated by the second condensation device 6, which can be applied to scenarios with narrow space. Therefore, in actual application scenarios, an appropriate second condensation device 6 can be selected according to actual needs, and the position of the second condensation device 6 can be determined, so as to determine an appropriate refrigeration mode.

[0116] The drying module is provided with a dehumidifying air channel and a functional device accommodating region. The functional devices may include a heating device and a cooling device, which may be integrated as a whole or provided separately. The heater may be a heating tube, a heating wire, or a semiconductor heating end, and the cooler may adopt air cooling. If the cooler adopts air cooling, no device may be provided, or a fan, a semiconductor refrigeration end, or the like, may be provided for cooling. The heating device and the cooling device may be provided on an upper part or a lower part of the rotary disk 200, corresponding to the rotary disk 200.

[0117] As shown in FIG. 22, with the regeneration zone 1-2 being provided with a heater as an example, the heater is partially provided with heating tubes, the cooling zone 33 is provided with no heating tube or is provided with other cooling devices, such as small fans or semiconductor refrigeration devices, and an isolation plate 4 is provided between the regeneration zone 1-2 and the cooling zone 33. If no cooling device is provided in the cooling zone 33, the cooling zone 33 may have the heat taken away from the cooling zone 33 by utilizing the airflow that has been subjected to condensation, thereby achieving a cooling effect. As shown in FIG. 22, a cooling device may be further added to the cooling zone 33. The cooling device may adopt at least any one of water cooling, air cooling, and semiconductor refrigeration.

[0118] When the second condensation device 6 in this technical solution adopts water cooling, it may be reused by the airflow discharged from the cooling zone 33. The airflow passing through the second condensation device 6 may also enter the moisture adsorption zone 1-1, so as to improve the condensation and dehumidification effect of the moisture adsorption zone 1-1. Alternatively, when the cooling zone 33 is not additionally provided with a refrigeration device, i.e., when the heat is taken away from the cooling zone 33 by the flow of the airflow, the discharged airflow may be reused by the airflow from the exhaust port of the regeneration zone 1-2, so as to achieve circulation of the closed-loop air path. Those skilled in the art can make a reasonable arrangement according to actual needs. If the refrigeration mode of the second condensation device 6 is air cooling, the second condensation device 6 may be an ordinary fan to achieve air cooling, and may further be a refrigeration fan. That is, the airflow generated by the current fan is a low-temperature airflow, and the low-temperature airflow enters the intake port of the cooling zone 33, such that the cooling zone 33 can be cooled, and the dehumidification capacity of the rotary disk 200 can be improved.

[0119] The second condensation device 6 in the technical solution in this embodiment may also be reused, and a plurality of second condensation devices may be arranged according to actual needs. Those skilled in the art can make a reasonable arrangement according to actual needs, which will not be listed herein. The refrigeration mode of the second condensation device 6 may also be semiconductor refrigeration.

[0120] In order to describe the technical solution in the embodiment of the present application more clearly, the semiconductor refrigeration will be briefly described below. A semiconductor refrigerator refers to a device that obtains cold energy by using the thermoelectric effect of a semiconductor, and is also referred to as a thermoelectric refrigerator. When two different metals are connected by a conductor and a direct current is applied, the temperature at one junction decreases and the temperature at the other junction increases. If the power supply is reversed, the temperatures at the junctions change reversely. This phenomenon is known as the Peltier effect, also known as the thermoelectric effect. The thermoelectric effect of pure metal is small. If the metal is replaced with an N-type semiconductor and a P-type semiconductor, the effect is much greater. After the power is turned on, electron-hole pairs are generated near the upper junction, where the internal energy decreases, the temperature is reduced, and heat is absorbed from the environment, such that the upper junction is called a cold end. At the other end, due to recombination of electron-hole pairs, the internal energy increases, the temperature is increased, and heat is released to the environment, such that the other end is called a hot end. A single pair of semiconductor thermoelectric elements generate a small temperature difference and little cold energy. A practical semiconductor refrigerator is formed by combining a plurality of pairs of thermoelectric elements in parallel and in series, and is also referred to as a thermopile. A single-stage thermopile can achieve a temperature difference of about 60° C., and the temperature of the cold end can reach −10° C. to −20° C. Increasing the number of stages of the thermopile can increase the temperature difference across the ends. However, the number of stages should not be too large, and is generally 2 to 3. Generally, semiconductor refrigeration achieves a good refrigeration effect and does not occupy much space, but it requires high power consumption. Therefore, those skilled in the art can select a corresponding refrigeration unit according to actual needs.

[0121] Of course, there may be one or more second condensation devices 6, and a single clothing treatment apparatus may adopt a number of refrigeration modes, such as both semiconductor refrigeration and air cooling, or all of semiconductor refrigeration, air cooling, and water cooling, which can be reasonably selected according to a current application scenario. If the above technical solution is adopted, the arrangement of the air path may also be as follows. The wet airflow may be divided into two airflows after exiting the fan through the outlet pipeline, or may be divided into two airflows immediately after exiting the exhaust port of the clothing treatment container 1. A cooling channel may be provided on the outlet pipeline, such as in a water cooling or air cooling mode, and the airflow enters the cooling zone 33 after being cooled through the cooling channel, thereby improving the cooling efficiency of the cooling zone 33. Meanwhile, the pre-condensation of the outlet channel may reuse a filter screen to self-clean the water outlet pipeline, thereby further improving the dehumidification efficiency.

[0122] Optionally, the drying module further includes: a fourth ventilation channel. One end of the fourth ventilation channel is in communication with the exhaust port of the cooling zone 33, and the other end of the fourth ventilation channel is in communication with the intake port of the regeneration zone 1-2, such that the airflow discharged from the cooling zone 33 enters the regeneration zone 1-2 through the fourth ventilation channel. The airflow discharged from the exhaust port of the cooling zone 33 will retain some heat from the cooling zone 33. Therefore, the temperature of the airflow discharged from the exhaust port of the cooling zone 33 will be higher than that of the air at the intake port of the cooling zone 33. The air from the cooling zone 33 can be directly discharged into the drum (clothing treatment container 1). In order to save energy, the air from the cooling zone 33 can also be discharged into the regeneration zone 1-2.

[0123] The regeneration zone 1-2 utilizes heating to remove the moisture from the rotary disk 200, so as to restore the moisture adsorption capacity of the rotary disk. Therefore, the airflow entering the regeneration zone 1-2 is usually a heated airflow, and when the airflow enters the regeneration zone 1-2, the airflow is usually heated by a device such as a regeneration heater. Therefore, in the embodiments of the present application, when the closed-loop air path is designed, the airflow discharged from the exhaust port of the cooling zone 33 is sent into the regeneration heater under the action of the fan and then enters the regeneration zone 1-2, such that energy consumption can be partially reduced, and the airflow discharged from the cooling zone 33 is sent into the regeneration zone 1-2 to take advantage of the high temperature of that part of the airflow.

[0124] In the technical solution in the embodiment of the present application, the temperature of the airflow discharged from the cooling zone 33 is utilized and the airflow is reused in the regeneration zone 1-2. The regeneration zone 1-2 requires a heated airflow for removing the moisture from the rotary disk, so as to restore the moisture adsorption capacity of the rotary disk. Therefore, the reused airflow can appropriately reduce the energy consumption required by the airflow to be heated, thereby saving energy. In addition, the temperature of the airflow discharged from the cooling zone 33 is reused in the regeneration zone 1-2, which also increases the temperature of the regeneration zone 1-2, thereby improving the heating effect of the regeneration zone 1-2. The improvement of the heating effect allows to speed up the removal of the moisture from the rotary disk 200, thereby improving the moisture adsorption capacity of the rotary disk 200.

[0125] As shown in FIG. 27, the drying module includes: the rotary disk housing 411 accommodating the moisture adsorption-desorption member, where a heater mounting part is provided on the rotary disk housing 411; the heating device 30 mounted to the heater mounting part; and a sealing assembly 50, where the sealing assembly 50 is provided between the heating device 30 and the rotary disk housing 411, the sealing assembly 50 is in a hollow annular shape, a first sealing body 521 is in contact with the heating device 30, and a second sealing body 522 is in contact with the rotary disk housing 411.

[0126] In some embodiments, the rotary disk housing 411 accommodating the moisture adsorption-desorption member may be of a circular structure. A moisture adsorption zone and a dehumidification zone may be provided on the rotary disk housing 411. The moisture adsorption zone and the dehumidification zone are formed by separating the rotary disk housing 411 by at least two radially arranged ribs. The heater mounting part is provided in the dehumidification zone of the rotary disk housing 411, which facilitates modular assembly of the heating device 30. The shape of the heating device 30 matches the shape of the dehumidification zone. The dehumidification zone is a sector-shaped zone, and then the heating device 30 is of a sector-shaped structure. The heating device 30 may include a space enclosed by a top wall, two side walls along the radial direction, an inner arc side wall, and an outer arc side wall. A heating member is arranged in the space, the bottom of the heating device 30 may be empty, and the air inlet may be provided on the outer arc side wall, such that the dry low-temperature regeneration airflow enters the air inlet, passes through the heating member and becomes heated, and then flows down to the moisture adsorption-desorption member. The moisture adsorption-desorption member may include a rotary disk, and the rotary disk may adsorb, in the moisture adsorption zone, moisture in the wet circulating airflow from the drum, such that the wet circulating airflow can be turned into a dry circulating airflow, and the dry circulating airflow enters the drum through the intake port of the drum and is in full contact with the clothing, thereby improving the drying efficiency and reducing the energy consumption. The rotary disk is configured to be rotatable relative to the rotary disk housing 411. When the rotary disk rotates to the dehumidification zone, the hot regeneration airflow desorbs moisture from a part of the rotary disk located in the dehumidification zone.

[0127] Therefore, during circumferential rotation of the rotary disk, the rotary disk cyclically passes through the moisture adsorption zone and the dehumidification zone to continuously adsorb moisture and desorb moisture, such that the rotary disk always has a good moisture adsorption capacity, thereby improving the efficiency and effect of moisture adsorption of the rotary disk. The sealing assembly is located between the heating device 30 and the rotary disk housing 411. In order to enable the hot regeneration airflow to pass smoothly, the sealing assembly is configured in a hollow annular shape, and the shape of the sealing assembly matches those of the heating device 30 and the rotary disk housing 411, such that the assembly of the sealing assembly is easy to operate. The sealing assembly 50 may include a support member 51 and a sealing gasket 52. The support member 51 is of an L-shaped structure along the cross section tangent to the length of the support member 51. The sealing gasket 52 includes a first sealing body 521 and a second sealing body 522. The first sealing body 521 and the second sealing body 522 are separately arranged at two sides of the L-shaped structure. A part of the support member 51 is exposed outside the sealing gasket 52, and the exposed part of the support member 51 is in contact with the hot regeneration airflow to prevent heat of the hot regeneration airflow from being directly transferred to the sealing gasket 52. The sealing gasket 52 may be made of a foam material, a silica gel material, or a soft rubber material. Preferably, the sealing gasket 52 is made of the silica gel material, such that the sealing gasket 52 can remain soft and elastic regardless of a high temperature or a low temperature, and has good sealing performance. The support member 51 may be made of a heat insulation material or a metal material. Preferably, the support member 51 may be made as a plain carbon steel sheet metal part, which can not only improve the strength of the support member 51, but also provide a certain heat insulation effect. The cross section of the support member 51 is of an L-shaped structure, which can improve the strength of the support member 51, and facilitate the arrangement of the second sealing body 522 and the first sealing body 521 on the inner and outer side surfaces of the L-shaped structure, respectively. For example, the first sealing body 521 may be in contact with the heating device 30, the second sealing body 522 may be in contact with the rotary disk housing 411, and the support member 51 may be located between the first sealing body 521 and the second sealing body 522, such that the heat generated by the heating device 30 can be buffered to avoid damage to the rotary disk housing 411 caused by heat directly transferred to the rotary disk housing, thereby delaying aging of the rotary disk housing 411 and increasing the service life of the drying module. In addition, the heat generated by the heating device 30 heats the regeneration airflow to obtain a hot regeneration airflow, so as to desorb moisture from a part of the moisture adsorption-desorption member. The outer side of the bent part of the support member 51 may not be provided with the first sealing body 521 and is exposed outside the sealing gasket 52. The exposed part is in contact with the hot regeneration airflow to prevent the heat of the hot regeneration airflow from being directly transferred to the second sealing body 522 provided on the inner side surface of the L-shaped structure. The second sealing body 522 seals the peripheral side of the heater mounting part of the rotary disk housing 411 to prevent the hot regeneration airflow from leakage, thereby improving the drying efficiency of the drying module.

[0128] In some examples, as shown in FIGS. 23-26, the sealing assembly of the drying module includes the support member 51 and the sealing gasket 52. At least a part of the support member 51 is of an L-shaped structure, that is, the support member may be of an L-shaped structure along the cross section tangent to the length of the support member 51. The sealing gasket 52 includes the first sealing body 521 and the second sealing body 522. The first sealing body 521 and the second sealing body 522 are separately arranged at two sides of the L-shaped structure. At least a part of the support member 51 is exposed outside the sealing gasket 52, and the exposed part of the support member 51 is in contact with the hot regeneration airflow to prevent heat of the hot regeneration airflow from being directly transferred to the sealing gasket 52. The sealing gasket 52 may be made of a foam material, a silica gel material, or a soft rubber material. Preferably, the sealing gasket 52 is made of the silica gel material, such that the sealing gasket 52 can remain soft and elastic regardless of a high temperature or a low temperature, and has good sealing performance. The support member 51 may be made of a heat insulation material or a metal material. Preferably, the support member 51 may be made as a plain carbon steel sheet metal part, which can not only improve the strength of the support member 51, but also provide a certain heat insulation effect. The cross section of the support member 51 is of an L-shaped structure, which can improve the strength of the support member 51, and facilitate the arrangement of the second sealing body 522 and the first sealing body 521 on the inner and outer side surfaces of the L-shaped structure, respectively. For example, the first sealing body 521 may be in contact with the heating device 30, the second sealing body 522 may be in contact with the rotary disk housing 411, and the support member 51 may be located between the first sealing body 521 and the second sealing body 522, such that the heat generated by the heating device 30 can be buffered to avoid damage to the rotary disk housing 411 caused by heat directly transferred to the rotary disk housing, thereby delaying aging of the rotary disk housing 411 and increasing the service life of the drying module. In addition, the heat generated by the heating device 30 heats the regeneration airflow to obtain a hot regeneration airflow, so as to desorb moisture from a part of the moisture adsorption-desorption member. The outer side of the bent part of the support member 51 may not be provided with the first sealing body 521 and is exposed outside the sealing gasket 52. The exposed part is in contact with the hot regeneration airflow to prevent the heat of the hot regeneration airflow from being directly transferred to the second sealing body 522 provided on the inner side surface of the L-shaped structure. The second sealing body 522 seals the peripheral side of the heater mounting part of the rotary disk housing 411 to prevent the hot regeneration airflow from leakage, thereby improving the drying efficiency of the drying module.

[0129] In some embodiments, the support member 51 includes a first edge 511 and a second edge 512 connected to the first edge 511, so as to form the L-shaped structure. A side surface portion of the first edge 511 or the second edge 512 is exposed to the sealing gasket 52. Specifically, the support member 51 may be formed by stamping a plain carbon steel sheet metal part, such that a certain strength and stiffness can be achieved with a thinner support member 51, and the support member can withstand the impact of the high-speed flow of the hot regeneration airflow, thereby obtaining a durable sealing assembly with a low manufacturing cost. For example, the outer side surface portion at the second edge 512 is exposed to the sealing gasket 52, and the exposed part is in contact with the hot regeneration airflow, so as to prevent the heat of the hot regeneration airflow from being directly transferred to the second sealing body 522 arranged on the inner side surface of the second edge 512. The second sealing body 522 seals the peripheral side of the rotary disk housing 411 to prevent the hot regeneration airflow from leakage, thereby improving the drying efficiency of the drying module.

[0130] In some embodiments, the first sealing body 521 at least partially covers one side of the first edge 511 or the second edge 512, and the second sealing body 522 at least partially covers the other opposite side of the first edge 511 and the second edge 512. For example, the second sealing body 522 may be arranged on the inner side surface of the L-shaped structure, the first sealing body 521 may be arranged on the outer side surface of the L-shaped structure, the first sealing body 521 may be in contact with the heating device 30, and the second sealing body 522 may be in contact with the rotary disk housing 411.

The arrangement of the protrusion 523 facilitates the contact with the heating device 30, and a good fit to the heating device 30 can be achieved through the deformation of the protrusion 523, so as to ensure the air tightness of the system.

[0132] In some embodiments, the protrusion 523 includes a first sealing strip and a second sealing strip that is symmetrical with and spaced apart from the first sealing strip, the first sealing strip and the second sealing strip are both arranged obliquely, and a spacing distance between the first sealing strip and the second sealing strip gradually increases from the first sealing body 521 in a direction away from the second sealing body 522. The first sealing strip and the second sealing strip are arranged obliquely and can be spaced apart on the first sealing body 521. When the sealing assembly is closely attached to the heating device 30, the first sealing strip and the second sealing strip are deformed and tightly fitted to the heating device 30. The first sealing strip and the second sealing strip are both arranged obliquely from the first sealing body 521 in a direction away from each other, and the spacing distance between the first sealing strip and the second sealing strip gradually increases, such that two sealed connections can be formed between the first sealing strip and the second sealing strip and the heating device 30, thereby further ensuring the air tightness of the system.

[0133] In some embodiments, the connection of the first edge 511 and the second edge 512 is a circular arc transition. An included angle between the first edge 511 and the second edge 512 is set to be greater than or equal to 90 degrees. In this way, the strength of the support member 51 can be improved, thereby improving the overall strength of the sealing assembly, and making the sealing assembly durable. In some embodiments, an end surface of the second sealing body 522 protrudes from the first edge 511 or the second edge 512. For example, the second sealing body 522 is set to have a height slightly larger than that of the second edge 512, and the end surface of the second sealing body 522 may be in contact with the moisture adsorption-desorption member to achieve the air tightness of the system.
