[0002] The present disclosure relates to the technical field of electrical appliances, and in particular, to a clothing treatment apparatus.BACKGROUND

[0003] Driven by factors such as people's pursuit of a healthy and high-quality life and the increasingly fast-paced urban living, an all-in-one washing and drying machine has emerged and gained wide popularity among consumers. The all-in-one washing and drying machine is especially suitable for families in the south during the plum rain season, families in the north where the poor air quality makes it unsuitable for outdoor drying of clothes, and users who want to wear clothes immediately after washing or pursue more fluffy and comfortable clothes.

[0004] Most of the existing clothing treatment apparatuses with a drying function use an evaporator to heat and absorb moisture of humid air in an inner drum of a washing and drying machine to obtain high-temperature air, and then make the high-temperature air re-enter the inner drum of the washing and drying machine, such that moisture in the clothes is evaporated. However, the overall temperature of the evaporator is consistent. During the evaporation of the humid air, the moisture adsorption capacity of the evaporator for the humid air decreases, resulting in low moisture adsorption efficiency, long drying time, and high power consumption. In addition, there are also some methods to directly dehumidify the humid airflow through spraying with condensed water or using a condenser, but the airflow processed in this method still contains a high proportion of moisture, and recycling also requires "heating, cooling, dehumidification, and reheating" of the airflow, resulting in low dehumidification efficiency and high power consumption.

[0005] Therefore, there is an urgent need to design a clothing treatment apparatus to overcome the above defects, such that the power consumption is reasonable and the drying effect is better.SUMMARY

[0006] In order to overcome the above defects, the present disclosure provides a clothing treatment apparatus with a drying function, which can achieve reasonable power consumption and a better drying effect.

[0007] The clothing treatment apparatus according to the present disclosure includes: a drying module and a drum, where the drum has at least one drum air outlet and at least one drum air inlet, and the drum air outlet and the drum air inlet are in airflow communication with the drying module separately to form a drying airflow path; the drying module includes: a first drying module housing having a first space, a second drying module housing having a second space, and a moisture adsorption-desorption member disposed between the first drying module housing and the second drying module housing; the second space at least includes a dehumidification area 3b and a regeneration area 3a, and the dehumidification area 3b is provided with a first airflow inlet; at least part of the moisture adsorption-desorption member periodically passes through the dehumidification area 3b and the regeneration area 3a; and a distance is provided in a vertical direction from a bottom plate of the second drying module housing to a corresponding surface of the moisture adsorption-desorption member, and in the dehumidification area 3b, a distance near the first airflow inlet is different from a distance of at least part of other positions distal to the first airflow inlet.

[0008] In the clothing treatment apparatus according to the present disclosure, a part of a space formed by the second drying module housing and the moisture adsorption-desorption member is disposed as follows: the distance is provided in the vertical direction from the bottom plate of the second drying module housing to the corresponding surface of the moisture adsorption-desorption member, and in the dehumidification area 3b, the distance near the first airflow inlet is different from the distance of the at least part of other positions distal to the first airflow inlet, thereby enabling the shape of the air path to be converged in the direction of the airflow, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow, the pressure and flow rate of the airflow can remain stable, and the airflow can be fully in contact with the moisture adsorption-desorption member. Therefore, the moisture adsorption-desorption member can achieve a better adsorption effect on the drying airflow flowing therein.BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] As used herein, the term "regeneration" refers to the return of an otherwise relatively dry object to a relatively dry state by at least partial dehumidification after the adsorption of moisture. The terms "upstream" and "downstream" are used to indicate the relative position of a second element encountered by an airflow after the airflow flows through a first element when flowing in a flow path originating at a system air inlet, where the first element is the "upstream" of the second element and the second element is the "downstream" of the first element.

[0012] As shown in FIGs. 1 to 4, 14, and 17, the present disclosure provides a clothing treatment apparatus 1. The clothing treatment apparatus includes a drying module 3 and a drum 2. The drum 2 has at least one drum air outlet 202 and at least one drum air inlet 203, and the drum air outlet 202 and the drum air inlet 203 are in airflow communication with the drying module 3 separately to form a drying airflow path. The drying module 3 is disposed above the drum 2 and includes a first air outlet 32 and a first air inlet 33. The drying module is in communication with the drum air outlet 202 through the first air inlet 33 and in communication with the drum air inlet 203 through the first air outlet 32. Based on this, the drying module 3 and the drum 2 form a circulation path, so as to realize the drying of the humid and hot air circulating therein.

[0013] In the drying mode, the drying airflow is guided from the drum 2 to the drying module 3 through the first air inlet 33 of the drying module 3. The drying module 3 dehumidifies and heats the drying airflow from the drum 2, and then the drying airflow is guided back to the drum 2 through the first air outlet 32 of the drying module 3. This process is repeated to dry the clothes.

[0014] As shown in FIG. 4, the drying module 3 includes a first drying module housing 310, a second drying module housing 320, and a moisture adsorption-desorption member 300. The moisture adsorption-desorption member 300 may be made of a material with good moisture adsorption performance and good desorption performance, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The moisture adsorption-desorption member 300 may also be provided in different shapes, such as a circular rotary disk, a strip-shaped moisture adsorption belt, and containers with openings of different shapes. In addition, when the moisture adsorption-desorption member 300 is a rotary disk, the drying module 3 may further include a driving assembly. The driving assembly may include a motor, and the motor may drive the rotary disk to rotate.

[0015] It can be understood that the pore size of the moisture adsorption-desorption member 300 generally represents the diameter of the pore structure of the member. When the shape of the pore is regular, such as a rectangle, triangle, circular, ellipse, or corrugated pore shape, correspondingly, the pore size may be the side length of the rectangle, the height of the triangle, the diameter of the circle or ellipse, the wave height of the corrugated pore. In some embodiments, the pore size may be characterized by a wave height in the moisture adsorption-desorption member, such as a wave height of a corrugated pore shape. The pore size may also be characterized by a diameter of a circumscribed circle of the moisture adsorption pore of the moisture adsorption-desorption member.

[0016] Referring to FIG. 6, the first drying module housing 310 has a first space, the second drying module housing 320 has a second space, and the moisture adsorption-desorption member 300 is disposed between the first drying module housing 310 and the second drying module housing 320. A gap is provided between a first surface 3001 of the moisture adsorption-desorption member 300 and a part of a top wall of the first drying module housing 310 to form a first airflow channel. A gap is provided between a second surface 3002 of the moisture adsorption-desorption member and a part of a bottom plate of the second drying module housing 320 to form a second airflow channel. The second airflow channel, the moisture adsorption-desorption member 300, and the first airflow channel form the airflow path. The second drying module housing 320 includes a second drying module housing bottom plate 3201 and a circumferential side wall protruding from the bottom plate, and a recess portion formed therein is the second space. In the second space, two second partition members 321 are disposed radially along the second drying module housing 320 to separate the second space into a dehumidification area 3b and a regeneration area 3a. Therefore, it is beneficial for the moisture adsorption-desorption member 300 to cyclically pass through the dehumidification area 3b and the regeneration area 3a during the rotation of the moisture adsorption-desorption member to continuously absorb and desorb moisture, such that the moisture adsorption-desorption member 300 has a good water adsorption capacity, thereby improving the efficiency and effect of moisture adsorption. In some embodiments, the two second partition members 321 are arranged in a V shape, and the dehumidification area 3b and the regeneration area 3a are substantially fan-shaped.

[0017] Referring to FIG. 5, the first drying module housing 310 includes a first drying module housing top wall 3101 and a circumferential side wall, and a recess portion formed therein is the first space. At positions corresponding to the two second partition members 321 in the first space, two first partition members 311 are correspondingly disposed radially along the first drying module housing to separate the first space into the dehumidification area 3b and the regeneration module mounting area 3c. The recess portion structure of the first drying module housing 310 is disposed opposite to that of the second drying module housing 320, and when the first drying module housing 310 and the second drying module housing 320 are connected in a fitting manner, the first space and the second space can form an accommodating cavity of the moisture adsorption-desorption member 300. Since an airflow passes through the accommodating cavity of the moisture adsorption-desorption member 300, the first drying module housing 310 and the second drying module housing 320 can be connected in a sealed manner. The moisture adsorption-desorption member 300 is located between the second partition member 311 and the first partition member 321. In order to prevent the drying airflow and the regeneration airflow discharged from the drum from crossing each other, the second partition member 321 and the first partition member 311 both can form dynamic sealing with the moisture adsorption-desorption member 300, which is beneficial for the moisture adsorption-desorption member 300 to pass through the dehumidification area 3b and the regeneration area 3a during the rotation of the moisture adsorption-desorption member to continuously absorb moisture and undergo dehydration and drying, such that the moisture adsorption-desorption member 300 always has a good water adsorption capacity, thereby improving the efficiency and effect of moisture adsorption. In some embodiments, the two first partition members 311 are arranged in a V shape, and the dehumidification area 3b and the regeneration module mounting area 3c are substantially fan-shaped.

[0018] It should be noted that the partition member referred to herein refers to each individual partition member radially connected from a circumferential side wall of the first drying module housing 310 or the second drying module housing 320 to a central position of the housing. The at least two first partition members 311 and the at least two second partition members 321 may be integrally formed, or may be separately manufactured and mounted. This manufacturing manner does not affect the definition of the partition member.

[0019] As shown in FIGs. 4 to 6, the second space is provided with a first airflow inlet 301, and the first space is provided with a first airflow outlet 304. The drying airflow passes through the first airflow inlet 301, sequentially passes through the second space, the moisture adsorption-desorption member 300, and the first space, and finally flows out through the first airflow outlet 304.

[0020] FIG. 7(a) is a schematic sectional view of a dehumidification area 3b when a drying module is horizontally disposed according to the present disclosure. It should be noted that the schematic view is a schematic illustration of the sectional structure, and the schematic view is only used to illustrate a structure of the dehumidification area 3b, and does not represent an actual shape. As shown in FIG. 7(a), the second drying module housing 320 has the second space 3202, and in the dehumidification area 3b of the second space 3202, a distance d is provided in a vertical direction from the second drying module housing bottom plate 3201 to a second surface 3002 of the moisture adsorption-desorption member. In the second space 3202, a distance d near the first airflow inlet 301 is different from a distance d of at least part of other positions distal to the first airflow inlet 301, as viewed in an overall flow direction of the drying airflow in the second space 3202.

[0021] It can be understood that the "overall flow direction" of the drying airflow in the second space 3202 refers to the general flow direction of the drying airflow formed by the airflow flowing through a space between the second surface 3002 of the moisture adsorption-desorption member and the second drying module housing bottom plate 3201, when the airflow is viewed as a whole, i.e., the general direction from the first airflow inlet 301 to the first airflow outlet 304, as shown by arrows in FIG. 6. It should be noted that, in the second space 3202, the flow direction of a small part of the drying airflow is different from the overall flow direction. For example, the drying airflow passes through the moisture adsorption-desorption member 300 from the second space 3202 to the first space 3102, but the part of the drying airflow does not cause a change in the "overall flow direction".

[0022] Through this arrangement, the shape of the air path through which the drying airflow flows can be converged, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow.

[0023] In some embodiments, in the dehumidification area 3b, a distance d at the first airflow inlet 301 is larger than a distance d of at least part of positions distal to the first airflow inlet 301, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0024] In some embodiments, in the dehumidification area 3b, the distance d gradually decreases from the first airflow inlet 301 in a direction gradually away from the first airflow inlet 301, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0025] In some embodiments, the second surface 3002 of the moisture adsorption-desorption member is substantially a plane, and in the second space 3202, an included angle in a range of 0° to 45° is formed between a plane where the second drying module housing bottom plate 3201 is located and a plane where the second surface 3002 of the moisture adsorption-desorption member is located. Preferably, an included angle in a range of 5° to 15° is formed between a plane where at least part of the second drying module housing bottom plate 3201 is located and the plane where the second surface 3002 of the moisture adsorption-desorption member is located.

[0026] In some embodiments, near the first airflow inlet 301 of the second space 3202, the distance is between 15 mm and 50 mm; and at the position farthest from the first airflow inlet 301, the distance is between 8 mm and 40 mm. At the first airflow inlet 301 of the second space 3202, the distance is preferably between 20 mm and 40 mm; and at the position farthest from the first airflow inlet 301, the distance is preferably between 10 mm and 26 mm. The farthest position here refers to an end position of the moisture adsorption area of the second space 3202, i.e., a boundary position between the moisture adsorption area and the regeneration area 3a, in the overall flow direction of the drying airflow in the second space 3202.

[0027] Through the above embodiments, the shape of the air path through which the drying airflow flows can be converged, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow, the pressure and flow rate of the airflow can remain stable, and the airflow can be fully in contact with the moisture adsorption-desorption member 300.

[0028] The technical solution according to the present disclosure can achieve a relatively uniform adsorption effect of the drying airflow in various parts of the moisture adsorption-desorption member 300.

[0029] In addition, as shown in FIG. 7(b), the first drying module housing 310, the moisture adsorption-desorption member 300, and the second drying module housing 5320 may also be disposed vertically, and the structure and the implemented drying principle are in one-to-one correspondence with the first drying module housing 310, the moisture adsorption-desorption member 300, and the second drying module housing 320 disposed horizontally in FIG. 7(a), and details are not described herein again.

[0030] It should be noted that, although as shown in FIGs. 7(a) and 7(b), the first drying module housing top wall 3101 and the second drying module housing bottom plate 3201 may gradually incline and extend after a certain distance from the first airflow inlet 301, in other embodiments, the first drying module housing top wall 3101 and / or the second drying module housing bottom plate 3201 may directly inclines and extends near the first airflow inlet 301.

[0031] In addition, although as shown in FIGs. 7(a) and 7(b), the first drying module housing 310 and the second drying module housing 320 each have a bottom plate or a top wall that gradually inclines and extends. However, in practice, only the first drying module housing 310 may have the first drying module housing top wall 3101 that gradually inclines and extends, or only the second drying module housing 320 may have the second drying module housing bottom plate 3201 that gradually inclines and extends.

[0032] In addition, as shown in FIG. 4, the drying module further includes a regeneration module 31, connected to the first drying module housing 310 in a fitting manner. A substantially fan-shaped regeneration module accommodating portion is formed on the first drying module housing 310. The regeneration module 31 is mounted on the regeneration module accommodating portion, the regeneration module 31 is located above the moisture adsorption-desorption member 300, and the regeneration module 31 is configured to, for example, heat the regeneration airflow to desorb the moisture absorbed by the moisture adsorption-desorption member 300. The regeneration module 31 may include a heating assembly for heating the regeneration airflow, and the moisture adsorption-desorption member 300 passes through the dehumidification area and the regeneration area during rotation, so as to continuously perform a cycle process of absorbing moisture and desorbing moisture. Preferably, the heating assembly may be an element having a heating function, such as an electric heating wire or a PTC heater.

[0033] In some embodiments, the area of the dehumidification area 3b of the second space 3202 is larger than or equal to the area of the regeneration area 3a, and a ratio of the area of the dehumidification area 3b to the area of the regeneration area 3a is approximately 5:1 to 1:1.

[0034] In some embodiments, a circulating fan 6 is further provided between the first air inlet 33 of the drying module and the drum air outlet 202, which can accelerate the flow speed of the circulating moisture adsorption airflow. A rotation speed of the circulating fan 6 may be adjusted according to the drying process.

[0035] In some embodiments, the rotation speed of the circulating fan 6 may be adjusted according to the airflow temperature at the first air outlet 32 of the drying module.

[0036] As shown in FIGs. 1 and 2, the drying module 3, the first air inlet 33, and the first air outlet 32 are all located at the top of the clothing treatment device. Such an arrangement method can make full use of the upper space of the drum 2, making the overall arrangement of the clothing treatment device compact.

[0037] As shown in FIG. 6, the second drying module housing 320 in the moisture adsorption area of the second space 3202 is further provided with a flow dividing member 322 in the flow direction of the drying airflow. The flow dividing member 322 is configured to divide the drying airflow flowing in the moisture adsorption area. Specifically, one or more flow dividing members 322 may be provided. When there are two or more flow dividing members 322, the flow dividing members may be disposed in an offset manner, to separate the space into a plurality of flow dividing areas. By providing the flow dividing members 322 on the second drying module housing bottom plate 3201, the drying airflow flowing into the moisture adsorption area of the second space 3202 can be divided. One part enters the area proximal to the center of the circle, and another part enters the area proximal to the periphery of the moisture adsorption-desorption member 300, such that the drying airflow flowing into the circulation path is more dispersed and uniform, and the airflow can be in contact with the moisture adsorption-desorption member 300 in a larger area, thereby improving the moisture adsorption efficiency of the moisture adsorption-desorption member 300.

[0038] In one embodiment as shown in FIG. 8(a), the first drying module housing 320, the moisture adsorption-desorption member 300, and the second drying module housing 310 are horizontally disposed. In the regeneration area 3a, a gap is formed between the first surface 3001 of the moisture adsorption-desorption member 300 and at least part of the second drying module housing 310 to form a third space 3302, and a gap is formed between the second surface 2002 of the moisture adsorption-desorption member 300 and at least part of the first drying module housing 320 to form a fourth space 3402.

[0039] In the regeneration area 3a, the first drying module housing top wall 3101 is parallel or substantially parallel to the first surface 3001 of the moisture adsorption-desorption member in the flowing direction of the airflow, and the second drying module housing bottom plate 3201 is parallel or substantially parallel to the second surface 3002 of the moisture adsorption-desorption member, such that the heights of the third space 3302 and the fourth space 3402 remain unchanged. By disposing the first drying module housing top wall 3101 in the fan-shaped area of the regeneration area 3a and the first surface 3001 of the moisture adsorption-desorption member, and the second drying module housing bottom plate 3201 and the second surface 3002 of the moisture adsorption-desorption member to be parallel to each other, the flow height of the drying airflow remains unchanged, such that the heat received by each part of the moisture adsorption-desorption member 300 rotating through the regeneration area 3a is uniform, achieving substantially the same regeneration effect, while avoiding the local overheating of the regeneration area 3a.

[0040] In one embodiment as shown in FIG. 8(b), the first drying module housing 320, the moisture adsorption-desorption member 300, and the second drying 5 module housing 310 may be disposed vertically.

[0041] Through this vertical arrangement, in the regeneration area 3a, a distance between the first drying module housing top wall 3101 and a corresponding surface of the moisture adsorption-desorption member and a distance between the second drying module housing bottom plate 3201 and a corresponding surface of the moisture adsorption-desorption member also remain unchanged.

[0042] In addition, as shown in FIG. 9, at a position of the dehumidification area 3b of the first space proximal to the first air outlet 304, a section of inclined wall 3103 is radially disposed, and the inclined wall 3103 is smoothly and gradually away from the first surface 3001 of the moisture adsorption-desorption member, such that the first drying module housing top wall 3101 forms an approximate step shape in a direction in which the inclined wall 3103 extends.

[0043] The second drying module housing 320 includes a second drying module housing bottom plate 3201 and a circumferential side wall protruding from the bottom plate 3201, and a recess portion formed therein is a second space. Three second partition members 321 are disposed in the second space to separate the second space into a dehumidification area 3b, a cooling area, and a regeneration area 3a. Accordingly, the first drying module housing 310 includes a first drying module housing top wall 3101 and a circumferential side wall, and a recess portion formed therein is the first space. At positions in the first space 3102 corresponding to the three second partition members 321, three first partition members 311 are correspondingly disposed radially along the first drying module housing 310 to separate the first drying module housing 310 into a dehumidification area 3b, a cooling area, and a regeneration module mounting area 3c. A recess portion structure of the first drying module housing 310 is disposed opposite to that of the second drying module housing 320, such that the first drying module housing 310 and the second drying module housing 320 are connected in a sealed manner. The moisture adsorption-desorption member 300 is configured to absorb the moisture in the circulating airflow in the moisture adsorption area, cool the moisture adsorption-desorption member 300 in the cooling area, and desorb the moisture absorbed in the moisture adsorption area through the moisture desorption airflow in the regeneration area 3a during rotation. Preferably, the dehumidification area 3b, the cooling area, the regeneration area 3a, and the regeneration module mounting area 3c are substantially fan-shaped. Similarly, a regeneration module 31 is mounted in the regeneration module mounting area 3c in this embodiment. The structure and the mounting manner of the regeneration module 31 are the same as those described above, and details are not described herein again.

[0044] In some embodiments, the area of the dehumidification area 3b of the second space 3202 is larger than or equal to the area of the cooling area and the area of the regeneration area 3a, and a ratio of the area of the dehumidification area 3b to the area of the cooling area and the area of the regeneration area 3a is approximately 4:1:1 to 1:1:1.

[0045] In some other embodiments, a structure of the clothing treatment apparatus 1 is substantially the same as that in Example 1, and details are not described herein again.

[0046] In some other embodiments, the second space 3202 has a first airflow inlet 301, and the drying airflow passes through the first airflow inlet 301 and sequentially passes through the second space 3202, the moisture adsorption-desorption member 300, and the first space 3102. In the moisture adsorption area, an area of a cross section of at least part of positions distal to the first airflow inlet 301 is different from an area of a cross section at the first airflow inlet 301, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0047] It can be understood that the "overall flow direction" of the drying airflow in the second space 3202 refers to the general flow direction of the drying airflow formed by the airflow flowing through a space between the second surface 3002 of the moisture adsorption-desorption member and the second drying module housing bottom plate 3201, when the airflow is viewed as a whole, i.e., the general direction from the first airflow inlet 301 to the first airflow outlet 304, which may be shown by arrows in FIG. 6. It should be noted that, in the second space 3202, the flow direction of a small part of the drying airflow is different from the overall flow direction. For example, the drying airflow passes through the moisture adsorption-desorption member 300 from the second space 3202 to the first space 3102, but the part of the drying airflow does not cause a change in the "overall flow direction".

[0048] Through this arrangement, the shape of the air path through which the drying airflow flows can be converged, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow.

[0049] In some embodiments, in the moisture adsorption area, an area of a cross section at the first airflow inlet 301 is larger than an area of a cross section at least partially distal to the first airflow inlet 301, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0050] In some embodiments, in the moisture adsorption area, the area of the cross section gradually decreases from the first airflow inlet 301 in a direction gradually away from the first airflow inlet 301, as viewed in the overall flow direction of the drying airflow in the second space.

[0051] In some embodiments, in the dehumidification area 3b, at least part of the second drying module housing bottom plate 3201 gradually inclines upward and extends, such that a cross section of the second space 3202 in a radial direction of the moisture adsorption-desorption member 300 is substantially a right-angled trapezoid, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0052] It can be understood that the "cross section" referred to herein refers to a vertical cross section of a space formed between the second drying module housing bottom plate 3201, the side wall, and the corresponding surface of the moisture adsorption-desorption member 300, as viewed in the overall flow direction of the drying airflow in the second space 3202.

[0053] Through the above embodiments, the shape of the air path through which the drying airflow flows can be converged, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow, the pressure and flow rate of the airflow can remain stable, and the airflow can be fully in contact with the moisture adsorption-desorption member 300.

[0054] The technical solution of the present disclosure can achieve a relatively uniform adsorption effect of the drying airflow in various parts of the moisture adsorption-desorption member 300.

[0055] In summary, in the clothing treatment apparatus according to the present disclosure, the moisture adsorption area in the second space is configured such that the shape of the air path through which the airflow flows converges, such that the pressure loss of the airflow can be effectively compensated under the condition that the moisture in the drying airflow is continuously adsorbed to reduce the density of the drying airflow, the pressure and flow rate of the airflow can remain stable, and the airflow can be fully in contact with the moisture adsorption-desorption member. Therefore, the moisture adsorption-desorption member can achieve a better adsorption effect on the drying airflow flowing therein.

[0056] In addition, by keeping the distance between the bottom plate of the second drying module housing 320 located in the regeneration area 3a of the second space and the corresponding surface of the moisture adsorption-desorption member 300 unchanged, the flow height of the drying airflow in the regeneration area 3a of the drying module remains unchanged, such that the heat received by each part of the moisture adsorption-desorption member rotating through the regeneration area 3a is uniform, achieving substantially the same regeneration effect, while avoiding the local overheating of the regeneration area 3a.

[0057] In addition, by further providing a flow dividing member on the bottom plate of the second drying module housing 320 in the moisture adsorption area in the flow direction of the drying airflow, the drying airflow flowing into the moisture adsorption area can be divided. One part enters the area proximal to the center of the circle, and another part enters the area proximal to the periphery of the moisture adsorption-desorption member, such that the drying airflow flowing into the airflow channel is more dispersed and uniform, and can be in contact with the moisture adsorption-desorption member more uniformly, thereby improving the moisture adsorption efficiency of the moisture adsorption-desorption member.

[0058] As shown in FIGs. 10 to 11, the clothing treatment apparatus according to the present disclosure further includes an upper cover plate structure 4. The upper cover plate structure 4 is disposed above the drying module 3 to cover the drying module device 3. The upper cover plate structure 4 includes a frame body 41 and a cover plate 42 surrounded by the frame body 41, and the cover plate 42 includes at least one thermal insulation layer 421.

[0059] In the clothing treatment apparatus according to the present disclosure, the drying module 3 is disposed above the drum 2, and the thermal insulation layer 421 is disposed in a washing machine housing panel above the drying module 3. This arrangement method can make full use of the upper space of the drum 2, making the overall arrangement of the clothing treatment device compact.

[0060] As shown in FIGs. 10 and 11, the cover plate 42 includes the thermal insulation layer 421, a protective layer 422 disposed above the thermal insulation layer 421, and an insulation layer 423 disposed below the thermal insulation layer 421. The frame body 41 includes an inner frame 411, an outer frame 412, and a connection surface 413 connecting the inner frame 411 and the outer frame 412. In some embodiments, a plurality of reinforcing ribs may be further disposed between the inner frame 411 and the outer frame 412.

[0061] It can be understood that the upper cover plate structure 4 may also be integrally formed by the cover plate 42 and fixing components around the cover plate 42. The cover plate 42 may also include only the thermal insulation layer 421, or may include the thermal insulation layer 421 and the protective layer 422 disposed above the thermal insulation layer 421, or may include the thermal insulation layer 421 and the insulation layer 423 disposed below the thermal insulation layer, or may include the thermal insulation layer 421, the protective layer 422 disposed above the thermal insulation layer 421, and the insulation layer 423 disposed below the thermal insulation layer 421.

[0062] As shown in FIGs. 1 to 14, the clothing treatment device further includes an air outlet duct 5. The air outlet duct 5 is connected to the drum air outlet 202 of the drum 2 at one end and connected to the first air inlet 33 at another end. A filter screen 50 may be disposed in the air outlet duct 5 to filter out impurities such as wool in the airflow, so as to prevent the impurities from entering the drying module 3 and causing problems such as clog of the drying module. The air outlet duct 5 is configured to guide a humid circulating airflow from the drum 2 to the first air inlet 33 of the drying module 3.

[0063] As shown in FIG. 14, in some embodiments, the filter screen 50 may be obliquely disposed in the air outlet duct 5. For example, the filter screen 50 may be detachably fixed in the air outlet duct 5 by a filter screen holder. The filter screen 50 optionally spans the entire cross section of the air outlet duct 5 such that at least a majority of the humid circulating airflow flowing out of the drum 2 passes through the filter screen 50 for filtering the airflow flowing through the air outlet duct.

[0064] In some embodiments, the filter screen 50 may be circular, elliptical, rectangular, or the like. In order to increase a filtration area of the filter screen 50, the filter screen 50 may be obliquely disposed in the air outlet duct 5, that is, there is a certain included angle between the normal line of the filter screen 50 and the extending direction of the air outlet duct 5. For example, the filtration area is S1, a cross-sectional area of the air outlet duct 5 is S2 in a section where the filter screen 50 exists in the air outlet duct 5, where S1:S2 is in the range of 5:1 to 1:1, such that the filtration area of the filter screen is maximized, thereby improving the filtering efficiency. S1:S2 is preferably approximately 3:1. For example, the filtration area of the filter screen 50 is 15,000 mm 2< , and the cross-sectional area of the air outlet duct 5 is 5000 mm 2< .

[0065] As shown in FIG. 13, the filter screen 50 has a porous structure, and may be made of metal, plastic, or other materials, which is not limited herein, as long as the filtering effect can be achieved. The definition of the pore size of filter screen is the same as the definition of the pore size of the moisture adsorption-desorption member 300, and details are not described herein again.

[0066] As shown in FIG. 14, the filter screen 50 includes a filtering surface 501 proximal to the drum air outlet 202 and a non-filtering surface 502 distal to the drum air outlet 202, and one or more reinforcing ribs 51 are disposed on one side of the filtering surface 501 and / or the non-filtering surface 502.

[0067] As shown in FIG. 14, the clothing treatment device further includes a filter screen cleaning device 52 capable of guiding a cleaning fluid to the filtering surface 501 and / or the non-filtering surface 502 of the filter screen 50 to clean the filter screen 50. By configuring the filter screen cleaning device 52 to automatically clean the filter screen 50 in the air outlet duct 5, impurities such as wool attached to the filter screen 50 can be removed, thereby reducing the possibility of the filter screen 50 being clogged, and ensuring the filtering efficiency of the filter screen during drying of the clothing treatment device. During the drying, since the hot and humid air is guided from the drum 2 to the air outlet duct 5 and then enters the first air inlet 33, the filter screen 50 in the air outlet duct 5 is deformed to a certain extent under an action force F of the airflow and tends to become loose. As shown in FIG. 14, the filter screen 50 is subjected to the upward action force F of the airflow. By disposing the reinforcing ribs 51 on one side of the filtering surface 501 and / or the non-filtering surface 502 of the filter screen 50, the filter screen remains taut during operation, and is not loosened due to an increase number of washings and the impact of the airflow, thereby extending the service life of the filter screen. At the same time, the wool 500 attached to the filter screen is more likely to fall off from the filter screen 50 under the flushing action of the cleaning fluid ejected from the cleaning apparatus, thereby achieving a better cleaning effect.

[0068] As shown in FIG. 15, a pore size of a moisture adsorption pore of the moisture adsorption-desorption member 300 is a wave height of the moisture adsorption-desorption member, or a pore size of a moisture adsorption pore of the moisture adsorption-desorption member 300 is a diameter of a circumscribed circle of the moisture adsorption pore of the moisture adsorption-desorption member 300.

[0069] In the present disclosure, the pore size of the moisture adsorption pore of the moisture adsorption-desorption member 300 and a pore size of a mesh pore of the filter screen are specifically set to improve the impact on the service life of the moisture adsorption-desorption member 300 and the clothing treatment device. For a specific solution, reference can be made to the following descriptions.

[0070] At room temperature of 25°C, the clothing treatment apparatus continuously washes and dries the pure cotton clothes in a conventional washing and drying mode. The clothing treatment apparatus runs continuously for 12 hours every day, and washes and dries 4 kg of clothes each time for about 3 hours. During the whole test process, the automatic cleaning function of the filter screen is activated, and other components such as a moisture adsorption rotary disk are not cleaned and maintained. After 30 days of operation, the moisture adsorption rotary disk member is disassembled and a clog rate thereof is measured. It should be noted that the clog rate is a proportion of the area of clogged moisture adsorption pores to the total moisture adsorption area. When the clog rate is greater than or equal to 25%, it is considered that the clog rate exceeds a stable operation threshold of the clothing treatment device, which in this case will greatly affect the drying efficiency. In other words, under normal use of the clothing treatment device, there is a risk that the moisture adsorption rotary disk member is clogged.

[0071] The service life of the clothing treatment apparatus is estimated assuming that the clothing treatment apparatus reliably operates 5000 times under the rated conditions and is used 3 times per week for about 9 hours. According to the provisions of "General Rules for Safe Service Life and Reuse of Household and Similar Electrical Appliances" issued by the Standardization Administration of China, the reference safe service life of a washing machine is 8 years.

[0072] In some embodiments, a molecular sieve-type dehumidification rotary disk can be selected as the moisture adsorption-desorption member 300, with a static water adsorption rate greater than 15% and a regeneration rate greater than 85% after moisture adsorption (processed at 250°C for 4 hours). It should be noted that a material selected for the moisture adsorption-desorption member 300 is not particularly limited, as long as the water adsorption rate and the regeneration rate of the material are within this range. The moisture adsorption rotary disk member may be provided with a rotary disk diameter of 327 mm and a thickness of 25 mm. Moisture adsorption pores are arranged in a regular corrugated shape, and have a wave height b and a wavelength 2b (the wavelength is approximately twice the wave height). Therefore, the wave height b can be used as the pore size of the moisture adsorption pore.

[0095] In summary, the clothing treatment apparatus according to the present disclosure optimizes structural parameters of the moisture adsorption rotary disk in the drying module, such as the size of the moisture adsorption pore and the size of the mesh pore of the filter screen in the filter assembly, to achieve optimal drying effect while ensuring the reliable operation of the system.

[0096] Referring to FIGs. 16 and 17, the drum 2 of the clothing treatment device according to the present disclosure includes an inner drum 2a, an outer drum 2b, and a drum driving part 2c. The drum driving part 2c is in transmission connection with the inner drum 2a of the drum 2 to drive the inner drum 2a of the drum 2 to rotate along the rotation shaft. At least one drum air inlet 203 and at least one drum air outlet 202 are formed at different positions on the outer drum 2b.

[0097] As shown in FIG. 12, the inner drum 2a of the drum 2 has a diameter D2, and the moisture adsorption-desorption member 300 is a disc-shaped member having a diameter D1. The diameter D1 of the moisture adsorption-desorption member 300 is less than the diameter D2 of the inner drum of the drum, and a ratio of D1:D2 ranges from 1:2 to 3:4. The ratio of D1:D2 is preferably 3:5.

[0098] The moisture adsorption-desorption member 300 has a thickness H, and a ratio of the thickness H to the diameter D1 ranges from 1:20 to 1:4. Preferably, the ratio of the thickness H to the diameter D1 ranges from 1:15 to 1:10.

[0099] By setting the size of the drum in the washing machine and the size of the rotary disk member to realize the drying function to be in a proportion relationship matching each other, the drying module can have a drying capacity corresponding to the drum, thereby improving the drying efficiency.
