[0002] The present disclosure is in the technical field of electrical appliances, and more particularly relates to laundry treatment equipment. [Background technology]

[0003] Driven by factors such as people's increasing pursuit of a healthier and higher quality of life and the accelerating pace of urban dwellers' lives, washer-dryers have emerged and are deeply loved by consumers. Washer-dryers are ideal for families in the south, especially during the rainy season, and in the north, where poor air quality makes it unsuitable for drying clothes outdoors, as well as for people who want to wear their clothes immediately after washing and want them to feel fuller and more comfortable.

[0004] Most conventional laundry treatment equipment with a drying function uses an evaporator to heat and absorb moisture from the moist air in the inner drum of a washer / dryer, obtaining high-temperature air that is then reintroduced into the inner drum of the washer / dryer to evaporate moisture from the clothes. However, the temperature of the entire evaporator remains the same, and as the moist air evaporates, the evaporator's moisture absorption capacity for the moist air decreases, reducing moisture absorption efficiency, resulting in longer drying times and higher power consumption. Some methods also use condensate sprays or condensers to directly dehumidify the moist airflow, but the resulting airflow still has a very high moisture content. Recycling the airflow requires "heating-cooling and dehumidification-reheating," resulting in relatively low dehumidification efficiency and relatively high power consumption.

[0005] Therefore, there is an urgent need to design a clothes treatment equipment that overcomes the above drawbacks, has reasonable power consumption, and has a better drying effect. Summary of the Invention

[0006] In order to overcome the above drawbacks, the present disclosure provides a clothes treatment device with a drying function that can reasonably reduce power consumption and achieve better drying effect.

[0007] The clothing processing equipment according to the present disclosure includes a drying module and a drum. The drum has at least one drum exhaust port and one drum inlet, and the drum exhaust port and the drum inlet are airflow-connected to the drying module, forming a dry 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 absorbing and desorbing member installed between the first drying module housing and the second drying module housing. The second space includes at least a dehumidifying region (3b) and a regenerating region (3a), and a first airflow inlet is provided in the dehumidifying region (3b). At least a portion of the moisture absorbing and desorbing member periodically passes through the dehumidifying region (3b) and the regenerating region (3a). A vertical distance is provided from a base plate of the second drying module housing to a corresponding surface of the moisture absorbing and desorbing member, and in the dehumidifying region (3b), the vertical distance near the first airflow inlet is different from at least a portion of the vertical distance at other positions away from the first airflow inlet.

[0008] In the clothing treatment equipment according to the present disclosure, the partial space formed by the second drying module housing and the moisture absorption and desorption member is spaced apart vertically from the base plate of the second drying module housing to the corresponding surface of the moisture absorption and desorption member, and in the dehumidifying region 3b, the distance near the first airflow inlet is different from at least a portion of the distance at other positions away from the first airflow inlet, so that the shape of the air circuit in the air flow direction converges, thereby effectively compensating for the pressure loss of the airflow, stabilizing the pressure and flow rate of the airflow, and ensuring sufficient contact with the moisture absorption and desorption member when moisture in the dry airflow is continuously adsorbed and the density of the dry airflow decreases. Therefore, the moisture absorption and desorption member can exert a better adsorption effect on the flowing dry airflow. [Brief explanation of the drawings]

[0030] As used herein, the term "regenerate" refers to at least partially dehumidifying an object that was originally relatively dry after absorbing moisture, thereby restoring it to a relatively dry state. The terms "upstream" and "downstream" are used to refer to the relative locations of a first element passed by an airflow and a second element thereafter in a flow path originating at an air inlet in the system, where the first element is "upstream" of the second element and the second element is "downstream" of the first element.

[0031] As shown in FIGS. 1 to 4, 14, and 17, the present disclosure provides a laundry treatment facility 1 including a drying module 3 and a drum 2. The drum 2 has at least one drum exhaust port 202 and a drum inlet 203. The drum exhaust port 202 and the drum inlet 203 are airflow-communicated with the drying module 3, respectively, to form a dry airflow path. The drying module 3 is installed above the drum 2 and includes a first exhaust port 32 and a first inlet 33. The drying module 3 is connected to the drum exhaust port 202 via the first inlet 33 and to the drum inlet 203 via the first exhaust port 32. In this way, the drying module 3 and the drum 2 form a circulation path, which dries the hot and humid air circulating therethrough.

[0032] In the drying mode, the dry airflow is directed from the drum 2 to the drying module 3 through the first air intake 33 of the drying module 3, which dehumidifies and heats the dry airflow from the drum 2, and then returns the dry airflow to the drum 2 through the first air exhaust 32 of the drying module 3, repeating this cycle to dry the clothes.

[0033] 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 absorbing and desorbing member 300. The moisture absorbing and desorbing member 300 can be made of a material with excellent moisture absorption and desorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The moisture absorbing and desorbing member 300 may be installed in various shapes, such as a circular rotating disk, a strip-shaped moisture absorbing belt, or a container with an opening of various shapes. Furthermore, when a rotating disk is selected as the moisture absorbing and desorbing member 300, the drying module 3 may further include a driving assembly, which may include a motor capable of driving the rotation of the rotating disk.

[0034] As will be understood, the pore size of the moisture absorbent and desorbent member 300 generally represents the diameter of the pore structure of the member, and when the pores are regular in shape, such as rectangular, triangular, circular, elliptical, or corrugated, the corresponding pore size will 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 hole, etc. In some embodiments, the pore size can be characterized by the wave height in the moisture absorbent and desorbent member, such as the wave height of the corrugated hole shape, or the pore size can also be characterized by the diameter of the circumscribed circle of the moisture absorbent hole in the moisture absorbent and desorbent member.

[0035] 6, the first dryer module housing 310 has a first space, the second dryer module housing 320 has a second space, and the moisture absorption and desorption member 300 is installed between the first dryer module housing 310 and the second dryer module housing 320. A gap is formed between a first surface 3001 of the moisture absorption and desorption member 300 and a part of the top wall of the first dryer module housing 310, forming a first airflow passage. A gap is formed between a second surface 3002 of the moisture absorption and desorption member 300 and a part of the base plate of the second dryer module housing 320, forming a second airflow passage. The second airflow passage, the moisture absorption and desorption member 300, and the first airflow passage form an airflow path. The second dryer module housing 320 includes a base plate 3201 of the second dryer module housing and a peripheral side wall protruding from the base plate, and the formed recess is the second space. Two second partition members 321 are installed along the radial direction of the second dryer module housing 320 in the second space to divide the second space into a dehumidifying region 3b and a regenerating region 3a. As the moisture absorbing and desorbing member 300 rotates, it circulates between the dehumidifying region 3b and the regenerating region 3a, continuously adsorbing and desorbing moisture. This allows the moisture absorbing and dehumidifying member 300 to maintain good moisture absorption capacity and improve the efficiency and effectiveness of moisture absorption. In some embodiments, the two second partition members 321 are arranged in a V-shape, and the dehumidifying region 3b and the regenerating region 3a are roughly fan-shaped.

[0036] 5, the first dryer module housing 310 includes a first dryer module housing top wall 3101 and a circumferential side wall, and the formed recess defines a first space. Two first partition members 311 are disposed along the radial direction of the first dryer module housing at positions corresponding to the two second partition members 321 in the first space to divide the first space into a dehumidifying region 3b and a regeneration module mounting region 3c. The recess structures of the first dryer module housing 310 and the second dryer module housing 320 are disposed relative to each other. When the first dryer module housing 310 and the second dryer module housing 320 are mated and connected, the first space and the second space can form an accommodation chamber for the moisture absorption and desorption member 300. Airflow passes through the accommodation chamber for the moisture absorption and desorption member 300, and the first dryer module housing 310 and the second dryer module housing 320 may be hermetically connected. To prevent the dry airflow discharged from the drum and the regeneration airflow from communicating with each other, the moisture absorption and desorption member 300 is positioned between the second partition member 311 and the first partition member 321. The second partition member 321 and the first partition member 311 form a dynamic sealing effect between the moisture absorption and desorption member 300. As the moisture absorption and desorption member 300 passes through the dehumidification region 3b and the regeneration region 3a during rotation, it continuously adsorbs and desorbs moisture. This allows the moisture absorption and dehumidification member 300 to maintain good moisture absorption capacity and improve the efficiency and effectiveness of moisture absorption. In some embodiments, the two first partition members 311 are arranged in a V-shape, and the dehumidification region 3b and the regeneration module mounting region 3c are roughly fan-shaped.

[0037] The partition member referred to here refers to each individual partition member that is radially connected and installed from the peripheral side wall to the center position of the housing of the first drying module housing 310 or the second drying module housing 320. The at least two first partition members 311 and the at least two second partition members 321 may be integrally formed or may be manufactured and attached separately, and the manufacturing method does not affect the definition of the partition member.

[0038] As shown in Figures 4 to 6, a first airflow inlet 301 is provided in the second space, and a first airflow outlet 304 is provided in the first space, and the dry airflow passes through the first airflow inlet 301, passes through the second space, the moisture absorbing and releasing member 300 and the first space in that order, and finally flows out from the first airflow outlet 304.

[0039] 7a is a cross-sectional schematic diagram of the dehumidifying region 3b when the drying module according to the present disclosure is installed horizontally. Note that this schematic diagram is a schematic illustration of the cross-sectional structure, and is intended merely to explain the structure of the dehumidifying region 3b and does not represent the actual shape. As shown in FIG. 7a, the second drying module housing 320 has a second space 3202. In the dehumidifying region 3b of the second space 3202, a distance d is provided in the vertical direction from the base plate 3201 of the second drying module housing to the second surface 3002 of the moisture absorption and desorption member. When viewed along the overall flow direction of the dry airflow in the second space 3202, the distance d near the first airflow inlet 301 in the second space 3202 is different from at least a portion of the distance d at other positions away from the first airflow inlet 301.

[0040] As should be understood, the "overall flow direction" of the dry airflow in the second space 3202 refers to the approximate flow direction of the dry airflow formed when the airflow flowing in the space between the second surface 3002 of the moisture absorption and desorption member and the base plate 3201 of the second dry module housing is viewed as a whole, that is, refers to the direction of flow generally from the first airflow inlet 301 to the first airflow outlet 304, as shown by the arrow in Fig. 6. Note that in the second space 3202, if the flow of a portion of the dry airflow differs from the overall flow direction, for example, if the dry airflow passes from the second space 3202 through the moisture absorption and desorption member 300 to reach the first space 3102, the "overall flow direction" will not be changed by that portion of the dry airflow.

[0041] This installation allows the shape of the air circuit through which the dry airflow flows to converge, thereby effectively compensating for the pressure loss of the airflow when moisture in the dry airflow is continuously adsorbed and the density of the dry airflow decreases.

[0042] In some embodiments, when viewed along the overall flow direction of the dry air flow in the second space 3202, in the dehumidification region 3b, the distance d at the first air flow inlet 301 is greater than the distance d at at least some points away from the first air flow inlet 301.

[0043] In some embodiments, when viewed along the overall flow direction of the dry air flow in the second space 3202, in the dehumidification area 3b, the distance d gradually decreases from the first air flow inlet 301 in a direction gradually moving away from the first air flow inlet 301.

[0044] In some embodiments, the second surface 3002 of the moisture absorption and desorption member is generally flat, and an angle ranging from 0° to 45° is formed between the plane on which the base plate 3201 of the second dry module housing is located and the plane on which the second surface 3002 of the moisture absorption and desorption member is located in the second space 3202. Preferably, an angle ranging from 5° to 15° is formed between the plane on which at least a portion of the base plate 3201 of the second dry module housing is located and the plane on which the second surface 3002 of the moisture absorption and desorption member is located.

[0045] In some embodiments, the distance is 15 to 50 mm near the first airflow inlet 301 of the second space 3202, and 8 to 40 mm at the point farthest from the first airflow inlet 301. The distance is preferably 20 to 40 mm at the first airflow inlet 301 of the second space 3202, and 10 to 26 mm at the point farthest from the first airflow inlet 301. The farthest point here refers to the end position of the moisture absorption region in the second space 3202, i.e., the boundary position between the moisture absorption region and the regeneration region 3a, along the overall flow direction of the dry airflow in the second space 3202.

[0046] According to the above embodiment, the shape of the air circuit through which the dry airflow flows can be converged, so that when moisture in the dry airflow is continuously adsorbed and the density of the dry airflow decreases, the pressure loss of the airflow can be effectively compensated, the pressure and flow rate of the airflow can be kept stable, and sufficient contact with the moisture absorption and desorption member 300 can be achieved.

[0047] The technical solution of the present disclosure allows the dry airflow to achieve a relatively uniform adsorption effect at each portion of the moisture absorbing and desorbing member 300 .

[0048] In addition, as shown in Figure 7b, the first drying module housing 310, the moisture absorption and desorption member 300, and the second drying module housing 5320 can also be installed vertically, and their structure and the drying principle achieved correspond one-to-one to the first drying module housing 310, the moisture absorption and desorption member 300, and the second drying module housing 320 installed horizontally in Figure 7a, so their description will be omitted here.

[0049] As shown in Figures 7a and 7b, the top wall 3101 of the first drying module housing and the base plate 3201 of the second drying module housing may extend at a gradual incline after being spaced a certain distance from the first airflow inlet 301, but in other embodiments, the top wall 3101 of the first drying module housing and / or the base plate 3201 of the second drying module housing may extend at a slant directly near the first airflow inlet 301.

[0050] 7a and 7b, both first dryer module housing 310 and second dryer module housing 320 have a base plate or top wall that extends at a gradual incline. However, in practice, only first dryer module housing 310 may have first dryer module housing top wall 3101 that extends at a gradual incline, or only second dryer module housing 320 may have second dryer module housing base plate 3201 that extends at a gradual incline.

[0051] As shown in FIG. 4 , the drying module further includes a regeneration module 31 that is mated with a first drying module housing 310 to form a generally fan-shaped regeneration module receiving section on the first drying module housing 310. The regeneration module 31 is attached to the regeneration module receiving section and positioned above the moisture absorption and desorption member 300. The regeneration module 31 is used, for example, to heat the regeneration airflow and desorb moisture adsorbed by the moisture absorption and desorption member 300. The regeneration module 31 may include a heating assembly for heating the regeneration airflow. The moisture absorption and desorption member 300 passes through the dehumidification region and the regeneration region during rotation, continuously performing a cycle of moisture adsorption and desorption. Preferably, the heating assembly may be an element with a heating function, such as a heating wire or a PTC heater.

[0052] In some embodiments, the area of ​​the dehumidifying region 3b in the second space 3202 is equal to or larger than the area of ​​the regenerating region 3a, and the ratio of the area of ​​the dehumidifying region 3b to the area of ​​the regenerating region 3a is approximately 5:1 to 1:1.

[0053] In some embodiments, a circulation fan 6 is further installed between the first air inlet 33 of the drying module and the drum outlet 202 to accelerate the flow rate of the circulating moisture-absorbing air. The rotation speed of the circulation fan 6 can be adjusted according to the drying process.

[0054] In some embodiments, the rotation speed of the circulation fan 6 can be adjusted depending on the air temperature at the first outlet 32 ​​of the drying module.

[0055] As shown in Figures 1 and 2, the drying module 3, the first air intake 33 and the first air exhaust 32 are all located at the top of the clothing treatment device. This arrangement allows full utilization of the space above the drum 2, making the overall arrangement of the clothing treatment device very compact.

[0056] As shown in FIG. 6 , the second dryer module housing 320 further includes a diverting member 322 disposed along the direction of the dry airflow in the moisture absorption region of the second space 3202. The diverting member 322 is configured to divide the dry airflow in the moisture absorption region. Specifically, one or more diverting members 322 can be installed. When two or more diverting members 322 are installed, they can be offset to divide the space into multiple diverting regions. By installing the diverting member 322 on the base plate 3201 of the second dryer module housing, the dry airflow flowing into the moisture absorption region of the second space 3202 can be diverted, with a portion flowing into a region adjacent to the center and another portion flowing into a region adjacent to the outer periphery of the moisture absorption and desorption member 300. This allows the dry airflow flowing into the circulation path to be more dispersed and uniform, allowing a wider area of ​​the airflow to contact the moisture absorption and desorption member 300, thereby improving the moisture absorption efficiency of the moisture absorption and desorption member 300.

[0057] In one embodiment shown in Figure 8a, the first drying module housing 320, the moisture absorption and desorption member 300, and the second drying module housing 310 are installed horizontally, and in the regeneration area 3a, there is a gap between the first surface 3001 of the moisture absorption and desorption member 300 and at least a part of the second drying module housing 310, forming a third space 3302, and there is a gap between the second surface 2002 of the moisture absorption and desorption member 300 and at least a part of the first drying module housing 320, forming a fourth space 3402.

[0058] In the regeneration zone 3a, the top wall 3101 of the first dryer module housing is parallel or approximately parallel to the first surface 3001 of the moisture absorption and desorption member along the airflow direction, and the base plate 3201 of the second dryer module housing is parallel or approximately parallel to the second surface 3002 of the moisture absorption and desorption member, so the heights of the third space 3302 and the fourth space 3402 do not change. By arranging the top wall 3101 of the first dryer module housing and the first surface 3001 of the moisture absorption and desorption member, both of which are located in the sectoral region of the regeneration zone 3a, and the base plate 3201 of the second dryer module housing and the second surface 3002 of the moisture absorption and desorption member in parallel, the height of the dry airflow does not change, so that the heat received by each part of the moisture absorption and desorption member 300 rotating through the regeneration zone 3a is uniform, achieving essentially the same regeneration effect while avoiding local overheating in the regeneration zone 3a.

[0059] In one embodiment shown in FIG. 8b, the first drying module housing 320, the moisture absorbing and releasing member 300, and the second drying module housing 310 can be installed vertically.

[0060] Similarly, due to this vertical installation, in the regeneration area 3a, the distances between the top wall 3101 of the first drying module housing, the base plate 3201 of the second drying module housing, and the corresponding surfaces of the moisture absorbing and desorbing members do not change.

[0061] Furthermore, as shown in FIG. 9, an inclined wall 3103 is installed radially at the position of the dehumidification area 3b of the first space close to the first airflow outlet 304, and this inclined wall 3103 smoothly and gradually moves away from the first surface 3001 of the moisture absorption and desorption member, so that the top wall 3101 of the first drying module housing is formed in an approximately stepped manner in the extension direction of the inclined wall 3103.

[0062] The second drying module housing 320 includes a base plate 3201 and a circumferential sidewall protruding from the base plate 3201, with the recessed portion defining the second space. Three second partition members 321 are installed in the second space, dividing the second space into a dehumidifying region 3b, a temperature-reducing region, and a regeneration region 3a. Correspondingly, the first drying module housing 310 includes a top wall 3101 and a circumferential sidewall of the first drying module housing, with the recessed portion defining the first space. Three first partition members 311 are installed along the radial direction of the first drying module housing 310 at positions of the three second partition members 321 corresponding to the first space 3102, dividing the first drying module housing 310 into a dehumidifying region 3b, a temperature-reducing region, and a regeneration module mounting region 3c. The recessed portions of the first and second dryer module housings 310 and 320 are arranged opposite each other, and the first and second dryer module housings 310 and 320 are hermetically sealed. During rotation, the moisture absorbing and desorbing member 300 absorbs moisture from the circulating airflow in the moisture absorption region, cools the moisture absorbing and desorbing member 300 in the temperature reduction region, and expels the moisture absorbed in the moisture absorption region via the moisture release stream in the regeneration region 3a. Preferably, the dehumidification region 3b, temperature reduction region, regeneration region 3a, and regeneration module mounting region 3c are generally fan-shaped. Similarly, in this embodiment, a regeneration module 31 is mounted in the regeneration module mounting region 3c. The structure and mounting method of the regeneration module 31 are the same as those described above, and therefore will not be described here.

[0063] In some embodiments, the area of ​​the dehumidification region 3b of the second space 3202 is greater than or equal to the area of ​​the temperature reduction region and the area of ​​the regeneration region 3a, and the ratio of the area of ​​the dehumidification region 3b to the area of ​​the temperature reduction region and the area of ​​the regeneration region 3a is approximately 4:1:1 to 1:1:1.

[0064] In other embodiments, the structure of the laundry treatment facility 1 is basically the same as that of the first embodiment, so the description thereof will be omitted here.

[0065] In some other embodiments, the second space 3202 has a first air flow inlet 301, and the dry air flow passes through the first air flow inlet 301 and passes through the second space 3202, the moisture absorption and desorption member 300 and the first space 3102 in sequence, and when viewed along the overall flow direction of the dry air flow in the second space 3202, the moisture absorption region has a cross-sectional area different from that of the first air flow inlet 301 at at least some positions away from the first air flow inlet 301.

[0066] As will be understood, the "overall flow direction" of the dry airflow in second space 3202 refers to the general flow direction of the formed dry airflow when viewing the airflow flowing as a whole in the space between second surface 3002 of the moisture absorption and desorption member and base plate 3201 of the second dry module housing, as shown by the arrow in Fig. 6, i.e., the general direction of flow from first airflow inlet 301 to first airflow outlet 304. Note that in second space 3202, if the flow of a portion of the dry airflow differs from the general flow direction, for example, if the dry airflow passes from second space 3202 through moisture absorption and desorption member 300 to reach first space 3102, the "overall flow direction" will not be changed by that portion of the dry airflow.

[0067] This installation allows the shape of the air circuit through which the dry airflow flows to converge, thereby effectively compensating for the pressure loss of the airflow when moisture in the dry airflow is continuously adsorbed and the density of the dry airflow decreases.

[0068] In some embodiments, when viewed along the overall flow direction of the dry airflow in the second space 3202, in the moisture-absorbing region, the cross-sectional area at the first airflow inlet 301 is larger than the cross-sectional area at at least some points away from the first airflow inlet 301.

[0069] In some embodiments, when viewed along the overall flow direction of the dry airflow in the second space, the cross-sectional area in the moisture-absorbing region gradually decreases from the first airflow inlet 301 in a direction gradually moving away from the first airflow inlet 301.

[0070] In some embodiments, when viewed from the overall flow direction of the dry air flow in the second space 3202, in the dehumidification area 3b, at least a portion of the base plate 3201 of the second drying module housing extends at a gradual upward incline, and the cross section of the second space 3202 along the radial direction of the moisture absorption and desorption member 300 is approximately a right-angled trapezoid.

[0071] As will be understood, the term "cross section" herein refers to a vertical cross section of the space formed between the base plate 3201, side walls, and corresponding surfaces of the moisture absorbing and releasing member 300 of the second drying module housing when viewed along the overall flow direction of the dry air flow in the second space 3202.

[0072] According to the above embodiment, the shape of the air circuit through which the dry airflow flows can be converged, so that when moisture in the dry airflow is continuously adsorbed and the density of the dry airflow decreases, the pressure loss of the airflow can be effectively compensated, the pressure and flow rate of the airflow can be kept stable, and sufficient contact with the moisture absorption and desorption member 300 can be achieved.

[0073] The technical solution of the present disclosure allows the dry airflow to achieve a relatively uniform adsorption effect at each portion of the moisture absorbing and desorbing member 300 .

[0074] In summary, the clothing treatment equipment according to the present disclosure has a moisture absorption area located in the second space that is positioned so as to converge the shape of the airflow path through which the gas flows. This effectively compensates for the pressure loss of the airflow when moisture in the dry airflow is continuously absorbed and the density of the dry airflow decreases, maintaining stable airflow pressure and flow rate, and ensuring sufficient contact with the moisture absorption and desorption member. This allows the moisture absorption and desorption member to exert a more effective adsorption effect on the dry airflow that flows through it.

[0075] Furthermore, since the distance between the base 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 absorption and desorption member 300 does not change, the flow height of the dry airflow in the regeneration area 3a of the drying module does not change, so the heat received by each part of the moisture absorption and desorption member rotating through the regeneration area 3a is uniform, thereby achieving basically the same regeneration effect and at the same time avoiding local overheating in the regeneration area 3a.

[0076] In addition, by installing a diverting member on the base plate of the second drying module housing 320 along the flow direction of the dry airflow in the moisture absorption area, the dry airflow flowing into the moisture absorption area can be diverted, with a portion flowing into an area close to the center of the circle and another portion flowing into an area close to the outer periphery of the moisture absorption and desorption member.This allows the dry airflow flowing into the airflow passage to become more dispersed and more uniform, and to come into more uniform contact with the moisture absorption and desorption member, thereby improving the moisture absorption efficiency of the moisture absorption and desorption member.

[0077] As shown in Figures 10 and 11, the clothing processing equipment according to the present disclosure also includes an upper cover structure 4 device installed above the drying module 3 and covering the drying module 3, the upper cover plate structure 4 including a frame 41 and a cover plate 42 surrounded by the frame 41, and the cover plate 42 including at least one insulating layer 421.

[0078] The clothing treatment equipment provided by the present invention installs the drying module 3 above the drum 2, and installs an insulating layer 421 on the washing machine housing panel above the drying module 3. This installation method can fully utilize the space above the drum 2, making the overall layout of the clothing treatment equipment very compact.

[0079] 10 and 11, the cover plate 42 includes a heat insulating layer 421, a protective layer 422 disposed above the heat insulating layer 421, and an insulating layer 423 disposed below the heat insulating layer 421. The frame 41 includes an inner frame 411, an outer frame 412, and a connecting 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.

[0080] As can be understood, the upper cover plate structure 4 can also be integrally formed by the cover plate 42 and a fixing member around the cover plate 42. The cover plate 42 may include only the heat insulating layer 421, or may include the heat insulating layer 421 and a protective layer 422 disposed above the heat insulating layer 421, or may include the heat insulating layer 421 and an insulating layer 423 disposed below the heat insulating layer 421, or may further include the heat insulating layer 421, the protective layer 422 disposed above the heat insulating layer 421, and the insulating layer 423 disposed below the heat insulating layer 421.

[0081] As shown in FIGS. 1 to 14, the laundry processing device further includes an exhaust duct 5, one end of which is connected to the drum exhaust port 202 of the drum 2 and the other end of which is connected to the first air intake port 33. A filter mesh 50 is installed inside the exhaust duct 5 to filter out impurities such as lint in the airflow, preventing the impurities from entering the drying module 3 and causing problems such as clogging of the drying module. The exhaust duct 5 is configured to guide the wet circulating airflow from the drum 2 to the first air intake port 33 of the drying module 3.

[0082] 14, in some embodiments, the filter mesh 50 may be installed at an angle within the exhaust duct 5. For example, the filter mesh 50 may be removably fixed to the exhaust duct 5 via a filter mesh bracket. The filter mesh 50 may be selectively arranged across the entire cross section of the exhaust duct 5, thereby allowing at least a majority of the humid circulating airflow exiting the drum 2 to pass through the filter mesh 50 and filtering the airflow flowing through the exhaust duct.

[0083] In some embodiments, the filter mesh 50 may be circular, elliptical, rectangular, or other shapes. To increase the filtering area of ​​the filter mesh 50, the filter mesh 50 may be installed at an angle within the exhaust duct 5, i.e., there is a certain angle between the normal to the filter mesh 50 and the extension direction of the exhaust duct 5. For example, the filtering area is S1, and the cross-sectional area of ​​the section of the exhaust duct 5 where the filter mesh 50 is located is S2. When the ratio S1:S2 is within the range of 5:1 to 1:1, the filtering area of ​​the filter mesh is maximized and filtering efficiency is improved. The ratio S1:S2 is preferably approximately 3:1. For example, the filtering area of ​​the filter mesh 50 is 15,000 mm 2 The cross-sectional area of ​​the exhaust duct 5 is 5000 mm 2 is.

[0084] 13, the filter mesh 50 has a porous structure, and its material may be metal, plastic, or other material, with no limitations imposed here, as long as it can achieve a filtering effect. The definition of the pore size of the filter mesh is the same as that of the moisture absorbing and desorbing member 300, and therefore a detailed explanation thereof will be omitted here.

[0085] As shown in FIG. 14, the filter mesh 50 includes a filtering surface 501 adjacent to the drum exhaust port 202 and a non-filtering surface 502 away from the drum intake port 202, and one or more reinforcing ribs 51 are provided on one side of the filtering surface 501 and / or the non-filtering surface 502.

[0086] As shown in FIG. 14, the laundry treatment device further includes a filter mesh cleaning device 52 that directs the washing liquid onto the filtering surface 501 and / or non-filtering surface 502 of the filter mesh 50 to clean the filter mesh 50. The filter mesh cleaning device 52 automatically cleans the filter mesh 50 in the exhaust duct 5, removing impurities such as lint from the filter mesh 50, reducing the possibility of clogging and ensuring the filtering efficiency of the filter mesh during the drying process of the laundry treatment device. During the drying process, hot and humid air is directed from the drum 2 into the exhaust duct 5 and then enters the first air inlet 33. The filter mesh 50 in the exhaust duct 5 is subjected to the airflow force F, which causes it to undergo a certain deformation and tends to loosen. As shown in FIG. 14, the filter mesh 50 is subjected to the upward airflow force F. By providing reinforcing ribs 51 on one side of the filtering surface 501 and / or non-filtering surface 502 of the filter mesh 50, the filter mesh is kept tight during operation and is not loosened by increased flushing frequency or airflow impact, thereby extending the service life of the filter mesh. At the same time, the lint 500 adsorbed on the filter mesh can be more easily removed from the filter mesh 50 by the cleaning action of the cleaning liquid sprayed from the cleaning device, achieving a better cleaning effect.

[0087] As shown in FIG. 15, the pore diameter of the moisture absorption pores of the moisture absorption and desorption member 300 is the wave height of the moisture absorption and desorption member, or the pore diameter of the moisture absorption pores of the moisture absorption and desorption member 300 is the diameter of the circumscribed circle of the moisture absorption pores of the moisture absorption and desorption member 300.

[0088] The present disclosure improves the service life of the moisture absorbing and releasing member 300 and the clothing treatment device by specifically setting the pore size of the moisture absorbing holes of the moisture absorbing and releasing member 300 and the pore size of the mesh of the filter mesh.

[0089] At a room temperature of 25°C, the laundry treatment equipment continuously washed and dried pure cotton clothes in the conventional washing and drying mode. Operating continuously for 12 hours per day, washing and drying 4 kg of clothes per cycle took approximately 3 hours. During the overall testing process, the automatic cleaning function of the filter mesh was activated, and other components, such as the moisture absorption turntable, were not cleaned or maintained. After 30 days of operation, the moisture absorption turntable components were disassembled and their clogging rate was measured. The clogging rate is defined as the percentage of clogged moisture absorption hole area relative to the total moisture absorption area. A clogging rate of 25% or higher is considered to have exceeded the stable operation threshold of the laundry treatment equipment, significantly affecting drying efficiency. This means that there is a risk of the moisture absorption turntable components becoming clogged during normal use of the laundry treatment equipment.

[0090] Assuming that the laundry treatment equipment operates reliably 5,000 times under rated conditions, 3 times a week for approximately 9 hours, its operating life is estimated. According to the "General Rules for the Safe Use Life and Recycling of Household and Similar Electrical Appliances" issued by the National Standardization Administration of China, the reference period for the safe use of washing machine products is 8 years.

[0091] In some embodiments, a molecular sieve dehumidifying turntable can be selected as the moisture absorption / desorption member 300, with a static water absorption rate of more than 15% and a regeneration rate after moisture absorption of more than 85% (treated at 250°C for 4 hours). The material selected for the moisture absorption / desorption member 300 is not particularly limited as long as the water absorption rate and regeneration rate of the material are within the above ranges. The moisture absorption turntable member can be installed with a turntable diameter of 327 mm and a thickness of 25 mm. The moisture absorption holes have a wave height b and a wavelength 2b (the wavelength is approximately twice the wave height) and are arranged in a generally regular wave pattern. Therefore, the wave height b can be used as the hole diameter of the moisture absorption holes.

[0114] In summary, the present disclosure provides a clothing processing equipment that achieves optimal drying effect by optimizing and designing the structural parameters of the moisture absorption turntable in the drying module, such as the size of the moisture absorption holes and the mesh hole size of the filter mesh in the filter mesh assembly, on the premise of ensuring reliable operation of the system.

At least one drum inlet 203 and at least one drum outlet 202 are formed at different positions on the outer drum 2b.

[0116] As shown in FIG. 12, the inner drum 2a of the drum 2 has a diameter D2, and the moisture absorbing and desorbing member 300 is a disk-shaped member having a diameter D1. The diameter D1 of the moisture absorbing and desorbing member 300 is smaller than the diameter D2 of the inner drum, and the ratio of D1:D2 is in the range of 1:2 to 3:4.
