[0070] In an embodiment of the present disclosure, as Figure 1 shown, the laundry treatment device includes a drying module 10 and a laundry treatment drum 20. An air inlet and an air outlet are provided on the laundry treatment drum 20. The air outlet of the drying module 10 is communicated with the air inlet of the laundry treatment drum 20, and the air inlet of the drying module 10 is communicated with the air outlet of the laundry treatment drum 20, so as to continuously dehydrate the gas in the laundry treatment drum 20 through the drying module 10, thereby achieving the purpose of drying the laundry in the laundry treatment drum 20.

[0071] As Figure 2 shown, the drying module 10 includes a heating module 100 and a dehumidification module 200. The air outlet of the dehumidification module 200 is communicated with the air inlet of the laundry treatment drum 20, and the air inlet of the dehumidification module 200 is communicated with the air outlet of the laundry treatment drum 20, so as to continuously adsorb the moisture in the gas in the laundry treatment drum 20 through the dehumidification module 200; the heating module 100 can heat the air flow and / or the moisture absorption and discharge member 230. The heated air flow passes through the moisture absorption and discharge member in the dehumidification module 200 to dehumidify and dehydrate the moisture absorption and discharge member, so that the moisture absorption and discharge member can again have the ability to adsorb moisture; during the rotation of the moisture absorption and discharge member, it passes through the dehumidification area of the dehumidification module 200 and the dehydration area of the heating module 100, and continuously performs a cycle process of adsorbing moisture and desorbing moisture, thereby achieving the purpose of drying the moisture of the laundry in the laundry treatment drum 20. Among them, the moisture absorption and discharge member can be a turntable, which is convenient for rotating through the dehumidification area of the dehumidification module 200 and the dehydration area of the heating module 100.

[0072] In one embodiment, as Figures 3 - 6As shown, the heating module 100 includes: a heating housing 110, a heater 140, and a first seal 130. The heating housing 110 forms a receiving space. An air inlet 111 and an air outlet 112 communicating with the receiving space are provided on the heating housing 110. A groove 120 surrounding the air outlet 112 is formed on the heating housing 110. The heater 140 is disposed in the receiving space and is configured to heat the gas in the receiving space. The first seal 130 is disposed in the groove 120.

[0073] For the heating module 100 provided by the present disclosure, the heater 140 can heat the gas in the receiving space to provide heated gas at a preset temperature through the heating module 100. When the heating module 100 supplies heated gas to the dehumidification module 200, for example, the air outlet 112 of the heating module 100 and the hot air inlet of the dehumidification module 200 need to be sealed and connected to ensure the temperature of the heated gas and prevent air leakage. A groove 120 surrounding the air outlet 112 is formed on the heating housing 110 of the present disclosure, and a first seal 130 is provided in the groove 120. When the heating housing 110 is sealed and connected to the dehumidification housing of the dehumidification module 200, the sealing structure on the dehumidification housing can extend into the groove 120 and abut against the first seal 130 to form a sealed connection. In addition, through the setting of the groove 120, on the one hand, the installation of the first seal 130 is formed, so that the first seal 130 can deform in the groove 120 when being squeezed, avoiding misalignment of the first seal 130 and resulting in sealing failure. On the other hand, the docking positioning during the sealed connection between the heating housing 110 and the dehumidification housing of the dehumidification module 200 is formed through the groove 120, which can further improve the sealing effect and reduce the assembly steps.

[0074] As Figure 4 shown, the opening direction of the groove 120 is the same as the direction of the air outlet 112. By making the opening direction of the groove 120 the same as the direction of the air outlet 112, when the air outlet 112 is connected to the hot air inlet of the dehumidification module 200, the sealing structure of the dehumidification housing can directly extend into the groove 120 along the connection direction, thereby pressing the first seal 130 in the groove 120 in the docking direction and further improving the sealing effect.

[0075] As Figure 5 and Figure 6 shown, the groove 120 is an annular groove surrounding the air outlet 112, and the first seal 130 is a sealing ring located in the annular groove. By setting the groove 120 as an annular shape, an annular groove can be formed in a circle around the circumference of the air outlet 112. Cooperating with using a sealing ring as the first seal 130, a sealing effect can be formed in a circle around the circumference of the air outlet 112 to avoid air leakage and further improve the sealing effect.

[0076] Among them, the first seal 130 can be a foamed silicone part. Foamed silicone can be used for a long time in the temperature range of -65°C to 200°C and maintain its soft elastic properties, so it will not be affected by the medium and high temperature gas generated by the heating module 100; at the same time, foamed silicone is water-resistant, aging-resistant, non-corrosive, and has a low linear shrinkage rate, and will not be affected by the humid environment of the clothing treatment equipment, and has stable life and elastic properties; in addition, foamed silicone is an environmentally friendly material, non-toxic and odorless, safe and hygienic; in the current market environment where users highly concern about hygiene and safety issues, using environmentally friendly materials can greatly enhance the competitiveness of the product in the market.

[0077] Of course, the first seal 130 can also be a rubber part, such as a rubber ring; or, the first seal 130 can also be a soft corrosion-resistant metal, such as an aluminum washer or a copper washer; or, the first seal 130 can also be a plastic part, such as PA6 (nylon 66), PEEK (polyether ether ketone), PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene resin), PC (polycarbonate) or PP (polypropylene), etc., and the present disclosure does not limit this.

[0078] Among them, in the depth direction of the groove 120, the depth of the groove 120 is greater than the height of the first seal 130. By making the depth of the groove 120 greater than the height of the first seal 130, the first seal 130 can be completely accommodated by the groove 120, which can improve the stability of the first seal 130 in the groove 120 and facilitate the assembly of the first seal 130 in the groove 120; in addition, when the groove 120 cooperates with the sealing structure of the dehumidification housing, the part of the groove 120 that protrudes above the first seal 130 can form a guide for the sealing structure extending into the groove 120.

[0079] Among them, the depth of the groove 120 can also be equal to the height of the first seal 130. By making the depth of the groove 120 equal to the height of the first seal 130, when the first seal 130 is assembled in the groove 120, the position of the first seal 130 at the opening of the groove 120 can be observed to judge whether the first seal 130 is installed flat and in place, which is convenient for the assembly of the first seal 130. Of course, the depth of the groove 120 can also be less than the height of the first seal 130, and the present disclosure does not limit this.

[0080] Specifically, in the width direction of the groove 120, the width of the groove 120 is less than or equal to the width of the first seal 130. By making the width of the groove 120 less than the width of the first seal 130, when the first seal 130 is assembled in the groove 120, a pre-tightening force on the first seal 130 can be formed by the side walls of the groove 120, so that the first seal 130 is pre-fixed in the groove 120, thereby avoiding the displacement of the first seal 130 after being assembled in the groove 120, and improving the sealing effect provided by the first seal 130.

[0081] Among them, in the width direction of the groove 120, the width of the groove 120 may also be equal to the width of the first seal 130. By making the width of the groove 120 equal to the width of the first seal 130, when the first seal 130 is assembled in the groove 120, the left and right gaps of the first seal 130 in the groove 120 can be observed to judge whether the first seal 130 is installed flat and in place, which is convenient for the assembly of the first seal 130. Of course, the width of the groove 120 may also be greater than the width of the first seal 130 to reserve a deformation accommodation space for the first seal 130 after being squeezed and deformed. The present disclosure does not limit this.

[0082] Among them, in the direction from the opening of the groove 120 towards the bottom of the groove, the width of the groove 120 decreases, that is, the cross-section of the groove 120 is trapezoidal. When the first seal 130 is assembled in the groove 120, the groove 120 with a larger opening is convenient for placing the first seal 130. Through the groove 120 with a decreasing width towards the bottom of the groove, the first seal 130 can be tightly fixed in the first groove 120; at the same time, when the first seal 130 is subjected to an external force extrusion, it can deform towards the bottom of the groove, further improving the sealing effect in the groove 120. Of course, in the direction from the opening of the groove 120 towards the bottom of the groove, the width of the groove 120 may also be the same or increasing. The present disclosure does not limit this.

[0083] As Figure 6 shown, in the depth direction of the groove 120, the height of the side wall of the groove 120 on the side close to the heater 140 is higher than the height of the side wall on the side far from the heater 140, that is, the height of the side wall of the groove 120 on the side close to the outside of the heating housing 110 is relatively small among the two opposite side walls of the groove 120. By making the height of the side wall of the groove 120 on the side close to the outside of the heating housing 110 relatively small among the two opposite side walls of the groove 120, when the groove 120 is matched with the sealing structure of the dehumidification housing, the relatively higher inner side wall of the groove 120 can form a lateral positioning for the sealing structure, improving the assembly efficiency; at the same time, through the relatively higher inner side wall of the groove 120, the hot air can be better blocked, further avoiding the occurrence of air leakage.

[0084] Wherein, when the groove 120 has different heights relative to the two side walls, the depth of the groove 120 is the height of the lower side wall.

[0085] As Figure 6 shown in the figure, the heating housing 110 includes a main body portion 1110, a side wall portion 1120, and an extension portion 1130. The side wall portion 1120 and the main body portion 1110 enclose a receiving space. The extension portion 1130 is located on the periphery of the side wall portion 1120, and the extension portion 1130 and the side wall portion 1120 enclose a groove 120. By providing the extension portion 1130 and the side wall portion 1120 to enclose the groove 120, the original structure of the side wall portion 1120 is retained, that is, the thickness of the side wall portion 1120 can maintain the original thickness. At the same time, the original structure of the side wall portion 1120 is retained, so that the receiving space formed by the side wall portion 1120 and the main body portion 1110 can maintain the original morphology, avoiding affecting the flow of gas in the receiving space.

[0086] Wherein, the wall thickness of the extension portion 1130 is greater than the wall thickness of the side wall portion 1120. Since the extension portion 1130 forms the groove 120 by connecting the extension portion 1130 to the side wall portion 1120, by setting the thickness of the extension portion 1130 to be larger, when assembling the heating housing 110, the extension portion 1130 can have greater structural strength, avoiding deformation of the groove 120 and resulting in a reduction or even failure of the sealing effect.

[0087] Wherein, the wall thickness of the extension portion 1130 is a, and the wall thickness of the side wall portion 1120 is b, 1 < a:b < 3. Of course, the wall thickness of the extension portion 1130 can be equal to or less than the wall thickness of the side wall portion 1120, and the present disclosure does not limit this.

[0088] As Figure 3 described, the air inlet 111 is provided on the side wall portion 1120. The main body portion 1110 and the side wall portion 1120 enclose a receiving space with an open end, and the open end serves as the air outlet 112.

[0089] Specifically, the heater 140 can be an electric heater. As Figure 4 described, the electric heater includes an electric heating tube, and the electric heating tube is coiled in the receiving space to heat the air flow passing through the receiving space through heat exchange. The electric heating tube can be controlled by a thermostat 150 to output heat, so as to realize the temperature control of the air flow heating. By using the electric heater in cooperation with the thermostat 150, precise control of the air flow temperature can be achieved.

[0090] As Figure 3As shown, the heating housing 110 includes a top wall and a side wall. The top wall and the side wall enclose to form a receiving space, and the thermostat 150 is disposed on the side wall. By disposing the thermostat 150 on the side wall of the heating housing 110, the thermostat 150 is closer to the actual temperature of the heating tube, and the temperature control is more accurate. In addition, when the heating housing 110 is made of an aluminum structure, through injection molding, it is beneficial to form an installation structure for installing the thermostat 150.

[0091] Wherein, a blind hole with an opening facing the periphery can be formed on the side wall as the installation structure, and the thermostat 150 is assembled in the blind hole. By forming a blind hole on the side wall to assemble the thermostat 150, it is possible to avoid stacking a seal at the position where the thermostat 150 is installed. Of course, the thermostat 150 can also be installed by forming a through hole on the side wall, and the present disclosure does not limit this.

[0092] As Figures 3 - 6 shown, the heating housing 110 of the heating module 100 is generally fan-shaped, that is, along the radial direction of the fan, the arc length of the heating module 100 closer to the rotation center of the moisture absorption and drainage member is smaller than the arc length away from the rotation center of the moisture absorption and drainage member.

[0093] Wherein, the main body portion 1110 of the heating housing 110 located on the top surface is fan-shaped; the side wall portion 1120 surrounds the main body portion 1110, and an air inlet 111 of the heating module 100 is formed on the side wall portion 1120 located on the outer arc surface of the fan. The gas to be heated is sent into the heating housing 110 through the air inlet 111. After the gas is heated by the heater 140 in the heating housing 110, it then flows through the air outlet 112 through the moisture absorption and drainage member, taking away the moisture in the moisture absorption and drainage member, and realizing the desorption of the moisture in the moisture absorption and drainage member.

[0094] By making the heating housing 110 of the heating module 100 fan-shaped, when the heating module 100 cooperates with the dehumidification module 200, facing the circular moisture absorption and drainage member, the heating module 100 and the dehumidification module 200 can cover the surface of the moisture absorption and drainage member as much as possible, so that as many parts or even all parts of the moisture absorption and drainage member are respectively located in the dehumidification area formed by the dehumidification module 200 and the dehydration area formed by the heating module 100, thereby relatively improving the drying ability of the clothes in the clothes treatment cylinder 20.

[0095] Wherein, the heating housing 110 of the heating module 100 is fan-shaped, and an air inlet 111 of the heating module 100 is formed on the side wall portion 1120 located on the outer arc surface of the fan. The direction in which the gas to be heated enters the accommodation cavity is different from the rotation direction of the moisture absorption and drainage member, which can make the heating gas have a higher flow rate relative to the moisture absorption and drainage member, thereby improving the desorption effect of the heating gas on the moisture in the moisture absorption and drainage member.

[0096] Wherein, as Figure 4As shown, the heater 140 can be composed of multiple heating tubes connected end to end. The heating tubes are distributed at intervals along the radial direction of the sector. The length of the heating tubes is arranged substantially perpendicular to the radius direction of the sector. After being connected, the multiple heating tubes are distributed in an S shape. The length of the heating tubes in the accommodating area is relatively longer, which can increase the contact area with the gas to be heated, so that the heat exchange efficiency with the gas to be heated is relatively higher.

[0097] As Figure 4 shown, the heating module 100 further includes: a wind guide plate 160. The wind guide plate 160 is arranged between the heater 140 and the main body part 1110, and the wind guide plate 160 is arranged at an interval from the main body part 1110. An air flow channel is formed between the wind guide plate 160 and the main body part 1110. This air flow hole communicates with the air inlet 111 of the heating module 100. After the gas to be heated enters the air flow channel formed between the wind guide plate 160 and the main body part 1110, it flows through the multiple heating tubes in the heater 140 under the guiding action of the wind guide plate 160; multiple ventilation holes are provided on the wind guide plate 160, and at least part of the ventilation holes are arranged opposite to the heating tubes. Through the wind guide plate 160, the gas to be heated can enter the heater 140 more evenly for heating.

[0098] Among them, multiple air holes can be arranged in rows along the radial direction of the sector. The setting position of each row of air holes corresponds approximately to the position of the heating tubes. The diameter of the air holes gradually increases from the outer arc to the center of the circle along the radial direction of the sector. The air inlet 111 of the heating module 100 is located on the outer arc side surface of the heating housing 110. The diameter of the air holes near the air inlet 111 is relatively smaller, and the diameter of the air holes far from the air inlet 111 is relatively larger, that is, the diameter of the air holes on the side close to the air inlet 111 is smaller than the diameter of the air holes on the side far from the air inlet 111, so as to ensure that the gas flow rate of each air hole is approximately the same, and the gas to be heated can enter the heater 140 more evenly for heating, improving the heating efficiency.

[0099] In one embodiment, as Figure 2 shown, the drying module 10 includes: a dehumidification module 200 and a heating module 100. As Figure 17 shown, the dehumidification module 200 includes a moisture absorption and drainage member 230 and a dehumidification housing. The dehumidification housing forms an accommodating space. An air inlet and an air outlet communicating with the accommodating space are provided on the dehumidification housing. The air outlet of the dehumidification housing communicates with the air inlet of the laundry treatment cylinder 20, and the air inlet of the dehumidification housing communicates with the air outlet of the laundry treatment cylinder 20. At least part of the moisture absorption and drainage member 230 is arranged in the accommodating space; as Figure 7As shown, a hot air inlet 212 is provided on the first dehumidification housing 210, and the moisture absorption and drainage member 230 is configured to be able to adsorb moisture in the gas entering the accommodation space; the heating module 100 is fixed on the first dehumidification housing 210, and at least part of the moisture absorption and drainage member 230 is disposed opposite to the air outlet 112 on the heating module 100, and the heating module 100 is configured to dehydrate the part of the moisture absorption and drainage member 230 located at the air outlet 112.

[0100] As Figure 7 shown, a connecting portion 211 is provided on the first dehumidification housing 210, a hot air inlet 212 is formed on the connecting portion 211, and the heating module 100 is assembled on the connecting portion 211 so that the air outlet 112 communicates with the hot air inlet 212; a convex portion 213 surrounding the hot air inlet 212 is formed on the connecting portion 211, and the convex portion 213 is correspondingly arranged with the groove 120. In the installed state, at least part of the convex portion 213 is located in the groove 120. When the heating housing 110 is hermetically connected to the first dehumidification housing 210 of the dehumidification module 200, the convex portion 213 on the first dehumidification housing 210 can extend into the groove 120 and abut against the first sealing member 130, thereby forming a sealed connection; in addition, the cooperation between the groove 120 and the convex portion 213 forms a docking positioning when the heating housing 110 and the first dehumidification housing 210 are hermetically connected, so that the sealing effect can be further improved and the assembly steps can be reduced.

[0101] Wherein, in the depth direction of the groove 120, the distance between the convex portion 213 and the bottom of the groove 120 is smaller than the thickness of the first sealing member 130 in the free state. By making the distance between the convex portion 213 and the bottom of the groove 120 smaller than the thickness of the first sealing member 130 in the free state, when the convex portion 213 is located in the groove 120, the first sealing member 130 in the groove 120 can be extruded, so that the first sealing member 130 is deformed to improve the sealing effect.

[0102] Wherein, when the groove 120 is annular around the air outlet 112, the convex portion 213 also correspondingly forms an annular protrusion around the hot air inlet 212, and the annular protrusion is located in the annular groove to achieve circumferential sealing with the annular sealing ring, avoiding air leakage and improving the sealing effect.

[0103] In one embodiment, as Figures 8 - 13As shown, the drying module 10 further includes: a regeneration module 300 and a second seal 170. The regeneration module 300 includes a regeneration housing 310 and a regeneration fan 320. The regeneration housing 310 forms a duct having a duct inlet 311 and a duct outlet 312. The regeneration fan 320 is disposed at the duct inlet 311 for inputting gas into the duct. The duct outlet 312 is connected to the air inlet 111. The second seal 170 is disposed between the duct outlet 312 and the air inlet 111, and the second seal 170 is configured to seal the connection gap between the duct outlet 312 and the air inlet 111.

[0104] As Figures 13 - 15 shown, the second seal 170 includes: a first seal portion 1710 and a second seal portion 1720. The first seal portion 1710 is disposed between the regeneration housing 310 and the heating housing 110 along the thickness direction Z of the regeneration housing 310. The second seal portion 1720 is disposed between the regeneration housing 310 and the heating housing 110 along the direction from the duct outlet 312 towards the air inlet 111 (the length direction X of the regeneration housing 310).

[0105] When the duct inlet 311 of the regeneration housing 310 is connected to the air inlet 111 of the heating housing 110, a stepped structure is formed at the connection position between the regeneration housing 310 and the heating housing 110. The two stepped surfaces of the stepped structure face the thickness direction Z and the direction from the duct outlet 312 towards the air inlet 111 respectively. By the first seal portion 1710 being located on the stepped surface facing the direction from the duct outlet 312 towards the air inlet 111, and by the second seal portion 1720 being located on the stepped surface facing the thickness direction, simultaneous sealing of the two stepped surfaces on the stepped structure is achieved, improving the sealing performance after the connection between the duct inlet 311 of the regeneration housing 310 and the air inlet 111 of the heating housing 110. At the same time, through the second seal 170 with a stepped structure, positioning during the assembly of the second seal 170 is formed, thereby improving the assembly position accuracy of the second seal 170, reducing the assembly steps, and further enhancing the sealing effect.

[0106] As Figure 13 shown, the first seal portion 1710 is provided with a fixing hole 1711. The regeneration housing 310 and the heating housing 110 are fixedly connected by a connecting member, and the connecting member passes through the fixing hole 1711. By providing the fixing hole 1711 on the first seal portion 1710 and cooperating with the connecting member, positioning and fixing of the second seal 170 are achieved, preventing the second seal 170 from being misaligned and further enhancing the sealing effect.

[0107] Among them, the connecting member can be a screw, that is, after the regenerative housing 310 and the heating housing 110 are butted, they are connected together by screws. Of course, the connecting member can also be a snap fastener, an expansion nail or other connecting members; or, the regenerative housing 310 and the heating housing 110 can also be connected by bonding or other means, and the present disclosure does not limit this.

[0108] Among them, as Figure 3 and Figure 15 shown, a convex portion 1712 is formed at the position of the fixing hole 1711 provided on the first sealing portion 1710, and a receiving groove 113 matching the convex portion 1712 is formed on the surface of the heating housing 110, and the convex portion 1712 is located in the receiving groove 113. By providing the convex portion 1712 with a larger area at the position where the fixing hole 1711 is formed, the sealing area in the circumferential direction of the fixing hole 1711 can be increased, thereby improving the sealing effect; by forming the receiving groove 113 matching the convex portion 1712 on the heating housing 110, positioning during the assembly of the second seal 170 can be formed, and the assembly efficiency and assembly accuracy of the second seal 170 can be improved.

[0109] Among them, the first sealing portion 1710 and the second sealing portion 1720 surround the air inlet 111, that is, the first sealing portion 1710 and the second sealing portion 1720 are annular sealing portions, and a sealing effect can be formed on the circumferential circle of the air duct outlet 312; as Figure 13 shown, through the annular first sealing portion 1710 and the second sealing portion 1720, sealing can be formed in the three directions of the length direction X, the width direction Y, and the thickness direction Z, further improving the sealing performance after the air duct inlet 311 of the regenerative housing 310 is connected to the air inlet 111 of the heating housing 110, avoiding air leakage between the air duct inlet 311 and the air inlet 111, and further improving the sealing effect.

[0110] Among them, at least a part of the first sealing portion 1710 is disposed between the regenerative housing 310 and the heating housing 110 along the width direction Y of the regenerative housing 310. By making the first sealing portion 1710 have a part that is located between the regenerative housing 310 and the heating housing 110 in both the thickness direction Z and the width direction Y, the first sealing portion 1710 can form a seal between the regenerative housing 310 and the heating housing 110 in the thickness direction Z and the width direction Y, and then cooperate with the second sealing portion 1720 located between the regenerative housing 310 and the heating housing 110 in the length direction X to form a seal in the three directions of the length direction X, the width direction Y, and the thickness direction Z between the regenerative housing 310 and the heating housing 110, further improving the sealing effect.

[0111] Among them, at least a part of the second sealing portion 1720 is disposed between the regeneration housing 310 and the heating housing 110 along the width direction Y of the regeneration housing 310. By making the second sealing portion 1720 have a portion that is located between the regeneration housing 310 and the heating housing 110 along both the length direction X and the width direction Y, the second sealing portion 1720 can form a seal between the regeneration housing 310 and the heating housing 110 in the length direction X and the width direction Y. Furthermore, in cooperation with the first sealing portion 1710 that is located between the regeneration housing 310 and the heating housing 110 along the thickness direction Z, a seal in three directions of the length direction X, the width direction Y, and the thickness direction Z between the regeneration housing 310 and the heating housing 110 is formed, further improving the sealing effect.

[0112] Among them, on the length direction X, width direction Y, and thickness direction Z of the regeneration housing 310, there are opposing sealing surfaces at the connection position between the air duct outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110. By making the connection position between the air duct outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110 have opposing sealing surfaces along the length direction X, width direction Y, and thickness direction Z, that is, an annular sealing surface is formed between the air duct outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110, the sealing effect between the air duct outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110 can be improved.

[0113] Among them, a second seal 170 is provided between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110, that is, the second seal 170 completely fills the gap between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110. Through the annular second seal 170, a second seal 170 is provided between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110, and thus the sealing effect between the air duct outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110 can be improved. Of course, the second seal 170 can also partially fill the gap between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110 to form a seal on the annulus, and the present disclosure does not limit this.

[0114] Among them, at least a part of the second sealing portion 1720 protrudes from the surfaces of the regeneration housing 310 and the heating housing 110 in the thickness direction Z. By making a part of the second sealing portion 1720 protrude from the surfaces of the regeneration housing 310 and the heating housing 110 in the thickness direction Z, it is convenient for the regeneration housing 310 and the heating housing 110 to be extrusion-docked in the length direction X through the second sealing portion 1720, providing assembly limit, thereby improving the assembly efficiency and assembly accuracy; at the same time, the second sealing portion 1720 provided on the protruding surface can completely seal the sealing surface of the regeneration housing 310 and the heating housing 110 at this position, thereby further improving the sealing effect. Of course, at least a part of the second sealing portion 1720 may also protrude from the surfaces of the regeneration housing 310 and the heating housing 110 in the width direction Y to further improve the sealing effect, and the present disclosure does not limit this.

[0115] Among them, the second seal 170 may be a foamed silicone part. Foamed silicone can be used for a long time and maintain its soft elastic properties in the temperature range of -65°C to 200°C, so it will not be affected by the medium and high temperature gas generated by the heating module 100; at the same time, foamed silicone is water-resistant, aging-resistant, non-corrosive, has a low linear shrinkage rate, and will not be affected by the humid environment of the clothing treatment equipment, and has stable life and elastic properties; in addition, foamed silicone is an environmentally friendly material, non-toxic, odorless, safe and hygienic; in the current market environment where users highly concern about hygiene and safety issues, using environmentally friendly materials can greatly improve the competitiveness of products in the market.

[0116] Of course, the second seal 170 may also be a rubber part, such as a rubber ring; or, the second seal 170 may also be a soft-textured corrosion-resistant metal, such as an aluminum washer or a copper washer; or, the second seal 170 may also be a plastic part, such as PA6 (nylon 66), PEEK (polyether ether ketone), PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene resin), PC (polycarbonate) or PP (polypropylene), etc., and the present disclosure does not limit this.

[0117] In one embodiment, as Figure 15 and Figure 16 shown, a raised third sealing portion 1730 is formed on the surface of the second seal 170 in contact with the heating housing 110, and the third sealing portion 1730 surrounds the through hole of the second seal 170. By providing the raised third sealing portion 1730 on the second seal 170, the degree of fit between the second seal 170 and the surface of the heating housing 110 can be further improved, thereby further improving the sealing effect.

[0118] Of course, a raised third sealing portion 1730 may also be formed on the surface of the second seal 170 that abuts against the regeneration housing 310. By providing the raised third sealing portion 1730 on the second seal 170, the degree of fit between the surface of the second seal 170 and the surface of the regeneration housing 310 can be further improved, thereby further enhancing the sealing effect.

[0119] Among them, the annularly raised third sealing portion 1730 may be provided in multiple turns, such as two turns, three turns or more; the multiple turns of the third sealing portion 1730 are sleeved together to further improve the degree of fit between the surface of the second seal 170 and the surface of the heating housing 110.

[0120] Among them, the raised third sealing portion 1730 may be formed only on the surface of the second seal 170 that abuts against the heating housing 110, or only on the surface of the second seal 170 that abuts against the regeneration housing 310, or the raised third sealing portion 1730 is formed on both the surface of the second seal 170 that abuts against the heating housing 110 and the surface of the second seal 170 that abuts against the regeneration housing 310.

[0121] In one embodiment, as Figure 2 shown, the drying module 10 is further connected to a circulation module 400. The circulation module 400 includes a blower. The air inlet of the blower is communicated with the air outlet of the laundry treatment drum 20, and the air outlet of the blower is communicated with the air inlet of the dehumidification module 200 for sending the gas to be dehumidified in the laundry treatment drum 20 into the dehumidification module 200; alternatively, the air inlet of the blower is connected to the air outlet of the dehumidification module 200, and the air inlet of the dehumidification module 200 is communicated with the air outlet of the laundry treatment drum 20. A negative pressure is formed in the dehumidification module 200 by the blower to introduce the gas to be dehumidified in the laundry treatment drum 20 into the dehumidification module 200.

[0122] The gas to be dehumidified is processed by the dehumidification module 200 to form dry gas, so that the wet circulating gas becomes dry circulating gas. The dry gas enters the laundry treatment drum 20 through the air inlet of the laundry treatment drum 20 and contacts the laundry, achieving the purpose of circulating dehumidification of the laundry in the laundry treatment drum 20.

[0123] In one embodiment, as Figure 2As shown, the drying module 10 is further connected to a condensation module 500. The condensation module 500 can condense and dehydrate the hot and humid gas after moisture desorption by the moisture absorption and discharge member 230. The water vapor of the hot and humid gas is cooled to form condensed water and discharged by the condenser, and then becomes dry and cold gas to be heated and enters the regeneration fan 320 of the heating module 100, so as to form a closed gas cycle. Of course, the dry and cold gas to be heated formed after the treatment by the condenser can also be directly discharged into the atmosphere, and the present disclosure does not limit this. Among them, the condensation module 500 may include a tube condenser, and the hot and humid gas is cooled by the tube condenser, so that the water vapor of the hot and humid gas is cooled to form condensed water and discharged by the condenser; the present disclosure does not limit the specific composition of the condensation module 500.

[0124] Among them, the gas sent into the heating module 100 by the regeneration fan 320 can be dry and cold gas after moisture desorption by the moisture absorption and discharge member 230, that is, the gas is recycled, and the humidity of the sent gas is relatively low, which can improve the drying efficiency and reduce energy consumption; or, the regeneration fan 320 of the heating module 100 can also directly suck gas from the outside.

[0125] In one embodiment, as Figure 17 shown, the dehumidification housing 201 includes a first dehumidification housing 210 and a second dehumidification housing 220. The first dehumidification housing 210 and the second dehumidification housing 220 enclose a receiving space, and at least part of the moisture absorption and discharge member 230 is in the receiving space; an air inlet is provided on one of the first dehumidification housing 210 and the second dehumidification housing 220, and an air outlet is provided on the other, and the moisture absorption and discharge member 230 is configured to be able to adsorb the moisture in the gas entering the receiving space; a hot air inlet is formed on the first dehumidification housing 210.

[0126] In one embodiment, the heating housing 110 and the dehumidification housing are detachably connected by threaded members. For example, screw hole seats are formed on the heating housing 110 of the heating module 100. When the heating housing 110 is integrally formed, the screw hole seats can be formed synchronously as the assembly area for the fixed connection between the heating module 100 and the first dehumidification housing 210, so that the heating module 100 and the first dehumidification housing 210 can be directly connected together by screws, and there is no need to provide other structures for fixing screws on the heating housing 110 of the heating module 100.

[0127] Among them, the size, quantity and distribution of the screw hole seats on the heating housing 110 can be set according to the specific structures of the heating housing 110 and the first dehumidification housing 210, and the present disclosure does not limit this.

[0128] In one embodiment, there is a first gas flow channel between the first dehumidification housing 210 and the moisture absorption and drainage member 230, and there is also a second gas flow channel between the second dehumidification housing 220 and the moisture absorption and drainage member 230. The first gas flow channel and the second gas flow form a dehumidification area of the moisture absorption and drainage member 230. The humid gas in the laundry treatment drum 20 can enter the first gas flow channel, adsorb moisture through the moisture absorption and drainage member 230, and then be discharged through the second gas flow; alternatively, the humid gas in the laundry treatment drum 20 can enter the second gas flow channel, adsorb moisture through the moisture absorption and drainage member 230, and then be discharged through the first gas flow.

[0129] Among them, the air outlet of the heating module 100 is communicated with the hot air inlet on the first dehumidification housing 210, that is, a third gas flow channel is formed between the heater 140 and the moisture absorption and drainage member 230; a fourth gas flow channel is formed between the second dehumidification housing 220 and the moisture absorption and drainage member 230, and the fourth gas flow channel of the second dehumidification housing 220 is separated from the second gas flow channel by a barrier member to separate the dehumidification area from the dehydration area. The heated high-temperature dry gas enters the third gas flow channel to desorb moisture from the moisture absorption and drainage member 230, and the humid gas after passing through the moisture absorption and drainage member 230 enters the fourth gas flow channel. During the rotation of the moisture absorption and drainage member 230, each part in the circumferential direction continuously passes through the dehumidification area and the dehydration area, so as to continuously carry out the cycle process of adsorbing moisture and desorbing moisture, and finally achieve the purpose of drying the clothes in the laundry treatment drum 20.

[0130] Among them, the dehumidification area and the dehydration area are relatively isolated, so that the dehumidification air flow in the first gas flow channel and the second gas flow and the dehydration air flow in the third gas flow channel and the fourth gas flow channel are not communicated with each other, ensuring the dehydration effect on the humid gas.

[0131] Specifically, the moisture absorption and drainage member 230 can be made of a material with good moisture absorption performance to improve the moisture adsorption capacity for the humid gas, thereby enhancing the drying effect on the clothes in the laundry treatment drum 20. The materials of the moisture absorption and drainage member 230 include, for example, lithium chloride, silica gel, zeolite, molecular sieve, etc., and the present disclosure does not limit this.

[0132] Among them, a moisture absorbent for absorbing moisture is provided on the moisture absorption and drainage member 230. The moisture absorbent can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to zeolite molecular sieve, A / X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.), polymer moisture absorbent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina and other materials with moisture absorption performance. Among them, the polymer moisture absorbent, also known as polymer adsorbent, has a lower regeneration temperature than traditional silica gel, activated carbon and molecular sieve adsorbents, etc.

[0133] Among them, the moisture absorption and moisture discharge member 230 can be made of porous materials such as zeolite, molecular sieve, Metal Organic Framework (MOF) material, Covalent Organic Frameworks (COFs), nano-carbon, and silica. In one embodiment, the moisture absorption and moisture discharge member 230 can also be formed by filling with granular solids or particles made of at least one of the above porous materials.

[0134] Among them, the moisture absorption and moisture discharge member 230 can be a honeycomb or corrugated moisture absorption and moisture discharge member carrying a moisture absorbent, which can adsorb and desorb / desorb the absorbed water vapor to achieve repeated desorption and regeneration.

[0135] Among them, the moisture absorption and moisture discharge member 230 includes an inorganic / organic fiber carrier (such as ceramics, glass fiber, MOFs, COFs, cordierite, etc.), and a moisture absorbent such as molecular sieve is coated on the fiber carrier. The molecular sieve is evenly distributed between and on the surface of the fiber carrier to achieve the adsorption of moisture in the air flow. The molecular sieve can include single crystal molecular sieves or mixed crystal molecular sieves such as type A molecular sieve, X / Y type molecular sieve, ZSM molecular sieve, Beta molecular sieve, etc.

[0136] The present disclosure does not limit the specific material of the moisture absorption and moisture discharge member 230. Any moisture absorption and moisture discharge member that can achieve the moisture absorption and moisture discharge effect belongs to the protection scope of the present disclosure.

[0137] The drying module provided by the present disclosure can be used in a laundry treatment device, and the laundry treatment device can be, for example, a washing and drying integrated machine; of course, the drying module provided by the present disclosure can also be applied to household appliances such as refrigerators, air conditioners, and dishwashers that require moisture absorption / drying.
