In household appliances that use dehumidifiers with heating and desorption properties such as molecular sieves as dehumidification modules, dry air passes through the object to be dried, takes away the moisture in the object to be dried, and becomes high-humidity air; the high-humidity air passes through the dehumidification module, absorbs moisture, becomes dry air again, and is then transported back to the object to be dried for dehumidification; the heating module precipitates moisture in the dehumidification module, thus forming a drying cycle.

[0050] In the embodiments of the present disclosure, Figure 1As shown, the clothing processing device includes a drying module 10 and a clothing processing drum 20. The clothing processing drum 20 is provided with an air inlet and an air outlet. The air outlet of the drying module 10 is connected to the air inlet of the clothing processing drum 20, and the air inlet of the drying module 10 is connected to the air outlet of the clothing processing drum 20, so that the gas in the clothing processing drum 20 is continuously dehydrated through the drying module 10, thereby achieving the purpose of drying the clothes in the clothing processing drum 20.

[0051] like Figure 2 As shown, the drying module 10 includes a heating component and a dehumidification module 200, the air outlet of the dehumidification module 200 is connected to the air inlet of the laundry treatment drum 20, and the air inlet of the dehumidification module 200 is connected to the air outlet of the laundry treatment drum 20, so as to continuously adsorb moisture in the gas in the laundry treatment drum 20 through the dehumidification module 200; the heating component can heat the airflow and / or the moisture absorption and dehumidification component 230, and the heated airflow passes through the moisture absorption and dehumidification component in the dehumidification module 200 to dehumidify and dehydrate the moisture absorption and dehumidification component, so that the moisture absorption and dehumidification component has the ability to absorb moisture again; during the rotation of the moisture absorption and dehumidification component, 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 of adsorbing and desorbing moisture, thereby achieving the purpose of drying the moisture in the laundry treatment drum 20. Among them, the moisture absorption and dehumidification component can be a rotating disk, which is convenient for passing through the dehumidification area of ​​the dehumidification module 200 and the dehydration area of ​​the heating module 100 by rotation.

[0052] In one embodiment, Figure 2 to Figure 8 As shown, the heating assembly includes a heating module 100 and a regeneration module 300. The heating module 100 includes: a heating shell 110 and a heater 120. The heating shell 110 forms a receiving space. The heating shell 110 is provided with an air inlet 111 and an air outlet 112 communicating with the receiving space. The heater 120 is arranged in the receiving space. The heater 120 is configured to heat the gas in the receiving space. The regeneration module 300 includes a regeneration shell 310 and a regeneration fan 320. The regeneration shell 310 forms a duct having an air duct inlet 311 and an air duct outlet 312. The regeneration fan 320 is arranged at the air duct inlet 311 for inputting gas into the duct. The air duct outlet 312 is connected to the air inlet 111. The sealing member 150 is arranged between the air duct outlet 312 and the air inlet 111. The sealing member 150 is configured to seal the connection gap between the air duct outlet 312 and the air inlet 111.

[0053] Among them, Figure 4 , Figures 9 to 11As shown, the sealing member 150 includes: a first sealing portion 1510 and a second sealing portion 1520, wherein the first sealing portion 1510 is arranged between the regeneration shell 310 and the heating shell 110 along the thickness direction Z of the regeneration shell 310, and the second sealing portion 1520 is arranged between the regeneration shell 310 and the heating shell 110 along the direction from the air duct outlet 312 toward the air inlet 111 (the length direction X of the regeneration shell 310).

[0054] When the air duct inlet 311 of the regeneration housing 310 is connected to the air inlet 111 of the heating housing 110, a step structure is formed at the connection position of the regeneration housing 310 and the heating housing 110, and the two step surfaces of the step structure are respectively oriented in the thickness direction Z and the direction of the air duct outlet 312 toward the air inlet 111. The first sealing part 1510 is located on the step surface pointing to the air inlet 111 in the direction of the air duct outlet 312, and the second sealing part 1520 is located on the step surface facing the thickness direction Z, so that the two step surfaces on the step structure are sealed at the same time, thereby improving the sealing performance after the air duct inlet 311 of the regeneration housing 310 is connected to the air inlet 111 of the heating housing 110; at the same time, the seal 150 with the step structure is formed to position the seal 150 during assembly, thereby improving the assembly position accuracy of the seal 150, reducing the assembly steps, and further improving the sealing effect.

[0055] like Fig. 9 As shown, a fixing hole 1511 is provided on the first sealing part 1510, and the regeneration housing 310 is fixedly connected to the heating housing 110 through a connecting piece, and the connecting piece passes through the fixing hole 1511. By providing the fixing hole 1511 on the first sealing part 1510, the sealing member 150 is positioned and fixed in cooperation with the connecting piece, so as to avoid misalignment of the sealing member 150 and further improve the sealing effect.

[0056] The connecting piece may be a screw, that is, after the regeneration housing 310 and the heating housing 110 are connected, they are connected together by screws. Of course, the connecting piece may also be a connecting piece such as a buckle or an expansion nail; or, the regeneration housing 310 and the heating housing 110 may also be connected by bonding or other methods, which is not limited in the present disclosure.

[0057] Among them, Figure 6 and Fig.11As shown, a protrusion 1512 is formed at the position of a fixing hole 1511 provided on the first sealing portion 1510, and a receiving groove 113 matching the protrusion 1512 is formed on the surface of the heating shell 110, and the protrusion 1512 is located in the receiving groove 113. By providing a protrusion 1512 with a larger area at the position where the fixing hole 1511 is formed, the sealing area of ​​the fixing hole 1511 in the circumferential direction can be increased, thereby improving the sealing effect; by forming a receiving groove 113 matching the protrusion 1512 on the heating shell 110, the sealing member 150 can be positioned during assembly, and the assembly efficiency and assembly accuracy of the sealing member 150 can be improved.

[0058] like Figure 4 and Figure 5 As shown, the first sealing portion 1510 and the second sealing portion 1520 surround the air inlet 111, that is, the first sealing portion 1510 and the second sealing portion 1520 are annular sealing portions, which can form a sealing effect on the circumference of the air duct outlet 312; Fig.13 As shown, through the annular first sealing portion 1510 and the second sealing portion 1520, sealing can be formed in three directions: length direction X, width direction Y and thickness direction Z, thereby further improving the sealing performance after the air duct inlet 311 of the regeneration shell 310 is connected to the air inlet 111 of the heating shell 110, avoiding air leakage between the air duct inlet 311 and the air inlet 111, and further improving the sealing effect.

[0059] Among them, at least part of the first sealing part 1510 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 first sealing part 1510 have a part located between the regeneration housing 310 and the heating housing 110 along both the thickness direction Z and the width direction Y, the first sealing part 1510 can form a seal between the regeneration housing 310 and the heating housing 110 in the thickness direction Z and the width direction Y, and then cooperate with the second sealing part 1520 located between the regeneration housing 310 and the heating housing 110 along the length direction X to form a seal between the regeneration housing 310 and the heating housing 110 in three directions of the length direction X, the width direction Y and the thickness direction Z, thereby further improving the sealing effect.

[0060] Among them, at least part of the second sealing part 1520 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 part 1520 have a part 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 part 1520 can form a seal between the regeneration housing 310 and the heating housing 110 in the length direction X and the width direction Y, and then cooperate with the first sealing part 1510 located between the regeneration housing 310 and the heating housing 110 along the thickness direction Z to form a seal between the regeneration housing 310 and the heating housing 110 in three directions of the length direction X, the width direction Y and the thickness direction Z, thereby further improving the sealing effect.

[0061] In which, the air duct outlet 312 of the regeneration shell 310 and the air inlet 111 of the heating shell 110 have facing sealing surfaces at the connection position in the length direction X, width direction Y and thickness direction Z of the regeneration shell 310. By making the air duct outlet 312 of the regeneration shell 310 and the air inlet 111 of the heating shell 110 have facing sealing surfaces at the connection position in 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 shell 310 and the air inlet 111 of the heating shell 110, the sealing effect between the air duct outlet 312 of the regeneration shell 310 and the air inlet 111 of the heating shell 110 can be improved.

[0062] Among them, a seal 150 is provided between the sealing surfaces facing each other of the regeneration shell 310 and the heating shell 110, that is, the seal 150 completely fills the gap between the sealing surfaces facing each other of the regeneration shell 310 and the heating shell 110. Through the annular seal 150, a seal 150 is provided between the sealing surfaces facing each other of the regeneration shell 310 and the heating shell 110, thereby improving the sealing effect between the air duct outlet 312 of the regeneration shell 310 and the air inlet 111 of the heating shell 110. Of course, the seal 150 can also partially fill the gap between the sealing surfaces facing each other of the regeneration shell 310 and the heating shell 110 to form an annular seal, and the present disclosure does not limit this.

[0063] Among them, at least part of the second sealing portion 1520 protrudes from the surface of the regeneration shell 310 and the heating shell 110 along the thickness direction Z. By making part of the second sealing portion 1520 protrude from the surface of the regeneration shell 310 and the heating shell 110 along the thickness direction Z, it is convenient for the regeneration shell 310 and the heating shell 110 to be extruded and docked in the length direction X through the second sealing portion 1520, providing assembly limit, thereby improving assembly efficiency and assembly accuracy; at the same time, the second sealing portion 1520 set on the protruding surface can enable the second sealing portion 1520 to completely seal the sealing surface of the regeneration shell 310 and the heating shell 110 at this position, thereby further improving the sealing effect. Of course, at least part of the second sealing portion 1520 can also protrude from the surface of the regeneration shell 310 and the heating shell 110 along the width direction Y to further improve the sealing effect, and the present disclosure does not limit this.

[0064] Among them, the sealing member 150 can be a foamed silicone member. Foamed silicone can be used for a long time in the temperature range of -65℃ to 200℃ and maintain its soft elastic properties, so that 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 low linear shrinkage, will not be affected by the humid environment of the clothing processing equipment, and has a stable life and elastic properties; in addition, foamed silicone is an environmentally friendly material, non-toxic, odorless, safe and hygienic; in the market environment where users are now highly concerned about health and safety issues, the use of environmentally friendly materials can greatly enhance the competitiveness of products in the market.

[0065] Of course, the seal 150 may also be a rubber part, such as a rubber ring; or, the seal 150 may also be a softer corrosion-resistant metal, such as an aluminum washer or a copper washer; or, the seal 150 may also be a plastic part, such as PA6 (nylon 66), PEEK (polyetheretherketone), PPS (polyphenylene sulfide), PTFE (polytetrafluoroethylene resin), PC (polycarbonate) or PP (polypropylene), etc., and the present disclosure does not impose any restrictions on this.

[0066] In one embodiment, Fig.11 and Fig.12 As shown, a raised third sealing portion 1530 is formed on the surface of the sealing member 150 abutting against the heating housing 110, and the third sealing portion 1530 surrounds the through hole of the sealing member 150. By providing the raised third sealing portion 1530 on the sealing member 150, the fit between the sealing member 150 and the surface of the heating housing 110 can be further improved, thereby further improving the sealing effect.

[0067] Of course, a raised third sealing portion 1530 may also be formed on the surface where the seal 150 contacts the regeneration housing 310. By providing the raised third sealing portion 1530 on the seal 150, the fit between the seal 150 and the surface of the regeneration housing 310 can be further improved, thereby further improving the sealing effect.

[0068] The third sealing portion 1530 having an annular protrusion may be provided with multiple circles, such as two circles, three circles or more circles; the multiple circles of the third sealing portion 1530 are sleeved together to further improve the fit between the sealing member 150 and the surface of the heating shell 110 .

[0069] In which, the raised third sealing portion 1530 can be formed only on the surface where the seal 150 abuts the heating shell 110, or the raised third sealing portion 1530 can be formed only on the surface where the seal 150 abuts the regeneration shell 310, or the raised third sealing portion 1530 can be formed on both the surface where the seal 150 abuts the heating shell 110 and the surface where the seal 150 abuts the regeneration shell 310.

[0070] In one embodiment, Figure 7 As shown, the heater 120 can be an electric heating tube, which is arranged in the accommodation space and heats the airflow passing through the accommodation space by heat exchange. The electric heating tube can control the output heat through the thermostat 130, thereby realizing the temperature control of the airflow heating. The electric heating tube and the thermostat 130 are used in combination to realize the precise control of the airflow temperature.

[0071] Among them, the heater 120 can be composed of multiple heating tubes connected end to end. The heating tubes are distributed at radial intervals along the sector. The length of the heating tubes is set approximately perpendicular to the radial direction of the sector. After the multiple heating tubes are connected, they 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, thereby making the efficiency of heat exchange with the gas to be heated relatively higher.

[0072] like Figure 6 and Figure 7 As shown, the heating housing 110 includes a top wall and a side wall, which enclose a receiving space, and the thermostat 130 is arranged on the side wall. By arranging the thermostat 130 on the side wall of the heating housing 110, the thermostat 130 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 an aluminum structure, injection molding is used to form an installation structure for installing the thermostat 130.

[0073] Among them, a blind hole with an opening toward the periphery can be formed on the side wall as a mounting structure, and the thermostat 130 is assembled in the blind hole. By forming a blind hole on the side wall to assemble the thermostat 130, it is possible to avoid superimposing a sealing member at the location where the thermostat 130 is installed. Of course, the thermostat 130 can also be installed by forming a through hole on the side wall, and the present disclosure does not limit this.

[0074] like Figure 6 As shown, the heating shell 110 of the heating module 100 is roughly arranged in a fan shape, that is, along the radial direction of the fan, the arc length of the end of the heating module 100 close to the rotation center of the moisture absorption and dehumidification component is smaller than the arc length away from the rotation center of the moisture absorption and dehumidification component.

[0075] Among them, the heating shell 110 is located on the top surface in a fan shape, and the side wall portion surrounds the main body portion. An air inlet 111 of the heating module 100 is formed on the side wall portion located on the outer arc surface of the fan. The gas to be heated is delivered into the heating shell 110 through the air inlet 111. After the gas is heated by the heater 120 in the heating shell 110, it flows through the dehumidification component through the air outlet 112, takes away the moisture in the dehumidification component, and realizes the desorption of moisture in the dehumidification component.

[0076] By making the heating shell 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 dehumidification component, the heating module 100 and the dehumidification module 200 can cover the surface of the moisture absorption and dehumidification component as much as possible, so that as much as possible or even all of the moisture absorption and dehumidification component is 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 capacity of the clothes in the clothing processing drum 20.

[0077] Among them, the heating shell 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 of the outer arc surface of the fan. The direction in which the heated gas enters the accommodating cavity is different from the rotation direction of the dehumidification component, which can make the heating gas have a higher flow rate relative to the dehumidification component, thereby improving the desorption effect of the heating gas on the moisture in the dehumidification component.

[0078] In one embodiment, Figure 7As shown, the heating module 100 further includes: an air guide plate 140, which is disposed between the heater 120 and the heating shell 110, and the air guide plate 140 and the heating shell 110 are spaced apart, and an air flow channel is formed between the air guide plate 140 and the heating shell 110, and the air flow hole is connected to the air inlet 111 of the heating module 100, and after the heated gas enters the air flow channel between the air guide plate 140 and the heating shell 110, it flows through the multiple heating tubes in the heater 120 under the guidance of the air guide plate 140; the air guide plate 140 is provided with multiple ventilation holes, and at least some of the ventilation holes are arranged opposite to the heating tubes. The air guide plate 140 can make the heated gas enter the heater 120 more evenly for heating.

[0079] Among them, a plurality of air holes can be arranged in a row along the radial direction of the fan, and the arrangement position of each row of air holes roughly corresponds to the position of the heating tube, and the diameter of the air holes gradually increases from the outer arc to the center of the circle along the radial direction of the fan. The air inlet 111 of the heating module 100 is located on the outer arc side of the heating shell 110, and the diameter of the air holes near the air inlet 111 is relatively small, and the diameter of the air holes away from the air inlet 111 is relatively large, that is, the diameter of the air holes near the air inlet 111 is smaller than the diameter of the air holes away from the air inlet 111, thereby ensuring that the gas flow of each air hole is roughly the same, so that the gas to be heated can enter the heater 120 more evenly for heating, thereby improving the heating efficiency.

[0080] In one embodiment, Fig.13 As shown, the dehumidification module 200 includes a dehumidification shell 201 and a dehumidification component 230. The dehumidification shell 201 forms a accommodating space. The dehumidification shell 201 is provided with an air inlet and an air outlet connected to the accommodating space. The air outlet of the dehumidification shell 201 is connected to the air inlet of the clothing processing drum 20. The air inlet of the dehumidification shell 201 is connected to the air outlet of the clothing processing drum 20. At least part of the dehumidification component 230 is arranged in the accommodating space.

[0081] Among them, the dehumidification shell 201 includes a first dehumidification shell 210 and a second dehumidification shell 220, and the first dehumidification shell 210 and the second dehumidification shell 220 are enclosed to form a accommodating space, in which at least part of the accommodating space of the dehumidification component 230 is located; one of the first dehumidification shell 210 and the second dehumidification shell 220 is provided with an air inlet, and the other is provided with an air outlet, and the dehumidification component 230 is configured to be able to absorb moisture in the gas entering the accommodating space; a hot air inlet is formed on the first dehumidification shell 210.

[0082] Among them, Fig.13As shown, a hot air inlet 211 is provided on the first dehumidification shell 210, and the dehumidification component 230 is configured to absorb moisture in the gas entering the accommodating space; the heating module 100 is fixed on the first dehumidification shell 210 so that the air outlet 112 is connected to the hot air inlet 211; at least a part of the dehumidification component 230 is arranged opposite to the air outlet 112 on the heating module 100, and the heating module 100 is configured to dehydrate the part of the dehumidification component 230 located at the air outlet 112.

[0083] In one embodiment, Figure 2 As shown, the drying module 10 is also connected to a circulation module 400, which includes an air blower, whose air inlet is connected to the air outlet of the clothing treatment drum 20, and whose air outlet is connected to the air inlet of the dehumidification module 200, so as to supply the gas to be dehumidified in the clothing treatment drum 20 into the dehumidification module 200; or, the air inlet of the air blower is connected to the air outlet of the dehumidification module 200, and whose air inlet is connected to the air outlet of the clothing treatment drum 20, so as to form a negative pressure in the dehumidification module 200 by the air blower, so as to introduce the gas to be dehumidified in the clothing treatment drum 20 into the dehumidification module 200.

[0084] The dehumidified gas 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 clothing processing drum 20 through the air inlet of the clothing processing drum 20 and contacts the clothes, thereby achieving the purpose of circulating dehumidification of the clothes in the clothing processing drum 20.

[0085] In one embodiment, Figure 2 As shown, the drying module 10 is also connected to a condensation module 500, which can condense and dehydrate the hot and humid gas after the moisture absorption and dehumidification component 230 has been used for desorption of moisture. The water vapor in the hot and humid gas is cooled to form condensed water and discharged from the condenser, and becomes dry and cold gas to be heated and enters the regeneration fan 320 of the heating module 100, so that the gas forms a closed loop. Of course, the dry and cold gas to be heated formed after the condenser treatment 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 tubular condenser, and the hot and humid gas is cooled by the tubular condenser, so that the water vapor in the hot and humid gas is cooled to form condensed water and discharged from the condenser; the present disclosure does not limit the specific composition of the condensation module 500.

[0086] Among them, the gas delivered to the heating module 100 through the regeneration fan 320 can be dry cold gas after moisture is desorbed by the moisture absorption and dehumidification component 230, that is, the gas is recycled, and the humidity of the delivered 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 inhale gas from the outside.

[0087] In one embodiment, the heating housing 110 is detachably connected to the dehumidification housing via a screw member. For example, a screw hole seat is formed on the heating housing 110 of the heating module 100. When the heating housing 110 is formed by integral molding, the screw hole seat can be simultaneously formed as an assembly area for fixing 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, without the need to set other fixing screw structures on the heating housing 110 of the heating module 100.

[0088] The size, quantity and distribution of the screw holes 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 impose any restrictions on this.

[0089] In one embodiment, a first gas flow channel is provided between the first dehumidification shell 210 and the moisture absorption and dehumidification component 230, and a second gas flow channel is provided between the second dehumidification shell 220 and the moisture absorption and dehumidification component 230. The first gas flow channel and the second gas flow form a dehumidification area of ​​the moisture absorption and dehumidification component 230. The humid gas in the clothing treatment drum 20 can enter the first gas flow channel, absorb moisture through the moisture absorption and dehumidification component 230, and then be discharged through the second gas flow; or, the humid gas in the clothing treatment drum 20 can enter the second gas flow channel, absorb moisture through the moisture absorption and dehumidification component 230, and then be discharged through the first gas flow.

[0090] Among them, the air outlet of the heating module 100 is connected to the hot air inlet on the first dehumidification shell 210, that is, a third gas flow channel is formed between the heater 120 and the moisture absorption and dehumidification component 230; a fourth gas flow channel is formed between the second dehumidification shell 220 and the moisture absorption and dehumidification component 230, and the fourth gas flow channel of the second dehumidification shell 220 is separated from the second gas flow channel by a barrier 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 dehumidification component 230, and the humid gas after passing through the moisture absorption and dehumidification component 230 enters the fourth gas flow channel. During the rotation of the moisture absorption and dehumidification component 230, various parts in the circumferential direction continuously pass through the dehumidification area and the dehydration area, thereby continuously performing a cycle of adsorbing and desorbing moisture, and finally achieving the purpose of drying the clothes in the clothing treatment drum 20.

[0091] The dehumidification area and the dehydration area are relatively isolated so that the dehumidification airflow in the first gas flow channel and the second gas flow and the dehydration airflow in the third gas flow channel and the fourth gas flow channel are not connected to each other, thereby ensuring the dehydration effect on the humid gas.

[0092] Specifically, the moisture absorption and dehumidification member 230 can be made of a material with good moisture absorption performance to improve the moisture absorption capacity of humid gas, thereby improving the drying effect of the clothes in the laundry treatment drum 20. The material of the moisture absorption and dehumidification member includes, for example, lithium chloride, silica gel, zeolite, molecular sieve, etc., which is not limited in the present disclosure.

[0093] The moisture absorption and dehumidification member 230 is provided with a moisture absorbent for absorbing moisture. The moisture absorbent may 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 properties. The polymer moisture absorbent is also called a polymer adsorbent, which has a lower regeneration temperature than traditional silica gel, activated carbon, and molecular sieve adsorbents.

[0094] The moisture absorption and dehumidification member 230 may be made of porous materials such as zeolite, molecular sieve, metal organic framework (MOF) material, covalent organic framework (COFs), nanocarbon, silicon dioxide, etc. In one embodiment, the moisture absorption and dehumidification member 230 may also be formed by granular solid or particle filling including at least one of the above-mentioned porous materials.

[0095] The moisture absorption and dehumidification member 230 may be a honeycomb or corrugated moisture absorption and dehumidification member carrying a desiccant, which can adsorb and desorb / desorb the absorbed water vapor to achieve repeated desorption and regeneration.

[0096] The moisture absorption and dehumidification member 230 includes an inorganic / organic fiber carrier (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.), and the fiber carrier is coated with a moisture absorbent such as a molecular sieve, and the molecular sieve is evenly distributed between the fiber carriers and on the surface of the fiber carrier to achieve the adsorption of airflow moisture. The molecular sieve may include single crystal molecular sieves or mixed crystal molecular sieves such as A-type molecular sieve, X / Y-type molecular sieve, ZSM molecular sieve, and Beta molecular sieve.

[0097] The present disclosure does not limit the specific material of the moisture absorption and dehumidification component 230. Any moisture absorption and dehumidification component that can achieve the moisture absorption and dehumidification effect belongs to the protection scope of the present disclosure.

[0098] The drying module provided in the present disclosure can be used in clothing processing equipment, and the clothing processing equipment can be, for example, a washing and drying machine; of course, the drying module provided in the present disclosure can also be applied to household appliances that require moisture absorption / drying, such as refrigerators, air conditioners, and dishwashers.
