Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and more specifically, to a heating module, a drying module, and a clothing processing device. Background Technology

[0002] With the improvement of living standards, many household appliances with drying functions have emerged to dry objects, providing great convenience to people's lives. In household appliances that use desiccant with heating desorption properties, such as molecular sieves, as dehumidification modules, dry air passes through the object to be dried, carrying away the moisture in the object and becoming high-humidity air. The high-humidity air then passes through the dehumidification module, absorbs moisture, becomes dry air again, and is then sent back to the object to be dried for dehumidification. The heating module removes the moisture from the dehumidification module, thus forming a drying cycle.

[0003] However, the existing heating modules are relatively complex in structure and assembly, and the coordination between the heating module and the dehumidification module is also quite complicated.

[0088] Exemplary embodiments will now be described more fully with reference to the accompanying drawings.

It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0090] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0091] In embodiments of this disclosure, such as Figure 1 As shown, the clothing processing equipment 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 drying module 10 continuously dehydrates the gas in the clothing processing drum 20, thereby achieving the purpose of drying the clothes in the clothing processing drum 20.

[0092] like Figure 2 As shown, the drying module 10 includes a heating module 100 and a dehumidification module 200. The air outlet of the dehumidification module 200 is connected to the air inlet of the clothes processing drum 20, and the air inlet of the dehumidification module 200 is connected to the air outlet of the clothes processing drum 20, so that the dehumidification module 200 continuously adsorbs moisture in the gas in the clothes processing drum 20. The heating module 100 can heat the airflow and / or the moisture absorption and dehumidification component 230. 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 can adsorb moisture again. During the rotation of the moisture absorption and dehumidification component, it passes through the dehumidification zone of the dehumidification module 200 and the dehydration zone of the heating module 100, and continuously carries out the cycle of adsorbing and desorbing moisture, thereby achieving the purpose of drying the clothes in the clothes processing drum 20. The moisture absorption and dehumidification component can be a turntable, which facilitates the rotation of the dehumidification zone of the dehumidification module 200 and the dehydration zone of the heating module 100.

[0093] In one embodiment, such as Figures 3-6As shown, the heating module 100 includes: a heating housing 110, a heater 140, and a first sealing member 130. The heating housing 110 forms a receiving space, and the heating housing 110 is provided with an air inlet 111 and an air outlet 112 communicating with the receiving space. A groove 120 is formed on the heating housing 110 surrounding the air outlet 112. The heater 140 is disposed in the receiving space and is configured to heat the gas in the receiving space. The first sealing member 130 is disposed in the groove 120.

[0094] The heating module 100 provided in this disclosure can heat the gas in the containment space through the heater 140 to provide heated gas at a preset temperature. When the heating module 100 provides 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 to ensure the temperature of the heated gas and prevent air leakage. A groove 120 is formed on the heating housing 110 of this disclosure around the air outlet 112, and a first sealing element 130 is provided in the groove 120. When the dehumidifier housing is sealed, the sealing structure on the dehumidifier housing can extend into the groove 120 and abut against the first sealing element 130, thereby forming a sealed connection. In addition, the groove 120 serves two purposes: firstly, it facilitates the installation of the first sealing element 130, allowing it to deform within the groove 120 when compressed, preventing misalignment and sealing failure; secondly, the groove 120 provides a mating position for the sealing connection between the heating housing 110 and the dehumidifier module 200, further improving the sealing effect and reducing assembly steps.

[0095] like Figure 4 As shown, the opening of the groove 120 faces the same direction as the air outlet 112. By making the opening of the groove 120 face the same direction as 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 sealing element 130 in the groove 120 in the mating direction, and thus improving the sealing effect.

[0096] like Figure 5 and Figure 6 As shown, the groove 120 is an annular groove surrounding the air outlet 112, and the first sealing element 130 is a sealing ring located in the annular groove. By setting the groove 120 to be annular, an annular groove can be formed around the air outlet 112. In conjunction with the use of the sealing ring as the first sealing element 130, a sealing effect can be formed around the air outlet 112, preventing air leakage and further improving the sealing effect.

[0097] The first sealing element 130 can be made of foamed silicone. Foamed silicone can be used for a long time within a temperature range of -65℃ to 200℃ while maintaining its soft and elastic properties, thus avoiding the effects of medium- and high-temperature gases generated by the heating module 100. Simultaneously, foamed silicone is water-resistant, aging-resistant, non-corrosive, and has a low linear shrinkage rate, unaffected by the humid environment of clothing processing equipment, exhibiting stable lifespan and elasticity. Furthermore, foamed silicone is an environmentally friendly material, non-toxic, odorless, safe, and hygienic. In today's market environment where users are highly concerned about hygiene and safety, using environmentally friendly materials can significantly enhance the product's competitiveness in the market.

[0098] 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 softer corrosion-resistant metal, such as an aluminum gasket or a copper gasket; 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 this disclosure does not limit it.

[0099] In this design, 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 improves the stability of the first seal 130 in the groove 120 and facilitates the assembly of the first seal 130 in the groove 120. In addition, when the groove 120 is engaged with the sealing structure of the dehumidifying housing, the portion of the groove 120 that is higher than the first seal 130 can form a guide for the sealing structure to extend into the groove 120.

[0100] 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 determine whether the first seal 130 is installed flat and in place, thus facilitating 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 this disclosure does not impose any restrictions on this.

[0101] 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 effect can be formed on the first seal 130 through the side wall of the groove 120, so that the first seal 130 is pre-fixed in the groove 120, thereby preventing the first seal 130 from moving or misaligning after being assembled in the groove 120, thereby improving the sealing effect provided by the first seal 130.

[0102] In this case, the width of the groove 120 can 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 assembling the first seal 130 in the groove 120, the left and right gaps of the first seal 130 in the groove 120 can be observed to determine whether the first seal 130 is installed flat and in place, thus facilitating the assembly of the first seal 130. Of course, the width of the groove 120 can also be greater than the width of the first seal 130 to allow for deformation accommodation space after the first seal 130 is subjected to compression deformation; this disclosure does not impose any limitations on this.

[0103] In this design, the width of the groove 120 decreases as its opening faces the bottom, meaning the cross-section of the groove 120 is trapezoidal. When the first sealing element 130 is assembled in the groove 120, the larger opening of the groove 120 facilitates the placement of the first sealing element 130. The decreasing width of the groove 120 towards the bottom allows the first sealing element 130 to be tightly fixed within the groove 120. Simultaneously, when the first sealing element 130 is subjected to external pressure, it can deform towards the bottom, further enhancing the sealing effect within the groove 120. Of course, the width of the groove 120 can also be the same or increasing as its opening faces the bottom; this disclosure does not impose any limitations on this.

[0104] like Figure 6 As shown, in the depth direction of the groove 120, the height of the sidewall of the groove 120 near the heater 140 is higher than the height of the sidewall away from the heater 140. That is, the height of the groove 120 relative to the sidewall near the outside of the heating housing 110 is relatively smaller. By making the height of the groove 120 relatively smaller relative to the sidewall near the outside of the heating housing 110, when the groove 120 is fitted with the sealing structure of the dehumidification housing, the higher inner sidewall of the groove 120 can provide lateral positioning for the sealing structure, improving assembly efficiency. At the same time, the higher inner sidewall of the groove 120 can better block hot air, further preventing air leakage.

[0105] When the height of the groove 120 relative to the two side walls is not the same, the depth of the groove 120 is the height of the lower side wall.

[0106] like Figure 6 As shown, the heating housing 110 includes a main body 1110, a side wall 1120, and an extension 1130. The side wall 1120 and the main body 1110 enclose a receiving space. The extension 1130 is located around the side wall 1120, and the extension 1130 and the side wall 1120 enclose a groove 120. By providing the extension 1130 and the side wall 1120 to enclose a groove 120, the original structure of the side wall 1120 is preserved, that is, the thickness of the side wall 1120 can maintain its original thickness. At the same time, by preserving the original structure of the side wall 1120, the receiving space formed by the side wall 1120 and the main body 1110 can maintain its original shape, avoiding any impact on the flow of gas in the receiving space.

[0107] The wall thickness of the extension portion 1130 is greater than that of the side wall portion 1120. Since the extension portion 1130 forms a groove 120 by connecting the extension portion 1130 to the side wall portion 1120, and by setting the thickness of the extension portion 1130 to be larger, the extension portion 1130 can have greater structural strength when assembling the heating shell 110, thus preventing the groove 120 from deforming and causing a reduction or even failure of the sealing effect.

[0108] Wherein, the wall thickness of the extension portion 1130 is a, and the wall thickness of the side wall portion 1120 is b, where 1 < a : b < 3; of course, the wall thickness of the extension portion 1130 may be equal to or less than the wall thickness of the side wall portion 1120, and this disclosure does not impose any restrictions on this.

[0109] like Figure 3 The air inlet 111 is located 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, the open end serving as the air outlet 112.

[0110] like Figure 4 The heater 140 is an electric heating element, which is coiled within the receiving space to heat the airflow passing through the space through heat exchange. The output heat of the electric heating element can be controlled by the temperature controller 150, thereby achieving temperature control of the airflow. By using the electric heating element in conjunction with the temperature controller 150, precise control of the airflow temperature can be achieved.

[0111] like Figure 3As shown, the heating housing 110 includes a top wall and a side wall, which together form an accommodating space. The thermostat 150 is disposed on the side wall. By placing the thermostat 150 on the side wall of the heating housing 110, the thermostat 150 is closer to the actual temperature of the heating element, resulting in more precise temperature control. Furthermore, when the heating housing 110 is made of aluminum, injection molding facilitates the formation of an installation structure for the thermostat 150.

[0112] One option is to form a blind hole with an opening facing outwards on the side wall as a mounting structure, into which the thermostat 150 is assembled. By assembling the thermostat 150 through a blind hole in the side wall, it is possible to avoid stacking a seal at the location where the thermostat 150 is installed. Of course, the thermostat 150 can also be installed by forming a through hole in the side wall; this disclosure does not impose any limitation on this method.

[0113] like Figures 3-6 As shown, the heating housing 110 of the heating module 100 is roughly fan-shaped, that is, along the radial direction of the fan, the arc length of the end of the heating module 100 near the rotation center of the moisture absorption and desiccation component is smaller than the arc length away from the rotation center of the moisture absorption and desiccation component.

[0114] The heating housing 110 has a fan-shaped main body portion 1110 on its top surface. 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 on the outer arc surface of the fan shape. Gas to be heated is introduced into the heating housing 110 through the air inlet 111. After being heated by the heater 140 inside the heating housing 110, the gas flows through the air outlet 112 and passes through the moisture absorption and dehumidification component, carrying away the moisture in the moisture absorption and dehumidification component, thereby achieving the desorption of moisture in the moisture absorption and dehumidification component.

[0115] By making the heating housing 110 of the heating module 100 fan-shaped, when the heating module 100 and the dehumidification module 200 cooperate, 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 or even all of the moisture absorption and dehumidification component is located in the dehumidification area formed by the dehumidification module 200 and the dehydration area formed by the heating module 100 respectively, thereby relatively improving the drying capacity of clothes in the clothes treatment drum 20.

[0116] The heating housing 110 of the heating module 100 is fan-shaped, and the air inlet 111 of the heating module 100 is formed on the side wall 1120 of the outer arc surface of the fan. The direction of the gas to be heated entering the receiving cavity is different from the rotation direction of the moisture absorption and dehumidification component, which enables the heating gas to have a higher flow rate relative to the moisture absorption and dehumidification component, thereby improving the desorption effect of the heating gas on the moisture absorption and dehumidification component.

[0117] Among them, such as Figure 4As shown, the heater 140 can be composed of multiple heating tubes connected end to end. The heating tubes are distributed radially along a fan shape, and the length of the heating tubes is approximately perpendicular to the radial direction of the fan shape. After the multiple heating tubes are connected, they are distributed in an S-shape. The heating tubes are relatively longer in the accommodating area, which can increase the contact area with the gas to be heated, thereby increasing the efficiency of heat exchange with the gas to be heated.

[0118] like Figure 4 As shown, the heating module 100 further includes: an air guide plate 160, which is disposed between the heater 140 and the main body 1110, and the air guide plate 160 and the main body 1110 are spaced apart, forming an airflow channel between the air guide plate 160 and the main body 1110. This airflow channel is connected to the air inlet 111 of the heating module 100. After the gas to be heated enters the airflow channel formed between the air guide plate 160 and the main body 1110, it flows through the multiple heating tubes in the heater 140 under the guidance of the air guide plate 160. The air guide plate 160 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 160 allows the gas to be heated to enter the heater 140 more evenly for heating.

[0119] Multiple air vents are arranged in rows along the radial direction of a fan shape. The position of each row of air vents roughly corresponds to the position of the heating tube. The diameter of the air vents gradually increases from the outer arc to the center along the radial direction of the fan shape. The air inlet 111 of the heating module 100 is located on the outer arc side of the heating housing 110. The diameter of the air vents near the air inlet 111 is relatively smaller, while the diameter of the air vents further away from the air inlet 111 is relatively larger. That is, the diameter of the air vents near the air inlet 111 is smaller than the diameter of the air vents further away from the air inlet 111, thereby ensuring that the gas flow rate of each air vent is approximately the same, allowing the gas to be heated to enter the heater 140 more evenly for heating and improving heating efficiency.

[0120] In one embodiment, such as Figure 2 As shown, the drying module 10 includes a dehumidification module 200 and a heating module 100. Figure 17 As shown, the dehumidification module 200 includes a moisture-absorbing and dehumidifying component 230 and a dehumidification housing. The dehumidification housing forms an accommodating space, and has an air inlet and an air outlet communicating with the accommodating space. The air outlet of the dehumidification housing is connected to the air inlet of the clothes handling drum 20, and the air inlet of the dehumidification housing is connected to the air outlet of the clothes handling drum 20. At least a portion of the moisture-absorbing and dehumidifying component 230 is disposed in the accommodating space; Figure 7As shown, the first dehumidification housing 210 is provided with a hot air inlet 212, and the moisture absorption and dehumidification component 230 is configured to absorb moisture from the gas entering the accommodating space; the heating module 100 is fixed on the first dehumidification housing 210, and at least a portion of the moisture absorption and dehumidification component 230 is disposed opposite to the air outlet 112 on the heating module 100, and the heating module 100 is configured to dehydrate the portion of the moisture absorption and dehumidification component 230 located at the air outlet 112.

[0121] like Figure 7 As shown, the first dehumidifying housing 210 is provided with a connecting portion 211, and a hot air inlet 212 is formed on the connecting portion 211. 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 protrusion 213 is formed on the connecting portion 211 surrounding the hot air inlet 212. The protrusion 213 is correspondingly provided with a groove 120. In the installed state, the protrusion 213 is at least partially located in the groove 120. When the heating housing 110 and the first dehumidifying housing 210 of the dehumidifying module 200 are sealed together, the protrusion 213 on the first dehumidifying housing 210 can extend into the groove 120 and abut against the first sealing member 130, thereby forming a sealed connection. In addition, the groove 120 and the protrusion 213 cooperate to form a mating positioning for the sealing connection between the heating housing 110 and the first dehumidifying housing 210, thereby further improving the sealing effect and reducing assembly steps.

[0122] In this design, the distance between the protrusion 213 and the bottom of the groove 120 in the depth direction of the groove 120 is less than the thickness of the first seal 130 in its free state. By making the distance between the protrusion 213 and the bottom of the groove 120 less than the thickness of the first seal 130 in its free state, when the protrusion 213 is located in the groove 120, it can compress the first seal 130 in the groove 120, thereby deforming the first seal 130 and improving the sealing effect.

[0123] When the groove 120 forms an annular shape around the air outlet 112, the protrusion 213 also forms an annular protrusion around the hot air inlet 212. The annular protrusion is located in the annular groove and achieves circumferential sealing with the annular sealing ring to avoid air leakage and improve the sealing effect.

[0124] In one embodiment, such as Figures 8 to 13As shown, the drying module 10 also includes a regeneration module 300 and a second sealing element 170. The regeneration module 300 includes a regeneration housing 310 and a regeneration fan 320. The regeneration housing 310 forms an air duct with an air duct inlet 311 and an air duct outlet 312. The regeneration fan 320 is located at the air duct inlet 311 and is used to input gas into the air duct. The air duct outlet 312 is connected to the air inlet 111. The second sealing element 170 is located between the air duct outlet 312 and the air inlet 111. The second sealing element 170 is configured to seal the connection gap between the air duct outlet 312 and the air inlet 111.

[0125] like Figures 13-15 As shown, the second sealing element 170 includes: a first sealing part 1710 and a second sealing part 1720. The first sealing part 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 sealing part 1720 is disposed between the regeneration housing 310 and the heating housing 110 along the direction from the air duct outlet 312 toward the air inlet 111 (the length direction X of the regeneration housing 310).

[0126] When the air duct inlet 311 of the regenerated housing 310 is connected to the air inlet 111 of the heating housing 110, a stepped structure is formed at the connection point between the regenerated housing 310 and the heating housing 110. The two stepped surfaces of the stepped structure face the thickness direction Z and the direction of the air duct outlet 312 towards the air inlet 111, respectively. By having the first sealing part 1710 located on the stepped surface facing the direction of the air duct outlet 312 towards the air inlet 111, and the second sealing part 1720 located on the stepped surface facing the thickness direction, both stepped surfaces of the stepped structure are simultaneously sealed, improving the sealing performance after the air duct inlet 311 of the regenerated housing 310 is connected to the air inlet 111 of the heating housing 110. At the same time, the second sealing member 170 with the stepped structure forms a positioning for the second sealing member 170 during assembly, thereby improving the assembly position accuracy of the second sealing member 170, reducing assembly steps, and further improving the sealing effect.

[0127] like Figure 13 As shown, the first sealing part 1710 is provided with a fixing hole 1711. The regeneration housing 310 and the heating housing 110 are fixedly connected by a connector, which passes through the fixing hole 1711. By providing a fixing hole 1711 on the first sealing part 1710, the second sealing element 170 is positioned and fixed in conjunction with the connector, preventing misalignment of the second sealing element 170 and further improving the sealing effect.

[0128] The connector can be a screw, meaning that the regenerated housing 310 and the heating housing 110 are connected together using screws after they are mated. Of course, the connector can also be a snap-fit, expansion bolt, or other connector; or, the regenerated housing 310 and the heating housing 110 can also be connected by adhesive or other means, and this disclosure does not limit this.

[0129] Among them, such as Figure 3 and Figure 15 As shown, a protrusion 1712 is formed at the location of the fixing hole 1711 on the first sealing part 1710. A receiving groove 113 matching the protrusion 1712 is formed on the surface of the heating housing 110, and the protrusion 1712 is located in the receiving groove 113. By providing a protrusion 1712 with a larger area at the location 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 a receiving groove 113 matching the protrusion 1712 on the heating housing 110, positioning can be formed during the assembly of the second sealing member 170, thereby improving the assembly efficiency and assembly accuracy of the second sealing member 170.

[0130] The first sealing part 1710 and the second sealing part 1720 surround the air inlet 111, that is, the first sealing part 1710 and the second sealing part 1720 are annular sealing parts, which can form a sealing effect around the circumference of the air duct outlet 312; such as Figure 13 As shown, the annular first sealing part 1710 and the second sealing part 1720 can form a seal in three directions: length direction X, width direction Y and thickness direction Z, which further improves the sealing performance after the air duct inlet 311 of the regenerated housing 310 is connected to the air inlet 111 of the heating housing 110, avoids air leakage between the air duct inlet 311 and the air inlet 111, and further improves the sealing effect.

[0131] At least a portion of the first sealing portion 1710 is disposed between the regeneration housing 310 and the heating housing 110 along the width direction Y of the regeneration housing 310. By having the first sealing portion 1710 located between the regeneration housing 310 and the heating housing 110 simultaneously along the thickness direction Z and the width direction Y, the first sealing portion 1710 can form a seal between the regeneration housing 310 and the heating housing 110 in the thickness direction Z and the width direction Y. Furthermore, in conjunction with the second sealing portion 1720 located between the regeneration housing 310 and the heating housing 110 along the length direction X, a seal is formed between the regeneration housing 310 and the heating housing 110 in three directions: the length direction X, the width direction Y, and the thickness direction Z, further improving the sealing effect.

[0132] At least a portion 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 having the second sealing portion 1720 located between the regeneration housing 310 and the heating housing 110 simultaneously along 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. This, combined with the first sealing portion 1710 located between the regeneration housing 310 and the heating housing 110 along the thickness direction Z, forms a seal between the regeneration housing 310 and the heating housing 110 in three directions: the length direction X, the width direction Y, and the thickness direction Z, further improving the sealing effect.

[0133] In this design, the air outlet 312 of the regenerating housing 310 and the air inlet 111 of the heating housing 110 have opposing sealing surfaces at their connection points along the length (X), width (Y), and thickness (Z) of the regenerating housing 310. By ensuring that the air outlet 312 of the regenerating housing 310 and the air inlet 111 of the heating housing 110 have opposing sealing surfaces along the length (X), width (Y), and thickness (Z) of their connection points, i.e., forming an annular sealing surface between the air outlet 312 of the regenerating housing 310 and the air inlet 111 of the heating housing 110, the sealing effect between the air outlet 312 of the regenerating housing 310 and the air inlet 111 of the heating housing 110 can be improved.

[0134] In this design, a second sealing element 170 is provided between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110, meaning the second sealing element 170 completely fills the gap between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110. The annular second sealing element 170 ensures that the sealing effect between the air outlet 312 of the regeneration housing 310 and the air inlet 111 of the heating housing 110 is improved. Of course, the second sealing element 170 can also partially fill the gap between the opposing sealing surfaces of the regeneration housing 310 and the heating housing 110 to form an annular seal; this disclosure does not impose any limitations on this.

[0135] At least a portion of the second sealing portion 1720 protrudes along the thickness direction Z from the surfaces of the regenerated housing 310 and the heating housing 110. By making a portion of the second sealing portion 1720 protrude along the thickness direction Z from the surfaces of the regenerated housing 310 and the heating housing 110, the regenerated housing 310 and the heating housing 110 can be pressed together in the length direction X through the second sealing portion 1720, providing assembly limits and thus improving assembly efficiency and assembly accuracy. At the same time, the second sealing portion 1720, which is provided on the protruding surface, can completely seal the sealing surfaces of the regenerated housing 310 and the heating housing 110 at that position, thereby further improving the sealing effect. Of course, at least a portion of the second sealing portion 1720 may also protrude along the width direction Y from the surfaces of the regenerated housing 310 and the heating housing 110 to further improve the sealing effect; this disclosure does not limit this.

[0136] The second sealing element 170 can be made of foamed silicone. Foamed silicone can be used for a long time within a temperature range of -65℃ to 200℃ while maintaining its soft and elastic properties, thus avoiding the effects of medium- and high-temperature gases generated by the heating module 100. Simultaneously, foamed silicone is water-resistant, aging-resistant, non-corrosive, and has a low linear shrinkage rate, unaffected by the humid environment of clothing processing equipment, exhibiting stable lifespan and elasticity. Furthermore, foamed silicone is an environmentally friendly material, non-toxic, odorless, safe, and hygienic. In today's market environment where users are highly concerned about hygiene and safety, using environmentally friendly materials can significantly enhance the product's competitiveness in the market.

[0137] Of course, the second seal 170 can also be a rubber part, such as a rubber ring; or, the second seal 170 can also be a softer, corrosion-resistant metal, such as an aluminum gasket or a copper gasket; or, the second seal 170 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 this disclosure does not limit it.

[0138] In one embodiment, such as Figure 15 and Figure 16 As shown, a raised third sealing portion 1730 is formed on the surface of the second sealing member 170 that abuts against the heating housing 110, and the third sealing portion 1730 surrounds the through hole of the second sealing member 170. By providing the raised third sealing portion 1730 on the second sealing member 170, the fit between the second sealing member 170 and the surface of the heating housing 110 can be further improved, thereby further improving the sealing effect.

[0139] Of course, a raised third sealing portion 1730 may also be formed on the surface where the second sealing member 170 abuts against the regeneration housing 310. By providing a raised third sealing portion 1730 on the second sealing member 170, the fit between the surfaces of the second sealing member 170 and the regeneration housing 310 can be further improved, thereby further improving the sealing effect.

[0140] The annular protrusion of the third sealing part 1730 can be provided with multiple rings, such as two, three or more rings; the multiple rings of the third sealing part 1730 are sleeved together to further improve the fit between the second sealing member 170 and the surface of the heating housing 110.

[0141] The raised third sealing portion 1730 may be formed only on the surface where the second sealing member 170 abuts against the heating housing 110, or only on the surface where the second sealing member 170 abuts against the regeneration housing 310, or the raised third sealing portion 1730 may be formed on both the surface where the second sealing member 170 abuts against the heating housing 110 and the surface where the second sealing member 170 abuts against the regeneration housing 310.

[0142] In one embodiment, such as Figure 12 and Figure 17 As shown, the regeneration module 300 includes: a regeneration housing 310, a regeneration fan 320, and a flow guide 330. The regeneration housing 310 forms a duct with an air duct inlet 311 and an air duct outlet 312. The regeneration fan 320 is located at the air duct inlet 311. The flow guide 330 is located inside the air duct and is configured to guide the airflow inside the air duct so that the air outlet 312 is uniformly vented.

[0143] The regeneration module 300 provided in this disclosure delivers gas supplied by the regeneration fan 320 through the regeneration housing 310. When the gas is delivered through the regeneration housing 310, the air volume at various locations of the air duct outlet 312 varies. By setting the guide element 330 in the air duct, the gas in the air duct can be guided to make the air outlet 312 relatively uniform, thereby improving the uniformity of the air outlet 312 and enhancing the air delivery effect.

[0144] like Figure 17As shown, the guide member 330 extends from the duct inlet 311 towards the duct outlet 312. By extending the guide member 330 from the duct inlet 311 towards the duct outlet 312, the duct can be divided into multiple sub-ducts in the width direction to achieve airflow distribution within the duct. For example, if the airflow on one side is greater than that on the other side in the width direction, the inlet area on the side with the larger airflow can be relatively reduced, and the inlet area on the side with the smaller airflow can be relatively increased. The outlet areas of the multiple sub-ducts can be the same, thereby adjusting the airflow in the duct through the airflow equalization member to make the airflow at the duct outlet 312 tend to be uniform.

[0145] like Figure 12 As shown, the regeneration fan 320 can be a centrifugal fan, and the shaft of the centrifugal fan is arranged along the height direction of the regeneration housing 310. In the rotation direction around the shaft, the guide member 330 divides the air duct into two sub-air ducts with a first air duct inlet, a second air duct inlet, a first air duct outlet, and a second air duct outlet. The second air duct inlet is located on the side of the first air duct inlet facing the rotation direction, and the second air duct outlet is located on the side of the first air duct outlet facing the rotation direction.

[0146] The ratio of the area of ​​the first air duct inlet to the area of ​​the second air duct inlet is e, and the ratio of the area of ​​the first air duct outlet to the area of ​​the second air duct outlet is k, where e > k.

[0147] When the regeneration fan 320 uses a centrifugal fan, the airflow blown out by the centrifugal fan is output along its impeller direction, which will cause the air volume on both sides of the air duct in the direction of rotation S to be different. The air volume on the side of the air duct facing the direction of rotation S is greater than the air volume on the other side. When the airflow passes through the heater and enters the moisture absorption and dehumidification component, the heat on the side of the moisture absorption and dehumidification component facing the direction of rotation S will be higher than that on the other side. This will lead to uneven heating of the moisture absorption and dehumidification component, reduce the dehumidification effect, and ultimately affect the drying effect of the drying module 10.

[0148] In this disclosure, the air duct is divided into two sub-air ducts with a first air duct inlet, a second air duct inlet, a first air duct outlet, and a second air duct outlet in the rotation direction of the centrifugal fan shaft by a guide member 330. The ratio of the area of ​​the first air duct inlet to the area of ​​the second air duct inlet is greater than the ratio of the area of ​​the first air duct outlet to the area of ​​the second air duct outlet. The area of ​​the air duct outlet 312 of the sub-air duct facing the rotation direction S is relatively increased, thereby improving the airflow uniformity of the air duct outlet 312 around the rotation direction S, making the air outlet of the air duct 312 more uniform, so that the heating of the moisture absorption and dehumidification component 230 is uniform, and the dehumidification effect is improved.

[0149] Specifically, the area of ​​the inlet of the first air duct can be made larger than the area of ​​the inlet of the second air duct, thereby increasing the air intake of the first air duct and improving the gas flow rate of the first air duct; when the area of ​​the inlet of the first air duct is larger than the area of ​​the inlet of the second air duct, the area of ​​the outlet of the first air duct can be made smaller than or equal to the area of ​​the outlet of the second air duct, thereby relatively reducing the area of ​​the outlet of the first air duct, so as to increase the gas flow rate of the outlet of the first air duct, thereby improving the uniformity of the airflow at the outlet of the air duct 312 around the rotation direction S.

[0150] Specifically, the area of ​​the first air duct outlet can be made smaller than the area of ​​the second air duct outlet, thereby relatively increasing the gas flow velocity at the first air duct outlet; when the area of ​​the first air duct outlet is smaller than the area of ​​the second air duct outlet, the area of ​​the first air duct inlet can be made greater than or equal to the area of ​​the second air duct inlet, so as to increase the air intake of the first air duct, increase the gas flow rate of the first air duct, and thus improve the uniformity of airflow at the air duct outlet 312 around the rotation direction S.

[0151] Alternatively, the area of ​​the first air duct inlet can be smaller than the area of ​​the second air duct inlet, and the area of ​​the first air duct outlet can be smaller than the area of ​​the second air duct outlet, so that the ratio e of the area of ​​the first air duct inlet to the area of ​​the second air duct inlet is greater than the ratio k of the area of ​​the first air duct outlet to the area of ​​the second air duct outlet.

[0152] like Figure 17 As shown, the guide member 330 can be flat. Using a flat guide member 330 can make the airflow in the duct more inclined to be horizontal, reduce the turbulent gas in the duct, and thus better achieve the homogenization of the airflow in the duct. Of course, the guide member 330 can also be curved or irregularly shaped, and this disclosure does not limit it.

[0153] It should be noted that the ratio e of the area of ​​the first air duct inlet to the area of ​​the second air duct inlet and the ratio k of the area of ​​the first air duct outlet to the area of ​​the second air duct outlet can be designed according to the actual size and shape of the air duct and the difference in the flow rate of the airflow provided by the centrifugal fan in the rotation direction S, as long as it can meet the requirement of achieving the effect of uniform airflow. This disclosure does not impose any restrictions on this.

[0154] In the direction from the air duct inlet 311 to the air duct outlet 312, the length of the guide member 330 can be the same as the length of the air duct, that is, the two ends of the guide member 330 are located on the air duct inlet 311 and the air duct outlet 312 respectively; of course, the length of the guide member 330 can also be less than the length of the air duct, with one end of the guide member 330 located on the air duct inlet 311 and the air duct outlet 312 respectively, and the other end located in the air duct, or both ends of the guide member 330 are located in the air duct.

[0155] like Figure 17As shown, the regeneration housing 310 includes an upper housing 3110 and a lower housing 3120 in the height direction, and the flow guide 330 is connected to the upper housing 3110 and / or the lower housing 3120.

[0156] In the vertical direction, the bottom end of the flow guide 330 is fixedly connected to the lower housing 3120, and the top end of the flow guide 330 is spaced apart from or abuts against the upper housing 3110; alternatively, the top end of the flow guide 330 is fixedly connected to the upper housing 3110, and the bottom end of the flow guide 330 is spaced apart from or abuts against the lower housing 3120; or alternatively, the top end of the flow guide 330 is fixedly connected to the upper housing 3110, and the bottom end of the flow guide 330 is fixedly connected to the lower housing 3120. When the top end of the flow guide 330 is fixedly connected to the upper housing 3110 and the bottom end of the flow guide 330 is fixedly connected to the lower housing 3120, the flow guide 330 can provide support for the upper housing 3110 and the lower housing 3120 to move closer together, thereby improving the structural strength of the regenerated housing 310.

[0157] The flow guide 330 can be fixedly connected to the regeneration shell 310 by means of plugging, bonding, welding, etc., or the flow guide 330 can also be integrated with the regeneration shell 310 by an integral molding process to form an integral structure.

[0158] In one embodiment, such as Figure 18 As shown, the regeneration module 300 further includes a support member 340, which is disposed in the air duct; at least one end of the support member 340 is connected to the regeneration housing 310 along the height direction of the regeneration housing 310. By providing the support member 340 in the air duct, the air duct can be supported, thereby improving the structural strength of the regeneration housing 310 and preventing deformation of the housing.

[0159] At least one end of the support member 340 is detachably connected to the regenerated housing 310. In the height direction, the bottom end of the support member 340 is fixedly connected to the lower housing 3120, and the top end of the support member 340 is spaced apart from or abuts against the upper housing 3110; alternatively, the top end of the support member 340 is fixedly connected to the upper housing 3110, and the bottom end of the support member 340 is spaced apart from or abuts against the lower housing 3120; furthermore, the top end of the support member 340 is fixedly connected to the upper housing 3110, and the bottom end of the support member 340 is fixedly connected to the lower housing 3120. When there is a gap between the top or bottom end of the support member 340 and the regenerated housing 310, the gap is relatively small, for example, less than 5 mm, so that the support member 340 can provide timely support in the event of slight deformation of the regenerated housing 310.

[0160] The support member 340 can be fixedly connected to the recycled shell 310 by means of threaded connection, bonding, welding, etc., or the support member 340 can also be integrated with the recycled shell 310 by an integral molding process to form an integral structure.

[0161] like Figure 11 As shown, in the direction from the air duct inlet 311 to the air duct outlet 312, the air duct includes a first guide section 3130 and a second guide section 3140. The extension direction of the first guide section 3130 intersects the extension direction of the second guide section 3140, and the support member 340 is supported at the position where the first guide section 3130 and the second guide section 3140 are connected.

[0162] Because the air inlet of the heating shell is fan-shaped, the air outlet 312 of the regeneration shell 310 needs to match the shape and size of the air inlet on the heating shell of the heating module 100. Therefore, the air outlet 312 and the air inlet 311 of the regeneration shell 310 have different shapes and sizes. By setting a first guide section 3130 and a second guide section 3140, the air inlet 311 is located on the first guide section 3130, and the air outlet 312 is located on the second guide section 3140. By setting the first guide section 3130 and the second guide section 3140, the air outlet 312 and the air inlet 311 of different shapes and sizes are satisfied, which can make the airflow in the airway tend to be laminar as much as possible and reduce turbulence, thereby facilitating the homogenization of the airflow in the airway. Among them, the first guide section 3130 can be rectangular, and the second guide section 3140 can be fan-shaped.

[0163] By supporting the support member 340 at the connection between the first guide section 3130 and the second guide section 3140, the strength of the regeneration shell 310 at the connection between the first guide section 3130 and the second guide section 3140 can be improved, and the influence of the support member 340 on the airflow in the channel can be reduced.

[0164] The regeneration module 300 may include multiple support members 340, which are spaced apart in the air duct. By spaced apart multiple support members 340, better support can be provided for the regeneration housing 310; for example, two, three or more support members 340 may be provided in the air duct, and this disclosure does not limit this.

[0165] When multiple support members 340 are provided, the support members 340 can be located at the connection between the first guide section 3130 and the second guide section 3140 in the regeneration shell 310, or at various locations in the regeneration shell 310. This disclosure does not limit this.

[0166] The support member 340 is columnar. By setting the support member 340 to a columnar shape, it can provide support for the regeneration housing 310 while reducing the impact of the support member 340 on the airflow in the duct.

[0167] The cross-section of the support member 340 along the direction perpendicular to its height can be circular, elliptical, teardrop-shaped, or similar to achieve low wind resistance. Of course, the cross-section of the support member 340 along the direction perpendicular to its height can also be rectangular, triangular, pentagonal, or irregular in shape; this disclosure does not impose any limitations on this.

[0168] In one embodiment, such as Figure 2 As shown, the drying module 10 is also connected to a circulation module 400, which includes a blower. The air inlet of the blower is connected to the air outlet of the clothes handling drum 20, and the air outlet of the blower is connected to the air inlet of the dehumidification module 200, for supplying the dehumidifying gas in the clothes handling drum 20 into the dehumidification module 200; or, 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 connected to the air outlet of the clothes handling drum 20, so that the blower creates a negative pressure in the dehumidification module 200 to introduce the dehumidifying gas in the clothes handling drum 20 into the dehumidification module 200.

[0169] After the dehumidifying gas is processed by the dehumidifying module 200, it becomes dry gas, which turns the wet circulating gas into dry circulating gas. The dry gas enters the clothes processing cylinder 20 through the air inlet and comes into contact with the clothes, thus achieving the purpose of circulating and dehumidifying the clothes in the clothes processing cylinder 20.

[0170] In one embodiment, such as Figure 2 As shown, the drying module 10 is also connected to a condensing module 500. The condensing module 500 can condense and dehydrate the humid and hot gas after it has undergone moisture removal by the moisture absorption and dehumidification component 230. The water vapor in the humid and hot gas is cooled to form condensate, which is discharged from the condenser and becomes dry and cold gas to be heated, which enters the regeneration fan 320 of the heating module 100, thus forming a closed-loop gas circulation. Of course, the dry and cold gas to be heated formed after the condenser treatment can also be directly discharged into the atmosphere, and this disclosure does not limit this. The condensing module 500 may include a tubular condenser, which cools the humid and hot gas so that the water vapor in the humid and hot gas is cooled to form condensate, which is discharged from the condenser. This disclosure does not limit the specific composition of the condensing module 500.

[0171] The gas supplied to the heating module 100 by the regeneration fan 320 can be dry and cold gas that has undergone moisture desorption by the moisture absorption and dehumidification component 230, i.e. gas recycling. The humidity of the supplied gas is relatively low, which can improve drying efficiency and reduce energy consumption; or, the regeneration fan 320 of the heating module 100 can also directly draw in gas from the outside.

[0172] In one embodiment, such as Figure 19As 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, in which at least a portion of the moisture absorption and dehumidification component 230 is received. One of the first dehumidification housing 210 and the second dehumidification housing 220 is provided with an air inlet, and the other is provided with an air outlet. The moisture absorption and dehumidification component 230 is configured to absorb moisture from the gas entering the receiving space. A hot air inlet is formed on the first dehumidification housing 210.

[0173] In one embodiment, the heating housing 110 and the dehumidifying housing are detachably connected by threaded connections. For example, the heating housing 110 of the heating module 100 has screw holes formed on it. When the heating housing 110 is integrally formed, the screw holes can be formed simultaneously as an assembly area for fixing the heating module 100 and the first dehumidifying housing 210, so that the heating module 100 and the first dehumidifying housing 210 can be directly connected together by screws, without the need to set other fixing screws on the heating housing 110 of the heating module 100.

[0174] The size, number, and distribution of the screw holes on the heating housing 110 can be set according to the specific structure of the heating housing 110 and the first dehumidifying housing 210, and this disclosure does not impose any restrictions on this.

[0175] In one embodiment, a first gas flow channel is provided between the first dehumidifying housing 210 and the moisture absorption and dehumidification component 230, and a second gas flow channel is also provided between the second dehumidifying housing 220 and the moisture absorption and dehumidification component 230. The first gas flow channel and the second gas flow channel form the dehumidification zone of the moisture absorption and dehumidification component 230. The humid gas in the clothes 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 channel; or, the humid gas in the clothes 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 channel.

[0176] The heating module 100's air outlet is connected to the hot air inlet on the first dehumidification housing 210, forming a third gas flow channel between the heater 140 and the moisture absorption and dehumidification component 230. A fourth gas flow channel is formed between the second dehumidification housing 220 and the moisture absorption and dehumidification component 230. This fourth gas flow channel is separated from the second gas flow channel by a barrier, thus separating the dehumidification zone from the dehydration zone. The heated, high-temperature dry gas enters the third gas flow channel to desorb moisture from the moisture absorption and dehumidification component 230. The humid gas after passing through the moisture absorption and dehumidification component 230 enters the fourth gas flow channel. During rotation, the various circumferential parts of the moisture absorption and dehumidification component 230 continuously pass through the dehumidification zone and the dehydration zone, thus continuously cyclically adsorbing and desorbing moisture, ultimately achieving the purpose of drying the clothes in the clothes treatment drum 20.

[0177] The dehumidification zone and the dehydration zone are relatively isolated so that the dehumidifying airflow in the first gas flow channel and the dehydrating airflow in the second gas flow channel and the dehydrating airflow in the third gas flow channel and the fourth gas flow channel are not interconnected, thus ensuring the dehydration effect on the humid gas.

[0178] Specifically, the moisture-absorbing and dehumidifying component 230 can be made of a material with good moisture absorption properties to improve its ability to adsorb moisture from humid gases, thereby enhancing the drying effect on underwear in the garment drying drum 20. Materials for the moisture-absorbing and dehumidifying component include, for example, lithium chloride, silica gel, zeolite, molecular sieves, etc., and this disclosure does not limit the types of materials used.

[0179] The moisture-absorbing and desiccant component 230 is equipped with a desiccant for absorbing moisture. The desiccant can be, for example, zeolite, modified / synthetic zeolite, molecular sieves (including but not limited to zeolite molecular sieves, A / X / Y type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), polymeric desiccant, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with moisture-absorbing properties. Among these, polymeric desiccant, also known as polymer adsorbent, has a lower regeneration temperature than traditional silica gel, activated carbon, and molecular sieve adsorbents.

[0180] The moisture-absorbing and desiccant component 230 can be made of porous materials such as zeolite, molecular sieve, metal-organic framework (MOF) materials, covalent organic frameworks (COFs), nano-carbon, and silica. In one embodiment, the moisture-absorbing and desiccant component 230 can also be formed by filling granular solids or particles made of at least one of the above-mentioned porous materials.

[0181] Among them, the moisture absorption and dehumidification component 230 can be a honeycomb or corrugated moisture absorption and dehumidification component carrying a desiccant, which can adsorb and desorb the absorbed water vapor to achieve repeated desorption and regeneration.

[0182] The moisture-absorbing and desiccant component 230 includes an inorganic / organic fiber carrier (such as ceramics, glass fiber, MOFs, COFs, cordierite, etc.). The fiber carrier is coated with a desiccant such as a molecular sieve, which is uniformly distributed between and on the surface of the fiber carrier to achieve adsorption of moisture from the airflow. The molecular sieve may include single-crystal or mixed-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, and Beta molecular sieves.

[0183] This disclosure does not restrict the specific materials of the moisture-absorbing and dehumidifying component 230. Any moisture-absorbing and dehumidifying component that can achieve the effect of moisture absorption and dehumidification is within the protection scope of this disclosure.

[0184] The drying module provided in this disclosure can be used in clothing processing equipment, such as washer-dryer combos; of course, the drying module provided in this disclosure can also be applied to household appliances that require moisture absorption / drying, such as refrigerators, air conditioners, and dishwashers.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
