[0002] With the improvement of living standards, many household appliances with drying functions have emerged to dry objects, providing great convenience for people's lives. 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.

[0052] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0053] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0054] The terms "a", "an", "the", "said" 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 express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0055] 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.

[0056] Specifically, the drying module 10 includes a heating module 100 , a dehumidification module 200 and a circulation module 300 .

[0057] like Figure 3 to Figure 8 As shown, the heating module 100 includes: a module shell, a heating component 130 and a fan 150. The module shell includes a first end 101 and a second end 102 opposite to each other. The first end 101 is formed with an air inlet 103, and the second end 102 is formed with an air outlet 104. An air duct connecting the air inlet 103 and the air outlet 104 is formed between the first end 101 and the second end 102. The heating component 130 is arranged in the air duct, and the fan 150 is connected to the air inlet 103 of the module shell.

[0058] Among them, a drain hole 160 is provided at the bottom of the module shell, and a one-way valve is provided on the drain hole 160, so that the liquid in the air duct can flow out of the drain hole 160 through the one-way valve. A one-way valve is a directional control valve that can only flow in one direction but not in the reverse direction. The one-way valve allows the fluid to flow only along the inlet of the drain hole 160 and cannot flow back through the outlet. Spring type: Use the power of the spring to push open the valve flap to prevent backflow. The one-way valve can be a passive one-way valve or an active one-way valve. The passive one-way valve relies on the external force of the medium to generate movement and complete closing and conduction by itself; the active one-way valve contains components such as an electromagnet / valve core spring, which can complete closing and conduction under active control. For example, a passive one-way valve can be a gravity one-way valve, which relies on the weight of the valve opening and closing part itself to prevent backflow.

[0059] The inventors discovered that in the module shell of the heating module 100, due to the volume limitation of the heating module 100, the height of the shell corresponding to the placement position of the heating module 100 is usually higher than the height of the position where the fan 150 is located, resulting in the module shell being high in the middle and low around. When there is residual moisture in the heating module 100, the moisture cannot be discharged in time, which can easily cause the heating module 100 to short-circuit, resulting in a malfunction.

[0060] The heating module 100 provided in the present disclosure has a drain hole 160 at the bottom of the module shell, and a one-way valve is provided on the drain hole 160. When there is residual moisture in the air duct, the moisture can flow out from the drain hole 160 through the one-way valve. Through the setting of the one-way valve, on the one hand, the residual moisture can flow out normally, and on the other hand, the gas outside the module shell is prevented from entering the module shell through the drain hole 160.

[0061] Among them, Figure 3 to Figure 7 As shown, in the second direction Y perpendicular to the first direction X pointing from the first end 101 to the second end 102, the height of the area in the air duct where the heating component 130 is provided is greater than the height of the area where the heating component 130 is not provided; the first direction X can be the length direction of the module shell, and the second direction Y is the height direction of the module shell.

[0062] At the position where the heating component 130 is set, by making the height of the area where the heating component 130 is set in the air duct greater than the height of the area where the heating component 130 is not set, when the fan 150 delivers cold air to the position where the heating component 130 is located, since the height of the air duct here is larger than the height of other areas, the air duct with a larger height is conducive to the airflow converging to the heating component 130 for a period of time and then entering the dehumidification module 200 through the air outlet 104, thereby improving the heating effect of the heating module 100 on the airflow, so that the heating temperature of the heated airflow is suitable for desorbing moisture from the moisture absorption and dehumidification component.

[0063] The module housing includes an upper housing 110 and a lower housing 120, which are buckled to form an air duct having an air inlet 103 and an air outlet 104. A protrusion 121 protruding toward the side away from the upper housing 110 is formed on the large surface of the lower housing 120, and the heating component 130 is located between the protrusion 121 of the lower housing 120 and the upper housing 110. The accommodating space of the heating component 130 is formed by the protrusion 121 of the lower housing 120, so that the heating component 130 can be installed in the air duct. Due to the sinking of the air flow, the air volume in the upper part of the air duct is less than the air volume in the lower part. Increasing the space in the lower part of the air duct where the heating component 130 is set can make the heat generated by the heating component 130 be more in the lower part close to the larger air volume, thereby improving the effect of heating the air flow.

[0064] like Figure 5 and Figure 6 As shown, a protruding structure that protrudes toward a side away from the lower shell 120 may also be provided on the upper shell 110 to cooperate with the protruding portion 121 on the lower shell 120 to form an enlarged air duct for accommodating the heating assembly 130.

[0065] Since a protrusion 121 is formed on the large surface of the lower shell 120 and protrudes toward the side away from the upper shell 110, the protrusion 121 of the lower shell 120 is lower than the surrounding area. When there is residual moisture in the heating module, the moisture cannot be discharged from the protrusion 121 in time, and the moisture accumulates in the protrusion 121. When too much moisture accumulates, it is easy to cause a short circuit in the heating component 130, causing malfunctions and safety hazards.

[0066] The drainage hole 160 may be formed on the protrusion 121 so that the liquid accumulated in the protrusion 121 can be drained smoothly.

[0067] like Figure 5 As shown, a drainage portion 161 extending toward the side away from the upper shell 110 is formed on the side of the protrusion 121 facing away from the upper shell 110, and a drainage hole 160 connected to the air duct is formed on the drainage portion 161. The liquid accumulated in the air duct is discharged through the drainage portion 161, thereby reducing the failure rate of the drying module 10 and improving the safety of the drying module 10.

[0068] The one-way valve provided on the drain hole 160 may be a ball valve. When liquid accumulates in the air duct, the liquid will provide buoyancy to the ball valve, so that the ball valve is in an open state, so that the accumulated liquid is discharged through the ball valve; after the liquid is discharged, the valve body of the ball valve loses buoyancy, so that the ball valve is in a closed state, that is, the gas outside the shell of the heating module 100 will not enter the air duct through the drain hole 160, thereby improving the accuracy of the heating component 130 heating the gas in the air duct.

[0069] like Fig. 9 As shown, a float 170 is provided in the drain portion 161, and the float 170 cooperates with the drain portion 161 to form a ball valve structure. The float 170 blocks the drain hole 160 by gravity; when the liquid in the air duct enters the drain portion 161, the float 170 can float to open the drain hole 160, so that the liquid can be discharged through the drain hole 160; after the liquid in the air duct is discharged, it is subjected to the downward pressure of the gas in the air duct, and the float 170 seals the drain hole 160, thereby preventing the external gas from entering the air duct through the drain hole 160.

[0070] The inner wall of the drainage portion 161 may be provided with a sealing inner wall matching the outer surface of the float 170, so that the outer surface of the float 170 and the inner wall of the drainage group can be in close contact to form a sealing abutment effect. For example, in the direction in which the lower shell 120 is away from the upper shell 110, at least part of the inner wall of the drainage hole 160 formed by the drainage portion 161 is a tapered conical surface, and the float 170 is located on the conical surface when sealing the drainage hole 160.

[0071] The heating module 100 further includes a limiting portion, which is arranged opposite to the liquid inlet of the drainage portion 161 , and is configured to limit the float 170 in the drainage portion 161 .

[0072] like Fig. 9 and Fig.10 As shown, the limiting portion includes a limiting rod 111 formed on the upper shell 110 and extending toward one side of the lower shell 120. The end of the limiting rod 111 is arranged opposite to the liquid inlet of the drainage portion 161 on the lower shell 120 to limit the float 170 in the drainage portion 161 to prevent the float 170 from falling out of the drainage hole 160, for example, during the installation or transportation of the heating module 100.

[0073] The limiting rod 111 and the upper shell 110 may be an integrated structure, for example, the upper shell 110 and the limiting rod 111 may be formed by a one-time injection molding process.

[0074] The limiting part may also include a perforated plate or a sealing net provided on the liquid inlet of the drainage part 161 on the lower shell 120, and the floating ball 170 is blocked by the perforated plate or the sealing net to form a limit. The present disclosure does not limit this, and any limiting part that limits the floating ball 170 from escaping belongs to the protection scope of the present disclosure.

[0075] The limiting portion may be a limiting rod 111, a perforated plate or a sealing net alone, or a combination of at least two of them, and the present disclosure does not impose any limitation on this.

[0076] Specifically, Fig.11 and Fig.12 As shown, the air duct of the heating module 100 includes a bottom wall, and the drainage hole 160 is located at the lowest position on the bottom wall of the air duct along the gravity direction, that is, located at the lowest position on the lower shell 120 along the gravity direction. By locating the drainage hole 160 at the lowest position on the bottom wall of the air duct along the gravity direction, the liquid can be discharged through the drainage hole 160 when flowing along the gravity direction, avoiding the situation where the drainage hole 160 is too high and part of the liquid cannot be discharged.

[0077] The height of each position on the bottom wall along the gravity direction gradually decreases in the direction close to the drain hole 160. By gradually decreasing the height of each position on the bottom wall of the lower shell 120 of the heating module 100 along the gravity direction, that is, there is no pit structure in the direction close to the drain hole 160, so that the liquid can flow to the drain hole 160 and flow out.

[0078] In one embodiment, Figure 5 and Figure 6As shown, the heating module 100 also includes an air uniforming member 140, which is arranged at the air outlet 104 of the air duct, or near the air outlet 104 of the air duct; the heated gas flows out through the guidance of the air uniforming member 140, and the air uniforming member 140 can make the heated gas flow out more evenly to enhance the dehumidification effect of the moisture absorption and dehumidification member.

[0079] In one embodiment, the heating component 130 may include a component housing and an electric heating element, the electric heating element includes a heating wire and a thermostat, the heating wire is arranged in the component housing, the component housing forms a heating air duct, the airflow input by the fan 150 is heated through the heating air duct; the thermostat is connected to the heating wire, the thermostat is used to monitor the heat value generated by the heating wire, and can control the heating value of the heating wire according to the heat value, so that the heating wire heats the gas input by the fan 150 to a preset temperature output.

[0080] The thermostat can be arranged in the accommodation space of the component housing to obtain the heat value generated by the heating wire more accurately. Of course, the thermostat can also be arranged outside the component housing, and a connection hole is provided on the component housing to connect the thermostat to the heating wire.

[0081] In one embodiment, the thermostat may also be a fuse, a fuse piece or a similar fuse, which is used to disconnect the heating when the temperature reaches a preset temperature value to protect the heater.

[0082] like Figure 1 and Figure 2 As shown, the drying module 10 includes: a dehumidification module 200 and a heating module 100 provided in the above embodiment. Fig.15 As shown, the dehumidification module 200 includes a dehumidification housing and a moisture absorption and dehumidification member 230. The dehumidification housing is formed with a receiving space having an air suction port and an air discharge port. At least a portion of the moisture absorption and dehumidification member 230 is disposed in the receiving space. The moisture absorption and dehumidification member 230 is configured to absorb moisture in the gas entering the receiving space. At least a portion of the moisture absorption and dehumidification member 230 is disposed opposite to the air outlet on the housing of the heating module 100. The heating module 100 is configured to dehydrate the portion of the moisture absorption and dehumidification member 230 located at the air outlet. The moisture absorption and dehumidification member 230 may be a rotating disk, and gear teeth may be disposed on the edge of the rotating disk so as to mesh with the gear teeth of the rotating disk through the gear connected to the output shaft of the motor, thereby driving the rotating disk to rotate.

[0083] Specifically, the exhaust port of the dehumidification module 200 is connected to the air inlet of the clothing treatment drum 20, and the air intake port of the dehumidification module 200 is connected to the air outlet of the clothing treatment drum 20, so as to continuously adsorb the moisture in the gas in the clothing treatment drum 20 through the dehumidification module 200; the heating module 100 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 230 in the dehumidification module 200 to dehumidify and dehydrate the moisture absorption and dehumidification component 230, so that the moisture absorption and dehumidification component 230 has the ability to absorb moisture again; during the rotation of the moisture absorption and dehumidification component 230, 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 of the clothes in the clothing treatment drum 20. Among them, Figure 5 As shown, the moisture absorption and dehumidification member 230 may be a rotating disk with meshing teeth on the edge thereof, and may pass through the dehumidification zone of the dehumidification module 200 and the dehydration zone of the heating module 100 by rotating.

[0084] Among them, Fig.15 As shown, the dehumidification shell includes a first dehumidification shell 210 and a second dehumidification shell 220. 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 moisture absorption and dehumidification component 230 is contained; the first dehumidification shell 210 and the second dehumidification shell 220 are respectively provided with ventilation holes to serve as air intake and air exhaust; wherein, a heating air hole is formed on the first dehumidification shell 210.

[0085] Among them, fan-shaped heating air holes are formed on the first dehumidification shell 210, and the heating module 100 is installed on the fan-shaped heating air holes. The heating module 100 is located above the moisture absorption and dehumidification component 230. Through the fan-shaped heating air holes, there is a larger heating area between the heating module 100 and the moisture absorption and dehumidification component 230.

[0086] Specifically, there is a first gas flow channel between the first dehumidification shell 210 and the moisture absorption and dehumidification component 230, and there is also a second gas flow channel 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.

[0087] Among them, the air outlet of the heating module 100 is connected to the heating air hole on the first dehumidification shell 210, that is, a third gas flow channel is formed between the heating module 100 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.

[0088] 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.

[0089] In one embodiment, the heating module 100 also includes a heat-resistant component, which is arranged at the air outlet 104 of the module shell, located on the side of the air outlet 104 close to the heating component 130, and the heat-resistant component is located between the module shell and the dehumidification shell, and is arranged opposite to the edge area of ​​the moisture absorption and dehumidification component 230.

[0090] There may be a gap between the lower shell 120 and the first dehumidification shell 210. When the moisture absorption and dehumidification component 230 does not rotate and the heating component is still turned on in an abnormal state, heat can be easily transferred to the first dehumidification shell 210 through the gap, resulting in the risk of the first dehumidification shell 210 being melted by heat.

[0091] The present invention prevents heat from being transferred to the first dehumidification shell 210 at the gap by setting a heat-blocking component in the gap, and protects the first dehumidification shell 210 outside the dehumidification component 230 from being melted by heat in an abnormal state where the dehumidification component 230 does not turn but the heating component is still turned on.

[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 230 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 may be 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. Among them, 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 component 230 may be a honeycomb or corrugated moisture absorption and dehumidification component 230 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 may include 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 230 that can achieve the moisture absorption and dehumidification effect belongs to the protection scope of the present disclosure.

[0098] like Figure 1 and Figure 2 As shown, the drying module 10 is also provided with a circulation module 300, 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 feed the gas to be dehumidified in the clothing treatment drum 20 into the dehumidification module 200; the gas to be dehumidified is formed into dry gas after being processed by the dehumidification module 200, so that the wet circulating gas is converted into dry circulating gas, and the dry gas enters the clothing treatment drum 20 through the air inlet of the clothing treatment drum 20 and contacts the clothes, thereby achieving the purpose of circulating dehumidification of the clothes in the clothing treatment drum 20.

[0099] like Figure 1 and Figure 2 As shown, the drying module 10 is also provided with a condensation module 400, 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, which is discharged from the condenser and becomes dry and cold gas to be heated. It enters the fan 150 of the heating module 100, and 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 400 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, which is discharged from the condenser; the present disclosure does not limit the specific composition of the condensation module.

[0100] Among them, the gas delivered to the heating module 100 through the fan 150 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 fan 150 of the heating module 100 can also directly inhale gas from the outside.

[0101] like Fig.13 and Fig.14 As shown, a drain port is provided on the condensing shell 410, and the drain hole 160 on the module shell is connected to the condensing cavity 430 of the condensing shell 410, so as to discharge the liquid flowing out of the drain hole 160 of the heating module 100 through the drain port of the condensing shell 410, that is, the drain port of the condensing shell 410 is shared, thereby avoiding the need to set up an additional separate drainage pipeline for the drain hole 160 of the heating module 100, thereby improving the integration of the drying module 10 and reducing the manufacturing cost of the drying module 10.

[0102] Among them, a through hole can be set on the condensing shell 410, and then the drainage part 161 on the heating module 100 is extended into the condensing shell 410 through the through hole; or, the drainage hole 160 on the heating module 100 and the through hole on the condensing shell 410 can be connected by a pipeline.

[0103] Among them, after the drainage portion 161 on the heating module 100 enters the condensation shell 410 through the through hole, the through hole and the condenser 420 are staggered to prevent liquid from dripping on the condenser 420 and affecting the condensation effect of the condenser 420.

[0104] Among them, Figure 13 to Figure 15As shown, the condensation shell 410 can be an integrated shell with the shell of the dehumidification module 200, that is, the upper shell of the condensation shell 410 and the first dehumidification shell 210 of the dehumidification module 200 are an integrated shell, and the lower shell of the condensation shell 410 and the second dehumidification shell 220 of the dehumidification module 200 are an integrated shell; of course, the condensation shell 410 and the shell of the dehumidification module 200 can be independent split shells, and the present disclosure does not limit this.
