Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electrical appliances, and particularly relates to a drying device and a clothes processing device. BACKGROUND

[0002] In the related art, the drying efficiency of clothes processing devices such as clothes dryers or drying all-in-one machines has room for improvement. SUMMARY

[0003] The present application provides a drying device and a clothes processing device, aiming to at least partly improve the drying efficiency of the clothes processing device.

[0004] In a first aspect of the present application, a drying device is provided, comprising a moisture absorption and removal module, a heat pump module heating assembly, and a cooler, wherein the moisture absorption and removal module has a desiccation zone and a desorption zone separated by a partition, the heat pump module comprises an evaporator and a condenser, and along the airflow direction, the evaporator, the desiccation zone of the moisture absorption and removal module, and the condenser are sequentially connected, and the desorption zone of the moisture absorption and removal module, the cooler, and the heating assembly are sequentially and circularly connected.

[0005] When the drying device provided by the present application is applied to a clothes processing device, the moisture introduced from the air outlet of the drum of the device flows through the evaporator to release part of the water, and is then adsorbed onto the rotating disc of the moisture absorption and removal module. When the rotating disc rotates to the desiccation zone, the rotating disc further releases the water in the moisture flow, forming a low-temperature dry gas flow. After the low-temperature dry gas flow is heat-exchanged by the condenser, a high-temperature dry gas flow is generated to dry the clothes. Since the moisture has passed through the adsorption of the desiccation zone of the moisture absorption and removal module, the water content of the dry gas flow is reduced, and the drying efficiency of the clothes processing device is effectively improved, and the drying time is reduced. The water released by the moisture absorption and removal module is stored in the desorption zone of the moisture absorption and removal module, and is released under the action of the heating assembly to generate a moisture flow. The moisture flow is condensed into condensate water by the cooler to form a medium-temperature high-humidity gas flow. The medium-temperature high-humidity gas flow is heated by the heating assembly to become a high-temperature dry gas flow. The high-temperature dry gas flow enters the desorption zone of the moisture absorption and removal module to remove the water stored in the desorption zone of the moisture absorption and removal module, and again forms a moisture flow. The moisture flow enters the cooler again to release condensate water, thereby generating a medium-temperature high-humidity gas again. This cycle is repeated to improve the drying efficiency of the clothes processing device.

[0006] In some embodiments, a compressor and a throttling component are further included, and along the refrigerant flow direction, the compressor, the condenser, the throttling component, the evaporator, and the cooler are sequentially and circularly connected.

[0007] In some embodiments, a compressor and a throttling component are further included, and along the refrigerant flow direction, the compressor, the condenser, the throttling component, the cooler, and the evaporator are sequentially and circularly connected.

[0047] In order for those skilled in the art to which the present application pertains to more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0048] In recent years, with the continuous enhancement of people's pursuit of life experience consciousness, clothes processing equipment such as clothes dryers and washing and drying integrated machines gradually receives the favor of consumers in various regions due to its unique functionality. At present, the dry mode is mainly divided into condensing type, exhaust type and heat pump type. Compared with the other two drying methods, the heat pump type drying mode can reduce the damage to clothes, improve the fluffiness of clothes, and can recover the latent heat and sensible heat of air flow, has low energy consumption, and is deeply loved by the public.

[0049] Figure 1 And Figure 2 The structure schematic diagram of the clothes processing equipment according to an embodiment of the present application is shown. In combination with Figure 1 And Figure 2 The clothes processing equipment of the clothes dryer or the washing and drying integrated machine can include a shell 1, a door body 2, a drum 3 and a drying device 4. The front side of the shell 1 is provided with a feeding port 101, which is used for the user to put clothes into the drum 3 or take clothes out of the drum 3. The door body 2 is rotatably connected to the front side of the shell 1 to open and close the feeding port 101. The drum 3 is rotatably installed inside the shell 1 to accommodate clothes.

[0050] As shown in 1 and Figure 2As shown, in an embodiment of the present application, the air inlet 102 of the air inlet channel is arranged below the drop opening 101, the air outlet channel 103 is arranged below the drum 3, and the air inlet channel 104 is arranged at the back of the drum 3. The drum 3, the air outlet channel 103, and the air inlet channel 104 are sequentially communicated to form an air duct for air circulation. The air outlet channel 103 is provided with a drying device 4. The wet air discharged from the drum 3 enters the air outlet channel 103 from the air inlet 102 and is dried by the drying device 4 to form clean dry air flow. The air inlet channel 104 introduces the dry air flow into the drum 3 to dry the clothes in the drum 3.

[0051] It should be noted that, Figure 1 and Figure 2 The layout method of the drying device 4, the air outlet channel 103, the air inlet 102 of the air outlet channel 103, and the air inlet channel 104 in the clothes treatment equipment is only an example for the reader to understand, and does not limit the positions and relative relationships of these devices / components. For example, in another embodiment of the present application, the drying device 4 is arranged above the drum 3, or drying devices 4 are arranged above and below the drum 3 to process the wet air flow from the drum 3 into dry air flow, respectively. Correspondingly, the air outlet channel 103 or the air inlet channel 104 can be arranged above, below, or behind the drum 3. Due to the large number of examples, they are not listed one by one here.

[0052] In the related art, the drying device of the clothes treatment equipment in the heat pump drying mode includes an evaporator, a condenser, and an air guide fan arranged along the air flow direction. The evaporator and the condenser constitute a heat pump module. Under the action of the air guide fan, the wet air flow in the drum passes through the evaporator, is cooled and dehydrated, is heated by the condenser, and forms dry air flow. The dry air flow flows into the drum to dry the clothes in the drum. In the related art, the clothes treatment equipment has the technical problem of long drying time during drying, which affects the drying efficiency of the clothes treatment equipment.

[0053] The reason is that during the operation of the clothes treatment equipment, the wet air flow in the drum still contains a lot of water after being cooled and dehydrated by the evaporator. After the air flow containing water is heated by the condenser, the high-temperature air flow generated still contains too much water. The high-temperature air flow containing too much water is guided into the drum to dry the clothes, which affects the drying efficiency of the clothes in the drum, and then causes the drying time to be longer.

[0054] Based on the above technical problems, the present application provides a drying device and a clothes treatment equipment, which aims to at least improve the drying efficiency of the clothes treatment equipment.

[0055] The design idea of the present application is that: by adding a moisture adsorption and removal module before the high-temperature airflow is introduced into the cylinder, on the one hand, the moisture adsorption and removal module can adsorb the moisture in the low-temperature airflow, reduce the moisture in the high-temperature airflow introduced into the cylinder, improve the dryness degree of the high-temperature airflow, and then improve the drying efficiency of the clothes in the cylinder and reduce the drying time; on the other hand, the moisture adsorption and removal module can also release the adsorbed moisture under the action of the heating assembly to generate a humid airflow, which is used again to improve the drying efficiency of the clothes treatment equipment.

[0056] The specific technical solutions will be described in detail with reference to the drawings, which are not necessarily drawn to scale. Similar or identical reference numerals can be used to designate similar or identical parts in different drawings. The use of similar or identical reference numerals in different drawings does not mean that all drawings comprising similar or identical reference numerals constitute a single or same embodiment. The drawings generally illustrate various embodiments discussed in the present application in an exemplary and non-limiting manner.

[0057] Based on the above design idea, in a first aspect of the present application, a moisture adsorption and removal module is provided, which is part of a drying device. Figure 3 A structural schematic diagram of the moisture adsorption and removal module in one or more embodiments of the present application is shown, Figure 4 a structural schematic diagram of another view of Figure 3 is shown. In combination with Figure 3 and Figure 4 , the moisture adsorption and removal module comprises a regeneration housing 411 and a wheel disc 412. Figure 5 A structural schematic diagram of the regeneration housing 411 in Figure 3 is shown, Figure 6 a structural schematic diagram of another view of Figure 5 is shown, in combination with Figure 5 and Figure 6 , the regeneration housing 411 is provided with a containing cavity 4111, the containing cavity 4111 is provided with a moisture removal zone 4112 and a desorption zone 4113 in a spaced manner, and the wheel disc 412 is rotatably arranged in the containing cavity 4111, wherein when the wheel disc 412 rotates to the moisture removal zone 4112, the wheel disc 412 adsorbs the moisture in the humid airflow; when the wheel disc 412 rotates to the desorption zone 4113, the moisture adsorbed by the wheel disc 412 is released under the action of the heating assembly 44.

[0058] When the moisture absorption and dehumidification module is applied to the drying device, the moisture from the air outlet of the drying device passes through the evaporator 5 to release part of the water, and is then adsorbed to the wheel disc 412 of the moisture absorption and dehumidification module. When the wheel disc 412 rotates to the dehumidification area 4112, the wheel disc 412 further releases the water in the moisture flow to form a low-temperature dry gas flow. The low-temperature dry gas flow is then heated by the condenser 6 to generate a high-temperature dry gas flow to dry the clothes. Since the moisture is adsorbed by the dehumidification area 4112 of the wheel disc 412, the water content of the dry gas flow is reduced, and the drying efficiency of the clothes treatment device is effectively improved, and the drying time is reduced. When the wheel disc 412 rotates to the desorption area 4113, the water adsorbed by the wheel disc 412 is released under the action of the heating assembly 44 to generate a moisture flow. The moisture flow is then adsorbed by the evaporator 5 and the wheel disc 412, and heated by the condenser 6 to generate a high-temperature dry gas flow for reuse, thereby improving the drying efficiency of the clothes treatment device. The specific details of the moisture absorption and dehumidification module will be further described with reference to the accompanying drawings.

[0059] In combination Figure 5 and Figure 6 According to an embodiment of the present application, the moisture absorption and dehumidification module further comprises a partition 4114, both ends of the partition 4114 are connected to the inner wall of the accommodating cavity 4111, and the middle part of the partition 4114 extends to the middle part of the accommodating cavity 4111. The partition 4114 divides the accommodating cavity 4111 into the dehumidification area 4112 and the desorption area 4113.

[0060] In combination Figure 5 and Figure 6 According to an embodiment of the present application, the partition 4114 is also substantially U-shaped. The inner wall of the partition 4114 and the inner wall of the accommodating cavity 4111 form the desorption area 4113, and the outer wall of the partition 4114 and the inner wall of the accommodating cavity 4111 form the dehumidification area 4112. That is, the accommodating cavity 4111 is divided into the dehumidification area 4112 and the desorption area 4113 by the partition 4114. The volume of the desorption area 4113 is smaller, and the volume of the dehumidification area 4112 is larger. The dehumidification area 4112 is used as the main gas flow path, and the desorption area 4113 is used as the auxiliary gas flow path. The volume of the desorption area 4113 is about one-third of the volume of the dehumidification area 4112, so as to ensure the gas flow of the main gas flow path, and then ensure the gas flow of the clothes in the drying cylinder 3, and protect the drying effect of the clothes in the drying cylinder 3.

[0061] In combination Figure 3The moisture absorption and removal module further comprises a driving member 42 connected with the wheel disc 412 to drive the rotation of the wheel disc 412 in the accommodating cavity 4111. That is, under the action of the driving member 42, the wheel disc 412 and the supporting member 414 rotate synchronously in the accommodating cavity 4111. When the wheel disc 412 rotates to the desorption area 4113, the water absorbed by the wheel disc 412 is separated under the action of the heating assembly 44.

[0062] In combination with Figure 3 and Figure 4 According to an embodiment of the present application, the moisture absorption and removal module further comprises an air guide cover 43 connected with the desorption area 4113. The air guide cover 43 can guide the moisture flow with temperature to a suitable position to reuse the moisture flow with temperature, thereby improving the drying efficiency.

[0063] Figure 7 A structure diagram of the heating assembly 44 in Figure 2 is shown. In combination with Figure 7 According to an embodiment of the present application, the heating assembly 44 is connected upstream of the desorption area 4113. When the wheel disc 412 rotates to the desorption area 4113, the water absorbed by the wheel disc 412 is separated under the action of the heating assembly 44. The heating assembly 44 comprises a heating shell 441, a heating member 442 and a first air guide member 443. The heating shell 441 is connected with the air guide opening of the desorption area 4113. The heating member 442 and the first air guide member 443 are arranged in the heating shell 441. The first air guide member 443 sucks the air outside and generates high-temperature air after being heated by the heating member 442. When the wheel disc 412 rotates to the desorption area 4112, the high-temperature air separates the water absorbed by the wheel disc 412 to form a moisture flow with temperature, which is guided out of the air return opening of the desorption area 4112.

[0064] In combination with Figure 7 In an embodiment, the first air guide member 443 and the heating member 442 are sequentially close to the desorption area 4113. The first air guide member 443 can be a fan. The shell of the fan extends to the air guide opening of the desorption area 4113. The heating member 442 can be a disc structure arranged in the heating shell 441 between the impeller of the fan and the air guide opening. In another embodiment, the heating member 442 and the first air guide member 443 are close to the air guide opening. The present application does not limit this.

[0065] Based on the same design idea, in a second aspect of the present application, the present application further provides a drying device 4. Figure 8 A schematic diagram of air flow of a clothes treatment apparatus in one or more embodiments of the present application is shown. In combination with Figure 8In an embodiment, the drying device 4 comprises a heat pump module, the cooler 7, the above-mentioned moisture absorption and desorption module 41 and the heating assembly 44, the heat pump module comprises the evaporator 5 and the condenser 6, in the air flow direction, the evaporator 5, the dehumidification zone 4112 of the moisture absorption and desorption module 41 and the condenser 6 are sequentially connected, and the desorption zone 4113 of the moisture absorption and desorption module 41, the cooler 7 and the heating assembly 44 are sequentially and circularly connected.

[0066] When the drying device 4 provided by the application is applied to the laundry treatment equipment, the moisture introduced from the air outlet of the drum 3 of the equipment passes through the evaporator 5 to release part of the water, and is then adsorbed to the wheel disc 412 of the moisture absorption and desorption module 41. When the wheel disc 412 rotates to the dehumidification zone 4112, the wheel disc 412 further releases the water in the moisture flow, forming a low-temperature dry gas flow. After heat exchange of the low-temperature dry gas flow in the condenser 6, a high-temperature dry gas flow is generated, which is introduced into the drum 3 to dry the laundry. Since the moisture is adsorbed by the dehumidification zone 4112 of the moisture absorption and desorption module 41, the water content of the dry gas flow is reduced, and the drying efficiency of the laundry treatment equipment is effectively improved, and the drying time is reduced. The water adsorbed by the moisture absorption and desorption module 41 is stored in the desorption zone 4113 of the moisture absorption and desorption module 41, and is released under the action of the heating assembly 44 to generate a moisture flow. The moisture flow passes through the cooler 7 to release condensed water, forming a medium-temperature and high-humidity gas flow. The medium-temperature and high-humidity gas flow is heated by the heating assembly 44 to become a high-temperature dry gas flow, which enters the desorption zone 4113 of the moisture absorption and desorption module 41 to take away the water stored in the desorption zone 4113 of the moisture absorption and desorption module 41, and then forms a moisture flow again. The moisture flow enters the cooler 7 again to release condensed water, thereby generating a medium-temperature and high-humidity gas again. Such a cycle is repeated to further improve the drying efficiency of the laundry treatment equipment.

[0067] It should be noted that the evaporator 5, the dehumidification zone 4112 of the moisture absorption and desorption module 41 and the condenser 6 can be arranged in the same air duct, and the desorption zone 4113 of the moisture absorption and desorption module 41, the cooler 7 and the heating assembly 44 can be arranged in another air duct to ensure that the air flow flows in the preset direction. In addition, the desorption zone 4113 of the moisture absorption and desorption module 41, the cooler 7 and the heating assembly 44 are sequentially and circularly connected, which means that the desorption zone 4113 of the moisture absorption and desorption module 41 is connected with the cooler 7 and the heating assembly 44 respectively, and the cooler 7 is connected with the heating assembly 44 to form an air flow circulation.

[0068] In combination with Figure 8The drying device further comprises a compressor 8 and a throttling component 9, and the compressor 8, the condenser 6, the throttling component 9, the evaporator 5 and the cooler 7 are sequentially and circularly connected in the direction of refrigerant flow. In a specific implementation, the high-temperature and high-pressure gaseous refrigerant is changed into high-pressure and medium-temperature liquid refrigerant after releasing heat in the condenser 6, the high-pressure and medium-temperature liquid refrigerant is changed into low-temperature and low-pressure gaseous-liquid two-phase refrigerant after being cooled and decompressed by the throttling component 9, the low-temperature and low-pressure gaseous-liquid two-phase refrigerant is heated in the evaporator 5 and then is continuously heated in the cooler 7, and finally the refrigerant is compressed into high-temperature and high-pressure gaseous refrigerant by the compressor 8, and the cycle is repeated.

[0069] It should be noted that the compressor 8, the condenser 6, the throttling component 9, the evaporator 5 and the cooler 7 are sequentially and circularly connected in the direction of refrigerant flow, which means that the output of the compressor 8, the condenser 6, the throttling component 9, the evaporator 5 and the cooler 7 are sequentially connected in the direction of refrigerant flow, and the cooler 7 is connected to the input of the compressor 8 to form a refrigerant loop.

[0070] Figure 9 The air flow schematic diagram of the laundry treating apparatus in another embodiment is shown in Figure 9 , Figure 9 The main difference between the laundry treating apparatus shown in Figure 8 and the laundry treating apparatus shown in is the sequence of the refrigerant entering the evaporator 5 and the condenser 6 after passing through the throttling component 9, and the rest can be referred to the related description of the above laundry treating apparatus, specifically, the compressor 8, the condenser 6, the throttling component 9, the cooler 7 and the evaporator 5 are sequentially and circularly connected in the direction of refrigerant flow. The high-temperature and high-pressure gaseous refrigerant is changed into high-pressure and medium-temperature liquid refrigerant after releasing heat in the condenser 6, the high-pressure and medium-temperature liquid refrigerant is changed into low-temperature and low-pressure gaseous-liquid two-phase refrigerant after being cooled and decompressed by the throttling component 9, the low-temperature and low-pressure gaseous-liquid two-phase refrigerant is heated in the cooler 7 and then is continuously heated in the evaporator 5, and finally the refrigerant is compressed into high-temperature and high-pressure gaseous refrigerant by the compressor 8, and the cycle is repeated.

[0071] It should be noted that the compressor 8, the condenser 6, the throttling component 9, the cooler 7 and the evaporator 5 are sequentially and circularly connected in the direction of refrigerant flow, which means that the output of the compressor 8, the condenser 6, the throttling component 9, the cooler 7 and the evaporator 5 are sequentially connected in the direction of refrigerant flow, and the evaporator 5 is connected to the input of the compressor 8 to form a refrigerant loop.

[0072] Figure 8 In the laundry treating apparatus shown in Figure 9 , the refrigerant is mainly used for dehumidification in the evaporator 5; In the laundry treating apparatus shown in Figure 8 , the refrigerant is mainly used for dehumidification in the cooler 7, which can be adaptively selected according to the temperature requirement of the drum 3, and the present application does not limit this. In addition, according to an embodiment of the present application, Figure 9The liquid water condensed on the surface of the evaporator 5 and the liquid water condensed on the surface of the cooler 7 in the clothes treatment apparatus shown can be directly discharged by the drain pump or stored in the water box, which is not limited in the present application.

[0073] Figure 10 The air flow schematic diagram of the clothes treatment apparatus in the third embodiment of the present application is shown, which is combined with Figure 10 , Figure 10 The main difference between the clothes treatment apparatus shown and the clothes treatment apparatus shown above is that the refrigerant can be controlled to enter at least one of the evaporator 5 and the condenser 6 of the heat pump module after passing through the throttling component 9, so that the clothes treatment apparatus can have different dehumidification modes, that is, at least one of the heat pump dehumidification and the dehumidification module dehumidification is performed, and the rest can be referred to the related description of the clothes treatment apparatus above.

The output of the compressor 8 outputs high-temperature and high-pressure gaseous refrigerant, which becomes high-pressure and medium-temperature liquid refrigerant after releasing heat through the condenser 6, and the high-pressure and medium-temperature liquid refrigerant is cooled and decompressed to low-temperature and low-pressure gas-liquid two-phase refrigerant through the throttling component 9. The low-temperature and low-pressure gas-liquid two-phase refrigerant absorbs heat after entering at least one of the evaporator 5 and the cooler 7, and then enters the compressor 8 to be compressed into high-temperature and high-pressure gaseous refrigerant, which is circulated repeatedly. For the refrigerant that can be controlled to enter at least one of the evaporator 5 and the condenser 6 after passing through the throttling component 9, so that the clothes treatment apparatus can have different dehumidification modes, the related description of the control method below can be referred to.

In this way, part of the refrigerant conveying pipeline can be saved. In another embodiment, the first valve body 12 and the second valve body 13 can also be connected with the throttling component 9 through corresponding refrigerant pipelines, which is not limited in the present application.

[0082] In the fourth aspect of the present application, the present application further provides a control method of the laundry treating apparatus shown in embodiment three. Figure 11 A flowchart of the control method of the laundry treating apparatus of the present application is shown in conjunction with Figure 11 The control method comprises:

[0083] S1: obtaining the real-time temperature in the cylinder and comparing the real-time temperature with the set temperature, the real-time temperature in the cylinder can be obtained by the temperature sensor arranged in the cylinder;

[0084] S2: when the real-time temperature is less than the set temperature, the throttling component 9 is connected with the cooler 7 and the evaporator 5, i.e. the first valve body 12 and the second valve body 13 are opened, the laundry treating apparatus executes the heat pump dehumidification and the dehumidification module 41, the heat pump system composed of the evaporator 5 and the condenser 6 and the dehumidification module 41 work simultaneously, which can efficiently increase the temperature in the cylinder, avoid the temperature preheating time in the initial stage, shorten the drying time and improve the drying efficiency;

[0085] S3: when the real-time temperature is greater than or equal to the set temperature, the drying opportunity of the laundry treating apparatus is confirmed;

[0086] S31: when the laundry treating apparatus is in the early stage of drying, the throttling component 9 is connected with the evaporator 5 and the throttling component 9 is disconnected with the cooler 7, i.e. the first valve body 12 is opened and the second valve body 13 is closed, the laundry treating apparatus executes the heat pump dehumidification, which can work through the heat pump system with stronger dehumidification capacity to ensure the temperature in the cylinder to rise rapidly to improve the drying efficiency;

[0087] S32: when the laundry treating apparatus is in the late stage of drying, the throttling component 9 is connected with the cooler 7 and the throttling component 9 is disconnected with the evaporator 5, the laundry treating apparatus executes the dehumidification of the dehumidification module 41, i.e. the first valve body 12 is closed and the second valve body 13 is opened, the laundry treating apparatus executes the dehumidification of the dehumidification module 41, since the air humidity is small, the dehumidification capacity of the heat pump system is weak, therefore, the dehumidification of the dehumidification module 41 is ensured to guarantee the temperature in the cylinder and the drying efficiency.

[0088] The control method of the laundry treating apparatus provided by the present application can control the on-off of the valve body to make the laundry treating apparatus in different dehumidification modes to adapt to different cylinder temperatures, guarantee the temperature in the cylinder and improve the drying efficiency.
