Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing machines, and in particular to a heat exchange component and a clothing processing device. Background Art

[0002] Currently, after washing is completed, a washing machine needs to introduce hot air into the washing drum to dry the clothes.

[0003] In the related art, in order to reduce energy waste, hot air needs to be recycled, and an air outlet is usually set on the upper side of the barrel. The hot air enters the drying tunnel from the air outlet for heating and then enters the barrel again. In order to prevent the lint in the barrel from being brought into the drying tunnel, a filter and a filter flushing structure are set at the air outlet. The filter flushing structure usually uses a spray pipe, but the spray pipe is not only complicated to install, but also sprays uneven water. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention provides a heat exchange component.

[0006] A second aspect of the present invention provides a clothes treating device.

[0007] In view of this, the first aspect of the present invention provides a heat exchange component, including a shell, an air duct, a flow channel and a plurality of spray holes; the air duct is arranged in the shell; the flow channel is arranged on the shell; a plurality of spray holes are arranged on the shell, connected with the flow channel, and arranged toward the air duct.

[0008] The heat exchange component provided by the present invention is provided with a flow channel and a spray hole on the shell, and the flow channel is connected with the spray hole. After the liquid enters the flow channel, it can be sprayed out from the spray hole and sprayed into the air duct or onto the filter element, thereby flushing the hair debris in the air duct or on the filter element, avoiding the accumulation of hair debris in the air duct or on the filter element, and ensuring that the hair debris in the air duct or on the filter element will not circulate into the inner drum of the clothing processing device with the hot air.

[0009] In addition, the flow channel and the spray hole are arranged on the shell, and no additional spray pipe is required in the air duct, which simplifies the structure and production process of the heat exchange component. The spray hole is arranged on the shell, so that the liquid sprayed from the spray hole is more uniform, which improves the flushing effect on the air duct and the filter.

[0010] When drying clothes, the hot air flowing out of the clothes processing device enters the air duct and exchanges heat with the liquid sprayed from the spray hole in the air duct. After the heat exchange, the temperature of the hot air flowing out of the clothes processing device decreases, so that the high-temperature water vapor contained in the hot air condenses into liquid water, thereby reducing the moisture content in the hot air, making the hot air flowing back into the clothes processing device drier, thereby improving the drying effect of the clothes.

[0011] Since the drying effect of clothes is improved, clothes can be dried more quickly, thereby improving the drying efficiency of the clothes processing device and shortening the time required for clothes drying. In addition, the energy loss in the process of drying clothes can be reduced, thereby reducing the cost required for clothes processing devices to dry clothes and improving the quality of clothes processing devices. In addition, the heat exchange component in the above technical solution provided by the present invention can also have the following additional technical features:

[0012] In a technical solution of the present invention, the heat exchange assembly is used in a clothes processing device, which includes an inner drum, and a through hole is arranged on the inner drum; the positions of the plurality of spray holes are staggered with the positions of the through holes.

[0013] In this technical solution, the positions of the multiple spray holes are staggered with the positions of the through holes, so as to prevent the liquid sprayed from the spray holes from entering the inner drum through the through holes and wetting the clothes in the inner drum, thereby improving the drying effect of the clothes.

[0014] The clothes treating device comprises an inner drum, which is used for washing clothes. After washing, hot air is introduced into the inner drum to dry the clothes in the inner drum.

[0015] Specifically, the liquid sprayed from the spray hole may flow along the inner drum wall or the outer drum wall to the drainage pipeline of the clothing processing device.

[0016] In a technical solution of the present invention, the heat exchange component includes a first air inlet and a first filter; the first air inlet is arranged on the shell and is connected to the air duct; the first filter is arranged at the first air inlet and is connected to the shell.

[0017] In this technical solution, the heat exchange component also includes a first filter, which is arranged at the first air inlet and is used to filter the gas flowing from the inner drum into the first air inlet. The first air inlet is a connecting port between the inner drum of the clothing processing device and the heat exchange component, that is, the hot and humid air in the inner drum flows into the heat exchange component through the first air inlet. When the inner drum performs other treatments on the clothing, such as washing and drying, the hair, thread and other debris of the clothing will fall off the clothing. By arranging the first filter component at the position of the first air inlet, it is possible to prevent hair, thread and other debris from entering the heat exchange component, thereby avoiding the problem of the heat exchange component being blocked.

[0018] Specifically, the clothing processing device is a drum washing machine. During the process of washing clothes, it is inevitable that debris will remain in the inner drum. Under the action of the fan of the drum washing machine, the lighter debris flows to the first air inlet with the flowing air, and the debris can be blocked outside the heat exchange component by the first filter element, thereby preventing the debris from entering the first cavity and causing blockage of the heat exchange component.

[0019] In a specific embodiment, the first filter element is selected to be a textile with smaller gaps, so that the first filter element can not only prevent debris from entering the heat exchange component, but also adsorb debris with smaller particles, thereby improving the filtering effect on the debris.

[0020] Specifically, cold water can be used as the liquid. After the wet and hot air comes into contact with the water sprayed from the spray hole, it exchanges heat with the sprayed water to cool the wet and hot air. In the process of temperature drop, the water vapor in the wet and hot air condenses into water and drips into the air duct, thereby achieving the effect of cooling the wet and hot air passing through the heat exchange component. Compared with fin-type and sleeve-type heat exchangers, the contact area between the wet and hot air and the liquid is increased, thereby improving the condensation and cooling effect on the air in the inner cylinder.

[0021] It can be understood that the air duct in the heat exchange assembly is connected to the drainage channel of the clothes processing device, so that the water sprayed in the first cavity as liquid and the water condensed from the humid and hot air are discharged from the clothes processing device through the drainage channel of the clothes processing device. The air duct and the drainage channel of the clothes processing device are distributed along the gravity direction, that is, the air duct is higher than the drainage channel, so that the water in the air duct can flow into the drainage channel under the action of gravity.

[0022] The water source connected to the flow channel is a cold water source, so that the temperature of the water in the flow channel is lower than the temperature of the humid hot air, thereby improving the condensation effect of water in the humid hot air.

[0023] In a technical solution of the present invention, a plurality of spray holes are distributed along the flow channel, and at least some of the plurality of spray holes are oriented toward the first filter element.

[0024] In this technical solution, the spray hole is arranged corresponding to the first filter element, and the liquid sprayed from the spray hole can directly act on the first filter element. Under the pressure of the sprayed liquid, debris such as hair scraps and thread ends can fall off the first filter element, playing a role in quickly cleaning the first filter element. By arranging the spray hole on the shell, not only the contact area between the liquid in the shell and the hot and humid air is increased, but also the liquid sprayed from the spray hole can flush the debris on the first filter element, without the need for manual cleaning of the first filter element.

[0025] It can be understood that the first filter element is arranged on the heat exchange component and is located at the first air inlet of the heat exchange component. By cleaning the first filter element by spraying, the subsequent use and maintenance costs of the clothing processing device can be reduced, and the debris on the first filter element can be quickly cleaned without disassembling the clothing processing device.

[0026] Furthermore, since the first filter element is arranged on the heat exchange component and is located at the first air inlet of the heat exchange component, the flow channel is arranged in the air duct, that is, the flow channel is located downwind of the first filter component, and impurities such as hair debris filtered by the first filter component adhere to the upwind side of the first filter component, so the liquid sprayed by the flow channel is sprayed from the downwind side of the first filter component to the upwind side, thereby making it easier to flush impurities such as hair debris filtered by the first filter component away from the first filter component, thereby improving the cleaning effect of the first filter component.

[0027] In a technical solution of the present invention, the heat exchange component further includes a second air inlet, which is arranged on the shell and communicated with the air duct.

[0028] In this technical solution, the second air inlet is connected to the air duct, and the second air inlet connects the air duct with the external air of the heat exchange device, so that the external fresh air outside the heat exchange device can enter the second cavity through the second air inlet, so that the hot and humid air in the clothes can be quickly cooled down during the drying process. After the drying is completed, air is continuously input into the inner drum of the clothes processing device through the second air inlet, so that the air duct system in the entire clothes processing device can be quickly cooled down.

[0029] In a technical solution of the present invention, the shell includes a first shell and a second shell; the first air inlet is arranged on the first shell; the second shell is connected to the first shell, and the second air inlet is arranged on the second shell.

[0030] In this technical solution, the shell of the heat exchange assembly includes a first shell and a second shell, a first cavity is arranged in the first shell, a second cavity is arranged in the second shell, and the first cavity and the second cavity form an air duct. A first air inlet is arranged on the first shell, one end of the first air inlet is connected to the first cavity, and the second end of the first air inlet is connected to the inner drum, so that the hot and humid air in the inner drum of the clothing treatment device can enter the first cavity through the first air inlet, and the hot and humid air entering the first cavity exchanges heat with the heat exchange device. A second air inlet is arranged on the second shell, a first end of the second air inlet is connected to the second cavity, and the other end of the second air inlet is connected to the external air of the clothing treatment device, so that the external air can be input into the second cavity through the second air inlet. The first cavity is connected to the second cavity, and the air after heat exchange with the heat exchange device and the air input from the outside are mixed in the second cavity and then output through the outlet. By mixing the air after heat exchange with the gas input from the outside, the air after heat exchange is cooled, and then the water vapor in the air after heat exchange is condensed, further improving the condensation effect of the water vapor in the air after heat exchange.

[0031] After the clothes are dried, the heating device in the drying channel is turned off so that the heating device no longer heats the air. The fan in the clothes drying device continues to work to drive the hot and humid air in the inner drum to enter the first cavity through the first air inlet for heat exchange. At the same time, the air outside the clothes processing device continues to enter the second cavity through the second air inlet, and the air after heat exchange and the external air are sent into the inner drum of the clothes processing device, so that the inner drum of the clothes processing device is quickly cooled and dried, reducing condensed water in the inner drum.

[0032] It is understandable that the sealing connection between the first shell and the second shell can be specifically welded to each other. It can also be threaded to each other. It can also be flanged to each other, and a sealing gasket is installed between the first shell and the second shell to improve the sealing performance between the first shell and the second shell.

[0033] In a technical solution of the present invention, the first shell is arranged on the top wall of the inner cylinder, and the second shell is arranged on the side wall of the inner cylinder.

[0034] In this technical solution, the top wall of the inner cylinder is the upper position of the circumference of the inner cylinder, and the side wall is the non-circumferential position. The first shell is arranged on the top wall of the inner cylinder, and the second shell is arranged on the side wall of the inner cylinder, so that the installation and fixation of the shell is realized, and the positions of the first shell and the second shell are more reasonable.

[0035] Specifically, the first shell and the second shell may be perpendicular to each other, and the second shell is arranged on the rear side wall of the inner cylinder.

[0036] In a technical solution of the present invention, the heat exchange component further includes a second filter element, which is arranged at the second air inlet and connected to the shell.

[0037] In this technical solution, the heat exchange component further includes a second filter element disposed at the second air inlet. The second air inlet can connect the air duct with the outside of the clothing processing device. The second filter element is disposed on the second air inlet, so that impurities in the external air cannot enter the heat exchange component through the second air inlet, further preventing the ventilation component from being blocked by impurities.

[0038] In one technical solution of the present invention, the second filter element is a sponge.

[0039] In this technical solution, the second filter element is selected as a breathable sponge, which not only allows the external air to freely enter the air duct through the breathable sponge, but also prevents impurities in the external air from entering the air duct.

[0040] It can be understood that the air duct includes a first cavity and a second cavity, the first cavity and the second cavity are interconnected cavities, the air in the first cavity flows out from the inner drum of the clothes processing device, and there is water vapor containing detergent components in the air flowing into the first cavity. In the process of condensing the water vapor, the detergent will form foam inside the heat exchange component. Placing the breathable sponge at the position of the second air inlet can also prevent the foam generated in the second cavity from overflowing from the second air inlet.

[0041] The second filter element is detachably connected to the second air inlet.

[0042] The second filter element is selected as a breathable sponge, and the breathable sponge can be taken out from the second air inlet, which is convenient for daily cleaning and maintenance of the breathable sponge.

[0043] A second aspect of the present invention provides a clothing processing device, comprising a heat exchange component as in any of the above technical solutions, so that the clothing processing device has all the beneficial effects of the heat exchange component in any of the above technical solutions.

[0044] In addition, the clothes processing device in the above technical solution provided by the present invention may also have the following additional technical features:

[0045] In a technical solution of the present invention, the clothes processing device further includes an outer barrel, and the shell is connected to the outer barrel.

[0046] In this technical solution, one end of the shell is provided with a first air inlet which is connected to the outer barrel. The condensed water in the air duct and the sprayed liquid can flow along the outer barrel to the drainage channel of the clothing processing device through the first air inlet. The liquid sprayed on the first filter component can also flow along the outer barrel to the drainage channel of the clothing processing device, thereby avoiding liquid accumulation in the air duct and ensuring smooth drainage of the heat exchange component.

[0047] And because the liquid in the air duct flows along the outer barrel into the drainage channel of the clothing processing device, the liquid flowing along the outer barrel can lower the temperature of the outer barrel, thereby lowering the temperature of the hot air between the outer barrel and the inner barrel, thereby liquefying the water vapor in the hot air between the outer barrel and the inner barrel, further reducing the humidity of the hot air and improving the drying effect of the hot air.

[0048] In one technical solution of the present invention, an air outlet is provided on the shell, and the air outlet is connected to the air duct. The clothing processing device also includes an inner drum, a fan, a drying channel and a heating component; the inner drum is embedded in the outer barrel; the air inlet end of the fan is connected to one end of the shell where the air outlet is provided; one end of the drying channel is connected to the air outlet end of the fan, and the other end of the drying channel is connected to the inner drum; the heating component is arranged in the drying channel.

[0049] In this technical solution, the clothes processing device also includes a fan, which can drive air flow, so that the hot and humid air in the inner drum of the clothes processing device flows through the second air inlet through the heat exchange component and then flows back to the inner drum. In addition, the fan can make the fresh air outside flow through the first air inlet through the heat exchange component and then enter the inner drum. The specific selection and setting position of the fan can be reasonably configured according to different clothes processing devices, and no further details will be given here.

[0050] Specifically, when drying clothes, the air is heated by the heating component in the drying tunnel and enters the inner drum under the action of the fan. The hot air evaporates the moisture of the clothes in the inner drum, enters the outer drum, and then enters the heat exchange component through the first air inlet. In the air duct of the heat exchange component, the hot air exchanges heat with the liquid in the flow channel and the liquid sprayed from the spray hole, the hot air is cooled, the water vapor condenses, and the humidity in the hot air is reduced. The dehumidified hot air then enters the drying tunnel under the action of the fan, thus forming a cycle.

[0051] The heat exchange component also includes a first sealing member, which is arranged on the first air inlet.

[0052] The heat exchange component also includes a first seal arranged at the first air inlet position. By arranging the first seal at the first air inlet position, it is possible to prevent gas and liquid from flowing out at the first air inlet position, thereby improving the sealing performance of the heat exchange component.

[0053] The heat exchange component also includes a second sealing member disposed on the air outlet.

[0054] In this design, the heat exchange component also includes a second seal arranged at the air outlet position, which can prevent liquid and gas inside the heat exchange component from flowing out of the heat exchange component through the air outlet, thereby improving the overall sealing performance of the heat exchange component.

[0055] The heating assembly includes an electric heating pipe and a protective cover. The protective cover is made of a material with good thermal conductivity. The protective cover can prevent the electric heating pipe from directly contacting the gas. In the event that the filter device in the heat exchange assembly fails, the protective cover can prevent the electric heating pipe from contacting with impurities, resulting in damage to the clothing treatment device.

[0056] In one technical solution of the present invention, the clothing processing device is a washing machine, a dryer or an all-in-one washing and drying machine.

[0057] In this technical solution, the clothes processing device includes a washing machine, a clothes dryer, and a washing and drying machine. Of course, it can also be other devices with a clothes drying function, not limited to the above three types.

[0058] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0073] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0074] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0075] Refer to the following Figures 1 to 11 A heat exchanging assembly 100 and a laundry treating apparatus according to some embodiments of the present invention are described.

[0076] Embodiment 1:

[0077] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a heat exchange component 100, including a shell 110, an air duct 116, a flow channel 128 and a plurality of spray holes 124; the air duct 116 is arranged in the shell 110; the flow channel 128 is arranged on the shell 110; the plurality of spray holes 124 are arranged on the shell 110, connected with the flow channel 128, and arranged toward the air duct 116.

[0078] The heat exchange component 100 provided by the present invention is provided with a flow channel 128 and a spray hole 124 on the shell 110. The flow channel 128 is connected with the spray hole 124. After the liquid enters the flow channel 128, it can be sprayed out from the spray hole 124 and sprayed into the air duct 116 or on the filter element, thereby flushing the hair debris in the air duct 116 or on the filter element, avoiding the accumulation of hair debris in the air duct 116 or on the filter element, and ensuring that the hair debris in the air duct 116 or on the filter element will not circulate into the inner drum of the clothing processing device with the hot air.

[0079] In addition, the flow channel 128 and the spray hole 124 are provided on the housing 110, and no additional spray pipe is required in the air duct 116, thereby simplifying the structure and production process of the heat exchange assembly 100. The spray hole 124 is provided on the housing 110, so that the liquid sprayed from the spray hole 124 is more uniform, thereby improving the flushing effect on the air duct 116 and the filter element.

[0080] When the heat exchange assembly 100 dries clothes, the hot air flowing out of the clothes processing device enters the air duct 116 and exchanges heat with the liquid sprayed out of the spray hole in the air duct 116. After the heat exchange, the temperature of the hot air flowing out of the clothes processing device is reduced, so that the high-temperature water vapor contained in the hot air is condensed into liquid water, thereby reducing the moisture content in the hot air, making the hot air flowing back into the clothes processing device drier, thereby improving the drying effect of the clothes.

[0081] Since the drying effect of clothes is improved, clothes can be dried faster, thereby improving the drying efficiency of the clothes processing device and shortening the time required for clothes drying. In addition, the energy loss in the process of drying clothes can be reduced, thereby reducing the cost required for clothes drying by the clothes processing device and improving the quality of the clothes processing device.

[0082] The housing 110 is provided with a liquid inlet 126 , which is communicated with the flow channel 128 , so that the main liquid inlet pipe of the clothing processing device can transport liquid into the flow channel 128 through the liquid inlet 126 .

[0083] like Figure 3 As shown, the direction indicated by the arrow in the figure is the flow direction of the hot air.

[0084] Embodiment 2:

[0085] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0086] The heat exchange assembly 100 is used in a clothes processing device, which includes an inner drum, and a through hole is arranged on the inner drum; the positions of the plurality of spray holes 124 are staggered with the positions of the through holes.

[0087] In this technical solution, the positions of the plurality of spray holes 124 are staggered from the positions of the through holes, so as to prevent the liquid sprayed from the spray holes 124 from entering the inner drum through the through holes and wetting the clothes in the inner drum, thereby improving the drying effect of the clothes.

[0088] The clothes treating device comprises an inner drum, which is used for washing clothes. After washing, hot air is introduced into the inner drum to dry the clothes in the inner drum.

[0089] Specifically, the liquid sprayed from the spray hole 124 may flow along the inner drum wall or the outer drum wall to the drainage pipeline of the clothing processing device.

[0090] Embodiment three:

[0091] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0092] like Figure 1 and Figure 3 As shown, the heat exchange assembly 100 includes a first air inlet 130 and a first filter element 160 ; the first air inlet 130 is disposed on the shell 110 and communicated with the air duct 116 ; the first filter element 160 is disposed at the first air inlet 130 and connected to the shell 110 .

[0093] In this embodiment, the heat exchange assembly 100 further includes a first filter 160, which is disposed at the first air inlet 130 and is used to filter the gas flowing from the inner drum into the first air inlet 130. The first air inlet 130 is a connecting port between the inner drum of the clothing treatment device and the heat exchange assembly 100, that is, the hot and humid air in the inner drum flows into the heat exchange assembly 100 through the first air inlet 130. When the inner drum performs other treatments on the clothing, such as washing and bleaching, the hair scraps, thread ends and other debris on the clothing will fall off the clothing. By arranging the first filter assembly at the position of the first air inlet 130, the hair scraps, thread ends and other debris can be prevented from entering the heat exchange assembly 100, thereby avoiding the problem of the heat exchange assembly 100 being blocked.

[0094] Specifically, the clothing processing device is a drum washing machine. During the process of washing clothes, it is inevitable that debris will remain in the inner drum. Under the action of the fan 300 of the drum washing machine, the lighter debris flows with the flowing air to the first air inlet 130, and the debris can be blocked outside the heat exchange component 100 by the first filter element 160, thereby preventing the debris from entering the first cavity and causing blockage of the heat exchange component 100.

[0095] like Figure 1As shown, in a specific embodiment, the first filter element 160 is selected to be a textile with smaller gaps, so that the first filter element 160 can not only prevent debris from entering the heat exchange component 100, but also adsorb debris with smaller particles, thereby improving the filtering effect on debris.

[0096] Specifically, Figure 6 As shown, cold water can be used as the liquid. After the moist hot air contacts the water sprayed from the spray hole 124, it exchanges heat with the sprayed water to cool the moist hot air. In the process of temperature drop, the water vapor in the moist hot air condenses into water and drips into the air duct 116, thereby achieving the effect of cooling the moist hot air passing through the heat exchange component 100. Compared with fin-type and sleeve-type heat exchangers, the contact area between the moist hot air and the liquid is increased, thereby improving the condensation and cooling effect on the air in the inner cylinder.

[0097] It can be understood that the air duct 116 in the heat exchange assembly 100 is connected to the drainage channel of the clothes processing device, so that the water sprayed in the first cavity as liquid and the water condensed from the humid and hot air are discharged from the clothing processing device through the drainage channel of the clothing processing device. The air duct 116 and the drainage channel of the clothing processing device are distributed along the gravity direction, that is, the air duct 116 is arranged higher than the drainage channel, so that the water in the air duct 116 can flow into the drainage channel under the action of gravity.

[0098] The water source connected to the flow channel 128 is a cold water source, so that the temperature of the water in the flow channel 128 is lower than the temperature of the humid hot air, thereby improving the condensation effect of the water in the humid hot air.

[0099] Embodiment 4:

[0100] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0101] like Figure 3 As shown, the plurality of spray holes 124 are distributed along the flow channel 128 , and at least some of the plurality of spray holes 124 are directed toward the first filter element 160 .

[0102] In this embodiment, the spray hole 124 is arranged corresponding to the first filter element 160, and the liquid sprayed from the spray hole 124 can directly act on the first filter element 160. Under the pressure of the sprayed liquid, debris such as hair scraps and thread ends can fall off the first filter element 160, which plays a role in quickly cleaning the first filter element 160. By arranging the spray hole 124 on the housing 110, not only the contact area between the liquid in the housing 110 and the wet and hot air distribution is increased, but also the debris on the first filter element 160 can be flushed by the liquid sprayed from the spray hole, and the first filter element 160 does not need to be cleaned manually.

[0103] It can be understood that the first filter element 160 is arranged on the heat exchange component 100, located at the first air inlet of the heat exchange component 100. By cleaning the first filter element 160 by spraying, the subsequent use and maintenance costs of the clothing processing device can be reduced, and the debris on the first filter element 160 can be quickly cleaned without disassembling the clothing processing device.

[0104] Furthermore, since the first filter element 160 is disposed on the heat exchange component 100 and is located at the first air inlet of the heat exchange component 100, the flow channel is disposed in the air duct 116, that is, the flow channel is located downwind of the first filter component, and impurities such as hair debris filtered by the first filter component adhere to the upwind side of the first filter component, so the liquid sprayed by the flow channel is sprayed from the downwind side of the first filter component to the upwind side, thereby making it easier to flush impurities such as hair debris filtered by the first filter component away from the first filter component, thereby improving the cleaning effect of the first filter component.

[0105] Embodiment five:

[0106] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0107] like Figure 1 and Fig. 9 As shown, the heat exchange assembly 100 further includes a second air inlet 140 , which is disposed on the housing 110 and communicated with the air duct 116 .

[0108] In this embodiment, if Figure 8 , Fig. 9 and Fig.10 As shown, the second air inlet 140 is connected to the air duct 116, and the second air inlet 140 connects the air duct 116 with the external air of the heat exchange device, so that the external air outside the heat exchange device can enter the second cavity through the second air inlet 140, so that the hot and humid air in the clothes can be quickly cooled down during the drying process. After the drying is completed, air is continuously input into the inner drum of the clothes processing device through the second air inlet 140, so that the air duct 116 system in the entire clothes processing device can be quickly cooled down.

[0109] Embodiment six:

[0110] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0111] like Figure 4 , Figure 5 and Figure 7As shown, the housing 110 includes a first housing 112 and a second housing 114 ; the first air inlet 130 is disposed on the first housing 112 ; the second housing 114 is connected to the first housing 112 , and the second air inlet 140 is disposed on the second housing 114 .

[0112] In this embodiment, the housing 110 of the heat exchange assembly 100 includes a first housing 112 and a second housing 114. A first cavity is provided in the first housing 112, and a second cavity is provided in the second housing 114. The first cavity and the second cavity form an air duct 116. A first air inlet 130 is provided on the first housing 112, one end of the first air inlet 130 is connected to the first cavity, and the second end of the first air inlet 130 is connected to the inner drum, so that the hot and humid air in the inner drum of the clothing treatment device can enter the first cavity through the first air inlet 130, and the hot and humid air entering the first cavity exchanges heat with the heat exchange device. A second air inlet 140 is provided on the second housing 114, a first end of the second air inlet 140 is connected to the second cavity, and the other end of the second air inlet 140 is connected to the external air of the clothing treatment device, so that the external air can be input into the second cavity through the second air inlet 140. The first cavity is connected to the second cavity, and the air after heat exchange with the heat exchange device and the air input from the outside are mixed in the second cavity and then output through the air outlet 150. By mixing the air after heat exchange with the gas input from the outside, the air after heat exchange is cooled, and then the water vapor in the air after heat exchange is condensed, further improving the condensation effect of the water vapor in the air after heat exchange.

[0113] After the clothes are dried, the heating device in the drying channel is turned off so that the heating device no longer heats the air. The fan 300 in the clothes drying device continues to work to drive the hot and humid air in the inner drum to enter the first cavity through the first air inlet 130 for heat exchange. At the same time, the air outside the clothes processing device continues to enter the second cavity through the second air inlet 140, and the air after heat exchange and the external air are sent into the inner drum of the clothes processing device, so that the inner drum of the clothes processing device is quickly cooled and dried, reducing the condensed water in the inner drum.

[0114] It is understandable that the first shell 112 and the second shell 114 are sealed and connected, and specifically, the first shell 112 and the second shell 114 can be welded. Alternatively, the first shell 112 and the second shell 114 can be connected by threads. Alternatively, the first shell 112 and the second shell 114 can be flange-connected, and a sealing gasket is installed between the first shell 112 and the second shell 114 to improve the sealing performance between the first shell 112 and the second shell 114.

[0115] Embodiment seven:

[0116] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0117] The first shell 112 is disposed on the top wall of the inner tube, and the second shell 114 is disposed on the side wall of the inner tube.

[0118] In this technical solution, the first shell 112 is arranged on the top wall of the inner tube, and the second shell 114 is arranged on the side wall of the inner tube, so that the installation and fixation of the shell 110 is realized and the positions of the first shell 112 and the second shell 114 are more reasonable.

[0119] Specifically, the first shell 112 and the second shell 114 are perpendicular to each other, and the second shell 114 is disposed on the rear side wall of the inner cylinder.

[0120] Embodiment eight:

[0121] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0122] like Fig. 9 As shown, the heat exchange assembly 100 further includes a second filter element 180 , which is disposed at the second air inlet and connected to the housing 110 .

[0123] In this embodiment, the heat exchange assembly 100 further includes a second filter 180 disposed at the second air inlet 140. The second air inlet 140 can connect the air duct 116 with the outside of the clothing processing device. The second filter 180 is disposed on the second air inlet 140, so that impurities in the external air cannot enter the heat exchange assembly 100 through the second air inlet 140, further preventing the ventilation assembly from being blocked by impurities.

[0124] Embodiment nine:

[0125] This embodiment provides a heat exchange assembly 100. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0126] The second filter element 180 is a sponge.

[0127] In this embodiment, the second filter element 180 is selected as a breathable sponge, which not only allows external air to freely enter the air duct 116 through the breathable sponge, but also prevents impurities in the external air from entering the air duct 116.

[0128] It can be understood that the air duct 116 includes a first cavity and a second cavity, the first cavity and the second cavity are interconnected cavities, the air in the first cavity flows out from the inner drum of the clothes processing device, and the air flowing into the first cavity also contains water vapor containing detergent components, and in the process of condensing the water vapor, the detergent will form foam inside the heat exchange component 100. Placing the breathable sponge at the position of the second air inlet 140 can also prevent the foam generated in the second cavity from overflowing from the second air inlet 140.

[0129] The second filter element 180 is detachably connected to the second air inlet 140 .

[0130] The second filter element 180 is selected as a breathable sponge, and the breathable sponge can be taken out from the second air inlet 140, which is convenient for daily cleaning and maintenance of the breathable sponge.

[0131] Embodiment ten:

[0132] The present invention provides a clothes processing device, comprising a heat exchange assembly 100 as in any of the above embodiments, so the clothes processing device has all the beneficial effects of the heat exchange assembly 100 in any of the above embodiments.

[0133] Embodiment eleven:

[0134] This embodiment provides a clothing processing device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0135] like Fig.11 As shown, the laundry treating apparatus further includes an outer tub 200 , and the housing 110 is connected to the outer tub 200 .

[0136] In this embodiment, the shell 110 is provided with a first air inlet 130 at one end which is connected to the outer barrel 200. The condensed water and the sprayed liquid in the air duct 116 can flow along the outer barrel 200 to the drainage channel of the clothing processing device through the first air inlet 130. The liquid sprayed on the first filter component can also flow along the outer barrel 200 to the drainage channel of the clothing processing device, thereby avoiding the accumulation of liquid in the air duct 116 and ensuring the smoothness of the drainage of the heat exchange component 100.

[0137] And because the liquid in the wind-proof drum flows along the outer drum 200 to the drainage channel of the clothing processing device, the liquid flowing along the outer drum 200 can lower the temperature of the outer drum 200, so as to lower the temperature of the hot air between the outer drum 200 and the inner drum, thereby liquefying the water vapor in the hot air between the outer drum 200 and the inner drum, further reducing the humidity of the hot air and improving the drying effect of the hot air.

[0138] Embodiment 12:

[0139] This embodiment provides a clothing processing device. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

The clothing processing device also includes an inner drum, a fan 300, a drying channel 400 and a heating component; the inner drum is embedded in the outer barrel 200; the air inlet end of the fan 300 is connected to one end of the shell 110 where the air outlet 150 is provided; one end of the drying channel 400 is connected to the air outlet end of the fan 300, and the other end of the drying channel 400 is connected to the inner drum; the heating component is arranged in the drying channel 400.

[0141] In this embodiment, the clothes processing device further includes a fan 300, which can drive air flow, so that the hot and humid air in the inner drum of the clothes processing device flows through the heat exchange component 100 through the second air inlet 140 and then flows back to the inner drum, and the fresh air outside flows through the heat exchange component 100 through the first air inlet 130 and then enters the inner drum. The specific selection and setting position of the fan 300 can be reasonably configured according to different clothes processing devices, and no further details are given here.

[0142] Specifically, when drying clothes, the air is heated by the heating component in the drying tunnel 400 and enters the inner drum under the action of the fan 300. The hot air evaporates the moisture of the clothes in the inner drum, enters the outer barrel 200, and then enters the heat exchange component 100 through the first air inlet 130. In the air duct 116 of the heat exchange component 100, the hot air exchanges heat with the liquid in the flow channel and the liquid sprayed from the spray hole, the hot air is cooled, the water vapor condenses, and the humidity in the hot air is reduced. The dehumidified hot air then enters the drying tunnel 400 under the action of the fan 300, thereby forming a cycle.
