According to the heat exchange assembly provided by the invention, the flow channel and the spraying hole are formed in the shell, the flow channel is communicated with the spraying hole, liquid can be sprayed out from the spraying hole after entering the flow channel and is sprayed into the air channel or the filtering piece, and then the flock in the air channel or on the filtering piece is washed, so that the flock is prevented from being accumulated on the air channel or the filtering piece, and the flock in the air channel or on the filtering piece is ensured not to circulate to the inner cylinder of the clothes treatment device along with hot air.
And the shell is provided with the flow channel and the spraying hole, so that an additional spraying pipe is not required to be arranged in the air channel, and the structure and the production process of the heat exchange assembly are simplified. Set up on the casing and spray the hole for spray hole spun liquid more even, promote the washing effect to wind channel and filtration piece.
When clothes are dried, hot air flowing out of the clothes treatment device enters the air channel and exchanges heat with liquid sprayed out of the spraying holes in the air channel. After heat exchange, the temperature of hot air flowing out of the clothes treatment device is reduced, so that high-temperature water vapor contained in the hot air is condensed into liquid water, the moisture content in the hot air is reduced, the hot air flowing back into the clothes treatment device is drier, and the drying effect on clothes is improved.
Due to the fact that the drying effect on the clothes is improved, the clothes can be dried more quickly, the drying efficiency of the clothes treatment device is improved, and the time required by drying the clothes is shortened. And the energy loss in the clothes drying process can be reduced, so that the cost for drying the clothes by the clothes treatment device is reduced, and the quality of the clothes treatment device is improved. In addition, the heat exchange assembly in the technical scheme provided by the invention can also have the following additional technical characteristics:

The heat exchange assembly 100 and the laundry treating apparatus according to some embodiments of the present invention will be described with reference to fig. 1 to 11.
The first embodiment is as follows:
as shown in fig. 1, 2 and 3, the present invention provides a heat exchange assembly 100, which includes a housing 110, an air duct 116, a flow passage 128 and a plurality of spray holes 124; the air duct 116 is disposed in the housing 110; the flow passage 128 is disposed on the housing 110; a plurality of spray holes 124 are disposed on the housing 110, communicate with the flow passage 128, and are disposed toward the air duct 116.

And the flow channel 128 and the spray holes 124 are arranged on the shell 110, so that an additional spray pipe does not need to be arranged in the air duct 116, and the structure and the production process of the heat exchange assembly 100 are simplified. The spraying holes 124 are formed in the shell 110, so that liquid sprayed out of the spraying holes 124 is more uniform, and the washing effect on the air duct 116 and the filter pieces is improved.
When the heat exchange assembly 100 dries the clothes, the hot air flowing out of the clothes treatment device enters the air duct 116, and exchanges heat with the liquid sprayed out of the spraying holes in the air duct 116. After heat exchange, the temperature of hot air flowing out of the clothes treatment device is reduced, so that high-temperature water vapor contained in the hot air is condensed into liquid water, the moisture content in the hot air is reduced, the hot air flowing back into the clothes treatment device is drier, and the drying effect on clothes is improved.
Due to the fact that the drying effect on the clothes is improved, the clothes can be dried more quickly, the drying efficiency of the clothes treatment device is improved, and the time required by drying the clothes is shortened. And the energy loss in the clothes drying process can be reduced, so that the cost required by the clothes drying device for drying the clothes is reduced, and the quality of the clothes treating device is improved.

Example two:
the present embodiment provides a heat exchange assembly 100, and in addition to the technical features of the above embodiments, the present embodiment further includes the following technical features.
The heat exchange assembly 100 is used for a clothes treatment device, and the clothes treatment device comprises an inner barrel, wherein a through hole is formed in the inner barrel; the positions of the plurality of spray holes 124 are staggered with the positions of the through holes.
In the technical scheme, the positions of the spraying holes 124 are staggered with the positions of the through holes, so that the phenomenon that the clothes in the inner barrel are wetted by the liquid sprayed out of the spraying holes 124 after entering the inner barrel through the through holes is avoided, and the drying effect on the clothes is further improved.
The clothes treatment device comprises an inner drum, wherein the inner drum is used for washing clothes, and hot air is introduced into the inner drum after the clothes are washed so as to dry the clothes in the inner drum.
Specifically, the liquid sprayed from the spray holes 124 may flow along the inner or outer tub wall into a drain line of the laundry treating apparatus.

As shown in fig. 1 and 3, the heat exchange assembly 100 includes a first inlet 130 and a first filter element 160; the first air inlet 130 is disposed on the housing 110 and communicated with the air duct 116; the first filter 160 is disposed at the first air inlet 130 and connected to the housing 110.
In this embodiment, the heat exchange assembly 100 further comprises a first filter element 160 disposed at the first gas inlet 130 for filtering the gas flowing from the inner tube into the first gas inlet 130. The first air inlet 130 is a communication port between an inner drum of the laundry processing apparatus and the heat exchange assembly 100, that is, hot and humid air in the inner drum flows into the heat exchange assembly 100 through the first air inlet 130, and in the process of performing other processing on the laundry, for example, washing, bleaching, etc., the inner drum can cause sundries such as lint and thread of the laundry to fall off from the laundry, and the first filtering assembly is disposed at the position of the first air inlet 130, so that the sundries such as the lint and the thread can be prevented from entering the heat exchange assembly 100, and the problem that the heat exchange assembly 100 is blocked is avoided.
Specifically, the laundry processing apparatus is a drum washing machine, during the process of washing the laundry in the inner drum, the impurities are inevitably left in the inner drum, and under the action of the blower 300 of the drum washing machine, the impurities with light mass flow to the first air inlet 130 along with the flowing air, and the impurities can be blocked outside the heat exchange assembly 100 by the first filtering member 160, so as to avoid the problem of blocking the heat exchange assembly 100 due to the impurities entering the first cavity.

It can be understood that the air duct 116 of the heat exchange assembly 100 is communicated with the water drainage channel of the clothes treatment device, so that both the water sprayed in the first cavity as liquid and the water condensed from the hot and humid air are discharged out of the clothes treatment device through the water drainage channel of the clothes treatment device. The air duct 116 and the drainage channel of the clothes treatment device are distributed along the gravity direction, that is, the air duct 116 is arranged higher than the drainage channel, so that water in the air duct 116 can flow into the drainage channel under the action of gravity.
The water source connected to the flow passage 128 is a cold water source, so that the temperature of water in the flow passage 128 is lower than that of the hot and humid air, and the condensation effect of water in the hot and humid air is improved.
Example four:
