Exemplarily, the sliding groove 312 may be provided on the first housing 31, and the sliding groove 312 may also be provided on the second housing 32, or both the first housing 31 and the second housing 32 are provided with sliding grooves. 312. This embodiment is not limited here, and only needs to satisfy the guiding function of the filter 70.

In this embodiment, in an achievable manner in which the slide groove 312 is located in the first housing 31, the slide groove 312 is provided on the bottom wall of the first housing 31, and the slide groove 312 is located between the air inlet 313 and the water groove 315. And is connected to the first installation port 319; the second housing 32 is provided with a limit plate 325, and the limit plate 325 is arranged opposite to the sliding groove 312. When the filter 70 slides into the heat exchange channel along the sliding groove 312, the limit The plate 325 limits the position of the filter screen 70 to prevent the filter screen 70 from shaking in the second housing 32.

Continuing to refer to Figure 2, the washing machine 1 provided in this embodiment works during the drying process: the cold air in the inner tub 100 flows into the air inlet duct 90 through the first hole 101 through the dust removal net 102, and passes through the air inlet 313 The filter screen 70 flows into the evaporator 50. The evaporator 50 condenses the moisture in the cold air into condensed water to form dry air. The condensed water enters the drain pipe 110 through the drain hole 3153 and is discharged out of the washing machine 1, and the dry air flows into the compressor 20. The compressor 20 converts the dry air into high-pressure dry air. The high-pressure dry air enters the condenser 40. The condenser 40 heats the high-pressure dry air to form hot air. The fan 60 draws the hot air into the fan 60 through the air outlet 314. In the air inlet 61, hot air flows into the air outlet duct 80 through the air outlet 62 of the fan 60, and flows into the inner tube 100 through the second hole 1031 of the ring gasket 103, and then the clothes in the inner tube 100 are dried.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the application, not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present application. Scope.
