[0029] The heat pump system 3 is also equipped with a second control valve 200 that provides fresh air to the washing drum 2. A fresh air duct 30 is connected to the air inlet of the fan 31. The second control valve 200 is located at the end of the fresh air duct 30 and is used to control the opening and closing of the fresh air duct 30. For the washing drum 2, since there is a lot of water vapor and high humidity inside the drum after washing, the above-mentioned fresh air duct 30 is set up to prevent the water vapor inside the drum from becoming moldy and smelly. Furthermore, the fresh air input process can be realized by the fan 31 of the heat pump system 3. The fresh air system and the return air system share the same air duct. The fan 31 has a strong load capacity, so there is no need to set up an additional fan 31, resulting in low production and operating costs.

[0030] An air inlet is provided at the top edge of the front end of the washing drum 2, and the front end of the second air supply duct 20 is bent downward and connected to the air inlet. This structure is adopted to shorten the air supply stroke and reduce wind resistance.

[0031] The first air supply duct 10 extends vertically from bottom to top to form a teardrop-shaped air outlet channel 10a with its tip pointing downwards. The rear end face of the drying cylinder 1 is the air inlet face, and the upper circular portion of the teardrop-shaped air outlet channel 10a covers the rear side of the air inlet face of the drying cylinder 1. A transition cavity 11 is provided at the front end of the drying cylinder 1, located below the drying cylinder 1 and before the heat pump system 3. A filter assembly 5 is installed in this transition cavity 11. The inner bottom wall of the drying cylinder 1 is vertically connected to the transition cavity 11 near the front end. The first return air duct 01 is located at the top of the heat pump system 3 and extends front to back. The rear part of the transition cavity 11 is connected to the front end of the first return air duct 01. Using this structure, air is supplied to the drying cylinder 1 from a larger blowing surface, improving the drying quality.

[0032] The washing drum 2 has an air outlet located near the rear end at the top. The second return air duct 02 is vertically connected to the heat pump system 3 and its lower end is connected to the air outlet. A third control valve 300 is installed in the second return air duct 02 to control its on / off state. This structure facilitates the control of whether the washing drum 2 emits air.

[0033] In this embodiment, the drying drum 1 and the washing drum 2 are arranged vertically, and a heat pump system 3 that can provide hot air for drying to both drums is set between them. The drying drum 1 is dedicated to drying and can meet the user's high-quality drying needs. The washing drum 2 can realize the washing and drying functions in one, which can meet the user's quick and convenient washing and drying needs. This embodiment can meet the different needs of users, and the upper and lower drums share a set of heat pump system 3, without the need to add more accessories. This not only reduces the cost of use, but also helps to improve space utilization and facilitates installation and assembly.

[0034] The operation process of this embodiment is as follows:

[0035] (1) Drying of the upper cylinder (drying cylinder 1): When drying cylinder 1 is dried independently, the upper and lower cylinder air duct switching valves are switched to the upward blowing state, that is, the first control valve 100 opens the first air supply duct 10; the lower cylinder return air valve is closed and the fresh air valve is closed, that is, the third control valve 300 isolates the second return air duct 02 and the second control valve 200 isolates the fresh air duct 30; the heat pump system 3 is running;

[0036] (2) Drying the lower drum (washing drum 2): When the washer-dryer is drying, the upper and lower drum air duct switching valves are switched to the downward blowing state, that is, the first control valve 100 opens the second air supply pipe 20; the lower drum return air valve is opened and the fresh air valve is closed, that is, the third control valve 300 connects the second return air pipe 02 and the second control valve 200 isolates the fresh air pipe 30; the heat pump system 3 is running; at this time, due to the control of the upper and lower drum air duct switching valves, the air blows to the lower drum and no air enters the upper drum, so the air circulation cannot be formed. Due to the air pressure limitation, the fan 31 cannot draw air from the upper drum, thus ensuring the air circulation of the lower drum. The air does not run from the first air supply pipe 10.

[0037] (3) Fresh air mode: The washer-dryer uses fresh air mode to prevent water vapor from causing mold and odor. At this time, the upper and lower drum air duct switching valves are switched to the downward blowing state, that is, the first control valve 100 opens the second air supply duct 20, the lower drum return air valve is closed and the fresh air valve is opened, that is, the third control valve 300 connects the second return air duct 02 and the second control valve 200 connects the fresh air duct 30; the heat pump system 3 is running.
