The drying component 3 is also provided with a control valve 31 for switching the air supply path between the first air duct 301 and the second air duct 302; the gas collecting chamber 21 is also connected to the downpipe 4 under the water tank 1 through the second air duct 20. A one-way valve 200 is provided in the second air duct 20, which only allows gas to be transported to the downpipe 4 and prevents the gas in the downpipe 4 from flowing into the gas collecting chamber 21.

[0027] The processing method of frozen vegetables in the present embodiment is:

[0028] Place frozen vegetables on door 2;

[0029] The drying component 3 is operated, and the control valve 31 switches the air supply path to the second air duct 302. The drying component 3 delivers the heated air into the air collecting cavity 21 through the first air guide pipe 10. A warming area for heating food is formed on the upper surface of the door body 2. Frozen food placed in the warming area is heated and thawed.

[0030] The hot air circulates in the air collecting chamber 21 and is sent into the sewer pipe 4 through the second air guide pipe 20 to perform heating and sterilization treatment in the sewer pipe 4 .

[0031] After the washing machine finishes washing the dishes in the washing chamber, the drying component 3 is operated, and the control valve 31 switches the air supply path to the first air duct 301. The drying component 3 delivers the heated air to the water tank through the first air duct 301 and the air inlet 120 on the side wall of the water tank 1, and the dried hot and humid gas is discharged through the exhaust port on the side wall of the water tank 1.

[0032] In this embodiment, the water tank 1 includes a first water tank 11 and a second water tank 12 arranged adjacent to each other. The first water tank 11 defines a washing chamber of the washing machine. A drain surface 22 is formed on the door body 2 to timely guide the accumulated water in the warm vegetable area into the second water tank 12. During the thawing process of frozen vegetables, the frozen vegetables produce condensed water because their surface temperature is lower than the room temperature. As the thawing process proceeds, the condensed water and the water stains overflowing from the frozen vegetables are guided into the second water tank 12 by the drain surface 22 to reduce the accumulated water in the warm vegetable area. With the above structure, the accumulated water generated during the thawing process is promptly drained into the second water tank, which not only avoids the overflow of the accumulated water on the door body of the washing machine, but also avoids the heat energy wasted by the heating source for heating the accumulated water, which is conducive to improving the thawing efficiency of frozen vegetables.

[0033] The upper surface of the door body 2 is formed with an inclined surface which gradually slopes downward from the edge away from the second water tank 12 toward the second water tank 12, and the inclined surface constitutes a drain surface 22, and the warm food area is formed on the drain surface 22. With the above structure, it is convenient to guide the accumulated water on the door body 2 into the second water tank 12 in time. Based on this, the door body 2 also has an independent drain function. For example, the cleaned fruits and vegetables or tableware can be placed on the drain surface to achieve the draining effect.

[0034] The inclined surface is also provided with a plurality of ribs 221 extending along the inclined direction thereof, and the ribs 221 form a limiting structure that can stably place the frozen vegetables and a diversion structure that can guide the accumulated water to the second water tank 12. The provision of the ribs, on the one hand, increases the friction force to prevent the items on the door body from sliding down due to the inclined surface, and on the other hand, plays a diversion effect to improve the efficiency of draining the accumulated water.

[0035] The cleaning machine of this embodiment further includes a switch assembly 5 for controlling the opening and closing of the door body 2 and whether the cleaning machine is running or not, and the switch assembly 5 is arranged at the rear edge of the second water tank 12.
