the cleaning evaporator 101 is disposed in the refrigerating compartment 201. Because the food materials such as fruit vegetables are generally deposited to walk-in 201, walk-in 201 generally has great humidity, when needs self-cleaning, at first through the water level sensor detection water tank 108 of water tank whether satisfy the requirement (the too low washing water volume that probably exists of water level is not enough, wash unclean problem), if satisfy the water level requirement, control valve 111 opens, carries out the washing flow, waits to wash the aluminium foil heater at regional top after the completion and opens the stoving, degerming anion device puts into operation simultaneously.

If the water level in the water tank 108 is insufficient, a water replenishing process is executed, specifically, humidity is detected through a humidity sensor, if the relative humidity is larger than 50%, the switching valve 106 is switched to the second state, the cleaning evaporator 101 is put into operation, the cleaning evaporator 101 enables air passing through the cleaning evaporator to be cooled and condensed, and then frost is formed, when the low-temperature continuous operation of the cleaning evaporator is detected for a certain time, electric heating is started to defrost, the fan is reversely rotated, hot air is blown to the cleaning evaporator 101, the frost is melted, the frost water falls into the water receiving tray 109, and the frost water in the water receiving tray 109 enters the water tank 108 through a pipeline to be accumulated. During defrosting, the switching valve 106 is switched to the first state, and the cleaning evaporator 101 stops operating.

If the relative humidity in the refrigerating chamber 201 is detected to be low when the cleaning evaporator 101 works, a refrigerating door (a fan) or a refrigerating drawer is automatically opened and pushed out, and the humidity of the outside high-humidity air is used as supplement, so that the cleaning evaporator 101 works normally. If the environmental conditions are too dry at this time, and water cannot be produced, words such as 'dry, please place water cup' and the like are directly displayed on the display of the refrigerator to remind the user to place a water source in the refrigerating chamber 201. When the water volume in the water tank 108 meets the minimum water level line, the cleaning evaporator 101 can stop frosting, otherwise, the circulating water making supplement is continuously carried out.

Through the drawer after automatic cleaning, can let blood water, water stain etc. that remain before washed away by clean, give the better experience of user. Of course, the user is required to remove the ingredients of the instant freezer drawer 202 prior to cleaning. Or a camera is added, and when the situation that the instant freezing drawer 202 is empty for a period of time is monitored, the automatic cleaning function is automatically started. The automatic cleaning function can also be used for cleaning for multiple times in a segmented mode, such as 3 times of periodic cleaning in one night.
