Air cooled refrigerator defrosting and humidifying device and control method thereof

Abstract

The invention discloses an air cooled refrigerator defrosting and humidifying device and a control method thereof, and relates to the technical field of refrigerators. The air cooled refrigerator defrosting and humidifying device comprises a refrigerator body, a refrigerating chamber, a freezing chamber, a refrigerating system, an air circulating system and a defrosting and humidifying system; therefrigerating system comprises a compressor, an evaporator, a capillary tube, a filter and a condenser; the compressor is mounted inside a compressor chamber below the refrigerating chamber; and theevaporator is communicated with the compressor, and is mounted inside an evaporator chamber on the rear side of the refrigerating chamber. The air cooled refrigerator defrosting and humidifying deviceprovided by the invention uses the principle that when solid frost on the evaporator is changed to be in a liquid state, heat is absorbed and the temperature is not changed; when defrosting is performed, the main control panel of the refrigerator controls a refrigerating blower to blow moist air produced by defrosting into the refrigerating chamber for moistening; by using a forced convection method, high humidity air is blown into the refrigerating chamber, the defrosting and heating time is shortened, so that when the system inside a single-system air cooled refrigerator enters into a defrosting period, the relative humidity average value is increased to 80 percent from 40 percent, and the fruit and vegetable fresh-keeping effect of the refrigerating chamber is improved greatly.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a defrosting and humidifying device for an air-cooled refrigerator and a control method thereof. Background technique [0002] Single-system air-cooled refrigerators occupy a large share of the air-cooled refrigerator market due to their high cost performance. The single-system air-cooled refrigerator also has the feature of automatic heating and defrosting. Its evaporator is located in the low-temperature freezing room, which is kept in a low-temperature state for a long time and has a strong dehumidification ability. Therefore, the average humidity of the refrigerating room is 25% and 40%. As a result, the fruits and vegetables stored in the refrigerator compartment of the single-system air-cooled refrigerator are easy to dry out, which is the biggest drawback of the single-system air-cooled refrigerator. In a single-system refrigerator, one or more relatively sealed and ind...
