Air cooling refrigerator and control method thereof

Abstract

The invention discloses an air cooling refrigerator which comprises a refrigerator body, a refrigeration system, a freezing air duct and a control system, wherein an evaporator chamber and a compartment serving as a freezing chamber are defined in the refrigerator body; the compartment comprises a first space with a sealed drawer and a second space located outside the drawer; the drawer is provided with an accommodating cavity for storing food and a ventilating opening for communicating the accommodating cavity with the outside of the drawer; the refrigeration system comprises an evaporator which is arranged in the evaporator chamber and forms cold air in the evaporator chamber through heat exchange; the freezing air duct comprises a first air supply duct for communicating the evaporator chamber with the second space, and a second air supply duct which is seamlessly connected to the ventilating opening and communicates the evaporator chamber with the accommodating cavity; and the control system is used for controlling one of the first air supply duct and the second air supply duct to be opened. Compared with the prior art, the air cooling refrigerator disclosed by the invention has the beneficial effects of low cold loss, small temperature fluctuation, relatively low water loss and good food freshness retaining effect.

Description

technical field [0001] The invention relates to an air-cooled refrigerator and a control method thereof, belonging to the technical field of household appliances. Background technique [0002] Refrigerator is a common household appliance used to store various foods. With the improvement of the quality of life, people not only have higher and higher requirements for the performance of refrigerators, but also have higher and higher requirements for refrigerator drawers, especially for the freshness preservation performance of refrigerator drawers. There are also increasing demands. For example, since different foods have different humidity storage requirements, in order to meet these requirements, airtight drawers are added in some refrigerators. [0003] However, the current refrigerators with sealed drawers have the following problems: on the one hand, drawers with simple structures have poor airtightness, and drawers with high airtightness require complex structures to sup...
