Problems solved by technology

[0002] The temperature of traditional air-cooled refrigerators fluctuates greatly due to factors such as working logic and defrosting; especially during defrosting, it will affect the freshness of ingredients and lead to the loss of nutrients
At present, some refrigerators add a sealing cover to the drawer of the freezer, but because there are air outlets and return air outlets on the drawer, it is not strictly sealed. During the cooling and heating process of the refrigerator freezer, the temperature inside the drawer The temperature is basically the same as the temperature outside the drawer, and the fluctuation of temperature difference has not been greatly improved

Abstract

A refrigerator (100) comprises: a drawer (3) arranged in a refrigerating chamber (2), a cover (4) used to open or close the drawer (3); a driving mechanism (5) used to drive the cover (4) to move along a front-back direction in relation to the drawer (3); and a controller. In the embodiment, the driving mechanism (5) drives a movement of the cover (3) to control a temperature inside the drawer (3).

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with a constant temperature freezing drawer and a control method thereof. Background technique [0002] The temperature of traditional air-cooled refrigerators fluctuates greatly due to factors such as working logic and defrosting; especially during defrosting, it will affect the freshness of ingredients and cause the loss of nutrients. At present, some refrigerators add a sealing cover to the drawer of the freezer, but because there are air outlets and return air outlets on the drawer, it is not strictly sealed. During the cooling and heating process of the refrigerator freezer, the temperature inside the drawer The temperature is basically the same as the temperature outside the drawer, and the fluctuation of temperature difference has not been greatly improved. [0003] In view of the above problems, it is necessary to provide a refrigerator and its control method to solve the...
