Fresh-keeping drawer, refrigerator with fresh-keeping drawer, and temperature and humidity control method

Abstract

The invention discloses a fresh-keeping drawer, a refrigerator with the fresh-keeping drawer, and a temperature and humidity control method. The fresh-keeping drawer comprises a drawer door, a drawer body, a cavity for containing the drawer body, and a drawer air duct device arranged on the cavity; and an anti-condensation air duct and a cooling air duct which are communicated with cold air are arranged in the drawer air duct device. The anti-condensation air duct passes through a moisture permeable membrane assembly which is arranged at the top of the cavity and is communicated with the interior of the cavity; and the anti-condensation air duct and the cooling air duct are respectively provided with an air door device. Through two cold air channels and the arranged air door devices, dehumidification and condensation prevention can be achieved, cooling is accelerated, and an air curtain is formed. Redundant water vapor in the drawer can be discharged through the moisture permeable membrane to avoid condensation; the heat exchange efficiency can be improved; and the temperature and humidity can be accurately controlled. When the drawer is opened, the air curtain can be formed above the drawer body to block air convection between the interior of the drawer and the external environment, so that temperature and humidity fluctuation in the drawer is reduced, and the purpose of keeping fresh is achieved.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a fresh-keeping drawer, a refrigerator with the drawer, and a method for controlling the temperature and humidity of the fresh-keeping drawer. Background technique [0002] The fruit and vegetable drawer is an important part of the freezer compartment of the refrigerator, and it is also the main area where the refrigerator performs the function of keeping fruits and vegetables fresh. Different from meat products, fresh plant-based ingredients such as fruits and vegetables are still "living" organisms during the storage period after picking, and their cells and tissues are still undergoing various metabolic reactions such as respiration and transpiration. Respiration and oxidation reactions will promote the aging of plant organisms, resulting in accelerated ripening, aging, and corruption of fruits and vegetables, and will also lead to the continuous consumption of various nutrients.
