Abstract

The invention provides a refrigerating and freezing device. The refrigerating and freezing device comprises a storage compartment, a cooling chamber, an air path system and a plurality of drawers, wherein the storage compartment is divided into a plurality of first spaces; the cooling chamber is configured to accommodate an evaporator of the refrigerating and freezing device; the air path system is provided with a plurality of first air supply outlets, a main return air inlet and an on-off control device; each drawer is mounted in one first space; each drawer is provided with an air inlet anda return air inlet; each air inlet is communicated with one first air supply outlet; each return air inlet is communicated with the main return air inlet; and the on-off control device is configured to control airflow from the cooling chamber to flow to one or more of the plurality of first air supply outlets, so that all or part of the airflow is controlled to flow to the corresponding drawer, the temperature in the corresponding drawer is controlled. According to the refrigerating and freezing device, independent temperature control of each drawer of a refrigeration compartment of a refrigerator is realized, so that an optimal storage environment area for different foods is achieved, and a user is guided to correctly place the optimal storage space for the foods.

Description

technical field

[0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device. Background technique

[0002] With the development of social economy and the improvement of people's living standards, refrigerators have also become an indispensable household appliance in people's daily life. Existing refrigerators have a uniform temperature control for the refrigerated compartments, each layer is set at a uniform temperature of 0-5°C, and the best storage temperature for all foods is different. If the user sets the temperature to the low range of 0°C, the temperature of the entire compartment of the refrigerator will be around 0°C. Food stored at an optimal temperature greater than 5°C will greatly shorten the food preservation period and accelerate food deterioration. Contents of the invention

[0003] In view of the above problems, an invention is proposed in order to provide a refrigerator and freezer...
