Control method of refrigerating and freezing device and refrigerating and freezing device

Abstract

The invention relates to a control method of a refrigerating and freezing device and the refrigerating and freezing device. The refrigerating and freezing device comprises a box body which defines a storage compartment. The control method comprises a refrigeration operation step, a food material judgment step and a cooling operation step. The refrigeration operation step is to control the temperature of the storage compartment to be within a first preset temperature range. The food material judgment step is to judge whether a new food material is placed in the storage compartment. The coolingoperation step is to reduce the temperature of the storage compartment if a new food material is placed into the storage compartment. Since the new food material is higher in temperature than an original food material in the refrigerating and freezing device, the temperature of the storage compartment is reduced, so that the storage temperature suitable for original food material storage in the storage compartment becomes suitable for the new food material, the preservation of the new food material is facilitated, the newly-placed food material is guaranteed to have good storage conditions, the storage effect of the original food material is not influenced, and the preservation effect of the refrigerating and freezing device on the food materials is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a method for controlling a refrigeration and freezing device and the refrigeration and freezing device. Background technique [0002] With the development of social economy and the improvement of people's living standards, refrigerators and freezers have become indispensable household appliances in people's daily life. [0003] At present, the temperature of the storage compartment of the refrigerating and freezing device will not change according to whether new ingredients are put into the storage compartment. , still keep the temperature of the storage compartment in the temperature range before putting in new food materials, this refrigerating and freezing device is not conducive to the preservation of new food materials. Contents of the invention [0004] In view of the above problems, the present invention is proposed to provide a control method of a refri...
