Refrigerator with temperature varying and/or vacuum preservation system and control method thereof

Abstract

The invention relates to a refrigerator with a temperature varying and / or vacuum dual preservation system, which comprises a box body, a refrigerating chamber, a freezing chamber and a temperature varying chamber, wherein a vacuum preservation system is arranged on a temperature varying preservation drawer to form a storage space with temperature varying and vacuum dual preservation functions. The control method provided by the invention comprises the following steps of: selecting temperature varying and / or vacuum preservation functions; selecting temperature varying; inputting refrigeration; detecting a temperature control sensor, and closing an air door when the set temperature is reached; automatically starting a vacuum pump to vacuumize; detecting the pressure inside the preservation drawer, and stopping the operation of the vacuum pump when the set pressure is reached. By adopting the technical scheme, the preservation drawer with the temperature varying preservation and / or vacuum preservation dual functions on the refrigerator is realized, and the space is fully utilized; and users can select different low temperatures according to different foods, the autonomy of function selection by the users is increased, and the requirement of user individuation is satisfied.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a refrigerator with variable temperature and / or vacuum dual fresh-keeping system, and also relates to a control method for the refrigerator with variable temperature and / or vacuum dual fresh-keeping system. Background technique [0002] In the study of fresh-keeping technology, the main reason why fresh food is difficult to preserve for a long time is that the temperature of stored food will continue to rise, the humidity will increase, and the air pressure is conducive to the growth and reproduction of harmful bacteria. Kill or inhibit the survival of mold and fungus, can inhibit the respiration of stored fresh food (such as plants, meat), and prevent dehydration and mildew. [0003] The application of the existing technology is to separate the variable temperature space and the vacuum fresh-keeping space in two spaces. The variable temperature is used as a single functional area, and t...
