Abstract

The invention discloses a refrigerator with a vacuum packaging device. According to the refrigerator, the vacuum packaging device comprises a vacuum cavity, a vacuumizing device, a control system anda sealing heating device, the control system is connected to the vacuum cavity, the vacuumizing device and the sealing heating device respectively, the vacuumizing device is connected to the vacuum cavity, the sealing heating device is connected to the vacuum cavity, the vacuum cavity comprises an upper vacuum cavity body, a lower vacuum cavity body and a driving device, after the control system receives a vacuumizing instruction issued by a user, the driving device drives the upper vacuum cavity body and the lower vacuum cavity body to move relatively under the control of the control system till the upper vacuum cavity body and the lower vacuum cavity body clamp a seal of a storage bag, the vacuumizing device vacuumizes the vacuum cavity, and when the vacuumizing device determines that the pressure in the vacuum cavity meets a preset condition, the sealing heating device performs heating plastic sealing on the storage bag. The refrigerator has the advantages that the vacuumizing device is automatically controlled by the control system to vacuumize the vacuum cavity, so that the storage bag in the refrigerator can be automatically vacuumized.

Description

technical field [0001] The technical field of refrigerators according to the embodiments of the present invention, in particular, relates to a refrigerator with a vacuum packaging device. Background technique [0002] Fresh-keeping technology is a technology that has been focused on and developed by the refrigeration industry in recent years. From the perspective of technical classification, it can be mainly divided into the control of temperature, humidity, gas and microorganisms related to food materials, among which the research on temperature and humidity is more in-depth. In recent years, gas conditioning technology has gradually spread from the food production industry to the home appliance industry. Its main purpose is to inhibit the self-breathing of food and the respiration of microorganisms and bacteria, so the control technology of oxygen has become an important measure. The most direct and convenient way to reduce oxygen concentration is vacuum technology, so v...
