Problems solved by technology

In actual use, if the user needs to temporarily take out the fresh-keeping box to observe, check, and find the fresh-keeping food, fruits and vegetables, at this time, the fresh-keeping box will definitely lose its vacuum state
In addition, due to the need to install solenoid valves in the pipelines, the pipeline system and its control are complicated. The manufacture, installation, maintenance, and repair of solenoid valves also increase the manufacturing costs and operating costs of vacuum fresh-keeping refrigerators. On the contrary, reliability Not necessarily a corresponding increase

Abstract

The invention discloses a vacuum preserving refrigerator which includes special preserving box and sucking disc. They are connected with each other by suction nozzle in which check valve structure is set. The sucking disc is connected with evacuation device. The pipeline connected with the vacuum pump in the vacuum preserving refrigerator will not take up storing area, deform and loosen caused by collision. Even the suction nozzle is separated from the sucking disc which can not make the preserving box lose vacuum state.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator with a vacuum preservation function. Background technique [0002] Vacuum preservation is to put food or fruits and vegetables in a sealed container, and pump the container into a state close to vacuum, so that the air content or oxygen content in the container is greatly reduced, and the reproduction of various microorganisms that cause food or fruits and vegetables to rot and deteriorate is greatly inhibited. , The volatile ripening gas inside the fruit and vegetable or in the storage container is greatly reduced, so that the food or fruit and vegetable can be kept fresh. Vacuum fresh-keeping refrigerator is the application of vacuum fresh-keeping technology in refrigerators. [0003] The website of the State Intellectual Property Office of China has disclosed a utility model patent with the patent number: 00203007 and the name: "Vacuum Fresh-keeping Refrigerator". This patent ...
