Vacuum negative-pressure fresh-keeping cabinet

Abstract

The invention discloses a vacuum negative-pressure fresh-keeping cabinet which comprises a cabinet body, a closed ozone deodorizing dehumidifier, a vacuumizing device and a refrigerating device; a movable sealing door is mounted on the cabinet body; the closed ozone deodorizing dehumidifier is mounted at the top of the cabinet body and used for enabling oxygen in the cabinet body to react to generate ozone, and an ozone sensor is mounted in the cabinet body; the vacuumizing device comprises a vacuum diaphragm pump installed at the top of the cabinet body and a negative pressure sensor installed in the cabinet body, and the vacuum diaphragm pump is used for vacuumizing the interior of the cabinet body to form negative pressure; and the refrigerating device comprises a compressor and a condenser which are mounted at the top of the cabinet body. Stress at the two sides of a sealing door body is consistent, the danger of glass bursting caused by compressive deformation of the sealing doorbody is avoided, the drying degree of gas entering a sealing box body is guaranteed, the danger of discharging and power connection of a ceramic plate of the ozone generator when the environment humidity is high is avoided, normal work of the ozone generator is guaranteed, and the service life of the ozone generator is prolonged.

Description

Technical field: [0001] The invention relates to a vacuum negative pressure fresh-keeping cabinet. Background technique: [0002] In recent years, vacuum fresh-keeping cabinets have been used more and more. For example, the publication number is CN111588232A, and the name is a Chinese invention patent application for a smart cabinet for fruit and vegetable fresh-keeping in supermarkets. The vacuum device can evacuate the cabinet to form a negative pressure, and the storage time of fruits and vegetables can be prolonged under the vacuum environment. At the same time, it is also equipped with an ozone generator. The ozone generator can react the oxygen in the cabinet to generate ozone, which can sterilize fruits and vegetables, slow down the activity of bacteria inside the food, and prolong the preservation effect. [0003] However, in specific applications, due to the need to directly observe the specific conditions of the internal fruits and vegetables from the outside, the...

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, the present invention provides a vacuum negative pressure fresh-keeping cabinet, which solves the problem that one side of the sealed door is fixed by a loose leaf and the other side is a movable end, and avoids sealing both sides of the glass door when the cabinet is vacuumed. The situation of inconsistent force avoids the danger of pressure deformation of the sealed glass door and the risk of glass bursting, solves the problem of discharge and power connection of the ozone generator in the past when the humidity environment is high, and ensures the normal operation of the ozone generator. service life
