A red wine preservation device and refrigeration and freezing device

Abstract

The invention discloses a fresh-preserving device for wine. The fresh-preserving device comprises a wine bottle retainer, a switch valve, a vacuum pump, a sliding part and a bottle plug, wherein the switch valve is arranged on the wine bottle retainer; the vacuum pump communicates with an air inlet of the switch valve through a pipeline, and a pressure sensor is arranged on the pipeline; the bottle plug is inserted into an opening of a wine bottle containing the to-be-preserved wine, and the bottle plug is provided with a vent hole; and the sliding part can slide up and down relative to the wine bottle retainer, the sliding part comprises a trigger portion which is used for triggering the switch valve to be opened or closed and an air conduction portion which is matched with the bottle plug to form a sealed air cavity, an air suction opening communicating with the vent hole is formed in the air conduction portion, and the air suction opening communicates with an air outlet of the switch valve through a pipeline. According to the fresh-preserving device for the wine, the problems that in the prior art, a fresh-preserving device is small in application range of wine bottle models, and the fresh-preserving treatment cannot be carried out while the wine bottle is placed are solved. The invention further discloses a refrigerating device comprising the fresh-preserving device for thewine.

Description

technical field [0001] The invention relates to the technical field of red wine storage, in particular to a vacuum-pumped red wine fresh-keeping device. Background technique [0002] With the improvement of people's quality of life, red wine is gradually popularized in ordinary families, and drinking red wine has also become a habit of many families. And for a bottle of 750ml red wine, after opening the bottle, it is difficult to drink it all at once, so if the remaining red wine after opening the bottle cannot be effectively kept fresh, it will easily cause the remaining red wine to deteriorate. For this reason, the traditional method is to increase refrigeration in the wine cabinet and store it at a low temperature, which can prolong the freshness to a certain extent, but the freshness period is very short, and the remaining red wine is over-oxidized by the oxygen in the air during storage. And the mouthfeel is obviously reduced, which greatly affects the experience of dr...

Problems solved by technology

[0004] 1. This solution requires the user to operate the control panel before starting the air pressure adjustment system for vacuuming and fresh-keeping. It cannot realize the automatic vacuuming function after the red wine bottle is placed on the device, and the degree of humanized design needs to be improved.

[0005] 2-In this solution, the red wine bottle is placed between the baffle plate 68 of the red wine fresh-keeping room and the bottom plate of the red wine bottle fixing device 64, and its height is fixed. Therefore, the selection range of the height of the red wine bottle is very small, and it can only be used for a certain model The red wine bottle is vacuumized, and the scope of application is very small
