Multifunctional ventilating and freshness retaining refrigerator

Abstract

The invention discloses a multifunctional ventilating and freshness retaining refrigerator. Ventilation and freshness retaining of the refrigerator are necessary. The quality of air in the refrigerator can be visually known through a display screen; by a ventilation indicator lamp and a defrosting indicator lamp, ventilation, deodorization and defrosting of the refrigerator can be carried out by a user conveniently in time; an air feeding tube is in sleeving connection with an air discharging tube, so that the temperature can be changed conveniently; and owing to the multifunctional refrigerator, the user feels comfortable in the daily life.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a multifunctional refrigerator for ventilating and keeping fresh. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. Humans have understood from a very early age that food stored at lower temperatures is less prone to spoilage.

Problems solved by technology

The more things are placed in the refrigerator, the more miscellaneous it is, and the smell will be bigger and more unpleasant, which will cause the food in the entire refrigerator to deteriorate and be polluted, and the air quality in the refrigerator will decrease after long-term use, and the freezer will frost and other problems , although the user will regularly perform ventilation, defrosting and other work, but the refrigerator will be overloaded during the period, which will cause a drop in air quality and even affect other foods, not only causing food to deteriorate, but also It will be more expensive

[0004] Therefore, it is necessary to provide a ventilation and fresh-keeping multi-functional refrigerator to solve the problem of electricity consumption caused by defrosting and the failure of timely ventilation in the refrigerator in the prior art.
