A refrigerator that keeps freshness and purifies air sustainably

Abstract

The invention relates to a refrigerator with the functions of continuous freshness-preservation and air purification. The refrigerator comprises a refrigerator cabinet which is internally provided with an air return device and connected with an air purification device. A first air outlet and a second air outlet are formed in the air purification device. A first solenoid valve is arranged on the first air outlet and communicates with the air return device through a first pipeline; a second solenoid valve is arranged on the second air outlet and communicates with the exterior of the air purification device; the first solenoid valve and the second solenoid valve are electrically connected with a controller; and the controller controls the first solenoid valve and the second solenoid valve to open and close correspondingly. According to the refrigerator with the functions of continuous freshness-preservation and air purification, the air purification device is arranged on the refrigerator cabinet, air flowing direction is controlled by controlling the air purification device through the controller, and the function that not only can air in the refrigerator cabinet be purified, but also the indoor environment can be purified is achieved.

Description

technical field [0001] The invention relates to the technical field of refrigerator equipment, in particular to a refrigerator that can sustainably keep fresh and purify air. Background technique [0002] With the improvement of people's living standards and the acceleration of people's life rhythm, refrigerators have become a must-have product for every family. Many families purchase food for a few days or a week at a time, and then put them all in the refrigerator. Then take it as you need it, which seems to save time, but the problem is: either the fresh vegetables you bought are lost, or the food smells, or even eat spoiled food and eat up your stomach. In fact, the refrigerator is not a universal way to keep food fresh. Cabinet, fresh food such as vegetables, especially green vegetables, are prone to produce ethylene gas and dehydration in low temperature environment, meat or fish products are easy to rot and produce fishy or rotten smell, some bacteria even in low temp...

However, ultraviolet radiation affects the health of users, and ozone can easily cause plastic aging in refrigerators.

The activated carbon adsorption method generally puts the activated carbon in a breathable package and puts it into the storage compartment of the refrigerator. The activated carbon installed in this way has low adsorption efficiency, occupies the storage space of the refrigerator, and affects the appearance of the refrigerator.
