technical field

The invention relates to the technical field of refrigerators, in particular to a refrigerator.

Background technique

At present, most of the refrigerator doors on the market are ordinary foam doors. Ordinary foam doors cannot see the contents clearly when the door is not opened. You must open the refrigerator door to see it. The cold air in the refrigerator is locked, resulting in the loss of cold air and wasting energy.

Then, a transparent glass refrigerator door without a light-transmitting film appeared later. Although the transparent glass refrigerator door can see the internal items from the outside, it is easy to damage the integrity of the appearance. It looks disorganized, goes against the design trend of kitchen appliances, and does not meet the aesthetic needs of modern people. In addition, since the transparent glass refrigerator door is not equipped with an induction system (such as voice-activated induction, light-activated induction, infrared induction, etc.), the lights in the refrigerator box will only light up after the refrigerator door is opened, and the items in the refrigerator can be seen clearly. It will also lead to the loss of cold air in the refrigerator, wasting energy, and it is impossible to realize the simplification, humanization and intelligence of the home environment.

Based on the above, there is an urgent need for a refrigerator that solves the problem of poor overall appearance of existing refrigerator doors, failure to meet the aesthetic needs of modern people, easy loss of air-conditioning, waste of energy, and inability to achieve simplicity, humanization and harmony in the home environment.
