Refrigerator

Abstract

The invention belongs to the technical field of refrigerator equipment, provides a refrigerator and solves the technical problem that existing mobile refrigerators fail to keep the temperature for a long time after power cutoff. The refrigerator comprises a refrigerator body, an inner container with a cavity is arranged in the refrigerator body, the refrigerator body is provided with a heat insulation layer which is capable of peripherally coating the inner container, and a heat accumulation medium layer is detachably connected onto the inner wall of the inner container. A refrigeration sheet is arranged on the refrigerator body, the heat accumulation medium layer and the refrigeration sheet are positioned on inner and outer sides of the heat insulation layer respectively, the inner side of the refrigeration sheet is connected with the heat accumulation medium layer through a conduction medium capable of transferring thermal energy, and the outer side of the refrigeration sheet is fixedly connected with a heat radiation device communicated with the outside. The refrigerator has the advantage that refrigeration effects can be kept constantly for a long time owing to slowness in cold quantity release of the heat accumulation medium layer of the refrigerator.

Description

technical field [0001] The invention belongs to the technical field of refrigeration refrigerators, and relates to a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. A car refrigerator is a continuation of a household refrigerator, and generally has less noise and less pollution. When driving, you only need to insert the power plug into the cigarette lighter hole to cool down the refrigerator. There are mainly two kinds of car refrigerators on the market, one is semiconductor car refrigerator, its principle is to rely on electronic chips for cooling, and use P-N junctions composed of special semiconductor materials to form thermocouple pairs and produce Peltier effect, that is, through direct current refrigeration. A new type of refrigeration method, the refrigeration temperature range is 5°C to 65°C. The advantage of this type of refrigerator is that it can both cool and heat, and is environmen...

Problems solved by technology

[0004] The vehicle-mounted refrigerator provided by the above-mentioned patent uses a compressor to work. After the vehicle is parked, the engine is turned off and the power supply is stopped. The temperature in the refrigerator will rise rapidly, which will affect the effect. At the same time, the use of the compressor makes the refrigerator heavy, inconvenient to carry, high power consumption and expensive. expensive
