Composite energy refrigerator

Abstract

The invention discloses a composite energy refrigerator. A solar panel and one or more wind power or manpower self-generation units are arranged outside the refrigerator. The output end of the self-generation unit is parallelly connected with the input end of a storage output circuit through a one-way isolation circuit. The input end of an automatic control circuit is connected with the input end of the storage output circuit, a relay is used for controlling the self-generation unit to automatically transfer alternating current utility power to the refrigerator when the voltage is too low so as to supply power, and the alternating current power can be automatically transferred to the self-generation unit when the self-generation unit is fully charged so as to supply power to the refrigerator, so that the daily consumption of the utility power is extremely little. The composite energy refrigerator solve the problems that a traditional self-generating refrigerator which purely uses solar energy and the like is affected by the climate, the power supply is often interrupted, the temperature of the refrigerator goes up and the food is thawed, so that the refrigerator which uses green energy really has practical social value, and the total cost of the solar refrigerator can be greatly reduced. The invention is used for home refrigerators which produce green energy, and can provide green power for other electric appliances.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a composite energy refrigerator. Background technique [0002] Energy saving, environmental protection, green and low carbon in all walks of life have become the common goal pursued by people in the world today. Refrigerators are the most widely owned electrical appliances in the society. Although the electric power is not very large, the accumulated power consumption is still large because they are connected to the mains all the year round. The power supply that the electric refrigerator of people's family adopts is 220V alternating current mains at present, does not also utilize renewable energy such as solar energy, wind energy as energy source. Since the required input power of the refrigerator is only more than 100 watts, it is feasible to use solar energy and wind energy as energy sources in terms of the required power. However, solar energy and wind energy are easily affected by weather...

AI Technical Summary

Problems solved by technology

However, solar energy and wind energy are easily affected by weather conditions. Using solar energy or wind energy alone as the energy source of refrigerators often causes energy interruptions in certain days, which limits the practical application of solar or wind energy refrigerators. Kaiping Port Electricity, Guangdong Province The Chinese patent No. 201020191531.0 of Electric Appliance Co., Ltd., which is entitled "a solar refrigerator", discloses a solar refrigerator, but this patent does not overcome the above-mentioned defects, making it difficult to really enter the market; Power generation as a supplementary energy source for refrigerators has the dual advantages of exercising, energy saving and environmental protection, and is not affected by the weather, but no one has yet proposed
