Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to an energy supply device for household appliances. Background Art

[0002] Existing household electricity is generally powered by municipal electricity. Each household appliance will release a certain amount of energy during use. For example, when an electrical appliance is in use, the motor of the appliance will generate a large amount of heat, and this part of the heat cannot be used. For example, the evaporator of the air conditioner is installed indoors, and the condenser of the air conditioner is installed outdoors. When the air conditioner is cooling, the evaporator absorbs heat as an indoor heat exchanger, and the condenser releases heat as an outdoor heat exchanger, thereby completing the cooling of the air conditioner; when the air conditioner is heating, the evaporator releases heat as an indoor heat exchanger, and the condenser absorbs heat as an outdoor heat exchanger, thereby completing the heating of the air conditioner. During the cooling or heating process of the air conditioner, the condenser will release a large amount of heat energy or cold energy to the outside world. This part of the energy is directly discharged into the outside world, which not only wastes this part of the energy, but also causes a certain burden on the environment around the air conditioner.
