Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to an energy utilization 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.

[0071] More specifically, the first electrical conductor 301 and the second electrical conductor 302 are both metal conductors. The first electrical conductor 301 and the second electrical conductor 302 are not only heat-conducting but also electrically conductive. They can be conductors made of metal materials such as copper or iron. For example, the first electrical conductor 301 is a copper wire and the second electrical conductor 302 is an iron wire. The first connector of the first electrical conductor 301 and the second electrical conductor 302 is disposed on the cold source energy storage device 201. The first connector of the first electrical conductor 301 and the second electrical conductor 302 directly exchanges heat with the cold source energy storage device 201, thereby making the first electrical conductor 301 and the second electrical conductor 302 heat-conducting. The first connector of the first electric conductor 301 and the second electric conductor 302 is in a relatively low temperature environment to form a low temperature connector 303, for example, 5°C-20°C; the second connector of the first electric conductor 301 and the second electric conductor 302 is arranged on the heat source energy storage device 202, and the second connector of the first electric conductor 301 and the second electric conductor 302 directly exchanges heat with the heat source energy storage device 202, so that the second connector of the first electric conductor 301 and the second electric conductor 302 is in a relatively high temperature environment to form a high temperature connector 304, for example, 40°C-80°C, so that there is a temperature difference between the low temperature connector 303 and the high temperature connector 304.

[0072] It is understandable that as long as there is a temperature difference between the low temperature connector 303 and the high temperature connector 304 , temperature difference power generation can be achieved, which essentially utilizes the Seebeck effect. How to utilize the Seebeck effect to generate electricity is an existing technology and will not be elaborated here.

[0073] Specifically, by controlling the temperature difference between the low-temperature connector 303 and the high-temperature connector 304, power can be supplied to household appliances of different powers. In some application scenarios, night lights, induction lights, mobile phones, etc. can be supplied. In some application scenarios, exhaust fans, dehumidifiers, fans, etc. can be supplied. This not only recovers excess heat, but also provides clean energy for household appliances.

[0074] In other embodiments, the thermoelectric power generation component 30 may also use semiconductors to form an electrical circuit, such as P-type semiconductors and N-type semiconductors. How to form the electrical circuit depends on the actual application scenario.

[0075] In the embodiment of the utility model, the temperature difference power generation component 30 includes at least one power socket, which is electrically connected to each household appliance through the power socket, and the temperature difference power generation component 30 supplies power to each household appliance; each household appliance connected to the power socket of the temperature difference power generation component 30 is a load 100.

[0076] Example 2

[0077] See also Figure 5In the embodiment of the utility model, different from Embodiment 1, the first external heat exchange tube 501 and the second external heat exchange tube 502 are both connected to the same water tank 70, the third external heat exchange tube 503 and the fourth external heat exchange tube 504 are both connected to another water tank 70, and the first external heat exchange tube 501, the second external heat exchange tube 502, the third external heat exchange tube 503 and the fourth external heat exchange tube 504 are each provided with a switch valve 80.

[0078] In this way, the first external heat exchange component 50 and the second external heat exchange component 50 can be managed separately, storing energy first and then releasing energy after the energy storage is completed, thereby avoiding confusion in energy storage and release of the cold source energy storage device 201 and the heat source energy storage device 202.

[0079] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
