[0029] The purpose is to convert heat energy into electric energy by using the Seebeck effect of the thermoelectric converter 4. The working mechanism of the Seebeck effect is that if one end of an electric circuit composed of two different materials is heated and the other end is kept at low temperature, electrons will migrate from the high-temperature zone to the low-temperature zone, thereby establishing a potential difference between the two ends, and generating an electric current.
[0030] In use, cold water passes through the cold water inlet pipe 301, so that the outer wall surface of the cold water inlet pipe 301 is relatively low in temperature, and hot water passes through the hot water inlet pipe 302, so that the outer wall surface of the hot water inlet pipe 302 is relatively high in temperature. One side of the hot water inlet pipe 302 is in abutment with the hot end heat-conducting fin 401, and one side of the cold water inlet pipe 301 is in abutment with the cold end heat-dissipating fin 402. Electrons migrate from the hot end heat-conducting fin 401 to the cold end heat-dissipating fin 402, so that a potential difference is established between the two ends, and an electric current is generated. The thermoelectric module transmits the electric energy generated by the electric current to the lithium battery 5, so that the thermal energy is conveniently converted into electric energy, and energy is saved.

The purpose is to conveniently increase the contact area of the cold and hot water pipes 3 with the hot end heat-conducting fin 401 and the cold end heat-dissipating fin 402 by providing the arc-shaped concave surface 404 matched with the outer wall surface of the cold and hot water pipes 3, and to improve the thermal energy conduction effect.
[0034] In order to conveniently improve the automation degree, preferably, the lithium battery 5 is fixed to the inner side of the cabinet body 1, and a radar distance sensor 7 is electrically connected to the front side of the lithium battery 5. The purpose is that the radar distance sensor 7 detects whether there is a human body in front of the bathroom cabinet in real time. When the radar distance sensor 7 detects that there is a human body in front of the bathroom cabinet in real time, the lithium battery 5 is fed back to control the power supply to the LED lamp strip 6, so that the LED lamp strip 6 is lit. When the radar distance sensor 7 detects that there is no human body in front of the bathroom cabinet in real time, the lithium battery 5 is fed back to control the power supply, so that the LED lamp strip 6 is extinguished. The user does not need to turn on and off the LED lamp strip 6 every time, and the automation degree is improved.
[0035] In order to facilitate the user to wash hands, wash face, brush teeth and other daily hygiene functions, in the embodiment, preferably, the top of the cabinet 1 is provided with a slate table 8, the front side of the faucet 2 is provided with an over-the-table basin 9, and the over-the-table basin 9 and the faucet 2 are both fixed on the slate table 8.
[0036] In order to facilitate the improvement of the aesthetic degree, in the embodiment, preferably, the front side of the slate table 8 is provided with a table edge 10, the table edge 10 protrudes from the cabinet 1, and the lower side thereof abuts against the LED lamp strip 6, and the purpose is to shield and hide the LED lamp strip 6 through the table edge 10, thereby improving the aesthetic degree.
