Temperature self-adaptive bathtub

[0023] as attached figure 1 The shown temperature adaptive bathtub includes a bathtub body and a temperature adaptive device arranged inside the bathtub body.

[0024] Temperature adaptive devices include:

[0025] Located in the center of the tub body, the temperature sensing element is in direct contact with the surface of the tub body that is in contact with the water. It is used to measure the water temperature in real time when the tub body is in contact with the water; In contact with water, the water temperature data can be obtained more accurately;

[0026] The thermoelectric device is arranged on the side of the tub body close to the surface of the tub that is in contact with the water, and is used to directly convert thermal energy into electrical energy when needed, and directly convert electrical energy into thermal energy at another moment; the thermoelectric device is placed in the same The location close to the water can minimize the energy loss in the process...

[0039] In another embodiment, the controller can also be connected to one or both of the thermoelectric rectifier and the piezoelectric rectifier, and control electronic switching tubes such as mosfet through pwm to realize controllable rectification, and further target the output of the thermoelectric device and the piezoelectric device. The characteristics of electric power are used to improve the power quality output by the rectifier, so as to ensure the safety and reliability of the working environment of the capacitor.

[0040] The capacitor bank and storage battery bank can be a plurality of capacitors and storage batteries connected in series, a plurality of capacitors and storage batteries connected in parallel, and a plurality of capacitors and storage batteries connected in series and parallel, so as to meet the requirements of the output power quality.

[0042] This embodiment provides another temperature-adaptive bathtub, including a bathtub body and a temperature-adaptive device arranged inside the bathtub body;

[0043] Temperature adaptive devices include:

[0044] Located in the center of the bathtub body, the temperature sensing element is in direct contact with the surface of the bathtub body in contact with the water. When the bathtub body is in contact with the water, it is used to measure the water temperature in real time.

[0045] The thermoelectric device is arranged in the body of the bathtub near the surface of the bathtub that is in contact with water, and is used to directly convert thermal energy into electrical energy when needed, and directly convert electrical energy into thermal energy at another moment;

[0046] A thermoelectric rectifier, connected to the thermoelectric device, is used to rectify the power output by the thermoelectric device;

[0047] The piezoelectric device is arranged on the side of...
