In the embodiment, the pressure received by the rubber diaphragm 8a is balanced by the spring 8c, and the mechanical displacement (Δ
A pressure sensing means 8 of a type that converts the signal I) into an electrical signal was used. The diaphragm 8a receives pressure, and the displacement phase (△X) of the diaphragm plate 8b is determined by the spring 8c.
d, and finally an electrical signal proportional to the pressure is obtained. A conceivable configuration of the mechanical-electrical converter 8d described in 1fX is such that the inductance of the winding changes with the amount of displacement of the displacement rod 8e made of a magnetic material.

る。In such a configuration, it is assumed that the difference between the water level in the bathtub 2 and the water level in the communication pipe 5 changes the air pressure in the air pocket 5a in the communication pipe 5, in the duplex 7, and in the pressure receiving chamber 8f of the pressure detection means 8. You can use it to raise the water level in the bath.
