17に接続されている。A water level sensor is composed of the diaphragm 13 facing the suction passage in the adapter body and the fixed electrode 15 opposed to the movable electrode 14 connected to the diaphragm 13, and is composed of the movable electrode 14 and the fixed electrode 15. A radio frequency transmitter 17 having a resonance circuit with a capacitance 16 is provided, and the output of the transmitter 17 is connected to an antenna 19. Further, a liquid level switch 18 composed of a pair of electrodes 18a and 18b is provided facing the bathtub water.

の湯が抜かれると自動的に電波の発信が停止する。With the above configuration, when hot water supply is started from the water heater main body 4 through the hot water supply pipe 10, the diaphragm 13 is displaced by receiving the water pressure of the bathtub water, the distance between the movable electrode 14 and the fixed electrode 15 is reduced, and the static electricity , The frequency of the transmitter 17 becomes lower. The power control circuit 20 detects the continuity of the liquid level switch 18 and supplies the power of the battery 21 to the transmitter 17 if there is continuity. Hot water is supplied from the water heater to the bathtub, and the water level is turned on.
, The power control circuit 20 is off and no radio wave is transmitted. When the level of the water rises and the electrode switch 18 is immersed in the water, the output of the power control circuit 20 is turned on, and a radio wave modulated by the water level signal is transmitted. Further, when the bathing is completed and the hot water in the bathtub is drained, the transmission of the radio wave stops automatically.

寿命が永くなる。In this way, there is no need for a connection cord between the water level sensor provided on the adapter and the water heater, which simplifies installation work and allows the water level sensor to be sealed inside the adapter. It is also excellent. In the power control circuit, radio waves are transmitted only when the bathtub water level is equal to or higher than a certain value according to the signal of the liquid level switch 18, so that the life of the battery 21 is prolonged.
