Moreover, the set device 30 monitors a DC voltage Vdd rectified by the rectifying circuit 30B by a voltage monitoring circuit 30H. When an excess magnetic field is applied from the outside part to a communication coil 4, a voltage obtained by dividing the DC voltage Vdd is made higher than a reference voltage Vref, and a comparator 30H2 switches a high voltage detection signal S1 to an on signal. Thus, a high voltage protecting gate 30G is interrupted, and an LED5 is turned off.

Title: Hot water feeding device
Inventor: OKADA SADAO
IPC: F24H1/46
Filed: 1990-07-26
Abstract: PURPOSE:To perform a fast feeding of hot water into a bath tub and reduce a water flowing sound by a method wherein a valve body of a three-way valve has the first position, the second position and the third position, respectively and at the second position, an opening area against the second pipe passage is set smaller than opening areas for the first pipe passage and a hot water feeding circuit. CONSTITUTION:At the first position, a ball valve body 46 is communicated with only a hot water feeding pipe 16 in respect to a forward pipe passage 30a. At the second position, the hot water feeding pipe 16 and an inverse direction pipe passage 30b are communicated to each other in respect to the forward direction pipe passage 30a. At the third position, the forward direction pipe passage 30a and the inverse direction pipe passage 30b are communicated to each other. At the second position, an opening area of a small communication port 46b in respect to the inverse direction pipe passage 30b is small in respect to a normal opened communication port 46a and the first communication port 46c, resulting in that the hot water supplied from the hot water feeding pipe 16 has a low resistance in the forward direction pipe passage 30a, and inturn it shows a high resistance at the inverse direction pipe passage 30. Since the forward direction pipe passage 30a is provided with a pump 31 and a bath heat exchanger 32, there is no difference in resistance in each of the pipe passages and further the hot water is properly branched and supplied to the bath tub B, resulting in that a flow rate of fed hot water can be increased.
