Title: Hot water/cool water mixing device
Inventor: NASU ICHIRO
IPC: F24D17/00
Filed: 1989-02-22
Abstract: PURPOSE:To attain the control of temperatures with high accuracy by computing the drive conditions of a mixing valve with input of the hot water supply state received from a hot water supply state detecting part, the temperature setting signal received from a temperature setting part, and the drive conditions of the mixing valve and outputting the obtained drive conditions of the mixing valve to a mixing valve driving part. CONSTITUTION:A temperature sensor 6 detects a sudden change of temperature of the supplied hot water which is caused when the supplied hot water has a low temperature and no temperature is set by a temperature setting part 9. Then the sensor 6 drives early a mixing valve 3 in the water opening side at a high speed in order to minimize the overshoot. Furthermore the temperature switch timing is finely controlled. That is, the sudden change control is sent when the detected temperature is sufficiently lower than a set level as long as the temperature changing rate is very large after addition of the temperature deviation to the control switching data. Then the detected temperature is set close to the set level if the temperature change is not so large. Thus the control is more optimized at the time of suddenly changing.
