照）。However, in such a conventional hot and cold water supply device, when the flow rate to be supplied is set to a small amount, hot water reaching a sensor for measuring the temperature of hot and cold water mixed with hot and cold water is reached. Since the time is delayed and the amount of hot and cold water becomes small, the time taken for the sensor to detect the correct hot and cold water temperature becomes longer due to the influence of the heat capacity of the flow path in the middle and the sensor itself than when the flow rate is high. (See the graph at the bottom of Figure 4). Therefore, if the set temperature is changed when the flow rate to be supplied is small, the response of the sensor that feeds back is delayed and the drive amount of the mixing valve becomes too large. However, there is a problem that the temperature of the hot water supplied immediately after the setting becomes considerably higher than the set temperature or becomes lower than the set temperature, and the deviation of the temperature becomes larger as the temperature difference after changing the setting becomes larger ( (See the graph at the top of FIG. 4).
