Abstract

PURPOSE:To decrease the over-shoot of a mixed hot water temperature by operating hot water quantity to be mixed and water quantity, controlling a hot water adjusting valve driving device and a water adjusting valve driving device and controlling the water adjusting valve driving device so that the water quantity can be prescribed quantity, which is larger than an operated value, in the initial time of hot water temperature rising when hot water is started to be outputted. CONSTITUTION:While the hot water is normally fed, hot water quantity (QH) and water quantity (Qc) are operated based on set mixed hot water temperature (Ts), set mixing hot water quantity (Qs), a detected hot water temperature (TH) and a water temperature (Tc). When the hot water is started to be outputted from a natural cooling condition, for example, it is detected that difference between a detected hot water temperature TM and the water temperature Tc is smaller than a prescribed value and the water quantity Qc is controlled to be prescribed quantity (Qco) which is larger than the operated value. Namely, since the hot water temperature (TH) is low at the initial time when the hot water is started to be outputted, the QH=Qs and Qc=0 is obtained in the operation. However, the water quantity at a certain degree is obtained from the beginning in advance as Qc=Qco. Thus, the control delay of water quantity increase is canceled when the hot water temperature rises later and the over- shoot of the mixed hot water temperature is decreased.

(Problem to be Solved by the Invention) In this type of conventional device, the mixed water temperature is detected and the hot water amount and amount are changed so that the set mixed water temperature is achieved.
At the start of hot water dispensing, the m temperature is low due to natural cooling of the hot water side piping, so it takes time for the mixed water temperature to rise to the set mixing temperature of 11 m.
During this time, the hot water regulating valve is driven in the opening direction and the water regulating valve is driven in the closing direction, and the hot water regulating valve may be fully open and the water regulating valve may be fully open. Then, when the water temperature rises and exceeds the set mixed water temperature, the hot water control valve is driven in the closing direction and the water control valve is driven in the open direction, but since they start from fully open and fully open, respectively, they are controlled to the appropriate opening degree. There was an interlayer point that caused a large overshoot in the mixing temperature.
