<P>PROBLEM TO BE SOLVED: To provide a hot water supply device capable of reducing risk of giving an uncomfortable feeling to a user. <P>SOLUTION: The hot water supply device 1 includes a first water supply pipe 51a, a first hot water delivery pipe 52a, a hot water supply mixing valve 54 for mixing water flowing in the first water supply pipe 51a and hot water flowing in the first hot water delivery pipe 52a, a first supply pipe 53a for flowing mixed water composed of water and hot water mixed in the hot water supply mixing valve 54 to a supply part, and a control device. The control device regulates the opening of the hot water supply mixing valve 54 so that when supply of mixed water to the supply part is stopped, a predetermined opening before supply of mixed water to the supply part is stopped is changed to a stop opening by which a ratio of water or hot water is larger than a mixing ratio between the water and hot water in the mixed water at the predetermined opening. Further, the control device, when supply of mixed water to the supply part is restarted, regulates the opening of the hot water mixing valve 54 so that the stopped opening is changed to the predetermined opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
