When the inventors tried to add a mist heating function to a general hot water supply function using a water heater, when the mist heating operation was simultaneously performed during the hot water supply operation, the mist was ejected. Also, the temperature of the mist becomes the hot water supply set temperature, so that there is a problem that unless the hot water supply operation itself is performed at a high temperature, the heating effect by the mist cannot be substantially obtained. This is because mist heating requires the ejection of mist at about 80 ° C, and below that, the heating effect cannot be expected much.

According to the feature of the present invention, when simultaneous operation of hot water supply and mist heating is performed, high temperature water of a certain temperature is discharged from the heat exchanger to the hot water pipe by the control unit, and the high temperature water is discharged. A part of the mist flows into the mist heating pipe, and is sprayed from the mist nozzle at the end. On the other hand, the high-temperature water that has flowed without branching the tapping pipe to the mist heating pipe side is temperature-controlled by water from the mixing pipe that is adjusted and supplied by the control unit, and becomes hot water at the set hot-water supply temperature to supply hot water. Provided. When only mist heating is operated, of course, constant high-temperature water is supplied from the heat exchanger. Also in the case of the hot water supply operation alone, the above-mentioned constant high-temperature water is supplied, and the hot water supply set temperature is adjusted by the water from the water mixing pipe. However, of course, in the case of hot water supply alone, hot water at the set hot water supply temperature may be discharged from the heat exchanger from the beginning.

An example of the control of the water heater by the control unit 90 is as follows.
A case where the mist heating operation and the hot water supply operation are performed simultaneously will be described with reference to the flowchart of FIG. now,
The hot water supply operation is carried out and the remote control 10 is turned on by opening the unillustrated curan of the general hot water supply pipe 60 or turning on the automatic bath water supply operation switch of the remote controllers 100 and 110.
0 mist heating operation switch is on (S
1) Yes, the mist heating pipe by the control unit 90
The solenoid on-off valve 41 is opened (S2), and the heat exchanger 20 is opened.
The amount of combustion of the burner 21 is adjusted so that the hot water from the furnace becomes hot water of 80 ° C. (S3). Adjustment of the combustion amount of the burner 21 is performed by the control unit 90 calculating the required heat quantity from the incoming water temperature by the incoming water temperature sensor 12, the predetermined constant hot water outlet temperature of 80 ° C. and the incoming water amount by the incoming water flow rate sensor 11, The fuel supply can be controlled by controlling a fuel supply regulator (not shown) to the burner 21 so that the amount of fuel to be supplied is controlled. As a result, the water from the water inlet pipe 10 is heated by the heat exchanger 20 to high-temperature water at 80 ° C., and is discharged to the hot water outlet pipe 30. Then, a part thereof branches and flows into the mist heating pipe 40 and is sprayed from the mist nozzle 42 as a high-temperature mist. The heating by spraying the high-temperature mist can be performed, for example, on a bathroom.

The callan of the general hot water supply pipe 60 is closed,
And when the mist heating operation switch is turned on while the bath automatic hot water supply operation switch is off, that is,
Even in the case of the mist heating operation alone, the control unit 90 controls the combustion amount of the burner 21 so that the electromagnetic on-off valve 41 of the mist heating pipe 40 is opened and the hot water from the heat exchanger 20 is a high-temperature hot water of 80 ° C. Adjust Of course, hot water does not flow through the tap water pipe 30, the general hot water supply pipe 60, and the automatic bath water supply pipe 70 downstream of the branch point of the mist heating pipe 40, so that no water flows through the water mixing pipe 50, and the flow control valve 51 Is also not adjusted. On the other hand, when the mist heating operation switch is in the off state, the callan of the general hot water supply pipe 60 is opened,
When the bath automatic hot water supply operation switch is turned on, similarly, the control unit 90 adjusts the combustion amount of the burner 21 so that the hot water from the heat exchanger 20 becomes hot water at 80 ° C. The flow control valve 51 is adjusted to adjust the set hot water supply temperature. But,
In the case of this hot water supply operation alone, software of the control unit 90 may be set up so that hot water at the set hot water supply temperature is discharged from the heat exchanger 20 from the beginning.
