。C) Problems to be Solved by the Invention By the way, in the water heater described above, when the water level in the water storage case decreases due to hot water being dispensed, the water supply device operates to supply new water to the water storage case. There was a concern that the hot water would mix with makeup water and the hot water temperature would drop. Of course, mixing of hot water and water can be prevented by providing a water supply guide device that guides make-up water from the water supply device to the bottom of the water storage case. However, when controlling the hot water temperature using a single temperature sensor, if the temperature sensor is located too high,
It is difficult to detect a drop in water temperature due to make-up water, and if the temperature sensor is located too low, it becomes difficult to detect the boiling of water, making accurate temperature control impossible.

湯を必要以上に沸上げる心配がない。The hot water in the Himuro (16) that was boiled in this way is
The hot water is sent from the hot water supply port (29) to the usage section by a pump (not shown). As a result, when the water level in the ice chamber (16) falls below the control water level of the pole tap (8), new water is supplied to the water chamber (16) from the water supply port (8A) of the pole tap (8).
will be replenished. Make-up water is guided below the water chamber (16) through the inside of the water supply guide device (9). In addition, since the water supply guide device (9) and the hot water supply port (29) are located far apart from each other, even if water is supplied during hot water dispensing, there is almost no mixing of hot water and the hot water in the upper part of the ice chamber (16) is discharged. It can be taken out without significantly lowering the temperature. In addition, the temperature sensor (
25) is provided in the water passage directly below the water supply guide device (9), so that a drop in water temperature due to make-up water can be quickly detected. For this reason, the control device (23)
The combustion device (18) can be activated by this, and hot water can be continuously tapped at a predetermined temperature while water is being supplied. In addition, the temperature sensor <25) is the heating device (10)
The combustion chamber case (11) is higher than the heat exchanger (12) of the
Since it is installed at a high position equivalent to the top plate of the ice room (
16) Boiling of the water at the top can be detected well,
You don't have to worry about boiling water more than necessary.
