The stored hot water is fed from the bottom of the tank to the heater by the action of the hot water circulation pump, where it is heated and heated. A thermistor detects the hot water temperature after heating, compares it with a set hot water temperature, and controls the rotation speed of the hot water circulation pump so that the hot water temperature at the outlet of the heater becomes equal to the set value. On the other hand, the flow rate sensor measures the amount of hot water heated and heated by the heater, and when the set amount of hot water is measured, the power supply to the heater and hot water circulation pump is cut off.

れている。■ is a tank that stores hot water. A water supply port 2 and a hot water supply port 3 are fixed to the tank l, and the water supply port 2
A water supply pipe 4 is connected to the water supply pipe 4, and a pressure reducing valve 5 and a water stop valve 6 are attached to the water supply pipe 4. Further, a safety valve 7 is attached to the hot water supply port 3. 8 is a hot water circulation pump, 9 is a heater, and 10 is a flow rate sensor, which are connected in sequence to form a hot water heating circuit. The inflow pipe 11 of the hot water heating circuit is connected to the bottom of the tank 1, and the outflow pipe 12 is connected to the top of the tank 1, respectively. Reference numeral 13 denotes a thermistor for detecting the temperature of hot water, which is installed in a conduit connecting the heater 9 and the flow rate sensor 10. 14 is a controller, which includes the hot water circulation pump 8, the heater 9, and the flow rate sensor 10.
, are electrically connected to the hot water temperature detection thermistor 13 and the operating section 15. The operation unit 15 is provided with a boiling water temperature setting switch and a boiling water amount setting switch (not shown).

熱ヒータ9への送水量をコントロールするのである。The electric water heater of this embodiment is controlled by the operating unit 15 based on the boiling water temperature and hot water volume setting values. That is, when the operation is started, the hot water circulation pump 8 and the heater 9 are energized, and the hot water stored in the tank 1 is heated through the inflow pipe 11 and sent to the heater 9 to raise its temperature. The hot water temperature after heating is detected by the hot water temperature detection thermistor 13, compared with the set hot water temperature by the controller 14, and the rotation speed of the hot water circulation pump 8 is adjusted so that the hot water temperature at the outlet of the heater 9 becomes equal to the set value. The amount of water fed to the heater 9 is controlled.

電を遮断することによって行なわれるのである。The hot water heated to the set temperature in this way passes through the flow rate sensor lO1 outflow pipe 12, and then flows from the top of the tank 1 into the tank 1.
It can be stored back. On the other hand, the amount of boiling water is controlled by the operation section 1.
This is done by cutting off the power to the hot water circulation pump 8 and heater 9 when the flow rate sensor IO detects the amount of hot water preset in step 5.
