PURPOSE: A hot water supply device using water as a heating element is provided to automatically turn on/off a switch depending on the operation of an opening and closing valve. CONSTITUTION: A hot water supply device using water as a heating element comprises a conductive pipe(11), a terminal(15), an inlet pipe(18), a drain pipe(19), an opening and closing valve(30), and a switch(50). The conductive pipe is made of a conductive material. Water is stored or flows inside the conductive pipe. When the switch is turned on, the terminal conducts electricity to the conductive pipe through the water. The inlet pipe supplies water to the inside the conductive pipe. The drain pipe discharges the water to the outside the conductive pipe. The opening and closing valve is installed in the inlet pipe or the drain pipe. |
