Claims

[Scope of utility model registration request]

a hot water tank having a first heating element in the lower part and a second heating element in the upper part, a water supply port in the lower part and a hot water outlet in the upper part; a solenoid valve provided in the water outlet part; a first heating element control thermostat that detects the water temperature near the heating element and turns off when the temperature exceeds a preset temperature;
A second heating element control thermometer that detects the water temperature near the heating element and turns off when the water temperature reaches the boiling point, and a second heating element control thermostat that is installed near the hot water outlet so that the temperature of the hot water discharged from the hot water outlet is suitable for sale. a first relay that responds to the suitable temperature thermostat; a self-maintaining first relay that is controlled via the second heating element control thermostat and the normally closed contact of the first relay; a fourth relay that is controlled and self-maintaining via the first heating element control thermostat and another normally closed contact of the first relay; the second heating element control thermostat and the fourth relay; a third relay controlled via the normally closed contacts of the four relays;
energization is controlled through a heating element control thermometer of the controller and a normally closed contact of the third relay, and the second heating element is energized through a normally open contact of the second heating element control thermometer and the third relay. A hot water supply control device for a vending machine, which controls energization and enables opening of the solenoid valve via a normally open contact of the first relay and a normally closed contact of the second relay. .
