operational principle

1. Water tank and water channel: The raw water tank is filled with water. The float causes the inlet valve to close as the water level rises. Float switch action. Heating with an electric heating tube, boiling water is pressurized into the water storage tank by steam after boiling.

When the boiling storage tank is full of water, the float moves and the constant temperature electric heating tube works. Maintain a supply of hot water for drinking. When the water level in the raw water tank drops and the float ball drops, the inlet valve opens to add water and repeat the circulation process. Cycle back and forth to ensure the normal supply of boiling water.

2. Electric heater control circuit: Connected, the main circuit is powered on. The LED light is on. When the water level of the raw water tank reaches the set water level. The water level control switch is closed. The coil of contactor KM1 is energized. The main contact is closed, the heating tube is electrically heated, and boiling water enters the water storage tank. If the water storage capacity is insufficient, the insulation electric heating tube will work slightly. If the water storage capacity reaches the set value, it will act.

Will is connected to the contact. The coil of contactor KMl is powered off and reset, and the main contact disconnects the power supply of EHl-EH3 heating tube.

Abort heating. At this point. The coil of contactor KM2 is energized, and the contact of KM2 is closed. EH4 is powered on and put into insulation. During the insulation process, the temperature of the boiled water is controlled by the temperature control switch sTl for water output and ST2. When the set temperature is lower than sTl and ST2. The temperature control switch is actively powered on and heated; If the temperature exceeds the set value, the temperature control switches STT and ST2 will automatically cut off power and stop heating.

When the water tank is short of water, the water level switch actively cuts off the power supply to ensure that the heater is cut off immediately in case of no water or insufficient water. When the reserve of boiled water is insufficient. The water level switch is also actively disconnected, and the insulation heating tube does not participate in heating. For the Rejuvenation button.
