What does "ice fountain" and "hot ice" mean?
Semiconductor direct cooling type hot and cold water dispenserSemiconductor direct cooling type drinking water machine in use, direct cooling type water dispenser with tepid water from the water tank, the water is divided into two lines: one way into the cold container, after cooling cold water; another way into the hot pot, heated by hot water.Press the switch after cooling, AC voltage by the power transformer step-down, rectifier diode for full wave rectifier and capacitance filter, the output DC voltage for the semiconductor refrigeration component cooling and exhaust fans, at the same time, the refrigeration indicator light. Due to the direct cooling water dispenser with automatic temperature control, so after the start of refrigeration indicator bright.Press the heating switch, heating lamp, electric heating tube heating, hot water heating tank. When the water temperature to the set temperature, the thermostat contacts disconnect, automatically cut off the heating power, heating indicator lights and electric heating tube heating is stopped. When the water temperature drops to the set temperature, the thermostat switch, automatic through heating power, heating lamp, electric heating tube heating. Then repeat the above process, the water temperature keeps constant temperature at 85-95 degrees.
Moving off the heating circuit power supply, play a protective role. Over temperature fuse is a one-time thermal protection element can not be reset, etc. after troubleshooting change over temperature fuse new according to specifications of the original model, and then hand to press the reset button manual reset thermostat, contact closure can work again.
Hot water dispenserWarm type drinking machine, press the switch for power supply heating, insulation indicator provides power, electricity for instructions. At the same time, the power supply is divided into two parts: one way to form a heating loop, the heating tube heating temperature; the other way to provide voltage heating instructions for heating when the heat lamp. The water tank is heated to the set temperature, the thermostat contacts disconnect, cut off the heating and heating power indicating circuit, heating indicator lights, electric heating tube heating is stopped.When the water temperature drops to the setting temperature, the temperature controller contacts the power circuit, and the electric heating tube re heating, so that the water temperature is kept between 85-95 DEG C.
