Hot water principle of water dispenserWhen the water dispenser water added, we will draw water. Then the hot water in the hot water will gradually decrease in the process of fetching water.The question is: will it lead to cold water flowing into the hot water because of the water in the hot water? If the cold water gets into the hot water, then the hot water we drink isn't half hot and half cold? If this is not the principle, what is the principle? More detail, if you have a better anatomy
Yes, that's the principle. As the cold water flows in and the water temperature drops, the water is heated automatically!
When the water heater is over temperature or has short circuit fault, the overtemperature protector is automatically fused or manually reset, and the temperature controller automatically disconnects the heating circuit power supply to 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, contacts can start work again. ?"Semiconductor direct cooling water dispenser.Semiconductor 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. ?Refrigeration press switch, 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 lights. Since the direct cooling hot and cold water dispenser is not equipped with automatic temperature control, the cooling indicator lamp is always on when the power is turned on.
Warm type drinking machine.Warm type drinking machine, press the switch for power supply heating, insulation indicator provides power, as power indicator. At the same time, the power supply is divided into two paths: a heating circuit is formed; the electric heating tube is electrified and the temperature is raised; the other way is a heating indicator; the voltage is supplied as a heating indicator. When the water in the hot pot is heated to the set temperature, the temperature controller contacts are disconnected, the heating and heating indicating loop power supply is cut off, and the heating indicator lamp is extinguished, and the electric heating tube is stopped to heat. ?When the water temperature drops to the set temperature, the thermostat connected power supply circuit, electric heating tube to heat, so the cycle to keep the water temperature at 85-95 DEG C.
The heating switch is pressed, the heating indicator is bright, the electric heating tube is heated, and the water in the hot pot is heated up. When the water temperature is known to set the temperature, the temperature controller contacts are disconnected, the heating power is automatically cut off, the heating indicator is turned off, and the electric heating tube is stopped heating. When the water temperature drops to the setting temperature, the temperature controller contacts are closed, the heating power supply is automatically connected, the heating indicator is bright, and the electric heating tube is heated. The process is repeated so that the water temperature remains constant between 85-95 degrees centigrade."Compression refrigeration drinking machine.When you press the compression refrigeration water dispenser refrigeration refrigeration switch, the green light will start running, the compressor, the refrigerant vapor in the evaporator is endothermic gasification sucked back, and then compressed into high temperature and high pressure gas, sent to the condenser, heat condenses to a high pressure liquid in the outside air through the condenser, and then by capillary blood flowing into the evaporator, absorption heat and cold chamber the temperature dropped, then being sucked back into the compressor. This cycle, to achieve the purpose of cooling. When the water temperature drops to the set temperature with time, the contact point of the refrigeration temperature controller is switched off, the refrigeration green indicator lamp goes out, the compressor stops and transfers to the thermal insulation condition. After the power failure, the water temperature rises gradually. When the temperature rises to the set temperature, the contact of the refrigerating thermostat is closed, the power supply is switched on, the green indicator light is on, and the compressor runs. In this way, the water temperature is controlled between 4-12 degrees centigrade.
