Should the pet water fountain be left on all the time?
Warm water fountain When the warm water fountain is in use, press the heating switch, and the power supply will provide power for the "keep warm" indicator light as a power-on indication. At the same time, the power supply is divided into two circuits: one circuit constitutes a heating circuit, which makes the electric heating tube energized to heat up; the other circuit provides voltage for the "heating" indicator light for heating indication. When the water in the hot tank is heated to the set temperature, the contact of the thermostat is disconnected, the power supply of the heating and heating indication loop is cut off, the "heating" indicator light goes out, and the electric heating tube stops heating. When the water temperature drops to the set temperature, the thermostat contacts are connected to the power circuit, and the electric heating tube reheats, so that the water temperature is kept between 85-95 °C over and over again. There are double protection elements in the circuit of the warm water dispenser. When the water dispenser is over-temperature or short-circuit fault occurs, the over-temperature fuse will automatically melt or the thermostat will be manually reset to automatically disconnect the heating circuit power supply to play a protective role. The over-temperature fuse is a one-time thermal protection element, which cannot be reset. After troubleshooting, replace the new over-temperature fuse according to the original model and specifications, and then manually press the reset button of the manual reset thermostat, and the contact can be closed to restart.
When the semiconductor direct-cooling hot and cold water dispenser is in use, the direct-cooling hot and cold water dispenser provides room temperature water from the water tank, and enters the water in two ways: one way enters the cold bladder container, and the cold water is refrigerated; the other way enters Hot tank, heated to produce hot water. After pressing the cooling switch under the water dispenser, the AC voltage is stepped down by the power transformer, full-wave rectified by the rectifier diode and filtered by the capacitor, and then the DC voltage is output for the cooling of the semiconductor refrigeration component and the exhaust of the fan. At the same time, the cooling indicator light is on. Since the direct-cooled hot and cold water dispenser does not have automatic temperature control, the cooling indicator light is always on after it is turned on. Press the heating switch, the heating indicator lights up, the electric heating tube heats up, and the water in the hot tank heats up. When the water temperature rises to the specified temperature, the contact of the thermostat is disconnected, the heating power is automatically cut off, the heating indicator light goes out, and the electric heating tube stops heating. When the water temperature drops to the required temperature, the contact of the thermostat is closed, the heating power is automatically connected, the heating indicator light is on, and the electric heating tube heats up. Then repeat the above process to keep the water temperature constant between 85-95°C. Compression type refrigeration water dispenser When pressing the refrigeration switch of the compression type refrigeration water dispenser, the cooling green indicator light is on, the compressor starts to run, and the refrigerant vapor that has absorbed heat and gasified in the evaporator is sucked back, and then compressed into high temperature and high pressure. The gas is sent to the condenser, dissipated to the outside air through the condenser and condensed into a high-pressure liquid, and then flowed into the evaporator through the capillary throttling and pressure reduction, absorbing the heat of the cold gallbladder and reducing the water temperature, and then being sucked back by the compressor. This cycle, to achieve the purpose of cooling. When the water temperature drops to the set temperature over time, the contact of the refrigeration thermostat is disconnected, the green indicator light for refrigeration goes out, the compressor stops, and it enters the heat preservation condition.
After the power is cut off, the water temperature gradually rises. When the temperature rises to the set temperature, the contact of the refrigeration thermostat is closed, the green indicator light is on when the power is turned on, and the compressor is running. In this cycle, the water temperature is controlled between 4-12 °C. Press the heating switch, the heating circuit is turned on, the red heating indicator lights up, and the electric heating tube heats up. When the temperature reaches our specified temperature, the thermostat will automatically reset, cut off the power supply, and the red heating indicator will go out, and it will turn to the heat preservation working condition. After the power is cut off, the water temperature gradually drops. When the temperature drops to the set temperature, the contact of the thermostat closes, the power is turned on, the red heating indicator lights up, and the electric heating tube heats up again. In this cycle, the water temperature is controlled between 85-95 °C. The fuse, the thermal fuse and the manual reset thermostat in this type of water dispenser are protection devices. When the circuit is overheated or overloaded, it automatically fuses or disconnects the circuit, which plays a role in safety protection.
