There are many water dispenser products on the market. Different types of water dispenser products have certain differences in the process of drinking water refrigeration and heating.
Water dispensers water supply structure
There is a water convergence device for drinking water equipment, and the outlet of the micro electric pump is connected to the water inlet of the water outlet through a pipeline with a pipeline.The single outlet connected to the entire water dispenser, the pipe diameter of the water outlet outlet outlet of the water outlet is greater than the diameter of the water inlet.There is also a single air inlet. This ventilation port is connected to the normal temperature water tank through the pipeline.Below the water surface of the water dispenser to facilitate the arrangement of the overall structure of the water dispenser.
Hot and cold water dispenser
1. Straight cold and cold water dispenser provides room temperature water from the water tank. There are two ways to enter the water: enter the cold bile container all the way to the cold water; enter the hot pot on the other side and heat the hot water after heating.
2. After pressing the refrigeration switch, the AC voltage is lowered through the power transformer, the rectifier diode is made of full -wave rectification, and the capacitor filtering, the output DC voltage is out of the semiconductor refrigeration component refrigeration and fan exhaust. At the same time, the refrigeration indicator lights light up.Because the straight cold and cold water dispenser does not have an automatic temperature control, the refrigeration indicator is often on after turning on.
3. Press the heating switch, the heating indicator is bright, the electric heating pipe is heated, the water temperature in the heat tank rises, the setting temperature, the thermostat contact is cut off, the heating indicator is off, the heating indicator is extinguished, the electric heating pipe stops stopheating.The water temperature drops to the set temperature, the temperature controller contacts closed, the heating power is automatically connected, the heating indicator lights, and the electric heating pipe is heated.Repeat the above process later so that the water temperature keeps constant temperature between 85-95 ° C.
Warm water dispenser
1. Press the heating switch. The power supply provides a power supply for the thermal insulation indicator, and the power instructions are provided.All the way to constitute the heating circuit, so that the electric heating pipe is heated and heated; the other way provides voltage heating instructions for the heating indicator.
2. The water in the hot tank is heated to the set temperature, the thermostat contact is broken, the heating is cut off, the heating indicator circuit power is off, the heating indicator light is extinguished, and the electric heating pipe stops heating.
3. The water temperature drops to the set temperature, the temperature controller contacts connect the power circuit, and the electric heating tube will be re-fever. In this way, keep the water temperature between 85-95 ° C.
The warm -drinking water circuit uses dual protection elements. When the water dispenser is over -temperature or a short -circuit failure occurs, the ultra -temperature condenser automatically melts or the manual reset temperature controller is automatically disconnected to the heating circuit power supply, which plays a protective role.The ultra -temperature conservator is a disposable thermal protection element, which cannot be reset. After the failure is excluded, replace the new ultra -temperature conardor according to the original specifications, and then press the manual reset the temperature controller of the retention button with your hand.Essence
Compressed refrigerated water dispenser
Cooling principle
1. Press the refrigeration switch, connect the power supply, the cooling green indicator lights, and the compressor starts to start operation.
2. The compressor absorbs the steam of the heat -absorbing gas in the evaporator, compressed into high temperature, high -pressure gases, and send it to the condenser.
3. The refrigerant steam is coagulated into a high -pressure liquid to heat dissipation through the condenser.Then use the capillary to reduce the voltage and inflow into the evaporator, absorb the warm water and electricity heat of the cold gallbladder, reduce the water temperature, and the refrigerant liquid is sucked back by the compressor. This continuously circulates and truly achieves cooling purposes.
4. When the water temperature drops to the set temperature over time, the contact temperature controllers contact is broken, the cooling green indicator goes off, the compressor stops, and the heat preservation state is transferred.
5. After the power is disconnected, the water temperature gradually rises. When the setting temperature is risen, the contact thermostat contact movement is closed, the green indicator light is turned on, and the compressor runs.In this cycle, the water temperature is controlled between 4-12 ° C.
Heating principle
Water dispenser
1. Press the heat -making switch, connect the power supply, connect the heating circuit, lighten the red heating indicator, and heat the electric pipe.
2. The water temperature reaches the set temperature, automatically reset the temperature controller to automatically cut off the power, the red heating indicator is extinguished, and the heat preservation state is turned.
3. After the power is disconnected, the water temperature gradually decreases to the set temperature. The thermostat contact movement is closed, the power supply is turned on, the red heating indicator is on, the electric heating pipe is heated again, and the water temperature of the water dispenser is controlled at 85-95 ° C.between.
The compressed refrigerated water dispenser uses a temperature control device with temperature. When the circuit appears overheating, the protective device will automatically melt or disconnect the circuit when the protection device is overloaded to play a safe protection role.
