The water outlet channel 5a and the air outlet channel 5b are set on the water-gas separation box 5, the water inlet of the water outlet channel 5a is arranged at the bottom of the water-gas separation box 5, and the air inlet of the air outlet channel 5b is arranged at the bottom of the water-gas separation box 5 cavities In the upper part, there is a certain distance at the top of the air inlet water-air separation box 5 of the air outlet passage 5b, so that the steam can be discharged from the water-air separation box 5 from the air inlet of the air outlet passage 5b; the water-air separation box 5 can flow here The boiling water is separated from water and air, effectively releasing the air resistance in the water outlet, so as to ensure smooth water outlet.

The correlation coefficient between the outlet water temperature of the above-mentioned water dispenser and the voltage of the water pump, the voltage of the grid, the temperature of the environment and the temperature of the heating plate is obtained through a combination of preset and automatic learning by the microprocessor. A method for controlling the temperature of an instant hot water dispenser without secondary pollution, comprising the following steps:

1) 4 preset values: a. Water outlet temperature, set to 80-90 degrees; b. Heater 9 maximum limit 95-98 degrees; c. When the water dispenser enters the automatic learning program, set the temperature of the heater 9 A value of 40 degrees, only when the actual temperature of the heater 9 is less than or equal to 40 degrees, the heater 9 will work; when the actual temperature of the heater 9 is higher than 40 degrees, the heater 9 will not work, and the water pump 7 will first Work, the temperature of the heater 9 is reduced by the water flow, and when the heater 9 is reduced to be equal to or less than 40 degrees, the heater 9 starts to work; d. when starting automatic learning, the voltage of the water pump 7 is 5 volts;

2) Put the bottled water on the bucket base 2, plug in the external power supply 10, and press the automatic learning button 9a;

3) Measure the temperature through the temperature sensor 8 installed at the water outlet of the heater 9. When the temperature of the heater 9 is equal to or lower than 40 degrees, the heater 9 starts to work, and the microprocessor starts to measure the grid voltage and ambient temperature;

4) When the temperature of the heater 9 reaches 40 degrees, the water dispenser starts to heat up and count, and records the time required for heating to 50 degrees, 60 degrees, 70 degrees, and 80 degrees respectively, and then calculates the thermal inertia of the water dispenser according to the fuzzy algorithm ;

Compared with the traditional water dispenser, each water dispenser can save electricity by at least 1000 degrees per year. The amount of boiled water per year for each water dispenser is calculated as 360 liters. No matter whether it is one-off or divided into countless times, the utility model has no secondary pollution and quick hot water dispenser, and only needs 90 degrees of electricity to boil 360 liters of water, while using a traditional water dispenser 1200 kWh electricity is required. There are two reasons why traditional water dispensers consume electricity. One is that the capacity of the heated water tank of traditional water dispensers is generally 1000 ml or about 5 cups of water. Consumers must boil all the water in the tank every time they take boiled water, no matter how much boiled water they actually need. Open, if only one cup of boiling water is actually needed, then the electricity required to boil the other 4 cups of water is wasted electricity, wasting 80% of the electricity; second, when the traditional water dispenser is in standby, it is always in the state of burning-stop- In the heating-stop cycle heating process, it is detected that the power consumption is 2 degrees per day, which is 730 degrees per year.

The above water dispenser, the shape of the bucket can be matched with the two buckets of the applicant’s utility model patent No. ZL201220541118.1 and ZL201220541169.4, and the inner surface of the bucket base 2 is arranged as an arc surface structure to play Guiding function, the bottom of the curved surface is 1-3mm higher than the top of the diversion column 3, and the barreled water can be automatically slid to the bucket base 2 after being turned upside down so that the hollow diversion column 3 can penetrate the bucket cover and fit firmly So far, there is no need to deliberately align the barrel cover with the hollow guide column. If the curvature of the inner arc of the bucket seat is not well designed and the depth of the indentation is not greater than the height of the hollow guide column, you must be very careful to align the bucket lid with the hollow guide column when filling the bucket of water, otherwise it will be installed incorrectly. All the pipelines of the water dispenser from the inside of the bucket to the water-air separation box are completely closed. Since no pollutants can enter the water path of the water dispenser, there is no need to clean it, thus ensuring that the drinking water can flow out in a fully enclosed state. Can effectively avoid secondary pollution.

Above-mentioned water dispenser, heater 9 does not store hot water, as long as normal temperature water flows through heater 9 by the flow rate of setting, just can boil water. When the control switch 6 is pressed to the cold water position, the water pump 7 starts to work, the heater 9 does not work, and the cold water flows out from the water-gas separation box 10; when the control switch 6 is pressed to the hot water position, the heater 9, the temperature sensor 8, the micro The processor 11 starts to work, and when the temperature of the heater 9 reaches the set value, generally it only takes 3 seconds for the water pump 7 to start working, and boiling water flows out from the water-gas separation box 5; when the control switch is pressed to the 0 position, the water dispenser All electrical appliances stop working. After the above-mentioned water dispenser is assembled, press the automatic learning in the microprocessor 11 when powering on the machine for the first time, and the microprocessor 11 computer software tests and collects water pump 7, heater 9, ambient temperature, The temperature sensor 8, the parameters related to the grid voltage and the outlet water temperature and speed are automatically stored, and this work is completed by the factory before leaving the factory. The user only needs to press the control switch 6 when using the water dispenser.

The above-mentioned water dispenser adjusts the water outlet speed of boiling water in real time through the water pump 7, thereby ensuring the accurate and stable temperature of the water outlet. Because the heating power of the water dispenser is fixed, but the ambient temperature and grid voltage of the water dispenser in use vary widely, if the flow of the water pump 7 is constant, the outlet water temperature will be unstable. The higher the grid voltage and ambient temperature, the higher the outlet water temperature, and vice versa. If it is higher than 100 degrees, it will spray steam, and if it is lower than 80 degrees, it will not be able to make tea. In order to ensure accurate and stable outlet water temperature, the water pump 7 must be able to adjust the flow of the water pump in real time according to the specific grid voltage and ambient temperature. The water dispenser adjusts the flow rate of the water pump 7 by adjusting the voltage of the water supply pump 7 in real time. The higher the voltage of the water supply pump 7 is, the greater the flow rate of the water pump 7 is, and vice versa.

The above-mentioned water dispenser is provided with a temperature sensor 8 at the water outlet of the heater 9. When the microprocessor 11 receives the information that the temperature is too high from the temperature sensor 8, the voltage of the water pump 7 will be increased to accelerate the water outlet speed. Processor 11 will reduce the voltage of water pump 7 and slow down the water outlet speed when processor 11 receives the information that the temperature is on the low side from temperature sensor 8.
