Second outlet opens that to carry out coffee brewed, and after the completion of coffee is brewed, air pump starts.
There is dry combustion method to prevent i.e. hot heater, Flow-rate adjustment pump working is first started after above-mentioned purifying drinking appliance is powered
For a period of time, make to be full of water in pipeline.
The water shortage in pure water tank is illustrated when lower limit switch is triggered, it is heat that should now be controlled by master control borad
Heater is forbidden operating to ensure that safety.Illustrate that the water in pure water tank has reached maximum when upper limit switch is triggered
Capacity, should now forbid being intake to pure water tank, for example, by master control borad water cleaning systems can be controlled to stop pure water, or net
Then the entering water electromagnetic valve that goes out in pure water pipeline to increase of water system controls entering water electromagnetic valve to disconnect water route to stop by master control borad
Go out pure water.
The heating of i.e. hot heater needs a period of time, so this control method is by by i.e. hot heater
The temperature of the water after heating is slightly less than input temperature values n*Ts or is slightly less than preset temperature value n*Ty with one and carries out with one
Compare, as T2 >=n*Ts or T2 >=n*Ty, the running status of water temperature change and i.e. hot heater in loop is more steady
It is fixed, the regulation of flow velocity is now just carried out, the adjustable range of Flow-rate adjustment water pump is reduced, make leaving water temperature more accurate, while also
Electric energy can be saved, now One In and Two Out magnetic valve is closed, the water after heating enters condensation by the first non-return valve
It is back in pure water tank after box.As T2 >=Ts or T2 >=Ty, then open One In and Two Out magnetic valve and export accordingly, it is ensured that
Leaving water temperature is at or above the temperature value or preset temperature value of input, and due to there is Flow-rate adjustment testing pump flow
Leaving water temperature can be made too high.By this control method above-mentioned purifying drinking appliance of control leaving water temperature can be made more accurate, controlled
Method processed is simply conducive to the stable operation of system in itself.After the completion of coffee is brewed, booster air pump is residual in coffee brewing device
The hot water for staying thoroughly blows out, and prevents residual water soup to hinder user.
The utility model mainly has the advantages that compared with prior art：Hot water can more accurately be controlled out
Temperature, flow passage structure is simple, with low cost, with the device such as water purification and coffee, enriches the function of product, meets and uses
Various demands at family, can also effectively prevent the i.e. hot too high gasification dry combustion method of heater temperature, and extension is making for hot heater
Use the life-span.

Amount has reached maximum capacity, now controls osmosis filtration formula water cleaning systems 4 to stop water purification by master control borad 91.
The heating of i.e. hot heater 33 needs a period of time, so the control method of the present embodiment is by by i.e.
The temperature of the water after the heating of hot heater 33 is slightly less than input temperature values n*Ts or is slightly less than default temperature with one with one
Angle value n*Ty is compared, as T2 >=n*Ts or T2 >=n*Ty, the change of water temperature in loop and i.e. hot heater 33
Running status is more stable, now just carries out the regulation of flow velocity, reduces the adjustable range of Flow-rate adjustment water pump 31, makes leaving water temperature
More accurate, while electric energy can also be saved, now One In and Two Out magnetic valve 37 is closed, and the water after heating is by the
One non-return valve 13 is back in pure water tank 1 after entering condensation box 14.As T2 >=Ts or T2 >=Ty, then One In and Two Out is opened
Magnetic valve 37 is exported accordingly, it is ensured that leaving water temperature is at or above the temperature value or preset temperature value being input into, Er Qieyou
In there is Flow-rate adjustment water pump 31 to adjust flow leaving water temperature can be made too high.This is controlled by the control method of the present embodiment
The purifying drinking appliance of embodiment can make leaving water temperature more accurate, and control method is simply conducive to the stable operation of system in itself.Coffee
After the completion of coffee is brewed, booster air pump 54 can thoroughly blow out the hot water of residual in coffee brewing device 52, prevent residual water soup
Hinder user.
Two specific embodiments of the present utility model are these are only, but design concept of the present utility model is not limited to
This, the insubstantial modifications that all utilization the utility model designs are made to the utility model each fall within protection of the present utility model
Within the scope of.
