Stop heating；Controlling the fluid temperature in the liner between the temperature upper limit and the temperature upper limit.
In embodiments of the present invention, after powering on, microprocessor unit can detect water in liner by temperature detecting unit
Initial temperature T0.If initial temperature T0 is lower than temperature upper limit value, when such as 40 DEG C, microprocessor unit can be added by liner
Thermal control units control liner heating unit is heated, and the water temperature T 0 in liner is made to rise to 40 DEG C, then keep the temperature 40~
55℃。
In embodiments of the present invention, if microprocessor unit by liner temperature detecting unit detect in liner just
When beginning water temperature T 0 is higher than 55 DEG C, liner heat control unit can control liner heating unit and stop heating, and water temperature is allowed to drop naturally
Temperature.When water temperature is reduced to 40~55 DEG C, then keep the temperature at 40~55 DEG C.
In embodiments of the present invention, the initial temperature T0 that water in liner can be improved by the example scheme, by this article

Embodiment nine
The embodiment gives the operating voltage and heating power Ps of fast heat apparatus on the basis of above-mentioned any embodiment
Embodiment and flow rate of liquid value range embodiment.
In embodiments of the present invention, the operating voltage (such as voltage rating) of fast heat apparatus can satisfy: 220V and 220V with
Under, heating power Ps (such as rated power) can be no more than 2100W, that is, be less than or equal to 2100W.
In embodiments of the present invention, electric water bottle primarily directed to household, the rated power of fast heat apparatus is excessive, can lead
It sends a telegraph and flows through greatly, after carrying out above-mentioned restriction, can effectively limit electric current, prevent from leading to domestic power supply line mistake because electric current is excessive
Heat, and there are the safety problems such as on fire.
Optionally, the flow velocity for the liquid that the liquid pump is pumped out can satisfy: 400ml/min-2L/min.
In embodiments of the present invention, during speed heat, the flow velocity of water can be defined, the flow velocity of water can satisfy >=
400ml/min。
In embodiments of the present invention, water pump control unit can be according to the preset value of microprocessor unit, to control water pump
Flow velocity, so that control flows through the water velocity of fast heat apparatus.
In embodiments of the present invention, for example, the nominal flow rate of water pump can be 2L/min, water pump is controlled using PWM.
In general, water pump voltage is higher, the speed of water pumping is faster；Operating voltage is lower, and the speed of water pumping is slower.By controlling plugman
The duty ratio of work adjusts the operating voltage of water pump, to reach adjusting water velocity.For example, when duty ratio is 50%, water pump
Mean flow rate be about 1L/min.If water velocity is lower, water pump duty ratio with regard to smaller, get over by the time of water pump rotation
It is short.
In embodiments of the present invention, by above-mentioned analysis it is found that water velocity is smaller, the time of water pump rotation work is got over
Short, the thrust of water is with regard to smaller at this time.When the flow velocity of water is low, fast heat apparatus can quickly be heated water.Water velocity
When too low, fast heat apparatus may heat water to boiling quickly, and when boiling, due to the presence of steam, resistance is just bigger；And
Pump rotary speed is low at this time, water can not be pumped out, and so recycles, and will lead to fast heat apparatus and generates a large amount of steam, and water pumps out
Existing blockage problem.It when serious, or even will appear fast heat apparatus dry combustion method problem, lead to security risk.
