Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The electric cooker proposed according to embodiments of the present invention and its control method and control device are described with reference to the accompanying drawings.
Fig. 1 is the flow chart of the control method of electric cooker according to the ... of the embodiment of the present invention, as shown in Figure 1, the control method
Including：
S1 obtains the last boiling temperature cooked.
In one embodiment of the invention, record what the maximum temperature of kettle temperature when this is cooked was cooked as this
Boiling temperature uses when being controlled in order to cook next time.For example, passing through the temperature sensor sense being arranged among rice cooker upper cover
Survey kettle temperature, by the upper cover temperature sensor senses for process of entirely cooking to maximum temperature store, using as cooking
Boiling temperature.
S2, the temperature range belonging to boiling temperature determine initial heating power, switching heating power and stop temperature
Degree, wherein initial heating power is more than switching heating power.
It is understood that for certain areas, for example, highlands, since topography is relatively high, air pressure is relatively low, because
And boiling point reduces when cooking, and computer heating control is carried out with the heating parameters of factory setting, often there is a problem of that rice is half-cooked.Change sentence
It talks about, boiling temperature is influenced by electric cooker using local air pressure height, if all using for different boiling temperatures
The computer heating control parameter of factory's setting carries out computer heating control, often occurs overflowing or half-cooked problem.
So in an embodiment of the present invention, obtaining the last boiling temperature cooked, the temperature belonging to boiling temperature
Range is spent, computer heating control parameter is adjusted, i.e., suitable computer heating control parameter is selected according to the boiling temperature that locality has,
It is thus possible to avoid the occurrence of spilling or half-cooked problem.It should be noted that electric cooker can be preserved belonging to boiling temperature
The mapping table of temperature range-initial heating power-switching heating power-stopping temperature.
S3, the heating module for controlling electric cooker are heated with initial heating power.
S4, when the kettle temperature of electric cooker reaches switching temperature, control heating module is added with switching heating power
Heat, wherein switching heating power is less than initial heating power, to avoid there is spillover.Until the cooker body temperature of electric cooker
Reach stopping temperature, control heating module stops heating, to avoid dryouting.For example, installed by the cooker body lower part of electric cooker
Temperature sensor senses cooking bottom temperature.
The control method of the electric cooker of the embodiment of the present invention, by reference to the boiling temperature that the last time cooks, according to upper one
Temperature range belonging to the secondary boiling temperature cooked determines initial heating power, switching heating power and stopping temperature, in other words,
According to electric cooker using local concrete condition adjust automatically computer heating control parameter, it is thus possible to avoid the occurrence of spilling or dryout
The problem of, improve effect of cooking.
For convenience of description, N1 is the Power Regulation ratio of initial heating power when being cooked using initial heating pattern, and Power Regulation ratio is
Ratio in period in heating time/period, that is, a cycle shared by heating module heating time；N2 is to be added using initial
Switch the Power Regulation ratio of heating power when heat pattern is cooked, T4 is stopping temperature when cooking using initial heating pattern, and n1, n2 divide
Not Wei Power Regulation than correction value, t0, t1 are temperature corrected value.Wherein, initial heating pattern can be understood as user and newly buy electric meal
It is first to use or initially several times in use, electric cooker is heated with the initial heating pattern after pot.
For example, after cooking every time, number of cooking is recorded, that is, the number that will cook after cooking increases by 1.The present invention's
In embodiment, when number of cooking is less than preset times, for example, when number of cooking is less than 5 times, it is believed that electric cooker is new.Control
Heating module processed is heated with initial heating pattern.Specifically, control heating module is heated with Power Regulation ratio N1, when electric meal
When the kettle temperature of pot reaches such as T1 DEG C of initially handing over temperature, control heating module is heated with Power Regulation ratio N2, until electricity
The cooker body temperature of rice cooker reaches initial and stops temperature T4.
In one embodiment of the invention, the value range of N1 is 12/16-16/16, and the value range of N2 is 4/16-
8/16, the value range of initially handing over temperature is 80-90 DEG C, and the value range of T4 is 120-130 DEG C, and the value of parameters can
To be set as the case may be.For example, when electric cooker starts to cook, if it is determined that number of cooking is not up to 5 times, then control
Heating module is heated with Power Regulation ratio N1 such as 4/16, is always heated to upper cover temperature and is reached 85 DEG C, control heating module with
Power Regulation ratio N2 such as 6/16 is heated, and the bottom temp for being heated to cooker body reaches such as 125 DEG C of T4, terminates to cook.It will be entire
The maximum temperature of the upper cover sensor detection for process of cooking is recorded in the memory of chip, and the number that will cook increases by 1.
If number of cooking is more than preset times, according to above-mentioned control process, the boiling temperature cooked according to the last time
Determine this computer heating control parameter to carry out computer heating control.
Wherein, when boiling temperature is more than the first temperature threshold, illustrate that boiling temperature is relatively high, it can be fast with higher-wattage
Speed heating determines that the Power Regulation ratio of initial heating power is N1+n1, and the Power Regulation ratio for switching heating power is N2+n1, determines and stops temperature
Degree is T4-t0, to avoid dryouting；Alternatively, when boiling temperature is less than the first temperature threshold and is more than second temperature threshold value, it is believed that
Boiling point is not high, in order to avoid being boiling over, it is determined that the Power Regulation ratio of initial heating power is N1-n1, switches the tune of heating power
Work(ratio is N2-n1, and stopping temperature is T4+t0；Alternatively, when boiling temperature is less than second temperature threshold value, it is believed that boiling point is relatively low,
In order to avoid being boiling over, determining that the Power Regulation ratio of initial heating power is N1-n2, the Power Regulation ratio for switching heating power is N2-n2,
Stopping temperature is T4+t1.
In some embodiments of the invention, the value range of the first temperature threshold is 96-99 DEG C, and the value range of n1 is
, switching temperature T-T3, wherein T is the last boiling temperature cooked, and the value range of T3 is 3-5 DEG C, t0
Value range be 3-5 DEG C, the value range of second temperature threshold value is 90-92 DEG C, and the value range of n2 is 2/16-3/16, t1
Value range be 5-7 DEG C, the value of parameters can be set as the case may be.
