Description
Technical Field
The invention relates to the field of cooking, in particular to an electric cooker and a heating control method for the same.
Background
The housing of an electric cooker generally has two types, one is a metal housing and the other is a plastic housing. During the heating process of the electric cooker, the metal shell transfers heat faster, which makes it necessary to configure different heating programs for electric cookers with shells of different materials.
Taking the IH rice cooker as an example, for a product with a metal casing, the coil panel uses a scheme of more bottom windings and less side windings. For products with plastic shells, the coil panel adopts the scheme that the bottom winding is less and the side winding is more, so that rice can be cooked more conveniently, and the rice can be prevented from caking due to the excessive bottom winding. Different heating procedures are needed according to different shell materials and different winding modes.

Fig. 1 shows a flow diagram of a heating control method for an electric cooker. As shown in fig. 1, an embodiment of the present invention provides a heating control method for an electric cooking device, such as an IH rice cooker, which may include the following steps:
and step S110, controlling a heating device of the electric cooker to heat in a preset heating mode.
After receiving the starting instruction, the heating device is controlled to heat in a preset heating mode.
Here, the predetermined heating pattern may be that the heating device heats with a predetermined power and a predetermined power, but the embodiment of the present invention is not limited to this, and the predetermined heating pattern may also be that the heating device heats continuously with a certain predetermined power, and the value of the predetermined power may be set according to actual situations.
Step S120, judging whether the heating time t1 of the heating device of the electric cooker reaches the preset time t 0.
For example, a timer may be provided, and after receiving the start command, the heating device runs simultaneously with the timer, and the timer counts the heating time t1 of the heating device in real time.
In case that the heating time t1 does not reach the preset time t0 (i.e., t1< t0), the method continues to step S110, and controls the heating device of the electric cooker to heat at the first power ratio and the first power.
In the case that the heating time t1 does not reach the preset time t0 (i.e., t1 ≧ t0), steps S130 and S140 are executed.
And step S130, calculating a temperature rise value of a specific position of an inner pot of the electric cooker from the beginning of heating to the time when the heating time reaches the preset time.
For example, one or more temperature detection devices may be provided at a specific position of the inner pot of the electric cooker, the specific position may be a bottom or a side, and the temperature detection devices may be temperature sensors or the like. The temperature detection device can detect the temperature of a specific position of the electric cooker in real time.
In order to calculate the temperature increase value, an initial temperature value T1 of the specific location may be recorded when the heating time T1 is 0, that is, when heating is started. And recording the temperature value T2 of the specific position when the heating time T1 is T0, namely the heating time reaches the preset time. The temperature rise value is T2-T1.
And step S140, adjusting the heating mode of the heating device according to the temperature rise value.
It can be understood that during the heating period with the predetermined power and the predetermined power adjustment ratio, the temperature rise values of the electric cooking devices with shells of different materials are different, so that the material of the shell of the electric cooking device can be judged according to the temperature rise values to adaptively adjust the heating mode of the heating device, and further, the method provided by the embodiment of the invention is suitable for the electric cooking devices with shells of different materials.
Alternatively, in the embodiment of the present invention, the preset time t0 may range from 40S to 60S, the power regulation ratio of the predetermined heating mode may range from 10/16 to 13/16, and the power of the predetermined heating mode may range from 1000W to 1300W, but the embodiment of the present invention is not limited thereto, and the preset time, the first power regulation ratio, and the first power may be any values set reasonably.
Fig. 2 shows a flow chart of a heating control method for an electric cooker according to another embodiment of the present invention. As shown in fig. 2, according to the above embodiment, the adjusting the heating manner of the heating device according to the temperature rise value may include the following steps:
in step S202, whether the temperature rise value (T2-T1) is less than a preset temperature T0 is judged.
And step S204, controlling the heating device to operate in a first heating mode until the temperature rises to be boiling under the condition that the temperature rise value is less than the preset temperature.
And step S206, controlling the heating device to operate in a second heating mode until the temperature rises to boiling under the condition that the temperature rise value is not less than the preset temperature.
The temperature rise value is smaller than the preset temperature, which shows that the temperature rise is relatively slow. The temperature rise value is not less than the preset temperature, which shows that the temperature rises faster. The heating mode can be adjusted according to the speed of temperature rise. It is understood that the power adjusting ratio and power of the first heating mode may be different from the power adjusting ratio and power of the second heating mode.
For example, the electric cooker of the embodiment of the invention can be an IH electric cooker, the specific position is the bottom of an inner pot of the IH electric cooker, and the temperature detection device can be installed at the bottom of the inner pot of the IH electric cooker.
When the IH electric cooker starts to heat, firstly recording an initial temperature value T1 of the bottom of the inner pot, heating the IH electric cooker at a preset first power regulation ratio N1 and first power W1, recording a temperature value T2 of the bottom of the inner pot at the moment when the heating time reaches a preset time T0, and calculating a temperature rise value T2-T1 from the beginning of heating to the preset time T0.
In the case that the temperature rising value is less than the preset temperature T0, it is indicated that the temperature rising value of the inner pot bottom of the IH rice cooker is slower, that is, the bottom winding is relatively less, and it can be determined that the IH rice cooker using the plastic casing corresponds to the temperature rising value, in this case, the heating manner of the heating device needs to be adjusted to the heating manner (i.e., the first heating manner) corresponding to the IH rice cooker using the plastic casing until the food material (e.g., rice water) in the rice cooker is boiled.
Optionally, the power adjustment ratio N2 of the first heating mode may range from 13/16 to 16/16, and the power range W2 may range from 1200W to 1400W. It is understood that in the embodiment of the present invention, the power adjustment ratio of 13/16 means that the heating time of the heating module is 13S in each time period of 16S.
In the case that the temperature rise value is not less than the preset temperature T0, it is indicated that the temperature rise of the bottom of the inner pot of the IH rice cooker is faster, that is, the number of windings on the bottom is relatively large, and it can be determined that the IH rice cooker using the metal casing corresponds to the temperature rise value.
Optionally, the power adjustment ratio N3 of the second heating manner may range from 8/16W to 12/16, and the power W3 may range from 800W to 1200W, but the embodiment of the present invention is not limited thereto.
Alternatively, in the case where the specific location is the bottom of the inner pot of the electric cooker, the preset temperature T0 may range from 50 ℃ to 60 ℃, but the embodiment of the present invention is not limited thereto.
It is understood that the characteristic position in the embodiment of the present invention may be a side portion of the inner pot of the electric cooker. Taking the IH rice cooker as an example, the temperature detecting device may be installed at a side portion of an inner pot of the IH rice cooker, and when the temperature rising value is smaller than the preset temperature, it is indicated that the temperature rising of the side portion of the inner pot of the IH rice cooker is slow, that is, the winding of the side portion is relatively few, and it can be determined that the IH rice cooker using the metal casing corresponds to the temperature detecting device. In the case that the temperature rise value is not less than the preset temperature, it is indicated that the temperature rise of the side portion of the inner pot of the IH rice cooker is faster, that is, the number of windings of the side portion is relatively large, and it can be determined that the IH rice cooker using the plastic casing corresponds to the side portion.
