All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a schematic flow chart of a constant temperature control method for an induction cooker according to an embodiment of the present invention. Fig. 2 is a schematic flow chart illustrating a process of determining a magnitude relationship between real-time heating power and minimum heating power in the constant temperature control method for an induction cooker according to an embodiment of the present invention. Fig. 3 is a schematic flow chart illustrating a real-time heating temperature of the constant temperature control method for the induction cooker according to an embodiment of the present invention is greater than a preset temperature.
As shown in fig. 1 to 3, the constant temperature control method for the induction cooker provided by the invention comprises the following steps:
s10: and judging the magnitude relation between the real-time heating temperature of the induction cooker during heating and the preset temperature of the induction cooker.
It should be noted that the real-time heating temperature may be a heating temperature value at any time in a heating state of the induction cooker, and the preset temperature of the induction cooker is a constant temperature point set by a user and required to be reached. The preset temperature can be changed according to the needs of the user.
S20: and if the real-time heating temperature is lower than the preset temperature, determining the change quantity of the power of the induction cooker along with the temperature change according to the maximum heating power of the induction cooker, the preset temperature of the induction cooker and the initial temperature of the induction cooker.
S30: and determining the real-time heating power of the induction cooker according to the change quantity of the power along with the temperature change, the maximum heating power, the real-time heating temperature and the initial temperature.
And heating according to the real-time heating power.
It should be noted that, when the real-time heating temperature is judged to be lower than the preset temperature, it indicates that the current heating temperature value does not reach the constant temperature point. At this time, the change amount of the power of the induction cooker along with the temperature change can be firstly determined according to the maximum heating power of the induction cooker, the preset temperature of the induction cooker and the initial temperature of the induction cooker. And secondly, determining the real-time heating power of the induction cooker according to the change quantity of the power along with the temperature change, the maximum heating power, the real-time heating temperature and the initial temperature. The maximum heating power of the induction cooker is a rated value of the induction cooker, and the initial temperature of the induction cooker is a temperature value of the induction cooker in an unheated state, wherein the temperature value can be a current room temperature value. The real-time heating power is substantially determined according to the real-time heating temperature, the preset temperature, the maximum heating power of the induction cooker and the initial temperature of the induction cooker, so that the real-time heating power is suitable for a specific environment with the initial temperature value, a specific heating state with the real-time heating temperature and the real-time heating power of the specific induction cooker with the rated maximum heating power, and the real-time heating power has strong pertinence and adaptability. Therefore, the real-time heating power can enable the real-time heating temperature of the induction cooker in the specific heating state in the specific environment to rise smoothly, and the problem that the error between the real-time heating temperature and the constant temperature point is large due to the fact that the temperature rising rate is too fast is avoided.
It should be noted that the variation of the power with temperature may be a step value of the power variation determined according to the maximum heating power and the preset temperature variation of the induction cooker, and the step value determines the increasing rate of the power and further determines the value of the temperature rising rate. Too fast a temperature rise may result in a large deviation between the real-time heating temperature and the preset temperature, while too slow a temperature rise may reduce the economy of the induction cooker. Therefore, the power determined according to the rated maximum heating power of the induction cooker and the preset temperature change of the induction cooker has the most practical and effective heating power and heating temperature step value along with the temperature change.
The real-time heating temperature is a variable, and the initial temperature is quantitative after the temperature value of the environment where the induction cooker is located is determined. The preset temperature and the initial temperature are both quantitative, so in conclusion, the variable value influencing the real-time heating power is the real-time heating temperature.
Compared with the prior art, the special constant temperature pot with the induction cooker is prepared from the material with the specific constant temperature point, the constant temperature control method of the induction cooker can adjust the constant temperature point in real time according to needs, the deviation between the real-time heating temperature and the constant temperature point is small, no special requirement is required on the material of the pot, and the cost is low.
Specifically, in this embodiment, determining the change amount of the power varying with the temperature according to the maximum heating power, the preset temperature of the induction cooker, and the initial temperature of the induction cooker specifically includes:
according to the formula
Determining the change of power with temperature, wherein Δ P represents the change of power with temperature, PmaxDenotes the maximum heating power, TsetIndicating a preset temperature, T0Indicates the initial temperature
Optionally, the determining the real-time heating power according to the variation of the power along with the temperature variation, the maximum heating power of the induction cooker, the real-time heating temperature, and the initial temperature may specifically include:
according to the formula
P＝Pmax-Δp(T-T0) (1)
And acquiring the real-time heating power of the induction cooker.
Wherein P represents the real-time heating power, PmaxRepresents the maximum heating power, T represents the real-time heating temperature, T0Representing the initial temperature, and Δ p represents the amount of change in power with temperature.
In this embodiment, after determining the real-time heating power of the induction cooker according to the change amount of the power varying with the temperature, the maximum heating power, the real-time heating temperature and the initial temperature, the method further comprises the following steps:
s40: and judging the magnitude relation between the real-time heating power and the minimum heating power of the induction cooker.
S41: and if the real-time heating power is smaller than the minimum heating power, taking the minimum heating power as the real-time heating power.
It should be noted that, for the purpose of ensuring that the temperature of the induction cooker continuously rises and finally reaches the preset temperature, when the real-time heating power is judged to be smaller than the minimum heating power, it is indicated that the real-time instant heating power is not enough to keep the real-time heating temperature of the induction cooker continuously rising at the moment, or the rising rate is low so that the real-time heating temperature does not meet the demand, and the minimum heating power is required to be used as the real-time heating power at the moment.
In the judging process, when the real-time heating power is greater than the minimum heating power, the technical scheme of heating according to the real-time heating power is executed.
In this embodiment, after determining the magnitude relationship between the real-time heating temperature of the induction cooker during heating and the preset temperature of the induction cooker, the method further includes the following steps:
s50: if the real-time heating temperature is higher than the preset temperature, determining the adjusted heating power of the induction cooker according to the real-time heating power and a preset power threshold;
and heating according to the adjusted heating power.
It should be noted that, in order to prevent the real-time heating rate of the induction cooker from being too high, when the real-time heating temperature is higher than the preset temperature, the adjusted heating power of the induction cooker needs to be determined according to the real-time heating power and the preset power threshold. The preset power threshold may be adjusted according to user needs, and may also affect the rate of real-time heating temperature change.
Further, after the adjusted heating power of the induction cooker is determined according to the real-time heating power and the preset power threshold, the method further comprises the following steps:
s51: judging the magnitude relation between the real-time heating temperature and the preset adjusting temperature of the induction cooker;
s511: and if the real-time heating temperature is higher than the preset adjusting temperature, determining the adjusted heating power as the difference between the real-time heating power and the preset power threshold.
It should be noted that, when the real-time heating temperature is judged to be greater than the preset adjusting temperature, it is indicated that the real-time heating power is too high, and if the heating is continued according to the real-time heating power, the rising rate of the real-time heating temperature is too high, so that the deviation between the real-time heating temperature and the preset temperature is finally large, which is not beneficial to the constant temperature process and is not beneficial to saving electric energy resources. At this time, in order to reduce the rising rate of the real-time heating power, the adjusted heating power is determined to be the difference between the real-time heating power and the preset power threshold.
Optionally, after determining the magnitude relationship between the real-time heating temperature and the preset adjustment temperature, the method further includes:
s512: and if the real-time heating temperature is lower than the preset adjusting temperature, determining that the adjusted heating power is the sum of the real-time heating power and a preset power threshold.
It should be noted that, when the real-time heating temperature is judged to be lower than the preset adjustment temperature, it indicates that the real-time heating power at this time has satisfied the standard that the real-time heating temperature reaches the preset temperature. However, in order to avoid the phenomenon of temperature reduction of the induction cooker at room temperature and ensure that the real-time heating temperature is always kept at the preset temperature, the adjusted real-time heating power is the sum of the real-time heating power and the preset power threshold.
In the above adjusting process, the preset power threshold may affect the rate of temperature change, and when the preset power threshold is smaller, the rate of the adjusted real-time heating power change is slower. Accordingly, when the preset power threshold is larger, the rate of change of the adjusted real-time heating power is faster. In actual use, the adjustment can be carried out according to the needs of users.
Optionally, the preset adjustment temperature is a sum of the preset temperature and a preset temperature threshold of the induction cooker.
It should be noted that the preset temperature threshold may affect the deviation between the real-time heating temperature and the preset temperature. That is, when the preset temperature threshold is small, the deviation between the real-time heating temperature and the preset temperature is small, and when the preset temperature threshold is large, the deviation between the real-time heating temperature and the preset temperature is also large. In actual use, the adjustment can be carried out according to the needs of users.
In the constant temperature control method for the induction cooker, provided by the embodiment of the invention, in order to realize that the constant temperature point of the induction cooker can be set according to needs, the real-time heating temperature of the induction cooker during heating is firstly obtained and compared with the preset temperature. The preset temperature is the constant temperature set by the user and can be adjusted according to the user requirement. And when the real-time heating temperature does not reach the preset temperature, determining the real-time heating power of the induction cooker according to the real-time heating temperature, the preset temperature, the maximum heating power of the induction cooker and the initial temperature of the induction cooker. The real-time heating temperature of the induction cooker can be increased smoothly by adjusting the real-time heating power, and the problem that the error between the real-time heating temperature and the constant temperature point is large due to the fact that the temperature rising rate is too high is avoided.

The preset temperature of the induction cooker is a constant temperature point which is set by a user and needs to be reached.
