Background
The application of induction cookers brings great convenience to our daily life, and with the continuous development of global trade, induction cookers in the same region can be sold to different regions of the world. Because the voltages of different countries are different, when the induction cooker is applied to different regional environments, the induction cooker needs to adapt to various complex power grid environments and meet the requirement of a wide range of voltage sections (such as 120V-280V).
Under the condition of high voltage (such as 200V-270V), the power requirement of 2000W is met, the current can be controlled within the current range of 10A, and an Insulated Gate Bipolar Transistor (IGBT) in the induction cooker can be controlled to keep a short opening width, so that the resonant frequency of the induction cooker reaches more than 20KHz, and great electromagnetic noise is not generated. However, under the condition of low voltage (such as 120V-180V), the following abnormity occurs in the induction cooker to meet the power requirement of 2000W as well: the current reaches more than 10A and exceeds the bearing range of the power line; the Insulated Gate Bipolar Transistor (IGBT) keeps a longer opening width, so that the resonant frequency of a main circuit of the induction cooker is low and the electromagnetic noise is high, and the peak current in the Insulated Gate Bipolar Transistor (IGBT) is increased and the synchronous state is delayed, so that the loss of the Insulated Gate Bipolar Transistor (IGBT) is caused.
Most of the existing induction cookers are designed for specific voltage, are only suitable for specific areas, cannot be universal in countries with different voltages, and when the induction cookers in a certain high-voltage area are applied to a low-voltage area, additional accessories (such as a transformer) are required to be added to realize normal use of the induction cookers.

Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The main solution of the embodiment of the invention is as follows: detecting the current input voltage value of the induction cooker; and judging whether the input voltage value is smaller than a preset voltage value, judging a preset voltage interval where the input voltage value is located when the input voltage value is smaller than the preset voltage value, and adjusting the current actual power of the induction cooker according to the preset voltage interval where the input voltage value is located.
As the induction cooker normally used in the high-pressure state in the prior art is used in the low-pressure state, additional accessories are required to be added for realization.
The invention provides a solution, which is characterized in that the current input voltage value of an induction cooker is detected; whether the input voltage value is smaller than the preset voltage value or not is judged, when the input voltage value is smaller than the preset voltage value, the preset voltage interval where the input voltage value is located is judged, and the current actual power of the induction cooker is adjusted according to the preset voltage interval where the input voltage value is located.
The operation terminal of the electromagnetic oven power control method of the invention can be a PC, a terminal device such as a smart phone and the like, and can also be an electromagnetic oven, and the operation terminal is taken as the electromagnetic oven for example to illustrate.
As shown in fig. 1, in the embodiment of the present invention, the method for controlling power of an induction cooker includes the following steps:
s100, detecting the current input voltage value of the induction cooker;
when the induction cooker is used, firstly, the voltage value input by the induction cooker is detected, wherein the input voltage value is the voltage value of a power grid of a region where the induction cooker is connected. The detection of the input voltage value may be realized by a detection device such as a voltage detection circuit inside the induction cooker, or may be realized by a voltage detection device (such as a voltmeter and a universal meter) outside the induction cooker, which is not limited specifically herein.
S200, judging whether the input voltage value is smaller than a preset voltage value or not;
and comparing the detected input voltage value of the induction cooker with the preset voltage value. The preset voltage value can be set according to the minimum voltage value of the induction cooker when the induction cooker is normally used in the area of the high-voltage power grid without abnormality, and can also be set according to the actual use requirements of users or the experience of designers. Specifically, the preset voltage value may be set to 200V, that is, the voltage value may be considered to be in a high-voltage use environment when being higher than 200V, and the voltage value may be considered to be in a low-voltage use environment when being lower than 200V.
S300, when the input voltage value is smaller than the preset voltage value, judging a preset voltage interval in which the input voltage value is positioned;
when the input voltage value is smaller than the preset voltage value, the induction cooker is in a low-voltage use environment, and the preset voltage interval where the input voltage value is located is judged. The preset voltage interval is a voltage value which is less than 200V and is divided into a plurality of voltage intervals, the intervals of endpoints of each preset voltage interval can be the same or different, and the number of the preset voltage intervals can be determined according to specific conditions. Each preset voltage interval corresponds to a power adjustment strategy, and the power adjustment strategies can comprise power limitation strategies, current limitation strategies and other adjustment strategies capable of effectively adjusting the power of the induction cooker. The preset voltage interval may be an open interval or a closed interval. When the preset voltage interval is set as an open interval, when the input voltage value falls into a first preset voltage interval, the input voltage value corresponds to a first power adjustment strategy corresponding to the first preset voltage interval; when the input voltage value falls into the endpoint value of the preset voltage interval, the power adjustment strategy corresponding to the input voltage value may be any one of the power adjustment strategies corresponding to two preset voltage intervals adjacent to the endpoint value in front and back, and may also be preset according to actual conditions.
In addition, when the input voltage value is greater than the preset voltage value, the induction cooker can be considered to be in a normal use state, and the actual power of the induction cooker does not need to be adjusted.
S400, adjusting the current actual power of the induction cooker according to the preset voltage interval where the input voltage value is located.
After the power adjustment strategy corresponding to the detected input voltage value is determined, the current actual power of the induction cooker can be adjusted according to the power adjustment strategy. If the detected input voltage value corresponds to a power limiting strategy, limiting the actual power of the induction cooker according to the power limiting strategy, so that the actual power of the induction cooker does not exceed a reasonable range; if the detected input voltage value corresponds to a current limiting strategy, limiting the actual current of the induction cooker according to the current limiting strategy, so that the actual current of the induction cooker does not exceed a reasonable range, and under the condition that the voltage value is not changed, the actual power of the induction cooker does not exceed the reasonable range. Specifically, in order to adapt to different use requirements, the actual power or current of the induction cooker can be detected in real time by adjusting the power of the induction cooker, and the power of the induction cooker is adjusted when the actual power or current of the induction cooker exceeds a reasonable range.
Specifically, as shown in fig. 2, in the present embodiment, the step S400 includes:
s410, determining a power limit value corresponding to the input voltage value according to a preset voltage interval in which the input voltage value is located and a first preset corresponding relation;
and S420, adjusting the current actual power of the induction cooker according to the power limit value.
When the power adjustment strategy is used for controlling the induction cooker, a first preset corresponding relation between preset voltage intervals and power limit values can be established in advance, namely, each preset voltage interval corresponds to one power limit value, and the first preset corresponding relation can be determined through methods such as experience accumulation, experimental tests or simulation calculation. The power limit value can be the maximum output power value which can not cause the abnormality of the induction cooker when any voltage value in the preset voltage interval is taken as an input voltage value; in consideration of safety or other practical use conditions, the power limit value can also be a voltage value smaller than the maximum output power value, so that the abnormality of the induction cooker can not be caused while the use requirement of a user is ensured.
And after the preset voltage interval where the detected input voltage value is located is determined, determining a power limit value of the induction cooker when the induction cooker operates in the environment of the input voltage value according to the first preset corresponding relation. And after the power limit value of the induction cooker under the input voltage value is determined, limiting the actual power of the current operation of the induction cooker not to exceed the power limit value.
Specifically, as shown in fig. 3, in the present embodiment, in the case that the power limitation is performed only when the currently operating actual power exceeds the power limit value, the step S420 includes:
s421, acquiring the current actual power value of the induction cooker;
s422, judging whether the actual power value is larger than the power limit value;
and S423, when the actual power value is larger than the power limit value, the electromagnetic oven operates according to the power limit value.
And S424, when the actual power value is smaller than or equal to the power limit value, the electromagnetic oven operates according to the actual power value.
The current actual power value of the induction cooker can be obtained by directly detecting the actual power of the induction cooker; the current actual power value of the induction cooker can also be obtained by detecting the actual current value of the induction cooker and combining the detected input voltage value through calculation. And comparing the obtained actual power value of the induction cooker with the power limit value, and judging whether the actual power value is greater than the power limit value. When the actual power value of the electromagnetic oven is larger than the power limit value, the electromagnetic oven is in an abnormal state, and at the moment, the operation power of the electromagnetic oven needs to be controlled to be reduced to the power limit value, so that the electromagnetic oven operates according to the power limit value, and the normal operation of the electromagnetic oven is ensured. When the actual power value is less than or equal to the power limit value, the electromagnetic oven is in a normal operation state, the power of the electromagnetic oven does not need to be adjusted at the moment, and the electromagnetic oven can operate according to the current actual power value.
The power of the induction cooker is adjusted according to the current input voltage value of the induction cooker through the steps, the induction cooker can not exceed reasonable power when being positioned in different voltage sections, the induction cooker is prevented from being abnormal due to overlarge current, however, the induction cooker has the difference of external components, the actual power value under the control of the current power limit value can have certain deviation due to the fact that the sampling circuit is enlarged partially, the amplification circuit is deviated in multiple, and the like, and therefore the induction cooker is abnormal due to the overlarge current. In the electromagnetic oven, the control of the opening width of the IGBT switch can realize the control of the power and the current of the electromagnetic oven, and the control of the opening width of the IGBT switch can be realized by the control of the driving pulse of the driving control circuit. Therefore, on the basis of the power control step of the induction cooker, the power of the induction cooker can be controlled in an auxiliary mode through the driving pulse, and the induction cooker can be further guaranteed to be normally used in a low-voltage state without abnormity.
Therefore, as shown in fig. 4, in this embodiment, after the step S400, the method further includes:
s500, determining a driving pulse limit value corresponding to the input voltage value according to a preset voltage interval in which the input voltage value is located and a second preset corresponding relation;
s600, adjusting the current actual power of the induction cooker according to the limit value of the driving pulse.
When the driving pulse is used for controlling the power of the induction cooker, a second preset corresponding relation between the preset voltage intervals and the driving pulse limit values can be established in advance, namely, each preset voltage interval corresponds to one driving pulse limit value, and the second preset corresponding relation can be determined through methods such as experience accumulation, experimental tests or simulation calculation. The drive pulse limit value can be any drive pulse value which can not cause the abnormity of the induction cooker when any voltage value in the preset voltage interval is taken as an input voltage value.
And determining a driving pulse limit value when the induction cooker operates under the environment of the input voltage value according to the preset voltage interval in which the input voltage value is located and the second preset corresponding relation. After the limit value of the driving pulse of the induction cooker under the input voltage value is determined, the current driving pulse value of the induction cooker is limited not to exceed the limit value of the driving pulse, so that the control of the power and the current of the induction cooker is realized.
Specifically, as shown in fig. 5, in this embodiment, the step S600 includes:
s610, acquiring a current driving pulse value of the induction cooker;
s620, judging whether the driving pulse value is larger than the driving pulse limit value;
s631, when the driving pulse value is larger than the driving pulse limit value, the electromagnetic oven operates according to the driving pulse limit value.
To realize the limitation on the driving pulse of the induction cooker, the current driving pulse value of the induction cooker can be obtained firstly, for example, the current driving pulse value can be directly read from a singlechip in the induction cooker; judging whether the current driving pulse value is larger than the driving pulse limit value or not, and when the driving pulse value is larger than the driving pulse limit value, namely the electromagnetic oven is under the driving control operation of the current driving pulse value, the actual power in the electromagnetic oven possibly exceeds a reasonable value to cause the electromagnetic oven to be abnormal, so that the current driving pulse value is required to be reduced to the driving pulse limit value at the moment, and the electromagnetic oven is under the driving control of the driving pulse limit value to realize the normal use of the electromagnetic oven.
Further, step S600 further includes: and S632, when the current driving pulse value is less than or equal to the driving pulse limit value, operating the induction cooker according to the current driving pulse value. The actual power of the induction cooker can be considered to be in a reasonable range, the induction cooker works normally, and the auxiliary adjustment of the actual power of the induction cooker through driving pulses is not needed.
In the electromagnetic oven, because of the existence of various deviations, after the current actual power of the electromagnetic oven is adjusted according to the power limit value, the current actual current value in the electromagnetic oven may still be too large to cause the abnormality of the electromagnetic oven, so that the current actual current value can be used as a trigger condition for adjusting the actual power of the electromagnetic oven by using the driving pulse, and it is further ensured that the electromagnetic oven can be normally used in a low-voltage state without abnormality, therefore, as shown in fig. 6, in this embodiment, the step of S600 further includes:
s700, determining a current limit value corresponding to the input voltage value according to a preset voltage interval in which the input voltage value is located and a third preset corresponding relation, and detecting the current actual current value of the induction cooker;
s800, judging whether the current actual current value is larger than a current limit value;
s910, when the current actual current value is larger than the current limit value, the step S600 is executed.
The third preset corresponding relation between the preset voltage intervals and the current limit values is established in advance, namely, each preset voltage interval corresponds to one current limit value, and the third preset corresponding relation can be determined through methods such as experience accumulation, experimental tests or simulation calculation and the like. The current limit value can be a current threshold value which can ensure that the induction cooker is not abnormal when any voltage value in the preset voltage interval is taken as an input voltage value.
And determining a current limit value of the induction cooker when the induction cooker operates in the environment of the input voltage value according to the preset voltage interval in which the input voltage value is located and the third preset corresponding relation. And meanwhile, the current actual current value of the induction cooker is detected, and the current actual current of the induction cooker can be realized through a current detection module in the induction cooker and can also be obtained through external current detection equipment. Comparing the current actual current value with the current limit value of the induction cooker, judging whether the current actual current value is greater than the current limit value, if the current actual current value is greater than the current limit value, the induction cooker is considered to be in an abnormal state, executing the step S600, and adjusting the actual power of the induction cooker through the driving pulse.
Further, step S600 further includes: s920, when the current actual current value is smaller than or equal to the current limit value, the induction cooker operates according to the current actual power. When the current actual current value is less than or equal to the current limit value, the induction cooker can be considered to be in a normal state at the moment, so the current actual power of the induction cooker does not need to be adjusted through driving pulses,
it should be noted that, when the current actual current value is used as the trigger condition for adjusting the actual power of the induction cooker by using the driving pulse, step S500 and steps S700, S800, and S900 may be executed synchronously or asynchronously, and only before the current actual power of the induction cooker is adjusted according to the driving pulse limit value, the driving pulse limit value and the current limit value are determined according to the input voltage value, and when the current actual current value exceeds the current limit value, the driving pulse may be touched to adjust the actual power of the induction cooker.
Based on the above-mentioned power control method for the induction cooker of the present embodiment, a specific embodiment of the present embodiment is provided below. Before the power control method of the induction cooker of this embodiment is executed, each preset value is set, the preset voltage value is set to 200V, the preset voltage interval includes (180V, 200V), (160V, 180V), (130V, 160V), (0V, 130V), and the first preset relationship is: the first power limit value corresponding to the preset voltage interval (180V, 200V) is 1700W, the second power limit value corresponding to the preset voltage interval (160V, 180V) is 1500W, the third power limit value corresponding to the preset voltage interval (130V, 160V) is 1100W, and the fourth power limit value corresponding to the preset voltage interval (0V, 130V) is 800W. Firstly, detecting the current input voltage value of the induction cooker, and if the current input voltage value is detected to be 220V, maintaining the current power operation of the induction cooker without regulation; if the current input voltage value is detected to be 190V, the 190V is located in a preset voltage interval (180V, 200V), the power limit value of the induction cooker under the 190V input voltage can be determined to be 1700W according to the first preset relation and the preset voltage interval, the current actual power value of the induction cooker is obtained, the size relation between the current actual power value and 1700W is judged, if the current actual power value is detected to be 1650W (smaller than the power limit value 1700W), the current actual power value of the induction cooker does not need to be adjusted, and if the current actual power value is detected to be 1700W (equal to the power limit value 1700W), the current actual power value of the induction cooker does not need to be adjusted, if the current actual power value is 1750W (larger than the power limit value 1700W), reducing the current actual power value of the induction cooker, and enabling the induction cooker to operate according to the power limit value 1700W or the power lower than the power limit value 1700W; if the current input voltage value is 200V, 200V is not larger than the preset voltage value 200V, or is not located in any one of the preset voltage intervals, the electromagnetic oven can maintain the current power operation without adjustment, can operate according to the power limit value corresponding to the interval (180V, 200V) of 1700W or adjust according to the power limit value, and can operate according to other values (such as 2000W) set according to actual conditions.
In the scheme disclosed by the embodiment, when the induction cooker is used in a low-voltage environment, the current actual power of the induction cooker is adjusted differently according to the difference of the voltage intervals where the input voltage values of the induction cooker are located, so that the induction cooker which is normally used in a high-voltage state through an intelligent and simple method can also be normally used in the low-voltage environment, and the abnormal use of the induction cooker in the low-voltage environment is avoided.
