Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The heating control method, apparatus, and device of the embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a heating control method according to an embodiment of the present application.
As shown in fig. 1, the heating control method includes:
Specifically, the heating control method provided by this embodiment may be configured in any electric heating device, where the method is used to adjust the power adjustment ratio of the electric heating device according to the voltage value currently loaded on the electric heating device, so as to ensure that the heating powers of the electric heating device are the same when the electric heating device operates at different voltages.
The electric heating device in the embodiments of the present application may be any product that can be heated, heat preserved, baked or baked by using electric energy, for example, it may be an electric cooker, an electric steamer, a pressure cooker, an electric heater, etc.
Specifically, in the embodiment of the present application, the current working voltage value of the electric heating device may be determined in a plurality of ways, for example, a voltage sensor is arranged at a power end of the electric heating device, or a voltage acquisition circuit is arranged at the power end of the electric heating device, so as to monitor the voltage value of the electric heating device during use; alternatively, a voltage sensor or a sampling circuit is provided at both ends of the heating resistor, and the voltage value at both ends of the heating resistor is directly monitored.
And 102, determining the current power regulation ratio of the electric heating equipment according to the current working voltage value.
And 103, adjusting the heating mode of the electric heating equipment according to the current power regulation ratio.
In the embodiment of the application, in order to stabilize the output power of the electric heating device when the voltage changes, the heating resistor in the electric heating device can be controlled to periodically work in the processes of heating, stopping, heating and stopping. The power regulation ratio refers to the ratio of the duration of the heating phase to the total duration of the cycle in the cycle consisting of the heating phase and the stopping phase.
For example, if the duty ratio is 10/32, the heating time of the heating resistor is 10s and the stop time is 22s in the duty cycle of 32 seconds.
Specifically, the power P of the electric heating device refers to the heat generated by the electric heating device in a unit time, and if it is to be ensured that the power P is kept constant when the voltage of the heating device changes, it is to be ensured that the heat generated within a certain time period is constant when the voltage changes, and the relationship between the heat W generated by the electric heating device within a certain time period t, the voltage U loaded at two ends of the heating resistor, and the resistance value of the heating resistor is R is as follows:
W＝t×U2/R
from the above formula, when the voltage U is changed, the heating time can be adjusted to ensure that the heat generated by the electric heating device is not changed. Therefore, in this embodiment of the present application, the step 102 specifically includes:
and determining the heating time of the electric heating equipment in one period according to the current working voltage value.
Specifically, a heating stage and a stopping stage are included in one period, so that the heat generated by the heating resistor in one period can be ensured to be stable by controlling the heating time in one period according to the current working voltage value.
Accordingly, the step 103 includes:
and adjusting the time for the heating resistor in the electric heating equipment to be connected into the heating loop in one period according to the heating time.
During concrete implementation, the electric heating resistor can be connected in the heating circuit after being connected in series with the switch tube, thereby, after the heating time is determined, the periodic conduction of the switch tube for a certain time can be controlled, so that the heating resistor is connected into the heating circuit in each period to generate certain heat, when the current working voltage value of the electric heating equipment changes, the conduction time of the switch tube is adjusted, namely the duty ratio of the switch tube, and the heat generated by the heating resistor in each period can be ensured to be the same. Thereby ensuring the performance consistency and stability of the electric heating equipment.
According to the heating control method provided by the embodiment of the application, the current working voltage value of the electric heating equipment is determined firstly, then the current power regulation ratio of the electric heating equipment is determined according to the current working voltage value, and further the heating mode of the electric heating equipment is regulated according to the power regulation ratio. Therefore, when the working voltage of the electric heating equipment is changed, the output heat is unchanged, the consistency and the stability of the electric heating equipment are improved, and the user experience is improved.
Through the analysis, the heating time of the electric heating equipment in one period can be adjusted according to the current working voltage value of the electric heating equipment, so that the output power of the electric heating equipment is ensured to be unchanged under different working voltages. In one possible implementation, the electric heating device usually has a plurality of power levels to meet the needs of the user, and therefore, the heating time of the electric heating device in one cycle is also determined in combination with the current operating level. The heating control method provided by the present application is further described below with reference to fig. 2 by taking the above case as an example.
Fig. 2 is a schematic flow chart of a heating control method according to another embodiment of the present application.
As shown in fig. 2, the heating control method includes:
In particular, the current power level of the electric heating device may be determined in a number of ways.
Example 1
And determining the current power level of the electric heating equipment according to the current working state of the electric heating equipment.
For example, if the electric heating device is currently operated in the "rice cooking" state, the corresponding power level may be P1, and if the electric heating device is currently operated in the "warm keeping" state, the corresponding power level may be P2.
Example two
And determining the current power level of the electric heating equipment according to the position of the position switch in the electric heating equipment.
For example, the power level associated with the position switch in the "1" position is P3, the power level associated with the position switch in the "2" position is P4, and so on. The embodiments of the present application do not limit this.
Further, the resistance value of the heating resistor may be determined in various ways.
Example 1
And acquiring the resistance value of the heating resistor in the attribute parameters of the electric heating equipment.
Specifically, after the electric heating device is designed, the resistance value of the heating resistor is fixed. Therefore, the resistance value of the heating resistor of the electric heating equipment can be stored locally in advance in the form of the attribute parameters, so that the resistance value of the heating resistor in the attribute parameters can be directly obtained when the heating time of the heating resistor is determined.
Example two
And determining the resistance value of the heating resistor corresponding to the current power grade according to the mapping relation between the preset power grade and the heating resistor.
In one possible implementation form, the electric heating device is configured with different heating resistors for different power levels, for example, in an electric heater, different powers correspond to different numbers of resistance wires. Therefore, in the electric heating device, the mapping relationship between the power level and the heating resistor can be preset in advance, so that after the current power level is determined, the current resistance value of the heating resistor can be determined by inquiring the preset mapping relationship.
And 204, determining the heating time of the heating resistor in one period according to the resistance value, the target heat value and the voltage value of the heating resistor.
And step 205, adjusting the time for the heating resistor in the electric heating equipment to access the heating loop in one period according to the heating time.
According to the heating control method provided by the embodiment of the application, the current working voltage value of the electric heating equipment is determined, then the current power level of the electric heating equipment and the resistance value of the heating resistor are determined, the target energy value of the heating resistor in one period is determined according to the current power level, the heating time of the heating resistor in one period is determined according to the target energy value, the resistance value of the heating resistor and the working voltage value, and the time for the heating resistor to be connected into a heating loop in one period is adjusted according to the heating time. Therefore, under any power level, when the working voltage of the electric heating equipment is changed, the output heat is unchanged, the consistency and the stability of the electric heating equipment are improved, and the user experience is improved.
The heating control method provided by the present application is further described below by taking an electric heating device as an example of a pressure cooker.
At present, in the use process of the electric pressure cooker, after a user sets pressure maintaining time t1, the electric pressure cooker starts to be electrified and heated in voltage, when the working voltage is reached, the electric pressure cooker is switched to a heat preservation state until cooking is finished, in the cooking process, a heating plate in the electric pressure cooker is electrified and operated discontinuously at a fixed power regulation ratio, when the electric pressure cooker is electrified, the heating plate converts electric energy into heat energy, and when the electric pressure cooker is powered off, the electric pressure cooker preserves heat.
However, when the electric pressure cookers of the same type are used in different areas, if the working voltages of the electric pressure cookers are different, the electric pressure cookers of the same type will produce different foods within the same pressure maintaining time. If the heating control method provided by the application is adopted, the power adjusting ratio of the heating plate in the electric pressure cooker is adjusted according to the working voltage of the electric pressure cooker, so that the heating plate in the electric pressure cooker with the same model can be ensured, and the heat emitted is constant in the process of powering on and powering off when the electric pressure cooker works under different working voltages.
For example, if the electric pressure cooker is set to use power adjustment ratio of 24/32 at 220V operating voltage, the heat quantity W generated by the heating plate in a heating and stopping period is:
If the electric pressure cooker is in operation and the current working voltage is detected to be 240V, the heat quantity W generated by the heating plate is kept constant in order to keep a heating and stopping period, namely according to the fact that the electric pressure cooker is in operation
The current power modulation ratio x/32 is determined, and the current power modulation ratio is 22/32 through calculation.
When 32s is a cycle of heating and stopping, and the operating voltage is 220V, the heating time is 24 seconds, the stopping time is 8 seconds, and when the operating voltage is 240V, the heating time is 22 seconds, and the stopping time is 10 seconds within 32 s. Therefore, the heat generated by the heating plate is not changed no matter how the working voltage is changed in the heating and stopping period of 32 s.
