In this embodiment, an ion flame control method for a plasma cooking appliance is provided, which can be used for the above plasma cooking appliance, fig. 7 is a flowchart of the ion flame control method for the plasma cooking appliance according to the embodiment of the present invention, and as shown in fig. 7, the flowchart includes the following steps:
and S31, acquiring the magnetic field intensity of the electromagnetic coil.
The magnetic field intensity is the magnetic field intensity generated by an electromagnetic coil of the plasma cooker. The electromagnetic coil may be a solenoid coil, or may be another inductive coil capable of generating a magnetic field, which is not specifically limited in this application. The magnetic field inductor can be connected to solenoid department, when solenoid is in operating condition, can acquire magnetic field intensity through the magnetic field inductor, also can acquire magnetic field intensity through the magnetic inductor, can also acquire magnetic field intensity through other magnetic field detection device, and this application does not do not specifically limit to this.
And S32, adjusting the resistance value connected into the magnetic field control circuit, and determining the target magnetic field intensity of the electromagnetic coil.
The magnetic field intensity of the electromagnetic coil is influenced by the current, the current is different in magnitude, and the magnetic field intensity generated by the electromagnetic coil is different. If the resistance connected to the magnetic field control circuit is 1500 ohms, the output current of the magnetic field control circuit is the minimum at the moment, and the magnetic field intensity generated in the solenoid coil is the weakest; if the resistance connected to the magnetic field control circuit is 1000 ohms, the magnetic field intensity generated in the solenoid coil is increased to twice of the original intensity; if the resistance connected to the magnetic field control circuit is 500 ohms, the magnetic field intensity generated in the solenoid coil is strongest at this time.
And S33, controlling the ion flame of the plasma cooker based on the target magnetic field intensity.
The target magnetic field intensity represents the number of plasma entering the furnace cavity of the plasma cooker in unit time and is used for representing the intensity of ion flame required to be generated by the plasma cooker. The ion flame generated by the plasma cooker can be determined by the number of the plasma entering the furnace cavity of the plasma cooker in unit time. When the switching element is turned off, the ion flame is turned off without any resistance of the switching element.
According to the ion flame control method of the plasma cooker, provided by the embodiment of the invention, the magnetic field intensity of the electromagnetic coil is obtained, and the resistance adjusting module is controlled to adjust the magnetic field intensity of the electromagnetic coil, so that the control of the ion flame is realized. The method can accurately control the ion flame by flexibly adjusting the target magnetic field intensity of the electromagnetic coil, thereby realizing the accurate control of the heat production efficiency of the plasma cooker.
In this embodiment, an ion flame control method for a plasma cooking appliance is provided, which can be used for the above plasma cooking appliance, fig. 8 is a flowchart of the ion flame control method for the plasma cooking appliance according to the embodiment of the present invention, and as shown in fig. 8, the flowchart includes the following steps:
and S41, acquiring the magnetic field intensity of the electromagnetic coil. For details, refer to the related description of step S31 corresponding to the above embodiment, and are not repeated herein.
And S42, adjusting the resistance value connected into the magnetic field control circuit, and determining the target magnetic field intensity of the electromagnetic coil.
Specifically, the step S42 may include the following steps:
and S421, adjusting the switch element of the resistance adjusting module and determining the voltage dividing resistance connected with the switch element.
The switch element is connected with a plurality of divider resistors with different resistance values, and the divider resistors connected into the magnetic field control circuit can be determined by adjusting the switch element. Specifically, if the resistance values of the voltage dividing resistors are 500 ohms, 1000 ohms and 1500 ohms respectively, when the switching element is connected with the 1500 ohm voltage dividing resistor, the resistance equivalent to the access magnetic field control circuit is 1500 ohms; when the switching element is connected with a voltage dividing resistor of 1000 ohms, the resistor which is equivalent to be connected into the magnetic field control circuit is 1000 ohms; when the switching element is connected to a voltage dividing resistor of 500 ohms, the resistance equivalent to the access to the magnetic field control circuit is 500 ohms.
And S422, determining the current magnetic field intensity of the electromagnetic coil according to the voltage-dividing resistor connected with the switch element.
The switching elements are connected to different voltage dividing resistors corresponding to different magnetic field strengths. When the switch element is connected with the divider resistor with the maximum resistance value, the current led into the electromagnetic coil is minimum, and the current magnetic field intensity corresponding to the electromagnetic coil is minimum; when the switch element is connected with the divider resistor with the minimum resistance value, the current led into the electromagnetic coil is maximum, and the current magnetic field intensity corresponding to the electromagnetic coil is maximum.
And S423, judging whether the current magnetic field strength is consistent with the target magnetic field strength.
And comparing the current magnetic field strength with the target magnetic field strength, and determining the magnitude relation between the current magnetic field strength and the target magnetic field strength. If the current magnetic field strength is not consistent with the target magnetic field strength, step S424 is executed, otherwise, no resistance adjustment is performed.
And S424, adjusting the variable resistor to obtain the target magnetic field intensity corresponding to the electromagnetic coil.
If the current magnetic field strength is inconsistent with the target magnetic field strength, the resistance value in the current access magnetic field control circuit is not proper, and the resistance value in the access magnetic field control circuit is required to be finely adjusted to be corresponding to the target magnetic field.
And S43, controlling the ion flame of the plasma cooker based on the target magnetic field intensity. For a detailed description, refer to the related description of step S33 corresponding to the above embodiment, and the detailed description is omitted here.
According to the ion flame control method of the plasma cooker, provided by the embodiment of the invention, the current magnetic field strength of the plasma cooker is adjusted through the resistance adjusting module, and if the current magnetic field strength is inconsistent with the target magnetic field strength, the variable resistance is adjusted again to obtain the target magnetic field strength corresponding to the electromagnetic coil, so that the plasma cooker can accurately control the ion flame.
