Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The method and the device for controlling the fire quantity of the induction cooker provided by the embodiment of the invention can be applied to the induction cooker 100 shown in fig. 1. The induction cooker 100 comprises a microprocessor 110, a memory 120, an infrared sensor 130 and an ultrasonic generator 140, wherein the memory 120, the infrared sensor 130 and the ultrasonic generator 140 are all electrically connected with the microprocessor 110. The infrared sensor 130 and the ultrasonic generator 140 are mounted on the panel of the induction cooker 100.
In this embodiment, the detection of the water temperature can be realized by presetting the infrared sensor 130 to receive the thermal radiation signal of a specific wavelength range. Because the infrared signals emitted from different objects have different wavelengths, when the infrared sensor 130 is limited to receive only the infrared signals emitted from the liquid water, the obtained infrared radiation energy of the liquid water can be converted into an electrical signal and output to the microprocessor 110. The amount of energy radiated from the object is related to the temperature of the object, and the higher the temperature of the object is, the stronger the infrared radiation capability is, so that the microprocessor 110 can obtain the temperature information of the liquid water according to the electrical signal output by the infrared sensor 130.
In this embodiment, the ultrasonic generator 140 may emit an ultrasonic signal, or may receive a signal that is reflected by an object. After the ultrasonic generator 140 emits the ultrasonic signal, since the wavelengths of the ultrasonic signals returned by different objects are different, the ultrasonic generator 140 can detect the ultrasonic signal with a specific wavelength (i.e. the ultrasonic reflection signal returned by the liquid water), so as to detect the liquid level height of the water in the pot. For example, after the ultrasonic generator 140 emits the ultrasonic signal, the microprocessor 110 may calculate the time from the emission of the ultrasonic signal to the first return of the liquid water to the ultrasonic reflection signal and the time from the last return of the liquid water to the ultrasonic reflection signal, then calculate the real-time liquid level data of the liquid water according to the propagation velocity of the ultrasonic signal in the air, and automatically adjust the fire volume according to the real-time liquid level data.
In this embodiment, the outer surface of the faceplate of the induction cooker 100 is provided with a region for placing a pot, the ultrasonic generator 140 may be disposed in the faceplate at a position corresponding to the pot placing region, preferably, the ultrasonic generator 140 is opposite to the center position of the bottom of the pot placed on the faceplate, so as to detect the liquid level data in the pot by the ultrasonic generator 140.
Fig. 2 is a schematic flow chart of a method for controlling a fire quantity of an induction cooker according to an embodiment of the present invention. It should be noted that the method for controlling the fire amount of the induction cooker according to the present invention is not limited to the specific procedure shown in fig. 2 and described below. It should be understood that in other embodiments, the order of some steps in the method for controlling the fire of the induction cooker according to the present invention may be interchanged according to actual needs, or some steps may be omitted or deleted. The method for controlling the fire amount of the induction cooker can be applied to the microprocessor 110, and the specific process shown in fig. 2 will be described in detail below.
Step S101, after the induction cooker is started to have the automatic control mode of the fire quantity, detecting real-time liquid level data of liquid water in the pot.
Wherein, the pot is placed on the panel of the induction cooker 100. In practical application, a button for controlling the on/off of the fire automatic control mode can be arranged on the induction cooker 100, a user controls the induction cooker 100 to turn on/off the fire automatic control mode by operating the button, and after the induction cooker 100 turns on the fire automatic control mode, liquid level data of liquid water in a cooker is detected.
Optionally, the ultrasonic generator 140 is configured to emit an ultrasonic signal after being turned on, and output a feedback signal when receiving an ultrasonic reflection signal that the ultrasonic signal is reflected by the liquid water, the microprocessor 110 may turn on the ultrasonic generator 140 after the induction cooker 100 is turned on in the fire amount automatic control mode, so that the ultrasonic generator 140 emits the ultrasonic signal, the ultrasonic generator 140 outputs the feedback signal to the microprocessor 110 every time the ultrasonic reflection signal with a specific wavelength (that is, the ultrasonic reflection signal of the liquid water) is received after emitting the ultrasonic signal, and the microprocessor 110 may detect the real-time liquid level data of the liquid water according to the feedback signal output by the ultrasonic generator 140.
Specifically, as shown in fig. 3, the step of detecting the real-time liquid level data of the liquid water according to the feedback signal output by the ultrasonic generator 140 includes:
sub-step S1011, calculating a first time difference that elapses from when the ultrasonic wave generator 140 emits the ultrasonic wave signal to when the ultrasonic wave generator 140 outputs the feedback signal for the first time.
Sub-step S1012, calculating a second time difference that elapses from when the ultrasonic wave generator 140 transmits the ultrasonic wave signal to when the ultrasonic wave generator 140 outputs the feedback signal for the last time.
In this embodiment, the ultrasonic generator 140 may transmit the ultrasonic signal according to a preset period (e.g., 3s) after being turned on, that is, the ultrasonic generator 140 transmits the ultrasonic signal again after a preset period every time the ultrasonic signal is transmitted. Therefore, the first time difference may be understood as a time difference that the ultrasonic generator 140 experiences when the liquid water returns to the ultrasonic reflection signal for the first time from the time after each transmission of the ultrasonic signal to the time before the ultrasonic signal is transmitted again, which corresponds to a distance between the liquid water at the lowest level and the ultrasonic generator 140, and the second time difference may be understood as a time difference that the ultrasonic generator 140 experiences when the liquid water ultrasonic reflection signal is received for the last time from the time after each transmission of the ultrasonic signal to the time before the ultrasonic signal is transmitted again, which corresponds to a distance between the liquid water at the highest level and the ultrasonic generator 140.
And a substep S1013 of calculating the real-time liquid level data according to the first time difference and the second time difference.
Wherein, the substep S1013 specifically includes: and calculating a first distance according to the first time difference and a preset propagation speed, calculating a second distance according to the second time difference and the preset propagation speed, and calculating a difference value between the first distance and the second distance to obtain the real-time liquid level data.
In the present embodiment, the preset propagation speed is a propagation speed of the ultrasonic signal in the air. Assuming that the first time difference calculated by the microprocessor 110 is T1, the second time difference is T2, and the predetermined propagation speed is C, the first distance x 1-C × T1, the second distance x 2-C × T2, and x2-x1 are real-time liquid level data according to the ultrasonic ranging formula L-C × T.
And S102, controlling the fire quantity of the induction cooker according to the real-time liquid level data.
In this embodiment, in order to improve the accuracy of controlling the fire amount of the induction cooker 100, the liquid level change rate of the liquid water may be calculated first, and then the fire amount may be adjusted according to the liquid level change rate. As shown in fig. 4, the step S102 includes the following sub-steps:
and a substep S1021, calculating a liquid level change rate according to the real-time liquid level data.
Specifically, the sub-step S1021 includes: calculating the liquid level change rate according to the formula of (H1-H)/H1 100%, wherein μ is the liquid level change rate, H is the real-time liquid level data, and H1 is an initial value in the real-time liquid level data. It is understood that H1 is the first calculated liquid level data after the ultrasonic generator 140 is turned on, and H is the real-time detected liquid level data (including the first calculated liquid level data H1).
And a substep S1022, adjusting the fire quantity of the induction cooker according to the liquid level change rate.
Specifically, the sub-step S1022 includes: calculating the fire amount percentage of the induction cooker 100 according to a formula A of-1.25 mu + 100%, and adjusting the fire amount of the induction cooker 100 according to the fire amount percentage, wherein mu is the liquid level change rate, and A is the fire amount percentage. As shown in fig. 5, which is a schematic diagram of the corresponding relationship between the percentage of fire a and the rate of change of liquid level μ, when the liquid level in the pot is only 20%, that is, the rate of change of liquid level μ is 80%, the percentage of fire a calculated at this time is 0, the fire switch of the induction cooker 100 can be directly controlled to be turned off, so as to prevent the water from being dried due to the remaining temperature in the pot and prevent the pot from being dried.
Optionally, the infrared sensor 130 is configured to output a detection signal according to infrared radiation energy of the liquid water, and after the fire control mode of the induction cooker 100 is started, the infrared sensor 130 may be used to detect the temperature of the liquid water in the pot to determine whether the water temperature reaches the boiling point. As shown in fig. 6, the method includes:
and step S201, after the fire control mode of the induction cooker is started, calculating the temperature of the liquid water according to the detection signal output by the infrared sensor.
In this embodiment, after the induction cooker 100 starts the automatic fire control mode, the infrared sensor 130 outputs a detection signal to the microprocessor 110 in real time, wherein the detection signal is an electrical signal obtained by converting the infrared sensor 130 according to the infrared radiation energy of the liquid water; the microprocessor 110 may preset a corresponding relationship between the voltage of the detection signal and the temperature of the liquid water, and when receiving the detection signal output by the infrared sensor 130, the microprocessor may determine the temperature information corresponding to the detection signal according to the corresponding relationship.
Step S202, when the temperature of the liquid water reaches a preset boiling temperature, detecting real-time liquid level data of the liquid water.
In this embodiment, after calculating the temperature of the liquid water, the microprocessor 110 compares the temperature of the liquid water with a preset boiling temperature to determine whether the liquid water in the pot starts to boil, and after determining that the water boils, sends an on signal to the ultrasonic generator 140 to turn on the ultrasonic generator 140. For example, when the preset boiling temperature is 97 ℃, and when the temperature of the liquid water is detected to be greater than or equal to 97 ℃, it is determined that the water starts to boil, and then a start signal is sent to start the ultrasonic generator 140, so that the ultrasonic generator 140 starts to emit an ultrasonic signal.
After the ultrasonic generator 140 is turned on, real-time liquid level data of the liquid water is detected according to the feedback signal output by the ultrasonic generator 140, which may specifically refer to the corresponding content of the foregoing step S101.
And S203, controlling the fire quantity of the induction cooker according to the real-time liquid level data.
In this embodiment, the step S203 can refer to the corresponding content of the aforementioned step S102.
It can be seen that, in this embodiment, after the induction cooker 100 is turned on to the fire amount automatic control mode, the infrared sensor 130 is used to detect the water temperature in the pot, when the water temperature in the pot reaches the preset boiling temperature, the ultrasonic generator 140 is controlled to be turned on, and the liquid level data of the liquid water is detected in real time according to the feedback signal output by the ultrasonic generator 140, so that the fire amount is automatically adjusted according to the real-time change of the liquid level data of the liquid water in the pot, and the user experience is provided.
