Referring to fig. 1 to 3, based on the above-mentioned cooking appliance, the method for controlling the cooking appliance specifically includes the following steps:
s10: acquiring a sound wave signal generated by the sound generating device 3 in the working process of the cooking appliance;
it will be appreciated that the sound generating means 3 is driven by the steam to generate a sound wave signal which is detected by the detecting means and then fed to the control means for corresponding analysis and generation of control instructions.
S20: and controlling the cooking appliance to work according to the sound wave signal.
According to the technical scheme, the cooking utensil is provided with the sound generating device 3 which can be driven by steam to generate specific sound waves, after the detection device acquires the detected sound wave signals, the cooking utensil is controlled to work according to the sound wave signals, the detection of the cooking state is based on the driving of the steam, so that the cooking utensil is not influenced by the material and the structure of the cookware 100, the cookware 100 with different materials and structures is compatible, and the sound frequency generated by the sound generating device 3 is reasonably designed, so that the aims of avoiding most environmental noises and the frequency range of hearing of ordinary people are fulfilled, the interference of environmental factors is avoided in the detection process, and the cooking process is accurately controlled.
The control method of the cooking appliance includes, but is not limited to, water boiling control, stew control, cooking function, dry cooking detection, and the like, and the boiling detection based on water is described as an example below.
Further, step S20 includes:
and controlling the cooking appliance to work according to the signal amplitude of the sound wave signal.
In different cooking scenes, the water in the cooker 100 needs to be stabilized in a high-boiling or slight-boiling state, or the heating main body is controlled to stop heating operation in the high-boiling state, and the high-boiling and slight-boiling state can be distinguished according to the signal amplitude, so that after the sound wave signal is detected and the water is judged to be in the boiling state at present, the high-boiling and slight-boiling are judged according to the signal amplitude.
Further, in one embodiment, the step of controlling the operation of the cooking appliance according to the signal amplitude of the sound wave signal comprises:
s211: comparing the signal amplitude of the sound wave signal with a preset value;
s212: if the signal amplitude is larger than the preset value;
s213: controlling the heating body to reduce power.
For example, when the cooking appliance is in the water boiling function, the cooking appliance starts the water boiling function, the heating main body works to boil water, and when the signal amplitude is greater than the preset value, which corresponds to the signal amplitude value when the water is boiling, and the signal amplitude value is greater than the preset value along with the increase of the temperature of the water, the signal amplitude value indicates that the boiling signal is detected, the heating main body can be controlled to reduce power or even turn off heating, so that the water boiling action is finished.
In the case of performing a stew or steaming function, after the water is boiled, the power of the heating body needs to be adjusted to maintain a slightly boiling state for cooking, and in the case of stew, the step S213 includes:
controlling the heating main body to work at an adjusted first power, wherein the first power is obtained by subtracting a set value from a current power;
it will be appreciated that the adjustment of the frequency of the heating body needs to be made slowly to avoid that too large a single reduction directly brings the water in the pot 100 out of the boiling state, and therefore, the set value should be reduced each time.
When the heating body works at the first power for a first set time length;
it can be understood that, after each adjustment of the power, the power needs to be maintained for a certain period of time to ensure that the detected sound wave signal is in a stable state, and therefore, the first set time is the stable time after the power of the heating body is adjusted.
And acquiring the current signal amplitude of the sound wave signal, and then returning to the step of comparing the signal amplitude of the sound wave signal with a preset value.
I.e. the power reduction is stepwise reduced in dependence on the currently detected signal amplitude, in order to avoid boiling over of the water. For example, when the detected signal amplitude is greater than the preset value, the power of the heating main body is 2000w, a set value is set to be 200w, at this time, during the first adjustment, the power of the heating main body is reduced to 1800w, when the power is stably operated to reach the first set duration, the current signal amplitude is continuously compared with the preset value, if the current signal amplitude is still greater than the preset value, the 200w is continuously reduced on the basis of 1800w to reach 1600w, then the stable operation is continuously operated to reach the first set duration, the step cycle is performed until the current signal amplitude is continuously less than the preset value, and the cycle is stopped.
Further, step S211 is followed by:
if the signal amplitude is smaller than the preset value;
controlling the heating body to maintain the current power to work so as to meet a first preset condition.
It can be understood that, at this moment, it is described that the food material is in a slightly-boiling state, so that the food material can be heated, the soup can be prevented from boiling and overflowing, at this moment, the cooking appliance can start counting down, thereby eliminating the influence of the difference of the food material amount on the soup stewing time, and after the first preset condition is met, the heating main body can be controlled to stop working.
The first preset condition may be a countdown duration of the end of cooking, a state of a degree of cooking of the food, a height of the internal soup, and the like.
In another embodiment, the comparison between the high-boiling parameter and the micro-boiling parameter is required, and the step of controlling the operation of the cooking appliance according to the signal amplitude of the sound wave signal comprises:
comparing the signal amplitude of the sound wave signal with a first preset value;
if the signal amplitude is larger than the first preset value;
controlling the heating main body to reduce power and continuously work for a second set time;
acquiring the current signal amplitude of the sound wave signal;
if the current signal amplitude is smaller than a second preset value, wherein the second preset value is smaller than the first preset value;
and controlling the heating body to maintain the current power to work so as to meet a second preset condition.
For example, the cooking appliance starts a soup stewing function, heats the pot 100 with a larger heating power P1, and when the amplitude of the signal detected by the detection unit is greater than the first preset value, it indicates that the boiling signal is detected and the water is boiled; and controlling the heating main body to reduce power, namely reducing P1, continuously working for the second set time after reducing the power to realize stable heating, acquiring the current signal amplitude until the current signal amplitude is smaller than a second preset value, and indicating that the steam quantity just drops to be lower than the driving threshold of the sounding device 3, the pan is in a micro-boiling state, but the cooking power can be maintained, and the micro-boiling state can be maintained until the cooking is finished.
It should be noted that the second preset condition may be a countdown duration of the cooking end, a cooking state of the food material, a height of the internal soup, and the like, and according to different use functions, the first preset condition and the second preset condition may be the same parameter or different parameters.
Further, the step of obtaining the current signal amplitude of the sound wave signal further includes:
if the current signal amplitude is larger than a second preset value;
and returning to the step of controlling the heating body to reduce the power and continuously work for a second set time period.
That is, the power to the heating body is reduced by gradually reducing the evaporation loss rate, and the gradually reducing manner and the set value thereof may be the same as the previous embodiment.
In addition, in the logic for judging whether the cooking is dry-cooked, the heating main body is controlled to maintain the current power to work so as to meet a second preset condition, the current heating power P2 of the cooking appliance is maintained to heat for a time t1, wherein P2 is less than P1, whether the countdown of the cooking function set by the program of the cooking appliance is finished is confirmed, and if so, the cooking function is finished or the dry-cooked cooking is generated, and the heating main body is controlled to be closed. If not, whether the boiling sound wave signal is continuous or not is detected, whether enough steam quantity can be continuously generated in the country or not can be judged through whether the signal is continuous or not, if the signal is continuous, the moisture degree is indicated, the heating main body can keep the current power to continuously work, if the signal is disconnected, the heating main body is indicated that the steam quantity is insufficient, the cooking function is possibly completed or the dry burning is generated, and the heating main body is controlled to be closed.
