Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
It should be noted that the descriptions related to "first", "second", etc. in the present invention are only used for descriptive purposes and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention will be described in detail below with reference to specific embodiments in conjunction with the accompanying drawings, and it should be noted that the embodiments and features of the embodiments of the present application can be combined with each other without conflict:
referring to fig. 1, a cooker control method provided by an embodiment of the present invention is applied to control cookers of gas cookers (such as a liquefied gas cooker, a natural gas cooker, etc.), electromagnetic cookers, etc., and the cooker control method includes the following steps:
s100, detecting the current firepower of the cooker.
In the embodiment of the invention, the current firepower of the stove can be detected as the current effective firepower of the stove, and the current effective firepower can be characterized by using the product result of the current heat load and the heat efficiency of the stove. Of course, it is simpler to detect the current thermal load of the cooker as the current fire power of the cooker without considering the influence of the thermal efficiency on the fire power.
In fact, according to the type difference of cooking utensils, the implementation mode of detecting its current firepower can also be different:
for a kitchen range provided with a microswitch (for example, some gas ranges are provided with the microswitch), the current firepower of the kitchen range can be judged by detecting the number of input signals generated by the microswitch arranged on the kitchen range, wherein the number of the input signals generated by the microswitch is positively correlated with the firepower of the kitchen range.
It can be understood that the microswitch needs to be in linkage arrangement with a knob switch of the stove, the rotation of the knob switch can trigger the microswitch to generate input signals, and different rotation angles of the knob switch can trigger the microswitch to generate different numbers of input signals, so that the stove correspondingly adjusts the gas flow according to the number of the input signals, and the fire power of the stove is adjusted accordingly. Therefore, the current firepower of the cooker can be judged by detecting the number of input signals generated by the micro switch. Therefore, the current firepower of the cooker can be detected without additionally adding a sensor, and the firepower can be conveniently and accurately detected.
For the gas cooker without the microswitch, the current firepower of the cooker can be detected in other modes. For example, the current fire power of the cooker can be determined by directly detecting the rotation angle of the knob switch. Specifically, a position sensor may be provided for detecting a rotation angle of a knob switch provided on the cooker; and determining the current firepower of the cooker according to the corresponding relation between the rotation angle and the firepower.
In some embodiments, the gas flow entering the burner can be detected by an arranged flow sensor, and the current firepower of the cooker can be determined according to the corresponding relation between the gas flow and the firepower.
For the induction cooker, the current actual power can be used for representing the current firepower of the induction cooker through the detected current actual power of the induction cooker.
In the embodiment of the invention, when the fire adjusting operation information of the user is detected, the fact that the fire is manually adjusted and controlled by the user is indicated, so that the fire is possibly changed, and the current fire of the cooker is triggered to be detected again. Thus, in some embodiments, as illustrated with reference to fig. 2, step S100 may comprise the following two substeps S1001-S1002:
and S1001, monitoring fire adjusting operation information of a user.
The fire adjusting operation information of the user is generated according to the manual fire adjusting operation of the user and is used for controlling the microswitch, so that the microswitch generates an input signal for adjusting and controlling the fire of the cooker, the manual fire adjusting and controlling of the cooker are realized, and the fire of the cooker is changed.
And S1002, triggering and detecting the current firepower of the kitchen range when detecting the information of the fire adjusting operation of the user.
Specifically, a user manually rotates a knob switch arranged on the cooker to generate corresponding fire adjustment operation information, for example, the fire adjustment operation information may refer to rotation angle information of the knob switch, and the generated fire adjustment operation information may trigger the micro switch to generate a certain number of input signals to adjust the gas flow of the cooker, so as to complete manual adjustment of the fire of the cooker.
Specifically, the manual rotation operation of the knob switch may be an on-gas ignition operation of the cooker, or the manual rotation operation of the knob switch is only used for turning up or down the fire power, or controlling the cooker to be turned off during the operation of the cooker.
The fire of the cooker is triggered and detected according to the fire adjusting operation information of the user on the cooker, so that the fire of the cooker can be detected in time when the fire changes, the cooker is prevented from being unknown in a big fire state for a long time, and the protection effect on the cooking utensil used on the cooker can be improved.
And S120, if the current firepower of the cooker reaches the preset firepower, starting a plurality of timing programs, controlling the cooker to output a reminding signal when the timing duration of each timing program reaches the corresponding preset time duration, and controlling the cooker to execute firepower regulation and control actions corresponding to the timing program.
In step S120, the preset fire corresponds to the type of the current fire, such as: if the detected current firepower is the thermal load of the stove, the preset firepower is set as the rated thermal load of the stove, or other values set according to the rated thermal load, such as the preset firepower can be set as one-half, two-thirds or three-fourths of the rated thermal load and the like. For example, if the detected current fire is the current effective fire of the stove, the preset fire is set as the product result of the rated thermal load and the thermal efficiency of the stove, or other numerical values set according to the product result.
When the timing duration of any one time of timing program reaches the corresponding preset duration, the stove can be controlled to output a reminding signal, and the stove can be synchronously controlled to execute the firepower regulation action corresponding to the timing program, so that the dry burning prevention effect is improved through double control.
For an electromagnetic cooker, if the detected current firepower is the current operating power (KM) of the electromagnetic cooker, the preset firepower may be the rated power of the electromagnetic cooker or a related power value set according to the rated power.
After the current firepower of the cooker is detected, comparing the current firepower with the preset firepower; if the current firepower of the cooker is greater than or equal to the preset firepower, starting a plurality of timing programs; if the current firepower of the cooker is smaller than the preset firepower, the timing program is not started, and whether the user performs manual fire adjusting operation is continuously monitored, so that whether the fire adjusting operation information of the user exists or not is detected, once the fire adjusting operation information of the user is detected, the current firepower of the cooker is re-detected, and the re-detected current firepower is compared with the preset firepower.
In the embodiment of the present invention, each timing procedure is set to be performed sequentially: specifically, the next timer procedure is entered after the current timer procedure is finished. And under the condition that the manual fire adjusting operation of a user is not intervened, executing each time of timing program in sequence until the timing duration of the last time of timing program reaches the corresponding preset duration, and ending the timing process.
And when the timing duration of the last timing program reaches the corresponding preset duration, the stove is also controlled to execute fire closing action, so that pot burning and dry burning are avoided, and the use safety of the stove is improved.
If the fire adjusting operation information of the user is detected in the execution process of the timing program for multiple times, the fact that the fire of the cooker is adjusted by the user is represented, and the fire of the cooker is changed in a non-directional manner, if the current timing program is unnecessary and inaccurate after being continuously executed, the current timing program is terminated, and the step S100 is returned to detect the current fire of the cooker again.
And once the user executes the manual fire adjusting operation to change the firepower of the cooker, the user is indicated to be positioned near the cooker, and the interference of the generated reminding signal and the automatic fire adjusting work on the cooking operation of the user can be avoided by stopping the started multiple timing programs, so that the flexible switching between the automatic fire adjusting and the manual fire adjusting is realized.
And when the timing duration of each timing program reaches the preset duration correspondingly set, controlling the stove to output a reminding signal, and controlling the stove to execute a firepower regulation action corresponding to the timing program.
In the embodiment of the invention, the number of times of the started timing program can be preset to be fixed every time the current firepower of the cooker is judged to be larger than the preset firepower. For example, the number of times the timer is started may be set to 2, 3, 4, or 5, and so on. And starting the timing program for the same times when the firepower of the cooker is detected to reach the preset firepower each time.
In the embodiment of the invention, each time the current firepower of the cooker is judged to be greater than the preset firepower, the number of times of starting the timing program can be reset according to the temperature of the cooker bottom, the temperature of the cooker bottom and the number of times of starting the timing program meet a positive correlation relationship, when the firepower of the cooker is detected to reach the preset firepower, the number of times of actually starting the timing program is correspondingly different according to different current temperature of the cooker bottom, for example, if the current temperature of the cooker bottom is A, the timing program is correspondingly started for 3 times, and if the current temperature of the cooker bottom is B (B is greater than A), the timing program is correspondingly started for 2 times, so that the cooker can be controlled more accurately, and the effect of preventing the cooker from being burnt and being dry-burned is improved.
In the embodiment of the present invention, the preset duration correspondingly set for each time counting procedure may be a preset fixed duration, and the fixed durations correspondingly set for different time counting procedures may be the same or different. The length of the preset time length set for different time-counting programs can be positively correlated with the sequence of the time-counting programs, namely: the timing program started first is longer in the preset time period set correspondingly, and the timing program started later is shorter in the preset time period set correspondingly, so that the effects of preventing pot burning and dry burning are further improved.
Of course, the corresponding preset time length may be set only for each of the other timing programs except for the last timing program in the sequence of the timing programs, and the preset time length longer than the preset time lengths of the other timing programs may be set for the last timing program. For example, the preset time period set for the last timer may be set to 5 minutes, and the preset time periods set for the other timers are all shorter than 5 minutes, such as 4 minutes, 3 minutes, and so on.
In some embodiments, for each time counting procedure, when the current time counting procedure is started, the current pot bottom temperature is detected, and the preset duration for the current time counting procedure is set according to the current pot bottom temperature. It will be appreciated that the bottom temperature of the pan needs to be inversely related to the preset time period, namely: the current pot bottom temperature is higher, and the preset time set for the current time timing program is shorter, so that the pot can be burnt more timely and accurately, and the fire can be reminded and regulated and controlled according to the burnt pot and the dry burning risk.
More specifically, a curve change relationship between the pot bottom temperature and the timing duration may be preset, and the preset duration set for the current timing program may be determined from the curve change relationship according to the current pot bottom temperature. Or a plurality of temperature intervals can be divided, each temperature interval corresponds to one timing duration, and therefore the preset duration corresponding to the current timing program is determined according to the temperature interval where the current pot bottom temperature is located.
In the embodiment of the invention, as the timing duration of each timing program reaches the corresponding preset duration, the stove is triggered and controlled to output the reminding signal and control the stove to execute the firepower regulation and control action corresponding to the timing program. In the following, detailed description is given to what kind of reminding signal is output and what kind of fire regulating action is executed:
for the output reminding signal, the following steps can be included: voice reminding signals and/or light reminding signals. In order to ensure the reminding effect, in some embodiments, the output reminding signal at least comprises a voice reminding signal, so that the user can be effectively reminded under the condition that the user is far away from the cooker. Specifically, the voice reminding signals triggered by the timing programs at different times can be buzzing reminding generated by a buzzer or music reminding signals. On the basis of outputting the voice reminding signal, the voice reminding device can further comprise a light reminding signal, for example, a flashing light signal on a panel of the stove, so that the reminding effect is improved.

Specifically, the firepower can be reduced by one gear when the timing duration of each timing procedure reaches the corresponding preset duration, or the number of gears for reducing the firepower can be different after different timing procedures.
In the present embodiment, the range is in the off state after the number of times of the decrease of the heating power required for the range has elapsed, and is not constant but determined according to the heating power before the timer program is started and the number of steps for decreasing the heating power each time, and therefore, the number of times of starting the timer program does not need to be set in advance. Therefore, the self-adaption to the fire control of the cooker is stronger, and the control effect is better.
