Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen appliances, and in particular relates to a stove control method, module, device and a gas stove. Background Art

[0002] Gas stoves are essential appliances for every household, but every year there are fires caused by improper use of gas stoves. In order to prevent fires, relevant technologies have proposed anti-dry-burning gas stoves, which play a protective role when the gas stove has burned the pot. Users still need to replace the pot or clean it with great effort.

[0003] In addition, any discussion of background technology throughout the specification does not mean that the background technology is necessarily the prior art known to technicians in the relevant field, and any discussion of prior art throughout the specification does not mean that the prior art is necessarily widely known or necessarily constitutes common knowledge in the field. Summary of the invention

[0004] The present invention improves the control effect of the stove at least to a certain extent, and can improve the technical effects of preventing the pot from sticking and preventing dry burning.

[0005] In view of this, one object of an embodiment of the present invention is to provide a stove control method; another object of the present invention is to provide a stove control device; another object of the present invention is to provide a stove control module; another object of the present invention is to provide a gas stove.

[0006] In order to achieve the above-mentioned purpose, according to an embodiment of the first aspect of the present invention, there is provided a stove control method, comprising: detecting a current firepower of the stove; if the current firepower reaches a preset firepower, starting multiple timing programs, and when the timing duration of each timing program reaches a preset duration, controlling the stove to output a reminder signal, and controlling the stove to perform a firepower control action corresponding to the timing program.

[0007] Since excessive firepower is an important factor that causes dry burning and pot sticking in a short period of time, the embodiment of the present invention starts multiple timing programs according to whether the firepower reaches a preset firepower. Therefore, the timing for reminder and automatic firepower regulation can be started when there is a high risk factor of dry burning and pot sticking. It can provide early warning to the user and automatically regulate the firepower before dry burning and pot sticking actually occur, thereby protecting the cooking pots on the stove and improving the safety of the stove.

[0008] In combination with the first aspect, in some implementations, detecting the current firepower of the stove includes: detecting the current firepower of the stove when fire adjustment operation information of the user is detected.

[0009] Since the firepower detection of the stove is triggered based on the user's fire adjustment operation information on the stove, the firepower of the stove can be detected in time when the firepower is changed due to user intervention, preventing the stove from being in a high fire state for a long time without being known, thereby improving the protection effect of the cooking utensils used on the stove.

[0010] In combination with the first aspect, in some embodiments, if the user's fire adjustment operation information is detected, the current firepower of the stove is detected, including: after starting the multiple timing programs, if the user's fire adjustment operation information is detected, the current timing program in the multiple timing programs is terminated, and the step of detecting the current firepower of the stove is returned.

[0011] Once the user performs a manual fire adjustment operation to change the fire power of the stove, it indicates that the user is near the stove. By terminating the multiple timing programs that have been started, the reminder signal and the automatic fire adjustment work can be avoided from interfering with the user's cooking operation, thereby achieving flexible switching between automatic and manual fire adjustment.

[0012] In combination with the first aspect, in some embodiments, the stove includes a microswitch, and detecting the current firepower of the stove includes: detecting the number of input signals generated by the microswitch, wherein the fire adjustment operation information is used to control the microswitch so that the microswitch generates an input signal for regulating the firepower of the stove; and judging the current firepower of the stove according to the number of the input signals.

[0013] Thereby, the current firepower of the cooker can be detected without adding any additional sensor devices, thereby realizing convenient and accurate detection of the firepower.

[0014] In combination with the first aspect, in some embodiments, the stove control method also includes: setting a corresponding preset time for each timing program in advance, or detecting the current bottom temperature of the pot when starting the current timing program, and setting a corresponding preset time for the current timing program according to the current bottom temperature of the pot.

[0015] By presetting the preset duration for each timing program, the timing duration of the timing program can be determined more simply and quickly. By setting the preset duration corresponding to the current timing program according to the current pot bottom temperature, the accuracy of the stove firepower control is improved.

[0016] In combination with the first aspect, in some embodiments, the number of the multiple timing programs is pre-set; the controlling the stove to perform a firepower control action corresponding to the timing program includes: if the timing program is the last timing program in the multiple timing programs, then controlling the stove to perform a firepower control action includes controlling the stove to turn off the fire; if the timing program is any other timing program in the multiple timing programs except the last timing program, then controlling the stove to perform a firepower control action includes reducing the firepower of the stove or maintaining the current firepower of the stove.

[0017] By controlling the stove to turn off when the timing time of the last timing program reaches the preset time, the stove is prevented from continuing to work when the user is away from the stove and cannot receive the reminder signal, thereby improving the safety of using the stove.

[0018] In combination with the first aspect, in some embodiments, the firepower control action of controlling the stove to be executed includes reducing the firepower of the stove or maintaining the current firepower of the stove, including: if the timing program is the first target timing program among the other timing programs, then controlling the stove to maintain the current firepower of the stove; if the timing program is the second target timing program among the other timing programs, then controlling the stove to reduce the firepower of the stove, wherein the second target timing program is started after the first target timing program.

[0019] Through different timing programs, different firepower control actions of the stove can be triggered, so as to more accurately control the firepower of the stove and improve the effect of preventing sticking and dry burning.

[0020] In combination with the first aspect, in some embodiments, the firepower control action performed by controlling the stove includes reducing the firepower of the stove or maintaining the current firepower of the stove, including: detecting the current bottom temperature of the pot; if the current bottom temperature of the pot is less than a preset temperature threshold, controlling the stove to maintain the current firepower of the stove; otherwise, controlling the stove to reduce the firepower of the stove.

[0021] Since the fire control action is determined according to the bottom temperature of the cooking pot used on the stove, the fire can be automatically reduced when there is a high risk of dry burning or sticking the pot, thereby improving the accuracy of fire control.

[0022] In combination with the first aspect, in some embodiments, the firepower of the stove includes multiple gears, and when the timing duration of each timing program reaches a preset duration, the stove is controlled to output a reminder signal, and the stove is controlled to perform a firepower adjustment action corresponding to the timing program, including: when the timing duration of the current timing program reaches the corresponding preset duration, the stove is controlled to output a reminder signal, and the stove is controlled to reduce the current firepower by at least one gear, so that after executing multiple timing programs, the stove is controlled to be in an off state.

[0023] Therefore, as soon as each timing program ends, the firepower of the stove is controlled to be reduced by at least one gear until the stove is in an off state, and there is no need to pre-set the number of timing programs. Therefore, the firepower control of the stove is more adaptive.

[0024] In order to achieve the above-mentioned purpose, according to an embodiment of the second aspect of the present invention, there is provided a stove control module, comprising: a firepower detection unit, used to detect the current firepower of the stove; a timing unit, used to start multiple timing programs if the current firepower reaches a preset firepower; a control unit, used to control the stove to output a reminder signal when the timing duration of each timing program reaches a preset duration, and control the stove to perform a firepower regulation action corresponding to the timing program.

[0025] Since excessive firepower is an important factor that leads to dry burning and pot sticking in a short period of time, the embodiment of the present invention starts multiple timing programs according to whether the firepower reaches a preset firepower. Therefore, the timing can be started when there is a high risk factor of dry burning and pot sticking, and a reminder signal is output according to the timing duration to remind the user, and the cooker can be controlled to perform automatic firepower regulation and control actions, thereby providing early warning to the user and automatically adjusting the firepower before actual dry burning and pot sticking, thereby protecting the cooking pots on the cooker when the cooker is in use.

[0033] The firepower determination module is used to determine the current firepower of the cooker according to the number of the input signals.

[0034] In conjunction with the second aspect, in some implementations, the cooker control module further includes:

[0035] The duration setting unit is used to set the corresponding preset duration for each timing program in advance, or

[0036] When the current timing program is started, the current temperature of the pot bottom is detected, and a corresponding preset time length is set for the current timing program according to the current temperature of the pot bottom.

[0037] In conjunction with the second aspect, in some implementations, the number of times of the multiple timing programs is preset; the control unit includes:

[0038] a first control subunit, configured to control the stove to perform a fire control action including controlling the stove to turn off the fire if the timing program is the last timing program among the multiple timing programs;

[0039] The second control subunit is used to control the firepower regulation action performed by the stove to reduce the firepower of the stove or maintain the current firepower of the stove if the timing program is any other timing program among the multiple timing programs except the last timing program.

[0040] In conjunction with the second aspect, in some implementation modes, the second control subunit includes:

[0041] a firepower maintaining module, configured to control the cooker to maintain the current firepower of the cooker if the timing program is the first target timing program among the other timing programs;

[0042] The firepower reduction module is used to control the cooker to reduce the firepower of the cooker if the timing program is the second target timing program among the other timing programs, wherein the second target timing program is started after the first target timing program.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] It should be noted that, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0061] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments may be combined with each other without conflict.

[0062] refer to Figure 1 As shown, a stove control method provided by an embodiment of the present invention is applied to control stoves of the type of gas stoves (such as liquefied gas stoves, coal gas stoves, natural gas stoves, etc.), electromagnetic stoves, etc. The stove control method includes the following steps:

[0063] S100, detecting the current fire power of the stove.

[0064] In the embodiment of the present invention, detecting the current firepower of the stove may be detecting the current effective firepower of the stove, and the current effective firepower may be characterized by the product of the current heat load of the stove and the thermal efficiency. Of course, more simply, the current heat load of the stove may be detected as the current firepower of the stove, without considering the influence of the thermal efficiency on the firepower.

[0065] In fact, depending on the type of stove, the implementation method of detecting its current fire power may also be different:

[0066] Among them, for stoves equipped with micro switches (for example, some gas stoves are equipped with micro switches), the current firepower of the stove can be judged by detecting the number of input signals generated by the micro switches provided on the stove, wherein the number of input signals generated by the micro switches is positively correlated with the firepower of the stove.

[0067] It is understandable that the micro switch needs to be set in linkage with the knob switch of the stove. The rotation of the knob switch will trigger the micro switch to generate an input signal. Different rotation angles of the knob switch will trigger the micro switch to generate different numbers of input signals. Therefore, the stove adjusts the gas flow rate according to the number of input signals, thereby adjusting the firepower of the stove. Therefore, the current firepower of the stove can be determined by detecting the number of input signals generated by the micro switch. In this way, the current firepower of the stove can be detected without adding additional sensors, thereby realizing convenient and accurate detection of firepower.

[0068] For a gas cooker without a micro switch, the current firepower of the cooker can also be detected by other means. For example, the current firepower of the cooker can be determined by directly detecting the rotation angle of the knob switch. Specifically, a position sensor can be provided to detect the rotation angle of the knob switch provided on the cooker; the current firepower of the cooker can be determined based on the corresponding relationship between the rotation angle and the firepower.

[0069] In some implementations, a flow sensor may be provided to detect the gas flow entering the burner, and the current fire power of the stove may be determined based on the corresponding relationship between the gas flow rate and the fire power.

[0070] For an electromagnetic cooker, the current actual power of the electromagnetic cooker can be detected and used to represent its current firepower.

[0071] In the embodiment of the present invention, when the user's fire adjustment operation information is detected, it indicates that the user has manually adjusted the fire power, which may cause the fire power to change, and then triggers the re-detection of the current fire power of the stove. Figure 2 As shown, step S100 may include the following two sub-steps S1001-S1002:

[0072] S1001: Monitor the user's ignition adjustment operation information.

[0073] Among them, the user's fire adjustment operation information is generated according to the user's manual fire adjustment operation, and is used to control the micro switch so that the micro switch generates an input signal for adjusting the fire power of the stove, thereby realizing manual fire power control of the stove and changing the fire power of the stove.

[0074] S1002: When the user's fire adjustment operation information is detected, trigger the detection of the current fire power of the stove.

[0075] Specifically, when the user manually rotates the knob switch on the stove, corresponding fire adjustment operation information will be generated. For example, the fire adjustment operation information may refer to the rotation angle information of the knob switch. The generated fire adjustment operation information will trigger the micro switch to generate a certain number of input signals to adjust the gas flow of the stove, thereby completing the manual adjustment of the firepower of the stove.

[0076] Specifically, the manual rotation operation of the knob switch can be an operation to turn on the gas and ignite the stove, or during the operation of the stove, the manual rotation operation of the knob switch is only used to increase or decrease the fire power, or control the stove to shut down.

[0077] Since the firepower detection of the stove is triggered according to the user's fire adjustment operation information on the stove, the firepower of the stove can be detected in time when the firepower changes, preventing the stove from being in a high fire state for a long time without being known, thereby improving the protection effect of the cooking utensils used on the stove.

[0078] S120: If the current firepower of the stove reaches the preset firepower, multiple timing programs are started, and when the timing duration of each timing program reaches the corresponding preset duration, the stove is controlled to output a reminder signal and to perform a firepower control action corresponding to the timing program.

[0079] In step S120, the preset firepower corresponds to the type of the current firepower, for example, if the detected current firepower is the heat load of the stove, the preset firepower is set to the rated heat load of the stove, or other values ​​set according to the rated heat load, for example, the preset firepower can be set to one-half, two-thirds or three-quarters of the rated heat load, etc. For example, if the detected current firepower is the current effective firepower of the stove, the preset firepower is set to the product of the rated heat load and the thermal efficiency of the stove, or other values ​​set according to the product result.

[0080] When the timing duration of any timing program reaches the corresponding preset duration, the stove will not only be controlled to output a reminder signal, but will also be synchronously controlled to execute the firepower control action corresponding to the timing program, thereby improving the anti-dry burning effect through dual control.

[0081] For an electromagnetic cooker, if the detected current firepower is the current working 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.

[0082] After detecting the current firepower of the stove, it is compared with the preset firepower; if the comparison shows that the current firepower of the stove is greater than or equal to the preset firepower, multiple timing programs are started; if the comparison shows that the current firepower of the stove is less than the preset firepower, the timing program will not be started, but the user will continue to be monitored to see if he has performed a manual fire adjustment operation, so as to detect whether there is any fire adjustment operation information of the user. Once the user's fire adjustment operation information is detected, the current firepower of the stove will be re-detected, and the re-detected current firepower will be compared with the preset firepower.

[0083] It should be noted that, in the embodiment of the present invention, each timing program is set to be performed sequentially: specifically, the next timing program will not be entered until the current timing program ends. Without the intervention of the user's manual ignition adjustment operation, each timing program will be executed sequentially until the timing duration of the last timing program reaches the corresponding preset duration, and the timing process ends.

[0084] Moreover, when the timing duration of the last timing program reaches the corresponding preset duration, the stove will be controlled to turn off the fire to avoid sticking the pot and dry burning, thereby improving the safety of the stove.

[0085] If the user's fire adjustment operation information is detected during the execution of multiple timing programs, it indicates that the user has adjusted the firepower, resulting in an indirect change in the firepower of the stove. If continuing to execute the current timing program is no longer necessary and inaccurate, the current timing program is terminated and returns to step S100 to re-detect the current firepower of the stove.

[0086] Moreover, once the user performs a manual fire adjustment operation to change the fire power of the stove, it indicates that the user is near the stove. By terminating the multiple timing programs that have been started, the reminder signal and the automatic fire adjustment work can be avoided from interfering with the user's cooking operation, thereby achieving flexible switching between automatic and manual fire adjustment.

[0087] When the timing duration of each timing program reaches the corresponding preset duration, the cooker is controlled to output a reminder signal, and the cooker is controlled to perform a firepower control action corresponding to the timing program.

[0088] In the embodiment of the present invention, each time it is determined that the current firepower of the cooker is greater than the preset firepower, the number of times the timing program is started can be a preset fixed number of times. For example, the number of times the timing program is started can be set to 2 times, 3 times, 4 times or 5 times, etc. Then, each time it is detected that the firepower of the cooker reaches the preset firepower, the timing program will be started the same number of times.

[0089] In the embodiment of the present invention, each time it is determined that the current firepower of the stove is greater than the preset firepower, the number of times the timing program is started can also be reset according to the temperature of the bottom of the pot. The temperature of the bottom of the pot and the number of times the timing program is started satisfy a positive correlation. Each time it is detected that the firepower of the stove reaches the preset firepower, the actual number of times the timing program is started will be different due to the current temperature of the bottom of the pot. For example, if the current temperature of the bottom of the pot is A, the timing program is started 3 times. If the current temperature of the bottom of the pot is B (B is greater than A), the timing program is started 2 times. In this way, the stove can be controlled more accurately to improve the effect of preventing the pot from sticking and dry burning.

[0090] In an embodiment of the present invention, the preset duration corresponding to each timing program may be a preset fixed duration, and the fixed durations corresponding to different timing programs may be the same or different. The lengths of the different preset durations set for different timing programs may be positively correlated with the sequence of the timing programs, that is, the longer the preset duration is set for the timing program started first, and the shorter the preset duration is set for the timing program started later, so as to further improve the effect of preventing the pot from getting stuck and burning dry.

[0091] Of course, it is also possible to set corresponding preset durations for each timing program except the last timing program in the order of the timing programs, and set a preset duration longer than the preset durations of the other timing programs for the last timing program. For example, the preset duration set for the last timing program can be set to 5 minutes, while the preset durations set for the other timing programs are shorter than 5 minutes, such as 4 minutes, 3 minutes, etc.

[0092] In some embodiments, for each timing program, when the current timing program is started, the current pot bottom temperature is detected, and the preset duration for the current timing program is set according to the current pot bottom temperature. It is understandable that the pot bottom temperature needs to be inversely related to the preset duration, that is, the higher the current pot bottom temperature, the shorter the preset duration set for the current timing program, so that the risk of burning the pot or dry burning can be reminded and the firepower can be adjusted more timely and accurately.

[0093] More specifically, a curve variation relationship between the pot bottom temperature and the timing duration can be preset, and the preset duration set for the current timing program can be determined from the curve variation relationship according to the current pot bottom temperature. Alternatively, multiple temperature intervals can be divided, and each temperature interval corresponds to a timing duration, so that the preset duration corresponding to the current timing program is determined according to the temperature interval where the current pot bottom temperature is located.

[0094] In the embodiment of the present invention, when the timing duration of each timing program reaches the corresponding preset duration, the control cooker will be triggered to output a reminder signal and control the cooker to perform the firepower control action corresponding to the timing program. The following describes in detail what kind of reminder signal is output and what kind of firepower control action is performed:

[0095] The output reminder signal may include: a voice reminder signal and / or a light reminder signal. In order to ensure the reminder effect, in some embodiments, the output reminder signal at least includes a voice reminder signal, so that the user can be effectively reminded even when the user is away from the stove. Specifically, the voice reminder signal triggered by different timing programs can be a buzzer reminder generated by a buzzer, or a music reminder signal. On the basis of outputting a voice reminder signal, a light reminder signal may also be included, such as a flashing light signal on the panel of the stove, to improve the reminder effect.

[0096] In the embodiment of the present invention, there are at least three types of firepower control actions performed by the stove: (1) reducing the firepower of the stove, (2) maintaining the current firepower of the stove, and (3) controlling the stove to turn off the fire. When the timing duration of any timing program reaches the corresponding preset duration, the stove will be triggered to perform one of the above three firepower control actions.

[0097] Specifically, each time the timing duration of the timing program reaches the corresponding preset duration, the specific firepower control action that will be triggered can be pre-set. Figure 3 As shown, step S102 may specifically include:

[0098] Step S1021: if the timing program is one of the multiple timing programs except the last timing program, the firepower control action executed by the stove includes reducing the firepower of the stove or maintaining the current firepower of the stove;

[0099] Step S1022: If the timing program is the last timing program among multiple timing programs, the firepower regulation action executed by controlling the stove includes controlling the stove to turn off the fire.

[0100] In the embodiment of the present invention, for each timing program other than the last timing program, what kind of firepower control action will be triggered can also be implemented in multiple ways:

[0101] Implementation method 1 may be: for each timing program except the last timing program, when the preset duration corresponding to the current timing program is reached, a fire reduction action relative to the current fire is triggered. The fire reduction amplitude for each execution of the fire reduction action may be the same or different; if different, the fire reduction amplitude for the current fire reduction action may be determined according to the current pot bottom temperature, or, according to the sequence of the timing programs, the corresponding fire reduction amplitudes may be set in advance for each other timing program.

[0102] Implementation method 2 may be: for each timing program except the last timing program, there are at least three times, which can be divided into two categories: a first target timing program and a second target timing program. The second target timing program is started after the first target timing program. There are at least one first target timing program and one second target timing program respectively.

[0103] If the timing program is the first target timing program among the multiple timing programs, the firepower control action executed for the timing program is to maintain the current firepower of the stove; if the timing program is the second target timing program among the multiple timing programs, the firepower control action executed for the timing program is to reduce the firepower of the stove. In this way, in the early stage of cooking, the user is only reminded without automatically intervening in the firepower, while in the late stage of cooking, when the risk of dry burning and pot burning is already high, the firepower of the stove is automatically reduced while reminding the user, so as to control the stove more accurately and improve the effect of preventing dry burning and pot burning.

[0104] Among them, the action of reducing the firepower of the stove can also be determined according to the current temperature of the bottom of the pot to trigger the firepower control action. Multiple temperature intervals can be divided, and a corresponding firepower control action is set for each temperature interval. According to the temperature interval where the current bottom temperature of the pot is located, the corresponding firepower control action is triggered.

[0105] Implementation method three may be: in each timing program except the last timing program, when the corresponding preset time is reached, the current bottom temperature of the pot is detected; if the current bottom temperature of the pot is less than the preset temperature threshold, the current firepower of the stove is maintained; otherwise, the firepower of the stove is reduced.

[0106] If the stove has multiple firepower levels, there is no need to set a fixed number of times to start the timing program. Based on this, step S102 may include: when the timing duration of the current timing program reaches the corresponding preset duration, controlling the stove to output a reminder signal, and controlling the stove to reduce the current firepower by at least one level, so that after executing multiple timing programs, the stove will be in an off state.

[0107] Specifically, the firepower can be reduced by one level when the timing duration of each timing program reaches the corresponding preset duration, or the number of levels by which the firepower is reduced can be different after different timing programs.

[0108] In this embodiment, the number of times the stove is turned off after the firepower is reduced is not constant, but is determined by the firepower before the timing program is started and the number of gears for reducing the firepower each time. Therefore, there is no need to pre-set the number of times the timing program is started. Therefore, the firepower control of the stove is more adaptive and the control effect is better.

[0109] Below, reference Figure 4 Taking a micro switch linked to a knob switch provided on the cooker as an example, the cooker control method provided in the embodiment of the present invention is described by way of example to more clearly understand the technical solution of the present invention:

[0110] First, step S1 is performed: the user rotates the knob switch on the stove to turn on the gas, triggering the micro switch linked with it to generate an input signal for igniting the stove, completing the gas ignition of the stove, and putting the stove into working state.

[0111] Next, the stove control device (e.g., the stove control mainboard) is connected to the micro switch to perform the following steps S2-S13:

[0112] First, step S2 is performed: detecting the number of input signals generated by the micro switch due to user operation.

[0113] Then, execute step S3: determine the current firepower of the stove according to the number of input signals generated by the micro switch, and judge whether the current firepower of the stove is greater than the preset firepower; if so, execute step S4; otherwise, execute step S13.

[0114] Then, step S4 is executed: starting the first timing program.

[0115] Next, execute step S5: determine whether the timing duration of the first timing program reaches the first preset duration, for example: the second preset duration can be 4 minutes, and execute step S6 until the first preset duration is reached.

[0116] Step S6: Control the buzzer to output a first sound reminder signal, start the second timing program and execute step S7.

[0117] Step S7: Determine whether the timing duration of the second timing program reaches the second preset duration, for example, the second preset duration may be 3 minutes, and execute step S8 until the timing duration of the second timing program reaches the second preset duration.

[0118] Step S8: Control the buzzer to output a second sound reminder signal, reduce the firepower of the cooker by one level, and simultaneously start the third timing program and execute step S9.

[0119] The second sound reminder signal may be the same as the first sound reminder signal, or may be different from the first sound reminder signal. For example, the beeping frequency of the second sound reminder signal is higher than the beeping frequency of the first sound reminder signal.

[0120] Step S9: Determine whether the timing duration of the third timing program reaches the third preset duration, for example, the third preset duration may be 2 minutes, and execute step S10 until the timing duration of the third timing program reaches the third preset duration.

[0121] Step S10: controlling the buzzer to output a third sound reminder signal, reducing the firepower of the stove by one level, and simultaneously starting the fourth timing program.

[0122] The third sound reminder signal may be the same as the second sound reminder signal, or may be different from the second sound reminder signal. For example, the beeping frequency of the third sound reminder signal is higher than the beeping frequency of the second sound reminder signal.

[0123] After the fourth timing program is started, step S11 is executed: determining whether the timing duration of the fourth timing program reaches the fourth preset duration, for example, the fourth preset duration can be set to 2 minutes, and step S12 is executed until the timing duration of the fourth timing program reaches the fourth preset duration.

[0124] Step S12: Control the buzzer to output a fourth sound reminder signal, and control the stove to turn off the fire.

[0125] Specifically, the fourth sound reminder signal can be distinguished from the first, second and third sound reminder signals, so that the user knows that the cooker has been controlled to automatically turn off the fire according to the third sound reminder signal.

[0126] During the process of executing steps S4-S12, step S13 is continuously executed: detecting the user's ignition adjustment operation information, and if the user's ignition adjustment operation information is detected, the process of executing steps S4-S12 is terminated and the process returns to step S2.

[0127] Below, reference Figure 5 Taking the input signal of adjusting the firepower of the stove with a micro switch linked to the knob switch provided on the stove as an example, another exemplary description of the stove control method provided in the embodiment of the present invention is given to more clearly understand the technical solution of the present invention:

[0128] First, step S1' is performed: the user rotates the knob switch on the cooker to turn on the gas, triggering the micro switch linked thereto to generate an input signal for igniting the cooker, completing the gas ignition of the cooker, and putting the cooker into working state.

[0129] Next, the stove control device (e.g., the stove control mainboard) is connected to the micro switch to perform the following steps S2'-S8':

[0130] First, step S2' is performed: detecting the number of input signals generated by the micro switch due to user operation.

[0131] Then, execute step S3': determine the current firepower of the stove according to the number of input signals generated by the micro switch, and judge whether the current firepower of the stove is greater than the preset firepower; if yes, execute step S4'; otherwise, execute step 8'.

[0132] Step S4': start a timing procedure.

[0133] Step S5': determine whether the timing duration of the current timing program reaches the corresponding preset duration. If yes, execute step S6'.

[0134] Step S6': controlling the buzzer to output a sound reminder signal, and controlling the firepower of the stove to be reduced by one gear.

[0135] Step S7': determine whether the cooker is currently in an off state; if yes, end the control; otherwise, return to step S4'.

[0136] During the execution of steps S2'-S7', step S8' is continuously executed: the user's ignition adjustment operation information is detected. If the user's ignition adjustment operation information is detected, the execution of steps S2'-S7' is terminated and the process returns to step S2'.
