[0042] In view of the technical problems of inaccurate automatic fire adjustment and low reliability of the related art, the embodiments of the present application provide a gas stove fire power control method, device and gas stove, and the general idea is that: in the process of adjusting the fire power by running the motor, whether the motor is adjusted to the right position is determined by combining the current running time and the current running step number of the motor, even if the motor is out of step due to signal interference and other factors, the motor will not be delayed to stop, because the current running time of the motor is used to assist the determination, so that the inaccurate fire adjustment or the locked rotor caused by the out of step of the motor can be effectively prevented, and the automatic temperature control accuracy and reliability of the gas stove can be improved.

[0043] In order to make the purpose, technical solutions and advantages of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the protection scope of the present application.

[0044] In the first aspect, the embodiments of the present application provide a gas stove fire power control method applied to a gas stove, and the gas stove includes a motor for driving the gas stove to adjust the fire power. Specifically, the motor is rotated by inputting a pulse signal to the motor to drive the rotary knob valve rod of the gas stove to rotate, so as to automatically adjust the fire power of the gas stove.

[0045] Reference Figure 1 As shown in the method for controlling the fire power of the gas stove provided by the embodiments of the present application, the method comprises the following steps:

[0046] S101, a fire control command is acquired, and the fire control command is used to adjust the fire power to a target fire power level.

[0047] In some embodiments, the fire control command can be acquired from an external device through wireless communication, that is, a remote fire control command is acquired, wherein the external device can be a mobile terminal, such as a smart phone, a tablet computer, and the like. The fire control command can be generated based on the operation of a user on the external device, or automatically generated by the external device based on a pre-set cooking program. Unlike the above-mentioned embodiments, the fire control command can also be generated by the gas stove based on a pre-set cooking program. Therefore, the gas stove needs to respond to the fire control command to control the motor of the gas stove to automatically change the fire power level.

[0048] In the embodiments of the present application, the fire control command carries at least a target fire power level, wherein the target fire power level is the fire power level to be adjusted in the current time, and the target fire power level can be any fire power level of the gas stove (including the off position, the minimum fire power level, and the like).

[0049] S102, the motor of the gas stove is started to adjust the fire power according to the fire control command, and the current running time and the current running step number of the motor are monitored during the running of the motor.

[0050] Specifically, in response to the fire control command, a pulse signal is sent to the motor through the position switch, so that the motor outputs a fixed angular displacement corresponding to each pulse signal received by the motor to drive the rotary valve rod to rotate by a certain angle, wherein one or more pulse signals make the motor drive the rotary valve rod of the gas stove to change one fire power level. For example, one or more pulse signals make the motor drive the rotary valve rod to rotate by 30 degrees to change the fire power by one fire power level.

[0051] In the embodiments of the present application, a timer is started when the fire control command is acquired to time the running time of the motor during the running of the motor to obtain the current running time of the motor. The number of pulse signals of the position switch is detected by the single-chip microcomputer to determine the current running step number of the motor.

[0052] S103, whether the current time meets the motor stop condition is judged according to the current running time and the current running step number, and if yes, the motor is controlled to stop to make the fire power adjusted to the target fire power level.

[0053] If the pulse signal of the position switch is lost during the operation of the motor and the single-chip microcomputer cannot detect it, the motor will appear out of step, that is, the motor has actually advanced one or more steps, but the number of pulse signals representing the corresponding number of steps of the motor is not detected. If the current number of steps of the motor is used to determine whether the fire regulation is in place, once the pulse signal representing the number of steps of the motor is lost, the motor will be misjudged and delayed to stop, thereby causing the fire regulation to be too small or too large.

[0054] In the embodiment of the present application, whether the motor stop condition is met at the current time is determined in step S103, including the following steps S1031-S1033:

[0055] S1031: Determine whether the current running duration of the motor at the current time reaches the target duration threshold.

[0056] S1032: Determine whether the number of steps of the motor at the current time reaches the target step threshold.

[0057] If the determination result of any one of S1031 and S1032 is yes, step S1033 is continued to control the motor to stop. Therefore, the motor can be accurately controlled to stop in the case of motor out of step.

[0058] In specific implementation, the above steps S1031 and S1032 can be independent steps, or can be executed in sequence.

[0059] In some embodiments, the motor stop condition needs to be determined before step S103 is executed. Specifically, the current fire position of the gas stove and the target fire position carried by the fire control command are obtained; and the motor stop condition is determined according to the current fire position and the target fire position.

[0060] Specifically, because the amount of fire regulation is different, the threshold information in the motor stop condition is also different. According to the current fire position and the target fire position, the threshold information in the motor stop condition is determined, and the threshold information includes the target duration threshold and the target position threshold. Next, at least two embodiments for determining the target duration threshold and the target position threshold in the motor stop condition are given:

[0061] In some embodiments, the target duration threshold and the target step threshold in the motor stop condition can be determined according to the corresponding relationship between the position change amount and the motor running parameter.

[0062] Specifically, the target duration threshold can be obtained according to the first preset corresponding relationship between the position change amount and the running duration threshold of the motor; and / or the target step threshold can be obtained according to the second preset corresponding relationship between the position change amount and the running step threshold of the motor.

[0063] More specifically, the first preset correspondence and / or the second preset correspondence can be saved in the local storage unit of the gas stove in the form of a relationship table; when the fire control command is obtained, the difference between the current fire power level and the target fire power level is calculated as a target level change amount; the target time threshold and / or the target step threshold corresponding to the target level change amount can be obtained by table lookup.

[0064] Next, referring to Table 1, the relationship table including the first preset correspondence and the second preset correspondence is exemplified:

[0065] Gear change amount Running time threshold Running step threshold Increase / decrease first gear A1 B1 Increase / decrease second gear A2 (A2 > Al) B2 (B2 > Bl) Increase / decrease third gear A3 (A3 > A2) B3 (A3 > B2) Increase / decrease fourth gear A4 (A4 > A3) B4 (A4 > B3) …… …… ……

[0066] Specifically, the running time threshold and / or the running step threshold corresponding to each level change amount of the gas stove can be detected by a test process in advance to construct the first preset correspondence and / or the second preset correspondence; and the first preset correspondence and / or the second preset correspondence are saved in the local storage unit of the gas stove.

[0067] More specifically, the test process is to apply voltages with opposite polarities to both ends of the motor of the gas stove, and let the motor rotate in the forward and reverse directions respectively, so as to respectively detect the running time threshold and the running step threshold corresponding to each level change amount.

[0068] In some other embodiments, for threshold information not obtained by table lookup, other threshold information in the motor stop condition, i.e., the target time threshold and / or the target step threshold, can also be estimated by a calculation model before each execution of step S103.

[0069] Wherein, the target time threshold is estimated by the following process: obtaining the set speed of the motor, the set speed being the speed adopted by the motor during operation; estimating the angular displacement data required by the motor when the fire power of the gas stove changes from the current fire power level to the target fire power level; and estimating the running time required by the motor according to the set speed and the angular displacement data to obtain the target time threshold.

[0070] It should be noted that the set speed of the motor in the embodiment of the application can be a value set before the gas stove is shipped, and therefore the set speed of the motor can be read from the local storage unit of the gas stove.

[0071] For example, the motor generates a specified position increment (in the embodiment of the application, the position increment is angular displacement) for each pulse signal obtained. The number of pulse signals obtained determines the number of motor operation steps, and in turn determines how much the position increment of the motor. The position increment generated by the motor for each pulse signal obtained is used to increase or decrease a firepower level. Thus, the difference between the current firepower level and the target firepower level is calculated, and the angular displacement data generated by the motor to adjust the firepower from the current firepower level to the target firepower level is determined according to the difference.

[0072] Specifically, the target step threshold value can be estimated by the following process: the number of motor operation steps required is estimated according to the current firepower level and the target firepower level to obtain the target step threshold value.

[0073] In a specific implementation, the number of pulse signals required by the motor to change the firepower from the current firepower level to the target firepower level is used as the target step threshold value.

[0074] Further, after the motor is controlled to stop to adjust the firepower to the target firepower level, the current firepower level of the gas stove is updated to the target firepower level for storage, so that the current firepower level of the gas stove can be accurately obtained next time the firepower is automatically adjusted.

[0075] The gas stove firepower control method provided by the embodiment of the application will be described below with reference to Figure 2 to understand the technical solutions of the embodiment of the application:

[0076] Step S1: the gas stove is powered on;

[0077] After step S1, step S2 is performed: the gas stove obtains a firepower adjustment control instruction for adjusting the firepower of the gas stove to a target firepower level;

[0078] After step S2, step S3 is performed: according to the current firepower level and the target firepower level, the corresponding level change amount from the current firepower level to the target firepower level is determined; the target time threshold value and the target step threshold value matching the level change amount are determined;

[0079] After step S3, step S4 is performed: in response to the firepower adjustment control instruction, the motor is started to adjust the firepower of the gas stove, and the timing of the running time of the motor is started;

[0080] After step S4, step S5 is performed: it is judged whether the timing of the running time of the motor reaches the target time threshold value; if yes, it indicates that the firepower is adjusted to the target firepower level, and step S8 is performed; otherwise, step S6 is performed.

[0081] Step S6: the current running step number of the motor is obtained;

[0082] Step S7: judging whether the current running step number of the motor reaches a target step number threshold, if yes, indicating that the fire power is adjusted to the target fire power gear, then executing step S8.

[0083] Step S8: controlling the motor to stop running.

[0084] After step S8, step S9 is executed: updating the current fire power gear of the gas stove.

[0085] Through the above steps S2 to S9, the motor completes a fire power adjustment of the gas stove, and the next time the fire power needs to be adjusted again, the fire power is adjusted again through steps S2 to S9.
