DETAILED DESCRIPTION

[0064] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0066] In an example embodiment, as shown in FIG. 1, the application provides a gas stove control method, and the embodiment is exemplified by the method applied to the controller of the gas stove. It can be understood that the method can also be applied to the terminal or the server, and can also be applied to the system including the terminal and the server, and is realized through the interaction between the terminal and the server. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, etc.; the server can be a stand-alone physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. In the embodiment, the method includes the following steps:

[0067] In step S101, the size information of the pot on the gas stove is acquired.

[0068] In step S102, the horizontal position of the gas collection device is adjusted according to the size information of the pot.

[0069] In step S103, the gas collection device is controlled to collect gas, and the air inlet adjusting device in the gas stove is controlled based on the gas to perform air inlet adjusting operation.

[0070] The size information of the pot can be information representing the size of the pot, for example, the size information of the pot can be diameter information or radius information of the pot.

[0071] The gas collection device can be a device for collecting gas on the gas stove, for example, the gas collection device can be a flue gas probe.

[0072] The horizontal position can be the planar arrangement position of the gas collection device on the gas stove, for example, the horizontal position can be the distance of the gas collection device relative to the burner.

[0073] Optionally, the gas can be flue gas.

[0074] The horizontal movement position information can be information representing the position to which the gas collection device needs to be horizontally moved, for example, the horizontal movement position information can be the distance to which the gas collection device needs to be horizontally moved.

[0075] The horizontal driving device can be a device for driving the gas collection device to move horizontally, for example, the horizontal driving device can be a push rod motor 1.

[0076] The first target position can be the target position to which the gas collection device needs to be horizontally moved.

[0077] The gas information acquired by the gas collection device at the first target position can be information representing the gas collected by the gas collection device at the first target position, for example, can be oxygen content information in the gas collected by the gas collection device at the first target position.

[0078] The damper adjusting device can be a device for adjusting the air intake amount of the gas stove, for example, can be a device composed of a damper gear piece and a damper spring.

[0079] The air intake amount adjusting operation can be an operation of adjusting the air intake amount of the gas stove, for example, can be an operation of adjusting the air intake amount of the gas stove by rotating the damper gear piece driven by the stepper motor.

[0080] Optionally, the controller of the gas stove acquires the size information of the pot on the gas stove; according to the acquired size information of the pot, the optimal gas collection position is calculated, and the horizontal position of the gas collection device is adjusted accordingly; after the horizontal position of the gas collection device is adjusted, the gas collection device starts to collect the gas generated by combustion; the composition and concentration of the collected gas are analyzed, and according to the analysis result, it is determined whether the air intake amount needs to be adjusted, if the air intake amount needs to be adjusted, the damper adjusting device in the gas stove is controlled to perform the corresponding air intake amount adjusting operation.

[0081] For example, the controller of the gas stove acquires the size information of the pot on the gas stove; by querying the corresponding relationship between the preset size information of the pot and the horizontal movement position information, the position information (horizontal movement position information) that the gas collection device needs to move horizontally is determined. The gas stove is also provided with a horizontal driving device in transmission connection with the gas collection device, and the controller can control the horizontal driving device to drive the gas collection device to move horizontally according to the determined position information that the gas collection device needs to move horizontally, until the gas collection device moves horizontally to the first target position corresponding to the horizontal movement position information. After the gas collection device moves horizontally to the first target position, the gas at the first target position can be collected, and the gas information of the collected gas is sent to the controller. The controller can control the damper adjusting device in the gas stove in communication with the burner of the gas stove according to the received gas information of the gas collected by the gas collection device at the first target position, so that the damper adjusting device adjusts the air intake amount of the air intake passage in communication with the burner.

[0082] In the gas stove control method, the size information of the pot on the gas stove is acquired; the horizontal position of the gas collection device is adjusted according to the size information of the pot; the gas collection device is controlled to collect gas, and the air inlet adjusting device in the gas stove is controlled based on the gas to perform air inlet adjusting operation. The scheme adjusts the horizontal position of the gas collection device according to the acquired size information of the pot, which is beneficial to automatically adjusting the gas collection position according to the size of the pot, improving the accuracy of data collection, thereby improving the accuracy of controlling the air inlet adjusting device in the gas stove, realizing the automatic and accurate control of the gas stove, and improving the combustion efficiency and safety of the gas stove.

[0083] In one exemplary embodiment, the following is further included: preset horizontal position information and a corresponding pot size range; adjusting the horizontal position of the gas collection device according to the size information of the pot, specifically including the following: determining the horizontal position information according to the pot size range in which the size information of the pot is located; and controlling the horizontal driving device to operate according to the horizontal position information to adjust the horizontal position of the gas collection device.

[0084] The pot size range can be a plurality of predefined pot size intervals.

[0085] The preset horizontal position information can be pre-set horizontal position information.

[0086] The horizontal position information can be horizontal movement position information, which can be information representing the position at which the gas collection device needs to move horizontally, for example, the horizontal movement position information can be the distance at which the gas collection device needs to move horizontally.

[0087] The horizontal driving device can be a device for driving the gas collection device to move horizontally.

[0088] The driving information can be information for controlling the operation of the horizontal driving device, for example, the driving information can be a displacement value at which the horizontal driving device needs to drive the gas collection device to move horizontally.

[0089] The preset track can be a track in the horizontal direction in which the gas collection device moves, for example, the preset track can be a track installed at a preset position on the bottom surface of the cooktop panel.

[0090] The first distance can be the distance at which the gas collection device needs to move horizontally, for example, the first distance can be a distance value at which the gas collection device needs to move horizontally on the preset track calculated according to the horizontal movement position information.

[0091] Optionally, the controller of the gas stove determines a range of the size of the pot from a plurality of ranges of the size of the pot according to the size information of the pot, and determines the horizontal position information according to the range of the size of the pot, and controls the horizontal driving device to operate according to the horizontal position information, so as to adjust the horizontal position of the gas collection device.

[0092] For example, the controller of the gas stove determines the horizontal target position information according to the size information of the pot, and then compares the horizontal target position information with the horizontal current position information to obtain the distance to be moved by the smoke probe, and then controls the driving device to operate so that the smoke probe moves to the target position (horizontal position) by the distance; then, the horizontal target position information can be used as the horizontal current position information for the next round of comparison calculation, that is, in the next round of comparison calculation, the last position information retained is compared with the horizontal target position information.

[0093] For example, the controller of the gas stove determines the displacement distance that the gas collection device needs to move in the horizontal direction according to the horizontal movement position information; determines the displacement value that the horizontal driving device needs to drive the gas collection device to move in the horizontal direction according to the displacement distance that the gas collection device needs to move in the horizontal direction, and uses the displacement value as the driving information of the horizontal driving device; and controls the horizontal driving device according to the driving information of the horizontal driving device, so that the horizontal driving device drives the gas collection device to move horizontally by the first distance in the preset track, so that the gas collection device moves horizontally to the first target position.

[0094] The technical scheme provided by the embodiment is advantageous in automatically adjusting the horizontal position of the gas collection device, so that the gas collection device can be automatically adjusted to the optimal collection position according to the size of the pot, thereby improving the accuracy of gas collection.

[0095] In an exemplary embodiment, the air intake amount of the gas stove is adjusted by controlling the damper adjustment device, specifically including: detecting the current oxygen content of the gas by an oxygen content sensor; when the current oxygen content is within a preset oxygen content interval, determining the current excess air coefficient of the gas according to the current oxygen content; and controlling the damper adjustment device of the gas stove to adjust the air intake amount according to the current excess air coefficient of the gas.

[0096] The gas collected by the gas collection device at the first target position can be the flue gas generated by the gas stove.

[0097] The oxygen content sensor can be a sensor for detecting the oxygen content in the gas.

[0098] The current oxygen content can be the percentage of oxygen content in the gas collected by the gas collection device at the first target position.

[0099] The preset oxygen content range can be an oxygen content range preset according to the rated power of the gas stove, the type of gas, and other parameters. For example, the preset oxygen content range can be a range less than 14%.

[0100] The current excess air coefficient can be calculated according to the current oxygen content of the gas collected by the gas collection device at the first target position. For example, the current excess air coefficient can be calculated according to the formula α = 21% / (21%-O2'), where α is the current excess air coefficient and O2' is the current oxygen content.

[0101] The process of collecting flue gas through the flue gas probe and analyzing the oxygen content data in the flue gas through the oxygen sensor, and sending the oxygen content data to the data processor to calculate the excess air coefficient, belongs to the prior art, such as the existing flue gas analyzer, including the flue gas analyzer of MRU (Germany's name) with the model of VARIO plus new (enhanced flue gas analyzer).

[0102] Optionally, the controller of the gas stove detects the current oxygen content of the gas through the oxygen content sensor; when it is determined that the current oxygen content is within the preset oxygen content range, the current excess air coefficient of the gas is calculated according to the current oxygen content; and the air inlet adjusting device in the gas stove is controlled to perform the air inlet amount adjusting operation according to the current excess air coefficient of the gas.

[0103] For example, the controller of the gas stove controls the gas collection device to move to the first target position, and then controls the gas collection device to collect gas at the first target position. The oxygen content in the gas collected by the gas collection device at the first target position is detected by the oxygen content sensor to obtain the current oxygen content. It is determined whether the current oxygen content is within the preset oxygen content range. If the current oxygen content is within the preset oxygen content range, the air inlet adjusting device in the gas stove is controlled to perform the air inlet amount adjusting operation according to the current excess air coefficient corresponding to the gas collected by the gas collection device at the first target position. If the current oxygen content is not within the preset oxygen content range, the position of the gas collection device can be adjusted first until the current oxygen content is within the preset oxygen content range, and then the air inlet adjusting device in the gas stove is controlled to perform the air inlet amount adjusting operation according to the current excess air coefficient corresponding to the gas collected by the gas collection device at this time.

[0104] The technical scheme provided by the embodiment is that the current oxygen content is acquired, it is judged whether the current oxygen content is in a preset oxygen content interval, when the current oxygen content is in the preset oxygen content interval, the air intake amount of the damper adjusting device is adjusted according to the current excess air coefficient, which is beneficial to ensuring that the air intake amount is accurately adjusted according to the excess air coefficient when the oxygen content is in the correct interval, avoiding the adjustment error caused by the abnormal oxygen content, thereby being beneficial to improving the accuracy of the damper adjusting device in the gas stove and improving the combustion efficiency and safety of the gas stove.

[0105] In an exemplary embodiment, the operation of adjusting the air intake amount of the damper adjusting device in the gas stove based on the gas further includes the following content: when the current oxygen content is outside the preset oxygen content interval, the vertical position of the gas collection device is adjusted so that the oxygen content sensor detects that the current oxygen content of the gas is in the preset oxygen content interval.

[0106] The vertical position can refer to the position of the gas collection device in the vertical direction.

[0107] The vertical movement position information can be position data required for vertical movement of the gas collection device, for example, the vertical movement position information can be a distance value required for upward or downward movement of the flue gas probe.

[0108] The vertical driving device can be a device for driving the gas collection device to move vertically, for example, the vertical driving device can be a push rod motor 2 for driving the flue gas probe to move vertically.

[0109] The second target position can be a new collection position of the gas collection device after vertical movement, for example, the second target position can be a new collection position of the flue gas probe after upward or downward movement according to the vertical movement position information.

[0110] Optionally, when the controller of the gas stove judges that the current oxygen content is outside the preset oxygen content interval, the vertical position of the gas collection device is adjusted so that the oxygen content sensor detects that the current oxygen content of the gas is in the preset oxygen content interval.

[0111] For example, after obtaining the current oxygen content corresponding to the gas collected by the gas collecting device at the first target position, if it is judged that the current oxygen content is not in the preset oxygen content interval, the controller of the gas stove determines the position information (vertical movement position information) of the vertical movement of the gas collecting device; controls the vertical driving device in the gas stove according to the vertical movement position information, so that the vertical driving device drives the gas collecting device to move vertically to the second target position corresponding to the vertical movement position information, then takes the second target position as a new first target position, jumps to the step of controlling the gas collecting device to collect gas at the first target position, and controls the gas collecting device to collect gas at the new first target position again, and repeats the above steps until the current oxygen content is in the preset oxygen content interval.

[0112] For example, referring to FIG. 2, after obtaining the current oxygen content corresponding to the gas collected by the gas collecting device at the first target position, if it is judged that the current oxygen content is not in the preset oxygen content interval, the controller of the gas stove determines the position information (vertical movement position information) of the vertical movement of the gas collecting device; controls the vertical driving device in the gas stove according to the vertical movement position information, so that the vertical driving device drives the gas collecting device to move vertically to the second target position corresponding to the vertical movement position information, then takes the second target position as a new first target position, jumps to the step of controlling the gas collecting device to collect gas at the first target position, and controls the gas collecting device to collect gas at the new first target position again, and repeats the above steps until the current oxygen content is in the preset oxygen content interval.

[0113] The technical scheme provided by the embodiment is that when the current oxygen content is not in the preset interval, the vertical position of the gas collection device is adjusted, so that the current oxygen content of the gas detected by the oxygen content sensor is in the preset oxygen content interval, which is beneficial to automatically adjusting the position of the gas collection device to obtain correct oxygen content data, thereby improving the judgment accuracy and adjustment timeliness of the combustion state of the gas stove.

[0114] In an exemplary embodiment, the following is further included: determining driving information of the vertical driving device according to the vertical movement position information; and controlling the vertical driving device according to the driving information of the vertical driving device, so that the vertical driving device drives the gas collection device to move vertically by a second distance to a second target position; the second distance is a distance corresponding to the vertical movement position information.

[0115] The driving information of the vertical driving device can be control information for controlling the operation of the vertical driving device.

[0116] The second distance can be the actual distance that the gas collection device moves in the vertical direction, for example, the second distance can be the distance that the gas collection device moves in the vertical direction from the initial position to the second target position.

[0117] Optionally, the controller of the gas stove determines the driving information of the vertical driving device according to the vertical movement position information, wherein the driving information can be a control signal for controlling the operation of the vertical driving device, for example, the control signal can be a pulse signal; and the controller controls the operation of the vertical driving device according to the driving information of the vertical driving device, so that the vertical driving device drives the gas collection device to move vertically by a second distance until the gas collection device reaches a second target position.

[0118] The technical scheme provided by the embodiment is that the driving information of the vertical driving device is determined according to the vertical movement position information, and the vertical driving device drives the gas collection device to move vertically to a second target position according to the driving information, which is beneficial to accurately controlling the vertical position of the gas collection device, thereby improving the accuracy of the combustion state detection of the gas stove.

[0119] In an exemplary embodiment, the damper adjustment device in the gas stove is controlled to perform air intake adjustment operation according to the current excess air coefficient of the gas, specifically including the following: in the case that the current excess air coefficient is less than a first excess air coefficient threshold, the damper adjustment device is controlled to perform air intake increasing adjustment operation; in the case that the current excess air coefficient is greater than a second excess air coefficient threshold, the damper adjustment device is controlled to perform air intake decreasing adjustment operation; the second excess air coefficient threshold is greater than the first excess air coefficient threshold.

[0120] The first excess air coefficient threshold value can be a lower limit threshold value of the excess air coefficient in the combustion state of the gas stove, for example, the first excess air coefficient threshold value can be 1.3.

[0121] The second excess air coefficient threshold value can be an upper limit threshold value of the excess air coefficient in the combustion state of the gas stove, for example, the second excess air coefficient threshold value can be 1.8.

[0122] The increasing air intake adjustment operation can be an operation of the damper adjustment device to increase the air intake of the gas stove, for example, the increasing air intake adjustment operation can be an operation of controlling the step motor to drive the damper gear piece to rotate, thereby increasing the air intake of the gas stove.

[0123] The decreasing air intake adjustment operation can be an operation of the damper adjustment device to decrease the air intake of the gas stove, for example, the decreasing air intake adjustment operation can be an operation of controlling the step motor to drive the damper gear piece to rotate, thereby decreasing the air intake of the gas stove.

[0124] Optionally, after obtaining the current excess air coefficient corresponding to the gas collected by the gas collection device at the first target position, the controller of the gas stove compares the current excess air coefficient with a preset first excess air coefficient threshold value and a second excess air coefficient threshold value, wherein the second excess air coefficient threshold value is greater than the first excess air coefficient threshold value; if the current excess air coefficient is less than the first excess air coefficient threshold value, the damper adjustment device is controlled to perform the increasing air intake adjustment operation; if the current excess air coefficient is greater than the second excess air coefficient threshold value, the damper adjustment device is controlled to perform the decreasing air intake adjustment operation; and if the current excess air coefficient is between the first excess air coefficient threshold value and the second excess air coefficient threshold value, no air intake adjustment operation is needed.

[0125] The technical scheme provided by the embodiment is advantageous in realizing automatic adjustment of the excess air coefficient of the gas stove, ensuring that the gas stove always works in the best combustion condition, and thus is advantageous in realizing the best combustion control of the gas stove.

[0126] In an exemplary embodiment, the increasing air intake adjustment operation of the damper adjustment device includes the following: controlling the damper adjustment driving device to control the damper adjustment device to perform the increasing air intake adjustment operation; and the decreasing air intake adjustment operation of the damper adjustment device includes the following: controlling the damper adjustment driving device to control the damper adjustment device to perform the decreasing air intake adjustment operation.

[0127] The damper adjusting driving device can be a driving device for driving the damper adjusting device to perform the air intake amount adjusting operation, for example, the damper adjusting driving device can be a stepping motor.

[0128] Optionally, the controller of the gas stove determines whether the current excess air coefficient α value is less than a preset first excess air coefficient threshold value according to the calculated current excess air coefficient α value, and if so, controls the damper adjusting driving device to drive the damper gear piece to rotate by a preset angle, thereby increasing the air intake amount of the gas stove until the current excess air coefficient α value reaches a preset range. Similarly, if the controller of the gas stove determines that the current excess air coefficient α value is greater than a preset second excess air coefficient threshold value, it controls the damper adjusting driving device to drive the damper gear piece to rotate by a preset angle, thereby reducing the air intake amount of the gas stove until the current excess air coefficient α value reaches a preset range, wherein the preset range can be a range greater than or equal to the first excess air coefficient threshold value and less than or equal to the second excess air coefficient threshold value, for example, the preset range can be 1.3-1.8.

[0129] The technical scheme provided by the embodiment is advantageous in that the damper adjusting driving device is controlled to control the damper adjusting device to perform the adjusting operation of increasing or reducing the air intake amount, thereby facilitating automatic adjustment of the air intake amount of the gas stove according to the calculated current excess air coefficient, maintaining the current excess air coefficient within a preset optimal range, and thereby facilitating improvement of the combustion efficiency of the gas stove and energy saving.

[0130] In an exemplary embodiment, before adjusting the horizontal position of the gas collection device according to the pan size information, the following is further included: performing flame detection on the gas stove to obtain a flame detection result of the gas stove; and in a case where the flame detection result is that the gas stove has a flame, determining the horizontal movement position information according to the pan size information.

[0131] The flame detection result can be a detection result indicating whether the gas stove has a flame, for example, the flame detection result can be detection result information indicating whether the gas stove has a flame or no flame.

[0132] Optionally, the controller of the gas stove performs flame detection on the gas stove to obtain a flame detection result of the gas stove; and in a case where the flame detection result is that the gas stove has a flame, determines the horizontal movement position information of the gas collection device according to the pan size information.

[0133] For example, the controller of the gas stove can perform flame detection on the gas stove through a flame sensor provided on the gas stove, and when the flame sensor detects that the gas stove has a flame, the horizontal movement position information is determined according to the pan size information.

[0134] The technical scheme provided in the embodiment is beneficial to avoiding determination of the horizontal moving position of the gas collecting device when the gas stove has no flame, thereby being beneficial to improving the accuracy of the determination of the horizontal moving position of the gas collecting device.

[0136] The pot size input page can be an interface for inputting the size information of the pot, for example, the pot size input page can be an interactive interface for inputting the diameter of the pot displayed on the display screen of the gas stove.

[0137] The pot size input instruction can be an instruction for triggering input of the size information of the pot, for example, the pot size input instruction can be an instruction for inputting the size of the pot on the pot size input page.

[0138] Optionally, the controller of the gas stove displays the pot size input page through the display screen of the gas stove, and when the user needs to input the size information of the pot, the user can operate on the pot size input page, for example, input the size information of the pot such as the diameter of the pot through a digital keyboard; the controller of the gas stove receives and responds to the pot size input instruction triggered on the pot size input page to acquire the input size information of the pot.

[0139] The technical scheme provided in the embodiment is beneficial to improving the input convenience and accuracy of the size information of the pot, thereby being beneficial to accurately adjusting the position of the gas collecting device according to the accurate size information of the pot and improving the accuracy of gas collection.

[0140] During the use of the gas stove, a large amount of flue gas will be generated after the gas is burned, and in the calculation work of the gas combustion product (flue gas), the calculation of the excess air coefficient a is often encountered. In the control of the combustion process, it is necessary to detect the excess air coefficient a in the combustion process in time to prevent too much air from being mixed before combustion, increase heat loss and reduce thermal efficiency; at the same time, too little air (excess air coefficient a less than 1) will also worsen the combustion, causing environmental pollution and energy waste. Therefore, during operation, the excess air coefficient a needs to be calculated according to the composition in the flue gas sample, so that measures are taken to automatically adjust the combustion conditions. To ensure the accuracy of the excess air coefficient a, the position of the flue gas collection probe must be accurate, and in the actual use of the gas stove, the size of the cookware selected by the user is uncertain, and the size of the cookware directly affects the position of the flue gas probe. The traditional flue gas probe is fixed in position and cannot be adjusted in time according to the size of the cookware, which ultimately leads to inaccurate data collected by the flue gas probe. The following describes a gas stove control method provided by the present application with an application example. The application example takes the method applied to the controller of the gas stove as an example. Referring to FIG. 3, the main steps include:

[0141] Step 1: The gas stove is powered on, and the controller of the gas stove controls the display screen to light up. The user selects the size of the cookware.

[0142] Step 2: The gas stove is ignited and works, and the controller of the gas stove detects the flame.

[0143] Step 3: If the flame detection result is yes, the controller of the gas stove calculates the moving position of the flue gas probe according to the preset size of the cookware.

[0144] Step 4: The controller of the gas stove controls the push rod motor 1 to start working, and the flue gas probe starts to move horizontally along the preset track until it stops at the preset position.

[0145] Step 5: The controller of the gas stove controls the air pump to start working, and the air sampling is taken. The oxygen content in the collected flue gas is analyzed and calculated by the oxygen content sensor. It is judged whether the oxygen content is less than 14%.

[0146] Step 6: If the oxygen content is greater than or equal to 14%, the controller of the gas stove controls the push rod motor 2 to start working, and the flue gas probe starts to move up and down along the preset track until it stops at the preset position, and jumps to the step of starting the air pump to work and take air sample. If it is judged that the oxygen content is less than 14%, it is judged whether the excess air coefficient is less than 1.3.

[0147] Step 7, if the judgment is that the excess air coefficient <1.3 is yes, then the controller of the gas stove controls the stepper motor to drive the air door adjusting device to rotate the air adjusting plate to increase the air intake. If the judgment is that the excess air coefficient <1.3 is no (i.e. the excess air coefficient is greater than or equal to 1.3), then it is judged whether the excess air coefficient >1.8, if the judgment is that the excess air coefficient >1.8 is yes, then the controller of the gas stove controls the stepper motor to drive the air door adjusting device to rotate the air adjusting plate to reduce the air intake, if the judgment is that the excess air coefficient >1.8 is no, then the air pump, push rod motor, stepper motor, and oxygen content sensor stop working.

[0148] Step 8, after increasing or reducing the air intake, it is judged whether 1.3 < excess air coefficient <1.8, if yes, then the air pump, push rod motor, stepper motor, and oxygen content sensor stop working, if no, then jump to the step of judging whether the excess air coefficient <1.3.

[0149] Among them, referring to Figures 4, 5, 6 and 7, the gas stove comprises the following three parts:

[0150] (1) Smoke probe automatic adjusting mechanism:

[0151] Mechanism composition explanation: this mechanism is mainly composed of a smoke probe (gas collection device), a probe shell (gas collection device shell), a pre-set track (track structure), a push rod motor 1 (horizontal driving device), a push rod motor 2 (vertical driving device), a motor bracket (first bracket structure and second bracket structure), a motor push rod (push rod), etc.

[0152] Assembly position explanation: the track (track structure) is installed at the pre-set position on the bottom surface of the stove panel (panel); the probe shell is sleeved on the smoke probe; the motor bracket 1 (first bracket structure) is transversely installed at the pre-set position on the bottom surface of the stove panel, then the push rod motor 1 is installed in the motor bracket 1, and the push rod is installed in the push rod motor 1; the push rod motor 2 is vertically installed in the motor bracket 2 (second bracket structure), and then the motor bracket 2 is installed in the track.

[0153] Movement principle: after receiving the signal, the push rod motor 1 moves along the vertical direction after the processor calculates the displacement value; after receiving the signal, the push rod motor 2 moves along the horizontal direction after the processor calculates the displacement value.

[0154] (2) Air door automatic adjusting mechanism:

[0155] Mechanism composition explanation: this mechanism is mainly composed of a stepper motor (air door adjusting driving device), a stepper motor bracket (third bracket structure), an air door gear piece, and an air door spring.

[0156] Assembly position description: the damper gear piece is installed at the air inlet of the burner, and is fixed by a nozzle and a damper spring; the stepping motor is installed in a stepping motor support, and the stepping motor support is installed at a fixed position of the burner.

[0157] Rotation principle: after receiving the signal of the data processor, the stepping motor starts to rotate according to the analyzed data, and the pinion (gear structure) at the head of the stepping motor can drive the damper gear piece to start rotating, so as to realize the automatic adjustment function of the air intake at the damper.

[0158] (3) Electric control and data processing module:

[0159] Mainly composed of a display screen controller, an oxygen sensor (oxygen content sensor) and a data processor.

[0160] The formula for calculating the excess air coefficient α is: α = 21% / (21% - O2').

[0161] The value of O2' is provided by the oxygen sensor, and the excess air coefficient α is controlled between 1.3 and 1.8. Based on this, the excess air coefficient α can be calculated by reading the value of O2', in addition, if the oxygen content exceeds 14%, the flue gas probe also needs to move up and down, and then automatically adjust according to the set range.

[0162] The technical scheme provided by the application example realizes automatic adjustment of the position of the flue gas probe according to the size of the pot, so that the detection data is more accurate and reliable; during the use of the gas stove, the excess air coefficient α can be continuously monitored, and the collected data is analyzed and processed in the main chip, and then adjusted by the excess air coefficient α automatic adjustment device, so that the gas stove always works in the best combustion condition.
