[0002] In order to adjust the amount of air entering the burner, gas stoves currently on the market are generally equipped with a damper (also known as an air intake damper) on the air intake pipe below the burner, so that the flame can be manually adjusted to make it burn more stably and evenly, thereby improving combustion efficiency.

[0003] During the installation of gas stoves, engineers will manually adjust the damper in advance according to the stove factory specifications to keep the amount of air entering the burner at the set value. In addition, some users will seal the gas stoves with stickers or glue to prevent water or oil from entering the gas stoves. In the actual use of gas stoves, the fluctuation of intake pressure or unstable gas pressure can easily lead to abnormal flame combustion. The above installation method of gas stoves not only makes it difficult to adjust the damper, but also easily be mistaken by users as poor product quality, thus affecting the user experience.

[0038] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0039] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application, and different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments recorded. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, although the embodiment may not be clearly recorded in the following text.

[0040] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted or added to each example. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, features described in some examples may be combined in other examples.

[0041] It should be emphasized that in the actual use of gas stoves, the mixing ratio between gas and air changes due to the influence of intake pressure fluctuations or unstable gas pressure, which can easily cause abnormal combustion phenomena such as red flame or flame separation. When manually adjusting the air damper opening, on the one hand, users will ask maintenance personnel to adjust it through after-sales service, but the difficulty and time of adjusting the air damper opening will increase due to the inconvenience of disassembling the stove; on the other hand, due to the user's lack of knowledge about flame combustion, users may encounter problems such as ignition failure, flameout or red flame when adjusting by themselves, which may easily make users mistakenly believe that the product quality is poor, thereby affecting the user experience.

[0042] In addition, some users will install gas stoves on built-in closed stoves, or use the integrated stove installation method. Due to insufficient air intake under the stove and gas pressure deviation in various areas, red flames, excessive carbon deposits, incomplete combustion, flame separation or extinction may occur. When manually adjusting the air damper opening, the difficulty and time of adjusting the air damper opening will also increase due to the inconvenience of disassembling the stove.

[0043] Therefore, in order to solve the above-mentioned problem that in the actual use of the gas stove, the flame may be abnormally burned due to the influence of intake pressure fluctuations or unstable gas pressure, and the existing way of installing the gas stove easily makes it very inconvenient to adjust the air door opening, and the user's self-adjustment may also cause problems such as ignition failure, flameout or red flame, which may be mistaken for poor product quality and affect the user's experience. Technical defects, this application will explain the air intake adjustment method of the gas stove in combination with one or more embodiments shown below.

[0044] In an embodiment of the present application, the air intake regulation method of a gas cooker is applied to a gas cooker, which, in addition to conventional structures such as a burner, a gas pipeline (including a valve), an air pipeline, an ignition device, a pot holder and a casing, may also include a control panel, a damper arranged on the air pipeline and a damper regulating device corresponding to the damper, so that the control panel can control the opening of the damper through the damper regulating device to realize automatic regulation of the air intake amount of the air pipeline.

[0045] The control panel can be used to perform conventional control of the gas cooker, such as but not limited to ignition detection control, flameout protection control and timing control, etc., and can also be connected to the damper adjustment device to control the damper adjustment device according to the user's operation instruction, thereby adjusting the damper opening on the air duct. It can be understood that, taking the gas cooker also including a control panel connected to the control panel as an example, the user's operation instruction can be but not limited to the user's operation of the opening adjustment control on the control panel, such as the opening increase instruction obtained by the user selecting the opening increase control on the control panel, or the opening decrease instruction obtained by the user selecting the opening decrease control on the control panel; of course, the gas cooker can also include a communication module for establishing a communication connection with the terminal device as an example, the user's operation instruction can be but not limited to the opening adjustment instruction sent by the user to the gas cooker through the terminal device, such as the user can select the opening increase instruction on the stove third-party application installed on the terminal device, so that the terminal device sends the opening increase instruction to the gas cooker through Bluetooth communication (or wireless LAN communication), and the control panel receives the opening increase instruction, and is not limited to this.

[0046] The opening of the damper can be, but is not limited to, adjusted by two positioning pieces. For example, taking positioning piece 1 and positioning piece 2 as examples, an opening for passing air is provided in the axial region of the damper. The positioning piece 1 can be provided on the surface of the damper and remain stationary, and the positioning piece 2 can be provided on the surface of the damper (for example, between the positioning piece 1 and the damper) and rotate coaxially with the damper. Here, the opening of the damper can be composed of an upper opening and a lower opening that are symmetrically arranged (that is, the upper opening and the lower opening have the same shape). The positioning piece 1 can be used to control the air flow through the upper opening, and the positioning piece 2 can be used to control the air flow through the lower opening. Preferably, the shapes of the positioning piece 1, the positioning piece 2, the upper opening, and the lower opening are all the same.

[0047] It can be understood that, when the damper adjusting device has not yet controlled the damper to rotate, the positioning piece 1 controls the upper opening to prevent air from passing through (it can be understood that the positioning piece 1 completely blocks the upper opening), and the positioning piece 2 controls the lower opening to prevent air from passing through (it can be understood that the positioning piece 2 completely blocks the lower opening), that is, the air pipeline cannot output air to the burner, and the opening of the damper is at the minimum value at this time; after the damper adjusting device controls the damper to rotate, the positioning piece 1 keeps the upper opening from passing through air, and the positioning piece 2 moves with the damper. The air flow through the lower opening is gradually increased by rotating (it can be understood that the blocking area of ​​the lower opening by the positioning piece 2 is gradually reduced), that is, the air pipeline can output air to the gas burner. At this time, the opening of the damper gradually increases, and can be but is not limited to when the positioning piece 2 is rotated to coincide with the position of the positioning piece 1, indicating that the air flow through the lower opening is the largest (it can be understood that the positioning piece 2 cannot block the lower opening, and the positioning piece 2 and the positioning piece 1 completely block the upper opening at the same time), that is, the opening of the damper is the largest at this time.

[0048] It should be noted that the damper, the positioning piece 1 and the positioning piece 2 mentioned above are stove components well known in the art and will not be described in detail here.

[0049] As an option of the embodiment of the present application, the damper adjustment device includes a motor and a gear driven by the motor, the motor is electrically connected to the control board, and a side of the damper close to the damper adjustment device is provided with gear teeth meshing with the gear; or

[0050] The damper regulating device includes an energized coil, a magnet corresponding to the energized coil, and a gear driven by the magnet through a transmission rod. The energized coil is electrically connected to the control panel, and a side of the damper close to the damper regulating device is provided with gear teeth meshing with the gear.

[0051] Specifically, the damper adjusting device may include, but is not limited to, a motor and a gear driven by the motor. Gear teeth meshing with the gear may be provided on the side of the damper close to the damper adjusting device (the side of the damper away from the damper adjusting device may be a smooth surface, i.e., not including gear teeth). The motor is connected to the control board to receive a control signal issued by the control board (for example, taking the motor as a stepping motor, the control signal may be a signal including a specified number of steps) to drive the gear to rotate in a specified direction, thereby enabling the damper and the positioning plate 2 to adjust the damper opening under synchronous rotation. Here, the control signal issued by the control board can be understood as the motor control signal issued by the control board when it first receives the power-on command. The motor control signal can cause the motor drive gear to rotate in a preset direction and at a preset angle, so that when the damper stops rotating, the current opening of the damper can ensure that the air flow passing through is the air flow required for normal combustion of the gas stove; of course, the motor control signal issued by the control board can also be a motor control signal generated according to the user's operating instructions, so that the motor drive gear can rotate in a specified direction and at a specified angle, so that when the damper stops rotating, the current opening of the damper can ensure that the air flow passing through is the air flow that meets the user's adjustment needs.

[0052] In the embodiment of the present application, the type of the motor may be but is not limited to a stepper motor or a DC motor, and the preset direction (or specified direction) may be but is not limited to a clockwise direction or a counterclockwise direction, and is not limited thereto.

[0053] It can be understood that the damper adjusting device may also include an energized coil, a magnet corresponding to the energized coil, and a gear driven by the magnet through a transmission rod. Gear teeth meshing with the gear are provided on the side of the damper close to the damper adjusting device. The energized coil is connected to the control panel to receive the electrical signal sent by the control panel to control the magnet to move linearly in a specified direction, and then drive the gear to rotate through the transmission rod (one end of the transmission rod can be connected to the magnet, and the other end can be connected to the rotating shaft of the gear), so that the damper and the positioning plate 2 can adjust the damper opening under synchronous rotation. It should be noted that when the electrical signal received by the energized coil is consistent with the preset electrical signal threshold, the magnet can maintain its current position, that is, the gear does not rotate at this time; when the electrical signal received by the energized coil is greater than the preset electrical signal threshold, the magnet can be, but is not limited to, moved in a straight line away from the energized coil, thereby causing the gear to rotate in a clockwise direction; when the electrical signal received by the energized coil is less than the preset electrical signal threshold, the magnet can be, but is not limited to, moved in a straight line toward the energized coil, thereby causing the gear to rotate in a counterclockwise direction, thereby achieving adjustment of the damper opening, and is not limited to this.

[0054] Of course, the electrical signal emitted by the control panel may also be the electrical signal emitted by the control panel when it first receives the power-on command. The electrical signal may, but is not limited to, gradually increase to a preset electrical signal threshold, so that when the damper stops rotating, the current opening of the damper can ensure that the air flow passing through is the air flow required for normal combustion of the gas stove; or it may be an electrical signal generated according to a user operation instruction. The electrical signal may, but is not limited to, gradually decrease or gradually increase from a preset electrical signal threshold, so that when the damper stops rotating, the current opening of the damper can ensure that the air flow passing through is the air flow that meets the user's adjustment needs.

[0055] As another optional embodiment of the present application, the damper adjustment device also includes a zero position switch, and the circuit where the zero position switch is located is connected to the control board; when the damper is at the minimum opening, the contact of the zero position switch abuts against the gear teeth at the end of one side of the damper; when the damper is at the maximum opening, the contact of the zero position switch abuts against the gear teeth at the end of the other side of the damper.

[0056] Specifically, in order to ensure the adjustment accuracy of the damper opening, the damper adjustment device may also include a zero-position switch. The circuit where the zero-position switch is located is connected to the control board so that before the control board receives the power-on command for the first time, the contact of the zero-position switch can abut against the gear teeth at the end of one side of the damper. At this time, the zero-position switch is in an off state, that is, the control board cannot detect the high-level signal output by the circuit where the zero-position switch is located, and the damper opening is at the minimum opening; after the control board receives the power-on command for the first time, the damper adjustment device can be controlled to start rotating the damper, and the contacts of the zero-position switch are gradually affected. The pressing action of the gear teeth at the end of one side of the damper causes the zero position switch to switch from an off state to a continuously on state. At this time, the control panel can continuously detect the high-level signal output by the circuit where the zero position switch is located, and the damper opening continues to increase from the minimum opening. When the gear teeth at the end of the other side of the damper abut against the contact of the zero position switch, it indicates that the damper opening is now at the maximum opening. It can then be but not limited to recording the air flow output from the air pipeline to the burner during the process of the damper opening from the minimum opening to the maximum opening, so as to obtain the corresponding relationship between the damper opening and the air flow. Of course, if the damper adjustment device includes the above-mentioned stepper motor and the gear driven by the stepper motor, the control panel here can also but not be limited to obtaining the corresponding relationship between the damper opening and the number of steps of the stepper motor, and is not limited to this.

[0057] It can be understood that after obtaining the correspondence between the damper opening and the air flow, the control panel can also, but is not limited to, control the damper adjustment device to automatically adjust the damper opening according to the correspondence, so that the adjusted damper opening can ensure that the air flow passing through is the air flow required for normal combustion of the gas stove, thereby allowing the user to use the gas stove normally in the future, or automatically adjust the damper opening according to the user's adjustment needs.

[0058] Also see here Figure 1 The structural schematic diagram of a damper and a damper regulating device provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the damper adjusting device includes a zero position switch, a motor and a gear driven by the motor, and gear teeth meshing with the gear are arranged on the side of the damper close to the damper adjusting device, and a positioning piece 1 and a positioning piece 2 are arranged on the surface of the damper (the positioning piece 2 is between the damper and the positioning piece 1, the positioning piece 1 remains fixed, and the positioning piece 2 rotates coaxially with the damper), and an opening for passing air is arranged in the axial area of ​​the damper. It can be seen that the contact of the zero-position switch abuts against the gear teeth at the end of one side of the damper, the positioning piece 1 completely blocks the upper half of the opening, and the positioning piece 2 completely blocks the lower half of the opening. At this time, the air pipeline cannot output air to the burner; as the motor control gear rotates counterclockwise, driving the damper in the clockwise direction, the positioning piece 2 controls the air flow through the lower half of the opening to gradually increase as the damper rotates clockwise, that is, the air pipeline gradually outputs air to the gas burner, and when the gear teeth at the end of the other side of the damper abut against the contact of the zero-position switch, the air flow output by the air pipeline is the largest.

[0059] It should be noted that the first time the power-on command is received mentioned above can be understood as the power-on operation performed by the user on the gas stove after the gas stove is installed (for example, connecting the gas stove to the power supply for the first time). At this time, the control panel can refer to the above embodiment to adjust the opening of the damper, so that the adjusted damper opening can ensure that the air flow passing through is the air flow required for normal combustion of the gas stove, and after detecting the user's ignition operation, it can output air to the burner according to the adjusted damper opening, thereby allowing the flame to burn.

[0060] See next Figure 2 , Figure 2 An overall flow chart of an air intake adjustment method for a gas cooker provided in an embodiment of the present application is shown.

[0061] like Figure 2 As shown, the gas intake adjustment method of the gas cooker may at least include the following steps:

[0062] Step 202: obtaining a first gas parameter corresponding to when the gas pipeline outputs gas, and obtaining a second gas parameter when the gas cooker is burning.

[0063] Specifically, when adjusting the air intake of the gas cooker, the control panel can, but is not limited to, control the gas pipeline to output gas to the burner and the air pipeline to output air to the burner after receiving the ignition operation of the user, so that the burner starts to burn the flame. Here, the amount of gas output from the gas pipeline to the burner can be determined by the fire power level selected by the user or the preset gas pipeline valve opening, and the amount of air output from the air pipeline to the burner can be determined by the air door opening mentioned in the above embodiment.

[0064] It can be understood that when the flame of the gas stove is in an ideal combustion state, there is a standard correspondence between the amount of gas output from the gas pipeline to the burner and other gas parameters of the gas stove (such as but not limited to the pressure value of the mixed gas composed of gas and air output from the mixing pipeline, the thermocouple electromotive force collected by the thermocouple detection circuit, or the flame temperature collected by the infrared detector). The standard correspondence can be obtained through experimental analysis, so that when adjusting the air intake of the gas stove, other gas parameters can be used as signal feedback, so as to judge whether to further fine-tune the air door opening of the gas stove by comparing the difference between the real-time collected values ​​of other gas parameters and the standard values ​​under the ideal combustion state, thereby ensuring that the flame after the fine-tuning operation burns more fully, reduces carbon deposits and has higher energy efficiency.

[0065] Furthermore, the control panel can, but is not limited to, obtain the first gas parameter corresponding to the gas pipeline outputting gas. The first gas parameter can be a pressure value used to indicate the gas pipeline outputting gas. For example, the gas pressure output from the valve to the burner on the gas pipeline can be obtained through a pressure sensor disposed on the gas pipeline (it should be noted that the gas pressure on the gas pipeline also includes the gas pressure output to the gas pipeline, that is, the gas pressure output from the input end of the gas pipeline to the valve). Of course, the first gas parameter in the embodiment of the present application can also be used to indicate the flow value when the gas pipeline outputs gas. For example, the gas flow output from the valve to the burner on the gas pipeline can be obtained through a flow sensor disposed on the gas pipeline.

[0066] In addition, the first gas parameter mentioned above can also be used to indicate the fire power level when the gas pipeline outputs gas. The fire power level can be obtained by the angle rotated by the user on the fire power knob set on the gas stove. For example, after the control panel detects the rotation angle of the fire power knob, it can determine the fire power level corresponding to the rotation angle according to the preset rotation angle-level correspondence relationship; or, the fire power level can also be obtained by the level command input by the user on the control panel set on the gas stove. For example, the control panel can directly determine the fire power level according to the level command, and is not limited to this.

[0067] Furthermore, after obtaining the first gas parameter, the control panel can also obtain the second gas parameter when the gas cooker is burning. Here, the type of the second gas parameter can be determined according to the type of the first gas parameter. For example, when the first gas parameter is a pressure value indicating the gas pipeline outputting gas, the second gas parameter can be a pressure value indicating the mixed gas composed of gas and air output by the gas mixing pipeline when the gas cooker is burning. One end of the gas mixing pipeline can be connected to the output end of the gas pipeline and the output end of the air pipeline respectively, and the other end can be connected to the burner to fully mix the gas and air. The pressure sensor arranged between the gas mixing pipeline and the burner collects and feeds back to the control panel, that is, the mixed gas pressure is used as a signal feedback, and the difference between the mixed gas pressure and the corresponding standard value is compared to determine whether to further fine-tune the air door opening of the gas cooker, thereby ensuring more complete flame combustion, reducing carbon deposition and higher energy efficiency. Of course, the first gas parameter in the embodiment of the present application can also be used to indicate the flow value when the gas pipeline outputs the gas, and the second gas parameter can be used to indicate the flow value of the mixed gas output from the mixing pipeline to the burner, and is not limited to this.

[0068] It should be noted that when the flame burns more fully, the flame temperature will be relatively high. At this time, the mixed gas pressure output by the pressure sensor is relatively high, and the mixed gas pressure output by the pressure sensor is different under different gas pressures; when the flame appears reddish or has abnormal phenomena such as flame separation, the flame temperature will change. At this time, the mixed gas pressure output by the pressure sensor will also change. The difference between the mixed gas pressure output at this time and the corresponding standard mixed gas pressure can be combined to further fine-tune the damper opening.

[0069] When the first gas parameter is used to indicate the fire level when the gas pipeline outputs gas, the second gas parameter may be used to indicate the thermocouple electromotive force when the gas stove is burning. The thermocouple electromotive force may be collected by the thermocouple detection circuit of the gas stove and output to the control board, that is, the thermocouple electromotive force is used as a signal feedback, and the difference between the thermocouple electromotive force and the corresponding standard value is compared to determine whether to further fine-tune the air door opening of the gas stove, thereby ensuring that the flame burns more fully, reduces carbon deposits and has higher energy efficiency.

[0070] It should be noted that when the flame burns more fully, the flame temperature will be relatively high. At this time, the thermocouple electromotive force output by the thermocouple detection circuit is relatively high, and the thermocouple electromotive force output by the thermocouple detection circuit is different at different firepower levels; when the flame appears abnormal phenomena such as reddish or flame separation, the flame temperature will change, and the thermocouple electromotive force output by the thermocouple detection circuit will also change. Then, the difference between the thermocouple electromotive force output at this time and the corresponding standard electromotive force can be combined to further fine-tune the air door opening. Here, the thermocouple detection circuit of the gas cooker can be a gas cooker structure well known in the art, but it will not be described in detail here.

[0071] When the first gas parameter is used to indicate the fire level when the gas pipeline outputs gas, the second gas parameter can also be used to indicate the flame temperature of the gas stove when it is burning. The flame temperature can be collected by an infrared detector arranged near the burner of the gas stove and output to the control board, that is, the flame temperature is used as a signal feedback, and the difference between the flame temperature and the corresponding standard value is compared to determine whether to further fine-tune the air door opening of the gas stove, thereby ensuring that the flame burns more fully, reduces carbon deposits and has higher energy efficiency.

[0072] It should be noted that the infrared detector can use the optical signal of flame radiation to realize flame detection. When a flame is generated, the flame will emit infrared light of a certain wavelength. At this time, the infrared detector captures the infrared light signal of the natural flame and the flame combustion process, and then converts the signal into an electrical signal for processing. Here, when the flame burns more fully, the flame temperature will be relatively high, and the flame temperature output by the infrared detector is different at different firepower levels; when the flame appears reddish or off-flame and other abnormal phenomena, the flame temperature will change, and the flame temperature output by the infrared detector will also change. Then, the difference between the flame temperature output at this time and the corresponding standard flame temperature can be combined to further fine-tune the damper opening, and the infrared detector in the embodiment of the present application belongs to a detection component well known in the art, but the relevant control principles will not be elaborated.

[0073] As another option of the embodiment of the present application, please refer to Figure 3 An overall flow chart of another gas cooker air intake adjustment method provided in an embodiment of the present application is shown.

[0074] like Figure 3 As shown, the gas intake adjustment method of the gas cooker may at least include the following steps:

[0075] Step 302, obtaining a first gas parameter corresponding to when the gas pipeline outputs gas, and the control panel controls the damper adjustment device to perform a second fine-tuning operation on the damper opening based on the first gas parameter, so that the damper opening is adjusted to a second opening indicated by the second fine-tuning operation.

[0076] During the use of the gas cooker, the amount of gas supplied at different times of use may be different. For example, the amount of gas supplied at peak times of gas use may be insufficient, or the amount of gas supplied at low times of gas use may be sufficient, which results in the amount of gas output to the gas pipeline fluctuating. Based on this, the air flow output from the damper to the burner can be controlled according to the amount of gas output to the burner in real time from the gas pipeline, so that the air flow can be reduced by fine-tuning the damper opening when the gas pressure is insufficient, or the air flow can be increased by fine-tuning the damper opening when the gas is sufficient, so that the flame burns more fully during the combustion process and prevents the occurrence of flame separation and other phenomena.

[0077] Specifically, the control panel can, but is not limited to, determine the air flow required for the flame to burn fully at this time according to the first gas parameter, and can control the damper adjustment device to perform a second fine-tuning operation on the current opening of the damper according to the air flow, so that the current opening of the damper is adjusted to the second opening indicated by the second fine-tuning operation, so that the flame is not affected by the fluctuation of the gas pressure in the gas pipeline during combustion, and the combustion is more complete. Here, the second fine-tuning operation can be understood as an operation to increase the opening or an operation to decrease the opening. For example, the control panel can calculate the difference between the air flow required for the flame to burn fully at present and the air flow corresponding to the current opening of the damper. When the difference result is less than zero, it can be indicated as an operation to decrease the opening, and the opening required to be decreased at this time can be determined based on the difference result and the above-mentioned correspondence between the damper opening and the air flow; when the difference result is greater than zero, it can be indicated as an operation to increase the opening, and the increased opening can also be determined based on the difference result and the above-mentioned correspondence between the damper opening and the air flow; when the difference result is equal to zero, it can be indicated that the first fine-tuning operation is not required.

[0078] On this basis, the second opening indicated by the second fine-tuning operation can be the sum of the damper opening when the flame starts to burn and the required increased opening, or the difference between the damper opening when the flame starts to burn and the required reduced opening.

[0079] As another option of the embodiment of the present application, the control panel controls the damper adjustment device to perform a second fine-tuning operation on the opening of the damper based on the first gas parameter, so that the opening of the damper is adjusted to a second opening indicated by the second fine-tuning operation, including:

[0080] The control panel determines the fine-tuning opening corresponding to the first gas parameter in a preset parameter-opening correspondence table; wherein the preset parameter-opening correspondence table includes at least two groups of gas parameter intervals and the standard opening corresponding to each group of gas parameter intervals;

[0081] The damper adjustment device is controlled to perform a second fine-tuning operation on the damper opening according to the fine-tuning opening, so that the damper opening is adjusted to a second opening indicated by the second fine-tuning operation.

[0082] Specifically, the control panel can query the standard opening (i.e., the second opening) corresponding to the first gas parameter in the preset parameter-opening correspondence table, and use the absolute value of the difference between the standard opening and the current opening of the damper as the fine-tuning opening. Here, the preset parameter-opening correspondence table includes multiple groups of gas parameter intervals and the standard opening corresponding to each group of gas intervals. The multiple groups of gas parameter intervals can effectively control the adjustment frequency of the damper adjustment device during the fine-tuning operation, so as to realize automatic fine-tuning of the gas cooker in combination with the fine-tuning opening determined by the first gas parameter.

[0083] See here Figure 4 A schematic diagram of a preset parameter-opening correspondence table provided in an embodiment of the present application is shown, such as Figure 4 As shown, when the first gas parameter is a pressure value for indicating the gas pipeline outputting gas, the preset parameter-opening correspondence table may include five groups of gas pressure intervals, and the standard opening corresponding to each group of gas pressure intervals (i.e. Figure 4 The air damper opening in the table is, for example, but not limited to, when the first gas parameter is in the gas pressure range [p3-p4], the corresponding standard opening can be Q3, and is not limited to the number of gas pressure range groups included in the preset parameter-opening correspondence table. In the embodiment of the present application, p1 can be, but not limited to, 150Pa, p2 can be, but not limited to, 450Pa, p3 can be, but not limited to, 800Pa, p4 can be, but not limited to, 1200Pa, and p5 can be, but not limited to, 1500Pa, and is not limited thereto.

[0084] Also see here Figure 5 A schematic diagram of another preset parameter-opening correspondence table provided in an embodiment of the present application is shown, such as Figure 5 As shown, when the first gas parameter is used to indicate the fire power level when the gas pipeline outputs gas, the preset parameter-opening correspondence table may include five fire power levels and the standard opening corresponding to each group of fire power levels (i.e. Figure 5 The air damper opening in the figure), for example but not limited to when the first gas parameter is the third gear fire gear, the corresponding standard opening can be Q3, and is not limited to the number of gas pressure interval groups contained in the parameter-opening correspondence table preset here.

[0085] It can be understood that when the difference between the standard opening and the current opening of the damper is less than zero, it indicates that the second fine-tuning operation is an operation to reduce the opening; when the difference between the standard opening and the current opening of the damper is greater than zero, it indicates that the second fine-tuning operation is an operation to increase the opening, and then the control panel can control the damper adjustment device to perform the second fine-tuning operation on the current opening of the damper according to the fine-tuning opening, so that the current opening of the damper is adjusted to the second opening indicated by the second fine-tuning operation, thereby ensuring that the flame is not affected by the fluctuation of the gas pressure in the gas pipeline during combustion, and the combustion is more complete.

[0086] Step 204: The control panel controls the damper adjustment device to perform a first fine-tuning operation on the damper opening according to the first gas parameter and the second gas parameter, so that the damper opening is adjusted to a first opening indicated by the first fine-tuning operation.

[0087] Specifically, after obtaining the first gas parameter and the second gas parameter, the control panel can, but is not limited to, determine the standard parameter corresponding to the first gas parameter in a preset parameter list. The type of the standard parameter can be consistent with the type of the second gas parameter, and can determine whether it is necessary to further fine-tune the current opening of the damper (which may be the second opening mentioned above) based on the absolute value of the difference between the standard parameter and the second gas parameter. When it is determined that the current opening of the damper needs to be fine-tuned, the damper adjustment device is controlled to perform a first fine-tuning operation on the current opening of the damper, so that the opening of the damper is adjusted to the first opening indicated by the first fine-tuning operation, thereby ensuring that the flame burns more fully, reduces carbon deposits and has higher energy efficiency.

[0088] Here, taking the first gas parameter as an example of a pressure value indicating the gas pipeline outputting gas, and the second gas parameter as an example of a pressure value indicating the mixed gas composed of gas and air outputted from the mixing pipeline when the gas cooker is burning, the preset parameter list can be understood as a preset gas-mixed gas correspondence list, which includes multiple groups of gas pressure intervals and a standard mixed gas pressure corresponding to each group of gas pressure intervals. The standard parameter here is the standard mixed gas pressure corresponding to the gas pressure interval in which the first gas parameter is located.

[0089] Here, taking the first gas parameter as an example of indicating the fire level when the gas pipeline outputs gas, and the second gas parameter as an example of indicating the thermocouple electromotive force when the gas stove is burning, the preset parameter list can be understood as a preset gas-electromotive force correspondence list, which includes multiple groups of gas pressure intervals and the standard electromotive force corresponding to each group of gas pressure intervals. The standard parameter here is the standard electromotive force corresponding to the gas pressure interval in which the first gas parameter is located.

[0090] Here, taking the first gas parameter as an example of indicating the fire level when the gas pipeline outputs gas, and the second gas parameter as an example of indicating the flame temperature of the gas stove when burning, the preset parameter list can be understood as a preset gas-flame temperature correspondence list, which includes multiple groups of gas pressure intervals and the standard flame temperature corresponding to each group of gas pressure intervals. The standard parameter here is the standard flame temperature corresponding to the gas pressure interval in which the first gas parameter is located.

[0091] It can be understood that when judging whether it is necessary to further fine-tune the current opening of the damper (which may be the second opening mentioned above) based on the absolute value of the difference between the standard parameter and the second gas parameter, it can be, but is not limited to, when it is detected that the absolute value of the difference is less than or equal to the preset deviation threshold, indicating that the flame is burning more fully at this time, and the current opening of the damper can be controlled by the control panel to be maintained at the second opening indicated by the second fine-tuning operation mentioned above.

[0092] Here, the preset deviation threshold mentioned can be determined according to the type of the standard parameter or the second gas parameter. For example, when the type of the standard parameter or the second gas parameter is gas pressure, the preset deviation threshold may be a preset gas pressure deviation threshold; when the type of the standard parameter or the second gas parameter is electromotive force, the preset deviation threshold may be a preset electromotive force deviation threshold; when the type of the standard parameter or the second gas parameter is temperature, the preset deviation threshold may be a preset flame temperature deviation threshold.

[0093] When it is detected that the absolute value of the difference is greater than the preset deviation threshold, it indicates that the flame is not in a fully burning state at this time. Then, when it is detected that the difference between the standard parameter and the second gas parameter is less than zero, it is determined that the first fine-tuning operation is an operation to reduce the opening. At this time, the opening to be reduced can be but not limited to the preset fine-tuning opening threshold. The control panel can control the damper adjustment device to perform a fine-tuning operation on the current opening of the damper according to the first fine-tuning operation and the preset fine-tuning opening threshold, so that the opening of the damper is fine-tuned to the first opening indicated by the first fine-tuning operation. The first opening is the current opening of the damper. The difference result between the opening and the preset fine-tuning opening threshold; when it is detected that the difference between the standard parameter and the second gas parameter is greater than zero, it is determined that the first fine-tuning operation is an operation to increase the opening. At this time, the opening required to be increased can be but is not limited to the preset fine-tuning opening threshold, and the control panel can control the damper adjustment device to perform fine-tuning operation on the current opening of the damper according to the first fine-tuning operation and the preset fine-tuning opening threshold, so that the opening of the damper is fine-tuned to the first opening indicated by the first fine-tuning operation, and the first opening is the sum of the current opening of the damper and the preset fine-tuning opening threshold.

[0094] For example, but not limited to, taking the type of the second gas parameter as gas pressure as an example, when the absolute value of the difference between the obtained mixed gas pressure and the standard mixed gas pressure is less than or equal to the preset gas pressure deviation threshold, there is no need to fine-tune the damper opening; when the absolute value of the difference is greater than the preset gas pressure deviation threshold, if the standard mixed gas pressure is less than the mixed gas pressure, the damper opening is fine-tuned to decrease; if the standard mixed gas pressure is greater than the mixed gas pressure, the damper opening is fine-tuned to increase.

[0095] Or taking the type of the second gas parameter as electromotive force as an example, when the absolute value of the difference between the obtained thermocouple electromotive force and the standard electromotive force is less than or equal to the preset electromotive force deviation threshold, there is no need to fine-tune the damper opening; when the absolute value of the difference is greater than the preset electromotive force deviation threshold, if the standard electromotive force is smaller than the thermocouple electromotive force, the damper opening is fine-tuned to decrease; if the standard electromotive force is greater than the thermocouple electromotive force, the damper opening is fine-tuned to increase.

[0096] Or taking the flame temperature as an example, when the absolute value of the difference between the obtained flame temperature and the standard flame temperature is less than or equal to the preset flame temperature deviation threshold, there is no need to fine-tune the damper opening; when the absolute value of the difference is greater than the preset flame temperature deviation threshold, if the standard flame temperature is less than the obtained flame temperature, the damper opening is fine-tuned to decrease; if the standard flame temperature is greater than the obtained flame temperature, the damper opening is fine-tuned to increase.

[0097] Of course, the fine-tuning opening threshold preset in the embodiment of the present application can also be determined based on a preset deviation threshold. For example, but not limited to, when the preset deviation threshold is in a certain deviation interval, the opening threshold corresponding to the deviation interval can be used as the preset fine-tuning opening threshold, and is not limited to this.

[0098] See next Figure 6 , Figure 6 The figure shows an overall flow chart of another gas cooker air intake adjustment method provided in an embodiment of the present application.

[0099] like Figure 6 As shown, the gas intake adjustment method of the gas cooker may at least include the following steps:

[0100] Step 602: The control panel controls the damper adjustment device to adjust the damper opening according to the received user operation instruction, so that the damper opening reaches the third opening indicated by the user operation instruction.

[0101] Specifically, when adjusting the air intake of the gas cooker, in order to ensure that the flame of the gas cooker is in a normal combustion state when it starts to burn, so as to effectively avoid the difficulty of disassembling the gas cooker to adjust the air damper opening, before obtaining the first gas parameter corresponding to the gas output of the gas pipeline, the control panel can, but is not limited to, control the air damper adjustment device to automatically adjust the first opening of the air damper according to the user operation instruction obtained from the user terminal or the control panel, so that the adjusted air damper opening reaches the third opening indicated by the user operation instruction, thereby ensuring that the flame is in a normal combustion state.

[0102] Here, the third opening indicated by the user operation instruction can be determined based on the user operation instruction and the current opening of the damper (which can be but is not limited to the default opening of the gas stove to ensure that the air flow passing through is the air flow required for normal flame combustion). For example, when the user operation instruction is indicated as an instruction to increase the opening, the sum of the current opening of the damper and the preset opening threshold can be used as the third opening indicated by the user operation instruction; or when the user operation instruction is indicated as an instruction to decrease by one degree, the difference between the current opening of the damper and 1 can be used as the third opening indicated by the user operation instruction, and is not limited to this.

[0103] It should also be noted that in the embodiment of the present application, the control panel can also directly control the damper adjustment device to adjust the opening of the damper according to the received user operation instructions after the flame starts to burn, and is not limited to this.
