Description

Technical Field

[0001] This application belongs to the field of stove control technology, and specifically relates to a gas stove intake adjustment method and a gas stove. Background Technology

[0002] In order to regulate the amount of air entering the burner, gas stoves on the market generally have an air damper (also known as an air intake damper) installed on the air intake pipe below the burner. This allows for manual adjustment to make the flame burn more stably and evenly, thereby improving combustion efficiency.

[0003] During the installation of gas stoves, engineers manually adjust the air damper according to the stove's factory specifications to ensure the amount of air entering the burner remains at the set value. Some users also seal the area around the gas stove with stickers or adhesive to prevent water or oil from entering. However, in actual use, fluctuations in intake pressure or unstable gas pressure can easily lead to abnormal flame combustion. The aforementioned installation methods not only make air damper adjustment difficult but also mislead users into believing the product is of poor quality, thus negatively impacting the user experience. Summary of the Invention

[0004] This application addresses the aforementioned technical shortcomings of gas stoves, such as the susceptibility to abnormal flame combustion due to fluctuations in intake pressure or unstable gas pressure during actual use, the difficulty in adjusting the air damper caused by the aforementioned installation method, and the potential for users to mistakenly perceive the product as of poor quality, thus affecting the user experience. The application proposes an intake adjustment method and a gas stove, the technical solution of which is as follows:

[0015] The control panel determines the standard parameter corresponding to the first gas parameter from a preset parameter list; wherein the preset parameter list includes at least two gas parameter ranges and the standard parameter corresponding to each gas parameter range.

[0016] Based on the absolute value of the difference between the standard parameter and the second gas parameter, the damper adjustment device is controlled to perform a second fine-tuning operation on the damper opening, so that the damper opening is adjusted to the third opening indicated by the second fine-tuning operation.

[0017] In another alternative to the first aspect, the damper regulating device is controlled to perform a second fine-tuning operation on the damper opening based on the absolute value of the difference between the standard parameter and the second gas parameter, so that the damper opening is adjusted to a third opening indicated by the second fine-tuning operation, including:

[0018] When the absolute value of the difference is detected to be less than or equal to the preset deviation threshold, the opening of the control damper is maintained at the second opening indicated by the first fine-tuning operation.

[0019] When the absolute value of the difference is detected to be greater than the preset deviation threshold, the damper adjustment device is controlled to perform a second fine-tuning operation on the opening of the damper so that the opening of the damper is adjusted to the third opening indicated by the second fine-tuning operation.

[0040] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] In the following description, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The following description provides multiple embodiments of this application, which can be substituted or combined with each other. Therefore, this application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then this application should also be considered to include embodiments containing one or more other possible combinations of A, B, C, and D, even if such embodiments are not explicitly described in the following text.

[0042] 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 function and arrangement of the described elements without departing from the scope of this application. Various processes or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined into other examples.

[0043] It is important to emphasize that during the actual use of gas stoves, fluctuations in intake pressure or unstable gas pressure can alter the gas-air mixture ratio, easily causing abnormal combustion phenomena such as a reddish flame or flame lift-off. When manually adjusting the air damper opening, users may seek assistance from after-sales service personnel, but the difficulty and time involved in adjusting the damper opening due to the inconvenience of disassembling the stove can increase the difficulty of adjustment. Furthermore, users' lack of knowledge about flame combustion can lead to problems such as ignition failure, flameout, or a reddish flame when adjusting the damper themselves, which can easily cause users to mistakenly believe that the product quality is poor, thus affecting the user experience.

[0044] In addition, some users install gas stoves on built-in enclosed cooktops or use integrated cooktops. Due to insufficient air intake under the cooktop and gas pressure deviations in different areas, phenomena such as red flames, excessive carbon buildup, incomplete combustion, flame lift-off, or flameout may occur. When manually adjusting the air damper opening, the difficulty and time required for adjustment are also increased due to the inconvenience of disassembling the cooktop.

[0045] Therefore, in order to address the aforementioned technical defects in gas stoves, such as abnormal flame combustion caused by fluctuations in intake pressure or unstable gas pressure during actual use, the inconvenience of adjusting the air damper opening in existing gas stove installation methods, and the fact that user self-adjustment can lead to ignition failure, flameout, or red flame, which may be mistakenly perceived as poor product quality and affect user experience, this application will explain the gas intake adjustment method of gas stoves in conjunction with one or more embodiments shown below.

[0046] In this embodiment, the gas stove intake adjustment method is applied to a gas stove. In addition to conventional structures such as burners, gas pipelines (including valves), air pipelines, ignition devices, cookware supports, and outer shells, the gas stove may also include a control board, an air damper installed on the air pipeline, and an air damper adjustment device corresponding to the air damper. The control board controls the opening of the air damper through the air damper adjustment device to achieve automatic adjustment of the air intake volume of the air pipeline.

[0047] The control board can be used to perform routine controls of the gas stove, such as, but not limited to, ignition detection control, flameout protection control, and timer control. It can also be connected to an air damper adjustment device to control the device according to user commands, thereby adjusting the air damper opening in the air duct. For example, if the gas stove also includes a control panel connected to the control board, the user commands can be, but are not limited to, commands obtained by the user manipulating the opening adjustment controls on the control panel. For instance, it could be an opening increase command based on the user's selection of an opening increase control on the control panel, or an opening decrease command based on the user's selection of an opening decrease control on the control panel. Alternatively, the gas stove can also include a communication module for establishing a communication connection with a terminal device. In this case, the user commands can be, but are not limited to, opening adjustment commands sent by the user to the gas stove through the terminal device. For example, the user can select an opening increase command on a third-party application installed on the terminal device, allowing the terminal device to send the opening increase command to the gas stove via Bluetooth (or Wi-Fi), and the control board can receive the opening increase command. This is not a limitation.

[0048] The opening of the damper can be adjusted, but is not limited to, by two positioning plates. For example, taking positioning plate 1 and positioning plate 2 as examples, an opening for air passage is provided in the axial region of the damper. Positioning plate 1 can be set on the surface of the damper and remain fixed, while positioning plate 2 can be set on the surface of the damper (e.g., between positioning plate 1 and the damper) and rotate coaxially with the damper. Here, the opening of the damper can consist of an upper opening and a lower opening arranged symmetrically (i.e., the upper opening and the lower opening have the same shape). Positioning plate 1 can be used to control the airflow through the upper opening, and positioning plate 2 can be used to control the airflow through the lower opening. Preferably, the positioning plates 1 and 2, as well as the upper and lower openings, all have the same shape.

[0049] Understandably, before the damper adjustment device controls the damper to rotate, positioning plate 1 prevents air from passing through the upper opening (meaning positioning plate 1 completely blocks the upper opening), and positioning plate 2 prevents air from passing through the lower opening (meaning positioning plate 2 completely blocks the lower opening). This means the air pipe cannot output air to the burner, and the damper opening is at its minimum. After the damper adjustment device controls the damper to rotate, positioning plate 1 keeps the upper opening blocked from air, while positioning plate 2 moves with the damper... As the rotation controls the airflow through the lower opening, it gradually increases (which can be understood as the area of ​​the lower opening blocked by the positioning plate 2 gradually decreasing). In other words, the air pipe can output air to the gas appliance. At this time, the opening of the damper gradually increases. And it can, but is not limited to, when the positioning plate 2 rotates to coincide with the position of the positioning plate 1, indicating that the airflow through the lower opening is the largest (which can be understood as the positioning plate 2 can no longer block the lower opening, and the positioning plate 2 and the positioning plate 1 simultaneously completely block the upper opening). In other words, the opening of the damper is the largest at this time.

[0050] It should be noted that the air damper, positioning plate 1 and positioning plate 2 mentioned above are all well-known stove components in the field, and will not be described in detail here.

[0051] As an optional embodiment of this application, the damper adjustment device includes a motor and a gear driven by the motor. The motor is electrically connected to a control board, and the damper has gear teeth meshing with the gear on the side near the damper adjustment device; or

[0052] The damper adjustment 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 board, and the damper has gear teeth that mesh with the gear on the side near the damper adjustment device.

[0053] Specifically, the damper adjustment device may include, but is not limited to, a motor and a gear driven by the motor. On the side of the damper near the damper adjustment device, there may be gear teeth that mesh with the gear (the side of the damper away from the damper adjustment device may be a smooth surface, i.e., without gear teeth). The motor receives control signals from the control board (for example, if the motor is a stepper motor, the control signal may be a signal containing a specified number of steps) by connecting to the control board, so as 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. This motor control signal can cause the motor drive gear to rotate in a preset direction by a preset angle, so that when the damper stops rotating, the current opening of the damper can ensure that the airflow passing through is the airflow 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 operation command, so as to cause the motor drive gear to rotate in a specified direction by a specified angle, so that when the damper stops rotating, the current opening of the damper can ensure that the airflow passing through is the airflow that meets the user's adjustment needs.

[0054] In the embodiments of this application, the type of 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 to these.

[0055] It is understood that the damper adjustment 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. On the side of the damper near the damper adjustment device, there are gear teeth that mesh with the gear. The energized coil receives electrical signals from the control board through connection to the control board, so as 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 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 remain stationary in its current position, meaning the gear will not rotate. When the electrical signal received by the energized coil is greater than the preset electrical signal threshold, the magnet can be moved linearly away from the energized coil, causing the gear to rotate clockwise. When the electrical signal received by the energized coil is less than the preset electrical signal threshold, the magnet can be moved linearly closer to the energized coil, causing the gear to rotate counterclockwise, thereby adjusting the damper opening.

[0056] Of course, the electrical signal emitted by the control board can also be the electrical signal emitted by the control board when it first receives the power-on command. This electrical signal can, 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 airflow passing through is the airflow required for normal combustion of the gas stove; or it can be an electrical signal generated according to the user's operation command. This electrical signal can, 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 airflow passing through is the airflow that meets the user's adjustment needs.

[0057] As another optional embodiment of this application, the damper adjustment device further includes a zero-position switch, the circuit of which the zero-position switch is located is connected to the control board; when the damper is at its minimum opening, the contact of the zero-position switch abuts against the outermost tooth on one side of the damper; when the damper is at its maximum opening, the contact of the zero-position switch abuts against the outermost tooth on the other side of the damper.

[0058] Specifically, to ensure the adjustment accuracy of the damper opening, the damper adjustment device may also include a zero-position switch. The circuit containing the zero-position switch is connected to the control board. Before the control board receives the power-on command for the first time, the contact of the zero-position switch can abut against the outermost tooth on one side of the damper. At this time, the zero-position switch is in the open state, that is, the control board cannot detect the high-level signal output by the circuit containing the zero-position switch, and the damper opening is at its minimum. After the control board receives the power-on command for the first time, it can control the damper adjustment device to start rotating the damper, and the contact of the zero-position switch gradually receives the signal. The pressing action of the outermost tooth on one side of the damper causes the zero-position switch to change from an open state to a continuously conducting state. At this time, the control board continuously detects the high-level signal output by the circuit containing the zero-position switch, and the opening of the damper continuously increases from the minimum opening. When the outermost tooth on the other side of the damper abuts against the contact of the zero-position switch, it indicates that the opening of the damper has reached its maximum opening. Therefore, the control board can, but is not limited to, record the airflow rate output from the air pipe to the burner during the process of the damper changing from the minimum to the maximum opening, to obtain the correspondence between the damper opening and the airflow rate. Of course, if the damper adjustment device includes the aforementioned stepper motor and gears driven by the stepper motor, the control board can, but is not limited to, obtaining the correspondence between the damper opening and the number of steps of the stepper motor, and is not limited to this.

[0059] Understandably, after obtaining the correspondence between the damper opening and the airflow, the control panel can, but is not limited to, control the damper adjustment device to automatically adjust the damper opening based on this correspondence, so that the adjusted damper opening can ensure that the airflow passing through is the airflow required for normal combustion of the gas stove, thereby allowing the user to use the gas stove normally, or automatically adjust the damper opening according to the user's adjustment needs.

[0060] See also: Figure 1 The schematic diagram shown is of a damper and damper adjusting device provided in an embodiment of this application. Figure 1 As shown, the damper adjustment device includes a zero-position switch, a motor, and a gear driven by the motor. The damper has gear teeth that mesh with the gear on the side near the damper adjustment device. The surface of the damper is provided with a positioning plate 1 and a positioning plate 2 (the positioning plate 2 is located between the damper and the positioning plate 1, the positioning plate 1 remains fixed, and the positioning plate 2 rotates coaxially with the damper). An opening for air passage is provided in the axial region of the damper. As can be seen, the contact of the zero-position switch abuts against the outermost tooth of one side of the damper, and the positioning plate 1 completely blocks the upper half of the opening, while the positioning plate 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, it drives the damper to rotate clockwise. The positioning plate 2 controls the airflow 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 gasifier. When the outermost tooth of the other side of the damper abuts against the contact of the zero-position switch, the airflow output by the air pipeline is at its maximum.

[0061] It should be noted that the first power-on command mentioned above can be understood as the power-on operation performed by the user on the gas stove after installation (e.g., connecting the gas stove to the power supply for the first time). At this time, the control board can adjust the opening of the damper according to the above embodiment so that the adjusted damper opening can ensure that the airflow is the airflow required for normal combustion of the gas stove. After detecting the user's ignition operation, the control board can output air to the burner according to the adjusted damper opening, thereby enabling the flame to burn.

[0062] Please refer to the following. Figure 2 , Figure 2 This paper presents an overall flowchart of a gas stove intake adjustment method according to an embodiment of the present application.

[0063] like Figure 2 As shown, the gas intake adjustment method for a gas stove may include at least the following steps:

[0064] Step 202: The control board controls the damper adjustment device to adjust the opening of the damper according to the received user operation command, so that the opening of the damper reaches the first opening indicated by the user operation command.

[0065] Specifically, when adjusting the gas intake of the gas stove, 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 user's ignition operation, so that the burner starts to burn flame. Here, the amount of gas output from the gas pipeline to the burner can be determined by the firepower 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 damper opening mentioned in the above embodiment.

[0066] Understandably, in order to ensure that the gas stove is in a normal combustion state when it starts burning, and to effectively avoid the difficulty of disassembling the gas stove to adjust the air damper opening, it is possible, but not limited to, for the control board to control the air damper adjustment device to automatically adjust the current opening of the air damper based on the user operation instructions obtained from the user terminal or control panel, so that the adjusted air damper opening reaches the first opening indicated by the user operation instructions, thereby ensuring that the flame is in a normal combustion state.

[0067] Here, the first opening degree indicated by the user operation command can be determined based on the user operation command and the damper opening degree when the flame starts to burn (which can be, but is not limited to, the default opening degree of the gas stove to ensure that the airflow is the airflow required for normal flame combustion). For example, when the user operation command is to increase the opening degree, the sum of the damper opening degree when the flame starts to burn and the preset opening degree threshold can be used as the first opening degree indicated by the user operation command; or when the user operation command is to decrease the opening degree by one degree, the difference between the damper opening degree when the flame starts to burn and 1 can be used as the first opening degree indicated by the user operation command, and it is not limited to this.

[0068] It is understood that the method by which the control panel controls the damper adjustment device to adjust the damper opening can be referred to the above embodiments, and will not be elaborated here. In addition, the control panel can also adjust the damper opening in real time according to the user operation instructions received in real time, until the flame is in a normal combustion state.

[0069] Please refer to the following. Figure 3 , Figure 3 This paper presents an overall flowchart of another gas stove intake adjustment method provided in an embodiment of this application.

[0070] like Figure 3 As shown, the gas intake adjustment method for a gas stove may include at least the following steps:

[0071] Step 302: Obtain the first gas parameter corresponding to the gas output of the gas pipeline, and control the damper adjustment device to perform a first fine-tuning operation on the damper opening based on the first gas parameter, so that the damper opening is adjusted to the second opening indicated by the first fine-tuning operation.

[0072] During the use of gas stoves, the amount of gas supplied varies at different times of day. For example, the gas supply may be insufficient during peak hours or abundant during off-peak hours, resulting in fluctuations in the amount of gas output to the gas pipeline. Therefore, the airflow from the damper to the burner can be controlled based on the real-time gas supply from the pipeline. This allows for fine-tuning of the damper opening to reduce airflow when gas pressure is insufficient, or fine-tuning to increase airflow when gas supply is abundant. This ensures more complete combustion and prevents flame lift-off.

[0073] Specifically, when adjusting the gas intake of the gas stove, the control board can, but is not limited to, after the air damper opening reaches the first opening indicated by the user's operation command, acquire the first gas parameter corresponding to the gas output from the gas pipeline. This first gas parameter can be a pressure value indicating the gas output from the gas pipeline. For example, it can be acquired by a pressure sensor installed on the gas pipeline, which can be used to acquire the gas pressure output from the valve to the burner (it should be noted that the gas pressure on the gas pipeline also includes the gas pressure output to the gas pipeline, i.e., the gas pressure output from the input end of the gas pipeline to the valve). Of course, the first gas parameter in this embodiment can also be used to indicate the flow rate value of the gas output from the gas pipeline. For example, it can be acquired by a flow sensor installed on the gas pipeline, which can be used to acquire the gas flow rate output from the valve to the burner.

[0074] It is understandable that the first gas parameter mentioned above can also be the flame level used to indicate the output gas from the gas pipeline. This flame level can be obtained by the angle rotated by the user on the flame knob set on the gas stove. For example, after the control board detects the rotation angle of the flame knob, it can determine the flame level corresponding to the rotation angle according to the preset rotation angle-gear correspondence. Alternatively, the flame level can also be obtained by the gear command input by the user on the control panel set on the gas stove. For example, the control board can directly determine the flame level according to the gear command, and it is not limited to this.

[0075] Furthermore, after obtaining the first gas parameters, the control board can, but is not limited to, determine the air flow required for the flame to burn fully at this time based on the first gas parameters, and can control the damper adjustment device to perform a first fine-tuning operation on the current opening of the damper based on the air flow, so that the current opening of the damper is adjusted to the second opening indicated by the first fine-tuning operation, thereby making the flame burn more fully without being affected by the fluctuation of gas pressure in the gas pipeline. Here, the first fine-tuning operation can be understood as either increasing or decreasing the opening degree. For example, the control board can calculate the difference between the airflow required for the flame to burn fully and the airflow corresponding to the first opening degree. When the difference is less than zero, it indicates a decrease in opening degree, and the required decrease in opening degree can be determined based on the difference and the aforementioned correspondence between damper opening degree and airflow. When the difference is greater than zero, it indicates an increase in opening degree, and the increase in opening degree can also be determined based on the difference and the aforementioned correspondence between damper opening degree and airflow. When the difference is equal to zero, it indicates that no first fine-tuning operation is required.

[0076] Based on this, the second opening indicated by the first fine-tuning operation can be the sum of the first opening mentioned above and the required increase in opening, or the difference between the first opening mentioned above and the required decrease in opening.

[0077] It should be noted that the embodiments of this application may also, but are not limited to, directly execute the implementation method mentioned in step 302 above after the burner starts to burn flame, that is, automatically control the damper adjustment device to adjust the opening of the damper without the user's intervention, and are not limited to this.

[0078] As another optional embodiment of this application, the control board controls the damper adjustment device to perform a first fine-tuning operation on the damper opening based on the first gas parameters, so that the damper opening is adjusted to the second opening indicated by the first fine-tuning operation, including:

[0079] The control board determines the fine-tuning opening degree corresponding to the first gas parameter from a preset parameter-opening degree correspondence table; wherein the preset parameter-opening degree correspondence table includes at least two sets of gas parameter ranges, and the standard opening degree corresponding to each set of gas parameter ranges;

[0080] The control damper adjustment device performs a first fine-tuning operation on the damper opening according to the fine-tuning opening degree, so that the damper opening degree is adjusted to the second opening degree indicated by the first fine-tuning operation.

[0081] Specifically, the control panel can look up the standard opening degree (i.e., the second opening degree) corresponding to the first gas parameter in a preset parameter-opening degree correspondence table, and use the absolute value of the difference between the standard opening degree and the aforementioned first opening degree as the fine-tuning opening degree. Here, the preset parameter-opening degree correspondence table includes multiple gas parameter ranges and the standard opening degree corresponding to each gas range. These multiple gas parameter ranges can effectively control the adjustment frequency of the damper adjustment device during fine-tuning operations, so as to realize the automatic fine-tuning of the gas stove by combining the fine-tuning opening degree determined by the first gas parameter.

[0082] See here. Figure 4 The diagram shown is a schematic representation of a preset parameter-aperture correspondence table provided in an embodiment of this application. Figure 4 As shown, when the first gas parameter is the pressure value used to indicate the gas output from the gas pipeline, the preset parameter-opening table can include five gas pressure ranges, and the standard opening corresponding to each gas pressure range (i.e., Figure 4 The damper opening (in the context of gas pressure) can be, for example, but not limited to, when the first gas parameter is in the gas pressure range of [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 embodiments of this application, p1 can be, but is not limited to, 150 Pa, p2 can be, but is not limited to, 450 Pa, p3 can be, but is not limited to, 800 Pa, p4 can be, but is not limited to, 1200 Pa, and p5 can be, but is not limited to, 1500 Pa, and is not limited to these values.

[0083] See also: Figure 5 The diagram shown is a schematic representation of another preset parameter-aperture correspondence table provided in an embodiment of this application, as follows: Figure 5 As shown, when the first gas parameter is used to indicate the flame level when the gas pipeline outputs gas, the preset parameter-opening table can include five flame levels and the standard opening corresponding to each flame level (i.e., Figure 5 The damper opening (in the text) can be, for example, but not limited to, when the first gas parameter is a three-level firepower setting, 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.

[0084] Understandably, when the difference between the standard opening and the aforementioned first opening is less than zero, it indicates that the first fine-tuning operation is a decrease in opening; when the difference between the standard opening and the aforementioned first opening is greater than zero, it indicates that the first fine-tuning operation is an increase in opening. Therefore, the control panel can control the damper adjustment device to perform the first fine-tuning operation on the current opening of the damper, adjusting it to the second opening indicated by the first fine-tuning operation. This ensures that the flame is not affected by fluctuations in the gas pressure in the gas pipeline during combustion, resulting in more complete combustion.

[0085] Please refer to the following. Figure 6 , Figure 6 This paper presents an overall flowchart of another gas stove intake adjustment method provided in an embodiment of this application.

[0086] like Figure 6 As shown, the gas intake adjustment method for a gas stove may include at least the following steps:

[0087] Step 602: Obtain the first gas parameter corresponding to the gas pipeline outputting gas, and obtain the second gas parameter when the gas stove is burning.

[0088] When the flame of a 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 mixture 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). This standard correspondence can be obtained through experimental analysis. When adjusting the gas intake of the gas stove, other gas parameters can be used as feedback signals to compare the difference between the real-time collected values ​​of other gas parameters and the standard values ​​under the ideal combustion state. This allows for a determination of whether to further fine-tune the air damper opening of the gas stove, thereby ensuring more complete combustion, reduced carbon buildup, and higher energy efficiency after the fine-tuning operation.

[0089] Specifically, after the damper is opened to the first opening degree indicated by the user's operation command, the control board can obtain the first gas parameter corresponding to the gas pipeline outputting gas. The method of obtaining the first gas parameter can be referred to the implementation method mentioned in step 302 above, but will not be elaborated here. The second gas parameter when the gas stove is burning can also be obtained. 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 the pressure value used to indicate the gas output from the gas pipeline, the second gas parameter can be the pressure value used to indicate the pressure value of the mixture of gas and air output from the mixing pipeline when the gas stove is burning. One end of the 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 installed between the mixing pipeline and the burner collects and feeds back to the control board, that is, the mixed gas pressure is used as a signal feedback. By comparing the difference between the mixed gas pressure and the corresponding standard value, it is determined whether to further fine-tune the air damper opening of the gas stove, thereby ensuring more complete flame combustion, reducing carbon deposits, and increasing energy efficiency. Of course, in the embodiments of this application, the first gas parameter can also be used to indicate the flow rate value when the gas pipeline outputs gas. In this case, the second gas parameter can be used to indicate the flow rate value of the mixed gas output from the mixing pipeline to the burner, and it is not limited to this.

[0090] It should be noted that when the flame is burning sufficiently, the flame temperature will be relatively high, and the mixed gas pressure output by the pressure sensor will be relatively high. Furthermore, the mixed gas pressure output by the pressure sensor will vary under different gas pressures. When the flame exhibits abnormal phenomena such as excessive redness or flame detachment, the flame temperature will change, and the mixed gas pressure output by the pressure sensor will also change. Therefore, the difference between the mixed gas pressure output at this time and the corresponding standard mixed gas pressure can be used to further fine-tune the damper opening.

[0091] When the first gas parameter is used to indicate the fire level when the gas pipeline outputs gas, the second gas parameter can be used to indicate the thermocouple electromotive force when the gas stove is burning. This thermocouple electromotive force can be collected by the thermocouple detection circuit of the gas stove and output to the control board. In other words, the thermocouple electromotive force is used as a signal feedback. By comparing the difference between the thermocouple electromotive force and the corresponding standard value, it is determined whether to further fine-tune the air damper opening of the gas stove, thereby ensuring more complete combustion of the flame, reducing carbon deposits and increasing energy efficiency.

[0092] It should be noted that when the flame burns sufficiently, the flame temperature is relatively high, resulting in a higher thermocouple electromotive force (EMF) output by the thermocouple detection circuit. Furthermore, the EMF output by the thermocouple detection circuit varies at different flame levels. When the flame exhibits abnormal phenomena such as excessive red-hotness or flame detachment, the flame temperature changes, and the EMF output by the thermocouple detection circuit also changes. Therefore, the difference between the output EMF and the corresponding standard EMF can be used to further fine-tune the damper opening. Here, the thermocouple detection circuit of the gas stove can be a well-known appliance structure in this field, and will not be elaborated upon further.

[0093] When the first gas parameter is used to indicate the firepower level when the gas pipeline outputs gas, the second gas parameter can also be used to indicate the flame temperature of the gas stove during combustion. This flame temperature can be collected by an infrared detector located near the burner of the gas stove and output to the control board. In other words, the flame temperature is used as a signal feedback. By comparing the difference between the flame temperature and the corresponding standard value, it is determined whether to further fine-tune the air damper opening of the gas stove, thereby ensuring more complete combustion, reducing carbon deposits, and increasing energy efficiency.

[0094] It should be noted that the infrared detector utilizes the optical signals radiated by the flame to detect it. When a flame is generated, it emits infrared light of a certain wavelength. The infrared detector captures the infrared light signals from the natural flame and the flame during combustion, and then converts the signals into electrical signals for processing. Here, when the flame is fully combusted, the flame temperature is relatively high, and the flame temperature output by the infrared detector varies at different firepower levels. When the flame exhibits abnormal phenomena such as excessive redness or flame detachment, the flame temperature changes, and the flame temperature output by the infrared detector also changes. Furthermore, by combining the difference between the output flame temperature and the corresponding standard flame temperature, the damper opening can be further fine-tuned. The infrared detector in this embodiment is a detection component well-known in the art, and the relevant control principles will not be elaborated further.

[0095] Step 604: The control panel controls the damper adjustment device to perform a second fine-tuning operation on the damper opening based on the first gas parameters and the second gas parameters, so that the damper opening is adjusted to the third opening indicated by the second fine-tuning operation.

[0096] Specifically, after obtaining the first gas parameter and the second gas parameter, the control board can, but is not limited to, determine the standard parameter corresponding to the first gas parameter from a preset parameter list. The type of the standard parameter can be the same as the type of the second gas parameter. Based on the absolute value of the difference between the standard parameter and the second gas parameter, it can determine whether further fine-tuning of the current opening of the damper is required. When it is determined that fine-tuning of the current opening of the damper is required, the control board controls the damper adjustment device to perform a second fine-tuning operation on the current opening of the damper, so that the opening of the damper is adjusted to the third opening indicated by the second fine-tuning operation, thereby ensuring more complete combustion of the flame, reducing carbon deposits and increasing energy efficiency.

[0097] Here, taking the first gas parameter as the pressure value used to indicate the gas pressure output from the gas pipeline and the second gas parameter as the pressure value used to indicate the pressure value of the gas mixture composed of gas and air output from the gas mixing pipeline when the gas stove is burning as an example, the preset parameter list can be understood as a preset gas-mixed gas correspondence list. This preset gas-mixed gas correspondence list includes multiple gas pressure ranges and the standard mixed gas pressure corresponding to each gas pressure range. The standard parameter here is the standard mixed gas pressure corresponding to the gas pressure range in which the first gas parameter is located.

[0098] Here, taking the first gas parameter as indicating the fire level when the gas pipeline outputs gas and the second gas parameter as indicating the thermocouple electromotive force when the gas stove is burning as an example, the preset parameter list can be understood as a preset gas-electromotive force correspondence list. This preset gas-electromotive force correspondence list includes multiple gas pressure ranges and the standard electromotive force corresponding to each gas pressure range. The standard parameter here is the standard electromotive force corresponding to the gas pressure range in which the first gas parameter is located.

[0099] Here, taking the first gas parameter as indicating the firepower level when the gas pipeline outputs gas and the second gas parameter as indicating the flame temperature of the gas stove during combustion as an example, the preset parameter list can be understood as a preset gas-flame temperature correspondence list. This preset gas-flame temperature correspondence list includes multiple gas pressure ranges and the standard flame temperature corresponding to each gas pressure range. The standard parameter here is the standard flame temperature corresponding to the gas pressure range in which the first gas parameter is located.

[0100] It is understandable that when determining whether further fine-tuning of the current opening of the damper is needed based on the absolute value of the difference between the standard parameters and the second gas parameters, it is possible, but not limited to, when the detected absolute value of the difference is less than or equal to a preset deviation threshold, indicating that the flame combustion is relatively complete, the control panel can control the current opening of the damper to be maintained at the second opening corresponding to the first fine-tuning operation mentioned above (i.e., no adjustment is made). Of course, in the embodiments of this application, if the current opening of the damper is the first opening indicated by the user operation command mentioned above, the control panel can also control the opening of the damper to be maintained at the first opening indicated by the user operation command, and it is not limited to this.

[0101] It should be noted that the preset deviation threshold mentioned here 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 can 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 can 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 can be a preset flame temperature deviation threshold.

[0102] When the absolute value of the difference is detected to be greater than the preset deviation threshold, it indicates that the flame is not in a state of complete combustion. Therefore, when the difference between the standard parameter and the second gas parameter is detected to be less than zero, the second fine-tuning operation is determined to be a reduction in opening. The required reduction in opening can be, but is not limited to, the preset fine-tuning opening threshold. The control board can then control the damper adjustment device to fine-tune the current opening of the damper according to this second fine-tuning operation and the preset fine-tuning opening threshold, so that the damper opening is fine-tuned to the third opening indicated by the second fine-tuning operation. This third opening is the current opening of the damper (which can be either the first or second opening mentioned above). The difference between the standard parameter and the second gas parameter is calculated. When the difference between the standard parameter and the second gas parameter is greater than zero, the second fine-tuning operation is determined to be an operation to increase the opening. The required increase in opening can be, but is not limited to, the preset fine-tuning opening threshold. The control board can control the damper adjustment device to fine-tune the current opening of the damper according to the second fine-tuning operation and the preset fine-tuning opening threshold, so that the opening of the damper is fine-tuned to the third opening indicated by the second fine-tuning operation. The third opening is the sum of the current opening of the damper (which can be the first opening or the second opening mentioned above) and the preset fine-tuning opening threshold.

[0103] For example, but not limited to taking gas pressure as the type of the second gas parameter, 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 by decreasing; if the standard mixed gas pressure is greater than the mixed gas pressure, the damper opening is fine-tuned by increasing.

[0104] Alternatively, 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 less than the thermocouple electromotive force, the damper opening is fine-tuned by decreasing it; if the standard electromotive force is greater than the thermocouple electromotive force, the damper opening is fine-tuned by increasing it.

[0105] Alternatively, taking flame temperature as an example of the second gas parameter, 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 by decreasing; if the standard flame temperature is greater than the obtained flame temperature, the damper opening is fine-tuned by increasing.

[0106] Of course, the preset fine-tuning opening threshold in the embodiments of this application can also be determined according to the preset deviation threshold. For example, but not limited to, when the preset deviation threshold is in a certain deviation range, the opening threshold corresponding to the deviation range can be used as the preset fine-tuning opening threshold, and it is not limited to this.
