[0002] With the rapid development of society, residents have higher and higher requirements for the quality of life. However, the level of intelligence of common gas stoves is still relatively low. They all require professional personnel to come to the site for installation and adjust the air damper to ensure that the combustion conditions are fixed. Significant changes in the usage environment or accidental touches by the user will change the combustion conditions and cause various problems. At this time, professional personnel are needed to come to the site for adjustment, which consumes manpower and resources.

[0003] In existing technology, the damper cover is driven by a motor to move relative to the air inlet to change the opening of the air inlet. The motor is controlled by a controller to realize the electric function of damper adjustment. However, the level of intelligence is not high, and manual control and adjustment of the damper are still required. It cannot achieve full automation, nor can it determine whether the combustion conditions are in the optimal state. Summary of the Invention

[0020] The power component includes a receiving cavity, which contains:

[0021] The first driving component has a transmission wheel on it, and the transmission wheel engages with the first screw structure that extends into the receiving cavity;

[0022] The second driving member is disposed opposite to the first driving member, and a transmission wheel is disposed thereon, which engages with the second screw structure that extends into the receiving cavity.

[0023] The receiving cavity is integrally formed with the first limiting structure and the second limiting structure.

[0024] The support structure includes an annular ring and several supporting structures evenly arranged along the circumference of the annular ring. The annular ring is located on the outside of the burner, and the supporting structures protrude upward from the annular ring in the height direction. The gas detection device is located on the supporting structures.

[0025] The gas detection device is a carbon monoxide detection device, suitable for detecting the concentration of carbon monoxide in flue gas.

[0026] A gas stove control method, the gas stove including an air damper structure and an ejector tube structure, includes the following steps: obtaining the volume fraction of carbon monoxide; determining whether the volume fraction of carbon monoxide falls within a preset range; and controlling the air damper structure to move closer to or further away from the ejector tube structure based on whether it falls within the preset range.

[0028] The gas stove control method provided by the present invention controls the damper adjustment device to move away from the damper structure when the volume fraction of carbon monoxide is greater than the upper end of the preset range.

[0029] The gas stove control method provided by the present invention includes an air damper structure comprising an inner ring air damper plate and an outer ring air damper plate, and an ejector tube structure comprising a first ejector tube corresponding to the inner ring air damper plate and a second ejector tube corresponding to the outer ring air damper plate.

[0032] The technical solution of this invention has the following advantages:

[0033] 1. The present invention provides a gas stove, comprising a panel and a bottom shell, wherein a burner and a support structure arranged circumferentially along the burner are disposed on the panel, and further comprising: an air damper adjustment device disposed inside the bottom shell, adapted to adjust the airflow of the air damper structure connected to the burner; a gas detection device disposed on the panel, adapted to detect the gas composition in the flue gas emitted by the burner in the working state; and a controller disposed inside the bottom shell, which is communicatively connected to the air damper adjustment device and the gas detection device respectively.

[0034] The gas composition in the flue gas is detected by a gas detection device. After the signal is transmitted to the controller, it is compared and identified to determine whether the air supply of the burner is sufficient in the working environment. The controller then controls the airflow of the damper adjustment device according to the situation to ensure the normal operation of the burner. This setting enables the damper structure to automatically adjust the damper, making it more intelligent. At the same time, it makes combustion more complete, the combustion conditions more stable and efficient, and reduces the emission of harmful gases. It also eliminates the need for professional personnel to install and adjust it, saving manpower and making it more convenient for users.

[0035] 2. The gas stove provided by the present invention includes an air damper adjustment device comprising: a guide member movably connected to an air damper plate structure on the air damper structure; and a power member communicatively connected to the controller, wherein the air damper plate structure is adapted to move along the guide member under the action of the power member.

[0038] This configuration allows for the adjustment of the travel stroke of different damper plates, thereby controlling the gap between each damper plate and the end opening of the ejector tube.

[0053] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0054] Example 1

[0055] like Figure 1 - Figure 5 This embodiment provides a gas stove, including a panel 1 and a bottom shell 2. The panel 1 is provided with two burners 7 and a switch knob, as well as a support structure 8 for supporting cookware arranged around the burners 7. The bottom shell 2 is also provided with an air damper structure 5, which includes an injector tube. One end of the injector tube is connected to the burner 7, and the other end is provided with a flanged annular port, at which a damper plate structure is correspondingly provided. In addition, the gas stove also includes an air damper adjustment device 3, a gas detection device 4, and a controller 6.

[0056] The damper adjustment device 3 is located inside the bottom shell 2, adjacent to the burner 7, and is movably connected to the damper structure 5, which can adjust the airflow of the damper structure 5.

[0057] The gas detection device 4 is installed on the panel 1 and can detect the gas composition in the flue gas emitted by the burner 7 when it is working. In this embodiment, the gas detection device 4 is installed on the support structure 8. The support structure 8 includes a square-shaped annular ring and four supporting structures evenly arranged along the circumference of the annular ring. The annular ring is located on the outside of the burner 7. The supporting structures protrude upward from the annular ring in the height direction and the protrusion height is higher than that of the burner 7. The gas detection device 4 is distributed on each supporting structure, which facilitates multi-directional detection of flue gas and improves the accuracy of detection.

[0058] The controller 6 is located inside the bottom shell 2 and is electrically connected to the damper adjustment device 3 and the gas detection device 4, respectively. In this embodiment, the controller 6 is a microcontroller.

[0059] The gas composition in the flue gas is detected by the gas detection device 4. After the signal is transmitted to the controller 6, it is compared and identified to determine whether the air supply of the burner 7 is sufficient in the working environment. The controller then controls the airflow of the damper adjustment device 3 according to the situation to ensure the normal operation of the burner 7. This setting enables the damper structure 5 to automatically adjust the damper, making it more intelligent. At the same time, it makes the combustion more complete, the combustion conditions more stable and efficient, and reduces the emission of harmful gases. It also eliminates the need for professional personnel to install and adjust it, saving manpower and making it more convenient for users.

[0060] The damper adjustment device 3 includes a guide member and a power member. The guide member is movably connected to the damper plate structure on the damper structure 5; the power member is electrically connected to the controller 6, and the damper plate structure can move along the guide member under the action of the power member. This configuration achieves control of the air intake volume of the damper structure 5 by controlling the movement of the damper plate, and the structure is simple and easy to implement. In this embodiment, the guide member is a screw structure and the power member is a motor. As a possible alternative implementation, the guide member can be an electric actuator, an electric cylinder, or a pneumatic cylinder.

[0061] The damper structure 5 includes two damper plate structures and two ejector tubes. The damper plate structures include an inner ring damper plate 52 and an outer ring damper plate 54. The ejector tubes are divided into a first ejector tube 51 and a second ejector tube 53. The first ejector tube 51 is connected to the inner ring of the burner 7 and the inner ring damper plate 52, respectively, and the second ejector tube 53 is connected to the outer ring of the burner 7 and the outer ring damper plate 54. This arrangement allows for the adjustment of the movement stroke of different damper plates, thereby controlling the gap between each damper plate and the end opening of the ejector tube. This enables separate control of the airflow at multiple positions of the burner 7, achieving multi-stage control of the airflow and improving adjustment efficiency.

[0062] As a variable implementation method, the number of damper structures and ejector tubes can be one or more sets.

[0063] The guide includes two screw structures and two limiting structures.

[0064] The first screw structure 31 engages with the first receiving hole 521 on the bottom side of the inner ring damper plate 52, and the inner side of the first receiving hole 521 is provided with an internal thread that engages with the first screw structure 31; the second screw structure 32 engages with the second receiving hole on the bottom side of the outer ring damper plate 54, and the inner side of the second receiving hole is provided with an internal thread that engages with the second screw structure 32.

[0065] The first limiting structure 33 is provided on the bottom side of the first screw structure 31, and a limiting groove 39 is provided along the extension direction of the first screw structure 31. The limiting groove 39 is engaged with the limiting flange 55 on the inner ring damper plate 52. The second limiting structure 34 is provided on the bottom side of the second screw structure 32, and a limiting groove 39 is provided along the extension direction of the second screw structure 32. The limiting groove 39 is engaged with the limiting flange 55 on the outer ring damper plate 54.

[0066] In this embodiment, the limiting grooves 39 on the first limiting structure 33 and the second limiting structure 34 are arranged in the same shape, and the limiting flanges 55 on each damper plate are arranged in the same shape. Each limiting structure includes two extension plates parallel to the screw structure. The extension plates have a limiting groove 39 or a limiting elongated hole in the middle of the height direction. Each receiving hole on the damper plate has an extension portion on its lower side. The extension portion extends into the space between the two extension plates. The extension portion has two limiting flanges 55 perpendicular to the moving direction of the damper plate. The limiting flanges 55 extend into the limiting grooves 39 to achieve supplementary limiting of the movement of the damper plate.

[0067] The damper plate is provided with a limiting flange 55, which can cooperate with the limiting groove 39 on each limiting structure to ensure that the screw structure and the internal thread structure on the damper plate can maintain a meshing state. By limiting the circumferential displacement of the damper plate along the movement direction, the damper plate can move stably along the screw structure, thereby improving the movement stability of the damper plate during the adjustment of the damper ventilation volume.

[0068] In this embodiment, the first screw structure 31 and the second screw structure 32, as well as the first limiting structure 33 and the second limiting structure 34, are arranged in parallel. This arrangement is simple and easy to manufacture and assemble. As an alternative implementation, the first screw structure 31 and the second screw structure 32, as well as the first limiting structure 33 and the second limiting structure 34, can also be arranged in a non-parallel manner.

[0069] The power component includes a receiving cavity 35, which houses a first drive component 36 and a second drive component 37 that are respectively connected to the controller 6. In this embodiment, the first drive component 36 and the second drive component 37 are stepper motors.

[0070] The first driving member 36 is provided with a transmission wheel 38, which engages with the first screw structure 31 extending into the receiving cavity 35; the second driving member 37 is disposed opposite to the first driving member 36, and is provided with a transmission wheel 38, which engages with the second screw structure 32 extending into the receiving cavity 35.

[0071] In this embodiment, the receiving cavity 35 is integrally formed with the first limiting structure 33 and the second limiting structure 34. As an alternative implementation, the receiving cavity 35 may be omitted, and the first driving member 36 and the second driving member 37 may be separated.

[0072] In this embodiment, the gas detection device 4 is a carbon monoxide detection device, which is suitable for detecting the concentration of carbon monoxide in flue gas.

[0073] Example 2

[0074] This embodiment provides a gas stove control method, such as... Figure 6 As shown, the gas stove includes an air damper structure 5 and an injector structure, and includes the following steps:

[0075] S1. Obtain the volume fraction of carbon monoxide;

[0076] In this embodiment, the volume fraction of carbon monoxide indicates the ratio between the volume of carbon monoxide (Vco) entering the gas stove and the total gas volume (Vgas) entering the gas stove. Vgas includes not only the volume of carbon monoxide but also oxygen, nitrogen, and other trace gases in the air. Specifically, the volume fraction of carbon monoxide is defined as Vco / Vgas.

[0077] S2. Determine whether the volume fraction of carbon monoxide falls within the preset range;

[0078] In this embodiment, the set interval value is [0.02-0.03].

[0079] S3. Depending on whether it falls within a preset range, control the damper structure 5 to move closer to or further away from the ejector tube structure.

[0080] S31. When the volume fraction of carbon monoxide is less than the lower end of the preset range, control the damper structure 5 to move closer to the ejector structure.

[0081] This step also includes: determining the difference between the lower end of the preset interval and the volume fraction of carbon monoxide; when the difference is greater than a third preset value, controlling the inner ring damper 52 to move closer to the first ejector tube; when the difference is greater than a fourth preset value, controlling the outer ring damper 54 to move closer to the second ejector tube 53; wherein the third preset value is less than the fourth preset value.

[0082] S32. When the volume fraction of carbon monoxide is greater than the upper end of the preset range, control the damper adjustment device 3 to move away from the damper structure 5.

[0083] In this step, the difference between the volume fraction of carbon monoxide and the upper end of the preset range is determined; when the difference is greater than a first preset value, the inner ring damper 52 is controlled to move away from the first ejector tube; when the difference is greater than a second preset value, the outer ring damper 54 is controlled to move closer to the second ejector tube 53; wherein, the second preset value is greater than the first preset value.

[0084] In this embodiment, the range of the first preset value is (0.01-0.02), at which time the volume fraction of carbon monoxide is (0.04-0.05); the second preset value is 0.05, at which time the volume fraction of carbon monoxide is 0.08.

[0085] The third preset value is 0.01, at which point the volume fraction of carbon monoxide is 0.01; the fourth preset value is 0.015, at which point the volume fraction of carbon monoxide is 0.005.

[0086] It should be noted that the order of steps S31 and S32 can be interchanged.

[0087] In this embodiment, the damper structure 5 includes an inner ring damper plate 52 and an outer ring damper plate 54, and the ejector tube structure includes a first ejector tube 51 corresponding to the inner ring damper plate 52 and a second ejector tube 53 corresponding to the outer ring damper plate 54. Furthermore, to achieve the adjustment action between the damper adjustment device and the damper structure 5, a first screw structure 31 and a second screw structure 32 are respectively provided on the inner ring damper plate 52 and the outer ring damper plate 54.

[0088] Work process:

[0089] When the user starts cooking, the gas detection device 4 starts to collect and analyze the volume fraction of carbon monoxide concentration in the flue gas and feeds this concentration value back to the controller 6. After receiving the information, the controller 6 compares it with the preset range value. When the actual CO concentration volume fraction is within the range, it indicates that the combustion condition is good. At this time, the damper structure does not move.

[0090] When the volume fraction of carbon monoxide is greater than the highest value of the set interval, that is, greater than the upper endpoint value of the interval in this embodiment (0.03), the next comparison is performed. If the volume fraction of carbon monoxide is much greater than 0.03, such as when the actual CO concentration is 0.08, the controller 6 sends a signal to the damper adjustment mechanism, which rotates the second drive component 37 to control the outer ring damper 54 to move backward, thus opening the outer ring damper. If the volume fraction of carbon monoxide is only slightly greater than 0.03, for example, when the actual value is between 0.03 and 0.05, the controller 6 sends a signal to the damper adjustment device 3, which rotates the first drive component 36 to control the inner ring damper 52 to move backward, thus opening the inner ring damper.

[0091] When the volume fraction of carbon monoxide is less than the lowest value of the preset range, that is, less than the lower end value of the preset range of 0.02 in this embodiment, the next comparison is performed. If the volume fraction of carbon monoxide is much less than 0.02, for example, the actual value reaches 0.01 or below, the controller 6 sends a signal to the damper adjustment device 3 to rotate the second drive component 37 to control the movement of the outer ring damper plate 54 and close the outer ring damper. If the volume fraction of carbon monoxide is not much less than 0.02, for example, the actual value is 0.005, the controller 6 sends a signal to the damper adjustment device 3 to rotate the motor to control the movement of the inner ring damper plate 52 and close the inner ring damper. This cycle continues until the volume fraction of carbon monoxide is within the preset optimal range.

[0092] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
