[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Currently, the burners of common cookers on the market generally use copper alloy or aluminum alloy as raw materials. Although these two materials have excellent performance in terms of durability and heat conductivity, their costs are relatively high. At the same time, a large amount of energy is consumed during the production and manufacturing process, which is not conducive to energy conservation, emission reduction and cost control.

[0036] In some existing technologies, stainless steel thin plates are used as alternative materials to provide a double-ring inner-flame type burner. However, since the burner is made of a sheet metal structure, the overall assembly error is relatively large, which to a certain extent affects the combustion performance of the burner, resulting in problems such as uneven combustion and low thermal efficiency.

[0037] Please refer to Figures 1 to 6 , to solve the above technical problems, the present application proposes an air door fixing seat 100, a burner assembly 1000 and a cooker. Among them, the air door fixing seat 100 includes a main board 1 and at least two mounting sleeves 2. At least two mounting sleeves 2 are connected to the same side of the main board 1. Each mounting sleeve 2 forms a mounting channel 23. At least a part of an ejector tube 200 is installed in the mounting channel 23 of each mounting sleeve 2. The main board 1 is provided with a gas inlet 24 and an air inlet 25 that communicate with each mounting channel 23.

[0038] In the embodiment of the present application, the main board 1 is used to connect and carry at least two mounting sleeves 2. Each mounting sleeve 2 is located on the same side of the main board 1 and is used for alignment installation with each ejector tube 200. Each mounting sleeve 2 correspondingly forms a mounting channel 23, which is convenient for the ejector tube 200 to extend into the mounting channel 23 for plug-in installation. The mounting channel 23 can not only simplify the disassembly and assembly process of the ejector tube 200, but also ensure that the ejector tube 200 can be accurately aligned with the gas inlet 24 and the air inlet 25 on the main board 1, thereby ensuring the centering of the ejector tube 200 with the gas inlet 24 and the air inlet 25.

[0039] It can be understood that a gas inlet 24 and an air inlet 25 communicating with each installation channel 23 are provided on the main board 1. Among them, gas enters the ejector tube 200 through the gas inlet 24, and air enters the ejector tube 200 through the air inlet 25. The combustible gas mixture of the two is ignited to generate a flame. The gas inlet 24 can facilitate the centering installation with the components of the gas nozzle, thereby ensuring the smoothness and safety of gas transportation and improving the combustion efficiency.

[0040] At least two mounting sleeves 2 are located on the main board 1 and have a certain extension length, which can play a certain guiding installation role, have a better wrapping effect on the ejector tube 200, and facilitate the alignment installation of the ejector tube 200.

[0041] Please refer to Figure 1 and Figure 2 , an ejector tube installation position 26 is provided on the side wall of each mounting sleeve 2. At least two mounting sleeves 2 are distributed along the first direction X, and the ejector tube installation positions 26 on at least two mounting sleeves 2 are respectively located on the opposite sides of one of the mounting sleeves 2 along the second direction Y, and the first direction X intersects with the second direction Y. In order to ensure the firmness of the assembly of the ejector tube 200 and the mounting sleeve 2, an ejector tube installation position 26 is also provided on the side wall of each mounting sleeve 2. Among them, the ejector tube installation position 26 is used for fitting installation with the ejector tube 200 to fix the ejector tube 200 into the installation channel 23 to prevent the ejector tube 200 from loosening or shaking. Specifically, the ejector tube installation position 26 includes a mounting hole, and the ejector tube 200 can be fixed in cooperation by passing a mounting screw through the mounting hole, so as to achieve the fixing effect of the ejector tube 200 and enhance the connection strength between the ejector tube 200 and the mounting sleeve 2. In some embodiments, the ejector tube installation position 26 also includes mounting hooks, limit bumps, etc., and the present application does not limit this here, as long as it can play the role of installing and stabilizing the ejector tube 200.

[0042] Furthermore, regarding the specific position of the ejector tube installation position 26 on the mounting sleeve 2, there are at least two mounting sleeves 2 in the present application. The ejector tube installation positions 26 at the two mounting sleeves 2 are located on the opposite sides along the second direction Y at each ejector tube 200. It can be understood that, in some embodiments, refer to Figure 1, the first direction X is the horizontal direction, the second direction Y is the vertical direction. One injection pipe installation position 26 is located at the top of an installation sleeve 2, and the other injection pipe installation position 26 is located at the bottom of another installation sleeve 2. The two injection pipe installation positions 26 are arranged oppositely in the position along the second direction Y, realizing diagonal fixation, so that the stress received by the locking between the injection pipe installation position 26 and the injection pipe 200 is more uniform, and it can prevent loosening on one side, ensuring the stability of the installation of the injection pipe 200. In some other embodiments, the injection pipe installation positions 26 at the two installation sleeves 2 can also be located on the same side. The injection pipe installation positions 26 located on the same side are convenient for installation and disassembly, and can simplify the assembly process. This application does not make a limitation here.

[0043] In some embodiments, at least two installation sleeves 2 include a first installation sleeve 21 and a second installation sleeve 22. The first installation sleeve 21 is located above the second installation sleeve 22. A notch 21a is provided at the top of the first installation sleeve 21. The gas inlet 24 and the air inlet 25 of the first installation sleeve 21 are both separated from the notch 21a. Specifically, the first installation sleeve 21 and the second installation sleeve 22 are respectively installed and cooperated with two injection pipes 200. The main board 1 has a top end and a bottom end arranged oppositely. Among them, the first installation sleeve 21 is arranged near the top end, and the second installation sleeve 22 is arranged near the bottom end. The first installation sleeve 21 is higher than the second installation sleeve 22. In the actual assembly process, since the first installation sleeve 21 is located at the top end of the main board 1 and has a notch 21a at its top, due to the overall assembly dimension requirements of the air door fixing seat 100, the notch 21a at the top can be used to avoid the components assembled nearby, such as the glass panel, etc., providing installation space for other components. And, in order to ensure that the air-gas mixing ratio can be controlled within a certain range, the notch 21a is separated from the gas inlet 24 and the air inlet 25, which can control the air to only enter the injection pipe 200 at the air inlet 25, prevent the air from leaking from the notch 21a, and will not change the air flow rate. Similarly, the gas can only enter the injection pipe 200 from the gas inlet 24, which can effectively prevent the gas from leaking from the notch 21a and ensure that the ratio between the gas and the air is within a reasonable range.

[0044] Please refer to Figure 3 , the air door fixing seat 100 further includes at least two air door adjusting members 3. Each air door adjusting member 3 corresponds to an air inlet 25. Each air door adjusting member 3 can move relative to the main board 1 to adjust the opening degree of the corresponding air inlet 25. In the embodiment of the present application, the air door adjusting member 3 is correspondingly arranged at the air inlet 25. The air door adjusting member 3 can move relative to the main board 1. By covering and exposing the air inlet 25, the actual air inlet area of the air inlet 25 is changed, and then the actual air flow rate of the air inlet 25 is changed, so as to achieve the effect of adjusting the air-gas ratio and realize the adjustment of the flame size.

[0045] Furthermore, please refer toFigures 4 to 5 The damper adjustment member 3 includes a damper adjustment piece 31 and a paddle 32. The damper adjustment piece 31 is arranged corresponding to the air inlet 25. The paddle 32 is connected to the damper adjustment piece 31 and protrudes from the main board 1. The paddle 32 can move relative to the main board 1, thereby driving the damper adjustment piece 31 to move to adjust the opening and closing degree of the air inlet 25. Specifically, when the paddle 32 is controlled manually or mechanically to drive the damper adjustment piece 31 to move, the movement of the damper adjustment piece 31 changes the opening and closing degree of the air inlet 25, thereby adjusting the air intake volume and realizing the adjustment of the flame size. Such a setting can flexibly control the opening and closing degree of the air inlet 25, thereby meeting different air flow requirements, and has a simple structure and good operability.

[0046] Please continue to refer to Figures 4 to 5 The main board 1 is provided with two limiting protrusions 11 corresponding to each mounting channel 23. The two limiting protrusions 11 are arranged at intervals along the movement path of the damper adjusting member 3 so that the damper adjusting member 3 moves between the two limiting protrusions 11. It can be understood that in order to facilitate the control of the damper adjusting member 3, the damper adjusting member 3 is located on the side of the main board 1 away from the mounting sleeve 2. Therefore, the two limiting protrusions 11 are also arranged at the side of the main board 1 away from the mounting sleeve 2. In the embodiment of the present application, the two limiting protrusions 11 are arranged at intervals at the movement path of the damper adjusting member 3 to block the movement of the damper adjusting member 3, thereby limiting the range in which the damper adjusting member 3 can move, so that the damper adjusting member 3 moves on a predetermined path. Such an arrangement ensures the accuracy of the movement path of the damper adjusting member 3, makes the opening adjustment of the air inlet 25 more accurate, and improves the combustion efficiency. In addition, the limiting protrusions 11 can support the damper adjusting member 3 to a certain extent, prevent it from shaking or deflecting during the movement, and enhance the structural stability.

[0047] For further information, please refer to Figures 4 to 5 , the main board 1 is provided with at least two gear protrusions 12 corresponding to each installation channel 23, at least two gear protrusions 12 are arranged at intervals along the movement path of the damper adjustment member 3 and are both located between the two limiting protrusions 11, the height of the gear protrusion 12 protruding from the main board 1 is less than the height of the limiting protrusion 11 protruding from the main board 1, and the damper adjustment member 3 can pass over the gear protrusion 12. In order to achieve the adjustment of the gear position, at least two gear protrusions 12 are provided in the embodiment of the present application to achieve high, medium and low gear combustion firepower. In the embodiment of the present application, the gear protrusion 12, the limiting protrusion 11 and the damper adjustment member 3 are all located on the side of the main board 1 away from the installation sleeve 2, and a plurality of gear protrusions 12 are arranged at intervals between the two limiting protrusions 11, so that the damper adjustment member 3 can achieve the gear adjustment function within the range limited by the limiting protrusion 11.

[0048] Specifically, the air damper adjusting member 3 is blocked by the limiting protrusion 11 and cannot cross the limiting protrusion 11, and it moves within a certain range. Since the height of the gear protrusion 12 is less than the height of the limiting protrusion 11, although the air damper adjusting member 3 will be limited to a certain extent by the gear protrusion 12, it can cross the gear protrusion 12 and move. On the one hand, the air damper adjusting member 3 can be blocked between the gear protrusions 12 and between the gear protrusion 12 and the limiting protrusion 11, so that the air damper adjusting member 3 is maintained in a certain gear position, ensuring a certain ratio of the intake air volume and the gas. On the other hand, when driven by an external force, the air damper adjusting member 3 can move away from the current gear position, that is, cross the gear protrusion 12 and move to the gap between the current gear protrusion 12 and the adjacent gear protrusion 12. When the external force stops driving, it is limited in the current gear position, realizing the gear shift and further realizing the function of gear adjustment.

[0049] In the embodiment of the present application, the air damper adjusting member 3 can rotate relative to the main board 1 to adjust the opening degree of the corresponding air inlet 25. In some of the above embodiments, the air damper adjusting member 3 includes an air damper adjusting piece 31 and a dial 32. The air damper adjusting piece 31 rotates with the rotation of the dial 32. An avoidance portion and a shielding portion are correspondingly arranged on the air damper adjusting piece 31. During the rotation of the air damper adjusting member 3, the avoidance portion can increase the exposed area of the ventilation opening and increase the air flow rate, while the shielding portion covers the ventilation opening and reduces the exposed area of the ventilation opening, thereby reducing the air flow rate and adjusting the opening degree of the corresponding air inlet 25, facilitating the realization of the function of gear adjustment.

[0050] In some of the previous embodiments, since the top of the first mounting sleeve 21 has a notch 21a, the structures of the air damper adjusting member 3 corresponding to the first mounting sleeve 21 and the second mounting sleeve 22 are also different. Corresponding to the first mounting sleeve 21, the outer contour line of the air damper adjusting piece 31 includes a first outer contour line and a second outer contour line. The first outer contour line is closer to the center of the air damper adjusting piece 31 than the second outer contour line. Among them, the first outer contour line can be closer to the notch 21a than the second outer contour line, ensuring that the air damper adjusting piece 31 does not interfere with other components installed corresponding to it; among them, at least part of the air inlet 25 is located between the first outer contour line and the second outer contour line along the radial direction of the air damper adjusting piece 31, so that by rotating the air damper adjusting piece 31, the shielding degree of the part of the air inlet 25 located between the first outer contour line and the second outer contour line in the radial direction by the air damper adjusting piece 31 can be changed. For the second mounting sleeve 22, the outer contour line of the air damper adjusting piece 31 is generally circular, and the air damper adjusting piece 31 is generally provided with ventilation holes in the circular plate. By rotating the air damper adjusting piece 31, the ventilation holes are made to correspond to the air inlet 25, the air flow rate can be increased, and by rotating the air damper adjusting piece 31 again, the ventilation holes and the air inlet 25 are gradually staggered, and the air flow rate can be reduced. With such a setting, the air damper adjusting member 3 can realize the function of corresponding gear adjustment, and has a simple structure, and can adapt to different mounting sleeves 2 and cooperate with other components. It can be understood that the air damper adjusting piece 31 also avoids the gas inlet 24, and this is not limited herein.

[0051] Furthermore, the air inlet 25 extends along the circumferential direction of the gas inlet 24, and the air damper adjusting member 3 can rotate relative to the central axis of the gas inlet 24 to adjust the opening and closing degree of the corresponding air inlet 25. In the embodiments of the present application, the air inlet 25 is located on the circumferential side of the gas inlet 24, and the air inlet 25 is an arc-shaped area extending along an arc around the gas inlet 24. The air damper adjusting member 3 is correspondingly provided with a gas hole for exposing the gas inlet 24, facilitating the assembly of the gas inlet 24 and the gas nozzle. The air damper adjusting member 3 can rotate relative to the axis of the gas inlet 24 to change the opening and closing degree of the corresponding air inlet 25, thereby controlling the air intake volume, ensuring that the ratio of gas to air is within a certain range, and ensuring sufficient combustion.

[0052] In addition, in some other embodiments, the air inlet 25 includes at least two sub-air inlets 25a arranged at intervals along the circumferential direction of the gas inlet 24. The above-mentioned sub-air inlets 25a can control the amount of intake air alone or together with other sub-air inlets 25a. With such a setting, it has better safety. In the case where one of the sub-air inlets 25a is damaged or blocked, the other sub-air inlets 25a can work normally to ensure the normal delivery of air.

[0053] Please refer to Figure 1, the damper fixing base 100 further includes a bottom plate 4. The bottom plate 4 is located below the main board 1 and is connected to the main board 1. The bottom plate 4 is disposed at an angle relative to the main board 1, and a fixing position 41 is provided on the bottom plate 4. To enhance the limiting effect of the damper fixing base 100, the fixing position 41 on the bottom plate 4 is used to fix the damper fixing base 100 on the installation surface to ensure its stability and safety. Specifically, there are two fixing positions 41 on the bottom plate 4, which are oppositely arranged along the extending direction of the bottom plate 4, so as to achieve a better fixing and installation effect of the bottom plate 4 through the two fixing positions 41, further ensuring the stability of the damper fixing base 100, and also ensuring the stable support and limiting effect of the injection pipe 200 connected to the installation sleeve 2.

[0054] The fixing position 41 at the bottom plate 4 includes a fixing hole, and can be connected and fixed to the installation surface by means of threaded connection. In some other embodiments, the fixing position 41 can be a snap connection structure, a convex block mating connection structure, etc., as long as it can achieve the effect of fixed installation, and the present application does not make any restrictions here.

[0055] In addition, in the present application, the main board 1, at least two installation sleeves 2, and the bottom plate 4 are integrally formed aluminum alloy parts, which can ensure that the relative installation dimensions between at least two installation sleeves 2, that is, between two injection pipes 200, are certain, and can also ensure that the assembly dimensions between the bottom plate 4 and the installation surface are certain, so as to achieve a more precise fixing effect, reduce the errors in dimensions and distances caused by the installation of each component, and achieve a better limiting and centering effect.

[0056] In a second aspect, please refer to Figure 6 , an embodiment of the present application provides a burner assembly 1000. The burner assembly 1000 includes the above-mentioned damper fixing base 100; at least two injection pipes 200; and at least two burner bodies 300, and each burner body 300 is communicated with each injection pipe 200. Among them, the two burner bodies 300 include an inner burner body and an outer burner body, and the inner burner body and the outer burner body are respectively communicated with each injection pipe 200, so as to achieve a further fixing effect on the inner burner body and the outer burner body.

[0057] In an embodiment of the present application, the burner assembly 1000 further includes a burner bracket and a bottom shell.

Among them, the outer burner body and the inner burner body are respectively fixedly connected to the bracket to achieve the positioning and supporting effects of the burner body 300. At the same time, a fixing position is correspondingly provided on the side of the bracket close to the bottom shell for connecting and fixing the bracket and the bottom shell, thereby improving the overall stability of the burner assembly 1000 and further enhancing the supporting effect of the bracket.

[0058] In addition, the burner assembly 1000 can be fixed to the bottom shell through the fixing position 41 on the air door fixing seat 100 and the fixing positions on the burner bracket, achieving the multi-point positioning and fixing effects at the air door fixing seat 100 and the bracket, which helps to improve the overall strength of the burner assembly 1000 and prevent the burner assembly 1000 from shaking and affecting the overall performance of the product.
