Description

Technical Field

[0001] This invention relates to the field of cooktop technology, and in particular to a gas duct adjustment mounting plate, a burner, and a cooktop. Background Technology

[0002] like Figure 1 As shown, the structure of the nozzle mounting plate 01 of the existing top-intake stove is to set a flat surface below the burner, extend the pipe to the required place, drill through the gas passage by means of a rotating hole, and then install sealing steel balls at the rotating hole. Alternatively, a simpler method is to lead a single pipe directly to the bottom of the nozzle. The principle of the existing mounting plate is to lead two pipes from the valve body to the vicinity of the nozzle to form a double gas passage with a central outer ring.

[0003] The drawback of the existing structure is that if the air passage is directly introduced from the valve body to below the nozzle, the number of nozzles corresponds to the number of valve core layers in the valve body. This means that a conventional double-ring valve body leads to two air passages forming two single-ring flames. Single-ring gas outlets at a single point lead to uneven gas mixing and combustion, necessitating a reduction in load. Using a mounting plate structure results in a larger mounting plate, although multiple outlet points (nozzle mounting points) can be set above the mounting plate. However, this is problematic because drilling the air passages and sealing with steel balls is cumbersome, leading to high material and manufacturing costs. Achieving a double-ring flame requires a dual-air passage structure on the valve body, which complicates the valve body structure and necessitates additional piping connections. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide an air duct adjustment mounting plate that allows for free setting of nozzle position and number, and enables dual-ring fire with only one air intake duct.

[0005] Another object of the present invention is to provide a burner having the above-described gas duct adjustment mounting plate.

[0006] Another object of the present invention is to provide a stove having the above-described burner.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] An airway adjustment mounting plate is characterized in that it comprises: a mounting plate body, and a plurality of outer ring nozzle mounting portions and a central nozzle mounting portion disposed on the mounting plate body; an outer ring airway communicating with the outer ring nozzle mounting portions and a central airway communicating with the central nozzle mounting portions are disposed within the mounting plate body; the central airway is connected to an air inlet connector; the central airway and the outer ring airway are connected through a connecting channel; and a switching valve for controlling the opening and closing of the connecting channel is disposed on the connecting channel.

[0009] As a further explanation of the above scheme, the outer ring nozzle mounting position and the center nozzle mounting position are both located at the top of the mounting plate body, the center air passage and the outer ring air passage are arranged through the bottom of the mounting plate body, and a sealing cover is installed at the bottom of the mounting plate body.

[0010] As a further explanation of the above solution, the mounting plate body and the sealing cover are connected by screws.

[0011] As a further explanation of the above scheme, the air intake connector is connected to the side wall of the central air passage.

[0012] As a further explanation of the above solution, an installation step communicating with the central air passage is provided on the side wall of the mounting plate body, and the air intake connector is installed on the installation step.

[0013] As a further explanation of the above solution, the switching valve includes: a valve body, a telescopic device disposed on the valve body, and a sealing surface connected to the telescopic end of the telescopic device.

[0014] As a further explanation of the above scheme, the side wall of the mounting plate body is provided with a mounting flange for mounting the switch valve. The mounting flange is connected to the central air passage or the outer ring air passage. The sealing surface of the switch valve enters the central air passage or the outer ring air passage to seal the connection end face between the central air passage and the connecting channel or the connection end face between the outer ring air passage and the connecting channel.

[0015] A burner includes: a nozzle mounting plate, a flame distributor seat, a center flame cap, and an outer ring flame cap; characterized in that the nozzle mounting plate is a gas duct adjustment mounting plate as described in any of the above claims.

[0016] A stove, characterized in that it includes a burner as described above.

[0017] The beneficial effects of this invention are as follows.

[0018] 1. By using a switch valve to control the opening and closing of the central air passage and the outer ring air passage, it is possible to achieve the adjustment and combustion of double or triple ring flames through a single air inlet pipe. This simplifies the structure of the valve body, as well as the overall structure of the stove, the number of parts, and the assembly process. The nozzle position and number can be freely set.

[0019] Second, the central air passage and the outer ring air passage run through the bottom of the mounting plate body and are sealed with a sealing cap. The mounting plate body can be completed by die-casting aluminum, which has a simple structure, good sealing performance and low cost. Moreover, the advantage of this mounting plate body over the existing mounting plate structure is that it can set multiple nozzles without the need for multiple drilling and sealing processes.

[0034] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0035] Example 1.

[0036] like Figures 2-6 As shown, an airway adjustment mounting plate includes: a mounting plate body 3, and a plurality of outer ring nozzle mounting portions 35 and a central nozzle mounting portion 36 disposed on the mounting plate body 3. An outer ring airway 34 communicating with the outer ring nozzle mounting portions 35 and a central airway 33 communicating with the central nozzle mounting portions 36 are provided in the mounting plate body 3. The central airway 33 is connected to an air inlet connector 6. The central airway 33 and the outer ring airway 33 are connected through a connecting channel. A switching valve 5 for controlling the opening and closing of the connecting channel is provided on the connecting channel.

[0037] Thus, in actual use, gas enters the central gas passage 33 through the gas inlet connector 6, the switch valve 5 is closed and the connection channel is in an isolated state, and the gas stove is in a low flame state, that is, there is a flame in the center and no flame in the outer ring. Gas can enter the central nozzle 2 through the central gas passage 33 to achieve combustion of the central flame. When adjusted to high flame, the switch valve opens, and the connection channel is in a connected state, allowing gas to enter the outer ring gas passage from the central gas passage. The gas achieves combustion of the dual-ring flame through the central nozzle and the outer ring nozzle. Of course, in other embodiments, combustion of the triple-ring flame can be achieved by adding an outer ring gas passage and an outer ring nozzle, and is not limited to this embodiment.

[0038] Both the outer ring nozzle mounting portion 35 and the central nozzle mounting portion 36 are located at the top of the mounting plate body 3. The central air passage 33 and the outer ring air passage 34 penetrate the bottom of the mounting plate body 3, and a sealing cap 4 is installed at the bottom of the mounting plate body 3. The sealing cap 4 is used to seal the ports of the central air passage 33 and the outer ring air passage 34. This facilitates the machining of the central and outer ring air passages, allows the mounting plate body to be completed using die-cast aluminum, resulting in a simple structure, good sealing performance, and low cost. Furthermore, compared to existing mounting plate structures, this mounting plate structure has the advantage of allowing multiple nozzles to be installed without requiring multiple drilling and sealing processes.

[0039] In this example, the mounting plate body 3 and the sealing cover 4 are connected by screws.

[0040] The air intake connector 6 is connected to the side wall of the central air passage 33. An installation step 31, which communicates with the central air passage, is provided on the side wall of the mounting plate body 3, and the air intake connector 6 is installed on the installation step 31.

[0041] In this embodiment, combined with Figure 7 As shown, the switching valve 5 includes a valve body 51, a telescopic device disposed on the valve body, and a sealing surface 53 connected to the telescopic end of the telescopic device. Preferably, a spring 52 is provided between the telescopic device and the sealing surface 53 to reduce the force exerted by the sealing surface on the part to be sealed and to prevent deformation of the part to be sealed.

[0042] A mounting flange 32 for mounting the switch valve 5 is provided on the side wall of the mounting plate body 3. The mounting flange 32 is connected to the central air passage 33 or the outer ring air passage 34. The sealing surface 52 of the switch valve 5 enters the central air passage or the outer ring air passage to seal the connection end face 37 between the central air passage and the connecting channel or between the outer ring air passage and the connecting channel.

[0043] Furthermore, an outer ring nozzle 1 is installed on the outer ring nozzle mounting portion 35; and a central nozzle 2 is installed on the central nozzle mounting portion 36.

[0044] Example 2.

[0045] A burner includes: a nozzle mounting plate, a flame distributor seat, a center flame cap, and an outer ring flame cap; characterized in that the nozzle mounting plate is the gas duct adjustment mounting plate described in Example 1.

[0046] Example 3.

[0047] A stove, characterized in that it includes a burner as described in Example 2.

[0048] As for the specific structure of the stove, it can adopt existing or future structures, which will not be elaborated here.

[0049] Based on the above description of the structure and principles, those skilled in the art should understand that this invention is not limited to the specific embodiments described above.
