A stove nozzle mounting structure, a burner and a stove

Abstract

This invention discloses a stove nozzle mounting structure, a burner, and a stove. The structure comprises an assembled upper cover and a base. At least two sets of nozzle mounting platforms are provided on the upper cover. Each set of nozzle mounting platforms includes an outer ring nozzle mounting platform and a central nozzle mounting platform. Each outer ring nozzle mounting platform is connected to a corresponding outer ring gas passage, and each central nozzle mounting platform is connected to a corresponding central gas passage. Both the outer ring gas passage and the central gas passage extend through the upper cover to the base. Multiple gas passages, nozzle mounting platforms, and mounting limits are integrated into the nozzle mounting structure. Although the appearance is somewhat complex, it can be integrally die-cast using a mold, requiring only drilling. The overall processing technology is relatively simple and the processing cost is low. The multiple central and outer ring gas passages allow for the installation of multiple nozzles, enabling a larger load capacity. The nozzle position and number can be freely set.

Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to a stove nozzle mounting structure, burner, and stove. Background Technology

[0002] like Figure 1 As shown, the nozzle installation structure of existing top-intake stoves involves setting a flat structure below the burner, extending the pipe to the required location, drilling through the gas passage using a rotary hole, and then installing sealing steel balls at the rotary hole; or directly leading a single pipe to the area below the nozzle.

[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 will correspond to the number of valve core layers in the valve body. That is, the conventional double-ring valve body leads out two air passages to form two single-ring flames. The single-ring air outlet at one point will lead to uneven gas mixing and combustion, which can only reduce the load. If a mounting plate structure is used, the mounting plate will be larger in size, but multiple air outlets, i.e., nozzle mounting points, can be set on the top of the mounting plate. The disadvantage is that the air passage hole drilling and steel ball sealing are very troublesome, and the material and manufacturing costs are very high. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a stove nozzle installation structure that is simple to produce and process, small in size, and allows for free setting of nozzle position and number.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A stove nozzle mounting structure, characterized in that it comprises: an upper cover and a base assembled together, wherein at least two sets of nozzle mounting platforms are provided on the upper cover, each set of nozzle mounting platforms includes an outer ring nozzle mounting platform and a central nozzle mounting platform, each outer ring nozzle mounting platform is connected to a corresponding outer ring air passage, each central nozzle mounting platform is connected to a corresponding central air passage, and each outer ring air passage and each central air passage extend through the upper cover to the base.

[0007] As a further explanation of the above solution, an installation edge is provided at the bottom of the upper cover, and an installation groove is provided on the base to allow the installation edge to enter.

[0008] As a further explanation of the above solution, an upper mounting hole is provided on the upper cover, and a lower mounting hole corresponding to the upper mounting hole is provided on the base.

[0009] As a further explanation of the above scheme, an outer ring air intake channel communicating with the outer ring air intake channel and a central air intake channel communicating with the central air intake channel are provided on the side wall of the base.

[0010] As a further explanation of the above solution, a limiting baffle for positioning the combustion disc of the burner is provided on the upper cover.

[0011] As a further explanation of the above solution, the upper cover or the base is provided with mounting screw holes for mounting thermocouples and ignition needles.

[0012] As a further explanation of the above solution, the upper cover and the base are provided with clearance holes for the temperature sensor to pass through, the bottom surface of the base is provided with a mounting groove that mates with the temperature sensor, and the mounting groove is provided with a fixing hole for mounting the temperature sensor.

[0013] A top-intake burner, characterized in that it includes a stove nozzle mounting structure as described in any one of the above, a combustion plate disposed on the stove nozzle mounting structure, and a central burner cap and an outer burner cap disposed on the combustion plate.

[0014] A stove, characterized in that it includes the stove as described above.

[0015] The beneficial effects of this invention are: multiple gas passages and nozzle mounting platforms and limiting baffles are integrated on the nozzle mounting structure. Although the appearance is somewhat complex, it can be integrally die-cast using a mold and only requires drilling. The overall processing technology is relatively simple and the processing cost is low. Setting multiple central gas passages and outer ring gas passages can achieve the purpose of installing multiple nozzles and can achieve a larger load. The position and number of nozzles can be freely set. Attached Figure Description
