Description

Technical Field

[0001] The utility model specifically relates to a commercial stove burner with optimized structure. Background Art

[0002] Modern commercial plasma stoves usually use 20KW high-power commercial stoves. Commercial plasma stoves use "high firepower" to meet the needs of restaurants, hotels, banquets, and banquets for fast cooking. At the same time, the dishes cooked with "high firepower" have a good taste. For example, the patent with application number 2023231501345 discloses a commercial stove burner with a rotating arc, including: an inner pot, a plurality of cathode tubes arranged on the bottom plate of the inner pot, a plurality of ceramic tubes corresponding to the cathode tubes, and an anode needle; the cathode tube is a cone that gradually shrinks upward, and the cross-section gradually decreases upward. The patent uses the gradually shrinking conical design of the cathode tube to gradually accelerate the flow rate of the plasma fluid, thereby realizing the effective ejection of the cathode tube and heating the wok. However, as a new type of kitchen cooker, the commercial plasma stove has the problems of high manufacturing cost and the stove head is too heavy and inconvenient to move. In view of the above-mentioned defects, researchers in this field have made technical and structural improvements. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal communication of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical features involved in the different embodiments of the present invention described later can be combined with each other as long as they do not conflict with each other.

[0025] See also Figures 1-2 In the embodiment of the utility model, a commercial stove burner with optimized structure includes: a burner top plate 1, a gas collecting box 2, and a plurality of plasma generators 3;

[0026] Among them, the plasma generator 3 includes a shrink tube 31 as a cathode, an anode cylinder 32 and an insulating ceramic tube 33; the ceramic tube 33 is cylindrical with two ends open and interconnected, and the lower end of the shrink tube 31 is provided with a first annular groove 311, and the upper end of the ceramic tube 33 is embedded in the first groove 311; the radial diameter of the shrink tube 31 is smaller than the radial diameter of the ceramic tube 33; therefore, when the plasma fluid enters the inner cavity of the shrink tube 31 with a relatively small cross-section from the inner cavity of the ceramic tube 33, the flow rate becomes faster, thereby ensuring that the plasma can be effectively ejected from the shrink tube 31 and added to the wok.

[0027] In this embodiment, the shrinkable tube 31 of the utility model is cylindrical with a uniform radial diameter, and is made of high-temperature resistant metal material. Therefore, compared with the conical metal cathode tube in the prior art, the shrinkable tube 31 of the utility model requires less material, thereby saving manufacturing costs; at the same time, the shrinkable tube 31 is much lighter than the prior art.

[0028] In the embodiment of the utility model, the gas collecting box 2 is made of high temperature resistant insulating material, and mica or ceramic material can be used; the ceramic tube 33 is cylindrical with two ends opening and interconnecting, and a second annular embedding groove 331 is provided at the lower end of the ceramic tube 33, and the anode cylinder 32 is embedded in the second embedding groove 331, and a conical arc-starting end 321 is also provided at the center of the anode cylinder 32; the furnace head top plate 1 is fixedly connected to the gas collecting box 2 by screws, and the plasma generator 3 is fixed by clamping; the furnace head top plate 1 is provided with a plurality of mounting holes 11 corresponding to the shrink tube 31, and the upper end of the shrink tube 31 passes through the mounting hole 11 and extends to the outside of the furnace head;

[0029] The ceramic tube 33 is a cylindrical shape with two ends open and interconnected. In the prior art, the anode needle is usually threadedly fixed to the bottom wall of the ceramic tube, which wastes labor costs and time costs in the production process. In addition, the ceramic tube is provided with a bottom wall, so the blank material for making the ceramic tube is more, which increases the cost and weight of the ceramic tube. The utility model adopts a circular anode cylinder 32 and embeds it into the second embedding groove 331 of the ceramic tube 33. The bottom wall of the gas collecting box 2 limits the downward movement of the anode cylinder 32, so that the anode cylinder 32 is fixed in the second embedding groove 331. In the production and installation process, the process is simple, the labor cost is reduced, and the production efficiency is improved; at the same time, compared with the prior art, the ceramic tube 33 of the utility model reduces the bottom wall setting, thereby reducing the material cost and the weight of the ceramic tube 33.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
