Description

Technical Field

[0001] This application relates to the field of fire hole components, and particularly to a fire hole component, burner, and stove. Background Technology

[0002] In traditional gas stoves, the burner design directly affects combustion efficiency and flame stability. Existing burners typically employ a simple orifice structure, where gas is directly ejected through the orifice and mixed with air before combustion. However, this design suffers from the following problems: Incomplete gas-air mixing: Traditional orifice structures lack effective flow guidance, resulting in poor gas-air mixing, incomplete combustion, low thermal efficiency, and the potential production of harmful gases (such as carbon monoxide). Prone to orifice clogging: Traditional orifice structures are usually single-aperture designs, which are easily clogged by grease or food residue after prolonged use, making cleaning difficult and affecting the normal operation of the burner. Inconvenient maintenance: Existing burner orifice components are mostly fixed designs, making disassembly and cleaning complex and increasing user operating and maintenance costs.

The mixed gas is fully mixed, which improves the combustion efficiency.

[0030] In one embodiment, a flow channel is formed between adjacent spaced guide vanes 7.

[0031] In one embodiment, the lower end of the column plate 3 is provided with a lower hole plate 10. The structure of the lower hole plate 10 is the same as that of the upper hole plate 2. Multiple sets of upper hole plates 2, column plates 3 and lower hole plates 10 are stacked to achieve more thorough mixing.

[0032] In one embodiment, the upper hole plate 2, the column plate 3, and the lower hole plate 10 are respectively provided with mounting holes. Positioning screws pass through these mounting holes to install and position the upper hole plate, column plate, and lower hole plate. During cleaning, the positioning screws can be loosened for easy separation and cleaning.

[0033] A burner is also provided, comprising the flame hole assembly 1 described in any of the above claims and a positioning plate 11, wherein a plurality of the flame hole assemblies 1 and positioning holes 12 are evenly distributed on the positioning plate 11.

[0035] The technical advantages of the fire hole assembly, burner, and stove in this application are as follows:

[0036] This utility model discloses a flame hole assembly, burner, and stove. The flame hole assembly 1 comprises an upper perforated plate 2 and a vertical plate 3 stacked together. Gas is thoroughly mixed through a through hole 4, a flow channel formed by adjacent fixed-distance guide plates 7, and a flow hole 8, before being ejected from the flame hole between the upper perforated plate and the vertical plate, resulting in spiral combustion. This process ensures more uniform mixing, more complete combustion, and better heat exchange.
