Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an improvement in burners for stoves such as gas stoves.

Conventional configurations and their problems For example, in conventional gas stoves, the flame hole shape of the burner has been devised in various ways so that the firepower can be adjusted to a low calorie level with one burner, but depending on the type of gas, Due to differences in combustion, the limit is 6 to 700 Kcal/h for safety reasons such as extinguishing flames.

Therefore, another method is to set up a separate small burner inside the main burner to make it possible to adjust the firepower down to a low calorie level, but this requires space for installing the small burner, flame transfer from the main burner, and flame interference between the burners. There were combustion problems such as soot generation due to interference, and clogging problems due to boiling over.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and aims to provide a burner that allows the heating power to be adjusted to a low calorie level and has good flame transfer and combustion.

Structure of the Invention In order to achieve the above object, the stove burner of the present invention is provided with a communication hole in a part of the main burner body that is independent of the mixing chamber, a small burner installed in the communication hole, and a flame The part of the burner cap that forms the hole corresponding to the small burner is made independent of the flame hole of the main burner, but its end portion is tucked inward from the other flame holes.

This allows you to adjust the heat power of the main burner without making major changes to conventional stove burners.
By extinguishing, it is possible to adjust the firepower to a low calorie level, and even if the main burner and small burner are independent, the burner cap is integrated,
Furthermore, since the diaphragm part has the above-mentioned structure, it is possible to obtain a stove burner with good flame transfer and combustion.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the main burner body 1 has a mixing tube 2 connected to one end, an inner circumferential wall of the other end fits into the cylindrical part of the burner cap 8, and an outer circumferential wall of the burner cap 8. A flame hole is formed with a tooth-shaped flame hole formed in the flame hole.

Next, a communication hole 4 is provided in a part of the mixing chamber 3 sandwiched between the inner circumferential wall and the outer circumferential wall of the main burner body 1, independent of the mixing chamber. A burner 6 is installed by a burner support beam 12.

On the other hand, the burner cap 8 has a tooth-shaped flame hole as shown in Fig. 2, but the part corresponding to the small burner 6 is separated from the flame hole of the main burner.
is a protrusion for positioning. The boundary portion 10 between the main burner and the main burner is recessed inward from the other flame hole portions.

The operation of the above configuration will be explained below.
During combustion in the main burner, gas ejected from the nozzle 5 mixes with air sucked in by the mixing pipe 2 and enters the mixing chamber 3. A combustion flame is formed between the outer peripheral wall of the main burner body 1 and the tooth-shaped flame holes of the burner cap 8.

On the other hand, in the combustion of the small burner, the gas ejected from the nozzle 5 is transferred to the air hole 7 provided in the small burner 6.
It mixes with the air that has been sucked in and is ejected from the tip of the small burner 6, forming a combustion flame in an independent flame hole of the burner cap 8.

Effects of the Invention As described above, according to the present invention, although the small burner is located inside the main burner and the burner cap is also integrated, the small burner and the main burner portion are independent from each other in the flame hole portion. () The firepower can be adjusted over a wide range by adjusting the firepower on the main burner side or extinguishing the fire.

() Since the small burner is located inside the main burner, it is less affected by spills and takes up the same space as a conventional burner.

() The burner cap is integrated with the flame hole of the main burner, and the cut-off portion is tucked inside the flame hole to ensure good combustion without flame transfer or poor combustion due to interference between the combustion flames. can get.

Claims (1)

[Claims] 1. A burner cap having a tooth-shaped flame hole, a burner body having a mixed gas inlet at one end and forming a flame hole at the other end with the burner cap, and a small burner formed in a pipe shape. A small burner is installed in a communication hole provided in a part of the burner main body independently of the mixing chamber of the main body, and a flame hole part of the burner cap is made independent at a position corresponding to the small burner. This stove burner has a structure in which the partition between the burner body and the burner body is tucked inward from the tooth-shaped flame hole.
