Abstract

PURPOSE:To improve a resistance against an air flow, facilitate to prevent an overflow of bailing juice and the like by a method wherein a gas burner having a pilot burner is arranged below a grid. CONSTITUTION:Gas injected from a main nozzle 1 is injected from a main flame hole 14, injected further from a gas pilot flame hole 15 through a pilot flame nozzle 9, ignited with an igniter and ignited there and then a combustion occurs at the main flame hole 14. A grid 16 composed of a funnel-like flat plate and claws 16b is mounted on a top plate 8. A gas burner 11 having a main flame hole 14 and a pilot flame hole 15 at a central port 13 is shielded below the grid 16, thereby combustion at the gas cooking unit is made stable without being less influenced by an air flow or the like, and a flame A may heat the bottom part of a cooking container 6 uniformly from its central part toward its outer periphery, resulting in that a thermals efficiency is improved and a less irregular heating is observed. Further, a boiling juice or the like dropped at the cooking unit is directly flowed into a juice receiving pan 19 through an opening 16a of the grid 16, resulting in that the gas burner 11 shows less clogging or stain and the like, and since the pan 19 has a smaller diameter than that of the central port 13 of the gas burner 11, the pan may easily be removed from the main body 8 of the equipment and cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the construction of a gas regulator such as a gas stove, which uses oil or gas as fuel.

Conventional technology As shown in FIG. 3, in a conventional gas stove, the gas flame port 4 is composed of a tooth-shaped outer flame port on the outer periphery of the gas burner 2 and an inner flame port provided on the top surface. The gas flame port 41 is a flame port formed by a constriction of the pipe of the pilot burner 10, and these gas flame port portions 4, 4' are exposed.

The operation of the gas stove configured as described above will be explained below.

First, gas ejected from the nozzle 1 is mixed with primary air in the mixing pipe a of the gas burner 2 and combusted in the gas flame port 4. The cooking container 6 is placed on the trivet 5 for cooking. The soup saucer 7 is placed between the top plate 8 and the gas burner 2. The gas ejected from the nozzle 9 is combusted at the flame port 4' of the pilot burner 10.

Problems to be Solved by the Invention However, in the above configuration, as shown in FIG. 3, during cooking, the flame A of the gas burner 2 overflows from the outer periphery of the cooking container 6, which is uneconomical and causes uneven cooking. is likely to occur. In addition, since the fire power adjustment and pilot flame have exposed flame ports like the gas flame port 4, there is a risk of extinguishment, backfire, etc. when affected by wind. Furthermore, since boiled over water is directly applied to the gas flame port 4, the gas flame port 4 may become clogged.
It gets dirty easily, especially the central hole 2a of the gas burner 2 and the juice pan 7.
If boiled water falls from the gap 10 between the appliance and the appliance, it stains the inside of the appliance and the floor, making it difficult to clean. In addition, the pilot burner is provided independently from the gas burner 2,
This has the problems of a large number of parts, a large number of assembly steps, and a complicated serviceability and configuration.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention arranges a large number of flame holes along the peripheral edge of the central opening, and divides the flame holes into those for the main flame and those for the pilot flame. and a donut-shaped gas burner with different fuel intake passages, and an opening portion rotated relative to the central opening and having a diameter slightly smaller than the central opening, and located above the gas burner 1111 at regular intervals. A trivet is provided and placed so that it can be freely connected to the top plate, and a trivet is arranged below the central opening of the gas burner,
It is equipped with a juice pan having a diameter smaller than the central opening, and a rectifying plate disposed below the gas burner (Ill) at a constant interval to supply secondary air.

According to the above structure, the present invention arranges a gas burner having a pilot burner below the trivet, and the main flame hole and the pilot flame hole are hidden from the center opening of the trivet. Because they are arranged in rows around the circumference of the trivet, there is no spillage and wind resistance is improved, and spillage flows directly into the saucer through the opening of the trivet, making it clean and easy to clean. become.

EXAMPLE Hereinafter, a gas stove employing an example of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, the gas ejected from the main nozzle 1 is mixed with the primary air drawn in by the ejection force of this gas in the mixing pipe 12 of the gas burner 11, and is lined up at the peripheral end of the central opening 13 of the gas burner 11. The gas ejected from the provided main flame hole 14 and the gas ejected from the pilot nozzle 9 are similarly mixed in the mixing pipe 12a of the gas burner 11, which is separated from the mixing pipe 12, and then The flame is ejected from a pilot flame hole 15 arranged in a row in a part of the main flame hole 14 arranged in a row at the peripheral end of the hole, ignited by an igniter and combusted, and then combusted by this pilot flame into the previous main flame hole 14. occurs. The configuration of this gas burner 11 is made possible by press-molding the burners, which have different gas intake paths for the mixing tubes 12.12a, by caulking together the outer peripheral edges of the upper and lower plates of the press burner. ing. Furthermore, by arranging the main flame hole 14 and the pilot flame hole 15 on the same circumference, it is easy to transfer the flame. On the other hand, a trivet 16 consisting of a funnel-shaped flat plate placed on the upper side of the gas burner 11 so that its outer periphery can be separated from the top plate 8 and a claw 16 protruding from this flat plate is placed at a constant distance from the gas burner 11. The secondary air necessary for combustion is supplied from the outer circumferential side through this gap 17, and the combustion flame A is placed on a trivet whose diameter is slightly smaller than the central opening 13 of the gas burner 11. A flame like A is formed above the opening 16a of 16 to heat the cooking container 6.

As described above, according to this embodiment, the gas burner 11, which has the main flame hole 14 and the pilot flame hole 15 provided at the peripheral end of the central opening 13, is concealed below the trivet 16, so that the combustion of the gas stove is prevented. The flame A heats the bottom of the cooking container 6 evenly from the center to the outer periphery as shown in Fig. 2, which improves thermal efficiency and reduces uneven cooking. moreover,
Even in the case of boiling over, the boiling liquid that has fallen onto the stove directly flows into the soup saucer 19 through the opening tea of the trivet 16, so the gas burner 11 is free from clogging, dirt, etc. Also, since the juice tray 19 has a smaller diameter than the central opening 13 of the gas burner 11, it can be easily removed from the appliance body 8 and cleaned.

In addition, by obtaining secondary air from the holes 20a of the rectifier plate 20 provided at a constant interval 20b at the lower part of the gas burner 11, the configuration is such that the secondary air is drawn along the rectifier plate 20, resulting in good combustion. I can do it.

Effects of the Invention As described above, the present invention has a large number of flame holes arranged along the peripheral edge of the central opening, divides the flame holes into main flame and pilot flame, and has a fuel intake path. A donut-shaped gas burner with a different shape, and an opening that faces the central opening and has a diameter slightly smaller than the central opening, and is spaced apart from the top plate by providing a certain interval above the gas burner. A trivet that can be placed freely, a juice pan that is placed below the central opening of the gas burner and has a smaller diameter than the central opening, and a secondary Since it is equipped with a rectifier plate that supplies air, the gas stove has good wind resistance and thermal efficiency, is less likely to clog due to boiling over, and is easy to clean even if it gets dirty. I can do it. In addition, multiple burners (pilot burner and main burner) can be combined, and since the flame holes are arranged on the same circumference,
Fire transfer is guaranteed.
