[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stove burner used for a gas stove.
[0002]
[Prior art]
As this type of burner, for example, as shown in FIG. 1, a cylindrical burner head b is attached to a burner body a, and an annular distribution chamber c connected to the burner body a is provided inside the burner head b. It is known that a gas passage d extending radially from the distribution chamber c is formed on the outer periphery of the burner head b, and the outer end of the gas passage d is configured as a flame outlet e. If the amount of the mixed gas supplied to the burner body a decreases, the flame at the flame outlet e becomes unstable and disappears. Therefore, in order to prevent this, a sheet metal is applied to the burner body a below the outer peripheral side of the flame outlet e. Providing an L-shaped protrusion f made of the same is also performed (Japanese Utility Model Laid-Open No. 3-104613).
[0003]
[Problems to be solved by the invention]
By providing the above-described L-shaped projection f, the mixed gas ejected from the flame port e is decelerated by the projection f, and the generation of the lift flame can be suppressed. In addition, when the amount of the mixed gas is low and the thermal power is low, the supply of secondary air to the vicinity of the flame opening is suppressed by the projection f, and the flame is stabilized by the gas mixture having a high gas concentration between the flame mouth e and the projection f. Can be maintained, and the aperture performance can be improved. However, since the L-shaped protrusion f is provided on the burner body a which cannot be removed, cleaning is not easy when dirt adheres to the burner body a, and since it is made of sheet metal and involves welding work, it is easy to manufacture. In addition, there is a disadvantage that deformation due to impact is likely to occur and durability is poor.
[0004]
It is an object of the present invention to provide a stove burner with good squeezing performance that is easy to clean and can be easily manufactured, has good durability, suppresses the occurrence of lift flames, and stabilizes the flame at low heating power. Is.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has a gas passage that radially extends from the annular distribution chamber inside the burner head made of a metal block attached to the burner body to the outer periphery and has an outer end as a flame opening. In the stove burner, the burner head is composed of a burner head main body that is open above the gas passage and a burner cap that is placed on the burner head and closes the open portion above the gas passage. An advancing portion that extends from the lower side of the flame mouth to the outer circumferential direction is provided on the entire circumference of the outer peripheral portion of the main body , and an inclined surface that is inclined downward toward the outer circumferential direction is formed on the upper surface, and each flame mouth is formed on the inclined surface. Protrusions that push up the flow of the air-mixed gas ejected from the flame port are formed by integral molding only at positions facing the outer peripheral direction of the gas. Moreover, cleaning is further facilitated by providing the burner cap with a flange that covers the top of the protrusion.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. In FIG. 2, reference numeral 1 denotes a burner body 2 made of sheet metal and a cylindrical forging or casting detachably attached to an opening 3 thereof. The stove burner comprised with the burner head 4 made from the metal block made from a thing is shown. Inside the burner head 4, there is an annular distribution chamber 5 that communicates with the inside of the burner body 2 to make the air mixture gas have a uniform pressure distribution, and radially from the distribution chamber 5 to the outer periphery of the burner head 4. A gas passage 6 extending in the direction of the gas passage 6 was formed, and the outer end of each gas passage 6 was formed as a flame port 7.
[0007]
Such a configuration is not different from that of the conventional stove burner, and is ignited and burned by the air mixed gas ejected from the flame port 7. In order to suppress the generation of the lift flame at this time, the burner head 4 is moved to the gas burner. As shown in FIG. 3, the upper portion of the passage 6 is composed of a burner head main body 4a opened by an opening portion 8, and a burner cap 4b which is placed on the burner head main body 4a and closes the opening portion 8. The protrusion 11 is formed by integral molding so as to oppose the outer peripheral direction of the flame port 7 and push up the flow of the air mixed gas ejected from the flame port 7. The width of the projection 11 is formed so as to be able to push up the air mixed gas ejected from the flame port 7, for example, the same width as the flame port 7.
[0008]
An advancing portion 9 that advances from the lower side of the flame port 7 to the outer peripheral direction is provided, and an inclined surface 10 that is inclined downward toward the outer peripheral direction is formed on the upper surface of the advancing portion 9, and the protrusion 11 is formed on the inclined surface 10. By forming the liquid, it is difficult for the liquid to enter the gas passage 6 because the inclined surface 10 is inclined downwardly on the outer periphery of the flame opening 7 even when a liquid such as broth drips on the inclined surface 10. Even if the inclined surface 10 and the protrusion 11 are dirty, the burner head main body 4a can be removed and cleaned, and the dirt in the gas passage 6 can be cleaned at the same time. The projection 11 reduces the jet speed of the air mixed gas jetted from the flame opening 7 and suppresses the generation of the lift flame. Further, the projection 11 suppresses the supply of secondary air at the time of weak heating power, and a stable flame is maintained by the combustion of the gas mixture having a high gas concentration between the flame mouth 7 and the projection 11, and the throttle function, that is, the throttle ratio is improved. In addition, the angle of the flame is increased and the heating efficiency is increased. In addition, by providing the burner cap 4b with the flange portion 12 that covers the upper portion of the protrusion 11, it is possible to prevent the broth and the like from being applied to the inclined surface 10 and the protrusion 11, and to increase the cleaning interval. .
[0009]
The operation of the stove burner 1 having the configuration shown in FIG. 2 will be described. The air mixed gas flowing into the distribution chamber 5 of the burner head 4 from the burner body 2 is ejected from the flame port 7 of the gas passage 6 and burns. The head 4 is divided into a burner head body 4 a having an opening 8 above the gas passage 6 and a burner cap 4 b that closes the opening 8, and an inclined surface 10 is provided on the outer peripheral side of the flame port 7. Since the protrusion 11 that pushes up the flow of the air mixed gas is integrally formed on the outer peripheral end of the advancing portion 9, the manufacture is easy, the positional relationship between the flame opening 7 and the protrusion 11 is accurate, and the durability is good. The gas ejection speed is reduced to suppress the lift flame and the supply of secondary air is suppressed, the throttle performance is improved, and the flame angle is directed upward to improve the thermal efficiency. Further, since the broth and the like are removed to the outside of the burner head 4 along the inclined surface 10, it is difficult to get dirty and easy to clean. The shape of the protrusion 11 is not limited to a quadrangular prism shape and may be spherical.
[0010]
【The invention's effect】
As described above, according to the present invention, the burner head is composed of the burner head main body that opens above the gas passage and the burner cap that closes the open portion. Since the projections that push the flow of the air-mixed gas ejected from the flame opening are formed by integral molding, the projections that suppress the lift flame and improve the squeezing performance can be provided so as not to be contaminated by boiling juice The cleaning can be easily performed by removing the burner head main body, and the projection is integrally formed with the burner head main body, so that it is possible to easily produce a projection having an accurate positional relationship with the flame outlet. Further, by providing the protrusion on an inclined surface formed on the upper surface of the advancing portion that advances from the lower side of the flame mouth to the outer peripheral direction, or by providing a flange portion that covers the protrusion on the burner head, the protrusion can be made more difficult to get dirty.
