DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove burner having an annular burner head and a burner cap mounted on the burner head.

[0002]

2. Description of the Related Art In a burner for a stove, a large number of teeth which are provided on an outer peripheral portion of a lower surface of a burner cap are seated on a seat surface for a burner cap on an outer peripheral portion of an upper surface of a burner head. An annular wall which is seated on the seating surface is vertically provided on an outer peripheral portion of the lower surface of the burner cap, and a plurality of radially spaced holes are formed on the annular wall so as to be separated from a lower end surface of the annular wall. Is formed.

According to Japanese Utility Model Laid-Open No. 49-526,
As shown in FIG. 4, a bearing surface b at the outer peripheral portion of the upper surface of the burner head a
In a burner in which a large number of teeth vertically provided on the lower surface outer peripheral portion of the burner cap c are brought into contact with each other, and a flame hole d is formed by a tooth groove between these teeth, the bearing surface b is inclined downward radially outward. Formed on the tapered surface, the direction of the flame hole d is obliquely downward, and the obliquely upward flange e protrudes outward from the seating surface b.
Are also known.

[0004]

The burner shown in FIG.
Even if boiling liquid flows into the flame hole d due to boiling, the inclination of the seating surface b prevents the boiling liquid from entering the inside of the burner head a and the mixing tube connected thereto. However, in this case, in order to make the flame F of the burner rise, it is necessary to provide an obliquely upward flange portion e, and the boiling juice is accumulated in a valley formed by the seat surface b and the flange portion e, There is a problem that the broth is stuck in the valley and the cleaning is troublesome.

[0005] In view of the above, it is an object of the present invention to prevent the broth from entering or sticking into a burner head and to facilitate maintenance.

[0006]

Means for Solving the Problems In order to solve the above problems,
In the present invention, a burner for a stove provided with an annular burner head and a burner cap mounted on the burner head, the burner cap for the burner cap on the outer periphery of the upper surface of the burner head being provided on the outer periphery of the lower surface of the burner cap. An annular wall seated on a seating surface is provided, and the annular wall is separated from a lower end surface of the annular wall to form a plurality of flame holes in a radial manner. Formed on a tapered surface that slopes downward toward the outside, the inner diameter of the seating surface is made smaller than the inner diameter of the annular wall, and a projecting portion that projects radially inward from the annular wall on the seating surface is formed, A plurality of concave grooves are formed radially on the lower end surface of the annular wall.

[0007] Since the flame hole is formed in the annular wall provided on the burner cap so as to be spaced from the lower end surface thereof, even if the seat surface is formed as a tapered surface inclined downward toward the outside in the radial direction, the flame can be formed. By forming the hole so as to be inclined upward toward the outside in the radial direction, the flame can be made to rise, and the flange portion as in the above-described conventional example is unnecessary.

[0008] Even if the broth flows into the flame hole, the boiled broth is received by the overhanging portion of the seating surface, thereby preventing the broth from entering the burner head. Then, the broth received by the overhang flows radially outward in the concave groove due to the inclination of the seat surface, and is discharged to the outside of the burner head. Therefore, the broth does not accumulate on the seat and stick. In this case, if a bank is formed to protrude upward at the inner peripheral edge of the overhang portion, even if a large amount of broth flows in from the flame hole, the broth is blocked at the bank and the broth enters the burner head. Can be reliably prevented from entering.

Further, normally, gas is blown out through the groove, and flame for stabilizing the flame of the flame hole is formed by the gas blown out from the groove. In this case, if there is a bank,
Thereby, the flow velocity of the gas flowing into the groove is reduced, and a stable flame is formed in the groove, so that the flame holding effect is improved.

If the groove is formed so that the groove depth is deeper on the outer peripheral side than on the inner peripheral side of the annular wall, the flame formed in the concave groove expands upward and approaches the flame of the flame hole. The flame effect is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 designates a glass top type glass stove having a protective ring 3 attached to an opening edge of a window hole 2 formed in the glass top plate. The stove burner 4 faces the ring 3.

The burner 4 for the stove is mounted on a mixing tube 6 supported by a burner support plate 5 attached to the inside of the stove, a burner head 7 connected to the mixing tube 6, and a burner head 7. The burner head 7 is inserted into the protection ring 3 from below and protrudes above the glass top plate 1.

The burner head 7 is annular and has a recess 70 extending in the circumferential direction. Then, a cylindrical portion 81 vertically hanging at the center of the lower surface of the umbrella-shaped main body portion 80 of the burner cap 8 is externally fitted to the upper end of the peripheral wall portion 71 on the inner peripheral side of the concave portion 70, and the concave portion 70 is attached to the burner cap 8. And a plurality of gas inlets 72 in the circumferential direction communicating with the mixing pipe 6 are opened in the bottom wall of the recess 70 so that the space between the recess 70 and the burner cap 8 is formed in the gas distribution chamber 9. It is composed.

A seating surface 74 for the burner cap 8 is formed on the outer peripheral portion of the upper surface of the burner head 7, that is, on the upper surface of the peripheral wall portion 73 on the outer peripheral side of the recess 70. An annular wall 82 suspended from the outer periphery of the lower surface of the main body 80 is seated. A plurality of flame holes 83 are formed in the annular wall 82 radially apart from the lower end surface thereof,
The gas from the gas distribution chamber 9 is blown out through these flame holes 83 to form the main flame F. In addition, the flame hole 83
Are inclined upward outward in the radial direction so that the main flame F rises.

The inner diameter of the seating surface 74 is smaller than the inner diameter of the annular wall 82, and the seating surface 74 is formed with a projection 74a that projects radially inward from the annular wall 82. Also, the overhang portion 74
On the inner peripheral edge portion a, a bank portion 75 protruding upward, which is opposed to the lower portion of the inner peripheral surface of the annular wall 82 with a gap therebetween, is formed. Further, the seat surface 74 is formed in a tapered surface inclined downward toward the outside in the radial direction, and the lower end surface of the annular wall 82 is also formed in a similar tapered surface.

A plurality of grooves 84 are formed radially on the lower end surface of the annular wall 82. As shown in FIG. 2, each groove 84 is located at the center of the arrangement pitch of the flame holes 83, and a small flame F ′ formed by gas ejected from the groove 84 has a flame holding effect on the main flame F. I am getting it. Here, the flow velocity of the gas flowing into the concave groove 84 is
Therefore, the combustion state of the gas ejected from the groove 84 is stabilized, and the flame holding effect is improved. Further, the concave groove 84 is formed such that the groove depth is deeper on the outer peripheral side than on the inner peripheral side of the annular wall 82, and therefore, the small flame F ′ expands upward and approaches the main flame F, and the flame holding is performed. The effect is further improved.

The main body portion 80 of the burner cap 8 is formed with a cooling portion 85 which projects outward from the annular wall 82.
Although the inflow of boiled liquid into the flame hole 83 is temporarily prevented by the refrigerated portion 85, when a large amount of spillage occurs, the boiled liquid may flow into the flame hole 83 along the lower surface of the refrigerated portion 85. However, even if boiled liquid flows in from the flame hole 83, the boiled liquid is received by the overhang portion 74a, and even when a large amount of boiled liquid flows in, the bank 75
The boiled liquid is blocked by the
Invasion of the broth to 0 is prevented. The flowing broth flows radially outward in the concave groove 84 due to the inclination of the seat surface 74 and is discharged to the outside of the burner head 7. Therefore, the broth does not accumulate on the seating surface 74, and the boiled juice does not stick.

In the above-described embodiment, the flame hole 83 is formed by machining in the annular wall 82 integrally formed on the lower surface of the main body 80 of the burner cap 8, but as shown in FIG. And the annular wall 82 are formed separately from each other, and in addition to the concave groove 84 at the lower end of the annular wall 82, a groove at the upper end which becomes the flame hole 83 may be formed by forging or the like. Drilling is not required, and costs can be reduced. In this embodiment, a projection 86 is formed on the lower surface of the main body 80 at the pitch of the groove for the flame hole 83 to engage with the upper inner peripheral surface of the annular wall 82. Against annular wall 82
Is positioned.

In the above embodiment, the burner cap 8 is a disk-shaped full cap that covers the annular burner head 7 over its inner diameter (the inner peripheral space of the inner peripheral wall 71). However, an annular burner cap having a central opening facing the inner diameter of the burner head 7 may be used. Further, the burner head 7 may be formed in a non-annular shape without the inner peripheral side wall portion 71. In this case, as a matter of course, the entire surface cap is used as the burner cap 8.

The burner used for a glass-top type stove has been described above, but the present invention can be similarly applied to burners used for other stoves. Further, in the above embodiment, the burner head 7 and the mixing tube 6 are formed as separate members, but the present invention can be similarly applied to a burner in which the burner head 7 and the mixing tube 6 are integrally formed.
