Abstract

PURPOSE:To prevent burner ports from being clogged with fluid by a structure wherein the lower surface of each burner port is made to slant radially and outwardly in the downward direction in order for liquid such as the water or the like adhered to the burner port to allow to flow outwards easily. CONSTITUTION:A nozzle member 12 arranged at the upper end 7 of a burner main body 1 consists of a substrate 13 and a cap 14 covering the substrate 13. The underside of the cap 14 provides with a first expanded part 21, which spreads radially and outwardly from the substrate 13 in the radial and outward direction of burner ports 19, a second expanded part 22, which spreads further radially and outwardly from the first expanded part 21, and a drooping part 23, which droops from the second expanded part 22. The top surface 34 of the cap 14 gently slopes radially and outwardly in the downward direction. The water, which is scattered and adhered to the burner ports 19 during cleaning, tends to flow radially and outwardly along the lower surface 20 of each burner port 19. Said water flows down along the outer peripheral surface of the skirt part 16. Thus, the burner ports 19 are prevented from being clogged with water.

Description

[Detailed description of the invention] Technical field The present invention relates to a gas burner that uses fuel gas.

BACKGROUND ART Gas burners installed in kitchen gas ranges and the like are easily contaminated with oil and the like. Therefore, it is necessary to clean using water or the like. Conventionally, when cleaning with water, the water adheres to the flame hole due to its surface tension phenomenon.

Therefore, ignition will not occur in flame holes that are blocked by water.

Purpose An object of the present invention is to provide a gas burner that facilitates the removal of all liquid such as water adhering to the flame hole.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention. Fuel gas is forced into the passage 2 of the burner main body 10 of the gas burner 30, which is formed in a roughly L-shape, from the nozzle 4 toward the throat portion 3. As a result, combustion air is sucked from the air intake port 5.

The entire opening area of the air intake port 5 can be adjusted by the throttle member 6. The upper end 7 of the burner body 1 projects upward from a through hole 9 formed in the top plate 8 of the sink. A short cylindrical portion 10 defining a through hole 9 is erected on the top plate 8 to prevent water from entering the through hole 9 during cleaning.

The upper end 7 of the burner body 1 has a vertical axis and is shaped like a right cylinder. A stepped portion 11 is formed on the outer periphery of the upper end portion 7 . A nozzle member 12 is attached to the upper end portion 7 of the burner body 1 . Jin's crater moon 12 is the base 13 and its base 1
3 and a cap 14. The base body 13 has an upper end s
7 is fitted into a cylinder part 15 which is rotatably supported around a vertical axis by a step part 11, and a skirt part 16 which spreads outward in the radial direction from the cylinder part 15. The skirt portion 16 widens outward in the radial direction as it goes downward, and covers the short cylindrical portion 10 gold.

Referring to FIG. 2, grooves 17 are formed at the upper end of the cylindrical portion 15 at full intervals in the circumferential direction. This groove 17 is open upward. A protrusion 18 formed on the lower surface of the cap 14 partially fits into the groove 17 . In this way, the flame hole 19 is formed.

The flame hole 19 and therefore the lower surface 20 of the groove 17, the base 130
Slants downwardly and radially outward.

The lower surface of the cap 14 has a first enlarged portion 21 extending radially outward from the base body 13 on the radially outer side of the flame hole 19, and a second enlarged portion 21 extending further radially outward from the enlarged portion 21.
It has an enlarged part 22 and a drooping part 23 that hangs down from the second enlarged part 22.

The top surface 34 of the cap 14 slopes gently downward in the radial direction from the center.

Referring to FIG. 3, a gas range 31 including a plurality of gas heaters 30 is installed in a sink 32. As shown in FIG.

In order to clean the gas burner 30, water such as tap water is emitted from the nozzle 33. At this time, the water is filled with cap 140.
It flows down the top surface 34 and falls from the hanging piece 23. The lower end of this hanging piece 23 is located below the flame hole 19,
Therefore, it is possible to prevent water from entering the flame hole 19 during cleaning as much as possible.

Also, since the first and second enlarged portions 21,22 of the cap 14 extend radially outward from the flame hole 19,
The first part of the cylindrical part 15 and the skirt part 16 near 9
And water is prevented from adhering near the second enlarged portion 21.22 due to its surface tension.

When cleaning water splashes onto the flame hole 19, it tends to flow radially outward onto the lower surface 20.

This water completely cures the outer peripheral surface of the skirt portion 16 and flows down. In this way, the flame hole 19 is prevented from becoming clogged with water.

The cap 14 and the base body 13 can rotate together around the vertical si. Therefore, even if water adheres to the flame hole 19 and causes clogging, by turning the flame nozzle member 12 consisting of the cap 14 and the base body 13 with your fingers,
The water adhering to the flame hole 19 is scattered by the centrifugal force.

In this way, the water adhering to the flame hole 19 can be easily removed all at once.

Since the skirt portion 16 extends radially outward from the tube portion 10, the space 24 between the tube portion 10 and the skirt portion 16 is
The capillary action of water prevents water from stagnation.

Even if boiling occurs during cooking, the boiling liquid can be poured into flame hole 1.
9 will be prevented. Even if the broth reaches the flame hole 19, it tends to flow down to the outside along the lower surface 20.

Therefore, even if boiling occurs, there is no danger that the flame will go out and raw gas will blow out, making it safe.

Effects As described above, according to the present invention, since the lower surface of the flame hole is tilted downward in the radial direction, liquids such as water adhering to the flame hole can easily flow outward. The occurrence of noise due to the flame hole being clogged with fluid is avoided as much as possible.
