Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a gas burner using combustion gas.

BACKGROUND TECHNOLOGY Gas burners installed in kitchen gas ranges and the like are easily contaminated with oil and the like. Therefore, it is necessary to clean it 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 liquid such as water adhering to the flame hole.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention. Combustion gas is force-fed from a nozzle 4 toward a throat portion 3 into a passage 2 of a burner body 1 formed in a roughly L-shape of a gas burner 30 . As a result, combustion air is sucked from the air intake port 5.
The opening area of the air intake port 5 can be adjusted by the throttle member 6. Upper end 7 of burner body 1
protrudes 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 . This crater member 1
2 consists of a base body 13 and a cap 14 that covers the base body 13. The base body 13 includes a cylindrical portion 15 into which the upper end portion 7 is fitted and rotatably supported around the vertical axis by the stepped portion 11, and a skirt portion 16 that extends outward in the radial direction from the cylindrical portion 15. .
The skirt portion 16 widens radially outward toward the bottom and covers the short tube portion 10.

Referring to FIG. 2, grooves 17 are formed at the upper end of the cylindrical portion 15 at intervals in the circumferential direction. This groove 17 is open upward. In the groove 17,
A protrusion 18 formed on the lower surface of the cap 14 is partially fitted. In this way, the flame hole 19 is formed. The flame hole 19 and therefore the lower surface 20 of the groove 17 are
The radially outward direction of the base body 13 is slanted downward.

The lower surface of the cap 14 includes a first enlarged portion 21 that extends radially outward from the base body 13 in the radial direction of the flame hole 19, and a second enlarged portion 22 that extends further radially outward from the enlarged portion 21. It has a drooping portion 23 that hangs down from the second enlarged portion 22 .
The top surface 34 of the cap 14 slopes gently downward from the center in a radial outward direction. The skirt portion 16 has a space 2 between it and the outer peripheral surface of the short tube portion 10.
form 4. The hanging portion 23 hangs downwardly around the entire outer periphery of the cap 14, and as clearly shown in FIG.
The grooves 17 are spaced radially outward from the lower surface 20 of the groove 17 and extend downward.

Referring to FIG. 3, a gas range 31 including a plurality of gas burners 30 is provided in a sink 32. As shown in FIG. In order to clean the gas burner 30, the nozzle 3
Dissipate water such as tap water from step 3. At this time, the water flows down the top surface 34 of the cap 14 and the hanging piece 2
It falls from 3. The lower end of this hanging piece 23 is located below the flame hole 19, so that water from entering the flame hole 19 during cleaning is prevented as much as possible. Further, since the first and second enlarged portions 21 and 22 of the cap 14 spread outward from the flame hole 19 in the radial direction, the first and second enlarged portions of the cylinder portion 15 and the skirt portion 16 near the flame hole 19 2
1 and 22, water is prevented from adhering due to its surface tension.

When cleaning water splashes onto the flame hole 19, it tends to flow radially outward along the lower surface 20. This water flows down along the outer peripheral surface of the skirt portion 16. 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 a vertical axis. Therefore, even if water adheres to the flame hole 19 and causes clogging, the water adhering to the flame hole 19 can be removed by turning the nozzle member 12 consisting of the cap 14 and the base 13 with your fingers. It 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 cylindrical portion 10, water is prevented from accumulating in the space 24 between the cylindrical portion 10 and the skirt portion 16 due to water capillary action.

Even if boiling over occurs during cooking, the boiling liquid is prevented from entering the flame hole 19. Even if the broth adheres to the dripping flame hole 19, it tends to flow down to the outside along the lower surface 20. Therefore, even if boiling over occurs, there is no risk of the flame going out and raw gas blowing out.
It's safe.

Effects As described above, according to the present invention, since the lower surface of the flame hole is inclined downward in the radial direction, liquids such as water adhering to the flame hole easily flow outward, and therefore the flame Clogging of the holes with fluid is avoided as much as possible.

In particular, according to the invention, the upper end 7 of the burner body 1
In addition, since the nozzle member 12 having the base body 13 and the cap 14 is made removable, the vicinity of the flame hole of the nozzle member 12 can be removed from the upper end 7 and cleaned separately from the burner body 1. This makes cleaning work extremely easy.

In addition, the nozzle member 12 having the flame hole is easily damaged by use of the gas burner, and in this case, only the nozzle member 12 can be replaced and the burner body 1 can be continued to be used as is, so maintenance is easy. is easy.

Furthermore, according to the present invention, the plurality of grooves 17 formed in the upper part of the base body 13 in the crater member 12
A protrusion 18 formed at the bottom of the cap 14 is partially fitted into the cap 14, so when cleaning the cap 14, etc., by pinching the cap 14 with your fingers and rotating the cap 14 around the axis of rotation that extends vertically, you can The base body 13 also rotates, so even if a relatively large amount of water enters the flame hole formed by the groove 17 and the protrusion 18, it will not be blown away by the large centrifugal force. can. Therefore, the vicinity of the upper end 7 of the burner body 1 and the nozzle member 12 can be easily washed with water, resulting in good workability.

Further, in the present invention, a space 24 is formed between the skirt portion 16 of the base body 13 and the outer peripheral surface of the short cylindrical portion 10,
This prevents boiled liquid and water during cleaning from entering the short cylindrical portion 10 radially inward due to capillary action, and also facilitates drying.

Furthermore, the short cylindrical portion 10 of the present invention prevents water and the like from entering the through hole 9 and causing contamination.

Further, according to the present invention, the hanging portion 23 is formed on the outer peripheral edge of the cap 14 so as to hang downwardly over the entire circumference, and the hanging portion 23 is formed in the outer peripheral edge of the cap 14 so as to hang down downwardly over the entire circumference.
Since it is spaced apart from the lower surface 20 in the radial direction and extends downward, it is advantageous in that it can reliably prevent water from going around the lower surface of the cap 14 and entering the flame hole during cleaning. effect is achieved.
