Description

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

BACKGROUND ART Gas burners installed in kitchen gas ranges and the like need to be cleaned from time to time because oil and other substances adhere to them. Conventionally, when water from cleaning adheres to the flame holes, it is difficult to remove the water from the flame holes due to the decrease in surface tension, and it is necessary to carefully wipe away the water in each flame hole with a cloth. , therefore, the work requires a long time and is troublesome. If the flame hole remains blocked with water, it will not be possible to ignite the flame.

A prior art technique that solves this problem as much as possible is disclosed in Japanese Patent Application Laid-Open No. 146331/1983. This prior art has a configuration in which a burner cap, which is removably placed on the open end of a burner body, is slightly angularly displaced in the circumferential direction by an operating knob that is operated when igniting or extinguishing the burner. This eliminates the condition where boiled liquid and the like adhere to the flame hole due to surface tension and form a bridge.

With such prior art, it is possible to eliminate the adhesion of boiled liquid due to surface tension as described above, but it is possible to eliminate a relatively large amount of boiled liquid, such as when washing the entire upper part of a gas burner with water. It is not possible to remove water that has adhered to the surface. Moreover, the link mechanism that interlocks the operating knob and the cap results in poor workability during washing with water.

Purpose An object of the present invention is to provide a gas burner device that can easily remove a relatively large amount of liquid when washing the upper part of the burner with water and improve the workability of cleaning work. That's true.

This is a gas burner device characterized by including such a crater member 21.

The gas burner device according to the present invention includes a gas burner and a top plate 4, and the gas burner includes a burner body 1, a sliding bearing 20, and a nozzle member 21.

Embodiment FIG. 1 is a sectional view of an embodiment of the present invention.
A gas range installed in a sink is equipped with a burner body 1 according to the present invention. Burner body 1
A passage 2 is formed in which guides fuel gas and combustion air. The upper end 3 of the burner body 1 faces upward, has a vertical axis, and has a right cylindrical shape. A through hole 5 formed in the top plate 4 of the sink protrudes upward from the upper end portion 3. A short cylindrical portion 6 is formed in the through hole 3 .

The passage 2 of the burner body 1 has a portion that slopes downward from an upper end 3, and a throat portion 7 is formed near the lower end. Fuel gas such as city gas is supplied from the nozzle 8 toward the throat portion 7 . Combustion air is sucked into the passage 2 from near the outer periphery of the nozzle 8 through an intake port 9 . The opening area of the intake port 9 is adjusted by a diaphragm member 10. A drainage hole 11 is formed at the bottom of the passage 2. A trap 12 is connected to this drain hole 11, and the trap 12 is led through a pipe 13 to a drain channel of the sink. Water that has entered the passage 2 during cleaning, etc., flows through the passage 2, passes through the drainage hole 11, the trap 12, and is discharged from the drain pipe 13. In the trap 12, liquid such as water is stored and sealed. Therefore, the combustion state of the burner body 1 is not adversely affected. Note that the other end of the conduit whose one end is connected to the drain hole 11 may be immersed in water in the toilet. The burner body 1 is
The bottom plate 1 of the gas range is supported by the support members 14 and 15.
6 is removably attached.

FIG. 2 is a perspective view showing the structure related to the upper end portion 3 of the burner body 1. FIG. An outward facing flange 17 is formed on the upper end portion 3 below the top plate 4.
A sliding bearing 20 made of a heat-resistant material and having a flange 18 and a short cylindrical portion 19 is supported on this outward facing flange 17 . The short cylindrical portion 19 of the slide bearing 20 surrounds the upper end portion 3 of the burner body 1. The collar 18 faces outward and is mounted on the aforementioned collar 17. Short tube part 1
The upper end portion 3 is inserted into the 9, and the short cylindrical portion 19 is inserted into the flange 1.
8 and extends to a position below the upper end of the upper end portion 3 . A skirt portion 25 formed on the base body 13, which will be described later, forms a space 35 between it and the outer peripheral surface of the short tube portion 6.

A crater member 21 is attached to the upper end portion 3. This crater member 21 includes a base body 22 and a cap 23 that covers the base body 22. The base body 22 is
A cylindrical portion 24 into which the upper end portion 3 is inserted, and the cylindrical portion 24
and a skirt portion 25 formed around the outer periphery of the skirt. The skirt portion 25 surrounds the short cylindrical portion 6 and
It covers the area and expands radially outward as it moves downwards. A plurality of upwardly open grooves 27 are formed at intervals in the circumferential direction in the upper part of the cylindrical portion 24 . The outward flange 17 is formed at a midway position between the top and bottom of the upper end portion 3 . The lower end surface of the base body 22 is placed on this outward facing collar 17 so as to be freely rotatable around a rotation axis extending vertically. As is clear from FIG. 1, the groove 27 is formed above the upper end portion 3.
The cap 23 is placed over the upper end surface of the base body 22.

Referring to FIG. 3, the outer circumferential wall of the cap 23 is formed with unevenness 28 arranged in a circumferential direction, and is given a so-called crown finish. A protrusion 29 is formed in the lower part of the cap 23 in the circumferential direction. This protrusion 29 partially fits into a groove 27 formed in the base body 22 from above. As a result, a flame hole is formed in the groove 27.

Referring to FIG. 4, when the gas burner 1 becomes soiled, it can be cleaned by spraying tap water or the like from the shower 31. At this time, water that has entered the passage 2 of the burner body 1 from the flame hole side formed by the groove 27 flows through the passage 2 and is discharged to the outside from the drain hole 11. Therefore, water does not remain in the passage 2.

When the flame hole formed by the groove 27 is closed by water during this cleaning due to the surface tension phenomenon of the water, the cap 23 is rotated around the vertical axis with a finger. As a result, the base body 22 and the cap 23 rotate smoothly by the sliding bearing 20. Therefore, the water in the flame hole is blown outward by centrifugal force. In this way, it is possible to prevent ignition errors. Water splashed from the nozzle 31 flows into the vacuum 32 from the top plate 4 and is discharged from the drain hole 33.

Even if the flame hole is blocked by the boiling liquid flowing into the burner body 1 during cooking, by rotating the crater member 21, the boiling liquid is scattered and the flame hole is blocked. This can prevent clogging.

Effects As described above, according to the present invention, a crater member having a vertically extending rotation axis is provided at the upper end of the passage for guiding fuel gas and combustion air in the burner main body, and the crater member is formed on the peripheral wall of the crater member. When liquid such as water adheres to the flame hole, the gas burner is rotated and the liquid is scattered outward from the flame hole by centrifugal force, making it easy to clean the gas burner. This eliminates the risk of ignition errors. Furthermore, even if boiling over occurs during cooking and the flame hole is clogged with liquid, the liquid adhering to the flame hole can be easily removed.

In particular, according to the invention, the upper end 3 of the burner body 1
In addition, since the nozzle member 21 having the base body 22 and the cap 23 is made removable, the vicinity of the flame hole of the nozzle member 21 can be removed from the upper end portion 3 and cleaned separately from the burner body 1. This makes cleaning work extremely easy.

In addition, the nozzle member 21 having the flame hole is easily damaged when the present gas burner is used, and in this case, only the nozzle member 21 can be replaced and the burner body 1 can continue to be used as is.
Easy to maintain.

Furthermore, according to the present invention, the plurality of grooves 27 formed in the upper part of the base body 22 in the crater member 21
A protrusion 29 formed at the bottom of the cap 23 is partially fitted into the cap 23, so when cleaning the cap 23, etc., by pinching the cap 23 with your fingers and rotating the cap 23 around the axis of rotation that extends vertically, you can The base body 22 also rotates, so even if a relatively large amount of water enters the flame hole formed by the groove 27 and the protrusion 29, it will not be blown away by the large centrifugal force. can. Therefore, the vicinity of the upper end 3 of the burner body 1 and the nozzle member 21 can be easily washed with water, resulting in good workability. In the above-mentioned prior art, only the cap provided at the top of the burner body is configured to be slightly angularly displaced, so it is impossible to reliably remove boiled juice and water that have entered the flame hole. There's a problem. The present invention solves these problems.

Furthermore, according to the present invention, the nozzle member 21 has a base body 22 and a cap 23, and by covering the base body 22 with this cap, a flame hole is formed, so that both 22 and 23 can be removed and connected to each other. Cleaning can be carried out separately, which ensures that the flame hole is cleaned and is easy to maintain. Such a configuration is an excellent effect of the present invention that has not been achieved by the prior art described above.

Further, according to the present invention, the top plate 4 has the first short cylindrical portion 6.
A skirt portion 25 is formed that extends radially outward from above the first short cylindrical portion 6, and a space 35 is formed between the skirt portion 25 and the outer peripheral surface of the first short cylindrical portion 6. form. Therefore, boiled liquid and water from cleaning are prevented from entering the first short cylindrical portion 6 radially inward due to capillary reduction, and drying is facilitated.

Furthermore, the first short cylindrical portion 6 of the present invention prevents water and the like from entering the through hole 5 and staining it.

Furthermore, in the present invention, the base body 2 of the crater member 21
The lower end surface of the slide bearing 20 is connected to the outer second collar 1 of the slide bearing 20.
A sliding bearing 20 is constructed by the second collar 18 and the second short cylinder part 19, and the upper end part 3 of the burner body 1 is inserted into the second short cylinder part 19, so that the burner body 1 The base body 22 of 21 can be rotated smoothly. As a result, water that adheres when washing the crater member 21 with water can be removed from the crater member 21.
It rotates smoothly at high speed and can be thrown away by centrifugal force.

Furthermore, in the present invention, the skirt portion 25 formed on the base 13 prevents boiled liquid and water from entering inward through the through hole 5 of the top plate 8, and also radiates heat. To prevent a slide bearing 20 from becoming abnormally high in temperature. This prevents the sliding bearing 20 from deforming due to heat, and allows it to be used for a long period of time.
Therefore, it becomes possible to rotate the crater member smoothly over a long period of time.
