Description

[Detailed description of the invention] The purpose of this invention is to improve the combustion performance by improving the secondary air supply performance while being clean and easy to use, to prevent boiling of broth when using a stove table. It is.

A conventional gas burner and stove table that use gas as fuel will be described in detail with reference to FIG.

50 is a gas staple, 51 is a burner cap, 52 is a burner head, 53 is a mixing tube, 54 is a burner cap 51
55 is a main flame hole, 56 is an inner flame hole, 57 is a main flame formed in the main flame hole 55, and 58 is an inner flame formed in the shape of the inner flame hole 56. , 59 is located on the circumference at a certain distance from the center of the burner cap 51 and the burner head 52, is airtightly separated from the mixing chamber 54, penetrates and is independent, and has an upper end opened on the upper surface of the burner cap 51, and the other end is connected to the main flame. A secondary air hole is opened at the lower surface of the burner head 52 between the hole 55 and the saucer 60, 61 is a trivet, and 62 is a pot.

When an ignition operation is performed using an ignition knob or the like (not shown) of the gas staple 50, a mixture of gas and air flows into the mixing chamber 54 through the mixing pipe 53.

After that, the main flame 5 ejects from the main flame hole 55 and the inner flame hole 56.
7 and 58, and place the pot 62 in place on the trivet 61.
If it is installed, it will heat up.

At this time, if the broth in the pot 62 boils down, it will fall onto the top surface of the burner cap 51 or directly onto the saucer 6°.

The broth that has formed on the upper surface of the burner cap 51 then flows through the secondary air holes 59 or the outer circumferential wall of the burner head 52 to the saucer 6o, so that all of the broth is received by the saucer 60.

Further, as described above, the secondary air hole 59 is provided by the saucer 6o.
Since the vicinity of the opening on the lower surface of the burner head is configured so that the broth does not flow below the saucer 60, for example, the saucer 6o, the secondary air supplied into the secondary air hole 59 is
The main flame 57 must be supplied from around the main flame 57, and a portion of it is supplied to the main flame 57.

Looking at the secondary air supply in this state, main flame 5
7 and the inner flame 58, the flow of secondary air flows from around the trivet toward the main flame 57 and the inner flame 58, whereas the combustion gas flows in the opposite direction, and furthermore, the combustion gas itself is affected by the draft force. , most of the secondary air flowing in from around the trivet is supplied to the main flame 57, and the secondary air hole 5
The secondary air supplied to the inner flame 58 from the inner flame 58 is insufficient.

When air shortage occurs as described above, the combustion state becomes incomplete, and carbon monoxide, unburned gas, etc. are emitted, which is not desirable as a device.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and FIGS. 1 to 7 show an embodiment of the present invention in which gas is used as fuel, and will be described in detail.

In FIG. 1, 1 is a stove table, 2 is an ignition cock, 3 is a burner composed of a burner cap 4 and a burner head 9, 5 is a trivet, 6 is a pot installed on the trivet 5, and 7
1 is a nozzle, 8 is a mixing tube, 10 is a mixing chamber composed of a combination of burner cap 4 and burner head 9, 11 is a main flame hole, 12 is a main flame shaped in the main flame hole 11, and 13 is an inner flame. A flame hole 14 is an inner flame shaped in the inner flame hole 13, and 15 is a flame hole that constitutes the burner cap 4 and the burner head 9 separately or integrally (separated in this embodiment), and is located on the circumference at a certain distance from the center of the burner. The secondary air is air-tightly separated from the mixing chamber 8, penetrates and is independent, and has its upper end opened on the upper surface of the burner cap 4, and the other end opened on the lower surface of the burner head 9 between the main flame hole 11 and the saucer 16. The hole 17 is an air supply port 18a, 1 provided in the saucer 16 between the burner hole 20, which is smaller than the constant temperature diameter in which the secondary air hole 15 is arranged, and corresponds to the outer peripheral wall 21 of the burner head 9.
Reference numeral 8b indicates a draining portion in which a part of the waist burner head 9 is convexed toward the saucer side at the air supply port 17 and the burner hole 20; 19 is a concave portion surrounded by the secondary air hole 15 and the draining portions 18a and 18b; 20 are burner holes provided in the saucer 16, 21
is the outer peripheral wall of the burner head 9.

Note that the combination of the air supply port 17 and the secondary air hole 15 is such that the burner 3 and the saucer 16 do not overlap each other.
is configured and configured as a stove table.

A pot 6 is held in a predetermined position on the stove table 1 by a trivet 5, and when the ignition cock 2 is operated, gas is ejected from the nozzle 7 into the mixing chamber 8, and the ejected gas mixes with the sucked air. The mixture becomes a mixture and reaches the inside of the mixing chamber 10.

After that, the mixture is ejected from the main flame hole 11 and the flame holding hole 13,
The main flame 12 and the inner flame 14 form and burn.

At this time, the necessary secondary air to the main flame 12 and the inner flame 14 was conventionally supplied from around the trivet, but in the present invention, it is supplied from the air supply port 17 provided around the trivet 5 and on the saucer 16.
It is supplied by more people.

Further, when the broth boils down from the pot 6, the flow of the broth flows from the upper surface of the burner cap 4 through the secondary air hole 15 and the outer circumferential wall 21 of the burner head 9 and remains in the saucer 16.

In this case, the air supply port 17 of the saucer 16 is connected to the burner head 9.
be provided between the outer peripheral wall 21 and the burner hole 20;
The air supply port 17 and the secondary air hole 15 do not overlap,
Since the secondary air holes 15 are each provided with draining portions 18a and 18b, the broth is drained by the draining portions 18a and 18b without flowing along the lower side of the burner head 9, and is all received by the saucer 16. It will be done.

As described above, the present invention solves the lack of secondary air supply, which was a drawback of the conventional method, by providing an air supply port in a part of the saucer, and as a result, carbon monoxide is generated due to incomplete combustion due to lack of air. In addition, phenomena such as the release of unburned gas are eliminated.

Furthermore, by providing a drainer for processing the broth, it is possible to direct it to the saucer, making it possible to obtain the same ease of use as in the past.
