Description

[Detailed description of the invention] This invention relates to a gas cooker such as a gas stove, which is configured so that when broth, etc. boils over from the pot during actual use, it collects in the saucer so that it does not fall below the saucer. be.

In a conventional gas cooker such as a gas stove, as shown in FIG. By the time they reach the burner head 25, they become almost a mixture and reach the main burner 26.

Further, a portion of the gas flowing in from the gas supply port 21 is guided to the pilot nozzle 28 via the pilot conduit 27, and is ignited by piezoelectric spark discharge in the pilot burner section 29 to form a pilot flame 30.

The pilot flame 30 then ignites the main burner 26 through a gap 32 between the main burner 26 and the saucer 31 to form a fire 33.

In this state, a pot or the like is placed on the trivet 34, and when it boils, the broth overflows from the pot and spills onto the saucer 31 and the main burner 26.

In this case, in the conventional structure described above, the main burner 2
Since a gap 32 for igniting the main burner 26 is provided between the main burner 26 and the saucer 31, the boiling liquid spilled onto the main burner 26 enters the gas stove 22 through the gap 32, and the bottom of the gas stove 22 It had fallen down through the gap and stained the top of the gas stove stand.

In order to eliminate the above-mentioned drawbacks, in European gas ranges, etc., the gap 32 between the main burner 26 and the saucer 31 is
However, this method had a problem with ignition.

In other words, in Europe and elsewhere, match ignition is generally the main method, but recently, as shown in Fig. 5, a direct ignition method has been adopted in which the discharge terminal 35 is projected above the saucer 31 and a spark is blown between it and the main burner 26 to ignite it. It's starting to get taken away.

Therefore, in this configuration, the boiling liquid, etc. does not fall downward from the saucer 31, but the sauce, etc. will harden on the discharge terminal 35, causing discharge failure, and since the saucer 31 cannot be removed, it is difficult to clean the saucer 31, etc. There were some aspects that did not match the actual situation.

The present invention has been devised to solve the above-mentioned conventional problems, and the present invention will be explained below based on drawings showing embodiments thereof.

In FIGS. 1 and 2, reference numeral 1 denotes a main body of a gas cooking device such as a gas stove, and a gas supply port 2 faces the side wall of the main body 1.

3 is a nozzle communicating with the gas supply port 2, 4 is a mixing tube, and 5 is a main burner installed in a burner head 6 located at the end of the mixing tube 4, which is located above the top surface of the gas cooker main body 1. ing.

Reference numeral 7 denotes a saucer installed on the upper surface of the gas cooker main body 1, and the diameter of the installation hole 8 of the main burner 5 is made smaller than the outer diameter of the main burner 5 so that the saucer 7 receives all the boiling liquid and the like.

9 is a pilot conduit, and a pilot nozzle 10 is provided at the tip thereof.

11 is a pilot burner, 12 is a discharge electrode, and 13 is a trivet installed on the outer peripheral edge of the saucer 7.

Reference numeral 14 denotes a guide part provided at an arbitrary position on the saucer 7 so that the flame 15 of the pilot burner 11 comes out toward the main burner 5, and this guide part 14 is inclined.

Reference numeral 16 denotes an opening formed with a rising portion H between the end of the guide portion 14 and the saucer 7, and this opening 16 opens diagonally with respect to the horizontal surface of the saucer 7.

The discharge electrode 12 is attached to the lower part of the guide part 14 so that the electrode is not burned out by the flame 17 of the main burner 5 and the flame 15 of the pilot burner 11.

Further, the end of the guide portion 14 is configured to cover the diagonally opened opening 16, thereby preventing the overflowing broth from the pot from falling downward from the saucer 7.

Further, this guide portion 14 serves to guide the flame 15 of the pilot burner 11 when the main burner 5 is ignited, and since the flame 15 of the pilot burner 11 is formed above the saucer 7, the ignition of the main burner 5 is prevented. can be done smoothly.

Figures 3 and 4 show other embodiments.
This also solves the problems that were a concern in the embodiments shown in Figures and 2.

That is, in the embodiments shown in FIGS. 1 and 2, there is a problem that if the positional relationship between the pilot burner 11 and the main burner 5 deviates, the main burner 5 cannot be ignited by the flame 15 of the pilot burner 11. , and in those where combustion is started and stopped by a valve,
As a procedure for using a gas cooker, first, the flame 15 of the pilot burner 11 is formed by operating the valve, and at the same time gas is ejected from the pilot nozzle 10, and the ignition of the main burner 5 by the flame 15 of the pilot burner 11 is completed. After checking, flame 1 of pilot burner 11
5 is stopped.

Therefore, when using a gas cooker, use the pilot burner 11.
The flame 15 of the pilot burner 11 disappears and is used only by the flame 17 of the main burner 5, but if the flame 15 of the pilot burner 11 has been formed for a long time at the beginning of use,
Even after the ignition of the main burner 5 is completed, the flame 15 of the pilot burner 11 comes into contact with the surroundings of the guide part 14 of the saucer 7, and as a result, in extreme cases, the guide part 1 of the saucer 7
If the saucer 7 is heated and becomes red hot, and the area changes color, or if the saucer 7 has been subjected to enameling treatment, there is a problem that the enameling treatment may be destroyed or discolored.

In addition, if you start using the saucer 7 with boiling liquid spilled on it before use, the saucer 7 will be exposed to the flame 1 of the pilot burner 11.
5, the temperature of this saucer 7 is 180-200℃.
When the temperature exceeds ℃, boiling liquid etc. generally causes a burning phenomenon.

As a result, when cleaning the saucer 7, it becomes difficult to remove the dirt due to burn-in, and cleaning takes time and effort.

Furthermore, since the opening has a rising portion H, even if boiling liquid or the like spills, it will not flow into the main body.

In order to solve this problem, in the embodiment shown in FIG. 3, a pilot burner 11a is inserted into the guide portion 14 of the saucer 7.

In this case, another guide part 18 is formed on the saucer 7 so as to be located below the guide part 14 of the saucer 7 and to serve as a guide for fixing the pilot burner 11a.

Therefore, the pilot burner 11a is separated from the guide section 18.
held in place by

As a result, even if vibrations, shocks, etc. are applied, the positional relationship between the pilot burner 11a and the main burner 5 will not change, and the pilot burner 11
The main burner 5 can be ignited by the flame 15 of a.

The discharge electrode 12, which ignites the pilot burner 11a, should be protected from being excessively heated by the flame 15 of the pilot burner 11a and the flame 17 of the main burner 5, or from spilling boiling liquid during use, causing discharge failure. In order to do this, it is provided in the pilot burner 11a.

Furthermore, if the pilot burner 11a is largely protruded above the saucer 7 and placed above the position where the flame 17 of the main burner 5 is formed, the pilot burner 11a may be heated by the combustion of the flame 17 of the main burner 5 and burnt out. do.

In this way, when the distance between the part of the pilot burner 11a where the flame 15 is formed and the part where the flame 17 of the main burner 5 is formed is short, the pilot burner 11a
There is a problem that the flame 15 of the pilot burner 11a burns out, and if it is long, the flame 15 of the pilot burner 11a will burn out.
As a result, the flame 17 of the main burner 5 may not burn or an explosion may occur due to a delay in ignition.

Therefore, for this distance, the pilot burner 11
The length of the pilot burner 11a is shorter than the length of the flame 15 of the main burner 5, and the tip of the pilot burner 11a and the guide portion 14 of the saucer 7 are positioned below the flame 17 of the main burner 5 so as not to be directly heated.

Fig. 4 shows an example in which an opening 19 is provided in the saucer 7, and a pilot burner 11b having an inverted U-shaped cross section is projected from this opening 19 in a positional relationship within the conditions described in the above explanation, and is fixed. It is.

The pilot burner 11 b is provided with a flame hole 20 to form a flame 15. For example, this flame hole 2
If the fourth pilot burner 0 is installed directly above the pilot burner 11b, the broth etc. will enter the pilot burner 11b.
In the figure, to prevent this, the pilot burner 11
It is provided so as to be inclined on the side surface near the upper end of b.

As described above, the gas cooker of the present invention allows the main burner to be ignited smoothly, and all the broth that overflows from the pot is stopped by the saucer and falls downward from the saucer. This makes it easy to use, as it eliminates the hassle of cleaning the gas stove stand after use.
