Description

[Detailed Description of the Invention] The present invention relates to a gas stove incorporating burners with different combustion rates, large and medium.

Conventionally, in this type of gas stove, the positions of the large burner and medium burner are fixed to either the left or right.
There was a problem in that the user could not easily change the position to a convenient position and use it.

The present invention was devised to eliminate the above-mentioned drawbacks, and provides a gas stove with a burner arrangement suitable for the position of the gas stove by simply replacing the burners on the left and right sides.

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows a perspective view of the main body of the gas stove, and FIG. 2 is a sectional view of the gas cock portion of the gas stove showing an embodiment of the present invention.

In the figure, reference numeral 1 denotes a cock body, and a nozzle 5, which is fitted into a gas inlet 4 of a large burner 2 and a medium burner 3, is screwed onto the tip.

6 is a closure cover 8 against the elasticity of the closure presser spring 7.
There is a closure housed inside the gas valve, and its rotating shaft 9 is connected to a gas cock knob (not shown).

Reference numeral 10 denotes a gas inlet which passes through a closure hole 11 of the closure 6 and opens at the upper end 12 of the closure 6.

13 is semi-fixed to the center of a cylindrical hole 14 bored in the upper part of the closure 6 by O-rings 15 and 16 and an auxiliary spring 17 whose elasticity is considerably weaker than the elasticity of the closure presser spring 7 so as to be vertically movable. This is the spindle.

The tip 13' of the spindle 13 always projects from the upper end 18 of the cock body due to the elasticity of the auxiliary spring 17.

A hollow portion 19 communicating with the obturator hole 11 is provided extending downward from the approximate center of the spindle, and a small hole (orifice) A communicating with the cylindrical hole 14 is bored therein.

Reference numeral 20 denotes a gas passage bored in the side wall of the cylindrical hole 14 and communicating with the nozzle 5, and one end of the gas passage 20 is closed by screwing a blind screw 21 into the side of the cock body. .

Incidentally, a small hole B having a larger diameter than the small hole (orifice) A of the spindle 13 is bored in the center of the nozzle 5.

Next, to explain the operation, the above-mentioned FIG. A state in which it is not communicated with the closed hand hole 11 is shown.

That is, in this case, the gas that has passed through the gas inlet 10 and the closed hole 11 passes through the hollow part 19 in the spindle 13, flows out from the small hole (orifice) A, and enters the medium burner 3 through the small hole B of the nozzle 5. Inflow.

Therefore, the gas flow rate is regulated by the small hole (orifice) A having a smaller diameter than the small hole B of the nozzle 5, and an amount of gas suitable for the medium burner 3 can be obtained.

In FIG. 2, when the medium burner 3 and the large burner 2 are replaced, the nozzle 5 is attached to the left end of the large burner 2 at a predetermined position 20, and the nozzle 5 is attached to the tip 13' of the spindle 13. Since the opposing projections 21 are provided,
The spindle 13 is pressed downward against the auxiliary spring 17 by the protrusion 21 .

Therefore, the cylindrical hole 14 and the closed hole 11 are in communication, and the gas that has passed through the closed hole flows out from the small hole (orifice) A and also flows out from the gap between the spindle 13 and the cylindrical hole 14. Therefore, by making this gap sufficiently larger than the small hole (orifice) A, the gas flow rate in this case is mostly regulated by the small hole B of the nozzle 5, and the opening area of the small hole B is smaller than that of the small hole. (Orifice) Since it is smaller than A, an amount of gas suitable for the large burner 2 can be obtained.

In the embodiment of the present invention, the protrusion 21 protruding from the large burner 2
Although the spindle 13 is pressed by the spindle 13, the gas amount can be similarly controlled by attaching a magnet only to the large burner, attracting the spindle, and creating a gap in the O-ring part.

It can also be used as a device for mutually switching between 6B, 13A, 6C or LP gas, which are gases with different calorific values.

For example, when switching from 6B to 13A, the spindle is pushed out by the force of the auxiliary spring and held in the same state as when using a medium burner, and conversely, when switching from 13A to 6B, the spindle is cocked against the elasticity of the auxiliary spring. All you have to do is push it inside the main body and hold it there.

As explained above, according to the present invention, in a gas stove equipped with a plurality of burners having different combustion amounts arranged in parallel and a gas cock having a nozzle facing the burners, the discharge port of the closure and the nozzle are connected. In the gas passage between the nozzles, there is a variable means for changing the gas outflow amount by external operation, and the variable means adjusts the gas outflow amount ejected from the nozzle to supply an amount of gas suitable for burners with different combustion amounts. The system is equipped with a gas cock that allows the user to easily replace the burners with different combustion volumes that face the nozzle of the gas cock. It is very convenient because it can be easily changed to a convenient position suitable for the gas stove.

Further, in the production process of this type of gas stove, there is no need to produce two types of models each equipped with a large burner on the left and right sides, and only one type is required, which is convenient for production management.

Claims (1)

[Scope of utility model registration request] In a gas stove equipped with a gas cock that has a nozzle facing the burner and a plurality of burners with different combustion amounts arranged in parallel, gas is injected by external operation into the gas passage between the outlet of the closure and the nozzle. A gas cock which has a variable means for changing the outflow amount, and which adjusts the outflow amount of gas ejected from the nozzle by the variable means and supplies an amount of gas suitable for burners with different combustion amounts, and is opposed to the nozzle of the gas cock. What is claimed is: 1. A gas stove which can be freely replaced with a plurality of burners having different combustion amounts, and wherein one of the burners is provided with a protrusion for operating the variable means when the burner is installed.
