That is, since the gas burner is located in the upper part of the furnace and the distance between the bottom of the kettle and the ejection tip of the gas burner is extremely small, the combustion flame hits the bottom of the kettle and excessively heats the kettle, and There was a problem that it was easy to burn food. In addition, since the gas verte is located inside the furnace body, the exhaust gas is likely to remain inside the furnace body during combustion, and it is difficult for the gas to completely burn, resulting in poor combustion efficiency and increased gas consumption. .

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a gas stove for a cooker that can cook food without burning and with good combustion efficiency and heating efficiency. To aim.

<Means for Solving the Problems> In order to achieve the above object, the gas stove for a boiling cooker according to the present invention has a stove main body having an upper opening and a lower opening for mounting a pot, A ceramic fiber inner cylinder is vertically arranged so that its upper end is located in the upper opening and its lower end is located in the lower opening, and the thermal insulation inner cylinder is formed in a funnel shape with upper and lower openings. A large number of exhaust holes are provided in the peripheral wall of the heat insulating material inner cylinder, and an exhaust passage communicating with the exhaust hole is formed between the heat insulating material inner cylinder and the wall of the furnace body. The gas burner is connected in communication and is arranged near the lower end of the heat insulating material inner cylinder so as to have a large space between the gas burner and the bottom of the kettle.

<Operation> In the gas stove for a boiling cooker configured as described above, the cooking stove is placed in the upper opening of the stove main body so that the bottom is inserted into the inner tube of the heat insulating material, and the gas burner is installed. The gas emitted from the igniter is ignited to cook the food.

Combustion exhaust of the gas burner is exhausted from the exhaust holes of the heat insulating material inner cylinder through the exhaust passage on the outside thereof, but because the internal space of the heat insulating material inner cylinder where the flame of the gas burner is generated is large, exhaust is performed well. , The gas burns well and completely. In addition, the inner cylinder is a ceramic fiber heat insulating material, and its fiber diameter is thicker and glassy compared to asbestos, so the inner cylinder itself reflects heat toward the kettle without storing heat, Therefore, heating can be performed with high thermal efficiency. Moreover, since the position of the gas burner is near the lower end of the furnace main body, that is, the inner tube of the heat insulating material, and its position is low, the gas flame does not directly contact the bottom of the kettle and the kettle is not overheated. ,
Boiled food can be cooked well without burning.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a plan view of a gas stove for a cooker, and FIG. 2 shows a sectional view thereof.

Reference numeral 1 denotes a circular box-shaped furnace main body, and an upper opening and a lower opening for mounting a kettle are formed on an upper portion of the furnace main body 1, and for example, a ceramic fiber is layered on an inner wall of the furnace main body. The heat insulating material 2 is attached. further,
Inside the furnace main body 1, a ceramic fiber heat insulating material inner cylinder 3 is vertically arranged so that its upper end is located in the upper opening of the furnace main body 1 and its lower end is located in the lower opening of the furnace. . The heat insulating material cylinder 3 is formed by molding a ceramic fiber into a substantially funnel shape having upper and lower openings, and a large number of exhaust holes 4 are formed in a peripheral wall portion thereof.

Further, an exhaust passage 5 is formed between the heat insulating material inner cylinder 3 and the wall portion of the furnace main body 1, that is, immediately outside the exhaust hole 4. An exhaust passage 6 to which an exhaust duct 7 is connected is provided on one side of the furnace main body 1, and the exhaust passage 6 communicates with the exhaust passage 5. Reference numeral 8 denotes a heat-resistant sleeve for the sight window which is arranged so as to be inserted from the side portion of the furnace main body 1 to the heat insulating material inner cylinder 3.

The gas burner 10 is arranged near the lower opening of the furnace body 1, that is, near the lower end of the heat insulating material inner cylinder 3. Boiler pot 11
Is placed so that its bottom is inserted into the heat insulating material inner cylinder 3 through the upper opening of the furnace main body 1, and the distance between the bottom of the kettle and the gas burner 10 at that time is, for example, the height of the gas flame. 2 ~
It is formed sufficiently large so as to be about three times as large.

A stirring blade of the stirrer is inserted into the pot 11 from above as necessary.

In the cooking stove having the above-described structure, the cooking stove 11 is placed in the upper opening of the cooking stove main body 1 so that the bottom thereof is inserted into the heat insulating material inner cylinder 3. The gas ejected from is ignited to heat the pot 11.

During combustion, the primary air of the gas burner 10 enters from the lower opening of the furnace main body 1, and the combustion exhaust thereof passes from the exhaust hole 4 of the heat insulating material inner cylinder 3 to the exhaust passage 5 on the outside thereof and further to the exhaust passage 6.
Is exhausted from the exhaust duct 7. The pot 11 is not directly heated by the flame of the gas, but is heated by the burning hot air, and the food in the pot is cooked.

In such a gas stove, since the inner space of the heat insulating material inner cylinder 3 in which the flame of the gas burner 10 is generated is large, the air supply and exhaust are favorably performed, and the gas is favorably completely burned. In addition, the heat insulating material inner cylinder 3
Is a ceramic fiber insulation material, and its fiber diameter is thicker and glassy than asbestos,
Since the inner cylinder itself does not store heat and reflects it toward the pot 11, it can be heated with high thermal efficiency.

Furthermore, since the position of the gas burner 10 is near the lower end of the furnace main body 1, that is, the heat insulating material inner cylinder 3, and its position is relatively low, the gas flame does not directly contact the bottom of the kettle 11 and It is not overheated, and the food can be cooked well without burning.
