Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame leak prevention type stove capable of suppressing the burner flame and the hot air generated by the flame from leaking to the outside of Gotoku.

[0002]

2. Description of the Related Art A conventional stove uses Gotoku with a nail,
The burner's flame and the heat generated by the flame are naturally released to the outside of Gokutoku along the bottom of the pot placed on the claws of Gokutoku. Reaches the handle of the pot and heats it, causing a problem that the handle becomes difficult to hold.

In order to solve such a problem, the applicant of the present application previously provided Japanese Patent Application No. 7-107403 with a tubular Gotoku having a double-walled inner and outer wall structure surrounding a flame of a burner, and the inner peripheral wall of the Gotoku In addition to opening an exhaust window, an exhaust passage communicating with the space between the double walls of Gotoku is provided, and an exhaust fan is provided in the exhaust passage to exhaust the hot air generated by the flame of the burner from the space surrounded by Gotoku. We have proposed a flame leakage prevention type stove that can forcibly suck and exhaust air through the window to prevent the leakage of flames and hot air to the outside of Gotoku.

[0004]

In the flame leak prevention type stove as described above, a pot smaller than the inner diameter of Gotoku cannot be used.
There is a problem that the application is limited. In view of the above points, an object of the present invention is to provide a flame leakage prevention type stove that can be used with pots of various sizes.

[0005]

Means for Solving the Problems In order to solve the above problems,
According to the present invention, a tubular Gotoku, which has a double-walled inner and outer wall structure and surrounds the flame of the burner, is provided with an exhaust window on the inner peripheral wall of the Gotoku, and an exhaust passage communicating with the space between the double walls of Gotoku. In the flame leakage prevention type stove in which an exhaust fan is installed in the exhaust passage and the hot air generated by the flame of the burner is forcibly sucked and exhausted from the space surrounded by Gotoku through the exhaust window, The diameter of the lower part is made smaller than the diameter of the upper part, and a plurality of pot receiving projections are provided at the lower part of the inner peripheral wall at intervals in the circumferential direction, and the exhaust window is opened in the part of the inner peripheral wall above these protrusions. are doing.

According to the present invention, a large pot can be placed and used on the upper end of Gotoku, and a small pot can be placed and used on a protrusion on the lower part of the inner wall of Gotoku. When using a small pot,
Hot air leaks upward through the gaps between the protrusions, and this hot air is sucked and exhausted through the exhaust window located above the protrusions. Therefore, the handle of the pot is not heated by the hot air, rather,
There is an advantage that the heating efficiency is improved because the lower part of the peripheral surface of the pan is heated by the hot air before the hot air leaks from the gap between the projections and is sucked and exhausted to the exhaust window.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a stove main body 1 has a gotoku 3 mounted on a top plate 2 on the upper surface of the stove main body 1. The top plate 2 includes an outer top plate 20 and an inner top plate 21. The Gotoku 3 is formed in a tubular shape having an inner and outer double wall structure and is placed on the upper surface of the inner top plate 21.

Below the inner top plate 21, a bottomed cylindrical combustion casing 4 is provided.
The burner 5 is housed in the combustion casing 4.
The burner 5 is composed of an internal flame type ring burner having a flame hole 5a on the inner circumference, and the flame F of the burner 5 is surrounded by the Gotoku 3 through an opening 21a opened in the central portion of the inner top plate 21. I am trying to rise to. A plurality of ventilation holes 40 are formed in the combustion casing 4, and secondary air for combustion is introduced into the combustion casing 4 through these ventilation holes 40.

A plurality of exhaust windows 31 are opened in the inner peripheral wall 30 of the Gotoku 3 at intervals in the circumferential direction. In addition, the inner top plate 21 has an upper and lower double wall structure, and the upper wall of the inner top plate 21 is in communication with the space between the inner and outer double walls of Goutoku 3 and the space between the double walls of the inner top plate 21. A plurality of holes 21b are formed at intervals in the circumferential direction, and a space between the double walls of the inner top plate 21 is formed in the top plate 2.
An exhaust duct 6 communicating with an exhaust port 6a formed in the inner part of the is provided, and the inner top plate 21 and the exhaust duct 6 constitute an exhaust passage communicating with the space between the double walls of the Gotoku 3. An exhaust fan 7 is provided in the exhaust duct 6, and thus hot air generated by the flame F of the burner 5 is forcibly sucked and exhausted from the space surrounded by the Gotoku 3 through the exhaust window 31.

The inner peripheral wall 30 of the Gotoku 3 is formed in a tapered surface having a smaller diameter toward the lower side, and an embossed projection 32 for receiving a pan and a position lower than the projection 32 are formed on the lower portion of the inner peripheral wall 30. 2 and a claw-shaped protrusion 33 extending inwardly with
As shown in, a plurality of them are provided at intervals in the circumferential direction. Thus, even a small pot P that cannot be placed on the upper end of Gotoku 3 can be used by placing its pot bottom on the protrusion 32, and pots smaller than this can also be placed on the protrusion 33. Can be used.

Providing the projections 32 and 33 at intervals in the circumferential direction is such that when a small pan P is placed, the projections 32 and 3 are provided.
This is because the hot air is discharged from the gap between the three and the hot air is brought into contact with not only the bottom of the pot but also the lower portion of the peripheral surface of the pot P to improve the heating efficiency. However, in this state, the hot air released is the hot pot P.
Rises around and the handle PH of the pan P is heated by hot air. Therefore, in the present embodiment, the exhaust window 31 is opened in the inner peripheral wall 30 of the Gotoku 3 so as to be located above the protrusion 32, and the hot air emitted from the gap between the protrusions 32 and 33 is discharged from the exhaust window 31. It is possible to suck and exhaust.

Further, in this embodiment, the upper end of the Gotoku 3 is substantially level with the outer top plate 20, and the stove top surface is flattened. This is advantageous because the appearance is improved and dirt on the top plate 2 can be easily wiped off.

In the above embodiment, two types of protrusions 32 and 33 are provided on the lower portion of the inner peripheral wall of the Gotoku 3, but
For example, the embossed protrusion 32 can be omitted. In addition, in the above-described embodiment, the claw-shaped projection 33 is provided in the Gotoku 3
Although it is integrated with the above, a sub-Gotoku with a claw that can be mounted is provided on the lower inner circumference of the inner peripheral wall 30 of the Gotoku 3, and the protrusion 3
3 can also be configured.

Further, as shown in FIG. 3, the inner peripheral wall 30 of the Gotoku 3 is formed in a stepped shape having a large diameter at the upper portion and a small diameter at the lower portion, and the projections 34 are circumferentially spaced at the step portion. The exhaust window 31 may be formed in the large diameter portion rising from the step portion.
