CONSTITUTION:A thick deck plate 2 is installed on the upper side of a body of a device and a feed air port 3 is provided at a proper point of the body and also an exhaust cylinder 4 is vertically installed at the rear side of the body, while an opening 10 for mounting a kettle holder 8 is provided in the plate 2 and a burner 11 is disposed at a location deep in the body corresponding to the opening 10 and a distance is provided between a burner port and the opening 10 and the plate 2 is formed by covering a thick board 5 of insulating material with metallic thin plate 6. As a result, heat radiation from the holder 8 and the plate 2, particularly heat radiation due to local overheating of the plate 2 by combustion gas and heat radiation due to entire temperature rise, are prevented and at the same time heat radiation from a flame or combustion gas is reduced, thereby restraining the temperature rise in a kitchen due to heat radiation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commercial stove.

[0002]

2. Description of the Related Art As is well known, a stove has a burner installed inside the body, and a deck having an opening corresponding to the flame hole of the burner is installed on the upper side of the body. Gokutoku is attached to the claw, and a cooking container such as a pan or frying pan is placed on the claw to cook. In the conventional stove, the Gotoku is configured such that the height from the upper surface of the deck to the upper surface of the pawl portion is relatively high at about 20 to 30 mm in the mounted state. Air supply and exhaust necessary for combustion of the burner are performed through a gap between the bottom surface of the cooking container and the opening. On the other hand, the burner is installed so that the flame hole portion is located close to the opening portion.

[0003] In addition, mainly on a commercial stove, Gotoku is installed not only on the opening but also on the entire surface of the deck so that the pot can be laterally displaced from above the burner. There are many things.

[0004] In such a stove, all the combustion gas of the burner passes from the opening to between the claws of the Gotoku, heats the heat around the cooking container, then diffuses upward and is guided to the hood. At this time, Gotoku becomes hot by being heated by the flame and combustion gas of the burner. On the other hand, when the heating power is strong or the cooking container is small, the flame spreads from between the five virtue claws to the periphery of the cooking container.

[0005]

The conventional stove has the following problems. The claw part which becomes high temperature in use is constructed at a relatively high position, and the radiation area to the surroundings is large, so the amount of radiant heat is large and the kitchen room becomes hot and the environment is deteriorated. In the case where Gotoku is installed on the entire surface of the deck, such as a commercial stove, the point becomes more noticeable, and a large amount of radiant heat is generated, making the kitchen room even hotter. As mentioned above, when the heating power is strong or the cooking container is small, the flame spreads from between the pawls of Gotoku to the surroundings, so heat radiation from the flame and high-temperature combustion gas is added, making the kitchen room even hotter. .. It is heavy and uneven, and it is difficult to clean. The present invention aims to solve such problems.

[0006]

In order to solve the above-mentioned problems, in the present invention, a thick deck is installed on the upper side of the body,
An air supply port is provided at an appropriate position of this body, and an exhaust tube portion is provided on the rear side so as to form an opening for mounting the Gotoku on the deck, and a burner is provided at a deep position of the body corresponding to the opening. We propose a stove in which a space is provided between the flame hole and the opening, and the deck is formed by covering the surface of a thick plate of a heat insulating material with a thin metal plate.

[0007]

[Operation] Since the air supply and exhaust necessary for combustion of the burner installed deep inside the body are also performed through the air supply port and the exhaust tube portion provided in the body, The gap between the annular supports of Gotoku may be narrow. Therefore, Gotoku can be configured so that the step between the upper surface of the pawl and the upper surface of the deck can be made small, or no step can be provided at all. In this case, the flow velocity of the combustion gas through the gap becomes faster, and The heat transfer coefficient is improved, and therefore, even if a part of the combustion gas escapes from the exhaust tube portion, the thermal efficiency as a whole does not decrease.

By virtue of having the above-mentioned structure, the Gotoku has a small radiation area with respect to its surroundings, and in combination with the thick deck, the Gotoku does not need to be installed in another adjoining place of the Gotoku to prepare a cooking container. Since the support can be stably performed in a state where the ridges are shifted, the radiation area can be significantly reduced as compared with the case where other Gotoku are installed. Moreover, such a structure of Gotoku makes it easy to clean the top surface of the hob.

As described above, since a part of the combustion gas of the burner moves toward the rear side of the deck and is discharged from the exhaust tube portion, the rear surface of the rear side of the deck is heated by the combustion gas. Therefore, if the deck is a mere thick plate made of metal, it will be heated by the combustion gas, and the surface will also become hot due to heat conduction, but in the present invention, the deck is a thick plate of heat insulating material. Since the surface is covered with a thin metal plate, the thermal conductivity is low, and therefore the deck is not overheated, so that there is no increase in radiant heat amount due to a locally high temperature part. The radiant heat from the deck is further reduced by making the metal thin plate glossy.

Further, since a distance is provided between the burner's flame hole and opening, the flame may spread from the space between the Gotoku's claws to the surroundings even when the heating power is strong or the cooking container is small. There is also little heat radiation from flames and hot combustion gases.

[0011]

Embodiments of the present invention will now be described with reference to the drawings.
In the figure, reference numeral 1 is a body, which is made of a thin steel plate or the like, and a thick deck 2 is installed on the upper side thereof. An air supply port 3 is provided on the bottom plate in an appropriate place of the body 1, and in the embodiment, an exhaust tube portion 4 is provided on the rear side.

The deck 2 is constructed by coating the surface of a thick plate 5 of a heat insulating material with a stainless steel plate 6 as a thin metallic plate having a luster. If the thin metal plate has a luster, a hard chrome-plated steel plate or the like can be used instead of the stainless steel plate. In the embodiment, the stainless steel plate 6 does not cover the lower surface of the thick plate 5 of the heat insulating material except for the folded-back portion 7 on the lower side.

The deck 2 is provided with an opening 10 in which a step 9 for mounting the Gokutoku 8 is formed. A burner 11 is installed at a deep position of the body 1 corresponding to this opening 10 and the burner 11 is installed. A distance is provided between the flame hole and the opening 10. In the embodiment, the burner 11 is installed at a position where the distance between the upper end of the flame hole and the surface of the deck 2 is 40 to 50 mm.

The exhaust cylinder portion 4 is a double cylinder, and a heat insulating material 12 is mounted between the inner cylinder and the outer cylinder on the front side. As described above, the air itself between the inner cylinder and the outer cylinder may be used as the heat insulating layer without mounting the heat insulating material 12. In addition, in the embodiment, the heat insulating material 13 is also installed on the rear side surface of the body 1.

The Gotoku 8 has an annular support 14 and the opening 10
The annular supporting portion 14 has a thickness equal to the height of the step portion 9, and the pawl portion 15 also falls within the thickness of the annular supporting portion 14. In this way, they are installed in a centripetal manner. Therefore, Gotoku 8
The ring-shaped support portion 1 when mounted in the opening 10.
The upper surfaces of both 4 and the pawl portion 15 are flush with the upper surface of the deck 2. The annular support portion 14 of Gokutoku 8 is formed with an inclined surface 16 for improving the flow of combustion gas.

Further, reference numeral 17 is a mark receiver installed around the burner 11, and the mark receiver 17 is arranged to be supported by being mounted on a support base (not shown). still,
Reference numeral 18 is a cock, 19 is a stand, 20 is a cooking container such as a pot, and 21 is a waste container.

When used in the above-mentioned configuration, most of the combustion gas from the flame hole portion of the burner 11 is usually Gotoku 8
The gas is discharged into the room through the gap 22 between the annular support portion 14 and the bottom of the cooking container 20. However, when the bottom of the cooking container 20 is large and the gap 22 is narrow, a part of the combustion gas is a unit. It moves through the inside of 1 and moves backward, and is discharged from the exhaust tube portion 4. On the other hand, the combustion air enters the container 1 through the air supply port 3 and is supplied to the burner 11. Therefore, even if the gap 22 between the bottom surface of the cooking container 20 and the annular support portion 14 of the Gotoku 8 becomes narrower than the case where the conventional Gotoku 8 is used, the air supply and exhaust necessary for the combustion of the burner 11 are excellent. Done. The gap 2
When 2 is narrow, the flow velocity of the combustion gas passing therethrough is increased, and therefore the heat transfer coefficient with the cooking vessel 20 is improved.
Even if part of the combustion gas escapes from the exhaust tube portion 4, the thermal efficiency as a whole does not decrease. In Gokutoku 8, the inner peripheral diameter of the annular support portion 14 is appropriately made larger than that of the conventional Goutoku 8 and the inclined surface 16 is formed on the upper inner periphery of the annular support portion 14 to easily secure the necessary exhaust area. At the same time, the combustion gas moves so as to scoop the cooking container 20, so that the heat transfer coefficient is improved at this point. It should be noted that the inclined surface 16 is not necessarily provided when the inner peripheral diameter of the annular support portion 14 is sufficiently large.

As described above, since a part of the combustion gas of the burner 11 moves in the rearward direction of the deck 2 and is discharged from the exhaust tube portion 4, the rear surface of the rear side of the deck 2 is heated by the combustion gas. However, since the deck 2 is constructed by covering the surface of the thick plate 5 of the heat insulating material with the thin metal plate 6, the thermal conductivity is low, and therefore the deck 2 is locally overheated or wide due to heat conduction. Since the range does not reach high temperature, the radiant heat quantity does not increase due to the high temperature part. The metallic thin plate 6 has a luster like a stainless steel plate or a steel plate whose surface is hard-chrome plated, so that the radiant heat amount can be further prevented from increasing.

On the other hand, the upper surface of the claw portion 15 of the Gotoku 8 is the deck 2
By making the upper surface of the cooking machine flush with the upper surface of the cooking container 20 and eliminating the steps or reducing the steps, it is possible to stably support the cooking container 20 in a shifted state. It is not necessary to install another Gotoku adjacent to. Therefore, the amount of heat radiated from Gotoku is greatly reduced compared to the conventional one. Gokutoku 8 has hard chrome plating on the surface or by polishing to give it a glossy finish.
Radiant heat is further reduced.

Since a distance is provided between the flame hole portion of the burner 11 and the opening portion 10, the flame does not spread from the gap to the surroundings even when the heat power is strong or the cooking container 20 is small. Therefore, less heat is emitted from flames and hot combustion gases.

[0021]

As described above, the present invention has the following effects. Gotoku can reduce the level difference between the upper surface of the pawl and the upper surface of the deck, can be made flush with each other, and can be provided only in the part corresponding to the opening of the deck, so the amount of heat radiated from Gotoku can be reduced. It can be reduced. It is possible to prevent the local overheating of the deck due to the combustion gas and the rise in the overall temperature, and it is possible to prevent the radiant heat from the deck from increasing. Even when the heat power is strong or the cooking container is small, the flame does not spread from the space between the pawls of Gotoku to the surroundings, and the amount of radiation heat from the flame and high-temperature combustion gas can be reduced. With the above, it is possible to suppress the temperature rise in the kitchen room due to heat radiation, and it is possible to improve the indoor environment. Easy to clean the top of the stove.
