Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stove, and more particularly, to a stove that can sufficiently suppress the dissipation of exhaust gas. [Prior Art] Conventionally, in such a stove, a gas burner is installed in a restricted space formed on the back side of a top plate, and an exhaust port is formed in a side wall of the restricted space to send exhaust gas from the gas burner out of the restricted space. However, an opening for convection heating of the container to be heated by bringing the exhaust gas from the gas burner into contact with the part of the top plate where the container to be heated is placed is formed with a diameter larger than the outer diameter of the gas burner, and the opening is restricted. An exhaust device that sucks and exhausts exhaust gas from the space was connected to the exhaust port.

When the container to be heated is placed in the opening of the top plate, the opening is covered with the container to be heated, so that exhaust gas can be effectively sucked and exhausted from the restricted space in which the gas burner is installed by the exhaust device. This suppresses the dissipation of exhaust gas into the surrounding area (see, for example, Japanese Patent Laid-Open No. 128481/1983).

[The problem that the idea attempts to solve]

However, in the above-mentioned conventional stove, the exhaust port is formed in the side wall of the restricted space, and the exhaust gas is sucked in from a position outside the side of the gas burner. When a container to be heated is not placed in the opening, the suction effect of exhaust gas is reduced in the inner part of the gas burner that is located away from the exhaust port and the part on the opposite side of the exhaust port, so a large amount of exhaust gas is generated. There was a problem with the radiation dissipating into the surrounding area.

In view of the above-mentioned circumstances, an object of the present invention is to provide a stove that can sufficiently suppress the dissipation of exhaust gas to the surroundings even when no container to be heated is placed thereon.

[Means to solve the problem]

The characteristic configuration of the stove according to the present invention is that an annular gas burner is installed in a restricted space formed on the back side of the top plate, and exhaust gas from the gas burner is sent to the back side of the gas burner through a central hole of the gas burner. an opening for convection heating the container to be heated by bringing exhaust gas from the gas burner into contact with a portion of the top plate on which the container to be heated is placed, and facing the exhaust port; The exhaust device is formed to have a smaller diameter than the outer diameter of the gas burner and is connected to the restricted space for sucking and exhausting exhaust gas from within the restricted space through the exhaust port, and its functions and effects are as follows. That's right.

[Effect]

In other words, when the container to be heated is placed in the opening of the top plate, the opening is covered with the container to be heated, so that the exhaust gas can be effectively sucked and exhausted from the restricted space in which the gas burner is installed by the exhaust device. can.

In addition, when the container to be heated is not placed in the opening of the top plate, the exhaust gas from the annular gas burner can be uniformly sucked from the exhaust port in the central hole of the gas burner over the entire circumference, and the suction effect is reduced. In the outer peripheral part of the gas burner, the peripheral part of the opening in the top plate is opposed to the outer peripheral part, which effectively suppresses the decrease in the suction effect, and the exhaust gas from the gas burner is exhausted. The device allows effective suction and exhaust.

[Effect of idea]

As a result of the above, it has become possible to provide a stove that can sufficiently suppress the dissipation of exhaust gas to the surroundings, regardless of whether the container to be heated is mounted or not.

〔Example〕

Next, an example will be described.

FIGS. 1 and 2 show a stove with an integrated grill, in which a stove part 2 is disposed in the upper part of an appliance casing 1, and a grill 3 is disposed in the lower part thereof.

In the stove part 2, a restricted space 6 that communicates with the combustion air intake 5 is formed on the back side of the top plate 4, and a container to be heated A placed on the top plate 4 is placed in the restricted space 6. An annular gas burner 7 for heating is installed inside. An exhaust port 10 is formed in the central hole of the gas burner 7 to send exhaust gas from the gas burner 7 to the back side of the gas burner 7.

A heating opening 8 is formed in the portion of the top plate 4 on which the container A to be heated is placed, facing the exhaust port 10 and having a diameter smaller than the outer diameter of the gas burner 7. The exhaust gas from the gas burner 7 is brought into direct contact with the heated container A through the opening 8, so that the heated container A is heated by convection.

The diameter of the heating opening 8 is such that when a container A to be heated (pan or frying pan) of a normal size is placed thereon, the heating opening 8 is closed.

Note that 9 in the figure is a trivet on which a small-diameter heated container A' is placed.

The exhaust gas from the gas burner 7 is transferred to the heated container A,
After applying convection heating to A', it is led out from inside the restricted space 6 into the lower grille 3 through the exhaust port 10 formed in the center hole of the annular gas burner 7 by the suction and exhaust action of the exhaust fan 11. The interior space of the grille 3 is also used as a part of the exhaust passage, and exhaust air is concentrated from the exhaust top 12 at the rear of the appliance casing through the interior space of the grille.

That is, when using the stove section 2, the exhaust gas is sucked and exhausted from the restricted space 6 by the exhaust fan 11 with all or most of the heating opening 8 closed by placing the container to be heated A to A'. By doing so, the dissipation of exhaust gas to the surroundings is prevented or effectively suppressed, thereby avoiding exhaust gas contamination of the surrounding atmosphere.

In addition, when the containers A to A' to be heated are not placed in the heating opening 8, the exhaust gas from the annular gas burner 7 is discharged through the exhaust port 10 in the central hole of the gas burner 7.
This is due to the fact that the suction can be uniformly applied over the entire circumference through the gas burner 7, and that the peripheral edge of the heating opening 8 in the top plate 4 is opposed to the outer peripheral portion of the gas burner 7 where the suction effect is reduced. By working together with the ability to effectively suppress the reduction in the suction effect, the exhaust gas from the gas burner 7 can be effectively sucked and exhausted by the exhaust fan 11, thereby effectively dissipating the exhaust gas to the surroundings. It's suppressed.

Incidentally, the exhaust gas that is concentratedly exhausted from the exhaust top 12 at the rear of the appliance casing is efficiently exhausted outdoors by the range hood or ventilation fan installed above the appliance because of the concentrated exhaust.

In the figure, reference numeral 13 denotes a porous plate-shaped ceramic heat radiator that radiates heat toward the heated containers A and A' as it is heated by the passing exhaust gas. The aim is to improve

Further, in the figure, 14 is an opening/closing door of the grill 3, and 15 is a grill burner.

[Another example]

Next, another embodiment will be described.

(B) The opening formed in the part of the top plate 4 on which the container to be heated A is placed may be a group of small holes 8a appropriately distributed as shown in FIG. 3, and the specific shape of the opening may vary. Improvements are possible.

(B) As shown in Figure 4 A and B, heated container A,
An auxiliary tool 16 may be provided to change the size of the opening 8 according to the size of A'.

(c) Regarding the exhaust device that sucks and exhausts exhaust gas from the restricted space on the back side of the top plate, instead of installing an exhaust fan in the main body of the device as in the previous embodiment, the exhaust path from the restricted space is connected to an external forced exhaust pipe. It is also possible to have a configuration in which the pipe is connected to the

(d) As the gas burner, various types can be used, such as a Bunsen burner 7 as shown in FIG. 5, an infrared burner, etc.
