Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a grill device mainly used at home.

(Prior art) Conventionally, an exhaust passage extending rearward is provided at the rear upper part of the firing chamber, and a heat source such as a burner for smoke burning is provided in the passage to burn the smoke discharged from the firing chamber to make it smokeless and odorless. The grill device is known.

(Problems to be Solved by the Invention) This device uses a heat source provided on at least one of the upper and lower surfaces of the exhaust passage to burn out the smoke within the exhaust passage. In this case, there is basically a relationship between the smoke burning ability of the heat source and the heat source, such that the greater the amount of heat, the greater the smoke burning ability. However, in terms of energy and the heat-resistant structure of the exhaust passage, if the heat source is a gas burner, a large amount of heat, that is, a large amount of combustion, will tend to obstruct the flow of exhaust gas from the kiln. It is desirable to have less. The inventor of the present invention conducted various tests on changes in the heat amount of the heat source and how the smoke is burnt out, and found that when the heat source's heat amount is large, the smoke is burnt out and is not exhausted from the exit of the exhaust passage.
It was found that when the amount of heat from the heat source decreases, the smoke is exhausted without being completely burned out, and this only occurs partially, rather than over the entire area at the exit of the exhaust passage.

In view of this fact, an object of the present invention is to provide a grill device that can burn away smoke with a smaller amount of heat from a heat source.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an exhaust passage extending rearward at the rear upper part of the kiln chamber, and a heat source for smoke combustion is provided in the passage. It is characterized in that the amount of heat of the heat source for burning smoke is made larger at both sides of the passage than at the center in the transverse direction.

(Function) In the grill device having the above configuration, it is possible to prevent the temperature on both sides of the exhaust passage from becoming lower than the center without increasing the amount of heat of the entire heat source for smoking, and to prevent the temperature on both sides of the exhaust passage from becoming lower than the center. The emitted smoke can be burned out.

(Example) An example of implementing the present invention will be described with reference to a grill device incorporated into a stove body.

In the drawing, 1 is the stove body, 2 is a baking chamber that constitutes a grill device on the stove body 1, 3 is a burner as a cooking heat source provided on the top surface of the baking chamber 2, and 4 is a part from the rear upper part of the baking chamber. A burner 5 is provided as a heat source for burning smoke, and in this embodiment, the burner 5 protrudes into the firing chamber 2. It is provided on the upper surface of the front half of the exhaust passage 4 constituted by the partition plate 7, and the smoke burning burner 5 is provided integrally behind the cooking burner 3. 6 is exhaust passage 4
Shows the exit. To further explain this, as is clear from FIG. 2, the cooking burner 3 and the smoking burner 5 are constructed by attaching a ceramic plate 9 with a large number of flame holes 9a to the lower surface of a common burner body 8. However, in the part constituting the smoke-burning burner 5 which is continuous with the part constituting the cooking burner 3, the flame holes 9a of the side parts 5a are made denser than the central part 5b. The amount of heat is made larger at both side portions 5a than at the central portion 5b in the transverse direction of the passage.

To explain this in more detail, the ceramic plate 9 has a large number of four-sided pyramid-shaped projections 9b arranged vertically and horizontally on its surface, and vertical and horizontal grooves 9 between these projections 9b.
As is clear from FIGS. 5 and 6, the central portion 5b of the parts constituting the smoke burning burner 5 has four flame holes 9 in the protrusion 9b.
Eight flame holes 9a are provided in the groove 9c surrounding the part a, and the two side parts 5a of the part constituting the burner 5 are provided with the protrusion as shown in FIG. There are four flame holes 9a in the 9b part, and four more flame holes in the groove 9c surrounding this than in the central part 5b12
By doing so, the amount of heat of the burner 5 for burning smoke is made larger at both side portions 5a than at the center portion 5b. In this embodiment, the flame holes 9a are densely arranged over the entire width of the front end portion 5c of the burner 5 for smoke burning to increase the amount of heat.
In this way, the heat for firing can be applied from the front end portion 5c to the rear part of the firing chamber 2, and in particular, in the illustrated example, the partition plate 7 protruding into the firing chamber 2 constituting the exhaust passage 4 is transparent. A hole 7a is provided, and the through hole 7a
It was made to be applied to the rear part of the firing chamber 2 through.

In addition, the cooking burner 3 and the smoking burner 5
In this way, the burner 3 as a cooking heat source may be configured separately from the burner 3, and is not limited to a plate burner, but may also be a Bunsen burner, and the burner for smoking 5 can be provided not only on the upper surface of the exhaust passage 4 but also on the lower surface of the exhaust passage 4, and furthermore, increasing the combustion amount of the burner 5 on both sides compared to the central part This can also be achieved by providing separate burners with a large amount of heat on both sides of the exhaust passage 4, or by providing burners above and below only on both sides. Further, the heat source is not limited to a burner, but may be an electric heater.

(Effects of the invention) According to the invention having the above configuration, there are the following effects.

It is possible to suppress the temperature of both sides of the exhaust passage from being lower than the central part without increasing the amount of heat of the entire heat source for smoke burning, and to burn out the smoke discharged through the exhaust passage. Furthermore, since the amount of heat of the entire burner is not increased, deterioration and damage to the walls and the like constituting the passage due to heat can be suppressed as much as possible.
