DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention mainly relates to an oven,
It relates to a firing device such as a fish firing device or a meat firing device.

[0002]

2. Description of the Related Art Conventionally, a gas burner for cooking is exposed to the upper part of a baking oven, and a gas burner for roasting smoke generated during firing to make it smokeless and odorless is exposed to a smoke discharge passage. It is known from Japanese Utility Model Laid-Open No. 60-106004.

[0003]

However, in the prior art, any of the smoke roasting burners is located at or near the outlet of a smoke discharge passage located at a position distant from a cooking gas burner facing a firing chamber. It is provided in the part.

[0004] For this reason, there is a problem that oil contained in the smoke generated in the firing chamber adheres to the smoke discharge passage, and that cleaning of the smoke is difficult.

A gas burner having a function of roasting smoke is also known from Japanese Patent Publication No. 47-8680.

However, this method has a problem that the structure of the gas burner is complicated because a function for smoke roasting is added to the gas burner for cooking.

Further, Japanese Patent Application No. 63-928, which is a prior application of the present application.
As disclosed in the specification of No. 16 and the drawings, there is also proposed an apparatus in which a gas burner for roasting smoke is directed downward on an upper surface in a smoke discharge passage to burn smoke in the smoke discharge passage.

By the way, in order to bake smoke well, it is necessary to contact the gas burner with the smoke.

Therefore, in the prior application of the present application, in order to bake smoke effectively, it is conceivable to narrow the upper and lower widths of the smoke discharge passage so as to improve the contact between the smoke and the gas burner for roasting smoke. However, if you narrow the upper and lower width of the smoke discharge passage,
Smoke is hardly discharged from the firing chamber, exhaust gas is trapped in the firing chamber, and there is a possibility that each part of the firing apparatus may be overheated or combustion failure may occur.

An object of the present invention is to obtain a sintering apparatus free of these problems.

[0011]

According to the present invention, in order to achieve the above object, a sintering apparatus according to the first aspect of the present invention is a sintering apparatus having a smoke discharge passage extending further rearward from an upper rear portion of a sintering chamber. A gas burner provided with a combustion plate at the opening of a flat burner body, with the combustion plate facing downward, with the rear end of the combustion plate facing the upper part of the smoke discharge passage and the remainder facing the upper part of the firing chamber. Te, attached to the calcining device, constitutes a part facing the smoke discharge passage and the smoke torrefaction functional unit and smoke torrefaction functional unit with a portion facing the firing chamber of the combustion plate and cooking function unit combustion plate Is inclined obliquely upward with the rear as the top.

According to a second aspect of the present invention, the lower wall of the smoke discharge passage is a horizontal plane.

[0013] In the firing device according to the first aspect of the present invention, the combustion plate of the gas burner faces the upper part of the firing chamber to function as a cooking function unit, and fires a food such as fish. When the rear end of the combustion plate of the gas burner faces the upper part of the smoke discharge passage, it functions as a smoke roasting unit. Oil and the like are easily burned.

The rear end of the combustion plate facing the smoke discharge passage exhibits a smoke roasting function, and the remaining portion exhibits a cooking function.
There is no need to separately configure and control the cooking burner and the smoke roasting burner, and the configuration and control of the gas burner are simplified.

Moreover, in order to improve the contact of the exhaust gas with the combustion plate constituting the smoke roasting function part, the smoke roasting function part is constituted even if the vertical width of the smoke discharge passage is narrowed. By inclining the combustion plate obliquely upward with the rear upper, the exhaust in the smoke discharge passage can be encouraged to flow backward by the inclination.

In addition, since the exhaust gas can be satisfactorily exhausted even if the upper and lower widths of the smoke discharge passage are narrowed, it is possible to improve the contact of the exhaust gas with the combustion plate constituting the smoke roasting function part. it can.

In the sintering device according to the second aspect, the vertical space between the smoke discharge passages further increases toward the rear, so that the smoke flows more easily through the exhaust passage than the sintering device according to the first aspect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a gas stove with a grill.

In the drawing, reference numeral 1 denotes a firing chamber, 2 denotes an opening / closing door for closing an opening 3 provided on the front surface of the firing chamber 1, and 5 extends substantially horizontally rearward from an upper rear portion of the firing chamber 1 and has a narrow width in the vertical direction. The smoke discharge passage 5 is shown, and the smoke discharge passage 5 is connected at one end to the upper rear part of the baking cabinet 1 and opens at the other end to the rear end upper surface of the baking cabinet 1. Reference numeral 4 denotes a gas burner in which a combustion plate 4b is provided at an opening of a flat burner body 4a. The rear end faced the upper part of the smoke discharge passage 5 to serve as a smoke roasting function part 6, and the remaining part, that is, the most part, was attached to the upper part of the baking oven 1 as a cooking function part 4 c.

The width of the burner body 4a is the same from the part facing the firing chamber 1 to the part facing the upper part of the smoke discharge passage 5.

The gas burner 4 has a square burner body 4.
a burner plate 4b is provided in an opening provided in the burner body 4a, and a mixing tube 7 provided in the burner body 4a is provided.
Was assembled so as to face the rear side of the firing chamber 1. Since the smoke roasting function section 6 at the rear of the gas burner 4 faces the smoke discharge passage 5 having a narrow width in the vertical direction, it can be maintained at a high temperature required for roasting smoke.

In this embodiment, the gas burner 4 is
The burner flame of the ignition burner 8 is exposed through a through hole 9 provided in the lower side wall of the smoke discharge passage 5 to ignite from the smoke roasting function section 6.

When the fuel gas is discharged from the gas burner 4, it is relatively narrow, so that the portion filled with the fuel gas discharged from the gas burner 4 can be ignited.
In the drawing, reference numeral 10 denotes an auxiliary discharge passage for guiding smoke that may leak through the through hole 9 to the outlet side, and reference numeral 11 denotes an oxidation catalyst provided in the smoke discharge passage 5, and in FIG. catalyst
11 was provided at the exit of the smoke discharge passage 5.

In this embodiment, a plate piece 12 is provided which protrudes from the side of the smoke discharge passage 5 to the side of the firing chamber 1, so that the size of the firing chamber 1 is not changed from the conventional one, and the combustion You can make room for the rear end.
The lower wall of the smoke discharge passage 5 was formed in a horizontal plane.

In FIG. 1, 13 is a cover provided so as to cover the upper surface of the outlet of the smoke discharge passage 5, 14 is a back guard provided on the cover 13, and 15 is a smoke discharge port.

[0026]

Since the present invention is configured as described above, the following effects can be obtained.

According to the first aspect of the invention, the smoke discharged from the firing chamber immediately burns oil contained in the smoke by the combustion plate facing the smoke discharge passage. Therefore, unlike the conventional example, the problem that oil contained in smoke adheres to the wall surface of the smoke discharge passage does not occur.

Further, the rear end of the combustion plate provided at the opening of the flat burner body is positioned above the smoke discharge passage extending substantially horizontally further rearward from the rear upper portion of the firing chamber, and the smoke discharge passage is formed. There is no need to produce a gas burner with a special configuration for smoke roasting because the upper combustion plate performs the smoke roasting function.

Further, in order to improve the contact of the exhaust gas with the combustion plate constituting the smoke roasting function part, the smoke roasting function part is formed even if the vertical width of the smoke discharge passage is narrowed. Since the combustion plate is inclined obliquely upward with the rear side being higher, the inclination can promote the flow of exhaust gas in the smoke discharge passage to the rear, and the flow of exhaust gas in the firing chamber to the smoke discharge passage. Is smoothed, exhaust gas is trapped in the firing chamber, and it is possible to eliminate the possibility of overheating each part of the firing apparatus or causing poor combustion.

According to the second aspect of the invention, the upper and lower spaces of the smoke discharge passage are narrowed on the inlet side in order to improve the contact between the combustion plate constituting the smoke roasting function part and the exhaust gas. However, since the combustion plate that constitutes the smoke roasting function part is inclined obliquely upward with the rear upper, and the lower wall of the smoke discharge passage is a horizontal plane, it spreads out toward the rear and exhausts the smoke discharge passage. Flows easily, and the flow of the exhaust gas in the firing chamber to the rear side can be further improved.
