Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an exhaust system for a combustor such as a gas stove with a grill.

(Prior Art) As shown in FIGS. 6 and 7, a conventional device of this type includes a frame c having an opening b facing the upward outlet a' of the exhaust passage a, and Lid bodies d are arranged facing each other with a gap above, and the lid body d
A leg body e extending downward from the frame body c and a leg body e fixed to the frame body c is known.
(See Publication No. 156811).

(Problem to be solved by the invention) However, the above conventional device has a lid body d and a leg body e.
There may be variations in the angle between the legs during machining, or the lid may be deformed during heat treatment such as enamel finishing, which is commonly performed after the lid d is attached to the frame c by fixing the legs e to the frame c. The body d tends to descend at its tip side, and when the body d is attached to the combustor main body and the combustor is used, this is undesirable as the exhaust resistance increases by the amount of descent, resulting in poor combustion.

(Means for Solving the Problems) The present invention attempts to solve the above-mentioned disadvantages of the conventional device, and is an exhaust device provided at an upward outlet of an exhaust passage, in which an opening facing the outlet is formed. a frame body, a lid body facing each other with a gap above the opening, and legs extending downward from the lid body and fixed to the frame body; It is characterized in that the portion surrounded by is formed by bending upward, and the lid body is supported by the bent piece formed by the bending.

(Function) The present invention has the above-mentioned configuration. According to this, the lid is supported by a bent piece other than the legs, so the angle between the lid and the legs is always maintained at a predetermined angle. When the combustor is used by being attached to the combustor main body, exhaust is performed well.

(Example) Next, an example in which the present invention is applied to a gas stove with a grill will be described based on the drawings.

In the drawing, 1 indicates the stove body, 2 indicates the grill storage installed therein, and the grill storage 2 has an opening/closing door 3 on the front thereof.
It is equipped with a gas burner 4 for cooking on the upper part thereof, a gas burner 5 for smoke roasting connected to the rear side thereof, and an exhaust passage 6 at the rear thereof.

The exhaust passage 6 is bent upward at the rear of the stove body 1 to form an outlet 6a.

Reference numeral 7 denotes an exhaust device provided above the outlet 6a, and the exhaust device 7 includes a frame 8 in which an opening 8a facing the outlet 6a is formed, and a lid disposed facing each other with a gap above the opening 8a. It consists of a body 9 and legs 10 extending downward from the lid 9 and fixed to the frame 8.

In this embodiment, the width of the frame 8 is made the same as the width of the stove body 1, and an opening 8a is formed approximately in the middle of the frame 8, which is slightly larger than the width of the outlet 6a. slightly larger than the width of the frame 8.
The opening 8a may be formed over substantially the entire surface.

Reference numeral 11 denotes a mounting piece for mounting the exhaust device 7 to the stove body 1 at the mounting portion 1a on the back surface thereof.

The above configuration is not particularly different from the conventional example, but in the present invention, the opening 8a is formed by bending the portion of the frame 8 surrounded by the cutting line 12 upward, and the bent piece 13 formed by the bending is formed by bending the opening 8a upward. It supports the lid 9, and more specifically, the tip of the bent piece 13 is supported by the lid 9.
The lid body 9 is also supported by the bent piece 13, which is fixed by welding or the like to approximately the middle of the back surface in the front and back direction, thereby making the support more effective and allowing the exhaust gas to flow smoothly from above to the front.

When doing so, the lid body 9 is connected to the leg body 10 and the bent piece 1.
3, the front end side (tip side) of the lid body 9 does not fall, and even if there are variations in the angle between the lid body 9 and the legs 10 during processing such as sheet metal processing, the lid body When fixing the exhaust device 9 to the frame 8, the front end side does not fall even if the angle is corrected to a predetermined angle or heat treatment such as enamel finishing is performed. Therefore, this exhaust device 7 is attached to the stove body 1. There is no increase in exhaust resistance.

In the figure, 14 is a gas burner for ignition, 15 is an oxidation catalyst filter, 16 is a stove, and 17 is an operating knob.

In the above embodiment, the bent piece 13 is inserted into the opening 8.
1 which is approximately the same width as the opening 8a located at the rear edge of a.
Although the opening 8a is configured with two pieces, it may be configured with two pieces located at both ends of the rear edge of the opening 8a.

In the above-described embodiment, the opening 8 of the exhaust guard 7
Although the bent piece 13 is formed on the rear edge of the opening 8a, the bent piece 13 may be formed on the front edge or side edge of the opening 8a.

(Effects of the invention) As described above, according to the invention, the lids arranged facing each other with a gap above the opening of the frame can be used not only as legs but also as folded pieces formed when the opening is formed. However, since it is supported, even if there are variations in the angle between the lid and the legs during processing, the angle will be corrected to the specified angle when fixing the lid to the frame, or even if heat treatment such as enamel finishing is applied. Unlike the conventional example described above, the lid body does not fall down, and therefore, when this exhaust device is attached to the combustor body, the exhaust resistance does not increase as in the conventional example described above. This has the effect of eliminating combustion defects. Furthermore, since the lid is supported by the bent pieces formed when forming the opening of the frame, it is possible to provide the lid at a lower cost than when the lid is supported by a separate member from the frame.
