2. Description of the Related Art As an exhaust structure of a conventional grill cabinet of this type, for example, Japanese Patent Application No. Hei 7-163679 discloses that the burner provided in the grill cabinet is connected to the outer surface of the grill cabinet. The combustion gas discharged into the stove part of the above is covered from above to prevent the combustion gas from diffusing to the stove part, and an exhaust duct connected to the grill is installed toward the exhaust hole opened on the top plate of the table stove. There is known an exhaust structure of a grill cabinet provided with a combustion gas guide member that guides combustion gas without intervention, in which the outer surface of the grill cabinet and the combustion gas guide member have the same distance from the front side to the rear side. .

[0003]

In recent years, the frontage dimension of the grill has tended to be widened. On the other hand, the table stove is usually provided with a pair of left and right stoves. The stove section includes a thermal power adjustment mechanism that controls combustion of the burner above the grill cabinet, and the thermal power regulation mechanism is attached to the side of the grill cabinet. The outer dimensions of the table stove are limited by various standards and cannot be increased easily. Therefore, when the grill cabinet is widened, the distance between the outer surface of the grill cabinet and the heat control mechanism is shortened, and there is a problem that there is no space to install the conventional combustion gas guide member.

In view of the above problems, it is an object of the present invention to provide an exhaust structure for a grill cabinet in which a combustion gas guide member can be attached even if the grill cabinet is widened.

[0005]

In order to solve the above-mentioned problems, the present invention discharges a burner provided in a grill stove to a stove portion of the table stove on an outer surface of a grill stove provided in the table stove. The combustion gas is covered from above to prevent the combustion gas from diffusing to the stove part, and the combustion gas is directed toward the exhaust hole formed on the top plate of the table stove without going through the exhaust duct connected to the grill. In an exhaust structure of a grill cabinet provided with a combustion gas guide member for guiding, a distance between an outer surface of the grill cabinet and the combustion gas guide member in a front portion of the combustion gas guide member is set to be narrower than a distance in other portions. In addition, a bottom plate portion that prevents the combustion gas from leaking downward is formed in the front portion.

Further, the table stove comprises a stove section and a grill section, and the grill section has a grill cabinet having an opening opened by a door on the front side and an exhaust duct on the rear side.
The stove heat regulation mechanism is installed on the side of the grill, and the lower heat burners installed on the left and right sides of the grill have intake ports for taking in secondary air for combustion, and outside the side wall of the grill. In the above, a box-shaped combustion gas guide member for guiding the combustion gas flowing back from the intake port is provided, and the combustion gas guide member has an intake opening at the lower surface and an exhaust opening at the rear of the upper surface. In addition, the front part is formed to be narrower than the rear part, and the bottom plate part is provided on the lower surface of the front part.

The combustion gas guide member does not interfere over the entire front-rear direction with respect to, for example, the heat regulation mechanism of the stove portion, but only at the front side portion. Therefore, it is only the front part that needs to reduce the distance between the outer surface of the grill and the combustion gas guide member. By the way, if the front portion of the combustion gas guide member is brought closer to the outer side surface of the grill cabinet, there is a possibility that a part of the combustion gas overflowing from the grill cabinet will not flow backward but leak from below. Therefore, the bottom plate portion is provided on the front side portion.

When the bottom plate portion completely closes the lower surface of the combustion gas guide member, the suction amount of the secondary air for combustion is reduced. On the other hand, the combustion gas flowing back from the grill chamber collides with the combustion gas guide member and flows downward. Therefore, if the bottom plate portion is formed so as to project from the combustion gas guide member, the flow direction of the combustion gas can be changed by the bottom plate portion from below to the side wall of the grill. If a gap is formed between the tip of the bottom plate portion and the side wall of the grill, secondary combustion air can be sucked through the gap. On the contrary, if the bottom plate portion is projected from the side wall of the grill, a gap is formed between the bottom plate portion and the combustion gas guide member, and the combustion gas that collides with the combustion gas guide member and descends It leaks from the combustion gas guide member through the gap.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, reference numeral 1 denotes a built-in type table cooker, which is installed from a top surface of a countertop CT by a hanging metal fitting 11 located in a window hole W formed in the top surface of the countertop CT. It is suspended. Then, after suspending the table stove 1 in this manner, the top plate 12 is placed on the upper surface to hide the inside of the appliance of the table stove 1. The top plate 12 is provided with an opening 121 larger than an exhaust hole 14 of the grill case 2 described later. The table stove 1 is provided with a stove portion which penetrates the top plate 12 and projects upward, and which is provided with a pair of left and right gas burners 13a in the front portion and one gas burner 13b in the rear portion. The gas cock GC, which is a heating power adjusting mechanism of the stove section 13a provided in the section, is provided so as to sandwich the grill case 2 from the left and right when viewed from the front. Further, in the rear portion of the top plate 12, the exhaust hole 1 facing the exhaust duct 25 for exhausting combustion gas from the grill case 2 installed in the table stove 1.
4 is opened so that it is relatively long in the left-right direction. Reference numeral 15 is a cover plate that covers the exhaust hole 14. A drawer-type door 21 is provided on the front surface of the grill case 2, and the door 21
Is a grill pan 22 with a net 22 on which food is placed.
a is connected. Therefore, when the door 21 is pulled to open the opening 2a on the front surface of the grill case 2, the net 21 is opened together with the door 21.
The cooked food can be placed on the net 22 or the cooked food can be taken out of the grill cabinet 2 by pulling out the cooked food. Further, in the grill case 2, an infrared burner 23 having a flat combustion plate is provided as an upper fire burner on the ceiling surface, and a tubular Bunsen type lower fire burner 24 is provided inwardly of lower portions of both side walls. Bake the top of the placed food with the infrared burner 23,
The lower surface is burned with the lower flame burner 24. On the left and right outer walls 200 of the grill case 2, a window portion 26 for opening air is provided above the lower fire burner 24. Left and right inner side walls 210 are provided inside the left and right outer side walls 200, and an opening 211 facing the lower fire burner 24 and an eaves 212 are formed above the left and right inner side walls 210. Smoke generated from the combustion gas of the infrared burner 23 or the lower fire burner 24 or the cooking product is guided to the exhaust hole 14 by a draft through an exhaust duct 25 extending to the rear of the grill cabinet 2. Then, the inside of the grill cabinet 2 becomes negative pressure, and the window 2
Air in the table stove 1 is sucked into the grill case 2 through the opening 6 and the opening 211. The sucked air is mainly used as secondary air for combustion of the lower fire burner 24.

At the rear of the grill case 2, there is a first fire transfer burner 3 which is a normal fire that extends over one of the lower burners 24 and the infrared burner 23, and a normal fire type which extends over the left and right lower burners 24. Second
A fire transfer burner 4 is provided. The end portions of the fire transfer burners 3 and 4 are inserted into the grill cabinet 2, and the intermediate portions thereof are exposed to the outside space 27 located below the exhaust duct 25. An ignition plug (not shown) and a thermocouple for confirming ignition are attached to the first fire transfer burner 3. When the ignition button (not shown) is operated, the first fire transfer burner 3 is ignited first. A continuous flame is formed over the entire front edge of the first fire transfer burner 3, and this flame ignites both the infrared burner 23 and one lower flame burner 24. Then, the second lower transfer burner 24 is ignited by the transfer of heat to the second lower transfer burner 4, and a continuous flame is formed over the entire front edge of the second lower transfer burner 4, and the second lower transfer burner 2 is formed.
Is ignited. In addition, from the state where both the infrared burner 23 or the lower heat burner 24 is burning, both burners 23.2
Even when switching to a state in which both 4 burn, the two transfer burners 3 perform the transfer ignition.

According to the above construction, while the door 21 is closed and cooking is being performed, the inside of the grill cabinet 2 becomes a negative pressure due to the draft, and the air is sucked into the grill cabinet 2 from the window 26 through the opening 211. However, when the door 21 is opened during cooking, the air suddenly flows into the grill cabinet 2 from the front through the opening 2a on the front surface of the grill cabinet 2. Then, the pressure in the grill cabinet 2 rises, and the combustion gas in the grill cabinet 2 flows backward from the grill cabinet 2 to the stove section through the opening 211 and the window 26. The back-flowing combustion gas flows out into the table stove 1, flows out from the gap between the gas burners 13a and 13b and the top plate, and stirs the flame of the gas burners 13a and 13b to make combustion unstable,
Further, it stays in the stove portion and acts on the combustion air of the gas burners 13a and 13b to make it difficult to ignite, or overheats the inside of the table stove 1. Furthermore, burner burners 3.4
May cause poor combustion.

Therefore, as shown in FIGS. 2 to 4, the combustion gas guide boxes 5, which are combustion gas guide members, are attached to the left and right outer side walls 200 of the grill case 2, respectively, and flow backward from the opening 211 through the window portion 26. The combustion gas is guided to an opening 51 provided at the rear of the stove section, the gas burner 13b, and the fire transfer burners 3 and 4, without passing through the exhaust duct 25 of the grill cabinet 2,
For example, the toner is discharged from the opening 121. The combustion gas guide box 5 is formed by a top plate 5a, side plates 5b, a front plate 5c, and a rear plate 5d into a box shape opened downward. The bottom opening 5e is provided so that secondary combustion air is supplied from the window 26 through the opening 211 to the inside of the grill 2 when the grill door is closed and combustion is being performed. is there. However, since a gas cock GC for adjusting the heating power of the gas burners 13a and 13b is provided on the side of the front of the grill case 2, the front half of the side plate 5b of the combustion gas guide box 5 is replaced with another part in order to avoid the gas cock GC. The outer half walls 200 of the grill cabinet 2 were brought closer than the above portion to narrow the front half of the combustion gas guide box 5. However, when the side plates 5b of the combustion gas guide box 5 are brought closer to both outer walls 200 of the grill case 2 in this way, the passage area of the combustion gas is narrowed, and it is possible to guide all the combustion gas that flows backward from the window 26 to the opening 51. This may not be possible, and there is a risk that a part will overflow from the opening 5e below the combustion gas guide box 5. Therefore, the bottom plate portion 52 is formed in the front half of the combustion gas guide box 5 by bending the lower end of the combustion gas guide box 5.
By providing the bottom plate portion 52 as described above, even if a large amount of the combustion gas flows backward from the window portion 26, the bottom plate portion 52 prevents the combustion gas from overflowing below the combustion gas guide box 5 and the rear opening 51 is provided. Combustion gases can be directed towards.
The bottom plate portion 52 is formed by bending the lower part of the side plate 5b,
In addition, a gap 5f is formed between the bottom plate portion 52 and both outer side walls 200. By configuring in this way,
Even if the combustion gas flowing back from the window portion 26 collides with the inner surface of the side plate 5b and the flow direction changes downward, the leakage of the combustion gas can be prevented at the bottom plate portion 52, and normally the secondary air for combustion is sucked from the gap 5f. You can Further, the front plate 5c is inclined so as to be rearward as it goes downward. Due to this inclination, when the combustion gas that has flowed back from the window portion 26 descends along the inner surface of the front plate 5c, the flow of the combustion gas can be directed rearward and leakage of the combustion gas can be prevented as much as possible. Can be reduced. When the front plate 5c is inclined, the exhaust gas can be prevented from leaking out particularly in the case of the present invention in which the front half of the combustion gas guide box 5 is narrow. In the normal combustion state, the secondary air for combustion of the lower heat burner 24 is
Since the air is sucked into the window 26 through the bottomless portion 53 and the opening 5e in the latter half of the combustion gas guide box 5, the secondary air for combustion does not run short even if the bottom plate 52 is provided.

By the way, a pair of front and rear engaging claws 54 are formed on the combustion gas guide box 5, and the outer wall 20 of the grill cabinet 2 is formed.
Similarly, a pair of front and rear engaging holes 28 are opened at 0, and the engaging claws 54
Is inserted into the engaging hole 28 and the combustion gas guide box 5 is displaced rearward so that the engaging claw 54 is moved to the outer wall 200 of the grill case 2.
The combustion gas guide box 5 is brought into contact with the inner surface of the outer wall 20
It was kept at 0.

In the above embodiment, the top plate 12 is provided with a relatively large opening 121 so that the combustion gas from the exhaust duct 25 and the combustion gas from the combustion gas guide box 5 are both 1
Although the exhaust gas is exhausted from one opening 121 to the outside of the table stove, an exhaust hole different from the exhaust hole for exhausting the combustion gas from the exhaust duct 25 is opened in the top plate 12, and the combustion gas from the combustion gas guide box 5 is combusted. The gas may be led to this other exhaust hole.

Although the built-in type table stove has been described in the above embodiment, the present invention may be applied to a normal table stove placed on the stove stand without being incorporated in the system kitchen. In this case, It may be discharged from an opening formed in the rear wall plate.

By the way, in the above-mentioned embodiment, both the fire transfer burners 3 and 4 are of the normal fire type. However, the flashing ignition burner is ignited only when the infrared burner 23 and the lower fire burner 24 are respectively ignited. You may Further, the present invention can also be applied to the one provided with only the lower flame burner 24 without providing the upper flame burner. In the above embodiment, the door 21 is a drawer type door integrated with the grill pan 22a, but the door 21 may be an openable and closable type that is supported separately from the grill pan 22a and is axially supported by the table stove.

[0017]

As is apparent from the above description, according to the present invention, even if the frontage of the grill is widened and the distance between the stove part and the grill is shortened, the combustion gas flowing back from the inside of the grill can be discharged. Combustion gas can be smoothly discharged from the stove section by guiding it to the exhaust hole.
