Description

  The present invention relates to a grill that cooks a food to be cooked such as fish.

Conventionally, in this type of grill, there is a type in which oil smoke generated from an object to be cooked such as fish is burned out with a heat source for smoke combustion to suppress the emission of oil smoke. For example, as shown in FIG. 5, as a rear exhaust type grill 102 incorporated in a gas stove 101, a flue 105 for introducing oil smoke generated from an object to be cooked F is provided on the rear side of the grill cabinet 120. After burners (heat sources for smoke burning) 161 and 162 are arranged above and below the road 105. Then, by burning the upper and lower afterburners 161 and 162 of the flue 105, the oil smoke flowing into the flue 105 from the inside of the grill 120 is burned out. As a result, the exhaust gas of the grill 102 released to the outside hardly contains oily smoke, and hardly emits oily smoke to the kitchen or the like where the grille 102 is installed.
Japanese Patent No. 2757483

By the way, in the conventional grill 102, the afterburners 161 and 162 are installed above and below the flue 105 in order to increase the smoke removal rate, and therefore the exhaust gas or hot air of the upper and lower afterburners 161 and 162 interfere with each other. The flow of oil smoke is obstructed and the exhaust resistance in the flue 105 is increased. Then, a part of the oil smoke in the grill cabinet 120 does not pass through the flue 105 and goes out to other places, for example, through the gap of the grill door 104, so that it cannot be smoked.
There are also grills that have an afterburner only at the top of the flue. In this case, the exhaust gas and hot air from the afterburner flow along the upper side of the flue. It becomes difficult to burn out the oil smoke.
The above problems also occur in a grill using a heater or the like as a heat source for smoke burning.

  The present invention has been made in view of the above circumstances, and provides a grill in which exhaust is smoothly performed by suppressing the exhaust resistance without lowering the smoke removal performance by reviewing the arrangement of the heat source for smoke burning. This is the issue.

The grill according to the present invention is
A grill equipped with a heat source for smoke burning to suppress the emission of oil smoke,
A grill cabinet that arranges a cooking heat source and cooks the food to be cooked,
A flue that is provided on the rear side of the grill cabinet and introduces oil smoke generated from the food in the grill cabinet;
An exhaust pipe standing upright at the downstream position of the flue and exhausting outside,
The heat source for smoke burning is provided only at the lower part of the flue with the heating surface facing upward ,
A shielding part is suspended from the upper part near the entrance of the flue, and the heat source for the smoke burning is disposed behind the shielding part and directly under the exhaust pipe,
A lath mesh is installed so that at least a part of the heat source for the smoke burning is opposed to the heat source for the smoke burning,
A catalyst filter is installed in the vicinity of the exit of the flue or in the exhaust pipe and above the lath mesh .
According to the grill, since the heat source for smoke burning is provided only at the lower part of the flue, the flow of exhaust gas and hot air from the heat source for smoke burning is directed to the exhaust pipe downstream of the flue. Thereby, the draft force in an exhaust pipe rises, the oil smoke which flowed into the flue from the grill warehouse can be directed to the exhaust pipe side, and the increase in exhaust resistance can be suppressed .

In addition , because the smoke burning heat source is located directly below the exhaust pipe, the exhaust gas and hot air from the smoke burning heat source do not flow backward in the flue (flow toward the grill box), and are directly inside the exhaust pipe. The draft effect in the exhaust stack is increased. Therefore, the exhaust resistance in the flue is not increased by the combustion of the heat source for smoke burning, and the flow of oil smoke from the inside of the grill to the flue can be performed more smoothly .

Furthermore, vertically shielding portion from the top near the inlet of the upper Kikemurido, by disposing the heat source for the smoke sintered on the far side from the shield section, flue, the upper in the vicinity of the inlet by the shield section Since it is enclosed, the exhaust gas and hot air of the heat source for smoke burning flow toward the exhaust pipe at the downstream position of the flue without going to the grill box side, and the draft force in the exhaust pipe is increased. Therefore, the exhaust resistance in the flue is not increased by the combustion of the heat source for smoke burning, and the flow of oil smoke from the inside of the grill to the flue can be performed smoothly.
On the other hand, since the shielding portion in the vicinity of the entrance of the flue is located, oily smoke flows upward in the grill chamber and flows is flowed downward hits the shield portion from the underside of the flue to the chimney. Then, oily smoke flowing into the exhaust pipe is exposed to the combustion of much arranged smoke sintered heat source beneath the stack while rising the exhaust pipe, is burnt off sufficiently by smokeless, is odorless .

In addition, a lath mesh is installed at a position above the smoke burning heat source so that at least a part thereof faces the smoke burning heat source, so that the lath mesh faces the heat source for the smoke burning and is heated. Therefore , its oil smoke treatment performance is demonstrated at an early stage. Therefore, even if not all of the smoke is completely processed by the smoke burning heat source, the remaining smoke is burned out by passing through the heated lath mesh, and smokeless and bromide-free.

In the grill, the remaining oil smoke that has not been burned out in the lath mesh by installing the catalyst filter in the vicinity of the exit of the flue or in the exhaust pipe and above the lath mesh, When passing near the exit of the road or through the exhaust stack, the catalyst filter is smoke-free and bromide-free.

As described above, according to the present invention, the smoke with the draft force of the exhaust pipe by hot air and exhaust gas smoke sintered heat source provided only at the bottom of the flue above Ri, the oily smoke flowing into the flue are burned off Head to the exhaust stack downstream of the road . The oil smoke that has not been treated with the heat source for smoke burning is burned off with a lath mesh, and the remaining oil smoke that has not been treated with the lath mesh is smokeless and non-brominated by the catalyst filter. As a result, high smoke removal performance is exhibited, and clogging of the catalyst filter hardly occurs. Therefore , it is possible to smoothly exhaust the exhaust gas while suppressing the exhaust resistance in the flue without reducing the smoke removal performance.

( Prerequisite technology 1 )
First, the base technology 1 of the present invention will be described.
As shown in FIG. 1, a grill 2 according to the premise technique 1 of the present invention is a rear exhaust type grill 2 incorporated in a gas stove 1, and has a substantially rectangular shape for heating and cooking an object to be cooked F such as fish. The grill cabinet 20 is disposed in the stove body. The front surface of the grill cabinet 20 is opened, and a grill door 4 that can be freely opened and closed is attached to the opening. A grill pan 32 having a grill 31 on which the food F is placed is housed in the grill cabinet 20, and when the food F is to be cooked, the grill door 4 is opened and the grill pan 32 is pulled out for baking. The cooking object F is placed on the net 31 and the grill pan 32 is returned to the grill cabinet 20 again.

  An upper fire burner (cooking heat source) 21 is provided in the upper part of the grill cabinet 20 above the grill net 31, and the left and right side walls of the grill cabinet 20 below the grill net 31 are lowered in the front-rear direction. A burner (heat source for cooking) 22 is provided. The upper fire burner 21 is composed of a surface combustion type burner having a ceramic combustion plate in which a large number of flame holes are formed, and is arranged on the upper portion of the grill cabinet 20 with the combustion plate directed downward. The lower fire burner 22 is composed of a Bunsen burner, and is disposed on the left and right side walls in a posture in which a plurality of flame holes are directed toward the center of the grill cabinet 20. When the upper fire burner 21 is burned, the combustion plate becomes red hot, and the food F placed on the grill 31 is heated from above by the radiant heat from the combustion plate, and when the lower fire burner 22 is burned, flame is generated. The cooking object F that extends to the center of the grill cabinet 20 and is placed on the grill 31 is heated from below by this flame and the hot air of the flame.

  On the rear side of the grill 20, there is provided a flue 5 for introducing oil smoke generated from the cooking object F being cooked, exhaust gas of the upper fire burner 21 and the lower fire burner 22, and the upper part 51 of the flue 5. On the far side (downstream position), an exhaust cylinder 50 is provided upright to reach the exhaust port 12 provided in the top plate 11 of the gas stove 1. The upper and lower widths of the flue 5 are provided so that the height of the upper part 51 is the same position as the upper part of the grill warehouse 20 and the height of the lower part 52 is located above the grill net 31 arranged in the grill warehouse 20. However, it may be provided so as to be located below the grill 31. Moreover, the horizontal width of the flue 5 may be provided so as to be located inside the left and right walls of the grill cabinet 20, or may be provided so as to match the left and right walls of the grill cabinet 20 (not shown). . The left and right walls of the flue 5 may be formed in a tapered shape so as to gradually narrow from the entrance to the middle of the depth or from the back wall.

  In the lower part 52 of the flue 5, an after burner (smoke burning heat source) 6 is installed in a posture in which the combustion surface (heating surface) faces the upper exhaust tube 50 with the combustion surface (heating surface) positioned directly below the exhaust tube 50. ing. The afterburner 6 is composed of a surface combustion type burner similar to the upper fire burner 21 and burns off the oil smoke generated from the food F to be smokeless and non-bromide. Note that the afterburner 6 can also be constituted by a Bunsen burner. Further, the exhaust pipe 50 is provided with a catalyst filter 7 for further performing smokeless and non-bromide treatment of the oil smoke.

  According to the grill 2, when the inside of the grill cabinet 20 is heated by the combustion of the upper fire burner 21 and the lower fire burner 22, oil smoke generated from the cooking object F due to the natural draft in the exhaust pipe 50 flows to the flue 5. And flowed in. At this time, since the afterburner 6 is provided only in the lower portion 52 of the flue 5, the flow of exhaust gas and hot air from the afterburner 6 goes to the upper exhaust pipe 50 which is the downstream position of the flue 5. Thereby, the draft in the exhaust pipe 50 is improved. Therefore, it is possible to push up the oil smoke flowing into the flue 5 from the grill warehouse 20 by the exhaust gas and hot air of the after burner 6 and to direct the smoke toward the upper exhaust cylinder 50, and the combustion of the after burner 6 etc. An increase in exhaust resistance can be suppressed.

In particular, in the grill 2 , the afterburner 6 is located directly below the exhaust pipe 50, so that the exhaust gas and hot air of the afterburner 6 do not flow backward in the flue 5 (flow toward the grill box 20), The air flows into the exhaust pipe 50 directly above, and the draft effect in the exhaust pipe 50 is increased. Therefore, the exhaust resistance in the flue 5 is not increased by the combustion of the afterburner 6, and the flow of oil smoke from the inside of the grill warehouse 20 to the flue 5 can be performed more smoothly. In addition, in the exhaust cylinder 50, in addition to the natural draft, a draft force due to the combustion of the afterburner 6 acts. There is no increase in resistance.

  By the way, when the exhaust resistance of the grill increases, the entry of secondary air becomes worse, for example, the combustion distribution of the Bunsen type lower burner becomes uneven, and heat becomes difficult to reach the center of the grill cabinet, so Baking can be bad. On the other hand, in the grill 2, even if the after burner 6 is installed, the exhaust resistance is not increased, so that the secondary air is smoothly introduced and the combustion distribution of the lower fire burner 22 is made uniform. The baking unevenness of the cooking object F is not caused.

  On the other hand, since the afterburner 6 is located directly below the exhaust pipe 50, the oil smoke is exposed to the combustion of the afterburner 6 as long as it rises up the exhaust pipe 50, and the contact time with the combustion of the afterburner 6 Becomes longer. Accordingly, the afterburner 6 can sufficiently burn out the oily smoke so that it is smokeless and non-brominated.

  Further, since the catalyst filter 7 provided in the exhaust pipe 50 is directly heated by the afterburner 6 so as to face the afterburner 6, the catalyst temperature rises quickly and sufficient catalyst performance can be activated early. . Therefore, even if not all of the smoke is completely treated by the afterburner 6, the remaining smoke is treated smokeless and non-brominated by the catalytic filter 7 so that almost no smoke is emitted from the exhaust port 12 to the outside. be able to.

As described above, according to the grill 2 according to the base technology 1, exhaust is smoothly performed while suppressing the exhaust resistance in the flue 5 without reducing the smoke removal performance. Further, since the exhaust resistance of the grill 2 is not increased, the secondary air can be smoothly introduced, the combustion distribution of the lower fire burner 22 can be performed uniformly, and the cooking object F can be heated uniformly. it can.

( Prerequisite technology 2 )
Next, the base technology 2 of the present invention will be described.
As shown in FIG. 2, the grill 2 </ b> A according to the base technology 2 of the present invention has a flue 5 formed in an upward slope toward the rear, and the afterburner 6 is burned near the entrance of the lower part 52 of the flue 5. It is installed with its surface (heating surface) facing almost directly above. The upper part 51 of the flue 5 is formed in an upward slope toward the rear by being continuously provided from the lower end of the rear wall that hangs down directly from the upper part of the grill cabinet 20. The rear wall extends on the rear side of the upper fire burner 21 so that the lower end of the rear wall is positioned below the upper fire burner 21, so that the oil smoke generated from the food F and the exhaust gas of the upper fire burner 21 are moved downward. It also has a function as a shielding part 9 that faces the head. In addition, although the lower part 52 of the flue 5 is formed in the upward gradient toward back like the upper part 51, this lower part 52 may be formed horizontally.

Further, on the upper side in the flue 5, an afterburner 6 and a lath mesh 8 with a part thereof facing each other are installed in a horizontal posture from the entrance of the flue 5 to the back wall. A catalyst filter 7 is installed at the outlet of the upper part 51 side of the flue 5 located above the lath mesh 8. Further, an exhaust pipe 50 is erected at the exit (downstream position) of the flue 5. Note that the catalyst filter 7 may be installed in the exhaust pipe 50 in the same manner as the base technology 1 described above .

  According to this grill 2A, the flue 5 is formed in an upward slope, and the afterburner 6 is provided only in the lower part 52 of the flue 5, so that the exhaust gas and hot air of the afterburner 6 released upward are It is promoted to flow into the exhaust tube 50. Thereby, the draft force in the exhaust pipe 50 is improved. Therefore, the exhaust resistance in the flue 5 is not increased by the combustion of the afterburner 6, and the increase in the exhaust resistance due to the installation of the catalyst filter 7 can be suppressed.

  Further, the lath mesh 8 is arranged in a certain direction so as to coincide with the flow direction of exhaust (oil smoke and exhaust gas) toward the exit of the flue 5, so this lath mesh 8 is installed. As a result, the exhaust resistance is not increased. Therefore, the flow of the oil smoke from the grill warehouse 20 to the flue 5 can be performed smoothly.

  On the other hand, since the afterburner 6 is installed near the entrance of the lower part 52 of the flue 5, most of the oil smoke flowing into the flue 5 from the grill 20 is burned out by the afterburner 6. Smokeless and brominated. That is, in this grill 2, the shielding part 9 is formed on the upper side of the entrance of the flue 5, so that the oil smoke flowing above the inside of the grill cabinet 20 hits the shielding part 9, and the flow velocity is reduced so that much of it is increased. It is burned out by the fire burner 21. In addition, the oil smoke flowing above the inside of the grill cabinet 20 hits the shielding portion 9 and flows downward, and flows from the lower side of the flue 5. Therefore, the amount of oil smoke near the entrance of the flue 5 is relatively small in the upper half of the flue 5 and tends to be large in the lower half. Most of the oil smoke flowing into the lower half of the entrance of the flue 5 is burned out by the afterburner 6 disposed in the vicinity of the entrance of the lower part 52 of the flue 5.

  Further, the oil smoke passing through the upper half of the flue 5 and the oil smoke that has not been treated by the afterburner 6 are burned out by the lath mesh 8 disposed on the upper side in the flue 5. In particular, a part of the lath mesh 8 is heated so as to face the afterburner 6 and is installed on the upper side of the inclined flue 5 in a horizontal posture from the entrance of the flue 5 to the back wall. The oil smoke passing through the lath mesh 8 can be almost burned out.

  Furthermore, even if the afterburner 6 and the lath mesh 8 are not completely treated with the oil smoke, the remaining oil smoke is smokeless and non-bromide treated with the catalyst filter 7 located above the lath mesh 8, and from the exhaust port 12. Almost no smoke can be emitted to the outside.

As described above, the grill 2A according to the base technology 2 can also smoothly perform exhaust by suppressing the exhaust resistance in the flue 5 without reducing the smoke removal performance. Further, since the exhaust resistance of the grill 2A is not increased, the secondary air can be smoothly introduced, the combustion distribution of the lower fire burner 22 can be performed uniformly, and the cooking object F can be heated uniformly. it can.

In the base technology 2, the afterburner 6 is installed so that the combustion surface faces almost directly above, but the combustion surface is arranged in the direction of the outlet of the flue 5 (downstream) to which the lower end of the exhaust pipe 50 is connected. It may be installed tilted so as to face (position). In this case, the exhaust gas and hot air of the afterburner 6 are further promoted so as to flow toward the exhaust tube 50 side, and the exhaust resistance in the flue 5 can be further suppressed, and the hot air and flue of the afterburner 6 are further reduced. The contact time with the oil smoke passing through 5 can be lengthened to further improve the smoke removal rate.
Other contents are the same as those of the base technology 1 described above .

(In the form state of implementation)
Next, an embodiment of the present invention will be described.
As shown in FIG. 3, the grill 2 </ b > B according to the embodiment of the present invention is provided with a flue 5 that is recessed rearward on the rear side of the grill 20, and the inside of the grill 20 before the entrance of the flue 5. A shielding plate (shielding portion) 90 is suspended from the upper part of the slag, and the upper half of the entrance of the flue 5 is blocked. An exhaust pipe 50 is erected on the upper part (downstream position) of the flue 5. In the lower part 52 of the flue 5 at the back of the shielding plate 9, the after burner 6 is installed in a posture in which the combustion surface (heating surface) faces the upper exhaust tube 50 with the combustion surface (heating surface) facing the upper exhaust tube 50. Yes. Above the after burner 6, a lath mesh 8 is installed from the lower end of the shielding plate 90 to the inner wall of the flue 5. Further, a catalyst filter 7 is installed above the lath mesh 8 in the vicinity of the connection portion with the exhaust pipe 50 at the outlet of the flue 5. The lath mesh 8 can be arranged so that the direction of the mesh is aligned in a certain direction so as to match the flow direction of the exhaust gas toward the outlet of the flue 5 (see FIG. 2). ).

According to this grill 2B, since the lower end of the exhaust pipe 50 is surrounded by the shielding plate 90, the exhaust gas and hot air of the afterburner 6 flow into the exhaust pipe 50 in the same manner as in the base technology 1 described above. A draft force generated by the combustion of the burner 6 can be applied to the exhaust pipe 50. Thereby, the draft force in the exhaust pipe 50 is increased. Therefore, the exhaust resistance in the flue 5 is not increased by the combustion of the afterburner 6, and the flow of oil smoke from the grill warehouse 20 to the flue 5 can be performed smoothly.

On the other hand, by disposing the shielding plate 90 substantially at the upper half of the entrance of the flue 5, the oil smoke flowing above the inside of the grill cabinet 20 hits the shielding plate 90 and the flow velocity is reduced, as in the above-described prerequisite technology 2. Thus, the time to be exposed to the upper fire burner 21 becomes longer, and most of it is burned out by the upper fire burner 21. In addition, the oil smoke flowing above the inside of the grill cabinet 20 hits the shielding portion 90 and flows downward, and flows into the lower side of the flue 5. The oil smoke flowing in from the lower side of the flue 5 is burned out by the afterburner 6 disposed on substantially the entire lower part 52 of the flue 5.

  Further, since the afterburner 6 is located directly under the exhaust pipe 50, the oil smoke flows into the flue 5 and rises in the exhaust pipe 50, and is therefore exposed to the combustion of the afterburner 6 so that the afterburner 6 The contact time with combustion of the burner 6 becomes long. Therefore, the afterburner 6 installed only in the lower part 52 of the flue 5 can sufficiently burn out the oily smoke so as to be smokeless and non-bromide.

  Further, since the lath mesh 8 and the catalyst filter 7 are sequentially arranged above the after burner 6 so as to face the after burner 6, the lath mesh 8 and the catalyst filter 7 are heated by the after burner 6, respectively. The oil smoke treatment performance is demonstrated at an early stage. Therefore, even if all the smoke is not completely treated by the afterburner 6, the remaining smoke is burned out by passing through the heated lath mesh 8, and has also passed through this lath mesh 8. The remaining oil smoke passes through the catalyst filter 7 and is smokeless and non-bromide-treated, so that almost no oil smoke can be emitted from the exhaust port 12 to the outside.

As described above, according to the grille 2B according to the shape condition of the present invention, to burn off the soot that has not been treated with afterburner 6 Las th network 8, remaining that has not been treated yet in that lath-th network 8 Since the oil smoke is configured to be smokeless and non-brominated by the catalyst filter 7, high smoke removal performance is exhibited. Further, by adopting the above-described configuration, it is difficult to cause clogging of the catalyst filter 7, so that an increase in exhaust resistance is also suppressed. Therefore, exhaust is smoothly performed while suppressing exhaust resistance in the flue 5 without deteriorating the smoke removal performance. Further, since the exhaust resistance of the grill 2B is not increased, the secondary air is smoothly introduced, the combustion distribution of the lower fire burner 22 is uniformly performed, and the cooking object F can be heated uniformly. it can.
Other contents are the same as those of the base technology 1 described above .

(Reference example)
As shown in FIG. 4, this grill 2 </ b> C has a grill cabinet 20 in which a grill 31 on which an object to be cooked F is placed is arranged, and an upper fire burner 21 as a heat source for cooking above and below the grill cabinet 20. And a lower fire burner 22 are arranged. A flue 5 is disposed on the rear side of the grill cabinet 20, and an exhaust pipe 50 is erected on the upper portion (downstream position) of the flue 5. A shielding plate (shielding portion) 90 is suspended from the upper part of the grill cabinet 20 so as to block the upper half of the entrance of the flue 5. A lath mesh 8 is installed from the lower end of the shielding plate 90 to the inner wall of the flue 5, and the catalyst filter 7 is installed above the lath mesh 8. A heater H is installed between the lath mesh 8 and the catalyst filter 7 to heat the lath mesh 8 and the catalyst filter 7 simultaneously.

That is, this grill 2 Oite the form status of the above-described embodiment, without installing the afterburner 6, in which to install the heater H between the lath first network 8 and the catalyst filter 7. The heater H simultaneously heats the upper catalyst filter 7 and the lower lath mesh 8 to exhibit each of the sufficient oil smoke treatment performance at an early stage.

  According to the grill 2C, since the afterburner 6 is not provided, the exhaust resistance in the flue 5 is not increased by the combustion of the afterburner 6 in the first place. In the grill 2, the heater H is disposed at a position below the exhaust cylinder 50, so that the draft force generated by the heating of the heater H can be applied to the exhaust cylinder 50. Therefore, the flow of the oil smoke from the grill warehouse 20 to the flue 5 can be performed smoothly.

Further, the oil smoke introduced into the flue 5 is burned off by passing through the lath mesh 8 heated by the heater H, and the remaining oil smoke passing through the lath mesh 8 passes through the catalyst filter 7. As a result, almost no smoke or bromide treatment is performed, and almost no oil smoke is emitted from the exhaust port 12 to the outside.
Therefore, even with the grill 2C according to this reference example, the exhaust resistance can be suppressed smoothly in the flue 5 without reducing the smoke removal performance.
Other content, except for the afterburner 6, is on purpose similar form described above.

Incidentally, the grill according to the present invention is not limited to the form of implementation described above, it is possible to apply various design changes.
For example, the grill cabinet 20 includes the upper fire burner 21 and the lower fire burner 22, but only one of them may be provided.
Further, the upper fire burner 21, the lower fire burner 22, and the after burner 6 may be constituted by an electric heater or the like.
In addition, the grills 2, 2A, 2B, and 2C have been incorporated into the gas stove 1. However, the grills 2, 2A, 2B, and 2C may be incorporated into various heating cookers such as an IH stove, and are applicable to independently installed grills. May be.
