Description

  The present invention relates to a grill provided with a flue that guides combustion exhaust gas of a burner provided on a ceiling portion of a grill warehouse to an exhaust port at the upper rear side.

  Conventionally, in this type of grill (Patent Document 1), a partition plate that extends upward from the rear wall portion of the grill cabinet at the entrance of the flue and a guide that extends downward from the ceiling portion of the flue facing the rear of the partition plate. By providing the plate, the flame is prevented from overflowing from the exhaust port through the flue when ignition occurs in the grill. In addition, the partition plate at the flue entrance is provided with a plurality of vent holes in the part facing the guide plate, so that the combustion exhaust gas in the grill can be smoked not only from the communication port above the partition plate but also from the vent hole of the partition plate. It flows into the road and prevents the combustion exhaust gas from staying in the upper part of the grill cabinet, so that the burner does not fail to burn.

JP 2009-112363 A

  However, in the conventional grill, when the combustion exhaust gas is taken into the flue from the grill warehouse, the inflow from the vent hole has a larger passage resistance than the inflow from the communication port, so the flow of the combustion exhaust gas is obstructed and enters the flue. The combustion exhaust gas was difficult to be taken in efficiently. In addition, it is difficult for the flue gas to escape smoothly in the flue due to the guide plate. Therefore, combustion exhaust gas from the inside of the grill is insufficient, and it is difficult to sufficiently supply secondary air to the burner, and improvement of burner combustibility has not been sufficient.

  In addition, when a fluid such as spilled water enters the flue from the exhaust port, the spilled water is clogged by the partition plate and accumulated in the flue. Cleaning the flue is not easy. For example, if boiled spills accumulate near the temperature sensor installed in the flue, the detection accuracy of the sensor may be reduced.

  The present invention has been made in view of the above circumstances, and combustion exhaust gas is efficiently taken into the flue from the grill warehouse to improve the burnability of the burner, and a fluid such as spilled infiltrated into the flue from the exhaust port is provided. An object of the present invention is to provide a grill that is discharged from the flue and can be easily cleaned.

The grill according to the present invention is
A grill chamber for storing the food to be cooked, a burner provided on the ceiling of the grill cabinet for heating the food to be cooked, and a burner exhaust gas communicating with the rear upper exhaust port from the rear wall of the grill cabinet A grill with a flue leading to
At the entrance of the flue, a rectifying plate that extends in front of the grill cabinet and divides the space up and down is provided at a position close to the bottom of the flue so that the flue gas is directed to the upper side of the entrance of the flue ,
At the entrance of the flue, a plate wall is arranged in the lower part of the current plate,
The plate wall portion is provided with an opening for discharging a fluid such as spilled infiltrated from the exhaust port into the grill cabinet .

  From the above configuration, the combustion exhaust gas from the burner at the ceiling of the grill cabinet is discharged from the lower side of the entrance of the flue and the grill below the flue from which fluids such as spillage that has entered from the exhaust port are discharged by the baffle plate A flow that flows into the flue from the upper side of the entrance of the flue is formed so as not to go to the rear wall of the warehouse. Therefore, the combustion exhaust gas from the burner is smoothly taken into the flue without causing exhaust resistance or turbulent flow around the entrance of the flue, being efficiently guided to the exhaust port, and staying in the grill warehouse. It is prevented. Therefore, the combustion secondary air is sufficiently supplied to the burner, and the burnability of the burner can be improved.

In addition, a fluid such as spilled water that has entered the flue from the exhaust port can be discharged from the entrance of the flue on the lower side of the rectifying plate into the grill cabinet, and staying in the flue is prevented. Therefore, the grill can be easily and easily cleaned.
In addition, a plate wall portion is disposed at the lower portion of the current plate at the entrance of the flue, and an opening for discharging a fluid such as spilled material that has entered from the exhaust port into the grill chamber. Since spilled from the exhaust port is discharged into the grill through the opening, it is prevented from accumulating in the flue.
By the way, the combustion exhaust gas in the grill can also flow into the flue from the opening. In this case, the inflow from the opening of the flue gas has a larger passage resistance than the inflow from the upper side of the flue inlet, so that the flow of the flue gas is obstructed and the turbulent flow around the flue inlet For example, combustion exhaust gas may not be efficiently taken into the flue.
On the other hand, according to the above configuration, the rectifying plate is disposed at the upper part of the opening provided in the plate wall, and the rectifying plate emits the combustion exhaust gas from the burner at the ceiling of the grill cabinet toward the upper side of the inlet of the flue. Therefore, combustion exhaust gas is prevented from flowing into the opening side below the rectifying plate, and inflow of combustion exhaust gas from the opening is prevented. Therefore, the flue gas flows into the flue from the opening so that the exhaust resistance is increased and the flow of the flue gas flowing into the flue from the inside of the grill is not obstructed, and the flue gas is smoothly flowed into the flue. It can be taken in and efficiently led to the exhaust port.

It is desirable that the rectifying plate is inclined downward toward the front of the grill box.
Thereby, the flow which the combustion exhaust gas which generate | occur | produced from the burner of the ceiling part of a grill warehouse goes to the upper part side of the entrance of a flue can further be accelerated | stimulated. In addition, fluids such as boiled spills discharged from the flue entrance into the grille are directed downward in the grille when they exit the flue entrance and collected in a grill pan placed at the bottom of the grille. It can be made easy.

In addition, at the entrance of the flue, a shielding plate for preventing flame intrusion is arranged above the current plate,
It is desirable that a combustion exhaust gas intake is formed between the upper end of the shielding plate and the ceiling of the grill cabinet.
As a result, when ignition occurs in the grill, the shielding plate can prevent the flame from entering the flue and prevent the flame from overflowing from the exhaust port. Further, the combustion exhaust gas in the grill can be directed upward by the shielding plate, and can be caused to flow into the flue from an intake port formed at a position above the entrance of the flue.

Further, it is desirable that the baffle plate is inclined downward and forwardly toward the front of the grill cabinet, and the front end height is set to be equal to or lower than the lower end height of the opening.
Thereby, while the combustion exhaust gas in a grill warehouse promotes the flow which goes to the upper part side of the entrance of a flue, it can prevent more reliably that it wraps around the lower side of a baffle plate, and flows into an opening part.

Furthermore, a space part is provided at the lowermost part of the rear wall part of the grill cabinet so that a part of the grill dish is arranged further rearward than the rear wall part, and the grill dish is also arranged below the wall surface of the rear wall part. It is desirable to do.
As a result, fluid such as spilled oil that enters from the exhaust port and is discharged from the entrance of the flue into the grill can be reliably recovered in the grill pan without contaminating the bottom of the grill. Therefore, dirt in the grill can be suppressed, and cleaning can be performed easily and easily.

  According to the grill of the present invention, by providing a baffle plate at the inlet of the flue, combustion exhaust gas is efficiently taken into the flue from the grill warehouse, and the secondary air for combustion is sufficiently supplied to the burner, so that the burner Combustibility can be improved. In addition, fluids such as spills that have entered the flue from the exhaust port can be discharged from the flue entrance under the baffle plate into the grill cabinet without being caught in the flue, making cleaning the grill easy and easy. It can be carried out.

It is side surface sectional drawing which shows the structure of the grill by embodiment. It is front sectional drawing which shows the structure of the grill by embodiment. It is side surface sectional drawing which shows the modification of the grill of embodiment.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to FIGS. 1 and 2, a grill 1 according to the embodiment is a rear exhaust-type grill incorporated in a gas stove (not shown), and a grill 10 for storing an object to be cooked such as fish (not shown). And a burner 2 for heating the object to be cooked, and a flue 3 for guiding the combustion exhaust gas generated from the burner 2 to the exhaust port 31 at the rear upper part. A grill pan 15 that supports a grill 14 on which the object to be cooked is placed is housed in the grill cabinet 10. The grill pan 15 is detachably connected to a grill door 13 that opens and closes the front opening of the grill cabinet 10, and is pulled out from the front of the grill cabinet 10 by pulling the grill door 13 forward.

  The burner 2 is provided in the ceiling part 11 of the grill cabinet 10 and heats the food to be cooked placed on the grill 14. The burner 2 is composed of a burner in which a lower plate 21 having a large number of flame holes is mounted on the lower surface. A plurality of air holes 16 for taking in the secondary air for combustion of the burner 2 are formed in the left and right side walls of the grill cabinet 10. In the burner 2, the air-fuel mixture (mixed gas of fuel gas and primary air) ejected from the flame holes of the lower plate 21 is supplied with the secondary air for combustion from the air holes 16 and burns completely. The combustion exhaust gas generated by the combustion of the air-fuel mixture in the burner 2 is discharged to the outside from the rear upper exhaust port 31 through the flue 3 provided in the rear wall portion 12 of the grill warehouse 10.

  The flue 3 is provided so as to be bent in a substantially square shape from the rear wall portion 12 of the grill 10 and communicate with the exhaust port 31 in the upper rear portion. The inlet 32 of the flue 3 is provided in the upper part of the rear wall part 12, and the height of the lower end of the inlet 32 is located above the grill 14. Therefore, the inlet 32 of the flue 3 is disposed above the food to be cooked on the grill pan 15 and the grill 14 which are the main ignition source positions in the grill 10.

  A bottom surface 33 of the flue 3 is inclined upward and rearward from the inlet 32 of the flue 3. Accordingly, a fluid such as spilled water (hereinafter simply referred to as “simmered”) that has entered from the exhaust port 31 flows through the inclined bottom surface 33 of the flue 3 and is guided to the inlet 32 of the flue 3. . The bottom surface 33 of the flue 3 is provided with a temperature sensor 4 for detecting the temperature in the grill 10 at a substantially central position of the inclined bottom surface 33. The temperature sensor 4 is surrounded by a sensor cover 41. The sensor cover 41 has a window portion 41a opened at a lower portion of the front surface facing the front of the grill cabinet 10, and a front surface, an upper surface, left and right side surfaces, and a rear surface above the window portion 41a are closed. Accordingly, when the spilled portion enters from the exhaust port 31, the sensor cover 41 prevents the spilled portion from adhering to the temperature sensor 4 and prevents the detection accuracy of the temperature sensor 4 from being lowered. Further, since the hot air in the grill cabinet 10 reaches the temperature sensor 4 through the window 41a on the front surface of the sensor cover 41, the temperature sensor 4 can accurately detect the temperature in the grill cabinet 10. When the temperature detected by the temperature sensor 4 rises abnormally, the burner 2 is extinguished.

  The entrance 32 of the flue 3 is provided with a shielding plate 5 that extends upward from the bottom surface 33 of the flue 3 and is disposed in the lower portion of the entrance 32 of the flue 3. The shielding plate 5 is formed across the width of the flue 3. The shielding plate 5 can be integrally formed by bending the component plate of the bottom surface 33 of the flue 3 upward, but may be formed by a plate member different from the component plate of the bottom surface 33 of the flue 3. Then, a horizontally long take in which the combustion exhaust gas from the burner 2 is taken into the flue 3 by communicating the inside of the grill compartment 10 and the flue 3 between the upper edge of the shielding plate 5 and the ceiling portion 11 of the grill compartment 10. A slot 51 is formed.

  Here, when cooking the food to be cooked, the fat that oozes out from the food to be cooked and accumulates on the grill plate 15, the fat to be cooked, and the fat scattered from the food to be cooked may ignite. There is a risk that a flame may enter the flue 3 and overflow from the exhaust port 31. The flame generated in the grill 10 spreads from a relatively lower position in the grill 10 where the grill pan 15 and the food to be cooked are arranged.

  Therefore, in the present embodiment, the inlet 32 of the flue 3 is provided at a higher position away from the grill pan 15 and the grill 14 at the bottom of the grill cabinet 10, and further at the lower portion of the inlet 32 of the flue 3. A shielding plate 5 is provided. Thereby, even if the flame generated in the grill 10 spreads to the inlet 32 of the flue 3, it is blocked by the shielding plate 5 and the flame is prevented from entering the flue 3. Therefore, the flame overflow from the exhaust port 31 is prevented.

  By the way, if the lower part of the inlet 32 of the flue 3 is completely blocked by the shielding plate 5, the spillage that has entered from the exhaust port 31 stays in the flue 3, for example, the spillage near the temperature sensor 4. When it accumulates, there exists a possibility that the detection accuracy of the temperature sensor 4 may fall. Moreover, cleaning inside the flue 3 is not easy.

  Therefore, in the present embodiment, an opening 52 for discharging the spillage that has entered the flue 3 from the exhaust port 31 into the grill warehouse 10 is provided in the plate wall portion below the shielding plate 5. The lower end of the opening 52 coincides with the bottom surface 33 of the flue 3. Two openings 52 are provided at the left and right positions, respectively, with the central portion facing the temperature sensor 4 removed, but may be one opening 52 that also penetrates the central portion. Further, the bottom surface 33 of the flue 3 is inclined upward and rearward toward the exhaust port 31. Thereby, the spilled water that has entered from the exhaust port 31 flows toward the grill 10 through the bottom surface 33 of the flue 3, is divided into left and right by the sensor cover 41, and passes through the left and right openings 52 of the shielding plate 5. Then, it is discharged into the grill cabinet 10. Therefore, the spillage does not accumulate in the flue 3 and can be discharged into the grill 10, dirt in the flue 3 can be suppressed, and the grill 1 can be easily and easily cleaned.

  In addition, only with the configuration of the shielding plate 5 and the opening 52 described above, the combustion exhaust gas of the burner 2 installed on the ceiling portion 11 of the grill cabinet 10 is not only the wide intake port 51 on the shielding plate 5 but also the shielding plate. 5 may also flow into the flue 3 from a narrow opening 52 provided in the lower part of 5. When the combustion exhaust gas flows from the inside of the grill 10 into the inlet 32 of the flue 3, the inflow from the narrow opening 52 has a larger passage resistance than the inflow from the wide intake port 51. As a result, the flue gas flows into the flue 3 as a result of obstruction of the flow of the flue gas flowing into the inlet 32 and the turbulent flow around the inlet 32 of the flue 3 due to the two flows having different passage resistances. There is a risk that it will not be taken in well.

  Thus, in the present embodiment, the flue 3 approaches the bottom 32 of the flue 3 above the opening 52 so that the flue gas is directed to the upper side of the flue 3 inlet 32 at the inlet 32 of the flue 3. At the position, a rectifying plate 7 is provided that extends forward of the grill 10 and divides the space vertically. The rectifying plate 7 can be integrally formed by extending the component plate of the rear wall portion 12 of the grill cabinet 10 upward and bending it forward, but is different from the component plate of the rear wall portion 12 of the grill cabinet 10. You may form with a plate member. When the rectifying plate 7 is extended from the rear wall 12, an opening 52 is provided below the rectifying plate 7. The rectifying plate 7 is located behind the burner 2. The rectifying plate 7 is in contact with the shielding plate 5 and is formed to fill the left and right width in the grill cabinet 10. The rectifying plate 7 is inclined downward and forwardly toward the front of the grill 10. In addition, the height of the front end 7 a that is the lowest position of the current plate 7 is set to be lower than the lower end height position of the opening 52 provided in the shielding plate 5. The rectifying plate 7 may be formed to extend straight in the horizontal direction without being inclined downward.

  However, since the combustion exhaust gas generated from the burner 2 has heat, it tends to flow upward from the burner 2 of the ceiling portion 11 of the grill cabinet 10 in the grill cabinet 10. The combustion exhaust gas from the burner 2 of the ceiling portion 11 of the grill 10 is caused to flow from the baffle 3 through the outlet 31 side of the flue 3 where the bubbling spilled out from the exhaust port 31 flows out. The flow which flows into the flue 3 from the intake 51 of upper part 32 of the inlet 32 of the flue 3 is formed so that it may not go to the rear wall part 12 grade | etc., Of the lower grill warehouse 10. FIG. Further, since the current plate 7 is inclined downwardly downward toward the front of the grill 10 and the height of the front end 7 a is set to be equal to or lower than the lower end height of the opening 52, the current plate 7 is generated from the burner 2 of the ceiling portion 11. It is possible to further promote the flow of the exhausted combustion exhaust gas toward the upper side of the inlet 32 of the flue 3 and to effectively prevent the combustion exhaust gas from flowing into the opening 52 around the lower side of the rectifying plate 7. Moreover, since the rear ceiling part 11a which is the ceiling part 11 of the grill 10 between the rear part of the burner 2 and the intake 51 is formed higher than the lower surface of the burner 2, the combustion exhaust gas generated from the burner 2 Is easy to flow upward before the entrance 32 of the flue 3. Accordingly, the combustion exhaust gas from the burner 2 is smoothly taken into the flue 3 without causing exhaust resistance or turbulent flow around the inlet 32 of the flue 3, and is efficiently guided to the exhaust port 31, Staying in the grill 10 is prevented. Therefore, the combustion secondary air is sufficiently supplied to the burner 2, and the burnability of the burner 2 can be improved.

  In addition, boiled oil that enters the flue 3 from the exhaust port 31 and flows out from the opening 52 at the inlet 32 of the flue 3 is discharged into the grill 10 below the current plate 7. And since the baffle plate 7 inclines downward toward the diagonally downward front of the grill 10 and the height of the front end 7a is set to be equal to or lower than the lower end height of the opening 52, the boiled material that has entered the flue 3 When the spillage exits from the opening 52, the spillage can be collected downward by the grill pan 15 arranged at the bottom of the grill cabinet 10. Therefore, the grill 1 can be easily and easily cleaned.

  A space 17 is provided at the lowermost part of the rear wall portion 12 of the grill cabinet 10 so that a part of the grill pan 15 is arranged further rearward than the rear wall portion 12. A dish 15 is provided. As a result, the boiled spill that enters the flue 3 and is discharged from the opening 52 to the grill 10 is reliably collected in the grill pan 15 without contaminating the bottom of the grill 10. Therefore, the dirt in the grill cabinet 10 is suppressed, and the grill 1 can be easily and easily cleaned.

  As described above, according to the grill 1 of the present embodiment, by providing the rectifying plate 7 at the inlet 32 of the flue 3, the combustion exhaust gas is efficiently taken into the flue 3 from the grill warehouse 10 and is burned into the burner 2. The secondary air can be sufficiently supplied to improve the combustibility of the burner 2. In addition, the spillage that has entered the flue 3 from the exhaust port 31 can be discharged into the grill compartment 10 from the opening 52 under the rectifying plate 7 without being retained in the flue 3, and the grill 1 can be easily cleaned. And it can be done easily.

In addition, this invention is not limited to the said embodiment, A various change is possible within the range of the summary of this invention.
For example, as shown in FIG. 3, in the flue 3, the second shielding plate 6 is inclined rearward at a position behind the temperature sensor 4 and inclined backward from the ceiling portion 34 of the flue 3 and extending downward. May be provided. As a result, the flow of the combustion exhaust gas in the flue 3 is not obstructed, and even if a flame generated in the grill 10 enters the flue 3, for example, the flame does not overflow from the exhaust port 31. It can be suppressed by the two shielding plates 6.
Further, the lower end height of the second shielding plate 6 is located higher than the upper end height of the shielding plate 5 at the flue inlet 32, and the shielding plate 5 and the second shielding plate 6 overlap each other when viewed in the front-rear direction. By providing the interval h so as not to match, an increase in exhaust resistance can be further suppressed, and exhaust of combustion exhaust gas can be improved.
Moreover, although it is set as the grill | grill incorporated in a gas stove in the said embodiment, this invention is applicable also to the grill provided separately from a gas stove.
