[0002]

2. Description of the Related Art A grill is integrally provided on a gas stove for heating food such as fish. The grill has a substantially box-shaped steel grill case, and a heating means for heating an object to be cooked is provided on a ceiling portion thereof. Behind the grill cabinet, an exhaust pipe is provided for discharging exhaust gas such as smoke generated from the cooking object during cooking and hot air in the grill cabinet to the outside, and the exhaust pipe is an exhaust pipe provided on the top plate of the gas stove. It communicates with the mouth.

Here, as the heating means for the grill, for example, there is a Schwank type gas burner in which a plurality of flame openings are arranged on the surface of a ceramic plate, but the Schwank type gas burner has a problem that it is expensive. It was

Therefore, when the grill is to be manufactured at a low cost, a hot plate type heating means is often provided in the grill cabinet. The hot plate type heating means is composed of, for example, a metal heating plate having a predetermined area provided on the ceiling and a Bunsen type gas burner provided below the heating plate. Then, the gas burner heats the heating plate, and the radiant heat or infrared rays is used to cook the food. The heating plate is covered with an exhaust cover communicating with the exhaust pipe in order to prevent the ceiling of the grill from being overheated.

Further, the heating plate is provided with through holes of the same area in order to facilitate red heat due to the flame from the gas burner and to discharge the exhaust gas of the gas burner above the heating plate.

[0006]

By the way, in a grill (rear exhaust type grill) in which an exhaust pipe is connected to the rear of the grill cabinet, exhaust gas such as smoke generated from an object to be cooked during cooking and hot air in the grill cabinet is not generated. , Normally flows under the heating plate and between the heating plate and the exhaust cover to the exhaust stack.

Therefore, the exhaust gas flowing from the front of the grill to the exhaust stack concentrates heat on the rear of the grill. In this case, since the radiant heat from the heating plate for the object to be cooked placed on the grill is non-uniform, there is a problem that the grilling distribution of uniformly heating each part of the object to be cooked is deteriorated.

In view of the above problems, it is an object of the present invention to provide a rear exhaust type grill in which the radiant heat from the heating plate is uniform and the grilling distribution is improved.

[0009]

In order to solve this problem, a grill according to claim 1 is provided with a grill cabinet, an exhaust pipe for exhausting exhaust gas is connected to the rear of the grill cabinet, and the grill cabinet is mounted above the grill cabinet. In a grill provided with a heating plate type heating means having a heating plate in which a plurality of through holes are arranged in a row,
The opening area per unit area of the through hole of the heating plate is increased from the front to the rear of the grill case.

According to the first aspect of the present invention, when the gas burner is ignited, the flame from the gas burner causes the heating plate to glow red, and the radiant heat or infrared rays heats the food to be cooked placed on the grill. It In this case, in a grill having an exhaust tube connected to the rear side of the grill, heat tends to be concentrated in the rear, but the opening area per unit area of the through hole of the heating plate is increased from the front of the grill to the rear. Therefore, in the rear of the grill, a large amount of exhaust gas containing hot air is discharged to the exhaust stack through the through holes of the heating plate. Therefore, the heat is not concentrated in the rear of the grill, and the radiant heat from the heating plate for the food to be cooked placed on the grill is substantially uniform.

Further, the grill according to claim 2 is provided with a grill cabinet, an exhaust pipe for exhausting exhaust gas is connected to the rear of the grill cabinet, and a flame port is provided in the grill cabinet at least on the exhaust cylinder side of the grill cabinet. In the grill provided with the gas burner, a bypass passage for guiding the exhaust gas directly from the substantially central portion of the grill to the exhaust pipe is provided at the top of the grill.

According to the second aspect of the present invention, during cooking, exhaust gas such as smoke generated by heating the food to be cooked and hot air in the grill is discharged to the exhaust stack. In this case, since the bypass path for discharging the exhaust gas from the substantially central portion of the grill to the exhaust stack is provided at the top of the grill, the exhaust gas is also discharged from the bypass exhaust passage.

Therefore, the exhaust gas containing hot air generated between the front of the grill and the substantially central portion thereof is discharged through the bypass path, so that the heat is not concentrated on the rear of the grill and the grill is heated. The radiant heat from the heating plate for the object to be cooked placed on is substantially uniform.

According to the second aspect of the invention, a hot plate type heating means having a heating plate having a plurality of through holes arranged in a row is provided at the top of the grill case, and the through holes of the heating plate are provided per unit area. The opening area may be increased from the front to the rear of the grill cabinet.

As a result, the exhaust gas containing a large amount of hot air is discharged to the exhaust stack through the through holes of the heating plate, so that the heating plate for the food to be cooked placed on the grill is The radiant heat becomes more even.

Further, in the invention according to any one of claims 1 to 3, it is reduced that exhaust gas generated in front of the grill cabinet interferes with flame of a gas burner behind the grill cabinet to cause incomplete combustion. The food to be cooked can be heated while maintaining a stable combustion state of the gas burner.

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, reference numeral 1 indicates a gas stove provided with a grill of the present invention. The gas stove body 11 of the gas stove 1 is provided with two gas burners 13 facing the opening of the top plate 12. The operation of the gas burner 13 is performed by operating buttons 14 provided on the front panels 11a at both ends.
It is controlled by the firepower adjusting lever 15. The grill 2 for cooking food such as fish is provided below the top plate 12 and between the front panels 11a at both ends.

Referring to FIGS. 2, 3 and 4, the grill 2
Has a substantially rectangular parallelepiped steel-made grill case 21, and an exhaust pipe 22 communicating with an exhaust port 16 provided in the top plate 12 of the gas stove 1 is provided on the rear side of the grill case 21 (rear exhaust type grill). ).

As shown in FIG. 1, a grill door 23 in which heat-resistant glass is fitted to the open front surface of the grill cabinet 21.
Is detachably attached. A frame member 23a is detachably attached to the back surface of the grill door 23, the frame member 23a supports the grill plate 24, and the grill plate 24 is put in and taken out from the grill cabinet when the grill door 23 is opened and closed. The grill plate 24 formed in the shape of a plate also has a grill 2 on which an object to be cooked such as fish is placed.
Support 5.

A hot plate type heating means is provided on the top of the grill 2. The heating plate type heating means includes a substantially rectangular metal heating plate 3 provided on the ceiling so as to face the grill, and the heating plate 3
And a Bunsen type gas burner 4 for heating.

The gas burner 4 includes one mixing pipe 41,
Two burner main bodies 42 branched from the mixing pipe 41 in a substantially U-shape and having a plurality of flame openings 42a arranged in a row along the longitudinal direction of the grill 21 are provided. The flame openings 42a are located below the heating plate 3 and are attached to the side wall of the grill 21 so that the flame openings 42a face each other.

As shown in FIG. 4, the heating plate 3 having an opening in the center portion thereof facilitates red heat due to the flame from the gas burner 4 and discharges exhaust gas from the gas burner 4 above the heating plate 3. , A plurality of cut-and-raised protrusions 33 cut and raised toward the lower side of the grill 21 are formed on the tilted plate surfaces 31 and 32, which are bent in a mountain shape with a certain inclination from the center to both sides. Are arranged side by side along the longitudinal direction of the heating plate 3. Each cut-and-raised convex portion 33 is provided with a plurality of through holes 34 having a predetermined hole diameter arranged in a line in a direction perpendicular to the longitudinal direction of the heating plate 3.

Then, the gas burner 4 is ignited and the heating plate 3 is heated by the flame, and the cooking object placed on the grill 25 is cooked by its radiant heat or infrared rays. The heating plate 3 is covered with an exhaust cover 5 that communicates with the exhaust tube 22 in order to prevent the ceiling of the grill from being overheated.

Here, in the rear exhaust type grill 2, exhaust gas such as smoke generated from an object to be cooked during cooking and hot air in the grill chamber is provided below the heating plate 3 and between the heating plate 3 and the exhaust cover 5. It flows through to the exhaust pipe 22.

Therefore, the exhaust gas flowing from the front of the grill cabinet 21 to the exhaust stack 22 concentrates the heat on the rear side of the grill cabinet 21. In this case, since the radiant heat from the heating plate 3 for the cooking target placed on the grill 25 is non-uniform, the grilling distribution of uniformly heating each portion of the cooking target is deteriorated.

As shown in FIG. 4, in the present embodiment, the opening area per unit area of the through hole 34 of the heating plate 3 is made to increase in the direction from the front of the grill 21. That is, the region of the heating plate 3 provided with the cut-and-raised protrusions 33 is divided into three substantially equal parts along the longitudinal direction thereof, and the through holes 34 in the front side (the grill door 23 side) of the grill cabinet 21 are divided.
The opening area of a is small (for example, 3 mm), and the grill 21
The opening area of each through hole 34c on the rear side (exhaust pipe 22 side) is set to be large (for example, 3.8 mm). The opening area of each through hole 34b in the central portion was set to a substantially intermediate size (for example, 3.5 mm).

As a result, when the grill 2 is used, the through hole 3
Since the amount of exhaust gas including hot air guided to the exhaust pipe 22 through the 4c is large behind the grill cabinet 21, heat is not concentrated behind the grill cabinet 21 and the target placed on the grill 25 is not heated. Baking distribution is improved by uniformly heating each part of the cooked food.

Further, by discharging a large amount of exhaust gas above the heating plate 3 behind the grill cabinet 21, in particular, the grill cabinet 2
Exhaust gas generated in the rear of 1 and in front of the grill 21 is less likely to interfere with the flame of the gas burner 4, and the incomplete combustion of the gas burner is reduced.

Further, the exhaust cover 5 is provided with a bypass 51 for guiding the exhaust gas directly from the substantially central portion of the grill 21 to the exhaust tube 22. As a result, as shown by the arrow in FIG. 2, the exhaust gas generated from the front to the center of the grill 21 flows directly to the exhaust pipe 22 via the bypass passage 51.

As a result, below the heating plate 3 and the heating plate 3
The amount of the exhaust gas generated in the front of the grill cabinet 21 flowing between the exhaust cover 5 and the exhaust cover 5 is reduced, heat is not concentrated behind the grill cabinet 21, and the exhaust gas is the flame of the gas burner 4. Interference with is prevented.

Here, as in the present embodiment, the opening area per unit area of the through hole 34 of the heating plate 3 is increased from the front of the grill 21 toward the direction, and the bypass path 51 is provided. Therefore, the adjustment for making the grill distribution in the grill case 21 uniform can be performed more easily. Furthermore, by suppressing the interference of the exhaust gas with the flame of the gas burner 4 and preventing the occurrence of incomplete combustion, stable combustion of the gas burner can be secured.

In the present embodiment, the bypass 2 is provided in the grill 2 provided with the hot plate type heating means. However, the present invention is not limited to this, and the flame outlet is provided at least on the exhaust pipe side of the grill. If you have a gas burner you have,
It is possible to prevent interference between the exhaust gas and the flame of the gas burner behind the grill.
