[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grill pan having a grill pan which can be taken in and out through an opening provided in front of the grill pan and a grill which holds the food above the grill pan. The present invention relates to a grill device that heats and cooks using a cooking heat source provided on a surface.

[0002]

2. Description of the Related Art A conventional grilling apparatus of this type is disclosed, for example, in Japanese Patent Application Laid-Open No. Hei 8-94093, in which outside air is opened from an air hole formed in a side wall of a grill storage so that the temperature of a grill pan does not become high during cooking. It is known that the air is introduced into a grill cabinet to guide the outside air to the surface of a grill pan. The publication describes that the air holes are simply formed on the side wall of the grill storage, but the attached drawings show that the air holes are formed on the side wall on the back side where the exhaust port is formed. Only examples are given.

[0003]

In the conventional grilling apparatus described in the above publication, the outside air is guided from the air holes to the surface of the grill pan, so that the portion to which the outside air is guided is cooled. The part away from the cooling is not always cooled. Even with the above-mentioned conventional one, it would be possible to cool the whole grill pan by providing a large number of air holes so as to surround the grill pan. The temperature in the refrigerator decreases, and cooking is impaired.

[0004] In view of the above problems, an object of the present invention is to provide a grill device that can efficiently cool a grill pan with a small amount of air.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a grill storage having an opening at the front and an exhaust port connected to the rear, wherein a grill for cooking is provided on a ceiling surface of the grill. A device having a heat source, a grill pan which can be taken in and out of the opening and a grill which holds the food above the grill pan, and which opens and closes the opening with a grill door. In addition to being formed of a metal plate, an air inlet for introducing air from the front into the grill chamber when the opening is closed by the grill door is formed, and the outside air flowing into the grill chamber from the air inlet is supplied to the grill pan. And an air outlet through the space between the wire and the net.

[0006] Outside air flowing from an intake port provided in front of the grill warehouse flows toward an exhaust port connected to the rear of the grill store. If the outside air is guided to the exhaust port through the space between the grill pan and the grill net, the outside air flowing from the air inlet flows from the front to the rear of the grill pan while cooling the entire surface of the grill pan. In addition, since the net portion of the grill is formed of a metal plate, radiant heat from the cooking heat source provided on the ceiling surface of the grill cabinet to the grill pan is cut off, and outside air is supplied between the net portion and the grill pan. Can be flowed more efficiently. Therefore, even with a small amount of outside air, the entire grill pan can be efficiently cooled.

[0007] When the net portion is formed in a flat plate shape, the contact area with the food becomes large, and there is a possibility that the food is seized on the net portion. In this case, the net portion may be formed in a wavy shape bent along a longitudinal folding line in the front-rear direction or the left-right direction, and a drainage hole may be formed in a valley of the net portion.

Further, if a side wall sandwiching the space between the mesh portion and the grill pan is provided in the left-right direction, the outside air flowing from the front to the rear does not leak out of the grill pan, and the outside air is effectively used for cooling. Can be.

By the way, in order to prevent the outside air from leaking above the grill through the juice drain hole formed in the grill when the outside air flows from the front to the rear below the grill, The juice draining hole may be formed so that the position of the rear edge of the juice draining hole is located above the position of the front edge of the juice draining hole.

On the other hand, if the juice draining hole is formed such that the position of the rear end edge of the juice draining hole is located below the position of the front edge of the juice draining hole, the rear edge of the juice draining hole can be formed. The distribution of the radiant heat reaching the grill pan from the upper fire through the juice drain hole is shifted to the front of the grill pan as compared with the one in which the position is located above the position of the front edge of the juice drain hole. Since the outside air flows from the front, the temperature of the outside air is lower as it is further forward. Therefore, the temperature distribution of the grill pan heated by the radiant heat passing through the juice drain hole can be more effectively cooled by setting the temperature of the front portion to be higher.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a grill device, which has a grill storage 2 therein. The grill storage 2
A ceramic plate-type upper fire burner 21 for irradiating infrared rays, which are a heat source for cooking, downward, is attached to the ceiling surface of the heater. A partition wall 22 that partitions the passage connected to the exhaust port 23 into a rear passage 22a and a front passage 22b is provided behind the grill warehouse 2 over the entire width of the grill warehouse 2 in the left-right direction. A grill door 3 for opening and closing the opening of the grill storage 2 is provided in front of the grill storage 2. A grill pan 4 and a grill 5 set on the grill pan 4 are provided in the grill storage 2 so as to be able to freely enter and exit through a front opening. The grill 5 is a net 5 on which the food is placed.
1 and leg plates 52 attached to the left and right of the net portion 51. The outside air is introduced into the grill storage 2 through a plurality of openings 32 formed at the back of the finger hook 31 of the grill door 3, and the introduced outside air is supplied to the mesh 51 and the grill pan 4. The grill pan 4 is cooled while flowing from the front to the back. Then, the outside air flowing to the rear of the grill pan 4 is discharged from the exhaust port 23 through the rear passage 22a. The amount of combustion of the upper fire burner 21 is suppressed to be lower than the amount of combustion of the upper fire burner in a normal grill device. Although the combustion amount of the upper fire burner in a normal grill device is generally about 2100 kcal / hour, in the present embodiment, the calorific value of the upper fire burner 21 is 1250 h / hour.
kcal. However, if the calorific value of the upper fire burner 21 is reduced in this manner, the heating performance for the cooked food is reduced. Therefore, the passage area of the front passage 22b is set to be small, and it is difficult for the hot air in the space sandwiched between the upper fire burner 21 and the net portion 51 to be exhausted from the exhaust port 23, so that the ambient temperature around the food is high. It was kept as it was. on the other hand,
The temperature of the gas discharged through the front passage 22b becomes high for the above-described reason, and therefore a strong draft occurs even if the passage area of the front passage 22b is small. The front passage 22b
The exhaust of the rear passage 22a is smoothly drawn out by the draft. As a result, the outside air flowing from the front to the rear between the net portion 51 and the grill pan 4 can be guided to the rear passage 22a and discharged from the exhaust port. In this embodiment, the notch 52b is formed in the leg plate 52 for weight reduction.

The grill pan 4 and the grill door 3 are connected by a connecting member 41 bent in a substantially U-shape. When two ridges 41a formed at two locations on the back side of the connecting member 4 are inserted from below into an opening formed on the flange on the back side of the grill pan 4, the grill door 3 is moved together with the front portion of the connecting member 41. , The grill door 3 is pulled forward, and the grill pan 4 is moved to the grill storage 2.
The grill door 3 is lowered in a state where the grill door 3 is pulled out from the grill door 3 by a predetermined amount. A mounting bracket 42 for detachably attaching the connecting member 41 to the grill door 3 is provided at a front end portion of the connecting member 41.
Is caulking. Engaging claws 44 are protrudingly provided at two places on the left and right sides of the upper side of the mounting bracket 42, and the inner wall 33 of the grill door 3 is provided.
The engaging claws 44 are inserted into the engaging holes 35 formed on the inner wall 3.
The lower side of the mounting member 42 is pressed by the pressing spring 36 protruding from the position 3 to hold the mounting member 42 on the inner wall 33. A plurality of openings 34 are provided in the inner wall 33 in a lateral direction. On the other hand, a plurality of openings 43 are also provided side by side on the front surface of the mounting bracket 42. When the mounting bracket 42 is attached to the inner wall 33, the opening 34 of the inner wall 33 and the opening 43 of the mounting bracket 42 coincide with each other. The outside air introduced from the opening 32 formed on the back side of the finger rest 31 is introduced into the grill storage 2 through the opening 34 and the opening 43. The opening 32, the opening 34, and the opening 4
3 constitutes an intake port.

Referring to FIG. 3, net 51 of grill 5 is folded so that the fold is in the left-right direction, and has a trough having one trough and two peaks sandwiching the trough. The units 51a are arranged in the front-rear direction while leaving a gap therebetween. A window hole-shaped juice draining hole 53 that is long in the left-right direction is formed between the valley portion of the grilling net unit 51a and each of the grilling net units 51a. Note that downward tongue pieces 52a formed in front and rear of the leg plate 52 are inserted into engagement holes 4a formed in the flange of the grill pan 4, and the grill 5 is positioned with respect to the grill pan 4. When the grill 5 is placed in the grill 2, as shown in FIG.
It is formed such that there is almost no gap between the side walls 24 of the grill storage 2 and the leg plate 52. Therefore, when the outside air flows from the front to the back between the net portion 51 and the grill pan 4, even if the outside air tries to leak outside from the leg plate 52 in the left-right direction through the notch 52 b, the outside air is covered by the left and right side walls 24. The outside air does not leak from the notch 52b. When the side wall 24 is separated from the leg plate 52 to some extent or when it is desired to completely prevent the leakage of the outside air, the cutout 52b is formed in the leg plate 52.
Is not formed. The bottom surface of the grill pan 4 is formed so that the central portion 44 in the left-right direction is lower than the side portions 45. With such a configuration, the broth and the like dropped from the net portion 51 accumulate in the central portion 44 of the grill pan 4.
By the way, the central portion 44 is in contact with the bottom surface 25 of the grill storage 2 over the entire area of the central portion 44, and the heat of the grill pan 4 is transmitted through the central portion 44 to the bottom surface 25 of the grill storage 2.
It is transmitted to and cooled. Accordingly, the entire grill pan 4 is cooled by the outside air, but the central portion 44 in which the broth is stored is cooled by the heat drawn to the bottom surface 25 of the grill storage 2.

In the present embodiment, the juice drain hole 53 is provided.
Was formed such that the front edge 53a of the juice draining hole 53 was located above the rear edge 53b. When the juice draining hole 53 is formed so as to be directed forward, the radiant heat reaching the grill pan 4 from the upper fire burner 21 through the juice draining hole 53 is inclined forward from below vertically below the juice draining hole 53. Although the grill pan 4 is heated by the radiant heat transmitted through the juice drainage hole 53, when the transmitted radiant heat is inclined forward as described above, the grill pan 4 is not uniformly heated in the front-rear direction, but in the first half of the latter half. The part is more heated. FIG. 6 shows that the upper fire burner 21
It is a figure which shows the bottom surface temperature of the grill pan 4 when burning is continued continuously for time. Juice drain hole 53 as in this embodiment
Is tilted forward, the temperature distribution becomes as shown by F in FIG. That is, the temperature of the first half of the grill pan 4 becomes higher than the temperature of the second half. Since the outside air for cooling flows from the front to the back on the upper surface of the grill pan 4 as described above, the higher the temperature of the first half in which the outside air comes in contact with the low temperature state, the higher the cooling efficiency. By the way, in FIG.
The temperature distribution indicated by is a case where the front edge of the juice drainage hole is lower than the rear end edge thereof so that the juice drainage hole faces backward, contrary to the above embodiment. When the juice draining hole is directed backward, the temperature of the second half of the grill pan 4 becomes higher than the temperature of the first half thereof, and the cooling efficiency of the grill pan 4 is slightly reduced. However, as in the above embodiment, the juice drain hole 53
If the air is directed forward, there is a possibility that the outside air for cooling may take up the juice drain hole 53 and leak above the net portion 51. When the outside air leaks above the net portion 51 through the juice drain hole 53 in this way, not only does the outside air for cooling decrease, the cooling amount for the grill pan 4 decreases, but also the cooking placed on the net portion 51. In some cases, grill cooking is hindered by lowering the temperature around the object. In such a case, by directing the juice draining hole backward, it is possible to prevent outside air from leaking above the net portion 51 through the juice draining hole. By the way, in the above-described embodiment, the net portion is bent in the left-right direction along the long bending line, and the peak and the valley are alternately continuous in the front-back direction. However, the net portion is bent along the long bending line in the front-back direction, and The peaks and valleys may be formed in a wave shape that is alternately continuous in the direction. Further, in the above-described embodiment, the net portion 51 is formed by bending a plate material by sheet metal processing, but there is no problem if it is formed by casting a casting or the like.

Although the grill pan 4 can be freely taken in and out of the grill storage 2 together with the grill door 3 by the connecting member 41 connected to the grill door 3, the grill pan 4 may be directly connected to the grill door 3. Alternatively, the grill door 3 may be pivotally supported near the lower edge of the opening on the front surface of the grill cabinet 2 to open and close the opening, and the grill pan 4 may be taken in and out by a handle or the like.

[0016]

As is apparent from the above description, according to the present invention, the outside air introduced into the grill chamber is caused to flow between the grill and the grill pan, so that the temperature around the food is not reduced. The grill pan can be cooled by efficiently using a small amount of outside air.
