Therefore, it becomes possible to take outside air into the grate cover through the vents and gaps in the grate and the vents in the grate cover.

The bottom plate may have a rectangular shape. The bottom plate has a first end in a first direction, a second end opposite to the first end, a third end in a second direction intersecting the first direction, and an opposite side to the third end. It is possible to have a configuration having a fourth end. The side walls of the grate cover include a first side wall erected at the first end of the bottom plate, a second side wall erected at the second end of the bottom plate, and the third end of the bottom plate. It is possible to have a configuration including a third side wall erected and a fourth side wall erected at the fourth end of the bottom plate.

The first and second side walls may extend obliquely upward so that the distance between the first and second side walls gradually increases.

The third and fourth side walls may extend obliquely upward so that the distance between the third and fourth side walls gradually increases. When the first, second, third, and fourth side walls extend obliquely upward as described above, a plurality of the grate covers can be stacked one above the other.

The third and fourth side walls may be able to abut on opposing portions of the side wall of the fire bed that are opposite to the third and fourth side walls, respectively. When the fire bed cover of this type is housed in the fire bed, the third and fourth side walls come into contact with the opposing parts of the fire bed and are supported, so that the fire bed cover is stable within the fire bed. Retained.

At least one of the first to fourth side walls may be provided with a plurality of protrusions or a plurality of recesses. In the case of the firebed cover of this embodiment, the surface area of at least one of the first to fourth side walls is increased by the convex portion or the concave portion. Therefore, the heat dissipation effect of the grate cover is improved.

The grate cover may further include a flange. The flange may be provided at an upper end of at least one of the first to fourth side walls, extend outward, and be placed on the side wall of the fire bed. In the case of such a fire bed cover, the flange is placed on the side wall of the fire bed, thereby stabilizing the state in which the fire bed cover is accommodated in the fire bed.

The bottom plate may be a disk. The bottom plate may have a ring-shaped end. The side wall of the grate cover may be a cylinder erected at the end of the bottom plate.

The side wall of the grate cover may be configured to extend obliquely upward so that the outer diameter and inner diameter of the side wall gradually expand upward. In the case of such a grate cover, a plurality of grate covers can be stacked one on top of the other.

The side wall of the grate cover may be provided with a plurality of protrusions or a plurality of recesses. In the case of such a firebed cover, the surface area of the side wall is increased by the convex portion or the concave portion. Therefore, the heat dissipation effect of the grate cover is improved.

The grate cover may further include a flange. The flange may be provided on at least a portion of the upper end of the side wall, extend outward, and be able to be placed on the side wall of the grate. In the case of such a fire bed cover, the flange is placed on the side wall of the fire bed, thereby stabilizing the state in which the fire bed cover is housed in the fire bed.

In other words, the third side wall 240 is inclined to one side in the X direction (outside the grate 200), and the fourth side wall 250 is inclined to the other side in the X direction (outside the grate 200). .

The flange 260 is a rectangular frame-shaped plate made of metal (for example, made of stainless steel or steel) that is provided at the upper ends of the first side wall 220, the second side wall 230, the third side wall 240, and the fourth side wall 250 and extends outward. be. A pair of screw holes are provided at both ends of the flange 260 in the Y direction.

Legs (not shown) can be attached to the fire bed 200 described above. Therefore, the fire bed 200 can be used while being supported in the hollow by the legs. Alternatively, the fire bed 200 can also be used in a state where it is placed directly on a table or the like.

The procedure for attaching the fire bed cover 100 to the fire bed 200 will be described below. First, the fire bed cover 100 is housed in the fire bed 200. Then, the portion of the bottom plate 110 of the fire bed cover 100 other than the convex portion 111 comes into contact with the bottom plate 210 of the fire bed 200. The third and fourth side walls 140 and 150 of the fire bed cover 100 abut against the third and fourth side walls 240 and 250 of the fire bed 200. Flange 160 of grate cover 100 rests on flange 260 of grate 200. In this way, the grate cover 100 is supported by the grate 200. At the same time, the first and second side walls 120 and 130 of the fire bed cover 100 are arranged to face the first and second side walls 220 and 230 of the fire bed 200 with a gap G therebetween. Thereby, the ventilation hole 121 of the first side wall 120, the gap G, and the ventilation hole 270 of the first side wall 220 communicate with each other. The ventilation hole 131 of the second side wall 130, the gap G, and the ventilation hole of the second side wall 230 communicate with each other.

A heating fuel such as charcoal or firewood is put into this fire bed cover 100 and the heating fuel is heated. A net or iron plate (not shown) is placed on the fire bed cover 100 and the fire bed 200. The food can be placed on this grid or iron plate and grilled.

The grate cover 100 and barbecue grill as described above have the following technical features. First, thermal deterioration of the grate 200 due to heating of the heated fuel can be suppressed. The reason is as follows. The grate 200 is protected from heating by the heated fuel by a grate cover 100 made of metal foil. The positional relationship between the first and second side walls 120 and 130 and the first and second side walls 220 and 230 is such that when the grate cover 100 is housed in the grate 200, the first and second side walls 120 and 130 are The positional relationship is such that a gap G is created between the first and second side walls 220 and 230. Since this gap G functions as air insulation, the influence of heating of the heated fuel on the first and second side walls 220 and 230 can be reduced. Since the portion of the bottom plate 110 of the fire bed cover 100 other than the convex portion 111 is in contact with the bottom plate 210 of the fire bed 200, the influence of heating of the heating fuel on the bottom plate 210 can be reduced.

Second, the fire bed 200 can be prevented from becoming dirty. This is because heating fuel is put into the grate cover 100 and oil from the food falls into the grate cover 100, so it is possible to prevent soot, oil, etc. from adhering to the grate 200. be.

Thirdly, the versatility of the grate cover 100 can be improved. This is because, even if the vents of the grate are not provided at positions corresponding to the vents 121 and 131 of the grate cover 100, when the grate cover 100 is housed in the grate, the first, A gap is created between the second side walls 120, 130 and the first and second side walls of the grate. This gap allows the ventilation holes 121, 131 of the first and second side walls 120, 130 to communicate with the ventilation holes of the first and second side walls of the grate.

Fourth, the grate cover 100 is easy to dispose of. This is because the fire bed cover 100 is made of flexible metal foil, so it can be rolled up and thrown away.

Fifth, the fire bed cover 100 is stably supported by the fire bed 200. This is because the angle of inclination of the third and fourth side walls 140 and 150 of the fire bed cover 100 is approximately the same as the angle of inclination of the third and fourth side walls 240 and 250 of the fire bed 200. , 150 abut against the third and fourth side walls 240, 250. In addition, the flange 160 of the grate cover 100 is supported by the flange 260 of the grate 200.

Sixthly, the heat dissipation effect of the fire bed cover 100 is improved. This is because the third and fourth side walls 140 and 150 are provided with a plurality of convex portions 141 and 151 at intervals in the Y direction, so that the surface area of the third and fourth side walls 140 and 150 can be increased. This is because it can be done.

Seventhly, a plurality of grate covers 100 can be stacked vertically. This is because the fire bed cover 100 has first and second side walls 120, 130 extending diagonally upward away from each other, and third and fourth side walls 140, 150 extending diagonally upward away from each other. .

At the same time, the side wall 320 of the fire bed cover 300 is arranged to face the side wall 420 of the fire bed 400 with a gap G'' therebetween. This allows the ventilation holes 321a and 322a of the side wall 320, the gap G'', and the ventilation hole 425 of the side wall 420 to communicate with each other.

A heating fuel such as charcoal or firewood is put into this fire bed cover 300 and the heating fuel is heated. A net or iron plate (not shown) is placed on the fire bed cover 300 and the fire bed 400. The food can be placed on this grid or iron plate and grilled.

The grate cover 300 and barbecue grill as described above have the following technical features. First, thermal deterioration of the grate 400 due to heating of the heated fuel can be suppressed. The reason is as follows. The grate 400 is protected from heating by the heated fuel by a grate cover 300 made of metal foil. The positional relationship between the side walls 320 and the side walls 420 is such that a gap G'' is created between the side walls 320 and the side walls 420 when the fire bed cover 300 is housed in the fire bed 400. Since this gap G'' functions as air insulation, the influence of heating of the heated fuel on the side wall 420 can be reduced. Since the portion other than the convex portion of the bottom plate 310 of the fire bed cover 300 is in contact with the bottom plate 410 of the fire bed 400, the influence of heating of the heating fuel on the bottom plate 410 can be reduced.

Second, the fire bed 400 can be prevented from becoming dirty. This is because heating fuel is put into the grate cover 300 and oil from the food falls into the grate cover 300, so it is possible to prevent soot, oil, etc. from adhering to the grate 400. be.

Thirdly, the versatility of the grate cover 300 can be improved.

This gap allows the ventilation holes 321a, 322a in the side wall 320 to communicate with the ventilation holes in the side wall of the grate.

Fourth, the grate cover 300 is easy to dispose of. This is because the fire bed cover 300 is made of flexible metal foil, so it can be rolled up and thrown away.

Fifth, the fire bed cover 300 is stably supported by the fire bed 400. This is because the flange 330 of the grate cover 300 is supported by the flange 430 of the grate 400.

Sixthly, the heat dissipation effect of the fire bed cover 300 is improved. This is because the third and fourth portions 323 and 324 of the side wall 320 are provided with a plurality of convex portions at intervals in the circumferential direction, so that the surface area of the side wall 320 can be increased.

Seventhly, a plurality of grate covers 300 can be stacked vertically.
This is because the outer diameter and inner diameter of the side wall 320 of the fire bed cover 300 gradually increase in diameter upward.
