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

  The flange 260 is a square frame-like plate made of metal (for example, made of stainless steel or steel) 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 extending outward. is there. A pair of screw holes are provided at both ends of the flange 260 in the Y direction.

  The above-mentioned fire bed 200 can be attached with a leg (not shown). Therefore, the fire bed 200 can be used in a state where it is hollowly supported by the legs. Alternatively, the fire bed 200 can be used even when it is directly installed on a table or the like.

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

  Heated fuel such as charcoal or firewood is put into the fire floor cover 100 and the heated fuel is heated. A net or iron plate (not shown) is placed on the firebed cover 100 and the firebed 200. The foodstuff can be baked by placing the foodstuff on the net or iron plate.

  The firebed cover 100 and the barbecue grill as described above have the following technical characteristics. First, it is possible to suppress the thermal degradation of the fire bed 200 due to the heating of the heated fuel. The reason is as follows. The fire bed 200 is protected from heating of the heated fuel by a fire bed 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 fire bed cover 100 is accommodated in the fire bed 200, the first and second side walls 120 and 130 The gap G is generated between the first and second side walls 220 and 230. Since this gap G functions as air insulation, it is possible to reduce the influence of heating fuel on the first and second side walls 220 and 230. Since the portion other than the convex portion 111 of the bottom plate 110 of the firebed cover 100 is in contact with the bottom plate 210 of the firebed 200, the influence of heating fuel on the bottom plate 210 can be reduced.

  Secondly, contamination of the fire bed 200 can be prevented. This is because the heated fuel is put into the firebed cover 100 and the oil from the foods falls into the firebed cover 100, so that it is possible to prevent soot and oil from adhering to the firebed 200. is there.

  Third, the versatility of the firebed cover 100 can be improved. Because even if the vent of the firebed is not provided at a position corresponding to the vents 121 and 131 of the firebed cover 100, when the firebed cover 100 is accommodated in the firebed, A gap is formed between the second side walls 120 and 130 and the first and second side walls of the fire bed. By this gap, the vent holes 121 and 131 of the first and second side walls 120 and 130 communicate with the vent holes of the first and second side walls of the fire bed.

  Fourth, the firebed cover 100 is easy to dispose of. This is because the fire floor cover 100 is made of a flexible metal foil and can be rolled up and discarded.

  Fifth, the firebed cover 100 is stably supported by the firebed 200. This is because the inclination angles of the third and fourth side walls 140 and 150 of the firebed cover 100 are substantially the same as the inclination angles of the third and fourth side walls 240 and 250 of the firebed 200, and the third and fourth side walls 140. , 150 contacts the third and fourth side walls 240, 250. In addition, it is because the flange 160 of the firebed cover 100 is supported by the flange 260 of the firebed 200.

  Sixth, the heat dissipation effect of the fire floor 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 areas of the third and fourth side walls 140 and 150 are increased. Because you can.

  Seventh, a plurality of fire floor covers 100 can be stacked (stacked) one above the other. This is because the fire floor cover 100 extends obliquely upward so that the first and second side walls 120 and 130 are separated from each other, and the third and fourth sidewalls 140 and 150 extend obliquely upward so as to be separated from each other. .

In the third embodiment, the first and second parts 421 and 422 are provided with vent holes 425 that penetrate the first and second parts 421 and 422.

  The flange 430 is a ring-shaped plate made of metal (for example, made of stainless steel or steel) provided at the ring-shaped upper end of the side wall 420 and extending outward.

  The above-mentioned fire bed 400 can be attached with a leg (not shown). Therefore, the fire bed 400 can be used in a state where it is hollowly supported by the legs. Alternatively, the fire bed 400 can be used even when it is directly installed on a table or the like.

Hereinafter, a procedure for attaching the fire bed cover 300 to the fire bed 400 will be described. First, the fire bed cover 300 is accommodated in the fire bed 400. Then, a portion other than the convex portion of the bottom plate 310 of the firebed cover 300 comes into contact with the bottom plate 410 of the firebed 400. The flange 330 of the fire bed cover 300 is placed on the flange 430 of the fire bed 400. In this way, the fire bed cover 300 is supported by the fire bed 400. At the same time, the side wall 320 of the firebed cover 300 is disposed to face the side wall 420 of the firebed 400 with a gap G ″. As a result, the vent holes 321a and 322a of the side wall 320, the gap G ″, and the vent hole 425 of the side wall 420 are communicated.

  Heated fuel such as charcoal or firewood is put into the fire floor cover 300, and the heated fuel is heated. On the fire bed cover 300 and the fire bed 400, a net or iron plate (not shown) is placed. The foodstuff can be baked by placing the foodstuff on the net or iron plate.

  The fire bed cover 300 and the barbecue grill as described above have the following technical characteristics. First, it is possible to suppress the thermal degradation of the fire bed 400 due to the heating of the heated fuel. The reason is as follows. The fire bed 400 is protected from heating of the heated fuel by a fire bed cover 300 made of metal foil. The positional relationship between the side wall 320 and the side wall 420 is a positional relationship in which a gap G ″ is generated between the side wall 320 and the side wall 420 when the fire bed cover 300 is accommodated in the fire bed 400. Since the 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 fuel on the bottom plate 410 can be reduced.

  Secondly, contamination of the fire bed 400 can be prevented. This is because the heated fuel is put into the firebed cover 300 and the oil or the like from the food material falls into the firebed cover 300, so that it is possible to prevent soot and oil from adhering to the firebed 400. is there.

  Third, the versatility of the firebed cover 300 can be improved. This is because even if the vents of the firebed are not provided at positions corresponding to the vents 321a and 322a of the firebed cover 300, when the firebed cover 300 is accommodated in the firebed, A gap is created between the side walls of the fire bed. By this gap, the vent holes 321a and 322a of the side wall 320 and the vent hole of the side wall of the fire floor communicate with each other.

  Fourth, the firebed cover 300 is easy to dispose. This is because the fire floor cover 300 is made of a flexible metal foil and can be rolled up and discarded.

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

Sixth, the heat dissipation effect of the fire floor 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.

  Seventh, a plurality of firebed covers 300 can be stacked (stacked) one above the other. This is because the firebed cover 300 has the outer diameter and inner diameter of the side wall 320 gradually increased upward.
