Description

The present invention relates to a fire bed cover that can be placed in the fire bed of a barbecue grill and a barbecue grill equipped with the same.

One such barbecue grill is described in Patent Document 1 below. This barbecue grill is equipped with a disposable fire bed. This fire bed has a cardboard box and an aluminum foil sheet attached to the inside of the box.

Utility Model Registration No. 3015275

The fire bed is simply a cardboard box with an aluminum foil sheet attached to the inside, so there is a possibility that the sheet will peel off when heated by the heating fuel, such as charcoal or firewood, inside the fire bed. If the sheet peels off, it will no longer be able to protect the box from the heat of the heating fuel.

The present invention was devised in light of the above circumstances, and its purpose is to provide a fire bed cover that can prevent the fire bed from thermally deteriorating due to the heating of the heating fuel, and a barbecue grill equipped with the same.

In order to solve the above problems, the fire bed cover of the present invention is a box made of flexible metal foil and capable of storing heating fuel inside, which is placed inside the fire bed made of metal plates of a barbecue grill. This fire bed cover has a bottom plate and side walls erected at the ends of the bottom plate. When using a fire bed cover of this type, heating fuel is inserted into the fire bed cover stored in the fire bed and heated. However, since the fire bed cover protects the fire bed from the heating of the heating fuel, it is possible to suppress thermal deterioration of the fire bed due to the heating of the heating fuel. Moreover, the fire bed cover can prevent soot and oil from food ingredients (meat) from adhering to the inner surface of the fire bed.

At least a portion of the side wall of the fire bed cover can be configured to be arranged opposite the side wall of the fire bed with a gap. When a fire bed cover of this type is placed inside the fire bed, a gap is created between at least a portion of the side wall of the fire bed cover and the side wall of the fire bed. This gap functions as air insulation, so that it is possible to further suppress thermal deterioration of the side wall of the fire bed due to heating by the heating fuel inside the fire bed cover.

The fire bed cover may be configured so that a vent hole is provided in the portion of the side wall that penetrates the portion. The vent hole may be configured so that it can communicate with the vent hole provided in the side wall of the fire bed through the gap. With a fire bed cover of this type, even if the vent hole in the fire bed cover is not provided in a position corresponding to the vent hole in the fire bed, the vent hole in the fire bed and the vent hole in the fire bed cover housed within the fire bed are connected by the gap. Therefore, it becomes possible to take in outside air into the fire bed cover through the vent hole in the fire bed, the gap, and the vent hole in the fire bed cover.

The bottom plate may be rectangular. The bottom plate may have 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 a fourth end opposite to the third end. The side walls of the fire bed cover may have 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, a third side wall erected at the third end of the bottom plate, and a fourth side wall erected at the fourth end of the bottom plate.

The first and second side walls can be configured to extend diagonally upward so that the distance between the first and second side walls gradually increases.

The third and fourth side walls can be configured to extend diagonally upward so that the distance between the third and fourth side walls gradually increases. When the first, second, third and fourth side walls extend diagonally upward as described above, multiple fire bed covers can be stacked one on top of the other.

The third and fourth side walls can be configured to abut against the opposing portions of the side walls of the fire bed that face the third and fourth side walls, respectively. When a fire bed cover of this type is stored in the fire bed, the third and fourth side walls abut against and are supported by the opposing portions of the fire bed, so that the fire bed cover is stably held within the fire bed.

It is possible to configure at least one of the first to fourth side walls to have multiple protrusions or multiple recesses. With a fire bed cover of this type, the surface area of at least one of the first to fourth side walls is increased by the protrusions or recesses. This improves the heat dissipation effect of the fire bed cover.

The fire bed cover can be further configured to include a flange. The flange can be provided at the upper end of at least one of the first to fourth side walls, extend outward, and be configured to be able to be placed on the side wall of the fire bed. With a fire bed cover of this type, the flange is placed on the side wall of the fire bed, thereby stabilizing the state in which the fire bed cover is contained within the fire bed.

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

The side walls of the fire bed cover can be configured to extend diagonally upward so that the outer and inner diameters of the side walls gradually expand upward. With a fire bed cover of this type, multiple fire bed covers can be stacked one on top of the other.

The side walls of the fire bed cover can be configured with multiple protrusions or multiple recesses. In the case of a fire bed cover of this type, the surface area of the side walls is increased by the protrusions or recesses. This improves the heat dissipation effect of the fire bed cover.

The fire bed cover can further include a flange. The flange can be provided on at least a portion of the upper end of the side wall, extend outward, and be capable of being placed on the side wall of the fire bed. With a fire bed cover of this type, the flange is placed on the side wall of the fire bed, thereby stabilizing the state in which the fire bed cover is contained within the fire bed.

The bottom plate can be provided with a convex portion. In the case of the fire bed cover of this type, the convex portion can reduce the contact area of the bottom plate of the fire bed cover with the bottom plate of the fire bed. Therefore, it is possible to suppress the thermal deterioration of the bottom plate of the fire bed caused by the heating of the heating fuel in the fire bed cover.

The barbecue grill of the present invention comprises a fire bed and a fire bed cover of any of the above-mentioned aspects. The fire bed cover is housed within the fire bed.

Below, we will explain Examples 1 to 3 of the present invention.

First, the fire bed cover 100 according to the first embodiment of the present invention will be described with reference to Figs. 1A to 1E. The fire bed cover 100 is a box that can be accommodated in the fire bed 200 (see Figs. 2A to 2B), and is made of flexible metal foil (e.g., aluminum foil). The fire bed cover 100 has a bottom plate 110, a first side wall 120, a second side wall 130, a third side wall 140, a fourth side wall 150, and a flange 160. Each component of the fire bed cover 100 will be described in detail below. Y in Figs. 1A and 1C indicates the length direction of the fire bed cover 100 and the first direction in the claims. X in Figs. 1A and 1C indicates the width direction of the fire bed cover 100 and the second direction in the claims. The X direction is perpendicular to the Y direction.

The bottom plate 110 is a rectangular plate made of metal foil (e.g., aluminum foil). The Y-direction dimension of the bottom plate 110 is smaller than the Y-direction dimension of a bottom plate 210 (see FIG. 2B) of the fire bed 200 (described later). The X-direction dimension of the bottom plate 110 is slightly smaller than the X-direction dimension of the bottom plate 210 of the fire bed 200. The bottom plate 110 has a convex portion 111, a first end 112, a second end 113, a third end 114, and a fourth end 115.

The convex portion 111 is a protruding ridge that protrudes upward from the bottom plate 110. The portion of the bottom plate 110 other than the convex portion 111 can abut against the bottom plate 210 of the fire bed 200.

The first end 112 is the end on one side of the bottom plate 110 in the Y direction. The second end 113 is the end on the other side of the bottom plate 110 in the Y direction (the opposite side of the first end 112). The third end 114 is the end on one side of the bottom plate 110 in the X direction. The fourth end 115 is the end on the other side of the bottom plate 110 in the X direction (the opposite side of the third end 114).

The first side wall 120 is a trapezoidal plate made of metal foil (e.g., aluminum foil) erected on the first end 112 of the bottom plate 110. The second side wall 130 is a trapezoidal plate made of metal foil (e.g., aluminum foil) erected on the second end 113 of the bottom plate 110. The first side wall 120 and the second side wall 130 extend obliquely upward so that the distance between the first and second side walls 120, 130 gradually increases. In other words, the first side wall 120 is inclined to one side in the Y direction (the outside of the fire bed cover 100), and the second side wall 130 is inclined to the other side in the Y direction (the outside of the fire bed cover 100). The height dimension of the first and second side walls 120, 130 is slightly larger (by the thickness of the flange 160) than the height dimension of the first and second side walls 220, 230 (see FIG. 2A) of the fire bed 200 described later. The first and second side walls 120, 130 (at least a part of the side walls of the fire bed cover in the claims) can be arranged opposite the first and second side walls 220, 230 of the fire bed 200 with a gap G (see FIG. 2A). At the lower end of the first side wall 120, a plurality of ventilation holes 121 penetrating the first side wall 120 are provided at intervals in the X direction. At the lower end of the second side wall 130, a plurality of ventilation holes 131 penetrating the second side wall 130 are provided at intervals in the X direction. The ventilation holes 121 and 131 can communicate (ventilate) with the ventilation holes (see FIG. 2B) in the fire bed 200, which will be described later, via the gap G.

The third side wall 140 is a trapezoidal plate made of metal foil (e.g., aluminum foil) erected at the third end 114 of the bottom plate 110. The third side wall 140 connects one end of the first and second side walls 120 and 130 in the X direction. The fourth side wall 150 is a trapezoidal plate made of metal foil (e.g., aluminum foil) erected at the fourth end 115 of the bottom plate 110. The fourth side wall 150 connects the other end of the first and second side walls 120 and 130 in the X direction. The third side wall 140 and the fourth side wall 150 extend obliquely upward so that the distance between the third and fourth side walls 140 and 150 gradually increases. In other words, the third side wall 140 is inclined to one side in the X direction (outside the fire bed cover 100), and the fourth side wall 150 is inclined to the other side in the X direction (outside the fire bed cover 100). The height dimension of the third and fourth side walls 140, 150 is slightly larger (by the thickness of the flange 160) than the height dimension of the third and fourth side walls 240, 250 (see FIG. 2B) of the fire bed 200 described later. The inclination angle of the third and fourth side walls 140, 150 is approximately the same as the inclination angle of the third and fourth side walls 240, 250 of the fire bed 200. The third and fourth side walls 140, 150 can abut against the third and fourth side walls 240, 250 (opposing parts). The third side wall 140 has protrusions 141 spaced apart in the Y direction. The convex portion 141 is convex toward the inside of the fire bed cover 100 and extends in the inclined direction of the third side wall 140. The fourth side wall 150 has convex portions 151 spaced apart in the Y direction. The convex portions 151 are convex toward the inside of the fire bed cover 100 and extend in the inclined direction of the fourth side wall 150. The first to fourth side walls 120 to 150 correspond to the side walls in the claims.

The flange 160 is a rectangular frame-shaped plate made of metal foil (e.g., aluminum foil) that is provided on the upper ends of the first side wall 120, the second side wall 130, the third side wall 140, and the fourth side wall 150 and extends outward. A pair of notches 161 are provided on both ends of the flange 160 in the Y direction at positions corresponding to the screw holes (not shown) of the fire bed 200.

The fire bed cover 100 having the above-mentioned configuration is made of a flexible metal foil (e.g., 0.0 mm thick).
It is manufactured by press-molding aluminum foil (0.35 to 0.06 mm thick) using a mold not shown.

The barbecue grill according to the first embodiment of the present invention will be described below with reference to Figures 2A to 2B. The barbecue grill shown in Figures 2A to 2B includes a fire bed cover 100 and a fire bed 200. This barbecue grill will be described in detail below.

The fire bed 200 is a metal (e.g., stainless steel or steel) box capable of housing the fire bed cover 100. The fire bed 200 has a bottom plate 210, a first side wall 220, a second side wall 230, a third side wall 240, a fourth side wall 250, and a flange 260.

The bottom plate 210 is a rectangular plate made of metal (e.g., stainless steel or steel). The bottom plate 210 has a first end 211, a second end 212, a third end 213, and a fourth end 214. The first end 211 is an end on one side of the bottom plate 210 in the Y direction. The second end 212 is an end on the other side of the bottom plate 210 in the Y direction (the opposite side of the first end 211). The third end 213 is an end on one side of the bottom plate 210 in the X direction. The fourth end 214 is an end on the other side of the bottom plate 210 in the X direction (the opposite side of the third end 213).

The first side wall 220 is a trapezoidal metal plate (e.g., stainless steel or steel) erected at the first end 211 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The second side wall 230 is a trapezoidal metal plate (e.g., stainless steel or steel) erected at the second end 212 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The lower end of the first side wall 220 is provided with an air vent 270 penetrating the first side wall 220. The lower end of the second side wall 230 is provided with an air vent (not shown) penetrating the second side wall 230.

The third side wall 240 is a rectangular metal plate (e.g., stainless steel or steel) erected at the third end 213 of the bottom plate 210. The third side wall 240 connects one end of the first and second side walls 220 and 230 in the X direction. The fourth side wall 250 is a rectangular metal plate (e.g., stainless steel or steel) erected at the fourth end 214 of the bottom plate 210. The fourth side wall 250 connects the other end of the first and second side walls 220 and 230 in the X direction. The third side wall 240 and the fourth side wall 250 extend diagonally upward so that the distance between the third and fourth side walls 240 and 250 gradually increases. In other words, the third side wall 240 is inclined to one side in the X direction (outside the fire bed 200), and the fourth side wall 250 is inclined to the other side in the X direction (outside the fire bed 200).

The flange 260 is a metal (e.g., stainless steel or steel) rectangular frame-shaped plate provided on 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. A pair of screw holes is provided on each of both ends of the flange 260 in the Y direction.

The fire bed 200 described above can be fitted with legs (not shown). Therefore, the fire bed 200 can be used while being supported in midair by the legs. Alternatively, the fire bed 200 can be used while being 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 placed in the fire bed 200. Then, the parts of the bottom plate 110 of the fire bed cover 100 other than the convex portion 111 abut against the bottom plate 210 of the fire bed 200. The third and fourth side walls 140, 150 of the fire bed cover 100 abut against the third and fourth side walls 240, 250 of the fire bed 200. The flange 160 of the fire bed cover 100 is placed on the flange 260 of the fire bed 200. In this way, the fire bed cover 100 is supported by the fire bed 200. At the same time, the first and second side walls 120, 130 of the fire bed cover 100 are arranged opposite the first and second side walls 220, 230 of the fire bed 200 with a gap G. This allows the ventilation hole 121 of the first side wall 120, the gap G, and the ventilation hole 270 of the first side wall 220 to communicate. The ventilation hole 131 of the second side wall 130, the gap G, and the ventilation hole of the second side wall 230 to communicate.

Heating fuel such as charcoal or firewood is placed inside the fire bed cover 100, and the heating fuel is heated. A grill or iron plate (not shown) is placed on the fire bed cover 100 and the fire bed 200. Food can be placed on the grill or iron plate to grill the food.

The fire bed cover 100 and the barbecue grill described above have the following technical features. First, the fire bed 200 can be prevented from being thermally deteriorated by the heating of the heating fuel. The reason is as follows. The fire bed 200 is protected from the heating of the heating fuel by the fire bed cover 100 made of metal foil. The positional relationship between the first and second side walls 120, 130 and the first and second side walls 220, 230 is such that when the fire bed cover 100 is housed in the fire bed 200, a gap G is generated between the first and second side walls 120, 130 and the first and second side walls 220, 230. This gap G functions as air insulation, so the effect of the heating of the heating fuel on the first and second side walls 220, 230 can be reduced. The parts of the bottom plate 110 of the fire bed cover 100 other than the convex portion 111 are in contact with the bottom plate 210 of the fire bed 200, so the effect of heating the heating fuel on the bottom plate 210 can be reduced.

Secondly, it is possible to prevent the fire bed 200 from becoming dirty. This is because the heating fuel is contained within the fire bed cover 100, and oil and other substances from the ingredients fall into the fire bed cover 100, so it is possible to prevent soot, oil, and other substances from adhering to the fire bed 200.

Thirdly, the versatility of the fire bed cover 100 can be improved. This is because even if the fire bed's ventilation holes are not provided at positions corresponding to the ventilation holes 121, 131 of the fire bed cover 100, when the fire bed cover 100 is housed in the fire bed, a gap is created between the first and second side walls 120, 130 and the first and second side walls of the fire bed. 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 fire bed.

Fourthly, the fire bed cover 100 is easy to dispose of. Because the fire bed cover 100 is made of flexible metal foil, 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 inclination angle of the third and fourth side walls 140, 150 of the fire bed cover 100 is approximately the same as the inclination angle of the third and fourth side walls 240, 250 of the fire bed 200, and the third and fourth side walls 140, 150 abut against the third and fourth side walls 240, 250. In addition, the flange 160 of the fire bed cover 100 is supported by the flange 260 of the fire bed 200.

Sixth, the heat dissipation effect of the fire bed cover 100 is improved. This is because the third and fourth side walls 140, 150 have multiple protrusions 141, 151 spaced apart in the Y direction, which increases the surface area of the third and fourth side walls 140, 150.

Seventh, multiple fire bed covers 100 can be stacked one on top of the other. This is because the first and second side walls 120, 130 of the fire bed cover 100 extend diagonally upwards away from each other, and the third and fourth side walls 140, 150 also extend diagonally upwards away from each other.

Next, the fire bed cover 100' according to the second embodiment of the present invention will be described with reference to Figures 3A to 3E. The fire bed cover 100' is a box that can be stored in the fire bed 200' (see Figures 4A to 4B) and is made of flexible metal foil (e.g., aluminum foil). The fire bed cover 100' has the same configuration as the fire bed cover 100, except that the shapes of the first side wall 120', the second side wall 130', the third side wall 140' and the fourth side wall 150' are different from the shapes of the first side wall 120, the second side wall 130, the third side wall 140 and the fourth side wall 150 of the first embodiment. Below, only the differences will be described in detail, and overlapping explanations will be omitted. In addition, the fire bed cover, the first side wall, the second side wall, the third side wall, and the fourth side wall of Example 2 are distinguished from the fire bed cover, the first side wall, the second side wall, the third side wall, and the fourth side wall of Example 1 by adding ' to their reference numbers. The Y direction and the X direction are also shown in Figures 3A and 3C.

The first side wall 120' is a rectangular plate made of metal foil (e.g., aluminum foil) erected on the first end 112 of the bottom plate 110 and extending perpendicularly to the bottom plate 110. The second side wall 130' is a rectangular plate made of metal foil (e.g., aluminum foil) erected on the second end 113 of the bottom plate 110 and extending perpendicularly to the bottom plate 110. The height dimensions of the first and second side walls 120', 130' are slightly larger (by the thickness of the flange 160) than the height dimensions of the first and second side walls 220', 230' (see FIG. 4A) of the fire bed 200' described later. The first and second side walls 120', 130' can abut against the first and second side walls 220', 230' of the fire bed 200'. At the lower end of the first side wall 120', a plurality of ventilation holes 121' are provided at intervals in the X direction, penetrating the first side wall 120'. At the lower end of the second side wall 130', a plurality of ventilation holes 131' are provided at intervals in the X direction, penetrating the second side wall 130'. The ventilation holes 121', 131' can communicate (can vent) with the ventilation holes (see FIG. 4B) of the fire bed 200', which will be described later.

The third side wall 140' is a rectangular plate made of metal foil (e.g., aluminum foil) erected at the third end 114 of the bottom plate 110 and extending perpendicularly to the bottom plate 110. The third side wall 140' connects one end of the first and second side walls 120' and 130' in the X direction. The fourth side wall 150' is a rectangular plate made of metal foil (e.g., aluminum foil) erected at the fourth end 115 of the bottom plate 110 and extending perpendicularly to the bottom plate 110. The fourth side wall 150' connects the other end of the first and second side walls 120' and 130' in the X direction. The height dimensions of the third and fourth side walls 140' and 150' are slightly larger (by the thickness of the flange 160) than the height dimensions of the third and fourth side walls 240' and 250' (see FIG. 4B) of the fire bed 200' described later. The third and fourth side walls 140', 150' are capable of abutting against the third and fourth side walls 240', 250' of the fire bed 200'. The third side wall 140' has convex portions 141' spaced apart in the Y direction. The convex portions 141' are convex toward the inside of the fire bed cover 100' and extend vertically. The fourth side wall 150' has convex portions 151' spaced apart in the Y direction. The convex portions 151' are convex toward the inside of the fire bed cover 100' and extend vertically. The first to fourth side walls 120' to 150' correspond to the side walls in the claims.

The fire bed cover 100' having the above-mentioned configuration is also made of a flexible metal foil (for example, 0.
It is manufactured by press molding aluminum foil (0.035 to 0.06 mm thick) using a mold not shown.

A barbecue grill according to a second embodiment of the present invention will be described below with reference to Figures 4A and 4B. The barbecue grill shown in Figures 4A and 4B includes a fire bed cover 100' and a fire bed 200'. This barbecue grill will be described in detail below.

The fire bed 200' has substantially the same configuration as the fire bed 200 of Example 1, except that the shapes of the first, second, third, and fourth side walls 220', 230', 240', and 250' differ from the shapes of the first, second, third, and fourth side walls 220, 230, 240, and 250 of Example 1. Below, only the differences will be described in detail, and overlapping descriptions will be omitted. Note that the fire bed, first side wall, second side wall, third side wall, and fourth side wall of Example 2 are distinguished from the fire bed, first side wall, second side wall, third side wall, and fourth side wall of Example 1 by adding ' to their reference numbers.

The first side wall 220' is a rectangular metal plate (e.g., stainless steel or steel) erected at the first end 211 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The second side wall 230' is a rectangular metal plate (e.g., stainless steel or steel) erected at the second end 212 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The lower end of the first side wall 220' is provided with an air vent 270' penetrating the first side wall 220'. The lower end of the second side wall 230' is provided with an air vent (not shown) penetrating the second side wall 230'.

The third side wall 240' is a rectangular metal plate (e.g., stainless steel or steel) erected at the third end 213 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The third side wall 240' connects one end of the first and second side walls 220', 230' in the X direction. The fourth side wall 250' is a rectangular metal plate (e.g., stainless steel or steel) erected at the fourth end 214 of the bottom plate 210 and extends perpendicular to the bottom plate 210. The fourth side wall 250' connects the other end of the first and second side walls 220', 230' in the X direction.

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 placed in the fire bed 200'. Then, the parts of the bottom plate 110 of the fire bed cover 100' other than the convex part 111 abut against the bottom plate 210 of the fire bed 200'. The first to fourth side walls 120' to 150' of the fire bed cover 100' abut against the first to fourth side walls 220' to 250' of the fire bed 200', respectively. The flange 160 of the fire bed cover 100' is placed on the flange 260 of the fire bed 200'. In this way, the fire bed cover 100' is supported by the fire bed 200'. The ventilation hole 121' of the first side wall 120' and the ventilation hole 270' of the first side wall 220' are connected. The ventilation hole 131' in the second side wall 130' and the ventilation hole in the second side wall 230' are connected.

Heating fuel such as charcoal or firewood is placed inside the fire bed cover 100' and the heating fuel is heated. A grill or iron plate (not shown) is placed on the fire bed cover 100' and the fire bed 200'. Food can be placed on the grill or iron plate to grill the food.

The fire bed cover 100' and barbecue grill described above have the first to sixth technical features of the fire bed cover 100 and barbecue grill of Example 1.

Next, the fire bed cover 300 according to the third embodiment of the present invention will be described with reference to Figs. 5A to 5C. The fire bed cover 300 shown in Figs. 5A to 5C is a box that can be accommodated in the fire bed 400 (see Figs. 6A to 6C), and is made of flexible metal foil (e.g., aluminum foil). The fire bed cover 300 has a bottom plate 310, a side wall 320, and a flange 330. Each component of the fire bed cover 300 will be described in detail below. Y' shown in Fig. 5B is the radial direction of the side wall 320 of the fire bed cover 300 and indicates the first direction in the claims. X' shown in Fig. 5B is the radial direction of the side wall 320 of the fire bed cover 300 and indicates the second direction in the claims. The X' direction is perpendicular to the Y' direction.

The bottom plate 310 is a circular plate made of metal foil (e.g., aluminum foil). The outer diameter of the bottom plate 310 is smaller than the outer diameter of the bottom plate 410 (see FIG. 6B) of the fire bed 400, which will be described later. The bottom plate 310 is provided with a convex portion (not shown). This convex portion is a protruding vein that protrudes upward. The portion of the bottom plate 310 other than the convex portion can abut against the bottom plate 410 of the fire bed 400. The bottom plate 310 has a ring-shaped end 311.

The side wall 320 is a cylindrical plate made of metal foil (e.g., aluminum foil) erected on the end 311 of the bottom plate 310. The side wall 320 extends obliquely upward so that its outer and inner diameters gradually increase in diameter upward. The largest outer diameter of the side wall 320 is smaller than the inner diameter of the side wall 420 (see FIG. 6B) of the fire bed 400, which will be described later. The height dimension of the side wall 320 is slightly larger (by the thickness of the flange 330) than the height dimension of the side wall 420 of the fire bed 400. The side wall 320 can be arranged opposite the side wall 420 of the fire bed 400 with a gap G'' (see FIGS. 6A and 6C).

The side wall 320 has a first portion 321 on one side in the Y' direction, a second portion 322 on the other side in the Y' direction, a third portion 323 on one side in the X' direction, and a fourth portion 324 on the other side in the X' direction. At least one of the first, second, third, and fourth portions 321, 322, 323, and 324 is provided with an air hole. In this embodiment 3, the first and second portions 321 and 322 are provided with air holes 321a and 322a that penetrate the first and second portions 321 and 322. In the portions of the first, second, third, and fourth portions 321, 322, 323, and 324 where no air holes are provided, a plurality of convex portions or a plurality of concave portions (not shown) are provided at intervals in the circumferential direction of the side wall 320. In this embodiment 3, multiple protrusions are provided at intervals in the circumferential direction of the side wall 320 on the third and fourth sections 323 and 324. These protrusions protrude toward the inside of the fire bed cover 300 and extend in the inclined direction of the side wall 320.

The flange 330 is a ring-shaped plate made of metal foil (e.g., aluminum foil) that is attached to the ring-shaped upper end of the side wall 320 and extends outward.

The fire bed cover 300 having the above-mentioned configuration is made of a flexible metal foil (e.g., 0.0 mm thick).
It is manufactured by press-molding aluminum foil (0.35 to 0.06 mm thick) using a mold not shown.

The barbecue grill according to the third embodiment of the present invention will be described below with reference to Figures 6A to 6C. The barbecue grill shown in Figures 6A to 6C includes a fire bed cover 300 and a fire bed 400. This barbecue grill will be described in detail below.

The fire bed 400 is a metal (e.g., stainless steel or steel) box capable of housing the fire bed cover 300. The fire bed 400 has a bottom plate 410, side walls 420, and a flange 430.

The bottom plate 410 is a circular plate made of metal (e.g., stainless steel or steel).

The side wall 420 is a metal (e.g., stainless steel or steel) cylinder erected on the ring-shaped end of the bottom plate 410. The side wall 320 extends perpendicularly to the bottom plate 410. The side wall 420 has a first portion 421 on one side in the Y' direction, a second portion 422 on the other side in the Y' direction, a third portion 423 on one side in the X' direction, and a fourth portion 424 on the other side in the X' direction. At least one of the first, second, third, and fourth portions 421, 422, 423, and 424 is provided with an air hole. In this embodiment 3, the first and second portions 421 and 422 are provided with an air hole 425 that penetrates the first and second portions 421 and 422.

The flange 430 is a ring-shaped plate made of metal (e.g., stainless steel or steel) that is attached to the ring-shaped upper end of the side wall 420 and extends outward.

The fire bed 400 described above can be fitted with legs (not shown). Therefore, the fire bed 400 can be used while being supported in midair by the legs. Alternatively, the fire bed 400 can be used while being placed directly on a table or the like.

The procedure for attaching the fire bed cover 300 to the fire bed 400 will be described below. First, the fire bed cover 300 is placed in the fire bed 400. Then, the parts of the bottom plate 310 of the fire bed cover 300 other than the convex parts come into contact with the bottom plate 410 of the fire bed 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 fire bed cover 300 is disposed opposite the side wall 420 of the fire bed 400 with a gap G''. This allows the ventilation holes 321a, 322a, the gap G'' of the side wall 320, and the ventilation hole 425 of the side wall 420 to communicate.

Heating fuel such as charcoal or firewood is placed inside the fire bed cover 300, and the heating fuel is heated. A grill or iron plate (not shown) is placed on the fire bed cover 300 and the fire bed 400. Food can be placed on the grill or iron plate to grill the food.

The fire bed cover 300 and the barbecue grill described above have the following technical features. First, the fire bed 400 can be prevented from being thermally deteriorated by the heating of the heating fuel. The reasons are as follows. The fire bed 400 is protected from the heating of the heating fuel by the fire bed cover 300 made of metal foil. The positional relationship between the side walls 320 and 420 is such that a gap G'' is created between the side walls 320 and 420 when the fire bed cover 300 is housed in the fire bed 400. This gap G'' functions as air insulation, so the effect of the heating of the heating fuel on the side walls 420 can be reduced. The parts of the bottom plate 310 of the fire bed cover 300 other than the convex parts are in contact with the bottom plate 410 of the fire bed 400, so the effect of the heating of the heating fuel on the bottom plate 410 can be reduced.

Secondly, it is possible to prevent the fire bed 400 from becoming dirty. This is because the heating fuel is placed inside the fire bed cover 300, and oil and other substances from the ingredients fall into the fire bed cover 300, so it is possible to prevent soot, oil, and other substances from adhering to the fire bed 400.

Thirdly, the versatility of the fire bed cover 300 can be improved. This is because even if the fire bed's ventilation holes are not provided at positions corresponding to the ventilation holes 321a, 322a of the fire bed cover 300, when the fire bed cover 300 is housed in the fire bed, a gap is created between the side wall 320 and the side wall of the fire bed. This gap allows the ventilation holes 321a, 322a of the side wall 320 to communicate with the ventilation holes of the side wall of the fire bed.

Fourthly, the fire bed cover 300 is easy to dispose of. Because the fire bed cover 300 is made of flexible metal foil, it can be rolled up and thrown away.

Fifth, the fire bed cover 300 is stably supported by the fire bed 400 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 bed cover 300 is improved. This is because the third and fourth parts 323 and 324 of the side wall 320 have multiple protrusions spaced apart in the circumferential direction, which increases the surface area of the side wall 320.

Seventh, multiple fire bed covers 300 can be stacked one on top of the other.
This is because the outer and inner diameters of the side wall 320 of the fire bed cover 300 gradually increase in diameter upward.

The fire bed cover and barbecue grill described above are not limited to the above examples, and can be modified in any way within the scope of the claims. This is described in more detail below.

The fire bed cover of the present invention is a box that can be contained within the fire bed, and as long as it is made of flexible metal foil, the design can be modified as desired.

The shape of the bottom plate of the fire bed cover of the present invention can be arbitrarily modified. For example, the bottom plate of the fire bed cover can be polygonal. The side walls of the fire bed cover of the present invention can be arbitrarily modified as long as they are erected at the ends of the bottom plate. For example, the side walls can be erected at the ends of each side of the polygonal bottom plate. Each side wall of the above embodiment and the above-mentioned design modification example can be modified in design to a shape extending diagonally upward outside the fire bed cover, a vertical shape, or a shape extending diagonally upward inside the fire bed cover. For example, at least one of the first side wall 120, the second side wall 130, the third side wall 140, and the fourth side wall 150 can be modified in design to a shape extending vertically or diagonally upward inside the fire bed cover. The side wall 320 can be vertical or shaped to extend diagonally upward inside the fire bed cover (a shape in which the outer diameter and inner diameter gradually decrease upward).

The side wall of the fire bed cover of the present invention can be configured so that its entire area contacts the inner surface of the side wall of the fire bed of the barbecue grill. In addition, the side wall of the fire bed cover of the present invention can be configured so that at least a part of the side wall can be arranged to face the side wall of the fire bed with a gap. For example, the first and second side walls 120', 130' of the fire bed 200' can be arranged to face the first and second side walls 220', 230' of the fire bed 200' with a gap. Only the first side wall of the fire bed cover can be arranged to face the first side wall of the fire bed with a gap. Only the third side wall of the fire bed cover can be arranged to face the third side wall of the fire bed with a gap. It is possible to configure the third side wall of the fire bed cover to be arranged to face the third side wall of the fire bed with a gap, and the fourth side wall of the fire bed cover to be arranged to face the fourth side wall of the fire bed with a gap.

It is possible to configure a portion of the side wall 320 so that it can be arranged to face the side wall 420 of the fire bed 400 with a gap. For example, it is possible to configure the first and second parts 321, 322 of the side wall 320 so that they can be arranged to face the first and second parts 421, 422 of the side wall 420 with a gap, and the third and fourth parts 323, 324 can abut against the third and fourth parts 423, 424 of the side wall 420. It is possible to configure the third and fourth parts 323, 324 of the side wall 320 so that they can be arranged to face the third and fourth parts 423, 424 of the side wall 420 with a gap, and the first and second parts 321, 322 can abut against the first and second parts 421, 422 of the side wall 420. Any one of the first, second, third, and fourth parts 321, 322, 323, and 324 of the side wall 320 can be arranged to face any one of the first, second, third, and fourth parts 421, 422, 423, and 424 of the side wall 420 with a gap therebetween, and the remaining first, second, third, and fourth parts 321, 322, 323, and 324 can abut the remaining first, second, third, and fourth parts 421, 422, 423, and 424 of the side wall 420. The side wall 320 can be abutted against the side wall 420. Note that a part of the side wall described above can be bent, and the side wall can have a step.
