Description

[Detailed description of the invention] [Field of industrial application] The present invention is a grill for grilling fish, meat, etc., in which a plurality of meshes are formed on a plate material by means such as punching or punching. Regarding the grill.

[Conventional technology]

Conventionally, as shown in FIG. 15, in the above-mentioned grill, the plate portion 2b' located between the adjacent meshes 2a' is the result of processing such as punching or punching.
It is known that it is gently curved (I can't cite any literature).

[The problem that the idea aims to solve]

However, with the above-mentioned conventional grill, when it heats and thermally expands as fish, meat, etc. are grilled, the plate portions between adjacent meshes simply bend as a result of processing. Since the expansion was gradual, the thermal stress generated by thermal expansion was transmitted almost evenly from one end of the plate to the other, causing the plate to elongate almost evenly in the longitudinal direction, causing local heating. When this occurs, the thermal stress is accumulated in a relatively large area containing multiple meshes and becomes a large force, and as a result, the grille receives reaction force from the surrounding areas that are not heated and have little elongation. was largely deformed in the out-of-plane direction, resulting in waving.

In view of the above-mentioned circumstances, an object of the present invention is to provide a grill that is less likely to undergo large deformations such as waving.

[Means to solve the problem]

A characteristic feature of the grill according to the present invention is that bent protrusions are formed in the plate portions located between adjacent meshes.

[Effect]

In other words, when fish or meat is heated and thermally expanded as it is grilled, a protruding portion is formed by bending the plate portion located between adjacent meshes.
Thermal stress generated by thermal expansion concentrates on the bending protrusion and acts mainly to further bend the bending protrusion in the bending direction, and the thermal stress is applied from one end of the plate section to the other end. , and there is less elongation between the ends of the plate section. Therefore, even in a relatively large area including a plurality of meshes, there is no accumulation of thermal stress due to the longitudinal elongation of the heated plate portion.

[Effect of idea]

As a result, the thermal stress generated when heated and thermally expanded is used as a force to deform the bent protrusion formed in the vicinity of each mesh, and the thermal stress is accumulated to create a large force. Since this can be avoided, the reaction force from the parts around the heated part that are not heated and hardly elongate is also reduced, and the grille is less likely to be greatly deformed in an out-of-plane direction and cause ripples. can.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 6, a first net 2 for heat diffusion is held at the bottom of the frame 1, and a second net 3 for placing fish is provided at the top of the frame 1. Handle 4 at one end
is extended to form a fish fryer.

As shown in FIG. 2, the first net 2 is constructed by applying a ceramic coating 2B mainly made of gypsum to a net main body 2A, which is a gridiron according to the present invention.

As shown in FIG. 1, the net main body 2A is formed by forming a plurality of meshes 2a on a plate material in a staggered arrangement, and as shown in FIG.
and a receiving mold 6. First, the punching blade 5 is brought into contact with the plate material 7 from an oblique direction and pressed, and the receiving mold 6 receives the punched blade 5, thereby separating the cutting edge 5a of the punching blade 5 and the cutting edge 6a of the receiving mold 6. The plate material 7 is broken diagonally to form a row of meshes 2a, and then both the punching blade 5 and the receiving mold 6 are moved in the X direction in FIG. 5 by an amount corresponding to their width. , by shifting the mesh 2a in the Y direction in FIG. 5 by an amount corresponding to half the longitudinal length of the mesh 2a, and pressing the plate material 7 from the diagonal direction with the punching blade 5 in the same manner as described above. It is formed by forming meshes 2a in rows of and sequentially repeating this operation, and
When viewed in cross-section along the direction, they exhibit the cross-sectional shapes shown in FIGS. 3 and 4, respectively.

In this net main body 2A, as shown in FIGS. 1, 3 to 5, a pair of bent protrusions S,
2c and 2d are formed. The formation of the bent protrusions S, 2c, and 2d is performed simultaneously with the mesh 2a forming operation using the punching blade 5 and the receiving mold 6, as shown in FIG. It has become a position that stands out. The pair of bent protrusions S, 2c, and 2d are such that one 2c is the other 2d.
A small hole 2e is formed between the pair of bent protrusions S, 2c, and 2d by having different punching depths.

These pair of bent protrusions S, 2c,
2d is formed on the plate portion 2b located between the adjacent meshes 2a, so that when the fish is heated and thermally expanded when grilling fish using this fish griller, the thermal expansion is prevented. The thermal stress generated in the plate is concentrated on the bending protrusions S, 2c, 2d and acts to further bend the bending protrusions S, 2c, 2d in the bending direction. part 2
It is possible to avoid deformation such as waving of the gridiron due to the accumulation of thermal stress in a large area including a plurality of meshes by preventing the heat stress from being completely transmitted from one end of the grid to the other end.

[Another example]

Next, another embodiment of the present invention will be listed.

<1> In the previous embodiment, a pair of bent protrusions S, 2c, and 2d were formed on the plate portion 2b located between the adjacent meshes 2a, but
The number of bent protrusions S to be provided does not matter, and the plate portion 2
Only one or three or more may be provided in each of the length direction and the width direction of b. Further, the bent protruding portions S do not need to be provided on all the plate portions 2b, and may be provided on every other plate portion, for example. Furthermore, in the previous embodiment, mesh 2
Since the mesh 2 a is formed in an elongated shape, the mesh 2 that is adjacent to the mesh 2 a in the width direction has a large expansion amount.
The bent protruding portion S was provided only on the plate portion 2b between the sections a, but for example, the mesh 2a may be approximately circular as shown in FIG. 7, or the mesh 2a may be square as shown in FIG. 8, 9 and 11, respectively.
As shown in FIG. 12, adjacent meshes 2a
The bent protruding portion S may be formed in all of the plate portions 2b between them.

<2> The bending direction of the bent protruding portion S is arbitrary,
Instead of the diagonally bent posture described in the previous embodiment,
As shown in Figs.
As shown in the figures to FIG. 14, the plate may be bent in the in-plane direction.In short, it is sufficient that the plate portion 2b is bent in the direction of bending in response to the axial force from both ends of the plate. .

<3> Instead of forming the mesh 2a by punching as explained in the previous embodiment, it may be formed by punching or by stretching a plate with cuts. Further, the formation of the bent protruding portions S may be performed in a separate step from the formation of the mesh 2a.

<4> In the previous embodiment, a fish fryer was explained in which the grill according to the present invention was applied as a net for dispersing heat from a heat source. It may also be used to hold fish or meat. Furthermore, instead of applying ceramic coating, plating may be applied, or depending on the type of material, the material may be used as is.
