It has been extended to. On the other hand, the connecting portion 21 of the first housing plate portion 11 is formed from the upper end of the long side 11A, and the protruding portion 31B extends downward. With this structure, the first housing plate portion 11 is placed and supported on the second housing plate portion 12 via both base portions 21A and 31A. Then, the protrusion 31B of the second housing plate 12 is hooked on the first housing plate 11 or the base 21A, and the protrusion 21B of the first housing plate 11 is second. By being hooked on the housing plate portion 12 or the base portion 31A, the hinge connection state between the first housing plate portion 11 and the second housing plate portion 12 is realized.

That is, on the rear side of the assembled stove 10, the hinge connecting portions 21 are not connected in the entire regions of the long side sides 11A and 12A, but in the forming regions of the hinge connecting portions 21 and 31 at the six locations. 31 are connected to each other. Then, the length L4 of the gap 30 of the first housing plate portion 11 (see FIG. 2A) and the length L24 of the gap of the second housing plate portion 12 (see FIG. 2B) are It is about twice the thickness of the first housing plate portion 11 and the second housing plate portion 12, and has a space as a clearance.

With this structure, even if the first housing plate portion 11 and the second housing plate portion 12 are slightly warped due to the heat of combustion, the hinge connecting portions 21 and 31 can be easily assembled to each other and have a thickness of about 10 mm. Since the hooks of both protrusions 21B and 31B can be easily removed, the structure does not affect the ease of assembling and disassembling. Further, it is possible to adjust the size of the front opening portion by the first housing plate portion 11 and the second housing plate portion 12 by rotating at the hinge connecting portions 21 and 31 due to the clearance provided by both gaps 30 and 40. Even if the third housing plate portion 13 is slightly warped, the third housing plate portion 13 can be easily changed to the first housing plate portion 11 and the second housing plate portion according to the amount of the warp. It can be assembled to 12.

It has a pull-out prevention portion 41B protruding to the side. The length L44 of the gap between the disconnection prevention portion 41B and the long side sides 13A and 13B is, for example, 6 mm. Further, the plate thickness of the first housing plate portion 11 and the second housing plate portion 12 is, for example, 3.2 mm.

With this structure, when the locking portion 41 is inserted into the locking holes 22 and 32, the warp adjusting portion 41A is the warp of the first housing plate portion 11 and the second housing plate portion 12. The width of the clearance is about 3 mm.

For example, when the first housing plate portion 11 has a warp characteristic toward the inside of the combustion space 14, the first housing plate portion 11 has a direction in which the substantially V-shaped cross section closes due to the heat of combustion. Although the warp is about 3 mm, the first housing plate portion 11 hits the third housing plate portion 13 to prevent further warpage. On the other hand, when the second housing plate portion 12 has a warp characteristic toward the outside of the combustion space 14, the second housing plate portion 12 has a substantially V-shaped cross section in the direction of opening due to the heat of combustion. Although it warps by about 3 mm, further warpage can be prevented by the second housing plate portion 12 hitting the disconnection prevention portion 41B.

That is, the first housing plate portion 11 and the second housing plate portion 12 are warped due to the heat of combustion, but the structure regulates the amount of warpage by connecting them via the third housing plate portion 13. It has become. Even if the first housing plate portion 11 and the second housing plate portion 12 are slightly warped due to the heat of combustion, the clearance width can be used to cope with the structure, which does not easily affect the assembling property and disassembling property. It has become.

Similarly, in the third housing plate portion 13, the opening lengths L7 (see FIG. 2A) and L27 (see FIG. 2B) of the locking holes 22 and 32 in the lateral direction are similarly formed. It is 6 mm, has a clearance width against warpage, and has a structure in which the amount of warpage is regulated by the first housing plate portion 11 and the second housing plate portion 12. Further, the third housing plate portion 13 is arranged so as to be offset inside the first housing plate portion 11 and the second housing plate portion 12, and the first housing plate portion 11 and the second housing plate portion 12 are arranged. The structure is such that warpage is easily regulated by the housing plate portion 12 of 2.

Further, the separation lengths L2 and L22 between the hinge connecting portions 21 and 31 are 75 mm, the separation lengths L6 and L26 between the locking holes 22 and 32 are 115 mm, and the hinge connecting portions 21 and 31 have the hinge connecting portions 21 and 31. It is arranged at a narrower pitch than the locking portion 41. The first housing plate portion 11 and the second housing plate portion 12 are slightly warped due to the heat of combustion, but as shown in FIG. 4B, the hinge connecting portions 21 and 31 are connected to each other and the hinges are hinged. When the connecting portions 21 and 31 come into contact with the first housing plate portion 11 and the second housing plate portion 12, the structure is such that the amount of warpage is regulated to each other. On the other hand, as described above, the locking holes 22 and 32 have a clearance width of about 3 mm with respect to the warp of the first housing plate portion 11 and the second housing plate portion 12.

Due to this structure, when the first housing plate portion 11 and the second housing plate portion 12 are slightly warped, the hinge connecting portions 21 and 31 are more engaged than the long side sides 11A and 12A on which the hinge connecting portions 21 and 31 are formed. By positively warping the long side sides 11B and 12B on which the stop holes 22 and 32 are formed, the warp on the hinge connecting portions 21 and 31 can be suppressed. By realizing the ease of assembling and disassembling the hinge connecting portions 21 and 31 having many connecting points, the ease of assembling and disassembling the entire assembled stove 10 is realized and assembled. Repeated use of the formula stove 10 can be realized.

Even if the amount of warpage of the first housing plate portion 11 or the like becomes large due to the repeated use of the assembled stove 10, the structure of the first housing plate portion 11 or the like is a plate-like body having a simple shape. It can be easily repaired by hitting it with a hammer or the like.

Next, a structure in which the first housing plate portion 11, the second housing plate portion 12, the third housing plate portion 13, and the bottom plate portion 15 prevent warpage due to combustion heat will be described.
