The windbreak furnace 70 comprises a pair of windbreak frames 1, 1,
It comprises at least one auxiliary windbreak plate 71, 73. Side edge (front edge) 22 of windshield 2 at one end of windshield 1
3, engagement grooves 23 and 25 are formed. Engagement grooves 63 and 65 are formed in the side edge (rear edge) 61 of the windproof plate 5 at the other end of the windproof frame 1.

The upper auxiliary windbreak plate 71 is formed by joining the bent upper edge 72 to the windbreak plates 2, 5
And is detachably attached to the pair of opposing windproof frames 1, 1. The lower auxiliary windshield 73 engages the bent upper edge 74 with the engagement grooves 25 and 65 of the windshields 2 and 5 of the pair of opposed windshield frames 1 and 1, and the pair of opposed windshields 73. Is detachably attached to the windproof frames 1, 1.

The auxiliary windshields 71 and 73 are formed with a pair of finger holes 75 and 76, and use the finger holes 75 and 76 to facilitate attachment and detachment. Further, at the upper end of the upper auxiliary windbreak plate 71, there are formed two support concave portions 77 for supporting the rod 17 immovably.

When the auxiliary wind shields 71 and 73 are provided on one of the pair of wind shield frames 1 and 1 facing each other, the windbreak furnace 70 becomes a substantially U-shaped furnace and has a pair of wind shield frames 1 and 1 facing each other. When the auxiliary windbreak plates 71 and 73 are provided in both (see FIGS. 1 and 2), the furnace becomes a substantially square-shaped furnace. The auxiliary windbreak plates 71, 7
3 is composed of two sheets, but can be reduced to one sheet by extending the auxiliary windshield 71 downward.

In the windbreak furnace 70, since the windbreak frames 1, 1 and the auxiliary windbreak plates 71, 73 prevent wind, even if a bonfire is fired in the center surrounded by the windbreak furnaces 70, the blowout and the sparks are less likely to be scattered. In addition, each windproof plate 2-5 of the windproof frame 1
Are formed with vents 12, 33, 43, 53, but the wind passing through the vents 12, 33, 43, 53 is not directly sent to the bonfire side, but as shown in FIG. The air is temporarily sent to the hinge connection portion side by the wind direction members 13, 35, 45, and 55, and then goes to the bonfire side, so that the wind is weakened and the bonfire is not blown off. The windbreak furnace 70 can correspond to various heating means such as a charcoal fire and a gas stove in addition to the bonfire.

The windbreak furnace 70 includes the support recesses 19 of the windbreak plate 2 and the support recess 59 of the windbreak plate 5 facing each other, the support recess 39 of the windbreak plate 3 and the support recess 49 of the windbreak plate 4 facing each other with rods 17.
Is placed on this stick 17 ...
You can cook rice, make pork juice, curry, and barbecue by placing a pot, a kettle, an iron plate, and a wire mesh. Further, the supporting recesses 19, 39, 4
9, 59 and 77 also serve as a blow-through of the fire in the windbreak furnace 70. In addition, as shown in FIGS.
3, the windbreak furnace can be constituted only by the windbreak frames 1 and 1.

In the windbreak furnace 70, the windbreak frame 1 can be compactly folded as shown in FIG. 4 by removing the auxiliary windbreak plates 71 and 73, so that the windbreak furnace 70 is convenient to carry and easy to store. In addition, the wind direction members 13 of the wind shield 2 and the wind direction members 35 of the wind shield 3 do not overlap each other, and the wind direction members 45 of the wind shield 4 and the wind direction members 35 of the wind shield 3 do not overlap each other. Similarly, since the wind direction member 45 of the windbreak plate 4 and the wind direction member 55 of the windbreak plate 5 are staggered and do not overlap, they can be folded without being bulky. Further, the windbreak furnace 70 is provided with a state of the ground to be grounded, a heating means such as a bonfire,
It can be assembled in different shapes and sizes according to cooking utensils such as iron plates and iron nets.

[0037]

As described above, the first aspect of the present invention is as follows.
The windbreak frame described includes a plurality of windbreak plates hinged in a folding screen shape, and a fixed shaft that is inserted through each windbreak plate and holds a wavy bent state, and stably stands on the ground. In addition to the above, when the fixed shaft is removed, a plurality of windbreak plates can be folded compactly, which is convenient to carry and easy to store. In addition, since each windbreak plate is individually rotated, the size and shape can be changed, and there is an effect that a windbreak furnace can be formed according to a grounding environment, heating means, and cooking utensils. Further, since the structure is simple, there is an effect that it can be manufactured at low cost.

[0038] In the windproof frame according to the second aspect of the present invention, a locking portion for locking the bent end of the fixed shaft is formed on the windproof plate at at least one end, in addition to the insertion portion for inserting the fixed shaft. Therefore, in addition to the above-described effects, there is an effect that the wave-like bent state can be more reliably maintained.

In the windproof frame according to the third aspect of the present invention, a vent is formed through the windproof plate, and a wind direction member for changing the direction of the wind entering through the vent is provided. In addition to the above effects, the ventilation inside the windbreak furnace formed by the windbreak plate is improved, and the fire in the windbreak furnace is not directly hit by the wind, so that the fire is not extinguished or the sparks are not blown. There is.

In the windproof frame according to the fourth aspect of the present invention, a support recess for supporting the rod immovably is formed at the upper edge of at least one windproof plate. It is possible to cook rice by putting it on or putting it on it, boil water by placing a kettle, a pot, etc., and barbecue by placing an iron plate, a net, etc., and the support recess also becomes a fire blow-through effective.

The windproof furnace according to the fifth aspect of the present invention comprises the pair of windproof frames and at least one auxiliary windproof plate removably attached to the pair of windproof frames. There is an effect that the frame can be folded compactly, which is convenient to carry and easy to store. In addition, since each windbreak plate rotates individually, there is an effect that the windshield can be assembled in a size and shape suitable for an environment to be grounded, a heating means to be used, a cooking utensil such as an iron plate, and an object to be heated such as a rice cooker.
