Description

The present invention relates to a stone oven assembly kit and an assembly type stone oven.

Conventionally, stone ovens using refractory bricks and processed natural stones have been known (for example, Patent Document 1 and the like). By cooking firewood inside such a stone oven and storing heat, it is possible to bake full-scale bread and pizza. In addition, the stone oven has been devised in various materials and structures from the viewpoint of thermal efficiency and durability, and in general, it is a skillful technique to construct a heavy stone oven with excellent thermal efficiency and durability. It takes construction time.

On the other hand, with the growing tendency toward outdoor activities in recent years, many simple stone oven assembly kits that can be assembled and installed relatively easily at home have also been proposed.

In the stone oven assembly kit currently on the market, for example, as illustrated in the perspective view of FIG. 4 (1), a prismatic refractory brick having a rectangular cross section is piled up on a base to form a side wall, and the same applies on the side wall. Some roofs are made of prismatic refractory bricks. Here, the roof of the stone oven is formed in an arch shape from the viewpoint of thermal efficiency, but since there is a gap between the refractory bricks, as shown in the cross-sectional views of FIGS. 4 (1) and 4 (2). In addition, the gap is filled with refractory mortar X to stabilize the structure of the stone oven and suppress heat outflow from the stone oven.

However, as described above, in the stone oven assembly kit in which the gap between the refractory bricks is filled with refractory mortar to assemble the stone oven, the assembly work is complicated and the disassembly of the stone oven after assembly is difficult. There is a problem. In addition, since ash is scattered inside and around the stone oven due to the use of the stone oven, there is also a problem that it takes time and effort to clean the assembled stone oven.

In a general household, it is often difficult to secure a space for permanently installing a stone oven outdoors, so a stone oven assembly kit having the above-mentioned problem does not necessarily stimulate consumers' purchasing motivation. It's hard to say that there is. That is, it is considered that a stone oven assembly kit that can be easily assembled when necessary and can be disassembled and put away again after use is desired. Moreover, if it is such a stone oven assembly kit, it is considered that cleaning after using the stone oven is easy.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stone oven assembly kit and a stone oven that can be easily assembled when necessary and can be disassembled again after use. ..

The present invention is a stone kiln assembly kit for producing an arch-shaped stone kiln in order to solve the above-mentioned problems. It is a prismatic fireproof block having an isosceles trapezoidal cross section, along the circumference of the arch shape. Each of the fireproof blocks for stacking from the left and right along the circumference of the arch, including the ones for stacking from the left and right and the ones arranged on the top of the arch, with the short side of the bottom of the trapezoid on the inside. The slopes of the fireproof blocks are brought into contact with each other and stacked, and then the fireproof blocks to be placed on the top of the arch are placed in the gap between the tops of the arch with the short side of the bottom of the trapezoid on the inside to stand in an arch shape. We provide a stone kiln assembly kit characterized by being able to be installed.

The present invention also provides an assembling type stone oven assembled by the above-mentioned stone oven assembling kit.

According to the present invention, the stone oven can be easily assembled when necessary, and the stone oven can be easily disassembled again after use.

It is a front view (left) and a side view (right) which exemplify two kinds of refractory blocks (A) (B) which constitute a stone oven assembly kit as one embodiment of the present invention. It is a front view of a stone oven as an example assembled by the stone oven assembly kit of this invention. It is a schematic diagram which illustrated the method of assembling a stone oven using a template. (1) is a perspective view of a conventional prefabricated stone oven, and (2) is a cross-sectional view of a conventional prefabricated stone oven.

FIG. 1 is a front view (left) and a side view (right) illustrating two types of refractory blocks (A) and (B) constituting a stone oven assembly kit as an embodiment of the present invention. FIG. 2 is a front view illustrating a stone oven assembled by the stone oven assembly kit of the present invention.
In the examples of FIGS. 1 and 2, the refractory blocks (A) have the same shape and are stacked from the left and right along the arch-shaped circumference, and a plurality of them are used. The refractory block (B) is a refractory block arranged on the top of the arch shape.

The material of the refractory block of the stone oven assembly kit of the present invention can be appropriately selected in consideration of heat resistance, durability and the like. It is preferably a refractory brick, and for example, a refractory brick having a refractory temperature of about 1000 ° C. can be preferably exemplified.

The refractory blocks (A) and (B) are all prismatic with an isosceles trapezoidal cross section. An isosceles trapezoid is a trapezoid in which the length of a pair of hypotenuses is the same and the angle between the base (upper base, lower base) and the pair of hypotenuses is the same. In the present invention, as illustrated in FIGS. 1A and 1B, the base having a long length is defined as the upper base a and the base having a short length is defined as the lower base b. In the refractory block (B) inserted and arranged on the arch, the dimension of the lower base b is set smaller than that of the refractory block (A) in this example.

As illustrated in FIG. 2, in the stone oven assembly kit of the present invention, the slopes of the refractory block are brought into contact with each other so that the trapezoidal bottom b of the cross section of the refractory block is located inside, and the plurality of refractory blocks having the same shape are brought into contact with each other. The refractory blocks (A) are stacked from the left and right along the arch-shaped circumference. Next, at the top of the arch, the refractory block (B) is inserted and placed in the gap at the top of the stacked refractory blocks (A). As a result, each refractory block is supported by adjacent left and right refractory blocks, and an arch-shaped stone oven that is mechanically stable as a whole can be erected. Since the stone oven has an arch shape, the heat and flame inside the stone oven wind up along the curved surface of the arch, so that uniform radiant heat can be generated.
The refractory blocks (A) to be stacked along the circumference of the arch may be of the same size and shape as described above, or may be stacked using a plurality of types having different dimensions, for example, two types. You may do so.
Further, the number of fireproof blocks (B) arranged on the top of the arch shape may be one, but may be plural. The dimensions and number of refractory blocks (A) and (B) are designed as described above so that a semicircular arch is formed. Various arch shapes can be formed by designing the dimensions, number, and arrangement of refractory blocks.

In the stone oven assembly kit of the present invention, it is preferable to design the shape and combination of the refractory blocks so that the lower surfaces of the two refractory blocks (A) at the arch ends that come into contact with the ground are located on the same plane. As a result, the stone oven can be stably assembled on a flat ground.

When assembling the stone oven using the stone oven assembly kit of the present invention, for example, a template corresponding to the arch shape of the stone oven after assembly can be appropriately used.

Specifically, as illustrated in the schematic view of FIG. 3, a substantially semicircular template Y corresponding to the arch shape of the stone oven is erected at the position where the stone oven is assembled, and the refractory block (A) is attached to the template Y. Set on the ground at both ends. Then, the refractory blocks (A) are stacked along the outer circumference of the semicircular template Y from the refractory blocks, and the refractory blocks (B) are inserted and arranged at the top to form a single row of arches. it can. Since the stone oven after assembly is mechanically stable, the template Y can be taken out after the stone oven is assembled. As described above, the stone oven assembly kit of the present invention may include a template Y used when assembling the stone oven. The material of the template Y may be any material that can withstand the weight of the refractory block, and plywood, cardboard, and the like can be appropriately used.

Further, in the stone oven assembled by the stone oven assembly kit of the present invention, since the slopes M of the refractory blocks are in surface contact with each other, there is almost no gap between the refractory blocks. Therefore, the heat inside the stone oven is unlikely to flow out, and the temperature inside the stone oven can be preferably maintained. Therefore, it is not necessary to take measures to suppress heat outflow such as the use of refractory mortar.
The dimensions and arrangement of the refractory blocks can be appropriately designed according to the shape and size of the arches of the stone oven, but in order to secure the depth of the stone oven, the arches of the refractory blocks are arranged in parallel in the depth direction. be able to. By adjusting the number of arches to be paralleled, the depth dimension of the stone oven can be designed. Of course, a refractory block having a predetermined length in the depth direction can also be used.

In addition, a tunnel-shaped internal space is formed in the depth direction of the stone oven erected in an arch shape. Therefore, in order to store heat in the stone oven, it is necessary to cover the tunnel-shaped internal space from the back side. Therefore, the stone oven assembly kit of the present invention can include a refractory material (not shown) for covering the tunnel-shaped interior space. The refractory material may be of various materials such as a plate-shaped member, and for example, rectangular parallelepiped refractory blocks can be stacked to cover the back surface of the stone oven.

The stone oven assembly kit of the present invention can be assembled directly on a flat ground outdoors, but since the soil contains moisture, it may be difficult for the temperature inside the stone oven to rise due to the heat of vaporization. .. In such a case, in order to shorten the preheating time, for example, a rectangular parallelepiped refractory block can be laid flat on the ground, and a stone oven can be assembled on the block. Therefore, the stone oven assembly kit of the present invention can include a refractory block (not shown) for the base.

As described above, the stone oven assembly kit of the present invention can stably assemble an arch-shaped stone oven without using a refractory mortar or the like. Therefore, even in an environment where the space for installing the stone oven cannot be secured constantly, it can be easily assembled when necessary, and the stone oven can be disassembled again after use. In addition, since the used stone oven can be easily disassembled, it is possible to easily clean the ash and the like scattered inside and around the stone oven by using the stone oven. In addition, since there is almost no gap between the refractory blocks, the heat inside the stone oven does not easily flow out, and it is possible to maintain a sufficient temperature for cooking bread, pizza, naan, and roasted potatoes.

The present invention is not limited to the above-mentioned form, and the design can be changed as appropriate for details. For example, the dimensions, number, and the like of the refractory blocks can be appropriately determined according to the height and depth dimensions of the arch of the stone oven. In addition, the stone oven assembly kit of the present invention may include a spare refractory block in case of breakage or deterioration.
