Description

  The present invention is a network structure for a pizza kiln for separating fuel such as firewood or charcoal that burns on the hearth surface of a pizza kiln.

  About the pizza kiln which burns fuel, such as firewood or charcoal, on a hearth surface, and heats and bake a pizza, as shown in patent documents 1 thru / or 3, for example, a thing for large households for business to a thing for small households Until now, various shapes and structures have been proposed.

  For example, a home-made dome-shaped pizza kiln has a self-made pizza kiln kit designed so that anyone can easily make a round pizza kiln. A beautiful round pizza kiln can be completed simply by arranging fire bricks in order along the formwork. Refractory bricks that have been processed with firm accuracy are also being offered. There is also a structure in which the flames circulate evenly over the round ceiling, so it is very quick from the start of the fire to the end of the fire, and the thermal efficiency is improved from pizza to baking.

  In addition, what is essential for cooking in a stone kiln (pizza kiln) is fuel. It is common to use firewood as fuel for stone kilns, but firewood used for stone kilns is used to heat food, unlike firewood used for firewood stoves. Basically, using solid wood. Hardwood is the basic type of firewood used in stone kiln (pizza kiln) cooking. In residential areas, smoke from stone kilns can be annoying. In such cases, charcoal is used as fuel. Charcoal has less firepower than firewood, but it produces little smoke and is easy to obtain. When charcoal is used as fuel, the combustion time is longer than that of soot. In addition to charcoal, Oga charcoal can also be used as fuel. It is characterized by good fire and little smoke.

  As a general usage example of the usage method of a pizza kiln, first, charcoal, firewood, or solid pellets are placed on the center floor of the hearth, ignited, and the burned ones are stacked. Measure the temperature of the hearth of the pizza kiln. When the temperature is suitable for baking (for example, 350 ° C. or higher), in order to create a space for baking pizza, charcoal or firewood is brought near the left or right wall to create a space on the center floor. Using a brush with a handle, sweep the fine ash on the floor in the center, and wipe off the ash as much as possible with a wet cloth. Then, the pizza is inserted into the hearth with a pizza peel or the like and placed, and baking is started. After baking, take out the pizza with a pizza peel. Remove the ash from the hearth with an ash scraper and clean it.

  However, when baking pizza in the hearth, the hearth temperature must be elevated. Normally, the temperature of the hearth is raised by the overall thermal convection, but it takes some time. In addition, as described above, the baking of pizza has a problem that the operation of moving or cleaning the fuel such as firewood or charcoal is complicated and hinders the improvement of work efficiency. Also, if you want to increase the thermal power, you will try to stack a large amount of fuel like a mountain and burn it, but there is a problem of taking up space, and the mountain collapses, eventually increasing the thermal power There was a limit to this. Furthermore, when using charcoal to avoid smoke generated by soot, there is a problem that the thermal power is weak.

  A plate material such as a separator may be used to partition the area where the fuel is burned from the area where the pizza is burned, but the working efficiency and the thermal power are not sufficient.

  In view of the above problems, the present invention is a pizza kiln net-like structure comprising a base and a net-like part extending so as to stand upright from the base and having a self-supporting structure. The net-like part is preferably planar, and may be upright or inclined. The base is preferably a plate, but may be a net.

  It is preferable that the mesh portion is an expanded metal. Expanded metal is a metal plate in a mesh shape in which a metal plate is spread and expanded in a zigzag pattern by an expand manufacturing machine, and the cut is formed into a rhombus or a turtle shell shape. In addition to iron steel plates, non-ferrous metals such as stainless steel plates, aluminum, copper, and titanium, and their alloy plates can also be produced as original plates. There are two types of expanded metal: standard type and grating type. The shape and voids of the mesh can be set as appropriate. Combustion efficiency is better than punching metal.

  The present invention preferably has a basket structure or a box structure. This is to prevent the fuel from spilling out. The basket structure has a bottom plate made of a plate material and a side surface made of a net-like portion. In the box type, the bottom plate is a plate material, and a part of the side surface is a mesh portion.

  It is preferable that the mesh portion of the present invention extends upward so as to be inclined from the end portion of the base portion. Due to such an overhang structure, heat is applied to the pizza diagonally from above, so that the combustion efficiency of the pizza is increased.

  Various dimensions can be set depending on applications such as business use and home use. If an example used for a household stone kiln is given, 20-30 cm in width, 35-50 cm in length, and 10-20 cm in height are preferable.

  According to the present invention, since the heating power can be increased without taking up the place of fuel, the pizza baking time can be shortened. In addition, the operation of moving or cleaning fuel such as firewood or charcoal is simplified, and the work efficiency is improved.

  A network structure 1 for a pizza kiln according to a first embodiment of the present invention will be described with reference to FIG. The network structure 1 for a pizza kiln includes a base 2 and a net-like part 3 extending so as to be erected from the base 2 and is characterized by being capable of self-supporting. Hereinafter, each element will be described in detail.

  The base 2 is an L-shaped plate made of steel. Here, no hole is formed in the base 1, but it may be formed as appropriate. The base 1 is substantially rectangular and the corners are chamfered. The area of the bottom plate is larger than that of the upright plate to ensure self-supporting stability. A net-like part 3 extends in an inclined direction from the upright plate. Due to such an overhang structure, heat is applied to the pizza diagonally from above, so that the combustion efficiency of the pizza is increased. Of course, the net 3 may be upright.

  This net-like part 3 is comprised by the expanded metal manufactured from a steel plate. For example, the mesh size is XP12 × 30.5 in the JIS standard (JISG3351), but is not limited and can be selected from an appropriate range. The mesh portion 3 is planar. The base portion 2 is preferably a plate body, but may be a mesh body made of punched metal. The mesh size of the mesh can be set as appropriate, but if it is too small, the air flow is relatively poor, and if it is too large, the fuel tends to fall relatively easily.

  Here, the network structure 1 for a pizza kiln is for a household pizza kiln. For example, the width 20.5 cm, the length 45 cm, the height 10 to 20 cm, the height of the upright portion of the base 2 is 3 cm, 3 is 12 cm wide and 45 cm long. A large amount (for example, about 3 to 5 kg) of firewood or charcoal can be stacked and burned. Dimensions can be used from home use to specialty stores. If it is smaller than the size of the pizza kiln, the thermal power is small, and if the size is large, it cannot be accommodated in the pizza kiln, or the network structure 1 for the pizza kiln becomes an obstacle, so the size is set appropriately.

  The usage method of the network structure 1 for pizza kilns of this embodiment is demonstrated. The preburned fuel is placed on the pizza baking area on the hearth, and the pizza kiln net-like structure 1 is disposed close to the fuel (see FIG. 6). Hot air flows in the kiln, heating the firing area and raising the temperature. There is an effect that the fuel can directly heat the firing region. Check that the temperature is suitable for firing with a thermometer. Next, the network structure 1 for pizza kiln and the fuel are slid as they are and basically moved to the left or right corner (see FIG. 7). This is so as not to get in the way of pizza from the entrance. When baking is complete, the pizza is removed. Such an operation is repeated. When the work is completed, the pizza kiln network structure 1 and the ash are removed and cleaned.

  As mentioned above, according to the network structure 1 for pizza kilns of 1st Embodiment of this invention, since a fuel is blocked by the mesh part 3 during baking of a pizza, it prevents that a fuel collapses and a lot of fuels at once You can increase the thermal power by increasing the volume of the fuel. Moreover, the flow of air is good due to the mesh portion 3. Therefore, the heating power can be increased without taking the place of fuel, the rise time of the hearth temperature is shortened, the combustion efficiency is increased, and the baking time of the pizza can be shortened. For example, in the case of using charcoal, what took 2 hours or more can reach the baking temperature of pizza in 50 to 60 minutes.

  The sliding of the pizza kiln net-like structure 1 using a tool is also simple, so that the slide moving operation or cleaning operation of fuel such as firewood or charcoal is simplified, and the efficiency of the operation accompanying firing is improved.

  A network structure 201 for a pizza kiln according to a second embodiment of the present invention will be described with reference to FIG. The network structure 201 for pizza kiln is a box-shaped base 202 in which the shape of the base 2 of the pizza kiln network 1 of the first embodiment is changed, and the net 3 is an upright net 203. Is.

  Since the base 201 has a box structure, it is possible to prevent fuel from spilling out. The base 201 is a plate member whose bottom plate is a plate, and the side surface is a substantially arc-shaped portion on the rear side, a pair of linear portions on the side surface, and the upright mesh portion 203 on the front side. The reason why the rear side is substantially arc-shaped is to match the shape of the dome-shaped kiln. Depending on the type of kiln, the side surface may be square.

  The effect of the network structure 201 for the pizza kiln of the second embodiment is basically the same as that of the first embodiment. However, since the box-shaped structure is used, even if it slides on the hearth of the kiln, the fuel together with the fuel Since it can slide so that it does not spill, sliding work is easy and can be done in a short time.

  A network structure 301 for a pizza kiln according to a third embodiment of the present invention will be described with reference to FIGS. This is basically the same as in the second embodiment, but is characterized by a basket structure in which the entire side surface is a mesh portion 303.

  The base portion 302 is L-shaped, and a mesh portion 303 is joined to the outside of the upright portion.

  The front surface portion of the mesh portion 303 is inclined forward (side disposed at the entrance) so that the pizza can be heated from an oblique upper portion. Further, the height is set to be equal between the front surface and the other surfaces. Thereby, a larger amount of fuel can be accommodated.

  As shown in FIG. 3 and FIG. 4, chamfering is performed on the mesh portion 3 on the side surface on the rear side (side to be arranged on the wall side), thereby forming a polygonal shape (here, a pentagon) in plan view. The wall on the back of the round pizza kiln has an arc, so it avoids a shape that fits exactly and makes it easier for air to flow through.

  As shown in FIGS. 3 and 4, a predetermined number, for example, at least a pair of protrusions 304 is provided, and the pizza dough is pushed in with pizza peel when pushed. When pulling out the network structure 301 for the pizza kiln, it will come out if it is hooked on the mesh of the mesh section 303 with a hook. Moreover, as shown in FIG. 3, it can also prevent that the residue of charcoal accumulates by installing the protrusion part 304 at some height intervals from the bottom face. Further, as shown in FIG. 4, the protrusion 304 can be extended from the base 302 to be provided on the bottom surface.

  A network structure for a pizza kiln according to a fourth embodiment of the present invention will be described with reference to FIG. This is basically the same as that of the third embodiment, but is characterized by a basket structure that is shaped like a circular arc with the back side of the side face being an arc.
