Description

[Technical field]

[0001] The present invention relates to a pizza oven, and more specifically to a technology for a pizza oven that is equipped with heat sources for both the upper and lower fires, heats the entire oven to a high temperature, enabling full-scale pizza cooking in a short time, and is multifunctional in that it can also create lighting effects using light sources such as combustion flames and lights, and can be folded up into a nested shape for easy transport. [Background technology]

[0002] Pizza (Italian: pizza) (hereafter referred to as pizza) originated in Italy, but is a dish that is widely eaten around the world. In Japan, it has become a popular menu item in the food service industry, from casual family restaurants to authentic Italian restaurants. It has also become so popular as a take-out or delivery product that the term "delivery pizza" has become a common term, and it is popular among a wide range of people, from children to adults. In addition, in outdoor cooking, such as solo camping and backyard cooking, which have become popular due to the influence of the coronavirus infection, people are currently cooking using simple kettles or ovens with electric heaters, even though they cannot prepare a full-scale stone oven.

[0003] To bake delicious pizza, it is best to keep the moisture in the ingredients and bake the pizza so that the surface is crisp and fragrant. The temperature inside the oven is important for this. The "True Neapolitan Pizza Association," which was founded in Naples in 1984 to protect traditional Neapolitan pizza, has detailed regulations on ingredients and baking methods in its regulations, which state that the temperature of the hearth should be about 485 degrees, the temperature of the oven ceiling should be about 430 degrees, and the baking time should be 60 to 90 seconds. The "Japan Neapolitan Pizza Craftsmen Association" also says, "To bake the perfect cornicione or pizza in just over a minute, the temperature inside the oven needs to be 450 degrees and the hearth at least 400 degrees."

[0004] In other words, to bake a full-fledged pizza with a slightly burnt crispy surface and a soft, chewy interior, it is necessary to cook at a high temperature for a short time, and electric heaters have the disadvantage that the cooking time is long because the highest temperature is around 300 degrees. In addition, in conventional pizza ovens where the heat source is only located under the hearth, it takes a long time to start baking because the temperature of the entire oven is raised by convection and heat transfer, and there is a problem that a temperature difference occurs between the ceiling and floor of the oven. In addition, it can be said that an oven that uses a flickering combustion flame is also desirable for creating an atmosphere outdoors.

[0005] Heat sources for kilns that produce flames include gas as well as firewood and charcoal. However, when outdoors, it is preferable to use a heat source such as firewood, which produces a red burning flame, rather than the pale blue flame of gas. While gas can be made smaller by using compact gas cylinders such as those used in portable stoves, most cooking utensils that use firewood or charcoal are large. Therefore, there is a demand for cooking utensils that are small and can be stored compactly, even if they use firewood or charcoal as a heat source.

[0006] In addition, pizza ovens are stored when pizza is not being cooked, but taking them out and putting them back in can be quite a hassle, and it is also desirable to be able to use the oven for other purposes, such as as a lantern or a fire pit, when not cooking pizza.

[0007] In view of this current situation, various technical proposals have been made in the past. The title of the invention is "Assembled Pizza Oven", and the problem to be solved is "to provide a small, lightweight, assembled pizza oven that can be carried anywhere and used, and can be easily brought in and taken out at the storage location or the location of use", and the specific solution is "an assembled pizza oven, in which the top lid is an approximately cylindrical ring-shaped body with a pizza loading / unloading opening on the side and a top surface formed like the bottom of a pot, the inner lid is an approximately cylindrical ring-shaped body with the top surface closed by a pizza baking plate, a circular arc-shaped cut of a predetermined length is made in the peripheral portion of the pizza baking plate at a position opposite the pizza loading / unloading opening, and the pizza baking plate is bent upward along a line connecting the ends of the cut to form a punched upright plate vertically to form a ventilation opening, the bottom oven is formed like the bottom of a pot, a fuel inlet is provided at a predetermined position on the side, and multiple ventilation holes are provided on the side or bottom, the top lid, inner lid and bottom oven are assembled in a stacked structure, and are connected and fixed via a connecting means." However, this technology only has a combustion chamber in the lower part, and utilizes so-called thermal convection, which directs the heat generated in the lower part upward through the ventilation opening. Therefore, the temperature difference between the bottom heat source and the heat source that rises to the top is large, making it difficult to achieve ideal temperature control.

[0008] The name of the invention is "Portable Pizza Oven" and the problem to be solved is "to provide a portable pizza oven capable of high temperatures of 450 to 600 degrees Celsius, comparable to a large stone oven, and capable of baking pizza evenly on both sides in a short time of 90 to 150 seconds." The specific solution is "A metal cylindrical main body 1 requiring a top cover 3 is placed on a base 2. A charcoal grate 4 and a pizza grate 5 are placed inside the main body to form a charcoal combustion chamber A. A dome-shaped heat reflector 6 for baking pizza is placed on top of the pizza grate to form a pizza baking chamber B, and the space between the dome-shaped heat reflector and the top cover is a secondary combustion chamber C." The technology in question is capable of high temperatures of 450 to 600 degrees Celsius, comparable to a stone oven, and capable of baking pizza evenly on both sides in a short time of 90 to 150 seconds, resulting in a texture similar to that of the present invention. However, although it is said that the heat reflected from the heat source by the heat reflector allows the pizza to be cooked evenly and efficiently on both sides, since the material is cast iron, there is a problem that it takes time to preheat it to a high temperature comparable to that of a stone oven.

[0009] The invention is named "Pizza oven", the problem to be solved is "to bake pizza in a short time", and the specific solution is "The pizza oven comprises a casing with a baking chamber inside, a plurality of net-like placement shelves arranged vertically in the baking chamber on which pizzas are placed, an upper heat radiating section and a lower heat radiating section arranged above and below the plurality of placement shelves in the baking chamber for heating the pizza, and a revolution axis extending horizontally between the upper heat radiating section and the lower heat radiating section, and a drive section for revolving the plurality of placement shelves as a unit around the revolution axis between the upper heat radiating section and the lower heat radiating section." This technology comprises an upper heat radiating section and a lower heat radiating section in order to bake pizza in a short time, and the placement shelves are driven vertically to provide heat evenly from above and below, and has a common part with the present invention in that it comprises heat sources above and below. However, this technology uses an electric heater, and since the mounting shelf moves up and down, the baking chamber becomes long in the vertical direction, which has the disadvantage that it cannot be stored compactly. In addition, the structure is complex and expensive. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention is characterized by its feature that it is composed of multiple tubular body parts that can be divided, and that it enables high-temperature cooking by arranging heat sources in two levels, an upper combustion chamber and a lower combustion chamber, and that it can be easily disassembled and assembled and stored in a compact size. The following description will be given based on the drawings. However, the shape and configuration are not limited to those shown in the drawings, and can be modified within the scope of the effect of the invention as a creation of the technical idea.

[0024] 1 is a perspective view illustrating the basic configuration of a knockdown type top and bottom combustion cooking oven 1 according to the present invention. Each component will be described below.

[0025] The assembled top-bottom combustion cooking oven 1 is composed of a plurality of tubular body sections 10, each of which has an upper combustion chamber 30, a middle cooking section 40, and a lower combustion chamber 50. The upper combustion chamber 30 has an upper-stage upper opening 31 that opens upward and an upper-stage side wall 32 that has an upper-stage air intake 33. The middle cooking section 40 has a middle-stage upper opening 41 that opens upward, a middle-stage bottom surface 42, and a cooking plate insertion port 45 that allows a cooking plate 44 to be inserted into the middle-stage side wall 43. The middle-stage bottom surface 42 has a lower portion 50 that is lower than the lower portion 50. and the lower upper surface 54 are separated by a partition material 46 which is a common member, and the lower combustion chamber 50 has a lower side wall 51 which has the partition material 46 at the top, a lower air intake 52 and a combustion material insertion port 56, and a bottom plate 53 which is closed at the lower end of the lower stage, and the upper area portion 34 which constitutes the upper combustion chamber 30, the middle area portion 47 which constitutes the middle cooking section 40, and the lower area portion 54 which constitutes the lower combustion chamber 50 are structured so that they can be disassembled and stored in a nested shape 70.

[0026] Combustibles N are raw materials for combustion, specifically, combustible materials such as firewood and charcoal. Firewood is made by cutting trees and is mainly used for bonfires, while charcoal is made by steaming and carbonizing wood and is mainly used for cooking.

[0027] Coniferous trees are characterized by low density and high oil content, making them easy to burn. Therefore, it is efficient to use them as kindling when starting a bonfire. Examples of tree species include cypress, pine, and cedar. Hardwood firewood is characterized by high density and low oil content, making it difficult to burn. Therefore, it is useful when you want to keep the fire going for a long time. Examples of tree species include oak, sawtooth oak, and Japanese oak.

[0028] The most common types of charcoal (wood charcoal) used for cooking, such as barbecues, are black charcoal, white charcoal, and sawdust charcoal, and black charcoal is easy to use even for beginners. Black charcoal, which has a soft charcoal quality, is available in domestically produced charcoal made from oak and sawtooth oak wood, and in foreign charcoal made from mangroves. Domestically produced black charcoal is easy to light and produces little smoke, making it suitable for cooking, while foreign charcoal has a short burning time and produces a lot of smoke, but is easy to use even for beginners and can be easily purchased at hardware stores.

[0029] White charcoal is hard and difficult to ignite, but once lit, it provides a consistent, stable heat for a long time. It is called white charcoal because it has ash on the surface and is whitish in appearance. A typical example is "Binchotan," which is used in high-end Japanese restaurants. "Binchotan" can take a little more effort to ignite than black charcoal, so it is said to be suitable for people who are accustomed to handling charcoal.

[0030] Sawdust charcoal is made by grinding sawdust into charcoal, then crushing and solidifying it, and is said to have properties similar to binchotan charcoal. It is mostly square or hexagonal in shape, with a hole in the center like a chikuwa fishcake. It is a little difficult to ignite, but the fire lasts a long time, and it does not require frequent replenishment of charcoal. It has properties similar to binchotan charcoal, but is relatively affordable, and is used in restaurants for yakiniku, yakitori, and eel kabayaki. In the drawing, firewood is shown as an example of the combustible material N, but it can also be solid methanol fuel, or liquid fuel such as white gasoline, alcohol, or kerosene, in addition to the above charcoal.

[0031] The main body 10 is the main body that constitutes the cylindrical body. Three layers are formed: an upper combustion chamber 30 at the top, a lower combustion chamber 50 at the bottom, and a middle cooking section 40 between them, which form the side walls of each. Figures 1 and 2 show a cylindrical shape with one upper end open and the opposite lower end closed in the assembled and used state, but the shape is not limited to this, and a square or polygonal cylindrical shape is also possible.

[0032] The legs 20 are provided to prevent the heat from combustion from being transferred to the ground, floor, etc. For campfire pits, local governments and campsites may specify the distance from the bottom to the ground, so it is desirable to provide a space area at least 15 cm high.

[0033] When cooking pizza or bread, the upper combustion chamber 30 can be used to burn the fuel N simultaneously with the lower combustion chamber 50, with heat sources arranged in two tiers, one above the other, or the upper combustion chamber 30 can be used as a campfire by burning the fuel N only in the upper combustion chamber 30, or the upper cooking utensils 35 can be placed in the opening to enjoy a barbecue, etc.

[0034] The upper opening 31 is an opening at the top of the upper combustion chamber 30, and allows for the placement of upper cooking utensils 35 such as a grill during barbecue. When using it as a bonfire, the upper opening 31 is used to remove the upper cooking utensils 35 and insert firewood or other combustion materials N.

[0053] The lower combustion material support member 55 is a member that holds and supports the combustion material N that does not fit inside the lower combustion chamber 50 and protrudes to the outside. It also plays a role in facilitating the discharge of ash after use.

[0054] The combustion material insertion port 56 is an opening hole for introducing combustion material N into the lower combustion chamber 50, and is an opening that allows the combustion material N to protrude outside the side wall 51 of the lower combustion chamber 50 when long firewood is introduced.

[0055] The lower region 57 is a spatial region formed by the lower combustion chamber 50, and is formed integrally with the middle region 47 as a member.

[0056] The foldable type 60 is a mechanism for folding the legs to enable compact storage when a configuration is adopted in which legs are provided on the bottom side of the main body bottom surface 53 of the main body portion 10.

[0057] The leg attachment plate 61 is disposed so as to overlap the outer portion of the bottom plate 53, and the legs 20 are provided on the leg attachment plate 61.
