Description

The present invention relates to a heating device for cooking which uses a flame generated by burning fuel pellets such as wood pellets as a heat source for cooking.

Traditionally, cooking such as camping and barbecues is generally done in large outdoor areas, but due to the spread and diversification of leisure, the rooftops of buildings and gardens of ordinary houses are popular. It has also come to be performed in relatively narrow places such as. Along with this, black smoke generated due to incomplete combustion of fuel during cooking has become a problem, and there is an increasing demand for cooking heating appliances that do not generate black smoke.

On the other hand, wood pellets are carbon neutral, do not increase carbon dioxide in the atmosphere like fossil fuels, and are clean and environmentally friendly energy sources. In addition, wood pellets are attracting attention because they are cheaper than fossil fuels, easier to transport and store than firewood and charcoal, and less likely to generate black smoke.

Examples of the heating device for cooking using such wood pellets include, for example, a solid fuel storage body that stores the wood pellets and has an air permeable fuel holding member at the lower end, and a combustion unit provided below the solid fuel storage body. A heating appliance for cooking has been proposed, which has a chamber and an exhaust device in communication with the combustion chamber, and has a solid fuel container provided with an outside air suction port (see Patent Document 1).

JP, 2009-19846, A

In the heating device for cooking of the above-mentioned patent document 1, since the amount of air contacting the wood pellets is not sufficient, complete combustion cannot be achieved, and it is not always possible to sufficiently suppress the generation of black smoke. In addition, since the amount of air that comes into contact with the wood pellets is small, it cannot be said that the combustion efficiency of the wood pellets is sufficiently high, and it is difficult to raise the temperature of the cooking section, and to make it a sufficient heat source for cooking. There was a problem that a large amount of wood pellets was needed.

Furthermore, in the conventional cooking appliance including the cooking appliance of Patent Document 1, since the flame generated by the burning of the wood pellets is guided in the cooking section in the horizontal direction (lateral direction), the temperature of the cooking section is intended. There are also problems that it is difficult to raise the temperature, and that the flow of flames and smoke is so bad that it is necessary to burn the wood pellets directly under the chimney in order to promote the chimney effect.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cooking appliance with high combustion efficiency that emits little black smoke and can perform sufficient heating with a small amount of fuel pellets. To do.

A cooking device having a cooking section and a chimney which is erected in communication with the cooking section and which discharges smoke to the outside. The combustion chamber, the flame guiding section, the cooking section and the chimney communicate with each other in the internal space. .. Then, the combustion chamber includes a combustion unit and a pellet storage unit that is provided upright above the combustion unit, and the combustion unit burns the fuel pellets dropped from the pellet storage unit, and a combustion main unit. A pellet having a first air supply portion provided below and supplying air to the combustion main body from below, and a pellet containing portion having a pellet dropping opening through which a predetermined fuel pellet can be dropped at a lower portion thereof. It is characterized in that it comprises an accommodating main body part and a second air supply part provided in parallel with the pellet accommodating main part and supplying air to the combustion main part from above.

In the heating device for cooking of the present invention, the fuel pellets can be burned in the presence of sufficient air, and a sufficient stack effect can be obtained, so that the generation of black smoke can be suppressed. Further, the cooking section can be efficiently heated, and the temperature can be made higher than that of the conventional one.
In addition, the heating device for cooking of the present invention can be used not only for cooking but also for heating.

Since the heating appliance for cooking of the present invention is one in which a flame passes through the internal space, it is preferably made of a material having fire resistance, and examples of the material include iron, stainless steel and the like. it can.

Various fuel pellets may be used as the fuel pellets used in the cooking apparatus of the present invention, but wood pellets are preferable from the viewpoint of environmental protection. As the wood pellets, commercially available wood pellets such as wood pellets, whole wood pellets and bark pellets can be used. The wood pellet is usually a solid fuel obtained by drying wood, pulverizing it, and compressing it under pressure, and generally has a cylindrical shape with a diameter of about 5 to 10 mm and a length of about 5 to 40 mm.

First, the combustion chamber in the heating device for cooking of the present invention will be described.
As described above, the combustion chamber includes the combustion section and the pellet storage section that is provided upright above the combustion section, and is a place where the fuel pellets are burned. The flame generated here is sent to the flame guiding part, reaches the cooking part, and heats the cooking part.

The combustion unit is not particularly limited as long as it is a structure capable of burning the fuel pellets, and examples thereof include a structure in which a cylindrical member having a combustion space inside is provided laterally such as a cylindrical shape or a rectangular tube shape. be able to.

The combustion section is provided below the combustion main body, and a combustion main body that combusts fuel pellets injected from a pellet storage located above, and a first air supply section that supplies air to the combustion main body from below. It is equipped with. For example, a partition plate having a large number of openings is installed in the lower portion of a horizontally-arranged tubular member as a combustion unit, so that the combustion main body unit and the first air supply unit are formed separately.

It is preferable that the combustion main body portion of the combustion portion is provided with a flame introduction port for introducing a flame that ignites the fuel pellets. Further, it is preferable to provide an air adjusting port for adjusting the amount of air at the time of combustion. As a configuration provided with such a fire type introduction port and an air adjustment port, for example, a door (fire type introduction port) is provided in the combustion main body portion of the one-side open portion of the horizontally arranged tubular member as the combustion unit, A configuration in which such a door is provided with a window (air adjustment port) that can be opened and closed can be given.

Further, the first air supply unit is not particularly limited as long as it is provided below the combustion main body and can supply air to the combustion main body from below. An example is a configuration in which a door is not provided at an opening portion on one side of the first air supply portion (lower portion) of the provided tubular member and the door is opened. As a result, the air from the outside is introduced into the first air supply section, and as described above, the combustion main body section and the first air supply section are separated from each other by the partition plate having a large number of openings. Air will flow into the main body evenly from below. Therefore, in the combustion main body, the fuel pellets are burned in an environment where there is sufficient air. The first air supply unit also serves as an ash storage unit that stores the ash of the fuel pellets burned in the combustion main body.

The pellet accommodating portion erected above the combustion portion is not particularly limited as long as it has a structure capable of accommodating fuel pellets, and is, for example, a cylindrical member having an accommodating space such as a cylindrical shape or a rectangular tube shape. There can be mentioned a structure in which The pellet accommodating portion includes a pellet accommodating main body portion and a second air supply portion provided in parallel with the pellet accommodating main body portion, and the pellet accommodating portion may be installed upright with the second air supply portion facing upward. preferable. The inclination angle is preferably about 5 to 30°, more preferably about 15 to 25°. By being installed upright, it is possible to easily guide the smoke generated in the pellet accommodating main body to the second air supply unit, and more reliably prevent the backfire in which the flame goes in the opposite direction to the cooking unit side. can do.

It is preferable that the pellet accommodating main body portion has a pellet filling port into which a fuel pellet can be introduced, on the upper side thereof.
Further, the pellet accommodating main body portion has a pellet dropping opening capable of dropping a predetermined fuel pellet in a lower portion thereof. As the pellet dropping opening, an automatic or manual opening/closing door may be provided to intermittently drop the pellet, but it is possible to drop a partially burned fuel pellet to the combustion main body. It is preferably a drop control opening. That is, in the cooking appliance of the present invention, the tip of the flame generated by the combustion of the fuel pellets of the combustion main body burns the fuel pellets of the lower portion of the pellet housing main body, and the fuel pellets are small accordingly. Therefore, it is preferable that the pellet dropping opening is a drop control opening adjusted to have a size and a shape in which the fuel pellets, which have become small due to a part of the combustion, gradually drop. Specifically, examples of the drop control opening include an opening formed by a lattice or a fence.

Since the amount of fuel pellets falling from the fall control opening is adjusted to an appropriate amount, the amount of fuel pellets to be burned is also adjusted to an appropriate amount, and proper combustion in the combustion main body is continuously performed. And a stable flame is generated. Therefore, the cooking section is stably heated by this flame.

The pellet accommodating main body preferably includes a pellet case in which pellets are filled. As a result, pellets can be filled and the pellet case can be washed while the device is removed from the instrument body. Further, it is preferable that the pellet accommodating main body has a lid. This makes it possible to easily guide the smoke generated in the pellet housing main body to the second air supply unit.

The second air supply unit arranged in parallel with the pellet storage main body allows air introduced from the outside to flow into the combustion main body from above, and for example, the second air supply unit can store the pellets in a tubular member that is erected as the pellet storage unit. It can be formed by providing a partition plate which is separated from the main body. The second air supply unit has, for example, an air port through which air flows from the outside on its upper surface (opening portion on the upper side of the tubular member), and its lower surface (opening portion on the lower side of the tubular member), It has an air port that communicates with the combustion body.

The pellet accommodating main body portion and the second air supply portion may be completely partitioned by a partition plate, but it is preferable that the pellet accommodating main body portion and the second air supply portion have a ventilation opening that communicates with each other. As a result, as the combustion progresses, the smoke generated in the pellet containing main body moves to the second air supply section and is carried to the combustion main body by the flow of air from the outside generated in the second air supply section. become. Therefore, the gas and smoke generated by the incomplete combustion of the fuel pellets are completely combusted. As described above, since the pellet storage main body is provided with the lid and the pellet storage is inclined, the guide to the second air supply unit becomes easier.

The ventilation opening is not particularly limited as long as it can communicate the pellet storage portion and the second air supply portion and can ventilate each other. For example, one or more slits having a predetermined width, or a grid is used. The opening formed and the slit formed by the fence can be mentioned. Specifically, when the pellet accommodation section and the second air supply section are arranged in parallel with a common partition plate (side wall) interposed therebetween, the pellet accommodation main section is an opening that penetrates the partition plate. In the case where the pellet case is provided, the opening is formed in the pellet case (when there is no partition plate), or the opening formed in the pellet case and the opening penetrating the partition plate. The openings formed in the pellet case and the openings penetrating the partition plate may all correspond (communicate) or may partially correspond.

Next, the flame guide part of the present invention will be described.
The flame guide part is a part that communicates with the combustion chamber and guides the generated flame to the cooking part. The shape of the flame guide portion is not particularly limited as long as it is a shape that guides the flame from the combustion chamber to the cooking portion, and examples thereof include a cylindrical shape and a rectangular tube shape.

It is preferable that the flame guiding portion extends upward from the upper surface of the combustion portion. That is, it is preferable that the cooking section is provided at a position higher than the combustion main body section of the combustion chamber. As a result, the flame generated in the combustion section moves along with the rising air current, and it is possible to guide the flame to the cooking section while suppressing the decrease in the amount of heat, so that the flame directly contacts the upper surface of the cooking section. Therefore, the upper surface (heating surface) of the cooking section can be effectively heated.
In the conventional cooking heater of the type in which the flame advances in the lateral direction similar to the cooking heater of the present invention, the flame does not directly contact with (the back side of) the upper plate of the cooking section, and the temperature is unlikely to rise. Therefore, the temperature usually rises only up to about 400°C, and it was difficult to raise the temperature up to 500°C even if a large amount of pellets were burned. On the other hand, the heating cooker actually manufactured by the present inventors achieved 650° C. or higher.

Next, the cooking section will be described.
The cooking section is a section that communicates with the flame induction section, has its surface heated by the induced flame, and can be cooked on the heated surface. The shape of the cooking section is not particularly limited as long as it has an internal space for allowing the flame to pass through, but from the viewpoint of easy cooking, a tubular member having a flat plate-shaped upper surface serving as a cooking surface is preferable. Further, it is preferable that the tubular member has a shape elongated in the axial direction. The size of the cooking section can be appropriately set depending on the application, and for example, it is preferably about 300 to 1000 mm horizontally (axial direction) and about 200 to 600 mm vertically.

Further, it is preferable that a cooking heating shelf is provided below the cooking section. Thus, the cooking can be performed at a position slightly apart from the bottom surface of the cooking unit and at a temperature lower than that of the top surface (heating cooking surface) of the cooking unit. Specifically, for example, the cooking heating shelf can be used as an oven for cooking pizza and the like.

Finally, the chimney section will be described.
The chimney section is erected in communication with the cooking section and discharges smoke to the outside. The chimney part may be provided at any position of the cooking part, but is preferably provided on the side opposite to the side communicating with the flame guiding part. That is, it is preferably provided on the side portion far from the combustion chamber. Thereby, the surface of the cooking section between the flame guiding section and the chimney section can be used as the cooking surface to the maximum extent.

Further, the size of the chimney portion can be appropriately set depending on the application, and can be, for example, a diameter of about 50 to 150 mm and a length of about 600 to 1500 mm. The chimney portion preferably has a tapered shape in order to increase the chimney effect. Further, it is preferable that the chimney part is an assembling type that is detachable from the cooking part. This allows it to be compact when not in use, making it easy to carry and store.
The smoke exhausted from the chimney portion of the heating appliance for cooking actually manufactured by the present inventors is not black smoke except black smoke that is discharged in a small amount immediately after the start of combustion (about 1 minute). It is white smoke or colorless and transparent smoke.
