Description

This invention relates to a so-called rocket stove.

The structure of a rocket stove consists of a combustion chamber (burn tunnel) where firewood and pellets are put in and burned, followed by a combustion cylinder (heat riser). It is a structure that leads to (heat riser) and causes secondary combustion. Due to the high temperature of the combustion cylinder due to secondary combustion, the air expands, creating a strong ascending current, increasing the exhaust force inside the combustion cylinder, increasing the amount of air taken in from the intake port, and increasing the combustion. done.

The rocket stove with the above-mentioned combustion action has high combustion efficiency and good heating effect, but it is structurally large and inconvenient to transport. Therefore, as shown in Patent Document 1, there is shown an example of making a rocket stove by combining a plurality of blocks made of heat-insulating refractory material so as to form a substantially rectangular parallelepiped.
That is, the burn tunnel block 1, the heat riser block 3, the trivet block 4, etc. are assembled in a corridor style. Then, the firing port block 2 is arranged laterally of the burn tunnel block 1 and assembled.

Patent Document 2 describes a rocket stove that maintains high combustibility and reduces the weight of the stove body. A heat riser is formed in the body of the stove so as to obtain a heat insulating effect by the double cylinder of the stove body.

The object of this invention is to provide a stove that can be easily disassembled and carried, is not bulky, can cook food, and uses fuel pellets or wood.

The stove according to this invention is provided with a box-shaped stove main body that serves as a combustion chamber, and a partition wall is provided in the central part inside this stove main body to divide the combustion chamber into two, a primary combustion chamber and a downstream combustion chamber. forming a secondary combustion chamber,
The primary combustion chamber is provided with a fuel supply rostle and an air intake provided with adjustment means for taking in air into the combustion chamber,
The secondary combustion chamber is provided with a chimney for discharging the flame and unburned gas after the primary combustion. It is characterized by having

As a result, the fuel is burned in the primary combustion chamber, and the combustion flame and unburned gas reach the secondary combustion chamber adjacent to this primary combustion chamber, burning and becoming hot, and the air inside expands and rises strongly. Airflow is generated, and the effect of increasing the amount of air introduced into the combustion chamber is obtained, resulting in high combustion efficiency.
In addition, the cylindrical oven in the secondary combustion chamber can be cooked by opening the lid from the outside and taking in and out food.

The primary combustion chamber and the secondary combustion chamber are arranged in parallel and there is no height difference, so the top plate is flat and does not increase the vertical dimension, and the adjustment tool is placed on the top plate It becomes possible to put it on the table, and it becomes possible to cook outdoors.

The device according to claim 2 has an oven tray that can be pulled out and pulled out to the outside at the lower part of the combustion chamber. Therefore, the radiant heat radiated downward can be effectively used.

In the device according to claim 3, since fire-resistant glass is provided in front of the primary combustion chamber, which is the combustion chamber, to see the internal combustion state, it is possible to visually check the combustion state and see the warmth. is possible.

Since the device according to claim 4 has a charcoal recovery tray and is provided with a set port for charcoal recovery, ash and cinders generated during combustion can be placed on the recovery tray and taken out.

According to a fifth aspect of the invention, the partition wall is erected and fixed to the bottom plate, and the cylindrical oven is provided and fixed along it. For this reason, the tubular oven can be fixed not only to the side wall surface but also to the longitudinal portion of the partition wall, so that a stable mounting state can be maintained.

According to a sixth aspect of the present invention, the adjusting means for introducing air into the primary combustion chamber comprises a desired opening and an air adjusting lid for adjusting the opening area by rotating the opening. Therefore, by rotating the air adjustment cover, the air can be easily adjusted, and the combustion state can be freely adjusted.

The fuel supply glove is a cylindrical pellet glove having a pellet inlet on the top and a glove insertion part that is inserted into the glove insertion opening formed in the stove main body on the bottom of the grate. The insertion part has a pellet reservoir with a large number of holes,
Along one surface of the cylinder, an air introduction path is provided on the outside to suck air from the air suction port and guide the air to the lower side of the rostle insertion part. The air is sucked in through the air introduction passage and guided below the roster insertion part to eliminate the lack of air supply and completely burn the pellets.

The fuel-supplying rostle is a cylinder-shaped rostle having a firewood input port on the upper side and an insertion portion in a rostle insertion port formed in the stove body on the lower side. With the front and bottom parts released,
The reason for this is that the rear plate of the rear part, which allows the flow of air to flow toward the inside of the main body of the stove, is formed in an arc shape. As a result, the flow of the air sucked from the firewood inlet is changed along the arcuate surface of the back plate, and the firewood is burned well.

That is, a partition wall is provided inside the main body of the stove to provide two primary combustion chambers and a secondary combustion chamber. A heat riser could be made downstream in the rectangular box-shaped stove main body, and the structure could be simplified. (Claim 1).

By providing a cylindrical oven in the secondary combustion chamber, radiant heat is applied to the food from the surroundings from the entire solid surface, and stick-shaped sweet potatoes, corn, etc. can be uniformly baked (Claim 1).

It has an oven tray that utilizes radiant heat emitted from the bottom surface of the main body to the outside, and unused heat can be effectively used for cooking food (Claim 2).
In addition, since the front window of the main body is provided with resistant glass, it has the advantage that the combustion state can be checked at all times, and the warmth can be obtained visually (Claim 3).

By using a cylindrical oven with a secondary combustion chamber, long and thin rod-shaped sweet potatoes, corn, etc. can be cooked from the periphery to the entire surface, eliminating unevenly baked portions (claim 5).

In the stove grate of this invention, a large number of holes are formed at the bottom of the grate for pellets, which has a grate insertion part with a pellet storage part at the bottom and a pellet inlet for combustion at the top. Along one surface of the cylindrical body, there is an air introduction path on the outside, through which air is introduced, and the effect is that the supply of air becomes sufficient and the pellets are completely burned (claim 7).

The stove for the stove according to this invention has a firewood inlet at the top and a grate insertion part at the bottom. Since the back plate of the back part that flows in the direction is formed in an arc shape, the air is rectified along the arc surface of the back plate, and the air (wind) is pushed out toward the inside of the stove body to burn firewood well. (Claim 8).
