Description

  The present invention relates to improvement of a stove that uses liquid alcohol as fuel, and in particular, increases the vaporization efficiency of fuel alcohol to achieve high thermal power and stable combustion.

From 1965 to around 1960, when alcohol stoves were frequently used for outdoor cooking and emergency stoves, for example, Japanese Patent Laid-Open Nos. 49-3227, 51-74077, 52-83872, and 52 Many ideas and inventions such as -12605 are found in the literature. However, recently, portable gas stoves that use liquefied butane gas as a fuel have come to be widely used.
Under such circumstances, there have been many people who enjoy climbing and hiking individually, and the stove that uses liquid alcohol, which is small, inexpensive, safe and easy to use, is being recognized again. .

The image that comes from the alcohol stove was that the firepower was weak, and it took too much time to boil and boil the water. It is said to be one.
However, recently, not only has there been an increasing number of individuals who enjoy climbing and hiking individually, but in particular, there have been an increase in the number of middle-aged and elderly people who enjoy these activities, making operation easy, safe and lightweight. There is a growing demand for improvements in small alcohol stoves.

  Therefore, in the present invention, high thermal power and stable combustion are achieved, and the past image that “thermal power is weak and it takes too much time to boil and boil hot water” is wiped out and the operation is easy and safe. It is intended to provide a small and lightweight alcohol stove.

In order to achieve the above object, the alcohol stove of the present invention is a means for solving the problems by the following means. That is, a container (A) in which a stepped portion into which the lower end periphery of the skirt portion of the combustion portion is fitted is formed at the upper end portion of the container body in which the bottom surface in contact with the floor surface is formed flat.
A cylindrical tube (b) having a plurality of cutouts at the lower end edge accommodated in the container,
A flame retardant absorbent material (c) wound around the outer periphery of the cylindrical body;
A stove using alcohol as a fuel composed of a combustion part (d) placed in a form covering the upper end of the cylindrical body,
This combustion part (d) has a skirt part fitted to the step part of the container at the lower end periphery, a lower combustion zone having a plurality of combustion holes above the skirt part, and an entire peripheral wall above the combustion zone And an upper combustion zone in which a plurality of combustion holes are provided toward the upper edge of the container, and the container body 1 and the cylindrical body (b) and the combustion are included among the constituent members. The part (d) is made of titanium and is also lighter.

Since the alcohol stove according to the present invention has the above-described configuration, the following effects can be obtained.
It consists of four parts: a container, a cylinder, a flame retardant absorbent material, and a combustion part. The container has a flat bottom that comes into contact with the floor, and the upper end of the skirt is fitted around the bottom edge of the skirt of the combustion part. The step part to insert is provided in the perimeter. Therefore, there is no worry about the stability when placed on the floor surface, and the container and the combustor are well accommodated, which ensures stable combustion.

  The cylindrical tube housed in the container body has a plurality of cutouts at the lower edge, and the injected fuel flows out of the cutouts toward the container and is filled into the container. It penetrates into the flame retardant absorbent material wound in close contact with the outer periphery of the cylinder to promote combustion. That is, the cylindrical body plays the role of installing the flame retardant absorbent material in a certain shape, and also has the effect of making the amount of fuel outflow toward the container by the notch portion at the lower end edge.

The combustion part placed on the upper end of the cylindrical body is the most important member in the present invention, and the skirt part is fitted into the stepped part of the container as described above to integrate the container and the combustion part. This ensures a stable combustion.
The effect of the present invention that should be noted here is the existence of a lower combustion zone in which a plurality of combustion holes are provided, and a vertical wall that is formed all around the upper combustion zone. In other words, when the flame from the combustion hole in the lower combustion zone rises upward, the whole vertical wall is heated by rising along the vertical wall, which increases the efficiency of fuel alcohol vaporization and stabilizes it. It plays an important role in the effect of combustion.

  It is said that the combustion part has a high heating power by providing combustion parts at the lower part and the upper part through a hanging wall between the lower combustion zone and the upper combustion zone, and “it takes time to cook”. You can wipe out the image of the past alcohol stove.

  Among the structural members, the other members except for the flame retardant absorbent material are made of titanium and are lightweight, making them ideal for middle-aged mountain climbers.

The alcohol stove of the present invention is composed of four members,
The first member is a container (a) having a substantially bowl-like shape whose bottom surface in contact with the floor surface is formed in a flat shape and having a capacity of about 80 to 130 ml. The container is a main body 1 serving as a fuel container and a combustion section described later. The upper end portion is formed with a step portion 2 into which the lower edge of the skirt portion is fitted.

  The second member is a cylindrical body (b) having a height (length) of about 40 to 50 mm, which is housed in the central part of the container (a), and a plurality of notches are formed on the lower edge of the cylindrical body. A portion 12 is provided, and the cut-out portion is for the injected fuel to flow out into the container and is preferably provided at four locations with a size of about 10 mm for the frontage and about 3 mm for the maximum height.

  The third member is a flame retardant absorbent material (c) wound in close contact with the outer periphery of the cylindrical body, which penetrates the absorbent material and promotes combustion, and is made of glass fiber or the like. In addition to the flame retardant absorbent material, it may be expressed as a non-flammable absorbent material.

The fourth member is a combustion part (d), and the lower peripheral edge is a skirt part fitted into the step part of the container (b). The upper part of the skirt part is substantially flat and has a plurality of combustion holes all around it. A lower combustion zone is formed, and a vertical wall is formed on the entire circumference with a height of about 10 mm upward from here, and the upper end edge of the vertical wall is narrowed by about 15 mm in diameter. Thus, an upper combustion zone having a small diameter and a warm inclination and having a plurality of combustion holes is formed.
Of these four members constituting the present invention, the other members are made of titanium except for the flame retardant absorbent material of the third member.

  The alcohol stove A according to the present invention will be described based on the embodiment shown in the drawings. ), And the first member container (a) has a flat bottom surface in contact with the floor surface and a substantially bowl-shaped capacity of about 80 to 130 ml. The container is a fuel container. The upper end portion is formed with a step portion 2 into which the lower end periphery of the skirt portion 31 of the main body 1 and the later-described combustion portion (d) is fitted.

The cylinder (b) shown in FIG. 1 is housed in the center of the container (b), and a notch 12 is provided at the lower end of the cylinder body 11.
In the flame retardant absorbent material indicated by reference numeral (c) in the figure, the entire surface of the main body 21 is formed of a flame retardant or non-flammable absorbent material, and is wound around the entire outer periphery of the tube main body 11.

  In FIG. 1, the reference numeral (d) indicates a combustion part, and a lower peripheral edge thereof has a skirt part 31 fitted into the step part 2 of the container (b), and the skirt part 31 has a plurality of combustion holes. A flat lower combustion zone 32 has a vertical wall 33 extending upward from the zone 32, and a plurality of combustion holes having a small diameter and a warm inclination are formed toward the upper end edge. The upper combustion zone 34 provided is formed.

  FIG. 2 shows the alcohol stove of the present invention that has been assembled by each member described with reference to FIG. 1, and a cylindrical body (b) around which a flame retardant absorbent material (c) is wound around a container ( The combustion part is placed so as to cover the upper part of the cylindrical body (b), the skirt part of the combustion part is fitted into the step part of the container (a), and the upper edge of the step part is placed on the skirt part. It presses against the upper part to prevent fuel leakage from here.

The alcohol stove according to the present invention includes a container having a stepped portion at the upper end portion into which the lower end periphery of the combustion portion is fitted, a cylindrical tube having a notch at the lower end edge accommodated in the vessel, and an outer periphery of the tube A flame retardant absorbent material wound around a cylinder and a combustion part placed in a form that covers the upper end of the cylindrical body, and the combustion part has a skirt part fitted at the stepped part of the container at the lower edge. Above the skirt is a planar lower combustion zone having combustion holes. Above the skirt is an upper combustion zone that forms a whole wall and a combustion hole toward the upper edge. It is also characterized by the fact that other components are made of titanium except for the flame retardant absorbent, and it is lightweight and highly safe, and fuel alcohol is vaporized It is intended to increase efficiency and achieve high thermal power and stable combustion.
