Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the configuration of a stove that uses solid fuel contained in a can as a heat source.

[Conventional example]

Stoves that are commonly used these days include electric,
Most of them use gas or oil as their heat source.

[Problem that the invention attempts to solve]

In the conventional stoves mentioned above, both electric stoves and gas stoves require a connection part with the fuel source, that is, an electric cord or gas piping, which limits the places where they can be used. It is inconvenient to use outdoors, and kerosene stoves are similarly inconvenient to use portable, and they have a particularly precise and complicated structure to increase combustion efficiency and prevent harmful gases from being produced. It was not something that could be used very easily.

The present invention utilizes solid fuel, which has relatively low thermal power, as a fuel source and functions as an effective stove, thereby creating a portable stove that is especially convenient for outdoor use. The purpose is to provide.

[Means for solving problems]

In order to achieve the above object, the present invention employs the following configuration as a solid fuel stove.

That is, a solid fuel can containing solid fuel and having a can opening on the upper surface, an upper opening and a lower opening disposed directly above the can opening, and a solid fuel can having an upper opening and a lower opening disposed directly above the can opening, and a solid fuel can that is arranged on the entire circumferential wall on average. It is characterized by a structure consisting of a cylindrical part having a large number of through holes.

[Effect]

The flame exposed from the mouth of the solid fuel can reaches into the lower mouth of the cylindrical part and heats the surrounding air, creating an upward airflow within the cylindrical part, but at this time, the atmospheric pressure in the heated part increases. A difference is generated, and outside air is allowed to flow in as needed from a large number of through holes located near the edge of the lower mouth of the cylindrical portion. The appropriate amount of oxygen contained in this incoming air facilitates the combustion of the solid fuel and produces the necessary amount of heat for the stove. The upper opening on the cylindrical portion also provides a passage for the upward air flow to exit.
In addition, when a heat dissipation plate or the like is placed on the edge of the upper opening, the large number of through holes present on the edge of the upper opening function as exhaust ports according to the pressure of the rising air, and the heated air is discharged. It leaks outside.

〔Example〕

Next, embodiments of the present invention will be described.

A solid fuel stove 1 according to a first embodiment is shown in a perspective view in FIG. This solid fuel stove 1 includes a cylindrical part 2 formed of a mesh material into a cylindrical shape having an upper mouth part 3 and a lower mouth part 4, and this cylindrical part 2 has an edge of the lower mouth part 4. Half can container solid fuel can 5
It is arranged on the solid fuel can 5 so as to be located directly above the opened can mouth 6 in contact with the upper surface 5a of the solid fuel can.

As shown in FIG. 2, in the solid fuel stove 1, the flame 8 of the solid fuel 7 combusting in the solid fuel can 5 is exposed from the can mouth 6, and the cylindrical part The air present near the lower mouth part 4 of the lower part of 2 is heated. This heated air generates an ascending hot air flow B, but at this time, a pressure difference occurs in the area near the lower part 4, resulting in a reduced pressure state. In response to this reduced pressure state, a large number of mesh holes 2 are located near the lower opening 4.
An inflow airflow A is obtained from the outside via a.

The amount of this incoming airflow A... can be obtained as needed in response to the pressure difference at any point in time. Therefore, the combustion of the solid fuel 7 is made stable and its combustion efficiency is increased.

In addition, in this first embodiment, the hot air flow B acts as an internal pressure in areas other than the mesh holes 2a associated with the inflow air flows A on the cylindrical portion 2.
For this reason, there is little airflow in and out of these parts, and they function as a wind tunnel. In addition, the hot air flow B
The upper opening 3 functions as an exhaust port.

Next, FIG. 3 shows a cylindrical portion 2' to be applied to a solid fuel stove in a second embodiment.

The inflow air flow A that appropriately flows in from the mesh holes 2a near the lower mouth portion 4'' generates a hot air flow B that rises within the cylindrical portion 2''. This hot air flow B collides with the surface of the heat sink 12 that closes the upper opening 3'' through a portion functioning as a wind tunnel in the cylindrical portion 2'' and is reflected, and is mainly affected by the air flow pressure at the upper opening 3''. An outflow airflow A' is generated that flows out from the mesh holes 2a on the `` side.This outflow airflow A' is similar to the rising hot airflow B.
It functions to flow out from appropriate mesh holes 2a depending on the pressure.

In this way, the solid fuel stove according to the present invention does not require a device configuration for adjusting the amounts of the inflow airflow A and the outflow airflow A', and the above-mentioned airflow rates are adjusted as necessary in the natural state. The combustion efficiency of the solid fuel 7 is good and its combustion is stable.

Further, in the third embodiment, the amount of heat is efficiently transferred to the heat sink 12 according to the air flow pressure caused by the hot air flow B.
