Description

[Detailed description of the invention] This invention relates to an improved structure of a household stove that uses solid fuel such as firewood, wood chips, garbage, coal, etc., and includes a slag processing structure and a combustion structure. This is a new version with new improvements.

Household stoves that use solid fuel have been in practical use for a very long time and were widely used in households.
Overwhelmed by kerosene stoves, gas stoves, etc., these stoves are now used only in small numbers of households in rural areas and at workplaces.

The main reason for this situation is not only the inconvenience of handling solid fuel, but also the complicated problem of disposing of slag after use, which is not the case with stoves that use other fuels. This is because it is largely derived from.

On the other hand, maintenance costs for kerosene stoves, gas stoves, etc., which are the mainstays for home use, are gradually rising due to the depletion of oil resources, and each household has no choice but to limit their usage time as a self-defense measure. As a result, they are forced to live an unpleasant home life by restricting their consumption and reducing their combustion rate.

Therefore, in order to deal with these current situations and ensure a rich life in the future, this idea has been developed to improve the very traditional household stove that uses solid fuel so that it is fully compatible with the lifestyles of modern people. Through further development, we have succeeded in commercializing a household stove with an improved structure as detailed below.

As can be understood from the representative embodiment shown in the drawings, the household stove of this invention basically consists of a stove body 1
and a vertical main combustion chamber 2 combined with the stove body 1.

The stove body 1 includes a bottom plate 11, an outer plate 12, a top plate 13,
A rectangular ash removal opening 15 is formed in the bottom plate 11 from the legs or a skirt portion 14 that also serves as the legs, and a rectangular ash removal opening 15 extending from approximately the center to the outer side is combined with a pull-out ash removal box 3 at the bottom of the bottom plate 11. It will be done.

The top plate 13 has a circular fitting hole 16 formed in its center, and a chimney connection port 17 formed on the outside thereof.

The position of the chimney connection port 17 is shifted to either the left or right side from the ash removal box 3 (that is, the position of the ash removal port 15) assembled at the bottom of the bottom plate 11 due to the planar arrangement, and overlaps vertically. (In the embodiment, it is shifted to the left side of the ash collecting box 3 on the plane, but it may naturally be on the right side), and the partition plate 18 is formed within this shifted range. However, this partition plate 18 is
In terms of planar arrangement, it is further restricted so that it does not protrude into the circular fitting hole 16 of the top plate 13, and is planned to partition the inside of the stove body 1 that is outside the circular fitting hole 16.

In addition, in the figure, D is a damper provided at the chimney connection port 17,
R indicates a rostrum, and W indicates a small transparent window that may be provided on the outer panel 12 as necessary.

On the other hand, the vertical main combustion chamber 2 is a cylindrical body with a circular cross section that matches the fitting hole 16 of the stove body 1.
It is formed so that it can be rotated horizontally while being fitted into the
At the bottom, there is a ash scraping plate 21 that rotates as if it were licking the top of the bottom plate 11 when the vertical main combustion chamber 2 is horizontally rotated.
is formed.

By rotating the ash scraper plate 21, all the ash and other cinders remaining on the stove body bottom plate 11 are scraped up and dropped into the ash removal box 3 from the bottom plate ash removal port 15. The ash scraper plate 21 faces from the inside of the stove body outer plate 12 toward the approximate center of the bottom plate 11, and is set at an appropriate height with a length that covers the ash outlet 15.
(sufficiently) with a height of the order of 1 to 1).

The installation position is on the side of the chimney connection port 17 of the stove body partition plate 18, with the flue port 22 provided on the outside of the lower part of the vertical main combustion chamber 2 facing toward the direction in which the ash removal box 3 is pulled out. It must be regulated and formed so that it is located at

In the illustrated embodiment, the vertical main combustion chamber 2 is divided into two parts, and the upper part can be inserted into the lower part at an appropriate depth, and the length of the solid fuel, such as firewood or pieces of wood, can be inserted into the lower part. A fuel injection lid 23 whose total height can be freely adjusted according to the
However, it is not necessarily necessary to form this fuel injection lid 23, and it is also possible to simply form a fuel injection lid in which only the upper plate of the vertical main combustion chamber 2 is removable.

In the figure, 19 is a slide support frame for storing the ash collecting box 3;
24 is a fitting piece that fits into the rising piece of the stove body fitting hole 16; 25 is a throttle for controlling combustion; 26 is a fitting piece that fits into the rising piece of the stove body fitting hole 16;
27 is a handle for rotating the main combustion chamber 2; 28 is a combustion confirmation window; 31 is an air volume adjustment port provided on the front of the ash collecting box 3; 32 is a handle for the fuel input lid 23; Each grip handle is shown.

In the household stove of this invention formed as described above, firstly, the vertical main combustion chamber 2 is placed in the stove body 1 so that the ash scraping plate 21 properly contacts the chimney connection port 17 side of the partition plate 18. After fitting and rotating so that they touch each other, remove the fuel injection lid 23, pour solid fuel into the vertical main combustion chamber 2, and ignite it.
The flame and smoke in the main combustion chamber 2 are guided to the outside of the stove body 1 from the flue opening 22, and are passed through the chimney via the flue S formed by the outer periphery of the main combustion chamber 2 and the inner wall of the stove body 1. The smoke reaches the connection port 17 and is discharged from the chimney as smoke.

Therefore, in this combustion process, the fuel simply flows into the main combustion chamber.
The flame and smoke not only burn within the stove but also circulate within the flue S of the stove body 1 from the flue port 22 to the chimney connection port 17, resulting in a stove with extremely high combustion efficiency.

Ash and other cinders generated during combustion, except for those that fall directly into the ash removal box 3 through the Rosdol R, are deposited on the bottom plate 11 of the vertical main combustion chamber 2 section and from the flue port 22 to the chimney connection port. 17 and on the bottom plate 11 of the flue S.

Therefore, after using the stove (usually when using the stove again the next day due to problems with cleaning up after the fire), if only the vertical main combustion chamber 2 is horizontally rotated in the rotatable direction, the same An ash scraping plate 21 integrally formed at the bottom of the combustion chamber 2 extends from the partition plate 18 to the chimney connection port 17 and then to the flue opening 22 via the flue S, that is, the flow is completely opposite to the smoke flow. The top of the bottom plate 11 is shallowly exhausted by rotating in the direction, and the ash and other cinders remaining on the bottom plate 11 are dropped into the ash collecting box 3, and the top of the bottom plate 11 is thoroughly cleaned.

After that, rotate the main combustion chamber 2 in the opposite direction to return it to its original state, pull out the ash collecting box 3, dispose of the ash and other slag as appropriate, and use it again as the original stove. be able to.

As described above, the household stove of this invention looks like a convection kerosene stove with a tank at the bottom, giving it the image of a conventional solid fuel stove. Insert your hand or a cleaning tool inside the combustion chamber to improve combustion efficiency by acting as a flue and to clean out ash and other cinders remaining inside the vertical main combustion chamber by means of rotation. Therefore, it is extremely hygienic and easy to handle, and it is extremely economical as it has a simple structure and can be provided at low cost, and can use inexpensive fuel. It can be used as a household stove.
