JPS62248923A - Malodor preventive device in kerosene stove - Google Patents

Abstract

PURPOSE:To prevent malodor generated upon combustion shutdcon from being dispersed by disposing a wick guide at the lower part of a combustion cylinder, providing horizontal shutter grooves in the wick guide, and mounting a shutter plate on the shutter groove in a manner freely moving, in a horizontal direction, into or out of the shutter groove. CONSTITUTION:An odor preventive shutter 17 moves along a shutter groove 18 horizontally at the upper end portion of a wick guide 9. A lever mechanism 20 for causing the shutter 17 to move in or out horizontally, is connected to an operating lever 14 by means of a wire 22, and is opened or closed in linkage with the vertical movement of a wick 11. The operating lever 14 is manipulated downward to firstly lower the wick 11 an to below the shutter 17 within the wick guide 9, and then the wire 22 is pulled to close the odor preventive shutter 17. By this procedure, air required for the combustion of the wick 11 is cut off and the flame of the wick 11 goes out. At the same time, the odor preventive shutter 17 cuts off a so-called malodor causeel by natural vaporization of kerosene.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a petroleum oil fuel cell in which a flat combustion cylinder is arranged in the vertical direction, and a flat wick is configured to be able to freely enter and exit from the lower part of the combustion cylinder from below. This invention relates to a deodorizing device for a stove.

[Prior art and its problems] Conventional kerosene stoves have a cylindrical combustion tube placed in front of the heat-reflecting surface, and a cylindrical wick that can freely enter and exit from the bottom of the combustion tube from below. A ring-shaped flame is formed inside.

Therefore, the area of the combustion tube that radiates heat directly to the front of the stove is reduced to half, and only the heat reflected on the reflective surface is released as radiation. However, this radiant heat also has a problem in that the heat is blocked in the part hidden behind the combustion tube, resulting in poor radiation efficiency.

Also, for a cylindrical combustion tube, the diameter of the combustion tube is l in the depth direction]
This has the disadvantage that the stove becomes larger, especially in the depth direction.

Additionally, kerosene stoves have the problem of emitting bad odors due to natural vaporization when not in use, especially when extinguishing a fire.

[Object of the present invention] The present invention has been proposed in view of the above points, and its main purpose is to arrange a flat combustion tube in the vertical direction, and insert a flat core into the lower part of the combustion tube from below. To prevent a kerosene stove configured to be freely accessible from producing a bad odor when not in use, especially when extinguishing a fire.

[Configuration of the present invention] In order to achieve the above object, the present invention employs the following configuration in a kerosene stove.

In a kerosene stove comprising a flat combustion tube arranged in the vertical direction, and a flat wick configured to freely move in and out from below in the lower part of the combustion tube, a wick guide is arranged below the combustion tube,
This deodorizing device for a kerosene stove has a structure in which a horizontal shutter groove is provided in the core guide and a shutter plate is attached to the shutter groove so as to be able to move in and out from the horizontal direction.

In the kerosene stove with the above structure, the wick is raised by operating the handle and ignited to form a linear flame within the combustion cylinder, and when not in use, the wick is lowered and the shutter plate is closed.

[Embodiment] The figure shows an embodiment of the kerosene stove according to the present invention, in which 1 is the stove body, 2 is a reflective surface, and 3 is a flat combustion tube arranged perpendicularly in front of the reflective surface 2. The combustion tube 3 consists of a heat-resistant glass 4, a heat collecting rod 5, and a combustion promotion plate 6 attached to the upper end.

Reference numeral 7 designates a device chamber formed between the combustion tube 3 and the fuel chamber 8, and the device chamber 7 includes a wick guide 9 communicating with the lower opening 3a of the combustion tube 3 and left and right 2. Places (
However, in the embodiment, the combustion tube is divided into two parts, so four guide slits 10 are cut in each part.

11 is a flat core whose lower part is immersed in the fuel chamber 8 and whose upper half extends into the core guide 9, and a rack 12 is attached to this core 11 at a position corresponding to the guide slit 10. The core 11 can be moved up and down by the rotation of the pinion 13 that meshes with the rack 12. 14 connects the binion 13 to a rack 15', a drive binion 15,
As an operating lever for rotating via the drive shaft 16,
It is used to take in and take out the core 11 and to open and close the deodorizing shutter 17.

17 is a shutter groove 1 at the upper end of the core guide 9.
This is a deodorizing shutter that goes in and out horizontally along 8.

Reference numeral 19 denotes an ignition heater placed on the deodorizing shutter 17 and facing near the upper end of the wick guide 9.
Reference numeral 9 can be moved in and out, and is powered by a dry cell battery (not shown), which is energized when ignited and produces a red flame.

In FIG. 2, the reference numeral 20 indicates the deodorizing shutter 17.
This lever mechanism 20 is connected to the operation lever 14 by a wire 22, and is opened and closed in conjunction with the vertical movement of the core 11.

That is, when the wire 22 is pulled by operating the operating lever 14, the deodorizing shutter 17 closes and the wire 22 is pulled.
It is configured to open when ′ is pulled.

Reference numeral 21 in the figure is a fuel tank.

Next, an example of the use of the above-mentioned kerosene stove will be explained.

First, when igniting, raise the operating lever 14 to pull the wire 27 and close the deodorizing shutter 17.
is opened, and at the same time, the rack 15' rises, driving the drive pinion 15, transmitting rotation from the drive shaft 16 to the pinion 13, sending the rack 12 upward, and moving the wick 11 within the lower part of the combustion tube 3 to the maximum position. The heating power is increased to the level, and the ignition heater 19 is energized to ignite the wick 19. Next, the wick 19 is operated to perform so-called heat power adjustment.

The flame ignited in this way rises in the combustion tube 3 while being flat, that is, at the end of autumn, and releases heat.

Next, extinguishing will be explained. This extinguishing is basically the reverse effect of the above-mentioned ignition, and first the wick 11 is lowered within the wick guide 9 and below the deodorizing shutter 17 by operating the other control lever 14 downward, and then the wire 22 to close the deodorizing shutter 17. In this way, core 11
The air necessary for combustion is cut off and the flame of the wick 11 is extinguished. At the same time, the deodorizing shutter 17 blocks out so-called bad odors caused by natural vaporization of petroleum.

[Effects of the present invention] Since the present invention has a flat combustion tube as described above, the heat radiation area is doubled, and at the same time, the radiant heat is not blocked.
Radiation efficiency is greatly improved.

Furthermore, since the combustion tube is flat, the width of the stove in the depth direction can be reduced.

In addition, the shutter plate has the effect of suppressing natural vaporization and preventing the release of bad odors, especially when extinguishing a fire.
