Description

Description: TECHNICAL FIELD The present invention relates to an oil combustor, and particularly to prevent incomplete combustion gas having an odor rising in a combustion cylinder from leaking to the outside. It relates to the oil combustor.

[Prior Art] FIG. 12 is a half sectional view of a conventional oil combustor such as an oil stove.

The oil stove basically comprises a combustion cylinder 4 and a combustor tank 6. The combustion cylinder 4 has a single or a plurality of cylinders 4a. A wick 5 is installed in the combustion tank 6. Reference numeral 7 is a heater for igniting the wick 5.

 Next, the operation will be described.

When using an oil stove, first the equipped wick 5 in the combustor tank 6 is raised to the position of the dotted line. Then, the heater 7 is energized. When the heater 7 is energized, the heater 7
Becomes high temperature and ignites the wick 5 which has sufficiently absorbed the burning kerosene. The fire ignited by the heater 7 then goes around the entire wick 5, and the entire wick 5 is ignited.

[Problems to be Solved by the Invention] The conventional oil stove is configured as described above.
However, the gas generated immediately after ignition is not completely burned because the temperature of the combustion cylinder 4 has not risen sufficiently. Therefore, this incomplete combustion gas passes between single or plural cylinders 4a constituting the combustion cylinder 4 in a state accompanied by an odor, and escapes from the upper portion of the combustion cylinder 4 (the state is shown in the figure. Indicated by the arrow). This incompletely combusted gas has an unpleasant odor and has a problem that it gives an oil stove user an unpleasant feeling.

The present invention has been made to solve the above problems, and provides an oil combustor in which an incomplete combustion gas having an odor rising in a combustion cylinder is prevented from leaking to the outside. The purpose is to

[Means for Solving the Problems] The present invention is directed to a combustion cylinder, a wick to be ignited provided in the combustion cylinder, and a position provided in the combustion cylinder and higher than the wick. The suction cylinder having one end positioned and the other end sucking out the incomplete combustion gas sucked from the one end, and the incomplete combustion gas rising in the combustion cylinder Suction means for operating for a fixed time in conjunction with an ignition operation for sucking in from one end of the suction cylinder and discharging from the other end, and gas storage means for storing incomplete combustion gas sucked by the suction means Is equipped with.

[Operation] Since one end of the suction cylinder is located at a position higher than the core, the incomplete combustion gas having an odor rising in the combustion cylinder is sucked from the one end. Since the incomplete combustion gas sucked into the cylinder and sucked by the suction means from the other end of the suction cylinder is stored in the gas storage means,
Incomplete combustion gas with odor does not leak outside.

EXAMPLES Examples of the present invention will be described below with reference to the drawings.
Before that, first to third embodiments which are the basis of the present invention will be described with reference to FIGS. 1 to 3.

The first embodiment shown in FIG. 1 is the twelfth embodiment except for the following points.
This is the same as the conventional example shown in the figure, and corresponding parts are designated by the same reference numerals, and description of the configuration thereof is omitted. The difference from the conventional example is that a suction cylinder 1 for sucking incomplete combustion gas having an odor rising in the combustion cylinder 4 is provided in the combustion cylinder 4. The operation of the first embodiment will be described.

When the oil stove is ignited, the wick 5 installed in the combustion tank 6 is raised to the position shown by the dotted line in the figure.
After that, the heater 7 is energized. When the heater 7 is energized, the heater 7 becomes hot and ignites the wick 5 which has sufficiently absorbed the kerosene. After that, the fire generated by the heater 7 goes around the entire wick 5, and the temperature of the combustion cylinder 4 gradually rises to complete combustion. However, as described above, the temperature of the combustion cylinder 4 is not sufficiently high at the initial stage of ignition. Therefore, the gas generated in the vicinity of the wick 5 is an incomplete combustion gas and is accompanied by odor. In the conventional device, the incompletely combusted gas leaked from the upper side of the combustion cylinder 4 to the outside, which gave the user of the oil stove a discomfort. However, in the oil stove according to the embodiment, since the combustion cylinder 4 is provided with the suction cylinder 1 for sucking in the incomplete combustion gas having the odor that rises in the combustion cylinder 4, the inside of the combustion cylinder 4 rises. The incomplete combustion gas having an odor coming in is sucked into the suction cylinder 1 as indicated by an arrow in the figure, and does not leak to the outside.

FIG. 2 is a half sectional view of the second embodiment. In the first embodiment, the incompletely combusted gas having an odor is discharged from above the cylinder 4a, and the gas discharged from above the cylinder 4a is sucked by the suction cylinder 1. However, in the second embodiment, the side wall of the cylinder 4a is provided with an opening, and the incomplete combustion gas is discharged from the opening. Then, the incomplete combustion gas that has come out from this opening is sucked by the suction cylinder 1. Even with such a configuration, the same effect as that of the first embodiment can be realized.

FIG. 3 is a half sectional view of the third embodiment. The difference from the second embodiment is that the size of the suction cylinder 1 is set to a size that can be accommodated in the combustion cylinder 4, the extension pipe 8 is connected, and the inside of the suction pipe 1 is connected by the extension pipe 8. It is configured so that the incomplete combustion gas passing therethrough can be taken out.
With such a configuration, the suction cylinder 1 can be separated as one component of the combustion cylinder 4. Therefore, the combustion cylinder 4 can be easily attached to and detached from the combustion tank 6, which is convenient for cleaning.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 11.

FIG. 4 is a half sectional view of the first embodiment of the present invention. The petroleum combustor according to the first embodiment is provided in a combustion cylinder 4, and a suction cylinder 1 for sucking incomplete combustion gas having an odor rising in the combustion cylinder 4, and the suction cylinder. A suction unit 2 which is attached to the suction unit 1 to suck the incomplete combustion gas into the suction cylinder 1, and the suction unit 2.
It is equipped with a gas accumulating container 3 for accommodating the incomplete combustion gas having the odor which is attached to the exhaust port 2a, is sucked by the suction device 2 and passes through the suction cylinder 1. A motor with a fan 20 is attached to the discharge port 2a of the suction device 2.
30 are installed.

Next, the operation of the oil combustor according to the first embodiment of the present invention will be described.

At the time of ignition, since the temperature of the combustion cylinder 4 is not sufficiently high, the gas generated near the wick 5 is an incomplete combustion gas and is accompanied by odor. This incomplete combustion gas rises in the combustion cylinder 4 and tries to exit from the upper part of the combustion cylinder 4. At this time, when the motor 30 in the suction device 2 is operated, the incomplete combustion gas accompanied by odor is sucked into the suction cylinder 1 as shown by the arrow in the figure, and passes through the suction device 2 to accumulate gas. Container 3
Is taken in. Therefore, incomplete combustion gas having odor does not leak outside. Here, the gas storage container 3
Is, for example, a vinyl bag, and when it is initially deflated, it is possible to take in incomplete combustion gas therein.

FIG. 5 is a half sectional view of the second embodiment of the present invention.
The difference from the first embodiment is that an opening is provided in the side wall of the cylinder 4a so that the incomplete combustion gas is discharged from this opening, and the incomplete combustion gas discharged from this opening is sucked into the suction cylinder 1 It is configured to be taken in. With such a configuration, the same effect as that of the first embodiment can be realized.

FIG. 6 is a half sectional view of the third embodiment of the present invention.
The embodiment shown in FIG. 6 is the same as the first embodiment except for the following points, and the corresponding portions are given the same reference numerals,
The description is omitted. The difference from the first embodiment is that the size of the suction cylinder 1 is such that it can be accommodated in the combustion cylinder 4, and the lower end of this suction cylinder 1 is connected by extension pipes 8a, 8b, 8c. The point is that the suction device 2 is connected, and the suction pipe 2 and the gas storage container 3 are also connected by extension pipes 8d and 8e. With such a configuration, the extension pipes can be separated from each other at the connecting portion, which is convenient for cleaning or the like.
Needless to say, even with such a configuration, the same effect as that of the first embodiment can be realized.

FIG. 7 is a half sectional view of the fourth embodiment of the present invention.
The suction cylinder 1 is of a size that can be accommodated in the combustion cylinder 4, and is connected to the suction device 2 by using extension pipes 8a, 8b, 8c. A gas storage container 3 is connected to the discharge port 2a of the suction device 2. The feature of this embodiment is that the side wall of the suction cylinder 1 and the side wall of the cylinder 4a are provided with openings, respectively, and the incomplete combustion gas is sucked through these openings. Even with such a configuration, the same effect as that of the above-described embodiment is realized.

FIG. 8 is a half sectional view of the fifth embodiment of the present invention.
The petroleum combustor according to the fifth embodiment is provided in a combustion cylinder 4, and a suction cylinder 1 for sucking incomplete combustion gas having an odor rising in the combustion cylinder 4, and the suction cylinder. 1
And a space 9a is provided between the gas storage container 3 and a gas storage container 3 for storing the incomplete combustion gas sucked into the suction cylinder 1, and the space 9a is provided between the gas storage container 3 and the gas storage container 3 for storing the gas. It surrounds the container and protects the gas storage container 3.
An outer box 9 for inflating the gas storage container by reducing the pressure in the space 9a, and an outer box 9 attached to the outer box 9 and provided between the outer box 9 and the gas storage container 3 The pressure reducing device 10 is a suction unit for reducing the pressure in the space 9a.

Next, the operation of the oil combustor according to the fifth embodiment will be described.

As described above, since the temperature of the combustion cylinder 4 is not sufficiently high at the initial stage of ignition, the gas generated in the vicinity of the wick 5 is an incomplete combustion gas and is accompanied by odor. When the incomplete combustion gas rises in the combustion cylinder 4 and tries to come out from above, the decompressor 10 is operated. Then, the space part of the outer box 9
The internal pressure of 9a decreases. Therefore, the gas storage container 3 inside the outer box 9 is initially deflated, but gradually expands.
Therefore, the suction cylinder 1 produces a suction force.
Due to this suction force, the incomplete combustion gas is sucked and confined in the gas storage container 3. In addition, this outer box 9
In addition to the above-mentioned function, it also functions to protect the gas storage container 3. That is, in the first, second, third, and fourth examples, the gas storage container 3 was exposed.
Since this gas storage container 3 is made of a relatively thin material such as polyethylene, if an external force is applied even a little,
There was a problem that it was broken and the ability to contain incomplete combustion gas was lost. However, with the configuration as in the fifth embodiment, since the gas storage container 3 is protected by the outer box 9, the above-mentioned drawbacks are eliminated.

FIG. 9 is a half sectional view of the sixth embodiment of the present invention.
The embodiment shown in FIG. 9 is the same as the embodiment shown in FIG. 8 except for the following points. That is, the difference from the embodiment shown in FIG. 8 is that the suction cylinder 1 is of a size that can be accommodated in the combustion cylinder 4, and is connected to the gas storage container 3 using the extension pipes 8a and 8b. The connection point between the outer box 9 and the pressure reducer 10 is also a connecting pipe 11. With this configuration,
The extension pipe or the connecting pipe can be disconnected at the connecting portion, which is convenient for cleaning. Since the other points are similar to those of the fifth embodiment, the same effect as that of the fifth embodiment is realized.

FIG. 10 is a half sectional view of the seventh embodiment of the present invention. The petroleum combustor according to the seventh embodiment is provided in a combustion cylinder 4, and a suction cylinder 1 for sucking an incomplete combustion gas having an odor rising in the combustion cylinder 4, and the suction cylinder. 1, a suction device 2 that is a suction means for sucking the incomplete combustion gas into the suction cylinder, and a discharge port 2a of the suction device 2 that is sucked by the suction device 2 and used for the suction. It is connected to the gas storage container 3 for storing the incomplete combustion gas having the odor that has passed through the cylinder 1 and the suction device 2, and temporally manages the suction start and the suction end of the suction device 2. Equipped with type 8.

FIG. 11 is a half sectional view of the eighth embodiment of the present invention. The petroleum combustor according to the eighth embodiment is provided in a combustion cylinder 4, and a suction cylinder 1 for sucking an incomplete combustion gas having an odor rising in the combustion cylinder 4, and the suction cylinder. 1. A space 9a is provided between the gas storage container 3 and a gas storage container 3 that is provided in the lower part of FIG. 1 and stores the incomplete combustion gas that has been sucked into the suction cylinder 1. An outer box 9 for protecting the gas storage container 3 by enclosing the storage container 3 and for inflating the gas storage container by reducing the pressure in the space 9a.
The decompressor 10, which is attached to the outer box 9 and serves as suction means for reducing the pressure in the space 9a provided between the outer box 9 and the gas storage container 3, and the decompressor 10. It is equipped with a timer 8 for temporally managing the start and end of the pressure reduction of the pressure reducer 10. In the seventh and eighth embodiments, the type 8 is provided in the circuit connecting the power supply 11 and the motor 20. In the above-described first to sixth embodiments, the timer 8 for temporally managing and operating the suction device 2 and the pressure reducing device 10 is not used. Therefore, there are some drawbacks described below. That is, as described above, since the suction device 2 and the decompressor 10 are for sucking incomplete combustion gas, even if they are operated before the wick 5 is ignited, only unnecessary electric power is used. In addition, if it is operated for a long time after ignition, the combustion cylinder 4
The balance of combustion inside is lost, and even the vapor of kerosene, which is fuel, is sucked into the suction cylinder 1. The above drawbacks are solved by providing the timer 8. next,
The operation will be described with reference to FIG.

During ignition, the wick 5 rises to the position indicated by the dotted line, and the heater 7 is energized. Then, the timer 8 is set to turn on at the same time as the energization of the heater 7 or a few seconds later.
Then, after the set time, the suction device 2 is supplied with power from the power source 11 and starts operating. Then, a suction force is generated in the suction cylinder 1, and the suction cylinder 1 starts to absorb the incomplete combustion gas having odor. Further, after the timer 8 is turned on, it is set to be turned off after a predetermined time. Then, the power supply from the power supply 11 is cut off after the elapse of the set time. Then, the suction device 2 that has sucked the incomplete combustion gas having the odor is stopped. In this way, unnecessary consumption of electric power by operating the suction device 2 and the pressure reducer 10 before ignition can be suppressed as much as possible. Further, since the suction is stopped after a fixed time, the suction is continued for a long time after ignition, the balance of combustion in the combustion cylinder 4 is lost, and the vapor of kerosene as fuel is sucked into the suction cylinder 1. Problems are also solved.

 Even in the eighth embodiment, the effect is the same.

Although it is common to all of the above-described embodiments, the cross-sectional shape of the suction cylinder 1 and the extension tubes 8a, 8b, 8c need not be circular and may be other shapes.

Further, in the above-mentioned embodiment, the case where the oil stove is ignited only has been described, but the present invention is not limited to this, and the invention can be used only when ignited and extinguished or when extinguished. That is, suppose that the oil stove is extinguished, that is, the wick 5 that has been in the position of the dotted line until then falls to the position of the solid line and is extinguished. At that time, the kerosene vapor in the vicinity of the wick 5 rises in the combustion cylinder 4, but the combustion cylinder 4 gradually disappears by extinguishing the fire, so the kerosene vapor is not completely decomposed and has an odor. It becomes combustion gas. Therefore, the suction cylinder 1 in the combustion cylinder 4
If this is sucked in, the odor at the time of extinguishing can be reduced.

As described above, the present invention can be implemented in various other forms without departing from the spirit or the main characteristics. Therefore, the above embodiments are merely examples in all respects, and should not be construed as restrictive. The scope of the present invention is defined by the claims and is not bound by the text of the specification. Furthermore, all modifications and changes belonging to the equivalent scope of the claims are within the scope of the present invention.

[Effects of the Invention] As described above, according to the petroleum combustor according to the present invention, since one end of the suction cylinder is positioned higher than the wick, the oil is generated from the wick immediately after ignition. The incomplete combustion gas having an odor that rises in the combustion cylinder is sucked into the suction cylinder from one end of the suction cylinder and sucked out by the suction means from the other end of the suction cylinder. The incomplete combustion gas having odor generated at the time of ignition can be surely prevented from leaking to the outside with a simple structure, and the user of the oil combustor is incomplete. It is possible to reliably prevent inhalation of the odor of the combustion gas to cause discomfort.
