Abstract

PURPOSE:To prevent a bad smell, soots and carbon monoxide gas from generating at the time of fire extinction by a method wherein in a space between a wick guiding path and upwardly connected to a fixed combustion chamber, a free movable shutter in back and forth direction is provided. CONSTITUTION:During burning operation, a shutter 12 makes in withdrawal position so that a wick 1 may be moved upwardly by use of a knob for sliding a wick 1, and its tip-end is exposed to the lower side of the fixed combustion chamber 8. At the time of flame out, the knob for sliding the wick 1 up-and-down is rotated reversely to slide the wick downwardly, simultaneously, the shutter 12 is moved forth for obtaining a quicker flame out. In case of the flame out, there is neither any gap produced around the shutter nor any abnormal combustion due to bringing in an excess air generated, therefore, an instantaneous flame out may be possible, further, the upper and the lower surfaces of the shutter 12 are closely connected with the fixed wick guiding path 6 and with the fixed combustion chamber 8, besides, it is tightly hold by spacers 7 in a lateral side and three sides of rear surfaces, in addition, its front surface is clogged by itself, therefore, there is no possibility to leak out gas from the wick 1. Accordingly, after the wick path has been shut off by the shutter 12, no gas vapor is existed in its upper side, thereby, a bad smell and carbon monoxide gas may be completely eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wick-type oil combustor used in heating, space heating, drying equipment, and the like.

Conventional Technology As a fire extinguishing method for a wick-type oil combustor, various conventional methods have been used to cover the upper part of the wick using a shutter. Specifically, ■ A method of lifting the combustion tube and covering the top surface of the fire pan on which the combustion tube was placed with a shutter; ■ A method of providing a shutter that forms part of the combustion chamber wall when the combustion chamber is evacuated and covers the top surface of the fire pan when the combustion chamber is moved out. Methods such as ■ A method in which a shutter provided movably in the middle of the guide path covers the upper surface of the lowered lamp wick. Problems to be Solved by the Invention In the above-mentioned conventional configuration, there is no problem with the odor and There is a problem in that the generation of carbon oxide or soot cannot be completely prevented. This is due to the following reason.

That is, when the fire pan on which the combustion tube is placed is covered with a shutter as in the example of (1) or (2) above, a transient state of incomplete combustion occurs during the transition from the combustion state to extinguishment. In example ①, the combustion tube must be lifted up before the shutter is advanced, and at this time a large amount of air flows into the gap created between the fire pan and the lower end of the combustion tube. Since the shutter, which was part of the wall, comes loose and moves forward, it also creates a gap, which causes air to flow in. As a result, abnormal combustion occurs near the lamp wick, producing soot, or the combustion reaction is interrupted due to excessive air cooling, producing aldehydes as reaction intermediates that cause a significant odor, or -carbon oxides. Even though it only lasts for a short time, it causes unpleasant and unsafe phenomena such as the discharge of gas. In addition, in both cases, the shutter only slides into contact with the top surface of the fire pan, making it difficult to achieve airtightness, and even after the flame is extinguished, the fuel gas vaporized by the heat retained in the wick rises through the gap in the shutter section, causing contact with the high-temperature combustion chamber wall. This has the drawback of causing partial oxidation on contact, prolonging the generation of foul odors and carbon monoxide.

In addition, in the example of ■, the flame is extinguished by 4 as the wick falls, and the above ■
As usual, abnormal combustion caused by excess air can be avoided, and since the wick guide path is shielded, the airtightness is relatively good, and most of the vaporization of fuel from the wick can be shielded. Fuel adheres to the core guide path wall, and the fuel adhered to the top of the shutter gradually vaporizes even after the shutter is closed, and this rises and comes into contact with the high-temperature combustion chamber wall.
As mentioned above, it was impossible to completely suppress the generation of bad odors and carbon monoxide.

The present invention solves the above-mentioned conventional drawbacks, and configures a shutter with high airtightness to quickly extinguish the flame without causing an abnormal combustion state, and prevent the rise of fuel gas after the flame is extinguished.
The aim is to avoid the generation of odors, soot and carbon monoxide when extinguishing fires.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide a shutter that can move forward and backward between the guidance path and the fixed combustion chamber connected above the guidance path.

By using the above means, by advancing the shutter as the wick falls and shielding the guide surface, the flame can be quickly extinguished without abnormal combustion due to excess air, and the leakage of fuel gas and vaporization of attached fuel after the shutter is shielded can be prevented. The generation of foul odors and carbon monoxide can be almost completely prevented.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. In Fig. 1, 1 is a flat lamp wick, and the pinion 3 and the wick 1 are interlocked with each other by turning the wick up and down knobs 20 times.
It moves up and down by engaging with the rack 4 attached to it. 5
is a tank. The upper part of the tank S is provided with a guiding path 6 for holding and sliding the lamp wick 1, and a flat fixed combustion chamber 8 is fixedly connected to the wick guiding path e via a spacer 7. A similarly flat-shaped combustion cylinder 9 is placed on the fixed combustion chamber 8, and the outside is surrounded by an outer cylinder 10.
is a frame on which the outer cylinder 10 is placed; the fixed combustion chamber 8 and the combustion cylinder 9 are provided with a large number of air holes 8a and 9a, respectively, and a glass plate 10a is provided at the upper front of the outer cylinder 10. It is attached.

Here, a spacer 7 is provided between the guiding path 6 and the fixed combustion chamber 8.
A shutter 12 is provided which is surrounded on three sides, lateral and rear, and is movable forward and backward. In addition, the upper end of the upright part of the guide path 6 is connected to the lamp wick 1.
It is provided with a bulged portion 6a whose width is enlarged so as not to come into contact with.

Further, an ignition port 8b is opened in the center of the front surface of the fixed combustion chamber 8, and an ignition heater 1 that can move forward and backward faces the ignition port 8b.
3 is attached to the pedestal 11.

The ignition port 8b has a lid 8 having a curved operating rod 8C at the end.
The lid body 8d is configured to be opened and closed by sliding movement between the guide 14, which moves forward and backward at the same time as the ignition heater 13, and the operating rod 8C.

Next, the effect will be explained. During combustion, the shutter 12 is retracted and the wick 1 is raised by the wick up/down knob 2 to expose the tip to the lower part of the fixed combustion chamber 8.

The fuel is vaporized from the lamp wick 1 and then moved to the fixed combustion chamber 8 and the combustion tube 9.
Combustion occurs within the combustion chamber while receiving air supply from the air holes 8a and 9a.

When extinguishing the fire, the wick up and down knob 2 is reversed to lower the wick 1 and advance the shutter 12 to quickly extinguish the flame. At this time, no gap is created in the vicinity of the shutter 12, and the flame can be extinguished instantly without abnormal combustion caused by excessive air inflow as in the conventional case. In addition, the shutter 12 is in close contact with the fixed window guide path 6 and the fixed combustion chamber 8 on its upper and lower surfaces, is surrounded by spacers 7 on three sides and rear sides, and is closed by itself on the front side, so that the vaporized fuel from the lamp wick 11 remains in close contact with the fixed combustion chamber 8. No gas leaks upwards. Therefore, after the shutter 12 is closed, there is no fuel gas above the shutter 12, and the generation of odor and carbon monoxide can be completely prevented. Therefore, it is possible to extinguish fire safely and comfortably.

By the way, when the shirt starter 12 is shielded, the fuel continues to vaporize due to the heat retained in the lamp wick 11 itself;
Condensation occurs on the lower surface of 2 or the side wall of the core guide path 6 and reliquefies. Here, since the bulging part 6a is provided at the upper end of the upright part of the window guide path 6, the dew condensed fuel on the lower surface of the shirt starter 12 quickly flows down to this bulging part, and leaks out through the lower surface of the shirt starter 12. This can be avoided. Also, even during combustion, the wick 1
No fuel leaks from 1 to the upper plane of the window guide path 6,
It is also possible to prevent wetting of the surrounding area, which causes fuel to ooze out and fuel gas to rise after the shutter 12 is closed.

Here, the fixed combustion chamber 8 provided to improve the sealing performance of the shutter 12 can also be used for the fixed part of the ignition heater 13 and the opening of the ignition port 8b as in this embodiment. With or without the combustion tube 9 [Regardless of whether the ignition means can be fixed in the normal position, the ignition operation becomes more reliable, and at the same time, it is not necessary to lift the unstable flat-shaped combustion tube 9 or outer tube 1o to ignite. Safe ignition operation can be obtained.

The operation during ignition is as follows. As shown in FIG. 2, when the ignition heater 13 is advanced as shown by arrow A with the lamp wick 1 raised, the guide 14 also moves forward at the same time, and the curved operating rod 8c that fits into the guide 14 moves forward as shown by arrow B. Moving. Therefore, the lid 8d rotates as shown by the arrow C, and the ignition port 8b of the fixed combustion chamber 8 is exposed. The ignition heater 13 is inserted here and the lamp wick 1 is ignited.

In this way, ignition can be carried out safely and reliably without lifting the combustion tube 9, and since the ignition port 8b can also be set at any position, it is also possible to ignite at an intermediate position of the full length of the wick 11, so that the flame reaches the full length, so-called. It also shortens the firing time, and the unstable transient combustion state that leads to stable combustion can also be shortened.

Effects of the Invention By providing a shutter that can move forward and backward between a fixed window guide path and a fixed combustion chamber, the present invention can extinguish the flame quickly without abnormal combustion, and also prevents the rise of fuel gas after the flame has been extinguished. It completely shields the fire and prevents the generation of bad odors and carbon monoxide when extinguishing a fire, allowing for quick, safe and comfortable fire extinguishment.

Furthermore, since it has a fixed combustion chamber, it is possible to mount the ignition heater in a fixed manner, and it is possible to reliably ignite the combustion chamber without lifting the unstable flat combustion cylinder.
