Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil combustion device that burns oil using a wick such as an oil stove, an oil stove, or an oil fan heater, and aims to shorten the extinguishing time when the oil combustion device falls over. The purpose is to

Generally, this type of oil combustion device has a wick that can move up and down between the wick outer tube and the wick guide tube, and above this wick,
The structure is such that combustion and extinguishing are performed by the downward motion. A glass wick is normally used as a non-combustible wick in the combustion part of this lamp wick to prevent it from burning out due to the heat of combustion, but this glass wick has insufficient durability against degraded oil, etc. Porous ceramic cores made of ceramic fibers and the like have come to be used.

However, this porous ceramic wick has a high kerosene content and is always saturated, so when the oil combustion equipment falls over, the kerosene filling the combustion part spills out and burns, so it takes a long time to extinguish the fire. It took a long time and was very dangerous.

To explain the overturned state of this oil combustion device using FIG. 3, the porous ceramic core 4c is provided between the core guide tube 2 and the core outer tube 3 so as to be vertically movable.
Since the [combustion main wick] is held by a metal wick holder 15, the space between the wick guide tube 2 and the combustion main wick 4c is filled with kerosene due to capillary action. If the oil combustion equipment falls over, the combustion main wick 4c
Due to the action of a vibration fire extinguishing system (not shown), it is thrown into the space between the core guide tube 2 and the core outer tube 3 to extinguish the fire. The kerosene that was being burned flows out to the fire pan 17 side and continues to burn.
Therefore, it took a long time to extinguish the fire.

The present invention provides a lamp wick that is movable up and down between a wick outer tube and a wick guide tube, and a combustion main wick made of a material with a high petroleum content such as porous ceramic is provided in the combustion part of this wick. The above-mentioned drawbacks of the conventional combustion engine are solved by attaching a wick holder to the guide cylinder side and providing a notch in at least a portion of the combustion main wick that is in contact with the wick outer cylinder side.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Note that the same members as in the conventional example will be described with the same reference numerals.

In FIG. 1, reference numeral 1 denotes a fuel tank of an oil combustion device, and kerosene used as an example of petroleum is stored in this fuel tank 1. 2 is a cylindrical core guide tube, and 3 is a cylindrical core outer tube. The core guide tube 2 and the core outer tube 3 are erected on the fuel tank 1.
4 is a cylindrical lamp wick that is vertically movable between the wick guide tube 2 and the outer core tube 3, and 5 is a combustion lamp placed on the wick guide tube 2 and the outer core tube 3 so as to cover the upper part of the wick 4. It is a cylinder. Reference numeral 6 denotes a fan, which sucks air through a suction port 8 provided in the exterior body 7, and the sucked air passes through the vent hole 10 of the ejector part 9 as shown by arrow A, so that the air inside the guide tube 11 is It is sucked up like an arrow. In other words, the air flow shown by arrow A acts as an ejector. Air necessary for combustion in the combustion tube 5 is sucked in and supplied from a combustion air suction port 13 provided in the bottom plate 12 as shown by arrow C. The exhaust gas generated by the combustion is sucked up by the air (arrow A) supplied from the fan 6, mixes with the cold air, and becomes warm air to the exterior body 7.
The air is supplied indoors from an outlet 14 provided in the air.

Figure 2 is an enlarged view showing the main parts of the oil combustion equipment.
The lamp wick 4 includes a suction part 4a made of water-repellent treated cotton or the like, an ignition wick 4b made of glass fiber, and a porous ceramic wick 4c (hereinafter referred to as the combustion main wick) made of ceramic fibers hardened with a binder. It is made up of things that are pasted or sewn together. 1
5 is the combustion main wick 4c of the combustion part of the lamp wick 4 and the suction part 4
This is a cylindrical metal lead holder provided on the lead guide tube 2 side astride a. 16 is the core outer cylinder 3
This is a notch provided in a part of the combustion main wick 4c of the combustion section on the side that is in contact with. Reference numeral 17 denotes a fire pan made up of a core guide tube 2 and a core outer tube 3.

If the oil combustion device is configured in this way, when the oil combustion device falls over as shown in FIG. 2, the kerosene filling between the combustion main wick 4c and the wick guide tube 2 will
Combustion main wick 4c between the ignition ignition wick 4b and the wick outer cylinder
A portion of the kerosene that has flowed into the notch 16 is absorbed by the ignition wick 4b, and the rest is absorbed by the ignition wick 4b.
Since the gap between the core and the outer cylinder 3 is narrowed by the fluff, surface tension is generated between the core and the outer cylinder 3 and the fire does not flow out to the fire pan 17 side, so the fire is extinguished in a short time. Ru.

Note that the notch portion 16 of the combustion main core 4c may be provided in the front and rear directions if the oil combustion device is such that the oil combustion device can only fall over in the front and rear directions; If there is a possibility of the main combustion core 4c falling over in the left and right direction, the notch 16 is placed around the entire circumference of the main combustion core 4c.
All you have to do is set it up.

As is clear from the above description, in the oil combustion device of the present invention, a cutout is provided in at least a part of the side of the combustion main wick in contact with the wick outer cylinder to expose the ignition ignition wick. Even if it does not have oil absorbing ability because of its high oil content, the oil wick does not leak out from the combustion part of the wick even if the oil burning device falls over due to the absorbing ability of the wick and the surface tension strengthening effect of the fluff. Therefore, the fire can be extinguished in a short time, resulting in high safety and low cost.
