Abstract

PURPOSE:To prevent oil from flowing out of a stove, even if a kerosene stove is turned over, and to enable to extinguish fire in a short time, by providing a notched part, at least to a part of combustion main wick on the side contacting with a wick outer cylinder. CONSTITUTION:When a kerosene stove is turned over, kerosene oil filling up the gap between a combustion main wick 4c and a wick guide cylinder 2 flows into a notched part 16, provided between an ignition and flame-spreading wick 4b and a wick outer cylinder. The oil flowing into the notched part 16 cannot flow out to the side of a combustion tray 17, because surface tension is produced between the ignition and flame-spreading wick 4b and the wick outer cylinder 3. With such an arrangement, flames can be extinguished in a short time, and safety characteristics is improved in the kerosene stove.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil burning device that burns oil using a wick, such as an oil stove, an oil stove, and an oil-fan heater. The purpose is to achieve this goal.

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 the wick is placed above the wick.

The structure is such that combustion and extinguishing are performed by the downward movement. In order to prevent this wick from burning out due to the heat of combustion, a glass wick is usually used as a non-combustible wick in the combustion part.
Since this glass core has insufficient durability against degraded oil, etc., a core made of highly durable ceramic fiber, etc.
-Las ceramic core has come to be used.

However, this porous ceramic wick has a high kerosene content, so it is always saturated, and when an oil combustion device 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 [combustion upper core] provided between the core guide tube 2 and the core outer tube 3 so as to be able to move up and down is a metal core. Since it is held by the holder 16, the space between the wick guide tube 2 and the upper combustion wick 4C is filled with kerosene to a distance of 9 meters. And if the oil combustion equipment falls over, the combustion upper wick 4C
Due to the action of the vibration fire extinguishing system (not shown), the contaminants sink into the space between the core guide tube 2 and the outer core tube 3 and extinguish the fire. The 3 pages of kerosene that had been in the fire flowed out to the fire pan 17 side and continued 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 core outer cylinder and a core guide cylinder, a main combustion window made of a material with high petroleum content such as porous ceramic in the combustion part of this wick, and a wick of this main combustion window. The above-mentioned drawbacks of the conventional combustion engine are solved by attaching a core holder to the guide cylinder side and providing a notch in at least a portion of the main combustion window that contacts the core 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 provided between the wick guide tube 2 and the core outer tube 3 so as to be movable up and down, and 6 is a cylindrical lamp wick that covers the upper part of the wick 4! Open-5
8-996O4 (just in case) This is a combustion tube placed on the core guide tube 2 and the core outer tube 3.

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 ventilation hole 1o of the ejector part 9 as shown by the arrow A, so that the guide cylinder 1
The air inside 1 is sucked up as shown by the 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 the arrow. The exhaust gas generated by the combustion is sucked up by the air (arrow A) supplied from the fan 6, mixed with cold air, and then supplied into the room from the outlet 14 provided in the exterior body 7 as warm air.

Figure 2 is an enlarged view showing the main parts of the oil combustion device.The lamp wick 4 has a suction part 4a made of water-repellent cotton or the like, an ignition wick 4b made of glass fiber, and a binder made of ceramic fiber. It consists of a hardened porous ceramic core 4'C (hereinafter referred to as the combustion main window) which is adhered or sewn together.

16 is the combustion main window 4C of the combustion part of the lamp wick 4 and the suction part 67;
-7. This is a cylindrical metal lead holder provided on the lead guide tube 2 side astride 4a. Reference numeral 16 denotes a notch provided in a part of the main combustion window 4c of the combustion section on the side in contact with the core outer cylinder 3. 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. A notch 16 provided in the main combustion window 4c between the main combustion window 4b and the core outer cylinder.
The kerosene that has flowed into the notch 16 has a surface tension between the ignition wick 4b and the wick outer cylinder 3, and the kerosene flows into the fire pan 1.
The fire will be extinguished in a short time because it will not flow out to side 7.

Note that the notch portion 16 of the main combustion window 4C may be provided in the front and rear directions if the oil combustion device is capable of falling over only in the front and rear directions, and ≠6. Takataki =
If there is a possibility of overturning the main combustion window 4c in the left and right direction, a notch 16 may be provided over the entire circumference of the main combustion window 4c.

As is clear from the above description, the oil combustion device of the present invention has a notch in at least a portion of the main combustion window that contacts the wick outer cylinder, so that even if the oil combustion device falls over, the wick remains intact. Since oil does not flow out from the combustion part, the fire can be extinguished in a short time, resulting in high safety and low cost.
