Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil combustor having a structure in which a cylindrical lamp wick can be divided, and more specifically, the invention is constructed so that the upper part of the lamp wick, which is easily worn out and deformed, can be easily replaced. This is what I did.

Conventionally, oil burners have been in extremely high demand because of their low fuel consumption compared to heating appliances that use other heat sources such as electricity and gas combustion appliances.

However, the distribution channels and storage containers for white kerosene are not sufficiently managed, resulting in impure oil (white kerosene mixed with oils that have been refined at different temperatures, e.g. white kerosene mixed with light oil, salad oil, oil, etc.) and denatured oil. (This refers to white kerosene whose quality has deteriorated due to oxidation, etc.) is used without being able to judge the oil, resulting in poor combustion due to tar and other impurities adhering to the wick, poor wick up/down, indigestion, etc. have a problem.

It is well known in the industry that these problems are inevitable for combustion appliances that use lamp wicks, and cannot be solved.

The present invention overcomes this drawback, does not require any other technology, is inexpensive, and can easily achieve normal combustion conditions.

Conventional oil combustor lamp wicks were used as a single unit without being separated.

Therefore, if the above problem occurs due to impurities, deteriorated oil, etc., many parts such as the heating plate and wick outer cylinder must be removed in order to replace the wick, and at this time, the entire wick must be replaced. This made the process inconvenient for the user, and required many dogs to dispose of it.

The present invention will be explained below with reference to the drawings showing one embodiment thereof.

In FIGS. 1 to 3, 1 is a tank loaded with white kerosene, and 2 is a core outer cylinder erected on the upper surface of the tank 1.

3 is a core guide tube provided inside the core outer shell 2; 4 is a combustion tube consisting of an inner and outer flame tube 5 and 6; the lower part of the inner and outer flame tubes 5 and 6, which have many small holes, is a core guide tube; They are removably mounted on the upper ends of the tube 3 and the outer tube 2, respectively.

7 is a heat shield plate, and 8 is a net provided above the combustion tube 4.

Reference numeral 9 denotes a lamp wick that is movable up and down between the wick guide tube 3 and the wick outer tube 2, and when burning, the upper end of the wick 9 is placed on the fire pan surface 0-0'.
It protrudes above the fire plate, and when extinguishing the fire, its upper end is lowered below the fire pan surface 〇10′.

Reference numeral 10 designates a small hole for introducing cold air provided in a portion of the wick guide tube 3 below the fire pan surface 0-07, and when extinguishing the lamp, cold air is sent above the wick 9 to suppress vaporization of oil and quickly extinguish the fire. let

Next, the structure of the lamp wick 9 will be described.

The cylindrical lamp wick 9 is divided into a lower oil suction lamp wick 9a and an upper combustion lamp wick 9b, and the inner surface of the oil suction lamp 9a, that is, the surface on the wick guide tube 3 side, A lower cylindrical body 11a made of metal or resin is fixed, and a combustion lamp wick 9
An upper cylinder 1lb made of metal and having high heat resistance is fixed to the inner surface of b.

A groove 12 is formed on the inner surface of the lower end of the upper cylinder 1lb, and a protrusion 13 provided on the upper end of the lower cylinder 11a engages with this groove 12, and the groove 12 extends somewhat in the circumferential direction. Due to their length, both cylinders 11a and 1lb are connected to a bayonet.

As a result, the lamp wicks 9a and 9b are joined together without any gap between them, and the combustion lamp 9b is filled with oil and becomes ready for combustion.

The outer surface of the combustion wick 9b and the oil suction wick 9a are in contact with the inner surface of the wick outer cylinder 2, as can be seen from FIG.

What is shown in FIG. 4 is the upper cylindrical body 1lb and the lower cylindrical body 1.
The connection with 1a is performed by screwing, and 14.
15 indicates each threaded portion.

According to the above configuration, when the lamp wick 9, especially the combustion lamp 9b, is consumed or deformed due to combustion, or when tar or the like adheres to the combustion lamp 9b, the combustion tube 4 is removed from the wick guide tube 3 and the wick. By removing it from the tube 2, only the combustion wick 9b can be removed from the oil suction wick 9a, and compared to the conventional case where the entire wick is replaced by removing the heat shield etc. It is easy to attach and detach, and the wick itself can be small, reducing the amount of materials used.

Further, the lamp wicks 9a, 9b are fixed to the cylinders 11a, 1lb, so that the lamp wicks 9a, sb are not deformed during the above-mentioned attachment/detachment operation, and the lamp wicks 9a, 9b can be easily handled.

As can be seen from the above embodiments, the present invention can be applied to
Divided into a lower combustion wick and an oil suction wick,
Since both lamp wicks are installed on the wick guide cylinder side and are removably connected at the lower cylinder body, when the combustion wick deteriorates, only the combustion wick needs to be replaced, which is a very low burden. Also, the sides of the wick outer tubes of the upper and lower combustion wicks and oil suction wicks are in contact with the wick outer tube, so the inside of the tank and the combustion tube are isolated during this time, preventing vaporized gas from leaking from the tank. There is no oil leakage when falling, and the same leakage phenomenon occurs from the core guide cylinder and the top.
This reduces the risk of odor and flames, since the lower cylinder moves up and down along the core guide cylinder, and is removably connected to the lower cylinder. The upper cylinder does not come into contact with the wick guide cylinder when moving up and down, so the upper cylinder and the combustion wick may come off when moving up and down.
There will be no contact failure with the lower oil suction wick, and a stable supply of oil from the oil suction wick to the combustion wick will occur, resulting in stable combustion operation.
