Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wick-type oil-burning appliance.

Conventional structure and its problems A conventional kerosene stove extinguishes the fire by lowering the tip of the wick a between the wick guide tube b and the wick outer tube c, as shown in Figure 3.If the wick a is lowered all at once, extinguishes the fire instantly. However, even after the wick is extinguished, the wick guide tube b and the wick outer tube c remain at a high temperature, so raw gas is generated from the wick a, causing a problem in that an odor is generated when the lamp is extinguished.

Purpose of the invention The purpose of the invention is to solve the above problems and reduce the odor during extinguishing fires.

DESCRIPTION OF THE INVENTION In order to achieve the above object, the present invention completely burns the raw gas generated from the wick after extinguishing operation, thereby reducing the extinguishing odor.

As for its structure, an air hole is provided in the wick guide tube or the wick outer tube, and the ignition heater is also energized during extinguishing, making it easier to burn the raw gas generated from the wick when extinguishing.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to FIGS. 1 and 2. 1 is an outer flame cylinder having a plurality of combustion holes 2;
3 is an inner flame cylinder, which has a partition plate 4 and a flame expansion plate 5. 6
is the outer cylinder, and the inner flame cylinder 3 and the outer flame cylinder 1 are connected to the cross pin 7.
It is fixed at 8 is a wick guide tube that guides the vertical slide of the lamp wick 9; 10 is a wick outer tube;
An ignition heater 11 is provided above. The lamp wick 9 is provided with a notch 12 in a part of the side facing the ignition heater 11. Also, core outer cylinder 1
0 is provided with an air hole 13 that communicates with the notch 12 of the lamp wick 9 when the lamp wick 9 is lowered. This air hole 13 is opened so as to communicate with an upper air layer 15 of the fuel tank 14.

Consisting of the above configuration, in the above configuration, the lamp wick 9
is raised to the state shown by the two-dot chain line in FIG. 1, and ignited by the ignition heater 11 to continue combustion. During combustion, the lamp wick 9, wick guide tube 8, wick outer tube 10, and fuel tank 14
Since the temperature of the fuel inside has risen, when extinguishing the lamp wick 9 is lowered as shown by the solid line in FIG. It is reburned by Also, when the wick 9 descends all at once, the inside of the fuel tank 14 becomes pressurized momentarily, so
The raw gas generated in the fuel tank 14 escapes through the air hole 13 of the outer wick tube 10 and is burned together with the raw gas generated from the tip of the wick 9.

The raw gas generated from the tip of the wick 9 gradually decreases and extinguishes naturally, but a part of the wick on the side facing the ignition heater 11 is cut out and communicates with the space 15 of the fuel tank 14. Since the air hole 13 is provided to allow a suitable amount of air to flow through, it acts as a pilot point to completely burn out the residual gas generated from the wick 9, and the wick 9 fuel tank 1
When the residual gas generated from 4 becomes less, the fire will naturally extinguish. In this way, the raw gas after the extinguishing operation is completely combusted, resulting in almost no odor.

Furthermore, if the air hole 13 is communicated with the fuel tank 14 as in this embodiment, even if the oil contained in the wick 9 evaporates from the air hole 13 during combustion, it will not be dissipated into the atmosphere. It is also possible to reduce odor during combustion.

In this embodiment, the air hole 13 is connected to the fuel tank 14.
However, the same effect can be obtained even if the space 15 is communicated with the atmosphere.

Effects of the invention (1) According to the invention, the raw gas generated during extinguishing a fire can be combusted and the odor of extinguishing can be reduced.

(2) When extinguishing, the ignition heater is re-energized at the same time as the wick is lowered, and the air hole is provided on the side facing the ignition heater, so there are two pilot flames to burn the raw gas after extinguishing. , it is possible to completely burn raw gas without extinguishing the fire in the middle.

(3) If a part of the wick is cut out facing the air hole of the wick outer cylinder as in the example, the pilot flame can be left in place reliably.
