Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is a petroleum wick that is divided into a plurality of parts and is installed in a wick storage part so that it can be raised and lowered freely, so that each wick can burn independently. Related to liquid fuel combustion devices such as stoves.

(Technical Technique) In a well-known wick type liquid fuel combustion device, when adjusting its calorific value, the degree of combustion is adjusted by slightly moving the wick up and down. However, such adjustments cannot significantly change the combustion conditions. This is because if the wick is moved up and down significantly, incomplete combustion tends to occur, resulting in the generation of standing flames and odors. For this reason, as shown in FIG. 7, a liquid fuel combustion device is known from Japanese Utility Model Publication No. 18648/1983, in which a plurality of combustion wicks 1 and 2 are provided in a wick storage portion 3 so as to be movable up and down. In such a device, when some of the wicks are burned, vaporized gas is generated from the remaining wicks due to radiant heat, causing odor.

As a means to solve these problems, Japanese Patent Publication No. 57-31043 discloses a method in which a guide plate with an open top is installed horizontally on the outside of the fire pan, and is locked to the inner cylinder part to shield the core storage part. A liquid fuel combustion device has been proposed in which a shielding plate is slidably provided on the guide plate.

(Problem to be solved by the invention) In the above-mentioned conventional technology, even when the core storage part is shielded by the shielding plate, a part of the lead storage part and the outside communicate with each other through the combustion hole in the inner cylinder part. Due to this condition, there were problems such as incomplete combustion even after the fire had been extinguished, and vaporized gas leaking outside and creating an odor.

This idea was developed in a liquid fuel combustion device in which the combustion wick is divided into multiple parts and the wicks are placed in a wick storage part so as to be able to move up and down. The purpose is to provide a closing function and to prevent leakage of vaporized gas from around this closing means and incomplete combustion.

[Structure of the invention] (Means for solving the problem) In this invention, a core divided into a plurality of parts is disposed in a core storage section formed between a burner basket and a core guide cylinder so as to be able to move up and down, and the burner basket can be moved up and down. A storage case is provided by integrating an upper case in which a fire pan is formed with a lower case provided on the outside of the upper part of the housing, and a horizontal surface is formed at a portion of the core guide tube that faces the lower case, and the core is stored in the storage case.
