閉本している。(B) Prior art As a conventional oil combustion device of this kind, for example, as disclosed in Japanese Patent Publication No. 63-45003, a burner case is provided around the outer periphery of a vaporizing cylinder heated by a heater.
The structure is such that secondary combustion air is sent into the burner case, and a through hole is provided in the peripheral wall of the burner case, and the secondary combustion air guided from the air passage member penetrated through the through hole. There is known a system in which, after premixing the vaporized gas of petroleum fuel in the vaporization cylinder, this mixed gas is ejected from a burner head at the top of the vaporization cylinder and combusted. Generally, in order to prevent combustion secondary air from leaking from the through-hole, a seal made of non-combustible fiber such as glass fiber or ceramic fiber is used to fill the gap between the edge of the through-hole and the air passage member. The book is closed due to parts.

出してシール部材に染み込んでしまう。(8) Problems to be Solved by the Invention By the way, the above-mentioned sealing member made of non-combustible fibers does not burn by itself, but it has a property that petroleum fuel easily soaks into it. If the circuit's microcomputer goes out of control due to noise or other causes and continues to supply fuel without issuing an energization signal to the heater that heats the carburetor, unvaporized petroleum fuel will accumulate in the carburetor. The petroleum fuel overflows from the vaporization cylinder and enters the air passage member, flows out from the joint of the air passage member, and soaks into the sealing member.

内部配線等に引火して火災を起こす等の心配があった。When the microcomputer returns to normal and outputs a normal combustion start signal, the heater is energized and the vaporization tube is heated to a high temperature, and the petroleum fuel that has soaked into the sealing member receives the heat from the vaporization tube. There was concern that it would evaporate and ignite, which could ignite internal wiring and cause a fire.

The aim is to improve safety in this way.
