Abstract

PURPOSE:To prevent abnormal combustion by stopping combustion after a predetermined time has passed, when a level of fule in an auxiliary tank goes down lower than the predetermined level of a liquid level gauge, in a liquid fuel combustion apparatus. CONSTITUTION:When the level of fuel in an auxiliary tank 1 goes down lower than a predetermined emitting position for a photo emitting element 6, an emission A from the photo emitting element 6 is refracted by the primary prism surface (a) which is within a liquid level gauge 2 as shown by B, and is further refracted by the secondary prism surface (b) as shown by C, being sensed by a photo receiving element 7. When a detecting circuit 20 detects that a liquid level of fuel is below the predetermined level, a relay switch 16' is opened to stop combustion. With such an arrangement, abnormal combustion caused by a conventional means to stop combustion by a float switch can be prevented.

(b) Prior art In conventional liquid fuel combustion devices such as oil heaters,
A float switch is built into the main tank, which is supplied with fuel by the auxiliary tank, and when the fuel level inside the main tank drops below a predetermined level, the switch is closed or opened by the magnetic force of the magnet attached to the float to start combustion. However, according to the above configuration, since the amount of fuel stored in the main tank is small, due to variations in the operation of the float switch, air is sent along with fuel to the combustion section by the oil supply device. This has caused a problem in that the combustion flame becomes abnormally large and abnormal combustion occurs.

(1) A liquid fuel combustion device equipped with a main tank that supplies fuel to the combustion section and a removable auxiliary tank that supplies fuel into the main tank and has a translucent liquid level gauge on its side. A light emitting element and a light receiving element are disposed integrally or separately at an external position facing the liquid level gauge, and when the fuel level in the auxiliary tank falls below a predetermined position on the liquid level gauge, the liquid level is lowered. A liquid fuel combustion device characterized in that a light receiving element detects light emitted from a light emitting element by a prism action of a position gauge, and combustion is stopped after a predetermined time or immediately thereafter.
