石油フアンヒーター。[Claims for Utility Model Registration] (1) In an electric stove with a tipping switch that turns off the heater power if it tips or falls over,
A light-reflecting surface, and a light-emitting element and a light-receiving element are arranged toward the light-reflecting surface at a position slightly away from the light-reflecting surface, so that when the electric stove tilts or falls over,
Detecting a tilted or overturned state of the electric stove, comprising means for turning off or on the light receiving element by moving the direction or position of the light reflecting surface,
An electric stove characterized in that this detection signal drives a relay or the like to turn off the heater power. (2) In a kerosene fan heater with an anti-seismic automatic fire extinguishing device that activates a solenoid valve to cut off the fuel supply and extinguish the fire when a vibration is detected, place a box that can be seen through, and place a box in the center of the ceiling of the box. A light-emitting element is placed in the bottom, an optical fiber is optically coupled to the light-emitting element, and the light-emitting element is suspended, and a weight is placed at the end of the light-emitting element so that the light from the light-emitting element that has passed through the optical fiber is emitted from the center of the bottom surface. A light-receiving element is placed facing upward on the bottom of the box located directly below the light emitting part of the weight, and when the box is subjected to vibration, the weight shakes and the light emitting element passes through the optical fiber to the bottom of the weight. The light emitted from the center intermittently reaches the light receiving element, and is equipped with a vibration detector that extracts the electric signal of the light receiving element that turns on and off as a vibration detection signal, and detects vibrations when the oil fan heater is subjected to vibrations. An oil fan heater with an anti-seismic automatic fire extinguishing device, characterized in that a detection signal drives an electromagnetic valve to cut off fuel supply. (3) In the vibration detector according to claim 2, a position indicating line indicating the position of the outer periphery of the weight when hanging is written on the bottom of the box located directly below the weight of the vibration detector, By checking the overlap between the outer circumference of the weight and the position indicator line written on the bottom of the box, the outer circumference of the weight can be checked by providing a means to visually confirm the horizontal position. The oil fan heater is characterized in that it is possible to visually confirm that the position is shifted from the position indicating line shown on the bottom of the box.
