<p>An oil heating equipment such as a kerosene stove having a wick adapted to be moved vertically between a raised position where the fire is set thereon and a lowered position where the fire is extinguished. Means are provided for limiting the range of adjustment of the wick height to prevent the wick from coming down below the range optimum for the burning. The equipment has two modes of extinction: namely, an ordinary extinction mode in which the fire can be extinguished gradually to leave no unfavourable smell of unburnt fuel vapor, and an emergency extinction mode in which the fire can be extinguished instantaneously to ensure the safety. The equipment has a limiting mechanism for limiting the manual rotation of the wick driving shaft in the wick lowering direction to a predetermined range, a limit dismissing mechanism for dismissing the limitation imposed by the limiting mechanism, thereby allowing the wick driving shaft to rotate in the wick lowering direction beyond the range, and a stop mechanism which is adapted to stop, when the wick driving shaft is manually rotated after the dismissal of the limit of rotation range, the wick driving shaft at a rotational position aback from the rotational position to which the wick driving shaft is rotated when the wick is lowered quickly by the force of the spring means after the locking means is made inoperative by the operation of the anti-earthquake emergency extinction means. With this arrangement, it is possible to obtain the above-mentioned two extinction modes, while limiting the height adjustment of the wick to the range for maintaining good state of burning.</p> |
