Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a petroleum-burning appliance of an upper and lower core type.

(Structure and problems of conventional example) Conventionally, a combustion cylinder is placed on a tray portion provided on the upper ends of the inner and outer cylinders, the combustion core is raised at the time of ignition, and one end of the combustion cylinder is lifted by an ignition device. The ignition heater was lit near the tip of the combustion wick. In recent years, as a combustion tube that uses a glass tube to improve heating efficiency, a glass tube having a high height and a wide infrared radiation area has been used. However, as in the past,
In the case of the configuration in which the combustion cylinder is placed on the fire tray of the outer cylinder, the center of gravity of the combustion cylinder itself is higher than the conventional one, so the appliance may tilt slightly during normal ignition operation, If the ignition operation is performed at an excessive speed, the center of gravity of the combustion cylinder exceeds the lower end position of the outer flame cylinder of the combustion cylinder and falls off.
It has a problem that it does not pass the tilt test of the equipment defined in the IS standard.

(Object of the Invention) In order to solve the above problems, the present invention aims to prevent the center of gravity of the combustion cylinder from falling below the fulcrum when the combustion cylinder is tilted so that the center of gravity of the combustion cylinder does not exceed the fulcrum to prevent falling and falling. It was done.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention interposes a combustion wick vertically movable between the annular inner cylinder and the outer cylinder of an inner core, and makes the inner flame cylinder, the outer flame cylinder and the outer cylinder concentric. The combustion cylinder arranged in
When placed on a fire plate provided on the upper end of the outer cylinder, a bent piece with both ends bent upward is provided with a recess that serves as a fulcrum for receiving the lower end of the outer cylinder when the combustion cylinder is tilted, and bends the bent piece. A part of the piece is configured to abut the side wall of the outer flame tube.

Embodiments of the Invention Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, reference numeral 1 denotes an inner flame cylinder having a large number of vent holes 1a formed on its side surface, and an upper lid 3 having a mortar-shaped flame spreading plate 2 on its upper end is capped. Reference numeral 4 denotes an external flame cylinder having a large number of vent holes 4a formed on its side surface, and a glass cylinder retainer 5 fitted and attached to a glass cylinder 6 described later is fixed to the upper end thereof. A heat-resistant transparent or translucent glass tube 6 is placed on the outer tube 7. An outer cylinder 7 on which the inner flame cylinder 1, the outer flame cylinder 4, and the glass cylinder 6 are placed is concentrically arranged and integrally assembled with cross pins 8 to form a combustion cylinder 9. Reference numeral 10 is a lead guide cylinder which is erected in a combustion tank (not shown), and is provided with a fire tray 11 on which the inner cylinder 1 is placed. 12 is a combustion tank (not shown)
The outer core of the core is mounted on the upper end of the outer flame cylinder 4. The flame tray 13 on which the outer flame cylinder 4 is placed is provided, and the flame shield plate 14 is fixed to the side wall. 15
Is a fall-prevention plate fixed to the flame shield plate 14 in the vicinity of the combustion cylinder 9, and has a notch recess 17 in a bent piece 16 with both ends bent upward.
When the combustion cylinder 9 is inclined, the lower end of the outer cylinder 7 is loosely fitted to serve as a fulcrum, and a part of the bent piece 16 is inserted into the bent piece 16 between the outer cylinder 7 and the outer flame cylinder 4. Then, a contact portion 18 for contacting the side wall of the outer flame cylinder 4 is provided (see FIG. 2). 19
Is a combustion wick vertically movably interposed between the inner and outer cylinders 10 and 12. Reference numeral 20 is an ignition device.

Since the present invention is configured as described above, as shown in FIG. 3, the combustion wick 19 is raised and the lower end of the outer cylinder 7 of the combustion cylinder 9 is raised by the ignition device 20 to be ignited by the ignition heater. At this time, the fulcrum is the bent piece 1 outside the lower end of the outer flame tube 4
6, the combustion cylinder 9 is not likely to fall off even if the instrument is inclined, and the lower end of the outer cylinder 7 remains even if the inclination test and ignition operation specified by JIS are rapidly performed. The contact portion 18 is loosely fitted in the recess 17, and the contact portion 18 is
It comes into contact with the side wall of the cylinder to prevent the combustion cylinder 9 from tilting beyond a certain level. When the appliance falls, the combustion core 19 is retracted between the core inner cylinder 10 and the core outer cylinder 12 by a core lowering device (not shown), while the lower end of the outer cylinder 7 is disengaged from the recess 17 and the combustion cylinder 9 is burned by the fire tray 11. Being separated from 13. As a result, cool air around the fire trays 11 and 13 flows into the fire trays 11 and 13 to extinguish the fire quickly, and there is also no cause for the unburned gas vaporized from the wick 19 to come into contact with the hot combustion cylinder 9 to generate odor. is there.

(Effect of the Invention) As described above, not only is the lower end of the outer cylinder 7 loosely fitted in the recess 17 of the bent piece 16 to move the fulcrum from the lower end of the outer flame cylinder 4,
Since the contact portion 18 is provided so as to contact and support the side wall of the outer flame cylinder 4, the combustion cylinder 9 falls and falls even when the center of gravity of the combustion cylinder 9 exceeds the lower end of the outer cylinder 7. However, even in the case of a particularly tall combustion cylinder 9, it is possible to deal with it by adding simple parts. In the embodiment, since the lower end of the outer cylinder 7 is received by the ignition device 20 on the right side, the fall prevention plate 15 is provided only on the left side, but it may be provided on the front and rear sides depending on the structure of the device.
