Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to safety measures in the event of an oil combustor having a double-tube combustion tube falling over.

[Prior Art] An automatic fire extinguishing mechanism is attached to an oil combustor, and is activated to automatically extinguish the fire in the event of an earthquake or when the oil combustor falls over.

On the other hand, the oil tank of an oil combustor is prone to leak oil through the gap between the inner and outer cylinders that house the wick, and even if the automatic fire extinguishing mechanism activates and extinguishes the fire, the combustion cylinder is located near the top of the wick storage cylinder. During this process, there was a problem in which unburned gas came into contact with the high-temperature combustion tube and ignited, starting combustion again.

As a countermeasure like this, the combustion tube is mounted on the inner and outer core cylinders, and the structure is such that the combustion tube pops out when it falls over.
There is a proposal to support and hold the protruding combustion cylinder from the outside with a guard. (Refer to Utility Model Application No. 59-148504) [Problem to be solved by the invention] By the way, as mentioned above, the problem of re-ignition when the oil combustor falls over has been almost technically solved, but If the combustion tube is only slightly bent, it will instantly pop out a lot when it falls over, and if the combustion tube is supported by a guard or the like, it may become deformed or damaged when the combustion tube pops out and hits the guard.
Even if the major problem of re-ignition and fire caused by a fall was resolved, a new problem would arise in which the combustion tube would break and become unusable. In particular, recently there have been many cases in which fragile glass is used as the material for combustion tubes, and new countermeasures have been desired.

[Means to solve problems]

This idea improves the fire extinguishing performance in the event of a fall by modifying the frame structure of the oil combustor, while also making the combustion cylinder less likely to break.The core and outer cylinders 2 and the automatic fire extinguishing mechanism 11 are located above the oil tank 9. Core inner and outer cylinder 2
A lower frame body 1 is provided to cover the automatic fire extinguishing mechanism 11, and the lower frame body 1 has an opening 3 in the upper part facing the core inner and outer cylinders 2, and a combustion tube 4 with an open upper end is provided in the opening 3 of the lower frame body 1. The core is mounted on the upper end of the inner and outer cylinders 2,
In a petroleum fuel device that has an upper frame 5 continuous from the lower frame 1 above the combustion tube 4, the combustion tube is attached to the periphery of the opening 3 of the lower frame 1 that is below the combustion tube 4 when it falls over. A fall assist guide 6 is provided on the lower side of the combustion tube 4, and a fall support guide 7 is provided on the upper frame 5 so that the combustion tube 4 can be seen from the upper end opening into the inside of the combustion tube 4. The moved combustion tube 4 has its upper end opening locked with the tipping support guide 7 and its lower side with the tipping assist guide 6.

In addition, in the case of an oil combustor, such as the convection type oil combustor shown in the figure, where the stand is circular and the direction of overturning is not determined, the overturning auxiliary guide 6, which is visible from the lower side of the combustion tube 4, is An overturning guide 7, which is provided surrounding the periphery of the opening 3 and looks inside the combustion tube 4, is located approximately at the center of the upper end opening of the combustion tube 4, so as to cope with overturning in multiple directions.

[Effect]

In this invention having the configuration described above, when the oil combustor falls over, the fire extinguishing mechanism 11 is activated to forcibly extinguish the oil combustor.

In addition, since there is an overturn assisting guide 6 visible at the lower side of the combustion tube 4, and an overturn support guide 7 is provided at the top opening of the combustion tube 4, the combustion tube 4 is When the core protrudes from the upper end of the inner and outer cylinders 2, even if there is a gap between the upper end opening and the tipping guide 7, the inertia force generated when it pops out causes the tipping guide 7 to close.
On the other hand, the lower end of the combustion tube 4 is separated from the upper end of the core and inner and outer cylinders 2, and the lower side of the combustion tube 4 is locked and held by the falling assist guide 6 outside the opening 3. be. The part where the combustion tube 4 is held is not the central part of the combustion tube, which has poor strength, but the upper opening edge or the lower outer peripheral edge, which is advantageous in terms of strength, and can be held securely without deformation. It is possible. In addition, when the cylinder falls, the central part of the cylinder does not come into contact with parts of the oil combustor, such as the guard or reflector, and is caught in the air, eliminating the risk of deformation or damage.

Furthermore, regarding the fall assist guide 6 and the fall support guide 7, the fall support guide 6 is provided to surround the periphery of the opening 3, and the fall support guide 7 is located approximately in the center of the upper end opening of the combustion cylinder 4, so that oil The combustor can be used even if the combustor falls over in any direction, and the positional relationship between the combustion cylinder, the core inner and outer cylinders 2, and the upper and lower frames 1 and 5 remains constant when the combustor falls over.

In addition, the fall assist guide 6 is not the core inner and outer cylinders 2,
Since it is attached to the periphery of the opening 3 of the lower frame body 1 that covers the core inner and outer cylinders 2, the upper ends of the core inner and outer cylinders 2 and the combustion tube 4 will be exposed when the core falls.
Since a gap is formed between the core and the lower end, even if a large amount of unburned gas is released from the gap between the inner and outer cylinders after falling and extinguishing the fire, the unburned gas will escape upward through the gap and be sucked into the combustion tube 4. Even if an oil combustor extinguishes due to a fall, there is no longer any fear that it will start burning again due to ignition.

When installed, the heat shield plate 8 becomes a part of the upper frame 5, and an appropriate distance can be formed between it and the combustion tube 4. Therefore, the heat shield plate 8 becomes a part of the upper frame 5, and an appropriate distance can be formed between the overturn guide 7 and the overturn auxiliary guide 6. The combustion tube 4 can be locked to the cylinder.

〔effect〕

As described above, this invention prevents the combustion cylinder 4 that protrudes from the upper part of the core inner and outer cylinders 2 from falling and being deformed or damaged when the oil combustor falls down, and the fall assist guide 6
Since the oil combustor is prevented from falling by the guide 7, the durability of the oil combustor is improved.

In addition, since the tipping assist guide 6 is provided surrounding the periphery of the opening 3 of the lower frame 1, and the tipping support guide 7 is made to look into the center of the interior from the upper end opening of the combustion tube, the oil combustor tipping direction is different. The combustion cylinder 4 is reliably received, the positional relationship between the inner and outer core cylinders 2 and the combustion cylinder 4 is constant, and the automatic fire extinguishing device eliminates variations in fall extinguishing performance and stabilizes the fire extinguishing performance.
