Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vaporizing pot type burner used in a vaporizing pot type oil combustor.

BACKGROUND TECHNOLOGY A conventional vaporizing pot burner is as shown in FIG. A lower burner 2 is welded to the peripheral wall of the burner 1. 3 is a heater, and the heat generating part 3A of this heater 3 is placed at an appropriate distance A to the flat surface 2A of the lower burner 2.
and the other is attached to the side wall of the burner 1 via a packing (not shown). Reference numeral 4 denotes a combustion aid provided within the burner 1. A joint pipe 5 is provided on the side wall of the burner 1 and forms a fuel supply port.

Problems to be Solved by the Invention According to the above configuration, if fuel is supplied into the burner 1 more than necessary due to some kind of malfunction and flows into the lower burner 2 in excess of the appropriate amount, the flat surface 2A of the lower burner 2 is There are problems such as blocking radiant heat from the covered heater 3, reducing heat conduction on the flat surface 2A and inhibiting good combustion, and even worse, radiant heat from the side of the burner 1 to which the heater 3 is attached.
There were problems such as leakage through the bottom surface of the gasket and leaking out of the burner 1.

Means for Solving the Problems The present invention was made to eliminate the above-mentioned drawbacks. Specifically, the bottom of the burner, which has a flat surface, is welded to the bottom of the burner. In a vaporizing pot type burner in which the heat generating part of the heater is located on the lower flat surface at an appropriate distance from it, the heat generating part of the heater is parallel to the flat surface below the burner, and A recess along the inner periphery of the burner is formed on the outside of the flat surface, and the peripheral edge below the burner is raised up to near the height of the flat surface and fixed to the outer periphery of the bottom of the burner. be.

Effect By configuring as described above, it is possible to not only prevent a slight oversupply of fuel into the burner, but also to store and absorb the fuel that reaches the heater mounting part in the recess, preventing fuel from flowing out. As with a flat surface, the radiant heat from the heater can be conducted well, and safety can be improved without reducing ignition performance.

Example An embodiment of the present invention will be described below with reference to the drawings.

The configuration of the embodiment is as shown in FIG. In the figure, the numbered parts other than the numbered parts 2, 2A, and 2B indicate parts common to the same numbered parts in FIG. 2, and the explanation thereof will be omitted.

2 is under the burner, and there is a flat surface 2A corresponding to the heat generating part 3A of the heater 3 and having an appropriate distance A and an area necessary for proper vaporization; Forming a recess 2B having a volume comparable to the volume inside the burner 1 between the lower mounting sides,
And raise the periphery to near the height of flat surface 2A, and
It is fixed by welding to the outer circumferential wall of the case 1.

Next, the operation of this embodiment having the above configuration will be explained.

In the unlikely event that there is an excessive supply of fuel in the burner 1, or even if the fuel is injected to the heater 3 mounting part, the recess 2B can store and absorb this amount of fuel. It prevents the fuel from flowing out, and also improves the heat conduction of the radiant heat from the heater 3, just like a conventional flat surface.Furthermore, the fuel accumulated in the recess 2B receives the radiant heat from the heater 3, and gradually becomes airy due to heat conduction. It burns and disappears. In this way, safety is improved without reducing ignition performance.

Effects of the invention As described above, according to the invention, by providing a concave portion along the inner circumference of the burner below the burner, even if fuel is supplied into the burner slightly exceeding the appropriate value, the heater can be fixed. Even if a large amount of fuel is supplied to the vicinity of the recess, the fuel can be stored in the recess and the fuel can be prevented from flowing out.
It has the effect of improving safety without reducing ignition performance.

In addition, even if fuel accumulates in the recess under the burner, the peripheral edge under the burner is raised up to its flat surface and fixed to the outer peripheral wall of the burner, so even in the unlikely event of an accident, it is possible to secure both sides. This has the effect of preventing fuel from flowing out from the surface.
