Description

[Detailed description of the invention] (a) Industrial application field The present invention provides combustion from a fuel storage section, a fuel supply section formed on the fuel storage section, and a combustion section placed on the fuel supply section. The present invention relates to an oil combustor comprising a container body, a decorative frame arranged to cover the periphery of the fuel supply section, and an operation nameplate made of synthetic resin attached to an opening provided on the peripheral side of the decorative frame.

(b) Prior Art A conventional oil combustor of this type will be explained below based on FIGS. 1 and 2. Reference numeral 1 denotes a core frame as a fuel supply unit installed on a fuel tank 1 as a fuel storage unit that is mounted and fixed on a mounting table 2 via support legs 3, 3, and a lower end is provided in the core frame 4. A vertically movable lamp wick (not shown) is provided which is immersed in the fuel in the fuel tank 1. 5 is a combustion tube as a combustion section placed on the core frame 4;
The combustion tube 5, core frame 4, fuel tank 1, etc. constitute a combustor main body A.

Reference numeral 6 denotes a rotary knob attached to the tip of the wick vertical shaft 7 for vertically moving the lamp wick disposed in the wick frame 4, 8 a fuel filler port provided on the upper surface of the fuel tank 1, and 9 a fuel tank. This is an oil gauge that displays the fuel level within 1.

Reference numeral 10 denotes a decorative frame which is mounted on the fuel tank 1 at the outer periphery of the core frame 4 and has an opening 10' in the front part of the cylindrical circumferential side.
A partition plate 11 having a through hole (not shown) for the combustion tube 5 in the center is fitted to the upper end, and the lower end is fixed to the outer periphery of the upper surface of the partition plate 11. Moreover, a protective guard 13 having an inverted dish-shaped top plate 12 attached thereto is disposed at the upper end.

Reference numeral 14 denotes an operation nameplate which is molded from synthetic resin such as ABS and has a horizontal rectangular shape when viewed from the front and has a circumferential side surface 15 on its periphery. 6, an ignition knob 16 for operating an ignition device (not shown), and a fire extinguishing knob 17 for operating a fire extinguishing device (not shown).
The perforation holes 18 and 1 are formed so as to protrude outward.
9 and 20 have been opened. Further, the peripheral side portion 1
At appropriate positions on the inner edges of the upper surface part 15' and the lower surface part 15a of 5, there are hooks to be hooked to the tips of bent pieces 21 formed by bending the periphery of the opening 10' inward, one on each left and right. An appropriate number of protruding pieces 22, 22 having protrusions 22', 22' formed thereon are integrally formed, and the inner end surface of the circumferential side part 15 of the operation nameplate 14 is brought into contact with the outer surface of the peripheral edge of the opening 10', and the protruding pieces 22,2
Hooking protrusions 22', 22' formed at 2 are hooked onto the tip of the bent piece 21, and the operation nameplate 14 is fixed to the decorative frame 10. Further, the operation nameplate 14 is formed in an arcuate shape substantially concentric with the outer surface of the decorative frame 10 in plan view, so that it can be easily attached to the decorative frame 10.

In the conventional oil combustor mentioned above, the radiant heat released from the combustion tube 5 during combustion is radiated to the operation nameplate 14 for a long time even though it is small, and the area around the operation nameplate 14 is affected. As the ambient temperature rises, the operating name plate 14, which is made of synthetic resin, may become thermally deformed or catch fire.

(c) Purpose of the invention The present invention has been improved in view of the above-mentioned drawbacks of the conventional technology, and its purpose is to prevent thermal deformation or ignition of the operating nameplate, which occurred in the past, through a simple structure.

(d) Structure of the device A knob for combustion control extending from the fuel supply part is made to protrude outward from a hole formed in the operation nameplate, and a hole is made at the contact area between the lower edge of the operation nameplate and the decorative frame. is formed.

(e) Embodiment An embodiment of the present invention will be described below in detail with reference to FIG. 3, and elements that are the same as those of the conventional device will be given the same numbers and their explanation will be omitted. Reference numeral 23 denotes a notch formed in the lower surface portion 15a of the peripheral side surface portion 15 of the operation name plate 14 which can be molded from synthetic resin;
are provided between the protruding pieces 22 formed on both the left and right ends of the lower surface portion 15a, and when the operation name plate 14 is attached to the decorative frame 10, an opening B is formed through the cutout portion 23 to allow outside air to flow in. be done.

When the combustor main body A is combusted, the outside air as part of the combustion air flows through the opening B through the arrow A.
The air flows into the decorative frame 10 as shown in (B), and the air is sucked into the combustion tube 5 and contributes to combustion. Therefore,
The air shown by arrow B flowing in through the opening B can prevent the temperature of the operating nameplate 14 and its surroundings from rising, and the operating nameplate 14 may be deformed or ignited by the radiant heat from the combustion tube 5, unlike in the conventional case. You can prevent them from doing so.

(F) Effects of the invention Since the invention is constructed as described above, it has the following effects.

Since holes are formed in the parts where the operation nameplate and decorative frame touch each other, the air flowing in through the holes during combustion can prevent the temperature of the operation nameplate and its surroundings from rising, improving productivity and design. The operation plate made of synthetic resin can be prevented from deformation and ignition, and the knob located inward from the operation plate can also be prevented from heating due to the air flow flowing in from the opening B. is,
Deterioration due to heat is suppressed and operability is improved. In addition, maintenance and inspection of the fuel supply section can be performed through the opening of the decorative frame by removing only the operation nameplate from the decorative frame without removing the entire decorative frame surrounding the fuel supply section.
