Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a drop oil combustor equipped with a cartridge tank.

(b) Prior Art Conventionally, in the fuel tank of a drop-type oil combustor equipped with a cartridge tank, the side wall of the saucer in which the cap valve of the cartridge tank is interposed is opposite to the oil sump part with the lamp wick interposed therein. As shown in Japanese Utility Model Publication No. 54-6901, a fuel filler opening with a fuel filler hole provided therein is known.

However, in this type of conventional fuel tank, the fuel filler port drilled into the side wall of the saucer is located at a position opposite to the oil sump side, so if the device falls over with the saucer facing downward, Most of the fuel accumulated on the oil sump side leaked from the saucer to the outside through the fuel filler port, posing a risk of contamination and flames due to fuel leakage.

(c) Purpose of the invention The present invention was made in view of the problems of the prior art described above, and includes providing a fuel filler port on the peripheral wall of the communication portion of the saucer and providing a baffle plate on the outside of the fuel filler port. The purpose of this is to prevent fuel from flowing out when the device falls over, prevent dangers such as flames, and make the fuel tank more compact.

(d) Structure The present invention provides an oil reservoir section 4, an oil receiver section 5, and a communication section 7 that connects these in the lower part of the tank 3 so as to protrude downward. A cap insertion port 13 that penetrates the fuel supply section 15 of the cartridge tank 10 is provided, and the cap insertion port 13
A bottomed cylindrical saucer 6 that surrounds the mouthpiece insertion port 13 and has its lower part exposed to the inside of the oil pan 5 is provided between the oil pan 5 and the oil pan 5 . It has a structure in which a fuel filler port 8 is provided and a baffle plate 9 is provided on the outside of the fuel filler port 8.

(E) Embodiment An embodiment of the present invention will be explained based on the drawings. 2 is a lower plate formed by drawing and forming a metal plate, and has an oil reservoir 4 on one side and a cartridge type oil tank 1 on the other side.
An oil receiver 5 that receives fuel dripped from the
A communication groove 7 is formed between the oil receiving portion 5 and the oil reservoir portion 4 as a communicating portion that connects them, each projecting downward. Further, a wick guide tube 12 is press-fitted onto the outer periphery of the tube 11 that stands up in the oil sump 4 and guides the vertical movement of a wick (not shown) whose lower end is immersed in the fuel in the oil sump 4. It has been done.

Reference numeral 1 denotes an upper plate which is fixed to the lower plate 2 by seaming or the like and constitutes the fuel tank 3 together with the lower plate 2, and has a tapered shape that widens at the top and allows the cap valve 15 of the fuel tank 10 to pass through it at a position opposite to the oil receiving part 5. A mouthpiece insertion port 13 is bored therein, and an oil reservoir bulging portion 14 is provided opposite the oil reservoir portion 4 .

Reference numeral 6 denotes a bottomed cylindrical saucer formed of a metal plate or resin into which the cap valve 15 of the fuel tank 10 can be inserted and removed, and the flange portion 16 at the top of the saucer 6 is
is fixed to the periphery of the base insertion opening 13 on the lower surface of the upper plate 1 by spot welding or the like.

17 is the cap valve 1 when the fuel tank 10 is inserted or removed.
5, and is provided at the center of the lower surface of the saucer 6.

Reference numeral 8 denotes an oil filler port 8 located on the side of the oil reservoir 4 and the communication groove 7 and bored in the side wall of the saucer 6. The oil filler port 8 is formed in a horizontal rectangular shape and is constantly immersed below the oil surface. There is.

9 is spaced apart from the oil filler port 8 and is connected to the oil filler port 8.
It is a baffle plate provided to cover the outside of the tank, and is made of a metal plate, resin, etc., and its both ends are located on both sides of the fuel filler port 8 and are fixed to the outer surface of the side wall of the saucer 6 by spot welding or the like. .

By the way, when the saucer 6 is molded from synthetic resin, it is possible and desirable that the baffle plate 9 also be integrally molded from resin.

Therefore, the cap valve 15 of the fuel tank 10
When inserted into the saucer 6 through the mouthpiece insertion port 13, the kip valve 15 is opened by the rod 17, and the fuel in the fuel tank 10 is dripped into the saucer 6. The fuel supplied into the saucer 6 flows out from the fuel filler port 8, a predetermined amount is stored in the oil reservoir 4, and is sucked up into the lamp wick and used for combustion.

Now, the equipment is overturned and the saucer 6 side is downward and the oil sump 4
When the side is located upward, the fuel in the oil reservoir 4 flows toward the saucer 6 side and tries to flow into the saucer 6 from the fuel filler port 8, but the baffle plate 9 provided on the outside of the fuel filler port 8 prevents the fuel from flowing. As shown in FIG. 2, the oil is diverted in the direction of the arrow, that is, to the side of the oil receiving tray 6, and is stored in the space inside the fuel tank 3 on the side of the oil receiving portion 5 without almost flowing into the oil receiving tray 6. .

Furthermore, since the fuel filler port 8 is provided on the peripheral wall of the saucer 6 on the communication groove 7 side, if the vehicle rolls over as described above, the fuel filler port 8 will be open at the top of the saucer 6. In the event of a rollover, the baffle plate 9 prevents fuel from flowing into the saucer 6, and the fuel can be stored in the space around the saucer 6 at a level lower than that of the fuel filler port 8. Also, it does not leak out through the cap insertion port 13.

Furthermore, by providing the fuel filler port 8 on the peripheral wall of the saucer 6 on the side of the communication groove 7, the fuel filler port 8 opens at the top of the saucer 6 in the event of a rollover as described above. The oil reservoir space around the saucer 6 can be set larger, and the fuel tank 3 can be made smaller accordingly.

(F) Effect As described above, according to the present invention, an oil reservoir section, an oil receiver section, and a communication section connecting these are provided in the lower part of the tank so as to protrude from the bottom, and the upper wall of the tank facing the oil receiver section is provided with an oil reservoir section, an oil receiver section, and a communication section connecting these sections. A cap insertion port is provided that penetrates the fuel supply section of the cartridge tank, and a bottomed cylindrical tube that surrounds the cap insertion port and whose lower part faces into the oil receiver is provided between the cap insertion port and the oil receiver. A saucer is provided, and a fuel filler port is provided on the peripheral wall of the saucer on the communication side, and a baffle plate is provided on the outside of the filler port, so if the instrument falls over and the saucer side is located downward, the baffle plate By positioning the fuel filler port covered by the oil filler at the top of the saucer, the baffle plate prevents fuel from flowing into the saucer through the filler port, while allowing the fuel to be diverted into the tank around the outer periphery of the saucer. This prevents fuel from flowing out from the nozzle insertion port in the event of a fall, and prevents dangers such as flames caused by spilled fuel igniting.It also prevents the oil from flowing out from the oil sump around the saucer without increasing the size of the tank. Since the space can be set large, the fuel tank can be made more compact. Further, since the baffle plate allows fuel flowing toward the fuel filler port to be detoured to the side, backflow of fuel into the saucer can be suppressed, and fuel leakage can be more reliably prevented. Furthermore, since the baffle plate may be small enough to cover the fuel filler port, the configuration can be simplified and the cost will not increase significantly.
