Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to an oil supply device for an oil heater that supplies oil (kerosene) for fuel to a fixed tank of the oil heater.

(Prior Art) Generally, in an oil heater such as an oil stove, a fixed tank is provided in the body of the oil heater, and the oil in the fixed tank is sequentially introduced into a combustion section and burned. And the cartridge tank is inserted and removed freely in the body,
Oil is sequentially supplied from this cartridge tank to the fixed tank, and when the cartridge tank becomes empty, the cartridge tank is taken out of the body, and oil is replenished to the inside using a manual pump or the like. The cartridge tank is again inserted into the body to supply oil to the fixed tank.

(Problems to be solved by the invention) However, replenishing oil to the cartridge tank each time in this way is troublesome and troublesome, and the hand and its surroundings may be soiled with oil during the replenishment work. Many.

Therefore, in place of the cartridge tank, an oil-sealed disposable oil pack made of, for example, paper or plastic is configured, and a plurality of such oil packs are prepared in advance,
Insert one of them into the container and supply the oil from the lower end to the air in the fixed tank by replacing the air from the lower end, and replace it with a new oil pack when the oil becomes empty. The means to do is possible.

In such a case, provide a storage cylinder that communicates with the fixed tank,
The oil pack is housed in this storage cylinder to supply oil to the fixed tank.If there is a hole in the oil pack for some reason, air will flow into the oil pack through the hole. The oil in the oil pack then flows into the fixed tank indefinitely, which causes the oil level in the fixed tank to rise significantly above the specified level and overflow from the fixed tank, causing this oil to catch fire and cause an unexpected fire. May invite.

This invention was made with this point in mind, and its purpose is to prevent excess oil from leaking to the fixed tank even if there are holes in the oil pack. The object is to provide an oil heater oil supply device.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve such an object, the present invention includes a fixed tank provided in an oil heater, and a storage cylinder provided on the fixed tank. , A refueling portion protruding from the bottom surface of the storage cylinder into the fixed tank, a valve hole formed in the bottom surface of the refueling portion, a breaking needle provided inside the refueling portion, and an upper end of the storage cylinder. An openable and closable lid that hermetically seals the opening, a valve body that interlocks with the opening and closing operation of the lid to close the valve hole when the lid is opened, and opens when closed, and a nozzle at the lower end that seals oil. And a disposable oil pack in which the opening of the nozzle is sealed with a thin sheet, the oil pack is stored in the storage cylinder, and the nozzle is inserted into the oil supply section to break the thin sheet. Break it with a needle, close the lid, and And to sealing, in which so as to open the valve hole in cooperation with the valve body in operation of the lid.

(Operation) In the oil supply device having such a configuration, the oil pack is stored in the storage cylinder, the nozzle is inserted into the oil supply section, the thin sheet is broken by the breaking needle, and the lid is closed to close the storage cylinder. When airtightly sealed, the valve body moves in conjunction with the lid body, the valve hole of the oil supply section is opened, and the oil in the oil pack flows out of the nozzle through the valve hole into the fixed tank. Oil is supplied while maintaining a constant level inside.

If there is a hole in the oil pack under such a condition, the air in the storage cylinder will flow into the oil pack through the hole, and therefore the oil in the oil pack will sequentially flow out through the nozzle. . However, since the inside of the storage cylinder is in an airtight sealed state, the oil that has flowed out flows from the oil supply unit into the storage cylinder and is stored in the storage cylinder.

When the lid of the storage cylinder is opened in this state, the valve element moves in conjunction with this, and this movement closes the valve hole of the refueling unit, so the storage cylinder is opened and atmospheric pressure is released inside the storage cylinder. Even if it works, the oil stored in the storage cylinder remains in the storage cylinder as it is,
Therefore, the oil does not excessively flow into the fixed tank and overflow from the fixed tank.

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

In the figure, reference numeral 1 is a fixed tank provided inside the body of an oil heater, and an opening 2 is formed in a part of the upper surface of the fixed tank 1, and a filter cylinder 3 is formed on the inner surface of the fixed tank 1 so as to face the opening 2. Is attached, and a plurality of flow holes 4 are provided on the peripheral surface of the filter cylinder 3.
... has been drilled.

A storage cylinder 5 is attached to the upper surface of the fixed tank 1, a guide cylinder 6 protruding into the fixed tank 1 through the opening 2 is attached to the bottom surface of the storage cylinder 5, and a valve cap 7 is provided below the guide cylinder 6. Airtightly screwed onto this valve cap 7
A valve hole 8 is formed in the central portion of the bottom surface of the above, and such a guide cylinder 6 and valve cap 7 constitute an oil supply portion 9.

A bottomed cylindrical pack receiver 12 is vertically movably inserted into the oil supply unit 9, and the pack receiver 12 is elastically biased upward by a spring 13. A valve rod 14 is inserted and fixed to the center of the bottom surface of the pack receiver 12, and a plurality of outflow holes 15 are formed in the peripheral portion of the bottom surface. The valve rod 14 integrally has a valve body 16 at an end of a portion projecting downward of the pack receiver 12, and the valve body 16 is disposed below the oil supply section 9 through a valve hole 8 of the oil supply section 9. The urging force of the spring 13 causes the valve hole 8
Elastically abuts against the valve hole 8 to seal the valve hole 8, and the upper end portion of the valve rod 14 protruding inward of the pack receiver 12 has a breaking needle 17
Is configured as.

A lid 21 is rotatably pivotally attached to an opening at the upper end of the storage cylinder 5 via a hinge pin 20. The lid 21 has an engaging hook 22 at an edge opposite to the hinge pin 20.
Is rotatably attached via a support pin 23.
The locking hook 22 integrally has a locking claw 26 at one end and a knob 27 at the other end, and a locking pin 28 that can be engaged with and disengaged from the locking claw 26 is provided on the outer side of the storage cylinder 5. Has been. Also, on the inner surface of the lid body 21, the pack holder 2 is provided at the substantially central portion
9 and a packing 30 is attached to the peripheral portion.

31 is a disposable type oil pack, and this oil pack 31 is made of paper or plastic, and oil (kerosene) is sealed inside. A nozzle 32 is attached to the lower end of the oil pack 31, and a thin sheet 33 is stretched at the opening at the tip of the nozzle 32, and the thin sheet 33 prevents oil from flowing out (FIG. 3). Note that 34.35 is a pack guide provided inside the storage cylinder 5.

Next, the operation will be described.

When supplying oil into the fixed tank 1, the oil pack 31 is stored in the storage cylinder 5, and the nozzle 32 is inserted into the pack receiver 12. Then, the lid 21 is closed, and the locking hook 22
Hook the locking claw 26 of No. 2 onto the locking pin 28 and pack 3
0 is pressed against the opening edge at the upper end of the storage cylinder 5 to seal the storage cylinder 5. In accordance with this operation, the oil pack 31 in the storage cylinder 5 is pressed downward by the pack presser 29, and the thin sheet 33 of the nozzle 32 is broken by the pressing force via the breaking needle 17, and the oil pack 31 is spring-loaded. It moves downward integrally with the pack receiver 12 against the urging force of the valve 13, and this movement causes the valve element 16 to separate from the valve hole 8 to open the valve hole 8. When the thin sheet 33 is broken, the oil in the oil pack 31 sequentially flows out through the nozzle 32 by replacing the air around it, and further this oil flows out from the outflow holes 15 through the valve hole 8 into the fixed tank 1. (Fig. 1).

In this way, the oil flows out and the oil level in the fixed tank 1 is set to level A. When the oil level reaches level B in the oil supply section 9, the inflow of air into the oil pack 31 is disabled. The oil flow from the oil pack 31 stops. Then, when the oil in the fixed tank 1 is used for combustion and the level A is lowered, the level B is also lowered accordingly, and the air is flown into the oil pack 31 through the nozzles 32 from the inflow holes 15 ...
Oil corresponding to the amount of this air flows from the nozzle 32 into the inflow hole 1
5 to flow into the refueling section 9, and this oil further flows into the fixed tank 1 through the valve hole 8, whereby the oil levels in the fixed tank 1 and the refueling section 9 return to the A and B levels, respectively. Then, by repeating this, the oil pack 3
The oil in 1 is sequentially supplied into the fixed tank 1.

When the inside of the oil pack 31 becomes empty, the lid 21 is opened and the oil pack 31 is taken out from the storage cylinder 5 and replaced with another oil pack 31 prepared in advance. Then, the empty oil pack 31 taken out from the storage cylinder 5 is discarded. According to such handling, unlike the case of the conventional cartridge tank, it is possible to handle the cartridge tank conveniently without the trouble of replenishing the cartridge tank with oil and soiling hands and surroundings with oil. .

By the way, when there is a hole in the oil pack 31 for some reason while the oil pack 31 is stored in the storage cylinder 5 and used, the air in the storage cylinder 5 is put into the oil pack 31 through the hole. , And therefore the oil in the oil pack 31 sequentially flows out through the nozzle 32 and the outflow holes 15. However, since the inside of the storage cylinder 5 is in an airtight closed state, the oil that has flowed out rises into the storage cylinder 5 through the gap between the outer circumference of the pack receiver 12 and the inner circumference of the oil supply section 9 and reaches a certain level. It is kept and stored in the storage cylinder 5.

Under this condition, when the lid 21 of the storage cylinder 5 is opened (FIG. 2), the pressure on the oil pack 31 is released accordingly, so that the oil pack 31 is biased by the spring 13. 31 and the pack receiver 12 are integrally lifted, and the valve body 16 collides with the valve hole 8 by the ascending operation and the valve hole 8 is sealed. Therefore, the opening of the upper end of the storage cylinder 5 is opened for storage. Even if the atmospheric pressure acts on the cylinder 5, the oil stored in the storage cylinder 5 remains in the storage cylinder 5 as it is, and therefore the oil does not overflow into the fixed tank 1 and overflow from the fixed tank 1. It is possible to prevent a fire from occurring.

Although the valve body 16 is raised by the biasing force of the spring 13 to close the valve hole 8 when the lid 21 is opened in the above embodiment, the valve body 1 is not always constructed in such a configuration.
6 does not need to be operated, for example, the lid 21 and the valve body 16
When the lid 21 is opened, the valve body 16 and the valve body 16 are connected by a link mechanism.
Can be moved to close the valve hole 8. In the case of the structure in which the valve element 16 is interlocked with such a link mechanism, it is not necessary to provide the pack receiver 12 or the spring 13 in particular.

[Effect of the Invention] As described above, according to the present invention, since the oil is supplied to the fixed tank of the oil heater by using the disposable type oil pack, the oil is supplied to the cartridge tank one by one. It is possible to handle it conveniently without the hassles and the stains on hands and surroundings with oil. Even if a hole is formed in the oil pack during use of the oil pack, the oil can be prevented from excessively flowing into the fixed tank and an unexpected fire can be avoided.
