Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables safe use even if the size of the oil tank for supplying oil to the burner is reduced.

[0002]

2. Description of the Related Art There is a type in which an oil tank or a burner is provided in the frame of an oil combustor, and a removable cartridge tank is used to supply oil to the oil tank. This oil tank structure attaches an oil pan from the top plate toward the inside of the oil tank, and by attaching the cap of the cartridge tank to the oil pan, the on-off valve built into the cap is pushed open to remove the oil in the cartridge tank. To refuel.

That is, since the opening / closing valve provided in the cap of the cartridge tank is pushed open by the protrusion arranged in the oil receiver, air flows into the cartridge tank, and instead the oil in the cartridge tank is transferred to the oil receiver. When the oil level of the oil tank rises and reaches the tip of the cap, air cannot flow into the cartridge tank, and the oil tank holds a constant oil level.

If the oil level at this time is made as low as possible and the shape of the oil tank is made large, the space above the oil tank becomes large, and even if the oil combustor should fall over, the oil tank inside The oil collects on the side of the oil tank, which is located below, and the oil level at the time of this fall is lower than the continuous part with the burner and the oil pan to prevent oil from leaking out from the oil tank.

[0005]

In order to prevent the oil from leaking from the oil receiver attached to the top plate of the oil tank or the continuous portion with the burner at the time of tipping, these oil leaks may occur. It is necessary to arrange a certain part in the center of the top plate of the oil tank as much as possible, and in the case of a fall, the structure is such that the total amount of oil in the oil tank is collected between the side wall of the oil tank and the bottom plate and the top plate.

By the way, the recent oil combustor tends to be compact and has a large calorific value, and if the basic structure such as a burner is made small, it may seriously affect combustion. Therefore, a heat shield structure is used. The gap between the burner portion and the frame is narrowed. As a result, the projected floor area of the oil combustor becomes narrower, and it is necessary to make the oil tank attached to the combustion section smaller.

However, as described above, in consideration of a fall accident of the oil combustor, the oil tank cannot be arranged near the side portion of the oil tank, which is a continuous portion with the cartridge tank. Even if the frame side walls are brought close to each other, a large gap is created between the cartridge tank and the frame side wall, and it is one of the problems to reduce the size when aiming at downsizing of the frame.

[0008]

According to the present invention, even an oil tank designed to be extremely small can ensure safety, and an oil tank 2 for supplying fuel to a burner 1 is provided in the frame of an oil combustor. The upper plate 2a of the oil tank 2 has an oil pan 3 fixed to the inside of the oil tank 2, and a cap 4a of a cartridge tank 4 for supplying oil to the oil tank 2 is provided with an on-off valve 5 inside. The cap 6 of the cartridge tank 4 is attached to the oil receiver 3 of the oil tank 2 into which the cap 6 of the cartridge tank 4 is fitted. Installed on the oil pan 3, the cartridge tank 4 to the oil tank 2
In an oil combustor that supplies oil to the oil receiver 3, an upper end plate 7 having an opening 7a having a size allowing the cap 6 of the cartridge tank 4 to be inserted is attached to the upper end of the oil receiver 3, and the opening of the upper end plate 7 is provided inside the oil receiver 3. The protrusion 3 has a shape larger than 7a.
A movable plate 8 to which a is attached is provided, and a spring member that presses the movable plate 8 against the upper end plate 7 between the movable plate 8 which is guided up and down by the tubular wall surface of the oil receiver 3 and the bottom plate of the oil receiver 3. 9 is provided, and when the cartridge tank 4 is attached to the oil receiver 3, the spring member 9 is compressed by the weight of the cartridge tank 4 to move the movable plate 8
Is provided near the bottom plate of the oil receiver 3, and when the cartridge tank 4 is taken out, the spring member 9 pushes up the movable plate 8 to close the opening 7a.

[0009]

Since the cartridge tank 4 has a constant weight even when the cartridge tank 4 is empty, the movable plate 8 urged by the spring material 9 can be pushed down by this weight, and the projection 3a provided on the movable plate 8 at this depressed position. Can open and close the on-off valve 5 of the cap 6 to supply oil from the cartridge tank 4 to the oil tank 2.

On the other hand, when the oil combustor falls, the cartridge tank 4 pops out, or the movable plate 8 pressed by the gravity of the cartridge tank 4 floats up by the force of the spring material 9 and pushes out the cartridge tank 4.
The movable plate 8 is in contact with the opening 7a of the upper end plate 7 to close it.

Therefore, even if the oil receiver 3 of the oil combustor falls down, the opening 7a is closed at the same time when the cartridge tank 4 is removed, so that the oil receiver 3 is replaced by the oil tank 2.
Even if it is installed close to the side wall of the oil, the oil will almost never leak and the safety will be improved.

The inner edge of the mounting hole 16a provided in the recess 16 is sandwiched between the collar portion 3b and the locking claw 3c, and the oil receiver 3 is fixed to the upper surface plate 2a of the oil tank 2.

Reference numeral 7 denotes an upper end plate of the oil receiver 3, that is, an upper end plate screwed and fixed to the upper surface of the collar portion 3b, and 7a denotes an opening formed in the center of the upper end plate 7 and having a size allowing the cap 6 of the cartridge tank 4 to be inserted. Is a movable plate provided inside the oil receiver 3 so as to be vertically movable. The movable plate 8 has a shape larger than the opening 7a of the upper end plate 7 and is guided by the side wall of the oil receiver 3 to move up and down.

Reference numeral 3a denotes a protrusion attached to the movable plate 8 toward the opening 7a of the upper end plate 7, and 9 denotes a protrusion provided between the movable plate 8 and the bottom plate of the oil receiver 3 to direct the movable plate 8 to the upper end plate 7. When the cap 6 of the cartridge tank 4 is attached to the oil receiver 3, the movable plate 8 is pushed toward the bottom plate of the oil receiver 3 because the spring material 9 is compressed by the weight of the cartridge tank 4. The projection 3a provided on the movable plate 8 in the oil receiver 3 pushes the open / close valve 5 to open the air into the cartridge tank 4, and instead the oil in the cartridge tank 4 flows into the oil receiver 3. The oil can be supplied to the oil tank 2.

On the other hand, when the cartridge tank 4 is taken out from the predetermined position of the frame body 10, the spring member 9 pushes up the movable plate 8 to close the opening 7a, and the cartridge tank 4 is removed. In this state, the oil tank 2 becomes a sealed tank.

In the oil combustor using the cartridge tank 4 as described above, the oil level in the oil tank 2 is always determined by the tip position of the cap 6 of the cartridge tank 4, and the oil combustor falls over. When doing so, the oil contained in the oil tank 2 may overflow from the oil receiver 3 or the like of the upper plate 2a. Therefore, the amount of oil constantly contained in the oil tank 2 is reduced, and The structure is attached to the center as much as possible to prevent overflow. However, attaching the oil receiver 3 near the center of the oil tank 2 increases the size of the gap between the cartridge tank 4 and the frame 10, which is the reason why the size of the frame 10 of the oil combustor cannot be made too small. .

When the cartridge tank 4 is removed, the oil tank 2 according to the present invention becomes a closed tank by the action of the movable plate 8. Therefore, even if the inner surface of the movable plate 8 is covered with oil at the time of tipping over, the oil tank 3 will not Almost no leakage. Therefore, even if the oil receiver 3 is installed near the side wall of the oil tank 2, the safety performance can be ensured, and the side plate of the oil tank 2 is placed at a position corresponding to the minimum size of the cartridge tank 4 and the side plate of the frame 10. Even if it is positioned, there is almost no oil leakage when it falls, and it can be used safely.

[0021]

As described above, according to the present invention, the cartridge tank 4 is disengaged from the oil receiver 3 when the oil combustor falls.
Since the opening 7a of the oil receiver 3 is closed by the movable plate 8 to form a closed tank, even if the oil receiver 3 is installed near the side wall of the oil tank 2, there is almost no oil leakage, and it is sufficient. The safety was secured.

On the other hand, since the oil receiver 3 can be attached near the side wall of the oil tank 2 in this manner, the dimensions of the cartridge tank 4 and the side plate of the frame can be reduced, and the frame of the oil combustor is designed small. Then, it has become possible to meet the recent demands of the operator.
