Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil metering device for a drop type cartridge tank such as an oil stove.

[0002]

2. Description of the Related Art In order to detect the amount of oil in a drop-type cartridge tank used for an oil stove or the like, a float is directly incorporated into the tank, and the displacement of the float is directly viewed from the outside. Most of them look straight.

Although there is a small number, there is a structure for displaying the change in weight by balancing the relationship between the weight of the tank containing the fuel and the spring and the like.
No. 0 shows a structure provided with a vertical moving plate that moves up and down in response to a change in weight at the lower part of the tank, a rack and pinion that transmits and receives this in relation to vertical movement, and a pointer.

In Japanese Utility Model Publication No. 46-11179, an oil reduction limit mark is displayed on the body of the tank body, and when the tank body is pushed up by a spring provided in the tank tray, the limit mark appears outside the tray. The resulting structure is shown.

[0005]

An oil stove equipped with a cartridge tank has a system for changing the combustion amount and igniting and extinguishing the fuel supplied by a drop while the on-off valve is open and closed. There is a method of adjusting the combustion by providing a lower tank that receives fuel once and moving up and down the combustion wick that sucks up the fuel in this lower tank.In the latter method, a saucer is placed above the lower tank and It is common to mount a cartridge tank upside down to maintain a constant oil level.

Therefore, there are the following problems in adopting the structure for detecting and displaying the decrease in the tank oil amount in the structure in which the lower tank is provided with the tray. That is, since the valve of the cartridge tank is pushed open by the valve opening shaft that is projected in the tray,
If the cartridge tank is lifted by sensing the oil loss in the cartridge tank, the valve will also close, and the fuel supply may be stopped even if there is still a large amount of residual oil in the cartridge tank depending on the accuracy variation of the spring. There is a drawback that it may stop and the combustion duration will be shortened.

[0007]

In order to solve the above problems, the present invention uses up the fuel in the cartridge tank by raising the cartridge tank and the tray together when the amount of oil in the cartridge tank decreases. It was done like this. That is, a cartridge tank 1 is equipped with a cap 3 having a valve 2, and the cap 3 is attached to the tray 5 of the lower tank 4, and the valve opening shaft 6 protruding in the tray 5 pushes the valve 2 open. In the above, in the cartridge tank oil metering device, there is provided a raising mechanism A for raising the cartridge tank 1 and the tray 5 together when the amount of oil in the cartridge tank 1 decreases.

The raising mechanism A may measure the residual oil amount in the cartridge tank 1 which starts its operation when the oil amount in the cartridge tank 1 reaches a constant oil reduction amount.

As the lifting mechanism A, the bottom portion 4 of the lower tank 4 is
It suffices to provide a spring 7 mounted between a and the tray 5 to lift the tank 1 against the weight of the cartridge tank 1 when the amount of oil decreases.

As another example of the raising mechanism, when the cartridge tank 1 is mounted on the tray 5, the cap 3 and the tray 5 are tightly attached to each other, and the cartridge tank 1
If a tank lifting spring 7a is provided on the outside of the tank, the tank 1 and the tray 5 can be lifted together.

[0011]

With the cartridge tank 1 with the cap 3 side facing upward, the cap 3 is removed from the tank 1 and oil is supplied by an appropriate method. After that, the cap 3 is reattached, the cap 3 side is faced downward, and the cap 3 is attached on the receiving tray 5 of the lower tank 4, the valve 2 of the cap 3 is pushed open by the valve opening shaft 6 projecting from the receiving tray 5,
The oil in the cartridge tank 1 flows to the lower tank 4 side, and is continuously discharged until the oil surface on the lower tank 4 side becomes the opening of the cap 3.

When the oil on the lower tank 4 side is used for the combustion of the oil stove, the oil level of the lower tank 4 drops, and a gap is created between the oil and the cap 3 of the cartridge tank 1, air enters the cartridge tank 1. Instead, the oil flows out by the reduced amount, and this operation is repeated thereafter.

In the present invention, when the oil in the cartridge tank 1 is used, the weight of the tank 1 is reduced, and the lifting mechanism A raises the cartridge tank 1 and the tray 5 together. By this raising operation, the amount of oil in the cartridge tank can be known.

When the cartridge tank 1 has a large storage capacity, the lifting mechanism A has its lifting force killed, but when the oil reduction reaches a certain limit (that is, 20% or less of the tank capacity).
If it is set so that the residual oil amount in the cartridge tank 1 can be accurately known.

In this way, when the internal capacity of the cartridge tank 1 becomes small, it is notified to the outside, but while the cartridge tank 1 still has a residual oil amount, the valve opening shaft 6 of the tray 5 is opened.
The valve 2 is always pushed open constantly, and the oil is allowed to flow out until the oil in the cartridge tank 1 is completely exhausted.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure will be described below with reference to the drawings showing an embodiment. Lower tank, which supplies fuel to
5 is a saucer mounted on the upper surface of the lower tank 4, and 6 is a saucer 5.
It is a valve opening shaft that is provided so as to project upward inside the. After the oil is supplied into the cartridge tank 1, the cap 3 is tightened and the cartridge tank 1 is installed upside down on the pan 5, so that the valve 2 is pushed open by the valve opening shaft 6 and the oil in the cartridge tank 1 is panned. It is supplied to the lower tank 4 via 5 and is continuously replenished while the oil surface of the lower tank 4 and the opening of the cap 3 maintain a constant oil surface.

A is a lifting mechanism for lifting the cartridge tank 1 when the amount of oil in the cartridge tank 1 reaches a certain limit (usually about 20% of the tank capacity), and this lifting mechanism A is shown in FIG. As shown in FIG. 2, a spring 7 is provided between the bottom portion 4a of the lower tank 4 and the tray 5, and the force of the spring 7 is applied to the cartridge tank 1 when the internal volume of the cartridge tank 1 is below a certain amount (20%). 1 and saucer 5
Can be lifted together.

Alternatively, when the engaging piece 9 is formed on the receiving tray 5 with an elastic material and the cap 3 of the cartridge tank 1 and the receiving tray 5 are tightly attached by the engaging piece 9, Tank lifting spring 7 between the lower tank 4 and the upper surface
a may be provided, and the cartridge tank 1 and the tray 5 can be lifted together when the internal volume of the cartridge tank 1 becomes a certain amount or less.

Reference numeral 8 denotes a combustion section connected to the lower tank 4, which is shown in FIG.
Illustrates a combustion cylinder provided on the core lifting device. 10
Is a display unit that is interlocked with the weight change (vertical movement) of the cartridge tank 1, and can be detected outside the machine such as an oil stove.

[0020]

The present invention has the above-described structure and operation. When the cartridge tank 1 is raised by detecting that the internal volume of the cartridge tank 1 has been reduced, the tray 5 is also put together. Since the temperature rises, the relational dimension between the cap 3 and the tray 5 does not change, and there is an advantage that oil discharge to the lower tank 4 is continued.

When the cartridge tank 1 is lifted by sensing that the internal volume of the cartridge tank 1 has decreased, the lifting mechanism A causes the residual oil in the cartridge tank 1 to become small (about 20%). If you make it move,
The residual oil amount can be accurately displayed even if the moving distance of the cartridge tank 1 is reduced.

Therefore, there is a variation in accuracy of the lifting mechanism A, and although the cartridge tank 1 has a sufficient residual oil amount, even if the cartridge tank 1 is lifted, the oil outflow is stopped. The disadvantages of can be eliminated.
