Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for displaying a residual oil amount of an oil combustor using a cartridge tank.

[0002]

2. Description of the Related Art An overturned cartridge tank has a cap with a valve attached to a saucer of an oil tank of an oil combustor.
When the fuel in the oil tank is used, air flows into the cartridge tank, and the used amount of fuel is supplied from the cartridge tank. The inside of the cartridge tank has a negative pressure, and if a small air hole is made, all the fuel in the cartridge tank flows into the oil tank and overflows. Therefore, mounting a full-scale oil meter with a large opening in the cartridge tank will cause a problem in which fuel leaks out if the airtight packing attached to this opening is deteriorated. In general, a structure in which a small oil volume window is installed at a minimum was used.

For this reason, the above-described oil amount window of the cartridge tank merely confirms whether or not a certain amount of fuel remains. Generally, the details of how much fuel is currently remaining in the cartridge tank are described in detail. It cannot be known. There is also a proposal to balance the weight of the cartridge tank and the spring to know the amount of oil at this balance position, but in this case, when the position of the cartridge tank moves up and down, the oil level of the oil tank changes. The total amount of fuel flowing into the tank fluctuated, and if the oil combustor fell, fuel could leak from the oil tank, which was dangerous.

Accordingly, in this system, a system has been put into practical use in which the weight of a cartridge tank is measured by a semiconductor weight sensor in which the height position of the cartridge tank does not change, and this data is converted into a fuel capacity and displayed. Currently, only this method can display the amount of oil in the cartridge tank.

[0005]

However, the semiconductor weight sensor used in the above proposal is extremely expensive, and it is not practical to attach it to an inexpensive, popular type oil combustor in terms of selling price. It was extremely difficult. For this reason, the popular type oil combustor detects the weight of an empty cartridge tank or the oil level of the oil tank,
Lamps and warning sounds were used to indicate that the fire would soon be extinguished due to lack of fuel.

[0006] The above structure is substantially the same as the method of knowing the amount of oil using the oil amount display window of the cartridge tank. There was no warning, and he had to rush to arrange refueling.

[0007]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and includes a cartridge tank 1 for mounting a cap 2 with a valve on a filler port 1a, and a receiving tray for inserting the cap 2 with a valve of the cartridge tank 1. Oil tank 3 having 3a
And a burner 4 that supplies and burns fuel from the oil tank 3, and is provided with a fuel pump 6 attached to a fuel pipe 5 that connects the burner 4 and the oil tank 3. The body A is provided with an oil amount display means 7 of the cartridge tank 1 in which a plurality of display portions 7a are assembled, and an oil amount data input means 8 of the cartridge tank 1 and an output of the combustion amount adjusting means 9 of the oil combustor. In response to this, the combustion amount calculating means 10 for driving the fuel pump 6, the oil amount storing means 11 for storing the output of the oil amount data input means 8, and the combustion amount calculating means 10 and the oil amount storing means 11 A residual oil amount calculating means 12 to be input is provided, and the calculation result of the residual oil amount calculating means 12 is output to the oil amount display means 7.

Further, in this proposal, the approximate oil amount of the cartridge tank 1 is displayed by calculation in the control unit. Therefore, an oil amount detector 13 is attached to the cartridge tank 1 or the oil tank 3 to detect the oil amount. The accuracy is improved by inputting the output of the unit 13 to the residual oil amount calculating means 12 and correcting the output data to the oil amount displaying means 7 by the residual oil amount calculating means 12.

Further, the replenishment of the fuel in the cartridge tank 1 is not limited to the full replenishment at all times, and sometimes the fuel is small and the refueling cannot be performed to the full. The storage amount of the oil amount storage means 11 is changed every time the oil amount data input means 8 is operated, and the display state of the plurality of display portions 7a is also changed. Can be displayed on the screen.

[0010]

The replenishment of fuel to the cartridge tank 1 is almost always performed until the fuel is full, and the amount of oil stored immediately after refueling is always constant, since only the designated cartridge tank 1 can be used. Further, in this type of oil combustor, fuel is sent to the burner 4 by the fuel pump 6, so that even if there are several operation modes of the fuel pump 6,
The total amount of fuel sent to the burner 4 can be calculated from the total running time for each type.

According to the present invention, if the fuel state is set when the cartridge tank 1 is set by the oil amount data input means 8 and the operation of the oil combustor is started as it is, the operation of the fuel pump 6 is started. The remaining amount of fuel 1 is displayed by the oil amount display means 7. For this reason, it is no longer possible to suddenly sound an alarm when the fuel is almost exhausted and to rush to arrange refueling as in the related art.

Further, the present invention not only always corresponds to the full capacity of the cartridge tank 1, but also
By operating a plurality of times, several of the plurality of display portions 7a of the seven-stage oil amount display hand can be selected, so that not only the fullness of the cartridge tank 1 but also the Even when the amount of fuel is not enough, the amount of fuel remaining in the cartridge tank 1 can be displayed almost accurately by operating the oil combustor.
