Description

[Detailed description of the invention] <Industrial field of application> This invention relates to an oil level gauge for an kerosene stove that can check the remaining burning time.

<Prior art> Conventionally, there is a device for displaying or confirming the possible combustion time according to the amount of remaining oil in the oil tank of an oil stove, as seen in Publication No. 1983-25549.
To explain this in Figure 1, 1 is the oil level gauge and pointer 2
, a number display 3 indicating the amount of remaining oil, and a time display 4 indicating the combustion time, and indicates the amount of remaining oil and the combustion time as the pointer 2 moves up and down.

<Problem that the invention aims to solve> In this conventional example, there is a one-to-one correspondence between the amount of residual oil and the combustion time, so it can only be adopted when the amount of fuel consumed per hour of the kerosene stove is determined to be approximately constant. However, it was inconvenient because it could not be used when the combustion state was variable to large, medium, or small firepower.

<Means for solving the problem> An oil level gauge is provided that uses a pointer that moves up and down in the vertical direction to indicate full and empty oil levels, and the combustion time is sequentially measured in the horizontal direction perpendicular to the bottom of the oil level gauge. A longer time display is provided, and a small heat power display line, a medium heat power display line, and a high heat power display line are sequentially written in direct proportion to the angle of inclination on the current combustion display section between the oil level gauge and the time display. The present invention relates to an oil level gauge for an kerosene stove, which is characterized in that the time display is read vertically below the intersection of the horizontal position of the pointer and each heating power display line.

<Operation> When the oil tank is refilled with fuel, the pointer 2 of the oil level gauge 1
will display the amount of oil.

If the well-known combustion operation is performed in this state, the oil level will drop, and the indicator 2 will also drop, but at this time, when the user wants to know how many hours of combustion remain, the user can check the current combustion state. For example, when a large fire is being burned, look at the horizontal position of the pointer 2 and see the large fire power display line 8.
Check the intersection with

Next, by visually following the point vertically downward from the intersection of the large firepower display lines 8 and visually checking the time on the time display 4, it is possible to judge whether or not the next digit of combustion is possible.

Of course, the determination is made in the same way in the case of medium-fired combustion and in the case of small-fired combustion.

<Example> 1 is a vertically elongated oil level gauge used for oil stoves as in the conventional example, and approximately in the center is a pointer 2 that moves up and down in the vertical direction, with a full level F at the top and a pointer 2 at the bottom. Notifies the oil amount of empty amount E.

At the bottom of the oil level gauge 1, there is provided a time display 4 which shows the combustion time in the horizontal direction perpendicular to the bottom, and the time is set to a long time as it moves outward sequentially from 0 to 9 hours. .

In addition, kerosene stoves allow you to change the combustion state according to your preference, such as large-power combustion, medium-power combustion, and small-power combustion.

5 is the current combustion display section, and between the oil level gauge 1 and the time display 4, there is a small heat power display line 6 in direct proportion starting from 0, and a medium heat power display line 7 with a different slope from this.
A large heating power display line 8 is provided with a different slope from this, and the large heating power display line 8 has an inclination angle that is sequentially larger than that of the small heating power display line 6.

This angle of inclination is set in advance according to the combustion consumption amount confirmed through experiments.

Also, in the state shown in Fig. 2, if the current combustion state is high power combustion, visually check the horizontal position of the pointer 2 as shown by the broken line to confirm the intersection with the high power display line 8, and then visually check the horizontal position of the pointer 2 as shown by the broken line. If you look vertically downward from the intersection of the large fire power display lines 8 and check the time on the time display 4, you can judge that you can burn for about 3 hours.

If the current combustion state is medium-power combustion, if you check in the same way as above, it will be determined that you can burn for about 5 hours, and if the current combustion state is low-power combustion, if you check in the same way as above, you will find that you can burn for about 7 hours. It is determined that combustion can be performed for about an hour.

Also, how to read the pointer 2 and the firepower display lines 6, 7, 8, and how to check the time display 4 is of course explained in the manual that comes with the kerosene stove.

<Effect of the invention> An oil level gauge 1 is provided for indicating oil levels of full level F and empty level E using a pointer 2 that moves up and down in the vertical direction.
A time display 4 in which the combustion time gradually increases is provided in the horizontal direction perpendicular to the lower part of the screen, and a small heat power display line 6 and a medium heat power display are provided in the current combustion display section 5 between the oil level gauge 1 and the time display 4. Line 7 and large fire power display line 8 are sequentially marked in direct proportion to the inclination angle, and read the time display 4 vertically below the intersection of the horizontal position of pointer 2 and each fire power display line 6, 7, 8. Because of this feature, the pointer indicates the amount of oil remaining in the oil tank, and at the same time, it is possible to judge how many hours of burning time is left at each firepower.

On the other hand, you can determine how much kerosene will be consumed if the fuel is burned for how many hours at each heating power.

Also, this allows for planned firepower adjustment and eliminates the possibility of running out of oil midway.

In addition, since the combustion time indicated by the fire power display and the time display has a judgment accuracy that allows a rough estimate, even if there is some variation in the oil level gauge, the error can be sufficiently absorbed.

In addition, with kerosene stoves, where the amount of fuel consumed changes significantly due to switching or adjusting the heating power, it was difficult to judge how many hours of fuel remaining in the oil tank could be burned. It can be determined reliably with a simple structure.
