[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank with a full amount notification for informing the full amount at the time of refueling fuel with an electric informing means such as a buzzer.

[0002]

2. Description of the Related Art Heretofore, in this type, a buzzer that the amount of fuel supplied to a refueling tank is nearly full, as disclosed, for example, in Japanese Patent Laid-Open No. 61-101712. By using the electric notification means such as, for example, it is possible to easily know the full amount even in the replenishment in a dark place.

[0003]

In this prior art, however, since the alarm means is simply provided on the side wall of the refueling tank, the fuel oil may be spilled on the side wall when the supply hose pump or the like is unplugged. Alternatively, by removing the refueling tank from the combustion equipment and placing the refueling port side up for replenishment, the fuel adhering to the refueling port cap, etc. flows down to the side wall and wets the notification means composed of electrical parts. As a result, there is a problem that it causes failure such as contact failure and cannot withstand long-term use.

[0004]

This invention pays attention to this point and solves the above-mentioned drawbacks. Therefore, in particular, the configuration is informed that the amount of fuel oil supplied inward is at least near the full amount. In a structure provided with an electric full amount notifying means, a projecting wall for preventing fuel oil from flowing into the full amount notifying means is provided on an upper surface portion above the full amount notifying means.

[0005]

When the fuel supply to the fuel tank 1 is started through the supply pipe 29 of the hose pump (not shown), the rotary rod having the float 21 at one end, which floats on the oil surface near the full amount, is provided. 23 rotates about the shaft support portion 22 as a fulcrum, the magnet 24 provided on the opposite side faces the lead switch 25 provided in the main body, and by closing this, the buzzer 27 is closed. , Pi ... "
It sounds to notify the full amount.

[0006] Then, the supply is stopped and the supply pipe 29 is pulled out by the notification of the full amount. At this time, the fuel oil adhering to the tip of the supply pipe 29 drips onto the upper surface of the refueling tank 1. Since the winding-closing edge portion 4 which also functions as the projecting wall is formed and the full-quantity notifying means 20 is provided on the winding-closing edge portion 4 side, it is possible that the fuel flows down to the full-quantity notifying means 20.
Therefore, the full amount notifying means 20 is prevented from getting wet with fuel oil, and there is no fear of failure, and it can sufficiently withstand long-term use.

Reference numeral 20 denotes an electric full amount notifying means provided adjacent to the oil level meter 17, which is a float 21 which moves up and down according to the amount of floating oil on the oil surface, and the float 21. A rotary rod 23 which is provided at one end and is rotatable around a shaft support 22 as a fulcrum; and a lead switch 25 which is closed by facing a magnet 24 fixed to the other end of the rotary rod 23; When the lead switch 25 is closed, a signal is input to start output, and the output is counted for 5 seconds and then stopped. The microcomputer 26 receives the output from the microcomputer 26 for 5 seconds. A buzzer 27 that emits a warning sound and a lithium battery 28 that operates these electric components and that can be easily replaced are housed in one case.

The full amount notifying means 20 is attached so as to notify the full amount when the oil level display by the oil level gauge 17 reaches the substantially central position. Further, the oil level meter 17 and the full amount notifying means 20 are provided on the lid plate 3 side as described above, and the winding fastening edge portion 4 is provided on the upper surface portion 5 side which is the upper portion thereof.
Is located, and means 20 for notifying the full amount of fuel dropped on the upper surface portion 5
The full amount notifying means 20 is located inwardly of the winding edge 4 protruding outward, and the fuel oil overflows beyond the winding edge 4 as well. However, the fuel does not drip.

Further, the protruding wall is not limited to the winding edge portion 4, but may be formed by forming a convex portion protruding upward on the upper surface portion 5 of the refueling tank 1 toward the full amount notifying means 20 side. Alternatively, an L-shaped metal fitting or the like, which is a separate member, may be attached, that is, the fuel oil flowing or dripping on the upper surface portion 5 is blocked to fill the full amount notifying means 2
Anything that prevents 0 from getting wet with fuel oil may be used. Reference numeral 29 is a supply pipe such as a hose pump for supplying fuel.

Next, the operation of this embodiment will be described. When the fuel in the refueling tank 1 is exhausted and the fuel is replenished, first, the operation button 16 is pulled to open the refueling port 6 with one touch, and then the supply pipe 29 is inserted into the refueling port 6 to replenish the fuel, When the amount of oil in the refueling tank 1 reaches 75% of the internal capacity, the oil level display by the oil level meter 17 is started, that is, the oil level in the refueling tank 1 is displayed as it is on the display window 18. This allows the user to know the current amount of oil.

Further replenishment progresses and the oil meter 17 shown in FIGS.
When it reaches almost the center position, the float 21 that moves up and down according to the amount of oil moves upward and the magnet 24 at the other end re-opens.
When the lead switch 25 is closed and the lead switch 25 is closed, the full-volume notifying means 20 sounds an alarm sound "Pi-Pi ..." for 5 seconds to notify that the full-volume is nearly reached. The user may, upon hearing this, immediately stop the replenishment, or may replenish the fuel tank until the remaining half of the oil gauge 17 is no longer visible and then quit.

Therefore, by providing the two full-volume displays of the oil level meter 17 that visually appeals and the full-quantity notifying means 20 that appeals auditorily, it is possible to surely know the full-volume state, especially in a dark place or noise. Even when replenishing in a fierce place, you can know the full amount by utilizing the advantages of each display and notification means, there is no problem such as fuel oil overflowing and soiling the floor in any state, always use with peace of mind It is possible and easy to use even for visually and hearing impaired people. On the other hand, both the oil level meter 17 and the full amount notifying means 20 also display the empty state of the configuration, and in particular, when the full amount notifying means 20 performs the empty amount notification for 5 seconds, the refueling tank 1 is stored in the device. Even if it is done, the user can easily know the empty state,
It is extremely convenient that the full-volume notifying means 20 can also be used without providing any special vacant amount notification.

Next, when the supply pipe 29 is removed from the fuel supply port 6 after the fuel supply is completed, the fuel oil adhering to the supply pipe 29 drips onto the upper surface portion 5 of the fuel supply tank 1 and flows into the full amount notification means 20. However, in the present invention, since the winding tightening edge portion 4 which also functions as the projecting wall is formed on the full amount notifying means 20 side of the upper surface portion 5, it falls on the upper surface portion 5 as shown in FIG. The fuel oil is blocked by the winding edge 4,
It is prevented from flowing into the full amount notifying means 20, and even if the winding edge 4 is overrun, the full amount notifying means 20.
Means that the fuel is not sprayed because it is positioned inward of the end of the winding edge 4.

Therefore, it is possible to surely prevent a failure due to a contact failure or the like caused by the inflow of fuel oil from the outer surface portion of the full quantity notifying means 20 without oil countermeasures, and always use it with peace of mind. It is made and can withstand long-term use. Further, since the projecting wall that blocks the inflow of fuel oil is also used as the winding tightening edge portion 4 of the lid plate 3 that configures the fuel tank 1, there is no need to perform special processing or to attach another component, and the full amount notifying means 20 can be covered. This can be achieved by attaching it to the plate 3 side, and it has an extremely simple structure and is inexpensive.
