Abstract

(57) [Summary] [Objective] The present invention relates to a residual fuel amount display device for a cartridge type fuel tank in an oil stove. [Structure] A U-shaped pipe with a hollow inside and different left and right leg lengths is placed inside the cartridge type refueling tank so that the bottom of the U-shaped pipe comes up when the oil stove is in use. Install. A display portion is provided so that the inside of the bottom portion or the foot portion of the U-shape can be seen from the outside of the cartridge type fuel tank.

Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention relates to an oil stove refueling tank that allows the remaining amount of kerosene to be easily known from the outside even when the oil stove is in use.

[Prior Art] It is said that the conventional cartridge type oil tank of an oil stove cannot easily know the remaining amount of kerosene from the outside, and that it can be known that kerosene has been exhausted after emptying. Met. Therefore, even if the "wake-up timer" is set, kerosene runs out before the room warms up, or kerosene runs out late at night. At times like this, I often experience the disadvantage of having to refuel in the cold.

[Problems to be Solved by the Invention] The present invention makes it possible to easily know the remaining amount of kerosene from the outside even when the oil stove is in use. Therefore, it aims to eliminate the disadvantages from the past.

[Means for Solving the Problem] The means for solving the problems of the present invention will be described with reference to the drawings. (A) One leg of a U-shaped pipe 1 having a hollow interior and left and right legs having different lengths Is attached to one wall surface of the cartridge type refueling tank 2, and the other foot is attached to the other wall surface. Further, the bottom portion of the U-shaped pipe 1 is mounted so as to come to the upper surface when the fuel tank 2 is mounted on the oil stove. (B) A transparent material (for example, glass) for the U-shaped pipe 1 and that portion of the kerosene tank 2 so that the inside of the bottom portion or the foot portion of the U-shaped pipe 1 can be seen from the outside of the kerosene tank 2. Is used to set the display unit 3.

[Operation] Since the present invention is configured as described above, the kerosene surface 4 of the cartridge type refueling tank 2 is above the shorter foot 5 of the U-shaped pipe 1 while the oil stove is in use. In the above case, the kerosene filled at the time of refueling is still present inside the pipe 1 by the principle of sifon. When kerosene is consumed and the kerosene surface 4 is below the shorter leg 5, air flows into the U-shaped pipe 1 from the leg 5 and kerosene inside the pipe 1 flows out from the longer leg 6. To do. Then, the kerosene surface rises and the shorter leg 5 becomes below the kerosene surface 4 again, and the inflow of the air is stopped, but if the kerosene is further consumed, finally the type 1 of the pipe 1 All the kerosene inside will spill. Therefore, it is possible to know from the display unit 3 provided in the kerosene tank 2 that the kerosene has been exhausted to a certain amount.

[Embodiment] The present invention may be carried out as follows. (A) Attach both legs of the U-shaped pipe 1 to one wall of the kerosene tank 2 together. (B) Providing multiple types of U-shaped pipes 1 with different leg lengths so that the remaining amount of kerosene can be determined stepwise. (C) The portion where the remaining amount of kerosene can be seen (that is, the display portion 3) is not limited to the upper portion in the usage state of the oil stove, but may be the side portion. (D) In the U-shaped pipe 1, only the tip portions of the left and right feet may be inserted into the fuel tank 2 and the other portions may be provided outside. (E) The presence or absence of kerosene inside the U-shaped pipe 1 is converted into an electric signal and the state is displayed on the operating surface of the oil stove, or a sound is made to notify. Further, by marking a wall on the back side of the U-shaped pipe 1 which is visible from the outside, and by utilizing the lens effect with and without kerosene, the presence or absence of kerosene can be seen more easily.

[Advantage of Invention] Therefore, since the remaining usage time can be estimated by knowing the remaining amount of kerosene, it is possible to replenish kerosene before running out of kerosene and feeling cold.
