Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid amount display device, and for example, to a device that detects and displays the amount of liquid fuel and water mixed in the liquid fuel in a liquid fuel combustion device such as a kerosene stove.

Petroleum, which is used as a liquid fuel for kerosene stoves, cannot avoid contamination with some water, and this water can cause problems such as ignition failure, incomplete combustion, and tank corrosion.
Conventionally, various measures have been taken to detect and discharge water.

However, in order to detect the amount of liquid fuel as well as the amount of water mixed in the liquid fuel, conventional devices must be installed separately, making installation difficult and requiring a large number of parts. This will increase costs.

The present invention attempts to improve on these points by using only one float, which has a specific gravity smaller than that of liquid fuel such as kerosene, and can detect and confirm liquid fuel and water. This is how it was done.

Next, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a flat fuel tank, and one bottom of this fuel tank 1 is recessed with a circular saucer portion 2, and the other bottom is recessed with an annular supply portion 3. 2
A flow path 4 is provided at the bottom of the fuel tank 1 between the fuel tank 1 and the supply section 3.
is recessed.

A fuel supply tank 5 as a fuel supply section is detachably provided at the top of one of the fuel tanks 1, and a fire pan section 6 having a combustion wick is provided at the top of the other supply section 3 as a combustion section. A combustion cylinder (not shown) is removably provided on the fire pan 6.

Then, liquid fuel such as kerosene is supplied from the fuel supply tank 5 onto the saucer part 2 of the fuel tank 1 at a constant level, and the fuel is led to the supply part 3 through the flow path 4.
The combustion occurs in the fire pan 6 using a combustion wick.

A circular reservoir 7 is recessed in the middle of the flow path 4 at the bottom of the fuel tank 1, and a drain pipe 8 is vertically disposed at the center of the lower end of the reservoir 7. A drain cap 9 is removably screwed onto the drain cap 9.

A gauge body 10 is provided on the upper surface of the fuel tank 1 above the reservoir 7 .

The gauge main body 10 has a flat frame 11, and an edge piece 12 is integrally formed on the outside of the front opening of the frame 11.

A display plate 14 made of a glass plate or the like is attached to the outer surface of the edge piece 12 via a backing 13, and a holder 15 attached to the edge piece 12 is attached to the outer edge of the display plate 14. has been done.

A transparent first display section 14a that displays the amount of liquid fuel as the liquid to be detected is formed in the horizontal direction in a slightly arc shape on the display board 14, and this first display section 1
A transparent second display section 14 that displays water at the middle lower part of 4a
b is formed.

Further, a frame cylindrical portion 16 is integrally protruded from the lower rear end of the frame 11, and this frame cylindrical portion 16 is fitted and fixed to the upper surface of the fuel tank 1 via a backing 17.

A support frame 18 is vertically installed at the rear lower part of the frame cylinder part 16 in the gauge main body 10, and a shaft body 19 is provided at the front of the lower end of the support frame 18.
is installed protrudingly.

A collar 20 is interposed in the middle of this shaft body 19, and a first isodicator 21 for fuel is mounted at the rear and a second indicator 22 for water is rotatably mounted at the front. .

The first indicator 21 and the second indicator 22 have pointer portions 23 and 24 located inside the frame 11, facing upward from the pivoting base and forward from the upper end.

An arm 25 projects from the pivoted base of the first indicator 21 toward one side, and a float 26 located within the reservoir 7 is attached to the tip of the arm 25.

The float 26 in this first indicator 21 has a specific gravity smaller than that of liquid fuel such as kerosene, so that it floats on the liquid fuel.

Further, a support piece 27 is provided protruding from the pivoted base of the second indicator 22 to one side, and a stopper 28 is provided at the upper end of the support piece 27 and faces onto the arm 25 of the first isosicator 21. A weight 29 is attached to the lower end of the support piece 27.

This weight 29 is set to be heavier than the buoyancy of the float 26 in liquid fuel minus the weight of the float 26, and lighter than the buoyancy of the float 26 in water minus the weight of the float 26. There is.

Note that 30 is the front plate of the entire device, and 31 is a window hole in the front plate 30.

In such a configuration, the liquid fuel is supplied to the fuel tank 5.
The fuel is supplied into the fuel tank 1 via the saucer section 2 at a constant level at all times, is supplied to the supply section 3 via the flow path 4, and is combusted in the fire tray section 6.

At this time, if only pure fuel is supplied into the fuel tank 1, the float 26 floats and operates the first indicator 21, as shown in FIG.

At this time, the arm 25 of the first indicator 21 hits the stopper 28 of the second indicator 22 equipped with the weight 29 set to the above value, and the indicating part 23 of the first indicator 21 It stops when the fuel indication zone on the display section 14a is full, and displays the amount of fuel up to the constant oil level.

Additionally, if water is mixed with the fuel and supplied, the water will
From there, it reaches the reservoir section 7 via the flow path 4, where it accumulates.

As a result, as shown in FIG. 6, the float 26 rises further from the position in the case of fuel, the first indicator 21 pushes up the stopper 28 part of the second indicator 22, and the second indicator 22 The second display section 14b, which is the water amount indication zone of the display board 14, is rotated to display the water amount.

When the water has accumulated more than the specified amount, drain the drain cap 9.
and drain the water from drain 8.

According to the present invention, when used in an oil stove or the like, the first indicator is activated by a float activated by fuel to detect and display the amount of fuel, and the first indicator is activated by water in conjunction with the first indicator. 2 indicator can be activated to detect and display the amount of water. Therefore, the amount of fuel and water contamination can be checked at the same time, preventing ignition failure, incomplete combustion, tank corrosion, etc. due to water contamination. , can be prevented.

Furthermore, one float can serve both as an indicator for the amount of fuel and water, and the structure is simple and assembly is easy, resulting in low cost.
