Description

[Detailed Description of the Invention] The present invention relates to a water level display device that allows the water level in a container such as a pot to be confirmed from the outside.

Generally, in order to make the water level inside a container such as a pot visible from outside the body, a transparent tube is provided on the outside of the container, this transparent tube is connected to the top and bottom of the container, and a through hole is provided in the body. The structure is such that the transparent tube can be viewed visually. The transparent tube shows the water level at the same height as the water level inside the container, but in order to make it easier to check this water level, a display board with a striped pattern printed on it is installed between the transparent tube and the container. The pattern changes due to the lens action of water. Conventionally, this display board has a U-shaped horizontal cross section and is provided so as to surround the container side of the transparent tube, but this has the disadvantage that the mounting structure of the display board is complicated and assembly workability is poor. In addition, the display board tends to tilt, resulting in poor appearance, and in extreme cases, it may not function as a display board.

In response, it has been proposed to attach a display board to the side of the container. In this case, a display board can be easily installed, but the display board may tilt as in the case described above, and furthermore, the display label may peel off or discolor due to large temperature changes in the container. It was hot.

The present invention solves the drawbacks of the above-mentioned conventional water level display devices, and embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is the body of the electric heating pot.
A spout 2 is fixed to its upper end, and a base 3 is fixed to its lower end.
is fixed. 4 is a handle rotatably provided on the spout 2; 5 is a lid pivotally supported at the rear of the spout 2;
6 is a lock knob for fixing the lid 5 to the spout 2. Note that the lid 5 has a built-in pump mechanism (not shown) for supplying hot water. 7 is body 1
A cylindrical container with a bottom is housed in the container 7. At the upper and lower parts of the front surface of the container 7, there are protruding tubes 8 that protrude outward.
is formed. Reference numeral 9 denotes a transparent tube, and its upper and lower ends are connected to the protruding tube 8 via a flexible connecting tube 10 made of silicone rubber or the like. Reference numeral 11 denotes a display plate, and cutout portions 12 that engage with the protruding tube 8 are formed at the upper and lower ends. This display plate 11 is pressed by press-fitting the connecting pipe 10 into the protruding pipe 8, and the connecting pipe 10 and the container 7 are pressed together.
is held in between. 13 is a display frame attached to the front part of the body 1, and a display window 13a substantially coincides with the vertically elongated through hole 1a formed in the front part of the body 1.
is formed. 14 is body 1 and display frame 13
This is a transparent plate sandwiched between the holes 1a and 1a, which covers the through hole 1a and prevents dirt and the like from entering the body 1 through the through hole 1a. Note that the through hole 1a and the display window 13a are located on the outside of the transparent tube 9, so that the transparent tube 9 can be visually viewed from outside the body 1 through the transparent plate 14. 15 is a heater attached to the lower part of the outer periphery of the container 7.

In the above configuration, when water is injected into the container 7, the water flows into the transparent tube 9 through the protruding tube 8 and the connecting tube 10 at the bottom, and the water level in the transparent tube 9 becomes the same height as the water level in the container 7. , transparent plate 14 from outside the body 1
visible through. At this time, the diagonal striped pattern printed on the display board 11 appears to be deformed by the lens action of the water in the transparent tube 9, making it easy to check the water level. In addition, the display board 11 has notches 12 formed at its upper and lower ends and is engaged with the protruding tube 7, so that the display board 11 is not installed at an angle, giving it a good appearance. Further, since the display plate 11 is attached to the container 7 by being pressed by the connecting pipe 10, the attachment work is easily performed.

As shown in FIG. 3, when the upper end of the display plate 11 is engaged with a positioning rib 2a formed on the spout 2, misalignment between the spout 2 and the container 7 during assembly can be prevented. can. In the above embodiment, a diagonal striped pattern is printed on the display board, but the same effect can be achieved even if the display board is made plain and a similar pattern is provided on the back side of the transparent tube.

As described above, according to the present invention, notches are formed at the upper and lower ends of the display board that is provided between the transparent tube and the side surface of the container to clearly show the water level in the transparent tube, Attaching the display board is extremely difficult because the display board is engaged with protruding tubes located above and below the side surface of the container and protrudes outward, and the display board is pressed against the side surface of the container by the connecting pipe. This is easy to do, and by engaging the notch of the display board with the protruding tube, the display board will not be installed at an angle, and there will be no misalignment with the transparent tube. ,
A water level display device with good appearance can be provided. Furthermore, even if the liquid entering the transparent tube is a transparent liquid such as water, if a striped pattern is placed on the display board, the striped pattern will appear deformed by the lens action of the water in the transparent tube, making it easy to check the water level. However, since it only costs one additional display board,
It has various practical effects such as being inexpensive.
