Description

[Detailed Description of the Invention] The present invention relates to an improvement of a water level display device in a pot.

Conventionally, in pots, a transparent water level pipe was installed upright from the lower side or bottom of the container via a water pipe and a rubber tube so that the water level inside the container could be visually observed from the outside, and a striped pattern was placed behind the water level pipe. A version with a back plate is provided.
This back plate has been attached to a metal fitting fixed to the outside surface of the container or to a metal fitting for attaching a water pipe, but both methods have drawbacks such as poor workability and increased costs.

The present invention was created in view of these drawbacks.
To provide a water level display device in which the upper end of a water level pipe is connected to the upper side surface of a container, in which a back plate can be easily attached without using the above-mentioned metal fittings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

FIG. 1 shows an electric pot equipped with a water level display device according to the present invention, in which a bottom body 2 is fixed to the lower part of a body 1 made of a thin metal plate, and a shoulder body 3 is fixed to the upper part.
A lid 4 containing an air pump (not shown) is provided on the top of the lid 4, which can be opened and closed by a hinge 5.

A stainless steel container 6 is housed and fixed inside the body 1, a band-shaped heater 7 is wrapped around the lower outer periphery of the container 6, and the periphery of the container 6 is covered with a heat insulating material 8. A water level pipe 9 made of a transparent glass tube is erected outside the heat insulating material 8, and a rubber tube 10 is attached to the upper end of the water level pipe 9.
The lower end of the water level pipe 9 is connected to the bottom surface of the container 6 via a rubber tube 12 and a water pipe 13. In addition, when the heater 7 is not wrapped around the lower outer periphery of the container 6, the lower end of the water level pipe 9 may be connected to the lower side surface of the container.

A window hole 14 is provided in the upper body 1 at a position corresponding to the water level pipe 9, and a water amount display panel 15 is attached to the outside of this window hole 14. A vertically long display window 16 is provided in the center of the water quantity display panel 15, and two display holes 1 for displaying current are provided at the bottom.
7 is provided. A lens 18 is fitted into the display hole 17, and a lamp 19 corresponds to the inside of the lens 18.

A back plate 20 is attached behind the water level pipe 9 as shown in FIGS. 2 and 3. That is,
The back plate 20 is made of a thin metal plate, has diagonal lines drawn on its front surface, has a hook-shaped hanger part 21 formed at its upper end, and has a roughly L-shaped retainer bent at right angles at its lower end. A tongue piece 23 that can be bent at right angles to the holding piece 22
is formed.

In order to attach this back plate 20, as shown in FIG. 10 and rotate the back plate 20 in the direction of the arrow. At this time, tongue piece 2
3 is not bent, so the tongue piece 23 is connected to the water level pipe 9.
However, the holding piece 22 comes into contact with the water level pipe 9, and the rotation of the back plate 20 is restricted. Here, the tongue piece 23 is bent forward at a right angle, and the holding piece 22 and the tongue piece 23 surround the water level pipe 9, so that the back plate 20 is prevented from lateral wobbling, and the back plate 20 is not attached. It will be done.

With the back plate 20 attached, the diagonal lines on the back plate 20 appear almost unchanged in the part of the water level tube 9 that does not contain water, but the part of the water level pipe 9 that contains water is hidden by the back plate due to the convex lens effect. The diagonal line 20 appears thick and changes in angle, making it possible to clearly see the water level.

As is clear from the above explanation, according to the present invention, the hanger part of the back plate is hooked on the upper end of the water level pipe, rotated, and locked with the holding piece, and then the tongue piece is bent and the water level pipe is turned. Since the back plate is held in place, the back plate can be easily attached without using any metal fittings. In addition, during repairs, it can be easily removed by simply folding the tongue piece of the back plate downward without removing the tube or water level pipe, and it is easy to replace.
