Description

[Detailed Description of the Invention] The present invention relates to a heat-retaining electric pot with a liquid level display device.

Conventional thermal electric pots can be heated and kept warm, making them convenient and extremely useful as they allow you to get hot water whenever you need it. Particularly recently, in order to improve the usability, liquid level display devices have been installed to display the amount of water remaining in the container.
As shown in FIGS. 1 and 2, a typical liquid level display device 5 has a vertically elongated window 3 at a suitable location on an outer case 2 in which a container 1 with an opening at the top is installed, and the upper and lower ends are It has a structure in which a rod-shaped transparent hollow tube 6 communicating with the container 1 via an int pipe 4 is disposed inside the outer case 2 so as to face the window 3. When water is poured into the container 1, the water level in the container 1 and the water level in the rod-shaped transparent hollow tube 6 match.
The water level inside the container 1 can be visually observed from the outside through the window 3. However, when using a commercially available heat-retaining electric pot using a liquid level display device 5 having this structure, it is very difficult to see the water level.
That is, one of the reasons why it is difficult to see is that the water is transparent, but since the transparent hollow tube 6 is located inside the outer case 2, that part becomes dark.
By the way, an attempt was made to place a piece of paper with a pattern on the back of the transparent hollow tube 6 and use the lens effect of the transparent hollow tube 6 to raise the water level in the area where the water level rose. Even with these considerations, there was a drawback in terms of visibility, as the transparent hollow tube was dark and it was still difficult to see the water level.

The present invention has been made to eliminate the above drawbacks, and includes a mirror plate at the L-shaped corner of the L-shaped joint pipe at the lower end of the transparent hollow tube of the liquid level display device, and a mirror plate near the transparent hollow tube. The purpose of the present invention is to provide a structure in which the water level in the container can be easily seen through the light from the pilot lamp by providing a pilot lamp facing the mirror plate so that the center of the transparent hollow tube forms a reflection angle.

An embodiment of the present invention will be described below with reference to the drawings.

The configuration of the embodiment is as shown in FIG. 3, but the 5 portions of the liquid level display device enclosed by the broken line in FIG. 2 are improved, and the parts other than those described below are the same as before.
The explanation will be omitted. The liquid level display device 5 is composed of the following: 7 is a mirror plate, and the mirror plate 7 is disposed diagonally leaning against the L-shaped corner portion of the L-shaped joint pipe 4 at the lower end of the transparent hollow tube 6.
Since the joint pipe 4 is made of rubber, the mirror plate 7 can be inserted and placed through the opening at one end. Reference numeral 8 denotes a pilot lamp, and this pilot lamp 8 is provided at the lower end back near the transparent hollow tube 6 via a mirror plate 7, and when the light from this pilot lamp 8 is reflected by the mirror plate 7, it is located at the center of the transparent hollow tube 6. Place the pilot lamp 8 in a position that illuminates approximately the center so that the angle of reflection is
is arranged. Further, although this pilot lamp 8 is not shown, due to the layout of the diagram, it is lit while the heat-retaining electric pot is energized. Reference numeral 9 denotes a reflecting plate, which is provided at a position facing the mirror plate 7 side of the pilot lamp 8 and has a mirror surface 10. Although the pilot lamp 8 and the reflector plate 9 are not shown, they are supported by a holder provided in the container 1. When this heat-retaining electric pot is in use, when water is poured into the container 1, water also enters the transparent hollow tube 6 at the same water level, and the pilot lamp 8 lights up while the electricity is on, so this light is a joint. The light that illuminates the mirror plate 7 disposed inside the pipe 5 and is reflected by the mirror surface 10 illuminates the inside of the transparent hollow tube 6, so that a so-called liquid level display section is illuminated with a lamp. Further, by providing the reflective plate 10 on the side opposite to the mirror plate 9 side of the pilot lamp 8, the inside of the transparent hollow tube 6 becomes even brighter. If paper with a pattern is placed on the back side of the transparent hollow tube 6 as in the past, the interior of the transparent hollow tube 6 will be bright and the lens effect will make it stand out even more.

According to the present invention, a mirror plate is provided at the L-shaped corner of the L-shaped joint pipe at the lower end of the transparent hollow tube of the liquid level display device, and the center of the transparent hollow tube is placed near the transparent hollow tube through the mirror plate. By providing a pilot lamp facing the mirror plate so that the angle of reflection is 1, the water level in the container is bright and easy to see, making it easy to recognize.
