Description

[Detailed description of the invention] (Industrial application field) The present invention calculates the amount of liquid in the container installed inside the exterior body.
This invention relates to a liquid level display device for a pot that can be easily checked from the outside.

(Prior Art) First, as an example of this type of pot, the structure of a water pot having water boiling and heat retention functions will be described with reference to FIG. In FIG. 3, 1 is a container for storing liquid, 2 is an exterior body formed into a hollow cylindrical shape by a metal plate and has a bottom plate 3 attached to its lower end, and 4 is an exterior body 2 that houses the upper end of the container 1. 5 is a panel provided on the outer surface of the exterior body 2 and has a vertically elongated display window 6; 7 is an elbow joint 8 which is erected on the outside of the container 1 with elbow joints 8; , 8, a transparent liquid level display tube communicating with the inside of the container 1; 9, an inner lid for sealing the opening of the container 1; 10, an air supply passage containing a check valve 11 for preventing water leakage; 12; is a pumping pipe supported on the inner lid 9, 1
3 is a spouting pipe similarly supported on the inner lid 9, 14 is a leakage prevention valve installed in the communication passage between the two pipes 12 and 13, 15 is an upper lid pivotably mounted on the upper ring 4 so as to be openable and detachable, and 16 is a An air pump 19 is a heater located inside the upper lid 15 and consists of a bellows 17 and a push button 18 for compressing the bellows 17;
Air is sent into the container 1 through the air supply passage 10 of the inner lid 9, and the liquid in the container 1 is pumped up through the pipe 12,
It has a structure in which it is pumped outward through a spouting pipe 13. In such a jar pot, the liquid level display tube 7 is placed opposite to the inside of the display window 6, and the water level of the liquid level display tube 7 can be visually checked from the outside.
The amount of liquid in the container 1 can be checked.

By the way, in this type of pot, in order to make the water level in the liquid level display tube 7 easier to see, various measures have been taken in the past.For example, as shown in FIG. Display sticker 20
is attached to the back side of the liquid level display tube 7. In this case, the liquid level display tube 7 is connected from the display window 6.
When looking at the diagonal striped pattern of the liquid level display sticker 20 through the liquid level display tube 7, the diagonal striped pattern appears different at the water level a as shown in Figure 5 due to the lens action of the liquid in the liquid level display tube 7. With this, the water level, that is, the amount of liquid in the container 1 can be easily confirmed.

(Problem to be solved by the invention) However, in the conventional structure, when attaching the elongated liquid level display sticker 20 to the liquid level display tube 7, there is no part of the liquid level display tube 7 that can be used as a guide for positioning. For this reason, it is extremely difficult to affix the liquid level display sticker 20 properly and in a straight line, and requires skill. The positional relationship between the two parts must be taken into consideration, resulting in poor assembly work efficiency and high assembly costs.

However, the present invention provides a liquid level display device that is easy to assemble.

(Means for Solving the Problems) The content of the present invention will be explained below with reference to FIGS. 1 and 2, and also FIG. 3, which correspond to embodiments.

An exterior body 2 provided with a panel 5 having a vertically elongated display window 6, a container 1 installed inside the exterior body 2 and containing a liquid, and a container 1 that is in communication with the container 1 and erected on the outside of the container 1. In the pot liquid level display device, the liquid level display device is equipped with a transparent liquid level display tube 7, and the liquid level display tube 7 is positioned opposite to the inside of the display window 6. It is bent into a substantially semicircular shape to form a vertically elongated groove 21, and the liquid quantity display tube 7 is disposed within this groove 21. Then, the inner surface 21' of the groove portion 21
By directly printing a diagonal striped pattern, a mesh pattern, a scale, etc., or pasting a liquid level display sticker printed with these, the inner surface 21' is used as a liquid level display surface.

(Function) In the above configuration, if a striped pattern or the like is directly printed on the inner surface 21' of the groove 21, the work of pasting a liquid level display sticker can be omitted, and the printing can be done easily.
This can be done simultaneously with the conventional decorative printing on the outer peripheral surface of the exterior body 1. On the other hand, the inner surface 2 of the groove 21
1', the pasting work itself cannot be omitted, but the work can be done using the side edge 21a of the groove 21 as a guide for positioning, and the liquid level can be adjusted along the side edge 21a. By pasting the display sticker, it can be easily and straightly pasted, and no special skill is required. Therefore, the workability is significantly improved compared to the case where a liquid level display sticker is attached to the liquid level display tube 7.

Further, when arranging the liquid volume display tube 7, there is no need to consider the positional relationship as in the conventional case.

(Embodiment) The embodiment of the present invention shown in FIGS. 1 and 2 will be described in detail below with reference to FIG. 3.

The exterior body 2 has a vertically long groove 21 formed by bending a part of the outer surface inward into a substantially semicircular shape.
The display window 6 of the panel 5 and the inner surface 21' of the groove 21 are positioned opposite to each other. The liquid level display tube 7 is disposed within the groove 21 and is located opposite to the inside of the display window 6. In the figure, 22 indicates a transparent protective member provided on the display window 6.

The outer peripheral surface of the exterior body 2 is usually printed with a decorative color pattern, and at this time, for example, a diagonal striped pattern is simultaneously printed on the inner surface 21' of the groove 21 to make the inner surface 21'. Use as liquid level display surface. The pattern on the liquid level display surface varies from the display window 6 to the liquid level display tube 7.
It can be seen through the liquid level display tube 7, and it appears to change as shown in Figure 5 depending on the presence or absence of liquid in the liquid level display tube 7, and as a result, the water level in the liquid level display tube 7 and, by extension, the container 1.
This means that you can easily check the amount of liquid inside.

In an embodiment having such a configuration, a liquid amount display sticker is not required, and the work of attaching the sticker itself can be omitted.

In addition, in the present invention, the inner surface 21' of the groove portion 21
This also includes a device in which a conventional liquid amount display sticker is pasted on the inner surface 21' to serve as a liquid amount display surface.
In this case, it is necessary to paste the sticker as in the past, but if you use the side edge 21' of the groove 21 as a guide for positioning, you can paste the liquid level display sticker along the side edge 21'. The liquid level display sticker can be applied straight and easily, and the workability is significantly improved without requiring special skill. Since the liquid level display tube 7 does not have a liquid level display sticker pasted on it, there is no need to consider the positional relationship between the display window 6 and the liquid level display sticker when installing it, and the overall assembly work efficiency is significantly improved. I can do it.

Further, the present invention is not limited to the jar pot shown in the third figure, but for example, the lower end of the liquid volume display tube 7 is connected to the inner bottom of the container 1, and the upper end is connected to the spouting tube, so that the display tube 7 is connected to the liquid pouring path. Of course, it can also be implemented in a pot having a structure that serves as a part of the same.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications such as patterns and scales on the liquid level display surface without departing from the gist.

(Effects of the invention) As described above, in the present invention, a part of the exterior body is bent inward into a substantially semicircular shape to form a vertically long groove, and the liquid level display tube is placed within this groove. However, by using the inner surface of the groove as a liquid level display surface, it is possible to significantly improve assembly workability and reduce assembly costs, which is an extremely useful idea in practice.
