JPH10197363A - Display device for high temperature of apparatus - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a display device by which the high temperature of an apparatus can be displayed without using a power supply by a method wherein a polymer material which is changed to be transparent in a high-temperature state is used. SOLUTION: A polymer material 1 and an indication material 2 are attached to an apparatus in such a way that the indication material 2 is situated on the inner side. Then, since the polymer material 1 is transparent while the apparatus is at a high temperature, a display such as 'Be careful about high temperature!' or the like by the indication material 2 attached on the inner side is visible. Consequently, at a point of time when a user cannot see the display, i.e., when the temperature of the apparatus becomes room temperature in such a way that the polymer material 1 becomes opaque and that the indication material 2 is hidden, it is safe to execute a cleaning operation or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for displaying that a device is in a high temperature state.

[0002]

2. Description of the Related Art For example, an iron is "hot" during use,
There are temperature displays such as "medium temperature" and "low temperature", and the user can iron according to the temperature display. However, when the user has finished using the device and unplugged the device from the outlet, all the indications have disappeared. Therefore, in this state, it is not possible to know the temperature state of the iron, and for example, a burn may occur when the base is touched. As in this example, when the power supply is cut off after the use of the device, the device itself does not display the current temperature of the device by itself.

[0003]

As described above, the conventional device has a problem that the current temperature of the device cannot be displayed when the power supply is cut off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention described in claim 1 uses a polymer material that is transparent in a high temperature state, and recognizes a color or character attached below in a high temperature state to recognize a high temperature state. It is used as a high-temperature display device for equipment.

According to a second aspect of the present invention, an indicator material is provided on one side of a polymer material so that a display of the indicator material can be visually recognized in a high-temperature state, thereby providing a high-temperature display device for a device that recognizes the high-temperature state. .

According to a third aspect of the present invention, there is provided a high-temperature display device for an apparatus in which a space is provided between a polymer material and an indicator material so that the thickness of the polymer material used can be reduced.

According to a fourth aspect of the present invention, there is provided a high-temperature display device for an apparatus in which both surfaces of a polymer material are covered with transparent plates so that the polymer material is not damaged.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a conceptual diagram showing the configuration of the present embodiment. Reference numeral 1 denotes a polymer material. In this embodiment, a polymer material (Linklon manufactured by Mitsubishi Chemical Corporation) obtained by subjecting a polyolefin-based material such as high-density polyethylene / polypropylene to silane crosslinking is used. The polymer material 1 has such a property that the transparency increases with an increase in temperature and becomes opaque at room temperature. On the back surface of the polymer material 1, an indicating material 2
Has been arranged. The instruction material 2 does not need to be particularly limited in material, but is displayed in characters such as "Caution for high temperature".

The operation of the embodiment will be described below. If the polymer material 1 and the indicator material 2 are attached to the device so that the indicator material 2 is located inside, the temperature of the device can be easily recognized. That is, since the polymer material 1 is transparent while the device is at a high temperature, the indication such as "Caution for high temperature" of the instruction material 2 attached inside can be seen. Therefore, when the display disappears, that is, when the temperature of the device becomes room temperature, the polymer material 1 becomes opaque, and the indicating material 2 is hidden, the user performs a work such as rearrangement. Is what you can do.

In this embodiment, a dedicated component is used as the indicating material 2. However, it does not matter if a part of the apparatus is used as it is.

As described above, according to the present embodiment, while the temperature of the device is high, the indication of the indicating material 2 can be seen by utilizing the fact that the polymer material 1 becomes transparent, and the safety of the device can be improved. Can be easily confirmed.

At this time, as shown in FIG. 2, when the structure using the spacer 4 is adopted, the change in color can be clearly recognized even when the thickness of the polymer material 1 is reduced.
That is, if the indicator material 2 is arranged with the spacer 4 interposed therebetween, the space 3 is located between the polymer material 1 and the indicator material 2.
Can be provided.

As shown in FIG. 4, when the polymer material 1 is sandwiched between transparent plates 5, the polymer material 1
Are not rubbed and damaged, and the transparent plate 5 also functions as a spacer between the polymer material 1 and the indicator material 2, so that a high-temperature display device of a compact device can be realized.

According to the first aspect of the present invention, a polymer material that changes from an opaque state to a transparent state with respect to a temperature change from room temperature to a high temperature uses a polymer material without requiring electric energy. It is possible to realize a high temperature display device of a device capable of displaying a high temperature state.

According to a second aspect of the present invention, a high-temperature display device of an apparatus capable of visually recognizing a display of an indicating material in a high-temperature state and recognizing the high-temperature state is realized by using a structure in which the polymer material has an indicating material on one side. Is what you do.

The third aspect of the present invention realizes a high-temperature display device of an apparatus which can reduce the thickness of a polymer material to be used by providing a space between a polymer material and an indicator material. .
