Is preferably formed.
[0008]
According to the present invention, when the container body is heated, the temperature of the container body changes, and the color of the color changing filter changes sharply according to the temperature change. Thereby, the temperature change of the container body can be easily recognized by the color change of the color change filter.
[0009]
Further, the container body may be heated by induction heating. As described above, in the case of heating by induction heating, since the fire is invisible and the user is likely to be careless, the effect is large in that the temperature change of the container body can be easily recognized even if the fire is not visible.
[0010]
Further, the color changing member may be a material indicating one or a combination of one or more selected from a group of characters, graphics, and symbols by a temperature indicating material whose color changes according to temperature. . As a result, the user's attention can be paid to a picture or a character expressed by the discoloration.
[0011]
[Embodiment of the invention]
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted.
[0012]
First, the configuration of the cooking vessel for heating according to the present invention will be described with reference to the drawings. This embodiment is a case where the present invention is applied to a cooking container for induction heating (or a kitchen container) for heating by induction heating as a cooking container for heating. FIG. 2 is a perspective view showing an external configuration of the cooking container for induction heating. FIG. 3 is a partial sectional view of a cooking container for induction heating.
[0013]
As shown in FIGS. 2 and 3, the induction heating cooking container 30 includes a container main body 32 to be heated, a container main body 32, and a handle 34 provided on a side of the container main body 32. The container body 32 has a bottom plate 36 having a predetermined diameter, and a side wall 38 formed to extend upward so that the outer periphery of the bottom plate 36 is concentrically curved. The handle 34 is attached to one side of the side wall 38.
[0014]
A color changing member, for example, a color changing film 40, whose color (hue) changes according to a change in temperature, is attached to an outer surface, for example, an outer surface of the container body 32. The color change film 40 can realize color change by a thermochromic material that changes color when heated above a certain temperature, for example. Examples of the temperature indicating material include a temperature indicating pigment and a temperature indicating ink.
[0015]
For example, by forming the discoloration film 40 with a temperature indicating material, the color changes to various colors, and the expression before and after the change by heating becomes completely different, so that it is possible to easily recognize that the temperature has changed. .
[0016]
In addition, the main body 32 is easily heated to a certain temperature or more by expressing the discolored film 40 with a temperature indicating material such as a temperature indicating ink such as a stylized picture or character that can draw the user's attention. Then, the stylized pictures and characters are clearly expressed by the discoloration. Thereby, the temperature change can be easily recognized. The material represented by the temperature indicating material may be one or a combination of two or more selected from a group of characters, figures, and symbols.
[0017]
As described above, according to the cooking vessel for heating according to the present invention, the user can pay attention to the pictures, characters, and the like expressed by the discoloration. Thereby, the safety in using the cooking vessel for heating can be improved.
[0018]
Further, a coating layer 41 made of a transparent heat-resistant paint is formed on the outer surface of the color changing film 40 so as to cover the color changing film 40. For example, the discoloration film 40 may be attached to the outer surface of the outer surface of the container body 32 by water transfer, and the outer surface may be coated with a transparent heat-resistant paint or the like. Thereby, the discoloration film 40 can be prevented from being deformed by water or heat.
[0019]
Although the preferred embodiment of the present invention has been described with reference to the accompanying drawings, the present invention is not limited to such an example. It will be apparent to those skilled in the art that various changes or modifications can be made within the scope of the technical idea described in the claims of the utility model registration.
