Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to an electric heater such as an electric blanket or an electric carpet, in which a heater that generates heat when energized is insulated and disposed in the main body.

<Prior art> Conventional electric heaters such as electric blankets and electric carpets are constructed by, for example, nichrome wire heaters covered with vinyl chloride, silicone rubber, etc., arranged in a main body made of fibers, soft plastic foam, etc. Electric heaters configured in this way get dirty when used at home, so they need to be washed at appropriate times, but in this case, washing should be done in a way other than dry cleaning. Despite the fact that manufacturers have provided some sort of warning to users to avoid dry cleaning, users often wash their clothes in dry cleaning. The insulating coatings of nichrome wire heaters and the like were destroyed by the perchloroethylene used during dry cleaning, making them dangerous to use and often resulting in complaints to manufacturers.

However, conventional electric heaters have the disadvantage that it is not easy to determine whether the above-mentioned cause is due to dry cleaning.

<Purpose of the invention> The object of the invention is to obtain an electric heater that eliminates the above-mentioned drawbacks.

<Embodiment of the invention> An embodiment of the electric heater of the invention will be described below with reference to the drawings.

The electric heater of the present invention has a heater that generates heat when energized, such as a nichrome wire heater, coated with vinyl chloride or silicone rubber, etc., and is arranged in a main body 1 made of fiber or soft plastic foam, etc. A detection body 2 is provided at a position to detect whether or not dry cleaning has been performed, and the detection body 2 detects whether or not dry cleaning has been performed to determine whether the cause of the malfunction, etc. is due to dry cleaning. It is structured as follows.

In the above configuration, the detection body 2 is coated with a cloth 2a made of natural fibers or synthetic fibers, or coated with a paint made by dissolving an acrylic styrene modified product in toluene, such as Telesan Resin EXP652 (product name of Teikoku Kagaku Sangyo Co., Ltd.) 2b. After being impregnated and dried, it is colored with ink 2c of an appropriate tone to display a predetermined (some kind of) indication.

In the electric heater configured as described above, when the main body becomes dirty and the user performs dry cleaning for washing, the detection body 2 at a predetermined position of the main body 1 may be contaminated with acrylic styrene. The paint 2b, which was dissolved in toluene, was dissolved in perchloroethylene used for dry cleaning, and the coloring of the ink 2c disappeared, and it was detected that dry cleaning was performed, and the cause of the malfunction, etc. was due to dry cleaning. This is to determine that.

<Effects of the invention> Since the electric heater of the invention has the above-mentioned configuration, it is possible to easily determine whether the cause of a malfunction, etc. is due to dry cleaning. These services can be performed extremely quickly and reliably.
