Description

[Detailed Description of the Invention] This invention relates to the improvement of electric appliances such as electric shavers and portable face washers, and particularly relates to electric appliances whose power source is charged by a solar cell.

This invention also allows the mirror to be removed from the main body by attaching the mirror to a plate-shaped solar cell part that is detachably attached to a part of the peripheral wall of the main body. When using this device, it is mounted so that it can rotate freely around one side of the solar cell section, and is arranged so that the reflective surface of the mirror and the light-receiving surface of the solar cell section are facing each other. Depending on the rotational opening angle of the mirror viewed by the user with respect to the solar cell section, reflected light from the mirror can also be supplied to the solar cells, thereby increasing power generation efficiency.

Hereinafter, embodiments of this invention will be explained with reference to the drawings using an example of an electric shaver.

In the drawings, reference numeral 1 denotes a main body case, in which a motor 2, a blade part 3, and a switch 4 for driving the motor 2 are provided in the head part, and a rechargeable battery 5 as a power source for driving the motor is housed in the body part. There is.

This rechargeable battery 5 is connected from both ends to connection terminals 8 and 9 via a lead wire 6 and a backflow prevention diode 7, and has a recessed step 10 with one end open on a part of the peripheral wall of the main body case 1. Provided, this recessed step 10
Gutter grooves 11, 11 are provided on both side walls, and the solar cell section 12 is slid therein. When the solar cell section 12 is housed in the recess, the supply terminals 13 and 14 of the solar cell section 12 come into contact with the connection terminals 8 and 9, and in this case, the light receiving surface 12a of the solar cell section 12 is exposed to light. For example, power is generated and the rechargeable battery 5 is charged.

A mirror 15 is attached to the solar cell section 12 so as to be rotatable around one side thereof.
reflective surface 15a of and light receiving surface 12a of solar cell section 12
Since the light receiving surface 12a faces the light receiving surface 12a, the amount of light received is increased by the direct light beam and the reflected light beam K from the mirror 15, and the power generation efficiency is increased. For this purpose, the rotation opening angle θ between the mirror 15 and the solar cell section 12 must be adjusted appropriately.

This mirror 15 can be reversely rotated as shown by the broken line in the drawing, and the mirror 15 can be folded in the opposite direction to the solar cell part 12 and stored in the recessed part 10. Of course, as shown by the solid line in the drawing Even in the open state, it can be stored in the recessed step 10.

The reflective surface 15a of the mirror 15 may be made of glass, but in order to be thin and lightweight, it may be made of aluminum vapor deposition or mirror-polished stainless steel plate.

As described above, according to this invention, the following effects can be obtained. Generally, electric devices that require a mirror, such as electric razors and face wash machines, have their mirrors stored directly in the case for storage and storage.
Although this is preferable from the point of view of handling, a single mirror structure is likely to cause cracks and distortions due to the low mechanical strength of the mirror itself.

Moreover, in this invention, the mirror 15 is attached to the plate-shaped solar cell section 12, and this is attached as one body to the main body case 1 in a detachable manner.
Even during transportation, mechanical strength can be improved and individual performance can be demonstrated.

In particular, according to this invention, when the solar cell section 12 is removed from the main body case 1, the solar cell section 12 side acts as a stand for the mirror 15, eliminating the inconvenience of the user holding the mirror in his hand. Moreover, if the mirror 15 is kept open and stored in the recessed step 10 of the main body case 1, the power generation efficiency can be increased by utilizing the reflected light from the mirror 15.
