DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a cordless dryer according to the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the cordless dryer. In this figure, a loading part 3 inside a grip part 2 of a dryer body 1 is shown.
The storage battery 4 composed of a nickel-cadmium battery or the like can be detachably loaded from below. This storage battery 4
Can be charged by attaching it to the fitting portion 6 of the battery charger 5 as shown in FIG. The output of the storage battery 4 is set to, for example, 12V. 7a, 7
Reference numerals b, 8a, and 8b denote electrodes of the storage battery 4. If another battery 4 is charged in advance by the charger 5, the dryer can be continuously used by replacing the battery 4. A blower fan 9 is attached to the upper part of the dryer main body 1 above the grip portion 2. This blower fan 9
Are driven by receiving electric power from the storage battery 4. On one side of the dryer main body 1, a cylindrical protrusion 12 serving as an air passage 11 for housing the electric heating unit 10 is provided so as to protrude therefrom.
The tip of the cylindrical projection 12 is a hot air outlet 13. The wind blown from the blower fan 9 is supplied to the electric heating unit 1.
0, and hot air is blown out from the outlet 13.

Next, the configuration of the electric heating unit 10 housed inside the cylindrical projection 12 will be described. As shown in FIGS. 4 and 5, the electric heating unit 10 has a configuration in which a thin-film planar heating element 16 is applied to an inner wall surface of a substantially cylindrical adherend 15 in which a slit 14 is cut out in a longitudinal direction. ing. The adherend 15 is
It is made of ceramic, glass, metal, etc. The positive and negative electrodes 17a and 17b of the thin film planar heating element 16 are shown in FIG.
Are connected to the positive and negative electrodes 7a and 7b of the storage battery 4 via the switch 18 as shown in FIG. The electric heating section 10 is attached to the cylindrical projection 12 of the dryer main body 1 by a mounting bracket 19.
It is fixed to the inner wall.

The thin-film planar heating element 16 is formed by mixing, for example, a mixed liquid of tin oxide and other impurities, or by mixing a mixed liquid of indium and other impurities. The thin film sheet heating element 16 is heated to 250 degrees Celsius in about 15 seconds as shown in FIG. The thin film heating element 16 may be attached to the outer wall surface of the adherend 15.
Further, the adherend is not limited to a cylindrical shape, and may be a cross-shaped plate-like structure.

In the cordless dryer thus configured, when the switch 18 is turned on, the blower fan 9 rotates and the thin-film sheet heating element 16 generates heat.
Is heated when passing through the thin-film planar heating element 16, so that hot air is blown from the outlet 16.

Next, another embodiment will be described. In this embodiment, no electric heating portion is provided inside the cylindrical projecting portion 12 of the dryer main body 1, and the thin film planar heating element 20 is attached to each blade 9 a of the blower fan 9. Storage battery 4
In order to energize the thin-film planar heating element 20, positive and negative conducting electrodes 21 and 22 are provided coaxially on the shaft 10 of the fan 9, and these electrodes 21 and 22 are connected to the thin-film planar heating element 20. It is connected to the. In addition, the positive and negative conducting electrodes 2
Brushes 23 and 24 come into contact with the brushes 1 and 22, respectively. These brushes 23 and 24 are connected to the storage battery 4 via the switch 18.

In the cordless dryer configured as described above, when the switch 18 is turned on, the blower fan 9 rotates and the thin film sheet heating element 20 attached to the blade 9a of the fan 9 is energized to turn on the surface. The heating element 20 generates heat. Thereby, the hot air heated by the planar heating element 20 is blown by the fan 9 and blown out from the blowout port 13.

Next, another embodiment will be described with reference to FIG. In this embodiment, the blower fan is configured as a spiral fan 26 having a spiral blade 27 protruding from the outer periphery. The thin-film sheet heating element 31 is attached to the inner wall of the outer cylinder 30. This thin film planar heating element 3
1 is supplied with power from a storage battery 4 loaded in the grip portion 2 via a switch 18.

In the cordless dryer configured as described above, when the switch 18 is turned on, the thin film planar heating element 31 attached to the inner wall of the outer cylinder 30 generates heat, and the spiral fan 26 rotates to generate hot air. Is blown out from the outlet 32 of the outer cylinder 30. The thin-film planar heating element may be attached to the blade 27 of the spiral fan 26 or the inner cylinder 28 of the spiral fan 26.

[0014]

As described above, according to the present invention, since the electric heating section is constituted by the thin-film sheet heating element, it can be driven by a storage battery and can be made cordless.
Thereby, there is an advantage that convenience can be improved because the device can be carried. Further, in the present invention, there is an advantage that the configuration is simplified and the dryer can be reduced in size by attaching the thin-film planar heating element to the blade of the blower fan. The thin-film sheet heating element does not require a thermostat because the heating temperature can be kept constant by the coating area and coating thickness, but a temperature controller can be interposed when used in low or high temperature areas. . The use of ceramics, glass, and metal as the adherend increases the degree of freedom in design.
