Abstract
The invention discloses an electric hot wind device, and in particular relates to an electric hair drier. The prior cassette mechanism structure is not suitable for manufacturing an electric hair drier with small volume and large power. A heating body of the electric hair drier is in a spiral spring shape of which the cross section is in an elliptical shape made by winding electrically heated wires. The heating body is wound on the outer edge of a supporting frame, and the long axis direction of the cross section of the heating body is pointed to the interior of the wound cassette mechanism. Because the heating body is in the spiral spring shape of which the cross section is in the elliptical shape made by winding the electrically heated wires, the power of the electric hair drier can be adjusted by changing the proportion of the elliptical long axis and the short axis of the cross section of the heating body in the spiral spring shape, and is not limited by the wind hole space. Alongwith the increase of the power and the lengthening of the elliptical long axis of the cross section of the heating body in the spiral spring shape, the heat radiation of the cassette mechanism is more uniform, the hour temperature deviation of the wind hole is smaller so as to ensure that the temperature distribution of the wind hole of the electric hair drier is more uniform, thereby reducing the deformation state of the electrically heated wires caused by non-uniform heat, and prolonging the service life of the electric hair drier.

Hair dryer, it comprises the shell with approximate tubular wind-tunnel and is arranged on fan in the described wind-tunnel, is used to the movement that drives the fan motor rotating, be used to generate heat, described movement comprises support and the heater on this support, it is characterized in that: described heater is oval-shaped coil spring shape for turning to cross section with heating wire, this heater is around the outer rim of described support, and the long axis direction of this heater cross section points to the inside of the movement that turns to.
The invention has the beneficial effects as follows:
1, because heater is oval-shaped coil spring shape for turning to cross section with heating wire, can adjust the power of hair dryer by the ratio that changes coil spring shape heater cross section transverse and minor axis, be not subjected to the restriction in wind-tunnel space.
2, along with the increase of power, the lengthening of coil spring shape heater cross section transverse makes the movement heat radiation more even, temperature deviation is littler during wind-tunnel, make the Temperature Distribution of hair dryer wind-tunnel mouth more even, thereby reduced heating wire owing to the irregular state that is out of shape of heat, prolonged the service life of hair dryer.

The specific embodiment
The hair dryer of one embodiment of the present of invention is now described according to Figure of description.Fig. 1 shows the structure according to the hair dryer of this embodiment, and it comprises: have the shell 2 of tubular wind-tunnel, fan 4 and be used to drive the motor 3 of fan 4, and the movement 1 that is used to generate heat.Movement 1 is supported on air outlet plate washer 10 inboards, and switch 9 is located on the handle 8, and process switch 9 starter motors 3 make fan 4 rotations and produce air-flow, and the heat that movement 1 produces is outside from air outlet plate washer 10 flow directions through the wind-tunnel of shell 2.
More detailed, direct or the indirect structure of having expressed movement 1 among Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, it comprises support 5 and the heater 11 (referring to Fig. 2,4) of shape on this support 5 in the shape of a spiral, and support 5 prevents fixedly that by the gear muscle in the wind-tunnel of shell 2 whole movement 1 from rotating or moving.Heater 11 is oval-shaped coil spring shape (shape of cross section is referring to Fig. 3) for turning to cross section with heating wire 6, this heater 11 is around the outer rim of support 5, and the long axis direction of these heater 11 cross sections points to the inside of the movement 1 that turns to, and best implementation is the center that the long axis direction of heater cross section points to the movement 1 that turns to.The main body of heater 11 is positioned at the inboard (referring to Fig. 5,6) of itself and support 5 contacts site, can occupy same space with support thus, makes whole movement 1 occupy the space of wind-tunnel in the less shell, is convenient to design the hair dryer of small-volume large-power.And being designed to its cross section, support 5 is radial, it shown in the figure " ten " word shape (referring to Fig. 5), offer the groove 7 (referring to Fig. 7) that is used for the heating wire location on the support 5, therefore with heater 11 on support 5 time, just after heating wire 6 being turned to spring, be hooked on (referring to Fig. 6) on the support 5, conserve space, the moving of all directions that can stop simultaneously heating wire 6, and be out of shape cause loosening after being used for supporting the electrothermal wire heating, all kinds of grooves 7 of support 5 can be finished by punching process, heating wire 6 by spiral filament forming machine directly on support 5, also can be by manual coiling.The cross section of heating wire 6 is circle, ellipse, triangle or polygon.Heater 11 is identical oval-shaped coil spring shape for turning to cross section with heating wire at length direction; Perhaps heater is the oval-shaped coil spring shape of size interval for turning to cross section with heating wire at length direction, and at this moment, the cross section of the size interval of heater can be arranged in order at length direction, also can lack of alignment.According to the size of the wind-tunnel of hair dryer watt level and shell 2, can suitably adjust the ratio of long axis of ellipse and minor axis.
