Abstract

It consists of a low-voltage current motor 1 fitted with blades 2, with an oscillation blocking and unblocking mechanism 3, with a low-voltage current electric heating resistor 4 which can be disconnected from the assembly 5 and is mounted under a protective grille 6, a switch 7, which may be a rheostat or thermostat, a cigar lighter connection lead 8 which can be released from the connector 9 if the apparatus becomes detached from its mounting 10. According to one variant, the vehicles can be fitted in the workshop, or optionally by a low-voltage current individual electric heating system, comprising a casing containing an electrical resistor, and a fan which may be that of the vehicle, then of a switch which may be a rheostat or thermostat.

Description

 The present invention relates to an electric heating fan with low voltage current, mainly for motor vehicles.

 The heating device according to the invention makes it possible to diffuse heat, mainly on vehicle windows, for defrosting or demisting.

 According to the device, gasoline is saved, so no pollution because there is no need to run the engine, and in addition it prevents theft of the vehicle because the doors will be locked.

 On the one hand, there is known a heating panel consisting of a substrate carrying coatings of conductive material.

 On the other hand, an invention is known concerning a device prohibiting fogging or icing of transparent bodies, such as the windshields of a parked vehicle and constituted by a flat structure, and supports for fixing the latter. in a position substantially parallel to the surface of the body.

 ruis we know the classic device by the heat transmitted by the engine of the vehicle.

 The device according to the invention consists, as regards the heating fan, of a low voltage motor equipped with a propeller, of an oscillation blocking and unblocking, of an electric heating resistance with low voltage current which can be manufactured in various metals and alloys and of varied shape, being able to be: # disconnected, for the use of the ventilator in blower of fresh air, and assembled under the grid of protection of the ventilator with a suitable material, of inter breaker, which can be a rheostat or thermostat, e ## dIun connection to the power supply of the vehicle, as well as a fixing, which can be a suction cup, a clamp, or other mechanical or magnetic system.

 For the operation of the heated fan, simply plug it into the cigarette lighter using the appropriate socket and activate the switch, making sure that the cables are connected.

 Connection can be provided without a switch.

 If the vehicle does not have a cigarette lighter, it is sufficient to connect to a good power supply line.

 There is commercially available a cigarette lighter to be fitted on unequipped vehicles.

 For safety, the power cables disengage if the fan detaches from the support.

 Other safety systems can be mounted on the heated fan assembly.

 To allow air to be swept, either hot or fresh, the fan is fitted with an orientation lock and unlock.

 To use the fan for fresh air, simply disconnect the heating system.

 The heated fan can be designed in a personalized aesthetic.

 According to a variant, the vehicles can be equipped at the factory or as an option by an individual electric heating system with low voltage current, placed hidden or visible on the vehicles, either as main or additional heating, comprising an electric resistance placed in front or behind or laterally of the existing or added fan.

 The electrical resistance can be of design, shape, of various metals and alloys, and placed in a box or oven ~ rack or other location to store heat.

 By unplugging the heater, the fan may blow fresh air.

 Figure I shows, on the bias, the device according to the invention.

 The device shown in Figure I consists of a Partdtun low voltage motor (I) equipped with a hrlice (2), a blocking and unblocking of oscillation (3), an electric heating resistance current low voltage (4) which can be disconnected at assembly (5) and mounted under a protective grid (6), with a switch (7) which can be a rheostat or thermostat regulating the stop and start, as well as the current or heating power.

The current, plugged into the cigarette lighter (8), can, for safety, disengage at the fitting (Y) if the device detaches from its fixing (IO)
For the operation of the heated fan, simply connect the power supply to the cigarette lighter, make sure that the cables are assembled at the fittings (5) and (9) and activate the switch (7)
To operate the fan for fresh air, simply disconnect the resistance at the fitting (5).

Claims (2)

 I) Heating device, with low voltage current, and mounted on a fan assembly, to allow the diffusion of heat, mainly on vehicle windows for defrosting or demisting, characterized in that it comprises a low voltage motor ( I) equipped with a propeller (2), a blocking and unblocking of oscillation (3), an electric heating resistor with low voltage current (4), which can be dislodged at the fitting (5), and mounted under the grille (6), a switch (7), regulating the stop and the running, and a connection to the cigarette lighter (8) or another connection which can be disengaged at the fitting (9), and a fixing (IO) which can be a clamp, a suction cup, or other mechanical and magnetic system.  2) Device according to claim I characterized in that a switch (7) regulating the stop and the run, can be a rheostat or thermostat, making it possible to adjust the intensity of the current or the heating power.
