Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, in general, the battery unit 10 supplies a voltage of 12 V to 13.8 V to the cigarette lighter unit 20, wherein the cigarette lighter unit 20 has a power amount of 180 W to 200 W ( POWER). The cigarette lighter unit 20 is connected to the first switch 30 and the second switch 35 by a connecting plug (not shown), and the heater unit 40 generating heat to the first switch 30. And a fan driver 50 for discharging the heat generated by the heater unit 40 to the outside, and a timer 72 and a relay switch unit for controlling the operation time of the heater unit 40 and the fan driver 50. An operation control unit 70 composed of 76 is connected, and a voltage boosting unit 90 for boosting the voltage applied from the cigarette lighter unit 20 to a high voltage is connected to the second switch 35, and the voltage boosting unit 90. Ion generators 60 that generate negative ions by the high voltage applied through are connected to each.

As can be seen from the above description, the present invention connects a connection plug (not shown) to the cigarette lighter unit 20 that is supplied with power from the battery unit 10 to the heater unit 40 and the ion generating unit 60. Because it operates selectively, it is necessary to use a very limited power source to generate heat to quickly and sufficiently warm the interior of the vehicle.

That is, since the power P of 180W to 200W of the cigarette lighter unit 20 and the voltage of 12V to 13.8V supplied from the battery unit 10 are limited, it is possible to use the limited capacity power supply. Minimize the resistance to generate enough heat to warm the car's interior. Must). Because power (P) = voltage (V ² ) / resistance (R), the resistance (R) is about 0.9 ( This is because it cannot exceed).

However, since the magnitude of the resistance is proportional to the length and inversely proportional to the thickness (cross-sectional area), the length of the heating wire should be as short as possible and the thickness should be as thick as possible in order to reduce the resistance value. Therefore, in the present invention, by connecting several heating wires in a parallel manner, while minimizing the resistance while making the heating wire long enough (1 Will be enabled).

When the present invention is described in more detail with reference to the above theory, a first switch 30 for operating the heater unit 40 is connected to a connection plug (not shown) connected to the cigarette lighter unit 20. The switch 30 includes a fan driver 50 operated by a power source applied through the cigarette lighter unit 20 and a heater unit 40 including a plurality of thick and short heating wires 42 formed in parallel to generate high temperature heat. Are connected to each other, and when the first switch 30 is switched on, the hot wire 42 of the heater unit 40 immediately generates high-temperature heat sufficient to warm the room, and at the same time, the fan driving unit 50 is driven. Thus, the heat generated from the heater 40 is discharged into the vehicle compartment to distribute the heat evenly.

An operation control unit 70 including a timer 72 and a relay switch unit 76 is connected between the first switch 30, the heater unit 40, and the fan driving unit 50, and the timer 72 is set. After a certain time has elapsed, the relay of the relay switch unit 76 is driven and the relay switch 76 is turned off, so that the heater unit 40 and the fan driving unit 50 stop operation. This prevents the temperature of the interior of the vehicle raised by the heater unit 40 from being warmed more than necessary, while the vehicle warms up warmly and the energy of the driver forgoing the operation timing of the heater control switch 46 for a while. This is to prevent waste.

And, by connecting the heater control switch 46 to the heater unit 40 for generating a high temperature heat to select and operate according to the season, only the fan drive unit 50 can be operated in the summer.

In addition, the second light switch 35 for operating the ion generator 60 is connected to the cigarette lighter 20 by a connection plug (not shown), and a reverse current flow is connected to the second switch 35. The prevention unit 62 is connected to prevent the applied power from flowing in the reverse direction, and the reverse current flow prevention unit 62 is connected to the constant voltage holding unit 64 to maintain the applied power at a constant voltage. The oscillation unit 68 is brought into contact with the constant voltage holding unit 64 to oscillate the voltage applied from the constant voltage holding unit 64, thereby applying the AC voltage generated by the oscillation to the transformer unit 66. The transformer 66 removes the erroneous signal while transmitting at the same rate when an AC voltage is applied from the oscillator 68.

A high voltage boosting unit 90 is connected to the transformer unit 66 to boost the voltage to a high pressure of about 14,000 V, and the boosted high voltage is applied to the ion generating unit 60 and the high voltage applied to the ion generating unit 60. The anion is generated through the negative ion generating pin 68.

As described above, the present invention comprises a heater unit for generating heat and an ion generator for purifying air integrally, and the heater unit is configured in parallel with the heating wire for generating heat, thereby effectively applying high heat with a low power supply. Can be generated.
