Description

Vehicle heater {HEATER FOR VEHICLE}

The present invention relates to a vehicle heater, and more particularly, to a vehicle heater capable of varying set temperatures for each region.

Since the cooling water is not sufficiently heated at the beginning of startup in the winter season, the interior of the vehicle cannot be quickly heated, so a radiant heat heater can be installed in the interior of the vehicle to improve heating comfort by directly emitting radiant heat to the occupants using radiant heat. have.

These radiant heat heaters for vehicles are installed on the lower side of the dashboard, the steering column on the driver's seat side, the glove box on the passenger seat side, the backrest of the front seat, etc., and emit radiant heat directly toward the legs of the occupant, thereby providing rapid heating. is making it possible to

For example, in a conventional radiant heater, a radiant heater device is installed on the underside of a steering column connected to a steering wheel of a driver's seat of a vehicle to emit radiant heat toward the legs of a seated occupant. Such a radiant heater device is configured in a form in which a heat dissipation part, a heating wire pad composed of a heating wire, and a terminal are formed on a substrate.

However, since the conventional radiant heater can only set the same temperature in the entire area, there is a problem in that it cannot be controlled to a desired temperature for each location. That is, when there are a plurality of occupants, the desired temperature is different for each person, but it is not possible to individually set the desired temperature, which is inconvenient in use.
