Technical Field
The present invention relates to a washing liquid heating apparatus, and more particularly, to a washing liquid heating apparatus that heats washing liquid flowing along a heating unit and sprays the washing liquid at or above a predetermined temperature through a washing liquid nozzle.
Background
One important factor for safe driving of a vehicle is ensuring a forward view. Therefore, the conventional vehicle is equipped with a wiper device for removing foreign substances attached to the surface of the windshield and wiping off rainwater or other fluid on the surface of the windshield to ensure a driver's front view.
In addition to this, the vehicle is provided with a washing liquid injection device that injects washing liquid onto the surface of the windshield to more easily remove foreign substances in the process of cleaning the surface of the windshield. In the washing liquid injection device, washing liquid is stored in a storage tank so as to be pumped by a washing pump (washer motor) and then sprayed onto the glass surface through an injection nozzle. Typically, the injection nozzles are provided in the cowl top or on the engine cover.
