Portable electric heating ice scraper

Abstract

A portable electric heating ice scraper with an elongated housing, configured to remove ice from a windshield. The housing includes: a front housing portion including a front housing end and a scraper disposed at the front housing end, and a rear housing portion including a handle and a rear housing end. An electric-powered fan that generates an airflow in a direction of the scraper and at least one electric-powered heating element configured to heat the airflow are disposed in the housing. The front housing portion and the rear housing portion approximately extend on a plane in a longitudinal direction of the housing or the front housing portion is curved at an angle not greater than 35° relative to the rear housing portion in the longitudinal direction of the housing.
