Water-drop-repellent mirror including a vibration plate and heating means
First Claim
1. A water drop repellent mirror for outdoor use, comprising a mirror glass having a rear surface with a edge and provided with a light reflecting layer at a rear side;
- a vibration plate connected with at least a part of said edge of said rear surface of said mirror glass arranged so as to from a clearance between said mirror glass arranged so as to form a clearance between said mirror glass and said vibration plate;
vibration wave generating means connected with said vibration plate; and
heating means arranged on said rear side of said mirror glass so as to heat up said mirror glass.

Abstract
A waterdrop repellent mirror provide a vibration plate which piezoelectric oscillator is affixed on the back side of the mirror, and a heater is placed therein to heat up the mirror surface. The piezoelectric oscillator on the rear surface of the mirror give ultra sonic wave vibration to the mirror through the vibration plate. When mirror surface resonate by inputting the vibration of the oscillator to the mirror, any waterdrop sticked on the mirror surface are dispersed. Re-sticked fine mist of waterdrop or frozen frost on the mirror surface can be removed by heated up the mirror, thereby clear mirror surface can be secured.
