Abstract
Abstract This invention is for a non-fogging mirror. Heated water flowing through a pipe section such as a shower arm is used to prevent fogging; the pipe section has an outlet and an inlet located in its surface. Means located within the pipe section induce the flow of water into the outlet or the inlet or both. The outlet and the inlet are connected to a conduit which is joined in heat-conducting relationship to the back of a reflecting surface.
