METHOD FOR TESTING A PELTIER ELEMENT AS WELL AS A SMALL ELECTRICAL APPLIANCE WITH A PELTIER ELEMENT AND A SAFETY DEVICE

摘要

A method with the following steps is described for testing a Peltier element: - applying a voltage to the Peltier element, - switching off the voltage at the end of a defined period of time, - measuring the voltage at the Peltier element and - comparing the measured voltage with a reference value. Furthermore, a small electrical appliance (for example an electric shaver) with a Peltier element is described, which small electrical appliance has a safety device which ensures that a malfunction of the Peltier element cannot result in danger to the user.
