Abstract
Official abstract text for this publication.
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, such as 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for testing a Peltier element disposed in an electrical appliance, the method comprising the following steps: providing a Peltier element, said Peltier element comprising a warm side and a cold side, the cold side of which is positioned to come into contact with the skin of a user when the Peltier element is in use; applying a voltage (V) to the Peltier element; switching off the voltage (V) at the end of a defined period of time; measuring th…
