| 20090031734 | CIRCUIT ARRANGEMENT FOR A PELTIER MODULE - A circuit arrangement for a Peltier module for use in a Peltier heat pump for a tumble dryer with the circuit arrangement including a Peltier module having at least one series arrangement of Peltier elements, with each series arrangement of Peltier elements being configured to receive voltage; and a two-position transfer switch wherein at a first position voltage is applied to the Peltier module and at a second position voltage is not applied to the Peltier module and the Peltier module is connected to another electrical device. | 02-05-2009 |
| 20090049843 | Domestic Appliance Comprising a Thermoelectric Heat Pump - A domestic appliance, which may be a tumble dryer, includes a thermoelectric heat pump; at least one series of Peltier elements operationally associated with the heat pump and driven by a supply voltage for producing heat during appliance operation wherein the resistance of the Peltier elements increases with increasing temperature and wherein a threshold temperature for the Peltier elements is defined; and a heat flow path for dissipating heat produced by the Peltier elements wherein at a maximum temperature of the Peltier elements above a normal operating temperature and below the threshold temperature the power of the heat dissipated through the heat flow path is substantially equal to the electrical power drawn by the Peltier elements from the supply voltage. | 02-26-2009 |
| 20090049844 | Circuit Arrangement for a Peltier Module - A circuit arrangement for a Peltier module for use in a Peltier heat pump for a tumble dryer with the circuit arrangement including a Peltier module having at least one series arrangement of Peltier elements actuable by a DC voltage. Also included is a rectifier operatively associated with a power supply and at least one series arrangement of Peltier elements for producing a rectified DC voltage for use by said Peltier elements. The number of Peltier elements and the manufacturer type of Peltier elements are selected in a manner wherein the Peltier elements of the series arrangement are operated by actuating the series arrangement with the rectified power supply at an operating voltage that is suitable for the use of the Peltier module in a Peltier heat pump. | 02-26-2009 |
| 20100145525 | METHOD AND CIRCUIT ARRANGEMENT FOR SECURE CONTROL OF ACTUATORS, SENSORS AND/OR USERS IN AN ELECTRICAL DEVICE COMPRISING THE SAME IN PARTICULAR IN AN ELECTRICAL DOMESTIC APPLIANCE - A method for secure control of one of actuators, sensors, and loads in an electrical appliance, with at least two switch bodies operated in accordance with an AND logic gate for effective switching of the one of actuators, sensors, and loads by control signals acting on the at least two switch bodies. A continuous signal and a pulse signal are issued as control signals to a number of bistable control bodies corresponding to a number of the switch bodies, which are put into a switched-on state only by issuing the continuous signal and the pulse signal which occurs during issuing of a relevant continuous signal, in which the switch bodies are effectively switched, and put into a switched-off state in which the switch bodies are switched off solely by switching off the continuous signal and kept in this switched-off state even if the relevant continuous signal is issued once more. | 06-10-2010 |
| 20110016889 | HEATING APPARATUS HAVING AT LEAST TWO THERMOELECTRIC MODULES WHICH ARE CONNECTED IN SERIES - A heating apparatus including at least two thermoelectric modules connected in series, and at least one switching arrangement connected in parallel with one of the at least two thermoelectric modules such that electrical current flows via the at least one switching arrangement in an event of a failure of the one of the at least two thermoelectric modules. | 01-27-2011 |
