Abstract:
A laundry drying machine with a heat pump system comprises a process air circuit including a rotating drum, a blower and a heater, a refrigerant circuit including a compressor, a condenser, an expansion device, an evaporator, the condenser and evaporator being in heat exchange relationship with the process air circuit, an auxiliary condenser cooled by an air flow driven by a fan, and at least two temperature sensors placed in the process air circuit and/or in the refrigerant circuit. A method for controlling the laundry drying machine includes receiving an input indicating a desired behavior of the laundry drying machine selected from the group consisting of optimized use of energy, overall drying time and fabric care, and controlling components of the machine according to signals from the two temperature sensors and according to the desired behavior.
Abstract:
Example dryers and washer-dryers having a closed process air circuit having a drum, a condenser downstream from the drum for dehumidifying warm moist air, and a thermoelectric device having a cold side arranged in the process air circuit downstream from the drum are disclosed. Example thermoelectric devices have a warm side cooled by a fluid which is circulated in a liquid/air heat exchanger arranged in the process air circuit downstream from the condenser. Using the disclosed architectures, appliance design can be simplified without decreasing overall system performance.
Abstract:
A method for drying clothes in a household dryer having a drying chamber, a temperature sensor for monitoring temperature an air exhaust temperature from the chamber, and a control system for maintaining a temperature in the drying chamber close to a set point temperature by selecting the set point temperature on the basis of at least said based on the air exhaust temperature.

Abstract:
Disclosed are methods for detecting the cycle termination of a household tumble dryer having sensors for measuring at least two different parameters related to the drying process. In a an example method for detecting the cycle termination of a household tumble dryer having sensors for measuring at least two different parameters related to a drying process, signals from the sensors are combined according to a predetermined algorithm in order to improve the accuracy of said detection.
