Problems solved by technology

It has the disadvantage that these sensors are usually placed at different points in the laundry dryer, which can lead to a high degree of inaccuracy in the measured sensor signals due to the fact that the sensors detect different measurement points
In addition, the sensors generally require a large installation space, so that the arrangement cannot be flexibly designed, and generally greater distances between the actual measuring object and the sensor result, and the sensor signals are correspondingly inaccurate

Embodiment Construction

[0070] figure 1 A vertical section through a laundry dryer according to the invention is shown, which is designed as a condensation dryer, wherein the arrows indicate the flow direction of the process air. Other implementations are contemplated.

[0071] figure 1 The laundry dryer 1 shown in has a drum 3 rotatable around a horizontal axis for receiving laundry, not shown here, to be dried, for driving the laundry in motion during the rotation of the drum A piece 5, 22 is mounted inside said drum. Process air is guided through the drum 3 in the process air line 2 by means of a process air blower 6 via an air-to-air heat exchanger 14 and an electric heater 4 . In this case, the air heated by the electric heater 4 is guided into the drum 3 via the drum inlet 19 from the rear, ie from the side of the drum 3 opposite the door 12 , through the perforated bottom of the drum 3 .

[0072] After exiting the drum 3 , the moisture-laden process air flows through the filling opening of...

Abstract

The invention relates to a clothes dryer 1 with the following parts: a control device 8; a drum 3 for receiving laundry items, in which at least one laundry driver 5, 22 is arranged, with a sensor arrangement 23 with at least two sensors 24, 25, 26, 27 in the laundry driver 5, 22, an autonomous power supply 28 and an interface 29 for wireless data communication; and at least one evaluation unit 30for sensor signals from sensor arrangement 23, wherein the control device 8 and sensor arrangement 23 being set up to communicate wirelessly with one another, and at least two sensors 24, 25, 26 , 27of the sensor arrangement 23 are based on the same measuring principle and are arranged along the laundry driver 5, 22. The invention also relates to a method for operating such a clothes dryer.

Description

technical field [0001] The present invention relates to a laundry dryer with an improved control device and a method for its operation. In particular, the invention relates to a laundry dryer having: a control device; a drum for receiving laundry, in which at least one laundry carrier is arranged, wherein a sensor assembly with at least two sensors , a self-sufficient energy supply device and an interface for wireless data communication are located in the laundry belt; and at least one evaluation unit for the sensor signals of the sensor assembly, wherein the control device and the sensor assembly are arranged for communicate with each other wirelessly. Background technique [0002] Laundry dryers are developed with the aim of designing more reliable and easier operation for the user, as well as the continuous improvement of the drying programs implemented here in terms of performance, time, energy consumption and environmental compatibility. For this purpose, the possibil...
