Embodiment Construction

[0056] figure 1 A laundry dryer 1 with a horizontally rotatable laundry drum 2 in which the laundry W to be dried is located is shown in side view as a sectional view (see figure 2 (a)-(d) and image 3 (a)-(d)). The laundry dryer 1 also has an electrical resistance measuring device 3 for measuring the electrical resistance of the laundry W, said electrical resistance measuring device 3 having two measuring electrodes 4 arranged for contact with the laundry W, said measuring electrodes 4 being in front The bearing end cap 5 on the side is installed on the lower edge of the door opening.

[0057] The laundry dryer 1 is designed to apply a direct voltage or an alternating voltage to the measuring electrodes 4 . The resistance measuring device 3 is connected to a control unit 6 which can control the operation of the laundry dryer 1 either alone or in cooperation with an external server and / or an external control unit (eg a mobile control unit). In particular, the control unit ...

Abstract

The invention relates to a method for determining laundry properties in a tumble dryer (1) which comprising a horizontally rotatable laundry drum (2) and a resistance measurement device (3) with two measurement electrodes (4) and also a control unit (6). The method comprises that: a) the electrical resistance R between the measurement electrodes when the laundry drum (2) is rotating is measured depending on the time t; b) the electrical resistance RR(t) which is measured depending on the time t is averaged over a prespecified time period [delta]t and registered as a time-dependent average resistance value Rm(t); c) the time-dependent average resistance value Rm(t) is evaluated in respect of an initial average resistance value Rs and / or a change over time [delta]Rm / [delta]t in the time-dependent average resistance value Rm(t); d) the initial average resistance value Rs determined in step (c) and / or the change over time [delta]Rm / [delta]t in the time-dependent average resistance value Rm(t) determined in step (c) is evaluated in respect of an initial laundry dampness Hs and / or a type of laundry and / or the remaining drying time. The control unit (6) of a tumble dryer (1) is also designed to carry out the method according to one of claims 1 to 12.

Description

technical field [0001] The invention relates to a method for determining the properties of laundry in a laundry dryer and a laundry dryer suitable for this. In particular, the invention relates to a method for determining the properties of laundry in a laundry dryer with a horizontally rotatable laundry drum and a resistance measuring device with two measuring electrodes and a control unit , in the method the resistance R(t) between the measuring electrodes is measured based on time t while the laundry drum is rotating. The invention also relates to a laundry dryer which is configured to carry out the method. Background technique [0002] In laundry dryers, the moisture content of the laundry (also referred to simply as laundry moisture) is usually ascertained by means of electrical resistance measurements. In this case, the measuring electrodes used in the corresponding resistance measuring devices are usually arranged in the end shield or in the drum. For example, the m...
