Problems solved by technology

[0009] A problem with the clothes drying machines disclosed in JP2000229200 and JP6312095 is that the system initiates a user-selected drying cycle and in any case keeps operating the drying cycle for a predetermined time, even when the drum is empty or the laundry is dry The same is true, thus causing useless waste of electric energy

Embodiment Construction

[0029] figure 1 The reference numeral 1 in , generally designates a rotatable tumble clothes dryer comprising an outer housing 2 resting on the floor, preferably by a plurality of feet.

[0030] The housing 2 supports a rotatable laundry drum 3 , which defines a drying chamber 4 for laundry 5 and preferably, but not necessarily, rotates about a horizontal axis of rotation 6 . In alternative embodiments not shown, the axis of rotation 6 may be vertical or inclined.

[0031] The drying chamber 4 preferably has a front access opening 7 which can be closed by a door 8 which is preferably hinged to the housing 2 .

[0032] The drum 3 can be rotated about the axis of rotation 6 by means of an electric motor which figure 1 Schematically shown in and denoted by reference number 9, the drum 3 is supplied with hot air heated by heating means, which in the figure 1 is schematically shown in and denoted by reference numeral 10, and the hot air is preferably fed into the drum 3 by a fan...

Abstract

A method of controlling a drying operation of a rotatable-drum laundry dryer (1) is provided. The rotatable-drum laundry dryer (1) comprises a rotatable drum (3) for loading laundry (5) and at least an electrode sensor (22) for sensing dryness of the laundry (5). The method comprises the steps of: detecting the presence / absence of moist laundry (5) inside the rotatable drum (3) by the electrode sensor (22); if presence of moist laundry inside the rotatable drum (3) is detected, starting a drying cycle; sensing dryness of the laundry (5) during the drying cycle; measuring a cycle time (TD) at which the sensed dryness reaches a preset dryness threshold; and if the cycle time (TD) is lower than a preset dryness threshold time (Sm), continuing the drying cycle for a first additional time (D1), and stopping the drying cycle at the end of the first additional time (D1).

Description

technical field [0001] The present invention relates to a method of controlling a rotatable drum type laundry dryer and a rotatable drum type laundry dryer implementing the method. Background technique [0002] There is known a method of controlling a rotatable tumble type laundry dryer in which: hot air is supplied into a rotatable drum to flow over laundry inside the drum; and is measured by an electrode sensor arranged to come into contact with the laundry when the drum rotates. an electrical parameter associated with humidity of the laundry; determining a dryness of the laundry based on the measured electrical parameter; and stopping the drying cycle when the measured electrical parameter reaches a predetermined value associated with a preset final dryness. [0003] More specifically, laundry dryers are known to include an electronic control unit that receives a plurality of voltage signals having a function related to an electrical parameter of the laundry, namely imped...
