Definitions
- the present invention relates to a method of controlling a rotatable-drum laundry dryer and a rotatable-drum laundry dryer implementing the method.
- Methods of controlling rotatable-drum laundry dryers are known, in which: hot air is fed into the rotatable drum so as to flow over the laundry inside the drum; an electric parameter associated with the laundry moisture is measured by means of an electrode sensor arranged in order to contact with the laundry when drum rotates; the dryness of the laundry is determined according to the measured electric parameter; and the drying cycle is stopped when the measured electric parameter reaches a preset value associated with a prefixed final dryness.
- laundry dryers comprising an electronic control unit which receives a plurality of voltage signals having an amplitude and/or a frequency associated with the electric parameter of the laundry, i.e. impedance or resistance, or conductance, and measured a prefixed number of times; the electronic control unit determines the dryness of the laundry according to the measured voltage signals, and controls the drying cycle according to determined laundry dryness.
- the electrode sensor may be configured to output a voltage signal which is proportional to the dryness of the laundry. Thus, more dried is the laundry, higher is its electric parameter and consequently bigger is the voltage signal outputted from the electrode sensor.
- the technical problem of the above-described prior-art laundry dryer is that when contacts between laundry and electrode sensor, during the drying cycle, are very few, an incomplete dryness condition of the laundry may be performed, since the electronic control unit may erroneously conclude (or determine, resolve) that the few number of contacts between the laundry and the electrode corresponds to a dry condition of the laundry.
- the electronic control unit determines a high average value and, as a consequence, calculates a high electric parameter (impedance or resistance or conductance), and erroneously associate the latter with a dryness condition.
- electronic control unit may incorrectly conclude (or determine, resolve) that an expected drying condition of the laundry has been reached, and it may and stop the drying cycle too early, even if the laundry is still wet.
- JP2000229200 discloses a clothes drying machine in which drying operation are controlled in the case of a small amount of laundry into the rotating drum.
- the drying machine is configured to start a drying course by measuring the number of contacts between electrode and laundry; to determine whether the laundry is a high load or small load based on the measured number of contacts; and if the determined laundry is a small load, to set the drying cycle period for twenty-five minutes, independently of the moisture of the laundry.
- JP6312095 discloses a clothes drying machine which dries laundry independently of the its quantity, by executing the drying operation by a drying time setting timer when a small quantity signal is outputted from a clothes quantity judging device, while executing the drying operation, monitoring the dried state if the small quantity signal is not outputted.
- the clothes are agitated, and each time when the clothes come to an electrode which operates as clothes detector, is detected repeatedly.
- a microcomputer incorporated in a control circuit outputs a small quantity signal from a clothes quantity judging device and forcibly executes the drying operation without monitoring the dried state of the clothes up to the time-up of a drying time setting timer.
- the drying operation is executed, judging the degree of dryness by the electrode.
- Clothes drying machines disclosed in JP2000229200 and in JP6312095 have the problem that systems starts the drying cycle selected by the user and maintains operating the same in any case for a preset time, even if the drum is empty or the laundry is already dry, causing a useless wastage of electric energy.
- a method of controlling a drying operation of a rotatable-drum laundry dryer comprising a rotatable drum for loading laundry and at least an electrode sensor for sensing dryness of the laundry.
- the method comprises: detecting the presence/absence of moist laundry inside the rotatable drum by the electrode sensor; if presence of moist laundry inside the rotatable drum is detected, starting a drying cycle; sensing dryness of the laundry during the drying cycle; measuring a cycle time at which the sensed dryness reaches a preset dryness threshold; if the cycle time is lower than a preset dryness threshold time, continuing the drying cycle for a first additional time, and stopping the drying cycle at the end of the first additional time.
- the first additional time is such that the time elapsed from the beginning of the drying cycle and the stopping of the drying cycle is a preset minimum dryness time.
- the first additional time is set as the difference from the preset minimum dryness time and the cycle time.
- the method comprises: if the cycle time is not lower than the preset dryness threshold time, continuing the drying cycle for a preset second additional time; and stopping the drying cycle at the end of the second additional time.
- the second additional time is between zero and ten seconds.
- determining the presence/absence of moist laundry inside the rotatable- drum comprises: performing a starting detection phase for a starting detection time; if no moist laundry has been detected during the starting detection time, performing one or more additional detection phases, each of which lasts an additional detection time; if no moist laundry has been detected during the additional detection phase/s, ending operation of rotatable-drum laundry dryer.
- the additional detection time is lower than the starting detection time.
- the invention regards also a rotatable-drum laundry drier comprising: a rotatable drum for loading laundry, a least an electrode sensor for sensing dryness of the laundry; feeding drying air means for feeding drying air into the drum, and rotating means for rotating the drum about an axis of rotation.
- the rotatable-drum dryer comprises electronic control means configured to: detect presence/absence of moist laundry inside the rotatable drum by the electrode sensor; if presence of moist laundry inside rotatable drum is detected, start a drying cycle; sense dryness of the laundry during the drying cycle; measure a cycle time at which the sensed dryness reaches a preset dryness threshold; if the cycle time is lower than a preset dryness threshold time, continue to perform the drying cycle for a first additional time, and stop the drying cycle at the end of the first additional time.
- the first additional time is such that the time elapsed from the beginning of the drying cycle and the stopping of the drying cycle is a preset minimum dryness time.
- the first additional time is set as the difference from the preset minimum dryness time and the cycle time.
- the electronic control means are further configured to: continue to perform the drying cycle for a preset second additional dryness time if the cycle time is not lower than the preset dryness threshold time; and stop the drying cycle at the end of the preset second increased cycle time.
- the second additional time is between zero and ten seconds.
- the electronic control means are further configured to: perform a starting detection phase for a starting detection time; if no moist laundry has been detected during the starting detection time, perform one or more additional detection phases; and if moist laundry have been detected during the additional detection phase/s, end operation of rotatable-drum laundry drier.
- each of the one or more additional detection phases lasts an additional detection time lower than the starting detection time.

- one opened side of the drum 3 of the laundry drier 1 is advantageously associated, in a rotatable and substantially air-tight way, to a perforated inner wall 12 fixed to a lateral wall of casing 2 and through which hot air flows into drum 3;
- the other opened side of the drum 3 is advantageously associated, in a rotatable and substantially air-tight way, to a flange 13 associated to casing 2 and interposed between door 8 and front access opening 7 of drum 3.
- flange 13 is fixed firmly to casing 2, and is positioned at front access opening 7 so as to project at least partly inside drum 3, so that its inner surface faces the laundry 5 when the latter is loaded into the drum 3.
- Heating device 10 may advantageously comprise one or more electric heating components, such as electric resistors (not shown) or, in an alternative embodiment, a heat pump.
- electric heating components such as electric resistors (not shown) or, in an alternative embodiment, a heat pump.

- a condensing device 15 which cools the drying air to condense the moisture inside it.
- condensing device 15 may be supplied with cold air from outside the drier, and feeds the moisture-free air to fan 11. It should be pointed out that condensing device 15 as described above applies, purely by way of example, to one possible embodiment of the present invention, and may be omitted in the case of an exhaust-type rotatable-drum laundry drier 1 (i.e. in which the hot and moisture-laden drying air from the rotatable laundry drum 3 is expelled directly out of rotatable-drum laundry drier 1).
- the rotatable-drum laundry drier 1 also comprises an electronic control system 16, which is configured to control the rotatable-drum laundry drier 1, advantageously on the basis of a drying cycle selected by a user via a user control interface 18.
- the electronic control system 16 advantageously comprises an electrode sensor 22 for detecting dryness of the laundry.
- the electrode sensor 22 is a contact electrode sensor type and comprises two metal plates 23 arranged on the flange 13 in a position facing the inside of the drum 3, for sensing the dryness of laundry by using impedances generated at opposite ends of the metal plates 23 according to moisture content of the laundry 5 when the later is brought into contact with the opposite metal plates 23, and forwards the dryness as a electrical signal, i.e. a voltage signal.
- electrical signal outputted by the electrode sensor 22 could be associated, for example, with the resistance and/or conductance of the laundry 5 sensed between the metal plates 23.
- the electrode sensor is configured to generate an oscillating electrical signal and vary the frequency of oscillation of the electrical signal according to the laundry moisture/dryness.
- the electronic control system 16 further comprises an electronic control unit 14, which is configured to control the electric motor 9, heating device 10 and/or fan 11 in order to regulate the rotation speed of the drum 3, the temperature and/or the flow rate of hot air entering the drum 3 according to preset temperatures and flow rates specified for the laundry drying cycle selected by the user.
- an electronic control unit 14 which is configured to control the electric motor 9, heating device 10 and/or fan 11 in order to regulate the rotation speed of the drum 3, the temperature and/or the flow rate of hot air entering the drum 3 according to preset temperatures and flow rates specified for the laundry drying cycle selected by the user.
- selectable laundry cycles may comprise for example, a "cotton laundry drying cycle”, a “synthetic fabric laundry drying cycle”, a “wool laundry drying cycle”, and a “delicate laundry drying cycle”.
- the electronic control unit 14 is further configured to:
- the electronic control unit 14 stops operation of the rotatable-drum laundry dryer 1.
- detecting the presence/absence of moist laundry 5 inside the rotatable drum 3 comprises both simply detecting the presence/absence of laundry inside the drum 3 (i.e. independently on the moisture of the laundry), and detecting the presence/absence of laundry having a prefixed degree of moisture (or in other words having a prefixed degree of dryness).
- the electronic control unit 14 is configured to sense (by using the electric signals coming from the electrode sensor 22) both if there is laundry or not inside the drum, and if the laundry is moist or not, i.e. if the dryness of the laundry sensed by the electrode sensor 22 is below or above a threshold value (DRL) which may preferably depend on the drying cycle selected by the user.
- DRL threshold value
- the electronic control unit 14 is further configured to:
- the first additional time Dl is such that the time elapsed from the beginning of the drying cycle and the stopping of the drying cycle is a preset minimum dryness time Tmin (e.g. 30 minutes).
- the first additional time Dl is set as the difference from the preset minimum dryness time Tmin and the cycle time TD at which the sensed dryness reaches a preset dryness threshold (e.g. if TD is 10 minutes, and Tmin is 30 minutes, then Dl is 20 minutes).
- drying cycle indicates the part of the cycle starting when the heating device 10, i.e. electric resistor or heat pump, is switched-on for the first time, and ending when the heating device 10 is permanently switched-off.
- the heating device 10 may be continuously switched on, or it may be repeatedly switched on and off according to a time pattern depending on the laundry cycle selected by the user.
- the above mentioned preset dryness threshold depends on the laundry cycle selected by the user.
- the electronic control unit 14 is configured to:
- DRL prefixed threshold value
- the dryness of the laundry i.e. based on the frequency of the electric signal outputted from the electrode sensor 22;
- the electronic control unit 14 compares the cycle time TD when sensed dryness reaches the preset dryness threshold with a preset dryness threshold time Sm, and if the measured cycle time TD is lower than a the dryness threshold time Sm, electronic control unit 14 continues to perform the drying cycle for a certain time (first additional time Dl), preferably for a period of time such that the time elapsed (e.g. measured) from the beginning of the drying cycle, reaches a preset minimum dryness time Tmin.
- first additional time Dl preferably for a period of time such that the time elapsed (e.g. measured) from the beginning of the drying cycle, reaches a preset minimum dryness time Tmin.
- the phase of "detecting the presence/absence of moist laundry 5 inside the rotatable drum 3 and starting a drying cycle if presence of moist laundry 5 inside the rotatable drum 3 is detected” has a sort of synergic effect with the phases of "measuring (or calculating, determining, estimating, detecting) the 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 Dl"; in fact if the phase of "detecting the presence/absence of moist laundry 5 inside the rotatable drum 3 and starting a drying cycle only if presence of moist laundry 5 inside the rotatable drum 3 is detected" did't comprised in the method, and if the user erroneously started a drying cycle without loading any piece of
- heating device 10 is turned-off, the electronic control unit 14 recognises the selected drying cycle/program and preferably performs a detach phase, wherein it turns-on and controls the electric motor 9 to rotate the rotatable laundry drum 3 for a preset detaching time so as to detach the laundry 5 from the inner surface of the rotatable laundry drum 3 for increasing the probability that laundry 5 is brought into contact with the electrode sensor 22.
- the preset detaching time could be set between ten and twenty seconds, preferably about fifteen seconds.
- the electronic control unit 14 performs a starting detection phase (block 110) for a starting detection time, during which it controls the electric motor 9 to rotate the rotatable laundry drum 3 with preset rotation speed/s, and determines the presence/absence of the moist laundry 5 inside the drum 3 based on the electric signal outputted from the electric sensor 22.
- electronic control unit 14 determinetes (i.e. concludes or resolves) presence of moist laundry based on the impedance of the laundry 5 sensed between the metal plates 23 and/or according to the frequency of the electric signal outputted from the electrode sensor 22.
- the additional detection time (ADT) is lower than the starting detection time of the starting detection phase (block 110).
- the electronic control unit 14 performs again the additional detection phase for the additional detection time ADT (block 150), whereas in positive case (YES output from block 180), the electronic control unit 14 confirms absence of moist laundry inside of the rotatable laundry drum 3 (i.e. according to the electronic control unit 14 there is no moist laundry in the drum) and advantageously stops operation of the rotatable-drum laundry dryer 1.
- the electronic control unit 14 If the electronic control unit 14 detects a moist laundry presence condition during the starting detection phase (YES output from block 120) or one of the additional detection phases (YES output from block 160), it controls the rotatable-drum laundry dryer 1 to perform the selected drying cycle (block 130).
- electronic control unit 14 starts drying cycle by switching- on/controlling the electric motor 9, the heating device 10 and the fan 11.
- the electrode sensor 22 provides voltage signals associated with the moisture contents of the laundry 5 so as to sense the dryness of the laundry 5, the electronic control unit 14 receives the electric signals from the electrode sensor 22 and measures the cycle time TD at which the sensed dryness reaches a preset dryness threshold (block 190).
- electronic control unit 14 after starting the drying cycle, repeatedly senses the dryness of the laundry and compares, preferably continuously, sensed laundry dryness with the preset dryness threshold; the electronic control unit 14 measures (calculates, detects, obtains) the cycle time TD corresponding to the time at which sensed dryness reaches the preset dryness threshold.
- the electronic control unit 14 checks if the cycle time TD is lower than a preset minimum dryness threshold time Sm (i.e. if TD ⁇ Sm) (block 200).
- the electronic control unit 14 concludes (or determines, resolves) an insufficient dryness condition, and continues to perform the drying cycle for a first additional time Dl (block 210), after which the drying cycle is stopped (block 220).
- Preferably electronic control unit 14 sets the first additional time Dl in such a way that the drying cycle ends when the time elapsed from the beginning of the drying cycle reaches a preset minimum dryness time Tmin.
- the electronic control unit 14 sets the first additional time Dl as the difference between the preset minimum dryness time Tmin and the cycle time TD at which sensed dryness reaches the preset dryness threshold.
- the electronic control unit 14 continues to keep switched on the electric motor 9, the fan 11 and the heating device 10 according to the selected drying cycle.
- the preset minimum dryness time Tmin may vary according to the selected drying cycle or may be a preset value, preferably comprised between twenty and thirty- five minutes, preferably about thirty minutes.
- the electronic control unit 14 concludes (or determines, resolves) an admissible dryness condition, and continues to perform the drying cycle for a preset second additional time D2 (block 230). In other words, if admissible dryness condition is detected, the electronic control unit 14 continues to perform the drying cycle, after the cycle time TD, for the preset additional time D2, after which the drying cycle is stopped (block 230).
- the preset additional time D2 depends on the selected drying cycle.
- the preset additional time D2 is between 0 and ten seconds; if D2 is 0 seconds, the drying cycle is stopped immediately or substantially immediately after the electronic control unit 14 concludes (or determines, resolves) that it has been reached the admissible dryness condition.
- electronic control unit 14 may preferably perform a final cooling phase (block 240), wherein drum 3 may be kept turning, and non-heated air (since the heating device 10 has been permanently switched-off) may be fed into drum by the fan 11 so as to lower the high temperature to a predetermined low temperature (e.g. 30°C) at which laundry 5 can be handled by the user.
- a predetermined low temperature e.g. 30°C
- control method may advantageously be encoded in software that can be loaded in the electronic control unit 14 of the rotatable-drum laundry drier 1 and designed to ensure that, when executed, the electronic control unit 14 becomes configured for controlling the rotatable-drum laundry drier 1 according to the provisions of the method.
- the laundry dryer of the present invention has the following advantages.
- the additional detecting phases permit the laundry dryer to improve detecting the condition of empty-drum or of already-dry laundry loaded, and in this case to immediately stop operating the laundry dryer, so as to decrease wastage of electric energy.
