Definitions
- the present invention relates to a washer/dryer wherein the dryness value of laundry is detected during the washing/drying process.
- the aim of the present invention is the realization of a washer/dryer wherein the moisture content s of the laundry is detected accurately during the washing/drying process.
- the moisture content of the laundry that is dried by agitating in the drum and blowing hot air thereon is detected by a humidity sensor and the control unit determines whether or not the laundry is dry by evaluating the data received from the humidity sensor.
- the control unit does not use in calculation the moisture content of zero or near to zero detected by the humidity sensor within a certain time duration, only takes into account those values that are different from zero or near to zero values. Then, the control unit calculates the average of the moisture data taken into consideration and regulates the drying process according to calculated average moisture content.
- control unit does not take into consideration the data received at instances when the laundry does not contact with the humidity sensor, only takes into consideration the data received at instances when the laundry contacts with the humidity sensor.
- control unit does not take into consideration the data received at instances when the laundry does not contact with the humidity sensor and data received at instances when the dry parts of the laundry contact the humidity sensor, only takes into consideration the humidity data received when the wet parts of the laundry contact the humidity sensor.
- Figure 1 - is the schematic view of a washer/dryer.
- the washer/dryer (1) comprises a drum (2) wherein laundry (L) is emplaced, a humidity sensor (3) disposed inside the drum (2) that detects the moisture content of the laundry (L), and a control unit (4) that regulates the drying process by evaluating the data received from the humidity sensor (3).
- the humidity sensor (3) is constituted of two plate shaped electrodes placed inside the drum (2).
- the moisture content of the laundry (L) is detected by the humidity sensor (3) through measuring the resistance of the laundry (L).
- the current that passes through one of the electrodes used for detecting moisture passes over the laundry (L) rotating in the drum (2) and reaches the other electrode.
- the current flowing through the electrodes is high when the laundry (L) is wet and less when the laundry (L) is dry.
- the moisture content of the laundry (L) is determined by correlating with the parameters of the current between the electrodes. A very high resistance, thus a current of close to zero between the electrodes and respectively a moisture content of close to zero is detected at instances when the laundry (L) rotating inside the drum (2) does not contact the electrodes.
- the momentary moisture contents of the laundry (L) in the drum (2) is measured by the humidity sensor (3) and an average moisture content (H average) is calculated by the control unit (4) according to data that are higher than the moisture data of zero or near to zero values received from the humidity sensor (3).
- the drying process is regulated according to the calculated moisture content by controlling the operation of the motor that rotates the drum (2) and the heater that heats the drying air..
- the moisture data of zero or near to zero values not included in the calculation of the average moisture (H average) by the control unit (4) are the moisture content data received at instances when the laundry (L) does not contact the humidity sensor (3).
- the moisture content data detected that are higher than the zero or near to zero values is the data received at instances when the laundry (L) contacts the humidity sensors (3).
- the moisture data received at instances when the laundry (L) does not contact the humidity sensor (3) are not used by the control unit (4) in calculating the average moisture (H average) and only the moisture data received at instances when the laundry (L) contacts the humidity sensor (3) are used in calculating the average moisture (H average).
- the data received at instances when the dry parts of the laundry (L) contact with the humidity sensor (3) is not taken into consideration by the control unit (4) in calculating the average moisture (H average).
- the control unit (4) only takes into consideration the moisture data received at instances when the wet parts of the laundry (L) contact the humidity sensor (3) and the data received at instances when the wet parts of the laundry (L) contact the humidity sensor (3) are used in calculating the average moisture (H average). .
- the actual moisture content of the laundry (L) is calculated by the control unit (4) independently from the amount of laundry (L) loaded into the drum (2) and by only evaluating the contact status of the laundry (L) with the humidity sensor (3), thus achieving a satisfactory drying performance in the washer/dryer (1).

Abstract
La présente invention concerne un lave-linge/sèche-linge (1) comprenant un tambour (2) dans lequel est positionné le linge (L), un capteur d'humidité (3) placé à l'intérieur du tambour (2) qui détecte la teneur en humidité du linge (L), et une unité de commande (4) qui calcule la moyenne des données d'humidité (H average) sans utiliser les données d'humidité des valeurs zéro ou pratiquement zéro détectées par le capteur d'humidité (3) dans le linge (L) pendant un certain temps, en prenant uniquement en compte les données d'humidité qui sont différentes de ces données d'humidité, et régule le processus de séchage selon la teneur en humidité moyenne calculée (H average).
