A laundry dryer comprising a body; a drum which is disposed in the body and wherein the laundry is loaded; a fan for supplying air to the drum, a heating device for heating the drying air, a temperature sensor which is provided in the body and which is configured to measure the temperature of the drying air in the drum; a humidity sensor which is provided in the body and which is configured to measure the humidity of the laundry; a water delivery system which is configured to spray water into the drum; and a control unit which is configured to control the fan to supply air onto the laundry loaded into the drum, which is configured to control the heating device to heat the air to be supplied, which is configured to control the water delivery system, which is configured to determine the weight and textile type of the laundry in the drum by means of a control panel which provides user to select the textile type and/or the weight of the laundry loaded into the drum and/or by means of a sensor configured to measure the weight and/or textile type of the laundry and which is configured to determine the predetermined amount of water to be delivered into the drum depending on the weight of the laundry in the drum, characterized by the control unit which is configured to provide heated air to be supplied into the drum by controlling the fan and the heating device and which is configured to control the temperature sensor to periodically measure the temperature of the air and which is configured to control the humidity sensor to periodically measure the humidity rate of the laundry in order to detect the reaching of a predefined air temperature and a predefined humidity range for the determined textile type and which, when the data received from the temperature sensor is between 35° C and 45° C, configured to operate the water delivery system so as to deliver the amount of water which is predetermined according to the weight of the laundry in the drum into the drum - when it is determined that cotton laundry is loaded into the drum and when the data received from the humidity sensor is between 12% and 16%, and/or - when it is determined that viscose laundry is loaded into the drum and when the data received from the humidity sensor is between 30% and 35%, and/or - when it is determined that polyester laundry is loaded into the drum and when the data received from the humidity sensor is between 4% and 8%. the temperature of the drying air in the drum; a humidity sensor which is provided in the body and which is configured to measure the humidity of the laundry; a water delivery system which is configured to spray water into the drum; and a control unit which is configured to control the fan to supply air onto the laundry loaded into the drum, which is configured to control the heating device to heat the air to be supplied, which is configured to control the water delivery system, which is configured to determine the weight and textile type of the laundry in the drum by means of a control panel which provides user to select the textile type and/or the weight of the laundry loaded into the drum and/or by means of a sensor configured to measure the weight and/or textile type of the laundry and which is configured to determine the predetermined amount of water to be delivered into the drum depending on the weight of the laundry in the drum, characterized by the control unit which is configured to provide heated air to be supplied into the drum by controlling the fan and the heating device and which is configured to control the temperature sensor to periodically measure the temperature of the air and which is configured to control the humidity sensor to periodically measure the humidity rate of the laundry in order to detect the reaching of a predefined air temperature and a predefined humidity range for the determined textile type and which, when the data received from the temperature sensor is between 35° C and 45° C, configured to operate the water delivery system so as to deliver the amount of water which is predetermined according to the weight of the laundry in the drum into the drum - when it is determined that cotton laundry is loaded into the drum and when the data received from the humidity sensor is between 12% and 16%, and/or - when it is determined that viscose laundry is loaded into the drum and when the data received from the humidity sensor is between 30% and 35%, and/or - when it is determined that polyester laundry is loaded into the drum and when the data received from the humidity sensor is between 4% and 8%. - when it is determined that cotton laundry is loaded into the drum and when the data received from the humidity sensor is between 12% and 16%, and/or - when it is determined that viscose laundry is loaded into the drum and when the data received from the humidity sensor is between 30% and 35%, and/or - when it is determined that polyester laundry is loaded into the drum and when the data received from the humidity sensor is between 4% and 8%.
