Definitions
- the present invention relates to a method and a device for drying washes.
- a crease protection phase is added at the end of a drying program or a drying phase.
- a drying program usually has a so-called heating phase, a subsequent actual drying phase and a subsequent cooling phase.
- the drum is usually rotated continuously. This also applies during the cooling phase, when only the heating is switched off. If the dried laundry is not immediately removed from the drum at the end of a drying program, creases can become entangled in the laundry. To prevent this, the drum is either continuously rotated during a subsequent crease phase or the drum is rotated intermittently.
- the laundry in the drum is loosened again and again, so that no creases can be fixed in the laundry.
- the intermittent rotation of the drum is usually carried out according to a fixed pattern, such as, for example, two minutes of drum stoppage and then fifteen seconds of drum rotation. This intermittent lasts either until the end of the anti-crease phase, which can take up to three or five hours, or until the laundry is removed from the drum.
- a disadvantage of this anti-crease phase is the fact that the laundry is subjected to a further load due to the drum movement. Due to the constant switching on and off, the drive motor and the switching elements for switching the drive motor on and off are still loaded.
- the object of the present invention is to provide a method and a device for drying laundry, which has an anti-crease phase, in which the laundry and also the components of the device are protected, and in which the formation of creases is optimally avoided and energy consumption is reduced.
- a drying program is followed by a crease phase in which the laundry is moved at times and is not moved at times.
- the water is only minimally agitated or loosened during the wrinkling phase and is therefore treated very gently, and wrinkling can be optimally avoided.
- the motor for rotating the drum is switched on and off less frequently, in particular towards the end of the knitting phase, the switch-on time of the drum movement is greatly reduced, so that the components for drum movement, such as the motor, relays for switching the motor on and off, and drum mounting are less stressed be and thus the life and reliability of the device is increased.
- energy is saved because the on-time of the drum movement is greatly reduced overall during and during the knitting phase.
- the movement component can be optimally adapted to the preselected drying program or to the preselected degree of dryness or the selected type of laundry. For example, a "Büelfeucht" drying ram needs a slightly higher weight percentage than one Drying program "Cupboard dry” or "Very dry”. Furthermore, the amount of movement can be optimally adapted to the amount of laundry in the drum. For each operating state, the amount of movement of the laundry can therefore be minimized so that the laundry and the components of the device are protected and the energy consumption is reduced.
- the movement of the laundry during the crease phase is carried out as a function of measured variables and parameters, which are recorded in previous phases of a drying program and / or during the crease phase.
- Measured variables and parameters can also be taken into account here, which are recorded during a heating phase at the beginning of a drying program and / or during a cooling phase at the end of a drying program.
- the rotatable drum has rotational movement periods and standstill periods during the crease phase.
- the drum can be rotated in one direction of rotation and / or reversely rotated in different directions of rotation.
- the duration of an anti-crease phase is preferably one to five hours.
- the duration of the crease phase is subdivided into four time segments, the movement components between 20% and 90% in a first time segment and between 10% and 70% in a second time segment, and the movement components in a third time segment Movement shares are between 1% and 60% and in a fourth period the movement shares are between 1% and 30%.
- An apparatus for drying laundry has a rotatable drum for moving the laundry and a control device which is able to carry out the method steps and method sequences outlined above.
- the device has a control device with an input device and a timing element.
- the device has sensor devices for detecting measured variables and parameters which are fed to the control device and are processed in the control device in accordance with the above-mentioned procedures.
- the device for drying laundry has a heater for heating the drying air, a motor for driving the drum and a blower for conveying the drying air.
- Figure 1 shows a device for drying laundry.
- a device for drying laundry has a housing 1, in which a drum 2 is rotatably mounted, a loading door 3, a front end plate 4, a supply channel 5 for drying air, in which a heating device 6 is arranged, one Outlet duct 7 for drying air, in which a blower 8 is arranged and a motor 9, which drives the drum 2 via a belt 10. Furthermore, a control device 11 is provided, which comprises an input device 12 and a timer 13. A first temperature sensor 14 is arranged in the supply air duct 5 adjacent to the entry into the drum 2, a second temperature sensor 15 is arranged in the outlet duct 7 adjacent to the drum 2. Two electrodes 16 for detecting the conductivity of the laundry and or the drying air are arranged on the front bearing plate 4. The first temperature sensor 14, the second temperature sensor 15 and the electrodes are connected to the control device 11, which is able to process the signals from the sensors and the input device 12.
- the device for drying laundry shown above can be designed as an exhaust air dryer or as a condensation dryer.
- the device for drying laundry shown in Figure 1 can with further sensors, such as a laundry temperature sensor or the like, which are required to carry out the method sequences and method steps set out below.
- the motor for rotating the drum is switched on and off less frequently, in particular towards the end of the anti-crease phase, the switch-on time of the drum movement is greatly reduced, so that the components for drum movement, such as motor, relay for switching the motor on and off and drum mounting are less stressed be and thus the life and reliability of the device is increased. Furthermore, energy is saved because the on-time of the drum movement is greatly reduced overall during and in the course of the crease phase.
- the movement component can be optimally adapted to the preselected drying program or to the preselected degree of dryness or the selected type of laundry.
- a drying program called "ironing moisture” requires a somewhat higher proportion of movement than a drying program "cupboard dry” or "very dry”.
- the loading movement proportion can be optimally adapted to the amount of laundry in the drum. For each operating state, the amount of movement of the laundry can therefore be minimized, so that the laundry and the components of the device are protected and the energy consumption is reduced.
- the movement of the laundry during the crease phase can be carried out as a function of measurement variables and parameters that are recorded in previous phases of a drying program and / or during the crease phase.
- Measured variables and parameters can also be taken into account here, which are recorded during a heating phase at the beginning of a drying program and / or during a cooling phase at the end of a drying program.
- the rotatable drum has rotational movement periods and standstill periods during the crease phase.
- the drum can be rotated in one direction of rotation and / or reversely rotated in different directions of rotation.
- the duration of a crease phase is preferably one to five hours.
- the duration of the crease phase is divided into four time segments, the movement components between 20% and 90% in a first time segment and between 10% and 70% in a second time segment and the movement components in a third time segment Movement shares are between 1% and 60% and in a fourth period the movement shares are between 1% and 30%.
- the drum movement can be switched off for 104 s and switched on for 16 s in a first time period be, and in a second period the drum movement is switched off for 284 s and switched on for 16 s and in a third period the drum movement is switched off for 584 s and switched on for 16 s and in a fourth period the drum movement is switched off for 584 s and for 16 s to be on.
- a crease phase is provided following a drying program, in which the laundry is temporarily moved and temporarily not moved.
- This crease phase serves to prevent wrinkles from being fixed in the laundry by loosening the laundry regularly.
- the laundry is moved minimally in the course of the crease phase, so that creasing is just avoided.
