In order to protect the laundry from wrinkling during the multiple spin-drying processes 139, 139-1, 139-2, the wash care process 127 comprises a plurality of supply processes 141, 141-1, 141-2, which are each carried out directly before the respective spin-drying process 139, 139-1, 139-2. Alternatively, the supplying process 141, 141-1, 141-2 may also be performed during the corresponding spinning process 139, 139-1, 139-2. Alternatively, the supplying process 141, 141-1, 141-2 may also be performed before and during the respective spin-drying process 139, 139-1, 139-2.
The plurality of supply processes 141 thus comprises a temporally last supply process 141-1 which is carried out before and/or during the temporally last spin-drying process 139-1, and the plurality of supply processes 141 comprises at least one supply process 141-2 which is temporally before the temporally last supply process 141-1.
During the respective supply process 141, 141-1, 141-2, the control device 121 activates the supply device 112 of the laundry care appliance 100 in order to supply the anti-wrinkling agent to the laundry in the washing drum 107.
The control device 121 can be designed to rotate the washing drum 107 at least half a drum revolution, in particular half or a full drum revolution, during the respective supply process 141, 141-1, 141-2, in order to ensure effective wetting of the laundry with the anti-wrinkling agent.
Mechanical forces are applied to the laundry by the washing drum 107 rotating during the respective spin-drying process 139 which temporally follows the respective supply process 141, 141-1, 141-2, in order to remove the washing liquid from the laundry by the centrifugal force generated thereby. In this case, the washing drum 107 rotates, in particular, at an abutment rotational speed, at which the laundry is brought into abutment with the washing drum 107. Alternatively, the washing drum 107 rotates, in particular, at a reduced rotational speed.
During the pre-wash process 131, during the main wash process 133 and/or during the at least one rinse process 135, 135-1, 135-2, 135-3, the washing liquid thrown off from the washing drum 107 can be re-supplied to the laundry in the washing drum 107 by the circulating pumping system of the laundry care appliance 100. The washing liquid pumped by the lye pump from the lye container 105 into the line 117 is re-supplied to the washing drum 107 via the inlet, so that a continuous circulation of the washing liquid is achieved in the line 117 during the circulation pumping process. In this case, the washing liquid pumped into the washing drum 107 via the inlet 117 is guided, in particular as a jet, mist or steam, onto the laundry portion received in the washing drum 107 in order to effectively wet the textiles. This results in optimum wetting of the laundry and an improved washing performance by effective wetting of the laundry.
The anti-wrinkling agent applied to the laundry reduces the likelihood of the laundry wrinkling during the spin-drying process 139, 139-1, 139-2. This provides the user of the laundry care appliance 100 with an advantageously clean and wrinkle-free laundry after the laundry care process 127, so that a time-consuming laundry ironing process can be dispensed with if appropriate. By eliminating the ironing process it is ensured that the laundry is not damaged. This enables the user of the laundry care appliance 100 to obtain a laundry which is advantageously clean and ready to wear with reduced expenditure of time.
Fig. 4 shows a schematic representation of a method for conditioning laundry in a laundry care appliance.
The method comprises a first method step: the supply device 112 is activated 201 by the control device 121 before and/or during at least one temporally preceding spin-drying process during the supply process 141, 141-1, 141-2 in order to supply an anti-wrinkling agent to the laundry in the washing drum 107.
The method comprises an optional second method step: during at least one temporally preceding spin-drying process, drum drive 111 is activated 203 by control device 121 in order to rotate the washing drum at an abutment rotational speed, so that the items of laundry are brought into abutment with the washing drum and the washing liquid absorbed in the items of laundry is at least partially removed from the items of laundry.
The method comprises a third method step: the temporally preceding spin-drying process is carried out 205 by the control device 121 during the laundry care process 127 in order to protect the laundry from wrinkling during the temporally preceding spin-drying process.
The method comprises a fourth method step: the supply device 112 is activated 207 by the control device 121 during the supply process 141, 141-1, 141-2 before and/or during at least one temporally last spin-drying process in order to supply an anti-wrinkling agent to the laundry in the washing drum.
The method comprises an optional fifth method step: during the temporally last spin-drying process, the drum drive 111 is activated 209 by the control device 121 in order to rotate the washing drum at the contact rotational speed, so that the items of laundry are contacted with the washing drum and the washing liquid absorbed in the items of laundry is at least partially removed from the items of laundry.
The method comprises the sixth method step: the temporally last spin-drying process is carried out 211 by the control device 121 during the laundry care process 127 in order to protect the laundry from wrinkling during the temporally last spin-drying process.
