Definitions
- the present invention relates to a laundry care appliance with a laundry chamber.
- rotatable laundry drums are usually used to hold laundry. Due to the rotation of a corresponding laundry drum, the laundry accommodated in the laundry drum can advantageously be wetted with washing liquid during the washing phase. If the corresponding laundry drum is rotated at a high speed during a final spin phase, the centrifugal force acting on the laundry causes washing liquid bound in the laundry to be expelled from the laundry, and the residual moisture in the laundry can thereby be advantageously reduced.
- drum-operated laundry care devices have a large volume and therefore require a large installation space.
- the use of drum-operated laundry care appliances is often correlated with high consumption of washing liquid and high energy consumption due to the large dead volume.

- the laundry care appliance 100 shown in FIG. 1 is designed as a drum-free laundry care appliance 100 which, in contrast to conventional washing machines, therefore has no rotatable laundry drum for receiving the laundry.
- rotation of the rotatable laundry drum ensures effective wetting of the laundry with the washing liquid during the washing process, and effective dehumidification of the laundry during a subsequent spinning process.
- the drum-free laundry care appliance 100 shown in FIG. 1 does not have a rotatable laundry drum for receiving the laundry, but rather a flexible laundry chamber 101 that can be closed in a fluid-tight manner for receiving the laundry.
- the laundry chamber 101 is in particular from a reversibly deformable material, such as an elastomer, formed to ensure the flexibility of the flexible laundry chamber 101.
- the laundry chamber 101 has a first opening 103-1 and a second opening 103-2, the first opening 103-1 being fluidically connected to a first chamber line 105-1, and the second opening 103-2 to a second chamber line 105 - 2 is fluidically connected.

- the second chamber line 105-2 has a second valve 107-2 which can close the second opening 103-2 in a fluid-tight manner.
- valve open position In a valve open position, the first valve 107-1 fluidically releases the first opening 103-1 and in a valve closed position, the first valve 107-1 closes the first opening 103-1.
- second valve 107-2 In a valve open position, the second valve 107-2 fluidly releases the second opening 103-2 and in a valve closed position, the second valve 107-2 closes the second opening 103-2.
- the laundry chamber 101 is thus designed as a laundry chamber 101 that can be closed in a fluid-tight manner.
- the first and second chamber lines 105-1, 105-2 are fluidically connected to a pump 111 of the laundry care appliance 100 by a first pump line 109-1.
- the pump 111 is connected to a washing liquid tank 113 of the laundry care appliance 100 by a second pump line 109 - 2 .
- a pump-out line 115 branches off from the second pump line 109 - 2 to a drain 117 .
- the pump 111 is designed to supply washing liquid from the washing liquid tank 113 through the first and second pump line 109-1, 109-2 and through the first and/or second chamber line 105-1, 105-2 to the laundry chamber 101 during a supply process.
- the pump 111 is also configured during a pumping-out process of fluid from the wash chamber 101 through the first and/or second chamber line 105-1, 105-2 and through the first and second pump line 109-1, 109-2 into the washing liquid tank 113 to be pumped out, or to pump the pumped-out fluid through the pump-out line 115 to a drain 117 .
- the pump 111 is designed to deliver fluid which, in addition to washing liquid, can also include air or a mixture of washing liquid and air.
- the pump 111 can not only pump out the washing liquid received in the laundry chamber 101 after the washing process, but also, in contrast to a drain pump used in conventional washing machines, also pump out air or a mixture of washing liquid and air from the laundry chamber 101 in order to thus creating a partial vacuum in the laundry chamber 101 .
- the pump 111 is formed as a liquid ring pump 111 in particular.
- the laundry care appliance 100 also has an air supply line 119 which is fluidically connected to the laundry chamber 101, in particular to the second opening 103-2 of the laundry chamber 101, which is fluidically connected to an air supply 121 for supplying air.
- the air supply 121 can in particular comprise a housing opening of the laundry care appliance 100 in order to supply air from an outside area of the laundry care appliance 100 .
- a third valve 107-3 is arranged on the air supply line 119, which can close the second opening 103-2 in a fluid-tight manner. In a valve open position, the third valve 107-3 fluidly releases the second opening 103-2 and in a valve closed position, the third valve 107-3 closes the second opening 103-2.
- the laundry care appliance 100 has a control 123 which is connected to the pump 111 and the valves 107-1, 107-2, 107-3 by control connections 125, and which is designed to to control pump 111 and valves 107-1, 107-2, 107-3.
- FIG. 2 shows a schematic view of the laundry care appliance 100 illustrated in FIG. 1 during a first step of a pumping-out process.
- the schematic structure of the laundry care appliance 100 shown in FIG. 2 corresponds to the schematic structure of the laundry care appliance 100 shown in FIG.
- the controller 123 activates the pump 111 and pumps with a first and second opening 103-1, 103 released by the first and second valves 107-1, 107-2 -2 wash liquid and air from wash chamber 101 through first and second openings 103-1, 103-2, through lines 105-1, 105-2, 109-1, 109-2 and 115 into drain 117.
- first or second valve 107-1, 107-2 can also fluidly close the first or second opening 103-1, 103-2, so that the pump 111 draws the washing liquid and air out of the laundry chamber 101 only can pump through one of the two openings 103-1, 103-2, ie either through the first opening 103-1 or through the second opening 103-2.
- the washing liquid When the washing liquid is pumped out through the second opening 103-2, which is arranged in particular on a chamber underside of the laundry chamber 101 facing the installation floor of the laundry care appliance 100, the force of gravity acting on the washing liquid supports the pumping-out process.
- FIG. 3 shows a schematic view of the laundry care appliance 100 illustrated in FIG. 1 during a second step of a pumping-out process following the first step.
- the controller 123 places the second valve 107-2 in the valve-closed position and the controller 123 places the third valve 107-3 in the valve-open position, so that the second opening 103-2, which is fluidly connected to the air supply line 119, is fluidly released so that the pump 111, which is still activated during the second step of the pumping-out process, now draws in an air flow from the air supply 121 through the air supply line 119 and through the second opening 103-2 into the laundry chamber 101.
- the suctioned air flow is passed through the laundry in the laundry chamber 101 and exits the laundry chamber 101 through the first opening 103-1, so that a constant air flow is passed through the laundry accommodated in the laundry chamber. Liquid particles adhering to the laundry can be detached from the laundry by the air flow and carried along in the air flow, so that the residual moisture in the laundry can advantageously be reduced.
- the air from the air supply line 119 is introduced into the partial vacuum inside the laundry chamber 101 .
- the negative pressure due to the partial vacuum in the laundry chamber 101 causes laundry items arranged at the edge of the laundry chamber 101 to be attracted, so that liquid particles in the air flow between the first and second openings 103-1 and 103-2 which do not separate are also drawn located directly in the flow cone of the air flow within the laundry chamber 101, so that in particular there is a balance between the residual moisture of the laundry and the humidity of the air flow, which corresponds to Bernoulli's equation.
- a particularly effective reduction in the residual moisture in the laundry in the laundry chamber 101 can thus be achieved by the air flow without the laundry care appliance 100 having to have a rotatable laundry drum for spinning the laundry.
- an effective reduction in the residual moisture in the laundry can be achieved within a dehumidification time of less than 10 minutes, in particular less than 5 minutes, the residual moisture values of the laundry after the dehumidification time being dependent on the textile.
- FIG. 4 shows a schematic view of a laundry care appliance with a laundry chamber according to a further embodiment of the present application.
- a laundry chamber 101 with an upper, first opening 103-1 and a lower, second opening 103-2 is shown only schematically in FIG.
- the laundry chamber 101 has a screen 129 with a large number of openings, not shown in Fig. 4, the screen 129 being arranged on the second opening 103-2 and extending in particular from the second opening 103-2 along the underside of the laundry chamber 101 extends.
- the air supplied through the air supply line 119 flows through the openings in the screen 129 into the laundry chamber 101 and advantageously penetrates the laundry, which is only shown schematically in FIG. 4, particularly over a large area.
- the air flow detaches liquid droplets 133 adhering to the laundry and carries them out of the laundry chamber 101 through the first opening 103-1, as a result of which an effective reduction in the residual moisture in the laundry can be ensured.
- a further screen 129 at the first opening 103-1, it being particularly advantageous for the entry and exit surfaces of the openings 103-1, 103 -2 arranged baffles 129 to ensure an effective reduction of the residual moisture of the laundry.
- Fig. 5 shows a schematic representation of a method for reducing residual moisture in laundry in a laundry care appliance 100.
- the method 200 comprises, as a first method step, the activation 201 of the pump 111 by the controller during a first step of the pump-out process in order to pump out washing liquid and air from the wash chamber 101 in order to create a partial vacuum within the wash chamber 101 and to compress the wash chamber 101.
- the method 200 comprises the fluidically releasing 203 of an air supply line 119 fluidically connected to the laundry chamber 101 by the controller 123 during a second step of the pumping-out process, which follows the first step, in order to induce a constant flow of air through the laundry received in the laundry chamber 101 and to reduce the residual moisture of the laundry received in the laundry chamber 101, the partial vacuum inside the laundry chamber 101 being maintained by the activated pump 111 during the second step.
