1 shows a schematic view of a laundry care appliance according to an embodiment of the present application. This in 1 The laundry care appliance 100 shown 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. In a conventional washing machine, 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.

This in 1 The illustrated drum-free laundry care appliance 100 according to the present application does not have a rotatable laundry drum for receiving the laundry, but instead a flexible laundry chamber 101 that can be closed in a fluid-tight manner for receiving the laundry. In this case, the laundry chamber 101 is in particular made of a reversibly deformable material, for example an elastomer, in order to ensure the flexibility of the flexible laundry chamber 101 . The laundry chamber 101 is thus designed as a laundry chamber 101 that can be closed in a fluid-tight manner.

The laundry chamber 101 has a first opening 103 - 1 which is fluidly connected to a first pump line 105 , the first pump line 105 in turn being fluidly connected to a pump 111 of the laundry care appliance 100 . The pump 111 is connected to a washing liquid tank 113 of the laundry care appliance 100 by a second pump line 109 . A drain line 115 branches off from the washing liquid tank 113 to a drain 117 .

The first pump line 105 has a first valve 107-1 which can close the first opening 103-1 in a fluid-tight manner. In a release position, the first valve 107-1 fluidly releases the first opening 103-1 and in a blocking position the first valve 107-1 closes the first opening 103-1, the first opening 103-1 in particular being on the floor of the laundry care appliance 100 facing away from the chamber top of the laundry chamber 101 is arranged.

The second pump line 109 has a second valve 107 - 2 which can block the second pump line 109 in terms of fluid technology. In a release position, the second valve 107-2 fluidly releases the second pump line 109, and in a blocking position, the second valve 107-2 closes the second pump line 109.

The laundry chamber 101 also has a ventilation 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 ventilation opening 103-2 is in this case fluidically connected by a ventilation line 119 to an outer opening 121 of the laundry care appliance 100, the outer opening 121 with one in 1 non-illustrated exterior of the laundry care appliance 100 is fluidically connected. A ventilation valve 107-3 arranged in the ventilation line 119 can fluidly open the outer opening 121 or fluidly close it.

The pump 111 is designed to supply washing liquid from the washing liquid tank 113 through the first and second pump lines 105, 109 and through the first opening 103-1 to the laundry chamber 101 during a supply process. In particular, the ventilation opening 103-2 can also be replaced by an in 1 another pump line (not shown) comprising a further valve connected to the pump 111, so that the pump 111 can also feed the washing liquid during the feed process, in particular via the further pump line, to the ventilation opening 103-2 of the laundry chamber 101.

The pump 111 is also formed during a pumping-out process of fluid from the laundry chamber 101 through the first opening 103-1, or in particular also through the ventilation opening 103-2, and through the first pump line 105 or through the second pump line 109 into the washing liquid tank 113 to be pumped out, or to pump the pumped-off fluid from the washing liquid tank 113 through the drain line 115 to a drain 117 .

The pump 111 according to the present application is designed to deliver fluid which, in addition to washing liquid, can also include air or a mixture of washing liquid and air. During the pumping-out process, 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 . In order to ensure this ability effectively, the pump 111 is formed as a liquid ring pump 111 in particular.

How from the 1 shows that the laundry care appliance 100 also has a washing liquid feed device 123 for feeding washing liquid, in particular fresh water, into the washing liquid tank 113, the washing liquid feed device 123 being fluidically connected to the washing liquid tank 113 by a feed line 125.

Even if this in the 1 is not shown, the washing liquid supply device 123 can also be fluidically connected to the laundry chamber 101 by a further supply line in order to supply the washing liquid, in particular fresh water or fresh water together with laundry care substance, directly to the laundry chamber 101.

As also from the 1 As can be seen, the laundry care appliance 100 has a control 127 which is connected to the pump 111, the valves 107-1, 107-2, 107-3 by control connections 129 and which is designed to control the pump 111 and the valves 107- 1, 107-2, 107-3 to control.

For further details regarding the laundry care appliance 100 according to the present disclosure, reference is made to the following explanations with regard to FIG 2 referred.

2 shows a schematic view of the in 1 illustrated laundry care appliance 100 during an air supply process.

the inside 2 The schematic structure of the laundry care appliance 100 shown corresponds to that in 1 illustrated schematic structure of the laundry care appliance 100, except that the fluid guide direction 131 of the pumped by the pump 111 from the laundry chamber 101 fluid is shown by arrows.

The Indian 2 The ventilation process shown is carried out here after the supply of washing liquid into the laundry chamber 101, the laundry accommodated in the laundry chamber 101 being in the 2 is not shown. In the 2 a liquid level 133 of washing liquid in the laundry chamber 101 is shown.

How from the 2 As can be seen, the controller 127 activates the pump 111 during the air supply process and pumps air at a first opening 103-1 and first pump line 105 released by the first valve 107-1 and at a second pump line 109 released by the second valve 107-2 from the laundry chamber 101 through the first opening 103-1 through the first and second pump line 105, 109 into the washing liquid tank 113 and from there through the drain line 115 into the drain 117.

The controller 127 also switches the ventilation valve 107 - 3 into the release position, so that a fluid connection between the ventilation opening 103 - 2 of the laundry chamber 101 and the outer opening 121 of the laundry care appliance 100 is provided by the ventilation line 119 . Air is thus supplied from the outside of the laundry care appliance 100 through the outside opening 121 through the ventilation line 119 and through the ventilation opening 103 - 2 , in particular from below, to the washing liquid in the laundry chamber 101 .

As a result, air bubbles 143 in the washing liquid within the laundry chamber 101 rise from the ventilation opening 103 - 2 and lead to an advantageous mixing of the washing liquid and thus to an improvement in the laundry care process of the laundry accommodated in the laundry chamber 101 .

Here, the controller 127 in particular controls the speed of the pump 111 in such a way that only air is pumped out through the first opening 103 - 1 of the laundry chamber 101 and no washing liquid.

3 shows a perspective view of a laundry chamber of a laundry care appliance during an air supply process.

In the 3 a device insert 135 of the laundry care device 100 is shown, which can be inserted into an in 3 device housing, not shown, of the laundry care device 100 can be inserted, or which can be pulled out of the device housing. The device insert 135 has a front element 137 with a gripping element 139 which can be gripped by the user of the laundry care device 100 in order to pull the device insert 135 out of the device housing or to push the device insert 135 into the device housing.

A laundry chamber 101 for receiving the laundry is arranged in the appliance insert 135 .

The laundry chamber 101 has a chamber interior 101 - 1 which is delimited by an inner chamber wall 101 - 2 of the laundry chamber 101 . The chamber interior 101-1 is defined by an in 3 not shown chamber cover of the device housing sealed fluid-tight and pressure-tight. In the 3 the laundry accommodated in the laundry chamber 101 and the washing liquid accommodated in the laundry chamber 101 are not shown.

The chamber inner wall 101-2 of the laundry chamber 101 has a ventilation projection 141 which is arranged in particular on the chamber underside 101-3 of the laundry chamber. The ventilation projection 141 protrudes into the chamber interior 101 - 1 of the laundry chamber 101 and the ventilation opening 103 - 2 is arranged in the ventilation projection 141 .

How from the 3 As can be seen advantageously, during the air supply process, air flows from the ventilation opening 103-2 into the chamber interior 101-1 of the laundry chamber 101, as a result of which air bubbles 143 are formed, which lead to an effective mixing of the washing liquid in the laundry chamber 101.

4 shows a schematic representation of a method for supplying air into a laundry care appliance.

The method 200 has as a first step the activation 201 of the pump 111 for pumping fluid out of the laundry chamber 101 by the controller 127 during an air supply process.

The method 200 has, as a second step, the controller 127 moving 203 the ventilation valve 107-3 to the release position in order to supply outside air through the ventilation line 119 and through the ventilation opening 103-2 to the washing liquid in the laundry chamber 101, and to remove air bubbles 143 in the to generate washing liquid.

All of the features explained and shown in connection with individual embodiments of the invention can be provided in different combinations in the object according to the invention in order to realize their advantageous effects at the same time.

The scope of protection of the present invention is given by the claims and is not limited by the features explained in the description or shown in the figures.
