Description
Technical Field
The invention relates to a laundry care appliance with a control device.
Background
In conventional drum-operated laundry care appliances, a rotatable laundry drum is usually used for receiving laundry. By means of a corresponding rotation of the laundry drum, the laundry received in the laundry drum can advantageously be wetted with washing liquor during a washing phase.
However, conventional drum-run laundry care appliances have a large volume and therefore require a large presentation bottom (Aufstellboden). Furthermore, the use of drum-operated laundry care appliances is often associated with increased consumption of washing liquid and increased energy consumption due to the dead volume (Totvolumen).
DE 2650509 discloses a vacuum washing machine.
Disclosure of Invention
The object of the present invention is to provide a laundry care appliance in which flexible dosing can be achieved during a laundry care process.
This object is achieved by the subject matter having the features according to the independent claims. Advantageous embodiments are the subject matter of the dependent claims, the description and the drawings.
According to a first aspect, the object is achieved according to the invention by a laundry care appliance having: a laundry chamber for receiving laundry, which is flexible and can be closed in a fluid-tight manner; a wash reservoir for receiving wash liquor; a laundry care substance receptacle for receiving a laundry care substance, wherein the laundry care substance receptacle is fluidically connected to the laundry chamber; a pump which is fluidically connected to the wash liquor tank and to the laundry care substance receptacle, wherein the pump is designed to pump wash liquor from the wash liquor tank into the laundry chamber during a pumping process, and wherein the pump is designed to pump fluid from the laundry chamber into the wash liquor tank via the laundry care substance receptacle during a pumping process; a control device, which is connected to the pump with respect to control technology, wherein the control device is designed to: during the dissolving step, the pump is activated for pumping out a partial fluid volume of the fluid from the laundry chamber in order to pump the partial fluid volume of the fluid from the laundry chamber and via the laundry care substance receptacle into the washing liquid tank and to at least partially dissolve the laundry care substance received in the laundry care substance receptacle in the partial fluid volume of the fluid.
The laundry care appliance disclosed herein is in particular a tumbler-less laundry care appliance, i.e. a laundry care appliance without a rotatable laundry tumbler.
Thereby, technical advantages are achieved: the fluid pumped out of the laundry chamber by the pump during the dissolving step flows through the laundry care substance receptacle and can advantageously dissolve the laundry care substance received in the laundry care substance receptacle.
Here, however, the pump pumps a specific partial fluid quantity out of the laundry chamber, so that the specific partial fluid quantity which is pumped out during the dissolving step is supplied to the laundry care substance receptacle and at least partially dissolves the laundry care substance received in the laundry care substance receptacle.
In particular, the partial fluid quantity pumped out of the laundry chamber by the pump during the dissolving step is determined such that the pumped partial fluid quantity does not completely dissolve the laundry care substance received in the laundry care substance receptacle, so that a portion of the laundry care substance initially received in the laundry care substance receptacle remains in the laundry care substance receptacle after the dissolving step.
The part of the laundry care substance remaining in the laundry care substance receptacle after the dissolving step can be dissolved out of the laundry care substance receptacle during a further dissolving step
The laundry care substance can thus be dosed stepwise to the laundry in the laundry chamber during a plurality of subsequent washing steps. Thereby, the laundry care efficiency can be advantageously increased during the subsequent washing step.
The pump is fluidically connected to the laundry chamber and to the washing liquid storage tank. Thus, during the dissolving step, the pump pumps the partial fluid quantity of fluid pumped out with the laundry care substance dissolved therein subsequently into the washing liquid tank, so that the partial fluid quantity held in the washing liquid tank with the laundry care substance dissolved therein can advantageously be used for a subsequent washing step for laundry care in which the pump simply pumps the fluid with the laundry care substance dissolved therein back into the laundry chamber again.
Here, the pump (which includes in particular a liquid ring pump) is configured for: the invention relates to a method for cleaning laundry in a washing machine, comprising a washing liquid reservoir, a washing liquid receiving portion, a washing liquid storage portion, and a washing liquid storage portion.
In particular, the washing liquid tank is connected to the outlet via an outlet line, wherein a control-related outlet valve, which is connected to the control device, fluidically opens the outlet line in an open position or fluidically blocks the outlet line in a blocking position. Here, the control device is configured in particular during the dissolving step for: the outlet valve is switched into the open position, so that air which is displaced out of the washing liquid storage tank during the pumping of the partial fluid volume out of the washing chamber into the washing liquid storage tank can escape from the laundry care appliance via the open outlet line.
A laundry care appliance according to the present application is understood to be an appliance which is used for laundry care, i.e. for example for washing and/or drying laundry. In particular, such a laundry care appliance is understood to be a domestic laundry care appliance. That is, such laundry care appliances: the laundry care appliance is used in the household sector and treats household-customary quantities of laundry with the laundry care appliance.
In an advantageous embodiment, the control device is designed to: during a further dissolving step following the dissolving step, the pump is activated for pumping a further partial fluid quantity of fluid out of the laundry chamber in order to pump the further partial fluid quantity of fluid out of the laundry chamber and via the laundry care substance receptacle into the washing liquid tank and to dissolve the laundry care substance received in the laundry care substance receptacle at least partially in the further partial fluid quantity of fluid.
This achieves the technical advantage that: the further partial amount of fluid pumped from the laundry chamber into the laundry care substance receptacle within the scope of the further dissolving step can dissolve
A further quantity of laundry care substance received in the laundry care substance receptacle, so that an incremental (i.e. stepwise) dissolution of the laundry care substance received in the laundry care substance receptacle is achieved
A further quantity of laundry care substance, which is dissolved in a further partial quantity of fluid, is pumped from the laundry care substance receiver into the washing liquid tank.
In particular, the control device is configured to: the further dissolving step is repeated a plurality of times in order to activate the pump during the further dissolving step for pumping out the fluid of the further partial fluid quantities from the laundry chamber in order to pump the fluid of the further partial fluid quantities from the laundry chamber and via the laundry care substance receptacle into the washing liquid tank and to at least partially dissolve the laundry care substance received in the laundry care substance receptacle in the fluid of the further partial fluid quantities.
Thus, the further dissolving step can also comprise a plurality of further dissolving steps during which a plurality of further quantities of the laundry care substance received in the laundry care substance receiver can be dissolved.
In particular, the laundry care substance received in the laundry care substance receiver is completely dissolved after the further dissolving step (or after a plurality of further dissolving steps), so that no laundry care substance remains in the laundry care substance receiver, in particular after the further dissolving step (or after a plurality of further dissolving steps).
In an advantageous embodiment, the control device is designed to: during a return step following the dissolving step and/or the further dissolving step, the pump is activated for pumping wash liquor from the wash liquor tank in order to pump a return amount of fluid from the wash liquor tank into the wash chamber.
This achieves the technical advantage that: during the dissolving step, a partial amount of the fluid received in the washing liquid tank together with the laundry care substance dissolved therein can be effectively supplied to the laundry chamber during the return step, so that an effective laundry care can be achieved during the washing step.
In particular, during the step of back-leading, the pump is configured for: the return quantity of fluid pumped out of the wash liquor tank is pumped directly (i.e. in particular not via the laundry care substance receptacle) into the laundry chamber, so that the laundry care substance possibly remaining in the laundry care substance receptacle is not dissolved out of the laundry care substance receptacle during the return step.
In particular, the pump is directly connected to the laundry chamber via the first and/or third pumping line in order to pump a return quantity of fluid directly (i.e. in particular not via the laundry care substance receptacle) into the laundry chamber during the return step.
In an advantageous embodiment, the control device is designed to: during the dissolving step following the return step, a pump is activated for pumping out a dissolving amount of fluid from the laundry chamber in order to pump it from the laundry chamber and via the laundry care substance receptacle into the washing liquid tank and to dissolve the laundry care substance received in the laundry care substance receptacle at least partially (in particular completely) in the dissolving amount.
This achieves the technical advantage that: the fluid received in the laundry chamber after the return step (for example after the end of the washing step) can be used again for dissolving the remaining amount of the laundry care substance received in the laundry care substance receiver and for receiving this remaining amount in the washing liquid tank.
In particular, the quantity of the dissolving-out can be selected during the dissolving-out step such that the laundry care substance received in the laundry care substance receiver is completely dissolved in the dissolving-out quantity, so that no further laundry care substance remains in the laundry care substance receiver after the dissolving-out step.
Thus, during a further return step following the dissolving step, the remaining amount of the laundry care substance dissolved in the dissolving quantity can be fed back into the laundry chamber, so that the laundry care substance can be fed back into the laundry chamber during a further washing step.
In an advantageous embodiment, the control device is designed to: the dissolving step is repeated a plurality of times in order to activate the pump during a plurality of further dissolving steps for pumping a plurality of further dissolving quantities of fluid out of the laundry chamber in order to pump a plurality of further dissolving quantities of fluid out of the laundry chamber and into the washing liquor tank via the laundry care substance receptacle and to dissolve the laundry care substance received in the laundry care substance receptacle at least partially (in particular completely) in the plurality of further dissolving quantities of fluid.
This achieves the technical advantage that: in a plurality of washing steps in the laundry chamber, the laundry care substance can be repeatedly (i.e. stepwise) dissolved out of the laundry care substance receiver during a plurality of dissolving steps
So that a corresponding partial quantity of the dissolved laundry care substance is supplied again to the laundry chamber in the course of the plurality of return steps.
In an advantageous embodiment, the laundry care appliance has a pressure sensor for detecting the air pressure in the laundry chamber, wherein the pressure sensor is connected to the control device with regard to control technology, wherein the control device is designed to: activating the pump during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step for pumping the partial fluid quantity, the further partial fluid quantity, the dissolving quantity and/or the further dissolving quantity of fluid out of the laundry chamber, and wherein the partial fluid quantity, the further partial fluid quantity, the dissolving quantity and/or the further dissolving quantity is determined as a function of the air pressure in the laundry chamber detected by the pressure sensor.
This achieves the technical advantage that: the air pressure detected by the pressure sensor inside the laundry chamber enables an effective determination of the amount of fluid pumped out of the laundry chamber in each case.
Since the pump is in particular configured as a liquid ring pump (flintskeitring-Pumpe), the liquid ring pump is configured for: in addition to the washing liquid received in the laundry chamber, the washing liquid air mixture or air is also pumped out of the laundry chamber, whereby the air pressure inside the laundry chamber drops constantly during the pumping out, so that there is a direct relationship between the air pressure inside the laundry chamber and the amount of fluid pumped out.
In particular, the control device is configured to: during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, the pump is deactivated (dealivieren) when the air pressure detected by the pressure sensor is below an air pressure threshold.
By correspondingly deactivating the pump when a certain air pressure threshold is undershot, it is ensured that: a precisely defined amount of fluid is pumped out of the laundry chamber during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, so that a defined amount of laundry care substance can be dissolved from the laundry care substance receptacle.
In particular, the control device is configured to: during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, the pump is deactivated if the drop in the air pressure detected by the pressure sensor within a defined time interval exceeds a gradient limit value.
Alternatively, the drop in the process air pressure during a specific time interval can also be evaluated by the control device, so that the pump is deactivated when a specific gradient limit value is exceeded. It is thus also ensured that: a precisely defined amount of fluid is pumped out of the laundry chamber during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, so that a defined amount of laundry care substance can be dissolved from the laundry care substance receiver.
In an advantageous embodiment, the washing liquid storage tank has at least one liquid level sensor for detecting the level of the washing liquid in the washing liquid storage tank, wherein the control device is designed to: during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, the pump is deactivated when the liquid level detected by the liquid level sensor exceeds a liquid level threshold.
This achieves the technical advantage that: the amount of fluid pumped out of the laundry chamber can be advantageously determined as a function of the level of the fluid in the washing liquid reservoir. Since the pump pumps fluid from the laundry chamber into the washing liquid reservoir via the laundry care substance receptacle during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, the amount of fluid pumped out of the laundry chamber corresponds to the amount of fluid pumped into the washing liquid reservoir.
The amount of partial fluid pumped out of the laundry chamber during a dissolving step, the amount of further partial fluid pumped out of the laundry chamber during a further dissolving step, the amount of redissolution pumped out of the laundry chamber during a redissolution step and/or the amount of further redissolution pumped out of the laundry chamber during a further redissolution step can advantageously be determined on the basis of the difference between the initial level in the washing liquid reservoir and the level threshold.
In particular, the wash liquor tank has a plurality of level sensors for detecting a plurality of levels of fluid in the wash liquor tank and the pump is deactivated when the level detected by the respective level sensor exceeds a respective level threshold.
In an advantageous embodiment, the partial fluid quantity, the further partial fluid quantity, the dissolving quantity and/or the further dissolving quantity is determined as a function of the activation time of the pump during the dissolving process, the further dissolving process, the dissolving process and/or the further dissolving process.
This achieves the technical advantage that: the amount of fluid pumped can be detected in a simple manner as a function of the activation time of the pump. In particular, with a constant rotational speed of the pump, the volumetric flow of the fluid delivered by the pump is also kept constant, so that there is a direct correlation between the activation time of the pump and the amount of fluid delivered by the pump.
In an advantageous embodiment, the pump is designed as a variable-speed pump, and the partial fluid quantity, the further partial fluid quantity, the digestion quantity and/or the further digestion quantity is determined as a function of the speed of rotation of the pump during the dissolution process, the further dissolution process, the digestion process and/or the further digestion process.
This achieves the technical advantage that: the amount of fluid pumped can be detected simply from the number of revolutions of the pump. In particular, in the case of a variable number of revolutions of the pump, the volumetric flow of the fluid supplied by the pump is varied as a function of the number of revolutions of the pump, so that, during a defined period of time, a greater amount of fluid is supplied by the pump in the case of a high number of revolutions of the pump than in the case of a low number of revolutions of the pump. Thus, during the determined period of time, there is a direct correlation between the number of revolutions of the pump and the amount of fluid delivered by the pump, so that the control device can effectively determine the respective amount of fluid.
In particular, the partial fluid quantity, the further partial fluid quantity, the dissolving quantity and/or the further dissolving quantity is determined as a function of the number of revolutions of the pump and the activation time during the dissolving process, the further dissolving process, the dissolving process and/or the further dissolving process.
In an advantageous embodiment, the control device is designed to: activating a pump for pumping wash liquid from the wash liquid tank for pumping fluid from the wash liquid tank into the wash chamber prior to the dissolving step, and/or the control device is configured for: before the dissolving step, a pump (which is in particular designed as a liquid ring pump) is activated for generating a partial vacuum inside the laundry chamber.
Thereby, technical advantages are achieved: the fluid (in particular fresh water) stored in the washing liquid tank is fed into the washing compartment before the dissolution step, in order to ensure: during the subsequent dissolving step, a sufficient partial fluid volume is present in the laundry chamber so that the laundry care substance received in the laundry care substance receiver can be effectively dissolved.
Furthermore, the pump, which is in particular designed as a liquid ring pump, can generate a partial vacuum inside the laundry chamber before the dissolving step by partially pumping out air from the laundry chamber, so that the flexible laundry chamber is contracted, whereby the fluid received in the laundry chamber can be particularly advantageously pumped out of the laundry chamber during the dissolving step.
In an advantageous embodiment, the laundry chamber has a first receptacle opening, which is arranged in particular on that upper side of the laundry chamber which faces away from the lying bottom of the laundry care appliance, wherein the pump is fluidically connected to the first container opening via a first pumping line of the laundry care appliance, so that the washing liquid is supplied to the washing-goods compartment through the first pumping line and through the first container opening, and/or the laundry chamber has a second container opening, which is arranged in particular on that underside of the laundry chamber which faces the lying bottom of the laundry care appliance, wherein the pump is fluidically connected to the second container opening via a third pumping line of the laundry care appliance, in order to pump the washing liquid out of the washing chamber through the second container opening and through the third pumping line.
This achieves the technical advantage that: the first container opening, which is arranged in particular on the upper side of the laundry chamber, ensures that the washing liquid is effectively supplied into the laundry chamber, for example during the return step.
The second container opening, which is arranged in particular on the underside of the laundry chamber, ensures that the washing liquid is effectively pumped out of the laundry chamber, for example in order to pump out washing liquid consumed after a washing process from the laundry care appliance.
The third pumping line is connected in particular fluidically directly (in particular not fluidically via the laundry care substance holder) to the pump, so that the laundry care substance held in the laundry care substance holder cannot be unintentionally dissolved out during the pumping-out of the fluid through the third pumping line.
The first pumping line has, in particular, a first valve configured to: the first container opening is closed in a fluid-tight manner and the first valve is connected in terms of control technology to a control device. The control device is designed in particular to: the first valve is switched between an open position and a blocking position. In the open position, the first valve fluidically opens the first container opening, and in the blocking position, the first valve closes the first container opening.
The third pumping line has, in particular, a third valve configured for: the second container opening is closed in a fluid-tight manner and the third valve is connected in terms of control technology to a control device. The control device is designed in particular to: switching the third valve between an open position and a blocking position. In the open position, the third valve fluidically opens the second container opening, and in the blocking position, the third valve closes the second container opening.
In an advantageous embodiment, the laundry care substance receptacle comprises a receptacle recess of the laundry care appliance, in which a substance-receiving insert (substanzaufnahmeeinatz) for receiving laundry care substances is received, wherein the laundry chamber has a third container opening, which is arranged in particular on that upper side of the laundry chamber which faces away from the lying bottom of the laundry care appliance, wherein the third container opening is fluidically connected to the receiving recess, and wherein the pump is fluidically connected to the receiving recess via a fourth pumping line, in order to feed washing liquor from the laundry chamber into the substance-receiving insert received in the receiving recess and dissolve the laundry care substance received in the substance-receiving insert and subsequently pump out the dissolved laundry care substance through the fourth pumping line.
Thereby, technical advantages are achieved: during the dissolving step, the further dissolving step, the dissolving step and/or the further dissolving step, a corresponding amount of fluid can be effectively supplied from the laundry chamber into the receiving recess in order to effectively dissolve the laundry care substance.

Detailed Description
Fig. 1 shows a schematic view of a laundry care appliance according to an embodiment of the present application. The laundry care appliance 100 shown in fig. 1 is configured as a tumbler-less laundry care appliance 100, so that, unlike conventional washing machines, the laundry care appliance 100 does not have a rotatable laundry drum for receiving laundry. In conventional washing machines, the rotation of the rotatable laundry drum ensures an effective wetting of the laundry with the washing liquid during the washing process and an effective dewatering of the laundry during the subsequent spin-drying process.
The drum-free laundry care appliance 100 shown in fig. 1 according to the present application does not have a rotatable laundry drum for receiving laundry here, but instead has a flexible and fluid-tight closable laundry chamber 101 for receiving laundry. The laundry chamber 101 is constructed here in particular from a material that can be deformed in a reversible manner (for example an elastomer) in order to ensure the flexibility of the flexible laundry chamber 101. The laundry chamber 101 is thus constructed as a laundry chamber 101 which can be closed in a fluid-tight manner.
The laundry chamber 101 has a first container opening 103-1, which first container opening 103-1 is fluidically connected to a first pumping line 105, wherein the first pumping line 105 is in turn fluidically connected to a pump 111 of the laundry care appliance 100. The pump 111 is connected via a second pump line 109 to a wash liquor reservoir 113 of the laundry care appliance 100. A discharge line 115 leads from the wash liquid tank 113 to a discharge section 117.
The first pumping line 105 has a first valve 107-1, which first valve 107-1 is able to close the first container opening 103-1 in a fluid-tight manner. In the open position, the first valve 107-1 fluidically opens the first container opening 103-1, and, in the blocking position, the first valve 107-1 closes the first container opening 103-1, wherein the first container opening 103-1 is arranged in particular on the upper chamber side of the laundry chamber 100 facing away from the lying bottom of the laundry care appliance 100.
The second pumping line 109 has a second valve 107-2, which second valve 107-2 can fluidically block the second pumping line 109. In the open position, the second valve 107-2 fluidically opens the second pumping line 109, and, in the blocking position, the second valve 107-2 closes the second pumping line 109.
Furthermore, the laundry chamber 101 has a second container opening 103-2, which second container opening 103-2 is arranged in particular on the chamber underside of the laundry chamber 101 facing the lying bottom of the laundry care appliance 100. The second container opening 103-2 is connected fluidically to the pump 111 of the laundry care appliance 100 via a third pump line 119. The third valve 107-3 arranged in the third pumping line 119 can fluidically open the third pumping line 119 in the open position or fluidically close the third pumping line 119 in the blocking position.
Furthermore, the laundry chamber 101 has a third container opening 103-3, which third container opening 103-3 is arranged in particular on the upper side of the chamber of the laundry chamber 101 facing away from the lying bottom of the laundry care appliance 100. The third container opening 103-3 is fluidically connected to a laundry care substance holder 121, which is only schematically illustrated in fig. 1, for holding laundry care substance. Even though this is not shown in fig. 1, the laundry care substance receiving portion 121 comprises a receiving recess in which a substance receiving insert for receiving the laundry care substance is mounted.
The laundry care substance receptacle 121, in particular the receptacle recess, is fluidically connected to a fourth pumping line 122, which fourth pumping line 122 is in turn fluidically connected to the pump 111. The fourth valve 107-4 arranged in the fourth pumping line 122 can fluidically open the fourth pumping line 122 in the open position or fluidically close the fourth pumping line 122 in the blocking position.
The pump 111 is configured to: during the feeding process wash liquid from wash liquid storage tank 113 is fed into the wash chamber 101 through the first and second pumping lines 105, 109 and through the first container opening 103-1. Alternatively, the pump 111 can also feed washing liquid into the laundry chamber 101 during the feeding process, in particular through the third pumping line 119 and through the second container opening 103-2.
Furthermore, the pump 111 is configured for: during the pumping-out process, fluid from the laundry chamber 101 is pumped out through the second container opening 103-2 and the third pumping line 119 or through the third container opening 103-3, the laundry care substance receptacle 121 and the fourth pumping line 122. The fluid pumped by the pump 111 may be pumped into the wash liquor tank 113 through the first pumping line 105 and through the second pumping line 109, or the pumped fluid may be pumped from the wash liquor tank 113 through the drain line 115 to the drain 117.
The pump 111 according to the present application is designed for conveying a fluid which, in addition to the washing liquid, may also comprise air or a washing liquid air mixture. Thus, during the pump-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 (unlike the lye pumps used in conventional washing machines) pump out air or a washing liquid air mixture from the laundry chamber 101, in order thus to generate a partial vacuum in the laundry chamber 101. To effectively ensure this capability, the pump 111 is configured in particular as a liquid ring pump 111.
As can be seen from fig. 1, the laundry care appliance 100 furthermore has a wash liquor feed 123 for feeding wash liquor (in particular fresh water) into the wash liquor tank 113, wherein the wash liquor feed 123 is fluidically connected to the wash liquor tank 113 via a feed line 125.
Even though this is not shown in fig. 1, the washing liquid feed 123 can be fluidically connected to the laundry care substance receptacle 121 via a further feed line in order to feed the washing liquid (in particular fresh water) together with the laundry care substance directly into the laundry chamber 101.
As can also be seen from fig. 1, the laundry care appliance 100 has a control device 127, which control device 127 is connected via a control connection 129 to the pump 111 and to the valves 107-1, 107-2, 107-3, 107-4, and which control device 127 is designed to: the pump 111 and valves 107-1, 107-2, 107-3, 107-4 are controlled.
For further details regarding the laundry care appliance 100 according to the present disclosure, reference is made to the embodiment that follows with respect to fig. 2.
Fig. 2 shows a schematic view of the laundry care appliance 100 shown in fig. 1 during a dissolving step.
The schematic configuration of the laundry care appliance 100 shown in fig. 2 differs from the schematic configuration of the laundry care appliance 100 shown in fig. 1 only in that: the fluid guiding direction 131 of the fluid pumped out of the laundry chamber 101 by the pump 111 is shown by an arrow.
Here, the dissolving step shown in fig. 2 is carried out after the washing liquid is supplied into the laundry chamber 101, wherein the laundry received in the laundry chamber 101 is not shown in fig. 2.
As can be taken from fig. 2, the control device 127 activates the pump 111 during the dissolving step and pumps fluid from the laundry chamber 101 through the third container opening 103-3, through the fourth pumping line 122 and through the first pumping line 105 and the second pumping line 109 into the washing liquid tank 113 in case the third container opening 103-3 and the fourth pumping line 122 are opened through the fourth valve 107-4 and in case the second pumping line 109 is opened through the second valve 107-2.
Since the pump 111 is in particular configured as a liquid ring pump, the fluid pumped out of the laundry chamber 101 during the dissolving step may comprise washing liquid, air or a washing liquid air mixture. In particular, at the beginning of the dissolving step, the pump 111 generates a partial vacuum inside the laundry chamber 101 by pumping out air. Here, the partial vacuum generated compresses, in particular, the flexible laundry chamber 101, so that the washing liquid (or the washing liquid air mixture) can then be pumped out of the laundry chamber 101 by the pump 111 effectively during the dissolving step.
The fluid pumped out of the laundry chamber 101 by the pump 111, in particular the washing liquid and/or the washing liquid air mixture, flows through the third container opening 103-3 into the laundry care substance receptacle 121 and at least partially dissolves the laundry care substance received in the laundry care substance receptacle 121. The laundry care substance received in the wash liquor and/or the wash liquor air mixture flows through the fourth pumping line 122 and through the second pumping line 109 into the wash liquor tank 113 and can be held in the wash liquor tank 113 for one or more subsequent wash steps.
In order to allow air that is squeezed out of the wash liquid tank 113 during the supply of wash liquid into the wash liquid tank 113 to escape, a further valve, not shown in FIG. 1, can at least temporarily open the pump-out line 115.
One aim of the present application is to dissolve the laundry care substance received in the laundry care substance receiver 121 not completely but only partially, so that a portion of the laundry care substance initially received in the laundry care substance receiver 121 can continue to be used in the laundry care substance receiver 121 after the dissolving step and during a subsequent washing step.
For this reason, the control device 127 is configured to: the pump 111 is activated during the dissolving step for pumping a partial fluid volume of fluid out of the wash chamber 101. The partial fluid quantity pumped out during the dissolving step is defined such that it is sufficient for dissolving at least a part of the laundry care substance received in the laundry care substance receptacle 121, but in particular does not completely dissolve the laundry care substance from the laundry care substance receptacle 121.
In order to limit the amount of partial fluid pumped out during the dissolving step, there are several alternative possibilities.
In particular, the laundry care appliance 100 has a pressure sensor, not shown in fig. 2, for detecting the air pressure in the laundry chamber 101, wherein the pressure sensor is connected in terms of control technology to the control device 127. The control device 127 is configured to: the partial fluid quantity pumped out by the pump 111 during the dissolving step is determined from the air pressure in the laundry chamber 101 detected by the pressure sensor.
In particular, the control device 127 is configured to: during the dissolving step, when the air pressure detected by the pressure sensor is below an air pressure threshold, the pump 111 is deactivated, so that the pump 111 has pumped out a precisely defined partial fluid volume until it is deactivated.
Alternatively, the control device 127 is configured in particular for: during the dissolving step, the pump 111 is deactivated when the drop in the air pressure detected by the pressure sensor within a defined time interval exceeds a gradient limit value, so that the pump 111 has pumped out a precisely defined partial fluid volume until it is deactivated.
In particular, the wash liquid tank 113 has at least one level sensor, not shown in fig. 2, for detecting the level of wash liquid in the wash liquid tank 113. The control device 127 is configured to: during the dissolution step, the pump 111 is deactivated when the liquid level detected by the liquid level sensor exceeds a liquid level threshold. Thus, the part of the fluid volume pumped by the pump 111 during the dissolution step corresponds to the difference between the fluid level and the fluid level threshold before the dissolution step.
The partial fluid quantity can be determined in particular as a function of the activation time of the pump 111 during the dissolution process, if the pump 111 is operated in particular at a constant rotational speed and thus pumps the fluid at a constant volume flow.
If the pump 111 is in particular designed as a variable-speed pump 111 and thus pumps fluid in a variable volumetric flow, the partial fluid quantity can be determined as a function of the rotational speed of the pump 111 during the dissolution process.
The respective optional possibilities for determining the partial fluid quantity pumped out of the laundry chamber 101 during the dissolving step may be combined arbitrarily and are not limiting.
The control device 127 is also designed in particular for: during a further dissolving step following the dissolving step, the pump 111 is activated for pumping a further partial fluid quantity of fluid out of the laundry chamber 101 in order to pump the further partial fluid quantity of fluid out of the laundry chamber 101 and into the wash liquor tank 113 via the laundry care substance receptacle 121 and to dissolve the laundry care substance received in the laundry care substance receptacle 121 at least partially in the further partial fluid quantity of fluid.
In particular, the control device 127 is configured to: the further dissolving step is repeated a plurality of times for activating the pump 111 during the further dissolving step for pumping a plurality of further partial fluid quantities of fluid out of the laundry chamber 101 for pumping the plurality of further partial fluid quantities of fluid from the laundry chamber 101 and via the laundry care substance receptacle 121 into the wash liquor tank 113 and for at least partially dissolving the laundry care substance received in the laundry care substance receptacle 121 in the plurality of further partial fluid quantities of fluid.
Thus, by means of the further dissolving step(s), the laundry care substance can be gradually dissolved in different partial fluid amounts in incremental steps and transferred into the wash liquor tank 113, whereby the amount of laundry care substance dissolved during the further dissolving step(s) can advantageously be set.
The determination of the further partial fluid quantity of the fluid pumped out during the further dissolving step can be carried out analogously to the determination of the partial fluid quantity of the fluid pumped out during the dissolving step.
Fig. 3 shows a perspective view of the laundry chamber of the laundry care appliance during the return step.
The schematic configuration of the laundry care appliance 100 shown in fig. 3 differs from the schematic configuration of the laundry care appliance 100 shown in fig. 1 and 2 only in that: another fluid conducting direction 133 of the fluid pumped by the pump 111 from the wash liquor storage tank 113 into the wash chamber 101 is shown by an arrow.
After the dissolving step (or another dissolving step) shown in fig. 2, at least a portion of the laundry care substance previously received in the laundry care substance receptacle 121 is received in the washing liquid inside the washing liquid tank 113 and can be used in a subsequent washing step for washing the laundry inside the laundry chamber 101.
For this purpose, the control device 127 is designed to: during the return step following the dissolution step and/or the further dissolution step, the pump 111 is activated for pumping wash liquid from the wash liquid tank 113 in order to pump a return amount of fluid from the wash liquid tank 113 into the wash chamber 101.
Here, the withdrawal amount may be determined based on the change in the liquid level of the washing liquid in the washing liquid tank 113 determined by the liquid level sensor (or by the activation time and/or the number of revolutions of the pump 111) similarly to the partial fluid amount illustrated in fig. 2.
After the return step, the washing liquid returned into the laundry chamber 101 can be used for the washing step (in particular the pre-washing step).
Since the laundry care substance remains in the laundry care substance receptacle 121 after the dissolving step, this remaining laundry care substance can be used in a further washing step (in particular a main washing step) after the washing step (in particular a pre-washing step).
Here, the control device 127 is configured to: during the dissolving step, which follows the return step, the pump 111 is activated for pumping out the dissolving amount of fluid from the laundry chamber 101, in order to pump the dissolving amount of fluid from the laundry chamber 101 and via the laundry care substance receptacle 121 into the wash liquor tank 113, and to dissolve the laundry care substance received in the laundry care substance receptacle 121 at least partially (in particular completely) in the fluid.
Even if the desolventizing step is not shown in fig. 3, reference is also made to the corresponding fluid direction 131 in fig. 2. The amount of desolventization may also be determined similarly to the partial fluid amount (or the further partial fluid amount) illustrated in fig. 2.
After the lysis step, the wash liquor can be pumped from the wash liquor tank 113 back into the wash chamber 101 according to fig. 3 and then be available for another wash step (in particular the main wash step).
Depending on the number of washing steps, the partial fluid quantity pumped through the laundry care substance receiver 121 during the dissolving step (or the quantity of the dishwashing liquid pumped through the laundry care substance receiver 121 during the dishwashing step) can be varied (in particular in a ratio of 1/3 to 2/3) in order to ensure that the quantity of laundry care substance is advantageously adapted both during the pre-washing step and during the main washing step.
After the dissolving step (or dissolving steps), the laundry care substance is (in particular completely) dissolved out of the laundry care substance receiver 121.
Fig. 4 shows a schematic representation of a method for dissolving laundry care substances in a laundry care appliance.
As a first method step, the method 200 comprises: the pump 111 is activated 201 by the control device 127 during the dissolving step for pumping out a partial fluid quantity of fluid from the laundry chamber 101 in order to pump said partial fluid quantity of fluid from the laundry chamber 101 and via the laundry care substance receptacle 121 into the wash liquor tank 113 and to dissolve the laundry care substance received in the laundry care substance receptacle 121 at least partially in said partial fluid quantity of fluid.
As an optional second method step, the method 200 comprises: the pump 111 is activated 203 by the control device 127 during the return step following the dissolving step and/or the further dissolving step for pumping washing liquid from the washing liquid tank 113 in order to pump a return amount of fluid from the washing liquid tank 113 into the wash chamber 101.
As an optional third method step, method 200 includes: during the dissolving step following the return step, the pump 111 is activated 209 by the control device 127 for pumping out a dissolving amount of fluid from the laundry chamber 101 in order to pump said dissolving amount of fluid from the laundry chamber 101 and via the laundry care substance receptacle 121 into the washing liquid tank 113 and to dissolve the laundry care substance received in the laundry care substance receptacle 121 at least partially (in particular completely) in the dissolving amount of the partial fluid amount.
