Description

The present invention relates to a laundry care device with a control.

In a laundry care device with a pump-around system, washing liquid is pumped out of the tub by means of a pumping device, and the pumped-off washing liquid is again fed into the tub through the pumping system by means of the pumping device in order to wet the laundry in the laundry drum again with washing liquid. During the pumping over, the laundry drum is further rotated by a drum drive at a rotational speed in order to ensure an advantageous flow of laundry through the laundry drum. If the pumping is not coordinated with the rotation of the laundry drum, the flow of laundry through the pumping can possibly be impaired.

In the EP 2 918 721 A1 discloses a pump device for a washing machine or dishwasher, which has a controller for controlling an electric motor.

In the DE 42 10 577 A1 discloses a washing machine with a laundry drum, wherein during a spinning section the rinsed-off washing liquid can be returned to the laundry drum via an injection device.

The disclosure EP 2 781 640 A1 describes a washing machine.

The disclosure DE 10 2006 039 477 A1 describes a washing machine.

It is the object on which the invention is based to specify a laundry care device in which an effective laundry care process of the entire laundry is made possible.

This object is achieved by the objects with the features according to the independent claims. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

According to one aspect, the object according to the invention is achieved by a laundry care device with a tub for holding washing liquid, a laundry drum for holding laundry being arranged in the tub, wherein the tub comprises an outlet opening and an inlet nozzle, the outlet opening being fluidly connected to the inlet nozzle by a line, a pumping device for pumping washing liquid being arranged in the line, the pumping device being designed to pump washing liquid out of the tub through the outlet opening, and pumping the pumped washing liquid through the line and through the inlet nozzle back into the washing drum arranged in the tub to rewet the washing in the washing drum with washing liquid, a drum drive for rotating the washing drum and a controller for controlling the drum drive and the pumping device , wherein the controller is designed to control the drum drive during a rotation process in order to rotate the laundry drum at a rotational speed, wherein the controller is designed to activate the pumping device at the beginning of the rotation process n to pump washing liquid through the drain opening from the tub into the line, and to supply the pumped washing liquid through the line and through the inlet nozzle again to the laundry in the laundry drum, and wherein the controller is designed to deactivate the pumping device at the end of the rotation process .

This achieves the technical advantage that by activating the pumping device at the beginning of the rotation process and deactivating the pumping device at the end of the rotation process, a particularly effective coupling between the rotation of the laundry drum and the pumping of washing liquid in the laundry care device can be ensured. During a rotation of the washing drum, it is more effective to pump around since the washing liquid conveyed into the washing drum can be carried along by the rotating washing drum.

In conventional laundry care devices, the pumping process is not coordinated with the rotation of the laundry drum, whereby the pumping device often supplies washing liquid to the laundry in the washing drum when the washing drum is not rotating, and the pumping device often does not supply washing liquid to the laundry in the washing drum when the washing drum rotates . During a standstill phase of the laundry drum, under certain circumstances, in particular when the laundry drum is fully loaded, the washing liquid supplied may bounce off the laundry come, so that the supplied washing liquid does not wet the laundry, but flows directly into the tub on the outside of the laundry drum.

In the laundry care device according to the invention, the control only activates the pumping device at the beginning of the rotation process when the laundry drum is actively rotating. At the end of the rotation process, the pumping device is deactivated by the control, as a result of which the filling level of washing liquid in the tub can regenerate, and the pumping device is provided with a sufficient amount of washing liquid in a subsequent rotation process in order to pump washing liquid again. In this way, performance optimization of the pumping process in the laundry care device can be ensured, and the on-time of the pumping device becomes more reproducible.

A laundry care device is understood to mean a device which is used for laundry care, such as a washing machine or dryer. In particular, such a laundry care device is understood to mean a household laundry care device. So a laundry care device, which is used in the context of housekeeping, and with which laundry is treated in normal household quantities.

In an advantageous embodiment of the laundry care device, the controller is designed to deactivate the pumping device at a deactivation point in time before the end of the rotation process, or the controller is designed to operate the pumping device at the deactivation point of time with a pumping power which is insufficient for the pumped-off washing liquid feed the laundry again in the laundry drum.

This has the technical advantage that deactivating the pumping device or reducing the pumping capacity of the pumping device at the time of deactivation ensures timely deactivation of the pumping device at the end of the rotation process. The deactivation time is before the end of the rotation process and provides a time buffer. Since after the deactivation of the pumping device a reduction in the delivery flow of the pumped washing liquid does not occur immediately, but under certain circumstances with a time delay, it can thus be ensured by the time buffer be that at the end of the rotation process, no washing liquid is fed through the inlet nozzle of the laundry in the laundry drum.

In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the laundry drum during the rotation process in a first direction of rotation or in a second direction of rotation, which is opposite to the first direction of rotation.

This achieves the technical advantage that a particularly advantageous turning of the laundry in the laundry drum is ensured by rotating the laundry drum in different directions of rotation, and thus also an advantageous wetting of the laundry in the laundry drum is made possible.

In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the laundry drum in the first direction of rotation during the rotation process, and the drum drive is designed to rotate the laundry drum in the second direction of rotation during a further rotation process following the rotation process.

This achieves the technical advantage that by rotating the laundry drum in alternating directions of rotation during successive rotation processes, a particularly advantageous dampening of the laundry during the pumping process is ensured.

In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the laundry drum during the rotation process at a turning rotation speed in order to turn the laundry in the washing drum, the turning rotation speed in particular comprising 20 revolutions per minute to 60 revolutions per minute.

This has the technical advantage that the rotation rotation speed ensures a sufficient rotational movement of the laundry drum in order to effectively turn the laundry in the laundry drum. This can ensure an advantageous flooding of the laundry during pumping.

In a further advantageous embodiment of the laundry care device, the drum drive is designed to rotate the laundry drum during the rotation process at an attachment rotation speed in order to bring the laundry into contact with the laundry drum, the attachment rotation speed comprising in particular 60 revolutions per minute to 300 revolutions per minute.

This achieves the technical advantage that an accelerated rotational movement of the laundry drum is ensured by the system rotation speed, which is sufficient for the laundry to be brought into contact with the laundry drum. As a result, a laundry channel forms in the interior of the laundry in the laundry drum, into which washing liquid is introduced by means of the inlet nozzle in order to advantageously wet the laundry with the washing liquid. Due to the centrifugal force acting on it, the washing liquid introduced into the laundry channel is pressed outwards by the laundry lying against the laundry drum and thus ensures an advantageous wetting of the laundry.

According to the invention, the control is designed to repeat the rotation process several times, in particular to repeat it between 100 and 600 times.

The technical advantage is thereby achieved that particularly repetitive moistening of the laundry in the laundry drum is ensured by repeating the rotation process several times.

According to the invention, there is a rotation pause between the repeated rotation processes, the controller being designed to deactivate the drum drive and the pumping device during the respective rotation pause.

This achieves the technical advantage that by deactivating the drum drive and the pumping device during the pauses in rotation it can be ensured that there is an increase in the washing liquid level in the tub, which means that the pumping device in one on the Rotation break following wash cycle again a sufficient amount of washing liquid is available for the pumping process.

According to the invention, the laundry care device comprises a program selection device for selecting a multiplicity of selectable laundry care programs, the controller being designed to control the duration of the rotation breaks as a function of the selected laundry care program.

This has the technical advantage that the duration of the rotation breaks can be advantageously adapted to the selected laundry care program. If, for example, a wool washing program has been selected for the maintenance of laundry made of wool, the duration of the rotation breaks can be increased, because wool has an increased retention capacity of washing liquid.

In a further advantageous embodiment of the laundry care device, the laundry care device has a fill level sensor for detecting a fill level of wash liquid in the tub, the controller being designed to start the rotation process and to activate the drum drive and the pumping device at the start of the rotation process when the detected fill level exceeds a level threshold.

This achieves the technical advantage that it can be ensured that the level of the washing liquid in the suds container exceeds the fill level threshold, so that there is a sufficient amount of washing liquid in the suds container so that an advantageous pumping around of the washing liquid can be ensured by the pumping device.

In a further advantageous embodiment of the laundry care device, the laundry care device has a power detection element for detecting an electrical power value of the pumping device, the controller being designed to end the rotation process and the drum drive and the pumping device on Deactivate at the end of the rotation process if the detected electrical power value falls below an electrical power threshold value.

This achieves the technical advantage that the control system can recognize when the electrical power value of the pumping device falls below the electrical power threshold value when air is sucked in by the pumping device and thus there is no more washing liquid in the tub. This is made possible because when pumping washing liquid through the pumping device, a larger electrical output value of the pumping device is required compared to pumping an air-washing liquid mixture. This can prevent air from being pumped through the pumping device.

In a further advantageous embodiment of the laundry care device, the electrical power detection element comprises a current sensor for detecting a supply current of the pumping device.

This achieves the technical advantage that the current sensor for detecting a supply current of the pumping device can effectively detect when the pumping device sucks in an air / washing liquid mixture and the rotation process can thereby be ended.

In a further advantageous embodiment of the laundry care device, a number of projections are arranged in the laundry drum which are designed to move the laundry in the laundry drum while the laundry drum is rotating.

This achieves the technical advantage that the projections can be used to ensure that the laundry is advantageously turned or taken along in the laundry drum during the rotation process.

According to a second aspect of the invention, the object is achieved by a method for washing laundry in a laundry care device, the laundry care device having a tub for holding washing liquid, a laundry drum for holding laundry being arranged in the tub the tub comprises an outlet opening and an inlet nozzle, the outlet opening being fluidly connected to the inlet nozzle by a line, a pumping device for pumping washing liquid being arranged in the line, the pumping device being designed to pump washing liquid out of the tub through the outlet opening, and pumping the pumped washing liquid through the line and through the inlet nozzle back into the washing drum arranged in the tub to rewet the washing in the washing drum with washing liquid, the laundry care device comprising a drum drive for rotating the washing drum and a controller for controlling the drum drive and the pump-around device, the method comprising the following steps, activating the drum drive during a rotation process by the controller in order to rotate the laundry drum at a rotational speed, activating the pump-around device g at the beginning of the rotation process by the controller in order to pump washing liquid through the drain opening from the tub into the line and to feed the pumped washing liquid through the line and through the inlet nozzle again to the laundry in the washing drum, and deactivating the pumping device at the end of the rotation process through the controller.

This achieves the technical advantage that the method ensures particularly effective wetting of laundry in the laundry drum while washing liquid is being pumped around.

In a further advantageous embodiment of the method, the rotation process is repeated several times by the control.

This achieves the technical advantage that, by repeating the rotation process several times, a particularly effective pumping of washing liquid in the laundry care device is ensured by the control.

is a schematic representation of a method for washing laundry in a laundry care device.

Fig. 1 shows a schematic view of a general laundry care appliance 100, such as a washing machine. The laundry care appliance 100 comprises a induction bowl 101, into which detergents or other liquid substances can be filled. The laundry care device 100 comprises a door 103 for loading the laundry care device 100 with laundry.

Fig. 2 shows a schematic view of a pumping system of a laundry care device with a pumping device. The laundry care device 100 has a tub 105 for holding washing liquid and has a laundry drum 107 for holding laundry. The laundry drum 107 has a drum underside 109 and is driven by a drum drive 111 by means of a drive connection 113. The tub 105 has an outlet opening 115 and an inlet nozzle 117, which are fluidically connected by a line 119 of the pumping system, a pumping device 121 for pumping washing liquid through the line 119 being arranged in the line 119. The pumping device 121 can wash liquid through the drain opening 115 from the tub 105 during a Fig. 2 Pump the pumping process (not shown) into line 119 and feed the pumped-out washing liquid through line 119 and through the inlet nozzle 117 of the washing drum 107 again. As a result, the fresh washing liquid can be effectively pumped through line 119 during a laundry care process the laundry in the laundry drum 107 are fed again. As a result, the laundry care success can be improved during a laundry care process.

The laundry care device 100 further comprises a controller 123 which is connected to the pumping device 121 by a first control connection 125 and which is connected to the drum drive 111 by a second control connection 127 in order to control the pumping device 121 and the drum drive 111. The controller 123 is designed to activate the drum drive 111 at the start of a rotation process and to activate the pumping device 121 at the start of the rotation process.

Fig. 3 shows a graphical representation of a washing process in a laundry care device according to an embodiment. Fig. 3 shows a temporal representation of the filling level of washing liquid in the tub 105, the rotational speed of the washing drum 107, and the pumping power of the pumping device 121, all of which are plotted along the ordinate axis 129 as a function of the time which is indicated along the abscissa axis 131.

The first curve 133 shows the course of the filling level of washing liquid in the tub 105. The second curve 135 shows the course of the rotational speed of the laundry drum 107. The third curve 137 shows the course of the pumping power of the pumping device 121.

As shown in the second curve 135, the drum drive 111 is deactivated before the pumping begins and the laundry drum 107 has a standstill rotational speed 139 of 0 revolutions per minute. As shown in the third curve 137, the pumping device 121 is likewise deactivated before the pumping begins and has a standstill pump output 141. As shown in the first curve 133, the filling level of the washing liquid in the tub 105 has a maximum value before pumping over.

The controller 123 is designed to activate the drum drive 111 and the pumping device 121 when the fill level of the washing liquid present in the tub 105 is above an activation point 143.

By activating the drum drive 111 and the pumping device 121, the rotation process 145 is started by the controller 123. During the rotation process 145, the drum drive 111 rotates the laundry drum 107 at a rotation speed 147. At the beginning of the rotation process 145, the controller 123 activates the pumping device 121, which pumps pumped washing liquid with a pumping power 149 in the laundry care device 100. The pumping device 121 pumps a quantity of washing liquid from the tub 105 into the line 119 during the rotation process 145 and feeds the pumped-out washing liquid through the line 119 and through the inlet nozzle 117 to the laundry in the laundry drum 107 again. As a result, the fill level of the washing liquid present in the tub 105 drops and falls below a switch-off point 151 during the rotation process 145. When the switch-off point 151 is undershot, an air / washing liquid mixture is drawn in by the pumping device 121, which can be detected by the controller 123, and what the rotation process 145 can be ended by the controller 123.

At the end of the rotation process 145, the controller 123 deactivates the drum drive 111 and the pumping device 121. After the end of the rotation process 145, the laundry drum 107 again has a standstill rotational speed 139 of 0 revolutions per minute and the pumping device 121 again has a standstill pumping power 141.

In this case, the controller 123 is designed to repeat the rotation process 145 several times, with 145 pauses in rotation 153 being present between the individual rotation processes. During the individual rotation processes 145, the drum drive 111 can rotate the laundry drum 107 in a first direction of rotation or alternatively in a further direction of rotation opposite to the first direction of rotation.

Like in the Fig. 3 is shown, the drum drive 111 is designed to rotate the laundry drum 107 at an attachment rotation speed 155 during the fifth rotation process 145 in order to bring the laundry into contact with the laundry drum 107. The investment rotation speed 155 is greater than the rotation speed 147 during the preceding rotation processes 145 and, by the fact that the laundry rests on the laundry drum 107, enables particularly effective moistening of the laundry with washing liquid during pumping.

Thus, the controller 123 is designed during the standstill of the laundry drum 107 during the laundry care program not to pump the washing liquid and to activate the pumping device 121 only when the laundry drum 107 is rotated by the drum drive 111 and a positive effect for the washing result can be achieved. The pumping device 121 is activated simultaneously with the activation of the drum drive 111. If the rotational movement of the laundry drum 107 stops, the pumping device 121 is also deactivated at the same time. The switch-on and switch-off times can then be programmed on a higher level in relation to the total washing time of the laundry care program.

A further implementation enables the controller 123 to recognize when the rotation process 145 of the laundry drum 107 will end. In this case, the controller 123 can already deactivate the pumping device 121 at a deactivation point in time before the end of the rotation process 145, or reduce the pumping capacity of the pumping device 121 to such an extent that there is not a sufficient delivery flow for the pumped-off washing liquid to again wash the laundry in the washing drum 107 feed.

In the respective rotation pauses 153 between the individual rotation processes, the level of the volume of the washing liquid pumped around in the pumping system can regenerate. As a result, the pumping device 121 is able to maintain the delivery flow of the washing liquid for longer in the subsequent rotation process 145. In a washing program with a duration of 3.5 hours, up to 400 pauses in rotation 153 occur and there is therefore great potential to stabilize the pumping cycle.

The control according to the invention enables the pumping device 121 to be switched on for a long period, which leads to better results in the washing performance. In addition, the duty cycle of the pumping device 121 becomes more reproducible. The level of the washing liquid always recovers when the Pumping device 121 cannot pump pumping washing liquid effectively. This results in an overall performance optimization of the pumping device 121.

Fig. 4 shows a schematic representation of a method 200 for washing laundry in a laundry care appliance 100, which according to the embodiments of FIGS Fig. 2 and Fig. 3 is described.

The method 200 includes the control 201 of the drum drive 111 during a rotation process 145 by the controller 123 in order to rotate the laundry drum 107 at a rotation speed 147. The method 200 includes activating 203 the pumping device 121 at the beginning of the rotation process 145 by the controller 123 in order to pump washing liquid through the drain opening 115 from the tub 105 into the line 119, and the pumped-off washing liquid through the line 119 and through the inlet nozzle 117 feed the laundry again in the laundry drum 107. The method 200 includes the deactivation 205 of the pumping device 121 at the end of the rotation process 145 by the controller 123.

All of the features explained and shown in connection with individual embodiments of the invention can be provided in different combinations in the subject matter of the invention in order to simultaneously realize their advantageous effects.

The scope 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.
