Definitions
- the invention relates to a method and a control unit for operating a cleaning device for the pretreatment and main treatment of textiles, as well as a cleaning device.
- EP 2 309048 A1 describes a drum for a washing machine with at least one driver rib which is attached to a drum shell.
- the approach presented here has the task of creating an improved method and an improved control unit for operating a cleaning device for the pretreatment and main treatment of textiles, as well as an improved cleaning device.
- this object is achieved by a method and a control unit for operating a cleaning device for the pretreatment and main treatment of textiles and by a cleaning device with the features of the main claims.
- the cleaning device has a rotatable, ribless drum for receiving the textiles, which drum can be closed with a drum door and has a drum shell and at least one honeycomb.
- the method comprises a step of providing a feed signal to an interface to a feed unit of the cleaning device, the feed signal causing a cleaning liquid to be fed into a tub of the cleaning device until a predetermined initial level is reached, the one between the drum shell and an upper edge of the honeycomb Represents the liquid level of the cleaning liquid.
- a saturation action is carried out in order to bring about saturation of the textiles to be pretreated with the cleaning liquid.
- the method further comprises a step of reading in a level signal which represents a level of the cleaning liquid.
- the method optionally comprises a step of repeating the step of providing the feed signal and the step of Carrying out the saturation action until the fill level signal represents a fill level of the cleaning liquid indicating saturation of the textiles to be pretreated , until a target fill level is reached which represents a liquid level of the cleaning liquid which is above the predetermined initial fill level and at which the textiles to be pretreated can slide in the drum.
- the method further comprises a step of providing a movement signal to an interface to a drive of the cleaning device, which causes a pendulum rhythm of the drum for pretreating the textiles to be pretreated. In an unlocking step, the drum door is unlocked after the textiles to be pretreated have been pretreated, in order to enable additional textiles to be added for a main treatment of the textiles.
- the method can be carried out, for example, in a commercially available cleaning device, which can be implemented as a washing machine, for example.
- the pretreatment can also be referred to as a washboard function and the main treatment can be referred to as a normal washing program.
- the drum can be referred to as a washing drum or laundry drum and can be rotated in two opposite directions.
- the drum door can for example be arranged on a front of the cleaning device so that it is advantageously easily accessible for a user and thereby simplifies a loading process by the user.
- the drum shell can be shaped as a circumferential side wall of the drum.
- the initial filling level can be selected such that a cavity formed by the honeycomb is not completely filled with cleaning fluid when the honeycomb is oriented vertically downwards.
- an inside of the drum can be slightly wetted at the initial fill level.
- the honeycomb can be implemented, for example, as a surface structure of the drum shell protruding into the interior of the drum. Ribless can mean that the drum does not have a rib on the inside which extends between the drum base and the drum opening, for example parallel to the axis of rotation of the drum.
- a honeycomb can be understood as a hump-like elevation on the inside of the drum.
- a honeycomb can be shaped like a pyramid or a cone.
- a honeycomb can have a circle or a regular polygon as its base.
- a honeycomb can also be referred to as a structural element, cube or mini-carrier.
- a drum without ribs is used, for example, if the drum does not contain any geometry protruding from the surface where the drum radius is reduced by more than 10%.
- the feed unit can be designed as a valve, for example.
- the cleaning liquid can be, for example, water, which can additionally or alternatively be mixed with a detergent.
- the saturation action can, for example, be a Wait and then include a slight twist or a flood.
- the step of repeating can then be carried out when the fabrics are not yet sufficiently saturated. In such a case, the textiles can soak up cleaning liquid so that the level falls below the initial level.
- the drive can comprise an electric motor and cause the movements of the drum.
- the drum can be moved when the target level is reached, for example to simulate a washboard function.
- the pendulum rhythm advantageously describes a back and forth movement of the drum in two opposite directions.
- the unlocking step advantageously represents an end of the pretreatment, so that the user can advantageously add more textiles to the cleaning device.
- a main wash cycle can then be carried out, for example.
- the pretreatment of individual stained textiles can advantageously be carried out automatically by the cleaning device in the form of a pretreatment phase, which saves the user a great deal of time compared to manual activities.
- various process parameters can be intelligently matched to mechanical pretreatment with exact positioning of stained textiles in the drum.
- Such process parameters relate, for example, to the level of the cleaning liquid or the characteristic of the rotation of the drum.
- This can advantageously be carried out in connection with washing drums without laundry carriers, that is to say for example ribs.
- Process-related settings can be made by selecting various options, for example washing rhythms can be adjusted.
- washing rhythms that differ in the washing speed, in the geometric shape of the speed, for example in the form of a rectangle or a ramp, and in the speed frequency.
- An intelligent adaptation of the washing rhythm to increased mechanical requirements in the pretreatment process e.g. depending on the stains or the degree of soiling, in interaction with other process parameters such as water level, flooding or saturation, enables optimal pretreatment in the sense of a washboard function.
- stains that are to be removed mechanically whereby the mechanics refer to the washing rhythm
- complete removal of the stain in the pretreatment phase stains, prewash, soaking
- This enables targeted mechanical treatment of the stained textile area.
- the pretreatment process does not affect the entire batch of laundry, since textiles that are not to be pretreated can be refilled after the pretreatment and therefore not through the Pretreatment are charged. This prevents even less soiled textiles from being washed for a long time and subjected to high mechanical loads.
- the step of performing the saturation action can include a step of providing a further movement signal to the interface to the drive of the cleaning device, wherein the further movement signal can cause rotary movements of the drum in a rocking rhythm to saturate the textiles to be pretreated with the cleaning fluid.
- the further movement signal can be provided, for example, when the initial fill level is reached.
- the rocking rhythm can, for example, refer to a back and forth movement of the drum in two opposite directions, in which a rate of rotation can be kept low.
- the textiles can advantageously be moved in the drum in such a way that a period of time for saturating the textiles can be reduced.
- the rotary movements of the drum can then be stopped.
- the step of performing the saturation action can include a step of providing a flooding signal to an interface to a flooding device of the cleaning device, the flooding signal being able to cause the cleaning liquid to flood around to saturate the textiles to be pretreated with the cleaning liquid.
- the flooding device can, for example, comprise a pump, by means of which cleaning liquid can be conveyed from the tub to the textiles.
- the duration of the pretreatment program can be shortened as a result, since saturation can be reached quickly.
- the pendulum rhythm in the step of providing the movement signal, can define successive and increasing rotational speeds of the drum without a complete revolution of the drum until a final rotational speed of the pendulum rhythm is reached. In this way, stubborn soiling of the textiles can also advantageously be removed.
- the method can comprise a step of providing a stop signal for terminating the rotational movements of the drum when the final rotational speed is reached.
- this can prevent the textiles from resting too strongly on the drum shell, for example.
- the movement signal in the step of providing the movement signal, can bring about the pendulum rhythm with a frequency between 0.1 Hz and 0.3 Hz. In this way, a slight rubbing movement of the textiles on the drum shell can advantageously be realized, so that, for example, a stain is treated like a washboard.
- the movement signal in the step of providing the movement signal, can cause successive rotary movements with an increase in rotational speed between 4 rpm and 6 rpm.
- the final speed in the step of providing the movement signal, can be between 50 rpm and 70 rpm. A particularly thorough pretreatment can advantageously be implemented in this way.
- the method can include a step of providing a heating signal to an interface to a heating device of the cleaning device during the step of providing the movement signal, wherein the heating signal can cause the cleaning liquid to be warmed up. This can increase the cleaning effect.
- the method can further include a step of reading in a locking signal after the unlocking step and a step of providing a subsequent movement signal to the interface to the drive of the cleaning device when the locking signal indicates a locked state of the drum door.
- the following movement signal can cause rotary movements of the drum in a main treatment rhythm to effect the main treatment of the textiles.
- the main treatment can, for example, be a customary washing program of the cleaning device, which can advantageously be carried out after the pretreatment.
- the user can advantageously be given the option of adding further textiles which, for example, have a lower degree of soiling than the textiles to be pretreated.
- the drum door can be locked after reloading, so that during the main treatment, for example, no cleaning liquid escapes to the outside of the cleaning device.
- the main treatment rhythm can include the pendulum rhythm of the drum.
- the pendulum rhythm can advantageously be used in a spin program.
- the approach presented here also creates a control unit which is designed to carry out, control or implement the steps of a variant of a method presented here in corresponding devices.
- the object on which the invention is based can also be achieved quickly and efficiently by means of this embodiment variant of the invention in the form of a device.
- the control unit can be designed to read in input signals and to determine and provide output signals using the input signals.
- An input signal can, for example, be sent via an input interface of the control unit represent readable sensor signal.
- An output signal can represent a control signal or a data signal that can be provided at an output interface of the control unit.
- the control unit can be designed to determine the output signals using a processing rule implemented in hardware or software.

- the feed signal 310 causes the cleaning liquid to be fed into the tub of the cleaning device until a predetermined initial fill level is reached, which represents a cleaning liquid level between the drum shell and the honeycomb.
- the initial filling level is selected such that a cavity formed by the honeycomb is not completely filled by the cleaning liquid when the drum is rotated so that the honeycomb is at the lowest point of the drum.
- the upper edge of the honeycomb located below that is to say the section of the honeycomb located below that protrudes furthest into the interior of the drum, protrudes from the cleaning liquid.
- the supply unit 302 continues designed to provide a further feed signal 314 to the interface to the feed unit 114.
- the further supply signal 314 causes a further supply of cleaning liquid into the tub until a target fill level is reached, which represents a liquid level of the cleaning liquid above the predetermined initial fill level.
- the supply unit 302 provides a movement signal 316 to an interface to a drive 110 of the cleaning device, which causes a pendulum rhythm of the drum for pretreating the textiles to be pretreated.
- the provision unit 302 is designed to provide an unlocking signal 320 for unlocking the drum door after the pretreatment of the textiles to be pretreated, which enables a user to optionally add further textiles for a main treatment of the textiles.
- the fact that textiles have been added is recognized, for example, by the fact that the locking signal 308 indicates a locked state of the drum door 116.
- the supply unit 302 is designed to provide a subsequent movement signal 309 to the interface to the drive 110 of the cleaning device after the optional reloading of further textiles, which causes rotary movements of the drum in a main treatment rhythm to effect the main treatment of the textiles.
- the provision unit 302 is only optionally designed to provide a stop signal 322 for terminating the rotary movements of the drum when the final rotational speed is reached.
- the supply unit 302 is optionally designed to provide a further movement signal 323 which, according to this exemplary embodiment, causes rotary movements of the drum in a rocking rhythm to saturate the textiles to be pretreated with the cleaning liquid.
- the supply unit is designed to provide a flooding signal 328 to an interface to a flooding device 330, the flooding signal 328 causing the cleaning liquid to flood to saturate the textiles to be pretreated with the cleaning liquid.
- the bypass device 330 comprises, for example, a pump.
- the provision unit 302 is optionally designed to provide a heating signal 324 to an interface to a heating device 326 of the cleaning device.
- the heating signal 324 according to this exemplary embodiment causes the cleaning liquid to be warmed up.
- cleaning liquid is first filled in using the feed signal 310 until the textiles to be pretreated are saturated.
- This process can be accomplished by deploying the further movement signal 323 for easy rotation of the drum and / or accelerated by the flooding signal 328.
- a level of the cleaning liquid in the tub is increased using the further feed signal 314 until the target fill level is reached.
- the target fill level can be firmly predetermined or, for example, can be set as a function of a quantity of the textile or textiles to be pretreated.
- the drum is then set into the pendulum rhythm using the movement signal 316, which enables the pretreatment with a clear mechanical component.
- the target level is selected so that the textiles in the drum can slide along the drum shell when the drum is rotated.
- the target fill level is selected in such a way that the textiles do not float up.
- the textiles to be pretreated are placed in the drum with the side to be pretreated pointing downwards.
- the drum door can be unlocked using the unlocking signal 320. This gives the user the option of placing additional textiles in the drum.
- the main treatment of the textiles can then be carried out. For this purpose, the level of the cleaning liquid can be adjusted if necessary.
- the drum can be rotated in a main treatment rhythm using the following movement signal.
- the approach presented here creates a possibility of enabling a washboard function in a rib-less drum, which is also referred to as a washing drum, as a pretreatment method. It makes sense to place the textile with the stain to be treated in the cleaning device, which is also known as a washing machine, so that the stain rests on the drum shell.
- the level of the cleaning liquid and a characteristic of the rotational movement of the drum are selected during the pretreatment according to one embodiment so that the textile is not rotated during the pretreatment.
- the textile to be pretreated is ideal for the downstream washing process, which is referred to here as the main treatment, through an intelligent interplay between drum movement, saturation, filling level, flooding, heating method and / or structural element, which is referred to here as a honeycomb and alternatively can also be referred to as a royal honeycomb.
- This upstream method which is referred to here as pretreatment, is comparable to a "washboard principle" as we know it from the early days of washing.
- the textile to be treated is placed in the drum with the stained side down.
- the initial fill level is set so that it is between the drum shell and the upper edge of the structure element of the honeycomb. It is necessary that the textile is 100% saturated. According to this exemplary embodiment, this state is achieved by a minimal rocking movement of the drum by suction through the textiles and / or by targeted activation of the flooding.
- a water level which is also referred to as the liquid level, is set between the textile and the drum shell, which enables the textile to slide.
- the saturated textile and the precisely set water level enable the 'washboard function', where a washboard function is generated using special rhythms.
- the washing rhythm which is also referred to here as the pendulum rhythm
- the pendulum rhythm is also defined by the frequency of, for example, 0.2 Hz, the final speed of, for example, a maximum of 60 rpm and the increase in speed per cycle of, for example, 5 rpm.
- the washboard function represents a frequent cleaning process, which corresponds to the original washboard philosophy and suggests an increase in the mechanical washing components.
- a treatment is carried out, for example, with or without the use of heating.
- FIG. 4 shows a flow chart of a method 400 for operating a cleaning device for the pretreatment and main treatment of textiles according to an exemplary embodiment.
- the method 400 can be carried out, for example, by a control unit, as was described in FIG. 3.
- the control unit can be used in a cleaning device with a drum without ribs, as was described in FIG.
- the method 400 comprises a step 402 of providing a feed signal to an interface to a feed unit of the cleaning device, the feed signal causing the cleaning liquid to be fed into the tub of the cleaning device, to a predetermined initial fill level is reached, which represents a liquid level of the cleaning liquid lying between the drum shell and the honeycomb.
- the method 400 further comprises a step 404 of carrying out a saturation action in order to bring about saturation of textiles to be pretreated with the cleaning liquid.
- the saturation action only represents a waiting time that allows cleaning fluid to be sucked up by the at least one textile to be pretreated.
- a fill level signal is read in, which represents a fill level of the cleaning fluid.
- Step 402 of providing the feed signal and step 404 of carrying out the saturation action are optionally repeated until the fill level signal represents a fill level of the cleaning liquid indicating saturation of the textiles to be pretreated.
- a further supply signal is provided to the interface to the supply unit of the cleaning device in a step 408 of providing, the further supply signal causing the cleaning liquid to be supplied into the tub of the cleaning device until a target level is reached, which is one above the predetermined Initial filling level represents the liquid level of the cleaning liquid and allows the at least one textile to be pretreated to slide in the drum.
- the method 400 comprises a step 410 of providing a movement signal to an interface to a drive of the cleaning device, which causes a pendulum rhythm of the drum for pretreating the textiles to be pretreated.
- the pendulum rhythm defines successive rotary movements of the drum with increasing speeds without a complete rotation of the drum.
- the rotations which have opposite directions of rotation, are repeated alternately until a final speed of the pendulum rhythm is reached.
- the movement signal causes the pendulum rhythm with a frequency between 0.1 Hz and 0.3 Hz and successive rotary movements with an increase in speed between 4 rpm and 6 rpm.
- the final speed is between 50 rpm and 70 rpm.
- a drum door is unlocked after the pretreatment in order to enable additional textiles to be added for a main treatment of both the at least one pretreated textile and the optionally added textiles. It is also possible to check the effect of the pretreatment and, if necessary, to restart it before the main treatment is carried out.
- the step 404 of performing the saturation action comprises a step of providing a further movement signal to the Interface to the drive of the cleaning device, the further movement signal causing rotary movements of the drum in a rocking rhythm to saturate the textiles to be pretreated with the cleaning liquid.
- step 404 of performing the saturation action comprises a step of providing a flooding signal at an interface to the flooding device.
- the flooding signal causes the cleaning liquid to flood in order to saturate the textiles to be pretreated with the cleaning liquid.
- the method 400 optionally includes a step 414 of outputting a heating signal to an interface to a heating device of the cleaning device.
- the heating signal causes the cleaning liquid to be warmed up.
- the method 400 further optionally comprises a step 416 of providing a stop signal for ending the rotational movements of the drum when the final rotational speed is reached.
- the method 400 further comprises a step 418 of reading in a
- the main treatment rhythm includes the pendulum rhythm of the drum.
