Definitions
- the invention relates to a method and a control unit for operating a cleaning device in a gentle cycle, as well as a cleaning device.
- Cleaning devices such as washing machines, are used in abundance in today's everyday life, both in the private and in the commercial sector. Since the items to be cleaned can react differently to influences such as temperatures, types of washing or also to cleaning agents, such cleaning devices have a large number of selectable cleaning programs. Such cleaning devices also generally have a drum in which ribs are arranged to circulate the cleaning solution and the items to be cleaned.
- EP 2 309048 A1 describes such a drum with at least one driver rib for a washing machine.
- the invention has the object of creating an improved method and an improved control unit for operating a cleaning device in a gentle cycle, as well as an improved cleaning device.
- the advantages that can be achieved with the invention include, in addition to an improved washing effect in, for example, gentle programs, a reduction in the risk of shrinkage of the items to be cleaned.
- the drum is arranged in the tub.
- An inside of a drum shell of the drum is also made smooth, apart from a plurality of knobs.
- the knobs are shaped in order to set the cleaning liquid in the drum into a wave movement during a cleaning process.
- the cleaning device has a feed unit for Feeding the cleaning liquid into the tub and a drive to set the drum in a rotary motion.
- the method includes a step of providing a feed signal to an interface to the feed unit, the feed signal causing a cleaning liquid to be fed into the tub until a predetermined target level is reached.
- the target level causes the textiles to float inside the drum.
- the method further comprises a step of providing a movement signal to an interface to the drive when the target fill level is reached in order to bring about the rotary movement of the drum.
- the method can be carried out, for example, in a cleaning device, preferably in a washing machine.
- the cleaning device can be designed to wash textiles.
- the cleaning liquid can, for example, be a mixture of water and a detergent, as is typically used in cleaning devices.
- the supply unit can comprise a valve for admitting liquid from an external supply line.
- the drive can comprise a motor which can drive the drum directly or, for example, a belt or a transmission.
- the drum can be referred to as a laundry drum and can be formed without ribs. 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%.
- 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 nub can be understood as a hump-like elevation on the inside of the drum.
- a nub can be shaped like a pyramid or a cone.
- a knob can have a circle or a regular polygon as its base.
- a nub can also be referred to as a structural element, bulge or mini driver.
- the rib-free design of the drum means that very sensitive textiles can be cleaned gently. As the textiles float up, the laundry can be prevented from falling and the wool from shrinking. In this way, for example, shrinkage of woolen fabrics can be avoided. Nevertheless, a good washing effect can be achieved. In addition, very long breaks, which last up to 2-3 minutes, can be dispensed with.
- the method can include a step of reading in a quantity signal via an interface to a quantity determination device, the quantity signal representing a quantity of the textiles. Furthermore, the method can comprise a step of determining the target fill level using the quantity signal.
- the quantity determination device can be in the form of a sensor, for example, which is designed to determine the quantity of textiles by means of weighing the textiles, by means of a mass inertia method or optically.
- the amount of Textiles can display a weight or a volume of the textiles.
- an amount of the cleaning liquid required for the cleaning process can thereby be precisely dosed.
- the target fill level can cause at least a lower third of the drum to be filled with the cleaning liquid.
- a safe floating of the textiles can thereby advantageously be achieved.
- the movement signal can be provided in the step of providing in order to bring about the rotary movement of the drum in a wave washing rhythm which is suitable for causing the wave movement of the cleaning liquid.
- the rotary movement can take place, for example, in at least one direction, but advantageously alternately also in a further direction opposite to the direction.
- the cleaning liquid can be set into a wave movement as quickly as possible.
- the wave washing rhythm can be suitable for causing the wave movement with a predetermined frequency of waves of the wave movement.
- the frequency of the waves can be selected as a function of a selected cleaning program or as a function of the textiles to be cleaned, so that the waves can be stronger or weaker, for example, and thus flow through the textiles to different degrees.
- the movement signal can be provided in the step of providing in order to bring about a movement frequency suitable for realizing the wave washing rhythm, a drum speed and additionally or alternatively a rotation pause value of the rotary movement.
- the movement frequency, the drum speed and additionally or alternatively the rotation pause value of the rotation movement can be changed in order to change the strength and the wave frequency of the cleaning liquid.
- the movement frequency, the drum speed and additionally or alternatively the rotation pause value can be set as a function of a selected cleaning program. Stored values can be accessed, which can be selected using a look-up table, for example.
- the step of providing the movement signal can be provided in order to bring about the rotational movement of the drum in a pendulum rhythm with successive rotations of the drum having increasing speeds without a complete revolution of the drum.
- the textiles are advantageously not moved through the drum as a result of the rotary movement with rapid change and with increasing amplitude, despite the rotating drum.
- the movement signal can effect the pendulum rhythm with a frequency between 0.1 Hz and 0.3 Hz.
- the movement signal can be provided in the step of providing in order to bring about the rotary movement of the drum for a predetermined period of time in one and the same direction.
- a period of time is selected to be at least long enough that a horizontal rotary movement of the textiles due to frictional contact of the textiles with a drum base of the drum can be achieved during a cleaning process.
- the horizontal rotary movement can be understood as a circular movement of the textiles. In this way, a thorough cleaning of the textiles can advantageously be achieved.
- the frictional contact is very gentle.
- the period of time can be at least five minutes.
- the supply signal can cause the cleaning liquid to be supplied until the predetermined target fill level is reached if a program signal indicates a selection of the gentle program by a user.
- the supply can cause the cleaning liquid to be supplied until a minimum level is reached, which is lower than the nominal level and prevents the floating of the textiles inside the drum (108) when the program signal indicates a selection of a normal program by the user. In this way, less sensitive textiles can be exposed to stronger mechanical loads in the normal 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 through this embodiment variant of the invention in the form of a control unit.
- 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, represent a sensor signal that can be read in via an input interface of the control unit.
- 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 control unit can use a logic circuit, a Integrated circuit or a software module and be implemented, for example, as a discrete component or encompassed by a discrete component.
- a computer program product or computer program with program code which can be stored on a machine-readable carrier or storage medium such as a semiconductor memory, a hard disk or an optical memory, is also advantageous. If the program product or program is executed on a computer or a control unit, the program product or program can be used to carry out, implement and / or control the steps of the method according to one of the embodiments described above.
- a cleaning device for cleaning textiles which has a tub for receiving cleaning liquid and a rotatable drum for receiving the textiles, which drum is arranged in the tub.
- An inside of a drum shell of the drum is designed to be smooth, apart from a plurality of knobs.
- the knobs are shaped in order to set the cleaning liquid in the drum into a wave movement during a cleaning process.
- the cleaning device has a feed unit for feeding the cleaning liquid into the tub, a drive for setting the drum in a rotary motion and a control unit in a variant mentioned above for controlling the feed unit and the drive in order to operate the cleaning device.
- the cleaning device can be implemented, for example, as a washing machine in which a method can be carried out in one of the variants mentioned above.
- the cleaning device can be implemented, for example, as a household device, but also as a professional device.
- the knobs can be shaped as so-called royal honeycombs.
- the knobs can be shaped as a dome-like curvature and can protrude into an interior of the drum. In this way, the knobs advantageously form a resistance for the cleaning liquid and additionally or alternatively for the textiles in order to set the cleaning liquid and additionally or alternatively the textiles in motion.

In short, the control unit 116 controls, for example, an admission of the cleaning liquid 106 to a target fill level 116 and a movement of the drum 108.
- a concept for a wave washing rhythm for very sensitive textiles 102 in a ribless drum 108 for the cleaning device 100 is presented.
- very sensitive textiles 102 such as, for example, wool or silk
- the textiles 102 are cleaned by a wave movement of the cleaning liquid 106 without mechanical stress flows through it, so that indirect washing by activating the free liquor - comparable to a wave pool, in which the strength and frequency of the waves can be varied using various setting parameters, such as a swing frequency, speed and / or pause times.
- FIG. 2 shows a schematic side view of a cleaning device 100 according to an exemplary embodiment.
- the cleaning device 100 can correspond or be similar to the cleaning device 100 described in FIG.
- the cleaning device 100 shown here also has the drum 108 arranged in the tub 104, the feed unit 110, the drive 112 and the control unit 116.

- the supply unit 302 is designed to provide a supply signal 308 to an interface to the supply unit 110.
- the feed signal 308 causes the cleaning liquid to be fed into the tub until a predetermined target fill level is reached, which causes the textiles to float inside the drum.
- the provision unit 302 is designed to provide a movement signal 310 to an interface to the drive 112 when the target fill level is reached in order to bring about the rotary movement of the drum.
- the target fill level causes at least a lower third of the drum to be filled with the cleaning liquid.
- the movement signal 310 furthermore optionally causes the rotary movement in a wave washing rhythm which is suitable for causing the wave movement of the cleaning liquid.
- the wave washing rhythm is optionally suitable for the To effect wave motion with a predetermined frequency of waves.
- the movement signal 310 provided by the supply unit 302 brings about a movement frequency suitable for realizing the wave washing rhythm, a drum speed and / or a rotation pause value of the rotary movement.
- the movement signal 310 causes the drum to rotate for a predetermined period of time in one and the same direction.
- the period of time is optionally selected to be at least so long that a horizontal rotary movement of the textiles is achieved during a cleaning process due to frictional contact of the textiles with a drum base of the drum.
- the duration is, for example, at least five minutes.
- the movement signal 310 causes the drum to rotate in a pendulum rhythm with successive rotations of the drum at increasing speeds, without a complete rotation of the drum taking place.

- the read-in unit 300 is designed to read in a program signal 320 via an interface to an input device 322 of the cleaning device.
- the program signal 320 indicates a program selection by a user. For example, if the program signal 320 indicates a selection of the gentle program, the feed signal 308 is determined in such a way that the cleaning liquid is fed up to the target fill level. If, on the other hand, the program signal 320 indicates a selection of a normal program, the feed signal 308 is determined according to one embodiment so that the cleaning liquid is fed up to a minimum fill level which is so low that the textiles do not float in the drum.

- a high water level which is also called Target level is designated, set.
- the textiles which are also referred to as laundry, float up in such a way that there is no direct contact between the textiles and the drum shell.
- the textiles to be washed are "artificially" suspended, so to speak, which means that the drum shell according to this exemplary embodiment does not result in any "hard” mechanical stress.
- the desired fill level depends on the amount of laundry detected in advance by means of the amount determining device 306.
- the amount of laundry is determined by various measures, such as inertia methods or weighing the textiles, for example at the start of the program.
- the cleaning liquid also referred to as washing liquor
- the cleaning liquid is set in wave motion by the corresponding wave washing rhythm and by the knobs, which are also referred to as structural elements.
- the laundry is not moved directly due to the lack of laundry carriers, the ribs, but rather flows through the "wave pool" so that the textiles are subjected to a massage. This process ensures an absolutely gentle textile treatment in connection with an improved washing effect. If there is no change of direction for a longer period of time with the wave washing rhythm, the textiles are additionally set in a horizontal rotary movement by a structure of the drum base according to this exemplary embodiment. This leads to a further mechanical flow.
- the wave washing rhythm is carried out like a pendulum rhythm, which means rapid changes with increasing amplitude, the laundry is not moved despite the rotating drum.
- these two processes can be varied depending on the program, amount of laundry and sensitivity.
- the wave washing rhythm presented here and the high water level result in increased washing mechanics for sensitive loads. This means faster washing and / or a higher washing effect is achieved.
- resources are saved at the same time due to the load-dependent target fill level. Due to the variable water level and the wave washing rhythm, optimal washing results are achieved even for small laundry loads of, for example, less than 0.5 kg of wool.
