Definitions
- the invention relates to a device for mounting on an inner circumferential surface of a washing machine drum, comprising a housing, a voltage source and at least one electrode connected to the positive pole of the voltage source and acting as an anode, the device being suitable for converting a mediator species into a bleach-active species by means of electrolysis to activate.
- a mediator species is understood to mean a substance which is bleach-active in the activated, i.e. oxidized, state. In this state it is also known as a bleach-active species.
- the invention is in the field of washing machine technology, in particular in the field of household washing machines.
- a lot of soiling that is relevant to everyday life cannot be removed adequately from textiles using commercially available detergents.
- Oxidation of the delocalized p-electron system causes the dye to lose its ability to absorb light in the visual spectral range and thus appears colorless. In addition, in some cases the dye can break down into smaller and more water-soluble species.
- bleach systems are typically used for this purpose which contain a combination of tetraacetylethylenediamine (TAED) and bleaching agents such as sodium perborate or sodium perborate, with TAED acting as an activator of the bleaching agent.
- TAED tetraacetylethylenediamine
- bleaching agents such as sodium perborate or sodium perborate
- Liquid detergents On the other hand, often contain ingredients such as enzymes, dyes and fragrances, which in turn can be attacked and damaged by bleach. This makes it difficult to develop a liquid detergent suitable for domestic use with a potent bleaching effect.
- EP 31 34 500 B1 discloses the use of certain organic mediator compounds to enhance the cleaning performance of detergents and cleaning agents against soiling, washing or cleaning processes using bleach-active species produced from such mediator compounds, and detergents and cleaning agents which contain the mediator compound.
- the device according to the invention comprises a housing, a voltage source and at least one electrode connected to the positive pole of the voltage source and acting as an anode, wherein the device can be flowed through by a wash liquor and at least one inlet for introducing wash liquor into the device and at least comprises an outlet for discharging washing liquor from the device.
- the device is characterized in that the at least one inlet and the at least one outlet are arranged on the device in such a way that, when the device is in use, they lie directly above the inner circumferential surface of the washing machine drum and that the at least one inlet lies in a plane whose When the device is in use, the surface normal extends essentially orthogonally to the axis of rotation of the washing machine drum and that the at least one electrode is arranged within the device in such a way that its longitudinal extent extends essentially parallel to the surface normal of the plane in which the at least one inlet lies.
- the invention is a device which is provided and suitable for being mounted on an inner peripheral surface of a washing machine drum.
- it can be retrofitted in existing washing machines.
- a normal household washing machine can thus be retrofitted in a simple manner with the device according to the invention without further modifications or adaptations.
- the inner circumferential surface of a washing machine drum is understood to mean the circumferential surface of a washing machine drum facing the laundry to be washed.
- the at least one electrode generally has a length, a width and a height extension.
- the longitudinal extension of the at least one electrode is understood to mean the longest of these three dimensions.
- the device according to the invention comprises its own voltage source and at least one electrode connected to the positive pole of the voltage source and acting as an anode.
- the mediator molecules On the surface of this anode, when a washing liquor containing a mediator species flows through the device, the mediator molecules are oxidized.
- the mediator molecules thus oxidized and thus activated are bleach-active and can now in turn oxidize a dye molecule. In doing so, they themselves are returned to the reduced species so that they are available for renewed oxidation on the anode surface.
- the device according to the invention is characterized in that, due to its special design, it is able to scoop a particularly large amount of washing liquor when the washing machine is in use, which enables particularly efficient convection of the mediator species to the anode surface. In this way, sufficient activation and thus a bleaching effect can be ensured even with small amounts of mediator species.
- the high efficiency is achieved in the device according to the invention in that the at least one inlet and the at least one outlet are arranged on the device in such a way that, when the device is in use, they are directly above the inner circumferential surface of the washing machine drum and that the at least one inlet for introduction of washing liquor into the device lies in a plane, the surface normal of which extends essentially orthogonally to the axis of rotation of the washing machine drum when the device is in use, the at least one electrode being arranged within the device in such a way that its longitudinal extension is essentially parallel to the surface normal of the Extends plane in which the at least one inlet is located.
- the opening of the at least one inlet of the device or the surface normal of that surface in which the inlet opening is located always points in the direction of rotation when the washing machine drum rotates.
- the device mounted on the inner circumferential surface of the washing machine drum can scoop a comparatively large amount of washing liquor from the sump, especially when passing through the sump of washing liquor that collects in the lower area of the washing machine drum during operation of the washing machine, and this scooped washing liquor can then scoop up immediately is guided along the anode extending as an extension of the inlet.
- one embodiment of the invention provides that the at least one outlet also lies in a plane whose surface normal extends essentially orthogonally to the axis of rotation of the washing machine drum when the device is in use.
- a device designed in this way makes it possible to ensure sufficient convection of the activated mediator to the textile to be cleaned or of the deactivated mediator to the anode of the device, regardless of the direction of rotation of the washing machine drum.
- the housing encloses a first receiving space and a second receiving space, the at least one electrode being accommodated in the first receiving space and the voltage source being accommodated in the second receiving space, and the first receiving space being permeable for washing liquor and liquid-tight from the second receiving space is separated.
- the housing is preferably designed as a dimensionally stable housing made of a non-electrically conductive material.
- Advantageous materials are, for example, plastics with a low specific weight as well as high strength and impact resistance.
- the side of the housing facing the inner circumferential surface of the washing machine drum in the inserted position of the device can be convex in order to fit optimally into the curvature of the washing machine drum.
- the housing can be designed to be largely smooth and free of edges, in order to minimize damage to the item of laundry due to excessive mechanical stress during operation.
- the device comprises two or more electrodes, each electrode being connected to a pole of the voltage source. At least one electrode of the device is always connected to the positive pole of the voltage source and accordingly acts as an anode.
- further electrodes can be coated either as anodes or as cathodes.
- each electrode of the device can be coated as an anode or a cathode.
- the ratios (number of anodes) / (number of cathodes) and / or (anode surface) / (cathode surface) can in principle be freely selected and can be changed during the electrolysis process.
- Electrodes connected as cathodes are necessary in order to enable a sufficient counter-reaction to the electrochemical activation reaction at the anode.
- One or more electrodes of the device can be coated as cathodes. According to a proposal of the invention, however, it is also possible that all electrodes of the device are coated as anodes and the washing machine drum is coated as a cathode by means of appropriate electrical contact with the device according to the invention. In this way it is possible to maximize the anode surface required for the activation of the mediator, since the device according to the invention does not itself have to provide its own cathode surface. In addition, it has been shown that the skinning of the washing machine drum as a cathode has a positive effect on the corrosion resistance and the stability of the material of the washing machine drum.
- the device according to the invention preferably comprises a mechanism for making electrical contact with the washing machine drum.
- the electrodes connected as anodes can have various shapes and / or surface properties.

- Known surface treatment methods such as roughening, grinding, etching and / or pickling, can be used to enlarge the anode surface.
- an electrode of the device can be formed in a material identical to or different from the anode or anodes.
- the size and / or the volume and / or the surface and / or the mass of the cathode can also be identical to or different from the design of the anodes.
- the at least one electrode can, according to a further proposal of the invention, be designed as a tube through which washing liquor can flow.
- a tubular configuration of the electrodes offers reaction surfaces both on the inside and on the outside of the tube, so that the activation of the mediator species can take place very efficiently.
- the tubes can have a circular, elliptical or polygonal cross-section, with several tubes all tubes being able to have the same cross-sectional shape or also different cross-sectional shapes.
- the tubes can be made of a metallic material.
- the tubes are arranged such that, when the device is in use, the longest axis of the tubes is aligned essentially orthogonally to the axis of rotation of the washing machine drum. In this way it is possible to efficiently guide the amount of washing liquor scooped by the device when the washing machine drum rotates past the anode surface and thus to bring about sufficient activation of the mediator species.
- the diameter of the tubes can vary over their length.
- the diameter of the tubes can be widened in a funnel shape at their end facing the inlet and / or the outlet of the device. This effectively supports the efficient scooping of the washing liquor into the interior of the tubes.
- a tubular electrode for the purposes of the invention, it is also possible for a tubular electrode to comprise two half-tubes which are connected to the tubular electrode in an electrically non-conductive manner.
- one half-tube can be coated as an anode and the other half-tube that is electrically separated therefrom can be coated as a cathode.
- the ion resistance can presumably be minimized.
- a tubular electrode can be divided in the direction of its longitudinal axis into at least two tubular segments which are each separated from one another by a non-conductive material layer and which can be coated differently.
- washing liquor In conjunction with an acceleration sensor and a suitable control unit, it can thus be ensured that the washing liquor always first flows through an anode and only then through a cathode, regardless of the direction of rotation of the washing machine drum and thus of the flow direction of the washing liquor through the tubular electrodes. In this way it is possible to maximize the concentration of bleach-active, activated mediator species in the wash liquor.
- a further embodiment of the invention provides that the at least one electrode designed as a tube comprises an inner cavity or protuberance which is filled with washing liquor during the scooping process in which the device scoops washing liquor from the sump and only at a later point in time of the rotation when the device has clearly moved out of the sump again, it is emptied again.
- the mean residence time of the scooped washing liquor containing the mediator species on the electrode surface of the device can be extended. This increases the efficiency of the electrochemical process, since the specific yield of activated mediator per rotation is maximized.
- the device according to the invention comprises at least one sensor for detecting at least one variable selected from conductivity, temperature, state of motion, acceleration and sound.
- the device preferably also includes control electronics and / or a control unit to which the signals from the at least one sensor are fed and which controls and / or regulates the voltage source as a function of the signals from the sensors.

- the voltage source is designed in such a way that it can provide the current strength required for the selected potential.
- the voltage source is designed as a battery or as a rechargeable battery. In the case of a rechargeable battery, this can be removed from the device and, for example, can be charged in a separate, external device, but a direct connection of the device to an external charger can also be provided. In principle, charging can take place via a cable or an inductive process. Alternative known loading mechanisms are also possible.
- the device comprises a generator.
- a generator can use the “energy harvesting” principle to convert part of the kinetic energy from the movement of the device with the washing machine drum into electrical energy and thus directly operate the device or charge an energy store.
- the generator can absorb or pick up the energy by means of a pendulum, a flywheel or a turbine.
- the device according to the invention comprises its own voltage source, it is intrinsically functional and thus compatible with a large number of commercially available washing machines without having to make certain structural modifications or adaptations to these.
- the device can comprise control electronics by means of which the voltage can be controlled.
- This regulation can take place as a function of sensor signals; it can also take place as a function of parameters that are stored in a memory unit or are received via communication interfaces.
- the voltage can be controlled, e.g. depending on the degree of soiling of the laundry to be cleaned. It can also be regulated which electrodes are wired as anodes or cathodes at what point in time.
