Definitions

  • the invention relates to a method for operating a water-carrying electrical device and a water-carrying electrical device.
  • the invention relates to a method for operating a water-carrying electrical device with a bleaching device which is designed to carry out cleaning using an activated bleach, and a water-carrying electrical device which is designed to carry out the method.
  • the invention therefore presents the problem of providing a method for operating a water-carrying electrical device and a water-carrying electrical device in which fewer components have to be supplied to the water-carrying electrical device in order to produce an activated bleach.
  • the invention makes it possible to use a bleaching agent without storage containers or bottles expanding if stored incorrectly and loss of activity occurring if the bleaching agent is stored for a long time. It is possible to use a label-free bleaching agent for a cleaning process, since with the invention it is possible to produce the bleach-containing solution in the water-carrying electrical device and to produce and use it in situ in the cleaning process.
  • the bleach produced and/or the activated bleach preferably has a disinfecting effect in addition to the cleaning and bleaching effect.
  • the disinfection effect or hygiene effect between a bleach, an activated bleach and a disinfectant is considered to be equivalent.
  • an aqueous solution containing electrolytes is provided in the electrochemical cell.
  • the phrase “providing an aqueous electrolyte-containing solution in the electrochemical cell” is understood to mean that the aqueous electrolyte-containing solution is either arranged in the electrochemical cell or passed through it.
  • the electrochemical cell is designed to produce a hydrogen peroxide-containing bleach using the electrolyte, water, air and electric current. If the electrochemical cell has the electrolyte, water and air and an electric current flows, water is oxidized at an anode of the electrochemical cell, producing protons. At a cathode of the electrochemical cell, in particular a gas diffusion electrode, the oxygen contained in the air is simultaneously reduced. The protons are consumed and hydrogen peroxide is formed.
  • the cathode is preferably designed as an oxygen diffusion electrode.
  • the anode can be dimensionally stable Anode, a mixed oxide electrode or a boron-doped diamond electrode.
  • the reaction product of electrolysis is a hydrogen peroxide solution.
  • An anode space in which the anode is located and a cathode space in which the cathode is located are preferably spatially separated, for example by a membrane such as a cation exchange membrane, so that an alkaline hydrogen peroxide solution is preferably produced.
  • the bleach activator is supplied to the electrochemical cell and/or the bleaching device to react with the hydrogen peroxide.
  • the hydrogen peroxide further reacts partially or completely with the bleach activator to form an activated bleach such as peroxyacetic acid.
  • the bleach activator is selected from the group consisting of N-acetylcaprolactam, TAED (tetraacetylethylenediamine), triacetin, propylene glycol diacetate and triethyl citrate.
  • the bleach activators work well with hydrogen peroxide to form activated bleach.
  • the alkaline hydrogen peroxide solution in particular reacts very well with the bleach activator to form the activated bleach.
  • the TAED is preferably used as a suspension.
  • the electrolyte is preferably a builder or an inorganic salt.
  • a builder is a complexing agent and/or sequestering agent. Particularly in combination with one or more surfactants or other cleaning-active substances, the builder can further significantly improve the cleaning effect and dirt-holding power of the cleaning solution.
  • a builder also has the ability to help remove dirt from surfaces, making cleaning much faster.
  • the builder effect is independent of the effect as a complexing agent or sequestering agent.
  • a builder is also known as a scaffolding material.
  • the builder is also preferably designed to stabilize the hydrogen peroxide produced in the alkaline range, whereby the electrolytically produced hydrogen peroxide can be stored. By adding the builder, the electrical conductivity of the electrolyte solution is sufficient so that the electrochemical cell works in a current-effective manner.
  • the builder preferably has one or more components selected from the group consisting of or consists of citric acid, lactic acid, phosphonate, polycarboxylic acid, aminocarboxylic acid, polyacrylic acid and/or their salts.
  • the builder is one or more of the above components.
  • the inorganic salt is preferably sodium sulfate, sodium hydrogen carbonate, potassium hydrogen carbonate or potassium hydroxide. The inorganic salt serves to ensure current flow (conductivity) in the electrochemical cell.
  • the steps of providing the aqueous electrolyte-containing solution in the electrochemical cell and supplying the bleach activator into the electrochemical cell include passing the aqueous electrolyte-containing solution and the bleach activator individually or together through the anode compartment and the cathode compartment of the electrochemical cell.
  • the step of feeding the bleach activator into the bleaching device comprises metering the bleach activator upstream of the electrochemical cell, so that the bleach activator is passed through the electrochemical cell when it is fed into the bleaching device.
  • the step of feeding the bleach activator into the bleaching device preferably comprises metering the bleach activator between the anode of the electrochemical cell and the cathode of the electrochemical cell. This is advantageous if the anode compartment and the cathode compartment are separated from one another, and the bleach activator is preferably passed into the cathode compartment in which the hydrogen peroxide is generated.
  • the step of feeding the bleach activator into the bleaching device preferably comprises metering the bleach activator directly into the bleaching device; then the bleach activator is not passed through the electrochemical cell.
  • the electrochemical cell is preferably operated in parallel flow through the anode compartment and the cathode compartment.
  • the electrolyte-containing solution is supplied in parallel to the cathode compartment and the anode compartment, which are spatially separated.
  • a flow rate through the cathode compartment and a flow rate through the anode compartment may be the same or different.
  • the water-carrying electrical device can have a storage container which is connected in the circuit to the cathode compartment, and a further storage container which is connected in the circuit to the anode compartment which is separate from the cathode compartment. This allows the electrolyte-containing solution to be passed through the cathode compartment and/or the anode compartment several times.
  • the electrochemical cell is operated in flow successively first through the anode compartment and then through the cathode compartment.
  • the water-carrying electrical device can have a storage container which supplies the electrolyte-containing solution to the anode compartment or is connected in a circuit to the anode and cathode compartments.
  • the cathode compartment is connected to the bleaching device via a line.
  • the electrochemical cell is preferably flowed through once by the aqueous electrolyte-containing solution.
  • the device has one or more storage containers for the aqueous electrolyte-containing solution to flow through the electrochemical cell several times. This allows a yield of the electrolytically produced bleaching agent to be increased.
  • the method can have a step in which a liquid located in the bleaching device is supplied to the electrochemical cell. It is then possible to circulate this liquid through the bleaching device, the cathode compartment and the anode compartment. This allows an electrolyte-containing solution in the bleaching device to be passed through the electrochemical cell several times while it is activated. This allows electrolysis sales to be increased.
  • the invention further relates to a water-carrying electrical device with a bleaching device, an electrochemical cell and a regulating and/or control device which is set up and designed to regulate and/or control a method according to one of the previously described embodiments.
  • the water-carrying electrical device can be a privately used device or a commercially used device.
  • the water-carrying electrical device is preferably a device suitable for washing, rinsing and/or disinfection, which is used commercially or in the household.
  • the water-carrying electrical device is preferably a cleaning device.
  • the bleaching device is any device that is suitable for bleaching items to be cleaned or itself, such as the tub/drum unit of a washing machine, a washing compartment of a dishwasher or a disinfector.
  • the water-carrying electrical device is preferably designed as a washing machine, a dishwasher or a disinfector.
  • the electrolyte solution fed into the bleaching device is suitable, for example, as a cleaning agent for washing laundry items such as laundry, dishes, medical devices or laboratory devices and/or the bleaching device itself.
  • the washing machine, the disinfector and the dishwasher represent bleaching devices because they are particularly suitable for bleaching, cleaning and/or disinfecting items to be washed and/or washed.
  • coffee brewing and storage rooms of a coffee machine or rooms for preparing food and/or drinks in similar devices also represent a bleaching facility because they become contaminated with germs over time and are used to bleach, clean and/or disinfect themselves.
  • the bleaching device can therefore also be a device whose main aim is not to clean objects, but which becomes contaminated through use and itself has to be cleaned at intervals and is therefore temporarily used as a bleaching device in order to be cleaned itself.
  • the bleaching device therefore represents a device that is suitable for cleaning objects or cleaning itself by putting it into operation.
  • a coffee machine is a bleaching device which, in addition to its purpose of preparing coffee, is cleaned from time to time in order to prevent it from becoming calcified, dirty and/or contaminated with germs.
  • water-bearing "electrical device” also includes CIP (cleaning-in-place) systems or the like, which are used, for example, in hospital hygiene and the food industry.
  • CIP cleaning-in-place
  • the invention therefore also relates to a method for operating a device in which process engineering systems such as pharmaceutical systems or biological Systems are cleaned, which is usually carried out locally.
  • the system to be cleaned in this case represents the bleaching device.
  • the electrochemical cell is then connected to the cleaning device to be cleaned, preferably via a line.
  • the water-carrying electrical device preferably has the dosing device, which is suitable for supplying the electrolyte solution in a predetermined dose into the electrochemical cell, which is arranged between the bleaching device and the dosing device.
  • the dosing device is an automatic dosing device.
  • an automatic dosing device is understood to mean a dosing device which automatically supplies a predetermined dose of liquid to the electrochemical cell and/or the bleaching device when this is required.
  • the metering device can be designed in one or more parts. In a preferred embodiment, the metering device has at least two metering chambers which are designed adjacent or spaced apart from one another.
  • Each dosing chamber is preferably connected to the bleaching device via a line in order to be able to supply liquid to it during operation.
  • the electrochemical cell is arranged between the respective associated dosing chamber and the bleaching device, so that when a dosing activity is activated, the electrolyte solution is passed from the associated dosing chamber through the line into the electrochemical cell and then into the bleaching device.
  • the term dosing chamber also includes replaceable containers such as storage containers or bottles that are arranged in a holding device.
  • the lines can be hoses, pipes, channels or the like.
  • the electrolyte-containing solution may further contain one or more common ingredients for cleaning agents, preferably for washing laundry or rinsing dishes, medical instruments or laboratory equipment.
  • cleaning agents preferably for washing laundry or rinsing dishes, medical instruments or laboratory equipment.
  • these are surfactants, foam inhibitors, enzymes, enzyme stabilizers, color transfer inhibitors, graying inhibitors, optical brighteners, UV absorbers, thickeners, ion exchangers, water softeners, dyes and fragrances.
  • a cleaning agent can also be used which has the electrolyte-containing solution and one or more of the usual ingredients for cleaning agents mentioned above in the form of two separate liquids, whereby one liquid contains the electrolyte-containing solution and the other liquid contains one or more of the ingredients typical for washing or dishwashing detergents or cleaning agents, such as surfactants, enzymes, etc.
  • the two separate liquids are arranged separately in the metering device assigned externally or internally to the water-carrying electrical device, and the electrolyte-containing solution is supplied to the bleaching device via the electrochemical cell and, at the same time or with a time delay, the further liquid is supplied to the bleaching device directly, i.e. not via the electrochemical one cell supplied.
  • the additional liquid that are either not bleach-resistant and/or can themselves be electrolytically oxidized can be protected from degradation. This prevents ingredients that are sensitive to the electrolytically produced hydrogen peroxide and/or activated bleach from decomposing.
  • the water-carrying electrical device preferably has one or more storage containers. If the anode and cathode compartments are spatially separated, a storage container can each be assigned to the cathode compartment and/or the anode compartment, as described above.
