Definitions
- the invention is based on a method for the mechanical cleaning of textiles or solid objects, such as dishes, using water-soluble detergents and / or cleaning agents and enzymes.
- Previously customary methods of the above type use enzymes as cleaning enhancers during the period of exposure to, for example, alkaline cleaning agents.
- enzymes are added to the washing process, for example in the form of a powder.
- different enzymes are required, which means that appropriate storage is required and the selection or dosing process is complex.
- carbohydrates or proteins dissolved or broken down during the washing process; Due to the presence of the alkaline cleaning agents, the enzymes themselves are attacked and either broken down or at least ineffective.
- undestroyed enzymes are rinsed out with the liquor after each washing process and therefore have to be added again and again.
- the object of the invention is to prevent the enzymes from dissolving or becoming ineffective and to avoid flushing out still usable enzymes.
- this object is achieved in that enzymes having a catalytic effect on typical soiling are added to the washing or cleaning process, and only for as long as their catalytic action is desired. Since the catalytic effect of the enzymes can only be used well in a low temperature range and, if possible, without the presence of alkaline cleaning agents, the enzymes used can be taken out of the washing process again after use and used again in a later washing process.
- the method according to the invention can be carried out with a detergent or cleaning agent in which the enzymes are macroscopically encapsulated by means of a polymer membrane which is permeable to water but insoluble in water. As a result, the catalytic action can take place through the membrane without the enzymes being distributed in the washing or cleaning liquor.
- the capsules consist of a plurality of hollow bodies connected to one another
- the enzyme-loaded membrane bodies are easiest to use from the circulation of the alkali - e.g. B. when pumping - to keep out.
- the hollow bodies can thus be connected to cartridges and / or plates and / or tubular bodies. This turns them into a larger unit that is easiest to stop mechanically in the lye flow.
- the capsules or the connected hollow bodies can be used in a machine for cleaning textiles or fixed objects (eg dishes) in a place that can be reached by the washing or cleaning liquor, but fixedly but interchangeably.
- the location is most appropriately protected by a filter against insoluble contaminants from the washing or cleaning liquor.
- capsules or hollow bodies are advantageously filled with enzymes set to different types of soiling .
- both the method according to the invention and a washing machine controllable by the method are shown schematically
- FIG. 1 shows a tent flow diagram of the water inlet processes, the increasing temperature profile and the sections for the addition of a cleaning agent or for the alkali contact with an inventive washing or cleaning agent based on enzyme and
- FIG. 2 shows a suds container of a washing machine with a coupled inlet for water and detergent and for the circulation of alkali through an enzyme container
- the ordinate O of the diagram in FIG. 1 contains a not specified scale for the amount of alkali L in the tub 1 of the washing machine in FIG. 2, for the temperature T of the alkali and for the amounts of detergents W or enzymes E on the abscissa A is not a close one the specified time scale Z is plotted
- the washing process shown in the diagram in FIG. 1 begins with the entry of water into the tub 1. As soon as a certain liquor level L has been reached in the tub 1, the liquor is in a quantity for a limited time ti, during which the tub temperature T is still low brought into contact by enzymatic washing or cleaning agent E, which attacks protein and carbohydrate-containing soiling in a washing item. Then, for example, an alkaline washing agent W is introduced into the alkali L, which remains dissolved in the alkali via an undefined time t2 and onto which loosening proteins and carbohydrates as well as other soiling of the washing item.
- the areas below the diagram limits for Enzyme E and Detergent W make the difference between the individual exposure intensities clear
- the inflow of water bypassing a detergent container 2 for the first phase of the water inflow in FIG. 1 is not shown in FIG. 2, however, after a certain amount of inflow water has reached the bottom of the tub 1 2 and the laundry has already wetted, the drain pump 3 is switched on in the example of FIG. 2 and the incoming water, insofar as it is not bound in the laundry, is fed through the drain line 4 at the bottom of the tub and the circulation line 5 to the enzyme container 6. There it takes up a limited amount of the stored enzymes 7 and transports them into the tub 1, from where the laundry item takes them together with the liquor, which in turn wets the laundry. In this way, by continuously exchanging water and alkali bound in the laundry, the entire laundry lot is gradually loaded with enzymes. This breaks down proteins and carbohydrates.
- the enzyme phase is ended by switching off the pump 3.
- the detergent 8 is rinsed out of the detergent container 2 during the opening of the valve 9 by supply from the water supply network 10 and fed to the tub 1 via the line 11. Then, if necessary, with further supply of water until a desired amount of alkali L is reached and while the alkali is heated up by means of a heater (not shown) to a desired temperature T, the detergent W can act on the split proteins and carbohydrates and on the other soiling on the laundry item and detach them from the laundry. Later they are pumped together with the used lye from the lye container 1 into a sewage network in a manner not shown,
- Enzymes 7 can be covered by innovations in process engineering (microsystems) with a thin, porous polymer membrane, which leaves the enzymes in a capsule, but enables an exchange of substances with the environment (required for the decomposition process of proteins and carbohydrates during washing), such macroscopic Capsules can be bundled in containers 12 (sieve-like cartridges or networking of the individual capsules with one another to form larger structures such as plates, tubular bodies, etc.) in appropriate amounts for the respective process and can thus be retained as part of the machine in the hydraulic circuit 3 to 6.
- suitable filters 13 may have to be connected upstream at the inlet and 14 at the outlet of the enzyme container 6 or the washing process should be designed accordingly.
- the method according to the invention and the associated detergent or cleaning agent thus include the possibility of the customer completely avoiding regular detergent additions.
- Neither environmentally harmful surfactant detergents of conventional type nor enzymatic detergents in powder form are required when using the method according to the invention and the detergents or cleaning agents.
- the detergent that is still required will, for example, in cartridge form as a treatment agent supply to the machine, if not for the duration of a washing machine or dishwasher life, at least for a longer period of time.
- Manual or automatic individual dosing of detergents or cleaning agents according to the invention with each washing process can be dispensed with, thus relieving both the customer and the environment.
- a separate structure or a separate cartridge for each type of enzyme or mixtures of different enzymes can be accommodated in a structure or a cartridge.
