Definitions

  • the invention relates to a washing machine according to the preamble of claim 1.
  • the laundry drum is rotatably supported within the tub, the tub being supported in a suitable manner on the housing base by means of resilient and possibly also damping supports.
  • the storage of the laundry drum within the tub is, as is customary, carried out on one side by firmly and immovably attaching a type of support star to the rear of the tub by means of a large number of screws and tabs.
  • the arms of the support star extend to the peripheral areas of the tub and even encompass them in order to achieve particularly secure anchoring, because in the hub area of the support star the laundry which tends to jam during operation due to the amount of wet laundry filled in drum is held by only one double bearing on this side.
  • electromechanical transducers are arranged on parts of the supporting star which are exposed to particularly noticeable loads under the action of the drum weight .
  • the weight-proportional output signals supplied by these electromagnetic transducers for example strain gauges (DMS) or piezoelectric pressure transducers (PED) firmly clamped in the material of the supporting star then arrive at a signal processing device which is thereby enabled to evaluate, for example, the liquor level in the laundry weight by evaluating the laundry weight Detect and adjust the tub automatically.
  • the aim is only to enter an amount of laundry corresponding to the holding volume of the washing drum into the washing machine, that is to avoid errors which, due to the mere estimation of the laundry weight, either do not fully satisfy the drum washing machine's capacity exploiting the amount of laundry or that the washing drum is overloaded and the laundry is therefore not sufficiently thoroughly cleaned.
  • the upper cover plate of the washing machine is designed as a scale in this publication so that the operator can read off the correct amount of laundry;
  • the result of such a weighing process can also be used for the actual Liche program to change the washing machine, for which the weighing device can be coupled with the program control of the washing machine. No other intervention in the program flow or the respective fill quantities is intended.
  • the procedure is such that liquid-filled weight sensors working on a piezo-resistive basis are arranged in the lower fastening points of, for example, hydraulic shock absorbers supports of the washing drum or their containers.
  • the output signals of the weight sensors go to a central control circuit which, for example as a program-controlled microprocessor, should also be able to determine the amount of detergent to be added.
  • weight sensors regardless of their shape and design, are always in the area of the feet of the entire washing machine housing or the hydraulic suspension of the tub or the laundry drum are arranged so that their hydraulic properties must be included or included and, above all, the influence of the inlet hoses and in particular the sealing rubber sleeve in the door area of the drum is not taken into account, which is not mentioned at any point.
  • the sequence control relies on sensor data in order to properly control the operation of the washing machine from commissioning and the initial addition of the required amount of water to the last spin cycle can.
  • sensors are increasingly the weakest link in the processing chain, not only because because they come into direct contact with the media to be measured as actual value transmitters, but also because the increasing electronic equipment of washing machines means that work can be carried out with ever increasing accuracy, but which the previous actual value transmitters are not up to.
  • the central control circuit In the case of washing machines, it is furthermore desirable to provide the central control circuit with initial information about the amount of the laundry to be put into the washing machine; on the basis of this information, the latter can calculate the amount of water required in each case and control the inflow and determine and add the amounts of detergent automatically.
  • the object of the present invention is therefore to provide washing machines with a particularly precise, reproducible and, above all, aging stocks which can be used universally and which, including a determination of the amount of the items to be washed, contain all the necessary actual values of a central control circuit to ensure a precise program sequence and to the proper control of the fill levels.
  • the invention solves this problem with the characterizing features of claim 1 and has the advantage that not only proper operation of the washing machine and the best possible consideration of environmental conditions is ensured by the now highly accurate weight determination of all data of interest now achieved by the present invention, but at the same time also all other external sensors, level meters and the like previously required in washing machines. are unnecessary.
  • the program can not only determine the required fleet level for the various washing programs, but also the amount of water added, by weighing, after the precise measurement of the wash goods entered.
  • This enables the setting of any level in the continuous transition stands in the tub, combined with the addition of the required amounts of detergent of any shape and origin, i.e. liquid or free-flowing, since the amount of detergent added can also be determined by weight measurement.
  • a washing machine working in accordance with the specifications of the present invention is therefore able to clean laundry in a particularly economical but, on the other hand, also in a particularly effective manner, since the amount of laundry to be washed is processed precisely with the amounts of water and amounts of detergent that are found to be optimal for one have proven optimal cleaning process.
  • the invention therefore avoids all conceivable estimates here, which up to now have normally always led to the fact that operators, in order to be on the safe side, normally overdosed, under certain circumstances only out of ignorance about the actually required amounts of detergent or also because the particular amounts required in each case , for example according to the detergent manufacturers, have had to remain inaccurate by nature because the detergent manufacturer cannot, of course, precisely determine the weight of the respective laundry.
  • the present invention succeeds in completely eliminating all friction influences which have always led to weight data which cannot be reproduced or otherwise meaningfully evaluated, in particular due to the unpredictable formation of hysteresis.
  • weight sensor is not critical per se, although strain gauges are preferably used; However, other displacement / force transducers are also conceivable that emit a corresponding output signal that evaluates as weight, that is, piezoelectric systems, moving coil systems, string scales, proximity switches and the like.
  • a decoupling frame which, in relation to an outer housing and between it and the entire innards of the washing machine, stores the entire washing machine apparatus including the tub, washing drum, hydraulic supports, door system and other components, this decoupling frame even being located on the outside stationary housing is suspended by means of leaf springs and the strain gauge sensors that are preferably used here are attached to unc on these leaf springs.
  • the decoupling frame actually remains completely decoupled from all frictional influences, so that it is guaranteed that due to the highly developed weighing technology (leaf spring suspension with strain gauge measuring strips) measurements can actually be made in the gram-accurate range , even if only one or two teaspoons of a preparation for a rinse aid or the like. are needed.
  • strain gauge measuring systems used are able to provide absolute and relative measured values, with accuracies for example up to the fifth digit of a measured value. Even if one therefore bases on the fact that a starting weight of the decoupling frame with all washing machine innards at 100 kg or the like. lies, the output weight list signals achieved by the use of the present invention are actually determined to the exact gram, and in connection with such strain gauges known circuits and converters can be used to evaluate the supplied analog signals.
  • a particularly suitable analog / digital converter in this context is described in DE-PS 36 30 633, so that it is not necessary to go into more detail here on the measurement principle on which it is based.
  • a preferred embodiment of the present invention then consists in that the strain gauge sensors as Arranged part of a Wheatstone bridge and the bridge supply voltage is an AC voltage to avoid errors due to polarization voltages.
  • the invention therefore manages to achieve the best washing results with reduced water consumption and correspondingly precisely metered detergent consumption, while at the same time optimally protecting the environment, with only weight sensors having to be used and the addition of all the agents required for the respective washing process, including hot or cold water, automatically by means of corresponding valve actuation or from a induction bowl, if desired with different chambers.
  • the basic idea of the present invention is to use an additional decoupling frame to decouple the entire inner washing machine system from an outer stationary housing resting on a base by means of leaf spring suspensions, in particular to make it independent of frictional influences and to increase or decrease weight in the area of the washing machine drum and / or to determine the tub by fitting or assigning suitable weight measuring sensors, preferably strain gauges, to the leaf springs.
  • the washing machine 10 shown in a highly schematic manner in FIG. 1 comprises an outer housing 11, which is stationary, for example, via feet 15a, 15b on a stationary base 30.
  • a support 31 referred to below as a decoupling frame, of basically any shape ; in Fig. 1, this carrier 31 is Darge provides in a closed box shape, but the depth can be very small, so that such a decoupling frame 31 can be produced inexpensively by welding rails, including profiled rails, appropriately.
  • All other washing machine components are then suspended on this inner support or within the decoupling frame 31, that is to say the washing drum 12a within a tub 12, the latter in turn being in a suitable manner stored within the decoupling frame 31, for example via upper suspension springs 13a, 13b and lower support / damper elements 14a, 14b.
  • the storage of the laundry drum 12a within and through the tub 12 is of secondary importance; Such storage can be done, for example, by means of a suitable support star, via which the washing drum 12a is suspended on one side in the tub.
  • supporting carrier or receiving decoupling frame 31 is in turn suspended within the outer housing 11, preferably by means of leaf springs which are firmly clamped on both sides, and preferably only on one side.
  • the decoupling frame 31 supporting and supporting leaf springs 17a, 17b between the facing, in the 1 left side walls of the stationary outer housing 11 and the decoupling frame 31, the leaf springs being firmly connected at their two ends to the outer housing 11 or decoupling frame 31, for example welded.
  • FIG. 2 also shows a possible special shape of the leaf springs, with lower and upper notches at predetermined points, so that the leaf spring in each case in the area of these notches in the event of weight changes undergoes a change in shape that can be measured particularly well via strain gauges. Strain gauge sensors 18a, 18b can be seen above the notches 16. Alternatively, the illustration in FIG.
  • FIG. 2 shows yet another weight measuring arrangement 19, which can then be designed, for example, as described in more detail in the form of a differential coil 19 'in FIG. 3, with two coil partial windings 23a, 23b separated via a center tap 24, whereby a ferrite core 25 can be in a central or zero position at the start of the measurement, which is driven by the decoupling frames 31 that change their position when the weight changes.
  • FIG. 4 The structure of a washing machine implementing the basic principle according to the invention is shown in detail in FIG. 4; in this embodiment, the stationary outer housing 11 'to the front, that is to say in the drawing plane of FIG. 4 to the right and where the door of the washing machine is, have a completely open front, while the remaining outer wall parts including the bottom 11a', rear wall 11b ' , Upper cover plate 11c 'and side walls, not shown, are present.
  • the decoupling frame 31 which, without the need for side or top walls, consists only of the part shown in FIG 'Exists, which replaces the missing front of the stationary outer housing 11' and then the entire washing machine system including drum container is stored within this easily open frame.
  • the door seals the open fill opening 36 of the tub 12 'in a suitable manner, for example by a press-on rubber seal 37 and is optionally mounted directly on the tub 12'; but it can also, if desired or more advantageous, be mounted in the usual way on the visible front wall of the washing machine, that is, on the front wall 31b 'of the inner decoupling frame 31'.
  • the tub 12 ' is mounted within the decoupling frame 31 and fastened to it, possibly correspondingly resilient, so that the rubber seal 37 is stressed by relative movements when the washing machine is working, and there is no further distinction here usual washing machines results - on the other hand, it is ensured that this does not lead to frictional influences during the measurement, because as already explained above, it is the entire decoupling frame 31 ', which is resiliently suspended relative to the stationary outer housing 11', via which again here recognizable two leaf springs 17a 'and 17b'.
  • a lint filter is of course within the decoupling frame 31 '- a wide-ranging loop can be done, so that there are no measurement problems, for example, as shown for the supply hose in Fig. 4, what this The point of view is not necessary.
  • the container can also be of multi-chamber design, that is to say comprise a first chamber 38a and a second or third and fourth chamber 38b etc., the detergent also being able to be flushed in via the valve-controlled fresh water supply, if from another , not shown larger storage container in the induction and detergent container 38 each corresponding measured detergent amounts are entered in advance.
  • the procedure is preferably such that weight measurements are carried out by the dryer at predetermined times - all internal parts of the dryer are then separated from the stationary outer housing in the same way by a decoupling frame - and from the curve profile of the relative weight loss approximating a limit value asymptotically the degree of dryness achieved is closed, which is possible without any problem if appropriate stored curves are specified in the area of the central control circuit (microprocessor). It is then no longer a problem to determine, from known curve profiles, the points at which the laundry in the dryer has reached the drying levels "cupboard dry" or "ironing moisture".
  • a further advantageous embodiment of the present invention consists in the fact that the weight measurement also makes it possible to determine imbalance phenomena which exceed certain limit values in washing machine spinning processes and to initiate appropriate measures to combat imbalance.
  • the central control unit Microprocessor or small computer
  • the central control unit determined whether the dynamic weight fluctuations, which are supplied by the strain gage sensors during spinning processes, exceed certain limit values that can be easily determined by previous measurement; In this case, it is advisable to either stop the spinning process and / or to better distribute the laundry by means of short drum rotation cycles, including reversing, and then to restart the spinning process and / or to sound an alarm if the condition does not improve after repetitions.
  • a corresponding sequence for overall washing machine control can then take place as indicated as one possible exemplary embodiment using a flow chart (functional sequence) in FIG.
  • the usual status determination i.e. initialization of the values and reset at function block II, is first obtained.

  • a first weighing process (1st weighing) is initiated, with which the weight of the laundry is determined.
  • the microprocessor calculates the setpoint value from this quantity of laundry weight, the internal specification of what type of laundry is concerned, and a further internal specification, which may relate to a desired program, for example, and if necessary by calling up values stored in an EPROM the desired water level and opens the inflow control.
  • the microprocessor can determine the amount of detergent to be added so that a perfect washing process can be carried out. The desired amount of detergent can then be taken from an only occasionally replenished detergent supply.
  • the feed control for the electromagnetic solenoid valve for adding water is then opened and the water filling quantity is determined by a differential weighing process, with which the desired water level setpoint, as calculated, can be achieved.
  • the components used or the entire central control can be constructed in analog, digital or hybrid technology or, in part or in whole, corresponding areas of program-controlled digital systems, for example the microprocessor used, microcomputer and the like can include.
  • a preferred embodiment of the present invention still consists in the fact that the weighing system which is present anyway in such a washing machine can also tackle the problem of unbalance detection.
  • unbalance phenomena of the drum which were caused by an unevenly distributed content during its rapid rotation to the spinning process, had to be carried out either by mechanical switches or by an electrical measurement of the motor current, in which an unbalanced movement of the drum connected to the driving electric motor occurred, for example, by showed a pulsation of the current.
