Definitions

  • the invention relates to a program-controlled washing machine with a wetting process which can be adapted to the amount of laundry in a laundry drum, which is mounted in a tub such that it can rotate about a non-vertical axis, by means of a water supply system and a control device which can temporally control the supply of water into the tub, as well as a method for adapting the wetting process of a laundry batch to be treated in a laundry drum of a washing machine.
  • the wetting processes in particular should be optimised in such a manner that for each amount of laundry and the quantity of water in the tub which is adapted thereto, the respective laundry batch is wetted completely and uniformly in the shortest possible time, before the actual washing process begins.
  • Wetting phases known so far use an adapted reversing rhythm of the laundry drum at reduced drum speed or pre-filling of the tub when the laundry drum is at a standstill, followed by continuous turning of the laundry drum in the scoop direction and a following wetting phase as described hereinbefore, or with an inserted spinning phase to accelerate the penetration of the washing solution into the laundry as described hereinbefore.
  • the wetting processes used so far have not been satisfactory with regard to an optimised use of process sequences.
  • the known wetting processes have hardly taken adequate account of differently sized laundry batches so that no complete wetting takes place in the case of very large laundry batches (close to the load limit) whereas small laundry batches are treated for too long in the wetting phase, measured by their wetting success.
  • the uniformity of the wetting leaves something to be desired.
  • the object of the invention to set up wetting sequences in such a manner that the uniformity of the wetting can be satisfactory in each laundry batch and at the same time, the wetting processes can be automatically adapted to the quantity of laundry of a laundry batch in that the laundry is wetted with the optimum quantity of water or washing solution with uniform wetting so that the washing process can thus be begun.
  • a washing machine described initially is constructed by dividing the wetting process into as many wetting phases as the number of quantity stages provided for the laundry to be treated.
  • This division of the wetting process allows the respective steps of the process to be adapted to the amount of laundry present.
  • each phase of the wetting process comprises a section during which a predetermined level of water supplied during this section is set in the tub whilst the laundry drum turns continuously in a specific direction. It is thereby possible for the first time to reliably estimate the amount of laundry to be treated in each phase of the wetting process in order to adapt the subsequent profile of the wetting process thereto.
  • the direction of rotation of the laundry drum corresponds to the direction of effectiveness of a scoop device. Then, specifically during this section in which the level of the supplied water is determined continuously, the laundry is already intensively impregnated so that the quantity supplied can be determined sufficiently accurately.
  • a measuring device can be provided to determine that the predetermined level has been reached; for this purpose, a time-measuring device can be used as a measuring device to determine the opening time of an intake valve or a liquid-quantity measuring device can be used to determine the amount of liquid supplied.
  • the section advantageously lasts until the predetermined level is reached. According to a further embodiment of the invention, after a comparison with a reference value it can be decided whether, as a result of the size of the laundry batch, the section should be followed by a second and/or further phase of the wetting process to which a stage with reversing drum movement is allocated. This stage can be incorporated, for example in the section with continuous turning of the drum or ahead of this section.
  • the measuring device for achieving the predetermined level and/or the comparator is switched off during the reversing drum movement, an appropriate wetting of the laundry batch can be carried out without supplying further water which would cause the dampening in the present laundry batch, which is perhaps too small for so much water in a manner unrecognised hitherto, to reach oversaturation.
  • the size of the laundry batch can only be determined in the following section of the wetting by unidirectional turning of the laundry drum in the scoop direction again using the amount of water supplied which is now to be measured.
  • a rotational speed of about 20 rpm has proved to be very suitable in a given geometry of the tub/drum system.
  • the reversing drum movement in coordination with the design features of the tub and/or the laundry drum at a rotational speed in the range of 40 rpm has proved to be very suitable. From these conditions, the phases of the wetting process can last between 10 and 40 seconds which overall results in a temporally ideally optimised wetting process.
  • FIG. 1 is a wetting process for a large laundry batch using a diagram
  • FIG. 2 is a schematic diagram of the relevant parts of a washing machine for the invention, in which a wetting process is applied according to FIG. 1 .
  • FIG. 2 A prerequisite for the description of the wetting process shown in FIG. 1 is a washing machine according to FIG. 2 comprising a tub 1 in which a laundry drum 2 is mounted and which is driven by a drive motor.
  • the axis of rotation 3 of the laundry drum 2 is upwardly directed from the horizontal towards the front by a small angle (e.g. 13°) so that the user of the washing machine obtains easier access and view into the interior of the laundry drum 2 .
  • the washing machine also has a liquid supply system comprising a water connection fitting for the domestic water network 8 , an electrically controllable valve 9 and an inlet 10 to the tub 1 which can optionally be guided via a detergent flushing device 11 from which the water supply can convey portions of detergent into the tub.
  • the valve 9 can be controlled by a control device 12 depending on a program sequence plan which can be bound to a time program and/or to reaching specific measured values of parameters (washing liquid level, temperature of washing liquid, rotational speed of the laundry drum etc.) inside the washing machine.
  • a liquid heating device 13 which can likewise be switched by the control device 12 and according to similar criteria.
  • a washing program typically begins, as in FIG. 1 , with the opening of the valve to pass water from the domestic water network 8 into the tub 1 . There, the water should be brought into contact as quickly as possible with the laundry 7 stored in the laundry drum 2 so that on the one hand the entrained detergent and on the other hand, the heat introduced by the heating device 13 can be transferred to the laundry 7 as rapidly as possible.
  • the rotational speed n of the laundry drum 2 is plotted as a function of time t because the rotational speed control in particular characterises the new type of wetting process.
  • the water supply, optionally supply of detergent and control of the heating device 13 are carried out in accordance with the prior art.
  • the overall wetting process stored in the program comprises three phases Ph 1 to Ph 3 which are faded in or out as required.
  • the wetting process is followed directly by the washing process W which continues with a known form of reversing drum movement.
  • the drum 2 is set in motion. In this case, it is moved exclusively in one direction and specifically in the direction (arrow 14 ) in which the scoop devices 5 on the laundry drum 2 act as prescribed.
  • the desired rotational speed of the laundry drum 2 is set at a value of about 20 rpm for the selected geometrical dimensions of the laundry drum which, however, are not described in further detail here.
  • the actual rotational speed however fluctuates about this value according to the respective distribution of the laundry batch in the laundry drum.
  • the drum movement is maintained for a duration of about 15 seconds. Specifically, the movement lasts until the required initial quantity of supplied water is present in the tub 1 .
  • the value of this initial quantity is determined and specifically either by measuring the valve opening time which is a measure for the absolute quantity supplied assuming that the specific quantity supplied by the valve 9 is sufficiently uniform, or by direct measurement of the quantity supplied, for example, using a flow meter (not shown).
  • the value for the initial quantity is set in relation to the attainment of the desired liquid level N 1-o in the tub (at 121 ) which is monitored by a level measuring device 15 so that the amount which has been absorbed by the laundry batch 7 is obtained directly from this.
  • a large batch of laundry absorbs a large amount of water so that the initial quantity of water supplied before reaching the desired level N 1-o in the tub 1 increases more rapidly than for smaller laundry batches.
  • the invention makes use of the differences described between different-sided laundry batches in order to decide, using these differences, whether the wetting process can be interrupted here (in the case of a small laundry batch) or whether it must be continued in a particular manner.
  • the initial quantity of water supplied is almost completely (apart from the remainder of the free liquid) absorbed because all the parts of the laundry batch come into contact with the supplied water without appreciable delay. If the laundry batch has been identified as small in this way, then at this point a transition takes place immediately to the washing phase W.
  • a second phase Ph 2 of the wetting process is initiated.
  • This second phase begins with a first section A R2 and a reversing drum movement with, for example, four short intervals of rotational speeds of up to 40 rpm in each direction. Single short-spin intervals can also be embedded in this section to flood the laundry better with the newly absorbed liquid.
  • the level regulation is switched off in this section A R2 , i.e. the water supply is not switched on when the actual liquid level falls below the desired level. Thorough mixing of the laundry batch is hereby achieved and the laundry is also given the opportunity to become further wetted by the water which has already been supplied.
  • This section A R2 can be several minutes long and can contain more intervals than is represented here by merely a few intervals within a relatively short time duration. The duration of this section A R2 is substantially dependent on the selected reversing rhythm, the liquid level and the technically complex circumstances.
  • the total quantity of water supplied before reaching the switching point N 2-o , as in the phase Ph 1 is a measure for the amount of water and determines whether (in the case of a medium amount of laundry) a transition is now made directly to the washing process or whether a further phase Ph 3 of the wetting process is initiated.
  • the typical value of the total amount of water for specifying “medium amount of laundry” is a maximum of 18 litres.
  • phase Ph 3 is initiated which again begins with a first section A R3 and reversing drum movements with short intervals of rotational speeds up to 40 rpm in each direction and possibly even with inserted short-spin intervals.
  • the level regulation is again switched off here so that no further water is introduced during the wetting movement.
  • the structure of the movement sequence and its dependences correspond to the same section A R2 in the phase Ph 2 .
  • This phase Ph 3 is also followed by a section A D3 in which the drum 2 is continuously driven unidirectionally at about 20 rpm and which is again used for filling with water.
  • the desired liquid level N 3-o however is now the level provided for washing and is no longer used to determine the amount of laundry.
  • the washing process begins with known parameters.
  • the duration of the thorough mixing in this continuous rotation section can be varied from one phase to another; this duration preferably becomes longer with increasing number of phases.
  • the levels of the individual phases should also increase, but at least from the first phase Ph 1 to the second phase Ph 2 .
  • Liquid levels increasing with the number of the phase increase the relative total amount of water for large laundry batches; however, more intensive dampening of the laundry is achieved more rapidly. If a constant level is selected in higher phases, a high scoop performance of the laundry entraining devices 4 and good regrouping of the laundry within the laundry batch should be ensured for satisfactory dampening.
  • the laundry batches can also be differentiated more strongly as is convenient. However, this involves an increase in the number of phase which then can be shortened in each case, particularly in the reversing section A Rx . Nevertheless, the entire program duration of a wash cycle can be shortened as a result of the more uniform dampening.
  • a level- or load-dependent matching of the drum speed in the scoop direction 14 can be appropriate to optimise the scoop action if the dampening is to be intensified and/or accelerated. Instead of the connection ahead thereof which is proposed, it can be advantageous for programming reasons to incorporate the reversing phases in the continuous rotation phases.
  • the reproducibility of the dampening and the washing action can advantageously be improved with the measures according to the invention because the water is let in at defined times and under defined conditions.
  • the adaptation of the water level to the amounts of laundry introduced can result in refinement of the load-dependent process conditions, especially in the case of small laundry batches.
  • the uniform dampening is improved in the case of large laundry batches. This is aimed overall at optimising the required amounts of water so that as a result of the differentiation considered over longer time intervals, a saving on the water consumption can be observed.
