Definitions
- the invention relates to a method for wet treatment of laundry items according to the preamble of claim 1.
- the laundry lies over part of each revolution of the drum both in front of the blades as well as on the inside of the drum. If during the rotating drive the Drum the blades off-center therein an upper turning point Reach or pass through, the laundry falls due to gravity in the Inside the drum. The laundry is thrown off the Paddles and the inside of the shell of the drum.
- the object of the invention is a method to create more effective and efficient wet treatment of laundry.
- a method for solving this problem has the measures of claim 1. Because the drum is driven at different rotational frequencies, the rotational speed of the same can be changed so that it meets the requirements justice. The disadvantages of driving a drum higher rotational frequency can be eliminated by the rotational frequency is temporarily reduced. This allows the faster one to take place in the rest of the time Drive the drum fully unfold its advantages.
- the drum is preferably driven in a revolving manner, during at least some, but preferably all, revolutions of the drum are driven by the same different rotational frequencies during the respective revolution.
- the drum is thereby with a different during at least some rounds Speed profile driven, with lower drive speeds then should be selected if excessively high drive speeds would lead to disadvantages.
- the drum is driven faster, with a higher overall treatment performance in the continuous washing machine is achievable.
- the drum is moved during each Orbit driven with at least two different rotational frequencies, each are substantially constant over part of one revolution of the drum. Therefore the drum runs in areas at the same speed, which leads to a Uniformization of the wet treatment of the laundry leads.
- phases of driving the drum with less or higher rotational frequency to brake or accelerate the drum. It comes to a stepped speed profile, the phases of the Acceleration or deceleration of the drum serve the higher or to achieve lower rotational frequencies and / or rotational speeds of the drum.
- braking the drum from the higher rotational speed the lower circulation speed leads to impulse loading of the laundry, which makes it easier to separate it from the drum and blades, in particular, an effective and, above all, complete dropping of the laundry is guaranteed is.
- the drum is larger Part of the circumference driven with a higher rotational frequency than with a smaller one Rotation frequency. This will reduce the speed of the drum drive reduced to a minimum, thereby increasing the performance advantage through a larger one The maximum possible circumferential speed of the drum is maintained.
- the drive when the blades the drive reaches the upper reversing area of the drum - or shortly before the drum braked so far that it moves from the higher rotational frequency to the lower Rotational frequency reached.
- the laundry gets a dynamic Impulse that detaches them from the blades and the inside of the wall the drum favors, so that a reliable discharge of all laundry on upper vertex of the drum is guaranteed. So it's not just that Effectiveness of the shedding of the laundry in the crown area of the blades by the Improved drum speed reduction. Rather, it will Reliable dropping of the laundry due to the required braking of the drum favored or amplified to reduce the rotational frequency of the same.
- the continuous washing machine 10 shown is preferably used for the wet treatment of Laundry in commercial laundries. Be in the continuous washing machine 10 Washed items 11 schematically shown in FIGS. 2 and 3, rinsed and optionally a post-treatment, for example equipment, subjected.
- the continuous washing machine 10 has an elongated drum 12 with a cylindrical drum shell.
- the drum 12 is horizontal Longitudinal central axis 13 can be driven in rotation. In the continuous washing machine shown here 10, the drum 12 is driven entirely or predominantly in a rotating manner. The Drum 12 thereby executes successive full circle rotations.
- the drum 12 of the continuous washing machine 10 shown here is divided into different zones, namely a washing zone, which may consist of a Prewash zone and a rinse zone can be composed of a rinse zone and optionally an equipment zone.
- the washing zone, the rinsing zone and if necessary the finishing zones are in the treatment direction 14 in succession in the drum 12 of the continuous washing machine 10 is arranged.
- the washing zone, the rinsing zone and possibly also the equipment zone are formed from several in the longitudinal direction of the Drum 12 successive combs 15, the number of combs arbitrary can be, so is not limited to the embodiment shown in FIG. 1.
- the chambers 15 can have different internals.
- an input hopper 17 is arranged in front of one (left in FIG. 1) input end 16 of the drum 12 Continuous washing machine 10. Via the input funnel 17 can be washed items 11 through the input end 16 in reach the drum 12 of the continuous washing machine 10.
- output end 18 of the drum 12 of the continuous washing machine 10 is in Embodiment shown an output chute 19 arranged. washed Items of laundry 11 that leave the drum via the discharge end 18 are over the discharge chute 19 is transported out of the continuous washing machine 10, and to a subsequent drainage device, not shown, if necessary, such as a dewatering press.
- the individual chambers 15 of the drum 12 are vertical, perpendicular to Partitions 20 extending longitudinal central axis 13 of the drum 12 are separated from one another. In the areas of the partitions 20, the individual chambers 15 are above Entire longitudinal central axis 13 continuous drum 12 running in one piece connected.
- the partitions 20 between the chambers 15 have openings. Between each two adjacent partitions 20 are preferably each Chamber 15 internals provided, and preferably blades 21. In particular a blade 21 is provided in each chamber 15, the blades 21 of all Chambers 15 can be of the same or different design.
- the drum 12 is movable by means of supports 22 symbolically shown in FIG. 1, namely rotating on a frame, not shown, of the continuous washing machine 10 supported.
- the supports 22 are designed as impellers on which the jacket of the Drum rests, with the casing rotating the drum 12 around the Rolls the longitudinal center axis 13 on the rollers.
- the drum 12 is driven in a special way. This drive takes place with different rotational frequencies.
- the Drum driven with two different rotational frequencies.
- Each of the two Rotational frequencies are constant over part of the rotation of the drum 12.
- the Speed profile in one revolution of the drum 12 is in FIG Circumference of the drum 12 shown schematically around. Accordingly, the drum over a large part 23 of their circumference or a circulation with a larger one Rotation frequency driven by up to fourteen revolutions per minute.
- This Rotation frequency is constant over the largest part 23 of the rotation of the drum 12. about a smaller part 24 of its circumference becomes the drum 12 with a constant smaller rotational frequency driven.
- the lower rotational frequency is at a maximum 5 revolutions per minute, which is a third less than the high rotational frequency.
- the drum 12 becomes larger Rotation frequency (part 23) braked continuously to the lower rotation frequency (part 24).
- the lower rotational frequency Acceleration phase 27 This also extends over a small part of the Circumference of the drum 12 and serves to accelerate the drum from the small Rotational frequency (part 24) to the higher rotational frequency (part 23).
- That part 24 of the circumference of the drum 12 over which it has less Rotational frequency is driven, is located in the upper reversal area of the blade 21 in the respective chamber 15 of the drum 12, that is, where the laundry items 11 the reach the upper vertex of the drum 12 and here from the blade 21 are dropped by falling down in chamber 15 (Fig. 3).
- Part 24 the circumference of the drum 12 with which it has the lower rotational frequency is driven begins approximately where the center of the blade 21 in the highest point reached the drum 12, i.e. intersects a vertical longitudinal central axis of the drum 12.
- the part 24 on which the drum 12 is driven at a lower rotational frequency ends where one end of the blade 21 on the inside of the shell of the drum 12 meets.
- the parts 23 and 24 can be used to drive the drum 12 be larger or smaller with a constant higher or lower peripheral speed than the areas in the exemplary embodiment in FIG. 3 26 and the acceleration phase 27 may be larger or smaller than that shown Embodiment.
- the braking phase 26 and the acceleration phase 27 can may also be of the same size or the acceleration phase 27 be greater than the deceleration phase 26.
- the exact lengths of these phases depend in addition to the formation of the blades 21 and other internals in the drum 12 also on the ratio of the different speeds. So you can can be varied according to needs, so that the invention is based on the Fig. 3 shown peripheral speed profile of the drum 12 is not limited.
