Definitions
- the invention relates to a method for washing a laundry item from textiles susceptible to shrinkage in a program-controlled washing machine, which during the treatment is moved in a process section adapted to the needs of the textiles in a rotatably mounted laundry drum with the passage of water and, optionally, detergent, in which the On and off duration of an engine is specified, which rotates the laundry drum, and a washing machine for performing this method.
- a method for washing wool which is a shrinkage endangered textile.
- the laundry drum is driven during successive phases of movement and rest with a motor which accelerates the laundry drum over a ramp to a speed of 45 1 / min during the very short movement phases, whereby in successive phases of movement, the direction of rotation of the laundry drum changes.
- the duration of each resting phase is a multiple of the duration of the movement phases.
- a disadvantage of such a method is that the textiles are not completely wetted with water or alkali even after several phases of motion and are not sufficiently flooded for the purpose of cleaning.
- the invention is therefore an object of the invention to provide a method and a washing machine for performing the method that during a tailored to the needs of shrunken textiles washing process, the textiles are wetted and flooded early with the optimum amount of water or alkali and thus the Washing process for shrinkable textiles is optimized.
- the method described in the introduction is formed by the ratio of the switch-on duration to the possible switch-on duration of the motor during of the process section is smaller in sections or continuously.
- the shrinkage sensitivity of the textiles only rises sharply with the duration of treatment. Therefore, it is particularly advantageous to move the textile relatively strong at the beginning of the washing process, whereby a quick wetting and good flow of the textile can be achieved with water or alkali, without causing excessive shrinkage of the textile.
- the shrinkage sensitivity increases due to the increasing duration of the action and, if appropriate, due to an increasing treatment temperature of the water or the alkali. Therefore, in the inventive method, the degree of movement of the textile is advantageously reduced with increasing treatment time in accordance with the increase in shrinkage sensitivity.
- Such a reduction of the movement of the textiles is achieved by reducing the ratio of the duty cycle to the possible duty cycle of the engine. This means that the duration of the respective switch-on times of the engine is reduced and / or the duration of the respective switch-off times are extended during the washing process progress.
- the rapid wetting of the textiles is advantageously assisted by raining the scooped water over the laundry during rotation of the laundry drum, on the inside of her coat a means for scooping the water from the bottom of a tub is arranged, if the scoop is located in one position higher than the laundry items.
- the textiles are not only wetted by the free liquor, but they are treated on all sides with water or alkali.
- the laundry drum is rotated during the process section exclusively in one direction or with alternating directions of rotation, thereby advantageously a rearrangement of the textiles within the Wäschepostens is achieved so that all laundry is wetted evenly.
- rotating the laundry drum with changing directions of rotation at a speed of, for example, 25 to 35 l / min is more favorable for a rapid rearrangement of the laundry items within the laundry item, since at such speeds the laundry items are further lifted by the carriers and the drum jacket fall back to the bottom of the laundry drum, whereby a random distribution of laundry achieved and the laundry items is thus redistributed very quickly.
- the rotation of the weighing drum takes place in the direction in the effectiveness of the scooping device.
- the scooping device is optimally filled with water or liquor when the laundry drum is rotated, and when the scooping device is above the laundry item, the quantity of water taken in from the scooping device rains on the textiles.
- the inventive method is advantageously developed in an operation of the laundry drum, which has a scooping device with an optimal effectiveness for one direction of rotation, that the laundry drum is rotated in the direction of effectiveness of the scoop with a duty ratio of this direction, which is greater than the duty cycle of the opposite direction is.
- a development can also be clearly supported in the operation of the laundry drum with changing directions of rapid wetting of the laundry costs through the optimal use of the scooping device.
- the rapid wetting and flooding of the textiles is further promoted particularly advantageous in that at the beginning of the washing process, the duty cycle is greater than 12%.
- the duty cycle is greater than 12%.
- a duty cycle of less than 5% is selected in a further embodiment of the method at the end of the washing process. It has been found that just at the end of the washing process, the shrinkage sensitivity has increased so much due to the previous and ongoing softening of the textile, that with such a small movement of the textiles an excessive shrinkage of the same is effectively avoided. Since the textiles are treated with a high proportion of movement at the beginning of the washing process, despite the slight movement at the end of the washing process, the absolute washing mechanics entry or the required mechanical energy required for the cleaning is ensured and optimum cleaning is achieved with little shrinkage of the textiles.
- drum rotation in coordination with the design features of the tub and / or the laundry drum at a speed of 15 to 35 1 / min for all possible embodiments of the method according to the invention is particularly advantageous.
- the exact speed value can be optimized depending on the geometry, function of the driver and the preferred direction of rotation.
- the drum movement in accordance with the design features of the tub and / or the laundry drum with a break of 10 to 60 seconds has proven to be particularly suitable.
- the wash liquor has the opportunity to act sufficiently intense on the textiles.
- FIG. 1 is a schematic sectional view through a tub with a laundry drum
- FIG. 2 a qualitative functional profile of the shrinkage sensitivity as a function of the duration of action of a textile during the washing process
- FIG. 3 shows a qualitative functional profile of the duty cycle as a function of the washing process duration
- Fig. 4 shows a unidirectional movement sequence of the laundry drum according to the invention based on a diagram
- FIG. 5 shows a movement section according to the invention of the laundry drum with changing directions of rotation on the basis of a diagram.
- a washing machine has a laundry drum 1 rotatably mounted in a storage container 2 shown in Fig. 1 and a motor, not shown, which drives the laundry drum 1.
- a motor not shown
- the degree of movement or the washing mechanism of the laundry depends on the geometric dimensions of the laundry drum 1 and the driver 3 and the speed of the laundry drum 1.
- the drum diameter of the washing machine of the preferred embodiment is 50 cm. There are also other drum diameter possible, in which case in particular the drum speed must be adjusted accordingly for each drum diameter.
- FIG. 2 qualitatively shows a course of the shrinkage sensitivity SE of a textile, for example wool, as a function of the exposure time t during a washing process.
- the exposure time t or the duration t of a washing process is plotted on the x-axis of the diagram and the shrinkage sensitivity SE is plotted on the y-axis.
- the shrinkage sensitivity SE indicates the capacity of a garment to what degree the length dimensions of the garment change during its treatment.
- the shrinkage sensitivity SE is given as a ratio of the instantaneous linear expansion to the longitudinal extent of the item of laundry prior to the treatment thereof in percent.
- the shrinkage of the textiles is determined by the entry on mechanical energy, for example in the form of textile movement. Therefore, the parameters of the speed of the laundry drum 1 and the duty cycle of the engine, which significantly influence the textile movement, to match the shrinkage sensitivity SE of the textiles. In addition to the textile movement, the shrinkage of the textile is also influenced by the temperature of the treatment medium.
- the shrinkage sensitivity SE at the beginning of the washing process is still relatively low, since the individual fibers are not yet swollen by the low exposure time.
- the otherwise very sensitive to shrinkage textile can be moved more, without causing excessive shrinkage of the textile by this movement.
- the washing machine therefore has a program control device with means for controlling the motor and for controlling the course of the drum speed according to FIGS. 4 or 5.
- the motor is turned on during the phase A successively for the duration T_e of 12 sec and turned off for T_a of 48 sec, the motor is controlled such that during the switch-on the Wash drum 1 rotates at a speed of 22 1 / min.
- the laundry drum is maintained at a constant duty cycle during the washing process. nis ED of 12% moves. The resulting total acting on the textile mechanical energy is about as large as in the embodiment of the invention.
- the change in the duty ratio ED during the washing process in the preferred embodiment according to FIG. 4 is shown in the diagram according to FIG. 3 (continuous function line).
- the ratio of the duty cycle ED during the duration t of the washing process can be continuously reduced according to the dashed line in Fig. 3.
- the laundry drum 1 has a Wäschemitneh- 3 shown in Figure 1, which are equipped with scooping devices 4 and 5 have on their ridge sections holes 5, is rained by the water from the lower portion of the tub 2 drawn water over the laundry items 6, when the driver 3, as the driver 3.1 in the presentation, by turning the laundry drum 1 in the direction of the arrow 7 in a lying above the laundry item 6 position.
- the laundry drum 1 rotates exclusively in the direction of arrow 7, thus the effectiveness of the scooping device is used optimally and the laundry items 6 on all sides acted upon with water or brine. As a result, the rapid wetting and flooding of the textiles of the laundry items 6 is advantageously supported.
- the laundry drum 1 rotates with changing directions of rotation at a speed of +33 and -33 1 / min.
- the switch-on time T_e1 of the motor is longer than the switch-on time T_e2 of 9 seconds for the rotation of the laundry drum 1 in the direction of the arrow 7 shown in FIG. 1 or in the direction of the effectiveness of the scooping device 4 the rotation of the laundry drum 1 in the opposite direction.
- the switch-off durations T_a1 are 45 sec and T_a2 51 sec.
- the duty ratio ED_1 of the motor for the rotation of the laundry drum 1 in the direction of the efficiency of the scooping device 4 is 25% greater than the duty cycle ED_2 of the counterclockwise direction of 15%.
- the switch-on and switch-off durations T_e1, T_a1, T_e2 and T_a2 are selected in the second exemplary embodiment such that the average switch-on duration ratio based on the entire phase A is 20%, as in the first exemplary embodiment.
- the turn-on and turn-off times T_e and T_a of the engine and the rotational speeds of the laundry drum 1 are not limited to the numerical values given for the two exemplary embodiments in the inventive method, but they can take into account the needs of the textiles to be treated and the geometric dimensions of the laundry drum. 1 and the driver 3 are varied within the claimed ranges.
