Definitions
- the invention relates to a washing machine, also a washer-dryer or the like, with a washing drum in a lye housing, wherein the washing drum is rotatably mounted in the lye housing, in that the lye housing is guided or suspended relative to an outer housing of the washing machine, and that the washing machine has a first drive for rotation of the drum with respect to the lye housing. It is usually considered a resilient suspension of the lye housing relative to the housing of the washing machine.
- the object of the invention is therefore to provide a washing machine, also a washer-dryer or the like, which uses the so-called introduced mechanism to improve the washing performance. Likewise, a belonging to this process is to operate according to such a washing machine.
- this object is achieved in that an at least second drive is provided for a linear movement of the lye housing and the drum with respect to the housing of the washing machine.
- a second drive may be added to the movement, which receives the laundry by the, even reversing, rotation of the washing drum with their ribs and leads to a continuous falling of the laundry items in the washing liquor of the tub, a further movement can be obtained after the first found explanation should show as acceleration of the falling process of the laundry into the liquor.
- substantially vertical (in relation to the substantially horizontal floor surface mounted washing machine) movements are triggered by the least second drive, as well as transversely occurring movements can contribute to the accelerated washing result, since any movement between the laundry and lye for the cleaning result of the laundry is conducive.
- the thus occurring acceleration of the washing process can be reflected in a shortening of the washing time.
- the washing performance is increased according to the invention by up to 30 percent.
- a linear movement can take place by a conversion of a rotational movement of an electric drive, such as an electric motor with rotating output shaft in a linear movement, which could serve a geared eccentric or a pinion with associated rack, it has proved to be advantageous to a linear motor for the at least second drive.
- This can then either be a plunger anchor within a surrounding magnet coil, or a magnet coil arrangement can be selected with which a linearly moving field (see Transrapid) can be generated.
- Transrapid see Transrapid
- a drive which has, for example, only one eccentric and is physically connected to the tub, but has no geared connection to the housing of the washing machine, is also already suitable to realize the claimed teaching of the invention, as even then a linear movement of the tub body and the drum with respect to the washing machine housing can be formed. It has proved to be advantageous if it is effected by a control of the above-mentioned linear motor, that the drum is deflected in a nearly vertical direction by 3 to 40 mm, preferably 25 to 35 mm relative to the rest position in a positive and negative sense. Furthermore, it has been found that a frequency range for the movement of the drum according to the invention in the nearly vertical direction from 0.05 to 10 Hz, preferably from 0.1 to 5 Hz, is considered particularly favorable.
- the at least second drive is designed as an arrangement of a plurality of linear motors, that is, as a second drive system for linear deflection of the lye housing, wherein the plurality of linear motors are provided exclusively for driving connection between the lye housing and the housing of the washing machine , Then it is unnecessary to resiliently suspend the tub relative to the housing of the washing machine, since a guide of the tub in relation to the housing of the washing machine via the movable part or anchor of the linear motors can be done, the stationary part attached to the housing of the washing machine, in particular, preferred with more than one degree of freedom, is rotatably mounted.
- the linear motors incidentally in the deflection and frequency range as previously stated, then benefits can be gained because the properties of the springs otherwise required for suspension are not taken into account.
- the linear motors are controlled so that a damping of the resulting during the spinning oscillation of tub and drum is effected.
- the characteristic of the springs otherwise required for suspending the lye housing is not taken into account.
- active damping is effected by the control of the linear motors, so that basically the conventional dampers can be dispensed with. Again, there is also the possibility of energy recovery in the supply network.
- the invention is achieved in that, in the presence of a further drive system for the linear deflection of the lye housing and the drum relative to the housing of the washing machine, the method causes a washing process to be carried out more effectively or with higher performance.
- the acceleration of the washing process resulting from the further movement can, for example, be reflected in a shortening of the washing time.
- the washing performance is increased according to the invention.
- the drum is deflected in a direction transverse to its axis of rotation, in particular nearly vertical direction, by 3 to 40 mm, preferably 25 to 35 mm relative to its rest position in a positive and negative sense, wherein a frequency range of 0, 05 to 35 Hz, with a frequency of 35 Hz corresponds to a drum speed of 2100 1 / min.
- a frequency range of 0.05 Hz to 10 Hz in particular from 0, 1 to 5 Hz, and provided in a spinning process, a frequency of up to 35 Hz.
- the washing machine is equipped with a washing drum in a lye housing, the washing drum being rotatably mounted in the lye housing, and the lye housing is guided relative to an outer housing of the washing machine, and the washing machine is a first Drive system for rotation of the drum with respect to the lye housing
- the washing machine is a first Drive system for rotation of the drum with respect to the lye housing
- another drive system for linear deflection of the lye housing and the drum relative to the housing of the washing machine by the inventive method can also be effected, that in the step of spinning the introduced into the drum Laundry, a nearly complete damping of the resulting in this process step oscillations of tub and drum is effected without damper in the conventional sense are required.
- the energy generated during oscillation can be fed back into the supply network.
- Fig. 1 shows a schematic representation of a washing machine according to a first embodiment
- Fig. 2 shows a schematic representation of a washing machine according to a second embodiment.
- a washing machine 1 which can also be od as a washer-dryer. The like. Formed, shown with a housing 1 a of the washing machine. In the housing 1 a of
- Washing machine is initially a tub 3 of the housing 1 a with springs 9, in particular two springs 9 and 9 ', suspended.
- at least second drive 6 arranged as a linear motor, which establishes a connection between the lower portion of the tub 3 and the housing 1 a of the washing machine 1.
- the at least second drive or the linear motors 6 and 6 ' replace - at least as far as the leadership and connection of the lower portion of the sheet container with the housing 1a - the damper otherwise used for this purpose.
- the function of the linear motor or the two linear motors 6 and 6 ' will be explained in more detail below with respect to its or their particular significance for the invention.
- a washing drum 8 for receiving laundry W is rotatably mounted. About ribs 15 (only one is indicated), the laundry W is raised during the washing process continuously, so that they can fall into the liquor again and again.
- the drum is connected via a belt drive 4 to a first drive 5, such as an electric motor with a rotating output shaft.
- a first drive 5 such as an electric motor with a rotating output shaft.
- the belt drive can also be dispensed with if the electric motor is designed as a direct drive motor 5 '(FIG. 2), so that an axis of rotation 13 of the drum coincides with the axis or output shaft of the direct drive motor.
- a sleeve 7 connects a loading opening of the tub with an outlet.
- a balance weight 1 1 can be attached to the tub 3. All connected to the tub 3 in rigid or fixed relation components, such as the drum 8, the first drive 5, optionally with the associated belt drive 4 and the balance weight 11 can be considered as essential parts of the tub 3 attributable vibration system.
- a center of gravity 14 of the tub oscillating system results from the mass distribution in the batch container 3, which is usually achieved by the construction of the washing machine that the center of gravity 14 preferably on the axis of rotation 13 of the drum 8 and one of the connection points of the springs 9, 9 'and or the linear motors 6, 6 'formed plane lies.
- the washing machine 1 also has a program control 10 which is capable of supplying signals from a plurality of measuring points, as well as a measuring device 2, which is capable of detecting changes in position of the tub 3 with respect to the washing machine 1 or its housing.
- the program controller 10 is also connected via one or more signal lines 10 'with a drive control 20 in accordance with the program control 10 to the first drive 5 for rotation of the laundry drum and to the at least second drive, in particular to linear motors 6 and 6' to Achievement of a different position of the tub 3 with respect to the washing machine 1 or the housing 1 a, required power through lines 21 and 22 or 22 'can spend.
- the first drive 5 for rotating the laundry drum 8 receives the required power in the usual way by the interaction of program control 10 and the drive control, as denoted here by 20.
- the rotational speeds of the drum 8 for phases of the washing process and the phases of centrifugal processes are set or regulated. Since this is known in principle, this will not be explained further.
- the at least second drive, so linear motors 6 and 6 ' occupy the geometric local, as shown above, the location of the usual damper, to trigger in a washing process, an additional, linear movement of the laundry drum.
- linear motors can be easily constructed by a in a ring cylindrical stator with immersed soft iron anchor, it is preferably provided below that linear motors are formed by a multi-phase stator magnetic field, so that its armature in accordance with the linear migration of the stator magnetic field a fairly accurate, predetermined by the control position can take.
- the dynamics of the vibration on the measuring device 2 on the tub can be tuned in an excellent manner to the needs of the program selected by the program control 10 wash program. It goes without saying that the elastomeric sleeve 7 between the tub 3 and the housing 1 a of the washing machine 1 with respect to the dimensioning and the choice of material on this vibration situation is to interpret gene. Incidentally, it is found that the washing performance can be influenced or increased by the over the linear motors 6 and 6 'introduced or excited vibration of the oscillating liquor container system in a predetermined manner and indeed by up to 30%.
- a washing process can be carried out in a shorter time in the case of equally soiled items of laundry, or parts of the amount of detergent or introduced electrical energy can be saved for heating the wash liquor.
- the vibratory tub system is excited to oscillate by itself in a spin process by laundry W, which is generally unevenly distributed in the drum.
- laundry W which is generally unevenly distributed in the drum.
- There are numerous approaches to how this imbalance can be reduced by appropriate measures. It can, for example, the drum 8 detected when stopped (as by the measuring device 2) to high unbalance, and thus a more favorable distribution of the laundry W can be achieved.
- the linear motors 6, 6' and 16, 16 ' form an overall arrangement of linear motors belonging to the at least second drive according to the invention.
- a washing process can be achieved by driving the linear motors, a vibration of the tub substantially in the z-direction, with an amplitude of 3 to 40 mm, preferably from 25 to 35 mm of the oscillation, while a frequency of 0.05 Hz to 10 Hz, preferably from 0.1 to 5 Hz forms.
