Description
Technical field
The present invention relates to a kind of home appliances for care of laundry items object, it has at least one for receiving clothing thing
The laundry drum of part, and with least one imbalance compensation device, the imbalance compensation device has housing, and multiple is mended
Repay element and be included in the housing with moving.Additionally, the present invention relates to a kind of method for running home appliances.
Background technology
During the washing process of washing machine, it is known that can occur the random and uneven of clothing object in laundry drum
Distribution.This causes imbalance, and the imbalance causes the larger mechanical oscillation of laundry drum and thereby also causes whole home appliances
Big mechanical load.On the one hand the vibration caused by produces the noise felt bad for user；On the other hand, this also can
Cause the mechanical load of floor layer, household electrical appliance are positioned on the floor layer.
In order to the vibration of laundry drum is prevented or at least greatly reduced in the operation of washing machine, in the prior art
It is through suggestion, annular imbalance compensation device is --- also known with title " ball balancer " (Ball-Balancer) --- tight
Gu on laundry drum.This imbalance compensation device has the hollow shell of annular, there is compensation quality in the housing, compensates
Quality is for example provided in the form of multiple spherical compensating element,s.The compensation quality can be moved in enclosure interior it is supported, and
And (rotating speed of laundry drum is higher than " resonance rotating speed ") tends to move to and uneven matter when the overcritical operation of washing machine
Amount --- diameter on laundry drum --- on opposite side, thus to set up the corresponding weight for unbalance mass,
And therefore equilibrium establishment on the whole.The movement for compensating quality is automatically carried out, and by being acted to balance mass
Power causes, vibration, the rotation of laundry drum and the gravity that the power is caused due to imbalance during the operation of washing machine and shape
Into.The shortcoming of such imbalance compensation device is that especially when the subcritical operation of washing machine, (rotating speed of laundry drum is less than
" resonance rotating speed "), compensation quality is moved towards unbalance mass, direction, thus more exacerbates vibration.
For example publication US 2011/0203325A1 then illustrates this configuration.
A kind of washing machine as known to the 872A1 of EP 2 441, in the case of the washing machine, ball can be arranged in two
The electromagnet that laundry drum outside and position are fixedly placed in washing machine shell is influenceed by the magnetic field produced by it.
Two electromagnets are all disposed within a upper area.Magnetic field as produced by electromagnet is constant on its locus.
The content of the invention
Task of the invention is to provide the imbalance compensation improved to some extent relative to prior art of laundry drum.
According to the present invention, the task is by the family expenses device for care of laundry items object according to corresponding independent claims
Have with method to solve.
Home appliances for care of laundry items object of the invention include can be rotated around a pivot center, be used for
Receive the laundry drum of clothing object.Additionally, the home appliances includes at least one imbalance compensation device, the uneven benefit
Repaying device has housing, and multiple separate compensating element,s are included and are arranged in other words in the housing in which can move.Imbalance is mended
Repaying device includes magnetic field generation device, and the magnetic field that can be acted to compensating element, is produced by the magnetic field generation device.
Observed along azimuth (atzmutaler) direction, the magnetic field can be produced in the way of the rotating in other words of dynamically changeable.Especially
Its, along around laundry drum pivot center rotate direction observation, specific azimuth position in the way of rotating and by
This produces the magnetic field acted to compensating element, in the way of not completely closed rotating.
Basic conception of the invention is, when the rotating speed of laundry drum is less than the reference rotation velocity of the laundry drum, to pass through
The magnetic field generation device is produced in the orientation angle segment observed around the pivot center of laundry drum and produces work to compensating element,
Magnetic field.Thus, such magnetic field constructs only in the section of the pivot center on laundry drum, i.e. in specific side
Constructed on azimuth position, and be therefore called section magnetic field for short.The magnetic field is with least respective compensation unit in compensating element,
What the mode that part is acted in terms of rotary speed of these compensating element,s around the pivot center of laundry drum was produced.It is described
Changing around the azimuth position for rotating end on observation for section is coupled with the rotary speed of laundry drum.Thus, magnetic field produces
Device is configured to, and magnetic field is partly produced in specific orientation angle segment, and the magnetic field acts to compensating element, is used
Kept in the position of compensating element, wherein, dynamic magnetic field produces to be associated with the rotary speed of laundry drum.Thus, one
Determine in degree, this range selector " continuing to vacillate " along azimuth direction in magnetic field enters according to the rotary speed of laundry drum
OK.Thus this also imply that, in the case where rotating speed is improved or rotating speed is reduced, the range selector " continuing to vacillate " in the magnetic field accelerates
Or slow down.
By the configuration of home appliances, can be right in the low and precritical range of speeds in a very simplified manner
Compensating element, is positioned with method in the desired manner.Then, thus also enable in particular to make the compensating element, not with the not phase
The mode of prestige is so moved so that if these compensating element,s may be exacerbated even more being produced in laundry drum by clothing object
Raw imbalance, such as this is known when in the case of without this configuration especially when the operation in subcritical speed scope.Just
It is that in the range of speeds below or equal to reference rotation velocity, this causes the bigger abrasion of the support of laundry drum, and especially
It causes with undesirably violent noise.
It is preferred that, reference rotation velocity is a rotating speed of the pre-determining of laundry drum and can be asked for by testing.It is preferred that, ginseng
Such rotating speed that rotating speed is laundry drum is examined, from the rotating speed, for the compensation matter of the imbalance compensation device of equilibrium establishment
Amount reliably and automatically moves to and unbalance mass, --- diameter on laundry drum --- on opposite side.Should
Rotating speed especially with imbalance compensation device and its compensation quality structure on design and friction effect and with by by injustice
Power caused by the rotation of vibration, gravity and laundry drum that weighing apparatus causes, being acted to compensation quality is relevant.Thus, family
A particular advantage with the configuration for being provided of utensil is, even if will not natively cause compensation quality in laundry drum
In the case of the relatively slow-speed of revolution --- i.e. less than or equal to reference rotation velocity --- for reliably automatically moving, it is also possible to cause uneven benefit
Repay uneven reduction in other words because produced by proposed dynamic magnetic field provide it is one additional, compensation quality is produced
The magnetic force of effect, the magnetic force can cause compensation quality for the movement required by imbalance compensation.
Here, azimuth also is understood as the pole of any of the plane (x/y plane) formed by imbalance compensation device
Angle, the plane perpendicular to laundry drum pivot center, when the point is given in polar angle coordinate system.Additionally, azimuth side
To the direction for illustrating polar angle, the direction is oriented along around the circular curve track of polar angle coordinate origin, and edge is enclosed in other words
Point in the direction that rotates around the pivot center of laundry drum.Additionally, orientation angle segment --- variable magnetic field is in the azimuth area
Produced in section --- the sector with the midpoint angle less than 360 ° of pre-determining also is understood as, it is especially fan-shaped in radially
Outside region, wherein, the sector is in the plane formed by unbalancing device, and the fan-shaped center of circle is clothing
The intersection point of the pivot center of roller and the plane formed by unbalancing device.

In the embodiment explained --- in the embodiment described in which, take and be in and be less than with the electromagnet 25 to 32 of rotation
Or in the range of speeds equal to the reference rotation velocity of laundry drum 3 --- in, this aspect is realized by following manner：
According to clothing object 35 particularly by uneven determining device 36, especially in terms of azimuth position and radial orientation angle size
Identified imbalance, compensating element, 20 is taken in the position for making the imbalance at least reduce.Therefore, in particular according to compensation unit
The instantaneous position of part 20, makes electromagnet 25 to 32 work and not work for the magnetic field of electromagnet produces.Thus, produce
The azimuth position change in magnetic field, its mode is that the electromagnet 25 to 32 for making rotation is individually turned on or off.Then, such as
Fruit compensating element, 20 is brought into azimuth position desired, relative to clothing object 35, then these compensating element, quilts
It is maintained in the position, its mode is, electromagnet or adjacent electromagnet 25 to 32, especially those are opposite with clothing object
Electromagnet be continuously kept in action and thus produce magnetic field state in, it is possible thereby to keep the position.Other electricity
Magnet 25 to 32 also keeps not working in further rotating, and thereby does not produce magnetic field.But, magnetic field is then also in section side
Parallactic angle aspect is vacillated, because the electromagnet 25 to 32 for working is rotated further, more specifically with the rotary speed of laundry drum 3
It is rotated further.Here, what position is changes of magnetic field that is dynamic, carrying out in azimuth have with difference thus according to compensating element, 20
Mode is carried out.
Until reach compensating element, 20 for compensate as produced by clothing object 35 it is unbalanced, around rotation
On the azimuth direction of axis A, 180 ° ad-hoc location position of staggering especially with respect to clothing object 35, just as described above
Electromagnet 25 to 32 is individually controlled, so that compensating element, 20 reaches this desired opposite position staggered in principle
Put, and compensating element, then proceedes to be maintained in the position.Thus, in the first stage, by the changes of magnetic field on azimuth
Compensating element, 20 is caused relative to laundry drum 3, targetedly relative motion, is not this in the case of second stage
Sample, but keep what the position for the laundry drum 3 of rotation of compensating element, 20 was fixed by rotating in second stage
Position.
I.e., in this embodiment, on the one hand the section in this magnetic field is vacillated then also is carried out before following state, in the shape
Under state, compensating element, 20 is opposite with clothing object 35, because thus individual other electromagnet 25 to 32 is then along the direction point that rotates
It is one after the other not controlled, to be switched on or to turn off, and thereby produce or do not produce corresponding magnetic field.On the other hand, exist
Vacillating for magnetic field is carried out by its own rotation after the position for reaching compensating element, 20.
If on the other hand be configured with an embodiment, in the case of the embodiment, electromagnet 25 to 32 not with
Laundry drum 3 is taken with rotation together, and therefore position is fixedly placed in housing 2, then may be otherwise by edge around
The electromagnet 25 to 32 of the direction to mutually following that rotate of pivot center A is turned on and off to produce the range selector in magnetic field to swim
Move.
It is also noted that in the diagrams of figure 3, compensating element, 20 is arranged with being still spaced from each other spacing, so as at this
In other words in position, the imbalance as caused by clothing object 35 can't be compensated fully the position state of sample.Therefore preferably, compensation
Element 20 is brought into mutual closer proximity, and this has by electromagnet, especially electromagnet 25,26 and 31 and 32
Targetedly control to realize.In the optimum position for carrying out maximum compensation to the imbalance as caused by clothing object 35
In, compensating element, 20 then mutually reclines, and is then mutually maintained at by the magnetic field of electromagnet 25 and 32 and is rolled relative to clothing
For cylinder 3 in fixed position.
