Description
Technical Field
The invention relates to a laundry treatment appliance, in particular a washing machine or a washer-dryer, having a housing, a lye container movably arranged in the housing, and a laundry drum which is arranged rotatably in the lye container about a transverse axis extending transversely to a vertical axis of the laundry treatment appliance.
Background
A washing machine, referred to as a front-end loader, comprises a housing and a lye container movably arranged in the housing, in which lye container a laundry drum is rotatably arranged about a transverse axis extending transversely to a vertical axis of the laundry treating appliance. The laundry drum is driven directly or indirectly via a transmission element, such as a belt or a chain, by means of an electric motor, which is rigidly coupled to the lye container. Usually, the lye container is suspended in the housing by a spring element and supported from below relative to the housing by a damper assembly.
The damped support of the lye container in the housing prevents vibrations of the lye container during operation of the washing machine from being transmitted undamped to the housing. Such oscillations of the lye container occur during operation of the washing machine, in particular during the spin-drying operation, as a result of an uneven distribution of the laundry in the rotating laundry drum or an imbalance resulting therefrom.
It is known to achieve a damped support of the lye container in the housing by means of a damper with a constant nominal damping force, in particular a so-called friction damper. These dampers are mounted at least partially below the lye container and reduce the amplitude of the vibration of the lye container within resonance. The reduction of the amplitude of the vibration within the resonance becomes stronger as the damping force of the damper increases. However, the sound level generated by the washing machine at the maximum rotation speed of the laundry drum also increases with the increase in the damping force of the damper. For this reason, the current choice of dampers is a compromise between a reduction in the amplitude of the vibrations within the resonance and a reduction in the sound level in the case of maximum rotational speed of the laundry drum.
DE 69829686T 2 discloses a washing machine having a frame, a drum mounted on the frame, springs holding the drum flexibly relative to the frame, an adjustable device with a controllable damper connected between the frame and the drum, and a control device for activating the adjustable device for producing a high damping state for a predetermined state of the drum.
Disclosure of Invention
The aim of the invention is to reduce the noise generation caused by the operation of the washing processing device.
This object is achieved by the independent claims. Advantageous embodiments are described in the following description, dependent claims and the drawings, wherein these embodiments can each be used individually or can mutually form an extended, particularly also preferred or advantageous aspect of the invention in different combinations.
The laundry treatment appliance according to the invention, in particular a washing machine or a washer-dryer, comprises a housing, a lye container movably arranged in the housing, and a laundry drum which is rotatably arranged in the lye container about a transverse axis extending transversely to a vertical axis of the laundry treatment appliance. The lye container is supported relative to the housing by at least two adjacent damping units arranged spaced apart from each other about the transverse axis and by at least one further damping unit arranged circumferentially offset relative to the adjacent damping units about the transverse axis, the further damping unit having a constant damping characteristic, at least one of the adjacent damping units having an adjustable damping characteristic.
According to the invention, the lye container is supported relative to the housing by means of a damper assembly in which at least one damping unit having an adjustable damping characteristic is combined with at least one damping unit having a constant, i.e. non-adjustable, damping characteristic. The lye container is supported on one side by at least one damping unit with adjustable damping properties and on the other side only by one or more damping units with constant damping properties relative to the housing. The damper assembly according to the invention can thus be optimally adapted to the respective use case by selecting the type of the respectively used damping unit, in order to reduce the generation of operational-related noise of the laundry treatment appliance to the greatest possible extent. The arrangement according to the invention of the adjustable damping unit on only one side of the lye container can be realized more cost-effectively than a damping assembly as follows: in the damping assembly, all damping units are equipped with adjustable damping characteristics.
At least one damping unit with an adjustable damping characteristic or damping force can be actuated in such a way that, at certain rotational speeds of the laundry drum (at which no resonant vibrations occur), a lower damping force is generated by the damping unit and, in at least one rotational speed range (at which resonant vibrations occur), a higher damping force is generated. In particular, it is thereby prevented that, in the case of the maximum rotational speed of the laundry drum occurring during the spin-drying process, the lye container is coupled to the housing with an excessively high damping force, which may lead to high noise generation. Alternatively, a damping force optimally adapted to the respective vibration state of the lye container can be generated by a damping unit with an adjustable damping force.
The damping force of the adjustable damping unit can be adjusted as a function of the vibration state of the lye container, which is currently detected by the vibration sensor device of the laundry treatment appliance, wherein the vibration state can preferably be detected by means of a position-velocity detection sensor device or an acceleration detection sensor device, which detects the position, velocity or acceleration of the lye container. Alternatively, for example, rotational speeds (in the case of which vibration resonances occur) can be determined empirically beforehand and taken into account in the framework of the time control of the processing program and used for actuating the adjustable damping unit. The adjustable damping unit may for example be a magnetorheological damping unit, the damping characteristics or the damping force of which may be adjusted by the generation of a magnetic field.
The casing is an appliance casing of the washing processing appliance. The damping unit can be supported on a side wall, a rear wall, a front wall or a bottom of the housing, the front wall having a loading opening formed thereon.
The lye container is movably arranged within the housing such that it is mechanically decoupled from the housing to a certain extent. In this case, the lye container can additionally be suspended from the side walls, rear wall, front wall or lid of the housing by means of spring elements.
The laundry drum is arranged in the lye container rotatably about a transverse axis, which can extend in particular perpendicularly to the vertical axis or horizontally of the laundry treatment appliance. Such a configuration occurs in particular if the laundry care appliance is in the form of a front-end loader having a substantially horizontal drum rotation axis. However, the invention can also be used for laundry treatment machines with a drum axis of rotation that is inclined with respect to the horizontal.
The arrangement of adjacent damping units spaced apart from each other with respect to the transverse axis means that one of these damping units is arranged closer to the front wall of the housing and the other damping unit is arranged closer to the rear wall of the housing. Adjacent damping units can act on the lye container at the same height or at different heights. Two or all adjacent damping units may also have adjustable damping characteristics.
The further damping units are arranged offset in the circumferential direction with respect to the transverse axis and thus with respect to the outer casing of the laundry drum with respect to the adjacent damping units. The fact that the further damping unit has a constant damping characteristic means that the damping characteristic or the damping force of the further damping unit is not adjustable and remains substantially unchanged under load. The laundry care appliance may also have two or more damping units with constant damping properties, which are respectively arranged circumferentially offset relative to adjacent damping units.
According to one advantageous configuration, each of the adjacent damping units comprises an adjustable damping characteristic. The rotation of the lye container about the transverse axis and about the vertical axis can be reduced in particular by adjusting the damping characteristics or the damping force of the adjustable damping unit in such a way that the adjustable damping unit is independently actuated or adjusted.
According to a further advantageous embodiment, there are only two adjacent damping units and only one further damping unit. In tests it has been demonstrated that the individually arranged further damping units have no significant influence on the movement behavior of the lye container. By means of the arrangement of two damping units arranged at a distance from one another and having an adjustable damping characteristic on one side of the lye container and the arrangement of a single further damping unit having a constant damping characteristic on the other side of the lye container, it is possible in a simple manner and with a small overall number of damping units to reduce the rotation of the lye container about the transverse axis and about the vertical axis. Furthermore, the damping assembly offers the possibility of: the differently acting damping forces are realized according to the type of unbalance that currently exists. Furthermore, the small overall number of damping units results in a reduction of the installation space required for the damping units. Furthermore, the risk of the lye container jumping within resonance or in the supercritical range in the case of an adjustable damping unit switch-off or in the case of a current loss is reduced by maintaining the damping unit with constant damping properties.
According to a further advantageous embodiment, a further damping unit acts on the lye container in the middle. Thereby, the further damping unit may allow a rotation of the lye container about the lateral axis and the vertical axis, which rotation may be caught or compensated for on the other side of the lye container by the at least one adjustable damping unit.
According to a further advantageous embodiment, the adjacent damping unit is arranged upstream of the further damping unit with respect to the direction of rotation of the laundry drum during the spin-drying process, such that a section of the rotating laundry drum which passes the adjacent damping unit at an elapsed time point passes the further damping unit at a later elapsed time point without reaching the height of the transverse axis in an intermediate time between said elapsed time points. It therefore occurs, for example, that, in the case of a rotation of the laundry drum to the left during the spin-drying process with respect to the front view of the laundry treatment appliance, an adjacent damping unit is arranged on the left side of the lye container. In contrast, in the case of a rotation of the laundry drum to the right during the spin-drying process with respect to the front view of the laundry treatment appliance, the adjacent damping unit is arranged on the right side of the lye container. At least one damping unit may be adjustable by an adjacent damping unit.
According to a further advantageous embodiment, the laundry treatment appliance comprises at least one electronic component unit for actuating at least one damping unit with an adjustable damping characteristic. The electronic component unit may be realized by the appliance electronic component or may be arranged separately from the appliance electronic component. The electronic unit can be connected to the vibration electronics of the laundry treatment appliance in order to detect the current vibration state of the lye container and to actuate the adjustable damping unit as a function of the signal of the vibration sensor device.
The adjustable and non-adjustable damping units may be implemented as linear dampers as well as rotary dampers. Furthermore, in the laundry treating appliance, the linear damper and the rotary damper may be combined with each other. For example, the adjustable damping unit can be designed as a rotary damper and the non-adjustable damping unit as a linear damper, or the adjustable damping unit can be designed as a linear damper and the non-adjustable damping unit as a rotary damper. This has particular advantages: the damping arrangement can also be optimally adapted to the vibration behavior of the lye container in the laundry treatment appliance, since the linear damper and the rotary damper have their damping action in different directions.
The invention is not limited to the illustrated combination of features of the independent and dependent claims. Furthermore, additional possibilities arise: the individual features are combined with one another, in particular when the individual features are derived from the claims, the following description of the exemplary embodiments or directly from the drawings. Furthermore, the claims should in no way limit the scope of protection of the claims to the embodiments illustrated, by the use of reference signs to the figures.
