A damper assembly, in particular for a washing machine, comprises at least one damper which causes a damping effect, in particular an active damper, which can be arranged between two components of the washing machine which are movable relative to one another and can each be connected thereto, a regulation unit which is in signal communication with the damper and is intended to regulate the damping effect of the damper, at least one determination unit, which is in signal communication with the regulation unit, for determining at least one input variable, wherein the regulation unit is designed to transmit a regulation signal to the damper in dependence on the at least one input variable, the damper is designed to variably define its damping effect in dependence on the regulation signal. In addition to the at least one active damper, at least one passive damper can be provided.

A frictional damper includes a housing having a longitudinal axis, a tappet which is movable along the longitudinal axis, a frictional unit for generating a direction-dependent frictional force on the tappet, wherein the frictional unit includes at least one friction lining lying rubbingly against the tappet, and a switching unit for variably setting the frictional force.

Frictional damper

A frictional damper is designed with a tubular housing having a longitudinal axis, with a tappet, which is displaceable in the housing along the longitudinal axis and is led out at an open end of the housing, with a frictional element lying against the tappet and with a cap attached to the open end of the housing with axial prestressing relative to the longitudinal axis.

A switchable damper comprises a housing having a longitudinal axis, a plunger displaceable along the longitudinal axis, a piston arranged between the housing and the plunger, a friction lining arranged on the piston and a switching unit, which is switchable between a blocking arrangement, in which the piston is blocked with respect to a displacement along the longitudinal axis, and a free-moving arrangement, in which the piston is released with respect to a displacement along the longitudinal axis.

Switchable damper

A damper includes a housing with at least one axially offset longitudinally extending guide channel for receiving a plunger of a piston assembly. The plunger is axially offset from a control rod extending through the housing and the piston assembly. A coil spring surrounds the housing and extends between a hemispherical cap of the housing and the piston. The plunger includes a friction pad which engages the guide channel of the housing to provide frictional inter-engagement for the damper. In one embodiment, the housing includes a pair of axially offset guide channels and the piston assembly includes a pair of axially offset plungers which extend within a pair of guides of the housing. One of the plungers includes a linear sensor which provides signal information for use by a washer control circuit.

A displacement sensor modulefor mounting on a telescopic-type damper, a damper/detector assembly including such a displacement sensor module and a telescopic-type damper, and a household appliance including such a damper/detector assembly is provided. The displacement sensor moduleincludes at least one coil element, an electronic detection unitconnected to the at least one coil elementand adapted to detect an impedance change of the at least one coil element, and a coil housingfor receiving and additionally or alternatively a coil supportfor supporting the at least one coil elementand for supporting the electronic detection unit. The displacement sensor moduleis adapted to be mounted on a telescopic-type damper, wherein in particular the housingor supportis adapted to fit over a portion of a pre-assembled damper

In a damper for spin-drying washing machines, it is provided, with a view to amplitude-dependent damping behaviour being obtained accompanied with manufacture at a low cost, that a frictional damping unit, which is disposed inside a casing, comprises an at least sectionally bare and elastic frictional damping lining for producing a given frictional damping effect, and at least one stop element which is stationary in relation to the casing and turned towards the at least one frictional damping lining, with the at least one stop element being designed for direct cooperation with the at least one frictional damping lining.

Damper

With a method for determining the load of a washing machine, the load can be determined in a simple and exact manner in that the load is calculated by a comparison between suspension forces of the at least one suspension element and damper forces of the at least one damper with a non-linear characteristic in the unloaded and loaded state of the washing machine.

In a damper, in particular for spin-drying washing machines, it is provided, with a view to improved solidity and noise behaviour of the damper, that at least one buffer stop is disposed between at least one piston and at least one stop element, the buffer stop comprising at least one flexibly pliable buffer stop element which is integral with the at least one piston or the at least one stop element.

In a damper, in particular for spin-drying cylinder washing machines, it is provided, with a view to obtaining low-noise and low-wear guidance of a tappet in a casing, that the damper comprises a guiding damping unit which damps any deflections of the tappet in the radial direction and centers the tappet in the casing.
