Definitions
- the present invention relates to a laundry treatment appliance, in particular a laundry treatment appliance with an active vibration damping system.
- a laundry treatment device such as a washing machine, a tumble dryer or a washer dryer typically has a tub (also referred to as a wash tub), a laundry drum rotatably mounted in the tub, and an electric motor for driving the laundry drum.
- the tub is held, for example via a plurality of vibration damper movable in the housing of the laundry treatment appliance.
- an unevenly distributed load applied to the circumference of the laundry drum can cause unwanted movements of the tub, which can lead to a movement of the same, but at least to an undesirable noise at a rigid coupling of the tub to the outer wall of the laundry treatment device.
- a laundry treatment device in which the inner unit via at least one spring, which is secured between the housing and preferably the upper portion of the tub, and at least one friction damper, which secures between the tub and the lower portion of a side wall or the bottom of the housing is suspended, vibrationally suspended.
- the springs and friction dampers form the vibration and damping system of the laundry treatment appliance.
- Friction dampers in their simplest form consist of an outer body (e.g., tube) and a plunger, preferably plastic, coaxially displaceable therein or coaxially therewith.
- a rubber-like, porous pad is inserted between the plunger and the outer body, which may be saturated with grease or a fat-like liquid. The object of this pad is to increase the friction between the plunger and the outer body and to convert the kinetic energy of, for example, a tub in frictional heat.
- This type of friction damper is also called “free-lift friction damper”.
- the properties of these friction dampers can be influenced by the choice of the contours of the friction surfaces and are substantially constant over the life of the laundry treatment device apart from natural aging processes.
- Such a free-lift friction damper is for example in the DE 40 14 166 A1 described.
- the EP 0 878 574 B1 discloses a method for actively dampening vibrations in a laundry treating appliance.
- the friction damper in this case contain a magnetorheological medium, the rheological properties (eg viscosity) can be changed by applying a magnetic field, so as to influence the damping properties of the friction damper.
- a speed deviation of the electric motor is detected and generates a control signal when a threshold value for this speed deviation is exceeded.
- This control signal generates a magnetic field inside the friction damper whose flux density is proportional to the actuating signal and thus to the extent of the rotational speed deviation.
- controllable friction dampers are not yet used as standard in laundry treatment equipment, since in a power failure their functionality is lost or severely limited because the magnetorheological Liquid without excitement is typically low viscosity and consequently can cause no or only low damping properties. Particularly in the case of large imbalances, in the event of a power failure due to the further rotation of the laundry drum, very great deflections of the tub can occur, which can lead to damage to the laundry treatment appliance and cause disturbing noises.
- the invention has for its object to provide a laundry treatment device with an actively controllable vibration damping, which ensures a safe leakage of the laundry drum even with a malfunction of the power supply.
- the laundry treating appliance includes: a laundry treating device having a rotatably mounted laundry drum, the laundry treating device being movably supported in a housing of the laundry treating appliance; an electric motor for rotationally driving the laundry drum; a controller for driving the electric motor, the controller being connectable to a power supply; at least one vibration sensor for detecting a vibration movement of the laundry treating apparatus; and at least one vibration damping device for damping a vibration movement of the laundry treatment device.

- the laundry treating appliance of the invention includes an actively controllable vibration damping system. This is only functional if the (engine) control and the vibration damping system are supplied with electrical energy. In order to prevent imbalance of the laundry treating apparatus in case of malfunction of the power supply (e.g., power failure), causing no damage to the laundry treating appliance, the vibration damping system is kept functional even in such a malfunction of the power supply.
- the vibration damping system is kept functional even in such a malfunction of the power supply.
