Definitions

  • the invention relates to a washing and / or drying device, especially drum washing machine, with a objects to be processed, especially laundry loadable Drum, which in a container, in particular a Suds container rotatably arranged and for processing the Objects is rotated by motor, the container in a housing is movably mounted, and with one operation controlling control device.
  • the invention is therefore based on the problem of a Specify washing and / or drying device by means of which the vibration-related problems mentioned above largely can be remedied.
  • a washing and / or Drying device of the type mentioned in the invention provided that means inside the housing for releasable fixing of the drum rotation caused by a load-related imbalance that can be excited to vibrate Container whose vibratory movement during the period of To largely prevent fixation, are provided.
  • the device has fixing means by means of which the container can be fixed and on it Way can be prevented from swinging.
  • fixing means by means of which the container can be fixed and on it Way can be prevented from swinging.
  • the means for fixing the container are designed and / or arranged such that the vibrating containers from a predetermined vibration-related Deflection from the rest position is fixed. Because for Eliminating the resonance problem, it is sufficient if the container is then fixed when the drum speed approaches the resonance speed, which is reflected by the corresponding Deflection expresses.
  • the means can be advantageous be arranged so that they grip, if the container just the appropriate deflection experiences, that is, that the means as passive Means are formed.
  • the means via a control element are controllable, which is dependent in particular of a detection result (drum speed or another Size) of a detector element detecting the deflection controls the funds. So these are active Agents that actively secure the container, these means of course also independently of one Detection result of a detector element can work and controlled for example by a time component in this way can be that in the spin operation after expiry a predetermined time, after which experience has shown the speed approaches the resonance speed.
  • the control device can act as a control element to serve.
  • the means are designed in this way and / or arranged that the fixed container if there is an imbalance that acts on the agent predetermined from the drum rotation Force or a moment is releasable.
  • the container comes off or will be solved with particular advantage if the unbalance force exerted on the remedy will pass you by exceeds the agreed value, which of course is measured in this way is that the resonance range is left, so that after loosening, no impermissibly large vibration amplitudes may occur.
  • the mean over the Control element is controllable. So in this case the force that acts on the agent directly determines that means that the predetermined force that brings about loosening is not determined by the construction of the agent itself.
  • the control can of course also take place independently of force, for example by Timing control or speed-dependent such that after Expiry of a predetermined time, after which it is certain that the resonance speed is exceeded is solved.
  • the means as permanent magnetic or electromagnetic means are formed, these both can act as both passive and active agents.
  • the permanent magnetic means be designed so that it can exert its magnetic force is actively transported to the container area, to fix this, the same applies to the electromagnetic Means, which are already controlled as active means must become.
  • the means are designed as clamping, locking or adhesive means are. It has proven to be useful here if the Means a first and a one arranged on the container fixed, in particular arranged on the housing second Have part.
  • Constructions are used, for example in the form of interlocking wedge-shaped clamping elements, or but a Velcro tape that is attached to both the housing and the Container is attached and when the two are put together Parts provides a sufficient connection.
  • an adhesive training in the form of a suction cup, i.e. one with Vacuum working means is conceivable.
  • the locking means can any latching connection that a safe intervention provides at the same time solvability.
  • FIG. 1 shows a washing and / or drying device 1, comprising a housing 2 in which a containing a drum 3 Container 4 is arranged, which is only here sketchy representation.
  • the container 4 is shown in the Exemplary embodiment by means of spring suspensions 5 arranged swinging in the housing 2. If the drum is operational is rotated and one inside due to loading given unbalance, the container 4 leads accordingly Movements in the form of vibrations. Around especially in the resonance range, in which the vibrations have extreme amplitudes due to the resonance effect can prevent these vibrations are means 6 provided that serve to fix the container 4.
  • This Means 6 comprise a first attached to the outside of the container Part 6a and a fixed, in the example shown second part 6b attached to the housing 2.
  • both parts 6a, 6b are spaced apart. This means that cooperation is only possible if the container is in this direction of movement the distance experiences corresponding deflection.
  • the means 6 are both in their number and in their arrangement to choose that the vibrating system, i.e. the container, is securely fixed before moving in one direction the allowable amplitude, which then corresponds to Can cause damage.
  • the means 6 formed as an adhesive in Form of Velcro strips, which with appropriate deflection of the Attack the container together and so the container in the First fix the correspondingly deflected position.
  • the liability of the Velcro connection is limited, it is the Container possible, if that on the connection between parts 6a, 6b acting due to unbalance, those that increase as the spin speed increases Centrifugal force increases and exceeds the adhesive force, to loosen up.
  • FIG. 2 shows a device similar to that shown in FIG. 1 constructed washing and / or drying device, wherein on the one hand, another type of fixation device is provided, on the other hand, these funds are in another Direction of movement of the container provided.
  • This one shown means 7 is a permanent magnetic means consisting from a first attached to the outside of the container Part 7a, for example the permanent magnetic part, and one fixed on the top or bottom of the housing attached, e.g. B. made of magnetizable material second part 7b.
  • This is in the embodiment shown pot-shaped, the part 7a in Shape of a pin that engages in the closed pot. If the container now experiences a corresponding deflection, the pin-shaped part 7a begins to move and approaches the second with increasing deflection Part 7b.
  • the two are liable Parts 7a, 7b due to magnetic flux to each other and fix the container. Again, the connection is increasing a force between the parts 7a, 7b acting fixation possible. Due to the constructive training the means 7 is a fixation for every possible Direction of movement possible because the parts 7a and 7b adhere to both vertical and horizontal movements to each other.
  • FIG. 3 shows a further embodiment of a By means 8, which is designed here as a clamping means.
  • This consists of a projecting one arranged on the container cone-shaped first part 8a, which on its front end portion 9 tapered frustoconical is.
  • This is assigned a stationary on the housing arranged second part 8b, which has a recess 10 has, which in the front area with a inside tapering, large receiving opening 11 is provided.
  • This is also tapered towards the rear tapered area 12, which corresponds to the Area 9 of the first part 8a is formed.
  • FIG. 4 shows a further means 13 in the form of a Holding means.
  • This also consists of a first part 13a, which has a spherical at its free end Approach 14 is provided.
  • Part 13a is a fixed, assigned to the housing part 13b, which in a correspondingly large recess in its front area 15 has, which tapers inwards.
  • the recess 15 ends in a spherical cavity 16, which is somewhat is undercut.
  • This means becomes advantageous made of plastic, which allows easy snap-in, manufactured.
  • the invention is not based on the fixing means shown limited.
  • funds are in the form of, for example spring-loaded locking hook or the like possible, that is, there is an undercut on the container provided pin arranged on the housing Opposite is assigned which one is the undercut has engaging catch or the like for example spring-loaded or by means of an actuator can be operated to release the undercut.
