The invention! «Extends to a facility to compensate for unwanted effects of the circulating, elastically mounted parts of a spin dryer, with a borrowing container firmly connected to your revolving part to accommodate the balancing mass that changes the center of gravity during rotation,

With a spin dryer, the drum runs because the laundry is never inserted exactly centered canoe, always with a more or less large side Rash, causing the storage of the drum is exposed to permanent self-claims, which can take on considerable proportions.

In addition to numerous other suggestions that have already been made for losing the task have been done to at Spin laundry with a centric drum rotation, balancing compounds have become known, which are in a container firmly connected to the rotating part and the center of gravity change independently during circulation. In the case of the known proposals, they serve as a leveling compound !! Ring weights or cylindrical vessels or tubes with a partial filling z. B. from mercury, which in lanes parallel to the floor of the laundry drum 1) Let go, so that your movement starts right at the beginning dci Troinmeldrehiing begins.

In the case of the invention, the in the receptacle should be in the form of balls or a partial mercury filling arranged balancing mass only at a certain speed of rotation of the laundry drum Let it move out of the rest position near the vertical axis of the rotating parts in order to to compensate for any Uiiwuchteii, and after completion des Tronnnehunlauf.es back to their original Return to the rest position. The unbalance compensation and thus the central and balanced one The position of the balancing mass should therefore only be at a level above the negative resonance number of the system Speed occur, so that the operation of the centrifuge up to üIkt the critical speed range addition does not deteriorate.

The invention solves the problem essentially in such a way that the receptacle forming Doppelwatuligc bottom of the centrifugal drum has a conical recess for receiving the leveling mass, which has such a slope, that the balancing mass is only above the resonance range takes effect.

Since the conical depression must expediently have a wall that is as steep as possible in order to achieve the intended To achieve an effect, it naturally requires a space requirement, which may be too can lead to constructive difficulties.

The invention therefore also provides for the arrangement of two conical surfaces of different inclinations in the up-device to compensate for imbalances in a spin dryer

Further features of the invention and details

the advantages achieved by the same result from the following description of the drawings illustrated embodiments.

I ⁷ Ig. i shows a schematic section through a spin dryer with an additional mass system consisting of two masses according to the invention;

Fig. 2 shows a detail of an embodiment according to the principle of FIG. 1 with a liquid as additional mass system.

According to Fig. 1 lxs stands the spin dryer from the Centrifugal drum 1, which with the motor 2 by the Shaft 3 is connected. This rotating part is opposite the intermediate floor 4 by the elastic Links S mounted elastically. The intermediate part is 4 arranged in the housing 6 in a known manner. The centrifugal drum 1 has a double bottom provided, si) that a container 7 is formed. In this As a mass system according to the invention, there are two containers Balls 8 arranged.

The laundry in the spin drum 1 has a certain imbalance. In operation, the two balls 8 thrown outward by centrifugal force. Your focus is now no longer in the axis of rotation and result in an additional imbalance, the resultant of which is caused by the

Claims (2)

Laundry caused imbalance is exactly the opposite. The rotating part is again in equilibrium and runs centrically, so that the elastic bearing consisting of the rubber bodies S does not is stressed by lateral stops. The setting of the balls 8 takes place automatically depending on the existing one Imbalance. The bottom surface of the container 7 consists of two Conical surfaces 9,10 or at least approximately conical surfaces of different inclination, such that the steeper Conical surface 9 inside forms a kind of pocket around the shaft 3 of the rotating part. Lie in peace the balls 8 always at the deepest point, i.e. in the pocket. The inclination of the inner conical surface 9 is like this chosen that the balls 8 only 1> ei a certain speed against their weight by the centrifugal force be thrown outwards. The outer conical surface 10 is curved in the circumference Bottom II of drum 1 over. In this way, the balls 8 can swing without abruptly at the outer circumference of the container 7 to hit «. As the speed at which the balls 8 take effect one will preferably choose one that is slightly above the resonance speed of the system In addition, the balls will adjust themselves so that their resultant opposes the existing imbalance is. Fig. 2 shows the same design for a liquid. The container 12 under the drum has a inner pocket 13 in which the liquid is in the idle state. Only lx-i exceed «one certain speed, the liquid will apply to the outer periphery 14 of the container 12 and set there in the same way as has been described in Fig. 1 for the balls.
