Description

The invention relates to a top loading drum washing machine.

  drum loading washing machine

  the top, inside the bodywork, of which is a

  sive provided with a loading opening, with mounted rotating in

  this a laundry drum provided with a filling opening for

  before being closed, washing machine in which a hopper of

  filling that extends from an additional loading opening

  shut up in the top panel of the body in the direction of the opening

  load of the laundry tub and in which the laundry tub is connected to the top panel of the bodywork by a cuff which

  surrounds the loading hopper on the inside facing side of the car-

bodywork.

  A washing machine of this type is known by the patent DE-A-

  22 33 692. In this known washing machine, a tube-shaped cuff which extends all around the loading opening of the laundry tub is linked to the upper face of said laundry tub. At its opposite end,

  this cuff is linked to the top panel of the washing body

  laundry in such a way that there is a liquid tight connection between the washing machine body and the washing tub. To facilitate the loading of laundry into the laundry drum, a filling hopper which extends towards the filling opening of the laundry drum is attached to the top panel of the washing machine body. The cuff surrounds the

  loading hopper on the side facing the inside of the car-

  bodywork. However, it has been found that a cuff with a characteristic

  flexible ristic frequently beats the filling hopper when

  the laundry tub oscillates. This not only leads to unpleasant noises -

  but still may cause deterioration of the cuff. In

  however when the cuff is rigid enough we avoid the bat

  of the latter against the filling hopper, but the

  these very high to the bodywork of the washing machine, which forces can cause vibration of the bodywork. The object of the invention is to arrange a drum washing machine of the type indicated in the introduction so as to avoid at the same time a beat.

  persistent cuff against the filling hopper and a transmission-

  high forces at the washing machine body.

  This objective is solved according to the invention by the fact that fixing means are provided on the face of the cuff facing the filling hopper and / or on the side of the wall of the hopper facing towards

  the cuff, which means of attachment, in the event of a flap of the cuff

  chette against the filling hopper generated by the oscillation of the washing tub, make a connection between the cuff and the wall concerned of the filling hopper. Thanks to this temporary connection resulting from contact between the cuff and the filling hopper, the flapping of the cuff is stopped. The forces transmitted to the body remain weak

  due to the generally flexible characteristic of the cuff.

  According to another embodiment of the invention, the transmission to the washing machine body of vibrating bforces coming from

  of the laundry tub is further reduced by the fact that the connection between the

  chette and the wall of the filling hopper is made in the area of the

  cuff which is essentially stationary in the horizontal direction.

  The connection between the cuff and the filling hopper can

  be obtained in a simple way by suction cups provided on the man-

  chette. When the cuff comes to beat against the hopper, the suction cups stick firmly to the smooth wall of the filling hopper, preferably made of an injection molded plastic, and thus make) a connection between the filling hopper and the cuff. Advantageously, the suction cups can be linked in one piece to the cuff. So no additional work is necessary to

the installation of suction cups.

  A connection between the cuff and the filling hopper can also be obtained by fixing means of the contact closure type which are arranged both on the filling hopper and on the cuff. Such fastening means may be projections in the form of buttons which, when the cuff flaps, are hooked together.

  in the others and thus fix the cuff to the filling hopper.

  The desired connection between the sleeve and the filling hopper and a reduced transmission of forces to the washing machine body are obtained by means of a sleeve comprising a wall part which

  extends essentially vertically, well-shaped, from a bulge

  mounting flange linked to the top panel of the body and is connected to a

  ) second mounting bead linked to the laundry tub by a part of link

  its at least substantially horizontal, in the form of a bellows.

  The invention is described below in detail using an embodiment shown in the drawings. These show:

  Figure 1, schematically a cross section of a washing machine

  top loading tumble laundry,

  Figure 2, an enlarged view of Part II of Figure 1.

  The laundry tub I is mounted to oscillate in a washing machine body 2. A laundry drum 3 is mounted to rotate inside the laundry tub itself. The laundry drum 3 has a filling opening 5 which can be closed by a two-part cover 4. The two cover parts 4 can be opened in the area of a loading opening 6 provided in the laundry tub 1, so that after having opened a cover 7 provided in the top panel of the body, opposite the loading opening 6 of the laundry tub, it is possible to load laundry into the laundry drum 3, or even take laundry

in said laundry drum.

  On the washing machine body 2 there is a hopper for

  pleating 8 which extends from the lid area 7 towards the loading opening 6 of the laundry tub 1. In the open position, the lid parts 4 come to bear on the free end of the filling hopper 8 and form with said filling hopper 8, a well through which the laundry can be introduced safely into the drum

laundry 3.

  To prevent washing liquid from escaping from the

  sive 1 in the washing machine body 2, a sleeve 9 is arranged

  between the upper face of the laundry tub 1 and the inner wall of the pan

  top level of the washing machine body 2. Besides its waterproofing function

  the cuff also has the task of largely isolating the washing machine body 2 from vibrations coming from the washing tub 1. This is obtained optimally when the cuff 9

  has a very flexible characteristic. However with a characteristic

  that very flexible, it may happen that the cuff 9, excited by the vibra-

  of the detergent tank 1, come and beat the filling hopper 8

  which is accompanied by noise. To avoid this persistent beating, the man-

  ) chette 9 has a particular conformation.

  In the embodiment of the sleeve 9 shown in Figure 2, a wall portion 1 1 in the form of a well which surrounds the hopper

  filling 8 follows a first mounting bead 10 linked to the pan

  top level of the washing machine body 2. This wall part 1 1 extends essentially vertically, or even substantially parallel to the filling hopper 8. The wall part 1 1 in the form of a well is

  connected via an essentially horizontal connecting part 12

  zontale to a second mounting flange 13 linked to the laundry tub 1.

  On the face of the wall portion 1 1 in the form of a well facing towards) the filling hopper 8 are fitted with suction cups 14. When the

  wall part 11, excited by corresponding vibrations of the tank.

  detergent 1, oscillates in the horizontal direction, the suction cups 14 come

  in contact with the smooth wall of the filling hopper 8 and stick tightly

  to this one. Thus the horizontal vibrations of the wall portion 1 1 generating beat noises are eliminated. Thanks to the bellows-shaped connecting part 12 the transmission of vibrations from the tank

  detergent 1 at the washing machine body 2 is largely avoided.

  since the connecting part 12 can be made with a characteristic

sufficiently flexible.

  A sleeve 9 of this type is characterized by a reduced transmission of forces to the washing machine body 2 without the bulk

  however important. In addition, it can be advantageously used.

  in connection with high spin speeds of the washing machine.
