Description

Washing machine with mounted top-loading drum

  horizontally in a laundry tub The invention relates to a washing machine comprising a top-loading laundry drum which is mounted at least substantially

  horizontally in a laundry tub as well as a storage device

  born from fresh water or detergent bath which is directed directly into the washing drum. In known washing machines of this type (DE-C-604 415), fresh water or the detergent bath is introduced directly into the washing drum via a hollow shaft and wets from above the linen which is inside the drum In order to obtain on the one hand a regular wetting of the linen and on the other hand a homogeneous distribution

  detergent introduced quickly with water, the laundry is stirred for

  during the wetting process by rotating the linen drum

  ge As it is supported on both sides by bearings, a known laundry drum of this type can only be loaded by the

above.

  In current washing machines, the mechanically driven washing drum can reach rotation speeds> 1000 l / min at the time of spinning, the bearings of the drum must be very stable, flexible and perfectly aligned with each other Plain plain bearings such as those used in known washing machines are not suitable for

such a case.

  These requirements considerably limit freedom of agency.

  in terms of construction Furthermore, the resources to be put

  used to achieve a central liquid inlet are very important

  aunts; indeed, for the liquid supply, a swivel connection is required in all cases, the mounting and sealing of which are suitable for high spin speeds. In addition, the rolling bearing must be protected against detergent which is aggressive For all these reasons, no action has so far been taken on proposals to introduce the detergent bath directly into the drum of a washing machine.

top loading ge.

  The object of the present invention is to arrange a washing machine

  of the type indicated in the introduction so as to allow an introduction

  direct operation of the laundry bath without having to bear otherwise

  the disadvantages mentioned above.

  The problem is solved according to the invention by the fact that the drum is only supported on one side and that the supply device

  of water is arranged in the cheek located opposite the bearing The

  cantilevered floor of the laundry drum with a bearing on one side allows the water supply device to be available at low cost

  cool or detergent bath in the cheek opposite the landing.

  There are also known devices for supplying fresh water or detergent bath (for example EP-A 239 025) which endeavor to bring fresh water or detergent bath inside the washing drum through the perforations of the outer wall thereof These devices have also been applied to loading washing machines

  from above it has been found that the effectiveness of wetting and watering

  laundry is not perfect The application of the invention makes it possible

  on the other hand, to obtain an improvement on both counts.

  In accordance with an improvement of the invention, the device

  positive water supply comprises at least one nozzle whose jets are directed onto an area of the drum which is normally occupied by the

linen placed in it.

  In accordance with another improvement of the invention,

  to obtain very intensive contact between the laundry and the detergent

  old dissolved in the washing bath, the water supply device is re-

  linked to a drain opening arranged in the lower part of the laundry tub via a circulation pipe Thus, the laundry bath can be put into permanent circulation during the

  wash and returned repeatedly to the laundry.

  The invention is described below using an exemplary embodiment

sation shown in the drawing.

  The drawing shows schematically the laundry drum 2 which is mounted horizontally in a laundry tub 1 of a washing machine not shown The laundry tub 1 has on the side

  left a stable bottom 6 in which is mounted a bearing 5 with horizontal axis

  zontal The axis 7 of a laundry drum 2 driven from the outside by

  via a belt pulley 8 is mounted rotating in the pa-

  link 5 A device 3 for supplying fresh water or detergent bath is placed in the right wall of the laundry tub and is substantially coaxial with the bearing 5 of the drum 2 The outlet of the device

  of water supply 3 is directed towards the inside of the laundry drum 2 through

  towards a cut 4 in the cheek 9 of said drum 2 The jets 10 which escape from the water supply device 3 wet the laundry 11 which

  located inside the laundry drum 2.

  Particularly advantageously, but not shown

  In this case, the water supply device 3 can include one or more nozzles which direct the water jets 10 towards particular areas of the laundry drum 2 so that the laundry is soaked.

direct and intensive.

  A discharge orifice 12 is disposed in the bottom of the tank

  detergent 1, opening through which the liquid introduced into the tank and the

  that drips from the laundry can be drained Not shown

  smelled, devices allowing the evacuated detergent bath to circulate and bring it back to the water supply device 3 can be

  provided on the outside of the laundry tub 1.

  The detergent bath can thus be put back on several times

  culation and water the laundry intensively.
