Abstract

Programmable drum washing machine, the washing drum of which is rotatably arranged in a detergent tank, with a device for spraying clean water and / or detergent on the laundry contained in the washing drum and an opening washing drum filling opening located on the front side, which can be closed by a bowl-shaped porthole door, projecting into the filling opening of the washing drum, a line of the spray device leading into the area of the washing drum. filling opening, characterized in that the outlet end (9) of the liquid line (8) of the spray device is oriented towards the concave part (4 ') of the porthole door (4) at an angle such whether the liquid jet reaching the bowl-shaped part (4 ') is split or fan-distributed and achieves a spray jet direction oriented towards the inner casing of the washing drum (2) or the washing ring (5) who is s solidarity.

Description

The present invention relates to a programmable washing machine with

  drum comprising a washing drum rotatably arranged in a detergent tank, with a device spraying clean water and / or detergent on the laundry contained in the washing drum and a filling opening for the washing drum located on the front side, which can be closed by a bowl-shaped porthole door, projecting into the filling opening of the washing drum, a pipe of the spraying device terminating in

  the filling opening area.

  Patent DE 39 15 345 Ai describes a programmable drum washing machine with a washing drum rotating in a detergent tank, in which the working liquid is sprayed or injected directly inside the washing drum, and thus on the laundry therein, by a liquid line terminating in the area of the filling opening of the washing drum. The object of the present invention is to further standardize the spraying and thus the humidification of the laundry. This object is obtained according to the present invention in that the outlet end of the liquid line of the spraying device is oriented towards the concave part of the porthole door at an angle such that the jet of liquid reaching the shaped part bowl is shared or fan-shaped and achieves a direction of spray jet directed towards

  the inner casing of the washing drum or the

  washing water which is integral therewith.

  An advantageous improvement of the object of the

  present invention is characterized in that a depres-

  concave sion is formed in the shell of the bowl-shaped part of the porthole door and in that its deepest point forms a straight line with the end

of the liquid line.

  The advantages which can be obtained with the present invention lie inter alia in the fact that

  the laundry fluid 14 age for laundry undergoes a distribution

  tion or a very fine dispersion and is sprayed wide-

  fan on the laundry Uniform wetting of the laundry over the entire width of the drum

washing is thus ensured.

  Various other features of the invention

  moreover emerge from the detailed description which

follows.

  Forms of realization of the object of the invention-

  tion are shown, by way of nonlimiting example,

to the accompanying drawings.

  Figs 1 and 2 are schematic sections of drum washing machines comprising a device

  liquid spraying according to the invention.

  Fig 3 is a partial section of a detail of the liquid spraying area in enlarged representation. The drum washing machine according to fig 1 has a detergent tank 1, in which a perforated washing drum 2 with alternating movement is arranged so that it can be rotated. The washing drum 2 has a filling opening 3 on the front side, which is sealed by a porthole door 4 in the form of a bowl A contiguous washing ring of the drum casing is located inside the washing drum 2 A clear water pipe , controlled by a valve device 7, is designated by 6 The clear water pipe is part of a direct spraying device 8 conveying the washing and rinsing liquid to the washing drum 2, and the outlet end of which 9 ends in the area of

  the filling opening 3 of the washing drum

  above the bowl-shaped part 4 'of the window door 4 The outlet end 9 of the pipe 8 is then oriented towards the bowl-shaped part 4' of the window door 4, suitably under an angle such that the jet of liquid arriving there on a hollow (concave) surface suitably shaped in the bowl-shaped part 4 'is divided or fan-shaped It is appropriate to provide in the envelope of the shaped part bowl 4 'of the window door 4 a concave depression 10, the deepest point 11 of which forms a straight line with the outlet end 9 of the

  direct spray line 8 The incoming water jet

  vant in depression 10 is thus deflected accordingly

  and directed in an oriented and fan-shaped fashion

washing water 5.

  Fig 2 shows a drum washing machine in which the working liquid is led in

  circuit To this end, a circulation pump 14

  grammable is inserted in the liquid line 8 '.

  The laundry watering operation 5 takes place from the

as previously described.

Claims (2)

RESELL ICATIONS   1 programmable drum washing machine, the washing drum of which is rotatably arranged in a detergent tank, with a device spraying clean water and / or detergent on the laundry contained in the washing drum and a washing drum filling opening on the front side, which can be closed by a bowl-shaped porthole door, protruding into the filling opening of the   washing drum, a line of the spraying device   sation ending in the area of the opening of rem-   pleating, characterized in that the outlet end (9) of the liquid line (8) of the spraying device is oriented towards the concave part (4 ') of the porthole door (4) at an angle such that the jet of liquid reaching the bowl-shaped part (4 ') is shared or fan-shaped and achieves a   spray direction directed towards the   inner cover of the washing drum (2) or of the   washing water (5) which is integral therewith.   2 Drum washing machine as claimed   tion 1, characterized in that a concave depression (10) is formed in the casing of the bowl-shaped part (4 ') of the porthole door (4) and in that its   deepest point (11) forms a straight line with the end   mity (9) of the liquid line (8 or 8 ').
