Embodiment Construction

[0043] figure 1The washing machine according to the illustrated embodiment has a lye container 1 in which a drum 2 is rotatably arranged and can be driven by a drive motor 14 . The axis of rotation 3 of the drum 2 points forward and upwards at a small angle (for example 13°) from the horizontal position, thus enabling easy access to the drum 2 and viewing of its interior. The washing blades 4 enable distribution of the washing 7 as the drum 2 rotates. The bucket 5 enables an enhanced rinsing of the clean laundry 7 with water 6 .

[0044] exist figure 1 In the embodiment shown, the heating device 16 is mounted on the outside of the lye container 1 and the drum 2 . figure 1 The shown heating device 16 is especially capable of supplying hot air or steam.

[0045] As an alternative, the foam introduced in step b) of the method described above and produced by the rotation of the drum 2 along with the washing 7 can be heated by the heating device 13 arranged at the bottom of the...

Abstract

The invention relates to a method for the treatment of laundry (7), having a washing lye in a washing machine comprising a lye discharge system (18) disposed on the base of a lye container (1), a pivotally supported drum (2), and a heating device (13, 16) for the direct heating of a load (a1) of laundry (7) containing the washing lye, the method comprising the steps of: a) adding the washing lye to the load (a1) in an amount (a2) smaller or equal to an amount (a3) required for saturation of the laundry (7) with water ('saturation amount'), and wetting the laundry (7); b) heating the wetted laundry (7) by means of the heating device (13, 16); and c) adding water at a temperature Tw of no more than 40 DEG C for rinsing the washing lye from the laundry (7). The invention further relates to a washing machine suitable for carrying out the method.

Description

technical field [0001] The invention relates to a method of treating laundry in a washing machine and a washing machine particularly suitable for carrying out said method. Background technique [0002] Using known washing methods, the laundry is treated with a certain amount of water sufficient to saturate the laundry and an additional minimum amount of free fluid, usually two to three liters, which makes the fluid absorbed by the laundry and the free fluid Material exchange is possible between fluids. In this way, in particular, heat transfer between the heater heating the free fluid and the washing can take place. The setting of the water quantity is generally determined on a case-by-case basis by a suitable method for adjusting the water level in the drum and matching it with the uptake of the laundry. Free fluid is formed by the amount of water added to the washing machine minus the amount of water absorbed by the laundry. Cotton holds approximately 200% of its own we...
