Embodiment Construction

[0055] figure 1 is a schematic view of a part of a washing machine in which the described method relevant for explanation is implemented. Such as figure 1 The washing machine of the illustrated exemplary embodiment is provided with an outer tub 1 in which a drum 2 is rotatably mounted and can be driven by means of a drive motor 14 . With respect to ergonomics when using such a washing machine, the axis of rotation 3 of the drum 2 is inclined upwards and forwards at a small angle (eg 13°) from horizontal to provide easier access and viewing of the interior of the drum 2 . By this structure in combination with a specially formed laundry agitator 4 for washing liquid 6 on the inner surface of the drum shell and a supply means 5, an enhanced flow of laundry 7 for washing liquid and soap and a reduction in free washing liquid is also achieved .

[0056] The soap formed during the laundry method using soap should especially fill the space between the drum 2 and the tub 1 .

Abstract

The invention relates to a method for controlling the generation of suds during the treatment of washing with suds consisting of an aqueous surfactant solution in a programme-controlled washing machine. Said machine comprises a solution drain system that is situated on the base of an outer tub (1), a solution pump, a rotating drum (2) and a heating unit (13). The method comprises the following steps: a) detecting the suds contained in the outer tub (1) and / or in the drum (2); and b) setting and / or maintaining a predefined range for the concentration of the suds between c1 and c2, the detection (a) of the suds being carried out by means of one or several sensors (15), which track a hydrostatic pressure p, a temporal gradient (Delta p / Delta t) of the hydrostatic pressure p and / or a conductance k in the outer tub (1) and / or in the drum (2). A measured hydrostatic pressure p is compared to a predetermined lower value p1 for the hydrostatic pressure and a predetermined upper value p2 for the hydrostatic pressure and if pp2, the speed U of the drum (2) is decreased. The invention also relates to a washing machine that is suitable for carrying out said method.

Description

technical field [0001] The present invention relates to a method of controlling the production of soap in a program-controlled washing machine, in particular during the treatment of laundry with soap, and also to a washing machine which is particularly suitable for carrying out the method. Background technique [0002] Using known methods, the laundry to be washed is simply mixed with an amount of water or washing liquid, also known as "washing liquor", which is sufficient to saturate the laundry to be washed with water and to render substantially 2 A minimum of free wash liquid of up to 3 liters enables material interchange between the heater for heating the wash liquid and the laundry. Free wash corresponds to the residue of the washing liquid that is not contained by the laundry and thus appears as a liquid. The corresponding size of the amount of water in the wash liquor is ensured by means for adjusting the water level in the drum and adapting the amount of water to th...
