Definitions

• the present invention refers to a washing machine, particularly to a front-loading washing machine, comprising a washing tub and a washing drum rotatably mounted inside said tub, a water filter and at least one sensor for detecting a water level in the washing machine and/ or a degree of water clarity and/or similar washing parameters.
• a sensor in a washing machine is intended to sense at least one physical parameter in the washing machine.
• the washing water gets dirty and the sensor detects the level of dirtiness of the washing water and, thus, as a result affects the programmed washing parameters.
• Known washing machines comprise sensors which are located either on a washing tub, a heater or a filter body. The result of said arrangement of the sensor je relatively low sensing precision of the sensor. In addition, installation of the sensor is rather difficult resulting in a costly product.
• Fig. 1 a three-dimensional view of a washing machine with a removed side
• Fig. 2 a three-dimensional view of a detail II of Fig. 1.
• FIG. 1 shows a view of a washing machine comprising a body with a front wall 1 in which a loading aperture 2 for loading the washing machine with laundry to be washed is provided, wherein said aperture 2 can be closed by a door 3.
• a cylindrical washing tub 4 elastically supported in the washing machine.
• a washing drum (not shown in the Fig.) for accommodating laundry to be washed.
• a wahing water filter is mounted in a filter body 5, said filter being closed by a cover 6 in said front wall 1.
• Said washing tub 4 and said filter body 5 of the washing water filter are fluidly coupled by means of a connecting line 7.
• Said connecting line 7 is provided at a first end thereof with a first flange 8 configured to be connected to said washing tub 4.
• a second end of the connecting line 7 is provided with a second flange 9 configured to be connected to said filter body 5.
• the connecting line 7 comprises a receiving section 10 that is downstream attached directly to the first flange 8.
• an equalising section 11 is attached to said receiving section 10 configured to equalise geometric irregularities of the connection of the washing tub 4 with the filter body 5, and to prevent vibrations to be transferred from the washing tub 4.
• said equalising section 11 is selected as a flexible bellow like tubular section.
• an end section 12 is downstream attached to the equalising section 11, the free end of said end section 12 being attached to said second flange 9.
• said end section 12 can comprise a reducing section for connecting to the second flange 9.
• At least said receiving section 10 is formed with at least one tubular extension 13 extending approximately perpendicular to a periphery of the receiving section 10 and being fluidly coupled therewith.
• Said tubular extension 13 is configured to accommodate at least one sensor 14 by means of which is detected at least one physical parameter such as a pressure, temperature, acceleration, turbidity and/or colouration of the washing fluid and similar.
• said tubular extension 13 can be intended for other purposes.
• the tubular extension 13 can be used as a place for injecting air, as an UV lamp carrier and similar.
• At least said end section 12 is formed with at least one tubular extension 15 extending approximately perpendicular to the periphery of the end section 12 and is fluidly coupled therewith.
• Said tubular extension 15 is configured to accommodate at least one additional sensor (not shown in the Fig.) by means of which at least one physical parameter such as a pressure, temperature, acceleration, turbidity and/or colouration of the washing fluid and similar is detected.
• said tubular extension 15 can be intended for other purposes.
• the tubular extension 15 can be used as a place for injecting air, as UV lamp carrier and similar.
• Said sensor 14 and/or said additional sensor is/are inserted in the tubular extension 13, 15 with an interference fit so that any leakage of the washing water is prevented.
• the requirement for additional fixing elements for fixing sensors becomes superfluous.
• both said sensor 14 and said additional sensor can be selected as a digital and/or analogue sensors.
