Abstract: A laundry washing machine comprising: a cabinet; a tub inside the cabinet and comprising a first and second shells fixed together and defining a sump at a bottom region of the tub; a rotatable drum in the tub; a draining circuit fluidly connected to the sump for draining liquid from the bottom of the latter; a level detection device configured for detecting the level of liquid within the tub and comprising an air chamber having a liquid inlet provided at the sump and in fluid communication with the internal of the latter; and a recirculation circuit configured for withdrawing liquid from the tub and to re-admit such a liquid into the tub through an outlet opening positioned in the sump. The outlet opening of the recirculation circuit and the liquid inlet of the level detection device are located one on the first shell and the other on second shell.

Abstract: A washing drum configured to be rotatably mounted in a laundry washing machine wherein laundry to be washed may be placed. The washing drum has a tubular body wall configured to rotate around a rotational axis, and the tubular body wall comprises at least one bulge protruding from the tubular body wall towards the rotational axis. The contour of the bulge at the tubular body wall has the shape of a squircle, wherein the reference axis of the squircle-shaped contour is inclined with respect to the rotational axis.

Abstract: A laundry washing machine (1) has a washing tub (3) external to a rotatable washing drum (4) adapted to receive laundry. The machine further has a level sensing device (19) having a pressure sensor (50) suitable for determining the liquid level inside the washing tub (3). The level sensing device (19) further has an air chamber (51; 151) connectable to a detection outlet (60) associated to the washing tub (3). A liquid flowing path (61) is defined between the detection outlet (60) and the air chamber (51; 151), wherein the liquid may flow between the washing tub (3) and the air chamber (51;151). In a mounted configuration, the air chamber (51; 151) is associated to the washing tub (3) and the laundry washing machine (1) is positioned in its working position, and the path (61) is shaped such that at least a section of the path, in a plane perpendicular to a flowing direction (V) of the liquid, has the upper part comprising a rectilinear portion (64a; 64b; 164a).

Abstract: A laundry machine for treating laundry is provided with a tub which includes a discharge hole for draining liquid out of the tub, and a plurality of drain-connection elements. The laundry machine further includes a discharge duct fluidly connected to the discharge hole for collecting liquid drained from the tub, and fixed to the tub by at least one of the drain-connection elements. The plurality of drain-connection elements include at least two different types of drain-connection elements, each one adapted for fixing a corresponding type of discharge duct to the tub by means of a corresponding connection arrangement.

Abstract: A washing group (1) for laundry washing machines has a hollow washing tub (2), a revolving drum (3) fitted in axially rotatable manner inside the washing tub (2), and a motor assembly (4) which is rigidly attached outside the washing tub (2) and is capable of driving into rotation the revolving drum (3) inside the washing tub (2). The motor assembly (4) has a drive motor (8) and a supporting structure (10) provided with a number of connecting arms (15) each of which juts out from the drive motor (8) towards the peripheral wall (9) of washing tub (2), and has the distal end fitted onto a corresponding coupling pin (14) which cantilevered extends from the washing tub (2). Each coupling pin (14) is substantially ogival-shaped and the distal end of each connecting arm (15) having a substantially ogival-shaped, hollow seat (16) which is substantially complementary in shape to that of the corresponding coupling pin (14) so as to be axially engaged by said coupling pin (14).

Abstract: Present invention relates to a laundry machine (100) for treating laundry provided with a tub (200) which comprises a discharge hole (240) for draining liquid out of the tub (200), and a plurality of drain-connection elements (245a, 250a, 250b, 250c, 250d). The laundry machine (100) further comprises a discharge duct (300; 500; 600) fluidly connected to the discharge hole (240) for collecting liquid drained from the tub (200), and fixed to the tub by at least one of the drain-connection elements. The plurality of drain-connection elements (245a, 250a, 250b, 250c, 250d) comprises at least two different types of drain-connection elements (245a, 250a, 250b, 250c, 250d), each one adapted for fixing a corresponding type of discharge duct to the tub (200) by means of a corresponding connection arrangement.
