Patent ID: 10358763

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).
