DEVICE FOR DETECTING THE LIQUID LEVEL IN THE WASHING BATH OF A WASHING MACHINE

摘要

The device (1) comprises a body (2) in which are formed a first and second chamber (14, 15) separated sealingly from each other by a resilient diaphragm (6). The first chamber (14) has an inlet opening (2c) intended to be put in pneumatic communication with the region of a container which is above the liquid; the second chamber (15) communicates with the atmosphere. A winding (8) is mounted in a fixed position in the body (2), on the side opposite the first chamber (14) with respect to the diaphragm (6). A core (11) is coupled to the diaphragm (6) and is movable with respect to the winding (8) such that in operation the inductance of the winding (8) varies as a function of the position of the core. The device also comprises a first spring (12) tending to move the core (11) towards the diaphragm (6), and a second spring (16) tending to oppose the action of the first spring (12). The second spring (16) is positioned in the second chamber (15).
