A device for detecting the liquid level in a tank of an electric household appliance includes an airtight bell connected on one side to the tank and on the opposite side to a pressure switch by means of a hose-carrier nipple. As the water level of the tank increases, the pressure of the air trapped in the bell increases, which is detected by the pressure switch. The airtight bell is defined by a rectilinear tube which obliquely protrudes from underneath the tank and externally to the same, towards a front panel of a casing of the household appliance for convenient access and easy cleaning. A shielding means within the tank is arranged in front the rectilinear tube to create a siphon between the bell and the tank and to prevent the water level in the tube from dropping past a minimum point.
