Liquid level indicator in household water appliance - is installed in e.g. dishwasher and consists of water filled compartment and air chamber

摘要

The liq. level indicator is designed for use in a domestic appliance, such as a dish-washer, which is filled with water with the aid of water flow controlled by a valve. It uses a compartment (1) which fills with water when a certain level is reached. The air in an air chamber (3) is compressed. A solenoid valve (10) has two through-flow ducts, one of which joins the outlet, and the other joins the inflow water pipe to the machine.
