Embodiment Construction

[0028] figure 1 A schematic view of the domestic appliance 100 is shown. The household appliance 100 is, for example, a washing machine with a water supply to a detergent container 133 comprising a plurality of chambers. Depending on the flow rate in the pressure line to the detergent container 133, the water is directed into one of the separate chambers located in the detergent container. Solenoid valves are used to control the flow rate in pressure lines. The solenoid valve is a valve actuated by an electromagnet. In the case of pilot controlled solenoid valves, the differential pressure of the operating pressure is used to open and close the valve. The drive of the pilot-controlled solenoid valve has a pilot control function by which the load on the main sealing element, for example a diaphragm or a piston, is relieved.

[0029] Figure 2A A cross-sectional view of the solenoid valve 101 and its components is shown in a closed state. The solenoid valve 101 comprises a...

Abstract

The invention relates to a household appliance comprising a solenoid valve (101) comprising a diaphragm (103) with a pilot hole (105) and a control pin (107) for closing said pilot hole (105) and spring means (109) for applying force to said control peg (107). The control pin (107) of the solenoid valve (101) comprises a pin (113) for protruding into the pilot hole (105).

Description

technical field [0001] The invention relates to a household appliance comprising a solenoid valve comprising a diaphragm. Background technique [0002] Solenoid valves with a diaphragm can be used in domestic appliances to switch on or off the flow in pressure lines. [0003] For example, publication EP685672A1 describes a washing machine having, for example, a solenoid valve for switching a water feeder, said valve comprising a diaphragm and a spring with a low spring constant. Although the flow of water can be turned on or off using such solenoid valves, fine-grained control of the flow rate is not possible. Contents of the invention [0004] It is an object of the present invention to provide a household appliance with a solenoid valve that can be used to control flow rate or pressure. [0005] Said object is achieved by a subject matter having the features according to the independent claims. Advantageous embodiment variants of the invention are the subject matter o...
