Multiple-addition valve for a system for metering liquid or paste-like auxiliary washing agents

摘要

A system for automatically metering liquid or paste-like auxiliary washing agents stored in reservoirs for automatically controlled washing machines. It has a central fluid line disposed in a housing bottom and a plurality of nozzles disposed in the housing bottom on a circular line extending concentrically to the axis of a rotor. The nozzles can be connected individually to the outlet by a connecting line inside the motor-drivable rotor. In the connection to the connecting line, seals are provided. Due to a force continually axially acting on the rotor in the direction of the housing bottom, said rotor presses the seals until the contact surfaces of the rotor and the housing bottom substantially form a common plane.

主权项

1. A washing machine comprising:
a multiple-addition valve that includes:
a housing bottom with a central fluid line;a rotor having a connecting line, the connecting line having an outlet in communication with the central fluid line and an inlet, the rotor being positioned adjacent to the housing bottom, and the rotor being rotatable relative to the housing bottom;a plurality of nozzles positioned opposite the rotor on the housing bottom and concentrically about a central axis of the rotor, each of the plurality of nozzles being individually connectable to the central fluid line via the connecting line; a first seal structured to form a fluid seal with the outlet of the connecting line and the central fluid line; a plurality of additional seals, each of the plurality of additional seals structured to form a fluid seal with the inlet of the connecting line and a corresponding one of the plurality of nozzles; and a plurality of reservoirs, each of the plurality of reservoirs connected to a corresponding one of the plurality of nozzles, wherein the central fluid line is connected to a dispensing device via a pump, wherein the first seal and the plurality of additional seals are fixed on the housing bottom during rotation of the rotor, wherein one of the plurality of nozzles is configured to supply water and is not associated with one of the plurality of additional seals, and wherein the rotor is positioned against the housing bottom at a defined minimum distance such that the first seal and the plurality of additional seals are compressed by contact between a rotor surface and a housing bottom surface when the rotor is rotated relative to the housing bottom.
