Abstract (en)

The water supply unit (1) comprises at least a water connection (A) and a water preparation unit (1) with safety switch (1b) which switches off the cleaning apparatus when the pressure raising device (4) is no longer supplied with sufficient water. The safety switch can be a floating switch triggered when a certain water level is not reached. An overflow switch can be provided to stop the water supply when the required water level is reached.

Abstract (de)

Bei einem Reinigungsgerät für die Reinigung von Oberflächen mit einem Druckbehälter (2) zur Aufnahme von Wasser und Festteilen und Speicherung dieser unter Druck, weisen Schalteinrichtungen (21-24) unterschiedliche Schaltzustände auf, bei denen entsprechend Druckluft und/oder Wasser und/oder Gemisch an der Sprühvorrichtung (27) ausgegeben werden, wobei das Gemisch durch eine Auslaßöffnung des Druckbehälters (2) über die Auslaß-Leitung (2e) und die Gemisch-Schaltvorrichtung (23) zur Sprühvorrichtung (27) ausgegeben wird, während gleichzeitig über die Wassereinspritzleitung (12) und eine Wassereinspritzvorrichtung (21) Wasser von der Druckerhöhungseinrichtung (4) in den Druckbehälter (2) zugeführt wird. Ferner umfaßt die Wasserversorgungseinrichtung (1) zumindest einen Wasseranschluß (A) und eine Wasserbereitstellungseinheit mit einem Sicherheitsschalter, wobei der Sicherheitsschalter das Reinigungsgerät abschaltet, wenn die Druckerhöhungseinrichtung (4) durch die Wasserversorgungseinrichtung (1) nicht mehr ausreichend mit Wasser versorgt wird. <IMAGE>
