초록 ▼

A tub including a fluid system has a pump which includes a suction side and a pressure side; a nozzle for introducing a water-and-air mixture into the tub; the nozzle having a nozzle portion; a pressure line connecting the pressure side of the pump with the nozzle portion; a suction opening provided in a bottom region of the tub; and a suction line connecting the suction side of the pump with the suction opening. The fluid system further has a valve provided in the nozzle portion for cutting off fluid flow to the tub; an overflow line having a closable vent opening and being coupled to the suction side of the pump; a device for selectively allowing or blocking fluid communication between the overflow line and the suction line of the pump; and a supply source for introducing a cleaning agent at a location upstream of the nozzle as viewed in a direction of fluid flow therethrough.

대표청구항 ▼

An automatically closing nozzle for introducing a water-and-air mixture into a tub having a tub wall, comprising: (a) a valve body including a prechamber; (b) a support ring connected to said valve body for retaining said valve body against the tub wall; (c) a retaining ring which is releasably connected to said support ring and which is axially displaceable relative to said support ring; spring means for resiliently urging said retaining ring toward said prechamber; (e) a nozzle body having a generally tubular mouth and a ball-shaped portion which is spherically curved about a center of curvature, said nozzle body having a bore therein communicating with said prechamber and an annular sealing element bounding an inner perimeter portion of said bore; said nozzle body being pivotably retained in said valve body by said retaining ring; and (f) an air supply line having a mouth which protrudes into said bore in said nozzle body, said air supply line being disposed externally of the tub; said mouth having an outer surface portion having a generally spherical surface against which said annular sealing element of said nozzle body is urged by said spring means; whereby seating of said annular sealing element of said nozzle body against said generally spherical surface of said mouth substantially closes fluid communication between said prechamber and said generally tubular mouth of said nozzle body.
