DEVICE FOR CLEANING OF ENCLOSED SPACES

摘要

The invention relates to a device for cleaning of enclosed spaces by means of liquid sprayed out. The device comprises a housing (1) with a stationary part (2) to which the liquid is supplied and on which a rotatable part (3) bearing a hub (5) is mounted. The hub (5) is provided with at least one spray nozzle (4). The hub (5) is suspended in a bearing (7) in the rotatable part (3) via an element (6). The rotatable part (3) comprises a turbine (8) driven by the liquid and having a planetary gear (9) for turning the rotatable part (3) and at least one nozzle (4) in such a way that the liquid sprayed out by at least one of the nozzles (4) during rotation sweeps across the inside of the enclosed spaces. The stationary part (2) comprises an upper ring gear (10) which is in engagement with a lower ring gear (11) on the hub (5), which two ring gears (10, 11) are surrounded by the housing (1). The turbine (8) and the planetary gear (9) are fitted in the rotatable part (3) in order to achieve a compact device.
