Abstract: The invention relates to combined water supply and sewerage installations, and particularly to equipment of self-cleaning sanitary cubicles. This equipment can be used for arrangement of sanitary cubicles in permanent facilities and in quickly erected temporary facilities, in separately installed modules. The technical result consists in simplifying the design and manufacturing technology of parts and assemblies, increasing vandal resistance due to hard floor design. The use of a more rational floor cleaning device connected to a separate drive reduced the time and amount of washing liquid required for cleaning, and increased the efficiency of sanitation, which, in turn, contributed to an increase in the throughput of the sanitary cubicle. Combination of simple technical solutions used in the equipment design contributed to achievement of such objectives as cheaper and simpler operation, lowering the human factor in cleanliness maintenance, automation of operation and reliability of sanitary cubicle cleanliness maintenance in the automatic mode with minimal use of manual labor in jobs uncomfortable for people. The sanitary cubicle comprises a hard floor made of metal, plastic and/or other hard wear-resistant materials, a wall-mounted toilet bowl, walls, one of which has a hole at the floor level for sweeping garbage into the garbage container, and the entrance door located in the opening of the other wall. The sanitary cubicle has enclosing elements adjacent to the floor and to all walls, except for the wall with said opening; two of the enclosing elements adjacent to the opposite walls have longitudinal slots, and a floor cleaning device comprising nozzles connected to pipelines for supplying washing liquid to the floor surface; a tool of the floor cleaning device in the form of an elongated washing element including a brush and/or a scraper made of a resilient-elastic material connected to a drive and capable of reciprocating movement parallel to the floor, the opposite ends of the tool are connected to holders located in the longitudinal slots made in the enclosing elements adjacent to the opposite walls; the enclosing element located opposite the wall with the opening is provided with an aperture for placement of the tool in the non-working position in the niche formed behind the aperture, and the longitudinal slots may have seals of resilient-elastic materials. The tool drive of the floor cleaning device can be made in the form of a gear motor connected to a screw-nut pair, located in the guide in the form of channel bar, the screw is fixed at its ends in two bearing units, and a rod with a carriage at each end is attached to the nut, each carriage is connected to the end of holder located in the slot and is in contact with one of two parallel guides mounted on fixed elements of the sanitary cubicle such as the floor frame and/or walls. The screw-nut pair, the rod, two carriages and two guides are located under the hard floor. Nozzles for supplying washing liquid to the floor surface are built into one and/or several enclosing elements, and the waste bin is located outside the floor. To control actuators of the floor cleaning device such as the tool drive, the actuator of the valve on the washing liquid supply pipelines, an automation unit is used.
