EJECTOR TOILET Russian patent published in 2024 - IPC B61D35/00 E03D5/00 E03D11/02 

FIELD: sewage systems.

SUBSTANCE: invention relates to water-saving toilets, specifically to ejector toilets. Ejector toilet contains bowl 1. On the lower side bowl 1 cavity is connected to toilet effluent outlet pipe 3 via hydraulic lock 2 and ejector pump (EP) 11. EP 11 comprises water pressure ejector 12, suction 13 and drain 14 branch pipes. Water-pressure ejector 13 is made in the form of turbine nozzle 12 installed in the plugged end of EP 11 coaxially with cavity of its drain branch pipe and cavity of outlet pipe 3. At that, suction branch pipe 13 of EP 11 is connected to outlet of hydraulic lock 2 and is installed orthogonal to cavity of drain branch pipe 14 of EP 11. Turbo injector 12 of EP 11 by feed water is connected through high pressure pump (HPP) 10 to first water outlet three-way splitter 15. Second water outlet of splitter 15 is connected through pipeline 5 to washing nozzles 4 installed in the upper part of the cavity of bowl 1. Water supply input of three-way splitter 15 is connected via electromagnetic valve (EMV) 6 with quick-release coupling 7 for connection to external water supply source. EMV 6 and HPP 10 are made with digital control and are connected by control signals to corresponding outputs of control unit (CU) 8. CU 8 is made in the form of a controller on programmable logic devices (PLD), equipped with a corresponding program for controlling a toilet bowl and button 9 for switching on said program. CU 8 control program is selected based on the condition of economical water consumption to ensure high-quality cleaning of toilet bowl 1 and effective drainage of toilet effluents into external sewage system.

EFFECT: decreasing feed water flow rate.
