VACUUM TOILET SYSTEM Russian patent published in 2020 - IPC E03D9/00 B60R15/04 B61D35/00 

FIELD: sanitation equipment.

SUBSTANCE: invention relates to sanitary equipment. Vacuum toilet system contains at least one toilet bowl (14) equipped with nozzles (12) of toilet bowl washing, connected to the toilet washing device (1) output, accumulating tank (28) under atmospheric pressure and device (3) for creation of high pressure, including high pressure receiver (4), compressor (5) and pressure relay (6). Outlet of toilet bowl (14) is connected via liquid gate (15) to the inlet of check valve (16) of toilet bowl, the outlet of which is connected via pipeline (17) to the inlet of drains of intermediate tank (18). Simultaneously, the toilet bowl washing device (1) operation control input is connected to the draining control button (2) outlet, and is also connected to the vacuum supply control (11) input input, output of which is connected to control input of electromagnetic valve (13) of vacuum supply, which input is connected through vacuum supply pipeline (8) with vacuum receiver (20) output, and output is connected to vacuum inlet of intermediate tank (18). Outlet of drain control button (2) is connected to input of high pressure supply control timer (9), output of which is connected to control input of high pressure supply electromagnetic valve (10), which input through high pressure supply pipeline (7) is connected to high pressure receiver (4) output, and output is connected to intermediate tank (18) high pressure input, outlet of which, through series-connected check valve (26) and discharge pipeline (27), is connected to storage tank (28) at atmospheric pressure. Input of vacuum receiver (20) is connected to output of vacuum pump (21), control input of which is connected through volumetric vacuum meter (22) to vacuum receiver (20) control output. Control input of vacuum pump (21) is connected to red warning light (23) and through inverting device (25) is connected to green warning light (24).

EFFECT: simplified design with improved consumer properties, higher reliability.
