TOILET DEVICE Russian patent published in 2020 - IPC E03D11/02 E03F1/00 

FIELD: sanitary equipment.

SUBSTANCE: toilet device contains bowl of gravitational toilet provided with siphon and outlet having diameter corresponding to specified first diameter of gravity sewer. Device further includes a flush water tank, connected to water source by means of water valve and with gravity toilet bowl by means of flushing valve for flushing water supply to bowl of gravitational toilet during washing sequence, and triggering means for triggering flushing sequence of gravity toilet bowl. Device further includes a drain valve, a vacuum sewer pipeline with a given second diameter and a control mechanism, made with possibility of activation by means of launching facility and connected to pipeline of vacuum sewer, drain valve, water valve and flushing valve, as well as a vacuum plant connected to the vacuum sewer pipeline to form a vacuum in the vacuum sewer pipeline. Toilet device contains an adapter to provide connection along the flow between the outlet, with the specified first diameter of the gravity sewer pipe, and a drain valve with the specified second diameter of the vacuum sewerage pipeline. First end of the drain valve is directly connected by means of an adapter to the bowl outlet of the gravitational toilet. Drain valve second end opposite to said first end is directly connected to vacuum sewer pipeline, whereby the impurities located in the bowl of the gravitational toilet can be directly drained from the gravity toilet bowl through the siphon and the outlet provided with the adapter, into vacuum sewer pipeline via drain valve during washing sequence.

EFFECT: enabling the development of a flexible device which additionally provides freedom of choice with respect to the toilet bowl.
