VACUUM TOILET SINK Russian patent published in 2013 - IPC E03D11/00 E03D5/00 B61D35/00 

FIELD: construction.

SUBSTANCE: vacuum toilet sink includes facilities for washing of the inner surface of a cup 1 and facilities for removal of wastes from it. Facilities for washing of the inner surface of the cup 1 are made in the form of water nozzles 2. Water nozzles are connected with a common header 3. A pipeline 4 of water supply is connected to the header. The pipeline has a water valve 5 with an electric drive 6. Facilities for wastes removal from the cup are made in the form of a drainage valve 7. The drainage valve is installed on the outlet hole of the cup 1. The drainage valve has a hollow body 9, an elastic collar 10 and a mechanism 11 of collar clamping. The collar is arranged in the cavity of the body and is attached to the side walls of the body. The cavity of the drainage valve 7 body communicates with a three-way valve 12 equipped with an electric drive 13. The three-way valve may connect the drainage valve body cavity either with atmosphere or with a pipeline 14. The pipeline 14 diverts from the drainage vacuum manifold. The toilet sink equipment comprises a liquid level sensor 15, a button 16 to start washing of the cup 1, a lamp 17 to indicate toilet sink operation mode, a pressure sensor 18 and a control unit 19. The liquid level sensor 15 is installed in the upper part of the cup 1. The pressure sensor is arranged in the drainage vacuum manifold. The control unit is connected with electric drives of the three-way valve 12 and the water valve 5, with the pressure sensor 18 in the drainage vacuum manifold, with the liquid level sensor 15 in the cup 1, with the button 16 to start washing of the cup 1 and with the lamp 17 of operation mode indication. The control unit 19 includes an inbuilt controller. The controller provides for correction of time setpoints of duration of the cup 1 washing operation, duration of the operation of wastes removal from the cup and duration of the pause between the start of the operation of cup washing and start of the operation of wastes removal from the cup.

EFFECT: increased reliability of a device with saving of water consumption used to wash a toilet sink cup.
