TOILET AND METHOD FOR WASHING OF ITS BOWL INTERNAL SURFACE Russian patent published in 2010 - IPC B61D35/00 E03D11/08 

FIELD: personal demand items.

SUBSTANCE: device comprises nozzles (1), which are installed under upper edge of toilet bowl (2). Each nozzle (1) comprises head arranged in the form of disk with outlet slot for attachment to internal surface of bowl (2), and extended part for attachment of nozzle (1) to pipe that supplies washing liquid. Extended part is provided with internal channel that communicates to outlet slot. Side walls of outlet slot create angle ε in between, which makes 40°-85°. Between nozzle and internal surface of bowl, and also between external surface of bowl and nut there might be washers installed from additional set of washers of various thickness, flat or wedge-like shape, for instance, from elastic polymer material, for correction of nozzles (1) position versus bowl (2). During adjustment of flushing system, flat jets of washing liquid are supplied under pressure so that their axes are inclined towards horizon at the angle α, which makes 10-30°, and plane of each jet symmetry creates angle β with value from 5 to 15° with plane, which is tangential to internal surface of bowl in point of this bowl surface crossing with axis of this jet symmetry.

EFFECT: invention improves quality of flushing with saving of washing liquid.
