FIELD: sanitation equipment.

SUBSTANCE: group of inventions relates to sanitary equipment. Flushing device is placed in at least one seat on the toilet bowl and can be used both in the bidet-containing toilet bowls and in the bowels not containing the bidet system. Device comprises at least one outer body mounted on a toilet bowl, at least one inner body mounted inside the outer body, at least one completely open side channel and at least one partially open and partially closed side channel, arranged on the inner body, respectively, on the right and left sides relative to the center of the inner body, at least one middle channel arranged in the middle section in the same direction as the center of the inner body, and at least one cover arranged on the inner body. Concerning said channels, partially open and partially closed side channel is open for water flow in one part and closed for water flow in its other part, in other words, it comprises both an open part of the side channel and a closed part of the side channel. Open part of the side channel, in which the water flow takes place, has diameter smaller than the diameter of the other completely open side channel, which is completely open for water flow. Open part of side channel of said partially open and partially closed side channel, which is open for water flow, has cross-section area in range of 80–100 mm², and the other, fully open channel, which is completely open for water flow, has a cross-sectional area in range of 240–300 mm². Method of flushing toilet bowl using above described device consists in the fact that the toilet is flushed by stages, at which water reaching the flushing device through the channel for pure water, moves along side edges of the toilet bowl through the completely open side channel and partially open and partially closed side channel, and water jets advancing along two side edges are connected at point near completely open side channel having large diameter, in other words, they are connected on a side edge in a section with a completely open side channel at a point forming with a fusion line drawn from the clean water channel to the center of the toilet bowl, an angle with any value in range of 60–120°, and then they are merged into a toilet bowl.
