Definitions

  • This invention relates to a flushing toilet bowl, and more particularly a seat sitting type flushing toilet bowl according to the preamble of the claim.
  • a flushing toilet bowl is known from US-A-1476445.
  • a further prior art seat sitting type flushing toilet is made such that an entire bowl surface (1') is formed by a curved surface having a large curvature. Due to this fact, a combined force of branch flows of flushing water injected from each of rim water discharging holes (4) of a rim water passage (5) is weak and so a flow of water stream may not be concentrated.
  • the prior art flushing toilet bowl may adjust the rim water discharging holes (4) to set a direction of each of branched flows to concentrate a force of the water streams.
  • means may generate a certain disturbance in a direction of each of the branched streams in response to a size and a position of each of the rim water discharging holes and so a desired object may not be attained.
  • This invention has been made in view of the above-mentioned problems and its object is to provide a flushing toilet bowl having less disturbance of a direction of flow of each of the flows and capable of concentrating a force of the water stream even if there are disturbances in sizes of the rim water discharging holes and their positions.
  • the flushing toilet bowl constructed as above is operated such that each of the branched flows of flushing water injected from the discharging holes is condensed at the recess part having the aforesaid V-shape and flown forcibly into a filth dropping recess of aforesaid V-shape without being dispersed.
  • the bowl (1) is provided with a rim water passage (5) communicating with the water supplying chamber (2) along an upper circumferencial end of the bowl (1) so as to project into the bowl (1).
  • the rim water passage (5) is provided with at its bottom surface some rim water discharging holes (4) with proper intervals.
  • the main body (A) of the toilet bowl is provided with a filth dropping recess (6) at the rearmost end of the bowl (1) and the rear surface of the filth dropping recess (6) is opened with an inlet (31) of the trap water discharging passage (3).
  • the above-mentioned structural form is of a well-known siphon type flushing toilet bowl and the present invention is made such that the bowl (1) in the siphon type flushing toilet bowl having the conventional type of well-known structural form has a bowl surface (1') at its rear bottom part formed into a substantial V-shape in its section.
  • the recess (a) of the substantial V-shaped section of the aforesaid bowl surface (1') is expandedly formed from a part near the central part of the bowl (1) to the part of the bowl rear wall (11) toward its rear portion encloses the filth dropping recess (6) and communicates with the recess (6) in its dropped form.
  • the recess (a) of the substantial V-shaped section concentrates each of branched streams of the washing water discharged from the rim water discharging holes (4) of the rim water passage (5) down the bowl surface (1') toward the part (a) and it can flow into the filth dropping recess (6) as one large stream.
  • a proper width part ranging from a part slightly above a part corresponding to a position of a water accumulating surface (b) to a part slightly lower than the former one except the rear wall side is formed as a curved surface having a lower curvature than that of each of the upper part and the lower part, thereby the corresponding part is formed as a stepped part (8) having such a shape as one slightly bulging outwardly.
