Definitions

  • the invention relates to a method and a device for using a seat toilet, urinals or the like, in which foam is generated before the excrement is deposited in the bowl.
  • DE-C-20 23 133 discloses a method for odorless depositing of excrement in a toilet bowl provided with a water rinse of the usual type, in which, prior to depositing the excrement, a foam-forming preparation in tablet form or in an aerosol can is placed in the toilet bowl a foam pillow is generated, which when you press the water flush together with the excrement is removed.
  • This procedure has never been put into practice. The reason for this is in all likelihood that a foam pillow can be produced using tablets or an aerosol can, which at most serves as an odor barrier for 5 minutes until rinsing and which has to be produced in a relatively complex manner, ie by separate manipulation of the user.

If, on the other hand, the construction of the toilet is such that the water volume is only partially exchanged, it is advantageous to spray or otherwise apply a foam dissolver, possibly only water, onto the introduced foam before triggering the rinsing process collapses.

Abstract

Selon un procédé d'utilisation de sièges de toilettes, urinoirs ou similaires, une mousse se forme à l'intérieur de la cuvette avant que des excréments n'y soient déposés. Pour former ce tapis de mousse, un agent moussant est ajouté à l'eau de rinçage de sorte que la mousse se formant en même temps que l'agent moussant arrive dans la cuvette avec l'eau de rinçage. L'agent moussant est introduit dans le conduit de chasse d'eau (17) au moyen d'un robinet de chasse d'eau (10) agencé dans le conduit de chasse d'eau (17) juste au-dessous de l'orifice d'admission d'air (18) associé au robinet de chasse d'eau (10), notamment juste avant la fin de la chasse d'eau, c'est-à-dire, juste avant que le robinet de chasse d'eau (10) ne revienne à sa position de fermeture.
