Claims
- 1. An apparatus for producing foam for cleaning of textiles, especially of rugs and carpets, comprising applying means for applying foam to a surface to be cleaned; wall means defining two chambers each of which is adapted to accommodate one of two chemical components which react upon contact with one another and spontaneously produce foam for cleaning purposes; first and second passage means connecting said chambers with one another and with said applying means; and control means for selectively varying the effective cross-section of said first passage means so as to permit contacting of controlled amounts of one of said components with the other component via said first passage means, to result in spontaneous production of foam which is supplied to said applying means.
- 2. An apparatus as defined in claim 1, wherein one of said chambers is adapted to accommodate one of said chemical components in form of an aqueous solution; and wherein said one chamber is located upwardly of the other of said chambers to permit gravity flow of said solution from said one chamber into said other chamber.
- 3. An apparatus as defined in claim 2, said one chamber having an upper inlet end for water; and further comprising a sieve in said one chamber in the region of said upper inlet end.
- 4. An apparatus as defined in claim 1, wherein one of said chambers is provided with a plurality of apertured partition walls.
- 5. An apparatus as defined in claim 4, wherein said partition walls have a substantially vertical orientation.
- 6. An apparatus as defined in claim 4, wherein said partition walls have a substantially horizontal orientation.
- 7. An apparatus as defined in claim 1, one of said chambers having an upper region spaced from said applying means and formed with a plurality of slot-shaped openings for exiting of the spontaneously produced foam from said one chamber.
- 8. An apparatus as defined in claim 1, one of said chambers having an upper region provided with a partition wall which forms a foam collecting channel.
- 9. An apparatus as defined in claim 8, wherein said one chamber is of substantially triangular cross section, and wherein said foam collecting channel is substantially horizontally oriented when said apparatus is in operating position.
- 10. An apparatus as defined in claim 1, wherein one of said chambers is formed by an elastically deformable container having an upper outlet, and wherein the other of said chambers is formed by a hollow cap member mounted on said container and having a foam-dispensing outlet and an interior which accommodates one of said components and communicates with said outlet; and further comprising a riser tube in said container and communicating with said outlet so that contents of said container exit through said outlet and into said interior of said cap member in response to elastic deformation of said container.
- 11. An apparatus as defined in claim 10, wherein said container is a plastic squeeze bottle.
- 12. An apparatus as defined in claim 10; and further comprising a foam-permeable wall extending across said foam-dispensing outlet.
