| 摘要 |
The invention is directed to improvements in foam type carpet cleaners and, more particularily, to the production of a relatively dry water-detergent mixture foam which is producted by applying drops of the mixture into an airstream duct in which is located a rotating propeller, or fan blade, driven by the airstream, the propeller contacting the drops and producing a fine droplet dispersion of the mixture, which dispersion is blown, by the same air stream, through a fine mesh screen to produce a foam which is applied, to a carpet to be cleaned, by a foam spreader. The foam is then brushed through the nap of a carpet by a rotating brush associated with the spreader. A debris collector is preferably associated with the brush to pick up carpet debris and spent foam.
