Apparatus for ultrasonic cleaning of carpet, upholstery, and similar materials
First Claim
1. Apparatus for cleaning carpet, upholstery, and similar materials, comprising a cleaning head adapted to rest on and be moved over material to be cleaned and having a central chamber, open at its bottom, and at least one relatively narrow chamber, open at its bottom, peripherally surrounding the central chamber;
- transducer means mounted in the central chamber for vibrating cleaning solution at an ultrasonic frequency;
means for supplying a cleaning solution to the central chamber in quantity sufficient to maintain a cleaning solution level in the chamber, when the cleaning head rests on the material to be cleaned, such that at least a portion of the transducer means is immersed in the cleaning solution, whereby vibration of the transducer means causes vibration of the solution; and
means for controlling pressure in the central chamber above the cleaning solution thereby controlling pressure of the cleaning solution in the central chamber and for controlling pressure in the at least one relatively narrow peripheral chamber surrounding the central chamber, to substantially eliminate any flow of air into the solution in the central chamber and to prevent escape of substantial amounts of solution from the cleaning head.

Abstract
A cleaning head is adapted to rest on and be moved over the material to be cleaned. The cleaning head has a central chamber, open at its bottom, and at least one relatively narrow chamber, open at its bottom, peripherally surrounding the central chamber. Ultrasonic transducer means are provided in the central chamber and means are provided for supplying a cleaning solution to the central chamber and for maintaining the level of the solution in the chamber such that at least a portion of the transducer means is immersed in the solution so that vibrations of the transducer means are imparted to the solution. Means are provided for adjusting, i.e. controlling, the pressure of the cleaning solution in the central chamber and the pressure in the at least one peripheral chamber to substantially eliminate the flow of air into the solution in the central chamber and to prevent escape of substantial amounts of solution from the cleaning head.
