ATTpRNEY United States Patent 3,166,773 SQNIC SURFACE CLEANER Floyd A. Wyczalek, Birnfingham, Mich, assignor to General Motors Corporation, Detroit, Mich, a corporation of Delaware Fiied Nov. 2, 1962, Ser. No. 234,939 5 Claims. (CI. 97)
This invention concerns a surface cleaner that utilizes vibratory energy for loosening and removing dirt, grease or any other foreign matter from a surface.
In a co-pending patent application of Wyczalek and Drayer, Serial Number 211,599, filed July 23, 1962, and assigned to the assignee of this invention, a surface cleaner device is shown having a plurality of elongated projections extending into a chamber which is adapted to be supplied with a liquid. A vibrator is connected to the device and provides a high-frequency rotating force vector that causes gyration of the projections so as to create liquid cavitation in an area proximate the surface being cleaned. The liquid cavitation results in a cleaning action that dis+ seminates and dislodges any foreign particles adhering to the surface.
This invention contemplates an improved surface cleaner of the above-described type which is simplified in construction and provides a more durable and efficient operating structure. More specifically, the apparatus made in accordance with this invention is'characterized in that it has a diaphragm mounted to a surface-engaging ring member in a manner such as to provide a cavity for receiving a cleaning liquid. A vibrator is coupled to the diaphragm and serves to drive the latter at a high frequency so as to cause liquid cavitation at the surface to be cleaned. For optimum results the vibrator is operated at a frequency at or above 100 cycles per second and at the resonant frequency of the apparatus.
A more complete understanding of the invention can be derived from the description taken in conjunction with the following drawings, in which:
FIG. 1 is a partially sectioned elevation view of a surface cleaner made in accordance with the invention, and
FIG. 2 is a plan view of the apparatus shown in FIG- URE 1.
Referring now to thedrawings, a surface cleaner constructed in accordance with the invention is shown comprising in general an annular base member or rim it) which is integrally formed with a diaphragm 12, which in turn supports an air-driven vibrator 14 at the center thereof. A handle 16 includes a pair of diverging arms which are fixed to the upper surface of the base member 10 and provides for manual movement of thelower surface along the surface to be cleaned during a cleaning operation. The entire surface cleaner is made from metal and in order to permit flexing action of the diaphragm an annular groove 18 is formed in the upper surface of the cleaner body directly above the inner'wall 19 of the rim; the groove serving to reduce the metal thickness at this point. The inner wall 19 and the lower surface 20, of the diaphragm define a cavity which, as shown in FIG. 2, is circular in form and is connected through a pasage 22 and-a conduit 24 to a source of cleaning liquid 26. A metering valve 28 is provided in the conduit 24 for controlling the rate of liquid supply to the cavity. In order to assure that the cavity is substantially filled with the liquid during the operation of the surface cleaner, a porous liquid-retainingpad 30 having a configuration conforming to that of the cavity can be provided in the latter. In this instance a sponge is used, however it should be understood that any other material having a liquid-retaining ability may be provided in the cavity. It has been found that the closer the lower surface of the diaphragm is positioned to the surface being cleaned, the less need there is 3,166,773 Patented Jan. 26, l95
poses, however, it will suffice to say that this vibrator includes a roller-type mass 32 freely housed within a working chamber 34 that has side walls defined by a pair of apertured discs 36 fixedly secured to the vibrator housing. Compressed air from a source 38 is metered to the vibrator through a control valve 40 and is directed into the working chamber 34 by a nozzle so positioned that the air stream emanating therefrom strikes the roller 32 at a tangential attitude so as to drive the latter in an orbiting manner about the working chamber. In this instance, the roller is driven in a plane perpendicular to the diaphragm 12 and accordingly provides a rotating force vector which also is perpendicular to the diaphragm.
It should be apparent that in operating the above-described surface cleaner, the lower surface 17 thereof is placed in contact with a flat surface to be cleaned. The valve 28 is then opened to direct cleaning liquid 26 to the pad 30 and thereafter valve dti is opened to supply pressurized air to the vibrator 14. For most efiicient operation the vibrator is operated at a frequency equal to the resonant frequency of the apparatus resulting in vibratory energy being transmitted to the liquid and creating a multiplicity of liquid cavitating bubbles at the surface being cleaned. Each of the cavitating bubbles contains a vacuum of such magnitude that when it collapses on a central nucleus, an enormous force is developed which acts on the surface and accounts for the dissemination and dislodging of any foreign particles adhering to the surface. As is well known, cavitation is produced when vibratory energy is supplied to a liquid medium and a liquid particle is moved away from an adjacent liquid paritcle so as to cause a vacuolar surface to exist between thetwo adjacent particles. This effect can be produced by motion of particles in two opposite directions, or by motion of particles in the same direction so long as one particle has a greater velocity thanthe other.
It has been found that for successful operation of a surface cleaner of the above-described type, the diaphragm should be made thin enough in order to resonate at the the cavity. To those skilled in the art this, of course,
should be apparent. Nevertheless, it should be noted that in operating this apparatus, for optimum results the vibrator should be operated above cycles per second and at the resonant frequency of the assembly.
Finally, it should be noted that as in the case of the aforementioned patent application, the diameter of the roller in the vibrator is more than one-half the diameter of the confining or working chamber. It is important to Various changes and modifications can be made in the above-described device without departing from the spirit of the invention. It should be understood that such changes and modifications are contemplated by the inventor and he does not intend to be limited except by the scope of the appended claims.
