Abstract
Abstract An apparatus for physically cleaning objects by using ultrasonic waves which employs a unique arrangement of a cleaning liquid tub and a plurality of ultrasonic wave oscillators. The arrangement is such that the cleaning tub comprises two oppositely inclined bottom walls in generally V-shaped cross-section, and the ultrasonic wave oscillators are installed on one of the inclined bottom walls of the cleaning liquid tub having a relatively smaller area than the conventional flat bottom construction. By virtue of this arrangement, the ultrasonic waves can be radiated much more effectively leaving less dead space than in the conventional construction, thus resulting in such advantageous features as remarkable improvement of the radiation effects of ultrasonic waves on the object to be cleaned and effective reduction of the number of ultrasonic wave oscillators without sacrificing the ultrasonic wave cleaning effect.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
123 words
In an ultrasonic wave cleaning apparatus including an opentop cleaning liquid tub having a bottom of V-shaped cross section, including a pair of first and second oppositely inclined bottom walls, and ultrasonic wave oscillating means on said first bottom wall to radiate ultrasonic waves into a cleaning liquid contained in said tub: an improvement wherein said second bottom wall is less inclined with respect to the horizontal than said first bottom wall so as to extend obliquely upwardly over a greater length than said first bottom wall, said ultrasonic wave oscillating means being oriented to radiate the ultrasonic waves obliquely upwardly along and parallel to said second bottom wall, said tub being fully open upwardly at the upper edge of the bottom walls.
Claim 2
Dependent Claim
123 words
In an ultrasonic wave cleaning apparatus including an opentop cleaning liquid tub having a bottom of V-shaped cross section, including a pair of first and second oppositely inclined bottom walls, and ultrasonic wave oscillating means on said first bottom wall to radiate ultrasonic waves into a cleaning liquid contained in said tub: an improvement wherein said second bottom wall is less inclined with respect to the horizontal than said first bottom wall so as to extend obliquely upwardly over a greater length than said first bottom wall, said ultrasonic wave oscillating means being oriented to radiate the ultrasonic waves obliquely upwardly along and parallel to said second bottom wall, said tub being fully open upwardly at the upper edge of the bottom walls.
Claim 3
Dependent Claim
23 words
An ultrasonic wave cleaning apparatus as claimed in claim 1, further comprising means for injecting said cleaning liquid into said cleaning liquid tub.
Claim 4
Dependent Claim
32 words
An ultrasonic wave cleaning apparatus as claimed in claim 2, further comprising means for sucking said cleaning liquid from within said cleaning liquid tub and recirculating said liquid to said injecting means.
Claim 5
Dependent Claim
18 words
An ultrasonic wave cleaning apparatus as claimed in claim 3 wherein said sucking means includes liquid pumping means.
Claim 6
Dependent Claim
43 words
An ultrasonic wave cleaning apparatus as claimed in claim 3, further comprising change-over means disposed in said sucking and recirculaTing means to selectively direct said cleaning liquid to said cleaning liquid tub through said pump and said injecting means, or to a drain.
Claim 7
Dependent Claim
31 words
An ultrasonic wave cleaning apparatus as claimed in claim 2 wherein said injecting means includes means for directing the cleaning liquid in a direction generally parallel with said inclined bottom wall.
Claim 8
Dependent Claim
42 words
An ultrasonic wave cleaning apparatus as claimed in claim 1 further comprising an auxiliary liquid tub adjoining said cleaning liquid tub, and weir means between said tubs for overflowing of said cleaning liquid from said cleaning liquid tub into said auxiliary tub.
Claim 9
Dependent Claim
27 words
An ultrasonic wave cleaning apparatus as claimed in claim 1, further comprising filter means adapted to filter said cleaning liquid flowing out of said cleaning liquid tub.
