Abstract

805,489. Filters; systems of filtration. WHIRLPOOL CORPORATION. Jan. 14, 1957 [Jan. 17, 1956], No. 1386/57. Class 46. [Also in Group XXIII] Washing or rinsing liquid W is pumped at 17 from a filtrate reservoir 11 and sprayed at 20 into the washing zone 12 of a dishwashing machine 10. The liquid, plus solids from dishes D, passes to a foraminous screen 24, some liquid passing through it to the reservoir 11 and the remainder, with all the solids, passing through an aperture 37 in the screen, down a pipe 36 and into a sump 32 which, during operation of the pump 17, does not communicate with a drain 34. Liquid from the sump 32 passes upwards through a foraminous screen 41 surrounding the lower end of the tube 36 into the reservoir 11. At intervals the pump 17 is stopped and a grinder in a disposal unit 31 is started, whereupon solids collected in the sump 32 are ground and passed to drain 34. At the same time some liquid from the reservoir 11 is discharged to drain, effecting backwashing of screen 46 (see below) and screen 41 on the way. The screen 24 is secured by spring clips 26a engaging the edge 27 of an opening 23 in the floor of the washing zone and tube 36 is attached by welding or otherwise to the screen 24. When the assembly is removed for cleaning, dirt is prevented from reaching the pump 17 by a cylindrical foraminous screen 46 located between the screen 24 and the floor 29 of the reservoir 11.
