Dishwasher with at least one crockery rack - has arm supplied from cone below upper nozzle with free air section, surrounded by water curtain

摘要

The dishwashing machine has one or more crockery racks of which at least one has a spray arm beneath it, supplied with cleaning fluid from a collecting cone which gets its fluid from an upper nozzle on the "free jet principle", ie, there is a free air section between upper nozzle and cone mouth through which the fluid falls. To dampen the sound, there is a screen surrounding the cone, upper nozzle and air section. This screen is preferably a "water curtain" of cleaning water produced by a peripheral supply pipe with nozzles, concentric with the central jet of cleaning water and using the same source. ADVANTAGE - Quiet operation of machine.
