VARIABLE FLUX APPARATUS OF WASHING WATER IN DISHWASHER BACK NOZZLE

摘要

A variable flow apparatus of washing water of a back nozzle in a dishwasher is provided to expand the washing injection range through an injection hole of an injection arm by periodically changing flow of washing water distributed to each the injection arm of the back nozzle, and to improve washing efficiency by efficiently separating pollutant from tableware. A variable flow apparatus of washing water includes a distribution chamber(10) communicated with a passage pipe for distributing washing water to injection arm passages(4a,5a,6a) of a back nozzle(1), and a flow regulating unit installed in the distribution chamber to regulate the rate of washing water distributed to the injection arm passages. The flow regulating unit has a passage shutoff plate for periodically opening and closing the injection arm passage by turning according to supply pressure of washing water. The flow regulating unit has a first gear(20) installed in a washing water inflow unit and turned by supply pressure of washing water, and a second gear(30) engaged with the first gear and turned by interlocking with the first gear. The passage shutoff plate is installed in the second gear and turned to open and close the passage.
