Abstract (en)
A dishwasher includes an upper sprinkler (US), a lower sprinkler (LS) and a ceiling sprinkler (CS) that receive water through respective delivery ducts (UD, LD, CD), on the bottom of the washing tank there being arranged a collecting sump (S), a suction duct (SD) branching out from the bottom of the latter and leading to a wash pump (P) provided with a delivery (D) in which there is arranged a three-way valve (V) with a single inlet and three outlets, that includes a rotating shutter (RS) suitable to be alternately aligned with one of the three outlets while shutting the other two, the three delivery ducts (UD, LD, CD) being each connected to one of these three outlets. In this way it is possible to achieve the same function of alternate wash combined with the ceiling sprinkler (CS) without having to increase the water load, and therefore without any increase in water and power consumption, as well as in noise; moreover, the ceiling sprinkler (CS) can have a flow rate equal to that of the rack sprinklers (US, LS), whereby the washing effectiveness is increased.
