Abstract (en)
A dishwasher includes an upper sprinkler (US) and a lower sprinkler (LS) that receive water through respective delivery ducts (UD, LD), 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 two deliveries (D1, D2) toward the respective delivery ducts (UD, LD), as well as a valve system suitable to independently control the water flow in the two deliveries (D1, D2), said valve system including at least one two-position slide valve (SV) with a single inlet and two outlets arranged in one of the deliveries (D1), a first outlet of said slide valve (SV) being directly connected to a first delivery duct (LD), whereas the second outlet is connected to the second delivery duct (UD) through a substantially Y-shaped connector (C). In this way the user can choose between alternate wash and simultaneous wash, and the machine has a more efficient, reliable and cheap structure (both to manufacture and to use) with respect to conventional machines in which the hydraulic circuit includes two shut-off valves for controlling the water flow to the sprinklers.
