12.2 Detergent dispenser
12.2.1 Detergent dispenser with multi-way solenoid valves
The water in the detergent dispenser is filled through a solenoid valve for cold water (with one inlet, and 2 or
3 outlets) and where featured one for the hot water (with one inlet and one outlet).
The detergent dispenser has 4 compartments.
Tray conveyor
4-way water inlet nozzle
12.2.2 Operating principle of 4-compartment conveyor
Water fill to pre-wash compartment
(pre-wash solenoid)
This solution is used with the four compartment tray: the
detergent in compartment
“a” is loaded at the start of the
pre-wash phase.
Water fill to wash compartment
(wash solenoid)
In all models: compartment
“b” is used to contain the detergent
loaded at the start of the washing.
Water fill to activating wash compartment
In models with 4-compartment dispenser trays, the filling in
tray
“d” is performed by a purpose-provided solenoid valve
during washing, when the water has reached 40°C.
In models with 3-compartment dispenser trays, this section
is not used.
Water fill to conditioner compartment
(pre-wash and wash solenoid valves)
In all models: compartment
“c” is used for the conditioner,
which is loaded at the start of the final rinse. The prewash
and wash solenoid valves are activated simultaneously.
Hot water filling
(hot water solenoid)
In models with a hot water solenoid valve, the hot water solenoid
valve is activated to fill water into the wash compartment.
