appliances-Safety-Part2-11:Particular requirements for tumble
dryers” clause 20.101
IEC60335-2-7:2016 “Household and similar electrical
appliances-Safety-Part2-7:Particular requirements for washing
machines” clause 18 and 22.104

clause 22.112
Samples and Restrictions:
Electric tumble dryer, electric washing machine (including pulsator
and drum type single phase ≦ 250V, other ≦ 480V), spin extractors
(Load capacity ≦10kg, tumble line speed ≦50m/s, single phase ≦250V,
other ≦480V), refrigeration appliances (refrigerators and
freezers,which door is opened left and right) (single phase ≦ 250V,
other ≦ 480V, DC ≦ 24V)
Application:
It is used to test the durability of the interlocking device of
washing machines, refrigerators and freezers door or lid,, and the
force test when the interlock is actuated, so as to verify the
reliability of the interlocking device; also used to assist other
tests for repeated opening and closing operations of the washing
machine /refrigerato / freezer door or lid.
Test Principle:
The on/off actions of the interlocking device are controlled
through developed program, the manipulators are driven by servo
motor to reciprocating open and close the door or lid at a certain
speed with vacuum suction cup sucking on the door or fixture
clamping the lid, thus, to verify the reliability of the
interlocking device. A force sensor is mounted on the manipulators
to form a closed loop control with the servo motors, to accurately
control the door or lid opening/closing force values.
Structure:
The equipment combines of electrical control cabinet (including
load voltage regulating device), frame and manipulators. There are
two testing station, one is for tumble washing machine with door,
the other is for pulsator washing machine with lid, the two
workstations can process testing independently.
Equipment dimensions: approx.: (W*D*H)2500 * 1300 * 2200 (mm)
Equipment weight: 250kg
Use Environment:
Power supply: AC220V±10%/ 50-60 Hz, power 6KW or match client's
local power supply.
