IEC60335-2-11 Drum Washing Machine Door Endurance 200N 1.5m/s PLC
Control Testing Equipment
Standards & Clauses:
IEC60335-2-11:2008 “Household and similar electrical
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
IEC60335-2-4:2006 “Household and similar electrical
appliances-Safety-Part2-4:Particular requirements for spin
extractors” clause 18
Samples and Restrictions:
Electric tumble dryer, electric washing machine (including pulsator
and tumble type single phase ≦ 250V, other ≦ 480V), spin extractors
(Load capacity ≦10kg, tumble line speed ≦50m/s, single phase ≦250V,
other ≦480V)
Application:
It is used to test the durability of the interlocking device of
washing machine 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 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.
