Washing Machines Electrical Appliance Testing Equipment For Lid Interlock Endurance & Pull Test

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

IEC60335-2-24:2017 “Household and similar electrical appliances-Safety-Part2-24:Particular requirements for refrigerating appliances, ice-cream appliances and ice-makers, IDT” 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.
