Washing Machine Door Endurance Test Machine

 1. Introduction

Washing machine door endurance test machine can meet the requirement of IEC60335-2-7 clauses 18.101 and 22.104, IEC60335-2-11 clause 20.101 and IEC60335-2-4 clause 18, it is a special test equipment applied to life test of lid or door interlock of various washing machines and tensile force test when the interlock device acts to lock the door. The washing machine door endurance test machine can be set flexibly as per different washing machine. The test machine adopts PLC controller and touch screen, and the motor drives the transmission rod to reciprocate the switch movement. It can independently realize the reciprocating action of "opening and closing" the lid and door of washing machine. The rack is made by high grade aluminium alloy, and the door is fixed by a vacuum suction cup structure, which is easy to operate and easy to control.


2. Test principle:

Use the edited program to control the power-on and power-off of the interlocking device, drive the mechanical arm through the motor, and drive the door or lid that is sucked by the vacuum suction cup to reciprocate opening and closing at a certain speed, so as to verify the reliability of the interlocking device. A force sensor is installed on the mechanical arm, which forms a closed-loop control with the servo motor, and can precisely control the closing force value.

The relationship between standards IEC62262 and IEC60068-2-75

  The IK code is a coding system to indicate the degree of protection provided by an enclosure against harmful external mechanical impacts. The standard IEC62262 defines the impact energy corresponding to different IK codes. In general, the degree of protection applies to the complete enclosure. If parts of the enclosure have differing degrees of protection, the latter shall be indicated separately. IK00 IK01 IK02 IK03 IK04 IK05 IK06 IK07 IK08 IK09 IK10 IK11 0 0.14J 0.2J 0.35J 0.5J 0.7J 1J 2J 5J 10J 20J 50J IK00 - no protection IK01 - withstands 0.14J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 56mm on the surface) IK02 - Withstand 0.2J impact force (equivalent to the impact of an object weighing 0.25KG falling from a height of 80mm on the surface) IK03 - Withstand 0.35J impact force (equivalent to the impact of an object weighing 0.2KG falling from a height of 140mm on the surface) IK04 - Withstand 0.5J impact force (equivalent to t...
