IEC60335-2-14 Electrical Refrigerator Freezer Appliances Door Open Endurance Testing Machine
Standards & Clauses:
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:
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 the door for refrigerators and freezers, 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 door repeated opening and closing operations of refrigerators and freezers, such as the defrost test and refrigerant leakage test.
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 at a certain speed with vacuum suction cup sucking on the door, thus, to verify the stability 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 opening/closing force values.
Structure:
The equipment combines of electrical control cabinet (including load voltage regulating device), frame and manipulators.
Equipment dimensions: approx.: (W*D*H)1500 * 1300 * 2200 (mm)
