According to the test method of temperature control stability of the refrigerator of the embodiment of the present invention, by simulate refrigerator external environment condition, such as simulating the external environment condition such as hot and humid, to accelerate refrigerator aging and then carry out burn-in test to refrigerator, and carry out switch testing by the start-stop of electric control element on the circuit board of acceleration refrigerator, the operation of real simulation refrigerator, thus the serviceable life of refrigerator can be tested out accurately, there is test refrigerator life cycle advantage accurately, test result is with a high credibility, and then provide reliable reference for follow-up exploitation, and the method is implemented simple.
In one embodiment of the invention, in the burn-in test of described refrigerator and the process of switch testing, the load of described refrigerator is adjusted.
In one embodiment of the invention, described multiple automatically controlled device comprises compressor, blower fan, lamp and damper motor.
In one embodiment of the invention, the switch periods of described switch testing is 1-3s.
In one embodiment of the invention, with preset order, switch testing is carried out to described multiple automatically controlled device.
Additional aspect of the present invention and advantage will part provide in the following description, and part will become obvious from the following description, or be recognized by practice of the present invention.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present invention and advantage will become obvious and easy understand from accompanying drawing below combining to the description of embodiment, wherein:
Fig. 1 is the process flow diagram of the test method of temperature control stability of a kind of refrigerator according to the embodiment of the present invention; And
Fig. 2 be the test method of temperature control stability of a kind of refrigerator according to the embodiment of the present invention carry out with multiple electrical control member the process flow diagram tested successively for every 2S start-stop.
Embodiment
