Owing to adopt said structure, the aging emulation test method of the present invention's washing machine program controller has following beneficial effect:
1. cost is low, occupied ground is little:
The emulation testing of wear out is that the detecting signal unit detection water filling tractor through the washing machine program controller, the signal of water discharge dragging device are judged the duty of washing machine program controller because the present invention is to the washing machine program controller; Thereby select the water level of wanting of washing machine program controller; Automatically switch the then shelves of water level, desired water level when satisfying the operation of washing machine program controller.And in the process of the aging emulation testing of washing machine program controller; Maximum technological difficulties are exactly the water level simulation; The water level simulator that the present invention adopted is designed with two kinds of water level frequency meters, and a kind of is the low-water level frequency meter of low-water level state, can satisfy the anhydrous condition of work of washing machine program controller; A kind of is the high water stage frequency meter of high water stage state, can satisfy the full condition of work of washing machine program controller water.Therefore, the present invention can imitate washing machine more truly and make the operation of computer program controller continuous uninterrupted, need not washing machine of every suit washing machine program controller product outfit and carries out burn-in test, and its cost is lower, also need not take bigger production site.
2. applied widely:
The functional test of washing machine program controller products such as the present invention's ability emulation plain edition, fuzzy type, impeller-type, stirring-type, drum-type, its scope of application is wider.
3, method is simple, simple operation.
Below, in conjunction with accompanying drawing and embodiment the technical characterictic of the present invention's the aging emulation test method of washing machine program controller is further described.
