Further technical scheme of the present utility model is: described water level simulator comprises low-water level frequency meter and high water stage frequency meter, and this low-water level frequency meter is connected input port and is connected with the output control signal unit output port of laundry machine programmer controlled system respectively with the high water stage frequency meter.
Again further technical scheme of the present utility model is: the aging simulating and testing instrument of described laundry machine programmer controlled system also comprises motor, and the input end of this motor is connected with the output control signal unit output port of laundry machine programmer controlled system.
The aging simulating and testing instrument of described laundry machine programmer controlled system also comprises water discharge dragging device, and input end of water discharge dragging device is connected with the output control signal unit output port of laundry machine programmer controlled system on this.
The aging simulating and testing instrument of described laundry machine programmer controlled system also comprises the hand rubbing tractor, and the input end of this hand rubbing tractor is connected with the output control signal unit output port of laundry machine programmer controlled system.
The aging simulating and testing instrument of described laundry machine programmer controlled system also comprises the electrical heating tractor, and the input end of this electrical heating tractor is connected with the output control signal unit output port of laundry machine programmer controlled system.
Owing to adopting said structure, the aging simulating and testing instrument of the laundry machine programmer controlled system of the utility model compared with prior art 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 by laundry machine programmer controlled system, the signal of water discharge dragging device are judged the duty of laundry machine programmer controlled system because the utility model is to laundry machine programmer controlled system, thereby select the water level of wanting of laundry machine programmer controlled system, then the automatically switch shelves of water level, desired water level when satisfying the laundry machine programmer controlled system operation.And in the process of the aging emulation testing of laundry machine programmer controlled system, maximum technological difficulties are exactly the water level simulation, the water level Simulator design that the utility model adopts has 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 laundry machine programmer controlled system; A kind of is the high water stage frequency meter of high water stage state, can satisfy the full condition of work of laundry machine programmer controlled system water.Therefore, the utility model can imitate more truly washing machine and make the continuous continual operation of computer program controller, need not washing machine of every suit laundry machine programmer controlled system product outfit and carries out burn-in test, and its cost is lower, also need not take larger production site.
2. test is reliable:
Because the utility model is except including water filling tractor, water discharge dragging device and water level simulator, also include motor, upper water discharge dragging device, hand rubbing tractor, electrical heating tractor even load, not only can simulate the water position status of washing machine, can also simulate the duty such as upper draining, hand rubbing, electrical heating of rotating duty, the washing machine of motor for washer.Therefore, the utility model can imitate the various duties of washing machine more truly, thereby the aging emulation testing that laundry machine programmer controlled system is carried out is also reliable.
3. applied widely:
The functional test of the laundry machine programmer controlled system products such as the utility model energy emulation plain edition, fuzzy type, impeller-type, stirring-type, drum-type, its scope of application is wider.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of the aging simulating and testing instrument of the laundry machine programmer controlled system of the utility model is further described.
