Embodiment
Understand for the ease of those skilled in the art, the utility model is done further explain below in conjunction with accompanying drawing and specific embodiment.
With reference to accompanying drawing 1, a kind of fully automatic roll type washing machine fault principle and diagnostic teaching instrument comprise Digiplex and testing tool, are provided with wireless transmitter module in the Digiplex; Said testing tool comprises single-chip microcomputer, driving circuit, wireless receiving module, relay group, display module and power reset oscillatory circuit, and wireless receiving module is used for matching with Digiplex and its output is connected with input of single chip; The control output end of single-chip microcomputer is connected with the relay group via driving circuit, and the relay in the relay group is arranged in the washing machine electric elements circuit; Display module is connected with the data-out port of single-chip microcomputer.
Among the utility model embodiment, said Digiplex comprises 8 tunnel wireless transmission signal; The frequency of operation of said wireless transmitter module and wireless receiving module is 315MHz.
Among the utility model embodiment, the normally closed form with serial or parallel connection of the relay in the said relay group is arranged in the corresponding circuit.
With reference to accompanying drawing 2, this course of work of washing machine comprises into processes such as water, washing, rinsing, draining, drying, and the automatic synchronization work under the control of single-chip microcomputer of each process is carried out successively.Washing machine is when operate as normal, and through pressing the response button on the Digiplex, washing machine will get into abnormal patterns.Show corresponding error code on the screen simultaneously, the student can be according to the washing machine abnormal occurrence, and the failure judgement position also attempts repairing.The teacher can grasp the Students'learning situation through the correctness of student's judgement.
The utility model course of work is following: after the testing tool energising, and the washing machine non-fault; Select fault mode, when pressing certain button of Digiplex, the contact of corresponding relays can become disconnection by connection, and fault produces thus.
Under teacher's demo mode; Show failure cause on the display module; As long as so the teacher presses the Digiplex response button when the demonstration fault, simultaneously power lead is connected to the normal domestic AC power of 220V, washing machine can produce fault and point out the guilty culprit position automatically.
Under the student experimenting pattern, need earlier the model selection button to be selected in student's pattern, break off all switches of testing tool then, display screen only shows the respective digital code, and teacher's Long-distance Control washing machine produces fault and student oneself judgement again.For example: 1) water inlet fault: closed safety switch SA
2After, press " startup/time-out " switch S B
1, single-chip microcomputer sends signal controlling water inlet control VTH
1, the entering water electromagnetic valve energising is opened, and begins the water inlet process.Press telepilot water inlet fault key this moment, the outage of water intaking valve solenoid valve, washing machine stops into water.2) washing fault: the Single-chip Controlling washing machine begins to wash motor main story reversal switch VTH under preset program
1And VTH
3Open and close successively, the control motor is carried out the circulation of " just changeing → stop → reverse → stop ", makes clutch coupling drive washing tub rotation carrying out work.Press Digiplex washing fault key this moment, washing suspends, and cylinder stops operating.3) draining fault: Single-chip Controlling tractor work during drainage procedure, row's T-valve is opened under the effect of tractor U, carries out draining.Press the draining fault key on the Digiplex this moment, and washing machine is not in draining.4) rinsing fault: water inlet earlier before the washing machine rinsing, water completely back is carried out rinsing by pre-set programs.Press rinsing fault key this moment, and washing machine inflow is more than, can't get into rinsing program.5) dry fault: the Single-chip Controlling motor just changes at a high speed in the drying process, and clothing leans on dehydrate in washing tub.Press the drying fault key on the Digiplex this moment, the washing machine drum rotating speed descends, even stops, and can not reach the drying purpose.6) fuser malfunction: in the washing process, washing machine can be realized the temperature configure water temperature being heated according to the user.Press the fuser malfunction key on the Digiplex this moment, washing machine can't heat or can't stop heating.7) counter fault: single-chip microcomputer guides washing machine to accomplish washing procedure through control program and controls wash time.Press the time failure key of telepilot this moment, and washing machine can not withdraw from current washing state, and washing is more than or dry more than.8) latch failure: the roller washing machine door lock is the important insurance mechanism of full machine, prevents that the user from opening washing machine midway and causing unnecessary loss.If press the latch failure key on the Digiplex, washing machine also can normally get into washing procedure or in washing process, can open door of washing machine under the situation of not closing the door.
The utility model is simple to operate, visual and understandable, safe and reliable, with low cost, and the school and the corporate training that can supply to offer the washing machine correlated curriculum are selected for use.
Above embodiment only be used to explain the utility model technical scheme but not to its restriction; Although the utility model is specified through embodiment; Under the field personnel should make amendment or the part technical characterictic is equal to replacement with reference to the concrete mode of the utility model; But under the spirit that does not break away from the utility model technical scheme, above-mentioned change or be equal to replacement and should belong in the technical scheme scope that the utility model asks for protection.
