The operation principle of Fig. 8 and electric wiring shown in Figure 9 is as follows:

External AC power supply is by fusible link (RD ₁) connect and insure relay (J ₃) normally opened contact (J ₃A, b), ordinary circumstance lower contact (J ₃A, b) closure, as following four kinds of situation lower contact (J ₃A) open: (1) operator requires to cut off the electricity supply press button (K _1b) disconnection relay (J ₃) discharge; (2) the big lid of washing machine is opened, with the discharge cock contact (K of big lid interlocking ₆) disconnect relay (J ₃) discharge; (3) in the time of should intaking, water intaking valve solenoid (T ₂) connect relay (J ₄) also attracting electric relay (J ₄) normally-closed contact (J ₄A) reaches (J ₄B) open, no water protector works, as no water protector water pipe (B ₁) in anhydrous then relay (J ₃) discharge; Amplitude overrate, then the sender contact (K of amplitude sensor during (4) as dehydration ₅) action, relay (J ₃) discharge.(J ₃) discharge its switch (J ₃A, b) open, cut off AC power, washing machine quits work.

After all washing dehydration programs finish, cam (Z ₁) " stopping automatically " normally-closed contact of control is opened, cutting off AC power, washing machine quits work.

Finish when washing procedure, enter dehydration procedure before, cam (Z ₄) " shutdown of not dewatering " contact of its control is disconnected, as presetting " not dewatering " button (K this moment ₂A) be in off-state, then washing machine promptly interrupts quitting work, and the clothing in the cylinder is floating in water, waits for after the operator returns and dewatering, only need click button (K again after the operator returns ₂A), ac circuit is connected, and washing machine stops to wait for, continues dehydration procedure.

Cam (Z ₆) in non-dehydration, throw off contacting, break of contact fast at a slow speed all the time with the contact.Subprogram cam (Z ₁) periodically make at a slow speed and just change, the contact of reversing is at a slow speed connected in turn, and pilot process pauses the several seconds, makes the motor positive and inverse action too inviolent.

As cam (Z ₆) be depressed into the contact before, cam (Z ₅) depress earlier to make and just changeing contacting at a slow speed, guaranteeing just changes at a slow speed earlier before fast dewatering, avoids the motor high-speed reverse, and electric current is excessive, causes fusible link (RD ₁) blow.

Cam (Z ₆) depress after, break of contact at a slow speed, contacting fast, this moment is as the sensor (S of water level controller ₁If) water that senses in the cistern do not put, relay (J then ₂) be in attracting state, double-speed motor winding (M ₁) the quick contact (J in the loop ₂A) disconnects double-speed motor winding (M ₁) the high speed winding can not connect double-speed motor line group (M ₁) be in and stop wait state, the water in cistern has been put, sensor (S ₁) middle probe cable (I ₄) and probe cable (I ₅) between because the two probe anhydrous medias that connected, then relay (J ₂) discharge normally-closed contact (J ₂A) connects double-speed motor winding (M ₁) high speed winding energising, so the beginning high speed dewatering.

Electric capacity (C ₁) and electric capacity (C ₂) be respectively double-speed motor (M ₁) the startup electric capacity of high, low speed winding, capacity is 14 μ F, it is directly relevant with the staring torque of motor, and the operating current of also direct and motor, starting current is relevant.

When cam (Z) disengagement made the draining contacting, draining pump motor winding (M) was worked simultaneously with electromagnetic water discharging valve solenoid (T), and washing machine begins draining.

As cam (Z ₃) depress, making into water contacting, the DC voltage by bridge rectifier is added on electromagnetic water inlet valve solenoid (T ₂) two ends, electromagnetic water inlet valve solenoid (T ₂) adhesive, should intake, need this moment to detect whether really water inlet, because electromagnetic water inlet valve solenoid (T by no water protector ₂) the loop connection, cause relay (J ₄) adhesive, make relay (J with voltage divider principle ₄) two ends obtain the 24V dc source, relay (J ₄) adhesive, and no water protector (B ₁) (the J of contact parallel connection ₄B) normally-closed contact is opened, no water protector (B ₁) the contact work, can direct detection have or not water to flow through in the water pipe, as anhydrous as no water protector (B ₁) medium between rapier, then triode (G ₃) be in electronegative potential, relay (J ₃) discharge, the washing machine outage quits work.As water arranged, obvious circuit breaker (J then in managing ₃) adhesive, the washing machine operate as normal.Electric capacity (C ₄) upper end normally-closed contact (J ₄A) also opens this moment, to prevent electric capacity (C ₄) on high potential nowhere Vent put, cause no water protector (B ₁) the contact malfunctioning.At normal washing process cam (Z ₃) mediate, even draining is all disconnected with the water inlet contact.

Cam (Z ₇) depress, should connect heating tube, then sensor (the S of water level controller ₁) middle probe cable (I ₄) and probe cable (I ₅) between two probe anhydrous medias because of being connected, make relay (J ₂) be in release conditions, its contact (J ₂B) opens then heating circuit and can't connect heater heater strip (Q ₁) and (Q ₂) do not work, in order to avoid it is switched under drying regime and causes damage.Has only when in the cistern certain water yield being arranged relay (J ₂) adhesive, allow the heater heating, need heater heater strip (Q certainly ₁) work independently, still need heater heater strip (Q ₁) and (Q ₂) work simultaneously, or all do not work, depend on and preset button (K ₄A) reaches (K ₄B) on off state.

As cam (Z ₈) when depressing, read-me finishes, signalling generator (F ₁) sender, its volume can be used potentiometer (W ₁) transfer in advance appropriate, signalling generator (F ₁) promptly stop voluntarily after sender is tens of second.This moment cam (Z ₁) working makes washing machine be in stopped status.

Route selection wheel (Z ₉) with the cam (Z of main program ₁, Z ₂, Z ₃, Z ₄, Z ₅, Z ₆, Z ₇, Z ₈) synchronously, at any time with the indicator (GD that represents corresponding said procedure ₂, GD ₆, GD ₃, GD ₄, GD ₅, GD ₇, GD ₈, GD ₉) connect, these indicators are light emitting diode and are contained on the console, corresponding demonstration " heating is soaped ", " soaping ", " advancing clear water ", " advancing clear water prewashing ", " discharging water ", " advancing Zao Shui ", " shutdown " and " dehydration ".Light emitting diode sender on the console on the display board is so that the operator comes into plain view to the ongoing program state of washing machine.

Light emitting diode (the GD that the indication of water and water cut-off protection is arranged in the cistern ₁₀, GD ₁₁) directly be connected on relay (J ₂, J ₃) the lower end.When connecting power supply by light emitting diode (GD ₁) show.

Cyclelog motor winding (M ₂) connect with ac circuit, as long as ac circuit is continuous, cyclelog promptly runs well.

To make further supplementary notes to main feature part-structure scheme of the present utility model and operation principle below.

1, cyclelog:

Referring to Figure 10,11,12 and 13, program control motor (M ₂) be installed on the base plate (510) of cyclelog (5), so that fixing and help motor (M ₂) heat radiation.Program control motor (M ₂) on gear by one the cover train (529,530,531,318,532,533) reduction of speed, increased rotating torque simultaneously, make the rotational speed of changeing with per minute one with gear (533) meshed gears (523), the cover of gear (523) stretches in the cam cover (526), drive cam cover (526) with relatively-stationary driving lever (527), when cam cover (526) is stuck, when surpassing the transmission load, soft rubber (520) is compressed by driving lever (527), driving lever (527) is gone up the point that goes out in fact with cam cover (526) and is skidded and mistake, so that gear (523) is unlikely overburden moment being passed to program control motor (XQG-08a) avoids this motor overload to damage, under normal circumstances, geared sleeve (523) drives driving lever (527) rotation, driving lever (527) is being with the cam cover synchronously together with cam by the outstanding point on the cam cover (526) and is being rotated, this cover is that the subprogram cam comprises cam (524) and cam (525), in addition, when geared sleeve (523) rotates, along the circumferential direction this child of child's moving (end of ratch (522) is inserted in the groove of iron plate (307)) is moving every now and then makes the tooth cover (521) that is mated make reduction of speed to rotate for the eccentric circular arc ratch (522) of band, and geared sleeve (523) is 8:1 with the reduction of speed gearratio of tooth cover (521).All be with breach on geared sleeve (523) and tooth cover (521) periphery, the rotary pawl of main program (537) will be to enter the breach of this two-wheeled with the relation of door simultaneously, be that an end of rotary pawl (537) enters that any one breach of taking turns all can not make rotary pawl work in the two-wheeled, have only when rotary pawl to enter breach on the two-wheeled periphery simultaneously, this rotary pawl ratchet (514) that makes main program that just can work rotates a tooth.Ratchet (514) is generally speaking by locating detent (517) location (spring (305) that dependence is enclosed within the axle (304) is pressed to ratchet).

When the driving wheel (523) in the group scheduled cam axle rotates, outstanding small column on this gear (523) drives rocking bar (515), make of the swing of its do less than 90 angles, the ratchet (516) that is contained in during swing on the fork (515) can promote ratchet (514) rotation under the effect of spring (303), but can ratchet (516) fall into and depend on also in the tooth of ratchet whether rotary pawl (537) falls in the breach of geared sleeve (523) and tooth cover (521) periphery circle, as fall into, then when fork (515) when shaking ratchet (516) will push away ratchet and move forward lattice (locating detent (517) let pass lattice).Ratchet (514) bottom related one little tooth, the moving and synchronous gear wheel (538) of main program cam-train of this cingulum, gear wheel (538) turns an angle, and all turn over certain angle with axis cam.

Equal follow procedure need have been made breach and flange on each cam, driving pivoted arm (518) pivoted arm with this is pressed into transition frame (313) and can makes and touch bridge (204) motion, breach by cam, and flange can to determine to touch bridge (204) be to contact with upper contact (205) (209), still contact with lower contact (206) (208), as being the non-again flange of non-breach in this position on the cam, then touch bridge and be stopped at the centre position, all do not contact with upper and lower contact, so only need to change the shape of cam-train cam, just can be by coded program work.

The following describes concrete structure:

(1) on main program cam-train axle, adorns a plastic disc (511), go up installation slip contact (201) at disk (511), this slip contact and main program cam-train rotate synchronously and respectively be installed in fixed underpan (512) on fixed touch plate (203) contact (position of fixed touch plate as shown in figure 10).So, as long as the main program cam-train rotate a unit angle (joint that is ratchet (514) is through radian) slip contact (201) just with corresponding a certain fixed touch plate (203) contact, so corresponding indicator lamp just can sender (referring to Fig. 8 and Fig. 9 (Z ₉) with the relation of light emitting diode (GD)) fixed underpan (512) can make trace and rotate so that aim at the starting point of main program cam.This trace adjustment is to rely on the gap of assembling screw to realize, adjusts position (in hole and screw interstice coverage) at the screw relaxation state and tightens screw again.

(2) on the periphery of gear (523), open the breach of 90 radians at the breach of first-class separately four wide 46 radians of the periphery of tooth cover (521), the starting point that makes 90 breach during installation is alignd with the starting point of arbitrary breach in four 46 breach, so, just can make the relation that produces 2:1 between subprogram and the main program during work, be that subprogram is rotated two all main programs lattice that go forward one by one, the joint that is ratchet (514) makes and makes and assemble and all become simple through radian.

The flange of cam made and touches bridge (204) and be depressed and contact with lower contact when (3) the subprogram camshaft rotated, connect turning to of motor for just changeing this moment, in washing process, touch the only acceptor scheduled cam control of motion of bridge, when main program need enter dehydration procedure, make the flange compressing pivoted arm (518) of corresponding main program cam, force this pivoted arm from obeying the control break of subprogram cam for obeying the control of main program cam, after pivoted arm is depressed, touch bridge (204) and just connect lower contact, motor is forced be in and just changeing state at a slow speed, switch soon contact at a slow speed by another main program cam this moment again, motor is entered is just changeing state fast, and the steering moment that has just reduced motor effectively like this makes the also corresponding reduction of switch current on the major loop.

(4) the cam body shape of main program identical (as shown in figure 15), but the outer rim shape is inequality, only needing that when assembling the middle big aperture of cam is inserted (inserting preceding earlier at the interlayer cementing) in order mutually with big small convex pillar just can make independent cam set synthesize cam-train, because big aperture can not exchange, so when assembling can anti-inserted direction, again because big aperture is all controlled build-up tolerance with big small convex pillar, so two cam dislocation angle tolerances that cooperatively interact can be controlled in the allowed band.Compare with integral cam like this, have easy to process, assembling easily, good manufacturability, be easy to the advantage of update routine.As long as change the wheel-rim shape of certain a slice cam, just can realize when needing to revise subprogram, not resemble integral cam, move a bit and need affect the situation as a whole.

The shape of cam and working procedure thereof are seen Figure 14 and 15.H indication rod 518 contacts with cam cylindrical (φ 48) among Figure 14, and M indication rod 518 contacts with cam base circle (φ 44), and L indication rod 518 contacts with cam root circle (φ 40).H makes the normally-closed contact of relay throw off the normally opened contact closure.M makes the normally closed of relay, and normally opened contact is all thrown off.L makes the normally-closed contact closure of relay, and normally opened contact is thrown off.Among the figure ^H _LRepresent a lattice H in the two lattice programs, a lattice L.Figure repeat circuit row are the heavy weave program for left side 0-228 °, and the right is the flimsy material program for 228 °-360 °.

This cyclelog has tangible characteristics: (1) band shows select switch, and (2) simplify the collocation relation between program and the main program, and (3) main program cam is at control double-speed motor (M ₁) this motor is just changeed before the high-speed starting at a slow speed, each forms the cam of (4) main program with burst combined method, at any time update routine on demand.Prove its reliable operation by experiment.

2, amplitude controller:

Referring to Fig. 3 and Figure 16, getting in touch with operation principle between the relevant assembly with washing machine of each element of the amplitude controller that the utility model provides is as follows: when the cyclelog (5) of washing machine sends instruction, when the double-speed motor of washing machine (4) connection high speed winding begins to dewater, motor (4) drives cylinder (3) rotation, because driving cistern (2) when rotating, the uneven cause of clothing placement location in the cylinder, cylinder (3) on spring shock absorber (13), beat.The amplitude sensor of this amplitude controller (6) is to be installed in cistern (2) and washing machine, housing, between the base plate (12), when cistern (2) amplitude overrate, sensor (6) just sends signal, makes the delay circuit action of amplitude controller, and delay circuit is by amplifier (G ₃) make relay (J ₃) action, thereby the power supply of cut-out motor (4) makes cylinder (3) reduction of speed, until shutdown, and relay (J after the time-delay several seconds ₃) reset again, motor is restarted.Referring to Figure 16, the amplitude sensor that the utility model adopted is the valve jacket (30) that comprises that plastics are made, be installed in the slide bar of a ladder (31) is arranged in the valve jacket (30), in valve jacket (30) and be placed on the stage clip (32) of slide bar (31) ladder D, slide over the adjustment nut (33) on the slide bar (31), the slide block (34) that is threaded with adjustment nut (33), the support (35) that connects the cistern (2) of slide block (34), be rotationally connected with washing machine base plate (12), can in two directions of 90 ° of one-tenth, swing valve jacket (30) bottom (36) by a small margin, be contained in that valve jacket (30) is gone up and by the limit switch (K of the ladder displacement control of slide bar (31) ₅) and support (35) vibration rising extreme position cushion pad (37).Adjust the extreme position (A) of above-mentioned adjustment nut (33) adjustable amplitude, when cistern (2) is being with support (35) up-down vibration, as long as the range of movement of support (35) is no more than extreme position (A), then limit switch (K ₅) be failure to actuate, in case when the position that oversteps the extreme limit (A), limit switch (K ₅) promptly move sender.Support (35) is cushioned by cushion pad (37) when rising to extreme position, unlikely generation noise.

Referring to Fig. 8 and Fig. 9, the delay circuit of this amplitude controller is by two resistance (R ₁₁, R ₁₂), an electric capacity (C ₄) form.Resistance R ₁₁An end connect the 16V dc power anode and the other end connects the limit switch (K in the described amplitude sensor ₅) normally closed joint, resistance (R ₁₂) a termination 16V dc power cathode and the other end connects limit switch (K ₅) normally open contact.Capacitor C ₄One termination limit switch (K ₅), the other end is connected to the 16V dc power cathode; Signal amplifier (G ₃) be the triode transistor amplifier, its base stage connects resistance (R ₉) to the switch (K of delay circuit ₅), emitter stage connects relay (J ₃), colelctor electrode is connected to the negative pole of 16V dc source; Relay (J ₃) and a rectification diode transistor (D ₃) parallel connection, an end connects amplifier (G ₃) emitter stage, the other end connects the positive pole of 16V dc source.Its course of work is as follows: the limit switch (K on amplitude sensor (6) ₅) when moving, switch and resistance R ₁₂Connect and and resistance R ₁₁Disconnect, then electric capacity (C ₄) pass through resistance R ₁₂Repid discharge, triode (G ₃) base potential become electronegative potential from original high potential, relay (J then ₃) transfer release conditions to by original attracting state, double-speed motor (M ₁) disconnection of loop high speed winding loop, relay (J ₃) normally opened contact (J ₃A, b) opens, then motor (M ₁) outage, because motor speed descends, the amplitude of cistern also descends thereupon, then limit switch (K ₅) reset, this moment triode (G ₃) base potential because electric capacity (C ₄) current potential that forms of the RC integrating circuit that constituted raises gradually, reach certain potentials after, relay (J ₃) just adhesive, the purpose of reached instantaneous disconnection like this, delaying time and connecting.The purpose of time-delay is to make the clothing in the washing machine drum can redistribute the position in the process of cylinder reduction of speed rotation, wishes that clothing distributes evenly a bit in cylinder so that cylinder is unlikely owing to be partial to a side and cause and beat when rotating at a high speed, and amplitude is excessive.Experiment showed, generally needs 5-6 time.The time can not be long when motor was connected to delaying time from being cut off power supply, can not be too short, and long, clothing easily is tending towards one more increases the possibility that lays particular stress on, and too short, clothing has little time redistribution, loses the meaning of adjustment, and general delay time is got 3-10 second.

3, water level controller

Referring to Fig. 3 and Figure 17, contact and operation principle between each element of the water level controller that the utility model provides are as follows, connect water intaking valve (T when the cyclelog (6) of automatic control program for washing sends instruction ₂T ₃), the water source is by water intaking valve (T ₂T ₃) to cistern (2) water filling, the water in the cistern (2) is by flowing to level sensor (7) communicating pipe, the water level in water level in the sensor (7) and the cistern (2) is consistent, when water level rises to by selector switch (K ₃) during the rated value of preliminary election, then sensor (7) sends instruction by amplifier (G ₂) make relay (J ₂) action, thereby cut off water intaking valve (T ₂T ₃) electric loop, make electromagnetic valve (T ₂T ₃) close, to cut off the water supply, finish the purpose of water level control.

The water source is water source from the beginning commonly used, and communicating pipe is general rubber tube, selector switch (K ₃) model be 10H-2-20, amplifier (G ₂) be common crystal amplifier.Relay (J ₂) model be JQX-4.

In addition, this water level controller is done the time spent at a dehydration protection, and the operation principle of water level controller is as follows: cyclelog (6) sends instruction, opens water drain valve (8) and should make motor (M ₁) top gear connect, do not put as the water in cistern this moment (2), then the water in the cistern (2) by making sensor (7) communicating pipe thus the contacting of middle probe by amplifier (G ₂) make relay (J ₂) be in attracting state, to cut off motor (M ₁) the high speed loop, reached the purpose that does not allow high speed dewatering when in cistern, water state being arranged, because dewater when in the cistern water being arranged, motor is overload operation, causes damaging, and has only when in the cistern when anhydrous, probe in the sensor (7) is obstructed, makes relay (J ₂) discharge relay (J ₂) normally-closed contact (J _2a) work hard in glove with motor high speed loop, so that the high speed dewatering action can be given realization.

Do the time spent at a heated protective, the operation principle of water level controller is as follows: cyclelog (5) sends command request, connects heater (Q ₁Q ₂) electric loop, and open water intaking valve (T simultaneously ₂T ₃) supply water by the water source, but at this moment as anhydrous in the cistern (2), by also anhydrous in linker, the sensor (7), sensor (7) middle probe is obstructed, by amplifier (G ₂) make relay (J ₂) be in release conditions, the then normally opened contact (J of this relay ₂B) cuts off heater (Q ₁Q ₂) electric loop, heater can't be connected, thereby reached the anhydrous not fair heater (Q that connects ₁Q ₂) purpose, under drying regime, work and damaged with unlikely heater.

Figure 17 illustrates the structure of many probes set probe sensors that the utility model adopts.It is five stainless steel probes different in size (42,43,44,45,50) by joint (46) fixed in position in an elongated shell (41), its middle probe (42) is a public pole, three probes (43,44,45) are that water level is selected the utmost point, be in different water levels place respectively, probe (50) is that the water and the anhydrous detection utmost point are arranged, and is in the bottom position of cistern (2).All probes are all by cable (47), respectively with selector switch (K ₃) and other departments of electric wiring connect, (41) middle part of shell makes on its outer wall that vertically is fixed in above-mentioned cistern (2) with collar (48), patch with communicating pipe (49) sealing of connecting cistern (2) to the lower end, there is an aperture φ 3 to be used for Vent on the shell and puts the interior air of pipe, avoid the degree of accuracy of effects of air pressure water level in the pipe.Probe end is loaded onto the polygonal rubber sleeve that has wedge angle; Purpose is to prevent probe and tube wall because the adhewsive action of water and inhale mutually and paste to cause misoperation.

Because the many probe set of water level controller employing probe-type level sensors, this sensor comprises several probes, and the location of each probe is corresponding to the different water potential sensitivities in the washing machine cistern, reliable, accurate sensing water level; Adopted selector switch, preliminary election is the water level that will control easily.Because accurate multidigit control water level, thereby reach using water wisely and use the soap amount.This water level controller also has simple in structure and the low advantage of cost.
