The card program-control device can compile various programmed cards according to different model capability, clothing textures and smudge situations. The utility model not only achieve the full automation washing function, and also has the advantages of simple structure, convenient operation, strong applicability, low cost and wide program selection.

Description

Card programme-control device for washing machines

The utility model is the mechanical process controller that is used for all kinds of automatic washing machines.

Its control system of the washing machine of Xiao Shouing has two kinds of computermatic and mechanical types in the market.Computer is controlled used cost height, not too adapt to China's resident living level, the control of common mechanical formula, the requirement on machining accuracy height, the parts complexity is various, control range is narrow, wanting to increase function must increase a plurality of parts, as Chinese utility model patent 85205668, and (August 12 87 year day for announcing) October 7 87 year 86210556(day for announcing) be exactly like this.

The purpose of this utility model is, designs a kind ofly can satisfy the full-automatic requirement of laundry, makes it simple in structure, easy to operate again, the cyclelog of low cost of manufacture.

Technical solution of the present utility model is: be used for the mechanical programmed controller of automatic washing machine, it is characterized in that having one group of functional switch and a series of circular control card and gear.Handle that touches by the spring restriction is arranged on the functional switch, have on the support of functional switch by touching the contact that handle drives; Position corresponding to each functional switch on the chip card is divided into several concentric circles, has scarce hole on concentrically ringed camber line, is divided into 60 equal portions along circumference, and the concentrically ringed arc length in each part place is a unit interval distance; By the rotation of chip card, make functional switch touch handle and jump in the scarce hole on the card, drive the contact, reach the control purpose.The utility model adopts the micro machine driving main shaft that card is rotated, the micro machine rotating speed after the one-level speed change that adopts 3-5 rev/min of output speed is 1 rev/min and drives cam 17, at least through two stage speed change main shaft 6 being changeed/hour rotation with 1, is good to adopt the level Four speed change generally.

Below in conjunction with accompanying drawing technical solution of the present utility model is elaborated.

Fig. 1 is the overall structure figure of this cyclelog.Pinion 2 is installed on the output shaft of permagnetic synchronous motor 1, after change-speed gearing 3,4,5 speed changes, the speed of passing to main shaft 6 be 1 change/hour, main shaft 6 is connected with chip card 10 by connecting shaft flange 7, rubber cushion 8, pressure cap 9, water inlet functional switch 11 has been installed below card 10, washing, rinsing functional switch 12, drainage switch 13, dry switch 14, buzzing switch 15 and cut-off switch 16, cam 17 is installed on the gear 3, with rotating and reverse of control washing motor, control reed 18 is fixed on the insulation board 19.

Fig. 2 is the structural representation of water functional switch 11 into.Spring 26 is fixed on the bearing support 27, touches handle 20 and two-sided contact 22 interlocks, and

stationary contact

21,23 is separately fixed on the

tubular rivet

25,26 of

insulation board

19, and 21,22,23 is the contact.

Fig. 3 is the structural representation of

functional switch

12,13,14,15,16.The difference of it and functional switch 11 has been a stranded copper wire connecting line 28, to guarantee the good contact of electricity, improves the reliability of actions such as laundry, drying, buzzing, outage.

Fig. 4 is the wiring diagram of controller.

Fig. 5 is the special case of a kind of program of control card 10, is coated with crucial point and represents to lack the hole.

When card 10 is placed on the main shaft 6, card 10 is in 0 place of starting point, contact 22 and 23,32 and 33 equal Closed control motor 35 startings, card 10 begins to rotate, the inlet function switch touch handle 20 under the effect of spring 26, jump into scarce hole 20 on the card 10 ' in, contact 22 and 23 disconnects, 21 and 22 closures, 35 outages of control motor, entering water electromagnetic valve 34 work, water inlet indicator lamp 47 is bright, when water inlet reaches highly, water level pressure switch contact 45 and 46 closures, 35 work of control motor, card 10 is rotated further, functional switch touch handle 40 jump into scarce hole 40 on the card 10 ' in, contact 24 and 25 closures, motor 36 work, washing beginning, wash time by lack hole 40 ' length control, when card 10 forwards for 41 ' time to, touch handle 41 and jump into

contact

26 and 27 closures, water-drainage solenoid valve 37 work, addle is bled off, and card 10 is rotated further, touch handle 42 and jump into 42 ' in, contact 28 and 29 closures, drying motor 38 work dry beginning, continue it, through 20 "; 40 ", 41 "; 42 " carry out a rinsing, as required, work out different cards and can carry out repeatedly rinsing, when card 10 forwards for 43 ' time to, touching handle 43 jumps into, contact 30 and 31 closures, buzzer 39 work, tactile handle 44 is jumped into the 44 ' time of scarce hole on the card 10 at last, the complete machine outage, it is complete to do washing. 47,48,49,50,51 be respectively into water among Fig. 4, wash, discharge water, dry, power up indicator lamp.

The utility model has the advantage of simple in structure, function is more, the procedure Selection wide ranges, strong adaptability, it does not require accurate processing and realizes reliable action, simultaneously, it can make washing machine dial plate simplicity of design, except various functional indicator lights, and none shift knob of dial plate, and with low cost, economical and practical.

Embodiment: used control micro machine 35 adopts homemade permagnetic synchronous motor in this programme, 5 watts of power outputs, and rotating speed is 5 rev/mins, the gear ratio of gear 3 is 5:1, then after the one-level speed change is 1 rev/min.Cam 17 of this rotating speed control makes it to realize the forward and backward of washing motor and intermittently control; Two stage speed change is than being 5:1, and the three-step gear shift ratio is 6:1, and the level Four gear ratio is 2:1, and then final main shaft 6 changes/a hour drive card 10 rotations with 1.Control card can be made with a millimeters thick epoxy resin or other laminated board, is divided into 60 equal portions on the card circumference, when per hour 1 when changeing, the time that turns over 1 equal portions is 1 minute, and flooding time is 1 minute on the program card that Fig. 5 gave, and is 8 minutes during washing, the drying time is 3 minutes, discharging water is 2 minutes, secondary water inlet 1 minute, rinsing 5 minutes, dry 4 fens, discharged water buzzing 1 minute, outage at last 3 fens.Functional switch in this programme is homemade, and switch contact is decided according to watt level, and each switch must be in alignment, and the concentric circles spacing matches on the distance of each switch room and the card, is fixed on the insulation board 19.
