Description

A kind of soy bean milk making machine

Technical field

The present invention relates to food processing equipment fields, the in particular to control technology of soy bean milk making machine.

Background technique

When soy bean milk making machine carries out food processing, is crushed, stirred or cleaned according to the difference of food and manufacture craft Deng movement, completion is driven by motor in these movements, and the speed difference between these movements is larger, needs when such as crushing The revolving speed of 10000rpm or more, and stir and clean the revolving speed for then needing 1000rpm or so.

Soy bean milk making machine generally controls motor using electronic switching devices such as silicon-controlled or relays at present, and to its revolving speed It is adjusted.But the speed adjustable range of electronic switching element is difficult to cannot achieve motor up to 1000rpm~10000rpm Slow-speed of revolution control, reaches the functions such as stirring, cleaning and peeling.It is excessive there are electric motor starting electric current and make an uproar in addition, when electric motor starting The excessive phenomenon of sound.

Fig. 1 is soy bean milk making machine prior art working principle block diagram, and FUSE1 is total protective tube, and RG1 is resistive heating load, TK1 For temperature controller, RS1 is thermal fuse-link, and S1 is heating branch switch;MT1 is direct current generator, and DB1 is that (such as MT1 is to hand over to rectifier bridge stack Galvanic electricity machine does not have to DB1 rectification then and the input terminal of DB1 is directly applied to MT1), FUSE2 is electric motor protecting protective tube, and S2 is electricity Machine branch switch.2 feet of DB1 directly connect with the N line of power supply, and whether uncontrollable motor branch and resistive heating load circuit Series connection.When motor for soymilk machine starts, motor is directly initiated or motor start-up procedure is short, causes electric motor starting electric current big, is easy Greater impact is caused to motor and power grid, reduces electrical machinery life, starting noise is larger, influences user experience.Meanwhile it cannot achieve The slow-speed of revolution of motor is controlled to reach the functions such as stirring, cleaning and peeling.

When motor for soymilk machine starts, motor is directly initiated or motor start-up procedure is short, causes electric motor starting electric current big, is held Greater impact easily is caused to motor and power grid, reduces electrical machinery life.Meanwhile when electric motor starting, starting noise is larger, influences user Experience.A kind of (patent in such a way that control thyristor operating angle realizes soft starter for motor and soft switching of existing patent disclosure 114893.1) application number 200910, is illustrated in figure 5 a kind of implementing circuit conceptual scheme of the prior art, wherein TRC1 is controllable Silicon.But there are biggish defects for the program:, and can since thyristor operating angle is controlled according to ac zero-crossing point signal Control silicon triggering needs certain time, if silicon-controlled in very big angle of flow triggering, zero passage detection slightly deviation is just easy to out Existing motor vibrating phenomenon (thyristor operating angle controls concrete principle and refers to the hereafter elaboration to Fig. 6 to Fig. 9), causes simple controllable The starting current of motor and starting noise can not be effectively reduced for the control of the silicon angle of flow.

Thyristor operating angle control:

As shown in figure 8, alternating current divides after D1 half-wave shaping by resistance R11, R12, capacitor C8 fills voltage detecting circuit Electric discharge, capacitor C7 filtering, exporting voltage Vad, MCU a detection Vad voltage value may know that ac voltage.

Zero cross detection circuit as shown in figure 9, alternating current triggers the on-off of Q2 after D2 half-wave shaping after R11 and R12, when ZERO is detected as low level when R12 reaches Q2 trigger voltage, otherwise detects high level, MCU detects that low and high level then detects Alternating current zero crossing.

The prior art is generally worked using thyristor operating angle control mode driving motor as described above, due to controllable The silicon angle of flow is to be controlled according to ac zero-crossing point signal, and control machines need certain time, if led in very big Current flow angle triggering is silicon-controlled, and zero passage detection slightly deviation, just it is easy to appear motor vibrating phenomenons, although so the prior art can be with Controlling motor still can effectively crush material in lower rotary speed working, but when motor work.

Therefore, when soy bean milk making machine needs to clean material, when the prior art controls motor work, it is complete material to be destroyed The purpose of cleaning material is not achieved in whole property;

When soy bean milk making machine needs to carry out the materials such as soybean peeling operation, the prior art controls motor work can be by soy meal It is broken, it is unable to satisfy requirement;

It when soymilk grinder congee, rice paste, mixed congee etc., needs to be stirred material, prevents material sticky end (production rice When the functions such as congee, long-time infusion is needed, it is easy to material sticky end phenomenon occur), although when prior art control motor work While can achieve the purpose of stirring, but stir also can comminuting matter, often congee has finally been stirred into rice paste, Wu Faman Sufficient desired effect.

By increasing by 1 two-way switch, in motor work, it is closed at switch S4, disconnects switch S3, resistive heating is negative It carries circuit and seals in motor branch, because resistive heating load itself has certain resistance, sealing in resistive heating load partial pressure is reduced Motor speed realizes the ultralow revolving speed control of motor.

The specific working principle of Fig. 3 scheme is as follows:

In electric motor starting, S1, S3 can be disconnected, S2, S4 are closed, at this time motor MT1 and resistive heating load RG1 It is cascaded, to reduce starting current, startup power and starting noise.

After electric motor starting, S4 can be disconnected again, S3 closure, motor MT1 is directly connected to power supply at this time, to make electricity Machine enters the working condition of total power.Because motor has had certain revolving speed before entering full power operation state, Reduce starting current, startup power and starting noise.

As a preference of present embodiment, it is illustrated in figure 4 the implementing circuit figure of soy bean milk making machine.Pass through relay in figure Device K1 and silicon-controlled TRC1 realizes heating branch switch and motor branch switch, realizes third switching device by relay K2, It includes a movable contact and two stationary contacts.The movable contact of K2 is connect by DB1 with the second end of motor MT1.The first of K2 Stationary contact is connect with the first end of the first resistive heating load RG1.The second stationary contact of K2 and the second end N line of input power connect It connects.

The working principle of Fig. 4 scheme and Fig. 3 scheme are essentially identical, and difference is only with a relay K1(i.e. single-pole double throw Electronic switch) instead of the S1 and S2 in Fig. 3, the electronic switch of a relay K2(i.e. single-pole double throw) instead of in Fig. 3 S3 and S4.For relay K1, when movable contact 1 is connect with stationary contact 2, it is equivalent to S2 closure S1 and disconnects;When movable contact 1 with When stationary contact 3 connects, it is equivalent to S1 closure S2 and opens.Relay K2 is equivalent to when movable contact 1 is connect with stationary contact 2 S3 is closed S4 and disconnects;When movable contact 1 is connect with stationary contact 3, it is equivalent to S4 closure S3 and opens.

In Fig. 4 scheme, because having used silicon-controlled TRC1, it is possible to dynamically adjust motor MT1 in a certain range With the size of current on negativity heating load RG1.There are two types of situation, the first situations for the dynamic adjustment of silicon-controlled TRC1 in Fig. 4 It is that motor MT1 is directly connected to power supply, silicon-controlled TRC1 carries out the dynamic adjustment of revolving speed on the basis of motor is high-revolving at this time. Second situation is that motor MT1 connects with negativity heating load RG1, at this time silicon-controlled TRC1 on the basis of the motor slow-speed of revolution into The dynamic of row revolving speed adjusts.Revolving speed adjustment only in the case of the first in the prior art, motor speed is controlled lower When, thyristor operating angle will be very big, so as to cause motor vibrating phenomenon (analysis in detail in background technique).And in Fig. 4 scheme, Because of the adjustment under having second situation, the original revolving speed of motor is not just high, just in lesser thyristor operating angle Motor speed can further be turned down, so considerably increasing the effective Dynamic Speed adjusting range of soy bean milk making machine on the whole.

Therefore, when being cleaned using present embodiment control motor to material, material integrality will not be destroyed, object is met Expect cleaning requirement;When carrying out peeling operation to materials such as soybean using present embodiment control motor, because motor speed is very low, Only can to damage skin of beancurd, will not milling soya seeds, meet peeling require;Agitating function is realized using present embodiment control motor When, material will not effectively be crushed while ultralow rotary speed working, stirring due to can control motor, material sticky end can be solved Problem.

Present embodiment compared with prior art, may be implemented the ultralow revolving speed control of motor, not only can satisfy existing skill The mashing of art crushes demand, and may be implemented to stir, and cleans, the functions such as peeling.

Present embodiment can make slurry temperature more uniform, promote temperature sensor thermometric accuracy.Existing soy bean milk making machine When production cooking, since resistive heating load is in bottom of cup or side, cause material uneven heating in cup body even, so cup body Close to resistive heating load part and far from resistive heating load part there are the temperature difference, temperature sensor can not be examined accurately interior material Cup body temperature is surveyed, the release of effects on slurry making and nutritional ingredient is influenced.In resistive heating load heating process, slurry is stirred at interval can So that cup body temperature is uniform, temperature sensor thermometric accuracy is promoted.But when prior art control motor stirs slurry, while can be right Material is effectively crushed, and normal slurrying process and effects on slurry making are interfered.Present embodiment can control motor in ultralow revolving speed Work, stirring while will not effectively crush material, temperature sensing caused by non-uniform temperature in very good solution cup body Problem is not allowed in device thermometric.Compared with prior art, cost is cheaper for which, can satisfy while the application heated and be beaten needs It asks.It heats and is beaten simultaneously, save the slurrying period.And be beaten in small-power infusion, it can prevent in sticky end and cup body Temperature is more uniform, promotes temperature sensor thermometric accuracy.

When only needing the independent full power operation of motor, S1 can be disconnected, S2 and S3 is closed.

When only needing the independent full power operation of resistive heating load RG1, S2, S3 can be disconnected, S1 is closed, is hindered at this time Property heating load RG1 is directly connected to power supply, and motor MT1 stops working.

When needing the motor slow-speed of revolution, S1, S3 can be disconnected, S2 is closed, resistive heating load RG1 is concatenated into electricity at this time In machine branch, motor speed can be dropped lower.
