The multifunctional soya bean milk process or with an electric control device can not only be used for processing soybean milk, but also can be used for heating water, heating milk, cooking coffee, cooking rice water, etc. The utility model is the machine with multifunction.

Description

Multifunctional soyabean milk process or with an electric control device

The utility model is a kind of device about Automatic Detection and Control heating and running.

The electric control system of existing soya-Bean milk processer is the circuit complexity not only, the cost height, and soya-bean milk does not boil sometimes, and this machine just quits work, and function singleness.The purpose of this utility model is simplified circuit exactly, reduces cost, and improves the reliability of performance, and by the change-over circuit switch, also can heat up water, burns milk, makes coffee, cooks gruel etc. and become a tractor serves several purposes.

After the purpose of this utility model was achieved in that and is boiled by slurries, liquid level changed, and adopted special IC to realize that the differentiation of this state removes control heater and motor, and the conversion by contactor simultaneously realizes function conversion.

Below in conjunction with the utility model is described in detail shown in the figure:

Accompanying drawing 1 is the electric control theory figure of multifunctional soya-bean milk processing machine, wherein ［ 1 ］-prosecution circuit; ［ 2 ］-Electric Machine Control and warning circuit; ［ 3 ］-delay circuit; ［ 4 ］-power supply.

Accompanying drawing 2 is the utility model appearance assumption diagrams, wherein ［ 5 ］-shell, ［ 6 ］-circuit board, ［ 7 ］-press terminal.

The electrical control course of work of the present utility model is such: work as K ₁Close when connecting power supply probe P, P ₁, P ₂Be in the detection wait state, have only the P of working as ₁When there is variable signal in end, IC ₁5 pin just have voltage output, BG ₁Turn-on relay J ₁Adhesive, heater is started working, and circuit ［ 2 ］ is also started working (wherein warning circuit is not worked) simultaneously, makes relay J ₂Adhesive regularly, disconnection, control motor rotation or stop to be pulverized pulping with beans, when soya-bean milk is heated when boiling probe P ₁Vicissitudinous signal makes IC ₁The output of 5 pin no-voltages, heater quits work, and chimes of doom is sent in the warning circuit work in the circuit ［ 2 ］ simultaneously.K ₂Be in normally off at ordinary times, can be used for processing soya-bean milk.When heating up water, burn milk, when making coffee, pressing K ₂, shutoff signal, path makes J ₂Can not adhesive, promptly motor does not turn round.K ₃Be in normally open at ordinary times, when having only as gruel, press it, circuit ［ 3 ］ is started working, and at this moment, heater is regular

Ground work until gruel is carried out, is pressed K again ₁Cut off the electricity supply.Prosecution circuit ［ 1 ］ is by R among Fig. 1 ₁, R ₂, IC ₁, BG ₁, BG ₄Form Deng element.It is different from general liquid level control as seen from the figure, and liquid level is at minimum point P ₂With peak P ₁

Circuit is not all worked, i.e. condition of work P ₂Point position≤liquid level≤P ₁The point position.Work as K ₁After closing, if no liquid in the container, IC ₁6,8 pin be high level, 5,7 pin are low level, heater and motor are not worked, and have realized the self-shield effect, have only when liquid level reach the probe P ₂The time, IC ₁6 pin become low level by high level, make 5 pin output high level, the one tunnel through R ₃Make BG ₁Turn-on relay J ₁The adhesive heater is started working, and when several roads went to circuit ［ 2 ］, ［ 3 ］ when heating soya-bean milk or milk to be boiled in addition, the liquid that boils reached probe P ₁, IC ₁8 pin current potentials reduce that to make 9 pin current potentials be high level, pass through R ₁₃Make BG ₄Conducting, and pin 4 is a low level just, forces 5 pin to become low level by high level, and heater is quit work, simultaneously, warning circuit sends chimes of doom, informs the user, and soya-bean milk or milk are carried out.In fact this circuit can be regarded two controlled phase inverters that self-locking is interconnected as.

Circuit among Fig. 1 ［ 2 ］ is by BG ₃, IC ₁BG ₂Form Electric Machine Control and warning circuit Deng element, effect makes motor turn round according to certain rules.IC ₂Be core parts and R ₇, R ₈, R ₉, D ₄, C ₆Under the effect that discharges and recharges, make IC ₂12 pin compartment of terrains output high level makes J ₂Adhesive or release, wherein BG ₃, R ₄, R ₅, R ₆, C ₄, C ₅, D ₂, form delay circuit.Work as IC ₁When 5 pin are high level, guarantee IC ₂4 pin time-delay a period of time output high level is J during this period of time ₂Adhesive or release make motor rotation or stop, and finish until time-delay and so forth, and just be ground into oar to beans this moment.

Fig. 1 circuit ［ 3 ］ is by K ₃, BG ₅, BG ₆Form delay circuit Deng element, its effect is that control is when pressing K ₃The time, establish 5 pin and be high level, then BG ₅Conducting, and BG ₆End IC so ₁10 pin still are high level.When 5 pin are low level, because D ₆, C ₇, R ₁₁, effect, BG ₅C is worked as in still conducting ₇Discharge finishes, BG ₅End BG ₅Conducting makes IC ₁10 pin are low level, and making 9 pin presets is low level, then BG ₄End, making 4 pin is high level, and at this moment, 5 pin are output as high level again, works as gruel again and reaches P ₁During the position, 9 pin are again high level, directly back and forth carry out, and carry out until meal, press K again ₁Cut off the electricity supply, circuit among Fig. 1 ［ 4 ］ is a power circuit.
