The multipurpose controller

The utility model relates to a kind of multipurpose controller, in particular for the timing of household electrical appliance, and the controller of temperature control or speed governing.

At present used controller is generally all by regularly controlling household electrical appliance is converted to halted state from operating state; but people usually wish also that electrical equipment can change between two operating states of large and small power in actual applications; can change between small-power discontinuous operation state and halted state, general controller but is difficult to realize this two functions.

The purpose of this utility model is to overcome the deficiency of prior art and a kind of multipurpose controller is provided for this reason, when it makes high-power timing controlled, can be automatically brought to small-power pulse control after being timed to, and when doing small-power pulse control, stops automatically after being timed to

The technical scheme that realizes the utility model purpose is a kind of multipurpose controller, controller in particular for timing, temperature control or the speed governing of household electrical appliance, comprise for the supply socket that patches household electrical appliance, its special character is the relay that has a control socket and power supply to open by on-off, one for control circuit provides the regulator rectifier circuit of D.C. regulated power supply, one by the silicon controlled conducting or end to come the timing circuit of control relay on off state and one be timed to the low-frequency oscillatory network that the back automatic control relay is in the discontinuous operation state.

And, voltage-stabiliser tube V ₂With capacitor C ₁Back in parallel and resistance R ₁And diode V ₁Be serially connected with on the power supply, form stable DC voltage between A, B point, timing circuit is by potentiometer RP ₁, capacitor C ₂And the D in six Schmidt triggers ₁Constitute RP ₁With C ₂Be serially connected with between A, the B point RP ₁Sliding contact also with D ₁Input link to each other, between B, M point, be provided with selector switch S ₁

And, potentiometer RP ₂, capacitor C ₃, C ₄, the D in six Schmidt triggers ₂, D ₃, D ₄And diode V ₇, V ₈Form the low-frequency pulse oscillating circuit, RP ₂With C ₃Be serially connected with between A, the B point D ₂, V ₇, R ₄, D ₃, D ₄, V ₈Series connection forms loop and RP successively ₂Sliding contact connect C ₄, R ₅Be connected to after the parallel connection between B, the N point.

And, D ₁, D ₂Output respectively through diode V ₄, V ₅With coupled switch S ₂A ₁, a ₂Point links to each other, through V ₃, V ₆With S ₂B ₁, b ₂Point links to each other, the D of six Schmidt triggers ₅, D ₆Back in parallel and resistance R ₇, light-emitting diode V ₉Be serially connected with switch S ₂And bidirectional triode thyristor V ₁₀G end between, V ₁₀T ₁Be terminated at the A point, I ₂End then links to each other with relay.

By the technical scheme break-make of this controller by the bidirectional triode thyristor control relay as can be known, be provided with timing circuit and small-power pulse oscillation circuit, selector switch S ₁When the continuous operation position, timing circuit is inoperative, and electrical equipment maintenance high power CW work or small-power intermittent duty are constant, S ₁When the timing working position (overhead positions), if selector switch S ₂Be in the continuous control position (promptly and a ₁, a ₂Connect), D then ₁The high potential of output makes the controllable silicon conducting, and electrical equipment at first is in the high power work state, and after regularly finishing, the silicon controlled conducting only is subjected to D with shutoff ₂The control of output current potential, electrical equipment just are transformed into small-power discontinuous operation state, work as S ₂Be in the pulse control position, electrical equipment then at first is in small-power discontinuous operation state, regularly finishes back electrical equipment and quits work, and electrical equipment has just been realized the conversion of large and small power conversion of operation state and small-power discontinuous operation state and halted state like this.

The utility model is described in further detail below with reference to accompanying drawing.

Accompanying drawing is a circuit diagram of the present utility model.

Shown in accompanying drawing, controller provided by the utility model is by one six Schmidt trigger and diode, bidirectional triode thyristor, and elements such as relay are formed, and hand over source current through diode V ₁Rectification, resistance R ₁The current limliting step-down is at voltage-stabiliser tube V ₂Two ends form D.C. regulated power supply, potentiometer RP ₁, capacitor C ₂, trigger D ₁ Form timing circuit 1, selector switch S Deng element ₁When being in timing position, DC power supply is through R ₂, RP ₁To C ₂C is worked as in charging ₂Voltage less than D ₁Trigger voltage the time, D ₁Output is a high potential, through V ₄, S ₂Be added to D ₅, D ₆The input end, make D ₅, D ₆Output is " 0 ", bidirectional triode thyristor V ₁₀The G utmost point flow through direct current, controllable silicon conducting, the normally opened contact closure of relay K, light-emitting diode V ₉Luminous, expression is by socket X ₁, X ₂The household electric appliance operation of power supply is worked as C ₂On voltage be raised to D ₁Trigger voltage the time, D ₁Output become electronegative potential, D ₅, D ₆Output be high potential then, controllable silicon ends, V ₉Unglazed, timing arrives, by changing potentiometer RP ₁Adjustable the adjusting of resistance the time time length, if switch S ₁Be in the continuous operation position, then timing circuit is inoperative, can keep high power CW work or small-power discontinuous operation state constant
