Description
Technical field
The utility model belongs to the washing machine technical field, more particularly relates to the improvement of the circuit for controlling motor of impeller type washing machine.
Background technology
Impeller type washing machine is in continuous forward and reverse washing process, and because of reversing switch, circuit and motor frequently commutate, constantly surrounding devices, transmission channel or systematic function being constituted the influence that descends is electromagnetic disturbance.Usually this electromagnetic disturbance is referred to as electromagnetic interference.This electromagnetic disturbance is that the frequent commutation by reversing switch, circuit and motor produces, and is the broadband therefore.It is 148.5KHz～30MHz to the conduction continuous disturbance on the power line, penetrates the interrupted harassing and wrecking that then produced 30MHz～300MHz along the power supply wire spoke.What existing delayer was controlled has the contact washing machine because of above-mentioned frequent commutation, there is not corresponding codan again, all do not reach the pertinent regulations of GB4343 " family expenses and similar applications electronic/electric heating appliance/electric tool and similar electric appliance wireless electrical interference characteristic measurement method and permissible value ", can't pass the detection of the Electro Magnetic Compatibility of addressing relevant criterion.
The purpose of this utility model just is to overcome above-mentioned defective, provides a kind of electromagnetic interference of washing machine that makes to reduce greatly, the circuit for controlling motor of the impeller type washing machine that the Electro Magnetic Compatibility of the regulation that is up to state standards requires.
Summary of the invention
In order to achieve the above object, the utility model by the delayed contact K of the timer of the live wire L end that is connected civil power, be connected in parallel on the delayed contact K other end and by two actions of delayed contact K control opposite reversing switch K1 and K2, be connected the single phase capacitor motor on the K1 auxiliary winding, be connected the single phase capacitor motor on the K2 main winding, be connected in parallel on the electric capacity between auxiliary winding and the main winding input, the thermal protector that is connected between auxiliary winding and main winding common port and the civil power ground wire N is constituted.Above-mentioned circuit for controlling motor is also connecting codan.It is a kind of four end resistance-capacitance circuits.Connecting resistance R 2 and the capacitor C 2 of connecting between resistance R 1 and capacitor C 1,4 end and 2 ends of connecting between capacitor C 3,3 ends and 2 ends between its 1 end and 2 ends.Its 1 end is connected with the delayed contact K of circuit for controlling motor, and 2 ends are connected the N end of circuit for controlling motor, and 3 ends are connected the input of the main winding of monophase machine, and 4 ends are connected the input of the auxiliary winding of monophase machine.
The circuit for controlling motor of washing machine is a kind of single phase capacitor motor control circuit.When connecting K, K1, the current phase in the monophase machine auxiliary winding is ahead of the current phase in the main winding, and producing is just changeing magnetic field, and monophase machine is just changeed.Otherwise when connecting K, K2, the current phase in the monophase machine main winding is ahead of the current phase in the auxiliary winding, produces reversing magnetic field, makes the monophase machine counter-rotating.Commutation each time all be a circuit by the change procedure of transient state to stable state, circuit is constantly changing, and also just produces electromagnetic interference constantly.
Behind the codan access control circuit of the present utility model, for the stray electromagnetic interference signal provides a bypass.When frequent commutation, capacitor C 3 and C1 (or C2) have played the effect (the low more capacitive reactance of frequency is big more) of logical high frequency resistance low frequency, have suppressed low-frequency disturbance; Resistance R 1 (or R2) has played the effect (frequency high impedance more is big more) of logical low frequency resistance high frequency, has suppressed High-frequency Interference.Thereby reduced the low-and high-frequency electromagnetic interference of control circuit greatly.Made it to reach the Electro Magnetic Compatibility requirement of standard GB 4343 " family expenses and similar applications electronic/electric heating appliance/electric tool and similar electric appliance wireless electrical interference characteristic measurement method and permissible value " and other correlation standard.
Because R1C1 and R2C2 insert the main winding and auxiliary winding of monophase machine respectively, and the parameter of two windings is identical.So two-way capacitance-resistance series circuit should be identical.That is R1=R2, C1=C2.C3 draws according to practical experience, and C3=(1～3) C1 that is C3=(1～3) C2 are arranged.
Also can resistance R 3 in parallel between 1 end of codan and 2 ends.To adapt to the different requirements of the different voltage civil powers of 220V with 110V.For the civil power of 220V, the value of R3 should be little, with the most of shunting of electric current, protects washing machine to avoid overcurrent.For the civil power of 110V, the value of R3 should be big, and its shunt current is then less.
The purpose of this utility model comes to this and realizes.
The utility model provides a kind of electromagnetic interference of washing machine that makes to reduce greatly, the circuit for controlling motor of the impeller type washing machine that the Electro Magnetic Compatibility of the regulation that makes it to be up to state standards requires.It can be widely used in having in the washing machine of contact of various time-delay controls.
