The utility model has the advantages of interference electric pulse elimination, low cost, convenient operation, etc. The utility model is suitable to be popularized and used in washers with two buckets.

Description

Double container washing and extracting machine electricity consumption Magnetic filter

Technical field

The utility model relates to the technical field of motor annex em filtering device on a kind of washing machine.

Background technology

Double container washing and extracting machine is to control the forward or reverse of washing machine motor by the rotating diverter switch, thereby realize the washing process of washing machine, but, motor is turned to switch simultaneously, make the voltage of motor power that fluctuation also take place, can produce more intense electric pulse disturbs, other makes electrical appliance seriously to feed through to family sometimes, operate as normal to them produces interference, seriously some can cause the fault of other household electrical appliances, make them disturbed by serious electric pulse, make circuit be subjected to destroy, cause them not work, influence people's normal life, special China has stipulated that clearly the electromagnetic interference intensity that double container washing and extracting machine produces at work can not surpass certain limits value since carrying out the 3C authentication in May, 2002, otherwise just can not go up market sale, the control motor diverter switch of rotating forward or backwards connects the em filtering device and seems very necessary in double container washing and extracting machine for this reason.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of double container washing and extracting machine electricity consumption Magnetic filter at prior art, it can in time reduce the electric pulse that causes when switch switches and disturb, prevent to cause influence, improve itself property easy for installation and safety in utilization simultaneously other household electrical appliances.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind double container washing and extracting machine electricity consumption Magnetic filter; it is characterized in that by and the filter capacitor that is connected on the control washing machine motor diverter switch of rotating forward or backwards form filter circuit; be assembled in the protective in the apportion sets of elements with filter circuit; from protective, extend many wiring of going to connect diverter switch again, thereby constitute the device that uses separately.

Above-mentioned protective has adopted insulation crust, and insulation crust simultaneously is an opening, be installed in protective in by substrate the electronic component of electric capacity and resistance after, live with resin-sealed, only expose wiring.

Improve again, the line map of filter on its surface printing of above-mentioned insulation crust, mark is gone up the link sign of wiring simultaneously, and wiring just is arranged on this corresponding position.

Compared with prior art; advantage of the present utility model is: be connected to the filter circuit that filter capacitor is formed in parallel on the diverter switch that the control motor rotates forward or backwards in the washing machine; utilize filter circuit to disturb electric pulse to reduce its intensity with causing in the forward and reverse rotation process of motor; avoid interference the operate as normal of other household electrical appliances of electric pulses affect; simultaneously apportion element electric capacity (what have can be with some resistive elements) is concentrated and be assembled in the plastic housing; with resin-sealed; the wiring of only exposing three or four; printing connection line and link on the insulation crust; make the apportion element of filter circuit become a device; improved the convenience of installing and using; do not need respectively electric capacity and be connected on the switch; can put together disposable installation connects; and prevent the destruction that apportion elements such as electric capacity are caused by unexpected factors such as other object strikes or frictions; improved himself protective value; make the safety in utilization of filter better; structure is simple; with low cost; result of use is fine, very is adapted at promoting the use of on the double container washing and extracting machine.
