Washing Machine Timer

As time goes on changing, we are becoming dependent on machines, passing the work of our business operations and entering into our domestic life. Even in our domestic life, we do not know how many machines we use, and one of them is the washing machine. That is, it washes clothes like ours and gives us comfort.

Generally, there is no fast deteriorating component in it. But its regulator, which determines how long the machine will last. You may also be facing a similar problem. Today our circuit is a step towards solving this problem. The regulator which did not act properly because of the poor garb will now be replaced by a fully electronic regulator. This circuit belongs to the same regulator and we will learn more about it further.

Internal structure

Below is an internal picture of a normal 6 kg washing machine. The motor which rotates and cleans the clothes has three wires. What we are seeing is that of red (RD), yellow (YL) and white (WH) color. A wire (WH) is connected directly to a wire of electricity and the remaining 2 strings are joined by the timer (once red then once yellow) by the regulator to the other electric wire.

By adding a wire, the machine rotates in the clockwise direction, and by joining the other wire, the machine rotates in the opposite direction of the clock. The Glorious Regulator works with the help of Spring and Garri which alternates the wire to each other. And we do this work here by a relay in our circuit. If there is no rotating or rubbing component in it, then it will last very long.

Working

The circuit above is a timer generating a normal square wave. We will use the prevailing Regulatory Controller 555. This circuit generates a regular square wave whose time range is 5 seconds. That is, for 5 seconds, we get high at Pin number 3 and for the next 5 seconds, we will get the low potential. And when this regulator is giving high potential then the transistor will start and it will also turn on the relay. Thus, the relay will touch a point 5 seconds and touch the second point in the next 5 seconds. And if asked, our washing machine will rotate in the direction of 5 seconds clockwise and the next 5 seconds clock will rotate in the opposite direction.

To give power to this circuit, we have used the linear power source, which is based on transformer and regulator 7812. From this, the circuit will continue to get 12 volts.

Adding the circuit to the washing machine

Now it's time to add the circuit to the washing machine.

Complete the entire circuit and test it in a plastic box. Keep in mind that the box should be completely closed. Do not let the water or the dust go inside.

Now as soon as you remove the current regulator, you will get several colored strings from it.

Remove all those wires from the regulator

Add BK, WH, YL, and RD together by matching the figure number 2 and picture number 3. That is, in Figure 2, add the BK wire to figure number 3 at the BK point. And do so with all the other wires.

After connecting all the points, now close the washing machine and test it.

This regulator will keep turning the washing machine in the direction of the clockwise and in the opposite direction. There is currently no provision to set the time in it. Work is underway to provide time to time and we will publish it as soon as it is completed

Things to note

Never open the washing machine by putting electrical wire

Whenever the washing machine is open from the back, remove the electric wire and under the supervision of an experienced engineer, insert the above-prepared circuit inside the washing machine.

Before applying the washing machine, take the test out of the circuit once

The current carrying load of relay should be at least 15 amps.

When putting a circuit, it is necessary to have full knowledge of security.

Turn the circuit into a compartment that does not contain water, going inside the water can lead to many problems.
