The design of the washing machine Indesit

Since almost all models of front-loading washing machines are almost identical, we will consider the internal structure of the washing machine using the Indesit brand unit as an example. Since he is today a leader in production and sales in the Russian market. So, we illustrate the device of the Indesit washing machine.

We list the main elements

The device of the washing machine includes both basic and additional modules. Your unit will only work if all components are in smooth contact with each other. In the car of any model there are:

• electric motor;
• tank and drum;
• pump for draining;
• control panel with electric module support;
• spring shock absorbers;
• special assembly with bearings;
• the main body, the rear wall of which is made in the form of a manhole cover;
• valve for fluid collection;
• tubular electric heater and parts for it.

We draw your attention to the fact that this is a completely basic set of parts for any washing device. If you figure out what and how the layout works, then you can easily analyze the behavior of your Indesit washing machine.

How does the technique work?

The Indesit washing machine is equipped with a plastic tank. In order to avoid deformation of the tank, it is not connected so tightly to the body that excessive vibrations are not created that destroy the tank. After all, the tank moves very actively during washing and, especially, the spin cycle, and the body remains motionless, which in fact ensures the safety of the tank. In addition to this, two shock absorbers are placed to support the bottom, and springs are located on top.

During washing, the drum rotates due to the special pulley with which it is connected via a cross. The pulley, in turn, receives revolutions transmitted by an electric motor through a belt drive. All these actions make the pulley rotate, and since it is fastened to the drum, the drum also rotates, due to which our things are washed. The drum itself is built into the tank with a mount.

The so-called “center of intelligence” of the washing machine is the control board, it is it that sets the sequence of operations and the coordinated interaction of all components of the unit. So, for example, supplying the washing machine with water includes a number of actions of different parts: the inlet valve collects water from the water supply, the heater heats it to the required temperature, the pressure switch controls the volume of water, and a special pump removes contaminated water after the washing process is completed.

Now you can roughly imagine how your washing machine works and how, but to add details, you should take a look at the operation of each module separately.

Main capacity and drum

The drums are predominantly made of stainless steel, as are the tanks of some washing machines. This material is more durable and, as a result, your machine will last much longer. However, if you prefer a more budgetary and easier option, take a machine with a plastic tank. It is not so durable, but it is cheaper and easier to carry. In the most common models, the tank is located horizontally, although some manufacturers produce machines with inclined tanks.

All modern Indesit washing machines are equipped with plastic tanks.

So, the tank is the main capacity of any washing machine. As we already understood, a drum is built in there, into which you load your laundry. The drum usually has a huge number of holes through which water from the tank enters this container. Yes, water is drawn from the water supply into the tank, there it is heated and mixed with powder, and it enters the drum during the washing process. In addition, the surface of the metal tank is very corrugated, which improves the quality of the wash.In order to avoid leaks and other troubles, no foreign objects should enter the tank.

Heated mixture of water and powder

A tubular electric heater is responsible for heating the water in the tank, and in short - a heater, which is built into the bottom of the machine. With the active use of the washing machine, the heater is subjected to the greatest damage, because scum forms on its surface, gradually putting it out of order, and, in addition, heating elements always fail faster than other electrical appliances. The more often you wash in hot water, the faster the heater will have problems.

According to the technical characteristics, it is worth saying that the energy consumption is approximately 1800-2200 watts. This is equal to the average energy consumed by any heating mechanism. Therefore, if it seems to you that the washer “eats” a lot of energy, then the point is clearly in the heater.

What sets the drum in motion?

Remember, we already talked about the connection of the drum, pulley and electric motor? It is the electric motor that drives the device. Indesit uses collector motors in order to save money and, as a result, to reduce the cost of goods. However, collector motors do not have any enviable strength, and in addition, they are very susceptible to voltage drops, so it is better to connect them through a stabilizer.

Collector motors quickly lose their level of functionality, and eventually cease to work if they are not carefully monitored (you will have to, for example, change brushes regularly).

Water supply and removal

Water is supplied from the water supply system to the tank according to this scheme.

1. The specialized module “orders” the inlet valve to open;
2. The valve opens, and since it is under high pressure, water immediately begins to penetrate into the tank.
3. The pressure switch controls the volume of water so that it gets exactly as much as needed (the same thing happens when draining the water, so this sensor is indispensable for any machine);
4. When the required volume is reached, the pressure switch signals the module, and that, in turn, signals to the valve that there is enough water and needs to be closed.
5. The valve closes and the water supply stops.

Once the wash is completed, the control module begins to interact with the pump. The pump receives a signal to drain the water and begins to push it into the sewer through the drain hose. Thus, water is pumped out of the tank. Then, using the same operations, the machine draws water in order to rinse the laundry, and then it drains it the same way.

"Brain" washing

The control board is responsible for all the details of the machine, except for the control panel (it includes all buttons, indicators, etc.). There is a separate fee for this. Both of these devices are combined and perform the “intelligence” function of the machine: they issue commands to the modules for coordinated operation of the device.

Programs and washing modes are pre-thought out algorithms of certain actions that are recorded on the control board. Accordingly, she is responsible for the work of any program that you choose. The device board consists of many semiconductor elements (these include triacs, thyristors and other details).

Contacts between the parts are carried out by means of special electrically conductive tracks, which are also located on the control board.

The control panel board has a slightly different purpose. While the control board coordinates the interaction of parts, this one coordinates the interaction of the operator and the control board. That is, its task is to “explain” to the control board what exactly the user wants to do, and also to inform him about all the details of the wash (by displaying information on a special screen or through indicators).

Auxiliary elements

We have figured out how the basic parts of the Indesit washing machine work. However, there are many more.Their role is not so fundamental, but without them your washing will also not take place. Here is a list of them.

1. Parts that prevent the harmful effects of vibration on the tank - springs and shock absorbers. They muffle the vibration.
2. To prevent water from flowing out from under the manhole cover, there is a special cuff. This is a kind of rubber seal, which tightly seals the hatch during washing.
3. Hatch lock device - abbreviated as UBL. This part also contributes to the complete closure of the hatch and the prevention of its accidental or independent opening. As long as the UBL is in good condition, water will not spill out of the machine.
4. Drive belt. The one that directs revolutions to the pulley, and the pulley, as you remember, helps to rotate the drum. Therefore, to work the drum can not do without this detail.
5. Counterweights. Counterweights are very large in volume and weight, stones that are installed inside the case, increasing its weight. Due to these details, the machine during spinning has the ability to resist centrifugal force. Otherwise, the washing machine would very actively move around the room due to pressure on the side walls.
6. Hatch door. There is no need to describe the significance of this detail. Without it, washing is basically impossible.
7. Powder collector. There you put detergent and conditioner, which are metered into the tank during the washing process. As a rule, it includes three compartments for different types of detergents.
8. Branch pipes. Through them, water flows into and out of the tank. Built into the case.

Now, knowing all the details of the operation of the Indesit washing machine and the features of its design, you can easily analyze its behavior and condition. If a problem arises, you will know what you should pay attention to first of all, and you will also probably be able to carry out a simple repair yourself. Remember that with a careful attitude, your device will last you much longer and will delight you with its quality much more.
