The structure of an automatic washing machine

Many of us depend on the modern marvel that is the automatic washing machine on a daily basis, but few of us truly know how it operates. With just a button push, it takes a load of filthy clothes, spins them around, and returns them fresh and clean. However, what’s going on within that metal box to cause this magic to occur?

To put it simply, an automatic washing machine consists of a number of parts that combine to clean your clothes.

Main parts

A description of an automatic washing machine’s components should open a story about its assembly. The primary internal components and their locations are shown in the diagram below. The machine might also have other parts in addition to them, like different sensors, relays, etc.

This is a schematic illustration of a washing machine’s construction.

The following are a washing machine’s main parts:

  • body (panels, top cover and hatch door);
  • control panel and electronic module;
  • tank and drum;
  • engine;
  • tubular electric heater (TEN);
  • water intake system (valve, water level sensor, etc.);
  • water drainage system (drain pump, filter, etc.);
  • balancing system (springs, shock absorbers).

Extra units can be single sensors, like a laundry moisture level sensor in units with a drying function, or complete systems, like a leak prevention system.

We will provide you with more information about the major units.

Body and its elements

The front, rear, and two side panels, along with the top cover, make up the washing machine’s body. The front portion is equipped with a rubber cuff, a lock mechanism, and a hatch door. Occasionally, the door has a tiny window that opens independently, allowing you to add items to the washing machine’s drum while it’s being washed.

Certain washing machine models have a small window in the hatch door that allows you to add items while the machine is washing.

The purpose of the rubber cuff is to prevent water leaks and guarantee a tight door fit. When the washing program is activated, the hatch is locked thanks to a lock mechanism that is connected to the control module. The drain filter is situated behind a door at the base of the front panel.

Although most washing machine models have a single back panel, some models allow you to remove the back wall in separate pieces.

Control panel and electronic module

The washing machine’s "brain" is the electronic module, and its "face" is the control panel. Levers and buttons on the panel let you start the machine, choose your preferred washing mode, and keep an eye on its progress. The majority of contemporary models have a liquid crystal display that shows all the pertinent data, including how many minutes remain in the cycle and whether the hatch lock is engaged. Information codes are also displayed in the event of a malfunction, allowing you to identify the type of issue.

You can choose the washing mode, turn on the machine, and keep an eye on its progress using the dashboard.

Directly beneath the panel is the electronic module, which commands and regulates the operation of every unit in the unit. The equipment’s wash programs and functions are stored in the memory of the module. The board requires information from various machine components in order to function properly, and it receives this information via sensor signals (tacho sensor, thermostat, etc.).

The washing machine’s control module is seen in the picture.

Particularly vulnerable to voltage surges are the unit’s electronic components, including the control module.

Tank and drum

A plastic container with a drum inside is called a tank. They take up the majority of the case’s interior when combined. The washing machine drum has a fairly straightforward construction: it is composed of metal and has holes in its surface where water flows through while the machine is being washed.

The picture shows the drum-filled washing machine tank.

Torque is transferred to the drum by a bearing unit, which is mounted inside the drum and serves as a connecting element between the shaft, pulley, and motor. The unit’s performance determines how smoothly the part rotates during washing. It is made up of two bearings and a rubber seal. Avoid piling too much laundry in the washing machine drum to prolong the unit’s lifespan.

The bearing unit’s location is indicated by the arrow in the picture.

Engine

The washing machine drum’s rotation is guaranteed by the electric motor. Beneath the tank is a belt-driven motor whose shaft is belted to a pulley, which is a wheel fastened to the drum shaft. This design uses multiple parts to transfer torque from the engine to the drum.

The image displays a motor with a belt drive device.

When a unit is outfitted with a direct drive, the torque is transferred directly from the motor, which is situated on the tank. There are very few connecting links between the motor and the drum.

An inverter motor with a direct drive is seen in the picture.

Ten

The water must be heated to the appropriate temperature for washing by the tubular electric heater. This is actually a bent metal tube that gives the water thermal energy when heated. Usually, the component is mounted beneath the drum in the tank’s lower section. A unique type of sensor called a thermostat regulates the water’s temperature.

Ten are placed beneath the drum in the washing machine’s tank.

The heater needs to be cleaned on a regular basis to prevent failure because of the lime coating that forms over time from continuous contact with hard water.

Water supply system

An intake valve, an input filter, and nozzles link the detergent compartment to the water supply hose and tank in the water collection system. The inlet filter, which is placed where the water supply hose connects to the washing machine, collects large particles that may enter the unit from the water supply. Usually, it’s a tiny, spherical mesh composed of metal or plastic.

The inlet valve controls the water supply.

When the pressure switch, also known as the water level sensor, signals the control module to fill the tank to the necessary level, the inlet valve both ensures that water is supplied to the detergent tray and the tank, and it also cuts off the water supply.

Water drainage system

The pump is the primary component of the water drainage system. The component is made up of an electric motor with a cross impeller on one side and a snail with a filter on the other. The pump starts to pump water out of the tank and discharge it into the sewer via the drain hose when the control module sends a signal to the pump.

This is a schematic illustration of the washing machine’s construction.

The filter keeps debris away from the pump’s components. Periodically, it must be cleaned by taking it out through the front panel of the case’s door.

Balancing system

Because of their weight and volume, the tank and drum vibrate a lot while being washed. Concrete blocks that are fastened to the top and bottom of the tank make up the counterweight system that is incorporated into the machine body to balance the vibration that occurs.

When the washing machine is operating, counterweights help to reduce vibrations.

To further reduce vibrations during the washing process, the tank is suspended from above on specially designed springs and placed on shock absorbers.

Let’s now examine the washing machine’s general operating principle.

An automatic washing machine is a sophisticated yet simple device that streamlines laundry by mechanizing the washing process. The machine’s main components are a pump that removes water, a motor that spins the drum to clean the clothes, a control system that oversees the washing cycles. Users can choose the best machine for their needs and perform informed maintenance and troubleshooting by having a basic understanding of these components.

Principle of operation

Getting water from the water supply is the first step in washing. Water enters the detergent tray and the tank when the electronic module signals the inlet valve to open. The pressure switch keeps track of the tank’s filling and, when it reaches a certain level, signals the module accordingly, closing the valve. After that, the heating element activates and raises the water’s temperature to the level specified by the program.

The drum rotates (changing direction and speed) while being washed. Through the holes in the tank, water containing dissolved detergent flows, mixing the laundry and rubbing it against the drum’s corrugated surface to gradually clean it. Centrifugal force aids in the removal of the majority of the moisture from the laundry as rotation happens at maximum speed during the spin cycle. A pump is used to transfer waste water from the tank into the sewer.

The majority of automatic washers function according to a general

The fundamental idea behind how any conventional automatic washing machine works is this. The extra choices and systems account for the differences. Units featuring a drying feature, for instance, have a separate heating element that warms the air and a unique fan that forces the heated air into the drum. Following the primary washing mode, the items are dried by removing the remaining liquid through condensation and hot air pressure.

A device is positioned between the washing machine tank and the dispenser pipe in units equipped with the Eco Bubble feature. The water and powder mixture foams as it passes through it, resulting in more effective washing.

The fundamental idea of washing has numerous extensions. It is worthwhile to focus on the vertical loading washing machine separately.

Features of units with vertical loading

The majority of components found in front-loading washing machines are also found in vertically loaded models, including the motor, shock absorbers, drum, tank, and so on.

Certain design elements are present in washing machines with vertical loading.

These types of units have a hinged lid on the body that is used to load laundry. The drum has flaps and is supported by two bearing assemblies. A self-positioning sensor is installed in many units to guarantee that the flaps stop exactly in front of the top cover. Usually found on the far side of the upper body, is the control panel.

Since the tank and drum’s top-hole design virtually eliminates water leakage through the lid, many units of this type do not have a rubber sealing cuff. For the same reason, you can typically add laundry that has been forgotten to such a machine and let it run through the whole washing cycle.

We hope that this post will provide you with additional knowledge about your home assistant.
