Detailed structure of a Samsung washing machine, description and purpose of components

The structure and equipment of all Samsung washing machines have common features.

The set of structural elements includes both complex electronic modules and sensors, as well as mechanical parts necessary to maintain the smooth operation of the unit.

Knowing the structure of a household appliance allows you to understand the problems that arise and fix them yourself. We will tell you in this article what the structure of a Samsung automatic washing machine is.

How does a Samsung automatic machine work?

Samsung's latest technologies, which are used in the production of automatic washing machines (AWA), make them complex mechanisms. However, upon closer examination, the design of the unit is not difficult to understand.

The body of any model consists of:

• front panel,
• back wall,
• bottom and lid.

1. On the front side there is a control panel, a powder tray, a drain pump, a hose, and a filter.
2. On the top panel there is an inlet valve, a level switch, tank suspensions in the form of springs, and counterweights.
3. On the front side there is a tank and shock absorbers.
4. On the back surface there is a drive belt, motor, pulley, power cord, drain hose.

The internal filling of a technical product includes basic and additional devices. The main ones are:

• control module;
• electric motor;
• tank;
• heating element;
• electric pump

Control module

This unit in the washing appliance is the main electronic part. The control module is a kind of “brain” of the automatic machine, it includes an indicator panel and the software module itself.

The power unit provides power and control of all functions performed. This is possible due to the connection of all sensors, electronics and actuators to the control module. If defects occur in the machine, a signal is sent to the electronic board and reflected on the panel in the form of blinking indicators or a code on the display.

The electronic board is very susceptible to voltage fluctuations, therefore, for flawless operation of the washing machine, you need a device that protects it from power surges.

Motor and tachogenerator

These two important components in a washing machine function in pairs. The electric motor provides the drum rotation specified by the mode.

The commutator-type motor is localized in the lower part of the MCA. It manipulates the drum through a special belt that is attached to the motor shaft and drum pulley. This design leads to periodic wear of the electric brushes and the need for more frequent repairs.

The tachometer monitors the number of revolutions. The tachogenerator sends the result of its tracking to the control module, which checks the speed according to a given program.

Level sensor and filling valve

These details also work in synergy. The purpose of the pressure switch is to control the volume of water poured into the tank. Externally, this element is a round box with wires, fixed under the cover of the machine body.

The level sensor detects the pressure in the tank and sends information to the control module. The latter, upon receiving a sign of a sufficient amount of liquid, sends an order to the filling valve to stop drawing water.

The valve responsible for the flow of water from the water pipe has one, two or three coils. The voltage that is supplied to them after a corresponding signal from the control module causes the membrane in the inlet valve to open. When the voltage drops, the diaphragm valve closes and blocks the flow of water.

Tank and drum

The washing machine tank is a sealed plastic container that is filled with water. Inside it there is a metal drum into which the laundry is placed.

This part of the unit has special devices to improve the quality of washing:

• grooved protrusions;
• plastic rib punches;
• perforations in the walls.

The rotation of the drum is carried out due to a bearing built into the tank and a fixed shaft and transmission pulley.

Heating element and temperature sensor

The heating element (heating element) is located at the bottom of the machine under the tank. This part ensures that the water is heated during washing to a predetermined temperature.The heating element receives a command about the required temperature level from the control module, after which it starts working.

Heating is controlled by a temperature sensor (thermostat or thermistor), which is built into the housing of the heating element. Outwardly, it looks like a metal tube. When the required temperature level is reached, the temperature sensor sends a signal to the control unit, which in turn turns off the heating element.

Gas-filled thermostats are connected via a tube to the control panel temperature sensor. The contacts close as a result of the expansion of heated freon inside the tube.

The second type of temperature sensors is thermistors., work by measuring resistance while heating water. These devices are considered more advanced and reliable. They are used in the assembly of technologically advanced modern Samsung models.

Springs, shock absorbers and counterweights

These design elements are designed to neutralize vibration and “bouncing” of the washing unit during spinning. Vibration dampers consist of a piston and a tube. These parts are attached to the side wall of the housing and the bottom of the tank.

Springs hang from the top and keep the tank suspended. The service life of the bearing and belt depends on the quality and condition of the shock absorbers.

Counterweights (or weights in other words) are concrete or plastic stones located at the bottom of the rear panel of the machine. They keep the tank balanced. Despite their massiveness and integrity, these parts can also be damaged during operation.

The cause of failure is often a crack in the counterweights or loose bolts. In the latter case, the rattling of the device is eliminated by tightening the fasteners.

Locking device and cuff

The mechanism that holds the door closed is essentially an electronic lock. The hatch is first closed mechanically by clicking the lock. After activating the specified program, the door electronically locks, which is accompanied by a soft click.

The hatch locking device guarantees accidental opening of the door during operation of the SMA.. Unlocking occurs after the completion of the program upon receipt of the corresponding command from the control module.

The cuff also plays a protective role against possible leaks through the gap between the hatch door and the tank. Externally, it looks like a rubber seal. This accessory part must always be in satisfactory condition: clean, dry, without cracks or other damage.

Pump, snail, filter

A pump is provided to pump dirty water out of the tank after washing or rinsing. There are two types of application in Samsung washing machines: synchronous and asynchronous.

There are two main elements in the design of any pump:

1. Motor
2. Impeller.

A so-called snail is attached to the top (or front) part of the pump. It is necessary to connect the drain hose.

The same part contains a filter that filters out debris. The pump blades, mounted perpendicularly to its axis, begin to move when the rotor starts.

When waste fluid is discharged, small objects may get into the pump, filter and hose.remaining in clothing (paper clips, coins, buttons). This leads to pump failure and the need for repair.

Hoses, pipes

These parts are designed to fill the tank with water and drain the waste liquid. The length of the hoses depends on the location of the machine and its distance from the sewer and water pipes. If it is necessary to reinstall the machine at a distant distance, use longer tubes.

Hoses are located outside the housing, while pipes are located inside. The inlet and drain pipes work harmoniously and ensure unhindered flow of water.

New hoses and pipes are elastic and flexible. The appearance of cracks, deformations, and drying out threatens leaks, so failed main elements must be replaced in a timely manner.

Powder receiver

The dispenser is a container with different compartments for powder and conditioner. Detergents are loaded into the powder receptacle before starting the program and stored there until the desired washing phase begins.

After the soaking or washing mode is turned on, water enters the compartment with the powder and washes it into the tank. When the final rinse stage is initiated, water is poured through the conditioner compartment.

Conclusion

The design of Samsung washing machines is built from many important parts and components, each of which performs a specific task.

The coordinated work of all components determines the performance of the intended functions and a long service life. Having studied in detail the structure of this household appliance, you can master independent repairs and ensure trouble-free operation.
