How does a semi-automatic washing machine work?

How does a semi-automatic washing machine work? Semi-automatic machines, despite their lower prevalence, are quite strikingly different from each other in appearance; the choice of models is very rich. But as for the design of semi-automatic washing machines, they are very similar inside. Therefore, using the example of one model, we can demonstrate the content of all the others. Consider a Fairy washing machine with a separate centrifuge and washing tank.

Semi-automatic design

Absolutely all semi-automatic washing machines have the following components:

drive belt system;
housing made of plastic;
an activator that rotates clothes during washing;
mechanical timer.
if there is a spin function, a separate centrifuge.

Since the Fairy is equipped with a spin function, the tank is divided into two compartments: one for washing and rinsing clothes, and the second for spinning. Thus, first the housewife heats the water herself (if the model has a heater, you can pour cold water), then add detergent to it and add dirty laundry.

Attention! Semi-automatic machines, as a rule, have a small load (2-4 kg), but there are also ones with a capacity of 6 kg. It all depends on the size of the tank.

The wash is started by turning the timer knob. There are models with several modes (usually 2-3). For example, standard, gentle wash and quick wash. The main difference between the programs of semi-automatic machines is the cycle duration. After washing, you need to change the water and rinse the laundry. Now you need to transfer the laundry to the centrifuge compartment and turn the timer again to start the spin cycle. The entire wash cycle takes about 20 minutes.

Water is drained through a hose at the bottom of the housing. From the spin compartment, the water either drains into the tray through a special hole, or goes into the washing tank, from where it merges with other water out through the drain hose.

Advantages and disadvantages of semi-automatic machines

No matter how simple or sophisticated the design of a washing machine, pros and cons can be found in both. What are the advantages of semi-automatic machines?

Lightweight, light weight, low price. This is ease of transportation and mobility. The machine can not only be easily moved between rooms, but also transported somewhere far away without any problems, it weighs a little and has acceptable dimensions. A person with any income can buy a semi-automatic machine.
Reliability due to the absence of a complex electronic system and due to a simple mechanism of action.
No problems with connecting to communications, no need for a separate network, soldering into the sewer and connecting to the water supply.
Easy to use and intuitive.
Overall time saving when washing.

However, there are also plenty of shortcomings. Previously, people did not think about them, because they did not see a better alternative, but now these factors can scare off demanding housewives.

Small capacity. While small items can be washed in several passes, large blankets and thick down jackets will have to be washed and wrung out by hand.
Low spin speed. Although some semi-automatic models have decent spin speeds.
Lack of a wide choice of modes and, as a result, the ability to wash capricious fabrics and products.
The drainage system is imperfect. After spinning, the water may be difficult to drain, and a drain hose that comes off at the wrong time can lead to flooding of neighbors.
Unreliable plastic case.

Thus, everyone decides for themselves whether it is more convenient and better for them to use an automatic or a semi-automatic. Both types of washing machines have their own competitive advantages.
