The washing machine was invented more than 200 years ago and since then is an indispensable attribute of our daily life. Today, the market offers three types of models, which can be classified as fully automatic, semi-automatic and ultrasonic devices.
Of course, the features of each type affect the choice of the optimal model when buying a washer.
Fully automatic washer
Today, these models are most common. They are fully controlled by software and provide a very good functionality. Simple inexpensive models use preset washing programs. But more complex and expensive washers have an enhanced functionality that includes automatic adjustment of the amount of water and detergents, water temperature, drum speed, etc. Modern models are equipped with a steel or plastic drum for laundry.
Semi automatic models
Semi automatic devices have only timer. Additional controls are absent. The working mechanism of the device is made as an activator that is a tank with the motor. The motor shaft is equipped with the special blades that twist and stirred the linen in drum. The foam amount during washing is very little, therefore, these devices can use the detergents for hand washing.
Models with activators were very common a few decades ago. Today, such models are almost universally removed from production. However, some manufacturers continue to produce small batches of these devices. Small dimensions, low weight and price are the main advantages of such models. Additionally, they do not require connection to the water supply and sewerage.
Semi-automatic models provide washing from 3,3 to 15 lb of dry laundry. Choosing programs for washing is absent, operating speed is small enough, the cold water does not heated. Drain of dirty water is carried out with the help of drain hose.
These models are ideal for washing a small laundry amount, for example, in a country house.
Portable ultrasonic washing machine
Interestingly, manufacturers initially positioned these small devices as an ordinary concussor. Subsequently, this device was slightly modified and today it’s known as ultrasonic washing machine.
These models contain a small circuit board inside the plastic or metal housing that generates the ultrasonic signal with a frequency of 22-30 kHz. This signal provides vibration that increases the efficiency of dissolving dirt on the laundry. When washing, the device is placed in a container with linen and water. Cycle washing time is approximately 1 hour.
Pros & cons of ultrasonic models
PROS:
– Compact.
Of course, the compactness is a major advantage compared to traditional washing machines. Ultrasonic machines are much smaller and lighter even compared to compact washing machines.
– Very low price.
For example, the cost of many ultrasonic devices is only a few tens of dollars. Even spare parts for washing machine are significantly more expensive.
– Very low power consumption.
The amount of electricity for a single wash cycle of automatic model corresponds to energy consumption of approximately 300 full cycles of this device.
– Reliability.
Design of these devices is very simple. Therefore, they practically do not break down. This device can operate successfully without failure for decades.
CONS:
– Washing quality is low.
The wash quality with the help of these devices is not much superior the traditional soaking with the help of a good washing powder.
However, some users suggest methods for getting the maximum quality level.
This device is much better to wash clothes if the container with water and linen is covered with a lid. Washing clothes is more effective in metal containers. The water temperature should be at least 50 degrees. The result also depends on the load density of the laundry. A small amount of laundry in a large enough container is washed better. The stirring also increases the washing quality. Powder for hand washing must be of sufficiently high quality.
– Automatic rinsing and spin are absent.
These functions are performed manually.
