Fuzzy Logic in the washing machine - pros and cons

Progress is in constant motion, household devices are being improved every day. Machines for washing clothes were not left without attention. The panels of modern units are full of fashionable inscriptions, which we sometimes do not pay attention to. And it is completely in vain, since the functional potential of machines should be used to the fullest. Today we will find out what the Fuzzy Logic sign means in a washing machine. The fact is that the problematic issue associated with maximum energy efficiency was solved in various ways. But the Italian company Zanussi found the best option by developing the fuzzy logic function. The exact translation of these words means “fuzzy logic”, and this is the most successful characteristic in this case.

Principle of operation

Manufacturers believe that the combination of the words “Fuzzy” and “Logic” does not fully reflect the purpose of the program itself, and is only its beautiful name. What is it really?

Washing machines equipped with this function have a large number of built-in touch sensors that can monitor the weight of things loaded into the drum, the level of dirt, the hardness of the water used, etc. Each element transmits a signal to the processor, which, taking into account all the data, sets the time working process, assigns a mode, determines the required amount of liquid.

For example, an infrared sensor monitors the dirtiness of the laundry, and the clearer the water, the cleaner the clothes. Plus, by filling the water with dirt particles, the nature of the contamination is determined, based on the degree of its fat content. The information is transmitted to the microprocessor, which will set the required time for the washing machine to operate.

Modern washing units with the Fuzzy Logic function independently set the consumption of liquids, powders, and spin speed.

Advantages and disadvantages of the function

Taking into account the working principle of this system, the main advantages of the machine can be determined:

• by determining the level of contamination, the time parameter of the work process is reduced;
• the function of weighing loaded laundry allows you to adjust the water flow, which entails saving electrical energy required for heating;
• the process occurs automatically. There is no need to set the spin mode, temperature parameter and other functions manually.

The peculiarity is that washing machines equipped with the fuzzy logic function are much more expensive than other models. But the money spent on their acquisition is fully justified.

As follows from user reviews, the machine also has certain disadvantages:

1. electronic equipment is complex, which reduces the operating life of washing machines.The probability of failures, which is quite natural, increases; repairs are quite expensive;
2. during operation, the machine has the ability to automatically adjust the specified program, which affects the completion of the work;
3. failure of one element of the system has a negative impact on the functionality of the washing machine as a whole;
4. high cost of modern models.

But judging in general, everyone who uses a washing machine with the Fuzzy Logic “smart” system primarily highlights the positive features. True experts assure that the function is a complete electronic management process.

Review of washing machines equipped with Fuzzy Logic technology

This function is found in washing machines from various manufacturers, examples of which are given below:

1. LG F128 TD – a machine that can hold up to eight kilograms of things in its drum, equipped with fourteen programs. In terms of the level of washing and the amount of electrical energy consumed, the machine belongs to the highest class. What makes the model unusual is the presence of a silent operating mode. In addition to the Fuzzy system, there is built-in protection against small children and water leaks. Such a washing mashine costs from 27,000 rubles;
2. Bosch WLG 20265 OE – washing machine, capacity - up to five kilograms. There are unusual programs - washing outerwear, shirts, night mode. It is possible to add things to the drum during the working process, there is protection against water leakage, and a locking device against small children;
3. ASKO W 6884 ECO W – full-sized washing unit, full load is eight kilograms. During push-ups, the machine is capable of delivering up to 1,800 revolutions for one minute.There are twelve programs, but “white underwear” deserves special attention. The unit is equipped with all degrees of protection and is capable of automatically determining the load weight;
4. ELECTROLUX EWT 1366 HDW – a machine into which six kilograms of things are loaded vertically. Seven software, there is protection against children and leaks. Spinning is performed at a speed of 1,300 rpm;
5. SAMSUNG WF 1802 XEC – A full-size washing device that has everything, including Fuzzy Logic and Eco Bubble functions. The drum is designed for eight kilograms, there are nine working programs. Separately, it should be said about Eco Drum Clean, which refreshes laundry from unpleasant odors without washing it.

Tricks of manufacturers

Many companies liked such an unusual name, and they began to use it as marketing advertising, without bothering themselves with unnecessary work on the actual design of such a function.

If you decide to purchase a new washing machine, first of all we recommend studying its functionality, paying attention to the ability to weigh things, determine the type of material, and set the water temperature. When there is nothing like this in the washing mashine, then this is not your option. It can definitely be said that you will not find such logic in cheap washing mashines, even if they have the corresponding inscriptions.

"Women's Thinking"

Many experts compare the new technology with the logical thinking of a woman. What is the reason? The fact is that it is not completely clear how the washing machine will react to certain types of things. The final result depends on the touch sensors and the system responsible for recognizing the data.

Imagine that the program has completed the washing process according to a certain algorithm, but this does not mean that the next time, when loading things in the same volume and degree of contamination, the machine's actions will be repeated. The unit, like a woman, will change its decision, and this is the main relationship.

Conclusion

As follows from customer reviews, there are not so many negative aspects in a washing machine equipped with the Fuzzy Logic system.
