Fuzzy Logic in the washing machine is what? Fuzzy Logic Technology

Choosing a new washing machine, the buyer primarily focuses on the price, size and type of load models. An additional, but very important factor affecting the price and the subsequent comfortable operation of the device is its functionality. "Smart" machines are equipped with many useful functions, the Fuzzy Logic system is included in this list as the main one. What is the use of this technology, and what benefit does it bring to the owner of the machine for washing?

History of the appearance of technology

Technologies Intellowasher and Fuzzy Logic in the washing machine are different names of one control system of the "brain" of the mechanism, which belongs to the company Whirlpool.

But regardless of the brand of the washing device and how its control system is named, the quintessence of this control technology boils down to the notion of "fuzzy logic". It was presented by specialists in the 60s of the 20th century in America and was intended for use in programming on the principle of human thinking.

Fuzzy Logic forms transitional values between constant estimates, such as "short - long," "soft - hard", "cold - hot" and others. This property gave impetus to the beginning of its use as the main principle of household appliances control, such as washing, dishwashing and other devices.

Intelligent machine

Functions Fuzzy Logic - what is this in practice? The system of built-in sensors and sensors, thanks to which the amount of laundry is assessed, the level of pollution of things, water hardness and many other initial parameters. These sensors send information to the microprocessor, which, based on the data obtained, sets the program to a program that takes into account the duration of washing, the degree of heating, the flow rate of the powder, the amount of rinse water, the spinning power, and the operating mode in general.

Fuzzy Logic in the washing machine is a system of built-in sensors that will analyze the level of soiling of laundry, and the microprocessor of the device will calculate the duration of washing. In addition to the level of contamination, touch sensors will help to determine the nature of the contamination, the composition of the fabric and the hardness of the water to choose the optimal, gentle operation.

It can be said that the technology completely manages the washing machine, using several initial parameters. In combination, they make it possible to operate with hundreds of modes (!), This differs machine-machine with Fuzzy Logic from just an automatic device. And between it and the model semi-automatic (low-end washing machine) lies an abyss.

Why is the Fuzzy Logic technology often compared to female logic

To grasp the similarity of the fuzzy logic and behavior of a woman, it is necessary to restore to the smallest detail the process of creating any dish in the kitchen. For example, during the preparation of the test, the former mistress will never take the exact amount of flour at once according to the prescription, because she perfectly understands that the optimum volume depends on many circumstances. A woman will take as much product as needed to get the desired density of the dough, during the batch adding flour several times, if it is necessary to achieve the best result. The same principle is at the top of the Fuzzy Logic function. What is it then, if not female logic?

Strengths and economy

Operation of devices with Fuzzy Logic gives significant advantages:

• Reduction of the duration of washing as a result of an accurate assessment of the level of pollution;
• Decrease in water consumption, due to the preliminary determination of the weight of things and control over foaming;
• Minimum energy consumption due to reduced water volume for heating;
• Full automation of the procedure for washing things, which eliminates the need to manually specify the spin speed, the duration of operation, the number of rinses, the desired water temperature, etc. (for a person, the decision is made by an "intelligent" machine);
• Saving powders, bleaches for laundry and other means that use washing machines.

The feedback from specialists fully confirm the practical benefit and convenience for the operation of devices that have this technology.

Table for calculating the duration of washing

Fuzzy Logic in the washing machine is an opportunity to save electricity and water. The table of the relationship between type and pollution level, which will help to calculate the approximate optimum washing time, is presented below.

Council of specialists. It is important to consider

The main danger for equipment with the Fuzzy Logic mode is the power surges in the network. In our country, it often varies from 160 to 280 volts. Such "jumps" have an extremely negative effect on the electronic "brains" of the mechanism and have sad consequences. The machine starts to malfunction, for example, misses the spin time or ignores the rinse mode. Such failures, when the modes of the washing machine are violated, will inevitably lead to a breakdown, which only a master specialist can correct. To avoid difficulties, it is necessary to connect the machine to the network using a stabilizer.

Overview of budget models

For most LG models, Fuzzy Logic is the underlying technology. For example, LGF1281TD with front loading up to 8 kg, which has 14 programs. This is a budget category, equipped with, nevertheless, the most advanced technologies that meet the proud title of "smart" machines. The price fluctuates around 32 thousand rubles.

The next representative of the popular brand - BOSCH WLG20265OE - is a narrow automatic machine with a drum with a capacity of 5 kg. Additional features: night cycle, special gentle mode for outerwear, the presence of Fuzzy Logic. It is supposed to throw things into the drum during washing. Has protection against leaks and block from children. It costs about 22 thousand rubles.

Samsung WF1802XEC - this is a full-sized unit with the functions implemented in it Eco Bubble plus Fuzzy Logic. The drum holds 8 kg, there are nine programs. An additional bonus is the Eco Drum Clean mode, which allows you to get rid of stale odors without washing in water. The price of the device - from 42 thousand rubles.

INDESIT IWDC 7105 - a copy with special settings for washing delicate fabrics and to eliminate the causes of their creasing. The functional model is reinforced with super-rinsing, fast washing and other modes, including Fuzzy Logic. The cost is approximately 30 thousand rubles.

ELECTROLUX EWT1366HDW - apparatus with a vertical load of 6 kilograms of laundry. Available: seven wash modes, protection from leaks and protection from children. The limiting spin is 1300 revolutions. The price of the device is from 40 thousand rubles.

Excellent results and unprecedented ease of operation combine these washing machines. The experts' opinions confirm the guarantees given by their manufacturers.

Customer Reviews

Washing machines, equipped with an intelligent mode Fuzzy Logic, users gave a very high score. Previously, manufacturing companies tried to add as many modes as possible to the devices. Buyers appreciated it and chose such models, but only, as a rule, rarely used all the proposed functionality. Now the necessary regime carefully chooses the artificial intelligence. Thanks to this, even the previously demanded half drum loading function has lost its relevance. Semi-automatic (washing machine) was previously considered more practical than fully automated models, but now can win positions only in the price category. Customers like the new models:

• Convenience and ease of operation;
• Saving water and energy;
• Speed of washing;
• The ability to stop the program by putting it on pause, and, if necessary, add laundry and change the mode.

It is worth mentioning that the presence of Fuzzy Logic technology in a washing machine is not always a guarantee that absolutely every consumer will be satisfied with the work of his household assistant. On intelligent machines, you can find the following claims from the owners:

• Sophisticated electronic control technology can not be durable;
• Frequent adjustment of the mode during washing changes the device's shutdown time and confuses.

Basically, users are focusing on the positive aspects of the operation of machines with this function. People who have a similar technique at home for a long time argue that it would be difficult for them to abandon the "smart" device. They compare a washing machine without Fuzzy Logic mode with a refrigerator without automatic defrosting.

Conclusion

The system guarantees impeccable quality of washing and rinsing, as well as simplicity and comfort during operation. The price of a washing machine equipped with such a system is, of course, much higher than that of conventional washing machines. Meanwhile, the difference in price pays off after a while due to the practical and economical process of the work of the household device. Technology is a winning alternative to conventional washing machines, equipped with a half load program. It makes it possible to erase a small number of things at no extra cost, saving literally everything. Based on this, it can be argued that it is especially important before buying to make sure that there is an auto weighting program for the selected model. Without it, the Fuzzy Logic system simply can not be, and all assurances in the reverse are nothing more than a marketing move by unscrupulous sellers.
