Buying a washing machine is a responsible business. Clean, fresh linen has always been an indicator of good taste, prosperity. If before, linen often had to be washed by hand, now this duty lies on the washing machine. Choosing a washing machine, everyone looks at a number of qualities that will satisfy the needs of the family and save the budget. To the consumer was easier to navigate the market, the classification of washing machines was introduced.
Washing machines are divided into 7 main classes: A, B, C, D, E, F and G.
Accordingly, the higher the class, the better the machine will erase the .But the cost of the highest-class car will not always be higher: often the price is too high due to the advertised brand.
Classes F and G are extremely rare, and they should not be taken. Because the efficiency of washing in such machines is small. And cars of higher class are not much more expensive, but their efficiency will be higher in a few times.
Classification of washing machines
| Classes | Washing | Quality indicator |
|
| Excellent | 1,3 |
|
| Very good | 1-1,3 |
| With | Good | 0.97-1 |
| D | Normal | 0.94-0.97 |
| E | Satisfactory | 0,91-0,94 |
| F | Bad | 0,88-0,91 |
| G | Very bad | 0,88-0 |
Assign classes to washing machines for a reason. After all, stains on clothing can be of different origins, with one type of cloth the stain will go well, but the other does not. Therefore, it is customary to carry out tests to assign classes to washing machines.
The test compares the quality of washing in the washing machine under test with washing in a reference machine. One and the same fabric with the same dirt is immersed in washing machines. Washing lasts 1 hour at a temperature of 60 C. For washing the same detergent is used. After washing, the fabrics are compared with a special automatic machine. The machine is used to avoid the influence of the human factor. Based on the results of washing machines, a class will be assigned. The unit of measuring the quality of washing is the efficiency index, which corresponds to its class.
Reference machine
In 1995 there was the very first washing machine-standard. Now such machines are made only by authorized manufacturers. These machines, no doubt, are effective. But progress is moving forward - now you can buy a washing machine, which in its performance will be better than the reference one.
The reference washing machine should not show the best result, but a stable one. The unique low variation of the indicators and makes it a benchmark for other washing machines.
Washing class of washing machine
To determine the washing class of the washing machine, tests are also carried out. During the test, the laundry is weighed dry and after washing. The smaller the difference between the two, the better the washing machine will press the laundry.
The following factors affect the spinning quality:
- drum diameter;
- number of turns of the washing machine;
- full cycle time;
- is a type of pressed fabric.
It is worth noting that a high class of pressing is not always profitable. The more speed the machine makes, the more traumatized the fabric is when it is squeezed. This should be taken into account when buying, especially if there are a lot of silk, knitted things, clothes from delicate fabrics in the wardrobe.
Energy class
At this rate, consumers look even more often than on the efficiency index of the washing machine. On average, in a family washing machine works up to 5-6 hours a week. In a month it leaves about 20 hours. And the cost of electricity, of course, everyone wants to reduce.
Lately, manufacturers are paying much attention to this indicator. And if before washing machines for energy costs were classified into seven groups, then in 2002 they started producing A + cars. This is the most economical option, which consumes 0.17 kWh / kg.
To assign a power consumption class to the washing machine, tests are carried out. In washing machines load 1 kg of cotton underwear. The laundry is washed for 1 hour at a temperature of 60 ° C. At the end of the wash, the amount of energy consumed is counted. It is depending on this indicator that the machine will be assigned a power consumption class.
Every year manufacturers come up with something new to reduce the cost of customers for electricity. And except for machines of a class of power consumption A +, already there are automatic machines A ++ and A? +++.These washing machines can reduce power consumption by 10, 20, and even 30%.
What should I look for when buying?
The highest class of washing corresponds to the most qualitative work of the washing machine .Although the difference between the class of washing A and B visually you can hardly notice - so it will be insignificant. But the machines, the washing class of which is lower than C is not worth buying. Savings will be minimal, but on quality it will be reflected.
If we talk about spinning classes, then quite a machine of class C is enough. It squeezes well, the laundry will dry quickly enough on the rope after spinning. Machines with a speed of more than 1200 are often displaced during the spin, jumping and vibrating. To avoid this, you have to buy special legs or put some material.
All the necessary information on the classification of the washing machine can be found on its housing. All cars now have factory stickers, on which it is written, to which class it belongs. If there are no grades on the machine, do not worry. This means that the machine is not intended for sale in the EU countries. Possessing information, you can independently assign a class to the washing machine, looking in its technical characteristics.
