Classes of washing machines - learn to understand
Posted by: 21.01.2018
Many people when buying a washing machine in the house are guided when choosing a device such characteristics as the size and type of load. Some pay attention to such important indicators as the quality of washing, energy consumption and spin class. It is the last three properties that need to be considered more carefully, since everything is not as simple with them as it may seem at first glance. It is time to find out the answers to the questions about what different washing classes are of, what washing class is better in a washing machine, and how certain device characteristics depend on the class name? Now find out!
Class of washing
The washing class is the most important parameter that should be repelled when choosing a washing machine. This indicator indicates the effectiveness of removing stains from various tissues. Of course, this is not an absolute value, because on the same washing machine, even with the upper class, different stains will be washed off with different success - this will be affected by the powder used for washing, and water hardness, and other indicators. That is why the washing class is assigned only after special testing under the same conditions - 60 minutes of washing in water with a temperature of 60 degrees on the same fabric with equal stains. According to the results of the comparison of the washed fabric with the washed one in the reference machine a class is assigned.
What is a washing machine washing class, we have already figured out, but what exactly does it affect and how is it determined? The following visual table with all classes of washing will help to understand this:
|Efficiency||1,3||1-1,29||От 0,97||0,94-0,97||0,91-0,94||0,88-0,91||Until 0,88|
What is washing class A? By this index is meant the highest assessment of the effectiveness of washing in a particular device. The further the alphabet, the worse the performance. Accordingly, the washing class G is the worst. It should be remembered that a car with a higher class of washing will not always cost more than others - devices with poorer indicators may cost more due to brand awareness and other factors. That is why the cost almost does not solve.
What is the best washing class? Of course, the one that is as high as possible is the rest - A. Class B is also practically not inferior in efficiency, while the others are no longer so good.
On the washing machine several different classes may be indicated, and it is not necessary that this is the washing class of the washing machines, because there are other parameters. For example, spin class. It characterizes the percentage of moisture of the laundry, which remains after washing with a spin. This indicator is completely dependent on the number of revolutions per second - the higher the speed, the better the spin cycle and the lower the humidity after washing. Like the washing class, the spin class (which you already know) is classified by indices from A to G. Here is a detailed class table:
|A||Until 45||Extremely strong|
|G||90 and above||Very weak|
The most effective spinning occurs at 1500 revolutions per second, while the weakest becomes due to such a low drum speed as 400 per minute or even less.
Inquiring about what a washing class and spin class are, remember that it is not always the highest spin class that can be justified - sometimes high revolutions lead to twisting and deformation of tissue structures. Machines with spin class A are suitable for washing items of coarse and thick fabric. Washing machines with a spin class F and G are designed for washing delicate and very thin fabrics, and therefore are also in high demand.
Before 2002, energy consumption classes also had 7 of different indexes from A to G, but after this date the most economical class A + was introduced by manufacturers of washing machines, which became the eighth, but the most profitable. To calculate the energy class of machines applied testing for 60 minutes at a temperature of 60 degrees. The energy expended on this washing is laid down in the basis for assigning a certain class to a washing machine:
|Class||Characterization||Electricity consumption (kW * h / kg)|
|A+||Most economical||Until 0,17|
|G||Extremely tall||0,40 and more|
It should be remembered that the values of the energy class, which is indicated on the body of the washing machine, are indicated for one kilogram of laundry to be washed. Therefore, in order to most accurately calculate the flow rate, it is necessary to multiply the flow rate for washing one kilogram by the mass of laundry to be washed. Also, the consumption will depend on the washing time and the selected mode.
Today, modern washing machines are constantly being improved, so it is increasingly possible to meet devices with the A + wash class. Classes such as A, B and C can also be found, but not often anymore. Lower classes among modern units are almost impossible to meet - they are not very popular among users.
Now you know what a washing class in a washing machine means, what kind of spin and power consumption there are. Having seen the lettering on the body of your typewriter, you will not fall into a stupor and not lose your head, but you will immediately understand what to expect from your equipment. When buying a washing machine, pay attention to all three specified classes - it is better to choose the highest washing class and energy consumption, and the spin class - depending on what things you are going to wash. For coarse fabrics - the highest, for delicate - the lower classes of extraction.
