Classification of washing machines

Classification of washing machinesToday, manufacturers produce various models of washing machines that differ from each other in design, size, set of functions, etc. The classification of machines assumes their grouping according to one or more criteria. The separation will be multi-level.

For example, all machines are designed either for home use or for use in enterprises. At the same time, that household, that industrial washers are divided by type of installation, maximum load, power, functionality. Let's try to deal with the main classification of washing machines according to the first and second criteria.

The first level of classification?

In order to clearly understand what criteria a multi-level grouping of washers is made of, it is necessary to clarify which classification features will be used to separate devices by the first level, the second, etc. Determining selection criteria is a very subjective process. In the presented classification, all automatic washing equipment at the first level is divided into household and industrial machines.

Industrial washers are installed in laundries, at large enterprises, in hotels, and medical institutions. They are designed for daily processing of large quantities of linen and non-stop operation for several hours. Machines of this group are distinguished by high wear resistance, a large permissible load, special washing programs, and a longer service life (with timely maintenance - up to 20-30 years).

Household machines are to be installed in apartments to serve one family. Unlike industrial ones, such machines usually have a richer set of programs, various options and additions. At the same time, “home helpers” are less resistant to wear and tear, their average life is 7–10 years. They are not intended for many hours of continuous operation, for the simultaneous washing of a large mass of things. The body of the CMA is partially made of plastic, the same goes for the tank. Industrial equipment is almost completely made of metal.cars are domestic and industrial

Another sign for dividing by the first level is the type of washing machines. They are divided into activator and drum. Also, the degree of automation of equipment can become a selection criterion, they distinguish here:

  • automatic washers. Equipped with a main electronic module that controls the system. The unit will not only control the amount of water collected, start the main wash, give commands to rinse, spin, drain the waste liquid, but also evaluate the degree of drum loading, the dosage of detergent, independently calculate the optimal amount of water for washing and other characteristics.
  • semi-automatic units. The user is much more often involved in the washing process: you have to pour water to the desired level yourself, at the end of the wash run the spin, then drain the used liquid and fill in a new rinse.

Today, automatic machines have almost replaced semi-automatic equipment. So, semi-automatic machines are now more often found precisely in production than in everyday life.

Second level

What criteria are suitable for classifying washing machines by the second level? Here we will talk about the permissible load volume, dimensions of equipment, methods of installation of devices. Depending on the maximum mass of linen allowed for a one-time washing, machines for home use are divided into three types:

  • with a small load of 2 to 3.5 kg. In most cases, such units are purchased specifically for installation on the wall, under the sink or in a special cabinet. “Babies” can significantly save space, but washing voluminous clothes in them will not work;
  • with an average weight of 4.5 to 7 kg.The most popular and popular models. All global manufacturers, with the exception of US brands, focus on the production of just such units. Machines are able to serve a large family, suitable for washing outerwear, blankets, bedding, soft toys;
  • with a maximum load of over 8 kg. Such equipment can hold up to 14 kg of dry laundry. Automatic machines are notable for their high cost, impressive dimensions and are usually purchased by families, numbering from 6 people.

A similar classification feature can be applied to industrial machines. Depending on the load, machines with an allowable weight of 6.5 to 11 kilograms, 12 to 36 kg, and more than 36 kilograms are allocated. Also, to the second level of grouping, one can apply the division of automata by the depth of the hull.

  1. Super-heavy models have a depth of 33 to 40 cm.
  2. Narrow equipment takes from 40 to 45 cm of space.
  3. Standard cars are more than 45 cm deep.

According to experts, due to the close arrangement of elements in super-heavy and narrow machines, such models will serve much less. However, there are very few practical reasons for confirming such thoughts.

You can also ungroup washing equipment according to other characteristics, for example, the installation method (freestanding, built-in fully or partially), the loading method (front or vertical), etc.

Washing machine efficiency

Outside of the generally accepted classification, one can consider a very interesting feature, which makes it possible to group machines according to the degree of their efficiency. These indicators will be relevant for both home and industrial washing machines. The effectiveness of washing equipment should pay great attention when choosing and buying equipment. These are three main classes:

  • power consumption;
  • washing quality;
  • spin efficiency.

According to the degree of energy saving, washing machines are divided into 5 main groups. The first lines are occupied by the most profitable models belonging to the classes “A ","A + ","A ++ ”, with consumption respectively from 0.17 to 0.19 kW / h, less than 0.17 kW / h, and below 0.15 kW / h. Class “B” includes washing machines that absorb more than 0.19 units of energy, “C” - from 0.23 to 0.27 kilowatts per hour. Higher consumption in modern automatic machines is practically not found.energy classes

The washing efficiency class is assigned to the machine by the manufacturer after comparison with a specific standard. If the device washes off no worse than the standard, “A” class is assigned to it. Next come the groups “B”, “C”, “D”, “E”, “F”. Class "G" speaks of the lowest quality of purification of things.

Differentiation of models according to the degree of extraction efficiency is based on the residual moisture of things pressed at the maximum speed of rotation of the drum. Class “A” indicates that linen is characterized by humidity less than 45%, “B” - from 46 to 54%. The most inefficient class is marked with the letter “E”, things in this case will be quite wet, with a humidity indicator of up to 81%.

Classes "F" and "G", encountered earlier, are not assigned to modern automatic machines.

There are many signs for classifying washing machines. The scope of such work is huge, hundreds of reasons can be found for a multi-level grouping of machines. The basic criteria by which it is easy to classify equipment, we tried to imagine. We hope that the described examples will help you understand the meaning of classification.
