Drum volume
The internal volume of the dryer drum.
A
larger drum can accommodate more laundry, but there is no rigid dependence here: models with the same volume may differ in maximum load. It is because to process a large mass of laundry, one need not only a capacious drum but also an engine of appropriate power. At the same time, in a larger drum, the same mass of laundry will dry more efficiently than in a small one, because laundry will be more freely distributed over the drum, crumpled less, and warm air will better penetrate the folds of the fabric. As a result, for the same drum volume, a model with a smaller load will be more efficient and performant than a model with a larger load. On the other hand, a volumetric drum takes up more space and the dimensions of the dryer are largely determined by the dimensions of the drum.
Drying basket
The presence
of a drying basket allows you to carefully place woollen items, as well as shoes, which contributes to delicate drying and the laundry does not “fly” around the drum like in washing machines.
Drum lighting
Lighting system for the internal volume of the device. It usually turns on automatically when the dryer door is opened - thus reducing the likelihood that some items (especially small and dark ones) will be forgotten in the drum.
Self-cleaning heat exchanger
System
for automatic cleaning of the heat exchanger from fibres and all kinds of deposits that prevent easy air circulation. The self-cleaning function is performed during each drying cycle. It extends the life span of the heat exchanger and ensures consistently low energy consumption over the life span of the dryer.
Self-cleaning door filter
Rinsing the door filter on board the dryer with water after each drying cycle. The
self-cleaning door filter eliminates the need to manually clean the filter by removing it from the dryer.
Drying class
Drying class describes the overall drying efficiency that the machine provides. It is denoted by a Latin letter, where A is the best efficiency, and further in decreasing order (
drying class B is inferior to
class A, but exceeds
class C). Naturally, higher efficiency machines cost more (ceteris paribus).
Energy class
The energy consumption class shows not the actual energy consumption but the efficiency of the dryer. In other words, what part of the electricity consumed goes directly to useful work. For dryers, this parameter is especially important because such devices have high electricity consumption. As a result, models with the same capabilities but different energy efficiency classes differ markedly in terms of operating costs (in terms of electricity bills). However, more economical units themselves are more expensive. nevertheless, this difference quickly pays off.
Initially, classes were marked in Latin letters from
A(the highest class) and further alphabetically. In the course of technology development, more economical levels of consumption than the original class A appeared — they are labelled as A+,
A++, A+++, etc. Actually, the highest efficiency class in modern dryers is exactly
A +++ ; level A —
A+ can be called good,
B — average, C — acceptable.
Noise level
The noise level generated by the dryer during operation. Usually, the specs indicate the maximum volume of the device, in the noisiest mode — when other programmes are running, this figure may be lower. We note that the noise level also depends on the features of the installation: for example, if the machine does not stand firmly on all four legs, vibration from drum rotation can create additional noise. And the tiled walls amplify the sound by creating an echo. Nevertheless, it is best to evaluate the device precisely by the noise level stated in the specifications. And here it is worth bearing in mind that the decibel used to denote loudness is a non-linear value, and it is best to evaluate the actual loudness of the unit using comparative tables. Here is the simplest such table for the volume range in which modern dryers operate:
65 dB — a person's voice in raised tones at a distance of 1 m;
70 dB — a loud conversation of several people at the same distance;
75 dB — loud laughter at a distance of 1 m;
80 dB — motorcycle engine, medium power vacuum cleaner.
The quieter the machine is, the more comfortable it will be to use and the better it will be suitable for a specific environment (for example, if there is a small child in the house or if you plan to run drying at night). At the same time, it is worth considering not only the actual noise level but also the installation location of the device. If the dryer is planned to...be installed in the basement of a private house with thick ceilings and the bedroom is located on the second floor, you can not pay much attention to the noise level: even the loudest unit is unlikely to create inconvenience.
