Inverter motor
The presence
of an inverter motor in the design of the dryer.
An inverter motor is a motor whose power and speed can be smoothly and accurately adjusted — in contrast to a conventional electric motor, in which adjustments are made in steps. However, the main advantages of machines with this function are low energy consumption and noise level. In addition, inverter motors have relatively few moving parts, which has a positive effect on reliability and durability. Their disadvantages are high price and difficulty in repair.
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.
Controls
The type of control provided in the machine. Almost all modern dryers are equipped with electronic control, so the design of the control panel mainly depends on this parameter. The options here might be:
—
Rotary knob + buttons. The classic option does not lose popularity these days. The rotary knob is usually responsible for selecting the programme and the buttons for controlling additional functions and settings. Such control panels are simple, inexpensive and, at the same time, quite functional. Therefore they are found in all categories of dryers — from low-cost to top.
—
Rotary knob + touch controls. The combination of a rotary knob responsible for selecting the main programme and a set of touch controls that control additional parameters. Compared to the buttons described above, the touch panels have a more stylish and technological appearance; moreover, due to the absence of protruding parts, such a panel almost does not accumulate dirt and is easy to clean. At the same time, these features are generally not fundamental, while the touch controls are somewhat more complicated and expensive than buttons. Therefore, this option is found mainly among dryers of the middle and top classes.
—
Touch controls. This design, on the one hand, gives the device the most accurate and advanced appearance; on the other hand, the control is not as cle
...ar and intuitive as with a handle. Therefore, in its pure form, touch controls are extremely rare — only in high-end dryers.
