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.
Refresh cycle
A programme designed to remove odours from clothes, such as tobacco smoke, or an unpleasant odour that appears after a long period of storage.
The refresh programme is useful if the clothes are clean, but the smell still needs to be eliminated — refreshing in the dryer takes less time and effort than quick washing and then drying (even if using the same dryer). This function is especially relevant for
drying cabinets.
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.
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.
Control via Internet
It is the ability to control the dryer via the Internet. For example, via a special application on a smartphone or a browser on a PC.
The main advantage of such control is that it can be done from almost anywhere in the world where there is an Internet connection. In addition, this function allows not only to give commands to the unit but also to monitor its condition: for example, the machine can report the remaining operating time, warn the user about various failures, etc. The specific capabilities and technical features
of control via the Internet should be clarified separately. We only note that the connection of the machine to the network is usually carried out via Wi-Fi.
Door opening
The direction in which the door of the dryer opens.
Most users are right-handed, so from this point of view, the best option is
leftward opening — the free space for loading and unloading laundry is just under the right hand. However, specifically in dryers, the
rightward opening is noticeably more common. It is because such units usually complement washing machines and are most often installed side by side. And in most washers, the door opens just to the left (again, based on convenience for right-handed people). Therefore, it is most convenient to place the dryer on the right and equip it with a hatch that opens to the right — this will allow you to overload the laundry from washer to dryer with minimal effort and time. And vice versa, if the door in the washing machine opens to the right, then it is better to choose a dryer with a leftward opening and install it on the left.
Sometimes both machines are installed as a column — a dryer on top of a washing machine. In such cases, the hatches of both machines should open in one direction — this is more convenient both from the point of view of ergonomics and purely psychologically. Moreover, if the "column” adjoins the wall sideways, then the opening should also occur towards the wall; otherwise, the laundry will have to be loaded and unloaded through the space between the open hatch and the wall, which can be very inconvenient.
...
Note that in some dryers both opening options are claimed. It usually means that the door has a reversible mount, and the direction of opening can be chosen at your discretion. However, this feature does not hurt to clarify before buying.
