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.
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.
Custom programme
Itis an ability to set the machine
custom programme of work. In such a programme, the user can specify the operating parameters (duration, temperature, rotation intensity, etc.) at his discretion; this gives additional options for managing the unit. The custom programme can be useful in non-standard situations, when none of the predefined operating modes is suitable.
Note that the set of parameters that are set when creating your programme may be different in different models; these details need to be clarified separately.
Steam drying
The presence of a
drying programme with steam in the dryer.
In this mode, the laundry in the drum is treated with hot steam. Note that this procedure is not suitable for drying as such; its purpose is rather to refresh and moisturize the fabric. For example, steam drying can be used as an alternative to washing when clean unwashed clothing has absorbed an unpleasant odour. It can be used to moisten overdried laundry for subsequent ironing.
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.
Drain into sewer
This option allows you to automate the process of draining the condensate collection tank (respectively, it is relevant only for dryers with a condensation principle of operation). At the end of the drying process, the condensate accumulated in the tank is automatically drained into the sewer. To do this, a pump and a hose are provided in
a dryer with a drain into the sewer. The function of draining into the sewer allows you to significantly simplify the operation of the dryer, while in models without this option, the user must drain the condensate tank manually. Of course, manual emptying does not require much effort because the average condensate collection tank has a volume of about 5 litres, but still not very convenient.
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.
