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.
Quick dry
Quick dry programme that dries in a relatively short time. It saves time, but the laundry wears out more than during normal drying and is not suitable for delicate types of fabric.
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.
Condensate tank indicator
It is an indicator signalling the filling of the tank with condensate and the need to empty it. It is used exclusively in models with a condensing type of drying (see above). The specific device and functionality of the indicator may be different: in some models, it only warns of a critical liquid level. In others, it can display the exact amount of condensate collected. However, this feature greatly simplifies the monitoring of the operation of the dryer and reduces the risk of flood and other troubles that can lead to an overflow of the tank.
Display
The type of display provided in the design of the dryer.
The screen located on the control panel provides additional convenience: it can display various information about the operation of the machine. In this case, the specific functionality of the screen depends on its type. So, in the vast majority of cases, the simplest
LED displays are used. They can only display numbers and some special characters, but even this is usually sufficient. In some models,
TFT display can be installed — similar to those used in smartphones. Such a display can display not only textual information but also various graphics, and sometimes it is even made touch-sensitive. However, it makes sense to use such screens only in high-end devices with an abundance of functions.
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.
