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.
Moisture sensor
Ability to choose the residual moisture content of the linen to be dried - from completely dry, which can be immediately put in the closet, to slightly dry, which is optimal for ironing. With
laundry moisture control, the user needs to select the desired residual moisture - the dryer will automatically control the condition of the laundry and stop drying at the right time.
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 volume
Only condenser dryers have such a tank (see "Drying type"). The larger the tank, the less often you have to get rid of the accumulated liquid. At the same time, in most models, the volume of the condensate tank is standard — about 5 – 6 litres: this is considered the best compromise between capacity and dimensions.
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.
