Abstract
A dryer includes a drying chamber for the articles to be dried, a supply air duct, a process air duct, a heater in the process air duct for heating process air, a blower that guides the heated process air over the articles to be dried, an exhaust air duct that directs exhaust air to an exhaust air outlet, and an internally and/or externally cleanable lint filter in a recirculated air duct that splits at a branching-off point from the process air duct to the heater and the exhaust air duct which leads to the exhaust air outlet, and wherein the recirculated air duct joins the supply air duct upstream of the heater.

A dryer comprising:
- a drying chamber for the articles to be dried;
- a supply air duct;
- a process air duct;
- a heater in the process air duct for heating process air;
- a blower that guides the heated process air over the articles to be dried;
- an exhaust air duct that directs exhaust air to an exhaust air outlet;
- and
- an internally and/or externally cleanable lint filter in a recirculated air duct that splits at a branching-off point from the process air duct to the heater and the exhaust air duct which leads to the exhaust air outlet, and wherein the recirculated air duct joins the supply air duct upstream of the heater.
A method for operating a dryer having a drying chamber for the articles to be dried, a supply air duct, a process air duct, a heater in the process air duct for heating the process air, a blower that guides the heated process air over the articles to be dried, and an exhaust air duct that directs an exhaust air to an exhaust air outlet, wherein the process air duct splits at a branching-off point into a recirculated air duct to the heater and the exhaust air duct which leads to the exhaust air outlet, wherein an internally and/or externally cleanable lint filter is disposed in the recirculated air duct and the recirculated air duct joins the supply air duct upstream of the heater, the method comprising cleaning the cleanable lint filter with a cleaning device.
