A tumble dryer is an appliance used to dry clothes after washing. It works by tumbling wet laundry in a rotating drum while blowing hot air through it. This process helps to evaporate moisture, leaving clothes dry and ready to wear. Tumble dryers come in various types, including vented, condenser, and heat pump models, each with different energy efficiency and installation requirements. Using a tumble dryer can save time compared to air drying, especially in damp or cold weather. However, it's important to follow the manufacturer's instructions for optimal use and maintenance. Regular cleaning of the lint filter and ensuring proper ventilation can enhance performance and safety.
