Translation guide
A machine that dries clothes by tumbling them in heated air. In Japanese, the most common term is 乾燥機, often combined with 衣類 or タンブル. Note that many Japanese washing machines have a built-in dryer function, so the standalone appliance is less common.

Shorter, common term for 'dryer', often used when context is clear.

A washer-dryer combo. Literally 'washing machine with clothes dryer'.

In Japan, many people air-dry clothes on a pole or rack (物干し竿/ものほしざお or 室内干し/しつないぼし) instead of using a dryer. If you say 乾燥機, it specifically means an electric dryer, not a drying rack.
乾燥機 can sometimes refer to a hair dryer in certain contexts, but ヘアドライヤー or ドライヤー is much more common for that. Use 衣類乾燥機 to be clear about a clothes dryer.
You can dry futons in the large dryer.
