A dryer caught fire overnight at a property at Lilac Street, Lee Mount, Halifax.
A couple and two girls were in the house and the man was able to drag the machine into the back garden.
One of the girls remained in the house breathing air from an open attic window.
When firefighters from Illingworth and Halifax arrived shortly before 1.30 am they put the fire out in the garden but the property was heavily smoke-logged.
They cleared the house of smoke before leading the girl to safety. She was unhurt.
The man was taken to the Calderdale Royal Infirmary suffering from slight smoke inhalation.
A fire investigation team is looking into the cause of the fire.
