A laundry dryer, comprising: a storage portion which stores laundry to be dried; a first duct including a first outlet which opens toward the storage portion; a second duct including a second outlet; a duct switcher which selectively switches between the first and second ducts (9, 11); a blower which blows dry air; an exhaust temperature detector; and a controller; characterized in that: the second outlet has a narrower cross-section allowing air to pass than the first outlet; the blower is configured to blow dry air so that a larger volume of the dry air is blown from the first outlet into the storage portion under selection of the first duct than the second duct and so that the dry air is blown from the second outlet into the storage portion at higher pressure and higher velocity under selection of the second duct than the first duct; the exhaust temperature detector is configured to detect a temperature of the dry air exhausted from the storage portion after the dry air comes into contact with the laundry; and the controller is configured to control the duct switcher in response to a detection result of the exhaust temperature detector to selectively switch between the first and second ducts (9, 11) during a drying process comprising an early drying period, a middle drying period and a final drying period; wherein dry air is blown from the second outlet of the second duct at high pressure and high velocity during the middle drying period, and a large air volume of dry air is blown from the first outlet of the first duct during at least one of the early and final drying periods. a storage portion which stores laundry to be dried; a first duct including a first outlet which opens toward the storage portion; a second duct including a second outlet; a duct switcher which selectively switches between the first and second ducts (9, 11); a blower which blows dry air; an exhaust temperature detector; and a controller; characterized in that: the second outlet has a narrower cross-section allowing air to pass than the first outlet; the blower is configured to blow dry air so that a larger volume of the dry air is blown from the first outlet into the storage portion under selection of the first duct than the second duct and so that the dry air is blown from the second outlet into the storage portion at higher pressure and higher velocity under selection of the second duct than the first duct; the exhaust temperature detector is configured to detect a temperature of the dry air exhausted from the storage portion after the dry air comes into contact with the laundry; and the controller is configured to control the duct switcher in response to a detection result of the exhaust temperature detector to selectively switch between the first and second ducts (9, 11) during a drying process comprising an early drying period, a middle drying period and a final drying period; wherein dry air is blown from the second outlet of the second duct at high pressure and high velocity during the middle drying period, and a large air volume of dry air is blown from the first outlet of the first duct during at least one of the early and final drying periods. the second outlet has a narrower cross-section allowing air to pass than the first outlet; the blower is configured to blow dry air so that a larger volume of the dry air is blown from the first outlet into the storage portion under selection of the first duct than the second duct and so that the dry air is blown from the second outlet into the storage portion at higher pressure and higher velocity under selection of the second duct than the first duct; the exhaust temperature detector is configured to detect a temperature of the dry air exhausted from the storage portion after the dry air comes into contact with the laundry; and the controller is configured to control the duct switcher in response to a detection result of the exhaust temperature detector to selectively switch between the first and second ducts (9, 11) during a drying process comprising an early drying period, a middle drying period and a final drying period; wherein dry air is blown from the second outlet of the second duct at high pressure and high velocity during the middle drying period, and a large air volume of dry air is blown from the first outlet of the first duct during at least one of the early and final drying periods.
