  • the air duct structure (the structure having the scroll guide which can be controlled so as to be rotated) according to the present invention can be applied not only to a product model such as the frame type air conditioner, the hanger type air conditioner, and a window type air conditioner as shown in FIGs. 3 and 4 but also a variable air duct structure which is of the substantially same type can be applied to, for example, an indoor unit of a stand type air conditioner.
  • the air conditioner and the apparatus for redirecting wind exemplify the case in which they are applied to an indoor unit of the air conditioner for cooling, they can be also effectively applied to indoor units of a separation type air conditioner and a integration type air conditioner and to an outdoor unit for the separation type air conditioner, an outdoor unit for the integration type air conditioner, and indoor and outdoor units of a heater.
  • the air conditioner and the apparatus for redirecting wind according to the present invention can obtain the following effects.
  • sine the initially designed duct passage pattern can be converted to various types of wind direction modes according to selection of the operation mode of a user, the efficiency can be remarkably improved by the optimization of the wind amount and the wind direction.
