Cool air discharge controller for refrigerator and controlling method

Abstract

A cool air discharge controller for a refrigerator and a controlling method thereof are provided. The cool air discharge controller includes: a front panel member which is installed at the rear wall of a refrigeration compartment of the refrigerator for providing a plurality of cool air discharge apertures; a rotary cool air discharge member detachably installed onto the front panel member, for dispersedly discharging the cool air into the refrigeration compartment; a driving motor installed at the upper portion of the rotary cool air discharge member for driving the rotary cool air discharge member; a position detecting switch installed at the upper portion of the rotary cool air discharge member, for defining a reference position of the rotary cool air discharge member; a grill cover detachably coupled to the front of the front panel member, for protecting the rotary cool air discharge member and guiding the cool air to be discharged; a thermal insulating member coupled at the rear side of the front panel member, for providing a loading position of a cool air guiding portion of the rotary cool air discharge member and a cool air flowing path; a damper baffle installed at the upper portion of the thermal insulating member, for controlling the amount of the cool air introduced into the refrigeration compartment; and a seal panel member coupled at the rear side of the thermal insulating member, for protecting the thermal insulating member by constituting a housing in cooperation with the front panel member. Thus, the cool air is dispersedly discharged by the rotary cool air discharge member.
