Assembly structure of a cooling air supplying duct for use in a refrigerator having cantilever shelves
An assembly structure of a cooling air supplying duct for use in a refrigerator having cantilever shelves includes a shelf supporting rail having a front wall in which a plurality of engagement slots are formed, and a cooling air discharging duct. The cooling air discharging duct is provided with an engaging opening formed in a portion thereof and a front wall in which a plurality of cooling air discharging holes for discharging cooling air to an interior of the refrigerator are formed. The shelf supporting rail is vertically fixed on an inner wall of the refrigerator and is combined with the cooling air discharging duct by being inserted into the engaging opening.
1. An assembly structure of a cooling air supplying duct for use in a refrigerator having cantilever shelves, the assembly structure comprising:
a shelf supporting rail having a front wall in which a plurality of engagement slots are formed, the shelf supporting rail being vertically fixed on an inner wall of the refrigerator; and
a cooling air discharging duct including:
an engaging opening formed in a portion thereof; and
a front wall in which a plurality of cooling air discharging holes for discharging cooling air to an interior of the refrigerator are formed,
wherein the shelf supporting rail is combined with the cooling air discharging duct by being inserted into the engaging opening, and supports the cantilever shelves; and
wherein both sidewalls of the shelf supporting rail have connection holes formed therein, and elastic plugs are formed on both sidewalls of the engaging opening of the cooling air discharging duct; and
wherein the elastic plugs are engaged into the connection holes when the shelf support rail is inserted into the engaging opening.
2. The assembly structure of claim 1 , further comprising a decorative cover part, wherein when the cantilever shelves are full-width cantilever shelves, a height of the front wall of the shelf supporting rail is less than that of the front wall of the cooling air discharging duct, and the decorative cover part is inserted into the engaging opening after the shelf support rail is inserted into the engaging opening.
3. The assembly structure of claim 1 , wherein when the cantilever shelves are half-width cantilever shelves, a height of the front wall of the shelf supporting rail is substantially equal to that of the front wall of the cooling air discharging duct, and the plurality of the engagement slots formed in the front wall of the shelf supporting rail are arranged in two columns.
