Abstract

An arrangement for rapidly removing condensate from the lower temperature wall (10) of a 0°C compartment or drawer (4) in a refrigerator (1), said compartment (4) being bounded by side walls (6, 7), an upper wall (9), a lower wall (8) and a rear wall (10), the rear wall (10) being refrigerated and presenting on a face (11) facing the interior of the compartment (4) a series of drainage ribs (15) arranged to direct the defrost water and/or condensate formed on it towards a drainage hole (20) positioned at the bottom of said wall (10), a defrost resistance element (18) being present on a second face (12) of the rear wall (10) opposite the first (11). Each rib (15) presents at least two portions (15A, 15B) with different inclinations on the wall (10), the defrost resistance element (18) being arranged to generate greater heat in proximity to a lower portion (1 0K) of the wall (10) close to the lower wall (8) of the compartment (4).
