According to FIG. 1, the hinge according to the invention has.,. a so-hinge member 1, a pivot axis 2, a pull-back and adjusting spring 3 and a fastening element 4o. In the exemplary embodiment described and illustrated here, two identical hinges are provided for mounting the door 5, which are horizontally positioned at the evaporator -6- opens, of which only a section is shown in the drawing. The hinge member 1, which is preferably made of plastic, consists - as shown in detail in Figures 2 and 3 "- of an approximately rectangular plate-shaped body, which on one side over its entire width by a relatively deep Longitudinal slot 7 is divided, which is open on three sides of the body.-1 ₀ This slot 7 is through two lot ~
