Embodiment Construction

[0023] The cooling device 1 includes a rear wall 3 having an inner surface 4, an outer surface 5 made of fibrous material, and an insulating material 6 filled in the volume between the inner surface 4 and the outer surface 5. The outer surface 5 is preferably made of cardboard about 2 mm thick. Therefore, the outer surface 5 resists the pressure applied by the heat insulating material 6 during its curing, thereby preventing deformation of the structure of the rear wall 3 in the shape of a rectangular prism. Therefore, the component cost of the outer surface 5 is reduced ( figure 1 , figure 2 , image 3 ).

[0024] The cooling device 1 of the present invention includes one or more protrusions 7 formed on the outer surface 5 at specific intervals. The protrusions 7 are regularly arranged in the horizontal and vertical directions and do not hinder the aesthetic appearance of the outer surface 5. By means of the protrusions 7, the strength of the outer surface 5 is increased and ...

Abstract

The present invention relates to a cooling device (1) comprising a body (2) having a rear wall (3) having an inner surface (4), an outer surface (5) produced from cellulosic material and an insulation material (6) filled in the volume between the inner surface (4) and the outer surface (5), and wherein the insulation material (6) is prevented from forming deformations on the outer surface (5) during its solidification.

Description

Technical field [0001] The invention relates to a cooling device comprising a rear wall having an outer surface made of fibrous material. Background technique [0002] In cooling devices, particularly in refrigerators and freezers, a heat insulating material is filled between the inner surface and the outer surface of the body to provide heat insulation between the inner volume and the outer environment. Due to its chemical structure, the insulating material, which is preferably polyurethane, will expand and solidifies (solidifies) once it is filled into the body of the cooling device. In some cooling devices, the outer surface of the rear wall that is invisible to the user is made of fibrous materials such as paper, cardboard, and cardboard. In these cooling devices, the insulating material deforms the outer surface of the rear wall during its solidification. This situation leads to a reduction in the quality of user experience.
