Embodiment Construction

[0028] The refrigerator (1) comprises: an inner shell (2) forming the inner part of the body and / or the door; an outer shell (3) forming the outer part of the body and / or the door; a compartment (4), the perimeter of the compartment (4) is delimited by the inner shell (2), in which food and beverages are stored; and the insulating volume (5), which is located in the inner Between the shell (2) and the outer shell (3), an insulating material such as polyurethane is injected into this insulating volume (5).

[0029] A plastic backing plate (6) is used to manufacture the inner shell (2).

[0030] The backing plate ( 6 ) is firstly in the shape of a flat plate, which is later given its final shape by thermoforming in a mould, in order to manufacture the inner shell ( 2 ).

[0031] In the refrigerator (1) of the present invention, the liner plate (6) forming the inner shell (2) includes: a main body layer (7), which is made of HIPS (impact polystyrene) material through extrusion ...

Abstract

The present invention relates to a refrigerator (1) wherein plastic liner sheets (6) are used in manufacturing the inner casings (2) of the body and / or the doors, the liner sheet (6) forming the inner casing (2) comprising a main layer (7) produced of HIPS (high impact polystyrene) material by extrusion process, and a protective layer (8) which is formed on the (inner) surface of the main layer (7) facing the compartment (4) by co-extrusion method, having a high chemical resistance and a gloss that is not decreased below a certain limit.

Description

technical field [0001] The present invention relates to a refrigerator in which a plastic liner is used in the manufacture of the inner shell of the body. Background technique [0002] Backing panels of plastic material such as polystyrene (HIPS - High Impact Polystyrene) are used in the manufacture of the inner shell of the refrigerator body or door and are manufactured by extrusion methods and these panels are formed by thermoforming processes their final shape. In the refrigerator, substances with acidic properties (such as cooking oil and oil vapor) will be smeared on the body and the inner shell of the door during use, and the cleaning agent for cleaning the inner shell will have residues, which have abrasive effects, And create cracks by breaking polymer bonds. Since the plastic material used to make the inner shell is also subjected to thermal stress during the operation of the refrigerator, material fatigue will develop and when combined with chemical abrasion, the...
