REFRIGERATOR BOX

Abstract: At a refrigerator (10) box having an inner shell (12) of plastic, an outer shell (14) of plastic, a heat insulation of foam plastic (24) located between the shells, and a plate-formed evaporator (30), a window is taken up in a vertical side (28) of the inner shell (12). The evaporator (30) is mounted in the window so that the surface (34) of the evaporator facing the storage space (36) of the box is located in the same plane as and forms a smooth transition to said side (28). The foam plastic (24) adheres to the rear side (40) of the evaporator (30) and keeps the evaporator on place in the window.

Description: Refrigerator box The invention refers to a refrigerator box with an access opening which is located in a substantially horizontal plane and is closable by a lid, the walls of the box being formed by an inner shell of plastic, an outer shell of plastic and a heat insulation of foam plastic located between the walls, and an evaporator of a refrigerating apparatus being arranged to cool goods in the storage space of the box. The object of the invention is to arrange the evaporator in a simple way so that it will be in direct cooling contact with the space for the goods, will not intrude on the said space and will form a smooth transition to the wall of the space. This object is reached through the refrigerator box according to the invention by a window being taken up in a vertical side of the inner shell, that the evaporator, which has the shape of a plate and covers the window on the side of the inner shell facing the storage space, is mounted in an impression of the edge of the window so that the surface of the evaporator facing the storage space is located in the same plane as and forms a smooth transition to said side, and that sealing means are arranged between the impression and the edge of the evaporator for preventing humidity from moving through the joint between the window and the evaporator, the foam plastic adhering to the rear side of the evaporator and keeping the evaporator on place in the window. An embodiment of a refrigerator box according to the invention is described below in connexion with the enclosed drawing, in which Fig. 1 shows a view of the box without a lid seen from above, Fig. 2 shows a sectional view according to the marking II-II in fig. 1 , and Fig. 3 shows a sectional view according to the marking III-III in fig. 2. By 10 is designated a box constituted by an inner shell 12 and an outer shell 14. The shells 12 and 14 are j oined to each other in a horizontal part 16 , which surrounds an access opening 18 of the box and forms a contact surface for a sealing 20 of a lid 22. A cavity between the shells, which are made of e.g. polyethylene, is filled with a heat insulating plastic foam 24, e.g. polyurethane. A rectangular window 26 is taken up in one vertical side 28 of the inner shell 12. An evaporator 30, which has the shape of a rectangular plate, is mounted in an impression 32 running around the edge of the window, so that the surface 34 of the evaporator, which faces a storage space 36 for goods in the box, is located in the same plane as and forms a smooth transition to the side 28. A sealing 38 is arranged between the impression 32 and the edge of the evaporator for preventing humidity from moving through the joint between the window 26 and the evaporator 30. The evaporator, which can be of aluminium of so-called roll-bond type, is by means of not shown refrigerant conduits connected to a refrigerating apparatus of compression or absorption type. After the sealing 38 and the evaporator 30 have been placed in the window, the cavity between the shells 12 and 14 is filled with the plastic foam, which after hardening adheres to the rear side 40 of the evaporator 30 and keeps the evaporator on place in the box.

Claims: C l a i m s 1. Refrigerator (10) box with an access opening (18) which is located in a substantially horizontal plane and is closable by a lid (22), the walls of the box being formed by an inner shell (12) of plastic, an outer shell (14) of plastic and a heat insulation of foam plastic (24) located between the walls, and an evaporator (30) of a refrigerating apparatus being arranged to cool goods in the storage space (36) ofthe box, characterized in that a window (26) is taken up in a vertical side (28) of the inner shell (12), that the evaporator (30), which has the shape of a plate and covers the window (26) on the side of the inner shell facing the storage space, is mounted in an impression (32) of the edge of the window so that the surface (34) of the evaporator (30) facing the storage space (36) is located in the same plane as and forms a smooth transition to said side (28), and that sealing means (38) are arranged between the impression (32) and the edge of the evaporator for preventing humidity from moving through the joint between the window (26) and the evaporator (30), the foam plastic (24) adhering to the rear side (40) ofthe evaporator (30) and keeping the evaporator on place in the window (26). 2. Refrigerator box according to claim 1 , characterized in that the window (26) and the evaporator (30) have rectangular shape.
