Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the priority, under 35 U.S.C. § 119, of Turkish Patent Application TR 2020/015497, filed Sep. 30, 2020; the prior application is herewith incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a refrigeration device including a cabinet, a thermally-insulated housing which surrounds the cabinet and has a sidewall facing outward and an inner liner spaced apart from the sidewall, and at least one door which is hinged to the housing by at least one hinge element.

The region of the housing where the door is hinged to the housing, is exposed to forces during the lifecycle of the refrigeration devices. Therefore, that region of the housing should have a more rigid structure.

European Patent EP 0206258 B1, corresponding to U.S. Pat. No. 4,632,470, discloses a refrigerator cabinet having an outer metal case including side walls and a top wall, a plastic inner liner and a partition separating freezer and fresh food compartments and separate front door openings. A front face is formed along the front edge of the side walls and top wall defining the door openings. The front face along each side wall is provided with a first pair of vertically spaced openings disposed in the area adjacent the partition and a lower pair of vertically spaced openings disposed in the lower end of the front face. A support frame system is provided including vertically extending side support bars, each having pairs of vertically spaced upper and lower openings dimensioned to align with the upper and lower openings in the front face. An upper cross member extending between the side walls is positioned adjacent the front portion of the partition and a lower cross member extending between the lower edge portion of the side walls. The upper and lower cross members include a pair of vertically spaced openings adjacent each end thereof which are cooperatively disposed relative to the upper and lower pair of vertically spaced openings in the front face and support bar. Securing devices cooperating with the aligned upper and lower pairs of vertically spaced openings in the front face, support bar and their respective cross members for securely holding the cross members substantially perpendicular relative to the cabinet side walls thereby ensure that the front door openings are maintained in a substantially square relationship.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter is explained with references to examples without forming any restrictive effect and only in order to make the subject more understandable.

Referring now to the figures of the drawings in detail and first, particularly, to FIG. 1 thereof, there is seen a refrigeration device 1 which includes a cabinet 2 surrounded by a thermally-insulated housing 3. The cabinet 2 can be a freezer compartment or a fridge compartment. The thermally-insulated housing 3 has a sidewall 5 facing outside and an inner liner 4 spaced apart from the sidewall 5. The cabinet 2 has an access opening for accessing the interior of the cabinet 2 from outside. At least one door 7 is hinged to the housing 3 by at least one hinge element 8 for opening/closing the access opening. As can be seen in FIG. 1, the exemplary refrigeration device 1 has a pair of doors 7 hinged to the housing 3. The pair of doors can be a French-type door. The housing 3 further includes a front frame part 6 provided at a side of the housing 3 facing the door 7. The front frame part 6 connects to the inner liner 4 from one side and to the sidewall 5 from the other side. An insulation material (not shown) fills a spacing between the inner liner 4, the sidewall 5 and the front frame part 6.

As can be seen in FIGS. 2 and 5, in a possible embodiment of the invention, the housing 3 further includes a reinforcing member 13 provided at a region of the housing 3 adjacent the respective hinge element 8. The reinforcing member 13 connects a pair of frame parts 11, 12 extending vertically between the sidewall 5 and the inner liner 4, to each other, and to the respective hinge element 8 and sidewall 5. In FIG. 3, detail A shows the region of the housing 3 adjacent the respective hinge element 8. The hinge element 8 attaches to a hinge connection housing 9 provided at a front side of the refrigeration device 1 facing the door 7. At least one first connection region 15 and at least one second connection region 16 are provided in the region of the housing 3. In a possible embodiment, there are two first connection regions 15 and two second connection regions 16 provided in the region of the housing 3. In FIG. 4, detail A shows the exploded view of the region of the housing 3 adjacent the respective hinge element 8. The sidewall 5 has a plurality of connection openings 21. A connection element 22 passes through each of the connection openings 21. Preferably, the connection element 22 is a rivet element.

With reference to FIG. 5, in a possible embodiment of the invention, the reinforcing member 13 is located at a middle region of the housing 3 in the vertical direction. The reinforcing member 13 is configured to extend in a vertical direction of the housing 3. The pair of frame parts 11, 12 of the housing 3 extends vertically between the sidewall 5 and the inner liner 4. In more detail, a first frame part 11 extends from the middle of the housing 3 to the upper side in the vertical direction, and a second frame part 12 extends from the middle of the housing 3 to the lower side in the vertical direction. The reinforcing member 13 connects to the first frame part 11 from one side, and to the second frame part 12 from the other side. There is a hinge support part 10 provided in the hinge connection housing 9 on a side adjacent the reinforcing member 13. As can be seen in FIG. 6, the reinforcing member 13 and the frame parts 11, 12 are configured to extend in the vertical direction of the housing 3. At least a part of the reinforcing member 13 overlaps a part of the first frame part 11. Similarly, at least a part of the reinforcing member 13 overlaps a part of the second frame part 12. The reinforcing member 13 has one or more second connection hole 18 on a part of the reinforcing member 13 that is not overlapping with the respective frame parts 11, 12. In a possible embodiment, the reinforcing member 13 has two second connection holes 18.

With reference to FIGS. 7 and 8, in a possible embodiment, the reinforcing member 13 has three-sided connection surfaces. The reinforcing member 13 has a first side surface 23 facing the sidewall 5, where a plurality of connection holes 17, 18 are provided. The connection holes 17, 18 are spaced apart from each other in the vertical direction. The connection openings 21 of the sidewall 5 correspond to the connection holes 17, 18. In more detail, the first side surface 23 has one or more first connection holes 17 and one or more second connection holes 18. A connection element 22 passes through the first connection hole 17, the connection opening 21 of the sidewall 5 and the respective frame parts 11, 12. Thus, the reinforcing member 13 connects to the sidewall 5 and the respective frame parts 11, 12. A connection element 22 passes through the second connection hole 18 for connecting the reinforcing member 13 to the hinge support part 10 from outside of the housing 3. The reinforcing member 13 further includes two connection lugs 14 provided at the opposite sides. The connection lugs 14 at least partly overlap a part of the respective frame parts 11, 12. The connection lugs 14 are configured to extend in a direction perpendicular to the first side surface 23. Each of the connection lugs 14 have one or more third connection hole 19. A connection element passes through the third connection hole 19 and the respective frame parts 11, 12. Thus, the reinforcing member 13 connects to the first frame part 11 and the second frame part 12. The reinforcing member 13 has one or more fourth connection hole 20 provided on a second side surface 24 which is perpendicular to the first side surface 23. A connection element passes through the fourth connection hole 20 in order to connect the reinforcing member 13 to the hinge support part 10. In a possible embodiment, the reinforcing member 13 is made from a metal material, in particular a steel material.
