Abstract

A refrigerated sales cabinet comprises a cabinet body providing a refrigerated sales space for supporting refrigerated goods to be presented therein; at least one door; and a door frame having a top post, a bottom post, and at least two upright posts. At least one of the posts comprises a main body having a constant cross-section including a rear wall portion, two side wall portions, respectively extending forward from the rear wall portion, and a support member extending between the two side wall portions. An insulating front element is attached to the support member by means of at least one connection element located in a central area of the support member of the main body, the central area laterally spaced apart from the two side wall portions.

Claims

1. A refrigerated sales cabinet, comprising:

a cabinet body providing a refrigerated sales space for supporting refrigerated goods to be presented therein;

at least one door;

a door frame having a top post, a bottom post, and at least two upright posts;

wherein at least one of the posts comprises;

a main body having a constant cross-section including a rear wall portion, two side wall portions, respectively extending forward from the rear wall portion, and a support member extending between the two side wall portions;

an insulating front element, which is attached to the support member by means of at least one connection element located in a central area of the support member of the main body, the central area being laterally spaced apart from the two side wall portions;

wherein the width of the area of contact at the connection element between the insulating front element and the support member, seen in a cross-sectional view, is less than 10% of the width of the support member.

2. The refrigerated sales cabinet of claim 1, wherein the insulating front element is attached to the support member of the main body by means of a snap-on connection comprising a first fastening bracket formed at the support member that engages with a corresponding second fastening bracket formed at the rear side of the insulating front element.

3. The refrigerated sales cabinet of claim 2, wherein the fastening brackets respectively comprise at least one hook, the hooks of the first and second fastening brackets hooking into each other in order to attach the insulating front element to the main body.

4. The refrigerated sales cabinet of claim 3, wherein the at least one hook of the insulating front element is provided with an inclined surface facing away from the insulating front element.

5. The refrigerated sales cabinet of claim 3, wherein the at least one hook of the main body is provided with an inclined surface facing away from the main body.

6. The refrigerated sales cabinet of claim 2, wherein the fastening brackets are formed as extruded elements extending along the length of the post.

7. The refrigerated sales cabinet of claim 1, wherein the snap-on connection is symmetrical with respect to a symmetry plane of the post.

8. The refrigerated sales cabinet of claim 1, wherein there is no contact between the insulating front element and the main body other than the contact provided by the at least one connection element.

9. The refrigerated sales cabinet of claim 8, wherein there is at least one gap of at least 3 mm between the insulating front element and the main body.

10. The refrigerated sales cabinet of claim 1, comprising an electrical heater arranged in the insulating front element.

11. The refrigerated sales cabinet of claim 1, wherein said insulating front element comprises, from back to front, a rear panel, a front panel forming the front surface of the post, and a thermally insulating layer arranged between the rear panel and the front panel.

12. The refrigerated sales cabinet of claim 11, wherein said thermally insulating layer is sandwiched between said rear panel and said front panel.

13. The refrigerated sales cabinet of claim 11, wherein at least one of the rear panel and the front panel comprises a plastic material.

14. The refrigerated sales cabinet of claim 11, wherein the rear panel and the front panel are attached to each other by means of a second snap-on connection provided by third and fourth fastening bracket members.

15. The refrigerated sales cabinet of claim 11, wherein at least one of a front surface of the front panel and a portion of the rear panel is covered with a thermally insulating coating.

16. The refrigerated sales cabinet of claim 11, wherein an electrical heater is arranged adjacent to the front panel.

17. The refrigerated sales cabinet of claim 11, wherein the thermally insulating layer comprises at least one of a thermally insulating foam, a nanoporous aerogel and a vacuum panel.

18. The refrigerated sales cabinet of claim 11, wherein said rear panel and said front panel together with two respective side wall strips completely enclose said thermally insulating layer.

19. The refrigerated sales cabinet of claim 15, wherein the coating employs nano-technology for providing thermal insulation.

20. The refrigerated sales cabinet of claim 11, wherein an electrical heater is arranged adjacent in contact with the front panel.

21. A method of reducing condensation at the front of a refrigerated sales cabinet comprising:

a cabinet body providing a refrigerated sales space for supporting refrigerated goods to be sold therein;

at least one door;

a door frame having a top post, a bottom post, and at least two upright posts, each of the posts having a main body comprising a rear portion, two side portions extending from the rear portion and a support member extending between the two side portions;

wherein the method comprises;

attaching a thermally insulating front element to the main body by means of at least one connection element, which is arranged at a central area of the support member of the main body, wherein said central portion is laterally spaced apart from the two side portions, and wherein the extension of the area of contact between the insulating front element and the support member provided by the connection element in a direction parallel to the horizontal extension of the insulating front element is less than 10% of said horizontal extension of the insulating front element.
