  • the door features three layers of transparent panels in addition to the outer protective transparent panel 22. More specifically, the door features an interior transparent panel 32, outer surface transparent panel 34 and inner surface transparent panel 36.
  • the space between interior transparent panel 32 and outer surface transparent panel 34, indicated at 38 in Figs. 5 and 7, and the space between interior transparent panel 32 and inner surface transparent panel 36, indicated at 42 in Figs. 5 and 7, are vacuum insulated.
  • the transparent panels 22, 32, 34 and 36 may be constructed from acrylic, glass or any other transparent material.
  • a frame indicated at 44 in Figs. 5, 7 and 8, and indicated in general at 44 in Fig. 9, features a circumferential slot 46 (Fig. 9) that holds the interior transparent panel 32 circumferentially by its edges.
  • the frame also includes a chamber 50 that travels the circumference or perimeter of the frame and that houses multiple light-emitting diodes (LEDs) as illustrated at 52 in Figs. 5 and 7.
  • LEDs light-emitting diodes
  • the LEDs 52 run along the top and bottom and both sides of the frame 44.
  • the LEDs receive power via electric cord 54 of Figs. 1-3.
  • the frame includes a passage 54 that travels the circumference or perimeter of the frame.
  • This passage is filled with molecular mesh, indicated at 56 in Figs. 5 and 7, to provide insulation to interior transparent panel 32. While LEDs are illustrated and described herein, alternative light sources may be used. In addition, alternative insulation materials known in the art may be substituted for the molecular mesh 56.
  • Frame 44 may be constructed from aluminum, plastic or a variety of other materials, preferably providing low levels of heat transfer. [0025] As illustrated in Fig. 5, outer surface transparent panel 34 is secured against frame 44 by inwardly protruding portions 57 of left and right door posts 24a and 24b, as well as outer protective transparent panel 22 and inwardly protruding portions 59 of top end and bottom end caps 26a and 26b (Fig. 7).
  • the interior transparent panel or sheet 32 features a V- shaped channel 58 formed or etched therein that forms a decoration that illuminates when lit from the side by the LEDs 52 of Figs. 5 and 7.
  • the angle of the channel (indicated at 62 in Fig. 12) may be approximately 90°.
  • Alternative channel shapes may be used, as long as the channel catches the light produced by LEDs 52 of Figs. 5 and 7 as they travel through the interior sheet 32.
  • a bottle shape is illustrated as the decoration in Fig. 10, the decorative shape may obviously take other shapes and could optionally include text.
  • an insulation bridge 66 travels around the periphery of inner surface transparent panel 36 and is secured to top and bottom caps 26a and 26b by pins 68 (as illustrated in Fig. 7) and to right and left door posts 24a and 24b by pins 72 (as illustrated in Fig. 5).

Abstract

L'invention concerne une porte décorative pour un réfrigérateur, qui comprend un cadre présentant une fente périphérique et une chambre périphérique qui sont en communication l'une avec l'autre. Le cadre est adapté pour être monté au réfrigérateur de façon articulée. Un panneau transparent intérieur est fixé par ses bords à l'intérieur de la fente périphérique du cadre et présente un canal décoratif formé dans celui-ci. Un nombre de diodes électroluminescentes servent de sources de lumière disposées dans la chambre périphérique et éclairent le canal décoratif du panneau transparent intérieur. Les panneaux transparents de surface interne et de surface externe sont montés sur le cadre sur des côtés opposés du panneau transparent intérieur et les espaces entre ceux-ci sont au moins partiellement évacués d'air. Le cadre comprend également un passage périphérique contenant un matériau isolant, tel qu'un réseau moléculaire.
