[0022] Referring to FIGS. 1-6B, reference numeral 10 generally designates a vacuum insulated oven cabinet. The vacuum insulated oven cabinet 10 includes a cavity body 14 having an exterior surface 18. An insulation structure 22 having one or more vacuum insulated panels 26 may have the insulation structure 22 welded to the exterior surface 18 of the cavity body 14. The one or more vacuum insulated panels 26 have a hermetically sealed envelope 30 encasing a vacuum core material 34.

[0023] Referring now to FIG. 1, a cooking range 38 includes a burner 42 and a burner grate 46 positioned on a cooktop 50. The cooking range 38 may include one or more burner dials 54 used to control the temperature of both the burners 42 and/or an oven 58. The oven 58 includes an oven door 62 having an insulated oven window 66. Additionally, the oven 58 internally has the vacuum insulated oven cabinet 10 formed by the cavity body 14 (FIG. 2) inside the cooking range 38. The cooking appliance shown in FIG. 1 is the cooking range 38, but it will be understood that this disclosure may equally be applied to microwaves, commercial ovens, and the like, without departing from the teachings provided herein.

[0024] With reference to FIG. 2, a method for forming the cavity body 14 is illustrated. First (step 100), a metal sheet 74 is punched to form one or more crimp lines 78 to form sections corresponding to a bottom cavity wall 82, a left cavity wall 86, a top cavity wall 90, and a right cavity wall 94. Next (step 104), the metal sheet 74 is folded along each of the crimp lines 78 to form a four sided cavity frame 110 that has a corner weld seam 102 to connect the right cavity wall 94 to the bottom cavity wall 82. In some embodiments, the cavity frame 110 does not have a rear cavity wall 98 included as a section on the metal sheet 74 so the rear cavity wall 98 is welded to the cavity frame 110 to form a rear weld seam 106 (step 108). As shown in step 108, once the rear cavity wall 98 is coupled to the cavity frame 110, the cavity body 14 is fully assembled. In some embodiments, the metal sheet 74 may have an additional section attached (not shown) along an additional crimp line 78 to form the rear cavity wall 98 coupled on at least one side to another cavity wall section. In other embodiments, the cavity walls 82-98 may be coupled by stamping or crimping the edges of the walls as an alternative to welding.

[0025] The metal sheet 74 may be formed using any metal or metal alloy known in the art and is not meant to be limiting. In some embodiments, the interior surface of the metal sheet 74 may be enameled and/or additionally stamped to include additional features on the cavity body 14 inside the oven cavity 70.

[0026] With reference to FIGS. 3A-6B, the insulation structure 22 may be alternatively made using a variety of different structures as shown in the different embodiments described herein. One of the similarities found in each of the embodiments detailing the various insulation structures 22 is the use of the hermetically sealed envelope 30. In some embodiments, the hermetically sealed envelope 30 is made from a group of materials including metals, metal alloys, metal foils, or other thin metal materials that are flexible and can maintain a hermetic seal to maintain the vacuum in the respective vacuum insulated panels 26. The metal hermetically sealed envelope 30 of the insulation structure 22 may be soldered or welded to the cavity body 14 to maintain the respective positioning of the insulation structure 22 and cavity body 14 within the vacuum insulated oven cabinet 10. In the embodiments disclosed herein, the insulation structure 22 may be a side paneled insulation structure 116, a one-piece vacuum insulated panel 142, a cavitied insulation wrapper 148, and an insulation wrapper 164. In some embodiments, the cavity body 14 has five walls where each of the five walls is coupled to at least one vacuum insulated panel 26 of the insulated structure 22.

[0027] With reference to FIGS. 3A-3C, in some embodiments the insulation structure 22 may be the side paneled insulation structure 116 which can be made from a foldable metal sheet 114 coupled to one or more vacuum insulated panels 26. As shown in FIGS. 3A-3C, the foldable metal sheet 114 is coupled to a bottom vacuum insulated panel 118, a left vacuum insulated panel 122, a top vacuum insulated panel 126, a right vacuum insulated panel 130, and a rear vacuum insulated panel 134. Each of the vacuum insulated panels (118, 122, 126, 130, 134) are separated by a fold line 138 positioned on the foldable metal sheet 114. The foldable metal sheet 114 coupled to the five vacuum insulated panels 118, 122, 126, 130, 134 are folded along each of the fold lines 138 to form a side paneled insulation structure 116 as the insulation structure 22. FIG. 3C shows the cross-section of the left vacuum insulated panel 122, the rear vacuum insulated panel 134, and the right vacuum insulated panel 130 all coupled through the foldable metal sheet 114. The cross-section of each of these vacuum insulated panels 122, 134, 130 shows the foldable metal sheet 114 coupled to the respective vacuum insulated panel 26. Each of the vacuum insulated panels 26 contain the vacuum core material 34 enclosed by the hermetically sealed outer envelope 30. The vacuum core material 34 may be glass fiber, aerogel, fumed silica, precipitated silica, rice husk ash, perlite, glass microspheres, cynosphere, glass wool, mineral wool, and combinations thereof. In some embodiments, the insulation structure 22 is a side paneled insulation structure 116 formed from a foldable metal sheet 114 coupled to one or more vacuum insulated panels 26 where the one or more vacuum insulated panels 26 may be folded to form the side paneled insulation structure 116.

[0028] In some embodiments, the foldable metal sheet 114 may be made from a variety of metal materials including metals, metal alloys, metal foils, or other thin metal materials that are flexible and can be coupled to maintain a hermetic seal to maintain the vacuum in the respective vacuum insulated panels 26. The side paneled insulation structure 116 may be soldered or welded to the cavity body 14 to maintain the respective positioning of the insulation structure 22 and cavity body 14 within the vacuum insulated oven cabinet 10.

[0029] The vacuum insulated oven cabinets 10 disclosed herein provide several advantages. For example, the use of vacuum insulated panels 26 to form the insulation structure 22 surrounding the cavity body 14 requires less space than the insulation traditionally used to insulate oven cavities. The traditional hyperglass insulation frequently used in the art typically has a thickness of 1 inch to 1.5 inches while vacuum insulated panels may take up half that space. With less internal space needed for insulation the cavity body 14 may be made bigger with a larger volume for cooking space.

[0030] The use of vacuum insulated panels 26 as disclosed herein may reduce the thickness the required insulation by up to 75%, up to 70%, up to 65%, up to 60%, up to 55%, up to 50%, up to 45%, up to 40%, up to 35%, up to 30%, or up to 25%. In some embodiments, the use of vacuum insulated panels 26 to form the insulation structure 22 surrounding the cavity body 14 may have a thickness from 0.25 inches to 0.75 inches, from 0.25 inches to 0.50 inches, or have a thickness of about 0.25 inches, about 0.30 inches, about 0.35 inches, about 0.40 inches, about 0.45 inches, about 0.50 inches, about 0.55 inches, about 0.60 inches, about 0.65 inches, about 0.70 inches, or about 0.75 inches. By reducing the thickness required to insulate the oven cabinet, the cavity body 14 may have both an increased width and an increased height by about 0.50 inches to 1.50 inches, 0.50 inches to 1.0 inches, or by about about 0.50 inches, about 0.55 inches, about 0.60 inches, about 0.65 inches, about 0.70 inches, or about 0.75 inches, about 0.80 inches, about 0.85 inches, about 0.90 inches, about 0.95 inches, about 1.0 inch.

[0031] With reference to FIG. 4, in some embodiments the insulation structure 22 may be the one-piece vacuum insulation panel 142 where the one-piece vacuum insulated panel 142 has at least one flexible joint 146. The cavity body 14 may be positioned within the one piece vacuum insulated panel 142 and the one-piece vacuum insulated panel 142 may be soldered to the cavity body 14. The one-piece vacuum insulated panel 142 may be made from a variety of metal materials including metals, metal alloys, metal foils, or other thin metal materials that are flexible and can be used to maintain a hermetic seal to maintain the vacuum in the one-piece vacuum insulated panel 142. In some embodiments, the insulation structure 22 is a one-piece vacuum insulated panel 142 having one or more flexible joints 146 that surround the exterior surface 18 or walls 82, 86, 90, 94, 98 (FIG. 2) of the cavity body 14.

[0032] Referring now to FIGS. 5A-5C, in some embodiments the insulation structure 22 may be made from the cavitied insulation wrapper 148 having one or more pocket cavities 154 coupled to each wall of the cavity body 14. Each pocket cavity 154 has an outwardly extending flange 158 that may be soldered to close the pocket cavity 154 under vacuum to vacuum seal in an insulation panel 150 or the vacuum core material 34 (FIG. 3C). The insulation panel 150 and/or the vacuum core material 34 may be selected from the group consisting of glass fiber, aerogel, fumed silica, precipitated silica, rice husk ash, perlite, glass microspheres, cynosphere, glass wool, mineral wool, and combinations thereof. Each outwardly extending flange 158 may be soldered around the insulation panel 150 as a vacuum is applied to form each of the final vacuum insulated panels 26. In some embodiments, the cavity body 14 has one or more pocket cavities 154 coupled to the exterior surface 18 to receive an insulation panel 150 or vacuum core material 34 and wherein the pocket cavity 154 has an outwardly extending flange 158 used to weld in and evacuate the insulation panel 150 or vacuum core material 34 to form the one or more vacuum insulated panels 26 in the pocket cavities 154.

[0033] Referring now to FIGS. 6A-6B, in some embodiments the insulation structure 22 may be made by using the cavity body 14 to form part of the vacuum insulated panel 26. For example, the cavity body 14 may have a cavity flange 166 where the cavity body 14 is inserted into an oven wrapper 170 having a oven flange 174. The cavity flange 166 may be welded to the oven flange 174 to form a hermetic seal where the vacuum core material 34 may be added through a fill hole 178 as a vacuum is applied to form the single vacuum insulated panel 26 around the cavity body 14. In some embodiments, a trim breaker strip (not shown) may be used to attach the cavity body 14 to the wrapper 170 of the oven 58 (FIG. 1) if no cavity flange 166 or oven flange 174 is used. In some embodiments, the oven wrapper 170 and oven flange 174 may be made from a variety of metal materials including metals, metal alloys, metal foils, or other thin metal materials that are flexible and can be used to maintain a hermetic seal to maintain the vacuum in the vacuum insulated panel 26 made by the cavity body 14 and oven wrapper 170. In some embodiments, the cavity body 14 has a cavity flange 166 and the cavity body 14 is inserted into an oven wrapper 170 having an oven flange 174 wherein the cavity flange 166 contacts the oven flange 174 and the cavity flange 166 is welded to the oven flange 174 and the vacuum core material 34 is added under a vacuum to form the vacuum insulated panel 26.
