Description
BACKGROUND OF THE DISCLOSURE

The present disclosure generally relates to a cooking oven, and more specifically, to a cooking oven where a heating element and bottom walls of a wrapper are removable as a package from a remainder of the cooking oven via fasteners that are accessible from the external environment.


Some cooking ovens provide baking functionality. To provide the baking functionality, the cooking ovens include a heating element disposed beneath a bottom wall defining part of a cooking cavity that accepts a food item for the baking function. The heating element is sometimes attached to a bottom wall of a first outer wrapper as a baking subassembly.


However, there is a problem in that, the heating element may perform suboptimally, and to remove the baking subassembly for servicing of the heating element, a door and side walls of a second outer wrapper typically must first be removed. Initial removal of the door and the side walls of the second outer wrapper is problematic because the removal typically cannot be performed within the owner's house and must be performed off site. The owner sometimes requests an exchange of the cooking oven in need of service with a new cooking oven instead, which is a significant cost. Further, even if product exchange is not requested, the door and the side walls may not be properly aligned after repair of the heating element and reassembly. The lack of proper alignment of the door and the side walls disappoints the owner.


SUMMARY OF THE DISCLOSURE

The present disclosure addresses that problem with a cooking oven that includes a heating element and a bottom wall of an outer wrapper that are coupled as a package, and the package is separable from a remainder of the cooking oven via fasteners that are accessible for manipulation from an external environment.


According to a first aspect of the present disclosure, a cooking oven comprises: (1) an inner liner at least partially defining a cooking chamber and forming an opening into the cooking chamber, the inner liner comprising a bottom wall extending rearward from the opening and forming a floor of the cooking chamber; (2) a first outer wrapper at least partially enveloping the inner liner, the first outer wrapper comprising a bottom wall that is disposed below the bottom wall of the inner liner; (3) a heating element coupled to the bottom wall of the first outer wrapper, the heating element at least partially disposed between the bottom wall of the inner liner and the bottom wall of the first outer wrapper; (4) a forward panel coupled to the inner liner and the bottom wall of the first outer wrapper; and (5) a bracket that is attached to the forward panel and fastened to the bottom wall of the first outer wrapper in a releasable manner via a first fastener comprising (a) a head accessible from an external environment and (b) a threaded shaft extending from the head and, in a first fastened state, extending through (i) an aperture through the bottom wall of the first outer wrapper and (ii) a first aperture of the bracket that is aligned with the aperture of the bottom wall of the first outer wrapper.


These and other features, advantages, and objects of the present disclosure will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.

Referring to FIGS. 1-9, a cooking oven 10 includes an inner liner 12. The inner liner 12 at least partially defines a cooking chamber 14. For example, the inner liner 12 includes a bottom wall 16, a top wall 18 opposing the bottom wall 16, side walls 20, 22 that oppose each other that are generally orthogonal to the bottom wall 16 and the top wall 18, and a rear wall 24 that is generally orthogonal to the bottom wall 16, the top wall 18, and the side walls 20, 22. One contiguous piece of material, such as drawn metal, can provide all of the bottom wall 16, top wall 18, side walls 20, 22, and rear wall 24 of the inner liner 12. In addition, the inner liner 12 forms an opening 26 into the cooking chamber 14. The top wall 18, the bottom wall 16, the side walls 20, 22, and the rear wall 24 are all disposed rearward 28 of the opening 26. The rear wall 24 is disposed rearward 28 of the top wall 18, the bottom wall 16, and the side walls 20, 22. The bottom wall 16 forms a floor 30 of the cooking chamber 14.


Referring additionally to FIGS. 10 and 11, in embodiments, the inner liner 12 further includes a flange 32 that extends away from the opening 26. For example, the flange 32 includes a downward portion 34 that extends downward 36 from the opening 26 near the bottom wall 16 of the inner liner 12. The downward portion 34 is substantially orthogonal to the bottom wall 16 of the inner liner 12. The inner liner 12 can include a lip 38 that defines the opening 26. The flange 32 is rearward 28 of the lip 38.


The cooking oven 10 further includes a door 40. The door 40 is manipulable to, from, and between a closed position 42 (see, e.g., FIGS. 1 and 3) and an open position 44 (see FIG. 2). In the closed position 42, the door 40 denies access from an external environment 46 through the opening 26 and into the cooking chamber 14. “External environment” here means external to the cooking oven 10, such as in a kitchen environment, as illustrated at FIG. 1, when the cooking oven 10 is removed from cabinetry 48 (see FIG. 1). In the open position 44, the door 40 permits access (e.g., does not deny) from the external environment 46 through the opening 26 and into the cooking chamber 14.


In use of the cooking oven 10, a user (not illustrated) can manipulate the door 40 from the closed position 42 to the open position 44. The user can then place a food item 50 (see FIG. 2) within the cooking chamber 14. The user can then manipulate the door 40 back to the closed position 42. The user can then command the cooking oven 10 to perform a cooking operation on the food item 50, such as via a human-machine interface 52 accessible from the external environment 46.


The cooking oven 10 further includes a first outer wrapper 54. The first outer wrapper 54 at least partially envelopes the inner liner 12. For example, the first outer wrapper 54 can include a bottom wall 56 that is disposed below the bottom wall 16 of the inner liner 12, a rear wall 58 that is disposed rearward 28 of the rear wall 24 of the inner liner 12, and a top wall 60 disposed above the top wall 18 of the inner liner 12. The first outer wrapper 54 can further include opposing side walls (not illustrated) that are disposed laterally outward of the side walls of the inner liner 12, but the first outer wrapper 54 need not include such opposing side walls. In embodiments, the top wall 60 of the first outer wrapper 54 is fastened to the rear wall 24 of the inner liner 12.


In embodiments, the rear wall 58 of the first outer wrapper 54 is not fastened to the bottom wall 56 of the first outer wrapper 54. The non-fastening permits easier separation of the bottom wall 56 of the first outer wrapper 54 (and components attached thereto, as will be discussed) from the rear wall 58 of the first outer wrapper 54. For example, in embodiments, the rear wall 58 of the first outer wrapper 54 abuts the bottom wall 56 of the first outer wrapper 54. In such embodiments, the bottom wall 56 of the first outer wrapper 54 includes tabs 62 (see, e.g., FIG. 10) that abut, but are not fastened to, an inward surface 64 of the rear wall 58 of the first outer wrapper 54. The tabs 62 can extend angularly upward 66 and rearward 28 from a primary portion 68 of the bottom wall 56 that is generally horizontal. The rear wall 58 of the first outer wrapper 54 can have an angled section 70 that transitions from the primary portion 68 of the bottom wall 56 of the first outer wrapper 54 to a primary portion 72 of the rear wall 58 that is generally vertical.


Referring additionally to FIGS. 12 through 14, the cooking oven 10 further includes a heating element 74. The heating element 74 is coupled to the bottom wall 56 of the first outer wrapper 54. For example, as in the illustrated embodiment, the cooking oven 10 further includes a heating element bracket 76. The heating element bracket 76 includes a first portion 78 and a second portion 80. The first portion 78 is fastened to the bottom wall 56 of the first outer wrapper 54 with a fastener 82. The second portion 80 is fastened to the heating element 74 with a fastener 84. The heating element bracket 76 is not attached to the inner liner 12, which allows the heating element 74 together with the bottom wall 56 of the first outer wrapper 54 to be separated from the inner liner 12, as will be further discussed. The first portion 78 and the second portion 80 can be generally orthogonal to each other. The bottom wall 56 of the first outer wrapper 54 can include two slots 86 within which a different one of two corners 88 of the first portion 78 of the heating element bracket 76 is disposed.


The heating element 74 is at least partially disposed between the bottom wall 16 of the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. For example, as in the illustrated embodiment, the heating element 74 has a horizontally oriented portion 90 that is disposed entirely or nearly entirely between the bottom wall 16 of the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. The horizontally oriented portion 90 is disposed nearly entirely between the bottom wall 16 of the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. The horizontally oriented portion 90 forward 92 of the heating element bracket 76 is disposed entirely between the bottom wall 16 of the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. The horizontally oriented portion 90 is shaped to form a perimeter of a “U” when viewed from above.


Referring additionally to FIG. 15, in embodiments, such as that illustrated, the first outer wrapper 54 includes projections 94 that extend upward 66 from the bottom wall 56 of the first outer wrapper 54 toward the bottom wall 16 of the inner liner 12. The projections 94 are disposed under and partially around the heating element 74, particularly a lateral crossbar 96 thereof. The projections 94 include a V-shape cutout 98 facing the heating element 74. The projections 94 do not contact the heating element 74. The projections 94 are positioned to limit downward 36 movement of the heating element 74 away from the bottom wall 16 of the inner liner 12.


Referring additionally to FIGS. 16 and 17, the cooking oven 10 further includes a forward panel 100. The forward panel 100 is coupled to both the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. For example, as in the illustrated embodiment, the forward panel 100 includes a first portion 102 that is substantially vertically oriented. The first portion 102 provides a forward surface 104 (see, e.g., FIGS. 7 and 8) that faces the door 40, when the door 40 is in the closed position 42. In addition, the first portion 102 provides a rearward surface 106 that faces the heating element 74 and a space 108 between the inner liner 12 and the bottom wall 56 of the first outer wrapper 54. The forward panel 100 includes a central aperture 110 (see FIGS. 11 and 16) through the first portion 102. The central aperture 110 laterally surrounds the lip 38 of the inner liner 12 and the opening 26 into the cooking chamber 14. The first portion 102 includes a transition portion 112 to provide a change in depth (forward 92-to-rearward 28) of the first portion 102. The transition portion 112 and the first portion 102 near the central aperture 110 form a recess 114 to receive a securing ring 116 that is disposed between the transition portion 112 and the lip 38 of the inner liner 12. The first portion 102 near the central aperture 110 is disposed rearward 28 of the securing ring 116. The rearward surface 106 of the first portion 102 near the central aperture 110 faces the flange 32 of the inner liner 12. The securing ring 116 includes prongs 118 that extend rearward 28 from the recess 114 through apertures 120 through the first portion 102 of the forward panel 100 and through slots 122 of the flange 32 of the inner liner 12 that are aligned with the apertures 120. The prongs 118 are bent inward to couple the forward panel 100 and the inner liner 12 together. The forward panel 100 further includes a second portion 124 that extends rearward 28 from the first portion 102 of the forward panel 100. The second portion 124 includes a bottom section 126 that is substantially horizontally oriented and is disposed between the bottom wall 16 of the inner liner 12 and the first outer wrapper 54.


The cooking oven 10 further includes a bracket 128 that participates in the releasable coupling of the forward panel 100 to the bottom wall 56 of the first outer wrapper 54. The bracket 128 is attached to the forward panel 100, in particular the second portion 124 of the forward panel 100. For example, as in the illustrated embodiment, the bracket 128 is substantially L-shaped and includes a first portion 130 that is substantially horizontally oriented and a second portion 132 that is substantially vertically oriented. The second portion 124 of the forward panel 100 includes a tab 134 that is substantially vertically oriented and an aperture 136 through the tab 134. Likewise, the second portion 132 of the bracket 128 includes an aperture 138 therethrough that is aligned with the aperture 136 through the tab 134 of the forward panel 100. A fastener 140 extends through the aperture 136 through the tab 134 of the forward panel 100 and the aperture 138 through the second portion 132 of the bracket 128 to fasten the forward panel 100 and the bracket 128 together. The tab 134 of the forward panel 100 is disposed laterally outward of the second portion 132 of the bracket 128. The tab 134 of the forward panel 100 and the second portion 132 of the bracket 128 are flush against each other and are both oriented orthogonal to the bottom wall 56 of the first outer wrapper 54.


Referring additionally to FIGS. 18-20, the bracket 128 is fastened to the bottom wall 56 of the first outer wrapper 54 in a releasable manner. The bottom wall 56 of the first outer wrapper 54 includes an aperture 142 therethrough. The first portion 130 of the bracket 128 has an aperture 144 therethrough. The aperture 144 of the first portion 130 of the bracket 128 and the aperture 142 through the bottom wall 56 of the first outer wrapper 54 are aligned. A fastener 146, in a fastened state 190 (see, e.g., FIGS. 17 and 18), fastens the first portion 130 of the bracket 128 and the bottom wall 56 of the first outer wrapper 54 together. More particularly, the fastener 146 includes a head 148 and a threaded shaft 150 that extends upward 66 from the head 148. The threaded shaft 150 extends through the aperture 142 through the bottom wall 56 of the first outer wrapper 54 and the aperture 144 of the first portion 130 of the bracket 128. The threaded shaft 150 extends laterally inward of the tab 134 of the second portion 124 of the forward panel 100.


In embodiments, such as that illustrated, the bottom wall 56 of the first outer wrapper 54 comprises a recess 152. The first portion 130 of the bracket 128 is disposed within the recess 152, substantially flush against the bottom wall 56.


In embodiments, such as that illustrated, the cooking oven 10 further includes a second outer wrapper 154. The second outer wrapper 154 at least partially envelopes the first outer wrapper 54 and the inner liner 12. For example, the second outer wrapper 154 can include a top wall 156, a bottom wall 158, opposing side walls 160, 162, and a rear wall 164. The top wall 156 and the bottom wall 158 of the second outer wrapper 154 oppose each other. The top wall 156 of the second outer wrapper 154 is disposed above the top wall 60 of the first outer wrapper 54 and the top wall 18 of the inner liner 12. The bottom wall 158 of the second outer wrapper 154 is disposed below the bottom wall 56 of the first outer wrapper 54 and the bottom wall 16 of the inner liner 12. The rear wall 164 of the second outer wrapper 154 is disposed rearward 28 of the rear wall 58 of the first outer wrapper 54 and the rear wall 24 of the first inner liner 12. The opposing side walls 160, 162 are disposed laterally outward of the inner liner 12 and in particular the opposing side walls of the inner liner 12. In short, the opposing side walls 160, 162 of the second outer wrapper 154 sandwich the side walls 20, 22 of the inner liner 12. The bottom wall 158 of the second outer wrapper 154 is fastened, in a fastened state 166, to the rear wall 164 of the second outer wrapper 154 and the opposing side walls 160, 162 of the second outer wrapper 154 with fasteners 168. The fasteners 168 are exposed to, and manipulable from, the external environment 46.


Referring additionally to FIG. 21, in embodiments, such as that illustrated, the cooking oven 10 further includes a hinge 170 (see, e.g., FIGS. 8, 9, 12, 16-18, and 20). The hinge 170 couples the door 40 to the second outer wrapper 154. More particularly, the hinge 170 includes a first portion 172 that is fastened to the second outer wrapper 154. The first portion 172 of the hinge 170 is disposed above the bottom wall 158 of the second outer wrapper 154. The first portion 172 of the hinge 170 is disposed laterally inward of the side wall 162 of the second outer wrapper 154 and laterally outward of the bracket 128 connecting the forward panel 100 and the bottom wall 56 of the first outer wrapper 54 together.


In addition, the hinge 170 includes a second portion 174. The second portion 174 is attached to the door 40. The second portion 174 rotates about a pin 176 which is attached to the first portion 172.


Referring additionally to FIG. 22, as mentioned, the fasteners 168 fasten the bottom wall 158 of the second outer wrapper 154 to the rear wall 164 and the opposing side walls 160, 162 of the second outer wrapper 154, in the fastened state 166 thereof. However, because the fasteners 168 are manipulable from the external environment 46, a technician can manipulate the fasteners 168 to take an unfastened state 182, such as with a screwdriver, wrench, or specialty tool. In the unfastened state 166, the fasteners 168 do not fasten the bottom wall 158 to the rear wall 164 and the opposing side walls 160, 162 of the second outer wrapper 154.


As mentioned, the head 148 of the fastener 146 fastening the bottom wall 56 of the first outer wrapper 54 and the bracket 128 together is accessible from the external environment 46. For example, when the cooking oven 10 includes the second outer wrapper 154 with the bottom wall 158, the bottom wall 158 of the second outer wrapper 154 includes an aperture 178 therethrough that allows access to the head 148 of the fastener 146 from the external environment 46. For example, the technician can insert the screwdriver or other tool through the aperture 178 of the bottom wall 158 of the second outer wrapper 154 to manipulate the fastener 146 via the head 148. The fastener 146 can be manipulated to take an unfastened state 180 (see FIG. 20). In the unfastened state 180 of the fastener 146, the threaded shaft 150 of the fastener 146 is removed from the aperture 142 of the bottom wall 56 of the first outer wrapper 54 and the aperture 144 of the bracket 128.


When the fastener 146 is in the unfastened state 180, and the fasteners 168 are in the unfastened state 182, the bottom wall 56 of the first outer wrapper 54, the bottom wall 158 of the second outer wrapper 154, and the heating element 74 are manipulable together as a package 184 (see FIG. 22) to take a separated state 186. In the separated state 186, the package 184 is separated from a remainder 188 of the cooking oven 10. In other words, the door 40, the inner liner 12, and so on all remain together as the remainder 188. Because the package 184 is separable to the separated state 186 from the remainder 188 of the cooking oven 10, the door 40 remains part of the remainder 188 of the cooking oven 10, such as by remaining coupled to the opposing side walls 160, 162 of the second outer wrapper 154 through the hinge 170.


The technician can then replace the heating element 74 of the package 184, or do whatever repair is required to the package 184. The package 184, with the new heating element 74 or otherwise repaired component, can then be combined again with the remainder 188 of the cooking oven 10. The fastener 146 is then manipulated back to the fastened state 190. The fasteners 168 are then manipulated back to the fastened state 166.


In embodiments, the bottom wall 158 of the second outer wrapper 154 and the bottom wall 56 of the first outer wrapper 54 are fastened together with fasteners 202 (see FIGS. 12 and 19). The fasteners 202 each include a head 204 that is inaccessible from the external environment 46. Accordingly, the bottom wall 158 of the second outer wrapper 154 cannot be separated from the bottom wall of the first outer wrapper 54 without first moving the package 184 to the separated state 186.


The present disclosure addresses the problem set forth in the Background, among other reasons, because the technician can repair or replace the heating element 74 without having to first remove the door 40 or the opposing side walls 160, 162 of the second outer wrapper 154. The repair can thus be performed within a kitchen 192 (see FIG. 1) of the owner of the cooking oven 10, without having to move the cooking oven 10 to an off-site repair facility. Performing the repair within the kitchen 192 lessens the likelihood that the owner would request a replacement cooking oven 10.
