It should be understood that the frame 70 may support or couple the conductive wire mesh and/or panel in a variety of ways, methods, and constructions and still be electrically grounded to the frame. For example, as shown in FIG. 12, the panel 50 and/or conductive mesh layer 40 may be molded to the frame 70 (e.g. frame made of a conductive plastic material), or portions thereof. Moreover, nonconductive engagements may be included to support the panel in some embodiments. If used, the frame, or portions thereof, may be a variety of materials, quantities, shapes, sizes, and constructions and still be with the scope of the invention.

In some implementations, the conductive mesh layer 40 and/or multi-layered shielding panel 50 may be formed to be substantially the entire frame. As shown in FIG. 10, the multi-layered panel 50 may be formed without a metal frame portion. The panel and/or conductive mesh may include an outer periphery 51 with a choke groove 50b as shown in the one embodiment in FIG. 10.

In some embodiments, the door may include one or more protective layers 25 (e.g. glass) interior and/or exterior to the conductive mesh layer or panel. In various embodiments, the protective glass layers 25 may be spaced away from the panel and/or mesh layer towards and/or away from the cooking cavity 14 in the window 30. The protective layers 25 may reduce unwanted contact with portions of the door, interior panel 50, and/or mesh layer 40. The one or more protective layers 25 may be on one or more opposing sides of the panel 50. A variety of tapes, sealants, and/or gaskets may be used to attach the protective layer with the door/frame, or portions thereof.

In some implementations, a leak detection device or apparatus 80 may be used to detect microwaves undesirably escaping from the microwave oven cooking cavity 14. The leak detection device 80 may be used to alert the consumer or user in proximity to the microwave cooking appliance 10 and/or remotely to another device (e.g. tablet, phone, etc.). The leak detection device 80 may be activated by the microwaves escaping from the cavity (e.g. through portions of the door and/or around the perimeter of the door). For example, in some embodiments, the microwaves or microwave energy may escape away from or adjacent to at least the frame 70 and/or mesh layer 40, or portions of the door 20.

In some embodiments, the leak detection device 80, if used, may include one or more light sources 81. The one or more light sources may be activated if the microwaves or microwave energy escape from the cavity (e.g. conductive and/or sealing engagements 60). The light sources 81 may be configured to be in an off configuration and do not illuminate when there are no microwaves present or escaping, or one or more threshold amounts (e.g. predetermined) of microwaves has not been reached. The one or more light sources 81 may be in an on configuration and illuminate when the microwaves are present or escaping one or more portions of the door/housing, or the one or more threshold amounts (e.g. predetermined) of microwaves has been reached. In some implementations, one or more light sources 81 may be in the on configuration adjacent to and/or distal from the leakage or microwaves escaping. For example, in the embodiments shown in the Figures, the one or more light sources 81 may illuminate when in the on configuration adjacent to the escaping microwaves or the light sources are adjacent thereto. Alternatively, the leak detection device does not have to be activated directly by the microwaves as in the present embodiment. The one or more light sources may be distal from the leakage and be configured to receive a signal or be activated remotely from the leakage, therefore not powered from the microwaves. It should be understood that the light sources, if used, of the leak detection device may be a variety of sizes, shapes, materials, constructions, quantities, and positions with the door (e.g. frame, mesh layer, etc.), or portions thereof, and still be within the scope of the invention. For example in the one embodiment shown, the light sources may include LEDs.

In some implementations, the one or more light sources or leak detection device, if used, may be one or more LEDs 82. The LEDs 82 may be positioned in a variety of positions within the door 20. In some embodiments, the LEDs may be positioned in the door of the microwave appliance as shown. Alternatively, the LEDs or light source may be positioned within the housing and/or door. In various embodiments as shown in the Figures, if a light source 81 is used, the one or more light sources or LEDs may be positioned in an annular pattern or be annularly spaced within the door (e.g. exterior side 20b of the door 20). The annular pattern of the LEDs 82 may be rectangular in shape having one or more sides about the window 30 or through opening 74. As shown in the one embodiment in FIGS. 1-12, the one or more LEDs may be positioned or embedded in a plastic piece or strip 83. In some embodiments as shown in FIG. 12, the LEDs 82 may not be embedded in a strip in the exterior side 20b of the door. For example, the one or more LEDs may be embedded, in contact with, or positioned adjacent the mesh layer 40, or other portions of the panel 50 or door.

The light source or leak detection device may be in a variety of positions and still be within the scope of the invention. The one or more light sources 81 or leak detection device 80 may be in a variety of positions transverse to the direction D, from an inward facing or interior side 20a of the door 20 facing the cooking cavity 14 towards the outward facing or exterior side 20b of the door 20 facing away from the cooking cavity 14. As shown in the one embodiment, the one or more light sources 81 may be spaced inwardly from the perimeter or seal/engagement of the door 20 to the housing 12 (e.g. area surrounding the opening/cavity to insert or remove food). As shown in FIGS. 6-8, 9, and 12, the one or more light sources 81 or leak detection device 80 may be adjacent to the inner periphery 73 and/or through opening 74 of the frame 70. In some embodiments, as shown in FIGS. 6-8, 9, and 12, the leak detection device 80 or LEDs 82 may be adjacent the conductive engagement 60 between the mesh layer 40 and the frame 70. If no frame is used, for example in FIG. 10, the LEDs 82 may be positioned at a variety of locations relative to the plane of the mesh layer 40, or portions thereof. The leak detection device or LEDs may be positioned adjacent the outer periphery 57 of the mesh layer or panel 50 in some embodiments. For example, as shown in FIG. 10, the LEDs may be positioned interior of the choke 51 or adjacent the outer periphery 57 of the panel 50, or portions thereof. The one or more light sources may be spaced inwardly from the choke, spaced outwardly from the choke, or alternately adjacent to the choke. In some embodiments, as shown in FIGS. 3-5 and 11, the light source 81 or LEDs 82 may be positioned or spaced outwardly from the conductive engagement 60, through opening 74, mesh layer 40, window 30, and/or panel 50.

The one or more light sources or leak detection device may be in a variety of positions in the direction D from an inward facing or interior side 20a of the door 20 facing the cooking cavity 14 towards the outward facing or exterior side 20b of the door 20 facing away from the cooking cavity 14. The LEDs or leak detection device may be on the exterior side 20b of the door. As shown in the embodiments in FIGS. 1-11, the LEDs 82 or light source 81 may be spaced away from or outwardly from the mesh layer 40, frame 70, conductive engagements 60, or panel 50, or portions thereof. In some embodiments, the light source (e.g. LEDs) may be adjacent to, contact, or be embedded in one or more of the wire mesh layer 40, one or more glass layers 52 of the panel 50, one or more of the conductive engagements 60, choke 51, user interface display 190, and/or protective layers 25. As shown in the one embodiment in FIG. 12, the one or more light sources 81 (e.g. LEDs) may contact the wire mesh layer 40 at one or more positions.

It should be understood that the leak detection device, if used, of the multi-layered shielding panel 50, frame 70, door 20, and/or mesh layer 40 may be a variety of sizes, shapes, materials, positions, quantities, and constructions with the door (e.g. frame, mesh layer, conductive engagements, etc.), or portions thereof, and still be within the scope of the invention.

In some implementations, the microwave cooking appliance 10 or portions thereof (e.g. door) may include one or more user interface displays 190 (e.g. panel, layer, screen, film, etc.). The user interface display 190 may be used to present and/or receive (e.g. electronic, verbal, audio, visual, etc.) content 191a-e such as, but is not limited to, food characteristics (e.g. before, during, and/or after cooking), controls 18, cooking functions, nutritional value, allergy information, advertisements, recipe information, visual/audio media, information, timer, clock, moisture readings, cooking cavity conditions, alerts, leak detection 80, communication, etc. The user interface display 190 may be transparent in one or more applications, continuously or discontinuously. The user interface display 190 may be transparent or in a transparent configuration (e.g. when door is open/closed) to allow a consumer to see through the door 20/window 30 and/or into the cooking cavity 14 and view the contents therein. The content (e.g. food, etc.), or portions thereof, may be visible through the window 30 or portions of the door 20 when the door is in the open positon and/or closed position. The window 30, through opening 74, or portions of the door 20 may allow the consumer to see through at least the user interface display 190, mesh layer 40, multi-layered shielding panel 50, protective layer 25, and/or other portions of the door into the cavity 14. Alternately, the transparent user interface display 190 may become opaque (e.g. temporarily and/or predetermined) or placed in an opaque configuration to reduce the visibility through the door/window (e.g. when open and/or closed). It should be understood that the user interface display, if used, may be a variety of content, sizes, shapes, materials, positions, quantities, and constructions with the door (e.g. frame, mesh layer, conductive engagements, window, leak detection, etc.), or portions thereof, and still be within the scope of the invention.

In some embodiments as shown in the Figures, the user interface display 190 or portions thereof may include one or more touch screens 192 or be touch-sensitive. One or more users can touch the touch screen 192, if used, to present, operate, receive, access, or manage input/output or the content 191a-e (e.g. controls 18) as described above. The content 191a-e may be added or removed from the user interface display 190 in some embodiments. It should be understood that the touch screen, if used, of the user interface display may be a variety of sizes, shapes, materials, positions, quantities, and constructions with the door (e.g. frame, mesh layer, conductive engagements, etc.), or portions thereof, and still be within the scope of the invention.

In some implementations as shown in FIGS. 1 and 2, the door 20, or portions thereof, may include one or more of the controls 18 of the microwave cooking appliance. The user interface display 190 or touch screen 192 may include one or more of the controls 18 to operate one or more characteristics/functions of the microwave cooking appliance 10. The one or more controls and/or touch screen may be configured to receive input from the user.

In some embodiments, the content 191a-e or portions of the user interface display 190 (e.g. touch screen 192) may be fixed and/or movable between one or more positons across the panel 193 or surface area. The layout of the touch screen 192 or user interface display 190 may be adjustable and/or fixed. The user may move content or controls 18 between positons on all or part of the touch screen and/or user interface display. The user may hide or show one or more of the contents/controls on the user interface display. One or more contents 191a-e may be presented for one or more predetermined times or a variety of times at one or more portions or all of the display/surface.

In some embodiments, the user interface display 190 may include a panel 193 (e.g. transparent). The panel 193 may include one or more layers. The user interface display 190 (e.g. panel 193) may be positioned on the exterior side 20b of the door 20 in the direction D away from the cooking cavity 14, mesh layer 40, panel 50, and/or frame 70. The user interface display is shown in the Figures as spaced away from the multi-layered shielding panel 50 and/or frame 70, or portions thereof, however the one of more portions of the user interface display may be adjacent thereto. The user interface display, or portions thereof, may be disposed in the window 30 of the door, or portions thereof. The user interface display or portions thereof may be disposed over the conductive mesh layer 40, or portions thereof. In some embodiments, the user interface display or portions thereof may be disposed over the frame 70, choke 75, multi-layered shielding panel 50, through opening 74, conductive engagement 60, or portions of the door. The one or more layers of the panel 193 may be made from glass, plexiglass, or other transparent or substantially transparent material. For example, the panel may be an LCD, LED, or OLED panel. Moreover, the panel 193 may be a single layer or a multi-layered structure.

In some implementations, the user interface display 190 or panel 193 may also include one or more additional layers, if used, on one or more sides thereof in the direction D. As shown in the FIGS. 3-12, one or more front layers or outer protective layers 194, if used, may be on the exterior side of the user interface display or panel 193. The outer protective layer 194, if used, may protect the user interface display panel 193 or touch screen 192. Although not shown, one or more rear panels or inner protective layers may be positioned between the user interface panel 193 and the cooking cavity 14. One or more portions of the outer and/or inner protective layers, if used, may be made from glass (e.g. insulated, tempered, etc.), plastics, or other transparent or substantially transparent material. The outer and/or inner protective layers may protect the panel 193 from impact/moisture damage.

In some embodiments, the microwave cooking appliance 10 may include a variety of connections 13 in communication with the user interface display 190 and/or leak detection 80. As shown in the one embodiment in FIG. 2, the user interface display may be powered and/or connected by one or more contact pins 13a to one or more portions or components of the appliance 10. The door 20 may include one or more contact pins 13a that correspond to one or more contact pins 13a with the remaining portion of the housing 14. When the door 20 is in the closed position (FIG. 1), the one or more contact pins 13a of the door 20 and remaining portion of the housing 12 engage each other to enable communication between the appliance, or portions thereof. When the door is in the open position (FIG. 2), the one or more contact pins 13a are disengaged from each other and may place one or more components of the appliance out of communication with each other. In some embodiments, one or more wires 13b, if used, may connect the user interface display 190 and/or leak detection 80 alone or in combination with the contact pin engagement, if used. Although the one or more wires 13b are shown as passing through the hinge of the door 20, the one or more wires may not pass through the door hinge in various embodiments.

A microwave cooking appliance 10 consistent with the invention also may include one or more controllers 15 configured to control the cooking cavity 14 and otherwise perform cooking operations at the direction of a user. In addition, as will become more apparent below, a controller 15 of a cooking appliance in some embodiments may also be configured to detect leakage of microwaves (e.g., via leak detection 80 and/or light source 81) and/or control the user interface display 190 (e.g. content 191a-e and/or controls 18, etc.), or portions thereof.

Controller 15 may receive inputs from a number of components and drives a number of components in response thereto. Controller 15 may, for example, include one or more processors and a memory within which may be stored program code for execution by the one or more processors. The memory may be embedded in controller, but may also be considered to include volatile and/or non-volatile memories, cache memories, flash memories, programmable read-only memories, read-only memories, etc., as well as memory storage physically located elsewhere from controller 15, e.g., in a mass storage device or on a remote computer interfaced with controller 15.

Controller 15 may be interfaced with various components, including cooking cavity 14 used for cooking food (e.g. microwave), one or more user controls 18 for receiving user input (e.g. various combinations of switches, knobs, buttons, sliders, touchscreens or touch-sensitive displays, microphones or audio input devices, image capture devices), leak detection 80, light source 81, alarms, etc., and the user interface displays 190 (e.g. including various indicators, touch screens, graphical displays, textual displays, etc.), as well as various additional components suitable for use in a cooking appliance. In some embodiments, the user interface display 190, or portions thereof, may include or be coupled with the leak detection 80 (e.g. light source, alerts, alarms, etc.) in some embodiments to alert the user of escaping microwaves. For example, the content 191a-e may include the leak detection 80, alert, or light source therein to indicate escaping microwaves.

Controller 15 may also be interfaced with leak detection 80 located to sense escaping microwave conditions inside of and/or external to cooking appliance 10 (e.g. light, audible/acoustic, visual, etc.). The leak detection 80 may be coupled to the controller 15 in a variety of ways (e.g. wired and/or contact pins). Such leak detection 80 may be internal or external to cooking appliance 10, and may be coupled wirelessly to controller 15 in some embodiments.

Controller 15 may also be interfaced with user interface display 190 located to communicate conditions inside of and/or external to cooking appliance 10 (e.g. light, audible/acoustic, visual, content, controls, etc.). The user interface display 190 may be coupled to the controller 15 in a variety of ways (e.g. wired and/or contact pins). Such user interface display 190 may be internal or external to cooking appliance 10, and may be coupled wirelessly to controller 15 in some embodiments. Controller 15 may manage the transparent panel 193 or additional layers to be configured between the transparent configuration and the opaque configuration, if used.

In some embodiments, controller 15 may also be coupled to one or more network interfaces, e.g., for interfacing with external devices via wired and/or wireless networks such as Ethernet, Wi-Fi, Bluetooth, NFC, cellular, and other suitable networks. Network may incorporate in some embodiments a home automation network, and various communication protocols may be supported, including various types of home automation communication protocols. In other embodiments, other wireless protocols, e.g., Wi-Fi or Bluetooth, may be used.

In some embodiments, microwave cooking appliance 10 may be interfaced with one or more user devices over the network, e.g., computers, tablets, smart phones, wearable devices, etc., and through which cooking appliance 10 may be controlled and/or cooking appliance 10 may provide user feedback. A user device, for example, may be configured to perform various operations with the user interface display and/or leak detection.

In some embodiments, controller 15 may operate under the control of an operating system and may execute or otherwise rely upon various computer software applications, components, programs, objects, modules, data structures, etc. In addition, controller 15 may also incorporate hardware logic to implement some or all of the functionality disclosed herein. Further, in some embodiments, the sequences of operations performed by controller 15 to implement the embodiments disclosed herein may be implemented using program code including one or more instructions that are resident at various times in various memory and storage devices, and that, when read and executed by one or more hardware-based processors, perform the operations embodying desired functionality. Moreover, in some embodiments, such program code may be distributed as a program product in a variety of forms, and that the invention applies equally regardless of the particular type of computer readable media used to actually carry out the distribution, including, for example, non-transitory computer readable storage media. In addition, it will be appreciated that the various operations described herein may be combined, split, reordered, reversed, varied, omitted, parallelized and/or supplemented with other techniques known in the art, and therefore, the invention is not limited to the particular sequences of operations described herein.

While several embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, embodiments may be practiced otherwise than as specifically described and claimed. Embodiments of the present disclosure are directed to each individual feature, system, article, material, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, and/or methods, if such features, systems, articles, materials, and/or methods are not mutually inconsistent, is included within the scope of the present disclosure.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.

The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of” or “exactly one of” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.

In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.

It is to be understood that the embodiments are not limited in its application to the details of construction and the arrangement of components set forth in the description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Unless limited otherwise, the terms “connected,” “coupled,” “in communication with,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.

The foregoing description of several embodiments of the invention has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.
