[0051] The specific embodiments, advantages, and features of this disclosure are explained by way of example with reference to the accompanying drawings. Detailed Implementation

[0052] Now for reference Figures 1 to 3 An example of a cooking system 20 is shown. As illustrated, the cooking system 20 includes a base 22 and a cover 24. The base 22 includes a housing 26, which is made of any suitable material (e.g., glass, aluminum, plastic, or stainless steel). A liner 28 may be disposed within the hollow interior 30 of the housing 26. The liner 28 may be formed of any suitable conductive material (e.g., aluminum). In an embodiment, the liner 28 forms the inner surface of the housing 26, thereby defining the hollow interior 30 of the housing 26. Alternatively, the liner 28 may be offset from the inner surface of the housing 26. However, it should be understood that the cooking system 20 or other components of its surface may also define the hollow interior 30.

[0053] The cooking container 32 can be accommodated within the hollow interior 30 of the housing 26. While the cooking container 32 is described herein as removable from the housing 26 at the base 22, embodiments in which the cooking container 32 is integrally formed with the housing 26 are also covered. In these embodiments, the height of the cooking container 32 is greater than the height of the hollow interior 30 of the housing 26. Therefore, when the cooking container 32 is installed within the interior 30, the end of the container extends beyond the adjacent end surface 38 of the housing 26, such as... Figure 3 As shown. The cooking container 32 has an interior or cooking chamber 34, which is designed to receive and hold one or more consumer products, such as food products, therein. Examples of food products suitable for use with the cooking system 20 include, but are not limited to, meat, fish, poultry, bread, rice, grains, pasta, vegetables, fruits, and dairy products, etc. The cooking container 32 may be a pot formed of ceramic, metal, or die-cast aluminum material. In an embodiment, the inner surface of the cooking container 32 includes a nano-ceramic coating, and the outer surface of the cooking container 32 includes an organosilicon epoxy resin material. However, this document covers any suitable material capable of withstanding the high temperatures required for cooking food. In addition, one or more handles may be associated with the cooking container 32 to allow a user to easily grasp and manipulate the cooking container 32 relative to the housing 26.

[0054] One or more attachments may be used with the cooking system 20. Examples of such attachments include, but are not limited to, diffusers, crisping inserts, or scoop baskets (see below). Figure 2 and Figure 3 (e.g., number 36), baking pan, and frying pan. In such embodiments, the accessories may be received within the hollow interior 30 of the housing 26, or within the cooking chamber 34 of the cooking container 32.

[0055] Referring more closely to the lid 24, it should be noted that the lid 24 may be attached to the surface of the cooking container 32 and / or the housing 26 to close the entrance to the cooking chamber 34 of the cooking container 32. Thus, a heating volume may be defined between the cooking chamber 34 of the cooking container 32 and the closed lid 24 (e.g., the bottom surface of the closed lid 24), or between the hollow interior 30 defined by the housing 26 and the closed lid 24. As used herein, the term "heating volume" describes the volume within the cooking system 20 through which fluids can circulate during cooking operations (described in detail below). In an embodiment, the diameter of the lid 24 is substantially complementary to the diameter of the housing 26, such that the lid 24 covers not only the cooking container 32 but also the upper surface 38 of the housing 26.

[0056] The lid 24 can be in an open position relative to the base 22, accessible to the cooking container 32. Figure 2 ) and closing position ( Figure 1 , Figure 3 The lid 24 can move between the base 22 and the cooking chamber 34 to selectively cover the hollow interior 30. The lid 24 may be separate from and separable from the base 22, or the lid 24 may be movably attached to the base 22. Figure 2 In the non-limiting embodiment shown, the cover 24 may pivot or rotate relative to the base 22 about the pivot P (e.g., via the hinge 35). However, other types of movement of the cover 24 are also within the scope of this disclosure.

[0057] When the lid 24 is in the closed position, the lid 24 or a portion thereof may, but not necessarily, be secured to the base 22 using one or more fastening mechanisms (not shown). In embodiments, the fastening mechanisms are selectively engaged when the lid 24 is in the closed position. Alternatively or additionally, the fastening mechanisms are selectively engaged based on the selected cooking operation of the cooking system 20, such as pressure cooking. Any suitable type of fastening mechanism capable of withstanding the heat and pressure associated with the cooking system 20 is considered to be within the scope of this disclosure.

[0058] like Figure 3 As best shown, cover 24 may comprise a generally convex outer cover or cover housing 40 made of any suitable material. In some embodiments, at least a portion of the material of cover housing 40 may be substantially the same as the material of housing 26. An inner cover liner (or sealing liner) 42 is disposed within the hollow interior 44 of cover housing 40. Although inner cover liner 42 is also shown as having a generally convex shape, embodiments in which the shape of inner cover liner 42 differs from the shape of cover housing 40 are also within the scope of this disclosure. Furthermore, inner cover liner 42 may be made of any suitable material, such as glass, aluminum, plastic, or stainless steel, or any combination thereof. Inner cover liner 42 may, but does not necessarily, be made of the same material as cover housing 40.

[0059] In an embodiment, the sealing surface 46 of the lid 24 may be attached to the upper surface 38 of the housing 26 or directly to the cooking container 32 to form a pressure-resistant, airtight seal between the lid 24 and the cooking container 32 or the housing 26. Therefore, the inner surface 54 of the inner lid liner 42 defines the relative upper boundary of the heated volume through which fluid can circulate. In an embodiment, the sealing surface 46 is disposed adjacent to the end of the inner lid liner 42 of the cooking container 32. The sealing surface 46 may be formed from a portion of the inner lid liner 42 itself, or as... Figures 4 to 6 As shown, a flexible / elastic gasket 50 connected to a portion (e.g., its end) of the inner lid liner 42 can define a sealing surface 46. The gasket 50 can be made of rubber, silicone, or other similar materials and may include a flange received within the interior of the cooking container 32. It should be understood that the pressure-resistant, airtight seal formed between the lid 24 and the cooking container 32 or housing 26 can occur during all cooking modes, or only during selected cooking modes, such as those involving pressure or conduction cooking. In embodiments where the pressure-resistant, airtight seal is formed only in selected cooking modes, this seal may not be formed in air-frying or convection modes, and when the lid 24 is closed, the lid 24 can simply rest on the upper surface of the housing 38 or cooking container 32.

[0060] System 20 may also include embodiments in which additional steps must be taken to form a pressure-resistant, airtight seal in addition to simply closing the cap 24. In other words, closing the cap 24 relative to the base 22 may not automatically form a pressure-resistant, airtight seal therebetween. In such exemplary embodiments, the cap 24 further includes a cap lock 52. Figures 4 to 6 As best shown, the lid lock 52 is disposed within the interior of the lid housing 40, for example, substantially concentric with a portion of the inner lid liner 42 relative to the central axis of the lid 24. In the illustrated non-limiting embodiment, the lid lock 52 has an annular or ring-shaped body aligned with the bottom surface of the lid housing 40 and / or the inner lid liner 42. The inner surface 53 of the lid lock 52 may be positioned substantially adjacent to or in direct contact with the outer surface 55 of the inner lid liner 42. In embodiments, the lid lock 52 is movable, for example, rotatable about an axis relative to the lid housing 40 and the inner lid liner 42, selectively applying pressure to move the sealing surface 46 into engagement with the cooking container 32, thereby forming a pressure-sealed, airtight seal therebetween. However, in other embodiments, it should be understood that the closing lid 24 relative to the base 22 may form a pressure-sealed, airtight fit connection between the sealing surface 46 and / or the cooking container 32.

[0061] Whether or not it is necessary to rotate the cover lock 52 to form a pressure-resistant, airtight seal, the cover lock 52 can operate as a locking mechanism that holds or locks the cover 24 in the closed position relative to the base 22. For example, as Figures 5 to 8As shown, the cover lock 52 includes a first part of a bayonet locking system, wherein one or more engaging members 56 formed on the cover lock 52 are engaged by rotating the cover lock 52. Figures 5 to 7 One or more engaging members 58 of the complementary second part of the bayonet locking system extending from the upper portion of the housing 26. Figure 8 The sealing surface 46 is abutted or engaged to limit its movement away from the cooking container 32 in response to increased pressure within the heated volume. In other embodiments where a pressure-resistant, airtight seal is formed when the lid 24 is closed relative to the base 22, a different locking mechanism, distinct from the lid lock 52, may be used to maintain the sealing surface 46 in a sealed engagement with the cooking container 32 when a pressurized environment is generated.

[0062] At least a portion of the lid lock 52, or a portion connected to and extending from the lid lock, may be accessible on the outer surface of the cooking system 20 for user manipulation to selectively lock the lid 24 to the base 22, thereby forming and / or maintaining a pressurized, airtight heating volume defined between the inner surface 54 of the inner lid liner 42 and the cooking chamber 34 of the cooking container 32 (described in more detail below). Figure 1 and Figures 5 to 9 In the best-illustrative, non-limiting embodiment shown herein, the cover lock 52 includes an outwardly extending protrusion 60, also referred to herein as a mode selector, disposed within an opening 62, such as a slot, formed on the outer surface of the cover housing 40. In such embodiments, a user can switch the cover lock 52 between a locked and unlocked configuration by translating the mode selector 60 within the opening 62 between a first and a second position. Although the inner cover liner 42 is described herein as fixed and the cover lock 52 as movable relative to the inner cover liner 42, embodiments in which the inner cover liner 42 is coupled to or formed integrally with the cover lock such that both the inner cover liner 42 and the cover lock 52 are uniformly movable relative to the cover housing 40 are also within the scope of this disclosure.

[0063] Now for reference Figure 1 and Figures 10A to 11B The cover 24 may additionally include a pressure relief mechanism 64, such as a vent or valve. In embodiments where movement of the cover 24 is restricted to maintain a pressure-free seal, the pressure relief mechanism 64 may be formed in a fixed inner cover liner 42, for example, on the upper surface or side surface or in the inner cover liner 42. However, it should be understood that in embodiments where the inner cover liner 42 can rotate about an axis relative to the cover housing 40, the pressure relief mechanism 64 coupled to the inner cover liner 42 may be adapted to be coupled to the inner cover liner 42 only when in the sealed position, or alternatively, to move with the inner cover liner 42.

[0064] The pressure relief mechanism 64 can be configured, for example, during operation of the cooking system 20 in a first cooking mode, to automatically open and release air when the pressure within the heated volume formed between the inner lid liner 42 and the cooking container 32 exceeds a predetermined threshold. Alternatively or additionally, the pressure relief mechanism 64 can be manually operated, for example, by rotating about a vertically oriented axis to release air or fluid from the heated volume. Figures 10A to 11B An example of a manually operable pressure relief mechanism 64 is shown. In the non-limiting embodiment shown, a connector 66, such as a knob, operably coupled to a movable portion 68 of the pressure relief mechanism 64 is arranged on the outer surface of the cover 24 for operator use. When the knob 66 ​​is in the first open position ( Figure 10A ) and the second closed position ( Figure 10B When rotated between the two, the movable portion 68 (e.g., valve stem) is configured to rotate and / or translate to selectively seal or expose an opening formed in the inner cover liner 42 that is in fluid communication with the interior of the cooking container 32.

[0065] The cooking system 20 includes at least one heating element for transferring heat to the heating volume during one or more of a plurality of cooking modes of the cooking system 20. In the illustrated non-limiting embodiment, a first or upper heating element 70 is typically located at or above the upper portion of the cooking container 32, for example, near the center of the interior 34 of the cooking container 32. As shown, at least one first heating element 70 is mounted within the lid 24 (also referred to as lid heating element 70), thus located entirely outside the cooking container 32 and vertically offset from its upper portion. In the illustrated non-limiting embodiment, the first heating element 70 is arranged within the interior 72 of the inner lid liner 42, for example, at a location offset from the inner surface 54 of the inner lid liner 42. In the illustrated non-limiting embodiment, a second or lower or base heating element 74 is also disposed within the housing 26, typically near the bottom 76 of the cooking container 32. However, it should be understood that embodiments in which the heating element is arranged at another location within the base 22 and / or the lid 24 are also contemplated herein.

[0066] At least one first heating element 70 and a second heating element 74 are capable of generating heat of any suitable type. For example, the first heating element 70 and the second heating element 74 configured to heat the cooking container 32 or one or more foods located within the cooking chamber 34 of the cooking container 32 via conduction, convection, radiation, and induction are all within the scope of this disclosure. In the non-limiting embodiments shown, the first heating element 70 can be used to cook food within the cooking container 32 via a non-contact cooking operation. As used herein, the term "non-contact cooking operation" includes any cooking operation in which the heating element or heat source is arranged not to come into direct or indirect contact with the food, such as, but not limited to, convection and radiation heating. In such embodiments, the cooking system 20 further includes an air movement mechanism 78, such as a fan, which can be used to circulate air within the cooking volume. The air is heated as it flows along its circulation path, for example by flowing over a portion of at least one first heating element 70. In such embodiments, the first heating element 70 can be used to perform a convection heating operation. Convection heating operation, also commonly referred to as "dry cooking operation," encompasses any cooking mode that creates a "dry cooking environment" within container 24, such as, but not limited to, air frying, grilling, baking / roasting, and dehydration. To create a dry cooking environment, air and moisture are actively exhausted or vented from the cooking shell to the outside of the cooking system 20, thereby maintaining a minimum humidity level within container 24. Temperatures associated with various exemplary but non-limiting convection / non-contact / dry cooking modes range from approximately 100°F to 475°F. For example, temperatures associated with air frying operations may be between approximately 300°F, temperatures associated with baking operations may be between approximately 250°F and approximately 400°F, temperatures associated with dehydration operations may be between approximately 100°F and approximately 200°F, and grilling operations may be performed at approximately 450°F. However, the temperatures provided herein are intended only as examples, and it should be understood that any cooking mode described herein may be performed at other temperatures.

[0067] In the non-limiting embodiment shown, the air movement mechanism 78 is arranged within the interior 72 of the inner cover liner 42, downstream of the first heating element 70 relative to the air circulation path. The air movement mechanism 78 is driven by a motor 80 having a separate cooling mechanism coupled thereto. Figure 12In the best-illustrated embodiment, the motor 80 is arranged on the side of the inner cover liner 42 opposite to the air movement mechanism 78. Therefore, the motor shaft 82 of the motor 80 extends through an opening 84 formed in the inner cover liner 42. In this embodiment, a sealing device, such as a gasket 86, is positioned between the motor shaft 82 and the inner cover liner 42 to minimize or eliminate friction of the motor shaft 82 during rotation, while maintaining a pressure-free seal with the inner cover liner 42. In this embodiment, the gasket 86 is designed to deflect in response to pressure. In such embodiments, no contact is formed between the motor shaft 82 and the gasket 86 when the heating volume is not pressurized, for example during an air frying operation in which the motor shaft 82 rotates about its axis. Therefore, when the heating volume is not pressurized, the motor shaft 82 is configured to rotate freely, thus eliminating friction with the gasket 86. Furthermore, the motor 80 is not configured to operate when the heating volume is pressurized. Therefore, in response to the pressure within the heating volume, the gasket 86 will deflect to form a retaining feature, which forms an airtight seal with the motor shaft 82, thereby allowing pressure to be generated within the heating volume.

[0068] In an embodiment, the second heating element 74 can be used to cook food within the cooking container 32 via a contact cooking operation. As used herein, the term "contact cooking operation" includes cooking operations in which heat is transferred via direct or indirect contact between a heating element or heat source and the food, such as, but not limited to, conductive cooking. Induction cooking via the lower heating element 74 is also covered herein. It should be understood that embodiments in which the first heating element 70 can be used to perform a contact cooking operation and embodiments in which the second heating element 74 can be used to perform a non-contact cooking operation are also within the scope of this disclosure. Non-contact or conductive cooking operations are generally referred to as "wet cooking" operations, such as, but not limited to, pressure cooking, steam cooking, slow cooking, searing, and frying. To create a wet cooking environment, most of the moisture within the container, i.e., the moisture added to the container 24 or released from the food within the container 24, remains within the container during the cooking of the food. Although a minimal amount of air containing moisture may be expelled from the system during conductive cooking operations, such air is passively expelled from the cooking shell. As used in this article, pressure cooking will allow cooking in a pressurized environment of 40 kPa or above (ranging from 40 kPa to 90 kPa).

[0069] Furthermore, in embodiments including a first heating element 70 and a second heating element 74, it should be understood that the first heating element 70 and the second heating element 74 can be operated independently or in combination to apply one or more predetermined power settings to cook the food product within the cooking container 32. In operation, the first heating element 70 and the second heating element 74 are capable of cooking food independently of the amount of food loaded. In other words, the first heating element 70 and the second heating element 74 are capable of cooking food independently of the amount of food within the cooking container 32. Cooking operations that can be performed by the cooking system 20 include, but are not limited to, pressure cooking, steam cooking, slow cooking, searing, frying, grilling, baking / roasting, dehydration, and grilling.

[0070] refer to Figures 4 to 6 The cover 24 includes a heater / fan cover 90 that protects the user from the first heating element 70 and the air movement mechanism 78, and also protects the first heating element 70 and the air movement mechanism 78 from the area of ​​the cooking system 20 where food is being cooked. In the illustrated non-limiting embodiment, the cover 90 is mounted within the cover 24, for example, adjacent to the first heating element 70 relative to the airflow and more specifically upstream of the first heating element. The size of the cover 90 may be configured to substantially overlap the entire surface of the first heating element 70 facing the cooking volume, and thus protect said entire surface. In one embodiment, the outline of the cover 90 is generally complementary to the shape of the first heating element 70 to protect the surface of the first heating element 70 closest to or facing the cooking chamber 34. However, in other embodiments, the outline of the cover 90 may be complementary to the interior of the cover 24.

[0071] like Figure 5 and Figure 6 As best shown, the lid 90 generally comprises a body formed of any suitable heat-resistant material. The body of the lid 90 has a plurality of openings 92 formed therein to allow hot air circulating within the cooking chamber 34 of the cooking container 32 to pass through. In the non-limiting embodiment shown, the lid 90 has a nano-ceramic coating and is mounted via any suitable mounting mechanism, such as via one or more fasteners, and can be removably or permanently disposed therein. Thus, when the lid 24 is in the closed position, the lid 90 is generally disposed above the first open end of the cooking container 32.

[0072] To prevent pressure within the heating volume from increasing due to temperature rise during non-pressurized cooking operations, the cooking system 20 includes at least one vent for fluidly connecting the heating volume and thus the interior 34 of the cooking container 32 to the ambient atmosphere outside the cooking system 20. Although one or more vents are shown and described herein as being formed in a portion of the cover 24, it should be understood that vents arranged at other suitable locations within the cooking system 20 are also within the scope of this disclosure.

[0073] like Figures 16A to 17C and Figure 19 As best illustrated, the cooking system 20 includes at least one inlet vent 100 and at least one outlet vent 102, through which fluid is configured to flow into the heating volume and through the outlet vent to exit the heating volume. In an embodiment, each of the at least one inlet vent 100 and outlet vent 102 can be used to control the flow rate through the inner cover liner 42 and into or out of the heating volume. Figure 19 As best illustrated, inlet vent 100 and outlet vent 102 each include an opening 103 having an inlet end and an outlet end respectively associated with or defined by the cover housing 40 and the inner cover liner 42. For example, the inlet end of the opening 103 of inlet vent 100 is formed in the cover housing 40, and the outlet end of the opening 103 of inlet vent 100 is located in the inner cover liner 42. Similarly, the inlet end of the opening 103 of outlet vent 102 is disposed in the inner cover liner 42, and the outlet end of the opening 103 of outlet vent 102 is formed in the cover housing 40. Thus, each of the openings 103 defines a fluid flow path extending between the surrounding atmosphere outside the cover 24 and the atmosphere within the interior 72 of the inner cover liner 42. In an embodiment, a conduit 105 may extend between the cover housing 40 and the inner cover liner 42 to define one or more boundaries of the respective fluid flow paths of the inlet vent 100 and outlet vent 102. However, in other embodiments, the portion of the fluid flow path extending between the interior 53 of the cover housing 40 and the exterior 55 of the inner cover liner 42 may be unbounded. In such embodiments, a pressure differential, for example, generated by the operation of the air movement device 78, may be sufficient to move the flow between the inlet and outlet ends of the fluid flow paths in each of the inlet vents 100 and outlet vents 102, respectively. In yet another embodiment, the surface 55 of the inner cover liner 42 may directly abut the surface 53 of the cover housing 40 at the inlet and outlet ends of the openings 103. Thus, the flow through the inlet and outlet ends of each opening 103 can be aligned and directly positioned with each other, allowing the fluid flow to be directly transferred between the body of the cover housing and the body of the inner cover liner 42.

[0074] Refer again Figure 3 The motor 80 may be arranged within a motor cavity 81, isolated from the rest of the interior 44 of the cover 24. As shown, a motor cavity vent 104 in fluid communication with the motor cavity 81 may be formed in the cover 24. Air is configured to flow through the motor cavity 81 to cool the motor 80. In an embodiment, another air movement device 83 (see...) Figure 4 It is positioned within the motor cavity 81. This air movement device 83 can be driven by the motor 81 and can be used to facilitate the flow of cooling air into and out of the motor cavity 81.

[0075] One or more of at least one inlet vent 100 and at least one outlet vent 102 may be adjustable to control the amount of fluid supplied to or discharged from the heated volume, such as air. In an embodiment, each of the at least one inlet vent 100 and at least one outlet vent 102 includes an element 106, such as a flap, ramp, or other mechanism, movable to cover or expose at least a portion of the opening 103 of the inlet vent 100 and the outlet vent 102, respectively. The at least one inlet vent 100 and its associated movable element 106 may be considered a first ventilation system, and the at least one outlet vent 102 and its associated movable element 106 may be considered a second ventilation system.

[0076] exist Figure 13 and Figure 14 In the illustrated embodiment, the movable element 106 is a flap or door arranged on the outer periphery of the inner cover 42, and is vertically movable in and out of contact with the opening 103. (Refer again) Figures 5 to 6 and Figures 15 to 17C The movable element 106 may alternatively be arranged inside the inner cover liner 42, adjacent to the outlet end of the opening 103 of the inlet vent 100 and the inlet end of the opening 103 of the outlet vent 102. In such embodiments, when the cooking container 32 is not pressurized, the movable element 106 is in a first position, at least partially separated from the opening 103. For example, as Figure 15 As shown, during air frying, at least a portion of the movable element 106 is in a vertically lowered position offset from the opening 103, allowing air and steam to flow freely through the opening 103. However, once the pressure within the heating volume increases and exceeds a threshold, the pressure can be configured to act on the movable element 106 and cause it to move. The force exerted by the pressure applied to the movable element 106 can move the element to a second position, such that the movable element 106 blocks or seals the opening 103. Thus, when the movable element 106 is in the second position, for example during pressure cooking, the movable element 106 seals the opening 103, thereby allowing the pressure within the cooking container 32 to increase. However, it should be understood that embodiments including a movable element 106 with a different configuration, as well as embodiments in which the movable element 106 moves in a different manner, are also within the scope of this disclosure.

[0077] In an embodiment, when the movable element 106 moves relative to the housing 26 or the cover 24, a portion of the movable element 106 remains directly adjacent to the opening 103. For example, the movable element 106 may have a first end 108 that remains substantially fixed relative to the adjacent opening 103 and a second end 110 configured to move relative to the opening 103, thereby exposing at least a portion of the opening 103 to allow fluid to flow through it. (Refer again) Figures 16A to 17C In one embodiment, the second end 110 of the movable element 106 is configured to pivot or rotate relative to the opening 103. However, other types of movement, such as translation of the movable element 106, are also covered herein.

[0078] In the illustrated non-limiting embodiment, the movable element 106 is configured to rotate about an axis oriented generally parallel to the axis of rotation of the air movement mechanism 78. In such embodiments, the second movable end 110 may be configured to rotate inward toward the center of the cover 24. Therefore, the flow path defined between the opening 103 and the rotating movable element 106 increases with respect to the flow direction relative to the vents 100, 102. For example, in embodiments where the airflow within the air movement mechanism 78 and thus the interior of the inner cover liner 42 rotates clockwise, the downstream or tail end of the movable element 106 associated with the inlet vent 100 rotates inward. Therefore, the tail end of the movable element 106 adjacent to the opening 103 has a greater airflow capacity than the portion of the opening 103 adjacent to the front end of the movable element 106. Similarly, the upstream or front end of the movable element 106 associated with the outlet vent 102 may be configured to rotate inward. Therefore, the front portion of the opening 103 adjacent to the movable element 106 has a larger airflow capacity compared to the portion at the tail end of the opening 103 adjacent to the movable element 106.

[0079] In this embodiment, the position of the movable element 106 relative to the opening 103 is adjustable to control the flow through one or both of the inlet vent 100 and the outlet vent 102 in response to a selected mode or cooking operation of the cooking system 20. For example, during a first cooking operation, such as an air-frying operation, the inlet vent 100 may be partially or fully opened, allowing fluid to flow through the opening 103 into the heating volume (see...). Figure 5 , Figure 16A and Figure 17A Furthermore, the outlet vent 102 can be opened at least partially or completely to allow air to escape from the cooking container 32, thereby preventing the pressure within the heating volume from increasing in response to the airflow drawn into the heating volume and the operation of the heating element 70. (Refer to...) Figure 6 , Figure 16B , Figure 17B During a second cooking operation, such as pressure cooking, the openings 103 of both the inlet vent 100 and the outlet vent 102 can be sealed or substantially sealed to prevent air from flowing into and out of the heating volume. In such embodiments, a high-pressure cooking environment can be achieved, where the pressure level reaches and / or exceeds 40 kPa. Similarly, in Figure 16C and Figure 17CIn the best illustrated embodiment, during a third operating mode of the cooking system 20, such as a combined pressure cooking and air frying mode, the inlet vent 100 may be partially or fully opened, and the outlet vent 102 may be sealed.

[0080] In an embodiment, the cover lock 52 is used to adjust the position of the movable element 106 of at least one of the inlet vent 100 and the outlet vent 102 to control the flow therethrough. Therefore, a user can switch the cover lock 52 between a first configuration and a second configuration to selectively seal one or more inlet vents 100 and outlet vents 102. For example, when the mode selector 60 is adjacent to the first side of the opening 62 (… Figure 5 , Figure 16A When the cover lock 52 is in the first configuration, or in contact with the first side, at least one of the inlet vent 100 and the outlet vent 102 can be opened, so that the heating volume is not sealed. Similarly, when the mode selector 60 is arranged adjacent to the second opposite side of the opening 62 ( Figure 6 , Figure 16B When the lid lock 52 is in contact with the second opposite side and thus in the second configuration, both the inlet vent 100 and the outlet vent 102 can be sealed, and thus pressure can be created within the heating volume. It should be understood that this movement of the mode selector 60 driving the lid lock 52 to rotate within the opening 62 of the lid housing 40 is merely an example, and any suitable configuration of the lid lock 52 that allows the user to manipulate the sealing surface 46 to selectively form a pressure-resistant, airtight seal with the housing 26 or the cooking container 32 is within the scope of this disclosure.

[0081] In one embodiment, the inner surface 53 of the cover lock 52 may include a ramp-like feature (not shown) configured to cooperate with a biased plunger 112 for mounting the movable element 106 to a portion of the cover 24 adjacent to a corresponding opening 103, such as the inner cover liner 42. As the mode selector 60 rotates within the slot 62, the ramp-like feature engages the plunger 112 and applies an increased force to the plunger opposite to its bias. This force causes the plunger, and thus the movable element 106, to move, for example, away from the opening 103. Movement of the mode selector 60 in the opposite direction causes the ramp-like feature to disengage from the plunger 112, and the biasing force acting on the plunger 112 causes the plunger 112 to return to its intermediate position. In this embodiment, in the intermediate position, the movable element 106 is positioned directly adjacent to the opening 103 to block airflow. Although the engagement of the ramp-like feature and the plunger 112 is described as moving element 106 away from opening 103, it should be understood that this document also covers embodiments in which the engagement of the ramp-like feature and the plunger 112 moves element 106 toward opening 103 and the biasing of the plunger 112 moves element 106 away from opening 103. Furthermore, it should be understood that the cooperation between the cover lock 52 and the movable element 106 as described herein is intended as an example only, and any suitable mechanism for adjusting the configuration of at least one vent is within the scope of this disclosure.

[0082] Although the configuration of the inlet vent 100 and outlet vent 102 is described above as depending on the cooking operation, in other embodiments, the vents 100, 102 may alternatively or additionally be adjusted in response to feedback from one or more sensors disposed within the cooking volume. For example, the temperature of the heating element or within the cooking volume may be monitored by sensors and / or used to control the position of the movable element 106.

[0083] Refer again Figure 1 , Figure 4 and Figure 6 The control panel or user interface 120 of the cooking system 20 is positioned adjacent to one or more sides of the housing 26 or cover 24, such as the front of the housing 26. The control panel 120 includes one or more inputs 122 associated with energizing one or more heating elements 70, 74 of the cooking system 20 by selecting and / or initiating various operating modes of the cooking system 20. One or more of the inputs 122 may include a light or other indicator to indicate to the user that the corresponding input has been selected. The control panel 120 may additionally include a display 124 separate from and associated with at least one input 122.

[0084] like Figure 18As shown, the control system 126 of the cooking system 20 includes a controller or processor 128 for controlling the operation of heating elements 70, 74 and air movement mechanism 78 (including motor 80 and associated fan), and in some embodiments for executing stored heating operation sequences. The controller 128 is operatively coupled to the control panel 120, heating elements 70, 74, air movement mechanism 78, and in some embodiments operatively coupled to movable element 106 for controlling fluid flow through inlet vent 100 and outlet vent 102. Additionally, in embodiments, one or more sensors S for monitoring one or more parameters (e.g., temperature, pressure, lid configuration, etc.) associated with the operation of heating elements 70, 74 may be arranged to communicate with the controller 128. It should be understood that the sensors S may be the same as or alternatively different from the sensors that provide feedback to control fluid flow through inlet vent 100 and / or outlet vent 102. In one embodiment, a first temperature sensor is located within the cover 24 adjacent to the first and second heating elements 70, and a second temperature sensor extends from the bottom surface of the liner 28 adjacent to the second heating element 74. In such embodiments, the first temperature sensor can be used, for example, to monitor temperature when the cover 24 is closed and the first temperature sensor S is arranged in fluid communication with the hollow interior 30 of the cooking system 20. The first temperature sensor can be used to monitor temperature in this way, either alone or in combination with the second temperature sensor.

[0085] As previously described, the cooking system 20 is capable of performing multiple cooking operations, including convection and conduction cooking operations. In such embodiments, cooking operations include, but are not limited to, air frying, pressure cooking, grilling, baking / roasting, dehydration, slow cooking, steaming, searing, stir-frying, and / or any combination thereof. To perform cooking operations that include combinations of multiple types of cooking modes, the food does not need to be removed from the cooking container 32 when the cooking system 20 switches between a first mode (e.g., pressure cooking mode) and a second mode (e.g., air frying mode).

[0086] At least one input 122 can be used to select a mode or cooking operation of the cooking system 20. In an embodiment, the function of the control system 126, and therefore the inputs available to the user, can vary in response to the position of the mode selector 60 of the lid lock 52 and / or in response to the configuration of one or more inlet vents 100 and outlet vents 102, which can be controlled by the mode selector 60. For example, when the mode selector 60 is in a first position associated with a first cooking mode (e.g., a conduction cooking mode), one or more inputs 122 of the control panel 120 can be activated, and when the mode selector 60 is in a second position associated with a second cooking mode (e.g., a convection cooking mode), one or more different inputs can be activated. Furthermore, when the mode selector 60 is in a third position, another set of different inputs can be activated, the third position being positioned between the first and second positions and associated with a third cooking mode, such as a combination cooking mode. In an embodiment, one or more sensors, such as spring switches, can be mounted to the lid lock 52 to indicate the position of the lid lock 52 to the controller 128, and in response, a corresponding portion of the user interface 120 will be powered on for user selection.

[0087] As previously described, the cooking system 20 can operate in a cooking mode using conductive cooking. In conductive cooking mode, the cooking system 20 can perform pressure cooking. In such embodiments, the lid lock 52 is secured to the cooking container 32 or the housing 26 to form a pressure-sealed, airtight shell with the cooking container 32. During operation in pressure cooker mode, the controller 128 initiates the operation of the second heating element 74, thereby increasing the temperature and thus the pressure within the shell formed by the interior of the cooking container 32 and the inner lid liner 42. During operation in pressure cooker mode, the heating element 70 disposed within the lid 24 is normally not energized. In embodiments where the cooking system 20 can operate in pressure cooking mode, the liner 28 should be formed of a more rigid material capable of withstanding the pressure that builds up within the cooking container 32.

[0088] As described above, another cooking mode of the cooking system 20 employs convection cooking, such as performing an air frying operation. When the cooking system 20 is used in air fryer mode, the controller 128 initiates the operation of the first heating element 70 and the air movement mechanism 78 to circulate hot air through the outer shell formed between the cooking container 32 and the inner lid liner 42. During operation in air fryer mode, the second heating element 74 is typically not energized. However, embodiments in which the first heating element 74 is energized are also within the scope of this disclosure.

[0089] The air movement mechanism 78 draws air upward through the adjacent heating element 70 and discharges the hot air outward toward the air guide vent (not shown, and in the exemplary embodiment, it actually surrounds the fan 78). The air guide vent deflects the air downward toward the side of the cooking container 32. The air travels downward through the annular band 130 formed between the cooking container 32 and the basket 36a until it is deflected from the bottom of the cooking container 32 and drawn by the air movement mechanism 78 toward the diffuser 36b and the orifice-patterned ends of the basket 36a. The hot air flows through and between the multiple blades of the air diffuser 36b, which causes the hot air to rotate, thereby creating vortices as the air is drawn into the interior of the basket 36a by the air movement mechanism 78 through the orifices. After passing through the interior of the basket 36a, the air is drawn back through the heating element 70 and enters the air movement mechanism 78 for further circulation.

[0090] As air circulates through the cooking container 32, particularly the basket 36a, the hot air cooks the food placed therein and forms a crisp outer layer due to the Maillard effect. In embodiments, a liquid, such as oil or fat, is contained within the outer shell, for example, at the bottom of the cooking container 32. The liquid may be added to the cooking container 32 prior to operation in air-frying mode, or alternatively, may be generated as residual material as hot air passes through the food within the cooking container 32. In embodiments where the liquid is located at the bottom of the cooking container 32, a portion of the liquid is entrained by the airflow and heated as air circulates through the cooking chamber 34 of the cooking container 32.

[0091] During operation of any cooking mode of the cooking system 20, the controller 128 initiates operation of at least one of the first heating element 70 and the second heating element 74, causing an increase in temperature within the cooking container 32. As previously described, the cooking system 20 may include one or more temperature sensors S for monitoring conditions within the cooking chamber 34. Also as previously described, the first temperature sensor may be positioned near one of the heating elements 70, 74, and the second temperature sensor may be positioned near or adjacent to one of the heating elements in the cooking container 32 to measure its temperature. Upon detecting that the temperature of the adjacent heating elements 70, 74 or within or at the cooking container 32 is equal to or exceeds a predetermined threshold, the controller 128 may de-energize the heating elements 70, 74 until the temperature returns to an acceptable level.

[0092] The cooking system 20 may be further configured to operate in another or a third cooking mode, which serves as a combination of two or more cooking modes. In a combined cooking mode, the cooking system 20 is configured to perform a first cooking operation and a second cooking operation sequentially and in response to a single input provided by the user. In an embodiment, a conductive cooking operation is performed during the first cooking operation of the combined cooking mode, and a convection cooking operation is performed during the second cooking operation of the combined cooking mode. Furthermore, the first cooking operation may be a steam, slow, or pressure cooking operation, and the second cooking operation may be an air-frying operation. In such embodiments, the controller 128 may execute a stored sequence in which the second heating element 74 is operated during a first portion of the sequence to perform the first cooking operation, and the first heating element 70 and the air-moving device 78 are operated during a second portion of the sequence to perform the second cooking operation. For example, in the combined mode, a food such as chicken may be steamed, slow, or pressure cooked via the operation of the second heating element 74. The chicken may then be air-fried by operating the first heating element 70 and the air-moving device 78 to obtain a crispy outer layer. However, the embodiments described herein are intended only as examples, and this document covers any sequence of operations combining both the first heating element 70 and the second heating element 74. When operating in combination of two or more cooking modes, it is not necessary to remove food from the hollow interior 30, or more specifically from the container 32, during such transitions.

[0093] As previously described, the cooking system 20 includes multiple temperature sensors that can be used to monitor the temperature within the cooking chamber 34. Figure 4 In the non-limiting embodiment shown, the cooking system 20 is illustrated with two temperature sensors S1, S2; however, it should be understood that embodiments with more than two temperature sensors are also within the scope of this disclosure. Furthermore, although the temperature sensors S1, S2 are shown arranged substantially in the same location relative to the cooking system 20, for example within a shared housing, in other embodiments, the temperature sensors S1, S2 may be positioned remotely from each other. These sensors S1, S2 may be attached to the lid 24 and / or the housing 26 (or even the container 32) to sense the temperature within the heating volume defined by the container 32 and the inner lid liner 42.

[0094] In this embodiment, one or more of the multiple temperature sensors are negative temperature coefficient (NTC) temperature sensors. Some NTC temperature sensors are designed to operate more accurately at lower temperatures, such as between about 180°F and 245°F (about 80°C to 118°C), while other NTC temperature sensors may be designed to operate more accurately at higher temperatures, such as between about 245°F and 450°F (about 118°C to 232°C). In this embodiment, the cooking system 20 includes at least a first temperature sensor S1 (referred to herein as the “lower temperature sensor”) more suited to monitoring lower temperatures and a second temperature sensor S2 (referred herein as the “higher temperature sensor”) more suited to monitoring higher temperatures. The lower temperature sensor S1 may be adapted to detect the temperature within the cooking chamber 34 during conductive or contact cooking operations. Similarly, the higher temperature sensor S2 may be adapted to detect the temperature within the cooking chamber 34 during convection or non-contact cooking operations.

[0095] During the combined cooking mode, the transition between the first and second cooking operations can occur automatically in response to the temperature detected by at least one of the lower temperature sensor S1 and the higher temperature sensor S2. In an embodiment, when the operation of the cooking system 20 is initiated in the combined cooking mode, both the lower temperature sensor S1 and the higher temperature sensor S2 are operable and transmit signals indicating the sensed temperature to the controller 128. However, the controller 128 will select which signals to read and / or rely on based on the sensed temperature compared to a predetermined threshold associated with the sensors. For example, if the sensed temperature measured by the lower temperature sensor S1 is below, for example, 90°C, the controller will read the signal provided by the lower temperature sensor. However, when the temperature sensed by the lower temperature sensor S1 reaches or exceeds 90°C, the controller 128 will switch from reading the signal provided by the lower temperature sensor S1 to reading the signal provided by the higher temperature sensor S2. Similarly, if, after switching to the higher temperature sensor S2, the sensed temperature measured by the higher temperature sensor S2 remains above, for example, 90°C, the controller will continue to read the signal provided by the higher temperature sensor S2. However, when the temperature sensed by the higher temperature sensor S2 drops to or below a threshold of 90°C, the controller 128 can switch from reading the signal provided by the higher temperature sensor S2 to reading the signal from the lower temperature sensor S1. The thresholds provided herein are intended only as examples. The “switching” or threshold temperature can be any desired range, such as 80°C-130°C, 85°C-125°C, 90°C-120°C, or any low or high value between 80°C and 130°C.

[0096] One or more temperature sensors S of the cooking system 20 may be used to indicate to the controller 128 when to transition from a first cooking operation to a second cooking operation in the combined cooking mode. In an embodiment, the controller 128 may be configured to transition the operation of the cooking system 20 from the first cooking operation to the second cooking operation in response to reaching a predetermined threshold temperature (e.g., but not limited to the temperatures discussed above) associated with one of the lower temperature sensor S1 and the higher temperature sensor S2, respectively. For example, the threshold temperature associated with the lower temperature sensor S2 may be related to the temperature required for convection cooking within the cooking chamber 34. When the threshold temperature is reached, the controller 128 may automatically switch from conductive cooking via the lower heating element 74 to convection cooking via the upper heating element 70. In practice, upon receiving a signal or recognizing a condition instructing the controller 128 to transition the cooking system 20 to the next cooking operation, the controller 128 will de-energize the second heating element 74 and energize the first heating element 70 and the air movement mechanism 78. During the transition to the second cooking operation, the same or different sensors used to monitor the temperature during the first cooking operation may be used to monitor the temperature within the cooking chamber 34. If not, as discussed above, the switching of the cooking mode can occur simultaneously with the switching of the temperature sensor (S1 or S2) being read. In other words, reaching a sensed threshold temperature (e.g., but not limited to, threshold temperatures within the range described above) can signal the controller 128 to automatically switch only the temperature sensor S1 or S2 to be read, the cooking mode, or both the temperature sensor S1 or S2 to be read and the cooking mode to be executed.
