DETAILED DESCRIPTION
[0040] Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one exemplary embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.
[0041] A cooking device is provided having multiple cooking modes, a vent, an outwardly swinging door, and a condensation collection system. In an exemplary embodiment, the cooking device includes multiple cooking modes including a steam cooking mode and an air fry cooking mode, and the device can be configured to transition from the steam cooking mode to the air fry cooking mode during a single cooking operation. In the steam cooking mode, a moisture level within the device’s cooking compartment increases, and thus condensation collects on internal walls of the device, including the device’s outwardly swinging door. It is important when a user opens the door that the collected condensation does not drip form the door, collecting on the support surface which the device is resting on, such as a countertop. Accordingly, a condensation collection system is provided that is configured to allow for the collection of fluid, such as water, into an internal volume of the housing, and for dispensing of the collected fluid from within an internal volume of the housing to a collection area positioned outside of the cooking chamber.
[0042] FIGS. 1-9 illustrate an exemplary embodiment of a cooking device 300 configured to perform multiple cooking operations. The cooking device 300 is substantially similar to the cooking device disclosed in U.S. Patent No. 11,490,761, entitled “Single Opening Vent For Steam Air Fryer” issued on Nov. 8, 2022, which is hereby incorporated by reference in its entirety. As such, like components and operations between the two cooking devices are not described in detail. [0043] As shown in FIG. 1, the cooking device 300 generally includes a door 302 and a housing 306, with the door 302 attached to the housing 306.
[0044] As depicted in FIG. 3, arranged inside of the housing 306 is a cooking compartment (also referred to herein as a “cooking chamber”) 303, which is accessible via an opening 305 arranged in the housing 306. A consumable container 307 is receivable inside the cooking compartment 303. The container 307 has an interior designed to receive and retain one or more consumable products, such as food products. Examples of food products suitable for use with the cooking device 300, include but are not limited to meats, fish, poultry, bread, rice, grains, pasta, vegetables, fruits, and dairy products, among others.
[0045] As depicted in FIG. 2A, the cooking device 300 includes one or more heating elements
352, 353 for heating the cooking compartment 303. A first heating element 352 is positioned generally at or above an upper extent of the cooking compartment 303 and therefore may be completely outside of the area which the container 307 is inserted into the cooking compartment 303. A second heating element 353 is located generally adjacent a bottom of the cooking compartment 303 and can be completely outside of the area which the container 307 is inserted into the cooking compartment 303.
[0046] As illustrated in FIG. 2A, an air movement device 356 is selectively operable to circulate a flow of fluid, for example air, through the cooking chamber 303. The air movement device 356 includes a motor 358 having a fan 359 coupled thereto. The air movement device 356 is operable to circulate air within the cooking chamber 303 through the at least one heating element 352,
353. As the air passes over the at least one heating element 352, 353, the air is heated for cooking the consumable within the cooking chamber 303. In an exemplary embodiment, the air movement device 356 can be mounted within the upper portion of the cooking compartment 303 at a position vertically offset from the first heating element 352. However, other configurations of the air movement device 356 relative to the first heating element 352, for example a concentric arrangement of the air movement device 356 and the first heating element 352, are also contemplated herein.
[0047] As shown in FIG. 1, a control panel or user interface 360 of the cooking device 300 is positioned on a handle 361 of the door 302, although the control panel 360 can be located elsewhere on the cooking device 300. The control panel 360 includes one or more inputs 362 associated with energizing the at least one heating element 352, 353 of the cooking device 300 and for selecting various modes of operation of the cooking device 300. One or more of the inputs 362 can include a light or other indicator to show that the respective input has been selected. The control panel 360 can additionally include a display 364 separate from and associated with the at least one input 362. However, embodiments where the display 364 is integrated into the at least one input 362 are also contemplated herein. Additionally, portions of the control panel 360 can be activated via the position of a switching mechanism 330.
[0048] The switching mechanism 330 is connected to a vent assembly 331, which is configured to control a flow of humid air from the housing 306. The switching mechanism 330 is configured to move the vent assembly 331 from an open position (for air-frying) to a closed positon (for steaming). In order to achieve both a steam cooking operation and an air frying operation within the same unit, the high humidity air must be removed from the system and replaced with less humid air. By using a single vent assembly 331, the single vent assembly’s inlet and outlet must be spaced apart to prevent the inlet taking in high humidity air from the outlet. The single vent assembly 331 is substantially similar to the single vent design disclosed in previously mentioned U.S. Patent No. 11,490,761, which is hereby incorporated by reference.
[0049] When the vent assembly 331 is in a closed position, the display 364 is configured to be illuminated to inform a user that the cooking device 330 can be operated in a first cooking mode. A first portion of the display 364 is related to the first cooking mode, and can include options related to the first cooking mode, such as steaming, proofing, and steam and crisp processes. In some embodiments, this information is displayed in any of a variety of ways, with the illustrated display 364 having a first portion configured to show information related to the first cooking mode and a second, different portion of the display 364 configured to show information related to the second cooking mode, which may help a user easily discern that information is being shown in relation to a particular cooking mode based on where the information is shown on the display 364. When the vent assembly 331 is in an open position, the display 364 is configured to be illuminated to inform a user that the cooking device 330 can be operated in a second cooking mode. A second portion of the display 364 is related to the second cooking mode, and can include options related to the second cooking mode, such as air frying, baking, roasting, searing, and slow cooking processes. In an exemplary embodiment, the inputs 362 only function with the one of the first and second portions of the display 364 that is active due to the position of the switching mechanism 330.
[0050] Illustrated in FIG. 2B, a control system 370 of the cooking device 300 includes a controller or processor 372 configured to control operation of the one or more heating elements 352, 353 and operation of the air movement device 356 (including the motor 358 and fan 359 associated therewith). In some embodiments, the control system 370 is additionally configured to execute stored sequences of heating operation. The processor 372 is configured to be operably coupled to the control panel 360, the one or more heating elements 352, 353, and the air movement device 356.
[0051] In addition, in some embodiments, one or more sensors S each configured to monitor one or more parameters (such as temperature, pressure, door open/closed configuration, etc.) associated with operation of the one or more heating elements 352, 353 can be arranged in communication with the processor 372. In one embodiment, a sensor S can be configured to monitor whether the door 302 is in a closed configuration. Alternatively, or in addition, a sensor S can be configured to monitor a temperature within the cooking compartment 303.
[0052] Accordingly, during a steam cooking operation, the processor 372 is configured to initiate operation of the one or more heating elements 352, 353, causing the temperature within the cooking compartment 303 to increase. This temperature increase would cause any fluid or moisture within the cooking chamber 303, either fluid directly arranged in the cooking chamber 303 or naturally embedded within the consumable located within the chamber 303, to vaporize. With the air movement device 356 active, the fluid may become entrained within the air circulating through the cooking compartment 303. As a result, when the air and fluid is heated as it passes over the at least one heating element 352, 353, causing the fluid to become a gas, such as water vapor or steam. This transformation of a liquid to a vapor performed within the cooking compartment 303 in response to the heat generated by the at least one heating element 352, 353 causes not only the pressure, but also the humidity, within the cooking compartment 303 to increase. This steam can then form condensation on the interior surface of the cooking compartment 303, including an interior surface 304 of the door 302.
[0053] As shown in FIG. 3, the door 302 is configured to open along a vertical axis 308 to control access to the cooking chamber 303 through an opening 305 on a front side of the housing 306. The door 302 is arranged such that the interior surface 304 of the door 302 abuts the housing 306 when the door 302 in in the closed position.
[0054] Still referring to FIG. 3, it should be noted that the door 302 is connectable to a front surface of the housing 306 to close off entry to the interior of the cooking compartment 303. Accordingly, when the door 302 is closed, the cooking compartment 303 can be defined by interior surfaces of the housing 306 and the interior surface 304 of the door 302. An area of the door 302 can be complementary to an area of the housing 306 such that the door 302 covers the opening 305 of the housing 306. The door 302 can be made of any suitable material, such as glass, aluminum, plastic, or stainless steel. Further, the door 302 can, but need not, include one or more handles 361 for removably coupling the door 302 to the remainder of the cooking device 300.
[0055] As previously discussed, the cooking appliance 300 is configured to heat food in a variety of cooking modes. One or more of these modes, for example, steaming, can produce condensation along an interior surface of the cooking chamber 303, including the interior surface 304 of the door 302. The embodiments described throughout this disclosure may prevent, reduce, or mitigate liquid build-up on the interior surface 304 of the door 302. As illustrated in FIGS. 3-7B, a seal 310 including a protrusion 320 is located between the door 302 and the housing 306. In some embodiments, the seal 310 is attached or otherwise fixed to the door. For example as shown in FIGS. 5-6, the seal 310 can include tabs 504 extending from a rear portion 509 of the seal 310. In order to fasten the seal 310 to the door 302, the tabs 509 are arranged within holes on the door 302, and then a fastening plate 600 can be arranged over the rear portion 509 and connected to the door 302 to tension the seal between the fastening plate 600 and the inner surface of the door 302. Other ways of fastening the seal 310 to the door 302 can be used without departing from this disclosure, for example, adhesives, interference fits, or fasteners can be used. The seal 310 can be formed from silicon, rubber, or any suitable heat restraint sealing material.
[0056] As illustrated in FIG. 8, the seal 310 comprises an elongate body 318 and a protrusion 320. The elongate body 318 and the protrusion 320 each extend horizontally along a bottom region of the interior surface 304 of the door 302. The elongate body 318 is formed from a flexible material and includes a top surface 322 and first and second side arms 324, 326, described below in more detail. The protrusion 320 includes a base 328, a first side 332, a second side 334, and an outer edge 336. The base 328 contacts the top surface 322 of elongate body 318 at a middle portion 338 of the top surface 322 and maintains contact thereat along the entire length of the seal 310. The first side 332 and the second side 334 each extend outward from the base 328 in a direction perpendicular to the top surface 322. The first side 332 and the second side 334 join together at the outer edge 336. Returning to the elongate body, the first side arm 324 is adjacent to the first side 332 of protrusion 320 and the second side arm 326 is adjacent to the second side 334 of protrusion 320. The first side arm 324 is defined by a first curve 340 of elongate body 318. The first curve 340 curls outwardly from base 328 and away from the top surface 322 and toward the interior surface 304 of the door 302. The second side arm 326 is defined by a second curve 342 of elongate body 318. The second curve 342 curls outwardly from base 328 and away from the top surface 322 and toward the cooking chamber 303.
[0057] As shown in FIG. 8, the seal 310 at least partially defines a seal channel 508 along a lower portion of the door 302. The seal channel 508 is arranged and configured to receive condensation from the interior, vertical surface 304 of the door 302. In some embodiments, the seal channel 508 is partially defined by the door 302 itself. Regardless of the seal channel components, the seal channel 508 extends across a lower portion of the door 302. In some embodiments, the seal channel 508 can extend further around the perimeter of the door, for example to reduce risk of installation failures due to improper orientation. As illustrated in FIG. 6, the seal 310 can include an opening 510 arranged at one end of the seal channel 508 in order to allow water to drain from the seal channel 508. A tapered section 507 can positioned on the protrusion 320 in order to aid in water drainage. Additionally, as illustrated in FIG. 7A, a rounded comer 506 of the protrusion 320 can be positioned opposite the tapered section 507 to aid in the collection of water.
[0058] To maintain the seal channel 508, the seal 310 is configured to rotate between a first orientation when the door 302 is open and a second orientation when the door 302 is closed. As illustrated in FIG. 8, when the door 302 is open, the protrusion 320 is angled away from the interior surface 304 of the door 302. In this first orientation, seal 310 is uncompressed and liquid that has formed on the interior surface 304 of the door 302 can flow from the inner surface 304 to the first side 332 of the protrusion 320, as illustrated by the arrows in FIG. 8. The protrusion 320 thus acts as a gutter to retain liquid in the door 302 to avoid spillage outside of the cooking device 300. When the door 302 moves from the open position to the closed position, the seal 310 rotates toward the cooking chamber 303 and compresses. The result of this rotation is that once the door 302 is closed, as illustrated in FIG. 9, the second side 334 of the protrusion 320 can rest flush against a floor 344 of the cooking chamber 303. In this state, as illustrated by the arrows in FIG. 9, the liquid that has been retained on the first side 332 of the protrusion 320 can flow from the protrusion 320 and across the floor 344 before ultimately pooling in a collection area 311. As illustrated in FIGS. 3-4, the collection area 311 is formed between the door 302 and the floor 344 of the cooking compartment 303 by the housing 306 abutting against the door 302. The collection area 311 can extend along the width of the cooking compartment 303 and parallel to the seal 310 when the door 302 is closed. The liquid in collection area 311 can ultimately be recycled into the cooking process.
