Description

[0001] Cross-reference to related applications

[0002] Based on 35 U.S.C. 119(e), this application claims priority to U.S. Application No. 63 / 512,523, filed July 7, 2023, entitled “Cooking Apparatus, Method and Components thereof,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] A countertop cooking system comprising one or more convection and radiant heating elements combined with a microwave heating element is provided, as well as a method for using the countertop cooking system. Background Technology

[0004] Traditional microwave cooking systems typically include a microwave source (i.e., a magnetron) that directs microwave energy to the food within the cooking compartment. The microwave energy heats the water molecules in the food, converting them into steam. Because traditional microwave units consist only of the microwave source, the air inside is relatively cold, causing condensation to form once the microwaves are no longer being absorbed by the food. This rapid condensation means that moisture remains on the food's surface because there is no means of evaporation to remove the moisture generated during the microwave process, leading to undesirable reheating or cooking results.

[0100] It should be noted that the accompanying drawings are not necessarily drawn to scale. The drawings are intended to depict only typical aspects of the subject matter disclosed herein and should therefore not be considered as a limitation on the scope of this disclosure. Detailed Implementation

[0101] Certain exemplary embodiments will be described herein to provide a general understanding of the principles of the structure, function, manufacture, and use of the apparatuses 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 apparatuses and methods specifically described herein and illustrated in the accompanying drawings are non-limiting exemplary embodiments, and that the scope of this invention is defined only by the claims. Features shown or described in connection with one exemplary embodiment may be combined with features of other embodiments. Such modifications and variations are intended to be included within the scope of this invention.

[0102] Traditional countertop cooking systems, such as air fryers, typically consist of a heating element and a fan positioned above the cooking chamber. Due to the slow nature of convective heat exchange, these types of cooking appliances may require relatively long amounts of time to cook or reheat food. Microwaves can be used to cook or reheat food relatively quickly, creating steam within it, as food absorbs microwaves. However, microwaves can leave food moist because condensation remains on and within the food after cooking. While the basic function of a microwave oven is to heat food via dielectric heating (i.e., via microwaves acting directly and being absorbed by the food), this disclosure includes microwave ovens with additional multiple cooking capabilities, such as a crisping (or browning) function or a grilling function, enabling the preparation of various types of food items and providing new cooking effects. Such additional multiple cooking capabilities typically require additional components, such as a browning plate or a grilling element.

[0103] The embodiments of the cooking systems and methods described herein advantageously provide systems that can be rapidly reheated and / or cooked using microwaves, while also providing crisping and browning functions to remove water vapor generated from food due to the microwave process, thereby producing more satisfactory finished food products.

[0104] Figures 1 to 4 Embodiments of a cooking system 100 according to the subject matter described herein are depicted. In some embodiments, the cooking system 100 may include a housing 102, which includes a cooking volume 104, an inner container 106, an upper volume 108, and a side volume 110. A door 132 may be movably and rotatably configured on the housing 102 to selectively close the cooking volume 104.

[0105] In one aspect, the cooking volume 104 is the main cooking chamber where food is placed for the cooking process. The cooking volume 104 is formed by an inner shell 105 within the housing 102 and can be used as a shield for microwaves and heat, as will be described in more detail below. Air gaps may be positioned around the inner shell 105 and the housing 102 to isolate the cooking volume 104 from the housing 102 in terms of heat transfer.

[0106] Figures 5A to 5CA cross-sectional view of a cooking system 100 is shown, including a cooking volume 104 and a more detailed view of its constituent components. As shown, the cooking volume 104 may include a tray 502 configured to divide the cooking volume 104 into an upper cooking volume 512 and a lower cooking volume 514. In one aspect, a user of the cooking system may expect to place two food items in the cooking volume 104, thus the individual items can be separated using the tray 502. The upper cooking volume 512 may provide a container 106 for the food items. For example, Figure 5B A cooking volume 104 is shown, with the container 106 removed, exposing the upper cooking volume 512. When the container is removed, a fan 130 can provide circulating air throughout the cooking volume 104. In one aspect, when the air circulating from the fan 130 is turned on, the circulating air can reach food placed on the tray 502 and the upper cooking volume 512, as well as food placed in the lower cooking volume 514, which can be cooked evenly.

[0107] The upper surface of the cooking volume 104 is defined by an inner top wall 109. The inner top wall 109 separates the upper volume 108 from the cooking volume 104. The upper volume 108 is disposed within the housing 102 and positioned vertically above the cooking volume 104. The inner top wall 109 includes a plurality of orifices disposed therein and is configured to allow airflow from the upper volume 108 into the cooking volume 104, as described in more detail below. The inner top wall 109 also protects the components within the upper volume 108 from food splashes that may occur during cooking. The inner top wall 109 may be made of a metallic material and may also include a single or multiple orifices 111 configured in a specific pattern to facilitate airflow from the upper volume 108 to the cooking volume 104. The pattern of the orifices 111 may correspond to the size of the opening of the inner container 106, as described in more detail below.

[0108] Figure 2 as well as Figure 6A Figure 7 depicts a perspective view of the side volume 110 of the cooking system 100. The side volume 110 is separated from the cooking volume 114 via a side wall 616. Figure 6A As shown, the side volume 110 may include a magnetron 620 positioned adjacent to the rear wall 604 of the side volume 110. The magnetron 620 is configured to emit electromagnetic waves as a microwave source into the cooking volume 104. To guide microwaves from the magnetron 620 to the cooking volume 104, a waveguide 617 is positioned within the side volume 110. The waveguide 617 is a metal conduit that contains and guides microwaves from the magnetron 620 to the cooking volume 104. In one aspect, the waveguide 617 is positioned on a side wall 616, having an inlet at the magnetron 620 and an outlet at an orifice in the side wall 616.

[0109] like Figure 7A As shown, the orifice of the mode stirrer 702 is located adjacent to the sidewall 616. The mode stirrer 702 is configured to randomly distribute microwaves from the microwave assembly 120 within the cooking volume 104 to ensure uniform heating during microwave cooking. As described in more detail below, the mode stirrer 702 can rotate about a central axis to enhance the distribution of microwave energy throughout the cooking volume 104.

[0110] The modal stirrer 702 may be circular, flat in a single plane, or include curved protrusions extending axially from the plane of rotation. In one aspect, the modal stirrer may include a first slot 704 and a second slot 706, wherein the first slot 704 and the second slot 706 are configured to randomly scatter microwaves from the magnetron 620 throughout the cooking volume 104. The slots 704, 706 may be rectangular in shape and include protrusions extending axially from the edges of the slots 704, 706 into the cooking volume 104.

[0111] like Figure 7B As shown, a mode stirrer 702 is connected via a waveguide 614 to a motor 710 positioned within the side volume 110. A drive shaft extends through the waveguide 614 and is non-rotatably connected to the mode stirrer 702 to transfer rotational motion from the motor 710 to the mode stirrer 704. In one aspect, the mode stirrer 702 can rotate continuously during a cooking mode in which the microwave assembly 120 is operating and emitting microwaves into the cooking volume 104. In another aspect, the mode stirrer 702 can rotate at a single speed during cooking operation. Furthermore, in another aspect, the mode stirrer 702 can change its rotational speed according to the cooking process. Figure 6B As shown, the mode stirrer is positioned on the side wall 616 behind the mica sheet 614. The mica sheet 614 allows microwaves to pass through and enter the cooking volume 104 while concealing the mode stirrer 702 from the user's view.

[0112] When the cooking process is underway, heat is generated within the side volume 110 due to the magnetron 620 and motor 405 disposed therein. To help dissipate excess heat within the side volume 110, the side volume 110 may include a fan 608 powered by a motor 609, positioned on the top wall 606. Furthermore, the motor 405 includes the fan 606. Figure 6B As further shown, the side volume 110 may include a sidewall 616 with ventilation holes 618.

[0113] Arranged in the upper volume 108 is an air movement device 130 (i.e., a fan). The air movement device 130 is configured to generate airflow into the cooking volume 104 during convection heating. In one aspect, the air movement device 130 may be a radial fan that generates radially outward airflow. Figure 3A As shown, the fan 130 inside the upper volume 108 can be surrounded by a reflector cover 302. When the fan 130 is turned on, the reflector cover 302 can redirect the radial airflow from the fan and guide it downward through the orifice 111 of the inner top wall 109 and into the cooking volume 104.

[0114] The air movement device 130 can be connected to the drive system 304 to power the air movement device 103, while reducing the height of the housing 102 compared to a conventional air fryer. Figure 3B As shown, the drive system 304 can be connected at a first point in the upper volume 108 and at a second point in the side volume 110. Figure 4 A perspective view of a belt drive system 304 configured to circulate air within container 106 is depicted. At a first point A on the upper volume 108, belt 310 can be connected to a first gear 402 or pulley. At a second point B on the side volume 110, belt 310 can be connected to a second gear 404 or pulley. The first gear 402 and the second gear 404 can be designed with components for achieving speed matching between the motor 405 and the respective gears 402, 404. For example, the first gear 402 and the second gear 404 can be configured to have the same diameter to achieve a 1:1 gear ratio during fan operation. This configuration provides minimal power loss when operating the cooking system 100. Furthermore, this direct drive configuration achieves minimal noise from the fan 130 and therefore the motor, which will be described in more detail below. However, different gear ratios can be used between gears 402, 404, and should be considered within the scope of this disclosure. In one aspect, gears 402, 404 may include gear teeth positioned on the peripheral edges of the respective gears. Furthermore, belt 310 may include corresponding teeth that mesh with the teeth of gears 402, 404 to help prevent belt 310 from slipping relative to gears 402, 402 during operation.

[0115] Gear 402 is connected to fan 130 via a drive shaft extending vertically downward through the inner shell of cooking volume 104. Belt 310 is configured to drive the rotation of fan 130 and generate air circulation within the container. In one aspect, belt 310 may be made of synthetic rubber to extend the service life of cooking system 100. For example, since the cooking system may operate at high temperatures, belt may be made of urethane and polyurethane, polyvinyl chloride, or nylon fibers. In one aspect, a gear train or multiple gears may be used instead of belt.

[0116] To generate a heated airflow for the convection cooking process, a heating element 140 is positioned adjacent to a fan 130 to heat the airflow generated by the fan 130. The heat source 140 can be a radiant or convective heat source, and in combination with the fan 130, can generate a heated airflow capable of traveling from the upper volume 108 to the cooking volumes 104, 114. In one aspect, the heating element 140 is a cal-rod, tungsten alloy, carbon fiber, or any other suitable heat source. In one aspect, the heating element 140 can be positioned in the same horizontal plane around the fan 130 and radially offset from the fan 130. In one aspect, the heating element 130 can be cyclically turned on and off during cooking depending on the desired temperature or cooking method (i.e., air frying, baking, roasting).

[0117] Depending on the size of the food item and therefore the choice of using container 106 and heating element 140 or cooking volume 104 and microwave unit 120, the cooking system 100 can adapt to the user's choice. For example, when food is placed in container 106, the cooking system 100 can activate heating element 140 independently of microwave unit 120, and vice versa. As will be described in more detail below, if the user expects to heat food via container 106, the cooking system 100 can deactivate microwave unit 120 to conserve energy used by the cooking system 100 during operation.

[0118] The inner container 106 may also include a cooking volume 114 where food can be positioned to receive microwave, radiant, and / or convective heat. In one aspect, the container 106 may be a metal, glass, or suitable polymer that allows microwaves to pass through. The container 106 may be held on the top inner surface of the cooking volume 104 by a support 123 having a channel 124 extending downward from the inner top wall 109. Figure 5C As shown, when container 106 is placed inside the upper cooking volume 512, container 106 is positioned directly adjacent to fan 130 and heating element 140. Due to this proximity, airflow from fan 130 and heating element 104 is essentially contained within container 106, as indicated by airflow AF. This also prevents excessive heated airflow from reaching the lower cooking volume 514. In one aspect, this allows heat generated by heating element 140 to be retained within the cooking volume of container 106. For example, as container 106 is placed inside the upper cooking volume, channel 124 provides support for the container through the outer lip 516 of container 106. See also Figure 5C and Figure 5D The outer lip 516 can be shown resting against the channel 124. In one aspect, the support provided by the channel 124 can serve as a guide when the container 106 is placed inside the upper cooking volume 512. In some embodiments, such as Figure 5D As shown, when container 106 is placed inside the upper cooking volume 512, outlet 520 can be positioned between the outer lip 516 and the channel 124. Outlet 520 allows ventilation of cooking volume 114 during convection cooking. For example, during operation of cooking system 100, as fan 130 circulates air around container 106, the internal temperature and pressure within container 106 will increase. Outlet 520 provides sufficient space for hot air to exit container 106 and enter cooking volume 104. Because most of the heated airflow remains within cooking volume 114, this helps increase the operating efficiency of the convection cooking process.

[0119] Because the cooking apparatus 100 combines a convection cooking system and a microwave cooking system, multiple cooking processes can be performed within the apparatus. A first cooking process may include heating food within the cooking volume 104 using only microwaves. Furthermore, a second cooking process may include generating convection airflow to further heat and cook the food within the cooking volumes 104 and 114. The container 106 and the cooking volume 114 may be designed with optimal volumes to enhance the cooking process during operation. In one aspect, the container 106 may be configured to have an internal volume ranging from 0.10 cubic feet to 0.15 cubic feet, specifically 0.13 cubic feet. In another aspect, the container 106 may be configured to have an internal volume ranging from 0.18 cubic feet to 0.22 cubic feet, specifically 0.20 cubic feet. As the fan 130 circulates hot air from the heating element 140 into the container 106, the heat concentration can increase at a faster rate within the volume 114 compared to the cooking volume 104 due to the smaller size of the volume 114. In one aspect, the cooking volume 104 may be configured to have an internal volume in the range of 0.70 cubic feet to 0.90 cubic feet, specifically 0.80 cubic feet. In another aspect, the cooking volume 104 may be configured to have an internal volume in the range of 1.0 cubic feet to 1.2 cubic feet, specifically 1.1 cubic feet. In one aspect, the ratio of the cooking volume 104 to the volume 114 is in the range of 5.3:1 to 6.3:1. Specifically, this ratio may be 5.50:1 or 6.15:1.
