DETAILED DESCRIPTION OF THE INVENTION

[0022] The invention will now be described with reference to the drawing figures, in which like reference numerals refer to like parts throughout. For purposes of clarity in illustrating the characteristics of the present invention, proportional relationships of the elements have not necessarily been maintained in the drawing figures. It will be understood that any dimensions included in the figures are simply provided as examples and dimensions other than those provided therein are also within the scope of the invention.

[0023] The description of the invention references specific embodiments in which the invention can be practiced. The embodiments are intended to describe aspects of the invention in sufficient detail to enable those skilled in the art to practice the invention. Other embodiments can be utilized and changes can be made without departing from the scope of the present invention. The present invention is defined by the appended claims and the description is, therefore, not to be taken in a limiting sense and shall not limit the scope of equivalents to which such claims are entitled.

[0024] FIGS. 1 and 2 depict a lid member 1 and a vessel 5 that together may perform at least two cooking functions. Such cooking functions may be carried out in association with a number of different types of food products. More particularly, the lid member 1 may be selectively attachable to the vessel 5, and together they may be used as an air fryer or pressure cooker. Each of the lid member 1 and the vessel 5 may include a number of components that are known in the art. For example, the lid member 1 includes a first electrical attachment 10, and the vessel 5 includes a second electrical attachment 15. The electrical attachments 10, 15 preferably provide electrical communication between the lid member 1 and the vessel 5 when they are aligned with one another and further mated with one another.

[0025] The vessel 5 also preferably includes a control panel 20. The control panel 20 may serve as a means by which a user may input or otherwise select cooking modes. The control panel 20 may, for example, instruct the lid member 1 to carry out the below described mechanical operations to prepare the lid member 1 (and the vessel 5) to air fry or pressure cook food contained in the vessel 5.

[0026] In FIGS. 1 and 2, the lid member 1 and the vessel 5 each include a casing 25 that keeps internal components covered. The casing 25 thus may protect components within the lid member 1 and the vessel 5 from operator error or errant debris. In a preferred embodiment, the casing 25 is constructed from a metal such as stainless steel, but may also be made from a material such as those known in the art such as plastic or the like to give the lid member 1 a more finished appearance. The lid member 1 is illustrated in FIGS. 3-8 without the casing 25 to better illustrate the various mechanical components within the lid member 1.

[0027] As illustrated in FIG. 3, the lid member 1 preferably includes a slider member 30 at an upper portion 35 thereof. The slider member 30 is preferably seated within a slot member 40 that allows the slider member 30 to slide from side to side within the slot member 40. The slider member 30 may be provided in a multitude of shapes or sizes, or it may be provided as an alternative activation member like those known in the art such as a handle, knob, button, or otherwise. The slider member 30 preferably acts as an activation member that sets into motion the various components described below that put the lid member 1 and the vessel 5 in condition to carry out its air frying or pressure cooking operations. In the embodiment illustrated in FIG. 3, the lid member 1 is in position to carry out the air frying function.

[0028] Below the slider member 30, the slider member 30 is preferably in mechanical connection with a first linear gear 45. The first linear gear 45 is a rack of a rack and pinion actuator that includes gear teeth 50 for engaging the gear teeth of a pinion (described below). In some embodiments, the first linear gear 45 and the slider member 30 may be integrally formed with one another. When a user slides the slider member 30 so that it slides within the slot member 40, the first linear gear 45 thus also slides/translates from side to side.

[0029] A circular gear 55 including gear teeth 60 is preferably in mechanical connection with the first linear gear 45. The circular gear 55 acts as the pinion in the rack and pinion system that the first linear gear 45 and the circular gear 55 represent. When the linear gear 45 translates, its gear teeth 50 engage the gear teeth 60 in the circular gear 55. The teeth 50, 60 work to convert the linear movement of the linear gear 45 into the circular rotational movement of the circular gear 55. More particularly, in the illustrated embodiment, as the slider member 30, and thus the first linear gear 45, move to the right, the circular gear 55 rotates in a clockwise direction.

[0030] The circular gear 55 is also in mechanical connection with a second linear gear 65 including gear teeth 70. The second linear gear 65 makes up a side portion 75 of a clamp member 80 that may secure (and unsecure) the lid member 1 to the vessel 5. When the circular gear 55 rotates as a function of the first linear gear 45 translating, the second linear gear 65 also translates. This not only causes the second linear 65 to translate inwardly, but also the clamp member 80 itself.

[0031] The clamp member 80 is preferably C-shaped so that they may clamp the lid member 1 to an upper portion of the vessel 5. The clamp member 80 may translate radially inwardly and outwardly so as to get closer to, and farther from, the vessel 5 as a user slides the slider member 30.

[0032] More particularly, when the clamp member 80 is drawn inwardly by pushing the slider mechanism to the right in the illustrated embodiment, it is drawn away from a lip member 85 provided around a circumference of the vessel 5. The clamp member 80 includes a foot member 90 at its lower portion that protrudes outwardly therefrom. As set forth below, when the lid member 1 is set to be in its pressure cooking mode, the foot member 90 may be positioned under the lip member 85 so that the lid member 1 may not be removed from the vessel 5.

[0033] It should be noted that in the embodiment illustrated herein, the lid member 1 includes two clamp members 80 on substantially opposite side of the lid member 1 from one another. As such, the lid member 1 also includes two first linear gears 45 (the second of which is obscured from view on FIG. 3), circular gears 55, and second linear gears 65. Preferably, the slider member is also in mechanical connection with the first linear gear 45 on the opposite side of the lid member 1. When the slider member 30 is moved to the right, both of the first linear gears 45 translate to the right and set into motion the above-described actions that ultimately result in the clamp members 80 drawn inwardly. In alternative embodiments, more or fewer clamp members 80, and gears 45, 55, 65, may be provided. In the embodiment described herein, the number of clamp members 55 and the number of respective gears 45, 55, 65, 35 are equal to one another.

[0034] In the first position illustrated in FIGS. 3 and 4, with the firm attachment between the lid member 1 and the vessel 5 eliminated, air communication between the vessel 5 and the environment is created to help facilitate the air frying process. On an underside 95 of the lid member 1, a fan 100 is provided that helps circulate the air used during air frying.

[0035] Turning to FIG. 5, the lid member 1 is shown in a transitional phase between its air frying and pressure cooking positions. More particularly, in FIG. 5, the slider member 30 is shown as having been translated at partially to the left within the slot member 40. As such, the first linear gear 45 has similarly been translated to the left, the circular gear 55 has rotated in the counterclockwise direction, and the second linear gear 65 and thus the clamp members 80 are translated radially outwardly so that their foot members 90 partially, but not completely, extend below the lip member 85 of the vessel 5. As such, in this position, the lid member 1 is secured to the vessel 5, but not secure that an airtight seal is formed capable of withstanding the pressures created by a pressure cooking operation.

[0036] When the lid member 1 and vessel 5 are pressure cooking food within the vessel 5, the food may have a tendency to splatter as it is heated up. As such, the lid member 1 is preferably provided with a cap member 105 that is releasably attachable to the underside 95 of the lid member 1 to cover the fan 100. In FIG. 6, the cap member 105 is illustrated as attached to the underside 95 of the lid member 1 to protect the fan 100 from splatter. The cap member 105 may be attached to the lid member 1 in a number of ways, including but not limited to a mechanical connection like tabs or a friction fit, or even magnets. The cap member 105 is not required for the lid member 1 to operate, but it may help to maintain the fan 100 in working order while the lid member 1 is used to pressure cook food contained therein.

[0037] FIGS. 7 and 8 illustrate the lid member 1 in its pressure cooking position. In the pressure cooking position, the slider member 30 has been translated further or even completely to the left within the slot member 40. As described above, since the slider member has translated to the left, the first linear gear 45 has similarly been translated to the left. The circular gear 55 has further rotated in the counterclockwise direction, and the second linear gear 65 has translated outwardly, along with its associated clamp member 80 and its foot member 90. In this position, the foot member 90 has extended outwardly even farther below the lip member 85 of the vessel 5. In this position, the foot member 90 of the clamp member 80 is firmly secured below the lip member 85, thus securing the lid member 1 to the vessel 5 in an airtight manner. The clamp member 80 and its associated gear members 45, 55, 65 on the opposite end of the lid member from the illustrated clamp member 80 may operate similarly. In this position, because the seal between the vessel 5 and the lid member 1 is airtight, pressure cooking may be carried out.

[0038] When the lid member 1 and the vessel 5 are in its pressure cooking position, like other pressure cookers, the lid member 1 may include each of an indicator 110 and a through-hole 115. In operation, the indicator 110 is preferably in fluid communication with the inside of the vessel 5. The indicator 110 is preferably formed as a cylindrical tab that pops up when pressure is reached in the vessel 5. Such pressure may only be produced in the vessel 5 when the lid member 1 works with the vessel 5 to carry out its pressure cooking function. When the lid member 1 and the vessel 5 are in the pressure-cooking mode, with the slide member 30 slid to the left, and the clamp members 80 pushed outwardly, the indicator 110 may protrude through the through hole 115 when pressure is reached in the vessel 5.

[0039] Sensors may also be located in the lid member 1 or the vessel 5 that are able to detect when the lid member 1 is in the pressure cooking or air frying mode. The sensors may be in communication with a microcontroller that may instruct the lid member 1 to carry out particular functions associated with pressure cooking or air frying, depending on the position of the slider member 30, user input, or both.

[0040] From the foregoing, it will be seen that the various embodiments of the present invention are well adapted to attain all the objectives and advantages hereinabove set forth together with still other advantages which are obvious and which are inherent to the present structures. It will be understood that certain features and sub-combinations of the present embodiments are of utility and may be employed without reference to other features and sub-combinations.
