DETAILED DESCRIPTION OF THE INVENTION
(15) 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.
(16) 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.

(18) As illustrated in
(19) At a lower portion 20 of the dial member 15, a plate member 25 is also in mechanical connection with the handle 5, or may be connected to the handle 5 regardless of the dial member 15. As such, when the handle 5 and/or the dial member 15 are rotated, the plate member 25 is similarly rotated. In at least one embodiment, the handle 5, dial member 15, and plate member 25 may be integrally formed. However, in other embodiments, they may be separately constructed and in mechanical connection with one another via known or foreseeable methods and mechanisms.
(20) Near an outer edge 30 of the plate member 25, the plate member 25 may include a plurality of slot members 35. In the embodiment described herein, the plate member 25 includes four slot members 35. However, in alternative embodiments, more or fewer slot members substantially similar to the slot members 35 may be associated with the plate member 25. The slot members 35 may generally be formed as elongated, slightly curved apertures in the plate member 25.
(21) Each slot member 35 preferably includes each of a first end 40 and a second end 45. In a preferred embodiment, the first end 40 is closer to the outer edge 30 of the plate member 25, while the second end 45 is closer to an inner edge 50 of the plate member 25. Between the first end 40 and the second end 45, the aperture formed by the slot member 35 preferably gets closer to the inner edge 50. This creates a ramping, or cam, effect by the slot members 35.
(22) The lid member 1 also preferably includes a plurality of clamp members 55 located along an outer periphery thereof. The clamp members 55 are preferably C-shaped so that they may clamp the lid member 1 to an upper portion of a vessel. The clamp members 55 may be attached to the plate member 25, or in alternative embodiments, to another portion of the dial member 15. The clamp members 55 are preferably attached to the plate member 25 or the dial member 15 in such a manner that allows the clamp members 55 to translate radially inwardly and outwardly so as to get closer to, and farther from, the vessel. As will be described in greater detail herein below, the clamp members 55 are preferably able to translate inwardly or outwardly as the handle 5 and/or dial member 15 is rotated. In the embodiment illustrated herein, the lid member 1 includes four clamp members 55, the same number as slot members 35 that are provided. However, like the slot members 35, in alternative embodiments, more or fewer clamp members 55 may be provided. In the embodiment described herein, the number of clamp members 55 and the number of slot members 35 should be equal to one another.
(23) A pin 60 that is integrally formed with the clamp member 55 preferably projects upwardly therefrom. In operation, each pin 60 is received within a distinct slot member 35. This is preferably true for each clamp member 55, pin 60, and slot member 35 of the lid member 1. As will be described below, it is the rotation of the dial member 15 and its slot members 35 that act as cams on the pin members 60, and in turn the clamp members 55, to radially translate the clamp members 55 inwardly or outwardly to clamp or unclamp the lid member 1 to the vessel.
(24) With the pin members 60 positioned and located within the slot members 35, rotation of the handle 5, dial member 15, and/or the plate member 25 may cause radial translation of the clamp members 55. As illustrated in
(25) In the position illustrated in
(26)
(27) As one skilled in the art can appreciate, in order for a lid such as the lid member 1 and a vessel to carry out pressure cooking operations, the vessel should be air tight. As such, in addition to the lid member 1 being securely coupled to the vessel via the clamp members 55, communication between the vessel and the environment must be eliminated. To do so during the pressure cooking process, an internal sealing mechanism 85 may be used. Generally, the internal sealing mechanism 85 may comprise a plurality of panel members 90 in mechanical connection with the handle 5 and a sealing plate 95. The sealing plate 95 preferably includes a plurality of sealing apertures 100 that may be selectively covered by the panel members 90 (as illustrated in
(28) As illustrated and described in reference to
(29) A lower face 105 of the sealing plate 95 may be provided with a plurality of nub members 110. The nub members 110 may be small cylindrical projections that extend downwardly from the lower face 105. The nub members 110 may be useful for molding purposes, but are not a critical part of the lid member 1 and may be omitted in certain embodiments.
(30) Turning to
(31) As illustrated in
(32) In operation, the handle 5 and the dial member 15 (and plate member 25) may be rotated to a variety of degrees to place the pin 60 at various positions along the length of the slot members 35. Similarly, the clamp members 55 may be positioned near or farther from the outer circumference 125 of the lid member 1 depending on the position of the pin members 60 within the slot members 35 at a number of locations. As illustrated in
(33) Turning to
(34) To transition the sealing plate 95 from a position in which the panel members 90 are seated within the sealing apertures 100 to the position illustrated in
(35)
(36) When the handle 5 is rotated in the manner described above with reference to
(37) As described above with reference to
(38)
(39) Also illustrated in
(40) Furthermore, like lid members and vessels known in the art, the lid member 1 and the vessel 135 may include components that help to carry out the pressure cooking or air frying functions of the lid member 1 and the vessel 135. For example, as illustrated in
(41) Along a central portion of the lid member 1, a shaft 155 is preferably provided that connects the handle 5 to the sealing plate 95. As such, when the handle 5 is rotated, so too is the shaft 155 and the sealing plate 95 associated therewith. Similarly, when the handle 5 is pushed downwardly, the shaft 155 and the sealing plate 95 is translated downwardly, and when the handle 5 is translated upwardly, the sealing plate 95 is translated upwardly for the same reasons.
(42) As illustrated in greater detail in
(43) Sensors may also be located in the lid member 1 or the vessel 135 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 to carry out particular functions associated with pressure cooking or air frying, depending on the position of the handle, user input, or both.
(44) In an alternative embodiment, the lid member 1 may be reconfigured to be a simplified component. More particularly, the lid member 1 may be adapted for an appliance that may not have a pressure cooking mode, but does have an air frying mode and at least one other conductive cooking (e.g., slow cook, warming) mode. The alternatively constructed appliance, which is not illustrated in its entirety, also only includes one lid, but the lid may not form an airtight seal with vessel when it is not used as a pressure cooker.
(45) The simplified appliance preferably includes a cover member 165 (illustrated in
(46) The cover member 165 may include each of a first cover portion 170 and a second cover portion 175. In the illustrated embodiment, the first cover portion 170 may be fixedly attached to an underside of the lid member 1 via bolt holes 180 (see
(47) The first cover portion 170 preferably includes apertures 190 (see
(48) The second cover portion 175 is preferably coupled to the first cover portion 170 such that it is movable (preferably rotatable) relative to the first cover portion 170. The second cover portion 175 preferably includes apertures 195 (see
(49) When a user wishes to operate the appliance in its air frying mode, there should be air communication between the fan and heating element of the lid 165 and the contents of the vessel 135. As such, the apertures 190, 195 should be aligned with one another so that air may pass therethrough. To align the apertures 190, 195 to allow air to pass through them, a user may simply use the tab member 200 to rotate the second cover portion 175 until the apertures 190, 195 are substantially aligned, as illustrated in
(50) Turning to
(51) Because of the simplicity that the cover member 165 provides to the appliance, certain components used when the appliance has a pressure-cooking function are not necessary. For example, the appliance using the cover member 165 does not require an exterior handle or a mechanism that creates an airtight seal between the lid member 165 and the vessel 135.
(52) 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. Since many possible embodiments of the present invention may be made without departing from the spirit and scope of the present invention, it is also to be understood that all disclosures herein set forth or illustrated in the accompanying drawings are to be interpreted as illustrative only and not limiting. The various constructions described above and illustrated in the drawings are presented by way of example only and are not intended to limit the concepts, principles and scope of the present invention.
(53) Many changes, modifications, variations and other uses and applications of the present invention will, however, become apparent to those skilled in the art after considering the specification and the accompanying drawings. All such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention which is limited only by the claims which follow.
