Consumers are continually looking for ways to make quality food at home while reducing the amount of time that it takes to prepare and cook the food. There is currently a trend to make healthy fast food at home. Recent examples of appliances that achieve this include electric pressure cookers and air fryers. Moreover, as people add a greater variety of cooking appliances into their home, space becomes an issue. Thus, there is a continued need in the industry for cooking appliances that have a small footprint, are easy to use, and can make high quality and good tasting food quickly while also being simple to clean after use.
Exemplary embodiments according to the present disclosure are directed to a cooking apparatus for cooking a food item. The cooking apparatus may include a base component and a lid component. The base component includes a reservoir. The lid component may be alterable between a closed state whereby the lid closes an open top end of the reservoir and an open state whereby the reservoir is exposed. A plurality of cups may be positioned in the reservoir of the base component. Each of the cups may have an internal cavity with a first liquid holding capacity. The reservoir of the base component may have a second liquid holding capacity when the plurality of cups are positioned in the reservoir. The second liquid holding capacity is equal to or greater than the first liquid holding capacity so that one of the cups can be filled with liquid and then the liquid poured from the cup into the reservoir without overflowing the reservoir.

As noted above, in the exemplified embodiment the lid component 200 is pivotably coupled to the base component 110. Specifically, the lid component 200 is coupled to the base component 110 by a hinge mechanism 101. Thus, altering the lid component 200 from the closed state to the open state and from the open state to the closed state comprises rotating the lid component 200 relative to the base component 110 about an axis A-A. Thus, in the exemplified embodiment the lid component 200 remains attached to the base component 110 in both the open state and the closed state as well as while it is rotating between the open and closed states. However, the invention is not to be so limited in all embodiments and in other embodiments the lid component 200 may be separate and distinct from the base component 110 when in the open state and then the lid component 200 may be placed onto and coupled to the base component 110 when in the closed state.
The cooking apparatus 100 also comprises a locking mechanism 102 for locking the lid component 200 in the closed state. In the exemplified embodiment, the base component 110 comprises a first locking member 111 and the lid component 200 comprises a second locking member 201, with the first and second locking members 111, 201 collectively forming the locking mechanism 102. In the exemplified embodiment, the first locking member 111 is a tab element 112 protruding from an outer surface of the base component 110. Furthermore, the second locking member 201 is a latch element 202 comprising an arm member 203 extending downwardly from the lid component 200 and a catch member 204 extending from the arm member 203. The latch element 202 is pivotably coupled to the lid component 200 such that actuation of the latch element 202 may be needed to alter the lid component 200 from the closed state to the open state.
Specifically, when altering the lid component 200 from the open state to the closed state, the latch element 202 will automatically flex outwardly as the catch member 204 passes over the tab element 112. Then, once the catch member 204 has slid past the tab element 112, the latch element 202 will flex back to its original, natural position in which the catch member 204 will engage an underside of the tab element 112. This engagement between the catch member 204 and the tab element 112, as shown in
The lid component 200 comprises a shell component 210 and a heating component 220. More specifically, the shell component 210 comprises an outer surface 211 that forms a portion of an exposed outer surface of the cooking apparatus 100 and an inner surface 212 opposite the outer surface 211. The inner surface 212 defines a cavity and the heating component 220 is positioned at least partially within the cavity. The shell component 210 may be formed of plastic or a metal with a low heat conductivity so that heat generated by the cooking apparatus 100 is only minimally transferred to the outer surface 211 of the shell component 210 to prevent a user from getting burned when touching the shell component 210 during use of the cooking apparatus 100.
The heating component 220 comprises a heating plate 221 and one or more heating elements 228 coupled to the heating plate 221. The heating plate 221 is coupled to the shell component 210 so that the heating component 220 and the shell component 210 are fixed together. The heating plate 221 may be coupled to the shell component 210 using fasteners such as screws or using adhesive, welding, mechanical engagement, interference or friction fit, or the like. Regardless of the manner in which the heating plate 221 is coupled to the shell component 210, because the heating plate 221 is fixed to the shell component 210, pivoting the lid component 200 between the open and closed states causes the shell component 210 and the heating component 220 to pivot together. The heating plate 221 may be formed from a material, such as a metal, with a high thermal conductivity. For example, in some embodiments the heating plate 221 may be formed from aluminum, although the invention is not to be so limited in all embodiments and other materials such as copper, iron, brass, stainless steel, or the like may be used. Furthermore, the heating plate 221 may be coated with a polytetrafluoroethylene (PTFE) so that the heating plate 221 is a non-stick surface. In other embodiments, the heating plate 221 may be formed from or coated with anodized aluminum, ceramics, silicone, enameled cast iron, or the like for purposes of making it a non-stick surface.
The heating plate 221 comprises an outer surface 222 that faces the shell component 210 and an inner surface 223 opposite the outer surface 222. The inner surface 223 of the heating plate 221 comprises a floor 224 and a sidewall 225 that collectively define a recessed portion 226 of the lid component 200. The outer surface 222 of the heating plate 221 comprises a plurality of channels 227, each of which is configured to receive one of the heating elements 228 therein. Although the heating elements 228 are disposed within channels 227 on the outer surface 222 of the heating plate 221 in the exemplified embodiment, the invention is not to be so limited and the heating elements 228 may be coupled to the heating plate 221 using other techniques in other embodiments. In the exemplified embodiment, the heating elements 228 are in surface contact with the outer surface 222 of the heating plate 221. Thus, when the heating elements 228 are powered, the heat generated by the heating elements 228 is transferred to the heating plate 221 due to thermal conductivity. Thus, as noted above, it is preferable that the heating plate 221 be formed from a material having a high thermal conductivity such as copper, aluminum, brass, or the like to ensure that the heating plate 221 heats up as the heating elements 228 are powered and begin to generate heat.
The lid component 200 also comprises a light indicator 230. The light indicator 230 comprises a light source 231 and a light transmissive cover 232 overlying the light source 231. Thus, when activated the light source 231 emits light that passes through the light transmissive cover 232. The light transmissive cover 232 may be fully transparent or it may be translucent and it may have a color for aesthetic enhancement. Additional details about the functionality of the light indicator 230 will be provided below with reference to
Similar to the lid component 200, in the exemplified embodiment the base component 110 comprises a shell component 120 and a heating component 130. The shell component 120 may be formed of a plastic material or any of the materials noted above with reference to the shell component 210. The shell component 120 comprises an outer surface 121 that forms a part of an exposed outer surface of the cooking apparatus 100 and an inner surface 122 opposite the outer surface 121. The inner surface 122 of the shell component 120 defines an interior space within which the heating component 130 is positioned. In the exemplified embodiment, the shell component 120 comprises a plurality of support legs 129 extending from a bottom thereof for supporting the cooking apparatus 100 on a horizontal surface such as a countertop or the like while elevating the bottom of the shell component 120 relative to the horizontal surface. This may prevent burning the horizontal surface in case the shell component 120 gets hot during operation of the cooking appliance 100.
The heating component 130 is fixedly coupled to the shell component 120 in the exemplified embodiment. This may be achieved using fasteners, screws, adhesive, welding, interference fit, friction fit, mechanical engagement, interlocking features, or the like in various different embodiments. Furthermore, the heating component 130 comprises a heating plate 131 and one or more heating elements 132 that are coupled to the heating plate 131. The heating plate 131 may be formed of any of the materials described above for the heating plate 221 of the lid component 200. Thus, for example, the heating plate 131 may be formed from aluminum, brass, copper, iron, or other materials with a high thermal conductivity so that heat generated by the heating element 132 will heat the heating plate 131 as described herein. The heating plate 131 comprises an inner surface 133 and an outer surface 134, with the outer surface 134 facing the shell component 120. In the exemplified embodiment, the heating plate 131 comprises a plurality of channels 135 formed therein, and one of the heating elements 132 is disposed within each of the channels 135 to couple the heating elements 132 to the heating plate 131. Of course, the heating elements 132 may be coupled to the heating plate 131 in other ways and using other techniques in other embodiments. The heating elements 132 may be in contact with the heating plate 131 so that heat generated by the heating elements 132 heats the heating plate 131 via thermal conductivity.
The inner surface 133 of the heating plate 131 comprises a floor 136 and a sidewall 137 that collectively define a reservoir 140 of the base component 110. The reservoir 140 of the base component 110 has an open top end 141 that is closed when the lid component 200 is in the closed state, as shown in
As shown in
When the cooking apparatus 100 is assembled as shown in the drawings, the heating elements 228, 132 and the outer surfaces 222, 134 of the heating plates 131, 221 are not visible or exposed. Rather, with the lid in the open state as shown in
Referring to
In the exemplified embodiment, each of the cups 300 has a first liquid holding capacity, which is an amount of a liquid that can be placed into the internal cavity 315 of the cup 300 without the liquid overflowing the internal cavity 315 of the cup 300 and pouring out of an open top end 316 of the internal cavity 315. Stated another way, the internal cavity 315 of each of the cups 300 has a first volume. As will be described in detail with reference to
The cups 300 comprise a closed bottom end 303 and a top end 304 which forms the open top end 316 of the internal cavity 315. Furthermore, the cups 300 comprise one or more support members 330 extending from the closed bottom end 303. In the exemplified embodiment, there are a plurality of the support members 330 arranged in a circumferentially spaced apart manner about a loop or loop configuration. Thus, in the exemplified embodiment each of the support members 330 is a protuberance having an arcuate shape that extends from the closed bottom end 303 of the cup 300. When the cups 300 are positioned in the reservoir 140 of the base component 110 as shown in
The reservoir 140 of the base component 110 is sized and configured so that four of the cups 300 can be positioned therein at one time. Specifically, as shown in
The cups 300 have an outer diameter OD1 and a height H1 measured from a distal-most end of the support members 330 to the top end 304. In the exemplified embodiment, a ratio of the outer diameter OD1 to the height H1 is at least 2:1. In some embodiments, the ratio of the outer diameter OD1 to the height H1 is approximately 2:1 (i.e., between 1.9:1 and 2.1:1). Thus, the cups 300 are approximately twice as wide as they are tall.
In the exemplified embodiment, the height H1 of the cups 300 is greater than a depth D1 of the reservoir 140 of the base component 110 measured from the floor 136 of the reservoir 140 to the open top end 141. As a result, the cups 300 protrude from the open top end 141 of the reservoir 140 when positioned in the reservoir 140 with the support members 330 in contact with the floor 136 of the reservoir 140. Thus, when the cups 300 are positioned in the reservoir 140, a first portion 335 of the cups 300 is located within the reservoir 140 between the open top end 141 and the floor 136 and a second portion 336 of the cups 300 protrudes from the open top end 141 of the reservoir 140. When the lid component 200 is in the closed state, the second portion 336 of the cups 300 extend into the recessed portion 226 of the lid component 200. Thus, the reference plane RP1-RP1 on which the open top end 141 of the reservoir 140 and the lid-to-base interface LBI lie intersects the cups 300. Furthermore, when the lid component 200 is in the closed state, the floor 224 of the heating plate 221 of the heating component 220 of the lid component 200 is spaced from the top end 304 of the cups 300 by a gap so that the lid component 200 does not contact the cups 300 and distort them in any way. Thus, the height of the cooking cavity 150 is greater than the height H1 of the cups 300.
In the exemplified embodiment, the handle portion 320 of the cups 300 does not extend the full height of the cups 300. Rather, the handle portion 320 extends from a top edge 321 that is flush with the top end 304 of the body portion 310 of the cups 300 to a bottom edge 322 that is located between the top end 304 and the closed bottom end 303 of the cups 300. The handle portion 320 may have a length L1 measured from the top edge 321 to the bottom edge 322 with the length L1 being less than the height H1 of the cups but greater than one-half of the height H1 of the cups 300. The handle portion 320 may extend the full height of the cups 300 in alternative embodiments. In some embodiments a ratio of the height H1 of the cups 300 to the length L1 of the handle portion 320 may be between 1.4:1 and 1.7:1.
By having the handle portion 320 extend greater than one-half of the height H1 of the cups 300, a first portion 323 of the handle portion 320 is located in the reservoir 140 of the base component 110 and a second portion 324 of the handle portion 320 is located in the recessed portion 226 of the lid component 110. Stated another way, the plane RP1 on which the open top end 141 of the reservoir 140 and on which the lid-to-base interface LBI lie intersects the handle portion 320 of each of the cups 300.
The benefit of this is two-fold. First, it ensures that the second portion 324 of the handle portion 320 protrudes above a top edge 138 of the sidewall 137 of the reservoir 140, thereby making it available to be grasped by a user without the user having to place his/her fingers into the reservoir 140. This will prevent the user from getting burned by the heating plate 131 when the user is removing the cups 300 from the reservoir 140 after cooking the food items contained therein. Second, by having the first portion 323 of the handle portion 320 located below the top edge of the sidewall 137 and therefore located within the reservoir 140, it ensures that the handle portion 320 will not protrude beyond the inner surface of the sidewall 137 so long as the support members 330 are in contact with the floor 136 of the reservoir 140. Specifically, if the entire handle portion 320 was located above the top edge of the sidewall 137, then the handle portion 320 would extend outwardly beyond the sidewall 137 if the cup 300 were placed too close to the sidewall 137. This would cause the lid component 200 to contact the handle portion 320 when being closed, thereby preventing the lid component 200 from being easily altered into the closed state. By having the first portion 323 of the handle portion 320 located in the reservoir 340, the handle portion 320 will abut the sidewall 137 but will not protrude beyond the sidewall 137 in a radial direction relative to a vertical axis B-B that intersects the base component 110, the lid component 200, and the cooking cavity 150. Thus, as long as the support members 330 (or the bottom end 303) of the cups 300 are in contact with the floor 136 of the reservoir 140, the handle portions 320 of the cups 300 will not interfere with the closing of the lid component 200.

As mentioned above, the internal cavity 315 of each of the cups 300 has a first liquid holding capacity, which is a measure of the internal cavity's ability to hold a substance such as water. In other aspects, the internal cavity 315 may have a first volume. The reservoir 140 of the base component 110 of the cooking apparatus 100 has a second liquid holding capacity when the plurality of cups 300 are all positioned in the reservoir 140. Specifically, the reservoir 140 of the base component 110 may have a third liquid holding capacity when none of the cups 300 are positioned in the reservoir 140. However, when the cups 300 are positioned in the reservoir 140, the liquid holding capacity of the reservoir 140 is reduced by the space taken up by the cups 300. Thus, the second liquid holding capacity is an amount of the liquid (e.g., water) that can be placed into the reservoir 140 of the base component 110 while the plurality of cups 300 are all positioned in the reservoir 140 (see
In the exemplified embodiment, the second liquid holding capacity of the reservoir 140 of the base component 110 when all of the cups 300 are positioned therein is greater than the first liquid holding capacity of the internal cavity 315 of each of the cups 300 (or the second volume of the reservoir 140 with the cups 300 therein is greater than the first volume of the internal cavity 315 of the cups 300). More specifically, in the exemplified embodiment a ratio of the second liquid holding capacity of the reservoir 140 of the base component 110 when all of the cups 300 are positioned therein to the first liquid holding capacity of the internal cavity 315 of the cups 300 is at least 2:1, or at least 3:1. Thus, one of the cups 300 can be filled with water at least two (or three) times with the water then being introduced (or poured) into the reservoir 140 without overflowing the reservoir 140 even when all four of the cups 300 are positioned in the reservoir 140, as shown in

Moreover, although in the exemplified embodiment the cooking apparatus 100 includes the electric plug 190, in other embodiments the cooking apparatus 100 may receive power in other ways. For example, the cooking apparatus 100 may comprise an internal power source such as a plurality of batteries for powering the heating elements 132, 228. In such an embodiment, the cooking apparatus 100 may include a power button for powering the cooking apparatus 100 on and off. In the exemplified embodiment, there is no such power button. Rather, in the exemplified embodiment upon plugging the electric plug 190 into the wall outlet 400, power is automatically transmitted to the heating elements 132, 228 so that the heating elements 132, 228 can begin to generate heat.
Furthermore, once the electric plug 190 is plugged into the wall outlet 400, the light indicator 230 is activated. Specifically, the light source 231 of the light actuator 230 is activated to emit light through the light transmissive cover 232 of the light indicator 230 to indicate to the user that the heating elements 132, 228 are powered and heating up. In some embodiments, the light indicator 230 may be activated when the heating elements 132, 228 are heating up and, upon the heating elements 132, 228 reaching their maximum temperature, the light indicator 230 may be deactivated. However, even after the heating elements 132, 228 reach their maximum temperature, the heating elements 132, 228 will continue to emit heat until the electric plug 190 is detached from the wall outlet 400 despite the light indicator 230 being deactivated. Thus, the light indicator 230 may be activated to illuminate light when the heating elements 132, 228 are in a heating-up mode, and may deactivate upon the heating elements 132, 228 reaching maximum temperature even though the heating elements 132, 228 will continue to emit heat even after reaching maximum temperature so long as the electric plug 190 is plugged into the wall outlet 400. In an alternative embodiment, the light indicator 230 may be activated to illuminate light as long as the cooking apparatus 100 is powered via the electric plug 190 being coupled to the wall outlet 400.
As seen in
Moreover, as the heating plates 131, 221 are heated by the heating elements 132, 228, the heating plates 131, 221 heat the water 350 to boiling so that the water 350 is converted to steam 370. The steam 370 may then heat the food item 360 uniformly as the steam 370 fills in the cooking cavity 150. Generally, the food item 360 will be fully cooked when the water 350 in the reservoir 140 has completely evaporated.
