DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] What follows is a detailed description of the preferred embodiments of the invention in which the invention may be practiced. Reference will be made to the attached drawings, and the information included in the drawings is part of this detailed description. The specific preferred embodiments of the invention, which will be described herein, are presented for exemplification purposes, and not for limitation purposes. It should be understood that structural and/or logical modifications could be made by someone of ordinary skills in the art without departing from the scope of the invention. Therefore, the scope of the invention is defined by the accompanying claims and their equivalents.

[0028] FIGS. 1a-b illustrate a front and a back perspective view, respectively, of a cooker according to an embodiment. As shown, the cooker 100 includes a main housing 110 and a main lid 105 associated with each other through a hinge 107 (FIG lb) located in the back of cooker 100. The hinge 107 may be any standard hinge such as a barrel or a pivot hinge. When the mail lid 105 is closed as shown in FIGS. 1a-b, automatic locking, or the option to lock, is preferably offered to the user so that the main lid 105 is secured (such as for safety reasons) to the main housing 110 using typically a standard locking mechanism (not shown), such as an electromagnetic lock. In combination with such a locking mechanism, a release/unlock button (such as a push button) 106 may be provided to allow for the manual or the automatic opening of main lid 107 (such as when main lid 107 is spring loaded when closed).

[0029] The main housing 110 may be made from known suitable materials such as ABS plastic or aluminum. The inner containers (see for example 316 in FIGS. 3a-b) may be made from materials such as stainless steel, aluminum, copper, ceramic and so on.

[0030] The main lid 105 may have a transparent portion 103 made from materials such as plexiglass and sealed using, for example, a rubber gasket 104, to the remaining portion of main lead 105. The transparent portion 103 may improve the appearance of the cooker and it may allow for visual monitoring of the cooking, which in turn may give the user the feeling that she has better control over the cooking. Furthermore, for marketing purpose, the trademark under which the product is marketed may be placed in the product name area 102, in the center of the transparent portion 103 of main lid 105, by, for example, engraving it, affixing a tag, and so on.

[0031] It should be noted that, as depicted in FIGS. 1a-b, the cooker 100 has an indented handle 101 on each side, for easy and convenient grip during lifting and/or manipulation of cooker 100 such as for storage purposes. Furthermore, preferably in the front of main housing 110, a control and/or display panel 108, preferably a digital one, is available to the user. Through the panel 108 the user may set and/or monitor rice cooking parameters such as time and temperature.

[0032] FIG. 3a illustrates a front-perspective view of a cooker 300 with the main lid 305 open and having a three-container configuration, according to another embodiment. FIG. 3b illustrates a sectional view of the cooker from FIG. 3a. As stated earlier, the multi-sectional cooker gives options to the user. For example, using a three inner container 316 configuration, the user may simultaneously cook three kinds of rice, for example, a Middle-Eastern rice (e.g., crunchy on the surface) in one container, an Eastern/Oriental rice (e.g., non-crunchy but spicy) in another container, and finally, an Italian rice (e.g., risotto). This, again, it is very convenient when, for example, a family has members, or a party has invitees, from these three different culinary cultures and regional cuisines.

[0033] It would be understood by one of ordinary skills in the art that, without departing from the scope of the invention, the cooker 300 may be configured to have more than three inner bowls/containers 316 (e.g., four or five) and that they may be substantially equal in size as shown in FIG. 3a, or they may have various sizes. For example, in a three-container configuration, one of the inner containers 316 could be smaller than the other two when a group of family members from a given culinary culture is smaller than the other two groups. To accommodate for such situations, the cooker 300 may be provided with, for example, a set of three equal inner containers 316 and a set of two relatively larger and one smaller container each set being configured to fit inside the cooker 300.

[0034] For exemplification purposes, the configuration with three equal inner containers 316 is depicted in FIGS. 3a-b, and thus, will be emphasized herein. It should be noted that, when the main lid 305 is open, the upper edge 316a, and thus, the inner lids 316b, of inner containers 316 are relatively higher than the upper surface 310a of main housing 310. This feature is advantageous when user needs to grasp on the inner containers 316 for the purpose of, for example, removing them from the cooker 300, and it is made possible by the springs (or other similarly compressible elements) 317 shown in FIG. 3b. As shown, each inner container is preferably actuated by a separate spring (or plurality of springs, not shown). The springs 317 are compressed under the influence of the weight of the main lid 305 on the inner containers 316, and thus, on springs 317, and/or a pressure/push action on the main lid 305 by the user, combined with the locking of the main lid as explained earlier, so that the springs 317 remain compressed while the main lid 305 is closed. Upon opening of the main lid 305, the springs 317 are decompressed and cause the lifting of the inner containers 316.

[0035] It should be noted that the inner containers may be heated, so that the cooking of the rice is possible, by any standard means known in the art, such as by using heating elements (not shown), including induction heating elements, resistors, etc, and the supporting circuitry (not shown) including but not limited to microprocessor for controlling cooking cycles, and other components (switches, sensors, etc) for, for example, turning the power on and off, controlling the power level, the cooking temperature, the cooking time, and so on. As described earlier, from the control panel 308 the user may preferably be provided the option to set and/or monitor rice cooking parameters such as time, temperature and/or power level, and so on, or a combination thereof. The setting of the cooking parameters is preferably individual for each inner container 316, such that different settings may be selected for each container, and thus, different types of rice may be cooked in each container. Furthermore, the heating element's supporting circuitry may be programmed such that the user may have the option to select from a list of rice types, by, for example, providing a push button for each type of rice on the control panel 308, which when activated, automatically sets the cooking parameters for the respective type of rice, desired to be cooked in a given inner container 316. It should be understood that in the inner containers 316, dishes other than rice, such as soup, stew, porridge, and so on, may potentially be cooked the same way as explained above.

[0036] The cooker 300 is also preferably configured to provide automatic recognition, and displaying on the display portion of panel 308, of how many inner containers 316 are operational at a certain time. This means one less concern or task to be performed by the user, who in most parts may be a non-technical person. The automatic recognition may be achieved by, for example, detecting, such as by using weight/load sensors, the weight load pressing on springs/compressible elements 317. As shown in FIG. 3b, the cooker may have three springs/compressible elements 317, one for each of three inner containers 316. Thus, for example, when only the two distal elements (317) are actuated, such as when the three inner containers 316 are replaced with only two larger inner containers 440 (see FIGS. 4a-b), the middle element is free, therefore, its sensor, switches, etc, will not detect any weight load, and thus, the display of panel 408 will show that only two inner containers are in operation.

[0037] In another example, when, of the three inner containers 316, only the one on the left is operational, the display portion of panel 308 may show, for example, 1L. Similarly, when the containers in the center and on the right are in use, 1C and 1R may be shown to user.

[0038] Yet another example, when the three inner containers 316 from FIG. 3a are replaced with a single large bowl 550 as shown in FIGS. 5a-b, then the weight of the one container 550 will be distributed to the three springs/compressible elements 517. Thus, each spring/compressible element 517 will have a different weight load when compared to the weight load coming from three individual containers 316. Hence, this will be the determining factor for the controls to know whether one container or three containers are used.

[0039] Alternatively, other approaches may be adopted for achieving the automatic recognition described above. For example, instead of a weight load approach, a combination of contact sensors could be used.

[0040] It should be noted that the main housing 310 may be double-walled such that a gap 310b is created in between. The gap may be filled with, for example, air, and may contribute to the increase in the thermal insulation of the inside of the main housing 310, and thus, to the improvement of the cooking process.

[0041] FIGS. 3c-d illustrate the nesting during storage or shipping of the three inner containers 316 and their lids inside the cooker from FIG. 3a, according to another embodiment. As shown, the three inner containers 316 may be configured such that they may be placed inside each other, and at one end of the inside of the main cooker housing 310, while their lids 316b may be stacked at the other end of main housing 310. This configuration may facilitate storage and/or shipping.

[0042] FIG. 4a illustrates a front-perspective view of a cooker with the lid open and having a two-container configuration, according to another embodiment. FIG. 4b illustrates a sectional view of the cooker from FIG. 4a. Except for the differences noted therein, the description above referring to the cooker having three inner bowls and depicted in FIGS. 3a-b applies to the two-container cooker depicted in FIGS. 4a-b, and is therefore incorporated herein by reference.

[0043] It should be noted in FIGS. 4a-b that the lids 440b of the inner containers 440 may have a handle 440c for easy grip and manipulation by user.

[0044] FIGS. 4c-d illustrate the nesting during storage or shipping of the two inner containers 440 inside the cooker from FIG. 4a, according to another embodiment. As shown, when the main lid 405 is opened fully (449), similarly as described above when referring to the three-container cooker, the two inner containers 440 may be nested (441) inside the cooker on one side and their lids (not shown) on the other side. Again, this configuration may facilitate storage and/or shipping.

[0045] It should be noted that the cooker and its inner containers may be sized such that, for example, the two bowls/inner containers 440 (FIGS. 4a-b) can be nested inside the one half of the large bowl 550 (FIGS. 5a-b) while the three bowls 316 (FIGS. 3a-b) may be nested inside the two bowls, and all lids for the two (440b) and three (316b) sets may be nested inside the other half of the large bowl 550, and the lid 550b of the large bowl 550 on top of everything; in other words, a configuration that allows all bowls and their lids to be nested inside the cooker for convenient and space saving storage in the user's kitchen and for savings on shipping costs.

[0046] FIG. 5a illustrates a front-perspective view of a cooker with the lid open and having a one-container configuration, according to another embodiment. FIG. 5b illustrates a sectional view of the cooker from FIG. 5a. As described earlier, the user may replace the three inner containers 316 (see FIGS. 3a-b) or the two inner containers 440 (see FIGS. 4a-b) with one large container 550 (see FIGS. 5a-b) such as when, for example, everybody agrees on the style, recipe and/or taste of the rice to be prepared. Thus, the cooker disclosed herein provides superior versatility as it can be used to simultaneously prepare two, three or more styles of rice, or, if needed, only one style of rice for everybody.
