DETAILED DESCRIPTION OF THE INVENTION

[0032] The pasta machine of the present invention cooks pasta quickly, efficiently, safely and with little human assistance. In general, the pasta machine simply requires the user to place pasta within the machine, to turn the machine on, and then return back to the machine some period of time later (e.g., 20 minutes) to produce perfectly cooked pasta. In one embodiment, as herein described, the machine is designed specifically for cooking pasta, but it is possible for such a device to be used as a deep fryer, steamer or crock-pot. Moreover, while the first embodiment described below is concerned with cooking pasta, other types of foods can be cooked by the machine of the present invention, including potatoes, vegetables, beans, crab fish, etc.

[0033] Referring now to the drawings, FIG. 1 is a schematic illustration of the pasta machine 10 of the present invention, and FIG. 2 is an exploded view thereof. As shown in FIGS. 1 and 2, pasta machine 10 (also called pasta cooker) includes a housing 12, a water container 14, a colander 16, and a clear lid 18. Housing 12 includes a control panel 20, an LCD screen 22, and an electrical plug 24. Plug 24 provides electrical power to the pasta machine when plugged into an appropriate electrical receptacle. The operation of control panel 20 and LCD screen 22 is discussed further below.

[0034] Housing 12 further includes a body 30 in which various electrical and heating elements (not shown) are disposed. These electrical and heating components carry out the below-described heating of the present invention. The pasta machine's body 30 is shaped to provide a well 32 into which water container 14 is placed during operation. The body 30 of the pasta machine's housing includes an arm recess 34 and a handle recess 36 disposed at one end, as shown, and also includes a second arm recess and a second handle recess disposed at the other end of body 30 (not shown in FIGS. 1 and 2). Each set of arm and handle recesses 34, 36 are shaped to accommodate respective handles 50 that extend from the sides of colander 16.

[0035] Water container 14 is used to hold a preset amount (e.g., 5 quarts) of water and is shaped to fit into well 32 of housing 12, as mentioned above, and includes an edge 40 which supports water container 14 when placed into well 32. Water container 14 further includes a pair of openings 42, one on each end, to accommodate the arm portions 52 of each handle 50 extending from the ends of colander 16.

[0036] Colander 16 includes a container portion 54 and, as described below, is used to hold the pasta during cooking. Colander 16 also includes a cover 56 hinged to container portion 54 (or simply, container 54) via a set of hinges 58 (shown in FIG. 3), and a latch 60 designed to keep cover 56 in the closed position during operation (discussed below). Latch 60 is any appropriate device that may be manually unlocked to allow colander 16 to be opened. Like a typical colander, the colander's container portion 54 includes many apertures (i.e., holes) 62 to allow water to enter into and exit from the inner enclosure of colander 16. Similarly, the colander's cover 56 includes many apertures 64 to also allow water to enter into and exit from the colander's enclosure. As illustrated in FIG. 8, the container portion 54 of colander 16 includes a flat bottom surface 66 and, in the preferred embodiment, surface 66 does not include any apertures. Rather, colander 16 includes holes along its entire curved top surface 68, encompassing the entire cover 56 and the curved portions of the top surface of the colander's container portion 54, as best shown in FIGS. 4, 5, 7 and 8. As will be discussed, apertures 62 and 64 on colander 16 allow the boiling water to cook the pasta contained within the closed colander.

[0037] During operation, colander 16 is disposed above water container 14 and is supported on the two arm recesses 34 of housing 12. One of the handle arm portions 52 of colander 16 includes a fixed gear wheel 70 that comes into contact with an opposing drive wheel (not shown) disposed within arm recess 34 of housing 12. During operation, the drive wheel disposed within housing 12 is controlled to rotate gear wheel 70 thus rotating colander 16 about an axis extending through the colander's two arm portions 52.

[0038] Pasta machine 10 finally includes a clear lid 18 shaped to fully encompass colander 16 when resting on top of edge 40 of water container 14, and serves to prevent splashing of water during operation of the pasta machine. Lid 18 includes a wide opening 72 to enable steam to escape during operation. Although not shown, lid 18 optionally may include a heat resistant handle to allow removal of the lid without any risk of touching a potentially hot surface of lid 18 during use. Moreover, handles 50 of colander 16 similarly are heat resistant to allow lifting of colander 16 from the remaining components of the pasta machine after use, as further discussed below.

[0039] The operation of the pasta machine of the present invention will now be described with reference to FIGS. 3-12 of the drawings. To utilize the pasta machine, the user first removes water container 14, colander 16 and lid 18 from the pasta machine housing 12. Water container 14 is filled with a predetermined amount of water (e.g., 5 quarts) and, in the preferred embodiment, the top water level is identified within the water container to assist the user. Water container 14, now filled with water, is placed within well 32 of the pasta machine housing 12. Alternatively, water container 14 can be filled with water while disposed within housing 12. One (1) tablespoon of water preferably is added to the water.

[0040] As shown in FIG. 3, cover 56 of colander 16 is opened and a predetermined amount of pasta (e.g., 1 pound) is placed within colander 16. Cover 56 is closed and colander 16 is placed in the upright position within water container 14 (which is filled with water and disposed within housing 12), as shown in FIG. 4. As shown, in the upright position, the flat surface 66 (see FIG. 8) is disposed on the bottom immediately above the water. The user then places lid 18 on the assembled components to fully cover colander 16, as shown in FIG. 5.

[0041] Upon adding water to water container 14, filling colander 16 with pasta and assembling the components as discussed above, the pasta machine of the present invention now is ready to begin operating. Accordingly, the user turns on the pasta machine's power by depressing the power button on control panel 20, such as shown on the exemplary control panel 20 shown in FIG. 6. Next, the user selects the type of pasta (e.g., spaghetti, lasagna, linguini, etc.) using the appropriate buttons on control panel 20, and optionally may also select one of the cooking preferences available, such as regular or al dente in the case of cooking pasta. Alternatively, the user may set the time of operation of cooking. The operation of programming a cooking appliance and the associated electronics and firmware necessary to carry such operation are well known in the art and thus further description thereof is not provided except where necessary for an understanding of the present invention. Thus, the pasta machine of the present invention may include other types of control interface, including mechanical knobs or other devices, than those shown and described herein. An exemplary operation of the cooking machine of the present invention by a user is further described below with reference to FIG. 13 of the drawings.

[0042] Upon completion of programming the pasta machine of the present invention, the amount of time remaining until the pasta is fully cooked preferably is displayed on LCD display screen 22. After programming the pasta machine, the heating elements within housing 12 begin heating the water within water container 14. A thermostat (not shown) within housing 12 determines when the water within water container 14 is boiling, at which point, a motor within housing 12 begins rotating colander 16 via gear wheel 70 attached to the colander (see FIG. 2). Colander 16 is rotated slowly about the previously mentioned axis extending along arm portions 52 in the direction A shown in FIG. 7 so that the pasta within colander 16 begins to submerge into the boiling water. Colander 16 continues to rotate, as shown in FIG. 8, in the same direction (direction “B” in FIG. 8) until colander 16 is completely upside-down, where all of the pasta within the colander is submerged in the water.

[0043] Once fully submerged, the pasta machine causes colander 16 to rotate back and forth, first rotating in the same direction, “C” in FIG. 9, to the position shown in FIG. 9, then rotating in the opposite direction, “D” in FIG. 10, to the position shown in FIG. 10. This cycle then repeats itself. During this process, steam within the enclosed unit vents through opening 72 in lid 18. As shown in FIGS. 9 and 10, colander 16 “rocks” back and forth so that the pasta within the colander is rotated in and out of the water in repeated cycles until the required (predetermined) amount of cooking time has elapsed. Upon completion of cooking, colander 16 is controlled to rotate back in direction E shown in FIG. 11 back to its initial starting position, thus rotating the pasta completely out of the water, that is, the pasta is fully drained of water. At this time, LCD display screen 22 alerts the user that the pasta is fully cooked. Optionally, the pasta machine may provide an appropriate audible indication that cooking is complete. The user then removes lid 18 from the unit, lifts colander 16 via handles 50 to remove it from the pasta machine's housing and opens the colander's cover 56 to reveal fully cooked pasta, as shown in FIG. 12. Then, the now-cooked pasta is removed from colander 16 and served. The user turns off the pasta machine by depression of the power button on control panel 20.

[0044] If the user, however, does not remove colander 16 and likewise does not turn off the pasta machine, the pasta machine carries out a warming function in accordance with the present invention. Upon completion of cooking and rotating all of the pasta out of the water (see FIG. 11), as discussed above, the heating element within housing 12 is automatically set to a low setting to keep the water relatively hot. To keep the pasta within colander 16 warm, colander 16 is controlled to rotate the pasta into the water every several minutes (e.g., 5 minutes), and since the water is maintained at a relatively hot temperature, the pasta within the colander is maintained hot for an indefinite amount of time. Moreover, since the pasta is rotated through the hot water only one time every several minutes, the pasta does not cook further during this time. Moreover, based on user programming, and particularly identifying the type of pasta to be cooked, the warming process of the present invention optionally may be further enhanced by pre-setting (not by the user, but during design and construction of the pasta machine) how often the pasta is rotated through the water, and, if necessary, the amount of time the pasta is fully contained within the hot water, depending on the type of pasta. For example, due to characteristics of certain types of pasta, such pasta may be cycled through the hot water every 2 minutes, whereas other types of pasta may be cycled through the hot water only every 7 minutes, and so on.

[0045] Upon completion of cooking and removal of the cooked pasta, the pasta machine should be unplugged and the water within container 14 should be removed.

[0046] FIG. 13 shows an exemplary flow chart of programming and operation of the pasta machine of the present invention. Upon supplying power to the pasta machine, display 22 provides a suitable greeting in block 100, and then, in block 102, requests the user to indicate whether he/she want to program the pasta machine by identifying the type of pasta to be cooked, or to simply indicate the amount of cooking time. If the user indicates by pasta type, then the pasta machine requests the user to identify whether the pasta is long pasta or pasta shapes in block 104. In block 106, the particular type of pasta is selected by the user, in block the user identifies the amount of pasta to be cooked, and in block 110 the user identifies whether the pasta is to be cooked al dente or regular. Thereafter, operation of the pasta machine begins in block 112 and in block 114 the pasta machine identifies the amount of time remaining until the pasta is complete, and the current, particular cycle of operation—such as whether the water is being boiled or whether the pasta is being cooked (which, as previously discussed, occurs after the water has boiled). Upon completion of cooking, the pasta machine informs the user that the pasta is ready in block 116.

[0047] Returning to block 102, if the user desires to simply enter the amount of cooking time—in block 120—then the user enters that amount in block 122. Block 124 is the same as block 114, whereby the remaining amount of time is displayed along with the current cycle of operation of the pasta machine. The user is informed of completion of cooking in block 126.

[0048] In the above-described embodiments, the present invention has been described as a pasta machine for cooking pasta. Of course, the design may be modified if necessary to cook other types of foods. For example, the machine can be designed to be a deep fryer, a steamer or crock-pot and used to cook different types of foods including potatoes, vegetables, beans, crab fish, and so on. Accordingly, container 14 as described above is a water container. But, in various alternative embodiments of the present invention, the container may be used to contain other liquids such as oil in various different applications of the present invention. For example, as a deep fryer, the container is filled with oil which is heated by the heating element(s) within housing 12. Accordingly, the amounts of time particular foods within colander 16 are submerged within the heated oil may be pre-programmed, as well as amounts of time and time(s) between cycles of the warming process, all dependent upon the type of food being cooked/warmed.

[0049] Still further, the pasta machine of the present invention may be modified to be a steamer, where various dimensions of the components of the present invention are established so that food within the colander does not submerge within the boiling water, but is instead disposed immediately above the boiling water.

[0050] In another embodiment of the present invention, the colander is comprised of two or more compartments disposed side-by-side, where each compartment is separately controlled to rotate through the hot water. In such embodiment, different types of food/pasta may be cooked simultaneously by appropriately programming the pasta machine (i.e., identifying the respective types and amounts of pasta within the different compartments of the colander). In one example, the colander is divided into a left compartment and a right compartment, where two different types of pasta may be cooked within the different compartments. Of course, the two compartments of the colander may operate as a single compartment if the same type of pasta is being cooked in both compartments. In such case, both compartments are controlled to cycle through the hot water at the same time. If, however, different types of pasta are provided in the two compartments, then each compartment is separately controlled to cycle through the water. Also, warming is separately controlled for compartments containing different types of pasta.

[0051] In a further embodiment, both the colander and the container (e.g., water container 14) may each comprise multiple compartments, where different types of liquids may be provided in the different compartments of the container. For example, a left container compartment is filled with water, and a right container compartment is filled with oil, and thus the food within the left compartment of the colander is cooked in the boiling water and the food within the right compartment of the colander is deep fried. Of course, more than two compartments may be provided, and different types of cooking may be accommodated by a single device.

[0052] While the present invention has been particularly shown and described in conjunction with various embodiments thereof, it will be readily appreciated by those of ordinary skill in the art that various changes may be made without departing from the spirit and scope of the invention. For example, the specific shapes of the various elements may be modified to be different than that shown in the drawings. While preferred, the colander may include a non-curved top surface and/or a curved bottom surface, the water container may be rounded, and so on.

[0053] Therefore, it is intended that the appended claims be interpreted as including the embodiments described herein, the alternatives mentioned above, and all equivalents thereto.
