Abstract:
A food cooking apparatus with an integral basting pump system comprises a common countertop roasting oven, typically used to prepare turkeys and other large foodstuffs further performing the additional duty of automatically basting the foodstuffs. The apparatus collects basting liquid and juices from the foodstuffs at the bottom of the roasting pan area, where an electrically-powered recirculating pump transfers the liquid to the top of the oven for spraying or dripping down upon the foodstuffs being cooked. In such a manner the foodstuffs are kept moist and tender while reducing cooking time since the oven is not opened to perform a manual basting process. The basting application is controlled using a plurality of dials on the oven that govern application time, and application intervals.

Description:
RELATED APPLICATIONS 
     The present invention was first described in and claims the benefit of U.S. Provisional Application No. 61/288,546 filed Dec. 21, 2009, the entire disclosures of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates generally to cooking ovens, and in particular, to a standalone roaster oven with an automatic basting mechanism. 
     BACKGROUND OF THE INVENTION 
     Basting is a common cooking technique when preparing large pieces of meat such as a turkey, a chicken, roasts or the like. Such foods will become dry if they are not basted several times during the cooking process. Common basting liquids such as melted butter, liquid fat, meat drippings or liquid such as a stock are usually spooned over the food or applied with a conventional bulb-type siphon. 
     While such methods undoubtedly work, they do have some disadvantages. First, the chef may easily forget about the next basting interval causing an entire meal to be ruined. Secondly, the door of the oven must be opened to perform the basting process, thus causing uneven temperature regulation and increased cooking time. Finally, and perhaps most important, the basting process is not continuous in the sense that it is only performed during certain time intervals. This may allow the meat dry out between consecutive bastings which will permanently negatively affect its overall taste. 
     Various attempts have been made to provide food basting systems. Examples of these attempts can be seen by reference to several U.S. patents. U.S. Pat. No. 1,712,242, issued in the name of Zimmermann, describes a self-basting and turning roaster which enables a user to rotate a foodstuff within the roaster in order to evenly apply a basting fluid without having to remove the lid of the apparatus. 
     U.S. Pat. No. 4,061,083, issued in the name of Caliva, describes an automatic food roasting and basting device which provides a fire box with a rotating spit and a basting unit located above the spit. The Caliva device can be utilized with a belt or pulley and a separate motor to rotate the spit and basting unit in order to apply a basting liquid while rotating a spitted foodstuff. 
     U.S. Pat. No. 6,582,745, issued in the name of Northern, describes a self-basting cooking apparatus including an external pump and a container of a basting liquid which is automatically periodically pumped into the cooking apparatus. 
     U.S. Pat. No. 6,796,219, issued in the name of Rubin, describes an automatic basting apparatus for use with an oven including a pump apparatus disposed outside of the oven and a transparent reservoir for monitoring the fluid level without opening the oven. 
     While these devices fulfill their respective, particular objectives, each of these references suffer from one (1) or more of the aforementioned disadvantages. Many such devices require lengthy installation or setup. Also, many such devices require manual intervention on a periodic basis to enact the basting process. Furthermore, many such devices utilize an intermittent basting process which may allow the meat dry out between consecutive bastings. In addition, many such devices are not suited for indoor use. Moreover, many such devices must be installed in a permanent location and cannot be easily repositioned or transported. Accordingly, there exists a need for an automatic basting system without the disadvantages as described above. The development of the present invention substantially departs from the conventional solutions and in doing so fulfills this need. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing references, the inventor recognized the aforementioned inherent problems and observed that there is a need for a self-contained continuous basting apparatus which is quickly and portably utilizable in a variety of common locations. Thus, the object of the present invention is to solve the aforementioned disadvantages and provide for this need. 
     To achieve the above objectives, it is an object of the present invention to provide self-contained electrically heated cooking for foodstuffs and simultaneously provide automatic and accurately controlled basting of the foodstuffs. The apparatus enables control of cooking temperature, cook time duration, start delay, and a basting time interval. 
     Another object of the present invention is to provide a rectangular enclosure similar to a conventional countertop roasting oven further including a power cord, a removable lid, and a plurality of handles. 
     Yet still another object of the present invention is to collect a basting liquid from the enclosure and automatically reapply the basting liquid to contained foodstuffs. A bottom interior surface of the enclosure is slightly sloped to direct collected liquids to a liquid sump. The apparatus further includes a removable cooking rack to support the foodstuffs slightly above the bottom surface of the enclosure. 
     Yet still another object of the present invention is to automatically cycle basting liquid collected into the liquid sump with a plurality of tubes and an inline miniature electric basting pump which is housed within a side wall portion of the enclosure. A pickup suction arm located within the liquid sump is in fluid communication with the tubes and pump and allows collected liquid to enter the tubes. 
     Yet still another object of the present invention is to inhibit entrained solids within the basting liquid from blocking the pump, tubes, or nozzles by comprising a removable strainer located across a top opening of the liquid sump and a replaceable cylindrical filter which covers an open end of the pickup suction arm. 
     Yet still another object of the present invention is to enable fluid communication between the enclosure and the removable lid via a junction point comprising a removably attachable connection between a tubing joint disposed along a top rim portion of the enclosure and an upper riser tube fastened to a bottom surface of the lid. 
     Yet still another object of the present invention is to disperse basting liquid downwardly onto foodstuffs within the enclosure during use. Basting liquid within the upper riser tube travels into a dispersing header also fastened to a bottom surface of the lid. The dispersing header comprises a plurality of downward facing spray nozzles which spray the liquid under pressure from the pump to coat the contained foodstuffs. Excess liquid can then fall off onto the bottom surface of the enclosure in order to re-enter the liquid sump and continue the cycle. 
     Yet still another object of the present invention is to automatically turn off the pump and disable the dispensing function upon removal of the lid from the enclosure. A lip portion of the enclosure which supports the lid further includes an integral safety switch which disables the pump when it is not depressed. During a normal cooking cycle, the switch is depressed by the weight of the lid and the basting function is enabled. 
     Yet still another object of the present invention is to enable quick disassembly of the removable lid and dispersing header with use of removable fasteners, thereby facilitating quick and thorough cleaning of the apparatus after use. 
     Yet still another object of the present invention is to provide control of a plurality of basting process functions with an operating control panel disposed along an exterior portion of the enclosure. The control panel includes a plurality of dial knobs which allow a user to selectively control the ON/OFF state of the apparatus, a temperature setting, a delay start time, a basting interval, and the like. 
     Yet still another object of the present invention is to provide a method of utilizing the apparatus that provides a unique means of obtaining the apparatus, placing a foodstuff within the enclosure, adding a suitable volume of basting liquid within the enclosure, connecting the power cord to a suitable source of electric power, placing the lid on the lip of the enclosure, utilizing the operating control panel to activate and configure the apparatus, and benefitting from accurate and automatic basting of the contained foodstuffs. 
     Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The best mode for carrying out the invention is presented in terms of its preferred embodiment, herein depicted within  FIGS. 1 through 7 . However, the invention is not limited to the described embodiment and a person skilled in the art will appreciate that many other embodiments of the invention are possible without deviating from the basic concept of the invention, and that any such work around will also fall under scope of this invention. It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. 
     The present invention describes a self-basting roasting oven (herein described as the “apparatus”)  10 , which provides a conventional electrically heated and self-contained cooking means for foodstuffs  120 , particularly suited for poultry and other meat items, while providing an additional automatic and accurately controlled basting means. The apparatus  10  comprises a liquid sump  70  which collects basting liquids  115  from a bottom portion of the roasting apparatus  10 , and then pumps said basting liquid  115  to a superjacent dispersing header  105  to be sprayed down upon the foodstuffs  120  automatically during the cooking process. The apparatus  10  provides control of cooking temperature, cook time duration, start delay, and a basting interval time via a front mounted operating control panel  40 . 
     Referring now to  FIGS. 1 and 2 , front and side views of the apparatus  10 , according to the preferred embodiment of the present invention, are disclosed. The apparatus  10  comprises an elongated rectangular enclosure  15  having a large removable lid  30  being similar to conventional countertop roasting ovens. The apparatus  10  comprises a power cord  20  which is to be connected to a standard household 120 VAC power outlet  25 . The enclosure  15  comprises a pair of “U”-shaped first handles  35  permanently mounted to opposing short side portions of said enclosure  15  as would be expected. Additionally, the removable lid  30  further comprises a large “U”-shaped second handle  37  at a top center position allowing for easy access and removal of the foodstuffs  120  from within. An operating control panel  40  is located along a front surface of the enclosure  15  which comprises a plurality of rotary dials which govern operation and control of the apparatus  10  (see  FIG. 4 ). It is envisioned that the apparatus  10  be introduced in various sizes such as small, medium, and large, and in various attractive colors and patterns based upon a user&#39;s preference. Furthermore, the removable lid  30  is envisioned to be made using transparent, translucent, or opaque materials such as plastic, porcelainized metal, glass, or the like. 
     The enclosure  15  comprises an outwardly protruding lip portion  17  along an upper edge of the enclosure  15 . Said lip  17  further comprises a shelf-like feature along an inner upper edge which provides nested insertion of the removable lid  30  (see  FIG. 3 ). Said lip  17  also comprises an integral safety switch  27 , thereby providing a safe means to halt the basting process in an event the removable lid  30  is lifted from the enclosure  15 . Said safety switch  27  is preferably a conventional plunger-type pressure switch being in electrical communication with the operating control panel  40  via internal wiring  145  (see  FIG. 6 ). However, other types of switching devices may be utilized with equal benefit and as such should not be interpreted as a limiting factor of the apparatus  10 . During a normal cooking cycle, said safety switch  27  is depressed by the weight of the removable lid  30 , thereby enabling the basting function. 
     Referring next to  FIG. 3 , a sectional view of the apparatus  10  as seen along a line I-I, according to the preferred embodiment of the present invention, is disclosed. The internal operating components which distinguish the apparatus  10  from a conventional roasting oven are depicted here. A liquid sump  70  extends across an end portion of a slightly sloped bottom surface  80  within a cooking cavity portion  75  of the enclosure  15 . The liquid sump  70  provides a means to collect and recycle the basting liquid  115  and comprises a shallow recessed area approximately one (1) inch in depth and three (3) inches in width. The foodstuffs  120  are supported slightly above said bottom surface  80  of the enclosure by a removable cooking rack  77  which comprises an open welded wire construction to allow the basting liquid  115  and any juices from the foodstuffs  120  to drain freely into the sump  70  (see  FIG. 6 ). Said liquid sump  70  further comprises a removable strainer  86  which covers a top opening of said liquid sump  70 , being generally coplanar with the bottom surface  80  of the enclosure  15 . The strainer  86  comprises a plastic or stainless steel screen-mesh material which provides a means to separate out solid particles as the basting liquid  115  enters the liquid sump  70 . The liquid sump  70  further comprises a pickup suction arm  85  having a small press-on and replaceable cylindrical filter  88  being affixed to a proximal end portion of said pickup suction arm  85 . The filter  88  provides secondary removal of solids from said basting liquid  115  upon entering the liquid sump  70  and subsequently entering the pickup suction arm  85 . The strainer  86  and filter  88  act to prevent entrained solids from blocking the pump  65 , tubes  92 ,  90 ,  100 , dispersing header  105 , and nozzles  110 . A distal end portion of the pickup suction arm  85  is connected to a pump inlet tube  92  via a removably attached slip-fit tubing connection providing convenient disassembly. Said pump inlet tube  92  is in fluid communication with a suction side of an in-line miniature electric basting pump  65  which is envisioned to be integrated aesthetically into a side wall portion of the enclosure  15 . The basting pump  65  comprises a low pressure and low volume positive displacement or vibratory unit being capable of withstanding high heat exposure. The basting liquid  115  pumped from the basting pump  65  is routed upwardly through a lower riser tube  90  to the rim portion  17  of the enclosure  15  where it connects to a tubing joint  95  which provides a removably attachable fluid transfer means at the junction point between the enclosure  15  and the removable lid  30  (see  FIG. 5 ). In such a manner, the lower riser tube  90  remains physically attached to the enclosure  15 , while an upper riser tube  100  is removed when the removable lid  30  is removed. 
     The upper riser tube  100  is in turn removably inserted into an end portion of a dispersing header  105  which further comprises a plurality of downward facing threadingly attached spray nozzles  110 . When operational and the lid  30  is placed on the lip  17  portion of the enclosure  15 , the basting liquid  115  travels across the bottom surface  80 , into the liquid sump  70 , where it is picked up by the pickup suction arm  85 . The basting liquid  115  then travels through the pump inlet tube  92  to the basting pump  65  where it is pressurized and continues to travel upward through the lower riser tube  90  and upper riser tube  100  and into the dispersing header  105 . Once in the dispersing header  105 , said basting liquid  115  exits through the downward facing spray nozzles  110  under pressure, where it recoats the foodstuffs  120 . The excess basting liquid  115  falls off onto the bottom surface  80  of the enclosure  15  and repeats the process. This process provides a continuous basting of the foodstuffs  120  while being cooked, thus resulting in a meat product or the like which is moist and succulent to eat without continuous user intervention for manual basting during the cooking process. 
     The upper riser tube  100  is routed along an inner surface of the removable lid  30  being removably attached thereto via a plurality of molded-in or fastened tubing clips  102 . Said tubing clips  102  comprise “C”-shaped flexible protrusions which provide snapping retention of said upper riser tube  100 , thereby allowing easy disassembly for periodic cleaning. Said upper riser tube  100  is in turn connected to the dispersing header portion  105  via a slip-fit tubing connection. Said dispersing header  105  is affixed to the removable lid  30  along an inner top long axis of said lid  30  using a pair of threaded fasteners  140  such as screws, bolts, or the like. Said threaded fasteners  140  are envisioned to jointly fasten the second handle  37  as well as the dispersing header  105 , to the removable lid  30  as seen here, thereby allowing easy disassembly of said removable lid  30  and dispersing header  105  for cleaning. 
     The dispersing header  105  comprises an elongated cylindrical or ovular member which provides an internal fluid communication means to convey said basting liquid  115  to the spray nozzles  110 . Said basting liquid  115  is subsequently sprayingly deposited upon the subjacent foodstuffs  120  via said equally-spaced and downwardly-facing spray nozzles  110 . Said spray nozzles  110  are arranged in a linear fashion along a length of the dispersing header  105  and are envisioned to be capable of propelling said basting liquid  115  onto the foodstuffs  120  in various patterns such as, but not limited to: a conical spray, a fan-shaped spray, dripping, or the like. 
       FIG. 4  is a close-up view of an operating control panel  40  of the apparatus  10 , according to the preferred embodiment of the present invention, is disclosed. The dial portions of the operating control panel  40  provide control of basting process functions including a temperature setting dial  45 , an operating time dial  50 , a delay start time dial  55 , and a basting interval dial  60 . The basting interval control  60  provides activation of the basting pump  65  for approximately thirty (30) seconds, as a period of time selected upon the basting interval dial  60  has passed. The temperature setting dial  45  provides an “OFF” position to disconnect electrical power to the apparatus  10  in addition to providing a means to set a cooking temperature. 
     It is understood that the apparatus  10  is not limited to the particular aforementioned cooking controls and may be provided with additional control devices which may further enhance the basting and cooking process without deviating from the basic concept and as such should not be interpreted as a limiting factor of the apparatus  10 . 
     Referring now to  FIG. 5 , a partial break-away view of the enclosure  15  depicting a tubing joint portion  95  of the apparatus  10 , according to the preferred embodiment of the present invention, is disclosed. The basting liquid  115  is pumped upwardly through a lower riser tube  90  to tubing joint  95  being permanently affixed to an upper end portion of the lower riser tube  90 . The tubing joint  95  provides a removably attachable and sealed means to covey the basting liquid  115  into an upper riser tube portion  100  of the removable lid  30 . In such a manner, the lower riser tube  90  remains physically attached to the enclosure  15  while the upper riser tube  100  and removable lid  30  are removed. The tubing joint  95  comprises a cylindrically-shaped member made using a soft rubber compound and having a vertical center opening having a particular diameter to produce a sealed slip-fit connection with the upper riser tube  100  when inserted. Said upper riser tube  100  protrudes downwardly from the removable lid  30 , being correspondingly positioned so as to insertingly engage said tubing joint  95 . The upper riser tube  100  further comprises an integral sealing feature  103  comprising a rounded and protruding annular shape being formed in a wall portion of the upper riser tube  100  adjacent to a bottom end portion. When said bottom end portion of the upper riser tube  100  engages the tubing joint  95 , the sealing feature  103  provides an effective sealed slip-fit connection against said inner diameter portion of said tubing joint  95 , thereby preventing possible leaking of the basting liquid  115  when the basting pump  65  is running. 
     Referring to  FIG. 6 , an electrical schematic block diagram depicting the major electrical components as used with apparatus  10 , according to the preferred embodiment of the present invention, is disclosed. Electrical power is supplied to the apparatus  10  from a household 120 VAC power outlet  25  via a power cord  20  which is in turn routed through an electrical contactor  125 . Said electrical power is then conducted to an electrical heating element  130 , thereby providing a conventional means to cook the foodstuffs  120 . Power distribution to all electrical components of the apparatus  10  is performed via common wiring  145  within wall portions of the enclosure  15 . The control side of the electrical contactor  125  is activated by adjustment of the temperature setting dial  45  and an internal thermostat  135  present in the circuit. Starting time and operating time is governed through adjustment of the operating time dial  50  and the delay time start dial  55  in a manner similar to conventional controls. The basting pump  65  is powered for approximately thirty (30) seconds, as a period of time selected upon the basting interval dial  60  has passed. Such time intervals comprise a period of time as selected on the basting interval dial  60 . The process control devices provided upon the operating control panel  40  are the temperature setting dial  45 , the operating time dial  50 , the delay time start dial  55 , and the basting interval dial  60 . Said dials  45 ,  50 ,  55 ,  60  are envisioned to be of a simple analog variety; however, more complicated control equipment such as those provided by discrete electronic controllers, basic stamp modules, programmable controllers and the like can also be used with equal effectiveness, and as such, should not be interpreted as a limiting factor of the present invention. The safety switch  27  will disable power to the basting pump  65  and subsequent flow of the basting liquid  115  when the removable lid  30  is detached from the enclosure  15  by interrupting the flow of electrical current from the basting interval dial  60  to said basting pump  65  until the lid is replaced onto the enclosure  15 . 
     It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope. 
     The preferred embodiment of the present invention can be utilized by the common user in a simple and effortless manner with little or no training. After initial purchase or acquisition of the apparatus  10 , it would be utilized as indicated in  FIGS. 1 through 4 . 
     The method of utilizing the apparatus  10  may be achieved by performing the following steps: procuring a particular model of the apparatus  10  having a desired size cooking cavity  75  and exterior appearance; placing one (1) or more pieces of meat, poultry, or similar foodstuffs  120  to be cooked within the cooking cavity  75  of the enclosure  15 ; adding a suitable volume of initial basting liquid  115  into the cooking cavity  75 ; verifying that the temperature setting dial  45  is set to the “OFF” position; connecting the power cord  20  to a suitable source of electric power by plugging said power cord  20  into a 120 VAC power outlet  25  having sufficient current capabilities; placing the removable lid  30  upon the lip portion  17  of the enclosure  15 ; giving care to assure smooth engagement of the upper riser tube  100  into the tubing joint  95 ; utilizing the operating control panel  40  to set various operating parameters of the apparatus  10  by selecting a desired cook time using the operating time dial  50 ; selecting a desired delayed cooking start time using the delay time start dial  55 ; and, selecting a desired basting interval time using the basting interval dial  60 ; initiating the cooking cycle of the apparatus  10  by manually rotating the temperature setting dial  45  from the “OFF” position to a desired cooking temperature; and, benefiting from accurate and automatic basting of foodstuffs  120  afforded a user of the present invention  10 . 
     During utilization of the apparatus  10  to perform the cooking process, the foodstuffs  120  would be cooked or roasted in the conventional manner by the application of heat from the heating element  130 . During operation, the basting liquid  115  travels across the bottom surface  80  of the enclosure  15 , through the strainer  86 , and into the liquid sump  70  where it is picked up by the pickup suction arm  85 . The basting liquid  115  is filtered through the filter  88  prior to entry within the pump inlet tube  92 . The basting pump  65  pressurizes the basting liquid  115  and pumps said basting liquid  115  upwardly through the lower riser tube  90  and upper riser tube  100  and into the dispersing header  105 . Once in the dispersing header  105 , said basting liquid  115  exits through the downward facing spray nozzles  110  under pressure, where it recoats the foodstuffs  120 . The excess basting liquid  115  then reenters the liquid sump  70  to repeat the basting process. The apparatus  10  provides a continuous basting of the foodstuffs  120  while being cooked, thus resulting in a meat, poultry, or similar foodstuff product  120  that is moist and succulent to eat without continuous user intervention for manual basting during the cooking process. At anytime during the basting process, if the removable lid  30  is lifted upwardly, the safety switch  27  will discontinue the action of the basting pump  65 , thereby prohibiting the flow of basting liquid  115  through the downward facing spray nozzles  110 . After the cooking process is completed, the foodstuffs  120  are removed for consumption and the remaining basting liquid  115  poured out. 
     Various components of the apparatus  10  may be disassembled and/or cleaned to allow for future usage, including the pickup suction arm  85 , the strainer  86 , the filter  88 , the upper riser tube  100 , the dispersing header  105 , and the downward facing spray nozzles  110 . Additional cleaning of the apparatus  10  is envisioned to be accomplished by assembling the apparatus  10  and circulating a heated solution of water and cleansers through the major components of the apparatus  10  by cycling the basting pump  65  as described above, being followed by a clean water rinse prior to storing the apparatus  10  until once again needed at a later date.
