Embodiments of the present disclosure relate generally to cooking stations having a griddle intended for outdoor use. More specifically, aspects of the present disclosure relate to grease and food byproduct management methods and systems utilized in conjunction with the griddle and/or cooking station. Further aspects of the present disclosure include providing a griddle station base with various features, such as cabinets, wheels, folding legs, a modular configuration and the like.
Outdoor cooking is a popular tradition in much of the world. Outdoor cooking may be achieved via various modes, but the most common systems utilized for cooking outdoors are barbeque grills, devices which cook food by providing heat in an area below a grill or grate. The heat is often provided via two methods: (1) a gas fuel, such as propane, or (2) a solid fuel such as wood and/or charcoal. Other modes include electrical heating elements. These two types of barbeque grills are generally referred to as “gas grills” or “charcoal grills.”
A griddle is a cooking device that is used in both residential and commercial applications for a range of cooking methods. While griddles gained prominence in the United States in the 20th century as used in commercial establishments such as diners and fast-food restaurants, the use of outdoor griddles was limited. A griddle is commonly a metal plate made of cast or wrought iron, aluminum, or steel. Griddles may be heated by open flame or electrical elements, directly or indirectly. Since a griddle is usually made of a heavy metal, griddles are notoriously difficult to move or otherwise transport. One method utilized in outdoor cooking was to place a small griddle directly on a barbeque grill or over flame burners. However, this method may lead to injury or accident, as there are limited options for controlling or handling a griddle within a barbeque grill.
Cooking on a griddle also produces grease and food byproduct that can accumulate on the solid surface. Some griddles include a drain system to manage the grease, such as a front channel used in commercial griddles at diners or restaurants. A front channel is unsightly and reduces the amount of useable, accessible griddle space for the cook. Front channels also potentially increase the likelihood of grease spillage and build-up over the front side of the cooking station, which may soil a user's clothing. Attaching a collection reservoir to the rear of the griddle can also expose users or passers-by to grease, either by proximity or accidental contact with the reservoir. Furthermore, most or all griddles utilized in residential and commercial settings are open-air cooking surfaces that do not include a lid that covers the entire cooking surface during use. This increases the likelihood that a user's clothes will be soiled by splashing or unanticipated movement of grease or food byproduct during use.
It is an object, feature, and/or advantage of the present disclosure to provide an improved outdoor griddle station and methods of use thereof that overcome deficiencies in the prior art. In accordance with one exemplary aspect, a cooking system is provided having a heat source containment structure housing with at least one heating element disposed therein. A griddle member is adapted for placement in overlying relation to the heat source containment structure. The griddle member includes an upper side and underside. The upper side defines a cooking surface wherein heat is transferred from the heating element to the food product via the griddle. This cooking surface here provides a heat transfer zone. At least one drain may extend through the griddle member. The drain may include a proximal opening at the upper side and a distal opening below the upper side, and further includes downwardly extending side walls extending in a convex manner from the proximal opening to the distal opening. A fluid transfer assembly may extend downwardly away from the drain or drains in nested relation and fluid communication with the drain or drains. The fluid transfer assembly has a basin element and a downwardly extending hollow duct. The basin element may be oriented in least partial surrounding relation to said downwardly extending sidewalls. A receptacle is disposed below the duct and is adapted to receive and hold food byproducts transported through the fluid transfer assembly. The receptacle may have a box configuration including an open top, a floor, a pair of opposing end walls, and a pair of opposing side walls with the end walls and side walls being disposed around the floor.
The accompanying drawings, which are incorporated in, and which constitute a part of this specification, illustrate exemplary constructions and procedures in accordance with the present disclosure and, together with the general description of the disclosure given above and the detailed description set forth below, serve to explain the principles of the disclosure wherein:
While constructions consistent with the present disclosure have been illustrated and generally described above and will hereinafter be described in connection with certain potentially preferred embodiments and practices, it is to be understood that in no event is the disclosure limited to such illustrated and described embodiments and practices. On the contrary, it is intended that the present disclosure shall extend to all alternatives and modifications as may embrace the general principles of this disclosure within the full and true spirit and scope thereof. Also, it is to be understood that the phraseology and terminology used herein are for purposes of description only and should not be regarded as limiting. The use herein of terms such as “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
An outdoor griddle station provides advantages over an indoor griddle station in homes where kitchen space is limited. Many foods cooked on griddles produce excess smoke, which many kitchens are ill-equipped to disperse. Providing a grease management system near the back of the station allows the user to use the front of the station closest to them as a cooking surface, reducing the need to reach over a hot griddle to reach cooking food in the back.
An outdoor griddle station including a separate base and griddle member allows for easier cleaning of the griddle member. The griddle member can also be removed from the base to allow for more compact storage. In one embodiment, the base may be composed of a housing for the heating element arranged in a box shape. This heat source containment structure, or firebox, contains one or more heating elements that apply cooking heat to the heat transfer zone of the griddle member, which functions as the cooking surface.
A griddle member with securing members and griddle walls provides a stable cooking surface and prevents grease from spilling off of the cooking surface. The securing members also maintain the griddle member at an elevated distance above the firebox. Additionally, a griddle member with heat deflecting members on its underside prevents the heat from the heating element from escaping out the sides of the griddle member, which directs more heat towards the griddle surface resulting in more efficient heat transfer. This also prevents escaping heat from overheating the user's tools or anything else adjacent to the outdoor griddle station. Further, a griddle member with reinforcing members on its underside prevents the griddle surface from warping due to consistent exposure to high temperatures from the heating element.
The cooking surface of the griddle member may contain one or more drains having a generally inverse frustoconical geometry. That is, the drain or drains may have an opening of greater area at the top than at the bottom with sloping walls extending between the top and bottom openings. One or more generally elliptical drain openings on the griddle member may be used to collect grease from most spatulas and grease pushers. In this regard, it is to be understood that the terms “elliptical” or “ellipse” means any non-circular geometry with a length to width ratio greater than 1 with rounded or pointed ends and curved or straight lateral sides. The ends and lateral sides may be formed by curved surfaces, collections of straight-line segments, or combinations thereof. The curvature of the ends and any curved lateral sides may be either continuous or discontinuous. By way of example only and not limitation, elliptical openings may include a regular oval shape, a polygon having a pair of parallel line segments connected by a convex curve at each pair of ends, a polygon having two pairs of parallel lines arranged in rectangular fashion with convex curves in place of corners, forming a rounded rectangle, and stretched polygonal shapes such as hexagons, octagons and the like using line segments to provide a length to width ratio greater than 1.
When pushed, grease collects along the edge of a spatula or pusher, causing it to spread out. A rounded opening provides a wider hole to catch more grease while sacrificing less cooking area than a circle or square opening with the same width. The opening of the drain and the sloping portion of the cooking surface adjacent to the drain may be substantially elliptical in shape to prevent grease from building up in any corners. In addition, providing a sloped surface adjacent to the grease opening makes grease collection easier by allowing the grease at the edge of the sloped surface to flow downwards into the rounded opening. Instead of pushing all of the grease through the opening, the user only needs to push the grease to the beginning of the sloped surface for it to be directed to a grease receptacle.
The griddle member may include a raised perimeter wall defining a guard extending upwardly from the cooking surface. This guard is intended to protect users and nearby persons from grease splatter caused by boiling grease. In another nonlimiting exemplary embodiment of the griddle member, the entire cooking surface may be configured to slope toward the opening. When the grease is heated by the cooking surface, its viscosity, and therefore its resistance to flow, is lowered, allowing the hot grease to flow across a surface featuring less slope. In this way, the grease may naturally flow downwards toward and into the drain from any part of the cooking surface.
Providing a grease receptacle located within the base of the outdoor griddle station protects the grease tray from being accidentally knocked off of the station by the user or other passerby, reducing the chance of a mess and/or grease burns. The receptacle may be located below the heat source containment structure for ease of access. The receptacle may also include laterally-extending support flanges extending from the top of the receptacle. The flanges may rest upon a bracket seat attached to the griddle base to permit the receptacle to be removed and replaced. The receptacle may also include a handle attached to an end wall, which may made of a low thermoconductivity material to prevent the handle from becoming hot to the touch. The receptacle may optionally be made of metal such as aluminum, steel or the like capable of holding hot fluids without warping due to heat.
A fluid transfer channel, shaped similar to a funnel, may be attached via a mounting flange attached to the heat source containment structure below the griddle. The fluid transfer channel maximizes the amount of grease collected from the rounded opening and directs the grease to the receptacle. The top of the fluid transfer channel is shaped like a basin, with a wider top opening and narrower bottom opening. The narrower bottom opening is operatively connected to a hollow duct. A wider opening of the proximal end of the basin maximizes the amount of grease collected from the rounded opening, while the duct attached to the narrower distal end of the basin element directs the food byproduct directly to the grease receptacle. Both the basin and the hollow duct have heat shielding properties that allow the grease to flow through the channel, which passes through the heat source containment structure where the cooking heat source is located, without catching fire. The basin element of the fluid transfer assembly may be comprised of a metal such as aluminum or ferrous metal that provides modest heat shielding capacity to prevent grease fires. Because the hollow duct passes closer to the heating element, it may need to offer greater heat shielding than the basin element. In order to supply heat shielding, the hollow tube may be composed of a metal or other material with a thickness sufficient to offer heat shielding sufficient to eliminate the potential for a grease fire. The hollow duct may be cylindrical or elliptical in shape in order to minimize the effect of thermal expansion based on the duct's proximity to a heat source. The basin element may have vertical walls at its upper perimeter extending from the wider top opening to allow one or more drains in the griddle member, which protrude downward from the underside of the griddle member, to nest in the basin member without touching the downward-sloping walls of the basin. Such nesting aids in communicating food byproduct from the surface of the griddle to the fluid transfer assembly without spillage.
In accordance with one exemplary practice, including foldable legs on the outdoor griddle station base allows users to transport the griddle via car. With foldable legs, the griddle can fit in the trunk or back seat of most family cars, whereas non-foldable legs would prevent this. The foldable legs also allow it to take up less space in storage. Optionally including wheels on the base station increases the mobility of the outdoor griddle station. This allows the user to move it to and from a storage area, or to move the griddle to allow for more outdoor space, for example to entertain a dinner party. Optionally including cabinets and shelves on the base station increases the user's utility of the outdoor griddle station, allowing them to store things such as spatulas, tongs, and towels, keeping everything they need in order to utilize the outdoor griddle station within the outdoor griddle station. Optionally including space for a fuel source increases the user's utility of the outdoor griddle station, allowing the station to occupy less space and allowing a more aesthetically-appealing location to store a fuel tank.
Optionally including space for a fuel source within the outdoor griddle station allows the griddle station to operate absent a direct gas line. This increases the mobility of the station, allowing the user to use it essentially anywhere they can move it provided they have a propane tank. Keeping the fuel source within the station reduces the amount of space the station and fuel source take up, and also reduces the risk of the user or somebody else bumping into the fuel source or line and disconnecting it. Optionally including a connecting mechanism for a fuel source in the outdoor griddle station allows the griddle to be connected to a gas line, eliminating the need of the user to constantly switch propane tanks.
Optionally including a lid on the outdoor griddle station allows the user to store the griddle outside without debris coming into contact with the griddle surface. Additionally, closing the lid while cooking food on the griddle surface increases the internal temperature and cooks the food from both the bottom and the top, resulting in lower cook times. The incorporation of a thermometer, heating/warming rack, and/or utensil holders with the optional lid provide further advantages.
