Patent Application
20080245357
The present is directed to grills, and more specifically outdoor grills for use in backyard cooking, for example.
Outdoor grilling is a popular way to cook foods, especially in warmer weather. Conventional grills utilize charcoal or wood, or may use liquid fuels, such as gas or propane. Most large outdoor grills that are used for backyard cooking include a firebox mounted about waist high on a frame. The frame typically includes wheels so that the grill may be rolled to a convenient location in the yard.
Conventional outdoor grills come in a variety of sizes and shapes, with various accessories. One problem with conventional grills is that a purchaser may have to make a decision between quality and accessories due to price constraints. As an example, a potential purchaser may want to buy a high quality grill, but cannot afford such a grill with all the accessories that the purchaser would like. The potential purchaser must make a decision between purchasing a high quality grill without accessories, or a lower quality grill that has the accessories that he or she desires.
In addition to the above, many grill users desire that their grills be capable of additional functions. The increase in outdoor cooking over the last few years has resulted in many users desiring that their grills serve many of the functions that are available in their kitchens. However, in reality, most outdoor grillers utilize the cook box of a grill for cooking a main course for a meal, and then run back and forth between a grill and an indoor kitchen for other cooking needs.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
In accordance with an embodiment, an outdoor grill is provided that has interchangeable, attachable modular accessories. As examples, the modular accessories may include a hot dog cooker, a steamer, a food preparation assembly, a side burner, a griddle, a deep fryer, a rotisserie, or other cooking accessories. Alternatively or additionally, the modular accessories may be accessories that are not used for cooking, including, but not limited to, an insulated container for beverages or food, or a light for illuminating the grill.
In accordance with an embodiment, at least some of the cooking accessories are sold separately from the grill, permitting a user to upgrade accessories when desired, or when the user's budget permits. By selling the cooking accessories separate from the grill, a potential purchaser may buy a high quality grill and then add accessories at a later point, permitting the total cost of the grill and accessories to be spread out over time, and allowing the purchaser to purchase the level of quality he or she desires.
In accordance with an embodiment, a grill in accordance with the invention permits a single grill frame and firebox to be sold in the same store with different cooking accessories. In this manner, the grill may be sold at various price points in the same store, and/or a purchaser may purchase a grill with exactly the desired accessory or accessories. Alternatively, the grill may be sold in one store with a particular cooking accessory or accessories, and in another store with a different accessory. Some combinations may be sold only at particular stores, allowing a manufacturer to market specific grill combinations to a particular chain or store, and thus permitting channel differentiation.
Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:
In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,
In the embodiment shown in the drawing, the stand 26 includes center doors 28, and rounded side doors 30, 32. A control panel 34 is mounted above the center doors 28. A right side table 36 is mounted above the right side door 32, and a left side table 38 is mounted above the left side door 30.
In accordance with an embodiment, the present invention provides modular, interchangeable accessories that may be attached to and used in connection with a grill, such as the grill 20. By a “cooking accessory,” or a “modular accessory,” we mean any item that may be removably attached to and used while an individual is cooking using the grill or in connection with the grill. The accessories do not necessarily have to be used in connection with the cooking. For example, as described below, one of the accessories may be an insulated container for holding beverages. As another example, a modular accessory might be a light for illuminating the grill.
The accessories may be attached anywhere on the grill, including directly to the firebox 22 or to the stand 26. To this end, as used herein, “stand” is meant to include any part of the grill that is not the firebox.
In the embodiment shown in the drawings, the interchangeable cooking accessories are removably attached to the left side table 38. However, in alternate embodiments, the interchangeable cooking accessories may be positioned on either of the side tables 36, 38, on a front of the grill 20, on a rear portion of the grill, underneath or over the firebox 22, may be mounted inside the firebox, or any combination of these. However, by placing the interchangeable cooking accessories on one of the side tables 36, 38, the accessories are readily available and are out of the way of a user that is cooking using the firebox 22.
In the embodiment shown in
Although not shown in the drawings, propane, gas, or other fuel that is utilized by the grill 20 is supplied to the burner for the hot dog cooker 40. The propane or other gas that is supplied to the hot dog cooker 40 may be supplied, for example, via a conduit that connects directly to the main manifold for the gas system for the grill 20. As is further described below, the hot dog cooker 40 is connected and disconnected to this fuel supply during installation and removal of the hot dog cooker 40, respectively. Example connections are described below.
The rotating cylinders 44 may be driven by batteries or AC power. In an embodiment, the rotating cylinders 44 are connected to a rotisserie motor (not shown) and are driven by that motor. The rotisserie motor may have a special connection that connects, for example, to a gear for the rotating cylinders 44 when the hotdog cooker is in place. If a separate motor is used for the hot dog cooker, power for the separate motor may also be supplied by a quick connect or other releasably connectable electrical connection.
During use, hotdogs are placed on the rotating cylinders 44, and the cylinders 44 rotate while heat is supplied to the cylinders via a fire in the burner. The continual rotation of the cylinders ensures that the hot dogs are cooked uniformly.
In the embodiment shown in the drawings, the modular accessories are mounted in an inset 46 in the left side table 38. The inset 46 includes a wide end 48 adjacent to the firebox 22 and a narrowed portion 50 on the distal side of the left side table 38. The narrowed portion 50 extends downward to include the bottom and outer extremities of the left side table 38.
In an embodiment, the modular accessories may be shaped so that they are slightly tapered and are held by gravity into the inset 46. Alternatively or additionally, fasteners, snaps, or other features may be used to position the modular accessories in place. In addition, if desired, different arrangements may be used for receiving the modular accessories. In an embodiment, a left side table 38 or other structure may not be provided, and the modular accessories may bolt or otherwise connect directly to the firebox 22 or the stand 26.
As can be seen, the food preparation assembly 60 does not include a propane burner and thus does not need a connection to propane or electricity. Thus, this modular accessory is a low end modular accessory, and may be provided, for example, with the grill 20 at a lower price than a grill provided with a more complex modular accessory (e.g., the hotdog cooker 40). As an alternative to the food preparation assembly 60, an insulated container may be provided that fits in the inset 46 and that serves as a beverage cooler. Other alternatives include, but are not limited to, a storage drawer, a refrigerator, a mini-keg cooler, or an extended table.
For each of the modular accessories that requires a burner, a quick connect gas coupling may be provided so that the modular accessory may be quickly connected to or disconnected from the gas manifold for the grill 20. An example is shown in
If the female connector 120 is used on the grill 20, each of the modular accessories that includes a burner or that otherwise utilizes fuel supplied by the grill 20 includes a male coupling, such as a male coupling 130 shown in
As stated above, such a connector is known in the art. Preferably, any coupling used with the grill will comply with American National Standards Institute, Inc. (ANSI) and the Canadian Standards Association's (CSA) standard for Outdoor Cooking Gas Appliances, ANSI Z21.58, CSA 1.6, and standard for outdoor cooking specialty gas appliances ANSI Z21.89, CSA 1.18. Alternative coupling mechanisms may also be utilized.
In an alternate embodiment, a fixed male coupling may be provided on the modular assemblies that automatically locks into a female connector, such as the female connector 120, positioned on the grill 20. As part of moving the modular assembly into place, the coupling is automatically locked into position. Then, to remove the modular accessory, the coupling is first disconnected, for example reaching under the modular accessory, or by an extended handle or another mechanism that may permit release of the coupling while grabbing the modular accessory to remove the modular accessory from the grill 20. Other configurations are also possible. For example, the grill 20 may include a female connector having o-rings into which a male nozzle of a modular accessory may slide when the modular accessory is put into place, the o-rings providing a seal between the female connector and the male nozzle. Insulation or other shielding may be used to keep users from burning themselves on the firebox or other parts of the grill 20 when connecting or disconnecting the coupling.
In accordance with an embodiment, the modular accessories discussed herein permit a manufacturer and/or a retailer to accessorize a grill as desired. For example, a grill may be sold with a low end modular accessory, such as the food preparation assembly 60, so as to lower the selling price of the grill and to permit a purchaser to buy a high quality grill without having to pay for accessories. This purchaser may at a later time buy one or more of the modular accessories so as to enhance the features available to the grill 20.
As another alternative, a manufacturer and/or retailer may package a grill, such as the grill 20, with more than one accessory. In addition, a manufacturer may differentiate a grill for one retailer over another by selling a specific modular accessory, such as the rotisserie assembly 100, with grills provided only to a particular retailer. This feature allows differentiation between a grill sold by one retailer and a grill offered by another.
In addition to accessorizing the modular accessories, the modular accessories that are offered with the grill 20 and/or the configuration of the stand 26 may be changed to meet certain price points and/or to differentiate the grill between one retailer and another. This modularity is provided without requiring different tooling for the firebox 22 and a frame for the stand 26. As an example, a low end grill 220 is shown in
For each of the grills 20, 220, there are a number of common features that do not require molding of separate parts. For example, the firebox 22, the right and left side tables 36, 38, and a frame for the stand 26 are all common. Thus, these parts may be used for multiple grills, reducing the expense of channel differentiation and parts storage.
In the embodiments described thus far, the various side accessories or cooking accessories are “drop-in” types of solutions. That is, as can be seen in
The accessories 202, 204, 206, 208 easily clip onto the vertical rails 214 via the brackets 210. In addition, if additional slots 212 are provided, such as in the embodiment shown in
In addition, if desired, one or more of the accessories 202, 204, 206, 208 may be usable at a lower storage position and while under another accessory. For example, one of the accessories, such as the accessory 208, may serve as food storage or as an insulated container for holding beverages. As such, the accessory 208 may be used at the lower level, for example to store food just prior to the food being put on the grill.
The grills described herein with the removable accessories provide quite a bit of flexibility for a user. With an adequate number of side accessories, a user may cook an entire meal at a grill, without having to run back and forth between the grill and a kitchen.
The modular accessories may be used with other free standing devices. As an example, a free standing sink may be provided that includes vertical rails such as the vertical rails 214.
