[0124] With reference to the accompanying drawings Figures 1 to 9d , schematically depicts a first embodiment of a cooking device 10 in the form of a barbecue grill 12. The barbecue grill 12 includes a body 14 having an interior cavity 16 in which a heat source 15 may be located. In the illustrated embodiment, the heat source 15 is in the form of a burner assembly 17. However, it will be appreciated that other suitable forms of heat sources may be provided, as will be discussed in greater detail below. In the depicted embodiment, one or more removable cooking surfaces 20, such as hot plates or grill racks, may be located above the heat source 15. The barbecue grill 12 may optionally be provided with a flame tamer 23 (see Figure 5 ), which is located below the one or more removable cooking surfaces 20 and above the heat source 15. The flame tamer 23 may include at least one metal tab 23a to engage a corresponding magnet (e.g., magnet 58, described below) to facilitate installation within the interior cavity 16. A removable cover 22 may be mounted to the body 14 to at least partially cover or extend over the interior cavity 16. The body 14 of the grill 12 may be formed from one or more sections to enclose and support the interior cavity 16 and may be adapted to support the control knobs 19 and the removable cover 22.

[0125] The inner cavity 16 includes one or more sidewalls 26 and a bottom 28. Preferably, the bottom 28 includes an orifice 30 that provides a drain 32. The inner cavity 16 can be formed as a substantially integral part, such that the sidewalls 26 and bottom 28 provide a substantially smooth, integral surface 34 configured to direct fluid to the drain 32. In a preferred form, the substantially smooth, integral surface 34 is configured to direct a large volume of fluid to the drain 32. It should be understood that the junction or corner 31 between the sidewalls 26 and bottom 28 can be rounded or curved. The inner cavity 16 can be formed from a single piece of material, such as, but not limited to, a metal that can be press-fitted, such as stainless steel. In other examples, the metal can be a magnesium alloy or aluminum. In a preferred form, the metal is a non-ferritic metal. In other forms, the inner cavity 16 can also be formed from a single piece of non-metallic material (e.g., carbon fiber), which is preferably heat-resistant and durable. The shape of the inner cavity 16 can be, but is not limited to, square, circular, or rectangular. The inner cavity 16 can be adapted, shaped, or inherently suited to reflect heat.

[0126] The inner cavity 16 may have a rim 36 (see Figure 1 and Figure 9a ), the removable cooking surface 20 may be located on top of this rim. Rim 36 may be rounded or curved. The interior cavity 16 may also include one or more vents 38, preferably located in or on the sidewall 26, facing and below the cooking surface 20. In one form, the interior cavity 16 may include a gas port aperture 40 through which one or more gas inlets or ports 42 extend. Airflow to the gas ports 42 is preferably controlled by a control knob 19. It should be understood that other controls or actuators may be provided to control the flow of gas to the gas ports 42, such as, but not limited to, one or more levers, buttons, switches, etc. Rim 36 may also be formed integrally with the interior cavity 16. Rim 36 may support magnets 72 for connection to the cooking surface 20 and / or the lid 22. The body 14 may include a side surface or tray 61 shaped to direct fluid toward the interior cavity 16. In one form, the side surface or tray 61 extends toward the interior cavity 16 and is sloped or angled to direct fluid on the tray toward the interior cavity 16. The junction between the side surface or tray 61 and the inner cavity 16 can be curved or rounded. In some examples, the side surface or tray 61 can also be formed as a single piece with the inner cavity 16.

[0127] In the depicted embodiment, the burner assembly 17 includes at least one burner 44 having a tubular shape adapted to be releasably connected to an associated one of the gas ports 42. In the illustrated embodiment, the burner 44 includes at least one bracket 46 arranged to position the burner 44 so that, in an assembled or mounted state, the burner 44 spans transversely across the interior cavity 16 above the bottom 28. As described above, while in the illustrated embodiment, the heat source 15 is a burner assembly 17 adapted to burn gas, other forms of heat sources may be used. For example, the heat source 15 may be a single charcoal box, container, basket, or tray, or a combination of a charcoal box, container, basket, or tray and the burner assembly 17. These alternative arrangements will be described in more detail below. In examples where the heat source is a charcoal box, container, basket, or tray, the charcoal box, container, basket, or tray is adapted to support the charcoal to be burned, and in some examples, the charcoal box, container, basket, or tray can be arranged so that the charcoal supported in the charcoal box, container, basket, or tray can be ignited by gas supplied from gas port 42. It should be understood that heat source 15 can be interchangeable between different types of heat sources, such as burner assemblies 17, charcoal boxes, containers, baskets, trays, etc. It should be understood that heat source 15, such as a burner assembly or charcoal box, container, basket, or tray, may not necessarily be coupled to the inner cavity via a magnetic coupling mechanism, as described in more detail below. For example, heat source 15 can be adapted to be positioned within the inner cavity via other suitable engagement mechanisms, such as shallow positioning grooves, notches, or holes in or on the sidewalls 26 or bottom 28 of inner cavity 16. Alternatively, heat source 15 can be adapted to simply sit within the inner cavity without requiring a secure positioning mechanism. For example, the heat source 15 may be adapted to be press-fit into the internal cavity 16 so as to be positionable therein during use.

[0128] In the described embodiments, and as Figure 4 As best shown in FIG. 1 , two burner assemblies 17 are provided, and each burner assembly 17 may include two parallel burners 44 (in the form of tubes) connected by struts (connector members) 48 (see FIG. 1 ). Figure 5 ), and two brackets 46 extend from each burner 44 to be located above the base 28. Each bracket 46 can be adapted to be retained by a coupling device 50 to position and retain the bracket 46 to the base 28. The brackets 48 can provide at least a handle 49 to allow easy removal of the burner assembly 17.

[0129] The coupling device 50 includes one or more magnetic elements 52 positioned to attract and retain the bracket 46 at a coupling location 54 on the base 28. More specifically, in the depicted embodiment, the coupling device 50 includes a series of spaced-apart magnets 55 located at or below the base 28 at the coupling location 54, and each bracket 46 includes a leg 53 with a foot 56 adapted to be magnetically attracted to the series of magnets 55. The legs 53 are spaced at the same (or substantially similar) distance as the one or more magnetic elements 52 so that the burner assembly 17 is attracted to a preferred assembly position and self-positioned with the one or more magnetic elements 52. However, it should be understood that the coupling device having spaced-apart magnets can be located at any suitable location on the body 14 or the interior cavity 16.

[0130] In more detail, the legs 53 and / or feet 56 can be made entirely or partially of a ferritic metal, such as, but not limited to, ferritic stainless steel 443. The series of magnets 55 can be any suitable magnet, but are preferably rare earth magnets. It should be noted that in some examples, the configuration of the coupling device 50 can be reversed, with the legs 53 carrying the magnetic element 22 and the inner cavity 16 including the magnetically attractive material 220 (e.g., Figure 12 and 14 This article considers these two examples.

[0131] The above configuration allows the burner assembly 17 to be manually removed via the handle 49 by releasing the coupling 50 and also disconnecting the gas port 42. The coupling 50, which in this case is magnetic, allows the interior cavity 16 to remain relatively clear of obstructions and provides a substantially smooth and rounded integral surface 34. Thus, when the burner assembly 17 is removed, the interior cavity 16 can be easily accessed for cleaning, for example using a fluid, such as water, directed to the drain tube 32. In this case, the coupling 50 is magnetic, also allowing for simple, tool-free removal of the burner assembly 17, and the arrangement of the bracket 46 and the series of magnets 55 allows the burner assembly 17 to be substantially self-locating when assembled.

[0132] refer to Figure 5It should be understood that the cooking device 10 may optionally include a pair of rotisserie brackets 94 and a rotisserie motor 95 that can be connected to a rotisserie rod (not shown). The rotisserie motor 95 is operable to drive the rotation of the rotisserie rod to cook food attached to the rod. The rotisserie brackets 94, motor 95, or other accessories can be coupled to the body 14 (e.g., surface 61) via one or more magnets 59. As described above, one or more magnets 58 are used to couple one or more metal tabs 23a of the flame tamer 23 to the body 14. It should be understood that the concepts of the coupling device 50 including the magnets 55, 58, or 59 described above can be integrated into any embodiment of the cooking device described herein.

[0133] The grill 12 may also include a channel 60 arranged to direct fluid, particularly bulk fluid (e.g., cleaning fluid), from the discharge pipe 32 to a reservoir 62 providing a collection point 64. Figure 7 In the illustrated embodiment, the reservoir 62 is shown as a large can or bucket, but it will be understood that the reservoir 62 can be any suitable size or shape to hold the fluid. The reservoir 62 can also include a cover or shroud 65 to cover the upper opening of the reservoir 62. The channel 60 can be releasably coupled to the bottom 28 and extend toward one side of the body 14. It will be understood that various components of the cooking apparatus 10, such as, but not limited to, the channel 60, the burner assembly 17, or the cooking surface 20, can be of a suitable size and / or shape to be installed in a dishwasher for cleaning purposes. The removable cover 22 can also be connected by an additional coupling device 70, which also includes an additional magnetic element 72 connected to the body 14 and a magnetically attractive connecting piece 74 pivotally connected to the cover 22.

[0134] To aid in cleaning, cooking apparatus 10 may include a water source (e.g., Figure 7 A hot water module 80 is shown, the water source being arranged to provide water to the inner cavity 16, for example through a water outlet located in or near the inner cavity 16, or a manual water source 82, such as a hand shower, washer, sprayer or the like. Figure 7 In the embodiment shown, the manual water source 82 is a handheld sprayer or shower having a length of hose 83 connected to the hot water module 80. Thus, the manual water source 82, when activated, can be supplied with hot water to aid in cleaning the grill 12. The hot water module 80 can be in the form of an instantaneous water heater that is incorporated to supply hot water to the interior cavity 16. The hot water module 80 can also be in the form of a steam unit and can be externally powered. The hot water module 80 can use the same gas supply as the burner or an alternative energy source such as an electrical supply. For example, and also as Figure 7As shown, the cooking device 10 may include a gas cylinder 84 having a regulator 86 and a diverter hose 88. A first end 90 of the diverter hose 88 is connected to the internal cavity 16 (e.g., the gas manifold of the grill 12), and a second end 92 of the diverter hose 88 is connected to the hot water module 80. The hot water module 80 can be supplied with cold water via a hose connector or inlet 89 or other connection means, such as a domestic water supply such as a garden faucet. It should be understood that the concept of a water source, such as the hot water module and manual water source described above, can be integrated into any of the embodiments of the cooking device described herein.
