[0016] Steaming devices, such as those disclosed in EP Patent No. 1775216, GB patent No. 2307974 and JP patent No. 10234352 may enable steaming of various items. For example, EP patent No. 1775216, discloses a steaming device for food trays in which steam is delivered to the trays via air circulating ducts to moisten and warm the trays. While these devices operate satisfactorily, they do not afford simple and efficient polishing of a plurality of glasses or eating utensils.

[0017] Referring first to FIGS. 1 through 3, the steaming device 2 according to the invention will now be described. The device is particularly suitable for steaming utensils such as glassware and silverware, but can also be used to steam pots, pans, bowls and other kitchen implements used in the food service industry. As illustrated in FIG. 1, the device 2 includes a frame 4 having side walls 8 that may form a ledge 6 establishing an inner perimeter of the frame 4 being open at its upper and bottom ends and creating a frame opening 16. In some embodiments, the edge and/or upper surface of the ledge 6 may be lined with a padding material, such as silicone, foam, or rubber. The side walls 8 may also have frame flanges 10 that protrude horizontally outward from the upper surface of the side walls 8. The frame flanges 10 do not meet at their ends to create corners, rather they create frame gaps 12. The frame gaps 12 may be notches or other type openings that provide a horizontal surface below the horizontal plane of the frame flanges 10. The side walls 8 may be equal in length to form a square frame 4. In other embodiments, the side walls 8 may be different lengths to form a non-square frame 4, such as a rectangular frame.

[0018] Arranged beneath the frame 4 is a heating deck 24. The heating deck may have opposing containment walls 28 adjacent to opposing loading walls 26 to assist in retaining one or more heating devices. As shown in FIG. 3, the loading walls 26, which may be shorter in height than the containment walls 28, are designed so the heating device can be positioned and removed from the heating deck 24 with ease while providing a restraint to inadvertent discharge of the heating device. In an embodiment of the invention, the heating device may be one or more portable and replaceable canisters 22 containing a flammable composition which may be activated when the device is in use and extinguished when not in use (e.g., a Sterno cooking fuel can). Any number of portable and replaceable canisters 22 may be used, such as one, two, three, four, five, or more portable and replaceable canisters 22. The height of the loading walls 26 and containment walls 28 also may be designed to allow air to circulate to the heating device, such as canister 22, for purposes of combustion. Other suitable heating devices such as one or more electric coils or one or more gas burner may also be used for the heating devices on the heating deck 24.

[0019] A plurality of legs 18 connect the frame 4 to the heating deck 24. In particular, the plurality of legs 18 connect the plurality of frame side walls 8 to the loading and containment walls of the heating deck 24 by fasteners 20. The fasteners 20 may include welding methods, molding methods, soldering, screws, bolts and nuts, or rivets. The steaming device 2 may be formed of any suitable rigid material such as metal and/or synthetic plastic.

[0020] As illustrated in FIGS. 2 and 3, a fluid reservoir 30, 38 may be arranged within the frame 4, having a plurality of side walls 34, 42 extending from the frame side walls 8 toward the inner perimeter of the frame 4 and toward the heating deck 24 and enclosed by a reservoir bottom 32, 40. When inserted into the frame 4, the fluid reservoir 30, 38 may extend past the ledge 6 or may not extend past the ledge 6. When inserted into the frame 4, the fluid reservoir 30, 38 may extend toward the heating deck 24 and below the horizontal plane created by the bottom of the side walls 8 or the fluid reservoir 30, 38 may not extend below the horizontal plane created by the bottom of the side walls 8.

[0021] Preferably, the bottom 32, 40 of the fluid reservoir 30, 38 may be formed of a heat transmissive material such as metal to effectively conduct heat from the heating device to a fluid, preferably water, arranged in the reservoir. The fluid is heated by the heating device to generate steam which exits the fluid reservoir 30, 38 through the open frame opening 16. The fluid reservoir 30, 38 may be any shape. For example the fluid reservoir 30, 38 may be configured as a trapezoidal fluid reservoir 30, 38 where a top opening of the fluid reservoir 30, 38 is larger than the bottom 32, 40 as caused by the sloping of the walls of the fluid reservoir 30,38 away from the bottom 32,40. While illustrated as a square, fluid reservoir 30, 38 may be any shape, such as a square, rectangle, etc., and the shape of the fluid reservoir 30, 38 may be selected to match the shape of the frame 4.

[0022] In an embodiment of the invention, a fluid reservoir 30 is a top suspended reservoir having reservoir walls 34 with reservoir flanges 36 that protrude horizontally outward from the upper surface of the reservoir walls 34. The reservoir flanges 36 may, for example, meet together at a corner 37 or may stop short of forming a corner as both are illustrated in FIG. 2. The reservoir flanges 36, when laid upon the frame flanges 10, suspend the reservoir above the heating deck 24, and the corner 37 embodiment may make it easier to remove the reservoir from the frame 4. In such an embodiment where the reservoir flanges 36 are laid upon the frame flanges 10, the edge 6 establishing an inner perimeter of the frame 4 may be optional as the fluid reservoir 30 may be fully supported by the frame flanges 10.

[0023] In another embodiment, a fluid reservoir 38 is a side suspended reservoir having reservoir walls 42 adjacent to the inside of the frame walls 8 extending toward the inner perimeter of the frame 4 and suspended by the ledge 6, and having a reservoir bottom 40 as illustrated in FIG. 3. In this embodiment, each of the opposed frame side walls 8 of the frame 4 preferably contain an opening 14 which a user may use to lift the frame 4. In addition, the openings 14 provide an alternate way for adding fluid to the fluid reservoir 38 as will be discussed below. The fluid reservoir 38 may be similar to fluid reservoir 30, except that the reservoir walls 42 and reservoir bottom 40 may be configured such that the fluid reservoir 38 may has a perimeter that is smaller than the perimeter of the opening defined by the side walls 8. In this manner, the fluid reservoir 38 may fit entirely within the side walls 8 and be supported by the ledge 6. In some embodiments, the fluid reservoir 38 may have reservoir walls 42 tapered toward the reservoir bottom 40 from the top opening of the fluid reservoir, for example in the general shape of a trapezoid. The top opening of the fluid reservoir 38 may have a perimeter larger than the inner perimeter of the opening defined by the ledge 6 and may be supported by the ledge 6, such as by friction of the ledge 6 against the reservoir walls 40 and/or by a lip or other protrusion of the fluid reservoir 38. FIG. 6 illustrates a fluid reservoir supported in such a manner within the frame of the steaming device 2.

[0024] Referring now to FIGS. 4 and 5, a stackable tray or rack or 44 for holding a plurality of utensils will now be described. The rack includes a bottom wall 46 in the form of a grate containing a plurality of openings 48 and a plurality of side walls 50 connected with the bottom wall. The side walls are preferably solid without any openings. The top of the rack is open to receive a plurality of utensils such as glasses 52 which fit into compartments defined by interior walls 54 of the rack. The racks are preferably formed of a lightweight rigid material such as synthetic plastic. Other types of racks with different interior configurations may be provided to receive silverware, bowls, plates, pans, or other kitchen utensils which are to be steamed for polishing.

[0025] The steaming device 2 is designed to support one or more racks, such as a plurality of stackable racks as shown in FIG. 6. The steaming device 2 may support 1, 2, 3, 4, 5, or more racks stacked on one another. Preferably, the reservoir flanges 36, which are laid upon the frame flanges 10, or the frame flanges 10 are configured to mate with the bottom peripheral edge of the racks 44. This allows a plurality of racks to be stacked on the device. With water arranged in the fluid reservoir of the steaming device 2, the heating elements on the heating deck 24 are activated to heat the water and generate steam. The steam rises from the device 2 and is transported through a column of stacked racks defined by the solid side walls of the racks. With each rack containing a plurality of utensils, the utensils can be uniformly warmed and steamed simultaneously with a higher level of sanitation and less water waste than is obtained with prior steaming devices and practices. This insures that the utensils can be polished more effectively by the kitchen staff. In addition, the openings 14 in the side walls of the device 2 afford an alternate venue for replenishing the water in the fluid reservoir.

[0026] The steaming device 2 may fit on a standard glassware/silverware trolley or cart 56 which has wheels 58 which allow the entire assembly shown in FIG. 6 to be easily transported from a kitchen to a dining area so the dining tables can be set with freshly cleaned utensils. Alternatively, wheels may be affixed directly to the steaming device 2 itself, such as on the legs 18. The bottom of the steaming device 2 has legs 18 that may be configured to engage with an upper peripheral edge of the racks 44 to elevate the steaming device 2 on top of the rack 44. Elevating the device 2 by e.g., one to four racks height above the floor level mitigates floor drafts, and makes it easier for the user to access the heating deck 24 to replace fuel canisters 22 or to add water to the fluid reservoirs 30, 38.

[0027] The preceding description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the claims. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the claims. Thus, the present disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the following claims and the principles and novel features disclosed herein.
