The invention relates to cooking appliances. More specifically, the invention relates to lids for cooking appliances, such as grills.
It is well known that use of a lid over a cooking appliance such as a grill is beneficial in numerous ways. For example, a lid over a grill serves to retain heat resulting in more evenly cooked food from the grill. Also, the lid protects the area surrounding the grill from food splatter—resulting in a cleaner cooking area. These advantages are also desired for other appliances such as griddles and ranges. For a variety of reasons, lids on cooking appliances are desirable.
In some cooking environments, however, it is not possible to install a solid lid on a cooking appliance. On boats, for example, space is extremely limited and purpose driven. This is particularly true for space above-decks outside the cabin. Outdoor kitchens installed on a boat typically include a large enclosure for covering and protecting the sink, grill, and other components of the kitchen. While the boat is under way, the enclosure is closed, but, while the boat is at anchor, the enclosure can be opened to permit use of the kitchen.
The enclosure is usually designed so that the kitchen has a low profile, which has the consequence that there is not sufficient room under the enclosure to accommodate a traditional cover for the grill. As a result, the cover is not permanently installed on the grill (such as by a hinge), but, instead, is completely detached so it can be stowed elsewhere on the boat when the enclosure is closed. This arrangement has significant disadvantages, as the cover can be lost, dislodged during use, damaged, etc.
Next, traditional cooking appliance lids are constructed using highly thermally conductive materials, such as stainless steel or other metals. These materials can become extremely hot to the touch while the appliance is in use, which can be dangerous, especially for children. These materials also do not provide good retention of cooking heat generated by the appliance, resulting in a less efficient appliance.
What is needed, therefore, is a cooking appliance cover adapted to accommodate the demands of tight spaces where a low profile is needed. A cover is needed that will provide the benefits of traditional cooking appliance covers but will be capable of assuming a low profile so that it need not be detached from the appliance. What is further needed is a cover that is safe to touch, even while the cooking appliance is in operation.

In one advantageous embodiment, the collapsible portion of the cover is made of a silicone-based rubber, which has the beneficial properties of very high resilience and is stable at relatively high temperatures. It is also an excellent thermal insulator. Covers formed of silicone rubber tend to retain the heat of the cooking appliance much more efficiently than traditional metal lids.
In a particularly advantageous embodiment, the collapsible portion 3 is made of a silicone rubber that permits users to see objects and food underneath the cover on the cooking appliance. Such a silicone rubber is typically highly translucent or transparent.
In the embodiment shown in
The grill 2 includes a housing that is inserted into an opening in the kitchen fixture 10. The housing has a coupling member for retaining the grill housing in the opening. In the embodiment shown in
The grill further includes controls 9 positioned on any side of the housing for turning the heating surface on and off and for controlling the temperature of the heating surface. It is understood that the cover of the present invention may be used with any type of a grill, including electric, gas or charcoal grill. Additionally, the cover may be used with induction heat grills, which are heated by induction current. Examples of induction grills are described, for example, in US 2012/0132645 to Oh et al. and U.S. Pat. No. 8,695,488 to Liu, the disclosure of which is incorporated herein in its entirety. Further, the cover is also suitable for use with other cooking devices, such as cooktops, hotplates, etc.
In the collapsed configuration shown in this figure, the height of the cover 1 is roughly one quarter of the height when it is not collapsed. The collapsed height varies depending on the specific embodiment and use for particular applications, and includes any reduction in height from the uncollapsed height.
In some embodiments, a cooking appliance, such as a drop-in grill, is supplied with a low-profile enclosure and a collapsible cover that folds underneath the enclosure. Such an embodiment has the advantage of providing an attractive appliance as well as the improved functionality of a highly thermally insulating lid. In such an arrangement, the insulating cover is attached to the appliance in a manner similar to that shown in
The boat kitchen 110 further includes a large hard enclosure 112 for covering and protecting various components of the kitchen. The enclosure is connected to the base portion 120 by any suitable mechanism that allows the enclosure 112 to be opened and closed easily. While the boat is under way, the enclosure 112 is closed, but, while the boat is at anchor, the enclosure can be opened to permit use of the kitchen 110.
The enclosure 112 is usually designed so that the kitchen has a low profile. The collapsible cover 116 of the present invention can be permanently secured adjacent the grill 114 even though the enclosure 112 provides a low-profile while the kitchen is covered. As shown in
The collapsible portion 152 has weakened portions that assist it in folding into its collapsed state. Such weakened portions comprise specifically selected areas of thinner material. The locations of the weakened portions are selected to encourage the forming of folds in the collapsible portion 152 during collapse. The thinness of the material in the weakened portions facilitates these folds. The use of the weakened portions ensures that the collapsible portion 152 of the cover 150 will collapse in the same way and to the same depth consistently each time it is collapsed.
In the embodiment shown in
As seen in
The cover 200 has a generally rectangular shape with slightly curved edges. The cover includes a molded silicone collapsible portion 214, a frame 216, and another handle 212 positioned on the front bottom portion of the cover. It is understood that any other suitable thermally insulating material may be used for the collapsible portion 214. The second handle 212 is used to tilt the cover 200 to partially open it such that food items can be observed inside without having to remove the cover entirely. As shown in
While the exemplary embodiment shown in
The collapsible portion 214 of the cover 200 includes a plurality of weakened portions 218, as illustrated in the underside view of the cover in
In this embodiment, the cover 200 further includes a plurality of slits 220 formed in the walls of the collapsible portion 214. In the embodiment shown in
When a downward force is exerted on the cover 200, the collapsible portion 214 of the cover collapses along the weakened portions such that the cover is brought into a collapsed configuration. The height of the cover, when in the collapsed configuration, is less than the height of the cover in a working configuration. If the cover 200 is used in a setting wherein there is a hard enclosure covering a cooking device, such as, for example in a boat kitchen, as described above, the height of the cover 200 in the collapsed state is such that it fits under the enclosure when the enclosed is in a closed position.
The pull-out drawer 310 has an opening that houses a drop-in cooking device 312. In the embodiment shown in this figure, the cooking device is a drop-in grill. However, it is understood that any other cooking device may be used in accordance with the invention. In addition, the pull-out drawer may include other components of a mobile kitchen, such as, for example, a sink, a cutting board, etc.
The grill 312 includes a collapsible cover 318 positioned over the heating element of the grill. In the embodiment shown, the collapsible cover 318 is hingedly attached to the grill adjacent the heating surface of the grill. In other embodiments, the collapsible cover is not attached to the grill, but is a separate element that is placed over the grill. The collapsible cover 318 has any of the structures discussed above.
The cover is capable of being stored inside the pull-out drawer 310 when the drawer is closed because the height of the cover in its collapsed configuration is such that it fits inside the closed drawer. When in use, the drawer 310 is pulled out from the RV wall and the collapsible cover 318 is placed in its working fully expanded configuration. This may be done automatically when the drawer is opened, for example is the collapsible portion of the cover is made with resilient material that will spring from its collapsed configuration to the expanded configuration once the drawer is opened. Alternatively, a user may manually place the cover in its extended configuration once the drawer is pulled out. The cover is then used to cover the heating surface of the grill during cooking.
After cooking is finished and the grill is turned off, the cover 318 is collapsed by exerting a downward force on it. This is done by manually pressing the top of the cover until it is collapsed. In other embodiments, the cover 318 is collapsed automatically when the drawer 310 is pushed back into the RV wall by exerting a downward force on the top surface of the cover via the top wall of the enclosure into which the drawer is pushed.
Although not shown in this figure, the pull-out drawer may include a hard enclosure that covers the grill for safety and aesthetic appeal when not in use. If the drawer has a hard enclosure, the collapsible cover 318 may be brought to its collapsed storage configuration by simply closing the hard enclosure over the grill, thereby exerting a downward force on the top of the cover. In this embodiment, the height of the cover 318 when in collapsed configuration is such that it fits under the enclosure when the enclosure is in a closed position.
The grill includes a collapsible cover 416. The cover may be of any configuration described above. In the embodiment shown in
In additional embodiments, the cover 416 may be attached to the grill. After the use of the grill, the cover 416 may be brought to its collapsed configuration by placing the countertop piece over it to exert a downward force on the top of the cover. In these embodiments, the height of the cover 416 when in collapsed configuration is such that it fits under the countertop piece once it is placed over the grill.
In some embodiments, the collapsible cover of the present invention can be retrofit onto a cooking appliance that originally included a traditional rigid cover. This arrangement permits the user to choose between a traditional cover and the collapsible cover of the present invention.
It should be understood that the foregoing is illustrative and not limiting, and that obvious modifications may be made by those skilled in the art without departing from the spirit of the invention. Accordingly, reference should be made primarily to the accompanying claims, rather than the foregoing specification, to determine the scope of the invention.
