The present application claims the benefit of Honk Kong Application No. 18106228.1, filed May 14, 2018, and is related to U.S. Application 29/625,563, filed Nov. 10, 2017; the aforementioned applications are incorporate herein by reference in their entirety.
The present disclosure relates to the field of a gas range, and more particularly a gas range for installing in a counter and/or for use in a vehicle.
Vehicles such as, for example, an automobile, an airplane, a watercraft, etc. are becoming more and more sophisticated and luxurious. Larger vehicles, especially luxurious larger vehicles such as yachts, recreational vehicles (RVs), including mobile homes, motor homes, caravans, trailer homes etc., are increasingly expected to contain the comforts one finds in larger, sedentary homes. This increasingly includes comforts such as full ranges having both an oven and a cooktop (i.e., a burner for cooking). See, for example, US Design Patent Application No. 29/625,563 to Bell, filed on Nov. 10, 2017 entitled OVEN, and U.S. patent application Ser. No. 15/368,057 to Bell, filed on Dec. 2, 2016, entitled COOKING GAS APPLIANCE, both of which are incorporated by reference herein, in their entireties.
However, as compared to a sedentary home, a vehicle possesses certain limitations with respect to energy, space, etc. While electric burners and electric ovens are possible the electrical energy requirements of an electric oven and/or an electric cooktop may be prohibitive, especially if the vehicle is not connected to the electrical power grid. Typically, the only electricity that is available may come from a 12-volt DC battery system. Therefore, devices for use in vehicles such as a RV should not generally have a high power rating and/or energy consumption. Accordingly, many larger, luxury vehicles employ a gas range utilizing a gas, such as propane gas, butane gas and/or natural gas; or propane gas, for cooking, baking, etc.
Furthermore, very strict regulations exist for the use of gas and other cooking technologies, especially gas cooking, in vehicles. This is because without sufficient room and access for adequate combustion, it is possible that toxic and/or noxious fumes could be generated and cause health or other issues. For example, please see American National Standard Institute's Standard for Recreational Vehicle Cooking Gas Appliances, ANSI Z21.57-2010, and the addenda ANSI Z21.57a-2012. Such standards seek to increase consumer safety by reducing the risk of, for example, carbon monoxide (CO) poisoning due to incomplete combustion of propane and other gases.
Furthermore, as space is often at a premium in a vehicle, for example, a recreational vehicle, a boat, an airplane, etc., often the counter or countertop is needed for multiple tasks such as cleaning, cooking, storage, etc. Therefore, having a large cooktop taking up a large surface area may be considered a waste of space in such a vehicle. Such needs may also exist in, for example, a small apartment or studio.
In addition to taking up needed counter space, the upper surface of a cooktop often juts above the surface of the countertop, thereby making it more difficult to clean, more difficult to easily utilize the existing counter space, etc.
In addition, the space provided for a gas range is often limited and yet users and owners wish to have as large an oven as possible, for example, sized so as to accommodate and bake a large ham and/or turkey for festive occasions.
Accordingly, there exists a need to increase the usable countertop surface area within a vehicle. Furthermore, it is desirable to be able to provide increased counter space while also meeting the relevant carbon monoxide standards.
An embodiment of the present disclosure relates to a gas range containing a gas range height. The gas range contains an oven having an oven cavity, and a cooktop located above the oven. The cooktop contains a gas burner having a gas burner height, and a cooking grate above the gas burner. The cooking grate has a cooking grate height. A gas oxidation height is the difference between the cooking grate height and the gas burner height. The gas oxidation height is from about 10 mm to about 40 mm; or from about 13 mm to about 35 mm, or from about 15 mm to about 30 mm; or from about 20 mm to about 29 mm. The gas range height is from about 350 mm to about 450 mm; or from about 375 mm to about 425 mm; or from about 390 mm to about 410 mm.
A gas range contains an oven, a cooktop and a lid. The oven contains an oven cavity and a plurality of oven exhausts. The cooktop contains a gas burner and a cooking grate above the gas burner. The lid covers the cooking grate and the lid has an open position and a closed position. An oven exhaust leads from the oven cavity to the cooktop and when the lid is closed the lid forms a flat top.
An embodiment of the present disclosure also relates to a counter containing the gas range as described herein, or a counter containing the gas range described herein installed into the counter.
An embodiment of the present disclosure relates to a vehicle containing the gas range described herein, or the counter described herein.
Without intending to be limited by theory, it is believed that the present disclosure provide a balance between maximizing oven space and yet still providing a flat top gas range. It is believed that by optimizing the height of the gas oxidation height, the gas range herein may provide one or more benefits such as, for example, a maximized oven height, complete combustion and approval according to Z21.57-2010, and the addenda ANSI Z21.57a-2012, a flat top gas range, a gas range which is substantially flush with the countertop, a significantly greater counter space, etc.
Aspects of the present disclosure will now be described in further detail by way of example with reference to the accompanying drawings, in which:
It should be understood that the drawings are not necessarily to scale. In certain instances, details that are not necessary for an understanding of the disclosure or that render other details difficult to perceive may have been omitted. It should be understood, of course, that the disclosure is not necessarily limited to the particular embodiments illustrated herein.
Unless otherwise specifically provided, all tests herein are conducted at standard conditions which include a room and testing temperature of 25° C., sea level (1 atm.) pressure, pH 7, and all measurements are made in metric units. Furthermore, all percentages, ratios, etc. herein are by weight, unless specifically indicated otherwise.
As used herein, the term “flat top” indicates that when the lid herein is in the closed position, the lid, or a surface attached to the lid, forms a flat surface which allows the area to be used for storage, placing a cutting board, chopping, etc. in effect extending the useable surface area as if it was part of the countertop. While the surface formed by the lid need not be perfectly flat (see, for example, the hinges that slightly protrude from the flat top formed by the lid in
As used herein, the term “gas range” indicates a combination of an oven and a gas cooktop. The oven may be a gas or electric oven; or a gas oven. The cooktop is a gas cooktop and contains at least one burner for combusting a gas, typically propane gas, to create a fire for cooking. Gas ranges are generally well-known in the art and are present in buildings, such as houses, as well as vehicles such as an automobile, an airplane, a watercraft, etc.; or a recreational vehicle, a boat, a submarine, an airplane, and a combination thereof.
As used herein, the “gas burner height” indicates the height between the base of the cooktop and the top of a gas hole, where the gas exits the burner for combustion.
An embodiment of the present disclosure relates to a gas range for a vehicle, where the gas range contains a gas range height. The gas range contains an oven having an oven cavity, and a cooktop located above the oven. The cooktop contains a gas burner having a gas burner height, and a cooking grate above the gas burner. The cooking grate has a cooking grate height. A gas oxidation height is the difference between the cooking grate height and the gas burner height. The gas oxidation height is from about 10 mm to about 40 mm; or from about 13 mm to about 35 mm, or from about 15 mm to about 30 mm; or from about 20 mm to about 29 mm. The gas range height is from about 350 mm to about 450 mm; or from about 375 mm to about 425 mm; or from about 390 mm to about 410 mm.
Without intending to be limited by theory, it is believed that the gas oxidation height herein represents the minimum height needed in order to provide sufficient combustion so as to pass the ANSI test described herein. It is believed that when a cooking implement such as a pot or a pan is placed on the cooking grate, the distance between the top of the gas hole through which the gas passes and the bottom of the cooking implement must be sufficient so as to allow air to mix with the gas and create sufficient combustion to avoid carbon monoxide formation. Without intending to be limited by theory, it is believed that if the gas oxidation height is too short, then this increases the chance that carbon monoxide will form. While a higher/taller gas oxidation height is possible, it is believed that this results in either a gas range which protrudes above the counter too much or a shorter over cavity height; both of which are undesirable.
An embodiment of the present disclosure also relates to a counter containing the gas range as described herein, or a counter containing the gas range described herein installed into the counter.
An embodiment of the present disclosure relates to a vehicle containing the gas range described herein, or the counter described herein.
Accordingly, it is believed that by optimizing the height of the gas oxidation height, the present disclosure safely provides one or more benefits such as, for example, a maximized oven height, complete combustion and approval according to ANSI Z21.57-2010, and the addenda ANSI Z21.57a-2012, a flat top gas range, a gas range which is substantially flush with the countertop, a significantly greater counter space, etc. It is further believed that the present disclosure successfully balances the competing desires to maximize oven space and yet still provide increased counter space by providing a flat top gas range.
Such a flat top gas range may increase available and usable counter space by providing another surface to prepare food, place/store items, etc. In such a situation, it is preferred that the gas range herein contain a lid for covering the cooking grate. The lid may possess an open position and a closed position. When the lid is in the closed position, the gas range contains a closed lid height. In an embodiment herein, the closed lid height is substantially the same as; or level with, the gas range height; or is from about 0 to about 10 mm higher than the gas range height; or from about 0 to about 5 mm higher than the gas range height; or from about 0 to about 3 mm higher than the gas range height.
In an embodiment herein, the oven cavity contains an oven cavity height. As the oven cavity is typically a square or a rectangle, the oven cavity height is typically quite uniform regardless of where it is measured. However, in case the oven cavity height is not uniform, then as used herein, the oven cavity height is considered to be the longest distance available within the oven cavity, when measured perpendicular to the base of the gas range. As mentioned herein, it is desirable to maximize the height of the oven cavity as it allows a larger cooking volume and also may allow the baking of, for example, a chicken, a roast, a rack of ribs, a turkey, etc. therein. Furthermore, a large oven may be considered a significant indication of luxury. Accordingly, in an embodiment herein, the oven cavity height is from about 150 mm to about 310 mm; or from about 170 mm to about 280 mm; or from about 200 mm to about 260 mm.
In addition, it is believed that when the oven appears larger, then it again reinforces the image of a luxury appliance. Accordingly, in an embodiment herein the oven has an oven height. It an embodiment herein, the percentage of the oven height with respect to the gas range height is from about 25% to about 99%; or from about 45% to about 98%; or from about 60% to about 95%; or from about 65% to about 90%.
Similarly, it is desirable to have as wide of an oven cavity as possible, and therefore in an embodiment herein, the oven cavity has an oven cavity width of from about 500 mm to about 250 mm; or from about 450 mm to about 300 mm; or from about 400 mm to about 350 mm. Similarly, it is desirable to maximize not just the width of the oven cavity, but to also maximize the width of the oven cavity with respect to the gas range. Accordingly, in an embodiment herein, the gas range has a gas range width, and the percentage of the oven cavity width with respect to the gas range width is from about 25% to about 99%; or from about 45% to about 98%; or from about 60% to about 95%; or from about 65% to about 93%.
In an embodiment herein, the oven contains a door to seal the oven cavity. The door may typically have a glass window or other heat-resistant transparent layer to allow the user to see into the oven when it is cooking.
Typically propane gas, butane gas, natural gas, and a combination thereof; or propane gas is used for cooking in a gas range. Such a gas is typically contained in a pressurized bottle, or other storage container. In certain cases, the gas may be stored as a liquid in a pressurized container, and operatively-connected to the gas range. The gas range typically also has an electrical spark which provides an ignition for the gas so that it can be used. In an embodiment herein, the gas range further comprises a gas feed configured to provide a gas for cooking with the gas range, wherein the gas is at least one gas chosen from propane gas, butane gas, natural gas, and a combination thereof.
In an embodiment herein, the cooktop is a gas cooktop, while the oven may be either an electric oven, a gas oven, a microwave oven, and a combination thereof. In an embodiment herein, the cooktop is a gas cooktop and the oven is a gas oven.
As mentioned herein, an embodiment of the present disclosure relates to a counter; or a countertop, having the gas range installed therein. In the case of a vehicle containing the gas range or the counter; or countertop herein, the installation may occur at the factory, at a dealership, or afterwards. In order to maximize counter space and the aesthetics of the counter, in an embodiment herein, the counter has a level surface, and the gas range is installed into or adjacent to the level surface. The gas range (including the lid) may protrude from the level surface (i.e., the gas range rises above the counter) a maximum distance of from about 0 mm to about 20 mm; or from about 0 mm to about 10 mm; or from about 0 mm to about 5 mm. In an embodiment herein, the gas range may lie below the level surface of the counter a maximum distance of from about 0 mm to about 20 mm; or from about 0 mm to about 10 mm; or from about 0 mm to about 5 mm. Without intending to be limited by theory, it is believed that the top of the gas range should be as close as possible to the level surface of the countertop so as to improve the utility of the gas range. In an embodiment herein, the lid; or the flat top, is substantially level with the countertop if installed therein or adjacent thereto.
In an embodiment herein the lid; or the highest portion of the lid is substantially even with the level surface of the counter, meaning that the height variance is from about 0 mm to about 20 mm; or from about 0 mm to about 10 mm; or from about 0 mm to about 5 mm. In an embodiment herein the lid has an open position and a closed position, and may pivot between these positions via, for example, one or more lid hinges. In an embodiment herein, a lid hinge; or a plurality of lid hinges, is/are located in the rear of the lid and/or the cooktop, and a lid hinge; or each hinge, contains a spring. The spring biases the lid hinge so as to allow the lid to be more easily moved into the open position and/or the closed position. In an embodiment herein, the spring and the lid hinge bias the lid into the open position, the closed position, or both the open position and the closed position providing, respectively, a bias selected from the group of an opening bias, a closing bias, and a combination thereof. In an embodiment herein, when the lid reaches a predetermined angle, then because of the bias, the spring and lid hinge automatically move the lid to either the open or closed position. For example, if the opening bias is predetermined for when the lid is opened to about 60°, then when the lid is at an angle of more than 60°, then the lid will more easily flip up into the open position; or flip up into the open position. If, for example, the closing bias is predetermined for when the lid is closed to about 30°, then when the lid is at an angle of less than 30°, then the lid will more easily settle into the closed position; or settle into the closed position. In an embodiment herein, the bias is provided by a locking mechanism.
Without intending to be limited by theory, it is believed that a bias, especially an opening bias, may, for example, reduce the likelihood of accidents caused by the lid moving; or closing, while the gas burner(s) is/are in use, and/or an object is placed on the cooking grate. Such a feature may be especially useful in the case where a gas range is being used in a vehicle while it is moving.
In an embodiment herein, a vehicle contains the gas range or the counter herein. The vehicle may be selected from the group of an automobile, an airplane, a watercraft, and a combination thereof; or a recreational vehicle, a boat, a submarine, an airplane, and a combination thereof. In an embodiment herein, the recreational vehicle is selected from a mobile home, a motor home, a caravan, a trailer home, etc.
In an embodiment herein, the oven contains at least one oven exhaust; a plurality of oven exhausts; or from about 2 oven exhausts to about 10 oven exhausts; or from about 2 oven exhausts to about 5 oven exhausts; or from about 2 oven exhausts to about 3 oven exhausts. In an embodiment herein the oven exhausts lead from the interior of the oven cavity to the cooktop; or the area above the cooktop. The oven may further contain a vent; or a plurality of vents; or the same number of vents as oven exhausts, on the cooktop or positioned adjacent to the cooktop. Without intending to be limited by theory, it is believed that a plurality of oven exhausts allows the oven to possess a more even/uniform temperature therein, as opposed to an oven containing only a single, large exhaust. For example, one who is used to baking understands and has experienced the situation where, even with a convention oven, the front of the oven is oftentimes hotter than the back of the oven, which may primarily be due to a large vent in the back of the oven cavity. It is believed that by having a plurality of (smaller) oven vents, the temperature in the interior of the oven cavity may be more uniform.
In an embodiment herein, the cooktop is removable from the gas range. Without intending to be limited by theory, it is believed that this may, for example, make the installation, cleaning and/or dismantling of the gas range significantly easier. In an embodiment herein, the cooktop may be removable by lifting the rear of the cooktop up and away from the gas oven, while pivoting the front of the cooktop on the front of the oven. In an embodiment herein, the rear of the cooktop contains a locking mechanism; or a friction-lock, which keeps the cooktop locked to the gas oven unless a significant amount of force is applied. Without intending to be limited by theory, it is believed that this prevents the cooktop from dislodging from the gas oven unless it is purposely removed.
