Abstract

An oven with interior surfaces containing multiple heating elements allows for the division of said oven into various compartments. These compartments are formed by insulated partitions, positioned in either a horizontal or vertical orientation. Grooves on both these insulating dividers and interior surfaces of the oven allow for the insertion of oven racks and additional dividers. Each individual heating element is controlled independently to allow for compartmentalized and simultaneous cooking of different food items, and increased energy savings.

Description

MULTIPLE COMPARTMENT OVEN
INVENTORS:
Eckert, David Komm, Kristopher Gebreselassie, Mekdes FIELD
The present invention relates to an electric oven and the use of removable insulated dividers and multiple heating elements to compartmentalize the interior oven cavity, where the design allows for the heating of each oven compartment to be controlled independently of one another.
BACKGROUND
NOTE: Let it be noted that while the background section describes the function, usage, and problems associated with the conventional electric oven and recent inventions of others, the invention that is presented here is intended to encompass any form of oven or cooking apparatus for which heating elements are used and there is a possibility for division of said apparatus into a multitude of independently controlled compartments.
Electric ovens are primarily used for the purpose of cooking various baked goods. Electric stove ovens are now common kitchen appliances in most modern households. A wide range of sizes of these ovens exist, leading to a range of cooking capacity for each. An electric range combined oven for home use has, on average, a volume of approximately 6.3 cubic feet [1]. The daily operation of an oven can lead to significant energy costs depending on its capacity, temperature settings, and its level of efficiency
[2]. The use of large capacity ovens to cook small food portions results in substantial energy loss and unnecessarily high electrical bills. As a solution, some homeowners own an additional oven with a relatively small capacity to use for cooking small amounts of food.
Electric ovens normally have one interior cavity with single upper and lower heating elements. The upper heating element is usually used for broiling while the lower is for baking. The electric oven now found in many modern kitchens, which is of the stove oven type, does not permit simultaneous cooking of different food items at varying temperatures. This makes preparation of meals requiring multiple oven cooked goods very time consuming as well as cost inefficient. Therefore there is a need for the design of more efficient and user friendly household electric ovens by incorporating an improved energy conservation mechanism and flexible compartmentalization.
Many attempts have been made to minimize the cost and cooking time of the oven by small improvements. U.S. Pat. No. 2,848,592 discloses an electric oven with angularly adjustable heating units which are intended to shorten cooking time duration and improve quality of cooked item. Two individually controlled heating elements can be placed in the oven's interior in either of the following arrangements: on the upper and lower parts of the oven, the right and left walls of the oven, or at the upper right corner and lower left corner of the oven or vice versa.
Another patent, WO Pat. No. 2,013,082,890, discloses an electric oven having its external shell coated with a thermal insulating silicate surface coating. Another feature of this oven is a door consisting of two or more glass layers with mirrors making up the innermost layers to reflect heat towards the oven cavity's central region. The main objective of this invention is to address thermal inefficiency of widely existing electric ovens.
European Pat. No. 1,785,673 discloses a double compartment oven with two doors utilizing a lateral insulated separation wall that is detachable. The oven disclosed in this patent has a separate heat and time control for each compartment and a single heat and time control for the whole oven space, that is in the absence of the separation wall, thereby increasing overall efficiency relative to a traditional one cavity oven.
Canadian Pat. No. 2552825 discloses an electric oven comprising an oven body divided by a tray into upper and lower sections, with each compartment having its own convection system. This invention allows for simultaneous cooking of two different food items at different temperatures and baking of small food portions while reducing energy consumption relative to a conventional oven.
While these references may be adequate for their intended purpose, there is still a need for increased flexibility in terms of volume of oven cooking space and number of oven compartments. A common complaint with respect to ovens that incorporate an insulated horizontal divider allowing for compartmentalized cooking is that the size restriction of the cooking spaces formed places restrictions on what can be safely cooked. Also, the incorporation of a horizontal insulated divider in a typical electric oven prevents the use of the bake function in the top cavity formed by the divider. The only heating element available for this compartment is the broil element, which is often not practical. The flexibility to customize oven cooking space has also not been fully addressed.
While purchasing multiple ovens is an option, it is extremely costly and requires a large amount of space. Therefore, there is a need for an electric oven comprising of compartments with independently controlled temperatures, and separated by removable insulated vertical and horizontal partitions.
SUMMARY
This novel idea allows for the compartmentalization of an oven into various configurations based on the placement of interchangeable insulating partitions. This is made possible by the use of multiple heating elements on the surfaces of the oven interior which provide heat. The oven can be divided vertically and horizontally, with the use of insulated dividers. In traditional ovens, or those which incorporate only a single horizontal divider, this vertical division is not possible due to the use of a single heating element (either baking or broiling) which spans the entire length of the heating surface. The horizontally placed divider would be best utilized for trays that are long and wide. Alternatively, the divider can be placed vertically to fit items that would be too tall to fit in a horizontal compartment, such as a large turkey. The heating elements incorporated on the surfaces of the oven interior would be individually controlled by the user, allowing the user to vary the temperature in any combination of oven divisions. The temperature in each compartment would not be affected by the temperature of the adjacent compartments due to the thermal insulation of the divider, and this temperature would be monitored by a feedback control loop involving a temperature sensor, pickup coil, and heating element.
The divider used in conjunction with this invention would be required to be made up of two outer layers encompassing an interior layer. The outer layers would be composed of a layer of stainless steel or similar material of high heat tolerance, while the middle layer would be made of a thicker high temperature insulating material. The outer layer is made of stainless steel for easy cleaning and the middle layer consists of high quality insulation to prevent heat transfer between the various = compartments. The dividers would also contain grooves similar to those found on the interior surfaces of the oven cavity to allow for the placement of oven racks or additional dividers to allow for further oven compartmentalization.
Additional features and advantages of the present invention will become more apparent from the detailed description that follows, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION
The following descriptions of the illustrative embodiments of the invention are described in the context of an electric oven. These embodiments are not intended to be limited to the electric oven.
Rather, they are intended to apply to any form of oven that uses a standard heating element and/or broil element to provide heat to one or more independent cavities. For example, a toaster oven may incorporate the same features that are embodied by these figures.
The electric oven depicted in FIG. 1 embodies a previous invention which contains a single oven divider 1 in the horizontal position. This divider slides into the slots 2 for the cooking racks for the oven.
It should be noted that this invention embodies an oven cavity with the capability of splitting into independent compartments 3 and 4 and the partition that allows this division to take place. The remaining features of this oven resemble those of a conventional electric oven: a single bottom heating element 5, a broiling element on the upper surface of the oven cavity (not shown), and a single fan for convection cooking 6. It is important to note that the slots meant for the cooking racks only allow for the incorporation of the divider in the horizontal position.
FIG. 2 depicts the proposed oven, with the partition 7 in the same horizontal position as the one shown in FIG. 1. A notable change to the design of the conventional oven described previously is the presence of two lower heating elements 8 and 9 that work independently of one another. These elements can be controlled separately by stovetop controls (not shown). One element can be turned off while the other provides heat to the entire oven interior or to a single partitioned compartment or both can be turned on and providing heat at the same or at different temperatures.
Both heating elements are heated by the passing of an electric current through the pickup coils 16, 17,20, 21 (shown in FIG. 4 and FIG. 5) residing in the pickup coil compartments 18,23. Each heating element is heated by electric current flowing from one of said pick-up coils. Two broiling elements 14, 15 (shown in FIG. 4) secured to the upper surface of the oven cavity are also present, with a pick-up coil providing the electric current for each.
It should also be noted that the combination of elements used in the embodied invention is arbitrary.
For simplicity the element layout from a typical electric oven is used, with regular heating elements on the bottom surface and broiling elements on the upper surface.
FIG. 3 illustrates the proposed oven with the partition in the vertical position, dividing the oven cavity into two vertical sections (10, 11). In order for the divider to be oriented in this manner, the two slots on the top (13) and bottom (22) of the oven cavity secure it in place.
Again, the two lower heating elements ere shown, and the two broiling elements on the upper surface exist in the same orientation.
FIG. 3 also depicts a grooved partition (12), allowing for the attachment of a cooking rack or another horizontal partition for further division. A similar groove (not shown) exists on the other side of the divider also for the purpose of attaching a cooking rack or an additional divider.
In FIG. 4 and FIG. 5, an exploded view of the upper and lower surfaces, respectively, is presented.
This view shows multiple aspects of the embodied invention, including the upper and lower slots for orienting the oven partition in the vertical position (13 and 22). These slots span the depth of the oven cavity, leaving some space on either side. Also present in these figures are the two heating elements (8, 9) on the lower surface and the two broiling elements on the upper surface (14, 15). Each element on both the upper and lower surface is fed electric current by one pick-up coil (16, 17, 20, 21). Two individual pick-up coils, each providing electric current to one element, reside inside one coil compartment located on each of the upper and lower surfaces of the oven cavity (18, 23). FIG. 4 depicts 4 small lights (19) on the upper surface of the oven cavity. In the illustration, one light is positioned in each corner of the surface, such that if the partition is placed in the vertical orientation, each of the two cavities would be illuminated by one light at the front of the oven and one at the rear. It should be noted that the number of lights used and their respective positions is arbitrary and is shown in this particular orientation for simplicity.
Finally, FIG. 6 shows one possible orientation of the oven compartments using multiple dividers. The second, smaller divider (24) takes advantage of the groove (12) located on the larger divider and the grooves present on the interior surface of the oven cavity. It should be noted that while this is one possible orientation attainable by the user of the oven, a multitude of combinations not limited to those seen in the previous figures are attainable.1. A conventional oven whose interior surfaces are comprised of multiple heating elements allowing for the compartmentalization of a plurality of independent heating zones, each containing its own:
= resistance coil configured such that an electrical current travelling through said coil generates heat;
= a means of sensing the temperature of each compartment and relaying the signal to said resistance coil;
= feedback control loop consisting of said temperature sensing gauge, a heating element, and a controller.
2. A conventional oven as claimed in claim 1, wherein control of each heating element is achieved by a user operated control panel located on an outer surface of said oven.
3. An oven as claimed in claim 1 consisting of insulated dividers that fit into grooves of any interior surface and into grooves of other dividers.
