This application relates generally to containers and more particularly, to a cover for cooking and other containers.
The drawings, when considered in connection with the following description, are presented for the purpose of facilitating an understanding of the subject matter sought to be protected.
While the present disclosure is described with reference to several illustrative embodiments, it should be clear that the present disclosure is not limited to such embodiments. Therefore, the description of the embodiments provided herein is illustrative of the present disclosure and should not limit the scope of the disclosure as claimed. In addition, while the following description references an oil fryer such as those for Onion Ring and French Fries, it will be appreciated that the disclosure may include other types of food fryers, and containers in general.
A popular method of cooking is to fry or deep fry many food items. A brief list of foods that may be deep fried include various vegetables, french fries, potato chips, chicken, pork, beef, candy bars, ice cream, etc. Many other types of food are amenable to deep frying. Deep frying generally involves immersing the food item in a high-temperature fat-based solution, such as in cooking oil (e.g., canola oil, peanut oil, vegetable oil, olive oil, liquefied shortening, etc.) until the food is cooked, though other liquids such as water or even air can be used.
While fried foods and the fryers used to cook the fired foods are popular, the temperatures found in the frying liquids are quite high, often greater than 300 degrees Fahrenheit. Thus, body parts being accidentally submerged in hot fryer oil or items (e.g., common kitchen items such as spice shakers, utensils, aerosol cans, etc.) falling into hot oil is a dangerous possibility. Apart from safety, open fryer vessels unnecessarily allow heat to escape into air requiring frequent input of energy to maintain and/or bring oil temperatures to cooking temperature. Many fryers and/or containers do not have covers because it is not convenient for a user to frequently remove and replace the fryer and/or container cover. Thus, a system that prevents energy loss and helps avoid body parts and other items from contacting or falling into oil is desirable.
As set forth in the detailed description, in accordance with various embodiments of the present disclosure systems, methods and apparatuses for making fryers safer and/or more energy efficient are provided. With reference to the figures attached hereto, methods and devices in accordance with the present invention generally comprise a cover, having a number of flaps, doors, or plates that cover a cooking chamber containing a hot liquid, which may be opened to receive a basket or that may be lowered to submerse a basket into the chamber. These flaps, doors, or plates may or may not be hinged. The cover or a part of the cover can be maintained in an open or closed position. The closed part(s) of the cover may be also locked, for example, by a locking mechanism, preventing the basket(s), body parts, or other items from unintentionally being placed in the fryer chamber, thus increasing the safety. In such embodiments, the cover also prevents the loss of heat from the oil, thus increasing the energy efficiency. Alternatively, the cover can be maintained in a closed position, though not necessarily locked, with a primary purpose of preventing the loss of heat from the oil. In such embodiments, the cover may be vented.
In addition to safety and efficiency, another advantage of the present disclosure is the easy and cost effective retrofitting of the existing kitchens and cooking apparatus. The following disclosed embodiments may be described in terms of functional components and/or various processing steps. Each functional component may include any number of parts configured to perform specified functions and achieve various results. Those skilled in art will recognize that the disclosed apparatus and/or method are not limited to food preparation and may be used for controlling access to any container.
The detailed description herein makes use of various exemplary embodiments to assist in disclosing the present invention. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be realized and that different combinations and modifications of structures, arrangements, applications, proportions, elements, materials, or components used in the practice of the present disclosure, in addition to those not specifically recited, can be varied or otherwise particularly adapted to specific environments, manufacturing specifications, design parameters or other operating requirements without departing from the scope of the present disclosure and are intended to be included in this disclosure. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation.
In accordance with an exemplary embodiment of the present disclosure, the system, methods, and devices disclosed herein discuss frying foods and the safety and efficiency considerations related thereto. The terms “cooking” and “frying” and formatives thereof may be used interchangeably herein. Other mechanisms and devices for cooking food besides frying fall within the scope of the present disclosure, such as boiling, blanching, steaming, poaching, simmering, steeping, and the like. For consistency, “frying” will be used throughout without limiting the methods of cooking for use in conjunction with embodiments of the present disclosure.
Additionally, in certain embodiments water may be used in place of cooking oil in order to boil, poach, blanch or otherwise cook certain foods. The foods are housed within the basket and cooked in the heated water in a water chamber, where the water chamber takes the place of the oil chamber. Such foods that may be cooked by this process comprise pasta products and vegetables.
Examples of heating mechanisms used in connection with maintaining and regulating the temperature of the oil in accordance with the present disclosure include, but are not limited to, various gas and electric heating elements, as well as other now known or as yet unknown heating mechanism suitable for heating oil.
According to various exemplary embodiments of the present invention, devices used herein are available in numerous sizes and/or capacities. For example, the device may be available in commercial sizes for use by restaurants and other food-frying establishments and large food manufacturers and producers that must produce hundreds, if not thousands, of pounds of fried food every day. Commercial devices may range in size depending on the desired capacity for the device. Other embodiments of the invention provide a device that is amenable to use by smaller businesses and food stands, or even in a user's home. For example, devices in accordance with the present invention may be configured to be easily “retrofit” to existing kitchen cooking devices and appliances. Those skilled in the art will appreciate that various embodiments of the present invention can comprise floor model, ventless countertop models, pressure fryer models, and home models.
Moreover, such a device for personal use may produce as little as one serving of food and may be configured to be placed on a countertop. The materials used for the various components described herein may be various heat resistant materials, such as high temperature plastics, ceramics, metals, and the like that will not be detrimentally effected by the temperature of the oil and heating elements described herein. All sizes and capacities of devices discussed are contemplated within the scope of the present invention.
Additionally, devices in accordance with the present disclosure can include any number of safety features, for example, fire suppression systems such as those using Ansul® fire suppression systems. In such embodiments, the devices can be configured with access openings so that the fire suppression systems are capable of injecting any extinguishing agent into the device and/or at the source of any fire. In some embodiments, the device may be sufficiently sealed to extinguish any outbreak of fire within the cooking chamber. In other embodiments, there may be a combination of sealing and extinguishing agents used to suppress any fires.
Devices in accordance with the present disclosure are generally readily cleanable. For example, in some embodiments the various components, such as the covers disclosed herein, are removable or hinged to facilitate ease of cleaning. For example, the cover may be rotatable on a hinge to provide access to locations that are otherwise difficult to reach and clean. In other embodiments, components such as the flaps, plates, locking mechanisms, etc. described herein may be removable to facilitate cleaning.
The baskets of the various embodiments disclosed herein may be of any shape or size (e.g., circular, square, rectangular or otherwise). This deposit may occur in any suitable way. For example, food may simply be deposited manually by an operator into the basket. Alternatively, the depositing of the food may be automated, for example via robotic/mechanical arms, conveyors and transport mechanisms which transport the food. In various embodiments, baskets in accordance with the present invention may be designed for specific food types, such as baskets with vertical basket slots for “planar” foods (e.g., hash brown patties, chicken patties, etc.). For example, for hash brown patties, it may be desirable to keep the patties upright.
As will be discussed in more detail below,
In accordance with various embodiments, the flaps 120 of covers 110 can be maintained in a closed position, an open position, or in other positions. In embodiments where the flaps 120 are maintained in a closed position, they can be locked so they can withstand significant weight/pressure placed over them. In such embodiments, the flaps 120 are locked by the locking mechanism 130 which may be selectively released by the user. For example, the locking mechanism 130 may have a trigger that must be activated (e.g., push, rotated, lifted, etc.) by the user or by a device used by the user. In various embodiments, the flaps 120 and/or locking mechanism 130 may be biased, for example, by one or more springs, motors, or other mechanisms to return the flaps 120 to a closed position upon removal of a basket 102, at which point the lock bar 138 of the locking mechanism 130 re-engages the flaps 120 to maintain them in a locked position. The release mechanism of flaps 120 may include various photo-sensors, infrared sensors, RF sensors, and the like. Alternatively, the doors may be controlled by an operator or an automated process that signals and controls when the doors should open.
The above being noted, the flaps 120 of the cover 110 may be opened to allow the cooking chamber or interior of the fryer 100 to be accessed for cooking the food. The various covers 110 described herein may further provide heat retention benefits by preventing the escape of heat within the device. As noted above, the covers 110 may also be configured with various seals to provide insulation/heat retention and pressurization capabilities, as well as other benefits such as sound dampening.
In various alternative embodiments, such as the embodiment shown in
In the embodiments of
In accordance with various embodiments, the flaps 120 of covers 110 as disclosed herein can be maintained in a closed position, an open position, or somewhere in between. In embodiments where the flaps 120 are maintained in a closed position, they can be locked to withstand significant pressure such as a downward force of a hand or a foot. In such embodiments, the flaps 120 are locked by a locking mechanism 130 which is only released when affirmatively desired by the user. For example, the locking mechanism 130 may have a trigger that must be actuated (e.g., push, rotated, lifted, etc.) by the user or by a device used by the user.
In an embodiment such as shown in
In various embodiments flaps 120 may open upwardly or downwardly with respect to the opening of the cooking chamber. In some embodiments flaps 120 may be closed even after a basket 102 is lowered into the cooking liquid and may be kept closed while the food inside the basket 102 is being cooked. In different embodiments flaps 120 may be an integral part of cover 110 or may be easily removable and/or replaceable. In such embodiments the horizontal surface of the cover 110 may be kept totally or partially covered by flaps 120, as desired.
In the embodiments shown in
In some embodiments, with reference to
In various alternative embodiments, such as the one shown in
While the locking mechanism 130 is hinged on one side in all described embodiments, it is known to those skilled in the art that a non-hinged locking mechanism may be also used in place of the locking mechanism 130. For example an electrical push-button on the surface of the face-plate 144 may activate a solenoid that in turn engages or disengages a lock bar 138 with the flaps 120 or lifting plates 520 in their open and/or closed positions.
In various embodiments such as any of those described herein, the basket(s) 102 may be raised, lowered, rotated, and/or translated by a mechanical device operated manually by a user, for example, by raising a handle which is attached to the basket or basket platform. Other mechanisms may likewise be manually operated. For example, by turning a crank the basket may be raised, and if needed, translated to a dumping position, where it engages a lip or other section of the device, proximate an exit chute, which causes the basket to rotate or pivot and allow the food to be ejected through the chute.
Additionally, as mentioned above, in various embodiments, various parameters of the present invention may be automated with one or more controllers. For example, a controller may regulate, among other aspects, the amount of time for cooking, movement of the basket(s), movement of foods from one section to another, or the like, all according to pre-programmed settings or from input from a user, for example through a key pad or various buttons, dials or switches. Controller may comprise any type of controller known in the art for controlling electrical and/or mechanical systems (e.g., printed circuit boards and the like). As a motor controller, controller may direct the operation of a motor to move/agitate and/or move the basket. In other embodiments, controller accepts input from a user for temperature, time, tilt angle, depth of travel, and other parameters a user would want to control in relation to the operation of the device. In further embodiments, controller may control automatic extraction of the food from device when the cooking process is complete.
In various embodiments and as shown in the various figures attached hereto, a plurality of baskets may be provided within device in various configurations (e.g., side-by-side, stacked, etc.). By providing multiple baskets, different foods can be kept segregated from others allowing for individual parameters relating to the processing to be controlled (e.g., keeping fish separate from French Fries). Additionally, larger total batches may facilitated.
Finally, various principles of the present invention have been described in exemplary embodiments. However, many combinations and modifications of the above-described structures, arrangements, proportions, elements, materials, and components, used in the practice of the invention, in addition to those not specifically described, can be varied without departing from those principles. Various embodiments have been described as comprising automatic processes, but these processes may be performed manually without departing from the scope of the present invention.
Changes can be made to the claimed invention in light of the above Detailed Description. While the above description details certain embodiments of the invention and describes the best mode contemplated, no matter how detailed the above appears in text, the claimed invention can be practiced in many ways. Details of the system may vary considerably in its implementation details, while still being encompassed by the claimed invention disclosed herein.
Particular terminology used when describing certain features or aspects of the invention should not be taken to imply that the terminology is being redefined herein to be restricted to any specific characteristics, features, or aspects of the invention with which that terminology is associated. In general, the terms used in the following claims should not be construed to limit the claimed invention to the specific embodiments disclosed in the specification, unless the above Detailed Description section explicitly defines such terms. Accordingly, the actual scope of the claimed invention encompasses not only the disclosed embodiments, but also all equivalent ways of practicing or implementing the claimed invention.
The above specification, examples, and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended. It is further understood that this disclosure is not limited to the disclosed embodiments, but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
While the present disclosure has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this disclosure is not limited to the disclosed embodiments, but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
