Description

FIELD OF THE INVENTION

Embodiments of the present invention relate to food cooking appliances.

BACKGROUND OF THE INVENTION

Outdoor cooking has become very popular, and accordingly the need for portable appliances to facilitate outdoor cooking has increased. As part of this trend, a desire has developed to practice all forms of cooking outdoors, including baking. A number of different appliances are currently available to bake food, particularly pizza, outdoors. In order to bake or cook pizza, the baking chamber is preferably very hot and traditionally the best pizza ovens have been constructed of brick which enables the baking chamber to be maintained at very high temperatures. Cooking temperatures above 400 F degrees are normally required, and preferable cooking temperatures may range as high as 700 F-900 F degrees or even higher. Furthermore, it is preferable to cook pizza on a stone or stone-like surface because the stone efficiently conducts and holds heat, which may keep the oven temperature steady even when a cold ingredient (such as an uncooked pizza) is introduced. A stone cooking surface not only helps the pizza cook more evenly, but also allows the bottom to get crisp. A crisp outer crust is considered essential for a quality pizza.

Cooking appliances require some form of power and/or fuel to generate the heat required for cooking. With respect to outdoor ovens in particular, it may be difficult to provide sufficient power to generate the high temperatures desired to cook pizza. Power may also be needed to rotate a pizza stone relative to a heat source when using a compact portable outdoor oven to cook pizza. However, in order to be truly portable, an oven should not rely solely on alternating current (AC) as a power source. Conversely, the power requirement of traditional gas heating elements capable of generating the desired temperatures for cooking pizza may require relatively large supplies of gas fuel, e.g., twenty-pound propane cylinders. Further, non-electric heating elements, such as conventional propane burners, may be prone to uneven heating and poor reheating characteristics when tasked with heating a series of cold items, one after the other. As a result of these challenges, manufacturers have struggled to provide an affordable and truly portable oven for cooking pizza that is able to generate and maintain the desired cooking temperatures. Manufacturers have also found it difficult to provide an affordable and compact portable oven for cooking pizza that distributes heat in a manner that produces a crisp outer crust without burning portions of the pizza.

In light of the foregoing challenges, there is a need for an affordable portable pizza oven that is untethered to a continuous supply of AC electrical power. Portable ovens including an onboard replaceable or rechargeable battery pack are needed to provide nearly unlimited portability.

There is a need also for a portable pizza oven that is relatively light, compact, and capable of being used safely on a table top surface. In particular, there is a need for a compact oven that is still capable of cooking a pizza approximately sixteen (16) inches in diameter to provide sufficient amounts of food for several people at a time.

There is a need also for a portable pizza oven that is able to generate and sustain the high temperatures required for cooking pizza. A preferred oven should be able to maintain required cooking temperatures while cooking a series of pizzas. As such, a preferred portable pizza oven should be capable of more quickly rebounding to a desired cooking temperature when tasked with heating a series of cold items, one after the other. As a result of maintenance of high temperatures, cooking times preferably may be under ten (10) minutes, more preferably under seven (7) minutes, and even more preferably about five (5) minutes.

There is a need also for a portable pizza oven that improves the ease with which a pizza may be quickly and evenly cooked to have a crisp outer crust without burning. In particular, there is a need for an oven that applies heat in a manner that crisps all portions of the crust evenly, including the very center of the pizza and the outer edge.

There is a need also for a portable pizza oven that is esthetically pleasing and mimics the look and feel of a traditional brick oven. In particular, because pizza ovens must be maintained at such a high temperature, there is a need for an oven that can quickly acquire cooking temperature and maintain it without requiring the user to open and close a baking chamber door which would necessarily be very hot to the touch.

There is a need also for a portable pizza oven that is designed to be used safely outdoors without generating excessively high outer surface temperatures.

There is a need also for a portable pizza oven that efficiently manages the collection of grease or other food particles that fall from the pizza during cooking or during the process of placing the pizza in, and removing the pizza from, the oven. Still further, there is a need for a portable pizza oven that is easily cleaned after use.

The infrared burner 190 emitter may be disposed within the housing lower portion 100 below the opening 119 provided in the heat shield 117 such that the opening 119 registers with trapezoidal openings 167 provided in the metal pan 166 as it rotates to allow the infrared heat to be directly applied to the baking stone 140. The number and size of the pan openings 167 may be such that when the metal pan 166 is rotated at a constant speed, the infrared burner 190 emitter disposed below the metal pan is exposed to the baking stone 140 supported by the metal pan more than half of the time that the motor 160 is rotating the metal pan.

The baking stone 140 may be disposed generally centrally between the rear wall 108, the lower front lip 122, the right side wall 126, and the left side wall 128 of the oven 10. The baking stone 140 may be provided in the open space above the removable tray or heat shield 117. Preferably the baking stone 140 may have a diameter of about 16 inches. Preferably the baking chamber volume (i.e., the space between the heat shield 117, the baking chamber opening 118, and an inner liner) is sufficient to permit items having a greater vertical dimension than that of a pizza to be cooked within it. The heat shield 117 may include an upper peripheral lip extending upward and away from a central surface of the heat shield that assists in the efficient collection of food droppings on an upper surface of the heat shield and which may be removed for cleaning.

The oven 10 may further include an inner back wall 200, providing some heat shielding function interposed between the back burner 144 and the rear wall 108. Further, one or more portions of the housing upper portion 101 may include an inner liner 115 that provides some heat shielding function for the outer surface of the oven 10. A shiny gently curved heat reflector 145 may disposed within the baking chamber between the curved back burner 144 and the baking stone 140.

The infrared burner 190 and the back burner 144 may be connected to a common gas manifold 148, which in turn may be connected to a single unit, dual gas valve/regulator 146. Both burners 144 and 190 may operate off of one valve 146 with dual outlets for convenience and reduction of manufacturing cost. The control knob 120 may be used to control the dual gas valve/regulator 146. The fuel connection hose 150 may connect to the dual gas valve/regulator 146. An ignitor 121 for the back burner 144 and the one or more infrared burners 190 may be disposed on the front face 110 of the housing lower portion 100. The combined output of the back burner 144 and the infrared burner 190 may be between 18,000 to 25,000 BTU/hour, and more preferably between 20,000 to 24,000 BTU/hour. A back burner 144 output in the range of 10,000 to 13,000 BTU/hour and an infrared burner 190 output of in the range of 8,000 to 11,000 BTU/hour is preferred. Both burners may share a common low pressure dual gas valve/regulator 146 (i.e., a regulator operating at or about ½ PSI) as compared to a high pressure regulator that provides from 1 PSI to 10 PSI. The low pressure regulator 146 may enable the portable oven 10 to operate for a sustained period (up to or exceeding 60 minutes) using a one-pound (1 lb) propane gas cylinder. The infrared burner 190 preferably may radiate heat directly upward towards the baking stone 140. The back burner 144 preferably has gas openings on the top, more preferably on the top side closer in proximity to the baking stone 140 than to the rear wall 108. The infrared burner 190, in conjunction with the rotating baking stone 140, may heat the bottom of the baking stone evenly while the back burner 144 heats the upper part of the baking chamber to cook the top of a pizza at the same time.

The oven may further include a DC battery or battery system contained within the housing lower portion 100 used to power the rotary motor 160. It is appreciated that the battery system could be located anywhere within the oven 10, or even located outside of the oven without departing from the intended scope of the invention. An AC connection 170 to the DC battery system may be provided in some embodiments to permit recharging of the battery system.

As will be understood by those skilled in the art, the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The elements described above are provided as illustrative examples for implementing the invention. One skilled in the art will recognize that many other implementations are possible without departing from the present invention as recited in the claims. For example, the shapes and sizes of various elements of the embodiments of the invention may be changed without departing from the intended scope of the invention. Accordingly, the disclosure of the present invention is intended to be illustrative, but not limiting, of the scope of the invention.
