Description

Oven equipment with combined radiant grilling and convection grilling Technical field

The subject matter generally relates to oven appliances, and more specifically to oven appliances with combined convection heating features and radiant heating features.

Background technique

Conventional household and commercial oven appliances generally include a cabinet that defines a cooking chamber for receiving food for cooking. The heating element is positioned in the cooking chamber to provide heat to the food located therein. The heating element may include, for example, a roasting heating assembly positioned at the bottom of the cooking chamber and/or a broiler heating assembly positioned at the top of the cooking chamber. A typical broiler heating assembly includes one or the other of a radiant heating element or a convection heating element, but not both.

Some conventional devices include a broiler assembly that uses burners or electric heating elements directed toward a predetermined heating surface. During use, the burner or electric heating element heats the predetermined heating surface to an elevated temperature, so that heat can be radiated above the food being cooked, for example. In other words, in these conventional broiler elements, radiation is used as the only heat transfer method. Generally, these conventional devices cannot provide uniform or desired heat distribution over the food being cooked. For example, the broiler element may not uniformly heat the predetermined heating surface. In turn, the radiation from the predetermined heating surface may heat or cook the item in an undesirable or uneven manner.

Other conventional equipment only provides gas burners for roasting. Such equipment cannot quickly transition from baking to roasting, and vice versa. For example, at a given time, only one gas burner can be ignited because simultaneous burner operation may cause poor combustion. In such a system, the transition between roasting and roasting may require significant time, because one burner (for example, roasting burner) needs to be turned off and then another burner (for example, roasting burner) needs to be ignited .

In addition, in conventional equipment, the grilling element may require a significant amount of preheating time before reaching the appropriate broiler temperature. This extra pre-heating time may frustrate the user and/or hinder the cooking operation.

Therefore, an oven device with an improved broiler assembly is desired. Specifically, it is desirable to have an oven apparatus that can provide a broiler assembly that can provide uniform heat distribution over a part of the cooking chamber. In addition, what may be desired is a broiler assembly for quickly reaching the indicated temperature.

The convection heating element is disposed outside the cooking chamber and is in convective communication with the cooking chamber to supply heated gas to the cooking chamber. The radiant heating element is arranged in the cooking chamber near the top wall of the cooking chamber.

In another aspect of the present disclosure, an oven device is provided. The oven device includes a cabinet that defines a cooking chamber to receive items to be cooked. The cooking chamber includes a top wall, a bottom wall, a rear wall and opposite side walls. The top wall and the bottom wall are spaced apart in the vertical direction. The opposing side walls are spaced apart along the lateral direction. The convection duct extends along a part of the cooking chamber to guide the heated gas therethrough.

Each example is provided to explain the present invention, not to limit the present invention. In fact, it is obvious to those skilled in the art that various modifications and changes can be made in the present invention without departing from the scope or spirit of the present invention. For example, features shown or described as part of one embodiment can be used with another embodiment to yield a still further embodiment.

When used in the content of an angle or direction, these terms are included within ten degrees greater than or less than the angle or direction. For example, "substantially vertical" includes directions within ten degrees of vertical in any direction (for example, clockwise or counterclockwise). The terms "upstream" and "downstream" refer to the relative direction of fluid flow in a fluid path. For example, "upstream" refers to the direction in which fluid flows, and "downstream" refers to the direction in which fluid flows.

Turning now to the drawings, Figures 1 to 3 provide several views of an exemplary oven apparatus that can incorporate embodiments of the subject matter. For example, FIG. 1 provides a perspective view of an oven apparatus 10 according to an exemplary embodiment of the present subject matter. Figure 2 provides a cross-sectional view of the oven device 10 taken along line 2-2 of Figure 1. Figure 3 provides an enlarged cross-sectional view of the heating element of the exemplary oven apparatus of Figure 2. The oven device 10 defines a vertical direction V, a lateral direction L, and a lateral direction T. The vertical direction V, the lateral direction L and the lateral direction T are perpendicular to each other and form an orthogonal direction system. As will be understood, the oven apparatus 10 is provided as an example only, and the subject matter can be used in any suitable oven apparatus. For example, the oven device may be a wall oven or a free-standing stove that also includes a stove top, as shown in the figure. As another example, the oven apparatus may include a plurality of internal cavities defining a plurality of heating chambers in the oven apparatus. Therefore, the subject matter can be used with other oven or stove appliance configurations, for example, defining multiple internal cavities for receiving food and/or an oven or stove appliance configuration having a different configuration than that shown in FIG. 2.

The oven device 10 includes an insulated cabinet 12 having an internal cooking chamber 14 defined by an inner surface 15 of the cabinet 12. The cooking chamber 14 is configured to receive one or more foods to be cooked. The oven apparatus 10 includes a door 16 rotatably mounted to the cabinet 12, for example, by a hinge (not shown). The handle 18 is mounted to the door 16 and helps the user to open and close the door 16 in order to access the opening 20 of the cooking chamber 14. For example, the user can pull the handle 18 to open or close the door 16 and access the cooking chamber 14 through the opening 20.

The oven device 10 may include one or more seals or gaskets (not shown) between the door 16 and the cabinet 12, which help when the door 16 is closed as shown in FIG. The heat and cooking fumes are kept in the cooking chamber 14. A plurality of parallel glass panes 22 are provided for viewing the contents of the cooking chamber 14 when the door 16 is closed, and to help insulate the cooking chamber 14. The baking support 24 is positioned in the cooking chamber 14 for receiving food or a container containing the food. The baking support 24 is slidably received on the raised rib 26 or the sliding track, so that when the door 16 is opened, the support 24 can be easily moved into and out of the cooking chamber 14.

As shown, a plurality of walls define the cooking chamber 14. For example, the cooking chamber 14 includes a top wall 30 and a bottom wall 32, which are spaced apart along the vertical direction V. The left side wall 34 and the right side wall 36 (as defined according to the front view shown in FIG. 1, for example, viewed from the perspective of a user facing the oven device 10 to approach/use the oven device 10 and/or the cooking chamber 14) The top wall 30 and the bottom wall 32 extend between and are spaced apart along the lateral direction L. The rear wall 38 additionally extends between the top wall 30 and the bottom wall 32, and also extends between the left side wall 34 and the right side wall 36, and the rear wall is spaced apart from the door 16 along the transverse direction T. Therefore, the cooking chamber 14 is defined between the top wall 30, the bottom wall 32, the left side wall 34, the right side wall 36, and the rear wall 38.

Optionally, the lower heating assembly 42 may be included in the oven device 10, for example, for performing baking operations in the cooking chamber 42. The lower heating assembly 42 may include a separate heating element (not shown) disposed in the cooking chamber 14, for example, adjacent to the bottom wall 32. In some embodiments, the lower heating assembly 42 includes a gas burner. In some such embodiments, additional components such as igniters and fuel lines may be provided. Alternatively, the lower heating assembly 42 may include an electric heating element, or may be any other suitable baking assembly with any other suitable heating element.

As discussed in detail herein, an upper heating assembly (eg, broiler assembly 44) may be included in the oven apparatus 10. The broiler assembly 44 includes a convection heating element 50 and a radiant heating element 52. The radiant heating element 52 may be an electric heating element, such as a resistance heating rod shown in FIG. 2. The convection components of the broiler assembly 44 include one or more air handlers 46, 48 (for example, fans or blowers) and a convection heating element 50. As shown, the convection heating element 50 is generally positioned away from the cooking chamber 14 so that convective heat (rather than radiant heat) is received from the convection heating element 50 into the cooking chamber 14. The convective heating element 50 may be an electric heating element, such as a resistance heating rod, or a gas burner configured to generate heated gas for cooking operations. One or more air handlers 46, 48 may be in fluid communication with the convection heating element 50 to urge the heated gas from the convection heating element 50 into the cooking chamber 14 through the broiling outlet 132. As will be described in detail below, the broiling outlet 132 may be provided at or near the top part of the cooking chamber 14, for example at the top wall 30, such as at the intersection of the top wall 30 and the rear wall 38 Or close to the intersection. In addition, during certain operations, the broiling outlet 132 may be downstream of one or more air handlers 46, 48 and convection heating element 50 to receive heated gas therefrom.

Advantageously, the heating elements 50 and 52 can use different heat sources, for example, the convection heating element 50 can be a gas burner, and the radiant heating element 52 can be an electric heating element, so that the combined system (for example, the broiler assembly 44) provides It has an advantage over a broiler that uses a single energy source (such as electric only or combustion only). In such an embodiment, the radiant heating element 52 may be a low power heating element. For example, although a typical heating element in an all-electric oven device may use about 3000 watts to about 4000 watts, the radiant heating element 52 may only use about 1400 watts or about 1500 watts. Therefore, the combined broiler assembly 44 can provide improved heat intensity compared to a purely radiant or purely convective broiler system. By bathing the electrical element 52 in the hot air or exhaust from the convection heating element 50, a relatively low power (for example, about 1500W) electrical element 52 can be achieved allowing the electrical element to radiate a large amount of energy to the cooking chamber The temperature on the food in the medium, and together with the convective heating element 52, give superior grilling results.

The oven apparatus 10 may further include a controller 40, which is configured to control one or more operations of the oven apparatus 10, for example. For example, the controller 40 may control at least one operation of the oven device 10 including the broiler assembly 44. The controller 40 may communicate (via, for example, a suitable wired or wireless connection) with the heating elements 50 and 52 and other suitable components of the oven apparatus 10, as discussed herein. Generally, the controller 40 may be operable to configure the oven device 10 (and its various components) for cooking. Such a configuration may for example be based on multiple cooking factors of the selected operating cycle or mode.

As an example, the controller 40 may include one or more memory devices and one or more microprocessors, such as general-purpose or special-purpose microprocessors operable to execute micro-control codes or programming instructions related to operating cycles. The memory may represent random access memory, such as DRAM, or read-only memory, such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in the memory. The memory may be a separate component from the processor, or may be included in the processor.

The controller 40 may be positioned at various positions of the entire oven device 10. In the illustrated embodiment, the controller 40 may be located in the user interface panel 62 of the oven device 10, as shown in FIGS. 1 and 3. In some of these embodiments, the input/output ("I/O") signal may be in the controller 40 of the oven device 10 and various operating components (such as convection heating element 50, radiant heating element 52, one or more The air handlers 46, 48, controls 64, display components 66, sensors, alarms, and/or other components that may be provided are routed. For example, the signals may be routed along one or more wiring harnesses. The wiring harness can be led out through the casing 12. In some embodiments, the controller 40 communicates with the user interface panel 62 and the control member 64, and the user can select various operating features and modes through the user interface panel and the control member, and monitor the oven The process of the device 10. In one embodiment, the user interface panel 62 may represent a general purpose I/O ("GPIO") device or function block. In one embodiment, the user interface panel 62 may include input components, such as various electrical One or more of mechanical or electromechanical input devices (including rotary dials, buttons, and touch pads). The user interface panel 62 may include a display component 66, such as a digital or analog display configured to provide operating feedback to the user .

As mentioned above, certain embodiments of the convection heating element 50 are provided as gas burners. In some such embodiments, the convective heating element 50 includes a burner tube 68. The burner tube 68 is generally located away from the grilling outlet 132 so that the flame output by the burner tube 68 is isolated and separated from the grilling outlet 132, for example, to prevent the flame from contacting the grilling outlet 132 or otherwise entering the cooking chamber 14. A fuel line (not shown) may be connected in fluid communication with the combustor tube 68 to selectively direct fuel (eg, natural gas) to the combustor tube 68. One or more igniters (not shown) may be provided adjacent to the burner tube 68 for igniting the fuel. During operation, after receiving fuel at the burner tube 68, a flame may therefore be generated at the burner tube 68.

In some embodiments, the burner housing 72 contains at least a portion of the convection heating element 50. For example, the combustor housing 72 may include a plurality of outer walls 74, 76 that house the combustor tube 68. The outer walls 74, 76 may be substantially solid, impermeable members to partially isolate the burner tube 68. During use, the flame generated at the burner tube 68 is at least partially contained by the burner housing 72, for example, separated from the broiling outlet 132. Specifically, the flame is at least partially surrounded by outer walls 74,76. The inlet 78 is defined as passing through one or more of the outer walls (eg, 76), while one or both of the outer walls 74, 76 define a separate outlet 80. For example, the outer walls 74, 76 may collectively define an outlet 80 directly above the burner tube 68. The inlet 78 may generally allow air to enter the combustor housing 72, while the outlet 80 directs flame exhaust out of the combustor housing 72, for example as a heated gas.

As best seen in FIG. 3, the combustor housing 72 may include a plurality of inner walls 82, 84, such as a first inner wall 82 and a second inner wall 84 disposed oppositely. The inner walls 82, 84 may be spaced apart in the transverse direction T, for example. In addition, the inner walls 82, 84 may be bounded within the combustor housing 72 by the outer walls 74, 76. Optionally, the inner walls 82, 84 may form a flame shield disposed above the burner tube 68. During use, the flame generated at the burner tube 68 may extend into the flame hood formed by the inner walls 82, 84 and be contained therein. In turn, the inner walls 82, 84 may at least partially isolate the flame from the outer walls 74, 76, for example, so that the flame does not contact the inner walls 82, 84.

The exhaust path 86 may be defined between the inner walls 82 and 84 that are disposed oppositely. For example, the exhaust path 86 may extend between the combustor tube 68 and the outlet 80 of the combustor housing 72. In some such embodiments, the inner walls 82, 84 are spaced apart from the outer walls 74, 76 in the transverse direction T, for example. One or more air chambers 88, 90 may be defined between the inner walls 82, 84 and outer walls 74, 76 of the combustor housing 72. An air chamber 88 may extend between the first inner wall 82 and the outer wall 74 of the burner housing 72 in the transverse direction T toward the cooking chamber 14. The other air chamber 90 may extend away from the cooking chamber 14 in the transverse direction T between the second inner wall 84 and the other outer wall 76 of the burner housing 72.

In some embodiments, the inlet 78 includes a plurality of openings 92, 94 that extend through the outer wall 76 of the combustor housing 72 in the transverse direction T, for example. Optionally, multiple discrete groups of openings can be provided. For example, the first set of openings 92 may extend through the outer wall 76 of the combustor housing 72. As shown, the first opening 92 may extend through the outer wall 76 under the inner walls 82, 84, for example in the vertical direction V. In some such embodiments, the first opening 92 is defined below the combustor tube 68. Each of the first openings 92 may be substantially parallel. Additionally or alternatively, each of the first openings 92 may be defined along a certain sequence such that the first openings 92 are arranged side by side in the lateral direction L.

The second set of openings 94 may further extend through the outer wall 76 of the combustor housing 72. As shown, the second opening 94 may extend through the outer wall 76 above the combustor tube 68, for example in the vertical direction V. In some such embodiments, the second opening 94 extends into the air chamber 88, 90. Each second opening 94 may be substantially parallel. Additionally or alternatively, each of the second openings 94 may be defined along a certain sequence such that the first openings 92 are arranged side by side in the lateral direction L.

Optionally, one or more ports 96 may be defined to be in fluid communication with the inlet 78. As shown, the port 96 may extend from the air chambers 88, 90 to the outlet 80. In addition, the port 96 may be defined above the second opening 94, for example, near the outlet 80. For example, the port 96 may be defined as an angled top portion through the inner wall 82,84. During operation, air may be directed through the air chambers 88, 90 (eg, from the second opening 94) and out of the port 96.

In some embodiments, an isolated air supply duct 110 is provided. As shown, the air supply duct 110 defines a passage 112 extending between the two ends 114,116. When assembled, the passage 112 may be in fluid communication with the combustor housing 72. The inlet 118 of the air supply duct 110 may be defined at one end 114 and the outlet 120 may be defined at the opposite end 116. Optionally, the air supply duct 110 may be partially or completely contained in the cabinet 12. In some such embodiments, the inlet 118 is defined to communicate with the outside environment, for example, at the bottom portion of the cabinet 12. The outlet 120 of the air supply duct 110 may be defined as an inlet 78 adjacent to the combustor housing 72, for example, directly engaged with the combustor housing 72. The air used for combustion can therefore enter the air supply duct 110 at the inlet 118 before passing through the passage 112 to the outlet 120. The air passing through the outlet 120 may then enter the combustor housing 72 at the inlet 78, for example, through the first opening(s) 92 and/or the second opening(s) 94.

In some embodiments, one or more combustion air handlers 48 (such as burner fans) are provided upstream of the convection heating element 50, for example, upstream of the gas burner. Specifically, the combustion air handler 48 may be in fluid communication with the inlet 78 of the combustor housing 72. The isolated air supply duct 110 may be provided in fluid communication between the air handler 48 and the inlet 78 of the convection heating element 50. Optionally, the combustion air processor 48 may be disposed in the channel 112 of the air supply pipe 110. During operation, the combustion air processor 48 may actuate air into the inlet 78, for example, to promote combustion within the combustor housing 72 and/or to force heat to escape from the combustor housing 72.

In some embodiments, the convection duct 130 is provided in fluid communication with the cooking chamber 14. The convection duct 130 may extend along a part of the cooking chamber 14 (for example, outside the cooking chamber 14) to guide the heated gas therethrough. For example, the convection duct 130 may extend from the convection heating element 50 to the broiling outlet 132. The convection duct 130 can thus provide fluid communication between the heating element 50 and the cooking chamber 14. In some such embodiments, the broil outlet 132 is located at the top wall 30 of the cooking chamber 14 near the outlet 80 of the burner housing 72. The broiling outlet 132 may be defined to be perpendicular to the transverse direction T, for example.

In other embodiments, an optional channel (eg, circulation channel 134) may be defined by the convection duct 130. Specifically, the circulation channel 134 may be defined to be in fluid communication between the bottom part of the cooking chamber 14 and the top part of the cooking chamber 14. In some embodiments, the circulation channel 134 extends perpendicular to the transverse direction T, for example, along the vertical direction V. At least a portion of the circulation passage 134 may be defined by the rear wall 38, for example, between the outer wall 74 and the rear wall 38 of the combustor housing 72. In other embodiments, a bottom heating element may be included at or near the bottom portion of the cooking chamber 14 to provide heat to the bottom portion of the cooking chamber 14 without the optional circulation channel 134.

One or more convection air handlers 46, such as circulation fans, are provided in fluid communication with the convection duct 130. Through the convection duct 130, the convection air handler 46 may be in fluid communication with the outlet 80 of the combustor housing 72. The convection air handler 46 may be operated to direct the heated gas through the convection duct 130 according to one or more operations. During certain operations, air may be recirculated from one part of the cooking chamber 14 to another. For example, the convection air handler 46 can urge air through the broiler channel 132 and to or from the broiler outlet, as will be described below. In some embodiments, the convection air handler 46 is disposed in the convection duct 130, for example, installed at the circulation channel 134. In addition, the convection air handler 46 may be positioned along the vertical direction V below the convection heating element 50.

As shown in FIG. 4, the oven apparatus 10 is operable to urge heated gas to enter the cooking chamber 14, for example, to heat or cook food products positioned below the broiler assembly 44. One or more modes can be provided, such as a broiler mode. The controller 40 (FIG. 1) may activate the broiler mode in response to one or more user inputs, such as user input provided through the control 64 (FIG. 1).

The initial air flow (indicated by arrow 142) may be provided to the convective heating element 50. For example, the initial air volume may be actuated by the air handler 48 through the inlet 78 into the combustor housing 72. The initial air flow 142 may be provided from the outside environment, for example, through the inlet 118 of the air supply duct 110 (FIG. 2). The air in the combustor housing 72 may then be mixed with the fuel supplied through the combustor tube 68.

The mixture of initial air flow 142 and fuel may be ignited to produce flame exhaust (indicated by arrow 144). The combustion and back pressure generated at the combustion air handler 48 can urge the exhaust gas 144 to enter the convection duct 130 through the outlet 80 as heated gas (indicated by the arrow 146). Optionally, additional air, such as air provided through the second opening 94 (FIG. 3 ), may be mixed with the exhaust gas 144 (eg, at the outlet 80) to further form the heated gas 146. Additionally or alternatively, the air from the cooking chamber 14 may be recirculated, for example, by an air handler 46, and mixed with the exhaust gas 144 in the convection duct 130 to further form a heated gas 146.

The heated gas 146 may flow to the top of the convection duct 130 by convection, and flow from the convection duct 130 into the cooking chamber 14 via the broiling outlet 132 (FIG. 2 ). For example, in some embodiments, the exhaust gas 144 and/or the heated gas 146 may be specifically directed to the broiling outlet 132, for example, as a convective heat source for the top portion of the cooking chamber 14. After leaving the convection duct 130 at the broiler outlet 132, the heated gas 146 can flow along the top wall 30 and can flow downward from the top wall 30, for example, above and around the radiant heating element 52. Therefore, the heated gas 146 may surround the electric heating element 52 on all sides (eg, flow around the electric heating element 52) so that the electric heating element 52 is immersed in the heated gas 146. Advantageously, the heated gas 146 can be used as a convective heat source to directly heat any items positioned below the broiler assembly 44, such as food. In addition, heat can be immediately received from the heated gas 146. In addition, the radiant heating element 52 can provide radiant heat to the items under the broiler assembly 44. In this way, during the broiling operation of the oven apparatus 10, the broiler assembly 44 can advantageously provide radiant heat and convective heat to the items. For example, when the radiant heating element is immersed in the heated gas 146 as described, the preheating time of the radiant heating element 52 can be reduced.

Such a combined broiler assembly 44, for example, including a convection heating element 50 and a radiant heating element 52, can provide several advantages. For example, the broiler assembly 44 may allow control of where the hot gas flows to, thereby improving temperature distribution. As another example, the broiler assembly 44 may require a relatively short heating time. Also as an example, for example, due to the relatively small size of the low-power radiant heating element 52, the broiler assembly 44 may have a clean low-profile appearance and may be flush or nearly flush with the top wall 30 (thus increasing the cooking chamber 14 Available volume). As yet another example, the broiler assembly 44 may provide a smaller opportunity for vents than a broiler system that only uses combustion. In addition, smaller vents can result in less heat loss, which positively affects efficiency.

This written description uses examples to disclose the invention, including the best mode, and allows any person skilled in the art to practice the invention, including manufacturing and using any device or system and performing any combined method. The patentable scope of the present invention is defined by the claims, and may include other examples that occur to those skilled in the art. If such other examples include structural elements that are not different from the literal language of the claims or if they include equivalent structural elements that are not substantially different from the literal language of the claims, these other examples are intended to be within the scope of the claims.
