Description

Technical Field

[0001] The present invention relates to a grilling device.

Background Art

[0002] Conventionally, a grilling device mainly includes a fixed heat source that cooks food by radiant heat. In one example, the grilling device includes a substantially planar and horizontal heat source and a plurality of support attachments, each of which is at a different distance below the heat source. Food is provided to the heat source (for example, a grill pan disposed in one of the support attachments). The distance between the heat source and the food can be changed by repositioning the grill pan in another one of the support attachments. In another example, the grilling device includes a barbecue grill, and food is cooked by radiant heat, conduction (via the grill), and convection on the grill above the heat source.

[0003] Since a grilling device is used for relatively short-time, intense cooking at high temperatures (for example, grilling a steak), such a device requires constant attention from the user during cooking. It may be difficult for inexperienced users to achieve good results using such a device. The cooking speed is relatively fast and can vary depending on the type of food, the condition of the food, and the degree of cooking required. Often, grilling can lead to overcooking and burning, or insufficient cooking, posing a risk of potentially dangerous cooking. For example, barbecue is known to be a common cause of food poisoning. Since grilling foods are relatively expensive and are often used in hospitality or entertainment situations such as parties or barbecues, the "high variability" nature of grilling is unpleasant for many users.

[0004] In this specification, terms such as "front" and "forward" refer to the side of the device facing the user during normal operation, while similarly, terms such as "rear," "rearward," "behind," and "behind" refer to the opposite side that moves away from the user during normal operation. "Up" and "down" generally refer to the device during normal operation, with "down" meaning descending into the ground or floor, and "up" meaning moving away from the ground or floor.

[0005] In this specification, the term “substantially” is used to mean “exactly or practically, as understood by those skilled in the art.” This includes some variation from “exactly” for practical considerations. For example, in the art of the present invention, “substantially horizontal” may include ±10° from the horizontal. [Overview of the project]

[0006] According to a first aspect of the present invention, a grilling apparatus, the apparatus is A heat source that generates radiant heat energy that moves along a heat path during use, In the loaded state, a holder for holding food, A grilling apparatus is provided, which includes a holder mounting section for mounting a holder within a heat path when the apparatus is in a cooking state.

[0007] In some cases, the holder mounting portion is positioned to hold the holder in a predetermined position within the heat path during cooking.

[0008] In some cases, the holder defines the holding space. In some cases, when loaded, the food is placed within the holding space. In some cases, when unloaded, the holding space is empty.

[0009] In some cases, the holder is movable between an open state (food can be placed in the holding space and removed from the holding space) and a closed state (food cannot be placed in the holding space and cannot be removed from the holding space).

[0010] In some cases, the holding space has length, width, and thickness. In some cases, the length and width are greater than the thickness. In some cases, the length and width extend within the plane of the holding space. In some cases, the thickness extends perpendicular to the plane of the holding space. In some cases, in the cooked state, the plane of the holding space is substantially vertically oriented.

[0011] In some cases, the holder includes a holder surface that directs heat toward the food within the holding space.

[0012] In some cases, the holder includes a pair of holder members. In some cases, a holding space is defined between the holder members. In some cases, when loaded, both holder members are positioned in contact with the food.

In some cases, in the open position, the support frames extend apart from each other so that food can be placed in and removed from the holding space. In some cases, in the closed position, the support frames extend side by side, and in some cases substantially parallel to each other, so that food cannot be placed in or removed from the holding space.

[0020] In some cases, the holder member support includes a retaining arrangement that holds the frame in a closed position. In some cases, the retaining arrangement includes one or more catches, which may be made of magnetic material.

[0034] In some cases, the heat source or each heat source includes a heat generation region on which radiant heat energy is generated, and this region can be substantially flat and can extend substantially within the heat source plane. In some cases, the heat source plane can extend substantially parallel to the holding space plane and be spaced apart from the holding space plane.

[0035] In some cases, the heat generation region may correspond in shape to the retaining space and may be similar in size to the retaining space (possibly ±10%).

[0043] In some cases, the device includes one or more heat source mounting sections. In some cases, a heat source mounting section or each heat source mounting section may mount one heat source each. In some cases, a heat source mounting section or each heat source mounting section may mount one heat generating device each.

[0044] In some cases, each heat source mounting section or each heat source mounting section is positioned to allow for one movement of each heat source, possibly linear movement, and possibly movement toward and away from the holder mounting section.

[0046] In some cases, the heat source mounting section or each heat source mounting section includes a mounting arm. The mounting arm extends rearward from each heat source, and in some cases substantially horizontally.

[0047] In some cases, the apparatus includes a drive (e.g., a motor) for moving the heat source or each heat source toward and toward the holder mounting portion along a direction that may be substantially perpendicular to the holding space plane (in some cases laterally, in some cases linearly, in some cases substantially horizontally). In some cases, the drive is connected to the heat source mounting portion or each heat source mounting portion.

[0048] In some cases, the drive unit or each drive unit is positioned to allow for the gradual lateral movement of its respective heat source.

[0056] In some cases, the heat source mounting section or each heat source mounting section may be positioned to allow the user to select different orientations of the heat source(s) relative to the holder mounting section. In some cases, the heat source mounting section or each heat source mounting section may be positioned to allow each heat source to move between vertical orientation, angled (inclined) orientation, and substantially horizontal orientation.

[0057] In some cases, the heat source mounting section or each heat source mounting section is positioned so that the heat source can be raised and lowered relative to the holder mounting section.

[0058] In some cases, the device may include a controller that can control the operation of the device.

[0060] In some cases, the controller may receive an input signal and provide one or more output signals that depend on the received input signal.

[0061] In some cases, the controller may receive an input signal and provide one or more heat source location output signals that depend on the received input signal.

In some cases, the controller provides a separate thermal output signal for each heat source to independently control the thermal output of each heat source.

[0066] In some cases, the controller provides a single heat source position output signal to control the position of all heat sources. In other cases, the controller provides a separate heat source position output signal for each heat source to independently control the thermal position of each heat source.

[0067] In some cases, during cooking, the heat source position output signal moves each heat source to the cooking position, which can be between the inner and outer positions.

[0068] In some cases, the heat source position output signal moves each heat source between multiple cooking positions during the cooking process.

[0069] In some cases, the device (preferably the holder mounting section) includes a drip tray arrangement for capturing substances released from food during cooking (e.g., fat, grease, food particles, etc.). The drip tray arrangement may include a removable drip tray, which may be positioned directly below the holder receiving space.

[0078] In drawings, where multiple examples of the same or similar features exist, reference numbers are assigned to only one or a portion of the typical examples of the features for clarity. [Modes for carrying out the invention]

[0079] Figures 1 to 16 show a grilling apparatus 10 which includes the following: • A heat source 12 that generates radiant heat energy that moves along the heat path during use. • In the loaded state, the holder 14 holds the food 16. • And a holder mounting section 20 for mounting the holder 14 within the heat path when the device 10 is in a cooking state.

[0080] Figures 1 to 13B show a grilling device 10 with a grill configuration.

[0081] In the illustrated example, the apparatus 10 includes a pair of heat sources 12, and the holder mounting section 20 positions the holder 14 at a predetermined location within the heat path between the heat sources 12.

[0082] The holder 14 defines the holding space 18. In the loaded state, the food 16 is placed within the holding space 18. In the unloaded state, the holding space 18 is empty.

[0083] The holder 14 is movable between an open state (where the food 16 can be placed in the holding space 18 and removed from the holding space 18) and a closed state (where the food 16 cannot be placed in the holding space 18 and cannot be removed from the holding space 18).

[0084] The holding space 18 has a length 140, a width 142, and a thickness 144. The length 140 and width 142 are greater than the thickness 144. The length 140 and width 142 extend within the holding space plane 22. The thickness 144 extends perpendicular to the holding space plane 22. In the illustrated example, in the cooking state, the holding space plane 22 is substantially vertically oriented.

[0085] The holder 14 includes a pair of holder members 24. A holding space 18 is defined between the holder members 24. In the loaded state, both holder members 24 are positioned in contact with the food 16.

[0086] The holder 14 includes a holder member support portion 26. Both holder members 24 are mounted to the holder member support portion 26 by sliding. The holder member support portion 26 includes a support rod 28, and both holder members 24 slide along the support rod 28.

[0087] The holder member support section 26 includes an elastic member 30 that biases the holder members 24 toward each other and, in one example, can apply holding pressure to the food 16. One elastic member 30 is attached to each support rod 28. Each elastic member 30 may include a spring.

[0088] The holder member support portion 26 includes a centering mechanism 32. The centering mechanism 32 automatically centers the holder member 24 (and therefore the holding space 18) within the holder member support portion 26. The centering mechanism 32 includes a support rod 28 and an elastic member 30.

[0089] The holder member support section 26 includes a pair of support frames 34. Each support frame 34 supports one of the holder members 24, and each support frame 34 includes a support rod 28.

[0090] Referring to Figures 13A and 13B, each holder member 24 is detachably attached to each support frame 34 at each upper corner by a suspension arrangement 156, and each of them may include a suspension magnet 158.

[0091] Each suspension arrangement 156 includes a suspension member 162 defining a suspension hole 164 that receives one of the support rods 28, a suspension magnet 158 ​​attached to the suspension member 162 by screws (not shown), a heat shield washer 160, and a fixing member 166 positioned to be attracted to the suspension magnet 158.

[0092] Each holder member 24 defines a washer receiving hole 168 that can receive a heat shield washer 160.

[0093] The fixing member 166 has dimensions (for example, diameter) larger than the washer receiving hole 168 and holds the holder member 24 in place, but is designed to be easily removed for cleaning.

[0094] In the illustrated example, each suspension member 162 includes a vertically extending suspension member 162V that extends along one side of the support frame 34 between the upper and lower corners. In another embodiment, each suspension member 162 includes two vertically extending suspension members 162V and two horizontally extending suspension members 162H (shown by dashed lines in Figure 5) that extend along the upper and lower sides of the support frame 34, so that each suspension member 162 extends along four sides of the support frame 34.

[0095] The holder 14 includes a holder surface 170 that directs heat toward the food 16 in the holding space 18. In the illustrated example, the holder surface 170 is the surface of the support frame 34.

[0096] The holder member support portion 26 includes a hinge 36 that connects the two support frames 34 so that they are hinged together. In the open state shown in Figure 3, the support frames 34 extend apart from each other, allowing food 16 to be placed in and removed from the holding space 18. In the closed state, the support frames 34 extend side by side and substantially parallel to each other, preventing food 16 from being placed in and removed from the holding space 18.

[0097] The holder member support portion 26 includes a holding arrangement 38 that holds the frame 34 in a closed state. The holding arrangement 38 includes one or more catches 40, which may be made of magnetic material. In the illustrated example, the holding arrangement 38 includes two pairs of magnetic catches 40, with one pair positioned on each frame 34.

[0098] The holder member support portion 26 includes a handle 42. The handle 42 extends forward for the user to grasp when inserted. In the illustrated example, the handle 42 includes two handle portions 42A, each containing a part of one of the frames 34. In the closed position, the handle portions 42A define a handle opening 44 between them.

[0099] The holder member support portion 26 includes a thermocouple mounting forming portion 94 for attaching a thermocouple 48. The thermocouple mounting forming portion 94 defines a path 96 in which the thermocouple 48 can be positioned. The path 96 extends rearward from the front surface 116 of the holder member support portion 26 toward the holding space 18. Each frame 34 defines a portion 98 of the path 96.

[0100] The holder mounting section 20 defines a holder receiving space 50 in which the holder is positioned in a predetermined location relative to the heat source(s). The holder 14 is movable between an inserted state (the holder 14 is placed within the holder receiving space 50) and a removed state (the holder 14 is removed from the holder receiving space 50).

[0101] The holder mounting section 20 includes a base 52, on which the holder 14 is placed in an inserted state. The base 52 is positioned below the heat source 12.

[0102] The holder mounting section 20 includes a guide forming section 54 that guides the holder 14 as it moves between the inserted and removed states. The guide forming section 54 includes a pair of spaced-apart upright guide walls 56 extending upward from the base 52. In the inserted state, the holder 14 is positioned between the guide walls 56. Each of the guide walls 56 includes a positioning section 58. The positioning section 58 fits relatively snugly (ideally a sliding fit) to the holder 14 in the inserted state so that the holder 14 is positioned in a consistently repeatable position relative to the heat source 12. In the illustrated example, each guide wall 56 includes an angled entrance section 60. The angled entrance sections 60 spread outwards from each other.

[0103] The device 10 (preferably the holder mounting section 20) may include a drip tray arrangement 200 that includes a removable drip tray 152 for capturing substances released from food during cooking (e.g., fat, grease, food particles, etc.). The drip tray 152 is positioned directly below the holder receiving space 50.

[0104] Both support frames 34 define a drip opening 218 (see Figure 5) so that substances released from the food during cooking can be discharged into the drip tray 152.

[0105] The device 10 includes a thickness sensor 62 for displaying the thickness of the food 16.

[0106] The apparatus 10 includes a position measuring device 64 for measuring the position of one or both of the holder members 24. In the illustrated example, the position measuring device 64 measures the position of one of the holder members 24. The position measuring device 64 may include optical sensing means 66 (e.g., a laser) that forms a measuring beam 134 when in use.

[0107] The thickness sensor 62 includes a position measuring device 64.

[0108] The device 10 includes a position measuring device mounting section 70 for fixing the position measuring device 64 to the holder mounting section 20. In the illustrated example, the position measuring device mounting section 70 may include a housing frame 138. The position measuring device 64 measures the distance between one of the holder members 24 and the position measuring device 64 in the inserted and loaded states.

[0109] Each heat source 12 includes a heat generation region 74, on which radiant thermal energy is generated in a cooking state. The heat generation region 74 may be substantially flat and may extend substantially within the heat source plane 76. The heat source plane 76 extends substantially parallel to the holding space plane 22 and is positioned at a distance from the holding space plane 22.

[0110] The heat generation region 74 corresponds in shape to the holding space 18 and is the same size as the holding space 18; in one example, it can be the same size within ±10%.

[0111] The heat source plane 76 is substantially oriented vertically.

[0112] Each heat source 12 includes one heat generating device 78 which may include a burner or element 80, and includes a heat generating area 74.

[0113] Each heat source 12 is movable between an outer position and an inner position, moving closer to and away from the holder mounting portion 20. In the illustrated example, the device 10 is arranged such that the movement of each heat source 12 is independent of the others.

[0114] In another example, the apparatus 10 can be arranged so that the heat source 12 moves together simultaneously. The movement can be substantially the same in amount but in opposite directions.

[0115] The device 10 includes one or more heat source mounting sections 82. In the illustrated example, the device 10 includes two heat source mounting sections 82, each of which is fitted with one heat generating device 78.

[0116] In the illustrated example, each heat source mounting section 82 is positioned to allow one linear heat source 12 to move towards or away from the holder mounting section 20.

[0117] The apparatus 10 includes a housing frame 138. Each heat source mounting section includes a track 146 supported by the housing frame 138 and a roller 148. The roller 148 moves along the track 146 and supports each heat source 12.

[0118] Each heat source mounting section 82 includes a mounting arm 84. The mounting arm 84 extends rearward from each heat source 12, substantially horizontally (in the illustrated example).

[0119] The apparatus 10 includes a drive unit 86 (e.g., a motor) for moving the heat source 12 toward and toward the holder mounting portion 20. The movement of the heat source 12 is lateral, linear, substantially horizontal, and substantially perpendicular to the holding space plane 22. The drive unit 86 is connected to each heat source mounting portion 82.

[0120] The drive system may include a stepping motor, or it may include a servo motor.

[0121] In another example (not shown), the drive system may include a linear drive system, which may include a linear actuator.

[0122] In the illustrated example, each heat source mounting section 82 includes a linear drive converter 88 that converts rotational motion (e.g., from a motor) into linear motion. The mounting arm 84 is connected to and supported by the linear drive converter 88.

[0123] The linear drive converter 88 may include a threaded shaft 90 and a threaded drive connector 92. The threaded drive connector 92 is mounted on the threaded shaft 90 and supports a mounting arm 84.

[0124] In the illustrated example, each mounting arm 84 is connected to a separate drive unit 86 via a separate linear drive converter 88 and driven by this drive unit 86. Advantageously, this allows the heat sources 12 to be moved independently of each other, expanding the range of possible cooking options.

[0125] In another example, the mounting arms 84 can be driven by a common drive unit 86, which can drive a common threaded shaft 90 having two parts. One part has threads extending in one direction, and the other part has threads extending in the opposite direction. Each part drives one of the mounting arms 84, causing the mounting arms 84 to move together, but in opposite directions.

[0126] Linear drive converters may include main screws, ball screws, threaded nuts and / or nut blocks, belt drives, or rack and pinion systems.

[0127] For example, a linear drive converter includes a main screw with a screw pitch of 6 mm or less, which may be 2 mm or more in some cases, and preferably 4 mm.

[0128] In one example, the drive unit and heat source mounting section are arranged to provide a positioning accuracy of ±2.0 mm, more preferably ±0.5 mm, and optimally ±0.2 mm for the heat source.

[0129] The device 10 includes a controller 46 that controls the operation of the device 10. The controller 46 receives an input signal 100 and provides one or more output signals 110 that depend on the received input signal 100.

[0130] The input signal 100 may include a thickness indication input signal 102 provided by the thickness sensor 62. In the illustrated example, the thickness indication input signal 102 is not derived from an actual measurement of the food thickness, but from one measurement position on the holder member 24 by the position measuring device 64. In the illustrated example, this derivation takes into account that the holder member 24 is automatically centered within the holder member support 26, and that the holder member support 26 is repeatedly and relatively accurately positioned within the holder mounting 20. Therefore, in the loaded state, this arrangement places the food 16 centered between the holder member support 26 and the holder mounting 20.

[0131] The input signal 100 includes an internal food temperature input signal 104 provided by a thermocouple 48.

[0132] The input signal 100 includes one or more user input signals 106, which may include a food type input signal 108 (for example, indicating beef, pork, chicken, etc.) and an input signal 109 indicating the degree of cooking requested by the user (for example, well, medium, rare, etc.).

[0133] The input signal 100 may also include the weight, color, texture, water content, and fat content of the food.

[0134] The output signal 110 may include a heat output signal 112 that controls the heat output of each heat source 12. In one example, the heat output of the heat sources 12 is controlled together by a single signal. In another example, the controller 46 provides each heat source 12 with a separate heat output signal 112. In the latter case, the heat output of different heat sources can be controlled independently of each other, enabling a wider range of cooking options.

[0135] The output signal 110 includes a heat source position output signal 114 for controlling the position of the heat source(s) 12. In one example, the positions of the heat sources 12 are controlled together by a single signal 114. In another example, the controller 46 provides each heat source 12 with a separate position output signal 114. In the latter case, the positions of different heat sources 12 can be controlled independently of each other, enabling a wider range of cooking options.

[0136] The device 10 may include a user interface device 122 that can enable the input of user input signals 106 and include a touchscreen that can display user output signals 136. The user output signals 136 may include cooking parameters (e.g., internal temperature of food 16, estimated end time of cooking, remaining cooking time, etc.) and may be informational messages, warning messages, and alarm signals.

[0137] The device 10 may include a housing 124 that houses the components of the device 10 as described above. The housing 124 defines an access opening 126 into which the holder 14 can be inserted and removed from the holder receiving space 50, and a ventilation hole 128 for releasing heat during use.

[0138] The housing 124 may include a housing base 182 which can be in the form of a plate. The housing 124 may include side walls 188 extending upward from the housing base 182 and legs 184 extending downward from the housing base 182 to space the housing base 182 away from the support surface 190, thereby defining a gap 186 between the support surface 190 (Figure 1) and the housing base 182.

[0139] The device 10 may include a thermal barrier 172 to block the heat flow away from the food 16 during use. The thermal barrier 172 may include a curtain 174. In the illustrated example, the device 10 may include one curtain 174. The curtain 174 may be extendable and can be attached at each end to one of the different mounting arms 84. The curtain 174 may include concertina pleats 176.

[0140] The thermal barrier 172 may include a partition wall 208 extending between the heat source 12 and the low-temperature zone 212 (located behind the heat source 12). The drive unit 86 and the linear drive converter 88 may be located within the low-temperature zone 212. The apparatus 10 includes gas supply source components 214 (e.g., piping, connectors, valves, etc.) located within the low-temperature zone 212.

[0141] In the cooking state, the drip tray 152 is positioned between the guide wall positioning sections 58 and can be removed from there for emptying / cleaning by simply lifting it upward and then lifting it forward through the housing access opening 126. The drip tray 152 may include a forward-projecting handle 202 (in the illustrated example, in the form of a tab) to assist the user in gripping it.

[0142] When in use When in use, the holder 14 is initially detached, unattached, and open, as shown in Figure 3, and the support frames 34 extend away from each other. For convenience, the holder 14 can be placed flat on a surface (e.g., a table or worktop).

[0143] In the unloaded state, the holder member 24 is biased inward by a spring 30 that biases the holder member 24 inward along the rod 28.

[0144] In one method of use, the thermocouple 48 is inserted into the food 16, the food 16 is placed in the holding space 18 with contact to one of the holder members 24, and the holder 14 is moved to the loaded state. The thermocouple 48 is positioned in one of the path portions 98.

[0145] Next, as shown in Figure 4, the holder 14 moves to the closed position by rotating the support frame 34 around the hinge 36 so that they extend parallel to each other.

[0146] When the holder 14 is in the closed and loaded state, the holder member 24 moves outward due to the presence of the food 16 in the holding space 18, compressing the spring 30 so that the holder member 24 applies holding pressure to the food 16. This ensures that the food 16 is held securely when the holder 14 is positioned vertically.

[0147] When both heat sources 12 are in the outward position and the holder 14 is in the closed and loaded position, the holder 14 is moved to the inserted position by placing it on the base 52 between the guide wall inlet portions 60, and then sliding the holder 14 horizontally backward through the front of the device to position it in the holder receiving space 50 between the guide wall positioning portions 58.

[0148] Advantageously, the holder mounting section secures the holder 14 to a predetermined position with lateral accuracy (i.e., in the direction perpendicular to the holding space plane) of ±3 mm, more preferably ±2 mm, and optimally ±0.5 mm. In this way, the holder 14 is accurately and stably positioned in the cooking state.

[0149] The device 10 may include a position magnet 154 (Figure 12) that can be attached to the housing frame 138. The position magnet 154 can attract the holder 14, pull it into the correct position, and provide the user with tactile feedback and a sense of security that the holder 14 is fully inserted.

[0150] In the closed state, the thermocouple 48 extends forward from the food 16, enters the handle opening 44 along the path 96, and passes through the handle opening 44.

[0151] Next, the thermocouple 48 can be connected to the controller 46 by a wired connection (not shown) or a wireless connection (not shown) to provide an internal food temperature input signal 104.

[0152] With the holder 14 inserted, the controller 46 is programmed by the user via the user interface device 122 using a food type input signal 108 and a required cooking level input signal 109.

[0153] As described above, when the holder 14 is in the closed state, loaded state, and inserted state, the position measuring device 64 measures the position of one of the holder members 24 and provides a thickness display input signal 102.

[0154] The controller 46 provides a heat output signal 112 to control the operation of the heat source 12 and a heat source position output signal 114 to control the position of the heat source 12. To start cooking, the controller 46 moves the heat source 12 from the outer position to the inner cooking position, and the heat source 12 moves from the off state to the heated state.

[0155] The cooking position may depend on the thickness 16 of the food. In one example, the controller 46 has a library of stored offset values, which can be predetermined values ​​relating to the offset distance between the food 16 and the heat source 12 for different food types.

[0156] For example, if the food item 16 is a beef steak with a thickness of 12 mm, the offset value on each side can be 50 mm, and the cooking position of the heat source can be 56 mm away from the center line of the holder mounting portion 20 on each side (12 / 2 + 50 = 56 mm).

[0157] In one example, each heat source 12 may include a gas burner 80 that can be ignited by an igniter (not shown), and a controller 46 can control the volumetric gas supply to the burner 80.

[0158] The controller 46 can monitor the internal food temperature input signal 104 provided by the thermocouple 48 until the limit temperature is reached, at which point the controller 46 can move the burner 80 to the off position and outward position. This ensures that the cooking time is accurate and prevents overcooking.

[0159] In another example, the cooking time is calculated by the controller 46 without monitoring the internal food temperature.

[0160] The applicant has recognized that when using high heat output to obtain fast cooking times, the precision of positioning between the holder (and food) and the burner is crucial. Therefore, this device allows both the holder and the heat source to be positioned relative to each other with high precision, repeatability, and consistency.

[0161] The applicant has found that the device 10 offers a great deal of operational flexibility. In one operating mode, the user can manually control the heat output and heat source position. In another operating mode, the controller 46 can be programmed to use cooking profiles that allow the heat output and heat source position to be varied during cooking. During cooking, the controller 46 can change the heat output and heat source position. For example, the heat source position output signal 114 can be varied to move each heat source 12 between multiple cooking positions in the cooking state. The heat output can be pulsed or periodically increased or decreased. Cooking can be stopped when a predetermined "carryover" internal temperature is reached. This temperature is the temperature at which food continues to cook even after being removed from the heat.

[0162] advantage The applicant has found that this device allows even inexperienced users to cook food accurately, preventing / reducing overcooking, drying, and undercooking, thereby reducing the risk of waste and food poisoning, and consequently reducing the risk of users feeling embarrassed / anxious at parties and barbecues.

[0163] Surprisingly, the applicant found that cooking time is dramatically reduced because both sides of the food can be exposed to high heat at once, rather than having to cook both sides sequentially as in conventional arrangements. This helps to retain juices and flavor, and therefore improves the quality of the cooked food.

[0164] The applicant has surprisingly discovered that when food and the heat source are oriented vertically, more juices are retained within the food, resulting in improved flavor. Furthermore, in this vertical orientation, steam is released rather than trapped between the grill pan and the food. As a result, the steam lowers the temperature of the cooking oil in the grill pan, improving flavor and shortening cooking time.

[0165] The applicant has found that rapid and thorough cooking reduces the amount of energy required.

[0166] Pizza / Baking Composition The device 10 can be moved between a grill configuration (as shown in Figures 1 to 13) and a pizza / baking configuration (as shown in Figure 14). In the pizza / baking configuration, the holder 14 includes a pizza / baking tray 130.

[0167] In the pizza / baking configuration, the food 16 (e.g., pizza) is placed on the tray 130 and positioned between the heat sources 12. The heat sources 12 can be operated in an outer position to maximize the size of the tray 130, or their cooking position can be adjusted to the size of the tray 130. The tray 130 may include a guide forming section 54 and a positioning forming section 132 whose size and shape correspond to it. A thermocouple 48 can be placed inside the food 16.

[0168] The device 10 includes one or more doors 178 (Figure 2) for closing the housing access opening 126.

[0169] Other aspects of this operational configuration can be the same as those described above.

[0170] Rotisserie composition The apparatus 10 can be moved between a grill configuration and a rotisserie configuration. In the rotisserie configuration as shown in Figures 15 and 16, the holder 14 includes the rotisserie 150.

[0171] In the rotisserie configuration, the holder mounting section 20 can move laterally toward one of the heat sources 12 and away from the other to accommodate food on the rotisserie 150, and only the other heat source 12 operates during cooking.

[0172] Other aspects of this operational configuration can be the same as those described above.

[0173] Second Embodiment Figures 18 to 21 show a second grilling apparatus 210, which is another embodiment of the present invention. Many of its features are the same as those already described in relation to the embodiments in Figures 1 to 16. Therefore, for simplicity, the following embodiments will only describe the differences from the embodiments already described. Where the features are the same or similar, the same reference numerals will be used, and the features will not be described again.

[0174] The second grilling device 210 includes a drip tray arrangement 200. The drip tray arrangement 200 includes a removable drip tray 152 and a drip tray mounting section 180. The drip tray mounting section 180 slides the drip tray 152 to the underside of a housing base 182, and the drip tray 152 is slidably movable between a fully inserted state and a fully removed state.

[0175] The drip tray configuration 200 includes a removable funnel 192. The funnel 192 includes an inclined side wall 194 that slopes downward toward a funnel opening (not shown) located at the front of the device 210.

[0176] The drip tray mounting section 180 includes a pair of support members 198 (which may have an L-shaped cross-section) that support the drip tray 152 below the funnel 192.

[0177] During cooking, the drip tray 152 is positioned fully inserted on the support member 198 directly below the funnel opening. Substances released from the food during cooking are captured by the funnel 192, and liquids (e.g., hot oils or fats) can drip into the drip tray 152 through the funnel opening. After cooking, the drip tray 152 is moved by sliding along the support member 198 and lifted high enough to be completely removed, allowing it to be emptied and cleaned.

[0178] The funnel 192 can be removed from between the guide wall positioning sections 58 and emptied / cleaned by simply lifting it upward and then lifting it forward through the housing access opening 126.

[0179] The drip tray 152 and / or funnel 192 may include a forward-projecting handle 202 (in the illustrated example, in the form of a tab) to assist the user in gripping it.

[0180] Advantageously, the applicant has found that the drip tray arrangement 200 of this embodiment facilitates the recovery of ingredients released during cooking, particularly by separating the liquid from solid particles.

[0181] In the second grilling device 210, the drive unit 86 is positioned directly beneath the heat source 12, rather than on one side.

[0182] In this embodiment, each of the drive units 86 and each of the linear drive converters 88 are positioned within drive slots 204 defined by the housing base 182. The mounting arm 84 includes a pair of lateral portions 84A extending in opposite directions laterally. The lateral portions 84A are respectively connected to vertical portions 84B extending upward through the mounting arm slot 206. The mounting arm slot 206 is defined by the housing base 182 and supports each of the heat sources 12. Thus, each of the heat generating units 78 is supported at two ends by one mounting arm 84, improving stability.

[0183] The device 210 includes a pair of covers 216. One cover 216 is fixed to the underside of the housing base 182 (for example, by appropriate fasteners such as screws) and covers each drive unit 86 and its respective heat source mounting section 82.

[0184] This arrangement of the heat source mounting section 82 and the drive units 86 offers several advantages. Each drive unit 86 is closer to its respective heat source 12. Each drive unit 86 is directly beneath its respective heat source 12. Each heat source 12 is supported at two ends. These features result in a more stable arrangement for supporting and moving the heat sources 12. It is also advantageous that the drive units 86 are positioned away from the gas supply source component 214.

[0185] Other changes Various other modifications can be made without departing from the scope of the present invention. The apparatus and its various components can be of any suitable size and shape and can be formed from any suitable material (within the scope of the specific provisions herein).

[0186] In some examples, the drive system may include a linear drive configuration (e.g., a linear motor) or a cylinder / piston configuration (which may be pneumatic or hydraulic). The drive system may also include an actuator and any suitable means of transmission (e.g., a drive belt).

[0187] A linear drive converter may include a main screw, a ball screw, a threaded nut, and / or a nut block.

[0188] The heat source mounting section or each heat source mounting section can be positioned to allow the user to select different orientations of the heat source(s) relative to the holder mounting section. In one example, the heat source mounting section allows each heat source to be moved between the aforementioned vertical orientation, angled (inclined) orientation, and substantially horizontal orientation.

[0189] The heat source mounting section or each heat source mounting section can be arranged so that the heat source can be raised and lowered relative to the holder mounting section.

[0190] The device can be made portable and battery-powered.

[0191] Any feature or step of any illustrated or described embodiment can be combined in any suitable manner within the scope of the overall disclosure of this document.

[0192] Final findings Thus, a grilling device is provided that offers many advantages compared to conventional arrangements. This device improves food cooking control, allowing relatively inexperienced users to grill food (e.g., steak and chicken) accurately and reliably. The internal food temperature is monitored, and the heat output and position of the heat source can be changed. Vertical orientation of the food and heat source reduces cooking time and improves flavor.
