Due to this, the existing conventional cooking devices may not function continuously during movement of vehicles, which affects the adaptability and practicability of the cooking device. Accordingly, the cooking device herein may overcome these issues.
- The cooking device of the present disclosure includes a trailer configured to couple with a vehicle. A housing is supported by the trailer and defines a heating chamber. A heat source is disposed within the heating chamber. A controller is operably coupled with an auger assembly to direct fuel to the heat source for heating the heating chamber. A power actuator is operably coupled with the control unit and configured to accept electrical power from two or more power supplies and provide power to the controller from one of the two or more of sources, which may assist in low power operation of the vehicle movable cooking device, normal work during movement of the vehicle, broadening the applicable scenarios of the vehicle movable cooking device, and being suitable for various uses.
- Referring now to
FIGS. 1 and 2 , acooking device 10 includes ahousing 12 that defines aheating chamber 14 in which food items to be prepared may be placed. In some examples, thehousing 12 may include alower portion 16, anupper portion 18, and amovable lid 20. Themovable lid 20 provides and inhibits access to theheating chamber 14 and may be operably coupled to theupper portion 18 through a hinge. Ahandle 22 can be positioned on thelid 20 to enable a user to move thelid 20 between an open position, an example of which is illustrated inFIG. 1 , and a closed position, an example of which is illustrated inFIG. 2 . During operation, thelid 20 can be opened to place food items on one ormore racks 24 within theheating chamber 14. Thelid 20 can then be closed so as to retain heat and/or smoke supplied to theheating chamber 14 for food preparation. To assist in moving thelid 20 between the open and closed positions, a lift assist 26 may be operably coupled with thelid 20 and a stationary component of thecooking device 10, such as thelower portion 16 of thehousing 12 and/or ashelf 28 extending from thelower portion 16 of thehousing 12. The lift assist 26 may provide upward vertical force on thelid 20 through hydraulics, pneumatics, spring mechanics, motors, and/or any other practicable device. - When the
lid 20 is positioned in the closed position, one or more lid latches 30 may maintain thelid 20 in the closed position. The lid latches 30 may be configured to retain thelid 20 while thecooking device 10 is transported, which may occur with vehicle assistance. The lid latches 30 may also retain thelid 20 such that additional heat is preserved within theheating chamber 14 when heated. - The
cooking device 10 may also include one ormore exhaust conduits 32 to remove heat and/or smoke from theheating chamber 14 that is generated during the food preparation. Theexhaust conduit 32 may be selectively closed and/or altered to adjust the heating characteristics within thechamber 14. In some instances, acover 34 may be movably coupled with theexhaust conduit 32 to alter an exit opening of theexhaust conduit 32. - The
cooking device 10 may be any type of device cooking device. As non-limiting examples, thecooking device 10 may a grill, smoker, air fryer, oven, brazier, steamer, roaster, fryer, broiler, stove, and/or toaster oven. While thecooking device 10 may be any type ofcooking device 10, the present disclosure will be described with continuing reference to a grill, which may utilize pellets as afuel 40. Those of ordinary skill in the art will be able to apply the features set forth herein to other types ofcooking devices 10 using the description of the present disclosure in the non-limiting example of a grill. - Various components of the
cooking device 10 may be made of any desired heat-resistant material(s). As non-limiting examples, various portions of thecooking device 10 may be made of stainless steel and/or cast iron. Thecooking device 10 can be shaped to have an enclosed inner chamber, i.e., theheating chamber 14, which may be heated by aheat source 36. Theheat source 36 can include anigniter 38 that may independently produce heat. Additionally, and/or alternatively, theigniter 38 may ignite afuel 40 and/or sustain a burning of thefuel 40 to produce heat within theheating chamber 14, which may occur in a burn box. - In some examples, the
fuel 40 may be stored in ahopper 42, or any other type of container, and may contain wood pellets for producing the heat and/or smoke. In some instances, the pellets are loaded into thehopper 42 through movement of apanel 44 from a closed position to an open position thereby providing access into thehopper 42. When thepanel 44 is positioned in the closed position, one or more panel latches 46 may maintain thepanel 44 in the closed position. The panel latches 46 may be configured to retain thelid 20 while thecooking device 10 is transported, which may occur with vehicle assistance. Moreover, the panel latches 46 may be locked to prevent tampering with the pellets when locked. - The pellets may be transported from the
hopper 42 using anauger assembly 48. Theauger assembly 48 may include anauger 50 centrally disposed in a channel 52 that may extend along an underside of theheating chamber 14. The channel 52 includes openings or the like that place the channel 52 and/or theauger 50 in gaseous communication with theheating chamber 14. When theauger 50 is rotated within the channel 52 by amotor 54, pellets are drawn from thehopper 42 and transported via theauger 50 through the channel 52. One or more igniters 38 (e.g., electrical igniters) locally heat the wood pellets and cause the pellets to emit heat and/or smoke for theheating chamber 14. After the consumption of the pellets, the channel 52 and theauger 50 may further transport the consumed pellets (or remains thereof) to a used pellet discharge port 154 (FIG. 6 ). At the usedpellet discharge port 154, the pellets can exit thecooking device 10. In some instances, a bucket 156 (FIG. 6 ), container, tray, or the like may be disposed at the usedpellet discharge port 154 to collect the pellet remains and/or food runoff that becomes detached from the food item while in theheating chamber 14. Theauger assembly 48 may further include one or more fans 88 (FIG. 4 ) that direct airflow through the channel 52 and/or through theheating chamber 14. - It will be appreciated that the
cooking device 10 of the present disclosure may use any desiredfuel 40 for heating theheating chamber 14. As non-limiting examples, thefuel 40 for thecooking device 10 may be wood (e.g., wood pellets), stick burners, natural gas, charcoal, gas, and/or an electrical heating unit. Theheat source 36 may sustain a temperature inside thecooking device 10 of around 100 to 800 degrees Fahrenheit for cooking the food items. In some examples, thecooking device 10 may be able to automatically (without human intervention after initiation) regulate the temperature inside thecooking device 10 to a predetermined set temperature or temperature range. - With further reference to
FIGS. 1 and 2 , thecooking device 10 further includes acontrol unit 56 for controlling various components of thecooking device 10, including, but not limited to, theauger assembly 48, theigniters 38, a fan 88 (FIG. 4 ), themotor 54, and/or any other electrically powered device within thecooking device 10. Thecontrol unit 56 may further include adisplay 58 for providing the status of the operation of thecooking device 10 and/or operational data such as configured a visual indication of the power supply being utilized, such as working time, heating chamber temperature, battery capacity and power supply voltage, and alarming when the set time is up or when the barbecue oven temperature is abnormal. Thecontrol unit 56 may further include aninput device 60 for accommodating user input, a cabinet temperature sensor for determining the temperature inside thechamber 14, a probe for determining the internal temperature of the food being cooked, a timer module for setting the cooking time for thecooking device 10, a probe temperature set module for setting the internal temperature of the food product based on the user's preference for the cooked food, a display control relay for powering thedisplay 58, and/or a heat source control relay for cycling the heat source ON and OFF. The probe may be electronically coupled with one or more input/output (I/O)ports 62 disposed on thecontrol unit 56. The I/O ports 62 may be configured in any manner and may interact and/or couple with a wide array of devices. - Still referring to
FIGS. 1 and 2 , thecooking device 10 may include and/or be integrated within atrailer 64 for the transportation/trailering of thecooking device 10. Thetrailer 64 includes a plurality offrame members 66 for supporting various components of thecooking device 10, such as thehousing 12, thecontrol unit 56, portions of theauger assembly 48, and/or any other component. Theframe members 66 may also define astorage space 68 disposed forwardly of thehousing 12. Ashelf 70 may be supported by theframe members 66 that define thestorage space 68. - A
tongue 72 may extend forwardly of theframe members 66 with ahitch coupler 74 is fixedly attached to an end portion thereof. Thehitch coupler 74 is configured to attach to ahitch assembly 76 of avehicle 78. Atrailer tongue jack 80 is affixed to thetongue 72. Thejack 80 can lift thehitch coupler 74 to assist in attachment of thecoupler 74 to thehitch assembly 76 of thevehicle 78 and/or level thecooking device 10, and/or thetrailer 64, once separated from thevehicle 78. - The
trailer 64 is suspended by springs (e.g., “leaf” springs). The springs can be attached to theframe members 66. Anelongated axle 82 can extend perpendicularly to thetongue 72 andwheels 84 are attached to theelongated axle 82. Theaxle 82 may be of any shape, form, or structure. In addition, while theframe members 66 ofFIGS. 1 and 2 define a rectangular shape, thetrailer 64 may be of any shape with any number of sides. Moreover, while thetrailer 64 ofFIGS. 1 and 2 includes two wheels (i.e., the wheels 84), any number of wheels may be used. For example, thetrailer 64 may include a tandem axle in which four wheels would be used. - Referring to
FIG. 3 , thecontrol unit 56 may include acontroller 86 for controlling the various functions and components of thecooking device 10. Thecontroller 86 may have power supplied thereto through apower actuator 90 that may include afirst branch 92, asecond branch 94, and athird branch 96 which are electrically connected with thecontroller 86 after being connected in parallel with each other. Thefirst branch 92 may be connected with a cookingdevice power supply 98, thesecond branch 94 may be configured to connect with thevehicle power supply 100, and thethird branch 96 may be configured to couple with anexternal power supply 102 and arectifier 104 in series. In some examples, however, therectifier 104 may be absent from thethird branch 96. In various examples, the power actuator electrically powers at least one of thecontrol unit 56 or theheat source 36 at a set power. Thepower actuator 90 may additionally or alternatively power any other component of thecooking device 10. - In some instances, the cooking
device power supply 98 may be located within thecooking device 10 and/or otherwise disposed on thetrailer 64. Thevehicle power supply 100 may be a battery, or other power storage device, disposed within thevehicle 78 and/or a power generating device within thevehicle 78, such as an alternator. Theexternal power supply 102 supplies power from the grid and connects to, for example, a 102-volt alternating current (AC) power outlet that supplies power to thecontrol unit 56 and/or charges the cookingdevice power supply 98. Therectifier 104 converts the AC power from theexternal power supply 102 to direct current (DC) power, which may be stored in the cookingdevice power supply 98 and/or directed to thecontrol unit 56, through thepower actuator 90. - During operation of the
cooking device 10, the power supplied to thecooking device 10 can be flexibly or dynamically switched based on detected conditions through thepower actuator 90. Thepower actuator 90 may be configured to accept electrical power from two or more sources and provide power to thecontroller 86 from one of the two or more of sources. For example, the cookingdevice power supply 98 can be used to supply power when thecooking device 10 is separated from thevehicle 78. Thevehicle power supply 100 can be used to supply power when thecooking device 10 is operably coupled with thevehicle 78. Theexternal power supply 102 can be used to supply power when a fixedexternal power supply 102 is available. Through the use of various power supplies, thecooking device 10 may be able to function in many different environments and/or for longer durations of time when compared to conventional cooking devices. However, in some examples, thecooking device 10 can accept electrical power from a single source without departing from the scope of the present disclosure. - The cooking
device power supply 98 may include abattery control module 106, abattery monitor module 108, and abattery 110 operably coupled with thepower actuator 90. Thebattery 110 can include multiple cells or batteries (B1, B2, . . . BN, where N is an integer), which may be collectively referred to as the “battery 110.” The various batteries B1-N of thebattery 110 may have the same voltage or different voltages, such as 12V and/or 24V and may be configured as any type of the battery, such as alkaline type batteries, rechargeable batteries, lithium ion, nickel-cadmium, nickel-metal-hydride, button batteries, capacitors, and/or any other suitable power storage device. Thebattery control module 106 communicates with thecontroller 86 to assess the power demand of thecooking device 10. Based on the information received, thebattery control module 106 controls thebattery 110 of the cookingdevice power supply 98. Thebattery monitor module 108 monitors operating conditions within thebattery 110 of the cookingdevice power supply 98 and of each battery B1-N. As an example, thebattery monitor module 108 may monitor the charge-discharge rate of each battery B1-N, the temperature of thebattery 110, the state of charge (SOC) of each battery B1-N, and/or other information for determining the condition and the life of the batteries. Thebattery monitor module 108 may receive information from sensors disposed within thebattery 110, such as a temperature sensor for monitoring temperature within thebattery 110, a voltage sensor monitoring the voltage of each battery B1-N, or a charge current sensor for monitoring the current supplied to the battery for charging the battery. Based on the information from the sensors, and predetermined algorithms, thebattery monitor module 108 may determine each of the operating conditions. - Based on the operation conditions of the
battery 110, which may be determined by thebattery monitor module 108, thebattery control module 106 may determine if a battery B1-N needs to be charged, if a battery B1-N is defective, if a life of a battery B1-N has deteriorated, and/or other suitable condition for assessing the performance and quality of the batteries inbattery 110. Information regarding the condition of thebattery 110 and the batteries therein may be provided to thecontroller 86. As an example, if the performance of a given battery B1-N from thebattery 110 has deteriorated such that thebattery 110 is not able to maintain a charge for a predetermined amount of time or has a charge-discharge rate below a predetermined threshold, thebattery monitor module 108 may send information indicative of such condition to thecontroller 86. Thecontroller 86 may then notify a user of the low performingbattery 110 and recommend that thebattery 110 be replaced. For instance, thecontroller 86 may utilize thecontrol unit display 58 and/or a speaker 112 (FIG. 4 ), which may also be operably coupled with thecontrol unit 56, for notifying a user of the detected battery condition. - The
battery control module 106 controls each battery B1-N within the cookingdevice power supply 98 to provide power to one or more components of thecooking device 10 and/or to charge thebattery 110. The components may include, but are not limited to, thecontrol unit 56, thecontroller 86, theauger assembly 48, themotor 54, thefan 88, thedisplay 58, thespeaker 112, thebattery control module 106, thebattery monitor module 108, and/or any other device operably coupled with thecooking device 10 and/or supported on thetrailer 64 that uses electrical energy to perform a function. Generally, thecooking device 10 may include multiple components that require the same electrical voltage (i.e., a standard-power device) and may also include one or more other devices that may require a larger amount of electrical voltage (i.e., a high-power device). Thebattery control module 106 can control the batteries to supply power to both standard-power devices and high-power devices. In some instances, themotor 54 and/or thefan 88 may require the same voltage the voltage output of thevehicle power supply 100 and/or a portion of the batteries in the cookingdevice power supply 98. Accordingly, in some examples, anelectrical connector 116 from thevehicle 78 to a component of thecooking device 10 may power that device without any additional equipment. In addition, thebattery control module 106 may electrically couple the batteries with power supplied from thevehicle power supply 100 and/or theexternal power supply 102 to charge the batteries of the cookingdevice power supply 98. A DC-DC converter may be coupled to thebattery 110 for converting the power from thevehicle power supply 100 and/or theexternal power supply 102 to a requisite voltage level for charging thebattery 110. In some examples, thepower actuator 90 may include anovercurrent protection device 114, which may be configured as a fuse, an electromechanical circuit breaker, a solid state switch device, and/or any other practicable device. - The
vehicle power supply 100 may consist of one or more vehicle batteries that store electrical energy. Additionally, and/or alternatively, thevehicle power supply 100 may generate electrical power from an electrical energy producing device, such as an alternator, that is then supplied to thepower actuator 90. The alternator converts mechanical energy from an engine to electrical power for charging thevehicle 78 and/or the batteries of the cookingdevice power supply 98. A DC-DC converter may be coupled to the alternator for converting the power from the alternator to a requisite voltage level for charging thebattery 110 prior to the energy being delivered to the cookingdevice power supply 98. - As provided herein, the
power actuator 90 may additionally or alternatively be removably coupled with theexternal power supply 102, which may provide electrical power to thepower actuator 90 from an electrical power grid. Generally, the electrical grid is an electrical power system network that includes a remote generating plant, transmission lines, various substations, transformers, and/or distribution lines to supply power to a stationary location having a connection point. If a connection point is proximate thecooking device 10, aconnector 116 may be used to operably couple thepower actuator 90 to the connection point. Arectifier 104 may be disposed between the plug and thepower actuator 90 for converting AC power supplied from the connection point to DC power. - The
power actuator 90 may include arepository 118 that stores predetermined guidelines. Therepository 118 is a storage device, such as a non-volatile memory. The guidelines may determine which power supply supplies power to thecontroller 86 based on the available inputted power supplies. For example, the guidelines may provide that the external power is utilized as a primary power supply when electrically coupled to thepower actuator 90, thevehicle power supply 100 may be used as a secondary power supply when coupled to thepower actuator 90, and the cookingdevice power supply 98 is a tertiary power supply. The guidelines can additionally or alternatively indicate whether the batteries not being used are to be charged. The guidelines may take various suitable forms such as predefined look-up tables and/or control processes. - Using the guidelines and the operation condition of each battery B1-N provided by the
battery monitor module 108, thepower actuator 90 determines the operation of each battery B1-N. For example, thepower actuator 90 determines if the batteries B are to be coupled to a particular port to supply power to one or more components of thecooking device 10, which of the batteries B should be electrically coupled to each other and/or to the ports, and/or which of the batteries should be charged. Thepower actuator 90 then transmits a command signal to the control module of the cookingdevice power supply 98 for having the cookingdevice power supply 98 perform the electrical connection of the batteries. - In some examples, various other conditions may affect which power supply is to be used. For example, the
power actuator 90 may provide power to thecontrol unit 56 from the cookingdevice power supply 98 when thevehicle 78 is in motion and from thevehicle power supply 100 when thevehicle 78 is stationary. The motion of thevehicle 78 may be measured by an accelerometer, a device on thevehicle 78, the electronic device 132 (FIG. 4 ), and/or through any other method without departing from the teachings provided herein. - In various examples, the
cooking device 10 may include some devices that operate on AC power while others may operate on DC power. In such instances, power supplied from thepower actuator 90 to thecontroller 86 may be supplied to aninverter 122 prior to the being supplied to thecontroller 86 through a firstconductive lead 120 while power may be delivered to thecontroller 86 as DC power through parallel secondconductive lead 124. In some examples, the power supplied from thepower actuator 90 may be directed to the various components of thecooking device 10 rather than through thecontroller 86 and/or thecontrol unit 56. Moreover, thepower actuator 90 may dynamically provide power through one or bothleads power actuator 90 supplies power to thecontrol unit 56 and/or to amotor 54 within theauger assembly 48, theauger assembly 48 being configured to providefuel 40 to theheat source 36. - Referring to
FIG. 4 , in some examples, thecontroller 86 has aprocessor 126 andmemory 128, according to some examples.Logic 130 is stored within thememory 128 and includes one or more routines that is executed by theprocessor 126. Thecontroller 86 includes any combination of software and/or processing circuitry suitable for controlling various components of thecooking device 10 described herein including without limitation processors, microcontrollers, application-specific integrated circuits, programmable gate arrays, and any other digital and/or analog components, as well as combinations of the foregoing, along with inputs and outputs for transceiving control signals, drive signals, power signals, sensor signals, and so forth. All such computing devices and environments are intended to fall within the meaning of the term “controller” or “processor” as used herein unless a different meaning is explicitly provided or otherwise clear from the context. - In some examples, the
cooking device 10 may communicate via wired and/or wireless communication with one or more handheld orelectronic devices 132 through atransceiver 134. The communication may occur through one or more of any desired combination of wired (e.g., cable and fiber) and/or wireless communication mechanisms and any desired network topology (or topologies when multiple communication mechanisms are utilized). Exemplary wireless communication networks include a wireless transceiver (e.g., a BLUETOOTH module, a ZIGBEE transceiver, a Wi-Fi transceiver, an IrDA transceiver, an RFID transceiver, etc.), local area networks (LAN), and/or wide area networks (WAN), including the Internet, cellular, satellite, microwave, and radio frequency, providing data communication services. - With further reference to
FIG. 4 , thecontroller 86 receives power through thepower actuator 90 as provided herein. Thepower actuator 90 may receive power from one or more sources, including the cookingdevice power supply 98, theexternal power supply 102, and/or thevehicle power supply 100. As provided herein, each source may be utilized in a predefined manner when electrically coupled with thepower actuator 90. In operation, when powered, thecontroller 86 may activate/deactivate amotor 54 that rotates theauger 50 within theauger assembly 48 to movefuel 40 from thehopper 42 to theheat source 36. Themotor 54 may be configured as any type of motor, including, but not limited to, an AC brushless motor, a DC brushed motor, a DC brushless motor, a direct drive motor, a linear motor, a servo motor, a stepper motor, and/or any other practicable motor. In some examples, pulse width modulation (PWM) may be employed to vary the effective voltage or current to themotor 54. PWM controls themotor 54 with short pulses of voltage or current. These pulses are varied in duration to change the speed of themotor 54. The longer the pulses, the more torque themotor 54 can produce and visa versa. For example, if the output of a DC voltage source is twelve volts, and the PWM signal is on 25%, 50%, or 75% of the time, themotor 54 would receive the approximate average of three, six, and nine volts, respectively. - PWM is a way of digitally encoding analog signal levels. Through the use of high-resolution counters, the duty-cycle of a square wave is modulated to encode a specific analog signal level. The PWM signal is still digital, however, because at any given instant in time, the full DC supply is either ON or OFF. Many PWM motors require high PWM frequencies. The PWM period should be short relative to the motor's 54 response time to a change in the switched signal state. Common PWM frequencies may range from 1 kHz to 200 kHz, for example. The duty cycle is the ratio of the on-time in a given period to the period. A position or time derivative sensor, such as an encoder, may be coupled between the
motor 54 and thecontroller 86. The position or time derivative sensor provides positional, velocity, or acceleration feedback to thecontroller 86. Based on the feedback, thecontroller 86 may adjust the input to themotor 54, in this case adjust the PWM to themotor 54, in order to result in a desired positional move, motor speed, or motor acceleration, which may occur at a greater precision than an AC motor. - An
igniter 38 within theheat source 36 ignites thefuel 40 to generate heat/smoke within theheating chamber 14 that cooks a food item disposed therein. To assist in directing the heat/smoke through theheating chamber 14, thefan 88 may direct airflow through the channel 52 of theauger assembly 48 and into theheating chamber 14. Thefan 88 may be of any practicable type without departing from the teachings provided herein. Thecooking device 10 may be additionally or alternatively include a valve and/or another non-electronically powered device for regulating thefuel 40. In some examples, thefuel 40 may be remotely disposed from thecooking device 10 without departing from the teachings of the present disclosure. - The
electronic device 132 may be any one of a variety of computing devices and may include a processor and memory. The memory may store logic having one or more routines that is executable by the processor. For example, theelectronic device 132 may be a cell phone, mobile communication device, key fob, wearable device (e.g., fitness band, watch, glasses, jewelry, wallet), apparel (e.g., a tee shirt, gloves, shoes or other accessories), personal digital assistant, headphones and/or other devices that include capabilities for wireless communications and/or any wired communications protocols. - The
electronic device 132 may have anapplication 136 thereon and adisplay 138 may provide a graphical user interface (GUI) and/or various types of information to a user. The operation of the various components of thecooking device 10 may be altered through usage of theapplication 136 and/or information regarding the operation of the components may be illustrated on thedisplay 138. Theelectronic device 132 may likewise have any combination of software and/or processing circuitry suitable for controlling thecooking device 10 described herein including without limitation processors, microcontrollers, application-specific integrated circuits, programmable gate arrays, and any other digital and/or analog components, as well as combinations of the foregoing, along with inputs and outputs for transceiving control signals, drive signals, power signals, sensor signals, and so forth. - In some examples, the
electronic device 132 may be configured to receive user inputs via thetouchscreen circuitry 140 on thedisplay 138. The inputs may relate to a type of food item disposed within theheating chamber 14 and may be based on an automatic detection of the food item and/or user provided information as to a type of food item. In response, theapplication 136 and/or thecontroller 86 may provide suggested cooking characteristics. The inputs may also relate to a desired power supply, in which the user may override the guidelines provided in therepository 118. In some examples, the power supply used by thecooking device 10 may be varied based on the power needed for the user inputted instructions. Accordingly, usage of thecooking device 10 may be varied through usage of theapplication 136 in addition to or in lieu of usage of theinput device 60 and/or a predetermined activation sequence. In addition, theelectronic device 132 may also provide feedback information, such as visual, audible, and tactile alerts. The feedback information may be provided for any reason, including but not limited to, error notifications, power supply and/or percentages of power left within a power supply, food item cooked notifications, timing notifications, etc. - In some instances, the
cooking device 10 may include animaging system 142. In such instances, one or more imagers within theimaging system 142 may include an area-type image sensor, such as a CCD or a CMOS image sensor, and image-capturing optics that captures an image of an imaging field of view defined by the image-capturing optics. The captured image may be illustrated on thedisplay 138 of theelectronic device 132. In some instances, successive images may be captured and provided on thedisplay 138 to create a video. The images may be used to monitor the food item, to determine whether to alter a temperature of theheating chamber 14, to verify proper functioning of thecooking device 10, and/or for any other purpose. - Referring to
FIG. 5 , in some examples, thecooking device 10 may be communicatively coupled with one or more remote sites such as aremote server 144 via a network/cloud 146. The network/cloud 146 represents one or more systems by which thecooking device 10 may communicate with theremote server 144. Accordingly, the network/cloud 146 may be one or more of various wired or wireless communication mechanisms, including any desired combination of wired and/or wireless communication mechanisms and any desired network topology (or topologies when multiple communication mechanisms are utilized).Exemplary communication networks 146 include wireless communication networks (e.g., using Bluetooth, IEEE 802.11, etc.), local area networks (LAN) and/or wide area networks (WAN), including cellular networks, satellite networks, microwave networks, radio frequency networks, the Internet and the Web, which all may provide data communication services and/or cloud computing services. The Internet is generally a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. In contrast, the Web is generally one of the services communicated via the Internet. The Web is generally a collection of interconnected documents and other resources, linked by hyperlinks and URLs. In many technical illustrations when the precise location or interrelation of Internet resources are generally illustrated, extended networks such as the Internet are often depicted as a cloud (e.g. 148 inFIG. 5 ). The verbal image has been formalized in the newer concept of cloud computing. The National Institute of Standards and Technology (NIST) provides a definition of cloud computing as “a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” Although the Internet, the Web, and cloud computing are not exactly the same, these terms are generally used interchangeably herein, and they may be referred to collectively as the network/cloud 146. - The
server 144 may be one or more computer servers, each of which may include at least one processor and at least one memory, the memory storing instructions executable by the processor, including instructions for carrying out various steps and processes. Theserver 144 may include or be communicatively coupled to adata store 148 for storing collected data as well as instructions for operating thecooking device 10, the control unit 56 (FIG. 4 ), etc. that may be directed to and/or implemented by thecooking device 10 with or without intervention from a user and/or theelectronic device 132. - In some examples, the instructions may be inputted through the
electronic device 132 and relayed to theserver 144. Those instructions may be stored in theserver 144 and/ordata store 148. At various predefined periods and/or times, thecooking device 10 may communicate with theserver 144 through the network/cloud 146 to obtain the stored instructions, if any exist. Upon receiving the stored instructions, thecooking device 10 may implement the instructions. Theserver 144 may additionally store information related tomultiple cooking devices 10, food items, usage characteristics, errors, etc. and operate and/or provide instructions to thecooking device 10 in conjunction with the stored information with or without intervention from a user and/or theelectronic device 132. - With further reference to
FIG. 5 , theserver 144 also generally implements features that may enable thecooking device 10 to communicate with cloud-basedapplications 150. Communications from thecooking device 10 can be directed through the network/cloud 146 to theserver 144 and/or cloud-basedapplications 150 with or without anetworking device 152, such as a router and/or modem. Additionally, communications from the cloud-basedapplications 150, even though these communications may indicate one of thecooking device 10 as an intended recipient, can also be directed to theserver 144. The cloud-basedapplications 150 are generally any appropriate services orapplications 150 that are accessible through any part of the network/cloud 146 and may be capable of interacting with thecooking device 10. - In various examples, the
electronic device 132 can be feature-rich with respect to communication capabilities, i.e. have built-in capabilities to access the network/cloud 146 and any of the cloud-basedapplications 150 or can be loaded with, or programmed to have, such capabilities. Theelectronic device 132 can also access any part of the network/cloud 146 through industry standard wired or wireless access points, cell phone cells, or network nodes. In some examples, users can register to use theremote server 144 through theelectronic device 132, which may provide access thecooking device 10 and/or thereby allow theserver 144 to communicate directly or indirectly with thecooking device 10. In various instances, thecooking device 10 may also communicate directly, or indirectly, with theelectronic device 132 or one of the cloud-basedapplications 150 in addition to communicating with or through theserver 144. According to some examples, thecooking device 10 can be preconfigured at the time of manufacture with a communication address (e.g. a URL, an IP address, etc.) for communicating with theserver 144 and may or may not have the ability to upgrade or change or add to the preconfigured communication address. - Referring still to
FIG. 5 , when a new cloud-basedapplication 150 is developed and introduced, theserver 144 can be upgraded to be able to receive communications for the new cloud-basedapplication 150 and to translate communications between the new protocol and the protocol used by thecooking device 10. The flexibility, scalability, and upgradeability of current server technology renders the task of adding new cloud-based application protocols to theserver 144 relatively quick and easy. - Referring to
FIG. 6 , thehousing 12 of the cooking device may be coupled to asupport structure 158 that includes one ormore legs 160. Any of thelegs 160 may be operably coupled with a swivel caster and/or awheel 162 to facilitate movement of thecooking device 10. Theshelf 28 may be operably coupled with thesupport structure 158 and/or supported by one or more of thelegs 160. Thecontrol unit 56 may be operably coupled with thehopper 42, which can be supported by thehousing 12. The control unit may be electrically with thepower actuator 90. In some examples, thepower actuator 90 may be housed within thehopper 42. Likewise, the cookingdevice power supply 98 may additionally be housed within thehopper 42. As provided herein, thepower actuator 90 may receive power from one or more sources, including the cookingdevice power supply 98, theexternal power supply 102, and/or the vehicle power supply 100 (when thecooking device 10 may be electrically coupled with a vehicle 78 (FIG. 1 )). As provided herein, each source may be utilized in a predefined manner when electrically coupled with thepower actuator 90. - In some examples, when the
second branch 94 may be configured to connect with thevehicle power supply 100, and thethird branch 96 may be configured to couple with anexternal power supply 102. Either or both of thesebranches hopper 42 when not connected with respective power sources. - Referring to
FIG. 7 , in some examples, thecontroller 86 is operated by an application specific integrated circuit (ASIC) 164. TheASIC 164 may be mixed signal that contains power conditioning, RF, high voltage line driving, digital logic and an integrated 64 bit microcontroller. Application programming is executed in an ASIC along with customized peripherals for operating thecooking device 10 and the various assemblies of thecooking device 10. Thecontroller 86 may be implemented using any one of a number of commercially available microcontrollers. - Referring to
FIG. 8 , in some examples, thetransceiver 134 may also include an application specific integrated circuit (ASIC) 166 that contains power conditioning, RF, high voltage line driving, digital logic and an integrated 64 bit microcontroller. Application programming is executed in an ASIC along with customized peripherals for communicatively coupling thecooking device 10 with one or moreelectronic devices 132. In some examples, theelectronic device 132 may be configured to receive user inputs via thetouchscreen circuitry 140 on thedisplay 138. In response, the inputs may be relayed tocooking device 10 and/or thecontroller 86 through direct communication and/or through usage of the network/cloud 146. The inputs may relate to a desired power supply, in which the user may override the guidelines provided in the repository 118 (FIG. 3 ). - Referring to
FIG. 9 , thecontroller 86 may be operably coupled with one or moretemperature detection circuits 168 that may be implemented for detecting and/or monitoring various temperatures within thecooking device 10. For example, thetemperature detection circuit 168 may monitor a temperature within theheat assembly 36, theheating chamber 14, and/or the food item. In response to receiving an input from thetemperature detection circuit 168, thecontroller 86 may alter the cooking characteristics of thecooking device 10, alter the power usage of thecooking device 10, alter power usage from thevarious power sources - Referring to
FIGS. 10 and 11 , thecontroller 86 may also be operably coupled with an igniter drive circuit 170 and/or anigniter control circuit 172, which respectively drive and control theigniter 38 of the cooking device to selectively energizeigniter 38 in order to maintain ignite thefuel 40. The circuit may be a closed loop feedback circuit in which the temperature of the heating chamber is sensed and the igniter is selectively energized when the heating chamber is below a preselected temperature. - In some examples, the
igniter 38 is energized digitally such that theigniter 38 is switched ON or OFF in response to digital pulses form theigniter control circuit 172, or any other circuit within thecontroller 86. As more heat is needed to raise the temperature of theheating chamber 14 to the preselected temperature, an increased number of pulses will emerge from theigniter control circuit 172. Consequently, theigniter 38 will be turned on a greater number of times per unit time interval. This feature provides a low duty cycle for the igniter drive circuit 170. Consequently, the heat generated by the devices of thecircuits 170, 172 may be kept to a minimum as compared to a linear-type circuit in which the devices are continually in their on state. This results in a relatively low power loss in the igniter drive circuit 170 thus resulting in less heat being generated in the cooking device thereby providing more stable circuit operation. In other examples, any other practicable type of circuit may be used for activating, controlling, and/or driving the igniter. - Referring to
FIGS. 12 and 13 , apower supply circuit 174 and a reference power supply circuit 176 are respectively illustrated. In some instances, thepower supply circuit 174 may be configured as a switching power supply that employs a configuration in which an output voltage is stabilized by monitoring an output voltage, comparing the output voltage with a reference voltage generated by the reference power supply circuit 176, and performing negative feedback control of switching control in accordance with the comparison result. The reference power supply circuit 176 may generate the reference voltage that stably supplies a constant voltage to a target circuit, such as thecontroller 86, regardless of an environmental change, such as when the power source is varied between the cookingdevice power supply 98, thevehicle power supply 100, and/or theexternal power supply 102. Such a reference voltage supply circuit may be used in driving an analog circuit such as an analog-digital converter (ADC), a phase-locked loop (PLL), and a filter circuit of thecooking device 10. - The examples of the cooking device of the present disclosure may offer a variety of advantages. For instance, the power actuator provided herein may provide various ways to power the cooking device thereby realizing normal functioning of the cooking device during transportation to potentially broaden the applicable scenarios in which cooking device may be utilized. The cooking device of the present disclosure may realize low power operation through the dynamic switching of available power supplies that prolongs the service time of the cooking device power supply and expands the endurance time and service performance of the cooking device. The cooking device can directly use the vehicle power supply to meet functioning requirements without further circuit adjustment and redesign of the existing vehicle by using the same voltage and the vehicle power supply. The various power supplies that are electronically coupled with the power actuator allow for optional power paths such that the power supply of the cooking device may be switched under various working conditions. For instance, when the vehicle is parked, the vehicle power supply may be utilized if available. When the vehicle is in motion, the cooking device power supply may be utilized thereby reducing the frequency of use of the cooking device power supply, avoiding over discharge/charge of the batteries, and/or prolonging the service life of the cooking device. The cooking device may also include a transceiver that may communicate directly or through the cloud with a remote electronic device. Through the electronic device, a user may alter the operation of one or more components of the cooking device. Additionally, the electronic device may receive information from the cooking device in regards to one or more components thereof. For example, a user may monitor the available power supplies through the electronic device and/or toggle usages between power supplies.
