A kitchen appliance, such as an oven, can include a cooking cavity where contents to be cooked are placed for cooking by a user. Typically, the user desires to monitor the progress of the contents while being cooked. Historically, ovens and other cooking appliances include doors providing access to the cooking cavity having transparent windows and a light within the cooking cavity to illuminate the contents in order to monitor the progress of the contents being cooked through the window. However, the windows on the door only provide one view of the contents to be cooked. Often times, a user will need to open the door and pull out the contents to be cooked in order to view the top or another side of the contents to be cooked that is not visible through the window. Opening the door can cause a drop in temperature of the oven and can affect cooking time and quality of the contents to be cooked.
In one aspect, the present disclosure relates to an oven comprising an oven body having a set of interior panels and a set of exterior panels that are spaced from the set of interior panels such that a channel is defined between the set of interior panels and the set of exterior panels, wherein the set of interior panels comprises an interior panel peripheral wall and an interior panel top wall that at least partially define a cooking cavity. Each interior panel of the set of interior panels has an inner surface and an outer surface. The oven further comprises an imaging device provided on the outer surface of the interior panel top wall and mounted in the channel with a field of view including at least a portion of the cooking cavity. The oven also has a fan located within the channel and generating a cooling airflow through a portion of the channel. The fan is fluidly coupled to the imaging device to direct the cooling airflow over the imaging device. The oven also comprises a damper coupled to the oven body and to the imaging device for absorbing mechanical vibrations associated with airflow generated by the fan.
In the drawings:
An oven can include a camera housed within walls of a cooking cavity with a field of view that passes through at least a portion of the cooking cavity. Contents to be cooked are located within the cooking cavity such that the camera can image the contents. A thermal management system can be provided to insulate, cool and otherwise protect the camera from the heat of the oven cavity during operation.
As illustrated in
The oven 10 can include an imaging device 40 for imaging the contents to be cooked. The imaging device 40 can be in the form of a camera 40, or any other suitable imaging device 40. A display 60 such as an LCD screen 60, can be provided on the oven 10 and can be in communication with the camera 40 where the LCD screen 60 can display images captured by the camera 40. The image output by the camera 40 can be a real-time representation of the contents being cooked to allow a user to monitor the contents using the LCD screen 60 without the need for opening the door 30. Furthermore, the oven 10 can include a user interface 62. The user interface 62 can include operational controls such as dials, lights, knobs, levers, buttons, switches, and displays enabling the user to input commands to a controller 70 to operate the oven 10 and to receive information about an operational status of the oven 10. While the LCD screen 60 and the user interface 62 are shown as separate components, it is possible that the LCD screen 60 and the user interface 62 are combined into one component.
The controller 70 can implement a heating cycle selected by the user according to any options selected by the user and provide related information to the user. The controller 70 can also include a central processing unit (CPU) 74 and an associated memory 72 where various operational procedures may be stored. One or more software applications, such as an arrangement of executable commands/instructions may be stored in the memory 72 and executed by the CPU 74 to implement the operational procedures. The controller 70 can be in communication with the camera 40 such that the images can be output by the camera 40 and input to the controller 70. The controller 70 can output the images to the display 60 or another display, such as a mobile device display in order for a user to remotely monitor the contents being cooked.
The camera 40 can also include a controller 43 that can include a CPU 46 and an associated memory 48. The controller 43 or the controller 70 can be in communication with a network 80, such as the internet. The network 80 can include wired, wireless, or a combination of wired and wireless points or nodes to connect communication paths for exchanging and transporting data. Thus, the images from the camera 40 can be sent to a mobile device via the network 80 from either controller 43 or 70. The camera 40 can be directly coupled to the controller 70 or indirectly coupled to the controller 70 via the network 80.
The camera 40 can include an image recognition algorithm 76 that can be implemented as a program in the controller 43 wherein blurry images taken by the camera 40 are detected. The image recognition algorithm 76 can also decide to discard blurry images such that the blurry images are not output by the camera 40. Furthermore, the camera 40 can include a deblurring image algorithm 78 that can also be implemented as a program in the controller 43. The deblurring image algorithm 78 can correct blurry images detected by the image recognition algorithm 76. The deblurring image algorithm 78 can also be implemented in a cloud in the network 80, wherein the network 80 can communicate output from the deblurring image algorithm 78 to the controller 70.
Turning to
A channel 22 can be defined by the space between the interior panel 18 and the exterior panel 20 and can include insulation 23 located within the channel 22. The insulation 23 can be provided to insulate the cooking cavity 32 to prevent loss of heat for more efficient cooking.
The camera 40 can be mounted within the channel 22 and can be in thermal engagement with the insulation 23 to help keep the camera 40 insulated from oven heat when in operation. The camera 40 can be embedded within the insulation 23 and can be positioned such that the camera 40 having a lens 41 has a field of view 42 directed into the cooking cavity 32 including at least a portion of the cooking cavity 32. As illustrated in
In order for the field of view 42 to pass into the cooking cavity 32, the interior panel 18 can include an aperture 44. The aperture 44 can include a clear cover, which can be in the form of glass, or any other suitable transparent material to enable the field of view 42 to pass into the cooking cavity 32 and to seal the space in the interior panel 18 formed by the aperture 44. The cover can include a single layer of glass or multiple layers of glass where the cover is disposed between the interior panel 18 and the camera 40. A single or multiple layers of glass can provide additional insulation for the camera 40 and lens 41.
Furthermore, the camera 40 can include a damper coupled with the oven body 12 to control and absorb mechanical vibrations in the oven 10. The damper can be in the form of a heat resistant rubber or foam that can be disposed around the entire camera 40 or a portion of the camera 40. Mechanical vibrations can include vibrations from a fan, such as the fan 11, or airflow within the channel 22 that comes into contact with the camera 40. In the case that the oven 10 includes a range or cook top above the oven 10, vibrations to the oven 10 can result from boiling water on the range, a user moving around pots, pans, or utensils, and the like.
