A double-cavity microwave oven is disclosed that includes a first and a second cooking cavity, a moveable barrier disposed between the first and the second cavity, a first and a second magnetron, and a first and a second waveguide corresponding to the first and the second magnetron, respectively. The first cavity is electromagnetically isolated from the second cavity, and, as the barrier moves, the size of the first cavity relative to the second cavity changes. As the barrier is in a first position, the first waveguide directs microwaves from the first magnetron to the first cavity and the second waveguide directs microwaves from the second magnetron to the second cavity. As the barrier is in a second position, the first and the second waveguide direct microwaves from the first and the second magnetron to the first cavity. Various embodiments are also disclosed including additional features.

An automated microwave oven configured to autonomously determine a duration of time for heating an object based on a location of the object in a microwave cavity. The heating duration may be a function of cumulative energy estimated to be experienced by the object due to the object location, e.g., radial distance from center, under rotational motion of the rotating tray. A concentric energy visualization is provided on an interior surface of the microwave cavity, representing a function of cumulative energy experienced under rotational motion of a rotating tray about its center-line. The visualization may comprise a plurality of rings concentric about the center-line, each concentric ring representing a constant value of the function of cumulative energy, oscillating in value along the radial length of the rotating tray.

A household oven includes a cooking chamber (6), a light source mount (31), an LED light source (20) arranged on the light source mount (31) to shine light into THE cooking chamber (6), a heat sink (16), and a heat pipe (15) thermally coupling the LED light source (20) to the heat sink (16). This design allows to carry off heat from the LED light source (20).

A household appliance light, in particular a light for cooking devices like ovens, microwaves or steam cookers, the household appliance light including a LED configured as an illuminant; a light housing configured to be arranged at a wall of the household appliance; a light exit opening arranged in the light housing which is enclosed by a light permeable cover; a spacer element which is arranged between the LED and the light exit opening and which is arranged in front of a light outlet plane of the LED; and a reflection device which conducts light emitted by the LED to the cover, wherein the spacer element is a light conductor that is made from one uniform material, wherein the reflection device is a reflector which defines a reflector cavity, and wherein the light conductor is run into the reflector cavity.

Systems and methods include a cooking appliance comprising a heating element disposed within a cooking chamber and operable to selectively emit waves at any of a plurality of powers and/or peak wavelengths, a camera operable to capture an image of the cooking chamber, and a computing device operable to supply power to the heating element to vary the power and/or peak wavelength of the emitted waves and generate heat within the cooking chamber, and instruct the camera to capture the image when the heating element is emitting at a stabilized power and/or peak wavelength. The computing device is operable to generate an adjusted captured image by adjusting the captured image with respect to the stabilized power and/or peak wavelength. The computing device comprises feedback components operable to receive the adjusted captured image, extract features, and analyze the one or more features to determine an event, property, measurement and/or status.

A food treatment appliance includes a muffle having a muffle interior. Arranged outside the muffle is a light-generating facility for radiating light into the muffle interior through an opening in the muffle. A light-distributing element is arranged in the muffle interior and configured to distribute light radiating in through the opening The light-generating facility and the light-distributing element are arranged such as to define a gap there between. The food treatment appliance can be applied to cooking devices having an oven functionality and/or microwave functionality.

A heating cooker includes shooting section (201) for shooting an image inside a heating chamber that accommodates a heat-target object, and controller (200) that sets a shooting condition for shooting the image of an interior of the heating chamber and carries out an image recognition to the image. Controller (200) analyzes the image of the interior of the heating chamber, thereby recognizing a state inside the heating chamber, and then changes the shooting condition in response to the state inside the heating chamber for shooting the image. The structure discussed above allows this heating cooker (100a), which carries out the image recognition to the image of the interior of the heating chamber, to achieve a greater accuracy in the image recognition.

An optical waveguide device for guiding light emitted from a light source into an interior space of a household appliance includes an optical waveguide designed to emit light, introduced into the optical waveguide at a first end of the optical waveguide, to a second end of the optical waveguide. The optical waveguide has a cylindrical outer surface between the first end of the optical waveguide and the second end of the optical waveguide. A carrier is can be coupled directly or indirectly to the household appliance and includes an optical waveguide receptacle designed to receive the optical waveguide and to fix the optical waveguide axially and radially, said carrier connected to the optical waveguide by way of the outer surface, with the optical waveguide receptacle contacting the outer surface of the optical waveguide over a periphery of the optical waveguide.

A heating cooking apparatus includes a heating cooking chamber, a first recessed portion, and a first light source unit. The heating cooking chamber includes an opening portion opening in a predetermined direction, a back wall disposed in a direction opposite to the predetermined direction with respect to the opening portion, and a plurality of walls extending from the back wall in the predetermined direction. The first recessed portion is located in a first wall of the plurality of walls and recessed from the first wall. The first recessed portion includes a first inclined wall inclined with respect to the first wall. The first light source unit is disposed on the first inclined wall. The first light source unit emits light toward the back wall of the heating cooking chamber.

An oven may include a housing having a cooking receptacle configured to hold content therein, a heating element carried by the housing and configured to heat the content, and a proximity detector carried by the housing in the cooking receptacle and configured to detect surface movement of the content. The proximity detector may include at least one SPAD.
