The connector system may include a mounting bracket to mount the microwave cooking appliance. The adaptor and/or mounting bracket may include one or more magnets to magnetically connect the adaptor with the mounting bracket. The connector system may include a sealing system.

Embodiments of substrate supports for use in microwave degas chambers are provided herein. In some embodiments, a substrate support for use in a microwave degas chamber includes a support plate having one or more support features for supporting a substrate; a susceptor comprising a plate disposed on the support plate, wherein the susceptor includes one or more openings, wherein the one or more support features extend through corresponding ones of the one or more openings; and a metal foil disposed beneath a side of the susceptor facing the support plate.

A microwave cooking appliance includes a cooking chamber delimited by a cooking chamber wall, and a microwave apparatus configured to introduce microwaves into the cooking chamber. The microwave apparatus includes a patch antenna having a planar base body and a planar emission body, which are electrically insulated from one another. The emission body is configured to cover the base body at a distance and capable of being fed with microwave energy, with the base body corresponding to a region of the cooking chamber wall.

A thermal increase system may be coupled to a containment structure for containing a load. The system includes a plurality of shelf support structures disposed within a cavity. The plurality of shelf support structures is configured to support a repositionable electrode at a plurality of positions within the cavity. The system includes a first electrode disposed at a first surface of the containment structure, wherein the repositionable electrode is disposed within the containment structure so as to divide the cavity into separate volumes. The system includes a radio frequency signal source electrically connected to one or both of the first electrode and the repositionable electrode. The radio frequency signal source is configured to provide radio frequency energy to either or both of the first electrode and the repositionable electrode.

Various blanks are provided for forming sleeves, containers, and other constructs for heating, browning, and/or crisping of a food item in a microwave oven, and for holding and/or transporting the food item after heating. The various blanks, sleeves, containers, and other constructs may include a removable portion defined by one or more lines of disruption that enable the removable portion to be separated from the remainder of the blank, sleeve, container, or other construct.

A heating cooker according to the present disclosure includes a heating chamber, a heating unit, a capturing unit, a control unit, an appearance characteristic analysis unit that analyzes an appearance characteristic of a heated material, an information reading unit that reads heating control information, an information storage unit in which an acceptable range of the heating control information is registered, and an information determination unit that determines whether the heating control information read by the information reading unit is within the acceptable range. When the heating control information read by the information reading unit is within the acceptable range, the control unit executes heating control based on the heating control information read by the information reading unit. When the heating control information read by the information reading unit is not within the acceptable range, the control unit does not execute heating control based on the heating control information read by the information reading unit.

A door for a household microwave appliance includes a perforated electrically conductive lattice configured to cover a viewing opening of the door and having a plurality of microholes arranged in a regular pattern. The microholes have a rectangular basic shape with rounded corners.

A microwave hood system is provided. The microwave hood system includes a microwave oven enclosure defining a cooking cavity therein. A cooking component is positioned within the cooking cavity and configured to emit microwaves. The heating system defines a heating cavity therein, wherein the heating system is coupled to the microwave oven enclosure. A heating element is positioned in the heating cavity. The heating cavity reaches a temperature in a range from about 40° C. to about 80° C. when the heating element is in use. A broiler element is positioned within the heating cavity. The heating cavity reaches a temperature in a range from about hundred and 150° C. to about 300° C. when the broiler element is in use. A dual hood system is also coupled to the microwave hood system.
