A method for allowing opening of a first door pane with respect to a second door pane of a multi-pane door assembly of an oven appliance includes receiving, via a controller, one or more safety conditions relating to the oven appliance. The method also includes determining, via the controller, whether the one or more safety conditions correspond to one or more predetermined safety conditions. Further, the method includes allowing, via the controller, opening of the first door pane with respect to the second door pane of the multi-pane door assembly to provide access to a space between the first and second door panes only upon satisfaction of the one or more safety conditions corresponding to the one or more predetermined safety conditions.

Coated glass or glass ceramic substrates having high temperature resistance, high strength, and a low coefficient of thermal expansion. The coating includes pores, is fluid-tight and suitable for coating a temperature-resistant, high-strength glass or glass ceramic substrate with a low coefficient of thermal expansion, and to a method for producing such a coated substrate.

A cooking appliance includes a door frame that supports a heating part and is coupled to a door such that the heating part is disposed at the door.

An electric composite heat oven provided with a sight window of a transparent planar heating element is provided. Since the electric composite heat oven has a structure in which a heater heating element is installed, being lower than the upper end of a cooking container, on the front and rear sidewalls of a cooking chamber of an enclosure and a transparent planar heating element is installed over an opening of the cooking chamber of the enclosure, radiant heat may actively control various disturbances that occur during cooking depending on a place where the oven is installed and a change in temperature, whereby there is an effect of providing the optimum heat power depending on a cooking material and also shortening cooking time.

Disclosed herein is a cooking apparatus having an improved drainage structure. The cooking apparatus includes a main body having a cooking chamber with an opening provided to be opened forward, and a door coupled to the main body so as to open and close the cooking chamber. The door includes a door frame, a cover glass arranged on a front surface of the door frame, a touch panel arranged between the cover glass and the front surface of the door frame and provided to be in close contact with the front surface of the door frame by being pressed by the cover glass, and a drain hole arranged at a region, corresponding to a lower end of the touch panel, of the front surface of the door frame, and provided to allow a front surface and a rear surface of the door frame to communicate with each other.

A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem includes a housing, an agitator actuator, an agitator, a bearing and a door. The housing has an inner surface defining an inner chamber for holding a batch of beans during a thermal roasting process. The agitator is coupled to the agitator actuator and includes a central shaft and a blade set mounted to the central shaft. The bearing supports the central shaft and is configured to prevent the blade set from contacting the inner surface of the housing. The door has a transparent window to allow viewing of the thermal roasting process. The air handling system is coupled to the roasting subsystem, includes a blower and heater, and is configured to circulate heated air through the roasting subsystem during the thermal roasting process.

The present invention provides a panel assembly, a refrigerator, and home appliances. The panel assembly of the present invention comprises: a first panel formed of a glass material; a second panel spaced apart from the first panel and formed of a glass material; a plurality of spacers provided between the first panel and the second panel so as to maintain a gap between the first panel and the second panel, and arranged to be spaced apart from each other; a sealing member disposed between the first panel and the second panel for sealing a space between the first panel and the second panel; an exhaust hole provided in at least one of the first panel and the second panel so as to discharge air such that the space between the first panel and the second panel becomes a vacuum insulation space; and a cover member covering the exhaust hole.
