A method of operating a heating device includes heating air in a heating device chamber. The method further includes exhausting outgoing air from the heating device chamber via a first flow path through which the outgoing air flows in a first direction, and supplying incoming air to the heating device chamber via a second flow path through which the incoming air flows in a second direction opposite to the first direction. The latent heat in the outgoing air in the first flow path is transferred to the incoming air in the second flow path thereby condensing water vapor contained in the outgoing air to produce liquid water.

An electric heater includes a substrate, an outer pattern part disposed on one surface of the substrate, an inner pattern part disposed on the one surface of the substrate so as to be located such that the outer pattern part surrounds the inner pattern part, and to be spaced apart from the outer pattern part. A pair of first electrodes is connected to the outer pattern part and a pair of second electrodes is connected to the inner pattern part and spaced apart from the pair of first electrodes, and the pair of second electrodes are located inside the outer pattern part.

An oven appliance may include a cabinet, a plurality of chamber walls, a cooking surface, a top heating element, a temperature sensor, and a controller. The cooking surface may be defined in a cooking chamber. The top heating element may be mounted above the cooking surface to heat the cooking chamber. The temperature sensor may be disposed within the cabinet. The controller may be configured to initiate a cooking operation that includes initiating preheat activation of the top heating element, receiving temperature signals from the temperature sensor during the preheat activation, determining a preheat threshold is met based on the received temperature signals, and initiating cooking activation of the top heating element based on a cooking cycle having a predetermined time interval subsequent to determining the preheat threshold is met. Initiating cooking activation may include directing the top heating element based on the cooking cycle for the predetermined time interval.

A cooking appliance includes a cooking chamber that defines an oven cavity and a reservoir for holding water that is accessible from within the oven cavity. The cooking appliance further includes a convection heating system, a reservoir heating system, and a control system. The convection heating system includes a convection heating element and a fan for guiding air across the convection heating element. The reservoir heating system includes at least one reservoir heating element. The control system is configured to control the convection heating system and the reservoir heating system to perform a steam cooking operation in response to a user steam-cooking input.

A lighting system for an electric fireplace, and a fireplace assembly including such system, may include a plurality of logs arranged in different orientations and in different rows. Some of the logs may include a substantially planar surface facing forwards. A front projector may project a lighting effect onto the logs, including the substantially planar surfaces, and a rear projector may project a lighting effect onto a non-transparent screen positioned behind the plurality of logs. The lighting system desirably provides a realistic three-dimensional flame effect in conjunction with a log set having a natural, split-log appearance. Other features may be included to enhance the lighting system, including internal lights in the logs and in an ember bed, as well as coloration of the logs to enhance the lighting effects and the natural appearance of the logs.

Method and devices for simulating visual and audio effects of wood burning fireplace are provided. An electric fireplace includes artificial logs on a hearth area configured to simulate burning wood logs. The electric fireplace includes a mist generator to generate mist surrounding the artificial logs. At least one light engine supplies light beams to lighten the mist surrounding the artificial logs to simulate flickering fire that burns the artificial logs. The electric fireplace further includes a speaker for playing crackling wood burning sound.

A flame simulating assembly is provided with a reflected flickering light that includes only one light source. Light from the light source passes through a rotating flicker element onto one or more reflectors, or mirrors, that reflect light up onto a simulated fuel bed and the some of the light is reflected off of the flicker elements towards a flame screen to create a simulated flame. The dipping flicker elements creates a fluttering light effect due to the flicker elements “intermittently dipping” into the light path. This fluctuating light is reflected onto the logs and ember bed in front and creates a dancing effect, which simulates glowing embers.

A method includes: obtaining temperature-related information which is related to temperatures at portions of a cooking container, using a processor; recognizing an edge of the cooking container disposed in a cooking device that cooks by heating, and identifying an overheated portion in the edge where a temperature exceeds a threshold value, based on the temperature-related information using the processor; and transmitting emission instruction information to a light emitter, and causing the light emitter to emit light to the identified overheated portion.

A steaming system is for steaming food. The steaming system including a base component adapted for receiving fluid therein, the base component being adapted to cooperate with a steam generating apparatus configured to heat up said fluid to produce steam. The steaming system also includes at least one steaming component includes a steaming compartment adapted to contain food to be steamed, the at least one steaming component being operatively mounted on the base component and being in fluid communication therewith. The steaming system is operable in a steaming configuration where the components are stacked onto one another to allow circulation of steam from the base component to the steaming compartment. The steaming system is further operable in a storage configuration where the base component is contained within the steaming compartment.

An electric fireplace insert assembly includes a fireplace insert, an ember bed module and a candelabra module. The ember bed module and the candelabra module are interchangeably installed within a firebox cavity defined within the front of the fireplace insert. The candelabra module may be separately operable from the fireplace insert, providing an additional decorative display. The electric fireplace insert may further include a projector module configured to project a simulated flame onto a rear wall of the fireplace cavity. The electric fireplace insert further includes a heat/blower unit to provide space heater functionality and a flame simulation assembly.
