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.

A faux fireplace having synchronized lighting. The faux fireplace includes a firebox having a video display generating a colored faux flame at the back of the firebox, a faux ember bed with lighting having user selectable colors along a bottom of the firebox and in front of the video display, and down-lighting generating user selectable colors. A user input allows a user to synchronize the colors of the faux flame, the faux ember bed lighting, and the down-lighting in a setting. The user input allows the user to save a plurality of settings such that the controller generates the synchronized colors upon a single user touch. The firebox has a shallow depth such that it can be mounted in many settings, such as on the ground or inserted in a wall.

The present disclosure is directed to systems and methods for providing an electrically operated fireplace that includes a one or more display panels, one or more reflective surfaces inclined at an angle with respect to the one or more display panels to reflect the video images of a flame displayed by the one or more display panels. One or more filters or privacy screens are disposed proximate the one or more display panels. Beneficially, the electrically operated fireplaces disclosed herein do not require the use of moving parts, such as a rotating mirror, to provide the images of the flames. Further, since video images are used to provide the flame effect, the flame effect may be varied simply by loading a new video image into the memory portion of the control circuitry used to provide the flame display.

A PEF cooking appliance includes a container for food to be cooked. The container includes two PEF electrodes which are spaced apart from one another and between which food to be cooked can be poured. A power factor correction filter is connected to a supply voltage and configured to generate a pulse voltage greater than 600 V, and an energy storage apparatus is connected to the power factor correction filter. Connected to energy storage apparatus are wo pulse forming apparatuses such that a first one of the two pulse forming apparatuses is connected to a first one of the two PEF electrodes and a second one of the pulse forming apparatuses is connected to a second one of the two PEF electrodes.

A heater structure includes a heating unit, a power supply holder, a second conducting element, a locking component, a docking component, a printed circuit board and an identification circuit. The heating unit includes a heating container, a first conducting element and a locking component. The power supply holder has a housing. The housing is connected with an extending wall. The housing is cooperated with the extending wall to define an inner space for accommodating the heating unit. A peripheral wall of the housing is recessed downward and sideward to form a locking groove. The second conducting element is mounted in the inner space. The second conducting element is connected with the first conducting element. The locking component is locked in the locking groove. The docking component is disposed in the inner space. The printed circuit board is mounted to a bottom of the power supply holder.

An electric fireplace (10) includes a fireplace housing (12) and an electrical insert (40). The fireplace housing (12) includes a base panel (30) having a base opening (230A), a back panel (32), and at least one side panel (34). The electrical insert (40) is sized and shaped to fit and be supported and retained within the base opening (230A). Additionally, the electrical insert (40) can include a heater (26), and a controller (28) including a processor that is configured to control operation of the electric fireplace (10). Further, each of the base panel (30), the back panel (32) and the at least one side panel (34) can be manufactured and installed independently of one another. The fireplace housing (12) can further include a front frame (236) that is manufactured and installed independently of each of the base panel (30), the back panel (32) and the at least one side panel (34). Still further, at least one of the back panel (32) and the at least one side panel (34) can be foldable.

An electric fire apparatus (10)is provided, having an improved simulated fire effect. The electric fire apparatus (10)comprising a bed base (14a)which is at least in part light-transmissible. The electric fire apparatus (10)also has a holographic mesh element (18)as herein before defined which divides the bed base (14a)into a front bed base portion (42a)and a rear bed base portion (42b). At least one light source (50)is provided for directing light through the front and/or rear bed base portions(42a,42b).

A cooking apparatus comprises a cooking chamber in which a food is cooked and opened in a first direction, a heater arranged at a side of the cooking chamber and configured to provide heat into the cooking chamber, a magnetron configured to generate a high frequency supplied into the cooking chamber, and a folding shelf detachably mounted in the cooking chamber and configured to be foldable. The folding shelf extends in a second direction to support the food at a first mounting position, and while the folding shelf is in a folded state, the folding shelf configured to divide the cooking chamber into a plurality of cooking spaces at a second mounting position.

A cooking equipment running method and device are provided, and relate to the technical field of terminals. The method includes: a current running mode is acquired if it is detected that a water level of cooking equipment exceeds a preset water level during a running process of the cooking equipment; a target running mode is determined according to the current running mode, heating power in the target running mode being less than heating power in the current running mode; and the current running mode is switched to the target running mode.

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.
