A knob structure for an electromagnetic oven includes a knob switch assembly. The knob switch assembly consists of a sleeve button, a rotary encoder, a bracket of a display screen, and a control assembly. The knob switch assembly is connected to a printed circuit board through a through hole. A guide rib is disposed around a circumference of the through hole. The display screen with a protection assembly disposed outside is integrated with the knob switch assembly. The guide rib effectively prevents water from entering inside of the electromagnetic oven, lengthens a service life of the electromagnetic oven, and facilitates cleaning. The knob switch assembly integrated with the display screen realizes miniaturization and reduces a cost. The protection assembly ensures a display effect of the display screen.

Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.

In at least another aspect, a method for calculating a humidity level in a cooking apparatus is disclosed. The method comprises heating a food load in a cooking cavity of the cooking apparatus and selectively activating a convection fan in the cooking cavity. The method further comprises monitoring a humidity signal detected by a humidity sensing apparatus in response to the activation of the convection fan. As a result of the activation of the convection fan, the method may determine an actual humidity level from a plurality of humidity levels based on a change in the humidity signal.

An electric fireplace includes a shell, where a heating component including a wind turbine and a heating element is disposed in the shell, and further includes a translucent imaging screen, where the imaging screen is vertically disposed at an upper end of the shell, a flame plate that can cast a flame shape is disposed on an upper end surface of the shell, and a light source and a light interference combination that includes a light interference barrel and a motor are disposed below the flame plate. Disposing the imaging screen externally greatly reduces the size of the shell. The present utility model is small in size, convenient in transportation, and unique in model, and can be adapted to a modern decoration style.

An electric oven broils foodstuffs with either its oven door opened or closed. The operating parameters of the oven's broiling elements are altered based on the position of the door.

An electric fireplace includes a housing, a main control board, a flame processing device, a simulated wood, a light-emitting device, a light-reflecting device, and simulated bricks. All the inner walls of an accommodating chamber of the housing are bonded with the simulated bricks to form a three-dimensional brick wall effect. The flame-shaped light projects on the simulated bricks from a gap between the rear inner wall of the accommodating chamber and the simulated wood, enabling the flame burning effect of the electric fireplace to more three-dimensional.

An electric heating apparatus (1) including an electric heater (12) and a flame simulator (2). The apparatus includes an air outlet channel (14) for expelling heated air wherein the cross-sectional area of the air outlet channel (13) increases with increased distance from the heater.

A structure covering a connection line, an electric cooking appliance including the same, and a method of assembling a cap of the electric cooking appliance includes a base plate including a through hole in a vertical direction, a cap provided below the base plate and provided with an accommodation space formed therein to accommodate a connection line placed through the through hole from an upper portion of the base plate, a coupling boss extending in a vertical direction in the cap and coupled to bottom of the base plate to couple the cap to the base plate, and a fastener inserted through the base plate from the upper portion of the base plate to couple the base plate to the coupling boss.
