An extractor hood includes a functional unit, a control unit designed to control the functional unit, a hood body, a flap pivotably fastened to the hood body, and a sensor arranged on the flap and designed to detect a state of the flap. The sensor is embodied as an acceleration sensor and connected to the control unit such that the functional unit is controlled by the control unit based on the detected state of the flap.

A cook top includes an inputter configured to receive input of a user manipulation, and a cooker configured to heat a cooking device placed on the cook top. A communicator is configured to perform communication with a user terminal device and a range hood. A processor is configured to: control an operating state of the cooker according to the user manipulation, transmit a signal for controlling an operating state of the range hood to correspond to the operating state of the cooker to the range hood, and control the communicator to transmit state information of the cook top that includes information of the operating state of the cooker to the user terminal device.

A method of controlling an electrical household system, comprises: starting a pyrolysis process in an oven, wherein the oven is connected or configured to be connected in signal communication to a household range hood; starting a suction device of the household range hood as a function of a communication signal from the oven, wherein said signal is correlated to the pyrolysis process in the oven.

A hood system including a main body comprising an exhaust duct, a fan configured to generate airflow in the exhaust duct, an arm including an intake port and configured to allow air to be sucked into the intake port so as to pass through the arm and thereafter in the exhaust duct, a driving unit configured to be driven to move the arm, a sensor module configured to sense an environmental state of the hood system, and at least one processor configured to control driving of the driving unit based on the sensed environmental state to move the arm and thereby position the intake port based on the sensed environmental state.

Systems and methods optimize energy savings associated with a kitchen hood system. Embodiments of the present invention relate to adequately exhausting a gaseous substance while minimizing the devotion of unnecessary energy. An identification module identifies a plurality of parameters associated with the kitchen hood system. Each parameter has an impact on the overall efficiency of the kitchen hood system. A weighting module weights each parameter. A weight associated with each parameter is representative of a predicted impact each parameter has on the overall efficiency that the kitchen hood system operates relative to each other parameter. An incorporation module incorporates the weight of each parameter into a reduction factor. The reduction factor is representative of an overall impact that the plurality of parameters has on the overall efficiency that the kitchen hood system operates.

An induction cooktop includes: a cover plate with at least one cooking point; a holding plate; at least one inductive heating coil arranged between the cover plate and the holding plate; at least one electronics housing fastened to a side of the holding plate facing away from the at least one inductive heating coil and having electronics for the at least one inductive heating coil; and a lower box closing off the induction cooktop at a bottom of the induction cooktop, the lower box being open at a top thereof. The at least one electronics housing is arranged in the lower box. The holding plate covers the lower box at the top. The retaining plate is connected in a force-transmitting manner to the lower box in an assembly state of the induction cooktop.

A household device, in particular a refrigeration device, includes an electronic control device configured to control at least one function of the household device, an input device connected to the control device, having at least one input and being configured to supply an assigned control signal to the control device, based on a manual actuation of the at least one input. An input locking device, in its locked state, is configured to prevent controlling of the function of the household device, despite the at least one input being actuated, and in its unlocked state, is configured to permit controlling of the function of the household device when the at least one input is actuated. The input locking device is configured and/or constructed for shifting the input locking device into the locked state, after the at least one input has not been actuated over a predefined time period.

Overhead support structure is provided for mounting above a surface. The overhead support structure supports at least one projector for projecting an image onto a surface above which the overhead support structure is mounted, in use. At least sensor is provided to sense such a surface. The at least one image projector is arranged to project an image onto a region selected according to an output of the at least one sensor. The at least one sensor may be arranged to sense the location of an object on such a surface and the at least one projector is configurable to project an image onto a region selected according to a sensed location of one or more objects on such a surface. The selected region may be changed according to a change in the sensed location of one or more objects on such a surface.

Provided are a signal processing device, a program, a range hood device, and a selection method for frequency bins in a signal processing device with which it is possible to reduce the load on computation processing for computing filter coefficients and provide an excellent muting effect even when there are a peak band and a notch band in transmission characteristics from a speaker to an error microphone. A parameter setter sets an update parameter μ such that a filter coefficient W is corrected, only for a first frequency bin that corresponds to a frequency band of a first noise and a second frequency bin that corresponds to a frequency band of a second noise.

Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described.
