A stove cabinet, a disinfection cabinet and an oven or a steam cooker are integrated in the low-carbon self-balance cooking fume purifier.

A range hood range hood according to an embodiment of the present invention is provided with a vortex fan installed on an upper portion of a kitchen range to suck and remove contaminants such as odor or smoke generated during cooking. The range hood includes a housing with an exhaust fan installed inside thereof, an upper case coupled to a lower end of the housing and guiding an airflow generated by a vortex fan, wherein a through hole connected to the exhaust fan is formed at a ceiling surface of the upper case, and a lower filter case installed spaced apart from a bottom of the vortex fan.

A cooking engagement system includes a cooktop appliance and an interactive assembly positioned above the cooktop appliance. The interactive assembly includes an image monitor that presents various images and information to a user, e.g., recipes, and a capacitive touch sensor that senses touches on an imaging surface of the image monitor. When the capacitive touch sensor senses a capacitance level below a threshold indicative of contamination on the imaging surface, a controller communicatively coupled thereto activates an air handler to move or motivate an airflow across or about the image monitor. In this way, the image monitor may be cooled and condensation is prevented from forming on the imaging surface of the image monitor.

A cooking unit includes a cooktop, a hood assembly, a duct assembly, and a fan. The cooktop defines a slot at least partially extending along a peripheral edge of the cooktop. The hood assembly includes a hood support extending upward from the cooktop and a hood coupled to the hood support. The hood support defines a conduit. The hood defines an intake and a hood chamber connecting the intake to the conduit of the hood support. The duct assembly includes ducting extending beneath the cooktop. The ducting connects the conduit to the slot. The fan is positioned to drive air into the intake, through the hood chamber, through the conduit, through the ducting, and out of the slot. At least a portion of the air exiting the slot returns to the intake such that an air curtain is generated between the slot and the intake.

Kitchen extractor hood with directional flow having a box body, an extractor fan with at least one inlet in communication with an internal chamber of the box body, a delivery fan with an inlet in communication with the internal chamber of the box body and a delivery outlet in communication with a delivery conduit, a distributor disposed at the end of the delivery conduit and deflector means disposed above the distributor in such a way to direct a delivery airflow from the delivery conduit towards at least one preferential direction with respect to the axis of the distributor, in such a way that at least two airflows with different flow rate come out from the distributor, wherein the airflow with the higher flow rate is directed towards a burner of the cooktop having a higher power than the other burners.

A ventilation system and a method for discharging hazardous air during cooking are disclosed. The ventilation system allows hazardous air generated by cooking to flow in a backward direction of a cooking device so as to quickly transfer the hazardous air to a hood, such that the hazardous air is prevented from being inhaled by a user. As a result, the hazardous air may be concentrated into a predetermined region without being dissipated, and then subsequently discharged outside. Information about a quality of air generated in a current state of a cooking space is transferred to a user so that the user may more actively use the ventilation system, thereby better protecting the user's health.

A cooktop ventilation appliance or system provides ventilation of a domestic cooking appliance, and includes a complex curve interior flow surface in the housing, the complex curve interior flow surface partitioning the interior of the housing for separately conveying secondary air and exhaust air. A first side of the complex curve interior flow surface configured to guide and smooth a flow of the secondary air from an opening for receiving secondary air into the interior of the housing to an opening for permitting the secondary air to exit the housing to form an air curtain that enhances a capture ability of the domestic ventilation appliance.

A cooktop ventilation system for providing ventilation of a domestic cooking appliance, includes a domestic ventilation appliance including housing having at least a first opening and a second opening, the first opening for capturing exhaust air from the domestic cooking appliance and the second opening for permitting secondary air to exit an interior of the housing to form an air curtain that enhances a capture ability of the domestic ventilation appliance to capture the exhaust air, and a dual direction flow blower/fan configured both to convey the exhaust air through the housing from the first opening in a first direction and to convey the secondary air through the housing to the second opening in a second direction, the second direction being opposite the first direction.

A mounting bracket mountable to the underside of the cabinet prior to the range hood and configured to engage and support the range hood as the range hood is secured to the cabinet. The mounting bracket having a support feature engagable to the range hood to hold the range hood proximate the cabinet while fasteners are sunk to secure the range hood to the cabinet. The mounting brackets are pre-positioned on the cabinet such that range hood is aligned with the cabinet when the range hood is supported by the support feature. The smaller mounting brackets can be more easily mounted in the proper position on the cabinet then the larger range 10 hood speeding the installation process and reducing errors.

An exhaust hood includes a housing, which is open towards a bottom face to capture cooking by-products from a cooking appliance positioned below the exhaust hood. The housing has a first wall and a second wall opposite to the first wall. The second wall is at least partly inclined inwardly from the bottom face towards a top face of the housing and has an exhaust vent to extract cooking by-products captured by the housing. The exhaust hood has a fresh air fan and the first wall forms a first duct which has openings located in a row along a lower edge of the first wall adjacent to the bottom face and oriented inside the housing. A side wall extension extends from one side wall and forms a lateral skirt that defines a pass-through window having vertically and horizontally extending faces. The side wall extension forms a side wall duct with openings along the vertically and horizontally extending faces that eject vertical and horizontal air streams orthogonal to one another that coalesce to form a vortex which limit cooking by-products from passing through the pass-through window.
