| 454067000 | Having canopy exhaust hood | 9 |
| 20090042500 | Hood and pollution control unit with ultra violet light and electro-static precipitator - A ventilator assembly for removing contaminants in cooking exhaust includes a hood portion having a hood plenum and an exhaust portion downstream of and in fluid communication with the hood plenum. An electro-static precipitator is disposed in the hood plenum or the exhaust portion, and at least one ultra-violet lamp is disposed upstream of the electro-static precipitator for cleaning the electro-static precipitator. The ultra-violet radiation reacts with the cooking exhaust and removes collected contaminants from an electro-static cell of the electro-static precipitator. | 02-12-2009 |
| 20100056034 | Smoker's Enclosure - A coin operated smoker's enclosure in the form of an upright booth with polycarbonate walls, aluminum framing and a hinged door. An air recirculation system provides treated air within the enclosure as well as carbon monoxide and smoke detection. An air exhaust system filters the air for particulate matter before exhausting it from the enclosure. The coin acceptor is wired to turn on the various electrically powered devices only when the appropriate coin requirements are met. An upright compartment in one corner of the enclosure houses all of the active components and is accessible from the outside of the enclosure. | 03-04-2010 |
| 20110086587 | INDOOR GRILLING CABINET - An indoor grilling cabinet has a metal cabinet with at least one door opening to an interior portion. The cabinet is double walled with a plurality of openings in the interior wall to allow fresh air from outside to be drawn into the cabinet and exhausted through an exhaust hood disposed on top of the cabinet. A double walled exhaust pipe is provided to allow fresh air in to the air space between the double walled cabinet and to exhaust contaminated air to the outside. In one embodiment, a shelf is provided to allow a user to place a table-top grill in the cabinet. The exhaust pipe fits within an opening made in the structure or through a window with an optional window kit. An exhaust fan is disposed within the exhaust hood to draw the contaminated air out of the cabinet. In one embodiment, a light is provided. | 04-14-2011 |
| 20110275301 | Autonomous Ventilation System - An autonomous ventilation system includes a variable-speed exhaust fan, a controller, an exhaust hood, and an infrared radiation (“IR”) sensor. The exhaust fan removes air contaminants from an area. The controller is coupled to the exhaust fan and adjusts the speed of the exhaust fan. The exhaust hood is coupled to the exhaust fan and directs air contaminants to the exhaust fan. The IR sensor is coupled to the controller, detects changes in IR index in a zone below the exhaust hood, and communicates information relating to detected changes in IR index to the controller. The controller adjusts the speed of the exhaust fan in response to information relating to detected changes in IR index. The autonomous ventilation system also includes an alignment laser to indicate a point at which the IR sensor is aimed and a field-of-view (“FOV”) indicator to illuminate the zone in which the IR sensor detects changes in IR index. | 11-10-2011 |
| 20120122386 | METHOD FOR CONTROLLING AN EXTRACTOR HOOD - In a method for controlling an extractor hood, the power draw of a fan of the extractor hood is regulated as a function of the operating status of a heating system and/or air conditioning system. The power draw of the fan is reduced when the heating system and/or air conditioning system heats or cools the room in which the extractor hood is located. The power draw of the fan can additionally be regulated as a function of a signal relating to the current status of a power supply network. | 05-17-2012 |
| 20130122795 | WELDING FUME EXTRACTOR - A fume extraction hood is designed to be positioned above a welding, cutting, or other metal-working location and to remove hot gases, smoke and fumes produced during these processes. The hood forms a box-like structure with an extractor rail structure disposed in an internal volume of the hood. The extractor rail structure comprises panels that force sharp turns in the gases, causing particulate matter to drop out of the gases both outside and inside the extractor rail. A primary path for gases accelerates and re-directs the gases entering into the extractor rail, and within the rail. The rail may form a dropout tray that can be removed for cleanout of collected particulate. The side and end rails of the hood may create a secondary path for gas not directly intaken into the extractor rail. This secondary path is re-directed towards the extractor rail, where gas is collected and particulate is forced to drop out as it joins the primary path. | 05-16-2013 |
| 20130149949 | CONTROL OF EXHAUST SYSTEMS - 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. | 06-13-2013 |
| 20140187136 | EXHAUST FAN ASSEMBLY - An exhaust fan assembly is provided for expelling contaminated air from a building. The assembly includes a plenum, a fan assembly attached to the plenum, and a windband mounted on top of the fan assembly. The fan assembly is constructed of cylindrical outer and inner walls which define a bearing chamber and surrounding annular space. A fan driven by a shaft extending downward from the bearing chamber draws exhaust air from the plenum and blows it up through the annular space to a nozzle at the top of the fan assembly. | 07-03-2014 |
| 20150140913 | MODULAR SERVICES SUPPLY ARRANGEMENT - Systems, devices and methods provide energy recover, modular systems to build and revise commercial kitchen services, closed circuit exhaust, and high efficiency capture and containment of fumes from cooking processes. | 05-21-2015 |
