Definitions

• the present invention relates to a slide-type range hood, which is constructed so that a slider is mounted to a lower portion of a hood housing in such a way as to be pushed into or pulled out from the hood housing, an exhaust fan is installed in the hood housing and operated to suck odors and hot air from a room, especially a kitchen, through exhaust filters mounted to the bottom of the hood housing and the bottom of the slider, prior to discharging the odors and hot air through a backdraft exhaust damper to the atmosphere, an air supply housing having an air supply fan is mounted on the hood housing, and a front injection trough having a nozzle along the bottom thereof is mounted to the front of the slider, thus jetting exterior air, drawn by the operation of the air supply fan installed in the air supply housing, through the nozzle of the front injection trough, therefore forming an air curtain under the front of the range hood.
• Background Art
• a conventional slide-type range hood 1 includes a box-shaped hood housing 2.
• a backdraft damper 4 equipped with an exhaust fan 5 is installed in the hood housing 2, and an exhaust filter 6 is mounted to the bottom of the hood housing 2.
• Side support frames 3 are provided along opposite sides of a lower portion of the hood housing 2.
• a slider 10 is inserted through an opening 2-1 provided on the front of the hood housing 2 and supported on the side support frames 3 to be pushed into or pulled out from the hood housing 2, with a front plate 11 attached to the front of the slider 10.
• An exhaust duct 12 is defined in the slider 10 and opens rearwards, with an exhaust filter 13 mounted to the bottom of the slider 10.
• a limit switch 7 is installed at a rear position on theinner surface of either of the side support frames 3, and detects whether the slider 10 is pushed into or pulled out fromthe hood housing 2, thus controlling the operation of the exhaust fan 5.
• the exhaust fan 5 When the electricity is supplied to the exhaust fan 5, the exhaust fan 5 operates to suck air from a room. Due to the suction force of the exhaust fan 5, odors and hot air produced from a cooking apparatus, such as a gas range, are forcibly drawn into the hood housing 2 through the exhaust filters 6 and 13 that are mounted to the bottom of the hood housing 2 and the bottom ofthe slider 10, respectively. The odors and hot air, drawn through the exhaust filters 6 and 13 into the hood housing 2, are discharged through the backdraft damper 4 to the atmosphere.
• a cooking apparatus such as a gas range
• the conventional slide-type range hood 1, constructed and operated as described above, is problematic in that it merely sucks odors and hot air produced from a cooking apparatus, such as a gas range, using the suction force of the exhaust fan 5, so that it is impossible to completely suck odors, hot air, and noxious gases produced bythe cooking apparatus. Thereby, some of the odors, hot air, and noxious gases produced from the cooking apparatus may disperse into a room, thus making indoor air dirty.
• the present invention has been made keeping in mind the above problems occurring in the prior art, and the present invention aims to provide an improved slide-type range hood.
