Definitions

  • the present invention relates to an exhaust hood, and more particularly to, an exhaust hood which is installed above a range so as to discharge foul air, such as heat, vapor, food odor, etc., produced when cooking, to the outside of a room.
  • foul air such as heat, vapor, food odor, etc.
  • a hood as air exhaustion apparatus is installed above a cooking stove, that is, a range, so as to exhaust foul air, such as heat, vapor, food odor, etc., produced when cooking food, to the outside of a room, thereby keeping the room comfortable.
  • Fig. 1 is a bottom perspective view illustrating a prior art exhaust hood
  • Fig. 2 is a side view illustrating an installation structure of the prior art exhaust hood.
  • the prior art exhaust hood 10 comprises a duct portion 11 that houses an air blower 20 therein and is secured to an indoor wall 30 and a canopy portion 12 that is installed at the bottom of the duct portion 11 at a predetermined spacing from a range 50.
  • the canopy portion 12 is formed in such a shape that is relatively wider than the duct portion 11, and has a suction port 12a formed at a lower part thereof, and the suction port 12a has a filter 13 installed thereto.
  • the air blower 20 is operated to suck foul air produced when cooking through the suction port 12a of the canopy portion 12, and discharge the sucked foul air to the outside of a room through the duct portion 11.
  • the width of the canopy portion 12 may be relatively larger than that of a cooking area, that is, an area where food is placed, in order to quickly discharge foul air produced when cooking to the outside of the room.
  • a cooking area that is, an area where food is placed
  • the width of the canopy portion 12 is larger, the kitchen space becomes narrower.
  • the width of the canopy portion should be very restricted in consideration of the kitchen space.
  • the size of the suction port formed at a lower part of the canopy portion is also restricted. This makes it hard to quickly and effectively discharge foul air produced when cooking to the outside of the room, thereby contaminating the room air.
  • the object of the present invention is to provide an exhaust hood which can quickly discharge foul air produced when cooking to the outside of a room and prepare a pleasant indoor environment by properly regulating the opening degree of a suction port located right above food being cooked without having to make the size of a canopy portion large.

  • the duct portion 110 is secured to a kitchen inner wall 30 by general engaging means, for example, bolts (not shown).
  • the top part of the duct portion 110 is connected to an exhaust duct (not shown) connecting to the outside of the room, the bottom part of the duct portion 110 is connected to the canopy portion 120, and the duct portion 110 has an air blower 111 installed therein.
  • the canopy portion 120 is constructed of a structure having a relatively larger width than the duct portion so that it can quickly suck and discharge foul air produced when cooking.
  • the spacing between the canopy portion 120 and the range 500 is maintained a proper distance, for example, generally 600 to 650 mm, so as not to make cooking inconvenient.
  • the range 500 known as a cooking stove is provided with a plurality of burner portions, for example, a first burner portion 501 and a second burner portion 502. Depending on a user's selection, either the first burner 501 or the second burner 502 can be used, or both of the first burner portion 501 and second burner portion 502 can be used.
