Definitions

  • the present invention relates to an exhaust hood, and particularly, to an exhaust hood having an improved efficiency for collecting contaminated air.
  • an exhaust hood is disposed above a cooker such as a gas range or a laboratory table that generate materials causing air pollution like smoke, smells and grease vapor.
  • FIG 1 is a side sectional view that illustrates one example of an exhaust hood according to the conventional art.
  • the conventional exhaust hood includes a canopy 21 installed above a cooker 10 having a plurality of burners 11a and 11b spaced at a predetermined distance therebetween, and an exhaust part 31 communicating with the canopy 21 and upwardly protruding from the canopy 21 to a predetermined height.
  • An inlet 23 is formed at the bottom of the canopy 21, through which the polluted air including pollutants like smoke, smells and grease vapor generated from the cooker 10 is drawn in. Also, a grease filter 24 that can collect pollutants is mounted at the inlet 23.
  • An exhaust path 33 is formed in the exhaust part 31, through which the polluted air having been introduced through the inlet 23 is exhausted to the outside.
  • An exhaust fan 34 for forcibly taking in the air is installed under the exhaust path 33.
  • the polluted air including smoke, smells and grease vapor generated as burners 11a and 11b of the cooker heat food items is in a buoyancy jet form and increases in width as it ascends.
  • a method of increasing a rotation rate of the exhaust fan 34 and thusly increasing an intake force may be used.
  • the rotation rate of the exhaust fan 34 is increased to increase the intake force, the intake performance is not improved in proportion to the increased rotation force. For this reason, only the intake force of the exhaust fan 34 used in such a method is not enough to guide the polluted air, which is moved to outside along the bottom surface of the canopy 21, to the inlet 23.
  • the conventional exhaust hood cannot prevent the polluted air from moving out from the canopy 21, polluting an upper region (A) of the front side of the canopy 21 and spreading to a room to thus pollute a surrounding environment.
  • FIG 2 is a side sectional view that illustrates another example of a conventional exhaust hood.
  • the conventional exhaust hood in accordance with another example includes a hood body 51 disposed above a cooker 10 at a predetermined distance therebetween, and a nozzle part 81 installed at a front region of the hood body 51 and downwardly discharging the air.
  • the hood body 51 includes a canopy 61 installed above the cooker 10, which has a plurality of burners 11a and 11b, at a predetermined distance therebetween, and an exhaust part 71 communicating with the canopy 61 and upwardly protruding from the canopy 61 to a predetermined height.
  • the nozzle part 81 is formed at a front region of a bottom surface of the canopy 61 and discharges the air downwardly.
  • An air supply fan 83 for blowing the air to the nozzle part 81 is installed in the canopy 61.
  • a curve shape portion 85 having an arc shaped section which is convex downwardly is formed at a lower side of the front surface of the canopy 61, so that a portion of the air discharged through the nozzle part 81 can flow to a region of the inlet 63 by the so-called coanda effect.
  • the curved shape portion 85 the polluted air cannot be moved outside the canopy 61 but is guided to the inlet 63.
  • the nozzle part 81 is formed at a spot inwardly spaced apart from the front end of the canopy 61 at a predetermined distance.
  • the polluted air having ascended inside the canopy 61 can be guided to the inlet 63 by the air discharged through the nozzle part 81.
  • the method does not solve the problem that the polluted air ascending to the front end of the canopy 61 is moved out from the front end of the canopy 61 and pollutes an upper region (B).

  • Fig. 7 is a sectional view taken along a line VII-VII of Fig. 6 .

  • the negative pressure region S1 extends up to the upper portion of the curved shape portion 141, but, on the other hand, the air is not moved downwardly up to the lower portion of the curved shape portion 141 but separated from the curved shape portion 141 at its middle portion. As a result, the vortex is formed, thereby decreasing the coanda effect.
  • the flow guide 170 is disposed at the lower side of the curved shape portion 141 to guide the air flow downwardly up to the lower side of the curved shape portion 141 and to restrain the vortex formation caused by the flow separation, thereby maximizing the coanda effect.

  • the air horizontally discharged through the nozzle 143 flows along the upper surface of the curved shape portion 141 to form the negative pressure region S1 having the minus (-) gauge pressure at the upper and front surfaces of the curved shape portions 141.
