Definitions

  • the present invention relates to an exhaust hood, and, more particularly, to an exhaust hood that allows flow of air to be changed based on the user's circumstances for selectively accomplishing air-curtain effect and Coanda effect, whereby the convenience of the exhaust hood is improved.
  • US-A-6 336 451 discloses an exhaust hood comprising the features of the preamble of claim 1.
  • FIG. 1 is a view schematically showing a conventional exhaust hood 10 for kitchens.
  • the other fan is disposed in front of the hood body of the exhaust hood for injecting air in front of the cooking table to isolate a user from the cooking table (air-curtain effect), or the hood body of the exhaust hood is modified such that the front end of the hood body is curved to cause air to flow along the curved front end of the hood body (Coanda effect). In this way, the suction force and collecting efficiency in front of the exhaust hood are improved.
  • FIG. 2 is a sectional view showing an exhaust hood for kitchens according to a preferred embodiment of the present invention
  • FIG. 3 is a view schematically illustrating air-curtain effect of the exhaust hood for kitchens according to a preferred embodiment of the present invention shown in FIG. 2
  • FIG. 4 is a view schematically illustrating Coanda effect of the exhaust hood for kitchens according to a preferred embodiment of the present invention shown in FIG. 2 .
  • the ring-shaped rod 62 is formed in a hollow shape such that the motor 74 is mounted in the ring-shaped rod 62.
  • the rotary shaft 75 of the motor 74 extends in the longitudinal direction of the ring-shaped rod 62.
  • the rollers 76 are rotatably connected to the connection members 78 formed at the lower surface of the louver 72 while extending toward the rollers 76.
  • connection members 78 are formed insertion holes, through which rotary shafts 77 of the rollers 76 are inserted, respectively.
  • the number of rotations of the auxiliary fan can be changed such that the number of rotations of the auxiliary fan is increased to increase the speed of the nozzle unit for accomplishing the air-curtain effect, and the number of rotations of the auxiliary fan is decreased to decrease the speed of the nozzle unit for accomplishing the Coanda effect. Consequently, the present invention has the effect of more efficiently accomplishing the air-curtain effect and the Coanda effect.
