Definitions

  • the present invention relates to a household extractor hood which has a functional component call the outlet connector which connects to the duct for the purpose of directing cooking fumes to be expelled out of the kitchen.
  • the outlet connector is usually of flame-proof plastic or metallic material.
  • blower system usually a centrifugal blower located in hood shield casing.
  • the blower When the blower is running, the low pressure generated in the hood shield casing generated attracts cooking fumes under hood. The cooking fumes travel past a grease condensing filter of a metallic or other suitable material. The blower then ejects the cooking fumes through the outlet connector to the duct system to be expelled out of the kitchen.
  • the object of the present invention is to create a kitchen extractor hood having the same function of expelling cooking fumes out of the kitchen without a centrifugal blower that is mounted within the hood shield casing.
  • the objective is achieved through mounting an electric motor driven propeller inside the outlet connector.
  • the propeller turns, creating a differential pressure that attracts cooking fumes into the hood shield casing.
  • the cooking fumes passes through grease filters into the hood shield casing is further forced into the duct system by the propeller. (see fig.2 )
  • the hood performs the function of expelling cooking fumes from the kitchen, eliminating the need for a centrifugal motor mounted inside the hood shield casing.
  • the propeller and the motor are located in the outlet in a position that could be higher or lower than the top panel of the hood shield casing (see fig.3 ) in order to achieve the best conditions for the particular design of hood it is equipped with.
  • the identifying feature of this novel system is the axis of the propeller & the motor spindle is inline with the tubular cross section centre point of the outlet connector. (see fig.4 )
  • the motor is operated by electricity.
  • the on or off switch and the power levels are controlled by means of a mechanical or electronic switch located on the hood itself.
  • the propeller can be made of plastic, metallic or any other suitable material.
  • H refers to hood shield casing T refers to top panel of hood shield casing
  • D refers to decorative funnel 0 refers to outlet connector
  • C refers to centrifugal motor M refers to motor & propeller F refers to aluminum filter
  • a variant of the invention will have the diameter of the propeller larger or smaller than the outlet connector.
  • the identifying feature remains that the axial of the propeller, motor spindle and center of the cross section area of the outlet connector are inline, as illustrated in FIG 4A, 4B .
