Furthermore, the third section 114 of the respective air conduit 96 is associated with the secondary end 104 of the respective air conduit 96.
Each air conduit 96 of the pair of air conduits 96 has a coupler 116 that is attached to the primary end 102. Additionally, the coupler 116 on each air conduit 96 has a diameter that is greater than a diameter of the primary end 102. The coupler 116 on the primary end 102 of a respective air conduit 96 insertably receives a respective tube 61 of the pair of tubes 61 on the upper surface 59 of the top wall 54 of the fan housing 50. In this way each air conduit 96 of the pair of air conduits 96 is in fluid communication with the fan 72. The secondary end 104 of each air conduit 96 of the pair of air conduits 96 is directed toward each other when the coupler 116 associated with each air conduit 96 of the pair of air conduits 96 insertably receives the respective tube 61. In this way the secondary end 104 of each air conduit 96 of the pair of air conduits 96 can be directed toward the food product 98.
In use, the exhaust housing 12 is positioned in the support surface 22 and the exhaust housing 12 is strategically oriented to enable the secondary end 104 of each air conduit 96 to be directed toward the food product 98. The power cord 88 is plugged into the power port 86 and the power button 92 is depressed to turn on the motor 74 thereby urging air into each of the pair of air conduits 96. In this way the odors and irritants produced by the food product 98 are drawn into the air conduits 96 and are filtered from the air by the air filter 38. Thus, the user 100 can process the food product 98 without having to endure unpleasant odors or irritants produced by the food product 98. The air filter 38 can be removed from the exhaust housing 12 to enable the air filter 38 to either be replaced or to enable the air filter 38 to be cleaned.
