Application July 6, 1948, Serial No. 37,194
1 Claim.
fan motor is disposed in the air path from the kitchen area being vented to the outside or discharge end of the conduit system, thereby providing a ventilating apparatus in which moisture, grease or other inflammable matter does not accumulate on the fan or motor so that the attendant fire hazard or possibility of damage to or loss in efficiency of the fan or motor is minimized.
Second, to provide a kitchen ventilating apparatus which also serves to vent the attic space of a house, thereby aiding in reducing the temperature thereof in warm weather.
Third, to provide a ventilating apparatus which I maintains unobstructed vent for natural air currents even when the fan is not in operation.
With the above and other objects in view as may appear hereinafter, reference is directed to the accompanying drawings in which:
Figure 1 is a partial sectional, partial elevational view of my venting apparatus with adjacent portions of a house structure shown to illustrate a manner of installation.
Figure 2 is a. transverse sectional view through 22 of Figure 1.
My ventilating system includes a main conduit l which may be rectangular, square, or circular in cross section. The lower end of the main conduit communicates with the kitchen area, preferably through the ceiling 2. The main conduit projects through the roof 3. An extension 4 extends coaxially from the main conduit to a suitable height above the roof. The extension 4 is provided with a conventional hood 5. Suitable flashing, not shown, is provided around the main conduit 1 to prevent leakage around the exterior of the conduit.
Within the attic space between the ceiling 2 and roof 3, the main conduit is provided with a lateral intake 6, which preferably tapers toward the main conduit; that is, the intake is larger at its extended end. Mounted in the extended end of the intake 6 is an electric motor 1 which drives a fan 8 positioned midway in the intake 6. The main conduit is provided with a partition member 9 which extends from the lower side of the intake 6 and curves upwardly and then continues substantially axially. It is preferred to tilt the upright portion of the partition 9 so that a Venturi throat I0 is formed in the main conduit, and a Venturi throat II is formed at the upper extremity of the partition member.
With this arrangement, air and entrained moisture, gases, grease or other matter does not come in contact with the motor or fan, but moves upwardly through the main conduit. Upward flow is induced by the air forced through the intake 6 by the fan 8, and deflected upwardly by the partition member 9. It will be noted that the main conduit may function whether or not the fan 8 is in operation. Furthermore, if the intake 6 is placed to face the prevailing draft through the attic, new will be induced through the main conduit even when the fan is not in operation. It will also be observed that in most instances the air drawn in through the lateral intake is cooler than the hot products of combustion which may be vented from the kitchen area so that there is a tendency to cool the main conduit and prevent excessive heat. On the other hand, particularly during hot weather, the draft or flow of air in the attic space is improved by operation of the fan so that there is a lowering of air temperature in the attic.
Many other embodiments of the invention may be resorted to without departing from the spirit of the invention.
I claim:
A ventilating apparatus, involving: a vertical open-ended conduit of rectilinear cross section and having a lateral opening in one wall; a partition member curving upwardly from the lower margin of said lateral opening and continuing upwardly in said conduit to divide said conduit into passages of similar cross section; the upwardly extending portion of said partition sloping toward the side of said lateral opening to form with said side a Venturi throat atits upward extremity and its lower portion forming with the opposite side of said conduit a second Venturi throat; a tubular intake funnel communicating with said lateral opening; and a fan in said intake funnel.
