Application April 11, 1955, Serial No. 500,614

4 Claims. (Cl. 98115) This invention has to do with ventilating equipment in which a motor-driven blower or fan is used to circulate air and particularly with such equipment as is commonly installed in kitchens over a stove and other places to remove air from the room.

An object of the invention is to provide a novel and improved ventilating apparatus particularly designed for installation in a kitchen over a stove but useful in other places embodying one or more motor-driven blowers in a compact housing provided with air filters and with the housing and motor-blower unit mounted in a hood in such a manner that all parts of the device are readily accessible and in which certain parts can be readily removed for cleaning or repair.

It is a particular object of the invention to provide a neat-appearing, easily installed, motor-driven ventilating means which embodies novel encasement means for the motor-blower unit mounted in such a manner that it may be readily swung down to provide access to the blower unit and embodying air filters which are readily removable when the encasement means is swung down.

A further object is to provide, in ventilating means of the type indicated, a motor-blower unit which is detachably mounted on a portion of the hood and which under normal conditions, is enclosed by a housing which can be opened to permit removal of the motor-blower unit.

Another object is to provide safety means in a device of the type indicated of a nature such that when the housing is opened to give access to the interior thereof, a master switch is thereby actuated to break the circuit to the motor-blower unit and to any other electrical elements within or a part of the housing.

These and other objects will be apparent from the drawings and the following description. Referring to the drawings which are illustrative of a preferred form of the invention:

Fig. 1 is a front elevational view of ventilating means embodying the invention, installed against a wall over a stove;

Fig. 2 is a sectional view on line 22 of Fig. l, but on a larger scale;

Fig. 3 is a view similar to Fig. 2, but showing the housing in open position;

Fig. 4 is a sectional view on line 44 of Fig. 2 but on a larger scale;

Fig. 5 is an enlarged sectional view on line 5-5 of Fig. 3;

Fig. 6 is a sectional view on line 6-6 of Fig. 3, on a larger scale;

Fig. 7 is a sectional plan view on line 77 of Fig. I;

Fig. 8 is a sectional view on line 8-8 of Fig. 7;

Fig. 9 is a perspective view of the motor-blower unit; and

Fig. 10 is a perspective view of a filter.

More particularly describing the invention, in Fig. 1 we show a wall 11 which may be assumed to be a building wall immediately behind a cooking stove 12. Mounted on the wall is the ventilating means of the in- K 2,828,633 1C6 Patented Ap 1958 vention which is generally indicated by numeral 14. The ventilating means comprises generally a hood 15, a motorblower unit 16 and a housing 18 which, with the hood, serves to enclose the motor-blower unit.

Although the hood 15 may be of any desired design, we show a hood which embodies a rear panel 20 which lies flush against the wall 11 and can be attached thereto by any conventional means. The hood also includes an upper wall, designated 21, which extends forwardly into the room from panel 20, substantiallynormal thereto. The hood may also have an apron or depending front wall 22 and end walls 23.

The motor-blower unit 16 is removably mounted in the following manner. The wall 21 is provided with an air outlet opening 25 in which is mounted a vent stack fitting 26 which includes the channel-shaped portions 27 at two opposite sides disposed below the wall 21 of the hood. The portions 27 act as a guide or track for receiving laterally extending flanges 28 at two opposite sides of the outlet portion 29 of the motor-blower unit 16. The fitting 26 may be spot-welded to wall 21, or otherwise secured. It will be apparent that with this construction the motor-blower unit is detachably mounted and can be removed merely by sliding it forward as indicated in Fig. 3 where it has been shown in broken lines after removal from the track.

The housing 18, which with the hood 15 serves to enclose the motor-blower unit, includes a lower wall 31, a front wall 32. and two end frames 34 which are connected by the aforementioned walls 31 and 32. The front wall 32 has an inwardly projecting flange 32' at its upper margin and this may be covered with a felt or resilient strip 35 to make sealing engagement with wall 21 of the hood. A curved translucent panel 36 fills the space between the forward margin of the lower or bottom wall 31 of the casing and the front wall 32. This may -be of glass or plastics.

The housing wall 32 supports an electrical terminal and switch box 38 and depending from this is a tube 39 through which wires may extend to a double socket lamp fixture 40.

The end members or frames 34 of the housing are substantially rectangular and each provides a relatively large aperture 34a for the inlet of air to the motor-blower unit. Each end frame has an upright channel member 41 at the front and a second channel member 42 at the back which are disposed facing each other to accommodate a filter panel or screen 43. The filter panel may comprise a frame 44 of metal or the like and filter material 45 within the frame. The latter may be several sheets of expanded metal, metal mesh, Fiberglas or other material commonly used for the purpose. The filter panels 43 are removably mounted and are merely slid into place to cover the openings 34a. Base channel members 46 are mounted above the bottom wall 31 to limit the downward movement of the filters in the frames. The upper edge of each filter panel is in the same plane as the upper surface of flange 32' on the front wall and may be covered with a strip 47 of felt or other material for abutment with Wall 21 of the hood.

For the purpose of releasably securing the housing 18 in position to enclose the motor-blower unit, we provide a slotted, laterally projecting bracket 49 on each end frame at the top and near the front thereof for engagement by a securing means in the form of an L-shaped bolt 50, one leg of which is pivotally mounted in a bracket 51 secured to the wall 21 of the hood. The other leg of the bolt depends and carries a knurled nut 53.

With the construction above described, it will be apparent that the housing 18 may be securely but releasably fastened in place in the position it occupies in Figs. 1 and 2 of the drawing thereby to enclose the motor-blower unit and when in this position the air which reaches the motorblower unit must pass through filter panels 43. It will also be apparent that by releasing the nuts 53 and bolts 50 from the brackets 49 on the casing, the housing may be swung downwardly to the position it occupies in Fig. 3 thereby giving access to the interior of the'housing and to the motor blower unit. As previously pointed out, the motor-blower unit may be removed if desired. Also, with the housing in its lower or open position, the filter panels 43 may be readily slid out from the end frames of the casing as has been indicated in Fig. 3.

As a safety feature we mount a master switch against the rear panel 2% with a depending button 56. This switch is wired in series with the source of electrical current on the one hand and the motor-blower unit and lamp sockets on the other hand so that it is necessary that the switch be closed for these elements to function. The button 56 closes the switch when it is pushed upwardly by a shelf or bracket 53 carried by a cross frame element 59 at the rear of the casing. Thus, when the casing is closed as in Fig. 2 the switch 55 is closed and the various electrical units can function. However, when the casing is opened the switch 55 thereby opens and no current passes to the lamp sockets or motor-blower unit.

Although we have illustrated and described a preferred form of our invention, we contemplate that various changes and modifications can be made therein without departing from the invention, the scope of which is indicated by the following claims.

We claim:
