4 Claims. (01. 98- 115) My invention relates to ventilators of a type used to carry away cooking odors, smoke, heat and grease-laden fumes from kitchensgas ranges and stoves used for similar purposes.

In this connection, one of the principal objects of the invention is'the provision of a ventilator of the type referred to and adaptable to any kitchen of the home or elsewhere wherever a flue and electrical service are available, and which may be installed at a minimum of cost.

Another object of the invention is the novel and simple construction of the .ventilator and wherein the exhausting unit. and the smoke deflector are capable of easy removal for thepurl5 pose of cleaning,,inspection or replacement.

Another important object of the invention is the construction and arrangement of the smoke deflector, said deflector permitting the suction of air to draw the smoke and fumes over the entire '20 area of the inside of the hood.

the invention will beclearly understood from a perusal of the following detailed description, taken in connection with the accompanying drawing, and wherein:

Figure 1 represents a perspective view in part of a gas cooking range and a ventilator and illustrating an embodiment of the invention, the ventilator hood being partly broken away,

Figure 2 is a vertical transverse sectional view through the hood in Figure 1 showing in detail the various parts of the. ventilator,

Figure 3 represents a top plan view of Figure 2 of the smoke deflector and exhaust unit, the hood not shown,

Figure 4 represents a. vertical sectional detail view of Figure 3, the view being taken on the line 4-'- '-4 thereof, and showing the exhaust unit, and

Figure 5 is a. front elevational view of the exhaust unit housing 'cover plate.

Referring moreyin detail. to the drawing, like parts being designated by like characters, 1 in'-' dicates a gas or similar cooking range of modern type, although the ventilator is adaptable .to any 45 type of cooking stove where a flue outlet and electrical service-are available. The ventilator consist's of a backboard or support 2 and a hood 3, these parts being adaptable to installation in kitchens-of new or old dwellings and apartments.-

50 and being secured to the kitchen wall by the dwelling.

Secured to the board 2 is the hood 3 with the 55 lateral panels 5, these parts being positioned above With the foregoing and other objects in view provided with the burners so as to catchanddirect the smoke and fumes into the exhaust unit.

As illustrated more clearly in Figure 2 theexhaust unit consists of a powerful centrifugal blower 6,.not merely an electric fan, so that the blower is positive in action and has a suction equal to that ,of a. large exhaust fan. This blower is quiet in action andis operated by an electric motor I through the motor shaft 8 upon which the blower is mounted.

The motor I and blower Gare enclosed in a housing consisting of a bottom wall or support I 2, secured by screws to the backboard or support 2, a rear wall l0, side walls Illa and a removable cover plate I I. The cover. plate is shown by itself in Figure,5.

The horizontal partition walls l2, l3, and vertical wall 13a and the curved por'tion l3b thus complete the closure for the blower and enable the air suction, created by the blower, and as indicated by the arrows, to flow into this closure through the opening l4 and exhaust into the flue pipe 4 through the vent l5. As shown in Figure 3, the side walls Ina are bent at rightangles to provide a flange lllb for fastening these walls to the hood 3,

A conduit pipe I! with light globe I8 and pull cord l9 provide lighting facilities and a pull cord 20 starts and stops the motor I. A bracket 2| supports the conduit on the wall III. The cover plate II includes a rounded notch 23 to receive the conduit pipe l1 and the cover plate is also apertures 24 which fasterr over the stud bolts 25, welded to the side walls Ila, and the wing nuts 26 hold the cover plate in position. Consequently the cover plate may be easily removed by taking off the wing nuts and the blower and adjacent parts cleaned, inspected, or parts replaced.

In addition to the foregoing I provide a smoke deflector with upwardly

slanting walls

21 and 28, the'upper edges of which extend on a line midway across the opening l4 in the cover plate Il,'leaving a narrow opening for smoke and fumes to pass over its edges to the blower. As shown by the arrows, Figure 2,'the smoke and grease-laden fumes are thus deflected upwardly. The smoke deflector is an important'feature of my invention and provides a means whereby the suction from the blower is spread over the entire area of the'inside of the hood. The smoke deflector is secured to the bottom wall I! by stud bolts and wing nuts ill, making it easily removable for cleaning, inspection or replacement of parts.

While I have shown and described a practical working embodiment of my invention,- it is apparent that parts'thereof may be modified, altered and chang without departing from the intent of the invention, and within the scope and 5 meaning of the appended claims.

WhatIclaim as new is: 1. A ventilator of the class described and adapted to be used with a hood, said ventilator comprising'a housing having a rearwardly projecting support, a centrifugal blower for creating air suction, and electric motor-mounted on the said projecting support for operating said blower,

walls, and a rear partition wall, said partition wall separating the motor and blower, a removable covr plate for the housing, said plate having an opening for inlet of smoke and fumes, and said top wall having an opening for exhaust of said fumes and smoke, and including a smoke deflecting ,means projecting outwardly and upwardly from the'lower part of the said housing.

. 2. A ventilator of the class described in combination with a hood, the said ventilator comprising '25 a housing having a rearwardly projecting support, a centrifugal blower in the housing, an electric motor for operating said blower mounted on the said support, a smoke deflecting means comprising an apron removably secured to the lower 30 portion of said housing and directed outwardly and upwardly, the upper edges of said apron being disposed below and inside the surface of the said hood to be used with the ventilator and providing a space for entrance of smoke and the like to be suction, an electric motor mounted on the said projecting support for operating said blower, the blower being inclosed by the housing, said housing including a bottom wall,'a top wall,-side walls, the blower being inclosed by the housing, said housing including a bottom wall, a top wall, side and a rear partition wall, said partition wall separating the motor and blower, a removable cover plate for the housing, said plate having an opening for, inlet of smoke and fumes, and said top wall having an opening for exhaust of said fumes and smoke, and a smoke deflecting means comprising an apron removably secured to the lower portion of said housing and directed outwardly and upwardly therefrom within the area of the hood, the upper edges of said apron being disposedbelow the inside surface of said hood and provi ng a space for entrance of smoke and the like to be drawn into said opening of said cover plate.

4. A ventilator of the class described and as claimed in claim 1, said housing including also a curved wall and the said curved wall being accessible by removing the said removable cover.
