4 Claims. (Cl. 99-421) This invention relates to outdoor grills and relates more particularly to a novel blower unit for accelerating the burning of the fuel, such as charcoal, after the same has been suitably ignited in order that the charcoal may be prepared for cooking in a relatively short time and without the danger attendant upon using gasoline or other explosive fluids for increasing the rate of combustion.
An important object of the present invention is to provide a blower unit which is driven by the motor used for driving a constantly rotating spit, the blower being used to direct a stream of air on the ignited charcoal mass until such time as the coals are in proper condition for broiling, after which a novel valve structure is actuated for the purpose of cutting oil the stream of air to the fire and forming a curtain of ascending air between the motor unit and the hood which encloses the fire and supports the rotating spit.
In the drawing:
Fig. l is a central section taken through a blower unit embodying the present invention.
Fig. 2 is a broken front elevation of an outdoor grill equipped with the blower unit of the present invention.
Fig. 3 is a section taken on line 3-3 of Fig. 1 and showing a front elevation of the air impeller housing and air outlet duct.
Fig. 4 is a section taken on line 44 of Fig. 1 and showing a broken front elevation of the closure plate for the housing enclosing the motor and blower unit and showing the valve mechanism in one position.
Fig. 5 is similar to Fig. 4 but shows the parts in a second position.
Fig. 6 is a broken section taken on line 66 of Fig. 5.
A common type of charcoal grill is shown in Fig. 2 which includes a fire bowl 10 supported by legs 11 and containing the mass 12 of charcoal or other fuel. A sheet metal hood 13 forms a housing for the grill and this housing provides a bearing (not shown) for one end, i.e., the lefthand end, of a rotating spit 14 on which a roast, shown at 15, may be mounted. The spit has a noncircular end portion 16 which is received within a motor driven socket 17 so shaped as to form a driving connection with the spit.
The motor driven blower unit of the present invention is enclosed within a housing 20 formed with a con tinuous side wall 21 and provided with a removable closure plate 22. Means for mounting the unit on the hood may comprise a mounting bracket 23 secured to the closure plate which is received on a complemental fixture (not shown) secured to the hood. The bracket has opposed vertical trackways 24 which receive appropriate portions of the fixture.
The mechanism includes an electric motor 25 having a drive shaft 26 which passes into a housing 34 for a speed reducing unit 31 and the driving socket 17 is mounted on the final shaft (not shown) of the gear train. A rotary impeller 32 is also mounted on the motor shaft, the impeller being mounted within a housing formed in two sections 33 and 34, the latter of which is associated with housing for the reducing gears and may be integral therewith. The other housing section 33 has an air intake opening 35 which faces closure plate 22. As indicated in Fig. 3, the impeller is mounted eccentrically of the circular portion of housing 33 and the two sections are shaped to provide an air outlet duct 36 having an annular recess 49 received within an opening 4 1 in closure plate 22. The housing is provided with air intake openings 42 and cool air from the outside of the housing is drawn in through said opening, past the motor and reduction gears and into the impeller housing.
The valve structure. includes a generally circular valve plate 44 having a side extension 45 for a pivotal support 46, for a valve member 47. The plate may be cast in a single piece including a plurality of bosses 51 on its inner face which are used for mounting the plate in spaced relation to closure plate 22 and units 52 pass through the bosses and into the closure plate. The valve plate has an opening 53 which is aligned with opening 41 in the closure plate (Fig. 6). Finally the valve plate has a number of arcuately arranged mounting studs 54 with undercut recesses 55 (Fig. 1) which receive and support an annular flange 56 secured at one end of a flexible conduit 57 having a restricted nozzle 60 at its opposite end. This conduit is thus removably mounted on the valve plate and passes through an opening 61 in hood 13 (Fig. 2). It is normally bent downwardly at about the angle shown in Fig. 2 to direct a jet stream of air on that portion of the charcoal mass close to the blower unit but it may be raised or swung horizontally to direct the stream on any other part of the mass.
The valve member 47 may also be cast in a single piece and includes a short duct section 62 having a flange 63 at its inner end, and a baflle plate 64, both mounted on one arm 65 of a bell crank lever, the other arm of which forms a handle 66 to manipulate the valve member. It will be noted that the bafiie lies at an acute angle to the face of closure plate 22 with its upper end disposed farther from the plate than its lower end. The baffle also has a peripheral flange 70 facing closure plate 22 and extending over substantially its lower half when the baffle is in its downward position of Fig. 5. In this position air from the housing passing through opening 41 in the closure plate 22 encounters the diagonally and outwardly inclined baflie and the air stream, instead of being conducted to the flexible duct 57 and thence to the fire, encounters the battle and is directed upwardly to form a curtain of cool air between the relatively hot hood 13 and the motor-blower housing.
The arrangement is very eflicient since the impeller, which requires a very small amount of power, is constantly rotating and the stream of air produced thereby is successively used for encouraging combustion and for cooling the motor. When the handle is manipulated from the position of Fig. 5 to the position of Fig. 4 the duct section 62 of the valve member becomes aligned with outlet port 41 and the fitting of the parts, as shown in Fig. 1, is sufiiciently close so that substantially all the air is directed to the fire.
The housing for the unit is shown as completed with an oif-on switch 66 and a utility receptacle 67.
While there have been described herein what are at present considered preferred embodiments of the invention, it will be obvious to those skilled in the art that many modifications and changes may be made therein without departing from the essence of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and that all modifications that come Within the meaning V 3 and range of equivalency of the claims are intended to be included therein.
