ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a heat control device for use with hinged hood top barbecues. More particularly, the invention relates to a device which works in conjunction with a hinged hood top barbecue to control heat venting from the barbecue by controlling the angle of the hood top with respect to the cooking base.
Barbecuing is one of the greatest American past-times. In recent years, barbecuing has extended beyond simply cooking hot dogs and hamburgers. Now, weekend chefs attempt to cook considerably more varied and elaborate foods. However, many of these cooking tasks require greater control over the cooking temperature than a typical barbecue provides.
The standard gas grill provides the user with some control over the cooking temperature by controlling the flame intensity. However, there can be a considerable time lag after raising or lowering the flame before the grill temperature adjusts.
With charcoal grills, little can be done to control the temperature, other than to rearrange the coals. Rearranging the coals generally requires that one first remove the grill, which is not typically feasible once cooking has begun.
U.S. Pat. Nos. 4,561,417 to Chen, U.S Pat. No. 5,007,403 to Chen, and U.S. Pat. No. 5,016,608 to Evans each disclose various barbecue devices with provisions for controlling the heat and/or cooking time.
While these units may be suitable for the particular purpose employed, or for general use, they would not be as suitable for the purposes of the present invention as disclosed hereafter.
SUMMARY OF THE INVENTION
It is an object of the invention to produce a heat control device, capable of easily controlling the cooking temperature of a barbecue. Accordingly, the device operates by controlling the size of an opening between the hood top and cooking base, and thereby controlling heat flow through said opening.
It is another object of the invention to provide a heat control device which is particularly well suited for use with a hinged hood top barbecue. Accordingly, the device operates by sliding toward and away from the hinge to vary the angle between the hood top and base and thereby vary the size of the opening.
It is a further object of the invention that the heat control device is readily adaptable to be used with any existing barbecue. Accordingly, the control device easily clamps onto the rim of the cooking base of any existing barbecue and is adjustable in height and in position along the rim.
The invention is a heat control device, for use with a barbecue having a hood top and a cooking base, wherein the hood top is hingeably attached to the cooking base, comprising a main body and a clamping assembly. The main body has a hood hollow for supporting the hood top and a rim hollow for engaging the cooking base and sliding longitudinally therealong. Heat flow from the barbecue is adjusted by adjusting an angle between the hood top and cooking base, and then positioning the main body upon the cooking base in a position where it will maintain said angle. The clamping assembly is then used to fix the position of the main body on the cooking base rim.
To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.
