Abstract
A portable barbecue-type cooking apparatus for use in combination with a gas operated cook stove includes a housing defining a cooking chamber, the housing being defined by a bottom wall, side walls, end walls and a cover for closing the cooking chamber. Chimneys extend upwardly from the bottom wall of the housing whereby water can be placed in the heating chamber around the chimneys. A fan is rotatably mounted on each of the chimneys, so that when the housing is placed over a source of heat, the heat rising through said chimneys causes the fans to rotate for deflecting grease and other food produced liquids away from the chimneys and into the water.
Description
~U~2~U~
This invention relates to a cooking apparatus, and in particular to a portable barbeque apparatus for use with a gas operated cooking stove or other heat source apparatuses.
There has long been a need for a device for cooking fat containing foods (usually meat) over a heat source without burning the meat, and without grease from the meat dripping onto the heat source. Examples of the devices which offer solutions to the above described problem, or which otherwise have features in common with the present invention are found in Canadian Patent No. 140,932, which issued to J. Kowalski et al on June 1, 1912 and 1,072,762, which issued to B. Boswell et al on March 4, 1980, and United States Patents Nos.
3,301,172, which issued to F.A. Haro on January 3l, 1967 and 4,694,816, issued to M. Fabbro on September 22, 1987.
Many such devices only partially solve the problem of grease and other juices from the meat reaching the source of heat. The principal solution to the problem is indirect cooking, i.e. ensuring that the food being cooked is not disposed directly over the heat source, so that liquid dropping from the food does not drop onto the heat source.
Obviously, such a solution necessitates a specially designed, large volume cooker. Moreover, the devices used to solve the problem are not always particularly efficient.
An object of the present invention is to provide an alternate solution to the above problem in the form of a , relatively simple portable cooking apparatus for use with a ~U~'~.',~~'U~
gas operated cook stove. Another object of the invention is to provide such an apparatus in which the entire cooking area can be utilized.
Accordingly, the invention relates to a cooking apparatus comprising housing means defining a cooking chamber, said housing means including side wall means, bottom wall means and cover means for closing said cooking chamber;
chimney means extending upwardly from said bottom wall means for admitting heat from a source thereof to the cooking chamber, whereby water can be placed in said housing means around said chimney means; and fan means for rotatable mounting on said chimney means, whereby, when the housing means is placed over a source of heat, rising heat causes said fan means to rotate for deflecting grease and other food produced liquids away from the chimney means and into the water.
The. invention will be described in greater detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:
Figure 1 is a schematic, isometric view of a cooking apparatus in accordance with the invention from one end and the front thereof;
Figure 2 is a schematic, isometric view of the apparatus of Fig. l from the same end and the rear thereof;

A ledge 17 (Figs. 3 to 5), is provided along the interior of each of the front and rear walls 3 and 4, respectively for supporting a conventional wire grill 18. The grill 18 supports food 20 during cooking. Heat reaches the food 20 via a pair of openings defined by sleeves 22 in the bottom wall 2 of,the housing 1. The sleeves 22 are located over the burners 16 of the stove 15. .
~~u~.~~a A fan generally indicated at 23 is rotatably mounted on each sleeve 22. For such purpose a generally inverted U-shaped crossbar 25 is mounted on the sleeve 22. Loops 26 on the sides of the sleeve 22 receive the legs 27 of the.
crossbar 25. A spindle 29 defined by a spike extends upwardly from the center of the crossbar 25 for rotatably supporting the fan 23 above the sleeve 22. The fan 23 is a thin metal disc 30 with a domed central hub 31 for receiving the spindle 29. A plurality of inclined louvres 33 extend radially outwardly from the hub 31. Heat rising from the burners 16 causes the fan 23 to rotate rapidly on the spindle 29. An annular flange 34 extends downwardly from the periphery of the disc 30.
A tubular tray 36 of rectangular cross section extends outwardly from the rear wall. 4 of the housing 1 for receiving wood chips 37 (Fig. 5). A cover 38 with a handle 39 is pivotally mounted on the open outer end of the tray 36 by means of hinges 40. Smoke from the wood chips 37 enters the cooking chamber via an opening 41 (Fig. 3) in the rear wall 4 of the housing~l. The chips 37 are heated by a small separate burner 43. , Before cooking, the housing is mounted on the stove 15 with the sleeves 22 aligned with the burners 16. Water is poured into the housing 1 to a level below the top ends of the sleeves 22. When the burners 16 are started, heat rising through the chimneys defined by the sleeves 22 causes the fans ~Q~N~~o 23 to rotate. As meat on the grill 18 cooks, grease and other liquids escaping therefrom fall into the water in the housing or onto the fans 23. Because the fans 23 are rapidly rotating, the liquids are thrown into the water, and do riot fall onto the burners 16. Moreover, the rotating fans serve to distribute heat uniformly throughout the cooking chamber.
Hot grease entering the water, causes steam to rise in the housing 1 to facilitate the cooking process and preventing drying or burning of the meat. Upon completion of the cooking operation, water can be drained from the housing via a pipe 44. When smoking fish or meat, wood chips 37 are placed in the tray 36, and a burner 43 is placed thereunder. Of course, the apparatus can be used to cook and/or smoke food.
crossbar 25. A spindle 29 defined by a spike extends upwardly from the center of the crossbar 25 for rotatably supporting the fan 23 above the sleeve 22. The fan 23 is a thin metal disc 30 with a domed central hub 31 for receiving the spindle 29. A plurality of inclined louvres 33 extend radially outwardly from the hub 31. Heat rising from the burners 16 causes the fan 23 to rotate rapidly on the spindle 29. An annular flange 34 extends downwardly from the periphery of the disc 30.
A tubular tray 36 of rectangular cross section extends outwardly from the rear wall. 4 of the housing 1 for receiving wood chips 37 (Fig. 5). A cover 38 with a handle 39 is pivotally mounted on the open outer end of the tray 36 by means of hinges 40. Smoke from the wood chips 37 enters the cooking chamber via an opening 41 (Fig. 3) in the rear wall 4 of the housing~l. The chips 37 are heated by a small separate burner 43. , Before cooking, the housing is mounted on the stove 15 with the sleeves 22 aligned with the burners 16. Water is poured into the housing 1 to a level below the top ends of the sleeves 22. When the burners 16 are started, heat rising through the chimneys defined by the sleeves 22 causes the fans ~Q~N~~o 23 to rotate. As meat on the grill 18 cooks, grease and other liquids escaping therefrom fall into the water in the housing or onto the fans 23. Because the fans 23 are rapidly rotating, the liquids are thrown into the water, and do riot fall onto the burners 16. Moreover, the rotating fans serve to distribute heat uniformly throughout the cooking chamber.
Hot grease entering the water, causes steam to rise in the housing 1 to facilitate the cooking process and preventing drying or burning of the meat. Upon completion of the cooking operation, water can be drained from the housing via a pipe 44. When smoking fish or meat, wood chips 37 are placed in the tray 36, and a burner 43 is placed thereunder. Of course, the apparatus can be used to cook and/or smoke food.
