ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a hood device constructed and arranged to conserve energy when used in combination with a grill or counter-top stove with an exhaust by preventing the escapement of smoke and fumes while minimizing smoke, spatter and fume build up with a controllable cross ventilation system. The invention is constructed for use in combination with a grill or a counter top stove such as a JEN-AIR stove.
BACKGROUND OF THE INVENTION
In today's market, it is common place to see homes built that include a conventional downdraft cooking range.
The down-draft cooking range is a popular selling feature in today's housing market.
The cooking rage is provide with a suction exhaust which vents downwardly between adjacent cooking units. The cooking units may be electric, gas or any other well known heating source.
Today's modern kitchen usually includes an island-type cooking unit with electric or gas burners and suction means for removing smoke, grease-laden vapors, hot air and the like from the surrounding kitchen area. However, hoods or grill top lids designed for the notoriously famous JEN-AIR stove have not eliminated the release of grease-laden vapors which cause havoc by settling on luxurious ceramics, elegant hardwood floors and decorative walls and ceilings. Moreover, the release of smoke from a stove or from food under a hood on the stove has been known to trigger an alarm or smoke detector. This could turn a relaxed housewife into a nervous wreck. Additionally, in homes that are monitored at a central control station, a triggered alarm could needlessly set your municipal fire apparatus in motion.
In the prior art, the patent to Kalenian (U.S. Pat. No. 5,078,122) teaches the provision of an open-ended hood of u-shaped configuration with heat insulation means in the upper surface and below the handle member to decrease heat transfer to the handle.
The present invention is a hood with four depending sides with venting means. The venting means can be regulated to provide the maximum utilization of heat energy radiating from the heating unit or units enclosed by the hood.
The patent to White (U.S. Pat. No. 5,279,279) shows an adjustable u-shaped deflector device. The device can be adjusted in four directions. However, the device is unlike the present invention. The hood of the present invention utilizes the heat energy from a grill eye or broiler section of a counter-top stove, provided with an exhaust suction, to maximize the cooking potential of the section of the stove through the skilled manipulation of vents located in the hood.
The hood of the present invention maximizes the cooking potential of a stove section by regulating the influx of fresh air to the internal portion of the hood while the down draft of the exhaust suction opening in the stove removes smoke and various fluid contaminants entrained in the air moving through the hood to the exhaust suction opening.
BRIEF SUMMARY OF THE INVENTION
The hood of the present invention is structurally designed to solve the problems encountered by the well known counter top stove such as a JEN-AIR stove with an exhaust suction opening.
Counter top stoves with an exhaust means are normally operated without a hood or grill top lid. This type of open cooking has several drawbacks when operated in an enclosed environment such as the kitchen area of a modern house. Moreover, the scarcity of energy sources has taught us to be resourceful and to conserve energy that is used. The conservation of energy for economic reasons is equally applicable in this case. That is, due to the constant increase in the cost of energy, one is lead to devise means to conserve energy.
It is well known to provide a gas or electric counter top stove with a hood arranged in combination with a suction or exhaust opening in the counter top in an attempt to completely remove all undesirable fluids created by cooking units. It is well known that open hoods arranged in combination with suction or exhaust means in the prior art do not prevent the outflow of fluids such as hot air, steam smoke, grease-laden vapor and other gaseous contaminants into the air.
Steam, smoke, grease-laden vapor and other obnoxious fumes are known to form a deposit on the ceiling, walls and floors of adjacent enclosed areas such as kitchen and dining areas.
Slippery floors caused by grease-laden vapor are hazardous. Grease and smoke-laden walls create a constant repair problem; on the other hand smoke per se causes the needless activation of a nearby fire detector.
The present four-sided hood enclosure is further provided with controlled air inlet means for the purpose of preventing the above-indicated problems.
It is an object of the present invention to provide a hood for a suction-exhaust or down-draft type cooking range which improves the cooking efficiency by controlling the inlet air by adjustable inlet means and exhaust fluid by adjustable exhaust means while observing the internal hood area through a dome-shaped glass

located in the surface of the hood.
It is a further object of the present invention to improve the efficiency of a cooking hood when used with a suction-exhaust or down-draft type cooking range by controlling air influx to the internal portion of the hood by diagonally located adjustable inlet and exhaust means.
It is a further object of the present invention to improve the efficiency of a cooking hood when used with a suction-exhaust or downdraft type cooking range by controlling air influx to the internal portion of the hood by diagonally-located, adjustable inlet and exhaust means.
It is yet a further object of the invention to form the hood of a cast or welded body construction of rectangular configuration or dome-shaped top configuration.
It is still another object of the invention to use tempered steel, aluminum or stainless steel in the cast or welded hood body construction.
