This invention relates to an improved cooking apparatus and the like.
In particular, one embodiment of this invention provides a. cooking apparatus having heating means and support means to support article means that is to be affected by the output of the heating means. Electrode means are carried by the ap-- paratus and are disposed in electrically spaced relation to the article means. Means are provided for imposing a potential differential between the article means and the electrode means to tend to cause soiling particles of the article means to move toward the electrode means during the heating thereof by the heating means to tend to prevent soiling of the cooking apparatus by such particles. Means are also provided for creating an air movement that tends to direct the soiling particles toward such electrode means. Means can also be provided to ionize such soiling particles so that the same are more readi 1y attracted by the electrode means.
Accordingly, it is an object of this invention to provide an improved cooking apparatus or the like having one or more of the novel features set forth above as hereinafter shown or described.
Other objects, uses and advantages of this invention are apparent upon a reading of this description which proceeds with reference to the accompanying drawings forming a part thereof and wherein:
HO. 1 is a front schematic view of a cooking oven or apparatus of this invention.
P16. 2 is a fragmentary cross-sectional view illustrating another cooking apparatus of this invention.
A cooking oven 604 is schematically illustrated and is generally indicated by the reference numeral 604 in FIG. 1 and can comprise an outer casing structure 700 defining a. conventional oven cavity 701.
The oven cavity 701 can be provided with conventional broil-heating means 702 and bake-heating means 703 in order to cook food 704 or the like disposed in a suitable cooking receptacle or pan 705 and being supported on conventional rack means 706 of the cooking apparatus 604.
However, it is well known that during normal cooking operations of an oven or the like, cooking soil collects on the interior walls of the oven cavity 701 which must be subsequently cleaned.
Accordingly, it is a feature of this invention to tend to reduce such cooking soil on the interior walls of the cooking cavity 701 by utilizing the electrostatic or potential differential feature of this invention.
For example, a pair of electrode plates 707 are disposed in the oven cavity 701 and are electrically insulated from the cas-,
A pair of collecting troughs 709 are each associated with each plate 707 and are electrically insulated from the oven casing 700.
The electrode plates 707 and associated troughs 709 are respectively adapted to be interconnected to one side 607 of the electrostatic device 606as suitable lead means 710 as illustrated whereby one potential can be imposed on the plates 707 and troughs 709 by the electrostatic device 606 during the cooking operations.
ln'this manner, as the food 704 is being cooked in the oven 701, the particles thereof that normally tend to leave the food 704 and splatter against and soil the internal surface means of the oven 701 will be at ground potential and, therefore, will be attracted toward the plates 707 by the aforementioned potential differential being created therebetween by the electrostatic device 606 whereby such soiling particles will collect on and soil the plate means 707 and if a too large amount of such soiling products collect on the plate means 707 so as to tend to drip off the same, the dripping soiling products will drip into the troughs 709 to be retained therein by the potential being imposed thereon by the electrostatic device 606.
Therefore, it is believed that most of the oven-soiling particles produced during cooking operations in the oven 701 will be collected on the plates 707 so that the housewife or the like need only clean such plates 707 in a periodic manner without requiring complete cleaning of the entire interior surface walls of the oven 701. v
In particular, the plates 707 and/or troughs 709 can be so constructed and arranged that the same are readily insertable and removable from the oven 701 so that the same can be more readily cleaned at the kitchen sink or the like.
Also, it may be found that the electrode plates 707 could actually comprise sheets of aluminum foil whereby the same could be readily disposable and need not be cleaned because the same could be replaced by new sheets of aluminum foil from the conventional aluminum foil rolls that housewives or the like utilize in their kitchens for food wrapping purposes and the like.
While the cooking apparatus 604 has been previously described as having the food 704 at ground potential while the electrode means 707 and 709 are at one potential, it is to be understood that the apparatus 604 could be so constructed and arranged that the supporting racks 706 thereof could have an equal and opposite potential imposed thereon by the electrostatic device 606 being electrically interconnected to the support means 706 thereof or the like so that the soiling particles would have one potential imposed thereon by the electrostatic device 606 to more readily tend to cause the same to collect on the electrodes 707 having an equal and opposite potential disposed thereon by the electrostatic device 606.
While the above-described operation takes place during a cooking operation, it is to be understood that such electrode means 707 could be utilized during a high-temperature burnoff cleaning operation to collect soiling particles as the same are affected by the heating means and leave the interior surface means of the oven 701 so that the same will not be redeposited on another part of the surface means to be required to be removed by the heating operation. Thus, it can be seen when viewing FIG. 1, soilage from previous cooking operations will be'deposited on the interior surface means of the oven 701 and will be subject to a heating operation by the heating means 702 and/or 703 during a burnoff cleaning operation whereby soiling particles from the soilage on the interior surface means will be driven outwardly therefrom by the heating means and will be collected by the electrode means 707 in the manner previously described.
In order to increase the amount of soilage being collected by the electrode means 707 during the aforementioned cooking operations and/or burnoff cleaning operations, means can be provided for causing an air movement between the soiling particles and the electrode means 707 to direct the soiling particles toward the electrode means 707 by such moving air. In addition, means can be provided to ionize such soiling particles so that the same will be more readily attracted by the electrode means 707.
In particular, a suitable air-circulating means or fan 711 can be provided in the oven 701 as illustrated in FIG. 1 so as to cause an air circulation within the oven 701 that tends to move the sailing particles from the article means 704 or the soiling particles from the interior surface means of the oven 701 toward the electrode, means 707 whereby it is believed that the majority of the airborne ,smoke'and particles that normally cause soilage in the oven 701 will be directed by the aircirculating means 71 1 toward the electrode means 707 so that the soiling particles will be collected by the electrode means 707 in the manner previously described.
In addition, the air-circulating means 711 can include suitable electrode means charged by the line 712 so as to ionize the soiling particles being directed by the aircirculating means 711 with a charge opposite to the charge on the electrode means 707 so that such ionized soiling particles will be more readily attracted by the electrode means 707 as the soiling particles are being directed thereto by the air-circulating means 7l l. v
While the air-circulating means 711 and ionizing means 712 are illustrated as being disposed in one location in the oven 701, it is to be understood that such air-circulating means 711 and ionizing means 712 can be provided in any suitable location within the oven 701 and the same can comprise a plurality of air-circulating means and ionizing means in a plurality of different locations within the oven 701, as desired.
Also, the air-circulating means 711, electrode means 707 and ionizing means 712 can comprise slightly modified conventional room and/or chimney electrostatic precipitators suitably located within the oven 701 for the purpose previ ously described.
it is also believed that such electrostatic potential differential feature can be utilized in preventing soilage in a range top cooking operation while being utilized with or without the air-circulation means 711 and/or the ionizing means 712 previously described. Accordingly, a range top 605 is schematically illustrated in FIG. 2 and comprises a top heating element means 800 for supporting and heating a cooking vessel 801 in a conventional manner.
However, as normally occurs during range top cooking operation, cooking splatter and spillage can occur whereby such spillage is normally permitted to pass through an opening means 802 in the range top frame 803 to be received in a collecting pan 804. Sometimes the soiling products collected in such pan 804 are themselves further heated by the heating While the form of the invention now preferred been disclosed as required by the statutes, other forms may be used, all coming within the scope of the claims which follow.
