Description

Description ADVANCED ROASTER WITHOUT SMOKE Technical Field

[1] The present invention relates to an improved smokeless roaster having a gutter for receiving fat or water drops dropped from food when baking the food to prevent smoke from giving off or soot from being produced, in which the gutter is provided at a center and rim thereof with grooves to be filled with water not to allow a surface of the food positioned on a center and edge of a grid to be dry. Background Art

[2] A grill or roaster is generally used to directly bake food such as fish, meat or the like.

[3] The grill or roaster is heated by heating means (for example, charcoal, butane gas, briquette, etc.) to bake the food. If the heat to bake the food is very high, the food may be burned or sticks to a grid of the grill or roaster, before the food is well done.

[4] If the food sticks to the grid, it is very cutr ersome to clean the grill or roaster. Of course, the burned food is harmful to the human body.

[5] Consequently, due to the reasons, the grid should be frequently exchanged to prevent the food from sticking thereon in restaurants. Frequent exchange increases the number of exchanged grids, which means the increased amount of cleaning work.

[6] The grill or roaster includes a hot plate for indirectly baking the food, such as flyer, and a net-type grid for directly baking the food, in which many holes are formed on a surface thereof. The hot plate bakes the food using a hot plate heated by the heating means. The grid bakes the food using the heat passing through the holes formed on the surface of the grid.

[7] The hot plate is generally provided at a center thereof with recessed portions to collect fat or moisture resulted from the food at one position. For the net-type grid, the fat or moisture generated from the food drops on the charcoal through the holes formed on the surface of the grid, thereby giving off smoke or making soot. In some cases, a fire breaks out in the grill or roaster.

[8] Recently, in order to prevent clothing from absorbing the smoke generated at baking the food, over the grill or roaster is provided a corrugated duct for sucking the smoke from the hot plate or grid and discharging the sucked smoke outwardly. In addition, an air sucking fan or duct may be provided under or over a table to discharge the smoke or unpleasant smell. As such, the conventional grill or roaster is required for an exhaust or ventilation unit to discharge the smoke outwardly.

[9] t wever, the exhaust or ventilation unit causes a person inconvenience, since it interferes with a meal or obstructs a field of vision. In addition, the forcible suction of the smoke generated at baking the food causes a surface of the food to be easily dry, which turns the taste of the food. Of course, it results in an increased cost for installing an accessory provision. Disclosure

[10] Therefore, an object of the present invention is to solve the problems involved in the prior art, and to provide an improved roaster having a guide portion for receiving and guiding fat or water drops generated from food when baking the food not to burn the fat, and water containing grooves positioned under the guide portion, in which the water containing grooves are installed across heating means to prevent a surface of the food from being dry.

[11] According to one aspect of the present invention, there is provided a smokeless roaster including a heating pot with heating means therein and a grid positioned in the heating pot to bake food, the roaster comprising: a gutter including at least one bridge groove crossing the heating pot and filled with a desired amount of water; and a fat guide portion for collecting fat or moisture produced by the food into the bridge groove.

[12] The gutter further includes rim grooves formed at both ends of the bridge groove so that the gutter ixmnunicates with the bridge groove.

[13] The gutter installed in the heating pot may have any one of a circular shape, a rectangular shape and a polygonal shape.

[14] In a conventional roaster having a gutter, food positioned on an edge of a grid is exposed to a steam, but food positioned on a center of the grid is easily dry. But, according to the present invention, a water containing groove is installed across heating means or a rim groove is further provided to an edge of the gutter, so that the food positioned on the center and edge of the grid is properly baked.

[15] According to another feature of the present invention, a heatproof plate is further provided to a bottom of the bridge groove, thereby attenuating the heat supplied to the center of the grid and thus preventing the food from being burned black or adhered to a surface of the grid.

[16] Also, according to another feature of the present invention, the heatproof plate and the bridge groove have a V shape in cross section. It easily transfers the heat supplied from the heating means upwardly, and prevents quick boil of the water contained in the bridge groove. [17] In addition, a desired space is provided between the heatproof plate and the bridge groove, or the space is filed with a heat isolating material. Description of Drawings [18] The above objects, other features and advantages of the present invention will become more apparent by describing the preferred embodiment thereof with reference to the accompanying drawings, in which: [19] Fig. 1 is a top view of a gutter of a roaster according to the present invention.

[29] Fig. 11 is a cross-sectional view of a base attached to a bottom of a water container according to the present invention, [30] Fig. 12 is an exploded perspective view of a roaster according to another embodiment of the present invention. Best Mode [31] Reference will now be made in detail to preferred eirbodiments of the present invention, examples of which are illustrated in the accompanying drawings. [32] Fig. 1 is a top view of a gutter 20 of a roaster according to the present invention, and Fig. 2 is a cross-sectional view taken along a line A-A in Fig. 1. [33] As will be seen from Figs. 1 and 2, a gutter 20 includes bridge grooves 15, a rim groove 16, and heatproof plates 35. [34] The gutter 20 includes, as shown in Figs. 6 to 8, the bridge grooves 15 crossing a heating pot 30 and containing a desired amount of water, and heat passage openings 25 through which heat generated from the heating pot 30 passes to bake food.

[35] The food is baked by the heat generated from the heating pot 30 and passed through the heat passage openings 25, and steam generated from the bridge groove 15 prevents the food from being burned black or scorched on a grid due to the heat generated from the heating pot 30. A plurality of the bridge grooves 15 may be provided, if necessary.

[36] Fat drops from the baked food, for example, meat, onto the heat base 30, which gives off smoke. In order to reduce the smoke, the grid is adapted so that the fat drops on a center of the bridge groove 15.

[37] The rim groove 16 is installed to both ends of the bridge groove 15, i.e., an edge of the gutter 20, such that the water in the rim groove 16 is ixmnunicated with the water contained in the bridge groove 15.

[38] In this case where the gutter 20 is provided with the grooves 15 and 16 at the center and edge of the gutter, when the food is baked on the grid, the water contained in the grooves vaporizes into steam by heating means, such that the steam passes through the entire surface of the grid to provide a surface of the food with moisture to soften the food (in particular, meat).

[39] Preferably, the bridge groove has a width more narrow than that of the heat passage opening. A time needed for baking the meat or food and flesh of the meat are affected by a ratio of a surface area of the heat passage opening to a surface area of the bridge groove. For example, if the width of the bridge groove is wider than that of the heat passage opening, since an amount of the heat transferred to the food is reduced, the food is slowly done. By contrast, if the width of the bridge groove is narrower than that of the heat passage opening, the food is quickly overdone or scorched to the grid.

[40] The heatproof plates 35 are provided under the bridge groove 15 to cover the bridge groove 15, and have a V-shaped cross section.

[41] The heat generated from the heating pot 30 is smoothly guided into the heat passage openings 25 of the gutter 20 by the heatproof plates 35.

[42] The heatproof plates 35 prevent the water contained in the bridge grooves 15 from being easily heated due to the heat generated from the heating pot 30. Spedfically, the heatproof plates 35 prevent quick boil of the water contained in the bridge grooves 15 and bake the food slowly to prevent the food from being burned black.

[43] Preferably, the heatproof plate 35 is spaced apart from the bridge groove 15 at regular intervals to obtain the above effects. Alternatively, a typical heat isolating material may be provided in a space formed between the heatproof plate 35 and the bridge groove 15.

[44] Fig. 3 is a top view illustrating an alternative embodiment of a gutter according an embodiment of the present invention, in which the gutter has a rectangular shape. The gutter may be applied to various shapes (i.e., polygonal shape) according to the shape of the roaster, if necessary.

[45] Fig. 4a is a perspective view illustrating a gutter 20 seated on a heating pot 30 according to an embodiment of the present invention, in which the heating pot 30 is provided at an edge thereof with a rim groove 16. Alternatively, Fig. 4b is a perspective view illustrating a gutter 20 seated on a heating pot 30 according to another alternative embodiment of the present invention, in which the heating pot is provided with the rim groove 16 therein. The gutter 20 is seated on the heating pot 30 such that the rim groove of the gutter is disposed inside the heating pot.

[46] Fig. 5a is a view of a grid 10 installed onto the gutter. The grid 10 includes a grate made of wire, a one-piece cast grid formed by casting, and the like. In the embodiment, the grid is provided at a bottom thereof with fat guide portions 11 for collecting the fat or moisture into the bridge grooves 15, so as to prevent the fat or water drops created by the food from being dropped in the grate or cast grid.

[47] The fat guide portions 11 have a corrugated shape to smoothly guide the fat along the grid. An edge of the gat guide portions 11 corresponds to the bridge groove 15.

[48] The entire fat and moisture resulted from the food is collected by the bridge groove 15 only, so that it can prevent soil of the food due to soot or ashes to be produced by the fat and moisture drop onto the heating pot 30.

[49] Fig. 5b is a view illustrating a rectangular roaster according to another embodiment of the present invention.

[50] Fig. 6 is a view illustrating a heatproof plate 35 according to another embodiment of the present invention. The heatproof plate 35 is installed on seating grooves 31 formed on a portion of an upper portion of the heating pot 30. The heatproof plate 35 includes a gutter 20 having bridge grooves 15. The bridge groove has the same shape as a V-shaped groove of the heatproof plate 35. It intends to easily cast the gutter 20 with the bridge grooves 15 formed thereon.

[51] Fig. 7 is a cross-sectional view of the gutter 20 mounted on the heating pot 30. Bridge grooves 15 are formed across the heating pot 30, and a rim groove 16 is formed along an edge of the heating pot 30. Fig. 8 schematically shows a roaster according to the embodiment of the present invention, in which a heating pot 30 and a gutter 20 are seated in a water container 50, and a grid 10 is laid on the water container 50.

[52] Fig. 7 schematically shows the smokeless roaster according to the present invention, in which the rim groove 16 of the gutter 20 is formed at the edge of the heating pot 30. Fig. 8 is a schematic view of the roaster according to the present invention in use, in which if the food laid on the grid 10 positioned on the water container 50 is baked by the heat, the fat produced from the food is collected into the fat guide portions 11, and then is dropped into the bridge groove 15 of the gutter 20.

[53] Fig. 9 is a cross-sectional view of a base attached to a bottom of the water container according to the present invention, in which a base 55 is mounted to one side of the rim groove 16 in such a way that a height of a V-shaped bridge groove 15 is identical with a height of the rim groove 16.

[54] Fig. 10 is an exploded perspective view of a roaster according another embodiment of the present invention. An auxiliary heating pot 33 is mounted on a heating pot 30, and has heat shielding plates 34 to position heating means at a position corresponding to a heat passage opening 25 of a gutter 20. With the construction, it can prevent the bridge groove 15 of the gutter 20 from being directly contacted with the heat, so that evaporation of the water contained in the bridge groove 15 is delayed.

[55] While the present invention has been described and illustrated herein with reference to the preferred errbodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made therein without departing from the spirit and scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of this invention that come within the scope of the appended claims and their equivalents. Industrial Applicability
