DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made in detail to the present preferred embodiment of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiment is described below in order to explain the present invention by referring to the figures.

A grilling apparatus according to an embodiment of the present invention serves to prevent food from being burnt due to overheating of a grill and serves to reduce a cooking period of the food. As illustrated in FIGS. 1 and 2, the grilling apparatus includes a cabinet 10 which defines an external appearance of the grilling apparatus and is opened at a top thereof to form an opening 11. A grill 30 on which food 20 is placed is set in the cabinet 10 through the opening 11. A heating unit 40 is installed in the cabinet 10 to heat the food 20.

The grill 30 includes a plurality of pipes 31 to support the food 20 to be cooked. Two water tanks 50 are connected to respective ends of each of the plurality of the pipes 31 to supply water to each of the pipes 31. Therefore, although heat generated from the heating unit 40 is transmitted to each of the pipes 31 of the grill 30 during cooking of the food 20, each of the pipes 31 is not heated above a predetermined temperature of 100° C., because the water circulates in each of the pipes 31, thus preventing an overheating of the grill 30 during cooking of the food 20 and preventing the food 20 from being undesirably burnt due to overheating of the grill 30.

Each of the water tanks 50 is seated, respectively, on a seating part 12 which is provided on each side of the opening 11 of the cabinet 10. The grill 30 is set in the opening 11 between the two water tanks 50, and is downwardly bent, at a portion thereof, to form a food supporting part 32 supporting both side surfaces of food 20. The food supporting part 32 is positioned in the cabinet 10 below the opening 11.

Further, the heating units 40 are provided at predetermined positions adjacent to both sides of the food supporting part 32 in the cabinet 10 so as to allow simultaneous heating of both of the side surfaces of the food 20 which is supported by the food supporting part 32. The grilling apparatus allows both of the side surfaces of the food 20 to be simultaneously cooked by the food supporting part 32 and the heating unit 40, so the user does not need to turn the food 20 over during cooking of the food 20, thus reducing the cooking time of the food 20.

Since the heating unit 40 comprises one or more heat reflecting plates 41 on which electric heating elements 42 are arranged, heat generated from the electric heating elements 42 is reflected by the reflecting plate 41, thus enhancing the heating efficiency of the heater unit 40.

Several food supporting parts 32 may be formed on the grill 30 so as to simultaneously cook a large amount of the food 20 using the grilling apparatus. In this case, a number of the heating units 40, which are provided, respectively, at predetermined positions adjacent to respective sides of the food supporting parts 32, is increased corresponding to a number of the food supporting parts 32. That is, the number of the food supporting parts 32 may be, for example, two. In this case, three heating units 40 are required to be provided at positions adjacent to respective sides of the food supporting parts 32. The heating units 40 may be provided between the two food supporting parts 32, respectively, to irradiate heat such that the two food supporting parts 32 are heated at a same time.

Each of the water tanks 50 is provided at a portion thereof with a cap 51. The cap 51 is opened at a top thereof to refill the water tanks 50 with water. As illustrated in FIG. 3, a water level sensor 52 is provided in each of the water tanks 50 to sense an amount of the water contained in each of the water tanks 50.

Each of the water level sensors 52 senses the amount of the water contained in one of the water tanks 50 so as to prevent the water in each one of the water tanks 50 from being reduced below a predetermined amount due to an evaporation of the water, thus preventing the food 20 from being burnt or charred due to overheating of the grill 30. Further, each of the water level sensors 52 is connected to an alarm buzzer (not shown) or an alarm lamp (not shown). When a respective water level sensor 52 senses that an amount of the water contained in a respective water tank 50 is less than the predetermined amount, the alarm buzzer emits an alarm sound or the alarm lamp is lit such that a user easily notices a lack of the water contained in the respective water tank 50.

The operation and effect of the grilling apparatus according to the present invention will be described in the following in detail.

When cooking the food 20 using the grilling apparatus is desired, the cap 51 is opened and an appropriate amount of the water is supplied to each of the water tanks 50 so that the water is fed into each of the plurality of the pipes 31 of the grill 30 which communicates with the water tanks 50. Next, the food 20, such as meat or bread, is placed in the food supporting part 32, and the one or more heating units 40 start operating. At this time, heat generated from the one or more heating units 40 is transmitted to the food 20 to cook the food 20 supported in the food supporting part 32.

In this case, heat generated from the one or more heating units 40 is simultaneously transmitted to the food 20, as well as to the grill 30. However, the grill 30 is not heated above a predetermined temperature of 100° C., because the water circulates in each of the plurality of pipes 31 constituting the grill 30. Since the grill 30 is not overheated, the food 20, which is in contact with the grill 30, is not burnt, and the food 20 does not get scorched and/or stick to the grill 30, thus allowing the grill 30 to be easily cleaned. Further, the food 20 is suitably cooked by only the heat generated from the one or more heating units 40.

While cooking the food 20, opposite side surfaces of the food 20 are simultaneously cooked due to the food supporting part 32 of the grill 30 being designed to support the opposite side surfaces of the food 20 and the one or more heating units 40 being designed to radiate heat in opposite directions toward the opposite side surfaces of the food 20. Therefore, the user does not need to turn the food 20 over during cooking of the food 20, thus reducing a cooking period to cook the food 20 and increasing convenience of use of the cooking apparatus.

As is apparent from the above description, the a grilling apparatus, which is designed such that water is circulated in a grill and heat generated from a heating unit is simultaneously transmitted to opposite side surfaces of food is provided, thus preventing the food from being burnt due to an overheating of the grill, and reducing a cooking period to cook the food.

Although an embodiment of the present invention has been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
