DESCRIPTION OF DRAWINGS
The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a perspective view of a conventional eco-friendly frying pan lid in use;
FIG. 2 is an exploded perspective view of the eco-friendly frying pan lid of FIG. 1;
FIG. 3 is a perspective view of an eco-friendly cooking lid in accordance with the present invention; and

BEST MODE
Now, embodiments of the present invention will be described with reference to the accompanying drawings.
With reference to FIGS. 3 and 4, an eco-friendly cooking lid 100 in accordance with the present invention includes a lid main body 10, inlets 40, a handle 70, and an exhaust pipe 90.
The lid main body 10 includes a hemispherical body 13 having a hollow structure and formed of heat-resistant transparent glass, openings 15 formed on the side surface of the body 13, and hinge coupling units 17 provided at positions of the body 13 adjacent to the openings 15. Here, the outer circumference of the lower end of the body 13 is combined with the upper end of a frying pan 200. Further, in order to prevent difficulty in observing the cooking state at the inside of the lid main body 10 with the naked eye due to generation of fog within the lid main body 10 during cooking, a water-repellent coating is applied to the inner surface of the cooking main body 10.
Although this embodiment describes that two openings 15 and two hinge coupling units 17 are provided, one opening 15 and one hinge coupling unit 17 or three or more openings 15 and three or more hinge coupling units 17 may be formed.
Further, although this embodiment describes the lid main body 10 as having a hemispherical shape with a hollow structure, the shape of the lid main body 10 may be variously modified.
The inlet 40 includes a cover 41 provided with one end coupled with the hinge coupling unit 17 by a hinge pin Pn so as to open and close the opening 15 formed on the side surface of the body 13, a grasping terminal 43 formed on the upper surface of the cover 43, and a sealing weight 45 provided on the lower surface of the cover 43 to hermetically seal the opening 15. Here, in order to prevent leakage of steam or oil mist through a gap between the opening 15 and the cover 41, the sealing weight 45 is formed by coating the surface of a disc-shaped weight formed of stainless steel, copper or aluminum with non-toxic silicone.
Further, through the inlet 40 of the present invention, food is input to the frying pan or a cooling tool is input to the frying pan.
At least one air vent 47 is formed on the cover 41 of the inlet 40.
The handle 70 is formed at the upper end of the lid main body 10 and includes a grasping part 71 extending to a long length so as to be easily grasped by a user. Further, in the handle 70, a through hole 73, which communicates with an opening (or a hole) formed at the upper end of the lid main body 19 and into which the lower end of the exhaust pipe 90 is inserted, is formed at the end of the grasping part 71.
The exhaust pipe 90 includes an exhaust pipe main body 91 provided with a lower end 91a inserted into the through hole 73, and a connection member 95 provided with a lower end 95a separably combined with the upper end of the exhaust pipe main body 91. Here, although the exhaust pipe 90 may be formed of metal, the exhaust pipe 90 in accordance with this embodiment is formed of a heat-resistant synthetic resin so as to achieve light weight and, particularly, is easily separated from the handle 70 so as to be conveniently cleaned.
The upper end of the connection member 95 may be combined with a corrugated tube communicating with a kitchen hood so as to forcibly exhaust contaminated gas, such as steam or oil mist generated during cooking.
Further, a removable charcoal filter may be installed at the lower end 91a of the exhaust pipe main body 91 and the lower end 95a of the connection member 95, thus filtering oil mist.
As apparent from the above description, in the eco-friendly cooking lid of the present invention, when a user grasps and lifts the grasping terminal 43 formed on the upper surface of the cover 41, the cover 43 is rotated about the hinge coupling unit 17 and thus opened and, on the other hand, when the user grasps and lowers the grasping terminal 43, the sealing weight 45 provided on the lower surface of the cover 41 hermetically seals the opening 15 and thus leakage of steam or oil mist to the outside during cooking may be prevented.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
