[7] According to an installation place, the side surface part of the frier is in close contact with a wall surface of the place. Therefore, the frier having the working lever formed at the side surface has troubles in the installation thereof.

[8] Further, as the matter of the characteristics of the frier, outer parts of the oil pot, that is, both side surface plates of the oil pot are kept at a high temperature all the time by radiation heat of the oil received in the oil pot.

[9] In order to discharge the oil used for a predetermined time, users may contact the side surface plates in the procedure of manipulation of the working lever, which is mounted to the side surface part of the frier. Therefore, the prior art frier has disadvantages such as danger of burns and the inconvenience of the manipulation of the working lever.

[10] In addition, the working lever formed for discharging the oil deteriorates at the side surface part of the main body of the frier degrades appearance of the frier.

[11] The working lever formed at the side surface part of the main body of the frier is protruded, so that the packaging or transporting of the frier becomes complicated.

[12] Even though the frier as shown in Fig. 4 has the working lever formed at the front surface part of the main body, this prior art has still disadvantages in manufacture and manipulation since the ball valve is opened or closed by using the link unit.

[13] Therefore, the present invention is derived to resolve the above and any other disadvantages of the prior art.

[14] Therefore, the present invention is derived to resolve the above and any other disadvantages of the prior art.

[15] There is an object of the present invention to provide an oil draining system for a frying machine in which cooking oil received in an oil pot and used for a predetermined time may be discharged to the outside from a front surface part of a main body of the frier by using an oil draining element.

[16] There is another object of the present invention to provide an oil draining system for a frying machine which may improve reliability and competitiveness of the frier. Technical Solution

[18] According to the oil draining device of the present invention, the draining element for discharging cooking oil received in the oil pot is formed with the oil draining handle and the working lever at a side of a front surface part of the main body for the convenience of installation and manipulation. Therefore, the working lever connected to the oil draining handle may be manipulated right and left with respect to the rotation shaft for discharging the cooking oil received in the oil to the outside, so that the convenience in the installation and the manipulation of the frier may be improved. [19] Therefore, the reliability and the competitiveness of the product may be improved.

Advantageous Effects

[20] According to the present invention in the above structure, a working lever has a draining handle mounted at a front surface part of a main body, so that the installation convenience of a frier may be improved.

[21] Also, the draining handle is formed at the front surface part of the main body, so that the manipulation convenience of users may be improved.

[22] Further, waste oil received in an oil pot may be discharged by manipulating the draining handle at the front surface part of the frier instead of a side surface part thereof, so that safety in the oil draining work may be improved.

[23] Therefore, the oil draining system for a frying machine according to the present invention is very advantages for improving the reliability and competitiveness. Brief Description of the Drawings

[24] The objects, features and advantages of the present invention will be more clearly understood from the following detailed description in conjunction with the accompanying drawings, in which:

[29] Now, a frier according to the present invention will be described in more detail with reference to the accompanied drawings.

[30] Fig. 1 is a perspective view showing a shape of a frier according to a preferred embodiment of the present invention, Fig. 2 is a front view showing a construction of an oil draining system for a frying machine according to the present invention, Fig. 3 is a side view showing a construction of an oil draining system for a frying machine according to the present invention, and Fig. 4 is a side view showing a construction of an oil draining system for a frying machine according to a prior art.

[31] Referring to Fig. 1 to Fig. 4, in an oil draining system for a frying machine according to the present invention, an oil draining element 30 is mounted at a side of a front surface of a frier in a direction of an oil pot 20 positioned at a rear part in the main body, that is, in the longitudinal direction, so that a working lever 50 controls directional conversion of a ball valve 40, which is mounted to a draining hole 11 of the oil pot 20.

[32] The working lever 50 has a draining handle 52 mounted at a front part thereof, and a fixing part 51 mounted at a rear part thereof.

[33] The fixing part 51 is mounted with a rotation shaft 60 in connected with the ball valve 40, which controls the draining hole 11 at a bottom surface part of the oil pot 20, so that the direction of the ball valve 40 is converted by the manipulation of the working lever 50.

[34] The draining handle 52 mounted at the front part of the working lever 50 is axially fixed by a valve housing 41 and the rotation shaft 60, so that the ball valve 40 rotates by simply rotating the draining handle 52 right and left at the front surface part of the main body 10 for discharging waste oil, as shown in Fig. 2 and Fig. 3.

[35] Differently from the prior art oil draining structure for a frier, the draining handle

52 is formed at the front surface part of the main body 10 and manipulated right and left, so that the working lever 50 rotates the ball valve 40 in association with the right and left manipulation of the draining handle 52. Therefore, the waste oil is discharged from the oil pot 20 to an external waste oil tank 80 through the draining hole 11.

[36] An additional element such as a holding protrusion or a holding element is preferably mounted in a manipulation range of the draining handle 52 for alternatively restraining the right and left rotation of the draining handle 52, thereby resolving problems caused by false manipulation of the draining handle 52.

[37] A holding piece 70 is mounted at a rear part of the draining handle 52 to be axially supported by the draining handle in the alternative manner for preventing false manipulation of the draining handle 52, as shown in Fig. 3.

[38] The holding piece 70 may be substituted with any general control elements.

[39] Therefore, according to the most principal characteristics of the present invention, the waste oil may be discharged by the simple rotation manipulation of the draining handle 52 at the front surface part of the main body 10 instead of using any link structures for the sake of the manipulation convenience.

[40] Although the foregoing description has been made with reference to the preferred embodiments, it is to be understood that changes and modifications of the present invention may be made by the ordinary skilled in the art without departing from the spirit and scope of the present invention and appended claims.
