The present invention may be implemented in various forms and is not limited to the drawings which will be described.

(20) First, an electric grill having an oil mist and smoke purification and circulation system of the present invention includes: a grill main body, an oil pan installed at one inner side of a lower portion of the grill main body to be slidable and in which water is stored; a suction fan provided at one side of the oil pan and configured to suction air including oil mist, smoke, heat, and a smell and blow the air to the water stored in the oil pan; a heat dissipation plate spaced apart in an upward direction from the oil pan and the suction fan to be coupled, spaced apart from inner side wall portions of both sides of the grill main body to be coupled to the inner side wall portions, and provided with a plurality of suction holes and discharge holes formed in upper portions of both side ends of an upper portion of a periphery of a grill plate in a longitudinal direction at intervals; a heater support installed to be spaced apart from an upper portion of the heat dissipation plate; a heater seated on the heater support; and the grill plate in which a seating groove of the heater is formed in a lower portion thereof, and a side cross-sectional surface has a V shape to be seated on the heater.

(21) That is, referring to FIGS. 1 to 7, an electric grill having an oil mist and smoke purification and circulation system of the present invention includes: a grill main body 100; an oil pan 108 installed at one inner side of a lower portion of the grill main body to be slidable and in which water is stored; a suction fan 111 provided at one side of the oil pan and configured to suction air including oil mist, smoke, heat, and a smell and blow the air to the water stored in the oil pan; a heat dissipation plate 130 spaced apart in an upward direction from the oil pan 108 and the suction fan 111 to be coupled, spaced apart from inner side wall portions of both sides of the grill main body 100 to be coupled to the inner side wall portions, and provided with a plurality of suction holes 102 and discharge holes 120 formed in upper portions of both side ends of an upper portion of a periphery of a grill plate in a longitudinal direction at intervals; a heater support 106 installed to be spaced apart from an upper portion of the heat dissipation plate 130; a heater 105 seated on the heater support 106; and the grill plate 101 in which a seating groove 107 of the heater 105 is formed in a lower portion thereof, and a side cross-sectional surface has a V shape to be seated on the heater.

(22) In this case, first oil discharge ports 103 are formed in the grill plate 101 along a central-longitudinal direction at a predetermined interval to protrude from and pass through a lower portion of the grill plate 101, and second oil discharge ports 104 are formed in the heat dissipation plate 130 along a central-longitudinal direction at a predetermined interval to protrude from and pass through an upper portion of the heat dissipation plate 130 so that the first oil discharges port 103 are correspondingly inserted thereinto, and thus the oil is discharged through the first oil discharge ports 103 and the second oil discharge ports 104, thereby preventing pollution of the heat dissipation plate due to the oil.

(23) Here, referring to FIG. 6, in a description of an air circulation structure of the present invention, the air suctioned by the suction tan is circulated in one direction through the plurality of suction holes 102 of the heat dissipation plate 130 and a space formed by the heat dissipation plate 130 and both inner side wall portions of the grill main body 100 which are spaced apart from each other, and the air including the oil mist, smoke, heat, and smell generated on the grill plate 101 is suctioned by the suction fan 111 and introduced through the plurality of suction holes 102 at one side of the heat dissipation plate 130 and the space formed by one side of the heat dissipation plate 130 and inner side wall portions at one side of the grill main body 100 which are spaced apart from each other, and comes into contact with the water stored in the oil pan 108 to remove the oil mist, smoke, heat, and smell, and then is circulated through a space formed by the other side of the heat dissipation plate 130 and an inner side wall portion at the other side of the grill main body 100 spaced apart from each other and a plurality of discharge holes 120 at the other side of the heat dissipation plate 130, thereby purifying and circulating the air including the oil mist, smoke, heat, and smell.

(24) In this case, a detachable filter cartridge 112 coupled in a longitudinal direction may be installed in a space formed by the heat dissipation plate 130 and both inner side wall portions of the grill main body 100 which are spaced apart from each other, to completely remove the oil mist, smoke, heat, and smell.

(25) Further, FIG. 7 is an enlarged cross-sectional view of FIG. 6A, and referring to FIG. 7, a Coanda air guide configured to guide the oil mist, smoke, heat, and smell, which are suctioned, so that the oil mist, smoke, heat, and smell come into contact with the water stored in the oil pan 108, is installed between the oil pan 108 and the suction fan 111, and the Coanda air guide includes a guide main body part 110, a Coanda curve part 122, and a Coanda nozzle 115 so that the oil mist, smoke, heat, and smell blown by the suction fan 111 flow in a downward direction to the water stored in the oil pan 108 through the Coanda nozzle due to a Coanda effect, and thus the contact between the oil mist, smoke, heat, and smell and the water increases.

(26) In the above, the Coanda effect refers to a principle or property that changes a flowing direction of fluid so that the fluid flows in close contact with a curved surface when the fluid flows along the curved surface, and in the present invention, the air including the oil mist, smoke, heat, and smell flows through the guide main body part 110, the Coanda nozzle 115, and the Coanda curve part 122, and since a flow path of air is guided in a direction downward from the oil pan 108 using the Coanda curve part 122, the contact between the air and water increases.

(27) That is, in the air blown from the suction fan 111, an airflow which passes through the Coanda nozzle 115 and an airflow 113 which flows along an inner surface of the Coanda air guide are formed, and in this case, since the airflow which passes through the Coanda nozzle 115 serves as an air curtain, and an airflow 114 which flows along the inner surface of the Coanda air guide is controlled in a downward direction, the contact between the air and water increases.

(28) Further, referring to FIG. 5, after the electric grill guide is used, since the Coanda air guide is configured so that the guide main body part 110 and the suction fan 111 may be sequentially detached from an upper end of the Coanda air guide and washed, or may be detached to replace components even in the case of a partial breakdown or wear, a lifespan of the electric grill may be increased by maintaining cleanliness.

(29) Meanwhile, as shown in FIGS. 8 and 9, in the electric grill having an oil mist and smoke purification and circulation system of the present invention, an oil fence 200 spaced apart from a right side of the suction fan in an upward direction to be coupled and coupled to the right inner side wall portion of the grill main body may be provided between the suction fan 111 and the right inner side wall portion of the grill main body to prevent pollution of the right inner side wall portion of the grill main body from oil generated as the oil mist in the air which passes through the plurality of suction holes 102 is condensed.

(30) That is, the oil fence 200 may include: an oil fence liner 201 coupled in close contact with the right inner side wall portion of the grill main body; and an oil pooling part 202 formed in an U-shaped cross-sectional shape in a direction toward the suction fan 111 from a lower portion of the oil fence liner to collect and remove oil which flows through the oil fence liner.
