[0024] Referring to FIGS. 2 and 5, the first heating unit 100 may include a first body 110 formed of a first accommodation part 111 for accommodating a first heat generation member 120, and the first heat generation member 120 provided at the first accommodation part 111 of the first body 110 may be formed of any one of ceramic, a coil, carbon, a crystal tube, a PTC (Positive Temperature Coefficient) heater, an infrared ray lamp, and a halogen lamp so as to generate heat. The generated heat may be transferred via a heat transfer plate 130 provided integral while covering the top of the first body 110 in order for the heat generated by the first heat generation member 120 to be transferred.

[0025] As illustrated in FIGS. 2 and 4, the heat transfer plate 130 may be passed through its center, thus forming a tubular oil discharge tube 141 which extends vertical together with the through hole in the downward direction of the perforated heat transfer plate 130, and an end of the oil discharge tube 131 communicates with the bottom surface of the first accommodation part 111.

[0026] Referring to FIGS. 2 and 4, an oil collector 150 may be disposed below the first body 110 of the first heating part 100. More specifically, the container-shaped-shaped oil collector 150 is provided below the first body 110 corresponding to the lower end of the oil discharge tube 131 in order for impurities, for example, oil, etc. to be discharged via the oil discharge pipe 131 of the heat transfer plate 130 and to be inputted and collected.

[0027] As illustrated in FIG. 4, the cooking plate 140 disposed at the top of the heat transfer plate 130 may include an oil guide piece 142 protruding from a lower, outer circumferential end of an oil discharge hole 141 formed in the center, wherein the oil guide piece 142 is disposed inside the oil discharge tube 131 of the heat transfer tube 130, by which the impurities contained in the foods being cooked on the upper surface of the cooking plate 140 can be inputted through the oil discharge hole 141 and can be collected into the oil collector 150 through the oil discharge tube 131 of the heat transfer plate 130.

[0028] Referring to FIGS. 2 and 6, the second heating unit 200 is able to generate heat by means of the second heat generation part 230 provided at the second accommodation part 211 of the second body 210 and discharge the generated heat to the first heating unit 100 corresponding to the second heating unit 200, so the foods on the cooking plate 140 of the first heating unit 100 can be cooked. The second heating unit 200 is equipped with a reflection plate 220 configured to reflect heat generated by the second heat generation member 230, and a protection net 240 configured to support the second heat generation member 230 while making sure a user's safety.

[0029] As illustrated in FIGS. 2 and 3, there may be provided a pillar 300 which is able to guide the upward and downward rotations of the second heating part 200 while maintaining a predetermined space between the first heating unit 100 and the second heating unit 200. The bottom of the pillar 300 can be fixed at a surface of one side of the first heating unit 100 through an engaging hole 302 formed at a surface of the lower end of the pillar 300. A rotation piece 301 formed at the top of the pillar 300 may be coupled between a pair of engaging pieces 201 which are disposed spaced apart at a surface of one side of the second heating unit 200, and may be connected and assembled by means of a hinge 202, whereby the second heating unit 200 can move upward and downward.

[0030] A through hole may be formed passing through the left and right sides of the rotation piece 301 formed at the top of the pillar 300. Another through hole may be formed at a surface of one side of the second heating unit 200, while passing through the left and right surfaces of each of a pair of the engaging pieces 201, so the rotation piece 301 can be coupled between a pair of the engaging pieces 201, whereby each through hole communicates with each other, and the hinge 202 may be disposed inside the communicated through holes. In this state, the second heating unit 200 can rotate upward and downward with respect to the pillar 300.

[0031] As illustrated in FIG. 8, as an external electricity (not illustrated) is supplied to the first heating unit 100 and the second heating unit 200, the first heating unit 100 and the second heating unit 200 generate heat at the first heat generation member 120 and the second heat generation member 230 in association with the temperature adjusting parts 160 and 250 provided at the first and second heating units 100 and 200 through a timer 102 by a power switch 101. The power switch 10 may be formed of a limit switch which is able to instantly disconnect the supply of the power if the first and second heating units 100 and 200 become horizontal states or fall down due to an external impact. The power can be supplied from an external power through the power switch 101 and can be supplied to the timer 102. The timer 102 is employed to set cooking time, and the cooking time can be set based on the adjusted cooking time. If the set time of the timer 102 passes, the power supply may be automatically disconnected, so the power supply to the first and second heat generation parts 120 and 230 of the first and second heating units 100 and 200 can be disconnected.

[0032] In this way, electricity can be supplied to the temperature adjusting parts 160 and 250 provided at the first and second heating units 100 and 200 via the timer 102, and the temperature adjusting parts 160 and 250 are configured in such a way that electricity can be independently supplied or cannot be independently supplied to the first heat generation member 120 of the first heating unit 100 and the second heat generation member 230 of the second heating unit 200. If the temperature is over a predetermined temperature level after the temperature adjusting parts 160 and 250 are set to the set appropriate temperatures, the electricity supply may be disconnected or if less than the appropriate temperature level, the electricity can be supplied. Consequently, the electricity can be controlled by the temperature adjusting parts 160 and 250.

[0033] It is obvious that the configuration wherein the external electricity, the power switch 101, the timer 102, the temperature adjusting parts 160 and 250, and the first and second heat generation members 120 and 230 are connected via a power cable (not illustrated) to supply electricity, is referred to a known-art.

[0034] The multi-purpose heating device 10 formed of the first and second heating units 100 and 200 is invented for the sake of use of a warm heating in addition to a cooking purpose. In this way, the first heating unit 100 may be used for cooking, and the second heating unit 200 may be used for cooking or warming and heating based on individual power supply control methods. The second heating unit 200 may rotate upward and downward with the aid of the pillar 300, and after the cooking is finished, the user can easily pick up food on the cooking plate 140 of the first heating unit 100, and the surrounding environment can be heated warm with the aid of the second heat generation member 230 of the second heating unit 200, thus providing a warming and heating function. The angle may be adjusted in order for the engaging piece 201 of the second heating unit 200 and the rotation piece 301 of the pillar 300 to rotate upward and downward by the hinge 202, so the heat can be emitted to the portion which is set as a heat generation by the second heat generation member 230 of the second heating unit 200.

[0035] Moreover, the first and second heating units 100 and 200 are formed in a tetrahedron structure, but are not limited thereto. As illustrated in FIG. 7, the first and second heating units may be manufactured in a polygonal shape, for example, a circular structure, etc.

[0036] The heat transfer plate 130 of the first heating unit 100 may be formed of a ceramic plate or a tempered glass plate. The multi-purpose heating device 10 of which the cooking plate 140 is made of a transparent tempered glass can be manufactured.

[0037] The heat transfer plate 130 is made of a material which is able to quickly absorb heat, for example, a ceramic plate or a tempered glass plate, when the heat is emitted from the first heat generation member 120 of the first heating unit 100, and the heat transfer plate 130 which has absorbed the heat, is made of a transparent tempered glass for the heat to be quickly transferred to the cooking plate 140.

[0038] Referring to FIGS. 9 and 10, there is provided a multi-purpose heating device 10 which is equipped with a protective case 400 inserted inside of the first body 110 of the first heating unit 100, wherein a first protrusion strip 112 protruding inward may be formed at an inner circumferential surface of the first body 110 of the first heating part 100, and a second protrusion strip 401 protruding outward may be formed at an outer circumferential surface thereof, so the second protrusion strip 401 can be hooked by the first protrusion strip 112 and can be seated. A third protrusion strip 402 protruding inward may be formed at an inner circumferential surface of the top of the second protrusion strip 401.

[0039] A third accommodation part 403 may be formed inside of the protective case 400, wherein the first heat generation member 120 is accommodated in the third accommodation part 403. A through hole may be formed in the center of the bottom surface of the inside, wherein the oil discharge tube 131 of a heat shielding plate 130 is inserted inside of the through hole. The second protrusion stripe 401 of the protective case 400 is blocked by the first protrusion stripe 112 formed at the inner side of the first body 110 of the first heating unit 100, and the second protrusion strips 401 may surface-contact surface with the top of the first protrusion stripe 112, thus blocking the protective case 400 from descending downward of the first body 110 or separating from the same. This may contribute to preventing the heat from being discharged toward the bottom of the first body 110 of the first heating unit 100 and outward of the first body 110. A space, therefore, can be formed between the bottom surface of the protective case 400 and the bottom surface of the first body 110, by which it is possible to block the heat from being discharged downward of the first body 110 and to the outside.

[0040] Since the first heat generation member 120 is accommodated in the third accommodation part 403 of the protective case 400, the protective case 400 can be easily attached or detached from the first body 110 when it needs to repair or exchange the first heat generation member 120.

[0041] Since the third protrusion stripe 402 is formed at the inner side of the inner circumferential surface of the protective case 400, the circumference, namely, the outer side surface of the heat shielding plate 130 may be stopped by the third protrusion stripe 402 when seating the heat shielding plate 130 at the top of the protective case 400, by which it is possible to prevent the circumference thereof from separating downward into the inside of the protective case 400. The present invention is able to provide an assembled structure which allows the heat shielding plate 130 to be easily attached or detached.

[0042] As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
