In addition, according to the present invention, the inclination of the inner pot 10 can be changed from vertical to horizontal inclination by the operation of the second driving unit 90, and various dishes such as boiling, frying, and baking can be prepared according to the inclination of the inner pot 10. manufacturing is possible

The cover part 100 can be modified in various ways within the technical concept of opening and closing the open inlet part 52 of the case part 50 . The cover part 100 according to an embodiment of the present invention has a disk shape, and a hot air supply part 110 is installed inside the cover part 100 . The cover part 100 is detachably installed on the upper side of the case part 50 and opens and closes the upper side of the inner pot 10 .

8 is a bottom view of the hot air supply unit 110 according to an embodiment of the present invention.

As shown in FIGS. 7 and 8 , the hot air supply unit 110 is installed inside the cover unit 100, sucks air in the inner pot 10, and discharges the air to the inside of the inner pot 10, and hot air Various modifications are possible within the technical idea of cooking the food 120 as the above. The hot air supply unit 110 according to an embodiment of the present invention includes a fan module 111 and a duct unit 115.

The fan module 111 is installed inside the cover part 100 and sucks air inside the inner pot 10 by rotating the fan. A motor and a rotating fan are provided inside the fan module 111, and air is moved by rotation of the fan.

The fan module 111 is installed on the upper side of the suction grill 101 of the cover part 100 and sucks air from the inner pot 10 through the suction grill 101 .

The duct unit 115 is connected to the fan module 111, and various modifications are possible within the technical idea of forming an air flow path for guiding air discharged from the fan module 111 to the lower side of the cover unit 100. The duct part 115 is shaped like a conduit for guiding the movement of air. One side of the duct part 115 is connected to the fan module 111 and the other side of the duct part 115 is the discharge grill 102 of the cover part 100. ) is connected to

The air discharged through the duct unit 115 comes into contact with the inner pot 10 heated by the heating unit 40 and after the temperature rises, it moves to the lower side of the inner pot 10 to heat the food 120 . The other side of the duct part 115 is installed in a downwardly inclined direction in order to discharge air in a direction toward the inner pot 10 .

In addition, the discharge grill 102 facing the duct unit 115 may also be installed inclined in a direction toward the inner pot 10 . Therefore, the air passing through the discharge grill 102 and the discharge grill 102 in turn comes in contact with the heated inner pot 10 and moves to the lower side of the inner pot 10 along the inner surface of the inner pot 10 after being heated.

The food 120 is cooked by induction heating in which the heating unit 40 heats the inner pot 10 to heat the food 120 in the inner pot 10, and the air coming out of the hot air supply part 110 is heated in the inner pot. After the temperature rises in contact with (10), the food 120 is heated so that the food 120 can be cooked with convective heat.

The cooking apparatus 1 according to an embodiment of the present invention can heat the food 120 to various temperatures by using induction heating and hot air to heat the food 120 . The operation of the hot air supply unit 110 located on the upper part of the inner pot 10 removes unnecessary moisture from the food 120 and at the same time makes the outside of the food 120 crispy to implement a cooking function like an air fryer.

Hereinafter, an operating state of the cooking apparatus 1 according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

After opening the cover part 100 and opening the upper side of the inner pot 10, put food 120 in the inner pot 10 and combine the cover part 100 with the case part 50 to close the upper part of the inner pot 10 .

When an operation signal is input to the control unit provided in the cooking device 1, the control unit operates the heating unit 40, the hot air supply unit 110, the first driving unit 60, and the second driving unit ( 90) is operated.

A cooking apparatus 1 according to an embodiment of the present invention is a method of cooking food 120 by induction heating in which a heating unit 40 heats an inner pot 10 and an operation of a hot air supply unit 110. All methods of cooking the food 120 by convective heat may be used or only one method may be selectively used. Therefore, according to the present invention, the cost of purchasing a device can be reduced compared to individually purchasing the cooking device 1 having various heat sources.

When cooking such as soup, the second driving unit 90 does not operate and only the first driving unit 60 operates to rotate the inner pot 10 . There is a vertical line passing through the center of the inner pot 10 and extending vertically, and rotation in a circumferential direction based on this vertical line is defined as a first rotation direction D1. The inner pot 10 rotates along with the lifter 20 in the first rotational direction D1 by the operation of the first drive unit 60 . The inner pot 10 can be modified in various ways, such as being able to rotate clockwise or counterclockwise.

The food 120 contained in the inner pot 10 may be cooked by operating only the heating unit 40 that heats the inner pot 10 . In addition, the hot air supply unit 110 is operated to heat the food 120 contained in the inner pot 10 with the hot air circulating inside the inner pot 10 .

Describing the operation of the hot air supply unit 110 , the fan module 111 is operated to suck air in the inner pot 10 into the fan module 111 . The air sucked into the fan module 111 is moved to the duct unit 115 and then discharged toward the inner surface of the inner pot 10 to be heated and then moved to the inside of the inner pot 10 to heat the food 120 . Then, the air moved to the upper side of the inner pot 10 is sucked into the fan module 111 again, and the operation is repeated.

The operation of the hot air supply unit 110 creates a flow of air circulating inside the inner pot 10 and the cover unit 100 .

Meanwhile, the tilt of the pot may be adjusted according to the cooking process of the food 120 by the operation of the second driving unit 90 . Therefore, according to the present invention, various types of foods 120 such as soup and stir-fried food can be cooked in one cooking device 1, saving time required for cooking and improving consumer satisfaction.

The operation of the second driving unit 90 rotates the inner pot 10 in the second rotational direction D2. When the inner pot 10 rotates toward the front of the cooking device 1, when the central axis is referred to as a horizontal reference axis, the rotation direction around the horizontal reference axis is set as the second rotation direction D2.

The inner pot 10 and the case portion 50 are rotated in the second rotational direction D2 corresponding to the length of the outer gear 54 . The inner pot 10 and the case part 50 are rotated in an inclined shape toward the front of the cooking device 1 in an upright state. The inner pot 10 and the case portion 50 according to an embodiment of the present invention do not rotate toward the rear of the cooking device 1 in a standing state.

The second driving unit 90 outputs forward rotation and reverse rotation so that the inner pot 10 can be moved in the same motion as a wok. The cooking apparatus 1 according to an embodiment of the present invention can implement a motion of turning the wok, and since the tilt of the inner pot 10 can be adjusted, food 120 can be cooked in various cooking modes, thereby increasing consumer satisfaction. can improve

On the other hand, the cooking device 1 according to an embodiment of the present invention can recognize a recipe as a barcode or QR code through linkage with a mobile device, and when there is no recognition code, the user can designate a recipe. can provide.

As described above, the present invention has been described with reference to the drawings illustrated, but the present invention is not limited by the embodiments and drawings disclosed in this specification, and various modifications are made by those skilled in the art within the scope of the technical idea of the present invention. It is obvious that variations can be made.
