Background Art

[0002] The content described in this part merely provides background information regarding the present invention and does not constitute prior art. In restaurants and ordinary households, in order to cook fried potatoes and other fried foods such as roasted chicken and tempura, it is common to heat a cooking fan filled with cooking oil to a temperature above a predetermined temperature and then put the object to be cooked into the oil for frying. Such objects to be cooked can be prepared in a frozen, refrigerated, normal temperature or warm storage temperature state. A typical high-efficiency fried food device used in a fast food environment can cook about 0.68 kg of frozen 0.25-inch fried food within about 3 minutes and 30 seconds, and the throughput of such a fried food device is about 27.22 kg / hr. However, recently, as consumers' interest in health has grown, they place a high value on healthy foods prepared with reduced use of oil or fat. However, due to the unique savory flavor that can only be enjoyed in fried foods, such foods, although harmful to health, still enjoy high popularity. Reflecting such concerns, recently invented air fryers can cook crispy fried dishes with hot air without oil, and with a unique combination of fast circulating air and oven components, they can cook fried foods quickly and easily. Generally, since air fryers only use air, they have less odor and steam compared to existing frying pans, are easy to use in daily life, safe, and economical. However, conventional air fryers have certain defects during use. In the case of conventional air fryers, the shape of the air fryer heating container is complex and heavy, so after cooking, there is the problem that it is inconvenient to clean. Moreover, there are many sharp parts in some places, and problems of getting injured during the cleaning process have occurred. On the other hand, since the detachment of the fan part that circulates hot air is troublesome and cleaning is inconvenient, improvement measures are required for this. Also, there was a problem that the hot air and the fan were separated, resulting in a decrease in heat transfer efficiency. In order to solve the above-mentioned problems of conventional air fryers, some related companies in Korea and overseas have conducted research on air fryers with easy fan detachment and increased heat transfer efficiency. However, for actual commercialization, the cost consumed to equip the structure is excessive, or even if not, the effect is not significant compared to the manufacturing cost of the corresponding device. Therefore, when compared with conventional air fryers, no cases of significant commercialization with reduced market competitiveness have been found. Therefore, as described above, there is a need to develop a device that can solve the problems of the conventional technology.

Summary of the Invention

Problems to be Solved by the Invention

[0003] The problem to be solved by the present invention is to supplement the disadvantages of the above-mentioned prior art, and the object of the present invention is as follows. First, it is intended to provide an IH air fryer in which a circulation part heated by an IH part directly supplies hot air and rotates at the same time, minimizing the configuration and increasing the heat transfer efficiency. Second, it is intended to provide an IH air fryer in which a magnetic body provided in a sealed IH part rotates, so that a circulation part provided with a magnetic counterpart rotates non-contact by magnetic force, increasing durability and simplifying the wiring circuit.

However, when it is determined that a specific description of such a known function or configuration in explaining a specific embodiment of the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. The above-mentioned objects, features, and advantages of the present invention will become more apparent through the following detailed description with reference to the accompanying drawings. However, the present invention can be modified in various ways and can include various embodiments. Hereinafter, specific embodiments will be illustrated in the drawings and described in detail. When it is determined that a specific description of a known function or configuration related to the present invention may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted. Also, the numbers used in the description process of this specification are merely identification symbols for distinguishing one component from another component. In addition, the suffix “part” regarding the components used in the following description is merely used for facilitating the preparation of the specification or is used in a mixed manner, and does not have a meaning or role that distinguishes them from each other by itself. FIG. 1 is a perspective view of an IH air fryer according to an embodiment of the present invention. An IH air fryer according to an embodiment of the present invention may include an IH unit 100, a circulation unit 200, and a loading unit 300. The IH unit 100 may include a housing 110 and an IH coil 190. The housing 110 can be formed of a rigid body (for example, a metal such as iron, aluminum, or copper, or a synthetic resin such as polystyrene (PS), ABS, polyacetal (POM), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), polycaprolactone (PCL), and polypropylene (PP)) can be selected). The housing 110 can be formed in a cylindrical shape as shown in FIG. 1, but alternatively, it can be formed in a polygonal shape. The housing 110 can be manufactured in an assembled manner or integrally formed so that the IH coil 190, the first rotating body, and the driving unit 120 can be inserted therein. The IH coil 190 is provided inside the housing 110 and can heat the circulation unit 200 by an electromagnetic induction method. The circulation unit 200 is disposed on one side of the IH unit 100, and the main body can be formed of a magnetic body A so as to be heated by the eddy current generated from the IH unit 100. The circulation unit 200 can circulate the fluid in the loading unit 300 disposed below the circulation unit 200 so as to transmit the thermal energy generated by the IH unit 100 to the food. As a means for circulating the fluid, preferably, as shown in FIG. 1, a fan can be selected, but it is formed in a cylindrical shape with a hollow accommodation space, and the inner peripheral surface of the cylinder rotates to form wind, or a porous perforated groove is formed on the inner peripheral surface of the cylinder, and the fluid can be circulated by a driving unit 120 such as an engine provided therein. The loading unit 300 is disposed on one side of the circulation unit 200 and can include a hollow accommodation space in which food is loaded so that the food can be cooked. A temperature sensor is provided inside the housing 110, and after the user sets the circulation unit 200 to a desired temperature during cooking by means of a display unit of a control unit arranged outside the housing 110, the user can start the operation of the circulation unit 200.

[0008] Figures 2 and 3 are perspective views showing various embodiments of the present invention. The IH unit 100 can include a drive unit 120 and a first rotating unit 130. The circulation unit 200 can include a second rotating unit 210. The first rotating unit 130 can include a magnetic body A, and the second rotating unit 210 can include a magnetic counterpart B corresponding to the magnetic body A. More specifically, as shown in FIG. 2, the drive unit 120 can be arranged inside the housing 110 in the IH unit 100. The first rotating unit 130 is connected to the drive unit 120 and rotates, and a magnetic body A is provided on one surface thereof. The second rotating unit 210 can be provided with a magnetic counterpart B corresponding to the magnetic body A of the first rotating unit 130 on one surface thereof. When the drive unit 120 is operated and the first rotating unit 130 rotates, the position of the magnetic body A fluctuates, and the magnetic counterpart B can rotate by magnetic force in response to the displacement of the magnetic body A. As shown in FIG. 2, in order to increase the circulation rate of convection, a panel portion protruding toward the lower surface of the loading unit 300 with a predetermined slope from one surface of the second rotating unit 210 can be included. The panel portion can have a shape in which its height gradually decreases from the outside of the second rotating unit 210 toward the central portion. The second rotating unit 210 can have a shape in which its width gradually decreases from the central portion toward the outside. As a result, the main body of the second rotating unit 210 is heated by the IH unit 100 in an electromagnetic induction manner, and the second rotating unit 210 can rotate in a non-contact manner when the first rotating unit 130 rotates. Therefore, the circulation unit 200 heated by the IH unit 100 directly supplies hot air to the loading unit 300 and rotates at the same time, minimizing the configuration, increasing the heat transfer efficiency, and shortening the cooking time. According to another embodiment of the present invention, the loading unit 300 of the IH air fryer can include a third rotating unit 310. The third rotating unit 310 can include a magnetic counterpart B corresponding to the magnetic body A. More specifically, as shown in FIG. 3, in the IH unit 100, the driving unit 120 can be disposed inside the housing 110. The first rotating unit 130 is connected to the driving unit 120 and rotates, and a magnetic body A is provided on one surface thereof. The third rotating unit 310 can be provided with a magnetic counterpart B corresponding to the magnetic body A of the first rotating unit 130 on one surface thereof. When the driving unit 120 is operated and the first rotating unit 130 rotates, the position of the magnetic body A fluctuates, and the magnetic counterpart B can rotate by magnetic force according to the displacement of the magnetic body A.

[0009] As a result, in the conventional air fryer, the hot air and the fan are separated, resulting in a decrease in heat transfer efficiency. In addition, the detachment of the fan part for circulating the hot air is troublesome, so there is a problem that cleaning is inconvenient. However, in the IH air fryer according to an embodiment of the present invention, the second rotating unit 210 and the third rotating unit 310 are heated by the IH unit 100 by electromagnetic induction, and the second rotating unit 210 and the third rotating unit 310 can rotate together in a non-contact manner when the first rotating unit 130 rotates. Therefore, the circulation unit 200 and the loading unit 300 heated by the IH unit 100 directly supply hot air and rotate at the same time, minimizing the structure and increasing the heat transfer efficiency, and shortening the cooking time. Furthermore, when the magnetic body A provided in the sealed IH unit 100 rotates, the circulation unit 200 provided with the magnetic counterpart B rotates non-contact by magnetic force, increasing the durability and simplifying the wiring circuit. According to another embodiment of the present invention, the circulation unit 200 can include a second rotating unit 210 that is directly connected to one side of the driving unit 120 and rotates. The loading unit 300 includes a hollow accommodation space in which one side of the driving unit 120 is directly connected and food is loaded therein, and can include a third rotating unit 310 that can be inserted into the loading unit 300 so as to be rotatable. More specifically, different from what is shown in FIGS. 2 and 3, the drive unit 120 disposed inside the housing 110 can be directly connected to the second rotating unit 210 or the third rotating unit 310. By directly connecting the second rotating unit 210 or the third rotating unit 310 to rotate, the circulation efficiency can be increased, and since additional components such as the magnetic body A and the magnetic counterpart B are not required, productivity can be improved and production costs can be reduced. FIG. 4 is a perspective view of the coupling part 111 and the part to be coupled 220 according to an embodiment of the present invention. FIG. 5 is a perspective view of the stirring unit 400 according to an embodiment of the present invention. The housing 110 includes a coupling part 111 formed on one surface of the housing 110, and the second rotating unit 210 can include a part to be coupled 220 that is connected to be detachable from the coupling part 111 so that the main body contaminated by cooking can be cleaned. As a result, the circulation unit 200 can be easily detached from the IH unit 100, so cleaning, sanitation, and hygiene management are easy. The loading unit 300 can include a drive unit 120 disposed between the lower surface of the loading unit 300 and the third rotating unit 310, and a first rotating unit 130 that is connected to the drive unit 120 and rotates to include the magnetic body A.

[0010] The loading unit 300 can include a stirring unit 400 that is disposed inside the third rotating unit 310 to stir food and includes the magnetic counterpart B. More specifically, as shown in FIG. 5, the drive unit 120 can be disposed between the lower surface of the loading unit 300 and the third rotating unit 310. The first rotating unit 130 is connected to the drive unit 120 and rotates, and the magnetic body A is provided on one surface thereof, and the stirring unit 400 can be provided with the magnetic counterpart B corresponding to the magnetic body A of the first rotating unit 130 on one surface thereof. When the drive unit 120 is operated and the first rotating unit 130 rotates, the position of the magnetic body A is changed, and the magnetic counterpart B can rotate by magnetic force according to the displacement of the magnetic body A. As a result, in the IH air fryer according to an embodiment of the present invention, since the stirring unit 400 can rotate in a non-contact manner as the first rotating unit 130 rotates, the food is uniformly stirred, and all the food can be evenly heated and cooked without tilting. Since it rotates in a non-contact manner, it is easy to clean and maintain cleanliness. This embodiment merely exemplarily illustrates the technical idea of the present invention. Those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations to this embodiment without departing from the essential characteristics of the present invention. This embodiment is not intended to limit the technical idea of the present invention, but to explain it. Therefore, the scope of rights of the present invention is not limited by this embodiment. The protection scope of the present invention should be interpreted according to the claims, and all technical ideas recognized as equivalent or equivalent thereto must be interpreted as being included in the scope of rights of the present invention.
