Description

Technology Field

[0001] The present invention relates to an induction-heating fryer, and more specifically, to an induction-heating fryer using an eco-friendly, non-magnetic container that generates waves, magnetic field lines, and far-infrared rays throughout the oil used in the fryer by using ultrasonic waves having a certain wave generated during induction heating to cause vibration on the heating plate. Background Technology

[0002] Generally, a deep fryer heats the oil while it is contained, making it possible to cook fried food conveniently.

[0003] These deep fryers cooked food by heating the oil through the heat generated by heaters equipped on the outside or inside of the frying container, but recently, deep fryers capable of heating the oil using an induction heating method have been developed and are being used.

[0004] Induction heating utilizes the principle of electromagnetic induction to generate heat. When an electric current flows, it creates a magnetic field, which induces an electric current in a metal object, thereby generating heat.

[0005] However, during induction heating, the location where electromagnetic waves are induced is not constant, making it difficult to heat the oil uniformly across the entire surface; consequently, this leads to a problem where the condition of the fried food cooked is inconsistent.

[0006] Consequently, problems arise where the taste of the fried food is poor due to localized thermal shock, and oil oxidation proceeds rapidly, leading to increased oil consumption.

[0007] In this regard, prior art document 1 (Registered Patent 10-2264131 Induction Heating Fryer Using a Non-Magnetic Container) discloses a configuration that allows frying to be cooked using an induction heating device.

[0008] However, prior art 1 has a structure in which an induction heating plate is fixedly installed in a frying container, and when the magnetic force generated from the coil of the magnetic force generating part is transmitted to the induction heating plate, heat is emitted in the horizontal direction by the induced current, so heat is generated intensively at the location where the coil is equipped, and consequently, a problem arises in which the temperature of the oil is not uniformly distributed.

[0011] The purpose is to provide an induction heating fryer using a non-magnetic container that can generate waves throughout the heating plate and rapidly induce the magnetic flux to flow evenly throughout by forming slits in the vertical direction in the same direction as the magnetic flux flow in the heating plate to facilitate the flow of magnetic flux and ultrasonic vibrations through the slits.

[0012] In addition, the purpose is to provide an induction-heating fryer using a non-magnetic container that can provide healthy and more delicious fried food by providing a magnet at the bottom of the non-magnetic frying container so that a magnetic field and ultrasonic waves generated by an induced current are evenly formed throughout the entire non-magnetic frying container, thereby heating the oil temperature uniformly throughout, and extending the oil life through the physical and chemical reactions of oil molecules and internal expansion caused by ultrasonic waves, magnetic field lines, and far-infrared rays. means of solving the problem

[0022] Herein, when the vibrating heating plate is installed in the heating plate installation part, a collision prevention (maintaining a certain distance) magnet is further provided between the heating plate mounting part and the main body mounting part.

Specific details for implementing the invention

[0028] The present invention relates to an induction-heating fryer, and is characterized in that, in particular, by using ultrasonic waves having a certain wave generated during induction heating to cause vibration in the heating plate, waves are generated throughout the oil used in the fryer, thereby rapidly raising the temperature of the oil used for frying and enabling uniform heating throughout.

[0029] Hereinafter, an induction-heating fryer using a non-magnetic container according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0030] FIG. 1 is an overall perspective view of an induction-heating fryer using a non-magnetic container according to an embodiment of the present invention, FIG. 2 is a cross-sectional view showing the overall configuration of an induction-heating fryer using a non-magnetic container according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view of an induction-heating fryer using a non-magnetic container according to an embodiment of the present invention.

[0031] Referring to FIGS. 1 to 3, the present invention comprises a fryer body (100) manufactured to be able to cook fried food, and a non-magnetic frying container (200) installed in the fryer body (100) to form a space inside which oil is contained to be cooked fried food, and capable of cooking fried food by heating the contained oil.

[0032] And it is configured to include a work coil (300) that is installed to completely surround the outer surface of the above-mentioned non-magnetic frying container (200) and generates a magnetic field as current flows when power is applied.

[0033] At this time, a fixing plate (310) is provided on the outer side of the work coil (300) to fix the work coil (300) so that it is in close contact with the outer side of the non-magnetic frying container (200), and the work coil (300) is fixedly installed so that it does not move by means of the fixing plate.

[0034] And the non-magnetic frying container (200) is configured to include a vibrating heating plate (400) that forms a thin plate shape on the inner side and is installed to be movable along the inner surface of the non-magnetic frying container (200).

[0035] Here, the vibrating heating plate (400) is heated by magnetic field induction by allowing the magnetic field generated from the work coil (300) to pass through the non-magnetic frying container (200), and vibrates into fine waves by the ultrasonic waves generated during electromagnetic induction, thereby enabling the generation of waves.

[0036] At this time, the fryer body (100) is provided with a heating plate installation part (110) that allows the vibrating heating plate (400) to be installed movably.

[0037] The heating plate installation part (110) is fixedly installed between the fryer body (100) and the heating plate installation part (110), and is configured to include a heating plate installation bracket (111) that supports a vibrating heating plate (400) so that it can move.

[0038] And it is configured to include a bracket fixing bolt (112) that can fix the heating plate installation bracket (111) between the fryer body (100) and the non-magnetic frying container (200).

[0039] The above heating plate installation bracket (111) can be installed between the fryer body (100) and the non-magnetic frying container (200) using a single bracket fixing bolt (112), and a bolt fastening hole (111a) is formed to fasten the bracket fixing bolt (112).

[0040] And a heating plate mounting portion (111b) is formed that extends toward the inside of the non-magnetic frying container (200) and is provided to form a vertically bent structure upward.

[0041] The above vibrating heating plate (400) is mounted on the upper part of the heating plate mounting part (111b) and is provided with a main body mounting part (410) that forms a hook shape bent downward.

[0042] The above main body mounting part (410) is mounted on the upper part of the heating plate mounting part (111b) and is not completely fixed, but is mounted so as to be movable with a hook structure.

[0043] And in the vibrating heating plate (400), a plurality of induction slits (420) are formed at regular intervals in the vertical direction in the part that is submerged in oil and heats the oil inside the non-magnetic frying container (200).

[0044] The above-mentioned induction slit (420) is formed along the direction of magnetic flux flow when the vibrating heating plate (400) induces magnetic flux and ultrasonic waves to heat the oil, thereby facilitating the flow of magnetic flux and inducing ultrasonic vibrations so that they flow together with the direction of magnetic flux flow.

[0045] The above vibrating heating plate (400) may be made of stainless steel, and accordingly, it does not corrode and enables stable heating and ultrasonic induction.

[0046] As a result, the heating effect by magnetic flux can be increased, and by allowing ultrasonic vibrations to flow along the induction slit (420), the vibrating heating plate (400) vibrates evenly throughout, thereby increasing the heating effect and the vibration effect.

[0047] Meanwhile, a magnet (500) may be further provided at the bottom of the above-mentioned non-magnetic frying container (200).

[0048] The magnet (500) facilitates the smooth flow of magnetic flux and ultrasonic waves from the bottom of the non-magnetic frying container (200) to the vibrating heating plate (400), thereby enabling the non-magnetic frying container (200) to be firmly and stably fixed to a place where a magnet can be attached, such as iron.

[0049] Meanwhile, the above magnet (500) is a magnet containing cobalt as a main component and generally has strong magnetic force.

[0050] These magnets (500) are made of an alloy of cobalt, iron, nickel, etc., and have the characteristic of maintaining magnetism at high temperatures.

[0051] Accordingly, the non-magnetic frying container (200) is heated and can perform stably even at high temperatures.

[0052] Figure 4 is a reference graph for the application of the thickness of a vibrating heating plate in an induction-heating fryer using a non-magnetic container according to one embodiment of the present invention.

[0053] Referring to FIG. 4, the ultrasonic induction performance of the vibrating heating plate (400) decreases as it becomes thicker, and if it is too thin, it is easily deformed and the heating performance is insufficient.

[0054] Accordingly, it is preferable that the thickness of the vibrating heating plate (400) be 0.4 mm, which is the minimum usable thickness of stainless steel.

[0055] FIG. 5 is an exemplary diagram illustrating the state in which magnetic flux and ultrasonic vibration flow through a slit formed in a vibrating heating plate in an induction-heating fryer using a non-magnetic container according to an embodiment of the present invention.

[0056] Referring to FIG. 5, the induction slit (420) is formed in a vertical direction along the direction of magnetic flux flow and ultrasonic vibration, and it is preferable that the width be formed to be 0.3 mm to optimize the induction performance of magnetic flux flow and ultrasonic vibration while minimizing deformation of the vibrating heating plate (400).

[0057] FIG. 6 is an example diagram illustrating a state in which a round portion is formed to facilitate the movement of a heating plate installation portion and a vibrating heating plate in an induction-heating fryer using a non-magnetic container according to the first embodiment of the present invention.

[0058] Referring to FIG. 6, in which a vibrating heating plate (400) is movably installed in a heating plate installation part (110), the mounting part can be mounted in a round shape to enable smoother movement.

[0059] To this end, a curved portion (111c) having an upwardly convex shape is formed at the end portion where the main body mounting portion (410) is mounted on the heating plate mounting portion (111b), and a curved support portion (411) that is positioned above the curved portion (111c) and can facilitate smooth flow through a curved structure may be formed on the inner side where the main body mounting portion (410) is mounted on the heating plate mounting portion (111b).

[0060] As a result, the mounting part forms a round shape, enabling smooth vibration even with small ultrasonic vibrations and minimizing impact caused by vibrating collisions.

[0061] FIG. 7 is an example diagram illustrating a state in which a vibrating heating plate is installed spaced apart from the heating plate installation part by a collision prevention magnet in an induction heating type fryer using a non-magnetic container according to the second embodiment of the present invention.

[0062] Referring to FIG. 7, when the vibrating heating plate (400) is installed in the heating plate installation part (110), a collision prevention magnet (430) may be further provided between the heating plate mounting part (111b) and the main body mounting part (410).

[0063] The above collision prevention magnet (430) is installed so as to face each other with the same polarity on the heating plate mounting part (111b) and the main body mounting part (410), respectively, so that the heating plate mounting part (111b) and the main body mounting part (410) are kept separated from each other and vibrate, thereby preventing noise caused by collision and further activating the vibration caused by ultrasound by the restoring force due to magnetism.
