[0001] The present disclosure relates to a cooking appliance including an induction heating coil.

[0002] An induction heating cooking device is a cooking device that uses the principles of induction heating to heat a cooking vessel and cook food. The induction heating cooking device may include a cooking plate on which a cooking vessel is mounted, and an induction heating coil located beneath the cooking plate that generates a magnetic field when current is applied.

[0003] When current is applied to an induction heating coil, a magnetic field is generated, inducing a secondary current in the cooking vessel. This Joule heat is generated by the electrical resistance of the vessel itself. The Joule heat heats the vessel, thereby heating the food contained within.

[0004] Induction cooking appliances have a higher heat transfer rate than gas ranges that burn fossil fuels and heat the cooking utensils through the combustion heat, do not produce harmful gases, and reduce the risk of fire.

[0005] The cooking appliance may include a sensor for detecting vibrations in the cooking container generated as food in the cooking container boils. Based on the vibrations detected by the sensor in the cooking container, the output of the cooking appliance may be adjusted.

[0024] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the attached drawings.

[0025] FIG. 1 illustrates a cooking appliance according to one embodiment of the present disclosure. FIG. 2 illustrates an exploded view of some components of the cooking appliance according to one embodiment of the present disclosure.

[0026] Referring to FIGS. 1 and 2, the cooking device (1) may include a main body (10) that forms the exterior of the cooking device (1) and in which various components constituting the cooking device (1) are installed.

[0027] The cooking device (1) may include a cooking plate (100) provided on the upper side of the main body (10). The cooking plate (100) may have a flat shape on which a cooking container (90) can be placed. For example, the cooking plate (100) may include ceramic glass and / or tempered glass. For example, the cooking plate (100) may include heat-resistant glass that is strong against heat.

[0028] The cooking plate (100) may be made of various materials. The cooking plate (100) may have a property of not allowing light to pass through. In addition, the cooking plate (100) may have a property of transmitting a touch signal to a circuit board (12) provided on the lower side through touch.

[0029] An induction heating coil (11) is housed inside the main body (10) and can generate a magnetic field to inductively heat the cooking container (90). The induction heating coil (11) can be electrically connected to a main board provided inside the main body (10) via a wire. The induction heating coil (11) can be positioned below the cooking plate (100).

[0030] For example, when a driving current is supplied to the induction heating coil (11), a magnetic field can be induced around the induction heating coil (11). In particular, when a current whose size and direction change over time, i.e., an alternating current, is supplied to the induction heating coil (11), a magnetic field whose size and direction change over time can be induced around the induction heating coil (11).

[0031] The magnetic field surrounding the induction heating coil (11) can pass through the cooking plate (100) made of tempered glass and reach the cooking vessel (90) placed on the cooking plate (100).

[0032] Due to a magnetic field whose size and direction change over time, an eddy current that rotates around the magnetic field may be generated in the cooking container (90). This phenomenon of eddy currents being generated due to a magnetic field that changes over time is called electromagnetic induction. Due to the eddy current, electric resistance heat may be generated in the cooking container (90). Electric resistance heat is heat generated in a resistor when current flows through the resistor, and is also called Joule heat. The cooking container (90) is heated by this electric resistance heat, and food contained in the cooking container (90) may be heated.

[0033] When a magnetic field passes through the metal forming the cooking vessel (90), eddy currents are generated due to the resistance of the metal (e.g., iron) of the cooking vessel (90). The eddy currents generated in the cooking vessel (90) can generate heat in the cooking vessel (90) and heat the food inside.

[0034] In this way, the induction heating coil (11) can heat the cooking vessel (90) by using electromagnetic induction and electric resistance heat.

[0035] The cooking vessel (90) may include a pot, a frying pan, a steamer, a rice cooker, etc. The type of the cooking vessel (90) is not limited thereto. In this description, a pot will be used as an example.

[0036] For example, the induction heating coil (11) may include a first induction heating coil (11a) and a second induction heating coil (11b) having a different size and / or shape from the first induction heating coil (11). As an example, the first induction heating coil (11) may have a different output from the second induction heating coil (11b). As an example, the second induction heating coil (11b) may be provided in multiple numbers.

[0037] The cooking plate (100) may include a cooking zone (101) corresponding to an induction heating coil (11). A cooking vessel (90) may be placed in the cooking zone (101). The cooking zone (101) may be formed on the upper surface of the cooking plate (100). The number and location of the cooking zones (101) are not limited to the present invention.

[0038] For example, the cooking zone (101) may include a first cooking zone (101a) corresponding to a first induction heating coil (11a) and a second cooking zone (101b) corresponding to a second induction heating coil (11b). As an example, the second cooking zone (101b) may include an area in which a plurality of second induction heating coils (11b) are provided. The cooking device (1) can uniformly heat the cooking vessel (90) regardless of the position of the cooking vessel (90) in the second cooking zone (101b).

[0039] A user interface (102) may be provided on one side of the cooking plate (100) to receive control commands from a user and display operation information of the cooking device (1) to the user. However, the location of the user interface (102) is not limited to the cooking plate (100), and may be provided in various locations, such as the front and / or side of the main body (10). The user interface (102) may include a display unit (102a) and an input unit (102b).

[0040] A circuit board (12) may be placed under a cooking plate (100). The circuit board (12) may include a display (13) and a touch unit (14). The circuit board (12) may include a printed board assembly (PBA) including a display, a switch element, an integrated circuit element, etc. for implementing a user interface (102), and a printed circuit board (PCB) on which these are installed.

[0041] The display (13) may be arranged to correspond to the display portion (102a) of the cooking plate (100). The display (13) may indicate whether the cooking vessel (90) is heated by the induction heating coil (11). Accordingly, the user can check whether the cooking vessel (90) is heated through the display portion (102a).

[0042] The touch unit (14) may be arranged to correspond to the input unit (102b) of the cooking plate (100). The touch unit (14) may receive a touch signal from the input unit (102b). For example, the touch unit (14) may receive input using a capacitive touch method. However, the present invention is not limited thereto, and the touch unit (14) may also receive input using a pressure-sensitive touch method. The user may control the current flowing to the induction heating coil (11) through the input unit (102b) and determine the degree to which the cooking vessel (90) is heated.

The second frames (106) may be arranged on both sides and the rear of the cooking plate (100).

[0050] The second frame (106) may be provided to correspond to the first frame (16). A fastening hole (18) for fastening to the first frame (16) of the main body (10) may be formed in the second frame (106). The fastening hole (18) formed in the second frame (106) is referred to as a second fastening hole (18b). The second fastening hole (18b) may be formed at a position corresponding to the first fastening hole (18a). A plurality of second fastening holes (18b) may be formed on both sides and the rear of the second frame (130).

[0051] The cooking plate (100) can be secured to the upper portion of the main body (10) by the combination of the second frame (106) fixed to the lower portion of the cooking plate (100) and the first frame (16) of the main body (10).

[0052] A cooking device (1) may include a sensor (110) for detecting vibrations of a cooking plate (100). The cooking plate (100) may include a first side on which a cooking vessel (90) is mounted, and a second side on which a sensor (110) is positioned. The second side may be opposite the first side. For example, the first side may face upward, and the second side may face downward.

[0053] FIG. 3 is an exploded view illustrating the components for mounting a sensor of a cooking appliance according to one embodiment of the present disclosure to a cooking plate. FIG. 4 is an enlarged cross-section illustrating a portion of a cooking appliance according to one embodiment of the present disclosure where a sensor is located. FIG. 5 is a block diagram illustrating the configuration of a cooking appliance according to one embodiment of the present disclosure.

[0054] Referring to FIGS. 2 to 4, a cooking device (1) according to one embodiment of the present disclosure may include a sensor (110) for detecting vibration of a cooking vessel (90) placed on a cooking plate (100). The sensor (110) may detect vibration of the cooking vessel (90) generated as food contained in the cooking vessel (90) boils. The vibration of the cooking vessel (90) may be transmitted to the cooking plate (100), and the sensor (110) may detect vibration transmitted to the cooking plate (100).

[0055] When food in a cooking vessel (90) placed on a cooking plate (100) is heated, the food may flow. This flow of the food may physically affect the cooking vessel (90) to generate vibrations. The vibrations of the cooking vessel (90) may be transmitted to the cooking plate (100) on which the cooking vessel (90) is placed. The sensor (110) detects the vibrations of the cooking plate (100), thereby detecting the vibration pattern of the cooking vessel (90) through the cooking plate (100). Therefore, by analyzing the vibration pattern of the cooking vessel (90) that occurs during the boiling process of the food, it is possible to determine whether the food contained in the cooking vessel (90) is boiled.

[0056] For example, the sensor (110) may be a single-axis acceleration sensor that detects any one of the X-axis acceleration, the Y-axis acceleration, or the Z-axis acceleration of the cooking vessel (90). For example, the sensor (110) may be a two-axis acceleration sensor that detects two of the X-axis acceleration, the Y-axis acceleration, or the Z-axis acceleration of the cooking vessel (90). For example, the sensor (110) may be a three-axis acceleration sensor or a three-axis MEMS (Micro Electro Mechanical System) sensor that detects all of the X-axis acceleration, the Y-axis acceleration, and the Z-axis acceleration of the cooking vessel (90).

[0057] The sensor (110) can collect sensor data regarding the vibration of the cooking vessel (90). For example, the sensor (110) can obtain the acceleration of an axis corresponding to the vibration of the cooking vessel (90).

[0058] The sensor (110) can be positioned so as to be spaced apart from the induction heating coil (11) by a preset distance. As the sensor (110) is positioned so as to be spaced apart from the induction heating coil (11) by a preset distance, the sensor (110) can be prevented from being damaged by heat generated from the induction heating coil (11).

[0059] A sensor (110) may be placed between the first cooking zone (101a) and the second cooking zone (101b) to detect vibrations generated from a cooking vessel placed in the first cooking zone (101a) and vibrations generated from a cooking vessel placed in the second cooking zone (101b).

[0060] The cooking device (1) may include a metal bracket (120) attached to a cooking plate (100). The metal bracket (120) may be composed of metal. The metal bracket (120) may be attached to the cooking plate (100) by an adhesive (150). For example, the adhesive (150) may include a silicone adhesive or a double-sided tape.

[0061] The metal bracket (120) may include an adhesive receiving portion (125) for receiving at least a portion of an adhesive (150) when attached to the cooking plate (100). The adhesive receiving portion (125) may be formed to be spaced apart from the cooking plate (100) when the metal bracket (120) is attached to the cooking plate (100). When the metal bracket (120) is attached to the cooking plate (100), a space may be formed between the adhesive receiving portion (125) and the cooking plate (100). The adhesive (150) may be filled in the space formed between the adhesive receiving portion (125) and the cooking plate (100).

The sensor cover (130) may be configured to press the sensor (110) toward the cooking plate (100) when mounted on the metal bracket (120). For example, the sensor cover (130) may include a different material than the metal bracket (120). For example, the sensor cover (130) may include a material that is more flexible than the metal bracket (120).

[0064] The cooking appliance (1) may include a fastening member (140) for fastening the sensor cover (130) to the metal bracket (120). For example, the fastening member (140) may include a screw.

[0067] When the bracket fastening portion (123) and the cover fastening portion (133) are aligned, the fastening member (140) can be screw-connected to the bracket fastening portion (123) and the cover fastening portion (133). As the fastening member (140) is screw-connected to the bracket fastening portion (123) and the cover fastening portion (133), the sensor cover (130) can be mounted and fixed to the metal bracket (120).

[0068] The metal bracket (120) may include a bracket connecting portion (124) provided on one side opposite to the side where the bracket fastening portion (123) is provided. The sensor cover (130) may include a cover connecting portion (134) provided on one side opposite to the side where the cover fastening portion (133) is provided and capable of being connected to the bracket connecting portion (124).

[0069] For example, the bracket coupling portion (124) may have a groove or hole shape, and the cover coupling portion (134) may have a hook or protrusion shape that can be inserted into the bracket coupling portion (124), but is not limited thereto, and the shapes of the bracket coupling portion (124) and the cover coupling portion (134) may be provided in the opposite manner to that described above.

[0070] In order to attach the sensor cover (130) to the metal bracket (120), the cover attachment portion (134) is attached to the bracket attachment portion (124), the bracket attachment portion (123) and the cover attachment portion (133) are aligned, and then the attachment member (140) can be attached to the bracket attachment portion (123) and the cover attachment portion (133). The metal bracket (120) and the sensor cover (130) can be mutually fixed by the attachment of one side to the cover attachment portion (134) and the bracket attachment portion (124), and the other side can be mutually fixed by the attachment member (140) being attached to the bracket attachment portion (123) and the cover attachment portion (133).

[0071] The fastening member (140) may be provided to be screw-coupled to the bracket fastening member (123) and the cover fastening member (133) in a direction in which the sensor cover (130) presses the sensor (110) toward the cooking plate (100). As the fastening member (140) is coupled to the bracket fastening member (123) and the cover fastening member (133) in a direction in which the sensor cover (130) presses the sensor (110) toward the cooking plate (100), the adhesion between the sensor (110) and the cooking plate (100) may be improved.

[0072] The cooking device (1) may include a buffer member (160) to alleviate shock transmitted from the cooking plate (100) to the sensor (110). The buffer member (160) may be provided between the sensor (110) and the cooking plate (100). For example, the buffer member (160) may include a material that is more flexible than the cooking plate (100).

[0073] For example, the buffer member (160) may be provided so that a cross-section perpendicular to the direction from the cooking plate (100) toward the sensor (110) has a rectangular shape. The buffer member (160) may have a cross-section perpendicular to the up-down direction having a rectangular shape. The upper surface of the buffer member (160) may contact the cooking plate (100), and the lower surface of the buffer member (160) may contact the sensor (110). The buffer member (160) may extend along the edge of the sensor (110).

[0074] In a cooking device (1) according to one embodiment of the present disclosure, since the sensor (110) can be brought into close contact with the cooking plate (100) when the fastening member (140) presses the sensor cover (130), the vibration detection performance of the cooking container (90) transmitted through the cooking plate (100) can be improved. In a cooking device (1) according to one embodiment of the present disclosure, since the degree of close contact between the sensor (110) and the cooking plate (100) can be improved, the vibration detection performance of the sensor (110) can be improved.

[0075] Referring to FIG. 5, the cooking device (1) includes a user interface (102), a sensor (110), an induction heating coil (11), a control unit (80), and a communication unit (70).
