Description

Cooking appliances

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

[0002] An induction heating cooking device is a cooking device capable of cooking food by heating a cooking vessel using the principle of induction heating. An induction heating cooking device may be equipped with a cooking plate on which a cooking vessel is placed, and an induction heating coil provided below the cooking plate that generates a magnetic field when an electric current is applied.

[0003] When current is applied to an induction heating coil and a magnetic field is generated, a secondary current is induced in the cooking vessel, and Joule heat is generated due to the electrical resistance component of the cooking vessel itself. The cooking vessel is heated by the Joule heat, and accordingly, the food contained in the cooking vessel is heated.

[0004] Compared to gas ranges that heat cooking vessels using the combustion heat generated by burning fossil fuels, induction heating appliances have a higher heat transfer rate, do not generate harmful gases, and can reduce the risk of fire.

[0005] One aspect of the present disclosure provides a cooking appliance with improved assemblability by laminating the printed circuit board assembly of the cooking appliance using a board-to-board assembly method without wire fastening.

[0006] One aspect of the present disclosure provides a cooking appliance having a shape guide provided to guide the assembly of a printed circuit board assembly of the cooking appliance.

[0029] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the attached drawings.

[0030] FIG. 1 illustrates a cooking apparatus according to one embodiment of the present disclosure. FIG. 2 illustrates a portion of the cooking apparatus according to one embodiment of the present disclosure in isolation.

[0031] Referring to FIGS. 1 and FIGS. 2, the cooking device (1) may include a main body (2) that forms the exterior of the cooking device (1) and on which various parts constituting the cooking device (1) are installed.

[0032] The cooking device (1) may include a cooking plate (10) provided on the upper side of the main body (2). The cooking plate (10) may have a flat shape on which a cooking container can be placed. As an example, the cooking plate (10) may include ceramic glass and / or reinforced glass. For example, the cooking plate (10) may include heat-resistant glass.

[0033] The cooking plate (10) may have various materials. The cooking plate (10) may have the property of not allowing light to pass through. In addition, the cooking plate (10) may have the characteristic of being able to transmit a touch signal to transmit a signal to a circuit board (not shown) provided on the lower side through touch.

[0034] An induction heating coil (20) is housed inside the main body (2) and can generate a magnetic field to induce heating of a cooking vessel. The induction heating coil (20) can be electrically connected to a driving circuit board (40, see FIG. 3) to be described later, which is provided inside the main body (2). The induction heating coil (20) can be electrically connected to the driving circuit board (40, see FIG. 3) in a board-to-board or pin-to-pin manner. The induction heating coil (20) can be located below the cooking plate (10).

[0035] For example, when a driving current is supplied to an induction heating coil (20), a magnetic field can be induced around the induction heating coil (20). In particular, when an alternating current, which changes in magnitude and direction over time, is supplied to the induction heating coil (20), a magnetic field that changes in magnitude and direction over time can be induced around the induction heating coil (20).

[0036] For example, the induction heating coil (20) may include a sheet coil (21) in the shape of a thin substrate. For example, the induction heating coil (20) may include a coil plate (22) provided to have a magnet attached to form a magnetic field below the sheet coil (21).

[0037] The magnetic field around the induction heating coil (20) can pass through the cooking plate (10) made of reinforced glass and reach the cooking container placed on the cooking plate (10).

[0038] Due to a magnetic field that changes in magnitude and direction over time, eddy currents rotating around the magnetic field can be generated in the cooking vessel. This phenomenon, in which eddy currents are generated by a time-varying magnetic field, is called electromagnetic induction. Due to these eddy currents, electrical resistance heat can be generated in the cooking vessel. Electrical resistance heat is the heat generated in a resistor when current flows through it, and is also known as Joule heat. The cooking vessel is heated by this electrical resistance heat, and the food contained within the vessel can be heated.

[0039] When a magnetic field passes through a metal forming a cooking vessel, eddy currents are generated by the resistance of the metal (e.g., iron) of the cooking vessel. The eddy currents generated in the cooking vessel can heat the cooking vessel and heat the food inside.

[0040] In this way, the induction heating coil (20) can heat the cooking vessel using electromagnetic induction and electric resistance heat.

[0041] Cooking vessels may include pots, frying pans, steamers, rice cookers, etc. The types of cooking vessels are not limited to these. In this explanation, a pot will be used as an example.

[0042] The cooking plate (10) may include a cooking zone corresponding to an induction heating coil (20). Multiple induction heating coils (20) corresponding to the cooking zone may be provided. A cooking vessel may be placed in the cooking zone. The cooking zone may be formed on the upper surface of the cooking plate (10). The number and location of the cooking zone are not limited to those shown in this illustration.

[0043] A user interface (11) that receives control commands from a user and displays operation information of the cooking device (1) to the user may be provided on one side of the cooking plate (10). However, the location of the user interface (11) is not limited to the cooking plate (10) and may be provided at various locations, such as the front and / or side of the main body (2). The user interface may include a display unit (11a) and an input unit (11b).

[0044] A circuit board (not shown) for operating the user interface (11) may be provided on the lower side of the user interface (11). The circuit board may include a display and a touch portion.

[0045] The display can be positioned to correspond to the display portion (11a) of the cooking plate (10). The display can indicate whether the cooking vessel is being heated by the induction heating coil (20). Thus, the user can check whether the cooking vessel is being heated through the display portion (11a).

[0046] The touch portion can be positioned to correspond to the input portion (11b) of the cooking plate (10). The touch portion can receive a touch signal from the input portion (11b). For example, the touch portion can receive input using a capacitive touch method. However, it is not limited to this, and the touch portion can also receive input using a pressure-sensitive touch method. The user can control the current flowing through the induction heating coil (20) through the input portion (11b) and determine the degree to which the cooking container is heated.

[0047] An induction heating coil (20) can be mounted on the bracket (30). The bracket (30) may be provided with a plate portion (31) for mounting the induction heating coil (20) and a bent portion (32) provided at the edge of the plate portion (31).

[0048] Below the induction heating coil (20), a printed circuit board assembly may be provided to implement a circuit for supplying a driving current to the induction heating coil (20). The printed circuit board assembly may include a switch element, an integrated circuit element, etc. for supplying a driving current, and a printed circuit board on which these are installed.

[0049] For example, the printed circuit board assembly may include a driving circuit board (40, see FIG. 3) having a driving circuit installed therein that supplies a driving current to an induction heating coil (20), and a power circuit board (60) having a power circuit installed therein that supplies power to the driving circuit.

[0082] In the following description, for the convenience of explanation, configurations that are substantially identical or similar to those described with reference to FIGS. 3 and FIGS. 4 may be omitted or briefly described.

[0083] Referring to FIGS. 7 through 12, the driving circuit board (40) and the power circuit board (60) of a cooking device (1) according to one embodiment of the present disclosure may be arranged to be connected without separate wires. In other words, the driving circuit board (40) and the power circuit board (60) may be arranged to be electrically connected via a board-to-board method or a pin-to-pin method. In other words, the driving circuit board (40) and the power circuit board (60) may be arranged to be stacked vertically and connected to each other.

[0084] The driving circuit board (40) may include a first connector (41) provided to be directly connected to the power circuit board (60).

The first connector (41) and the second connector (62) may be directly connected so that the driving circuit board (40) and the power circuit board (60) are electrically connected.

[0085] As the driving circuit board (40) and the power circuit board (60) are stacked in a vertical direction, the first connector (41) and the second connector (62) can be arranged to be connected in a vertical direction. In other words, the first connector (41) and the second connector (62) can be aligned along the vertical direction and then joined in a vertical direction before being connected so that the driving circuit board (40) and the power circuit board (60) are electrically connected.

[0086] The bracket (30) can be provided so that the driving circuit board (40) and the power circuit board (60) are connected in a horizontal direction.

[0087] For example, in a cooking device (1) according to one embodiment of the present invention, a driving circuit board (40) may be coupled to a power circuit board (60) on the upper side of the power circuit board (60). To this end, a first connector (41) of the driving circuit board (40) may be provided to protrude downward, which is the direction toward the power circuit board (60). A second connector (62) of the power circuit board (60) may be provided to protrude upward, which is the direction toward the driving circuit board (40).

[0088] In other words, the first connector (41) and the second connector (62) can be positioned between the power circuit board (60) and the driving circuit board (40). Accordingly, when the power circuit board (60) and the driving circuit board (40) are combined through stacking, the user cannot directly check the first connector (41) and the second connector (62). Therefore, the bracket (30) may include a guide bush (35) and a bending part (32) to guide the first connector (41) and the second connector (62) to be aligned in a vertical direction.

[0089] The guide bush (35) and the bending portion (32) of the bracket (30) are connected to the guide projection (75) of the holder (70) and the side wall (72) of the main body (2), thereby guiding the position of the first connector (41) to be aligned vertically with the second connector (62).

[0090] A guide bush (35) may be disposed on the lower surface of the bracket (30). Multiple guide bushes (35) may be provided. A driving circuit board (40) may be disposed on the lower surface of the bracket (30). The driving circuit board (40) may include a through hole (45) through which the guide bush (35) passes. The through hole (45) of the driving circuit board (40) may be provided at a position corresponding to the guide bush (35).

[0091] Accordingly, the driving circuit board (40) can be arranged to be fixed to the bracket (30). Accordingly, the position of the first connector (41) can be arranged to be fixed relative to the guide bush (35). The protrusion direction of the first connector (41) can be arranged to be the same as the protrusion direction of the guide bush (35).

[0092] A guide projection (75) may be disposed on the upper surface of the holder (70). A plurality of guide projections (75) may be provided. A power circuit board (60) may be disposed on the upper surface of the holder (70). The power circuit board (60) may include a through hole (65) provided to allow the guide projection (75) to pass through. The through hole (65) of the power circuit board (60) may be provided at a position corresponding to the guide projection (75). The protrusion direction of the second connector (62) may be provided to be the same as the protrusion direction of the guide projection (75).

[0093] Accordingly, the power circuit board (60) can be arranged to be fixed to the holder (70). Accordingly, the position of the second connector (62) can be arranged to be fixed relative to the guide projection (75).

[0094] Accordingly, a cooking device (1) according to one embodiment of the present disclosure may be configured such that when a guide bush (35) is connected to a guide projection (75), a first connector (41) fixed in a position relative to the guide bush (35) and a second connector (62) fixed in a position relative to the guide projection (75) are coupled. In other words, the first connector (41) may be configured to be aligned along a vertical direction with the second connector (62) through the guide bush (35) and the guide projection (75).

[0095] The guide projection (75) may be provided to be coupled with the guide bush (35). Specifically, the guide projection (75) may be provided to receive the end of the guide bush (35). The guide projection (75) may include a hollow (76) formed vertically inside. The end of the guide bush (35) may be inserted into the hollow (76) of the guide projection (75) so that the guide projection (75) and the guide bush (35) are connected.

[0096] The diameter of the hollow (76) can be made to be the same as that of the guide bush (35). Accordingly, the guide bush (35) can be accommodated in the hollow (76). Accordingly, the outer diameter of the guide projection (75) can be made to be larger than the diameter of the guide bush (35).

[0097] The upper portion of the inner surface of the guide projection (75) may be provided to be chamfered. In other words, the guide projection (75) may include an inclined surface (78) formed on the upper inner surface. The inclined surface (78) may be provided to be inclined downward as it approaches the central axis of the guide projection (75).

[0098] Accordingly, the guide projection (75) can be arranged so that the guide bush (35) is inserted even if it is not accurately aligned along the vertical direction with respect to the guide bush (35).
