[0022] Hereinafter, cooking devices according to various embodiments will be described in detail with reference to the drawings.

[0023] FIG. 1 is a drawing showing a cooking device (100) according to at least one embodiment of the present disclosure.

[0024] The cooking device (100) is a variety of electronic devices that can be used for cooking, such as a gas stove, microwave oven, induction cooktop, oven, air fryer, toaster, and grill. Recently, smart cooking devices that integrate the functions of these various types of electronic devices into one are also being developed and distributed.

[0025] Although an induction cooktop is illustrated as one example in FIG. 1, the various embodiments described below are not necessarily limited to induction cooktops and can be implemented in various types of cooking devices. Furthermore, the various embodiments of the present disclosure may be implemented in various types of electronic devices, such as washing machines, refrigerators, and air conditioners, in addition to cooking devices. Although the following description is based on an induction cooktop, it will be described using a cooking device (100) that is not an induction cooktop.

[0026] In the present disclosure, the cooking device (100) is a device that cooks food using heat generated by using power generated by an induction current. In addition, such a cooking device (100) may be referred to as an induction, an induction range, an induction cooktop, an induction heating cooking means, etc. In the present disclosure, the cooking device (100) may be a device that cooks food using heat generated by an induction current.

[0027] The upper surface of the cooking device (100) may be referred to as a heating section. The surface of the heating section may be provided in the form of a flat plate. The cooking device (100) of the induction heating method generates a magnetic field by applying current to an induction heating coil, and an induction-specific cooking vessel placed on the upper side of the induction heating coil can be heated by electrical resistance caused by eddy current generated by the magnetic field. Such an induction heating coil may also be referred to as a sheet coil, and a module including at least one sheet coil may be referred to as an induction module.

[0028] The cooking device (100) may include a main body (10), a display (20a), and a speaker structure (1000).

[0029] The main body (10) of the cooking device (100) is configured to accommodate various components, including at least one induction module. The main body may also be described as a housing, a case, etc.

[0030] The main body (10) may have a glass (10a) or a plate made of other material on which a container can be placed on the upper surface. The glass (10a) is a part that forms the upper surface of the main body (10). At least one induction module (not shown) and a control panel (20), etc., may be placed on the lower side of the glass (10a). The glass (10a) may be formed of a heat-resistant glass plate. The glass (10a) can stably support the cooking container and allow heat generated from the induction coil to be transferred from the bottom to the top.

[0031] The induction module may be composed of multiple sheet coils (not shown).

[0032] Each of the plurality of sheet coils (not shown) can heat the container in the manner described above when an electric signal is applied while the container is placed on the upper surface. The number of the plurality of sheet coils (not shown) arranged inside the main body (10) of FIG. 1 can be determined in various ways depending on the size of the cooking device (100).

[0033] Each of the multiple sheet coils (not shown) may include a plurality of sensor coils (not shown). Each of the multiple sensor coils (not shown) is configured to detect a container on the upper side. The number of sensor coils may vary depending on the size of the sheet coil. For example, one sensor coil may be placed for a single sheet coil, or two or more sensor coils may be used. Each sensor coil may be distributed so that containers can be detected at multiple locations within a single sheet coil. For example, if four sensor coils are used within a single sheet coil, the four sensor coils may be placed one at each corner of the sheet coil.

[0034] The main body (10) may be divided into multiple regions. A display (20a) may be placed in some of the multiple regions, and the aforementioned sheet coils may be placed in the remaining regions. When the position of the container moves to another region during cooking, the cooking device (100) may drive the sheet coil in the other region and turn off the sheet coil in the region where the container was previously located.

[0035] A Printed Board Assembly (PBA) may be placed below a plurality of sheet coils within the main body (10). The PBA serves as an electronic circuit of the cooking device (100) and can control the current and frequency of the plurality of sheet coils. Additionally, the PBA can control the overall operating state of the cooking device (100).

[0036] The display (20a) is configured to display various screens under the control of the processor. The display (20a) may be configured as part of the control panel (20). As the control panel (20) is coupled to the lower side of the glass (10a), the display (20a) can show a screen on the upper side of a portion of the entire area of ​​the glass (10a).

[0037] The display may be implemented as a general display including light-emitting elements such as LCD or LED, or as a touch screen with a built-in touch sensor. When implemented as a touch screen, the display (20a) may function as a user interface. For example, the display (20a) may display various buttons or menus for controlling the operation of the cooking device (100).

[0038] Although the display (20a) is shown in FIG. 1 as being placed in an area of ​​the upper surface of the cooking device (100), if the cooking device (100) is not built into a sink or furniture, the display (20a) may be placed on the front side of the cooking device (100). In addition, although not shown in FIG. 1, the cooking device (100) may additionally be equipped with various buttons for performing operations separately from the display (20a).

[0039] The cooking device (100) can check the position of a cooking container using a provided sensor and perform a cooking operation by operating a heating coil corresponding to the confirmed position. Additionally, if the cooking container is located in an outer area, the cooking device (100) can display a message on the control panel (20) requesting the cooking container to be moved to the cooking area. Here, the outer area is the area between the outermost heating coil among the plurality of heating coils and the outer area of ​​the cooking device (100). This outer area may be referred to as a non-cooking area, edge area, prohibited area, non-heating area, danger area, etc. The cooking area is the upper area of ​​the cooking device (100) excluding the aforementioned outer area, and may be referred to as a coil area, inner area, heating area, magnetic induction area, container placement area, etc.

[0040] A speaker structure (1000) is a device that generates a physical acoustic signal by vibrating air through a diaphragm using an electrical signal. The speaker structure (1000) can process various frequency bands depending on the characteristics of the device. For example, the speaker structure (1000) can be formed as a woofer that processes a low frequency band, a mid-range that processes a mid-frequency band, or a tweeter that processes a high frequency band. However, it is not necessarily limited to these and can be formed as various speakers that process frequency bands.

[0041] The speaker structure (1000) can output an alert sound or an alert message. For example, the speaker structure (1000) can output information about the current state of the cooking device (100). And if it is a dangerous state, the speaker structure (1000) can output information about the dangerous state. This dangerous state may be when a cooking vessel is located on the control panel or the outer edge, or when a cooking vessel is not located but the temperature of the cooking area is above a certain temperature. Additionally, it may be when multiple cooking vessels are located on a single heating coil.

[0042] Additionally, when the control operation (or heating state) changes according to a change in the cooking state, the speaker structure (1000) can output information about this. For example, when heating is completed (e.g., boiling of the soup occurs) during soup cooking, and the operating state of the heating device changes from a high state to an intermediate state while maintaining a constant temperature, the speaker structure (1000) can output a sound indicating that the heating intensity has changed. As described above, the cooking device (100) according to the present embodiment can identify cases where the cooking container is located in a dangerous area and can provide a notification regarding such cases, thereby increasing safety. The speaker structure (1000) is directly or indirectly coupled to the lower surface of the glass (10a) and can output various sound signals in the downward direction of the main body (10). To this end, the lower space of the speaker device in the main body (10) may be in a shape exposed to the outside.

[0043] A detailed description of the speaker structure (1000) will be provided later, so the description thereof is omitted.

[0044] FIG. 2 is a drawing showing the lower surface of a cooking device (100) according to one or more embodiments of the present disclosure.

[0045] The cooking device (100) may include a main body (10), a control panel (20), at least one induction module (30), and a speaker structure (1000).

[0046] In FIG. 2, at least one induction module (30) may be accommodated in the main body (10). The at least one induction module (30) may include various components, including a plurality of sheet coils. Alternatively, the at least one module (30) may be referred to as an induction heating device (30) that includes a heating coil used to heat a cooking vessel placed on top of the glass, which is accommodated in the main body (10) on the lower side of the glass. For example, it may include various components such as a plurality of sheet coils and a plurality of sensor coils. Since the description of the plurality of sheet coils and the plurality of sensor coils has been described above, the description thereof is omitted.

[0047] In FIG. 2, a speaker structure (1000) may be placed on the lower surface of a glass (10a). Here, the glass (10a) refers to a configuration arranged to cover at least one induction module (30) and a control panel (20) on the upper surface of the main body (10). Additionally, the control panel (20) may be placed on the lower surface of the glass (10a). The speaker structure (1000) may be directly connected to the lower surface of the glass (10a) or indirectly connected through a part of the structure of the control panel (20). In the present disclosure, the speaker structure (1000) being connected to the lower surface of the glass (10a) includes not only direct connection but also indirect connection in which a part of the structure intervenes in between. As shown in FIG. 2, the control panel (20) and the speaker structure (1000) may be exposed on the lower surface of the cooking device (100). That is, the space in the lower structure of the main body (10) where the speaker structure (1000) and the control panel (20) are formed can be configured as an empty space. Accordingly, since the lower side of the speaker structure (1000) is exposed, the acoustic signal output from the speaker structure (1000) downward can be transmitted to the outside more effectively.

[0048] Additionally, as the control panel (20) is positioned on the lower surface of the glass (10a), the screen displayed on the display (20a), which is part of the control panel (20), can be seen through a part of the glass (10a). When a user touches the screen of the display (20a) on the glass (10a), the control panel (20) may identify the touch point and recognize the menu selected by the user.

[0049] Specifically, the control panel (20) may include an operating part (21) and an attachment part (22). The operating part (21) is a device capable of performing and controlling various operations of the cooking device (100). Various components necessary for operating the cooking device (100) may be arranged within the operating part (21). For example, a display (20a), a touch sensor, a processor, or a memory may be mounted on the operating part (21). The attachment part (22) may be formed integrally with the operating part (21) or assembled and fixed.

[0050] The attachment portion (22) may be formed by extending in the peripheral direction of the operating portion (21). The attachment portion (22) may be attached to the glass (10a) placed on the upper surface. For example, the attachment portion (22) may be bonded to the glass (10a) through a bonding member. Alternatively, it may be combined with a groove, protrusion, etc. formed on the lower surface of the glass (10a).

[0051] In the cooking device (100) of FIG. 2, a fan (not shown) may be positioned on the opposite side of the speaker structure (1000) and the control panel (20). That is, the fan (not shown) may be positioned on the front lower surface of the cooking device (100). Alternatively, the speaker structure (1000) may be positioned on the rear lower surface of the cooking device (100). If the speaker structure (1000) is positioned on one side of the control panel (20) as in FIG. 1 and FIG. 2, the fan may be positioned on the opposite side of the main body (10) of the cooking device (100) relative to the position of the control panel (20).

[0052] The speaker structure (1000) can be separated from the noise of the fan (not shown) by being spaced apart from the location of the noise-generating fan (not shown). Additionally, the speaker structure (1000) can be positioned near the control panel (20) or below the control panel (20), thereby being positioned close to the user. Accordingly, the speaker structure (1000) can deliver accurate sound to the user.

[0053] The details regarding the attachment of the speaker structure (1000) to the attachment part (22) will be explained in detail in FIG. 3.

[0054] FIG. 3 is an enlarged view of the speaker mounting part (1200) and speaker device (1100) in FIG. 2.
