The first baffle is positioned between the fan and the display area to prevent airflow from the fan from reaching the display area. Simultaneously, a second baffle is located at the notch, fixed to either the lower cover or the circuit board, and positioned between the display area and the main control area of ​​the circuit board. This second baffle prevents airflow from the fan from reaching the display area via the notch. Thus, the first and second baffles work together to prevent airflow from the fan from reaching the display area. Furthermore, the first baffle is positioned on the lower cover, and the second baffle is positioned on either the lower cover or the circuit board. This design allows for clear mounting of the induction cooker during assembly. By observing the placement of the first and second baffles and the circuit board on the lower cover, the relative positions of the first and second baffles and the digital tubes, LED lights, touch springs, and other electrical components in the display area of ​​the circuit board are ensured to be accurate. During the use of the induction cooker, the first and second baffles work together to effectively block the oil fumes drawn in by the fan, achieving a good oil fume isolation effect. This prevents oil fumes from blowing onto the display area, causing unclear display of the digital tubes or LED lights, or unresponsive touch buttons. This effectively solves the problem of existing induction cookers where the upper cover's wind deflector deforms significantly during lid assembly, shifting towards the LED lights or digital tubes, leading to interference between the wind deflector and the LED lights or digital tubes after lid assembly, resulting in inaccurate wind deflector positioning and poor oil fume isolation.

Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more particularly to an induction cooker. Background Technology

[0002] In order to reduce production costs, some existing induction cookers have integrated the originally separate display board and main control board into a single circuit board, that is, the integrated circuit board has both a display area and a main control area. For example, patent CN212339327U discloses an induction cooker, which includes a shell formed by the snap-fitting of an upper cover and a lower cover. A control board is set inside the shell. The control board includes a display control area (i.e., the display area) and a power control area (i.e., the main control area) set on the same substrate.

[0003] The display area typically contains electronic components such as digital tubes, LED lights, and touch springs. To prevent the fumes drawn in by the fan from the air inlet during the use of the induction cooker from blowing onto these components and causing them to become unclear or the touch buttons to become unresponsive, a baffle is usually designed on the top cover of the induction cooker to block the fumes.

[0004] However, the wind deflector ribs on the top cover are quite long, and the top cover itself is easily deformed. When the top cover is glued to the panel and then assembled with the bottom cover, the deformation of the wind deflector ribs inside cannot be seen. If the wind deflector ribs are deformed significantly during assembly, they may deviate towards the LED light or digital tube, causing interference between the wind deflector ribs and the LED light or digital tube after assembly. This results in the wind deflector ribs not blocking the smoke accurately and thus failing to effectively isolate the oil fumes. Utility Model Content

[0005] To address the problem that the baffle ribs on the top cover of an induction cooker deform significantly during assembly, causing them to deviate towards the LED light or digital display, which in turn leads to interference between the baffle ribs and the LED light or digital display after assembly, resulting in inaccurate baffle rib positioning and poor smoke isolation, this application provides an induction cooker.

[0006] This application provides an induction cooker, including a lower cover and an upper cover covering the lower cover. The lower cover is provided with a circuit board and a fan. The circuit board includes a display area and a main control area disposed on the same substrate. The fan is used to blow air onto the main control area.

[0007] The lower cover is provided with a first baffle, and a placement notch is formed between the first baffle and one side edge of the lower cover. The circuit board is installed on the lower cover through the placement notch, and the first baffle is disposed between the fan and the display area. A second baffle is provided at the placement notch. The second baffle is fixed to one of the lower cover and the circuit board and is disposed between the display area and the main control area, so as to block the air blown by the fan from blowing towards the display area together with the first baffle.

[0008] In some embodiments, the lower cover is provided with a surrounding panel that surrounds the periphery of the fan, the surrounding panel having an opening facing the main control area, and the first baffle is formed by extending from the open end of the surrounding panel.

[0009] In some embodiments, the lower cover has opposing first and second side edges, the enclosure is disposed adjacent to the first side edge, the first baffle is formed by extending the open end of the enclosure toward the second side edge, and the second baffle is disposed between the first baffle and the second side edge.

[0010] In some embodiments, the second baffle is mounted above the circuit board at the placement notch, with one end of the second baffle connected to the first baffle and the other end of the second baffle extending to one side edge of the lower cover.

[0011] In some embodiments, a portion of the second baffle is located above the circuit board, and the bottom of the second baffle forms a clearance step with the corresponding area above and below the circuit board.

[0012] And / or, the circuit board has a strip groove in the area corresponding to the upper and lower parts of the second baffle, so as to increase the creepage distance between the electrical components in the display area and the electrical components in the main control area.

[0013] In some embodiments, the second baffle is mounted above the circuit board at the placement notch. The second baffle is provided with a connecting post, and the lower cover is provided with a connecting hole. The second baffle is fixed to the lower cover by fasteners passing through the connecting post and the connecting hole.

[0014] In some embodiments, the second baffle has a first end and a second end opposite to each other, the first end and the second end of the second baffle are respectively provided with the connecting post, the lower cover is provided with mounting posts corresponding to the connecting posts, and the mounting posts are provided with the connecting holes.

[0015] In some embodiments, the second baffle is mounted above the placement notch on the circuit board, and the bottom of the second baffle is provided with a connecting rib. The circuit board is provided with a connecting groove, and the connecting rib is inserted into the connecting groove so that the second baffle is fixed on the circuit board.

[0016] In some embodiments, there are multiple insertion ribs, which are spaced apart at the bottom of the second baffle, and the number of insertion slots is equal to the number of insertion ribs and they are arranged in a one-to-one correspondence.

[0017] Alternatively, the insertion rib is a strip rib extending in the same direction as the second baffle, and the insertion groove is a strip groove adapted to the shape of the insertion rib, the strip groove being disposed between the display area and the main control area.

[0018] In some embodiments, the second baffle is fixed to the lower cover, and the circuit board is mounted on the lower cover from above the second baffle. The circuit board has a hollow groove corresponding to the second baffle, and the upper part of the second baffle passes through the hollow groove and extends to the upper area of ​​the circuit board.

[0019] The technical solution provided in this application has at least the following advantages compared with the prior art:

[0020] The induction cooker provided in this application features a first baffle on the lower cover, with a notch formed between the first baffle and one edge of the lower cover to allow the circuit board to be mounted on the lower cover via the notch. The first baffle is positioned between the fan and the display area to prevent airflow from the fan from reaching the display area. Simultaneously, a second baffle is located at the notch, fixed to either the lower cover or the circuit board, and positioned between the display area and the main control area of ​​the circuit board. This second baffle prevents airflow from the fan from reaching the display area via the notch. Thus, the first and second baffles work together to prevent airflow from the fan from reaching the display area. Furthermore, the first baffle is positioned on the lower cover, and the second baffle is positioned on either the lower cover or the circuit board. This design allows for clear mounting of the induction cooker during assembly. By observing the placement of the first and second baffles and the circuit board on the lower cover, the relative positions of the first and second baffles and the digital tubes, LED lights, touch springs, and other electrical components in the display area of ​​the circuit board are ensured to be accurate. During the use of the induction cooker, the first and second baffles work together to effectively block the oil fumes drawn in by the fan, achieving a good oil fume isolation effect. This prevents oil fumes from blowing onto the display area, causing unclear display of the digital tubes or LED lights, or unresponsive touch buttons. This effectively solves the problem of existing induction cookers where the upper cover's wind deflector deforms significantly during lid assembly, shifting towards the LED lights or digital tubes, leading to interference between the wind deflector and the LED lights or digital tubes after lid assembly, resulting in inaccurate wind deflector positioning and poor oil fume isolation.

[0039] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0041] Reference Figures 1 to 8As shown, some embodiments of this application provide an induction cooker, which includes a lower cover 1 and an upper cover 2 covering the lower cover 1. The lower cover 1 is provided with a circuit board 3 and a fan 4. The circuit board 3 includes a display area 31 and a main control area 32 disposed on the same substrate. The fan 4 is used to blow air onto the main control area 32.

[0042] In other words, the same circuit board 3 serves as both the display area 31 and the main control area 32. Essentially, the display board and main control board of the induction cooker are integrated into a single circuit board to reduce production costs. Specifically, the display area 31 typically contains electronic components such as a digital tube 311, an LED light 312, and a touch spring 313. The main control area 32 typically contains electronic components such as power transistors and rectifier bridges. These components generate a significant amount of heat during operation, which is dissipated by blowing air onto the main control area 32 using a fan 4. Furthermore, to further dissipate heat from the electronic components in the main control area 32, a heat sink 321 can be installed in the main control area 32 of the circuit board 3 to quickly conduct heat away.

[0043] The lower cover 1 is provided with a first baffle 11, and a placement notch 12 is formed between the first baffle 11 and one side edge of the lower cover 1. The circuit board 3 is installed on the lower cover 1 through the placement notch 12, and the first baffle 11 is separated between the fan 4 and the display area 31. A second baffle 5 is provided at the placement notch 12. The second baffle 5 is fixed on one of the lower cover 1 and the circuit board 3, and is separated between the display area 31 and the main control area 32, so as to block the air blown by the fan 4 from blowing towards the display area 31 together with the first baffle 11.

[0044] The induction cooker provided in this application embodiment has a first baffle 11 on the lower cover 1, and a placement notch 12 is formed between the first baffle 11 and one side edge of the lower cover 1 so that the circuit board 3 can be installed on the lower cover 1 through the placement notch 12. The first baffle 11 is disposed between the fan 4 and the display area 31 to block the air blown by the fan 4 from blowing towards the display area 31. At the same time, a second baffle 5 is provided at the placement notch 12. The second baffle 5 is fixed to one of the lower cover 1 and the circuit board 3, and is disposed between the display area 31 and the main control area 32 of the circuit board 3 to block the air blown by the fan 4 from blowing towards the display area 31 through the placement notch 12. Thus, the first baffle 11 and the second baffle 5 jointly block the air blown by the fan 4 from blowing towards the display area 31.

[0045] Furthermore, the first baffle 11 is mounted on the lower cover 1, and the second baffle 5 is mounted on the lower cover 1 or the circuit board 3. This allows the positions of the first baffle 11, the second baffle 5, and the circuit board 3 on the lower cover 1 to be clearly visible during the assembly of the induction cooker. This ensures the accurate relative positions of the digital tube 311, LED light 312, touch spring 313, and other electrical components in the display area 31 of the circuit board 3, ensuring that the first baffle 11, the second baffle 5, and the circuit board 3's display area are correctly positioned. This also allows the induction cooker to operate smoothly during use, utilizing the combined forces of the first baffle 11 and the second baffle 5. It effectively blocks the oil fumes sucked in by the fan 4, achieving a good effect of isolating oil fumes and preventing oil fumes from blowing onto the display area 31, causing the digital tube 311 or LED light 312 of the display area 31 to be unclear, or the touch buttons to be unresponsive. This effectively solves the problem that when the lid of the existing induction cooker is assembled, the wind baffle of the lid deforms greatly and deviates towards the LED light or digital tube, which leads to interference between the wind baffle and the LED light or digital tube after the lid is assembled, resulting in inaccurate blocking position of the wind baffle and poor oil fume isolation effect.

[0046] It should be noted that, since the circuit board 3 is an integrated circuit board that combines the display area 31 and the main control area 32, in order to assemble the integrated circuit board on the lower cover 1, a baffle extending from one edge of the lower cover 1 to the other opposite edge cannot be directly formed on the lower cover 1. Therefore, the induction cooker provided in this embodiment of the application has a first baffle 11 and a second baffle 5 on the lower cover 1, so that the first baffle 11 and the second baffle 5 together block the air blown by the fan 4 from blowing towards the display area 31.

[0047] The first baffle 11 can be directly formed on the lower cover 1. For example, the first baffle 11 can be directly formed on the lower cover 1 during injection molding. Of course, the first baffle 11 can also be an independent component and fixed on the lower cover 1 by means of bonding or other methods. Furthermore, a placement notch 12 is formed between the first baffle 11 and one side edge of the lower cover 1 so that the circuit board 3 can be assembled onto the lower cover 1 through the placement notch 12.

[0048] The second baffle 5 can be a separate component. After the circuit board 3 is assembled onto the lower cover 1, the second baffle 5 is installed at the placement notch 12 and positioned between the display area 31 and the main control area 32 of the circuit board 3. This allows the first baffle 11 and the second baffle 5 to jointly block the air blown by the fan 4 from reaching the display area 31. It should be understood that in specific implementations, the fan 4 and the main control area 32 are located on the same side of the first baffle 11 and the second baffle 5, while the display area 31 is located on the other side of the first baffle 11 and the second baffle 5. This ensures that the air blown by the fan 4 reaches the main control area 32, while minimizing the air blown towards the display area 31.

[0049] Of course, the second baffle 5 can also be directly formed on the lower cover 1. For example, the second baffle 5 can be directly formed on the lower cover 1 during injection molding. However, a gap needs to be set between the first baffle 11 and the second baffle 5. That is, the second baffle 5 cannot completely block the placement notch 12 to ensure that the circuit board 3 can be assembled on the lower cover 1 through the placement notch 12. Specifically, refer to Figures 6 to 8 As shown, a cutout groove 33 can be made on the circuit board 3 at the location corresponding to the second baffle 5, so that the upper part of the second baffle 5 passes through the cutout groove 33 and extends to the upper area of ​​the circuit board 3, so that the upper part of the second baffle 5 is separated between the display area 31 and the main control area 32.

[0050] During assembly, the first baffle 11, the second baffle 5, and the circuit board 3 can be installed or mounted on the lower cover 1. Components such as the fan 4, coil 7, and power cord 8 can also be mounted on the lower cover 1. A panel 6 is mounted on the upper cover 2, which can be bonded to the panel 6. After the upper cover 2 and panel 6 are assembled, they are then closed and assembled with the lower cover 1. Since the first baffle 11 and the second baffle 5 are accurately fixed to the lower cover 1 or the circuit board 3 when the upper cover 2 and lower cover 1 are closed, the assembly is stable and not easily deformed. Therefore, after the upper cover 2 and lower cover 1 are closed, the relative positions of the electrical components in the display area 31 of the circuit board 3 and the first baffle 11, the second baffle 5, and the circuit board 3 can be accurately ensured, thereby improving the effect of using the first baffle 11 and the second baffle 5 to isolate oil fumes.

[0051] In addition, the first baffle 11 and / or the second baffle 5 can be made of heat insulation board to reduce the heat generated by the electrical components of the main control area 32 during operation and transfer to the display area 31.

[0052] In some embodiments, refer to Figures 1 to 3 , Figure 6 and Figure 7 As shown, the lower cover 1 is provided with a surrounding plate 13 surrounding the fan 4. The surrounding plate 13 has an opening facing the main control area 32, and the first baffle 11 is formed by extending from the open end of the surrounding plate 13.

[0053] With the above arrangement, the air blown out by the fan 4 is guided by the enclosure 13, so that more of the air blown out by the fan 4 is blown towards the main control area 32 through the open area of ​​the enclosure 13; the open end of the enclosure 13 extends to form a first baffle 11 between the fan 4 and the display area 31, so that the air blown out by the fan 4 flows along the first baffle 11 away from the surface of the display area 31, and blows towards the display area 31 as little as possible.

[0054] Continue to refer to Figures 1 to 3 , Figure 6 and Figure 7As shown, the lower cover 1 has a first side edge 14 and a second side edge 15 opposite to each other, the surrounding plate 13 is disposed opposite to the first side edge 14, the first baffle 11 is formed by extending the open end of the surrounding plate 13 toward the second side edge 15, and the second baffle 5 is disposed between the first baffle 11 and the second side edge 15.

[0055] For example, refer to Figure 2 As shown in the diagram, the double-headed arrow XX points in the direction of the induction cooker's width. (Refer to...) Figure 3 and Figure 7 As shown, the lower cover 1 has a first side edge 14 and a second side edge 15 that are opposite each other along the width direction of the induction cooker.

[0056] With the above arrangement, the enclosure 13, the first baffle 11, and the second baffle 5 together form a partition structure extending from the first side edge 14 to the second side edge 15 of the lower cover 1, thereby effectively blocking the wind blown out by the fan 4 and improving the wind blocking effect.

[0057] In some embodiments, refer to Figures 1 to 5 As shown, the second baffle 5 is installed above the circuit board 3 at the placement notch 12, and one end of the second baffle 5 is connected to the first baffle 11, while the other end of the second baffle 5 extends to one side edge of the lower cover 1.

[0058] With the above settings, the second baffle 5 can effectively block the placement notch 12, thereby improving the windproof effect. Furthermore, the second baffle 5 is installed at the placement notch 12 from the upper area of ​​the circuit board 3. During assembly, the circuit board 3 is first installed on the lower cover 1, and then the second baffle 5 is installed on the lower cover 1 or the circuit board 3 to ensure that the second baffle 5 does not affect the normal assembly of the circuit board 3 on the lower cover 1.

[0059] It should be understood that, in order to achieve the blocking effect, the extension length of the second baffle 5 can be greater than or equal to the width of the corresponding upper and lower portions of the second baffle 5 on the circuit board 3. That is, a portion of the second baffle 5 can extend beyond the circuit board 3. To enable the second baffle 5 to be mounted on the lower cover 1 and to allow the second baffle 5 to block between the display area 31 and the main control area 32 of the circuit board 3, in some embodiments, refer to... Figure 1 , Figure 4 and Figure 5 As shown, a portion of the second baffle 5 is located above the circuit board 3, and the bottom of the second baffle 5 forms a clearance step 51 with the corresponding area of ​​the circuit board 3. Simultaneously, to ensure the blocking effect, the bottom of the second baffle 5, with the corresponding area of ​​the circuit board 3, can be attached to the upper surface of the circuit board 3, and the area of ​​the second baffle 5 extending out of the bottom of the circuit board 3 can be attached to the surface of the lower cover 1.

[0060] To enhance electrical safety, in some embodiments, the circuit board 3 has a strip-shaped groove in the area corresponding to the upper and lower parts of the second baffle 5. This groove increases the creepage distance between the electrical components in the display area 31 and the electrical components in the main control area 32, thereby improving electrical safety. Furthermore, since the strip-shaped groove is located below the second baffle 5, it can be effectively shielded by the second baffle 5.

[0061] In some embodiments, refer to Figures 1 to 5 As shown, the second baffle 5 is mounted above the circuit board 3 at the placement notch 12. The second baffle 5 has a connecting post 52, and the lower cover 1 has a connecting hole 16. The second baffle 5 is fixed to the lower cover 1 by fasteners 18 passing through the connecting post 52 and the connecting hole 16. Using fasteners 18 to fix the second baffle 5 to the lower cover 1 simplifies the fixing structure and facilitates assembly. Specifically, the fasteners 18 can be screws.

[0062] Continue to refer to Figures 1 to 5 As shown, the second baffle 5 has a first end and a second end, and the first end and the second end of the second baffle 5 are respectively provided with connecting posts 52. The lower cover 1 is provided with mounting posts 17 that correspond one-to-one with the connecting posts 52, and the mounting posts 17 are provided with connecting holes 16.

[0063] In a specific implementation, the first and second ends of the second baffle 5 can be located on both sides of the circuit board 3, so that the first and second ends of the second baffle 5 are both set away from the circuit board 3. The lower cover 1 is provided with mounting posts 17 located on both sides of the circuit board 3. The mounting posts 17 are provided with connecting holes 16. The second baffle 5 is installed at the placement notch 12 from the upper area of ​​the circuit board 3, and the connecting posts 52 at both ends of the second baffle 5 correspond to the mounting posts 17 located on both sides of the circuit board 3 on the lower cover 1. The connecting posts 52 are provided with through holes. Fasteners 18 (such as screws) pass through the through holes on the connecting posts 52 and are fastened to the connecting holes 16 on the mounting posts 17. In this way, the second baffle 5 is fixed on the lower cover 1, and the second baffle 5 is used to separate the display area 31 and the main control area 32 of the circuit board 3 to play a blocking role.

[0064] To ensure the connection and blocking effect between the second baffle 5 and the first baffle 11, one of the two mounting posts 17 is arranged adjacent to the first baffle 11, and the height of the mounting post 17 is slightly lower than the height of the first baffle 11. A snap-fit ​​notch is formed on the side wall of the connecting post 52 on the second baffle 5 that is relatively close to the first baffle 11. The connecting post 52 corresponds vertically to the mounting post 17, and the connecting post 52 can be snapped into the side of the first baffle 11 that is relatively close to the second baffle 5 through the snap-fit ​​notch, thereby realizing the firm connection between the second baffle 5 and the first baffle 11, which not only ensures the stability of the connection, but also improves the blocking effect of the blocking structure formed by the two together.

[0065] Of course, the second baffle 5 is not limited to being fixed to the lower cover 1 by fastener 18; it can also be fixed to the lower cover 1 by other methods such as snap-fit. Furthermore, it can be fixed to the circuit board 3 by plugging in. In some embodiments, the second baffle 5 is mounted on the upper part of the circuit board 3 at the placement notch 12. The bottom of the second baffle 5 is provided with a connecting rib (not shown), and the circuit board 3 is provided with a connecting groove. The connecting rib is inserted into the connecting groove to fix the second baffle 5 to the circuit board 3. With this configuration, compared to the fastener 18 connection method, only the connecting rib at the bottom of the second baffle 5 needs to be inserted into the connecting groove on the circuit board 3, making the assembly operation more convenient.

[0066] In practice, multiple connectors can be used, spaced apart at the bottom of the second baffle 5. The number of connector slots is equal to the number of connectors and they are arranged in a one-to-one correspondence. This arrangement ensures the second baffle 5 is securely fixed to the circuit board 3 by the interlocking of multiple connectors with their corresponding slots.

[0067] Of course, the number of connecting ribs is not limited to multiple; the connecting ribs can also be strip-shaped ribs extending in the same direction as the second baffle 5, and the connecting groove is a strip-shaped groove adapted to the shape of the connecting rib, with the strip-shaped groove positioned between the display area 31 and the main control area 32. This arrangement ensures the second baffle 5 is firmly fixed to the circuit board 3 by utilizing the interlocking fit between the longer strip-shaped connecting ribs and the strip-shaped connecting groove. Furthermore, the strip-shaped groove can increase the creepage distance between the electrical components in the display area 31 and the electrical components in the main control area 32, thereby improving electrical safety.

[0068] In some embodiments, refer to Figure 1 and Figure 2As shown, the circuit board 3 can be L-shaped as a whole. The display area 31 of the circuit board 3 extends along the width direction of the induction cooker, that is, the display area 31 of the circuit board 3 extends from the first side edge 14 of the lower cover 1 towards the second side edge 15. The main control area 32 of the circuit board 3 extends perpendicular to the width direction of the induction cooker, so that the main control area 32 and the display area 31 form an angle. The first baffle 11 is positioned between the side edge of the display area 31 that is relatively close to the main control area 32 and the fan 4. One end of the second baffle 5 is connected to the first baffle 11. A part of the second baffle 5 is positioned at the side edge of the display area 31 that is relatively close to the main control area 32, and the other part of the second baffle 5 is positioned between the display area 31 and the main control area 32, so that the first baffle 11 and the second baffle 5 together form a partition structure. The fan 4 and the main control area 32 are located on one side of the first baffle 11 and the second baffle 5, and the display area 31 is located on the other side of the first baffle 11 and the second baffle 5, thereby achieving a good effect of isolating oil fumes.

[0069] In other embodiments, reference is made to Figures 6 to 8 As shown, the second baffle 5 is fixed on the lower cover 1, and the circuit board 3 is installed on the lower cover 1 from above the second baffle 5. The circuit board 3 is provided with a hollow groove 33 corresponding to the second baffle 5. The upper part of the second baffle 5 passes through the hollow groove 33 and extends to the upper area of ​​the circuit board 3.

[0070] Specifically, the second baffle 5 can be directly formed on the lower cover 1. For example, the second baffle 5 can be formed directly on the lower cover 1 during injection molding. Of course, the second baffle 5 can also be an independent component, fixed to the lower cover 1 by bonding or other means. In order to realize the installation of the circuit board 3 on the lower cover 1, a hollow groove 33 is opened in the area of ​​the circuit board 3 corresponding to the upper and lower areas of the second baffle 5, so that the upper part of the second baffle 5 passes through the hollow groove 33 and extends to the upper area of ​​the circuit board 3, so as to block the wind between the display area 31 and the main control area 32.

[0071] In a specific implementation, the second baffle 5 extends along the width direction of the placement notch 12, and correspondingly, the hollow groove 33 also extends along the width direction of the placement notch 12 to form a strip-shaped hollow groove 33, which is disposed between the electrical components of the display area 31 and the electrical components of the main control area 32. In this way, the creepage distance between the electrical components of the display area 31 and the electrical components of the main control area 32 can be increased by using the hollow groove 33, thereby improving electrical safety.

[0072] It should be noted that in this embodiment, the second baffle 5 cannot be directly connected to the first baffle 11. The second baffle 5 needs to be spaced a certain distance from the first baffle 11. At the same time, the second baffle 5 and one side edge of the lower cover 1 need to be spaced a certain distance apart to ensure that the upper part of the second baffle 5 can pass smoothly through the hollow groove 33 on the circuit board 3 and extend to the upper area of ​​the circuit board 3.

[0073] In some embodiments, refer to Figure 6 and Figure 8 As shown, the circuit board 3 can be L-shaped as a whole. The display area 31 of the circuit board 3 extends along the width direction of the induction cooker, that is, the display area 31 of the circuit board 3 extends from the first side edge 14 of the lower cover 1 towards the second side edge 15. The main control area 32 of the circuit board 3 extends perpendicular to the width direction of the induction cooker, so that the main control area 32 and the display area 31 form an angle. The first baffle 11 is set on the side edge of the display area 31 that is relatively close to the main control area 32 to separate the display area 31 from the fan 4 and the heat sink 321. The second baffle 5 is set at a distance from the first baffle 11 and is set between the electrical components of the display area 31 and the main control area 32, so that the first baffle 11 and the second baffle 5 together form a partition structure. The fan 4 and the main control area 32 are located on one side of the first baffle 11 and the second baffle 5, and the display area 31 is located on the other side of the first baffle 11 and the second baffle 5, thereby achieving a good effect of isolating oil fumes.
