Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, and in particular to a panel structure for an induction cooker. Background Technology

[0002] Induction cookers, as efficient and convenient kitchen heating devices, are widely used in homes and commercial spaces. As a key component of the induction cooker, the control panel not only needs to possess basic properties such as high temperature resistance, impact resistance, and ease of cleaning, but its appearance design and ease of operation are also increasingly attracting user attention.

[0003] To improve the user experience and aesthetics of induction cookers, existing technologies have developed solutions for optimizing the cooker panel design. For example, Chinese utility model patent document (publication number CN208418847U) discloses a novel induction cooker panel structure. This structure includes a tightly connected glass panel and a panel shelf. The glass panel has a functional control area, and a light-transmitting strip is provided around the perimeter of the functional control area. The panel shelf has LED strip grooves corresponding to the light-transmitting strips, and LED strip devices are installed within these grooves. These LED strip devices are pressed and fixed between the glass panel and the panel shelf. The LED strip devices in the LED strip grooves emit light, which is then projected outwards through the light-transmitting strip, illuminating the area around the functional control area. This not only makes it easier for users to operate the functional control area in dim environments, reducing operational difficulty, but also enhances the product's aesthetics and improves its market competitiveness.

[0004] However, the panel structure in the aforementioned prior art still has certain drawbacks. The core issue lies in the dedicated LED strip slot on the panel shelf, which limits its compatibility to induction cookers with lighting functionality. For induction cookers without lighting, since no LED strip is needed, the panel shelf with the LED strip slot cannot be directly adapted. This necessitates the development of two separate sets of molds for the panel shelf – one with the LED strip slot for products with lighting, and another without for products without lighting. Since panel shelves typically involve complex structures such as clips and threaded posts, the design and manufacturing of the molds are challenging. The investment in two sets of molds significantly increases production costs, hindering the product's market competitiveness. Therefore, designing a panel structure compatible with both induction cookers with and without lighting, thereby reducing mold investment and production costs, has become a pressing issue in this field. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a panel structure for an induction cooker.

[0006] An induction cooker panel structure designed for this purpose includes a panel, a panel support, a circuit board, and a light-emitting element connected to the circuit board. The panel support has a through-hole extending vertically. A ring-shaped plate is provided directly below the through-hole. The ring-shaped plate has a protruding ring extending upward to the through-hole. A light-emitting space is formed between the protruding ring and the sidewall of the through-hole. The panel is positioned as a light-transmitting area corresponding to the light-emitting space. The light-emitting element is disposed within the light-emitting space or the light from the light-emitting element illuminates the light-emitting space.

[0007] Preferably, the annular plate has a through opening at the top and bottom, through which the light-emitting element extends into the light-emitting space.

[0008] Preferably, the light-emitting space is provided with a light guide.

[0009] Preferably, the lower surface of the light guide is provided with an upwardly extending clearance groove, and the light-emitting element passes through the opening and is inserted into the clearance groove.

[0010] Preferably, the circuit board is fixedly connected to the annular plate.

[0011] Preferably, the annular plate is fixedly connected to the panel support.

[0012] Preferably, the panel and the panel bracket are fixedly connected by adhesive.

[0013] Compared with existing technologies, this invention achieves flexible switching of functions through modular design, further enhancing the versatility of the panel bracket and significantly reducing production costs. When the induction cooker needs lighting, only the annular plate and light-emitting element need to be installed. In this case, the convex ring of the annular plate extends upward to the through-hole of the panel bracket, forming a light-emitting space with the side wall of the through-hole. The light-emitting element is placed in this space or its light shines into this space, thus achieving illumination through the light-transmitting area of ​​the panel. When the induction cooker does not require lighting, the annular plate and light-emitting element can be omitted, and the panel bracket requires no structural modification. This design completely avoids the problem of developing two sets of panel bracket molds due to functional differences, greatly reducing mold investment, lowering production, warehousing, and management costs, and significantly enhancing the product's market competitiveness.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See Figures 1-7 An induction cooker panel structure includes a panel 10, a panel support 20, a circuit board 40, and a light-emitting element 410 connected to the circuit board 40. The panel support 20 is provided with a through-hole 210 extending vertically. An annular plate 30 is provided directly below the through-hole 210. The annular plate 30 is provided with a protruding ring 310 extending upward to the through-hole 210. A light-emitting space 50 is formed between the protruding ring 310 and the side wall of the through-hole 210. The panel 10 is configured as a light-transmitting area 100 corresponding to the position of the light-emitting space 50. The light-emitting element 410 is disposed within the light-emitting space 50 or the light from the light-emitting element 410 is irradiated into the light-emitting space 50.

[0023] The working principle of this induction cooker panel structure is as follows:

[0024] In the overall structure, the panel 10 serves as the upper operating surface of the induction cooker. Its light-transmitting area 100 corresponds to the position of the through-hole 210 of the panel support 20, providing a path for light to pass through. The through-hole 210 on the panel support 20 runs vertically through the panel and is an important structural basis for forming the light-emitting space 50. The annular plate 30 is securely installed directly below the through-hole 210 by existing methods such as ultrasonic welding or screw fixing. Its upward-extending convex ring 310 extends into the through-hole 210, so that the outer wall of the convex ring 310 and the inner wall of the through-hole 210 enclose and form the upper open light-emitting space 50.

[0025] When the induction cooker needs to activate its lighting function, the light-emitting element 410 connected to the circuit board 40 is placed within the light-emitting space 50, or its light can directly illuminate the light-emitting space 50. At this time, the circuit board 40 controls the light-emitting element 410 to emit light, and the light propagates within the light-emitting space 50. Since the upper side of the light-emitting space 50 corresponds to the light-transmitting area 100 of the panel 10, the light can smoothly pass through the light-transmitting area 100 and shine outward, thereby illuminating the corresponding area of ​​the panel 10, making it convenient for users to operate in dimly lit environments.

[0026] When the induction cooker does not require lighting, it is sufficient to omit the ring plate 30 and the light-emitting element 410. In this case, the through-hole 210 of the panel bracket 20 does not need to serve as a light-emitting space, and the entire panel structure can still meet the basic usage requirements of the induction cooker.

[0027] The light-emitting element 410 uses LED beads integrated on the circuit board 40. This design directly integrates the LED beads into the corresponding positions on the circuit board 40, eliminating the need for additional independent mounting structures. This not only saves assembly space but also simplifies circuit connections. LED beads are characterized by low energy consumption, high luminous efficiency, and long lifespan, providing stable lighting. When the induction cooker needs to achieve the lighting function, the circuit board 40 can directly power and control these integrated LED beads, ensuring that the emitted light accurately targets the light-emitting space 50, thereby achieving the lighting effect through the light-transmitting area 100 of the panel 10. When the lighting function is not required, these LED beads can be omitted from the circuit board 40, avoiding unnecessary component waste and further demonstrating the flexibility and economy of the structural design.

[0028] See Figures 1-7 The annular plate 30 has a through-hole 320 through which the light-emitting element 410 extends into the light-emitting space 50. The opening 320 of the annular plate 30 provides a precise channel for the light-emitting element 410, allowing the LED beads integrated on the circuit board 40 to extend directly into the light-emitting space 50. This design ensures that the light source is closer to the light-emitting space, reducing light transmission loss and enhancing the lighting effect, while also making the overall structure more compact and avoiding cluttered component layout.

[0029] See Figure 2 and Figure 5 The light-emitting space 50 is provided with a light guide 60. The light guide 60 in the light-emitting space 50 can guide and homogenize the light emitted by the light-emitting element 410, reduce the light spots caused by direct light, and make the light more evenly pass through the light-transmitting area 100 of the panel 10, thereby improving the softness and consistency of the lighting.

[0030] See Figure 3 and Figure 5 The lower surface of the light guide 60 is provided with an upwardly extending clearance groove 610, and the light-emitting element 410 is inserted into the clearance groove 610 through the opening 320. The clearance groove 610 on the lower surface of the light guide 60 can accommodate the light-emitting element 410 passing through the opening 320, so that the light-emitting element 410 and the light guide 60 are precisely aligned, reducing light loss in the gap between the two, allowing light to enter the light guide 60 more efficiently, and enhancing the light guiding and uniform light effect.

[0031] In this invention, the circuit board 40 is fixedly connected to the annular plate 30.

[0032] In this utility model, the panel 10 and the panel support 20 are fixedly connected by adhesive.
