Description

Technical Field

[0001] This application relates to the field of oven knob accessories, and more particularly to an oven knob base structure with a built-in circuit board. Background Technology

[0002] In the field of kitchen appliances such as ovens, with the continuous development of technology, intelligence and multi-functionality have become important development trends. The design of built-in circuit boards enables ovens to achieve more precise temperature control, diverse cooking modes, and other functions, greatly improving the user experience and cooking results. The application of this technology has also driven the oven industry towards a more high-end and convenient direction, meeting consumers' demands for high-quality kitchen appliances. At the same time, the application of circuit boards has laid the foundation for the automation and intelligence of ovens, promoting technological progress throughout the entire kitchen appliance industry.

[0003] In traditional oven designs, the knob structure mainly consists of a knob housing and a knob base. A circuit board is installed inside the base to control the indicator light on the knob housing and its opening and closing. The installation of the circuit board is usually done in a simple and direct way. One common method is to use screws to fix the circuit board to the base. This is achieved by pre-drilling corresponding screw holes in both the base and the circuit board, and then tightening the screws. This method provides a relatively stable fixation. Another method is to use glue to directly attach the circuit board to a specific location on the base.

[0004] However, traditional circuit board mounting methods have significant drawbacks. Screw mounting requires tools, making the installation process cumbersome, and removing the screws is inconvenient for subsequent maintenance or circuit board replacement. Adhesive bonding, once applied, is difficult to adjust or replace, and the adhesive may fail at high temperatures, affecting the circuit board's stability. Therefore, there is room for improvement. Summary of the Invention

[0005] To facilitate the installation of the circuit board, this application provides a structure for an oven knob base with a built-in circuit board.

[0006] The oven knob base structure with a built-in circuit board provided in this application adopts the following technical solution: An infrared oven button for improving the stability of circuit board installation includes a base and a cover plate. The base has a cavity for placing the circuit board inside, and a first limiting part and a second limiting part are disposed opposite to each other in the cavity. The cover plate is disposed between the first limiting part and the second limiting part, and the circuit board is housed inside the cover plate. The first limiting part has a first slot, and the second limiting part has a second slot. One end of the cover plate has a first hook that engages with the first slot, and the other end of the cover plate has a second hook that engages with the second slot.

[0007] By adopting the above technical solution, a cavity is set in the base for placing the circuit board, and the cover plate is limited by the first limiting part and the second limiting part that are set in opposite directions. The circuit board is housed inside the cover plate. At the same time, the cover plate is fixed in the cavity by the snap-fit ​​cooperation of the first hook and the first slot, and the second hook and the second slot, which facilitates the installation of the circuit board.

[0008] Preferably, there are two first card slots, which are placed on both sides of the first limiting part, and the second card slot is located in the middle of the second limiting part.

[0009] By adopting the above technical solution, the layout of placing the two first slots on both sides of the first limiting part and the second slot in the middle of the second limiting part can make the cover plate more evenly stressed during installation, enhance the stability of the cover plate installation, facilitate the installation of the circuit board, and improve the overall stability of the oven knob base structure.

[0010] Preferably, the end of the first hook is provided with a beveled guide surface, and the top of the first slot is provided with a beveled guide groove. When the cover plate is installed in the cavity, the first hook is engaged in the first slot under the guiding action of the beveled surface and the beveled guide groove.

[0011] By adopting the above technical solution, when installing the cover plate, the oblique guide surface at the end of the first hook cooperates with the oblique guide groove at the top of the first slot, so that the first hook can be smoothly inserted into the first slot, which facilitates the installation of the circuit board and makes the installation process of the cover plate and the base smoother.

[0012] Preferably, the base is provided with a plurality of clearance holes, which are respectively connected to the bottom of the first slot and the second slot.

[0013] By adopting the above technical solution, and utilizing the clearance hole connected to the bottom of the first and second card slots, the hooks are provided with room to move during installation or removal, making the installation and removal of the circuit board more convenient.

[0014] Preferably, both ends of the cover plate are provided with convex arc surfaces, and the first limiting part and the second limiting part are provided with concave arc surfaces that are adapted to the convex arc surfaces on their opposite sides. When the cover plate is installed in the cavity, the convex arc surfaces of the cover plate fit against the concave arc surfaces of the first limiting part and the second limiting part.

[0015] By adopting the above technical solution, the cover plate can fit better with the first limiting part and the second limiting part, thereby improving the stability and tightness of the cover plate installation and further facilitating the installation and fixation of the circuit board.

[0016] Preferably, positioning plates are provided at both ends of the second limiting part, and when the cover plate is installed in the cavity, the two positioning plates are located on both sides of the cover plate.

[0017] By adopting the above technical solutions, the accuracy and stability of the cover plate installation position can be further guaranteed, and the circuit board installation efficiency can be improved.

[0018] Preferably, the cover plate is a transparent cover plate.

[0019] By adopting the above technical solution, the light from the circuit board can shine through the cover plate, making it easy to display the color change of the light on the button casing.

[0020] Preferably, the base has a plurality of plum blossom-shaped holes, which are distributed on both sides of the cover plate.

[0021] By adopting the above technical solution, the screws can be used to fix the base to the oven through the Phillips-shaped holes, making it easy to fix the base.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The first and second limiting parts in the recessed cavity of the base cooperate with the first and second hooks of the cover plate, avoiding the use of screws and glue, making the installation and removal of the circuit board more convenient; 2. The snap-fit ​​between the first and second limiting parts and the cover plate improves the limiting and snap-fit ​​design, ensuring the stability and accuracy of circuit board installation and preventing loosening or displacement; 3. The oblique guide surface of the first hook and the oblique guide groove at the top of the first slot guide each other, making it easier for the cover plate to be inserted into the first slot and making it easier to install the circuit board.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a structure for an oven knob base 1 with a built-in circuit board 2, referring to... Figure 1 and Figure 2 The system includes a base 1 and a cover plate 3. The base 1 is circular and has an internal cavity 7 for placing a circuit board 2. A first limiting part 4 and a second limiting part 5 are disposed opposite each other within the cavity 7. The cover plate 3 is positioned between the first limiting part 4 and the second limiting part 5. The circuit board 2 is housed within the cover plate 3 and covered with a soft material for waterproofing, dustproofing, and insulation. The first limiting part 4 has a first slot 41, and the second limiting part 5 has a second slot 51. One end of the cover plate 3 has a first hook 32, and the other end has a second hook 34. The cover plate 3 is fixed in place by the engaging action of the first hook 32 with the first slot 41 and the second hook 34 with the second slot 51, thus accommodating the circuit board 2 for easy installation and removal, ensuring installation stability and accuracy. This snap-fit ​​structure requires no tools, simplifies installation and removal, and effectively prevents the circuit board 2 from loosening or shifting.

[0029] Referring to 1 and 3, specifically, the cavity 7 is a recessed space formed inside the base 1, characterized by its suitable size and shape to accommodate the circuit board 2 and the cover plate 3. The shape of the cavity 7 is typically adapted to the outline of the circuit board 2 and the cover plate 3, for example, it can be circular. From an alternative perspective, the cavity 7 can also be designed into other polygonal or irregular shapes according to actual needs, as long as it meets the requirements for placing the circuit board 2 and the cover plate 3.

[0030] The first limiting part 4 and the second limiting part 5 are disposed opposite each other within the cavity 7. The first limiting part 4 is used to engage with one end of the cover plate 3, and the second limiting part 5 is used to engage with the other end of the cover plate 3. The first limiting part 4 and the second limiting part 5 are characterized by having a certain height and strength to perform the functions of limiting and locking. They are arc-shaped plate structures that bulge upward from the bottom of the cavity 7, and the opposite sides of the first limiting part 4 and the second limiting part 5 are both concave arc surfaces 6. The material can be the same plastic or metal material as the base 1. Alternatively, they can also be independent components fixed to the inner wall of the cavity 7 by welding or other means.

[0031] The first slot 41 is a structure used to engage with the first hook 32 of the cover plate 3. The first slot 41 is characterized by having a suitable depth and width to accurately accommodate the first hook 32. The shape of the first slot 41 can be rectangular or trapezoidal, etc., and its top position is also provided with an oblique guide groove 42 to facilitate the engagement of the first hook 32. From the perspective of replaceable features, the shape and size of the first slot 41 can be adjusted according to the design of the first hook 32, and the oblique guide groove 42 can also adopt other forms of guide structures, such as an arc-shaped guide surface.

[0032] The second slot 51 is used to engage with the second hook 34 of the cover plate 3. The second slot 51 has similar structural features to the first slot 41, with suitable dimensions and shape to ensure a good fit with the second hook 34. The second slot 51 is located in the middle of the second limiting part 5, which makes the cover plate 3 more stable during installation. Alternatively, the position of the second slot 51 can be adjusted according to the actual design.

[0033] The combination logic of the first limiting part 4 and the second limiting part 5 is to cooperate with each other to limit and engage the cover plate 3. When the cover plate 3 is installed in the cavity 7, the first limiting part 4 and the second limiting part 5 can constrain the position of the cover plate 3, preventing it from swaying left and right or shifting forward and backward. The engagement of the first locking groove 41 and the second locking groove 51 with the first locking hook 32 and the second locking hook 34 of the cover plate 3 further ensures the stability of the cover plate 3 installation.

[0034] In this embodiment, there are two first slots 41, which are placed on both sides of the first limiting part 4. Correspondingly, there are also two first hooks 32, which are placed on both sides of the cover plate 3. This arrangement increases the number of engagement points between the cover plate 3 and the first limiting part 4, further improving the stability of the cover plate 3 installation. The two first slots 41 have the same structural features, both consisting of a straight rod and a hook. The straight rod extends towards the corresponding first slot 41, and the hook is located at the end of the straight rod and is used to engage with the first slot 41.

[0035] The first hook 32 is located on both sides of the end of the cover plate 3, and the end of the first hook 32 is provided with a beveled guide surface 33. The first hook 32 is characterized by having a certain degree of elasticity and strength so that it can be smoothly engaged into the first slot 41. The function of the beveled guide surface 33 is to cooperate with the beveled guide groove 42 at the top of the first slot 41 during installation, guiding the first hook 32 to accurately engage into the first slot 41. The first hook 32 can be hook-shaped, and the material can be plastic or metal with a certain degree of elasticity. Alternatively, the first hook 32 can also adopt other shapes of engagement structures, as long as it can achieve the engagement function with the first slot 41.

[0036] The second hook 34 is located in the middle of the other end of the cover plate 3. Its construction features are somewhat different from those of the first hook 32. The second hook 34 eliminates the straight rod part and only retains the hook part, which is used to engage with the second slot 51 to ensure the stability of the engagement.

[0037] Both ends of the cover plate 3 are provided with outwardly convex arc surfaces 31, which are characterized by outwardly protruding arc-shaped surfaces. The outwardly convex arc surfaces 31 are adapted to the concave arc surfaces 6 on the opposite side of the first limiting part 4 and the second limiting part 5. When the cover plate 3 is installed in place, the outwardly convex arc surfaces 31 of the cover plate 3 fit against the concave arc surfaces 6 of the limiting parts. This can further enhance the stability and accuracy of the installation of the cover plate 3. The radius and curvature of the outwardly convex arc surfaces 31 can be adjusted according to the design of the concave arc surfaces 6.

[0038] The combination logic of the first hook 32, the second hook 34, and the outwardly convex arc surface 31 of the cover plate 3 is to jointly achieve a stable connection between the cover plate 3 and the base 1. The first hook 32 and the second hook 34, through their engagement with the first slot 41 and the second slot 51, fix the cover plate 3 in the cavity 7 of the base 1. The fit between the outwardly convex arc surface 31 and the inwardly concave arc surface 6 further improves the stability and accuracy of the installation, enabling the cover plate 3 and the circuit board 2 to be firmly installed in the base 1.

[0039] In addition, the base 1 is provided with several clearance holes 11, which are respectively connected to the lower part of the first slot 41 and the second slot 51. The function of the clearance holes 11 is to facilitate the operation of the hooks through the clearance holes 11 when removing the cover plate 3, so that the hooks are separated from the slots, thereby realizing the removal of the cover plate 3. The clearance holes 11 can be circular or rectangular, etc., and their size should be large enough to allow the tools to pass through. Alternatively, the number and position of the clearance holes 11 can be adjusted according to actual needs.

[0040] The base 1 also has several perforated holes 12, which are located on both sides of the cover plate 3. Screws can be used to fix the base 1 to the oven through the perforated holes 12, making it easy to secure the base 1. Alternatively, the perforated holes 12 can be other shapes, such as round holes or square holes.

[0041] In this embodiment, the cover plate 3 is a transparent cover plate 3 so that the light from the circuit board 2 can pass through the cover plate 3, thereby achieving the purpose of displaying the color change of the light at the button housing.

[0042] The implementation principle of this embodiment is as follows: The oven knob base 1 structure with built-in circuit board 2 in this embodiment uses a unique snap-fit ​​structure design to avoid the cumbersome operation of traditional screw fixing methods, the non-adjustability of glue bonding methods, and the instability of simple snap-fit ​​structures. By utilizing the snap-fit ​​cooperation between the first hook 32 and the first slot 41, and the second hook 34 and the second slot 51, convenient installation and disassembly of the circuit board 2 and the cover plate 3 are achieved. The installation process requires no tools and is simple to operate. At the same time, the fit between the convex arc surface 31 and the concave arc surface 6, as well as the design of the avoidance hole 11 and the plum blossom hole 12, further improve the stability, accuracy, and practicality of the installation, providing a more reliable and convenient solution for the installation of circuit board 2 in the oven, and effectively improving and enhancing the existing oven circuit board 2 installation method.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
