Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an installation structure for an electronic control component and a range hood. Background Technology

[0002] In existing technologies, electrical control components (such as electrical control boxes) are typically inserted horizontally into mating holes within the electrical control cavity via screws or other connectors. However, due to the small size and compact structure of the electrical control cavity, and the limited installation / maintenance opening at the top, operators need to apply rotational torque horizontally when assembling or performing subsequent maintenance using tools such as wrenches and screwdrivers. The top opening usually only allows tools to enter the cavity vertically or nearly vertically. Forcing horizontal operation may cause the tool handle to interfere with the cavity wall, adjacent components, or the electrical control box. Even if the tool head covers the screw head, the lack of sufficient oscillation angle makes it difficult for the operator to apply continuous torque, especially in narrow, deep cavities where tightening or disassembly is almost impossible, resulting in low assembly efficiency and poor maintainability.

[0003] Therefore, there is an urgent need for a structural design that improves the assemblability and maintainability of electronic control components within a confined space. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an installation structure for an electronic control component, which allows the installation tool to smoothly reach the head of the connector along the inclined direction, and obtains sufficient operating space and lever arm length, significantly improving the assembly reliability and on-site maintainability of the electronic control component.

In this way, the axial direction of the connector is basically consistent with the path of the operating tool extending from the top opening, allowing the installation tool to smoothly reach the head of the connector along the tilted channel, and obtaining sufficient operating space and lever arm length. This structure significantly improves the assembly reliability and on-site maintainability of the electrical control components without increasing the overall volume of the electrical control cavity, avoiding fastening failures or maintenance difficulties caused by spatial interference.

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-7 Description of a range hood 100 according to an embodiment of the present utility model.

[0022] like Figures 1-7 As shown, the installation structure of the electronic control component includes: the main body of the range hood and the electronic control component.

[0023] The main body of the range hood has an electrical control cavity 1, and a connection position 11 is provided inside the electrical control cavity 1. The electrical control component is located inside the electrical control cavity 1. The electrical control component includes an electrical control box 2. The electrical control box 2 is used to house the electrical control board. The electrical control box 2 has a connection part 21. The connection part 21 is fixedly connected to the connection position 11 through a connector, thereby fixing the electrical control component inside the electrical control cavity 1.

[0024] It is understandable that electrical control components (such as the electrical control box 2) are typically installed horizontally in the connection position 11 of the electrical control cavity 1 via screws or other connectors. However, the electrical control cavity 1 is small and compact, with a limited-sized installation / maintenance port 4 at the top. When assembling or performing subsequent maintenance, operators need to apply rotational torque along the screw axis (horizontal direction) using tools such as wrenches and screwdrivers, but the top opening usually only allows the tool to enter the cavity vertically or nearly vertically. If horizontal operation is forced, the tool handle may interfere with the cavity wall, adjacent components, or the electrical control box 2. Even if the tool head covers the screw head, due to the lack of sufficient swing angle, it is difficult for the operator to apply continuous torque, especially in the narrow and deep cavity where tightening or disassembly is almost impossible. Auxiliary tools are often required, or other components need to be disassembled to make room, resulting in poor assembly efficiency and maintainability.

[0025] Therefore, the present invention optimizes the design of the connecting part 21 of the electrical control box 2, that is, at least the surface of the connecting part 21 away from the connecting position 11 is inclined, the connecting position 11 is provided with a first connecting hole 12, the connecting part 21 is provided with a second connecting hole 22 corresponding to the first connecting hole 12, and the connector passes through the second connecting hole 22 and the first connecting hole 12 to connect the connecting part 21 to the connecting position 11.

[0026] Specifically, the surface of the connecting part 21 away from the connecting position 11 is inclined, so that the second connecting hole 22 is located on the inclined surface. When the user needs to connect the connecting part 21 to the connecting position 11, the installation tool is tilted to insert the screw into the second connecting hole 22 and connect the connecting part 21 to the connecting position 11 with the screw.

[0027] This can also be understood as the connecting part 21 being closer to the side of the installation tool's operating surface, such that the axis of the second connecting hole 22 opened on the inclined surface is perpendicular to the inclined surface. Correspondingly, the first connecting hole 12 on the connecting position 11 inside the electrical control cavity 1 is also set at the same inclination angle to ensure that the two holes are coaxially aligned. Thus, the connector (such as a screw) passes through the second connecting hole 22 and the first connecting hole 12 along the inclined axis, with its operating end facing the installation / maintenance port 4 at the top of the electrical control cavity 1. It should be noted that the orientation of the inclined surface matches the maintenance port 4 of the electrical control cavity 1, allowing the operating tool to smoothly extend along the inclined path and directly act on the head of the connector.

[0028] In this way, when the operator inserts the installation tool through the top opening, the tool can enter obliquely along a direction consistent with or close to the axis of the connector, directly acting on the screw head. This eliminates the need for the operating end of the tool to be perpendicular to the connector 21, significantly improving accessibility and reliability. Compared to existing technologies, this avoids operational interference caused by the tool path being orthogonal to the screw axis in traditional horizontal connection structures 3. This design significantly improves the ease of assembly and on-site maintainability of the electrical control components without increasing the volume of the electrical control cavity 1.

[0029] Therefore, in existing electrical control boxes 2, the connector is horizontally inserted into the connection position 11 within the electrical control cavity 1, making it difficult to apply effective torque horizontally after the tool is inserted from the top of the cavity. This results in assembly difficulties, unreliable fastening, and subsequent maintenance difficulties. This invention addresses this by providing an inclined mounting surface on the side of the electrical control box 2 connection portion 21 away from the connection position 11 of the electrical control cavity 1. This mounting surface is inclined towards the installation / maintenance port 4 at the top of the electrical control cavity 1. A second connection hole 22 perpendicular to this mounting surface is formed. The connector passes through the second connection hole 22 and the first connection hole 12 in sequence, thereby fixing the connector to the connection position 11 in an inclined direction, with the operating end of the connector facing the top opening. In this way, the axial direction of the connector is basically consistent with the path of the operating tool inserted from the top opening, allowing the installation tool to smoothly reach the head of the connector along the inclined channel and obtain sufficient operating space and lever arm length. This structure significantly improves the assembly reliability and on-site maintainability of the electrical control components without increasing the overall volume of the electrical control cavity 1, avoiding fastening failures or maintenance difficulties caused by spatial interference.

[0030] In some embodiments of this utility model, such as Figure 4 and Figure 5As shown, the surface of the connecting part 21 away from the connecting position 11 is inclined backward from top to bottom.

[0031] Specifically, the surface of the connecting part 21 away from the connecting position 11 is inclined from top to bottom and backward. "Top" refers to the direction near the top of the electrical control cavity 1 in the normal installation state, "bottom" refers to the direction near the bottom of the electrical control cavity 1, and "backward" refers to the side away from the user and near the wall. Due to the existence of this inclined surface, the axis of the second connecting hole 22 is perpendicular to this inclined surface, thus extending upward from front to back and coaxially aligned with the first connecting hole 12 on the connecting position 11. Accordingly, the connector passes through the second connecting hole 22 and the first connecting hole 12 sequentially along this inclined axis, with its head facing obliquely upward, directly opposite the installation / maintenance port 4 at the top of the electrical control cavity 1. This arrangement allows the operator to smoothly insert the installation tool into the electrical control cavity 1 from the top opening along an oblique path from back to top to front to bottom, directly acting on the head of the connector, thereby achieving reliable fastening or convenient disassembly.

[0032] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the connecting part 21 is inclined, and the direction of inclination of the connecting part 21 toward the surface away from the connecting position 11 is the same. The connecting position 11 has a connecting surface 13 that matches the inclination of the connecting part 21.

[0033] It is understandable that if the connection interface between the connecting position 11 and the connecting part 21 is not inclined, but rather vertical, although the connecting surface 13 of the connecting position 11 and the surface of the connecting part 21 facing the connecting position 11 can fit together, the first connecting hole 12 of the connecting position 11 is not perpendicular to the connecting surface 13 of the connecting position 11. Thus, when the connector is pre-tightened, the direction of the clamping force (along the hole axis) is inconsistent with the normal direction of the mating surface, generating an additional bending moment. This causes the connector to bear bending stress, and under vibration, the connector is prone to fatigue cracks or even breakage. Furthermore, machining a non-perpendicular inclined hole on a vertical surface is complex, and the hole position accuracy is difficult to guarantee, affecting assembly.

[0034] Therefore, this utility model improves the connecting part 21 and the connecting position 11. The connecting part 21 of the electrical control box 2 includes two main surfaces: an inner surface facing the connecting position 11 and an exposed surface away from the connecting position 11. Both surfaces have the same inclination direction, that is, both the inner surface and the exposed surface are inclined from top to bottom and backward. Correspondingly, the connecting position 11 in the electrical control cavity 1 is also provided with a corresponding inclined connecting surface 13. The inclination of the connecting surface 13 is perfectly matched with the inclination of the connecting part 21, that is, the inclination angles of the two are the same and the directions are consistent.

[0035] In this way, the electrical control box 2 is face-to-face with the connection position 11 through its connecting part 21, and the connecting parts are naturally arranged in the inclined direction. While maintaining good tool accessibility, the preload can be applied vertically to the connecting part 21 and the connection position 11, so as to achieve uniform load transfer, structural stability and reliability, and at the same time greatly simplify the mold and processing technology.

[0036] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 7 As shown, a connection structure 3 is provided inside the electronic control cavity 1. The connection structure 3 includes a main board 31 and a connecting plate 32. The main board 31 is connected to the front wall of the electronic control cavity 1, and the connecting plate 32 is disposed on the side of the main board 31 facing the electronic control assembly. The surface of the connecting plate 32 that connects with the connecting part 21 forms a connection position 11.

[0037] It is understood that the electrical control cavity 1 is provided with an independent connection structure 3, which is used to provide a connection position 11 for cooperating with the electrical control components, thereby avoiding the direct processing of complex installation features on the main wall of the electrical control cavity 1.

[0038] Specifically, the connecting structure 3 includes a main board 31 and a connecting plate 32. The main board 31 is fixedly connected to the front wall of the electronic control cavity 1, anchoring the entire connecting structure 3 to the main body. The "front wall" refers to the cavity wall on the side of the main body of the range hood facing the user's operating surface. The main board 31 can be reliably connected to the front wall of the electronic control cavity 1 using screws, clips, welding, or other methods to ensure overall structural stability. The connecting plate 32 is located on the side of the main board 31 facing the electronic control components (i.e., extending into the electronic control cavity 1) and is fixedly connected to the main board 31. Preferably, the main board 31 and the connecting plate 32 are integrally formed to improve rigidity and assembly accuracy.

[0039] The surface of the connecting plate 32 facing the electrical control box 2 forms a connection position 11. This connection position 11 has a first connection hole 12, which aligns with a second connection hole 22 on the connecting portion 21 of the electrical control box 2. A connector (such as a screw) passes through the second connection hole 22 and the first connection hole 12 in sequence to fix the electrical control box 2 onto the connecting plate 32. Thus, when the electrical control box 2 is installed in place, the connecting portion 21 and the connecting plate 32 achieve surface-to-surface contact. The connector is inserted perpendicular to this inclined surface, which facilitates the oblique insertion of tools from the maintenance port 4 at the top of the electrical control cavity 1 and ensures that the preload is evenly applied across the entire contact surface, improving connection reliability.

[0040] Therefore, by decoupling the connection function of the connection position 11 from the main structure of the electrical control cavity 1, this utility model avoids machining installation features on the front wall of the electrical control cavity 1, ensuring the structural stability of the front wall. Furthermore, the connection plate 32 can be flexibly adjusted in terms of tilt angle and hole layout for different specifications of electrical control boxes 2, or different connection plates 32 or connection structures 3 can be directly replaced to adapt to different specifications of electrical control boxes 2, avoiding changes to the main structure of the electrical control cavity 1 and improving compatibility. If the connection structure 3 is worn or damaged, only the connection structure 3 needs to be replaced, without replacing the entire main body, reducing maintenance costs.

[0041] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 7 As shown, the connecting plate 32 includes: a first plate 33 and a second plate 34. The first plate 33 connects the second plate 34 and the main plate 31, and the second plate 34 forms a connection position 11.

[0042] Specifically, one end of the first board 33 is connected to the main board 31, and the other end is connected to the second board 34, serving as a support and transition. For example... Figure 7 As shown, the first plate 33 can extend in the front-to-back direction, or it can be bent, stepped, or inclined according to the internal spatial layout of the electrical control cavity 1 to avoid other functional components. The second plate 34 is located at the end of the first plate 33 away from the main board 31, and its surface facing the electrical control box 2 forms a connection position 11. The second plate 34 has a first connection hole 12 for alignment and mating with the second connection hole 22 on the connection part 21 of the electrical control box 2. A connector (such as a screw) passes through the two holes to fix the electrical control box 2 to the second plate 34.

[0043] Through the above design, the second plate 34 is responsible for bearing the connection load, while the first plate 33 undertakes the transmission and support functions, and is not limited by the installation height of the main board 31 or the front wall structure. By adjusting the size and spatial position of the second plate 34, the second plate 34 can be precisely arranged in the installation position within the electrical control cavity 1 to adapt to the electrical control box 2, thereby improving compatibility.

[0044] In some embodiments of this utility model, such as Figure 4 , Figure 5 and Figure 7 As shown, the second plate 34 is inclined backward from top to bottom, and the connecting part 21 is inclined backward from top to bottom. The inclination of the second plate 34 is at least matched with the inclination of the surface of the connecting part 21 facing one side.

[0045] It is understood that the second plate 34 slopes backward from its upper end to its lower end, forming an inclined plate surface. Correspondingly, the connecting part 21 of the electrical control box 2 is also designed to slope backward from top to bottom, and its side surface facing the second plate 34 (i.e., the mounting surface) has an inclined tendency that matches the second plate 34. Furthermore, the inclination angle (i.e., slope) of the second plate 34 is at least adapted to the inclination angle of the mounting surface of the connecting part 21 facing it. In this way, when the electrical control box 2 is installed in place, the connecting part 21 and the second plate 34 can achieve complete surface-to-surface contact. In this mating state, the second connecting hole 22 opened on the connecting part 21 is coaxially aligned with the first connecting hole 12 opened on the second plate 34 and is inclined. Connecting parts (such as screws) are inserted along the inclined direction, which facilitates the oblique insertion of operating tools from this opening to apply torque. This structure retains good tool accessibility while also ensuring uniform distribution of preload through surface-to-surface bonding, avoiding stress concentration and significantly improving the mechanical strength, vibration resistance, and long-term reliability of the connection.

[0046] Furthermore, combined Figure 6 As shown, the electrical control box 2 has mounting flanges 24 at both ends. The mounting flanges 24 have the same tilt angle as the second plate 34. The mounting flanges 24 have second connecting holes 22. The mounting flanges 24 and the second plate 34 are connected to each other.

[0047] Combination Figure 6 In the embodiment shown, mounting flanges 24 are provided at both ends of the electrical control box 2 (i.e., the two sides along its length direction). The mounting flanges 24 are formed by extending outward from the box body of the electrical control box 2, and are preferably integrally formed with the body of the electrical control box 2.

[0048] The outer surface of the mounting flange 24 is constructed as a plane that slopes backward from top to bottom, with its slope angle being the same as or matching that of the second plate 34. A second connecting hole 22 is formed on the mounting flange 24, the axis of which is perpendicular to the sloped surface of the mounting flange 24. Correspondingly, a first connecting hole 12 is provided on the second plate 34, the axis of which is also perpendicular to the sloped surface of the second plate 34.

[0049] When the electrical control box 2 is installed into the electrical control cavity 1, the mounting flanges 24 on both sides abut against the corresponding second plate 34, forming a surface-to-surface contact interface. Connectors (such as screws) pass through the second connecting hole 22 and the first connecting hole 12 in sequence, fastening the mounting flanges 24 to the second plate 34. Because the mounting flanges 24 and the second plate 34 have the same inclination angle, they achieve a tight fit across the entire area under preload, which not only improves connection rigidity but also effectively disperses mechanical loads and avoids localized stress concentration. Simultaneously, this provides good constraint for the electrical control box 2 in the front-to-back, up-and-down, and torsional directions, significantly improving its installation stability under vibration.

[0050] In some embodiments of this utility model, such as Figure 6 As shown, the electrical control box 2 includes: a first box body 25 and a second box body 26, with a space for accommodating the electrical control board formed between the first box body 25 and the second box body 26. The first box body 25 is provided with first mounting flanges 251 at both ends, with the first mounting flanges 251 located on the side of the first box body 25 facing the second box body 26. The second box body 26 is provided with second mounting flanges 261 at both ends, with the second mounting flanges 261 located on the side of the second box body 26 facing the first box body 25. The first mounting flanges 251 and the second mounting flanges 261 are connected to form a connecting part 21.

[0051] Specifically, when the first box 25 and the second box 26 are assembled together, the first mounting flange 251 and the second mounting flange 261 are joined together at both ends of the electrical control box 2 and fit together to form the connecting part 21. Connecting parts (such as screws) are sequentially passed through the first mounting flange 251, the second mounting flange 261 and the first connecting hole 12 to firmly fix the electrical control box 2 to the second plate 34.

[0052] In this way, the first mounting flange 251 and the second mounting flange 261 form a composite cross section that overlaps or butts in the connection area, effectively increasing the stiffness of the connection part 21. When the connector (such as a screw) passes through the second connection hole 22 on the two flanges and is tightened, the preload acts on both flanges simultaneously, so that the load is borne by the double-layer structure, and it can more effectively resist bending deformation and shear slippage, significantly improving the vibration resistance and structural reliability for long-term use. Moreover, when the operator is maintaining the equipment, the maintenance personnel first remove the maintenance cover plate 5, then loosen the screws between the connection part 21 and the second plate 34, and remove the entire electrical control box 2 from the electrical control cavity 1. The first box 25 and the second box 26 can be manually separated without tools, directly exposing the internal electrical control board for easy inspection.

[0053] In some embodiments of this utility model, such as Figures 2-5 As shown, the main body of the range hood is provided with a maintenance port 4 that communicates with the electrical control chamber 1. The mounting structure of the electrical control components also includes a maintenance cover plate 5, which is detachably installed at the maintenance port 4.

[0054] In this embodiment of the invention, the main body of the range hood has a maintenance port 4 at its top, communicating with the electrical control cavity 1. This maintenance port 4 facilitates the installation, maintenance, or replacement of the electrical control components from the outside. A maintenance cover 5 is detachably installed at the maintenance port 4 to seal the electrical control cavity 1, preventing dust, fumes, or other foreign objects from entering, and also serves an aesthetic purpose. When maintenance of the electrical control components is required, the operator only needs to loosen the screws securing the maintenance cover 5 or release the clips to easily remove the cover 5, exposing the maintenance port 4. At this time, installation tools can be inserted obliquely into the electrical control cavity 1 through the maintenance port 4 to tighten or loosen the connectors of the electrical control box 2. After maintenance, the maintenance cover 5 is reinstalled and the connectors are tightened, restoring the range hood 100 to normal operation. This design not only improves the ease of assembly and maintenance of the electrical control components but also effectively protects the internal electrical components from external environmental influences, extending their service life.

[0055] In some embodiments of this utility model, the projection of the maintenance port 4 onto the electrical control cavity 1 covers the connecting portion 21.

[0056] It is understood that the location of the service port 4 on the main body of the range hood is optimized so that its projected area into the electrical control cavity 1 covers the connecting part 21. Here, "projection" refers to the coverage area formed by projecting into the electrical control cavity 1 along a direction perpendicular to the plane where the service port 4 is located (usually vertically downwards). Since the connecting part 21 has a second connecting hole 22 for installing a connector, and the operating end of the connector (such as a screw head) is located on the side of the connecting part 21 facing the service port 4, when the service cover 5 is removed, the operator can directly insert the installation tool through the service port 4 and apply it to the connector without obstruction, without needing to adjust the tool angle or disassemble other components. This ensures the shortest maintenance path and maximizes the operating space, significantly improving the assembly efficiency of the electrical control components and the convenience of subsequent maintenance.

[0057] According to the second aspect embodiment of the present invention, the range hood 100 adopts the above-described installation structure of the electronic control components.
