Description

Technical Field

[0001] This utility model relates to a constant humidity machine, and more particularly to a waterproof structure for the electrical box of the constant humidity machine. Background Technology

[0002] In modern production and living environments, humidity control machines are widely used to control air humidity to meet the needs of various industries, such as electronics manufacturing, food processing, and scientific research experiments.

[0003] An electrical box is installed inside the humidifier to house electrical components. It is usually installed at the bottom of the drip tray. During the use of the humidifier, when condensate drips or water splashes accidentally, it can damage the electrical components, affect the normal operation of the humidifier, and even cause short circuits and safety accidents. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a waterproof structure for a constant humidity machine electrical box that is compact, easy to process, low in manufacturing cost, and has good waterproof effect.

[0005] This utility model provides a waterproof structure for the electrical box of a constant humidity machine, including a box body with an open front end and a box cover 5 installed at the open front end of the box body. The two sides of the box body extend downward to form support portions 124. The lower end of the support portion 124 is bent outward to form a support mounting portion 125. The edge of the open front end of the box body extends inward to form a constricted portion. The edge of the constricted portion is bent forward to form a connecting portion. The edge of the connecting portion is bent outward to form a mounting portion. There is a gap between the mounting portion and the constricted portion to form a flow guiding area. The box cover 5 is fixed to the mounting portion by bolts. The edge of the box cover 5 is bent backward to form a shielding portion 52. The shielding portion 52 extends backward into the flow guiding area.

[0006] This application features a recessed flow guide area at the open front end of the housing, and a shielding part 52 along the edge of the housing cover. When water flows into the flow guide area from the outside, the water flows along the flow guide area to both sides and cannot enter the connection between the housing and the housing cover. Therefore, it can effectively prevent water from directly entering the housing and achieve waterproofing. Its structural design is reasonable and easy to install, significantly improving the safety and service life of the humidifier and ensuring the stable operation of electrical components.

[0007] Furthermore, the connecting part includes side connecting parts 122 located on both sides of the box body and upper connecting parts 23 located at the upper end of the box body. The two ends of the upper connecting parts 23 are bent downward to form water-blocking parts I231 that can fit against the outer wall of the side connecting parts 122. Through the above structure, on the one hand, the processing difficulty and manufacturing cost are reduced, and on the other hand, the gap between the upper connecting parts can be eliminated to prevent water from seeping in from the gap, further improving the waterproof and seepage-proof effect and ensuring electrical safety.

[0008] Furthermore, the box body includes a box body 1, an upper cover 2 disposed on the upper end of the box body 1, and a lower cover 3 disposed on the lower end of the box body 1. The two sides and rear end edges of the upper cover 2 are bent downward to form a water-blocking part II 22b that can fit against the outer wall of the box body 1. The front end edge of the upper cover 2 is bent downward to form an upper constriction part. The box body adopts a splicing structure, which reduces the processing difficulty and manufacturing cost, and is easy to assemble, which is conducive to improving the overall manufacturing precision. During assembly, spot welding is sufficient, and the welding cost is low.

[0009] Furthermore, the side wall of the enclosure is provided with conduit holes 101 for installing wiring conduits. There are multiple conduit holes 101, which are arranged vertically to facilitate wiring and internal wiring layout.

[0010] Furthermore, the bottom of the box is provided with a spare hole 102. During manufacturing, an annular groove is formed by stamping the bottom of the box. When the spare hole is needed, the material in the groove is gently knocked off to form the spare hole, providing a flexible expansion function and enhancing the practicality and adaptability of the box.

[0011] Furthermore, the enclosure is provided with a mounting plate 4 for installing electrical components. The mounting plate 4 is located on the rear end face of the enclosure 1, and there is a gap between the mounting plate 4 and the rear end of the enclosure 1 to provide installation space for bolts and facilitate the installation of electrical components.

[0012] Furthermore, the edge of the cover 5 is flush with the edge of the box body, which improves the overall aesthetics and ensures that the opening of the box body is maximized, facilitating the installation and maintenance of internal components.

[0013] Furthermore, the edge of the constricted portion is bent forward at 90 degrees to form a connecting portion, and the edge of the connecting portion is bent outward at 90 degrees to form a mounting portion; it is easy to form and facilitates subsequent welding and fixing, and can form a stable support structure, enhance the connection strength between the cover and the body, prevent deformation or loosening caused by external forces, further ensure the safety and stability of internal components, and improve the durability of the overall structure.

[0014] Furthermore, the main body 1 of the enclosure includes a vertically arranged back plate 11. The upper and lower ends of the back plate 11 are bent forward to form a support portion 13. The two sides of the back plate 11 are bent forward to form a side plate 12. The front end of the side plate 12 extends inward to form a side constriction portion 121. The end of the side constriction portion 121 is bent forward to form a side connection portion 122. The end of the side connection portion 122 is bent outward to form a side mounting portion 123. This design facilitates processing, significantly reduces manufacturing costs, and is easy for overall assembly.

[0015] Furthermore, the main body 1, the upper cover 2, and the lower cover 3 are formed by bending metal plates.

[0016] This utility model relates to an electrical box for a humidifier. A recessed flow-guiding area is provided at the open front end of the box, and a shielding part is provided along the edge of the lid. When water flows into the flow-guiding area from the outside, the water flows to both sides along the flow-guiding area, preventing it from entering the connection between the box and the lid. Therefore, it effectively prevents water from directly entering the box, achieving waterproofing. Even with a large flow of water, the water cannot penetrate the box, resulting in excellent waterproofing. The box adopts a split structure, reducing processing difficulty and manufacturing costs, and facilitating assembly with high precision. This utility model's electrical box for a humidifier has a compact structure, reasonable design, low manufacturing cost, and excellent waterproofing, significantly improving the safety and service life of the humidifier and ensuring stable operation of electrical components.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] See Figures 1-13 This utility model provides a waterproof structure for the electrical box of a humidifier, which is installed inside the humidifier to install electrical components and provide waterproof protection, including a box body and a box cover 5.

[0032] The enclosure has a rectangular structure with an open front end. The cover 5 is bolted to the open front end of the enclosure, forming a mounting cavity between the enclosure and the cover for installing electrical components. Specifically, a mounting plate 4 is provided inside the enclosure for installing electrical components. The mounting plate 4 is fixed to the rear end face of the enclosure 1, and there is a gap between the mounting plate 4 and the rear end of the enclosure 1 to provide installation space for bolts during electrical installation, facilitating the installation of electrical components. At the same time, there are multiple conduit holes 101 on the side wall of the enclosure for installing wiring conduits. The conduit holes 101 are arranged vertically for easy wiring and to facilitate the internal wiring layout. One or more spare holes 102 are provided at the bottom of the enclosure. During manufacturing, an annular groove is formed by stamping the bottom of the enclosure. When a spare hole is needed, the material in the groove is gently knocked off to form a spare hole, which provides flexible expansion function and enhances the practicality and adaptability of the enclosure.

[0033] In this application, the edges of the cover 5 (top, bottom, left, and right) are flush with the edges of the box body (top, bottom, left, and right). This not only improves the overall aesthetics but also ensures that the opening of the box body is maximized, facilitating the installation and maintenance of internal components.

[0034] The two sides of the housing extend downward to form support parts 124. The lower end of the support parts 124 is bent outward at 90 degrees to form support mounting parts 125. The support mounting parts 125 are provided with mounting holes for fixing the whole unit into the humidifier. This design makes the bottom surface of the housing higher than the mounting surface, effectively preventing ground water from entering and improving safety and reliability.

[0035] The four edges (top, bottom, left, and right) of the open end of the box extend inward to form a constricted section. This inward extension points towards the center of the open end of the box. The open end has constricted sections on all four sides. For ease of description, the upper one is called the upper constricted section, the lower one the lower constricted section, and the left and right ones the side constricted sections. Each constricted section is a strip-shaped, sheet-like structure. The four inner edges of the constricted sections bend forward to form a connecting section. The edges of the connecting section bend outward to form a mounting section. This outward bending is opposite to the center of the open end. The plane of the mounting section is parallel to the front face of the box. There is a gap between the mounting section and the constricted section, forming a flow guide area. The box cover 5 is a rectangular structure, fixed to the mounting section with bolts. The four edges of the box cover 5 bend backward to form a shielding section 52. The shielding section 52 extends backward into the flow guide area between the mounting section and the constricted section.

[0036] In this embodiment, the edge of the connecting part is bent outward at a 90-degree angle to form a mounting part; it is easy to form and facilitates subsequent welding and fixing, and can form a stable support structure, enhancing the connection strength between the cover and the box body, preventing deformation or loosening caused by external forces, further ensuring the safety and stability of internal components, and improving the durability of the overall structure.

[0037] This application features a recessed flow guide area at the open front end of the housing, and a shielding part 52 along the edge of the housing cover. When water flows into the flow guide area from the outside, the water flows along the flow guide area to both sides and cannot enter the connection between the housing and the housing cover. Therefore, it effectively prevents water from directly entering the housing, achieving waterproofing. Even under a large flow of water, it cannot penetrate into the housing, resulting in excellent waterproofing. Its structural design is reasonable, and installation is simple, significantly improving the safety and service life of the humidifier and ensuring the stable operation of electrical components.

[0038] The connecting parts include side connecting parts 122 located on both sides of the box body and upper connecting parts 23 located at the upper end of the box body. Furthermore, a lower connecting part is provided at the lower end of the box body. The two ends of the upper connecting parts 23 are bent downward to form water-blocking parts I231, which can fit against the outer wall of the side connecting parts 122. Through the above structure, on the one hand, the processing difficulty and manufacturing cost are reduced, and on the other hand, the gap between the upper connecting parts can be eliminated to prevent water from seeping in from the gap, further improving the waterproof and seepage-proof effect and ensuring electrical safety.

[0039] In this application, the box includes a box body 1, an upper cover 2 and a lower cover 3. The upper cover 2 is located at the upper end of the box body 1, and the lower cover 3 is located at the lower end of the box body 1. They are fixedly connected by spot welding to form a box with an open front end.

[0040] See Figure 13 The two sides and rear edge of the upper cover 2 are bent downward at 90 degrees to form a water-blocking part II 22b. The water-blocking part II 22b can fit against the outer wall of the two sides and rear end of the main body 1. The front edge of the upper cover 2 is bent downward at 90 degrees to form an upper constriction part 22a. The end of the upper constriction part 22a is bent forward at 90 degrees to form an upper connecting part 23. The two sides of the upper connecting part 23 are bent downward at 90 degrees to form a water-blocking part I 231. The end of the upper connecting part 23 is bent upward at 90 degrees to form an upper mounting part 24.

[0041] See Figures 11-12 The main body 1 of the box includes a vertically arranged back plate 11, which is rectangular in shape. The top and bottom ends of the back plate 11 are bent forward at 90 degrees to form a support portion 13. The two sides of the back plate 11 are bent forward at 90 degrees to form two side plates 12. The front end of the side plate 12 extends radially inward (towards the center of the open end of the box) to form a side constriction portion 121. The end of the side constriction portion 121 is bent forward at 90 degrees to form a side connecting portion 122. The end of the side connecting portion 122 is bent outward at 90 degrees. A side mounting portion 123 is formed; wherein the top of the side plate 12 and the top of the upper support portion 13 are flush, for mounting the upper cover 2; the lower end of the side plate extends downward to form a support portion 124, and the lower end of the support portion 124 is bent outward at 90 degrees to form a support mounting portion 125, on which a mounting hole is provided; the lower support portion 13 is used to support the lower cover 3, to position the lower cover 3 during assembly, to ensure assembly accuracy, and to serve as a connection end for spot welding.

[0042] The lower cover 3 is rectangular in shape. Its two sides and rear edge are bent at 90 degrees to form a connecting part, which can fit the two sides and rear sidewalls of the box. The front edge of the lower cover 3 is bent upward at 90 degrees to form a lower constriction. The end of the lower constriction is bent forward at 90 degrees to form a lower connecting part. The lower connecting part is not bent downward at 90 degrees to form a lower mounting part.

[0043] The aforementioned upper narrowing, lower narrowing, and side narrowing constitute the narrowing section; the upper connecting section, side connecting section, and lower connecting section together form the connecting structure; the upper mounting section 24, side mounting section 123, and lower mounting section are located on the same plane, forming a rectangular mounting section for mounting the cover 5. This design not only enhances the overall structural stability of the enclosure but also significantly improves its waterproof and seepage-proof performance, ensuring effective protection of internal electrical components in various environments and extending the equipment's service life. The precise bending and welding processes of each connecting section ensure a tight fit between the enclosure components, are easy to process, significantly reduce manufacturing costs, and facilitate overall assembly.
