Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an electrical control box assembly and a wall-mounted air conditioner. Background Technology

[0002] In existing wall-mounted air conditioners, the display component is often integrated into the electrical control box. The control box contains a circuit board, and an opening on its surface exposes the display component. However, during use, a large gap often exists between the display component and the opening in the control box, allowing moisture to easily enter and damage the circuit board. This not only shortens the lifespan of the control box but also poses a significant safety hazard. Summary of the Invention

[0003] The first objective of this invention is to provide an electronic control box assembly to solve the technical problem that there is often a large gap between the opening of the existing display assembly and the electronic control box, which allows moisture to easily enter the inside of the electronic control box and damage the circuit board.

[0004] The present invention provides an electrical control box assembly, comprising an electrical control box and a display structure. The electrical control box has an opening for exposing the display structure, and a waterproof structure is provided between the electrical control box and the display structure. The waterproof structure includes a first water-blocking rib disposed around the opening in the electrical control box, and a second water-blocking rib disposed on the outer periphery of the display structure. In a direction perpendicular to the opening, the second water-blocking rib overlaps with the first water-blocking rib in the portion surrounding the display structure.

[0005] By setting a first water-blocking rib around the opening of the electrical control box and a second water-blocking rib around the outer periphery of the display structure, the overlapping area of ​​the first and second water-blocking ribs in the direction perpendicular to the opening creates a labyrinthine waterproof structure between the outer edge of the display structure and the inner edge of the opening. This effectively reduces the risk of moisture entering the electrical control box, providing a certain degree of protection for the electrical components inside the box. It also extends the service life of the electrical control box and reduces safety hazards.

[0006] Furthermore, the electrical control box includes a box body and a box cover, wherein the opening is disposed on the front wall of the box body, the opening includes an upper edge and a lower edge opposite to each other in the vertical direction, and a first side edge and a second side edge located between the upper edge and the lower edge and opposite to each other, the second side edge being located between the first side edge and the box cover; a portion of the first water-blocking rib is disposed on the box body, and another portion of the first water-blocking rib is disposed on the box cover. By placing a portion of the first water-blocking rib on the box body and another portion of the first water-blocking rib on the box cover, it is possible to facilitate the assembly of the display structure while forming a waterproof structure around the outer periphery of the display structure, avoiding assembly interference of the display structure caused by pre-constructing a ring of first water-blocking ribs around the opening.

[0007] Furthermore, a guide groove is provided along the lower edge, and the guide groove extends along the lower edge. The first water-blocking rib includes the sidewall of the guide groove; the second water-blocking rib includes a sliding edge extending downward from the display structure, the sliding edge being slidably accommodated in the guide groove along the extending direction of the lower edge. This arrangement not only creates a labyrinth seal structure between the lower part of the display structure and the lower edge of the opening, effectively preventing moisture from entering from the lower part of the display structure, but also provides guidance during the installation of the display structure to the electrical control box, thereby improving the assembly efficiency of the display structure.

[0008] Furthermore, the first water-blocking rib also includes a protruding rib disposed on the upper edge, the protruding rib protruding from the front wall; the second water-blocking rib also includes a retaining edge extending upward from the display structure, the retaining edge folding towards the front wall to form a flange, wherein the display structure, the retaining edge, and the flange form an undercut groove, and the protruding rib is accommodated in the undercut groove. This arrangement not only creates a labyrinth seal structure between the upper part of the display structure and the upper edge of the opening, thereby effectively preventing moisture from entering from the upper part of the display structure, but also allows the upper part of the display structure to guide the installation process when installing the display structure to the electrical control box, thereby further improving the assembly efficiency of the display structure.

[0009] Furthermore, the rib is located on the outer surface of the front wall. This arrangement ensures that when the display structure is subjected to pressure, the pressure is transmitted to the control box via the rib, rather than to the electrical components (such as circuit boards) connected to the display structure and located inside the control box, thus providing a certain degree of protection for the electrical components inside the control box.

[0010] Furthermore, a limiting groove is provided along the first side edge, the limiting groove extending along the first side edge with its opening facing the cover. The first water-blocking rib also includes the side wall of the limiting groove. The second water-blocking rib also includes an insertion edge extending from the display structure into the interior of the housing, the insertion edge being inserted into the limiting groove. This arrangement not only allows the display structure to form a labyrinth seal with the control box at the first side edge, effectively preventing moisture from entering from the first side edge, but also allows the sliding stroke of the display structure into the housing to be limited by the contact between the insertion edge and the limiting groove during the assembly of the display structure, avoiding over-assembly of the display structure.

[0011] Furthermore, the first water-retaining rib also includes an assembly edge disposed on the side of the lid facing the box body, and the second water-retaining rib also includes an overlapping edge disposed on the second side edge; along a direction perpendicular to the opening, the assembly edge and the overlapping edge are at least partially opposite. This method of achieving waterproof sealing on the second side edge by utilizing the overlapping area between the assembly edge of the lid and the overlapping edge of the display structure is simple in structure and reduces the manufacturing cost of the lid.

[0012] Furthermore, the display structure includes a base and a floating seat. The base is connected to the circuit board inside the control box, and the floating seat is floatingly mounted on the side of the base facing away from the circuit board. The second water-retaining rib is disposed on the base. This arrangement creates a waterproof seal between the display structure and the control box while also allowing the display structure a certain compression allowance. This ensures that when the control box assembly is installed on the air conditioner unit, the floating seat remains in close contact with the front panel, preventing unclear display results due to gaps between the floating seat and the front panel.

[0013] Furthermore, the second water-retaining rib and the base are integrally formed. This design saves on the number of parts to improve assembly efficiency while ensuring the structural strength of the connection between the second water-retaining rib and the base, thereby extending the service life of the base. And / or, the base is snapped into the circuit board. This design not only achieves a detachable connection between the display structure and the circuit board, facilitating disassembly and maintenance of the display structure, but also enables rapid assembly of the display structure and the circuit board, resulting in high assembly efficiency. And / or, the floating seat is snapped into the base. This design not only achieves a detachable connection between the floating seat and the base, facilitating disassembly and maintenance of the floating seat, but also enables rapid assembly of the floating seat and the circuit board, resulting in high assembly efficiency.

[0014] The second objective of this invention is to provide a wall-mounted air conditioner that solves the technical problem that there is often a large gap between the opening of the existing display component and the electrical control box, which allows moisture to easily enter the electrical control box and damage the circuit board.

[0015] The air conditioner wall unit provided by the present invention includes a body and the aforementioned electrical control box assembly, wherein the electrical control box assembly is installed inside the body; the body includes a front panel, wherein the front panel is provided with a display area opposite to the display assembly.

[0016] By incorporating the aforementioned electrical control box assembly into the wall-mounted air conditioner, the air conditioner gains all the advantages of the aforementioned electrical control box assembly, which will not be elaborated upon here. Attached Figure Description

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] Figure 1 This is an exploded view of the electrical control box assembly provided in this embodiment; Figure 2 This is a longitudinal sectional view of the electrical control box assembly provided in this embodiment; Figure 3 for Figure 2 A magnified view of the local structure at point A in the middle. (See image below.) Figures 1 to 3 As shown, this embodiment provides an electronic control box assembly, including an electronic control box 100 and a display structure 200. Specifically, the electronic control box 100 has an opening 130 for the display structure 200 to be exposed, and a waterproof structure 300 is provided between the electronic control box 100 and the display structure 200. The waterproof structure 300 includes a first water-blocking rib 310 disposed around the opening 130 in the electronic control box 100, and a second water-blocking rib 320 disposed on the outer periphery of the display structure 200. In the direction perpendicular to the opening 130, the second water-blocking rib 320 overlaps with the first water-blocking rib 310 in the part surrounding the display structure 200.

[0037] In this embodiment, the aforementioned "direction perpendicular to opening 130" can be determined by... Figure 2 and Figure 3The direction indicated by the middle arrow S is...

[0038] By setting a first water-blocking rib 310 around the opening 130 in the control box 100 and a second water-blocking rib 320 around the display structure 200, the overlapping area of ​​the first water-blocking rib 310 and the second water-blocking rib 320 in the direction perpendicular to the opening 130 forms a labyrinth-shaped waterproof structure 300 between the outer edge of the display structure 200 and the inner edge of the opening 130. This effectively reduces the risk of moisture entering the control box 100 and provides a certain degree of protection for the electrical components inside the control box 100. It also extends the service life of the control box 100 and reduces safety hazards.

[0039] Please continue to refer to Figure 1 In this embodiment, the electrical control box 100 includes a box body 110 and a box cover 120. Specifically, an opening 130 is disposed on the front wall 111 of the box body 110. The opening 130 includes an upper edge 131 and a lower edge 132 that are opposite each other in the vertical direction, and a first side edge and a second side edge 134 that are located between the upper edge 131 and the lower edge 132 and opposite each other. The second side edge 134 is located between the first side edge 133 and the box cover 120. A portion of the first water-blocking ribs 310 are disposed on the box body 110, and another portion of the first water-blocking ribs 310 are disposed on the box cover 120.

[0040] When the display structure 200 is installed in the opening 130 of the housing 110, a portion of the second water-blocking rib 320 on the display structure 200 first engages with the first water-blocking rib 310 on the housing 110 to prevent moisture from entering the interior of the control box 100 through the gap between the display structure 200 and the housing 110. Then, after the cover 120 is installed on the housing 110, the first water-blocking rib 310 on the cover 120 engages with the remaining portion of the second water-blocking rib 320 on the display structure 200 to prevent moisture from entering the interior of the control box 100 through the gap between the display structure 200 and the cover 120. Thus, by utilizing the first water-blocking ribs 310 on both the housing 110 and the cover 120, and engaging with the second water-blocking rib 320 on the outer periphery of the display structure 200, a waterproof structure 300 is formed between the display structure 200 and the control box 100.

[0041] By placing a portion of the first water-blocking ribs 310 on the housing 110 and another portion on the cover 120, it is possible to assemble the display structure 200 while forming a waterproof structure 300 around the outer periphery of the display structure 200, thus avoiding assembly interference of the display structure 200 caused by constructing a ring of first water-blocking ribs 310 around the outer periphery of the opening 130 in advance.

[0042] Please continue to refer to Figure 2 and Figure 3In this embodiment, a guide groove 311 is provided at the lower edge 132 of the opening 130. Specifically, the guide groove 311 extends along the lower edge 132, and the first water-blocking rib 310 includes the groove sidewall of the guide groove 311. The second water-blocking rib 320 includes a sliding edge 321 extending downward from the display structure 200, wherein the sliding edge 321 is used to slide and accommodate in the guide groove 311 along the extension direction of the lower edge 132.

[0043] Please continue to refer to Figure 3 In the assembled state of the display structure 200, the sliding edge 321 extending downward from the display structure 200 is accommodated in the guide groove 311 opened in the housing 110. This arrangement ensures that when moisture is present in the lower part of the display structure 200, the moisture flows first to the right to the position of the sliding edge 321, then downward along one side wall of the guide groove 311 into the guide groove 311, and then upward along the other side wall of the guide groove 311, before finally flowing further to the right into the interior of the control box 100. This arrangement creates a labyrinth seal between the lower part of the display structure 200 and the lower edge 132 of the opening 130, effectively preventing moisture from entering from the lower part of the display structure 200.

[0044] In addition, this form of forming a partial waterproof structure 300 by utilizing the sliding edge 321 and the guide groove 311 to accommodate and cooperate also allows the lower part of the display structure 200 to guide the installation process of the display structure 200 when it is installed into the electrical control box 100, thereby improving the assembly efficiency of the display structure 200.

[0045] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the first water-blocking rib 310 may further include a protruding rib 312 disposed on the upper edge 131 of the opening 130, the protruding rib 312 protruding from the front wall 111 of the box body 110; the second water-blocking rib 320 may further include a baffle 322 extending upward from the display structure 200, the baffle 322 being folded towards the front wall 111 to form a flange 323, wherein the display structure 200, the baffle 322 and the flange 323 form an undercut groove, and the protruding rib 312 is accommodated in the undercut groove.

[0046] Please continue to refer to Figure 3 When moisture is present on the upper part of the display structure 200, the moisture flows downwards to the position of the rib 312, then flows to the left along the rib 312 to the baffle 322, then flows downwards along the baffle 322, and further flows to the right along the rib 312 before entering the interior of the control box 100. This arrangement also forms a labyrinth seal between the upper part of the display structure 200 and the upper edge 131 of the opening 130, effectively preventing moisture from entering from the upper part of the display structure 200.

[0047] In addition, this form of using the rib 312 and the undercut groove to form a waterproof structure 300 also allows the upper part of the display structure 200 to guide the installation process of the display structure 200 when it is installed into the electrical control box 100, thereby further improving the assembly efficiency of the display structure 200.

[0048] Please continue to refer to Figure 3 In this embodiment, the rib 312 is located on the outer surface of the front wall 111. That is, the rib 312 is disposed on the surface of the front wall 111 that is away from the inner cavity of the electrical control box 100.

[0049] By placing the protruding rib 312 at the aforementioned position, the inverted groove on the upper part of the display structure 200 engages with the protruding rib 312 on the outside of the electrical control box 100. This not only provides effective waterproofing but also ensures that when the display structure 200 is subjected to pressure, the pressure is transmitted to the electrical control box 100 through the protruding rib 312, rather than to the electrical components (such as the circuit board 400) connected to the display structure 200 and located inside the electrical control box 100. This provides a certain degree of protection for the electrical components inside the electrical control box 100.

[0050] Figure 4 This is a cross-sectional view of the electrical control box assembly provided in this embodiment; Figure 5 for Figure 4 A magnified view of the local structure at point B. (See image below.) Figure 4 and Figure 5 As shown, a limiting groove 313 is provided along the first side edge 133, the limiting groove 313 extends along the first side edge 133, and the opening of the limiting groove 313 faces the cover 120. The first water-blocking rib 310 also includes the side wall of the limiting groove 313. The second water-blocking rib 320 also includes an insertion edge 324 extending from the display structure 200 into the interior of the box body 110, wherein the insertion edge 324 is inserted into the limiting groove 313.

[0051] Please continue to refer to Figure 5 When moisture is present at the first side edge 133 of the display structure 200, the moisture flows downwards to one side wall of the limiting groove 313, then flows to the right along that side wall, and downwards into the interior of the limiting groove 313. Subsequently, it flows downwards along the insertion edge 324, and further to the right along the other side wall of the limiting groove 313 before entering the interior of the control box 100. This arrangement ensures that the display structure 200 at the first side edge 133 also forms a labyrinth seal with the control box 100, effectively preventing moisture from entering from the first side edge 133.

[0052] In addition, this form of forming a partial waterproof structure 300 by using the insertion state of the insertion edge 324 and the limiting groove 313 also allows the sliding stroke of the display structure 200 into the housing 110 to be limited by the abutment of the insertion edge 324 and the limiting groove 313 during the assembly process of the display structure 200, thereby avoiding over-assembly of the display structure 200.

[0053] Please continue to refer to Figure 1 and Figure 5 In this embodiment, the first water-blocking rib 310 may further include an assembly edge 314 disposed on the side of the cover 120 facing the box body 110, and the second water-blocking rib 320 may further include an overlapping edge 325 disposed on the second side edge 134, wherein, along the direction perpendicular to the opening 130, the assembly edge 314 and the overlapping edge 325 are at least partially opposite to each other.

[0054] This method of achieving waterproof sealing along the second side edge 134 by utilizing the overlapping area between the mounting edge 314 of the cover 120 and the overlapping edge 325 of the display structure 200 is simple in structure and reduces the manufacturing cost of the cover 120.

[0055] Please continue to refer to Figure 5 In this embodiment, when the cover 120 and the body 110 are assembled, the assembly edge 314 is located in front of the overlapping edge 325, that is, the assembly edge 314 is located on the side of the overlapping edge 325 that is away from the inner cavity of the control box 100.

[0056] This configuration ensures that after the cover 120 is assembled onto the body 110, the assembly edge 314 of the cover 120 forms a limit on the overlapping edge 325 in front, preventing the display structure 200 from coming out forward at the second side edge 134 position, thus ensuring the assembly stability of the display structure 200.

[0057] Figure 6 A longitudinal sectional view of the display structure 200 of the electrical control box assembly provided in this embodiment mounted on the circuit board 400; Figure 7 for Figure 6 Enlarged view of the local structure at point C; Figure 8 This is one of the exploded structural diagrams of the display structure 200 and circuit board 400 of the electronic control box assembly provided in this embodiment; Figure 9 This is the second exploded view of the display structure 200 and circuit board 400 of the electronic control box assembly provided in this embodiment. Please continue to refer to... Figure 3 and Figure 5 and combined Figures 6 to 9 In this embodiment, the display structure 200 may include a base 210 and a floating seat 220. The base 210 is connected to the circuit board 400 inside the control box 100, and the floating seat 220 is floatingly mounted on the side of the base 210 away from the circuit board 400. The second water-blocking rib 320 is disposed on the base 210.

[0058] This design creates a waterproof seal between the display structure 200 and the control box 100, while also providing the display structure 200 with a certain compression margin. This ensures that when the control box assembly is installed on the air conditioner unit, the floating seat 220 remains in contact with the front panel, preventing unclear display results due to gaps between the floating seat 220 and the front panel.

[0059] It should be noted that the above-mentioned "second water-blocking rib 320 is set on base 210" specifically means that the sliding edge 321, the blocking edge 322, the flange 323, the plug edge 324 and the overlapping edge 325 are all set on base 210.

[0060] Please continue to refer to Figure 8 and Figure 9 In this embodiment, the floating seat 220 can be mounted on the base 210 by a spring to achieve its floating function relative to the base 210.

[0061] In this embodiment, the second water-blocking rib 320 and the base 210 are integrally formed.

[0062] By setting the second water-blocking rib 320 and the base 210 as an integrally formed structure, the number of parts is reduced to improve assembly efficiency, while the structural strength of the connection between the second water-blocking rib 320 and the base 210 is guaranteed, thereby extending the service life of the base 210.

[0063] Please continue to refer to Figure 7 In this embodiment, the base 210 is snapped into the circuit board 400.

[0064] By snapping the base 210 onto the circuit board 400, a detachable connection between the display structure 200 and the circuit board 400 is achieved, facilitating the disassembly and maintenance of the display structure 200. Furthermore, it enables rapid assembly of the display structure 200 and the circuit board 400, resulting in high assembly efficiency.

[0065] Specifically, please continue to refer to Figure 7 and Figure 9 Multiple first buckles 211 can be arranged in a dispersed manner on the base 210. Correspondingly, multiple first holes are provided on the circuit board 400 that correspond one-to-one with the multiple first buckles 211. The base 210 is fixed on the circuit board 400 by the snap-fit ​​cooperation between the first buckles 211 and the first holes.

[0066] Please continue to refer to Figure 7 In this embodiment, the floating seat 220 is snapped into the base 210.

[0067] By snapping the floating seat 220 onto the base 210, a detachable connection between the floating seat 220 and the base 210 is achieved, facilitating the disassembly and maintenance of the floating seat 220. Furthermore, it enables the rapid assembly of the floating seat 220 and the circuit board 400, resulting in high assembly efficiency.

[0068] Specifically, please continue to refer to Figure 7 and Figure 9 Multiple second buckles 221 can be provided in a dispersed manner on the floating seat 220. Correspondingly, multiple second locking holes are provided on the base 210 that correspond one-to-one with the above-mentioned multiple second buckles 221. The floating seat 220 is fixed on the base 210 by the snap-fit ​​cooperation between the second buckles 221 and the second locking holes.

[0069] Figure 10 This is an assembly diagram of the electrical control box assembly provided in an embodiment of the present invention. Figure 10 As shown, in this embodiment, the assembly process of the electrical control box assembly is as follows: First, referring to (a), the grounding plate 500 and the pressure plate 600 are installed onto the box body 110 so that the grounding plate 500, the pressure plate 600, and the box body 110 are as a whole. At the same time, referring to (b), the floating seat 220 is snapped together with the base 210, and the base 210 is snapped together with the circuit board 400, wherein the spring is located between the floating seat 220 and the base 210. At this time, the display structure 200 and the circuit board 400 are as a whole. Second, referring to (c), the circuit board 400, together with the display structure 200 mounted on the circuit board 400, is slidably inserted into the box body 110 from the opening of the box body 110. During this process, the lower part of the display structure 200... The sliding edge 321 slides into the guide groove 311 of the lower edge 132 of the opening 130, and the undercut groove formed by the retaining edge 322 and the flange 323 on the upper part of the display structure 200 slides into the protruding rib 312 of the upper edge 131 of the opening 130. As the circuit board 400 continues to slide into the housing 110, the circuit board 400 is assembled in place after the lateral insertion edge 324 of the display structure 200 enters the limiting groove 313 of the first lateral edge 133 of the opening 130. Finally, please refer to (c) to assemble the cover 120 into the housing 110. After the cover 120 is assembled in place in the housing 110, the assembly edge 314 of the cover 120 is located in front of the overlapping edge 325 of the display structure 200. The electrical control box assembly is completed as shown in (d). At this point, a labyrinth waterproof structure 300 is formed on the outer periphery of the display structure 200.

[0070] In addition, this embodiment also provides a wall-mounted air conditioner, including a body and the above-mentioned electrical control box assembly, wherein the electrical control box assembly is installed inside the body; the body includes a front panel, and the front panel is provided with a display area opposite to the display assembly.

[0071] By incorporating the aforementioned electrical control box assembly into the wall-mounted air conditioner, the air conditioner gains all the advantages of the aforementioned electrical control box assembly, which will not be elaborated upon here.

[0072] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
