Description

Technical Field

[0001] This utility model relates to a sealing plate for the copper pipe connection area of ​​a ceiling-mounted air conditioner and a ceiling-mounted air conditioner indoor unit, belonging to the field of air conditioner technology. Background Technology

[0002] In current ceiling-mounted air conditioning units, the lower surface of the panel forms the exterior of the indoor unit. For aesthetic purposes, these panels are typically designed symmetrically. However, the indoor unit has copper pipes that connect to the outdoor unit, making symmetry impossible. The main unit casing includes at least side panels and a bottom panel. The outer perimeter of the side panels has a recessed area projected horizontally, and the vertical space corresponding to this recess is the copper pipe connection area. This creates a significant gap when the main unit casing and panel are fitted together. The panel usually has four air outlets along its outer perimeter, one on each side. Through the air outlets near the copper pipe connection area, the various connection structures of the copper pipes and the ceiling above them are visible, affecting the overall appearance of the indoor unit. Furthermore, during operation, condensation on the outer surface of the copper pipes usually leaks out through this gap, impacting the user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sealing plate for the copper pipe connection area of ​​the ceiling-mounted indoor unit, which can effectively solve the local sealing problem of the copper pipe connection area of ​​the ceiling-mounted indoor unit and reduce the risk of condensation water generated on the outer surface of the copper pipe flowing out.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sealing plate for the copper pipe connection area of ​​a ceiling machine, including a horizontally arranged sealing base plate, a fixed mounting plate extending vertically is fixedly arranged on at least one side of the upper surface of the sealing base plate, the outer side of the fixed mounting plate is used to fit and be fixedly connected with the outer shell side plate of the copper pipe connection area, and a first flange is provided on the upper surface edge of the sealing base plate in the area where the fixed mounting plate is not provided, and the inner side of the first flange, the inner side of the fixed mounting plate and the upper surface of the sealing base plate are combined to form a water storage cavity.

[0005] To make the structure simple, reliable, and easy to implement, a further preferred embodiment is that the fixed mounting plate includes a first sealing side plate and a second sealing side plate connected as a whole, and the first sealing side plate and the second sealing side plate are respectively provided with bolt connection holes for fixed connection with the outer shell side plate.

[0006] To make the structure simple, reliable and easy to implement, a further preferred embodiment is that the outer sides of the first sealing side plate and the outer sides of the second sealing side plate are respectively fixedly provided with positioning hooks for engaging and connecting with the outer shell side plate; the positioning hooks include a transverse connecting part and a hook part, the hook part is bent relative to the transverse connecting part in a direction away from the sealing base plate, and the hook part has a first guide slope at its outer end on the side facing the fixed mounting plate.

[0007] To make the structure simple, reliable, and easy to implement, a further preferred option is that the upper end of the first sealing side plate is provided with a first copper pipe engaging and positioning arc groove and a second copper pipe engaging and positioning arc groove arranged at intervals.

[0008] To facilitate assembly, a further preferred embodiment is that the vertical distance between the bottom of the first copper tube engaging and positioning arc groove and the upper surface of the sealing base plate is smaller than the vertical distance between the bottom of the second copper tube engaging and positioning arc groove and the upper surface of the sealing base plate. The inner wall of the first copper tube engaging and positioning arc groove on the side closest to the second copper tube engaging and positioning arc groove smoothly connects with the outer end face of the second copper tube engaging and positioning arc groove through the second guide slope.

[0009] To further improve structural reliability, a preferred embodiment is that the vertical side of the first sealing side plate away from the second sealing side plate has a second flange that is bent toward the center of the sealing base plate, and a first reinforcing rib is provided at the connection between the second flange and the first flange.

[0010] To further facilitate assembly, the preferred embodiment is that the outer side of the first sealing side plate is provided with a recessed through hole, and a rubber wire guide is snapped and fixed in the recessed through hole. The outer periphery of the rubber wire guide has a snap-fit ​​and fixing groove with a U-shaped cross section, and the middle part of the rubber wire guide has a wire through hole.

[0011] To further improve structural reliability, a preferred solution is to provide several second reinforcing ribs on the upper surface of the sealing base plate.

[0012] To further improve structural reliability and facilitate assembly, a preferred solution is to fix a lining positioning rib on the lower surface of the sealing base plate at its edge.

[0013] Accordingly, this utility model also provides a ceiling-mounted indoor unit with the aforementioned sealing plate for the copper pipe connection area of ​​the ceiling-mounted unit, including a decorative panel and a main unit housing. The decorative panel is fixedly disposed at the bottom of the main unit housing. The main unit housing includes a housing side plate and a housing bottom plate.

[0014] To further improve structural reliability and reduce the risk of condensation leakage from the outer surface of the copper pipe, a preferred solution is that the lower surface of the sealing base plate and the upper surface of the face panel are connected by a first gasket, and the lower surface of the outer shell base plate and the upper surface of the face panel are connected by a second gasket. The arrangement of the first and second gaskets is designed so that when water accumulated inside the water storage cavity of the sealing plate in the copper pipe connection area of ​​the skylight machine overflows from the top of the water storage cavity, it can be absorbed by the first and second gaskets.

[0015] The beneficial effects of this utility model are as follows: The sealing base plate can effectively shield the copper pipe connection area. Only the lower surface of the sealing base plate (or the first gasket) is visible through the air outlet near the copper pipe connection area. Various connection structures in the copper pipe connection area and the ceiling above it are not visible, improving the overall appearance of the ceiling-mounted indoor unit. Furthermore, during operation, condensation on the outer surface of the copper pipes can be collected through a water storage cavity formed on the upper surface of the sealing base plate, reducing the risk of condensation leakage and improving user experience. In the preferred embodiment, when water accumulated inside the water storage cavity of the sealing plate in the copper pipe connection area overflows from the top of the cavity, it can be absorbed by the first and second gaskets, further reducing the risk of condensation leakage and essentially eliminating the problem.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 5 As shown, the sealing plate for the copper pipe connection area of ​​the ceiling machine described in this utility model includes a horizontally arranged sealing base plate 11. At least one side of the upper surface of the sealing base plate 11 is fixedly provided with a vertically extending fixing mounting plate. The outer side of the fixing mounting plate is used to fit and fixably connect with the outer shell side plate 31 of the copper pipe connection area, which is equivalent to the fixing mounting plate being provided with an outer shell side plate fixing connection structure for fixing and connecting the outer shell side plate 31. It can be understood that there can be a variety of fixing connection methods between the fixing mounting plate and the outer shell side plate 31, such as bolt connection, snap-fit ​​connection, a combination of bolt connection and pin connection, or a combination of bolt connection and snap-fit ​​connection, etc.

[0027] The upper surface edge of the sealing base plate 11 is provided with a first flange 12 in the area where no fixed mounting plate is provided. The inner side of the first flange 12, the inner side of the fixed mounting plate, and the upper surface of the sealing base plate 11 are combined to form a water storage cavity. That is, the first flange 12 and the fixed mounting plate form an annular rim, and the annular rim is closed and connected to the upper surface of the sealing base plate 11. In a preferred embodiment, the first flange 12, the fixed mounting plate, and the sealing base plate 11 are usually an integral structure.

[0028] To ensure a simple, reliable, and easy-to-implement structure, in some preferred embodiments, the mounting plate includes a first sealing side plate 13 and a second sealing side plate 14 integrally connected. The first sealing side plate 13 and the second sealing side plate 14 are preferably connected via an arc-shaped connecting portion. The first sealing side plate 13 and the second sealing side plate 14 are each provided with bolt connection holes 15 for fixed connection with the outer casing side plate 31. This allows the mounting plate to form a larger contact surface with the outer casing side plate 31, improving the overall structural reliability. Using bolt connections simplifies assembly. More specifically, screw connections can be used, meaning the outer casing side plate 31 is provided with connecting studs corresponding to the bolt connection holes 15, and the connecting studs have internal threaded holes adapted to the screws.

[0029] To reduce the number of screw connections while ensuring structural reliability, in a further preferred embodiment, the outer surfaces of the first sealing side plate 13 and the second sealing side plate 14 are respectively fixedly provided with positioning hooks 16 for engaging with the outer shell side plate 31. This generally requires only one screw connection structure on each of the first and second sealing side plates 13 and one positioning hook 16 on each. Correspondingly, the outer shell side plate 31 is provided with a connecting hole 33 for matching the positioning hook 16. For further ease of assembly, the positioning hook 16 includes a transverse connecting portion and a hook portion 161. The hook portion 161 is bent away from the sealing base plate 11 relative to the transverse connecting portion, and a first guide slope 162 is provided at its outer end on the side of the hook portion facing the fixed mounting plate. (See reference...) Figures 6 to 8 When assembling the ceiling-mounted indoor unit, the outer casing base plate 32 is usually facing upwards. Correspondingly, the sealing plate 1 in the copper pipe connection area of ​​the ceiling-mounted unit has its lower surface of the sealing base plate 11 facing upwards. At this time, the hook portion 161 of the positioning hook 16 is bent downwards relative to the transverse connection portion. The positioning hook 16 is inserted into the connecting hole 33 in the form of a hanging hook. After the positioning hook 16 is in place, the two screws corresponding to the bolt connecting holes 15 are then tightened. To further facilitate assembly, the width of the connecting hole 33 decreases gradually from the end closest to the outer casing base plate 32 to the end furthest from the outer casing base plate 32. Figure 6 As shown, the width of the connecting hole 33 decreases from top to bottom. The upper end of the connecting hole 33 is wider, facilitating the insertion of the positioning hook 16, while the lower end is relatively narrower (matching the width of the positioning hook 16), effectively limiting its position. The connection between the positioning hook 16 and the connecting hole 33 also serves as a pre-positioning mechanism, facilitating subsequent screw connection and fixation.

[0030] To make the structure simple, reliable and easy to implement, in some preferred embodiments, the upper end of the first sealing side plate 13 is provided with a first copper pipe engaging and positioning arc groove 17 and a second copper pipe engaging and positioning arc groove 18 arranged at intervals. The first copper pipe engaging and positioning arc groove 17 and the second copper pipe engaging and positioning arc groove 18 correspond one-to-one with the two copper pipes 4, and a semi-circular groove structure can usually be adopted. The first copper pipe engaging and positioning arc groove 17 and the second copper pipe engaging and positioning arc groove 18 correspond to the positions of the two copper pipes 4. Typically, the vertical height of the connecting ends of the two copper pipes 4 is different. Correspondingly, the vertical height of the first copper pipe engaging and positioning arc groove 17 and the second copper pipe engaging and positioning arc groove 18 is also different. That is, the vertical distance between the bottom of the first copper pipe engaging and positioning arc groove 17 and the upper surface of the sealing base plate 11 is less than the vertical distance between the bottom of the second copper pipe engaging and positioning arc groove 18 and the upper surface of the sealing base plate 11. For ease of assembly, the inner wall of the first copper pipe engaging and positioning arc groove 17 on the side closest to the second copper pipe engaging and positioning arc groove 18 smoothly connects to the outer end face of the second copper pipe engaging and positioning arc groove 18 via the second guide slope 19. The angle between the second guide slope 19 and the vertical direction is... Figure 3 The value of a is generally around 20°.

[0031] To further improve structural reliability, in some preferred embodiments, the vertical side of the first sealing side plate 13 away from the second sealing side plate 14 has a second flange 110 bent towards the center of the sealing base plate 11. A first reinforcing rib 111 is provided at the connection between the second flange 110 and the first flange 12. The second flange 110, the first flange 12, the first reinforcing rib 111, the mounting plate, and the sealing base plate 11 are typically designed as a single unit. The second flange 110 and the first flange 12 can also serve as gripping points, facilitating employee installation and after-sales disassembly.

[0032] To further facilitate assembly, the copper pipe connection area is often also used as the wiring area for electrical circuits. Accordingly, in some preferred embodiments, the outer surface of the first sealing side plate 13 is provided with a recessed through hole 112 (i.e., the recessed portion of the recessed through hole 112 is located on the side of the first sealing side plate 13 facing away from the water storage chamber). A rubber wire guide 113 is snapped and fixedly installed inside the recessed through hole 112. The outer periphery of the rubber wire guide 113 has a U-shaped snap-fit ​​groove, and the middle part of the rubber wire guide 113 has a wire through hole. The recessed portion of the recessed through hole 112 is used to accommodate the snap-fit ​​end of one axial end of the rubber wire guide 113 to avoid affecting the fit between the outer surface of the first sealing side plate 13 and the outer shell side plate 31. That is, one side wall of the snap-fit ​​groove of the rubber wire guide 113 is used to abut against the bottom wall of the recessed portion, and the other side wall abuts against the inner end face of the recessed through hole 112 (i.e., the inner surface of the first sealing side plate 13). In a preferred embodiment, the rubber wire guide 113 has a cross-shaped wire through hole at its center. Relying on the elastic deformation capability of the rubber wire guide 113 itself, the wire can pass through easily while ensuring the sealing of the wire passage area. In a preferred embodiment, the wire is generally led out from the wire clamping member 5 inside the main unit, and then passes through the clearance hole on the side plate 31 of the outer casing and the corresponding wire through hole on the rubber wire guide 113 in sequence.

[0033] To further improve structural reliability, in some preferred embodiments, the upper surface of the sealing base plate 11 is provided with a plurality of second reinforcing ribs 114. In preferred embodiments, the second reinforcing ribs 114 are generally composed of a plurality of transverse ribs and longitudinal ribs, forming an integral structure relative to the upper surface of the sealing base plate 11.

[0034] To further improve structural reliability and facilitate assembly, in some preferred embodiments, a gasket positioning rib 115 is fixedly provided on the lower surface of the sealing base plate 11 at its edge. The lower surface of the sealing base plate 11 is the outer surface of the side facing away from the water storage cavity. The lower surface of the sealing base plate 11 can generally be composed of a first strip and a second strip connected as a whole, with a rounded corner structure connecting the first strip and the second strip. The extension directions of the first strip and the second strip correspond to the length and width directions of the sealing base plate 11, respectively, which can effectively position the first gasket. The first gasket can serve as a heat insulation function and also eliminate the assembly gap between the lower surface of the sealing base plate 11 and the upper surface of the faceplate 2, thereby improving structural reliability. The shape of the sealing base plate 11 is usually adapted to the shape of the concave area formed by the projection of the outer peripheral surface of the outer shell side plate 31 on the horizontal plane. The sealing base plate 11 is generally a quadrilateral with rounded corners. Two of its sides correspond to the first sealing side plate 13 and the second sealing side plate 14, respectively. The extension direction of another side corresponds to the first main side plate 311 of the outer shell side plate 31, and the extension direction of yet another side corresponds to the outer shell transition side plate 312 of the outer shell side plate 31.

[0035] Further reading Figures 6 to 8 This utility model also provides a ceiling-mounted indoor unit with the aforementioned sealing plate for the copper pipe connection area of ​​the ceiling-mounted unit, including a decorative panel 2 and a main unit housing 3. The decorative panel 2 is fixedly installed at the bottom of the main unit housing 3. The main unit housing 3 includes a housing side plate 31 and a housing bottom plate 32. The outer peripheral surface of the housing side plate 31 has a recessed area in the horizontal projection. The vertical space corresponding to the recessed area is the copper pipe connection area. The aforementioned sealing plate 1 for the copper pipe connection area of ​​the ceiling-mounted unit is provided in the copper pipe connection area. The lower surface of the sealing bottom plate 11 and the upper surface of the decorative panel 2 form a clearance fit or are connected through a first gasket. Preferably, the lower surface of the sealing bottom plate 11 and the upper surface of the decorative panel 2 are connected through a first gasket.

[0036] To further improve structural reliability and reduce the risk of condensation leakage from the outer surface of the copper pipe, a preferred solution is that the lower surface of the sealing base plate 11 and the upper surface of the decorative panel 2 are connected by a first gasket, and the lower surface of the outer casing base plate 32 and the upper surface of the decorative panel 2 are connected by a second gasket. The arrangement of the first and second gaskets is designed so that when water accumulated inside the water storage chamber of the sealing plate 1 in the copper pipe connection area of ​​the skylight overflows from the top of the water storage chamber, it can be absorbed by the first and second gaskets. It can be understood that as long as the first gasket covers as much of the lower surface of the sealing base plate 11 as possible, and the second gasket has a portion of its structure located in the outer periphery of the sealing base plate 11, it can effectively prevent condensation leakage from the copper pipe. The second gasket also helps to eliminate the assembly gap between the lower surface of the outer casing base plate 32 and the upper surface of the decorative panel 2, and provides a certain degree of vibration damping, further improving structural reliability.
