Description

Technical Field

[0001] This utility model relates to the field of ceiling-mounted air conditioners, and in particular to a fixing structure for a ceiling-mounted air conditioner's drip tray. Background Technology

[0002] Ceiling-mounted units are a common form of embedded central air conditioning. Their core feature is that they achieve concealed air supply through ceiling installation, balancing space utilization and aesthetics. In ceiling-mounted units, the condensate tray is installed below the evaporator to collect and promptly drain the condensate generated during operation. The evaporator itself is located inside the unit's casing.

[0003] The installation of ceiling-mounted air conditioners involves the fixing structure between the drip tray and the air conditioner housing, and existing fixing structures vary widely. Taking the scheme disclosed in CN217540892U as an example, it involves the assembly relationship between the drip tray and the housing. Specifically, in this scheme, the drip tray is nested inside the housing, remaining inside both after assembly and during actual use. This nested structure makes subsequent maintenance and disassembly of the drip tray difficult, and sometimes even damages other internal components of the housing during disassembly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ceiling machine water tray fixing structure that facilitates the removal of the water tray from the housing.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a ceiling machine water receiving tray fixing structure, including a water receiving tray and a shell, the water receiving tray is set on the shell, the top end face of the water receiving tray abuts against the bottom opening end face of the shell, and the water receiving tray and the shell are connected by a detachable connection structure.

[0006] Furthermore, the detachable connection structure includes a water tray buckle and a slot. The water tray buckle is located on the outer side wall of the water tray, and the slot is located on the outer side wall of the housing. The water tray buckle is engaged in the slot.

[0007] Furthermore, the water receiving tray includes a connecting plate, the water receiving tray is snapped onto the connecting plate, the connecting plate is connected to the main body of the water receiving tray through a first connecting beam, and an air outlet is provided between the connecting plate and the main body of the water receiving tray.

[0008] Furthermore, the connection between the first connecting beam and the connecting plate is provided with transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs are perpendicular to the first connecting beam, and the longitudinal reinforcing ribs are perpendicular to the first connecting beam.

[0009] Furthermore, an inner buckle ear is provided on the wall surface of the connecting plate facing the air outlet. The inner buckle ear has a bent structure and extends vertically. It includes filling foam, and the filling foam is fixedly installed on the inner buckle ear.

[0010] Furthermore, the inner-fastening ears are arranged in pairs, and there is an inner-fastening ear reinforcing rib between the pairs of inner-fastening ears. The inner-fastening ear reinforcing rib is arranged in a horizontal direction. A second connecting beam is provided on the wall surface of the connecting plate facing the air outlet. The second connecting beam is arranged parallel to the inner-fastening ear reinforcing rib.

[0011] Furthermore, the water tray buckle includes an upwardly bent structure with guide ribs inside, which guide the water tray buckle into the slot.

[0012] Furthermore, the connecting plate is arranged circumferentially along the outer sidewall of the water receiving tray.

[0013] Furthermore, adjacent connecting plates are connected into a single structure by a third connecting beam.

[0014] Furthermore, the cross-sectional shape of the third connecting beam is I-shaped.

[0015] The beneficial effects of this utility model are: 1. The water tray and the housing are connected via their respective end faces, placing the water tray outside the housing. This not only facilitates disassembly of the water tray but also reduces the risk of damage to internal components during removal. The top end face of the water tray abuts against the bottom opening end face of the housing, ensuring minimal gaps and a good seal. A water tray clip is provided on the outer sidewall of the water tray, and a groove is provided on the outer sidewall of the housing. The clip engages with the groove, allowing for convenient and efficient fixing of the water tray at the housing opening. Subsequent disassembly of the water tray is also very convenient.

[0016] Second, the connecting plate is equipped with inward-facing ears, which can improve the fixing effect of the filling foam. Specifically, the filling foam is cooled and fixed onto the connecting plate directly within the mold, thus ensuring the filling foam is firmly fixed to the connecting plate.

[0017] Third, the second connecting beam and the inner buckle ear reinforcing rib are arranged in parallel, that is, the extension direction of the second connecting beam and the extension direction of the inner buckle ear reinforcing rib are parallel to each other. This arrangement makes the stress on both sides of the inner buckle ear more stable and improves the strength of the inner buckle ear. At the same time, this design also facilitates the demolding and parting of the mold during the manufacturing of the connecting plate.

[0018] Fourth, the adjacent connecting plates are connected into a whole structure by the I-shaped third connecting beam, which effectively improves the overall stability of the connecting plates and also ensures the connection stability after the water receiving tray is fixed to the shell.

[0019] This invention is particularly applicable to the design of a fixed structure for a ceiling-mounted water receiving tray. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figures 1 to 9The ceiling-mounted water collection tray fixing structure shown has a ring-shaped structure. The main body of the water collection tray 1 is a ring-shaped water collection groove with its opening facing upwards, used to collect, gather, and drain the condensate dripping from the top of the water collection tray 1. Figure 1 and Figure 2 As shown, four connecting plates 2 are circumferentially arranged around the main body of the water tray 1. The extension lines of the four connecting plates 2 form a rectangle. Each connecting plate 2 is connected to the main body of the water tray 1 as an integral structure by a first connecting beam 11. The gap between the connecting plate 2 and the main body of the water tray 1 is an air outlet 3, which is also circumferentially arranged around the main body of the water tray 1. Adjacent connecting plates 2 can be connected as an integral structure by guide ribs 22, the cross-sectional shape of which can be I-shaped. Thus, the main body of the water tray 1 and the four connecting plates 2 together constitute a structurally stable integral water tray 1. The outer periphery of the water tray 1 is provided with a recessed step 12 according to installation requirements to avoid the mounting screws after the whole machine is assembled.

[0032] like Figure 3 As shown, a water tray buckle 21 is provided on the outer side of the connecting plate 2. The water tray buckle 21 is a bent structure that bends towards the side of the housing 4. Figure 8 As shown, the water tray clip 21 extends horizontally and is fixedly mounted on the outer wall of the connecting plate 2. Figure 4 As shown, a guide rib 22 is provided inside the bent structure of the water tray buckle 21. The guide rib 22 is vertically arranged on the inner wall of the bent structure, and a gap is left between the guide rib 22 and the connecting plate 2. The slot 43 is set in the gap between the guide rib 22 and the connecting plate 2. The guide rib 22 can be a plate-like structure with a slope. At the opening, the gap between the guide rib 22 and the connecting plate 2 is larger, which is used to fit the side of the slot 43 well. As the side of the slot 43 is inserted into the water tray buckle 21 along the slope, the gap between the slope of the guide rib 22 and the connecting plate 2 becomes smaller and smaller. When the side of the slot 43 is inserted to the limit position, the gap between the slope of the guide rib 22 and the connecting plate 2 also reaches the minimum value, realizing the locking of the slot 43.

[0033] like Figure 4 and Figure 5 As shown, the cross-section of the connecting plate 2 can be I-shaped, that is, formed by the second connecting beam 27, the plate surface on the left side of the second connecting beam 27, and the plate surface on the right side of the second connecting beam 27, thereby improving the structural strength of the connecting plate 2. The connecting part in the middle of the I-shaped connecting plate 2 is the second connecting beam 27. Among the plate surfaces connected on both sides of the second connecting beam 27, the width of the outer plate surface is greater than the width of the inner plate surface, i.e. Figure 4In the middle, the width of the plate on the right side of the second connecting beam 27 is greater than the width of the plate on the left side of the second connecting beam 27. The water tray clip 21 is set on the plate on the right side of the second connecting beam 27. The wall surface on the right side of the second connecting beam 27 facing the air outlet 3 is provided with a pair of inwardly folded ears 23. The inwardly folded ears 23 have a bent structure, and the bending directions of the paired inwardly folded ears 23 are opposite. The inwardly folded ears 23 extend in the vertical direction. The inwardly folded ears 23 are provided with inwardly folded ear reinforcing ribs 24. The inwardly folded ear reinforcing ribs 24 are set in the horizontal direction. The inwardly folded ear reinforcing ribs 24 and the second connecting beam 27 are both set in the horizontal direction, but the inwardly folded ear reinforcing ribs 24 and the second connecting beam 27 are not collinear, that is, they are set at different heights in the horizontal direction. In actual assembly, the filling foam 18 is fixed to the connecting plate 2 of the water tray 1 through the inwardly folded ears 23, wherein the water tray 1 is located between the filling foam 18 and the shell 4. The water receiving tray 1 is equipped with lifting lugs 13 around its outer perimeter for easy hoisting.

[0034] like Figure 6 As shown, one end of the first connecting beam 11 is connected to the wall surface of the connecting plate 2 facing the air outlet 3, and the other end of the first connecting beam 11 is connected to the main body of the water receiving tray 1, i.e., the annular water receiving groove. At the connection between the first connecting beam 11 and the connecting plate 2, transverse reinforcing ribs 25 and longitudinal reinforcing ribs 26 are respectively provided. There are two transverse reinforcing ribs 25, located on the left and right sides of the connection between the first connecting beam 11 and the connecting plate 2. The transverse reinforcing ribs 25 are perpendicular to the first connecting beam 11, and the longitudinal reinforcing ribs 26 are also perpendicular to the first connecting beam 11. Simultaneously, the longitudinal reinforcing ribs 26 are also perpendicular to the transverse reinforcing ribs 25. Thus, although the wall surface of the connecting plate 2 facing the air outlet 3 is mainly supported by the first connecting beam 11, the transverse reinforcing ribs 25 and the longitudinal reinforcing ribs 26 provide necessary support for the connecting plate 2, ensuring its stability, and further providing necessary support for the water receiving tray clip 21 on the connecting plate 2 to engage with the clip groove 43.

[0035] like Figure 7 As shown, the drip tray 1 is provided with a drain outlet 14 for draining the condensate accumulated in the annular drip groove of the drip tray 1. The drip tray 1 is provided with screw posts 16 for providing support when the drip tray 1 is fixed to surrounding components. A power cord guide groove 15 is provided on the inner ring of the annular drip tray 1 for guiding and storing the power cord.

[0036] Figure 8 and Figure 9The diagram shows the assembly of the drip tray 1 and the housing 4. The foam insert 18 is positioned on the inner tab 23 of the connecting plate 2, which is also attached to the drip tray 1. A foolproof marking 17 is provided on the foam insert 18 to prevent incorrect placement during subsequent assembly. Like the drip tray 1, the foam insert 18 has a ring-shaped structure, with the middle section corresponding to the position of the ceiling-mounted unit's fan 41, serving as an air inlet. The slots 43 of the housing 4 correspond one-to-one with the drip tray clips 21. During actual assembly, the drip tray clips 21 are snapped into the slots, ensuring a tight seal between the drip tray 1 and the opening of the housing 4, resulting in a good seal between them. In subsequent use, the condensate from the drip tray 1 is discharged through the drain outlet 14, and the ceiling-mounted unit's power cord is routed and stored through the power cord guide 15. The foam insert 18 provides insulation.
