Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to drainage devices and air conditioners. Background Technology

[0002] Because air conditioners generate condensation due to the alternating heating and cooling inside, a water intake and drainage system is essential. Traditional air conditioners typically have a drip tray under the evaporator to collect the condensate above it, which is then drained through a drain pipe. A separate base is installed at the bottom of the unit to collect condensate below the drip tray, thus comprehensively collecting the condensate inside the air conditioner. Furthermore, marine air conditioners operate under prolonged tilting and rolling conditions. Therefore, to prevent the drainage from being affected by this environment, drain outlets are provided on both the left and right sides of the drip tray and the base. This allows the drainage system to drain from either side, making it suitable for the tilting and rolling environment on the water.

[0003] Therefore, marine air conditioners have multiple drain outlets, and each drain outlet requires a corresponding drain pipe. The installation of the drain pipes is labor-intensive and has low assembly efficiency. Summary of the Invention

[0004] This invention addresses the problem of the large workload involved in installing drainage pipes for marine air conditioners by proposing a drainage device and an air conditioner that can effectively reduce the workload of drainage pipe installation.

[0005] A drainage device, the drainage device comprising:

[0006] The first water-collecting basin has a first water-collecting space;

[0007] The second water collection tray is located below the first water collection tray along the first direction and has a second water collection space; and

[0008] A connecting mechanism is provided between the first water collection tray and the second water collection tray, and connects the first water collection space and the second water collection space.

[0009] The second water collection tray has a drain outlet that communicates with the second water collection space.

[0010] The aforementioned drainage device is applied to an air conditioner. A first water collection tray has a first water collection space, and a second water collection tray has a second water collection space. Both the first and second water collection spaces can respectively collect condensate dripping from above. The drainage device also includes a connecting mechanism that connects the first and second water collection trays and communicates with both water collection spaces. The second water collection tray has a drain outlet communicating with its second water collection space. Thus, condensate collected in the first water collection space enters the second water collection space through the connecting mechanism, and the condensate in the first water collection space converges into the second water collection space. Finally, the converged condensate flows out from the drain outlet of the second water collection tray. Therefore, it is unnecessary to install a drain outlet or drainage pipe on the first water collection tray; only a drain outlet needs to be installed on the second water collection tray, and corresponding drainage pipes need to be installed for each outlet. This reduces the number of drain outlets and thus the amount of drainage pipe installation, improving assembly efficiency.

[0011] In one embodiment, the connecting mechanism includes a first connecting component and a second connecting component, the first connecting component and the second connecting component being distributed at a distance from each other along a second direction intersecting the first direction, and both the first connecting component and the second connecting component being connected to the first water accumulation space and the second water accumulation space;

[0012] Furthermore, the drain outlet includes a first drain outlet and a second drain outlet, both of which are connected to the second water accumulation space, and the first drain outlet and the second drain outlet are distributed along the second direction.

[0013] In one embodiment, a groove is formed on the top surface of the second water collection tray facing the first water collection tray to form the second water collection space, and the ends of the first connecting component and the second connecting component facing away from the first water collection tray are both connected to the groove.

[0014] In one embodiment, the groove extends in a direction parallel to the second direction, and the first drain outlet and the second drain outlet are respectively connected to opposite ends of the groove in the second direction.

[0015] In one embodiment, the top surface of the second water collection tray includes a first guide surface and a second guide surface, the first guide surface and the second guide surface are respectively located on opposite sides of the groove along a third direction intersecting the second direction, and the first guide surface and the second guide surface are respectively inclined downward in the direction of mutual approach.

[0016] In one embodiment, the angle between the first guide surface and the first direction is in the range of 84 degrees to 88 degrees;

[0017] The angle between the second guide surface and the first direction is in the range of 84 degrees to 88 degrees.

[0018] In one embodiment, both the first connecting component and the second connecting component include a connecting pipe and a manifold. One end of the connecting pipe is connected to the first water collection tray, and the manifold is connected between the other end of the connecting pipe and the second water collection tray. The manifold also connects the connecting pipe to the drain outlet.

[0019] In one embodiment, the manifold is a tee pipe with a first opening, a second opening and a third opening that are interconnected. The connecting pipe is connected between the first opening and the first water receiving tray, the second opening is connected to the groove, and the third opening is connected to the drain outlet.

[0020] An air conditioner includes the aforementioned drainage device.

[0021] In one embodiment, the device includes an evaporator and a compressor arranged along the first direction, with a first water collection tray located between the evaporator and the compressor, and a second water collection tray located on the side of the compressor opposite to the second water collection tray.

[0032] Please see Figures 1-3 In one embodiment of the present invention, an air conditioner 100 is provided, including an evaporator 30 and a compressor 10 arranged along a first direction, specifically to... Figure 1 In the view shown, the compressor 10 is located below the evaporator 30. Understandably, when the air conditioner 100 is operating, condensation will form on the outer surface of the evaporator 30 and components such as pipes connected inside the air conditioner 100 due to temperature changes. The air conditioner 100 provided by this invention also includes a drainage device 50 for collecting and draining the condensation formed inside the air conditioner 100.

[0033] The drainage device 50 includes a first water collection tray 52 and a second water collection tray 54, with the second water collection tray 54 located below the first water collection tray 52 along a first direction. Specifically, the first water collection tray 52 is located between the evaporator 30 and the compressor 10, and the second water collection tray 54 is located on the side of the compressor 10 facing away from the second water collection tray 54. Thus, when the air conditioner 100 is operating, the condensate formed on the outer surface of the evaporator 30 can enter the first water collection tray 52 under its own gravity, and the condensate formed on the outer surface of the pipes and other components connecting the evaporator 30 and the compressor 10 inside the air conditioner 100 can enter the second water collection tray 54 under its own gravity. In this way, the first water collection tray 52 and the second water collection tray 54 comprehensively collect the condensate formed inside the air conditioner 100.

[0034] Specifically, in this embodiment, the first water collection tray 52 has a first water collection space 53, and the second water collection tray 54 has a second water collection space 55. The first water collection space 53 and the second water collection space 55 can respectively collect the condensate dripping from above them. The drainage device 50 also includes a connecting mechanism 56, which connects the first water collection tray and the second water collection tray 54 and communicates the first water collection space 53 and the second water collection space 55. The second water collection tray 54 has a drain outlet 541 that communicates with the second water collection space 55. In this way, the condensate collected in the first water collection space 53 enters the second water collection space 55 through the connecting mechanism 56, and the condensate in the first water collection space 53 gathers into the second water collection space 55. Finally, the gathered condensate flows out from the drain outlet 541 of the second water collection tray 54. Therefore, it is not necessary to set a drain outlet 541 on the first water collection pan 52, nor is it necessary to install a drain pipe on the first water collection pan 52. It is only necessary to set a drain outlet 541 on the second water collection pan 54 and install the corresponding drain pipe for the drain outlet 541. In this way, by reducing the number of drain outlets 541, the amount of drain pipe installation is reduced, and the assembly efficiency is improved.

[0035] The drain outlet 541 includes a first drain outlet 543 and a second drain outlet 545, both of which are connected to the second water accumulation space 55. The first drain outlet 543 and the second drain outlet 545 are distributed along a second direction intersecting the first direction. With the first drain outlet 543 and the second drain outlet 545 installed on the second water accumulation pan 54, condensate in the second water accumulation space 55 can be discharged from either the first drain outlet 543 or the second drain outlet 545. This allows the air conditioner 100 equipped with the drainage device 50 to be used as a marine air conditioner 100, suitable for swaying environments on the water surface.

[0036] The connecting mechanism 56 includes a first connecting component 561 and a second connecting component 563. The first connecting component 561 and the second connecting component 563 are distributed at intervals along a second direction intersecting the first direction. Both the first connecting component 561 and the second connecting component 563 are connected to the first water accumulation space 53 and the second water accumulation space 55. In this way, the first connecting component 561 at one end of the second direction connects the first water accumulation space 53 and the second water accumulation space 55, and the second connecting component 563 at the other end of the second direction also connects the first water accumulation space 53 and the second water accumulation space 55. The condensate in the first water accumulation space 53 can flow to the second water accumulation space 55 from either the first connecting component 561 or the second connecting component 563, thereby making the air conditioner 100 equipped with the cover drainage device 50 more suitable for swaying environments on water surfaces. During the oscillation process of the air conditioner 100, the condensate in the first water collection pan 52 can enter the second water collection pan 54 through the lower of the first connecting assembly 561 and the second connecting assembly 563, and then be discharged through the lower of the first drain outlet 543 and the second drain outlet 545, reliably discharging the condensate, and can be used as a marine air conditioner 100.

[0037] In some embodiments, a groove is formed on the top surface of the second water collection tray 54 facing the first water collection tray 52 to form a second water collection space 55. This groove allows condensate forming on the outer surface of the top component of the second water collection tray 54 to drip down under its own weight and eventually collect in the groove. Furthermore, both the first connecting component 561 and the second connecting component 563 have their ends facing away from the first water collection tray 52 connected to the groove, allowing condensate in the first water collection tray 52 to collect in the groove through either the first connecting component 561 or the second connecting component 563.

[0038] Furthermore, the groove extends in a direction parallel to the second direction, and the first drain outlet 543 and the second drain outlet 545 are respectively connected to the opposite ends of the groove in the second direction. In this way, the condensate collected in the groove can flow freely in the second direction and can be discharged from either the first drain outlet 543 or the second drain outlet 545.

[0039] In some embodiments, the top surface of the second water collection tray 54 includes a first guide surface 552 and a second guide surface 554. The first guide surface 552 and the second guide surface 554 are located on opposite sides of the groove along a third direction intersecting the second direction, and the first guide surface 552 and the second guide surface 554 are respectively inclined downward in the direction of approaching each other. It can be understood that the first guide surface 552 and the second guide surface 554 are arranged on opposite sides in the width direction of the groove, and both the first guide surface 552 and the second guide surface 554 are inclined downward in the direction of approaching the groove. Thus, the end of the first guide surface 552 and the second guide surface 554 that connects to the groove is relatively low, and the end of the first guide surface 552 and the second guide surface 554 that is away from the groove is relatively high. After the condensate above the second water collection tray 54 drips onto the first guide surface 552 and the second guide surface 554, it can flow into the groove under the guidance of the inclined first guide surface 552 and the second guide surface 554 to reliably collect the dripping condensate.

[0040] Optionally, the angle between the first guide surface 552 and the first direction is in the range of 84 degrees to 88 degrees, and the angle between the second guide surface 554 and the first direction is in the range of 84 degrees to 88 degrees, so as to reliably guide the condensate into the groove. Preferably, the angle between the first guide surface 552 and the first direction is 86 degrees, the angle between the second guide surface 554 and the second direction is 86 degrees, and the first guide surface 552 and the second guide surface 554 are arranged opposite each other along the first direction.

[0041] In some embodiments, both the first connecting assembly 561 and the second connecting assembly 563 include a connecting pipe 565 and a manifold 567. One end of the connecting pipe 565 is connected to the first water collection tray 52, and the manifold 567 is connected between the other end of the connecting pipe 565 and the second water collection tray 54, and the manifold 567 connects the connecting pipe 565 and the drain outlet 541. Condensate in the first water collection tray 52 enters the manifold 567 through the connecting pipe 565, and then flows to the drain outlet 541 through the manifold 567, thus guiding the condensate in the first water collection tray 52 to the drain outlet 541 for discharge through the connecting pipe 565 and the manifold 567.

[0042] Specifically, the manifold 567 is a tee pipe with interconnected first opening 571, second opening 573, and third opening 575. A connecting pipe 565 connects the first opening 571 to the first water collection tray. The second opening 573 communicates with the groove, and the third opening 575 communicates with the drain outlet 541. In this way, condensate in the first water collection tray 52 enters the tee pipe through the connecting pipe 565 from the first opening 571, condensate in the groove enters the tee pipe through the second opening 573, and finally, the condensate collected in the tee pipe flows from the third opening 575 to the drain outlet 541, thus draining the condensate. Understandably, the third opening 575 communicates with either the first drain outlet 543 or the second drain outlet 545, guiding the condensate to be discharged from either outlet. The section of the tee pipe with the third opening 575 can extend out of the second water collection tray, or the section of the tee pipe with the third opening 575 can be located within the groove; this is not limited here.

[0043] Based on the same inventive concept, the present invention also provides the aforementioned drainage device 50, which includes a first water collection tray 52 and a second water collection tray 54, with the second water collection tray 54 located below the first water collection tray 52 along a first direction. Specifically, the first water collection tray 52 is located between the evaporator 30 and the compressor 10, and the second water collection tray 54 is located on the side of the compressor 10 facing away from the second water collection tray 54. Thus, when the air conditioner 100 is operating, the condensate formed on the outer surface of the evaporator 30 can enter the first water collection tray 52 under its own gravity, and the condensate formed on the outer surface of the pipes and other components connecting the evaporator 30 and the compressor 10 inside the air conditioner 100 can enter the second water collection tray 54 under its own gravity. In this way, the first water collection tray 52 and the second water collection tray 54 comprehensively collect the condensate formed inside the air conditioner 100.

[0044] Specifically, in this embodiment, the first water collection tray 52 has a first water collection space 53, and the second water collection tray 54 has a second water collection space 55. The first water collection space 53 and the second water collection space 55 can respectively collect the condensate dripping from above them. The drainage device 50 also includes a connecting mechanism 56, which connects the first water collection tray and the second water collection tray 54 and communicates the first water collection space 53 and the second water collection space 55. The second water collection tray 54 has a drain outlet 541 that communicates with the second water collection space 55. In this way, the condensate collected in the first water collection space 53 enters the second water collection space 55 through the connecting mechanism 56, and the condensate in the first water collection space 53 gathers into the second water collection space 55. Finally, the gathered condensate flows out from the drain outlet 541 of the second water collection tray 54. Therefore, it is not necessary to set a drain outlet 541 on the first water collection pan 52, nor is it necessary to install a drain pipe on the first water collection pan 52. It is only necessary to set a drain outlet 541 on the second water collection pan 54 and install the corresponding drain pipe for the drain outlet 541. In this way, by reducing the number of drain outlets 541, the amount of drain pipe installation is reduced, and the assembly efficiency is improved.

[0045] The drain outlet 541 includes a first drain outlet 543 and a second drain outlet 545, both of which are connected to the second water accumulation space 55. The first drain outlet 543 and the second drain outlet 545 are distributed along a second direction intersecting the first direction. With the first drain outlet 543 and the second drain outlet 545 installed on the second water accumulation pan 54, condensate in the second water accumulation space 55 can be discharged from either the first drain outlet 543 or the second drain outlet 545. This allows the air conditioner 100 equipped with the drainage device 50 to be used as a marine air conditioner 100, suitable for swaying environments on the water surface.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
