It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0025] like Figure 1 and Figure 2 As shown, in one aspect, this application provides a drainage device 1, which includes a water receiving tray 10, a drain pipe 20, a first drain pump 31 and a first vibrator 32. It can eliminate the blockage of the drain pipe 20 when the demand for condensate drainage is large, ensuring that the condensate can be quickly discharged from the air conditioner, thereby ensuring the safety of the components inside the air conditioner.

[0026] The drip tray 10 is used to collect condensate. When the drainage device 1 is applied to an air conditioner, the drip tray 10 can be installed below the outdoor / indoor heat exchanger to collect condensate generated by the outdoor / indoor heat exchanger. The drip tray 10 has a drain outlet 11, and the drain pipe 20 is connected to the drain outlet 11. The first drain pump 31 is installed on the drain pipe 20 and can be started or stopped as needed. When started, it draws the water accumulated in the drip tray 10 into the drain pipe 20 through the drain outlet 11 and discharges the water in the drain pipe 20 to the outside of the air conditioner, thus achieving an auxiliary drainage function. The first vibrator 32 is installed on the side wall of the drain pipe 20 to vibrate and eliminate blockages in the drain pipe 20.

[0027] Compared with related technologies, the drainage device 1 provided in this application embodiment is equipped with a first vibrator 32. When there is a risk of blockage in the drainage pipe 20, the first vibrator 32 can vibrate. The vibration is transmitted to the inside of the drainage pipe 20 through the side wall of the drainage pipe 20, causing the water in the drainage pipe 20 to vibrate and resume rapid flow, thereby eliminating the risk of blockage in the drainage pipe 20, ensuring that the condensate can be quickly discharged from the air conditioner when the drainage demand is large, preventing the condensate from damming in the water receiving pan 10 and ensuring the safety of the components inside the air conditioner.

[0028] In some embodiments, the drainage device 1 may further include a tracer storage unit 41 and a first tracer color sensor 42. The water receiving tray 10 is provided with a tracer injection port 12 communicating with the drain outlet 11, and the release end of the tracer storage unit 41 is connected to the tracer injection port 12. The tracer storage unit 41 stores tracer, which can be released into the condensate collected in the water receiving tray 10 as needed. The first tracer color sensor 42 is disposed on the drain pipe 20 and is used to identify the color of the water in the drain pipe 20. When the first tracer color sensor 42 identifies a color in the water in the drain pipe 20 that matches the tracer, it can be determined that the drain pipe 20 is in a normal drainage state and that the drain pipe 20 is not clogged; when the first tracer color sensor 42 does not identify a color in the water in the drain pipe 20 that matches the tracer, it can be determined that the drain pipe 20 is clogged, and the first vibrator 32 can be controlled to vibrate to eliminate the clog in the drain pipe 20. By setting up a tracer storage device 41 and a first tracer color sensor 42, it is possible to determine more accurately whether the drain pipe 20 is clogged, so that the clog can be eliminated in time when it occurs, ensuring that the condensate can be discharged quickly.

[0029] In some examples, the drainage device 1 may further include a first tracer circulation pipe 43 and a tracer circulation pump 44, with the tracer circulation pump 44 disposed on the first tracer circulation pipe 43. A tracer circulation port 13 may be provided on the water receiving tray 10, positioned between the tracer inlet 12 and the drain outlet 11, such that the tracer inlet 12, tracer circulation port 13, and drain outlet 11 are arranged sequentially from top to bottom. A first tracer return port 21 may be provided on the side wall of the drain pipe 20, and the first tracer circulation pipe 43 connects the first tracer return port 21 and the tracer circulation port 13. Thus, the tracer circulation pump 44 can drive a portion of the water flow along the first tracer circulation pipe 43 to circulate between the water receiving tray 10 and the drain pipe 20, carrying at least a portion of the tracer in the same flow, thereby improving the tracer recycling rate.

[0030] In some embodiments, the drainage device 1 may further include a first flow velocity sensor 33, which is used to detect the drainage speed of the drainage pipe 20. Here, the first flow velocity sensor 33 can detect the flow velocity of the water in the drainage pipe 20, thereby detecting the drainage speed of the drainage pipe 20. Based on the detection value of the first flow velocity sensor 33, the drainage volume of the drainage pipe 20 and whether blockage has occurred can be determined, and corresponding response actions can be taken. When the detection value of the first flow velocity sensor 33 is greater than or equal to a first preset value, it indicates that the drainage volume of the drainage pipe 20 is large, and the first drainage pump 31 can be started for auxiliary drainage; when the detection value of the first flow velocity sensor 33 is less than the first preset value but greater than zero, it indicates that the drainage volume of the drainage pipe 20 is small, and the first drainage pump 31 can not be started for auxiliary drainage; and when the detection value of the first flow velocity sensor 33 is equal to zero, it indicates that the drainage pipe 20 is blocked, and the first vibrator 32 can be controlled to vibrate to eliminate the blockage of the drainage pipe 20.

[0031] In some embodiments, the drip tray 10 may also be provided with an overflow port 14, which is located above the drain outlet 11. The drainage device 1 may also include an overflow pipe 50 and a second vibrator 62, with the overflow pipe 50 connected to the overflow port 14. The second vibrator 62 is disposed on the outer wall of the overflow pipe 50 and is used to vibrately eliminate blockages in the drain pipe 20. When the water level in the drip tray 10 reaches above the height of the overflow port 14, the water in the drip tray 10 can overflow from the overflow port 14 to increase the drainage volume and speed of condensate and prevent condensate from damming in the drip tray 10. When there is a risk of blockage in the overflow pipe 50, the second vibrator 62 can vibrate, and the vibration is transmitted through the side wall of the overflow pipe 50 to the interior of the overflow pipe 50, causing the water in the overflow pipe 50 to vibrate and resume rapid flow, thereby eliminating the risk of blockage in the overflow pipe 50.

[0032] In some examples, the water receiving tray 10 may also be provided with a tracer injection port 12, and the overflow port 14, tracer injection port 12, and drain port 11 are arranged sequentially from top to bottom. The drainage device 1 may also include a tracer storage unit 41 and a second tracer color sensor 45, with the release end of the tracer storage unit 41 connected to the tracer injection port 12. The second tracer color sensor 45 is disposed on the overflow pipe 50 and is used to identify the color of the water in the overflow pipe 50. When the second tracer color sensor 45 identifies the same color as the tracer in the water in the overflow pipe 50, it can be determined that the overflow pipe 50 is in a normal drainage state and the overflow pipe 50 is not blocked; when the second tracer color sensor 45 does not identify the same color as the tracer in the water in the overflow pipe 50, it can be determined that the overflow pipe 50 is blocked, and then the second vibrator 62 can be controlled to vibrate to eliminate the blockage of the overflow pipe 50. By setting up a tracer storage device 41 and a second tracer color sensor 45, it is possible to determine more accurately whether the overflow pipe 50 is blocked, so that the blockage can be eliminated in time and the condensate can be discharged quickly.

[0033] For example, the drainage device 1 may further include a second tracer circulation pipe 46 and a tracer circulation pump 44, the tracer circulation pump 44 being disposed on the second tracer circulation pipe 46. A tracer circulation port 13 may be provided on the water receiving tray 10, and the tracer circulation port 13 may be disposed between the tracer injection port 12 and the drain port 11. A second tracer return port 51 may be provided on the side wall of the overflow pipe 50, and the second tracer circulation pipe 46 connects the second tracer return port 51 and the tracer circulation port 13. In this way, the tracer circulation pump 44 can drive a portion of the water flow to circulate along the second tracer circulation pipe 46 between the water receiving tray 10 and the overflow pipe 50, and this portion of the water flow carries at least a portion of the tracer to circulate between the water receiving tray 10 and the overflow pipe 50, improving the tracer recycling rate.

[0034] In some examples, the drainage device 1 may also include a second drainage pump 61, which is disposed on the overflow pipe 50. The second drainage pump 61 can be started as needed to draw water accumulated in the water receiving pan 10 into the overflow pipe 50 through the overflow port 14 and cause the water in the overflow pipe 50 to be discharged outside the air conditioner, thereby achieving an auxiliary drainage function.

[0035] In some examples, the drainage device 1 may also include a second flow rate sensor 63, which is used to detect the drainage speed of the overflow pipe 50. Here, the second flow rate sensor 63 can detect the flow rate of water in the overflow pipe 50, thereby detecting the drainage speed of the overflow pipe 50. Based on the detection value of the second flow rate sensor 63, the drainage volume of the overflow pipe 50 and whether blockage has occurred can be determined, and corresponding response actions can be taken. When the detection value of the second flow rate sensor 63 is greater than or equal to a second preset value, it indicates that the drainage volume of the overflow pipe 50 is large, and the second drainage pump 61 can be started for auxiliary drainage; when the detection value of the second flow rate sensor 63 is less than the second preset value but greater than zero, it indicates that the drainage volume of the overflow pipe 50 is small, and the second drainage pump 61 can not be started for auxiliary drainage; and when the detection value of the second flow rate sensor 63 is equal to zero, it indicates that the overflow pipe 50 is blocked, and the second vibrator 62 can be controlled to vibrate to eliminate the blockage of the overflow pipe 50.

[0036] On the other hand, this application provides an air conditioner that includes the drainage device 1 provided in any of the above embodiments. The type of air conditioner can be determined according to actual needs, and may include, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted unit, or an in-row air conditioner. This application does not limit this type. The air conditioner provided in this application, with the aforementioned drainage device 1, can eliminate blockages in the drain pipes 20 when the demand for condensate drainage is large, ensuring that condensate can be quickly discharged from the air conditioner, thereby ensuring the safety of the components inside the air conditioner.
