[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 12 As shown, an embodiment of the present invention provides an air conditioner, comprising: a first component 10; a second component 20; an upper water receiving tray 30, which is arranged below the first component 10 to at least receive condensed water on the first component 10, and the upper water receiving tray 30 has an upper drain port 31; a lower water receiving tray 40, which is arranged below the upper water receiving tray 30 and the second component 20 to at least receive condensed water on the second component 20 and condensed water discharged from the upper drain port 31, and the lower water receiving tray 40 has a lower drain port 41.

[0035] With this solution, the upper water tray 30 and the lower water tray 40 can collect condensed water dripping from different components. The condensed water collected by the upper water tray 30 can be discharged to the lower water tray 40 through the upper drain port 31, and then the condensed water collected by the lower water tray 40 is uniformly discharged through the lower drain port 41. In this way, only one drainage pipeline needs to be set up to connect with the lower drain port 41, and no auxiliary drainage pipeline is required. Therefore, this solution can reduce pipeline connections and avoid the problem of pipeline falling off, thereby ensuring the discharge of condensed water and improving the safety of the air conditioner.

[0036] In this embodiment, the upper water receiving tray 30 includes an upper body and an upper drain pipe 32 arranged below the upper body, the upper body has an upper drain port 31, and the upper drain pipe 32 is connected to the upper drain port 31; the lower water receiving tray 40 has a water receiving slope 42 inclined relative to the horizontal plane, the lower end of the water receiving slope 42 extends to the lower drain port 41, and the lower end of the upper drain pipe 32 faces the water receiving slope 42. The upper drain pipe 32 is used to discharge the condensed water collected by the upper body. By setting the water receiving slope 42, the condensed water discharged from the upper drain pipe 32 can be guided to facilitate the condensed water to enter the lower drain port 41. Among them, the inclination angle of the water receiving slope 42 relative to the horizontal plane is about 70°.

[0037] In this embodiment, the side wall of the upper water receiving tray 30 has an overflow port 33, and the condensed water overflowing from the overflow port 33 flows into the lower water receiving tray 40. When there is more water in the upper water receiving tray 30, or the upper drain port 31 is blocked, the condensed water can flow from the overflow port 33 into the lower water receiving tray 40, thus ensuring that the condensed water in the upper water receiving tray 30 flows smoothly into the lower water receiving tray 40, preventing the condensed water in the upper water receiving tray 30 from flowing randomly, and improving reliability.

[0038] In this embodiment, the upper water receiving tray 30 includes an upper body, which includes an upper bottom wall 34, an upper side enclosure 35 and two guide ribs 36. The upper side enclosure 35 surrounds the periphery of the upper bottom wall 34, the overflow port 33 is located at the upper side enclosure 35, and the two guide ribs 36 are arranged at intervals on the upper side enclosure 35. The overflow port 33 is located between the two guide ribs 36. The upper surface of the overflow port 33 is lower than the upper surface of the upper side enclosure 35. The two guide ribs 36 can guide the condensed water flowing out of the overflow port 33.

[0039] Optionally, the upper body further includes a guide plate, which is connected to the bottom surface of the upper side enclosure 35, and is located between the two guide ribs 36. The guide plate is a tapered structure that is wide at the top and narrow at the bottom. The guide plate can guide the water flowing out of the overflow port 33, reduce surface tension, and facilitate the flow of water.

[0040] In this embodiment, the upper water receiving tray 30 includes an upper body, the upper body includes an upper bottom wall 34, the upper drain port 31 is located on the upper bottom wall 34, the upper bottom wall 34 has a first upper drain surface 37 and a second upper drain surface 38 arranged obliquely relative to the horizontal plane, and the lower ends of the first upper drain surface 37 and the second upper drain surface 38 both extend to the upper drain port 31. Through the above arrangement, the condensed water falling on the first upper drain surface 37 and the second upper drain surface 38 can be collected to the upper drain port 31 for centralized discharge. Among them, the inclination angle of the first upper drain surface 37 and the second upper drain surface 38 relative to the horizontal plane is set to 1-3°.

[0041] In this embodiment, the lower water receiving tray 40 includes a first water receiving portion 43 and a second water receiving portion 44, the first water receiving portion 43 has a first water receiving groove, the side wall of the first water receiving groove has a water flow port 431, the second water receiving portion 44 has a second water receiving groove, the second water receiving groove is lower than the first water receiving groove, the water flowing out of the water flow port 431 enters the second water receiving groove, and the lower drain port 41 is located in the second water receiving groove. The first water receiving groove and the second water receiving groove are used to receive condensed water generated by different components. The different heights of the first water receiving portion 43 and the second water receiving portion 44 facilitate arrangement in a limited space, making the air conditioner structure compact.

[0042] In this embodiment, the bottom wall of the first water receiving trough has a first lower drainage surface 432 and a second lower drainage surface 433 which are arranged obliquely relative to the horizontal plane, and the lower ends of the first lower drainage surface 432 and the second lower drainage surface 433 both extend to the water flow port 431. This can improve the flow effect of the condensed water and facilitate the condensed water to be collected at the water flow port 431.

[0043] In this embodiment, the bottom wall of the second water receiving trough has a third lower drainage surface 441 and a fourth lower drainage surface 442 which are arranged to be inclined relative to the horizontal plane, and the lower ends of the third lower drainage surface 441 and the fourth lower drainage surface 442 both extend to the lower drainage port 41. The flow effect of condensed water can be improved through the third lower drainage surface 441 and the fourth lower drainage surface 442, so that the condensed water can be easily collected at the lower drainage port 41. Among them, the inclination angle of the third lower drainage surface 441 and the fourth lower drainage surface 442 relative to the horizontal plane can be set to be more than 5°.

[0044] In this embodiment, the lower drain port 41 has a tapered surface 45, and the lower water receiving tray 40 has a first anti-blocking groove 46. The first anti-blocking groove 46 is recessed from the tapered surface 45 to the solid part of the lower water receiving tray 40. Through the above arrangement, the lower drain port 41 can be prevented from being blocked. Specifically, Figures 9 to 12As shown, when a relatively large foreign object stays at the position of the lower drain port 41, the foreign object contacts the conical surface 45. Since the first anti-blocking groove 46 is recessed from the conical surface 45 to the solid part of the lower water receiving tray 40, there is a gap between the first anti-blocking groove 46 and the foreign object, that is, the first anti-blocking groove 46 will not be blocked, so that condensed water can flow into the lower drain port 41 through the gap between the first anti-blocking groove 46 and the foreign object and be discharged. Therefore, this solution improves the reliability of the lower water receiving tray 40.

[0045] Furthermore, the first anti-blocking groove 46 is arranged obliquely relative to the horizontal plane, the lower drain port 41 and the first anti-blocking groove 46 are both located on the bottom wall of the lower water receiving tray 40, and the bottom wall of the lower water receiving tray 40 is also provided with a second anti-blocking groove 47, which is connected to the upper end of the first anti-blocking groove 46. The second anti-blocking groove 47 is lower than the upper surface of the bottom wall. Condensed water can be collected and flow into the first anti-blocking groove 46 through the second anti-blocking groove 47, so that when there is foreign matter in the lower drain port 41, the condensed water can still be guaranteed to flow out.

[0046] In this embodiment, the lower water tray 40 includes a lower body and a lower drain pipe 48 disposed below the lower body, the lower body has a lower drain port 41, the lower drain pipe 48 is connected to the lower drain port 41, and the air conditioner further includes a drainage pipe 50, the drainage pipe 50 is connected to the lower drain pipe 48. The water discharged from the lower drain pipe 48 is discharged through the drainage pipe 50, for example, to the outside. Only one drainage pipe 50 needs to be provided to connect to the lower drain port 41, and no auxiliary drainage pipeline is required. Therefore, this solution can reduce pipeline connections and avoid the problem of pipeline falling off, thereby ensuring the discharge of condensed water and improving the safety of the air conditioner.

[0047] Furthermore, the first component 10 is a heat exchanger, the second component 20 is an air duct component, and the air conditioner further includes: a refrigerant pipe 60, the refrigerant pipe 60 is connected to the heat exchanger; a sealing bowl 70, which is used to receive condensed water on the refrigerant pipe 60, the refrigerant pipe 60 passes through the sealing bowl 70, the sealing bowl 70 and the refrigerant pipe 60 are sealed and matched, the sealing bowl 70 is located above the upper water receiving tray 30, and the drainage port of the sealing bowl 70 faces the upper water receiving tray 30 to discharge the condensed water to the upper water receiving tray 30. In this way, the sealing bowl 70 can receive the condensed water on the refrigerant pipe 60 and discharge the condensed water to the upper water receiving tray 30, and then be discharged uniformly by the lower water receiving tray 40. In this way, the condensed water can be further collected and the setting of additional water diversion pipelines can be avoided.

[0048] This solution provides a drainage structure, which, through reasonable arrangement of the structure and characteristic design of internal structural parts, satisfies the purpose of using a single drainage pipe to drain the condensed water inside the air conditioner, thereby eliminating the setting of the auxiliary drainage pipe, improving safety while improving production efficiency and reducing costs. Through the reasonable arrangement of the water connection structure, a single drainage pipe is used to drain the internal condensed water, effectively avoiding the risk of safety hazards caused by the drainage pipe falling off in the air conditioner.

[0049] This layout can meet the layout integrity of the air conditioner's drainage structure, and the rationality of the entire drainage structure also correspondingly improves the safety of the air conditioner's operation. At the same time, since the drainage structure mentioned in this solution only involves one drainage pipe, the problem of the auxiliary drainage pipe mentioned in the background easily falling off is avoided from the root, and safety and reliability are further guaranteed.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
