[0002] In the current air conditioning industry, most air conditioners' evaporators are placed directly on the water pan. When the air conditioner encounters a high humidity environment and the fan speed is high, the air conditioner will blow water. In addition, because the fins are in contact with the water pan, when the air conditioner equipment is shut down, the condensed water between the fins and the water pan cannot be discharged due to the tension of the water itself. The stagnant water that does not flow for a long time is prone to breed bacterial sticky substances, thereby blocking the drain port and affecting the drainage of the air conditioner during subsequent operation.

DETAILED DESCRIPTION
[0031] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0032] like Figures 1 to 8 As shown, the utility model provides an air-conditioning evaporator drainage structure and an air-conditioner, which are used to solve the water blowing problem that occurs when the fan speed is high and the problem that the drainage of evaporator condensed water is not clean, resulting in poor drainage of generated bacterial viscous matter.
[0033] like Figures 1 to 8 As shown, in one embodiment, the drainage structure includes a water collection tray 5, and a water collection tray drain port 51 is provided at one end of the bottom of the water collection tray 5. The water collection tray drain port 51 is also located on the side where the fan 2 turns. Furthermore, the blades of the fan 2 rotate clockwise, and an angle is formed between one side wall of the water collection tray 5 and the bottom of the water collection tray 5 to form a slope 52. The water collection tray drain port 51 protrudes from the bottom of the water collection tray 5 to form a drainage bag 53, so that drainage is smoother.
[0034] like Figures 1 to 4 and Figure 6 to Figure 7 As shown, in one embodiment, the drainage structure includes a drainage groove 6, and the drainage groove 6 is arranged in the water collection tray 5. The bottom of the drainage groove 6 is in contact with the bottom of the water collection tray 5. Furthermore, the bottom of the drainage groove 6 and the bottom of the water collection tray 5 can also be fixed together. A drainage groove outlet 61 is provided on one side of the drainage groove 6 close to the drainage port 51 of the water collection tray.
[0035] The height of the bottom of the water collection tray 5 and the drainage groove 6 on the side close to the water collection tray drain outlet 51 is smaller than the height of the bottom of the water collection tray 5 and the drainage groove 6 on the side away from the water collection tray drain outlet 51. The height difference and the slope 52 are used to allow the condensed water to flow smoothly to the water collection tray drain outlet 51 for discharge.
[0036] like Figures 1 to 3 and Figure 6 to Figure 7 As shown, in one embodiment, the drainage structure includes an evaporator component 4, and fixing plates 44 are provided on both sides of the evaporator component 4. The bottom of the fixing plate 44 is fixed to the drainage groove 6, and a drainage space 62 is formed between the bottom of the evaporator component 4 and the drainage groove 6. The bottom surface of the evaporator component 4 is located in the drainage groove 6. The evaporator component 4 includes a fin 41 and a refrigerant tube 43. The fin 41 has a cavity inside, and the refrigerant tube 43 is provided in the cavity. A plurality of through holes 42 are opened on both sides of the fin 41, and the refrigerant tube 43 has a rotating U-shaped structure. Both ends of the refrigerant tube 43 pass through the fin 41 through the through holes 42, and then pass through the fin 41 through the through holes 42, forming a plurality of curved semicircular pipes on both sides of the fin 41.
[0037] like Figures 3 to 7 As shown, the drainage groove 6 covers the bottom surface of the evaporator assembly 4 and the evaporator assembly 4 and the drainage groove 6 are not in contact, and most of the condensed water generated by the evaporator assembly 4 during heat exchange drips into the drainage space 62 of the drainage groove 6, and then flows into the water collection pan drainage port 51 through the drainage groove outlet 61 for discharge, while the condensed water generated by the multiple curved semicircular pipes on both sides of the evaporator assembly 4 located outside the cavity of the fin 41 directly drips onto the water collection pan 5, and then flows into the water collection pan drainage port 51 for discharge due to the height difference.
[0038] like Figure 8 As shown, the drainage groove 6 wraps the fin 41 and the fin 41 and the drainage groove 6 are not in contact, that is, there is a certain distance between the fin 41 and the drainage groove 6. The distance between the fin 41 and the drainage groove 6 cannot be too large to prevent the condensed water in the drainage groove 6 from being blown out.
[0039] like Figure 3 and Figure 7 As shown, the length and width of the evaporator assembly 4 and the drainage groove 6 are smaller than the length and width of the water collection tray 5. Specifically, both ends of the evaporator assembly 4 and the drainage groove 6 do not exceed the water collection tray 5, so that the generated condensed water can be discharged through the water collection tray 5.
[0040] like Figures 1 to 7 The utility model further provides an air conditioner, which includes the drainage structure as described above.
[0041] like Figure 1 As shown, in one embodiment, the air conditioner further includes an air conditioning housing 1, the air conditioning housing 1 has a receiving cavity inside, and the drainage structure is fixed in the receiving cavity.
[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the air conditioner further includes a middle partition plate 3 , which is disposed in the accommodating cavity and is fixedly connected to the air conditioning housing 1 .
[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the air conditioner further comprises a fan 2, the fan 2 is located in the accommodating cavity, one end of the fan 2 is fixedly connected to the middle partition 3, and the fan 2 is located above the drainage structure. The air conditioner further comprises a front cover plate (not shown in the figure), and the front cover plate can cover the accommodating cavity.
[0044] like Figure 1 and Figure 2 As shown, one side of the water collection tray 5 is fixedly connected to one end of the middle partition plate 3 .
[0045] Principle of the utility model:
[0046] During operation, the fan 2 inhales hot air and then absorbs heat through the evaporator assembly 4 and blows out cold air for cooling. The drainage groove 6 is fixedly connected to the evaporator assembly 4, and most of the condensed water produced by the evaporator assembly 4 drips into the drainage groove 6 and is then discharged from the drainage groove outlet 7. The remaining small part of the condensed water produced by the semicircular pipes on both sides of the evaporator assembly 4 drips directly onto the water accumulation tray and is discharged through the water accumulation tray 5.
[0047] Since most of the condensed water is in the drainage groove 6, there will be no water blowing phenomenon due to excessive condensed water when the fan 2 rotates at a high speed. Secondly, since the fins 41 of the evaporator assembly 4 can be achieved without contacting other structural parts in the air conditioner, the condensed water can be smoothly dripped into the drainage groove 6 under the action of gravity and discharged from the drainage groove water outlet 7, which solves the problem that the condensed water between the fins 41 and the structural parts cannot be smoothly discharged due to the tension of water after the fins 41 come into contact with other structural parts. Finally, due to the height difference between the water accumulation tray 5 and the bottom of the drainage groove 6, the accumulated water can be discharged when the air-conditioning equipment is stopped after cooling, so that the air-conditioning duct can be kept dry for a long time, and the residual condensed water and bacteria between the fins 41 and the other structural parts will not generate viscous substances that affect the drainage during the subsequent operation of the air conditioner.
