[0031] Example 1, such as Figures 1-4As shown, a parking air conditioner with a condensate drainage structure includes an outer shell 1, a side shell panel 3, and an inner panel 6. The outer shell 1 and the inner panel 6 are assembled by fastening and secured with bolts. The side shell panel 3 is fixed to one side of the inner wall of the outer shell 1 and adjacent to one side of the inner panel 6. The surface of the side shell panel 3 is provided with a drainage slope 31 and a water-blocking rib 32. The water-blocking rib 32 is adjacent to one side of the drainage slope 31. A compressor 5 and an exhaust fan 4 are also provided on one side of the side shell panel 3. The exhaust fan 4 consists of a motor that drives the fan blades to rotate, fan blades, and a filter screen. The filter screen side of the exhaust fan 4 protrudes from the inner wall of the outer shell 1 and is located on the outer side of the outer shell 1. A control box 7 is installed on one side of the inner panel 6. The surface of the control box 7 is provided with control buttons for controlling the parking air conditioner and an air duct 8 for air outlet. A protective device 2 is installed near the exhaust fan 4 on the surface. When the parking air conditioner produces cold air, the compressor 5 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant gas enters the condenser and releases heat to the outside through heat dissipation. The refrigerant is cooled into a high-pressure liquid. The high-pressure liquid refrigerant enters the evaporator through the expansion valve. During the evaporation process, it absorbs a large amount of heat, which cools the air. The cooled air is then blown into the vehicle through the fan at the air duct 8 to achieve a cooling effect. The condensate produced during cooling flows through the surface of the drainage slope 31 at the side plate 3 of the shell to the outside of the shell 1 and is discharged. The water-blocking ribs 32 can block the flow of condensate. When heating, the air is directly heated by the PTC heater and then blown into the vehicle through the air duct 8.

[0032] Reference Figures 1-6 As shown in this embodiment: the protective device 2 includes a frame rod 21 and a rotating rod 23. The frame rod 21 is fixed to the outside of the housing 1. A servo motor 22 is installed at the top of the frame rod 21. The servo motor 22 is used to drive the rotating rod 23 to rotate. A baffle 24 is installed on one side of the rotating rod 23. The two sides of the baffle 24 are fixedly connected to one side of the rotating rod 23 and one side of the frame rod 21, respectively. By setting the baffle 24, when the parking air conditioner is not in use, the servo motor 22 can be operated to drive the rotating rod 23 to rotate, so that the rotating rod 23 rotates towards the side of the frame rod 21 that is not connected to the baffle 24. When the outer surface of the rotating rod 23 contacts the surface of the support rod 21 at the other end, the baffle 24 will unfold, so that the baffle 24 is fan-shaped and positioned above the exhaust fan 4, blocking and protecting the top of the exhaust fan 4, minimizing the amount of dust entering the exhaust fan 4, thereby reducing the frequency of cleaning the exhaust fan 4. When the parking air conditioner is working, the servo motor 22 drives the rotating rod 23 to rotate towards the support rod 21 with the baffle 24, so that the rotating rod 23 is parallel to the support rod 21 with the baffle 24, and the baffle 24 is folded and retracted between the support rod 21 and the baffle 24.

[0033] Reference Figures 5-6As shown in this embodiment: the baffle 24 is made of TPU composite fabric. By making the baffle 24 of TPU composite fabric, rainwater is less likely to penetrate the baffle 24 and cause it to stick to mud and dust in rainy weather. A baffle 25 is fixedly connected to one side of the top of the frame 21. The baffle 25 is located above the side of the frame 21 where the baffle 24 is set. The outer surface of the baffle 25 is arc-shaped. By setting the baffle 25, the top of the frame 21 can be protected, and hard debris such as branches can be prevented from entering between the frame 21 and the rotating rod 23 when the baffle 24 is unfolded, thus affecting the folding of the baffle 24. A conical push rod 26 is fixedly connected to one side of the rotating rod 23. The end of the push rod 26 away from the rotating rod 23 is narrow. By setting the push rod 26, when the rotating rod 23 is rotated and the baffle 24 is unfolded, it can push the branches, leaves and other debris on the surface of the exhaust fan 4 filter screen away from the surface of the exhaust fan 4, thus preventing debris from getting stuck in the exhaust fan 4 filter screen and affecting the exhaust effect of the exhaust fan 4.

[0034] Reference Figures 5-7 As shown in this embodiment: a positioning component 27 is provided on one side of the outer casing 1. The positioning component 27 includes a groove rod 272, a sliding rod 273, a connecting rod 275, and a pressure block 277. The groove rod 272 is fixed to the top of the outer casing 1. A round rod 276 is fixedly connected to the top of the pressure block 277. The sliding rod 273 slides on the inner wall of the groove rod 272 and is connected to the round rod 276 and the pressure block 277 via the connecting rod 275. A spring 274 is provided inside the groove rod 272 to limit the position of the sliding rod 273. The spring 274 is located below the sliding rod 273 and at the top of the rotating rod 23. Two inclined slots 271 are provided. When the servo motor 22 drives the rotating rod 23 to rotate and unfold the baffle 24, the inclined slot 271 at the top of the rotating rod 23 contacts the bottom end of the pressure block 277, which pushes the round rod 276 and the connecting rod 275 to make the sliding rod 273 slide upward on the inner wall of the slot rod 272 and stretch the spring 274. After the rotating rod 23 moves away from the pressure block 277, the spring 274 returns to its original state and pulls the sliding rod 273 downward to press the pressure block 277 onto the surface of the baffle 24, so that the outer side of the baffle 24 can fit as closely as possible to the surface of the outer shell 1, thereby improving the dustproof effect of the baffle 24.

[0035] Reference Figures 5-7 As shown in this embodiment: a support rod 278 is fixedly connected to the bottom end of the connecting rod 275. The end of the support rod 278 away from the connecting rod 275 is fixedly connected to one side of the round rod 276. By setting the support rod 278, the connection between the connecting rod 275 and the round rod 276 can be strengthened, and the structural strength of the outer surface of the connecting rod 275, the round rod 276 and the pressure block 277 can be improved. The bottom end of the pressure block 277 is a smooth outer surface and is arc-shaped. By setting the bottom end of the pressure block 277 to be an arc-shaped smooth surface, the pressure block 277 will not press down on the barrier cloth 24 and affect the movement of the barrier cloth 24 when the bottom end of the pressure block 277 moves.

[0036] Working principle: When the parking air conditioner is working, the servo motor 22 drives the rotating rod 23 to rotate towards the support rod 21 with the baffle 24, making the rotating rod 23 parallel to the support rod 21 with the baffle 24. The baffle 24 is retracted and folded between the support rod 21 and the baffle 24. When cold air is generated, the compressor 5 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas. The high-temperature, high-pressure refrigerant gas enters the condenser, where it releases heat to the outside through heat dissipation, cooling the refrigerant into a high-pressure liquid. The high-pressure liquid refrigerant enters the evaporator through the expansion valve, absorbing a large amount of heat during evaporation, thus cooling the air. The cooled air is then blown into the vehicle through the fan at the air duct 8, achieving a cooling effect. The condensate produced during cooling flows through the drainage slope 31 at the side plate 3 of the shell to the outside of the shell 1 for discharge. The water-blocking ribs 32 can block the flow of condensate. During heating, the air is directly heated by the PTC heater and then... When the air duct 8 blows into the vehicle, and the parking air conditioner is not in use, the servo motor 22 can be operated to drive the rotating rod 23 to rotate, causing the rotating rod 23 to rotate towards the side of the support rod 21 that is not connected to the baffle 24. When the outer surface of the rotating rod 23 contacts the surface of the support rod 21 at the other end, the baffle 24 will be unfolded, so that the baffle 24 is fan-shaped and located above the exhaust fan 4, blocking and protecting the top of the exhaust fan 4. At the same time, when the rotating rod 23 rotates and unfolds the baffle 24, when the inclined groove 271 at the top of the rotating rod 23 contacts the bottom end of the pressure block 277, it will push the round rod 276 and the connecting rod 275, causing the sliding rod 273 to slide upward on the inner wall of the groove rod 272 and stretch the spring 274. After the rotating rod 23 moves away from the pressure block 277, the spring 274 returns to its original state and pulls the sliding rod 273 downward to press the pressure block 277 onto the surface of the baffle 24, so that the outer side of the baffle 24 can fit as closely as possible to the surface of the outer shell 1, minimizing the amount of dust entering the exhaust fan 4.
