In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Figures 1 to 4 The above-mentioned device is a device for collecting and discharging condensed water from an overhead tour bus air conditioner, comprising a water collecting box 1 with a water collecting chamber 12 provided therein. The water collecting box 1 is a rectangular parallelepiped structure, and its capacity size can be designed according to the estimated amount of air conditioning condensed water. The top of the water collecting box 1 is provided with an opening connected to the water collecting chamber 12 up and down, and a top plate connecting plate 2 is fixedly provided at the opening. A vertical upward drainage pipe 21 is fixedly provided on the connecting plate 2. The lower end of the drainage pipe 21 passes through the top plate connecting plate 2 and is connected to the water collecting chamber 12. The size of the drainage pipe 21 can be selected according to the estimated flow rate of air conditioning condensed water, and its top is connected to the condenser water pan 64 located in the air conditioning evaporation unit 61 in the air conditioning unit 6. The evaporator 1 in the air conditioning unit 6 The air-conditioning condensate collected by the condenser water pan 64 below 3 flows into the water collecting box 1 through the drainage pipe 21; a side drain pipe 3 is fixedly provided at a position near the bottom on the right side of the water collecting box 1, one end of the side drain pipe 3 passes through the water collecting box 1 and is communicated with the water collecting chamber 12, and a solenoid valve 31 is provided on the side drain pipe 3 at a position outside the water collecting box 1, and the other end of the side drain pipe 3 is bent downward at a 90° right angle relative to the other end located in the water collecting chamber 12, and the solenoid valve 31 is controlled by the air-conditioning controller arranged in the air-conditioning unit 6, and the air-conditioning controller realizes signal control through the vehicle network. The vehicle network can send arrival and departure signals to the air-conditioning controller, and the opening and closing of the solenoid valve 31 is controlled by the air-conditioning controller.

[0025] In order to prevent the solenoid valve 31 from being unable to drain water when it fails or to perform manual drainage when necessary, a lower drain pipe 41 is fixedly provided at the bottom of the water collecting box 1. One end of the lower drain pipe 41 passes through the water collecting box 1 and is connected to the water collecting chamber 12, and the other end is bent 90° and extends to the left side of the water collecting box 1; a drain valve 4 is provided on the lower drain pipe 41 extending to the left side of the water collecting box 1. The drain valve 4 is a manual drain valve, which is provided on the outside of the air-conditioning unit 6 for easy adjustment. Manual drainage operation can be achieved through the manual drain valve, so that the vehicle can continue to run, further improving reliability.

[0026] In order to balance the air pressure inside and outside the water collecting box 1 and enable the water collecting box 1 to collect as much air-conditioning condensed water as possible, a through hole communicating with each other from top to bottom is provided on the top plate connecting plate 2, and an exhaust hole valve 5 is fixedly provided on the through hole.

[0027] In order to facilitate the installation and disassembly of the water collecting box 1 and the air-conditioning unit 6, the upper and lower ends of the water collecting box 1 are respectively provided with a flange joint 11 bent at a 90° right angle near the left side. The two groups of flange joints 11 at the upper and lower ends are symmetrical up and down. The flange joint 11 is provided with fixing holes connected to the left and right. Bolts that can avoid fixed connection with the air-conditioning unit 6 are passed through the fixing holes. The stability and reliability of the connection between the water collecting box 1 and the wall of the air-conditioning unit 6 are ensured by bolt connection, which is conducive to disassembly and convenient for the later maintenance of the water collecting box 1 and its parts.

[0028] In order to facilitate taking out the water collecting box 1 , an operating handle is fixedly provided on the right side of the water collecting box 1 above the side drain pipe 3 .

[0029] In order to facilitate the disassembly of the water collecting box 1 and to facilitate the inspection of the water collecting cavity 12 of the water collecting box 1, the top plate connecting plate 2 and the water collecting box 1 are fixedly connected by bolts or riveted to form a tight fit.

[0030] like Figure 5As shown, the water collecting box 1 is located in the air-conditioning condensing unit 62 of the air-conditioning unit 6, and is located below the air-conditioning evaporating unit 61. The air-conditioning condensing unit 62 and the air-conditioning evaporating unit 61 are isolated from each other by a partition plate 63. If the water collecting box 1 is located in the air-conditioning evaporating unit 61, the air-conditioning condensed water will splash out when the vehicle shakes while walking, and will be blown into the air duct by the blower, affecting the comfort of the passengers in the passenger compartment; the air-conditioning condensed water generated by the evaporator above the condenser water pan 64 in the air-conditioning unit 6 drips onto the condenser water pan 64 below, and the air-conditioning condensed water collected in the condenser water pan 64 flows into the water collecting box 1 through the drainage pipe 21 connected thereto, effectively preventing the air-conditioning condensed water from splashing out and being blown into the air duct by the blower, and since the water collecting box 1 is located below the air-conditioning evaporating unit 61, the air-conditioning condensed water flows directly into the water collecting box 1 through the drainage pipe 21 due to gravity, which reduces the complex design and is conducive to the lightweight and reliability of the air conditioner. When the vehicle arrives at the station, the vehicle network sends an arrival signal to the air-conditioning controller. The air-conditioning controller receives the signal and controls the solenoid valve 31, and the solenoid valve 31 opens for drainage. When the vehicle network sends a departure signal to the air-conditioning controller, the air-conditioning controller receives the signal and controls the solenoid valve 6 to close, thereby closing the side drain pipe 3. When the solenoid valve 31 fails and cannot drain water, or manual drainage is required, manual drainage can be performed through the manual drain valve, allowing the vehicle to continue running, further improving reliability.

[0031] This overhead tour bus air-conditioning condensate collection and discharge device can realize the fixed-point discharge of air-conditioning condensate at the station, making the vehicle more intelligent and highly reliable. In addition, when the solenoid valve fails or when needed, the condensate can be discharged through the manual drain valve to ensure the normal operation of the vehicle and further improve reliability.

[0032] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
