For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0030] Typically, an air conditioning unit drainage device comprises an air conditioning unit, a condensate water collecting device and a condensate water drainage pipe, and the condensate water drainage pipe comprises a roof drainage pipe, a middle drainage pipe and an under-vehicle drainage pipe which are connected in sequence.
[0031] In the drainage device of the related art, the under-vehicle drainage pipe is hung and fixed on the vehicle body frame by multiple fixing devices, that is, the under-vehicle drainage pipe is arranged on the side of the vehicle body frame facing the vehicle running track, and a variety of equipment are usually installed on the side of the vehicle body frame facing the vehicle running track, so it is inevitable that the under-vehicle drainage pipe affects the installation position of other equipment; moreover, when the under-vehicle drainage pipe leaks, the water flowing out of the under-vehicle drainage pipe will penetrate into other equipment, thereby causing damage to other equipment.
[0032] To this end, an embodiment of the present application provides a drainage device, an air-conditioning system and a vehicle. The drainage device, air-conditioning system and vehicle provided in the embodiment of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0033] like Figure 1 As shown, the drainage device according to some embodiments of the present application includes a first drain pipe 10 and a second drain pipe 20. The second drain pipe 20 is suitable for being laid on the base frame 17 of the vehicle body. The first drain pipe 10 is suitable for being laid along the side wall of the vehicle body. One end of the first drain pipe 10 is used to be connected to the air-conditioning unit 1, and the other end is connected to the second drain pipe 20. The second drain pipe 20 is suitable for being connected to a drainage hole (not shown in the figure) at the bottom of the base frame 17 to drain the condensed water of the air-conditioning unit 1 to the outside of the vehicle body.
[0034] In the embodiment of the present application, the second drain pipe 20 is suitable for being laid on the chassis 17 of the vehicle body, one end of the first drain pipe 10 is used to communicate with the air conditioning unit 1, and the other end is communicated with the second drain pipe 20; the second drain pipe 20 is suitable for being communicated with the drainage hole (not shown in the figure) at the bottom of the chassis 17 to drain the condensed water of the air conditioning unit 1 to the outside of the vehicle body. In this way, the condensed water generated by the air conditioning unit 1 can be drained to the bottom of the vehicle body through the first drain pipe 10 and the second drain pipe 20. At the same time, the second drain pipe 20 laid on the chassis 17 of the vehicle body will not affect the installation of other equipment at the bottom of the vehicle body chassis 17, and the second drain pipe 20 is arranged above the chassis 17, away from other devices at the bottom of the chassis 17. When the second drain pipe 20 leaks, it will not cause damage to other equipment, thereby improving the safety of the entire vehicle.
[0035] In a specific application, the vehicle body is mainly composed of a chassis 17, side walls and a roof. The second drain pipe 20 is arranged above the chassis 17, and an interior trim panel is also arranged above the second drain pipe 20, so as to protect the second drain pipe 20 and make it more beautiful.
[0036] It can be understood that the cross-section of the second drain pipe 20 can be circular, polygonal, etc., and those skilled in the art can select it according to actual needs, and the embodiment of the present application does not limit this.
[0037] In a specific application, the width of the second drain pipe 20 can be designed according to the maximum amount of water flowing through the drainage device, and the height of the second drain pipe 20 can be designed according to the height between the vehicle body chassis 17 and the interior trim panel.
[0038] In a specific application, an interior panel is also provided on the side of the side wall facing the interior of the vehicle body, and a first drain pipe 10 is laid between the side wall frame and the interior panel. One end of the first drain pipe 10 is used to connect with the air-conditioning unit 1, and the other end is connected with the second drain pipe 20.
[0039] It is understandable that the first drain pipe 10 can be connected to the second drain pipe 20 by means of a clamp connection (groove connection), or by means of a ferrule connection, a flange connection, a compression connection, a threaded connection, a socket connection, or other pipeline connection methods. Those skilled in the art can select according to actual needs, and the embodiments of the present application do not limit this. After the first drain pipe 10 is connected to the second drain pipe 20, waterproof treatment is performed by coating with waterproof glue or the like.
[0040] It can be understood that, taking the drainage device installed on a straddle-type monorail train as an example, the car body runs above the vehicle track 4, and the underframe 17 of the car body is located in the area above the vehicle track 4. A plurality of drainage holes (not shown in the figure) are provided, and the drainage holes pass through the underframe 17. The second drainage pipe 20 is connected to the drainage holes so that when the condensed water of the air-conditioning unit 1 is discharged to the outside of the car body, the condensed water flows to the vehicle track 4, thereby preventing the condensed water from falling directly to the ground and affecting pedestrians or the environment.
[0041] Meanwhile, in the related art, the first undercarriage drainage pipe 33 is arranged on the side of the undercarriage 17 facing the vehicle running track 4. When the first undercarriage drainage pipe 33 is installed, a hole needs to be punched at the intersection of the undercarriage and the vehicle side wall, which will reduce the structural strength of the connection between the undercarriage and the side wall. However, the hole punched in the middle of the undercarriage 17 in the embodiment of the present application is closer to the middle position than the punching position in the related art, which has less impact on the strength of the vehicle body and improves the safety of the whole vehicle.
[0042] Alternatively, if Figure 2 As shown, the drainage device also includes a water collection mechanism 30 , which is suitable for being connected to the air-conditioning unit 1 to collect condensed water generated by the air-conditioning unit 1 , and one end of the first drainage pipe 10 away from the second drainage pipe 20 is connected to the water collection mechanism 30 .
[0043] In an embodiment of the present application, the drainage device also includes a water collecting mechanism 30, which is connected to the air-conditioning unit 1 and is used to collect condensed water generated by the air-conditioning unit 1. The end of the first drain pipe 10 away from the second drain pipe 20 is connected to the water collecting mechanism 30, thereby centrally collecting the condensed water in the air-conditioning unit 1.
[0044] In addition, if Figure 2 As shown, the air-conditioning unit 1 is installed on the top of the vehicle body, and part of the air-conditioning unit 1 is exposed on the top of the vehicle body. In rainy and snowy weather, part of the rainwater will penetrate into the vehicle body along the air-conditioning unit. Therefore, by setting a water collection mechanism 30, the rainwater that penetrates along the air-conditioning unit 1 can be further collected so as to be uniformly guided to the first drain pipe 10 to prevent it from flowing into the vehicle body.
[0045] In a specific application, the water collection mechanism 30 is disposed at the water outlet of the air conditioning unit 1 and is detachably connected to the air conditioning unit 1. Since the amount of condensed water generated by the air conditioning unit 1 is relatively small when the power consumption is low, a small amount of condensed water will adhere to the inside of the pipe, which is not conducive to the discharge of condensed water. The water collection mechanism 30 is set to collect the condensed water of the air conditioning unit 1, and at the same time, it can also collect rainwater that penetrates along the air conditioning unit 1.
[0046] In some embodiments of the present application, the water collection mechanism 30 may be made of hard plastic, aluminum alloy material, carbon fiber material, etc., so as to reduce the weight of the water collection mechanism 30 itself while ensuring the bearing capacity of the condensed water.
[0047] It can be understood that the water collection mechanism 30 can be detachably connected to the air-conditioning unit 1 by means of threaded connection, snap connection, flange connection, etc., and those skilled in the art can select according to actual needs, and the embodiments of the present application do not limit this.
[0048] In some embodiments of the present application, the water collection mechanism 30 can be integrated into the air-conditioning unit 1 and formed integrally with the outer shell of the air-conditioning unit 1, thereby reducing operations during installation and improving installation efficiency.
[0049] Optionally, the drainage device further includes an adapter 40, which includes a water inlet 411 and a water outlet 421, the water inlet 411 is connected to the water collecting mechanism 30, the water outlet 421 is connected to the first drainage pipe 10, and the position of the water outlet 421 is adjustable.
[0050] In an embodiment of the present application, the drainage device also includes an adapter 40, which includes a water inlet 411 and a water outlet 421. The water inlet 411 is connected to the water collection mechanism 30, and the water outlet 421 is connected to the first drain pipe 10. The position of the water outlet 421 is adjustable. During the installation process, it can be adjusted according to the installation position of other adjacent equipment so that the first drain pipe 10 connected to the water outlet 421 avoids the installation position of other adjacent equipment.
[0051] Specifically, other equipment will be installed near the air-conditioning unit 1 of the vehicle body, and the positions of other equipment will affect the installation path of the drainage device. In order to flexibly adjust the installation path of the drainage device, an adapter 40 is set between the water collecting mechanism 30 and the first drain pipe 30. The water inlet 411 of the adapter 40 is connected to the water collecting mechanism 30, and the water outlet 421 is connected to the first drain pipe. The position of the water outlet 421 is adjustable, thereby adjusting the installation position of the first drain pipe 10 connected to the water outlet 421 to avoid interference with the installation positions of other adjacent equipment.
[0052] It can be understood that the adapter 40 and the water collection mechanism 30 as well as the adapter 40 and the first drain pipe 10 can be connected by flange connection, threaded connection, socket connection or other connection methods. Those skilled in the art can choose according to actual needs, and the embodiments of the present application do not limit this.
[0053] Exemplarily, the adapter 40 can be configured as an elbow joint, one end of which is connected to the water collecting device 30, and the other end of which is connected to the first drain pipe 10. When installing the adapter 40, first install one end of the elbow joint on the water collecting device 30, and then flexibly adjust the position of the other end of the elbow joint according to the position of the first drain pipe 10, so that the other end of the elbow joint is connected to the first drain pipe 10, so that the installation position of the first drain pipe 10 is adjusted accordingly.
[0054] Optionally, the adapter 40 includes a first connecting member 41 and a second connecting member 42, the second connecting member 42 is movably connected to the first connecting member 41, an end of the second connecting member 42 away from the first connecting member 41 is provided with a water outlet 421, and an end of the first connecting member 41 away from the second connecting member 42 is provided with a water inlet 411.
[0055] In the embodiment of the present application, the adapter 40 includes a first connector 41 and a second connector 42, the second connector 42 is movably connected to the first connector 41, a water outlet 421 is provided at one end of the second connector 42 away from the first connector 41, and a water inlet 411 is provided at one end of the first connector 41 away from the second connector 42. In this way, the adapter 40 is connected to the water collection mechanism 30 through the water inlet 411 on the first connector 41, and is connected to the first drain pipe 10 through the water outlet 422 on the second connector 42. Since the first connector 41 and the second connector 42 are movably connected, the position of the water outlet 421 can be adjusted through the relative movement between the first connector 41 and the second connector 42.
[0056] Specifically, the first connecting member 41 is at least partially nested in the second connecting member 42, so that when the first connecting member 41 is connected to the second connecting member 42, the second connecting member 42 can move relative to the first connecting member 41, thereby adjusting the position of the water outlet 421 on the second connecting member 42. For example, the adapter 40 is a ball joint or a 360° rotating universal joint.
[0057] Optionally, the first drain pipe 10 includes a first pipe 11 and a second pipe 12 , one end of the first pipe 11 is connected to the water outlet 421 , the other end of the first pipe 11 is connected to the second pipe 12 , and the end of the second pipe 12 away from the first pipe 11 is connected to the second drain pipe 20 .
[0058] Specifically, one end of the first drain pipe 10 is connected to the water outlet 421 of the adapter 40, and the other end is connected to the second drain pipe 20. Since the air-conditioning unit 1 is usually arranged on the top of the vehicle body, and the second drain pipe 20 is arranged on the chassis 17 of the vehicle body, the laying path of the first drain pipe 20 needs to include the position of the roof and the entire side wall on one side of the vehicle body. Since the laying path is long and the laying path includes the corner where the roof and the side wall are connected, dividing the first drain pipe 10 into a first pipeline 11 and a second pipeline 12 can improve the installation flexibility of the first drain pipe 10. At the same time, it does not affect the internal space of the car and can make the laid first drain pipe 10 more flat.
[0059] It can be understood that, taking the drainage device installed in a rail train as an example, the first pipe 11 is installed on the top of the car body, and the second pipe 12 is installed on the side wall of the car body. The first pipe 11 can be made of a plastic hose to make it more convenient to lay, and the second pipe 12 can be made of a plastic hose, a plastic hard pipe, an alloy pipe, etc. Technical personnel in this field can choose according to actual needs, and the embodiments of the present application do not limit this.
[0060] It can be understood that the first pipeline 11 and the second pipeline 12 can be connected by flange connection, threaded connection, socket connection and other connection methods. Those skilled in the art can choose according to actual needs, and the embodiments of the present application do not limit this.
[0061] Optionally, the drainage device further includes a water outlet pipe 50 , which is passed through the drainage hole, with one end of the water outlet pipe 50 being connected to the second drainage pipe 20 , and the other end being exposed on a side of the base frame away from the second drainage pipe 20 .
[0062] In the embodiment of the present application, the drainage device also includes a water outlet pipe 50, which is inserted into the drainage hole. One end of the water outlet pipe 50 is connected to the second drain pipe 20, and the other end is exposed on the side of the base frame away from the second drain pipe 20. The water outlet pipe 50 can prevent the water flowing through the drainage device from directly contacting the base frame 17, thereby further improving the reliability of the drainage device.
[0063] Specifically, the second drain pipe 20 is directly connected to the drain hole provided on the bottom frame 17, which may cause the water flowing through to damage the bottom frame 17 for a long time, thereby reducing the safety of the vehicle body. Therefore, a water outlet pipe 50 is provided to penetrate the drain hole, one end of the water outlet pipe 50 is connected to the second drain pipe 20, and the other end is exposed to the side of the bottom frame away from the second drain pipe 20, so as to guide the condensed water in the second drain pipe 20 to the outside of the vehicle body for discharge.
[0064] It is understandable that the water outlet pipe 50 can be connected to the second drain pipe 20 by welding connection, threaded connection, etc. Those skilled in the art can choose according to actual needs, and the embodiment of the present application does not limit this.
[0065] Optionally, the second drain pipe 20 further includes a connector 21 , which is disposed between the second drain pipe 20 and the first drain pipe 10 , with one end of the connector 21 being connected to the second drain pipe 20 , and the other end of the connector 21 being connected to the first drain pipe 10 .
[0066] In the embodiment of the present application, the second drain pipe 20 also includes a connecting head 21, which is arranged between the second drain pipe 20 and the first drain pipe 10. One end of the connecting head 21 is connected to the second drain pipe 20, and the other end is connected to the first drain pipe 10, thereby facilitating the connection between the second drain pipe 20 and the first drain pipe 10 and improving the stability of the connection.
[0067] Specifically, the second drain pipe 20 is laid on the vehicle body frame 17, and one end of the first drain pipe 10 connected to the second drain pipe 20 is set in the side wall of the vehicle body. The second drain pipe 20 and the first drain pipe 10 form an approximately right angle. In specific applications, in order to facilitate the connection between the two, a connector 21 is set between the second drain pipe 20 and the first drain pipe 10, one end of the connector 21 is connected to the second drain pipe 20, and the other end is connected to the first drain pipe 10.
[0068] It can be understood that the connector 21 can be connected to the second drain pipe 20 by welding, threaded connection, etc. Those skilled in the art can choose according to actual needs, and the embodiment of the present application does not limit this.
[0069] In some embodiments of the present application, the connector 21 is an arc-shaped connector. When the condensed water flowing out of the first drain pipe 10 flows approximately vertically into the second drain pipe 20, the water flow will produce impact and cause the water flow to be blocked. The arc-shaped connector can reduce the impact of the water flow and make the water flow smoother.
[0070] In some embodiments of the present application, the second drain pipe 20, the connecting head 21, and the water outlet pipe 50 are produced by integral molding, thereby improving the sealing of the drainage device at the bottom and further improving the safety of the entire vehicle.
[0071] Optionally, an embodiment of the present application further provides an air-conditioning system, comprising an air-conditioning unit 1 and the drainage device in the above embodiment, wherein the drainage device is connected to the air-conditioning unit 1.
[0072] According to the embodiment of the present application, the air conditioning system includes a drainage device, which includes a first drainage pipe 10 and a second drainage pipe 20. The second drainage pipe 20 is suitable for laying on the chassis 17 of the vehicle body. The first drainage pipe 10 is suitable for laying along the side wall of the vehicle body. One end of the first drainage pipe 10 is used to communicate with the air conditioning unit 1, and the other end is connected to the second drainage pipe 20. The second drainage pipe 20 is suitable for communicating with the drainage hole at the bottom of the chassis 17 to drain the condensed water of the air conditioning unit 1 to the outside of the vehicle body. In this way, the second drainage pipe 20 laid on the chassis 17 of the vehicle body will not affect the installation of other equipment under the chassis 17 of the vehicle body, and when the drainage device leaks, the outflowing water will not cause damage to other equipment, thereby improving the safety of the entire vehicle.
[0073] It should be noted that the air conditioning system in the embodiment of the present application may include the drainage device in any of the above embodiments. The specific structure of the drainage device can be found in the above content, and the embodiment of the present application will not be repeated here.
[0074] Optionally, the air conditioning unit 1 is provided with a plurality of drainage outlets, each drainage outlet is provided with a corresponding drainage device, and the plurality of drainage devices are arranged at intervals in the vehicle body.
[0075] Specifically, taking the air-conditioning system installed in the vehicle as an example, an air-conditioning unit 1 is arranged in a single compartment of the vehicle, and there are several drain outlets on the air-conditioning unit 1. A drainage device is arranged corresponding to each drain outlet, that is, each water outlet of the air-conditioning unit 1 corresponds to one drainage channel, and several drainage devices are arranged at intervals in the vehicle body according to the positions of the specific corresponding drain outlets, thereby improving the drainage capacity of the air-conditioning system and the flexibility of the layout of the drainage devices.
[0076] Optionally, a plurality of drainage devices are suitable for being arranged on both sides of the vehicle body along the width direction, and the second drainage pipes in two drainage devices opposite to each other along the width direction are connected to the same drainage hole.
[0077] It can be understood that the vehicle body has a certain length, width and height, and the length of the vehicle body is greater than the width and height of the vehicle body, wherein the direction from the front of the vehicle to the parking space is the length direction, and the width direction of the vehicle body is perpendicular to the length direction.
