Description

Technical Field

[0001] This utility model relates to the field of subway train air conditioning technology, and more specifically to a condensate drainage structure for subway train air conditioning. Background Technology

[0002] As the core carrier of urban public transportation, the comfort of the subway's passenger compartment directly affects the passenger experience. Air conditioning units are key equipment for regulating temperature and humidity.

[0003] However, the existing system is prone to problems with poor drainage of evaporator condensate in high temperature and high humidity environments, which can cause condensate to backflow into the passenger compartment from the return air vent, resulting in water accumulation on the floor, electrical safety hazards, and the risk of passengers slipping.

[0004] In view of this, this utility model proposes a condensate drainage structure for subway train air conditioning to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a condensate drainage structure for subway train air conditioning to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a condensate diversion structure for a subway train air conditioner, including an installation box fixedly installed on the top of the subway car. The bottom of the installation box is provided with a return air vent, which is connected to the inner cavity of the subway car. A water collection tray is fixedly installed on the inner bottom wall of the installation box. A partition is provided inside the water collection tray, which is divided into an evaporator placement area and an electric heating placement area by the partition. An evaporator body is installed inside the evaporator placement area, and an electric heater is installed inside the electric heating placement area. A one-way water conveying component is provided on the surface of the water collection tray. The unidirectional water supply assembly includes a condensate delivery pipe embedded in the surface of the water receiving tray. The inlet end of the condensate delivery pipe corresponds to the inner cavity of the evaporator placement area. A backflow buffer groove is provided at the inlet end of the condensate delivery pipe. A flow-blocking plate is rotatably connected to the inner wall of the backflow buffer groove. A silicone plate is attached to the side of the flow-blocking plate near the evaporator placement area. The silicone plate and the side of the backflow buffer groove near the evaporator placement area are tightly sealed.

[0007] Furthermore, the surface of the partition is provided with flow guide holes, which are used to connect the evaporator placement area and the electric heating placement area.

[0008] As a further description of the above technical solution: the presence of the flow guide hole allows the evaporator placement area and the electric heating placement area to be connected, which to a certain extent balances the water level and pressure of the two areas and avoids excessive local water accumulation.

[0009] Furthermore, a mesh screen is installed on the inner top of the subway car corresponding to the return air vent.

[0010] As a further description of the above technical solution: by setting up the grid, debris can be prevented from entering the installation box through the return air vent, thus protecting the internal equipment.

[0011] Furthermore, the installation box has fresh air inlets on both the front and back, and the inner walls of the fresh air inlets are fitted with protective nets.

[0012] As a further description of the above technical solution: by setting up a protective net, external debris can be prevented from entering the installation box through the fresh air inlet, thus ensuring the normal operation of the air conditioning system.

[0013] Furthermore, the number of condensate delivery pipes is several, and each of the several condensate delivery pipes is divided into two groups, with the two groups of condensate delivery pipes symmetrically distributed on the front and rear sides of the mounting box and the water receiving tray.

[0014] As a further description of the above technical solution: the symmetrical distribution of multiple condensate delivery pipes increases the condensate discharge efficiency, enabling the rapid discharge of condensate generated by the evaporator, effectively preventing condensate from accumulating in the drip tray, thereby reducing the risk of condensate backflow into the passenger compartment from the return air vent, improving the safety and comfort of the subway train passenger compartment, and reducing the occurrence of problems such as floor water accumulation, electrical safety hazards, and passenger slipping.

[0015] Furthermore, the inner wall of the condensate delivery pipe is provided with several anti-backflow plates, with the anti-backflow plates tilted from the inlet of the condensate delivery pipe toward the outlet.

[0016] As a further description of the above technical solution: the inclined setting of the anti-backflow plate further prevents the backflow of condensate, ensuring the smooth discharge of condensate and avoiding the situation where condensate flows back into the carriage.

[0017] The technical effects and advantages of this utility model are as follows: 1. The condensate drainage structure of this subway train's air conditioning system, through the installation of a one-way water delivery component, allows the water pressure to push open the baffle plate when there is condensate in the evaporator placement area, enabling the condensate to be discharged smoothly through the condensate delivery pipe. The silicone plate enhances the sealing effect and prevents condensate backflow. At the same time, the inclined design of the anti-backflow plate further prevents condensate backflow, ensuring smooth condensate drainage and avoiding the situation where condensate flows back into the carriage.

[0018] 2. The condensate drainage structure of the subway train's air conditioning system has drainage holes that allow the evaporator placement area and the electric heating placement area to be connected, which to a certain extent balances the water level and pressure in the two areas and avoids excessive local water accumulation.

[0019] 3. The condensate drainage structure of the subway train's air conditioning system features a mesh grille that prevents debris from entering the installation box through the return air inlet, thus protecting the internal equipment. The protective mesh prevents external debris from entering the installation box through the fresh air inlet, ensuring the normal operation of the air conditioning system.

[0020] 4. The condensate drainage structure of this subway train's air conditioning system, through the symmetrical distribution of multiple condensate delivery pipes, increases the condensate drainage efficiency and can quickly discharge the condensate generated by the evaporator. This effectively prevents condensate from accumulating in the drip tray, thereby reducing the risk of condensate flowing back into the passenger compartment from the return air vent. This improves the safety and comfort of the subway train's passenger compartment and reduces the occurrence of problems such as water accumulation on the floor, electrical safety hazards, and passenger slipping.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The subway train air conditioning condensate guiding structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Reference Figures 1 to 6This utility model provides a condensate drainage structure for a subway train air conditioner, including an installation box 2 fixedly installed on the top of a subway car 1. The bottom of the installation box 2 is provided with a return air vent, which is connected to the inner cavity of the subway car 1. A grid 12 is provided on the inner top of the subway car 1 corresponding to the return air vent.

[0025] The mesh 12 prevents debris from entering the installation box 2 through the return air vent, thus protecting the internal equipment.

[0026] The front and back of the installation box 2 are provided with fresh air inlets, and the inner wall of the fresh air inlets is fitted with a protective net 13.

[0027] By setting up the protective net 13, external debris can be prevented from entering the installation box 2 through the fresh air inlet, thus ensuring the normal operation of the air conditioning system.

[0028] A water receiving tray 3 is fixedly installed on the inner bottom wall of the mounting box 2. A partition 4 is provided inside the water receiving tray 3. The interior of the water receiving tray 3 is divided into an evaporator placement area and an electric heating placement area by the partition 4. An evaporator body 5 is installed inside the evaporator placement area, and an electric heater 6 is installed inside the electric heating placement area. A one-way water conveyance component is provided on the surface of the water receiving tray 3.

[0029] The unidirectional water supply assembly includes a condensate delivery pipe 7 embedded in the surface of the water receiving tray 3. The inlet end of the condensate delivery pipe 7 corresponds to the inner cavity of the evaporator placement area. A backflow buffer groove 8 is provided at the inlet end of the condensate delivery pipe 7. A flow baffle 9 is rotatably connected to the inner wall of the backflow buffer groove 8. A silicone plate 10 is attached to the side of the flow baffle 9 near the evaporator placement area. The silicone plate 10 and the side of the backflow buffer groove 8 near the evaporator placement area are tightly sealed.

[0030] The inner wall of the condensate delivery pipe 7 is provided with several anti-backflow plates 14, and the inclination direction of the anti-backflow plates 14 is from the inlet of the condensate delivery pipe 7 to the outlet.

[0031] The condensate drainage structure of this subway train's air conditioning system uses a one-way water delivery component. When there is condensate in the evaporator placement area, the water pressure pushes open the baffle plate 9, allowing the condensate to be discharged smoothly through the condensate delivery pipe 7. The silicone plate 10 enhances the sealing effect and prevents condensate backflow. At the same time, the inclined design of the anti-backflow plate 14 further prevents condensate backflow, ensuring smooth condensate drainage and preventing condensate from flowing back into the carriage.

[0032] There are several condensate delivery pipes 7, and these pipes are divided into two groups. The two groups of condensate delivery pipes 7 are symmetrically distributed on the front and rear sides of the mounting box 2 and the water receiving tray 3.

[0033] The symmetrical distribution of multiple condensate delivery pipes 7 increases the condensate drainage efficiency, enabling the rapid discharge of condensate generated by the evaporator. This effectively prevents condensate from accumulating in the drip tray 3, thereby reducing the risk of condensate backflow into the passenger compartment from the return air vent. This improves the safety and comfort of the subway train passenger compartment and reduces the occurrence of problems such as floor water accumulation, electrical safety hazards, and passenger slipping.

[0034] The surface of the partition 4 is provided with a flow guide hole 11, which is used to connect the evaporator placement area and the electric heating placement area.

[0035] The condensate drainage structure of the subway train's air conditioning system has drainage holes 11 that allow the evaporator placement area and the electric heating placement area to be connected, which to a certain extent balances the water level and pressure in the two areas and avoids excessive local water accumulation.

[0036] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
