Referring to fig. 1 and 2, fig. 1 is a perspective view of a water receiving assembly according to an embodiment of the present disclosure, and fig. 2 is an exploded perspective view of the water receiving assembly according to the embodiment of the present disclosure. The water receiving assembly 100 is applied to an inter-row air conditioner which comprises an evaporator 200, and is connected to the bottom of the evaporator in a specific application. The water receiving assembly 100 comprises a water receiving tray 1, a flow guide piece 2 and a water outlet maintenance cover plate 3, wherein the water receiving tray 1 is provided with a first accommodating groove 10, the first accommodating groove 10 is used for collecting condensed water, and the water outlet is formed in the bottom wall 11 of the first accommodating groove 10. The water guide piece 2 is arranged in the first accommodating groove 10 and is enclosed with the water receiving tray 1 to form a first cavity 300, the first cavity 300 is provided with a first liquid through port 21 and a second liquid through port 22, so that the first liquid through port 21, the second liquid through port 22 and the water outlet are sequentially communicated to form a channel for flowing condensed water, and at least part of condensed water in the first accommodating groove 10 can be discharged out of the water receiving tray 1 through the first liquid through port 21, the first cavity 300, the second liquid through port 22 and the water outlet in sequence. The drain port maintenance cover plate 3 is connected to the water pan 1 and covers the drain port to form a second cavity 400 (shown in fig. 3), the drain port maintenance cover plate 3 is provided with a third liquid passing port 31, the second cavity 400 and the drain port are sequentially communicated to form a channel for flowing condensed water, and at least part of condensed water in the first accommodating groove 10 can be sequentially discharged out of the water pan 1 through the third liquid passing port 31, the second cavity 400 and the drain port.
When the water receiving assembly 100 is installed in a train air conditioner, the first liquid passing port 21 and the second liquid passing port 22 are respectively located on both sides (air outlet side and air return side) of the evaporator, and when the air driven by the fan flows through the evaporator, the first liquid passing port 21, the first cavity 300, the second liquid passing port 22 and the water outlet are communicated to form a passage for flowing condensate of a negative pressure region (the negative pressure region is a region with air pressure lower than the existing atmospheric pressure), and the third liquid passing port 31, the second cavity 400 and the water outlet are communicated to form a passage for flowing condensate of the negative pressure region. When the evaporator generates condensed water, part of the condensed water flows to the water receiving tray 1 along the outer surface of the flow guide piece 2 under the action of self gravity, and flows to the water outlet through the first liquid through port 21, the first cavity 300 and the second liquid through port 22 in sequence, and is discharged out of the water receiving tray 1 through the water outlet; part of the condensed water flows to the water receiving tray 1 along the outer surface of the flow guide piece 2 under the action of self gravity, flows to the water outlet through the third liquid passing port 31 and the second cavity 400, and is discharged out of the water receiving tray 1 through the water outlet.
When the water receiving assembly 100 is installed in a train air conditioner, the first liquid through port 21 may be located on the air outlet side of the evaporator 200, and the second liquid through port 22 and the water outlet port may be located on the air return side of the evaporator 200; the first liquid passage 21 may be located on the return air side of the evaporator 200, and the second liquid passage 22 and the drain port may be located on the air outlet side of the evaporator 200. Referring to fig. 3, fig. 3 is a cross-sectional view of a water receiving assembly and an evaporator according to an embodiment of the present disclosure, and this embodiment is described by taking an example that when the water receiving assembly 100 is installed in a train air conditioner, the first liquid passing port 21 is located on an air outlet side of the evaporator 200, and the second liquid passing port 22 and the water discharging port are located on a return air side of the evaporator 200. When the fins on the air outlet side of the evaporator generate condensed water, the condensed water flows to the water receiving tray 1 along the outer surface of the flow guide piece 2 under the action of self gravity, and flows to the water outlet through the first liquid through port 21, the first cavity 300 and the second liquid through port 22 in sequence and is discharged from the water outlet; when the fins on the air return side of the evaporator generate condensed water, the condensed water flows to the water receiving tray 1 along the outer surface of the flow guide piece 2 under the action of self gravity, flows to the water outlet through the third liquid through opening 31 and is discharged from the water outlet.
When the train air conditioner provided with the water receiving assembly works, the first liquid through port 21, the first cavity 300, the second liquid through port 22 and the water outlet are communicated to form a channel for flowing condensed water in a negative pressure area, and the third liquid through port 31, the second cavity 400 and the water outlet form a channel for flowing the condensed water in the negative pressure area, so that the condensed water generated by the evaporator flows in the channel, the flowing resistance of the condensed water in the water receiving tray 1 is reduced, and the condensed water in the whole water receiving tray 1 can smoothly flow to the water outlet and is discharged out of the water receiving tray 1. Meanwhile, because the area of the drain outlet is under the negative pressure of the atmosphere, when the condensed water circulates to the outside of the air conditioner through the drain pipe, the condensed water can bubble at the drain outlet under the influence of the atmospheric pressure.
In this embodiment, the bottom wall of the drip tray 1 is provided with not only the self-weight drain port 101 but also the water pump drain port 102, and condensed water can be drained from the self-weight drain port 101 by its own weight or from the water pump drain port 102 by the action of the water pump. It will be appreciated that in other embodiments, only one drain may be provided, through which the condensate may drain under its own weight and action, or under the action of a water pump.
Further, except for the open third liquid through port 31 of the drain port maintenance cover plate 3, the drain port is used for the circulation of condensed water, and the rest part of the drain port maintenance cover plate completely covers the drain port to form a negative pressure area between the operation of the air conditioner between the columns and the water receiving disc 1, so that the turbulence condition of air flow to the condensed water in the first liquid circulation channel is reduced, meanwhile, the bubble splashing condition is avoided when the drain port is connected to the positive pressure of the air outside the air conditioner through the drain pipe, and the negative pressure area can also be constructed by other sheet metal structures or other materials or structural forms.
With continued reference to fig. 2, the water tray 1 includes a bottom wall 11 and a side wall 12, and the side wall 12 is disposed around the bottom wall 11 to form a first accommodating groove 10. The flow guide part 2 comprises a cover plate 23 and a folded edge 24, and the folded edge 24 is arranged around the periphery of the cover plate 23 to form a second accommodating cavity. During the equipment, set up water conservancy diversion spare 2 in first holding tank 10, make the hem 24 of water conservancy diversion spare 2 be connected with the diapire 11 of water collector 1, and then make the diapire of apron 23, hem 24 and first holding tank 10 enclose to close and form first cavity 300, first logical liquid mouth 21 and second logical liquid mouth 22 are all seted up in the two relative hem 24 of water conservancy diversion spare 2.
This application separates evaporimeter return air side malleation and evaporimeter air-out side negative pressure through the cavity that water conservancy diversion spare and water collector are constituteed, has guaranteed also can smoothly discharge when condensate water reserves are many in the water collector 1, and the positive pressure air current that reduces the evaporimeter return air side is to the comdenstion water circulation production interference. Simultaneously, the diapire 11 that water collector 1 can be extended to through hem 24 to water guide 2 of this application, and then make the comdenstion water flow smoothly to water collector 1 through hem 24 in, avoid appearing cutoff and water droplet and hang and lead to the condition of blowing by the air current vortex at water guide 2.
Further, the water receiving assembly 100 further includes a water blocking member 4, and the water blocking member 4 is connected to the cover plate 23 and is located at an upper portion of the first liquid passing port 21. Because the first liquid through port 21, the first cavity 300, the second liquid through port 22 and the water outlet form a channel in which a tiny part of air current flows, the arrangement of the water blocking piece 4 prevents the condensate water flowing to the flow guide piece 2 on the evaporator fin from flowing down the water receiving tray 1 from the first liquid through port 21 to cause water drop suspension and water flow suspension, thereby causing the water blowing condition at the first liquid through port 21. In the embodiment, the water blocking piece 4 is formed by bending the folded edge 24 upwards, and the water blocking piece 4 is formed by bending the folded edge 24 upwards, so that other materials are not required to be added, and the product cost is reduced. It will be appreciated that in other embodiments the water deflector 4 may be a separate component, with the cover plate 23 attached by welding.
The principle and practical experiments based on the interaction relation of fluid, condensate water gravity and airflow interference resistance prove that the gap proportion of the better liquid flow channel is obtained, the ratio of the cross section area of the first liquid through port 21 for flowing of the condensate water to the cross section area of the second liquid through port 22 for flowing of the condensate water is K2, K2 is more than or equal to 2, the ratio of the cross section area of the second liquid through port 22 for flowing of the condensate water to the cross section area of the third liquid through port 31 for flowing of the condensate water is K1, and K1 is more than or equal to 2, so that the situation that the local wind speed is too high at the first liquid through port 21 of the flow guide piece 2 is prevented, and if the local wind speed is too high at the first liquid through port 21, the condensate water on the air outlet side of the evaporator cannot smoothly flow to the water outlet under the influence of the airflow resistance; meanwhile, the situation that water is blown due to overhigh local wind speed when the water level of condensed water is higher than the third liquid passing opening 31 is prevented.
If the ratio K2 of the flowing sectional area of the condensed water of the first liquid through port 21 to the flowing sectional area of the condensed water of the second liquid through port 22 is less than 2, and the ratio K1 of the flowing sectional area of the condensed water of the second liquid through port 22 to the flowing sectional area of the condensed water of the third liquid through port 31 is less than 2, the flow disturbance of the air flow to the condensed water in the channel to the water outlet is obvious, and the condensed water splashing condition can also occur in the first liquid through port 21 of the flow guide part 2 positioned on the air outlet side of the evaporator in serious cases; if the ratio K2 of the cross-sectional area of the first liquid passing port 21 for flowing of the condensed water to the cross-sectional area of the second liquid passing port 22 for flowing of the condensed water is greater than or equal to 2, and the ratio K1 of the cross-sectional area of the second liquid passing port 22 for flowing of the condensed water to the cross-sectional area of the third liquid passing port 31 for flowing of the condensed water is greater than or equal to 2, the drainage effect is better, and no turbulent flow is caused by blowing water.
Further, the water receiving tray 1 is further provided with an overflow gap 13, and the water receiving assembly 100 further comprises a water sensor which is arranged below the overflow gap 13 and used for giving an alarm when the overflow gap 13 overflows. For example, when the outlet drainage is not smooth or is blockked up, the water level height that the comdenstion water gathered can spill over from overflow breach 13 when reaching overflow breach 13 of water collector 1, and at this moment, the water logging sensor can be triggered, sends the warning, and the suggestion drainage trouble needs to be maintained, avoids the comdenstion water large tracts of land to spill over the condition from water collector 1.
The water receiving assembly 100 further comprises a water level switch and a water level switch fixing support 5, the water level switch fixing support 5 is arranged on the water receiving tray 1, the water level switch is mounted on the water level switch fixing support 5, and the water level switch can detect the water level in the water receiving tray 1 so as to give an alarm according to the water level condition in the water receiving tray 1. For example, when the water outlet is blocked or the water drainage is not smooth, so that the water level in the water receiving tray 1 exceeds a preset value, the water level switch gives an alarm, so that maintenance personnel can dredge the water outlet in time, and the condition that the condensed water overflows from the water receiving tray 1 in a large area when the water outlet is blocked or the water drainage is not smooth is avoided. Wherein, the lowest water level that can make water level switch send out the warning is less than the lowest water level of overflow breach 13.
Correspondingly, the application also discloses a train room air conditioner, which is shown in fig. 4 and comprises an evaporator and the water receiving assembly 100 described in any of the above embodiments, wherein the water receiving assembly 100 is received at the bottom of the evaporator. Specifically, the end plate lug connection of evaporimeter deviates from a side surface of first holding tank in water conservancy diversion spare 2, and first logical liquid mouth 21 is located the air-out side of evaporimeter 200, and second logical liquid mouth 22 and outlet are located the return air side of evaporimeter 200, and the return air side of evaporimeter 200 is also located to water level switch and overflow breach 13 simultaneously.
When the fins on the air outlet side of the evaporator 200 generate condensed water, the condensed water flows to the flow guide member 2 under the action of gravity, is collected into the water receiving tray 1 from the folded edge 24, flows to the water outlet through the first liquid through port 21, the first cavity and the second liquid through port 22, and is discharged from the water outlet.
The outlet is arranged on the air return side of the evaporator, so that the lower-temperature condensed water flows to the outlet in the direction opposite to the direction of the higher-temperature air return flow, convection heat transfer is formed, the heat exchange efficiency is improved, and the low air return temperature is prevented. Simultaneously, because the evaporimeter goes out the regional fan cavity that is equipped with of wind side for the return air side of evaporimeter is relative to the wind side maintenance space bigger, and the return air side of evaporimeter is located outlet and water level switch to this embodiment, when dirty stifled phenomenon or water level switch break down appear in the outlet, it is more convenient to maintain, and also the wiring of the water level switch of being more convenient for and water sensor.
Further, when the water receiving tray 1 is installed, the water receiving tray 1 inclines to a certain inclination towards the water outlet of the air return side, namely, the horizontal height of one side of the water receiving tray 1 provided with the water outlet is lower than the horizontal height of one side of the water receiving tray 1 not provided with the water outlet, so that the condensed water can overcome the disturbance resistance of the air flow under the influence of the self gravity, smoothly flows towards the water outlet and is discharged from the water outlet. This application is in the extreme low of water collector 1 through making the outlet, has reduced the influence of air current resistance to comdenstion water exhaust, and simultaneously, the lower condensate flow of the lower temperature of down flowing forms the convection heat transfer to outlet direction and the higher return air current opposite direction of the higher temperature of the upward flow, increases heat exchange efficiency, and further cooling improves heat exchange efficiency and reduces the return air temperature.
In another embodiment, after the water receiving assembly 100 is assembled with the evaporator, the first liquid passing opening 21 may be located on the air return side of the evaporator, and the second liquid passing opening 22 and the water discharge opening are located on the air outlet side of the evaporator, although the water level switch and the overflow notch 13 may also be located on the air outlet side of the evaporator.
