[0038] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] As Figures 1 to 10 shown, the present application provides a drainage device, which is arranged at one side of a drainage hole of an evaporator assembly 200, and comprises: a shell 1, which comprises a containing cavity 11 and a shell inlet 12 and a shell outlet 13 communicating with the containing cavity 11; a sponge 2, which is arranged at the shell outlet 13; and a vane assembly 3, which is rotatably arranged in the containing cavity 11 and located between the shell inlet 12 and the sponge 2 about a center line of the vane assembly 3; wherein the distance between the center line of the vane assembly 3 and the top surface of the containing cavity 11 is less than the distance between the center line of the vane assembly 3 and the bottom surface of the containing cavity 11; the vane assembly 3 comprises a plurality of vane parts 31 movably arranged in the direction of approaching or moving away from the center line of the vane assembly 3; when two vane parts 31 respectively move to approach the top surface and the bottom surface of the containing cavity 11, the two vane parts 31 respectively keep in contact with the top surface and the bottom surface of the containing cavity 11 to divide the containing cavity 11 into an inlet cavity 14 and an outlet cavity 15 respectively communicating with the shell inlet 12 and the shell outlet 13.

[0040] In this way, the drainage device of the present application is installed on the bottom plate 100 of the air conditioner and connected with the drainage hole of the evaporator assembly 200 of the air conditioner, so as to drive the vane assembly 3 to rotate by using the pressure difference between the gas pressure inside the evaporating cavity 203 of the evaporator assembly 200 and the air pressure outside, so as to make the condensed water discharged from the drainage hole and the hot air outside uniformly exchange heat at the sponge 2, so as to pre-cool the hot air outside entering the inside of the evaporating cavity 203, and the cooled air flows into the cabin of the air conditioner with the air conditioner through the air outlet of the air conditioner after passing through the evaporator assembly 200, thereby avoiding the problem of the decline of the refrigeration capacity of the evaporator assembly caused by the direct suction of the hot air outside into the evaporating cavity due to the direct communication between the drainage hole of the evaporating cavity 203 of the evaporator assembly and the outside, solving the problem of the weakening of the internal circulation heat exchange capacity caused by the pressure loss of the evaporating cavity 203 of the evaporator assembly, solving the problem of the poor refrigeration capacity of the air conditioner in the prior art caused by the limitation of the battery on the vehicle, and being capable of increasing the humidity of the cooled air, solving the problem of the decline of the human comfort caused by the dry air in the cabin, improving the energy efficiency of the air conditioner, and reducing the energy loss of the air conditioner.

[0041] AsFigure 4 As shown in the drawings, the vane assembly 3 comprises a bearing 32 mounted on the shell 1, and a rotating shaft 33, around which the plurality of vane portions 31 are arranged uniformly and connected with the rotating shaft 33, and the rotating shaft 33 is rotatably mounted on the bearing 32.

[0042] As shown in the drawings, Figure 4 The vane portion 31 comprises a sleeve 34, a telescopic rod 35 and an elastic member 36, one end of the sleeve 34 is connected with the rotating shaft 33, the other end of the sleeve 34 extends away from the rotating shaft 33, the elastic member 36 is arranged in the sleeve 34, a part of the telescopic rod 35 is located in the sleeve 34 and in contact with the elastic member 36, and the other part of the telescopic rod 35 extends away from the sleeve 34.

[0043] Specifically, the elastic member 36 is a compression spring; and / or the vane portion 31 comprises a water scooping baffle 37 arranged at one end of the telescopic rod 35 away from the elastic member 36 and extending towards the front side of the vane portion 31 in the rotating direction; and / or the vane portion 31 comprises a pulley 38 rotatably arranged at one end of the telescopic rod 35 away from the elastic member 36 for contacting the cavity wall of the accommodating cavity 11.

[0044] As shown in the drawings, Figure 2 and Figure 3 The bottom surface of the accommodating cavity 11 is provided with a water baffle 4 located between the vane assembly 3 and the sponge 2 to separate the bottom surface of the accommodating cavity 11 into a water inlet surface 16 and a water outlet surface 17.

[0045] Preferably, at least part of the water inlet surface 16 gradually decreases in height in the direction away from the shell inlet 12; and / or at least part of the water outlet surface 17 gradually decreases in height in the direction away from the shell inlet 12.

[0046] As shown in the drawings, Figure 2 and Figure 3 The accommodating cavity 11 is provided with a slide rail 5 for guiding the vane assembly 3, the slide rail 5 is located on the side of the vane assembly 3 close to the shell inlet 12, and the slide rail 5 is a partial eccentric circular ring; wherein the slide rail 5 separates the inlet cavity 14 into an evaporator communication cavity 18 and a first vane cavity 19, and the slide rail 5 is provided with an avoidance through slot 51 for communicating the evaporator communication cavity 18 and the first vane cavity 19.

[0047] Preferably, the sponge 2 is a hydrophilic honeycomb explosion sponge, which can make the condensed water adhere uniformly, increase the heat exchange area between the condensed water and the outside air, and make the heat exchange more sufficient; and / or the shell 1 comprises a front cover plate 101, a lower cover plate 102, a rear cover plate 103 and an upper cover plate 104 connected in sequence around a predetermined center line to jointly enclose the accommodating cavity 11, the shell inlet 12 and the shell outlet 13.

[0048] AsFigure 5 As shown, the blade assembly 3 of the drainage device includes eight blade sections 31, which are arranged evenly in sequence around the circumference of the rotating shaft 33.

[0049] like Figure 5 As shown, the blade portion 31 that contacts the bottom surface of the receiving cavity 11 is the first blade portion 311, and the blade portion 31 that contacts the top surface of the receiving cavity 11 is the second blade portion 312. The first blade portion 311 and the second blade portion 312 together divide the eccentric cylindrical cavity where the blade assembly 3 is located into a first blade cavity 19 and a second blade cavity located on the side of the first blade cavity 19 away from the housing inlet 12. The evaporator connecting cavity 18 has a negative pressure set to P1, and the air pressure of the outside air is P0. Since the slide rail 5 is provided with a clearance groove 51, the first blade cavity 19 on the side closer to the housing inlet 12 is connected to the evaporation cavity 203, so the air pressure of the first blade cavity 19 is also P1; while the second blade cavity on the side away from the housing inlet 12 is connected to the outside air, so the air pressure of the second blade cavity is P0.

[0050] like Figure 5 As shown, the pressure difference between the first blade cavity 19 and the second blade cavity exerts a torque on the blade assembly 3.

[0051] Assuming the pressure acting on the blade section 31 is F, the blade area of ​​the blade section 31 is S, the length of the blade section 31 is L, and the width of the blade section 31 is D, then S = LD; from the pressure-force relationship formula (P = F / S) and the torque calculation formula (T = FL), we can obtain T = PDL. 2 .

[0052] Wherein, the first torque T1 on the first blade section 311 is (P0-P1)*D1*L1 2 The second torque T2 on the second blade section 312 is (P0-P1)*D2*L2 2 The first torque T1 is clockwise, and the second torque T2 is counterclockwise.

[0053] like Figure 6 As shown, since the width of the first blade portion 311 is equal to the width of the second blade portion 312, i.e., D1 = D2, and the length L1 of the first blade portion 311 is greater than the length L2 of the second blade portion 312, we can conclude that T1 > T2. Furthermore, except for the pressure difference between the two sides of the first blade portion 311 and the second blade portion 312, the pressure on the two sides of the other blade portions 31 is in equilibrium.

[0054] As can be seen from the above, the total clockwise torque Ttotal experienced by the entire blade assembly 3 is equal to T1 - T2. Therefore, when the air conditioner is running, the blade assembly 3 of the drainage device of the present invention will rotate clockwise under the drive of the negative pressure in the evaporation chamber 203.

[0055] As Figure 3 shown, when the air conditioner is running, the condensed water generated on the evaporator assembly 200 will flow into the water inlet surface 16 of the drain device along the evaporator drain groove 204, and when the blade assembly 3 rotates clockwise, the condensed water on the water inlet surface 16 is brought up by the water scoop baffle 37 and evenly sprayed on the sponge 2 to wet the sponge 2; At this time, the outside air can exchange heat with the condensed water on the sponge 2 while being sucked in, and the air after heat exchange is discharged from the air outlet of the air conditioner into the driver cabin of the vehicle installed with the air conditioner, and the condensed water after heat exchange is discharged from the drain groove arranged outside the drain device; In addition, when the hot air outside contacts the condensed water on the surface of the sponge 2 and is cooled, a part of the condensed water will evaporate into water vapor when heated, and then enter the driver cabin, so that the humidity in the driver cabin is increased, and the dryness in the driver cabin is avoided. The comfort of the human body is affected.

[0056] As Figures 7 to 10 shown, the air conditioner provided by the application comprises a chassis 100 and an evaporator assembly 200 arranged on the chassis 100, the evaporator assembly 200 comprises a drain hole 201; a drain device 300, the drain device 300 is the above-mentioned drain device, the drain device 300 is installed on the chassis 100, and the drain device 300 is located at a position close to the drain hole 201 and the shell inlet 12 is communicated with the drain hole 201.

[0057] As Figure 9 shown, the evaporator assembly 200 comprises an evaporator foam 202, the evaporator foam 202 is provided with an evaporator drain groove 204 communicated with the drain hole 201, and the drain device 300 is tightly connected with the chassis 100 and the evaporator foam 202 of the evaporator assembly 200 to ensure the sealing property; when the air conditioner is running, the condensed water generated by the evaporator assembly 200 flows into the drain device 300 through the evaporator drain groove 204 and the drain hole 201 in turn, and is finally discharged to the outside of the air conditioner.

[0058] As Figure 10 shown, the air conditioner further comprises a fan 400, the fan 400 comprises a fan air outlet 401 and a fan air inlet 402, and the evaporator assembly 200 is arranged close to the fan air inlet 402 to exchange heat with the airflow before entering the fan air inlet 402; due to the driving of the fan 400, there is a negative pressure lower than the outside atmospheric pressure in the entire cavity of the evaporating cavity 203 of the evaporator assembly 200, and the air is exchanged with the evaporator assembly 200 in the process from the air inlet of the air conditioner to the air outlet of the air conditioner under the driving of the negative pressure.

[0059] The drainage device of the present application drives the rotation of the vane assembly 3 by the difference of the torque applied to different vane parts 31 of the vane assembly 3 by the pressure difference, to drive the condensed water in the containing cavity 11 to move to the sponge 2, so that the condensed water on the sponge 2 can fully exchange heat with the hot air outside, to improve the energy efficiency of the air conditioner, and without additional power device and power supply to drive the vane assembly 3 to move, to reduce the energy consumption of the air conditioner.

[0060] Compared with the drainage hole of the evaporator assembly of the air conditioner in the prior art directly communicating with the outside, the drainage device of the present application can also increase the resistance of the outside air directly entering the evaporating cavity 203, to reduce the pressure loss in the evaporating cavity 203, to facilitate the driving of the airflow in the evaporating cavity 203, to make the heat exchange effect of the evaporator assembly 200 more sufficient, to effectively improve the refrigerating capacity of the air conditioner, and to smoothly drain water and increase the air humidity entering the cockpit, to improve the comfort of the human body of the user in the cockpit.

[0061] The present application also provides a vehicle comprising the above-mentioned air conditioner.

[0062] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

In this way, the drainage device of the present application is installed on the bottom plate 100 of the air conditioner and connected with the drainage hole of the evaporator assembly 200 of the air conditioner, so as to drive the vane assembly 3 to rotate by the pressure difference between the gas pressure inside the evaporating cavity 203 of the evaporator assembly 200 and the air pressure outside, so as to make the condensed water discharged from the drainage hole and the hot air outside uniformly exchange heat at the sponge 2, so as to pre-cool the hot air outside entering the inside of the evaporating cavity 203, and the cooled air flows into the cabin of the air conditioner with the air conditioner through the air outlet of the air conditioner after passing through the evaporator assembly 200, thereby avoiding the problem of the decline of the refrigeration capacity of the evaporator assembly caused by the hot air outside being directly sucked into the evaporating cavity due to the drainage hole of the evaporating cavity 203 of the evaporator assembly directly communicating with the outside, solving the problem of the weakened heat exchange capacity of the internal circulation caused by the pressure loss of the evaporating cavity 203 of the evaporator assembly, solving the problem of the poor refrigeration capacity of the air conditioner in the prior art caused by the limitation of the battery on the vehicle, and being capable of increasing the humidity of the cooled air, solving the problem of the decline of the human comfort caused by the dry air in the cabin, improving the energy efficiency of the air conditioner, and reducing the energy loss of the air conditioner.
