[0005] In the above technical solution, the first flow guide ribs and the second flow guide ribs arranged on the water pan can support the indoor heat exchanger, so as to form a water storage gap between the indoor heat exchanger and the bottom wall of the water pan. At the same time, the first flow guide ribs and the second flow guide ribs are respectively curved towards directions away from each other, so as to guide the generated condensate water to flow uniformly to the first drain hole to avoid the condensate water from being concentrated. Further, the uniformly flowing condensate water can be guided to the outdoor heat exchanger through the first drain hole and evaporated into a gas phase by using the heat of the outdoor heat exchanger.

[0006] In the optional embodiments of the above mobile air conditioner, the first flow guide ribs are arc-shaped or zigzag curved; and / or the second flow guide ribs are arc-shaped or zigzag curved.

[0020] In the optional embodiment of the mobile air conditioner, one end of the flow guide section connected with the second drainage hole is provided with a water receiving groove which is recessed towards the outdoor heat exchange cavity.

[0021] In this way, the water receiving groove is arranged at the end of the flow guide section connected with the second drainage hole, so that the uniformity of the water flow of the second drainage hole can be ensured, the water flow is more stable, and the impact on the drainage pipe is reduced.

[0078] In combination Figures 1 to 8 As shown, the present application provides a mobile air conditioner, which comprises a shell 100, a partition plate 200, a first flow guide rib 310, a second flow guide rib 320, a first drain hole 410 and a second drain hole 420.

[0079] The inner part of the shell 100 is formed with a cavity. The partition plate 200 is arranged in the cavity and divides the cavity into the indoor heat exchange cavity 110 and the outdoor heat exchange cavity 120 distributed in upper and lower positions. The partition plate 200 is formed with a water collecting tray 210. The outdoor heat exchanger 510 is arranged in the outdoor heat exchange cavity 120. The first flow guide ribs 310 and the second flow guide ribs 320 arranged oppositely are arranged in the water collecting tray 210 along the width direction of the partition plate 200 at intervals. The first flow guide ribs 310 and the second flow guide ribs 320 are arranged to carry the indoor heat exchanger 520 and are bent towards directions away from each other respectively. The first drain hole 410 is arranged on the bottom wall of the water collecting tray 210 corresponding to the outdoor heat exchanger 510. The first drain hole 410 is arranged close to the first flow guide rib 310 or the second flow guide rib 320 and is arranged to communicate the indoor heat exchange cavity 110 and the outdoor heat exchange cavity 120. The second drain hole 420 is arranged on the side wall of the water collecting tray 210 and is arranged to be able to connect a drain pipe.

[0080] Optionally, the partition plate 200 is arranged in the cavity of the shell 100 and divides the cavity of the shell 100 into the indoor heat exchange cavity 110 and the outdoor heat exchange cavity 120 distributed in upper and lower positions. The upper surface of the partition plate 200 is arranged with the indoor heat exchanger 520 and the indoor fan. The peripheral edge of the partition plate 200 extends upwards with a side wall which abuts against the inner side wall of the shell 100 so that the partition plate 200 can also carry the indoor heat exchanger 520 and the indoor fan. The partition plate 200 can also carry the condensed water. Correspondingly, the shell 100 is arranged with the indoor air inlet 101 and the indoor air outlet corresponding to the indoor heat exchange cavity 110. The indoor heat exchanger 520 and the indoor fan are arranged in sequence between the indoor air inlet 101 and the indoor air outlet along the flow direction of the airflow. Optionally, the shell 100 comprises the front shell 130 and the rear shell 140. The indoor air inlet 101 is arranged on the rear shell 130.

[0081] Further, the outdoor heat exchanger 510, the outdoor fan and the compressor are arranged in the outdoor heat exchange cavity 120 below the partition plate 200. The shell 100 is arranged with the outdoor air inlet and the outdoor air outlet corresponding to the outdoor heat exchange cavity 120. The compressor, the outdoor heat exchanger 510 and the outdoor fan are arranged in sequence between the outdoor air inlet and the outdoor air outlet along the flow direction of the airflow.

[0082] Optionally, the partition plate 200 is formed with the water collecting tray 210 which is arranged to collect the condensed water generated by the indoor heat exchanger 520. The water collecting tray 210 is arranged with the first flow guide rib 310 and the second flow guide rib 320 arranged oppositely to carry the indoor heat exchanger 520. In this way, the bottom of the indoor heat exchanger 520 and the water collecting tray 210 form a space for the condensed water to flow.

[0083] Optionally, the direction from the front side wall to the back side wall of the shell 100 is the thickness direction of the shell 100, which is the width direction of the partition plate 200; the direction from the left side wall to the right side wall of the shell 100 is the width direction of the shell 100, which is the length direction of the partition plate 200. The outdoor heat exchanger 510 is arranged along the length direction of the partition plate 200.

[0084] Further, the first flow guide rib 310 and the second flow guide rib 320 are respectively curved towards directions away from each other. The curved first flow guide rib 310 and the second flow guide rib 320 can change the flow direction of the condensed water, reduce the flow rate, and the condensed water can form a uniform flow between them.

[0085] When the mobile air conditioner is cooling, the condensed water forming a uniform flow between the first flow guide rib 310 and the second flow guide rib 320 flows to the rest of the water pan 210 through the gaps between adjacent first flow guide ribs 310, the gaps between adjacent second flow guide ribs 320, and the gaps between the first flow guide rib 310 and the second flow guide rib 320, and mixes with the rest of the condensed water. The first drain hole 410 is arranged on the bottom wall of the water pan 210. In the case of gradually increasing condensed water, the condensed water flows on the bottom wall of the water pan 210, flows to the first drain hole 410, and can flow downward through the first drain hole 410, and then flow to the outdoor heat exchanger 510 corresponding to the drain hole 410, evaporate into a gas phase by using the heat of the outdoor heat exchanger 510; and / or, the condensed water can also be discharged through the second drain hole 420 and the drain pipe, so as to avoid the accumulation of the condensed water.

[0086] Optionally, in combination with the drawings shown in Figure 3 , 6 , the partition plate 200 further forms a mounting portion of the indoor fan and a fan water pan 220. The bottom of the fan water pan 220 is provided with a water inlet hole 221 corresponding to the outdoor heat exchanger 510, so as to make the part of the condensed water flow into the outdoor heat exchanger 510 through the water inlet hole 221 in the case of condensed water on the indoor fan.

[0087] Optionally, the second drain hole 420 is provided with a screw cap 421, which can be connected with the second drain hole 420 by rotating the screw cap.

[0088] In the above technical scheme, the first flow guide rib 310 and the second flow guide rib 320 arranged on the water pan 210 can support the indoor heat exchanger 520, so as to form a water containing gap between the indoor heat exchanger 520 and the bottom wall of the water pan 210. Meanwhile, the first flow guide rib 310 and the second flow guide rib 320 are respectively curved towards directions away from each other, so as to guide the condensed water to flow uniformly to the first drain hole 410. Further, the condensed water flowing uniformly through the first drain hole 410 can be guided to the outdoor heat exchanger 510, and evaporated into gas phase by the heat of the outdoor heat exchanger 510.

[0089] In the alternative embodiment of the mobile air conditioner, the first flow guide rib 310 is arc-shaped or fold line curved; and / or, the second flow guide rib 320 is arc-shaped or fold line curved.

[0090] Optionally, the first flow guide rib 310 is arc-shaped curved, so that the first flow guide rib 310 is not angular after being curved, and can better guide the condensed water, and is more convenient to clean; and / or, the second flow guide rib 320 is arc-shaped curved, so that the second flow guide rib 320 is not angular after being curved, and can better guide the condensed water, and is more convenient to clean.

[0091] Optionally, the first flow guide rib 310 is fold line curved; and / or, the second flow guide rib 320 is fold line curved. In this way, the processing can be facilitated, and the complexity can be reduced.

[0092] Optionally, the bending angle of the first flow guide rib 310 is greater than 100° and less than 160°. Preferably, the bending angle of the first flow guide rib 310 is 135°.

[0093] Optionally, the bending angle of the second flow guide rib 320 is greater than 100° and less than 160°. Preferably, the bending angle of the second flow guide rib 320 is 135°.

[0094] In the alternative embodiment of the mobile air conditioner, the plurality of first flow guide ribs 310 are arranged along the length direction of the partition plate 200, and the plurality of second flow guide ribs 320 are arranged along the length direction of the partition plate 200.

[0095] Alternatively, the plurality of first flow guide ribs 310 are arranged along the width direction of the partition plate 200, and the plurality of second flow guide ribs 320 are arranged along the width direction of the partition plate 200.

[0096] Alternatively, the first flow guide rib 310 is arranged obliquely relative to the length direction of the partition plate 200, and the second flow guide rib 320 is arranged obliquely relative to the length direction of the partition plate 200.

[0097] In this way, the first guide fins 310 and the second guide fins 320 can play a role of combing and distributing the water flow.

[0098] In the alternative embodiment of the mobile air conditioner, the first guide fins 310 and the second guide fins 320 are arranged in a staggered manner.

[0099] That is, the interval between adjacent first guide fins 310 is arranged opposite to the second guide fins 320, and the interval between adjacent second guide fins 320 is arranged opposite to the first guide fins 310. In this way, by arranging in a staggered manner, the gap between adjacent first guide fins 310 and the gap between adjacent second guide fins 320 can be arranged in a staggered manner, so that the condensed water can flow to other areas through different positions, thereby avoiding aggregation.

[0100] Alternatively, the first guide fins 310 and the second guide fins 320 are arranged in a corresponding manner. That is, the interval between adjacent first guide fins 310 is arranged opposite to the interval between adjacent second guide fins 320.

[0101] In the alternative embodiment of the mobile air conditioner, an annular protrusion 411 extending upward is formed around the periphery of the first drain hole 410.

[0102] In this way, by forming the annular protrusion 411, the condensed water can be prevented from flowing directly out of the first drain hole 410 when the second drain hole 420 is connected to the drain pipe, thereby ensuring the water flow when the condensed water is discharged from the first drain hole.

[0103] Alternatively, the height of the annular protrusion 411 is equal to or higher than the distance between the bottom of the second drain hole 420 and the bottom wall of the water pan 210, so that when the second drain hole 420 is opened and connected to the drain pipe, the condensed water is preferentially discharged from the second drain hole 420.

[0104] Alternatively, the annular protrusion 411 is not provided, so that the condensed water generated can directly flow to the first drain hole 410.

[0105] In the alternative embodiment of the mobile air conditioner, the mobile air conditioner further comprises a partition fin 330. The partition fin 330 extends along the length direction of the partition plate 200 to the water pan 210, and the water pan 210 is at least divided into a first water receiving area and a second water receiving area, wherein the partition fin 330 is provided with a gap 331; the first drain hole 410 is arranged in the first water receiving area, and the first guide fins 310 and the second guide fins 320 are arranged in the second water receiving area.

[0106] Thus, by arranging the partitioning ribs 330, the water pan 210 can be at least divided into the first water receiving area and the second water receiving area which are in communication with each other, thereby increasing the flow path for the condensed water and improving the flowability of the water; and the first drain hole 410 and the first and second flow guide ribs 310 and 320 are arranged in different water receiving areas, so that the condensed water can flow out through the first drain hole 410 after being uniformly flowed.

[0107] Optionally, the partitioning ribs 300 extend along the length direction of the indoor heat exchanger 520.

[0108] Optionally, the height of the partitioning ribs 330 is consistent with the height of the first and second flow guide ribs 310 and 320, so as to support the indoor heat exchanger 520.

[0109] Optionally, after the condensed water forms a uniform and stable flow in the second water receiving area, the condensed water flows into the first water receiving area through the gap 311, mixes with the condensed water in the first water receiving area, and then flows out through the first and / or second drain holes 410 and 420.

[0110] Alternatively, the partitioning ribs 300 can also extend along the width direction of the indoor heat exchanger 520.

[0111] Alternatively, the partitioning ribs 300 are not arranged, and only the first and second flow guide ribs 310 and 320 support the indoor heat exchanger 520 and guide the condensed water.

[0112] In the optional embodiments of the mobile air conditioner described above, the first water receiving area is arranged corresponding to the air inlet side of the indoor heat exchanger 520.

[0113] When the mobile air conditioner is in cooling, the indoor heat exchanger 520 acts as an evaporator, and more condensed water is generated on the air inlet side. In this way, the condensed water in the first water receiving area can be prevented from flowing to other areas, and can be quickly drained through the first or second drain hole 410 or 420.

[0114] Optionally, the partitioning ribs 330 are arranged in at least two, and the water pan 210 is divided into the first water receiving area, the second water receiving area and the third water receiving area. The first water receiving area is arranged corresponding to the air inlet side of the indoor heat exchanger 520, the third water receiving area is arranged corresponding to the air outlet side of the indoor heat exchanger 520, and the second water receiving area is arranged corresponding to the middle part of the indoor heat exchanger 520.

[0115] The condensed water in the third water receiving area flows to the second water receiving area and is gathered, and under the action of the first and second flow guide ribs 310 and 320, forms a uniform water flow, and then flows to the first water receiving area, thereby realizing the drainage of the condensed water.

[0116] In the alternative embodiment of the mobile air conditioner, the mobile air conditioner further comprises a second drain hole 420 arranged on the side wall of the water pan 210 and configured to be connected to a drain pipe.

[0117] The condensed water can be discharged through the second drain hole 420 and the drain pipe, so that the accumulation of the condensed water can be avoided.

[0118] In the alternative embodiment of the mobile air conditioner, the mobile air conditioner further comprises a second drain hole 420 arranged on the side wall of the water pan 210 and configured to be connected to a drain pipe.
