[0955] The heat exchange volute 25 includes a front volute tongue 251 and a rear volute tongue 252, and the rear end of the rear volute tongue 252 is located between the heat exchange fan 22 and the indoor heat exchanger 21. The front volute tongue 251 is arranged close to the heat exchange air outlet 1421 and is located inside the volute tongue air duct 253.

[0956] The vertical air conditioner indoor unit further includes a first air guide plate 51 and a second air guide plate 52 .

[0957] The first air guide plate 51 is rotatably connected to the housing 1 , and the first air guide plate 51 is rotatably connected to the housing 1 corresponding to the heat exchange air inlet 141 .

[0958] The second air guide plate 52 is rotatably connected to the housing 1. The second air guide plate 52 is rotatably connected to the housing 1 corresponding to the heat exchange air inlet 141. The first air guide plate 51 and the second air guide plate 52 are respectively located on opposite sides of the heat exchange air outlet. The first air guide plate 51 and the second air guide plate 52 are used to close or open the heat exchange air outlet 1421.

[0959] The first air guide plate 51 and the second air guide plate 52 are arranged in a double-door style.

[0960] When the first air guide plate 51 and the second air guide plate 52 close the heat exchange air outlet 1421, the first air guide plate 51 abuts against the second air guide plate 52. The side of the first air guide plate 51 abutting against the second air guide plate 52 is defined as a first abutting surface 5151, and the side of the second air guide plate 52 abutting against the first air guide plate 51 is defined as a second abutting surface 5251. The first abutting surface 5151 and the second abutting surface 5251 are overlapped and staggered in the front-to-back direction of the main body.

[0961] Since the first abutting surface 5151 and the second abutting surface 5251 are overlapped and staggered in the front-to-back direction of the main body, the second air guide plate 52 and the first air guide plate 51 are at least partially overlapped in the front-to-back direction of the main body. The overlapping arrangement prevents a black seam from forming at the joint of the first air guide plate 51 and the second air guide plate 52 on the front side of the housing 1, and the user cannot see the gap from the joint of the first air guide plate 51 and the second air guide plate 52 on the front side of the housing 1, and the user cannot see the internal structure of the housing 1 through the joint of the first air guide plate 51 and the second air guide plate 52 on the front side of the housing 1, thereby improving the aesthetic effect of the air conditioner indoor unit.

[0962] At the same time, the first abutment surface 5151 and the second abutment surface 5251 are overlapped and staggered in the front and rear directions of the main body, and the gap between the two air guide plates after docking cannot be seen on the front side of the air conditioner indoor unit. Even if the vertical straightness of the first air guide plate 51 and the second air guide plate 52 is not good, the gap cannot be seen from the front, thereby reducing the size requirements for product processing and manufacturing and saving product costs.

[0963] The first wind deflector 51 includes a first windward panel 514 and a first leeward panel 515. The first windward panel 514 is disposed on the windward side of the first wind deflector 51 relative to the first leeward panel 515. The first leeward panel 515 is disposed on the leeward side of the first wind deflector 51 relative to the first windward panel 514. The first windward panel 514 and the first leeward panel 515 are configured to be detachably connected to facilitate the processing of the first wind deflector 51.

[0964] The second wind deflector 52 includes a second windward panel 524 and a second leeward panel 525. The second windward panel 524 is arranged on the windward side of the first wind deflector 51 relative to the second leeward panel 525. The second leeward panel 525 is arranged on the leeward side of the second wind deflector 52 relative to the second windward panel 524. The second windward panel 524 and the second leeward panel 525 are arranged to be detachably connected to facilitate the processing of the second wind deflector 52.

[0965] The first abutting surface 5151 is disposed on the first leeward panel 515 , and the second abutting surface 5251 is disposed on the second leeward panel 525 . When the first air guide plate 51 and the second air guide plate 52 close the heat exchange air inlet 141 , the first leeward panel 515 and the second leeward panel 525 abut against each other.

[0966] The first abutting surface 5151 includes a first contour line 51511 perpendicular to the horizontal plane, and the first contour line 51511 is provided at the edge of the first abutting surface 5151 away from the heat exchange volute 25. The second abutting surface 5251 includes a second contour line 52511 perpendicular to the horizontal plane, and the second contour line 52511 is provided at the edge of the second abutting surface 5251 away from the heat exchange volute 25.

[0967] When the first air guide plate 51 and the second air guide plate 52 close the heat exchange air outlet 1421, the second air guide plate 52 presses the first air guide plate 51. The first contour line 51511 is located at the front side of the first abutting surface, and the second contour line 52511 is located at the front side of the second abutting surface. The first contour line 51511 is located at the front side of the second contour line 52511, so that in the front-to-back direction of the main body, the first contour line 51511 is protruded from the second contour line 52511 toward the front side of the housing 1, which can visually improve the flush effect of the first air guide plate 51 and the second air guide plate 52 in the left-right direction.

[0968] At the same time, the first contour line 51511 is arranged to protrude from the second contour line 52511 toward the front side of the casing 1, which can reduce the dimensional requirements for product processing and manufacturing when the vertical straightness of the first air guide plate 51 and the second air guide plate 52 is not good, saving product costs. Even if the straightness of the first air guide plate 51 and the second air guide plate 52 is poor, the user's naked eye cannot clearly recognize the straightness of the first air guide plate 51 and the second air guide plate 52.

[0969] When the first air guide plate and the second air guide plate close the heat exchange outlet, in the front-back direction of the main body, the distance range Y1 between the first contour line 51511 and the second contour line 52511 is 0.3-0.4 mm, which reduces the dimensional requirements for straightness of product processing and manufacturing. The distance between the first contour line 51511 and the second contour line 52511 is small, which can improve the visual effect that the user's naked eye cannot clearly identify the straightness of the first air guide plate 51 and the second air guide plate 52.

[0970] The first abutting surface 5151 may be configured as a curved surface, and the second abutting surface 5251 may be configured as a curved surface.

[0971] The first abutting surface 5151 and the second abutting surface 5251 abut against each other at the front side in the front-to-back direction of the casing 1, and a gap is provided between the first abutting surface 5151 and the second abutting surface 5251 at the rear side in the front-to-back direction of the casing 1, so as to avoid excessive constraint in the height direction of the main body, improve the visual effect of the first air guide plate 51 and the second air guide plate 52 closing the heat exchange outlet 1421, and avoid the generation of a gap on the front side of the casing 1 after docking.

[0972] The left side to the right side of the main body is the width direction of the main body, and a gap is provided between the first abutting surface 5151 and the second abutting surface 5251 on the rear side in the front-to-back direction of the casing 1. The distance range Y2 of the gap in the width direction of the main body is 0.2-2mm, so that the gap is small and can meet the requirement that when the first air guide plate 51 and the second air guide plate 52 close the heat exchange outlet 1421, the gap will not interfere with the abutment of the first air guide plate 51 and the second air guide plate 52, thereby improving the closing visual effect of the first air guide plate 51 and the second air guide plate 52 and avoiding the generation of a gap after docking.

[0973] A water storage recess 51512 is provided on at least one of the first abutting surface 5151 and the second abutting surface 5251 , and a plurality of water storage recesses 51512 are arranged in sequence in the height direction of the main body.

[0974] Driven by the heat exchange fan 22, the indoor air enters the first chamber 131 through the heat exchange air inlet 141 to exchange heat with the indoor heat exchanger 21. The indoor air after heat exchange is discharged from the first chamber 131 through the heat exchange air outlet 1421. When the air discharged from the first chamber 131 flows through the first air guide plate 51 and the second air guide plate 52, the air discharged from the first chamber 131 will encounter the indoor air with high temperature and humidity at the first abutting surface 5151 of the first air guide plate 51 and the second abutting surface 5251 of the second air guide plate 52.

[0975] After the air discharged from the first cavity 131 merges with the indoor air, condensed water will form on the first abutting surface 5151 of the first air guide plate 51 and the second abutting surface 5251 of the second air guide plate 52 due to the temperature difference. The condensed water formed therein may drip onto the indoor floor.

[0976] By providing the water storage recess 51512, condensed water formed at the first abutting surface 5151 of the first air guide plate 51 and the second abutting surface 5251 of the second air guide plate 52 will be stored in the water storage recess 51512 when flowing downward along the first abutting surface 5151 or the second abutting surface 5251, thereby preventing the condensed water from dripping onto the indoor floor.

[0977] The water storage recess 51512 provided on the first air guide plate 51 is recessed toward the interior of the first air guide plate 51 , and the water storage recess 51512 provided on the second air guide plate 52 is recessed toward the interior of the second air guide plate 52 .

[0978] Multiple water storage recesses 51512 may be arranged at intervals in the height direction of the main body, and interval spaces are provided between adjacent water storage recesses 51512. Arranging the water storage recesses 51512 at intervals may visually prevent users from noticing the arrangement of the water storage recesses 51512, thereby improving the visual aesthetic effect.

[0979] In other embodiments, the edges of adjacent water storage recesses 51512 may be connected in sequence, so that the arrangement of the water storage recesses 51512 is more consistent, improving the aesthetic effect. At the same time, the increase in the number of water storage recesses 51512 leads to a better water storage effect.

[0980] When the first air guide plate 51 and the second air guide plate 52 close the heat exchange air outlet 1421, the second abutting surface 5251 is located in front of the first abutting surface 5151. The first abutting surface 5151 and the second abutting surface 5251 at least partially overlap in projection in the front-rear direction.

[0981] Since the first abutting surface 5151 and the second abutting surface 5251 at least partially overlap in the projection in the front-to-back direction, the partial overlap means that no black seam will be generated at the joint between the first air guide plate 51 and the second air guide plate 52 on the front side of the casing 1, and the user cannot see the gap from the joint between the first air guide plate 51 and the second air guide plate 52 on the front side of the casing 1, and the user cannot see the internal structure of the casing 1 through the joint between the first air guide plate 51 and the second air guide plate 52 on the front side of the casing 1, thereby improving the aesthetic effect of the air conditioner indoor unit.

[0982] At the same time, the first abutment surface 5151 and the second abutment surface 5251 at least partially overlap in the projection in the front-to-back direction, and the gap between the two air guide plates after they are connected cannot be seen on the front side of the air-conditioning indoor unit. Even if the vertical straightness of the first air guide plate 51 and the second air guide plate 52 is not good, the gap cannot be seen from the front, thereby reducing the dimensional requirements for product processing and manufacturing and saving product costs.

[0983] The first air guide plate 51 includes a first air guide inner plate 511 , which is connected to a side of the first air guide plate 51 close to the heat exchange volute 25 , and a first ventilation hole 51111 is provided on the first air guide inner plate 511 .

[0984] The second air guide plate 52 includes a second air guide inner plate 521 . The second air guide inner plate 521 is connected to a side of the second air guide plate 52 close to the heat exchange volute 25 . A second ventilation hole 52111 is provided on the second air guide inner plate 521 .

[0985] When the first air guide plate 51 and the second air guide plate 52 open the heat exchange air outlet 1421, the first ventilation hole 51111 is extended from the side close to the heat exchange volute 25 to the direction away from the heat exchange volute 25 and away from the bottom of the casing 1. The second ventilation hole 52111 is extended from the side close to the heat exchange volute 25 to the direction away from the heat exchange volute 25 and away from the bottom of the casing 1.

[0986] Driven by the heat exchange fan 22, the indoor air enters the first chamber 131 through the heat exchange air inlet 141 to exchange heat with the indoor heat exchanger 21, and the indoor air after heat exchange flows out of the first chamber 131 through the heat exchange air outlet 1421. When the heat exchanged air flows through the first air guide inner plate 511 and the second air guide inner plate 521, it encounters indoor air with high temperature and humidity.

[0987] After the heat-exchanged air merges with the indoor air, condensed water will be formed at the first air guide inner plate 511 and the second air guide inner plate 521 due to the temperature difference. The condensed water formed therein has the problem of dripping into the inside of the housing 1.

[0988] When the first air guide plate 51 and the second air guide plate 52 rotate to open the heat exchange air outlet 1421 , the first air guide inner plate 511 rotates along with the first air guide plate 51 , and the second air guide inner plate 521 rotates along with the second air guide inner plate 521 .

[0989] By arranging a first ventilation hole 51111 on the first air guide inner plate 511, the first ventilation hole 51111 extends from a side close to the heat exchange volute 25 to a direction away from the heat exchange volute 25 and away from the bottom part of the casing 1, so that condensed water formed on the first air guide inner plate 511 can be drained toward the rear side of the casing 1 along the extension direction of the first ventilation hole 51111 to prevent the condensed water from dripping onto the ground outside the casing 1.

[0990] By arranging a second ventilation hole 52111 on the second air guide inner plate 521, the second ventilation hole 52111 extends from a side close to the heat exchange volute 25 to a direction away from the heat exchange volute 25 and away from the bottom of the casing 1, so that condensed water formed on the first air guide inner plate 511 can be drained toward the rear side of the casing 1 along the extension direction of the first ventilation hole 51111 to prevent the condensed water from dripping onto the ground outside the casing 1.

[0991] The first wind guide inner plate 511 includes a first windward inner plate 5111 and a first leeward inner plate 5112. When the first wind guide plate and the second wind guide plate open the heat exchange outlet, the first leeward inner plate is arranged away from the second wind guide plate relative to the first windward inner plate. When the first wind guide plate and the second wind guide plate open the heat exchange outlet, the first windward inner plate 5111 is located at the rear side of the first leeward inner plate 5112, a first spacing space is arranged between the first windward inner plate 5111 and the first leeward inner plate 5112, the first ventilation hole 51111 is arranged on the first windward inner plate 5111, and the first leeward inner plate 5112 is not arranged with an opening.

[0992] The air after heat exchange in the indoor heat exchanger 21 can flow through the first ventilation hole 51111 to pass through both sides of the first windward inner plate 5111, so that the temperature difference on both sides of the first windward inner plate 5111 is reduced, thereby reducing the formation of condensation water on the first windward inner plate 5111 and preventing condensation water from dripping into the casing 1.

[0993] The first windward inner plate 5111 and the first leeward inner plate 5112 are connected end to end in the height direction of the main body, and a first spacing space is enclosed between the first windward inner plate 5111 and the second windward inner plate 5211. The air after heat exchange by the indoor heat exchanger 21 can flow into the first spacing space through the first ventilation hole 51111, and then be guided by the first leeward inner plate 5112, which can weaken the wind force of the air discharged from the heat exchange outlet 1421 to prevent the air from blowing directly on the user.

[0994] The first connection plate 5113 is disposed in the first spacing space, and the first connection plate 5113 is integrally formed with the first windward inner plate 5111 and the first leeward inner plate 5112. The first connection plate 5113 is used to connect the first windward inner plate 5111 and the first leeward inner plate 5112 to strengthen the structural strength between the first windward inner plate 5111 and the first leeward inner plate 5112, so as to avoid the first wind guide inner plate 511 shaking and generating noise when the wind is discharged.

[0995] The second wind-guiding inner plate 521 includes a second windward inner plate 5211 and a second leeward inner plate 5212. The second windward inner plate 5211 is located at the rear side of the second leeward inner plate 5212. A second spacing space is provided between the second windward inner plate 5211 and the second leeward inner plate 5212. The second ventila...
