Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to a vertical air conditioner indoor unit. Background Art

[0002] The vertical air conditioner indoor unit includes a main body. The main body includes a first cavity disposed inside the main body and a casing. The casing is provided with a heat exchange air inlet and a heat exchange air outlet. Among them, both the heat exchange air inlet and the heat exchange air outlet communicate with the first cavity. The main body further includes an indoor heat exchanger and a heat exchange fan. Both the indoor heat exchanger and the heat exchange fan are disposed inside the first cavity. The heat exchange fan is disposed on the front side of the indoor heat exchanger. Driven by the heat exchange fan, indoor air enters the first cavity from the indoor air inlet. After the indoor air entering the first cavity exchanges heat with the indoor heat exchanger, it flows out from the heat exchange air outlet.

[0003] The air outlet position of the vertical air conditioner indoor unit is relatively low and often blows directly at people. Guide vanes can be arranged in the air duct and connected by connecting rods. When the air conditioner is cooling, the guide vanes swing upward, so that the guide vanes guide the air upward. When the air conditioner is heating, the guide vanes swing downward, so that the guide vanes guide the air downward; the rotation of the guide vanes can be driven so that the air does not blow directly at people as much as possible.

[0004] In the existing design, when the upward swing angle of the guide vanes reaches a certain value, the guide link interferes with the guide vanes, making it impossible for the guide vanes to continue swinging upward, resulting in a small upward swing angle range of the guide vanes; when the swing angle of the guide vanes is small, there will be a certain gap between two adjacent guide vanes. Due to the existence of the gap, air leakage will occur between the two guide vanes, making the anti-direct-blowing effect of the guide vanes poor.

[0005] The placement position of the guide vanes is unreasonable. The guide vanes are placed relatively close to the heat exchange fan, which is likely to generate abnormal sounds, and air leakage is likely to occur at the gaps between the front volute tongue and the guide vanes and between the rear volute tongue and the guide vanes. The leaked air will not be blocked by the guide vanes and will not be guided by the guide vanes either, making the anti-direct-blowing function and the air guiding effect of the guide vanes poor.

[0006] Therefore, the present application proposes a vertical air conditioner indoor unit. Summary of the Invention

[0096] This application proposes a vertical air conditioner indoor unit, which is referred to below Figure 1-Figure 51 Describe the indoor unit of a vertical air conditioner.

[0097] The vertical air conditioner indoor unit is a component of the air conditioner, wherein the air conditioner also includes an air conditioner outdoor unit.

[0098] refer to Figure 1-Figure 4 The vertical air conditioner indoor unit includes a main body 100.

[0099] The main body 100 has a top and a bottom, and the height direction of the main body is from the top of the main body to the bottom of the main body. The main body 100 also has a width direction, and the width direction of the main body is from one side of the main body to the other side thereof. The main body has a front side and a rear side that are arranged opposite to each other, and the side of the main body facing the user is the front side of the main body, and the front side of the main body to the rear side of the main body is the front-back direction of the main body. The height direction, width direction and front-back direction of the main body are perpendicular to each other.

[0100] refer to Figure 1-Figure 4 The main body 100 includes at least a first cavity 131 located inside the main body.

[0101] refer to Figure 1-Figure 4 The main body 100 includes a casing 1, an indoor heat exchanger 21 and a heat exchange fan 22.

[0102] refer to Figure 1-Figure 4 A heat exchange air inlet 141 and a heat exchange air outlet 1421 are formed on the housing 1, wherein the heat exchange air inlet is connected to the first cavity, and the heat exchange air outlet is also connected to the first cavity.

[0103] The heat exchange air inlet 141 is located at the rear side of the main body, and the heat exchange air outlet 1421 is located at the front side of the main body.

[0104] The indoor heat exchanger 21 is disposed in the first chamber 131 , and is used for exchanging heat with the indoor air entering the first chamber.

[0105] The heat exchange fan 22 is disposed in the first cavity 131 . The heat exchange fan 22 is located in front of the indoor heat exchanger. The heat exchange fan 22 is used to provide power for the flow of indoor air.

[0106] The rotation of the heat exchange fan causes the indoor air to enter the first chamber from the heat exchange air inlet to exchange heat with the indoor heat exchanger, and the indoor air after heat exchange is discharged from the first chamber from the heat exchange air outlet.

[0107] The air conditioner outdoor unit includes an outdoor casing, an outdoor heat exchanger and an outdoor fan.

[0108] An outdoor housing is provided in the outdoor housing, wherein an outdoor fan and an outdoor heat exchanger are arranged in the outdoor housing space.

[0109] The outdoor housing is provided with an outdoor air inlet and an outdoor air outlet, wherein both the outdoor air inlet and the outdoor air outlet are connected to the outdoor accommodation space. The outdoor air inlet is used to introduce outdoor air into the outdoor accommodation space, and the outdoor air outlet is used to lead the air in the outdoor accommodation space to the outside of the outdoor accommodation space.

[0110] The rotation of the outdoor fan causes outdoor air to enter the outdoor accommodation space from the outdoor air inlet to exchange heat with the outdoor heat exchanger, and the outdoor air after heat exchange flows out of the outdoor accommodation space from the outdoor air outlet.

[0111] The air conditioner also includes a compressor and a throttling device, wherein the throttling device is used for throttling. The compressor is arranged in the outdoor accommodation space, and the throttling device is also arranged in the outdoor accommodation space.

[0112] The air conditioner performs the refrigeration cycle of the air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged.

[0113] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the refrigerant gas in a high-temperature and high-pressure state.

[0114] The exhausted refrigerant gas flows into the condenser.

[0115] The condenser condenses the compressed refrigerant into liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0116] The throttle device expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant.

[0117] The evaporator evaporates the refrigerant expanded in the throttling device and returns the refrigerant gas in a low temperature and low pressure state to the compressor.

[0118] The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0119] Of the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator. When the indoor heat exchanger is used as a condenser, the air conditioner is used as a heater in a heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in a cooling mode.

[0120] In some embodiments of the present application, reference Figure 4-Figure 5 The main body 100 includes an air duct assembly 3 .

[0121] A passing air duct 30 is formed in the air duct assembly 3 , and the passing air duct 30 is connected to the heat exchange air inlet 141 and the heat exchange air outlet 1421 .

[0122] The heat exchange fan 22 is disposed in the air passage 30, and the heat exchange fan 22 is located in front of the indoor heat exchanger.

[0123] The main body 100 further includes a plurality of wind guide blades 4 , and the plurality of wind guide blades 4 are arranged along the height direction of the main body.

[0124] The air guide blade 4 is arranged in the air passage 30, and the air guide blade is located at the front side of the heat exchange fan, and the air guide blade is rotatably connected to the air passage assembly.

[0125] The main body also includes an air guide connecting rod 51, which is connected to a plurality of air guide blades. The movement of the air guide connecting rod drives the air guide blades to rotate.

[0126] In some embodiments of the present application, the air duct assembly 3 includes a heat exchange volute 31, and the heat exchange volute 31 is disposed in the first cavity. The heat exchange volute 31 is disposed in front of the indoor heat exchanger.

[0127] A volute air duct 311 is formed in the heat exchange volute, wherein the air passage duct includes the volute air duct, and the volute air duct is located at the rear end of the air passage duct. The volute air duct is connected with the heat exchange air inlet and the heat exchange air outlet.

[0128] The fresh air fan is located in the volute air duct, and the air guide blades are located in the volute air duct, and the air guide blades are located at the front side of the heat exchange fan, and the air guide blades are rotatably connected to the heat exchange volute.

[0129] In some embodiments of the present application, reference Figure 6 The main body also includes a driving motor 52 and a crank 53, wherein the driving motor is connected to the crank, and the driving motor drives the crank to rotate.

[0130] The crank is connected to the air guide connecting rod. The rotation of the crank drives the air guide connecting rod to move, and the movement of the air guide connecting rod drives the air guide blades to rotate.

[0131] In some embodiments of the present application, the heat exchange volute includes a volute top plate 315, and the drive motor 52 is disposed on the volute top plate and is located above the volute top plate.

[0132] A connecting rod through hole 3151 penetrating the volute top plate is provided on the volute top plate, and the air guide connecting rod passes through the connecting rod through hole and is connected to the crank.

[0133] In some embodiments of the present application, reference Figure 7, the air duct assembly further includes an air outlet frame 32. Specifically, the air outlet frame is disposed in the first cavity, in front of the heat exchange volute, and within the housing.

[0134] The air outlet frame includes an air outlet frame air duct therein. The air passing duct includes the air outlet frame air duct 321, and the air outlet frame air duct is located in front of the volute air duct.

[0135] The air outlet frame air duct connects the volute air duct and the heat exchange air outlet.

[0136] Specifically, the air guiding vanes can also be disposed in the air outlet frame air duct and are connected to the air outlet frame.

[0137] Currently, the air guiding vanes connected to the same connecting rod are generally arranged parallel to each other. When the connecting rod moves, the air guiding vanes connected to the moving connecting rod always remain parallel to each other during the rotation process. This makes the rotation angles of the air guiding vanes the same and the air guiding directions of the air guiding vanes the same. When it is desired to prevent direct blowing in the area directly below the air outlet, a large area of the air outlet needs to be blocked by the lower air guiding vanes. Since the air guiding directions of the air guiding vanes are the same, a relatively large area of the upper part of the air outlet will also be blocked by the air guiding vanes, resulting in less air volume output from the upper part of the air outlet and affecting the cooling capacity of the air conditioner. On the contrary, in order to ensure the air volume output from the air outlet, the area blocked by the air guiding vanes is set small. Since the air guiding directions of the air guiding vanes are the same, this will make the anti-direct blowing function in the lower part of the air outlet weak, and there will still be direct blowing on the lower part of the air outlet, resulting in a poor user experience. Since the air guiding directions of the air guiding vanes are the same, this will also make the air outlet direction relatively single.

[0138] In some embodiments of the present application, referring to Figure 8-Figure 9 , the air guiding vanes include a first air guiding vane 401 and a second air guiding vane 402.

[0139] The rotation axis of the first air guiding vane and the air duct assembly is Z1, and the rotation axis of the first air guiding vane and the air guiding connecting rod is Z2. Z1 and Z2 are parallel, and the perpendicular distance between Z1 and Z2 is the first distance L1.

[0140] The second air guiding vane and the first air guiding vane are connected to the same air guiding connecting rod. The second air guiding vane is located below the first air guiding vane. The rotation axis of the second air guiding vane and the air duct assembly is Z3, and the rotation axis of the second air guiding vane and the air guiding connecting rod is Z4. Z3 and Z4 are parallel, and the perpendicular distance between Z3 and Z4 is the second distance L2.

[0141] Specifically, L2 < L1. In the vertical direction, when the air guiding connecting rod moves up or down a certain distance, the rotation angle of the second air guiding vane is not equal to the rotation angle of the first air guiding vane.

[0142] Specifically, the rotation axis of the first air guiding vane and the heat exchange volute is Z1, and the rotation axis of the second air guiding vane and the heat exchange volute is Z3.

[0143] The air guide blades include a first air guide blade and a second air guide blade, and the second distance L2 is set to be smaller than the first distance L1, so that when the air guide link moves a certain distance in the vertical direction or downward, the rotation angles of the first air guide blade and the second air guide blade are different, thereby realizing asynchronous air guiding of the first air guide blade and the second air guide blade, and providing a variety of air guiding effects.

[0144] In some embodiments of the present application, reference Figure 10-Figure 15 The wind guide blade comprises a first wind guide plate 41, and the first wind guide plate is rotatably connected to the air duct assembly. The rotation axes of the first wind guide blade and the second wind guide blade are arranged horizontally.

[0145] The air guide blade has an initial position. When the air guide blade is in the initial position, the first air guide plate of the first air guide blade is horizontally arranged, and the first air guide plate of the second air guide blade is horizontally arranged. When the air guide blade is in the initial position, the first air guide plate does not affect the air volume of the air outlet.

[0146] When the wind guide link moves upward or downward and the second wind guide blade rotates α from the initial position, the first wind guide blade rotates β from the initial position, α≤90°, and α>β, wherein L2sinα=L1sinβ, sinα is the sine value of angle α, and sinβ is the sine value of angle β.

[0147] Among them, L1 / L2=H2, among them, 1 <H2<3。

[0148] When the air guide link moves upward or downward and the second air guide blade rotates α from an initial position, the first air guide blade rotates β from an initial position, α≤90°, and α>β, so that when the air guide link moves upward for a certain distance, the rotation angle of the second air guide blade is greater than the rotation angle of the first air guide blade, the second air guide blade can prevent direct blowing, and the first air guide blade blocks less wind, so that the lower part can be prevented from direct blowing and the upper part can be normally exhausted; and when the air guide link moves downward for a certain distance, the rotation angle of the second air guide blade is greater than the rotation angle of the first air guide blade, so that the downward air guiding angle of the second air guide blade is larger, and the air guide angle can be increased when the air conditioner is heating, thereby increasing the air guiding range.

[0149] Specifically, when the wind guide link moves upward and the second wind guide blade rotates by α1 from the initial position, the first wind guide blade rotates by β1 from the initial position, α1≤90°, and α1>β1. When the wind guide link moves downward and the second wind guide blade rotates by α2 from the initial position, the first wind guide blade rotates by β2 from the initial position, α2≤80°, and α2>β2.

[0150] When α1 is a value between 70° and 90°, β1 can be a value between 20° and 40°.

[0151] When α2 is a value between 30° and 70°, β2 can be a value between 10° and 40°.

[0152] In some embodiments of the present application, during the rotation of the second air guide blade, in the vertical direction, the distance between the highest point reached by the second air guide blade at the highest point and the bottom end of the main body is any value between 1.1m-1.3m, so that the second air guide blade can block the air outlet area below 1.1m-1.3m, avoiding direct blowing on children and avoiding direct blowing on adults who are sitting down.

[0153] In some embodiments of the present application, the average spacing between two adjacent first air guide blades is a first spacing, the average spacing between two adjacent second air guide blades is a second spacing, and the first spacing is greater than the second spacing; the air guiding effect of the second air guide blades can be improved.

[0154] At present, there are unreasonable aspects in the placement of the air guide blades. The air guide blades are placed close to the heat exchange fan, which is prone to abnormal noise and makes it easy for air leakage to occur in the gap between the front volute tongue and the air guide blade and in the gap between the rear volute tongue and the air guide blade. The leaked air will not be blocked or guided by the air guide blades, which makes the air guide blades' anti-direct blowing function and air guiding effect poor.

[0155] In some embodiments of the present application, reference Figure 16-Figure 19 The heat exchange volute includes a front volute tongue 312 and a rear volute tongue 313, wherein the front volute tongue 312 is arranged on the side of the heat exchange volute, and the rear volute tongue 313 is arranged on the side of the heat exchange volute, and the rear volute tongue and the front volute tongue are located on opposite sides of the volute air duct.

The rear end of the front volute tongue air outlet surface is connected to the front end of the front volute tongue transition surface, and the front volute tongue air outlet surface is located on the side of the front volute tongue transition surface away from the rear volute tongue.

[0158] The air guide blade is located on a side of the front volute tongue air outlet surface close to the rear volute tongue, the air guide blade is rotatably connected to the rear volute tongue, and one end of the air guide blade close to the front volute tongue air outlet surface is located in front of the front volute tongue transition surface.

[0160] In some embodiments of the present application, reference Fig. 20 The air outlet surface of the front volute tongue is a plane, and the length of the front volute tongue transition surface in the direction perpendicular to the air outlet surface of the front volute tongue is L5, where L5 is any value between 2mm and 6mm, so that the size of the front volute tongue transition surface will not be too large or too small, and it is easy to process while avoiding excessive impact on the structure.

The front volute tongue transition contour line 312121 and the front volute tongue outlet contour line 312131 are projected at an obtuse angle a on the same horizontal plane to avoid obstruction to the air flow caused by too small an angle.

[0163] In some embodiments of the present application, reference Fig. 20 The front volute tongue inner wall surface 3121 also includes a front volute tongue air inlet surface 31214 connected to the rear end of the front volute tongue tip surface 31211.

[0165] Among them, the rear end of the rear volute tongue transition surface is connected to the front end of the rear volute tongue air inlet surface, and the rear volute tongue transition surface is located on the side of the front end of the rear volute tongue air inlet surface away from the front volute tongue; the rear end of the rear volute tongue air outlet surface is connected to the front end of the rear volute tongue transition surface; the air guide blade is connected to the rear volute tongue air outlet surface, and the air guide blade is located in front of the rear volute tongue transition surface.

[0166] The rear volute tongue is provided with a rear volute tongue including an air inlet surface, a transition surface and an air outlet surface of the rear volute tongue, and an air guide blade is located in front of the transition surface of the rear volute tongue, so that the air guide blade can partially cover the air inlet surface of the rear volute tongue in front of the air inlet surface of the rear volute tongue, and because of the provision of the transition surface of the rear volute tongue and the connection of the air guide blade with the air outlet surface of the rear volute tongue, it is convenient to provide an air guide plate of the air guide blade close to the air inlet surface of the rear volute tongue, so that the distance between the air guide blade and the air inlet surface of the rear volute tongue is reduced, and the air leakage between the air guide blade and the rear volute tongue is reduced, and the provision of the transition surface of the rear volute tongue can change the flow path, reduce the air flow rate, and avoid direct blowing on people.

[0167] In some embodiments of the present application, reference Fig.23 The air outlet surface of the rear volute tongue is a plane, and the length of the rear volute tongue transition surface in the direction perpendicular to the air outlet surface of the rear volute tongue is L7, where L7 is any value between 2mm and 6mm, so that the size of the rear volute tongue transition surface will not be too large or too small, which is easy to process while avoiding excessive impact on the structure.

[0168] refer to Fig.24 The rear volute tongue air inlet surface includes a rear volute tongue air inlet contour line 313111 parallel to the horizontal plane, the rear volute tongue air outlet surface includes a rear volute tongue air outlet contour line 313131 parallel to the horizontal plane, the rear volute tongue air inlet contour line has a second tangent line Q2 located at its front end point, the second tangent line is parallel to the rear volute tongue air outlet contour line, and the distance between the second tangent line and the rear volute tongue air outlet contour line projected on the same horizontal plane is L4, wherein L4 is any value between 2mm and 6mm, so that the size of the rear volute tongue transition surface will not be too large or too small, and it is easy to process while avoiding excessive impact on the structure.

[0169] In some embodiments of the present application, reference Fig.25 The rear volute tongue transition surface 31312 includes a rear volute tongue transition contour line 313121 parallel to the horizontal plane, and the rear volute tongue transition contour line 313121 and the rear volute tongue air outlet contour line 313131 are projected at an obtuse angle b on the same horizontal plane.

[0170] In some embodiments of the present application, reference is made to Fig.26 The main body also includes an air outlet frame 32, and the air outlet frame includes an air outlet frame duct 321 located therein, wherein the air outlet frame duct 321 connects the volute duct and the heat exchange air outlet.

[0171] In some embodiments of the present application, reference Fig. 27The inner wall surface of the front volute tongue also includes a front volute tongue guide surface 31215 connected to the front end of the front volute tongue air outlet surface.

[0172] The air outlet frame includes a first inner wall surface 3211 and a second inner wall surface 3212 of the air outlet frame, which are located on the side thereof and are used to enclose an air duct of the air outlet frame, wherein the first inner wall of the air outlet frame is arranged on the front side of the inner wall surface of the front volute tongue, the second inner wall surface of the air outlet frame is located on the front side of the inner wall surface of the rear volute tongue, and the front end of the front volute tongue guide surface is located on the side of the rear end of the first inner wall surface of the air outlet frame close to the second inner wall surface of the air outlet frame.

[0173] At present, when the upward swing angle of the air guide blade reaches a certain value, the air guide connecting rod interferes with the air guide blade, making it impossible for the air guide blade to continue to swing upward, resulting in a smaller upward swing angle range of the air guide blade; when the swing angle of the air guide blade is small, there will be a certain gap between two adjacent air guide blades. Due to the existence of the gap, air will leak between the two air guide blades, making the air guide blade less effective in preventing direct blowing.

[0174] Therefore, in some embodiments of the present application, reference Figure 28-Figure 29 The wind guide blade 4 includes a first wind guide plate 41 and a first connecting plate 42 .

[0175] Wherein, the first air guide plate and the rear volute tongue are rotatably connected.

[0176] The first connecting plate is connected to one side of the first air guide plate, and the first connecting plate is rotatably connected to the air guide connecting rod.

[0177] Specifically, the first wind guide plate includes a first wind guide surface 411 and a second wind guide surface 412 . The first wind guide surface 411 and the second wind guide surface 412 are arranged opposite to each other, and the first connecting plate is connected to the second wind guide surface.

[0180] Z5 is parallel to Z6, and the angle between the perpendicular line of Z5 and Z6 and the projection of the perpendicular line in the first plane is an acute angle d, which can increase the upward swinging angle of the air guide blade and improve the anti-direct blowing effect of the air guide blade.

[0181] Specifically, 10°≤d≤60°.

[0182] The first wind guide surface includes a first edge 4111 arranged on its outer edge, wherein the first wind guide surface has a first end and a second end arranged opposite to each other, the first end of the first wind guide surface is connected to the rear volute tongue, the first edge is arranged at the second end of the first wind guide surface, and the projection of the rotation axis of the wind guide blade on the first wind guide surface is perpendicular to the first edge or is arranged at an acute angle e.

[0183] Among them, 0° <e≤20°。

[0184] The first wind guiding surface also includes a second side 4112 and a third side 4113 arranged on its outer edge, wherein the second side and the third side are respectively connected to two ends of the first side, the second side and the third side are arranged opposite to each other, and the second side and the third side are arranged in parallel or at an acute angle f.

[0185] Among them, 0° <f≤10°。

[0187] Among them, 0° <g≤10°。

[0188] The first air guide plate includes a first avoidance gap 414 for avoiding the air guide rod. The first avoidance gap is located between the third side and the fifth side and passes through the first air guide plate. The first avoidance gap can avoid interference between the air guide rod and the first air guide plate.

[0189] The first wind guide surface and the second wind guide surface may be arranged in parallel. The extension direction of the first wind guide plate may be perpendicular to the extension direction of the first connecting plate.

[0190] The first connecting plate may include a first connecting surface 421 and a second connecting surface 422 disposed on both sides thereof, wherein the first connecting surface may be disposed on a side of the second connecting surface away from an end of the rear volute tongue connected to the first air guide plate.

[0191] The first connecting surface may be perpendicular to the second wind guiding surface, and the second connecting surface may be parallel to the first connecting surface.

[0192] A connecting portion is provided on the first air guide plate, and the connecting portion on the first air guide plate is rotatably connected to the rear volute tongue. A connecting portion is provided on the first connecting plate, and the connecting portion on the first connecting plate is rotatably connected to the air guide connecting rod.

[0193] In some embodiments of the present application, reference Figure 30-Figure 32 The second air guide blade and the air guide connecting rod are rotatably connected. Specifically, a second connecting portion 423 is provided on the first connecting plate of the second air guide blade, and a third connecting portion 511 is provided on the air guide connecting rod. The second connecting portion is rotatably connected to the third connecting portion.

[0194] Specifically, the third connecting part 511 includes a first placement hole 5111 that passes through the wind guide connecting rod, wherein the second connecting part includes a second connecting column 4231 and a second limiting column 4232, the second connecting column is located in the first placement hole and can rotate in the first placement hole, wherein the second limiting column 4232 is inserted into the first placement hole and passes through the first placement hole so that the second connecting column is located in the first limiting hole, and the first limiting column and the wind guide connecting rod limit each other so that the second connecting column is limited on the wind guide connecting rod.

[0195] Since the second limiting column is difficult to insert into the first placement hole, long holes connected to the first placement hole are provided on the two opposite sides of the first placement hole, so that the second limiting column can deform the air guide connecting rod when inserted into the first placement hole. The deformation of the air guide connecting rod can deform the first placement hole, so that the second limiting column can pass through the first placement hole, thereby facilitating the rotational connection between the second connecting part and the third connecting part.

[0196] A first connection part 424 is provided on the first connection plate of the first wind guide blade, a fourth connection part 512 is provided on the wind guide connecting rod, the first connection part is connected to the fourth connection part, the fourth connection part 512 includes a second placement hole 5121, the second placement hole is a long hole, the first connection part includes a first connection column 4241 and a first limiting column 4242, the first connection column is located in the second placement hole, when the first wind guide blade rotates, the first connection column rotates and slides in the second placement hole. Among them, the first limiting column 4242 is inserted into the second placement hole and passes through the second placement hole so that the first connection column is located in the second limiting hole, and the first limiting column and the wind guide connecting rod are limited to each other so that the first connection column is limited on the wind guide connecting rod.

[0197] Since the first limiting column is difficult to insert into the second placement hole, long holes connected to the second placement hole are provided on the opposite sides of the second placement hole, so that the first limiting column can deform the air guide connecting rod when inserted into the second placement hole. The deformation of the air guide connecting rod can deform the second placement hole, so that the first limiting column can pass through the second placement hole, thereby facilitating the connection between the first connecting part and the fourth connecting part.

[0198] The extension direction of the second placement hole is perpendicular to or at an angle to the extension direction of the wind guide connecting rod.

[0199] In some embodiments of the present application, the air guide blade includes a first air guide blade and a second air guide blade, and the second distance L2 is set to be smaller than the first distance L1, so that when the air guide connecting rod moves upward a certain distance, the rotation angle of the second air guide blade is greater than the rotation angle of the first air guide blade, and the first air guide blade and the second air guide blade can both prevent direct blowing and guide the wind. Compared with the first air guide blade, the second air guide blade has a larger rotation angle, so the second air guide blade can have a better effect in preventing direct blowing.

[0200] When the rotation of the second air guide vane causes the first air guide plate of the second air guide vane to be vertically arranged or arranged at an acute angle to the vertical line, the first air guide plate can block the wind blown from the heat exchange fan and play a role in preventing direct blowing. However, the gap between two adjacent first air guide plates will decrease, making it difficult for air to pass through between the two first air guide plates, and causing the second air guide vane to be prone to condensation.

[0201] Therefore, since the air guide vane includes the first air guide plate for guiding air, referring to Figure 33-Figure 35 , a second through hole 413 penetrating the first air guide plate is provided on the first air guide plate of the second air guide vane.

[0202] By providing the second through hole, when the first air guide plate is not horizontally arranged, air can pass through, making the air temperature difference on both sides of the first air guide plate relatively small, reducing the generation of condensation on the second air guide vane, avoiding water on the blown air, and improving the user experience.

[0203] Referring to Fig.36 , when the first air guide plate of the second air guide vane is not horizontally arranged, the projection of the length direction of the second through hole on the vertical plane is parallel or arranged at an acute angle h to the height direction of the main body, so that the second through hole can play a certain guiding role for the condensed water, and the condensed water flows down along the second through hole.

[0204] Among them, 0° < h < 45°, which can improve the guiding effect of the second through hole and enable the condensed water to flow down faster.

[0205] The minimum value of the width L3 of the second through hole is H1, where H1 is any value in the range of 1.5 mm - 3 mm.

[0206] The second through hole is a long strip hole, and the two ends of the long strip hole can be arcs.

[0207] In some embodiments of the present application, referring to Figure 37-Figure 39The heat exchange volute includes a volute bottom plate 314 disposed at the bottom thereof. The volute bottom plate 314 includes a guide surface 3141. The guide surface is located at the top of the volute bottom plate and below the air guide blades. When condensed water is generated on the air guide blades, the condensed water will fall from the air guide blades to the heat exchange volute bottom plate. When a lot of water accumulates on the heat exchange volute bottom plate, the water may flow forward on the heat exchange volute bottom plate, so that the water may flow to other areas without water receiving. The water will directly leak on other parts. If there are electrical components, it will affect the normal operation of the electrical components. Therefore, the guide surface is set at an angle i with the horizontal plane, and the front end of the guide surface is higher than the rear end of the guide surface, and the bottom plate of the volute is provided with a recessed portion 3142 located at the rear side of the guide surface and used to receive water on the guide surface; the guide surface is set to be inclined and the recessed portion is provided on the bottom plate of the volute, so that after the condensed water on the wind guide blades drops on the guide surface, it can flow along the guide surface into the recessed portion, and the recessed portion has the function of receiving the condensed water flowing down from the guide surface, which can prevent the condensed water from flowing to other electrical components and affecting other electrical components. Specifically, i>2°.

[0208] Among them, the heat exchange fan is arranged in the recessed part. In the height direction of the main body, the bottom wall of the recessed part is located below the guide surface. A drainage port 3143 is provided on the bottom wall of the recessed part. The water received by the recessed part can be discharged from the recessed part through the drainage port.

[0209] The main body further includes a water receiving pan 61, wherein the water receiving pan 61 is located below the heat exchange volute and is used to receive water discharged from the recessed portion through the drain port, and the condensed water in the recessed portion is discharged into the water receiving pan through the drain port.

[0210] The bottom wall of the recessed portion includes a first upper surface 31421 and a second upper surface 31422 located at the top thereof, the first upper surface 31421 is arranged at an angle j with the horizontal plane, the second upper surface 31422 is connected to the lowest end of the first upper surface, and the drain port is located at the intersection of the first upper surface and the second upper surface, which is conducive to water draining out of the recessed portion. Among them, the angle j is an acute angle.

[0211] The second upper surface may be arranged parallel to or inclined with respect to the horizontal plane, and the lowest end of the second upper surface is connected to the lowest end of the first upper surface.

[0212] In some embodiments of the present application, reference Figure 40-Figure 43 The wind guide blade also includes a second wind guide plate 43.

[0213] The second air guide plate 43 is arranged on a side of the second air guide surface away from the first air guide surface, the second air guide plate 43 is connected to the first connecting plate, and the second air guide plate and the first air guide plate are staggered so that the air guide blades can prevent direct blowing, and when the air guide blades are prevented from direct blowing, the air can flow to the front side of the first air guide plate, so that there is cold wind on the front side of the first air guide plate, thereby preventing condensation water from being generated on the first air guide plate, and the cold wind blown to the front side of the first air guide plate can flow to the front side of the second air guide plate through the gap between the first air guide plate and the second air guide plate, thereby preventing condensation water from being generated on the second air guide plate.

[0214] Specifically, the second wind guide plate includes a third wind guide surface 431 and a fourth wind guide surface 432 which are arranged opposite to each other, wherein the fourth wind guide surface is located on a side of the third wind guide surface away from the first wind guide plate, and the first connecting plate is located on a side of the fourth wind guide surface away from the third wind guide surface.

[0215] The third wind guiding surface is located on a side of the second wind guiding surface away from the first wind guiding surface, and the third wind guiding surface and the second wind guiding surface are staggered.

[0216] The third wind guiding surface is parallel to the fourth wind guiding surface, and both the third wind guiding surface and the fourth wind guiding surface are perpendicular to the first connecting surface and the second connecting surface.

[0217] The third wind guiding surface is parallel to the second wind guiding surface.

When the air guide blade is in the anti-direct blowing position, the first air guide plate and the second air guide plate are set at an angle to the horizontal plane, and the second air guide plate is located in front of the first air guide plate.

[0219] When the wind guide blade includes the second wind guide plate, the first avoidance gap for avoiding the wind guide connecting rod may not be provided on the first wind guide plate.

[0221] The third wind guiding surface includes a first plate surface 4311 disposed on the first plate, and the first plate surface includes a sixth side 43111 disposed on an outer edge thereof, wherein the sixth side is disposed at an end of the first plate surface away from the second plate.

[0222] The projection of the rotation axis of the wind guide blade on the first plate surface is perpendicular to the sixth side or is arranged at an acute angle k, wherein 0° <k≤20°。

[0223] The first board surface also includes a seventh side 43112 and an eighth side 43113 disposed at its outer edge, wherein the seventh side 43112 and the eighth side 43113 are respectively connected to the two ends of the sixth side, the seventh side 43112 and the eighth side 43113 are disposed opposite to each other, and the seventh side 43112 and the eighth side 43113 are disposed parallel to each other or at an acute angle l. <l≤10°。
