Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a vertical air conditioner indoor unit. BACKGROUND

[0002] The vertical air conditioner indoor unit comprises a main body, the main body comprises a first cavity arranged in the main body and a shell, the shell is provided with a heat exchange air inlet and a heat exchange air outlet, wherein the heat exchange air inlet and the heat exchange air outlet are communicated with the first cavity. The main body further comprises an indoor heat exchanger and a heat exchange fan, the indoor heat exchanger and the heat exchange fan are arranged in the first cavity, and the heat exchange fan is arranged on the front side of the indoor heat exchanger. Under the driving of the heat exchange fan, indoor air enters the first cavity from the indoor air inlet, and the indoor air entering the first cavity exchanges heat with the indoor heat exchanger and then 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 on people. The air guide vanes can be arranged in the air duct, and the air guide vanes are connected through connecting rods. When the air conditioner is cooling, the air guide vanes swing upward to guide the air upward. When the air conditioner is heating, the air guide vanes swing downward to guide the air downward. The rotation of the air guide vanes can make the air not blow directly on people as much as possible.

[0004] In the existing design, when the angle of the air guide vane swinging upward reaches a certain value, the air guide connecting rod interferes with the air guide vane, so that the air guide vane cannot continue to swing upward, and the angle range of the air guide vane swinging upward is relatively small. When the swinging angle of the air guide vane is small, there is a certain gap between the adjacent two air guide vanes. Due to the existence of the gap, air leakage occurs between the two air guide vanes, which makes the air guide vane have poor direct blow prevention effect.

[0005] The placement position of the air guide vane is unreasonable. The placement position of the air guide vane is close to the heat exchange fan, which is easy to produce abnormal sound, and the gap between the front volute tongue and the air guide vane and the gap between the rear volute tongue and the air guide vane are easy to leak air. The leaked air is not blocked by the air guide vane and is not guided by the air guide vane, which makes the air guide vane have poor direct blow prevention effect and air guiding effect.

[0006] Therefore, the present application provides a vertical air conditioner indoor unit. SUMMARY

DETAILED DESCRIPTION

[0095] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0096] This application discloses a vertical air conditioner indoor unit, as described below. Figures 1-51 Describe the indoor unit of the floor-standing air conditioner.

[0097] The indoor unit of a floor-standing air conditioner is a component of an air conditioner, which also includes the outdoor unit.

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

[0099] The main body 100 has a top and a bottom, with the height of the main body extending from its top to its bottom. The main body 100 also has a width, with the width extending from one side to the other. The main body has a front and a rear side positioned opposite each other, with the side of the main body facing the user being the front side, and the distance from the front side to the rear side being the front-to-back direction. The height, width, and front-to-back directions of the main body are perpendicular to each other.

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

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

[0102] refer to Figures 1-4 The housing 1 has a heat exchange air inlet 141 and a heat exchange air outlet 1421, 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 on the rear side of the main body, and the heat exchange air outlet 1421 is located on the front side of the main body.

[0104] The indoor heat exchanger 21 is located in the first cavity 131 and is used to exchange heat with the indoor air entering the first cavity.

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

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

[0107] An air conditioner outdoor unit includes the outdoor unit casing, the outdoor heat exchanger, and the outdoor fan.

[0108] The outdoor unit casing has an outdoor housing space, in which the outdoor fan and outdoor heat exchanger are located.

[0109] The outdoor unit casing is equipped with an outdoor air inlet and an outdoor air outlet, both of which are connected to the outdoor enclosure. The outdoor air inlet is used to introduce outdoor air into the outdoor enclosure, and the outdoor air outlet is used to exhaust air from the outdoor enclosure to the outside.

[0110] The rotation of the outdoor fan causes outdoor air to enter the outdoor enclosure through the outdoor air inlet and exchange heat with the outdoor heat exchanger. After heat exchange, the outdoor air flows out of the outdoor enclosure through the outdoor air outlet.

[0111] An air conditioner also includes a compressor and a throttling device, wherein the throttling device is used to limit airflow. The compressor is located in the outdoor enclosure, and the throttling device is also located in the outdoor enclosure.

[0112] Air conditioners execute a refrigeration cycle using a compressor, condenser, throttling device, and evaporator. The refrigeration cycle involves a series of processes including compression, condensation, expansion, and evaporation, supplying refrigerant to the conditioned and heat-exchanged air.

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

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

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

[0116] The throttling device causes the high-temperature, high-pressure liquid refrigerant condensed in the condenser to expand into a low-pressure liquid refrigerant.

[0117] The evaporator evaporates the refrigerant that expands in the throttling device and returns the refrigerant gas, which is in a low-temperature and low-pressure state, to the compressor.

[0118] An evaporator achieves a cooling effect by exchanging heat with the material being cooled using the latent heat of refrigerant evaporation. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0119] In 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 heating mode. When the indoor heat exchanger is used as an evaporator, the air conditioner is used as a cooler in cooling mode.

[0120] In some embodiments of this application, reference is made to Figures 4-5 The main body 100 includes the air duct component 3.

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

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

[0123] The main body 100 also includes air guide blades 4, and there are several air guide blades 4 arranged along the height direction of the main body.

[0124] The air guide vane 4 is located inside the air duct 30, and the air guide vane is located on the front side of the heat exchange fan. The air guide vane is rotatably connected to the air duct assembly.

[0125] The main body also includes a guide rod 51, which is connected to multiple guide vanes. The movement of the guide rod drives the guide vanes to rotate.

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

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

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

[0129] In some embodiments of this application, reference is made to Figure 6 The main body also includes a drive motor 52 and a crank 53, wherein the drive motor is connected to the crank and 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 this application, the heat exchange volute includes a volute top plate 315, and a drive motor 52 is disposed on the volute top plate and located above the volute top plate.

[0132] The top plate of the volute is provided with a connecting rod through hole 3151 that penetrates the top plate of the volute, and the air guide connecting rod passes through the connecting rod through hole and connects to the crank.

[0133] In some embodiments of this application, reference is made to 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 blades can also be disposed in the air outlet frame air duct and are connected to the air outlet frame.

[0137] Currently, the air guiding blades connected to the same connecting rod are generally arranged parallel to each other. When the connecting rod moves, the air guiding blades 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 blades the same and the air guiding directions of the air guiding blades the same. When there is a region where the air blows directly at people at the lower part of the air outlet and anti-direct-blowing needs to be achieved, a large area of the air outlet needs to be blocked by the lower air guiding blades. Since the air guiding directions of the air guiding blades are the same, a relatively large area of the upper part of the air outlet will also be blocked by the air guiding blades, resulting in less air volume at the upper part of the air outlet and affecting the refrigeration capacity of the air conditioner; on the contrary, in order to ensure the air volume at the air outlet, the area blocked by the air guiding blades is set small. Since the air guiding directions of the air guiding blades are the same, this will make the anti-direct-blowing function at the lower part of the air outlet weak, and there will still be direct blowing at the lower part of the air outlet, resulting in a poor user experience; since the air guiding directions of the air guiding blades are the same, this will also make the air outlet direction relatively single.

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

[0139] The rotation axis of the first air guiding blade and the air duct assembly is Z1, and the rotation axis of the first air guiding blade 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 blade and the first air guiding blade are connected to the same air guiding connecting rod. The second air guiding blade is located below the first air guiding blade. The rotation axis of the second air guiding blade and the air duct assembly is Z3, and the rotation axis of the second air guiding blade 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 blade is not equal to the rotation angle of the first air guiding blade.

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

[0143] The air guiding blades are provided to include a first air guiding blade and a second air guiding blade, and the second distance L2 is set to be less than the first distance L1, so that when the air guiding link moves vertically or downward by a certain distance, the rotation angles of the first air guiding blade and the second air guiding blade are different, enabling asynchronous air guiding of the first air guiding blade and the second air guiding blade and providing multiple air guiding effects.

[0144] In some embodiments of the present application, referring to Figures 10-15 , the air guiding blade includes a first air guiding plate 41, and the first air guiding plate is rotatably connected to the air duct assembly. The rotation axes of the first air guiding blade and the second air guiding blade are horizontally arranged.

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

[0146] When the air guiding link moves upward or downward and the second air guiding blade rotates by α from the initial position, the first air guiding blade rotates by β from the initial position, where α ≤ 90° and α > β. Here, 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, where 1 < H2 < 3.

[0148] When the air guiding link is set to move upward or downward and the second air guiding blade rotates by α from the initial position, the first air guiding blade rotates by β from the initial position, where α ≤ 90° and α > β. When the air guiding link moves upward by a certain distance, the rotation angle of the second air guiding blade is greater than that of the first air guiding blade, and the second air guiding blade can prevent direct blowing, and the first air guiding blade blocks less wind, enabling lower part to prevent direct blowing and upper part to output normal air; and when the air guiding link moves downward by a certain distance, the rotation angle of the second air guiding blade is greater than that of the first air guiding blade, making the downward air guiding angle of the second air guiding blade larger. When the air conditioner is heating, the air guiding angle can be increased and the air guiding range can be enlarged.

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

[0150] Among them, when α1 is a value in the range of 70° - 90°, β1 can be a value in the range of 20° - 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 this application, during the rotation of the second guide vane, the distance between the highest point of the second guide vane at the highest position and the bottom of the main body in the vertical direction is any value between 1.1m and 1.3m, so that the second guide vane can block the air outlet area below 1.1m-1.3m, thereby avoiding direct airflow to children and adults after they have sat down.

[0153] In some embodiments of this application, the average distance between two adjacent first guide vanes is a first distance, and the average distance between two adjacent second guide vanes is a second distance, wherein the first distance is greater than the second distance; this can improve the air guiding effect of the second guide vanes.

[0154] Currently, the placement of the air guide vanes is unreasonable. The air guide vanes are placed too close to the heat exchange fan, which can easily cause abnormal noise. Furthermore, air leakage is likely to occur at the gaps between the front volute and the air guide vanes, as well as at the gaps between the rear volute and the air guide vanes. The leaked air is neither blocked nor guided by the air guide vanes, resulting in poor anti-direct-blow effect and air guiding effect of the air guide vanes.

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

[0156] refer to Figures 19-20 The front volute tongue includes an inner wall surface 3121 for enclosing the air duct forming the volute shell; the inner wall surface of the front volute tongue includes a tongue tip surface 31211, a transition surface 31212, and an air outlet surface 31213.

[0157] The rear end of the anterior cochlear tongue transition surface is connected to the front end of the anterior cochlear tongue tip surface, and the anterior cochlear tongue transition surface is located on the side of the anterior cochlear tongue tip surface away from the posterior cochlear tongue. The rear end of the anterior cochlear tongue air outlet surface is connected to the front end of the anterior cochlear tongue transition surface, and the anterior cochlear tongue air outlet surface is located on the side of the anterior cochlear tongue transition surface away from the posterior cochlear tongue.

[0158] The air guide vane is located on the side of the front volute tongue's air outlet surface near the rear volute tongue. The air guide vane is rotatably connected to the rear volute tongue, and the end of the air guide vane near the front volute tongue's air outlet surface is located in front of the front volute tongue's transition surface.

[0159] The front volute tongue is configured with a front volute tongue tip surface, a front volute tongue transition surface, a front volute tongue air outlet surface, and a guide vane located in front of the front volute tongue transition surface. This allows the guide vane to block the front volute tongue tip surface, thus obstructing the airflow along it. This changes the airflow path, reduces air velocity, minimizes air leakage between the guide vane and the front volute tongue, and prevents direct airflow onto people.

[0160] In some embodiments of this application, reference is made to Figure 20 The front volute exhaust surface is flat, and the length of the front volute transition surface in the direction perpendicular to the front volute exhaust surface is L5, where L5 is any value between 2mm and 6mm, so that the size of the front volute transition surface is neither too large nor too small, making it easy to process while avoiding excessive impact on the structure.

[0161] In some embodiments of this application, reference is made to Figure 21 The front volute tongue tip surface includes a front volute tongue tip contour line 312111 parallel to the horizontal plane, and the front volute tongue air outlet surface includes a front volute tongue air outlet contour line 312131 parallel to the horizontal plane. The front volute tongue tip contour line has a first tangent line Q1 located at its front end point. The first tangent line is parallel to the front volute tongue air outlet contour line. The distance between the projection of the first tangent line and the front volute tongue air outlet contour line on the same horizontal plane is L6, where L6 is any value between 2mm and 6mm, so that the size of the front volute tongue transition surface is not too large or too small, which is easy to process and avoids excessive impact on the structure.

[0162] In some embodiments of this application, reference is made to Figure 22 The front volute transition surface 31212 includes a front volute transition contour line 312121 parallel to the horizontal plane. The projection of the front volute transition contour line 312121 and the front volute air outlet contour line 312131 onto the same horizontal plane forms an obtuse angle α, so as to avoid the angle being too small and obstructing the airflow.

[0163] In some embodiments of this application, reference is made to Figure 20 The inner wall surface 3121 of the front volute also includes the front volute air inlet surface 31214 connected to the rear end of the front volute tip surface 31211.

[0164] In some embodiments of this application, reference is made to Figure 19 The rear volute tongue 313 includes an inner wall surface 3131 for enclosing the air duct forming the volute. The inner wall surface of the rear volute tongue includes an air inlet surface 31311, a transition surface 31312, and an air outlet surface 31313.

[0165] 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 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 vane is connected to the rear volute tongue air outlet surface, and the air guide vane is located in front of the rear volute tongue transition surface.

[0166] The rear volute tongue is designed with an air inlet surface, a transition surface, and an outlet surface, as well as guide vanes located in front of the transition surface. This design allows the guide vanes to partially block the air inlet surface. Furthermore, the transition surface and the connection between the guide vanes and the outlet surface facilitate the placement of the guide vanes close to the air inlet surface, reducing the distance between them and minimizing air leakage. The transition surface also alters the airflow path, reducing air velocity and preventing direct airflow onto people.

[0167] In some embodiments of this application, reference is made to Figure 23 The rear volute tongue's air outlet surface is flat, and the length of the rear volute tongue's transition surface in the direction perpendicular to the rear volute tongue's air outlet surface is L7, where L7 is any value between 2mm and 6mm. This ensures that the size of the rear volute tongue's transition surface is neither too large nor too small, making it easy to process while avoiding excessive impact on the structure.

[0168] refer to Figure 24 The rear volute inlet surface includes a rear volute inlet profile 313111 parallel to the horizontal plane, and the rear volute outlet surface includes a rear volute outlet profile 313131 parallel to the horizontal plane. The rear volute inlet profile has a second tangent Q2 located at its front end point. The second tangent is parallel to the rear volute outlet profile. The distance between the projections of the second tangent and the rear volute outlet profile on the same horizontal plane is L4, where L4 is any value between 2mm and 6mm. This ensures that the size of the rear volute transition surface is neither too large nor too small, making it easy to process while avoiding excessive impact on the structure.

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

[0170] In some embodiments of this application, reference is made to Figure 26 The main body also includes an air outlet frame 32, which 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 this application, reference is made to Figure 27The inner wall surface of the front volute also includes the front volute guide surface 31215 connected to the front end of the front volute air outlet.

[0172] The air outlet frame includes a first inner wall surface 3211 and a second inner wall surface 3212 located on its side and used to form an air outlet frame duct. The first inner wall surface is located on the front side of the inner wall surface of the front volute, the second inner wall surface is located on the front side of the inner wall surface of the rear volute, and the front end of the guide surface of the front volute is located on the rear end of the first inner wall surface of the air outlet frame near the second inner wall surface of the air outlet frame.

[0173] Currently, when the upward swing angle of the air guide blades reaches a certain value, the air guide linkage and the air guide blades interfere with each other, preventing the air guide blades from swinging upwards further, resulting in a small range of upward swing angles for the air guide blades. When the swing angle of the air guide blades 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 blades less effective at preventing direct airflow.

[0174] Therefore, in some embodiments of this application, reference is made to Figures 28-29 The air guide blade 4 includes a first air guide plate 41 and a first connecting plate 42.

[0175] The first air guide plate and the rear volute 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 rod.

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

[0178] The rotation axis of the guide vane and the guide rod is Z5; the rotation axis of the guide vane and the rear volute is Z6.

[0179] Define the plane M1 as the plane that passes through the rotation axis of the guide vanes and is parallel to the first guide surface.

[0180] Z5 and Z6 are parallel, and the angle between the perpendiculars of Z5 and Z6 and the projection of the perpendiculars in the first plane is an acute angle d. This can increase the upward swing angle of the guide vanes and improve the anti-direct-blow effect of the guide vanes.

[0181] Specifically, 10°≤d≤60°.

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

[0183] Among them, 0° <e≤20°。

[0184] The first air guide surface also includes a second side 4112 and a third side 4113 located on its outer edge. The second side and the third side are respectively connected to the 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 parallel or arranged at an acute angle f.

[0185] Among them, 0° <f≤10°。

[0186] The first air guide surface also includes a fourth side 4114 and a fifth side 4115 located on its outer edge. The fourth side is connected to the end of the second side away from the first side, and the fifth side is located on the side of the third side away from the first side and is opposite to the fourth side. The fifth side is parallel to the fourth side or at an acute angle g.

[0187] Among them, 0° <g≤10°。

[0188] The first air guide plate includes a first clearance notch 414 for avoiding the air guide link. The first clearance notch is located between the third side and the fifth side and passes through the first air guide plate. The first clearance notch can prevent the air guide link and the first air guide plate from interfering with each other.

[0189] The first and second air guide surfaces can be arranged in parallel. The extension direction of the first air guide plate can 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 thereon, wherein the first connecting surface may be disposed on the side of the second connecting surface away from the end of the volute tongue after the first air guide plate is connected.

[0191] The first connecting surface can be perpendicular to the second air guide surface, and the second connecting surface can be parallel to the first connecting surface.

[0192] The first air guide plate is provided with a connecting part, which is rotatably connected to the rear volute tongue. The first connecting plate is provided with a connecting part, which is rotatably connected to the air guide connecting rod.

[0193] In some embodiments of this application, reference is made to Figures 30-32 The second guide vane and the guide rod are rotatably connected. Specifically, the first connecting plate of the second guide vane is provided with a second connecting part 423, and the guide rod is provided with a third connecting part 511. The second connecting part and the third connecting part are rotatably connected.

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

[0195] Since the second limiting post is difficult to insert into the first placement hole, elongated holes communicating with the first placement hole are provided on both sides opposite to the first placement hole. This allows the air guide rod to deform when the second limiting post is inserted into the first placement hole. The deformation of the air guide rod can deform the first placement hole, allowing the second limiting post to pass through the first placement hole, facilitating the rotational connection between the second connecting part and the third connecting part.

[0196] A first connecting portion 424 is provided on the first connecting plate of the first guide vane, and a fourth connecting portion 512 is provided on the guide rod. The first connecting portion is connected to the fourth connecting portion. The fourth connecting portion 512 includes a second placement hole 5121, which is an elongated hole. The first connecting portion includes a first connecting post 4241 and a first limiting post 4242. The first connecting post is located in the second placement hole. When the first guide vane rotates, the first connecting post rotates and slides in the second placement hole. The first limiting post 4242 is inserted into and protrudes from the second placement hole, so that the first connecting post is located in the second limiting hole. The first limiting post and the guide rod limit each other, so that the first connecting post is limited on the guide rod.

[0197] Since the first limiting post is difficult to insert into the second placement hole, elongated holes communicating with the second placement hole are provided on both sides opposite to the second placement hole. This allows the air guide rod to deform when the first limiting post is inserted into the second placement hole. The deformation of the air guide rod can deform the second placement hole, allowing the first limiting post to pass through the second placement hole, which facilitates 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 air guide rod.

[0199] In some embodiments of this application, the air guide blade includes a first air guide blade and a second air guide blade. The second distance L2 is set to be less than the first distance L1, so that when the air guide link 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. Both the first air guide blade and the second air guide blade can prevent direct blowing and can guide the wind. Compared with the first air guide blade, the second air guide blade has a larger rotation angle, which makes the second air guide blade more effective at preventing direct blowing.

[0200] When the rotation of the second air guiding blade makes the first air guiding plate of the second air guiding blade vertically arranged or arranged at an acute angle with the vertical line, the first air guiding 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 guiding plates will decrease, making it difficult for air to pass through between the two first air guiding plates, and causing condensation on the second air guiding blade to occur easily.

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

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

[0203] Refer to Figure 36 , when the first air guiding plate of the second air guiding blade 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 with the height direction of the main body, so that the second through hole can play a certain guiding role in the condensed water, making the condensed water flow downward along the second through hole.

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

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

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

[0207] In some embodiments of the present application, refer to Figures 37-39The heat exchange volute includes a volute base plate 314 at its bottom. The volute base plate 314 includes a guide surface 3141, which is located at the top of the volute base plate and below the air guide vanes. When condensate is generated on the air guide vanes, the condensate will fall from the air guide vanes onto the heat exchange volute base plate. When a large amount of water accumulates on the heat exchange volute base plate, the water may flow forward on the heat exchange volute base plate, causing the water to flow to other areas without water collection. The water may leak directly onto other parts, which, if electrical components are present, will affect the normal operation of the electrical components. Therefore, the guide surface is set at an angle i to the horizontal plane, and the front end of the guide surface is higher than the rear end. A recess 3142 is provided on the bottom plate of the volute, located behind the guide surface, to collect water from it. The inclined design of the guide surface and the recess on the bottom plate of the volute allow condensate droplets from the guide blades to flow along the guide surface into the recess after falling onto the guide surface. The recess serves to collect the condensate flowing down the guide surface, preventing it from flowing onto other electrical components and affecting them. Specifically, i > 2°.

[0208] The heat exchange fan is located in the recess. In the height direction of the main body, the bottom wall of the recess is located below the guide surface. The bottom wall of the recess is provided with a drain outlet 3143, and the water collected in the recess can be discharged from the recess through the drain outlet.

[0209] The main body also includes a water receiving tray 61, which is located below the heat exchange volute and is used to receive water discharged from the recessed part through the drain outlet. The condensate in the recessed part is discharged into the water receiving tray through the drain outlet.

[0210] The bottom wall of the recess includes a first upper surface 31421 and a second upper surface 31422 located at its top. The first upper surface 31421 is set at an angle j with the horizontal plane. The second upper surface 31422 is connected to the lowest end of the first upper surface. The drain outlet is located at the intersection of the first and second upper surfaces to facilitate water drainage from the recess. The included angle j is an acute angle.

[0211] The second upper surface can be set parallel to or inclined 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 this application, reference is made to Figures 40-43 The air guide vanes also include a second air guide plate 43.

[0213] The second air guide plate 43 is located on the 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. The second air guide plate and the first air guide plate are staggered, so that the air guide blades can prevent direct blowing. In addition, when the air guide blades prevent direct blowing, the air can flow to the front side of the first air guide plate, so that there is also cold air on the front side of the first air guide plate, avoiding the formation of condensation on the first air guide plate. The cold air 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, thus preventing the formation of condensation on the second air guide plate.

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

[0215] The third air guide surface is located on the side of the second air guide surface that is away from the first air guide surface, and the third air guide surface and the second air guide surface are staggered.

[0216] The third and fourth air guide surfaces are parallel, and both are perpendicular to the first and second connecting surfaces.

[0217] The third air guide surface is parallel to the second air guide surface.

[0218] When the air guide blades are in the initial position, the first air guide plate and the second air guide plate are parallel to the horizontal plane. When the air guide blades are 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 air guide vane includes a second air guide plate, the first air guide plate may not have a first clearance notch to avoid the air guide link. Of course, the first air guide plate may have a first clearance notch to avoid the air guide link.

[0220] The second air guide plate includes a first plate 4301 and a second plate 4302, wherein the first plate is located on the side of the first connecting plate away from the first end of the first air guide surface, and the second plate is located on the side of the first connecting plate close to the first end of the first air guide surface.

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

[0222] The rotation axis of the guide vane is projected onto the first plate surface and is perpendicular to or at an acute angle k to the sixth side, where 0° <k≤20°。

[0223] The first panel also includes a seventh side 43112 and an eighth side 43113 located on its outer edge. 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 arranged opposite each other, either parallel or at an acute angle l. Where 0° <l≤10°。

[0224] The seventh and eighth sides are connected to the first connecting plate.

[0225] The third air guide surface includes a second plate surface 4312 disposed on the second plate. The second plate surface includes a ninth side 43121 disposed at the end away from the first connecting plate. The ninth side and the fifth side are coplanar, and the fourth side is parallel to the plane formed by the ninth side and the fifth side.

[0226] The second plate is provided with a second avoidance notch 43021 for avoiding the air guide rod, wherein the second avoidance notch penetrates through the second plate.

[0227] The second panel includes a tenth side 43122 that is positioned opposite the ninth side, and a second clearance notch is located at the tenth side.

[0228] In some embodiments of this application, the first air guide plate includes a first end and a second end disposed opposite to each other, the second end of the first air guide plate being the end of the first air guide plate near the front volute, and the first end of the first air guide plate being the end of the first air guide plate near the rear volute.

[0229] When the first air guide plate is set vertically, the vertical distance between the second end of the first air guide plate and the air outlet surface of the front volute is any value between 2mm and 4mm, which reduces air leakage between the air guide blades and the front volute and avoids direct airflow to people; the vertical distance between the first end of the first air guide plate and the air outlet surface of the rear volute is any value between 2mm and 6mm, which reduces the distance between the air guide blades and the air inlet surface of the rear volute and reduces air leakage between the air guide blades and the rear volute.

[0230] In some embodiments of this application, the air guide vanes include a first air guide plate, a first connecting plate, and a second air guide plate. The first air guide plate and the second air guide plate are staggered, and the angle d between the perpendiculars of Z5 and Z6 and the projection of the perpendiculars onto the first plane is an acute angle. (Refer to...) Figure 44 The maximum upward rotation angle of the air guide blades can reach 90 degrees, so that the first air guide plate and the second air guide plate are set vertically, and the first air guide plate and the second air guide plate are set one in front of the other, so that the rotation angle of the air guide blades is large and the air guide blades can achieve a kind of anti-direct blowing effect.

[0231] In some embodiments of this application, reference is made to Figures 45-46 The air guide vanes also include a reinforcing plate 44, which connects the first air guide plate and the second air guide plate.

[0232] The reinforcing plate includes a first reinforcing plate 441. The first reinforcing plate includes a first reinforcing plate body 4411 and a second reinforcing plate body 4412.
