Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air outlet device and a vertical air conditioner. Background Art

[0002] Household air conditioners can be mainly divided into two types: wall-mounted air conditioners and floor-standing air conditioners. Existing floor-standing air conditioners have a single air outlet mode and cannot well meet the user's usage needs in multiple scenarios. Summary of the Invention

[0003] The first object of the present invention is to provide an air outlet device to solve the technical problem of the single air outlet mode of the existing vertical air conditioner.

[0004] The air outlet device provided by the present invention includes an air outlet frame, which has an upper air outlet and a lower air outlet, wherein the upper air outlet is rotatably installed with at least two air guide plates, and the at least two air guide plates are arranged along the left and right directions; the lower air outlet is rotatably installed with at least one rotating swing blade, and the rotation axes of the air guide plate and the rotating swing blade are both along the up and down directions; the rotating swing blade includes a plurality of swing blades spaced along the up and down directions and inclined in the same direction relative to the horizontal plane, and the plurality of swing blades are relatively fixedly arranged, and during the rotation of the rotating swing blade, the plurality of swing blades have an upward air guiding position, a downward air guiding position and a horizontal air supply position.

[0005] The use of this air outlet device in a floor-standing air conditioner is described as an example. By providing an air outlet frame with an upper air outlet and a lower air outlet, and disposing at least two air guide plates rotatable about a vertical axis at the upper air outlet, and at least one rotating pendulum blade rotatable about a vertical axis at the lower air outlet, the floor-standing air conditioner can be configured with different air outlet modes by controlling the rotation angles of the air guide plates and the rotating pendulum blades, thereby meeting user needs in various scenarios.

[0006] Among them, at the position of the upper air outlet, the air guide plate can change the outlet angle of the air-conditioning air blown out through the upper air outlet in the left and right directions during the rotation process; at the position of the lower air outlet, the rotating swing blade can make the swing blade have an upward air guiding position, a downward air guiding position and a horizontal air supply position during the rotation process, so as to change the outlet angle of the air-conditioning air blown out through the lower air outlet in the up and down directions.

[0007] Furthermore, the air outlet device has a far-throw and near-soft mode. In this far-throw and near-soft mode, the air guide plates of the upper air outlet are all in a forward air-directing position, and during cooling operation, the plurality of swinging blades of the rotating blades are in an upward air-directing position; and during heating operation, the plurality of swinging blades of the rotating blades are in a downward air-directing position. In this far-throw and near-soft mode, the upper air outlet performs a "far-throw" function, blowing the conditioned air farther away. For example, in larger indoor spaces such as living rooms and dining rooms, this mode allows the conditioned air to blow farther away, ensuring a uniform temperature throughout the space. Furthermore, the lower air outlet performs a "near-soft" function. During cooling operation, the conditioned air from the lower air outlet is blown upward, rather than directly, with a wind speed of less than 0.5 m / s at close range, resulting in a gentle wind speed. This can reduce the adverse effects of cold air on elderly and children, and reduce direct cold air when simultaneous cooling is required. During heating operation, the conditioned air from the lower air outlet is blown downward, closer to the ground.

[0008] And / or, the air outlet device has an ultra-long-distance airflow mode. In this ultra-long-distance airflow mode, the air guide plates of the upper air outlet are all in a forward airflow-guiding position, and the plurality of swinging blades of the rotating swing blade are all in a horizontal airflow-delivering position. This ultra-long-distance airflow mode of the air outlet device can achieve ultra-long-distance airflow delivery.

[0009] Furthermore, the upper air outlet is also rotatably mounted with a plurality of sweeping blades spaced vertically apart, with the rotational axes of the plurality of sweeping blades being in the left-right direction. In the ultra-long-range airflow mode, the plurality of sweeping blades are in a forward-blowing position; in the long-range, near-soft mode, the plurality of sweeping blades have an upward sweeping position for cooling operation and a downward sweeping position for heating operation. By providing the plurality of sweeping blades at the upper air outlet, the upward and downward swinging of the plurality of sweeping blades can be utilized to achieve upward and downward sweeping at the upper air outlet position, thereby increasing the number of air outlet modes at the upper air outlet. Specifically, in the ultra-long-range airflow mode, the sweeping blades can be in a forward-blowing position, adjusting the upper air outlet to the most favorable airflow position, so that the conditioned air from the upper air outlet can be blown as far as possible; in the long-range, near-soft mode, the conditioned air from the upper air outlet can be blown upward during cooling operation to avoid direct blowing, and can be blown downward during heating operation, with the hot air as close to the ground as possible, thereby improving the user experience.

[0010] Furthermore, the air outlet frame has an air outlet surface. When the air guide plate is in the forward air-discharging position, the air guide plate surface is perpendicular to the air outlet surface. When the swing blade is in the horizontal air-discharging position, the swing blade is perpendicular to the air outlet surface. This arrangement allows the air guide plate and swing blade to be adjusted to the most favorable air outlet position when the upper and lower air outlets need to be blown to a distant location, thereby reducing obstruction to the air outlet process and allowing the conditioned air to be blown as far as possible.

[0011] Furthermore, the air guide plate includes an outer plate and an inner plate that are parallel to each other, and a connecting plate connecting the outer plate and the inner plate. The outer plate is longer than the inner plate, and the outer plate is wider than the inner plate. By configuring the air guide plate in this manner, the conditioned air is not only more smoothly and centrally distributed during its discharge through the upper air outlet, but also gathers the conditioned air, allowing it to travel farther.

[0012] Furthermore, the air outlet device also has a wide-area air supply mode. In this wide-area air supply mode, the air outlet sides of the air guide plates located at the left and right ends of the upper air outlet are flared, the multiple swinging blades of at least one rotating swing blade are in an upward air-directing position, and the multiple swinging blades of at least one rotating swing blade are in a downward air-directing position. This configuration increases the distribution area of the conditioned air delivered through the upper air outlet in the left-right direction, and increases the distribution area of the conditioned air delivered through the lower air outlet in the vertical direction, thereby achieving wide-area air supply from the air outlet device in both the left-right and vertical directions. And / or, the air outlet device also has a centralized air supply mode. In this centralized air supply mode, the air outlet sides of the air guide plates located at the left and right ends of the upper air outlet are closed, and the multiple swinging blades of each rotating swing blade are perpendicular to the air outlet surface. This configuration allows the conditioned air delivered through the upper air outlet to be concentrated and delivered in the middle of the upper air outlet, and allows the conditioned air delivered through the lower air outlet to be delivered horizontally, thereby achieving centralized air supply to the room.

[0013] Furthermore, the number of the air guide plates is two. This arrangement not only meets the air supply requirements at the upper air outlet, but also reduces the cost of installing the air guide plates. And / or, the number of the rotating blades is two, and the two rotating blades are arranged in the left-right direction. This arrangement not only ensures that the rotating blades cover the lower air outlet, but also helps to reduce the size of the blades.

[0014] Furthermore, the rotating swing blades also include supporting ribs, which are fixedly connected to the plurality of swing blades, and the supporting ribs are connected to the edge portions of the swing blades; wherein the supporting ribs are provided with air guide surfaces, and in the top view of the structure in the horizontal air supply position, the air guide surfaces are at an angle to the air outlet surface, and / or the number of the supporting ribs is multiple, and the multiple supporting ribs are arranged at intervals along the circumference of the swing blades. On the one hand, this arrangement can achieve the relative fixation of the plurality of swing blades, and the connection structure is simple. On the other hand, it can also reduce obstruction to the air outlet process and reduce the attenuation of the air volume. Moreover, when horizontal air supply is performed, the air-conditioned air blown out through the air duct can be discharged along the air guide surface of the supporting ribs, and the air guide surface of the supporting ribs plays a certain guiding role for the air-conditioned air.

[0015] Furthermore, the outline of the swing blade includes a first straight edge, a first curved edge, a second straight edge, and a second curved edge, connected in sequence. The first straight edge is opposite the second straight edge, and the first curved edge is opposite the second curved edge. Both the first curved edge and the second curved edge are curved and convex away from the center of the swing blade. In the horizontal air supply position, the first straight edge and the second straight edge are arranged in a left-right direction. In the upward and downward air supply positions, the first curved edge and the second curved edge are arranged in a left-right direction. By configuring the swing blade with the above-described shape, the swing blade can, on the one hand, ensure a larger air flow area, and, on the other hand, ensure the aesthetics of the swing blade, enhancing the user's visual experience. Furthermore, this configuration reduces the left-right dimension of the swing blade when horizontal air is supplied from the lower air outlet, thereby reducing obstruction to the conditioned air. In both upward and downward air supply, the air inlet and outlet ends of the swing blade are straight edges, thereby ensuring greater consistency in the conditioned air as it leaves the swing blade.

[0016] A second object of the present invention is to provide a vertical air conditioner to solve the technical problem of the single air outlet mode of the existing vertical air conditioner.

[0017] The vertical air conditioner provided by the present invention comprises a body and the above-mentioned air outlet device, wherein the body and the air outlet frame are relatively fixedly arranged; and the at least two air guide plates are located in front of the multiple air sweeping blades of the air outlet device.

[0018] By arranging the above-mentioned air outlet device in the vertical air conditioner, the vertical air conditioner accordingly has all the advantages of the above-mentioned air outlet device, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Figure 1 A schematic diagram of the main structure of the vertical air conditioner provided in this embodiment in the ultra-long wind mode; Figure 2 for Figure 1 A magnified view of the local structure at point A; Figure 3 This is a schematic diagram of the main structure of the vertical air conditioner provided in this embodiment in the long-throw and short-throw soft mode and cooling operation; Figure 4 for Figure 3 A magnified view of the local structure at point B in the middle; Figure 5 A schematic diagram of the three-dimensional structure of a vertical air conditioner provided in this embodiment; Figure 6 for Figure 5 A magnified view of the local structure at C in the middle. Figures 1 to 6 As shown, this embodiment provides an air outlet device 020, including an air outlet frame 100, the air outlet frame 100 has an upper air outlet 110 and a lower air outlet 120, wherein the upper air outlet 110 is rotatably installed with two air guide plates 200, and the two air guide plates 200 are arranged along the left and right directions; the lower air outlet 120 is rotatably installed with two rotating pendulum blades 300, and the rotation axes of the air guide plates 200 and the rotating pendulum blades 300 are both along the up and down directions.

[0039] Figure 7 This is a schematic diagram of the three-dimensional structure of the rotating blade 300 of the air outlet device 020 provided in this embodiment. Figure 1 、 Figure 3 and Figure 5 , and combined with Figure 7In this embodiment, the rotating pendulum blade 300 includes a plurality of swing blades 310 spaced apart in the up and down directions and inclined in the same direction relative to the horizontal plane. The plurality of swing blades 310 are relatively fixedly arranged. During the rotation of the rotating pendulum blade 300, the plurality of swing blades 310 have an upward air guiding position, a downward air guiding position and a horizontal air supply position.

[0040] By setting an air outlet frame 100 with an upper air outlet 110 and a lower air outlet 120, and setting at least two air guide plates 200 that can rotate around a vertical axis at the upper air outlet 110, and setting at least one rotating pendulum blade 300 that can rotate around a vertical axis at the lower air outlet 120, the vertical air conditioner can have different air outlet modes when in use by controlling the rotation angle of the air guide plate 200 and the rotation angle of the rotating pendulum blade 300, thereby meeting the user's usage needs in multiple scenarios.

[0041] Among them, at the position of the upper air outlet 110, the air guide plate 200 can change the air outlet angle of the air-conditioning air blown out through the upper air outlet 110 in the left and right directions during the rotation process; at the position of the lower air outlet 120, the rotating swing blade 300 can make the swing blade 310 have an upward air guiding position, a downward air guiding position and a horizontal air supply position during the rotation process, so as to change the air outlet angle of the air-conditioning air blown out through the lower air outlet 120 in the up and down directions.

[0042] Figure 8 The schematic diagram of the main structure of the plurality of swing blades 310 of the rotating swing blade 300 of the air outlet device 020 provided in this embodiment is in the upward wind-guiding position. Figure 8 As shown, when the vertical air conditioner is operated in cooling mode, the rotating swing blades 300 can be rotated to the upward air guiding position. At this time, each swing blade 310 is tilted upward, so that the cold air blown out through the body 010 of the vertical air conditioner can be blown upward under the action of the swing blades 310, not only preventing people from being blown nearby, but also increasing the air supply distance.

[0043] Figure 9 This is a partial structural diagram of the multiple swing blades 310 of the rotating swing blade 300 of the air outlet device 020 provided in this embodiment in the downward wind-guiding position. Figure 9 As shown, when the vertical air conditioner is operated in the heating mode, the rotating swing blades 300 can be rotated to the downward air guide position. At this time, each swing blade 310 is tilted downward, so that the hot air blown out through the body 010 of the vertical air conditioner can be blown downward under the action of the swing blades 310, and the hot air is blown out closer to the ground.

[0044] When horizontal air flow is required, the rotating blade 300 is rotated to the horizontal air supply position. Figure 1At this time, the conditioned air blown out through the body 010 of the vertical air conditioner can be directly blown out through the air outlet gap formed between any two adjacent swing blades 310 to form horizontal air supply.

[0045] By providing two air deflectors 200, not only can the air supply requirements at the upper air outlet 110 be met, but the installation cost of the air deflectors 200 can also be reduced. Different air deflectors 200 can be driven by different drive mechanisms to achieve rotation of each air deflector 200 in different directions and angles, thereby enabling the air outlet device 020 to have multiple air outlet modes at the upper air outlet 110 to meet the needs of different users. Specifically, the drive mechanism for driving the air deflectors 200 to rotate can be a motor.

[0046] By setting the number of rotating pendulum blades 300 to two, not only can the covering effect of the rotating pendulum blades 300 on the lower air outlet 120 be ensured, but it is also beneficial to reduce the size of the swing blades 310. On the one hand, it avoids interference with the surrounding structure during the rotation of the rotating pendulum blades 300. On the other hand, it can also reduce the space occupied by the vertical air conditioner along the front and rear directions.

[0047] In other embodiments, the number of the air guide plates 200 may be set to three or four, and similarly, the number of the rotating blades 300 may be set to three or four.

[0048] In this embodiment, the air outlet device 020 can have an ultra-long wind mode. Figure 1 and Figure 2 In the ultra-long wind mode, the two air guide plates 200 of the upper air outlet 110 are both in the forward air guiding position, and the multiple swing blades 310 of the rotating swing blades are all in the horizontal air supply position.

[0049] Please continue to refer to Figure 1 and Figure 2 When the air outlet device 020 is operating in the ultra-long wind mode, the two air guide plates 200 located at the upper air outlet 110 are arranged opposite to each other, and the two air guide plates 200 are in the forward air guiding position, so that the conditioned air blown out through the air duct of the body 010 can be sent out through the air supply channel formed between the two air guide plates 200, so as to increase the air supply distance of the conditioned air blown out through the upper air outlet 110; at the same time, the two rotating swing blades 300 located at the lower air outlet 120 are in the horizontal air supply position, so that an air outlet gap parallel to the horizontal plane is formed between any two adjacent swing blades 310 in the upper and lower directions, so as to increase the air supply distance of the conditioned air blown out through the lower air outlet 120, thereby achieving the purpose of the air outlet device 020 operating in the ultra-long wind mode and realizing ultra-long-distance transmission of conditioned air.

[0050] In this embodiment, the air outlet device can also have a long-range and short-range soft mode. Figure 3 and Figure 4 In the long-range and short-range soft mode, the two air guide plates 200 of the upper air outlet 110 are both in the forward air guiding position. During cooling operation, the multiple swing blades 310 of the rotating swing blade 300 are in the upward air guiding position; during heating operation, the multiple swing blades 310 of the rotating swing blade 300 are in the downward air guiding position.

[0051] Please continue to refer to Figure 3 and Figure 4 When the air outlet device 020 is operating in the long-range and short-range soft mode, the two air guide plates 200 located at the upper air outlet 110 are arranged opposite to each other, and the two air guide plates 200 are in the forward air guiding position, so that the conditioned air blown out through the air duct of the body 010 can be sent out through the air supply channel formed between the two air guide plates 200, so as to increase the air supply distance of the conditioned air blown out through the upper air outlet 110; at the same time, when the vertical air conditioner is operating in the cooling mode, the two rotating swing blades 300 located at the lower air outlet 120 are in the upward air guiding position, so that the cold air is blown out upward. In this mode, the upper air outlet 110 is used to perform the "long-range projection" function, and the air supply distance can be no less than 5m. When used in larger indoor spaces such as living rooms and dining rooms, the purpose of sending the air-conditioning air far away is achieved, so that the temperature of the entire space is balanced. The lower air outlet 120 is used to perform the "near-soft" function. During cooling operation, the cold air will not blow directly, and the wind speed near is less than 0.5m / s, and the wind speed is gentle. When the user is an elderly person or a child, the adverse effects of the cold air on them can be reduced.

[0052] When the vertical air conditioner is operating in heating mode, the two rotating blades 300 located at the lower air outlet 120 are in a downward-directing position, directing hot air downward. This, combined with the positioning of the two air guide plates 200, ensures that the hot air reaches the ground, blowing on the feet rather than the head, and maintains a delivery distance of at least 5 meters. In other words, in heating mode, the upper air outlet 110 also provides a "long-range" air delivery distance of at least 5 meters to meet the temperature balance requirements of a large space. The lower air outlet 120 provides a "near-range" soft wind speed, with a gentle wind speed of less than 0.5 m / s, thereby enhancing the user experience.

[0053] Figure 10 This is a schematic diagram of the top view of the air outlet device 020 provided in this embodiment when the plurality of swing blades 310 are in the horizontal air supply position. Figure 11 This is a cross-sectional view of a vertical air conditioner provided in this embodiment. Figure 10 and Figure 11 As shown, in this embodiment, the air outlet frame 100 has an air outlet surface 130. When the air guide plate 200 is in the forward air guiding position, the plate surface of the air guide plate 200 is perpendicular to the air outlet surface 130. When the swing blade 310 is in the horizontal air supply position, the swing blade 310 is perpendicular to the air outlet surface 130.

[0054] This arrangement allows the air guide plate 200 and the swing blade 310 to be adjusted to the most favorable air outlet position when the upper air outlet 110 and the lower air outlet 120 need to deliver air to a distant place, so as to reduce obstruction to the air outlet process and allow the air-conditioned air to be blown as far as possible.

[0055] It should be noted that, in this embodiment, the relationship between the air guide plate 200 and the air outlet surface 130 when it is in the forward air guiding position, and the relationship between the swing blade 310 and the air outlet surface 130 when it is in the horizontal air supply position, are only the schemes shown in the drawings of this embodiment, and the position can be adjusted according to the air duct design of different models.

[0056] In other words, the term "vertical" refers to approximately vertical, encompassing not only the absolute vertical position between the air guide plate 200 and the air outlet surface 130, and between the swinging blades 310 and the air outlet surface 130, but also the approximately vertical position where the air guide plate 200 and the swinging blades 310 deviate appropriately from the aforementioned vertical position. The objectives are: to adjust the forward airflow position to the most favorable airflow position, i.e., the position where the air guide plate 200 does not affect airflow; and to adjust the horizontal airflow position to the position where the swinging blades 310 can best constrain the conditioned air to blow out horizontally.

[0057] Specifically in this embodiment, the air outlet surface 130 is a surface perpendicular to the air outlet direction of the air outlet frame 100, or it can be understood as the line connecting the left and right edges of the air outlet frame 100 (see Figure 11 ), or it can be understood that the wind outlet surface 130 is Figure 1 and Figure 3 The surface of the middle air outlet frame 100 is substantially parallel to the paper surface.

[0058] Please continue to refer to Figure 2 、 Figure 4 and Figure 6 In this embodiment, the upper air outlet 110 is further rotatably mounted with a plurality of sweeping blades 400 spaced apart in the vertical direction, and the rotation axes of the plurality of sweeping blades 400 are in the left-right direction. In the ultra-long wind mode, the plurality of sweeping blades 400 are in the forward blowing position (see Figure 2 and Figure 6 ); In the long-range and near-soft mode, the plurality of wind-sweeping blades 400 have an upward wind-sweeping position during cooling operation (see Figure 4 ), and the down sweep position during heating operation.

[0059] By providing a plurality of sweeping blades 400 at the upper air outlet 110, the up and down swinging of the plurality of sweeping blades 400 can be utilized to achieve up and down sweeping of air at the upper air outlet 110, thereby increasing the air outlet modes of the upper air outlet 110. Specifically, by placing the plurality of sweeping blades 400 in a forward blowing position in the ultra-long wind mode (the plurality of air guide blades 400 are substantially perpendicular to the air outlet surface 130), the obstruction to the air outlet process can be reduced, thereby enabling the conditioned air to be transported over an ultra-long distance; by placing the plurality of sweeping blades 400 in an upward sweeping position during cooling operation, the cold air at the upper air outlet 110 can also be blown upward, avoiding being blown directly onto the user's head; by placing the plurality of sweeping blades 400 in a downward sweeping position during heating operation, the hot air at the upper air outlet 110 can also be blown downward, so that the hot air falls to the ground and blows the feet instead of the head.

[0060] It should be noted that, in this embodiment, how the multiple wind sweeping blades 400 achieve up and down swinging is something that those skilled in the art can obtain based on the existing technology. It is not the focus of improvement of this application and will not be described in detail.

[0061] Please continue to refer to Figure 6 In this embodiment, the air outlet device 020 may further include an air outlet grille 500. Specifically, the air outlet grille 500 is fixedly connected to the air outlet frame 100, two air guide plates 200 are located in the front of the air outlet grille 500, and multiple air sweeping blades 400 are located in the rear of the air outlet grille 500.

[0062] Please continue to refer to Figure 6 In this embodiment, the air guide plate 200 may include an outer plate 210 and an inner plate 220 parallel to each other, and a connecting plate 230 connecting the outer plate 210 and the inner plate 220, wherein the length of the outer plate 210 is greater than the length of the inner plate 220, and the width of the outer plate 210 is greater than the width of the inner plate 220.

[0063] It should be noted that in the ultra-long wind mode, the structure of the wind guide plate 200 closer to the middle of the upper air outlet 110 is its inner plate 220, and the structures of the wind guide plate 200 closer to the left and right sides of the upper air outlet 110 are its outer plates 210.

[0064] By setting the air guide plate 200 in this form, the air-conditioning air is not only smoother and more centered when it is sent out through the upper air outlet 110, but it can also gather the air-conditioning air and send it farther.

[0065] In this embodiment, each air guide plate 200 includes a plurality of connecting plates 230 , wherein the plurality of connecting plates 230 are arranged at intervals along the up-down direction.

[0066] This arrangement can not only increase the connection reliability between the outer panel 210 and the inner panel 220 , but also suppress the deformation of the air guide plate 200 .

[0067] In this embodiment, the air outlet device 020 can also have a wide-area air supply mode. Specifically, in the wide-area air supply mode, the air outlet sides of the two air guide plates 200 are flared, and the multiple swing blades 310 of one rotating swing blade 300 are in an upward air guiding position, and the multiple swing blades 310 of the other rotating swing blade 300 are in a downward air guiding position.

[0068] This setting can increase the distribution area of the conditioned air delivered through the upper air outlet 110 in the left-right direction, and increase the distribution area of the conditioned air delivered through the lower air outlet 120 in the up-down direction, so that the air outlet device 020 can deliver air in a wide area in the left-right direction and the up-down direction at the same time.

[0069] It should be noted that, in this embodiment, when the air guide plate 200 is perpendicular to the air outlet surface 130, the side of the air guide plate 200 close to the air duct of the body 010 is its air inlet side, and the side of the air guide plate 200 away from the air duct of the body 010 is its air outlet side, that is, the rear side of the air guide plate 200 is its air inlet side, and the front side of the air guide plate 200 is its air outlet side.

[0070] It should also be noted that when the number of air guide plates 200 is more than two, the air outlet sides of the air guide plates 200 located at the left and right ends of the upper air outlet 110 can be flared; when the number of rotating pendulum blades 300 is more than two, the multiple swing blades 310 of some rotating pendulum blades 300 can be in an upward air guiding position, and the multiple swing blades 310 of another part of the rotating pendulum blades 300 can be in a downward air guiding position.

[0071] In this embodiment, the air outlet device 020 can also have a centralized air supply mode. Specifically, in the centralized air supply mode, the air outlet sides of the two air guide plates 200 are closed, and the multiple swing blades 310 of each rotating swing blade 300 are perpendicular to the air outlet surface 130.

[0072] This arrangement allows the conditioned air delivered through the upper air outlet 110 to be concentrated in the middle of the upper air outlet 110 and allows the conditioned air delivered through the lower air outlet 120 to be delivered horizontally, thereby achieving the purpose of centralized air delivery to the room.

[0073] It should be noted that, when the number of the air guide plates 200 is more than two, the air outlet sides of the air guide plates 200 located at the left and right ends of the upper air outlet 110 can be configured to be closed.

[0074] It should also be noted that in the above-mentioned wide-area air supply mode and centralized air supply mode, the multiple air sweeping blades 400 at the upper air outlet 110 can be changed in position accordingly according to the different operating requirements of the vertical air conditioner. For example: when the vertical air conditioner is operating in cooling mode, the multiple air sweeping blades 400 can be placed in an upward sweeping position; when the vertical air conditioner is operating in heating mode, the multiple air sweeping blades 400 can be placed in a downward sweeping position.

[0075] Please continue to refer to Figure 7 and Figure 8 In this embodiment, the rotating swing blade 300 may further include a supporting rib 320 . Specifically, the supporting rib 320 is fixedly connected to the plurality of swing blades 310 , and the supporting rib 320 is connected to the edge of the swing blade 310 .

[0076] This form of using support ribs 320 to fix and connect multiple swing blades 310 to form a rotating swing blade 300 can, on the one hand, achieve relative fixation of multiple swing blades 310 and a simple connection structure. On the other hand, it can also reduce obstruction to the air outlet process and reduce the attenuation of air volume.

[0077] Please continue to refer to Figure 10 and Figure 11 The supporting rib 320 is provided with an air guide surface 321. When viewed from above in the horizontal air supply position, the air guide surface 321 forms an angle with the air outlet surface 130. Figure 11 The dotted line in FIG. 1 illustrates the wind outlet surface 130 .

[0078] By setting the above-mentioned air guide surface 321 on the support rib 320, when the air outlet device 020 is supplying air horizontally, the air-conditioned air blown out through the air duct can be discharged along the air guide surface 321 of the support rib 320. The air guide surface 321 of the support rib 320 plays a certain guiding role on the air-conditioned air, so that in the horizontal air supply position, the air-conditioned air delivered through the air outlet device 020 is more concentrated, thereby improving the user experience.

[0079] In this embodiment, at the horizontal air supply position, the included angle between the air guide surface 321 and the air outlet surface 130 is β, wherein 60°<β<80°.

[0080] It should be noted that the air guide surface 321 provided on the supporting rib 320 can correct the air conditioning wind blown out from the body 010 to the right, so that the air conditioning wind is concentrated on the right side of the air outlet device 020.

[0081] In addition, by limiting the angle β between the wind guide surface 321 and the wind outlet surface 130 within the above-mentioned angle range, on the one hand, it can prevent the situation in which the air-conditioning wind is concentrated on one side of the air outlet device 020 due to the angle between the wind guide surface 321 and the wind outlet surface 130 being too small and cannot be sent into the room from the front. On the other hand, it can also prevent the situation in which the air-conditioning wind cannot be guided due to the angle between the wind guide surface 321 and the wind outlet surface 130 being too large.

[0082] Please continue to refer to Figure 7 、 Figure 8 and Figure 10 In this embodiment, there are two supporting ribs 320 , and the two supporting ribs 320 are arranged at intervals along the circumference of the swing blade 310 .

[0083] By setting the number of support ribs 320 to two, on the one hand, the connection and support reliability of each swing blade 310 can be guaranteed, and the risk of stress concentration at the connection point between the swing blade 310 and the support rib 320 caused by single-point support, which may lead to easy breakage, is reduced. At the same time, it also prevents the swing blade 310 from shaking during operation, thereby ensuring the stability of the swing blade 310. On the other hand, an air guide channel can be formed between the two support ribs 320, so that after the air-conditioning air is discharged through the air guide surface 321 of the first support rib 320, it can flow through the air guide channel formed between the two support ribs 320 and continue to be guided by the air guide surface 321 of the second support rib 320, so that the air-conditioning air can be delivered out from the front of the vertical air conditioner in a timely manner, thereby ensuring the air supply efficiency.

[0084] It should be noted that the above-mentioned “first supporting rib 320” refers to: Figure 10 After the medium-conditioned air is blown out through the air duct of the body 010, it first encounters the support rib 320; the above-mentioned "second support rib 320" refers to: Figure 10 After the middle conditioned air is blown out through the air duct of the body 010, it encounters the support rib 320. That is to say, along the flow direction of the conditioned air at the lower air outlet 120, the second support rib 320 is located downstream of the first support rib 320.

[0085] Please continue to refer to Figure 10 In this embodiment, the supporting rib 320 is a plate-shaped structure, wherein the plate surface of the supporting rib 320 facing the center of the swing blade 310 forms an air guide surface 321.

[0086] This structural form of the support rib 320, on the one hand, can reduce the volume of the support rib 320, further reducing the blocking effect of the support rib 320 on the air-conditioning wind. At the same time, it can also reduce the weight of the support rib 320, which is conducive to the lightweight design of the rotating pendulum blade 300. On the other hand, it can also ensure that the air guide surface 321 has sufficient guide area, extend the effective flow path of the air-conditioning wind on the air guide surface 321, thereby enhancing the air guide effect.

[0087] In other embodiments, the number of the supporting ribs 320 may also be three or four.

[0088] Please continue to refer to Figure 10 In this embodiment, the outline of the swing blade 310 may include a first straight edge 311, a first arc edge 312, a second straight edge 313 and a second arc edge 314 connected in sequence, wherein the first straight edge 311 is opposite to the second straight edge 313, the first arc edge 312 is opposite to the second arc edge 314, and the arcs of the first arc edge 312 and the second arc edge 314 both protrude in a direction away from the center of the swing blade 310.

[0089] By setting the swing blade 310 to the above shape, on the one hand, it can ensure that the swing blade 310 has a larger guide area, and on the other hand, it can also ensure the aesthetics of the swing blade 310 and enhance the user's visual experience.

[0090] Please continue to refer to Figure 10 In this embodiment, at the horizontal air supply position where the swing blade 310 is perpendicular to the air outlet surface 130 , the first straight edge 311 and the second straight edge 313 are arranged in the left-right direction.

[0091] The above arrangement enables the size of the swing blade 310 in the left-right direction to be reduced when the lower air outlet 120 is delivering air horizontally, thereby reducing the space occupied by the lower air outlet 120 in the left-right direction and reducing the obstruction to the air conditioning air.

[0092] Accordingly, when the swinging blade 310 is in the upward or downward air-guiding position, the first arc edge 312 and the second arc edge 314 are arranged in the left-right direction. This arrangement ensures that when the conditioned air is delivered through the lower air outlet 120, the air inlet and outlet ends of the swinging blade 310 are both straight edges, thereby ensuring that the conditioned air is more consistent when it leaves the swinging blade 310.

[0093] In addition, this embodiment further provides a vertical air conditioner, including a body 010 and the above-mentioned air outlet device 020, wherein the body 010 and the air outlet frame 100 are relatively fixedly arranged.

[0094] By arranging the air outlet device 020 in the vertical air conditioner, the vertical air conditioner accordingly has all the advantages of the air outlet device 020, which will not be described in detail here.

[0095] It should be noted that, generally speaking, one side of a vertical air conditioner is the side facing the indoor space or the indoor user activity area, and this side is the front side of the vertical air conditioner; and the side of the vertical air conditioner facing the corner or the wall is its rear side. Specifically in this embodiment, "front" refers to: the side of the vertical air conditioner facing the indoor space or the indoor user activity area, and correspondingly, "rear" refers to: the side of the vertical air conditioner facing the corner or the wall. "Up and down direction" refers to the up and down direction of the vertical air conditioner during use, that is, Figure 1 and Figure 3 The up and down directions under the viewing angle; the left and right directions refer to the left and right directions of the vertical air conditioner during use, that is, Figure 1 and Figure 3 Left and right direction of viewing angle.
