Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a cabinet air outlet mechanism and an air conditioner. Background Art

[0002] Cabinet air conditioners with axial flow fans, as indoor units, offer advantages such as a small footprint and high air volume. Circular air outlets, with uniform radius at all edges, are more conducive to axial flow fan airflow. However, fully enclosing circular air outlets is difficult. If this is not possible, achieving zero wind sensation is difficult because airflow will be blown directly out of unenclosed areas, unobstructed by the air vents. Utility Model Content

[0003] The first aspect of the present invention aims to provide a cabinet air outlet mechanism to solve the technical problem that existing air-conditioning cabinets are difficult to be compatible with the zero wind sense function.

[0004] The first aspect of the present invention provides a cabinet air outlet mechanism, including a shell, an axial flow fan, a first blade air sweeping assembly and a second blade air sweeping assembly. The shell is provided with an air outlet, and the axial flow fan, the second blade air sweeping assembly and the first blade air sweeping assembly are arranged in sequence along the air flow direction in the cabinet air outlet mechanism. The first blade air sweeping assembly is arranged at the air outlet, and the first blade air sweeping assembly can switch between a closed position for closing the air outlet and an air guiding position for at least partially exposing the air outlet; the first blade air sweeping assembly has a first air sweeping blade, and the first air sweeping blade is provided with a wind dispersion hole; in the closed position, the outer contour of the first air sweeping blade is adapted to the air outlet.

[0005] The beneficial effects brought by the utility model cabinet air outlet mechanism are:

[0006] The second blade sweeping assembly and the first blade sweeping assembly are arranged in sequence along the direction of the air flow in the cabinet air outlet mechanism, and the second blade sweeping assembly and the first blade sweeping assembly can be used to achieve sweeping in different directions. The first sweeping blade group is set at the circular air outlet, not only can the first sweeping blade be used to sweep the air, but the first sweeping blade can also be rotated to the same angle as the plane where the air outlet is located to basically close the air outlet. When the first sweeping blade is provided with a dispersion hole, the first sweeping blade can be used to adapt to the air outlet and the first blade sweeping assembly can be used to close the air outlet. The outgoing air flow is dispersed by the first sweeping blade and blown out along the dispersion hole, so that the indoor space can obtain the desired cooling or heating effect, but there is no obvious wind feeling, thereby improving the user experience.

[0007] In addition, when the first air sweeping blades are at a large angle to the horizontal direction, there are gaps between each of the first air sweeping blades, and the air can be guided through the gaps, for example, the air is discharged obliquely upward or obliquely downward at a large angle. Moreover, the large angle between the first air sweeping blades and the horizontal direction means that the angle between them and the vertical direction is small, so the airflow of the air outlet mechanism can flow forward through the air dispersion holes of the first air sweeping blades, so that there will be no obvious wind feeling in the area directly in front of the air outlet of the air conditioner cabinet. That is, in this case, it can be achieved: the air is discharged obliquely upward or obliquely downward at a large angle to meet the air flow demand for cooling or heating, but no obvious wind feeling will be generated directly in front of the air conditioner, which is beneficial to both improving the user's zero wind experience and improving the cooling or heating effect.

[0008] In an optional technical solution, the first wind-sweeping blade includes a first swing blade, a second swing blade and a middle swing blade, the middle swing blade is located in the middle of the first blade wind-sweeping assembly in the first direction, the first swing blade, the middle swing blade and the second swing blade are arranged in sequence along the first direction and the swing axes are all parallel; the edge of the middle swing blade facing the first swing blade is a first concave shape, the edge of the first swing blade facing the middle swing blade is a first convex shape, the first convex shape is adapted to the first concave shape, the edge of the middle swing blade facing the second swing blade is a second concave shape, the edge of the second swing blade facing the middle swing blade is a second convex shape, the second convex shape is adapted to the second concave shape; in the closed position, the outer contour formed by the middle swing blade, the first swing blade and the second swing blade is adapted to the air outlet.

[0009] By setting the air outlet into the above-mentioned shape and setting the first blade sweeping assembly in this way, when sweeping the air is required, the middle swing blade, the first swing blade and the second swing blade can be rotated open to expose the air outlet, so as to utilize the gap between any two adjacent first sweeping blades to achieve air supply, so that the outlet airflow can be guided along the surface of the corresponding first sweeping blade; and when there is no need to guide the air or it is necessary to enter the zero wind feeling mode, the middle swing blade, the first swing blade and the second swing blade can be rotated to close the air outlet. At this time, the outer contour jointly constructed by the middle swing blade, the first swing blade and the second swing blade forms a shape consistent with the air outlet, thereby achieving the shielding of the air outlet. Even if the air is supplied forward, since the airflow passes through the wind dispersion hole after being blocked by the middle swing blade, the first swing blade and the second swing blade, a zero wind feeling airflow can be formed, which will cause the indoor air temperature to rise or fall without bringing any wind feeling.

[0010] In the above-mentioned first blade wind sweeping assembly, by setting the two opposite edges of the middle swing blade as a first concave shape and a second concave shape respectively, and correspondingly setting a first convex shape adapted to the first concave shape on the first swing blade and a second convex shape matching the second concave shape on the second swing blade, the space occupied by the first swing blade and the second swing blade at their respective edges is reduced, so that when the first swing blade and the second swing blade are opened, the risk of interference with the edge of the air outlet is reduced, thereby increasing the rotation angle of the first swing blade and the second swing blade, and then expanding the air supply angle range of the air-conditioning cabinet.

[0011] It can be seen from this that the cabinet air outlet mechanism can not only use the swing of the first blade sweeping assembly to sweep the air in the running state to meet the multi-angle air supply requirements of the air-conditioning indoor unit, but also use the first blade sweeping assembly to block the air outlet in the shutdown state to achieve the purpose of closing the air outlet, or achieve heating or cooling in zero wind mode without producing obvious wind sensation.

[0012] In an optional technical solution, the first swing blade includes a first transition blade and a first edge blade arranged parallel to the rotation axis, and the first transition blade and the first edge blade are arranged in sequence from the middle swing blade to the end of the air outlet in the first direction in the middle; the edge of the first transition blade toward the middle swing blade is the first convex shape, and the edge of the first transition blade away from the middle swing blade is the first concave shape; the edge of the first edge blade toward the first transition blade is the first convex shape, and the edge of the first edge blade away from the middle swing blade is adapted to the edge of the air outlet; the first transition blade is at least one.

[0013] This arrangement reduces the area of ​​each of the first sweeping blades forming the first swing blade, thereby preventing the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism from protruding excessively when the first swing blade is rotated open. This reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly. It also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the first swing blade is reduced, thereby improving the ability to guide the outlet airflow.

[0014] In an optional technical solution, the second swing blade includes a second transition blade and a second edge blade arranged parallel to the rotation axis, and the second transition blade and the second edge blade are arranged in sequence in a direction away from the middle swing blade; the edge of the second transition blade toward the middle swing blade is the second convex shape, and the edge of the second transition blade away from the middle swing blade is the second concave shape; the edge of the second edge blade toward the second transition blade is the second convex shape, and the edge of the second edge blade away from the middle swing blade is adapted to the edge of the air outlet; the second transition blade is at least one.

[0015] The above arrangement reduces the area of ​​each of the first sweeping blades forming the second swing blade, thereby preventing the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism from protruding excessively when the second swing blade is rotated open. This not only reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly, but also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the second swing blade is reduced, thereby improving the ability to guide the outlet airflow.

[0016] In an optional technical solution, the middle swing blade includes a first sub-blade and a second sub-blade arranged along a first direction and parallel to the rotation axis, and the edges of the first sub-blade and the second sub-blade facing the other are both located at the center of the air outlet in the first direction; the first concave shape is located at the edge of the first sub-blade away from the second sub-blade, and the second concave shape is located at the edge of the second sub-blade away from the first sub-blade.

[0017] The above arrangement reduces the area of ​​each of the first sweeping blades forming the middle swing blade, so that when the middle swing blade is rotated open, the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism do not protrude excessively. This not only reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly, but also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the middle swing blade is reduced, thereby improving the ability to guide the outlet airflow.

[0018] In an optional technical solution, the first concave shape and the second concave shape are arranged in mirror symmetry along the center of the air outlet in the first direction; the first convex shape and the second convex shape are arranged in mirror symmetry along the center of the air outlet in the first direction.

[0019] With this arrangement, when the first sweeping blade remains horizontal, the airflow in the cabinet air outlet mechanism is guided by the first sweeping blade at both ends along the first direction with the same length, thereby improving the uniformity of the airflow and further improving the stability of the airflow.

[0020] In an optional technical solution, in the first blade wind sweeping assembly, each of the first wind sweeping blades adjacent to the first swing blade has a first protrusion; the first wind sweeping blade is in the middle in the length direction, and the first protrusion faces the edge of the first swing blade, together forming the first concave shape; the first protrusion is provided with the wind dispersion hole.

[0021] The air dispersion holes are provided on the first raised portion, so that the air can be dispersed in the area corresponding to the first raised portion, thereby increasing the number of the air dispersion holes and improving the air output.

[0022] In an optional technical solution, in the first blade wind sweeping assembly, each of the first wind sweeping blades adjacent to the second swing blade has a second protrusion; the first wind sweeping blade is in the middle in the length direction, and the second protrusion faces the edge of the second swing blade, together forming the second concave shape; the second protrusion is provided with the wind dispersion hole.

[0023] The air dispersion holes are provided on the second raised portion, so that the air can be dispersed in the area corresponding to the second raised portion, thereby increasing the number of the air dispersion holes and improving the air output.

[0024] In an optional technical solution, a sub-mouth sealing structure is provided between any two adjacent first wind-sweeping blades of the first blade wind-sweeping assembly, and the sub-mouth sealing structure includes overlapping ridges respectively arranged on the relative edges of the adjacent first wind-sweeping blades, and the overlapping ridges of each sub-mouth sealing structure are arranged in the same manner.

[0025] Such an arrangement can ensure that when the first blade sweeping assembly is in the closed position, the gap between any two adjacent first sweeping blades is blocked to prevent the outgoing air flow from leaking directly from the long gap between the two adjacent sweeping blades.

[0026] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem that cabinet air conditioners are difficult to be compatible with the zero wind sense function.

[0027] The air conditioner provided in the second aspect of the present invention includes an air conditioning cabinet and an air conditioning outdoor unit. The air conditioning outdoor unit is connected to the air conditioning cabinet via a connecting pipe. The air conditioning cabinet includes any of the cabinet air outlet mechanisms described above.

[0028] By arranging the above-mentioned cabinet air outlet mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned cabinet air outlet mechanism, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention 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.

[0041] Example 1:

[0042] Figure 1 This is a structural diagram of the cabinet air outlet mechanism provided by the first embodiment of the present invention, in which the first blade air sweeping assembly is in a closed state; Figure 2 A three-dimensional cross-sectional view of the cabinet air outlet mechanism provided by the first embodiment of the present invention, in which the first blade air sweeping assembly is in a closed state; Figure 3 This is a structural diagram of the cabinet air outlet mechanism provided by the first embodiment of the present invention, in which the first blade air sweeping assembly is in an open air outlet state; Figure 4 This is a schematic structural diagram of the cabinet air outlet mechanism provided in the first embodiment of the present invention, when the first blade sweeping assembly is in an open air outlet state and viewed from another direction; Figure 1-Figure 4 As shown, the cabinet air outlet mechanism provided by the first embodiment of the present invention includes a shell 100, an axial flow fan 410, a first blade air sweeping assembly 200 and a second blade air sweeping assembly 300. The shell 100 is provided with an air outlet 110. The axial flow fan 410, the second blade air sweeping assembly 300 and the first blade air sweeping assembly 200 are arranged in sequence along the air flow direction in the cabinet air outlet mechanism. The first blade air sweeping assembly 200 is arranged at the air outlet 110. The first blade air sweeping assembly 200 can switch between a closed position for closing the air outlet 110 and an air guiding position for at least partially exposing the air outlet 110. The first blade air sweeping assembly 200 has a first air sweeping blade, and the first air sweeping blade is provided with a wind dispersion hole 280. In the closed position, the outer contour of the first air sweeping blade is adapted to the air outlet 110.

[0043] The second blade sweeping assembly 300 and the first blade sweeping assembly 200 are arranged in sequence along the direction of the airflow in the cabinet air outlet mechanism, and the second blade sweeping assembly 300 and the first blade sweeping assembly 200 can be used to achieve sweeping in different directions. The first sweeping blade group is set at the air outlet 110, not only can the first sweeping blade be used to sweep the air, but the first sweeping blade can also be rotated to a state with the same angle as the plane where the air outlet 110 is located to basically close the air outlet 110. When the first sweeping blade is provided with a dispersion hole 280, when the first sweeping blade is used to close the air outlet 110, the outgoing air flow is dispersed by the first sweeping blade and blown out along the dispersion hole 280, so that the indoor space can obtain the desired cooling or heating effect, but without a noticeable sense of wind, thereby improving the user experience.

[0044] In addition, when the first air sweeping blades are at a large angle to the horizontal direction, there are gaps between each of the first air sweeping blades, and the air can be guided through the gaps, for example, the air is discharged obliquely upward or obliquely downward at a large angle. Moreover, the large angle between the first air sweeping blades and the horizontal direction means that the angle between them and the vertical direction is small, so the airflow of the air outlet mechanism can flow forward through the air dispersion holes 280 of the first air sweeping blades, so that there will be no obvious wind feeling in the area directly in front of the air outlet 110 of the air conditioner cabinet. That is, in this case, it can be achieved: the air is discharged obliquely upward or obliquely downward at a large angle to meet the air flow demand for cooling or heating, but no obvious wind feeling is generated directly in front of the air conditioner, which is beneficial to both improving the user's zero wind experience and improving the cooling or heating effect.

[0045] In this embodiment, the first blade sweeping assembly 200 is a vertical sweeping blade group, while the second blade sweeping assembly 300 is a horizontal sweeping blade group, wherein the second sweeping blade group 310 includes multiple second sweeping blades 310. During cooling, the cooler air needs to be blown toward the top of the indoor space as much as possible, while during heating, the hot air from the air conditioner needs to be blown toward the ground as much as possible to ensure a uniform temperature in the indoor space. Therefore, the demand for vertical sweeping in the indoor air conditioner is significantly greater than the demand for horizontal sweeping. Therefore, the first blade sweeping assembly 200, which serves as the vertical sweeping blade group, is positioned relatively forward of the cabinet air supply mechanism, i.e., at the air outlet 110, while the second blade sweeping assembly 300, which serves as the horizontal sweeping blade group, is positioned behind the first blade sweeping assembly 200.

[0046] Among them, the air dispersion holes 280 are through holes that penetrate the first air sweeping blade along the wall thickness direction. When the air flows through the air dispersion holes 280, cold air or hot air can be blown out, but the user will not feel a noticeable wind, that is, zero wind. The air dispersion holes 280 can be circular holes, rectangular holes, or elliptical holes. It should be noted that some of the drawings used in this application only schematically represent dozens of air dispersion holes 280, and the air dispersion holes 280 in the drawings are relatively large. However, this does not mean that only so many air dispersion holes 280 are respectively provided on the first air sweeping blade. In fact, there may be hundreds or thousands of air dispersion holes 280 on the first air sweeping blade, nor does it mean that the size of the air dispersion holes 280 will be so large relative to the first air sweeping blade. The above representation is used in the drawings mainly to facilitate the clarity of the diagram.

[0047] It should be noted that although the first sweeping blade has a dispersion hole 280, when the air conditioner cabinet is turned off and the air outlet 110 is sealed by the first sweeping blade, it cannot fundamentally prevent the air in front of the air outlet 110 from passing through the dispersion hole 280 and entering the interior of the air conditioner cabinet. However, since most or even most of the first sweeping blade is a solid area, it can directly block the entry of dust and the like in the air. Moreover, since the diameter of the dispersion hole 280 is relatively small, even if the air flow passes through the first sweeping blade from front to back, the air flow entering the rear of the first sweeping blade will also diffuse radially along the dispersion hole 280, and its axial flow speed will be significantly reduced, making it difficult for dust in the air to flow backward to the deeper parts of the air conditioner cabinet. In other words, when the first sweeping blade with the dispersion hole 280 is in a closed state, it can also significantly reduce the speed at which the air in front of the air conditioner cabinet enters the interior and brings dust.

[0048] like Figure 1-Figure 4 As shown, optionally, the first wind sweeping blade includes a first swing blade 220, a second swing blade 230 and a middle swing blade 210, the middle swing blade 210 is located in the middle of the first blade wind sweeping assembly 200 in the first direction, the first swing blade 220, the middle swing blade 210 and the second swing blade 230 are arranged in sequence along the first direction and the swing axes are all parallel; the edge of the middle swing blade 210 facing the first swing blade 220 is a first concave shape 241, and the first swing blade 220 faces the middle swing blade 210. The edge of the middle swing blade 210 is a first convex shape 242, which is matched with the first concave shape 241. The edge of the middle swing blade 210 toward the second swing blade 230 is a second concave shape 251, and the edge of the second swing blade 230 toward the middle swing blade 210 is a second convex shape 252, which is matched with the second concave shape 251. In the closed position, the outer contour formed by the middle swing blade 210, the first swing blade 220 and the second swing blade 230 is matched with the air outlet 110.

[0049] By setting the air outlet 110 into the above-mentioned shape and arranging the first blade sweeping assembly 200 in this way, when sweeping is required, the middle swing blade 210, the first swing blade 220 and the second swing blade 230 can be rotated to open, exposing the air outlet 110, so as to utilize the gap between any two adjacent first sweeping blades to realize air supply, so that the air flow can be guided along the surface of the corresponding first sweeping blade; and when it is not necessary to guide the air or it is necessary to enter the zero wind sense mode, the middle swing blade 210 and the first swing blade 220 can be rotated to open, so as to expose ... The middle blade 210, the first blade 220 and the second blade 230 rotate to close the air outlet 110. At this time, the outer contour jointly constructed by the middle blade 210, the first blade 220 and the second blade 230 forms a shape consistent with the air outlet 110, thereby achieving the shielding of the air outlet 110. Even if the air is supplied forward, since the air flow passes through the middle blade 210, the first blade 220 and the second blade 230 and passes through the air dispersion hole 280, a zero wind feeling airflow can also be formed, which will make the indoor air temperature rise or fall without bringing any wind feeling.

[0050] In the above-mentioned first blade wind sweeping assembly 200, by setting the two opposite edges of the middle swing blade 210 as a first concave 241 and a second concave 251 respectively, and correspondingly setting a first convex adapted to the first concave 241 on the first swing blade 220 and a second convex 252 matched with the second concave 251 on the second swing blade 230, the space occupied by the first swing blade 220 and the second swing blade 230 at their respective edges is reduced, so that during the opening process of the first swing blade 220 and the second swing blade 230, the risk of interference with the edge of the air outlet 110 is reduced, thereby increasing the rotation angle of the first swing blade 220 and the second swing blade 230, and then expanding the air supply angle range of the air-conditioning cabinet.

[0051] It can be seen from this that the cabinet air outlet mechanism can not only use the swing of the first blade sweeping assembly 200 to sweep the air in the running state to meet the multi-angle air supply requirements of the air-conditioning indoor unit, but also use the first blade sweeping assembly 200 to block the air outlet 110 in the shutdown state to achieve the purpose of closing the air outlet 110, or achieve heating or cooling in zero wind mode without producing obvious wind feeling.

[0052] like Figure 1-Figure 4As shown, optionally, the first swing blade 220 includes a first transition blade 221 and a first edge blade 222 arranged parallel to the rotation axis, and the first transition blade 221 and the first edge blade 222 are arranged in sequence in a direction away from the middle swing blade 210; the edge of the first transition blade 221 toward the middle swing blade 210 is a first convex shape 242, and the edge of the first transition blade 221 away from the middle swing blade 210 is a first concave shape 241; the edge of the first edge blade 222 toward the first transition blade 221 is a first convex shape 242, and the edge of the first edge blade 222 away from the middle swing blade 210 is adapted to the edge of the air outlet 110; the first transition blade 221 is at least one.

[0053] By setting the first swing blade 220 as a combination of the first transition blade 221 and the first edge blade 222, on the one hand, the first convex shape 242 of the first transition blade 221 can be adapted to the first concave shape 241 of the middle swing blade 210 to close the gap between the first transition blade 221 and the middle swing blade 210. On the other hand, the first concave shape 241 of the first transition blade 221 can be adapted to the first convex shape 242 of the first edge blade 222 to close the gap between the first transition blade 221 and the first edge blade 222. At the same time, the arc outer contour of the first edge blade 222 can also be used to achieve the purpose of being square with the edge of the air outlet 110.

[0054] This arrangement reduces the area of ​​each of the first sweeping blades forming the first swing blade 220. This prevents the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism from protruding excessively when the first swing blade 220 is rotated open. This reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly 300. It also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the first swing blade 220 is reduced, thereby improving the ability to direct the outlet airflow.

[0055] Among them, the first direction in this embodiment is the vertical downward direction. In this embodiment, there are six first wind sweeping blades in the first blade wind sweeping assembly 200. Correspondingly, in this embodiment, the first swing blade 220 includes a first edge blade 222 and a first transition blade 221. Of course, in another implementation, the first transition blade 221 can also be set to multiple pieces. At this time, the multiple first transition blades 221 are arranged in sequence between the middle swing blade 210 and the first edge blade 222, and any two adjacent first transition blades 221 are also adapted through the first convex shape 242 and the first concave shape 241, and the length of the first transition blade 221 gradually decreases along the center of the air outlet 110 toward the first edge blade 222.

[0056] like Figure 1-Figure 4As shown, optionally, the second swing blade 230 includes a second transition blade 231 and a second edge blade 232 arranged parallel to the rotation axis, and the second transition blade 231 and the second edge blade 232 are arranged in sequence in a direction away from the middle swing blade 210; the edge of the second transition blade 231 toward the middle swing blade 210 is a second convex shape 252, and the edge of the second transition blade 231 away from the middle swing blade 210 is a second concave shape 251; the edge of the second edge blade 232 toward the second transition blade 231 is a second convex shape 252, and the edge of the second edge blade 232 away from the middle swing blade 210 is adapted to the edge of the air outlet 110; the second transition blade 231 is at least one.

[0057] By setting the second swing blade 230 as a combination of the second transition blade 231 and the second edge blade 232, a cover can utilize the second convex shape 252 of the second transition blade 231 to adapt to the second concave shape 251 of the middle swing blade 210 to close the gap between the second transition blade 231 and the middle swing blade 210. On the other hand, the second concave shape 251 of the second transition blade 231 can be utilized to adapt to the second convex shape 252 of the second edge blade 232 to close the gap between the second transition blade 231 and the second edge blade 232. At the same time, the arc outer contour of the second edge blade 232 can also be utilized to achieve the purpose of imitating the edge of the air outlet 110.

[0058] The above arrangement reduces the area of ​​each of the first sweeping blades forming the second swing blade 230, thereby preventing the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism from protruding excessively when the second swing blade 230 is rotated open. This not only reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly 300, but also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the second swing blade 230 is reduced, thereby improving the ability to guide the outlet airflow.

[0059] In this embodiment, there are six first wind sweeping blades. Correspondingly, in this embodiment, the second swing blade 230 includes a second edge blade 232 and a second transition blade 231. Of course, in another implementation, the second transition blade 231 can also be set to multiple blades. At this time, multiple second transition blades 231 are arranged in sequence between the middle swing blade 210 and the second edge blade 232, and any two adjacent second transition blades 231 are also adapted through the second convex shape 252 and the second concave shape 251. Along the center of the air outlet 110 toward the second edge blade 232, the length of the second transition blade 231 gradually decreases.

[0060] like Figure 1-Figure 4As shown, optionally, the middle swing blade 210 includes a first sub-blade 211 and a second sub-blade 212 arranged along the first direction and parallel to the rotation axis, and the edges of the first sub-blade 211 and the second sub-blade 212 facing the other are both located at the center of the air outlet 110 in the first direction; the first concave 241 is located at the edge of the first sub-blade 211 away from the second sub-blade 212, and the second concave 251 is located at the edge of the second sub-blade 212 away from the first sub-blade 211.

[0061] The above arrangement reduces the area of ​​each first sweeping blade forming the middle swing blade 210, thereby preventing the first sweeping blades extending into the interior space of the cabinet's air outlet mechanism from protruding excessively when the middle swing blade 210 rotates open. This not only reduces interference with the interior space and prevents collision and interference with the second blade sweeping assembly 300, but also helps reduce the overall size of the cabinet's air outlet mechanism in the front-to-back direction. Furthermore, the spacing between the first sweeping blades of the middle swing blade 210 is reduced, thereby improving the ability to guide the outlet airflow.

[0062] Of course, in another implementation, the width of each first air sweeping blade can be adjusted - the height of the first air sweeping blade when the air outlet 110 is closed, so that the width of the middle part of the length direction of each first air sweeping blade is relatively uniform, and the middle swing blade 210 includes only one blade, which is mirror-symmetrical along the center position of the air outlet 110 in the height direction.

[0063] like Figure 1-Figure 4 As shown, optionally, the first concave shape 241 and the second concave shape 251 are arranged in mirror symmetry along the center of the air outlet 110 in the first direction; the first convex shape 242 and the second convex shape 252 are arranged in mirror symmetry along the center of the air outlet 110 in the first direction.

[0064] With this arrangement, when the first sweeping blade remains horizontal, the airflow in the cabinet air outlet mechanism is guided by the first sweeping blade at both ends along the first direction with the same length, thereby improving the uniformity of the airflow and further improving the stability of the airflow.

[0065] like Figure 1-Figure 4 As shown, optionally, in the first blade air sweeping assembly 200, each first air sweeping blade adjacent to the first swing blade 220 has a first protrusion 262; the first air sweeping blade is in the middle of the length direction, and the first protrusion 262 faces the edge of the first swing blade 220, together forming a first concave shape 241; the first protrusion 262 is provided with a wind dispersion hole 280.

[0066] The air dispersion holes 280 are provided on the first protrusion 262 to disperse air in the area corresponding to the first protrusion 262 , thereby increasing the number of the air dispersion holes 280 and improving the air output.

[0067] Specifically, first chamfered portions 261 are provided at both ends of the edge of the first swing blade 220 facing the center swing blade 210. When the first sweeping blade is horizontal, the area on either side of the line connecting the two ends of the first swing blade 220 with the first chamfered portion 261 can completely fall symmetrically along the line into the area without the first chamfered portion 261. The first raised portion 262 fits snugly into the first chamfered portion 261.

[0068] In this embodiment, the first protrusion 262 can be provided not only at the edge of the first transition blade 221 of the first swing blade 220 facing the first edge blade 222, but also at the edge of the first sub-blade 211 of the middle swing blade 210 facing the first transition blade 221. If there are multiple first transition blades 221, the first protrusion 262 can be provided at the edge of each first transition blade 221 facing away from the first sub-blade 211.

[0069] like Figure 1-Figure 4 As shown, optionally, in the first blade air sweeping assembly 200, each first air sweeping blade adjacent to the second swing blade 230 has a second protrusion 272; the first air sweeping blade is in the middle of the length direction, and the second protrusion 272 faces the edge of the second swing blade 230, together forming a second concave shape 251; the second protrusion 272 is provided with a wind dispersion hole 280.

[0070] The air dispersion holes 280 are provided on the second protrusion 272 to disperse air in the area corresponding to the second protrusion 272 , thereby increasing the number of the air dispersion holes 280 and improving the air output.

[0071] Specifically, the second blade 230 has second chamfered portions 271 at both ends of its edge facing the center blade 210. When the second sweeping blade 310 is horizontal, the area on either side of the line connecting the two ends of the second blade 230, with the second chamfered portion 271, can completely fall symmetrically along the line into the area without the second chamfered portion 271. The second raised portion 272 fits perfectly with the second chamfered portion 271.

[0072] In this embodiment, the second protrusion 272 can be provided not only at the edge of the second transition blade 231 of the second swing blade 230 facing the second edge blade 232, but also at the edge of the second sub-blade 212 of the middle swing blade 210 facing the second transition blade 231. If there are multiple second transition blades 231, the second protrusion 272 can be provided at the edge of each second transition blade 231 facing away from the second sub-blade 212.

[0073] like Figure 2As shown, optionally, a sub-mouth sealing structure is provided between any two adjacent first air-sweeping blades of the first blade air-sweeping assembly 200, and the sub-mouth sealing structure includes overlapping ridges 290 respectively provided on the relative edges of the adjacent first air-sweeping blades, and the overlapping ridges 290 of each sub-mouth sealing structure are arranged in the same manner.

[0074] This arrangement can ensure that when the first blade sweeping assembly 200 is in the closed position, the gap between any two adjacent first sweeping blades is blocked to prevent the outgoing air flow from leaking directly from the long gap between the two adjacent sweeping blades.

[0075] Specifically, in this embodiment, when the first air sweep blades are in the closed position, the overlapping rib 290 provided on the upper one of the two adjacent first air sweep blades is located in front of the overlapping rib 290 of the other. The overlapping ribs 290 of each sub-port sealing structure are arranged in the same manner, meaning that the overlapping ribs 290 of each sub-port sealing structure are arranged in this manner. Alternatively, they can be arranged in the opposite manner, i.e., the overlapping rib 290 of the upper first air sweep blade is located behind the overlapping rib 290 of the lower first air sweep blade. More specifically, the opposing surfaces of the two overlapping ribs 290 are both inclined surfaces, and the opposing surfaces of the overlapping ribs 290 are inclined from bottom to top and rearward.

[0077] The second embodiment further provides an air conditioner, comprising an air conditioner cabinet and an air conditioner outdoor unit, wherein the air conditioner outdoor unit is connected to the air conditioner cabinet via a connecting pipe, and the air conditioner cabinet comprises any of the above cabinet air outlet mechanisms.

[0078] By arranging the above-mentioned cabinet air outlet mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned cabinet air outlet mechanism, which will not be described in detail here.
