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] As an indoor unit of an air conditioner, an air conditioner cabinet with an axial flow fan has the advantages of small footprint and large air output. The cabinet air outlet mechanism of the air conditioner cabinet generally includes a first blade sweeping assembly and a second blade sweeping assembly located behind the first blade sweeping assembly.

[0003] However, in the prior art, usually, in order to shorten the size of the air-conditioning cabinet in the front-to-back direction, the sweeping blades of the second-blade sweeping assembly need to be as close as possible to the first-blade sweeping assembly. This causes the sweeping blades of the first-blade sweeping assembly to have a clearance gap to provide rotation space for the sweeping blades of the second-blade sweeping assembly. Since the clearance gap is large, air may leak directly from the clearance gap.

[0004] If air dispersion holes are set on the sweeping blades of the first sweeping blade assembly, although the air dispersion holes on the sweeping blades have the function of dispersing the airflow, due to the existence of these clearance gaps, the outlet airflow will still be discharged directly from the clearance gaps, weakening the zero wind function of the first sweeping blade assembly, thereby generating an obvious wind feeling in front of the air-conditioning cabinet, affecting the user experience. Utility Model Content

[0005] 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 and reduce the thickness.

[0006] The first aspect of the present invention provides a cabinet air outlet mechanism, comprising an axial flow fan, a first blade air sweeping assembly and a second blade air sweeping assembly, wherein 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;

[0007] The first blade sweeping assembly includes a first sweeping blade, the second blade sweeping assembly includes a second sweeping blade, an edge of the first sweeping blade facing the second sweeping blade is provided with a notch, the notch being configured to accommodate a portion of the second sweeping blade to swing within the notch;

[0008] The first air sweeping blade is provided with a first air dispersion hole, and the second air sweeping blade is configured to at least partially block the notch in the air outlet direction.

[0009] The beneficial effects brought by the utility model cabinet air outlet mechanism are:

[0010] Arranging the second sweeping blade to at least partially block the notch in the air outlet direction can reduce or even eliminate direct air leakage from the notch. Thus, in zero-wind mode, as much air as possible from the cabinet air outlet mechanism is discharged through the first air dispersion hole on the first sweeping blade, achieving a cooling or heating function with cooler or hotter air discharged without a sense of wind, thereby improving the user experience. Providing a notch on the edge of the first sweeping blade facing the second sweeping blade allows a portion of the second sweeping blade to swing within the notch, shortening the distance between the second sweeping blade and the first sweeping blade in the air outlet direction, and thereby reducing the overall thickness of the air conditioner cabinet equipped with this cabinet air outlet mechanism.

[0011] 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.

[0012] In an optional technical solution, the second air sweeping blade is provided with a second air dispersion hole; when the second air sweeping blade is parallel to the first air sweeping blade, the second air dispersion hole is provided in the area opposite to the second air sweeping blade and the notch.

[0013] By arranging a second air dispersion hole in the area opposite to the notch portion of the second air sweeping blade, the notch portion of the first air sweeping blade can also have an air dispersion hole for the outlet air flow to pass through, thereby expanding the total number and total area of ​​the air dispersion holes that can directly blow air out of the cabinet air outlet mechanism, and improving the cooling or heating capacity in zero wind mode.

[0014] In an optional technical solution, when the second air sweeping blade is parallel to the first air sweeping blade, the second air dispersion holes provided in the opposite area between the second air sweeping blade and the first air sweeping blade are provided opposite to the first air dispersion holes.

[0015] The second air dispersion holes on the remaining parts of the second air sweeping blade are arranged opposite to the first air dispersion holes, so that the corresponding second air dispersion holes are coaxially arranged with the first air dispersion holes, thereby reducing the resistance of the airflow passing through the corresponding second air dispersion holes and the first air dispersion holes, thereby maximizing the airflow and improving the cooling or heating capacity while meeting the requirement of zero wind sensation.

[0016] In an optional technical solution, the width of the air outlet of the cabinet air outlet mechanism gradually decreases from the middle of the air sweeping direction of the first blade air sweeping assembly to both ends, and the notch portion includes a first notch portion and a second notch portion; in the first air sweeping blade where the first notch portion and the second notch portion are set, the first notch portion is located at both ends of the length direction of the first air sweeping blade, and the second notch portion is located between the first notch portions.

[0017] By setting two different notch portions, the first notch portion and the second notch portion, it is possible to set only the second notch portion on some of the first air sweeping blades, and only the first notch portion and the second notch portion on some of the first air sweeping blades, and the first notch portion is set at the end portion in the length direction of the first air sweeping blade, which can reduce the corner size of the first air sweeping blade and prevent the corner of the first air sweeping blade from interfering with the air outlet of the above shape.

[0018] In an optional technical solution, the rotation axis of the second wind sweeping blade is arranged opposite to the center of the second notch.

[0019] The rotation axis of the second air sweeping blade is arranged relative to the center of the second notch portion, so that when the second air sweeping blade is parallel to the first air sweeping blade, that is, when the second air sweeping blade blocks the outlet air flow to the minimum extent, the second air sweeping blade can be extended into the second notch portion as much as possible to reduce the overall thickness of the cabinet air outlet mechanism.

[0020] In an optional technical solution, the first notch portion is a notch portion whose two ends are respectively located at an edge of the first air-sweeping blade facing the second blade and an end surface of the first air-sweeping blade.

[0021] The first notch is arranged on the rear edge and end face of the first air sweeping blade. Not only can the first notch be utilized to accommodate the partial swinging of the second air sweeping blade, but also the area of ​​the corner of the first air sweeping blade can be reduced, thereby preventing the corner of the first air sweeping blade from interfering with the air outlet when the first air sweeping blade swings to a vertical state or a substantially vertical state.

[0022] In an optional technical solution, the first wind-sweeping blade includes an edge wind-sweeping blade, which is located at the end of the first blade wind-sweeping assembly in the wind-sweeping direction, and the edge wind-sweeping blade is provided with the first notch portion and the second notch portion; the edge wind-sweeping blade is provided with a chamfer portion, which connects the end face of the edge wind-sweeping blade and the edge of the edge wind-sweeping blade facing away from the second wind-sweeping blade.

[0023] A first chamfer is provided at the end of the front edge of the first air sweeping blade to prevent the corner of the edge swept blade from interfering with the edge of the air outlet when the edge swept blade is kept in a vertical or nearly vertical state.

[0024] In an optional technical solution, an edge of the first air sweeping blade that faces away from the second air sweeping blade is raised in a direction away from the second air sweeping blade.

[0025] This arrangement increases the width of the first sweep blade, ensuring that the first sweep blade has sufficient airflow guide area to guide the airflow even when the distance between the second sweep blade and the first sweep blade is shortened. Furthermore, the distance between the edge of the edge sweep blade and the edge of the air outlet can be shortened, reducing air leakage from the air outlet.

[0026] In an optional technical solution, the first blade wind sweeping assembly also includes a middle support rod, the end of the first wind sweeping blade is pivotally connected to the peripheral wall of the air duct, the middle of the first wind sweeping blade is also pivotally connected to the middle support rod, and the first wind sweeping blade is collinear with the peripheral wall of the air duct and the middle support rod.

[0027] By providing a middle support rod, both ends and the middle of the first air sweeping blade can be pivotally connected to ensure the rigidity of the first air sweeping blade.

[0028] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem that it is difficult for an air conditioner cabinet to be compatible with the zero wind sense function and to reduce the thickness.

[0029] 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.

[0030] 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

[0040] 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.

[0042] Example 1:

[0043] Figure 1 This is a schematic diagram of the structure of the air outlet mechanism of the cabinet provided in the first embodiment of the present invention; Figure 2 This is a schematic diagram of the cabinet air outlet mechanism provided in the first embodiment of the present invention with the air outlet closed;

[0044] Figure 3This is a structural diagram of the cabinet air outlet mechanism provided in the first embodiment of the present invention, omitting the air conditioner housing; Figure 4 This is a schematic diagram of the structure of the cabinet air outlet mechanism provided in the first embodiment of the present invention, viewed from another direction after omitting the air conditioner cover. Figure 1-Figure 4 As shown, the cabinet air outlet mechanism provided by the first embodiment of the present invention includes an axial flow fan (not shown in the figure), a first blade air sweeping assembly 100 and a second blade air sweeping assembly 200. The axial flow fan, the second blade air sweeping assembly 200 and the first blade air sweeping assembly 100 are arranged in sequence along the air flow direction in the cabinet air outlet mechanism;

[0045] The first blade sweeping assembly 100 includes a first sweeping blade 110, and the second blade sweeping assembly 200 includes a second sweeping blade 210. A notch 112 is provided on an edge of the first sweeping blade 110 facing the second sweeping blade 210. The notch 112 is configured to accommodate a portion of the second sweeping blade 210 to swing within the notch 112.

[0046] The first air sweeping blade 110 is provided with a first air dispersing hole 111 , and the second air sweeping blade 210 is configured to at least partially block the notch 112 in the air outlet direction.

[0047] The second sweeping blade 210 is configured to at least partially block the notch 112 in the air outlet direction, which can reduce or even eliminate direct air leakage from the notch 112. Thus, in zero wind mode, the air outlet of the cabinet air outlet mechanism is discharged as much as possible through the first air dispersion hole 111 on the first sweeping blade 110, so that cooler or hotter air is discharged to perform cooling or heating functions without a sense of wind, that is, a zero wind sense function is achieved, thereby improving the user experience. The notch 112 is provided on the edge of the first sweeping blade 110 facing the second sweeping blade 210, so that a portion of the second sweeping blade 210 can swing in the notch 112, and the distance between the second sweeping blade 210 and the first sweeping blade 110 in the air outlet direction can be shortened, thereby shortening the overall thickness of the air conditioner cabinet in which the cabinet air outlet mechanism is provided.

[0048] In addition, when the first air sweeping blades 110 are at a large angle to the horizontal direction, there are gaps between each of the first air sweeping blades 110, and air can be guided through the gaps, for example, by discharging air obliquely upward or obliquely downward at a large angle. Moreover, the large angle between the first air sweeping blades 110 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 110, so that there will be no obvious sense of wind in the area directly in front of the air outlet 310 of the air conditioner cabinet. That is, in this case, it can be achieved that the air is discharged obliquely upward or obliquely downward at a large angle to meet the air flow requirements for cooling or heating, but no obvious sense of wind 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.

[0049] In this embodiment, the sweeping directions of the first and second blade sweeping assemblies 100 and 200 intersect. Specifically, the first blade sweeping assembly 100 comprises an up-and-down sweeping blade assembly, while the second blade sweeping assembly 200 comprises a left-and-right sweeping blade assembly, wherein the second sweeping blade assembly 210 comprises a plurality of second sweeping blades 210. The swing axis of the first sweeping blades 110 is horizontal, so the sweeping direction of the first blade sweeping assembly 100 is up-and-down. The swing axis of the second sweeping blades 210 is vertical, so the sweeping direction of the second sweeping blades 210 is left-and-right. Therefore, the sweeping directions of the first and second blade sweeping assemblies 100 and 200 intersect. The cabinet's air outlet mechanism can be mounted on the air duct plate 320. A front shell 330 is provided in front of the air duct plate 320. The front shell 330 is the surface shell that directly faces the user during normal use.

[0050] During cooling, the cooler air needs to be blown toward the top of the room as much as possible, while during heating, the hot air needs to be blown toward the floor as much as possible to maintain a uniform temperature. Therefore, the demand for vertical sweeping of the air conditioner indoor unit is significantly greater than the demand for horizontal sweeping. Therefore, the first blade sweep assembly 100, which serves as the vertical sweep blade group, is located relatively forward of the cabinet air supply mechanism, namely at the air outlet 310, while the second blade sweep assembly 200, which serves as the horizontal sweep blade group, is located behind the first blade sweep assembly 100.

[0051] Among them, the first air dispersion hole 111 is a through hole that passes through the first air sweeping blade 110 along the wall thickness direction. After the air flow passes through the first air dispersion hole 111, cold air flow or hot air flow can be blown out, but the user will not feel a noticeable wind sensation, that is, zero wind sensation. The first air dispersion hole 111 can be a circular hole, a rectangular hole, or an elliptical hole. Similarly, the second air dispersion hole 211 described later is also a through hole that passes through the second air sweeping blade 210 along the wall thickness direction, and the second air dispersion hole 211 can also be a hole of the above shape. It should be noted that in some of the drawings used in this application, only dozens of first air dispersion holes 111 or second air dispersion holes 211 are schematically represented in the first air sweeping blade 110 or the second air sweeping blade 210, and the first air dispersion holes 111 or the second air dispersion holes 211 in the figure are relatively large. However, this does not mean that only a certain number of first air dispersion holes 111 or second air dispersion holes 211 are provided on the first air sweep blade 110 or the second air sweep blade 210, respectively. In reality, hundreds or even thousands of first air dispersion holes 111 or second air dispersion holes 211 may be provided on the first air sweep blade 110 or the second air sweep blade 210, respectively. This does not mean that the size of the first air dispersion holes 111 or the second air dispersion holes 211 will be so large relative to the first air sweep blade 110 or the second air sweep blade 210. The above representation is used in the drawings primarily for clarity.

[0052] It should be noted that although the first air-dispersing holes 111 are provided on the first air-sweeping blade 110, when the air-conditioning cabinet is turned off and the air outlet 310 is closed by the first air-sweeping blade 110, it cannot fundamentally prevent the air in front of the air outlet 310 from passing through the first air-dispersing holes 111 and entering the interior of the air-conditioning cabinet. However, since most or even most of the first air-sweeping blade 110 is a solid area, it can directly block the entry of dust and the like in the air. Moreover, since the diameter of the first air-dispersing holes 111 is relatively small, even if the airflow passes through the first air-sweeping blade 110 from front to back, the airflow entering the rear of the first air-sweeping blade 110 will also diffuse radially along the first air-dispersing holes 111, significantly reducing its axial flow velocity and making it difficult for dust in the air to flow backward to deeper parts of the air-conditioning cabinet. In other words, when the first air-sweeping blade 110, provided with the first air-dispersing holes 111, is in a closed state, it can also significantly reduce the speed at which the air in front of the air-conditioning cabinet enters the interior and carries dust with it.

[0053] like Figure 1-Figure 4 As shown, optionally, the second air sweeping blade 210 is provided with a second air dispersion hole 211 ; when the second air sweeping blade 210 is parallel to the first air sweeping blade 110 , the second air dispersion hole 211 is provided in the area opposite to the second air sweeping blade 210 and the notch portion 112 .

[0054] By arranging the second air dispersion hole 211 in the area opposite to the notch portion 112 of the second air sweeping blade 210, the notch portion 112 of the first air sweeping blade 110 can also have an air dispersion hole for the outlet air flow to pass through, thereby expanding the total number and total area of ​​the air dispersion holes that can directly blow air out of the cabinet air outlet mechanism, and improving the cooling or heating capacity in the zero wind mode.

[0055] Specifically, in this embodiment, the second air dispersion holes 211 on the second air sweeping blade 210 can have the same shape, structure, size, distribution density, and distribution orientation as the first air dispersion holes 111 on the first air sweeping blade 110 to achieve uniform air output and reduce manufacturing costs.

[0056] like Figure 2 As shown, optionally, when the second air sweeping blade 210 is parallel to the first air sweeping blade 110 , the second air dispersion holes 211 provided in the opposite region of the second air sweeping blade 210 and the first air sweeping blade 110 are provided opposite to the first air dispersion holes 111 .

[0057] The second air dispersion holes 211 of the remaining portion of the second air sweeping blade 210 are arranged opposite to the first air dispersion holes 111, so that the corresponding second air dispersion holes 211 and the first air dispersion holes 111 are arranged coaxially, thereby reducing the resistance of the airflow passing through the corresponding second air dispersion holes 211 and the first air dispersion holes 111. Therefore, the airflow is maximized while meeting the requirement of zero wind sensation, thereby improving the cooling or heating capacity.

[0058] In addition to the notch 112, the second sweeping blade 210 also has other portions corresponding to the solid portion of the first sweeping blade 110. The notches 112 on different sweeping blades also correspond horizontally, meaning that one second sweeping blade 210 can correspond to the notches 112 at the same horizontal position on multiple first sweeping blades 110. Second air dispersion holes 211 can also be provided between the areas of the second sweeping blade 210 corresponding to the notches 112. These second air dispersion holes 211 are coaxially arranged with the first air dispersion holes 111.

[0059] like Figure 1-Figure 4 As shown, optionally, the air outlet 310 of the cabinet air outlet mechanism gradually decreases in width from the middle of the air sweeping direction of the first blade air sweeping assembly 100 to both ends; the notch portion 112 includes a first notch portion 113 and a second notch portion 114; in the first air sweeping blade 110 where the first notch portion 113 and the second notch portion 114 are provided, the first notch portion 113 is located at both ends of the length direction of the first air sweeping blade 110, and the second notch portion 114 is located between the first notch portion 113.

[0060] By providing two different notch portions 112, namely the first notch portion 113 and the second notch portion 114, it is possible to provide only the second notch portion 114 on some of the first air sweeping blades 110, and only the first notch portion 113 and the second notch portion 114 on some of the first air sweeping blades 110, and the first notch portion 113 is provided at the end portion in the length direction of the first air sweeping blade 110, which can reduce the corner size of the first air sweeping blade 110 and prevent the corner of the first air sweeping blade 110 from interfering with the air outlet 310 of the above-mentioned shape.

[0061] The first blade sweep assembly 100 sweeps air in a vertical or vertical direction, so the width of the air outlet 310 gradually decreases from the middle of its height toward its top and bottom. More specifically, in this embodiment, the air outlet 310 can be circular. Obviously, the width of a circular air outlet 310 gradually decreases from the middle of its height toward its top and bottom.

[0062] like Figure 1-Figure 4 As shown, optionally, the rotation axis of the second sweeping blade 210 is arranged opposite to the center of the second notch portion 114 .

[0063] The rotation axis of the second air sweeping blade 210 is arranged relative to the center of the second notch portion 114, so that when the second air sweeping blade 210 is parallel to the first air sweeping blade 110, that is, when the second air sweeping blade 210 blocks the air flow to the minimum extent, the second air sweeping blade 210 can be extended into the second notch portion 114 as much as possible to reduce the overall thickness of the cabinet air outlet mechanism.

[0064] Specifically, in this embodiment, the second notch 114 is a generally symmetrical shape, more specifically, a generally arc-shaped shape. The arc-shaped second notch 114 is chamfered with the arc of the rear edge of the first sweeping blade 110. The rotation axis of the second sweeping blade 210 is positioned relative to the center of the second notch 114. Specifically, the center of the second notch 114 can be located directly in front of the rotation axis of the second sweeping blade 210.

[0065] like Figure 1-Figure 4 As shown, optionally, the first notch portion 113 is a notch portion 112 with two ends respectively located at an edge of the first sweeping blade 110 facing the second blade and an end surface of the first sweeping blade 110 .

[0066] The first notch portion 113 is provided on the rear edge and end face of the first air sweeping blade 110. Not only can the first notch portion 113 be utilized to accommodate the partial swinging of the second air sweeping blade 210, but also the area of ​​the corner of the first air sweeping blade 110 can be reduced, thereby preventing the corner of the first air sweeping blade 110 from interfering with the air outlet 310 when the first air sweeping blade 110 swings to a vertical state or a substantially vertical state.

[0067] Specifically, in this embodiment, the first notch 113 can also be roughly in the shape of a quarter arc, and the rotation axis of the second sweeping blade 210 corresponding to the first notch 113 can correspond to the center of the quarter arc, that is, the rotation axis of the second sweeping blade 210 is located directly behind the center. Of course, in addition to corresponding to the first notch 113, this second sweeping blade 210 can also correspond to the second notch 114.

[0068] like Figure 1-Figure 4 As shown, optionally, the first wind sweeping blade 110 includes an edge wind sweeping blade 115, which is located at the end of the first blade wind sweeping assembly 100 in the wind sweeping direction, and the edge wind sweeping blade 115 is provided with a first notch portion 113 and a second notch portion 114; the edge wind sweeping blade 115 is provided with a chamfered portion, which connects the end face of the edge wind sweeping blade 115 and the edge of the edge wind sweeping blade 115 facing away from the second wind sweeping blade 210.

[0069] A first chamfer is provided at the end of the front edge of the first sweeping blade 110 to prevent the corner of the edge sweeping blade 115 from interfering with the edge of the air outlet 310 when the edge sweeping blade 115 is kept in a vertical or nearly vertical state.

[0070] Specifically, in this embodiment, there are six first air sweeping blades 110, which are arranged vertically. The first and last first air sweeping blades 110 from top to bottom are edge air sweeping blades 115. That is, the edge air sweeping blades 115 are located at the ends of the first air sweeping blade 110 assembly in the air sweeping direction. The rear edges of the edge air sweeping blades 115 are provided with a second notch 114 and a first notch 113, while the front edges of the edge air sweeping blades 115 are provided with a chamfered portion. Thus, when the first air sweeping blades 110 are in a state of closing the air outlet 310, both the upper and lower edges of the edge air sweeping blades 115 have a chamfered portion or a first notch 113 at their ends to reduce the corner size of the first air sweeping blades 110 and prevent interference with the edge of the air outlet 310.

[0071] like Figure 1-Figure 4 As shown, optionally, the edge of the first sweeping blade 110 facing away from the second sweeping blade 210 is convex in a direction facing away from the second sweeping blade 210 .

[0072] This arrangement increases the width of the first sweep blade 110, ensuring that the first sweep blade 110 has sufficient airflow guide area to guide the airflow even if the distance between the second sweep blade 210 and the first sweep blade 110 is shortened. Furthermore, the distance between the edge of the edge sweep blade 115 and the edge of the air outlet 310 can be shortened, reducing air leakage from the air outlet 310.

[0073] In this embodiment, the front edge of the lowest edge sweep blade 115 can be convexly curved. This minimizes the gap between the lower edge of the edge sweep blade 115 and the bottom edge of the air outlet 310 when the first sweep blade 110 closes the air outlet 310. The rear edge of the edge sweep blade 115 is substantially parallel to the front edge. The front and rear edges of the remaining first sweep blades 110 are also substantially parallel to the front and rear edges of the edge sweep blade 115. Thus, when the first blade sweep assembly 100 closes the air outlet 310, i.e., when the first sweep blade 110 rotates downward from a horizontal position to a vertical or nearly vertical position, the first sweep blade 110 as a whole, with its lower portion having the downwardly convex front edge of the edge sweep blade 115 and its upper portion having the raised portion between the second notch 114 and the first notch 113, minimizes the gap between the corresponding portion of the air outlet 310, thereby reducing air leakage from the air outlet 310.

[0074] like Figure 1 、 Figure 3 and Figure 4 As shown, optionally, the first blade sweeping assembly 100 also includes a middle support rod 120, the end of the first sweeping blade 110 is pivotally connected to the peripheral wall of the air duct, and the middle of the first sweeping blade 110 is also pivotally connected to the middle support rod 120, and the positions of the first sweeping blade 110, the peripheral wall of the air duct and the middle support rod 120 are collinear.

[0075] By providing the middle support rod 120 , both ends and the middle of the first air sweeping blade 110 can be pivotally connected to ensure the rigidity of the first air sweeping blade 110 .

[0076] Furthermore, in this embodiment, the middle portion of each first sweep blade 110 is pivotally connected to the sweep drive rod 130. Specifically, the pivotal connection between the sweep drive rod 130 and the first sweep blade 110 is located in front of the middle region of the first sweep blade 110, while the pivotal connection between the first sweep blade 110 and the middle support rod 120 is located in the rear of the middle region of the first sweep blade 110. The pivotal connection between the sweep drive rod 130 and the middle support rod 120 at the middle of any two first sweep blades 110, respectively, forms a parallelogram, thereby utilizing the parallelogram mechanism to ensure the synchronization of the movements of the first sweep blades 110.

[0078] 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.

[0079] 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.
