Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a cabinet air supply 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 a small footprint and a large air output. However, air conditioner cabinets with axial flow fans are usually made relatively thin. In this case, the space for the upper and lower sweeping blades in the body is limited. If the sweeping blades are required to play the role of completely sealing the air outlet in the closed state, the width of the sweeping blades must meet a certain size, which will inevitably increase the thickness of the air conditioner cabinet, thereby affecting the air duct structure inside the air conditioner cabinet and the design and layout of the internal structure. In particular, if the sweeping blades are all inside the cabinet shell, the thickness of the air outlet frame is increased, resulting in the heat exchange air after coming out of the air duct having an excessively long internal distance on the front side of the air duct, which will significantly affect the air supply effect. Utility Model Content

[0003] The first aspect of the present invention aims to provide a cabinet air supply mechanism to solve the technical problem of insufficient width of upper and lower air sweeping blades of existing air-conditioning cabinets.

[0004] The first aspect of the present invention provides a cabinet air supply mechanism, including an axial flow fan, a front panel and upper and lower air sweeping blades, the front panel is provided with an air outlet, the axial flow fan is located upstream of the upper and lower air sweeping blades, and the upper and lower air sweeping blades are configured as follows: when rotated to a horizontal position, the front edges of at least a part of the upper and lower air sweeping blades extend forward from the air outlet; when rotated to a vertical position, the air outlet can be closed.

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

[0006] By configuring the upper and lower air sweeping blades to rotate to a horizontal position so that the front edges of at least a portion of the upper and lower air sweeping blades extend out of the air outlet, part of the width area of ​​the upper and lower air sweeping blades, that is, part of the area downstream along the air outlet direction when the upper and lower air sweeping blades are in a horizontal position, can be transferred to the outside of the front panel and no longer occupy the space of the air duct cavity inside the front panel, thereby reducing the influence of the width of the upper and lower air sweeping blades on the thickness of the air-conditioning cabinet, thereby increasing the width of the upper and lower air sweeping blades, so that when the upper and lower air sweeping blades are in a vertical state, they can close the air outlet without the need to set up other mechanisms to close the air outlet separately, thereby improving the reliability of the air-conditioning cabinet.

[0007] In an optional technical solution, the upper and lower wind sweeping blades include a wind sweeping plate body and a pivot shaft portion. When the wind sweeping plate body is in a horizontal position, the pivot shaft portion corresponds to the middle portion of the wind sweeping plate body in the width direction.

[0008] With the above arrangement, when the pivot axis is relatively close to the air outlet and the sweeping plate is in a vertical position, the front surfaces of the upper and lower sweeping blades, i.e., the front surfaces of the sweeping plate, can be flush with the front panel. Furthermore, by positioning the pivot axis of the upper and lower sweeping blades in this manner, the center of gravity of the sweeping plate is relatively close to the axis of the pivot axis when the sweeping plate is in a horizontal position, thereby eliminating the need for the motor to provide significant torque. Furthermore, even when the sweeping plate is not in a horizontal position, the distance between the center of gravity of the sweeping plate and the axis of the pivot axis is relatively short, which also helps reduce the torque of the motor during the sweeping operation of the upper and lower sweeping blades.

[0009] Furthermore, when the upper and lower sweep blades are horizontal, more of the sweep plate can be positioned in front of the pivot axis, reducing the proportion of the sweep plate behind the pivot axis. This increases the width of the sweep plate while minimizing the overall thickness of the air conditioner cabinet.

[0010] In an optional technical solution, the cabinet air supply mechanism includes a transmission assembly, the transmission assembly includes a first connecting rod and a second connecting rod, a plurality of second connecting rods are fixedly connected to the first connecting rod, and each second connecting rod is pivotally connected to the upper and lower air sweeping blades;

[0011] The upper and lower wind sweeping blades include a transmission connection portion fixedly connected to the wind sweeping plate body. When the wind sweeping plate body is in a state of closing the air outlet, the transmission connection portion is located at the rear side of the wind sweeping plate body; when the wind sweeping plate body is in a horizontal position, the pivotal position of the transmission connection portion and the second connecting rod is located behind the pivot shaft portion.

[0012] By using a first connecting rod to fixedly connect multiple second connecting rods, and using the second connecting rod to pivotally connect with the upper and lower wind sweeping blades, the synchronous movement of the multiple upper and lower wind sweeping blades can be achieved. When the wind sweeping plate body is in a horizontal position, the pivotal position of the transmission connection portion and the second connecting rod is arranged to be located behind the pivot axis portion. The space between the multiple second connecting rods can be used to accommodate the rear portion of the wind sweeping plate body in the horizontal position, preventing the rear portion of the horizontal wind sweeping plate body from interfering with the first and second connecting rods. This eliminates the need to provide a notch at the rear portion of the upper and lower wind sweeping blades to avoid the second connecting rod and the first connecting rod, thereby ensuring the wind guide area of ​​the upper and lower wind sweeping blades. In addition, this arrangement can fully utilize the size of the transmission connection portion to reduce the length of the second connecting rod and increase the rigidity of the second connecting rod.

[0013] In an optional technical solution, the horizontal width of the air outlet gradually shortens upward and downward from the middle of the height direction of the air outlet, and the upper and lower air-sweeping blades include a first air-sweeping blade, which has a first cut corner portion; when the first air-sweeping blade is in a horizontal position, the first cut corner portion is located at both ends of the front edge of the first air-sweeping blade.

[0014] Since the pivot axis cannot be located exactly at the air outlet, that is, it cannot be located at the air outlet opening position of the front panel, but is located behind the front panel, so by providing a first cut corner portion at the front edge end of the first air sweeping blade, interference with the front panel can be prevented when the first air sweeping blade swings, for example, thereby facilitating an increase in the swing angle of the first air sweeping blade to expand the air outlet range.

[0015] In an optional technical solution, the upper and lower wind sweeping blades are further provided with a first protrusion, and the first protrusion is adapted to the first corner cutting portion.

[0016] By arranging the first protrusion to be adapted to the first cut corner portion, when the upper and lower air sweeping blades are in the closed state, the first protrusion can make up for the vacancy of the first cut corner portion, thereby achieving relatively complete shielding of the air outlet.

[0017] In an optional technical solution, the upper and lower air sweeping blades include a second air sweeping blade, and the second air sweeping blade has a second cut corner portion; when the second air sweeping blade is in a horizontal position, the second cut corner portion is located at both ends of the rear edge of the second air sweeping blade.

[0018] A second chamfered portion is provided at the rear edge of the second air sweeping blade to prevent the end of the rear edge of the second air sweeping blade from interfering with the air duct wall in the air outlet when the second air sweeping blade is in the open position, especially when the second air sweeping blade is in an upward posture.

[0019] In an optional technical solution, the upper and lower wind sweeping blades are further provided with a second protrusion, and the second protrusion is adapted to the second corner cutting portion.

[0020] By arranging the second protrusion to match the second cut corner portion, the second protrusion can make up for the gap in the second cut corner portion when the upper and lower air sweeping blades are in the closed state, thereby achieving relatively complete shielding of the air outlet.

[0021] In an optional technical solution, the upper and lower air sweeping blades are configured as follows: when rotated to a vertical position, the lower edge of the upper upper and lower air sweeping blade of two adjacent upper and lower air sweeping blades overlaps the front side of the upper edge of the lower upper and lower air sweeping blade.

[0022] When the upper and lower sweep blades close the air outlet, the gravity acting on the sweep plate, because the sweep plate is located in front of the pivot shaft, creates a rotational torque on the upper and lower sweep blades. This torque causes the upper edge of the sweep plate to move toward the rear of the air outlet, while the upper edge of the sweep plate moves toward the front of the air outlet. This arrangement allows the forward movement of the upper edge of the lower sweep blade to suppress the rearward movement of the lower edge of the upper sweep blade, thereby stabilizing the upper and lower sweep blades when closing the air outlet.

[0023] In an optional technical solution, a sub-mouth sealing structure is provided between any two adjacent upper and lower air sweeping blades, and the sub-mouth sealing structure includes overlapping ridges respectively provided on the opposite edges of the adjacent upper and lower air sweeping blades.

[0024] With this arrangement, when the upper and lower air sweeping blades are in a vertical position, the gap between any two upper and lower air sweeping blades can be blocked by the sub-mouth sealing structure formed by the overlapping ridges, preventing dust in the air from entering through the long gap between the two adjacent upper and lower air sweeping blades.

[0025] The second aspect of the present invention aims to provide an air conditioner to solve the technical problem of insufficient width of upper and lower air sweeping blades of an air conditioner cabinet.

[0026] The air conditioner provided in the second aspect of the present invention includes an air conditioner outdoor unit and an air conditioner cabinet unit. The air conditioner outdoor unit is connected to the air conditioner cabinet unit through a refrigerant connecting pipe. The air conditioner cabinet unit includes any of the cabinet air supply mechanisms described above.

[0027] By arranging the above-mentioned cabinet air supply mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned cabinet air supply mechanism, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] 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.

[0043] Unless otherwise specified, the definitions of directions in this application are as follows: the front refers to the side of the air-conditioning cabinet facing the main indoor space, and the back refers to the side of the air-conditioning cabinet facing the wall closest to it. The bottom refers to the side of the air-conditioning cabinet facing the ground. The top refers to the side of the air-conditioning cabinet facing the roof. Left and right can be defined based on the above-mentioned front, back and bottom, that is, when the observer faces the wall closest to the air-conditioning cabinet, the observer's left hand direction is the left side, and the observer's right hand direction is the right side. In addition, the inside and outside are defined based on the components in the shape of a cavity, box or cylinder. The side of the cavity, box or cylinder facing its internal space is the inside, and the outside is the side of the cavity, box or cylinder facing its external space.

[0044] Example 1:

[0045] Figure 1 This is a schematic diagram of the structure of the cabinet air supply mechanism provided in Example 1 of the present utility model; Figure 1 As shown, the cabinet air supply mechanism provided by the first embodiment of the present invention includes an axial flow fan 420, a front panel 100 and upper and lower air sweeping blades 200. The front panel 100 is provided with an air outlet 110. The axial flow fan 420 is located upstream of the upper and lower air sweeping blades 200. The upper and lower air sweeping blades 200 are configured so that when they are rotated to a horizontal position, the front edges of at least a part of the upper and lower air sweeping blades 200 extend forward from the air outlet 110; when they are rotated to a vertical position, the air outlet 110 can be closed.

[0046] By configuring the upper and lower air sweeping blades 200 to rotate to a horizontal position so that the front edges of at least a portion of the upper and lower air sweeping blades 200 extend out of the air outlet 110, part of the width area of ​​the upper and lower air sweeping blades 200, that is, part of the area downstream along the air outlet direction when the upper and lower air sweeping blades 200 are in a horizontal position, can be transferred to the outside of the front panel 100, no longer occupying the space of the air duct cavity inside the front panel 100, thereby reducing the influence of the width of the upper and lower air sweeping blades 200 on the thickness of the air-conditioning cabinet, thereby increasing the width of the upper and lower air sweeping blades 200, so that when the upper and lower air sweeping blades 200 are in a vertical state, they can close the air outlet 110 without setting up other mechanisms to close the air outlet 110 separately, thereby improving the reliability of the air-conditioning cabinet.

[0047] Specifically, the axial flow cabinet air supply mechanism in this embodiment further includes left and right sweep blades 410. The axial flow fan 420, left and right sweep blades 410, and upper and lower sweep blades 200 are arranged sequentially along the air outlet direction. The axial flow fan 420 and left and right sweep blades 410 are all disposed within the air duct wall 120, which is fixed relative to the front panel 100. Because the upper and lower sweep blades 200 are located at the front end of the axial flow cabinet air supply mechanism, portions of the upper and lower sweep blades 200 can extend out of the air outlet 110 when the upper and lower sweep blades 200 are in a horizontal position.

[0048] Figure 2 A three-dimensional cross-sectional view of the cabinet air supply mechanism provided in Example 1 of the present utility model; Figure 3 This is a schematic diagram of the appearance of an air conditioning cabinet using the cabinet air supply mechanism provided in Example 1 of the present utility model;

[0049] Figure 4 This is a right side view of the appearance of an air conditioning cabinet using the cabinet air supply mechanism provided in the first embodiment of the present invention; Figure 5 This is a schematic diagram of the appearance of an air-conditioning cabinet applied to the cabinet air supply mechanism provided in the first embodiment of the present invention as viewed from another direction; Figure 1-Figure 5 As shown, optionally, the upper and lower wind sweeping blades 200 include a wind sweeping plate body 201 and a pivot shaft portion 202. When the wind sweeping plate body 201 is in a horizontal position, the pivot shaft portion 202 corresponds to the middle portion of the wind sweeping plate body 201 in the width direction.

[0050] With the above arrangement, when the pivotal shaft 202 is relatively close to the air outlet 110 and the air sweeping plate 201 is in a vertical position, the front surfaces of the upper and lower air sweeping blades 200, i.e., the front surfaces of the air sweeping plate 201, can be flush with the front panel 100. Furthermore, by positioning the pivotal shaft 202 of the upper and lower air sweeping blades 200 in this manner, the center of gravity of the air sweeping plate 201 is relatively close to the axis of the pivotal shaft 202 when the air sweeping plate 201 is in a horizontal position, thereby eliminating the need for the motor to provide a large torque. Furthermore, even when the air sweeping plate 201 is not in a horizontal position, the distance between the center of gravity of the air sweeping plate 201 and the axis of the pivotal shaft 202 is relatively short, which also helps reduce the torque of the motor when the upper and lower air sweeping blades 200 sweep air.

[0051] Furthermore, when the upper and lower sweep blades 200 are in a horizontal position, more of the sweep plate 201 can be positioned in front of the pivot shaft 202, thereby reducing the portion of the sweep plate 201 behind the pivot shaft 202. This increases the width of the sweep plate 201 while minimizing the overall thickness of the air conditioner cabinet.

[0052] Specifically, when the sweeping plate 201 of the upper and lower sweeping blades 200 is in a horizontal position, the horizontal distance between the front edge of the upper and lower sweeping blades 200 and the pivot shaft 202 is greater than the horizontal distance between the pivot shaft 202 and the front surface of the front panel 100 .

[0053] Figure 6 A three-dimensional schematic diagram of another implementation of the cabinet air supply mechanism provided in the first embodiment of the present utility model; Figure 7 A three-dimensional schematic diagram of another implementation of the cabinet air supply mechanism provided in the first embodiment of the present invention, viewed from another direction; Figure 8 This is a three-dimensional schematic diagram of another implementation of the cabinet air supply mechanism provided in the first embodiment of the present invention, viewed from another direction. Figure 1-Figure 2 and Figure 6-Figure 8 As shown, optionally, the cabinet air supply mechanism includes a transmission assembly 300, the transmission assembly 300 includes a first connecting rod 310 and a second connecting rod 320, a plurality of second connecting rods 320 are fixedly connected to the first connecting rod 310, and each second connecting rod 320 is pivotally connected to the upper and lower air sweeping blades 200;

[0054] The upper and lower air sweeping blades 200 include a transmission connection portion 203 fixedly connected to the air sweeping plate body 201. When the air sweeping plate body 201 is in a state of closing the air outlet 110, the transmission connection portion 203 is located on the rear side of the air sweeping plate body 201; when the air sweeping plate body 201 is in a horizontal position, the pivotal position of the transmission connection portion 203 and the second connecting rod 320 is located behind the pivot shaft portion 202.

[0055] The first connecting rod 310 is used to fixedly connect the plurality of second connecting rods 320, and the second connecting rods 320 are pivotally connected to the upper and lower air sweep blades 200, thereby achieving synchronous movement of the plurality of upper and lower air sweep blades 200. When the air sweep plate 201 is in a horizontal position, the pivotal connection between the transmission connection portion 203 and the second connecting rod 320 is located behind the pivot shaft portion 202. This allows the space between the plurality of second connecting rods 320 to accommodate the rear portion of the air sweep plate 201 in the horizontal position, preventing interference between the rear portion of the horizontal air sweep plate 201 and the first and second connecting rods 310 and 320. This eliminates the need for notches in the rear portions of the upper and lower air sweep blades 200 to allow for clearance between the second and first connecting rods 320 and 310, thereby ensuring a sufficient air guide area for the upper and lower air sweep blades 200. Furthermore, this arrangement fully utilizes the size of the transmission connection portion 203, reducing the length of the second connecting rod 320 and increasing its rigidity.

[0056] Specifically, in this embodiment, a plurality of second connecting rods 320 are arranged in parallel. Figure 1-Figure 2 As shown, the plurality of second connecting rods 320 may be perpendicular to the first connecting rod 310. In another implementation, as shown in FIG. Figure 6-Figure 8As shown, multiple second connecting rods 320 may also form the same acute angle with the first connecting rod 310. The free ends of the second connecting rods 320 are pivotally connected to the transmission connection portion 203. The second connecting rods 320 drive the transmission connection portion 203 to move, thereby driving the upper and lower air sweeping blades 200 to oscillate. In this embodiment, the transmission connection portion 203 is a plate portion perpendicular to the air sweeping plate 201, which is pivotally connected to the second connecting rods 320 via a pivot axis.

[0057] like Figure 1-Figure 3 and Figure 5-Figure 8 As shown, optionally, the horizontal width of the air outlet 110 gradually shortens upward and downward from the middle of the height direction of the air outlet 110, and the upper and lower air sweeping blades 200 include a first air sweeping blade 210, and the first air sweeping blade 210 has a first cut corner portion 211; when the first air sweeping blade 210 is in a horizontal position, the first cut corner portion 211 is located at both ends of the front edge of the first air sweeping blade 210.

[0058] Since the pivot shaft portion 202 cannot be located exactly at the air outlet 110, that is, it cannot be located at the opening position of the air outlet 110 of the front panel 100, but is located behind the front panel 100, by providing a first cut corner portion 211 at the front edge end of the first air sweeping blade 210, it is possible to prevent interference with the front panel 100 when the first air sweeping blade 210 swings, thereby facilitating an increase in the swing angle of the first air sweeping blade 210 to expand the air outlet range.

[0059] In this embodiment, the air outlet 110 is circular. Of course, in other implementations, the air outlet 110 can also be a regular octagon, regular hexagon, or other shape. The air sweeping plates 201 of the upper and lower air sweeping blades 200 are arranged vertically within the air outlet 110. The first air sweeping blade 210 is located at the top of all the upper and lower air sweeping blades 200. Specifically, when the upper and lower air sweeping blades 200 are in a closed position (i.e., vertical or nearly vertical), the first corner cutout 211 is located at the bottom of the first air sweeping blade 210.

[0060] Although the leading edge of the first sweep blade 210 is exposed outside the air outlet 110 when the first sweep blade 210 is in a horizontal position, the upper and lower sweep blades 200 can close the air outlet 110. Therefore, when closed, the overall shape of the multiple upper and lower sweep blades 200 is consistent with the shape of the air outlet 110. Specifically, in this embodiment, when closed, the multiple upper and lower sweep blades 200 form a circular shape. Consequently, the left and right ends of the first sweep blade 210, which is farther from the center of the air outlet 110, are more pointed, with the tips located at the bottom of the first sweep blade 210. Consequently, when the first sweep blade 210 is tilted upward from its horizontal position, the tips of the two ends of the first sweep blade 210 may interfere with the edge of the air outlet 110 above it. Therefore, the provision of the first chamfered portion 211 prevents interference with the edge of the air outlet 110, thereby maintaining the swing angle of the first sweep blade 210.

[0061] like Figure 1-Figure 3 and Figure 5-Figure 7 As shown, optionally, each point on the first cut corner portion 211 and the point on the rear edge of the first sweeping blade 210 at the same axial position projected on the rotation axis of the first sweeping blade 210, each point on the first cut corner portion 211 is closer to the rotation axis of the first sweeping blade 210.

[0062] This arrangement keeps the size of the first chamfered portion 211 within the range of the rear edge of the first sweeping blade 210 when in a horizontal position. Since the upper and lower sweeping blades 200 close the air outlet 110, the upper edge of the first sweeping blade 210—the rear edge of the first sweeping blade 210 in a horizontal position—does not interfere with the edge of the air outlet 110. Consequently, when the first sweeping blade 210 is raised from its horizontal position, the first chamfered portion 211 also does not interfere with the edge of the air outlet 110. In other words, even when the first sweeping blade 210 is raised to a near-vertical position, it does not interfere with the edge of the air outlet 110, thereby expanding the air sweeping range of the air conditioner cabinet.

[0063] Specifically, in this embodiment, the air sweeping plate 201 can be a flat plate. The axis of the pivot shaft 202 is projected onto the air sweeping plate 201 in a direction perpendicular to the air sweeping plate 201. The first chamfered portion 211 is located on one side of the projected position, which, in the air discharge state, is on the downstream side of the air discharge direction. The rear edges of the upper and lower air sweeping blades 200, when in a horizontal position, are located on the other side of the projected position. The area on one side of the projected position with the first chamfered portion 211 is completely within the area on the other side where the rear edges are located.

[0064] like Figure 1-Figure 3 and Figure 5-Figure 8 As shown, optionally, the upper and lower air sweeping blades 200 are further provided with a first protrusion 212 , and the first protrusion 212 is adapted to the first corner cutting portion 211 .

[0065] By arranging the first protrusion 212 to be adapted to the first cut corner portion 211 , when the upper and lower air sweeping blades 200 are in the closed state, the first protrusion 212 can make up for the vacancy of the first cut corner portion 211 , thereby achieving relatively complete shielding of the air outlet 110 .

[0066] The first chamfered portions 211 are provided at both ends of the front edge of the first sweeping blade 210, and first raised portions 212 are provided at positions of the remaining upper and lower sweeping blades 200 corresponding to the front edge of the first sweeping blade 210. The first raised portions 212 are adapted to the first chamfered portions 211, meaning that the first raised portions 212 correspond to the first chamfered portions 211 in position, shape, and size. The first raised portions 212 can cover the gap in the first sweeping blade 210 created by the first chamfered portions 211.

[0067] like Figure 1-Figure 3 and Figure 5-Figure 8 As shown, optionally, the upper and lower air sweeping blades 200 include a second air sweeping blade 220, and the second air sweeping blade 220 has a second cut corner portion 221; when the second air sweeping blade 220 is in a horizontal position, the second cut corner portion 221 is located at both ends of the rear edge of the second air sweeping blade 220.

[0068] A second chamfered portion 221 is provided at the rear edge of the second air sweeping blade 220 to prevent the end of the rear edge of the second air sweeping blade 220 from interfering with the air duct wall 120 in the air outlet 110 when the second air sweeping blade 220 is in the open position, especially when the second air sweeping blade 220 is in an upward posture.

[0069] Specifically, the second air sweeping blade 220 is located at the lower part of all the upper and lower air sweeping blades 200, that is, when the upper and lower air sweeping blades 200 are in a state of closing the air outlet 110, that is, when the upper and lower air sweeping blades 200 are in a vertical state or a near-vertical state, the second cut corner portion 221 is located at the upper part of the second air sweeping blade 220.

[0070] like Figure 1-Figure 3 and Figure 5-Figure 7 As shown, optionally, each point on the second cut corner portion 221, and the points on the rear edge of the second sweeping blade 220 at the same axial position projected on the rotation axis of the second sweeping blade 220, each point on the second cut corner portion 221 is closer to the rotation axis of the second sweeping blade 220.

[0071] This arrangement controls the size of the second chamfered portion 221 to within the range of the front edge of the second sweeping blade 220 when in a horizontal position. Since the lower and upper sweeping blades 200 close the air outlet 110, the lower edge of the second sweeping blade 220—the front edge of the second sweeping blade 220 when in a horizontal position—will not interfere with the edge of the air outlet 110. Consequently, when the second sweeping blade 220 is raised from its horizontal position, the second chamfered portion 221 will not interfere with the air duct wall 120 inside the air outlet 110. In other words, even when the second sweeping blade 220 is raised to a near-vertical position, it will not interfere with the air duct wall 120 inside the air outlet 110, thereby expanding the air sweeping range of the air conditioner cabinet.

[0072] Specifically, in this embodiment, the axis of the pivot shaft 202 is projected onto the wind sweeping plate 201 in a direction perpendicular to the wind sweeping plate 201. The second chamfered portion 221 is located on one side of this projected position, which, in the air discharge state, is upstream in the air discharge direction. The horizontal leading edges of the upper and lower wind sweeping blades 200 are located on the other side of the projected position. The area on one side of this projected position, where the second chamfered portion 221 is located, is completely within the area on the other side where the trailing edges are located.

[0073] like Figure 1-Figure 3 and Figure 5-Figure 8 As shown, optionally, the upper and lower air sweeping blades 200 are further provided with a second protrusion 222 , and the second protrusion 222 is adapted to the second chamfered portion 221 .

[0074] By arranging the second protrusion 222 to be adapted to the second cut corner portion 221 , when the upper and lower air sweeping blades 200 are in the closed state, the second protrusion 222 can make up for the vacancy of the second cut corner portion 221 , thereby achieving relatively complete shielding of the air outlet 110 .

[0075] The second chamfered portions 221 are provided at both ends of the front edge of the second sweeping blade 220, and second raised portions 222 are provided at positions on the remaining upper and lower sweeping blades 200 corresponding to the front edge of the second sweeping blade 220. The second raised portions 222 are adapted to the second chamfered portions 221, meaning that the second raised portions 222 correspond to the second chamfered portions 221 in position, shape, and size. The second raised portions 222 can cover the gap in the second sweeping blade 220 created by the second chamfered portions 221.

[0076] In addition, it should be noted that in the present embodiment, the front edges of each upper and lower air sweeping blade 200 when in a horizontal position extend out of the air outlet 110. In fact, in another implementation method, part of the front edges of a part of the upper and lower air sweeping blades 200 when in a horizontal position may extend out of the air outlet 110. For example, the raised portion of the second air sweeping blade 220 may extend out of the air outlet 110, which may also reduce the local length of the upper and lower air sweeping blades 200 located behind the air outlet 110, thereby helping to reduce the impact on the thickness of the air-conditioning cabinet while increasing the air guide control capability of the outlet airflow.

[0077] like Figure 2 As shown, optionally, the upper and lower air sweeping blades 200 are configured as follows: when rotated to a vertical position, the lower edge of the upper upper and lower air sweeping blade 200 of the two adjacent upper and lower air sweeping blades 200 overlaps the front side of the upper edge of the lower upper and lower air sweeping blade 200.

[0078] When the upper and lower air sweep blades 200 close the air outlet 110, the air sweep plate 201 is located in front of the pivot shaft 202. Therefore, the gravity acting on the air sweep plate 201 causes a rotational torque on the upper and lower air sweep blades 200. This torque causes the upper edge of the air sweep plate 201 to move toward the rear side of the air outlet 110, while the upper edge of the air sweep plate 201 is now toward the front side of the air outlet 110. This arrangement can utilize the forward movement of the upper edge of the upper and lower air sweep blades 200 to suppress the rearward movement of the lower edge of the upper and lower air sweep blades 200, thereby achieving stability of the upper and lower air sweep blades 200 when closing the air outlet 110.

[0079] like Figure 2 As shown, optionally, a sub-mouth sealing structure is provided between any two adjacent upper and lower sweeping blades 200 , and the sub-mouth sealing structure includes overlapping ridges 230 respectively provided on opposite edges of the adjacent upper and lower sweeping blades 200 .

[0080] With this arrangement, when the upper and lower air sweeping blades 200 are in a vertical position, the gap between any two upper and lower air sweeping blades 200 is blocked by the sub-mouth sealing structure formed by the overlapping ridges 230, preventing dust in the air from entering through the long gaps between the two adjacent upper and lower air sweeping blades 200.

[0081] Specifically, in this embodiment, when the upper and lower air sweep blades 200 are in the closed position, the overlapping rib 230 provided on the upper one of the two adjacent upper and lower air sweep blades 200 is located in front of the overlapping rib 230 of the other. More specifically, the opposing surfaces of the two overlapping ribs 230 are both inclined surfaces, and the opposing surfaces of the overlapping ribs 230 are inclined from bottom to top and rearward.

[0082] Example 2:

[0083] The second embodiment further provides an air conditioner, comprising an outdoor air conditioner and a cabinet air conditioner. The outdoor air conditioner is connected to the cabinet air conditioner via a refrigerant connecting pipe. The cabinet air conditioner comprises any of the cabinet air supply mechanisms described above.

[0084] By arranging the above-mentioned cabinet air supply mechanism in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned cabinet air supply mechanism, which will not be described in detail here.
