Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning sweeping device and an air conditioner. Background Art

[0002] With economic development, air conditioners are becoming increasingly common. Air conditioners typically consist of an indoor unit and an outdoor unit. Due to the airflow from the indoor unit, the sweeping blades of the sweeping mechanism can accumulate dirt after prolonged use. While users can achieve a degree of cleanliness by wiping the surface of the sweeping blades, since the sweeping mechanism is difficult to remove from the indoor unit, this cleaning is limited to simple, localized wiping, making thorough cleaning difficult. Summary of the Invention

[0003] The first object of the present invention is to provide an air-conditioning sweeping device to solve the technical problem that the existing air-conditioning sweeping device is difficult to disassemble.

[0004] The air-conditioning wind sweeping device provided by the present invention includes a middle frame, a wind sweeping mechanism and a driving mechanism. The middle frame is constructed to be fixedly connected to the air-conditioning body, the driving mechanism is detachably connected to the wind sweeping mechanism, the driving mechanism is installed on the middle frame, and the wind sweeping mechanism is detachably connected to the middle frame.

[0005] The air-conditioning sweeping device of the present invention is implemented by fixing a middle frame to the air-conditioning body, installing a driving mechanism on the middle frame, and detachably connecting the sweeping mechanism to the middle frame and the driving mechanism to the sweeping mechanism. When the sweeping mechanism of the air-conditioning needs to be cleaned, the sweeping mechanism can be removed from the air-conditioning and taken out, thereby comprehensively and thoroughly cleaning various components on the sweeping mechanism, more thoroughly removing dirt, reducing the possibility of odor in the air blowing of the air-conditioning indoor unit or reducing the odor, and improving user experience.

[0006] In a preferred technical solution, the wind sweeping mechanism includes a blade mounting plate, and the middle frame includes a middle frame body, a clamping assembly, and a positioning assembly. The clamping assembly and the positioning assembly are both mounted on the middle frame body, and the blade mounting plate is adjacent to the positioning assembly and the middle frame body, and the blade mounting plate is fixed by the clamping assembly. By utilizing the positioning assembly to be adjacent to the blade mounting plate, precise positioning of the blade mounting plate can be achieved, thereby facilitating improved transmission accuracy and reduced energy loss during transmission. At the same time, the clamping assembly is used to fix the blade mounting plate. When the blade mounting plate needs to be removed from the middle frame body, the clamping assembly can be opened, and the blade mounting plate can be detached from the middle frame body. Resetting the clamping assembly can achieve clamping and fixation of the blade mounting plate.

[0007] In a preferred technical solution, the positioning assembly includes a positioning block located in the middle of the middle frame body; a positioning notch is provided in the middle of one side edge of the blade mounting plate, the positioning notch and the positioning block being bidirectionally adjacent in the length direction of the blade mounting plate, and the positioning notch and the positioning block being unidirectionally adjacent in the width direction of the blade mounting plate. This allows for bidirectional positioning of the blade mounting plate in its length direction, preventing movement along the length direction. The positioning block and the positioning notch being unidirectionally adjacent in the width direction of the blade mounting plate not only ensure the relative position of the blade mounting plate with respect to the middle frame body in the width direction, but also allows for separation of the blade mounting plate from the middle frame body, facilitating removal of the blade mounting plate from the middle frame body.

[0008] In a preferred technical solution, the positioning assembly includes a positioning block and a positioning pressure plate. The positioning pressure plate is connected to the middle frame body via the positioning block. The positioning pressure plate is adjacent to a first side of the blade mounting plate, and the middle frame body is adjacent to a second side of the blade mounting plate. The first side and the second side are opposite sides in the thickness direction of the blade mounting plate. The positioning pressure plate can cooperate with the middle frame body to limit the blade mounting plate in the thickness direction, thereby preventing the blade mounting plate from shaking at the positioning notch.

[0009] In a preferred embodiment, the clamping assembly includes an elastic pressure plate having a connecting end and a movable end. The connecting end is connected to the middle frame body, and the movable end is movable relative to the middle frame body. The movable end and the middle frame body are located on opposite sides of the blade mounting plate. When the blade mounting plate needs to be removed or assembled, the movable end can be opened to no longer apply pressure to the blade mounting plate, allowing the blade mounting plate to be separated from the middle frame body. When disassembly or assembly is no longer necessary, the movable end can be released, making operation simple and convenient.

[0010] In a preferred embodiment, the blade mounting plate is provided with a positioning hole; the elastic pressure plate further includes an embedding portion, which protrudes from the movable end toward the middle frame body; and the embedding portion is embedded in the positioning hole. Leveraging the elasticity of the elastic pressure plate, the embedding portion can be embedded in the positioning hole of the blade mounting plate when the blade mounting plate is installed in the middle frame body. Unless the elastic pressure plate is further opened, the embedding portion will not disengage from the positioning hole under normal conditions, thereby improving the reliability of the blade mounting plate installation.

[0011] In a preferred technical solution, the surface of the embedded portion facing the connection end is an inclined surface. During the process of installing the blade mounting plate on the middle frame body, as the elastic pressure plate returns to its spontaneous state, this inclined surface is used to apply a force toward the connection end of the elastic pressure plate to the wall of the positioning hole, thereby reducing the need for manual thrust and lowering labor intensity.

[0012] In a preferred embodiment, the movable end further comprises a lifting portion, the distance between the lifting portion and the middle frame body gradually increasing as the distance away from the connecting end is moved. When the elastic pressure plate is opened, a finger can be inserted between the lifting portion and the leaf middle frame body to lift the lifting portion, thereby freeing the movable end from pressing against the blade mounting plate or the middle frame body, thereby allowing the blade mounting plate to be removed.

[0013] In a preferred technical solution, the wind sweeping mechanism further includes a wind sweeping blade; the blade mounting plate includes a mounting plate body, the mounting plate body protruding along the thickness direction of the blade mounting plate, and the wind sweeping blade is mounted on the mounting plate body; the middle frame body includes a positioning groove, and the sidewalls of the mounting plate body are adapted to the sidewalls of the positioning groove. The protruding mounting plate body is provided on the blade mounting plate, and the sidewalls of the mounting plate body are adapted to the sidewalls of the positioning groove of the middle frame body. The contact between the sidewalls of the mounting plate body and the positioning groove allows the blade mounting plate to bear a portion of the load perpendicular to its thickness. This not only reduces the possibility of damage to the positioning block, but also helps reduce wear on the elastic pressure plate, thereby increasing its service life.

[0014] The second object of the present invention is to provide an air conditioner to solve the technical problem that the air-conditioning sweeping device in the existing air conditioner is difficult to disassemble.

[0015] The air conditioner provided by the present invention includes the above-mentioned air-conditioning sweeping device.

[0016] By arranging the above-mentioned air-conditioning sweeping device in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned electric control box assembly, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is given in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] Figure 1 A schematic structural diagram of an air-conditioning sweeping device provided in an embodiment of the present invention; Figure 2 for Figure 1 The three-dimensional cross-sectional view of the air-conditioning sweeping device shown is viewed from another angle; Figure 3 for Figure 1 The schematic diagram of the state of the air sweeping mechanism of the air conditioner air sweeping device after being separated from the middle frame; Figure 4 for Figure 3 A schematic diagram of the air-conditioning sweeping device in the illustrated state viewed from another angle; Figure 5 for Figure 3 Schematic diagram of the state of the air-conditioning sweeping device after the sweeping box, blade mounting plate, sweeping blades, sweeping connecting rod and middle frame are separated; Figure 1-Figure 5 As shown, the air-conditioning sweeping device provided by the present invention includes a middle frame 200, a sweeping mechanism and a driving mechanism 300. The middle frame 200 is constructed to be fixedly connected to the air-conditioning body, and the driving mechanism 300 is detachably connected to the sweeping mechanism. The driving mechanism 300 is installed on the middle frame 200, and the sweeping mechanism is detachably connected to the middle frame 200.

[0052] The air-conditioning air-sweeping device is configured such that a middle frame 200 is fixedly connected to the air-conditioning body, a driving mechanism 300 is installed on the middle frame 200, the air-sweeping mechanism is detachably connected to the middle frame 200, and the driving mechanism 300 is detachably connected to the air-sweeping mechanism. When the air-sweeping mechanism of the air-conditioning needs to be cleaned, the air-sweeping mechanism can be removed from the air-conditioning and taken out, thereby comprehensively and thoroughly cleaning various components on the air-sweeping mechanism, more thoroughly removing dirt, reducing the possibility of odor in the air blown by the air-conditioning indoor unit or reducing the odor, thereby improving user experience.

[0053] Figure 6 A cross-sectional view of the air-conditioning sweeping device provided by an embodiment of the present invention, taken at the elastic pressure plate; Figure 7 for Figure 6 A partial enlarged view of part A. Figure 6 and Figure 7 As shown, preferably, the wind sweeping mechanism includes a blade mounting plate 100, the middle frame 200 includes a middle frame body 210, a clamping assembly and a positioning assembly 230, the clamping assembly and the positioning assembly 230 are both installed on the middle frame body 210, the blade mounting plate 100 is adjacent to the positioning assembly 230 and the middle frame body 210, and the blade mounting plate 100 is fixed by the clamping assembly.

[0054] By utilizing the positioning assembly 230 in contact with the blade mounting plate 100, the blade mounting plate 100 can be precisely positioned, thereby enabling the wind sweeping blades 400 to be more accurately positioned, thereby improving transmission accuracy and reducing energy loss during transmission. A clamping assembly is also used to secure the blade mounting plate 100. When the blade mounting plate 100 needs to be removed from the middle frame body 210, the clamping assembly can be opened to release the blade mounting plate 100. Resetting the clamping assembly secures and secures the blade mounting plate 100.

[0055] Among them, the blade mounting plate 100 is roughly rectangular, and the blade mounting plate 100 includes a connecting side plate portion 120 and a mounting plate body portion 110, wherein the connecting side plate portion 120 is located at one long side and two short sides of the rectangle, and the portion that has a positioning relationship with the positioning component 230 and is clamped by the clamping component is mainly the connecting side plate portion 120, while the mounting plate body portion 110 is mainly used to install the wind sweeping blade 400.

[0056] Figure 8 A three-dimensional cross-sectional view of the air sweeping mechanism in the air-conditioning air sweeping device provided in an embodiment of the present invention; Figure 8 As shown, in addition, the air sweeping mechanism further includes an air sweeping box 600, which is mounted on the blade mounting plate 100. The air sweeping box 600 is provided to shield the air sweeping connecting rod 500, thereby reducing the speed at which air passes through the air sweeping connecting rod 500 and attaches dirt to the air sweeping connecting rod 500.

[0057] Figure 9 is a three-dimensional cross-sectional view of an air-conditioning sweeping device provided by an embodiment of the present invention, viewed at a positioning component; Figure 10 for Figure 9 A partial enlarged view of part B. Figure 9 and Figure 10 As shown, preferably, the positioning assembly 230 includes a positioning block 231, which is located in the middle of the middle frame body 210; a positioning notch 121 is provided in the middle of one side edge of the blade mounting plate 100, and the positioning notch 121 and the positioning block 231 are adjacent to each other in both directions in the length direction of the blade mounting plate 100, and the positioning notch 121 and the positioning block 231 are adjacent to each other in one direction in the width direction of the blade mounting plate 100.

[0058] By providing bidirectional abutment between the positioning block 231 and the positioning notch 121 along the length of the blade mounting plate 100, the blade mounting plate 100 can be positioned bidirectionally along its length, preventing longitudinal movement. Furthermore, the positioning block 231 and the positioning notch 121 are unidirectionally abutted along the width of the blade mounting plate 100, ensuring the relative position of the blade mounting plate 100 with respect to the middle frame body 210 along the width direction. Furthermore, the blade mounting plate 100 and the middle frame body 210 can be separated from each other, facilitating removal of the blade mounting plate 100 from the middle frame body 210.

[0059] Specifically, the positioning notch 121 is located at the edge of the connecting side plate portion 120 facing the interior of the middle frame body 210. The positioning notch 121 can be formed by two notch limiting plates 122 protruding from the connecting side plate portion 120. The two notch limiting plates 122 are pentagons formed by cutting off only one corner of a rectangle. The two notch limiting plates 122 are symmetrically arranged, and the cut-off corners are arranged facing each other and away from the middle frame body 210. The roots of the two notch limiting plates 122 and the side edges of the connecting side plate portion 120 together form a rectangular notch. When the blade mounting plate 100 is in the installed state, the positioning block 231 is stuck in the rectangular notch. The cut-off corners of the two notch limiting plates 122 can be open-shaped, with the outside larger and the inside smaller, where the inside refers to the direction closer to the rectangular notch. This arrangement can play a guiding role when the blade mounting plate 100 is installed on the middle frame body 210, so as to facilitate the positioning block 231 to move relatively more smoothly into the rectangular notch, thereby improving the convenience of installation.

[0060] like Figure 9 and Figure 10As shown, preferably, the positioning assembly 230 further includes a positioning pressure plate 232, which is connected to the middle frame body 210 through a positioning block 231. The positioning pressure plate 232 is adjacent to the first side of the blade mounting plate 100, and the middle frame body 210 is adjacent to the second side of the blade mounting plate 100. The first side and the second side are opposite sides in the thickness direction of the blade mounting plate 100. Figure 1 The lower side of the blade mounting plate 100 is shown as the second side. Figure 1 The upper side of the blade mounting plate 100 is shown.

[0061] By providing a positioning pressure plate 232 connected to the middle frame body 210 through a positioning block 231, the positioning pressure plate 232 can cooperate with the middle frame body 210 to jointly limit the blade mounting plate 100 in the thickness direction of the blade mounting plate 100, thereby preventing the blade mounting plate 100 from shaking at the positioning notch.

[0062] like Figure 6 and Figure 7 As shown, preferably, the clamping assembly includes an elastic pressure plate 220, which has a connecting end and a movable end. The connecting end is connected to the middle frame body 210, and the movable end can move relative to the middle frame body 210, and the movable end and the middle frame body 210 are located on opposite sides of the blade mounting plate 100.

[0063] By providing the elastic pressure plate 220, when the blade mounting plate 100 needs to be disassembled, the movable end can be opened so that it no longer applies pressure to the blade mounting plate 100, allowing the blade mounting plate 100 to be separated from the middle frame body 210. When disassembly is not required, the movable end can be released, making the operation simple and convenient.

[0064] Specifically, the elastic pressure plate 220 can be roughly in the shape of an inverted L, with the connecting end being the vertical end of the inverted L connected to the middle frame body 210, and the movable end being the horizontal end of the inverted L, away from the connecting end. Because the elastic pressure plate 220 is not an absolutely rigid body and is only fixedly connected to the middle frame body 210 at its connecting end, the elastic pressure plate 220 is easily deformed when a force is applied perpendicular to the middle frame body 210 at the movable end. Therefore, it is referred to as the elastic pressure plate 220.

[0065] like Figure 7 As shown, preferably, the connecting side plate portion 120 is provided with a positioning hole 123 ; the elastic pressure plate 220 further includes an embedding portion 221 , which protrudes from the movable end toward the middle frame body 210 ; the embedding portion 221 is embedded in the positioning hole 123 .

[0066] By providing an embedding portion 221 at the movable end and utilizing the elasticity of the elastic pressure plate 220 itself, when the connecting side plate portion 120 is installed on the middle frame body 210, the embedding portion 221 can be embedded in the positioning hole 123 of the connecting side plate portion 120. Unless the elastic pressure plate 220 is opened again, the embedding portion 221 will not be separated from the positioning hole 123 under normal conditions, thereby improving the reliability of the installation of the blade mounting plate 100.

[0067] Specifically, the positioning holes 123 can be located on the two shorter sides connecting the side plate portions 120, and at the corner of the two corners of the side that is farther from the positioning notch 121. The positioning holes 123 and the positioning notch 121 form a triangular three-point positioning arrangement, thereby firmly securing the blade mounting plate 100 to the middle frame body 210.

[0068] like Figure 7 As shown, preferably, the surface of one side of the embedded portion 221 facing the connection end is an inclined surface.

[0069] This side surface of the embedded portion 221 is set as a slope. During the process of installing the blade mounting plate 100 on the middle frame body 210 and the process of the elastic pressure plate 220 restoring its spontaneous state, this slope is used to apply a force toward the connection end of the elastic pressure plate 220 to the wall of the positioning hole 123, thereby reducing the thrust that needs to be provided manually and reducing labor intensity.

[0070] Specifically, the cross section of the embedded portion 221 is a right-angled trapezoid, and the hypotenuse of the right-angled trapezoid is the edge of the side facing the connection end.

[0071] like Figure 7 As shown, preferably, the movable end further has a lifting portion 222 , and the distance between the lifting portion 222 and the middle frame body 210 gradually increases in the direction away from the connection end.

[0072] By providing the lifting portion 222, when opening the elastic pressure plate 220, one can insert one's finger between the lifting portion 222 and the leaf middle frame body 210, and lift up the lifting portion 222, so that the movable end no longer presses the blade mounting plate 100 or the middle frame body 210, thereby allowing the blade mounting plate 100 to be disassembled and assembled.

[0073] In addition to the above-mentioned solution in which the lifting portion 222 gradually moves away from the middle frame body 210, the lifting portion 222 can also be in the form of extending out of the blade mounting plate 100. When the extended portion is lifted by a finger, the pressure of the movable end on the blade mounting plate 100 can also be released. However, this solution will cause components to protrude beyond the edge of the blade mounting plate 100, which may affect the layout of other components.

[0074] like Figure 2-Figure 5As shown, preferably, the wind sweeping mechanism also includes a wind sweeping blade 400; the mounting plate body 110 protrudes along the thickness direction of the blade mounting plate 100, and the wind sweeping blade 400 is installed on the mounting plate body 110; the middle frame body 210 includes a positioning groove 240, and the side wall of the mounting plate body 110 is adapted to the side wall of the positioning groove 240.

[0075] The blade mounting plate 100 is provided with a raised mounting plate body 110. The sidewalls of the mounting plate body 110 mate with the sidewalls of the positioning slot 240 of the middle frame body 210. The contact between the sidewalls of the mounting plate body 110 and the positioning slot 240 allows the blade mounting plate 100 to bear a portion of the load perpendicular to its thickness. This not only reduces the possibility of damage to the positioning block 231, but also helps reduce wear on the elastic pressure plate 220, thereby increasing its service life. Furthermore, the structure of embedding the mounting plate body 110 in the positioning slot 240 allows the middle frame body 210 and the blade mounting plate 100 to have a wall thickness of only one layer over most of their area, reducing material consumption and the weight of the air conditioner.

[0076] Specifically, the positioning groove 240 may be rectangular, and the mounting plate body 110 may also be rectangular, and the rectangular shape of the mounting plate body 110 and the rectangular shape of the positioning groove 240 are the same in size.

[0077] Figure 11 It is a partial three-dimensional schematic diagram of the air sweeping blades in the above-mentioned air-conditioning air sweeping device installed on the air sweeping mounting plate; Figure 12 A three-dimensional cross-sectional view of the swept air blade installed on the swept air mounting plate viewed from another angle; Figure 13 This is a structural schematic diagram of the air-sweeping blades in the air-conditioning sweeping device as viewed from another angle, mounted on the sweeping mounting plate; Figure 14 A partial schematic diagram of the air sweeping blades in the above-mentioned air-conditioning air sweeping device; Figure 15 This is a schematic structural diagram of the blade mounting plate in the above-mentioned air-conditioning sweeping device; Figure 16 for Figure 15 A partial enlarged view of part C;

[0079] like Figures 11-18As shown, preferably, the wind sweeping blade 400 is rotatably connected to the blade mounting plate 100. The wind sweeping blade 400 includes a blade body 450 and an eccentrically arranged guide post 420. The guide post 420 extends away from the blade body 450 along the rotation axis of the wind sweeping blade 400. A positioning protrusion 430 extends radially outward from the sidewall of the guide post 420. The blade mounting plate includes a track groove 112 and a positioning recess 114 connected to the track groove 112. The positioning recess 114 is radially recessed in the sidewall of the track groove 112 and allows the positioning protrusion 430 to pass through. That is, the radial and circumferential dimensions of the positioning protrusion 430 about the rotation axis are smaller than or equal to the dimensions of the positioning recess 114. The positioning protrusion 140 can extend into the positioning recess 114, and during the rotation of the wind sweeping blade 400, the guide post 230 can slide along the track groove 112.

[0080] It should be noted that the rotation axis is a virtual line, not a line with a solid volume or a line formed by the intersection of two surfaces.

[0081] By providing a track slot 112 on the blade mounting plate 100 and inserting a guide post 420 through the track slot 112, the track slot 112 can guide the movement of the guide post 420. The positioning protrusion 430 can extend into the positioning recess 114. When the positioning protrusion 430 rotates with the positioning post 220, it can rotate to the first side of the sidewall of the track slot 112, thereby axially positioning the wind sweeping blade 400 relative to the blade mounting plate 100. To remove the wind sweeping blade 400 from the blade mounting plate 100, the wind sweeping blade 400 can be rotated until the positioning protrusion 430 is aligned with the positioning recess 114. The wind sweeping blade 400 can then be withdrawn along the direction of the rotation axis, thereby conveniently removing and assembling the wind sweeping blade 400. This helps the user to separate the sweeping blades 400 separately after removing the sweeping assembly and perform special cleaning, which can more thoroughly remove dirt, reduce the possibility of odor in the air blowing of the air conditioner indoor unit or reduce the odor, and improve the user experience.

[0082] Specifically, the track slot 112 penetrates the blade mounting plate 100 in the thickness direction and can be an arc-shaped hole. The axis along the thickness direction of the blade mounting plate 100 where the center of the arc is located is the rotation axis.

[0083] Specifically, the positioning protrusion 430 can be a radially protruding portion of the guide column 420, for example, it can be a plate or a protruding column or rod. As long as it can be located below the first positioning plate 113, it can work together with the second positioning plate 410 to axially position the wind-sweeping blade 400.

[0084] like Figure 11-13 and Figure 16-Figure 18As shown, preferably, the blade mounting plate 100 also includes a first positioning plate 113, the track groove 112 extends circumferentially along the rotation axis of the relative rotation between the wind sweeping blade 400 and the blade mounting plate 100, the first positioning plate 113 and the positioning recess 114 are arranged on the side of the track groove 112 facing the rotation axis, and the positioning protrusion 430 is arranged on the side of the guide column 420 facing the rotation axis.

[0085] Positioning the positioning recess 114 and the positioning protrusion 430 on the side facing the rotation axis can reduce the impact range of the slots on the blade mounting plate 100, thereby reducing the negative impact of the slots on the strength and rigidity of the blade mounting plate 100. In other words, while maintaining the same strength and rigidity, the material usage of the blade mounting plate 100 can be reduced, thereby reducing the manufacturing cost and weight of the air conditioner.

[0086] Specifically, for example, the track groove 112 has a central angle of 150° relative to the rotation axis, then the side wall of the 130° area in the track groove 112 is formed by the side wall of the first positioning plate 113, and the remaining 20° side wall is formed by the side wall of the positioning recess 114 that is closer to the rotation axis.

[0087] like Figure 11 、 Figure 12 、 Figure 16 and Figure 18 As shown, preferably, the wind sweeping blade 400 also includes a second positioning plate 410, and the blade body 450 and the guide column 420 are connected through the second positioning plate 410, wherein the blade body 450 and the guide column 420 are respectively located on opposite sides of the second positioning plate 410; the blade mounting plate 100 also includes a locking protrusion 117, and the locking protrusion 117 is arranged on the second side of the mounting plate body 110, and the edge of the second positioning plate 410 is provided with an unlocking recess 411. When the positioning protrusion 430 is aligned with the positioning recess 114, the unlocking recess 411 is aligned with the locking protrusion 117, and the locking protrusion 117 is used to pass through the unlocking recess 411, that is, the radial and circumferential dimensions of the locking protrusion 117 in the rotation axis are less than or equal to the dimensions of the unlocking recess 411.

[0088] The locking protrusion 117 is provided so that the second positioning plate 410 can be axially limited by the locking protrusion 117 and the mounting plate body 110, thereby preventing the sweeping blade 400 from relative axial movement with the blade mounting plate 100. This provides a double guarantee for the axial positioning of the sweeping blade 400 and the blade mounting plate 100, thereby improving the reliability of the operation of the sweeping device. When the sweeping blade 400 needs to be removed from the blade mounting plate 100, the sweeping blade 400 is rotated until the unlocking recess 411 is aligned with the locking protrusion 117, and the positioning protrusion 430 is also aligned with the positioning recess 114. The sweeping blade 400 can then move axially with the blade mounting plate 100, thereby achieving separation of the sweeping blade 400 from the blade mounting plate 100.

[0089] Specifically, the mounting plate body 110 can be provided with multiple countersunk holes, with each second positioning plate 410 accommodated in a countersunk hole. The second side surface of the second positioning plate 410 is flush with the surface of the mounting plate body 110 outside the countersunk hole. The locking protrusion 117 is fixedly connected to the second side of the mounting plate body 110 and extends into the area on the second side of the countersunk hole. The unlocking recess 411 can be a rectangular notch provided on the edge of the second positioning plate 410.

[0090] like Figure 11 、 Figure 12 、 Figure 16 and Figure 18 As shown, preferably, the blade mounting plate 100 also includes a center column 116, and the wind sweeping blade 400 also includes a positioning sleeve portion 440, which is located on the second side of the mounting plate body 110, and the positioning sleeve portion 440 is rotatably connected to the center column 116, and the rotation axis coincides with the center line of the center column 116.

[0091] By providing the center post 116 and rotatably connecting the positioning sleeve portion 440 to the center post 116, the center post 116 can be used to directly position the rotation of the sweeping blade 400, thereby improving the movement accuracy of the sweeping blade 400. Furthermore, when removing the sweeping blade 400 from the blade mounting plate 100, the stability of the sweeping blade 400 during axial movement is improved, preventing the sweeping blade 400 from tilting, reducing the possibility of the second positioning plate 410 getting stuck with other parts, and improving removal speed.

[0092] Specifically, a tapered portion may be provided at the top of the center column 116, and a countersunk hole may be provided at the bottom of the center column 116. The countersunk hole is located inside the center column 116. This setting can make the thickness of each part of the center column 116 more uniform, and the center column 116 will not have processing defects due to excessive thickness of local material during processing such as injection molding.

[0093] Figure 19It is a partial schematic diagram of the connection between the guide column and the air sweeping connecting rod in the above-mentioned air-conditioning air sweeping device; Figure 20 It is a partial three-dimensional cross-sectional view of the connection between the guide column and the air sweeping connecting rod in the above-mentioned air-conditioning air sweeping device; Figure 21 Schematic diagram of the partial structure of the air sweep connecting rod in the above-mentioned air-conditioning sweeping device; Figures 19-21 As shown, preferably, it also includes a wind sweeping link 500, which is provided with a blade connecting hole 530, and the guide column 420 also has a constricted portion 421, which is located on the first side of the positioning protrusion 430; the constricted portion 421 passes through the blade connecting hole 530, and the first side of the constricted portion 421 is provided with a limiting protrusion 422, the diameter of the limiting protrusion 422 is larger than the constricted portion 421, and the limiting protrusion 422 is located on the first side of the wind sweeping link 500.

[0094] By providing a constricted portion 421 on the guide post 420 for connection to the air sweep link 500, and providing a stopper protrusion 422 having a larger diameter than the constricted portion 421 on the first side of the constricted portion 421, the guide post 420 can bear part of the weight of the air sweep link 500. This eliminates the need for the air sweep link 500 to be directly supported by the air sweep box 600, and also avoids wear and tear caused by contact and relative movement between the air sweep link 500 and the air sweep box 600. Even if the relative movement between the air sweep link 500 and the guide post 420 causes damage to the guide post 420, only the corresponding air sweep blade 400 needs to be replaced, reducing maintenance costs.

[0095] In addition, by using an eccentrically arranged guide column 420 as the connection part between the sweeping blade 400 and the sweeping connecting rod 500, there is no need to set up a connecting rod or crank separately. While the second positioning plate 410 completes the positioning of the sweeping blade 400, the transmission connection of the sweeping blade 400 can also be realized, reducing the processing difficulty of the sweeping blade 400.

[0096] Specifically, an annular groove is formed radially outwardly of the constricted portion 421. Both sidewalls of the annular groove are annular surfaces perpendicular to the axis of the guide post 420. These two annular surfaces are adjacent to the thickness-direction side surfaces of the wind sweeping link 500. Since neither the guide post 420 nor the wind sweeping link 500 is an absolutely rigid body, during the insertion of the guide post 420 into the wind sweeping link 500, a significant external force can be applied to compress the stopper protrusion 422 and / or open the blade connection hole 530, allowing the guide post 420 to be inserted into or removed from the wind sweeping link 500.

[0097] In order to further reduce the resistance of the guide column 420 when inserted into the wind sweeping link 500, the end of the limiting protrusion 422 facing away from the neck portion 421 can be set as a frustum-shaped guide portion. In the spontaneous state, the diameter of the top of the frustum-shaped guide portion is smaller than the diameter of the blade connecting hole 310 in the spontaneous state, so as to facilitate the insertion of the smaller diameter end of the frustum-shaped guide portion into the blade connecting hole 310 first, thereby facilitating the use of the frustum-shaped guide portion and the blade connecting hole 310 to force the other party to deform, and finally insert the guide column 420.

[0098] like Figures 19-21 As shown, preferably, the wind sweeping connecting rod 500 is further provided with an expansion joint 540 , and the expansion joint 540 is arranged along the radial direction of the blade connecting hole 530 .

[0099] By providing the expansion joint 540, the material on both sides of the blade connection hole 310 can expand outward during the process of the guide column 420 being inserted into or separated from the wind sweeping link 500, thereby achieving a detachable connection between the guide column 420 and the wind sweeping link 500. It can also appropriately reduce the movement resistance of the guide column 420 and the wind sweeping link 500 along the thickness direction of the wind sweeping link 500, thereby reducing the workload during assembly and disassembly. Because the size of the limiting protrusion 422 of the guide column 420 is smaller than the size of the expansion joint 540, even if the same proportion of deformation occurs, the deformation of the limiting protrusion 422 is not large. The provision of the expansion joint 540 on the wind sweeping link 500 helps to separate the material on both sides of the expansion joint 540 by a greater distance, thereby expanding the blade connection hole 310 to accommodate the limiting protrusion 422.

[0100] More specifically, the expansion joints 540 on both sides of the blade connection hole 310 are symmetrically arranged.

[0101] like Figures 19-21 As shown, preferably, the expansion joint 540 extends along the length direction of the wind sweeping link 500 .

[0102] The expansion joint 540 is extended along the length direction of the wind sweeping link 500. Even if the length of the expansion joint 540 is increased, the width of the wind sweeping link 500 will not be significantly increased, thereby appropriately weakening the stiffness of the wind sweeping link 500 material on both sides of the expansion joint 540, making it easier for the guide column 420 to be inserted or removed.

[0103] If the expansion gap 540 extends along the width of the wind sweeping link 500, the expansion gap 540 needs to be longer to ensure that the blade connection hole 310 can expand to a larger extent to allow the limiting protrusion 422 to pass through. If such an expansion gap 540 is provided, the width of the wind sweeping link 500 will be increased in some areas, which not only wastes material but also has a negative impact on the layout of other components. Moreover, in this case, the outside of the expanded material is also surrounded by other materials of the wind sweeping link 500, which also hinders the expansion gap 540 from being expanded.

[0104] Figure 22 is a partial schematic diagram of the air sweeping drive mechanism in the above-mentioned air-conditioning air sweeping device; Figure 23 yes Figure 22 The partial schematic diagram of the wind sweeping drive mechanism shown is viewed from another angle.

[0105] like Figure 21-23 As shown, preferably, the wind sweeping drive mechanism includes a first transmission member 320, the wind sweeping mechanism includes a wind sweeping connecting rod 500, and the first transmission member 320 includes a transmission protrusion 321; the wind sweeping connecting rod 500 includes a accommodating space 510 and an opening portion 520, the accommodating space 510 accommodates the transmission protrusion 321, and is used to drive the wind sweeping connecting rod 500 to move along the length direction of the wind sweeping connecting rod 500 when abutted by the transmission protrusion 321; the opening portion 520 connects the side wall surface of the wind sweeping connecting rod 500 and the accommodating space 510, so that the transmission protrusion 321 can move away from the accommodating space 510 when it detaches from the wind sweeping connecting rod 500. In this embodiment, the accommodating space 510 and the opening 520 can form a slide groove, one end of which has a notch on the side surface of the wind sweeping link 500. The transmission protrusion 321 can slide in the slide groove when driving the wind sweeping link 500 to move along the length direction. The wind sweeping link 500 is disengaged from the first transmission member 320 by the relative sliding of the transmission protrusion 321 and the wind sweeping link 500 in the slide groove.

[0106] By providing an opening 520 to connect the accommodating space 510 and the side surface of the wind sweeping link 500, when the wind sweeping mechanism is removed, the transmission protrusion 321 of the first transmission member 320 can move relative to the wind sweeping link 500, pass through the opening 520, and finally separate from the wind sweeping link 500, that is, the wind sweeping link 500 is removed from the first transmission member 320. When the first transmission assembly and the wind sweeping link 500 are connected, the transmission protrusion 321 can drive the wind sweeping link 500 to move.

[0107] Thus, when removing the purge mechanism, there is no need to remove the drive motor 340 that drives the purge. Simply separating the purge connecting rod 500 and the first transmission member 320 allows the purge mechanism to be separated from the purge drive mechanism, thereby improving the convenience of disassembling the purge mechanism. This facilitates a more comprehensive and thorough cleaning of the various components of the purge mechanism after removal, reducing the likelihood of odor from the air blown by the air conditioner indoor unit or mitigating odor, thereby improving the user experience.

[0108] like Figure 22 and Figure 23 As shown, specifically, in this embodiment, the first transmission member 320 can be a disc-shaped part, and the transmission protrusion 321 can be a transmission column provided on the end surface of the disc-shaped part and protruding along the thickness direction of the disc-shaped part - the axis of rotation of the first rotating member 200. During the transmission process, the transmission column abuts against the side wall of the accommodating space 510, thereby driving the wind sweeping link 500 to perform corresponding movement. In another implementation, as long as it protrudes from the end surface of the first transmission member 320 along the axis of rotation, the transmission protrusion 321 can be a protruding hemispherical or circular shape, as long as it can be partially or completely accommodated in the accommodating space 510. When transmission is required, it can abut against the side wall of the accommodating space 510 and apply a force to the wind sweeping link 500 to drive the wind sweeping link 500 to move.

[0109] Alternatively, the first transmission member 320 may be a rod-shaped component, one end of which is fixedly connected to the output shaft of the drive motor 340, and the other end of which is a free end that swings. The transmission protrusion 321 may be disposed near the free end of the rod-shaped component and protrude from the surface of the rod-shaped component along the axis of the rod-shaped component's swing.

[0110] like Figure 21 As shown, preferably, the accommodating space 510 includes a first side wall 511 and a second side wall 512. The first side wall 511 and the second side wall 512 are arranged opposite each other. When the transmission protrusion 321 drives the wind sweeping link 500 to move along the first radial direction, the first side wall 511 abuts against the transmission protrusion 321; when the transmission protrusion 321 drives the wind sweeping link 500 to move along the second radial direction, the second side wall 512 abuts against the transmission protrusion 321. The first radial direction and the second radial direction are both parallel to the length direction of the wind sweeping link 500. The first radial direction is the direction in which the wind sweeping link 500 moves from the position where it is connected to the wind sweeping blade 400 to the first transmission member 320, and the second radial direction is opposite to the first radial direction.

[0111] By respectively providing the first side wall 511 and the second side wall 512 , the transmission protrusion 321 can drive the wind sweeping link 500 to move along the first radial direction or the second radial direction when abutting against the first side wall 511 and the second side wall 512 , thereby enabling the wind sweeping link 500 to drive the wind sweeping blade 400 to swing.

[0112] Specifically, the first side wall 511 and the second side wall 512 are both plane and arranged in parallel, and correspondingly, the transmission column serving as the transmission protrusion 321 can be cylindrical in the portion located in the accommodating space 510. The ends of the first side wall 511 and the second side wall 512 away from the opening 520 can be connected by a semicircular arc, the radius of which is the same as the radius of the transmission column. That is, the accommodating space 510 can be a waist-shaped hole with one end open, and the direction of the opening is the direction of the opening 520. In another implementation, when the transmission process does not require the transmission protrusion 321 to slide relative to the wind sweeping link 500, the accommodating space 510 can also be a circular hole, the side wall of which matches the outer circumference of the transmission protrusion 321, and the extension direction of the circular hole is the thickness direction of the wind sweeping link 500.

[0113] Thus, when the first transmission member 320 drives the transmission protrusion 321 to perform circular motion, the transmission protrusion 321 can not only slide within the accommodation space 510 between the first side wall 511 and the second side wall 512, but can also rotate. Furthermore, the distance between the center of rotation of the transmission protrusion 321 and the first side wall 511 and the second side wall 512 does not change. Therefore, the position of the first side wall 511 and the second side wall 512 in the longitudinal direction of the wind sweeping link 500 can be completely determined by the projected position of the transmission protrusion 321 in that direction, thereby improving transmission accuracy and motion smoothness.

[0114] like Figure 21 As shown, preferably, the opening portion 520 includes a third side wall 521 and a fourth side wall 522, and the third side wall 521 and the fourth side wall 522 are arranged opposite to each other; the third side wall 521 is adjacent to the first side wall 511 and both are located on the same side of the transmission protrusion 321, and the fourth side wall 522 is adjacent to the second side wall 512 and both are located on the same side of the transmission protrusion 321.

[0115] By setting the third side wall 521 and the fourth side wall 522, the side distance between the first side wall 511 and the second side wall 512 and the opening 520 of the wind sweeping link 500 can be increased. When disassembly is not required, the transmission protrusion 321 only moves within the accommodating space 510 and will not fall out from the side of the wind sweeping link 500, thereby improving the reliability of the wind sweeping device during use.

[0116] It should be noted that, in the present application, there is no absolute physical separation between the third side wall 521 and the first side wall 511, and between the fourth side wall 522 and the second side wall 512. Furthermore, it is not necessary that the shape of the third side wall 521 must be different from that of the first side wall 511, or that the two have a clear intersection line, or that the fourth side wall 522 must be different from that of the second side wall 512, or that the two have a clear intersection line. The first side wall 511 and the second side wall 512 may be the partial side walls of the chute corresponding to the sliding area of the transmission protrusion 321; and the third side wall 521 and the fourth side wall 522 may be the portions of the two side walls of the chute other than the first side wall 511 and the second side wall 512.

[0117] like Figure 21 As shown, preferably, the third sidewall 521 includes a first chamfered portion 523, and the fourth sidewall 522 includes a second chamfered portion 524; the distance between the first chamfered portion 523 and the second chamfered portion 524 gradually increases along the direction from the accommodating space 510 toward the opening 520. The third sidewall 521 may include only the first chamfered portion 523 or may also include the area between the first chamfered portion 523 and the first sidewall 511; the fourth sidewall 522 may include only the second chamfered portion 524 or may also include the area between the second chamfered portion 524 and the second sidewall 512.

[0118] By setting the first chamfered portion 523 and the second chamfered portion 524, and making the opening area between the first chamfered portion 523 and the second chamfered portion 524 larger on the outside and smaller on the inside, when the wind sweeping mechanism is installed on the air conditioner, when the wind sweeping link 500 and the transmission protrusion 321 move relative to each other, the first chamfered portion 523 and the second chamfered portion 524 can be used to guide the wind sweeping link 500, driving the wind sweeping link 500 to move in its length direction, so that the opening portion 520 is aligned with the transmission protrusion 321, which facilitates the installation of the wind sweeping link 500 on the transmission protrusion 321.

[0119] like Figure 21 As shown, specifically, in this embodiment, the first chamfered portion 523 and the second chamfered portion 524 are both oblique chamfered portions, and each oblique chamfered portion itself is a flat surface. In other implementations, the first chamfered portion 523 and the second chamfered portion 524 can be arc chamfered portions, or chamfered portions with an edge interface forming a broken line, as long as the condition that the closer to the accommodation space 510, the smaller the distance.

[0120] like Figure 21 As shown, preferably, the accommodating space 510 and the opening 520 extend along the width direction of the wind sweeping link 500 .

[0121] By arranging the accommodating space 510 and the opening 520 to extend in the width direction of the wind sweep link 500, the wind sweep mechanism including the wind sweep link 500 can be disengaged from the middle frame 200 in this direction. Furthermore, this direction provides the shortest distance traveled during disengagement, which helps reduce the length of the disengagement path. In particular, when the wind sweep mechanism is being disassembled, friction is generated by contact between the elastic pressure plate 220 securing the wind sweep mechanism and the blade mounting plate 100. This arrangement reduces the work done by this friction, improving disassembly efficiency and reducing wear on the blade mounting plate 100.

[0122] Figure 24 yes Figure 22 The schematic diagram of the wind sweeping drive mechanism shown is after the drive motor is separated from the first transmission member; Figure 25 This is a schematic diagram of the structure of the first transmission member in the air-conditioning sweeping device provided by an embodiment of the present invention. Figure 22 、 Figure 24 and Figure 25 As shown, preferably, the first transmission member 320 includes a transmission member body and a movable limiting portion 323 , the movable limiting portion 323 protrudes radially from the transmission member body, and the movable limiting portion 323 is used to be limited by the fixed limiting portion 333 to limit the rotation angle of the first transmission member 320 .

[0123] By providing a radially protruding movable limit portion 323 on the transmission member body, the movable limit portion 323 can be restricted by the fixed limit portion 333 to limit the maximum rotation angle of the first transmission member 320, thereby limiting the movement stroke of the wind sweeping link 500, avoiding excessive stroke of the wind sweeping link 500 and the occurrence of a dead point when driving the wind sweeping blade 400 to swing. It is particularly suitable for occasions where the wind sweeping link 500 drives the wind sweeping blade 400 to swing, such as occasions with low movement speed and small kinetic energy of components.

[0124] Specifically, the transmission part body may include an outer annular portion 3221, an inner sleeve portion 3223 and a radial connecting portion 3222, the radial connecting portion 3222 extends outward from the outer surface of the inner sleeve portion 3223 to the inner surface of the outer annular portion 3221, the outer peripheral surface of the outer annular portion 3221 is a cylindrical surface, and the movable limiting portion 323 protrudes from the outer peripheral surface of the outer annular portion 3221.

[0125] like Figure 24 As shown, preferably, the wind sweeping drive mechanism also includes a drive motor 340 and a motor fixing sleeve 331 for fixing the drive motor 340, the motor fixing sleeve 331 has side wings 332 extending outward, the fixed limit portion 333 is fixedly connected to the side wings 332, and extends from the side wings 332 toward the first transmission member 320.

[0126] By arranging the fixed limiting portion 333 on the motor fixing sleeve 331 used to fix the drive motor 340, the fixed limiting portion 333 and the side wing 332 can be integrally formed, and there is no need to integrally form the fixed limiting portion 333 on the middle frame 200. Even if the fixed limiting portion 333 is damaged, the motor fixing sleeve 331 can be removed from the middle frame 200 and replaced with the motor fixing sleeve 331, which is a smaller component in terms of volume and cost, thereby reducing maintenance costs.

[0127] like Figure 24 and Figure 25 Specifically, the inner sleeve portion 3223 can have a flattened hole that fits over the flattened shaft 341 of the drive motor 340, with the two being secured by friction. More specifically, the inner surface of the flattened hole includes a pair of parallel flat surfaces and two arcuate segments, with each point of the two arcuate segments equidistant from the center of the flattened hole. The cross-sectional shape of the flattened shaft 341 matches the inner surface of the flattened hole.

[0128] Specifically, a through hole may be provided on the side wing 332 , and threaded fasteners may be passed through the through hole to be fixed to the middle frame 200 , thereby fixing the motor fixing sleeve 331 to the middle frame 200 and further fixing the drive motor 340 to the middle frame 200 .

[0129] In addition to the above-mentioned solution of disposing the fixed limiting portion 333 on the side wing 332 , the fixed limiting portion 333 may also be disposed on the middle frame 200 .

[0130] like Figure 21-23 As shown, preferably, the accommodating space 510 passes through the wind sweeping link 500 along the thickness direction of the wind sweeping link 500, and the transmission protrusion 321 has an axial limiting portion 3211, which is used to prevent the transmission protrusion 321 from moving relative to the wind sweeping link 500 along the thickness direction of the wind sweeping link 500.

[0131] By setting the axial limiting portion 3211, the transmission protrusion 321 and the wind sweeping link 500 can be relatively fixed in the thickness direction of the wind sweeping link 500, and the first transmission member 320 is used to fix the free end of the wind sweeping link 500 in the thickness direction of the wind sweeping link 500, thereby reducing the shaking of the end of the wind sweeping link 500 connected to the first transmission member 320 due to not being limited by the wind sweeping box 600.

[0132] Specifically, the axial limiting portion 3211 may be a disc-shaped portion having a diameter greater than that of the transmission post and located at an end of the transmission post away from the transmission member body.

[0133] In addition, the present application also provides an embodiment, and the air conditioner provided in this embodiment includes the above-mentioned air conditioning sweeping device.

[0134] By arranging the above-mentioned air-conditioning sweeping device in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned electric control box assembly, which will not be described in detail here.

[0135] Although the present invention is disclosed as above, the present invention is not limited thereto.
