[0001] The present application relates to the air conditioning technical field, and in particular, relates to a wind sweeping assembly, a wind sweeping frame and a ceiling air conditioner. BACKGROUND

[0002] The ceiling air conditioner, also known as a ceiling air conditioner or a ceiling air conditioner, only leaks an air outlet after installation and cannot see the inner machine, has an elegant appearance and good temperature adjustment effect, and has gradually become the first choice for large-scale and villa. Due to the limitation of the size of the air outlet and the single air outlet guide mode of the existing ceiling air conditioner, only the area directly opposite the air outlet has obvious wind feeling, and other areas in the horizontal direction have little wind feeling. During use, uneven temperature distribution in space, poor thermal feeling, and poor user experience.

[0003] Therefore, a wind sweeping frame with left and right wind sweeping functions is developed, and the existing wind sweeping assembly usually drives the wind sweeping blades by a motor, and drives other driven blades by a connecting rod mechanism to realize wind sweeping. However, the overall layout of this structure is relatively complex, and the stress point is concentrated at the root of the blade, which makes the root of the driven wind sweeping blade prone to break, causing the left and right wind sweeping functions of the whole machine to be paralyzed, which may cause after-sales quality problems.

[0004] Therefore, the present application is proposed. SUMMARY

[0005] The problem solved by the present application is that the structure of the existing wind sweeping assembly is unreasonable, the assembly is complex, and the failure rate is high.

[0010] The third blade is arranged to guide the central position of the air flow at the end of the air outlet, thereby cooperating with the first guide slope to avoid collision between the air flow and the surrounding of the length direction of the air outlet after the rotation of the blade changes the flow direction, thereby preventing condensation.

[0011] Preferably, the driving device comprises a detachable box body and a box cover, a transmission structure is arranged in the box body, a motor is arranged on the side of the box cover away from the box body, and the motor is drivingly connected with the transmission structure.

[0045] Embodiment 1

[0046] As shown in Figures 1-8 A sweeping frame 2 is provided on a ceiling machine, the ceiling machine comprising a main body 1 and a decorative panel 3 which are detachably connected, the sweeping frame 2 being located between the main body 1 and the decorative panel 3, one side of the sweeping frame 2 being detachably connected with the main body 1, and the other side of the sweeping frame 2 being detachably connected with the decorative panel 3.

[0047] The sweeping frame 2 of the present application can be installed by using the assembly components between the main body 1 and the decorative panel 3 of the existing ceiling machine, so as to realize the quick installation of the sweeping frame 2 as an optional accessory, without the need to set additional connecting structures on the main body 1 and the decorative panel 3, which is convenient to implement and has little modification to the existing ceiling machine. By setting the sweeping frame 2, the swinging outflow of the ceiling machine can be realized to further expand the outflow coverage, which is beneficial to realize the quick temperature adjustment of the indoor space and provides better user experience. The main body 1 comprises a bottom plate, a surrounding frame, an evaporator, a wind resistance assembly, an electric control box and the like, and the related structures and assembly relationship are all prior art, which will not be described here.

[0048] Preferably, the air-sweeping frame 2 comprises a frame body 26 in the shape of a "mouth-shaped character", which is provided with a pre-assembly component 23 for pre-assembly with the main body 1 and / or the decorative panel 3. As an example of the present application, the pre-assembly component 23 comprises a connecting plate 231, which is provided with a clamping hook 232 on the side close to the main body 1, and the protrusion of the clamping hook 232 is provided on the frame body 26 for pre-fixing with the main body 1. This arrangement can pre-assemble the air-sweeping frame 2 on the main body 1 and constrain the relative positions of the two, which is conducive to assembly with the main body 1 through screws.

[0049] As a preferred example of the present application, the frame body 26 is provided with an air outlet 21, and the air-sweeping component 22 is arranged at the air outlet 21 for air deflection of the air flow; and the frame body 26 is provided with an electric control structure 24 on the inner side, which is electrically connected with the air-sweeping component 22. Preferably, the air-sweeping frame 2 further comprises a reinforcing member 27, which is located on the inner side of the frame body 26, and the electric control structure 24 is fixedly assembled on the reinforcing member 27. This arrangement can reinforce the frame body 26, and is conducive to the arrangement of the pre-assembly component 23 and the like, ensuring stable and reliable connection.

[0050] As an example of the present application, the connecting plate 231 is bent to form a clamping groove on the side away from the clamping hook 232, and the distance between the clamping groove and the clamping hook 232 is L1, and the height of the frame body 26 is H1, wherein L1 = (1.0-1.1) * H1. This arrangement can make full use of the existing structure between the main body 1 and the decorative panel 3 to quickly realize the pre-assembly of the air-sweeping frame 2 with the main body 1 and the decorative panel 3, greatly improving the assembly efficiency; if there is no air-sweeping frame 2, the main body 1 and the decorative panel 3 can be normally pre-assembled, and the compatibility is strong.

[0051] Preferably, the pre-assembly component 23 is two, which are respectively located on both sides of the frame body 26. This arrangement can ensure that the pre-assembly component 23 is balanced in force, and can take into account the convenience and reliability of operation. The pre-assembly component 23 can be located on the inner side of the frame body 26, or on the outer side of the frame body 26. Preferably, the pre-assembly component 23 is located on the inner side of the frame body 26. This arrangement can ensure that the pre-assembly component 23 is located close to the operator, which is convenient for force application.

[0052] The outer edge of the air-sweeping frame 2 is provided with an assembly structure 25, which comprises a first connecting piece 252, an elastic piece 251, and a bolt 253 clamped and assembled on the elastic piece 251 and used for detachable connection with the main body 1. This arrangement can limit the position of the bolt 253, and after the air-sweeping frame 2 and the main body 1 are pre-assembled, the assembly between the air-sweeping frame 2 and the main body 1 can be completed by rotating the bolt 253 upward, which is high in installation efficiency.

[0053] As an example of the present application, the elastic piece 251 comprises a mounting plate 2511, the two sides of the mounting plate 2511 are respectively provided with a first cantilever 2512 and a second cantilever 2513, the first cantilever 2512 and the second cantilever 2513 are respectively detachably connected with the first connecting piece 252, the mounting plate 2511 is provided with a first avoiding hole 2516 and a limiting buckle 2514, one end of the bolt 253 passes through the first avoiding hole 2516, and the other end of the bolt 253 is limitingly assembled with the limiting buckle 2514. This arrangement installs the bolt 253 on the first connecting piece 252 through the elastic piece 251 and keeps the bolt 253 in a vertical state at all times, and the assembly between the bolt 253 and the main body 1 can be completed by directly rotating the bolt 253 during installation, which can be completed by one operator and is convenient for high-altitude operation.

[0054] Preferably, the limiting buckle 2514 is two and symmetrically arranged on the left and right sides of the first avoiding hole 2516. This arrangement can ensure that the two sides of the bolt 253 are uniformly stressed and always in a vertical state; during assembly, the bolt 253 is assembled into the first avoiding hole 2516, and the elastic piece 251 is deformed by applying force to make the limiting buckles 2514 on the two sides abut against the nut part of the bolt 253 to realize rapid assembly.

[0055] Preferably, the first cantilever 2512 and the second cantilever 2513 are provided with buckles 2515 on the sides away from the limiting buckles 2514, and the buckles 2515 are used for detachable connection with the first connecting piece 252. This arrangement is simple in structure and convenient for production and processing. Preferably, the first cantilever 2512 and / or the second cantilever 2513 are provided with a protruding column 2517, and the outer circumferential side of the protruding column 2517 is provided with a protruding rib. This arrangement is convenient for applying force and helps rapid disassembly and assembly of the elastic piece 251. There is a height difference between the buckle 2515 and the mounting plate 2511, which can make the elastic piece 251 be on the first connecting piece 252 and be elastically deformed, and does not interfere with the assembly of the bolt 253.

[0056] As an example of the present invention, the first connector 252 includes a first plate 2521 connected to the side wall of the frame 26, a second plate 2522 is disposed above the first plate 2521, a first lug 2523 and a second lug 2524 are respectively disposed on both sides of the second plate 2522, and through holes 2525 are provided on the first lug 2523 and the second lug 2524 for detachable connection with the elastic member 251.

[0057] As a preferred embodiment of the present invention, the second plate 2522 is disposed perpendicular to the first plate 2521, and a second clearance hole 2526 is provided on the second plate 2522 at a position corresponding to the bolt 253. The first lug 2523 and the second lug 2524 are located on the lower side of the second plate 2522. This arrangement ensures that the assembled elastic element 251 and the bolt 253 are both located above the second plate 2522, avoiding interference with the pre-assembly between the sweeping frame 2 and the main body 1; at the same time, it allows the elastic element 251 to have a certain deformation space, so as not to interfere with the assembly of the bolt 253.

[0058] Preferably, the second plate 2522 and the upper surface of the frame 26 are on the same plane. This arrangement allows the second plate 2522 to fit tightly with the mating structure on the main body 1, ensuring stable and reliable assembly. The hook 232 is engaged with the main body 1, at which point the bolt 253 corresponds to the mounting hole on the main body 1. By applying force to the bolt 253, it overcomes the elastic force of the elastic element 251 and moves upward, passing through the through hole 2525 and then being screwed into the main body 1.

[0059] Preferably, the assembly structure 25 further includes a second connector 254, which is located directly below the first connector 252. The second connector 254 has an assembly hole that is directly opposite to the second clearance hole 2526 for connection with the decorative panel 3. This arrangement allows for the assembly of the air-sweeping frame 2 using the existing main body 1 and decorative panel 3, resulting in a simple structure that is easy to manufacture.

[0060] Example 2

[0061] like Figures 9-11 As shown, the air-sweeping frame 2 includes a U-shaped frame 26, with an air passage hole 28 formed in the middle of the frame 26. An air outlet 21 is provided on the outer periphery of the air passage hole 28. The air outlet 21 is elongated and has an air-sweeping component 22 inside, which is used to adjust the lateral angle of the airflow.

[0062] The first boss 211 is arranged on the side wall of the air outlet 21 along the length direction, and is located in the middle of the air outlet 21 and away from the air passing hole 28. The air outlet 21 is respectively provided with a first groove 212 at both ends, and the first grooves 212 are symmetrically arranged on the left and right sides of the first boss 211. The first boss 211 and the first grooves 212 form a second groove 213. The side wall of the first groove 212 gradually expands from bottom to top to the side away from the first boss 211 to form a first guide slope 2121.

[0063] The arrangement can guide the air flow to the central position of the air outlet 21, thereby effectively avoiding the collision between the air flow and the periphery of the first groove 212 to generate condensation. In addition, the air flow can be discharged through the air outlet 21, preventing the air flow from entering the gap between the air sweeping frame 2 and the main body 1 due to the change of air pressure during the air sweeping process, thereby preventing the air flow from being disturbed and reducing the overall operation noise.

[0064] Preferably, the side wall of the first groove 212 on the side away from the air passing hole 28 is inclined from bottom to top to the side of the second groove 213 and forms a second guide slope 2122. The arrangement can guide the air flow at the end of the air outlet 21, making the air outlet 21 more smooth. At the same time, the width of the air outlet 21 at the first groove 212 is relatively narrow, so that the flow rate of the air flow in the corresponding area is appropriately increased, thereby facilitating the uniformization of the overall flow rate distribution at the air outlet 21.

[0065] The air outlet 21 is respectively provided with a first area a1, a second area a2 and a third area a3 corresponding to the first groove 212, the second groove 213 and the first boss 211. The lengths of the first area a1, the second area a2 and the third area a3 are L3, L1 and L2 respectively. The widths of the first area a1, the second area a2 and the third area a3 are L6, L4 and L5 respectively, wherein L3:L1:L2=(1-2):(4-6):(8:12), and L6:L4:L5=(7-9):(12-14):(10-12). The arrangement gradually increases the widths of the first area a1, the third area a3 and the second area a2, that is, the width of the air outlet 21 first increases and then decreases from the middle position to both ends, thereby making the air flow rate of the air outlet 21 more uniform, and ensuring that the air speed in the middle area of the air outlet 21 is relatively faster, thereby improving the air supply distance of the air flow. It should be noted that the size of the air outlet 21 refers to the actual size of the air outlet 21 formed after the air sweeping assembly 22 is installed to the frame body 26.

[0066] The maximum length of the air outlet 21 near the main body 1 is L7, and the height of the air outlet 21 is H, wherein L7:(L2+2*L1+2*L3)=(1.05-1.1):1, L7:H=5.5-7:1. This setting can effectively prevent the air flow from being disordered, and the air supply effect is better. The distance between the first guide slope 2121 and the upper end surface of the frame body 26 is M1, wherein M1=(0.4-0.6)H. This setting can make the air flow into the air outlet 21 as much as possible, and make the air flow converge to the middle area of the air outlet 21 through the first guide slope 2121 and the second guide slope 2122, so that the air outlet is smoother.

This setting can constrain the assembly position of the air sweeping assembly 22, and has high assembly precision. At the same time, the side wall surface of the air outlet 21 near the air passing hole 28 is flat, and does not interfere with the air flow.

[0070] As a preferred example of the present application, the frame body 26 is provided with a support rod 261, which is arranged at the upper part of the air outlet 21 and near the limiting groove 262. This setting can strengthen the air outlet 21 and prevent it from deforming under the action of the air flow.
