Description

TECHNICAL FIELD

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

[0002] The ceiling machine, also known as a ceiling machine or a ceiling machine, only leaks an air outlet after installation and cannot be seen inside the machine, has an elegant appearance and good temperature regulation effect, and has gradually become the first choice for large-scale and villa. Due to the limitation of the size of the existing ceiling machine air outlet and the single air outlet guide mode, 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 space temperature distribution, poor thermal feeling, and poor user experience may occur.

[0003] Therefore, a sweeping frame capable of expanding the air supply area is developed. Considering the processing difficulty and the appearance, the air outlet structure related to the ceiling machine is usually rectangular. At this time, the wind speed at the end of the air outlet is small, which may cause uneven air outlet. In addition, if the air outlet structure is unreasonable, it may seriously affect the overall wind resistance and noise of the ceiling machine, resulting in poor user experience.

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

[0005] The problem solved by the present application is how to reduce the wind resistance and noise of the sweeping frame to make the air outlet of the entire ceiling machine smoother.

[0006] The present application provides a sweeping frame, comprising a frame body, a through-air hole is formed in the middle of the frame body, an air outlet is arranged on the frame body, the air outlet is located on the outer peripheral side of the through-air hole, the end part of the air outlet is recessed to form a first groove, and the side wall of the first groove expands outward along the length direction of the air outlet from bottom to top to form a first guide slope.

[0007] This arrangement can guide the air flow to the center of the air outlet, effectively avoiding the collision between the air flow and the periphery of the first groove to generate condensation; ensure that all air flows are discharged through the air outlet, avoid the air flow into the gap between the sweeping frame and the main body due to the change of wind pressure during the sweeping process, and further prevent the air flow from being disturbed, and the overall operation noise is small.

[0008] Preferably, a first boss is arranged on the side wall of the air outlet along the length direction, the first boss is located in the middle of the air outlet and is arranged away from the through-air hole, and a second groove is formed between the first boss and the first groove. This arrangement increases the flow rate at the middle position of the air outlet, thereby guiding the air flow at the second groove position, reducing the air outlet resistance, and further increasing the air supply distance.

[0009] Preferably, the first recess is two and symmetrical on the left and right sides of the first boss, and the side wall of the first recess on the side away from the air hole is inclined upward to the side of the second recess and forms a second guide slope. This arrangement can guide the airflow at the end of the air outlet, making the air outlet more smooth; at the same time, the width of the air outlet at the first recess is narrower, which appropriately increases the airflow velocity of the corresponding area of the air outlet, thereby facilitating the uniformization of the overall flow velocity distribution at the air outlet.

This arrangement can effectively prevent the air flow from being turbulent and improve the air supply effect. Preferably, the distance between the first guide slope and the upper end surface of the frame body is M1, wherein M1=(0.4-0.6)*H. This arrangement can make the air flow enter the air outlet as much as possible, and make the air flow converge to the middle area of the air outlet through the first guide slope and the second guide slope, thereby making the air outlet more smooth.

[0015] Preferably, the third blade is two and symmetrically arranged on the left and right sides of the first boss. This arrangement is simple in structure and can make the air flow at both ends of the air outlet converge at the middle part, thereby achieving good air guiding effect.

[0016] Preferably, the air sweeping assembly comprises a driving device, the blade and the driving device are respectively arranged on the two sides of the assembly plate, the output end of the driving device is connected with one end of a crank, and the other end of the crank is connected with the blade through a connecting rod. This arrangement is simple in structure, stable and reliable in transmission, and convenient for production and processing.

[0017] Preferably, a limiting groove is arranged on the side wall of the air outlet near the air passing hole, and the assembly plate is embedded in the limiting groove. This arrangement can constrain the assembly position of the air sweeping assembly in the air outlet, thereby improving the assembly precision; and the side wall surface near the air passing hole of the air outlet is flat, so that the air flow is not interfered.

[0018] Preferably, a connecting rod is arranged on the assembly plate, the connecting rod is located on the side of the assembly plate away from the driving device, a matching groove is arranged on the first boss, and the free end of the connecting rod is assembled into the matching groove. This arrangement is simple in structure, the air sweeping assembly is closely attached to the frame, and the air flow is prevented from entering the gap between the air sweeping assembly and the frame to generate noise.

This setting can make full use of the existing structure between the main body 1 and the decorative panel 3 to quickly realize the pre-assembly between the air sweeping frame 2 and 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.

[0046] Preferably, the pre-assembly component 23 is two, located on both sides of the frame body 26. This setting 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 inside of the frame body 26, or on the outside of the frame body 26. Preferably, the pre-assembly component 23 is located on the inside of the frame body 26. This setting can ensure that the pre-assembly component 23 is located close to the operator, facilitating force application.

[0047] The outer edge of the air sweeping frame 2 is provided with an assembly structure 25, the assembly structure 25 includes a first connecting piece 252, the first connecting piece 252 is provided with an elastic piece 251 and a bolt 253, the bolt 253 is clamped and assembled on the elastic piece 251, and is used for detachable connection with the main body 1.

[0048] As an example of the present application, the elastic piece 251 includes 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 setting installs the bolt 253 on the first connecting piece 252 through the elastic piece 251 and always keeps the bolt 253 in a vertical state, and the assembly between the bolt 253 and the main body 1 can be completed by directly rotating the bolt 253 during installation, and an operator can complete the assembly alone, facilitating high-altitude operation.

[0049] 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; when assembling, the bolt 253 is assembled into the first avoiding hole 2516, and the limiting buckle 2514 on both sides is deformed by the elastic member 251 to abut against the nut part of the bolt 253 to realize quick assembly.

[0050] Preferably, the first cantilever 2512 and the second cantilever 2513 are provided with buckles 2515 on the side away from the limiting buckle 2514, and the buckles 2515 are used for detachable connection with the first connecting piece 252. This structure is simple 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 facilitates force application and helps the quick disassembly and assembly of the elastic member 251. There is a height difference between the buckle 2515 and the mounting plate 2511, which can make the elastic member 251 be on the first connecting piece 252 and can be elastically deformed, without interfering with the assembly of the bolt 253.

[0051] As an example of the present application, the first connecting piece 252 includes a first plate 2521 connected to the side wall of the frame body 26, a second plate 2522 is arranged above the first plate 2521, first and second lugs 2523 and 2524 are arranged on both sides of the second plate 2522, and through holes 2525 are arranged on the first and second lugs 2523 and 2524 for detachable connection with the elastic member 251.

[0052] As a preferred example of the present application, the second plate 2522 is perpendicular to the first plate 2521, a second avoiding hole 2526 is arranged on the second plate 2522 corresponding to the position of the bolt 253, and the first and second lugs 2523 and 2524 are located on the lower side of the second plate 2522. This arrangement can ensure that the assembled elastic member 251 and bolt 253 are located above the second plate 2522, avoiding interference with the pre-assembly between the air sweeping frame 2 and the main body 1; at the same time, the elastic member 251 itself has a certain deformation space, which will not interfere with the assembly of the bolt 253.

[0053] Preferably, the second plate 2522 is on the same plane as the upper end surface of the frame body 26. This arrangement can make the second plate 2522 closely fit with the cooperating structure on the main body 1, ensuring stable and reliable assembly.

[0054] 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.

[0055] Example 2

[0056] 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.

[0057] The air outlet 21 has a first protrusion 211 on its side wall along its length. The first protrusion 211 is located in the middle of the air outlet 21 and away from the air passage 28. The air outlet 21 has a first groove 212 at each end. The first groove 212 is symmetrically arranged on the left and right sides of the first protrusion 211. A second groove 213 is formed between the first protrusion 211 and the first groove 212. The side wall of the first groove 212 gradually expands from bottom to top away from the first protrusion 211 to form a first guide slope 2121.

[0058] This setting can guide the airflow towards the center of the air outlet 21, thereby effectively preventing the airflow from colliding with the periphery of the first groove 212 and causing condensation; in addition, it can ensure that all the airflow is discharged through the air outlet 21, preventing some of the airflow from entering the gap between the sweeping frame 2 and the main body 1 due to changes in air pressure during the sweeping process, thereby preventing the airflow from becoming turbulent and resulting in low overall operating noise.

[0059] Preferably, the sidewall of the first groove 212, on the side away from the air passage 28, slopes upwards towards the second groove 213 to form a second guide slope 2122. This arrangement guides the airflow at the end of the air outlet 21, making the airflow smoother; at the same time, the narrower width of the air outlet 21 at the first groove 212 appropriately increases the airflow velocity in the corresponding area, thereby helping to achieve a uniform overall velocity distribution at the air outlet 21.

[0060] The air outlet 21 has 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 respectively. The length of the first area a1, the second area a2 and the third area a3 is L3, L1 and L2 respectively. The width of the first area a1, the second area a2 and the third area a3 is L6, L4 and L5 respectively. L3:L1:L2=(1-2):(4-6):(8:12), L6:L4:L5=(7-9):(12-14):(10-12). This arrangement makes the width of the adjacent first area a1, the third area a3 and the second area a2 gradually increase, that is, the width of the air outlet 21 increases first and then decreases from the middle position to the two ends, so that the air flow velocity of the air outlet 21 is relatively uniform, and at the same time, 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.

[0061] 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. L7:(L2+2*L1+2*L3)=(1.05-1.1):1, L7: H=5.5-7:1. This arrangement can effectively prevent the air flow from being disturbed and improve the air supply effect. The distance between the first guide slope 2121 and the upper end surface of the frame 26 is M1, and M1=(0.4-0.6)H. This arrangement can make the air flow enter the air outlet 21 as much as possible, and make the air flow gather in 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.

[0062] As shown in Figures 11-14 The air sweeping assembly 22 includes an assembly plate 221 provided with a blade 224. The blade 224 includes a third blade 2243 arranged obliquely. The third blade 2243 is fixedly installed in the first area a1. The oblique direction of the third blade 2243 is the same as the oblique direction of the adjacent first guide slope 2121.

[0063] The third blade 2243 is arranged to guide the air flow at the end of the air outlet 21 to the central position, so as to cooperate with the first guide slope 2121 to avoid the collision between the blade 224 and the surrounding of the length direction of the air outlet 21 after the air flow direction is changed by the rotation of the blade 224, thereby preventing condensation. At the same time, the third blade 2243 cooperates with the first guide slope 2121 to achieve a gradual change effect, gradually changes the flow direction of the air flow, and has small running resistance.

[0064] The blades further comprise a first blade 2241 rotatably arranged in the third area a3 and a second blade 2242 arranged on both sides of the first blade 2241 and rotatably arranged in the second area a2. The arrangement can be adapted to the specific structure of the air outlet 21

[0065] Preferably, the air outlet 21 is provided with a limiting groove 262 on the side wall near the air passing hole 28, and the embedded part of the assembly plate 221 is arranged in the limiting groove 262. This arrangement can constrain the assembly position of the air sweeping assembly 22 on the air outlet 21, 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 smooth, and does not interfere with the air flow.

[0066] The frame 26 is provided with a supporting rod 261 arranged on the upper part of the air outlet 21 and near the limiting groove 262. This arrangement can strengthen the air outlet 21 and prevent it from deforming under the action of the air flow.

[0067] As a preferred example of the present application, the air sweeping assembly 22 further comprises a driving device 222, the blades 224 and the driving device 222 are arranged on both sides of the assembly plate 221, the output end of the driving device 222 is connected with one end of a crank 226, and the other end of the crank 226 is connected with the blades 224 through a connecting rod 225. This arrangement has simple structure, stable and reliable transmission, and is convenient for production and processing.

[0068] Preferably, the frame 26 is provided with a notch 263 for accommodating the driving device 222. This arrangement makes full use of the space of the frame 26, has simple structure and is convenient for wiring. The lower part of the assembly plate 221 is provided with a connecting rod 223 arranged perpendicularly to the assembly plate 221, the first boss 211 is provided with a matching groove 264, and one end of the connecting rod 223 is limitingly assembled into the matching groove 264. This arrangement can fix the air sweeping assembly 22 on both sides of the air outlet 21, and has good assembly strength.

[0069] Although the present application is disclosed as above, the present application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and the protection scope of the present application should be subject to the scope defined by the claims.
