Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping frame and a ceiling unit. Background Art

[0002] Ceiling air conditioners, also known as patio air conditioners or ceiling-mounted or embedded air conditioners, only expose the air outlet after installation, and the internal unit cannot be seen. They have a beautiful appearance and good temperature control effect, and have gradually become the first choice for large apartments and villas. Due to the limitations of the outlet size and the single air outlet and air guide method, the existing ceiling air conditioners usually only have a clear sense of wind in the area directly facing the outlet, while other areas in the horizontal direction have little sense of wind. During use, uneven spatial temperature distribution and poor thermal effect are prone to occur, resulting in poor user experience.

[0003] For this purpose, a sweeping frame that can expand the air supply area was developed. Taking into account the difficulty of processing and the aesthetic appearance, the air outlet structure related to the ceiling machine is usually rectangular. However, the wind speed at the end of the air outlet decreases, which can easily lead to uneven air outlet. In addition, if the air outlet structure is unreasonable, it will seriously affect the overall wind resistance and noise of the ceiling machine, resulting in a poor user experience.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The problem solved by the invention is how to reduce the wind resistance and noise of the wind sweeping frame so that the air outlet of the whole ceiling machine is smoother.

[0006] The present invention provides an air sweeping frame, comprising a frame body, a wind hole formed in the middle of the frame body, an air outlet arranged on the frame body, the air outlet being located on the outer peripheral side of the wind hole, an end portion of the air outlet being recessed to form a first groove, and a side wall of the first groove expanding outwardly from bottom to top along the length direction of the air outlet to form a first guide slope.

[0007] This setting can guide the outlet air flow to the center position of the air outlet, thereby effectively avoiding the outlet air flow from colliding with the periphery of the first groove and generating condensation; ensuring that all the outlet air flow is discharged through the air outlet, avoiding part of the outlet air flow from entering the gap between the air sweeping frame and the main body due to changes in wind pressure during the air sweeping process, thereby preventing the inlet air flow from being turbulent, and the overall operating noise is low.

[0008] Preferably, a first boss is provided 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 away from the air hole, and a second groove is formed between the first boss and the first groove. This arrangement increases the flow velocity at the middle position of the air outlet, thereby guiding the air flow at the position of the second groove, reducing the air outlet resistance and further increasing the air supply distance.

[0009] Preferably, there are two first grooves symmetrically arranged on the left and right sides of the first boss, and the first groove is inclined from bottom to top toward the second groove on the side away from the air hole to form a second guiding slope. This arrangement can guide the airflow at the end of the air outlet to make the air outlet smoother; at the same time, the width of the air outlet at the first groove is narrower, so that the airflow velocity of the corresponding area is appropriately increased, which is conducive to achieving uniform distribution of the overall flow velocity at the air outlet.

[0010] Preferably, the outlet areas corresponding to the first groove, the second groove and the first boss of the air outlet are respectively the first area a1, the second area a2 and the third area a3, and the lengths of the first area a1, the second area a2 and the third area a3 are respectively L 3 , L 1 , L 2 The widths of the first area a1, the second area a2, and the third area a3 are L respectively. 6 , L 4 , L 5 , where L 3 :L 1 :L 2 =(1-2):(4-6):(8-12), L 6 :L 4 :L 5 =(7-9):(12-14):(10-12).

[0011] This setting gradually increases the widths of the adjacent first area a1, third area a3, and second area a2, that is, the width of the air outlet first increases and then decreases from the middle position to the two ends, so that the air flow velocity of the air outlet is more uniform as a whole, while ensuring that the wind speed in the middle area of ​​the air outlet is relatively faster, thereby increasing the air delivery distance of the outlet air flow.

[0012] Preferably, the maximum length of the upper end of the air outlet is L 7 , the height of the air outlet is H, where L 7 :(L 2 +2*L 1 +2*L 3 )=(1.05-1.1):1,L 7 :H=5.5-7:1. This setting can effectively prevent the turbulence of the air flow and achieve a better air supply effect. Preferably, the distance between the first guide slope and the upper end surface of the frame is M 1 , where M 1 =(0.4-0.6)*H. This arrangement can make the outlet air flow enter the air outlet as much as possible, and make the outlet air flow converge to the middle area of ​​the air outlet through the first guide slope and the second guide slope, so that the air outlet is smoother.

[0013] Preferably, a wind sweeping assembly is provided in the air outlet, and the wind sweeping assembly includes an assembly plate and blades. The blades include an inclined third blade, and the third blade is fixedly mounted on the assembly plate and located in the first area a1. The inclination direction of the third blade is the same as the inclination direction of the adjacent first guide slope.

[0014] This arrangement guides the center of the airflow direction at the end of the air outlet, thereby cooperating with the first guide slope to prevent the blade from rotating to change the airflow direction and colliding with the surrounding of the length direction of the air outlet to produce condensation. At the same time, the third blade cooperates with the first guide slope to achieve a gradual effect, gradually changing the flow direction of the airflow, and having low running resistance.

[0015] Preferably, there are two third blades symmetrically arranged on the left and right sides of the first boss. This arrangement has a simple structure and can make the airflow at both ends of the air outlet converge to the middle part, with a good air guiding effect.

[0016] Preferably, the wind sweeping assembly includes a driving device, the blades and the driving device are respectively located on both sides of the assembly plate, the output end of the driving device is connected to one end of the crank, and the other end of the crank is connected to the blade through a connecting rod. This arrangement has a simple structure, stable and reliable transmission, and is easy to produce and process.

[0017] Preferably, the air outlet is provided with a limit groove on the side wall near the air hole, and the assembly plate is partially embedded in the limit groove. This arrangement can constrain the assembly position of the air sweeping component at the air outlet, with high assembly accuracy; at the same time, the side wall surface of the air outlet near the air hole is flat, which will not interfere with the air flow.

[0018] Preferably, a connecting rod is provided on the assembly plate, the connecting rod is located on a side of the assembly plate away from the driving device, a matching groove is provided on the first boss, and the free end of the connecting rod is limitedly assembled into the matching groove. This arrangement has a simple structure, and the air sweeping assembly fits tightly with the frame body, avoiding the airflow from entering the gap between the two and generating noise.

[0019] Compared with the prior art, the air sweeping frame of the present invention has the following beneficial effects: 1) by improving and optimizing the air outlet structure, condensation can be avoided at the end of the air outlet, while further improving the air flow velocity in the middle area of ​​the air outlet, thereby increasing the air supply distance of the air outlet; 2) all the outlet air flow is discharged through the air outlet to prevent it from entering the gap between the air sweeping frame and the main body to cause turbulence in the inlet air flow, and the operating noise is small; 3) the structure is simple and easy to produce and process.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Example 1

[0041] like Figure 1-9 As shown, a wind sweeping frame 2 is arranged on a ceiling machine, and the ceiling machine includes a detachably connected main body 1 and a decorative panel 3, the wind sweeping frame 2 is located between the main body 1 and the decorative panel 3, one side of the wind sweeping frame 2 is detachably connected to the main body 1, and the other side of the wind sweeping frame 2 is detachably connected to the decorative panel 3.

[0042] The air 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 air sweeping frame 2 as an optional accessory, without the need to set up additional connection structures on the main body 1 and the decorative panel 3, with little modification to the existing ceiling machine, and convenient implementation; by setting up the air sweeping frame 2, the ceiling machine can be swung to discharge air to further expand the air outlet coverage, which is conducive to realizing rapid indoor temperature control and better user experience. The main body 1 includes a chassis, a frame, an evaporator, a wind resistance component, an electric control box, etc. The relevant structures and assembly relationships are all prior art and will not be repeated here.

[0043] Preferably, the wind sweeping frame 2 includes a "mouth-shaped" frame 26, and the frame 26 is provided with a pre-installed component 23 for pre-assembly with the main body 1 and / or the decorative panel 3. As an example of the present invention, the pre-installed component 23 includes a connecting plate 231, and the connecting plate 231 is provided with a hook 232 on a side close to the main body 1, and the protrusion of the hook 232 is provided on the frame 26 for pre-fixation with the main body 1. This setting can pre-assemble the wind sweeping frame 2 on the main body 1 and constrain the relative position of the two, which is conducive to assembly with the main body 1 through screws.

[0044] As a preferred example of the present invention, the frame 26 is provided with an air outlet 21, and a wind sweeping assembly 22 is provided at the position of the air outlet 21 for guiding the outlet air flow; an electric control structure 24 is provided inside the frame 26, and the electric control structure 24 is electrically connected to the wind sweeping assembly 22. Preferably, the wind sweeping frame 2 also includes a reinforcement 27, and the reinforcement 27 is located inside the frame 26, and the electric control structure 24 is fixedly assembled on the reinforcement 27. This arrangement can strengthen the frame 26, and is also conducive to setting the pre-installed assembly 23, etc., to ensure stable and reliable connection.

[0045] As an example of the present invention, the connecting plate 231 is bent at a side away from the hook 232 to form a slot, the distance between the slot and the hook 232 is L1, and the height of the frame 26 is H 1 , where L 1=(1.0-1.1)*H 1 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 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 pre-assembled normally, and the compatibility is strong.

[0046] Preferably, there are two pre-installed components 23, which are respectively located on both sides of the frame 26. This arrangement can ensure that the pre-installed components 23 are balanced in force, and can take into account both the convenience and reliability of operation. The pre-installed components 23 can be located on the inner side of the frame 26, or on the outer side of the frame 26. Preferably, the pre-installed components 23 are located on the inner side of the frame 26. This arrangement can ensure that the pre-installed components 23 are located close to the operator, which is convenient for applying force.

[0047] The outer edge of the wind sweeping frame 2 is provided with an assembly structure 25, and the assembly structure 25 includes a first connecting member 252, and the first connecting member 252 is provided with an elastic member 251 and a bolt 253, and the bolt 253 is snap-fitted and assembled on the elastic member 251, and is used for detachable connection with the main body 1. This arrangement can limit the position of the bolt 253, and after the wind sweeping frame 2 and the main body 1 are pre-assembled, the assembly between the wind sweeping frame 2 and the main body 1 can be completed by rotating the bolt 253 upward, and the installation efficiency is high.

[0048] As an example of the present invention, the elastic member 251 includes a mounting plate 2511, and a first cantilever 2512 and a second cantilever 2513 are respectively arranged on both sides of the mounting plate 2511. The first cantilever 2512 and the second cantilever 2513 are respectively detachably connected to the first connecting member 252. The mounting plate 2511 is provided with a first avoidance hole 2516 and a limit buckle 2514. One end of the bolt 253 is arranged through the first avoidance hole 2516, and the other end of the bolt 253 is limitedly assembled with the limit buckle 2514. This arrangement installs the bolt 253 on the first connecting member 252 through the elastic member 251 and keeps the bolt 253 in a vertical state at all times. During installation, the bolt 253 can be directly rotated to complete the assembly with the main body 1. The operator can complete the assembly alone, which is convenient for high-altitude operations.

[0049] Preferably, there are two limit buckles 2514, which are symmetrically arranged on the left and right sides of the first avoidance hole 2516. This arrangement can ensure that both sides of the bolt 253 are evenly stressed and always in a vertical state; during assembly, the bolt 253 is assembled into the first avoidance hole 2516, and force is applied to deform the elastic member 251 so that the limit buckles 2514 on both sides abut against the nut portion of the bolt 253 to achieve rapid assembly.

[0050] Preferably, the first cantilever 2512 and the second cantilever 2513 are provided with a buckle 2515 on a side away from the limit buckle 2514, and the buckle 2515 is used to be detachably connected to the first connecting member 252. This arrangement has a simple structure and is convenient for production and processing. Preferably, a boss 2517 is provided on the first cantilever 2512 and / or the second cantilever 2513, and a convex rib is provided on the outer peripheral side of the boss 2517. This arrangement facilitates the application of force and helps to quickly disassemble and assemble the elastic member 251. There is a height difference between the buckle 2515 and the mounting plate 2511. This arrangement enables the elastic member 251 to be on the first connecting member 252 and to be elastically deformed, without interfering with the assembly of the bolt 253.

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

[0052] As a preferred example of the present invention, the second plate 2522 is arranged perpendicular to the first plate 2521, a second avoidance hole 2526 is arranged on the second plate 2522 at a position corresponding to the bolt 253, and the first lug 2523 and the second lug 2524 are located at the lower side of the second plate 2522. This arrangement can ensure that the elastic member 251 and the bolt 253 after assembly are both located above the second plate 2522, avoiding interference with the pre-assembly between the wind 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 and the upper end surface of the frame 26 are in the same plane. This arrangement enables the second plate 2522 to fit closely with the matching structure on the main body 1, ensuring stable and reliable assembly. The hook 232 is clamped on the main body 1, and the bolt 253 corresponds to the position of the assembly hole on the main body 1. By applying force to the bolt 253, it overcomes the elastic force of the elastic member 251 and moves upward, passes through the through hole 2525, and is screwed and assembled with the main body 1.

[0054] Preferably, the assembly structure 25 further includes a second connecting member 254, the second connecting member 254 is located directly below the first connecting member 252, the second connecting member 254 is provided with an assembly hole, the assembly hole is arranged opposite to the second avoidance hole 2526, and is used to be connected to the decorative panel 3. This arrangement can utilize the existing main body 1 and decorative panel 3 to realize the assembly of the wind sweeping frame 2, and has a simple structure and is easy to produce and process.

[0055] Example 2

[0056] like Figure 9-11 As shown, the wind sweeping frame 2 includes a U-shaped frame body 26, a wind hole 28 is formed in the middle of the frame body 26, an air outlet 21 is arranged on the outer peripheral side of the air hole 28, and the air outlet 21 is overall in the shape of a long strip and a wind sweeping component 22 is arranged inside to adjust the lateral angle of the outlet air flow.

[0057] A first boss 211 is provided on the side wall of the air outlet 21 along the length direction, the first boss 211 is located in the middle of the air outlet 21 and is arranged away from the air hole 28, first grooves 212 are respectively provided at both ends of the air outlet 21, the first grooves 212 are symmetrically arranged on the left and right sides of the first boss 211, a second groove 213 is formed between the first boss 211 and the first groove 212, and the side wall of the first groove 212 gradually expands from bottom to top toward the side away from the first boss 211 to form a first guide slope 2121.

[0058] This setting can guide the outlet air flow to the center position of the air outlet 21, thereby effectively avoiding the outlet air flow from colliding with the periphery of the first groove 212 and generating condensation; in addition, it can make all the outlet air flow be discharged through the air outlet 21, preventing part of the outlet air flow from entering the gap between the air sweeping frame 2 and the main body 1 due to changes in wind pressure during the air sweeping process, thereby preventing the inlet air flow from being turbulent, and the overall operating noise is low.

[0059] Preferably, the side wall of the first groove 212 away from the air hole 28 is inclined from bottom to top toward the second groove 213 to form a second guiding slope 2122. This arrangement can guide the airflow at the end of the air outlet 21 to make the air outlet smoother; at the same time, the width of the air outlet 21 at the first groove 212 is narrower, so that the airflow velocity of the corresponding area is appropriately increased, which is conducive to achieving uniform distribution of the overall flow velocity at the air outlet 21.

[0060] The air outlet 21 has the first groove 212, the second groove 213, and the first boss 211, and the air outlet areas corresponding to the first area a1, the second area a2, and the third area a3, respectively. The lengths of the first area a1, the second area a2, and the third area a3 are L, respectively. 3 , L 1 , L 2 The widths of the first area a1, the second area a2, and the third area a3 are L respectively. 6 , L 4 , L 5 , where L 3 :L 1 :L 2=(1-2):(4-6):(8:12),L 6 :L 4 :L 5 =(7-9):(12-14):(10-12). This arrangement makes the widths of the adjacent first area a1, third area a3, and 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 as a whole, and at the same time ensures that the wind speed in the middle area of ​​the air outlet 21 is relatively faster, thereby increasing the air delivery distance of the air outlet airflow.

[0061] The maximum length of the air outlet 21 on the side close to the main body 1 is L 7 , the height of the air outlet 21 is H, where L 7 :(L 2 +2*L 1 +2*L 3 )=(1.05-1.1):1,L 7 :H=5.5-7:1. This setting can effectively prevent the turbulence of the air flow and achieve a better air supply effect. The distance between the first guide slope 2121 and the upper end surface of the frame 26 is M 1 , where M 1 =(0.4-0.6)H. This arrangement can make the outlet air flow enter the air outlet 21 as much as possible, and make the outlet 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 flow is smoother.

The blade 224 includes an inclined third blade 2243. The third blade 2243 is fixedly installed in the first area a1, and the inclination direction of the third blade 2243 is the same as the inclination direction of the adjacent first guide slope 2121.

[0063] The third blade 2243 is provided to guide the center of the airflow direction at the end of the air outlet 21, thereby cooperating with the first guide slope 2121 to prevent the blade 224 from rotating to change the airflow direction and colliding with the periphery in the length direction of the air outlet 21 to generate condensation. At the same time, the third blade 2243 cooperates with the first guide slope 2121 to achieve a gradual effect, gradually changing the airflow direction, and having a small running resistance.

[0064] The blades further include a first blade 2241 and a second blade 2242. The first blade 2241 is rotatably disposed in the third area a3, and the second blade 2242 is located on both sides of the first blade 2241 and is rotatably disposed in the second area a2. This 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 hole 28, and the assembly plate 221 is partially embedded in the limiting groove 262. This arrangement can constrain the assembly position of the air sweeping component 22 on the air outlet 21, and the assembly accuracy is high; at the same time, the side wall surface of the air outlet 21 near the air hole 28 is flat, and will not interfere with the air flow.

[0066] The frame 26 is provided with a support rod 261, and the support rod 261 is located at the upper part of the air outlet 21 and is arranged close to the limiting groove 262. This arrangement can strengthen the air outlet 21 and prevent deformation under the action of the outlet airflow.

[0067] As a preferred example of the present invention, the wind sweeping assembly 22 further includes a driving device 222, the blades 224 and the driving device 222 are respectively located on both sides of the assembly plate 221, the output end of the driving device 222 is connected to one end of a crank 226, and the other end of the crank 226 is connected to the blade 224 through a connecting rod 225. The arrangement has a simple structure, stable and reliable transmission, and is easy to produce and process.

[0068] Preferably, a notch 263 is provided on the frame 26, and the notch 263 is used to accommodate the driving device 222. This arrangement makes full use of the space of the frame 26, has a simple structure and is convenient for wiring.

The first boss 211 is provided with a matching groove 264, and one end of the connecting rod 223 is limitedly assembled in the matching groove 264. This arrangement enables the air sweeping assembly 22 to be fixed on both sides of the air outlet 21, and the assembly strength is good.

[0069] Although the present invention is disclosed as above, the present invention is not limited thereto.
