[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 with left and right sweeping function has been developed, and the existing sweeping components usually use a motor to drive the sweeping blades, and then drive other driven blades through a connecting rod mechanism to achieve sweeping, but the overall layout of this structure is relatively complicated, and because the force point is concentrated at the root of the blade, the root of the active sweeping blade is easy to break, causing the left and right sweeping functions of the whole machine to be paralyzed, which will lead to after-sales quality problems.

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

[0005] The problem solved by the invention is that the existing wind sweeping components have unreasonable structures, complex assembly and high failure rate.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that the technical features of each embodiment of the present invention can be combined with each other.

[0043] The directional terms mentioned in the embodiments of the present invention are all based on the normal assembly and normal installation of the indoor unit of the ceiling machine, where "upper" refers to the upper direction or space of the normal assembly and normal installation of the indoor unit of the ceiling machine, "lower" refers to the lower direction or space of the normal assembly and normal installation of the indoor unit of the ceiling machine, and "horizontal" refers to the horizontal plane direction of the normal assembly and normal installation of the indoor unit of the ceiling machine, which is the same as the conventional understanding. In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] Example 1

[0046] like Figure 1-8 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 H1, where L1 = (1.0-1.1) * H1. 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 pre-assembled normally, with strong compatibility.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Example 2

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] The outlet areas of the air outlet 21 corresponding to the first groove 212, the second groove 213, and the first boss 211 are 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 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), L6:L4:L5=(7-9):(12-14):(10-12). This setting makes the widths 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 from the middle position to the two ends first increases and then decreases, 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 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 in the frame 26 .

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

[0067] Example 3

This arrangement can constrain the assembly position of the air sweeping component 22, 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.

[0070] As a preferred example of the present invention, 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.

[0071] Preferably, a notch 263 is provided on the frame 26, and the notch 263 connects the air hole 28 with the air outlet 21, and is used to accommodate the driving device 222.

A connecting rod 223 is provided below the assembly plate 221, and the connecting rod 223 is provided perpendicular 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 limitedly assembled into the matching groove 264. This arrangement enables the wind sweeping component 22 to be fixed on both sides of the air outlet 21, and the assembly strength is good.

[0072] As a preferred example of the present invention, a first assembly groove 2211 is provided on one side of the assembly plate 221, and the first assembly groove 2211 is inclined to accommodate the third blade 2243.
