The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or implicitly specifying the number or order of the technical features indicated.

[0038] In the description of the present invention, it should be understood that “A is arranged on B” or “A is arranged on B” express the connection relationship or positional relationship between A and B, but does not mean that A must be above B.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "setting", "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or a communication between the two components. "Bolt connection" and "screw connection" are interchangeable. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0040] Reference Figure 2 、 Figure 5 and Figure 7, according to the anti-condensation method for air-conditioning outlet of an embodiment of the present invention, the air-conditioning outlet is provided with an air outlet housing 200, and an air outlet panel 210 is provided on one side of the air outlet housing 200. The air outlet panel 210 is provided with an air outlet opening 211, and left and right sweeping blades 100 are installed in the air outlet housing 200. The air blown by the blowing device of the air conditioner first enters the air outlet housing 200 from the other side of the air outlet housing 200, and then changes the left and right wind directions through the left and right sweeping blades 100, and finally blows out from the air outlet opening 211 to reach the outside. The upper inner area of ​​the air outlet panel 210 is called the first area 212, and the part of the wind that enters the air outlet housing 200 from the other side of the air outlet housing 200 and is close to the first area 212 is called the first wind. The method includes the following steps: blowing control, changing the wind direction of the first wind so that the first wind blows to the first area 212.

[0041] At the air outlet of an air conditioner, although most of the wind is blown directly out of the air outlet opening 211 to the outside, a small amount of wind will occasionally blow into the upper inner area of ​​the air outlet panel 210 (i.e., the first area 212) due to the obstruction of component shapes (such as the connecting rod 300), wind turbulence caused by changes in wind direction (such as the adjustment of the wind sweeping angle by the left and right sweeping blades 100), and wind turbulence caused by changes in wind speed. When there is little or no wind blowing into the first area 212, the outside wind will enter the first area 212 through various gaps or even directly from the edge of the air outlet opening 211. Therefore, there will be a phenomenon of cold and hot air converging in the first area 212, resulting in condensation in the first area 212, forming condensed water. The existence of condensation inside the air outlet of an air conditioner and the formation of condensed water are common problems in existing air conditioning systems. It is generally discharged through a drain pipe (common in the indoor unit of a wall-mounted air conditioner). The presence of condensed water will pollute the environment, affect people's use (accumulation and overflow or direct dripping onto people), and even flow into other parts of the air conditioner, corroding other parts and reducing the service life of the air conditioner.

[0042] The air-conditioning outlet anti-condensation method of the present invention, through the blowing control step, enables the first wind to always blow into the first area 212, so that the outside wind cannot contact the first area 212, and therefore there will be no condensation in the first area 212; the more fundamental reason is that since the first wind can always blow into the first area 212, the temperature of the first area 212 is always the same as (or very close to) the temperature of the first wind, so when the first wind blows into the first area 212, there will be no temperature change (or very little temperature change), no liquefaction phenomenon will occur, and no condensation water will be generated, and the outside wind (hot air) will be driven away by the first wind that always blows into the first area 212, and cannot contact the first area 212, and therefore no condensation water will be generated.

[0043] It should be understood that the anti-condensation method for air-conditioning outlets of the present invention is particularly suitable for air-conditioning types in which the air inlet and air outlet of the air conditioner are not arranged at the same place (or the two openings are far apart), and is particularly suitable for air-conditioning types with high requirements for continuous air supply and cooling; specifically, such as duct air conditioners, in particular, duct air conditioners used for cooling the computer room where the server is located, and duct air-conditioning systems in large office buildings, the two openings of the air conditioner are not arranged at the same place, and the air outlets of the air conditioner are in the air supply and cooling state during the working hours.

[0044] Reference Figure 2 In some embodiments of the present invention, in the blowing control step, an air guide is installed in the air outlet housing 200, and the air guide is arranged at an angle. The end of the air guide close to the air outlet panel 210 is higher, and the end of the air guide away from the air outlet panel 210 is lower. The first wind blows onto the upper surface of the air guide, and the air guide changes the wind direction of the first wind so that the first wind blows onto the first area 212.

[0045] The air guide blade is an independent part. When the air conditioner is assembled, the air guide blade is installed in the air outlet housing 200 and is tilted. The end of the air guide blade close to the air outlet panel 210 is higher (this end will not be so high as to abut the inner wall of the air outlet housing 200), and the end of the air guide blade away from the air outlet panel 210 is lower (or the end of the air guide blade close to the blowing device is lower, and the end of the air guide part 120 away from the air outlet panel 210 is lower), thereby forming an air guide surface. The wind blown by the blowing device first hits the lower end of the air guide surface, then rises along the air guide surface, and finally goes out from the high end of the air guide surface, thereby changing the direction of the first wind and blowing upward to the first area 212. It should be understood that the air guide surface can be an inclined surface (i.e., a plane) or a curved surface, such as an arcuate surface.

[0046] Reference Figure 2 and Figure 6 In some embodiments of the present invention, in the blowing control step, the direction of the first wind is changed by changing the structure of the left and right sweeping blades 100 (or by providing a wind guide structure on the left and right sweeping blades 100), so that the first wind blows to the first area 212.

[0047] The additional structure for changing the direction of the first wind is provided on the left and right sweep blades 100, eliminating the need for additional production and installation, reducing production and assembly costs, and conserving space within the air outlet housing 200. This eliminates the need for additional space, facilitating a reduction in the volume of the air outlet housing 200. It should be understood that the structural changes to the left and right sweep blades 100 can take various forms, such as providing an air guide portion 120 as in this embodiment, or providing an air guide hole that is angled upward to facilitate air guidance. Furthermore, the structure provided on the left and right sweep blades 100 is typically located within the air outlet housing 200 and is an integral component of the air conditioner's sweep assembly. When the left and right sweep blades 100 sweep air left and right (or after adjusting the sweep angle of the left and right sweep blades 100), the wind direction of the wind guide structure is minimally affected, ensuring that the first wind consistently strikes the first area 212 regardless of the sweep angle.

[0048] Reference Figure 2 and Figure 6 In some embodiments of the present invention, in the blowing control step, an air guide portion 120 is provided at the upper end of the main body portion 110 of the left and right sweeping blades 100. The end of the air guide portion 120 close to the air outlet panel 210 is higher, and the end of the air guide portion 120 away from the air outlet panel 210 is lower. The first wind blows onto the upper surface of the air guide portion 120, and the air guide portion 120 changes the wind direction of the first wind so that the first wind blows onto the first area 212.

[0049] The air guide portion 120 has a simple structure and is easy to produce. Compared with air guide holes, it has a larger air guide surface and a better air guide effect. It should be understood that in this embodiment, the main body 110, hinge portion 130, air guide portion 120, and connecting bracket 111 of the left and right sweeping blades 100 are all integrally formed.

[0050] Reference Figure 1 and Figure 5 In some embodiments of the present invention, a step of pasting a thermal insulation layer is also included, in which the thermal insulation layer is pasted on the outside of the air outlet panel 210 (specifically, generally on the upper area of ​​the outside of the air outlet panel 210), and the thermal insulation layer is made of a material with poor thermal conductivity (or thermal insulation material).

[0051] Materials with poor thermal conductivity (insulating materials) can be sponges, glass fibers, aerogel felt, vacuum panels, etc. Referring to the above-mentioned content on condensation at the air-conditioning outlet, a thermal insulation layer is pasted on the outside of the air outlet panel 210. First, the thermal insulation layer can prevent the outside air from directly contacting the outside of the air outlet panel 210. At the same time, the thermal insulation layer is provided to basically isolate the first wind from having adverse effects on the outside of the air outlet panel 210. Specifically, since the thermal insulation layer has the function of heat preservation and heat insulation, its thermal conductivity is very poor, so the part that directly contacts the outside of the air outlet panel 210 (i.e., the inner part of the thermal insulation layer) can be directly contacted with the air outlet panel 210. Its temperature will drop to a certain extent, but because of its low thermal conductivity, the influence of the air outlet panel 210 on the temperature of the insulation layer will become smaller and smaller from the middle of the insulation layer to the outer part of the insulation layer. Therefore, the outermost part of the insulation layer, that is, the part where the insulation layer (replacing the outer side of the air outlet panel 210) contacts the outside air, has a temperature that is basically the same as the outside temperature. Therefore, condensation will basically not form on the insulation layer, and condensation water will not be generated. At the same time, the insulation layer is also less likely to condense condensation water than the air outlet panel 210. It should be understood that sponges are bonded to both the inner and outer sides of the air outlet panel 210 to insulate the air outlet panel 210. Although this can prevent condensation water from forming on the air outlet panel 210, it still does not solve the fundamental problem of the intersection of cold and hot air. Therefore, condensation water can still form on the sponge on the inner side of the air outlet panel 210, and this process requires additional gluing and assembly of the inner side of the air outlet panel 210, which reduces production efficiency and affects the appearance of the product.

[0052] Reference Figure 2 and Figure 6 The left and right sweeping blades 100 according to an embodiment of the present invention are applied to the above-mentioned air-conditioning outlet anti-condensation method, and include a main body 110 and an air guide portion 120 .

[0053] The main body 110 is used to change the direction of the wind blowing from the air outlet opening 211 of the air outlet panel 210 to the outside world. The main body 110 is the original structure of the left and right sweeping blades 100 and is generally a vertical sheet-like structure. The wind blown by the blowing device first enters the air outlet housing 200 from the other side, then is changed in direction by the left and right sweeping blades 100, and finally blown out of the air outlet opening 211 to the outside world. Therefore, the left and right sweeping blades 100 play the role of changing the left and right wind direction of the wind blowing from the air outlet opening 211 of the air outlet panel 210 to the outside world.

[0054] The air guide portion 120 is disposed at the upper end of the main body 110. The end of the air guide portion 120 closer to the air outlet panel 210 is higher, while the end of the air guide portion 120 farther from the air outlet panel 210 is lower. The first wind blows against the upper surface of the air guide portion 120. The air guide portion 120 is used to change the direction of the first wind so that the first wind blows into the first area 212. It should be understood that the air guide portion 120 can be disposed at the uppermost end of the main body 110, or it can be disposed at other locations near the uppermost end of the main body 110. In this embodiment, the air guide portion 120 is also a sheet-like structure. It should be understood that in some other embodiments, the air guide portion 120 can also be a block-shaped, curved sheet-shaped, or other shaped structure. The principle of providing the air guide portion 120 to prevent condensation has been explained above and will not be repeated here.

[0055] Reference Figure 2 and Figure 7 In some embodiments of the present invention, the upper surface of the air guide portion 120 is an inclined surface.

[0056] The upper surface of the air guide portion 120 is an inclined surface (i.e., a flat surface), which facilitates the redirected first wind to directly blow into the first area 212, preventing the generation of turbulent wind flows such as eddies, and the flat structure is convenient for production and processing. It should be understood that the above-mentioned inclined surface has an air guide angle α (with the rotation center axis of the left and right sweeping blades 100 as the base axis, and the surface perpendicular to the main body 110 and coinciding with the above-mentioned rotation center axis as the reference plane, and the angle between the reference plane and the above-mentioned inclined surface is the air guide angle). The air guide angle needs to be designed to a suitable angle according to the overall size of the air outlet housing 200 to ensure that the cold air can blow into the first area 212. It should be understood that the upper surface of the air guide portion 120 can also be a curved surface.

[0057] Reference Figure 2 and Figure 6 In some embodiments of the present invention, a hinge portion 130 is further included. The hinge portion 130 is disposed at the lower end of the main body 110 , and the hinge portion 130 is used to rotatably connect to the air outlet housing 200 .

[0058] A special hinge 130 is provided to facilitate rotational connection to the air outlet housing 200, thereby allowing the left and right sweep blades 100 to rotate and further adjust the left and right sweep angles of the left and right sweep blades 100. It should be understood that the hinge 130 is a columnar or perforated structure for easy rotation.

[0059] Reference Figure 2 and Figure 6 In some embodiments of the present invention, a connecting column 111 is provided on one side of the main body 110 , and the connecting column 111 is used to connect the connecting rod 300 .

[0060] The connecting column 111 is used to connect the connecting rod 300, so that when the connecting rod 300 is pulled, the left and right wind sweeping blades 100 are rotated relative to the air outlet shell 200 (that is, the hinge part 130 is rotated), thereby changing the left and right wind direction of the wind blowing from the air outlet opening 211 of the air outlet panel 210 to the outside (that is, changing the left and right wind sweeping angles).

[0061] It should be understood that the left and right sweep blades 100 are integrally formed from the main body 110, hinge 130, air guide 120, and connecting post 111, facilitating ease of production. The connections between these components are strong and resist disconnection. It should be understood that the sweep angle of the left and right sweep blades 100 can be changed by pulling the connecting rod 300, as in this embodiment. Alternatively, the angle can be changed by other means, such as by connecting the hinge 130 to a gear, meshing a rack with the gear, and pulling the rack to change the sweep angle.

[0062] Reference Figure 2 The air conditioner according to the embodiment of the present invention includes the left and right wind sweeping blades 100 mentioned above.

[0063] Specifically, in this embodiment, the air conditioner further includes an air outlet housing 200, and the lower ends of the air guide portions 120 of the left and right sweeping blades 100 are rotatably connected within the air outlet housing 200. It should be understood that the air conditioner may also include other components such as a refrigeration device and an air blowing device, all of which are commonly used in the air conditioning field (such as a condenser, capillary tube, evaporator, electromagnetic reversing valve, filter, refrigerant, etc.), and their composition, connection, and operating process are not further described here.

[0064] Reference Figure 1 、 Figure 2 and Figure 5 According to an embodiment of the present invention, the air conditioning air sweeping assembly includes: an air outlet housing 200, which is provided with a limiting structure 510; left and right air sweeping blades 100, which include a main body 110 and a hinge part 130, the hinge part 130 is provided at the lower end of the main body 110, and the hinge part 130 is used to rotatably connect the air outlet housing 200; a connecting rod 300, one side of the connecting rod 300 is connected to one side of the main body 110; an anti-loosening baffle 400, one side of the anti-loosening baffle 400 is connected to the other side of the connecting rod 300, and the other side of the anti-loosening baffle 400 is provided with a limiting serration 410, and the limiting serration 410 is used to abut against the limiting structure 510.

[0065] In this embodiment, the limiting structure 510 is a raised flat plate-like structure, specifically, a portion of the connecting plate 500. In other embodiments, it can also be a pointed or convex structure or other structures. For example, the limiting structure 510 can be a rubber layer with a certain elastic deformation capacity and high friction resistance, which improves the fixing effect. The main body 110, which is the original structure of the left and right air sweeping blades 100, provides the left and right air sweeping function (or adjusts the air sweeping angle). The hinge 130 is a hole structure or a columnar structure, which facilitates rotation after connection. It should be understood that there are multiple left and right air sweeping blades 100, and connecting multiple left and right air sweeping blades 100 (main body 110) through the connecting rod 300 can simultaneously control the air sweeping angle of multiple left and right air sweeping blades 100. At the same time, because it is difficult to directly reach into the air outlet cavity of the air outlet housing 200 for operation, the connecting rod 300 is used to indirectly control the air sweeping angle adjustment of the left and right air sweeping blades 100, so that the connecting rod 300 can extend from the air outlet cavity to a location that is more convenient for direct operation or connection. The anti-loosening baffle 400 can be a detachable accessory component additionally installed on the connecting rod 300, or it can be a part of the connecting rod 300, a structure integrally formed with the connecting rod 300 or processed from the connecting rod 300 later, or it can be a component fixed to the connecting rod 300 by welding, bonding, hot melt connection, etc.

[0066] The limiting saw teeth 410 abut against the limiting structure 510, i.e., the limiting saw teeth 410 and the limiting structure 510 have an interference fit, thereby securing the anti-loosening baffle 400 to the limiting structure 510 through friction and the recessed locking structure of the limiting saw teeth 410. This also secures the connecting rod 300, preventing displacement under vibration. This ensures that the sweeping angles of the left and right sweeping blades 100 are fixed and do not change arbitrarily. When the sweeping angles of the left and right sweeping blades 100 need to be adjusted, the frictional resistance and structural resistance can be overcome by manually pulling the connecting rod 300, thereby driving the entire left and right sweeping blades 100 to rotate, i.e., adjusting the sweeping angles of the left and right sweeping blades 100. After adjustment, the connecting rod 300 is released, and the limiting saw teeth 410 and the limiting structure 510 remain in contact with each other, automatically limiting the position.

[0067] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present invention, a mounting slot 310 is provided on the other side of the connecting rod 300 , and the anti-loosening baffle 400 is detachably connected to the mounting slot 310 .

[0068] The anti-loosening baffle 400 is detachably connected to the mounting slot 310, facilitating maintenance and replacement of the anti-loosening baffle 400. In particular, when producing an air conditioner with automatic air sweeping, the anti-loosening baffle 400 only needs to be removed from the connecting rod 300 to prevent the air conditioner from automatically sweeping. For air conditioners with manual air sweeping, installing the anti-loosening baffle 400 can conveniently fix the sweeping angles of the left and right sweeping blades 100, preventing them from automatically changing due to vibration or wind, thereby improving product reliability. Therefore, the detachable anti-loosening baffle 400 eliminates the need for an additional mold to produce the connecting rod 300 parts for the automatic air sweeping model, reducing production costs. The modular integrated design improves efficiency and reduces costs.

[0069] Reference Figure 3 and Figure 6 In some embodiments of the present invention, a connecting column 111 is provided on one side of the main body 110, and a connecting slot 320 is provided on one side of the connecting rod 300. The connecting column 111 is inserted into the connecting slot 320, so that the main body 110 and the connecting rod 300 are connected.

[0070] The connection between the connecting post 111 and the connecting slot 320 is a composite connection of a snap connection, a detachable connection, and a rotating connection. The snap connection facilitates assembly and disassembly of the two.
