Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air sweeping blade and an air conditioner. Background Art

[0002] Among household air conditioners, wall-mounted air conditioners are more commonly used because they do not occupy the effective area of ​​the room. The wall-mounted unit is fixedly installed on the indoor wall and blows hot or cold air into the room through the air outlet. In order to achieve the left and right air sweeping of the wall-mounted air conditioner, it is generally necessary to set a sweeping blade at the air outlet; and the sweeping blade is generally a sheet structure. During operation, the temperature difference on both sides of the sweeping blade is inconsistent, which is easy to condense. When a lot of condensation accumulates, it is easy to drip indoors, seriously affecting the user experience. Summary of the invention

[0003] The problem solved by the invention is to improve the water dripping phenomenon of the wind sweeping blades.

[0004] To solve the above problems, the present invention provides a wind sweeping blade, which includes a blade frame and a blade body arranged on the blade frame, wherein the blade frame is used to support the blade body, and the blade body is at least partially a mesh structure so that air can flow through the mesh structure.

[0005] Since the wind sweeping blade is provided with a mesh structure, air can flow through the mesh structure, reducing the temperature difference on both sides of the wind blade, which makes it difficult for condensation to form. In addition, even if a small amount of condensation is formed, the condensation will hang in the mesh holes of the mesh structure; it is difficult to gather and form water droplets. Therefore, the wind sweeping blade can effectively improve the dripping phenomenon of the wind sweeping blade.

[0006] Furthermore, the mesh structure accounts for an area range of 30%-80%. If the mesh structure accounts for too large an area, it will directly reduce the overall strength of the wind sweeping blades and make the wind sweeping blades easily deformed; if the mesh structure accounts for too small an area, the effect of preventing condensation is not obvious and it is difficult to fundamentally solve the problem of anti-drip.

[0007] Furthermore, the blade skeleton includes an outer frame, a main support rod and at least one auxiliary support rod; one end of the auxiliary support rod is connected to the main support rod, and the other end extends toward the direction close to the outer frame; the main support rod is connected to the outer frame.

[0008] The wind sweeping blade adopts a bionic structure, and the shape of its blade skeleton and mesh structure is similar to the structure of leaves. This structure not only makes the mesh structure less likely to deform, but also effectively increases the area occupied by the mesh structure; in addition, the wind sweeping blade is light in weight and more flexible in swinging.

[0009] Furthermore, along the extension direction of the secondary support rod, the cross-sectional dimension of the secondary support rod gradually decreases. Along the extension direction of the secondary support rod refers to from one end of the secondary support rod connected to the main support rod to the other end of the secondary support rod.

[0010] Since the main support rod mainly bears the weight of the entire wind sweeping blade and drives the entire wind sweeping blade to swing, the main support rod is relatively thick. The outer frame is mainly used to fix the edge of the mesh structure, and its thickness is slightly greater than the thickness of the mesh structure. The auxiliary support rod is mainly used to fix the mesh surface of the mesh structure to prevent it from deforming. Therefore, the end of the auxiliary support rod close to the main support rod is relatively thick, and the end close to the outer frame is relatively thin, so that it is easy to connect with the main support rod and the outer frame.

[0011] Furthermore, along the extension direction of the main support rod, the cross-sectional size of the main support rod gradually decreases.

[0012] The above structure enables the main support rod to not only effectively support the entire blade frame, but also makes the blade frame relatively light and convenient for flexible swinging.

[0013] Furthermore, the mesh number of the mesh structure is 4-325 meshes.

[0014] The mesh size corresponding to the above mesh number is 4.75mm-0.0450mm. When the mesh size is too large, the air leakage is serious, which is not conducive to the effective air sweeping of the wind sweeping blades; when the mesh size is too small, the anti-condensation effect is not obvious.

[0015] Furthermore, the mesh size of the mesh structure is 100-200 meshes, and the mesh size corresponds to 0.15mm-0.075mm; the mesh size is a preferred solution.

[0016] Furthermore, the blade skeleton is integrally injection molded.

[0017] The wind sweeping blade adopts an integrally formed structure, which is easy to process and has high overall strength.

[0018] Furthermore, the first connecting portion is a cylindrical structure, and the second connecting portion is a pin structure.

[0019] The present application also provides an air conditioner, the air conditioner includes a wall-mounted unit, and the air sweeping blade is provided on at least one side of the air outlet of the wall-mounted unit. The one side of the air outlet refers to the leftmost or rightmost side of the air outlet. The air outlet may be provided with a sweeping blade with a mesh structure only on the leftmost or rightmost side; or the sweeping blades at the air outlet may all be the sweeping blades with the mesh structure.

[0020] Furthermore, the wall-mounted machine includes a plurality of the wind sweeping blades, which are arranged at intervals at the air outlet of the wall-mounted machine; the pores of the mesh structure near both sides of the air outlet are larger than the pores of the mesh structure near the middle of the air outlet.

[0021] Since the air sweeping blades near the two sides are more likely to produce condensation, it is necessary to appropriately increase the pores of the mesh structure of the air sweeping blades on both sides.

[0022] Furthermore, the distance between the air sweeping blades close to both sides of the air outlet and the side edges of the air outlet is 3-7 cm.

[0023] If the above distance is too close, the wind sweeping blades and the parts of the air outlet are likely to interfere with each other; if the above distance is too far, it will inevitably affect the wind sweeping effect.

[0024] A plurality of the above-mentioned sweeping blades are arranged at intervals at the air outlet of the indoor unit of the above-mentioned air conditioner, wherein the first connection part of the sweeping blade is rotatably connected to the indoor unit base, and the second connection parts of the above-mentioned plurality of sweeping blades are pivotally connected to the linkage rod, and the linkage rod drives the sweeping blades to swing synchronously.

[0025] The beneficial effects of the technical solution provided by this application include at least the following aspects:

[0026] The air sweeping blade and air conditioner obtained by the above design, when the air conditioner is running, hot air or cold air is blown out from the air outlet of the wall-mounted unit and swept by the air sweeping blade. Since the air sweeping blade adopts a mesh structure, the hot air or cold air can partially pass through the mesh structure, thereby reducing the direct blowing of the hot air or cold air on the air sweeping blade; thereby reducing condensation. In addition, since less condensation can be hung in the mesh holes of the mesh structure, the accumulation of condensation is reduced; preventing the condensation from accumulating into water droplets and flowing into the room.

[0029] 100 - wind sweeping blade; 110 - blade skeleton; 112 - main support rod; 114 - auxiliary support rod; 116 - outer frame; 120 - first connecting part; 130 - second connecting part; 140 - mesh structure. DETAILED DESCRIPTION

[0030] Please refer to Figure 1The present embodiment provides a wind sweeping blade 100, which is used to be installed at the air outlet of the wall-mounted machine to achieve left and right wind sweeping. Specifically, a plurality of wind sweeping blades 100 are evenly spaced and arranged on the base of the wall-mounted machine housing, and are movably connected to the base. The linkage rod can move left and right under the action of the driving mechanism, and the wind sweeping blades 100 can swing synchronously under the drive of the linkage rod, thereby achieving left and right wind sweeping. Since the base of the wall-mounted machine housing can directly adopt the structure in the prior art, in order to avoid redundancy, it will not be described in detail.

[0031] The wind sweeping blade 100 as a whole is similar to the bionic structure of a leaf, and includes a mesh structure 140 and a blade skeleton 110. The blade skeleton 110 provides support for the entire wind sweeping blade 100, and the mesh structure 140 is used for sweeping the wind. Specifically, the blade skeleton 110 includes an outer frame 116, a main support rod 112 and a plurality of auxiliary support rods 114, wherein the outer frame 116 constitutes the outer contour of the entire blade skeleton 110, which is similar to the contour shape of a leaf. The structure of the main support rod 112 and the plurality of auxiliary support rods 114 connected to the main support rod 112 is similar to the veins of a leaf. The first connecting portion 120 is a cylindrical structure, which is similar to the petiole of a leaf. An installation notch is provided on the outer frame 116, and the second connecting portion 130 is a pin structure, and is provided at the installation notch.

[0032] Further, along the extension direction of the secondary support rod 114, the cross-sectional dimension of the secondary support rod 114 gradually decreases; the extension direction of the secondary support rod 114 refers to the direction determined from the end of the secondary support rod connected to the main support rod 112 to the other end of the secondary support rod 114. And, along the extension direction of the main support rod 112, the cross-sectional dimension of the main support rod 112 gradually decreases; the extension direction of the main support rod 112 refers to the direction determined from the end of the main support rod 112 connected to the first connecting portion 120 to the end of the main support rod 112 connected to the second connecting portion 130. That is, the main support rod 112 and the secondary support rod 114 are both gradually tapering rods. For ease of description, the thick end is called the big end, and the thin end is called the small end. Among them, the big end of the main support rod 112 is connected to the first connecting portion 120, and the small end is connected to the second connecting portion 130. Furthermore, the secondary support rod 114 is also a gradually tapering rod, with a large end of the secondary support rod 114 connected to the main support rod 112 and a small end of the secondary support rod 114 connected to the outer frame 116 .

[0033] Since the main support rod 112 mainly bears the weight of the entire wind sweeping blade and drives the entire wind sweeping blade to swing, the main support rod 112 is relatively thick; the auxiliary support rod 114 is mainly used to fix the mesh surface of the mesh structure 140, and its design is relatively thin compared to the main support rod 112. The outer frame 116 is mainly used to fix the edge of the mesh structure 140, and its thickness is slightly greater than the thickness of the mesh structure 140. The main support rod 112 and the auxiliary support rod 114 adopt a structure with one end thick and the other end thin, which can effectively reduce the weight of the blade skeleton 110 while ensuring a certain strength of the blade skeleton 110; thereby making the blade skeleton 110 relatively light and convenient for flexible swinging.

[0034] Furthermore, the area occupied by the mesh structure 140 is controlled within a range of 30%-80%, preferably 60%. The area occupied refers to the value obtained by dividing the area of ​​the mesh structure 140 by the area of ​​the figure enclosed by the outline of the outer frame 116.

[0035] The above design enables the mesh structure 140 to effectively alleviate condensation while preventing the wind sweeping blade 100 from deforming. If the mesh structure 140 occupies too large an area, since the overall area of ​​the wind sweeping blade 100 is fixed, it will inevitably lead to a smaller blade skeleton 110; this will directly lead to a decrease in the overall strength of the wind sweeping blade, and the wind sweeping blade 100 is easy to deform. If the mesh structure 140 occupies too small an area, its effect of preventing condensation is not obvious, and it is difficult to fundamentally solve the problem of anti-drip.

[0036] Furthermore, the mesh number of the mesh structure 140 is 4-325 meshes, preferably 100-200 meshes. When the mesh size is too large, the air leakage is serious, which is not conducive to the effective air sweeping of the wind sweeping blade 100; when the mesh size is too small, the anti-condensation effect is not obvious. After a large number of experimental verifications, when the mesh number of the mesh structure 140 is between 4-325, it can not only meet the wind sweeping requirements, but also effectively reduce condensation. In this embodiment, a filter with a mesh size of 0.106mm and a standard mesh number of 140 is used, and the area of ​​a single grid is about 1.123x10-8 square meters. In other embodiments, the size of the mesh structure 140 can be selected from the following table.

[0037]

[0038] For ease of processing, the wind sweeping blade 100 in this embodiment is directly integrally injection molded. The use of the above process can also make the overall strength of the wind sweeping blade 100 higher. In other embodiments, the blade skeleton 110 and the mesh structure 140 may be processed separately and then detachably connected. In addition, the above-mentioned wind sweeping blade 100 may be made of metal, plastic or silk. In addition, in other embodiments, the blade skeleton 110 may only include an outer frame 116, without the main support rod 112 and the auxiliary support rod 114; or only the outer frame 116 and the main support rod 112 may be provided. The above-mentioned modified embodiments are all included in the protection scope of the present application.

[0039] Embodiment 2:

[0040] This embodiment provides an air conditioner, which includes a wall-mounted machine base, a linkage rod, and a plurality of wind sweeping blades 100 provided in Embodiment 1; wherein the wind sweeping blades 100 are evenly spaced on the base at the air outlet of the wall-mounted machine, and are movably connected to the base through a first connection portion 120. The linkage rod is also pivotally connected to the second connection portion 130 of the plurality of wind sweeping blades 100; and the linkage rod is parallel to the length direction of the base. When the linkage rod moves under the drive of the driving mechanism, it can drive the wind sweeping blades 100 to swing left and right to achieve wind sweeping.

[0041] Furthermore, among the above-mentioned multiple air sweeping blades 100, the pores of the mesh structure 140 of the air sweeping blades near the two sides of the air outlet are larger than the pores of the mesh structure 140 near the middle of the air outlet. Studies have found that the larger the pores of the mesh structure 140, the better its anti-condensation effect; and if the pores are too large, the air sweeping effect of the air sweeping blades will be reduced. In addition, the air sweeping blades on both sides of the air outlet of the wall-mounted unit are more prone to condensation. The above design can effectively improve the anti-condensation effect without affecting the air sweeping effect of the air sweeping blades in the middle.

[0042] In addition, in this embodiment, the distance between the sweeping blades on both sides of the air outlet and the side edge of the air outlet is controlled to be 3-7 cm. If the distance between the sweeping blades on both sides and the side edge of the air outlet is too close, the sweeping blades are likely to interfere with other parts of the air outlet when swinging; if the above distance is too far, the sweeping area of ​​the air conditioner is too small.

[0043] In other embodiments, the sweeping blade 100 in Embodiment 1 is installed on the leftmost or / and rightmost side of the wall-mounted unit base, and the sweeping blades in the prior art can be installed at other positions. The above air conditioners can effectively improve the condensation phenomenon.

[0044] The advantages of the air conditioner provided in this embodiment over the existing air conditioner include at least the following aspects:

[0045] When the air conditioner is running, hot air or cold air blows out from the air outlet of the wall-mounted unit and is swept by the sweeping blades. Since the sweeping blades adopt a mesh structure, the hot air or cold air can partially pass through the mesh structure, thereby reducing the direct blowing of the hot air or cold air on the sweeping blades; thus, condensation can be reduced. In addition, since less condensation can be hung in the mesh holes of the mesh structure, the accumulation of condensation is reduced; preventing condensation from accumulating into water droplets and flowing into the room.

[0046] It should be noted that the directional terms such as "left" or "right" mentioned in this application refer to the left and right when a person faces the wall-mounted unit.

[0047] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various modifications without departing from the spirit and scope of the present invention, and the above modifications are all within the protection scope of the present invention.
