Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an air conditioner sweep blade structure. Background Technology

[0002] The indoor unit of an air conditioner is equipped with a sweeping blade assembly, which rotates the sweeping blades via a connecting rod to adjust the airflow direction. Most existing sweeping blade assemblies use a combination of sweeping blades and a connecting rod, but this is difficult to install and carries the risk of detachment. Another approach is to add a separate positioning drive blade after merging the sweeping blades and the connecting rod; however, this additional positioning drive blade also requires installation and carries the risk of detachment.

[0003] To address the difficulties in installing the connecting rod and the sweeping blades, which pose a risk of detachment, related technologies have provided integrated air conditioning sweeping blade assemblies, such as the Chinese utility model patent entitled "An Integrated Air Conditioning Sweeping Blade Structure" with patent publication number CN218672595U. In this patent, the connecting rod is connected to the blade side plate. Although this patent solves the problem of difficult installation of the connecting rod and the sweeping blades, the limiting structure used to limit the blades may fail due to deformation during operation.

Specific implementation examples:

[0040] Please refer to Figures 1 to 4 As shown, this embodiment provides an air conditioner sweep blade structure, including several blades 1, connecting rods 2 and base plate 3;

[0041] One end of the connecting rod 2 is provided with a limiting structure 4, which includes a limiting member 41 and a first inclined rib 421.

[0042] The limiting member 41 includes a hollow part 411, and a first plate surface 412 and a second plate surface 413 located on the upper and lower sides of the hollow part 411.

[0043] The first diagonal rib 421 is disposed in the hollow part 411, and its two ends are respectively connected to the first plate surface 412 and the second plate surface 413;

[0044] The blade 1 is connected to the side of the connecting rod 2 and the upper surface of the base plate 3 respectively, and the blade 1, the connecting rod 2 and the base plate 3 are integrally formed.

[0045] In this embodiment, several blades 1, connecting rods 2, and a base plate 3 are integrally formed, with the blades 1 connected to the connecting rods 2 and the base plate 3 respectively. One end of the connecting rod 2 is connected to a limiting structure 4 for limiting the blades. This limiting structure 4 includes a limiting member 41 connected to the end of the connecting rod 2, and a first inclined rib 421 disposed in the hollow portion 411 of the limiting member 41 and connecting the first plate surface 412 and the second plate surface 413 of the limiting member 41. The first inclined rib 421 maintains the structure of the hollow portion 411 of the limiting member 41, that is, the first inclined rib 421 provides support for the first plate surface 412 and the second plate surface 413, thereby maintaining the distance between them and improving the reliability of the limiting structure 4. Therefore, when using the air conditioning sweeping blade structure provided in one or more embodiments of this application, it can be ensured that the limiting structure will not fail to effectively limit the blades.

[0046] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the limiting structure 4 further includes a second inclined rib 422, the two ends of which are respectively connected to the first plate surface 412 and the second plate surface 413.

[0047] More specifically, in this embodiment, such as Figure 1 and Figure 2 As shown, the first oblique rib 421 and the second oblique rib 422 are symmetrically arranged in the hollow portion 411; furthermore, one end of the first oblique rib 421 and the second oblique rib 422 intersects the second plate surface 413, so that the first oblique rib 421 and the second oblique rib 422 are combined to form a V-shaped structure.

[0048] In this embodiment, the first oblique rib 421 is set to tilt to the upper left, and the second oblique rib 422 is set to tilt to the upper right. The first oblique rib 421 and the second oblique rib 422 intersect at the second plate surface 413. That is, the first oblique rib 421 and the second oblique rib 422 are combined in the hollow part 411 to form a V-shaped structure. This allows for the setting of a smaller number of oblique ribs while ensuring the stability between the limiting member 41, the first oblique rib 421 and the second oblique rib 422.

[0049] It should be noted that in some other embodiments, the first oblique rib 421 can be configured to slope upward to the right, and the second oblique rib 422 can be configured to slope upward to the left, with the first oblique rib 421 and the second oblique rib 422 intersecting at the first plate surface 412; the first oblique rib 421 and the second oblique rib 422 can also be symmetrically intersecting, so that the first oblique rib 421 and the second oblique rib are combined to form an X-shaped structure; it may also include multiple sets of first oblique ribs 421 and second oblique ribs 422 combined to form a V-shaped structure or an X-shaped structure.

[0050] Please refer to this again. Figure 2As shown, in this embodiment, the blade 1 includes a sweeping part 11. One side of the sweeping part 11 is recessed from the outer edge toward the inner side to form an opening 111. A connecting rod 112 extends from the bottom end of the opening 111 toward the outer side in the middle of the opening 111. The connecting rod 2 is connected to the connecting rod 112.

[0051] As a preferred embodiment, please refer to the following carefully. Figure 1 As shown, in this embodiment, the length of the connecting rod 112 protruding from the bottom of the opening 111 is less than the distance from the bottom of the opening 111 to the outer edge of the sweeping part 11.

[0052] Please refer to Figures 1 to 3 As shown, in this embodiment, the blade 1 further includes a connecting part 12, one end of which is connected to the side of the sweeping part 11 without an opening, and the base plate 3 is connected to the other end of the connecting part 12.

[0053] In this embodiment, the blade 1 includes a sweeping part 11 and a connecting part 12. The sweeping part 11 has an opening 111 on one side and a connecting rod 112 for connecting to one side of the connecting rod 2 is formed in the opening 111. The length of the connecting rod 112 is less than the depth of the opening 111. Thus, after the connecting rod 2 is connected to the connecting rod 112 on one side, there is a gap between the connecting rod 2 and the sweeping part 11 of the blade 1, which makes it convenient for the connecting rod 2 to drive the blade 1 to swing.

[0054] Please refer to Figure 1 As shown, in this embodiment, a baffle 21 is also provided on the connecting rod 2. The baffle 21 extends from the lower surface of the connecting rod 2 toward the base plate 3 and is located between the limiting structure 4 and the blade 1. The distance from the bottom end of the baffle 21 to the upper surface of the base plate 3 is less than the distance from the locking block 43 to the upper surface of the base plate 3.

[0055] In this embodiment, a baffle 21 is provided on the connecting rod 2 located between the limiting structure 4 and the blade 1, extending from the lower surface of the connecting rod 2 toward the base plate 2. The height of the baffle 21 is greater than the height of the protrusion 23. Thus, even if all the locking blocks 23 in the limiting structure 4 pass through the perforations opened on the inner wall in the width direction of the air outlet of the air conditioner, the baffle 23 cannot pass through the perforations, which further limits the blade 1.

[0056] As a preferred embodiment, please refer to Figures 1 to 4As shown, the limiting member 41 is a U-shaped member, the end of the connecting rod 2 is placed at the opening of the U-shaped member and connected to the opening, a hollow portion 411 is defined between the upper and lower plates of the U-shaped member, the inner surface of the upper plate of the U-shaped member is the first plate surface 412, and the inner surface of the lower plate of the U-shaped member is the second plate surface 413; the limiting mechanism 4 also includes a plurality of locking blocks 43, which are spaced apart on the outer surface of the lower plate of the U-shaped member.

[0057] In this embodiment, a perforation is provided on the inner wall of the air outlet in the width direction of the air conditioner. The limiting structure 4 passes through the perforation. In addition, multiple locking blocks 43 are spaced apart on the outer surface of the lower plate of the U-shaped part. Each pair of adjacent blocks forms a limiting groove for limiting the locking part of the perforation. After the air conditioner sweeping blade structure provided in this embodiment is installed in the air conditioner, the limiting structure 4 passes through the perforation and the locking part of the perforation is located in the limiting groove. During the operation of the air conditioner, since the first inclined rib 421 and the second inclined rib 422 can maintain the distance between the upper and lower plates of the U-shaped part, it can be ensured that the limiting structure 4 will not be completely placed in the perforation for a long time, but will only pass through the perforation when the connecting rod 2 is pushed and needs to move, or fall out of the perforation. That is, during the operation of the air conditioner, the deformation of the limiting mechanism 4 when the connecting rod 2 is not under force cannot allow the limiting structure 4 to pass through the perforation, thus improving the reliability of the limiting structure 4. In this embodiment, the upper and / or lower surfaces of the U-shaped member can be further configured as elastic members so that the limiting mechanism 4 can pass through the perforation when the connecting rod 2 is subjected to a thrust.

[0058] Please refer to Figure 3 and Figure 4 As shown, a plurality of first positioning blocks 31 and second positioning blocks 32 are provided on the lower plate surface of the base plate 3, and the first positioning blocks 31 and second positioning blocks 32 are further disposed on both sides of the base plate 2.

[0059] In a preferred embodiment, for greater structural stability, at least one first positioning block 32 and a second positioning block 33 are provided on the side of the base plate 3 away from the blade 1, i.e., on the lower surface of the base plate 3. At least one first connecting hole and a second connecting hole are provided on the side of the air conditioner casing near the base plate 3. The first positioning block 32 is disposed in the first connecting hole, and the second positioning block 33 is disposed in the second connecting hole. The first positioning block 32 is engaged with the first connecting hole, and the second positioning block 33 is engaged with the second connecting hole.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
