Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of air conditioning equipment, and in particular to a counterweight, a pipeline, a pipeline counterweight assembly and an air conditioner. Background Art
[0002] Air conditioning noise affects the user experience, especially the low-frequency noise caused by the air conditioning compressor and its pipeline system. Some related technologies use counterweights clamped on the pipeline to solve the noise problem, that is, the counterweights are used to apply gravity to the pipeline to change its natural frequency, thereby improving the resonance noise of the pipeline. However, the counterweights are usually eccentric structures. During the vibration of the pipeline, the angle of the counterweights can easily shift, thereby shifting the natural frequency of the pipeline and causing the resonance noise of the pipeline to deteriorate.

[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0025] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0026] like Figures 1 to 4 As shown, the present disclosure exemplarily provides a counterweight 1, specifically, the counterweight 1 includes a mounting hole 11 and a first anti-rotation structure 12. The counterweight 1 is commonly constructed in a cylindrical shape, and can be sleeved on the pipeline 2. And the counterweight 1 is usually an eccentric structure, that is, by reasonably setting the center of gravity of the counterweight 1, the natural frequency of the pipeline 2 can be changed, the resonance of the pipeline can be avoided, and the vibration noise can be reduced. In other words, whether the vibration noise can be effectively avoided is related to the center of gravity of the counterweight 1, and the optimal position of the counterweight can be determined by, for example, simulation tests. If the counterweight 1 rotates due to the vibration of the pipeline 2, the counterweight will be offset from the preferred position, thereby causing noise.
[0027] The counterweight 1 provided in the present disclosure is provided with a mounting hole 11 and a first anti-rotation structure 12, wherein the mounting hole 11 is suitable for the pipeline body 21 to pass through, and the first anti-rotation structure 12 is suitable for cooperating with the second anti-rotation structure 22 provided on the pipeline body 21 to limit the circumferential rotation of the counterweight 1. That is, through the cooperation of the first anti-rotation structure 12 and the second anti-rotation structure 22, the circumferential rotation of the counterweight 1 can be limited. The circumferential rotation of the counterweight 1 is constrained, which means that the center of gravity determined according to experiments, etc. will not be offset, thereby avoiding changes in the natural frequency of the pipeline 2, and then avoiding resonance of the pipeline, which is conducive to reducing the resonance noise of the pipeline.
[0028] It should be noted that, in order to make the description more complete and clear, the pipeline body 21 and the second anti-rotation structure 22 provided on the pipeline body 21 are introduced as environmental features and do not constitute a limitation on the protection scope of the counterweight 1, that is, the counterweight 1 provided with the mounting hole 11 and the first anti-rotation structure 12 is protected as an independent component, and its manufacture and sales are not restricted by the pipeline 2. Similarly, in the topic of introducing the pipeline 2 later, the counterweight 1 is also introduced as an environmental feature and does not constitute a limitation on the protection scope of the pipeline 2.
[0029] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the counterweight 1 provided by the present disclosure is provided with a first anti-rotation structure 12, wherein the first anti-rotation structure 12 is configured to cooperate with a second anti-rotation structure 22 provided on the pipeline body 21 to limit the circumferential rotation of the counterweight 1. In this way, the counterweight 1 will not rotate accidentally even under the vibration of the pipeline 2, thereby avoiding the displacement of the preset center of gravity, and further avoiding the change of the natural frequency of the pipeline 2, which is conducive to reducing the low-frequency noise caused by the pipeline 2.
[0030] The present disclosure does not limit the specific implementation of the first anti-rotation structure 12 and the second anti-rotation structure 22 , and any structure or method that can cooperate with each other to achieve circumferential limitation can be applied to the present disclosure.
[0031] like Figure 1 and Figure 2 As shown, the first anti-rotation structure 12 is an anti-rotation hole, which is formed by protruding outward from the mounting hole 11. For example, two interconnected holes, one large and one small, can be formed on the counterweight 1, wherein the larger hole serves as the mounting hole 11 and matches the shape of the pipeline body 21 for the pipeline body 21 to pass through, and the smaller hole serves as the first anti-rotation structure 12. Correspondingly, the second anti-rotation structure 22 is a protrusion arranged on the outer periphery of the pipeline body 21. After the counterweight 1 is assembled to the pipeline 2, the second anti-rotation structure 22, which is constructed as a protrusion, is inserted into the first anti-rotation structure 12, which is constructed as an anti-rotation hole, and plays a role of circumferential limiting. In the figure, the anti-rotation hole is constructed in a semicircular shape, and correspondingly, the protrusion is constructed as a semicircular protrusion.
[0032] The counterweight 1 is made of an elastic material, for example, the counterweight 1 is made of a rubber material. The counterweight 1 is provided with a notch 13 extending from the outer edge of the counterweight 1 to the mounting hole 11, and the width of the notch 13 is smaller than the diameter of the mounting hole 11. Specifically, the width of the notch 13 is smaller than the diameter of the mounting hole 11, so that after the counterweight 1 is assembled on the pipeline 2, the pipeline 2 will not fall out of the mounting hole 11 without being acted upon by external forces. The counterweight 1 is made of an elastic material and combined with the notch 13. During the assembly process, it is only necessary to overcome the elastic force to open the notch 13, insert the pipeline 2 into the mounting hole 11, and make the first anti-rotation structure 12 and the second anti-rotation structure 22 cooperate. Under the action of the elastic restoring force, the notch 13 is closed, and finally the counterweight 1 is assembled on the pipeline 2. This structure enables the counterweight 1 to be assembled when the pipeline 2 has been arranged, and the installation is convenient and more versatile.
[0033] In addition, if Figure 1 As shown, the outer periphery of the counterweight 1 is provided with a receiving groove 14 along the circumferential direction. The receiving groove 14 is used to receive the binding member. The binding band may be a rubber ring, for example, so that the counterweight 1 can be more securely assembled on the pipeline 2.
[0034] like Figure 3 As shown, according to the second aspect of the embodiment of the present disclosure, a pipeline 2 is also provided, which can cooperate with any of the above-mentioned counterweights 1 to prevent the counterweight 1 from rotating circumferentially, and the pipeline 2 includes a pipeline body 21 and a second anti-rotation structure 22 arranged on the outer periphery of the pipeline body 21. In the above-mentioned embodiment in which the first anti-rotation structure 12 is configured as an anti-rotation hole, the second anti-rotation structure 22 is a protrusion. Of course, in some other embodiments, when the first anti-rotation structure 12 is configured as a protrusion, the corresponding second anti-rotation structure 22 is an anti-rotation hole.
[0035] Taking the second anti-rotation structure 22 as a protrusion as an example, in some embodiments, the second anti-rotation structure 22 is formed by the wall of the pipeline body 21 protruding outward, and the cavity formed inside the second anti-rotation structure 22 after the protrusion is connected to the pipeline body 21. That is, the second anti-rotation structure 22 forms a cavity inside while forming a protrusion for anti-rotation, and the cavity is connected to the pipeline body 21. This structure is conducive to increasing the cross-sectional flow rate of the pipeline 2 at this position. In other embodiments, the second anti-rotation structure 22 is integrally formed on the outer wall surface of the pipeline body 21 by welding. That is, different from the first method of forming the second anti-rotation structure 22 mentioned above, in this other embodiment, the second anti-rotation structure 22 can be additionally provided according to actual needs, which is conducive to improving the flexibility of assembly.
[0036] like Figure 4 As shown, according to the third aspect of the embodiment of the present disclosure, there is also provided a pipeline counterweight assembly, comprising any one of the above counterweights 1 and any one of the above pipelines 2, and having all the beneficial effects thereof, which will not be repeated here.
[0037] Furthermore, the second anti-rotation structure 22 extends along the length direction of the pipeline body 21, and the extension length of the second anti-rotation structure 22 is greater than the axial length of the counterweight 1, which makes the first anti-rotation structure 12 and the second anti-rotation structure 22 have sufficient contact area, thereby improving the reliability of the circumferential anti-rotation of the counterweight.
[0038] According to a fourth aspect of the embodiment of the present disclosure, an air conditioner is also provided, comprising the above-mentioned pipeline counterweight assembly. The air conditioner may be, for example, an outdoor unit of an air conditioner, and the pipeline counterweight assembly provided by the present disclosure is beneficial to reducing the low-frequency noise of the air conditioner compressor.

In addition to the orientation depicted in the drawings, such spatially relative terms are also intended to include different orientations of the device in use or operation. For example, if the device in the drawings is turned over, the element described as being "above" or "upper" relative to another element will be "below" or "lower" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" includes both upper and lower orientations. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.
[0045] In addition, the word "exemplary" is used herein to indicate serving as an example, instance, or diagram.
