Description

Technical Field

[0001] The present disclosure relates to the technical field of pipeline fixing, and particularly to a pipeline fixing device and a household electrical appliance. Background Art

[0002] In equipment involving liquid working medium, a large number of pipelines are usually arranged. In the case where the stiffness of some pipelines is weak or the electrical components supported by the pipelines are heavy, the pipelines are likely to break during transportation and operation.

[0003] Currently, the method of using pipe clamps is mostly adopted to fix the pipelines with weak stiffness to the adjacent pipelines with strong stiffness. These pipe clamps in the related art usually adopt rubber materials. To ensure that the pipe clamps do not loosen after assembly, wire ties are mostly fixed on the outer side of the pipe clamps. However, the wire ties are prone to aging and loosening, so that the pipe clamps lose the protection effect and the reliability is poor. Utility Model Content

[0004] To overcome the problems existing in the related art, the present disclosure provides a pipeline fixing device and a household electrical appliance.

[0005] According to the first aspect of the embodiments of the present disclosure, a pipeline fixing device is provided, including:

Among them, the connecting portion is detachably connected to the main body, and the pre-tightening portion and the inner wall of the mounting hole clamp the pipeline from both sides respectively.

[0009] Optionally, the pre-tightening portion is configured as an arc-shaped plate capable of fitting the outer peripheral wall of the pipeline.

Detailed implementation mode

[0028] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation modes described in the following exemplary embodiments do not represent all the implementation modes consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] As Figures 1 to 3 shown, according to an exemplary embodiment of the present disclosure, a pipeline fixing device 100 is provided. The present disclosure is not intended to limit the scope of use of the pipeline fixing device 100. Any household electrical appliance that needs to fix the pipeline to prevent the pipeline 200 from deforming or breaking during transportation and operation, such as, for example, the outdoor unit of an air conditioner, a washing machine, a dehumidifier, or a refrigerator, etc., can apply the pipeline fixing device 100 provided by the present disclosure to solve technical problems.

[0030] Specifically, the pipeline fixing device 100 provided by the present disclosure includes a main body 1 and a preloading member 2. Among them: The main body 1 is provided with a plurality of mounting holes 11 for the pipeline 200 to pass through; the preloading member 2 is detachably arranged in the mounting hole 11, and the preloading member 2 is configured to be able to provide a preloading force against the inner wall of the mounting hole 11 to the pipeline 200.

[0031] For the convenience of description, hereinafter, the pipeline fixing device 100 provided by the present disclosure is used for the support and fixation of the pipeline 200 inside the outdoor unit of an air conditioner as an example for exemplary illustration. Without special explanation, the pipeline 200 includes an expansion valve pipeline and a condenser pipeline.

[0032] As Figure 4 shown in the air conditioner, the electronic expansion valve 300 usually has a relatively large self-weight, and the diameter of the electronic expansion valve pipeline supporting the electronic expansion valve 300 is small and the stiffness is weak. The pipeline 200 is prone to deformation, resulting in the situation of pipe collision, and during transportation, due to the vibration generated by road bumps, or during operation, the vibration generated by the whole machine, may cause the electronic expansion valve pipeline to break.

[0033] The main body 1 of the pipeline fixing device 100 of the present disclosure plays a role in supporting and fixing the pipeline 200. The main body 1 is provided with a plurality of mounting holes 11. For example, Figure 1Shown as being provided with two mounting holes 11, one of the mounting holes 11 is used to mount and fix the electronic expansion valve pipeline. For example, it can be a high-pressure pipe connecting the expansion valve. Considering that the condenser pipeline is relatively close to the electronic expansion valve pipeline and the condenser pipeline is mostly arranged in the form of a tube bundle, its stiffness is relatively large. By connecting the electronic expansion valve pipeline to the condenser pipeline through the pipeline fixing device 100 in the present disclosure, it can be regarded as binding the electronic expansion valve pipeline to the condenser pipeline, thereby improving the stiffness of the electronic expansion valve pipeline by means of the stiffer condenser pipeline.

[0034] This requires a reliable connection between the pipeline fixing device 100 and the pipeline 200 to avoid losing the supporting and fixing effect due to the loosening of the pipeline fixing device 100. In some related technologies, a way of fixing a wire tie outside the main body 1 is adopted. For example, an elastic rubber ring is tied. Through the elastic force of the inward contraction of the elastic rubber ring, the pipeline 200 is maintained in the mounting hole 11. Although the way of the wire tie is convenient to operate, after long-term use, the wire tie is prone to aging and loosening, so that the pipeline fixing device 100 loses the protection effect and has poor reliability.

[0035] Considering the above technical problems, a pre-tightening member 2 is detachably arranged in the mounting hole 11 in the present disclosure. The detachable setting of the pre-tightening member 2 is convenient for maintenance and replacement on the one hand, and on the other hand, enables the pre-tightening member 2 to be installed after the pipeline 200 is assembled, avoiding interference of the pre-tightening member 2 with the installation of the pipeline 200. The pre-tightening member 2 is configured to be able to provide a pre-tightening force against the inner wall of the mounting hole 11 to the pipeline 200, thereby maintaining the pipeline 200 in the mounting hole 11.

[0036] It should be noted that the pre-tightening force refers to the force applied to the component in advance. This force is usually used to ensure the close contact between the connecting parts and prevent loosening. In addition, providing the pre-tightening force here can be either elastic abutment or rigid extrusion, and there is no limitation on this. The existence of this pre-tightening force improves the assembly stability between the pipeline fixing device 100 and the pipeline 200, and the pre-tightening member 2 is arranged inside the mounting hole 11. Even after long-term use, it is not easy to age and loosen like the wire tie in the related technology, which is beneficial to improving the reliability of the protection of the pipeline 200 by the pipeline fixing device 100 during the transportation and operation of the equipment.

[0037] Continue to refer to Figures 1 to 3, in some embodiments, the pre-tightening member 2 includes a connecting portion 21 and a pre-tightening portion 22. The pre-tightening member 2 can be constructed as an integral structural member. For example, the connecting portion 21 and the pre-tightening portion 21 are integrally injection-molded, which is beneficial to improving the overall structural stiffness of the pre-tightening member 2. Among them, the connecting portion 21 is detachably connected to the main body 1. Specifically, the connecting portion 21 is detachably connected to the inner wall of the mounting hole 11. The pre-tightening portion 21 and the inner wall of the mounting hole 11 clamp the pipeline 200 from both sides respectively. That is, the pre-tightening portion 21 and the inner wall of the mounting hole 11 can be regarded as two clamping arms.

[0038] Optionally, the pre-tightening portion 22 can be constructed as an arc-shaped plate that can fit the outer peripheral wall of the pipeline 200. According to the different diameters of the pipelines 200 to be fixed, the mounting holes 11 on the main body 1 can be constructed with different diameters. The arc-shaped pre-tightening portion 22 can be adaptively designed according to the diameter of the pipeline 200, and the arc-shaped pre-tightening portion 22 can increase the contact area with the pipeline 200, further improving the reliability of fixing the pipeline 200.

[0039] A notch 12 communicating with the mounting hole 11 can be provided on the main body 1 to facilitate assembling the main body 1 onto the pipeline 200 from the notch 12. By providing the notch 12 on the main body 1, it is possible to assemble the pipeline fixing device 100 after the electronic expansion valve 300 and its pipelines are installed, and during later maintenance, it is not necessary to first remove the electronic expansion valve 300 and its pipelines. This is different from the method in which the notch 12 is not provided and thus the pipeline fixing device 100 needs to be installed from the starting end of the pipeline 200 first, and then the electronic expansion valve 300 and its pipelines are installed in the air conditioner. It is beneficial to improve the installation efficiency of the pipeline fixing device 100.

[0040] In some embodiments, as Figure 2 described, the pre-tightening portion 22 extends to at least partially block the notch 12, which makes the clamp opening D2 formed by the pre-tightening portion 22 smaller than the diameter of the pipeline 200, thereby preventing the pipeline 200 from slipping out of the mounting hole 11. In these embodiments, the pre-tightening member 2 can not only provide the function of pre-tightening force but also play the role of at least partially closing the notch 12. In other embodiments, the opening width D1 of the notch 12 is greater than or equal to the diameter of the pipeline 200, that is, the opening width of the notch 12 is large enough so that the main body 1 can be more easily assembled onto the pipeline 200.

[0041] To achieve the detachable connection between the pre-tightening member 2 and the mounting hole 11, as Figure 3As shown, an installation groove 111 for accommodating the connection part 21 is provided on the inner wall of the installation hole 11. The installation groove 111 extends along the axial direction of the installation hole 11. Among them, a limiting structure is provided between the groove wall of the installation groove 111 and the connection part 21 to limit the displacement of the pre-tightening part 2 along the axial direction of the installation hole 11. Here, the axial direction along the installation hole 11 is the installation direction of the pre-tightening part 2. The limiting structure can limit the pre-tightening part 2 in the axial direction of the installation hole 11. Without sufficient external force to remove the pre-tightening part 2, the pre-tightening part 2 can be firmly arranged in the installation hole 11, which further improves the reliability of the protection of the pipeline 200 by the pipeline fixing device 100 during the transportation and operation of the equipment.

[0042] The present disclosure does not aim to limit the specific form of the limiting structure. Any structure or method capable of realizing the axial limiting of the pre-tightening part 2 along the installation hole 11 can be applied to the present disclosure. In some embodiments, the limiting structure may include a limiting protrusion 112 and a limiting groove 211. Among them, the limiting protrusion 112 is provided on one of the connection part 21 and the groove wall of the installation groove 111, and the limiting groove 211 is provided on the other of the connection part 21 and the groove wall of the installation groove 111, and the limiting groove 211 and the limiting protrusion 112 are arranged in cooperation. Among them, Figure 3 It is shown that the limiting protrusion 112 is provided on the groove wall of the installation groove 111, and the limiting groove 211 is provided on the connection part 21.

[0043] Multiple limiting protrusions 112 may be provided. The multiple limiting protrusions 112 are at least distributed on two groove walls of the installation groove 111 opposite to each other, which is beneficial to improving the stability of the limiting cooperation of the limiting structure and preventing the pre-tightening part 2 from loosening from the installation hole 11 during the operation of the equipment. The limiting protrusion 112 can be constructed as a protrusion with an arc-shaped cross-section, and the limiting groove 211 is constructed as a groove with an arc-shaped cross-section, so as to reduce the resistance during installation and removal. In some other embodiments, an elastic snap-fit structure, etc. can also be applied to the present disclosure to achieve axial limiting along the installation hole 11, which will not be elaborated here.

[0044] Furthermore, both ends of the installation groove 111 can extend to the end face of the main body 1. Here, both ends of the installation groove 111 are Figure 3 the up-and-down direction of the drawing. This enables the pre-tightening part 2 to be installed on both sides of the main body 1. Since the installation direction does not need to be considered, it is beneficial to improve the assembly efficiency of the pre-tightening part 2.

[0045] The pipeline fixing device 100 provided by the present disclosure can be made of a hard plastic material, such as plastic materials like ABS. Compared with a rubber pipe clamp, the pipeline fixing device 100 made of a plastic material can provide greater stiffness, thereby improving the support and fixing effect on the pipeline 200.

[0046] According to the second aspect of the embodiments of the present disclosure, as Figure 4 shown, there is also provided a household electrical appliance, including the pipeline fixing device 100 of any one of the above. The household electrical appliance includes, but is not limited to, an outdoor unit of an air conditioner, a washing machine, a dehumidifier, a refrigerator or other devices that require pipeline layout.

[0047] Next, with Figures 1 to 4 the outdoor unit of an air conditioner as an example, a usage method of the pipeline fixing device 100 provided by the present disclosure will be exemplarily introduced.

[0048] An electronic expansion valve 300 and a condenser 400 are provided inside the air conditioner. The electronic expansion valve 300 is connected with an electronic expansion valve pipeline, and the condenser 400 is connected with a condenser pipeline. The opening width D1 of the notch 12 communicating with the mounting hole 11 on the main body 1 is greater than the diameter of the pipeline 200, so that the main body 1 of the pipeline fixing device 100 can be more easily assembled onto the electronic expansion valve pipeline and the condenser pipeline. Then, the connecting portion 21 of the pre-tightening member 2 is aligned with the mounting groove 111 in the mounting hole 11 and inserted to a predetermined position. At this time, the pre-tightening portion 22 of the pre-tightening member 2 partially blocks the notch 12, and the formed pipe clip opening D2 is smaller than the diameter of the pipeline 200, so that the pipeline 200 can be prevented from slipping out of the mounting hole 11. When disassembling, the reverse steps can be followed. First, the pre-tightening member 2 is removed from the mounting hole 11, and then the main body 1 is separated from the pipeline 200, which will not be elaborated here.
