Description

Technical Field

[0001] The present application belongs to the technical field of HVAC equipment, and specifically relates to a pipeline connection structure, an outdoor unit and HVAC equipment. Background Art

[0002] At present, a compressor is usually installed in the outdoor unit of HVAC equipment. Pipes (such as high / low pressure valve pipelines) are connected between the compressor and the heat exchanger. The high / low pressure valve pipelines need to be installed and fixed through the gaps in the sheet metal of the outdoor unit. When the compressor vibrates, the vibration will be transmitted to the sheet metal of the outdoor unit through the high / low pressure valve pipelines, and vibration noise will be generated, affecting the user experience. Utility Model Content

[0003] The purpose of the present application is to at least solve the problem that when the compressor is running, the connecting pipe connected to the compressor transmits vibration to the sheet metal of the outdoor unit and generates vibration noise. This purpose is achieved by the following methods:

[0004] The first aspect of the present application proposes a pipeline connection structure, including: a fixed plate, provided with a first installation notch; a vibration isolation member, the vibration isolation member is provided with a limiting groove, the vibration isolation member is plugged into and matched with the fixed plate through the limiting groove, and blocks at least part of the first installation notch, and the vibration isolation member is provided with a mounting hole, at least part of the mounting hole is located in the first mounting notch, and the mounting hole is used to accommodate part of the connecting pipeline.

[0005] The pipeline connection structure provided according to the first aspect of the present application is used to install and fix the connecting pipeline, and the connecting pipeline is used to be connected to the equipment parts that generate vibration during operation, such as the compressor. By opening a first installation notch on the fixed plate, the vibration isolation member is plugged into the fixed plate through the limiting groove. When installing the connecting pipeline of the compressor, part of the connecting pipeline is first accommodated in the mounting hole of the vibration isolation member so that part of the vibration isolation member is wrapped around the outer peripheral side of the connecting pipeline, and then the vibration isolation member is installed at a position corresponding to the first installation notch to cover at least part of the installation notch, so that after the vibration isolation member is assembled and connected to the fixed plate, part of the connecting pipeline and the vibration isolation member can be accommodated in the first installation notch. Since the vibration isolation member is plugged into the fixed plate through the limiting groove, it can play a role along the mounting hole. The vibration isolator has a limiting effect on the axial direction, so that when the mounting hole covers part of the connecting pipeline, it can restrain the connecting pipeline. When the connecting pipeline is driven by the vibration of the compressor and other equipment to generate vibration force along its axial direction, the vibration isolator can limit the connecting pipeline along the axial direction of the connecting pipeline, and can perform buffering and vibration isolation when it is subjected to the axial vibration force generated by the connecting pipeline, thereby achieving axial vibration isolation for the connecting pipeline. Moreover, since part of the vibration isolator is wrapped around the outer peripheral side of the connecting pipeline, there is no contact between the connecting pipeline and the fixing frame, which can further play a radial vibration isolation role for the connecting pipeline, thereby reducing the risk of vibration noise between the connecting pipeline and the fixing frame caused by the vibration of the compressor, thereby improving the user experience.

[0036] The present application proposes a HVAC device, which may be an air conditioner, a multi-split unit, a heat pump, or other equipment used for heating or cooling. For ease of description, the present application only takes the HVAC device as an air conditioner as an example for illustration.

[0037] See also Figure 5 The air conditioner provided in the embodiment of the present application includes an outdoor unit 1000, and the outdoor unit 1000 includes a casing, a compressor (not shown in the figure) and a pipe connection structure 100. The casing includes a bottom plate 301 and a side plate 302 arranged around the bottom plate 301, and a second installation notch is provided at the bottom of the side plate 302; the compressor is arranged in the casing, and the compressor is provided with a connecting pipe 200; the fixing plate 10 of the pipe connection structure 100 is fixedly connected to the bottom plate 301 and shielded in the second installation notch, and the connecting pipe 200 of the compressor is installed on the fixing plate 10 through the vibration isolation member 20.

[0038] See also Figures 1 to 4 According to some embodiments of the present application, the pipeline connection structure 100 proposed in the present application includes a fixing plate 10 and a vibration isolation member 20 .

[0039] Specifically, the fixing plate 10 is provided with a first installation notch 11, and the first installation notch 11 is used to accommodate the connecting pipeline 200 of the compressor. The vibration isolator 20 defines a limiting groove 26, and the vibration isolator 20 is plugged and matched with the fixing plate 10 through the limiting groove 26, and blocks at least part of the first installation notch 11, and the vibration isolator 20 is provided with a mounting hole 24, at least part of the mounting hole 24 is located in the first installation notch 11, and the mounting hole 24 is used to accommodate part of the connecting pipeline 200.

[0040] In this embodiment, exemplarily, the fixing plate 10 is a sheet metal part, and the shape of the fixing plate 10 includes but is not limited to any one of a rectangular shape, a square shape and a U shape.

[0041] In some embodiments, the fixing plate 10 is rectangular, the length direction of the fixing plate 10 extends in the vertical direction, and the width direction of the fixing plate 10 extends in the horizontal direction. The first installation notch 11 is opened on one side of the width direction of the fixing plate 10, and the first installation notch 11 can be set in the horizontal direction, or can be set to be inclined upward or downward relative to the horizontal plane.

[0042] It can be understood that the vibration isolator 20 is a flexible component such as rubber, plastic or silicone, which can be elastically deformed when subjected to force.

[0043] Specifically, the size of the mounting hole 24 is not larger than the diameter of the connecting pipe 200 of the compressor, that is, it can be the same as the diameter of the connecting pipe 200, or slightly smaller than the diameter of the connecting pipe 200, so that when the connecting pipe 200 is located in the mounting card, the inner surface of the mounting hole 24 can wrap the connecting pipe 200.

[0044] In some embodiments, see Figure 1 and Figure 2 The vibration isolator 20 is provided with an opening 25, which is opened on one side of the vibration isolator 20 and communicates with the mounting hole 24. When the connecting pipe 200 of the compressor is installed into the mounting hole 24 from the opening 25, the region where the opening 25 of the vibration isolator 20 is located can undergo a certain elastic deformation when a force is applied, so that the connecting pipe 200 of the compressor can be installed into the mounting hole 24 through the opening 25, and the opening 25 can be restored to the initial state, thereby reducing the risk of the connecting pipe 200 being separated from the mounting hole 24.

[0045] The pipeline connection structure provided in the present application is used to install and fix the connecting pipeline 200. The connecting pipeline 200 is used to be connected to a device that generates vibration during operation, such as a compressor. By opening a first installation notch 11 on the fixing plate 10, the vibration isolator 20 is plugged into the first installation notch 11 through a limiting groove 26. The vibration isolator 20 has a mounting hole 24 and an opening 25 connected to the mounting hole 24. When installing the connecting pipeline 200 of the compressor, a portion of the connecting pipeline 200 is first installed in the mounting hole 24 of the vibration isolator 20 through the opening 25, so that a portion of the vibration isolator 20 is wrapped around the outer peripheral side of the connecting pipeline 200, and then the vibration isolator 20 is installed at a position corresponding to the first installation notch 11, so that after the vibration isolator 20 is assembled and connected to the fixing plate 10, a portion of the connecting pipeline 200 and the vibration isolator 20 can be accommodated in the first installation notch 11. Since the vibration isolator 20 is plugged into the first installation notch 11 through the limiting groove 26, the limiting groove 2 After being plugged and connected with the first mounting notch 11, the vibration isolator 20 can be limited along the axial direction of the mounting hole 24, so that when the mounting hole 24 covers part of the connecting pipeline 200, it can restrain the connecting pipeline 200, so that when the connecting pipeline 200 is driven by the vibration of the compressor and other equipment to generate a vibration force along its axial direction, the vibration isolator 20 can limit the connecting pipeline 200 along the axial direction of the connecting pipeline 200, and can be compressed to buffer and reduce vibration when subjected to the axial vibration force generated by the connecting pipeline 200, thereby achieving axial vibration isolation for the connecting pipeline 200, and because part of the vibration isolator 20 is wrapped around the outer peripheral side of the connecting pipeline 200, there is no contact between the connecting pipeline 200 and the fixing frame, thereby achieving radial vibration isolation for the connecting pipeline 200, so as to reduce the risk of vibration noise between the connecting pipeline 200 and the fixing frame caused by the vibration of the compressor, thereby improving the user experience.

[0046] In some embodiments, along the radial direction of the mounting hole 24, the distance between the center of the mounting hole 24 and the edge of the vibration isolator 20 is not less than the diameter of the connecting pipe 200. In this way, when the connecting pipe 200 is installed in the mounting hole 24, the connecting pipe 200 and the edge of the vibration isolator 20 have a large shock-absorbing margin, so that the vibration isolator 20 can play a good radial vibration isolation effect.

[0047] According to some embodiments of the present application, the vibration isolation member 20 includes a first vibration isolation pad 21 and a second vibration isolation pad 22 connected to the first vibration isolation pad 21, and a limiting groove 26 is defined between the first vibration isolation pad 21 and the second vibration isolation pad 22; wherein, the first vibration isolation pad 21 is arranged on one side of the thickness direction of the fixed plate 10 and is fixedly connected to the fixed plate 10, and the second vibration isolation pad 22 is arranged on the other side of the thickness direction of the fixed plate 10.

[0048] In this embodiment, a first connecting hole 13 is provided at the edge of the first mounting notch 11, a second connecting hole 27 is provided at the first vibration isolation pad 21, a fixing connecting piece is provided at the connecting pipeline 200, and a third connecting hole 201 is provided on the fixing connecting piece. The connecting pipeline 200 is installed in the mounting hole 24 through the opening 25, and the third connecting hole 201 is correspondingly connected with the second connecting hole 27. Then, the first vibration isolation pad 21 is arranged on one side in the thickness direction of the fixing plate 10, and the second connecting hole 27 is correspondingly connected with the first connecting hole 13. In this way, the fastener 300 is passed through the first connecting hole 13, the second connecting hole 27 and the third connecting hole 201, so that the connecting pipeline 200 and the second vibration isolation pad 22 can be fixed on the fixing plate 10. At the same time, when the connecting pipe 200 is installed in the mounting hole 24, the first vibration isolation pad 21 covers part of the circumference of the connecting pipe 200, and the connecting pipe 200 and the vibration isolation pad are fixedly connected to the fixing plate 10 by the fastener 300, thereby isolating the radial vibration of the connecting pipe 200. At the same time, at least part of the first vibration isolation pad 21 and the second vibration isolation pad 22 are shielded by the first mounting notch 11, thereby reducing the noise pollution caused by the vibration noise propagating to the outside of the outdoor unit 1000.

[0049] See also Figure 1 and Figure 2 According to some embodiments of the present application, a transition connection portion 23 is provided between the first vibration isolation pad 21 and the second vibration isolation pad 22, and the first vibration isolation pad 21, the second vibration isolation pad 22 and the transition connection portion 23 are jointly configured with a limiting groove 26; wherein the mounting hole 24 passes through the first vibration isolation pad 21, the transition connection portion 23 and the second vibration isolation pad 22 in sequence.

[0050] In this embodiment, a transition connection portion 23 is provided between the first vibration isolation pad 21 and the second vibration isolation pad 22, and the mounting hole 24 passes through the first vibration isolation pad 21, the transition connection portion 23 and the second vibration isolation pad 22 in sequence, so that the connecting pipeline 200 is partially accommodated in the mounting hole 24, and the transition connection portion 23 can cover the circumference of part of the connecting pipeline 200. Since the transition connection portion 23 extends along the axial direction of the connecting pipeline 200, it can further play a role in radial vibration isolation of the connecting pipeline 200, thereby helping to further reduce the risk of vibration noise generated by the connecting pipeline 200 and the fixing plate 10 when the compressor vibrates.

[0051] In addition, the transition connection portion 23 is at least partially located in the first installation notch 11 , which can further reduce the outward propagation of noise and facilitate the installation of the vibration isolation member 20 .

[0052] See also Figure 1According to some embodiments of the present application, the projection of the transition connection portion 23 on the first vibration isolation pad 21 along the axial direction of the mounting hole 24 is located inside the first vibration isolation pad 21, and the projection of the transition connection portion 23 on the second vibration isolation pad 22 along the axial direction of the mounting hole 24 is located inside the second vibration isolation pad 22.

[0053] In this embodiment, the radial dimensions of the first vibration isolation pad 21 and the second vibration isolation pad 22 along the connecting pipeline 200 are greater than the dimensions of the transition connection portion 23, and an annular limiting groove 26 can be defined between the first vibration isolation pad 21 and the second vibration isolation pad 22 and the transition connection portion 23. When the vibration isolation component 20 is installed, the transition connection portion 23 can be set in the first installation notch 11 from the notch portion of the first installation notch 11, and the annular limiting groove 26 is adapted to the thickness of the fixed plate 10 along the radial direction of the connecting pipeline 200. At this time, the first vibration isolation pad 21 and the second vibration isolation pad 22 are partially clamped on both sides of the thickness direction of the fixed plate 10, so that the vibration isolation component 20 and the connecting pipeline 200 can be easily fixed by the fastener 300.

[0054] According to some embodiments of the present application, along the axial direction of the mounting hole 24 , the extension length of the transition connection portion 23 is adapted to the thickness of the fixing plate 10 .

[0055] In this embodiment, since the length of the transition connection portion 23 along the axial direction of the mounting hole 24 is adapted to the thickness of the fixed plate 10, when the transition connection portion 23 is installed in the first mounting notch 11, the first vibration isolation pad 21 can be fitted with one side of the thickness direction of the fixed plate 10, which helps to improve the installation and fixing stability of the first vibration isolation pad 21 and helps to improve the assembly efficiency of the product.

[0056] According to some embodiments of the present application, the vibration isolator 20 is provided with at least one sealing section, and the at least one sealing section is used to cover at least a portion of the first installation notch 11 .

[0057] In some embodiments, the fixing plate 10 is a flat plate, and the first vibration isolation pad 21, the transition connection portion 23, and the second vibration isolation pad 22 are all provided with a sealing section. Alternatively, any one or both of the first vibration isolation pad 21, the transition connection portion 23, and the second vibration isolation pad 22 are provided with a sealing section. The sealing section is arranged along the extension length direction of the first installation notch 11, and shields at least a portion of the first installation notch 11, so as to further reduce the effect of noise propagation to the outside of the outdoor unit 1000.

[0058] See also Figure 4 According to some embodiments of the present application, a side of the fixing plate 10 facing away from the first vibration isolation pad 21 is partially recessed to form a receiving groove 12, the first mounting notch 11 extends to the bottom wall of the receiving groove 12, and at least a portion of the second vibration isolation pad 22 is located in the receiving groove 12.

[0059] In this embodiment, specifically, the receiving groove 12 is opened on the side of the fixed plate 10 facing the casing of the outdoor unit 1000, and the receiving groove 12 is used to accommodate part of the connecting pipe 200 and the second vibration isolation pad 22, thereby reducing the internal space of the casing occupied by the connecting pipe 200 and the vibration isolation member 20, and reducing the risk of interference between them and equipment parts in the casing.

[0060] See also Figure 1 According to some embodiments of the present application, the sealing section is arranged on the second vibration isolation pad 22, including a first sealing section 221, a bent sealing section 222 and a second sealing section 223 connected in sequence, the first sealing section 221 is connected to the transition connection portion 23, the bent sealing section 222 blocks the part of the side wall of the first installation notch 11 corresponding to the receiving groove 12, and the second sealing section 223 blocks the part of the first installation notch 11 located outside the receiving groove 12.

[0061] In this embodiment, since a receiving groove 12 is provided on one side of the fixing plate 10 facing the inside of the casing, and the receiving groove 12 has a bottom wall and a side wall, the first installation notch 11 first extends from one side of the fixing plate 10 to the side wall of the receiving groove 12, and then extends to the bottom wall of the receiving groove 12. By setting the second vibration isolation pad 22 to a first sealing section 221, a bent sealing section 222 and a second sealing section 223 that are adapted to the extension trajectory of the first installation notch 11, the first installation notch 11 can be shielded, thereby reducing the noise pollution caused by the vibration noise propagating from the first installation notch 11 to the outside of the outdoor unit 1000.

[0062] See also Figure 3 and Figure 4 According to some embodiments of the present application, the opening 25 is configured to be located on a side of the vibration isolator 20 away from the first installation notch 11 when the vibration isolator 20 is installed on the fixing plate 10 .

[0063] In this embodiment, when the vibration isolation member 20 is plugged into the fixing plate 10 through the limiting groove 26, at least a portion of the transition connection portion 23 is located in the first installation notch 11. At this time, since the opening portion 25 is arranged on the side of the vibration isolation member 20 away from the first installation notch 11, it can play a limiting role on the connecting pipeline 200, so as to further reduce the risk of the connecting pipeline 200 falling off from the notch end of the first installation notch 11.

[0064] See also Figures 1 to 4 According to some embodiments of the present application, there are multiple first installation notches 11, and the multiple first installation notches 11 are arranged on the fixed plate 10 at intervals along the vertical direction; there are multiple vibration isolation members 20, and the multiple vibration isolation members 20 respectively correspond to and block the multiple first installation notches 11.

[0065] In this embodiment, by setting the number of first mounting notches 11 and vibration isolators 20 to be multiple, and the vibration isolators 20 are correspondingly arranged at the positions of multiple first mounting notches 11 to cover the multiple first mounting notches 11, it is possible to achieve the effect of isolating the multiple connecting pipes 200 and reducing the outward propagation of noise when the compressor is connected to multiple connecting pipes 200.

[0066] According to some embodiments of the present application, the vibration isolation member 20 is a rubber member or a plastic member.

[0067] In this embodiment, the vibration isolator 20 is a rubber or plastic part, which has a certain degree of flexibility, and can not only play a role in shock absorption and vibration isolation, but also enable the opening 25 to undergo elastic deformation when subjected to force, thereby facilitating the installation of the connecting pipe 200 from the opening 25 on the vibration isolator 20 into the mounting hole 24. At the same time, the rubber or plastic part is easy to process and shape, suitable for mass production, and helps to reduce the production cost of the product.

[0068] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
