Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a shock-absorbing structure of an air supply pipe of a compressor, a compressor and an air conditioner thereof. Background Art

[0002] The gas-injection reheat compressor is a new type of compressor that utilizes gas boosting and reheating technologies to improve compression efficiency and reduce energy consumption. A gas-injection valve regulates the refrigerant flow, converting liquid refrigerant into a gas-liquid mixture for enhanced cooling efficiency. Gas is drawn in through an intermediate pressure intake port, mixed with partially compressed refrigerant, and then compressed, achieving two-stage compression. This allows the compressor to deliver higher cooling efficiency, lower noise, and lower energy consumption at the same power output, making it ideal for applications requiring efficient cooling, such as large offices, supermarkets, and factories.

[0003] In order to improve the heating capacity of the air conditioner and protect and extend the service life of the compressor, an air supply pipeline is generally set in the air supply and reheat increasing compressor to supply medium-pressure gas to the middle cavity of the compressor. This can increase the exhaust volume and reduce the exhaust temperature, thereby improving the heating capacity. At the same time, it can balance the pressure and avoid liquid backflow in the compressor to protect the compressor.

[0004] However, during the use of the air supply pipeline, the air supply pipeline will vibrate due to the air supply pulsation, resulting in a large stress value of the air supply pipeline. The air supply pipeline is prone to rupture after the unit has been running continuously for a long time. At present, in order to reduce the stress value, a silencer and multiple U-bends are usually added to the air supply pipeline, and multiple counterweights are added to the piping. However, since different air conditioners have different equipment space structures or are used with different compressors, the current shock-absorbing structure on the air supply pipeline is difficult to use universally. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a shock-absorbing structure for a compressor air supply pipe, a compressor and an air conditioner thereof, so as to solve the problem that the air supply pipe may vibrate due to air supply pulsation, resulting in a large stress value in the air supply pipe, and the air supply pipe may easily break after the unit has been running continuously for a long time.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a shock-absorbing structure of a compressor air supply pipe, including a compressor body, an intake pipe and an air supply pipe. The compressor body is provided with an intake port and an air supply port. The intake pipe is connected to the intake port of the compressor body, and the air supply pipe is connected to the air supply port of the compressor body. There are several air supply pipes, and the air supply pipes are fixedly connected to the intake pipe or the compressor body.

[0007] The technical principle of the present invention is: in conventional design, the diameter of the intake pipe is basically more than twice that of the air supply pipe. Therefore, when the intake pipe is in use, the relative vibration generated by the air flow in the intake pipe is very small. At this time, since the air supply pipe is fixed to the intake pipe or the compressor body, the vibration of the compressor air supply pipe and the air outlet pipe can be effectively reduced, the stability of the air supply pipe structure is improved, and the air supply pipe is not prone to breakage.

[0008] Furthermore, it also includes:

[0009] The muffler is arranged between the air supply pipe and the air supply port of the compressor body, and the muffler is fixedly installed on the compressor body or the suction pipe.

[0010] Through the above setting, the outlet pipe of the muffler is directly connected to the air supply port of the compressor body. The muffler is fixed to the intake pipe. The muffler can directly absorb the vibration of the air supply pipe, making the air supply pipe less prone to vibration and fatigue damage.

[0011] Furthermore, the air supply pipe includes a first air supply pipe and a second air supply pipe. The first air supply pipe is installed between the muffler and the compressor body, and the first air supply pipe is in a straight pipe shape.

[0012] Through the above arrangement, the first air supply pipe can guide the airflow in a linear manner, reduce the impact of the airflow in the first air supply pipe on the inner wall of the first air supply pipe, directly reduce the vibration of the first air supply pipe, and also reduce fatigue damage to the first air supply pipe.

[0013] Furthermore, a portion of the first air supply pipe is in a curved tube shape, and a bending angle of the curved tube portion of the first air supply pipe is greater than or equal to 120° and less than 180°.

[0014] Through the above arrangement, the bending angle of the bend of the first air supply pipe is limited, which can reduce the impact between the bend of the first air supply pipe and the airflow, reduce the impact of the airflow on the first air supply pipe, and reduce the vibration of the first air supply pipe.

[0015] Furthermore, the silencer is a T-type silencer, the first air supply pipe is connected to the middle of the T-type silencer and is fixedly connected to the intake pipe, and the second air supply pipe is connected to the tail of the T-type silencer and is fixedly connected to the compressor body.

[0016] Through the above-mentioned setting, the T-type silencer can be connected with the first air supply pipe and the second air supply pipe at multiple angles, so that the first air supply pipe and the second air supply pipe are diverted into the T-type silencer for silencer treatment, and the compressor body is comprehensively supplied with air; the T-type silencer can fully silence the airflow, further reduce the overall vibration of the compressor, and the first air supply pipe and the second air supply pipe are not prone to vibration.

[0017] Furthermore, it also includes a plurality of fixed connecting parts, which are fixedly installed on the side walls of the intake pipe and the muffler.

[0018] Through the above arrangement, the fixed connection piece can allow the muffler to be more stably installed on the intake pipe as a whole, so that the installation of the muffler is also more stable and less prone to vibration.

[0019] Furthermore, the fixing point of the muffler and the intake pipe is close to one end of the intake pipe close to the intake port.

[0020] Through the above settings, the vibration of the muffler is mainly affected by the suction pipe of the compressor body. The fixed position here should be close to the suction port of the compressor so that the vibration of the muffler is consistent with the compressor body, making the overall shock resistance of the compressor better.

[0021] Furthermore, a buffer block is provided between the side wall of the muffler and the side wall of the intake pipe, and an arc-shaped groove that can fit with the side wall of the muffler or the side wall of the intake pipe is provided on the side wall of the buffer block.

[0022] Through the above arrangement, the buffer block can further buffer the muffler and the intake pipe, thereby improving the integrity between the muffler and the intake pipe and reducing the vibration of the muffler, the intake pipe and the air supply pipe.

[0023] The utility model also intends to provide a compressor, including a shock absorbing structure of an air supply pipe of the compressor.

[0024] The technical principle of the utility model is: the shock-absorbing structure of the compressor air supply pipe is adopted in the compressor, which can make the compressor have a tighter overall structure, thereby effectively reducing the vibration of the entire compressor, reducing the overall noise of the compressor, making it quieter during use, and also extending the service life of the air supply pipe in the compressor.

[0025] The utility model also intends to provide an air conditioner, comprising an air conditioner body and a compressor, wherein the compressor is installed in the air conditioner body.

[0026] The technical principle of the utility model is that after the entire air conditioner uses the compressor, the air conditioner as a whole will be quieter and more comfortable to use, which can improve customer satisfaction. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 This is a structural schematic diagram of the axial direction of the shock-absorbing structure of the compressor air supply pipe in Example 1 of the utility model.

[0028] In the above drawings: compressor body 1, air intake port 10, air supply port 11, air intake pipe 2, first air supply pipe 31, second air supply pipe 32, T-type muffler 4, clamp 5, fixed connector 6, fixing rod 61, arc-shaped clamping plate 62, buffer block 70. DETAILED DESCRIPTION

[0029] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1

[0031] This embodiment is basically as Figure 1 As shown, an embodiment of the utility model proposes a shock-absorbing structure for a compressor air supply pipe, including a compressor body 1, an intake pipe 2, two air supply pipes, a muffler, a clamp 5 and a number of fixed connectors 6. The compressor body 1 is provided with an intake port 10 and an air supply port 11 facing vertically upwards. The intake pipe 2 is connected to the intake port 10 of the compressor body 1. The air supply pipe includes a first air supply pipe 31 and a second air supply pipe 32. The first air supply pipe 31 is installed between the muffler and the compressor body 1.

[0032] Among them, such as Figure 1 As shown, most of the structure of the air supply pipe is in the shape of a straight pipe, and some parts of the air supply pipe are in the shape of a curved pipe, and the bending angle of the curved pipe is greater than or equal to 120° and less than 180°.

[0033] At the same time, the silencer is a T-shaped silencer 4, which is arranged between the air supply pipe and the air supply port 11 of the compressor body 1, and the T-shaped silencer 4 is fixedly installed on the intake pipe 2; Figure 1 As shown, the first air supply pipe 31 on the right is connected to the middle part of the T-type muffler 4 and is fixedly connected to the intake pipe 2, and the second air supply pipe 32 on the left is connected to the tail part of the T-type muffler 4 and is fixedly connected to the compressor body 1 through the clamp 5.

[0034] like Figure 1 As shown, the fixed connector 6 includes a fixed rod 61 and an arc-shaped clamping plate 62. The two ends of the arc-shaped clamping plate 62 can be detachably mounted on the fixed rod 61. The arc-shaped clamping plate 62 can be pressed against the outer walls of the intake pipe 2 and the T-shaped muffler 4 to limit the position, so that the fixed connector 6 can fix the intake pipe 2 and the T-shaped muffler 4 together.

[0035] In addition, the fixing point of the T-shaped silencer 4 and the intake pipe 2 is close to the end of the intake pipe 2 close to the intake port 10, and a buffer block 70 is provided between the side wall of the silencer and the side wall of the intake pipe 2. The side wall of the buffer block 70 is provided with an arc groove that can fit with the side wall of the silencer or the side wall of the intake pipe 2.

[0036] When the shock-absorbing structure of the compressor air supply pipe in this embodiment is in use, the first air supply pipe 31 and the second air supply pipe 32 are connected to the muffler, the outlet pipe of the muffler is directly connected to the air supply port 11 of the compressor body 1, and the muffler is fixed to the intake pipe 2. The muffler can directly absorb the vibration of the first air supply pipe 31 and the second air supply pipe 32.

[0037] At the same time, in the conventional design, the intake pipe 2 is basically more than twice the diameter of the first air supply pipe 31 or the second air supply pipe 32. Therefore, when the intake pipe 2 is in use, the relative vibration generated by the airflow in the intake pipe 2 is very small. At this time, since the first air supply pipe 31 and the second air supply pipe 32 are fixed to the intake pipe 2 or the compressor body 1, the vibration of the first air supply pipe 31, the second air supply pipe 32 and the outlet pipe on the compressor body 1 can be effectively reduced, and the structural stability of the first air supply pipe 31 and the second air supply pipe 32 is improved, so that the first air supply pipe 31 and the second air supply pipe 32 are not prone to breakage.

[0038] At the same time, since the first air supply pipe 31 has no excessive bends and the angle of the local bend is relatively large, the impact of the airflow in the first air supply pipe 31 on the inner wall of the first air supply pipe 31 can be weakened, the vibration of the first air supply pipe 31 can be directly reduced, and the fatigue damage of the first air supply pipe 31 can be reduced, and the buffer block 70 can further buffer the muffler and the intake pipe 2; at the same time, the first air supply pipe 31 and the second air supply pipe 32 are fixedly connected to the intake pipe 2 or the compressor body 1, so that the first air supply pipe 31 and the second air supply pipe 32 are integrated with the air supply pipeline and the compressor body 1, further improving the stability of the first air supply pipe 31 and the second air supply pipe 32.

[0039] Example 2

[0040] The difference between Example 2 and Example 1 is that a compressor is further disclosed, including a shock-absorbing structure of the compressor air supply pipe.

[0041] In this embodiment, the compressor adopts a shock-absorbing structure of the compressor air supply pipe, which can make the compressor a tighter overall structure, thereby effectively reducing the vibration of the entire compressor, reducing the overall noise of the compressor, making it quieter during use, and also improving the service life of the air supply pipe in the compressor.

[0042] Example 3

[0043] The difference between Example 3 and Example 2 is that an air conditioner is further disclosed, including an air conditioner body and a compressor, and the compressor is installed in the air conditioner body.

[0044] When the air conditioner in this embodiment is in use, after the entire air conditioner uses the compressor in Example 2, the air conditioner as a whole will be quieter and more comfortable to use, which can improve customer satisfaction.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
