Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes the discharge pipe 1 of the compressor 2 according to an embodiment of the present invention with reference to the drawings.

Referring to fig. 1-4, in the exhaust pipe 1 of the compressor 2 according to the embodiment of the first aspect of the present invention, the exhaust pipe 1 is adapted to be connected to the exhaust port 21 of the compressor 2, and the exhaust pipe 1 includes a first pipe segment 11 and a second pipe segment 12. The refrigerant flows out of the discharge port 21 of the compressor 2 and flows into the discharge pipe 1. The first pipe section 11 extends along the vertical direction, which is beneficial to smooth flowing of the refrigerant in the first pipe section 11, and meanwhile, the vertical extension of the first pipe section 11 is beneficial to saving the internal space of the whole machine, is convenient for arranging other parts, and is beneficial to saving the volume of the whole machine.

The second pipe section 12 is connected with the first pipe section 11, the refrigerant can flow through the second pipe section 12 and the first pipe section 11, and the second pipe section 12 is bent towards the horizontal direction to deviate from the plane of the first pipe section 11. In the exhaust pipe 1 of the present application, the second pipe segment 12 is bent towards the horizontal direction, so that the second pipe segment 12 and the first pipe segment 11 are not in the same plane, and an included angle is formed between the plane where the extending direction of the second pipe segment 12 is located and the plane where the extending direction of the first pipe segment 11 is located. For example, the second pipe section 12 may extend in a horizontal plane and the first pipe section 11 may extend in a vertical plane. When vibration of the compressor 2 itself is transmitted to the exhaust pipe 1 or when vibration of the exhaust pipe 1 is caused by pulsation of the refrigerant in the exhaust pipe 1, the vibration is transmitted in the extending direction of the exhaust pipe 1. When the vibration on the exhaust pipe 1 passes through the junction of the second pipe segment 12 and the first pipe segment 11, the transmission direction of the vibration is largely changed. For example, as vibration is transferred from the second pipe segment 12 to the first pipe segment 11, the transfer of vibration in the horizontal plane changes to a transfer in the vertical plane; alternatively, when vibration is transmitted from the first pipe section 11 to the second pipe section 12, the transmission of vibration in the vertical plane is changed to transmission in the horizontal plane. Therefore, the energy of the vibration is greatly consumed, the vibration transmitted along the extending direction of the exhaust pipe 1 is better inhibited, the vibration on the exhaust pipe 1 is reduced, the noise generated by the vibration of the exhaust pipe 1 is reduced, the pipeline stress of the exhaust pipe 1 is reduced, and the risk of pipe breakage of the exhaust pipe 1 is reduced. Meanwhile, the second pipe section 12 is bent towards the horizontal direction, so that the structural strength of the exhaust pipe 1 is improved, and the vibration on the exhaust pipe 1 can be further reduced.

When the compressor 2 is operated, the compressor 2 compresses a refrigerant and generates vibration, the vibration of the compressor 2 is transmitted to the discharge pipe 1 connected to the discharge port 21, and the vibration is transmitted in the extending direction of the discharge pipe 1. The compressed refrigerant flows from the compressor 2 into the discharge pipe 1, and the refrigerant is compressed to generate pulsation and impact the discharge pipe 1, thereby causing vibration of the discharge pipe 1, and the vibration is transmitted in the extending direction of the discharge pipe 1. When vibration is transmitted to the joint of the second pipe section 12 and the first pipe section 11, the transmission direction of the vibration is greatly changed, so that the energy of the vibration is greatly consumed, the vibration on the exhaust pipe 1 is reduced, the noise generated by the vibration of the exhaust pipe 1 is reduced, and the risk of pipe breakage of the exhaust pipe 1 is reduced.

According to the utility model discloses an exhaust pipe 1 links to each other with first pipeline section 11 through setting up second pipeline section 12, and second pipeline section 12 is buckled with the plane at skew first pipeline section 11 place towards the horizontal direction, can reduce because of the vibration of compressor 2 itself or the vibration of blast pipe 1 that the refrigerant pulsation caused to pipe-line system's impact to reduced the produced noise of 1 vibration of blast pipe, reduced the risk of 1 disconnected pipe of blast pipe.

Referring to fig. 3, according to some embodiments of the present invention, the angle between the plane in which the second pipe section 12 lies and the horizontal plane is in the range of 0-30 °. Due to the design, a small angle is formed between the plane of the second pipe section 12 and the horizontal plane, so that when vibration on the exhaust pipe 1 is transmitted to the joint of the second pipe section 12 and the first pipe section 11, the transmission direction of the vibration is greatly changed, the energy of the vibration is greatly consumed, and the vibration of the exhaust pipe 1 is effectively reduced.

Referring to fig. 1-3, according to some embodiments of the present invention, the angle between the plane of the second pipe section 12 and the plane of the first pipe section 11 ranges from 75 to 135 °. If the included angle between the plane of the second pipe section 12 and the plane of the first pipe section 11 is too small, the refrigerant flows in the joint between the second pipe section 12 and the first pipe section 11. If the included angle between the plane of the second pipe section 12 and the plane of the first pipe section 11 is too large, the change degree of the vibration transmission direction is small when the vibration passes through the joint of the second pipe section 12 and the first pipe section 11, so that the energy consumption of the vibration is small, and the vibration attenuated by the exhaust pipe 1 is small. At the same time, the space occupied by the second pipe section 12 and the first pipe section 11 is increased, which is not beneficial for arranging other parts of the compressor 2. The included angle between the plane where the second pipe section 12 is located and the plane where the first pipe section 11 is located is limited in a proper range, so that the vibration of the exhaust pipe 1 can be effectively weakened while the refrigerant flows smoothly in the exhaust pipe 1, the space occupied by the second pipe section 12 and the first pipe section 11 can be reduced, other parts can be conveniently arranged, and the whole machine volume can be saved.

Referring to fig. 1-3, according to some embodiments of the present invention, the second pipe section 12 is connected upstream of the first pipe section 11 in the flowing direction of the air flow (the upstream is relative to the flowing direction of the air flow in the exhaust pipe), and the refrigerant flows from the second pipe section 12 to the first pipe section 11 when flowing in the exhaust pipe 1, so that the refrigerant flows into the second pipe section 12 after flowing out of the compressor 2 and then flows into the first pipe section 11 from the second pipe section 12. The design enables the vibration of the compressor 2 to be transmitted to the second pipe section 12 first and then to be transmitted to the first pipe section 11 from the second pipe section 12, and the second pipe section 12 can effectively reduce the vibration, so that the vibration transmitted to the first pipe section 11 is smaller, and the risk of pipe breakage of the first pipe section 11 is reduced.

Referring to fig. 1-3, optionally, a second pipe segment 12 is attached to the upper end of the first pipe segment 11. Since the second pipe segment 12 is connected to the upstream of the first pipe segment 11, the refrigerant can flow into the first pipe segment 11 from the second pipe segment 12 by gravity, so that the refrigerant can flow smoothly.

Referring to fig. 1 and 2, alternatively, the discharge pipe 1 of the compressor 2 includes a third pipe section 13, the third pipe section 13 is U-shaped, the third pipe section 13 is connected downstream of the first pipe section 11, when vibration is transmitted on the third pipe section 13, the transmission direction of the vibration is changed, and energy of the vibration is consumed so that the vibration is reduced. This design makes it possible for the third pipe section 13 to further reduce the vibrations transmitted along the exhaust pipe 1, thereby reducing the noise generated by the vibrations of the exhaust pipe 1 and reducing the risk of breakage of the exhaust pipe 1.

Referring to fig. 1 and 2, according to some embodiments of the present invention, a muffler 111 is connected in series to the first pipe section 11, and the flow area of the muffler 111 may be larger than the flow area of the first pipe section 11. When the vibration of the exhaust pipe 1 is transmitted to the muffler 111, the sudden change of the flow area of the pipe causes the unbalance of impedance, thereby reducing the noise generated by the vibration transmitted along with the exhaust pipe 1.

Referring to fig. 1-4, according to some embodiments of the present invention, the second pipe segment 12 includes a plurality of second pipe segments 121 connected in sequence, and an included angle is formed between two adjacent second pipe segments 121. This design causes the direction of the vibration transmitted from one of the second pipe sections 121 to the adjacent second pipe section 121 to be changed when the vibration is transmitted to the second pipe section 12, and the energy of the vibration is consumed, thereby reducing the vibration. The provision of a plurality of second pipe segments 121 makes it possible to reduce the vibrations transmitted along the second pipe segments 12 a plurality of times, so that the vibrations transmitted along the exhaust pipe 1 are smaller.

In the description of the present invention, "a plurality" means two or more.

Referring to fig. 1-4, optionally, the included angle between two adjacent second sub-segments 121 ranges from 75 to 135 °. If the included angle between two adjacent second sub-pipe sections 121 is too small, the refrigerant flows in the joint between two adjacent second sub-pipe sections 121. If the included angle between two adjacent second sub-pipe sections 121 is too large, the change degree of the vibration transmission direction is small when the vibration passes through the joint between two adjacent second sub-pipe sections 121, so that the energy consumption of the vibration is small, and the vibration weakened by the second pipe section 12 is small. At the same time, the space occupied by the second pipe section 12 rises, which is detrimental to the arrangement of the other components of the compressor 2. Through injecing the contained angle between two adjacent second sub-pipe sections 121 in suitable range, when guaranteeing that the refrigerant flows smoothly in second pipe section 12, guarantee second pipe section 12 and effectively weaken the vibration to can reduce the space that second pipe section 12 occupy, be convenient for set up other spare parts, be favorable to saving the complete machine volume.

Referring to fig. 1-4, further, the included angle between two adjacent second sub-segments 121 ranges from 90 ° to 135 °. Because the plurality of second sub-pipe sections 121 are bent towards the horizontal plane, the direction of the refrigerant is frequently changed when the refrigerant flows in the plurality of second sub-pipe sections 121, and if the included angle between two adjacent second sub-pipe sections 121 is too small, the refrigerant does not smoothly flow at the connection position between two adjacent second sub-pipe sections 121. If the included angle between two adjacent second sub-pipe sections 121 is too large, the change degree of the vibration transmission direction is small when the vibration passes through the joint between two adjacent second sub-pipe sections 121, so that the energy consumption of the vibration is small, and the vibration weakened by the second pipe section 12 is small. At the same time, the space occupied by the second pipe section 12 rises, which is detrimental to the arrangement of the other components of the compressor 2. Through injecing the contained angle between two adjacent second sub-pipe sections 121 in suitable range, when guaranteeing that the refrigerant flows smoothly in second pipe section 12, guarantee second pipe section 12 and effectively weaken the vibration to can reduce the space that second pipe section 12 occupy, be convenient for set up other spare parts, be favorable to saving the complete machine volume.

Referring to fig. 1-4, according to some alternative embodiments of the present invention, the number of second sub-sections 121 is at least three. This design may allow the vibration to be transmitted along the second pipe section 12 in a plurality of times with the transmission direction of the vibration being changed and the vibration energy being dissipated a plurality of times, thereby ensuring that the plurality of second sub-sections 121 reduce the vibration transmitted along the second pipe section 12 a plurality of times, thereby allowing the vibration transmitted along the second pipe section 12 to be greatly reduced. For example, there are three second sub-segments 121; alternatively, the second sub-section 121 is more than three.
