Description

Technical Field

[0001] This application relates to the field of gas compression equipment, specifically to a compressor. Background Technology

[0002] In related technologies, a compressor is a fluid machine that elevates low-pressure gas to high-pressure gas and is an important component of a refrigeration system. The compressor primarily elevates low-pressure gas by drawing it from a low-pressure chamber into a compression chamber and discharging the compressed high-pressure gas from the compression chamber into a high-pressure chamber. However, when the intake velocity of the compression chamber is high, it generates significant noise, thus causing noise pollution. Summary of the Invention

[0003] This application provides a compressor to solve the problem of noise pollution generated during compressor operation.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a compressor, including a housing, a scroll stationary disk, and a scroll moving disk. The scroll stationary disk and the scroll moving disk are respectively disposed in the housing, and the scroll stationary disk and the scroll moving disk are connected in cooperation. The scroll stationary disk and the scroll moving disk enclose a compression chamber. The scroll stationary disk includes an air intake guide channel.

[0006] The housing includes an air intake pipe, and the air intake guide channel includes a main air intake, an auxiliary air intake, and an air outlet that are interconnected. The vortex stationary disk includes an air intake cover, and the end face of the air intake cover facing the vortex moving disk is an open end face. The main air intake is located on the open end face, and the auxiliary air intake is opened on other surfaces of the air intake cover except for the open end face. The air outlet is connected to the air intake of the compression chamber, and the main air intake and the auxiliary air intake are respectively connected to the air intake pipe.

[0007] In this embodiment, the air intake guide channel includes a main air intake and an auxiliary air intake, and the air outlet of the air intake guide channel is connected to the air intake of the compression chamber. The main air intake and the auxiliary air intake are respectively connected to the air intake pipe. In this way, the compression chamber can draw air from the air intake pipe through the main air intake and the auxiliary air intake. Since the auxiliary air intake can assist in air intake, and the air intake volume of the compression chamber is relatively fixed, by increasing the auxiliary air intake, the intake speed of the main air intake can be reduced, thereby reducing the noise during the operation of the compressor.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Please see Figure 1-7 , Figure 1-7 This application provides a compressor comprising a housing 100, a scroll stationary disk 200, and a scroll moving disk 300. The scroll stationary disk 200 and the scroll moving disk 300 are respectively disposed within the housing 100, and the scroll stationary disk 200 and the scroll moving disk 300 are connected in cooperation. The scroll stationary disk 200 and the scroll moving disk 300 enclose a compression chamber 101. The scroll stationary disk 200 includes an air intake guide channel 104.

[0018] The housing 100 includes an air intake pipe 105, and the air intake guide channel 104 includes a main air intake 1041, an auxiliary air intake 1043, and an air outlet 1042 that are interconnected. The vortex stationary disk 200 includes an air intake cover 201. The end face of the air intake cover 201 facing the vortex moving disk 300 is an open end face. The main air intake 1041 is located on the open end face. The auxiliary air intake 1043 is opened on other surfaces of the air intake cover 201 except for the open end face. The air outlet 1042 is connected to the air intake of the compression chamber 101. The main air intake 1041 and the auxiliary air intake 1043 are respectively connected to the air intake pipe 105.

[0019] The aforementioned air intake cover 201 can serve as the outer wall of the vortex stationary disk 200. The vortex stationary disk 200 can also include a stationary vortex tooth 202, which can be housed within the air intake cover 201, and the air intake cover 201 can be fixedly connected to the stationary vortex tooth 202.

[0020] The aforementioned vortex moving disk 300 can rotate relative to the vortex stationary disk 200. Specifically, the vortex moving disk 300 can reciprocate within a certain angle range relative to the vortex stationary disk 200 to achieve gas compression.

[0021] The aforementioned compressor can be a scroll compressor, specifically used as a compressor in an air conditioning heat pump system. The principle of gas compression in this compressor is the same as that of various compressors in air conditioning heat pump systems in related technologies. Accordingly, in the embodiments of this application, the gas compression structure of the compressor can be the same as the internal gas compression structure of various compressors in air conditioning heat pump systems in related technologies. For example, in some embodiments of this application, the compressor may further include a crankshaft 600, a rotary drive assembly 500, and an oil sump for storing lubricating oil at the bottom of the housing 100. The housing 100 also includes a first cavity 102, a second cavity 103, and an exhaust pipe. The first cavity 102 can serve as the low-pressure cavity of the compressor, the second cavity 103 can serve as the high-pressure cavity of the compressor, the intake pipe 105 can communicate with the first cavity 102 to provide a low-pressure medium to the compression cavity 101, and the exhaust pipe can communicate with the second cavity 103 to discharge the high-pressure medium. The first end of the crankshaft 600 can extend into the oil sump. A bearing housing can be provided at the end of the scroll rotating disk 300 facing away from the scroll stationary disk 200. A journal bearing can be installed in the bearing housing. The second end of the crankshaft 600 can be connected to the journal bearing. The rotary drive assembly 500 can be installed inside the housing 100, and the power output end of the rotary drive assembly 500 can be connected to the crankshaft 600 to drive the crankshaft 600 to rotate. While the crankshaft 600 rotates, it can drive the scroll rotating disk 300 to rotate synchronously, thereby realizing the relative rotation between the scroll rotating disk 300 and the scroll stationary disk 200, thus realizing the gas compression function of the compressor. The rotary drive assembly 500 can be any drive assembly capable of outputting rotary motion, such as a conventional motor or an electromagnetic rotary motor.

[0022] It is understood that the main air inlet 1041, the auxiliary air inlet 1043, and the air inlet pipe 105 are respectively connected to the first cavity 102, and the main air inlet 1041 and the auxiliary air inlet 1043 can be connected to the air inlet pipe 105 through the first cavity 102. Thus, during the operation of the compressor, the low-pressure gas entering the compressor from the air inlet pipe 105 can flow along... Figure 1 The two arrows indicate the directions of the air intake guide channel 104, and then the air enters the compression chamber 101 from the outlet 1042 of the air intake guide channel 104, so as to realize the air intake process of the compression chamber 101.

[0023] The main air inlet 1041 can be an air inlet formed by a portion of the opening area in the opening end face. The auxiliary air inlet 1043 can be an air inlet formed by a through hole opened on the surface of the air inlet cover 201.

[0024] In this embodiment, by making the air intake guide channel 104 include a main air intake 1041 and an auxiliary air intake 1043, and by making the air outlet 1042 of the air intake guide channel 104 connected to the air intake of the compression chamber 101, and by making the main air intake 1041 and the auxiliary air intake 1043 connected to the air intake pipe 105 respectively, the compression chamber 101 can draw air from the air intake pipe 105 through the main air intake 1041 and the auxiliary air intake 1043. Since the auxiliary air intake 1043 can assist in air intake, and the air intake volume of the compression chamber 101 is relatively fixed, by increasing the auxiliary air intake 1043, the intake speed of the main air intake 1041 can be reduced, thereby reducing the noise during the operation of the compressor.

[0025] Optionally, please see Figure 3 In some embodiments of this application, the auxiliary air intake 1043 is provided on the side wall of the air intake cover 201.

[0026] In this embodiment, by opening the auxiliary air inlet 1043 on the side wall of the air inlet cover 201, air can be simultaneously introduced from the bottom and side surfaces of the vortex stationary disk 200.

[0027] Optionally, the axis of the main air intake 1041 intersects the axis of the auxiliary air intake 1043.

[0028] In this embodiment, since the axis of the main air inlet 1041 intersects the axis of the auxiliary air inlet 1043, the gas entering from the main air inlet 1041 and the gas entering from the auxiliary air inlet 1043 can converge at the intersection of their axes, and the converged gas can flow into the compression chamber 101 through the air outlet 1042.

[0029] Optionally, the side wall of the air inlet cover 201 is provided with a heat insulation plate 2013 protruding towards the inner side wall of the housing 100, and the heat insulation plate 2013 is located on the side of the auxiliary air inlet 1043 away from the opening end face.

[0030] The heat insulation plate 2013 can be an independent component connected to the air intake cover 201. For example, the connection between the heat insulation plate 2013 and the air intake cover 201 can be achieved by welding or fasteners. The heat insulation plate 2013 can be made of cast material. Alternatively, the heat insulation plate 2013 can be integrally formed with the air intake cover 201.

[0031] Please see Figure 1 and Figure 3The heat insulation plate 2013 can be located between the auxiliary air inlet 1043 and the compressor's muffler cover 400. The muffler cover 400 can separate the internal space of the housing 100 to form the first cavity 102 and the second cavity 103. Since the second cavity 103 is a high-pressure cavity, and the muffler cover 400 serves as the cavity wall of the high-pressure cavity, the temperature of the muffler cover 400 is relatively high during compressor operation. The heat insulation plate 2013 can, to a certain extent, separate the low-pressure gas entering the auxiliary air inlet 1043 from the muffler cover 400, thereby reducing the possibility that the low-pressure gas entering the housing 100 from the auxiliary air inlet 1043 will come into contact with the muffler cover 400 before entering the auxiliary air inlet 1043. This can further reduce the risk of the low-pressure gas entering the housing 100 from the auxiliary air inlet 1043 being heated by contact with the muffler cover 400 before entering the auxiliary air inlet 1043.

[0032] In this embodiment, by providing a heat insulation plate 2013 on the side of the auxiliary air inlet 1043 away from the opening end face, the risk of low-pressure gas entering the housing 100 from the auxiliary air inlet 1043 being heated by contact with the muffler cover 400 before entering the auxiliary air inlet 1043 can be reduced. This reduces the problem of overheating of low-pressure gas entering the housing 100 from the auxiliary air inlet 1043, thereby achieving a higher Coefficient of Performance (COP).

[0033] Optionally, the air intake cover 201 includes an air intake cover body 2011 and a flange plate 2012, the flange plate 2012 being located on the opening end face, and the auxiliary air intake port 1043 being opened on the air intake cover body 2011 or the flange plate 2012.

[0034] Please see Figure 4 In some embodiments of this application, the auxiliary air intake 1043 is formed on the air intake cover body 2011. Please refer to... Figure 5 In some other embodiments of this application, the auxiliary air inlet 1043 is provided on the side wall of the flange plate 2012.

[0035] In this embodiment, by opening the auxiliary air inlet 1043 on the air inlet cover body 2011 or the flange plate 2012, air can be introduced from the side wall of the housing 100.

[0036] Optionally, the air intake cover 201 includes a closed end face opposite to the open end face, the auxiliary air intake 1043 is opened on the closed end face, and the auxiliary air intake 1043 is opposite to the main air intake 1041.

[0037] Please see Figure 6In some embodiments of this application, the auxiliary air inlet 1043 is located on the closed end face of the housing 100.

[0038] In this embodiment, by positioning the auxiliary air inlet 1043 opposite to the main air inlet 1041, air can be drawn in from both the bottom and top of the housing 100 simultaneously. Furthermore, since the low-pressure gas entering from the auxiliary air inlet 1043 can slow down the intake speed of the main air inlet 1041 to some extent, it helps to further reduce the noise during the operation of the compressor.

[0039] Optionally, the air intake guide channel 104 includes at least two auxiliary air intakes 1043, which are arranged at intervals around the axis of the vortex stationary disk 200.

[0040] Please see Figure 6 Since the space available for opening the auxiliary air inlet 1043 on the closed end face of the housing 100 is reduced, two or more small auxiliary air inlets 1043 can be opened on the closed end face to increase the total air intake area of ​​the auxiliary air inlets 1043.

[0041] Accordingly, please see Figure 5 Since the sidewall thickness of the flange plate 2012 is relatively small, it is not suitable to open a large auxiliary air inlet 1043. Therefore, two or more small auxiliary air inlets 1043 can be opened on the sidewall of the flange plate 2012 to increase the total air intake area of ​​the auxiliary air inlets 1043.

[0042] In this embodiment, by including at least two auxiliary air inlets 1043 in the air intake guide channel 104, and the at least two auxiliary air inlets 1043 being arranged at intervals around the axis of the vortex stationary disk 200, it is beneficial to increase the total air intake area of ​​the auxiliary air inlets 1043.

[0043] Optionally, the vortex stationary disk 200 includes stationary vortex teeth 202 located within the air intake cover 201. The stationary vortex teeth 202 and the air intake cover 201 enclose a vortex groove 203. The air intake guide channel 104 includes an arc-shaped groove 1044 extending outward from the outermost end of the vortex groove 203. The air outlet 1042 is connected to the main air intake 1041 through the arc-shaped groove 1044. The depth of the arc-shaped groove 1044 gradually increases from the main air intake 1041 to the air outlet 1042.

[0044] Please see Figure 7 Since the depth of the main air intake 1041 is less than the depth of the arc-shaped groove 1044, in related technologies, Figure 7The connection between the main air intake 1041 and the arc-shaped groove 1044 usually requires a right-angle step for transition. However, using a right-angle step for transition can easily lead to vortex problems at the transition point.

[0045] Based on this, in this embodiment of the application, by making the depth of the arc-shaped groove 1044 gradually increase in the direction from the main air inlet 1041 to the air outlet 1042, that is, the arc-shaped groove 1044 is a slope, that is, the main air inlet 1041 and the arc-shaped groove 1044 are transitioned by a slope, so as to eliminate the right-angle step at the connection between the main air inlet 1041 and the arc-shaped groove 1044 in the related art. In this way, the vortex in the arc-shaped groove 1044 is reduced.

[0046] It is understood that the vortex-driven disk 300 may include moving vortex teeth corresponding to the stationary vortex teeth 202. The mating connection between the stationary vortex disk 200 and the vortex-driven disk 300 can mean that the stationary vortex teeth 202 of the stationary vortex disk 200 and the moving vortex teeth of the vortex-driven disk 300 mesh with each other to enclose and form a compression cavity 101. The projection of the stationary vortex teeth 202 onto the closed end face of the stationary vortex disk 200 can be an involute circle. Correspondingly, the projection of the moving vortex teeth onto the closed end face of the stationary vortex disk 200 can also be an involute circle.

[0047] Optionally, the opening end face of the main air inlet 1041 is larger than the opening end face of the auxiliary air inlet 1043.

[0048] In this embodiment, since the opening end face of the main air inlet 1041 is larger than the opening end face of the auxiliary air inlet 1043, it can be ensured that the low-pressure gas in the first cavity 102 mainly enters through the main air inlet 1041, and only a small amount of gas enters through the auxiliary air inlet 1043. This ensures that the compression cavity 101 can enter normally. Furthermore, since the auxiliary air inlet 1043 is closer to the muffler cover 400, the temperature of the gas entering through the auxiliary air inlet 1043 is higher than the temperature of the gas entering through the main air inlet 1041. This also avoids the problem of excessively high intake temperature of the compression cavity 101 due to an excessively high proportion of gas entering through the auxiliary air inlet 1043.

[0049] Optionally, the compressor further includes a muffler cover 400 and an exhaust pipe. The muffler cover 400 is located on the side of the scroll stationary disk 200 opposite to the scroll moving disk 300, and the muffler cover 400 is sealed to the inner wall of the housing 100 to divide the internal space of the housing 100 into a first cavity 102 and a second cavity 103. The muffler cover 400 has an opening for communicating with the compression cavity 101.

[0050] The stationary vortex disk 200 and the moving vortex disk 300 are respectively located in the first cavity 102, the intake pipe 105 is connected to the first cavity 102, and the exhaust pipe is connected to the second cavity 103.

[0051] The muffler cover 400 may be a muffler cover 400 commonly used in compressors in related technologies.

[0052] In this embodiment, by providing a silencer cover 400 on the side of the scroll stationary disk 200 opposite to the scroll moving disk 300, the silencer cover 400 can further silence the noise generated during the operation of the compressor, thereby helping to further reduce the noise during the operation of the compressor.

[0053] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
