Description

Technical Field

[0001] This invention relates to the field of compressors, and in particular to a compressor assembly, a compressor, and a refrigeration device. Background Technology

[0002] Household refrigerator compressors are typically reciprocating piston compressors. Their working cycle includes intake, compression, and exhaust processes. During operation, periodic airflow pulsations and periodic internal vibrations are unavoidable, resulting in significant compressor noise. Existing refrigerator compressors are equipped with exhaust mufflers, which utilize their internal volume to attenuate these periodic exhaust pulsations, thus reducing vibration and noise. Some existing compressors have exhaust mufflers cast together with the cylinder block; others have independent cylindrical stamped parts suspended from the casing by a thick metal exhaust pipe. Current exhaust muffler designs fail to effectively utilize the internal space of the compressor casing, resulting in a small internal volume and poor noise reduction. Meanwhile, the exhaust muffler, which is cast together with the cylinder block, is too close to the compressor cylinder head, which will cause strong heat transfer. Heat is transferred from the exhaust muffler to the cylinder bore, resulting in excessively high compressor suction temperature, which seriously affects the compressor's cooling capacity and performance. On the other hand, the independent cylindrical stamped exhaust muffler has a cantilever beam structure. During the operation of the compressor, the exhaust muffler vibrates strongly and is transferred to the outside of the compressor housing through the metal inner exhaust pipe, which seriously affects the compressor's vibration and noise.

In the description of this invention, the terms "first" and "second" are used only to distinguish technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0028] In this invention, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention based on the specific content of the technical solution.

[0029] See Figure 1 , Figure 2 , Figure 3 An embodiment of the present invention provides a compressor assembly, including a bracket 100, a cylinder liner 200, a cylinder head component 300, an exhaust muffler 400, and an internal exhaust pipe. The bracket 100 is used to support and install components such as the cylinder liner 200, the cylinder head component 300, the exhaust muffler 400, and the internal exhaust pipe onto the compressor core. The bracket 100 is provided with a crankshaft shaft hole 101 and a cylinder liner mounting portion 102. The cylinder liner mounting portion 102 is offset to one side of the axis of the crankshaft shaft hole 101. The cylinder liner 200 is disposed in the cylinder liner mounting portion 102. The crankshaft shaft hole 101 is used to install the crankshaft and define the rotation axis of the crankshaft. The crankshaft can further drive the piston in the cylinder liner 200 to reciprocate through the connecting rod 500 to achieve refrigerant compression.

[0030] The cylinder head assembly 300 includes an intake valve plate, a valve plate, an exhaust valve plate, and a cylinder head disposed on the outer side of the cylinder liner end face. The cylinder liner 200 and the cylinder head assembly 300 cooperate to form an exhaust passage. The exhaust passage is provided with an exhaust hole 201. The bracket 100 extends outward from the crankshaft bore 101 to form a muffler mounting part 103. The exhaust muffler 400 is disposed in the muffler mounting part 103. The exhaust muffler 400 is provided with a first interface 404 and a second interface 405. The internal exhaust pipe includes a first internal exhaust pipe 601 and a second internal exhaust pipe 602. The first internal exhaust pipe 601 is connected between the first interface 404 and the exhaust hole 201. The first internal exhaust pipe 601 is used to deliver the compressed refrigerant to the exhaust muffler 400. The second internal exhaust pipe 602 is connected to the second interface 405. The second internal exhaust pipe 602 is used to deliver the refrigerant discharged by the exhaust muffler 400 to the external exhaust pipe 700.

[0031] In the technical solution of this invention, the bracket 100 extends further from the cylinder liner mounting portion 102, cleverly extending in a direction outside the cylinder liner mounting portion 102 to form a muffler mounting portion 103, used to mount a regularly or irregularly shaped exhaust muffler 400. This fully utilizes the internal space of the compressor housing, especially the space on the opposite side of the cylinder head component 300, forming a large exhaust muffler cavity, greatly reducing exhaust pulsation and improving compressor vibration noise. Simultaneously, the two internal exhaust pipes provided in this invention create a two-stage vibration reduction and noise reduction effect, further significantly improving compressor vibration noise. This invention is simple, easy to assemble, reliably connected, low in cost, and effectively improves compressor noise and vibration.

[0032] In the technical solution of the present invention, a bracket 100 is used instead of a cylinder seat. The bracket 100 is used as a bridge to connect the cylinder head component 300, crankshaft and other moving parts, stator component, rotor component and other components into a core component, which greatly reduces the number of compressor parts and processing steps. At the same time, an independent cylinder liner 200 can be used to simplify the processing of parts and make the production arrangement more flexible.

[0033] See Figures 1-3The bracket 100 acts as a bridge, connecting the cylinder head component 300, crankshaft and other moving parts, stator components, rotor components, exhaust muffler 400, etc., to form the core components. The bracket 100 is formed by stamping and bending thin-walled material. For example, in some embodiments, the bracket 100 is formed by stamping and bending a metal plate. The cylinder liner mounting part 102 is provided with a first support arm 104, a second support arm 105, and a third support arm 106. The first support arm 104 and the second support arm 105 extend in the direction away from the compressor core. A positioning groove for installing the cylinder liner 200 is formed between the first support arm 104 and the second support arm 105. An opening is left at the top of the positioning groove to facilitate the installation of the cylinder liner 200 and to achieve positioning of the cylinder liner 200 in multiple directions. The third support arm 106 extends towards the compressor core and forms a single stator leg for connection with the core. In this embodiment, the bracket 100 is formed by stamping and bending a single piece of metal plate, which greatly reduces the number of compressor parts and processing steps, making the structure simpler, lighter, and easier to assemble. Meanwhile, this invention abandons the existing structure where the cylinder seat is connected to the stator components via multiple stator legs, and instead adopts a single stator leg bracket design (100). This simplifies the structure, significantly reduces the number of compressor parts and processing steps, greatly reduces the amount of material used in components, and significantly lowers the cost of the compressor. The invention is simple, easy to assemble, reliably connected, and low in cost.

[0034] Further, see Figures 1-3 The cylinder liner 200 has a through cylinder bore inside. One end of the cylinder liner 200 has an outer flange 202. The back side end face of the outer flange 202 has a fastening groove 203. The bottom of the fastening groove 203 is flat and has a sealing function. The exhaust passage extends to the fastening groove 203 and forms an exhaust hole 201 at the bottom of the fastening groove 203. One end of the first internal exhaust pipe 601 has a clamping head 603 that mates with the fastening groove 203. The first support arm 104 has a first support arm that bends outward. The first flange 107 and the second support arm 105 are provided with a second flange 108 that bends outward. The first flange 107 and the second flange 108 are used to abut against the outer flange 202 from the back side. The first flange 107 is connected to the cylinder head component 300 by fasteners and presses the clamping head 603 into the fastening groove 203. The front and rear end faces of the clamping head 603 form a seal under pressure, so that the first internal exhaust pipe 601 is connected to the exhaust port 201, and the high-pressure refrigerant in the exhaust channel is prevented from leaking.

[0035] The exhaust muffler 400 can be independently installed on the muffler mounting portion 103 of the bracket 100, or it can be integrated into the muffler mounting portion 103 of the bracket 100, for example, in some embodiments, see [link to relevant documentation]. Figure 2 , Figure 5The exhaust muffler 400 includes an exhaust muffler cover 401, which can be formed by stamping a thin-walled metal plate. The exhaust muffler cover 401 forms a concave silencing cavity 402. The edge of the exhaust muffler cover 401 is flush with the surface of the muffler mounting part 103, which forms the exhaust muffler base plate. The inner cavity of the exhaust muffler cover and the exhaust muffler base plate together constitute the compressor exhaust muffler 400. The exhaust muffler cover 401 can be designed as an irregular shape according to the shape of the compressor housing. The irregular shape of the exhaust muffler cover 401, combined with the flat bracket 100, can fully utilize the effective space inside the compressor housing, greatly increase the effective volume of the exhaust muffler 400, significantly reduce exhaust pulsation, and reduce compressor noise and vibration.

[0036] Further, see Figure 1 , Figure 2 The muffler mounting portion 103 is fan-shaped with the crankshaft bore 101 axis as its center, and the exhaust muffler cover 401 is arc-shaped with the crankshaft bore 101 axis as its center. The inner arc surface of the exhaust muffler cover 401 forms a space to avoid the compressor connecting rod 500. A sealing gasket extending along the edge of the exhaust muffler cover 401 is provided between the exhaust muffler cover 401 and the muffler mounting portion 103 to provide a seal. In this embodiment, the exhaust muffler cover 401 adopts an arc shape, which can make full use of the internal space of the compressor housing to form a large exhaust muffler cavity 402, greatly reducing exhaust pulsation and improving compressor vibration noise.

[0037] In some embodiments, see Figures 1-6The muffler mounting part 103 is provided with a first screw mounting hole 109 and a second screw mounting hole 110. The exhaust muffler cover 401 is provided with a first connector mounting platform 402 and a second connector mounting platform 403. The first connector mounting platform 402 and the second connector mounting platform 403 are located at both ends of the exhaust muffler cover 401, that is, at both ends of the exhaust muffler cavity 402 of the exhaust muffler 400. The first interface 404 is provided on the first connector mounting platform 402, and the second interface 405 is provided on the second connector mounting platform 403. Both the first interface 404 and the second interface 405 communicate with the muffler cavity 402 of the exhaust muffler cover 401. The compressor assembly also includes a first screw 801, a second screw 802, a first exhaust connector 901, and a second screw 802. The second exhaust connector 902 is located on the second connector mounting platform 402. The first exhaust connector 901 is provided with a third screw mounting hole 903. A first screw 801 passes through the third screw mounting hole 903, the first interface 404, and the first screw 801 mounting hole 109 to fix the first exhaust connector 901, the exhaust muffler cover 401, and the muffler mounting part 103. The second exhaust connector 902 is located on the second connector mounting platform 403. The second exhaust connector 902 is provided with a fourth screw mounting hole. A second screw 802 passes through the fourth screw mounting hole, the second interface 405, and the second screw 802 mounting hole 110 to fix the second exhaust connector 902, the exhaust muffler cover 401, and the muffler mounting part 103.

[0038] Further, see Figure 7 The first exhaust connector 901 has a first exhaust chamber 904 coaxially aligned with the third screw mounting hole 903. The third screw mounting hole 903 is used to mount the first screw 801. The first exhaust chamber 904 forms an annular air passage surrounding the first screw 801 and connecting to the first interface 404 after the first exhaust connector 901 is mounted on the first connector mounting platform 402 with the first screw 801. The first exhaust connector 901 has a first mounting base 905, and a first internal exhaust pipe 601 is connected to the first mounting base 905 and communicates with the first exhaust chamber 904. Similarly, the second exhaust connector 902 has a second exhaust chamber coaxially aligned with the fourth screw mounting hole. The fourth screw mounting hole is used to mount the second screw 802. The second exhaust chamber forms an annular air passage surrounding the second screw 802 and connecting to the second interface 405 after the second exhaust connector 902 is mounted on the second connector mounting platform 403 with the second screw 802. The second exhaust connector 902 has a second mounting base, and a second internal exhaust pipe 602 is connected to the second mounting base and communicates with the second exhaust chamber.

[0039] In some embodiments, Figure 1 , Figure 2 , Figure 6 , Figure 7The first internal exhaust pipe 601 and the second internal exhaust pipe 602 are curved hollow pipes made of plastic injection molding. The first exhaust connector 901 and the second exhaust connector 902 can also be made of plastic injection molding, preferably plastic injection molding. The end of the first internal exhaust pipe 601 is inserted into the first mounting base 905 of the first exhaust connector 901, and is welded into a solid whole using infrared laser heating and melting. In this embodiment, the first internal exhaust pipe 601 has a certain curved shape, which plays a primary role in vibration reduction and noise reduction, reducing vibration transmission and attenuating the transmission of periodic vibration of the cylinder liner 200 to the exhaust muffler 400. The second internal exhaust pipe 602 has a certain spatial curved shape, which plays a secondary role in vibration reduction and noise reduction, reducing the transmission of engine vibration to the housing. Together with the second exhaust connector 902, they form a complete exhaust channel, discharging high-pressure, high-temperature gas to the external exhaust pipe 700.

[0040] It is understood that, in the embodiments of the present invention, the exhaust muffler cover 401 can also be fixed to the muffler mounting part 103 by means of adhesive bonding, snap-fit ​​connection or other methods.
