Description

Technical Field

[0001] The present invention belongs to the technical field of compressor manufacturing, and particularly relates to a compressor and an air conditioner. Background Art

[0002] A conventional rotary compressor mainly consists of two major parts: a compressor body and a liquid receiver. The liquid receiver is arranged on one side of the compressor body and is fixed on a liquid receiver bracket on the housing of the compressor body through a liquid receiver pressing plate. The upper cover part of the compressor body is provided with U / V / W three-phase terminal posts for connecting an independent control driving device. Since the liquid receiver, the compressor body and the control driving device are mutually independent and separated components, they occupy a large space and are not conducive to the development of miniaturization and compactness of the air-conditioning system. Summary of the Invention

[0003] Therefore, the present invention provides a compressor and an air conditioner, which can overcome the deficiency that the liquid receiver, the compressor body and the control driving device in the prior art are mutually independent and separated components, resulting in a large occupied space.

[0004] To solve the above problems, the present invention provides a compressor, including a compressor housing and a control driving device. The compressor housing has a protruding part protruding from its outer wall surface. The protruding part is integrally formed on the compressor housing. A liquid separation chamber is constructed inside the protruding part. The protruding part has an air inlet pipe communicating with the liquid separation chamber. A liquid separation pipe is arranged inside the liquid separation chamber. The liquid separation pipe communicates the liquid separation chamber with the suction port of the pump body assembly inside the compressor housing. The control driving device is connected to the outer wall of the protruding part.

[0005] In some embodiments,

[0006] The compressor further includes a compressor body. The compressor body includes a cylinder body. The protruding part is integrally formed on a part of the circumferential wall surface of the cylinder body.

[0007] In some embodiments,

[0008] Any surface of the protruding part that is not adjacent to the cylinder body has an opening. The opening has a mating surface. A cover plate capable of closing the opening is arranged on the mating surface. The control driving device is connected to the outer side wall of the cover plate.

[0009] In some embodiments,

[0010] The mating surface has an annular groove. A sealing member is arranged in the annular groove to enable the cover plate to seal the opening.

[0011] In some embodiments,

[0012] The liquid separation pipe includes a straight pipe and an outlet elbow disposed in the liquid separation cavity. One end of the straight pipe is communicated with one end of the outlet elbow, and the other end of the outlet elbow penetrates through the cylinder body and is communicated with the suction port of the pump body assembly.

[0013] In some embodiments,

[0014] One end of the protruding portion away from the outlet elbow has an inlet pipe. A filter screen support is disposed on the inner wall of the liquid separation cavity at a position between the straight pipe and the inlet pipe, and a filter screen is disposed on the filter screen support.

[0015] In some embodiments,

[0016] A heat conducting member is disposed in the liquid separation cavity, and one side of the heat conducting member is detachably connected to the outer wall of the cylinder body.

[0017] In some embodiments,

[0018] The side of the heat conducting member facing the outer wall of the cylinder body is an arc matching the outer wall of the cylinder body, and the other side is a flat structure. The cover plate and the outer wall of the cylinder body can form a clamping force on the heat conducting member.

[0019] In some embodiments,

[0020] The heat conducting member includes a base body and a plurality of spaced-apart heat conducting columns disposed on the base body. The base body cooperates with the cylinder body, and the end of the heat conducting column abuts against the cover plate and can be deformed under the pressure of the cover plate.

[0021] The present invention further provides an air conditioner, including the above-mentioned compressor.

[0022] For the compressor and the air conditioner provided by the present invention, since the compressor housing and the protruding portion of this embodiment are of an integral structure, the overall volume of the compressor is reduced, and the assembly space of the compressor system is reduced, which is beneficial to the small and compact design of the air conditioning system. Moreover, in a conventional compressor, the liquid receiver is suspended on one side of the compressor body, and the bottom of the liquid receiver is connected to the compressor body through an outlet elbow to play a role in supporting and fixing the liquid receiver, which is similar to the structure form of a cantilever beam. The constraint of the liquid receiver is relatively weak, and the structural stability caused by vibration is relatively poor. The compressor body and the protruding portion (i.e., the liquid receiver) are of an integral structure, which can avoid the vibration disadvantage brought by the structural form in which the bottom of the protruding portion of the conventional compressor is only connected to the compressor body by an outlet elbow and plays a supporting role. At the same time, since the compressor housing is connected to the control and drive device, part of the heat released by the compressor housing can heat the refrigerant in the liquid separation cavity, reducing the risk of liquid carrying in the suction of the pump body assembly in the compressor housing, and greatly improving the performance and reliability of the compressor under low-temperature or ultra-low-temperature conditions.

Detailed implementation manners

[0028] Refer to in combination Figures 1 to 3As shown in the figure, according to an embodiment of the present invention, a compressor is provided, which includes a compressor housing and a control driving device 3. The compressor housing has a protruding portion 2 protruding from its outer wall surface. The protruding portion 2 is integrally formed on the compressor housing. A liquid separation chamber 232 is formed inside the protruding portion 2. The protruding portion 2 has an intake pipe 21 communicating with the liquid separation chamber 232. A liquid separation pipe is provided inside the liquid separation chamber 232, and the liquid separation pipe communicates the liquid separation chamber 232 with the suction port of the pump body assembly 13 inside the compressor housing. The control driving device 3 is connected to the outer wall of the protruding portion 2. In this technical solution, since the compressor housing and the protruding portion 2 of this embodiment are of an integral structure, the overall volume of the compressor is effectively reduced, and the assembly space of the compressor system is greatly reduced, which is beneficial to the small and compact design of the air-conditioning system. Moreover, the liquid receiver of a conventional compressor is suspended on one side of the compressor body 1, and the bottom of the liquid receiver is connected to the compressor body 1 through an outlet elbow 25 to play a role in supporting and fixing the liquid receiver, which is similar to the structural form of a cantilever beam. The restraint of the liquid receiver is relatively weak, and the structural stability caused by vibration is relatively poor. The integrated structure design of the protruding portion 2 (i.e., the liquid receiver) and the compressor body 1 can avoid the vibration disadvantage brought by the structural form in which the bottom of the protruding portion 2 of the conventional compressor is only connected to the compressor body 1 through the outlet elbow 25 and plays a supporting role. At the same time, since the compressor housing is connected to the control driving device 3, part of the heat released by the compressor housing can heat the refrigerant in the liquid separation chamber 232, reducing the risk of liquid carry-over in the suction of the pump body assembly 13 inside the compressor housing, greatly improving the performance and reliability of the compressor under low-temperature or ultra-low-temperature conditions. At the same time, part of the heat released inside the compressor housing is dissipated to the external environment, avoiding overheating of the refrigerant medium in the liquid separation chamber 232, resulting in serious suction overheating and causing a decrease in the energy efficiency of the compressor.

[0029] In some embodiments, the compressor further includes a compressor body 1, and the compressor body 1 includes a cylinder 11. The protruding portion 2 is integrally formed on a part of the circumferential wall surface of the cylinder 11. Integrally forming the protruding portion 2 on a part of the circumferential wall surface of the cylinder 11 can increase the contact area between the protruding portion 2 and the compressor body 1, improve the heat exchange efficiency between the compressor body 1 and the protruding portion 2, heat the protruding portion 2 with the heat generated by the compressor body 1, fully vaporize the refrigerant in the protruding portion 2, and prevent the risk of liquid carry-over in the suction of the compressor body 1.

[0030] In some embodiments, any surface of the protruding portion 2 that is not adjacent to the cylinder 11 has an opening, and the opening has a mating surface. A cover plate 26 capable of closing the opening is provided on the mating surface. The control driving device 3 is connected to the outer side wall of the cover plate 26. It is convenient for the installation of various components inside the liquid separation chamber 232 and more convenient for the later maintenance and replacement of accessories.

[0031] In some embodiments, the mating surface has an annular groove 231, and a seal 27 is disposed in the annular groove 231 so that the cover plate 26 can seal the opening. Considering the improvement of the processing and assembly processes, the sealing end face is disposed on the outer end face of the mating surface, with a simplified structure, convenient processing, and easier assembly. The seal 27 is disposed inside the annular groove 231, and the seal will not break away from the annular groove 231, resulting in a better sealing effect.

[0032] In some embodiments, the liquid separation pipe includes a straight pipe 24 and an outlet elbow 25 disposed in the liquid separation chamber 232. One end of the straight pipe 24 is communicated with one end of the outlet elbow 25, and the other end of the outlet elbow 25 penetrates through the cylinder body 11 and is communicated with the suction port of the pump body assembly 13. In a conventional compressor, the outlet elbow 25 is designed outside the protrusion 2, and the heat exchange between the external environment and the inside of the outlet elbow 25 causes suction loss of the compressor body 1. Designing the outlet elbow 25 inside the protrusion 2 can make the suction component of the compressor body 1 entirely in the low-temperature and low-pressure environment of the liquid separation chamber 232, effectively avoiding the suction loss of the compressor body 1.

[0033] In some embodiments, one end of the protrusion away from the outlet elbow 25 has an inlet pipe 21, and a filter screen support 22 is disposed on the inner wall of the liquid separation chamber 232 at a position between the straight pipe 24 and the inlet pipe 21, and a filter screen 29 is disposed on the filter screen support 22. In this embodiment, a filter screen support 22 is disposed on the inner wall of the liquid separation chamber 232 at a position between the straight pipe 24 and the inlet pipe 21, and a filter screen 29 is disposed on the filter screen support 22. The refrigerant flowing out from the inlet pipe 21 is filtered by the filter screen 29.

[0034] In some embodiments, there is a heat conducting member in the liquid separation chamber 232, and one surface of the heat conducting member is detachably connected to the outer wall of the cylinder body 11. On the one hand, it improves the problem of uneven temperature in the liquid separation chamber 232 and enhances the liquid separation ability of the liquid separation chamber 232. On the other hand, it is convenient for installation and disassembly. The heat conducting member can be a heat conducting fin structure.

[0035] In some embodiments, the side of the heat conducting member facing the outer wall of the cylinder body 11 is an arc matching the outer wall of the cylinder body 11, and the other side is a flat structure. The cover plate 26 and the outer wall of the cylinder body 11 can clamp the heat conducting member. This facilitates the installation of the heat conducting member. Additionally, the heat conducting member and the cylinder body can be processed separately, reducing the processing difficulty.

[0036] In some embodiments, the heat-conducting member includes a base and a plurality of heat-conducting columns spaced apart from each other provided on the base, the base cooperates with the cylinder 11, the ends of the heat-conducting columns abut against the cover plate 26 and can be deformed under the pressure of the cover plate 26. The heat-conducting member of this embodiment includes a base and a plurality of heat-conducting columns spaced apart from each other provided on the base, the base cooperates with the cylinder 11, the cylinder 11 can better heat the base, and the plurality of heat-conducting columns spaced apart from each other on the base can more evenly heat the liquid separation chamber 232, thereby improving the liquid separation capacity of the liquid separation chamber 232. The ends of the heat-conducting columns abut against the cover plate 26 and can be deformed under the pressure of the cover plate 26, thereby achieving reliable clamping and positioning of the heat-conducting member.

[0037] In a specific embodiment, the compressor mainly includes three parts: a compressor body 1, a liquid reservoir, and a control drive device 3. Among them, the compressor body 1 includes the pump body assembly 13, the motor assembly 12, the cylinder 11, the upper cover 14, the lower cover 15 and other major components. The liquid reservoir mainly includes the air inlet pipe 21, the filter 29, the filter bracket 22, the straight pipe 24, the air outlet elbow 25 and the liquid reservoir cover (i.e., the cover 26) and the sealing ring (i.e., the sealing member 27) and other major components. The compressor body 1 and the liquid reservoir share the cylinder 11. The liquid reservoir is adjacent to the compressor body 1 and has adjacent walls. The control drive device 3 is adjacent to the liquid reservoir, and the control drive device 3 and the liquid reservoir cover are assembled and fixed to the cylinder 11 of the compressor body 1 by connecting screws 4, forming an integrated structure of the compressor body 1, the liquid reservoir, and the control drive device 3, which greatly reduces the overall volume occupied by the compressor and the control drive accessories, and is conducive to the small and compact design of the air-conditioning system. At the same time, since the liquid reservoir is adjacent to both the compressor body 1 and the control drive unit 3, the high temperature environment of the compressor body 1 and the heat emitted by the control drive unit 3 can cause the low-temperature refrigerant flowing through the liquid reservoir to further absorb heat, reducing the amount of liquid carried by the air entering the compressor pump assembly 13, thereby greatly increasing the actual air intake of the compressor under low or ultra-low temperature conditions, improving the compressor capacity while reducing the risk of liquid pressure and wear of pump body parts caused by the liquid carried by the compressor pump assembly 13. Similarly, the low-temperature refrigerant flowing through the liquid reservoir can promptly carry away the heat emitted by the control drive unit 3 and the compressor body 1, thereby having a heat dissipation effect on the control drive unit 3 and the compressor body 1.

[0038] The cylinder body 11 is an integrally formed structure, having a cylinder inner cavity and a liquid storage buffer cavity (i.e., the liquid separation cavity 232) provided on one side of the cylinder body. Among them, the cylinder inner cavity is used to assemble the pump body assembly 13 and the motor assembly 12, and cooperates with the upper cover 14 and the lower cover 15 to form a sealed cavity, jointly constituting the compressor body 1. A liquid storage filter screen 29, a filter screen support 22, a straight pipe 24, and an air outlet elbow 25 are assembled in the liquid storage buffer cavity, and together with the liquid storage cover plate, the sealing ring, and the liquid storage inlet pipe 21 installed on the side wall of the liquid storage buffer cavity, they form the liquid storage device. Further, the liquid storage buffer cavity has circumferential side walls adjacent to and non-adjacent to the wall surface of the cylinder body 11. A circumferential sealing ring groove (i.e., the annular groove 231) is provided on the end surface of the circumferential side wall. A sealing ring is installed in the groove. The liquid storage cover plate cooperates with the end surface of the circumferential side wall, and the effective sealing of the liquid storage buffer cavity is ensured through the sealing ring.

[0039] Further, threaded holes 28 are provided on the end surface of the circumferential side wall of the liquid storage buffer cavity. Screw mounting holes corresponding to the positions and quantities of the threaded holes 28 are provided on the liquid storage cover plate and the control driving device 3. The control driving device 3 cooperates with the liquid storage cover plate and is fixed to the circumferential side wall of the liquid storage buffer cavity through the connecting screws 4.

[0040] According to an embodiment of the present invention, an air conditioner is further provided, including the above-mentioned compressor.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
