Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] This invention provides an exhaust shroud for a compressor and a compressor that can uniformly cool the entire motor and achieve a good cooling effect.

[0031] The following is combined with Figures 1-6 The technical solution provided by this invention will be described in more detail below.

[0032] like Figures 1-6 As shown, the exhaust shroud for a compressor provided by the present invention includes a shroud body 1 and a flow guiding structure 2; wherein,

[0033] The flow guiding structure 2 is installed through the wall of the flow cover body 1. When the flow cover body 1 is installed inside the compressor, the flow guiding structure 2 can guide the gas to flow evenly through each flow hole of the motor.

[0034] The present invention provides an exhaust shroud for a compressor, comprising a shroud body 1 and a flow guiding structure 2. The flow guiding structure 2 is disposed through the wall of the shroud body 1. When the shroud body 1 is installed inside the compressor, the flow guiding structure 2 can uniformly guide the gas entering the compressor to each flow hole of the motor. Since the motor has flow holes on the outside of the middle part, the gas can flow evenly through the middle and outside of the motor under the guidance of the flow guiding structure 2, thereby cooling the entire motor and making the motor uniformly cooled, resulting in a better cooling effect.

[0035] As a preferred or optional implementation, the flow guiding structure 2 includes a first flow guiding hole 21 and a second flow guiding hole 22 that are disposed through the top wall of the flow hood body 1. The first flow guiding hole 21 is disposed at the top of the flow hood body 1 near the side wall, and the second flow guiding hole 22 is disposed in the middle region of the top wall of the flow hood body 1.

[0036] Specifically, since there are flow holes in the middle and outer sides of the motor, in order to correspond to the flow holes of the motor, a first guide hole 21 corresponding to the flow hole on the outer side of the motor and a second guide hole 22 corresponding to the flow hole in the middle of the motor are provided on the top wall of the flow cover body 1.

[0037] As a preferred or optional implementation, the number of the first guide hole 21 and the second guide hole 22 are both at least two, and they are evenly distributed along the circumference of the flow cover body 1. This allows for better correspondence with each flow hole of the motor.

[0038] As a preferred or optional embodiment, the flow cover body 1 is provided with an elastic clamping portion 11 on the outer side in the circumferential direction, and the elastic clamping portion 11 is formed by bending the edge of the flow cover body 1. Due to the tension of the elastic clamping portion 11 itself, the elastic clamping portion 11 can abut against the compressor shell, realize the connection between the flow cover body 1 and the compressor shell, and has a certain sealing effect.

[0039] The compressor provided by the application comprises a compressor body 3 and the exhaust gas flow cover for the compressor provided by any one of the technical solutions of the application.

[0040] The compressor body 3 comprises a shell 31, a motor 32 and a pump body 33, the motor 32 and the pump body 33 are both installed in the shell 31, the motor 32 comprises a stator assembly 321 and a rotor assembly 322, a first flow-through hole 323 is arranged in the gap between the stator assembly 321 and the shell 31, and a second flow-through hole 324 is arranged in the gap between the stator assembly 321 and the rotor assembly 322.

[0041] The flow guide structure 2 comprises a first flow guide hole 21 and a second flow guide hole 22 which are arranged through the top wall surface of the flow cover body 1.

[0042] The flow cover body 1 is installed between the motor 32 and the pump body 33, the first flow guide hole 21 corresponds to the position of the first flow-through hole 323, so that the gas flow flowing out of the first flow guide hole 21 can directly enter the first flow-through hole 323, and the second flow guide hole 22 corresponds to the position of the second flow-through hole 324, so that the gas flow flowing out of the second flow guide hole 22 can directly enter the second flow-through hole 324.

[0043] Specifically, the structures of the stator assembly 321, the rotor assembly 322 and the pump body 33 are the same as those of the stator and the rotor in the motor in the prior art, and will not be described here; the first flow guide hole 21 is arranged at the top of the flow cover body 1 and close to the side wall surface, and corresponds to the position of the first flow-through hole 323 arranged in the gap between the stator assembly 321 and the shell 31, and the second flow guide hole 22 is arranged in the middle region of the top wall surface of the flow cover body 1 and corresponds to the position of the second flow-through hole 324 arranged in the gap between the stator assembly 321 and the rotor assembly 322, so that the gas entering the compressor body 3 from the distributor component 35 of the compressor body 3 can be guided by the flow guide structure 2 and directly enter the first flow-through hole 323 and the second flow-through hole 324 of the motor, so as to prevent the gas flow from being disturbed and ensure that the gas flow entering the compressor body 3 uniformly flows through each first flow-through hole 323 and second flow-through hole 324 of the motor 32, so that the cooling of the motor is more uniform and the cooling effect is better.

[0044] As a preferred or optional embodiment, the distance between the second flow guide hole 22 and the axis of the flow cover body 1 is equal to the distance between the second flow-through hole 324 and the axis of the motor 32. The second flow guide hole 22 and the second flow-through hole 324 can better correspond to each other.

[0045] As a preferred or optional embodiment, the compressor body 3 further comprises a muffler 34, which is arranged between the pump body 33 and the flow cover body 1, and the muffler 34 is provided with an exhaust hole 341, which communicates the pump body 33 with the flow cover body 1.

[0046] Specifically, the structure and connection mode of the muffler 34 are the same as those of the muffler in the prior art compressor, which will not be described here. After the gas enters the pump body 33 from the distributor part 35 of the compressor body 3, it is discharged into the flow cover body 1 through the exhaust hole 341 of the muffler 34, and then discharged into the first flow hole 323 and the second flow hole 324 through the flow guide structure 2.

[0047] As a preferred or optional embodiment, the total flow area of all the first flow guide holes 21 and the second flow guide holes 22 is smaller than the flow area of the exhaust hole 341.

[0048] Specifically, when the gas enters the flow cover body 1, the total amount of inlet gas is greater than the total amount of outlet gas, so the pressure drop can be dispersed, the gas flow rate can be reduced, the sound power can be reduced to a certain extent, and the sound-absorbing effect can be achieved; in addition, the gas flowing out of the flow guide structure 2 can have a certain flow rate, which can make the outflowing gas flow more accurately to the first flow hole 323 and the second flow hole 324, and then discharged from the first flow hole 323 and the second flow hole 324 to the outside of the compressor body 3, so that the exhaust is more smooth, and the motor cooling is more rapid, and the energy efficiency is improved. At the same time, when the liquid-carrying gas meets the top wall surface of the flow cover body 1, oil droplets are condensed and drop back to the oil pool, which can block the oil carried out by the pump body 33 during the exhaust process, reduce the discharge of oil, and reduce the oil content of the gas.

[0049] As a preferred or optional embodiment, the circumferential outer surface of the flow cover body 1 is connected with the inner surface of the shell 31 in an interference fit.

[0050] Specifically, the flow cover body 1 and the shell 31 can be an integral structure, which simplifies the assembly process, or they can be connected in an interference fit, which not only connects them but also has a certain sealing effect.

[0051] As a preferred or optional embodiment, the circumferential outer side of the flow cover body 1 is provided with an elastic clamping part 11, which abuts against the inner surface of the shell 31 to connect the flow cover body 1 with the shell 31. Since the elastic clamping part 11 is bent from the outer edge of the flow cover body 1, it has a certain elasticity, and the tension generated thereby abuts against the inner surface of the shell 31, which can play a fastening role and also has a certain sealing effect.
