[0078] The following is a detailed description of the adjustment method for the position of the center of gravity 52 of the stator part. The position of the center of gravity 52 of the stator part can be adjusted by adjusting the weight distribution of at least some parts in the stator part 12;

[0079] By adjusting the shape and / or size and / or material of at least some of the parts in the stator part 12, the weight distribution of at least some of the parts in the stator part 12 can be adjusted; preferably, the size of at least some of the parts in the stator part 12 along the axis of the stator part 12, that is, the thickness of the parts, is adjusted; so that the overall center of gravity 51 of the compressor body and the liquid distributor falls on the C1 circular surface in the top view projection of the compressor, so that the compressor and the air conditioner are stably matched through the support mechanism 3, and the noise of the air conditioner is reduced;

[0080] Among them, at least some parts of the stator part 12 include an upper flange 121 , a lower flange 122 and a cylinder 123 .

[0081] Specifically, the weight of at least some parts in the stator part 12 is configured as follows: the closer at least some parts are to the liquid separator 2, the smaller the weight is, and the farther at least some parts are from the liquid separator 2, the larger the weight is; the center of gravity 52 of the stator part is moved away from the liquid separator 2, and the center of gravity 51 of the compressor body and the liquid separator as a whole is moved close to the center of gravity 54 of the supporting mechanism.

[0084] The support mechanism 3 includes multiple legs, and the position of the center of gravity 54 of the support mechanism is related to the position of the overall center of gravity of the multiple legs; the following further explains that the support mechanism 3 includes multiple legs, and the multiple legs are arranged at intervals along the circumference of the casing 11; the position of the center of gravity 54 of the support mechanism is determined by the position of the overall center of gravity of the multiple legs; the position of the center of gravity 54 of the support mechanism can be adjusted by adjusting the position of the overall center of gravity of the multiple legs; preferably, the support mechanism 3 includes three legs.

[0085] The following is a specific description of the method for adjusting the position of the center of gravity 54 of the support mechanism. By adjusting the shape and / or size and / or support position of any one or more of the multiple legs, the position of the overall center of gravity of the multiple legs can be adjusted; wherein the size of the leg at least includes the radial size of the leg along the casing 11, and the size of the leg also includes the circumferential and axial sizes of the leg along the casing 11; the position of the leg includes the circumferential and / or axial support position of the leg along the casing 11; the center of gravity 54 of the support mechanism falls on the C2 circular surface in the top view projection of the compressor, so that the compressor and the air conditioner are stably matched through the support mechanism 3, thereby reducing the overall noise of the air conditioner.

[0086] The position of the support mechanism center of gravity 54 can be adjusted by any of the following three methods;

[0087] ① Multiple legs are arranged at intervals along the circumference of the casing 11, and the supporting position of each leg is on the same circle; by adjusting the supporting position of any one or more of the multiple legs along the circumference of the casing 11, the position of the overall center of gravity of the multiple legs can be adjusted; the overlap between the circular surface where the center of gravity 51 of the compressor body and the dispenser falls on the top view projection of the compressor and the circular surface where the center of gravity 54 of the support mechanism falls on is increased, thereby improving the stability of the compressor during operation;

[0088] Specifically, Figure 3a and Figure 3b As shown, taking the supporting mechanism 3 including three legs as an example, the three legs are respectively the first leg 31, the second leg 32 and the third leg 33; at the beginning, the connecting line of the supporting position of the first leg 31, the supporting position of the second leg 32 and the supporting position of the third leg 33 forms an equilateral triangle; the supporting position of the first leg 31 remains unchanged, and the supporting position of the second leg 32 and the supporting position of the third leg 33 are adjusted so that the supporting position of the second leg 32 and the supporting position of the third leg 33 are close to each other, and then the connecting line of the supporting position of the first leg 31, the supporting position of the second leg 32 and the supporting position of the third leg 33 forms an isosceles triangle, and the position of the overall center of gravity of the three legs moves toward the base of the isosceles triangle; wherein the supporting position of the first leg 31 is the vertex of the isosceles triangle, the connecting line of the supporting position of the second leg 32 and the supporting position of the third leg 33 is the base of the isosceles triangle, and the vertex angle of the isosceles triangle is less than 60°;

[0089] The axis of the dispenser 2 is set on the median plane 55 of the isosceles triangle. Then, in the top view projection of the compressor, the landing point of the support position of the first leg 31, the landing point of the center of gravity 54 of the support mechanism and the landing point of the center of gravity 53 of the dispenser are located on the same straight line; wherein, the median plane 55 is a plane passing through the median line of the isosceles triangle and the axis of the compressor body 1, and the median line passes through the vertex of the isosceles triangle.

[0090] ② Multiple legs are arranged at intervals along the circumference of the casing 11, and the supporting position of each leg is on the same circle; by adjusting the radial dimensions of any one or more of the multiple legs along the casing 11, the position of the overall center of gravity of the multiple legs can be adjusted; the overlap between the circular surface where the center of gravity 51 of the compressor body and the dispenser falls on the top view projection of the compressor and the circular surface where the center of gravity 54 of the support mechanism falls on is increased, thereby improving the stability of the compressor during operation;

[0091] Specifically, Figure 3a and Figure 3cAs shown, taking the supporting mechanism 3 including three legs as an example, the three legs are respectively a first leg 31, a second leg 32 and a third leg 33; at the beginning, the connecting line of the supporting position of the first leg 31, the supporting position of the second leg 32 and the supporting position of the third leg 33 forms an equilateral triangle; keeping the sizes of the second leg 32 and the third leg 33 unchanged, adjusting the size of the first leg 31, so that the radial size of the first leg 31 along the housing 11 increases by s1, the position of the overall center of gravity of the three legs moves toward the supporting position of the first leg 31; wherein the supporting position of the first leg 31 is the vertex of the equilateral triangle, and the connecting line of the supporting position of the second leg 32 and the supporting position of the third leg 33 is the base of the equilateral triangle;

[0092] The liquid distributor 2 is arranged close to the first leg 31, and the axis of the liquid distributor 2 is on the median plane 55 of the equilateral triangle. Then, in the top view projection of the compressor, the landing point of the support position of the first leg 31, the landing point of the center of gravity 54 of the support mechanism and the landing point of the center of gravity 53 of the liquid distributor are located on the same straight line; wherein, the median plane 55 is a plane passing through the median line of the equilateral triangle and the axis of the compressor body 1, and the median line passes through the vertex of the equilateral triangle.

[0093] ③ Multiple legs are arranged at intervals along the circumference of the casing 11, and the supporting position of each leg is not on the same circle; by adjusting the supporting position of any one or more of the multiple legs along the axial direction of the casing 11, the position of the overall center of gravity of the multiple legs can be adjusted; the overlap between the circular surface where the center of gravity 51 of the compressor body and the dispenser falls on the top view projection of the compressor and the circular surface where the center of gravity 54 of the support mechanism falls on is increased, thereby improving the stability of the compressor during operation;

[0094] Specifically, Figure 4a and Figure 4b As shown, taking the supporting mechanism 3 including three legs as an example, the three legs are respectively a first leg 31, a second leg 32 and a third leg 33, the first leg 31 is located at the rear end, the second leg 32 is located at the left end, and the third leg 33 is located at the right end; the supporting positions of the first leg 31 and the second leg 32 are kept unchanged, and the third leg 33 is moved upward along the axial direction of the housing 11 by a distance s2, then the position of the overall center of gravity of the three legs moves upward; or, the supporting positions of the three legs are all moved upward along the axial direction of the housing 11, then the position of the overall center of gravity of the three legs moves upward.

[0095] In addition, in the prior art, due to the oil return hole and the turbulent air flow in the liquid distributor 2, the liquid distributor 2 may experience irregular vibration, which is manifested as radial and axial vibration of the liquid distributor 2; for example, the liquid distributor 2 experiences radial vibration in the b direction;

[0096] According to the radial vibration law of the liquid distributor 2, the position of the overall center of gravity 51 of the compressor body and the liquid distributor and the position of the center of gravity 54 of the supporting mechanism can be adjusted; the position of the overall center of gravity 51 of the compressor body and the liquid distributor and the position of the center of gravity 54 of the supporting mechanism are made to match the radial vibration law of the liquid distributor 2 to weaken the radial vibration of the liquid distributor 2, reduce the noise during the operation of the compressor, and ensure the balanced and stable operation of the compressor.

[0097] Example 2

[0098] like Figure 5 As shown, different from Example 1, on the front view projection of the compressor, the vertical distance between the landing point of the center of gravity 51 of the compressor body and the liquid distributor and the landing point of the center of gravity 54 of the support mechanism is h, and h satisfies: 0≤h≤r2; wherein r2 is the radius of the circular surface of the landing point of the center of gravity 54 of the support mechanism on the top view projection of the compressor, and the circular surface of the landing point of the center of gravity 54 of the support mechanism takes the axis of the support mechanism 3 as the center;

[0099] Reduce the distance between the center of gravity 51 of the compressor body and the liquid distributor and the center of gravity 54 of the support mechanism in the vertical direction, reduce the vibration amplitude of the compressor in its own axial direction, reduce the noise during the operation of the compressor, and improve the stability of the compressor during operation;

[0100] When the vertical distance between the overall center of gravity 51 of the compressor body and the liquid dispenser and the center of gravity 54 of the supporting mechanism is 0, the offset between the overall center of gravity 51 of the compressor body and the liquid dispenser and the center of gravity 54 of the supporting mechanism disappears, and the compressor can run very smoothly; experimental research has found that: when the vertical distance h between the overall center of gravity 51 of the compressor body and the liquid dispenser and the center of gravity 54 of the supporting mechanism satisfies: h / (2*r2)≤0.5, the instability of the compressor due to the offset of the center of gravity is small, which further improves the stability of the compressor operation, thereby reducing the noise of the compressor and the noise of its air conditioner.
