In the present embodiment, the compressor 10 includes a main body 100 and a support 200. The plurality of supporting members 200 are disposed at intervals on the main body 100, and each supporting member 200 is connected to a side portion of the main body 100, respectively, to stably support the main body 100. Wherein each support 200 comprises a foot 2001 and a vibration isolator 2002. The legs 2001 are connected to the sides of the body 100. The vibration isolator 2002 is provided at an end of the leg 2001 remote from the main body 100. The vibration isolators 2002 serve to support the legs 2001 and the main body 100. The side portion of the main body 100 refers to a portion outside the main body 100, and is not limited to a relative position thereof, and for example, the side portion may be formed at the top of the main body 100, at the bottom of the main body 100, or between the top and the bottom of the main body 100. In the present embodiment, the supporter 200 is connected to the bottom of the body 100.

Wherein, four supporting pieces 200 are provided at intervals at the bottom of the main body 100. The legs 2001 of each support 200 are fixedly connected to the body 100 and extend outwardly from the bottom of the body 100 to form four legs for supporting the body 100. The vibration insulator 2002 is engaged with an end of the leg 2001, which is away from the main body 100, and is configured to abut against the outside to prevent the vibration generated by the main body 100 from being transmitted to the outside through the support 200. The vibration isolator 2002 may be a rubber pad, which can provide vibration isolation and improve stability of the compressor 10 in the refrigeration equipment.

In some embodiments, the number of the supporting members 200 may also be three or more. At least three supports 200 are provided at intervals at the bottom of the main body 100 so that the main body 100 can be stably installed in the refrigerating apparatus by means of the supports 200.

Wherein the middle portion of the vibration isolator 2002 may be formed with a groove. The leg 2001 is provided with a through hole at an end thereof away from the main body. The legs 2001 are engaged in the grooves of the vibration isolators 2002 through the through holes to facilitate the mounting and dismounting of the supporting member 200. The vibration isolators 2002 may be interference-filled in the through holes of the legs 2001 to improve the vibration isolating effect. Of course, the vibration isolator 2002 may be secured to the leg 2001 in other ways.

In some embodiments, a connecting structure may be disposed between some or all of the supporting members 200, for example, a connecting rod may be disposed between the two legs 2001 located on the same side, so as to improve the stability of the supporting structure.

It should be noted that the compressors provided in the following embodiments are all adjusted based on the compressor provided in this embodiment.

Referring to fig. 1, fig. 3 and fig. 4 in combination, fig. 3 is a schematic structural diagram of a compressor according to a first embodiment of the present application, and fig. 4 is a schematic partial force-bearing diagram of a main body of the compressor according to the first embodiment.

It has been found that due to the complexity of the internal structure of the compressor, the center of gravity is usually not located at the geometric center, which results in that the resultant force of the support structure of the compressor to the main body when supporting the main body is liable to deviate from the center of gravity of the main body, resulting in abnormal vibration of the main body during operation.

In the first embodiment, the compressor 11 includes a body 110, a first support 210, and a second support 310. The first support 210 is connected to a first side 1101 of the body 110. The second support 310 is connected to the second side 1102 of the body 110. The first side 1101 is closer to the center of gravity 41 of the body 110 than the second side 1102.

Wherein the number and the structure of the first support 210 and the second support 310 are substantially the same. The first side 1101 and the second side 1102 are opposite along a vertical axis 1100 of the body 110. The vertical axis 1100 of the body 110 is the axis of the body 110 intended to be perpendicular to the plane supporting the compressor 11, i.e. the vertical axis coinciding with the axis of gravity when the compressor 11 is mounted on a certain plane of the refrigeration appliance.

The resultant force 51 of the supporting forces received by the main body 110 is a resultant force of a first supporting force 511 of the first supporting member 210 to the main body 110 and a second supporting force 512 of the second supporting member 310 to the main body 110. Since the center of gravity of the compressor 11 is shifted toward the first side portion 1101, the line of action of the resultant force 51 does not coincide with the gravity axis where the center of gravity 41 is located, that is, the resultant force 51 does not pass through the center of gravity, and thus abnormal vibration, that is, eccentric vibration occurs when the main body 110 is operated.

It should be noted that the first support 210 is the support 200 connected to the first side portion 1101, that is, the support 200 located on one side relatively close to the center of gravity 41 in at least three supports 200, and the number of the first supports 210 may be one or more, for example, the first supports 210 in this embodiment are two supports 200 on the right side. The first supporting force 511 refers to a supporting force of the first supporting member 210 to the main body 110, i.e., a resultant of supporting forces of the one or more supporting members 200 located at a side relatively close to the center of gravity 41 to the main body 110, and does not refer to a supporting force of one of the supporting members 200 to the main body 110, and the second supporting force 512 is the same. The descriptions of the "first support" and "second support" in the following embodiments are the same, and are not repeated herein.

Referring to fig. 1, 5 and 6 in combination, fig. 5 is a schematic structural diagram of a compressor according to a second embodiment of the present application, and fig. 6 is a schematic partial force-bearing diagram of a main body of the compressor according to the second embodiment.

In the second embodiment, the compressor 12 includes a main body 120 and at least three supports 200. The supporting length of each supporting member 200 is set corresponding to the distance between the side of each supporting member 200 connected to the main body 120 and the center of gravity of the main body 120, so that a point on the line of action of the resultant supporting force 52 coincides with the center of gravity 42 of the main body 120, i.e. the resultant supporting force 52 passes through the center of gravity 42.

Wherein the support length is a length of a projection of the support member 200 on a reference plane perpendicular to a vertical axis 1200 of the body 120, the vertical axis 1200 being an axis of the body 120 for being perpendicular to a plane supporting the compressor 12. The resultant supporting force 52 is a resultant force of the at least three supporting pieces 200 to the body 120 when supporting the body 120.

Wherein, the length of the projection refers to the distance between one end of the projection far away from the main body 120 and the main body 120. In other words, when the compressor 12 is placed on a horizontal plane, which is a reference plane, the support length is the length of the support member 200 in the horizontal direction.

Wherein the at least three supports 200 include a first support 220 and a second support 320. The first support 220 includes a first leg 2201 and a first isolator pad 2202. The second supporter 320 includes a second leg 3201 and a second vibration isolating pad 3202. The first leg 2201 is connected to the first side portion 1201 of the main body 120. The second leg 3201 is connected to the second side 1202 of the body 120. The first side portion 1201 is closer to the center of gravity 42 of the body 120 than the second side portion 1202. The support length of the first support 220 can be adjusted by adjusting the length of the first leg 2201. The supporting length of the second supporter 320 may be adjusted by adjusting the length of the second leg 3201.

The length of the projection of the first leg 2201 on the reference plane is greater than the length of the projection of the second leg 3201 on the reference plane. That is, the length of the first leg 2201 in the direction perpendicular to the vertical axis 1200 is greater than the length of the second leg 3201 in the direction perpendicular to the vertical axis 1200. Specifically, the first leg 2201 and the second leg 3201 each extend in a direction perpendicular to the vertical axis 1200. At this time, the supporting length of the first supporting member 220 is equal to the length of the first supporting member 220, that is, the length of the first leg 2201; the supporting length of the second supporter 320 is equal to the length of the second supporter 320, i.e., equal to the length of the second leg 3201. Wherein, the length of the first leg 2201 is greater than the length of the second leg 3201.

In some embodiments, the first leg 2201 and the second leg 3201 do not extend entirely in a direction perpendicular to the vertical axis 1200, but entirely or partially form an angle with the reference plane, and the supporting lengths of the first support 220 and the second support 320 are not equal to their respective lengths, but are equal to their respective projection lengths on the reference plane.

In some embodiments, the end of first isolator pad 2202 that is distal to main body 120 is farther from main body 120 in a direction perpendicular to vertical axis 1200 than the end of first leg 2201 that is distal to main body 120. The length of the first support member 220 is not equal to the length of the first leg 2201. At this time, the supporting length of the first supporting member 220 is equal to the distance between one end of the first vibration isolating pad 2202, which is projected on the reference plane away from the main body 120, and the main body 120.

Through the above design, the acting force of the main body 120 on the first supporting member 220 is greater than the acting force of the main body 120 on the second supporting member 320, and the direction of the acting force changes, so that the resultant force of the first supporting force 521 of the first supporting member 220 on the main body 120 and the second supporting force 522 of the second supporting member 320 on the main body 120 passes through the center of gravity 42, and the resultant force of the first supporting force 521 and the second supporting force 522 is the supporting resultant force 52, that is, a point on the acting line of the supporting resultant force 52 coincides with the center of gravity 42 of the main body 120.

In the present embodiment, the included angle between the plurality of supporting members 200 on the reference plane is not limited. The compressor 12 can adjust the length of the supporting member 200 to enable a plurality of supporting members 200 with any included angle to achieve the above-mentioned effect.

It should be noted that the present embodiment is to express the different adjustment ways of the at least three supporting members 200 in the present embodiment by describing the differences between the first supporting member 220 and the second supporting member 320. In an actual product, the differently adjusted supports 200 are not limited to only the first support 220 and the second support 320, but may include a third support 200, and even a fourth, fifth, etc. plurality of supports 200. The plurality of supporters 200 are not limited to be provided at both sides of the compressor 12, but may be provided at a plurality of sides of the compressor 12. Each of the supporting members 200 can be adjusted according to the distance between the position where the supporting member is connected to the main body 120 and the center of gravity 42, and particularly, the leg 2001 and the vibration isolator 2002 of each of the supporting members 200 can be adjusted. The same is true in the following examples, which are not described in detail below.

Referring to fig. 1, 7 and 8 in combination, fig. 7 is a schematic structural diagram of a compressor according to a third embodiment of the present application, and fig. 8 is a schematic partial force-bearing diagram of a main body of the compressor according to the third embodiment.

In the third embodiment, the compressor 13 includes a main body 130 and at least three supports 200. The height of the side portion of the main body 130 connected with each support member 200 in the direction of the vertical axis 1300 of the main body 130 is set corresponding to the distance between the side portion and the gravity center 43 of the main body 130, so that when at least three support members 200 support the main body 130, a point on the action line of the resultant support force 53 on the main body 130 coincides with the gravity center 43 of the main body 130, that is, the action line of the resultant support force 53 coincides with the gravity axis of the gravity center 43.

Wherein the height position of the at least three supports 200 in the direction of the vertical axis 1300 affects the degree of inclination of the compressor 13 when placed on a horizontal plane. For example, when the thickness dimension of the left side support 200 and the right side support 200 in the direction of the vertical axis 1300 is the same, and the height of the right side support 200 in the direction of the vertical axis 1300 is higher than that of the left side support 200, the degree of rightward inclination of the compressor 13 placed on a horizontal plane increases, resulting in a change in the force and the acting direction of the compressor 13 on the left and right side supports 200.

Wherein the at least three supports 200 include a first support 230 and a second support 330. The first support 230 is connected to the first side portion 1301 of the body 130. The second support 330 is connected to the second side 1302 of the main body 130. The first side 1301 is closer to the center of gravity 43 of the body 130 than the second side 1302. The height of the first support 230 in the direction of the vertical axis 1300 is higher than that of the second support 330, so that the resultant of the first support force 531 of the first support 230 to the main body 130 and the second support force 532 of the second support 330 to the main body 130 passes through the center of gravity 43, i.e., a point on the line of action of the resultant support force 53 coincides with the center of gravity 43.

Specifically, the first support 230 includes a first leg 2301 and a first isolator 2302. The first leg 2301 is connected to the first side 1301 of the main body 130. The second support 330 includes a second leg 3301 and a second vibration isolator 3302. The second leg 3301 is attached to the second side 1302 of the body 130. The above design can be achieved by adjusting the first leg 2301 upward.

In this embodiment, the first leg 2301 and the second leg 3301 are respectively screwed with the body 130. By adjusting the tightness of the threads of the first leg 2301 and the second leg 3301, i.e., adjusting the number of turns of the threads of the first leg 2301 and the second leg 3301, the vertical adjustment, i.e., the height adjustment, of the first leg 2301 and the second leg 3301 in the direction of the vertical axis 1300 can be achieved.

In some embodiments, the first leg 2301 and the second leg 3301 can be connected to the main body 130 by other adjustable fixing connection structures, so that the movement of the two in the height direction can be achieved by fine adjustment. Alternatively, the first leg 2301 and the second leg 3301 may be fixedly connected to a predetermined position on the main body 130 by welding, and the predetermined position may be calculated in advance.

Referring to fig. 1, 9 and 10 in combination, fig. 9 is a schematic structural diagram of a compressor according to a fourth embodiment of the present application, and fig. 10 is a schematic partial force-bearing diagram of a main body of the compressor according to the fourth embodiment.

In the fourth embodiment, the compressor 14 includes a main body 140 and at least three supports 200. The angle formed by each supporting member 200 and a reference plane perpendicular to the vertical axis 1400 of the main body 140 is set to correspond to the distance between the side of the main body 140 to which the supporting members 200 are connected and the center of gravity 44 of the main body 140, respectively, so that a point on the line of action of the resultant supporting force 54 of at least three supporting members 200 to the main body 140 when supporting the main body 140 coincides with the center of gravity 44 of the main body 140, that is, the resultant supporting force 54 passes through the center of gravity 44.

Wherein the at least three supports 200 include a first support 240 and a second support 340. The first support 240 is connected to the first side 1401 of the body 140. The second support 340 is connected to the second side 1402 of the body 140. The first side 1401 is closer to the center of gravity 44 of the body 140 than the second side 1402. The first support 240 and the second support 340 are both inclined downward, i.e., one end of the two away from the body 140 is inclined in a direction away from the body 140. The inclination angle of the first support 240 is smaller than that of the second support 340, so as to increase the inclination degree of the compressor 14 towards the direction of the first support 240 when placed on the horizontal plane, so that the resultant force of the first support 541 of the first support 240 to the main body 140 and the second support 542 of the second support 340 to the main body 140 passes through the center of gravity 44, i.e. the action line of the resultant support force 54 coincides with the gravity axis of the center of gravity 44.

Wherein the first support 240 comprises a first leg 2401 and a first vibration isolator 2402. The first leg 2401 is connected to the first side 1401 of the main body 140. The second support 340 includes a second leg 3401 and a second vibration isolator 3402. The second leg 3401 is connected to the second side 1402 of the body 140. The above design can be achieved by adjusting the inclination angles of the first leg 2401 and the second leg 3401.

Specifically, the inclination angles of the first leg 2401 and the second leg 3401 may be formed directly when mounting, or may be formed by pressing down after mounting. The bottom surfaces of first and second vibration isolators 2401, 2402 may be machined to form a flat surface that can be attached to a horizontal surface, or to form a curved surface or other shaped surface, and to support other structures by their compressibility.

In the fifth embodiment, the compressor 15 includes a main body 150 and at least three supports 200. The stiffness of the vibration isolators 2002 of each support member 200 is set to correspond to the distance between the side of the main body 150 to which the legs 2001 are attached and the center of gravity 45 of the main body 150, respectively, such that a point on the line of action of the resultant supporting force 55 coincides with the center of gravity 45 of the main body 150, i.e., the resultant supporting force 55 passes through the center of gravity 45.

Wherein the at least three supports 200 include a first support 250 and a second support 350. First support 250 includes a first leg 2501 and a first isolator pad 2502. Second support 350 includes a second foot 3501 and a second vibration isolator 3502. First and second isolators 2502 and 3502 are used to support first and second legs 2501 and 3501 and main body 150. First vibration isolator 2502 and second vibration isolator 3502 are two rubber pads having different hardness, respectively.

The stiffness of the first vibration isolator 2502 is set corresponding to the distance between the side of the main body 150 connected to the first leg 2501 and the center of gravity 45, and the stiffness of the second vibration isolator 3502 is set corresponding to the distance between the side of the main body 150 connected to the second leg 3501 and the center of gravity 45, so that the line of action of the resultant supporting force 55 on the main body 150 when the main body 150 is supported by the at least three supporting members 200 coincides with the gravity axis of the center of gravity 45 of the main body 150.

The hardness of the first and second isolators 2502, 3502 is positively correlated with the stiffness coefficient thereof. It will be appreciated that when two rubber mats of only differing hardness are subjected to the same force, the rubber mat of lesser hardness is compressed by a greater amount, i.e., the softer rubber mat is more likely to deform.

Specifically, first leg 2501 is attached to first side 1501 of body 150. The second leg 3501 is connected to the second side 1502 of the body 150. The first side 1501 is closer to the center of gravity 45 of the body 150 than the second side 1502. The first vibration isolator 2502 has a hardness smaller than that of the second vibration isolator 3502 to increase the degree of inclination toward the direction in which the first support 250 is located when the compressor 15 is placed on a horizontal plane, so that the resultant force 551 of the first support 250 to the main body 150 and the second support force 552 of the second support 350 to the main body 150 passes through the center of gravity 45, i.e., a point on the line of action of the resultant support force 55 coincides with the center of gravity 45.

In some embodiments, first and second isolators 2502, 3502 may also be other isolator materials.

Referring to fig. 1, 13 and 14 in combination, fig. 13 is a schematic structural diagram of a compressor according to a sixth embodiment of the present application, and fig. 14 is a schematic partial force-bearing diagram of a main body of the compressor according to the sixth embodiment.

In the sixth embodiment, the compressor 16 includes a main body 160 and at least three supports 200. The thickness of the vibration isolators 2002 of each support member 200 is set to correspond to the distance between the side of the main body 160 to which the legs 2001 are attached and the center of gravity 46 of the main body 160, respectively, so that a point on the line of action of the resultant supporting force 56 coincides with the center of gravity 46, i.e., the resultant supporting force 56 passes through the center of gravity 46.

Wherein the at least three supports 200 include a first support 260 and a second support 360. Wherein the first support 260 includes a first leg 2601 and a first isolator 2602. Second support 360 includes a second leg 3601 and a second isolator 3602. The first and second vibration isolators 2602 and 3602 are used to support the first and second legs 2601 and 3601 and the main body 160. First and second spacers 2602 and 3602 are two rubber pads having different hardness, respectively.

In order that a point on the line of action of the resultant support force 56 of the at least three support members 200 on the main body 160 coincides with the center of gravity 46 of the main body 160 when supporting the main body 160, the thickness of the first vibration isolator 2602, i.e., the dimension of the first vibration isolator 2602 in the direction of the vertical axis 1600 of the main body 160, is set to correspond to the distance between the side of the main body 160 to which the first leg 2601 is connected and the center of gravity 46; the thickness of the second isolator 3602, i.e., the dimension of the second isolator 2602 in the direction of the vertical axis 1600 of the main body 160, is set to correspond to the distance between the side of the main body 160 to which the second leg 3601 is connected and the center of gravity 46.

It will be appreciated that when two rubber mats of different thicknesses are subjected to the same force, with their bottom surfaces lying in the same horizontal plane, the rubber mat of greater thickness will be compressed to a greater height at its top surface.

Specifically, the first leg 2601 is connected to the first side 1601 of the main body 160. The second leg 3601 is connected to the second side 1602 of the body 160. The first side 1601 is closer to the center of gravity 46 of the body 160 than the second side 1602. The thickness of the first vibration isolator 2602 is smaller than that of the second vibration isolator 3602 to increase the degree of inclination toward the direction in which the first support member 260 is located when the compressor 16 is placed on a horizontal plane, so that the resultant of the first support force 561 of the first support member 260 to the main body 160 and the second support force 562 of the second support member 360 to the main body 160 passes through the center of gravity 46, i.e., the line of action of the resultant support force 56 coincides with the gravity axis in which the center of gravity 46 is located.

Referring to fig. 1 and fig. 15 in combination, fig. 15 is a schematic perspective view of a compressor according to a seventh embodiment of the present application.

In the seventh embodiment, the compressor 17 includes a main body 170 and at least three supports 200. At least three supports 200 are spaced apart from the body 170. The main body 170 includes a housing 1701 and an eccentric motion mechanism 1702. The eccentric motion mechanism 1702 is housed within a housing 1701. The side of the body 170 is formed in the case 1701. At least three supports 200 are attached to the sides of the case 1701.

The eccentric motion mechanism 1702 performs eccentric motion during operation. In this embodiment, the compressor 17 is a reciprocating compressor, and the eccentric motion mechanism 1702 is a crank-link mechanism driven by a motor. The crank connecting rod structure driven by the motor is the main vibration source of the reciprocating compressor. The vibration generated by the reciprocating compressor is essentially a spatial vibration formed by the combination of the displacement and the rotation of the crank link mechanism in the spatial direction. In some embodiments, the compressor 17 may be a rotary compressor or the like having a mechanism that performs an eccentric motion when operating.

It has been found that the level of noise generated by the operation of a refrigeration appliance is highly dependent on the level of vibration noise of the compressor within it. Taking a refrigerator with a reciprocating compressor as an example, the vibration of the reciprocating compressor comes from reciprocating motion driven by a crank-link mechanism, and the actual motion process is reciprocating eccentric vibration. The gravity center positions of the reciprocating compressor under different rotating speeds are different, and the action line of the supporting resultant force of the conventional supporting structure cannot be always coincided with the gravity axis of the gravity center, so that eccentric vibration is generated. The eccentric vibration is transmitted to the refrigerator body from the inside, and the vibration noise of the whole machine is generated.

To solve the above technical problem, in the present embodiment, the supporting length and the supporting height of each supporting member 200 of the compressor 17 are adjusted such that the supporting length of each supporting member 200 is set to correspond to the distance between the side of the housing 1701 to which each supporting member 200 is connected and the working center of gravity of the main body 170 when the eccentric moving mechanism 1702 is in the working state, and the supporting height of each supporting member 200 is set to correspond to the distance between the side of the housing 1701 to which each supporting member 200 is connected and the working center of gravity of the main body 170 when the eccentric moving mechanism 1702 is in the working state, so that the line of action of the supporting force of at least three supporting members 200 on the main body 170 always coincides with the working center of gravity of the main body 170. Wherein the support 200 comprises feet 2001 and a vibration isolator 2002. The support height is the minimum distance between the plane of the bottom surface of the vibration isolator 2002 and the housing 1701. The center of gravity of operation is the center of gravity of the main body 160 when the eccentric motion mechanism 1702 is in the operating state.

The supporting length of the supporting member 200 can be controlled by adjusting the length and the inclination angle of the supporting leg 2001, which can be referred to the above description of the second embodiment. The supporting height of the supporting member 200 can be controlled by adjusting the height of the connecting end of the leg 2001 to the case 1701 in the direction of the vertical axis 1700 of the main body 170, the angle formed by the leg 2001 and the reference plane perpendicular to the vertical axis 1700, the stiffness of the vibration isolating pad 2002, and/or the thickness of the vibration isolating pad 2002, which can be specifically described with reference to the third to sixth embodiments.

In other words, the height of the side portion of the case 1701 to which each leg 2001 is connected in the direction of the vertical axis 1700 is set to correspond to the distance between the side portion and the working center of gravity of the body 170, respectively.

The angle that each leg 2001 forms with a reference plane perpendicular to the vertical axis 1700 is set to correspond to the distance between the side of the housing 1701 to which the leg 2001 is attached and the working center of gravity of the main body 170, respectively.

The stiffness of each vibration isolator 2002 is set to correspond to the distance between the side of the case 1701 to which each leg 2001 connected to the vibration isolator 2002 is connected and the working center of gravity of the main body 170, respectively.

The thickness of each vibration insulator 2002 is set to correspond to the distance between the side of the case 1701 to which each leg 2001 connected to the vibration insulator 2002 is connected and the operating center of gravity of the main body 170.

The length of each leg 2001 is set to correspond to the distance between the side of the body 170 to which it is attached and the working center of gravity of the body 170.

In this embodiment, the eccentric motion mechanism 1702 has a plurality of operating states. Each operating state corresponds to a different operating frequency, i.e. to a different rotational speed. When the operating state of the eccentric motion mechanism 1702 changes, the operating center of gravity of the main body 170 shifts accordingly. The number of the working states of the eccentric motion mechanism 1702 is limited, and may be 1, 2, 3, 4, 5, 6, 7, and the like, and is not limited in particular. For example, the operating frequency of the compressor 17 may range from 20 Hz to 75Hz, and the actual operating speed may range from 900 RPM to 4500RPM, and each operating state may correspond to a value within the range. Of course, the operating frequency range and the actual operating speed of the compressor of the other embodiments are not limited to the present embodiment.

The supporting legs 2001 and the vibration isolators 2002 of each supporting piece 200 are respectively adjusted when the eccentric movement mechanism 1702 is in each working state, so that when the eccentric movement mechanism 1702 is in different working states, at least three supporting pieces 200 always have a point on the action line of the supporting force of the main body 170 when supporting the main body 170 to coincide with the working gravity center of the main body 170, thereby eliminating the eccentric vibration generated by the compressor 17 when the eccentric movement mechanism 1702 is in the working state and reducing the noise generated by the refrigerating equipment.

It is understood that the state where the rotation speed is 0 can also be regarded as an operation state of the eccentric motion mechanism 1702.

Specifically, the at least three supports 200 include a first support 270 and a second support 370. The first support 270 is connected to the first side portion 1703 of the case 1701. The second support 370 is connected to the second side 1704 of the case 1701. The supporting length and the supporting height of the first supporting member 270 are respectively set corresponding to the distance between the first side portion 1703 and the working center of gravity of the main body 170, and the supporting length and the supporting height of the second supporting member 370 are respectively set corresponding to the distance between the second side portion 1704 and the working center of gravity of the main body 170, so that a point always coincides with the working center of gravity of the main body 170 on the acting line of the supporting force of the first supporting member 270 and the second supporting member 370 to the main body 170 when supporting the main body 170.

The first side portion 1703 corresponds to a side of the housing 1701 relatively close to the center of gravity of the main body 170, and the second side portion 1704 corresponds to a side of the housing 1701 relatively far from the center of gravity of the main body 170. The structure of the at least three supports 200 may be specifically adjusted according to the position of the connection to the case 1701.

In the present embodiment, the first side portion 1703 is a right side portion of the case 1701, and the second side portion 1704 is a left side portion of the case 1701, that is, the operating center of gravity of the main body 170 is closer to the right side with respect to the left side. Specifically, the case 1701 further includes a front side and a rear side, and the working center of gravity of the body 170 is closer to the front side than to the rear side. The four supports 200 are respectively provided on the right front side, the right rear side, the left front side, and the left rear side of the case 1701, and the structure thereof is also adjusted corresponding to the distance from the working center of gravity.

For example, the right front side vibration isolators 2002 has a hardness between 30-35 degrees, the right rear side vibration isolators 2002 has a hardness between 36-40 degrees, the left front side vibration isolators 2002 has a hardness between 41-45 degrees, and the left rear side vibration isolators 2002 has a hardness between 45-50 degrees. On the basis, other structural features of the four supporting pieces 200 are adjusted correspondingly, so that the action lines of the supporting force of the four supporting pieces 200 on the main body 170 can be always coincident with the gravity axis of the gravity center of the main body 170.

Of course, in other embodiments, at least three supporting members 200 may be respectively disposed at other positions, and the corresponding structural feature of each supporting member 200 may also be adjusted according to practical situations, and is not limited to this embodiment.

It will be appreciated that the above-described support structure design may also be applied to compressors that do not have an eccentric motion mechanism.

Referring to fig. 1 and 16 in combination, fig. 16 is a schematic structural diagram of a compressor according to an eighth embodiment of the present application.

In the eighth embodiment, the compressor 18 includes a main body 180 and at least three supports 200 spaced apart on the main body 180. Each support 200 includes a foot 2001 and a vibration isolator 2002, respectively.

It has been found that the vibrations generated by the compressor are transmitted to the outside through the supporting structure, causing noise in the refrigeration equipment provided with the compressor. When the support structure of the compressor has a plurality of supports, the amplitude of vibration transmitted to each support may be different. And the vibration amplitude range corresponding to the vibration isolation pad of each supporting piece is smaller than the vibration amplitude range which can be generated by the compressor. Namely, when the damping coefficients of all the vibration isolators are the same, the range of the vibration amplitude which can be isolated by the vibration isolators can not necessarily cover the range of the vibration amplitude generated by the compressor, so that the vibration isolation effect of the whole machine is not ideal.

To solve the above problem, in the present embodiment, the damping coefficient of each vibration isolator 2002 of the compressor 18 is individually designed, so that a plurality of vibration isolators 2002 can cooperate to achieve a complete vibration isolation effect.

Specifically, the compressor 18 has multiple operating frequencies. At different operating frequencies, the force and direction of action of the body 180 on each support 200 may vary, resulting in a variation in the amplitude of the vibrations transmitted to each foot 2001. The damping coefficient of each vibration isolator 2002 of the compressor 18 is set corresponding to the distance between the side of the main body 180 connected to each support leg 2001 connected to the vibration isolator 2002 and the center of gravity of the main body 180, so that the vibration amplitude range which can be blocked by each vibration isolator 2002 can cover the vibration amplitude range generated by the support leg 2001 connected to the vibration isolator 2002, thereby realizing the full-band vibration isolation effect of the whole machine.

Wherein the at least three supports 200 include a first support 280 and a second support 380. The leg 2801 of the first support 280 is connected to the first side 1801 of the body 180. The foot 3801 of the second support 380 is connected to the second side 1802 of the body 180. The first side 1801 is closer to the center of gravity of the body 180 than the second side 1802. First support 280 includes a first isolator 2802 coupled to a first leg 2801. Second support 380 includes a second isolator 3802 coupled to second leg 3801. The first and second vibration isolators 2802 and 3802 are used to support the first and second legs 2801 and 3801 and the main body 180. The damping coefficient of the first vibration isolator 2802 is greater than the damping coefficient of the second vibration isolator 3802.

Since the center of gravity of the body 180 is closer to the first support 280 than the second support 380, the amplitude of vibration transmitted to the first leg 2801 is greater than the amplitude of vibration transmitted to the second leg 3801. Through choosing the great rubber pad of damping coefficient as first vibration isolator 2802 for use, choose the less rubber pad of damping coefficient as second vibration isolator 3802 for first vibration isolator 2802 can separate the vibration of first stabilizer blade 2801, and second vibration isolator 3802 can separate the vibration of second stabilizer blade 3801 simultaneously, thereby realizes the comprehensive vibration isolation effect of complete machine.

Wherein the first side portion 1801 corresponds to a side of the body 180 relatively close to the center of gravity thereof, and the second side portion 1802 corresponds to a side of the body 180 relatively far from the center of gravity thereof. The damping coefficient of the vibration isolators 2002 of the at least three supports 200 may be specifically adjusted according to the position of the coupling to the main body 180.

In the present embodiment, the first side 1801 is a right side portion of the main body 180, and the second side 1802 is a left side portion of the main body 180, i.e., the center of gravity of the main body 180 is closer to the right side than to the left side. Specifically, the main body 180 further includes a front side and a rear side, and the center of gravity of the main body 180 is closer to the front side than to the rear side. The four supporting members 200 are respectively disposed at the right front side, right rear side, left front side and left rear side of the main body 180, and the damping coefficient of the vibration insulators 2002 thereof is also adjusted corresponding to the distance from the center of gravity of the main body 180.

For example, the damping coefficient of the right front side vibration isolator 2002 is between 0.9 and 1.0, the damping coefficient of the right rear side vibration isolator 2002 is between 0.8 and 0.9, the damping coefficient of the left front side vibration isolator 2002 is between 0.7 and 0.8, and the damping coefficient of the left rear side vibration isolator 2002 is between 0.6 and 0.7, so that the vibration amplitude range which can be blocked by the four vibration isolators 2002 can respectively cover the vibration amplitudes generated by the four corresponding support legs 2001.

Further, the compressor 18 includes a suction pipe 601 and a discharge pipe 602. The pressure on the suction side where the suction pipe 601 is provided is generally lower than the pressure on the discharge side where the discharge pipe 602 is provided, resulting in a difference in pressure between the support member 200 disposed relatively close to the discharge side and the support member 200 disposed relatively far from the discharge side, which also affects the range of vibration amplitude transmitted from the main body 180 to the support members 200 on both sides.

Therefore, the damping coefficient of each vibration isolator 2002 of the compressor 18 is also set corresponding to the distance between the position of the leg 2001 to which it is attached on the main body 180 and the discharge side.

In other words, the damping coefficient of each isolator 2002 actually corresponds to the vibration amplitude setting of the leg 2001 to which the isolator 2002 is attached. The amplitude of vibration of each leg 2001 is directly related to where it is disposed on the body 180, including but not limited to the distance between it and the center of gravity of the body 180, the distance between it and the exhaust side of the body 180, and the like.

To sum up, this application sets up the support piece in the bottom of the main part of compressor through at least three interval and supports the main part, and at least three support piece's support length and/or support height correspond its distance setting between the position of connecting in the main part and the focus of main part respectively to make at least three support piece when supporting the main part to the line of action of the resultant force of main part and the gravity axis coincidence that the focus of main part is located, thereby can avoid the eccentric vibration that leads to because the line of action of the resultant force of at least three support piece to the main part of the focus of its main part skew during compressor operation, and then reduced the noise that refrigeration plant produced during operation.

In addition, the damping coefficients of the vibration isolators of at least three supporting pieces are respectively arranged corresponding to the distance between the position of the support leg arranged on the main body and the gravity center of the main body, so that the amplitude range which can be isolated by each vibration isolator can cover the amplitude range generated by the connected support leg, the overall vibration isolation of the whole machine is realized, and the noise generated during the working of the refrigeration equipment is further reduced.
