In addition, there is a supporting structure of a compressor of a refrigerator in the prior art, as shown in fig. 3, a pressure plate 045 is eliminated, and both ends of a mounting foot plate 021 are all connected with a supporting bottom plate 01 through a screw 041 and a nut 042.

Referring to fig. 4, 5 and 6, an embodiment of the invention provides a refrigerator compressor supporting structure, which includes a supporting base plate 1, a mounting foot plate 21 is fixed on a compressor 2, a mounting hole 211 is formed in the mounting foot plate 21, a vibration isolating pad 3 is arranged on the supporting base plate 1, a through hole 31 is formed in the vibration isolating pad 3, the mounting foot plate 21 is erected on the upper end face of the vibration isolating pad 3, the supporting base plate 1 is connected with the mounting foot plate 21 through a connecting component 4, the connecting component 4 penetrates through the mounting hole 211 and the through hole 31, and the mounting foot plate 21 is separated from the connecting component 4 through a vibration isolating piece 5 in the vertical direction.
As shown in fig. 6, in the refrigerator compressor supporting structure provided in the embodiment of the present invention, since the vibration isolation pad 3 is disposed on the supporting base plate 1, and the mounting foot plate 21 is erected on the upper end surface of the vibration isolation pad 3, when the compressor 2 works, the mounting foot plate 21 vibrates on the upper end surface of the vibration isolation pad 3, and the mounting foot plate 21 and the vibration isolation pad 3 are not fixed together, so that when the mounting foot plate 21 vibrates on the upper end surface of the vibration isolation pad 3, it is difficult to drive the vibration isolation pad 3 to vibrate together with the mounting foot plate, and the vibration isolation pad 3 can weaken the vibration transmission between the mounting foot plate 21 and the supporting base plate 1 by using its own elasticity, thereby better playing the role of vibration attenuation and isolation, and further greatly reducing the noise during the refrigerator working; because the mounting foot plate 21 and the connecting assembly 4 are separated by the vibration isolating piece 5 along the vertical direction, the vibration isolating piece 5 can weaken the vibration transmission from the mounting foot plate 21 to the connecting assembly 4, so that the connecting assembly 4 is not easy to be damaged due to overlarge vibration, and the service life of the connecting assembly 4 can be prolonged.
The connection relationship between the vibration isolation pad 3 and the support base plate 1 is not exclusive, and for example, the vibration isolation pad 3 may directly overlap the support base plate 1. As shown in fig. 5, the vibration insulator 3 may be fixedly connected to the support base plate 1. Compared with the vibration isolator 3 which is directly lapped on the supporting base plate 1, the vibration isolator 3 is fixed on the supporting base plate 1, so that the through hole 31 on the vibration isolator 3 and the mounting hole 211 on the mounting foot plate 21 can be conveniently aligned when the compressor 2 is mounted (as shown in fig. 6), and the mounting foot plate 21 and the supporting base plate 1 can be conveniently connected by the connecting component 4, so that the mounting time of the compressor 2 can be shortened; meanwhile, the vibration isolation pad 3 is fixed on the support base plate 1, so that small-amplitude vibration of the vibration isolation pad 3 itself when the mounting foot plate 21 vibrates is limited, and the vibration damping and isolating effects of the vibration isolation pad 3 can be improved. Wherein, the vibration isolation pad 3 can be fixedly connected with the supporting base plate 1 through a flange.
The contact mode of the connecting component 4 with the wall of the through hole 31 in the through hole 31 is not unique, for example: the whole part of the connecting component 4 in the through hole 31 is contacted with the wall of the through hole 31. Further, the connection member 4 and the through hole 31 may be in contact with each other in the following manner: as shown in fig. 6, the hole wall of the through hole 31 is provided with a raised elastic limiting ring 32, and the elastic limiting ring 32 is in contact with the connecting component 4. Compared with the scheme that the part of the connecting component 4 in the through hole 31 is completely contacted with the hole wall of the through hole 31, the scheme shown in fig. 6 can greatly reduce the contact area between the connecting component 4 and the vibration isolator 3 because the connecting component 4 is contacted with the elastic limiting ring 32 instead of the whole through hole 31, thereby greatly weakening the vibration transmission between the vibration isolator 3 and the connecting component 4.
It should be noted that: this kind of mode of setting that elasticity spacing collar 32 and coupling assembling 4 contacted is more suitable for the embodiment that vibration isolator 3 directly overlaps on supporting baseplate 1, and except setting up like this can reduce coupling assembling 4 and vibration isolator 3's area of contact, weakens the vibration transmission between vibration isolator 3 and the coupling assembling 4, can also restrict vibration isolator 3 and radially rocking to make vibration isolator 3 exert the vibration damping and isolation effect better. And in the embodiment of vibration isolator 3 and supporting baseplate 1 fixed connection, because vibration isolator 3 is fixed on supporting baseplate 1, vibration isolator 3 is difficult to radially rock, just can not set up elasticity spacing collar 32 in the through-hole 31 of vibration isolator 3 at this moment, only need do the diameter of through-hole 31 slightly bigger, let have between coupling assembling 4 and the through-hole 31 pore wall the clearance can, coupling assembling 4 just can avoid vibration isolator 3's vibration to coupling assembling 4 transmission with vibration isolator 3 contactless like this.
The elastic spacing ring 32 may be designed separately from the vibration isolation pad 3, or may be formed integrally with the vibration isolation pad 3, which is not limited herein; the vibration insulator 3 may be made of a rubber material.
The connecting assembly 4 is also not exclusively arranged, for example, the connecting assembly 4 may be arranged in the following manner: the coupling assembly 4 includes a bolt fixed to the support base plate 1 and sequentially passing through the mounting hole 211 of the mounting leg plate 21 and the through-hole 31 of the vibration isolating pad 3, and a nut 42 engaged with a threaded portion of the bolt.
In addition, the connecting assembly 4 may also be arranged in the following manner: as shown in fig. 6, the connection assembly 4 includes a screw 41 and a nut 42, the nut 42 is fixed to the support base plate 1, and the screw 41 sequentially passes through the mounting hole 211 of the mounting foot plate 21 and the through hole 31 of the vibration isolator 3 and is engaged with the nut 42. Compared with the arrangement scheme that the connecting component 4 comprises the bolt and the nut 42, in the scheme shown in fig. 6, the nut 42 is fixed on the supporting bottom plate 1, and the nut 42 is not easy to incline and deform due to the relatively large diameter of the nut 42, so that the smooth screwing of the screw 41 is ensured, and meanwhile, due to the fact that the thread of the nut 42 is an internal thread, when the nut 42 is not matched with the screw 41, the thread is not easy to damage, so that the smooth screwing of the screw 41 is facilitated.
In the support structure of the refrigerator compressor provided by the embodiment of the invention, the number of the mounting foot plates 21 can be one, the mounting foot plates are fixed in the middle area of the bottom of the compressor 2, and the mounting foot plates 21 and the support bottom plate 1 are supported by the two vibration isolators 3. As shown in fig. 5, the number of the mounting foot plates 21 may be two, and the mounting foot plates 21 are fixed to the opposite sides of the bottom of the compressor 2, respectively, and each of the mounting foot plates 21 and the support plate is supported by two vibration isolators 3. Compare the scheme that installation sole 21 number is one, in the scheme that installation sole 21 number is two, two installation soles 21 are fixed in the relative both sides of compressor 2 bottom respectively, support through four vibration isolators 3 between compressor 2 and the supporting baseplate 1, so not only can improve the effect of vibration damping and vibration isolation of vibration isolators 3, but also can reduce the size of the effort that each vibration isolator 3 receives to be favorable to making the balance of compressor 2.
In the support structure of the refrigerator compressor provided by the embodiment of the invention, the fixing mode of the mounting foot plate 21 is not exclusive, for example, two ends of the mounting foot plate 21 can be connected with the support bottom plate 1 through the screws 41 and the nuts 42.
In addition, the mounting foot plate 21 may be fixed to the support base plate 1 in the following manner: as shown in fig. 5, the connecting assembly 4 further includes a pressing plate 43, the pressing plate 43 is disposed above the mounting foot plate 21, a first end of the pressing plate 43 is connected to the supporting base plate 1 through a screw 41 and a nut 42, and a second end of the pressing plate 43 is connected to the supporting base plate 1 through a clamping structure. Wherein, the first end of the pressure plate 43 is the end of the pressure plate 43 close to the outer side of the compressor bin (i.e. end C in fig. 4), and the second end is the end of the pressure plate 43 close to the inner side of the compressor bin (i.e. end D in fig. 4); as shown in fig. 6, the first end of the pressing plate 43 is provided with a screw hole 432, the screw hole 432 corresponds to the through hole 31 of one of the vibration isolators 3, the screw hole 432 is a long hole, and the screw hole 432 extends along the length direction of the pressing plate 43, so that the screw 41 has a certain degree of freedom along the length direction of the pressing plate 43. Compared with the fixing mode that the two ends of the mounting foot plate 21 are connected with the supporting base plate 1 through the screws 41 and the nuts 42, in the fixing mode shown in fig. 5, the second end of the pressing plate 43 is connected with the supporting base plate 1 through the clamping structure, so that the screws 41 and the nuts 42 at the second end of the pressing plate 43 can be omitted, the problem that the screws 41 are inconvenient to screw on the inner side of the compressor bin is solved, the mounting procedures of the compressor 2 can be reduced, and the mounting time is shortened.
The clamping structure is not unique, and for example, the clamping structure can be as follows: the clamping structure comprises a clamping plate arranged on the supporting bottom plate 1 and a clamping groove arranged on the pressing plate 43, a clamping hook is arranged at the upper end of the clamping plate, and the clamping plate sequentially penetrates through the through hole 31 of the vibration isolating pad 3 and the mounting hole 211 of the mounting foot plate 21 and is in matched clamping connection with the clamping groove. The second end of the pressing plate 43 is connected with the supporting bottom plate 1 by matching and clamping the clamping hook and the clamping groove.
In addition, the clamping structure can also be as follows: as shown in fig. 7 and 8: the clamping structure comprises a clamping hole 11 formed in the support base plate 1 and a clamping plate 431 formed by downward extending of the second end of the pressing plate 43, a clamping hook 4311 is formed at the lower end of the clamping plate 431, and the clamping plate 431 sequentially penetrates through the mounting hole 211 of the mounting foot plate 21 and the through hole 31 of the vibration isolator 3 and is matched and clamped with the clamping hole 11. The second end of the pressure plate 43 is also connected to the support base plate 1 by the engagement of the hooks 4311 with the engagement holes 11. The clamping hole 11 is also a long hole, and the length of the long hole is larger than the width of the clamping hook 4311, so that the clamping plate 431 can be conveniently inserted into the long hole along the length direction of the long hole during installation, and then the clamping plate 431 rotates to enable the clamping hook 4311 to be clamped with the clamping hole 11. Compare the joint structure that is equipped with the cardboard on the supporting baseplate 1, the joint structure shown in figure 8, because cardboard 431 is formed by the second end downwardly extending of clamp plate 43, when pothook 4311 takes place to damage, can conveniently change like this, is favorable to reducing cost of maintenance.
In the compressor support structure provided by the embodiment of the invention, the mounting foot plate 21 is separated from the connecting assembly 4 by the vibration isolation member 5. The type of the vibration isolation member 5 is not exclusive, and the vibration isolation member 5 may be a vibration isolation sleeve, for example. The vibration isolating sleeve may have different shapes, such as a shape like a "T", specifically, the vibration isolating piece 5 is a vibration isolating sleeve disposed in the mounting hole 211, an upper flange 51 is formed by extending an upper end of an outer side wall of the vibration isolating sleeve outwards, and the upper flange 51 is located between the mounting foot plate 21 and the pressure plate 43. Because the upper flange 51 is located between the mounting foot plate 21 and the pressure plate 43, the upper flange 51 can reduce the vibration transmitted from the mounting foot plate 21 to the pressure plate 43, thereby avoiding the pressure plate 43 from generating larger noise or being damaged due to excessive vibration.
In addition, the vibration damping sleeve may have an i shape, specifically, as shown in fig. 6, a lower flange 52 is formed to extend outward from the lower end of the outer side wall of the vibration damping sleeve, and the mounting foot plate 21 is located between the upper flange 51 and the lower flange 52. The I-shaped vibration isolation sleeve not only can weaken the vibration transmission from the mounting foot plate 21 to the pressing plate 43, but also can weaken the vibration transmission from the mounting foot plate 21 to the vibration isolation pad 3, can further reduce the vibration transmission from the mounting foot plate 21 to the supporting bottom plate 1, and is favorable for reducing the noise of the refrigerator during operation.
The vibration insulator 5 may be a vibration damping washer, which is provided between the mounting foot plate 21 and the pressing plate 43, in addition to the vibration insulator. The vibration damping gasket can also achieve the effect of damping the vibration transmitted from the mounting foot plate 21 to the pressure plate 43, thereby preventing the pressure plate 43 from generating loud noise or being damaged due to excessive vibration.
Referring to fig. 6, the first end of the pressing plate 43 is connected to the supporting base plate 1 through the screw 41 and the nut 42, and in the process of screwing the screw 41 into the nut 42, if the depth of screwing the screw 41 into the nut 42 is too large, the pressure of the pressing plate 43 on the mounting foot plate 21 is too large, and further the pressure of the mounting foot plate 21 on the vibration isolating pad 3 is too large, the vibration isolating pad 3 is easily crushed, the elasticity of the vibration isolating pad 3 is weakened, and further the vibration damping and isolating effect of the vibration isolating pad 3 is influenced to a certain extent. To solve this problem, it can be solved in two ways:
the first method is as follows: a steel sleeve is sleeved on the screw rod of the screw 41, a part of the steel sleeve extends into the through hole 31 of the vibration isolation pad 3, the upper end of the steel sleeve abuts against the pressure plate 43, and the lower end of the steel sleeve abuts against the upper end face of the nut 42. Through the arrangement, the pressing plate 43 can be supported by the steel sleeve, and the phenomenon that the vibration damping and isolating effect of the vibration isolating pad 3 is weakened due to the fact that the pressing plate 43 exerts overlarge pressure on the vibration isolating pad 3 can be avoided.
The second method comprises the following steps: as shown in fig. 6, the nut 42 is inserted into the mounting hole 211 of the mounting leg plate 21 and the through hole 31 of the vibration isolator 3, the lower end of the nut 42 is fixedly connected to the support base plate 1, the upper end of the nut 42 abuts against the pressure plate 43, and a gap is formed between the mounting hole 211 and the outer side wall of the nut 42. Through the arrangement, the nut 42 can support the pressing plate 43, and the phenomenon that the vibration damping and isolating effect of the vibration isolating pad 3 is weakened due to the fact that the pressing plate 43 exerts excessive pressure on the vibration isolating pad 3 can be avoided. The mounting hole 211 is formed with a gap from the outer side wall of the nut 42, that is, the mounting hole 211 is spaced from the outer side wall of the nut 42, so that the transmission of vibration between the mounting foot plate 21 and the nut 42 can be blocked. The nut 42 may be a high nut, and when the diameter of the thread is fixed, the axial length of the high nut is longer than that of a common nut, such as a rivet nut, and the high nut is more conveniently mounted on the support base plate 1; as shown in FIG. 6, the high nut is in contact with the elastic limiting ring 32 on the wall of the through hole 31.
Mode one and mode two can both realize the support to clamp plate 43, thereby avoid vibration isolator 3 to weaken because of receiving too big damping vibration isolation effect of pressure, but compare mode one, it is that nut 42 directly supports clamp plate 43 in the mode two, and the lower extreme and the supporting baseplate 1 fixed connection of nut 42, nut 42 keeps coaxial with vibration isolator 3's through-hole 31 easily when installation like this, be difficult to take place to rock in through-hole 31, thereby can make things convenient for the installation of compressor 2 (in mode one, the steel bushing is an independent moving part, be difficult to keep coaxial with vibration isolator 3's through-hole 31 when the installation, take place to rock easily in through-hole 31).
As shown in fig. 6, in the refrigerator compressor supporting structure provided by the embodiment of the present invention, the contact manner between the nut 42 and the elastic limiting ring 32 can greatly reduce the vibration transmitted from the vibration isolation pad 3 to the nut 42, and avoid the vibration from being transmitted from the nut 42 to the pressing plate 43 and the supporting base plate 1, so that the actual vibration transmission path of the compressor 2 is close to the theoretical transmission path (i.e., the compressor 2, the vibration isolation sleeve, the vibration isolation pad 3 and the supporting base plate 1), and thus the vibration isolation pad 3 can exert the vibration attenuation and vibration isolation function to the maximum extent, and further reduce the noise during the operation of the refrigerator.
On the other hand, the embodiment of the invention also provides a refrigerator, which comprises the refrigerator compressor supporting structure of any one of the embodiments.
