Detailed Description
It should be noted that the directional indications (such as up, down, left, right, front, and back … …) involved in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.
The present invention provides a compressor assembly which can be used in an air conditioner, such as a split air conditioner or an all-in-one air conditioner, and it is conceivable that the compressor assembly is provided in an outdoor unit when the air conditioner is a split air conditioner.
In an embodiment of the present invention, referring to fig. 1 to 3, the compressor assembly includes a compressor 20, a liquid storage tank 40, a connecting pipe 60, a sealing ring 70, and the like.
In this embodiment, the liquid storage tank 40 is communicated with the compressor 20 through a connection pipe 60, specifically, an air outlet (not labeled) is provided on the liquid storage tank 40, the air outlet is generally disposed at the bottom of the liquid storage tank 40, the connection pipe 60 has a first end 61 and a second end 62 opposite to each other, the first end 61 is connected with the compressor 20, and the second end 62 is connected with the air outlet. The receiver 40 is used for separating gaseous refrigerant from liquid refrigerant, so that the compressor 20 can normally suck gaseous refrigerant for compression and transportation.
To reduce the transmission of vibrations from the compressor 20 to the reservoir 40, in one embodiment, a gasket 70 is provided at the junction of the second end 62 and the outlet port, and the second end 62 is sealingly connected to the outlet port by the gasket 70, such that the gasket 70 spaces the second end 62 from the reservoir 40. Generally, the connecting pipe 60 may be a copper pipe, and the vibration of the compressor 20 may be transmitted to the liquid storage tank 40 through the copper pipe, therefore, in the embodiment, the connecting pipe 60 and the liquid storage tank 40 are hermetically connected through the sealing ring 70, which not only can effectively prevent the refrigerant from leaking, but also can isolate the vibration of the compressor 20 from being transmitted to the liquid storage tank 40. In one embodiment, the sealing ring 70 is sleeved on the second end 62 and is in sealing contact with the hole wall of the air outlet, i.e. the sealing ring 70 is in sealing contact with the outer peripheral surface of the connecting pipe 60 and the hole wall of the air outlet respectively. In other embodiments, a ring of air outlet nozzles may be disposed on the liquid storage tank 40 and around the air outlet, the sealing ring 70 may be sleeved on the outer circumferential surface of the air outlet nozzles, and the connecting pipe 60 is hermetically sleeved on the outer circumferential surface of the sealing ring 70. In the above, the sealing ring 70 may be made of silicone rubber, or the like, and for example, the sealing ring 70 may be made of nitrile rubber.
In this embodiment, the connection pipe 60 of the compressor 20 and the liquid storage tank 40 is provided with the sealing ring 70, and the sealing ring 70 separates the connection pipe 60 from the liquid storage tank 40, so that the connection pipe 60 is prevented from directly contacting the liquid storage tank 40, and therefore, the vibration generated by the compressor 20 can be greatly reduced and transmitted to the liquid storage tank 40 through the connection pipe 60, thereby further reducing the vibration of the liquid storage tank 40.
In order to prevent the sealing ring 70 from falling out of the liquid storage tank 40 under a large pressure, in one embodiment, the aperture of the air outlet is gradually reduced from the inside of the liquid storage tank 40 to the outside, namely, the air outlet is in a circular truncated cone shape with a large upper end and a small lower end; the outer diameter of the gasket 70 matches the diameter of the outlet port, i.e., the outer diameter of the gasket 70 decreases gradually in a direction toward the outside of the outlet port (i.e., in a direction away from the reservoir tank 40), i.e., the gasket 70 is wedge-shaped. Because the outer diameter of the inner end of the sealing ring 70 is larger and the outer diameter of the outer end is smaller, even if the sealing ring 70 is subjected to a larger downward pressure in the liquid storage tank 40, the larger end of the sealing ring 70 can be abutted against the hole wall of the air outlet and is limited by the hole edge of the air outlet, so that the sealing ring is prevented from falling off. It should be noted that, because the sealing ring 70 has elasticity, when assembling, the sealing ring 70 can be sleeved on the second end 62, and the sealing ring 70 can be obliquely pressed to be installed in the liquid storage tank 40, and after the sealing ring 70 is laid flat, the sealing ring can be well abutted to the hole edge of the air outlet, so as to achieve a sealing effect.
To further prevent the seal ring 70 from falling off, in an embodiment, the compressor assembly further includes a fixing ring (not shown) disposed at the second end 62 and abutting against an exposed end surface of the seal ring 70. This corresponds to the effect of the retaining ring bearing the sealing ring 70 on the outside, further preventing it from falling off. In this embodiment, the fixing ring is a nut, and the outer peripheral surface of the second end 62 is provided with an external thread to be engaged with the nut. In other embodiments, the fixing ring is welded to the connecting tube 60.
To facilitate the fixing between the connection pipe 60 and the sealing ring 70, in an embodiment, the outer diameter of the second end 62 is gradually increased in a direction away from the first end 61, which is equivalent to making the second end 62 form an expanding section, so that after the second end 62 is inserted into the inner hole of the sealing ring 70, the second end 62 can press the sealing ring 70 in a direction close to the first end 61 and in a direction toward the outer periphery of the sealing ring 70, so that the sealing ring 70 gives a reaction force to the second end 62, the reaction force is inclined with respect to the axial direction of the sealing ring 70, and thus the second end 62 is better limited from being separated from the sealing ring 70 along the axial direction of the sealing.
In the embodiment of the present invention, during the specific assembly, the inner surfaces of the connecting pipe 60 and the liquid storage tank 40 are cleaned; the o-ring 70 is then fitted over the second end 62 of the connector tube 60, and the o-ring 70 is then installed into the reservoir 40, with the o-ring 70 positioned so that it abuts the inner peripheral wall of the outlet and abuts the outer peripheral surface of the connector tube 60. Finally, the sealing ring 70 is locked by the fixing ring, so that the liquid storage tank 40 and the connecting pipe 60 are completely and hermetically fixed.
In one embodiment, the compressor assembly further includes a damping shell 30, the damping shell 30 is mounted on the base plate 10, and the damping shell 30 is sleeved outside the compressor 20 and forms a noise reduction gap 54 with an outer wall of the compressor 20. In the present embodiment, the damper housing 30 has a shape that is similar to, i.e., identical to, the outer shape of the compressor 20. Because each pipeline is connected to the compressor 20, in order to facilitate the extension of the pipeline, the top of the damper housing 30 is open, the top of the compressor 20 protrudes out of the damper housing 30 through the opening of the damper housing 30, and the noise reduction gap 54 is formed between the peripheral wall of the damper housing 30 and the peripheral wall of the compressor 20. The noise reduction gap 54 can isolate noise generated during the operation of the compressor 20, thereby effectively reducing noise transmitted from the compressor 20 to the outside and further improving the noise reduction performance of the outdoor unit of the air conditioner.
In the present embodiment, the width of the noise reduction gap 54 is 8mm to 12 mm. For example, the width L of the noise reduction gap 54 may be 8mm, 10mm, 12mm, etc., if the width L of the noise reduction gap 54 is less than 8mm, the noise reduction gap 54 is too small, resulting in poor isolation effect, and when the sound-absorbing medium 51 is filled in the noise reduction gap 54, resulting in too small filling amount of the sound-absorbing medium 51, poor noise reduction effect; if the width L of the noise reduction gap 54 is greater than 12mm, the space of the air conditioner case will be occupied too much; therefore, setting the width L of the noise reduction gap 54 to 8mm to 12mm makes it possible to make the width L of the noise reduction gap 54 more reasonable while ensuring effective noise reduction and sound absorption.
In this embodiment, the damping shell 30 is made of a material with a large thickness, for example, the damping shell 30 is made of a material with a large density such as steel or lead, and the sound insulation effect is better. The thickness of the damper housing 30 is 2mm to 4mm, for example, the thickness of the damper housing 30 is 2mm, 3mm, or 4mm, etc. If the wall thickness of the damping shell 30 is less than 2mm, the structural strength is weak, and the sound insulation effect is poor; if the wall thickness of the damping shell 30 is larger than 4mm, the processing materials are increased, and the production cost is higher; therefore, the wall thickness of the vibration shell is set to be 2mm to 4mm, and the wall thickness of the vibration shell 30 can be more reasonable on the basis of ensuring effective noise reduction and sound absorption.
In one embodiment, the noise reduction gap 54 is filled with the sound-absorbing medium 51, and the sound-absorbing medium 51 can effectively absorb the noise transmitted through the noise reduction gap 54. In this embodiment, the sound-absorbing medium 51 may be a porous material such as foam or soundproof cotton, and mainly absorbs noise. In this embodiment, the sound-absorbing medium 51 fills the noise reduction gap 54 to improve the sound-absorbing and noise-reducing effects.
In the invention, the compressor 20 is arranged in the shock absorption shell 30, the shock absorption shell 30 prevents part of the vibration noise generated in the operation process of the compressor 20 from being transmitted to the outside, and the sound absorption medium 51 is filled between the shock absorption shell 30 and the compressor 20, so that the sound absorption effect of the sound absorption medium 51 is better, the vibration noise generated by the compressor 20 can be effectively absorbed, the transmission of the vibration noise generated by the compressor 20 is greatly weakened, the whole vibration of the air conditioner is weakened, and the whole performance of the air conditioner is improved.
In one embodiment, the outer peripheral wall of the compressor 20 is further sleeved with a damping ring 53, and the damping ring 53 abuts against the inner peripheral wall of the damping shell 30. In this embodiment, the inner diameter of the damping ring 53 is the same as the outer diameter of the compressor 20, and the outer diameter of the damping ring 53 is the same as the inner diameter of the damping shell 30, so that the damping ring 53 can be abutted against the compressor 20 and the damping shell 30 at the same time, and noise is prevented from being transmitted upward from the noise reduction gap 54 and transmitted to the indoor unit along a pipeline connected to the upper end. Alternatively, the dampening ring 53 is located near the top of the compressor 20 such that the overall volume of the dampening gap 54 below the dampening ring 53 is greater and the dampening capability for noise is greater, and the dampening ring 53 blocks more noise within the dampening gap 54 below the dampening ring 53, which can reduce noise transmission upwards even more.
In one embodiment, the distance H from the shock absorbing ring 53 to the top end of the shock absorbing shell 30 is 30mm-50mm, for example, the distance H from the shock absorbing ring 53 to the top end of the shock absorbing shell 30 is 30mm, 43mm or 50 mm. If the damping ring 53 is too close to the top end of the damping shell 30, the damping ring 53 has a poor clamping effect on the compressor 20, easily shakes off the compressor 20, and is not beneficial to preventing the compressor 20 and the damping shell 30 from shaking each other. If the vibration ring 53 is too close to the bottom of the vibration damping housing 30, the position between the compressor 20 and the top of the vibration damping housing 30 is not limited, and the vibration between the compressor 20 and the vibration damping housing 30 is large. Therefore, in the embodiment, the distance H from the shock absorbing ring 53 to the top end of the shock absorbing shell 30 is limited to 30mm-50mm, which can avoid the above phenomenon.
In one embodiment, the sound absorbing medium 51 is filled under the damping ring 53. In this embodiment, the damping ring 53 is respectively abutted against the compressor 20 and the damping shell 30, which is equivalent to separating the noise reduction gap 54 into an upper section and a lower section, and the upper section is generally open due to the requirement of pipeline installation, i.e. the damping ring 53 blocks more noise at the lower section, and then the noise reduction gap 54 at the lower section is filled with the sound absorption medium 51, so that a better noise reduction effect can be achieved. Of course, in other embodiments, the sound absorbing medium 51 may be disposed both above and below the dampening ring 53.
In one embodiment, a shock absorbing pad 52 is further disposed between the base plate 10 and the bottom surface of the compressor 20. In the present embodiment, the damping pad 52 and the damping ring 53 can be made of a material with a relatively high damping ratio, such as a rubber material or a damping spring, so as to effectively reduce the vibration transmitted from the compressor 20 to the damping shell 30 and reduce the noise generated by the vibration. In addition, the shock absorbing pad 52 can also buffer the impact between the shock absorbing shell 30 and the compressor 20 during the transportation and landing of the outdoor unit of the air conditioner, so as to effectively protect the compressor 20 and improve the stability of the outdoor unit of the air conditioner. In the above, the cushion 52 and the cushion ring 53 mainly play a role of damping vibration, i.e., preventing the compressor 20 from vibrating, thereby reducing the transmission of vibration.
In one embodiment, the fluid reservoir 40 is located outside the shock absorbing shell 30, and the fluid reservoir 40 is attached and fixed to the outer surface of the shock absorbing shell 30. Optionally, the liquid storage tank 40 is welded with the damping shell 30, specifically, the top of the liquid storage tank 40 is welded with the damping shell 30, so that the liquid storage tank 40 is rigidly connected with the damping shell 30, the rigidity of the assembly body is increased, and the risk of low-frequency resonance is avoided. In the embodiment, the noise of the whole air conditioner outdoor unit can be effectively reduced by effective vibration and noise reduction measures. In other embodiments, reservoir 40 may be secured to the outer wall of shock shell 30 by clips.
The present invention further provides an air conditioner, which includes a compressor component, and the specific structure of the compressor component refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, the air conditioner at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein. The air conditioner can be a split machine or an all-in-one machine.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
