Description

Technical Field

[0001] This application belongs to the technical field of air conditioning, and particularly relates to an outdoor unit of an air conditioner. Background Technology

[0002] The compressor is the core component of an air conditioning system, responsible for compressing and transporting the refrigerant. It transforms the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant, which is then delivered to the condenser, thus driving the entire cooling or heating cycle. Typically, the compressor is located inside the outdoor unit of the air conditioner, and the stable operation of the outdoor unit largely depends on the proper functioning of the compressor.

[0003] Compressors inevitably vibrate during operation, and this vibration is transmitted along the connecting pipes to the entire air conditioning system. This can cause wear and loosening of the pipes, and even pipe rupture, severely impacting the normal operation and lifespan of the air conditioner. Furthermore, the noise generated by this vibration can cause noise pollution, interfering with people's lives and work.

[0004] To reduce the negative impact of compressor vibration, rubber vibration isolation structures are typically installed at the base or support of compressors. Since these structures are located at the bottom of the compressor, they also need to support it to prevent swaying during outdoor unit transportation. However, there is an inherent contradiction between the vibration reduction performance and the support function of the vibration isolation structure. If the focus is on improving the vibration isolation effect by using softer materials or reducing stiffness, its support performance often deteriorates. Conversely, if too much emphasis is placed on support and a stiffer design is used, the vibration reduction effect will be significantly reduced.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0006] In view of the shortcomings of the related technologies, this application provides an air conditioner outdoor unit that designs the vibration isolation structure to include a vibration isolation component and a sleeve, with the sleeve located inside the vibration isolation component and engaging with the vibration isolation component through an inclined surface, so that the sleeve and the vibration isolation component cooperate with each other, thereby increasing the vibration isolation effect of the vibration isolation component.

[0007] This application provides an outdoor unit for an air conditioner, comprising:

[0008] The housing includes a housing air inlet and a housing air outlet. The housing air inlet is located on the outer periphery of the housing, and the housing air outlet is located on the front side of the housing.

[0009] The heat exchanger is located inside the casing, with its windward side facing the air inlet of the casing.

[0010] The fan is located inside the casing, on the leeward side of the heat exchanger, with its outlet facing the air outlet of the casing.

[0011] The compressor, located inside the casing, is used to drive the flow of refrigerant within the heat exchanger; a connecting component is attached to the bottom of the compressor.

[0012] The vibration isolator has its upper end connected to the connector and its lower end connected to the bottom of the housing; the inner wall of the vibration isolator is provided with a contact part.

[0013] The sleeve is located inside the vibration isolator, and the bottom surface of the sleeve and the housing are isolated from each other by the bottom wall of the vibration isolator; the outer periphery of the sleeve is provided with a support part, which contacts the contact part so that the sleeve supports the vibration isolator.

[0014] The mating surface between the support and the contact part is an inclined surface that slopes upward toward the central axis of the vibration isolator.

[0015] This technical solution incorporates vibration isolation components that are connected to the connecting components. This allows the vibration isolation components to block the vibrations generated by the compressor and reduce the vibrations transmitted by the compressor. By incorporating a sleeve within the vibration isolation components, the sleeve provides support for the components, preventing excessive deformation that could cause the compressor to shake. This ensures that the vibration isolation components possess both good vibration isolation performance and excellent vibration reduction capabilities.

[0016] In some embodiments, a first plane is defined, which is perpendicular to the central axis of the vibration isolator;

[0017] The contact portion is defined by a first mating surface, and the support portion is defined by a second mating surface, which is in contact with the first mating surface. The first mating surface and the first plane are defined by an angle α, and the second mating surface and the first plane are defined by an angle β, where the angles α and β satisfy: α ≥ β.

[0018] This technical solution achieves a progressive contact support by ensuring that α ≥ β. When the contact part and the support part mate, a progressive contact support is formed. Under the action of vibration load, the vibration isolation component will gradually fit along the second mating surface, making the force more uniform. This allows the sleeve to better support the vibration isolation component and reduces the sway amplitude of the vibration isolation component caused by vibration. At the same time, more vibration energy is dissipated through the friction of the inclined surface.

[0019] In some embodiments, the vibration isolator includes a body and a connector, the connector is located on the top of the body, the interior of the connector is connected to the interior of the body, and the outer diameter of the connector is smaller than the outer diameter of the body.

[0020] The connector has a connecting part, which is sleeved on the outer periphery of the connector head, and the inner diameter of the connecting part is smaller than the outer diameter of the body, so that the connector can be connected to the vibration isolation member.

[0021] This technical solution uses a connector to connect the connector and the connector; by providing a connecting part in the connector, the connector is fitted around the outer periphery of the connector, and the inner diameter of the connecting part is smaller than the outer diameter of the body, so that the body limits the connector and prevents the connecting part from detaching from the body and the connector.

[0022] In some embodiments, the upper end of the connector is provided with a blocking part, and the blocking part has a gap with the top of the body; the gap is used to limit the setting position of the connector part, and the outer diameter of the blocking part is larger than the outer diameter of the connector part.

[0023] This technical solution provides a blocking part at the upper end of the connector, with the outer diameter of the blocking part being larger than the outer diameter of the connector, to prevent the connector from detaching from the upper end of the connector and to increase the reliability of the connection between the connector and the vibration isolation component.

[0024] In some embodiments, the inner diameter of the connector is D0, the outer diameter of the connector is D1, the inner diameter of the connector is D2, the outer diameter of the upper end of the sleeve is D3, and D1-D0≤0.5*(D2-D3).

[0025] This technical solution ensures that D1-D0≤0.5*(D2-D3) to create a gap between the connector and the upper end of the sleeve, preventing them from contacting each other. This allows the vibration energy to be mainly absorbed and attenuated by the vibration isolation component, preventing vibration from being transmitted downwards from the sleeve.

[0026] In some embodiments, the sleeve includes a base, a middle section, and an end. The base is located inside the body, the middle section is used to connect the base and the end, and the support is located on the outer peripheral wall of the middle section; the end is located inside the connector.

[0027] This technical solution designs the sleeve to include a base, a middle section, and an end, with the base located inside the main body and the end located inside the connector, so that the sleeve can be adapted to the structure of the vibration isolator. By setting the middle section to connect the base and the end, and setting the support part on the outer peripheral wall of the middle section, the middle section can contact the vibration isolator, thereby increasing the support effect of the sleeve on the vibration isolator.

[0028] In some embodiments, the sleeve further includes a transition section located at the connection between the intermediate section and the base; the outer diameter of the transition section is smaller than the outer diameter of the base and larger than the outer diameter of the end.

[0029] This technical solution sets up a transition section to form a buffer zone between the base and the middle section, avoiding stress concentration caused by sudden rigidity changes, and allowing vibration energy to be attenuated in stages during transmission. It provides graded support when the compressor vibrates with large amplitude, ensuring flexible vibration isolation during normal operation, and limiting excessive deformation of the vibration isolation components under impact conditions through the stepped structure of the transition section, preventing the compressor from exceeding displacement limits and damaging the pipeline. At the same time, it optimizes the overall weight distribution of the sleeve.

[0030] In some embodiments, the outer diameter D1 of the connector and the outer diameter D4 of the transition section satisfy the relationship: D1≥D4.

[0031] This technical solution reduces the downward transmission of axial vibration through the sleeve joint by ensuring that D1 ≥ D4.

[0032] In some embodiments, the vibration isolator has a first recess and a second recess, which extend circumferentially along the vibration isolator, respectively; the first recess is located on the outer peripheral wall of the vibration isolator, and the second recess is located on the inner peripheral wall of the vibration isolator; the first recess and the second recess are offset from each other along the axial direction of the vibration isolator.

[0033] This technical solution provides a first recess on the outer peripheral wall of the vibration isolator, extending circumferentially along the vibration isolator. This causes the vibration isolator to deform and protrude inwards when subjected to vibration, thereby increasing the interference fit between the vibration isolator and the sleeve, increasing the friction between them, and thus enhancing the vibration reduction effect of the vibration isolator and the support effect of the sleeve. Furthermore, a second recess is provided on the inner peripheral wall of the vibration isolator, offset from the first recess along the axial direction of the vibration isolator. This causes the vibration isolator to deform and protrude inwards when subjected to vibration, further increasing the interference fit between the vibration isolator and the sleeve.

[0034] In addition, this application also provides an outdoor unit for an air conditioner, comprising:

[0035] The housing includes a housing air inlet and a housing air outlet. The housing air inlet is located on the outer periphery of the housing, and the housing air outlet is located on the front side of the housing.

[0036] The fan is located inside the casing, with its outlet facing the air outlet of the casing.

[0037] The heat exchanger is located inside the casing, with its windward side facing the air inlet of the casing; at least part of the heat exchanger's leeward side faces the air inlet of the fan.

[0038] The compressor, located inside the casing, is used to drive the flow of refrigerant within the heat exchanger; a connecting component is attached to the bottom of the compressor.

[0039] Vibration isolation assembly, which is disposed between the compressor and the bottom surface of the casing; the vibration isolation assembly includes:

[0040] The vibration isolator has its upper end connected to the connector and its lower end connected to the bottom of the housing. The vibration isolator is used to absorb the vibration generated by the compressor. The inner wall of the vibration isolator has a contact portion, which defines a first mating surface.

[0041] A sleeve is located inside the vibration isolator; the sleeve and the bottom surface of the housing are isolated from each other by the bottom wall of the vibration isolator; a support portion is provided on the outer periphery of the sleeve, and the support portion defines a second mating surface; the first mating surface and the second mating surface are in contact with each other, and the first mating surface and the second mating surface are respectively inclined surfaces that are inclined upward toward the central axis of the vibration isolator.

[0042] This technical solution decomposes the compressor vibration into axial and radial components by fitting the vibration isolator with the inclined surface of the sleeve, and effectively attenuates the vibration transmission through frictional energy dissipation. By designing the first and second mating surfaces as inclined surfaces that are inclined upward toward the central axis of the vibration isolator, the vibration isolator can elastically absorb vibration, and the rigid support of the sleeve suppresses low-frequency large-amplitude vibration, preventing the compressor from shaking excessively.

[0043] In the above embodiments, an outdoor unit of an air conditioner adopts a vibration isolation method combining a vibration isolator and a sleeve, so that the compressor of the vibration isolator absorbs or isolates vibration energy; the sleeve is set inside the vibration isolator, and the support part and the contact part cooperate through an inclined surface that is inclined upward toward the central axis of the vibration isolator. This not only supports the vibration isolator and prevents it from excessively deforming and causing the compressor to shake, but also decomposes the vibration through the inclined surface, consumes the vibration energy by friction, and reduces the vibration transmitted to the casing, thereby effectively improving the operating stability and vibration reduction performance of the outdoor unit of the air conditioner.

[0063] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0064] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0065] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0066] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0067] The outdoor unit of the air conditioner provided in this application can have various implementation forms, such as a side-discharge type outdoor unit or a top-discharge type outdoor unit. Figures 1-4 This is one specific implementation of the outdoor unit of the air conditioner in this application.

[0068] like Figure 1 As shown, the outdoor unit of the air conditioner provided in this application includes a housing 100, which forms the overall appearance of the outdoor unit. The top and bottom of the housing 100 are opposite ends, and the height direction of the housing 100 is from the top to the bottom. The left and right sides of the housing 100 are opposite sides, and the length direction of the housing 100 is from the left to the right. The front and rear sides of the housing 100 are opposite sides, and the thickness direction of the housing 100 is from the front to the rear.

[0069] like Figure 2 As shown, the housing 100 includes a top plate 110, which is located at the top of the housing 100 and forms the top surface of the housing 100.

[0070] like Figure 3 As shown, the housing 100 includes a bottom plate 140, which is located at the bottom of the housing 100 and forms the bottom surface of the housing 100; the bottom plate 140 and the top plate 110 are arranged opposite to each other along the height direction of the housing 100.

[0071] like Figure 2 As shown, the housing 100 includes a front panel 120, which is located on the front side of the housing 100 and forms the front side surface of the housing 100.

[0072] The housing 100 includes a rear side panel located at the rear of the housing 100, which forms the rear side surface of the housing 100. It should be noted that in some embodiments, the housing 100 may not include a rear side panel to increase the air intake volume of the outdoor unit of the air conditioner.

[0073] like Figure 2 and Figure 3 As shown, the housing 100 includes a first side plate 130, which is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0074] The housing 100 includes a second side plate, which is disposed opposite to the first side plate 130 along the length of the housing 100; the second side plate is located on the left or right side of the housing 100 and is used to form the left or right side of the housing 100.

[0075] It should be noted that the first side plate 130 and the second side plate are respectively located on different sides of the casing 100 in the length direction. In this embodiment, the first side plate 130 is located on the left side of the casing 100, the second side plate is located on the right side of the casing 100, and part of the casing air outlet 102 is located on the second side plate.

[0076] like Figure 3 As shown, the housing 100 includes a partition 150, which is located inside the housing 100. The partition 150 is arranged along the height direction of the housing 100 and divides the interior of the housing 100 into a first chamber and a second chamber.

[0077] like Figure 1 As shown, the housing 100 includes a housing air inlet 101, which is connected to the first chamber. Air from outside the housing 100 enters the housing 100 through the housing air inlet 101.

[0078] There are multiple ways to position the air inlet 101 in the housing. One way is to position it on the rear side of the housing 100. Another way is to position it not only on the rear side of the housing 100, but also on the side wall of the first chamber away from the second chamber.

[0079] like Figure 2 As shown, the housing 100 includes a housing air outlet 102, which is located on the front side of the housing 100 and communicates with the first chamber. Air inside the housing 100 is output to the outside through the housing air outlet 102.

[0080] like Figure 2 and Figure 3 As shown, the outdoor unit of the air conditioner includes a fan 300, which is located in the first chamber, with the air outlet side of the fan 300 facing the air outlet 102 of the casing. Through the operation of the fan 300, external air is introduced into the casing 100 through the casing air inlet 101 and / or air inside the casing 100 is discharged to the outside of the casing 100 through the casing air outlet 102.

[0081] In this embodiment, the fan 300 is an axial flow fan 300, and the rotation axis of the fan 300 is set along the thickness direction of the casing 100.

[0082] like Figure 1 As shown, the outdoor unit of the air conditioner includes a fan cover 200, which is located at the air outlet 102 of the casing and is installed on the front panel 120. The fan cover 200 can protect the fan 300 from entering the casing 100 through the air outlet 102 and contacting the fan 300, thus affecting the normal operation of the fan 300. On the other hand, it can concentrate the air drawn in by the fan 300, thereby increasing the speed and pressure of the air and ultimately increasing the air output of the fan. In other words, the fan cover 200 can focus the air out, improve the heat dissipation effect, and make the cooling and heating effects better.

[0083] like Figure 3 As shown, the outdoor unit of the air conditioner includes a heat exchanger 400, which is located inside the casing 100. The heat exchanger 400 is used to exchange heat with the air passing through it. The heat exchanger 400 is placed on the base plate 140, with the windward side of the heat exchanger 400 facing the air inlet 101 of the casing, and at least part of the leeward side of the heat exchanger 400 facing the air inlet side of the fan 300. The operation of the fan 300 accelerates the heat exchange between the air and the heat exchanger 400, thereby increasing the heat exchange effect of the heat exchanger 400.

[0084] The heat exchanger 400 extends from the left side of the casing 100, past the rear side, to a position near the right side of the casing 100. This increases the heat exchange area of ​​the heat exchanger 400 without changing the internal space of the casing 100, thereby increasing its heat exchange efficiency. It should be noted that the extension direction of the heat exchanger 400 is its length.

[0085] like Figure 3 and Figure 4 As shown, the outdoor unit of the air conditioner includes a compressor 500, which is located in the second chamber and connected to the base plate 140. The compressor 500 is used to drive the flow of refrigerant.

[0086] Vibration is inevitable during the operation of compressor 500. If compressor 500 is directly connected to housing 100, the vibration generated by compressor 500 will be transmitted to housing 100 and other components connected to housing 100. This will not only easily cause damage to other components, but also easily generate noise and reduce the user experience.

[0087] Based on this, such as Figure 5 As shown, the outdoor unit of the air conditioner includes a vibration isolation component 600, which is located on the vibration transmission path and is used to reduce the vibration transmitted by the compressor 500.

[0088] like Figure 6As shown, the vibration isolation assembly 600 includes a vibration isolation element 610, which is usually made of a soft material such as rubber or silicone. The vibration energy of the compressor 500 is absorbed by the deformation of the vibration isolation element 610, thus blocking the transmission of vibration.

[0089] To facilitate the connection between the compressor 500 and the vibration isolation component 610, such as Figure 5 As shown, the bottom of the compressor 500 is connected to the connector 501, the upper end of the vibration isolator 610 is connected to the connector 501, and the lower end of the vibration isolator 610 is connected to the bottom of the housing 100, so that the vibration isolator 610 reduces the vibration transmitted from the compressor 500 to the housing 100.

[0090] Since the vibration isolator 610 is connected to the connector 501, when the compressor 500 vibrates, the vibration is transmitted to the vibration isolator 610 through the connector 501. After being vibrated, the vibration isolator 610 is prone to compression deformation, which makes the compressor 500 prone to shaking. Therefore, the vibration isolator 610 also needs to have a certain rigidity to ensure the stability of the compressor 500 and prevent the compressor 500 from shaking during the transportation of the outdoor unit of the air conditioner.

[0091] Based on this, such as Figure 6 As shown, the vibration isolation assembly 600 includes a sleeve 620, which is disposed inside the vibration isolation member 610. The sleeve 620 is used to support the vibration isolation member 610 to increase the rigidity of the vibration isolation member 610 and prevent the vibration isolation member 610 from undergoing large deformation. Thus, while ensuring the vibration reduction effect of the vibration isolation member 610, the vibration isolation member 610 provides good support for the compressor 500, prevents the compressor 500 from shaking, and increases the robustness and reliability of the compressor 500.

[0092] It should be noted that the bottom wall of the vibration isolator 610 can prevent the sleeve 620 from coming off downwards. The sleeve 620 and the base plate 140 are isolated from each other by the bottom wall of the vibration isolator 610 to avoid direct contact between the sleeve 620 and the housing 100.

[0093] By designing the vibration isolation assembly 600 to include a vibration isolation element 610 and a sleeve 620, the vibration isolation element 610 absorbs high-frequency vibrations through elastic deformation, and the sleeve 620 suppresses low-frequency large-amplitude vibrations through rigid support, thereby reducing the transmission of vibrations to the housing 100 and preventing the housing 100 from resonating and generating additional noise.

[0094] In order for the sleeve 620 to provide support for the vibration isolator 610, such as Figure 9 As shown, the inner wall of the vibration isolator 610 is provided with a contact portion 614, which is in contact with the outer periphery of the sleeve 620 so that the sleeve 620 supports the vibration isolator 610 through the contact portion 614.

[0095] like Figure 11As shown, the sleeve 620 has a support portion 625 on its outer periphery. The support portion 625 is in contact with the contact portion 614, and the mating surface of the two is an inclined surface that is inclined upward toward the central axis of the vibration isolator 610. By making the contact portion 614 and the inclined surface of the support portion 625 fit together, the excessive deformation of the vibration isolator 610 is limited, and the vibration isolator 610 is prevented from tearing or failing due to the large amplitude vibration of the compressor 500.

[0096] Specifically, the contact portion 614 is defined with a first mating surface, which is an inclined surface that is inclined upward toward the central axis of the vibration isolator 610.

[0097] The support portion 625 is defined by a second mating surface, which is an inclined surface that is inclined upward toward the central axis of the vibration isolator 610.

[0098] The contact portion 614 and the support portion 625 are in contact with each other through the first mating surface and the second mating surface, so that the vibration isolator 610 can play a role in frictional vibration reduction for axial and circumferential vibration.

[0099] When the compressor 500 vibrates, the vibration is transmitted to the vibration isolator 610 through the connector 501. The vibration transmitted to the vibration isolator 610 is decomposed into axial and radial components by the cooperation of the contact part 614 and the support part 625. The axial component is transmitted through the inclined plane and dispersed by pressure; the radial component causes the lateral deformation of the vibration isolator 610, allowing the vibration isolator 610 to absorb part of the vibration. Furthermore, since the contact part 614 and the support part 625 are engaged by the inclined plane, the sliding tendency of the inclined plane converts part of the vibration energy into frictional dissipation, further reducing the vibration amplitude transmitted to the housing 100.

[0100] like Figure 9 As shown, a first plane 604 is defined, which is perpendicular to the central axis of the vibration isolator 610; the first mating surface and the first plane 604 are defined by an angle α; as shown Figure 11 As shown, the second mating surface and the first plane 604 define an included angle β, and the included angle α and included angle β satisfy: α≥β. When the contact part 614 and the support part 625 are mated, a progressive contact support will be formed. That is, under the action of vibration load, the vibration isolation member 610 will gradually fit along the second mating surface, so that the force is more uniform, so that the sleeve 620 can better support the vibration isolation member 610, and also reduce the swing amplitude of the vibration isolation member 610 caused by vibration. At the same time, more vibration energy is dissipated through the friction of the inclined surface.

[0101] If α < β, the inclination angle of the first mating surface is smaller than that of the second mating surface, and the two cannot fit together completely. This will reduce the actual mating area between the sleeve 620 and the vibration isolator 610, and the sleeve 620 will not be able to provide good support for the vibration isolator 610. It will also easily lead to stress concentration, which may accelerate the wear or fatigue cracking of the vibration isolator 610 or the sleeve 620.

[0102] In some embodiments, the included angle β satisfies: β≥45°, so that the sleeve 620 can better support the vibration isolator 610.

[0103] like Figure 9 and Figure 11 As shown, the dimensions L1 of the first mating surface and L2 of the second mating surface satisfy the relationship: L1≤L2, so that the support part 625 can fully contact the contact part 614, increasing the support effect of the sleeve 620 on the vibration isolation member 610, and also making the vibration load evenly distributed, avoiding excessive local stress.

[0104] If L1 > L2, the size of the contact portion 614 is larger than the size of the support portion 625. This will reduce the effective support area when the contact portion 614 contacts the support portion 625, and the sleeve 620 will not be able to provide adequate support for the vibration isolator 610. The pressure will be concentrated in a localized area at the edge of the sleeve 620. Furthermore, an excessively large first mating surface may cause the vibration isolator 610 to deform excessively under stress, weakening its lateral stability, reducing the rigidity of the vibration isolator 610, and affecting the vibration reduction effect.

[0105] In some embodiments, the contact portion 614 is an inclined surface provided on the inner wall of the vibration isolator 610, and the support portion 625 is an inclined surface provided on the outer peripheral wall of the sleeve 620.

[0106] like Figure 8 and Figure 9 As shown, the vibration isolation member 610 includes a body 611, which is in contact with the base plate 140.

[0107] like Figure 9 As shown, the vibration isolation member 610 includes a connector 613, which is located on the top of the body 611 and is used to connect with the connector 501. The interior of the connector 613 is in communication with the interior of the body 611, and the outer diameter of the connector 613 is smaller than the outer diameter of the body 611.

[0108] The connector 501 is provided with a connecting part, which is sleeved on the outer periphery of the connector 613 so that the connector 501 is connected to the vibration isolation member 610.

[0109] The inner diameter D0 of the connecting part and the outer diameter D1 of the connector 613 satisfy: D0≤D1, so that the connector 501 and the connector 613 are interference fit, thereby increasing the firmness of the connection between the connector 501 and the vibration isolation member 610, and further increasing the firmness of the compressor 500 and preventing the compressor 500 from shaking.

[0110] The inner diameter of the connecting part is smaller than the outer diameter of the body 611 so that the body 611 provides support and limits the connector 501, preventing the connector 501 from moving downward and detaching from the connector head 613, and increasing the reliability of the connection between the connector 501 and the vibration isolation member 610.

[0111] In some embodiments, the connecting portion is a connecting hole provided in the connector 501, and the direction of the connecting hole is set along the height direction of the housing 100.

[0112] like Figure 8 and Figure 9 As shown, the upper end of the connector 613 is provided with a blocking part 612, the outer diameter of which is larger than the outer diameter of the connector. A gap exists between the blocking part 612 and the top of the body 611 along the axial direction of the vibration isolator 610, and the connector 501 is disposed within this gap. By providing the blocking part 612 at the upper end of the connector 613, the connector 501 is prevented from moving upwards and detaching from the connector 613, thus increasing the reliability of the connection between the connector 501 and the vibration isolator 610.

[0113] It should be noted that since the vibration isolator 610 is usually made of a relatively soft material such as rubber or silicone, by deforming the blocking part 612, the connecting part can be sleeved on the outer periphery of the connector 613, thereby realizing the mutual connection between the vibration isolator 610 and the connector 501.

[0114] like Figure 7 As shown, the inner diameter of the connector 613 is D2, and the outer diameter of the upper end of the sleeve 620 is D3. D1-D0≤0.5*(D2-D3) is used to create a gap between the connector 501 and the sleeve 620 to prevent them from contacting each other. This allows the vibration energy to be mainly absorbed and attenuated by the vibration isolator 610, preventing vibration from being transmitted downwards from the sleeve 620.

[0115] If D1-D0>0.5*(D2-D3), then the connector 501 will be in close contact with the sleeve 620 through the connector 613. The vibration carried by the connector 501 is easily transmitted to the sleeve 620 through the connector 613, thereby transmitting the vibration downward from the sleeve 620 and reducing the vibration isolation effect of the vibration isolator 610.

[0116] like Figures 7-9 As shown, the body 611 is provided with a first recess 601, which extends circumferentially along the vibration isolator 610. The first recess 601 is provided on the outer peripheral wall of the vibration isolator 610 so that when the body 611 is subjected to vibration, the body 611 protrudes towards the interior of the body 611, increasing the interference fit between the body 611 and the sleeve 620, thereby increasing the friction between the vibration isolator 610 and the sleeve 620, and thus increasing the vibration isolation effect of the vibration isolator 610.

[0117] like Figure 10 and Figure 11As shown, the sleeve 620 includes a base 621, which is located inside the body 611. The outer diameter D6 of the base 621 and the inner diameter D8 of the body 611 satisfy: D6≤D8, so that the body 611 and the base 621 are interference fit, increasing the friction between the base 621 and the body 611. This not only increases the support effect of the sleeve 620 on the vibration isolator 610, but also converts the mechanical energy of vibration into frictional heat energy, allowing the vibration isolator 610 to absorb part of the vibration and increase the vibration reduction effect of the vibration isolator 610.

[0118] Generally, the larger the interference fit, the greater the friction between the body 611 and the base 621, and the better the support effect of the base 621 on the body 611. However, it will also increase the stiffness of the vibration isolator 610 and reduce the vibration isolation performance of the vibration isolator 610.

[0119] Based on this, in this application, according to the vibration reduction performance requirements, annular grooves, protrusions and other structures can be provided on the inner wall of the body 611 to adjust the magnitude of the friction force between the body 611 and the base 621.

[0120] Specifically, such as Figure 7 and Figure 9 As shown, the body 611 is provided with a second recess 602, which extends circumferentially along the vibration isolator 610. The second recess 602 is provided on the inner peripheral wall of the vibration isolator 610 to reduce the contact area between the inner wall of the body 611 and the outer wall of the base 621, and to prevent the interference fit between the body 611 and the base 621 from being too large and thus reducing the vibration reduction effect of the body 611.

[0121] The second recess 602 and the first recess 601 are staggered along the axial direction of the vibration isolator 610 so that the body 611 deforms toward the inside of the body 611 when it is subjected to vibration, thereby increasing the amount of interference fit between the body 611 and the base 621.

[0122] The number M of the first recess 601 and the number N of the second recess 602 satisfy: M≤N-1, ensuring that the body 611 deforms inward under axial load, increasing the interference between the body 611 and the base 621. The greater the axial load on the vibration isolator 610, the greater the deformation of the body 611 and the greater the interference between the body 611 and the base 621. The large deformation of the body 611 increases the vibration reduction effect of the vibration isolator 610, while the increased interference between the body 611 and the base 621 increases the support effect of the sleeve 620 on the vibration isolator 610.

[0123] In some embodiments, the first recess 601 is an annular groove provided on the outer peripheral wall of the body 611; the second recess 602 is an annular groove provided on the inner peripheral wall of the body 611.

[0124] like Figure 9As shown, the radius R1 of the first recess 601 is greater than the radius R2 of the second recess 602, so that the body 611 deforms and protrudes towards the interior of the body 611 when it is vibrated, thereby increasing the interference fit between the body 611 and the base 621.

[0125] The central angle of the first recess 601 is less than or equal to 150°, and the central angle of the second recess 602 is greater than or equal to 180°, so that the body 611 deforms toward the inside of the body 611 when it is vibrated, thereby increasing the interference fit between the body 611 and the base 621.

[0126] like Figure 9 As shown, the body 611 is provided with a third recess 603, which is located at the bottom of the body 611. The third recess 603 allows the vibration isolator 610 to undergo local flexible deformation when subjected to the vibration of the compressor 500, thereby reducing the overall stiffness of the vibration isolator 610 and enabling the vibration isolator 610 to absorb and buffer high-frequency vibration energy more effectively.

[0127] In some embodiments, the third recess 603 is an annular groove provided at the bottom of the body 611, and the central angle of the third recess 603 is less than or equal to 180°, so that the opening of the third recess 603 is narrower, so that a local high elasticity area is formed at the bottom of the vibration isolator 610, which can more concentratedly undergo flexible deformation when subjected to the vibration of the compressor 500, thereby efficiently absorbing high-frequency vibration energy.

[0128] The diameter of the center line of the third recess 603 is D5, and the outer diameter of the base 621 is D8. D5≤D8 can prevent the bottom surface of the body 611 from being too thin and weakening the overall support, and prevent edge tearing or collapse due to vibration load.

[0129] The bottom of the body 611 has an opening that communicates with the interior of the body 611, so that the sleeve 620 is disposed inside the vibration isolation member 610 through the opening at the bottom of the body 611.

[0130] The sleeve 620 has a through cavity that extends along the axial direction of the sleeve 620, so that the vibrations received by the sleeve 620 are concentrated on the peripheral wall of the sleeve 620, and the peripheral wall of the sleeve 620 is in contact with the peripheral wall of the vibration isolator 610, so that the vibration isolator 610 can absorb or isolate the vibrations received by the sleeve 620.

[0131] The inner diameter of the bottom opening of the main body 611 is D7, and the inner diameter of the bottom of the sleeve 620 is D9, where D7 ≤ D9. This ensures the mating area between the bottom of the base 621 and the bottom of the main body 611, allowing the bottom surface of the sleeve 620 to fully contact the bottom surface of the main body 611. This enables the main body 611 to isolate the vibration transmitted by the sleeve 620, increasing the vibration isolation effect of the main body 611. It also prevents the base 621 from detaching from the bottom opening of the main body 611 and directly contacting the base plate 140, thus preventing the vibration received by the sleeve 620 from being transmitted to the housing 100.

[0132] If D7>D9, the base 621 can easily leave the interior of the body 611 through the opening at the bottom of the body 611, and the base 621 can easily come into direct contact with the base plate 140. The vibration generated by the compressor 500 can easily be transmitted from the sleeve 620 to the base plate 140, reducing the vibration isolation effect of the vibration isolator 610.

[0133] like Figure 10 and Figure 11 As shown, the sleeve 620 includes an end 624, which is disposed inside the connector 613 and at the top of the intermediate section 623. The outer diameter of the end 624 is D3, and there is a radial gap between the outer wall of the end 624 and the inner wall of the connector 613 to avoid direct contact between the end 624 and the connector 613.

[0134] The sleeve 620 includes an intermediate section 623, which is located on the top of the base 621 and is used to connect the base 621 and the end 624. The support part 625 is located on the outer peripheral wall of the intermediate section 623, and the intermediate section 623 is also used to support the vibration isolation member 610.

[0135] The sleeve 620 includes a transition section 622, which is located at the connection between the intermediate section 623 and the base 621. The outer diameter of the transition section 622 is smaller than the outer diameter of the base 621 but larger than the outer diameter of the end 624. The transition section 622 and the base 621 together form a step, which is located below the support portion 625. When the sleeve 620 is located inside the vibration isolator 610, the step is located below the contact portion 614. By having the transition section 622 and the base 621 together form a step, the top of the base 621 can limit the vibration isolator 610, preventing the compressor 500 from undergoing large displacement and damaging the pipeline.

[0136] When the compressor 500 is running or the outdoor unit of the air conditioner is suddenly dropped during transportation, the vibration isolation component 610 is subjected to the vibration generated by the compressor 500. The vibration isolation component 610 is subjected to a downward force and moves downward. The top wall of the body 611 comes into contact with the top of the base 621. The top of the base 621 provides support and limits the body 611, preventing the body 611 from continuing to deform downward, thereby limiting the vibration isolation component 610.

[0137] The height of the transition section 622 is H1, that is, the height of the step is H1. When the air conditioner outdoor unit falls, the maximum allowable displacement S1 of the compressor 500. H1 < S1 to avoid adverse consequences caused by excessive displacement of the compressor 500.

[0138] The maximum vibration displacement S2 of the air conditioner outdoor unit during normal operation. S2 < H1 to ensure that the body 611 does not contact the shoulder during normal operation, avoid the vibration being transmitted downward from the sleeve 620, and ensure the vibration isolation amount.

[0139] It should be noted that when the air conditioner outdoor unit falls, the deformation of the contact part 614 can reduce the impact speed, reduce the transient stress amplitude, and reduce the pipeline damage.

[0140] The outer diameter D1 of the connector 613 and the outer diameter D4 of the transition section 622 satisfy the relationship: D1 ≥ D4 to reduce the direct downward transmission of axial vibration through the sleeve 620.

[0141] The working principle of the vibration isolation component 600 in the above air conditioner outdoor unit is as follows: When the compressor 500 generates vibration, the vibration is transmitted to the vibration isolation member 610 through the connecting member 501. The vibration isolation member 610 absorbs the high-frequency vibration energy through elastic deformation. Since the contact part 614 and the support part 625 are closely配合, the vibration is decomposed into an axial component force and a radial component force. The axial component force causes the vibration isolation member 610 to deform downward. When the vibration isolation member 610 deforms downward, the pressure exerted by the contact part 614 on the support part 625 increases, the friction force between the contact part 614 and the support part 625 increases, and the friction force between the body 611 and the base 621 also increases; the radial component force causes the vibration isolation member 610 to deform towards the inside of the body 611, increasing the interference fit amount between the body 611 and the base 621, increasing the friction force between the body 611 and the base 621, and the frictional energy consumes most of the mechanical vibration energy in the vertical direction, reducing the vibration transmitted by the vibration isolation member 610 to the bottom plate 140.

[0142] Since the sleeve 620 forms a support for the vibration isolation member 610 through the support part 625, it avoids the large deformation of the vibration isolation member 610, increases the rigidity of the vibration isolation member 610, thereby increasing the firmness of the installation of the compressor 500 and avoiding the shaking of the compressor 500.
