Description

Technical Field

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

[0002] Many central air conditioning outdoor units are installed on the roof of buildings. The feet of the outdoor units are connected to the mounting base (cement base) on the roof with connecting bolts. The noise generated when the outdoor unit is working will be transmitted to the user through the mounting base and the roof.

[0003] To address this issue, related technologies employ laying a rubber layer on the mounting base. However, even with the rubber layer, the outdoor unit's noise still transmits outwards through the connecting bolts, which are rigid. Summary of the Invention

[0004] This application provides an outdoor unit for an air conditioner, which has the advantage of good vibration reduction effect.

[0005] In one aspect of this application, an outdoor unit for an air conditioner includes: a frame assembly; a base connected to the bottom end of the frame assembly, the base having a first mounting portion; and a first rubber pad connected to the bottom end of the base corresponding to the first mounting portion, the first rubber pad having a first through hole for fasteners to pass through.

[0006] The first rubber pad includes: a first vibration isolation part located on the bottom side of the base; and a second vibration isolation part connected to the first vibration isolation part and passing through the first mounting part, wherein the second vibration isolation part has an exposed part protruding from the first mounting part, the exposed part being located between the first mounting part and the nut in the fastener or between the first mounting part and the bolt head in the fastener.

[0007] In this application, the first vibration-damping portion of the first rubber pad separates the lower end of the foot from the mounting base and the lower part of the fastener, preventing contact between the foot and the mounting base, and between the foot and the lower part of the fastener. The second vibration-damping portion separates the foot from the middle part of the fastener. The exposed portion separates the upper end of the foot from the upper part of the fastener, preventing contact between the foot and the upper part of the fastener. Thus, the first rubber pad completely isolates the foot from the mounting base and the foot from the fastener. Utilizing the vibration-damping effect of the first rubber pad, the vibration transmission from the foot to the mounting base is effectively reduced, significantly reducing vibration noise and improving the user experience.

[0008] In some embodiments, the outdoor unit of the air conditioner further includes: a rubber ring having a second through portion thereon; and an exposed portion located within the second through portion.

[0009] In this application, the outer diameter of the rubber ring is not limited and can be set to be relatively large, thereby increasing the damping area and improving the damping effect.

[0010] In another aspect of the present application, an air conditioner outdoor unit comprises: a frame assembly; a foot connected to a bottom end of the frame assembly, the foot being provided with a first mounting portion; and a first rubber pad connected to the bottom end of the foot corresponding to the first mounting portion, the first rubber pad being provided with a first through hole for a fastener to pass through;

[0011] The first rubber pad comprises: a first vibration isolation portion located on a bottom side of the foot; and a second vibration isolation portion connected to the first vibration isolation portion and passing through the first mounting portion.

[0012] The air conditioner outdoor unit further comprises: a rubber ring provided on a side of the first mounting portion opposite to the first vibration isolation portion, the rubber ring being located between the first mounting portion and a nut of the fastener or between the first mounting portion and a head of a bolt of the fastener.

[0013] In the present application, the first vibration isolation portion of the first rubber pad can separate the lower end of the foot from the mounting base and the lower part of the fastener, avoiding the contact between the foot and the mounting base and between the foot and the lower part of the fastener. The second vibration isolation portion can separate the foot from the middle part of the fastener. The rubber ring can separate the upper end of the foot from the upper part of the fastener, avoiding the contact between the foot and the upper part of the fastener. Thus, the foot can be completely separated from the mounting base and the fastener by the first rubber pad and the rubber ring. By using the isolation and damping effect of the first rubber pad and the rubber ring, the vibration transmission of the foot to the mounting base is effectively reduced, the vibration noise is greatly reduced, and the user experience is improved.

[0014] In some embodiments, the first rubber pad is provided with a break portion; in the axial direction of the first through portion, the break portion penetrates the first rubber pad; and in the direction perpendicular to the axial direction of the first through portion, the break portion extends from the outer side of the first rubber pad to the inner side of the first rubber pad.

[0015] In the present application, by providing the break portion on the first rubber pad, the first rubber pad can be selectively installed on the fastener from the side, facilitating the installation of the first rubber pad.

[0016] In some embodiments, the air conditioner outdoor unit further comprises: at least one second rubber pad connected to the bottom end of the foot, the second rubber pad being arranged in space with the first rubber pad.

[0017] In the present application, the second rubber pad is connected to the foot, which can increase the damping area between the foot and the mounting base and improve the damping effect.

[0018] In some embodiments, the second rubber pad comprises a third vibration isolation portion and a fourth vibration isolation portion connected to each other, the fourth vibration isolation portion being located on a side of the third vibration isolation portion away from the foot.

[0019] The outdoor unit of the air conditioner further comprises a fixing member abutting against the bottom surface of the third vibration isolation part and connected with the bottom foot, and the fixing member is provided with an opening part; and a part of the fourth vibration isolation part passes through the fixing member from the opening part.

[0020] In the present application, the second rubber pad is connected with the bottom foot through the fixing member. In the case that the first rubber pad is forgotten or lost, the second rubber pad can be removed and installed at the coupling bolt to be used as the first rubber pad.

[0021] In some embodiments, the fixing member is provided with a containing groove containing the third vibration isolation part, and the edge of the containing groove is provided with a turned edge part abutting against the bottom foot.

[0022] In some embodiments, the second rubber pad has the same structure as the first rubber pad; the bottom foot is provided with a second mounting part; and the second vibration isolation part of the second rubber pad is arranged in the second mounting part.

[0023] In the present application, the second rubber pad has the same structure as the first rubber pad, which can increase the vibration reduction area between the bottom foot and the mounting base and improve the vibration reduction effect, and the second rubber pad can be used as the first rubber pad to solve the problem of forgetting or losing the first rubber pad.

[0024] In some embodiments, the opposite two ends of the bottom foot are connected with the first rubber pad, and the second rubber pad is arranged between the two first rubber pads.

[0025] In some embodiments, the bottom foot comprises a first connecting wall provided with a first mounting part, a second connecting wall arranged in a spaced manner with the first connecting wall and connected with the frame assembly, and a third connecting wall connected between the first connecting wall and the second connecting wall.

[0026] In the present application, the first connecting wall, the second connecting wall and the third connecting wall form a "U" shaped groove, and the upper end of the fastener at the first mounting part is located in the "U" shaped groove, which avoids the problem that the fastener is completely exposed and is easy to be hit by personnel.

[0039] 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.

[0040] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] Reference Figure 1 Many central air conditioning outdoor units are installed on rooftops, with fasteners such as connecting bolts 61 pre-installed on the rooftop mounting base 60 (cement base).

[0044] In the outdoor unit of the air conditioner, the bottom end of the frame assembly 10 is connected to a foot 20. During installation, first align the hole on the foot 20 with the connecting bolt 61, then place the entire outdoor unit on the mounting base 60, and finally install the washer 63 on the connecting bolt 61 and tighten the nut 62 to firmly connect the foot 20 to the mounting base 60, thereby achieving a stable installation of the outdoor unit of the air conditioner.

[0045] The vibration and noise generated by the compressor and fan in the outdoor unit will be transmitted to the user. Specifically, the transmission route of vibration and noise is: outdoor unit frame → base 20 → mounting base 60 → roof → air → user. In order to solve this problem, the existing technology will lay a rubber layer 70 on the roof in advance. However, since the need for connecting bolts 61 to fix the outdoor unit at the installation site is not considered in advance, and the connecting bolts 61 are rigid bodies, the vibration and noise transmission route of outdoor unit frame → base 20 → connecting bolts 61 → mounting base 60 → roof → air → user still exists, and the vibration transmission problem is not completely solved.

[0046] To address the above technical problems, the inventive concept of this application is proposed: by improving the structure of the rubber pad, the rubber pad can completely separate the foot 20 from the mounting base 60 (including the connecting bolt 61), thereby effectively reducing vibration and noise.

[0047] The embodiments of this application will be described in detail below with reference to the accompanying drawings:

[0048] Reference Figure 2 An outdoor unit for an air conditioner according to an embodiment of this application includes a frame assembly 10.

[0049] The frame assembly 10 includes an outdoor unit frame 11. The outdoor unit frame 11 may be in the shape of a cuboid box, forming the general appearance of the outdoor unit of the air conditioner. The outdoor unit frame 11 may be composed of multiple sheet metal pieces connected together.

[0050] The frame assembly 10 also includes an outdoor fan (not shown), and components located on the refrigeration cycle, such as an outdoor heat exchanger and a compressor (not shown); these components are all housed within the outdoor unit frame 11. Since the internal structure of the frame assembly 10 is applicable to all types of air conditioning outdoor units, this application will not further describe the internal structure of the frame assembly 10.

[0051] The outdoor unit of the air conditioner includes a base 20. The base 20 is connected to the bottom end of the frame assembly 10 to support the frame assembly 10 and to achieve fixed installation of the outdoor unit of the air conditioner.

[0052] There may be two base feet 20. In this embodiment, the base feet 20 are elongated, and the two base feet 20 are respectively connected to opposite ends of the bottom surface of the frame assembly 10.

[0053] In this application, the length extension direction of the base 20 is referred to as the left-right direction, the arrangement direction of the two bases 20 is referred to as the front-back direction, and the height direction of the frame assembly 10 is referred to as the up-down direction.

[0054] The base 20 has at least two holes forming first mounting portions 201 for connection with connecting bolts 61 on the mounting base 60. The two first mounting portions 201 are located at opposite ends of the base 20 in the left and right directions, respectively.

[0055] Reference Figures 3 to 6 The outdoor unit of the air conditioner includes a first rubber pad 30. The first rubber pad 30 is connected to the base 20 corresponding to the first mounting part 201, and is used to separate the base 20 from the mounting base 60, and to separate the base 20 from the connecting bolt 61, so as to isolate the vibration transmission from the base 20 to the mounting base 60.

[0056] The first rubber pad 30 includes a first vibration isolation portion 31. The first vibration isolation portion 31 is located at the bottom end of the base 20. In the assembled state, the first vibration isolation portion 31 is located between the base 20 and the mounting base 60.

[0057] The first rubber pad 30 includes a second vibration isolation portion 32. The second vibration isolation portion 32 is connected to the first vibration isolation portion 31 and passes through the first mounting portion 201.

[0058] The end of the second vibration isolation portion 32 that is away from the first vibration isolation portion 31 is exposed in the first mounting portion 201. In this application, the portion of the second vibration isolation portion 32 that is exposed in the first mounting portion 201 is referred to as the exposed portion 321.

[0059] In the radial direction of the first mounting portion 201, the second vibration isolation portion 32 is located between the side wall of the first mounting portion 201 and the connecting bolt 61, which can prevent the base 20 from radially contacting the connecting bolt 61.

[0060] If the connecting bolt 61 is pre-installed on the mounting base 60, with the tail end of the connecting bolt 61 being the upper end, and the nut 62 that matches the bolt in the fastener is installed from the upper end, then in the axial direction of the first mounting part 201, the exposed part 321 is located between the nut 62 and the foot 20, which can separate the nut 62 from the foot 20.

[0061] If the connecting bolt 61 is installed from the base 20, that is, the connecting bolt 61 is sequentially passed through the base 20 and the mounting base 60, then in the axial direction of the first mounting part 201, the exposed part 321 is located between the bolt head of the connecting bolt 61 and the base 20, which can separate the bolt head from the base 20.

[0062] Washer 63 can be used at nut 62. Connecting bolt 61, nut 62, etc. are matching fasteners.

[0063] As described above, in this application, the first rubber pad 30 includes a first vibration isolation portion 31 located between the foot 20 and the mounting base 60, and a second vibration isolation portion 32 passing through the first mounting portion 201. The second vibration isolation portion 32 has an exposed portion 321 exposed to the first mounting portion 201. The first vibration isolation portion 31 can separate the lower end of the foot 20 from the mounting base 60 and the lower part of the fastener (the part of the connecting bolt 61 located between the foot 20 and the mounting base 60), thereby avoiding contact between the foot 20 and the mounting base 60, and between the foot 20 and the lower part of the fastener.

[0064] The second vibration isolation part 31 can separate the foot 20 from the middle part of the fastener (the part of the connecting bolt 61 located on the first mounting part 201). The exposed part 321 can separate the upper end of the foot 20 from the upper part of the fastener (the part of the connecting bolt 61 located on the upper side of the foot 20 and the nut 62), thus preventing the foot 20 from contacting the upper part of the fastener.

[0065] Therefore, the first rubber pad 30 can completely isolate the foot 20 from the mounting base 60 and the fasteners. Utilizing the isolation and vibration damping effect of the first rubber pad 30, the vibration transmission from the foot 20 to the mounting base 60 is effectively reduced, significantly decreasing vibration noise and improving the user experience.

[0066] For example, the tail of the connecting bolt 61 is located at the upper end. During assembly, the outdoor unit is aligned with the connecting bolt 61 and placed on the mounting base 60. Then, the nut 62 is installed from the upper end of the connecting bolt 61, thereby firmly connecting the foot 20 to the mounting base 60.

[0067] The base 20 and the mounting base 60, as well as the base 20 and the fasteners, are separated by the first rubber pad 30. The vibration transmission route of the outdoor unit of the air conditioner becomes: outdoor unit frame 11 → base 20 → first rubber pad 31 → connecting bolt 61 → mounting base 60 → rooftop → user. Due to the isolation and vibration damping effect of the first rubber pad 31 along the transmission path, the vibration noise transmitted from the outdoor unit of the air conditioner is effectively reduced.

[0068] According to an embodiment of this application, the first rubber pad 30 has a first through portion 33 in the middle, which passes through the first vibration isolation portion 31 and the second vibration isolation portion 32. The connecting bolt 61 passes through the first through portion 33.

[0069] The first vibration isolation part 31 does not protrude beyond the outer contour of the base 20 in the left-right and front-back directions, thus avoiding waste of material in the first vibration isolation part 31. If the first vibration isolation part 31 protrudes beyond the base 20 in the front-back direction, the part of the first vibration isolation part 31 protruding beyond the base 20 will not achieve the purpose of vibration reduction because it does not contact the base 20, resulting in material waste.

[0070] It should be noted that "protrusion" here refers to the projection on the bottom surface of the base 20, and part of the first vibration isolation part 31 is located outside the outer contour of the base 20.

[0071] The first vibration isolation part 31 can be in the shape of a rectangular block. Since the bottom surface of the base 20 is rectangular, the first vibration isolation part 31 is set in the shape of a rectangular block. Without wasting materials, the contact area between the first vibration isolation part 31 and the base 20 can be maximized, thereby achieving the best vibration isolation effect.

[0072] The second vibration isolation part 32 can be adapted to the shape of the first mounting part 201 and is in the form of a ring.

[0073] In some embodiments, see specific references Figure 4 The first rubber pad 30 is provided with a break portion 34 so that the first rubber pad 30 can be radially installed onto the connecting bolt 61 from the break portion 34.

[0074] The break portion 34 extends through the first rubber pad 30 in the vertical direction. In the radial direction of the first through portion 33, the break portion 34 extends from the outer side of the first rubber pad 30 to the inner side of the first rubber pad 30.

[0075] The radial break width of the break portion 34 is less than the outer diameter of the connecting bolt 61.

[0076] Because the outdoor unit is very heavy, it is difficult to lift once it is lowered from the crane. If the first rubber pad 30 is axially fitted onto the connecting bolt 61 before lowering the outdoor unit, it will increase the time required to lift the outdoor unit, thus increasing the risk of it falling. Moreover, since the outdoor unit is a key focus, it is easy to forget to install the first rubber pad 30 before lowering it on the installation site. Therefore, this application provides a break portion 34 on the first rubber pad 30, allowing for side installation.

[0077] Reference Figures 7 to 9 When installing the outdoor unit of the air conditioner, first align the first mounting part 201 of the base 20 with the connecting bolt 61, then place the outdoor unit on the mounting base 60, press down one end of the outdoor unit in the left and right directions, so that the outdoor unit is slightly tilted and the opposite end of the outdoor unit is raised. Then wrap it around the connecting bolt 61 through the broken part 34 on the first rubber pad 30. After continuing to flatten the outdoor unit, let the second vibration isolation part 31 of the first rubber pad 30 pass through the first mounting part 201 on the base 20.

[0078] In some embodiments, at the installation site, to facilitate the insertion of the second vibration isolation part 32 into the first mounting part 201, the outer diameter of the second vibration isolation part 32 is not greater than the inner diameter of the first mounting part 201. If the outer diameter of the second vibration isolation part 32 exceeds the inner diameter of the first mounting part 201, then the second vibration isolation part 32 needs to be deformed to be installed into the first mounting part 201, which will reduce the installation efficiency at the site.

[0079] Because the outer diameter of the second vibration isolation part 32 is small, the contact area between the washer 63 or nut 62 and the second vibration isolation part 32 is relatively small, which will reduce the vibration reduction effect at the second vibration isolation part 32.

[0080] Therefore, in some embodiments, reference is made to Figure 6 The outdoor unit of the air conditioner may include a rubber ring 40. The rubber ring 40 is fitted onto the connecting bolt 61 and located on the upper side of the first mounting part 201. The outer diameter of the rubber ring 40 is not limited and can be set to be relatively large, thereby increasing the vibration damping area and improving the vibration damping effect.

[0081] In this embodiment, the first rubber pad 30 still has an exposed portion 321. The rubber ring 40 is fitted over the exposed portion 321.

[0082] The upper surface of the rubber ring 40 is flush with the upper surface of the exposed portion 321. The rubber ring 40 increases the contact area between the gasket 63 and the rubber. This flush alignment is within the allowable design tolerance.

[0083] The rubber ring 40 may be cylindrical. The inner ring of the rubber ring 40 is a second through-hole 41 that passes through the rubber ring 40. The exposed portion 321 of the first rubber pad 30 is located within the second through-hole 41.

[0084] The outer diameter of the rubber ring 40 is not less than the outer diameter of the gasket 63, which ensures that a portion of the lower surface of the gasket 63 contacts the exposed portion 321 and the other portion contacts the rubber ring 40.

[0085] Or, refer to Figure 10 and Figure 11 The second through portion 41 of the rubber ring 40 is stepped. The second through portion 41 includes a receiving hole 411 and a through hole 412, the inner diameter of the receiving hole 411 being larger than the inner diameter of the through hole 412. The exposed portion 321 is located inside the receiving hole 411, and a connecting bolt 61 is inserted through the through hole 412.

[0086] The gasket 63 contacts only the upper end face of the rubber ring 40, and does not contact the exposed part 321.

[0087] The rubber ring 40 is fitted outside the second vibration isolation part 32, which can tighten the second vibration isolation part 32 and prevent the bottom foot 20 from touching the connecting bolt 61 from the break part 34 during vibration.

[0088] In some embodiments, in the first rubber pad 30, the second vibration isolation portion 32 is completely located within the first mounting portion 201, with no exposed portion 321. In this embodiment, the second through portion 41 of the rubber ring 40 is adapted to the connecting bolt 61, that is, the connecting bolt 61 passes through the second vibration isolation portion 32 and the rubber ring 40. The lower surface of the gasket 63 only contacts the rubber ring 40.

[0089] As described above, in this application, the first rubber pad 30 includes a first vibration isolation portion 31 located between the foot 20 and the mounting base 60, and a second vibration isolation portion 32 passing through the first mounting portion 201; the first vibration isolation portion 31 can separate the lower end of the foot 20 from the mounting base 60 and the bottom of the fastener, avoiding direct contact between the foot 20 and the mounting base 60, and between the foot 20 and the bottom of the fastener.

[0090] The second vibration isolation part 31 can separate the base foot 20 from the middle of the fastener, thus preventing the base foot 20 from contacting the middle of the fastener.

[0091] The rubber ring 40 is located on the upper side of the first mounting part 201, which can separate the foot 20 from the upper part of the fastener and prevent the foot 20 from contacting the upper part of the fastener.

[0092] Therefore, the first rubber pad 30 and the rubber ring 40 can completely isolate the foot 20 from the mounting base 60 and the fasteners. Utilizing the isolation and vibration damping effect of the first rubber pad 30 and the rubber ring 40, the vibration transmission from the foot 20 to the mounting base 60 is effectively reduced, significantly decreasing vibration noise and improving the user experience.

[0093] In some embodiments, continue to refer to Figure 5 and Figure 6 The outdoor unit of the air conditioner may include a second rubber pad 50. The second rubber pad 50 is attached to the base 20 and located between the two first rubber pads 30. There is no connecting bolt 61 at the second rubber pad 50.

[0094] The second rubber pad 50 is located between the foot 20 and the mounting base 60, which can increase the vibration damping area between the foot 20 and the mounting base 60, and further improve the vibration damping effect on the outdoor unit of the air conditioner.

[0095] According to an embodiment of this application, the second rubber pad 50 is connected to the foot 20 via a fastener 80.

[0096] Combination Figure 4 The second rubber pad 50 includes a third vibration isolation part 51. The upper end surface of the third vibration isolation part 51 abuts against the bottom surface of the base 20.

[0097] The second rubber pad 50 includes a fourth vibration isolation portion 52 connected to the third vibration isolation portion 51. The fourth vibration isolation portion 52 extends outward from the lower end of the third vibration isolation portion 52.

[0098] The fixing member 80 abuts against the third vibration isolation part 51 from the lower end upward, and the fixing member 80 is connected to the foot 20, thereby realizing the connection of the second rubber pad 50 on the foot 20.

[0099] The fourth vibration isolation part 52 protrudes from the lower end of the fixing member 80. The lower end face of the fourth vibration isolation part 52 is in contact with the mounting base 60.

[0100] Since the fourth vibration isolation part 52 separates the fixing member 80 and the mounting base 60, rigid contact between the fixing member 80 and the mounting base 60 is avoided.

[0101] According to an embodiment of this application, on the projection of the bottom surface of the third vibration isolation portion 51, the third vibration isolation portion 51 has a portion that does not overlap with the fourth vibration isolation portion 52. This portion is also the portion that protrudes from the side of the fourth vibration isolation portion 52. In this application, this portion is referred to as the extension portion 511.

[0102] The lower end of the fastener 80 abuts against the extension 511, and the upper end of the fastener 80 abuts against the base 20.

[0105] The second wall 82 has at least two opposite parts, and each of the two second walls 82 is provided with an outwardly extending flange 83.

[0106] There may be four second walls 82, located in four directions. At least two opposite second walls 82 are provided with flanges 83.

[0107] The four second walls 82 and the first wall 81 form a receiving groove 84. The third vibration isolation part 51 is located inside the receiving groove 84.

[0108] The fastener 80 is a sheet metal part. The second wall 82 is formed by bending the edge portion of the first wall 81 upwards. The flange portion 83 can be formed by bending the upper edge portion of the second wall 82 outwards laterally.

[0109] In some embodiments, the second rubber pad 50 may have the same structure as the first rubber pad 30. The third vibration isolation portion 51 and the fourth vibration isolation portion 52 of the second rubber pad 50 are equivalent to the first vibration isolation portion 31 of the first rubber pad 30. Similarly, the first vibration isolation portion 31 of the first rubber pad 30 may include the third vibration isolation portion 51 and the fourth vibration isolation portion 52.

[0110] The base 20 is provided with a second mounting part 202 of the same size as the first mounting part 201. The upper end of the third vibration isolation part 51 is connected to the second vibration isolation part 32. The second vibration isolation part 32 of the second rubber pad 50 passes through the second mounting part 202.

[0111] The second rubber pad 50 is connected to the base 20 via the fastener 80. In the event that the first rubber pad 30 is forgotten or lost, the second rubber pad 50 can be removed and installed at the connecting bolt 61 for use as the first rubber pad 30.

[0112] According to embodiments of this application, at least two second rubber pads 50 may be provided, with the second rubber pads 50 disposed between two first rubber pads 30. On one hand, the second rubber pads 50 can increase the vibration damping area between the base 20 and the mounting base 60, thereby improving the vibration damping effect; on the other hand, the second rubber pads 50 can be used as first rubber pads 30 to address the situation where the first rubber pads 30 are forgotten or lost.

[0113] In some embodiments, refer to Figure 13 The base 20 includes a first connecting wall 21 at the lower end, a second connecting wall 22 at the upper end, and a third connecting wall 23 connecting the first connecting wall 21 and the second connecting wall 22.

[0114] The second connecting wall 22 is used to connect to the outdoor unit frame 11. The second connecting wall 22 abuts against the bottom surface of the outdoor unit frame 11, and the two can be connected by fasteners such as screws.

[0115] The first connecting wall 21 is used to connect with the mounting base 60. The first connecting wall 21 abuts against the mounting base 60, and the two are connected by connecting bolts 61.

[0116] The longitudinal section of the base 20 can be U-shaped. The open end of the U-shape faces away from the other base 20, that is, the opening of the front base 20 faces forward, and the opening of the rear base 20 faces backward. This facilitates the installation of the nut at the connecting bolt 61 from the open side.

[0117] In some embodiments, the foot 20 may include a fourth connecting wall 24 disposed at its left and right ends. The fourth connecting wall 24 is connected to the end of the third connecting wall 23 and is located approximately between the first connecting wall 21 and the second connecting wall 23. This can increase the structural strength of the foot 20 and prevent the weight of the frame assembly 10 from acting on the second connecting wall 23 and causing the second connecting wall 23 to deform.

[0118] The fourth connecting wall 24 may be L-shaped. The first connecting wall 24 includes a first side wall 241 and a second side wall 242 that are connected to each other.

[0120] The first mounting part 201 is disposed on the first connecting wall 21. In the left-right direction, the first mounting part 201 is located between the two second side walls 242 at the left and right ends. In this way, since the first mounting part 201 is not obstructed by the fourth connecting wall 24, it is convenient for operators to perform installation operations on the first mounting part 201, such as installing rubber pads on the first mounting part 201 or tightening nuts on the connecting bolts 61.

[0121] According to an embodiment of this application, the outer edge of the second connecting wall 22 is provided with an upwardly extending stop 221. The stop 221 can abut against the side of the outdoor unit frame 11 to limit the distance between the foot 20 and the outdoor unit frame 11, thereby improving the efficiency of installing the foot 20 onto the outdoor unit frame 11.

[0122] The aforementioned outer end refers to the end of the second connecting wall 22 closest to its opening. For the front foot 20, the outer end is located at the front end of the second connecting wall 22. For the rear foot 20, the outer end is located at the rear end of the second connecting wall 22.

[0123] The base 20 can be machined from sheet metal. The first connecting wall 21 is formed by bending the lower part of the third connecting wall 23. The second connecting wall 22 is formed by bending the upper part of the third connecting wall 23. The fourth connecting part 24 is formed by bending the left and right ends of the third connecting wall 23. The second side wall 242 of the fourth connecting wall 24 is formed by bending the first side wall 241.

[0124] In other embodiments, refer to Figure 1 The base 20 may include a base body 25. The base body 25 may be block-shaped, and its upper end is connected to the outdoor unit frame 11. The left and right ends of the base body 25 extend outward to form connecting portions 26. A first mounting portion 201 is provided on the connecting portion 26.

[0125] In other embodiments, there may be four feet 20, which are respectively located at the four corners of the bottom surface of the frame assembly 10. A first mounting portion 201 is provided on the bottom wall of the foot 20 for mounting the first rubber pad 30.

[0126] The base 20 can also be formed by extending downwards from the four corners of the outdoor unit frame 11. It should be noted that this application does not limit the structural form of the base 20.
