Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner outdoor unit. BACKGROUND

[0002] The compressor is the main operating equipment in the air conditioner, and is also the main noise and vibration source of the air conditioner. When the air conditioner is running, the vibration generated by the compressor is transmitted to the external sheet metal through sheet metal, pipeline and other components. Since the sheet metal of the outdoor unit in the industry is currently a large-area thin plate structure, it has the characteristics of small stiffness and fast response, and is prone to forced vibration when the compressor is vibrating, which amplifies the noise and radiates outward, seriously affecting the user's experience. CONTENT OF THE UTILITY MODEL

[0003] The present application provides an air conditioner outdoor unit, which can effectively reduce the transmission of compressor vibration and reduce noise.

[0004] In one aspect of the present application, an air conditioner outdoor unit comprises: a shell having a bottom plate; a compressor arranged in the shell, the compressor comprising: a compressor body; a support plate connected to the bottom end of the compressor body; a first rubber pad arranged through the support plate, the bottom of the first rubber pad being provided with an upwardly recessed accommodating cavity, and the top of the first rubber pad having an exposed portion located on the upper side of the support plate; a second rubber pad arranged through the bottom plate, the upper portion of the second rubber pad being inserted into the accommodating cavity, and the bottom of the second rubber pad having a first limiting portion located on the lower side of the bottom plate; and a fastener arranged through the second rubber pad and the first rubber pad, for tightly connecting the support plate and the bottom plate.

[0005] In this technical solution, the first rubber pad is arranged through the support plate, so that the circumferential side of the support plate and the fastener is completely separated by the first rubber pad; the second rubber pad is arranged through the bottom plate, so that the circumferential side of the bottom plate and the fastener is completely separated by the second rubber pad. In addition, the exposed portion of the first rubber pad is located on the upper side of the support plate, so that the upper surface of the support plate and the fastener are separated by the first rubber pad; and the first limiting portion of the second rubber pad is located on the lower side of the bottom plate, so that the lower surface of the bottom plate and the fastener are separated by the second rubber pad. This technical solution realizes complete soft connection between the support plate and the fastener, and between the bottom plate and the fastener, so that the vibration of the compressor cannot be transmitted to the bottom plate through the fastener, greatly improving the vibration and noise problem of the air conditioner outdoor unit.

[0006] In addition, the insertion form of the first rubber pad and the second rubber pad makes the installation relatively simple.

[0007] In another aspect of the present application, an air conditioner outdoor unit is provided, wherein the upper portion of the first rubber pad is clamped to the support plate, and the middle portion of the second rubber pad is clamped to the bottom plate.

[0013] In some embodiments, the support plate is provided with a first mounting hole; the first rubber pad comprises: a first connecting part connected to the lower end of the exposed part and penetrating through the first mounting hole; and a supporting part connected to the lower end of the first connecting part, the supporting part and the exposed part being clamped on the upper and lower sides of the support plate.

[0014] In the technical scheme, the exposed part and the supporting part of the first rubber pad are clamped on the upper and lower sides of the support plate, wherein the exposed part limits the downward movement of the first rubber pad, so that the first rubber pad is prevented from falling off the support plate downwardly, the supporting part limits the upward movement of the first rubber pad, so that the first rubber pad is prevented from falling off the support plate upwardly, and the reliable connection of the first rubber pad on the support plate is ensured.

[0015] In some embodiments, the second rubber pad further comprises: a plug-in part connected to the upper end of the second limiting part and plugged into the accommodating cavity, the outer diameter of the plug-in part is smaller than the hole diameter of the second mounting hole, and the distance H1 from the top end of the plug-in part to the bottom end of the second limiting part and the height H2 of the supporting part satisfy: H1≥(1 / 3)H2.

[0016] In the technical scheme, H1 is in the range, so that H1 can be ensured not to be too small, and thus the upper part of the second rubber pad can be prevented from being separated from the accommodating cavity of the first rubber pad when the compressor vibrates.

DETAILED DESCRIPTION

[0037] For the purpose of making the objects and implementation of the present application more clear, the present application exemplary implementation will be described clearly and completely below in combination with the drawings of the present application exemplary embodiments. Obviously, the described exemplary embodiments are only some of the embodiments of the present application, but not all of the embodiments.

[0038] In the description of the present application, it needs to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0039] The terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features referred to. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, "a plurality of" means two or more, unless otherwise specified and limited.

[0040] In the description of the present application, it needs to be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been adjusted and heat exchanged.

[0042] The compressor compresses the refrigerant gas in a low-temperature and low-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0043] The expansion valve expands the liquid-phase refrigerant in a high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0044] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger, the indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0045] The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner serves as a heater in a heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner serves as a cooler in a cooling mode.

[0046] The outdoor unit and the indoor unit of the air conditioner are two-body structures, and the outdoor unit is also referred to as an air conditioner outdoor unit, and the indoor unit is also referred to as an air conditioner indoor unit.

[0047] Referring to Figure 1 and Figure 2 , the air conditioner outdoor unit according to the embodiment of the present application includes a housing 10.

[0048] The housing 10 has a rectangular parallelepiped shape and constitutes a general appearance of the air conditioner outdoor unit. The housing 10 can be formed by connecting a plurality of sheet metals. The sheet metals can be connected by fasteners such as screws or can be welded.

[0049] The housing 10 includes a bottom plate 13 defining a bottom configuration, a top plate 14 defining a top configuration, and a side plate 15 connected between the bottom plate 13 and the top plate 14.

[0050] The housing 10 includes an air inlet 11 through which outdoor air is introduced, and an air outlet 12 through which air introduced through the air inlet 11 is discharged to an outdoor space after heat exchange.

[0051] In some embodiments, a rear side portion of the housing 10 is open to form a part of the air inlet 11. A left side surface of the housing 10 can be provided with a grating plate, and holes of the grating plate form another part of the air inlet 11.

[0052] A front side surface of the housing 10 is provided with an air outlet grating, and holes of the air outlet grating form the air outlet 12.

[0053] Air introduced through the air inlets 11 of the rear side and the left side is discharged from the air outlet 12 of the front side.

[0054] The air conditioner outdoor unit includes a fan 20, which can be an axial fan that discharges air in an axial direction.

[0055] The fan 20 can include a hub having a cylindrical shape, and a plurality of blades arranged in a circumferential direction of the hub.

[0056] A fan motor 21 is connected to one side of the fan 20. The fan motor 21 is driven to provide a rotational force to the fan 20. The fan motor 21 is fixed to the housing 10 by a motor bracket.

[0057] The air conditioner outdoor unit comprises a heat exchanger 30 arranged in the shell 10 corresponding to the air inlet 11 on the side of the shell 10. The heat exchanger 30 is used for heat exchange with the air introduced through the air inlet 11.

[0058] Figure 2 The middle arrow shows the air flow direction. When the air conditioner outdoor unit is working, the outdoor air enters the shell 10 from the air inlet 11 under the driving action of the fan 20, exchanges heat with the heat exchanger 30, and is blown out by the air outlet 12.

[0059] The shell 10 is provided with a middle partition plate 16. The middle partition plate 16 divides the space in the shell 10 into a fan cavity and a compressor cavity arranged on the left and right.

[0060] The front end of the middle partition plate 16 can be connected with the front side plate 15, and the rear end of the middle partition plate 16 can be connected with the right end plate of the heat exchanger 30.

[0061] The heat exchanger 30, the fan 20, the fan motor 21, etc. are arranged in the fan cavity. The air inlet 11 and the air outlet 12 are respectively communicated with the fan cavity.

[0062] The compressor cavity is provided with a compressor 40. The bottom end of the compressor 40 is connected with the bottom plate 13 of the shell 10.

[0063] The running compressor 40 is the main noise and vibration source of the air conditioner. In order to avoid the vibration of the compressor 40 from being transmitted outward and affecting the use experience of the user, vibration control is needed.

[0064] There are three kinds of vibration control schemes. The first kind is to control from the excitation source, that is, to improve the vibration of the compressor body. If the mass exists eccentricity or the matching gap is not suitable, etc., the vibration of the compressor will increase. The vibration of the compressor body can be improved by optimizing the dynamic balance of the compressor rotor and optimizing the assembly process, etc. At present, the assembly and manufacturing process of the compressor cannot be greatly improved, so the improvement effect of the compressor body is not large.

[0065] The second kind is to control the vibration on the transmission path, that is, to consume the vibration of the compressor body through the rubber damping pad, etc., and to reduce the transmission of the compressor vibration to the sheet metal (i.e. the shell 10).

[0066] The third kind is to control the receiver of the vibration, that is, to reduce the vibration of the sheet metal at the end of the vibration transmission path, and to reduce the vibration of the sheet metal by increasing the stiffness / thickness of the sheet metal. This scheme needs to increase the thickness of the sheet metal, or to improve by increasing the die of the sheet metal, but the cost rises greatly and the effect is limited.

[0067] Currently, the second scheme is generally used to control the vibration and noise of the compressor in the industry, that is, a damping rubber pad is arranged between the compressor 40 and the bottom plate 13.

[0068] In some embodiments, referring to Figure 3 and Figure 4 , the compressor 40 includes a compressor body 41 and a support plate 42. The support plate 42 is connected to the bottom end of the compressor body 41. Exemplarily, the support plate 42 can be fixed to the compressor body 41 by welding to become an integral whole.

[0069] The support plate 42 and the bottom plate 13 can be connected by fasteners such as bolts, screws, etc., so as to realize the installation of the compressor 40 in the shell 10.

[0070] The support plate 42 of the compressor 40 and the bottom plate 13 are connected by the first rubber pad 70.

[0071] The fastening bolt 51 is arranged in the bottom plate 13 from bottom to top. The fastening bolt 51 can be fixed to the bottom plate 13 by welding.

[0072] The support plate 42 is pressed on the upper part of the first rubber pad 70. The first rubber pad 70 is sleeved on the fastening bolt 51, and the bottom end of the first rubber pad 70 is pressed on the bottom plate 13.

[0073] The fastening nut 52 cooperates with the fastening bolt 51 to fasten the compressor 40.

[0074] In this way, the vibration of the compressor 40 is attenuated by the first rubber pad 70, and the vibration transmitted from the compressor 40 to the bottom plate 13 is reduced.

[0075] In some embodiments, referring to Figure 5 and Figure 6 , the support plate 42 of the compressor 40 and the bottom plate 13 are connected by a damping assembly.

[0076] The damping assembly includes the first rubber pad 70. The first rubber pad 70 is arranged in the support plate 42.

[0077] The damping assembly includes the second rubber pad 80. The second rubber pad 80 is arranged in the bottom plate 13.

[0078] The fastening bolt 51 is arranged in the first rubber pad 70 and the second rubber pad 80. The fastening nut 52 cooperates with the fastening bolt 51 to fasten the first rubber pad 70 and the second rubber pad 80. Since the support plate 42 of the compressor 40 is connected to the first rubber pad 70, and the bottom plate 13 is connected to the second rubber pad 80, the cooperation of the fastening nut 52 and the fastening bolt 51 also fastens the compressor 40 and the bottom plate 13.

[0079] In this embodiment, the first rubber pad 70 is arranged between the support plate 42 and the fastener (the fastening bolt 51 and the fastening nut 52), and the second rubber pad 80 is arranged between the bottom plate 13 and the fastener. The vibration of the compressor 40 cannot be transmitted to the bottom plate 13 through the fastener, and the vibration noise of the outdoor unit of the air conditioner can be reduced.

[0080] In some embodiments, the first rubber pad 70 has an exposed portion 71 on the upper side of the support plate 42. The bottom of the second rubber pad 80 has a first limiting portion 81 on the lower side of the bottom plate 13.

[0081] When the fastening bolt 51 is installed from bottom to top, the head of the fastening bolt 51 contacts the first limiting portion 81 of the second rubber pad 80, and does not contact the bottom plate 13. The first limiting portion 81 separates the head of the fastening bolt 51 from the bottom plate 13, and ensures the soft connection between the fastening bolt 51 and the bottom plate 13.

[0082] The fastening nut 52 contacts the exposed portion 71 of the first rubber pad 70, and does not contact the support plate 42. The exposed portion 71 separates the fastening nut 52 from the support plate 42, and ensures the soft connection between the fastening nut 52 and the support plate 42.

[0083] In some embodiments, the bottom end of the first rubber pad 70 abuts against the bottom plate 13, so that the gravity of the compressor 40 mainly acts on the first rubber pad 70, and the axial force acting on the second rubber pad 80 is reduced, and the second rubber pad 80 is prevented from being pulled out of the bottom plate 13 by the axial force.

[0084] In some embodiments, at least the upper portion of the first rubber pad 70 has a radial spacing from the fastening bolt 51.

[0085] Since the first rubber pad 70 is mainly used to support the compressor 40, when the compressor 40 vibrates, the first rubber pad 70 deforms. Since the radial gap between the first rubber pad 70 and the fastening bolt 51 is large, the movement of the fastening bolt 51 following the deformation of the first rubber pad 70 is reduced, and the connection reliability of the fastening bolt 51 is ensured.

[0086] In some embodiments, referring to Figures 6 to 8 , the first rubber pad 70 is clamped on the support plate 42, and the connection reliability of the first rubber pad 70 and the support plate 42 is improved.

[0087] The support plate 42 is provided with a first mounting hole 421. The first rubber pad 70 is clamped on the first mounting hole 421.

[0088] The first rubber pad 70 comprises a first connecting portion 72. The first connecting portion 72 is arranged in the first mounting hole 421 and connected to the lower end of the exposed portion 71.

[0089] The first rubber pad 70 comprises a support portion 73. The support portion 73 is connected to the lower end of the first connecting portion 72 and located on the lower side of the support plate 42.

[0090] The outer diameter of the exposed portion 71 is greater than the hole diameter of the first mounting hole 421, and the outer diameter of the support portion 73 is greater than the hole diameter of the first mounting hole 421. The exposed portion 71 and the support portion 73 are clamped on the support plate 42 from top to bottom.

[0091] The exposed portion 71 can limit the downward movement of the first rubber pad 70, thereby avoiding the first rubber pad 70 from being pulled out of the support plate 42 downward. The support portion 73 can limit the upward movement of the first rubber pad 70, thereby avoiding the first rubber pad 70 from being pulled out of the support plate 42 upward.

[0092] The first rubber pad 70 is clamped on the support plate 42, avoiding the first rubber pad 70 from being pulled out of the support plate 42.

[0093] In some embodiments, the outer periphery of the exposed portion 71 has a conical surface. The small-diameter end of the conical surface is on the top, and the large-diameter end of the conical surface is on the bottom. The conical surface has a guiding effect on the exposed portion 71 passing through the first mounting hole 421, which is beneficial to the installation of the first rubber pad 70 on the support plate 42.

[0094] During installation, the exposed portion 71 is deformed by extrusion to pass through and out of the first mounting hole 421.

[0095] In some embodiments, referring to Figure 6 , Figure 9 and Figure 10 , the second rubber pad 80 is clamped on the bottom plate 13, which can increase the connection reliability of the second rubber pad 80 and the bottom plate 13.

[0096] The bottom plate 13 is provided with a second mounting hole 131. The second rubber pad 80 is clamped on the second mounting hole 131.

[0097] The second rubber pad 80 comprises a second connecting portion 82. The second connecting portion 82 is arranged in the second mounting hole 131 and connected to the upper end of the first limiting portion 81.

[0098] The second rubber pad 80 comprises a second limiting portion 83. The second limiting portion 83 is connected to the upper end of the second connecting portion 82. The second limiting portion 83 is located on the upper side of the bottom plate 13.

[0099] The outer diameter of the first limiting portion 81 is greater than the hole diameter of the second mounting hole 131. The outer diameter of the second limiting portion 83 is greater than the hole diameter of the second mounting hole 131, and the second limiting portion 83 and the first limiting portion 81 are clamped on the bottom plate 13 from the top to bottom direction, and the second rubber pad 80 is clamped on the bottom plate 13.

[0100] The first limiting portion 81 can limit the upward movement of the second rubber pad 80, thereby avoiding the upward escape of the second rubber pad 80 from the bottom plate 13. The second limiting portion 83 can limit the downward movement of the second rubber pad 80, thereby avoiding the downward escape of the second rubber pad 80 from the bottom plate 13.

[0101] In some embodiments, the outer peripheral surface of the second limiting portion 82 has a conical surface. The small-diameter end of the conical surface is upward, and the large-diameter end of the conical surface is downward. The conical surface has a guiding effect on the second limiting portion 82 passing through the second mounting hole 131, which is conducive to the installation of the second rubber pad 80 on the bottom plate 13.

[0102] During installation, the extrusion deformation of the second limiting portion 82 causes the second limiting portion 82 to pass through and out of the second mounting hole 131.

[0103] In some embodiments, the bottom of the supporting portion 73 is provided with an upwardly recessed accommodating cavity 731 for accommodating the upper part of the second rubber pad 80.

[0104] The part of the second rubber pad 80 located on the upper side of the bottom plate 13 is completely located in the accommodating cavity 731.

[0105] In some embodiments, the height of the part of the second rubber pad 80 located on the upper side of the bottom plate 13 is H1, and the height of the supporting portion 73 is H2, H1≥(1 / 3)H2. In this way, it can be ensured that the height of H1 will not be too small, avoiding the case that the upper part of the second rubber pad 80 escapes from the first rubber pad 70 due to the vibration of the compressor 40 when H1 is too small.

[0106] In some embodiments, the second rubber pad 80 includes a plug-in portion 84. The plug-in portion 84 is connected to the upper end of the second limiting portion 82. The outer diameter of the plug-in portion 84 is smaller than the hole diameter of the second mounting hole 131, so as to facilitate the plug-in portion 84 to pass out of the second mounting hole 131.

[0107] The plug-in portion 84 is in a cylindrical shape. The distance from the top end of the plug-in portion 84 to the bottom end of the second limiting portion 83 is H1.

[0108] In some embodiments, with reference to Figure 9 , the bottom plate 13 is provided with an upwardly protruding profiled protrusion 132. The second mounting hole 131 is arranged on the profiled protrusion 132.

[0109] The profiled protrusion 132 can enhance the structural strength of the bottom plate 13 to avoid deformation of the bottom plate 13 under stress, and in addition, the increase in structural strength can reduce the vibration of the bottom plate 13.

[0110] With reference to Figure 6 , the first limiting portion 81 of the second rubber pad 80 is located at the lower side of the profiled protrusion 132. Since the profiled protrusion 132 is higher than the bottom surface of the bottom plate body 133 in the height direction, the distance from the bottom surface of the first limiting portion 81 to the bottom surface of the bottom plate body 133 can be reduced, thereby avoiding that the first limiting portion 81 protrudes too much below the bottom plate body 133.

[0111] In some embodiments, with reference to Figure 5 and Figure 9 , the support plate 42 has a plurality of support legs 422 distributed along the circumferential direction. For example, the support plate 42 has three support legs 422. The first mounting hole 421 is arranged on the support leg 422.

[0112] The profiled protrusion 132 is provided with three profiled protrusions corresponding to the support legs 422.

[0113] In some embodiments, with reference to Figure 6 and Figure 10 , the bottom of the second rubber pad 80 is provided with an upwardly recessed accommodating groove 811 for accommodating the head of the fastening bolt 51.

[0114] In the assembled state, the head of the fastening bolt 51 is located in the accommodating groove 811 of the second rubber pad 80. The second rubber pad 811 forms a wrapping around the head of the fastening bolt 51 except for the bottom surface, which can ensure that the head of the fastening bolt 51 does not touch the bottom plate 13 when the compressor 40 vibrates even when the head of the fastening bolt 51 is close to the bottom plate 13.

[0115] In some embodiments, with reference to Figure 9 and Figure 10 , the periphery of the second mounting hole 131 is provided with a first positioning groove 134. The first positioning groove 134 is formed by the periphery of the second mounting hole 131 being outwardly recessed.

[0116] The periphery of the second connecting portion 82 of the second rubber pad 80 is provided with a protruding first positioning block 821. The first positioning block 821 cooperates with the first positioning groove 134.

[0117] When the second connecting portion 82 is inserted into the second mounting hole 131, the first positioning block 821 is located in the first positioning groove 134.

[0118] The cooperation between the first positioning block 821 and the first positioning groove 134 can serve as a positioning function for the second rubber pad 80, preventing the second rubber pad 80 from rotating relative to the bottom plate 13.

[0119] It can be understood that in other embodiments, the first positioning block 821 and the first positioning groove 134 can be interchanged, i.e., the first positioning block is arranged on the bottom plate 13 and the first positioning groove is arranged on the second connecting portion 82.

[0120] In some embodiments, referring to Figure 10 and Figure 11 The inner wall of the accommodating groove 811 formed on the second rubber pad 80 is provided with a second positioning block 812. The head of the fastening bolt 51 is provided with a second positioning groove 511 in the form of a notch. The second positioning groove 511 cooperates with the second positioning block 812.

[0121] When the head of the fastening bolt 51 is installed in the accommodating groove 811, the second positioning block 812 is located in the second positioning groove 511.

[0122] The cooperation between the second positioning block 812 and the second positioning groove 511 can play a positioning role on the fastening bolt 51, preventing the fastening bolt 51 from rotating and falling off relative to the rubber assembly, and ensuring the stable connection of the fastening bolt 51.

[0123] It can be understood that in other embodiments, the second positioning block 812 and the second positioning groove 511 can be interchanged, that is, the second positioning block 812 is provided on the head of the fastening bolt 51, and the second positioning groove 511 is provided on the second rubber pad 80.

[0124] The material, hardness and size of the first rubber pad 70 and the second rubber pad 80 can be adjusted according to actual use requirements.

[0125] As can be seen from the above, by providing the first rubber pad 70 connected with the support plate 42 and the second rubber pad 80 connected with the bottom plate 14, the complete flexible connection between the compressor 40 and the bottom plate 13 is realized, and the compressor 40 is completely isolated from the bottom plate 3. Compared with the rigid connection of the fastening bolt 51 and the bottom plate 13, the vibration reduction effect of the present application is better, and the vibration of the compressor body 41 is greatly reduced through the first rubber pad 70 and the second rubber pad 80, which can effectively improve the compressor vibration noise problem of the outdoor unit of the air conditioner and improve the comfort of the user when using the air conditioner.
