Description

Technical Field

[0001] The present application relates to the technical field of air conditioners, and particularly to an indoor unit of an air conditioner. Background Art

[0002] When the indoor unit of an air conditioner operates in a cooling mode, condensed water is generated. Therefore, a drainage pump is usually provided in the indoor unit of the air conditioner to drain the condensed water. The vibration generated by the drainage pump during operation is transmitted to the outer shell sheet metal through the bracket.

[0003] Since the current air conditioners all adopt large-area thin plate structures, which have characteristics such as small stiffness and fast response, when subjected to the vibration of the drainage pump, the sheet metal generates forced vibration and radiates noise outward, which will affect the user experience.

Detailed Embodiments

[0030] To make the purpose and implementation manner of this application clearer, the following will clearly and completely describe the exemplary implementation manner of this application with reference to the drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0031] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0032] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0033] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application may be understood according to specific circumstances.

[0034] In the present application, the air conditioner performs a refrigeration cycle 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 conditioned and heat-exchanged.

[0035] 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.

[0036] 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 utilizing the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. During the whole cycle, the air conditioner can adjust the temperature of the indoor space.

[0037] 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.

[0038] The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner serves as a heater in the heating mode, and when the indoor heat exchanger is used as an evaporator, the air conditioner serves as a cooler in the cooling mode.

[0039] The air conditioner according to an embodiment of the present application can be an all-in-one machine in which the indoor unit and the outdoor unit are integrated in one housing, or can be a split machine in which the indoor unit and the outdoor unit are independent and separately installed.

[0040] The following takes the indoor unit in the split machine and the air duct machine with the indoor unit installed on the ceiling as examples to introduce the present application:

[0041] Refer to Figures 1 to 3 As shown in, the air conditioner indoor unit according to an embodiment of the present application includes a housing 10, and a plurality of components constituting a refrigeration cycle are installed in the housing 10.

[0042] The housing 10 is in a cuboid shape. Among a set of opposite sides of the housing 10, an air inlet 11 is provided on one side, and an air outlet 12 is provided on the other side. Indoor air is introduced into the housing 10 through the air inlet 11 and sent into the indoor space through the air outlet 12.

[0043] In an example of an installation scenario, the air inlet 11 can be docked with the air inlet grille of the ceiling decoration. Thus, indoor air can flow into the housing 10 through the air inlet grille and the air inlet 11. An air outlet flange can be provided outside the air outlet 12, and the air outlet flange can extend into the indoor space through a connecting air duct.

[0044] Specifically refer to Figure 2 As shown in, a middle partition 13 can be provided in the housing 10. The space in the housing 10 is divided into an air inlet chamber and an air outlet chamber by the middle partition 13, wherein the air inlet chamber is communicated with the air inlet 11, and the air outlet chamber is communicated with the air outlet 12.

[0045] The air conditioner indoor unit can include a fan 20, which is arranged in the air inlet chamber. The fan 20 can adopt a centrifugal fan, and the air flow at the exhaust end of the fan 20 blows towards the air outlet chamber through the middle partition 13.

[0046] The air conditioner indoor unit can include a heat exchanger 30, which is arranged in the air outlet chamber. The heat exchanger 30 is used to absorb heat from the air introduced into the housing 10 or transfer heat to the air.

[0047] Under the action of the fan 20, indoor air enters the air inlet chamber from the air inlet 11, then flows into the air outlet chamber through the fan 20, and flows towards the air outlet 12 after heat exchange through the heat exchanger 30.

[0048] During the refrigeration process, the refrigerant on the indoor side is in a low-temperature state. Through the heat exchange of the heat exchanger 30 on the indoor side, the low-temperature refrigerant exchanges heat with the indoor air, which causes water in the air to condense. The condensed water adheres to the surface of the heat exchanger 30 and drips into the water receiving tray 40 below after accumulation.

[0049] The water receiving tray 40 can be connected to a drain pipe externally connected to the housing 10, and the condensed water is discharged to the outside of the housing 10.

[0050] Specifically referring to Figure 3 , the indoor unit of the air conditioner may include a drainage pump 50. The drainage pump 50 can be arranged above the water receiving tray 40 and is used to discharge the condensed water in the water receiving tray 40.

[0051] The suction end of the drainage pump 50 can correspond to the drainage groove of the water receiving tray 40, and the drainage end of the drainage pump 50 can communicate with a drain pipe joint 60 connected to the housing 10. The drain pipe joint 60 can be connected to an external drain pipe. When the drainage pump 50 works, the condensed water can be discharged from the housing 10 through the drain pipe.

[0052] Referring to Figure 4 , an installation frame 51 is connected to the drainage pump 50; the installation frame 51 is connected to a bracket 14 connected to the housing 10, so as to realize the installation of the drainage pump 50 in the indoor unit.

[0053] Specifically, the bracket 14 is L-shaped. Its vertical side wall is connected to the rear cover plate 15 of the housing 10, and its horizontal side wall is connected to the installation frame 51.

[0054] When the drainage pump 50 works, due to the high-speed rotation of the motor rotor in the drainage pump 50, the drainage pump 50 will generate relatively large vibrations. And the installation frame 51 is usually fixed to the bracket 14 by screws and can be regarded as a rigid connection. Therefore, the vibrations of the drainage pump 50 can be directly transmitted to the whole machine housing 10. Most of the current indoor unit housings adopt a large-area thin plate structure, which has the characteristics of small stiffness and fast response. When excited by the vibrations of the drainage pump 50, it is very easy to cause noise problems.

[0055] Referring to Figure 12 , in the prior art, the drainage pump 50 and the installation frame 51 are fixed into a whole by screws. A groove is provided on the installation frame 51 for installing a rubber pad 70. Three flanging holes 142 are designed on the bracket 14 and tapped. The screw 80 passes through the rubber pad 70 and is connected to the flanging hole 142 of the bracket 14, so as to fix the drainage pump 50, the installation frame 51, and the rubber pad 70.

[0056] Currently, this method attenuates the vibration of the drainage pump 50 through the rubber pad 70 to ensure a soft connection between the drainage pump 50 and the screw 80. However, there is still a hard connection with direct contact between the screw 80 and the bracket 14, without vibration damping effect. Therefore, the vibration can be transmitted to the bracket 14 through the screw 80 and then to the right side cover plate 15 through the bracket 14.

[0057] To solve the above technical problems, the present application mainly improves the vibration transmission path of the drainage pump 50.

[0058] Referring to Figures 4 to 6 , a first connection portion 141 is provided on the bracket 14. A second connection portion 511 corresponding to the first connection portion 141 is provided on the mounting bracket 51.

[0059] The first connection portion 414 and the second connection portion 511 can be in the shape of holes. The rubber pad 70 is inserted through the first connection portion 141 and the second connection portion 511, and the rubber pad 70 is stuck on the bracket 14 and the mounting bracket 51.

[0060] The bracket 14 and the mounting bracket 51 are only connected through the rubber pad 70, and no screws are used between them, truly realizing a soft connection between the bracket 14 and the mounting bracket 51. The vibration transmission path of the drainage pump 50 only passes through the rubber pad 70, with better vibration damping effect, and can effectively solve the vibration noise problem of the drainage pump 50.

[0061] According to an embodiment of the present application, referring to Figure 7 and Figure 8 , the rubber pad 70 includes a first limiting portion 71, and the first limiting portion 71 is clamped between the bracket 14 and the mounting bracket 51, which can separate the bracket 14 and the mounting bracket 51 to avoid the direct vibration transmission of the mounting bracket 51 to the bracket 14.

[0062] The rubber pad 70 includes a second limiting portion 72, and the second limiting portion 72 is connected to the end of the rubber pad 70. The mounting bracket 51 is clamped between the second limiting portion 72 and the first limiting portion 71. The second limiting portion 72 and the first limiting portion 71 can play a role in installation limiting to prevent the rubber pad 70 from coming out of the mounting bracket 51.

[0063] The rubber pad 70 includes a third limiting portion 73, and the third limiting portion 73 is connected to the end of the rubber pad 70 opposite to the second limiting portion 72. The bracket 14 is clamped between the third limiting portion 73 and the first limiting portion 71. The third limiting portion 73 and the first limiting portion 71 can play a role in installation limiting to prevent the rubber pad 70 from coming out of the bracket 14.

[0064] The rubber pad 70 includes a first insertion portion 74, and the first insertion portion 74 is connected between the first limiting portion 71 and the third limiting portion 73. The first insertion portion 74 is inserted into the first connection portion 141 of the bracket 14.

[0065] The outer diameter of the first insertion part 74 is smaller than the outer diameters of the first limiting part 71 and the third limiting part 73, so that a first groove 741 is formed on the outer peripheral side of the first insertion part 74, and the bracket 14 can be stuck at the first groove 741.

[0066] The rubber pad 70 includes a second insertion part 75, and the second insertion part 75 is connected between the first limiting part 71 and the second limiting part 72. The second insertion part 75 is inserted into the second connecting part 511 of the mounting bracket 51.

[0067] The outer diameter of the second insertion part 75 is smaller than the outer diameters of the first limiting part 71 and the second limiting part 72, so that a second groove 751 is formed on the outer peripheral side of the second insertion part 75, and the mounting bracket 51 can be stuck at the second groove 751.

[0068] The outer diameters of the first limiting part 71, the second limiting part 72, and the third limiting part 73 can be the same, which can simplify the manufacturing mold of the rubber pad 70 and reduce the production cost.

[0069] The first connecting part 141 and the second connecting part 511 are circular and complete hole shapes, so that the rubber pad 70 can be prevented from coming out along the radial direction of the hole.

[0070] In some embodiments, since the outer diameter of the third limiting part 73 is larger than the inner diameter of the first connecting part 141. During assembly, in order to enable the third limiting part 73 to pass through the first connecting part 141 smoothly, an inner hole 76 is provided on the rubber pad 70.

[0071] The inner hole 76 is arranged on the third limiting part 73 and extends along the direction in which the rubber pad 10 passes through the bracket 14. In this way, the inner hole 76 gives the third limiting part 73 a deformation space. When the third limiting part 73 passes through the first connecting part 141, the third limiting part 73 squeezes and contracts towards the center of the circle, and after passing through the first connecting part 141 smoothly, the third limiting part 73 returns to its original state.

[0072] A chamfer can be provided at the outer end of the third limiting part 73, which has a guiding effect on the installation of the third limiting part 73 towards the first connecting part 141 and can improve the assembly efficiency.

[0073] In some embodiments, the inner hole 76 can extend to the first limiting part 71. In this way, the deformation space of the rubber pad 70 can be made larger. The third limiting part 73 can not only contract towards the center of the circle, but also deform towards the direction of the first limiting part 71, which is more conducive to the installation of the third limiting part 73 towards the first connecting part 141.

[0074] In some embodiments, the inner hole 76 can include a first hole section 761, and the first hole section 761 is arranged on the first limiting part 71.

[0075] The inner hole 76 may include a second hole section 762 which is disposed on the third limiting portion 73. The second hole section 762 extends towards the first hole section 761 to communicate with the first hole section 761. The inner diameter of the second hole section 762 may be smaller than that of the first hole section 761.

[0076] Due to the arrangement of the first hole section 761, the third limiting portion 73 can be deformed towards the first limiting portion 71. Even when the inner diameter of the second hole section 762 is small and the radial deformation space of the third limiting portion 73 is limited, the third limiting portion 73 can still smoothly pass through the first connecting portion 141.

[0077] After the assembly is completed, since the distance between the bracket 14 and the mounting frame 51 is fixed, the axial deformation space of the third limiting portion 73 is restricted. At the same time, the inner diameter of the second hole section 762 is relatively small, and the radial deformation space of the third limiting portion 73 is also relatively small, so that it is relatively difficult for the third limiting portion 73 to disengage from the first connecting portion 141.

[0078] Therefore, the arrangements of the first hole section 761 and the second hole section 762 make it easier to install the third limiting portion 73 and ensure that it is not easy to fall off. In addition, the arrangement of the inner hole 76 reduces the stiffness of the rubber pad 70 and improves the vibration damping effect of the rubber pad 70.

[0079] In some embodiments, the second limiting portion 72 needs to pass through the second connecting portion 511. Therefore, the specific structure at the second limiting portion 72 may be the same as that of the above-mentioned third limiting portion 73, which will not be elaborated here.

[0080] In some embodiments, referring to Figure 9 , the mounting frame 51 includes a first plate 513 and a second plate 514 which are connected to each other. The second connecting portion 511 is located at the splicing position of the first plate 513 and the second plate 514. During assembly, the second limiting portion 72 does not need to pass through the second connecting portion 511.

[0081] Combined with Figure 6 , the mounting frame 51 has a connecting wall 512, and the second connecting portion 511 is provided on the connecting wall 512.

[0082] There are two relatively arranged first plates 513. One end of the first plate 513 can be connected to the drainage pump 50 by screws, and a hem 5131 is provided at the other end of the first plate 513.

[0083] The second plate 514 is connected between the two hems 5131. After the second plate 514 is connected to the hems 5131, the connecting wall 512 is formed.

[0084] The edge of the hem 5131 is provided with a first notch portion 5132; the edge of the second plate 514 is provided with a second notch portion 5141. The first notch portion 5132 and the second notch portion 5141 are spliced into a second connecting portion 511.

[0085] During assembly, the first notch portion 5132 of the hem 5131 and the second notch portion 5141 of the second plate 514 can be respectively installed circumferentially at the second groove 751 of the rubber pad 70. In this way, it is not necessary to pass the second limiting portion 72 through the second connecting portion 511 for installation.

[0086] In this embodiment, since the second limiting portion 72 does not need to pass through the second connecting portion 511, an inner hole 76 may not be provided at the second limiting portion 72. In this way, the second limiting portion 72 is not easily deformed, and it can be ensured that the second limiting portion 72 is not easily detached after assembly.

[0087] The area of the first notch portion 5132 can be larger than that of the second notch portion 5141. In this way, when installing the second plate 514, it only needs to slightly deform the rubber pad 70 to snap the second notch portion 5141 into the second groove 751 of the rubber pad 70, improving the assembly efficiency.

[0088] According to an embodiment of the present application, the edge of the second plate 514 facing the first plate 513 is provided with an extension portion 5142, and the extension portion 5142 abuts against the outer surface of the first plate 513. A screw passes through the extension portion 5142 and the first plate 513, thereby connecting the first plate 513 and the second plate 514.

[0089] The first plate 513 may be provided with a flanged screw hole, and the screw passes through the extension portion 5142 and is connected to the flanged screw hole of the first plate 513.

[0090] According to an embodiment of the present application, there are three second notch portions 5141. There are three extension portions 5142.

[0091] There are two second notch portions 5141 at the splicing position of the second plate 514 and one of the hems 5131. There is one extension portion 5142 between these two second notch portions 5141.

[0092] There is one second notch portion 5141 at the splicing position of the second plate 514 and the other hem 5131. There is one extension portion 5142 on each side of this second notch portion 5141.

[0093] The rubber pads 70 are distributed in a three-point pattern, and the three rubber pads 70 can ensure the stability of the connection of the drainage pump 50.

[0094] In some embodiments, the first connecting portion 141 and the above-mentioned second connecting portion 511 are also formed by splicing two parts. That is, the bracket 14 includes a first plate and a second plate connected to each other. The first connecting portion 141 is disposed at the splicing position of the first plate and the second plate.

[0095] In this embodiment, the third limiting portion 73 does not need to pass through the first connecting portion 141. Therefore, an inner hole 76 may not be provided at the third limiting portion 73.

[0096] In some embodiments, the connecting wall 512 on the mounting bracket 51 is connected to the bracket 14. The connecting wall 512 is located above the bracket 14.

[0097] In the embodiments of the present application, by lifting the connecting wall 512 of the mounting bracket 51 above the bracket 14, the stability of the drainage pump 50 can be better improved.

[0098] An installation groove may be formed between the mounting bracket 51 and the drainage pump 50. The bracket 14 is inserted into the installation groove and is connected to the mounting bracket 51 through a rubber pad 70.

[0099] In some embodiments, referring to Figure 10 and Figure 11 , the bracket 14 is an integral structure. The third limiting portion 73 needs to pass through the first connecting portion 141 of the bracket 14, and an inner hole 76 is provided at the third limiting portion 73.

[0100] The mounting bracket 51 is formed by connecting a first plate 513 and a second plate 514, and an inner hole 76 may not be provided at the second limiting portion 72.

[0101] As described above, in the air conditioner indoor unit according to the present application, the mounting bracket 51 and the bracket 14 are only connected through the rubber pad 70, and the mounting bracket 51 and the bracket 14 are completely isolated, realizing a completely flexible connection between the drainage pump 50 and the bracket 14. The vibration of the drainage pump 50 is greatly weakened through the consumption of the rubber pad 70, thereby solving the vibration and noise problems caused by the drainage pump 50.

[0102] In addition, the design of the first hole section 761 and the second hole section 762 on the rubber pad 70 makes it easier for the rubber pad 70 to be installed into the bracket 14 and the mounting bracket 51. At the same time, the inner diameter of the second hole section 762 can be set to be relatively small to ensure that the rubber pad 70 is not easily detached.

[0103] In addition, the mounting bracket 51 (bracket 14) can be set in a two-piece connection structure form. The second connecting portion 511 (first connecting portion 141) is formed by splicing two parts, and the second limiting portion 72 (third limiting portion 73) does not need to be provided with an inner hole 76, ensuring that the rubber pad 70 is not easily detached.
