Description

Technical Field

[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] 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 to cool or heat the indoor space.

[0063] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas 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 the heat is released to the surrounding environment through the condensation process.

[0064] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0065] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0066] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0067] like Figure 1-Figure 15 As shown, an embodiment of the present application provides an air conditioner indoor unit, comprising:

[0068] The housing 1 is provided with an air inlet 11 and an air outlet 12 . The airflow outside the housing 1 enters the housing 1 through the air inlet and is output to the outside of the housing 1 through the air outlet 12 .

[0069] The heat exchanger 2 is configured to perform heat exchange on the airflow passing through it to form a heat exchange airflow; the heat exchanger 2 is located in the housing 1, and the airflow entering the housing 1 from the air inlet 11 is output from the housing 1 from the air outlet 12 after heat exchange through the heat exchanger 2.

[0070] The fan assembly 3 includes a motor 31 and a fan 32. The motor 31 can drive the fan 32 to rotate, so that the airflow from the outside enters the housing 1 through the air inlet 11, and the airflow in the housing 1 is output from the air outlet 12.

[0071] The electrical box 4 has a circuit board 41 therein. The circuit board 41 is integrated with components such as a controller to control the operation of the indoor unit of the air conditioner.

[0072] The water receiving tray 6 is arranged at the bottom of the heat exchanger 2 and is used to collect water generated by defrosting the heat exchanger 2.

[0073] The water pump assembly 5 includes a water pump 51 , and the water pump 51 can pump and discharge the water in the water receiving tray 6 .

[0074] In one embodiment of the present application, the fan assembly may further include a mounting component, wherein the mounting component is provided with a through opening 341 , and the mounting component is formed with a fixed mounting area and a volute cavity.

[0075] In one embodiment, the motor is disposed in a fixed installation area, the fan is disposed in the volute cavity, and the volute cavity is communicated with the through-port.

[0076] Specifically, the motor is fixedly installed in a fixed installation area formed by the installation component, and at the same time, the fan is located in a volute formed in the installation component to meet the air supply requirement.

[0077] In an embodiment of the present application, the mounting component may be a split structure, that is, the mounting component may include a first mounting member 33 , and the first volute portion 331 and the first mounting portion 332 are provided on the first mounting member 33 .

[0078] In one embodiment, the mounting component may include a second mounting member 34 , the second mounting member 34 is provided with a through opening 341 , and a second volute portion 342 and a support portion 343 are provided on a first surface of the second mounting member 34 .

[0079] The support portion 343 protrudes from the first surface, the interior of the support portion 343 is a hollow structure, and a second mounting portion 344 is disposed on the support portion 343. A first reinforcing rib 345 is disposed on the second surface of the second mounting member 34, and the first surface and the second surface are arranged in back-to-back relation.

[0080] Among them, the first mounting member 33 is detachably arranged on the second mounting member 34, a fixed mounting area is formed between the first mounting portion 332 and the second mounting portion 344, and the motor 31 is arranged in the fixed mounting area; a volute cavity is formed between the first volute portion 331 and the corresponding second volute portion 342, the volute cavity is connected to the corresponding through-portion 341, the fan 32 is arranged in the corresponding volute cavity, and the motor 31 is configured to drive the fan 32 to rotate in the volute cavity.

[0081] In one embodiment, the second mounting member 34 is disposed in the outer shell 1 and divides the interior of the outer shell 1 into an air inlet cavity and an air outlet cavity, the air inlet 11 is connected to the air inlet cavity, the air outlet 12 is connected to the air outlet cavity, the first surface is located in the air inlet cavity, the second surface is located in the air outlet cavity, and the heat exchanger 2 is located in the air outlet cavity.

[0082] Specifically, a heat exchanger 2 and a fan assembly 3 are installed inside the shell 1. During use, the fan assembly 3 will drive the airflow to flow inside the shell 1, so that the outside air enters the air inlet cavity in the shell 1 from the air inlet 11, and is driven by the fan 32 to enter the air outlet cavity from the through port 341 to exchange heat with the heat exchanger 2. Finally, the gas after heat exchange is output to the outside from the air outlet 12.

[0083] The fan assembly 3 needs to meet the requirements for installing the motor 31 and the fan 32 .

[0084] For installing the fan 32, the first volute portion 331 provided on the first mounting member 33 cooperates with the second volute portion 342 provided on the second mounting member 34 to form a volute cavity, and the fan 32 is located between the first volute portion 331 and the second volute portion 342. The fan 32 rotates in the volute cavity so that air outside the volute cavity is sucked into the volute cavity and output from the through-port 341.

[0085] For the installation of the motor 31, since the motor 31 is heavy as a whole, it is necessary to meet the requirements of effective installation and support of the motor 31 during transportation. For the second mounting member 34, a support portion 343 is formed at the portion where the motor 31 is mounted and fixed, and the support portion 343 protrudes from the first surface of the second mounting member 34, so that the overall structural strength of the portion of the second mounting member 34 having the support portion 343 is effectively increased.

[0086] The support portion 343 is provided with a second mounting portion 344 extending outwardly, and the second mounting portion 344 is used to mount and fix the motor 31. During the assembly process of the motor 31 with the first mounting member 33 and the second mounting member 34, the motor 31 is first placed on the second mounting portion 344 on the second mounting member 34, and then the first mounting member 33 is assembled to the second mounting member 34. At this time, the motor 31 is fixedly mounted between the first mounting portion 332 and the second mounting portion 344.

[0087] During actual use, the motor 31 is fixedly suspended on the second mounting portion 344 through the first mounting portion 332. The second mounting portion 344 needs to bear the weight of the motor 31 and the fan 32, and the support portion 343 will provide sufficient strength support for the second mounting portion 344 to ensure that the structure meets the requirements of use.

[0088] As for the second mounting member 34, the fan assembly 3 is fixedly mounted in the housing 1 through the second mounting member 34. The second mounting member 34 needs to meet the installation requirements of the bearing motor 31, the fan 32 and the first mounting member 33. Therefore, the overall structural strength requirements of the second mounting member 34 itself are relatively high.

[0089] In one embodiment of the present application, a first reinforcing rib 345 may be formed on the second surface of the second mounting member 34 .

[0090] The first reinforcing ribs 345 are distributed on the second volute portion 342, the support portion 343 and the other side of the second mounting portion 344. On the one hand, the first reinforcing ribs 345 can be used to improve the overall structural strength of the second mounting member 34 to meet the requirements for installation on the outer casing 1. On the other hand, the first reinforcing ribs 345 are arranged on the second surface of the second mounting member 34, which can effectively simplify the structure of the first surface of the second mounting member 34.

[0091] As for the outer surface of the support portion 343, since no reinforcing ribs are formed on the outer surface, the structure of the first surface of the second mounting member 34 can simplify the structural complexity on the first surface as much as possible while meeting the requirements of the mounting structure function, so as to reduce the processing difficulty of the second mounting member 34.

[0092] Functional structures such as a volute portion and a support portion 343 are provided on the first surface of the second mounting member 34 to meet the installation requirements of the fan 32 and the motor 31, and the support portion 343 protruding from the first surface can effectively improve the load-bearing support capacity of the motor 31 to meet the requirements of the second mounting portion 344 for structural support strength during the installation and operation of the motor 31. In order to enhance the overall structural strength of the second mounting member 34, a first reinforcing rib 345 is formed on the second surface of the second mounting member 34, and the first reinforcing rib 345 is used to enhance the overall structural strength of the second mounting member 34. In this way, the complexity of the related structures on the first surface of the second mounting member 34 can be effectively simplified, and the processing difficulty of the second mounting member 34 can be reduced while meeting the structural strength requirements of the second mounting member 34.

[0093] In another embodiment, the first reinforcing rib 345 extends toward the air outlet cavity, and at least a portion of the first reinforcing rib 345 has a first notch structure 3451, and the notch of the first notch structure 3451 faces the air outlet cavity.

[0094] Specifically, a first notch structure 3451 is additionally provided for some of the first reinforcing ribs 345 , so as to configure the first notch structure 3451 on the first reinforcing ribs 345 in a specific area to further enhance the structural strength of the first reinforcing ribs 345 in the area.

[0095] In this way, without increasing the density of the first reinforcing rib 345, the structural strength of the first reinforcing rib 345 in a specific area can be locally increased by adding the first notch structure 3451 to increase the structural strength of the area, thereby meeting the structural strength requirements and reducing the processing difficulty.

[0096] In an embodiment of the present application, a connecting protrusion 3434 is further provided on the first surface of the second mounting member 34 between the supporting portion 343 and the second volute portion 342 .

[0097] In one embodiment, a first recessed structure 34341 recessed toward the first surface is provided on the second surface of the second mounting member 34, and the first reinforcing rib 345 is also provided in the first recessed structure 34341; and the first reinforcing rib 345 at least partially located in the first recessed structure 34341 has the first notch structure 3451.

[0098] The first recessed structure 34341 is formed in the connecting protrusion 3434 .

[0099] Specifically, the support portion 343 and the second volute portion 342 are formed on the first surface of the second mounting member 34 , and the structural strength therebetween is improved by connecting the protrusion 3434 .

[0100] In order to increase the structural strength of the connecting protrusion 3434 , a first recessed structure 34341 is formed on the second surface of the second mounting member 34 , and a first reinforcing rib 345 is arranged in the first recessed structure 34341 . The first notch structure 3451 formed by the first reinforcing rib 345 can locally enhance the structural strength of the connecting protrusion 3434 .

[0101] In one embodiment of the present application, a second reinforcing rib 3431 is disposed inside the hollow structure of the support portion 343 ; an opening 3432 is also formed on the support portion 343 , and the second reinforcing rib 3431 extends from inside to outside in the hollow structure of the support portion 343 toward the opening 3432 .

[0102] Specifically, for the second mounting member 34, it is generally processed by injection molding. In order to facilitate demolding to reduce the processing difficulty and further increase the structural strength of the support part 343 itself, a second reinforcing rib 3431 can be arranged in the hollow structure formed by the support part 343 to utilize the second reinforcing rib 3431 to improve the structural strength of the support part 343.

[0103] During the demolding process, the opening 3432 formed by the support portion 343 can be used for smooth demolding, and the second reinforcing rib 3431 extends from the inside to the outside toward the opening 3432, which also facilitates the smooth demolding of the second mounting member 34, thereby reducing the processing difficulty while meeting the structural strength.

[0104] In another embodiment of the present application, the support portion 343 is arranged to extend vertically along the width direction of the second mounting member 34 , and the opening 3432 is arranged at the end of the support portion 343 away from the first mounting member 33 .

[0105] Specifically, the support portion 343 extends in the width direction of the second mounting member 34 , so that when in use, the support portion 343 is arranged upright to effectively improve the structural strength of the second mounting member 34 in the width direction.

[0106] Correspondingly, in order to reduce the difficulty of processing and facilitate demoulding, the opening 3432 is arranged at the end of the support portion 343 away from the first mounting member 33, and the second reinforcing rib 3431 is also in an upright state to facilitate demoulding of the mold.

[0107] In another embodiment, the second reinforcing rib has a second notch structure 3434, and the notch of the second notch structure faces the opening; the opening is arranged at the end of the support portion away from the first mounting member.

[0108] Specifically, the overall height of the second reinforcing rib formed in the support portion 343 is relatively high. By setting the second notch structure, on the one hand, the injection molding of the second reinforcing rib can be facilitated, and on the other hand, the structural strength of the second reinforcing rib can be improved and demolding production can be more conducive.

[0109] In another embodiment of the present application, a support extension portion 3435 is integrally formed on the first surface of the second mounting member, and the support extension portion is connected to the end of the support portion and extends along the width direction of the second mounting member to the edge of the second mounting member.

[0110] Specifically, the support extension portion connected to the support portion is extended to the edge of the second mounting member, so that the structural strength of the second mounting member is enhanced by the cooperation of the support portion and the support extension portion in the height direction of the second mounting member. In this way, the complexity of the structure of the second mounting member can be effectively simplified, and the processing difficulty of the second mounting member can be reduced while meeting the structural strength requirements of the second mounting member.

[0111] In one embodiment, a second recessed structure 34351 recessed toward the first surface is disposed on the second surface of the second mounting member 34, and the second recessed structure is formed in the support extension portion.

[0112] Specifically, the second recessed structure 34351 can meet the requirements of reducing the weight and material of the support extension portion 3435, and during the injection molding process, the overall thickness of the support extension portion 3435 matches that of the second mounting member 34, thereby reducing the impact of cooling and shrinkage of the injection molding material on the processing quality.

[0113] In another embodiment of the present application, for the second volute portion 342, when in use, the second volute portion 342 is arranged on the top of the first volute portion 331, and the second volute portion 342 extends outward from the first surface of the second mounting member 34 to form an arc surface.

[0114] In order to improve the structural strength of the second volute portion 342 , a third reinforcing rib 3421 is provided on the surface of the second volute portion 342 away from the first volute portion 331 . The third reinforcing rib 3421 extends along the curvature direction of the second volute portion 342 and is arranged vertically.

[0115] Specifically, the third reinforcing rib 3421 is formed on the outer surface of the second volute portion 342, which can improve the structural strength of the second volute portion 342. Similarly, since the third reinforcing rib 3421 is arranged on the outer surface of the second volute portion 342, and in the use state, the third reinforcing rib 3421 is also arranged in a vertical direction. In this way, when the mold is demolded, demolding is convenient, and the processing difficulty can also be effectively reduced.

[0116] In one embodiment, since the second mounting member 34 itself is integrally formed with the second mounting portion 344 and the second volute portion 342, in order to improve the connection reliability between the second mounting portion 344 and the second volute portion 342, a connecting portion 346 may be further provided between the second mounting portion 344 and two adjacent second volute portions 342.

[0117] A fourth reinforcing rib 3461 is disposed on a surface of the connecting portion 346 facing away from the first volute portion 331 , and the fourth reinforcing rib 3461 is arranged upright.

[0118] Specifically, the second mounting portion 344 and the second volute portion 342 are both extended in a direction away from the first surface of the second mounting member 34, one end of the second mounting portion 344 and one end of the second volute portion 342 are respectively connected to the second mounting member 34, and the other end of the second mounting portion 344 and the other end of the second volute portion 342 can be connected via a connecting portion 346 to achieve structural reinforcement.

[0119] A fourth reinforcing rib 3461 is also provided on the surface of the connecting portion 346 facing away from the first mounting member 33 to enhance its structural strength. In addition, since the fourth reinforcing rib 3461 is also arranged in a vertical direction in the use state, it is convenient to demould when the mold is demoulded, and the processing difficulty can also be effectively reduced.

[0120] In yet another embodiment, a fifth reinforcing rib 3441 is disposed on a surface of the second mounting portion 344 facing away from the first mounting member 33 .

[0121] Specifically, the fifth reinforcing rib 3441 is arranged vertically. Since the second mounting portion 344 needs to support the motor 31 , a higher structural strength requirement is required for the second mounting portion 344 . In order to enhance the structural strength of the second mounting portion 344 , a fifth reinforcing rib 3441 may be provided on the second mounting portion 344 .

[0122] Similarly, in order to facilitate demoulding and reduce processing difficulty, the fifth reinforcing rib 3441 is arranged on the surface of the second mounting portion 344 away from the first mounting member 33 .

[0123] In the use state, the fifth reinforcing rib 3441 is also arranged in a vertical direction. In this way, when the mold is demoulded, it is convenient to demould and the processing difficulty can be effectively reduced.

[0124] In yet another embodiment, a flange structure 347 is provided on an edge of the second mounting member 34 away from the first volute portion 331 .

[0125] A sixth reinforcing rib 3471 is provided on the surface of the flange structure 347 facing away from the first volute portion 331 , and the sixth reinforcing rib 3471 is arranged vertically.

[0126] Specifically, the second mounting member 34 is connected between the bottom plate and the top plate of the housing 1 , wherein when the second mounting member 34 is connected to the top plate, the flange structure 347 is used to increase the connection area with the housing 1 .

[0127] In one embodiment, as a specific connection method, the flange structure 347 can be fixed to the top plate of the housing 1 by screws.

[0128] In another embodiment, in order to further improve the structural strength of the flange structure 347, a sixth reinforcing rib 3471 is provided on the outer surface thereof.

[0129] In the use state, the sixth reinforcing rib 3471 is also arranged in a vertical direction. In this way, when the mold is demoulded, it is convenient to demould and the processing difficulty can be effectively reduced.

[0130] It can be seen from the above that for the second reinforcing rib 3431, the third reinforcing rib 3421, the fourth reinforcing rib 3461, the fifth reinforcing rib 3441 and / or the sixth reinforcing rib 3471 configured on the second mounting member 34, when the air conditioner indoor unit is hung and installed in use, the second reinforcing rib 3431, the third reinforcing rib 3421, the fourth reinforcing rib 3461, the fifth reinforcing rib 3441 and the sixth reinforcing rib 3471 are all in an upright arrangement to meet the requirements of the structural strength reinforcement design on the functional structure portion extending outward from the second mounting member 34.

[0131] The second reinforcing rib 3431, the third reinforcing rib 3421, the fourth reinforcing rib 3461, the fifth reinforcing rib 3441 and the sixth reinforcing rib 3471 are vertically arranged on the second mounting member 34, which can meet the requirement of smooth demoulding during overall demoulding, simplify the structure of the mold and reduce the difficulty of processing.

[0132] In another embodiment of the present application, in order to facilitate the assembly of the first mounting member 33 and the second mounting member 34, a clamping portion 333 and a positioning portion 334 are provided on the first mounting member 33;

[0133] The second mounting member 34 is provided with a snap-fitting portion 348 and a positioning fitting portion 349 . The snap-fitting portion 333 is snap-fitted with the snap-fitting portion 348 , and the positioning portion 334 is connected with the positioning fitting portion 349 .

[0134] Specifically, in order to reduce the number of screws used and simplify the assembly process of the first mounting member 33 and the second mounting member 34 , the first mounting member 33 and the second mounting member 34 may be pre-assembled together by means of a clamping method.

[0135] Among them, in actual use, the performance entities of the snap-fitting portion 333 and the snap-fitting portion 348 can have a variety of structural matching forms, such as the matching of a claw and a slot, or the use of a snap-fit ​​structure, etc., which are not limited or elaborated here.

[0136] In one embodiment, a positioning groove 330 is provided on the first mounting member between two adjacent first volute parts, and the support extension portion 3435 is located in the positioning groove.

[0137] Specifically, the positioning groove is configured to cooperate with the support extension so that the first mounting member slides on the support extension. In this way, when the first mounting member 33 is assembled to the second mounting member 34, the support extension 3435 cooperates with the positioning groove 330 to guide the first mounting member 33 to be assembled to the second mounting member 34.

[0138] In one embodiment, a chamfered structure 34352 is formed between the second recessed structure 34351 and the second surface, and the chamfered structure 34352 extends toward the outer side of the second recessed structure.

[0139] Specifically, the chamfered structures 34352 formed on both sides of the second recessed structure 34351 are more conducive to demolding of the mold during injection molding.

[0140] In one embodiment, the end surface of the support extension portion is provided with a first connection portion 34353, and the second mounting member 34 is provided with a flange structure 347 at an edge away from the first volute portion 331, and the flange structure 347 is provided with a second connection portion 3472;

[0141] Wherein, the first connection portion is connected and fixed to the shell, and the second connection portion is connected and fixed to the shell.

[0142] In another embodiment of the present application, Fig.15As shown, in order to increase the coverage area of ​​the airflow output from the through-hole 341, so as to ensure that the heat exchanger 2 can exchange heat evenly.

[0143] In one embodiment, an air guide portion 3411 is disposed on the second mounting member, and the air guide portion is configured to guide at least part of the airflow output from the through opening 341 to flow toward the outside of the through opening 341 and toward the heat exchanger 2 .

[0144] An air guide portion 3411 is provided at the edge of the through opening on the second surface of the second mounting member, and the air guide portion protrudes from the second surface and extends obliquely.

[0145] Specifically, the air guide portion is formed on the second surface of the second mounting member 34 , and the air guide portion 3411 is arranged at the through-opening 341 , thereby being able to guide the airflow output from the through-opening 341 to flow toward the heat exchanger 2 .

[0146] Since the air guide portion 3411 is arranged obliquely relative to the second surface of the second mounting member 34 , the airflow output from the through-opening 341 will be transported outward along the surface of the air guide portion 3411 toward the outside of the through-opening 341 .

[0147] In this way, the coverage area of ​​the airflow output from the through-port can be effectively increased, so that the heat exchanger can exchange heat evenly without the need for additional complex air guide components. This meets the air guide requirements while simplifying the overall structure and reducing manufacturing costs.

[0148] In one embodiment, the air guide portions 3411 are distributed on both sides of the through opening 341 ; the air guide portions 3411 on both sides of the same through opening 341 are arranged away from each other, and the air guide portions 3411 extend obliquely toward the heat exchanger 2 .

[0149] Specifically, for the same through-hole 341 , air guides 3411 are provided on both sides of the through-hole 341 in the length direction of the heat exchanger 2 , and the air guides 3411 on both sides are arranged away from each other to increase the air outlet coverage area of ​​the through-hole 341 .

[0150] In one embodiment, the plurality of through openings are arranged side by side along the length direction of the heat exchanger.

[0151] In another embodiment of the present application, in order to better guide the airflow driven by the fan 32 from the through-portion 341, a plug-in portion 336 extending outward is also provided on the first volute portion 331 formed on the first mounting member 33, and the plug-in portion is inserted into the through-portion 341, and the plug-in portion extends toward the direction of the heat exchanger.

[0152] Specifically, during assembly, the first mounting member 33 can be inserted into the through-opening 341 through the inserting portion 336 , and during air supply by the fan, the inserting portion 336 forms a volute tongue structure to guide airflow to be output from the through-opening 341 .

[0153] In one embodiment, a third recessed structure 337 is disposed on the insertion portion 336 , a seventh reinforcing rib 338 is disposed in the third recessed structure 337 , and the seventh reinforcing rib 338 has a third notch structure 339 .

[0154] Specifically, since the first volute is integrally formed on the first mounting member 33, in order to satisfy the insertion portion 336 to form a volute tongue structure, the insertion portion 336 forms a third recessed structure 337 so that the surface of the insertion portion 336 forms a curved surface of the volute tongue, while also satisfying that the overall thickness of the first mounting member 33 is relatively uniform, so as to improve the quality of injection molding.

[0155] The seventh reinforcing rib 338 provided in the third recessed structure 337 can effectively enhance the structural strength of the inserting portion 336. The third notch structure 339 formed on the seventh reinforcing rib 338 can further enhance the structural strength of the seventh reinforcing rib 338 on the one hand, and can also ensure smooth demolding of the seventh reinforcing rib 338 during demolding to reduce the occurrence of cooling shrinkage on the other hand.

[0156] In another embodiment, the specific method of installing and fixing the motor 31 through the first installation portion 332 and the second installation portion 344 can be implemented by using the following structure.

[0157] The first mounting portion 332 includes two first brackets 3321 formed on the first mounting member 33 .

[0158] The two first frames 3321 are arranged side by side. The first frames 3321 are in an arc-shaped structure. A structural reinforcement portion 3322 is disposed between the two first frames 3321 . The structural reinforcement portion 3322 extends along the length direction of the rotating shaft of the motor 31 .

[0159] The second mounting portion 344 includes two second brackets 3442 formed on the second mounting member 34 .

[0160] The two second frames 3442 are arranged side by side, and a mounting groove (not marked) is formed on the surface of the second frame 3442 opposite to the first frame 3321 .

[0161] The first frame 3321 and the second frame 3442 are fixedly connected together by screws, and the end of the motor 31 is fixed between the corresponding first frame 3321 and the second frame 3442 .

[0162] Specifically, the motor 31 is installed between the first mounting portion 332 and the second mounting portion 344 , and the first frame 3321 formed by the first mounting portion 332 and the second frame 3442 formed by the second mounting portion 344 clamp the corresponding ends of the motor 31 so that the motor 31 is fastened to the first mounting portion 332 and the second mounting portion 344 .

[0163] Since the motor 31 is heavy, in order to improve the connection reliability between the first frame 3321 and the second frame 3442, after the first mounting member 33 and the second mounting member 34 are snapped together, the first frame 3321 and the second frame 3442 can be further fastened together by screws to improve the connection reliability of the mounting part of the motor 31.

[0164] In another embodiment, if Figure 6 As shown, a damping ring 311 is provided at at least one end of the motor.

[0165] A rotation-stopping portion 3443 is provided on the first mounting portion and / or the second mounting portion.

[0166] The anti-rotation portion is connected to the damping ring and is configured to limit the damping ring from rotating relative to the second mounting member.

[0167] Specifically, a shock absorbing ring 311 is provided at the end of the motor 31 to reduce shock during the operation of the motor 31. The shock absorbing ring 311 is clamped between the first frame 3321 and the second frame 3442, so that the motor 31 can be firmly fixed between the first frame 3321 and the second frame 3442.

[0168] Since the first frame 3321 and / or the second frame 3442 are provided with a stopper 3443, the stopper 3443 cooperates with the shock-absorbing ring 311 to limit the rotation of the shock-absorbing ring 311 relative to the first frame 3321 and the second frame 3442 to ensure that the motor 31 does not rotate itself during operation.

[0169] In one embodiment, in order to ensure that the anti-rotation portion 3443 can limit the rotation of the shock-absorbing ring 311.

[0170] The anti-rotation portion 3443 may be a protruding rib provided on the first mounting portion and / or the second mounting portion, and the rib is pressed on the outer circumference of the shock absorbing ring 311 to limit the rotation of the shock absorbing ring 311 .

[0171] Alternatively, the anti-rotation portion 3443 may be an anti-rotation protrusion arranged on the first mounting portion and / or the second mounting portion, and an anti-rotation groove is arranged on the shock absorbing ring 311, and the anti-rotation protrusion is stuck in the anti-rotation groove to limit the rotation of the shock absorbing ring 311.

[0172] In another embodiment, when assembling the motor 31, after one end of the first mounting member 33 is pre-installed on the second mounting member 34, the other end of the first mounting member 33 is in a tilted state due to being blocked by the damping ring 311. In order to ensure that the damping ring 311 can be effectively compressed, the tilting angle of the first mounting member 33 relative to the second mounting member 34 after pre-installation is greater than 3 degrees, and the tilting angle of the first mounting member 33 relative to the second mounting member 34 after pre-installation is less than 15 degrees.

[0173] In another embodiment, a wiring portion 34444 is provided on the second mounting portion and / or the second volute portion, and the wiring portion is configured to limit the wiring direction of the wires on the motor.

[0174] Specifically, for the motor 31, after it is installed on the first mounting member 33 and the second mounting angle 34, the wires on the motor 31 also need to be connected to the circuit board 41 of the electrical box 4, and the wires between the circuit board 41 and the motor 31 can be guided by the wiring part 34444.

[0175] In one embodiment, the wiring portion 34444 may be a structure such as a line card or a hook.

[0176] In one embodiment of the present application, the housing 1 may have the following structure.

[0177] In one embodiment, the housing includes a bottom plate 13 .

[0178] In one embodiment, the housing includes a top plate 14 .

[0179] In one embodiment, the housing includes a front panel 15 , and an air outlet 12 is disposed on the front panel 15 .

[0180] The front panel 15 is located between the bottom panel 13 and the top panel 14 .

[0181] In the actual assembly process, the top plate 14 is generally inverted, and then the second mounting member, the front panel 15, the heat exchanger 2, the water pump assembly 5, the electrical box 4, the water tray 6 and the bottom plate 13 are assembled in order.

[0182] In order to facilitate the assembly of the heat exchanger 22 onto the top plate 14, a side plate 16 may be provided at one end of the top plate 14 to form a side wall of the housing 1, while no side plate 16 is provided between the other end of the top plate 14 and the bottom plate 13 to form a vacant portion.

[0183] In this way, when assembling the heat exchanger 2 , the pipes 21 on the heat exchanger 2 do not need to be assembled by perforation, but can be directly placed at the end of the top plate 14 away from the side plate 16 .

[0184] Specifically, an installation gap is formed between the installation component, the lower flange 17, the base plate 13 and the front panel 15, the piping 21 extends to the outside of the housing 1 through the installation gap, and the installation plate 51 is arranged between the lower flange 17 and the base plate 13 and covers the installation gap.

[0185] By providing a side plate 16 at one end of the top plate 14 to meet the requirement of connection with the bottom plate 13 , the other end of the top plate 14 is not directly connected to the bottom plate 13 , so that a gap is formed between the other end of the top plate 14 and the bottom plate 13 .

[0186] When assembling the heat exchanger 2, it is assembled on the inverted top plate 14, and the pipes 21 of the heat exchanger 2 can extend through the end of the top plate 14 away from the side plate 16. In this way, the heat exchanger 2 can be directly assembled on the top plate 14 in a flat manner without tilting and adjusting the posture, realizing single-person assembly operation, thereby reducing assembly costs and improving assembly efficiency.

[0187] In one embodiment, if Fig.11 As shown, the side plate 16 can be an integral structure with the top plate 14 , that is, one end of the top plate 14 is bent to form the side plate 16 .

[0188] Alternatively, in another embodiment, the side panels 16 and the top panel 14 are separate structures, and the side panels 16 are fixed to the top panel 14 by screws.

[0189] During assembly, the top plate 14 is inverted on the operating surface and the front panel 15 is installed, and then the heat exchanger 2 can be installed. The heat exchanger 2 can be arranged horizontally and placed above the top plate 14. The vacant area at the other end of the top plate 14 away from the side plate 16 is used to meet the installation requirement that the pipes 21 of the heat exchanger 2 extend out of the housing 1.

[0190] Compared with the prior art method of configuring side panels on both sides of the top plate and opening a hole in one of the side panels for the pipe 21 to extend out, no side vertical panel 16 is configured on the other side of the top plate 14, which allows the heat exchanger 2 to be directly dropped onto the top plate 14 in a horizontal position for assembly.

[0191] In one embodiment of the present application, in order to facilitate maintenance, the bottom plate 13 is a split structure.

[0192] In one embodiment, the bottom plate 13 includes a first plate 131 , and the first plate 131 is arranged below the water receiving tray 6 .

[0193] In one embodiment, the base plate 13 includes a second plate 132 , and the second plate 132 is arranged below the fan assembly 3 .

[0194] Since the fan assembly 3 needs to be repaired as needed, the second plate 132 can be detachably mounted on the first plate 131 .

[0195] In one embodiment, in order to meet the screw-free design of the bottom appearance, a socket 133 is provided on the first plate 131, and a hook 134 is provided on the second plate 132. The hook 134 is inserted into the socket 133 to connect the first plate 131 and the second plate 132 together.

[0196] In one embodiment, the ends of the first plate 131 and the second plate 132 may be provided with folded edges so as to be fixedly connected to the side plates by screws.

[0197] In one embodiment, the bottom plate 13 includes a noise reduction plate 133 , and the noise reduction plate 133 can reduce the noise of the airflow sucked in by the air inlet 11 of the housing 1 .

[0198] Wherein, the noise reduction plate is arranged on the inner edge of the first plate and located above the second plate.

[0199] Specifically, after the housing 1 is hoisted to the user's home, the second plate 132 is disassembled to form the air inlet 11 .

[0200] When the housing 1 takes in air at the bottom, wind noise is easily generated in the area between the inner edge of the first plate 131 and the mounting component. The noise reduction plate 133 is used to perform noise reduction processing in this area to reduce the operating noise, thereby improving the user experience.

[0201] In another embodiment of the present application, the water pump assembly 5 may include a mounting plate 51 , the water pump 52 is mounted on the mounting plate 51 , and the mounting plate 51 is mounted on the housing 1 .

[0202] In one embodiment, in order to facilitate the disassembly and assembly of the water pump assembly 5 , the mounting plate 51 adopts a split structure.

[0203] In one embodiment, the mounting plate 51 may include a first mounting sub-plate 513 , and the water pump 52 is disposed on the first mounting sub-plate 513 .

[0204] In one embodiment, the mounting plate 51 may include a second mounting sub-plate 514. The second mounting sub-plate 514 is connected to the bottom plate 13, the front panel 15, and / or the mounting component.

[0205] The first mounting sub-plate 513 is detachably disposed on the second mounting sub-plate 514 .

[0206] During assembly, after the heat exchanger 2 is assembled onto the top plate 14 , the first mounting sub-plate 513 , the second mounting sub-plate 514 and the water pump 52 are pre-assembled to form an independent module and then assembled onto the top plate 14 together.

[0207] During later maintenance, it is only necessary to remove the first mounting sub-plate 513 from the second mounting sub-plate 514, and the first mounting sub-plate 513 and the water pump 52 can be removed from the outer shell 1 together to repair the water pump 52. The second mounting sub-plate 514 is still set on the outer shell 1 to meet the requirements of the overall installation of the outer shell 1.

[0208] In one embodiment, the detachable connection between the first mounting sub-plate 513 and the second mounting sub-plate 514 may be by means of screws, buckles, etc., which are not limited here.

[0209] In some embodiments, in order to facilitate the assembly of the water pump 52 , a pump frame 53 is provided on the first mounting sub-plate 513 , the pump frame 53 is provided with a cantilever structure, and the water pump 52 is disposed on the pump frame 53 .

[0210] Specifically, a pump bracket 53 is provided on the inner surface of the first mounting sub-plate 513 , and the pump bracket 53 allows the water pump 52 to be suspended on one side of the first mounting sub-plate 513 .

[0211] In another embodiment, an extension bracket 54 is further provided on the cantilever structure. The extension bracket 54 extends toward the water receiving tray 6 . A water level sensor 55 is further provided on the lower end of the extension bracket 54 .

[0212] Specifically, the water pump 52 and the water level sensor 55 are centrally assembled on the pump frame 53, so that the water pump 52 and the water level sensor 55 are uniformly assembled through the mounting plate 51, thereby realizing a modular design to improve assembly efficiency.

[0213] In one embodiment, a buffer component (not marked) is further provided between the water pump 52 and the pump frame 53. The buffer component can buffer the vibration generated during the operation of the water pump 52, thereby reducing the vibration transmitted to the pump frame 53 and causing noise.

[0214] In this way, the housing 1 only needs to be equipped with a side plate 16 on one side, and there is no need to set side plates 16 on both sides and make holes to meet the installation requirements of the water pump 52, thereby reducing the number of parts and components and improving assembly efficiency.

[0215] In one embodiment, the water pump 52 is arranged at one end of the heat exchanger 2 , and the water pump 52 is arranged close to the air outlet 12 ; the pipe 21 is arranged between the water pump 52 and the mounting component.

[0216] Specifically, the water pump 52 is arranged away from the electrical box 4, and the pipe 21 of the heat exchanger 2 is close to the electrical box 4. In this way, the temperature sensor and the electronic expansion valve installed on the pipe 21 are more convenient to be connected with the circuit board 41 in the electrical box 4, so as to facilitate quick assembly on site.

[0217] In one embodiment, in order to effectively position the protruding pipe 21 through the mounting plate 51 after assembling the water pump assembly 5, a first notch groove 171 is provided at the edge of the lower flange 17, and a second notch groove 511 is provided at the edge of the mounting plate 51. The first notch groove 171 and the second notch groove 511 are butt-jointed together, and the pipe 21 is located in the first notch groove 171 and the second notch groove 511.

[0218] Specifically, during the assembly process, after the heat exchanger 2 is placed on the top plate 14, the pipe 21 will be stuck in the corresponding first notch groove 171, and then the water pump assembly 5 will be installed on the top plate 14 through the mounting plate 51. The second notch of the mounting plate 51 will cooperate with the first notch groove 171 so that the pipe 21 is located between the mounting plate 51 and the lower flange 17 for limiting.

[0219] In another embodiment of the present application, the water receiving tray 6 is provided with a drain pipe 61 , and the drain pipe 61 extends to the outside of the housing 1 through the installation interval.

[0220] In one embodiment, since the drain pipe 61 also needs to extend to the outside of the outer shell 1, in order to position the drain pipe 61, a third notch groove 512 is further provided on the edge of the mounting plate 51, and the drain pipe 61 is arranged in the third notch groove 512 and is located between the mounting plate 51 and the base plate 13.

[0221] In some embodiments, the positioning of the pipe 21 can also be achieved directly through the mounting plate 51 , that is, the mounting plate 51 is provided with a pipe hole, and the pipe 21 extends to the outside of the housing 1 through the pipe hole.

[0222] During the assembly process, after the heat exchanger 2 is assembled on the bottom plate 13, when assembling the water pump assembly 5, the pipe hole provided on the mounting plate 51 of the water pump assembly 5 is first aligned with the pipe 21, so that the pipe 21 is inserted into the corresponding pipe hole. Since the water pump assembly 5 is light in weight, it is also convenient for operators to adjust it.

[0223] In one embodiment, a positioning rib 3410 is provided on the mounting component, and the positioning rib 3410 is configured to support the water receiving tray 6 when the shell 1 is inverted. The positioning rib 3410 is also configured to press on the edge of the water receiving tray 6 when the shell 1 is in an upright state.

[0224] The positioning rib 3410 is formed on the second surface of the second mounting member 34 , and the positioning rib 3410 extends toward the heat exchanger 2 .

[0225] The positioning rib 3410 extends to above the edge of the water receiving tray 6 and abuts against the edge of the water receiving tray 6 .

[0226] Specifically, a positioning rib 3410 is formed on the second surface of the second mounting member 34 . The positioning rib 3410 is arranged transversely and extends along the length direction of the water receiving tray 6 .
