Description

Technical Field

[0001] This utility model relates to air conditioners, and more particularly to an indoor unit of an air conditioner. Background Technology

[0002] Air conditioners are common household appliances in people's daily lives. Air conditioners are divided into wall-mounted air conditioners and floor-standing air conditioners. An air conditioner usually consists of an indoor unit and an outdoor unit. The indoor unit is installed on the indoor side, and the outdoor unit is installed on the outdoor side.

[0003] Existing indoor unit installation technologies vary, categorized into floor-standing, wall-mounted, and air conditioning indoor units. Among these, air conditioning indoor units are widely used due to their smaller footprint. Conventional air conditioning indoor units (often referred to as ducted units) generally include a casing, and components such as a fan, heat exchanger, drip tray, and drain pump housed within the casing.

[0004] Chinese Patent Publication No. CN219841590U discloses a ceiling-mounted indoor unit that uses a volute casing with an integrated structure on a partition to mount the fan. To ensure efficient heat exchange, an air guide assembly is also provided on the partition. This assembly drives the air guide plate to rotate via a drive component, enabling uniform heat exchange. However, because the air guide assembly requires a separate drive component to guide the air, the overall structure is complex, resulting in high manufacturing costs. Therefore, designing a technology that meets air guiding requirements while simplifying the overall structure and reducing manufacturing costs is the technical problem this invention aims to solve.

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0061] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, 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.

[0062] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve, returning the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0063] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0064] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0065] like Figure 1 - Figure 15 As shown, one embodiment of this application provides an indoor air conditioning unit, including:

[0066] The outer casing 1 is provided with an air inlet 11 and an air outlet 12. Airflow from outside the outer casing 1 enters the outer casing 1 through the air inlet and exits to the outside of the outer casing 1 through the air outlet 12.

[0067] Heat exchanger 2 is configured to exchange heat with the flowing air to form a heat exchange airflow; heat exchanger 2 is located in the housing 1, and the airflow entering the housing 1 from the air inlet 11 is heat-exchanged by the heat exchanger 2 and then output from the housing 1 from the air outlet 12.

[0068] The fan assembly 3 includes a motor 31 and a fan 32. The motor 31 drives the fan 32 to rotate, so that the external airflow enters the housing 1 through the air inlet 11 and the airflow in the housing 1 is output from the air outlet 12.

[0069] Electrical box 4 contains a circuit board 41. Circuit board 41 integrates components such as a controller to control the operation of the indoor unit of the air conditioner.

[0070] Water collection tray 6 is arranged at the bottom of heat exchanger 2 and is used to collect water generated during defrosting of heat exchanger 2.

[0071] The water pump assembly 5 includes a water pump 51, which is capable of pumping water out of the water receiving tray 6.

[0072] In one embodiment of this application, the fan assembly may further include a mounting component, the mounting component being provided with a through port 341, and the mounting component forming a fixed mounting area and a volute.

[0073] In another embodiment of this application, such as Figure 15 As 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.

[0074] In one embodiment, the second mounting member is provided with an air guide 3411, which is configured to guide at least a portion of the airflow output from the through-port 341 to the outside of the through-port 341 and flow towards the heat exchanger 2.

[0075] An air guide portion 3411 is provided on the second surface of the second mounting member at the edge of the through opening, and the air guide portion extends obliquely out of the second surface.

[0076] Specifically, the air guide is formed on the second surface of the second mounting member 34, and the air guide 3411 is arranged at the through port 341, thereby guiding the airflow output from the through port 341 to the heat exchanger 2.

[0077] Since the air guide 3411 is arranged at an angle relative to the second surface of the second mounting member 34, the airflow output from the through-hole 341 will be transported outward along the surface of the air guide 3411 toward the outside of the through-hole 341.

[0078] This effectively increases the coverage area of ​​the airflow output from the through-hole, enabling uniform heat exchange in the heat exchanger. It eliminates the need for additional complex air guide components, simplifying the overall structure and reducing manufacturing costs while meeting air guide requirements.

[0079] In one embodiment, the air guides 3411 are distributed on both sides of the through opening 341; the air guides 3411 on both sides of the same through opening 341 are arranged opposite to each other, and the air guides 3411 extend obliquely toward the heat exchanger 2.

[0080] Specifically, for the same through-hole 341, air guides 3411 are provided on both sides of the through-hole 341 along the length 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.

[0081] In one embodiment, a plurality of the through-holes are arranged side by side along the length of the heat exchanger.

[0082] In another embodiment of this application, in order to better guide the airflow driven by the fan 32 from the through port 341, an outwardly extending insert portion 336 is provided on the first volute portion 331 formed on the first mounting member 33. The insert portion is inserted into the through port 341 and extends toward the heat exchanger.

[0083] Specifically, during assembly, the first mounting part 33 can be inserted into the through port 341 through the insertion part 336, and during the air delivery process by the fan, the insertion part 336 forms a volute structure to guide the airflow out from the through port 341.

[0084] In one embodiment, the insertion part 336 is provided with a third recessed structure 337, and a seventh reinforcing rib 338 is provided in the third recessed structure 337, and the seventh reinforcing rib 338 has a third notch structure 339.

[0085] Specifically, since the first volute is integrally formed on the first mounting member 33, in order to satisfy the requirement that the insert portion 336 forms a volute tongue structure, the insert portion 336 forms a third recessed structure 337 so that the surface of the insert portion 336 forms a curved surface of the volute tongue, while also satisfying the requirement that the overall thickness of the first mounting member 33 is relatively uniform, so as to improve the quality of injection molding.

[0086] The seventh reinforcing rib 338 provided in the third recessed structure 337 can effectively enhance the structural strength of the insert 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, and can also ensure that the seventh reinforcing rib 338 can be smoothly demolded during demolding, reducing the occurrence of cooling shrinkage.

[0087] In one embodiment, the motor is disposed in a fixed mounting area, the fan is disposed in the volute cavity, and the volute cavity is connected to the through port.

[0088] Specifically, the motor will be fixedly installed through the fixed mounting area formed by the mounting components, while the fan is located in the volute formed in the mounting components to meet the air delivery requirements.

[0089] In one embodiment of this application, the mounting component can be a split structure, that is, the mounting component can include a first mounting member 33, on which a first volute portion 331 and a first mounting portion 332 are provided.

[0090] In one embodiment, the mounting component may include a second mounting member 34, which has 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.

[0091] The support portion 343 protrudes from the first surface and has a hollow interior. A second mounting portion 344 is provided on the support portion 343. A first reinforcing rib 345 is provided on the second surface of the second mounting portion 344, and the first and second surfaces are arranged facing away from each other.

[0092] The first mounting member 33 is detachably mounted on the second mounting member 34, and a fixed mounting area is formed between the first mounting part 332 and the second mounting part 344. The motor 31 is mounted in the fixed mounting area. A volute cavity is formed between the first volute part 331 and the corresponding second volute part 342. The volute cavity is connected to the corresponding through port 341. The fan 32 is mounted in the corresponding volute cavity, and the motor 31 is configured to drive the fan 32 to rotate in the volute cavity.

[0093] In one embodiment, the second mounting member 34 is disposed in the housing 1 and divides the interior of the housing 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.

[0094] Specifically, the heat exchanger 2 and the fan assembly 3 are installed inside the outer casing 1. During use, the fan assembly 3 drives the airflow to flow inside the outer casing 1, so that the outside air enters the air inlet cavity of the outer casing 1 from the air inlet 11, and is driven by the fan 32 to enter the air outlet cavity from the through-hole 341 to exchange heat with the heat exchanger 2. Finally, the heat-exchanged gas is output to the outside from the air outlet 12.

[0095] Specifically, the fan assembly 3 needs to meet the requirements for installing the motor 31 and the fan 32.

[0096] For the installation of fan 32, the first volute portion 331 provided on the first mounting member 33 and the second volute portion 342 provided on the second mounting member 34 cooperate to form a volute cavity, so that 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, causing air outside the volute cavity to be drawn into the volute cavity and output from the through port 341.

[0097] For the installation of motor 31, since motor 31 is relatively heavy, it is necessary to meet the requirements for effective installation support of motor 31 during transportation. For the second mounting member 34, a support portion 343 is formed at the part where motor 31 is installed and fixed. The support portion 343 protrudes from the first surface of the second mounting member 34, thereby effectively increasing the overall structural strength of the part of the second mounting member 34 with the support portion 343.

[0098] A second mounting portion 344 extends outward from the support portion 343 and is used to mount and fix the motor 31. During the assembly process 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 onto 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.

[0099] In actual use, the motor 31 is fixedly suspended on the second mounting part 344 via the first mounting part 332. The second mounting part 344 needs to bear the weight of the motor 31 and the fan 32, while the support part 343 will provide sufficient strength support to the second mounting part 344 to ensure that the structure meets the requirements of use.

[0100] As for the second mounting component 34, the fan assembly 3 is fixedly installed in the housing 1 through the second mounting component 34. The second mounting component 34 needs to meet the installation requirements of the motor 31, fan 32 and the first mounting component 33. Therefore, the overall structural strength of the second mounting component 34 itself is required to be high.

[0101] In one embodiment of this application, a first reinforcing rib 345 may be formed on the second surface of the second mounting member 34.

[0102] The first reinforcing rib 345 is distributed on the other side of the second volute portion 342, the support portion 343, and the second mounting portion 344. On the one hand, the first reinforcing rib 345 can improve the overall structural strength of the second mounting member 34 to meet the requirements of mounting to the outer shell 1. On the other hand, the first reinforcing rib 345 is 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.

[0103] As for the outer surface of the support part 343, since no reinforcing ribs are formed on its outer surface, the structure of the first surface of the second mounting part 34 can be simplified as much as possible while meeting the functional requirements of the mounting structure, so as to reduce the processing difficulty of the second mounting part 34.

[0104] By providing functional structures such as a volute and a support 343 on the first surface of the second mounting member 34, the installation requirements of the fan 32 and the motor 31 are met. Furthermore, the support 343 protruding from the first surface can effectively improve the load-bearing capacity of the motor 31, thereby meeting the structural support strength requirements of the second mounting member 344 during the installation and operation of the motor 31. 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. 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 relevant 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 is reduced while meeting the structural strength requirements of the second mounting member 34.

[0105] 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, the notch of the first notch structure 3451 facing the air outlet cavity.

[0106] Specifically, a first notch structure 3451 is additionally provided for some of the first reinforcing ribs 345, so as to further enhance the structural strength of the first reinforcing ribs 345 in a specific area by configuring the first notch structure 3451 on the first reinforcing ribs 345.

[0107] 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 achieve the requirement of increasing the structural strength of the area, thereby meeting the structural strength requirements and reducing the processing difficulty.

[0108] In one embodiment of this application, a connecting protrusion 3434 is further provided on the first surface of the second mounting member 34 between the support portion 343 and the second volute portion 342.

[0109] 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 located at least partially in the first recessed structure 34341 has the first notch structure 3451.

[0110] The first recessed structure 34341 is formed in the connecting protrusion 3434.

[0111] 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 between them is improved by connecting the protrusion 3434.

[0112] 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 provided 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.

[0113] In one embodiment of this application, a second reinforcing rib 3431 is provided 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 the inside to the outside toward the opening 3432 in the hollow structure of the support portion 343.

[0114] Specifically, the second mounting part 34 is generally manufactured by injection molding. In order to facilitate demolding and reduce the processing difficulty, and to further increase the structural strength of the support part 343 itself, a second reinforcing rib 3431 can be provided in the hollow structure formed by the support part 343 to improve the structural strength of the support part 343.

[0115] During the demolding process, the opening 3432 formed by the support part 343 can be used for smooth demolding. Furthermore, the second reinforcing rib 3431 extends from the inside to the outside towards the opening 3432, which also facilitates the smooth demolding of the second mounting part 34, thereby reducing the processing difficulty while meeting the structural strength requirements.

[0116] In another embodiment of this application, the support portion 343 extends 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.

[0117] Specifically, the support 343 extends in the width direction of the second mounting member 34, thereby making the support 343 stand upright in the use state, so as to effectively improve the structural strength of the second mounting member 34 in the width direction.

[0118] Correspondingly, in order to reduce the processing difficulty and facilitate demolding, the opening 3432 is arranged at the end of the support 343 away from the first mounting part 33, and the second reinforcing rib 3431 is also in a vertical state to facilitate the demolding process of the mold.

[0119] In another embodiment, the second reinforcing rib has a second notch structure 3434, the notch of the second notch structure facing the opening; the opening is arranged at the end of the support portion away from the first mounting member.

[0120] Specifically, the second reinforcing rib formed within the support portion 343 has a relatively high overall height. By setting a second notch structure, it is possible to facilitate the injection molding of the second reinforcing rib, improve the structural strength of the second reinforcing rib, and make it more conducive to demolding production.

[0121] In another embodiment of this application, a support extension 3435 is integrally formed on the first surface of the second mounting member. The support extension 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.

[0122] Specifically, the support extension connected to the support part extends to the edge of the second mounting part, so that the support part and the support extension part cooperate to enhance the structural strength in the height direction of the second mounting part. In this way, the complexity of the structure of the second mounting part can be effectively simplified, and the processing difficulty of the second mounting part is reduced while meeting the structural strength requirements of the second mounting part.

[0123] In one embodiment, a second recessed structure 34351 is provided on the second surface of the second mounting member 34, which is recessed toward the first surface, and the second recessed structure is formed in the support extension.

[0124] Specifically, the second recessed structure 34351 can meet the requirements of reducing the weight and material of the support extension 3435. Furthermore, during the injection molding process, the overall thickness of the support extension 3435 matches that of the second mounting part 34, thereby reducing the impact of the cooling and shrinkage of the injection molding material on the processing quality.

[0125] In another embodiment of this application, the second volute portion 342 is arranged on top of the first volute portion 331 during use, and the second volute portion 342 extends outward from the first surface of the second mounting member 34 and forms an arc surface.

[0126] 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 arc direction of the second volute portion 342 and is arranged vertically.

[0127] Specifically, a 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 3422, and in the use state, the third reinforcing rib 3421 is also arranged in a vertical direction. In this way, demolding is convenient during mold release, and the processing difficulty can be effectively reduced.

[0128] In one embodiment, since the second mounting member 34 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 provided between the second mounting portion 344 and the two adjacent second volute portions 342.

[0129] A fourth reinforcing rib 3461 is provided on the surface of the connecting part 346 away from the first volute part 331, and the fourth reinforcing rib 3461 is arranged vertically.

[0130] Specifically, the second mounting portion 344 and the second volute portion 342 are both arranged to extend toward the first surface away from 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, while the other end of the second mounting portion 344 and the other end of the second volute portion 342 can be connected by the connecting portion 346 to achieve structural reinforcement.

[0131] A fourth reinforcing rib 3461 is also provided on the surface of the connecting part 346 opposite to the first mounting member 33 to enhance its structural strength. Furthermore, since the fourth reinforcing rib 3461 is also arranged vertically in the service state, it facilitates demolding and effectively reduces processing difficulty.

[0132] In another embodiment, a fifth reinforcing rib 3441 is provided on the surface of the second mounting part 344 facing away from the first mounting member 33.

[0133] Specifically, the fifth reinforcing rib 3441 is arranged vertically. Since the second mounting part 344 needs to support the motor 31, it has high requirements for its own structural strength. In order to enhance the structural strength of the second mounting part 344, the fifth reinforcing rib 3441 can be provided on the second mounting part 344.

[0134] Similarly, in order to facilitate demolding and reduce processing difficulty, the fifth reinforcing rib 3441 is provided on the surface of the second mounting part 344 that is opposite to the first mounting part 33.

[0135] In use, the fifth reinforcing rib 3441 is also arranged vertically. This facilitates demolding and effectively reduces processing difficulty.

[0136] In another embodiment, the edge of the second mounting member 34 away from the first volute portion 331 is provided with a flange structure 347.

[0137] The flange structure 347 has a sixth reinforcing rib 3471 on the surface opposite to the first volute portion 331, and the sixth reinforcing rib 3471 is arranged vertically.

[0138] Specifically, the second mounting member 34 is connected between the bottom plate and the top plate of the outer casing 1. When the second mounting member 34 is connected to the top plate, the connection area between it and the outer casing 1 is increased by means of the flange structure 347.

[0139] In one embodiment, the flange structure 347 can be fixed to the top plate of the outer casing 1 by screws.

[0140] In another embodiment, in order to further improve the structural strength of the flange structure 347, a sixth reinforcing rib 3471 is provided on its outer surface.

[0141] In use, the sixth reinforcing rib 3471 is also arranged vertically. This facilitates demolding and effectively reduces processing difficulty.

[0142] As can be seen from the above, 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 component 34 are all arranged vertically when the indoor unit of the air conditioner is suspended and installed. This is to meet the requirements of the structural strength enhancement design of the functional structure extending outward from the second mounting component 34.

[0143] 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 part 34. When the whole is demolded, it can meet the requirements of smooth demolding, simplify the structure of the mold and reduce the processing difficulty.

[0144] In another embodiment of this application, in order to facilitate the assembly of the first mounting member 33 and the second mounting member 34, a snap-fit ​​portion 333 and a positioning portion 334 are provided on the first mounting member 33.

[0145] The second mounting part 34 is provided with a snap-fit ​​part 348 and a positioning part 349. The snap-fit ​​part 333 is snapped together with the snap-fit ​​part 348, and the positioning part 334 is connected to the positioning part 349.

[0146] Specifically, in order to reduce the amount of screws used and simplify the assembly process of the first mounting part 33 and the second mounting part 34, the first mounting part 33 and the second mounting part 34 can be pre-assembled together by snap-fit.

[0147] In actual use, the physical manifestations of the snap-fit ​​part 333 and the snap-fit ​​mating part 348 can have various structural mating forms, such as the mating of the claw and the slot, or the use of a snap-fit ​​structure, etc., which will not be limited or elaborated here.

[0148] In one embodiment, a positioning groove 330 is provided on the first mounting member between two adjacent first volute portions, and the support extension portion 3435 is located in the positioning groove.

[0149] Specifically, the positioning groove is configured to engage with the support extension so that the first mounting member slides on the support extension. Thus, when the first mounting member 33 is assembled onto the second mounting member 34, the support extension 3435 engages with the positioning groove 330 to guide the first mounting member 33 onto the second mounting member 34.

[0150] In one embodiment, a chamfer structure 34352 is formed between the second recessed structure 34351 and the second surface, the chamfer structure 34352 extending outward toward the second recessed structure.

[0151] Specifically, the chamfered structures 34352 formed on both sides of the second recessed structure 34351 are more conducive to mold demolding during injection molding.

[0152] In one embodiment, the end face of the support extension is provided with a first connecting portion 34353, and the second mounting member 34 is provided with a flange structure 347 at the edge away from the first volute portion 331, and a second connecting portion 3472 is provided on the flange structure 347.

[0153] The first connecting part is fixedly connected to the outer shell, and the second connecting part is fixedly connected to the outer shell.

[0154] In another embodiment, the specific method for mounting and fixing the motor 31 via the first mounting part 332 and the second mounting part 344 can be implemented using the following structure.

[0155] The first mounting section 332 includes two first frames 3321 formed on the first mounting member 33.

[0156] Two first frames 3321 are arranged side by side. The first frames 3321 have an arc-shaped structure. A structural reinforcement 3322 is also provided between the two first frames 3321. The structural reinforcement 3322 extends along the length of the rotating shaft of the motor 31.

[0157] The second mounting section 344 includes two second frames 3442 formed on the second mounting member 34.

[0158] Two second frames 3442 are arranged side by side, and mounting grooves (unmarked) are formed on the surfaces of the second frames 3442 that are opposite to the first frame 3321.

[0159] 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.

[0160] Specifically, the motor 31 is installed between the first mounting part 332 and the second mounting part 344. The first frame 3321 formed by the first mounting part 332 and the second frame 3442 formed by the second mounting part 344 will clamp the corresponding ends of the motor 31 so that the motor 31 is fastened to the first mounting part 332 and the second mounting part 344.

[0161] Since the motor 31 is relatively heavy, in order to improve the connection reliability between the first frame 3321 and the second frame 3442, after the first mounting part 33 and the second mounting part 34 are snapped together, the first frame 3321 and the second frame 3442 can be further fastened with screws to improve the connection reliability of the motor 31 mounting part.

[0162] In another embodiment, such as Figure 6 As shown, at least one end of the motor is provided with a shock-absorbing ring 311.

[0163] An anti-rotation part 3443 is provided on the first mounting part and / or the second mounting part.

[0164] The anti-rotation part is connected to the damping ring and configured to restrict the rotation of the damping ring relative to the second mounting member.

[0165] Specifically, the end of the motor 31 is provided with a shock-absorbing ring 311, which can play a role in damping the vibration during the operation of the motor 31. The shock-absorbing ring 311 is sandwiched between the first frame 3321 and the second frame 3442, which can securely fix the motor 31 between the first frame 3321 and the second frame 3442.

[0166] Since the first frame 3321 and / or the second frame 3442 are provided with anti-rotation part 3443, the anti-rotation part 3443 cooperates with the damping ring 311 to restrict the rotation of the damping ring 311 relative to the first frame 3321 and the second frame 3442, so as to ensure that the motor 31 will not rotate on its own during operation.

[0167] In one embodiment, in order to ensure that the anti-rotation part 3443 can restrict the rotation of the damping ring 311, the following measures are taken.

[0168] The anti-rotation part 3443 can be a pressure rib protruding from the first mounting part and / or the second mounting part. The pressure rib presses against the outer circumference of the damping ring 311 to limit the rotation of the damping ring 311.

[0169] Alternatively, the anti-rotation part 3443 can be an anti-rotation protrusion provided on the first mounting part and / or the second mounting part, while the damping ring 311 is provided with an anti-rotation groove, and the anti-rotation protrusion is locked in the anti-rotation groove to limit the rotation of the damping ring 311.

[0170] 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 tilted upwards due to being blocked by the damping ring 311. 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 less than 15 degrees.

[0171] In another embodiment, a wiring portion 34444 is provided on the second mounting portion and / or the second volute portion, the wiring portion being configured to limit the routing of the wires on the motor.

[0172] Specifically, after the motor 31 is installed on the first mounting part 33 and the second mounting corner 34, the wires on the motor 31 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.

[0173] In one embodiment, the physical manifestation of the wiring section 34444 can be a structure such as a wire clip or a hook.

[0174] In one embodiment of this application, the outer casing 1 may adopt the following structural form.

[0175] In one embodiment, the housing includes a base plate 13.

[0176] In one embodiment, the housing includes a top plate 14.

[0177] In one embodiment, the housing includes a front panel 15, on which an air outlet 12 is provided.

[0178] The front panel 15 is located between the bottom plate 13 and the top plate 14.

[0179] In the actual assembly process, the top plate 14 is usually inverted, and then the second mounting component, front panel 15, heat exchanger 2, water pump assembly 5, electrical box 4, water receiving tray 6 and bottom plate 13 are assembled in the following order.

[0180] To facilitate the assembly of the heat exchanger 22 onto the top plate 14, a side plate 16 can be provided at one end of the top plate 14 to form the side wall of the outer shell 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 gap.

[0181] In this way, when assembling the heat exchanger 2, the piping 21 on the heat exchanger 2 does not need to be assembled by perforation, but is placed directly on the end of the top plate 14 away from the side plate 16.

[0182] Specifically, an installation gap is formed between the mounting components, 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 mounting plate 51 is disposed between the lower flange 17 and the base plate 13 and covers the installation gap.

[0183] By setting a side plate 16 at one end of the top plate 14 to meet the requirements of connecting 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.

[0184] When assembling the heat exchanger 2, it is assembled on the inverted top plate 14, and the piping 21 of the heat exchanger 2 can extend from 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 its posture, realizing single-person assembly operation, reducing assembly costs and improving assembly efficiency.

[0185] In one embodiment, such as Figure 11 As shown, the side panel 16 can be integrated with the top panel 14, that is, one end of the top panel 14 is bent to form the side panel 16.

[0186] Alternatively, in another embodiment, the side plate 16 and the top plate 14 are separate structures, with the side plate 16 fixed to the top plate 14 by screws.

[0187] During assembly, after the top plate 14 is inverted on the operating surface and the front panel 15 is attached, the heat exchanger 2 can be installed. The heat exchanger 2 can be arranged horizontally and placed above the top plate 14. The empty area at the other end of the top plate 14 away from the side plate 16 is used to meet the installation requirements of the heat exchanger 2's piping 21 extending outside the outer casing 1.

[0188] Compared with the existing technology of configuring side plates on both sides of the top plate and opening a hole in one side plate for the pipe 21 to extend out, the other side of the top plate 14 is not configured with a side plate 16, which allows the heat exchanger 2 to be directly placed on the top plate 14 in a horizontal arrangement for assembly.

[0189] In one embodiment of this application, the base plate 13 is a split structure for easy maintenance.

[0190] In one embodiment, the base plate 13 includes a first plate 131, which is arranged below the water receiving tray 6.

[0191] In one embodiment, the base plate 13 includes a second plate 132, which is arranged below the fan assembly 3.

[0192] Since the fan assembly 3 needs to be maintained as needed, the second plate 132 can be detachably installed on the first plate 131.

[0193] In one embodiment, in order to achieve a screwless bottom appearance design, the first plate 131 is provided with a socket 133, and the second plate 132 is provided with a hook 134. The hook 134 is inserted into the socket 133 to connect the first plate 131 and the second plate 132 together.

[0194] In one embodiment, the ends of the first plate 131 and the second plate 132 may be provided with folded edges to be fixedly connected to the side plate by screws.

[0195] In one embodiment, the base plate 13 includes a noise reduction plate 133, which can reduce the noise of the airflow drawn in by the air inlet 11 of the housing 1.

[0196] The noise reduction plate is disposed on the inner edge of the first plate and located above the second plate.

[0197] Specifically, after the outer casing 1 is hoisted into the user's home, the second plate 132 is disassembled to form the air inlet 11.

[0198] When the housing 1 is exposed to air at the bottom, it is easy to generate wind noise at the area between the inner edge of the first plate 131 and the mounting component. The noise reduction plate 133 is used to reduce noise in this area to reduce operating noise and improve the user experience.

[0199] In another embodiment of this application, the water pump assembly 5 may include a mounting plate 51, on which a water pump 52 is mounted, and the mounting plate 51 is mounted on the housing 1.

[0200] In one embodiment, the mounting plate 51 adopts a split structure to facilitate the disassembly and assembly of the water pump assembly 5.

[0201] In one embodiment, the mounting plate 51 may include a first mounting sub-plate 513, and the water pump 52 is mounted on the first mounting sub-plate 513.

[0202] 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 base plate 13, the front panel 15, and / or mounting components.

[0203] The first mounting subplate 513 is detachably mounted on the second mounting subplate 514.

[0204] 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 into independent modules and then assembled onto the top plate 14 together.

[0205] During later maintenance, it is only necessary to remove the first mounting subplate 513 from the second mounting subplate 514. Then, the first mounting subplate 513 and the water pump 52 can be removed from the outer casing 1 together for maintenance. The second mounting subplate 514 is still set on the outer casing 1 to meet the overall installation requirements of the outer casing 1.

[0206] In one embodiment, the detachable connection between the first mounting sub-plate 513 and the second mounting sub-plate 514 can be achieved by screws, clips, or other means, and no limitation is imposed here.

[0207] In some embodiments, to facilitate the assembly of the water pump 52, a pump frame 53 is provided on the first mounting plate 513, the pump frame 53 is provided with a cantilever structure, and the water pump 52 is mounted on the pump frame 53.

[0208] Specifically, a pump bracket 53 is provided on the inner surface of the first mounting plate 513, which allows the water pump 52 to be suspended on one side of the first mounting plate 513.

[0209] In another embodiment, the cantilever structure is also provided with an extension bracket 54, which extends toward the water receiving tray 6, and a water level sensor 55 is also provided on the lower end of the extension bracket 54.

[0210] Specifically, the water pump 52 and the water level sensor 55 are assembled together on the pump frame 53, so that the water pump 52 and the water level sensor 55 can be uniformly assembled through the mounting plate 51, realizing a modular design to improve assembly efficiency.

[0211] In one embodiment, a buffer component (unmarked) is also 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 noise caused by the vibration transmitted to the pump frame 53.

[0212] In this way, the housing 1 only needs to be equipped with a side plate 16 on one side, instead of having side plates 16 on both sides and openings to meet the installation requirements of the water pump 52, which reduces the number of parts and improves assembly efficiency.

[0213] In one embodiment, the water pump 52 is arranged at one end of the heat exchanger 2, and the water pump 52 is arranged near the air outlet 12; the piping 21 is arranged between the water pump 52 and the mounting component.

[0214] Specifically, the water pump 52 is positioned away from the electrical box 4, while the piping 21 of the heat exchanger 2 is close to the electrical box 4. This makes it easier for the temperature sensor and electronic expansion valve mounted on the piping 21 to be connected to the circuit board 41 inside the electrical box 4, facilitating rapid on-site assembly.

[0215] In one embodiment, in order to effectively position the protruding pipe 21 by means of the mounting plate 51 after the water pump assembly 5 is assembled, the edge of the lower flange 17 is provided with a first notch 171, and the edge of the mounting plate 51 is provided with a second notch 511. The first notch 171 and the second notch 511 are joined together, and the pipe 21 is located in the first notch 171 and the second notch 511.

[0216] Specifically, during the assembly process, after the heat exchanger 2 is placed on the top plate 14, the piping 21 will be secured in the corresponding first notch 171. Then, the water pump assembly 5 is installed on the top plate 14 via the mounting plate 51. The second notch of the mounting plate 51 will cooperate with the first notch 171 to limit the piping 21 between the mounting plate 51 and the lower flange 17.

[0217] In another embodiment of this application, the water receiving tray 6 is provided with a drain pipe 61, which extends to the outside of the housing 1 via an installation gap.

[0218] In one embodiment, since the drain pipe 61 also needs to extend to the outside of the housing 1, a third notch 512 is provided on the edge of the mounting plate 51 in order to position the drain pipe 61. The drain pipe 61 is disposed in the third notch 512 and located between the mounting plate 51 and the base plate 13.

[0219] In some embodiments, the positioning of the piping 21 can also be achieved directly through the mounting plate 51, that is, the mounting plate 51 is provided with pipe holes, and the piping 21 extends to the outside of the housing 1 through the pipe holes.

[0220] During assembly, after the heat exchanger 2 is mounted onto the base plate 13, when assembling the water pump assembly 5, the pipe holes on the mounting plate 51 of the water pump assembly 5 are first aligned with the piping 21 so that the piping 21 can be inserted into the corresponding pipe holes. Because the water pump assembly 5 is relatively lightweight, it is also convenient for operators to make adjustments.

[0221] In one embodiment, the mounting component is provided with a positioning rib 3410, which is configured to support the water receiving tray 6 when the outer shell 1 is inverted, and is also configured to press against the edge of the water receiving tray 6 when the outer shell 1 is upright.

[0222] 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.

[0223] The positioning rib 3410 extends above the edge of the water receiving tray 6 and abuts against the edge of the water receiving tray 6.

[0224] Specifically, the second surface of the second mounting member 34 is formed with positioning ribs 3410, which are arranged laterally and extend along the length of the water receiving tray 6.

[0225] During assembly, after the top plate 14 is inverted and the second mounting piece 34 and heat exchanger 2 are assembled in place, the water receiving tray 6 is inverted and placed on the heat exchanger 2, and the edge of the water receiving tray 6 will overlap the positioning rib 3410.

[0226] By adding additional positioning ribs to the mounting components, the positioning ribs can support the edge of the water tray during assembly. This allows the water tray to overlap the positioning ribs when the outer casing is inverted for assembly. The positioning ribs, together with the heat exchanger, can more effectively and reliably support the water tray, thereby improving the assembly accuracy of the water tray, improving the assembly quality, and ultimately improving the overall assembly quality of the air conditioner indoor unit.

[0227] In another embodiment of this application, in order to reduce the number of screws used in the assembly process of heat exchanger 2, the following structural improvements are made to the assembly method of heat exchanger 2.

[0228] like Figure 11 As shown, a first support member 18 is provided on one side of the outer casing 1, and the first support member 18 is used to support the installation of the heat exchanger 2.

[0229] In one embodiment, a support member 181 may be provided on the first support member 18, and a threaded hole is provided at one end of the support member 181. The support member 181 is used to support the heat exchanger 2.

[0230] In one embodiment, a limiting component 182 may be provided on the first support member 18, which is used to limit the heat exchanger 2.

[0231] The limiting component 182 is located at the other end of the supporting component 181. One end of the first end plate 22 is fixed to the supporting component 181 by screws, and the other end of the first end plate 22 is located between the supporting component 181 and the limiting component 182.

[0232] In one embodiment, the outer casing 1 is further provided with a second support member 19, one end of the second support member 19 is provided with a threaded hole, and one end of the second support member 19 is a pre-installed part.

[0233] In one embodiment, a pre-installed mating part is provided at the other end of the second end plate 23, the pre-installed part and the pre-installed mating part are connected together, and one end of the second end plate 23 is fixed to the second support member 19 by screws.

[0234] A first support member 18 and a second support member 19 are arranged opposite to each other in the outer casing 1. Both supports can meet the requirement that the end plate of the heat exchanger 2 be fastened with screws. During assembly, the other end of the end plate can also be fixed without screws.

[0235] When installing the first end plate 22, the first end plate 22 will overlap the support member 181, the first end plate 22 will be inserted into the area between the support member 181 and the limiting member 182, and then the first end plate 22 will be fixed to the support member 181 by screws.

[0236] When installing the second end plate 23, the second end plate 23 is pre-assembled with the pre-assembly part through the pre-assembly mating part, and then the second end plate 23 is fixed to the second support member 19 by screws.

[0237] After assembly and hoisting, the first end plate 22 can be supported by the bottom support column by the limiting component 182, and the second end plate 23 is supported by the pre-assembled fitting part and the pre-assembled part. The end plates will be further tightened by screws to improve the assembly reliability.

[0238] By setting two opposing support members in the outer shell 1, one end of the end plate of the heat exchanger 2 is fixedly connected to the corresponding support member with screws, while the other end of the end plate of the heat exchanger 2 is not fixed with screws but only has a limiting fit with the support member.

[0239] In the actual assembly process, when the operator fixes the heat exchanger 2, at least one screw is needed on the end plates at both ends of the heat exchanger 2 to achieve the fixed assembly of the heat exchanger 2, so as to reduce the number of screws used and thus improve the assembly efficiency.

[0254] The fan assembly 3 may also include a mounting bracket 35, which is used to fix the motor 31 in conjunction with the second mounting component 34.

[0255] The first mounting member 33 has only a first volute portion 331, the second mounting member 34 has a through opening 341, the first surface of the second mounting member 34 has a second volute portion 342 and a support portion 343, and the support portion 343 has a second mounting portion 344.

[0256] The fixed bracket 35 is detachably mounted on the second mounting part 34, and a fixed mounting area is formed between the fixed bracket 35 and the second mounting part 344, and the motor 31 is mounted in the fixed mounting area.

[0257] The motor 31 is installed and fixed by means of an independently configured fixing bracket 35, which cooperates with the second mounting part 344 of the second mounting component 34.

[0258] In one embodiment, the fixing bracket 35 has a frame structure and has a first fixing part 351, a second fixing part 352 and two clamping parts 353, which are connected between the first fixing part 351 and the second fixing part 352.

[0259] The second mounting portion 344 includes two second frames 3442 formed on the second mounting member 34. The two second frames 3442 are arranged side by side, and clamping grooves (not marked) are formed on the surfaces of the second frames 3442 opposite to the fixed bracket 35.

[0260] The first fixing part 351 and the second fixing part 352 are fixedly connected to the second mounting part 34, and the end of the motor 31 is fixed between the corresponding clamp part 353 and the second frame 3442.

[0262] In one embodiment, since the motor 31 is relatively heavy, in order to improve the connection reliability between the clamp part 353 and the second frame 3442, the fixing bracket 35 can be fixed to the second mounting part 34 with screws to improve the connection reliability of the motor 31 mounting part.

[0263] In another embodiment, in order to save on the amount of screws used, the first fixing part 351 is provided with an outwardly extending insertion part 354, and the support part 343 is provided with an insertion mating part 3433.

[0264] The insertion part 354 is inserted together with the insertion mating part 3433, and the second fixing part 352 is fixed to the second mounting part 34 by screws.

[0265] Specifically, during the assembly of the motor 31, the motor 31 is first placed between the two second frames 3442 of the second mounting component 34, the plug-in part 354 of the fixing bracket 35 is inserted into the plug-in mating part 3433, the fixing bracket 35 is flipped so that the second fixing part 352 is against the connecting part 346, and then the second fixing part 352 and the connecting part 346 are fastened together with screws.

[0266] In another embodiment of this application, such as Figures 16-19 As shown, a plurality of integrally formed second volute portions 342 are formed on the second mounting member 34.

[0267] During assembly, after placing the motor 31 and fan 32 onto the second mounting member 34, the first mounting members 33 are then assembled onto the second mounting member 34. The first volute portion 331 provided on the first mounting member 33 will cooperate with the corresponding second volute portion 342 to form a volute cavity, thereby meeting the installation requirements of the fan 32.

[0268] The motor 31 is installed and fixed by means of an independently configured fixing bracket 35, which cooperates with the second mounting part 344 of the second mounting component 34.

[0269] In one embodiment, the fixing bracket 35 is arranged between two first mounting members 33. Alternatively, when multiple first volute portions 331 are configured on the same first mounting member 33, the fixing bracket 35 can also be arranged between two adjacent first volute portions 331 on the first mounting member 33.

[0270] In another embodiment, the fan 32 is usually mounted on the support shaft 36 so as to transmit power by connecting the support shaft 36 to the rotating shaft of the motor 31. When multiple fans 32 are configured on the same support shaft 36, one end of the support shaft 36 is connected to the rotating shaft of the motor 31 by a coupling, while the other end of the support shaft 36 needs to be supported by a bearing 37.

[0271] In one embodiment, two adjacent fans 32 are connected together by a support shaft 36. One end of the support shaft 36 is connected to the rotating shaft of the motor 31, and the other end of the support shaft 36 is provided with a bearing 37.

[0272] In one embodiment, at least one first volute portion 331 is provided with a first mounting bracket 335, which is used to mount the bearing 37 on the support shaft 36.

[0273] In one embodiment, a second mounting bracket 340 is provided on the second mounting member 34, and the second mounting bracket 340 is used to mount the bearing 37 on the support shaft 36.

[0274] The bearing 37 is located between the first mounting bracket 335 and the second mounting bracket 340.

[0275] When two adjacent fans 32 are mounted and supported by the same support shaft 36, the other end of the support shaft 36 needs to be supported by a bearing 37 to ensure that the support shaft 36 can drive the two fans 32 to rotate smoothly in their respective volutes.

[0276] During assembly, the motor 31 and fan 32 are placed at their corresponding positions on the second mounting member 34, and the bearing 37, located at the free end of the support shaft 36, is placed on the second mounting bracket 340. Then, the first mounting member 33 is assembled onto the second mounting member 34 so that the bearing 37 can be fixedly mounted between the first mounting bracket 335 and the second mounting bracket 340.

[0277] The first mounting bracket 335 is connected to the second mounting bracket 340 and the bearing 37 is fixedly installed between them.

[0279] In order to improve the installation reliability of bearing 37, extend the service life of bearing 37, and reduce the noise generated by bearing 37 due to vibration during operation, a shock-absorbing component 38 is fitted on the outside of bearing 37. Bearing 37 is installed and fixed between the first mounting bracket 335 and the second mounting bracket 340 through the shock-absorbing component 38.

[0280] During use, as the motor 31 drives the support shaft 36 to rotate, the vibration generated by the fan 32 during air delivery is transmitted to the bearing 37 via the support shaft 36. The bearing 37 is encased in a shock-absorbing component 38 and sandwiched between the first mounting bracket 335 and the second mounting bracket 340. The shock-absorbing component 38 buffers the vibration generated by the bearing 37, thereby reducing noise and extending the service life of the bearing 37.

[0281] In another embodiment, to facilitate the assembly of the shock-absorbing component 38 by the operator, a limiting part 381 is provided on the shock-absorbing component 38, and the limiting part 381 extends toward the outside of the shock-absorbing component 38.

[0282] In one embodiment, a limiting groove 3401 is provided on the second mounting bracket 340, and the limiting part 381 is inserted into the limiting groove 3401.

[0283] When the operator assembles the shock absorber 38 on site, the limiting part 381 of the shock absorber 38 will be inserted into the limiting groove 3401 so that the shock absorber 38 is pre-assembled onto the second mounting bracket 340. After the first mounting bracket is fixed onto the second mounting member 34, the shock absorber 38 can be precisely clamped between the first mounting bracket 335 and the second mounting bracket 340 to ensure that the bearing 37 is accurately installed in place.
