The indoor unit in the prior art is installed in different ways, and is divided into a vertical indoor unit, a wall-mounted indoor unit and an air conditioner indoor unit. Among them, the air conditioner indoor unit is widely promoted and used because it occupies a small indoor effective space. The air conditioner indoor unit in conventional technology (usually referred to as a duct unit) generally includes a shell, and components such as a fan, a heat exchanger, a water tray and a drainage pump arranged in the shell. Chinese patent announcement number CN 112747373 A discloses a duct unit and a duct unit assembly method, wherein the duct unit includes a shell, a fan system, a heat exchange system and a drainage device, wherein the shell includes a bottom plate, two side plates, a front panel and a lower cover plate, and in order to meet the requirements of the refrigerant pipe connection of the heat exchanger, a pipe installation hole is usually provided on one of the side plates. In the actual assembly process, the heat exchanger is first tilted and carried so that the refrigerant pipe can be inserted into the pipe installation hole, and then the heat exchanger is laid flat to fix the heat exchanger in the shell. However, the heat exchanger is heavy, and when the heat exchanger is tilted and installed into the shell, it generally requires two workers to assist in the operation, which increases the assembly cost and reduces the assembly efficiency. In view of this, how to design an air conditioning technology that improves assembly efficiency is a technical problem to be solved by the present invention. Summary of the invention

[0003] In view of the problems pointed out in the background technology, the present invention proposes an air conditioner indoor unit, which reduces the number of workers required for assembly to reduce assembly costs and improve assembly efficiency.

The first mounting portion 332 is located on one side of the first volute portion 331. When a plurality of first volute portions 331 are configured, the first mounting portion 332 is located between two adjacent first volute portions 331.

[0011] The second mounting member 34 is provided with at least one through opening 341 , and the first surface of the second mounting member 34 is provided with at least one second volute portion 342 and at least one second mounting portion 344 .

[0012] The first mounting member 33 is detachably arranged on the second mounting member 34, and 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, and the volute cavity is connected to the corresponding through-portion 341, and 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.

[0013] The electrical box 4 is provided with a circuit board 41 , and a plurality of cables (not shown) are connected to the circuit board 41 .

[0014] The water pump assembly 5 includes a mounting plate 51 and a water pump 52, and the water pump is arranged on the mounting plate; Among them, the second mounting member 34 is arranged 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, and the heat exchanger 2 is located in the air outlet cavity and arranged at the bottom of the heat exchanger.

[0015] When assembled, the housing 1 at least comprises a bottom plate 13 , a top plate 14 and a front panel 15 . The front panel 15 is located between the bottom plate 13 and the top plate 14 , and an air outlet 12 is provided on the front panel 15 .

[0016] 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, the water tray 6 and the bottom plate 13 are assembled in order.

[0017] 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.

[0018] Thus, when assembling the heat exchanger 2 , the pipes 21 on the heat exchanger 2 need to be assembled in a perforated manner and are directly placed at the end of the top plate 14 away from the side plate 16 .

[0019] 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.

[0020] In the actual assembly process, Fig.25 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; or, the side plate 16 and the top plate 14 are separate structures, and the side plate 16 is fixed to the top plate 14 by screws. After the top plate 14 is inverted on the operating surface and assembled with the front panel 15, the heat exchanger 2 can be assembled, and 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 piping 21 of the heat exchanger 2 extends out of the housing 1.

[0021] Compared with the prior art method of disposing side upright plates 16 on both sides of the top plate 14 and opening a hole in one of the side upright plates 16 for the pipe 21 to extend out, no side upright plate 16 is disposed on the other side of the top plate 14, so that the heat exchanger 2 can be directly dropped onto the top plate 14 in a horizontal posture for assembly.

[0022] In some embodiments, for easy maintenance, the bottom plate 13 includes a first plate 131 and a second plate 132 connected together, the first plate 131 is arranged below the water receiving tray 6, and the second plate 132 is arranged below the fan assembly 3. Since the fan assembly 3 needs to be repaired as needed, the second plate 132 can be detachably installed on the first plate 131.

[0023] In order to meet the bottom appearance without screw design, such as Fig.10 As shown, 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, and the ends of the first plate 131 and the second plate 132 can be provided with folded edges to be fixedly connected to the side plates by screws.

[0024] 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.

[0025] 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.

[0026] In another embodiment, 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 gap.

[0027] Specifically, for the water tray 6, its 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 also provided on the edge of the mounting plate 51. The drain pipe 61 is arranged in the third notch groove 512 and is located between the mounting plate 51 and the bottom plate 13.

[0028] 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.

[0029] Specifically, 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.

[0030] 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, while 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, 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 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, thereby realizing single-person assembly operation, thereby reducing assembly costs and improving assembly efficiency.

[0031] In another embodiment of the present application, in order to facilitate the disassembly and assembly of the water pump assembly 5, the mounting plate 51 adopts a split structure, that is, the mounting plate 51 includes a first mounting sub-plate 513 and a second mounting sub-plate 514, the water pump 52 is arranged on the first mounting sub-plate 513, and the first mounting sub-plate 513 is detachably arranged on the second mounting sub-plate 514; the second mounting sub-plate 514 is connected to the base plate 13, the front panel 15, and / or the mounting component.

[0032] Specifically, during assembly, after the heat exchanger 2 is assembled on 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 on the top plate 14. During later maintenance, it is only necessary to remove the first mounting sub-plate 513 from the second mounting sub-plate 514, and then the first mounting sub-plate 513 and the water pump 52 can be removed from the housing 1 together.

[0033] As for the detachable connection method of the first mounting sub-plate 513 and the second mounting sub-plate 514, screws, buckles, etc. can be used, and there is no limitation here.

[0034] 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 .

[0035] 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 .

[0036] 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 .

[0037] 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.

[0038] The water pump 52 is supported and installed by adopting a split mounting plate 51. During assembly, the first mounting sub-plate 513 and the second mounting sub-plate 514 are assembled and connected between the top plate 14 and the bottom plate 13. When the water pump 52 needs to be disassembled and repaired, it is only necessary to remove the first mounting sub-plate 513 from the second mounting sub-plate 514 to repair the water pump 52, and the second mounting sub-plate 514 is still arranged on the outer shell 1 to meet the requirements of the overall installation of the outer shell 1. In this way, the outer shell 1 only needs to be equipped with a side plate 16 on one side, and there is no need to arrange 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.

[0039] In another embodiment of the present application, for an air conditioner indoor unit that does not require active drainage, it can drain water by gravity through the drainage pipe 61 on the water receiving tray 6, and thus it is not necessary to assemble the water pump 52 on the mounting plate 51. In the case where the water pump 52 is not assembled, a water level sensor 55 can be assembled on the mounting plate 51 as needed, so as to monitor the water level in the water receiving tray 6 by using the water level sensor 55. Of course, from the perspective of cost saving, the water level sensor 55 may not be assembled on the mounting plate 51.

[0040] In another embodiment of the present application, in order to reduce the number of screws used in the assembly process of the heat exchanger 2, the following structural improvements are made to the assembly method of the heat exchanger 2.

[0041] A first support member 18 is provided at one side of the housing 1, and a support component 181 and a limiting component 182 are provided on the first support member 18. A threaded hole is provided at one end of the support component 181, and the limiting component 182 is located at the other end of the support component 181. One end of the first end plate 22 is fixed to the support component 181 by screws, and the other end of the first end plate 22 is located between the support component 181 and the limiting component 182. A second support member 19 is also provided in the housing 1, and a threaded hole is provided at one end of the second support member 19, a pre-installed portion is provided at one end of the second support member 19, one end of the second end plate 23 is fixed to the second support member 19 by screws, and a pre-installed fitting portion is provided at the other end of the second end plate 23, and the pre-installed portions and the pre-installed fitting portions are connected together.

[0042] Specifically, by providing a first support member 18 and a second support member 19 arranged relatively in the outer shell 1, both support members can meet the requirement that the end plate of the heat exchanger 2 is fastened by screws, and during assembly, the other end of the end plate does not need to be fixed by screws.

[0043] When installing the first end plate 22, the first end plate 22 will overlap the supporting component 181, and the first end plate 22 will be inserted into the area between the supporting component 181 and the limiting component 182, and then the first end plate 22 will be fixed to the supporting component 181 by screws.

[0044] Similarly, when installing the second end plate 23 , the second end plate 23 is preassembled with the preinstallation portion through the preinstallation matching portion, and then the second end plate 23 is fixed to the second support member 19 by screws.

[0045] After the assembly is completed and the hoisting installation is completed, the top plate 14 is turned over to the top, and the first end plate 22 can be supported by the limiting component 182 at the bottom support column. Similarly, the second end plate 23 is supported by the pre-assembled matching part and the pre-assembled part. The end plate will be further fastened by screws to improve the assembly reliability.

[0046] In this way, the number of screws used at the other end of the end plate can be reduced to improve assembly efficiency.

[0047] The supporting component 181 is a supporting rib formed on the first supporting component 18, and the supporting rib is arranged obliquely; the limiting component 182 is a limiting block provided on the first supporting component 18, and the limiting block is arranged below the supporting rib.

[0048] In some embodiments, the pre-installed portion and the pre-installed matching portion are plugged together, for example, using a tongue and a socket. Alternatively, the pre-installed portion and the pre-installed matching portion are clamped together, for example, using a claw and a slot. Alternatively, the pre-installed portion and the pre-installed matching portion are overlapped together.

[0049] In another embodiment, since the first support member 18 and the second support member 19 are arranged on both sides of the air outlet 12, the second support member 19 needs to be assembled to the front panel 15 of the housing 1, in order to improve the structural strength. The second support member 19 includes a connecting member 191 and a structural reinforcement member 192, the structural reinforcement member 192 is arranged vertically, and the connecting member 191 is arranged on the structural reinforcement member 192.

[0050] Specifically, the structural reinforcement member 192 is in a strip-shaped structure and is vertically arranged on one side of the air outlet 12 to strengthen the structural strength of the front panel 15 .

[0051] In another embodiment, the outer shell 1 is provided with first flange plates 121 arranged opposite to each other at the upper and lower parts of the air outlet 12, the outer shell 1 is provided with a second flange plate 121 at one side of the air outlet 12, and the structural reinforcement 192 is provided with a third flange plate 193 at one side of the air outlet 12, and the second flange plate 121 and the third flange plate 193 are arranged opposite to each other; the first flange plate 121, the second flange plate 121 and the third flange plate 193 extend to the outside of the air outlet 12.

[0052] Specifically, the flange plates arranged around the air outlet 12 can be connected to the indoor air duct during installation.

[0053] The third flange plate 193 provided on the structural reinforcement member 192 extends to the outside of the air outlet 12 , which not only meets the requirements for connecting the air duct, but also can further improve the overall structural strength of the structural reinforcement member 192 .

[0054] In another embodiment, one end of the first end plate 22 is fixed to the first support member 18 by screws, and the other end of the first end plate 22 is connected to the first support member 18 by a quick release structure; one end of the second end plate 23 is fixed to the second support member 19 by screws, and the other end of the second end plate 23 is connected to the second support member 19 by a quick release structure.

[0055] By arranging two relatively arranged support members in the shell 1, one end of the end plate of the heat exchanger 2 is fixedly connected to the corresponding support member by screws, while the other end of the end plate of the heat exchanger 2 is not fixed by screws and can only be limited by the support member. In this way, in the actual assembly process, when fixing the heat exchanger 2, the operator only needs to drive at least one screw into the end plates at both ends of the heat exchanger 2 to achieve fixed assembly of the heat exchanger 2, so as to reduce the use of screws and thus improve assembly efficiency.

[0056] In another embodiment of the present application, since electrical components are arranged in both the air inlet cavity and the air outlet cavity, for example, the air inlet cavity is provided with electrical components such as a fan, and the air outlet cavity is provided with electrical components such as sensors, the electrical components are connected to the cables corresponding to the circuit board 41.

[0057] Cables connected to electrical components distributed on different sides of the second mounting member from the electrical box need to pass through the second mounting member.

[0058] In actual use, in order to reduce the possibility of the second mounting member catching fire due to a cable failure, a fireproof component 40 may be provided on the second mounting member, a wiring portion 401 may be provided on the fireproof component 40, the electrical box 4 is provided on the fireproof component 40, and some cables are arranged in the air inlet cavity and the air outlet cavity via the wiring portion 401.

[0059] Specifically, for the cable to be passed through the second installation member, the cable will be led out from the electrical box 4 and will pass through the second installation member via the wiring portion 401. The cable will be supported and installed by the fireproof component 40 to reduce the impact of the cable on the second installation member.

[0060] During use, when the cable catches fire due to a fault, the cable is supported by the fireproof component 40 so that the cable will not have a significant impact on the second installation component.

[0061] The portion where the electrical box 4 is installed on the second mounting piece is fireproofed by providing a fireproof component 40, and the cable led out of the electrical box 4 and passing through the second mounting piece is installed and routed via the routing portion 401 formed on the fireproof component 40. In actual use, when a cable catches fire due to a malfunction, the cable is supported and installed by the routing portion 401 formed by the fireproof component 40 to reduce the risk of the burning cable igniting the second mounting piece. At the same time, when a fire occurs inside the electrical box 4, since the electrical box 4 is installed on the second mounting piece through the fireproof component 40, the fireproof component 40 is used to play a fireproof role, thereby providing fireproof performance for the air-conditioning indoor unit to improve the safety and reliability of use.

[0062] In one embodiment, a first notch structure is provided on the fireproof component 40, and the first notch structure forms a wiring portion 401; the first notch structure is configured to allow the cable to be inserted into the first notch structure from a notch position of the first notch structure.

[0063] Specifically, in order to facilitate the operator on site to pass the wiring harness through the second mounting part for internal wiring during the assembly process, the wiring portion 401 configured on the fire-proof component 40 is designed as a notch, that is, a first notch structure is provided on the edge of the fire-proof component 40 to form the wiring portion 401.

[0064] When the on-site operator is assembling, for the cables that need to pass through the second mounting member, the cables can be pulled into the first notch structure to complete the wiring operation without using a perforation method, which can effectively improve the assembly efficiency.

[0065] In another embodiment, in order to meet the wiring requirements of the cable passing through the second mounting component and match the first notch structure for quick assembly, a second notch structure 3401 is also provided on the second mounting component, and the second notch structure 3401 and the first notch are arranged side by side; the cable in the first notch structure also passes through the second notch structure 3401.

[0066] Specifically, the second notch structure 3401 provided on the second mounting member is arranged side by side with the first notch structure provided on the fireproof component 40 to ensure that after the cable is pulled into the first notch structure, the cable is simultaneously located in the second notch structure 3401, thereby enabling the cable to pass through the second mounting member.

[0067] In one embodiment, after the cable passes through the second mounting member and is assembled, in order to prevent the cable from escaping from the first notch structure, the cable may be limited and blocked. The specific method is as follows: like Figure 19-20 As shown, the second notch structure 3401 is further provided with an anti-detachment portion 3402 , and the anti-detachment portion 3402 is configured to restrict the cable in the second notch structure 3401 from detaching from the first notch structure.

[0068] Specifically, the second notch structure 3401 is provided with an anti-detachment portion 3402 to prevent the cable from detaching from the second notch structure 3401. The anti-detachment portion 3402 may be an elastic limiting piece or a barb or other structure provided in the second notch structure 3401. The anti-detachment portion 3402 can guide the cable to be installed into the second notch structure 3401 when the cable is assembled. After the cable is assembled in place, the anti-detachment portion 3402 is used to limit the cable from detaching from the second notch structure 3401, thereby simultaneously limiting the cable from detaching from the first notch structure.

[0069] Or, if Figure 21-22As shown, the first notch structure has a gourd-shaped opening structure.

[0070] Specifically, the opening of the first notch structure is a gourd-shaped opening structure, and the opening of the first notch structure is small when the cable is installed to prevent the cable installed in the first notch structure from escaping from the first notch structure.

[0071] In certain embodiments, such as Fig. 22 As shown, in order to more effectively reduce the risk of cables igniting the second mounting member, the notch area of ​​the second notch structure 3401 is larger than the notch area of ​​the first notch structure; the cable passing through the second notch structure 3401 does not contact the inner surface of the second notch structure 3401 .

[0072] Specifically, the first notch structure is used to support the installation of cables, while the second notch structure 3401 is used to avoid the cables. In this way, the cables can be suspended in the second notch structure 3401, thereby ensuring that the cables do not directly contact the second mounting component during use, and even if the cables catch fire, the second mounting component will not be ignited.

[0073] In some embodiments, in order to perform more effective fire prevention treatment on the second mounting member, especially to protect the second mounting member through the fireproof component 40 when a fire occurs inside the electrical box 4, a first flange 402 may be provided on the top of the fireproof component 40, and the first flange 402 covers the top of the second mounting member.

[0074] Specifically, a first flange 402 is provided on the top of the fireproof component 40, and the first flange 402 can protect the top area of ​​the second mounting component. When a fire occurs inside the electrical box 4, the rising fire is blocked by the first flange 402 to prevent the fire from affecting the second mounting component.

[0075] In order to perform fireproofing on the side of the second mounting member, a second flange 403 is provided on the side of the fireproof component 40, and the second flange 403 covers the end of the second mounting member.

[0076] Specifically, a second flange 403 is provided on the side of the fireproof component 40, and the second flange 403 can protect the side area of ​​the second mounting member, thereby reducing the impact of the flame on the side of the second mounting member through the first notch structure when a fire occurs inside the electrical box 4.

[0077] In another embodiment of the present application, for the circuit board 41 provided in the electrical box 4, during the actual design, multiple circuit boards 41 will be configured according to the specific functions of the air-conditioning indoor unit. In order to facilitate the installation of the circuit board 41 into the electrical box 4, structural improvements are made to the assembly method of the electrical box 4 and the circuit board 41.

[0078] like Fig.23 and Fig.24 As shown, the electrical box 4 also includes a mounting substrate 44, on which a pre-installation portion 441 and a locking portion 442 are provided, and the circuit board 41 is arranged on the mounting substrate 44; the electrical box 4 generally includes a box body 42 and a box cover 43, on which a pre-installation mating portion 421 and a locking mating portion 422 are provided, the pre-installation portion 441 is arranged on the pre-installation mating portion 421, and the locking portion 442 is arranged on the locking mating portion 422.

[0079] Specifically, the mounting substrate 44 is used to centrally mount the circuit boards 41 to be assembled. The circuit boards 41 are pre-assembled on the mounting substrate 44 outside the electrical box 4, and then the mounting substrate 44 is separately installed in the electrical box 4. In this way, in the actual assembly process, since the assembly of the circuit boards 41 and the mounting substrate 44 is not limited by the internal space of the electrical box 4, it is convenient for operators to quickly assemble the circuit boards 41 into the mounting substrate 44. It is only necessary to assemble the mounting substrate 44 separately in the electrical box 4 to complete the installation of multiple circuit boards 41 into the electrical box 4, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0080] There are various structures for the representation entities of the pre-installation part 441 and the pre-installation matching part 421. For example, the pre-installation part 441 is a tongue provided on the mounting substrate 44, the pre-installation matching part 421 is a positioning socket provided on the electrical box 4, and the tongue is inserted into the positioning socket. Similarly, the locking part 442 is a claw provided on the mounting substrate 44, and the locking matching part 422 is a slot provided on the electrical box 4, and the claw is stuck in the slot.

[0081] In some embodiments, in order to facilitate operators to assemble the circuit board 41 onto the mounting substrate 44 and reduce the number of screws used, the mounting substrate 44 is provided with a plurality of mounting slots 443, the edges of the mounting slots 443 are provided with clamping positioning members 444, the circuit board 41 is arranged in the corresponding mounting slots 443, the clamping positioning members 444 are clamped on the circuit board 41 and are configured to position and fix the circuit board 41 in the mounting slots 443.

[0082] Specifically, the mounting substrate 44 is provided with a mounting groove 443 for positioning the mounting circuit board 41. During assembly, the operator places the circuit board 41 into the mounting groove 443 and positions and fixes the circuit board 41 installed in the mounting groove 443 by means of a clamping positioning piece 444, so as to achieve the fixation of the circuit board 41 and reduce the use of screws or even eliminate the need for screws.

[0083] The entity of the clamping positioning member 444 can be an elastic claw, which includes an elastic part and a positioning protrusion. The positioning protrusion is arranged at the free end of the elastic part. The elastic part is set on the mounting substrate 44, and the positioning protrusion is pressed on the circuit board 41.

[0084] In another embodiment, since the circuit board 41 is assembled in the electrical box 4, the cables on the circuit board 41 need to be led out of the electrical box 4 to connect with related components. The electrical box 4 is provided with a first threading portion 423 and a second threading portion 424. The first threading portion 423 is configured to allow the cables to be led out of the electrical box 4 and arranged inside the housing, and the second threading portion 424 is configured to allow the cables to be arranged to be led out of the electrical box 4 and extend to the outside of the housing; A protection portion 445 is disposed on the mounting substrate 44 . The protection portion 445 forms a closed or semi-closed wiring channel. The wiring channel is arranged opposite to the first threading portion 423 .

[0085] Specifically, some cables of the circuit board 41 in the electrical box 4 are connected to related electrical components inside the housing, while others need to be extended to the outside of the housing for electrical connection. The first threading portion 423 needs to meet the installation requirements of internal cables, while the second threading portion 424 needs to meet the installation requirements of cables extending outside the housing.

[0086] As for the second threading portion 424, a round hole is usually used and a sealing ring is configured to meet the requirement of sealing the cable through.

[0087] As for the first threading portion 423, the cable is routed inside the shell, and a notch can be used to facilitate threading. In addition, the protective portion 445 configured on the mounting substrate 44 can use the wiring channel formed by itself inside the electrical box 4 to guide the cable to be output from the electrical box 4. At the same time, since the protective portion 445 extends from the first threading portion 423 to the inside of the electrical box 4 inside the electrical box 4, it can prevent maintenance personnel from accidentally inserting their fingers into the electrical box 4 through the first threading portion 423 and causing electric shock, thereby improving safety in use.

[0088] In another embodiment of the present application, the second mounting member 34 is formed by an integral molding method such as injection molding to form a second volute portion 342 and a second mounting portion 344. In order to improve the overall structural strength of the second mounting member 34, at least one support portion 343 is provided on the second mounting member 34, the support portion 343 protrudes from the first surface, the interior of the support portion 343 is a hollow structure, and the 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 member 34, and the first surface and the second surface are arranged in back to back; the first surface is located in the air inlet cavity, and the second surface is located in the air outlet cavity.

[0089] 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.

[0090] The fan assembly 3 needs to meet the requirements for installing the motor 31 and the fan 32 .

[0091] 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.

[0092] 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 support for the motor 31 during transportation. To this end, 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.

[0093] 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. Specifically, 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.

[0094] In 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.

[0095] At the same time, for the second mounting member 34, the fan assembly 3 is fixedly installed in the casing 1 through the second mounting member 34. The second mounting member 34 needs to meet the installation requirements of the supporting 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.

[0096] To this end, a first reinforcing rib 345 is formed on the second surface of the second mounting member 34. The first reinforcing rib 345 is 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 rib 345 can be used to improve the overall structural strength of the second mounting member 34 to meet the requirements of mounting on the housing 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.

[0097] 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.

[0098] 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.

[0099] 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 .

[0100] 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.

[0101] At the same time, 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.

[0102] 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 .

[0103] 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.

[0104] 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.

[0105] 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. 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 facing away from the first volute portion 331, and the third reinforcing rib 3421 extends along the arc direction of the second volute portion 342, and the third reinforcing rib 3421 is arranged vertically.

[0106] 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.

[0107] 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 the two adjacent second volute portions 342, and a fourth reinforcing rib 3461 is provided on the surface of the connecting portion 346 facing away from the first volute portion 331, and the fourth reinforcing rib 3461 is arranged upright.

[0108] 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.

[0109] In addition, the surface of the connecting portion 346 facing away from the first mounting member 33 is also provided with a fourth reinforcing rib 3461 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 be effectively reduced.

[0110] 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 , and the fifth reinforcing rib 3441 is arranged vertically.

[0111] Specifically, 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 .

[0112] Similarly, in order to facilitate demoulding and reduce the difficulty of processing, the fifth reinforcing rib 3441 is arranged on the surface of the second mounting portion 344 away from the first mounting member 33; and in the use state, the fifth reinforcing rib 3441 is also arranged in a vertical direction. In this way, demoulding is convenient when the mold is demoulded, and the difficulty of processing can be effectively reduced.

[0113] In another embodiment, a flange structure 347 is provided on an edge of the second mounting member 34 away from the first volute portion 331 , and a sixth reinforcing rib 3471 is provided on a surface of the flange structure 347 away from the first volute portion 331 , and the sixth reinforcing rib 3471 is arranged vertically.

[0114] 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 connection area between the second mounting member 34 and the housing 1 is increased by the flange structure 347. As a specific connection method, the flange structure 347 can be fixed to the top plate of the housing 1 by screws.

[0115] 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. Similarly, in the use state, the sixth reinforcing rib 3471 is also arranged in a vertical direction. In this way, when the mold is demoulded, demoulding is convenient and the processing difficulty can be effectively reduced.

[0116] 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 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 a vertical arrangement to meet the requirements of the structural strength reinforcement design on the functional structure part extending outward from the second mounting member 34.

[0117] Furthermore, 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.

[0118] 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; 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 .

[0119] 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.

[0120] 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.

[0124] 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.
