[0047] Some embodiments of the present disclosure provide an air conditioner.

[0048] As shown in Figures 1A and 1B, the air conditioner 1000 includes an indoor unit 100, an outdoor unit 200, and a pipeline 30. The indoor unit 100 and the outdoor unit 200 are connected by a pipeline 30 to transmit refrigerant. The indoor unit 100 includes an indoor heat exchanger (i.e., heat exchanger) 2. The outdoor unit 200 includes a compressor 201, a four-way valve 202, an outdoor heat exchanger 203, an outdoor fan 204, and an expansion valve 205. The compressor 201, the outdoor heat exchanger 203, the expansion valve 205, and the indoor heat exchanger 2, which are connected in sequence, form a refrigerant circuit. The refrigerant circulates in the refrigerant circuit and exchanges heat with the air through the outdoor heat exchanger 203 and the indoor heat exchanger 2, respectively, to achieve the cooling mode or heating mode of the air conditioner 1000.

[0049] The compressor 201 is configured to compress the refrigerant so that the low-pressure refrigerant is compressed to form a high-pressure refrigerant.

[0050] The outdoor heat exchanger 203 is configured to exchange heat between outdoor air and the refrigerant transmitted through the outdoor heat exchanger 203. For example, in the cooling mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as a condenser, so that the refrigerant compressed by the compressor 201 condenses by dissipating heat to the outdoor air through the outdoor heat exchanger 203. In the heating mode of the air conditioner 1000, the outdoor heat exchanger 203 operates as an evaporator, so that the decompressed refrigerant absorbs heat from the outdoor air through the outdoor heat exchanger 203 and evaporates.

[0051] In some embodiments, the outdoor heat exchanger 203 further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the outdoor heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0052] The outdoor fan 204 is configured to draw outdoor air into the outdoor unit 200 through the outdoor air inlet of the outdoor unit 200 and send the outdoor air after heat exchange with the outdoor heat exchanger 203 out through the outdoor air outlet of the outdoor unit 200. The outdoor fan 204 provides power for the flow of outdoor air.

[0053] Expansion valve 205 is connected between outdoor heat exchanger 203 and indoor heat exchanger 2. The opening of expansion valve 205 regulates the pressure of the refrigerant flowing through outdoor heat exchanger 203 and indoor heat exchanger 2, thereby adjusting the refrigerant flow rate between the outdoor heat exchanger 203 and indoor heat exchanger 2. The flow rate and pressure of the refrigerant flowing between the outdoor heat exchanger 203 and indoor heat exchanger 2 will affect the heat exchange performance of the outdoor heat exchanger 203 and indoor heat exchanger 2. Expansion valve 205 can be an electronic valve. The opening of expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through expansion valve 205.

[0054] The four-way valve 202 is connected to the refrigerant circuit and is configured to switch the flow direction of the refrigerant in the refrigerant circuit so that the air conditioner 1000 can perform a cooling mode or a heating mode.

[0055] The indoor heat exchanger 2 is configured to exchange heat between the indoor air and the refrigerant flowing through the indoor heat exchanger 2. For example, in the cooling mode of the air conditioner 1000, the indoor heat exchanger 2 operates as an evaporator, so that the refrigerant, after dissipating heat through the outdoor heat exchanger 203, evaporates by absorbing heat from the indoor air through the indoor heat exchanger 2. In the heating mode of the air conditioner 1000, the indoor heat exchanger 2 operates as a condenser, so that the refrigerant, after absorbing heat through the outdoor heat exchanger 203, condenses by dissipating the heat to the indoor air through the indoor heat exchanger 2.

[0056] In some embodiments, the indoor heat exchanger 2 further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the indoor heat exchanger 2, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0057] As shown in Figures 1A and 1B, the indoor unit 100 further includes an indoor fan (i.e., fan) 32. The indoor fan 32 is configured to draw indoor air into the indoor unit 100 through the indoor air inlet of the indoor unit 100 and to deliver the indoor air, after heat exchange with the indoor heat exchanger 2, through the indoor air outlet (i.e., air outlet) 12 of the indoor unit 100. The indoor fan 32 provides power for the flow of indoor air.

[0058] For ease of description, unless otherwise specified, all references to up, down, left, right, front, and back in this disclosure are based on the state of the air conditioner 1000 when in use. The side of the air conditioner 1000 facing the user when in use is the front side, and the side opposite thereto is the back side. The height of the air conditioner 1000 is the up and down direction. The left and right direction of the air conditioner 1000 is opposite to the left and right direction of the user. For example, the left side of the air conditioner 1000 is the right side of the user, and the right side of the air conditioner 1000 is the left side of the user.

[0059] Typically, an indoor unit (also known as a ducted unit) consists of a housing, a fan system, a heat exchange system, and a drainage system. The housing comprises a base plate, two side panels, a front panel, and a lower cover. To accommodate the refrigerant piping requirements of the heat exchanger, one of the two side panels is provided with a piping installation hole.

[0060] During assembly, the heat exchanger is first tilted to allow the refrigerant pipes to be inserted into the pipe mounting holes. The heat exchanger is then laid flat to secure it within the housing. However, the heat exchanger is heavy, and tilting it into the housing typically requires the collaboration of two operators, increasing assembly costs and reducing efficiency. Given this, the goal of this disclosure is to design an air conditioning technology that improves assembly efficiency.

[0061] In some embodiments, to facilitate assembly of the heat exchanger, a side panel on one side of the housing is designed as a split structure. During assembly, the side panel is attached to the housing 1 after the heat exchanger 2 is placed within the housing 1. However, in this solution, the end of the heat exchanger near the side panel lacks support, making assembly of the heat exchanger 2 still difficult.

[0062] To address the above-mentioned issues, some embodiments of the present disclosure provide an indoor unit 100. The side panels on one side of the housing 1 of the indoor unit 100 are eliminated, allowing the heat exchanger's piping to extend beyond the housing. Extensions and mounting plates are added to the sides of the housing 1 to position the piping. First and second supports are provided on either side of the housing 1 to secure the heat exchanger 2. This eliminates the need for tilting the heat exchanger 2, allowing a single person to complete assembly, reducing assembly costs and improving efficiency.

[0063] 1C to 3 , the indoor unit 100 includes a housing 1. The housing 1 includes an air inlet 11 and an air outlet 12. The air inlet 11 and the air outlet 12 may be disposed opposite to each other.

[0064] In some embodiments, the indoor unit 100 further includes a heat exchanger 2. The heat exchanger 2 is disposed in the housing 1 and is located on a side of the housing 1 close to the air outlet 12. The heat exchanger 2 is configured to exchange heat with the airflow passing therethrough to form a heat exchange airflow.

[0065] The heat exchanger 2 includes a heat exchanger body 20 and piping 21. Piping 21 is disposed on one side of the heat exchanger body 20 and is configured to communicate with the pipeline 30 to allow refrigerant in the indoor unit 10 to be transferred to and from the outdoor unit 200. For example, piping 21 is disposed on the left side of the heat exchanger body 20.

[0066] In some embodiments, the indoor unit 100 further includes a fan assembly 3. The fan assembly 3 is disposed within the housing 1 and is located on a side of the heat exchanger 2 near the air inlet 11. The fan assembly 3 is configured to drive air to flow within the housing 1, so that outside air enters the housing 1 through the air inlet 11, and is output to the outside of the housing 1 through the air outlet 12 after heat exchange in the heat exchanger 2.

[0067] In some embodiments, referring to FIG3 , the indoor unit 100 further includes an electrical box 4 . The electrical box 4 is disposed on one side (e.g., the left side) of the fan assembly 3 . The electrical box 4 is configured to couple with electrical components such as the fan assembly 3 to supply power to the fan assembly 3 and control the operation of the electrical components such as the fan assembly 3 .

[0068] In some embodiments, referring to FIG3 , the indoor unit 100 further includes a water pan 6 . The water pan 6 is located below the heat exchanger 2 to collect condensed water on the surface of the heat exchanger 2 . The water pan 6 includes a water pan body 60 and a drain pipe 61 . The drain pipe 61 is disposed on one side of the water pan body 60 and extends outside the housing 1 . The drain pipe 61 is configured to drain water collected in the water pan body 60 .

[0069] In some embodiments, the indoor unit 100 further includes a water pump assembly 5 . The water pump assembly 5 is connected to the water receiving tray 6 and is configured to discharge the water in the water receiving tray 6 to the outside of the housing 1 .

[0070] The water pump assembly 5 includes a mounting plate 51 and a water pump 52. The water pump 52 is disposed on the mounting plate 51 and assembled to the housing 1 through the mounting plate 51.

[0071] 1C and 3 , the housing 1 further comprises a bottom plate 13 and a top plate 14 . The bottom plate 13 and the top plate 14 are disposed opposite to each other.

[0072] In some embodiments, the housing 1 further includes a front panel 15. The front panel 15 is located between the bottom plate 13 and the top plate 14. The air outlet 12 can be provided on the front panel 15.

[0073] In some embodiments, the drain pipe 61 of the water receiving tray 6 can be provided on a side of the water receiving tray body 60 close to the bottom plate 13 , so as to drain the water collected in the water receiving tray body 60 under the action of gravity.

[0074] When assembling the indoor unit 100, the top plate 14 can be turned upside down first, and then the fan assembly 3, front panel 15, heat exchanger 2, water pump assembly 5, electrical box 4, water tray 6 and bottom plate 13 can be assembled in sequence.

[0075] In some embodiments, the housing 1 further includes a side panel 16. The side panel 16 may be disposed at one end of the top panel 14 to form a side wall of the housing 1. The side panel 16 is not disposed between the other end of the top panel 14 opposite the one end and the bottom panel 13 to form a mounting opening.

[0076] It is understandable that the side panel 16 can be an integral structure with the top panel 14, that is, one end of the top panel 14 is bent to form the side panel 16, or the side panel 16 and the top panel 14 are separate structures, and the side panel 16 is fixed to the top panel 14 by screws.

[0077] In this way, when assembling the heat exchanger 2 , the pipes 21 on the heat exchanger 2 do not need to be assembled by perforation, but instead extend to the outside of the shell 1 through the installation opening, and then communicate with the outdoor unit 200 .

[0078] Compared with the method in the related art in which side panels 16 are respectively arranged on both sides of the top plate 14 and holes are opened on the side panel 16 on one side for the pipe 21 to extend out, in some embodiments of the present disclosure, side panels 16 are only provided on one side of the top plate 14, while no side panels 16 are arranged on the other side of the top plate 14. In this way, the heat exchanger 2 can be assembled to the shell 1 in a horizontal posture parallel to the top plate 14, and the operator can complete the assembly of the heat exchanger 2 alone, thereby improving the assembly efficiency of the heat exchanger 2.

[0079] 3 , the bottom plate 13 includes a first plate 131 and a second plate 132 connected to each other. The first plate 131 is disposed below the water tray 6, and the second plate 132 is disposed below the fan assembly 3. This facilitates maintenance of the fan assembly 3.

[0080] In some embodiments, the second plate 132 is detachably mounted on the first plate 131. Referring to Figure 4, the first plate 131 includes a first plate body 1310 and a first engaging portion 133. The first engaging portion 133 is disposed on a side of the first plate body 1310 close to the first plate 131.

[0081] The second plate 132 includes a second plate body 1320 and a second engaging portion 134. The second engaging portion 134 is disposed on a side of the second plate body 1320 close to the first plate 131. The first engaging portion 133 cooperates with the second engaging portion 134 to achieve a detachable connection between the first plate 131 and the second plate 132.

[0082] For example, the first engaging portion 133 is a socket, and the second engaging portion 134 is a hook. The detachable connection between the first plate 131 and the second plate 132 is achieved by the mutual cooperation between the socket and the hook.

[0083] The ends of the first plate 131 and the second plate 132 close to one end of the side plate 16 can be respectively provided with folded edges so as to be fixedly connected to the side plate 16 by screws. In this way, the requirement of a screw-free design of the bottom appearance of the housing 1 can be met.

[0084] In some embodiments, the housing 1 further includes an installation space, and an opening is provided on a side away from the installation space, and the pipe extends to the outside of the housing through the installation space.

[0085] In some embodiments, referring to FIG5 , the housing 1 further includes an extension 17 . The extension 17 is disposed at the other end of the top plate 14 , i.e., at the mounting opening. The extension 17 is disposed opposite the side plate 16 and is configured to position the piping 21 during assembly of the heat exchanger 2 .

[0086] In some embodiments, referring to Figures 3 and 5 , the height of the extension 17 is less than that of the side panels 16. Thus, the extension 17 is not connected to the bottom panel 13. A mounting space 170 is formed between the partition 341, the extension 17, the bottom panel 13, and the front panel 15. The piping 21 extends outside the housing 1 through the mounting space 170.

[0087] For example, after the top panel 14 is inverted onto the work surface and the front panel 15 is mounted on the top panel 14, the heat exchanger 2 can be mounted and placed horizontally on the top panel 14. One end of the heat exchanger 2 is connected to the side panel 16, and the pipe 21 at the other end of the heat exchanger 2 extends outside the housing 1 through the mounting spacer 170.

[0088] In some embodiments, the drain pipe 61 of the water receiving tray 6 can be provided on one side of the water receiving tray body 60 near the installation space 170. In this way, the drain pipe 61 of the water receiving tray 6 can also extend to the outside of the housing 1 through the installation space 170 to facilitate the installation of the water receiving tray 6.

[0089] In some embodiments of the present disclosure, a side panel 16 is provided at one end of the top panel 14 to meet the connection requirements with the bottom panel 13, while an extension portion 17 is provided at the other end of the top panel 14. The extension portion 17 is not connected to the bottom panel 13, thereby forming an installation gap 170 between the other end of the top panel 14 and the bottom panel 13. In this way, when assembling the heat exchanger 2, the piping 21 of the heat exchanger 2 can extend through the installation gap 170. There is no need to tilt the heat exchanger 2 to complete the assembly. Instead, it can be installed flat on the top panel 14, enabling single-person assembly, thereby reducing assembly costs and improving assembly efficiency.

[0090] In some embodiments, the mounting plate 51 of the water pump assembly 5 is disposed between the extension 17 and the bottom plate 13 and covers the mounting space 170 .

[0091] In some embodiments, referring to FIG. 5 and FIG. 9 , the extension portion 17 includes an extension portion body 172 and a first limiting portion 171 . The first limiting portion 171 is disposed at a side edge of the extension portion body 172 close to the bottom plate 13 .

[0092] In some embodiments, the mounting plate 51 includes a mounting plate body 510 and a second stopper 511. The second stopper 511 is disposed on an edge of the mounting plate body 510 near the extension 17. The first stopper 171 and the second stopper 511 are butted together, and the pipe 21 is located in the space defined by the first stopper 171 and the second stopper 511.

[0093] For example, the first limiting portion 171 is a first notch groove, and the second limiting portion 511 is a second notch groove.

[0094] In this way, after the mounting plate 51 is assembled, the first limiting portion 171 and the second limiting portion 511 can cooperate with each other to effectively position the pipe 21 extending out of the housing 1 .

[0095] During assembly, after the heat exchanger 2 is placed on the top plate 14, the pipe 21 is locked in the corresponding first stop 171. Then, after the water pump assembly 5 is mounted on the top plate 14 via the mounting plate 51, the second stop 511 of the mounting plate 51 mates with the first stop 171, positioning the pipe 21 between the mounting plate 51 and the extension 17, thereby securing the pipe 21.

[0096] In some embodiments, the mounting plate 51 further includes a third stopper 512, which is disposed on an edge of the mounting plate body 510 near the water tray 6. The drain pipe 61 is disposed within the third stopper 512 and is located between the mounting plate 51 and the base plate 13. This ensures proper positioning of the drain pipe 61. For example, the third stopper 512 may be a third notch.

[0097] In some embodiments, the positioning of the pipe 21 can also be achieved through the mounting plate 51 , that is, a pipe hole is provided on the mounting plate 51 , and the pipe 21 extends to the outside of the housing 1 through the pipe hole.

[0098] During assembly, the heat exchanger 2 can be first assembled to the base plate 13, followed by the water pump assembly 5. When assembling the water pump assembly 5, the holes provided on the mounting plate 51 of the water pump assembly 5 are first aligned with the piping 21, allowing the piping 21 to be inserted into the corresponding holes. Because the water pump assembly 5 is relatively lightweight, positioning it using holes also facilitates operator adjustment.

[0099] In some embodiments, the mounting plate 51 is a split structure. Referring to FIG9 , the mounting plate body 510 includes a first mounting sub-plate 513 and a second mounting sub-plate 514. The first mounting sub-plate 513 is detachably mounted on the second mounting sub-plate 514. The second mounting sub-plate 514 is connected to at least one of the base plate 13, the front panel 15, or the fan assembly 3.

[0100] In some embodiments, the second position-limiting portion 511 is disposed on the second mounting sub-plate 514 , and the third position-limiting portion 512 is disposed on the first mounting sub-plate 513 .

[0101] In some embodiments, the water pump 52 is disposed on the first mounting sub-plate 513 to facilitate assembly and disassembly of the water pump assembly 5 .

[0102] For example, during assembly, after the heat exchanger 2 is mounted on the top plate 14, the first mounting sub-plate 513, the second mounting sub-plate 514, and the water pump 52 are first assembled together and then mounted on the top plate 14. During subsequent maintenance, only the first mounting sub-plate 513 needs to be removed from the second mounting sub-plate 514, and the water pump 52 and the first mounting sub-plate 513 can then be removed from the housing 1.

[0103] It should be noted that the detachable connection between the first mounting sub-plate 513 and the second mounting sub-plate 514 can be achieved by means of screws, buckles, etc., and the present disclosure does not impose any limitation on this.

[0104] 8 and 9 , the water pump assembly 5 further includes a pump bracket 53, which is disposed on the first mounting sub-plate 513. The water pump 52 is disposed on the pump bracket 53, thereby improving the firmness of the installation of the water pump 52 and the convenience of assembly.

[0105] For example, the pump bracket 53 has a cantilever structure and is disposed on the inner surface of the first mounting sub-plate 513. The pump bracket 53 allows the water pump 52 to be suspended on one side of the first mounting sub-plate 513 near the heat exchanger 2.

[0106] In some embodiments, the water pump assembly 5 further includes an extension bracket 54 . The extension bracket 54 is disposed at an end of the pump frame 53 away from the mounting plate 51 and extends toward the water receiving tray 6 .

[0107] In some embodiments, the water pump assembly 5 further includes a water level sensor 55 , which is disposed at one end (eg, the lower end) of the extension bracket 54 close to the water receiving tray 6 .

[0108] In this way, the water pump 52 and the water level sensor 55 are assembled centrally 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, thereby realizing the integrated design of the water pump assembly 5 and further improving the assembly efficiency of the indoor unit 100.

[0109] In some embodiments of the present disclosure, a split mounting plate 51 is used to support and install the water pump 52. 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, while the second mounting sub-plate 514 is still set on the shell 1 to meet the requirements of the overall installation of the shell 1. In this way, the shell 1 only needs to be equipped with a side plate 16 on one side, without having to set side plates 16 on both sides and make holes to meet the installation requirements of the water pump 52, which reduces the number of parts and improves assembly efficiency.

[0110] In other embodiments of the present disclosure, for indoor units 100 that do not require active drainage, gravity drainage can be achieved through the drain pipe 61 on the water tray 6, eliminating the need for a water pump 52 on the mounting plate 51. If the water pump 52 is not installed, a water level sensor 55 can be installed on the mounting plate 51 as needed to monitor the water level in the water tray 6. Of course, to save costs, the water level sensor 55 can also be omitted from the mounting plate 51.

[0111] In some embodiments of the present disclosure, the following improvements are made to the structures of the heat exchanger 2 and the shell 1 to improve the assembly efficiency of the heat exchanger 2.

[0112] 3 , the heat exchanger 2 further includes a first end plate 22 and a second end plate 23. The first end plate 22 and the second end plate 23 are respectively located at opposite ends of the heat exchanger body 20 along the length direction. For example, the first end plate 22 is located on the left side of the heat exchanger body 20, and the second end plate 23 is located on the right side of the heat exchanger body 20.

[0113] 3 and 5 , the heat exchanger 2 further includes a refrigerant coil 24 , which is disposed within the heat exchanger body 20 and between the first end plate 22 and the second end plate 23 . The refrigerant coil 24 is connected to the pipe 21 .

[0114] 5 and 6 , the housing 1 further includes a first support member 18, which is disposed on a side of the side plate 16 close to the heat exchanger 2 and the air outlet 12. The first support member 18 is configured to support and fix one side (eg, the left side) of the heat exchanger 2.

[0115] Referring to Figure 6 , the first support member 18 includes a first support member body 180 and a first mating portion 181. The first mating portion 181 is disposed on a side of the first support member body 180 that is proximal to the heat exchanger 2. Along the height direction of the housing 1 (the vertical direction as shown in Figure 6 ), the end of the first mating portion 181 that is proximal to the base plate 13 extends obliquely away from the air outlet 12. A threaded hole is provided at the end (e.g., the bottom end) of the first mating portion 181 that is distal to the air outlet 12.

[0116] In some embodiments, the first support member 18 further includes a fourth limiting portion 182. The fourth limiting portion 182 is located at the other end of the first matching portion 181, which is closer to the top plate 14. The fourth limiting portion 182 is spaced apart from the first matching portion 181 in a direction perpendicular to the extension direction of the first matching portion 181 (or perpendicular to the first matching portion 181).

[0117] In some embodiments, the first support member 18 further includes a fifth limiting portion 183. The fifth limiting portion 183 is disposed on a side of the first matching portion 181 close to the air outlet 12 and is configured to support the heat exchanger body 2. In some embodiments, the first end plate 22 is disposed on the first support member 18. Referring to Figures 5 and 6, one end (such as the bottom end) of the first end plate 22 is fixed to the first matching portion 181 by screws, and one end (such as the top end) of the first end plate 22 is passed between the first matching portion 181 and the fourth limiting portion 182 and abuts against the first support member body 180. The heat exchanger body 2 abuts against the fifth limiting portion 183.

[0118] 5 and 7 , the housing 1 further includes a second support member 19. The second support member 19 is disposed on the other side of the housing 1 opposite the side panel 16. One end of the second support member 19 can be fixed to the front panel 15. A threaded hole is provided at one end of the second support member 19 (e.g., the bottom end) away from the air outlet 12, and a first pre-installed portion is provided at the other end of the second support member 19 (e.g., the top end) closer to the air outlet 12.

[0119] In some embodiments, the second end plate 23 is mounted on the first support member 18. One end (e.g., the bottom end) of the second end plate 23 is fixed to the second support member 19 via screws. The other end (e.g., the top end) of the second end plate 23 is provided with a seventh mating portion. The seventh mating portion mates with the first pre-installed portion to secure the second end plate 23 to the second support member 19.

[0120] In this way, one end of the first end plate 22 is fixed to the first support member 18 by screws, while the other end of the first end plate 22 is connected to the first support member 18 using a quick-release mechanism. One end of the second end plate 23 is fixed to the second support member 19 by screws, while the other end of the second end plate 23 is connected to the second support member 19 using a quick-release mechanism. This completes the assembly of the heat exchanger 2 and the housing 1.

[0121] In some embodiments of the present disclosure, a first support member 18 and a second support member 19 are disposed opposite each other in the housing 1. During assembly, one end (e.g., the bottom end) of the first end plate 22 and the second end plate 23 of the heat exchanger 2 are fastened to the first support member 18 and the second support member 19, respectively, using screws. The other ends (e.g., the top end) of the first end plate 22 and the second end plate 23 do not need to be fastened to the housing 1 using screws and can simply be engaged with the support members.

[0122] Thus, during the assembly process, the operator can fix the heat exchanger 2 by only screwing one screw into each of the first end plate 22 and the second end plate 23 at both ends of the heat exchanger 2 to achieve the fixed assembly of the heat exchanger 2 and the housing 1. This reduces the number of screws used in the assembly of the heat exchanger 2, simplifies the assembly steps, and improves assembly efficiency.

[0123] For example, when installing the first end plate 22, the first end plate 22 will overlap the first matching portion 181 and be inserted into the area between the first matching portion 181 and the fourth limiting portion 182. Then, the first end plate 22 is fixed to the first matching portion 181 by screws.

[0124] Similarly, when installing the second end plate 23, the second end plate 23 is first preassembled together with the first pre-installed portion through the seventh matching portion, and then fixed to the second support member 19 by screws.

[0125] After the indoor unit 100 is assembled, it is flipped over. At this point, the top plate 14 is flipped from the bottom to the top. Referring to Figure 5 , the top of the first end plate 22 is supported by the fourth stopper 182. Similarly, the top of the second end plate 23 is supported by the seventh mating portion pre-assembled with the first pre-assembly portion. The bottom ends of the first and second end plates 22, 23 are further fastened with screws to enhance the reliability of the heat exchanger 2 assembly.

[0126] In some embodiments, the first engaging portion 181 can be a support rib formed on the first support member body 180, which is arranged along the height direction of the housing 1 and tilted away from the air outlet 12. The fourth limiting portion 182 can be a stopper provided on the first support member body 18, which is arranged near the bottom plate 13 (e.g., below the bottom) of the support rib. The fifth limiting portion 183 can also be a stopper, with at least one side of the stopper extending perpendicular to the extension direction of the first engaging portion 181 to support the heat exchanger body 20 during assembly.

[0127] It should be noted that the first pre-installation portion and the seventh mating portion can be plugged together, for example, using a tongue and a socket, or the first pre-installation portion and the seventh mating portion can be snapped together, for example, using a claw and a slot, or the first pre-installation portion and the seventh mating portion can be overlapped. This disclosure does not impose any restrictions on this.

[0128] In some embodiments, since the first support member 18 and the second support member 19 are arranged on both sides of the air outlet 12 , one side of the second support member 19 needs to be assembled to the front panel 15 to improve the structural strength of the second support member 19 itself.

[0129] 5 , the second support member 19 includes a first connection member 192. The first connection member 192 is vertically arranged along the height direction of the indoor unit 100.

[0130] For example, the first connecting member 192 is in a strip-shaped structure and is vertically arranged on one side (such as the right side) of the air outlet 12 to strengthen the structural strength of the connection between the second supporting member 19 and the front panel 15 .

[0131] 5 , the second support member 19 further includes a second connecting member 191. The second connecting member 191 is connected to the first connecting member 192 and extends toward the heat exchanger 2. The first pre-installed portion may be provided at one end of the second connecting member 191 near the front panel 15 and the top panel 14.

[0132] In some embodiments, referring to FIG5 , the housing 1 further includes at least one first flange plate 121. For example, the housing 1 includes two first flange plates 121. The two first flange plates 121 are arranged opposite each other along the height direction of the air outlet 12. For example, the two first flange plates 121 are located at the top and bottom of the air outlet 12, respectively.

[0133] In some embodiments, the housing 1 further includes a second flange plate 122 , which is disposed on one side (eg, the left side) of the air outlet 12 in the longitudinal direction.

[0134] 5 and 7 , the second support member 19 further includes a third flange plate 193. The third flange plate 193 is arranged opposite the second flange plate 122 along the length of the air outlet 12. For example, the third flange plate 193 can be disposed on the other side (e.g., the right side) of the air outlet 12 in the length direction, and the third flange plate 193 can be connected to the first connecting member 192.

[0135] 7 , the third flange plate 193 can be integrally formed with the first connector 192. This not only improves the stability of the connection between the third flange plate 193 and the first connector 192, but also simplifies the installation steps and improves assembly efficiency.

[0136] It can be understood that the first flange plate 121, the second flange plate 122 and the third flange plate 193 arranged around the air outlet 12 can extend to the outside of the air outlet 12, that is, the side away from the heat exchanger 2, so as to be connected to the indoor air duct during installation, so that the indoor unit 100 can supply air to the room through the air duct.

[0137] In addition, it should be noted that in some embodiments of the present disclosure, the third flange plate 193 is configured to be connected to the first connecting member 192 and extend to the outside of the air outlet 12, which can meet the requirements of connecting with the air duct and further improve the overall structural strength of the second support member 19.

[0138] In some embodiments, the electrical box 4 is disposed at the end of the partition 341 away from the side panel 16 (i.e., near the extension 17). Referring to Figures 10 and 11 , the electrical box 4 includes at least one circuit board 41. Multiple cables are connected to the circuit board 41. These cables couple the circuit board 41 to electrical components such as the fan assembly 3 and the water pump assembly 5.

[0139] In some embodiments, the electrical box 4 further includes a box body 42 and a box cover 43. The box body 42 and the box cover 43 form a first accommodating cavity, and the circuit board 41 can be disposed in the first accommodating cavity.

[0140] It should be noted that, during design, multiple circuit boards 41 may be configured in the electrical box 4 according to the different functions of the components in the indoor unit 100 .

[0141] In some embodiments, the electrical box 4 further includes a mounting substrate 44, and the circuit board 41 can be disposed on one side of the mounting substrate 44. The mounting substrate 44 is configured to centrally mount the circuit boards 41 to be assembled.

[0142] For example, when assembling the electrical box 4 , the circuit board 41 can be pre-assembled on the mounting substrate 44 outside the electrical box 4 and then integrally installed into the electrical box 4 .

[0143] In this way, the circuit board 41 and the mounting substrate 44 are no longer restricted by the internal space of the electrical box 4 when they are assembled. It is only necessary to assemble the mounting substrate 44 separately in the electrical box 4, and multiple circuit boards 41 can be installed in the electrical box 4, thereby reducing the difficulty of assembly and making it convenient for operators to quickly assemble the circuit boards 41 into the mounting substrate 44, which is beneficial to improving the assembly efficiency of the electrical box 4.

[0144] In some embodiments, referring to Figures 3 and 10 , the mounting substrate 44 includes a mounting substrate body 440 and a second pre-installed portion 441. For example, the second pre-installed portion 441 is disposed on a side of the mounting substrate body 440 that is adjacent to the top plate 14. The box body 42 includes a box body 420 and a sixth mating portion 421. The sixth mating portion 421 is disposed on a side of the box body 420 that is adjacent to the top plate 14 and corresponds to the second pre-installed portion 441.

[0145] In some embodiments, the mounting base 44 further includes a locking portion 442. The locking portion 442 is disposed on a side of the mounting base body 440 that is adjacent to the bottom plate 13. Correspondingly, the box body 42 further includes a fourth mating portion 422. The fourth mating portion 422 is also disposed on a side of the box body 420 that is adjacent to the bottom plate 13 and corresponds to the locking portion 442.

[0146] In this way, the second pre-installation portion 441 cooperates with the sixth matching portion 421 , and the locking portion 442 cooperates with the fourth matching portion 422 , thereby achieving assembly of the mounting substrate 44 and the box body 42 .

[0147] It should be noted that the second pre-installation portion 441 may be a tongue provided on the mounting substrate 44, and the sixth mating portion 421 may be a positioning socket provided on the electrical box 4, into which the tongue is inserted. The locking portion 442 may be a claw provided on the mounting substrate 44, and the fourth mating portion 422 may be a slot provided on the electrical box 4, into which the claw is engaged. This disclosure is not limited to this.

[0148] 11 , the mounting substrate 44 further includes at least one mounting groove 443. The circuit board 41 is disposed in the corresponding mounting groove 443. The mounting groove 443 is configured to position and mount the circuit board 41.

[0149] In some embodiments, the mounting substrate 44 further includes a second positioning portion 444. The second positioning portion 444 is disposed at the edge of the mounting slot 443. The second positioning portion 444 engages with the circuit board 41 and is configured to secure the circuit board 41 within the mounting slot 443. This improves the reliability of the mounting between the circuit board 41 and the mounting substrate 44, prevents the circuit board 41 from moving within the mounting slot 443, and reduces the number of screws used, thereby improving assembly efficiency.

[0150] During assembly, the operator can first place the circuit board 41 into the mounting groove 443, and then use the second positioning portion 444 to limit and fix the circuit board 41 in the mounting groove 443. In this way, the number of screws used is reduced or even eliminated, making it easier to assemble the circuit board 41.

[0151] It should be noted that the second positioning portion 444 may be an elastic claw. The elastic claw may include an elastic portion and a positioning protrusion, with the positioning protrusion disposed at the free end of the elastic portion, while the elastic portion is disposed on the mounting substrate 44. The positioning protrusion can press the circuit board 41 to engage the circuit board 41 in the mounting slot 443.

[0152] It is understandable that, 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 couple with electrical components such as the fan assembly 3 and the water pump assembly 5 .

[0153] It should be noted that part of the cables in the circuit board 41 need to be coupled with the relevant electrical components inside the shell 1, and another part of the cables in the circuit board 41 need to extend to the outside of the shell 1 and couple with the relevant electrical components outside the shell 1.

[0154] 1C , 10 and 11 , the electrical box 4 further includes a first threading portion 423 . The first threading portion 423 is disposed on one side (e.g., the left side) of the box body 420 . The first threading portion 423 is configured to allow cables to be led out of the electrical box 4 and arranged inside the housing 1 .

[0155] In some embodiments, the electrical box 4 further includes a second threading portion 424. The second threading portion 424 is disposed on the other side (eg, the rear side) of the box body 420. The second threading portion 424 is configured to allow cables to be drawn out of the electrical box 4 and extended to the outside of the housing 1.

[0156] It is understandable that the first threading portion 423 can meet the installation requirement of the cable extending into the interior of the housing 1, while the second threading portion 424 can meet the installation requirement of the cable extending to the outside of the housing 1.

[0157] In some embodiments, referring to Figures 10 and 11 , the mounting base plate 44 further includes a protective portion 445. The protective portion 445 forms a closed or semi-closed wiring channel. The wiring channel is arranged opposite the first wiring portion 423 and extends along the first wiring portion 423 toward the interior of the electrical box 4. Within the electrical box 4, the cables of the circuit board 41 can pass through the wiring channel formed by the protective portion 445 and pass through the first wiring portion 423 to exit the electrical box 4.

[0158] In this way, it is possible to 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 the reliability of the electrical box 4.

[0159] It should be noted that the first wire threading portion 423 may be in the form of a notch, so that the cable can pass through from the inside of the electrical box 4 to the inside of the housing 1 for wiring.

[0160] In some embodiments, the second threading portion 424 can be in the form of a round hole and configured with a sealing ring to meet the requirement of sealing the cable out, thereby improving the reliability of the electrical box 4.

[0161] The structure of the fan assembly 3 is described below.

[0162] 12 to 14 , the fan assembly 3 includes a motor 31 and a fan 32. The motor 31 is coupled to the fan 32 to drive the fan 32 to rotate, thereby allowing air outside the housing 1 to enter the interior of the housing 1 through the air inlet 11 and be further discharged from the air outlet 12 via the heat exchanger 2.

[0163] In some embodiments, referring to Figures 14 to 17 , the fan assembly 3 further includes a mounting assembly, which includes a first mounting member 33 and a second mounting member 34. The first mounting member 33 is detachably mounted on the second mounting member 34. A second accommodating cavity is formed between the first mounting member 33 and the second mounting member 34 to accommodate the motor 31 and the fan 32.

[0164] 15 , the first mounting member 33 includes at least one first volute portion 331 and at least one first fixing portion 332. When the first mounting member 33 includes one first volute portion 331, the first fixing portion 332 may be located on one side of the first volute portion 331. When the first mounting member 33 includes multiple first volute portions 331, the first fixing portion 332 may be located between any two adjacent first volute portions 331.

[0165] 16 and 17 , the second mounting member 34 includes at least one second volute portion 342 and at least one second fixing portion 344. The second fixing portion 344 is disposed opposite to the first fixing portion 332, and the second volute portion 342 is disposed opposite to the first volute portion 331.

[0166] It is understandable that the first fixing portion 332 and the second fixing portion 344 can cooperate with each other to meet the requirements for fixing and installing the motor 31. The first volute portion 331 and the second volute portion 342 can cooperate with each other to meet the requirements for fixing and installing the fan 32.

[0167] For example, a fixed mounting area is formed between the first fixing portion 332 and the second fixing portion 344, and the motor 31 is disposed within the fixed mounting area. A volute cavity is formed between the first volute portion 331 and the corresponding second volute portion 342, and the fan 32 is disposed within the corresponding volute cavity. In this case, the motor 31 is configured to drive the fan 32 to rotate within the volute cavity.

[0168] 15 and 16 , the first mounting member 33 further includes at least one clamping portion 333 . The clamping portion 333 may be disposed at both ends of the first mounting member 33 in the longitudinal direction.

[0169] For example, the first mounting member 33 includes two first volute portions 331 and four clamping portions 333. Two clamping portions 333 are respectively provided on one side of the two first volute portions 331 away from each other, and the two clamping portions are respectively located at both ends of the corresponding first volute portion 331 in the width direction (the front-to-back direction as shown in FIG20 ).

[0170] In some embodiments, the second mounting member 34 further includes a third mating portion 348. The third mating portion 348 is disposed on the second volute portion 342 at a position opposite to the third mating portion 348. The engaging portion 333 and the third mating portion 348 are engaged with each other to allow the first mounting member 33 and the second mounting member 34 to be detachably connected.

[0171] It should be noted that the entities expressing the engaging portion 333 and the third matching portion 348 may be, for example, a claw and a slot, or a snap-fit ​​structure, etc., and the present disclosure does not impose any limitation on this.

[0172] In some embodiments, the first mounting member 33 further includes at least one first positioning portion 334. For example, the first mounting member 33 further includes two first positioning portions 334. The two first positioning portions 334 can be disposed on the same side (e.g., the left side) of any two first volute portions 331.

[0173] In some embodiments, the second mounting member 34 further includes a second mating portion 349. The first positioning portion 334 and the second mating portion 349 are connected together to limit the position of the first mounting member 33 during the connection process between the first mounting member 33 and the second mounting member 34, thereby improving the assembly efficiency of the first mounting member 33 and the second mounting member 34.

[0174] In this way, pre-assembling the first mounting member 33 and the second mounting member 34 together by snapping together can reduce the number of screws used, which is conducive to simplifying the assembly steps of the first mounting member 33 and the second mounting member 34, thereby improving the overall assembly efficiency of the indoor unit 100.

[0175] In some embodiments, referring to Figures 14 and 15 , the first fixing portion 332 includes two first frames 3321 and a reinforcing portion 3322. The two first frames 3321 are arranged side by side. For example, the first frames 3321 have an arc-shaped structure to match the shape of the motor 31. The reinforcing portion 3322 is disposed on a side of the first frames 3321 away from the second mounting member 34 and extends along the curved direction of the first frames 3321.

[0176] 16 , the second fixing portion 344 includes two second frames 3442 , which are disposed opposite to each other along the length direction of the partition 341 . Surfaces of the second frames 3442 facing the first frame 3321 are formed with mounting grooves.

[0177] The first frame 3321 and the second frame 3442 can be fixed together by screws, and the end of the motor 31 is fixed in the corresponding mounting groove between the first frame 3321 and the second frame 3442 to achieve the fastening of the motor 31 by the first fixing part 332 and the second fixing part 344.

[0178] In some embodiments of the present disclosure, after the first mounting member 33 and the second mounting member 34 are snap-fitted together, the first frame 3321 and the second frame 3442 can be further fastened together using screws. This improves the connection reliability between the first frame 3321 and the second frame 3442, thereby further enhancing the support effect for the motor 31 and the fan 32.

[0179] In some embodiments, referring to Figures 16 and 17 , the housing 1 further includes a partition 341. The partition 341 is disposed within the housing 1 and divides the interior of the housing 1 into an air inlet cavity 110 and an air outlet cavity 120. The air inlet 11 communicates with the air inlet cavity 110, and the air outlet 12 communicates with the air outlet cavity 120.

[0180] In some embodiments, the second mounting member 34 and the partition 341 are integrally formed, and the partition 341 is a part of the second mounting member 34. In this way, the installation steps are reduced, and the second mounting member 34 and the partition 341 can be installed in the housing 1 as a whole, which is conducive to improving assembly efficiency.

[0181] It should be noted that the partition 341 can also be a separate component. After the partition 341 is installed in the housing 1, the second mounting member 34 can be disposed on the first surface of the partition 341. This disclosure uses the example of the second mounting member 34 and the partition 341 being integrally formed as an example.

[0182] The heat exchanger 2 is located in the air outlet cavity 120 and is arranged on the top of the water receiving tray 6. The at least one second volute portion 342 and the at least one second fixing portion 344 are respectively provided on the first surface of the partition portion 341 close to the air inlet 11.

[0183] In some embodiments, the second mounting member 34 further includes at least one through-hole 3410, which is formed in the partition 341 and is disposed opposite the volute cavity. The through-hole 3410 communicates with the corresponding volute cavity and is configured to direct the airflow generated by the fan 32 toward the heat exchanger 2. Thus, when the fan 32 rotates within the volute cavity, air outside the volute cavity is drawn into the volute cavity and discharged through the through-hole 3410.

[0184] For example, 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 110 in the shell 1 from the air inlet 11, and then can be driven by the fan 32 to enter the air outlet cavity 120 from the through-port 3410 to exchange heat with the heat exchanger 2, and the gas after heat exchange is finally output to the outside from the air outlet 12.

[0185] It should be noted that the second volute portion 342 , the second fixing portion 344 and the partition portion 341 may be integrally formed by injection molding or the like to form the second mounting member 34 .

[0186] Thus, during the assembly of the fan assembly 3, the second mounting member 34 can be first fixed to the flipped top plate 14, the motor 31 can then be placed in the second fixing portion 344 of the second mounting member 34, and the fan 32 can be placed in the first volute portion 331 of the second mounting member 34. Finally, the first mounting member 33 can be assembled to the second mounting member 34.

[0187] At this time, the motor 31 is fixedly installed between the first fixing portion 332 and the second fixing portion 344. The fan 32 is installed between the first volute portion 331 and the second volute portion 342.

[0188] It is understood that during use, the motor 31 is fixedly suspended on the second fixing portion 344 via the first fixing portion 332, and the second fixing portion 344 needs to bear the weight of the motor 31. Due to the large weight of the motor 31, the second fixing portion 344 needs to meet the support requirements for the motor 31 during transportation and use of the indoor unit 100.

[0189] In some embodiments, referring to FIG. 16 , the second mounting member 34 further includes at least one third support member 343 . The third support member 343 is located on the first surface of the partition 341 and is disposed opposite the second fixing portion 344 . The third support member 343 is configured to provide sufficient strength support for the second fixing portion 344 . The second fixing portion 344 can be fixed to the partition 341 via the third support member 343 , thereby improving the structural strength of the connection between the second fixing portion 344 and the partition 341 and ensuring that the second fixing portion 344 can reliably support the motor 31 .

[0190] In some embodiments, the third support member 343 protrudes from the first surface of the partition 341, and a hollow structure is formed between the third support member 343 and the partition 341. This not only effectively increases the overall structural strength of the connection between the partition 341 and the third support member 343, but also reduces production costs.

[0191] In some embodiments, referring to FIG14 , because the motor 31 exerts a downward pulling force on the second fixing portion 344 when in use, the third support member 343 is arranged to extend along the height direction of the partition 341 (the vertical direction as shown in FIG16 ). Thus, when in use, the third support member 343 is also arranged upright, effectively increasing the structural strength of the connection between the second fixing portion 344 and the partition 341 along the height direction of the partition 341, thereby improving the support effect on the motor 31.

[0192] It is understandable that since the motor 31 and the fan 32 are fixedly mounted in the housing 1 via the second mounting member 34 during assembly and use, the second mounting member 34 as a whole needs to have sufficient bearing capacity to meet the installation requirements of the motor 31 and the fan 32.

[0193] 17 , the second mounting member 34 further includes a plurality of first reinforcing ribs 345 , which are staggeredly disposed on the second surface of the partition 341 near the air outlet 12 , thereby improving the overall structural strength of the partition 341 .

[0194] It should be noted that the first surface and the second surface are arranged in opposite directions. The first surface is located in the air inlet cavity 110 , and the second surface is located in the air outlet cavity 120 .

[0195] In some embodiments of the present disclosure, a first reinforcing rib 345 is provided on the second surface of the partition 341. On the one hand, the overall structural strength of the partition 341 can be improved so that after the second mounting member 34 is installed in the shell 1, the installation requirements of the motor 31, the fan 32 and the first mounting member 33 can be met.

[0196] On the other hand, by arranging the first reinforcing rib 345 on the side opposite to the second volute portion 342, the third support member 343 and the second fixing portion 344, the partition portion 341 can effectively simplify the structure of the first surface while meeting the installation requirements, thereby reducing the processing difficulty of the second mounting member 34.

[0197] 16 , the second mounting member 34 further includes at least one second reinforcing rib 3431 disposed within the hollow structure of the third support member 343. The provision of the second reinforcing rib 3431 can further enhance the structural strength of the third support member 343.

[0198] In some embodiments, the third support member 343 is further provided with an opening 3432, which is located at the end of the third support member 343 facing away from the first mounting member 33. The second reinforcing rib 3431 also extends in the height direction of the second mounting member 34 within the hollow structure of the third support member 343. This facilitates the removal of the mold from the opening 3432 for the second mounting member 34 manufactured by injection molding, thereby reducing the difficulty of manufacturing.

[0199] In some embodiments, during use, the second volute portion 342 is located at the top of the first volute portion 331, and the second volute portion 342 extends from the first surface of the partition portion 341 toward a direction away from the first surface and close to the free end of the first volute portion 331 away from the first surface to form an arc surface.

[0200] 16 , the second mounting member 34 further includes a third reinforcing rib 3421 disposed on an outer surface of the second volute portion 342 facing away from the first volute portion 331 . The third reinforcing rib 3421 is configured to increase the structural strength of the second volute portion 342 .

[0201] In some embodiments, the third reinforcing rib 3421 extends along the curvature of the outer surface of the second volute portion 342. When in use, the third reinforcing rib 3421 is arranged vertically along the height of the second mounting member 34. This facilitates mold release and reduces processing difficulty.

[0202] It can be understood that one end of the second fixing portion 344 and one end of the second volute portion 342 are respectively connected to the first surface of the partition portion 341, while the other end of the second fixing portion 344 and the other end of the second volute portion 342 are extended in a direction away from the first surface.

[0203] In some embodiments, referring to FIG16 , the second mounting member 34 further includes a third connecting member 346. The third connecting member 346 is disposed at an end of the second fixing portion 344 away from the first surface. If the second mounting member 34 includes multiple second volute portions 342, both ends of the third connecting member 346 can be connected to two adjacent second volute portions 342, respectively, to enhance the structural strength between the second fixing portion 344 and the two adjacent second volute portions 342.

[0204] In some embodiments, the second mounting member 34 further includes a fourth reinforcing rib 3461 disposed on the surface of the third connecting member 346 facing away from the first mounting member 33. The fourth reinforcing rib 3461 is configured to enhance the structural strength of the third connecting member 346. Furthermore, the fourth reinforcing rib 3461 is arranged in an upright position, facilitating mold release and reducing manufacturing complexity.

[0205] In some embodiments, the second mounting member 34 further includes a fifth reinforcing rib 3441. The fifth reinforcing rib 3441 is disposed on the surface of the second fixing portion 344 facing away from the first mounting member 33 to enhance the structural strength of the second fixing portion 344, thereby improving the bearing capacity of the motor 31. Furthermore, the fifth reinforcing rib 3441 is arranged in an upright position, facilitating demolding and reducing processing difficulty.

[0206] In some embodiments, referring to Figures 14 and 16 , the second mounting member 34 further includes a flange structure 347. The flange structure 347 is disposed on an edge of the partition 341 away from the first mounting member 33, i.e., at an end near the top plate 14. The flange structure 347 can extend in a direction away from the first surface of the partition 341. This facilitates connection of the second mounting member 34 to the housing 1.

[0207] It is understood that the second mounting member 34 is connected between the bottom plate 13 and the top plate 14 of the housing 1. When the second mounting member 34 is connected to the top plate 14, the flange structure 347 can be used to increase the contact area between the second mounting member 34 and the housing 1. For example, the flange structure 347 can be fixed to the top plate of the housing 1 by screws.

[0208] In some embodiments, the second mounting member 34 further includes a sixth reinforcing rib 3471 disposed on the surface of the flange structure 347 facing away from the first volute portion 331, and the sixth reinforcing rib 3471 is arranged vertically. This further enhances the structural strength of the flange structure 347, facilitates demolding, and effectively reduces manufacturing difficulty.

[0209] In summary, in some embodiments of the present disclosure, a first reinforcing rib 345, a second reinforcing rib 3431, a third reinforcing rib 3421, a fourth reinforcing rib 3461, a fifth reinforcing rib 3441 and a sixth reinforcing rib 3471 are provided on the second mounting member 34, which can further improve the structural strength of the second mounting member 34 to meet the installation requirements of the motor 31 and the fan 32.

[0210] In addition, the first reinforcing rib 345, 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 arranged in an upright position (i.e., along the height direction of the shell 1), which facilitates smooth demoulding and can simplify the structure of the mold to reduce processing difficulty.

[0211] It should be noted that the first fixing portion 332 and the first volute portion 331 can be fixedly connected. In this way, during installation, the first mounting member 33 can be mounted as a whole on the second mounting member 34. The first fixing portion 332 and the first volute portion 331 can also be provided separately. In this way, during installation, the first fixing portion 332 and the first volute portion 331 can be mounted separately on the second mounting member 34.

[0212] In the case where the first fixing portion 332 is independently provided, the independently provided first fixing portion 332 may be configured as a fixing bracket 35 as described below.

[0213] In other embodiments, referring to FIG. 18 to FIG. 24 , the fan assembly 3 includes a motor 31 , a fan 32 , a first mounting member 33 , a second mounting member 34 and a fixing bracket 35 .

[0214] It should be noted that the arrangement of the second mounting member 34 is similar to that of the above embodiment and will not be described in detail here. The difference between this embodiment and the above embodiment is that the fan assembly 3 uses an independently configured fixing bracket 35 to cooperate with the second fixing portion 344 of the second mounting member 34 to achieve the installation and fixation of the motor 31.

[0215] 19 and 20 , the first mounting member 33 is detachably mounted on the second mounting member 34. The first mounting member 33 includes a plurality of first volute portions 331.

[0216] The fixing bracket 35 may be arranged between two first mounting members 33 . Alternatively, when a plurality of first volute portions 331 are arranged on the same first mounting member 33 , the fixing bracket 35 may be arranged between two adjacent first volute portions 331 on the first mounting member 33 .

[0217] The fixing bracket 35 is detachably mounted on the second mounting member 34, forming a fixed mounting area with the second fixing portion 344. The motor 31 is disposed in the fixed mounting area. A volute cavity is formed between the first volute portion 331 and the corresponding second volute portion 342. The volute cavity is connected to the corresponding through-port 3410. The fan 32 is disposed in the corresponding volute cavity, and the motor 31 is configured to drive the fan 32 to rotate within the volute cavity.

[0218] In some embodiments, referring to FIG22 , the fixing bracket 35 has a frame structure and includes a first sub-fixing portion 351, a second sub-fixing portion 352, and two clamping portions 353. The first sub-fixing portion 351 and the second sub-fixing portion 352 are fixedly connected to the second mounting member 34, and the clamping portion 353 is connected between the first sub-fixing portion 351 and the second sub-fixing portion 352.

[0219] Referring to Figure 21 , the second fixing portion 344 includes two second brackets 3442, which are arranged opposite each other along the length of the partition 341. A clamp groove is formed on the surface of the second brackets 3442 that faces the clamp portion 353. The end of the motor 31 is fixed between the corresponding clamp portion 353 and the clamp groove of the second bracket 3442.

[0220] During the assembly process of the motor 31, the motor 31 is installed between the fixing bracket 35 and the second fixing part 344. The clamp part 353 formed by the fixing bracket 35 and the second frame 3442 formed by the second fixing part 344 will clamp the corresponding ends of the motor 31 so that the motor 31 is fastened to the fixing bracket 35 and the second fixing part 344.

[0221] It is understandable that, due to the heavy weight of the motor 31, in order to improve the connection reliability between the clamp portion 353 and the second frame 3442, the fixing bracket 35 can be fixed to the second mounting member 34 by screws to improve the connection reliability of the mounting portion of the motor 31.

[0222] In other embodiments, referring to FIG22 , the fixing bracket 35 further includes an inserting portion 354, which is disposed on the first sub-fixing portion 351 and extends in a direction away from the second sub-fixing portion 352. Referring to FIG19 , the second mounting member 34 further includes a fifth mating portion 3433, which is disposed on an end of the third support member 343 that is adjacent to the first mounting member 33.

[0223] The plug-in portion 354 and the fifth matching portion 3433 are plugged together, and the second sub-fixing portion 352 is fixed to the second mounting member 34 by screws. In this way, the use of screws is saved and the assembly efficiency is improved.

[0224] During assembly of the motor 31, the motor 31 is first placed between the two second brackets 3442 of the second mounting member 34. The plug-in portion 354 of the fixing bracket 35 is then inserted into the fifth mating portion 3433 formed on the third support member 343. The fixing bracket 35 is then flipped over so that the second sub-fixing portion 352 rests against the third connecting member 346. The second sub-fixing portion 352 and the third connecting member 346 are then fastened together using screws.

[0225] It should be noted that when the fixing bracket 35 is used to securely mount the motor 31, the second mounting member 34 may also be configured with the second reinforcing ribs 3431, third reinforcing ribs 3421, fourth reinforcing ribs 3461, fifth reinforcing ribs 3441, and sixth reinforcing ribs 3471 on the corresponding structures to enhance the overall structural strength of the second mounting member 34. When the indoor unit 100 is in the suspended mounting position, the second reinforcing ribs 3431, third reinforcing ribs 3421, fourth reinforcing ribs 3461, fifth reinforcing ribs 3441, and sixth reinforcing ribs 3471 are all arranged upright to facilitate demolding.

[0226] In some embodiments, referring to FIG. 19 , the fan assembly 3 further includes a support shaft 36 , which is connected to the rotating shaft of the motor 31 to achieve power transmission, and the fan 32 is disposed on the support shaft 36 .

[0227] In some embodiments, the fan assembly 3 further includes a bearing 37. For example, when multiple fans 32 are configured on the same support shaft 36, the adjacent multiple fans 32 are connected together through the support shaft 36. One end of the support shaft 36 can be connected to the rotating shaft of the motor 31 through a coupling, while the other end of the support shaft 36 needs to be supported by the bearing 37 to ensure that the support shaft 36 can drive the two fans 32 to rotate smoothly in their respective volutes.

[0228] 18 to 20 , the first fixing portion 33 further includes at least one first mounting bracket 335 disposed at one end of the first volute portion 331. The second mounting member 34 further includes at least one second mounting bracket 340. The bearing 37 is located between the first mounting bracket 335 and the second mounting bracket 340.

[0229] For example, during assembly, the motor 31 and the fan 32 are placed at corresponding positions on the second mounting member 34, and the bearing 37 disposed 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 to 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.

[0230] It is understandable that by connecting the first mounting bracket 335 and the second mounting bracket 340 together and fixing the bearing 37 therebetween, there is no need to configure additional components to separately install the bearing 37, thereby reducing the number of parts and components and improving assembly efficiency.

[0231] In some embodiments, the fan assembly 3 further includes a shock absorbing portion 38, which is disposed between the first mounting bracket 335 and the second mounting bracket 340. For example, the shock absorbing portion 38 may be an annular structure and sleeved on the bearing 37. The bearing 37 is fixedly mounted between the first mounting bracket 335 and the second mounting bracket 340 via the shock absorbing portion 38.

[0232] It should be noted that the provision of the shock-absorbing portion 38 can improve the installation reliability of the bearing 37 and extend the service life of the bearing 37 , and can also reduce the noise generated by the vibration of the bearing 37 during the operation of the fan assembly 3 .

[0233] It is understood that during use, the motor 31 drives the fan 32 via the support shaft 36. The vibration generated by the fan 32 during the air supply process may be transmitted to the bearing 37 via the support shaft 36. A shock absorber 38 is provided on the outside of the bearing 37 and is clamped between the first mounting bracket 335 and the second mounting bracket 340. This can buffer the vibration generated by the bearing 37, thereby reducing noise and extending the service life of the bearing 37.

[0234] 23 , the shock absorber 38 includes a shock absorber body 380 and a sixth stopper 381. The sixth stopper 381 extends toward the exterior of the shock absorber body 380. The second mounting bracket 340 is provided with a stopper slot into which the sixth stopper 381 can be inserted, facilitating assembly of the shock absorber 38.

[0235] During on-site assembly, the operator first inserts the sixth limiting portion 381 of the shock absorbing portion 38 into the limiting groove to pre-assemble the shock absorbing portion 38 onto the second mounting bracket 340. The operator then secures the first mounting bracket 335 to the second mounting member 34. This allows the shock absorbing portion 38 to be precisely clamped between the first mounting bracket 335 and the second mounting bracket 340, ensuring accurate installation of the bearing 37.

[0236] In some embodiments of the present disclosure, electrical components are disposed in both the air inlet cavity 110 and the air outlet cavity 120. For example, the air inlet cavity 110 is provided with electrical components such as the motor 31, while the air outlet cavity 120 is provided with electrical components such as the water pump assembly 5. The electrical components need to be connected to corresponding cables in the circuit board 41 of the electrical box 4.

[0237] In some embodiments, the electrical box 4 is disposed in the air inlet cavity 110. If the electrical components and the electrical box 4 are located on different sides of the partition 341 (for example, in the air outlet cavity 120), the cables connecting the electrical components and the electrical box 4 need to pass through the partition 341.

[0238] 25 and 26 , the indoor unit 100 further includes a fireproofing member 40. The fireproofing member 40 is disposed on a side of the partition 341 near the electrical box 4. The electrical box 4 is connected to the partition 341 via the fireproofing member 40. This prevents the partition 341 from catching fire due to a cable malfunction during use.

[0239] In some embodiments, a wiring portion 401 is provided on the fire protection portion 40 , and the cables between the electrical box 4 and the electrical components can be arranged in the air inlet cavity 110 and the air outlet cavity 120 via the wiring portion 401 .

[0240] For example, for a cable to pass through the partition 341, the cable will be drawn out from the electrical box 4 and will pass through the partition 341 via the wiring portion 401. The cable will be installed with the support of the fireproof portion 40 to reduce the impact of the cable on the partition 341.

[0241] During use, when the cable catches fire due to a fault, the cable is supported only by the fireproof portion 40 and does not contact the partition 341 , thereby reducing the impact on the partition 341 .

[0242] In this way, the fireproof part 40 is provided to perform fireproof treatment on the portion where the electrical box 4 is connected to the partition 341, and the cable led out of the electrical box 4 and passing through the partition 341 is installed and routed through the routing part 401 formed by the fireproof part 40, thereby improving the fireproof performance and reliability of the indoor unit 100.

[0243] In some embodiments, a first notch is provided on the fireproof portion 40, and the first notch forms a wiring portion 401. The first notch is configured to allow a cable to be installed into the air outlet cavity 120 through the notch position of the first notch.

[0244] In this way, the wiring portion 401 configured on the fire protection portion 40 is designed to be a notch, that is, a first notch is set on the edge of the fire protection portion 40 to form the wiring portion 401, which makes it easier for operators to pass the wiring harness through the partition portion 341 for wiring during the assembly process.

[0245] For example, when the operator is assembling on site, for cables that need to pass through the partition 341, the cables can be pulled into the first gap to complete the wiring operation without using a perforation method, thereby effectively improving assembly efficiency.

[0246] In some embodiments, referring to Figures 27 and 28 , the partition 341 further includes a second notch 3401, which is arranged side by side with the first notch. This allows cables in the first notch to pass through the second notch 3401, ensuring that the cables meet the wiring requirements of the partition 341 while improving assembly efficiency.

[0247] The second notch 3401 provided on the partition 341 is arranged side by side with the first notch provided on the fireproof part 40 to ensure that after the cable is pulled into the first notch, it is located in the second notch 3401 , thereby enabling the cable to pass through the partition 341 .

[0248] 19 and 26 , the partition 341 further includes an anti-detachment portion 3402 disposed in the second notch 3401. The anti-detachment portion 3402 is configured to prevent the cable in the second notch 3401 from detaching from the first notch.

[0249] For example, the anti-slip portion 3402 can be an elastic stopper or a barb disposed in the second notch 3401. The anti-slip portion 3402 can guide the cable into the second notch 3401 during assembly. After the cable passes through the partition 341 and is assembled, the anti-slip portion 3402 can also prevent the cable from escaping from the second notch 3401, thereby further preventing the cable from escaping from the first notch.

[0250] In some embodiments, as shown in Figure 28, the first notch can have a gourd-shaped opening structure. The height of the opening at the entrance of the first notch is smaller than the height of the inner shape of the first notch, thereby preventing the cable inserted into the first notch from escaping from the first notch.

[0251] In some embodiments, as shown in FIG28 , the second notch 3401 has a larger area than the first notch, so that the cable passing through the second notch 3401 does not contact the inner surface of the second notch 3401. This can further prevent the cable from igniting the partition 341.

[0252] It is understood that the first notch is used to support the installation of cables, while the second notch 3401 is used to avoid the cables. In this way, the cables can be suspended in the second notch 3401, thereby ensuring that the cables do not come into contact with the partition 341 during use, and even if the cables catch fire, the partition 341 will not be ignited.

[0253] 26 , the fireproof portion 40 includes a body portion 400 and a first flange 402, which is disposed on the top of the body portion 400. The first flange 402 covers the top of the partition 341, thereby protecting the top area of ​​the partition 341.

[0254] In this way, the fire prevention effect of the fireproof part 40 and the protection effect of the partition 341 can be further improved. In particular, when a fire occurs inside the electrical box 4, the rising fire can be blocked by the first flange 402 to reduce the impact of the fire on the partition 341.

[0255] In some embodiments, the fireproof portion 40 further includes a second flange 403, which is provided on a side of the main body 400. The second flange 403 covers the end of the partition 341, thereby providing a fireproof effect on the side of the partition 341.

[0256] In this way, when a fire occurs inside the electrical appliance box 4 , the second flange 403 can prevent the flame from affecting the side of the partition 341 through the first notch.

[0257] Those skilled in the art will understand that the scope of the present invention is not limited to the above specific embodiments, and that certain elements of the embodiments may be modified and replaced without departing from the spirit of the present application. The scope of the present application is limited by the appended claims.
