[0040] Some embodiments of the present disclosure provide an air conditioner.

[0041] As shown in FIG. 1A and FIG. 1B , the air conditioner 2000 includes an outdoor unit 20 .

[0042] In some embodiments, the air conditioner 2000 further includes an indoor unit 10. The indoor unit 10 is connected to the outdoor unit 20.

[0043] In some embodiments, the air conditioner 2000 further includes a pipe 30. The indoor unit 10 and the outdoor unit 20 are connected via the pipe 30 to transmit refrigerant.

[0044] In some embodiments, the outdoor unit 20 includes a compressor 201. The compressor 201 is configured to compress refrigerant so that low-pressure refrigerant is compressed to form high-pressure refrigerant.

[0045] In some embodiments, the outdoor unit 20 further includes a first heat exchanger 203 (outdoor heat exchanger). The first heat exchanger 203 is configured to perform heat exchange between outdoor air and the refrigerant transmitted in the first heat exchanger 203. For example, in the cooling mode of the air conditioner 2000, the first heat exchanger 203 operates as a condenser, so that the refrigerant compressed by the compressor 201 dissipates heat to the outdoor air through the first heat exchanger 203 and condenses. In the heating mode of the air conditioner 2000, the first heat exchanger 203 operates as an evaporator, so that the decompressed refrigerant absorbs heat from the outdoor air through the first heat exchanger 203 and evaporates.

[0046] In some embodiments, the first heat exchanger 203 further includes heat exchange fins to expand the contact area between the outdoor air and the refrigerant transmitted in the first heat exchanger 203, thereby improving the heat exchange efficiency between the outdoor air and the refrigerant.

[0047] In some embodiments, the outdoor unit 20 further includes a first fan 204. The first fan 204 is configured to draw outdoor air into the outdoor unit 20 through the outdoor air inlet of the outdoor unit 20, and to deliver the outdoor air, after heat exchange with the first heat exchanger 203, through the outdoor air outlet of the outdoor unit 20. The first fan 204 provides power for the flow of outdoor air.

[0048] In some embodiments, the indoor unit 10 includes a second heat exchanger 21 (i.e., a heat exchanger). The second heat exchanger 21 is configured to exchange heat between the indoor air and the refrigerant transmitted through the second heat exchanger 21. For example, in the cooling mode of the air conditioner 2000, the second heat exchanger 21 operates as an evaporator, so that the refrigerant, after dissipating heat through the first heat exchanger 203, absorbs heat from the indoor air through the second heat exchanger 21 and evaporates. In the heating mode of the air conditioner 2000, the second heat exchanger 21 operates as a condenser, so that the refrigerant, after absorbing heat through the first heat exchanger 203, dissipates heat to the indoor air through the second heat exchanger 21 and condenses.

[0049] In some embodiments, the second heat exchanger 21 further includes heat exchange fins to expand the contact area between the indoor air and the refrigerant transmitted in the second heat exchanger 21, thereby improving the heat exchange efficiency between the indoor air and the refrigerant.

[0050] As shown in Figures 1A and 1B, the indoor unit 10 further includes a second fan 3 (i.e., a blower). The second fan 3 is configured to draw indoor air into the indoor unit 10 through the indoor air inlet of the indoor unit 10 and to deliver the indoor air, after heat exchange with the second heat exchanger 21, through the air outlet 12 of the indoor unit 10. The second fan 3 provides power for the flow of indoor air.

[0051] In some embodiments, the compressor 201, the first heat exchanger 203, the expansion valve 205 and the second heat exchanger 21 connected in sequence form a refrigerant circuit, in which the refrigerant circulates and exchanges heat with the air through the first heat exchanger 203 and the second heat exchanger 21 respectively to realize the cooling mode or heating mode of the air conditioner 2000.

[0052] In some embodiments, the outdoor unit 20 further includes an expansion valve 205. The expansion valve 205 is connected between the first heat exchanger 203 and the second heat exchanger 21. The opening of the expansion valve 205 regulates the pressure of the refrigerant flowing through the first and second heat exchangers 203 and 21, thereby adjusting the refrigerant flow rate between the first and second heat exchangers 203 and 21. The flow rate and pressure of the refrigerant flowing between the first and second heat exchangers 203 and 21 affect the heat exchange performance of the first and second heat exchangers 203 and 21. The expansion valve 205 can be an electronic valve. The opening of the expansion valve 205 is adjustable to control the flow rate and pressure of the refrigerant flowing through the expansion valve 205.

[0053] In some embodiments, the outdoor unit 20 further includes a four-way valve 202. 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 2000 operates in cooling mode or heating mode.

[0054] Duct unit is the abbreviation of concealed air conditioner. Duct unit solves the problem of wall-mounted units and cabinet units being exposed outside and affecting the appearance. At the same time, the duct length is longer than that of ordinary household air conditioners, and the installation is more flexible. It is an emerging type of air conditioner.

[0055] Typically, a ducted air conditioner consists of a housing and components such as a heat exchanger and fan mounted within it. The heat exchanger is mounted on a water inlet, while the fan and electrical control box are located on one side of the heat exchanger. During assembly, the heat exchanger, fan, and other components must be separately installed within the housing. Limited internal space within the housing makes assembly difficult for operators, resulting in low assembly efficiency for the ducted air conditioner 1000.

[0056] To solve the above problems, some embodiments of the present disclosure provide a duct air conditioner 1000. The duct air conditioner 1000 also includes a mounting frame. The fan and the electrical control box are arranged on the mounting frame. Before assembling the fan and the electrical control assembly on the mounting frame, the fan and the electrical control assembly are first installed on the mounting frame respectively to form a pre-assembled assembly. In addition, the water receiving tray is provided with a first mounting portion, and the shell is provided with a first plug-in portion. The first mounting portion cooperates with the first plug-in portion to assemble the heat exchange assembly to the shell. The mounting frame is provided with a second mounting portion, and the shell is provided with a second plug-in portion. The second mounting portion cooperates with the second plug-in portion to assemble the pre-assembled assembly to the shell. In this way, the assembly of the duct air conditioner 1000 is completed, and the assembly efficiency is improved.

[0057] 1C and 2 , ducted air conditioner 1000 includes a housing 1. Housing 1 includes a first cavity (accommodating cavity) configured to house components such as a heat exchange assembly, a fan, and an electronic control assembly. Housing 1 protects the components within the first cavity.

[0058] In some embodiments, the housing 1 further includes an air inlet 11. In FIG. 1C and FIG. 2, the air inlet 11 may be located at the bottom of the housing 1. Air flow may enter the housing 1 through the air inlet 11 for heat exchange.

[0059] In some embodiments, the housing 1 further includes an air outlet 12 . In FIG. 1C and FIG. 2 , the air outlet 12 may be located at the top of the housing 1 , and the airflow after heat exchange may flow out through the air outlet 12 .

[0060] In some embodiments, the air inlet 11 and the air outlet 12 are disposed opposite each other. For example, the air inlet 11 is disposed at the top of the housing 1, and the air outlet 12 is disposed at the bottom of the housing 1. Alternatively, the air inlet 11 is disposed at the bottom of the housing 1, and the air outlet 12 is disposed at the top of the housing 1.

[0061] 1C and 3 , the duct unit 1000 further includes a heat exchange assembly 2 disposed within the housing 1. The heat exchange assembly 2 is configured to exchange heat with the airflow entering the housing 1 to heat or cool the airflow.

[0062] In some embodiments, the heat exchange assembly 2 includes a heat exchanger 21 , which is configured to perform heat exchange on an airflow flowing therethrough to form a heat exchange airflow.

[0063] Since the heat exchanger 21 may generate condensed water or defrosted water during use, the heat exchange assembly 2 further includes a water receiving pan 22, which is arranged on one side (below) of the heat exchanger 21 to collect water generated on the surface of the heat exchanger 21. Here, the water may include the aforementioned condensed water and defrosted water.

[0064] 1C and 3 , the water tray 22 includes a water tray body 220 and a drain port 222. The drain port 222 connects the water tray body 220 with the exterior of the housing 1. During use, water flowing from the surface of the heat exchanger 21 flows into the water tray body 220 and is discharged through the drain port 222 and a drain pipe connected to the drain port 222.

[0065] To ensure that the water in the water tray body 220 can be drained smoothly, in some embodiments, the water tray body 220 is configured to be tilted toward the drain port 222 so that the water in the water tray body 220 flows to the drain port 222 .

[0066] In some embodiments, referring to Figures 3 and 5 , the ducted air conditioner 1000 further includes a fan 3. The fan 3 is disposed within the housing 1. For example, the fan 3 is spaced apart from the heat exchange assembly 2 in the height direction of the housing 1, and the fan 3 is disposed below the heat exchange assembly 2. The fan 3 is configured to drive air flow, so that the air enters the housing 1 through the air inlet 11 to exchange heat with the heat exchanger 21, and the air after heat exchange is discharged through the air outlet 12.

[0067] In some embodiments, referring to Figures 3 and 5 , the duct air conditioner 1000 further includes an electronic control assembly 4. The electronic control assembly 4 is disposed within the housing 1. The electronic control assembly 4 is configured to couple to an external power supply to supply power to the electrical components of the duct air conditioner 1000 (e.g., the fan 3 ). The electronic control assembly 4 is also configured to control the operating status of the electrical components of the duct air conditioner 1000.

[0068] 3 and 8 , the electric control assembly 4 includes an electric control box 41 , which is fixedly disposed in the housing 1 . The electric control box 41 includes a second cavity (installation cavity) configured to accommodate a circuit board 42 .

[0069] In some embodiments, the electrical control assembly 4 further includes at least one circuit board 42, which is disposed in the second cavity of the electrical control box 41, so that the circuit board 42 is mounted in the housing 1 via the electrical control box 41. The circuit board 42 is configured to supply power to the electrical components of the duct air conditioner 1000 and control the operating status of the electrical components of the duct air conditioner 1000.

[0070] It should be noted that the number of circuit boards 42 can be configured according to the functions of the duct machine 1000 .

[0071] In some embodiments, referring to FIG5 , to facilitate installation of the heat exchange assembly 2, the water tray 22 further includes first mounting portions 221 (first mounting rails), which are disposed on both sides of the water tray body 220. The housing 1 further includes first plug-in portions 18 (first bearing slots), which cooperate with the first mounting portions 221 to assemble the heat exchange assembly 2 within the housing 1, thereby improving assembly efficiency of the heat exchange assembly 2.

[0072] In some embodiments, the first mounting portion 221 is inserted into the first plugging portion 18. For example, the first mounting portion 221 is a slide rail and the first plugging portion 18 is a slot; or the first mounting portion 221 is a slot and the first plugging portion 18 is a slide rail.

[0073] In this way, when the heat exchange component 2 is installed in the shell 1, the first mounting parts 221 on both sides of the water receiving tray body 220 can be aligned with the first plug-in parts 18 and inserted into the corresponding first plug-in parts 18 to complete the assembly of the heat exchange component 2 and the shell 1.

[0074] 3 and 5 , in some embodiments, to facilitate installation of the fan 3 and electronic control assembly 4 and improve assembly reliability and convenience, the duct air conditioner 1000 further includes a mounting bracket 13, which is fixedly disposed within the housing 1. The fan 3 and electronic control box 41 are disposed on the mounting bracket 13 and arranged on a side of the mounting bracket 13 away from the air outlet 12. For example, the fan 3 and electronic control box 41 may be disposed on the lower side of the mounting bracket 13.

[0075] Before assembling the fan 3 and the electronic control assembly 4 on the mounting frame 13 , the fan 3 and the electronic control assembly 4 are firstly mounted on the mounting frame 13 respectively to form a pre-assembled assembly.

[0076] In this way, after the mounting frame 13, the fan 3 and the electronic control component 4 are pre-assembled together outside the shell 1, they are assembled and fixed in the shell 1 through the mounting frame 13, so that the fan 3 and the electronic control component 4 can be assembled into the shell 1 together to improve the assembly efficiency.

[0077] In some embodiments, in order to facilitate the assembly of the pre-assembled components and the housing 1 , the mounting bracket 13 can be assembled in the housing 1 in an insertion manner.

[0078] In some embodiments, referring to FIG. 5 , the mounting bracket 13 includes a mounting bracket body 130 .

[0079] In some embodiments, the mounting bracket 13 further includes a second mounting portion 134 (second mounting rail), and the second mounting portion 134 is disposed on both sides of the mounting bracket body 130 .

[0080] 5 , the housing 1 includes a second plug-in portion 17 (second bearing slot). The second mounting portion 134 cooperates with the second plug-in portion 17 to achieve assembly of the mounting bracket 13 and the housing 1.

[0081] In some embodiments, the mounting bracket 13 is inserted into the second plugging portion 17 via the second mounting portion 134. For example, the second mounting portion 134 is a slide rail and the second plugging portion 17 is a slot; or the second mounting portion 134 is a slot and the second plugging portion 17 is a slide rail.

[0082] Thus, during the assembly process, the mounting frame 13, equipped with the fan 3 and the electronic control assembly 4, is inserted into the second plug-in portion 17 through the second mounting portion 134, thereby assembling the pre-assembled assembly with the housing 1. The second plug-in portion 17 not only provides support for the mounting frame 13, but also allows the mounting frame 13 to be positioned and fixed.

[0083] In some embodiments, referring to FIG. 3 , the housing 1 further includes a support frame 15 (supporting frame).

[0084] In some embodiments, the housing 1 further includes a plurality of mounting plates 16 (protective plates), and the mounting plates 16 are detachably connected to the support frame 15 , and the support frame 15 supports the mounting plates 16 .

[0085] For example, two oppositely arranged mounting plates 16 among the multiple mounting plates 16 are respectively provided with a first plug-in portion 18 and a second plug-in portion 17, the water receiving tray 22 is inserted into the two oppositely arranged first plug-in portions 18, and the mounting frame 13 is inserted between the two oppositely arranged second plug-in portions 17.

[0086] When assembling the housing 1, the plurality of mounting plates 16 are fixed to the support frame 15. For example, the mounting plate 16 having the first plug-in portion 18 and the second plug-in portion 17 is first fixed to the mounting frame 15. The mounting frame 13 is then inserted between the two second plug-in portions 17, the water tray 22 is inserted between the two first plug-in portions 18, and the remaining mounting plates 16 are then assembled.

[0087] 3 and 4 , the housing 1 further includes a first plate 161 (enclosing plate), which is disposed on a side of the support frame 15. For example, the first plate 161 includes a first sub-side plate, a second sub-side plate, and a third sub-side plate adjacent to each other.

[0088] In some embodiments, the housing 1 further includes at least one third plate 163 (access panel), which is detachably connected to the first plate 161. For example, the third plate 163 is detachably connected to the first sub-side plate and the third sub-side plate for easy disassembly.

[0089] For example, the first plate 161 has a U-shaped cross-section, and the opposing inner sidewalls of the first plate 161 are respectively provided with two opposing first plug-in portions 18, and the opposing inner sidewalls of the first plate 161 are also respectively provided with two opposing second plug-in portions 17. The third plate 163 is detachably provided at the open end of the first plate 161.

[0090] In some embodiments, the housing 1 further includes a second plate 162 (end plate). The second plate 162 is detachably disposed at a first end (eg, top end) of the first plate 161.

[0091] In some embodiments, an air inlet 11 is provided at the first end (such as the top end) of the shell 1, and an air outlet 12 is provided at the second end (such as the bottom end) of the shell 1. The air outlet 12 is located on the side where the second plate 162 is located.

[0092] The first plate 161 and the third plate 163 are wrapped around the outside of the mounting frame 15. During assembly, the first plate 161 is first connected to the mounting frame 15, and then the heat exchange component 2 and the pre-assembled component are respectively inserted into the corresponding plug-in parts. The third plate 163 is then connected to one side of the first plate 161, and the second plate 162 is set at the first end of the first plate 161 to complete the assembly of the duct machine 1000.

[0093] In some embodiments, to facilitate maintenance of the duct unit 1000 by operators, referring to FIG4 , the third plate 163 includes a first sub-plate 1631 (first plate body) and a second sub-plate 1632 (second plate body). The first sub-plate 1631 and the second sub-plate 1632 are respectively detachably connected to the first plate 161. The first sub-plate 1631 is arranged on one side of the pre-assembled assembly, and the second sub-plate 1632 is arranged on one side of the heat exchange assembly 2. The first sub-plate 1631 and the second sub-plate 1632 are butted together.

[0094] Thus, the third plate 163 adopts a split structure, with the first sub-plate 1631 used to meet the maintenance and disassembly requirements of the fan 3 and the electrical control box, and the second sub-plate 1632 used to meet the maintenance and disassembly requirements of the heat exchange assembly 2. In this way, during the maintenance process, targeted disassembly and assembly can be carried out to reduce the difficulty of maintenance.

[0095] Of course, the third plate 163 may also be an integrated structure, which is convenient for installation and can improve assembly efficiency.

[0096] In some embodiments, the third plate 163 further includes a third sub-plate 1633 (refrigerant plate), which is detachably mounted on the first plate 161. The third sub-plate 1633 includes a first hollow portion 16331 (first hollow structure), through which the refrigerant pipe of the heat exchanger 21 passes.

[0097] In some embodiments, the third plate 163 further includes a fourth sub-plate 1634 (drain plate), which is detachably mounted on the first plate 161. The fourth sub-plate 1634 is provided with a second hollow portion 16341 (second hollow structure), in which the drain pipe of the water receiving tray 22 is located.

[0098] In some embodiments, the second sub-board 1632 includes a first notch portion 16321 (first notch), and the third sub-board 1633 is located in the first notch portion 16321 .

[0099] In some embodiments, the second sub-board 1632 further includes a second notch portion 16322 (second notch), and the fourth sub-board 1634 is located in the second notch portion 16322 .

[0100] It is understood that the refrigerant pipe of the heat exchange assembly 2 needs to be connected to the external outdoor unit 20, and the drain pipe of the water receiving pan 22 also needs to extend outside the housing 1. By providing the first notch 16321 and the second notch 16322 at corresponding positions on the second sub-plate 1632, the third sub-plate 1633 and the fourth sub-plate 1634 are avoided. In this way, when the heat exchange assembly 2 needs to be repaired, it will not be affected by the refrigerant pipe and the drain pipe, thereby reducing the difficulty of maintenance.

[0101] In some embodiments, referring to FIG9 , mounting bracket 13 further includes mounting surface 131 (mounting support surface), to which fan 3 and electrical control assembly 4 are respectively fixedly mounted. Mounting bracket 13 is disposed behind housing 1, with electrical control box 41 and fan 3 located between mounting bracket 13 and heat exchange assembly 2.

[0102] It is understandable that the mounting frame 13 is disposed in the housing 1 , and the electric control box 41 is disposed on a side of the mounting frame 13 where the mounting surface 131 is located. The electric control box 41 cooperates with the mounting surface 131 to form a second cavity.

[0103] In some embodiments, the mounting frame 13 further includes a vent 132, which is disposed on the mounting surface 131. The fan 3 is connected to the air outlet 12 through the vent 132. In this way, the requirement that the fan 3 drives the air flow is met.

[0104] 8 and 9 , the outlet of the fan 3 is connected to the vent 132. After the fan 3 is started, air flows into the housing 1 through the air inlet 11, exchanges heat with the heat exchanger 21 in the heat exchange assembly 2, and then flows into the fan 3. The air is then output from the vent 132 and then delivered to the outside of the housing 1 through the air outlet 12.

[0105] 9 , to facilitate installation of the fan 3 , the mounting bracket 13 further includes a third plug-in portion 133 (installation slot) disposed on the mounting surface 131 and located on both sides of the vent 132 . The volute 31 is inserted into the third plug-in portion 133 .

[0106] In this way, the fixed installation of the fan 3 and the mounting frame 13 is facilitated, and the reliability of the connection between the volute 31 and the mounting frame 13 can be improved.

[0107] In some embodiments, in order to improve the heat dissipation efficiency of the circuit board 42 in the electric control box 41 , referring to FIG. 5 , the mounting frame 13 further includes a partition 136 , which is arranged at the air outlet 12 and located on a side of the mounting frame 13 away from the fan 3 .

[0108] In some embodiments, the housing 1 further includes a cavity 19 (heat dissipation cavity) formed between the partition 136, the mounting frame 13, and the housing 1. The cavity 19 is located on the side where the electronic control component 4 is located to facilitate heat dissipation of the electronic control component 4.

[0109] It is understood that by providing a partition 136 on the mounting frame 13, the interior space of the housing 1 can be divided into two relatively independent cavities through the mounting frame 13. The fan 3, heat exchange component 2, and electronic control component 4 are placed in the cavity on one side (e.g., the lower side) of the mounting frame 13, while the partition 136 is placed in the cavity on the other side (e.g., the upper side) of the mounting frame 13. The cavity 19 is formed between the partition 136 and the housing 1, which facilitates heat dissipation in the lower cavity.

[0110] In some embodiments, the partition 136 includes a first ventilation portion 137 , which is connected to the cavity 19 .

[0111] In some embodiments, the electric control box 41 includes a second ventilation portion, and the first ventilation portion 137 is connected to the second ventilation portion through the cavity 19 .

[0112] In some embodiments, the electric control box 41 includes a third ventilation portion, which is located outside the cavity 19 .

[0113] It should be noted that the structures and functions of the second ventilation part and the third ventilation part are similar to those of the first ventilation part, and will not be described in detail here.

[0114] During use, after the fan 3 is started, the airflow output from the outlet of the fan 3 will flow toward the air outlet 12. During this process, a portion of the airflow will flow through the partition 136 and finally be output from the air outlet 12.

[0115] Because the air pressure at the outlet of the fan 3 is greater than the air pressure in the cavity 19, another portion of the air can enter the cavity 19 through the first ventilation portion 137 of the partition 136. The air in the cavity 19 then enters the electrical control box 41 through the second ventilation portion, exchanges heat with the circuit board 42, and then flows out through the third ventilation portion.

[0116] When the fan 3 is in operation, the air around the electric control box 41 is sucked into the fan 3 , so that the air in the electric control box 41 flows out through the third ventilation portion, and the air in the cavity 19 flows into the electric control box 41 from the second ventilation portion.

[0117] 3 , by forming a relatively independent cavity 19 in the housing 1 , a portion of the airflow generated by the fan 3 during operation enters the cavity 19 through the first ventilation portion 137 under the action of air pressure to dissipate heat from the circuit board 42 .

[0118] After entering cavity 19, the airflow increases the air pressure within cavity 19. Because fan 3 absorbs ambient air during operation, the air pressure around electrical control box 41, located within the same cavity as fan 3, decreases. This allows the airflow entering cavity 19 to enter electrical control box 41, remove heat, and then exit from electrical control box 41 and reenter fan 3 during operation. This cycle improves the heat dissipation efficiency of circuit board 42 within electrical control box 41.

[0119] In some embodiments, the mounting bracket 13 further includes a mounting opening 135 , and the electric control box 41 is fixed to the mounting bracket body 130 through the mounting opening 135 .

[0120] 5 and 8 , the electric control box 41 includes a box body 411 , in which the circuit board 42 is disposed. The box body 411 is disposed on the mounting bracket 13 and is located outside the cavity 19 .

[0121] The electric control box 41 further includes a first cover 412 . The first cover 412 is detachably disposed on the box body 411 and is located outside the cavity 19 .

[0122] 5 , the electrical control box 41 further includes a second cover 414 (maintenance cover), which is disposed on the mounting bracket 13 and is located within the cavity 19. The second cover 414 is detachably connected to the box body 411, allowing for easy removal of the second cover 414 to access the circuit board 42 within the electrical control box 41.

[0123] The box body 411 and the second cover 414 cover the installation opening 135. The box body 411 is provided with a third ventilation portion 402, and the second cover 414 is provided with a second ventilation portion.

[0124] For the electric control box 41, the circuit board 42 is installed through the box body 411, and the box body 411 is arranged around the installation opening 135. One side of the box body 411 is covered by the first cover 412, and the second cover 414 covers the other side of the installation opening 135 to form a relatively closed electric control box 41.

[0125] In some embodiments, referring to FIG. 5 , the second cover 414 includes a first sub-cover 4141 (cover plate), and the first sub-cover 4141 includes a maintenance port.

[0126] 5 , the second cover 414 further includes a second sub-cover 4142 (maintenance panel), which is detachably mounted on the maintenance port. A second vent can be mounted on at least one of the first sub-cover 4141 and the second sub-cover 4142 .

[0127] In this way, the second cover 414 is set as a split structure, and the easily damaged components are set in the circuit board 42 corresponding to the maintenance opening of the first sub-cover 4141. When maintenance is needed, only the second sub-cover 4142 needs to be removed for maintenance, which can further facilitate later maintenance.

[0128] In some embodiments, in order to further improve the heat dissipation efficiency of the circuit board 42 in the electrical control box 41, referring to Figure 9, the electrical control component 4 also includes a heat dissipation part 43, which is thermally connected to the circuit board 42. The heat dissipation part 43 is configured to conduct the heat generated by the circuit board 42 to the outside of the electrical control box 41 and perform heat dissipation with the help of the airflow generated by the fan 3.

[0129] For example, a heat dissipation channel is formed between the electric control box 41 and the fan 3. The heat dissipation portion 43 passes through the electric control box 41 and is thermally connected to the circuit board 42. The portion of the heat dissipation portion 43 extending outside the electric control box 41 is located in the heat dissipation channel.

[0130] In some embodiments, the electric control box 41 further includes a heat dissipation port 4113 , which can be provided on the box body 411 . The heat dissipation portion 43 is inserted into the heat dissipation port 4113 and is thermally connected to the circuit board 42 .

[0131] The circuit board 42 generates heat during operation, and therefore, it is necessary to perform heat dissipation treatment on the circuit board 42. A heat dissipation portion 43 is provided in the electric control box 41, so that the heat dissipation portion 43 can be utilized to perform heat dissipation treatment on the circuit board 42.

[0132] The heat dissipation channel formed between the electric control box 41 and the fan 3 can ensure that during the operation of the fan 3, part of the airflow will flow into the heat dissipation channel to quickly take away the heat conducted by the heat dissipation part 43, thereby improving the heat dissipation efficiency of the circuit board 42.

[0133] By configuring a heat dissipation portion 43 on the electric control box 41, the heat dissipation portion 43 can penetrate the electric control box 41 and be thermally connected to the circuit board 42. The heat dissipation portion 43 partially extends to the outside of the electric control box 41, and then the heat of the circuit board 42 can be conducted to the outside of the electric control box 41 through the heat dissipation portion 43. The airflow generated by the fan 3 in the shell 1 is used to quickly dissipate the heat of the heat dissipation portion 43, thereby improving the heat dissipation efficiency of the electric control box 41 and improving the reliability of the duct machine 1000.

[0134] In some embodiments, the electrical control box 41 is provided with a heat dissipation port 4113, and the heat dissipation portion 43 is inserted into the heat dissipation port 4113, which on the one hand meets the installation requirements of the heat dissipation portion 43, and on the other hand meets the heat dissipation portion 43 to conduct the heat generated by the circuit board 42 to the outside of the electrical control box 41 through the heat dissipation portion 43.

[0135] In some embodiments, since the fan 3 and the electronic control assembly 4 are mounted on the mounting surface 131 of the mounting frame 13, the electronic control assembly 4 is arranged on one side of the fan 3. To improve the heat dissipation efficiency of the heat dissipation portion 43, the heat dissipation portion 43 is arranged close to the fan 3.

[0136] After the fan 3 is started, the air flow after heat exchange through the heat exchanger 21 will flow toward the fan 3. During the flow process, part of the air flow will flow into the inlet of the fan 3, and part of the air flow will flow along the surface of the electrical control box 41 to take away the heat released by the circuit board 42 absorbed by the heat dissipation part 43, thereby improving the heat dissipation efficiency of the heat dissipation part 43.

[0137] 8 and 9 , the housing 1 further comprises a deflector 14. The deflector 14 is disposed at the location of the vent 132, and the cross-sectional area of ​​the deflector 14 increases along the air outlet direction.

[0138] The air guide cover 14 is connected to the vent 132 to guide the airflow output from the fan 3 . The air guide cover 14 guides the airflow toward the air outlet 12 of the housing 1 to increase the air outlet coverage area of ​​the air outlet 12 .

[0139] In some embodiments, a shroud 14 is disposed on one side of the partition 136, forming an air outlet passage between the vent 132 and the air outlet 12. The air outlet passage and cavity 19 are located on either side of the partition 136. The air outlet passage and cavity 19 are disposed at the same end of the housing 1, with the sidewall of the air outlet passage communicating with the cavity 19 via a first ventilation portion. A heat exchanger 21, fan 3, and electronic control assembly 4 are disposed within the housing 1, with the fan 3 communicating with the air outlet 12 via the air outlet passage.

[0140] In some embodiments, referring to Figure 9, the surface of the electric control box 41 close to the volute 31 is a guide surface 410, which is arranged at an angle. The heat dissipation channel is formed between the guide surface 410 and the outer wall of the volute 31. Along the airflow direction of the heat dissipation channel, the heat dissipation channel has a tapered structure.

[0141] To improve the heat dissipation efficiency and operational reliability of the circuit board 42, the surface of the electrical control box 41 near the volute 31 is a guide surface 410. This guide surface 410 directs airflow through the electrical control box 41. A heat dissipation channel is formed between the guide surface 410 and the volute 31. When the fan 3 is activated, the airflow, after heat exchange in the heat exchanger 21, flows toward the fan 3. Part of the airflow is drawn into the fan 3, while the remaining part flows through the heat dissipation channel and is then drawn back into the fan 3. This dissipates heat from the circuit board 42 within the electrical control box 41 through the heat dissipation channel.

[0142] In some embodiments, the heat dissipation portion 43 includes a plurality of heat dissipation fins, which are arranged extending along the rotation axis direction of the fan 3 .

[0143] Because the fins are located within the heat dissipation channel, their extension direction aligns with the airflow within the channel. This allows airflow to flow along the fins, quickly removing heat and improving heat exchange efficiency. Furthermore, the fins guide the airflow, ensuring smooth flow within the channel.

[0144] In some embodiments, the drainage surface 410 formed on the electrical control box 41 may be formed on the box body 411. The drainage surface 410 is formed on the box body 411 and extends obliquely from the inner wall of the housing 1 in a direction away from the water receiving tray 22. Specifically, a first end of the drainage surface 410 of the box body 411 is adjacent to an inner wall of the housing 1 and the water receiving tray 22, while a second end of the drainage surface 410 of the box body 411 is away from the inner wall of the housing 1 and the water receiving tray 22.

[0145] In some embodiments, the box body 411 further includes a first hole 4114 , and a threading portion 46 is provided in the first hole 4114 .

[0146] The cables coupled to the circuit board 42 extend out of the electric control box 41 through the threading portion 46 . The threading portion 46 can seal the portion where the cables are led out to improve the waterproof performance of the electric control assembly 4 .

[0147] 3 , in some embodiments, to improve the installation reliability of the heat exchange assembly 2, the duct air conditioner 1000 further includes a hoisting assembly 5. The fan 3 and the heat exchange assembly 2 are spaced apart in the height direction of the housing. The hoisting assembly 5 is disposed in the housing 1 and located between the fan 3 and the heat exchange assembly 2. The hoisting assembly 5 is configured to suspend and install the heat exchanger 21.

[0148] In some embodiments, the heat exchanger 21 further includes a hanging portion 211 , and the hanging portion 211 is configured to be connected to the hanging assembly 5 when the shell 1 is in an upright state.

[0149] During assembly, the heat exchanger 21 can be installed after the hoisting assembly 5 is installed on the housing 1. After the heat exchanger 21 is inserted into the housing 1 through the water tray 22, the heat exchanger 21 is then hung from the hoisting assembly 5 via the hanging portion 211. This allows the heat exchanger 21 to be suspended and installed via the hoisting assembly 5. This allows the hoisting assembly 5 to bear the weight of the heat exchanger 21, reducing damage to the water tray 22 caused by the impact of the heat exchanger 21 in the event of a fall.

[0150] 6 , the hanging assembly 5 includes a support portion 51 , which is disposed in the housing 1 . The hanging assembly 5 is fixed in the housing 1 via the support portion 51 .

[0151] In some embodiments, the hanging assembly 5 further includes a second bearing portion 52 , which is disposed on the supporting portion 51 so as to support the second bearing portion 52 through the supporting portion 51 .

[0152] In some embodiments, the second bearing portion 52 is arranged alternately with the supporting portion 51. Referring to FIG10 , the hanging portion 211 is hung on the second bearing portion 52.

[0153] 6 and 7 , the second supporting portion 52 includes a supporting portion body 520 and a second limiting portion 521 . The hanging portion 211 is coupled to the second limiting portion 521 to limit the position of the heat exchanger 21 .

[0154] On the one hand, the hanging portion 211 is hung on the second bearing portion 52 to realize the hanging installation of the heat exchanger through the second bearing portion 52; on the other hand, the second limiting portion 521 set on the second bearing portion 52 is used to limit the hanging portion 211, which is beneficial to the installation of the heat exchanger.

[0155] In some embodiments, since the support portion 51 needs to be securely mounted to the housing 1 and provide support for the heat exchanger 21, the hoisting assembly 5 further includes a second reinforcement member 53 (structural reinforcement member). The second reinforcement member 53 is disposed on the support portion 51 and extends along the length of the support portion 51.

[0156] In some embodiments, the support portion 51 and the second bearing portion 52 are formed by bending sheet metal. To enhance the overall structural strength and supporting capacity of the support portion 51, the support portion 51 is additionally provided with a second reinforcement member 53. The second reinforcement member 53 extends along the length of the support portion 51 and is fixed to the support portion 51, thereby enhancing the overall structural strength of the support portion 51.

[0157] In some embodiments, a plug-in portion is provided at the first end of the support portion 51, and a fixing portion is provided at the second end of the support portion 51. A plug-in mating portion is provided in the housing 1, and a fixing mating portion is also provided in the housing 1. The plug-in mating portion and the plug-in mating portion are plugged together, and a screw securely connects the fixing portion and the fixed connection portion.

[0158] In order to facilitate the assembly of the support part 51, a plug-in part is provided at the first end of the support part 51. During installation, the plug-in part is inserted into the plug-in fitting part in the shell 1 to achieve pre-assembly. Then, the fixing part and the fixed connection part are fixed together by screws, thereby fixing the support part 51 to the shell 1.

[0159] In some embodiments, the fixing portion and the fixing connection portion can be in the form of a through hole and a threaded hole. For example, a screw passes through the through hole and is threadedly connected in the threaded hole.

[0160] In some embodiments, when the housing 1 includes a support frame 15 and a plurality of mounting plates 16 , and the mounting plates 16 are disposed on the support frame 15 , the plug-in fitting portion and the fixed fitting portion are disposed on the support frame 15 .

[0161] 6 , the plug portion includes a first tongue 511 provided at the end of the support portion 51, and the first tongue 511 extends along the length of the support portion 51. The plug-fitting portion includes a first socket provided on the support frame 15, and the first tongue 511 is inserted into the first socket.

[0162] Thus, during assembly, the first inserting tongue 511 is inserted into the corresponding first insertion hole of the support frame 15, so that the support portion 51 is positioned by the cooperation between the first inserting tongue 511 and the first insertion hole, thereby pre-assembling the support portion 51. During assembly, the first inserting tongue 511 adopts a plug-in method to improve assembly efficiency.

[0163] In some embodiments, to improve the reliability of the plugging, referring to FIG. 6 , the plugging portion further includes a second plug tongue 512 , which extends along the length direction of the support portion 51 , and is arranged side by side with the first plug tongue 511 .

[0164] The plug-in portion further includes a bent portion 513 . The bent portion 513 is disposed at the free end of the second plug-in tongue 512 and extends away from the first plug-in tongue 511 .

[0165] The plug-in fitting portion further includes a second socket provided on the support frame 15 , the second tongue 512 is inserted into the second socket, the bent portion 513 is inserted into the second socket, and is configured to restrict the second tongue 512 from being disengaged from the second socket.

[0166] In this way, the second tongue 512 of the plug-in portion cooperates with the first tongue 511 and is inserted into the corresponding socket of the support frame 15. After the second tongue 512 is inserted into the second socket, the bent portion 513 of the second tongue 512 can be hooked on the edge of the second socket to prevent the second tongue 512 from being disengaged from the second socket, thereby improving the convenience during the assembly process.

[0167] In some embodiments, referring to FIG10 , the heat exchanger 21 includes two heat exchange sections, namely a first heat exchange section 212 and a second heat exchange section 213. The first heat exchange section 212 and the second heat exchange section 213 are arranged at an angle relative to each other. For example, the first heat exchange section 212 and the second heat exchange section 213 are connected at one end (such as the first end) close to each other, and the second ends of the first heat exchange section 212 and the second heat exchange section 213 extend away from each other. The first heat exchange section 212 and the second heat exchange section 213 can be arranged at a predetermined angle. The first heat exchange section 212 and the second heat exchange section 213 are configured with refrigerant pipes and heat dissipation fins to meet ventilation and heat dissipation requirements.

[0168] In some embodiments, the heat exchanger 21 also includes a sealing portion 214, which is arranged on the corresponding sides of the first heat exchange portion 212 and the second heat exchange portion 213, so as to seal the two sides of the first heat exchange portion 212 and the second heat exchange portion 213 through the sealing portion 214 to prevent airflow from leaking from the two sides of the first heat exchange portion 212 and the second heat exchange portion 213.

[0169] In some embodiments, the heat exchanger 21 further includes a third shielding portion 215 (shielding portion), which is disposed at the first ends of the first heat exchange portion 212 and the second heat exchange portion 213. An air inlet area is formed between the second ends of the first heat exchange portion 212 and the second heat exchange portion 213. The third shielding portion 215 can be fixedly connected to the first heat exchange portion 212 and the second heat exchange portion 213. The third shielding portion 215 can also cover the ends of the first heat exchange portion 212 and the second heat exchange portion 213 to prevent airflow from leaking between the ends of the first heat exchange portion 212 and the second heat exchange portion 213.

[0170] In some embodiments, the hanging portion 211 of the heat exchanger 21 is disposed on the third shielding portion 215. In this way, the hanging portion 211 can be used to meet the requirements for hanging installation of the heat exchanger, and the third shielding portion 215 can be connected to the first heat exchange portion 212 and the second heat exchange portion 213 to ensure that the first heat exchange portion 212 and the second heat exchange portion 213 are firmly connected to the third shielding portion 215 after hanging installation.

[0171] In some embodiments, the hanging assembly 5 includes at least two supporting portions 51 arranged side by side, and the hanging assembly 5 includes at least two second bearing portions 52 arranged side by side.

[0172] Referring to Figure 10 , the outer surface of the third shielding portion 215 includes a first surface 2151 and a second surface 2152, which are arranged at an angle relative to each other. Two hanging portions 211 are provided on the outer surface of the third shielding portion 215: one hanging portion 211 is provided on the first surface 2151, and the other hanging portion 211 is provided on the second surface 2152. The two hanging portions 211 are spaced apart. The hanging portions 211 are provided on the corresponding second supporting portions 52.

[0173] In this way, by providing two hanging parts 211 spaced apart and staggered on the outer surface of the third shielding part 215, the two hanging parts 211 can firmly hang the entire heat exchanger to ensure the posture stability of the heat exchanger 21 during transportation and use, thereby improving the installation reliability of the hung heat exchanger 21.

[0174] The structure of the fan 3 in some embodiments of the present disclosure is introduced below.

[0175] In some embodiments, as shown in FIG11 , the fan 3 includes a volute 31 , and a cavity is formed inside the volute 31 to accommodate relevant components of the fan 3 (such as an impeller, a motor, and other components).

[0176] In some embodiments, referring to FIG. 12 , the fan 3 further includes an impeller 33 , which is rotatably disposed in the cavity of the volute 31 .

[0177] In some embodiments, the fan 3 further includes a motor 32 , which is fixedly disposed in the volute 31 and connected to an impeller 33 . The motor 32 is configured to drive the impeller 33 to rotate in the volute 31 .

[0178] 13 , the motor 32 includes a motor body 320 and a rotating shaft 321 . The motor body 320 is fixedly connected to the rotating shaft 321 to rotate the rotating shaft 321 . The rotating shaft 321 passes through the impeller 33 to drive the impeller 33 to rotate in the volute 31 .

[0179] During use, the ducted air conditioner 1000 can be installed vertically or horizontally. Under different installation conditions, the installation angle and relative position of the fan 3 within the housing 1 will also change. Therefore, to adapt to the different installation conditions of the ducted air conditioner 1000, it is necessary to improve the assembly accuracy and structural stability between the motor 32 and the volute 31 of the fan 3, and between the impeller 33 and the volute 31, to improve the operational reliability of the fan 3. In addition, during the transportation or handling of the ducted air conditioner 1000, vibrations caused by collisions can also affect the operational reliability of the fan 3.

[0180] In some embodiments, referring to FIG. 13 , the fan 3 further includes a mounting assembly 34 . In this case, the motor 32 and the impeller 33 are respectively fixed to the volute 31 via the mounting assembly 34 to improve the structural stability of the fan 3 .

[0181] 12 , the mounting assembly 34 includes a first bracket 341 (load-bearing bracket), which is disposed on one side of the volute 31 and fixedly connected to the volute 31. The first bracket 341 is configured to support the motor body 320.

[0182] In some embodiments, the mounting assembly 34 further includes a second bracket 342 (fixing bracket) connected to the first bracket 341 to further fix the motor body 320 .

[0183] The motor body 320 is disposed between the first bracket 341 and the second bracket 342 . In this way, the first bracket 341 and the second bracket 342 can fix the motor body 320 to the one side of the volute 31 .

[0184] In some embodiments, the mounting assembly 34 further includes a third bracket 343 (auxiliary bracket), which is disposed on a side of the volute 31 opposite the first bracket 341. The third bracket 343 is disposed opposite the first bracket 341. The third bracket 343 is configured to support the free end of the rotating shaft 321. The free end of the rotating shaft 321 is rotatably connected to the third bracket 343.

[0185] During assembly of the fan 3, the first end of the motor body 320 is fixed between the first bracket 341 and the second bracket 342, and the second end of the motor body 320 is connected to the shaft 321. The free end of the shaft 321 passes through the impeller 33 and is connected to the third bracket 343.

[0186] In this way, after the fan 3 is assembled, the motor body 320 located on one side of the impeller 33 is firmly fixed to the first bracket 341, and the free end of the rotating shaft 321 located on the other side of the impeller 33 is supported by the third bracket 343, so that the motor 32 and the impeller 33 can be supported and fixed by the mounting assembly 34 during the transportation and handling of the duct machine 1000, or when the installation state is changed, thereby improving the structural stability of the fan 3.

[0187] In summary, by installing the motor 32 to the volute 31 with the assistance of the installation component 34, the motor 32 can be reliably supported on both sides of the impeller 33 to reduce the occurrence of deviation of the motor 32, thereby reducing the change in the installation position of the impeller 33, avoiding surge or inaccurate air volume in the fan 3, and improving the reliability of the duct machine 1000.

[0188] In some embodiments, referring to FIG. 14 , the first bracket 341 includes a first bracket body 3410 and a first bearing portion 3411 (bearing groove). The first bearing portion 3411 is disposed on the first bracket body 3410 and is configured to bear against the motor body 320. The motor body 320 is located in the first bearing portion 3411. For example, the first bearing portion 3411 is a bearing groove. The second bracket 342 is disposed on one side of the first bracket 341 and is configured to press against the motor 32 to prevent the motor 32 from detaching from the first bearing portion 3411.

[0189] It is understood that the provision of the first supporting portion 3411 facilitates positioning of the motor 32 to achieve pre-assembly of the motor 32. During assembly, the motor body 320 can be placed in the first supporting portion 3411, and then the second bracket 342 can be assembled to the first bracket 341, thereby securing the motor 32 to the first bracket 341 using the second bracket 342.

[0190] 14 , in some embodiments, to achieve a fixed connection between the first bracket 341 and the volute 31, the first bracket 341 further includes a plurality of connecting portions 3412, which are distributed around the first bearing portion 3411. A first end of any one of the plurality of connecting portions 3412 is connected to the first bracket body 3410, and a second end of any one of the connecting portions 3412 extends outward to connect to the volute 31.

[0191] For example, the second end of any one of the connecting portions 3412 is disposed toward the outside of the volute 31 and extends radially along the end surface of the one side of the volute 31 .

[0192] In some embodiments, the connecting portion 3412 is detachably mounted on the volute 31 .

[0193] It should be noted that the connecting portion 3412 can be an integral structure with the first bracket body 3410. This facilitates installation and improves the assembly efficiency of the fan assembly 3.

[0194] Of course, the connecting portion 3412 can also be a separate structure. One end of the connecting portion 3412 is fixedly attached to the first bracket body 3410, and the free end of the connecting portion 3412 is fixedly connected to the volute 31 by a locking member such as a screw. In this way, if the connecting portion 3412 is damaged, it can be easily removed and replaced, reducing maintenance costs.

[0195] In some embodiments, referring to Figures 14 and 15, in order to ensure that the second bracket 342 is securely assembled on the first bracket 341, the first bracket 341 also includes a first clamping portion 3413 (insertion tongue), which is arranged on both sides of the first bracket body 3410 and located at the first end of the first supporting portion 3411.

[0196] The second bracket 342 includes a second bracket body 3420 and a first mating portion 3421 (jack) disposed at a first end of the second bracket body 3420. The first clamping portion 3413 is inserted into the first mating portion 3421 to connect the first end of the second bracket 342 to the first end of the first bracket 341.

[0197] It is understandable that the cooperation between the first clamping portion 3413 and the first matching portion 3421 can reduce the amount of screws used, thereby improving assembly efficiency.

[0198] In some embodiments, the first bracket 341 further includes a second hole 3414 (screw hole) disposed at the second end of the first bracket body 3410. The second bracket 342 further includes a third hole 3422 (connection through hole) disposed at the second end of the second bracket body 3420.

[0199] It will be appreciated that the screw may pass through the third hole 3422 and be threadedly connected in the second hole 3414 .

[0200] In the process of fixing the motor body 320 to the first bracket 341 through the second bracket 342, the first end of the second bracket 342 is first quickly plugged into the first clamping portion 3413 through the first matching portion 3421, and then the second end of the second bracket 342 is pressed against one side of the motor 32, and the screw is passed through the third hole 3422 and threaded into the second hole 3414 to complete the assembly of the second bracket 342 and the first bracket 341.

[0201] In some embodiments, a first clamping portion 3413 and a second hole 3414 are respectively disposed on both sides of the first supporting portion 3411 , and a second bracket 342 is respectively disposed on both sides of the first supporting portion 3411 .

[0202] In some embodiments, the first bracket 341 can be made of sheet metal, which is beneficial to ensuring the structural strength of the first bracket 341 and improving production efficiency.

[0203] In some embodiments, first supporting portions 3411 may be formed on both sides of the first bracket body 341. In this case, second brackets 342 are connected to both sides of the first bracket 341. This improves the installation reliability of the motor body 320 and the volute 31.

[0204] In some embodiments, to improve the overall structural strength of the first bracket 341, referring to FIG. 13 , the mounting assembly 34 further includes a first reinforcement member 344 (reinforcement member). The first reinforcement member 344 can be connected to both sides of the first bracket 341, such as between the two first bearing portions 3411. The first reinforcement member 344 extends along the length direction (e.g., axial direction) of the motor body 320 and spans the motor body 320 to connect the two sides of the first bracket 341, thereby improving the structural strength of the first bracket 341.

[0205] 16 , the motor 32 further includes a first shock absorbing portion 322 , which is disposed at both ends of the motor body 320 . The first shock absorbing portion 322 is clamped by a first bracket 341 and a second bracket 342 at one side away from the motor body 320 .

[0206] For example, a portion of the first shock absorbing portion 322 is located in the first bearing portion 3411, and another portion of the first shock absorbing portion 322 is located in the second bracket 342. Thus, by providing the first shock absorbing portions 322 at both ends of the motor body 320, the first shock absorbing portions 322 can be used to absorb vibrations generated during the operation of the motor 32, thereby reducing the noise generated during the operation of the motor 32.

[0207] In some embodiments, the first shock absorbing portion 322 may be a flexible member such as a shock absorbing sleeve or a shock absorbing block.

[0208] In some embodiments, the mounting assembly 34 further includes a snap ring 323, which is sleeved onto the exterior of the first shock absorbing portion 322. During use, the snap ring 323 is clamped between the first bracket 341 and the second bracket 342 to secure the first shock absorbing portion 322 to the end of the motor body 320, thereby improving the reliability of the first shock absorbing portion 322.

[0209] In some embodiments, referring to FIG. 16 , the snap ring 323 includes a snap ring body 3230 and a third notch 3231. The third notch 3231 is configured to provide a compression gap between the two ends of the third notch 3231 of the snap ring 323 after the snap ring 323 is clamped between the first bracket 341 and the second bracket 342, thereby reducing the distance between the two ends of the snap ring 323. This improves the secure installation of the motor body 320 between the first bracket 341 and the second bracket 342.

[0210] For example, the snap ring 323 is made of a hard material such as metal.

[0211] After the first shock absorber 322 is assembled to the motor 32, a snap ring 323 is mounted on the outside of the first shock absorber 322 to protect the first shock absorber 322. The third notch 3231 of the snap ring 323 allows the snap ring 323 to reduce in size (e.g., circumference) when the second bracket 342 compresses the snap ring 323, thereby securely fixing the first shock absorber 322 to the motor 32.

[0212] In some embodiments, the retaining ring 323 further includes a third limiting portion 3232 disposed on the outer circumference of the retaining ring body 3230. The provision of the third limiting portion 3232 can limit the motor body 320. Thus, after the motor body 320 is installed in the first bearing portion 3411, the third limiting portion 3232 enables the retaining ring 323 to cooperate with the first bracket 341, so that the portion of the first bracket body 3410 formed with the first bearing portion 3411 is retained in the third limiting portion 3232, thereby improving the installation security of the motor body 320.

[0213] 13 and 15 , the second bracket 342 further includes a fourth stopper 3423 (blocking portion) disposed on one side of the second bracket body 3420. The fourth stopper 3423 is configured to block the outside of the first shock absorbing portion 322 to prevent the first shock absorbing portion 322 from being dislodged from the end of the motor 32.

[0214] 13 , after the second bracket 342 is assembled to the first bracket 341, the fourth stopper 3423 is located outside the first shock absorbing portion 322 and extends toward the first bracket 341. At this time, the first shock absorbing portion 322 is located between the fourth stopper 3423 and the end surface of the motor body 320.

[0215] It is understood that during use, the rotating shaft 321 of the motor 32, while driving the impeller 33, causes the motor body 320 to vibrate. If this vibration is transmitted to the first shock absorber 322, it may cause the first shock absorber 322 to deform or shift. The fourth limiting portion 3423 provided on the second bracket 342 shields and limits the outer side of the first shock absorber 322, ensuring that the first shock absorber 322 remains securely attached to the end of the motor 32 during use, thereby improving the reliability of the motor.

[0216] In some embodiments, to limit the rotation of the motor 32 relative to the first shock absorber 322, the first shock absorber 322 further includes a first shock absorber body. The first shock absorber 322 also includes a positioning portion disposed on the first shock absorber body. The positioning portion is disposed on the inner circumference of the first shock absorber body (a side surface close to the central axis of the motor body 320). The motor 32 also includes a positioning mating portion disposed on the circumference of the side of the motor body 320 connected to the first shock absorber 322. The positioning portion is connected to the positioning mating portion to limit the rotation of the motor 32 relative to the first shock absorber 322.

[0217] For example, the positioning portion may be a recessed structure or a raised structure, and correspondingly, the positioning matching portion may be a raised structure or a recessed structure.

[0218] In other embodiments, referring to Figure 17, in order to ensure that the rotating shaft 321 can rotate smoothly relative to the third bracket 343, the mounting assembly 34 also includes a bearing 345, the bearing 345 is arranged on the third bracket 343, and the free end of the rotating shaft 321 is arranged in the bearing 345 to realize the rotational connection between the motor and the third bracket 343 through the bearing 345.

[0219] Referring to Figure 17 , the third bracket 343 includes a third bracket body 3430. The third bracket 343 also includes a fourth hole 3433 (mounting hole) disposed in the third bracket body 3430. The fourth hole 3433 is disposed on a side of the third bracket body 3430 that is adjacent to the rotating shaft 321. A bearing 345 is disposed in the fourth hole 3433, and the free end of the rotating shaft 321 of the motor 32 is inserted into the bearing 345.

[0220] In this way, by providing the bearing 345 on the third bracket 343 , not only can the rotating shaft 321 be supported by the third bracket 343 , but the rotating shaft 321 can also rotate smoothly.

[0221] 17 , the third bracket 343 further includes a third shock absorbing portion 3431, which is disposed at the location of the fourth hole 3433. Thus, the bearing 345 can be mounted in the fourth hole 3433 of the third bracket 343 via the third shock absorbing portion 3431, and the third shock absorbing portion 3431 can provide support and shock absorption for the bearing 345.

[0222] The third shock absorbing portion 3431 includes a mounting groove in which the bearing 345 is disposed and a vent hole communicating with the mounting groove.

[0223] It is understandable that when the shaft 321 of the motor 32 rotates at high speed, the gas in the mounting groove will experience pressure fluctuations, which will produce abnormal sounds. By providing vent holes, the air pressure in the mounting groove can be balanced, thereby reducing the occurrence of abnormal sounds.

[0224] In some embodiments, referring to FIG. 17 , the third shock absorber 3431 further includes a third shock absorber body 34310. The third shock absorber 3431 further includes a third positioning portion 34311 disposed on the third shock absorber body 34310. A mounting groove and a vent hole are respectively disposed on the third shock absorber body 34310. The third positioning portion 34311 is disposed on the outer circumference of the third shock absorber body 34310. The third positioning portion 34311 abuts against the outer surface of the third bracket body 3430. In some embodiments, the third bracket 343 further includes an end cap 3432 disposed on one side of the third bracket 343 and covering the third positioning portion 34311. This facilitates securing the third shock absorber 3431 to the third bracket 343 via the end cap 3432.

[0225] In some embodiments, the end cover 3432 includes an escape opening, and the third shock absorbing portion body 34310 passes through the escape opening so that the vent hole is connected to the outside of the end cover 3432.

[0226] In some embodiments, a mounting assembly 34 is disposed on the volute 31, and a motor 32 is disposed on the mounting assembly 34. A rotating shaft 321 of the motor 32 passes through the impeller 33. The mounting assembly 34 is configured to support and fix the motor 32 on one side of the impeller 33, and is also configured to support the free end of the rotating shaft 321 on the other side of the impeller 33.

[0227] An embodiment of a wind turbine is described above, but the present disclosure is not limited thereto. Another embodiment of a wind turbine is described below.

[0228] In some embodiments, referring to FIG. 18 , the fan 3 includes a volute 31 .

[0229] In some embodiments, the fan 3 further includes an impeller 33 , which is rotatably disposed in the volute 31 .

[0230] In some embodiments, the fan 3 further includes a motor 32 , which is coupled to the impeller 33 . The motor 32 is configured to drive the impeller 33 to rotate in the volute 31 .

[0231] The motor 32 includes a motor body 320 and a rotating shaft 321 . The rotating shaft 321 passes through the impeller 33 .

[0232] The difference between the fan 3 described in Figures 11 to 17 and the fan 3 described in Figures 18 to 23 is that the motor 32 further includes a plurality of third mounting portions 324. Referring to Figure 22, the plurality of third mounting portions 324 are provided on the outer circumference of the motor body 320 and are spaced apart along a direction surrounding the central axis of the motor body 320.

[0233] 19 , the fan 3 further includes a mounting assembly 34 , through which the motor 32 is fixed to the housing 1 .

[0234] In some embodiments, the mounting assembly 34 includes a plurality of fourth brackets 346 (mounting brackets). The fourth brackets 346 are mounted on at least one of the plurality of third mounting portions 324 and connected to one side (e.g., the outer peripheral side) of the volute 31. The plurality of fourth brackets 346 are spaced apart and arranged outside the motor body 320 and connected to the volute 31 to meet the support and installation requirements of the motor body 320.

[0235] In some embodiments, the mounting assembly 34 further includes a third bracket 343 , which is disposed on the other side of the volute 31 (eg, one axial side), and the free end of the rotating shaft 321 of the motor 32 is rotatably disposed on the third bracket 343 .

[0236] The rotating shaft 321 is connected to the third bracket 343 after passing through the impeller 33. In this way, the third bracket 343 can support the free end of the rotating shaft 321.

[0237] In this way, the motor 32 is installed to the volute 31 with the assistance of the mounting assembly 34, the motor body 320 is fixed to the volute 31 through the fourth bracket 346, and the free end of the rotating shaft 321 is supported by the third bracket 343, so that during the transportation of the duct machine 1000, the motor 32 can be reliably supported and fixed by the mounting assembly 34.

[0238] It is understood that the provision of multiple fourth brackets 346 facilitates the operator to adjust the direction and angle of the motor 32 during assembly, thereby improving the installation stability between the motor 32, the impeller 33, and the volute 31. The provision of multiple fourth brackets 346 can also support and secure the motor body 320 at multiple angles, thereby improving the reliability of the installation of the motor 32.

[0239] Since the motor 32 can be supported on both sides of the impeller 33 , the impeller 33 can also be reliably supported and installed on the rotating shaft 321 after the fan 3 is assembled.

[0240] During transportation, since the mounting assembly 34 reliably supports the motor 32 on both sides of the impeller 33, it can reduce the occurrence of the motor 32 being deflected and causing the installation position of the impeller 33 to change, which is beneficial to improving the reliability of the duct machine 1000.

[0241] 20 , in some embodiments, the fourth bracket 346 includes a first arm 3461 (fixed arm) connected to the third mounting portion 324 of the motor body 320 and extending along the axial direction of the motor body 320 .

[0242] In some embodiments, the fourth bracket 346 further includes a second arm 3462 (support arm), a first end of the second arm 3462 being connected to the end (first end) of the first arm 3461 on the side close to the housing 1, and a second end of the second arm 3462 being connected to the volute 31. In this way, the fourth bracket 346 can be fixedly connected to the volute 31 via the second arm 3462, thereby fixing the motor body 320 to the volute 31.

[0243] In some embodiments, the fourth bracket 346 further includes a second mating portion 3463 (mounting mating portion), which is disposed on a side of the first arm 3461 adjacent to the third mounting portion 324 and extends along the length of the first arm 3461. The first arm 3461 is connected to the third mounting portion 324 via the second mating portion 3463.

[0244] During the installation process, the second matching portion 3463 of the first arm 3461 is set on the corresponding third installation portion 324, and the second arm 3462 is connected to the volute 31 to achieve a fixed connection between the motor body 320 and the housing 1.

[0245] In some embodiments, the first arm 3461 and the second arm 3462 form a predetermined angle. When the angle between the first arm 3461 and the second arm 3462 is 90 degrees, the fourth bracket 346 is formed into an L-shaped structure. In this way, the first arm 3461 of the fourth bracket 346 is connected to the motor 32, and the second arm 3462 is fixedly connected to the housing 1, so that the motor body 320 can be installed in the volute 31.

[0246] It should be noted that the third mounting portion 324 and the second mating portion 3463 can have various structural forms. For example, the third mounting portion 324 can be a first latching groove formed on the outer circumference of the motor 32, and the second mating portion 3463 can be a first engaging protrusion formed on the first arm 3461. The first engaging protrusion is engaged with the first latching groove to achieve the installation of the fourth bracket 346 and the motor 32.

[0247] Alternatively, the third mounting portion 324 is a second snap-fitting protrusion formed on the outer circumference of the motor 32, and the second matching portion 3463 is a second snap-fitting groove formed on the first arm 3461, and the second snap-fitting protrusion is snapped into the second snap-fitting groove to achieve the installation of the fourth bracket 346 and the motor 32.

[0248] In some embodiments, referring to FIG. 20 , to position the motor 32 during installation, the fourth bracket 346 further includes a first stopper 3464 (a stopper protrusion). The first stopper 3464 is disposed at the end (the second end) of the first arm 3461 that is away from the second arm 3462. The first stopper 3464 can abut against the end surface of the motor body 320 that is away from the second arm 3462.

[0249] During assembly, the second mating portion 3463 is first engaged with the third mounting portion 324 to mount the first arm 3461 on the motor 32. The position of the motor 32 is then adjusted so that the first stopper 3464 abuts against the end face of the motor 32 facing away from the housing 1. This allows the motor 32 to be positioned after being inserted into the end face of the volute 31 using the first stopper 3464 of the first arm 3461, improving the ease and accuracy of motor 32 assembly.

[0250] 19 , 20 , and 23 , the second arm 3462 includes a second arm body 34620. The second arm 3462 also includes a fifth hole 34621 (assembly hole) disposed in the second arm body 34620. The fifth hole 34621 is disposed at a second end of the second arm body 34620 away from the first arm 3461. The fourth bracket 346 is assembled to the housing 1 through the fifth hole 34621.

[0251] For example, the second arm 3462 is connected to the housing 1 via a connecting bolt and a connecting nut. The connecting bolt passes through the fifth hole 34621 and is fixed to the volute 31 via the connecting nut.

[0252] In some embodiments, the mounting assembly 34 further includes a shock absorbing assembly, which is disposed at the connection between the fifth hole 34621 and the housing 1 to reduce vibration generated when the motor 32 is running.

[0253] In some embodiments, referring to FIG. 19 , the shock absorbing assembly includes a second shock absorbing portion 347 (shock absorbing sleeve), and the second shock absorbing portion 347 is connected to the second arm 3462 through a fifth hole 34621 .

[0254] The second shock absorbing portion 347 includes a second shock absorbing portion body 3470 and a second clamping portion 3471. The second clamping portion 3471 is disposed on a side of the second shock absorbing portion body 3470 near the fifth hole 34621 and is inserted into the fifth hole 34621. Thus, after the second clamping portion 3471 is inserted into the fifth hole 34621, the second shock absorbing portion body 3470 can abut against the volute 31 to provide a shock absorbing effect.

[0255] 23 , the second shock absorbing portion 347 further includes a sixth hole 3472 (stepped hole). The sixth hole 3472 extends axially through at least a portion of the second shock absorbing portion body 3470. The sixth hole 3472 includes a first sub-hole 34721 and a second sub-hole 34722 that are interconnected. The diameter of the first sub-hole 34721 is smaller than that of the second sub-hole 34722, and at least a portion of the first sub-hole 34721 extends through the second engaging portion 3471.

[0256] In some embodiments, the shock-absorbing assembly further includes a third mating portion 348 (metal sleeve), which is disposed in the first sub-hole 34721. A connecting bolt passes through the third mating portion 348 and is secured to the volute 31 via a connecting nut. This allows for position limiting while ensuring shock absorption, preventing the impeller 33 of the fan 3 from being misaligned, and improving assembly accuracy.

[0257] By disposing the second shock-absorbing portion 347 in the fifth hole 34621 of the second arm 3462 and the third mating portion 348 in the sixth hole 3472 formed by the second shock-absorbing portion 347, when the fourth bracket 346 is assembled with the volute 31, the connecting bolt passes through the third mating portion 348 and is connected to the volute 31. This third mating portion 348 protects the second shock-absorbing portion 347, preventing the connecting bolt from damaging it. Furthermore, the second arm 3462 is connected to the connecting bolt via the second shock-absorbing portion 347, which provides a good shock-absorbing effect, thereby reducing the operating noise of the motor 32.

[0258] It is understood that the end surface of the second shock absorbing portion 347 adjacent to the second sub-hole 34722 abuts against the volute 31, and the second sub-hole segment 34722 is spaced apart from the connecting bolt to form a buffer zone between the second sub-hole segment 34722 and the volute 31. The buffer zone is configured to generate a certain amount of compression when the connecting bolt is installed in the second shock absorbing portion 347 and squeezes the second shock absorbing portion 347, thereby firmly mounting the connecting bolt to the housing 1.

[0259] In some embodiments, the second shock absorbing parts 347 are provided corresponding to the fourth brackets 346. For example, the number of the second shock absorbing parts 347 can be equal to the number of the fourth brackets 346. To limit the amount of compression of the second shock absorbing parts 347, a third mating portion 348 is provided inside the second shock absorbing parts 347 to limit the amount of compression of the second shock absorbing parts 347. This prevents eccentricity of the rotating shaft 321 of the motor 32 due to different amounts of compression when multiple second shock absorbing parts 347 are installed, thereby improving the assembly accuracy and reliability of the fan 3.

[0260] 19 and 21 , the mounting assembly 34 further includes a locking member 349 disposed around the outer periphery of the motor 32. The locking member 349 is located around the outer periphery of the plurality of fourth brackets 346 and is configured to lock the plurality of fourth brackets 346 to the motor 32.

[0261] It is understandable that by fastening each fourth bracket 346 to the motor 32 through the locking member 349 outside the motor 32, it is beneficial to improve the connection reliability between the fourth bracket 346 and the motor 32.

[0262] In some embodiments, both ends of the locking member 349 are open. After the locking member 349 is installed on the fourth bracket 346 , the locking member 349 will stop at the first arm 3461 so that the first arm 3461 is pressed against the motor 32 .

[0263] In some embodiments, to limit the position of the locking member 349, referring to FIG. 20 , the fourth bracket 346 further includes a first positioning portion 3465, which is disposed on a side of the first arm 3461 away from the motor body 320. The locking member 349 can be disposed in the first positioning portion 3465, which is configured to limit the locking member 349 from moving axially along the motor body 320.

[0264] In some embodiments, the locking member 349 surrounds the outer periphery of the motor 32 and is locked in place in the first positioning portion 3465 of the corresponding fourth bracket 346. This improves the installation accuracy of the locking member 349 and limits the movement of the locking member 349 along the axial direction of the motor 32.

[0265] 21 , the locking member 349 includes a locking member body 3490 and a plurality of pairs of second positioning portions 3491. The second positioning portions 3491 are disposed on a side surface (e.g., an inner surface) of the locking member body 3490 near the fourth bracket 346. The second positioning portions 3491 are configured to limit the rotation of the locking member body 3490 along the circumferential direction of the motor 32.

[0266] For example, a positioning area is formed between two adjacent second positioning portions 3491 , and the fourth bracket 346 is located in the corresponding positioning area.

[0267] In this way, by setting multiple pairs of second positioning portions 3491 on the inner surface of the locking member 349 and arranging two adjacent second positioning portions 3491 on both sides of the first arm 3461, the position of the locking member 349 can be further limited and the assembly efficiency of the locking member 349 can be improved.

[0268] In summary, the setting of the first positioning portion 3465 and the second positioning portion 3491 can limit the motor in the axial and circumferential directions respectively, so that a cross limit is formed between the fourth bracket 346 and the locking member 349, which facilitates the installation and fixation of the locking member 349.

One of the two extensions 3492 is provided with a through-hole, and the other extension 3492 is provided with a fastening nut. A fastening bolt passes through the through-hole and is threadedly engaged with the fastening nut.

[0270] In this way, the extension parts 3492 at both ends of the locking member 349 are tightened by tightening the bolts, so that the extension parts 3492 at both ends of the locking member 349 abut against each other, thereby achieving the locking of the locking member 349.

[0271] 21 , the locking member 349 further includes a plurality of seventh holes 3493 (stress relief holes), which are sequentially arranged along the circumference of the locking member body 3490. For example, the seventh holes 3493 may extend along the axis of the locking member.

[0272] It is understandable that, since the locking member 349 has an arc-shaped structure, by designing the seventh hole 3493 on both sides of the locking member 349, the arc-shaped structure of the locking member 349 can be prevented from rebounding.

[0273] In some embodiments, the locking member 349 also includes a plurality of reinforcing ribs 3494, which are arranged in sequence along the circumferential direction of the locking member body 3490, and at least one of the plurality of reinforcing ribs 3494 extends along an axial direction parallel to the locking member body 3490. In this way, the strength of the locking member 349 can be improved.

[0274] In some embodiments, a reinforcing rib 3494 may also be formed between the extension portion 3492 and the locking member body 3490 to further enhance the structural strength of the extension portion 3492 and prevent the extension portion 3492 from being deformed.

[0275] 19 , the mounting assembly 34 further includes a bearing 345 , which is disposed in the third bracket 343 . The free end of the rotating shaft 321 of the motor 32 is inserted into the bearing 345 .

[0276] It should be noted that the manner in which the third bracket 343 is configured with a bearing 345 to mount the rotating shaft 321 of the motor 32 is similar to that in the above embodiment and will not be described in detail herein.

[0277] In some embodiments, when the motor 32 is assembled using the mounting assembly 34, the impeller 33 can be arranged between the fourth bracket 346 and the third bracket 343 of the mounting assembly 34, and the fourth bracket 346 and the third bracket 343 are respectively provided on the volute 31. The fourth bracket 346 is configured to support and fix the motor body 320 on one side of the impeller 33, and the third bracket 343 is configured to support the free end of the rotating shaft 321 of the motor 32 on the other side of the impeller 33.

[0278] In this way, the fourth bracket 346 and the third bracket 343 are distributed on both sides of the impeller 33 to support the motor body 320 and the free end of the rotating shaft 321, thereby achieving the installation of the motor 32.
