[0037] Some embodiments of the present disclosure provide an air conditioner.

[0038] As shown in FIG. 1A and FIG. 1B , the air conditioner 2000 includes an outdoor unit 20 .

[0039] In some embodiments, the air conditioner 2000 further includes an indoor unit 10. The indoor unit 10 is connected to the outdoor unit 20.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] Typically, a ducted air conditioner includes a housing, a heat exchanger, a fan, and an electrical control box. The electrical control box is configured to control the operation of the fan. During use, the ducted air conditioner can be installed vertically or horizontally. In the case of a vertical installation, the fan and electrical control box are usually installed below the heat exchanger. During the operation of the ducted air conditioner, condensed water generated on the surface of the heat exchanger will drip into the water collection tray located below the heat exchanger. If the water collection tray does not drain smoothly, the water in the water collection tray can easily overflow into the electrical control box below, causing a short circuit in the circuit board inside the electrical control box, resulting in damage to the ducted air conditioner.

[0053] To address the aforementioned issues, some embodiments of the present disclosure provide a ducted air conditioner 1000. A drainage surface is provided on the side of the electrical control box facing the water tray to drain water overflowing from the water tray out of the housing 1. Furthermore, the electrical control box is equipped with a sealing plate, a water retaining portion, and a rubber plug for threading wires to prevent water from entering the box, thereby improving the waterproof performance of the box and the reliability of the ducted air conditioner.

[0054] 1C and 2 , the ducted air conditioner 1000 includes a housing 1. The housing 1 includes a first cavity configured to house components such as a heat exchange assembly, a fan, and an electronic control assembly. The housing 1 protects the components within the first cavity.

[0055] In some embodiments, the housing 1 further includes an air inlet 11. In FIG. 1C , the air inlet 11 may be located at the top of the housing 1. Air flow may enter the housing 1 through the air inlet 11 for heat exchange.

[0056] In some embodiments, the housing 1 further includes an air outlet 12 . In FIG. 1C , the air outlet 12 may be located at the bottom of the housing 1 , and the airflow after heat exchange may flow out through the air outlet 12 .

[0057] 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.

[0058] 2 , 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.

[0059] 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.

[0060] 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.

[0061] 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 generated on 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.

[0062] In some embodiments, to ensure that the water in the water tray body 220 can be drained smoothly, 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 .

[0063] In some embodiments, referring to Figures 2 and 3 , 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 air enters the housing 1 through the air inlet 11 to exchange heat with the heat exchanger 21, and then delivers the heat-exchanged air through the air outlet 12.

[0064] In some embodiments, referring to FIG3 , 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 .

[0065] 4 and 5 , in some embodiments, 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 for mounting a circuit board 42 .

[0066] 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.

[0067] It should be noted that the number of circuit boards 42 can be configured according to the functions of the duct machine 1000 .

[0068] In some embodiments, the heat exchange assembly 2 and the electric control box 41 are arranged in sequence along the airflow direction inside the housing 1 .

[0069] For example, referring to Figure 2 , when the housing 1 is in an upright position, the heat exchange assembly 2 is located above the electrical control box 41. At this point, the electrical control box 41 is located below the water tray body 220. During use, water flowing down the surface of the heat exchanger 21 will flow into the water tray body 220 and be discharged through the drain port 222 of the water tray 22 and the drain pipe.

[0070] However, if the water pan 22 does not drain smoothly, the water level in the water pan body 220 will continue to rise and eventually overflow the water pan body 220. At this time, the overflowing water in the water pan body 220 may flow to the electric control box 41 below the water pan body 220, thereby affecting the reliability of the electric control box 41.

[0071] 3 , the electric control box 41 includes an electric control box body and a drainage surface 410. The drainage surface 410 is configured to drain water overflowing from the water receiving tray 22 when the housing 1 is in an upright state.

[0072] For example, the drainage surface 410 is provided on a side of the electric control box body facing the water receiving tray 22. The drainage surface 410 is provided in an inclined manner in the housing 1 to facilitate water drainage.

[0073] In some embodiments of the present disclosure, the electrical control box 41 is provided with a drainage surface 410 facing the water receiving tray 22, and the drainage surface 410 is arranged at an angle. In this way, when the housing 1 is in an upright position, the ducted air conditioner 1000 can drain water overflowing from the water receiving tray 22 through the drainage surface 410.

[0074] Under the guidance of the drainage surface 410, water overflowing from the water receiving pan 22 can flow downward quickly and smoothly through the inclined drainage surface 410. This reduces the impact of water entering the electrical control box 41 on the circuit board 42, thereby improving the waterproof performance of the electrical control box 41 and the reliability of the air duct air conditioner 1000.

[0075] In some embodiments, referring to Figures 4 and 5 , the electric control box body includes a box body 411 disposed within the housing 1. The box body 411 defines a second cavity for mounting a circuit board 42. The circuit board 42 is disposed within the box body 411 and assembled into the housing 1 through the box body 411, thereby achieving a fixed installation between the electric control box and the housing 1.

[0076] In some embodiments, the electric control box body further includes a cover 412, which is connected to the box body 411 to enclose at least a portion of the second cavity. For example, an opening is formed on one side of the box body 411 close to the cover, and the cover 412 is disposed at the opening of the box body 411.

[0077] In some embodiments, the cover 412 is detachably connected to the box body 411. In this way, the cover 412 can be removed from the box body 411 to expose the circuit board 42, thereby facilitating maintenance of the circuit board 42.

[0078] In some embodiments, the drainage surface 410 of the electric control box 41 satisfies at least one of the following conditions: the drainage surface 410 is disposed on the box body 411 , or the drainage surface 410 is disposed on the cover 412 .

[0079] In some embodiments, when the drainage surface 410 is provided on the box body 411, the drainage surface 410 is provided on the inclined outer surface of the box body 411. When the housing 1 is in an upright state, the drainage surface 410 is located on a side of the water receiving pan 22 away from the heat exchanger 21 and is spaced apart from the water receiving pan 22.

[0080] 2, 3, and 7A, the outer surface of the housing 411 facing the water tray 22 and the fan 3 is inclined to form a drainage surface 410. Drainage surface 410 extends obliquely away from the water tray 22, away from an inner wall of the housing 1. For example, a first end of drainage surface 410 is adjacent to an inner wall of the housing 1 and the water tray 22, while a second end of drainage surface 410 is away from the inner wall of the housing 1 and the water tray 22.

[0081] In this way, by arranging the outer surface of the box body 411 to be inclined to form the drainage surface 410 , the inclined outer surface of the box body 411 can be used to drain the water overflowing from the water receiving tray 22 .

[0082] In some embodiments, referring to FIG. 7A , the box body 411 includes a first plate 4111 (mounting plate), a drainage surface 410 is disposed on an outer surface of the first plate 4111 , and a circuit board 42 is disposed on an inner surface of the first plate 4111 .

[0083] In some embodiments, the box body 411 further includes two second plates 4112 (bent plates). The two second plates 4112 are disposed on either side of the first plate 4111, with each second plate 4112 extending away from the water receiving tray 22. For example, the plane on which the first plate 4111 lies can be parallel to the cross-section of the fan 3. Here, the cross-section refers to a plane perpendicular to the rotation axis of the fan 3.

[0084] It is understandable that at least one of the first plate 4111 or the second plate 4112 is disposed on the housing 1 so as to install the box body 411 in the housing 1 .

[0085] By respectively arranging the second plates 4112 on both sides of the first plate 4111 , after the circuit board 42 is fixed to the first plate 4111 , the circuit board 42 can be protected by the second plates 4112 on both sides.

[0086] In some embodiments, the cover 412 can be connected between the two second plates 4112. The cover 412 cooperates with the two second plates 4112 to form a relatively closed second cavity between the box body 411, the cover 412 and the housing 1 to install the circuit board 42.

[0087] 3 and 7B , the electrical control box 41 further includes a maintenance cover 414, which is disposed on one side (e.g., the lower side) of the box body 411 where the heat exchange assembly 2 originally resides. The maintenance cover 414 is detachably connected to the box body 411, allowing for easy removal of the maintenance cover 414 to access the circuit board 42 within the electrical control box 41.

[0088] It is understandable that the maintenance cover 414 , the box body 411 and the cover body 412 cooperate to further improve the sealing performance of the electric control box 41 .

[0089] 7B , the maintenance cover 414 includes a first sub-cover 4141 including a maintenance port and a second sub-cover 4142 detachably disposed on the maintenance port.

[0090] In this way, the maintenance cover 414 is set as a split structure, and 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 to perform maintenance, which can further facilitate later maintenance.

[0091] Furthermore, it should be noted that the second sub-cover 4142 can be arranged to protrude from the outer surface of the first sub-cover 4141. That is, when the ducted air conditioner 1000 is installed vertically, the second sub-cover 4142 extends downward along the outer surface of the first sub-cover 4141. In this way, if water overflows from the water tray 22, the second sub-cover 4142 can guide water flowing onto the surface of the electrical control box 41 downward, facilitating rapid drainage of the water outside the housing 1 and further enhancing the waterproof performance of the electrical control assembly 4.

[0092] In other embodiments, when the drainage surface 410 is disposed on the cover 412 , the drainage surface 410 is disposed on an end of the cover 412 close to the water receiving tray 22 .

[0093] Referring to Figures 3 and 5 , the electrical control box 41 further includes a first shielding portion 413 (first shielding plate). The first shielding portion 413 is disposed on a side of the cover body near the water receiving tray and is arranged obliquely within the housing 1. For example, a first end of the first shielding portion 413 is disposed at an end (i.e., the upper end) of the cover body 412 near the water receiving tray 22, while a second end of the first shielding portion 413 extends obliquely away from the corresponding inner wall of the housing 1 and toward the water receiving tray 22. The surface of the first shielding portion 413 facing the water receiving tray 22 constitutes a drainage surface 410.

[0094] When the housing 1 is in an upright position, the first shielding portion 413 is located between the box body 411 and the water receiving tray 22. For example, the first shielding portion 413 is located at the bottom of the drain outlet 222 of the water receiving tray 22 and covers one side edge (such as the upper edge) of the box body 411 close to the water receiving tray 22.

[0095] In this way, water overflowing from the water receiving tray 22 can fall into the first shielding portion 413 and flow toward the inner wall of the shell 1 under the guidance of the first shielding portion 413 to achieve rapid drainage, thereby preventing water from flowing into the box body 411, which is beneficial to improving the waterproof performance of the electronic control box.

[0096] It should be noted that, in some embodiments, the cover body 412 stops at an inner wall of the shell 1 (such as the rear wall). In this case, the cover body contacts the corresponding inner wall of the shell, and there is no gap between the two. After the water overflowing from the water receiving tray 22 falls onto the first shielding portion 413, it can be discharged through the gap between the two ends of the first shielding portion 413 (the left and right ends as shown in Figure 3) and the corresponding inner wall of the shell.

[0097] Of course, in other embodiments, a preset distance is provided between the cover 412 and the inner wall of the housing 1. At this time, after the water overflowing from the water receiving tray 22 falls on the first shielding portion 413, it can be discharged through the gap between the cover 412 and the inner wall of the housing 1.

[0098] In some other embodiments, referring to Figure 3, the box body 411 and the cover body 412 are respectively provided with drainage surfaces 410. This effectively improves the water discharge efficiency and is more conducive to improving the waterproof effect of the electric control box.

[0099] It is understandable that since the circuit board 42 generates heat when it is powered on and used, it is necessary to perform heat dissipation treatment on the circuit board 42 .

[0100] 7A , the box body 411 further includes a heat dissipation vent 4113 , which is disposed on the first plate 4111 . For example, the heat dissipation vent 4113 may be located on the drainage surface 410 .

[0101] Referring to Figure 6 , the electronic control assembly 4 also includes a heat sink 43. This heat sink 43 is disposed within the electronic control box 41 and is located at the heat dissipation opening 4113. The heat sink 43 plugs into the heat dissipation opening 4113 to seal the heat dissipation opening 4113. The heat sink 43 is thermally conductively connected to the circuit board 42 to dissipate heat from the circuit board 42. The heat sink 43 can be made of a thermally conductive material (such as aluminum or copper).

[0102] In summary, by setting a heat dissipation port 4113 on the first plate body 4111 and setting a heat dissipation portion 43 thermally connected to the circuit board 42 at the heat dissipation port 4113, the heat dissipation portion 43 can be used to dissipate heat from the circuit board 42, which is beneficial to ensuring the reliability of the circuit board.

[0103] In some embodiments, the heat dissipation portion 43 is sealed to the heat dissipation opening 4113 to prevent water overflowing from the water receiving tray 22 from entering the electrical control box 41 through the gap between the heat dissipation opening 4113 and the heat dissipation portion 43. For example, the gap between the heat dissipation opening 4113 and the heat dissipation portion 43 can be sealed using sealant or a sealing ring. It should be noted that the sealing here refers to a relative seal.

[0104] In some embodiments, to prevent water overflowing from the water receiving tray 22 from flowing into the heat dissipation portion 43, referring to Figures 5 and 6, the electronic control assembly 4 further includes a water retaining portion 44, which is disposed outside the heat dissipation portion 43 and is configured to prevent water from flowing into the heat dissipation portion 43. For example, the water retaining portion 44 is disposed on a side of the first plate 4111 facing the water receiving tray 22 and protrudes from an outer surface of the first plate 4111.

[0105] When the housing 1 is in a vertical arrangement, the water retaining portion 44 will be located above the heat dissipating portion 43 to shield the heat dissipating portion 43. In this way, when the water overflowing from the water receiving tray 22 flows on the drainage surface 410 of the box body 411, it can be blocked by the water retaining portion 44 and bypass the heat dissipating portion 43.

[0106] In some embodiments, the water retaining portion 44 is an annular structure, and the water retaining portion 44 is arranged around the periphery of the heat dissipation opening 4113 .

[0107] In other embodiments, the water retaining portion 44 includes a first sub-water retaining portion, a second sub-water retaining portion and a third sub-water retaining portion, the first sub-water retaining portion and the second sub-water retaining portion are connected at one end close to each other, the second sub-water retaining portion and the third sub-water retaining portion are connected at one end close to each other, the first sub-water retaining portion and the third sub-water retaining portion are separated to form an opening, and the opening is arranged away from the water receiving tray.

[0108] For example, the cross section of the water retaining portion 44 may be U-shaped, the water retaining portion 44 is arranged outside the heat dissipation opening 4113 , and the opening is provided on a side of the water retaining portion 44 away from the water receiving tray 22 .

[0109] 6 and 7A , in some embodiments, the box body 411 further includes a first hole 4114 (wire hole) extending through the thickness of the first plate body 4111. Cables coupled to the circuit board 42 within the box body 411 extend through the first hole 4114 to the exterior of the electrical control box 41 for coupling with electrical components of the duct air conditioner 1000.

[0110] In some embodiments, the electronic control assembly 4 further includes a threading portion 46 (e.g., a threading rubber plug), which is disposed at the first hole 4114. The cable coupled to the circuit board 42 extends out of the electronic control box 41 through the threading portion 46. The threading portion 46 seals the gap between the first hole 4114 and the cable, further improving the waterproof performance of the electronic control assembly 4.

[0111] In some embodiments, the electric control box 41 further includes a sealing plate 45 , which covers a side of the first plate body 4111 close to the water receiving tray 22 , and the inclination direction of the sealing plate 45 is the same as the inclination direction of the drainage surface.

[0112] In some embodiments, the heat dissipation portion 43 passes through the sealing plate 45, and at least a portion of the water retaining portion 44 is located outside the sealing plate 45. The heat dissipation portion 43 is sealedly connected to the heat dissipation vent 4113 via the sealing plate 45, thereby utilizing the sealing plate 45 and the water retaining portion 44 to seal the connection between the heat dissipation portion 43 and the heat dissipation vent 4113.

[0113] The setting of the sealing plate 45 can cover the drainage surface 410 of the box body 411, so that the first hole 4114 of the box body 411 and the connection gap between the heat dissipation port 4113 and the heat dissipation part 43 can be covered and sealed by the sealing plate 45, thereby helping to improve the waterproof performance of the electronic control component 4.

[0114] 5 and 6 , the duct air conditioner 1000 further includes a mounting frame 13 (mounting support frame), which is fixedly disposed in the housing 1 and configured to support the fan 3 and the electronic control assembly 4. The fan 3 and the electronic control assembly 4 are disposed on the mounting frame 13.

[0115] In some embodiments, the mounting bracket 13 includes a mounting bracket body 130 and a mounting surface 131 . The mounting surface 131 is located on a side of the mounting bracket body 130 facing the heat exchange assembly 2 .

[0116] In some embodiments, the electronic control assembly 4 and the fan 3 are disposed on the same side of the mounting frame 13. For example, the electronic control assembly 4 and the fan 3 are disposed on the mounting surface 131. In this case, the electronic control assembly 4 and the fan 3 are located between the mounting frame 13 and the heat exchange assembly 2.

[0117] It is understandable that the electric control box 41 of the electric control assembly 4 can cooperate with the mounting surface 131 to form a second cavity.

[0118] In some embodiments, to meet the requirements of fan 3 driving airflow, mounting bracket 13 further includes a vent 132 (ventilation connection port), which is disposed on mounting surface 131. Fan 3 is disposed on mounting surface 131 and communicates with vent 132. The outlet of fan 3 communicates with vent 132 and with air outlet 12.

[0119] In this way, after the fan 3 is started, the air flow outside the shell 1 enters the shell 1 through the air inlet 11 to exchange heat with the heat exchanger 21, then enters the fan 3, is output from the outlet of the fan 3 and the vent 132, and is transported to the outside of the shell 1 through the air outlet 12.

[0120] In some embodiments, to improve the heat dissipation efficiency of the heat dissipation unit 43, the heat dissipation unit 43 of the electric control assembly 4 can be arranged close to the fan 3. For example, the heat dissipation vent 4113 is provided on the side of the electric control box 41 facing the fan 3, and the heat dissipation unit 43 is provided at the heat dissipation vent 4113.

[0121] Thus, after the fan 3 is started, the airflow after heat exchange in the heat exchanger 21 will flow toward the direction of the fan 3 under the drive of the fan 3. During the flow of air, part of the airflow enters the inlet of the fan 3, while the other part of the airflow flows along the outer surface of the first plate 4111 of the electrical control box 41 to remove the heat released by the circuit board 42 absorbed by the heat dissipation portion 43, thereby improving the heat dissipation efficiency of the heat dissipation portion 43.

[0122] In some embodiments, referring to FIG. 3 to FIG. 5 , the duct air conditioner 1000 further includes a flow guide hood 14 , which is disposed at the position of the vent 132 to guide the airflow output from the fan 3 .

[0123] For example, the air guide cover 14 is located between the vent 132 and the air outlet 12 , so that the air flow is easily guided to flow toward the air outlet 12 through the air guide cover 14 .

[0124] In some embodiments, the cross-sectional area of ​​the air guide cover 14 increases along the air outlet direction, which is beneficial to increase the air outlet coverage area of ​​the air outlet 12 and improve the air outlet volume of the air duct unit 1000.

[0125] In other embodiments, the duct air conditioner 1000 further includes a second shielding portion (second shielding plate), which is disposed on the inner wall of the housing 1 and protrudes from and extends obliquely from the inner wall of the housing 1. The second shielding portion is configured to provide water-blocking treatment for the electric control box 41 to improve the waterproof performance of the electric control box 41.

[0126] Here, it should be noted that the second shielding portion can adopt a structure similar to that of the first shielding portion described above, which will not be described in detail here.

[0127] In some embodiments, the second shielding portion is located between the electric control box 41 and the water receiving tray 22 , and a surface of the second shielding portion facing the water receiving tray 22 forms a drainage surface 410 .

[0128] When the housing 1 is in a vertical orientation, the second shielding portion is located below the drain outlet 222 of the water tray 22 and covers the upper edge of the box body 411. Thus, when the water tray 22 overflows, the overflowing water is blocked by the second shielding portion and directed toward the inner wall of the housing 1, flowing down along the inner wall of the housing 1. This improves the waterproof performance of the electrical control box 41.

[0129] The structure of the fan 3 in some embodiments of the present disclosure is introduced below.

[0130] In some embodiments, as shown in FIG8 , the fan 3 includes a volute 31 , and a third cavity is formed inside the volute 31 to accommodate relevant components of the fan 3 (such as an impeller, a motor, and other components).

[0131] In some embodiments, referring to FIG. 9 , the fan 3 further includes an impeller 33 , which is rotatably disposed in the third cavity of the volute 31 .

[0132] 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 .

[0133] 10 , 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 .

[0134] 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.

[0135] In some embodiments, referring to FIG. 9 and FIG. 10 , 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 .

[0136] 9 , the mounting assembly 34 includes a first bracket 341 (a load-bearing bracket) 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.

[0137] 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 .

[0138] 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 .

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] In some embodiments, referring to FIG11 , the first bracket 341 includes a first bracket body 3410 and a bearing portion 3411 (a bearing recess). The 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 within the bearing portion 3411. For example, the bearing portion 3411 is a bearing recess. 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 it from disengaging from the bearing portion 3411.

[0144] It is understood that the arrangement of the bearing 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 bearing portion 3411 first, 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.

[0145] 11 , 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 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.

[0146] 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 .

[0147] In some embodiments, the connecting portion 3412 is detachably mounted on the volute 31 .

[0148] It should be noted that the connecting portion 3412 can be an integral structure with the first bracket body 3410. This facilitates installation and thus improves the assembly efficiency of the fan assembly 3.

[0149] 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.

[0150] In some embodiments, referring to Figures 11 and 12, 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 (insert tongue), which is arranged on both sides of the first bracket body 3410 and located at the first end of the bearing portion 3411.

[0151] 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.

[0152] 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.

[0153] 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.

[0154] It will be appreciated that the screw may pass through the third hole 3422 and be threadedly connected in the second hole 3414 .

[0155] 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.

[0156] In some embodiments, a first clamping portion 3413 and a second hole 3414 are respectively provided on both sides of the carrying portion 3411 , and a second bracket 342 is respectively provided on both sides of the carrying portion 3411 .

[0157] 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.

[0158] In some embodiments, a bearing portion 3411 may be formed on both sides of the first bracket body 341. In this case, the second bracket 342 is connected to both sides of the first bracket 341. This can improve the installation reliability of the motor body 320 and the volute 31.

[0159] In some embodiments, to improve the overall structural strength of the first bracket 341, referring to FIG. 10 , 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 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.

[0160] 13 , 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 .

[0161] For example, a portion of the first shock absorbing portion 322 is located in the 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.

[0162] 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.

[0163] 11 to 13 , the motor 32 further includes a snap ring 323 that is sleeved onto the exterior of the first shock absorbing portion 322. During use, the snap ring 323 is sandwiched 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.

[0164] In some embodiments, referring to FIG. 13 , 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.

[0165] For example, the snap ring 323 is made of a hard material such as metal.

[0166] 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.

[0167] 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 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 bearing portion 3411 is retained in the third limiting portion 3232, thereby improving the installation security of the motor body 320.

[0168] 10 and 12 , the second bracket 342 further includes a second stopper 3423 (blocking portion) disposed on one side of the second bracket body 3420. The second 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.

[0169] 10 , after the second bracket 342 is assembled to the first bracket 341, the second stopper 3423 is located outside the first damping portion 322 and extends toward the first bracket 341. At this time, the first damping portion 322 is located between the second stopper 3423 and the end surface of the motor body 320.

[0170] It is understood that during use, the rotating shaft 321 of the motor 32 will cause the motor body 320 to vibrate while driving the impeller 33. If this vibration is transmitted to the first shock-absorbing portion 322, it may cause the first shock-absorbing portion 322 to deform or shift. By providing the second limiting portion 3423 on the second bracket 342, the outer side of the first shock-absorbing portion 322 can be shielded and limited, ensuring that the first shock-absorbing portion 322 is firmly attached to the end of the motor 32 during use, thereby improving the reliability of the motor.

[0171] 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.

[0172] 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.

[0173] In other embodiments, referring to Figure 14, 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.

[0174] Referring to Figure 14 , 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.

[0175] 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.

[0176] 14 , 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.

[0177] 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.

[0178] 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.

[0179] In some embodiments, referring to FIG. 14 , 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. The mounting groove and vent holes 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.

[0180] 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.

[0181] 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.

[0182] 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.

[0183] In some embodiments, referring to FIG. 15 , the fan 3 includes a volute 31 .

[0184] In some embodiments, the fan 3 further includes an impeller 33 , which is rotatably disposed in the volute 31 .

[0185] In some embodiments, the fan 3 further includes a motor 32 coupled to the impeller 33 and configured to drive the impeller 33 to rotate in the volute 31. The motor 32 includes a motor body 320 and a rotating shaft 321, which is disposed through the impeller 33.

[0186] The difference from the fan 3 described in Figures 8 to 14 is that the motor 32 in Figure 19 also includes multiple mounting parts 324, which are arranged on the outer peripheral surface of the motor body 320 and are spaced apart along the direction surrounding the central axis of the motor body 320.

[0187] 16 , the fan 3 further includes a mounting assembly 34 . The motor 32 is fixed to the housing 1 via the mounting assembly 34 .

[0188] In some embodiments, the mounting assembly 34 includes a plurality of fourth brackets 346 (mounting brackets). The fourth brackets 346 are disposed on at least one of the plurality of 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.

[0189] 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 .

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 17 , in some embodiments, the fourth bracket 346 includes a first arm 3461 (fixed arm) connected to the mounting portion 324 of the motor body 320 and extending along the axial direction of the motor body 320 .

[0196] 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.

[0197] 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 near the mounting portion 324 and extends along the length of the first arm 3461. The first arm 3461 is connected to the mounting portion 324 via the second mating portion 3463.

[0198] During the installation process, the second matching portion 3463 of the first arm 3461 is set on the corresponding 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.

[0199] 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.

[0200] It should be noted that the mounting portion 324 and the second mating portion 3463 can have various structural forms. For example, the 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.

[0201] Alternatively, the 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.

[0202] In some embodiments, referring to FIG. 17 , 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.

[0203] During assembly, the second engaging portion 3463 is first engaged with the mounting portion 324, allowing the first arm 3461 to be mounted on the motor 32. The position of the motor 32 is then adjusted so that the first stop 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, improving the ease and accuracy of assembly.

[0204] 16, 17, and 20, in some embodiments, the second arm 3462 includes a second arm body 34620. The second arm 3462 also includes a fifth hole 34621 (assembly hole) provided in the second arm body 34620. The fifth hole 34621 is provided 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.

[0205] 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.

[0206] 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.

[0207] In some embodiments, referring to FIG. 16 , 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 .

[0208] 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.

[0209] 20 , 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.

[0210] 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.

[0211] 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.

[0212] 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.

[0213] 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.

[0214] 16 and 18 , 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.

[0215] 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.

[0216] 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 .

[0217] In some embodiments, to limit the position of the locking member 349, referring to FIG. 17 , the fourth bracket 346 further includes a first positioning portion 3465 disposed on a side of the first arm 3461 away from the motor body 320. The locking member 349 may 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.

[0218] 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.

[0219] 18 , 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.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] In some embodiments, to facilitate tightening the locking member 349, the locking member 349 further includes two extensions 3492 (bends). The two extensions 3492 are disposed at opposite ends of the locking member body 3490 and extend outward. 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.

[0224] 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.

[0225] 18 , 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.

[0226] 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.

[0227] 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.

[0228] 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.

[0229] 16 , 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 .

[0230] 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.

[0231] 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.

[0232] 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.

[0233] It should be noted that any one of the technical solutions disclosed in the present disclosure can solve one or more of the above-mentioned technical problems and achieve certain invention purposes to a certain extent; multiple technical disclosures can also be combined into an overall solution to solve one or more of the above-mentioned technical problems and achieve certain invention purposes; some of the technical disclosures can also be selected to combine into an overall solution, while adopting related technologies and deteriorated solutions, but the deterioration trend can be compensated by the means disclosed in this technology, and the above-mentioned one or more technical problems can be solved to a certain extent as a whole and certain invention purposes can be achieved; each technical disclosure combined into a complete technical solution constitutes an organic and inseparable overall solution, which solves technical problems as a whole and achieves certain invention purposes.
