[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] In this application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to cool or heat the indoor space.

[0057] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, releasing heat into the surrounding environment through the condensation process.

[0058] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser to a lower-pressure liquid. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves cooling by utilizing the latent heat of evaporation to exchange heat with the material being cooled. Throughout this cycle, the air conditioner regulates the temperature of the indoor space.

[0059] The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

[0060] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0061] like Figures 1-10 As shown, an embodiment of the present application provides a duct air conditioner, including: a shell 1, a heat exchange component 2, a fan 3, an electronic control component 4 and other components.

[0062] The housing 1 serves as an external support and protection body for mounting related components. In order to meet the requirements of air flow and heat exchange, the housing 1 is provided with an air inlet 11 and an air outlet 12.

[0063] The heat exchange assembly 2 is used to perform heat exchange processing on the airflow flowing into the housing 1 to achieve heating and / or cooling of the airflow. The heat exchange assembly 2 includes a heat exchanger 21, which is configured to heat the airflow flowing through it to form a heat exchange airflow.

[0064] Since the condensed water or defrost water generated during the use of the heat exchanger 21 needs to be collected and discharged, the heat exchange assembly 2 further includes a water receiving pan 22, which is arranged at the bottom of the heat exchanger 21 and is used to collect the water left on the heat exchanger 21. The heat exchanger 21 is placed on the water receiving pan 22.

[0065] The fan 3 serves as an airflow driving component. The fan 3 drives the airflow to be introduced through the air inlet 11 , pass through the heat exchanger 21 , and then be sent out from the air outlet 12 .

[0066] The electrical control assembly 4 is mainly used to achieve electrical connection with an external power supply and can also control the operation of the internal electrical components of the duct air conditioner. The electrical control assembly 4 includes an electrical control box 41, which is installed in the housing 1 through the electrical control box 41 as a mounting component of the electrical control assembly 4.

[0067] The electric control assembly 4 further includes a circuit board 42, which is disposed in the electric control box 41. The circuit board 42 is configured with at least one circuit board 42 according to its function to meet power supply and control requirements.

[0068] The heat exchange assembly 2 , the fan 3 and the electric control box 41 are arranged in the housing 1 . Along the airflow direction inside the housing 1 , the heat exchange assembly 2 and the electric control box 41 are arranged in sequence.

[0069] In one embodiment of the present application, in order to facilitate the installation of the fan 3 and the electronic control component 4 to improve assembly reliability and convenience, a support frame 13 is installed to uniformly install and fix the fan 3 and the electronic control component 4 to form a pre-assembled module.

[0070] Specifically, the fan 3 and the electronic control component 4 are respectively installed on the mounting support frame 13. The mounting support frame 13, the fan 3 and the electronic control component 4 are pre-assembled together outside the casing 1 to form a modular structure. Then, they are assembled and fixed in the casing 1 with the help of the mounting support frame 13 to realize the assembly of the fan 3 and the electronic control component 4 into the casing together.

[0071] In one embodiment, in order to facilitate the installation of the mounting support frame 13 into the housing 1 , the mounting support frame 13 can be assembled into the housing 1 in an insertion manner, and second mounting rails 134 are provided on both sides of the mounting support frame 13 .

[0072] Specifically, the housing is provided with a second bearing slot 17, and the mounting support frame 13 is inserted into the second bearing slot 17 via a second mounting rail 134. Thus, during on-site assembly by an operator, the mounting support frame 13, equipped with the fan 3 and the electronic control component 4, is inserted into the second bearing slot 17 via the second mounting rail 134. On the one hand, the mounting support frame 13 is supported by the second bearing slot 17, and on the other hand, the second bearing slot 17 can also limit and fix the mounting support frame 13.

[0073] In one embodiment, to facilitate installation of the heat exchange assembly 2 , first mounting rails 221 are provided on both sides of the water receiving tray 22 . A first bearing slot 18 is provided on the housing 1 , and the first mounting rails 221 are disposed in the first bearing slot 18 .

[0074] Specifically, when the heat exchange assembly 2 is installed in the housing 1 , the first mounting rails 221 on both sides of the water receiving tray 22 are aligned with the first bearing slots 18 and inserted therein, so as to install the heat exchange assembly 2 into the housing 1 in an insertion manner.

[0075] In some embodiments, the housing includes a support frame 15 and a plurality of protective plates 16 , and the protective plates 16 are detachably disposed on the support frame 15 .

[0076] Two oppositely arranged guard plates 16 are provided with a first bearing slot 18 and a second bearing slot 17 , the water receiving tray 22 is inserted into the first bearing slot 18 , and the mounting support frame 13 is inserted between the two oppositely arranged second bearing slots 17 .

[0077] Specifically, when the outer shell 1 is assembled, multiple guard plates 16 are assembled and fixed on the support frame 15. After the guard plates 16 having the first bearing slots 18 and the second bearing slots 17 are fixed on the support frame 15, the mounting support frame 13 and the water receiving tray 2 can be inserted between the two second bearing slots 17, and then the remaining guard plates 16 can be assembled.

[0078] In some embodiments, three adjacent guard plates 16 form a surrounding plate, and another guard plate 16 forms an inspection plate. The housing 1 further includes an end plate 162 .

[0079] Specifically, the cross-section of the enclosure 161 is a U-shaped structure, and two oppositely arranged first bearing slots 18 are respectively provided on the opposite inner side walls of the enclosure 161, and two oppositely arranged second bearing slots 17 are also respectively provided on the opposite inner side walls of the enclosure 161; the inspection plate 163 is detachably provided on the enclosure 161, and the end plate 162 is detachably provided at one end of the enclosure 161.

[0080] The air inlet 11 is provided at one end of the housing 1 , and the air outlet 12 is provided at the other end of the housing 1 . The air outlet 12 is located on one side of the end plate 162 .

[0081] Specifically, the enclosure 161 and the inspection plate 163 are wrapped around the outside of the support frame. During assembly, the enclosure 161 is first connected to the support frame, and then the heat exchange component 2 and the pre-assembled module are respectively inserted into the corresponding bearing slots; then the inspection plate 163 is connected to both sides of the enclosure 161, and the end plate 162 is set at one end of the enclosure 161 to cooperate with the mounting support frame 13 to form a heat dissipation cavity 19.

[0082] In certain embodiments, in order to facilitate maintenance by operators, the inspection panel 163 includes a first plate body 1631 and a second plate body 1632, and the first plate body 1631 and the second plate body 1632 are respectively detachably arranged on the enclosure 161, and the first plate body 1631 is arranged on one side of the pre-assembled module, and the second plate body 1632 is arranged on one side of the heat exchange component 2, and the first plate body 1631 and the second plate body 1632 are docked together.

[0083] Specifically, the inspection panel 163 adopts a split structure, using the first plate body 1631 to meet the maintenance and disassembly requirements of the fan and the electrical control box, and using the second plate body 1632 to meet the maintenance and disassembly requirements of the heat exchange component 2. In this way, during the actual maintenance process, large-scale disassembly and assembly is not required, thereby reducing the difficulty of maintenance.

[0084] In certain embodiments, the inspection plate 163 further includes a refrigerant plate 1633 and a drain plate 1634, the refrigerant plate 1633 is provided with a first hollow structure, the drain plate 1634 is provided with a second hollow structure, the second plate body 1632 is also provided with a first notch and a second notch, the refrigerant plate 1633 and the drain plate 1634 are detachably provided on the enclosure 161, the refrigerant plate 1633 is located in the first notch, and the drain plate 1634 is located in the second notch; the refrigerant pipe of the heat exchanger passes through the first hollow structure, and the drain outlet of the water receiving tray 22 is located in the second hollow structure.

[0085] Specifically, when maintenance is required on the heat exchange assembly 2, since the refrigerant pipe of the heat exchange assembly 2 is connected to the external air conditioner outdoor unit, and the water receiving pan 22 is also connected to a drain pipe, notches are provided at corresponding positions on the second plate 1632 to avoid the refrigerant plate 1633 and the drain plate 1634. In this way, maintenance is not affected by the refrigerant pipe and the drain pipe, thereby reducing the difficulty of maintenance.

[0086] In another embodiment, a mounting support surface 131 is formed on the mounting support frame 13, and a ventilation connection port 132 is further provided on the mounting support surface 131;

[0087] The mounting support frame 13 is disposed in the housing 1 , the electric control box 41 is disposed on the mounting support surface 131 , and the fan 3 is disposed on the mounting support surface 131 and connected to the ventilation connection port 132 ;

[0088] The electric control box 41 and the fan 3 are located between the mounting support frame 13 and the heat exchange assembly 2 .

[0089] Specifically, the mounting support frame 13 is fixedly disposed inside the housing 1 . The mounting support frame 13 will mount and fix the electric control component 4 via the mounting support surface 131 . The electric control box 41 cooperates with the mounting support surface 131 to form a cavity.

[0090] Fan 3 is similarly mounted on mounting support frame 13. To ensure the airflow driven by fan 3, a ventilation connection port 132 is provided on mounting support surface 131. The outlet of fan 3 is connected to ventilation connection port 132. When fan 3 is activated, air enters housing 1 through air inlet 11, exchanges heat with heat exchanger 21 in heat exchange assembly 2, and then enters fan 3. Air is then output from ventilation connection port 132 and delivered to the exterior of housing 1 through air outlet 12.

[0091] In one embodiment, in order to facilitate installation of the fan 3 , the mounting support frame 13 is provided with mounting slots 133 on both sides of the ventilation connection port 132 on the mounting support surface 131 , and the volute of the fan 3 is inserted into the mounting slots 133 .

[0092] Specifically, the volute of the fan 3 can be inserted into the installation slot 133, which can achieve fixed installation on the installation support frame 13 on the one hand, and can also ensure reliable docking between the volute and the ventilation connection port 132 on the other hand.

[0093] In one embodiment of the present application, in order to improve the heat dissipation efficiency of the circuit board 42 in the electrical control box 41, a mounting support frame 13 is provided in the outer shell 1, and a partition 136 is also provided on the mounting support frame 13. A ventilation connection port 132 is provided on the mounting support frame 13, and a first ventilation portion 137 is provided on the partition 136. The partition 136 is arranged on one side of the air outlet 12 and forms a heat dissipation cavity 19 between the mounting support frame 13 and the outer shell 1.

[0094] The heat exchanger, the fan and the electronic control component are arranged in the casing 1 and arranged on a side of the mounting support frame 13 away from the air outlet 12. The fan and the electronic control box are arranged on the mounting support frame 13. The fan is connected to the air outlet 12 through the ventilation connection port 132.

[0095] In addition, the electric control box is provided with a second ventilation portion 401 and a third ventilation portion 402 . The first ventilation portion 137 is connected to the second ventilation portion 401 through the heat dissipation cavity 19 , and the third ventilation portion 402 is located outside the heat dissipation cavity 19 .

[0096] Specifically, in actual use, by setting a partition 136 on the mounting support frame 13, on the one hand, the mounting support frame 13 is used to divide the outer shell 1 into relatively independent cavities, and the fan, heat exchange component 2 and electronic control component are placed in the cavity on one side of the mounting support frame 13, and the partition 136 forms a heat dissipation cavity 19 between the cavity on the other side of the mounting support frame 13 and the outer shell 1.

[0097] During use, after the fan is started, the airflow output from the fan outlet will be directed toward the air outlet 12, pass through the partition 136, and ultimately be output from the air outlet 12. The airflow output from the fan outlet has a relatively high pressure, and can then enter the heat dissipation cavity 19 through the first ventilation portion 137 on the partition 136. The air in the heat dissipation cavity 19 will enter the electrical control box through the second ventilation portion 401, exchange heat with the circuit board, and then flow out through the third ventilation portion 402.

[0098] When the fan is in operation, part of the airflow delivered to the air outlet 12 by the fan enters the heat dissipation cavity 19 through the first ventilation portion 137 .

[0099] When the fan is in operation, the air around the electric control box is sucked into the fan, so that the air in the electric control box flows out through the third vent. At the same time, the air in the heat dissipation cavity 19 flows into the electric control box from the second vent.

[0100] By forming a relatively independent heat dissipation cavity 19 in the casing 1, during the startup of the fan, when the airflow generated by the fan flows toward the air outlet 12, under the action of air pressure, part of the air enters the heat dissipation cavity 19 through the first vent to increase the air pressure in the heat dissipation cavity 19.

[0101] At the same time, the air pressure around the electric control box in the same cavity as the fan is low due to the air suction of the fan. In this way, during the operation of the fan, the air entering the heat dissipation cavity 19 can flow into the electric control box to take away the heat and then be output from the electric control box and circulate into the fan. In this way, the heat dissipation efficiency of the circuit board in the electric control box can be effectively improved.

[0102] In some embodiments, the mounting support frame 13 is provided with a mounting opening 135 , through which the electric control box is mounted.

[0103] The electric control box includes a box body 411 . The circuit board is disposed in the box body 411 . The box body 411 is disposed on the mounting support frame 13 . The box body 411 is located outside the heat dissipation cavity 19 .

[0104] The electric control box includes a box cover 412 , which is detachably disposed on the box body 411 and is located outside the heat dissipation cavity 19 .

[0105] The electric control box includes a maintenance cover 413 , which is disposed on the mounting support frame 13 and is located in the heat dissipation cavity 19 .

[0106] The box body 411 and the maintenance cover 413 both cover the installation opening 135 . The third ventilation portion 402 is provided on the box body 411 , and the second ventilation portion 401 is provided on the maintenance cover 413 .

[0107] Specifically, for the electrical control box, the circuit board 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 box cover 412, and the maintenance cover 413 covers the other side of the installation opening 135 to form a relatively closed electrical control box.

[0108] In some embodiments, the maintenance cover 413 includes a cover plate 4131 and a maintenance plate 4132. The cover plate 4131 is provided with a maintenance opening, and the maintenance plate 4132 is detachably provided on the maintenance opening. The second vent 401 is provided on the cover plate 4131 and / or the maintenance plate 4132.

[0109] Specifically, in order to facilitate later maintenance, the maintenance cover 413 can also be made into a split structure, with maintenance ports corresponding to the positions of easily damaged components on the circuit board set on the cover plate 4131. When maintenance is needed, only the maintenance plate 4132 needs to be removed to perform maintenance.

[0110] In one embodiment of the present application, in order to further improve the heat dissipation efficiency of the circuit board 42 in the electrical control box 41, the electrical control assembly 4 also includes a heat-conducting component 43, which is thermally connected to the circuit board 42. The heat-conducting component is configured to conduct the heat generated by the circuit board to the outside of the electrical control box and dissipate heat with the help of the airflow generated by the fan.

[0111] Specifically, a heat dissipation duct is formed between the electric control box and the fan; the heat conductive component passes through the electric control box, the heat conductive component is thermally connected to the circuit board, and the portion of the heat conductive component extending outside the electric control box is located in the heat dissipation duct.

[0112] Specifically, when the circuit board 42 installed in the box body 411 is powered on and in use, it generates heat, necessitating heat dissipation. A heat-conducting component 43 is provided on the electrical control box 41. The heat-conducting component 43 can be made of a material with excellent thermal conductivity (such as aluminum or copper). The heat-conducting component 43 is inserted into the heat dissipation port 4113 and thermally connected to the circuit board 42, effectively dissipating heat from the circuit board 42.

[0113] The heat dissipation duct formed between the electric control box 41 and the fan 3 can ensure that during the operation of the fan 3, part of the air flow will flow into the heat dissipation duct to quickly and efficiently take away the heat conducted by the heat-conducting component 43, thereby improving the heat dissipation efficiency of the circuit board 42.

[0114] By configuring a heat-conducting component on the electrical control box, the heat-conducting component can pass through the electrical control box and be thermally connected to the circuit board. The heat-conducting component partially extends to the outside of the electrical control box, and then the heat of the circuit board can be conducted to the outside of the electrical control box through the heat-conducting component. The airflow generated by the fan in the outer casing is used to quickly dissipate the heat of the heat-conducting component, thereby improving the heat dissipation efficiency of the electrical control box and improving the reliability of the duct air conditioner.

[0115] In one embodiment, a heat dissipation port 4113 is provided on the electric control box 41, and the heat conducting component 43 is inserted into the heat dissipation port 4113, which, on the one hand, meets the installation requirements of the heat conducting component 43, and on the other hand, satisfies the heat conducting component 43 to conduct the heat generated by the circuit board 42 to the outside of the electric control box 41 via the heat conducting component 43.

In order to improve the heat dissipation efficiency of the heat conducting component 43, the heat conducting component 43 is arranged close to the fan 3.

[0117] Specifically, 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 directly 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-conducting component 43, thereby improving the heat dissipation efficiency of the heat-conducting component 43.

[0118] In one embodiment, a deflector cover 14 is further provided on the ventilation connection port 132 , and the cross-sectional area of ​​the deflector cover 14 increases along the air outlet direction.

[0122] Specifically, to improve the heat dissipation efficiency and operational reliability of circuit board 42, the surface of electrical control box 41 adjacent to the volute of fan 3 is provided with a guide surface 410. This guide surface directs airflow through electrical control box 41. A heat dissipation duct is formed between guide surface 410 and the volute of fan 3. After the fan is started, airflow after heat exchange in the heat exchanger flows toward the fan. Part of the airflow is drawn into the fan, while the remaining airflow passes through the heat dissipation duct and is then drawn back into the fan. This effectively dissipates heat from the circuit board in the electrical control box through the heat dissipation duct.

[0123] In one embodiment, a plurality of heat dissipation fins are provided on the heat conducting component, and the heat dissipation fins are extended and arranged along the rotation axis direction of the fan.

[0124] Specifically, because the heat sink fins are located in the heat dissipation duct, the extension direction of the heat sink fins is the same as the flow direction of the airflow in the heat dissipation duct.

Then, the fixing bracket 342 is pressed onto the motor 32 and a screw is passed through the connecting through hole 3422 and threadedly connected to the screw hole 3414 to complete the assembly.

[0169] The cooperation between the tongue 3413 and the socket 3421 can reduce the number of screws used, thereby improving assembly efficiency.

[0170] In some embodiments, since the supporting bracket 341 is usually made of sheet metal, the supporting bracket 341 is made of sheet metal bending, and supporting grooves 3411 are formed on both sides of the supporting bracket 341, and fixed brackets 342 are connected to both sides of the supporting bracket 341.

[0171] In another embodiment, in order to improve the overall structural strength of the supporting frame, a reinforcement member 344 can be used to connect the two sides of the supporting bracket 341.

The shielding portion 3423 is configured to shield the outside of the first shock-absorbing component 322 to prevent the first shock-absorbing component 322 from detaching from the motor 32.

[0179] Specifically, during use, the rotating shaft 321 of the motor 32 drives the impeller 33 to rotate, causing the motor 32 to vibrate, and the vibration is transmitted to the first shock-absorbing component 322, causing the first shock-absorbing component 322 to deform or shift. The outer side of the first shock-absorbing component 322 is blocked and limited by the blocking portion 3423 on the fixed bracket 342, thereby ensuring that the first shock-absorbing component 322 can be firmly installed at the end of the motor 32 during use without falling off.

The mounting bracket 346 is arranged on the mounting portion 324 and connected to one side of the volute 31, and the auxiliary bracket 343 is arranged on the other side of the volute 31. The free end of the rotating shaft 321 of the motor 32 is rotatably arranged on the auxiliary bracket 343.

[0193] Specifically, a mounting portion 324 is provided on the outer circumference of the motor 32, through which a mounting bracket 346 is assembled. Multiple mounting brackets 346 are provided, and are installed around the exterior of the motor 32 and ultimately connected to the volute 31, thereby meeting the support and installation requirements of the main structure of the motor 32. The rotating shaft 321 of the motor 32, after passing through the impeller 33, is connected to the auxiliary bracket 343, which supports the free end of the rotating shaft 321 of the motor 32.

[0194] In this way, the main structure of the motor 32 is supported and fixed to one side of the impeller 33 by the mounting bracket 346, while the free end of the rotating shaft 321 of the motor 32 on the other side of the impeller 33 is supported by the auxiliary bracket 343. During the transportation of the ducted air conditioner, the main body of the motor 32 is effectively supported and fixed by the mounting assembly 34.

[0195] The multiple mounting brackets 346 can facilitate the operator to adjust the installation position of the motor 32 during assembly, thereby better improving the installation accuracy between the motor 32, the impeller 33 and the volute 31. The multiple mounting brackets 346 can also effectively support and fix the main body of the motor 32 to provide effective support for the motor 32.

[0196] The motor 32 is assisted in being installed on the volute 31 by the installation component 34. The rotating shaft 321 of the motor 32 is connected to the impeller 33 in a penetrating manner. On the one hand, the installation component 34 supports and fixes the main structure of the motor 32 through the installation bracket 346 on one side of the impeller 33. On the other hand, the rotating shaft 321 of the motor 32 is supported and installed through the free end of the impeller 33 by the auxiliary bracket 343 on the other side of the impeller 33. In this way, the motor 32 is effectively supported on both sides of the impeller 33. After the fan 3 is assembled, the impeller 33 can be reliably supported and installed on the rotating shaft 321 of the motor 32.

[0197] During transportation, the motor 32 is reliably supported on both sides of the impeller 33 by installing the assembly 34 to reduce the possibility of the motor 32 being deflected, causing the installation position of the impeller 33 to change, resulting in surge or inaccurate air volume, thereby improving the reliability of the duct machine.

[0198] In one embodiment of the present application, the mounting bracket 346 is an L-shaped structure as a whole. The mounting bracket 346 includes a fixed arm 3461 and a support arm 3462. The support arm 3462 is connected to the end of the fixed arm 3461. The fixed arm 3461 is provided with a mounting fitting portion 3463.

[0199] The fixing arm 3461 extends along the direction of the rotating shaft 321 of the motor 32 , the mounting fitting portion 3463 is provided on the corresponding mounting portion 324 , and the supporting arm 3462 is connected to the volute 31 .

[0200] Specifically, the fixing arm 3461 extends along the outer wall of the housing of the motor 32 and is connected to the mounting portion 324 through the mounting fitting portion 3463, thereby enabling the fixing arm 3461 to be mounted on the motor 32, while the mounting bracket 346 is fixedly connected to the volute 31 through the support arm 3462. The mounting bracket 346 is generally L-shaped, which can both meet the requirements of mounting the motor 32 in the volute 31 through the fixing arm 3461 and fixing the mounting bracket 346 to the volute 31 through the support arm 3462.

[0201] In one embodiment, the mounting portion 324 and the mounting engaging 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 mounting engaging portion 3463 can be a first engaging protrusion formed on the fixed arm 3461, with the first engaging protrusion engaging with the first latching groove. Specifically, the mounting bracket 346 is inserted into the first latching groove via the first engaging protrusion on the fixed arm 3461, thereby securing the mounting bracket 346 to the motor 32.

[0202] Or, for example: the mounting portion 324 is a second clamping protrusion formed on the outer circumference of the motor 32, the mounting matching portion 3463 is a second clamping groove formed on the fixed arm 3461, and the second clamping protrusion is clamped in the second clamping groove.

[0203] In some embodiments, in order to automatically install and position the motor 32, a limiting protrusion 3464 is further provided at the end of the fixed arm 3461 away from the support arm 3462, and the limiting protrusion 3464 is abutted against the end face of the motor 32 away from the support arm 3462.

[0204] Specifically, after the fixing arm 3461 is installed on the motor 32, the position of the motor 32 is adjusted so that the limiting protrusion 3464 abuts against the end face of the motor 32 by the fitting portion 3463 and the mounting portion 324. In this way, the end face of the motor 32 inserted into the volute 31 can be positioned by the limiting protrusion 3464 on the fixing arm 3461, thereby improving the convenience and accuracy of the assembly of the motor 32.

[0205] In some embodiments, an assembly hole is provided on the support arm 3462, and the mounting assembly 34 also includes a shock-absorbing module, which includes a shock-absorbing sleeve 347 and a metal sleeve 348. The shock-absorbing sleeve 347 is provided with a plug-in protrusion 3471, and the shock-absorbing sleeve 347 is also provided with a stepped hole 3472. The stepped hole 3472 includes a first hole section and a second hole section connected together, the diameter of the first hole section is smaller than the diameter of the second hole section, at least part of the first hole section passes through the plug-in protrusion 3471, and the metal sleeve 348 is inserted in the first hole section; the plug-in protrusion 3471 is inserted into the assembly hole, the shock-absorbing sleeve 347 rests on the volute 31, and the connecting bolt passes through the metal sleeve 348 and is fixed to the volute 31 through a connecting nut.

[0206] Specifically, a shock-absorbing sleeve 347 is disposed in the assembly hole of the support arm 3462 of the mounting bracket 346. A metal sleeve 348 is disposed in the stepped hole 3472 formed by the shock-absorbing sleeve 347. When assembled to the volute 31, a connecting bolt passes through the metal sleeve 348 and is connected to the volute 31. The metal sleeve 348 protects the shock-absorbing sleeve 347. The support arm 3462 is connected to the connecting bolt via the shock-absorbing sleeve 347, which provides a good vibration reduction effect, thereby reducing the operating noise of the motor 32.

[0207] The provision of the metal sleeve 348 can limit the size while ensuring effective shock absorption, thereby preventing the impeller 33 of the fan 3 from being installed offset, thereby improving assembly accuracy.

[0208] The end face of the shock-absorbing sleeve 347 is formed with a second hole section, which is in contact with the volute 31. The second hole section does not contact the connecting bolt and forms a buffer zone with the volute 31. The buffer zone is used for the connecting bolt to squeeze the shock-absorbing sleeve 347 to produce a certain amount of compression when the shock-absorbing sleeve 347 is installed. At the same time, in order to prevent the compression of the shock-absorbing sleeve 347 from being too large or too small, a metal sleeve 348 is designed inside the shock-absorbing sleeve 347 to limit the compression of the shock-absorbing sleeve 347, to prevent different compression amounts when multiple shock-absorbing sleeves 347 are installed, thereby causing the rotating shaft 321 of the motor 32 to be eccentric, thereby improving the assembly accuracy and reliability.

After the two ends of the fasteners 349 are connected together, the fasteners 349 will abut against the fixing arms 3461 of the mounting brackets 346, thereby pressing the fixing arms 3461 against the motor 32.

[0211] In one embodiment, in order to position the fastener 349 , a positioning groove 3465 is provided on the fixing arm 3461 of the mounting bracket 346 , and the fastener 349 is located in the positioning groove 3465 .

[0212] Specifically, the fastener 349 can be in a strip-shaped structure.

[0217] In one embodiment, the fastener 349 is in an arc-shaped structure, and a plurality of stress relief holes 3493 are provided on the fastener 349 . The plurality of stress relief holes 3493 are arranged in sequence along the extension direction of the fastener 349 .

[0218] Specifically, stress relief holes 3493 are designed on both sides of the fastener 349 to prevent the circular structure of the fastener 349 from rebounding after production.
