[0032] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0033] Reference below Figure 1-Figure 10 An outdoor unit of an air conditioner according to an embodiment of the present utility model is described.

[0034] The outdoor unit of the air conditioner includes: a casing, a heat exchanger and a fan assembly.

[0035] The casing includes: a shell and a panel, the shell and the panel form an installation cavity, and the heat exchanger and the fan assembly are both arranged in the installation cavity. The casing has an air outlet for discharging air in the casing and an air inlet for sucking air outside the casing, and the air inlet and the air outlet are arranged at intervals. The fan assembly can be arranged opposite to the air outlet. Outdoor air enters the casing from the air inlet and is discharged outdoors from the air outlet after heat exchange in the heat exchanger.

[0036] The outdoor unit of the air conditioner also includes: a compressor, which is provided with an exhaust port and an air return port. The compressor compresses the refrigerant so that the low-pressure refrigerant becomes a high-pressure gaseous refrigerant. The low-pressure refrigerant enters the compressor from the air return port. After the compressor compresses the low-pressure refrigerant into a high-pressure refrigerant, the high-pressure refrigerant is discharged from the exhaust port. The refrigerant releases heat at the condenser, absorbs heat at the evaporator after decompression, and finally enters the compressor from the air return port.

[0037] The heat exchanger is arranged in the casing. Outdoor air enters the casing and can exchange heat with the refrigerant transmitted in the heat exchanger. The outdoor air entering the casing circulates to the heat exchanger to exchange heat with the refrigerant.

[0038] The heat exchanger works as a condenser in the cooling mode of the mobile air conditioner, so that the refrigerant compressed by the compressor condenses by dissipating heat to the outdoor air through the heat exchanger. The heat exchanger works as an evaporator in the heating mode of the mobile air conditioner, so that the decompressed refrigerant absorbs heat from the outdoor air through the heat exchanger and evaporates.

[0039] The arrangement and connection of the compressor and the heat exchanger in the casing can be carried out in any existing manner, which should be known to those skilled in the art. Therefore, in order not to cover up and blur the focus of the present invention, this document does not specifically limit or describe in detail the arrangement position and connection method of the compressor and the heat exchanger.

[0040] The fan assembly is arranged in the installation cavity, and is used to drive the airflow to flow through the heat exchanger for heat exchange. The fan assembly is located in the casing. Driven by the fan assembly, outdoor air enters the casing from the outside and flows to the heat exchanger. After the outdoor air exchanges heat with the refrigerant at the heat exchanger, the refrigerant is discharged to the outside under the drive of the fan assembly.

[0041] like Fig.10 As shown, the fan assembly includes: a fan 20. Specifically, the fan assembly includes: a fan and a fan 20, the fan and the fan 20 are transmission-connected, and the fan drives the fan 20 to rotate, so that outdoor air continuously enters the interior of the shell and flows to the heat exchanger, so that the outdoor air exchanges heat with the refrigerant at the heat exchanger, so as to realize the operation of the outdoor unit of the air conditioner.

[0042] The fan 20 includes a hub 22, which is connected to the fan in a transmission manner. The hub 22 is arranged radially outward from the center and is generally cylindrical. The hub 22 is connected to the fan, and when the fan drives the hub 22 to rotate, the fan 20 rotates with the hub 22.

[0043] The fan 20 further includes: a plurality of blades 21, which are arranged at intervals around the outer circumference of the hub 22 and are fixedly connected to the hub 22. Specifically, the number of the blades 21 is at least two, and at least two blades 21 are arranged at intervals around the outer circumference of the hub 22. The hub 22 and the blades 21 are arranged coaxially, which can ensure that the inflow and outflow of the fan 20 are balanced during operation.

[0044] The surface of the negative pressure side of the fan blade 21 is the suction surface, and the surface of the positive pressure side of the fan blade 21 is the pressure surface.

[0045] Combination Figure 1-Figure 10 As shown, the outdoor unit of the air conditioner also includes: an air guide 10, the air guide 10 is arranged in the installation cavity, and the air guide 10 is fixedly connected to the panel. The air guide 10 is roughly cylindrical, and the air guide 10 has an outer peripheral edge radially outward and an inner peripheral edge radially inward. The inner peripheral edge of the air guide 10 is circular, and the outer peripheral edge can be wavy or zigzag. The air guide 10 and the fan 20 are relatively arranged, and the fan 20, under the drive of the fan, discharges the air after heat exchange in the outdoor unit of the air conditioner from the air guide 10 to the outdoors.

[0046] The air guide 10 has an air inlet end and an air outlet end, and an air passage connecting the air inlet end and the air outlet end, and the fan assembly is arranged in the air passage. Specifically, the air inlet end of the air guide 10 is arranged toward the fan assembly, and the air outlet end of the air guide 10 is arranged away from the fan assembly. Part of the fan assembly is located in the air passage, and the air blown out from the fan 20 flows to the outside through the air guide 10. Since the inner circumference of the air guide 10 is larger than the outer circumference of the fan 20, a gap is arranged between the fan 20 and the air guide 10.

[0047] It should be noted that the blade tip vortex refers to: when the fan 20 rotates, there is a pressure difference between the pressure surface and the suction surface of the blade 21 of the fan 20, so that the airflow on the pressure surface leaks over the outer edge of the blade 21 to the suction surface, and the leakage airflow and the main airflow are sucked together to form a vortex. The blade tip vortex will block the main airflow flow channel, and the blade tip vortex and the main airflow collide to easily generate noise, thereby reducing the air volume of the air conditioner outdoor unit and increasing the noise.

[0048] like Figure 1-Figure 5As shown, the air inlet end of the air guide 10 is provided with a plurality of spoilers 11, and the plurality of spoilers 11 are arranged around the circumference of the air guide 10. The spoilers 11 may be wavy, and the wavy spoilers 11 may break up the tip vortex generated by the gap between the fan 20 and the air guide 10, and reduce the vortex intensity of the tip vortex. Since the tip vortex directly affects the size of the BPF discrete noise, the effect of reducing the BPF noise may be achieved.

[0049] In some other embodiments, the spoiler 11 may be serrated. The spoiler 11 is serrated, which can break up the tip vortex generated by the gap between the fan 20 and the air guide 10, reduce the vortex intensity of the tip vortex, and because the tip vortex directly affects the size of the BPF discrete noise, the effect of reducing the BPF noise can be achieved.

[0050] Therefore, the wavy or sawtooth-shaped spoiler 11 can interfere with the tip vortex. Therefore, the spoiler 11 is set at the air inlet end of the air guide 10, which can make the air guide 10 disturb and destroy the vortex state of the tip vortex, and make the airflow originally in the vortex state flow outward in a turbulent form, thereby avoiding obstruction to the main airflow and preventing impact with the main airflow, thereby increasing the air outlet volume and reducing noise.

[0051] like Figure 6 As shown, in the axial direction of the air guide 10, the size of the spoiler 11 is h, and h satisfies the relationship: 5mm≤h≤30mm. Specifically, in the axial direction of the air guide 10, the amplitude range of the spoiler 11 is between 5mm-30mm, ensuring that the spoiler 11 can cut the tip vortex into turbulence, avoid blocking the main airflow, prevent impact with the main airflow, thereby increasing the air volume and reducing noise.

[0052] If the amplitude of the spoiler 11 is less than 5 mm, the effect of the spoiler 11 in cutting the blade tip vortex is not good. In order to ensure the noise reduction effect of the spoiler 11, the dimension h of the spoiler 11 in the axial direction of the air guide 10 is set to be not less than the first parameter value, and the first parameter value can be 8 mm, 10 mm, or 12 mm. Consider selecting a suitable value in the specific design.

[0053] If the amplitude of the spoiler 11 is greater than 30 mm, in the axial direction of the air guide 10, the end of the spoiler 11 away from the air outlet protrudes from the end of the fan 20, and the tip vortex does not pass through the spoiler 11, and the spoiler 11 cannot play the effect of cutting the tip vortex. In order to ensure the noise reduction effect of the spoiler 11, the size h of the spoiler 11 in the axial direction of the air guide 10 is set to be no greater than the second parameter value, and the second parameter value can be 18 mm, 21 mm, or 25 mm. Consider selecting a suitable value in the specific design.

[0054] Reference Figure 1-Figure 10As shown, the distance between two adjacent spoilers 11 is L, and L satisfies the relationship: 0m≤L≤50mm.

[0055] like Figure 1-Figure 3 As shown, the distance between two adjacent spoilers 11 can be 0 mm, that is, the two adjacent spoilers 11 are arranged closely together, and the peripheries of the plurality of spoilers 11 form a continuous wave shape to disrupt the airflow flowing from the pressure surface to the pressure surface and reduce the noise generated by the fan 20.

[0056] like Figure 4 and Figure 5 As shown, two adjacent spoilers 11 are arranged at intervals, and the interval between two adjacent spoilers 11 is between 0-50 mm, so as to ensure that the spoilers 11 can cut the blade tip vortex and achieve the effect of noise reduction.

[0057] In some embodiments, the distances between any two adjacent spoilers 11 may not be completely consistent.

[0058] If the spacing between two adjacent spoilers 11 is greater than 50 mm, the spacing between the two adjacent spoilers 11 is too large, resulting in the spoiler 11 being unable to cut the tip vortex, and the noise reduction effect is not obvious. In order to ensure the noise reduction effect of the spoiler 11, the spacing L between two adjacent spoilers 11 is set not to exceed the third parameter value, and the third parameter value can be 20 mm, 30 mm, or 40 mm. Consider selecting a suitable value in the specific design.

[0059] Specifically, the waveform of the spoiler 11 is not limited, and can be an arc, an ellipse, a triangle, a parabola, or a Bezier line. The spoiler 11 can also be a combination of two, three, four, or five of the following: a circle, an ellipse, a triangle, a parabola, or a Bezier line.

[0060] The arc-shaped, elliptical, triangular, parabolic or Bessel-shaped spoiler 11 can disrupt the airflow flowing from the pressure surface to the pressure surface, so as to cut the blade tip vortex into turbulence and reduce the noise generated by the rotation of the fan 20.

[0061] The air guide 10 includes: a first air guide portion 12, and the first air guide portion 12 is connected to the panel. That is, one side of the first air guide portion 12 is connected to the peripheral side of the air outlet on the panel; the first air guide portion 12 and the second air guide portion 13 form an air passage, and the airflow in the housing flows from the air passage to the outside.

[0062] The air guide 10 further includes: a second air guide portion 13, the second air guide portion 13 is connected to the side of the first air guide portion 12 facing away from the panel, and a spoiler 11 is provided on the side of the second air guide portion 13 facing away from the first air guide portion 12. Specifically, one side of the second air guide portion 13 is connected to the side of the first air guide portion 12 facing away from the panel, and the other side of the second air guide portion 13 is provided with a spoiler 11, and a plurality of spoilers 11 are provided around the circumference of the other side of the second air guide portion 13.

[0063] like Fig.10 As shown, let A be the plane passing through the midpoint of the hub 22 and perpendicular to the axial direction of the air guide 10, and let B be the plane on the side of the hub 22 facing away from the panel; let C and D be the two ends of the spoiler 11 in the circumferential direction; in the axial direction of the air guide 10, C and D are both arranged between A and B. Specifically, along the axial direction of the air guide 10, the end of the spoiler 11 facing the panel is located between the midpoint of the hub 22 and the end of the hub 22 close to the panel, then the spoiler 11 can cut the airflow flowing from the pressure surface to the suction surface to achieve the effect of noise reduction.

[0064] If the end of the spoiler 11 facing the panel is not located between the midpoint of the hub 22 and the end of the hub 22 on the side close to the panel, the airflow flowing from the pressure surface to the suction surface does not flow through the spoiler 11, and the spoiler 11 cannot cut the tip vortex and cannot achieve the noise reduction effect.

[0065] In some embodiments, the distance between the spoiler 11 and the outer edge of the fan 20 gradually increases in the direction away from the panel. In other words, the spoiler 11 is gradually expanded in the direction away from the panel, so when the airflow on the pressure surface flows to the suction surface, the spoiler 11 can guide the airflow, and guide the airflow to the end of the spoiler 11 on the side close to the panel, so that the end of the spoiler 11 can cut the airflow, thereby achieving a noise reduction effect.

[0066] In some embodiments, the cross section obtained by cutting the spoiler 11 with a plane composed of the radial and axial directions of the air guide 10 is an arc. That is, the surface of the spoiler 11 facing the fan 20 is an arc surface. In the direction away from the panel, the spoiler 11 is trumpet-shaped, and the transition of the spoiler 11 is smooth, so that the airflow flowing from the pressure surface to the suction surface smoothly transitions on the inner side of the spoiler 11, so that the spoiler 11 has a better effect of cutting the blade tip vortex and a better noise reduction effect.

[0067] In some embodiments, an air outlet is provided on the panel, and a connecting flange is provided at the air outlet end, and the air outlet end is connected to the edge of the panel at the air outlet through the connecting flange. Specifically, one end of the connecting flange is connected to the end of the air guide 10 facing the panel, and one end of the connecting flange is connected to the peripheral side of the air outlet, and the connecting flange connects the air guide 10 and the panel. Thus, the air guide 10 and the panel are connected as a whole through the connecting flange. This structure is simple and easy to implement.

[0068] According to the second aspect of the present invention, the outdoor unit of the air conditioner comprises: a casing, a heat exchanger and a fan assembly.

[0069] The casing includes: a shell and a panel, the shell and the panel form an installation cavity, and the heat exchanger and the fan assembly are both arranged in the installation cavity. The casing has an air outlet for discharging air in the casing and an air inlet for sucking air outside the casing, and the air inlet and the air outlet are arranged at intervals. The fan assembly can be arranged opposite to the air outlet. Outdoor air enters the casing from the air inlet and is discharged to the outside from the air outlet after heat exchange in the heat exchanger.

[0070] The fan assembly is arranged in the installation cavity and is used to drive the air flow to flow through the heat exchanger for heat exchange.

[0071] The fan assembly includes: a fan 20. Specifically, the fan assembly includes: a fan and a fan 20, the fan and the fan 20 are transmission-connected, and the fan drives the fan 20 to rotate, so that outdoor air continuously enters the interior of the shell and flows to the heat exchanger, so that the outdoor air exchanges heat with the refrigerant at the heat exchanger, so as to realize the operation of the outdoor unit of the air conditioner.

[0072] The outdoor unit of the air conditioner further comprises: an air guide 10, which is arranged in the installation cavity and fixedly connected to the panel. The air guide 10 is roughly cylindrical. The air guide 10 and the fan assembly are arranged relative to each other, and the fan 20, driven by the fan, discharges the air after heat exchange in the outdoor unit of the air conditioner from the air guide 10 to the outside.

[0073] The air guide 10 has an air inlet end and an air outlet end, and an air passage connecting the air inlet end and the air outlet end, and the fan assembly is arranged in the air passage. Specifically, the air inlet end of the air guide 10 is arranged toward the fan assembly, and the air outlet end of the air guide 10 is arranged away from the fan assembly. Part of the fan assembly is located in the air passage, and the air blown out from the fan 20 flows to the outside through the air guide 10. Since the inner circumference of the air guide 10 is larger than the outer circumference of the fan 20, a gap is arranged between the fan 20 and the air guide 10.

[0074] In some other embodiments, the air guide 10 and the panel are integrally formed. The air guide 10 and the panel are integrally formed. In this way, the number of parts included in the air conditioner outdoor unit can be reduced, and the assembly complexity of the air conditioner outdoor unit can be reduced.

[0075] Other structures of the air conditioner outdoor unit of the embodiment of the utility model are well known to those skilled in the art and will not be described in detail here.
