Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioning, and in particular relates to a ceiling air conditioner. Background Art

[0002] Embedded ceiling air conditioners are mainly used in large venues such as offices, classrooms, and shopping malls. They have the advantages of small footprint and good cooling / heating effects, and are favored by users. The ceiling air conditioner includes a casing, which is provided with an air inlet and multiple air outlets. The casing is provided with an indoor heat exchanger and an indoor fan, so that air flows out from each air outlet of the ceiling air conditioner.

[0003] In the prior art, the indoor fan includes a motor and a wind wheel. The motor is installed on the chassis of the housing. The wind wheel is a centrifugal wind wheel and is connected to the motor. In order to ensure the strength of the chassis, a number of reinforcing ribs are provided on the chassis to reduce chassis vibration. At the same time, a reasonable gap needs to be set between the wind wheel and the chassis to meet the requirements of the protection experiment.

[0004] However, the gap between the wind wheel and the chassis and the uneven reinforcement ribs on the chassis will affect the wind field at the bottom of the wind wheel, causing local backflow. The appearance of backflow increases the noise value of the whole machine and affects the air volume of the whole machine, which is not conducive to improving the user experience.

[0057] The ceiling air conditioner performs the refrigeration cycle of the ceiling air conditioner by using a compressor, a condenser, a throttling device and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat exchanged. Among them, the ceiling air conditioner includes a ceiling unit (i.e., the indoor unit of the ceiling air conditioner) and an air conditioner outdoor unit (i.e., the outdoor unit of the air conditioner).

[0058] The utility model proposes a ceiling machine 100, which is shown below. Figures 1 to 20 A ceiling machine 100 is described, wherein: Figure 1 to Figure 3 1 is an appearance diagram of a ceiling unit 100. The ceiling unit 100 is an indoor unit part of a ceiling unit air conditioner. In addition, the ceiling unit air conditioner also includes an outdoor unit.

[0059] refer to Figure 1 In an exemplary embodiment of the ceiling machine 100 of the present invention, the ceiling machine 100 may include a housing 1. The housing 1 forms the overall appearance of the ceiling machine 100.

[0060] The housing 1 is in a cubic shape, and a mounting cavity is formed inside the housing 1. The mounting cavity is used to accommodate and fix various components in the ceiling machine 100 to ensure the structural stability of the ceiling machine 100.

[0061] The casing 1 can protect various components inside the casing 1, thereby extending the service life of the ceiling machine 100.

[0062] In some embodiments of the present application, the housing 1 may include an air inlet 13. The air inlet 13 is connected to the installation cavity, and the air inlet 13 serves as an inlet for the external air of the housing 1 to flow into the installation cavity, allowing the indoor air to enter the installation cavity through the air inlet 13.

[0063] In some embodiments of the present application, the housing 1 may include a plurality of air outlets 14 . The plurality of air outlets 14 are arranged around the air inlet 13 .

[0064] The air outlet 14 is communicated with the installation cavity, and serves as an outlet for the heat exchange airflow in the housing 1 to flow out, allowing the airflow in the installation cavity to flow out through a plurality of air outlets 14 .

[0065] In some embodiments of the present application, the housing 1 may include a box body 11. The box body 11 is suitable for being installed between a ceiling and a suspended ceiling, and the bottom end of the box body 11 is open.

[0066] In some embodiments of the present application, the housing 1 may include a panel 12. The panel 12 is connected to the open end of the box body 11 to cover the open end of the box body 11, thereby shielding the box body 11, and the panel 12 cooperates with the box body 11 to define the above-mentioned installation cavity.

[0067] The box body 11 is in the shape of a cube.

[0068] In some embodiments of the present application, an air inlet 13 and a plurality of air outlets 14 are opened on the panel 12 .

[0069] The air inlet 13 is arranged in the middle of the panel 12, and a plurality of air outlets 14 are arranged around the air inlet 13. This arrangement allows the ceiling machine 100 to take in air from the air inlet 13 in the middle of the panel 12 and blow it out toward the air outlets 14 on the surrounding sides when the ceiling machine 100 is in operation, so that the heat exchange airflow after heat exchange flows into the room from multiple directions, thereby increasing the air output of the ceiling machine 100.

[0070] In some embodiments of the present application, reference Figure 2 , Figure 4 The ceiling machine 100 proposed in the present invention is a four-air outlet ceiling machine, that is, an air inlet 13 and four air outlets 14 are provided on the panel 12 .

[0071] The air inlet 13 is a square air inlet 13 , and the four air outlets 14 are all arranged in a strip shape. The four air outlets 14 are arranged along the extension direction of the four sides of the panel 12 respectively.

[0072] In some embodiments of the present application, an air inlet grille 15 is provided at the air inlet 13. The air inlet grille 15 is connected to the housing 1 and is used to filter the indoor air entering the housing 1 to prevent larger impurities from entering the housing.

[0073] In some embodiments of the present application, the panel 12 is arranged in a square shape to match the open end of the box body 11 .

[0074] In some embodiments of the present application, the panel 12 may extend outside the box body 11 , thereby improving the aesthetics of the ceiling machine 100 and improving the integrity of the ceiling machine 100 .

[0075] When the ceiling machine 100 is installed, the panel 12 is roughly flush with the bottom surface of the ceiling, so that the panel 1212 and the ceiling form an integral structure. The panel 12 hides the box 11 between the ceiling and the ceiling, ensuring that the ceiling machine 100 can vent air while making the overall appearance better.

[0076] In some embodiments of the present application, the length dimension of the panel 12 may be greater than the length dimension of the opening of the box 11 , and the width dimension of the panel 12 may be greater than the width dimension of the opening of the box 11 , so that the panel 12 can completely cover the opening of the box 11 .

[0077] The panel 12 covers the opening at the bottom of the box 11 , which improves the aesthetics of the ceiling machine 100 . On the other hand, the bottom of the box 11 is fixed to the ceiling by being installed with the panel 12 .

[0078] In some embodiments of the present application, ends of the panel 12 extend beyond the box body 11, so that the connection area between the panel 12 and the ceiling is larger. The panel 12 is installed on the ceiling and the box body 11 respectively, further ensuring the assembly firmness of the ceiling machine 100.

[0079] In some embodiments of the present application, the ceiling machine 100 may include an indoor heat exchanger 2. The indoor heat exchanger 2 is disposed in the casing 1.

[0080] In some embodiments of the present application, the ceiling machine 100 may include an indoor fan. The indoor fan is arranged in the housing 1, and the indoor fan is located in the middle of the installation cavity.

[0081] The indoor heat exchanger 2 is disposed outside the indoor fan and is used to absorb heat from the indoor wind in the installation cavity or transfer heat to the indoor wind in the installation cavity.

[0082] The indoor fan is arranged corresponding to the air inlet 13 to drive the indoor wind to enter the installation cavity through the air inlet 13, so that the air flow can flow from the air inlet 13 to the air outlet 14.

[0083] refer to Figure 5 In some embodiments of the present application, the indoor heat exchanger 2 is configured to surround the indoor fan and is bent into a quadrilateral shape, and the indoor heat exchanger 2 is close to the air outlet 14 relative to the indoor fan.

[0084] When the ceiling machine 100 is in operation, driven by the indoor fan, the indoor air enters the installation cavity through the air inlet 13, the indoor air in the installation cavity flows through the indoor heat exchanger 2 for heat exchange, and the heat exchange air flows outwardly into the room through the air outlet 14, thereby making the ceiling machine cool and heat, playing the role of regulating the indoor temperature to achieve a comfortable temperature for the user.

[0085] The ceiling air conditioner has a refrigerant circuit that sequentially connects a compressor, a condenser, a throttling device, and an evaporator in an annular manner to circulate the refrigerant.

[0086] The air conditioner outdoor unit refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The compressor is arranged in the outdoor housing 1. The compressor compresses the refrigerant gas in the low-temperature and low-pressure state and discharges the refrigerant gas in the high-temperature and high-pressure state. The throttling device can be provided in the ceiling unit or the outdoor unit. The throttling device expands the liquid phase refrigerant in the high-temperature and high-pressure state condensed in the condenser into a low-pressure liquid phase refrigerant.

[0087] Among them, among both the indoor heat exchanger and the outdoor heat exchanger, one is a condenser and the other is an evaporator.

[0088] The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled.

[0089] The ceiling air conditioner includes a cooling mode and a heating mode. In the cooling mode, the indoor heat exchanger is an evaporator, the outdoor heat exchanger is a condenser, and the refrigerant circulates through the compressor, the outdoor heat exchanger, the throttling device, and the indoor heat exchanger in sequence. In the heating mode, the indoor heat exchanger is a condenser and the outdoor heat exchanger is an evaporator, and the refrigerant circulates through the compressor, the indoor heat exchanger, the throttling device, and the outdoor heat exchanger in sequence to achieve the air conditioning function.

[0090] In some embodiments of the present application, the ceiling machine 100 may include a water receiving tray 5. The water receiving tray 5 is connected to the open end of the box body 11.

[0091] The water receiving pan 5 is located below the indoor heat exchanger 2 so as to receive and collect the condensed water of the indoor heat exchanger 2 .

[0092] In some embodiments of the present application, the water receiving pan 5 is arranged in the installation cavity and located at the bottom of the installation cavity, and the bottom end of the indoor heat exchanger 2 abuts against the water receiving pan 5, so that the condensed water generated by the indoor heat exchanger 2 drips into the water receiving pan 5 for collection.

[0093] In some other embodiments of this application, continue to refer to Figure 5 The ceiling machine 100 further includes an air guide ring 16. The air guide ring 16 is arranged corresponding to the air inlet 13, so that the airflow can enter the housing 1 through the air inlet more stably and accurately.

[0094] In some other embodiments of the present application, the box body 11 may include a bottom plate 111. The bottom plate 111 is arranged opposite to the panel.

[0095] In some other embodiments of this application, refer to Figure 6 to Figure 10 The indoor fan may include a wind wheel 4. The wind wheel 4 is usually a centrifugal wind wheel 50.

[0096] In some other embodiments of the present application, the indoor fan may include a motor 3. The motor 3 is disposed on a side of the chassis 111 close to the panel 12, and the wind wheel 4 is connected to the motor 3 so that the motor 3 drives the wind wheel 4 to rotate.

[0097] In some other embodiments of the present application, a motor mounting portion 17 is provided on the chassis 111 , and the motor 3 is installed at the motor mounting portion 17 .

[0098] In some other embodiments of the present application, the ceiling machine 100 may include a plurality of reinforcing ribs 6 .

[0099] refer to Fig.13 A plurality of reinforcing ribs 6 are provided on the side of the chassis 111 facing the indoor fan.

[0100] By providing a plurality of reinforcing ribs 6, the strength of the chassis 111 is improved, thereby preventing the chassis 111 from shaking or vibrating due to resonance when the ceiling machine 100 is working.

[0101] In the related art, the gap between the wind wheel 4 and the chassis 111 and the uneven reinforcement ribs 6 on the chassis 111 will affect the wind field at the bottom of the wind wheel 4, causing local backflow, increasing the noise of the whole machine and affecting the air volume. Fig.19 Select the part with red frame.

[0102] In some other embodiments of the present application, the ceiling machine 100 may include a rectifying plate 8 .

[0103] refer to Fig. 9 , Fig.10 The rectifier plate 8 is arranged on one side of the chassis 111 close to the wind wheel.

[0104] refer to Fig.11 The rectifier plate 8 is covered on a plurality of reinforcing ribs 6 .

[0105] In some other embodiments of the present application, the rectifier plate 8 is spot-welded to the side of the chassis 111 facing the wind wheel 4 .

[0106] refer to Fig.11 By welding the rectifier plate 8 to the chassis 111, the strength of the chassis 111 is improved, and the vibration of the chassis 111 due to resonance when the ceiling machine 100 is working is effectively avoided.

[0107] In some other embodiments of the present application, the ceiling machine 100 may include at least two annular ribs 9. At least two annular ribs 9 are formed at intervals on the side of the rectifier plate 8 facing the wind wheel 4.

[0108] refer to Fig.10 At least two annular ribs 9 are coaxially arranged with the wind wheel 4 .

[0109] refer to Fig.10 The outer diameter of the annular rib is smaller than the diameter of the wind wheel. This arrangement enables all the annular ribs to be located in the plane corresponding to the bottom surface of the wind wheel.

[0110] The strength of the chassis 111 is enhanced by providing the rectifier plate 8. By providing two annular ribs 9 on the rectifier plate 8, the wind field between the bottom surface of the wind wheel 4 and the chassis 111 can be effectively blocked to prevent backflow, thereby making the wind field in the housing 1 smoother, thereby reducing the noise value and increasing the air volume.

[0111] refer to Fig. 20 , which is a wind field simulation diagram inside the ceiling machine 100 provided in this embodiment, from Fig. 20 It can be seen from the figure that the backflow between the bottom of the wind wheel 4 and the chassis 111 is significantly reduced.

[0112] In some other embodiments of the present application, the annular rib 9 is formed by the rectifier plate 8 protruding toward the indoor fan. At least two annular ribs 9 are arranged at intervals, and at least two annular ribs 9 are arranged coaxially with the wind wheel 4.

[0113] refer to Fig.13 The annular rib 9 is formed by the rectifier plate 8 protruding toward the wind wheel 4, which is simple and convenient. This arrangement enables the annular rib 9 to be integrally formed with the rectifier plate 8, which is convenient for processing and manufacturing.

[0114] In some embodiments of the present application, a avoidance portion 82 is provided in the middle portion of the rectifier plate 8 corresponding to the motor mounting portion 17 .

[0115] refer to Fig.14 The setting of the avoidance portion 82 avoids the installation of the motor 3, so that the motor 3 passes through the avoidance portion 82 and is installed at the motor installation portion 17.

[0116] In some embodiments of the present application, the ceiling machine 100 may include a wiring groove 7. The wiring groove 7 is formed on the side of the chassis 111 facing the wind wheel 4.

[0117] refer to Fig.15 The cable is passed through the wiring groove 7 formed on the chassis 111 to connect the cable to the motor 3, thereby realizing the transmission of power supply and control signals. The cable of the motor 3 can be routed along the wiring groove 7, so that the cable is neatly fixed on the chassis 111 of the ceiling machine 100.

[0118] In some embodiments of the present application, a notch 81 is provided on the rectifier plate 8. The notch 81 is opened corresponding to the wiring groove 7 to facilitate the wiring of the cables.

[0119] In some embodiments of the present application, the number of the annular ribs 9 is configured to be 2 to 5.

[0120] refer to Fig.16 , Fig.17 , exemplarily, in this embodiment, the number of the annular ribs 9 is 3.

[0121] In some embodiments of the present application, reference Fig.18 , the thickness of the rectifier plate 8 is c. 0.6mm≤c. c. ≤0.8mm.

[0122] The thickness of the rectifier plate 8 is too small, resulting in the rectifier plate 8 being too thin, which is not conducive to enhancing the strength of the chassis 111. In order to effectively improve the strength of the chassis 111 and facilitate the manufacture of the rectifier plate 8, the thickness of the rectifier plate 8 is set to be greater than or equal to the first parameter value. For example, the first numerical parameter can be 0.6 mm, 0.65 mm, or 0.68 mm. Consider selecting a suitable and specific parameter in the specific design.

[0123] The thickness of the rectifier plate 8 is too large, which makes the rectifier plate 8 too thick, which is not conducive to cost saving. In order to effectively reduce the cost of the whole machine and avoid unnecessary waste of materials, the thickness of the rectifier plate 8 is set to be less than or equal to the second parameter value. For example, the second numerical parameter can be 0.8mm, 0.78mm, or 0.75mm. Consider selecting a suitable and specific parameter in the specific design.

[0124] In some embodiments of the present application, the thickness of the rectifying plate 8 is c: 0.6 mm ≤ c ≤ 0.8 mm.

[0125] The thickness of the rectifier plate 8 is set to any value between 0.6 mm and 0.8 mm, which effectively saves costs while increasing the strength of the chassis 111. At the same time, the rectifier plate 8 can be manufactured using standard sheet metal parts, which is simple and convenient.

[0126] In some embodiments of the present application, in the thickness direction of the rectifying plate 8, the height dimension of the annular rib 9 is h.5mm≤h.h≤8mm.

[0127] If the height dimension of the annular rib 9 is too large, the distance between the annular rib 9 and the wind wheel 4 will be too close. When there is an upward or downward offset or error in the installation of the wind wheel 4, the annular rib 9 will damage the wind wheel 4. In order to prevent the annular rib 9 from colliding with the wind wheel 4 due to excessive height, the height dimension h of the annular rib 9 can be set to be no greater than the third parameter value. For example, the third parameter value h can be 8 mm, 7.5 mm, or 7 mm. Consider selecting a suitable and specific parameter in the specific design.

[0128] If the height dimension of the annular rib 9 is too small, the annular rib 9 has a small blocking effect on the airflow in the wind farm. In order to improve the blocking effect of the annular rib 9 on the airflow, the height dimension h of the annular rib 9 is set to be not less than the fourth parameter value. For example, the fourth parameter value can be 5mm, 5.5mm, or 6mm. Consider selecting a suitable specific parameter in the specific design.

[0129] In some embodiments of the present application, in the thickness direction of the rectifying plate 8, the height dimension of the annular rib 9 is h.5 mm ≤ h.h ≤ 6.5 mm.

[0130] The height of the annular rib 9 is set to any value between 5 mm and 6.5 mm. The annular rib 9 within this height range can block the airflow and more effectively avoid interfering with the rotation of the wind wheel 4, thereby increasing the service life of the whole machine.

[0131] In some embodiments of the present application, in the thickness direction of the rectifying plate 8, the height dimension of the annular rib 9 is h, 6.5 mm ≤ h, h ≤ 8 mm.

[0132] The height of the annular rib 9 is set to any value between 6.5 mm and 8 mm. The annular rib 9 within this height range ensures that it will not interfere with the wind wheel 4, while being more inclined to retain its performance of blocking the wind field, effectively reducing the noise value of the whole machine and effectively increasing the air volume.

[0133] In some embodiments of the present application, in the thickness direction of the rectifying plate 8, the height dimension of the annular rib 9 is h: 5mm≤h≤8mm.

[0134] The height of the annular rib 9 is set to any value between 5 mm and 8 mm, so that the annular rib 9 can block the wind field between the wind wheel 4 and the chassis 111, prevent backflow, and avoid damaging the wind wheel 4.

[0135] In some embodiments of the present application, the width of the outer annular rib 9 of at least two annular ribs 9 is greater than the width of the other annular ribs 9 , and the outer annular rib 9 is farther away from the central axis of the indoor fan than the other annular ribs 9 .

[0136] The airflow at the outer annular rib 9 is larger than that at other annular ribs 9. By setting the width of the outer annular rib 9 to be larger than that of other annular ribs 9, the width of the outer annular rib 9 is made wider, which can effectively block the outer airflow and prevent backflow.

[0137] The arrangement of other annular ribs 9 can block the outer airflow that is not blocked by the outer annular ribs 9, thereby effectively blocking the wind field between the wind wheel 4 and the chassis 111, optimizing the wind field backflow, reducing the noise of the whole machine, increasing the air volume of the whole machine, and enhancing the competitiveness of the ceiling machine 100 product.

[0138] In some embodiments of the present application, the width of the outer annular rib 9 is a. 15mm≤a. a≤20mm.

[0139] If the width of the outer annular rib 9 is too large, the arrangement of other annular ribs will be limited. In order to set at least two annular ribs, the width of the outer annular rib is set to be no greater than the fifth parameter value. For example, the fifth parameter value can be 20 mm, 19.5 mm, or 19 mm. Consider selecting a suitable and specific parameter in the specific design.

[0140] If the width of the outer annular rib 9 is too small, the wall attachment effect of the airflow will be reduced, more airflow will pass between the wind wheel and the chassis, and the airflow blocking effect will be reduced, which is not conducive to preventing backflow. In order to improve the airflow blocking effect, the width of the outer annular rib is set to be not less than the sixth parameter value. For example, the sixth parameter value can be 15mm, 15.5mm, or 16mm. Consider selecting a suitable and specific parameter in the specific design.

[0141] In some embodiments of the present application, the width a of the outer annular rib 9 is any value between 15 mm and 20 mm.

[0142] By setting the width of the outer annular rib 9 within a reasonable size range, the wall attachment effect of the airflow can be utilized to allow more airflow to flow along the outer annular rib, thereby improving the airflow blocking effect.

[0143] In some embodiments of the present application, the width of the other annular ribs 9 is b.5 mm ≤ b.b.10 mm.

[0144] If the width of other annular ribs 9 is too small, the airflow attachment effect will not be achieved, resulting in the airflow not flowing along the chassis. In order to achieve the airflow attachment effect, the width of other annular ribs 9 is set to be not less than the seventh parameter value. For example, the seventh parameter value can be 5mm, 5.5mm. Consider selecting a suitable and specific parameter in the specific design.

[0145] The width of other annular ribs 9 is too large, so that the wall attachment effect of the airflow is too good, resulting in failure to block the airflow. In order to improve the airflow blocking effect, the width of other annular ribs is set to be no greater than the eighth parameter value. For example, the eighth parameter value can be 10mm, 9.5mm. Consider selecting a suitable and specific parameter in the specific design.

[0146] The width of the other annular ribs 9 is set within the above reasonable range, which improves the airflow blocking effect, effectively blocks the wind field between the wind wheel and the chassis, prevents backflow, and facilitates the molding of the other annular ribs 9.

[0147] In some embodiments of the present application, when the number of the annular ribs 9 is set to be greater than or equal to three, the widths of the other annular ribs 9 may be equal.

[0148] The widths of the other annular ribs 9 are set to the same size to facilitate the processing of the rectifier plate 8 .

[0149] Of course, in some other embodiments, when the number of the annular ribs 9 is set to be greater than or equal to three, the widths of the other annular ribs 9 may be unequal.

[0150] In some embodiments of the present application, there is a gap between two adjacent annular ribs 9, and when there are at least two gaps, the size of the outer gap of the at least two gaps is larger than the size of the other gaps of the at least two gaps. The outer gap is farther away from the central axis of the indoor fan than the other gaps.

[0151] By setting the size of the outer interval to be larger than that of other intervals, it can be effectively ensured that the airflow flowing through the outer annular rib wall attachment effect has a suitable buffer area, forming a small reflux locally, thereby reducing the airflow from continuing to flow inward and improving the airflow blocking effect.

[0152] According to an embodiment of the present disclosure, the size of the outer spacing is d. 15mm≤d. d≤20mm.

[0153] If the outer spacing is too large, the airflow will flow back along the bottom surface of the wind wheel 4 to the negative pressure area side of the motor 3, and it will not play a blocking role. In order to effectively play a blocking role, the outer spacing is set to be no greater than the ninth parameter value. For example, the ninth parameter value can be 20mm, 19.5mm, or 19mm. Consider selecting a suitable and specific parameter in the specific design.

[0154] The outer spacing is too small to reserve enough buffer area for the airflow. The airflow from the wall effect does not pass through the outer spacing and flows directly to the next annular rib, which is not conducive to noise reduction. In order to provide a buffer area for the airflow from the wall effect, the outer spacing is set to be no less than the tenth parameter value. For example, the tenth parameter value can be 15mm, 15.5mm, or 16mm. Consider selecting a suitable specific parameter in the specific design.

[0155] Setting the size of the outer partition within a reasonable range can not only play a blocking role but also buffer the airflow, which is conducive to optimizing the airflow in the wind field.

[0156] According to an embodiment of the present disclosure, the size of the other intervals is e. 10 mm ≤ e. e. ≤ 15 mm.

[0157] If other intervals are too large, the outer intervals will be too large, and the position of each annular rib 9 cannot be guaranteed, and then all the annular ribs cannot be within the projection of the wind wheel to the chassis, and the wind field return flow cannot be optimized. In order to ensure the position of each annular rib 9, the other intervals are set to be no greater than the eleventh parameter value. For example, the eleventh parameter value can be 15mm, 14.5mm, or 14mm. Consider selecting a suitable and specific parameter in the specific design.

[0158] The other intervals are too small, so that the other intervals cannot buffer the airflow from the wall effect, and the airflow continues to flow inward. In order to effectively buffer the airflow from the wall effect, the other intervals are set to be no less than the twelfth parameter value. For example, the twelfth parameter value can be 10mm, 10.5mm, 11mm. Consider selecting a suitable and specific parameter in the specific design.

[0159] Setting the sizes of other intervals within a reasonable range can ensure the position of each annular rib and buffer the airflow coming from the buffer wall effect, thereby making the wind field in the air duct smoother, reducing noise values ​​and increasing air volume.

[0160] In some other embodiments of the present application, the cross section of the annular rib 9 is substantially trapezoidal. The side of the annular rib 9 away from the rectifier plate 8 and the side connected to the rectifier plate 8 are transitioned through a rounded corner.

[0161] The ring and the rectifying plate 8 are connected and transitioned by fillets. The connection and transition by fillets is conducive to the flow of air.

[0162] refer to Fig.18 It can be understood that, in this embodiment, the width of the annular rib is the width of the straight line segment of the annular rib without rounded corners. The width of the interval is the width of the straight line segment of the interval without rounded corners.

[0163] The ceiling fan 100 provided in the above embodiment is subjected to noise comparison test with the ceiling fan without the rectifier plate 8 in the prior art, and the test environment and test position are the same during the test. Table 1 and Table 2 respectively show the noise and air volume comparison data before and after adding the rectifier plate 8.

[0168]

[0169] From the data in Table 1 and Table 2, it can be seen that the ceiling fan 100 provided in this embodiment has significantly reduced noise after adding the rectifier plate 8, and at the same speed, the noise is reduced by an average of 1.5 dB. At the same time, the air volume of the whole machine is improved to a certain extent.
