[0002] At present, the air outlet assembly of the ceiling machine in the prior art forms an air outlet with the main frame arranged on the outside of the air outlet assembly. The fan blows air from the inside of the ceiling machine through the air outlet, and uses the air guide plate at the air outlet to guide the airflow. Especially when the air conditioner is in cooling mode, it is necessary to make the air outlet as parallel to the horizontal plane as possible to increase the air supply distance, thereby achieving waterfall-style cooling and improving user comfort. However, the air guide plates of the ceiling machine in the prior art are designed to adjust the air outlet direction of the ceiling machine based solely on the angle of the air guide plate, without considering the influence of the internal structure of the ceiling machine on the air outlet direction of the ceiling machine, which ultimately causes the problem of poor air outlet effect of the ceiling machine. Summary of the Invention

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] In the prior art, there is the following relationship between the air supply distance and the air volume of the ceiling machine: when the air supply distance is long, the air volume attenuation is large, while when the air supply distance is short, the air volume attenuation is small. In addition, due to the structural limitations of the ceiling machine, the structure of the internal air duct of the ceiling machine is generally fixed, so all ceiling machines use the method of setting an air guide plate at the first air outlet to adjust the air outlet direction of the ceiling machine to achieve the purpose of improving the air outlet effect of the ceiling machine. However, after the applicant studied the air flow of the ceiling machine and analyzed the experimental data through simulation, it was found that setting an air guide plate at the first air outlet alone actually has little effect on the air outlet effect of the ceiling machine, and the air outlet direction of the air duct, which has been ignored and neglected in this field, is actually an improvement point that can effectively improve the heating efficiency of the ceiling machine.

[0038] Therefore, this application provides Figure 1 and Figure 2 The illustrated overhead crane with a second air guide plate includes: a main frame 1, within which is disposed an air outlet duct 2 having a first end 21 and a second end 22 along the airflow direction; an air outlet assembly 3, with a first air outlet 10 formed between the air outlet assembly 3 and the main frame 1, the first air outlet 10 communicating with the second end 22 of the air outlet duct 2; a second air guide plate 6, which is swingably disposed within the air outlet duct 2 and can change the air outlet direction of the air outlet duct 2; and a first air guide plate 4, which is swingably disposed on the air outlet assembly 3. The cooperation of the first air guide plate 4 and the second air guide plate 6 further enhances the adjustment of the air outlet direction of the overhead crane, ultimately ensuring the air outlet effect of the overhead crane.

[0039] The angle c is formed between the plane where the first air guide plate 4 is located and the plane where the second air guide plate 6 is located. The second air guide plate 6 is provided to guide the direction of the airflow in the air outlet duct. For example, when the air outlet volume of the ceiling machine is large, the obstruction caused by the ceiling machine structure between the second end of the air outlet duct and the first air outlet is not obvious, and the air outlet direction at the first air outlet can meet the preset requirements. Therefore, the second air guide plate 6 at this time does not need to guide the airflow in the air outlet duct 2, that is, the second air guide plate 6 is parallel to the airflow direction in the air outlet duct 2. However, when the air outlet volume is small, the ceiling machine structure between the second end of the air outlet duct and the first air outlet will seriously hinder the gas circulation inside the ceiling machine and even cause turbulence, making the air outlet direction of the first air outlet 10 change uncontrollably. At this time, the second air guide plate 6 is adjusted to adjust the airflow direction in the air outlet duct 2 using the second air guide plate 6. The air outlet direction of the air outlet duct is closer to the air outlet direction required by the first air outlet 10, and the obstruction of the ceiling machine structure between the second end of the air outlet duct and the first air outlet is reduced as much as possible to ensure the air outlet effect of the ceiling machine. At the same time, by limiting the angle c, a standard is provided for designers to facilitate the determination of the parameters of the second air guide plate 6. For example, the width of the second air guide plate 6 can be determined according to the maximum value of the angle c and the width of the corresponding position of the air outlet duct, so as to avoid the problem that the second air guide plate 6 interferes with the inner surface of the air outlet duct when it swings to the angle c. Among them, the maximum value of the angle c is inversely proportional to the width of the second air guide plate 6. The larger the maximum value of the angle c, the smaller the width value of the second air guide plate 6, and the smaller the maximum value of the angle c, the larger the width value of the second air guide plate 6, thereby ensuring that the air outlet effect of the ceiling machine product meets the preset requirements.

[0040] The outlet direction of the air outlet duct 2 is the direction of airflow passing through the second end 22 of the air outlet duct 2, and the outlet direction of the first air outlet is the direction of airflow passing through the first air outlet. The height of the first air outlet 10 is the height between the edge of the main frame 1 forming the lowest point of the air outlet duct 2 and the outermost edge of the first air guide plate 4 in the direction of the air outlet assembly 3.

[0041] It should be noted that the main frame 1 is the primary load-bearing structure of the ceiling unit. When the ceiling unit is installed, the main frame 1 is used to be mounted on the ceiling. Other structures can be directly or indirectly mounted on the main frame 1 and fixed to the ceiling through the main frame 1. The ceiling unit has an internal unit portion installed in the ceiling. The main frame 1 is connected to the internal unit. The air outlet assembly 3 is connected to the main frame 1. The internal unit has an internal unit exhaust port. The first end 21 of the outlet duct 2 of the main frame 1 is connected to the internal unit exhaust port. The air flow path is: return air port - evaporator - internal unit exhaust port - first end 21 of the outlet duct 2 - second end 22 of the outlet duct 2 - first outlet 10 for blowing out.

[0042] The skylight machine has a cooling mode. When the skylight machine is in the cooling mode, the angle c ranges from 90° to 110°.

[0043] Taking the overhead crane of this application as an example, under the condition that the width of the second air guide plate is 30 mm, the simulation is performed by adjusting the angle c. The simulation results are as follows:

[0044] Angle c Air volume Air supply distance 80° 1000 2.9m 90° 1089 3.4m 100° 1112 3.5m 110° 1055 3.4m 120° 990 2.6m

[0045] The simulation results show that when the overhead unit is in cooling mode, when the angle c is 100°, the air volume and air supply distance both reach their maximum values. When the angle c increases to 110°, the air volume and air supply distance both begin to decrease. When the angle c continues to increase to 120°, the air volume and air supply distance both severely decrease, failing to meet the requirements of the overhead unit. When the angle c decreases to 90°, the air volume and air supply distance both begin to decrease, and when the angle c continues to decrease to 80°, the air volume and air supply distance also experience severe attenuation, failing to meet the requirements of the overhead unit. In other words, when the overhead unit is in cooling mode, only when the angle c is within the range of 90° to 110° can the air volume and air supply distance be reasonably matched to meet the air outlet requirements of the overhead unit.

[0046] The skylight machine has a heating mode. When the skylight machine is in the heating mode, the angle c ranges from 145° to 165°.

[0047] Taking the overhead crane of this application as an example, under the condition that the width of the second air guide plate is 30 mm, the simulation is performed by adjusting the angle c. The simulation results are as follows:

[0048] Angle c Air volume Air supply distance 135° 1005 0.5m 145° 1089 0.8m 155° 1112 1.0m 165° 1112 1.2m 175° 1000 1.5m

[0049] From the simulation results, we can see that when the ceiling unit is in heating mode, when the angle c is 155°, the air volume reaches the maximum value. Although the air supply distance does not reach the minimum value, this air supply distance can make the air output of the ceiling unit basically blow vertically downward, thereby achieving the purpose of rapid heating; when the angle c increases to 165°, although the air volume remains unchanged, the air supply distance begins to increase, indicating that the efficiency of the air output of the ceiling unit flowing to the ground is reduced at this time; when the angle c continues to increase to 175°, the air volume is seriously attenuated, and the air supply distance is seriously increased, and there is no It cannot meet the requirements of the ceiling unit; when the angle c decreases to 145°, the air volume begins to decrease, and the air supply distance also begins to decrease. However, since the first air outlet of the ceiling unit surrounds the return air outlet, when the air supply distance decreases, it can be seen that part of the airflow from the first air outlet may be sucked into the return air outlet; when the angle c continues to decrease to 135°, the air volume and air supply distance will also be severely attenuated. The air supply distance at this time indicates that the air outlet of the ceiling unit must be sucked into the return air outlet, and the air outlet effect of the ceiling unit can no longer be guaranteed. That is, when the ceiling unit is in heating mode, only when the angle c is within the range of 145° to 165° can the air volume and air supply distance be reasonably matched to meet the air outlet requirements of the ceiling unit.

[0050] The air outlet assembly has a closed position that cooperates with the main frame 1 to close the first air outlet 10. The first air guide plate 4 has a first edge 41 and a second edge 42. When the air outlet assembly 3 is in the closed position, the first edge 41 is sealed against the corresponding position of the main frame 1, and the second edge 42 is sealed against the corresponding edge of the air outlet assembly 3. The corresponding sealing between the first edge 41 and the main frame 1 and the corresponding sealing between the second edge 42 and the air outlet assembly ensures that when the air outlet assembly is in the closed position, the first air guide plate 4 can seal the corresponding position of the first air outlet 10, thereby preventing dust and other impurities from entering the interior of the overhead crane through the first air outlet 10 and affecting the performance of the overhead crane.

[0051] When the air outlet assembly 3 is in the closed position, the air outlet assembly 3 and the first air guide plate 4 cooperate with the main frame 1 to form a seal.

[0052] A first step structure is provided on the second edge 42, and a second step structure is provided on the air outlet assembly 3 to cooperate with the first step structure. When the air outlet assembly 3 is in the closed position, the first step structure and the second step structure cooperate in a sealing manner. The first and second step structures ensure a reliable seal between the first air guide plate 4 and the air outlet assembly 3, while also ensuring that during the swinging of the first air guide plate 4, there is no structural interference with the air outlet assembly 3, which would affect the structural reliability of the air outlet assembly 3.

[0053] A seal is provided on the first step structure, and when the air outlet assembly 3 is in the closed position, the seal is disposed between the first step structure and the second step structure. In other words, the seal moves along with the air guide plate. When the air guide plate and the air outlet assembly are relatively sealed, the seal can close the gap between the air guide plate and the air outlet assembly, thereby enhancing the sealing effect between the air guide plate and the air outlet assembly.

[0054] The skylight crane further includes a swing mechanism, which is arranged on the air outlet assembly 3, and the first air guide plate 4 is arranged on the swing mechanism.

[0055] The swing mechanism includes a rotating arm 5, one end of which is hinged to the air outlet assembly 3, and the other end of which is provided on the first air guide plate 4. Preferably, a rotating arm 5 is provided at both ends of the first air guide plate 4 in the longitudinal direction to ensure the synchronization of the overall movement of the first air guide plate 4.

[0056] The swing mechanism also includes a driver, which is mounted on the air outlet assembly 3 and directly or indirectly drives the rotating arm 5 to rotate. One end of the rotating arm 5 is mounted on the driver, and the first air deflector 4 is mounted on the other end of the rotating arm 5. When the rotating arm 5 rotates with the end mounted on the driver, the first air deflector 4 can move along with the end of the rotating arm 5, thereby achieving the swing of the first air deflector 4. The driver can be a stepping motor.

[0057] The second air guide plate 6 divides the air outlet duct 2 into a first air outlet duct and a second air outlet duct.

[0058] Along the airflow direction of the air outlet duct 2 , the width of the first air outlet duct gradually decreases; and / or, along the airflow direction of the air outlet duct 2 , the width of the second air outlet duct gradually decreases.

[0059] The overhead hood has a cooling mode. When the overhead hood is in the cooling mode, the ratio of the average width D1 of the first air outlet duct to the average width D2 of the second air outlet duct is in the range of 1.0≤D1 / D2≤1.1.

[0060] Taking the overhead crane of this application as an example, under the condition that the width of the second air guide plate is 30 mm, simulation is performed by adjusting the ratio of D1 / D2 and the angle c. The simulation results are as follows:

[0061] Angle c D1 / D2 Air volume Air supply distance 80° 1.1 1000 2.9m 90° 1.1 1089 3.4m 100° 1.1 1112 3.5m 110° 1.0 1055 3.4m 120° 1.0 990 2.6m

[0062] From the simulation results, it can be seen that when the overhead unit is in cooling mode, under the condition that D1 / D2 is 1.1, when the angle c is 100°, the air volume and air supply distance both reach their maximum value; when the angle c decreases to 90°, the air volume and air supply distance both begin to decrease, and when the angle c continues to decrease to 80°, the air volume and air supply distance will also be severely attenuated, which cannot meet the requirements of the overhead unit; under the condition that D1 / D2 is 1.0, when the angle c increases to 110°, the air volume and air supply distance both begin to decrease; when the angle c continues to increase to 120°, the air volume and air supply distance both are severely attenuated, which cannot meet the requirements of the overhead unit. That is, when the overhead unit is in cooling mode, under the condition that D1 / D2 is 1.1, the angle c is within the range of 90° to 100°, so that the air volume and air supply distance are reasonably matched to meet the air outlet requirements of the overhead unit; under the condition that D1 / D2 is 1.0, the angle c is within the range of 100° to 110°, so that the air volume and air supply distance are reasonably matched to meet the air outlet requirements of the overhead unit.

[0063] The overhead unit has a heating mode. When the overhead unit is in the heating mode, a ratio of an average width D1 of the first air outlet duct to an average width D2 of the second air outlet duct is in a range of 1.2≤D1 / D2≤1.25.

[0064] Taking the overhead crane of this application as an example, under the condition that the width of the second air guide plate is 30 mm, simulation is performed by adjusting the ratio of D1 / D2 and the angle c. The simulation results are as follows:

[0065] Angle c D1 / D2 Air volume Air supply distance 135° 1.25 1005 0.5m 145° 1.2 1089 0.8m 155° 1.2 1112 1.0m 165° 1.2 1112 1.2m 175° 1.25 1000 1.5m

[0066] From the simulation results, it can be seen that when the overhead unit is in heating mode, under the condition that D1 / D2 is 1.2, when the angle c is 155°, the air volume and air supply distance both reach their maximum value; when the angle c decreases to 145°, the air volume and air supply distance both begin to decrease. When the angle c increases to 165°, although the air volume remains unchanged, the air supply distance begins to increase, which still makes the heating effect of the overhead unit worse; under the condition that D1 / D2 is 1.25, when the angle c continues to decrease to 135°, the air volume and air supply distance will also be severely attenuated, which cannot meet the requirements of the overhead unit; when the angle c continues to increase to 175°, the air volume is severely attenuated and the air supply distance is too large to meet the requirements of the overhead unit. That is, when the ceiling unit is in heating mode, only when the angle c is within the range of 145° to 165° under the condition that D1 / D2 is 1.2 can the air volume and air supply distance be reasonably matched to meet the air outlet requirements of the ceiling unit; when D1 / D2 is 1.25, when the angle c is less than 145° or greater than 165°, the air outlet requirements of the ceiling unit cannot be met.

[0067] The overhead crane has a cooling mode. When the overhead crane is in the cooling mode, the angle between the second air guide plate and the vertical plane ranges from 0° to 20°.

[0068] Taking the overhead crane of the present application as an example, under the condition that the width of the second air guide plate is 30 mm and the angle between the first air guide plate and the vertical plane is 90°, the angle c is changed by adjusting the angle between the second air guide plate and the vertical plane. The simulation results are as follows:

[0069] Angle c Angle between the second air guide plate and the vertical plane Air volume Air supply distance 80° -10° 1000 2.9m 90° 0° 1089 3.4m 100° 10° 1112 3.5m 110° 20° 1055 3.4m 120° 30° 990 2.6m

[0070] The simulation results show that when the overhead unit is in cooling mode, when the angle c is 100°, the air volume and air supply distance both reach their maximum values. When the angle c increases to 110°, the air volume and air supply distance both begin to decrease. When the angle c continues to increase to 120°, the air volume and air supply distance both severely decrease, failing to meet the requirements of the overhead unit. When the angle c decreases to 90°, the air volume and air supply distance both begin to decrease. When the angle c continues to decrease to 80°, the air volume and air supply distance also severely decrease, failing to meet the requirements of the overhead unit. In other words, when the overhead unit is in cooling mode, only when the angle c is within the range of 90° to 110°, that is, when the angle between the second air guide plate and the vertical plane is between 0° and 20°, can the air volume and air supply distance be reasonably matched to meet the air outlet requirements of the overhead unit.

[0071] The skylight unit has a heating mode. When the skylight unit is in the heating mode, the angle between the second air guide plate and the vertical plane ranges from -10° to 10°.

[0072] Taking the overhead crane of the present application as an example, under the condition that the width of the second air guide plate is 30 mm and the angle between the first air guide plate and the vertical plane is 90°, the angle c is changed by adjusting the angle between the second air guide plate and the vertical plane. The simulation results are as follows:

[0073] Angle c Angle between the second air guide plate and the vertical plane Air volume Air supply distance 135° -10° 1005 0.5m 145° 0° 1089 0.8m 155° 10° 1112 1.0m 165° 20° 1112 1.2m 175° 30° 1000 1.5m

[0074] From the simulation results, we can see that when the ceiling unit is in heating mode, when the angle c is 155°, the air volume reaches the maximum value. Although the air supply distance does not reach the minimum value, this air supply distance can make the air output of the ceiling unit basically blow vertically downward, thereby achieving the purpose of rapid heating; when the angle c increases to 165°, although the air volume remains unchanged, the air supply distance begins to increase, indicating that the efficiency of the air output of the ceiling unit flowing to the ground is reduced at this time; when the angle c continues to increase to 175°, the air volume is seriously attenuated, and the air supply distance is seriously increased, and there is no It cannot meet the requirements of the ceiling machine; when the angle c is reduced to 145°, the air volume begins to decrease, and the air supply distance also begins to decrease. However, since the first air outlet of the ceiling machine surrounds the return air outlet, when the air supply distance decreases, it can be seen that part of the airflow from the first air outlet may be sucked into the return air outlet; when the angle c continues to decrease to 135°, the air volume and air supply distance will also be severely attenuated. The air supply distance at this time indicates that the air outlet of the ceiling machine must be sucked into the return air outlet, and the air outlet effect of the ceiling machine can no longer be guaranteed. When the ceiling machine is in heating mode, when the angle c is within the range of 145° to 165°, that is, when the angle between the second air guide plate and the vertical plane is within the range of -10° to 10°, it can ensure that the air volume and air supply distance are reasonably matched to meet the air outlet requirements of the ceiling machine.

[0075] The air outlet assembly 3 is liftably disposed on the main frame 1 , and the air outlet assembly 3 can be lowered to form the first air outlet 10 with the main frame 1 .

[0076] The skylight machine further comprises a lifting mechanism, which is arranged on the main frame 1, and the air outlet assembly 3 is arranged on the lifting mechanism. The air outlet assembly 3 can be extended or retracted into the main frame 1 through the lifting mechanism.

[0077] The air outlet assembly 3 includes an air outlet frame, a first air outlet is formed between the air outlet frame and the main frame, and the air outlet frame is raised and lowered independently. In other embodiments not shown, the air outlet assembly 3 includes an air outlet frame and a return air panel, a first air outlet is formed between the air outlet frame and the main frame, and a return air panel is provided with a return air outlet. The air outlet frame and the return air panel are connected and raised and lowered together.

[0078] Preferably, the first air guide plate 4 can adjust the height of the first air outlet 10. At this time, the edge of the first air guide plate 4 away from the main frame 1 constitutes the edge of the air outlet assembly 3, so when the first air guide plate 4 swings, the height of the first air outlet 10 can change accordingly.

[0079] like Figure 3 and Figure 4The figure shows another embodiment of a ceiling fan. The air outlet assembly 3 is provided with at least one second air outlet 13, which communicates with the second end 22 of the air outlet duct 2. The provision of the second air outlet 13 enables the ceiling fan to meet the requirements of diagonally downward airflow, or even vertically downward airflow. Furthermore, the combination of the first air outlet 10 and the second air outlet 13 increases the number of air outlet options for the ceiling fan, thereby improving the fan's airflow efficiency, temperature regulation accuracy, and speed.

[0080] When the air outlet assembly 3 descends to form the first air outlet 10 between the air outlet assembly 3 and the main frame 1, a distance is formed between the air outlet assembly 3 and the main frame 1, and the distance forms an air supply duct 14. One end of the air supply duct 14 is connected to the second end 22 of the air outlet duct 2, and the other end of the air supply duct 14 forms the first air outlet 10. The airflow in the air outlet duct 2 is guided by the air supply duct 14 and then blown out from the first air outlet 10. The air supply duct 14 is used to guide the vertical downward airflow in the air outlet duct 2 to be discharged in a generally horizontal direction away from the overhead crane, or even in a direction inclined upward relative to the horizontal plane, thereby achieving horizontal air discharge to the overhead crane.

[0081] In the prior art, all ceiling machines use air outlets opened on the surface facing the ground to discharge air. In order to change the direction of the air outlet, an air guide plate is set at the air outlet to guide the air flow. However, on the installation plane of the ceiling machine, the projection of the air guide plate does not overlap with the projection of the panel of the ceiling machine, so that the air guide plate has a poor effect of guiding the air flow, which ultimately reduces the air supply distance of the ceiling machine. For this reason, the main frame 1 of the present application also includes a frame 15. When the air outlet component 3 is lowered to form the first air outlet 10 between the main frame 1, the air supply duct 14 is formed between the air outlet component 3 and the frame 15. On the installation plane of the main frame 1 (such as the ceiling), the projection of the air outlet component 3 and the projection of the frame 15 at least partially overlap. When the projection of the air outlet component 3 partially coincides with the projection of the frame 15, the air outlet component is substantially extended compared to the prior art, so that the horizontal blowing effect of the ceiling machine is good and the air supply distance is increased. When the ceiling machine opens the first air outlet 10, the air outlet component 3 gradually moves away from the main frame 1 to form the air supply duct 14. At this time, the corresponding part of the air outlet component 3 forms the lower side of the air supply duct 14. When the air flow passes through the air supply duct 14, the air flow flows in a horizontal direction or even blows out in an upward inclined direction under the guiding action of the lower side of the air supply duct, so that the air supply distance of the ceiling machine is increased, thereby achieving the effect of horizontal air outlet.

[0082] As another embodiment, the projection of the air outlet assembly 3 completely overlaps with the projection of the frame 15. In this case, compared to the case where the projection of the air outlet assembly 3 partially overlaps with the projection of the frame 15, the air outlet assembly can be further extended, thereby achieving a better flat blowing effect of the overhead crane and further increasing the air supply distance. At the same time, when the overhead crane is in the stopped state, the air outlet assembly 3 is attached to the main frame 1, and the corresponding part of the air outlet assembly 3 is attached to the frame 15. When a person observes the overhead crane from the ground, he can only see the air outlet assembly 3 and cannot see the main frame 1, which effectively increases the aesthetics of the overhead crane.

[0083] As another embodiment, the projection of the air outlet component 3 exceeds the projection of the frame 15. In this case, compared with the case where the projection of the air outlet component 3 completely coincides with the projection of the frame 15, the air outlet component can be further extended, thereby further increasing the flat blowing effect and air supply distance of the ceiling machine.

[0084] Preferably, the projection of the air outlet assembly 3 exceeds the projection of the main frame 1, so that the air outlet assembly 3 effectively increases the air guide size compared with the prior art, thereby achieving the purpose of increasing the air supply distance of the ceiling machine.

[0085] The first air guide plate 4 is rotatably disposed at the second air outlet 13, and the first air guide plate 4 can close or open the second air outlet 13. When the second air outlet 13 needs to be opened, the first air guide plate 4 gradually rotates to connect the second air outlet 13 with the air outlet duct 2, so that the airflow in the air outlet duct 2 can be blown out through the second air outlet 13, and the first air guide plate 4 can adjust its inclination angle according to actual needs to adjust the air outlet direction and / or air volume of the second air outlet 13; and when the second air outlet 13 needs to be closed, the first air guide plate 4 is reset to a state of sealing cooperation with the air outlet assembly 3, thereby closing the second air outlet 13. At this time, the airflow in the air outlet duct 2 can only be blown out through the first air outlet 10 under the joint guidance of the air outlet assembly 3 and the first air guide plate 4.

[0086] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
