Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent fan lamps, and in particular to an intelligent high-power multi-layer invisible fan lamp based on data points. BACKGROUND

[0002] Fan lamps, as integrated home products combining lighting and air circulation functions, have attracted widespread attention in recent years. Traditional fan lamps usually adopt a boom structure, which not only affects the overall aesthetics of the lamp, but also has potential safety hazards due to its downward extension. In addition, the limited installation space severely restricts the size and power of the drive motor, resulting in insufficient fan airflow and low motor heat dissipation efficiency. Long-term high-load operation can easily shorten the service life and even cause failure due to overheating.

[0003] In addition, the fan system of existing products generally has low intelligence, and its working mode is mostly simple start-stop control, which cannot perceive complex actual use environments. When there is reverse airflow from doors and windows or air conditioners indoors, the aerodynamic load of the fan blades will change dramatically, causing the motor torque to fluctuate, producing unpleasant noise and vibration, and forcing the motor to frequently output peak torque to maintain speed, resulting in increased energy consumption and accelerated temperature rise. Current products on the market lack intelligent identification and adaptive adjustment capabilities for such dynamic operating conditions.

[0004] Therefore, there is an urgent need for an innovative design scheme to fundamentally solve the limitations of structure and performance, and to develop a multi-layer invisible fan lamp that has high power output, efficient heat dissipation, aesthetics and safety, and can intelligently perceive the environment and adaptively adjust to ensure smooth and quiet operation.

[0005] Chinese Patent Publication No. CN119825727A discloses an invisible fan lamp, comprising: a mounting base, a motor with a hollow shaft is coaxially arranged with the mounting base, and the mounting base rotates with the motor; a mounting fixed seat is arranged above the mounting base, one end of the mounting fixed seat is connected with the ceiling, and the other end is connected with the hollow shaft; a fan blade is arranged in a circumferential array and is pivotally connected to the inner side of the edge of the mounting base. When the mounting base rotates, the fan blade unfolds in a direction away from the mounting base. When the mounting base stops rotating, the fan blade folds towards the mounting base; and a mounting base plate is arranged below the mounting base, one end of the mounting base plate is connected with the hollow shaft, and the other end is connected with a light emitting element. In the fan lamp, the motor is not exposed along the direction of the rotating shaft of the motor and perpendicular to the rotating shaft, and the outer side of the motor is provided with a heat dissipation structure. This design has the advantages of low noise, aesthetics, and good heat dissipation.

[0006] Therefore, the invisible fan lamp still has the problems of affecting the appearance of the fan lamp and occupying a large indoor space due to the design of the boom, and the motor power fluctuation is large when the invisible fan lamp cannot timely and intelligently respond to the change of the gas flow characteristics, and the motor cannot be kept running at high power for a long time. SUMMARY

[0012] Further, the air flow judgment module determines that a direction of air flow in the indoor environment is opposite to a rotating direction of the plurality of fan blades according to that the air resistance torque variation trend of the first driving motor is an upward trend.

[0013] Further, the state monitoring module determines that a working parameter of the plurality of fan blades is unqualified and acquires an initial inclination angle of the plurality of fan blades according to that a total number of peak torques of the first driving motor is greater than or equal to a preset total number under a condition that the direction of air flow in the indoor environment is opposite to the rotating direction of the plurality of fan blades. wherein the initial inclination angle is an inclination angle of the plurality of fan blades relative to a rotating plane under a condition that the plurality of fan blades cope with the opposite air flow state, and the initial inclination angle is 20°.

[0014] Further, the parameter adjustment module determines to decrease the initial inclination angle of the plurality of fan blades according to that a torque fluctuation coefficient of the first driving motor under the condition that the first driving motor overcomes the opposite air flow state is less than a preset torque fluctuation coefficient.

[0015] Further, the parameter adjustment module determines to decrease the initial inclination angle of the plurality of fan blades according to that a torque fluctuation coefficient of the first driving motor under the condition that the first driving motor overcomes the opposite air flow state is greater than or equal to a preset torque fluctuation coefficient.

[0016] Further, the vibration monitoring module determines that an adjustment manner of adjusting the inclination angle of the plurality of fan blades is unqualified according to that an average deviation value of the vibration amplitude of the plurality of fan blades after the adjustment is greater than or equal to a preset average deviation value.

[0017] Further, the optimization module determines to keep an original adjustment direction and decrease a step length of single adjustment according to that a difference between the average deviation value of the vibration amplitude of the plurality of fan blades and the preset average deviation value is less than a preset difference value.

[0020] Further, the mode determination module automatically controls the opening working mode of the invisible fan layer when the indoor environment temperature value monitored by the temperature sensor in real time is greater than the preset temperature value, for indoor cooling, and the fan stops working when the indoor temperature is lower than the preset temperature value, so that intelligent temperature regulation is realized, unnecessary energy waste is avoided, good energy-saving effect is achieved, the service life of the driving motor is prevented from being reduced due to the forgetting of the closing of the fan and the long-time working of the driving motor, and the later maintenance cost of the driving motor is reduced.

[0021] Further, the air flow judgment module judges the direction of the air flow in the indoor environment relative to the rotation direction of the plurality of fan blades by using the change trend of the air resistance torque of the fan when the fan is working, when the air resistance torque appears an upward trend, it is judged that the direction of the air flow in the indoor environment is opposite to the rotation direction of the plurality of fan blades, so that the equipment can timely find the gas flow characteristics in the environment where the fan is currently working.

[0022] Further, the state monitoring module judges whether the working parameters of the plurality of fan blades are qualified by the number of peak torques of the first driving motor when the air flow direction is opposite to the plurality of fan blades, so that the unqualified inclination angle of the plurality of fan blades when coping with the reverse air flow can be timely found, and mechanical damage caused by the long-time driving of the first driving motor to the plurality of fan blades under the condition of large air resistance can be avoided.

[0032] In the embodiment of the present application, the installation part includes but is not limited to a ceiling and a hollow wall, and is specifically determined according to the actual installation environment, which is not limited here.

[0034] In the embodiment of the present application, the first driving motor 4 is connected with the plurality of second driving motors 5 and the plurality of third driving motors 6 through conductive slip rings.

[0035] The monitoring device comprises a temperature sensor 10 fixedly arranged on the upper part of the first layer structure for monitoring the temperature change of the indoor environment in real time, a current sensor 12 for monitoring the current value input into the first driving motor in the current state in real time, and a plurality of displacement sensors 11 fixedly arranged at the roots of the plurality of fan blades; The cooperative control unit is connected with the monitoring device and comprises: The data acquisition module is connected with the monitoring device, and is used to acquire the temperature change parameter of the indoor environment monitored by the temperature sensor, the temperature change parameter of the first driving motor in the current working state, and the current parameter input into the first driving motor in the current working state; The mode determination module is connected with the data acquisition module, and is used to determine whether the invisible fan layer executes the working mode according to the temperature value of the indoor environment in the current state monitored by the temperature sensor; an air flow judgment module connected with the mode determination module, configured to determine the direction of the air flow in the indoor environment relative to the plurality of fan blades according to the torque change trend of the first driving motor; a state monitoring module connected with the air flow judgment module and the mode determination module respectively, configured to determine whether the working parameters of the plurality of fan blades are qualified according to the total number of peak torque values of the first driving motor under the condition that the direction of the air flow in the indoor environment is opposite to the plurality of fan blades; a parameter adjustment module connected with the state monitoring module, configured to adjust the initial inclination angle of the plurality of fan blades in response to the reverse air flow according to the torque fluctuation coefficient of the first driving motor under the condition that the working parameters of the plurality of fan blades are unqualified; a vibration monitoring module connected with the parameter adjustment module, configured to determine whether the adjustment mode of the inclination angle of the plurality of fan blades is qualified according to the vibration amplitude of the plurality of fan blades after the parameter adjustment module adjusts the working parameters of the plurality of fan blades in the invisible fan layer; an optimization module connected with the parameter adjustment module and the vibration monitoring module respectively, configured to optimize the adjustment mode according to the difference between the vibration amplitude of the plurality of fan blades and the preset vibration amplitude under the condition that the vibration monitoring module determines that the adjustment mode is unqualified. Specifically, by optimizing the structure of the fan lamp, canceling the traditional fan lamp's suspension rod design, adopting layered design, firmly installing the first layer structure on the surface of the ceiling, the stability of the fan lamp can be enhanced, the hidden danger that the safety is affected by the downward extension of the suspension rod is effectively solved, and the occupation of the indoor space is reduced. The layered design solves the problem of insufficient wind power caused by the fact that the traditional fan lamp cannot use a high-power driving motor due to the small space.

[0036] Please refer to Figure 5 as shown, Figure 5 which is a logic block diagram for determining whether the invisible fan layer executes the working mode according to the temperature value of the indoor environment.

[0037] Specifically, the data acquisition module acquires the temperature value of the indoor environment under the current environmental state monitored by the temperature sensor, and the mode determination module determines whether the invisible fan layer executes the working mode according to the comparison result of the temperature value under the current environmental state and the preset temperature value, wherein, if the temperature value is less than the preset temperature value, it is determined that the invisible fan layer does not execute the working mode; if the temperature value is greater than or equal to the preset temperature value, it is determined that the invisible fan layer executes the working mode; The preset temperature value is preferably 25 DEG C, and the preferred value range and preferred value of the preset temperature value can be determined according to actual conditions, which is not limited here.

[0038] In the embodiment of the application, the preset temperature value is 25 DEG C, and in the implementation, whether the invisible fan layer executes the working mode is determined according to the comparison result of the temperature value in the current environment and the preset temperature value, for example, in the case that the temperature value is 22 DEG C, the temperature value is less than the preset temperature value, which indicates that the temperature of the indoor environment is low, and additional air flow is not needed for cooling, at this time, it is determined that the invisible fan layer does not execute the working mode, for example, in the case that the temperature value is 28 DEG C, the temperature value is greater than the preset temperature value, which indicates that the temperature of the indoor environment is high, and additional air flow is needed for cooling the indoor environment, at this time, it is determined that the invisible fan layer executes the working mode.

[0039] When the mode determination module determines that the invisible fan layer starts to execute the working mode, the working mode is that the second driving motor provided at the connection between the first driving motor and the plurality of fan blades drives the plurality of fan blades to stretch along the shaft, so that the state of the plurality of fan blades changes from the converging state to the relaxed state, and the initial state of the plurality of fan blades is changed, and when the plurality of second driving motors drive the plurality of fan blades to the limiting groove, the operation is stopped, at this time, the plurality of fan blades are completely relaxed, and the first driving motor starts to rotate to provide rotating force for the plurality of fan blades, at this time, the rotating speed of the plurality of fan blades is increased to bring the effect of air flow to the indoor environment to reduce the temperature of the indoor environment.

[0040] Specifically, the mode determination module automatically controls the invisible fan layer to start the working mode for indoor cooling when the indoor environment temperature value monitored by the temperature sensor in real time is greater than the preset temperature value, and the fan stops working when the indoor temperature is lower than the preset temperature value, so that intelligent temperature regulation is realized, unnecessary energy waste is avoided, good energy-saving effect is achieved, the use life of the driving motor is prolonged, and the maintenance cost of the driving motor in the later period is reduced.

[0041] Please refer to Figure 6 as shown, Figure 6 The logic block diagram for determining the direction of air flow relative to the direction of rotation of the plurality of fan blades according to the air resistance torque change trend of the embodiment of the application.

[0042] Specifically, in the working process of the plurality of fan blades, the air flow determination module determines the direction of air flow in the indoor environment relative to the plurality of fan blades according to the air resistance torque change trend of the first driving motor, wherein, If the air resistance torque change trend is an upward trend, it is determined that the air flow in the indoor environment is opposite to the rotation direction of the plurality of fan blades. If the air resistance torque change trend is a downward trend, it is determined that the air flow in the indoor environment is in the same direction as the rotation direction of the plurality of fan blades. The air resistance torque is the torque consumed by the plurality of fan blades to overcome air resistance at a certain speed, and the value range of the certain speed is 1400-1600 RPM, and the preferred value of the application is 1500 RPM. The air resistance torque is obtained by calculating the difference between the total torque of the fan at a speed of 1500 RPM and the no-load torque of the fan without fan blades. In actual application, the current value input to the first driving motor of the fan at a speed of 1500 RPM is first obtained in real time by the current sensor, which is 2A. The torque constant of the first driving motor is obtained by the manufacturing specification parameters of the first driving motor, which is 0.2 N·m / A. The product of the current value and the torque constant is calculated to obtain the total torque, which is 0.4 N·m. The no-load current value flowing through the first driving motor of the fan at a speed of 1500 RPM in a no-load state is obtained by further testing, which is 0.5A. At this time, the product of the no-load current value and the torque constant is calculated to obtain the no-load torque, which is 0.1 N·m. Finally, the difference between the total torque and the no-load torque is calculated to obtain the air resistance torque, which is 0.3 N·m.

[0043] In the embodiment of the application, if the air resistance torque change trend at the same speed is an upward trend, that is, the value of the air resistance torque becomes larger, which indicates that the air flow in the indoor environment is not the same as the rotation direction of the plurality of fan blades. At this time, it is determined that the air flow in the indoor environment is opposite to the rotation direction of the plurality of fan blades.

[0044] Specifically, the air flow judgment module uses the air resistance torque change trend of the fan when working to determine the direction of the air flow in the indoor environment relative to the rotation direction of the plurality of fan blades. When the air resistance torque appears an upward trend, it is determined that the direction of the air flow in the indoor environment is opposite to the rotation direction of the plurality of fan blades, so that the device can timely discover the gas flow characteristics in the environment where the fan is currently working.

[0045] Please refer to Figure 7 as shown, Figure 7 The logic block diagram for determining whether the working parameters of the plurality of fan blades are qualified according to the total number of peak torque in the embodiment of the application.

[0046] Specifically, the air flow judgment module determines the air flow direction in the indoor environment, and if the air flow direction is opposite to the plurality of blades, the state monitoring module determines whether the working parameters of the plurality of blades are qualified according to a comparison result of the total number of peak torques of the first driving motor and a preset total number of peak torques, wherein, If the total number of peak torques is less than the preset total number of peak torques, it is determined that the working parameters of the plurality of blades are qualified. If the total number of peak torques is greater than or equal to the preset total number of peak torques, it is determined that the working parameters of the plurality of blades are unqualified, and an initial inclination angle of the plurality of blades is obtained. The preset total number of peak torques is preferably 3, and the preferred value range and preferred value of the preset total number can be determined according to actual conditions, which is not limited here.

[0047] The total number of peak torques is the number of maximum torques that the first driving motor can output when the plurality of blades are coping with the reverse air flow in the time period.

[0048] In the embodiment of the present application, the preset total number of peak torques is 2, and in the implementation, whether the working parameters of the plurality of blades are qualified is determined according to the comparison result of the total number of peak torques of the first driving motor and the preset total number of peak torques. For example, in the case where the total number of peak torques is 1, the total number of peak torques is less than the preset total number of peak torques, which indicates that the first driving motor only appears once the maximum torque that it can output to drive the plurality of blades to cope with the reverse air flow when the plurality of blades are coping with the reverse air flow, and at this time, it is determined that the working parameters of the plurality of blades are qualified. For example, in the case where the total number of peak torques is 5, the total number of peak torques is greater than the preset total number of peak torques, which indicates that the first driving motor appears multiple times the maximum torque that it can output to drive the plurality of blades to cope with the reverse air flow when the plurality of blades are coping with the reverse air flow, and at this time, it is determined that the working parameters of the plurality of blades are unqualified.

[0049] The initial inclination angle is the inclination angle of the plurality of blades relative to the rotation plane in the state of coping with the reverse air flow, and the value of the present application is 20°.

[0050] Specifically, the state monitoring module determines whether the working parameters of the plurality of blades are qualified by judging the number of peak torques of the first driving motor when the air flow direction is opposite to the plurality of blades, which can timely find that the inclination angle of the plurality of blades is unqualified when coping with the reverse air flow, and avoid mechanical damage caused by the first driving motor driving the plurality of blades for a long time under the condition of large air resistance.

[0051] Referring to Figure 8 as shown, Figure 8 is a logic block diagram for determining the adjustment mode according to the torque fluctuation coefficient in the embodiment of the present application.

[0052] Specifically, under the condition that the state monitoring module determines that the working parameters of the plurality of blades are unqualified, the parameter adjustment module determines to adjust the initial inclination angle of the plurality of blades when coping with the reverse airflow in the corresponding adjustment mode according to the comparison result of the torque fluctuation coefficient of the first driving motor in driving the plurality of blades to overcome the reverse airflow at the initial inclination angle of 20° and the preset torque fluctuation coefficient, wherein, if the torque fluctuation coefficient is less than the preset torque fluctuation coefficient, it is determined to adjust the inclination angle of the plurality of blades when coping with the reverse airflow in the first adjustment mode; if the torque fluctuation coefficient is greater than or equal to the preset torque fluctuation coefficient, it is determined to adjust the inclination angle of the plurality of blades when coping with the reverse airflow in the second adjustment mode; wherein the value range of the preset torque fluctuation coefficient is 0.3-0.5, the preferred value of the present application is 0.4, and the preferred value range and preferred value of the preset torque fluctuation coefficient can be determined according to the actual situation, which is not limited here.

[0053] wherein the torque fluctuation coefficient is obtained by the ratio of the difference between the maximum value and the minimum value of the torque and the average value of the torque within the time period of overcoming the reverse airflow of the plurality of blades driven by the first driving motor, in actual application, the time period of overcoming the reverse airflow is divided into a plurality of time periods, the torque data output by the first driving motor for driving the plurality of blades to overcome the reverse airflow within the plurality of time periods is obtained, the maximum torque value and the minimum torque value in the torque data are selected, the difference between the maximum torque value and the minimum torque value is calculated, then the average value of the torque data is calculated, finally the ratio of the difference value and the average value is calculated, and the torque fluctuation coefficient within the time period of overcoming the reverse airflow is obtained.

[0054] In an embodiment of the present invention, the preset torque fluctuation coefficient is set to 0.4. During implementation, based on the comparison result of the torque fluctuation coefficient of the first drive motor when driving the plurality of fan blades to overcome the reverse airflow and the preset torque fluctuation coefficient, it is determined that the inclination angles of the plurality of fan blades in response to the reverse airflow are adjusted in a corresponding adjustment manner. For example, when the torque fluctuation coefficient is set to 0.25, it is consistent with the fact that the torque fluctuation coefficient is less than the preset torque fluctuation coefficient, indicating that the fluctuation of the first drive motor in driving the plurality of fan blades to overcome the reverse airflow is small. At this time, it is determined that the inclination angles of the plurality of fan blades in response to the reverse airflow are adjusted in the first adjustment manner. For example, when the torque fluctuation coefficient is set to 0.6, it is consistent with the fact that the torque fluctuation coefficient is greater than the preset torque fluctuation coefficient, indicating that the fluctuation of the first drive motor in driving the plurality of fan blades in response to the reverse airflow is large. At this time, it is determined that the inclination angles of the plurality of fan blades in response to the reverse airflow are adjusted in the second adjustment manner.

[0055] Among them, the first adjustment method is to reduce the inclination angle of several of the fan blades, and the reduction range is 1.5°-3°. The present invention preferably reduces it by 2°, that is, the inclination angle of several of the fan blades after adjustment is 18°. At this time, several of the third drive motors drive several of the fan blades to rotate along the axis so that the initial inclination angle of several of the fan blades is reduced to 18°.

[0056] Among them, the second adjustment method is to reduce the initial inclination angle of several of the fan blades, and the reduction range is 3-5°. The present invention preferably reduces it by 4°, that is, the inclination angle of several of the fan blades after adjustment is 16°. At this time, several of the third drive motors drive several of the fan blades to rotate along the axis so that the initial inclination angle of several of the fan blades is reduced to 16°.

[0057] Specifically, the parameter adjustment module intelligently adjusts the fan blade inclination angle according to the torque fluctuation coefficient of the motor in the reverse airflow, thereby reducing the energy consumption of the first drive motor in driving the plurality of fan blades to counteract the reverse airflow, reducing the impact of the airflow on the fan blade surface, allowing the airflow to smoothly adhere to the blade surface, and reducing the separation phenomenon of the airflow and torque fluctuation, thereby improving the system energy efficiency ratio.

[0058] See also Figure 9 As shown, Figure 9 This is a logic block diagram for determining whether an adjustment method is qualified based on the average deviation value of the vibration amplitude in an embodiment of the present invention.

[0059] Specifically, the vibration monitoring module determines whether the adjustment mode for adjusting the initial inclination of the plurality of fan blades is qualified according to a comparison result of the average deviation value of the vibration amplitudes of the plurality of fan blades after the initial inclination of the plurality of fan blades is adjusted by the parameter regulation module and a preset average deviation value, wherein If the average deviation value is less than the preset average deviation value, it is determined that the adjustment mode for adjusting the initial inclination of the plurality of fan blades is qualified. If the average deviation value is greater than or equal to the preset average deviation value, it is determined that the adjustment mode for adjusting the initial inclination of the plurality of fan blades is unqualified. Preferably, the preset average deviation value is 0.2 mm, and the preferred value range and the preferred value of the preset vibration amplitude can be determined according to actual conditions, which are not limited here.

[0060] The average deviation value is obtained by first calculating the average value of the vibration amplitudes under the abnormal vibration times of the plurality of fan blades, then calculating the absolute difference value between the vibration amplitude under each abnormal vibration and the average value, and finally calculating the ratio of the sum of the absolute difference value to the abnormal vibration times.

[0061] Please refer to Figure 10 , Figure 10 The logic block diagram for determining the optimization mode according to the difference value in the embodiment of the application.

[0062] Specifically, under the condition that the adjustment mode is determined to be unqualified, the optimization module determines to optimize the adjustment mode according to a comparison result of the difference value between the average deviation value of the vibration amplitudes of the plurality of fan blades and the preset average deviation value and a preset difference value, wherein If the difference value is less than the preset difference value, it is determined to optimize the adjustment mode in a first optimization mode. If the difference value is greater than or equal to the preset difference value, it is determined to optimize the adjustment mode in a second optimization mode. Preferably, the preset difference value is 0.06 mm, and the preferred value range and the preferred value of the preset difference value can be determined according to actual conditions, which are not limited here.

[0063] In the embodiment of the present application, the first optimization mode is to keep the original adjustment direction, and further reduce the range of the first adjustment mode for adjusting the initial inclination angle of the plurality of blades and / or reduce the range of the second adjustment mode for adjusting the initial inclination angle of the plurality of blades, that is, in the first adjustment mode, the plurality of third driving motors drive the plurality of blades to rotate along the axis to change the original reduction of 2° to change the initial inclination angle of the plurality of blades to a reduction of 1.5° to optimize the first adjustment mode, and in the second adjustment mode, the original reduction of 4° to change the initial inclination angle of the plurality of blades is reduced to 3.5° to optimize the second adjustment mode.

[0064] In the embodiment of the present application, the second optimization mode is to reduce the initial rotation speed of the first driving motor on the basis of the first optimization mode, that is, to reduce the initial rotation speed of the first driving motor by 200-300 RPM, and the present application preferably takes a value of 240 RPM, and the rotation speed of the first driving motor after optimization is 1260 RPM.

[0065] Specifically, the adjustment of the plurality of blades is determined to be qualified or not by monitoring the vibration amplitude of the blades by the adjustment monitoring module, and the inclination angle of the plurality of blades is further optimized under unqualified conditions, which avoids the insufficient thrust of the plurality of blades on the air caused by insufficient adjustment of the plurality of blades and the phenomenon of serious airflow separation caused by airflow unable to adhere to the surface of the blades due to excessive adjustment, and the phenomenon of huge and unstable vortexes generated on the back of the blades, effectively controls the vibration of the plurality of blades in high-speed rotation, avoids fatigue damage of the blades and the first driving motor caused by frequent vibration, thereby prolonging the service life of the fan system, reducing turbulence and noise caused by vibration, and improving the stability and comfort of airflow output.

Those skilled in the art can make equivalent changes or replacements to related technical features without departing from the principles of the present application, and the technical solutions after these changes or replacements will fall within the protection scope of the present application.
