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 maintain high power operation for a long time.

[0053] The smart high-power multi-layer invisible fan lamp based on data points according to the embodiment of the application comprises:

[0054] A first structure layer 1, which is a mounting plate, is used to be connected with a pre-formed mounting part to fix the fan lamp;

[0057] A central shaft 9 is arranged through the first structure layer, the invisible fan layer and the second structure layer to provide axial support for the first structure layer, the invisible fan layer and the second structure layer.

[0058] In the embodiment of the application, the mounting 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.

[0059] In the embodiment of the application, the first driving part comprises a shell connected with the plurality of fan blades 3 and a first driving motor 4 arranged in the shell; the second driving part comprises a plurality of second driving motors 5 connected with the plurality of fan blades 3 to move the first driving part to fold the plurality of fan blades 3, and a plurality of third driving motors 6 connected with the plurality of fan blades 3 to change the angle of the plurality of fan blades 3; the surface of the first driving motor 4 is provided with a plurality of limiting grooves to limit the rotation of the plurality of second driving motors 5, so as to limit the change of the state of the plurality of fan blades.

[0060] In the embodiment of the 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.

[0061] The monitoring device comprises a temperature sensor 10 fixedly arranged on the upper portion of the first layer structure to monitor the temperature change of the indoor environment in real time, a current sensor 12 to monitor the current size input to 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;

[0062] The cooperative control unit is connected with the monitoring device and comprises:

[0063] The data acquisition module is connected with the monitoring device 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 to the first driving motor in the current working state;

[0064] The mode determination module is connected with the data acquisition module to determine whether the working mode of the invisible fan layer is executed according to the temperature value of the indoor environment in the current state monitored by the temperature sensor;

[0065] The air flow judgment module is connected with the mode determination module 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;

[0066] The state monitoring module is connected with the air flow judgment module and the mode determination module respectively to determine whether the working parameter of the plurality of fan blades is qualified according to the total number of peak torque 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;

[0067] The parameter adjustment module is connected with the state monitoring module to determine the adjustment of the initial inclination 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 parameter of the plurality of fan blades is unqualified;

[0068] The vibration monitoring module is connected with the parameter adjustment module to determine whether the adjustment mode of the inclination 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 parameter of the plurality of fan blades in the invisible fan layer;

[0069] The optimization module is connected with the parameter adjustment module and the vibration monitoring module respectively to determine the optimization of 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;

[0070] Specifically, by optimizing the structure of the fan light, the traditional hanging rod design of the fan light is eliminated, and a layered design is adopted. The first layer of the structure is firmly installed on the ceiling surface, which can enhance the stability of the fan light, effectively solve the safety hazards caused by the downward extension of the hanging rod, and reduce the occupation of indoor space. The layered design solves the problem of insufficient airflow caused by the inability to use a high-power drive motor due to the limited space of traditional fan lights.

[0071] Please see Figure 5 As shown, Figure 5 This is a logic block diagram illustrating how the invisible fan layer determines whether to execute a working mode based on the indoor temperature value, according to an embodiment of the present invention.

[0072] Specifically, the data acquisition module acquires the temperature value of the current indoor environment monitored by the temperature sensor, and the mode determination module determines whether the invisible fan layer should execute a working mode based on the comparison result between the current temperature value and a preset temperature value.

[0073] If the temperature value is less than the preset temperature value, it is determined that the invisible fan layer will not execute the working mode;

[0074] If the temperature value is greater than or equal to the preset temperature value, then the invisible fan layer is determined to be in working mode.

[0075] The preset temperature value ranges from 24 to 26°C, and the preferred value in this invention is 25°C. The preferred range and preferred value of the preset temperature value can be determined according to the actual situation, and are not specifically limited here.

[0076] In this embodiment of the invention, the preset temperature value is 25°C. During implementation, the working mode of the invisible fan layer is determined based on the comparison between the current ambient temperature and the preset temperature value. For example, if the temperature value is 22°C, it is less than the preset temperature value, indicating that the indoor temperature is low and no additional airflow is needed for cooling. In this case, the invisible fan layer is determined not to execute the working mode. Conversely, if the temperature value is 28°C, it is greater than the preset temperature value, indicating that the indoor temperature is high and additional airflow is needed for cooling. In this case, the invisible fan layer is determined to execute the working mode.

[0077] When the mode determination module determines that the invisible fan layer has started to execute the working mode, the working mode is that the second drive motor located at the connection between the first drive motor and the fan blades drives the fan blades to extend along the axis, so that the state of the fan blades changes from a converged state to an extended state, changing the initial state of the fan blades. When the second drive motor drives the fan blades to the limiting groove, it stops running. At this time, the fan blades are fully extended, the first drive motor starts to rotate, providing rotational power to the fan blades. At this time, the rotational speed of the fan blades increases, bringing airflow to the indoor environment and reducing the temperature of the indoor environment.

[0078] Specifically, the mode determination module automatically controls the operation mode of the invisible fan layer to cool the room when the indoor ambient temperature value monitored in real time by the temperature sensor is greater than the preset temperature value. When the indoor temperature is lower than the preset temperature value, the fan stops working, realizing intelligent temperature regulation, avoiding unnecessary energy waste, having a good energy-saving effect, and preventing the drive motor from being in a working state for a long time due to forgetting to turn off the fan, which would reduce the service life of the drive motor and reduce the later maintenance cost of the drive motor.

[0079] Please see Figure 6 As shown, Figure 6 This is a logic block diagram illustrating how the direction of airflow relative to the rotation of several fan blades is determined based on the trend of air resistance torque variation, according to an embodiment of the present invention.

[0080] Specifically, during the operation of the fan blades, the airflow determination module determines the direction of the airflow in the indoor environment relative to the fan blades based on the changing trend of the air resistance torque of the first drive motor, wherein...

[0081] If the trend of the change in air resistance torque is upward, then the airflow in the indoor environment is determined to be opposite to the rotation direction of some of the fan blades.

[0082] If the air resistance torque changes in a decreasing trend, then the airflow in the indoor environment is determined to be in the same direction as the rotation of the fan blades.

[0083] The air resistance torque is the torque consumed by the fan blades to overcome air resistance at a certain speed. This certain speed ranges from 1400-1600 RPM, and is preferably set to 1500 RPM in this invention. The air resistance torque is obtained by calculating the difference between the total torque of the fan at 1500 RPM and the no-load torque of the fan without blades. In practical applications, the current value input to the first drive motor at 1500 RPM is first acquired in real-time by the current sensor, which is 2A. Then, the torque constant of the first drive motor is obtained through its manufacturing specifications, which is 0.2. The total torque is calculated by multiplying the current value by the torque constant, which is 0.4 N·m. Further experiments are conducted to obtain the no-load current value flowing through the first drive motor when the fan speed is 1500 RPM (no fan blades, i.e., no-load state), which is 0.5 A. The no-load torque is then calculated by multiplying the no-load current value by the torque constant, 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.

[0084] In this embodiment of the invention, if the air resistance torque changes in an upward trend at the same rotation speed, that is, the value of the air resistance torque increases, it indicates that the airflow in the indoor environment is not in the same direction as the rotation of the fan blades. In this case, it is determined that the airflow in the indoor environment is opposite to the rotation direction of the fan blades.

[0085] Specifically, the airflow judgment module uses the trend of air resistance torque change during fan operation to determine the airflow direction in the indoor environment relative to the rotation direction of the fan blades. When the air resistance torque shows an upward trend, it is determined that the airflow direction in the indoor environment is opposite to the rotation direction of the fan blades, enabling the device to promptly detect the gas flow characteristics in the environment where the fan is currently operating.

[0086] Please see Figure 7 As shown, Figure 7 This is a logic block diagram illustrating how the operating parameters of several fan blades are determined based on the total number of peak torque cycles according to an embodiment of the present invention.

[0087] Specifically, the airflow judgment module determines that the airflow direction in the indoor environment is opposite to that of several fan blades. The status monitoring module then determines whether the operating parameters of the several fan blades are qualified based on a comparison between the total number of peak torque occurrences of the first drive motor and a preset total number of peak torque occurrences.

[0088] If the total number of peak torque counts is less than the preset total number of peak torque counts, then the operating parameters of several of the fan blades are determined to be qualified.

[0089] If the total number of peak torques is greater than or equal to the preset total number of peak torques, then the working parameters of several fan blades are determined to be unqualified, and the initial tilt angle of several fan blades is obtained.

[0090] The preset total number of peak torques ranges from 2 to 4 times, and the preferred value in this invention is 3 times. The preferred range and preferred value of the preset total number of times can be determined according to the actual situation, and no specific limitation is made here.

[0091] The total number of peak torques refers to the number of times the first drive motor can output the maximum torque when a number of fan blades are in response to the reverse airflow during the time period.

[0092] In this embodiment of the invention, the preset total number of peak torque occurrences is set to 2. During implementation, the working parameters of the fan blades are determined to be qualified based on the comparison between the total number of peak torque occurrences of the first drive motor and the preset total number of peak torque occurrences. For example, if the total number of peak torque occurrences is 1, it meets the condition that the total number of peak torque occurrences is less than the preset total number of peak torque occurrences, indicating that the first drive motor only outputs its maximum torque once to drive the fan blades to cope with the reverse airflow. In this case, the working parameters of the fan blades are determined to be qualified. For example, if the total number of peak torque occurrences is 5, it meets the condition that the total number of peak torque occurrences is greater than the preset total number of peak torque occurrences, indicating that the first drive motor outputs its maximum torque multiple times to drive the fan blades to cope with the reverse airflow. In this case, the working parameters of the fan blades are determined to be unqualified.

[0093] Wherein, the initial tilt angle is the tilt angle of the fan blades relative to the plane of rotation when dealing with the reverse airflow, and the value of this invention is 20°.

[0094] Specifically, by using the status monitoring module to determine whether the operating parameters of the fan blades are qualified by counting the number of times the peak torque occurs when the first drive motor overcomes the airflow direction in the opposite direction to the fan blades, it is possible to promptly detect whether the tilt angle of the fan blades is unqualified when dealing with the reverse airflow, thus avoiding mechanical damage caused by the first drive motor driving the fan blades for a long time under the condition of high air resistance.

[0095] Please see Figure 8 As shown, Figure 8 This is a logic block diagram of how the adjustment method is determined based on the torque fluctuation coefficient in an embodiment of the present invention.

[0096] Specifically, when the status monitoring module determines that the operating parameters of several fan blades are unqualified, the parameter adjustment module determines, based on a comparison between the torque fluctuation coefficient of the first drive motor when driving several fan blades at an initial tilt angle of 20° against the reverse airflow and a preset torque fluctuation coefficient, to adjust the initial tilt angle of several fan blades in response to the reverse airflow using a corresponding adjustment method.

[0097] If the torque fluctuation coefficient is less than the preset torque fluctuation coefficient, then it is determined that the tilt angle of the several fan blades in response to the reverse airflow is adjusted in the first adjustment mode.

[0098] If the torque fluctuation coefficient is greater than or equal to the preset torque fluctuation coefficient, then it is determined that the tilt angle of the several fan blades in response to the reverse airflow is adjusted in the second adjustment mode.

[0099] The preset torque fluctuation coefficient ranges from 0.3 to 0.5, and the preferred value in this invention is 0.4. The preferred range and preferred value of the preset torque fluctuation coefficient can be determined according to the actual situation, and no specific limitation is made here.

[0100] The torque fluctuation coefficient is obtained by the ratio of the difference between the maximum and minimum torque values ​​of the fan blades overcoming the reverse airflow under the drive of the first drive motor to the average torque value. In practical applications, the time period of overcoming the reverse airflow is divided into several time periods. The torque data output by the first drive motor driving the fan blades to overcome the reverse airflow is obtained in several time periods. The maximum and minimum torque values ​​in the torque data are selected, and the difference between the maximum and minimum torque values ​​is calculated. Then, the average value of the torque data is calculated. Finally, the ratio of the difference to the average value is calculated to obtain the torque fluctuation coefficient during the time period of overcoming the reverse airflow.

[0101] In this embodiment of the invention, the preset torque fluctuation coefficient is set to 0.4. During implementation, the tilt angle of the fan blades when dealing with the reverse airflow is adjusted according to a corresponding adjustment method based on the comparison between the torque fluctuation coefficient of the first drive motor driving the fan blades to overcome the reverse airflow and the preset torque fluctuation coefficient. For example, when the torque fluctuation coefficient is 0.25, it meets the condition that the torque fluctuation coefficient is less than the preset torque fluctuation coefficient, indicating that the fluctuation of the first drive motor driving the fan blades to overcome the reverse airflow is small during the time period. In this case, the tilt angle of the fan blades when dealing with the reverse airflow is adjusted according to a first adjustment method. For example, when the torque fluctuation coefficient is 0.6, it meets the condition that the torque fluctuation coefficient is greater than the preset torque fluctuation coefficient, indicating that the fluctuation of the first drive motor driving the fan blades to overcome the reverse airflow is large during the time period. In this case, the tilt angle of the fan blades when dealing with the reverse airflow is adjusted according to a second adjustment method.

[0102] The first adjustment method is to reduce the tilt angle of several fan blades, with the reduction range being 1.5°-3°. The present invention preferably reduces it by 2°, that is, the tilt angle of several fan blades after adjustment is 18°. At this time, several third drive motors drive several fan blades to rotate along the axis, so that the initial tilt angle of several fan blades is reduced to 18°.

[0103] The second adjustment method is to reduce the initial tilt angle of several fan blades, with the reduction range being 3-5°. The present invention preferably reduces it by 4°, that is, the tilt angle of several fan blades after adjustment is 16°. At this time, several third drive motors drive several fan blades to rotate along the axis, so that the initial tilt angle of several fan blades is reduced to 16°.

[0104] Specifically, the parameter adjustment module intelligently adjusts the blade tilt angle based on the torque fluctuation coefficient of the motor in the reverse airflow, which reduces the energy consumption of the first drive motor when driving several blades to resist the reverse airflow, reduces the impact of the airflow on the blade surface, allows the airflow to smoothly adhere to the blade surface, and reduces the separation phenomenon of the airflow, reduces torque fluctuation, thereby improving the system energy efficiency ratio.

[0105] Please see Figure 9 As shown, Figure 9 This is a logic block diagram illustrating how an adjustment method is deemed acceptable based on the average deviation of vibration amplitude, according to an embodiment of the present invention.

[0106] Specifically, after the vibration monitoring module adjusts the initial tilt angle of several fan blades based on the parameter control module, it determines whether the adjustment method for adjusting the initial tilt angle of several fan blades is qualified based on the comparison result of the average deviation value of the vibration amplitude of several fan blades after adjustment and the preset average deviation value.

[0107] If the average deviation value is less than the preset average deviation value, then the adjustment method of adjusting the initial tilt angle of the fan blades is deemed qualified.

[0108] If the average deviation value is greater than or equal to the preset average deviation value, then the adjustment method for adjusting the initial tilt angle of the fan blades is determined to be unqualified.

[0109] The preset average deviation value ranges from 0.1 to 0.3 mm, and the preferred value in this invention is 0.2 mm. The preferred range and preferred value of the preset vibration amplitude can be determined according to the actual situation, and are not specifically limited here.

[0110] The average deviation value is obtained by first calculating the average value of the vibration amplitude under several abnormal vibrations of the fan blades, then calculating the absolute difference between the vibration amplitude under each abnormal vibration and the average value, and finally calculating the ratio of the sum of the absolute differences to the number of abnormal vibrations.

[0111] Please see Figure 10 As shown, Figure 10 This is a logic block diagram of how the optimization method is determined based on the difference in an embodiment of the present invention.

[0112] Specifically, when the adjustment monitoring module determines that the adjustment method is unqualified, the optimization module determines to optimize the adjustment method based on a comparison between the average deviation value of the vibration amplitude of several fan blades and a preset average deviation value and a preset difference value.

[0113] If the difference is less than a preset difference, then the adjustment method is optimized using the first optimization method.

[0114] If the difference is greater than or equal to a preset difference, then the adjustment method is optimized using the second optimization method.

[0115] The preset difference value ranges from 0.05 to 0.07 mm, and the preferred value in this invention is 0.06 mm. The preferred range and preferred value of the preset difference can be determined according to the actual situation, and no specific limitation is made here.

[0116] In this embodiment of the invention, the first optimization method is to maintain the original adjustment direction and further reduce the range of adjustment of the initial tilt angle of the plurality of fan blades by the first adjustment method and / or reduce the range of adjustment of the initial tilt angle of the plurality of fan blades by the second adjustment method. That is, in the first adjustment method, the plurality of third drive motors drive the plurality of fan blades to rotate along the axis to reduce the original by 2° to change the initial tilt angle of the plurality of fan blades to 1.5° to optimize the first adjustment method. In the second adjustment method, the original by 4° is reduced to change the initial tilt angle of the plurality of fan blades to 3.5° to optimize the second adjustment method.

[0117] In this embodiment of the invention, the second optimization method is to reduce the initial speed of the first drive motor based on the first optimization method, that is, to reduce the initial speed of the first drive motor by 200-300 RPM. The preferred value in this invention is 240 RPM. After optimization, the speed of the first drive motor is 1260 RPM.

[0118] Specifically, by adjusting the monitoring module to monitor the vibration amplitude of the fan blades, it is determined whether the adjustment of the fan blades is qualified. If the adjustment is not qualified, the tilt angle of the fan blades is further optimized. This avoids insufficient thrust of the fan blades on the air due to insufficient adjustment of the fan blades, and severe airflow separation caused by over-adjustment, which prevents the airflow from adhering to the fan blade surface and generates huge, unstable vortices on the back of the blades. This effectively controls the vibration of the fan blades during high-speed rotation, avoids fatigue damage to the fan blades and the first drive motor caused by frequent vibration, thereby extending the service life of the fan system, reducing turbulence and noise caused by vibration, and improving the stability and comfort of airflow output.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
