Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioning, and particularly relates to equipment for introducing air indoors, and more particularly to an intelligent fan control device, a control system and a control method. Background Art

[0002] When the fan is used in the north or cold environment, the fan blades are easily covered with snow or frozen.

[0003] The traditional fan starts directly in a large-current mode. However, even if the fan is driven to operate in a large-current mode, the fan may not be able to break the ice. And if the fan continues to operate in a large-current mode, it is easy to cause damage to the fan. Even if the fan starts to break the ice in a large-current mode, there will still be snow remaining on the fan blades, resulting in an increase in the weight of the fan blades. On the one hand, it affects the accurate control of the fan. On the other hand, the inertia of the fan blades increases, and the fan blades get out of control directly during the deceleration process, posing a safety hazard.

[0004] Therefore, there is an urgent need to develop a new intelligent fan control device, a control system and a control method to solve the technical problem of how to safely start the fan when it is covered with snow or frozen.

[0033] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] The following will describe in detail some embodiments of the present invention with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0035] As Figures 1 to 6 , at least one embodiment provides an intelligent control device for a fan, which includes: a controller and an electromagnetic component 1; wherein the electromagnetic component 1 is located between the fan unit 23 and the housing 21 in the fan assembly 2, and the electromagnetic component 1 is connected to the fan unit 23; the electromagnetic component 1 is electrically connected to the controller; when the fan assembly 2 fails to start, the controller drives the electromagnetic component 1 to be energized to heat the fan assembly 2, so as to melt the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21, and the controller drives the motor unit 22 in the fan assembly 2 to swing the fan unit 23 reciprocally within a set angle range until the output signal of the controller is consistent with the feedback signal, and then the controller drives the motor unit 22 to rotate the fan unit 23 normally.

[0036] Specifically, when most of the fan unit 23 in the fan assembly 2 is covered or frozen, the motor unit 22 cannot drive the fan unit 23 to rotate. At this time, the motor unit 22 sends a feedback signal to the controller, that is, the fan assembly 2 fails to start. At this time, the controller drives the electromagnetic component 1 to be continuously energized, and the electromagnetic component 1 will generate heat, thereby heating the fan unit 23 and the housing 21, so that the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21 gradually melt. When the controller drives the motor unit 22 to attempt to drive the fan unit 23 to rotate, the controller sends an output signal to the motor unit 22, that is, to rotate a set angle within a set time. Then the motor unit 22 sends a feedback signal to the controller, the actual rotation angle within the set time, and gradually increases the set angle until the rotation angle set within the set time is equal to the actual rotation angle within the set time, that is, the output signal of the controller is consistent with the feedback signal. Then the controller can accurately control the motor unit 22, and finally the controller drives the motor unit 22 to rotate the fan unit 23 normally.

[0037] In at least one embodiment, by arranging the electromagnetic component 1 on the fan assembly 2, when the fan assembly 2 is covered with snow or frozen, heat is generated by the electromagnetic component 1, which can melt the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21, overcome the problem that the fan is damaged under continuous large current, and repeatedly debug before the fan assembly 2 starts normally until the fan assembly 2 meets the control accuracy and then starts normally, improving the control accuracy and operation safety.

[0038] In at least one embodiment, when the start of the fan assembly 2 is blocked, the controller drives the motor unit 22 to accelerate the rotation of the fan unit 23 to clean the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21; when the controller drives the motor unit 22 to decelerate the rotation of the fan unit 23, the controller drives the electromagnetic assembly 1 to be energized so that the electromagnetic assembly 1 generates a suction force on the housing 21, thereby hindering the rotation of the fan unit 23 until the set rotational speed is reached.

[0039] Specifically, when a small part of the fan unit 23 in the fan assembly 2 is covered, the motor unit 22 can drive the fan unit 23 to rotate. That is, at this time, the controller sends an output signal to the motor unit 22, that is, sets the set rotational speed of the motor unit 22. At this time, the motor unit 22 sends a feedback signal to the controller, that is, the actual rotational speed of the motor unit 22. However, the actual rotational speed is not equal to the set rotational speed. At this time, the controller determines that the start of the fan assembly 2 is blocked. By driving the motor unit 22 to accelerate the rotation of the fan unit 23 through the controller, the attachments on the fan unit 23 can be thrown out or scraped off the obstacles on the inner side wall of the housing 21.

[0040] Specifically, due to the possible existence of attachments on the fan unit 23, the controller cannot accurately control the motor unit 22 to drive the fan unit 23 to rotate. When the controller drives the motor unit 22 to decelerate, the fan unit 23 is definitely overweight due to the attachments. If only relying on the controller to drive the motor unit 22, there is a risk of out-of-control. By driving the electromagnetic assembly 1 to be continuously energized through the controller, the electromagnetic assembly 1 will generate a magnetic field, that is, the electromagnetic assembly 1 generates a suction force on the housing 21, which can provide an additional resistance to the fan unit 23, offset the additional gravity on the fan unit 23, and thus eliminate the risk of out-of-control.

[0041] In at least one embodiment, the electromagnetic assembly 1 includes: a plurality of electromagnetic modules 11; each of the electromagnetic modules 11 is respectively arranged on the fan unit 23, and each of the electromagnetic modules 11 is electrically connected to the controller; when the controller obtains a feedback signal and senses that the start of the motor unit 22 fails, the controller drives each of the electromagnetic modules 11 to be energized for heating to melt the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21; when the controller drives the motor unit 22 to decelerate the rotation of the fan unit 23, the controller drives each of the electromagnetic modules 11 to be energized so that each of the electromagnetic modules 11 generates a suction force on the housing 21.

[0042] Specifically, when the electromagnetic module 11 is energized, heat is generated, which can melt the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21.

[0043] Specifically, when the electromagnetic module 11 is energized, a magnetic field is generated, and the fan unit 23 is braked by the suction force.

[0044] In at least one embodiment, each electromagnetic module 11 is electrically connected to the slip ring inside the motor unit 22; when the motor unit 22 and each electromagnetic module 11 are powered on at the same time, the motor unit 22 is divided by each electromagnetic module 11 to reduce the rotation speed of the motor unit 22.

[0045] Specifically, the electromagnetic module 11 and the motor unit 22 are powered by slip rings, so that each electromagnetic module 11 is connected in series with the motor unit 22. When the motor unit 22 is decelerating, each electromagnetic module 11 can divide the voltage, thereby reducing the voltage on the motor unit 22 and improving the speed reduction effect of the motor unit 22.

[0046] In at least one embodiment, the electromagnetic module 11 includes: an electromagnet 111; the electromagnet 111 is arranged in a strip or sheet shape, the electromagnet 111 is connected to the fan unit 23, and the electromagnet 111 is electrically connected to the controller; a magnetic metal layer 211 is arranged on the inner wall of the shell 21, and the electromagnet 111 is located next to the magnetic metal layer 211.

[0047] Specifically, the electromagnet 111 can generate heat and a magnetic field when powered on, and cooperate with the magnetic metal layer 211 to provide a braking force on the fan unit 23 .

[0048] Based on the same technical concept, at least one embodiment also provides a control system, which includes: a controller, a fan assembly 2 and an electromagnetic assembly 1; wherein the electromagnetic assembly 1 is located between the fan unit 23 and the shell 21 in the fan assembly 2, and the electromagnetic assembly 1 is connected to the fan unit 23; the electromagnetic assembly 1 is electrically connected to the controller; when the fan assembly 2 fails to start, the controller drives the electromagnetic assembly 1 to energize and heat the fan assembly 2 to melt the attachments on the fan unit 23 and the obstacles on the inner wall of the shell 21, and the controller drives the motor unit 22 in the fan assembly 2 within a set angle range The fan unit 23 is swung back and forth until the output signal of the controller is consistent with the feedback signal, and the controller drives the motor unit 22 to rotate the fan unit 23 normally; when the start-up of the fan assembly 2 is blocked, the controller drives the motor unit 22 to accelerate the rotation of the fan unit 23 to clean the attachments on the fan unit 23 and the obstructions on the inner wall of the shell 21; when the controller drives the motor unit 22 to reduce the speed of the fan unit 23, the controller drives the electromagnetic assembly 1 to energize, so that the electromagnetic assembly 1 generates suction to the shell 21, thereby hindering the rotation of the fan unit 23 until the set speed is reached.

[0049] Specifically, the controller cooperates with the fan assembly 2 and the electromagnetic assembly 1 to achieve closed-loop control.

[0050] In at least one embodiment, the fan assembly 2 includes: a housing 21, a motor unit 22, and a fan unit 23; the motor unit 22 is installed in the housing 21, the fan unit 23 is movably connected to the motor unit 22, and the motor unit 22 is electrically connected to a controller; the controller sends a corresponding output signal to the motor unit 22 to cause the motor unit 22 to rotate according to the output signal; the motor unit 22 obtains rotation data and forms a corresponding feedback signal and sends it to the controller.

[0051] In at least one embodiment, the motor unit 22 includes: a motor drive module and a rotating motor 221; the rotating motor 221 is electrically connected to the motor drive module, and the rotating motor 221 is installed in the housing 21; the motor drive module is electrically connected to the controller; the controller sends a corresponding output signal to the motor drive module to cause the motor drive module to drive the rotating motor 221 to rotate according to the output signal; the motor drive module collects the rotation data of the rotating motor 221 to form a corresponding feedback signal and sends it to the controller; the fan unit 23 includes: a rotating shaft 231 and a plurality of fan blades 232; one side of the rotating shaft 231 is connected to the rotating motor 221, and the fan blades 232 are circumferentially distributed around the other side of the rotating shaft 231; the rotating motor 221 drives the rotating shaft 231 and the fan blades 232 to rotate.

[0052] Specifically, on the one hand, the motor drive module functions to drive the rotating motor 221, and on the other hand, it can feedback the state of the rotating motor 221 to the controller.

[0053] In at least one embodiment, the electromagnetic assembly 1 includes: a plurality of electromagnetic modules 11; each of the electromagnetic modules 11 is respectively disposed at the distal shaft end of the corresponding fan blade 232, and each of the electromagnetic modules 11 is electrically connected to the controller; when the controller obtains a feedback signal and senses that the rotation motor 221 fails to start, the controller drives each electromagnetic module 11 to be energized to heat the fan assembly 2, so as to melt the attachments on each fan blade 232 and the obstacles on the inner side wall of the housing 21; when the controller drives the rotation motor 221 to drive each fan blade 232 to rotate at a reduced speed through the motor drive module, the controller drives each electromagnetic module 11 to be energized, so that each electromagnetic module 11 generates a suction force on the housing 21; each of the electromagnetic modules 11 is electrically connected to the slip ring in the rotation motor 221; when the rotation motor 221 and each electromagnetic module 11 are energized simultaneously, the rotation motor 221 is voltage-divided by each electromagnetic module 11 to reduce the rotation speed of the rotation motor 221; the electromagnetic module 11 includes: an electromagnet 111; the electromagnet 111 is arranged in a strip shape or a sheet shape, the electromagnet 111 is connected to the distal shaft end of the fan blade 232, and the electromagnet 111 is electrically connected to the controller; a magnetic metal layer 211 is arranged on the inner side wall of the housing 21, and the electromagnet 111 is located beside the magnetic metal layer 211.

[0054] Based on the same inventive concept, at least one embodiment further provides a control method using the control system as described above, which includes: when the fan assembly 2 fails to start, the controller drives the electromagnetic assembly 1 to be energized for heating, so as to melt the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21, and the controller drives the motor unit 22 in the fan assembly 2 to swing the fan unit 23 reciprocally within a set angle range until the output signal of the controller is consistent with the feedback signal, and then the controller drives the motor unit 22 to rotate the fan unit 23 normally; when the start of the fan assembly 2 is blocked, the controller drives the motor unit 22 to rotate the fan unit 23 at an accelerated speed, so as to clean the attachments on the fan unit 23 and the obstacles on the inner side wall of the housing 21; when the controller drives the motor unit 22 to rotate the fan unit 23 at a reduced speed, the controller drives the electromagnetic assembly 1 to be energized, so that the electromagnetic assembly 1 generates a suction force on the housing 21, thereby hindering the rotation of the fan unit 23 until the set rotation speed is reached.

When there is an intermediate component between the first component and the second component other than a wire, trace, or another medium, the first component is indirectly coupled to the second component. The term "coupled" and its variants include both direct coupling and indirect coupling. Unless otherwise specified, the use of the term "about" means including a range of plus or minus 10% of the numerical value.

[0064] Although several embodiments are provided in the present disclosure, it should be understood that the disclosed systems and methods may be embodied in many other specific forms without departing from the spirit or scope of the present disclosure. The current examples are considered illustrative rather than restrictive and are not limited to the details given. For example, various elements or components may be combined or integrated into another system, or some features may be omitted or not implemented.

[0065] In several embodiments provided herein, it should be understood that the disclosed apparatus and methods may also be implemented in other ways. The apparatus embodiments described above are merely illustrative. For example, the flowcharts and block diagrams in the figures show the possible architectures, functions, and operations of apparatus, methods, and computer program products according to multiple embodiments of the present invention. In this regard, each block in the flowchart or block diagram may represent a module, a program segment, or a part of code that contains one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions marked in the blocks may occur in a different order than marked in the figures. For example, two consecutive blocks may actually be executed substantially in parallel, and they may sometimes be executed in the reverse order, depending on the functions involved. It should also be noted that each block in the block diagram and / or flowchart, and combinations of blocks in the block diagram and / or flowchart, may be implemented by a dedicated hardware-based system for performing the specified functions or actions, or may be implemented by a combination of dedicated hardware and computer instructions.

[0066] In addition, without departing from the scope of the present disclosure, the discrete or separate technologies, systems, subsystems, and methods described and illustrated in various embodiments may be combined or integrated with other systems, modules, technologies, or methods. Other items shown or discussed as being coupled may be directly connected, or may be indirectly coupled or communicate electrically, mechanically, or otherwise through some interface, device, or intermediate component.
