Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
Fig. 1, 2 and 3 show an embodiment of a fan assembly of the present invention, which includes a fan frame 10 and a fan 20 rotatably disposed in the fan frame 10, and further includes a photoelectric switch 30 and a stroke path component 40, wherein the photoelectric switch 30 is disposed on the fan frame 10, the stroke path component 40 is disposed on the fan 20, and the stroke path component 40 is matched with the photoelectric switch 30. As shown in fig. 3 and 4, in use, the fan 20 starts to rotate relative to the fan housing 10, and the end of the stroke track component 40 triggers the photoelectric switch 30; in the process that the fan 20 continuously rotates relative to the fan frame body 10, the stroke track component 40 continuously triggers the photoelectric switch 30; after the fan 20 is rotated to the right position relative to the fan frame 10, the end of the stroke track part 40 is separated from the photoelectric switch 30 to stop triggering the photoelectric switch 30.
By applying the technical scheme of the invention, the fan 20 rotates to drive the stroke track part 40 to move to be matched with the photoelectric switch 30, so that the rotation of the fan 20 and whether the fan 20 rotates in place can be completely detected, and the control precision of the rotation of the fan 20 is further improved.
In addition, compared with the prior art, the technical scheme of the invention can avoid unnecessary noise generated by the collision of the two stop blocks.
Optionally, in the technical solution of the present invention, the optoelectronic switch 30 includes two sides, one side is a signal transmitting end, and the other side is a signal receiving end. When the fan 20 is not rotating, the stroke track component 40 is disengaged from the photoelectric switch 30, and the signal receiving end of the photoelectric switch 30 can receive the signal, which is the state that the stroke track component 40 does not trigger the photoelectric switch 30. When the fan 20 needs to turn, the end of the stroke track part 40 is blocked between the signal transmitting end and the signal receiving end, and the signal receiving end of the photoelectric switch 30 cannot receive a signal, which is to trigger the photoelectric switch 30.
Alternatively, as shown in fig. 3, the stroke trace member 40 is provided on the surface of the fan 20 and protrudes with respect to the surface of the fan 20.
As another alternative embodiment not shown in the drawings, the photoelectric switch 30 is provided on the blower 20, and the stroke trajectory part 40 is provided on the blower housing 10. In this embodiment, the stroke trace member 40 is provided on the surface of the fan housing 10, and protrudes with respect to the surface of the fan housing 10.
As shown in fig. 3 and 4, in the present embodiment, the stroke trajectory part 40 has a bar shape. Preferably, in the solution of the present embodiment, the stroke track component 40 is arc-shaped, and the arc-shaped stroke track component 40 completely overlaps with the movement track of the fan 20, so that the stroke track component 40 can be prevented from interfering with the photoelectric switch 30 during the rotation process. Because in the technical solution of the present embodiment, the fan 20 needs to rotate 180 ° to complete the turning, the stroke track component 40 is in a semi-circular arc shape. As an alternative, if the fan 20 is required to be rotated 90 °, it is possible to use 1/4.
As other alternative embodiments, a zigzag or curved path segment 40 is also possible, and with a path segment 40 of this design, the distance between the two sides of the optoelectronic switch 30 is appropriately set, so that interference problems can also be avoided.
In addition to the two embodiments shown in the figures, the photoelectric switch 30 and the stroke path component 40 may be installed at other positions where the blower housing 10 and the blower 20 are engaged with each other.
As shown in fig. 4, which shows the cooperation of the stroke track component 40 and the optoelectronic switch 30, as another alternative embodiment, the stroke track component 40 may be designed on both the left and right sides according to the design requirement, and when the steering of one cycle is completed, the left and right positions are interchanged. The travel path component 40 in fig. 3 and 4 is the preferred solution of the present invention, but the travel path component 40 can be designed in other positions in fig. 3 or 4 according to actual requirements to achieve the same purpose.
The invention also provides a control method of the fan assembly, and the control method is used for controlling the fan assembly. The control method comprises the steps of controlling the fan 20 to rotate relative to the fan frame body 10 and receiving a signal of the photoelectric switch 30, and when the signal of the photoelectric switch 30 is changed from a receiving state to an interruption state, continuously controlling the fan 20 to rotate relative to the fan frame body 10; when the signal of the photoelectric switch 30 is changed from the interrupt state to the reception state, the rotation of the fan 20 with respect to the fan housing 10 is stopped. Specifically, as shown in fig. 4, when steering is required, the driving assembly is turned on to control the fan 20 to rotate, the travel track component 40 starts to enter the photoelectric switch 30, and the signal of the photoelectric switch 30 is changed from a receiving state to an interrupting state; when the stroke trace part 40 completely passes through the photoelectric switch 30, the signal of the photoelectric switch 30 changes from the interruption state to the reception state.
The travel path component 40 of fig. 4 is turned to the symmetrical left end to complete the reversing, and the driving assembly can be controlled to stop working at this time to achieve the reversing positioning function. In the same way, when the direction needs to be changed again, the operation is repeated, the driving assembly rotates reversely, the direction changing purpose is achieved, and the wind of the fan wire is avoided due to the forward and reverse rotation.
More preferably, when the signal of the photoelectric switch 30 changes from the receiving state to the interrupting state, the timing is performed; when the signal of the photoelectric switch 30 is changed from the interruption state to the receiving state, the timing is stopped; and if the timing time exceeds the preset time, sending out warning information to warn the fan 20 of abnormal steering. Specifically, the driving component is a stepping motor. The preset time is specified according to the step number of the stepping motor during design, if the timing time exceeds the preset time, namely the stepping motor does not turn in place, warning information is sent to warn the fan 20 of abnormal turning, and a user is informed of finding problems and solving problems in time conveniently.
As an alternative embodiment, the timing may be a timing module in a plc type controller, and the timing module is used for timing when the signal of the optoelectronic switch 30 changes from the receiving state to the interrupting state. As another alternative, the timer may be a separately provided timing device.
The invention also provides an air conditioning unit, wherein the fan assembly of the air conditioning unit is the fan assembly, and the air conditioning unit adopting the fan assembly can realize accurate steering of the fan and reduce noise generated in the steering process.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the embodiment of the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
