As shown in fig. 1 to 2, an electric clothes drying member 002 includes a main body member 001 fixedly installed on a ceiling of an indoor balcony and a clothes drying member 002 below the main body member 001, and the clothes drying member 002 is connected to the main body member 001 via a pulling member 003. The main unit 001 has therein an MCU controller 004 and a driving motor 005. MCU controller 004 connects and controls driving motor 005, and traction part 003 is rope class part, and driving motor 005 control traction part 003 receive and releases, realizes the lifting function of clothing part 002 that dries in the air.
The user controls the driving motor 005 to rotate forward or backward or stop rotating by sending a control signal to the remote control, the wall control switch or the voice control module to the driving motor 005. When the driving motor 005 rotates clockwise, the clothes airing part 002 descends; when the driving motor 005 rotates counterclockwise, the clothes drying member 002 ascends.
As shown in fig. 3 to 5, the present embodiment provides a motor steering detection system, and the motor steering detection system provided in the present embodiment is specifically described below with reference to the accompanying drawings.
The motor steering detection system comprises a rotor 01, a stator 02, a first Hall sensor 07, a second Hall sensor 08 and an MCU controller 004; the first hall sensor 07 and the second hall sensor 08 sequentially sense the rotation of the rotor 01 and output signals, and the MCU 004 determines the steering of the rotor 01 by detecting the sensing sequence of the output signals of the first hall sensor 07 and the second hall sensor 08.
Moreover, the first hall sensor 07 comprises a magnetic element 04 and a first hall element 1, the second hall sensor 08 comprises a magnetic element 04 and a second hall element 2, the magnetic element 04 is installed on the rotor 01, the two hall elements are sequentially arranged on a rotation path of the rotor 01, and the magnetic element 04 is periodically and successively close to the hall elements.
Specifically, the motor steering detection system further includes a tailstock 03 for the rotor 01 to pass through, the rear end of the rotor 01 passes through the tailstock 03 to form an extension section 011, the magnetic element 04 is a magnetic ring 04 installed on the extension section 011, and the first hall element 1 and the second hall element 2 are arranged on the circuit board 05 on one side of the extension section 011. Preferably, the first hall element 1 and the second hall element 2 are laterally distributed parallel to each other.
Preferably, the magnetic ring 04 is in a long strip shape. When the magnetic ring 04 approaches the circuit board 05 in a rotating manner, signals of the first hall element 1 and the second hall element 2 are sequentially triggered, and the high level is changed to the low level.
In the operation process of the driving motor 005 of the electric clothes airing part 002, the motor steering detection system detects the rotation direction of the motor, and the detection principle is as follows:
when the driving motor 005 rotates, the two hall elements arranged side by side generate output signals with corresponding time difference due to different sequences of approaching and departing from the magnetic poles. The MCU controller 004 monitors the signal of the first hall element 1, determines that the driving motor 005 enters the operating state when the level of the first hall element 1 changes, and detects whether the signal of the second hall element 2 is identical to the first hall element 1, thereby determining the operating direction of the driving motor 005.
As shown in fig. 6, when the driving motor 005 operates in a clockwise direction, the first hall element 1 changes from a high level to a low level or from a low level to a high level; the first hall element 1 is triggered before the second hall element 2, at this time, the second hall element 2 is not triggered, the level signal is opposite to the first hall element 1, and the two signals monitored by the MCU 004 are not identical.
Similarly, as shown in fig. 7, when the driving motor 005 operates in the counterclockwise direction, the second hall element 2 is triggered before the first hall element 1, and before the second hall element 2 is triggered, the first hall element 1 has performed a corresponding level change, so that when the first hall element 1 is triggered, the level signal of the second hall element 2 is the same as that of the first hall element 1, and the two signals monitored by the MCU 004 are the same, so as to determine the operating direction of the driving motor 005.
In addition, the motor steering detection system further includes a hall signal detection circuit 09. The hall signal detection circuit 09 is connected with the MCU controller 004, and the hall signal detection circuit 09 sequentially collects output signals of the first hall sensor 07 and the second hall sensor 08 and feeds the output signals back to the MCU controller 004. The MCU controller 004 judges the running direction of the driving motor 005 by detecting the output signals of the first Hall sensor 07 and the second Hall sensor 08 which are acquired by the Hall signal detection circuit 09.
In addition, the hall signal detection circuit 09 may also detect whether the output level of one of the hall sensors changes during a period of time to determine the operation direction of the driving motor 005.
As shown in fig. 5 and 8, based on the above motor steering detection system, the present embodiment further provides a clothes dryer lifting stroke control system, which includes a first hall sensor 07, a second hall sensor 08, a driving motor 005, an MCU controller 004, and may further include a hall signal detection circuit 09 and a motor control circuit 010.
The first hall sensor 07 and the second hall sensor 08 sequentially sense the rotation of the rotor 01 of the driving motor 005 and output signals. The MCU controller 004 determines the operation direction of the driving motor 005 according to the motor steering detection system through the collected output signals of the first hall sensor 07 and the second hall sensor 08.
One of the hall sensors is selected for counting the number of rotations of the driving motor 005. By counting the hall signals, the number of running turns of the rotor 01 of the driving motor 005 can be accurately obtained. The MCU calculates the travel distance of the motor according to the conversion of the number of rotation turns, the reduction ratio of the motor and the diameter of the motor winch, and accurate data of the travel of the airing rod can be obtained.
The MCU controller 004 calculates the status of the airing rod according to the running direction and the distance of the driving motor 005, and controls the driving motor 005 to open or close according to the status.
In this embodiment, the motor control circuit 010 is connected to the driving motor 005 and the MCU controller 004, and the MCU controller 004 controls the driving motor 005 to open and close through the motor control circuit 010.
Preferably, the MCU controller 004 compares the number of turns of rotation acquired by one of the hall sensors with a threshold, and if the number of turns of rotation reaches the threshold, the MCU controller 004 instructs the driving motor 005 to stop operating by controlling the electronic switch. Further preferably, the electronic switch is a relay or thyristor.
When the count of the descending stroke of the motor is reduced by 1 and is less than or equal to zero, the MCU controller 004 stops driving the motor 005 to operate, and the clothes drying machine enters an upper limit protection state. And when the count of the descending stroke of the motor is more than or equal to the maximum threshold value plus 1, the MCU controller 004 stops driving the motor 005 to operate, and the clothes drying machine enters a lower limit protection state.
Compared with the traditional mode, the traditional detection mode of a single Hall can only count and detect the stroke of the motor, but cannot judge the running direction of the motor, and can only calculate the up-down stroke of the motor by combining with an output control signal under the controlled state of the motor. And the two parallel hall sensors of this embodiment can obtain the stroke and the direction of driving motor 005 simultaneously, when driving motor 005 receives inertial motion or passive motion, still can accurate calculation motor stroke to reduce the error of stroke calculation, guaranteed the reliability of airing machine operation.
The lifting stroke direction detection system, the motor steering detection system and the clothes airing machine provided by the invention are described in detail, specific examples are applied in the description to explain the principle and the implementation mode of the invention, and the description of the embodiments is only used for helping to understand the invention and the core idea. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
