Detailed Description

For the purpose of making the objects, technical solutions and advantages of some embodiments of the present application more clear, the technical solutions of some embodiments of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application.

It should be noted that the brief description of the terms in some embodiments of the present application is only for convenience in understanding the embodiments described below, and is not intended to limit the implementation of some embodiments of the present application. Unless otherwise indicated, these terms should be construed in their ordinary and customary meaning.

In this embodiment, as shown in fig. 1, the window body includes an outer frame 1, a movable fan 2, and a fixed fan 3. Wherein, frame 1 installs on the building window wall body, can be rectangular frame structure. The movable fan 2 and the fixed fan 3 are both arranged in the outer frame 1, but the fixed fan 3 is fixedly arranged in the outer frame 1, and the movable fan 2 is movably arranged in the outer frame 1. The movable fan 2 and the fixed fan 3 can be rectangular frame structures, and the movable fan 2 and the fixed fan 3 can be provided with glass and other blocking materials, and the movable fan 2 and the fixed fan 3 can completely seal the outer frame 1 to seal the space in the building when the movable fan 2 is in a closed state.

As shown in fig. 2, the fixed fan 3 may be disposed in an area surrounded by the outer frame 1, on a side where the ventilation is not required, and the movable fan 2 may be disposed on a side where the ventilation is required. For example, for a vertical opening/closing type window, the fixed fan 3 is fixed to the lower portion of the outer frame 1, and the movable fan 2 is provided to the upper portion of the outer frame 1, and the movable fan 2 can move in the vertical direction. When the ventilation is required, the movable fan 2 is moved down to open the upper region of the window for ventilation, and when the ventilation is not required, the movable fan 2 is moved up to close the upper region of the window.

In some embodiments, as shown in fig. 3 and 4, in order to facilitate the movement of the movable fan 2, a slide 11 for assisting the movement of the movable fan 2 may be provided on the outer frame 1. For a vertical opening and closing window, the slide 11 may be provided on two uprights of the outer frame 1. The movable fan 2 is provided with a sliding shaft 21, and the sliding shaft 21 can move in the slideway 11. For example, for a vertical opening and closing window, two upright posts of the outer frame 1 are provided with S-shaped slide ways 11, and sliding shafts 21 are respectively arranged at the top and bottom positions of two sides of the movable fan 2, wherein the sliding shafts 21 protrude out of side profiles of the movable fan 2. After assembly, the sliding shaft 21 can enter the slide way 11 and move relative to the slide way 11, so that the sliding shaft 21 can drive the whole movable fan 2 to move along the slide way 11, and the window body can be opened and closed.

In the opening and closing process of the window body, the movable fan 2 can be driven by a driving device, wherein the driving device can be arranged at the top of the outer frame, and the inside of the frame profile of the movable fan 2 or the fixed fan 3 can also be arranged. As shown in fig. 1, in some embodiments, the driving device includes a window machine 4 and a transmission mechanism, where the transmission mechanism may include a transmission component traction rope and a lifting pulley block, and the window machine 4 may be a driving motor, and the driving click is connected to one end of the traction rope through the transmission component, and the other end of the traction rope is connected to the movable fan 2 through the lifting pulley block. In the window opening process, the driving motor rotates positively, and the traction rope is loosened through the transmission part, so that the movable fan 2 moves downwards along the slideway, and the opening of the window is increased; in the window closing process, the driving motor rotates reversely, and the traction rope is tightened through the transmission part, so that the movable fan 2 moves upwards along the slideway, and the opening of the window is reduced.

The connection relationship among the outer frame 1, the movable fan 2, and the window unit 4 may be the same as that provided in the above embodiment, or may be connected in other manners. For example, the movable fan 2 and the window machine 4 can be connected through a ball screw, and the movable fan 2 and the window machine 4 can also be connected through a worm gear. The outer frame 1 and the movable fan 2 can be movably connected through sliding grooves and sliding blocks, the outer frame 1 and the movable fan 2 can be movably connected through guide rods, and the specific connection mode is not limited.

The opening degree refers to the opening degree of the window movable fan 2 relative to the outer frame 1, that is, the greater the opening degree is, the higher the opening degree of the movable fan 2 relative to the outer frame 1 is, and the better the ventilation effect is; the smaller the opening degree is, the lower the opening degree of the movable fan 2 relative to the outer frame 1 is, and the better the sealing effect is.

Therefore, in the above embodiment, the movable fan 2 is driven by the window frame 4 to move, so that in the process of opening and closing the window, the frame profile and the glass of the movable fan 2 have a certain weight, so that the movable fan 2 can only stay at the position of being fully opened or fully closed under the action of gravity for the vertical opening and closing window, namely, can only be fully opened or closed by one key, and cannot realize the opening adjustment of the window.

In order to realize adjustment of the window opening, some embodiments of the present application further provide a window opening adjustment system, as shown in fig. 2, where the system includes: a signal input device, an opening detection device 5, a controller, a driving device and a window sash; the signal input device, the opening detection device 5 and the driving device are in communication connection with the controller; the driving device is connected with the window sash;

wherein the signal input device is configured to input an opening degree adjustment instruction; the opening degree detection device 5 is configured to detect opening degree information of the window sash, which is one or more combinations of position information, time information, displacement information, and angle information.

The controller is configured to:

responding to the opening adjustment instruction, and analyzing a target opening from the opening adjustment instruction, wherein the target opening is a preset percentage of the total moving stroke of the window sash;

acquiring opening degree information detected by the opening degree detection device 5;

and generating a driving instruction according to the target opening degree and the opening degree information, and sending the driving instruction to the driving device so that the driving device drives the window sash to move to a position corresponding to the target opening degree.

The signal input device can be arranged on the outer frame 1, the movable fan 2, the fixed fan 3 and the wall near the window body, and can also be a terminal device held by a user. The opening degree detecting means 5 may be provided on the casing 1 and/or the movable fan 2, and the opening degree detecting means 5 is connected to the controller for detecting opening degree information of the movable fan 2, such as current position information or the like, and transmitting the opening degree information to the controller. The controller is connected with the driving device, and after receiving the opening degree information sent by the opening degree detection device 5, the controller can judge the opening degree information and control the driving device to move according to the judging result so as to start and stop according to the opening degree information. Therefore, the controller controls the driving device to start and stop according to the opening degree information, namely, after the movable fan 2 moves to a specific position, the window machine 4 is controlled to stop running, and then the movable fan 2 stays at the current position, so that the window opening degree is adjusted.

According to different window application scenes, window opening adjustment can be divided into two modes of arbitrary position adjustment and specific position adjustment. The optional position adjusting controller can control the driving device to start and stop at any position within the stroke range of the movable fan 2, so that the movable fan 2 stays at any position. The specific position adjustment can control the movable fan 2 to move according to a plurality of specific position points set (or factory set) by a user, namely when the movable fan 2 moves to the specific position points, the movable fan 2 is triggered to start or stop so as to adjust the opening of the window according to the set specific position points.

For example, according to the user setting, the window opening degrees may be set to be 25%, 50%, 75% and 100% respectively, and the position of the movable fan 2 is detected in real time during the movement of the movable fan 2, and when the movable fan 2 reaches the position point corresponding to the 25% opening degree selected by the user, the window machine 4 automatically stops operating, so as to implement adjustment of the 25% window opening degree. Similarly, when the user selects 50%, 75% and 100% of opening degrees, when detecting that the movable fan 2 reaches the corresponding position, the window machine 4 is triggered to automatically stop running, so that the corresponding opening degree is adjusted.

The opening detection device 5 can detect the position information of the movable fan 2 based on different detection principles. The detection principle of the position information of the movable fan 2 may be direct detection and/or indirect detection. The opening degree detection device 5 may directly detect, that is, directly acquire the position information of the movable fan 2 by a sensor or the like, for example, the position information of the movable fan 2 may be acquired based on the rotation angle (number of turns) of the window machine 4, the operation time of the window machine 4, the position sensor, and the like.

The following description will be made with reference to several specific examples of the detection process of the position information by the opening degree detection device 5 and the control process of the window opening degree adjustment system, and it should be understood that the following examples are only a few of the possible embodiments of the present application, and other examples that can be considered by those skilled in the art without any inventive effort are also within the scope of protection of the present application.

Embodiment one.

As shown in fig. 5, in the present embodiment, the opening degree detecting device 5 may be provided on the window 4 to detect the operation state of the window 4, thereby realizing window opening degree adjustment. Thus, the driving device comprises a window machine 4 and a transmission mechanism, wherein the window machine 4 is connected with the movable fan 2 through the transmission mechanism; the window unit 4 comprises a power output shaft 41, and the power output shaft 41 is connected with the transmission mechanism.

In some embodiments, window unit 4 may also include a self-locking mechanism 42. Wherein, self-locking mechanism 42 connects power take off shaft 41, and self-locking mechanism 42 is used for locking power take off shaft 41 when window machine 4 stops rotating.

To be able to lock the power take-off shaft 41, the self-locking mechanism 42 may comprise an electromagnetic power-off brake. Taking an electrified electromagnetic attraction as an example, an outage friction braking type brake, the electromagnetic outage braking type brake can comprise a magnetic yoke, an excitation coil, a spring, a braking disc, an armature, a spline housing, a mounting screw and the like. The electromagnetic power-off brake is arranged at the shaft end of a power output shaft 41 (rotor) of the motor of the window machine 4, and when the window machine 4 stops supplying power, the electromagnetic power-off brake can automatically band-type brake, so that the power output shaft 41 stops rotating, and the self-locking purpose is achieved. It is obvious that the self-locking mechanism 42 may also be self-locking based on other self-locking principles, for example, a mode of adding a position ring on a servo motor, a mode of installing a ratchet mechanism on the power output shaft 41, etc.

When the window machine 4 comprises the self-locking mechanism 42, the self-locking function of the self-locking mechanism 42 can be utilized to control the movable fan 2 to move or stop moving, so as to achieve the purpose of adjusting the opening of the window. The self-locking mechanism 42 can prevent the power output shaft 41 of the window machine 4 from rotating at any time, so that the opening degree of the window body at any position can be adjusted based on the self-locking mechanism 42. For example, a user may input an opening adjustment command through a signal input device such as a remote controller or a control panel on the window, and the window 4 starts to rotate in response to the opening adjustment command and drives the movable fan 2 to move downward, so as to increase the opening of the window. When the opening degree is proper, the user can send a stop instruction through the remote controller or the control panel on the window body, and the window machine 4 is powered off to stop rotating in response to the stop instruction, so that the movable fan 2 stops moving downwards, and the current opening degree of the window body position is achieved.

It can be seen that, in the first embodiment, the self-locking mechanism 42 is installed on the window machine 4, so that the window can be stopped at any position in the stroke of the movable fan 2 by utilizing the self-locking action of the window machine 4, and the opening of the window can be adjusted according to the control of the user, so as to meet the ventilation requirement of the user.

In the first embodiment, since the opening of the window is adjusted according to the user control, that is, the user needs to input the stop command while waiting for the movable fan 2 to move to the appropriate position, the complexity and waiting time of the user operation are increased. In order to improve the user, the opening detection device 5 can be matched with the self-locking mechanism 42 on the window machine 4 to realize the adjustment at a specific position.

Embodiment two.

As shown in fig. 6, the present embodiment differs from the above-described embodiment in that the opening degree detection device 5 includes an angle sensor 51. The angle sensor 51 is one or more of a rotary potentiometer, a grating disk and an angle encoder connected with the power output shaft 41. An angle sensor 51 is connected to the power output shaft 41 of the window machine, the angle sensor 51 is also electrically connected to the controller, the angle sensor 51 is configured to detect the rotation angle of the power output shaft 41 and send the rotation angle to the controller;

the controller is further configured to: and calculating a target rotation angle according to the target opening degree, and generating the driving instruction according to the rotation angle and the target rotation angle so as to start and stop the window machine 4 according to the rotation angle.

In the process of adjusting the specific position, according to the model specification of the window machine 4 and the moving stroke of the movable fan 2, the functional relationship between the rotating angle of the window machine 4 and the moving distance of the movable fan 2 can be recorded in advance, namely, the corresponding angle of the window machine 4 to be rotated is determined when the movable fan 2 moves by 1 mm. After determining the functional relationship between the rotation angle and the movement distance, the angle sensor 51 may record the rotation angle of the window machine 4 during the operation of the window machine 4, send the detected rotation angle to the controller, and when the controller determines that the rotation angle reaches the set angle, automatically generate a stop signal and send the stop signal to the window machine 4, and after receiving the stop signal, the window machine 4 stops rotating and self-locks by the self-locking mechanism 42, so that the movable fan 2 stops at a specific position.

For example, it is recorded in advance that each time the movable fan 2 moves by 1mm, the window machine 4 rotates 360 °, the total stroke of the movable fan 2 is 1m (i.e., 1000 mm), and the following four specific positions may be divided according to the stroke, i.e., the opening degrees are respectively: 25%, 50%, 75% and 100%. The distances that the movable fans 2 need to move are respectively: 250mm, 500mm, 750mm, 1000mm, so according to the recorded functional relation, the rotation angles of the window machine 4 corresponding to four specific positions can be determined as follows: 90000 °, 180000 °, 270000 °, 360000 °.

After determining the functional relation between the rotation angle and the moving distance, the user can select a specific position, such as a 25% opening position, through a remote controller or a control panel on the window body, and input an opening adjustment command, then the controller can start to operate to drive the movable fan 2 to move downwards in response to the opening adjustment command, meanwhile, the angle sensor 51 detects the rotation angle of the window machine 4 and sends the detected rotation angle to the controller, the controller judges whether the rotation angle reaches 90000 degrees according to the rotation angle sent by the angle sensor 51, and when the rotation angle reaches 90000 degrees, a stop command is generated to stop the window machine 4 from rotating and enable the movable fan 2 to stay at a position 250mm away from the outer frame top beam.

It should be noted that, because the manner of determining the opening of the window according to the rotation angle is affected by the initial movement position of the movable fan 2, in the control process of starting and stopping the window machine 4 according to the rotation angle, the controller can record the rotation angle in real time, and modify the recorded rotation angle in real time according to the movement process of the movable fan 2, so that after the user inputs the opening adjustment instruction, the controller can calculate the angle that the window machine 4 needs to rotate according to the recorded angle and the angle of the position corresponding to the specific opening, and operate according to the angle that needs to rotate.

Obviously, the transmission process between the window machine 4 and the movable fan 2 is to convert the rotation of the window machine 4 into the movement of the movable fan 2, and when the movement stroke of the movable fan 2 is far, the window machine 4 is required to rotate continuously, so that the detected rotation angle value is large when the window machine 4 is controlled to start or stop according to the rotation angle, and the data acquisition amount of the sensor and the data processing amount of the window machine 4 are increased. To this end, in some embodiments, the number of turns may be used instead of the angle of rotation to make the determination of the start-stop condition.

Embodiment three.

The present embodiment differs from the above embodiment in that the angle sensor 51 is a grating disk connected to the power output shaft 41, and the grating disk is used to detect the number of rotations of the power output shaft 41 of the window machine 4. For example, as shown in fig. 6, a light hole may be formed in the grating disk, a light shielding member protruding from the circumferential surface may be formed on the power output shaft 41, and the light shielding member may shield the light hole along with rotation of the power output shaft 41, that is, the light shielding member may shield the light hole once every time the power output shaft 41 rotates. The both sides of light trap can be equipped with light emitting device and light receiving device respectively, and the light that light emitting device launched can shine on light receiving device through the light trap, then when the light trap was sheltered from by the light shielding piece, light receiving device can detect a light variation signal. Therefore, each time the light receiving device detects that the light transmitting hole is blocked, it means that the power output shaft 41 rotates one revolution, and the number of revolutions of the power output shaft 41 can be obtained.

As in the recording manner provided in the second embodiment, a functional relationship between the number of rotations of the power output shaft 41 and the moving distance of the movable fan 2 may be established in advance, and then the position of the movable fan 2 is calculated according to the detected number of rotations and the established functional relationship, so that when the number of rotations reaches the threshold value of the number of rotations corresponding to the specific position of the movable fan 2, the window machine 4 is controlled to stop operating, so that the movable fan 2 stays at the specific position.

It should be noted that the angle sensor 51 described in the second embodiment and the third embodiment is not limited to the above example, and different types of angle sensors 51 may be used according to actual design requirements, for example: rotary transformers, rotary capacitors, photoelectric encoders, rotary magnetic encoders, rotary inductors, gyroscopes, and the like.

In addition to the detection of the rotation angle and the number of rotations provided in the above embodiment, the position information of the movable fan 2 may be determined according to the operation time of the window machine 4.

Example four.

The present embodiment differs from the above-described embodiment in that the opening degree detection device 5 includes a timer. Wherein the timer is connected with the controller, or the timer is integrated in the controller; the timer may be used to record the rotational time of the window power take-off 41 and send the rotational time to the controller to cause the controller to control the start and stop of the window machine 4 based on the rotational time.

Because the movable fan 2 is acted by gravity, the window machine 4 and the movable fan 2 can be kept in a synchronous motion state, namely, the rotation process of the window machine 4 is synchronous with the movement process of the movable fan 2. The weight of the movable fan 2 is fixed, so that the window machine 4 can basically keep running at a constant speed, and therefore, the moving position of the movable fan 2 and the rotation time of the window machine 4 have a positive correlation functional relation.

The functional relationship between the movement position and the rotation time may be predetermined, thereby determining the time required for the movable fan 2 to move to each opening position. During the moving process of the movable fan 2, the rotation time can be recorded in real time, whether the movable fan 2 moves to the position corresponding to the specific opening degree is judged according to the rotation time, and when the rotation time reaches the time required for moving to the position corresponding to the specific opening degree, a stop instruction is generated to control the window machine 4 to stop running, and the position of the movable fan 2 is locked through the self-locking mechanism 42.

It should be noted that, due to the gravity action of the movable fan 2, the window machine 4 drives the movable fan 2 to move upwards and downwards to have different degrees of acting against the gravity, that is, the gravity is opposite to the traction direction in the moving upwards process of the movable fan 2, and the required traction force is relatively large; while during the downward movement of the movable fan 2, the gravity and the traction force are in the same direction, and the required traction force is relatively small. When the output power of the window machine 4 is kept unchanged, the traction difference will cause a certain difference between the upward movement speed and the downward movement speed of the movable fan 2, so in order to realize more accurate opening adjustment, different required time thresholds can be set for the upward movement process and the downward movement process, and the adaptive time threshold can be selected for judgment according to the actual requirement adjustment process.

For example, when the user sets the window opening to be adjusted from 25% to 50%, it is necessary to control the movable fan 2 to move downward, at which time the time threshold Td25 required to move downward by 25% may be called up and compared with the rotation time T detected by the timer, and when T reaches the time threshold Td25, the window 4 is controlled to stop rotating. Similarly, when the user sets the window opening to be adjusted from 75% to 25%, the time threshold Tu50 required for moving up to 50% of the opening may be adjusted, and compared with the rotation time T detected by the timer, and when T reaches the time threshold Tu50, the window 4 is controlled to stop rotating.

According to the above technical scheme, in the above embodiment, the position information of the movable fan 2 can be indirectly detected by detecting the information such as the rotation angle, the rotation number and the rotation time of the window machine 4, so as to realize the adjustment of the window opening. The indirect detection of the position information can reduce the use of the sensor, reduce the use amount of detection elements on the outer frame 1, the movable fan 2 and the fixed fan 3, facilitate the design and processing of the section bar and reduce the assembly difficulty of the window body.

In some embodiments, the position sensor 52 may be further disposed on the outer frame 1 and/or the movable fan 2 and/or the fixed fan 3, and the position information of the movable fan 2 may be directly detected by the position sensor 52, so that the window machine 4 may be started or stopped according to the position information.

Example five.

As shown in fig. 7, the present embodiment differs from the above-described embodiment in that the opening degree detection device 5 includes a position sensor 52. The position sensor 52 is arranged on the outer frame 1 and/or the movable fan 2, and the position sensor 52 is electrically connected with the window; the position sensor 52 is configured to detect position information of the sash and/or a transmission mechanism in the driving device and to send the position information to the controller;

the controller is configured to: and obtaining a target position corresponding to the target opening, and generating a driving instruction according to the target position and the position information so as to control the driving device to move the window sash to the target position.

The position sensor 52 includes one or more combinations of a micro switch, a travel switch, a photo-electric position sensor, a hall position sensor, and a piezo-electric position sensor. The position sensor 52 may be based on an optical sensor, a magnetic sensor, a piezoelectric sensor, an inductive sensor, an ultrasonic sensor, a cycloidal sensor, or the like. Wherein the optical sensor senses the position information using a photodiode or a laser photodiode. Such as an optical encoder, a laser interferometer, etc. The magnetic sensor may use magnetic material to sense positional information. Such as hall effect sensors, magneto-electric sensors, etc. The piezoelectric sensor may convert the change in position into a charge signal output. Such as piezoelectric ceramic sensors, capacitive sensors, etc. Inductive sensors may use inductance changes to measure position information. Such as inductive linear displacement sensors, transformer type displacement sensors, etc. Ultrasonic sensors may utilize acoustic waves to sense positional information. Such as ultrasonic ranging sensors, etc. The cycloid sensor determines position information by measuring angular changes of the cycloid gear. Such as a cycloidal encoder.

When the opening degree adjustment is performed based on the position information detected by the position sensor 52, any opening degree adjustment and specific opening degree adjustment may be performed according to the type and arrangement of the position sensor 52. For example, for any opening degree adjustment, an optical sensor such as a laser radar or the like formed to cover the entire movable fan 2 may be provided on the casing 1. The optical sensor can directly detect the top section bar position of the movable fan 2 and send the detected position information to the controller, so that the controller can control the window machine 4 to start or stop running according to the user setting and the current position of the movable fan 2, and stop the movable fan 2 at any opening position.

In order to implement a specific opening degree adjustment process, the opening degree detection device 5 may include a plurality of position sensors 52, and the plurality of position sensors 52 may be respectively located in the moving stroke of the window sash to detect opening degree information of the window sash by the plurality of position sensors 52. Wherein, the distance between the position sensors 52 and the top beam of the outer frame 1 is equal to a plurality of preset percentages of the total moving stroke of the movable fan 2.

For example, the opening degree detecting device 5 may include five position sensors 52, where the five position sensors 52 are located at 0%, 25%, 50%, 75%, and 100% positions corresponding to the opening degree of the window, that is, the position sensors 52 may be disposed at the top beam, 25cm from the top beam, 50cm from the top beam, 75cm from the top beam, and on the middle beam of the outer frame 1, respectively, for the entire travel path of 1m of the movable fan 2.

The position sensor 52 may be a proximity sensor such as a hall element, when the top section bar of the movable fan 2 moves to a detection range of any sensor, the position sensor 52 may detect a corresponding proximity signal and send the proximity signal to the controller, and the controller determines the position of the movable fan 2 according to the sensor position where the proximity signal is detected, so as to determine whether the movable fan 2 moves to a set opening, and when determining that the movable fan 2 moves to a position corresponding to the set opening, the controller stops running to implement opening adjustment by controlling the window machine 4.

For example, the five position sensors 52 are a sensor a, a sensor B, a sensor C, a sensor D, and a sensor E in this order from top to bottom in terms of the installation position. When a user inputs an adjustment instruction for adjusting the opening degree to 50% through a remote controller or a control panel, the window machine 4 operates to drive the movable fan 2 to move downwards. When the movable fan 2 moves to the position corresponding to 50% of the opening degree, the sensor C can generate a proximity signal and send the proximity signal to the controller of the window machine 4, the controller acquires the source of the proximity signal, and when the proximity signal is determined to be sent by the sensor C, the movable fan 2 is determined to move to the position corresponding to 50% of the opening degree, so that the window machine 4 can be controlled to stop running, and the movable fan 2 is kept at the position corresponding to 50% of the opening degree.

Obviously, in order to achieve detection of the position of the movable fan 2, the position sensor 52 may be based on different detection principles, and the plurality of position sensors 52 may be a combination of a plurality of types of sensors. For example, the position sensor 52 includes hall elements provided on the columns of the frame 1, and/or infrared correlation gratings provided on the columns of the frame 1. As shown in fig. 8, taking an infrared correlation grating as an example, a plurality of infrared emitters 53 and infrared receivers 54 may be respectively disposed on two side columns of the outer frame 1, and the infrared emitters 53 may emit infrared light to the infrared receivers 54. Then, when the movable fan 2 moves between the infrared emitter 53 and the infrared receiver 54, the infrared light is blocked, so that the infrared receiver 54 cannot receive the infrared light sent by the infrared emitter 53, and the position of the movable fan 2 is detected. Similarly, by providing the positions of the plurality of infrared emitters 53 and the infrared receiver 54 at positions corresponding to the specific opening, it is possible to detect whether the movable fan 2 moves to the specific opening position.
