JP 2004-3251 A

  In the above-mentioned Patent Document 1, it is necessary to keep pressing the open switch or press the open switch many times, such as when the slat is fully opened as a blind. The preparatory operation is convenient because the shutter opens and closes to a position where the slat can be opened as a blind with a single touch, but after the preparatory operation of the shutter, the slat can be opened unless the slat is rotated as a blind. Can not.

  The present invention has been made in view of the above problems, and solves the problem of providing a blind shutter control device capable of reducing an operation burden for opening a slat as a blind and an operation for a preparation operation. It should be a challenge.

A blind shutter control device according to the present invention includes a blind drive unit that rotates a slat constituting a shutter as a blind, a blind opening signal output unit that outputs a signal for changing the blind opening of the slat, and the blind And a blind shutter control device having a blind opening detection means for detecting the blind opening of the slat, wherein the control means is the registered blind opening. Blind registration position rotating means for rotating the slat to one or more blind registration positions based on the output signal of the blind opening signal output means, and the blind opening based on the output signal of the blind opening signal output means A normal mode for opening and closing the slats, The blind registration position rotation means has a signal amount output by the blind opening signal output means for rotating the slat to the blind registration position, so that the slat is at the blind registration position in the normal mode. When the blind opening of the slat acquired by the blind opening detection means is in the closed position, the control means is less than the amount of signal output by the blind opening signal output means for rotation. The rotation mode is executed, and the normal mode is executed when the blind opening degree of the slat acquired by the blind opening degree detection means is other than the closed position .

  In the blind shutter control device of the present invention, the blind registration position rotation means can rotate the slat to the blind registration position which is the registered blind opening based on the signal output from the blind opening signal output means. it can. The blind registration position is a blind opening degree of a slat set and registered in advance. When a signal is output from the blind opening signal output means, the slat rotates to the registered blind registration position, so that the predetermined blind opening can be achieved without adjusting the blind opening.

The blind registration position rotation means can rotate the slat to the blind registration position with a signal amount smaller than the signal amount when the slat is rotated in the normal mode. Therefore, the signal transmission path from the blind opening signal output means to the control unit can be reduced or simplified.
When an operation for opening the slat as a blind is input to the input means when the slat is closed as a blind, the slat is rotated to the blind registration position by the blind registration position rotation means. When the slat is opened as a blind, when an operation for opening the slat as a blind is input to the input means, the slat is opened and closed at the blind opening in the normal mode. As a result, if the user inputs an operation to the input means to open the slat as a blind while the slat is closed, the slat rotates to the blind registration position. Is released. That is, user input operations can be reduced. In the normal mode, the slat is rotated based on the input of the input means until the slat is blinded and reaches a desired blind opening. In this normal mode, even if the slat is rotated according to the input time when the input of the input means is continued, it is rotated by a certain blind opening (<blind opening of the blind registration position) with one input. It may be a thing to let

Said control means used in a blind shutter control device of the present invention, prior Symbol blind opening signal output means includes input means for operation is input to change the blind opening of the slats, the blind registration The position rotation means is configured such that an operation amount input to the input means for rotating the slat to the blind registration position is applied to the input means for rotating the slat to the blind registration position in the normal mode. It is preferable that the operation amount is less than the input amount. Thereby, the blind registration position rotation means can rotate the slat to the blind registration position with an operation amount smaller than the operation amount input to the input means when rotating the slat in the normal mode. Therefore, the operation amount of the user can be reduced. In addition, since the slat is opened at the registered blind position where the predetermined blind opening is registered, the amount of operation when rotating the slat to the desired blind opening of the user in the normal mode after that is small. I'm sorry.

  The blind registration position rotating means used in the blind shutter control device of the present invention is preferably configured such that the drive amount of the blind drive unit is set so as to rotate the slat to the blind registration position.

  The blind shutter control device according to the present invention includes a shutter position detecting unit that detects the position of the shutter in the opening and closing direction of the shutter, and the position of the shutter acquired by the shutter position detecting unit when an operation is input to the input unit. It is preferable to further include a preparation unit that opens and closes the shutter to the target position when the position is not a position. The input of the operation to the input means is for rotating the slat as a blind, but when the shutter is not an appropriate position for rotating the slat as a blind, the shutter is opened and closed to a target position which is an appropriate position. Can be made. As a result, the user simply performs an input operation to rotate the slat as a blind, and the shutter automatically opens and closes to the target position, and then the slat rotates to reduce the user's input operation. Convenience is good.

  The preparation unit used in the blind shutter control device of the present invention preferably includes a shutter target position storage unit that acquires and stores the target position of the shutter from the shutter position detection unit. The preparation means does not need to be set by the user or the like because the shutter target position storage means can acquire the shutter position from which the slat can rotate as a blind from the shutter position detection means. Therefore, it is possible to reduce the setting time of the user or the like.

  The rotation area of the slat as a blind used in the blind shutter control device of the present invention can be rotated from a closed position to a position of the blind opening larger than a right angle, and the blind opening at the blind registration position is less than a right angle. It is preferable that Accordingly, it is difficult to look into the room when there is another person outside the opening of an opening such as a window where the blind shutter control device of the present invention is installed. In addition, in the case of a type in which the blind is opened and closed in the vertical direction, if the blind opening at the blind registration position of the slat is less than a right angle, rain will enter from the gap of the slat even if it is opened as a blind in the rain. It is possible to prevent water droplets adhering to the slats from flowing into the room. Therefore, members such as dripping prevention can be omitted, and costs associated therewith can be suppressed. In addition, it is possible to prevent direct sunlight from entering, and it is possible to control the sudden brightening of the room.

  The blind driving unit used in the blind shutter control device of the present invention has an actuator that rotates using the slat as a blind, and the control means opens the blind of the slat acquired by the blind opening detection means. It is preferable to further include energization determining means for determining whether the actuator needs to be energized according to the degree. Depending on the blind opening, if the slat can be opened and closed without energizing the actuator of the blind drive unit, it can save energy by reducing power consumption by turning off the actuator. Also, the heat generation of the actuator can be prevented. And since the operation sound made during energization is not stopped by energization, noise can be reduced.

  The blind opening signal output means used in the blind shutter control device of the present invention has setting registration means for outputting a signal for setting and registering an arbitrary blind opening of the slat as the blind registration position to the control means. Is preferred. Since the blind registration position can be set at any blind opening, the blind registration position can be changed according to the preference of the user or the situation of the installation location, and a practical blind shutter control device is provided it can.

  The blind opening signal output means used in the blind shutter control device of the present invention has one or a plurality of registered position rotation signal output means for outputting a signal for rotating the slat to the blind registration position to the control means. It is preferable. Thereby, the registration position rotation signal output means corresponding to one or a plurality of blind registration positions is provided, so that the slats can be opened at a blind opening corresponding to each of a plurality of users, for example.

  According to the blind shutter control device of the present invention, when a signal is output from the blind opening signal means, the slat rotates to the blind registration position of the previously registered blind opening, so that the user does not make adjustments. However, the slats can be opened at a certain blind opening.

The blind registration position rotation means can rotate the slat to the blind registration position with a signal amount smaller than the signal amount when the slat is rotated in the normal mode. The signal transmission path can be reduced or simplified.
Further, since the blind opening of the slat can be detected by the blind opening detecting means, if the detected blind opening is the closed position (blind opening = about 0 degrees), the blind registration position rotating means rotates the slat to the blind registered position. Can be moved. If the blind opening is other than 0 degrees, the slat can be set as a blind in the normal mode and adjusted to an arbitrary blind opening. That is, when the slat is not opened as a blind, the slat can be released to some extent without continuing to perform an input operation on the input means in order to open the slat, so that the operation burden on the user can be reduced.

  The blind registration position rotation means rotates the slat to the blind registration position in the normal mode when the operation amount input to the input means of the blind opening signal output means to rotate the slat to the blind registration position in the normal mode. Since it is less than the operation amount, the burden on the user who operates it is reduced. Further, it is possible to reduce the amount of input operation for opening / closing and rotating the slat to the desired blind opening degree of the user in the normal mode after the rotation to the blind registration position.

  Further, according to the preparation means, when the shutter position acquired by the shutter position detection means is not the target position where the slat can be rotated as a blind, the shutter is opened and closed to the target position, and then the slat is moved. Since it opens and closes, the user's input operations are reduced and it is easy to use.

  Furthermore, since the preparation means can automatically acquire and store the position in the opening / closing direction of the shutter from the shutter position detection means without setting the target position by the user, it takes time and effort for the user etc. for setting. Can be reduced.

  And by setting the blind opening at the blind registration position of the slat to be equal to or less than a right angle, the room can be easily opened when there is another person outside the opening of a window or the like where the blind shutter control device of the present invention is installed. Difficult to see through. In addition, in the case of a type in which the blind is opened and closed in the vertical direction, if the blind opening at the blind registration position of the slat is less than a right angle, rain will enter from the gap of the slat even if it is opened as a blind in the rain. It is possible to prevent water droplets adhering to the slats from flowing into the room. Therefore, members such as dripping prevention can be omitted, and costs associated therewith can be suppressed. In addition, it is possible to prevent direct sunlight from entering, and it is possible to control the sudden brightening of the room.

  Further, according to the energization determining means, it is possible to determine whether the actuator of the blind drive unit needs to be energized or not according to the blind opening of the slat acquired by the blind opening detecting means. If the slats can be opened and closed without them, it is possible to save energy by reducing power consumption by turning off the power. Accordingly, the heat generation of the actuator can be prevented, and the operating sound during energization is not stopped by stopping the energization, so noise can be reduced.

  Moreover, since the blind registration position can be set at any blind opening by the setting registration means, the blind registration position can be changed according to the preference of the user or the situation of the installation location, etc. A blind shutter control device can be provided.

  By providing registration position rotation signal output means corresponding to one or a plurality of blind registration positions, for example, the blind opening corresponding to each of a plurality of users or the blind opening depending on the time zone or outdoor weather conditions, etc. By changing and registering, you can open slats to each.

  Hereinafter, the present invention will be specifically described with reference to examples.

Example 1
The blind shutter control device of this embodiment is applied to an electric shutter device 10 that opens and closes an opening of a structure. FIG. 1 is a view of an electric shutter device 10 applied to an opening such as a window as viewed from the indoor side. As shown in FIG. 1, the electric shutter device 10 includes a motor 11, a take-up shaft 12 that is rotationally driven by the motor 11, two guide rail portions 15 that run in parallel extending in the vertical direction, and a guide rail. A shutter curtain (shutter) 13 that is moved up and down along the portion 15 to open and close the opening as it is raised and lowered, and a storage box 16 that stores the motor 11 and the winding shaft 12 are provided. In addition, the motor 11 comprises a blind drive part (drive part) with the actuator 50 mentioned later. The blind shutter control device of this embodiment is built in, for example, the storage box 16.

  First, the mechanism of opening and closing the shutter curtain 13 and the opening and closing of the blind of the electric shutter device 10 controlled by the blind shutter control device of this embodiment will be described.

  The motor 11 can rotate the shutter curtain 13 in the winding direction and the rewinding direction, respectively. Therefore, the winding shaft 12 rotated by the motor 11 can rotate the shutter curtain 13 in the winding direction (arrow Y1 direction) and the rewinding direction (arrow Y2 direction). That is, as the motor 11 rotates in one direction, the shutter curtain 13 is wound around the winding shaft 12 and is lifted (opened). Due to the rotation of the motor 11 in the other direction, the shutter curtain 13 is unwound from the take-up shaft 12 and is drawn out (closed). The motor 11 is operated by a controller (blind open signal output means, input means) 300 described later.

  A motor operation detector 111 such as a rotary encoder is provided on the motor shaft of the motor 11. When the motor 11 is driven and the shutter curtain 13 is driven in the closing direction or the opening direction, a signal output from the motor operation detector 111 such as an encoder is input to the control unit 100 described later. The shutter position detection means written in the memory 104 of the control unit 100 is based on the signal of the motor operation detector 111 such as an encoder, and the rotation amount of the motor 11, the rotation speed of the motor 11, and the current lower end of the shutter curtain 13. The position can be detected, and it is thereby possible to detect whether or not the lower end of the shutter curtain 13 has reached the fully closed position or the fully open position. The detected position is stored in the memory 103 of the control unit 100 each time.

  The shutter curtain 13 includes a seat plate 17 that forms the lower end and a large number of slats 18 that form a portion above the seat plate 17. The slats 18 are extended horizontally, and a plurality of the slats 18 are arranged in parallel along the vertical direction. The slat 18 can be switched between a shutter usage form in which the slat 18 is used as a shutter curtain and a blind usage form in which the slat 18 is used as a blind.

  As shown in FIG. 2, a connecting shaft portion 19 that extends outward in the lateral direction of each slat 18 and reaches the guide rail portion 15 is integrally connected to the slat 18. A link 21 is fixed to a distal end portion of the connecting shaft portion 19 by a screw 20x as a fixture so that the slat 18 can be rotated. A connecting pin 22 is planted at the upper end of the link 21. The connecting pin 22 is rotatably fitted in a long hole 23 formed in the lower end portion of the link 21 located immediately above the connecting pin 22. A pin 25 implanted in a bracket 24 fixed to the seat plate 17 is fitted into the long hole 23 of the link 21 of the lowermost slat 18 among the plurality of slats 18. At the end of each slat 18, a pivot shaft 26 is provided as a locking body that is positioned above the connecting shaft portion 19 and extends laterally outward. In FIGS. 2 to 6, the number of slats 18 is shown smaller than the actual number in order to avoid complication of the drawings.

  As shown in FIG. 2, a guide portion 30 having a circular cross section extends long along the vertical direction on the inner end surface of the guide rail portion 15. The guide portion 30 is integrally formed with the guide rail portion 15 via the rib 31. A base end portion of the switching member 33 having a substantially L-shaped cross section extends in the vertical direction along the guide portion 30 and is rotatable about the guide portion 30. At the tip of the switching member 33, a plurality of cutouts 34 are formed at an equal pitch with an interval in the vertical direction. The cutout 34 is formed so as to be directed to the outdoor side and open obliquely downward.

  An upper end portion of a cam body 36 is pivotally attached to the guide rail portion 15 via a pin 35. The lower end portion of the cam body 36 is in contact with the proximal end portion side of the switching member 33. Note that a spring (not shown) urges the switching member 33 in the indoor direction. Thereby, this contact is always maintained. A capturing member 40 is pivotally attached to a central region of the cam body 36 by a pin 38 so as to be rotatable. The capture member 40 is pivotally attached to the guide rail portion 15. The capturing member 40 is formed with a slot 42 as a locked portion having a tip opening. A front end portion of the opening of the slot 42 is an engaging portion 40a. The capture member 40 has a cam groove 43 formed above the slot 42.

  In the vicinity of the capture member 40, an actuator 50 of a blind drive unit is disposed. The actuator 50 has a plunger 51 that can move up and down. A pin 52 is implanted at the tip of the plunger 51. The tip of the pin 52 is slidably inserted into the cam groove 43 of the capturing member 40. When the actuator 50 is set to the first position where the actuator 50 is not operated (shutter usage pattern), the stroke of the plunger 51 is maximum. That is, the protrusion amount of the plunger 51 from the main body is the maximum. On the other hand, when the actuator 50 is operated and switched to the second position (blind usage mode), the plunger 51 is drawn into the body of the actuator 50. Thereafter, by driving the motor 11, the winding shaft 12 rotates in the winding direction, and the shutter curtain 13 rises in the arrow Y1 direction and moves in the opening direction.

  At this time, the capturing member 40 rotates about a pin 41 in the illustrated counterclockwise direction (in the direction of arrow B1 in FIG. 3, the blind use direction) by a predetermined angle (for example, about 25 degrees). When the capture member 40 rotates about the pin 41 as described above, the engaging portion 40a of the capture member 40 is displaced in the direction of arrow B1 (blind use direction) as shown in FIG. It is switched to the up-and-down movement trajectory of the unit 19 (blind usage pattern). Therefore, as shown in FIG. 4, the connecting shaft portion 19 of the slat 18 directly below the slat 18 rising in the direction of the arrow Y <b> 1 as the winding shaft 12 rotates rotates from the lower side of the capturing member 40. Engage with the engaging portion 40a. As a result, as the winding shaft 12 rotates, the slat 18 directly below continues to rise, so that the connecting shaft portion 19 of the slat 18 pushes up the engaging portion 40a of the capturing member 40 as shown in FIG. . Accordingly, the capturing member 40 further rotates by a predetermined angle in the counterclockwise direction (arrow B1 direction, blind use direction).

  When the capture member 40 rotates in the direction of the arrow B1 about the pin 41 in this way, the cam body 36 is pressed by the cam groove 43 of the capture member 40, and as a result, the cam body 36 is opposite to the pin 35 by a predetermined angle. It turns clockwise (arrow B1 direction, blind use direction). As a result, as shown in FIG. 5, the connecting shaft portion 19 of the slat 18 immediately below the slat 18 that is closest to the capturing member 40 enters the slot 42 of the capturing member 40. In addition, the pivot shaft 26 that is a locking body of the subsequent slat 18 enters into the depth of the notch 34 of the switching member 33.

  Here, since the driving of the motor 11 is continued and the winding shaft 12 continues to rotate in the winding direction, the shutter curtain 13 does not rise in the arrow Y1 direction. Then, as shown in FIG. 6, the pivot shaft 26 of the slat 18 is restrained by the notch portion 34 of the switching member 33 and cannot be further raised. In this state, the winding shaft 12 is rotated in the winding direction by the motor 11 in a state where the turning shaft 26 is constrained by the notch portion 34, so that the connecting shaft portion 19 of the slat 18 does not rise. The slat 18 rotates in the direction of the arrow M1 (see FIG. 6, blind opening direction) about the rotation shaft 26 as a rotation center. By adjusting the amount of increase, the blind opening (rotation angle) of the slat 18 can be adjusted.

  The blind opening indicating how much the slat 18 is opened from the closed position is obtained by the blind opening detecting means written in the memory 104 of the control unit 100. The blind opening degree detection means calculates from the rotation amount of the motor 11, the rotation speed of the motor 11, and the like based on the signal transmitted from the motor operation detector 111 provided on the motor shaft of the motor 11 to the control unit 100. Thus, it is possible to detect whether the slat 18 has reached the closed position or the fully opened position.

  To open / close the shutter curtain 13 and open / close the slat 18 as a blind, an operation is input to the controller 300 of the blind shutter control device. As shown in FIG. 7, the operation switch of the controller 300 includes a shutter open switch 301 that instructs to raise the shutter curtain 13, a shutter close switch 302 that instructs to lower the shutter curtain 13, and the shutter curtain 13. There are a shutter stop switch 303 for stopping the raising or lowering of the shutter, a blind opening switch 304 for opening and turning the slat 18 as a blind, and a blind closing switch 305 for closing and turning the slat 18 as a blind. Then, the controller 300 operates (ON) each switch and outputs a signal corresponding to each switch to the control unit 100. Therefore, the controller 300 functions as a blind open signal output means (open signal output means) and as an input means.

  The signal output from the controller 300 is input to the control unit (control means) 100 as shown in FIG. As shown in FIG. 3, the blind shutter control device of the present embodiment cannot write data that stores a control unit 100 that controls driving of the motor 11, a memory 103 (such as EPROM) that can be written as a storage unit, and a program. And a memory 104 (ROM or the like).

  The memory 104 that cannot be written to by the control unit 100 includes a blind opening adjustment unit (normal mode), a blind registration position rotation unit, a preparation unit, an energization determination unit, a shutter position detection unit, and a blind opening detection unit. Is written in advance.

  The blind opening adjusting means controls the motor 11 and the actuator 50 based on the signal output from the controller 300, and opens and closes the slat 18 so that the blind opening desired by the user is obtained. In the blind opening adjusting means, if the blind opening switch 304 or the blind closing switch 305 of the controller 300 is continuously pressed, the slat 18 is opened and closed while the button is kept pressed. Alternatively, when the switch is operated once, it rotates about a certain degree of blind opening, for example about 10 degrees, 20 degrees, 30 degrees or 90 degrees, 80 degrees, 70 degrees and so on. The fixed blind opening for rotation is not limited to 10 degrees, and may be any angle such as 1 degree, 5 degrees, 15 degrees, and 20 degrees.

  The blind registration position rotating means is a means for opening the slat 18 when the slat 18 is registered from the closed position, for example, when the blind opening is about 70 degrees. When the blind opening switch 304 of the controller 300 is turned on while the slat 18 is closed, the blind registration position rotating means operates. Here, the blind opening as the blind registration position is within 90 degrees where rain does not enter when the slat 18 is opened, and is sufficiently larger than the blind opening when the slat 18 is opened with the conventional blind opening switch. . For example, about 20 degrees (25 degrees, 30 degrees, etc.) <Blind opening at blind registration position <about 90 degrees. In addition, the blind registration position is an angle at which direct sunlight does not enter the room when the slat 18 is opened, or an angle at which the room cannot be easily viewed by others outside the room.

  When the blind opening switch 304 of the controller 300 is turned on, the preparation means moves the shutter curtain 13 to the target position when the shutter curtain 13 is not the target position of the shutter curtain 13 that can rotate with the slat 18 as a blind. It is means for driving in the opening direction or the closing direction. As the position of the lower end of the seat plate 17 of the electric shutter device 10 used in this embodiment, the state where the lower end of the seat plate 17 has landed is the landing position, the lower end of the seat plate 17 has landed, and the slats 18 are in the vertical direction. The state in which the shutter curtain 13 is driven in the closing direction until the gap disappears is the fully closed position, and the state in which the slat 18 immediately above the seat plate 17 is stored in the storage box 16 is the fully open position. Here, as the target position, a state is shown in which the shutter curtain 13 is driven in the closing direction (arrow Y2 direction) by one seat plate 17 from the fully open position to the up and down direction of the slat 18 from the landing position. In the fully closed position, safety measures are taken to prevent the slat 18 from being opened as a blind for security reasons.

  The preparation means includes shutter target position storage means for automatically calculating the target position and storing the calculated target position. When the electric shutter device 10 is installed, the shutter target position storage means automatically calculates the target position from the position information when the landing position, the fully closed position, and the fully open position of the shutter curtain 13 are determined. In other words, the electric shutter device 10 is automatically calculated according to the state where the electric shutter device 10 is installed in the opening by the user or the contractor, and is written in the memory 103 of the control unit 100. Therefore, the preparation means reads this target position from the memory 103 and opens or closes the shutter curtain 13 to the target position.

  The energization determining means is a means for determining whether or not the actuator 50 is energized when the slat 18 is opened and closed. As described above, the slat 18 is opened and closed by driving the actuator 50 and the motor 11. Depending on the blind opening of the slat 18, the shutter 11 is raised or lowered by the motor 11 without driving the actuator 50. The slat 18 can rotate. Therefore, if the slat 18 can be opened and closed without energizing the actuator 50, it is possible to save energy by turning off the energization, and noise accompanying driving of the actuator 50 can be reduced.

  FIG. 9 shows a flowchart of a subroutine executed by the control unit 100 of the blind shutter control device of this embodiment when the slat 18 is opened as a blind. This flowchart is not limited to that shown in FIG. 9, but is merely an example. In FIG. 9, it waits for the blind opening switch 304 of the controller 300 to be operated (ON) in order to open the slat 18 as a blind (step S401 and step S402). When the blind opening switch 304 is turned on, first, the position of the shutter curtain 13 is acquired from the shutter position detecting means (step S403), and whether or not the shutter curtain 13 is raised to a target position where the slat 18 can be opened as a blind. Is determined (step S404). If the shutter curtain 13 is not at the target position, preparation means for raising the shutter curtain 13 to the target position is executed (step S405). If the shutter curtain 13 has reached the target position, the blind opening of the slat 18 is acquired from the blind opening detection means (step S406). And it is determined whether the acquired blind opening is a closed position (blind opening = about 0 degree | times) (step S407). If the slat 18 is in the closed position, the process proceeds to a blind registration position rotating means for opening the slat 18 to the blind registration position at one time (step S408). If the slat 18 is not in the closed position, the blind opening of the slat 18 is increased. The process proceeds to a blind opening adjusting means for making a desired blind opening while performing fine adjustment (step S409).

  As a representative control of the blind registration position rotating means in step S408 described above, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 10, but is merely an example. First, the blind registration position rotation means acquires the blind registration position from the memory 103 of the control unit 100 (step S501). Then, a blind opening operation for opening the slat 18 is executed (step S502), and the current blind opening of the slat 18 is acquired from the blind opening detection means (step S503). It is determined whether or not the current blind opening of the slat 18 is the blind registration position (step S504). If the blind opening is not the blind registration position, the process returns to the blind opening operation of step S502. If the current blind opening of the slat 18 is the blind registration position, the blind registration position rotating means is terminated.

  As a typical control of the blind opening operation in step S504 described above, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 11, but is merely an example. In the blind opening operation, first, an energization determining unit that determines whether the actuator 50 needs to be energized to rotate the slat 18 to open is executed (step S601). Then, a motor opening operation for rotating the motor 11 in the winding direction is executed (S602), and the shutter curtain 13 is raised.

  As a representative control of the energization determining means in step S602 described above, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 12, but is merely an example. The energization determining means acquires the current blind opening degree of the slat 18 from the blind opening degree detecting means (step S801). Then, it is determined whether or not the current blind opening needs to energize the actuator 50 (step S802). If the actuator 50 does not need to be energized, the actuator 50 is not energized. If the energization is necessary, the actuator 50 is energized and the operation returns to the blind opening operation.

  As a representative control of the blind opening degree adjusting means in step S409 described above, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 13, but is merely an example. The blind opening adjusting means waits for the blind opening switch 304 of the controller 300 to be turned on in order to open the slat 18 as a blind (steps S701 and S702). When the blind opening switch 304 is turned ON, the current blind opening degree of the slat 18 is acquired from the blind opening degree detecting means (step S703), and the slat 18 is in the fully open position (for example, blind opening degree = about 110 degrees). It is determined whether or not (step S704). If the blind opening of the slat 18 is fully open in step S704, the process returns to the standby of step S701 and waits for the next operation to be input to the controller 300. If the blind opening of the slat 18 is not fully open, a blind opening operation is executed (step S705), and the process returns to the standby of step S701.

  If a switch other than the blind open switch 304 of the controller 300 is turned on in step S702, it is determined whether the blind close switch 305 of the controller 300 is turned on (step S706). When the blind closing switch 305 is turned on, the current blind opening of the slat 18 is acquired from the blind opening detection means (step S707), and is the slat 18 in the closed position (blind opening = about 0 degree)? It is determined whether or not (step S708). If the state of the slat 18 is not the closed position, a blind closing operation is executed to close the slat 18 (step S709), and the process returns to the standby of step S701. When the slat 18 is in the closed position, the blind opening adjustment means is terminated. If the blind closing switch 305 is not turned on in the determination of the blind closing switch 305 in step S706, it is determined whether another operation is input to the controller 300 (step S710). If another operation is input to the controller 300, the blind opening degree adjusting means is terminated, and if not, the process returns to the standby in step S701.

  As a representative control of the blind closing operation in step S709 described above, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 14, but is merely an example. In the blind closing operation, first, an energization determining means for determining whether the actuator 50 needs to be energized in order to close and rotate the slat 18 is executed (step S603). Then, the motor 11 is driven in the rewinding direction (S604), and the shutter curtain 13 is lowered.

  Here, an input operation to the controller 300 will be described. When the blind opening switch 304 of the controller 300 is turned on while the slat 18 is in the closed position, the slat 18 opens to the blind registration position (for example, 70 degrees), but the user turns on each switch of the controller 300 in the middle of opening. It is possible. In the flowchart of this embodiment, no interruption is accepted until the slat 18 reaches the blind registration position. However, a control for accepting an interrupt and stopping the opening of the slat 18 is also conceivable. Alternatively, when the blind opening switch 304 is turned on while the blind registration position is open, control can be performed to stop at another specific blind opening other than the blind registration position.

  According to the blind shutter control device of the present embodiment, when the blind opening switch 304 of the controller 300 is turned on when the slat 18 is in the closed position, the blind registration position rotating means turns the slat into the blind registration position (about 70 degrees). ) Can be rotated at once. That is, the amount of operation by the user is smaller than when the slat 18 is opened by the blind opening adjusting means. Even if the user keeps pressing the blind opening switch 304, the output signal sent from the controller 300 to the control unit 100 is only a signal for opening the slat 18 at 70 degrees, and the signal amount can be reduced. In addition, power consumption can be reduced.

  Further, according to the preparation means, when the position of the shutter curtain 13 acquired by the shutter position detection means is not the target position that can be opened and closed with the slat 18 as a blind, the shutter curtain 13 is opened and closed to the target position. Can be moved. Then, after the shutter curtain 13 is opened to the target position, the slat 18 is opened and rotated, so that the slat 18 is opened by a single input operation, and the user's input operation is reduced.

  The target position is automatically calculated by the shutter target position storage unit according to the situation such as the place where the electric shutter device 10 is installed, and the calculated position can be stored as the target position. That is, when the user or the contractor installs the electric shutter device 10, it is not necessary to set a target position and an appropriate target position is automatically calculated, so that setting effort can be reduced. The target position includes a predetermined range and is not limited to one point.

  By setting the blind opening of the blind registration position of the slat 18 to a right angle or less, when the slat 18 is opened as a blind when it rains, rain enters from the gap of the slat 18 and water droplets attached to the slat 18 are contained in the chamber. It can be prevented from flowing inward, and members such as rain dripping prevention can be omitted, and costs associated therewith can be reduced. In addition, it is possible to prevent direct sunlight from entering or the outside of the room from being easily peeped into the room.

(Example 2)
Example 2 of the present invention will be specifically described. The present embodiment basically has the same configuration and the same function and effect as the first embodiment. The following description will focus on the different parts.

  In the blind shutter control device of the present embodiment, a user registration switch 306 is added to the controller 300 as shown in FIG. This user registration switch 306 is a switch that can register the blind registration position of the slat 18 at a blind opening of the user's preference apart from 70 degrees and rotates the slat 18 to the blind opening. Functions as registration means and registration position rotation signal output means. For convenience, the blind registration position that is the user's favorite blind opening is assumed to be the user registration position (blind registration position).

  When the user registration switch 306 is operated (ON), the controller 300 outputs a signal for rotating the slat 18 to a user registration position, for example, 45 degrees, to the control unit 100. And in order to register a user's favorite blind opening in a user registration position, the user registration switch 306 is long pressed. The controller 300 outputs to the control unit 100 a signal for setting and registering the blind opening when the user registration switch 306 is pressed for a long time as the user registration position. In the control unit 100, the user registration position in the memory 103 is updated to the current blind opening. The timing for detecting the blind opening to be registered is the opening when the slat 18 is stopped, and when the slat 18 is rotating, the slat 18 is rotated at the moment it is pushed. Is the degree of opening.

  FIG. 16 is a flowchart in which the case where the user registration switch 306 is turned on is added to the flowchart of the subroutine executed by the control unit 100 to open the slat 18 shown in FIG. 9 of the first embodiment as a blind. This flowchart is not limited to that shown in FIG. 16, but is merely an example. In FIG. 16, the flow when it is determined that the blind opening switch 304 in step S <b> 402 is turned on is the same as that in the first embodiment, and thus the description thereof is omitted. If it is determined in step S402 that the blind open switch 304 is not turned on, it is determined whether or not the user registration switch 306 is turned on (step S410). If the user registration switch 306 is not turned on, the process returns to step S401 and waits for the blind open switch 304 and the user registration switch 306 to be turned on or another switch to be turned on. If the user registration switch 306 is turned on, it is determined whether or not the switch 306 has been pressed long (step S411). When the user registration switch 306 is pressed for a long time, the blind opening at that time is acquired by executing the blind opening detecting means (step S412), and the user registration position is updated to the blind opening (step S413). . If the user registration switch 306 is turned on instead of being pressed, the position of the shutter curtain 13 is acquired (step S414), and it is determined whether the position is a target position where the slat 18 can be opened as a blind (step S415). If the shutter curtain 13 is not at the target position, preparation means for driving to the target position is executed (step S416), and if it is the target position, the blind registration turning means at step S408 is executed.

  As a representative control of the blind registration position rotating means in step S408, a flowchart is shown in FIG. This flowchart is not limited to that shown in FIG. 17, but is merely an example. The blind registration position rotating means first acquires the blind registration position (user registration position) from the memory 103 of the control unit 100 (step S505). Whether the blind registration position is 70 degrees or the user's favorite 45 degrees is distinguished when the blind registration position rotating means is executed in the flowchart. Next, the current blind opening degree of the slat 18 is acquired by the blind opening degree detecting means (step S506). Then, it is determined whether or not the current blind opening is the blind registration position (step S507). If the blind registration position is the blind registration position, the blind registration position rotating means is terminated. The degree is compared (step S508). If the current blind opening is narrower than the blind registration position, a blind opening operation is executed (step S509), and if it is wider, a blind closing operation is executed (step S510).

  According to the blind shutter control device of the second embodiment, the blind opening position of the user is registered in addition to the blind registration position being initially set to 70 degrees, and the slat 18 is rotated to the blind opening position. can do.

  As shown in FIG. 15, the controller 300 rotates and registers the slat 18 at the user registration position with one switch, but a switch as a setting registration unit may be provided for setting registration. it can. Further, the number of user registration positions is not limited to one, that is, a plurality of blind opening positions other than the initially set 70 degrees may be set and registered as blind registration positions, and the slat 18 may be rotated to the opening positions. You can add as many switches as you can. The blind registration position is set and registered by operating the user registration signal output means while the slat 18 is stopped or rotating, and outputting a signal to the control unit 100. When pressed during the rotation, the rotation of the slat 18 may or may not be stopped. The blind opening degree at the time of being pushed is acquired by the blind opening degree detecting means.

Example 3 of the present invention will be specifically described. The present embodiment basically has the same configuration and the same function and effect as the first or second embodiment. The following description will focus on the different parts.

  The blind shutter control device of this embodiment includes a controller 300 and a room entry detection sensor (not shown). The entrance detection sensor is installed at a place where it can detect that a person has entered the room where the electric shutter device 10 is installed, detects that a person has entered the room, and outputs a signal to the control unit 100, so that the blind is opened. It functions as a signal output means. When a signal is output from the entrance detection sensor to the control unit 100, the blind shutter control device moves to the blind registration position (for example, 70 degrees) as in the case where the blind opening switch 304 is turned on if the slat 18 is in the closed position. The slat 18 is opened and rotated. It is possible to reduce the trouble of operating the controller 300 by detecting the entrance of a person by the entrance detection sensor and opening the slat 18.
