Description

[Technical Field]

[0001] The present invention relates to a control device that can be installed in an electric vertical blind. [Background technology]

[0002] Conventionally, there has been known an electrically operated vertical blind that can block sunlight by rotatably supporting one louver from each of multiple carriers that are movably mounted along a head rail, and operating the louvers by driving a motor via a control device.

[0003] Meanwhile, a conventional manual vertical blind is known, for example, from the following Patent Document 1. The manual vertical blind shown in this document is configured to rotatably support two louvers suspended at different angles from multiple carriers provided on the head rail, and is advantageous in that the amount of protrusion of the head rail in the front-to-rear direction when the louvers rotate can be made uniform on both the inside and outside of the room.

[0004] There is also a demand for such manual vertical blinds to be configured as electrically operated vertical blinds in which the louvers are operated by driving a motor as described above. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-92103 Summary of the Invention [Problem to be solved by the invention]

[0006] However, there were issues such as the fact that the rotation direction between fully closed and fully open differs depending on the installation orientation of the two louvers, and that the rotation range differs from when there is only one louver suspended from the carrier, making it undesirable to directly use the control device equipped in the above-mentioned conventional electric vertical blinds in manual vertical blinds such as those described in Patent Document 1.

[0007] Therefore, there has been a demand for a control device that can be suitably installed on electric vertical blinds of different models and specifications.

[0008] In view of the above circumstances, an object of the present invention is to provide a control device that can be suitably installed in motorized vertical blinds of different models and specifications. [Means for solving the problem]

[0009] To achieve the above object, one aspect of the present invention provides a control device that can be installed in at least one of a first model in which two louvers are rotatably suspended at different angles from each of a plurality of carriers provided on a head rail, and a second model in which one louver is rotatably suspended from each of the plurality of carriers, and the control device includes a control unit and a switching means. The control unit operates the louvers by driving a motor in cooperation with a rotational position detection means for the rotational axis of the louvers. The switching means can switch at least one setting of the louver's rotational amount and rotation direction.

[0010] According to this configuration, it is possible to provide a control device that can be suitably installed in electrically operated vertical blinds of different models and specifications.

[0011] The control device may be mountable on both the first model and the second model, in which case the switching means may be capable of switching the amount of rotation of the louver that can be set by an operator between a first amount of rotation and a second amount of rotation that is different from the first amount of rotation.

[0012] With this configuration, even if the control device is shared between the first and second models, suitable control is possible by switching the setting of the louver rotation amount. Specifically, it is possible to prevent an increase in power consumption and the generation of operating noise caused by the motor continuing to rotate even when the louver rotation position in the first model has reached its physical limit.

[0013] The first amount of rotation may be approximately 90°, and the second amount of rotation may be approximately 180°.

[0014] According to this configuration, the control device can be preferably used for both a first model in which two louvers are suspended from a carrier and a second general model in which one louver is suspended from a carrier.

[0015] The first model may have an automatic full-closing function that rotates the louvers to a fully closed state after unfolding them along the longitudinal direction of the head rail, in which case the switching means may be capable of switching the rotation direction of the louvers in the automatic full-closing function.

[0016] With this configuration, regardless of the orientation of the two louvers in the first model (that is, regardless of the device specifications), it is possible to prevent the louvers from rotating in an unintended direction when operating with the automatic full-closing function.

[0017] The first type of motorized vertical blind may have a first louver and a second louver, in which case the first louver may be an opaque louver and the second louver may be a translucent louver.

[0018] According to this configuration, openings such as windows can be reliably blocked when the automatic full-closing function of the first model is activated.

[0019] The switching means may be a dip switch.

[0020] According to this configuration, the switching means can be configured with a simple structure.

[0021] A control device according to another aspect of the present invention is a control device that can be installed in at least one model of electric vertical blinds between a first model in which two louvers are rotatably suspended and supported at different angles from each of a plurality of carriers provided on a head rail, and a second model in which one louver is rotatably suspended and supported from each of the plurality of carriers, and the control device includes a memory unit, a receiver unit, a switching unit, and a control unit. The memory unit stores management information in which device information and setting information are associated with each other. The receiver unit receives the device information from a terminal device. The switching unit identifies setting information corresponding to the device information based on the management information and the device information received by the receiver unit, and switches to the setting indicated by the identified setting information. The control unit controls the louvers based on the setting switched by the switching unit. The switching unit is capable of switching at least one setting of the amount of rotation and the direction of rotation of the louvers.

[0022] According to this configuration, the switching means can be configured by software, which means that the settings can be switched by operating a switch or a terminal device such as a mobile terminal, thereby improving convenience for the operator. [Effects of the Invention]

[0023] As described above, according to the present invention, it is possible to provide a control device that can be suitably installed in electric vertical blinds of different models and specifications. However, this effect does not limit the present invention. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0025] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0026] First Embodiment First, a first embodiment of the present invention will be described.

[0027] [Configuration of electric vertical blinds] Fig. 1 is a front view of an electric vertical blind according to this embodiment with its louvers deployed. Fig. 2 is a perspective view of the vicinity of the head rail of the electric vertical blind. Fig. 3 is a rear view of the head rail. Fig. 4 is a schematic cross-sectional view of the head rail from the right side.

[0028] As shown in these figures, the electric vertical blind 100 of this embodiment has a head rail 1 fixed to an opening such as a window frame by a bracket or the like (not shown), a plurality of carriers 2 that can slide the head rail 1 in the longitudinal direction (X direction in each figure), and a first louver 4 and a second louver 5 suspended from each carrier 2 via a suspension member 3.

[0029] That is, two louvers are suspended from each carrier 2. The first louvers 4 and the second louvers 5 are attached to the suspension member 3 so that their edges (long sides) are close to each other and the angle formed between their main surfaces is approximately 90 degrees (for example, 95 degrees in this embodiment).

[0030] The first louver 4 is provided in front of the electric vertical blind 100 (on the room side), and is made of an opaque fabric with light blocking properties, such as a drape fabric.

[0031] The second louver 5 is provided behind (on the outside of) the electric vertical blind 100, and is made of a semi-transparent (see-through) fabric that allows light in, such as lace fabric.

[0032] 2 and 4, the hanging member 3 has a supported portion 31 pivotally supported on the shaft portion 2a of the carrier 2, two hook portions 32 provided at the lower ends of both longitudinal ends of the supported portion 31, and a louver hook 33 hung from the hook portions 32. As described above, the two hook portions 32 are set at an angle such that the included angle between the first louver 4 and the second louver 5 is approximately 90 degrees.

[0033] A bag-shaped storage compartment (not shown) is formed at the upper end of the first louver 4 and the second louver 5, and the first louver 4 and the second louver 5 are suspended by storing the louver hook 33 in the storage compartment.

[0034] As shown in Figure 4, in addition to the above-mentioned multiple carriers 2, a screw rod (opening / closing drive shaft) 21 and a tilt rod (rotation drive shaft) 22 that pass through each carrier 2 are provided within the rail section 11 on the front side (inside the room) of the head rail 1.

[0035] 3 and 4, the housing section 12 on the rear side (outside the room) of the head rail 1 houses an opening / closing motor unit 13 housed in a motor mount 14, a rotation motor unit 15 housed in a motor mount 16, and a control unit 17 as a control device that incorporates a motor drive circuit and control circuit for driving the opening / closing motor unit 13 and the rotation motor unit 15. The control unit 17 may also be provided outside the head rail 1.

[0036] As shown in Fig. 1, an opening / closing gear unit 7 connected to a screw rod 21 and an opening / closing motor unit 13 is provided, for example, at the right end in the longitudinal direction (X direction) of the head rail 1, and a rotary gear unit 8 connected to a tilt rod 22 and a rotary motor unit 15 is provided, for example, at the left end. In other words, the opening / closing gear unit 7 and the rotary gear unit 8 connect across two spaces, the rail section 11 and the storage section 12 of the head rail 1, so that the rotation of the opening / closing motor unit 13 and the rotary motor unit 15 is transmitted to the screw rod 21 and the tilt rod 22.

[0037] The control unit 17 has a dip switch 18 as a switching means that can switch the setting of the rotatable amount and rotation direction (described later) of the first louver 4 and the second louver 5.

[0038] End covers 1a are provided on both side surfaces of the head rail 1, and the end covers 1a are provided with wiring lead-out sections 1b that lead the power cable 9 that supplies power to the control unit 17 to the outside of the storage section 12. A rear cover 1c is provided at the opening on the back of the storage section 12. The wiring lead-out sections 1b allow the power cable 9 to be led out even when the storage section 12 is closed by the rear cover 1c.

[0039] When the control unit 17 drives the opening / closing motor unit 13, the rotation is transmitted to the screw rod 21 via the opening / closing gear unit 7. When the control unit 17 drives the rotation motor unit 15, the rotation is transmitted to the tilt rod 22 via the rotation gear unit 8.

[0040] Of the multiple carriers 2, the carrier 2 at the front (the left end in FIG. 1) is designated as the master carrier (not shown). The master carrier 2 can move within the head rail 1 based on the rotation of the screw rod 21.

[0041] As the master carrier 2 moves, adjacent carriers 2 are pulled by spacer links (not shown) that connect the carriers together, causing the head rail 1 to move in the unfolding direction (unfolded state in Figure 1), or the master carrier 2 pushes adjacent carriers 2 in turn, causing the head rail 1 to move in the folding direction.

[0042] Furthermore, the rotation of the tilt rod 22 is transmitted to the hanging member 3 via the shaft portion 2a of the carrier 2, and the first louver 4 and the second louver 5 suspended from the hanging member 3 can rotate around their longitudinal axes.

[0043] The rotary motor unit 15 has a built-in encoder as detection means for detecting the rotational position of the tilt rod 22, and the encoder is capable of transmitting information about the detected rotational position to the control unit 17. The encoder may be provided in a location other than the rotary motor unit 15, such as the tilt rod 22. Various types of encoders may be used, including mechanical, optical, and magnetic types.

[0044] The state shown in FIG. 1 is a state in which the first louvers 4 and second louvers 5 are fully unfolded, the first louvers 4 being approximately perpendicular to the longitudinal direction (X direction) of the head rail 1, and the second louvers 5 being approximately parallel to the longitudinal direction (X direction). In this embodiment, a state in which the second louvers 5 (which are made of translucent fabric) close an opening in a window frame or the like is defined as a "partially closed" state, and a state in which the first louvers 4 (which are made of opaque fabric) are approximately parallel to the longitudinal direction (X direction) and close the opening is defined as a "fully closed" state. Furthermore, a state in which the first louvers 4 and second louvers 5 form an angle of approximately 45° with the longitudinal direction (X direction) of the head rail 1 (see FIGS. 6(b) and 7(b)) is defined as a "fully open" state.

[0045] The motorized vertical blind 100 is available in a left-opening configuration in which the first louver 4 and the second louver 5 are opened approximately 90 degrees to the left side in a plan view (forming an inverted "L" shape), and a right-opening configuration in which the first louver 4 and the second louver 5 are opened approximately 90 degrees to the right side in a plan view (forming an "L" shape). To achieve the fully closed state after deployment, the left-opening configuration requires the first louver 4 and the second louver 5 to be rotated clockwise in a plan view, while the right-opening configuration requires the first louver 4 and the second louver 5 to be rotated counterclockwise in a plan view. To achieve the semi-fully closed state after deployment, the left-opening configuration requires the first louver 4 and the second louver 5 to be rotated counterclockwise in a plan view, while the right-opening configuration requires the first louver 4 and the second louver 5 to be rotated clockwise in a plan view. These two specifications are used depending on the direction of sunlight entering through the opening, etc.

[0046] Furthermore, the motorized vertical blind 100 in this embodiment is a model (first model: backlace style) in which two louvers (first louver 4 and second louver 5) are suspended and supported so that they can rotate at different angles from each of the multiple carriers 2, as described above. However, there is also a model (second model: single style) in which one louver is rotatably suspended and supported from each of the carriers. The louvers of the first model can rotate by approximately 90°, and the louvers of the second model can rotate by approximately 180°.

[0047] Therefore, if the louvers of the electric vertical blind with the left-opening specification are simply replaced with those with the right-opening specification, the direction of rotation of the louvers will not change, and the fully closed state in the left-opening specification will become the half-fully closed state in the right-opening specification, preventing the user from performing the intended operation.

[0048] Furthermore, since the louvers of the first and second models can rotate by different amounts, if, for example, the louvers (single style) of the second model are simply replaced with the louvers (backlace style) of the first model without changing the rotation setting, the louvers will rotate beyond the original rotation limit of approximately 90° of the first model, and although the hanging member itself will rotate freely, the rotation motor will continue to operate, wasting power and generating unpleasant operating noise.

[0049] Therefore, in this embodiment, the dip switch 18 makes it possible to switch the setting of the rotation direction (clockwise / counterclockwise in plan view) of the first louver 4 and the second louver 5 according to the left-opening specification and the right-opening specification of the electric vertical blind 100, and also makes it possible to switch the setting of the amount of rotation of the louvers according to the first model and the second model of the electric vertical blind.

[0050] [Multi-switch configuration] FIG. 5 is a front view of a multi-switch serving as a terminal device used to remotely operate the motorized vertical blind 100, such as for rotating, opening and closing the same.

[0051] As shown in the figure, the multi-switch 50 has a display unit 51 and various operation buttons such as a folding button 52, an unfolding button 53, a counter-rotation button 54, a rotation button 55, and a preset button 56.

[0052] The folding button 52 is a button for transmitting to the control unit 17 a signal to move the first louver 4 and the second louver 5 in the folding direction.

[0053] The unfolding button 53 is a button for transmitting to the control unit 17 a signal to move the first louver 4 and the second louver 5 in the unfolding direction.

[0054] The counter-rotation button 54 is a button for transmitting to the control unit 17 a signal to rotate the first louver 4 and the second louver 5 counterclockwise in a plan view.

[0055] The rotation button 55 is a button for transmitting to the control unit 17 a signal to rotate the first louver 4 and the second louver 5 clockwise in a plan view.

[0056] The preset button 56 is a button for sending a signal to the control unit 17 to perform a preset operation such as the amount of rotation (angle) of the first louver 4 and the second louver 5 (see FIGS. 8 and 9). When the preset button 56 is pressed, the display unit 51 transitions to a screen on which the amount of rotation (angle) of the first louver 4 and the second louver 5 can be input. By pressing each button on the screen as shown in the figure, the number displayed at the bottom right of each button can be input as desired, thereby specifying the amount of rotation (angle). Alternatively, the display unit 51 may display options for selecting the amount of rotation (angle) in predetermined angle increments, such as 15°, and the angle may be specified by pressing a button on the bottom right of which a number corresponding to each option is displayed.

[0057] [Operation of electric vertical blinds] Next, the operation of the motorized vertical blind 100 configured as above will be described.

[0058] In this embodiment, the control unit 17 has an automatic full-close function that unfolds the first louver 4 and the second louver 5 from a folded state along the longitudinal direction (X direction) of the head rail 1, and then rotates them to the fully closed state. In executing the automatic full-close function, the control unit 17 can switch the rotation direction of the first louver 4 and the second louver 5 using the dip switch 18 depending on whether the motorized vertical blind 100 is a left-opening specification or a right-opening specification.

[0059] FIG. 6 is an operational diagram showing the automatic full-closing function of the left-opening electric vertical blind 100 from the bottom side.

[0060] When the user presses the unfold button 53 of the multi-switch 50 with the first louver 4 and the second louver 5 folded, the control unit 17 automatically executes a series of operations shown in (a) to (c) of the same figure.

[0061] That is, when the deployment button 53 is pressed, the control unit 17 starts the deployment operation of the first louver 4 and the second louver 5 in the direction of the arrows in FIG.

[0062] Next, as shown in Figure 1(b), when the first louver 4 and the second louver 5 are fully deployed to the edge of the opening, they rotate clockwise when viewed from above (counterclockwise when viewed from the bottom of the figure) until they reach the fully closed state as shown in Figure 1(c).

[0063] When the folding button 52 of the multi-switch 50 is pressed from this fully closed state, the control unit 17 automatically performs a series of operations from the state shown in FIG. 1(c) to the state shown in FIG. 1(b) and then to the state shown in FIG. 1(a).

[0064] FIG. 7 is an operational diagram showing the automatic full-closing function of the right-opening electric vertical blind 100 from the bottom side.

[0065] In the right-opening specification, the rotation direction after deployment is opposite to that in the left-opening specification shown in Fig. 6. Therefore, in this embodiment, when changing from the left-opening specification to the right-opening specification, the rotation direction is also switched to the opposite direction from the left-opening specification using the DIP switch 18.

[0066] After the switching, when the user presses the unfold button 53 of the multi-switch 50, the control unit 17 automatically executes the series of operations shown in (a) to (c) of the same figure.

[0067] That is, when the deployment button 53 is pressed, the control unit 17 starts the deployment operation of the first louver 4 and the second louver 5 in the direction of the arrows in FIG.

[0068] Next, as shown in Figure 1(b), when the first louver 4 and the second louver 5 are fully deployed to the edge of the opening, they rotate counterclockwise when viewed from above (clockwise when viewed from the bottom of the figure) until they reach the fully closed state as shown in Figure 1(c).

[0069] When the folding button 52 of the multi-switch 50 is pressed from this fully closed state, the control unit 17 automatically performs a series of operations from the state shown in FIG. 1(c) to the state shown in FIG. 1(b) and then to the state shown in FIG. 1(a).

[0070] Fig. 8 is a bottom view showing the amount of rotation of the louvers of the electric vertical blind 100 according to the first model. Fig. 9 is a bottom view showing the amount of rotation of the louvers of the electric vertical blind according to the second model. Both figures (a) show the fully closed state, and both figures (b) show the half-fully closed state.

[0071] As described above, when the preset button 56 of the multi-switch 50 is pressed and then a numerical value is input, an angle preset operation is performed in which the louver is automatically rotated to the angle of the input numerical value.

[0072] As shown in both figures, the first louvers 4 and second louvers 5 of the first model of powered vertical blind 100 can rotate approximately 90° between a fully closed state and a partially closed state. On the other hand, the louvers 40 of the second model of powered vertical blind can rotate approximately 180°.

[0073] In the second model of Fig. 9, it is necessary to be able to input a numerical value for the angle preset in the range of 0 to 180, but in the first model of Fig. 8 according to this embodiment, if a numerical value greater than 90 is input (for example, if the angle preset setting of the second model is left as is), the rotatable range will be exceeded. Therefore, when the control unit 17 is installed in the first model of electric vertical blind 100 according to this embodiment, the rotatable amount is switched to 90° by the above-mentioned dip switch 18.

[0074] Conversely, when the control unit 17 of the first model of electric vertical blind 100 is installed in the second model of electric vertical blind, the DIP switch 18 is used to switch the amount of rotation to 180°.

[0075] [summary] As described above, according to this embodiment, it is possible to provide a control unit 17 (control device) that can be suitably installed on electric vertical blinds of different models (number of louvers suspended from one carrier) and specifications (mounting direction of louvers).

[0076] Second Embodiment Next, a second embodiment of the present invention will be described. In this embodiment, parts having the same functions as those in the first embodiment are given the same reference numerals.

[0077] In the first embodiment described above, the control unit 17 switches the settings of the rotation direction and the amount of rotation of the louvers using the hardware switch, the DIP switch 18. Instead, in this embodiment, the control unit 17 switches the settings using software.

[0078] Fig. 10 is a functional configuration diagram of the control unit 17 of the electric vertical blind 100 according to this embodiment. Fig. 11 is a diagram showing table data stored in the electric vertical blind 100 according to this embodiment.

[0079] As shown in FIG. 10, in this embodiment, the control unit 17 has a receiving unit 171, a switching unit 172, and a control unit 173 as software functional blocks (programs).

[0080] As shown in FIG. 11, the memory (storage means) of the control unit 17 pre-stores, as management information, table data in which device information regarding the model (first model / second model) and specifications (left-opening specification / right-opening specification) of the electric vertical blind is associated with setting information (amount of rotation and direction of rotation).

[0081] The receiving unit 171 receives device information relating to the model or specifications of the electric vertical blind from the multi-switch 50 serving as a terminal device.

[0082] Based on the management information stored in the memory and the device information received by the receiving unit 171, the switching unit 172 identifies the setting information corresponding to the received device information and switches to the setting indicated by the identified setting information.

[0083] The control unit 173 controls the louvers based on the settings switched by the switching unit 172. The control unit 173 also functions as a drive unit for the opening / closing motor unit 13 and the rotation motor unit 15. The switching unit 172 can switch at least one of the settings of the rotatable amount and the rotation direction of the louvers.

[0084] FIG. 12 is a sequence diagram showing the flow of the setting switching process of the electric vertical blind 100 according to this embodiment.

[0085] As shown in the figure, first, a predetermined mode switching operation (pressing a code consisting of a predetermined number causes the screen to transition) is input on the multi-switch 50 to transition to a screen where device information for the electric vertical blinds can be selected (S101).

[0086] Subsequently, on the selection screen after the transition, a selection operation for device information is performed (S102), and the device information is transmitted from the multi-switch 50 to the control unit 17 (S103).

[0087] Next, the control unit 17 searches the table data based on the device information received from the multi-switch 50, and identifies the setting information corresponding to the device information (S104).

[0088] Then, the control unit 17 switches to the setting indicated by the specified setting information (S105).

[0089] In this way, according to this embodiment, the switching means can be configured by software. That is, the settings can be switched by operating the multi-switch 50, such as a switch, which improves convenience for the operator.

[0090] <Modification> The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit and scope of the present technology.

[0091] [Modification of the rotation direction of the second model] In the above embodiment, the operation of switching the rotation directions of the first louver 4 and the second louver 5 in the first model of electric vertical blind 100 has been described. However, the rotation direction of the louvers may also be switchable in a second model of electric vertical blind in which one louver is suspended from one carrier.

[0092] FIG. 13 is a bottom view showing the rotation direction switching operation of the electric vertical blind according to the second model.

[0093] As shown in the figure, when the user presses the unfold button 53 of the multi-switch 50 with the louver 40 in the folded state, the control unit 17 automatically executes a series of operations shown in (a) to (c) of the figure.

[0094] That is, when the deployment button 53 is pressed, the control unit 17 starts the deployment operation of the louver 40 in the direction of the arrow in FIG.

[0095] Next, as shown in Figure 1(b), when the louver 40 is fully deployed to the edge of the opening, it rotates clockwise when viewed from above (counterclockwise when viewed from the bottom of the figure) until it reaches the fully closed state as shown in Figure 1(c-1).

[0096] On the other hand, by switching the rotation direction from the fully closed direction to the counter-closed direction in advance using the dip switch 18, the valve rotates counterclockwise in plan view (clockwise in bottom view) from the state shown in Figure (b) to the counter-closed state, as shown in Figure (c-2).

[0097] When the folding button 52 of the multi-switch 50 is pressed from this fully closed state / partially fully closed state, the control unit 17 automatically executes a series of operations from the state shown in (c-1) or (c-2) in the same figure to the state shown in (b) in the same figure and then to the state shown in (a) in the same figure.

[0098] In this way, even in the second model of electric vertical blind in which one louver is hung from one carrier, it is possible to switch the rotation direction of the louver 40 depending on the direction of sunlight, etc., thereby improving convenience.

[0099] [Other variations] In the above-described embodiment, the louvers of the first model (electric vertical blind 100) can be rotated by approximately 90°, and the louvers of the second model can be rotated by approximately 180°, but the rotational amount of each model is not limited to this and can be changed as appropriate.

[0100] In the first and second embodiments described above, the first louvers 4 are made of an opaque material and the second louvers 5 are made of a translucent material, but other materials may also be used for each.

[0101] In the above embodiment, an example in which the louvers are deployed to the left and folded to the right has been shown, but the present invention is similarly applicable to cases in which the louvers are deployed to the right and folded to the left.

[0102] In the above-described embodiment, the switching means (DIP switch 18 or switching unit 172) switches the rotation direction of the louvers only when the automatic full-closing function is executed. However, the switching setting of the rotation direction of the louvers may be executed even when the automatic full-closing function is not executed (for example, when the unfolding operation and the full-closing operation are executed separately).

[0103] In the above-described embodiment, the control unit 17 is capable of switching the settings of both the rotation direction and the rotatable amount of the louver. However, the control unit 17 may be capable of switching only one of the rotation direction and the rotatable amount. [Explanation of symbols]
