[0008] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the term "visibility direction" refers to the face direction of a shoji screen in a fitting placed in an opening formed in a building, and the term "front view direction" refers to the thickness direction of the shoji screen. In addition, in the drawings of this specification, the "outdoor side" is designated as X1, and the "indoor side" is designated as X2. In this specification, in the shutter device 1, the surface located on the X1 side is defined as the outdoor side visibility surface, and the surface located on the X2 side is defined as the indoor side visibility surface.

[0009] As shown in Fig. 1, the shutter system S of this embodiment includes a shutter device 1 and a wireless receiver 11. The shutter system S is an opening / closing system for opening and closing the shutter device 1, which is an opening / closing device.

[0010] As shown in Figure 1, the shutter device 1 is attached to the exterior wall surface 22 on the outdoor side of a substantially rectangular sliding window 9 housed in an opening 21 of a building skeleton 2. The shutter device 1 is a device that opens and closes the opening 21 by means of a shutter curtain 44 that is rolled up and housed in a shutter box 4, and the shutter device 1 is an opening and closing device for the opening 21. The shutter curtain 44 is also an opening and closing member of the opening and closing device.

[0011] The shutter curtain 44 is configured by connecting multiple slats so that they can rotate freely, but the opening and closing member used in the present disclosure is not limited to this. Anything that can open and close the opening 21 may be used, for example, a seamless screen made of a single piece of fabric. Furthermore, the sizes of the opening and closing member (shutter curtain 44) and the opening 21 are not limited to those in this embodiment. The opening 21 of the present disclosure can be formed in any size, and the opening and closing member can also be configured in any size to match it.

[0012] As shown in Figures 3 and 4, the sliding window 9 of this embodiment has a window frame 91 that fits into the opening 21, and two shoji screens 911, 911 that are slidable left and right inside the window frame 91. The window frame 91 is composed of an upper frame 91a, a lower frame 91b, and vertical frames 91c, 91d arranged left and right, which are framed in a generally rectangular shape. The sliding window 9 may be a French window or a waist-high window, and there are no restrictions on its height in the vertical direction. Furthermore, the type of window used in this disclosure is not limited to the sliding window 9. Any type of window may be provided as long as it is configured to leave an opening inside the window frame 91, and may be, for example, a folding window that can be slid left and right.

[0013] As shown in Figures 2 and 3, an exterior material 23 is provided on the surface of an outer wall surface 22 of a building skeleton 2. The shutter device 1 has a substantially rectangular shutter frame 3, a shutter box 4 attached to the upper part of the shutter frame 3, a pair of guide rails 5, 5, a shutter curtain 44, an opening / closing drive device 45 that drives the winding and unwinding operation of the shutter curtain 44, a battery 6 and a control device 8 housed in a battery case 61, a USB port 7, and a power generation device 10. Note that two shoji screens 911, 911, the opening / closing drive device 45, the USB port 7, and the shutter curtain 44 are omitted in Figure 2. The shutter device 1 can be remotely controlled by a wireless receiver 11 shown in Figure 3.

[0014] The shutter frame 3 is formed by framing an upper frame 31, a lower frame 32, and a pair of left and right vertical frames 33, 33 in a generally rectangular shape. A middle frame 34 spanning the left and right vertical frames 33, 33 is provided slightly below the upper frame 31 and parallel to the upper frame 31 and lower frame 32. The shutter frame 3 is formed of a shaped member obtained by extruding a metal such as aluminum, but is not limited to this. As shown in FIG. 2, the shutter box 4 is a horizontally long box-shaped housing composed of a box main body 41 and a cover member 42 that covers the X1 side of the box main body 41. An opening / closing drive device 45 is housed inside the shutter box 4. The cover member 42 has an outer surface 421 that is the X1 side facing surface.

[0015] As shown in Fig. 3, a shutter curtain 44 wound up in a roll is housed inside the shutter box 4. The shutter curtain 44 has a baseboard 441 extending in the longitudinal direction at the bottom. Both sides of the shutter curtain 44 pulled out from the shutter box 4 are engaged with guide rails 5, 5 attached to the vertical frames 33, 33 of the shutter frame 3, respectively. The shutter curtain 44 is guided by the guide rails 5, 5 to smoothly open and close in the vertical direction. In Fig. 3, the baseboard 441 moved upward by the opening operation and the shutter curtain 44 wound up in a roll are indicated by two-dot chain lines.

[0016] The method of storing the shutter curtain 44 of the present disclosure is not limited to being wound up in a roll. For example, the shutter curtain 44 may be slid in the X2 direction from the shutter box 4 and stored in a storage section provided in the building skeleton 2, instead of being stored inside the shutter box 4. In that case, the shutter curtain 44 may be stored flat in the storage section, rather than being wound up in a roll.

[0017] As shown in Fig. 4, the guide rails 5, 5 are formed into a rectangular tube shape by a front portion 51, a back portion 52, an inner peripheral surface portion 53, and an outer peripheral surface portion 54. The guide rails 5, 5 are made of a shaped member obtained by extruding a metal such as aluminum, but are not limited to this. As shown in Figs. 3 and 4, a battery 6 is attached to the back portion 52 of the guide rail 5. The battery 6 supplies power to an opening / closing drive device 45 housed in the shutter box 4, driving the shutter curtain 44 to open and close. The opening / closing drive device 45 is made up of a winding shaft of the shutter curtain 44, a motor that drives the winding shaft, and the like (not shown).

[0018] The battery 6 is installed in a position accessible from the X2 side through the sliding window 9, allowing anyone to easily replace the battery 6. As shown in FIG. 3, the battery 6 is housed inside a battery case 61 and fixed to the back surface 52 of the guide rail 5 with screws. Alternatively, a cutout may be provided in part of the guide rail 5, and part of the battery case 61 may be inserted into the cutout to securely fix the battery 6.

[0019] The mounting position of the battery 6 of the present disclosure is not limited to the guide rail 5. As long as it is a location that is easily accessible from the sliding window 9, the battery 6 can also be mounted on the inner peripheral surface of the vertical frame 33, for example. Furthermore, the battery 6 may be provided on either the left or right side of the pair of guide rails 5, 5 and vertical frames 33, 33. This configuration eliminates the need for a contractor to disassemble the shutter device 1 and remove the battery from inside the shutter device 1. Furthermore, since a power supply unit that requires wiring is not required, wiring work by a professional is also not required. This allows anyone to easily install or replace the battery 6, and therefore allows the user to instantly replace the battery 6, for example.

[0020] The USB port 7 is a connection part for connecting an external device such as a portable battery. With this configuration, even in an emergency when the battery 6 cannot be used, by connecting an external device such as a portable battery to the USB port 7, power can be supplied from the external device such as a portable battery to the opening / closing drive device 45, and the shutter curtain 44 can be driven to open and close.

[0021] 3 and 5, the USB port 7 can be provided on the battery case 61 like USB port 7A, or on the guide rail 5 like USB port 7B. The location of the USB port 7 is not limited to this embodiment and may be anywhere accessible from the X2 side. For example, the USB port 7 can be provided on the vertical frames 91c and 91d of the window frame 91 that houses the sliding window 9. The connection portion (USB port 7) of the present disclosure is not limited to a USB port as long as it is a portion for connecting to an external device. For example, a DC (direct current) port may be used, and a corresponding connection port can be provided depending on the external device to be connected.

[0022] The control device 8 is housed inside the battery case 61 together with the battery 6, but the installation location of the control device 8 of the present disclosure is not limited to this. For example, the control device 8 may be housed inside the shutter box 4. When an external device such as a portable battery is connected to the opening / closing drive device 45 via the USB port 7, the control device 8 can control so that power is supplied to the opening / closing drive device 45 from the external device, and when the external device such as a portable battery is not connected to the opening / closing drive device 45 via the USB port 7, the control device 8 can control so that power is supplied to the opening / closing drive device 45 from the battery 6.

[0023] With this configuration, regardless of whether one of the two types of batteries that supply power to the opening / closing drive device 45, the battery 6 housed in the shutter device 1 or an external device such as a portable battery, is used, the control device 8 can automatically select the battery and supply power to the opening / closing drive device 45. As a result, even if the battery 6 becomes unusable in an emergency, for example, the shutter curtain 44 can be opened and closed by connecting an external device such as a portable battery to a connector such as the USB port 7 without having to perform operations such as changing the wiring to the opening / closing drive device 45.

[0024] 7, the control device 8 has a power generation amount obtaining unit 81, a battery control unit 82, an opening / closing drive control unit 83, an installation position determining unit 84, a power generation device deterioration determining unit 85, a battery deterioration determining unit 86, an output unit 87, a power generation device maintenance determining unit 851, and a battery maintenance determining unit 861. The power generation amount obtaining unit 81 obtains the power generation amount of the power generation device 10, which will be described later.

[0025] As described above, the battery control unit 82 automatically determines whether the battery 6 or the USB port 7 is connected to the opening / closing drive device 45, and supplies power to the opening / closing drive device 45 from the selected power source. The battery control unit 82 also determines whether the opening / closing operation of the shutter device 1 has ended, and can acquire battery data during the opening / closing operation of the shutter device 1. The battery control unit 82 also determines whether a certain operating time has elapsed during the opening / closing operation of the shutter device 1, and can acquire sufficient charge / discharge amount data (charge / discharge curve data) of the battery 6.

[0026] The opening / closing drive control unit 83 controls the opening / closing drive device 45 to open and close the shutter device 1. The installation position determination unit 84 determines whether the installation position of the power generation device 10 is appropriate based on the power generation amount of the power generation device 10 acquired by the power generation amount acquisition unit 81. The power generation device deterioration determination unit 85 determines the deterioration state of the power generation device 10 based on the power generation amount of the power generation device 10 acquired by the power generation amount acquisition unit 81. The power generation device maintenance determination unit 851 determines whether maintenance of the power generation device 10 is necessary based on the determination result of the power generation device deterioration determination unit 85.

[0027] The battery deterioration determination unit 86 determines the deterioration state of the battery 6 based on the charge / discharge amount or the number of charge / discharge cycles of the battery 6. The battery maintenance determination unit 861 determines whether or not maintenance of the battery 6 is necessary based on the determination result of the battery deterioration determination unit 86. The output unit 87 outputs the determination results of the attachment position determination unit 84, the power generation unit deterioration determination unit 85, the battery deterioration determination unit 86, the power generation unit maintenance determination unit 851, and the battery maintenance determination unit 861.

[0028] 7, when a HEMS device is installed in a building, information can be transmitted and received to and from a server device C via an internet line. In this case, each of the determination units, i.e., an installation position determination unit 84, a power generation unit deterioration determination unit 85, a battery deterioration determination unit 86, a power generation unit maintenance determination unit 851, and a battery maintenance determination unit 861, can be provided in the server device C. With this configuration, each determination unit in the server device C can make a determination and transmit the result to the control device 8.

[0029] The power generation device 10 is a power generation device that supplies generated power to the battery 6. As shown in FIGS. 2 and 3, the power generation device 10 used in this embodiment is a panel-type power generation device, and is a solar cell that converts radiation from sunlight into energy. Like the power generation device 10A, the power generation device 10 is detachably attached to the outer surface 421 of the shutter box 4 that houses the opening / closing drive device 45. Furthermore, the power generation device 10 of the present disclosure is not limited to solar cell. Any type of energy may be converted into electricity as long as it is a power generation device that generates power using renewable energy, and the shape is not limited to panel-like. For example, it may be a device that generates power using wind power or geothermal energy.

[0030] As shown in Fig. 5, the power generating device 10A can be installed freely at any position in the left-right direction on the outer surface 421 of the shutter box 4. Also, as with the power generating device 10B shown in Figs. 3 and 6, the power generating device 10 can be installed around the opening 21 via wiring from the shutter device 1. As in this embodiment, the power generating device 10B can also be installed on the outer wall surface 22 of the building skeleton 2, but is not limited to this. With this configuration, the power generating device 10 can be installed in any position, so that the power generating device 10 can be installed in a location that receives the most sunlight, and the power generated by the power generating device 10 can be efficiently supplied to the battery 6 without being affected by the surrounding buildings or environment.

[0031] The power generating device 10 is detachably fixed to the outer surface 421 of the shutter box 4 or the periphery of the opening 21 via screws, but is not limited to this. For example, a fixing bracket may be installed on the outer surface 421 or the outer wall surface 22 of the shutter box 4 using an outdoor adhesive or concrete bond, and the power generating device 10 may be detachably attached to the fixing bracket. Furthermore, the shape and size of the power generating device 10 are not limited to those in this embodiment, and any form of power generating device may be used as long as it is capable of supplying enough power to sufficiently open and close the shutter device 1. For example, the power generating device may be attached to the entire outer surface 421 of the shutter box 4, rather than just a part of it.

[0032] As shown in Fig. 3, the wireless receiver 11 is a remote controller for operating the shutter device 1, and is usually placed inside the building on the X2 side. This allows a user to remotely operate the shutter device 1 from inside the building to open and close the opening 21 with the shutter curtain 44. Furthermore, the wireless receiver 11 does not have to be a dedicated device, and may be a terminal device such as a smartphone or tablet, or a personal computer. The wireless receiver 11 has a display unit 111.

[0033] 7, the output unit 87 of the control device 8 can transmit output information to the wireless receiver 11. This allows the determination results of the installation position determination unit 84, power generation unit deterioration determination unit 85, battery deterioration determination unit 86, power generation unit maintenance determination unit 851, and battery maintenance determination unit 861 of the control device 8 to be displayed on the display unit 111 of the wireless receiver 11. With this configuration, the determination results of the control device 8 can be received by remote control using the wireless receiver 11.

[0034] In the above, in this embodiment, the shutter device 1 has been exemplified as an opening and closing device that blocks the X1 side (outdoor side) of a window. However, the opening and closing device of the present disclosure is not limited to a shutter device. There are no limitations on the opening and closing device as long as it is provided on the X1 side of a sliding window 9 that is fitted into an opening 21 and is a device that can electrically open and close the opening 21 using an opening and closing member. For example, the opening and closing device may be a storm shutter.

[0035] Next, the control operation at the time of judgment by the mounting position judgment unit 84 will be described with reference to Fig. 8. As described above, the power generation device 10 can be installed at any position around the outer surface 421 of the shutter box 4 or the opening 21, but it is difficult to determine from the appearance which position is most appropriate. Therefore, when installing the shutter device 1, the mounting position judgment unit 84 can judge whether the mounting position of the power generation device 10 is appropriate.

[0036] 8, in step S1, the power generation amount acquiring unit 81 of the control device 8 acquires the amount of power generated per unit time of the power generation device 10. For example, the power generation amount acquiring unit 81 measures the amount of power generated for a predetermined time, and acquires the amount of power generated per unit time from the measured amount of power generated. The predetermined time is not limited as long as it is a time that can obtain an amount of power generated that is sufficient to determine whether the installation position of the power generation device 10 is appropriate, and may be, for example, one minute or ten minutes.

[0037] Furthermore, the power generation device 10 is not always placed under sunny skies, and the amount of power generated may decrease due to factors such as clouds casting shadows during the expected sunshine hours or high temperatures depending on the season, and the power generation device 10 may not be able to produce 100% of its output due to environmental influences. Taking this into consideration, the amount of power generated per day by the power generation device 10 can be calculated using an efficiency correction value.

[0038] For example, the amount of power generated per day by the power generation device 10 at the desired installation location can be calculated by multiplying the current output wattage, which is the amount of power generated per unit time by the power generation device 10, by the number of hours of sunlight per day, which is the estimated time that the power generation device 10 is irradiated with sunlight, and the calculated value can be further multiplied by an efficiency correction value to calculate the amount of power generated per day by the power generation device 10 that takes the environment into consideration. For example, 0.6 may be used as the efficiency correction value.

[0039] The installation position determination unit 84 sets a threshold value 1 for the amount of power generation per day in advance. This threshold value 1 may be set based on the amount of power generation that allows the shutter curtain 44 to perform one opening operation and one closing operation, for example.

[0040] In step S2, a predetermined threshold value 1 is compared with the daily power generation amount of the power generation device 10 taking into account the environment, calculated from the power generation amount acquired by the power generation amount acquisition unit 81 in step S1, and if the acquired power generation amount is equal to or greater than threshold value 1, the process proceeds to step S3, where the installation position determination unit 84 determines that the power generation amount of the power generation device 10 is sufficient to drive the shutter device 1, and determines that the installation position of the power generation device 10 is appropriate.

[0041] In step S2, if the amount of power generation is less than threshold value 1, the process proceeds to step S4, where the attachment position determination unit 84 determines that the amount of power generation of the power generation device 10 is insufficient to drive the shutter device 1, and determines that the attachment position of the power generation device 10 is inappropriate. The determination results of steps S3 and S4 proceed to step S5, where they are output via the output unit 87.

[0042] The determination result output from the output unit 87 may be displayed, for example, on the display unit 111 of the wireless receiver 11, or on the shutter device 1. If this control operation determines that the installation position of the power generation device 10 is inappropriate, the installation position of the detachably fixed power generation device 10 can be changed and the control operation from step S1 can be repeated again, thereby making it possible to know the installation position at which the power generation device 10 can generate electricity most efficiently.

[0043] Next, the control operations performed by the power generation unit deterioration determination unit 85 and the power generation unit maintenance determination unit 851 during determination will be described with reference to Fig. 9. The amount of power generated by the power generation unit 10 gradually decreases due to deterioration over time, but it is difficult to determine the timing for performing maintenance on the power generation unit 10 simply by checking the current amount of power generation. Therefore, the power generation unit deterioration determination unit 85 and the power generation unit maintenance determination unit 851 can determine the appropriate time for maintenance of the power generation unit 10.

[0044] 9, in step S11, the power generation amount acquiring unit 81 of the control device 8 acquires the amount of power generated per unit time of the power generation device 10. For example, the power generation amount acquiring unit 81 measures the amount of power generated for a predetermined time, and acquires the amount of power generated per unit time from the measured amount of power generated. The predetermined time is not limited as long as it is a time that can obtain an amount of power generated that is sufficient to determine whether or not there is an abnormality in the power generation device 10, and may be, for example, one minute or ten minutes.

[0045] A threshold value for the amount of power generated per unit time is set in advance in the power generation device deterioration determination unit 85. This threshold value 2 may be a numerical value at which it is determined that maintenance of the power generation device 10 is necessary, and a predetermined threshold value such as a numerical value obtained by subtracting 80% of the amount of power generated from the initial amount of power generated per unit time of the power generation device 10 is used.

[0046] Threshold 2 set in power generation plant deterioration determination unit 85 can be flexibly set according to the environment during control, for example, by referring to the average amount of sunlight irradiation for each month. Specifically, threshold 2 can be set differently for June, when the sunshine hours are short throughout the year, and for July, when the sunshine hours are long.

[0047] In step S12, the power generation amount acquired by the power generation amount acquisition unit 81 in step S1 is compared with a predetermined threshold value 2, and if the acquired power generation amount is equal to or greater than threshold value 2, the process proceeds to step S13, where the power generation device deterioration determination unit 85 determines that the power generation amount of the power generation device 10 is sufficient even when compared to the initial state, and determines that there is no abnormality in the power generation device 10.

[0048] In step S12, if the acquired power generation amount is less than threshold value 2, the process proceeds to step S14, where the power generation device deterioration determination unit 85 determines that the power generation amount of the power generation device 10 has significantly decreased compared to the initial state and that the power generation device 10 is in a deteriorated state. The determination results of steps S13 and S14 proceed to step S15, where they are output via the output unit 87.

[0049] If the determination result output in step S15 indicates that the power generation device 10 is in good condition and has no abnormalities, the process proceeds to step S17. In step S17, the power generation device maintenance determination unit 851 determines, based on the determination result of the power generation device deterioration determination unit 85, that maintenance of the power generation device 10 is not required.

[0050] On the other hand, if the determination result output in step S15 indicates that the power generation device 10 is in a deteriorated state and is not in good condition, the process proceeds to step S18. In step S18, the power generation device maintenance determination unit 851 determines that maintenance of the power generation device 10 is required based on the determination result of the power generation device deterioration determination unit 85.

[0051] The determination results of steps S17 and S18 proceed to step S15 and are output via the output unit 87. The determination results output from the output unit 87 may be displayed, for example, on the display unit 111 of the wireless receiver 11, or may be displayed on the shutter device 1. Furthermore, if it is determined in step S18 that maintenance of the power generation device 10 is required, an alert may be sent via the output unit 87. The alert may be, for example, an alarm sounded from the shutter device 1, or information may be sent by email to the user's mobile terminal.

[0052] This control operation allows the deterioration state of the power generation device 10 to be known, and by prompting maintenance of the power generation device 10 at the appropriate time, the power generation efficiency of the power generation device 10 can be increased, and the usability of the shutter device 1 can be improved.

[0053] Next, the control operations performed by the battery degradation determination unit 86 and the battery maintenance determination unit 861 during determination will be described with reference to Fig. 10. The battery 6 has a limited lifespan and therefore requires periodic inspection and replacement, but it is difficult to determine from the outside when maintenance should be performed on the battery 6. Therefore, the battery degradation determination unit 86 and the battery maintenance determination unit 861 can determine the appropriate time for maintenance of the battery 6.

[0054] 10, in step S21, it is first determined whether or not the opening and closing operation of the shutter device 1 has finished. If the opening and closing operation has finished, the process proceeds to step S22, and if the opening and closing operation has not finished, this step is repeated. This step makes it possible to obtain battery data during the opening and closing operation of the shutter device 1.

[0055] In step S22, it is determined whether a certain operating time has elapsed. If the certain operating time of the shutter device 1 has elapsed, the process proceeds to step S23, and if the certain time has not elapsed, this step is repeatedly executed. By this step, it is possible to obtain a sufficient amount of charge / discharge amount data (charge / discharge curve data) of the battery 6, and also to obtain a sufficient number of times the battery 6 has been charged / discharged.

[0056] In step S23, the battery degradation determination unit 86 acquires the charge / discharge amount or the number of charge / discharge cycles of the battery 6, and determines whether the acquired charge / discharge amount or the number of charge / discharge cycles is less than a preset threshold value 3. Specifically, for example, it determines whether the voltage of the battery 6, which can be acquired from the acquired charge / discharge curve data, is less than a preset voltage threshold value. Alternatively, it determines whether the acquired number of charge / discharge cycles is less than a preset threshold value for the number of charge / discharge cycles. If the current charge / discharge amount or the number of charge / discharge cycles of the battery 6 is less than threshold value 3, the process proceeds to step S24, where the battery degradation determination unit 86 determines that the battery 6 is not in a deteriorated state and therefore is not abnormal.

[0057] In step S23, the current charge / discharge amount or the number of charge / discharge cycles of the battery 6 is compared, and if the current charge / discharge amount or the number of charge / discharge cycles of the battery 6 is equal to or greater than threshold value 3, the process proceeds to step S25, where the battery degradation determination unit 86 determines that the battery 6 is in a deteriorated state. The determination results of steps S24 and S25 proceed to step S26, where they are output via the output unit 87.

[0058] In step S27, if the determination result output in step S26 indicates that the battery 6 is not in a deteriorated state and is in good condition, the process proceeds to step S28. In step S28, the battery maintenance determination unit 861 determines, based on the determination result of the battery deterioration determination unit 86, that maintenance of the battery 6 is not necessary.

[0059] On the other hand, if the determination result output in step S26 indicates that the battery 6 is in a deteriorated state and is not in good condition, the process proceeds to step S29. In step S29, the battery maintenance determination unit 861 determines that maintenance of the battery 6 is necessary based on the determination result of the battery deterioration determination unit 86.

[0060] The determination results of steps S28 and S29 proceed to step S30 and are output via the output unit 87. The determination result output from the output unit 87 may be displayed, for example, on the display unit 111 of the wireless receiver 11, or may be displayed on the shutter device 1. Furthermore, if it is determined in step S29 that maintenance of the battery 6 is required, an alert may be sent via the output unit 87. The alert may be, for example, an alarm sounded from the shutter device 1, or information may be sent by email to the user's mobile terminal.

[0061] This control operation makes it possible to predict the deterioration state of the battery 6, and by prompting maintenance of the battery 6 at an appropriate time, the usability of the shutter device 1 can be improved.
