In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention. In the drawings, the same or similar parts may be denoted by the same reference numerals and redundant description may be omitted. In addition, the shape and size of elements in the drawings may be exaggerated for a clearer description.

  In the entire specification, when a part includes a component, “includes”, “have”, or “comprises”, this does not exclude other components unless otherwise stated. This means that it can further include the following components.

  Hereinafter, a facility device according to an embodiment of the present invention will be described with reference to the drawings. This equipment is provided later in the building and includes equipment members provided on the outer wall side of the building, and the equipment members are driven by electric power from the inner wall side. This embodiment demonstrates the case where an installation member is a shutter curtain. However, the equipment member of the present invention is not limited to an electric shutter curtain, and can be applied to, for example, an electric curtain, an awning, a sunshade louver, and the like. This equipment member is a member that opens and closes openings such as windows, sliding doors, doors, and louver windows.

FIG. 1 is a diagram illustrating an example of a schematic configuration of an electric shutter device 1 (facility device) according to an embodiment of the present invention. Here, the electric shutter device 1 may be an example of an equipment device.
The electric shutter device 1 is provided at an opening of a building 2 such as a glass window 11, for example, and is configured to be able to close or open the outdoor side of the glass window 11 with a shutter curtain 6.
The electric shutter device 1 opens or closes the shutter curtain 6 based on an operation command from the user. For example, the electric shutter device 1 may acquire the operation command by wirelessly transmitting the operation command from the remote controller, or acquire the operation command by operating the operation unit provided in the electric shutter device 1 by the user. May be.

For example, the electric shutter device 1 is retrofitted to the building 2 at the time of renovation.
As shown in FIG. 1, the electric shutter device 1 includes a power feeding unit 3, a power feeding coil 4, a shutter box 5 (storage box), and a shutter curtain 6. The shutter box 5 is provided with a power receiving coil 7 and an electromagnetic shield 8. Further, the shutter box 5 includes an equipment driving unit 51 and a shaft 60. The shutter box 5 may be an example of a storage box. That is, the storage box stores the facility member and the facility drive unit 51.

The power feeding unit 3 is provided on the inner wall 21 side of the building 2. The power feeding unit 3 is connected to the power feeding coil 4. The power feeding unit 3 supplies power to the power feeding coil 4.
The power feeding unit 3 includes a power plug 31 and a power control unit 32.
The power plug 31 is inserted into the outlet 12 to acquire AC power from a household power source, and supplies the acquired AC power (AC 100 V or AC 200 V) to the power control unit 32.

  The power control unit 32 converts AC power supplied via the power plug 31 into predetermined DC power. The power supply control unit 32 converts the converted DC power into AC power having a predetermined frequency and outputs the AC power to the power feeding coil 4. This frequency should just be a frequency which can transmit electric power from the feed coil 4 to the receiving coil 7 by a magnetic field resonance system. The power plug 31 and the power control unit 32 may be configured integrally. Moreover, although this embodiment demonstrates the case where electric power is supplied from a commercial power supply, it is not limited to this, Electric power may be supplied to the electric power feeding part 3 from the storage battery in a room | chamber interior. Further, the power plug 31 may have a function of converting AC power from a commercial power source into predetermined power. Here, the voltage supplied from the power supply unit 3 to the power supply coil 4 is lower than a voltage that requires official qualification such as an electrician.

The feeding coil 4 is provided on the inner wall 21 side of the building 2. For example, the feeding coil 4 is fixed to the fixed plate 41 and attached to the inner wall 21 of the building 2 via the fixed plate 41. In the present embodiment, the feeding coil 4 is attached to the inner wall 21 at the upper part of the glass window 11 in the building 2.
The power feeding coil 4 feeds the power output from the power feeding unit 3 to the power receiving coil 7 by magnetic field resonance with the power receiving coil 7. The power feeding coil 4 and the power receiving coil 7 may be disposed so as to be close to each other.

  The shutter box 5 is provided on the outer wall 22 side and at the top of the electric shutter device 1. The shutter box 5 includes a power receiving coil 7, an electromagnetic shield 8, a shaft 60, and an equipment driving unit 51.

  The power receiving coil 7 is provided on the outer wall 22 side of the building 2 and receives power from the power feeding coil 4 in a contactless manner by magnetic field resonance. The power received by the power receiving coil 7 is supplied to the equipment driving unit 51 and is mainly used as power for driving the shutter curtain 6.

  For example, the power receiving coil 7 is fixed to the fixed plate 71 and attached to the outer wall 22 of the building 2 via the fixed plate 71. In the present embodiment, the power receiving coil 7 is attached to the outer wall 22 in the upper part of the glass window 11 in the building 2.

  The electromagnetic shield 8 is provided on the outer wall 22 side. The electromagnetic shield 8 is interposed between the power receiving coil 7 and a metal member provided on the outer wall 22 side of the building 2. This metal material is, for example, piping, wiring, sashes, shutter curtains 6 and the like disposed around the power receiving coil 7. FIG. 2 is an image view of the power receiving coil 7 according to the present embodiment as viewed from the front. Here, the front surface is a surface of the power receiving coil 7 on the inner wall 21 side. As shown in FIG. 2, the position and size of the electromagnetic shield 8 are such that, for example, when the power receiving coil 7 is viewed from the front, the metal member (for example, the shutter curtain 6) behind the power receiving coil 7 cannot be seen. It is set to a position and size of about. For example, the electromagnetic shield 8 is a ferrite sheet. The capacitor 9 is a resonance capacitor, and may be a stray capacitance or a physical capacitance of a capacitor.

  The shaft 60 is connected to the upper end portion of the shutter curtain 6 and the equipment driving unit 51 and is a winding unit that winds up the shutter curtain 6. The shaft 60 is rotationally driven in the forward and reverse directions by the equipment driving unit 51. In accordance with the rotation of the shaft 60, the shutter curtain 6 is unwound (when the shutter curtain 6 is closed) or wound (when the shutter curtain 6 is opened). The shutter curtain 6 wound around the shaft 60 is accommodated in the shutter box 5.

  The equipment driving unit 51 is provided on the outer wall 22 side, and drives the shutter curtain 6 that is an equipment member according to the power received by the power receiving coil 7.

  Below, the effect of the electromagnetic shielding body 8 is demonstrated using FIG.3 and FIG.4. In describing FIGS. 3 and 4, the case where the metal member is the shutter curtain 6 will be described.

  FIG. 3 is a diagram for explaining the electric shutter device when the electromagnetic shield 8 according to the present embodiment is not provided. FIG. 4 is a diagram for explaining the electric shutter device 1 provided with the electromagnetic shield 8 according to the present embodiment.

  When the equipment driving unit 51 rotates the shaft 60 to wind or unwind the shutter curtain 6, the winding diameter of the shutter curtain 6 increases or decreases. The distance between the power receiving coil 7 and the shutter curtain 6 is changed by increasing or decreasing the winding diameter of the shutter curtain 6. For example, when the equipment driving unit 51 winds up the shutter curtain 6, the winding diameter of the shutter curtain 6 increases. Accordingly, the shutter curtain 6 approaches the power receiving coil 7. Here, when the shutter curtain 6 is a metal member, when the shutter curtain 6 approaches the power receiving coil 7, the inductance of the power receiving coil 7 changes. Therefore, the coupling coefficient between the power receiving coil 7 and the power feeding coil 4 changes, and the resonance frequency shifts. Therefore, the efficiency of power transmission from the power feeding coil 4 to the power receiving coil 7 is reduced. In other words, as shown in FIG. 3, when the shutter curtain 6, which is a metal member, is present in the vicinity of the power feeding coil 4 and the power receiving coil 7 that are magnetically resonating, a coupling magnetic field 200 between the power feeding coil 4 and the power receiving coil 7. However, under the influence of the shutter curtain 6, the power transmission loss increases.

  On the other hand, as shown in FIG. 4, in the electric shutter device 1 according to the present embodiment, an electromagnetic shield 8 is interposed between the power receiving coil 7 and a metal member, for example, the shutter curtain 6. Therefore, the electromagnetic shield 8 suppresses the influence of the shutter curtain 6 disposed on the outer wall 22 side on the coupling coefficient between the power feeding coil 4 and the power receiving coil 7. That is, the resonance frequency does not shift because the inductance of the power receiving coil 7 does not change even when the shutter curtain 6 approaches. Therefore, it is possible to suppress a decrease in efficiency in power transmission from the power feeding coil 4 to the power receiving coil 7.

  As described above, in the electric shutter device 1 according to the present embodiment, the electromagnetic shield 8 is interposed between the power receiving coil 7 and the shutter curtain 6, so that the shutter curtain 6 can approach the power receiving coil 7. The coupling magnetic field 100 between the feeding coil 4 and the receiving coil 7 is not affected by the shutter curtain 6. In other words, the electromagnetic shielding body 8 suppresses the coupling magnetic field 100 from leaking to the shutter curtain 6 by interposing the electromagnetic shielding body 8 between the power receiving coil 7 and the shutter curtain 6. Thereby, highly efficient power transmission from the feeding coil 4 to the receiving coil 7 can be realized.

Below, the installation drive part 51 which concerns on this embodiment is demonstrated. FIG. 5 is a diagram illustrating an example of a schematic configuration of the equipment driving unit 51 according to the present embodiment.
As shown in FIG. 5, the facility driving unit 51 includes a power storage unit 52, a communication unit 53, a control unit 54, and a motor 55.

The power storage unit 52 stores the power received by the power receiving coil 7 from the power feeding coil 4 due to magnetic field resonance. For example, the power storage unit 52 is a secondary battery. For example, the power storage unit 52 is connected to the power receiving coil 7 in a wired or wireless manner. When the power storage unit 52 is connected to the power receiving coil 7 by wire, the power storage unit 52 stores the power received through the wire. On the other hand, when the power storage unit 52 is wirelessly connected to the power receiving coil 7, the power storage unit 52 stores the power received wirelessly from the power receiving coil 7. Here, the wireless means non-contact power transmission, for example, an electric field coupling method, an electromagnetic induction method, a radio wave method, a magnetic field resonance method, or the like.
The electric power stored in the power storage unit 52 is supplied to each unit of the equipment driving unit 51.

The communication unit 53 transmits and receives information from the outside via a communication network. This information is, for example, an operation command for opening or closing the shutter curtain 6.
The control unit 54 includes, for example, a CPU (Central Processing Unit), a storage device, and the like, and controls driving of the motor 55 according to an operation command.
The motor 55 is a drive unit that rotationally drives the shaft 60, and is composed of, for example, a DC motor. The motor 55 rotates forward, reversely, or stops rotating based on a drive signal from the control unit 54. Here, the motor 55 rotates based on the drive signal from the control unit 54 using the electric power stored in the power storage unit 52 as a drive source. Thereby, the installation drive part 51 can open and close the shutter curtain 6 electrically.

  Below, operation | movement of the electric shutter apparatus 1 which concerns on this embodiment is demonstrated. FIG. 6 is a sequence diagram showing the operation of the electric shutter device 1 according to this embodiment.

  The power supply unit 3 supplies power to the power supply coil 4 (step S101). The power feeding coil 4 performs magnetic field resonance with the power receiving coil 7 based on the power supplied from the power feeding unit 3 (step S102). Thereby, the electric power fed from the power feeding unit 3 is fed to the power receiving coil 7 in a non-contact manner.

The power receiving coil 7 receives electric power from the power feeding coil 4 in a contactless manner by magnetic field resonance (step S103). The power storage unit 52 of the facility drive unit 51 stores the power received by the power receiving coil 7 from the power feeding coil 4 due to magnetic field resonance (step S104).
When acquiring the drive command via the communication unit 53, the control unit 54 outputs a drive signal to the motor 55 (step S105).
Based on the drive signal from the control unit 54, the motor 55 rotates using the electric power stored in the power storage unit 52 as a drive source. Thereby, the equipment drive unit 51 can open and close the shutter curtain 6 (equipment member) using the electric power stored in the power storage unit 52 (step S106).

  The electric shutter device 1 according to the present embodiment described above is provided on the inner wall 21 side of the building 2 and the outer wall 22 side of the building 2 and receives power from the feeding coil 4 by magnetic field resonance. The coil 7 includes a shutter curtain 6 provided on the outer wall 22 side, and an equipment driving unit 51 provided on the outer wall 22 side for driving the shutter curtain 6 according to the power received by the power receiving coil 7. Thereby, when constructing the electric shutter device 1 that is provided later on the outer wall 22 side, the construction can be easily performed on the building 2.

  The electric shutter device 1 according to the above-described embodiment is driven by obtaining electric power from a power supply device (for example, a commercial power supply) on the inner wall 21 side. In this case, the electric shutter device 1 transmits the power from the power supply device on the inner wall 21 side from the power feeding coil 4 to the power receiving coil 7 in a non-contact manner. Therefore, when the electric shutter device 1 is to be retrofitted to an existing building, wiring work of a power cable for supplying power from the power supply device on the inner wall 21 side to the equipment driving unit 51 on the outer wall 22 side (the power cable It is not necessary to make a hole in the wall for wiring from the room to the outside. Thereby, the user can construct the electric shutter device 1 easily. Further, the voltage supplied from the power supply unit 3 to the power supply coil 4 is lower than the voltage that requires official qualification such as an electrician. That is, the electric shutter device 1 can be applied to the building 2 without an official qualification such as an electrician.

  In addition, the equipment drive unit 51 according to the above-described embodiment may include a transformer unit that converts the power supplied from the power storage unit 52 into a predetermined voltage.

  Moreover, the form comprised integrally may be sufficient as the receiving coil 7, the stationary plate 71, and the electromagnetic shielding body 8 which concern on the above-mentioned embodiment. However, the fixing plate 71 is for fixing the power receiving coil 7 or the electromagnetic shield 8 to the building 2. Therefore, depending on the form in which the power receiving coil 7 and the electromagnetic shield 8 are fixed to the building 2, the fixing plate 71 may not be used. The same applies to the fixed plate 41. That is, the fixed plate 41 and the fixed plate 71 according to the present embodiment are not necessarily essential configurations.

  The electromagnetic shield 8 according to the above-described embodiment may be provided between the power receiving coil 7 and the metal member so as to cover the power receiving coil 7.

  Moreover, you may make it implement | achieve the installation drive part 51 in embodiment mentioned above with a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).
