FIG. 10 is a schematic diagram of a light control device according to an eighth embodiment.

Hereinafter, with reference to the drawings, first, a basic form as a basis of the first to eighth embodiments will be described, and then, the first to eighth embodiments will be described.

(Basic form)
As shown in FIG. 1, the light control device 1 according to the basic configuration includes a light control member 2, a control unit 3, and a power feeding unit 4.

The light control member 2 reversibly changes at least one of the reflectance and transmittance in the light wavelength band by electrochromism. In other words, the light control member 2 has an electrochromic element using an electrochromic material, and at least one of reflectance and transmittance in the light wavelength band is reversible by voltage application by the power feeding unit 4. To change. As the light control member 2, it is light control glass or a light control film, for example.

The electrochromic element used for the light control member 2 has an advantage that it consumes power only when the reflectance or transmittance is changed, and does not consume power otherwise. Electrochromic elements include a transmission type and a reflection type.

In this basic form, the light wavelength band refers to a wavelength band (frequency band) including a visible light wavelength band, an infrared wavelength band, and an ultraviolet wavelength band.

As an example of the light control member 2 whose light transmittance in the wavelength band of light changes reversibly, it is a member whose light transmittance to sunlight changes reversibly.

Further, as another example of the light control member 2 in which the transmittance in the wavelength band of light reversibly changes, a first state that transmits visible light (transmission state) and a second state that blocks visible light (Blocking state).

The control unit 3 changes at least one of the reflectance and transmittance of the light control member 2 based on a predetermined condition. The control unit 3 changes at least one of the reflectance and transmittance of the dimming member 2 by controlling voltage application from the power feeding unit 4 to the dimming member 2.

For example, when the light control member 2 is a member whose transmittance changes reversibly between the transmission state and the blocking state, the control unit 3 determines whether the first state and the first state of the light control member 2 are based on the above conditions. Switch between 2 states.

The power feeding unit 4 applies a voltage suitable for the dimming member 2 to the dimming member 2 by supplying power from a power source 5 such as a commercial power source. Power feeding from the power feeding unit 4 to the light control member 2 may be wired power feeding or non-contact power feeding.

In the light control device 1 of this basic form described above, the control unit 3 can change at least one of the reflectance and transmittance of the light control member 2.

(Embodiment 1)
In the first embodiment, a case will be described in which a light control panel 2a as the light control member 2 is provided on an inner surface 71a of a bathroom (bath unit) 71 as shown in FIGS. In addition, about the component similar to the light modulation apparatus 1 (refer FIG. 1) of a basic form, the same code | symbol is attached | subjected and description is abbreviate | omitted.

Conventionally, when taking a bath, heat shock in the bathroom in winter has been a problem.

Therefore, in the present embodiment, as shown in FIG. 3, a light control panel (light control wall) 2 a is laid in the bathroom 71 as the light control member 2. That is, the light control member 2 of the present embodiment is a light control panel 2 a provided along the inner surface 71 a of the bathroom 71.

The light control device 1 of this embodiment is provided with the light control panel 2a as the light control member 2, the external operation panel 3a, and the bathroom operation panel 3b, as shown in FIG.

The light control panel 2a of this embodiment is provided along the inner surface 71a of the bathroom 71, as shown in FIG. The light control panel 2a may be provided on all of the four walls 711, the ceiling 712 (see FIG. 5), and the floor 713 (see FIG. 5) of the bathroom 71, or may be provided on a part of them. It may be. The power feeding from the power feeding unit 4 shown in FIG. 2 to the light control panel 2a may be wired power feeding or non-contact power feeding.

The light control panel 2a has a reflectance of 100% in the winter and a reflectance of 10% in the summer when bathing. In addition to the bathing, the reflectance is 10%.

As shown in FIG. 2, the external operation panel 3 a is installed outside the bathroom 71 and includes a control unit 3 and an operation unit 31. The control part 3 controls the voltage application from the electric power feeding part 4 to the light control panel 2a so that the reflectance of the light control panel 2a may change. The external operation panel 3a has a function of switching various modes, a function of setting a calendar (summer, winter, and intermediate period), and a function of setting a reflectance.

The bathroom operation panel 3b is installed in the bathroom 71 and has the same function as the external operation panel 3a.

By the way, when the light control panel 2a is not provided on the inner surface 71a of the bathroom 71, the heat in the bathroom 71 is radiated by the wall 711 or the like, so that the temperature experienced by the bather may decrease in winter.

On the other hand, in the case of this embodiment, the heat (infrared heat) in the bathroom 71 is reflected by the light control panel 2a by increasing the reflectance of the light control panel 2a and lowering the transmittance. Heat dissipation to the outside of the bathroom 71 can be reduced, and as a result, a decrease in the bather's perceived temperature can be suppressed.

On the other hand, in the summer, the heat in the bathroom 71 can be dissipated to the outside of the bathroom 71 by lowering the reflectance of the light control panel 2a and increasing the transmittance, so bathing is performed so as not to be too hot. be able to.

As described above, the light control panel 2a of the present embodiment uses an electrochromic material that reversibly changes the reflectance and transmittance in the infrared wavelength band.

Next, the operation of the light control device 1 according to this embodiment will be described with reference to FIG. First, either the external operation panel 3a or the bathroom operation panel 3b accepts a bath reservation operation (S1, S2 in FIG. 4). When the operation is accepted in steps S1 and S2, the reflectance of the light control panel 2a becomes 100% under the control of the control unit 3 (S3). After that, when the user takes a bath and leaves the bathroom 71, when the power of the bathroom operation panel 3b is turned off (S4), the reflectance of the light control panel 2a is 100% to 10% by the control of the control unit 3 (S5).

Next, the difference in the sensible temperature (working temperature) with and without the light control panel 2a will be described with reference to FIGS. Here, as shown in FIG. 5, the size of the bathroom 71 is length (depth) L1 = 1.6 m, width W1 = 1.6 m, height H1 = 2.0 m, and the size of the bathtub 714 is long. The depth (depth) L2 = 1.6 m, the width W2 = 0.8 m, and the height H2 = 0.6 m. The size of the bathroom 71 and the size of the bathtub 714 are examples.

As shown in FIG. 6, the temperature of the wall 711, ceiling 712, floor 713, and bathtub 714 is 10 ° C. in winter and 30 ° C. in summer. The temperature of the wall 711, the ceiling 712, and the floor 713 provided with the light control panel 2a is also set to 10 ° C. in winter and 30 ° C. in summer. The temperature of the hot water surface is 42 ° C. in the winter and 38 ° C. in the summer, and the surface temperature of the person (the bather) is 33 ° C. The reflectance of the wall 711, the ceiling 712, the floor 713 and the bathtub 714 is 10%, the reflectance of the hot water surface is 2%, and the reflectance of the bather's surface is 10%. The reflectance of the wall 711, the ceiling 712, and the floor 713 provided with the light control panel 2a is 100% in winter and 10% in summer.

FIG. 7 shows the difference in temperature sensed by the presence or absence of the light control panel 2a. In winter, when the light control panel 2a is provided, when the light control panel 2a is provided, the perceived temperature is about 4 ° C. when the cover of the bathtub 714 is closed, and the cover of the bathtub 714 is opened. The temperature rises by about 7 ° C. That is, in winter, regardless of whether the bathtub 714 is opened or closed, the temperature experienced by the bather is higher when the light control panel 2a is provided than when the light control panel 2a is not provided. In addition, the temperature experienced by the bather is higher when the light control panels 2a are provided on all six surfaces of the bathroom 71 than when the light control panels 2a are provided on the four surfaces of the bathroom 71.

On the other hand, in the case of summer, if the reflectance of the light control panel 2a is set to 10%, the sensory temperature hardly changes with or without the light control panel 2a. When the reflectance of the light control panel 2a is set to 100%, the sensible temperature when the light control panel 2a is provided is slightly higher than that when the light control panel 2a is not provided.

In the light control device 1 of this embodiment described above, the light control member 2 is the light control panel 2a provided along the inner surface 71a of the bathroom 71, and the reflectance and transmittance in the light wavelength band are reversible. To change.

Can be suppressed. That is, compared with the case where the light control panel 2a is not provided, possibility that a bather will receive a heat shock can be reduced.

Moreover, in the light control apparatus 1 of this embodiment, the hot water of the bathtub 714 can be kept warm by making the reflectance of the light control panel 2a high.

On the other hand, by reducing the reflectance of the light control panel 2a and increasing the transmittance in summer, in the light control device 1 of the present embodiment, the interior of the bathroom 71 is the same as when the light control panel 2a is not provided. Since heat can be radiated from the interior, the interior of the bathroom 71 can be brought to a comfortable temperature.

(Embodiment 2)
Embodiment 2 demonstrates the case where the light control panel 2a as the light control member 2 is provided in the bathroom door 2b, as shown in FIG. In addition, about the component similar to the light modulation apparatus 1 (refer FIG. 1) of a basic form, the same code | symbol is attached | subjected and description is abbreviate | omitted.

Therefore, in the present embodiment, the bathroom door 2b provided at the entrance / exit of the bathroom 71 can be a door having a dimming function, and the dimming state can be switched according to the preference of the bather. That is, the light control member 2 of this embodiment is a bathroom door 2 b provided at the entrance of the bathroom 71.

The light control device 1 of the present embodiment includes a bathroom door 2b as a light control member 2, an external operation panel 3a, and a bathroom operation panel 3b. An open / close sensor 61 that detects the opening / closing of the bathroom door 2b and a door sensor 62 that detects the opening / closing of the door to the bathroom (dressing room) are connected to the external operation panel 3a.

The bathroom door 2b of this embodiment is provided at the entrance of the bathroom 71 as shown in FIGS. As for the bathroom door 2b, the light control panel 2a is provided in all the translucent areas. The power supply from the power supply unit 4 shown in FIG. 8 to the bathroom door 2b (the light control panel 2a) may be a wired power supply using a door frame or a non-contact power supply. The bathroom door 2b may be a folding type or a sliding door type.

When the transmittance of the light control panel 2a is 90%, the bathroom door 2b provided with the light control panel 2a transmits light of the bathroom 71 in the light control panel 2a as shown in FIG. On the other hand, when the transmittance of the light control panel 2a is 10%, the light in the bathroom 71 is blocked in the light control panel 2a as shown in FIG.

As shown in FIG. 8, the external operation panel 3 a is installed outside the bathroom 71 and includes a control unit 3 and an operation unit 31. The control part 3 controls the voltage application from the electric power feeding part 4 to the light control panel 2a so that the reflectance of the light control panel 2a of the bathroom door 2b may change. The external operation panel 3a has a function of switching various modes, a function of setting a calendar (summer, winter, and intermediate period), and a function of setting a reflectance. Furthermore, the external operation panel 3 a acquires the detection result about the opening / closing of the bathroom door 2 b from the opening / closing sensor 61, and acquires the detection result about the opening / closing of the bathroom door from the door sensor 62.

Next, the operation of the light control device 1 according to the present embodiment will be described with reference to FIG. First, the external operation panel 3a accepts a dimming selection operation (S11 in FIG. 11). Note that the bathroom operation panel 3b may accept an operation for dimming selection. When the operation is accepted in step S11, the transmittance of the light control panel 2a is changed to 90% by the control of the control unit 3 (S12). Thereafter, when the user opens the bathroom door 2b, the open / close sensor 61 detects opening / closing of the bathroom door 2b (S13). Thereafter, the user starts bathing. When another person other than the bather opens the bathroom door during bathing, the door sensor 62 detects opening and closing of the bathroom door (S14). Then, the transmittance of the light control panel 2a is changed from 90% to 10% (S15). Thereafter, when the user leaves the bathroom 71 and the bathroom door 2b is opened and closed (S16), the transmittance of the light control panel 2a changes from 10% to 90% (S17).

In the light control device 1 of the present embodiment described above, the light control member 2 is a bathroom door 2b having a first state that transmits visible light and a second state that blocks visible light. Thereby, in the light modulation apparatus 1 of this embodiment, it can be used according to a bather's liking and a bather's privacy can be ensured.

Moreover, in the light control device 1 of this embodiment, the light control member 2 is also the bathroom door 2b from which the reflectance in the wavelength band of light changes reversibly. Thereby, in the light control apparatus 1 of this embodiment, since the temperature in the bathroom 71 can be made high by making the reflectance of the bathroom door 2b (light control panel 2a) high in winter, a heat shock is suppressed. can do. Moreover, in the light modulation apparatus 1 of this embodiment, the heat retention effect of the hot water of the bathtub 714 can be heightened by making the reflectance of the bathroom door 2b (light control panel 2a) high. In addition, the transmittance | permeability of the bathroom door 2b (light control panel 2a) in the case of winter is 10%, for example.

(Embodiment 3)
Embodiment 3 demonstrates the case where the light control member 2 is provided in the window glass 721, or the light control member 2 is the roofing material 2d and the skylight glass 2e, as shown in FIG. In addition, about the component similar to the light modulation apparatus 1 (refer FIG. 1) of a basic form, the same code | symbol is attached | subjected and description is abbreviate | omitted.

In conventional dwelling units (buildings), sunlight directly from the window glass was often dazzling, hot and uncomfortable. In particular, the summer sun is strong and uncomfortable. In addition, the deterioration of the interior and furniture is accelerated by sunlight. Furthermore, in summer, heat accumulates during non-air-conditioning and in the attic, increasing the heat load and causing discomfort when entering the room. On the other hand, if the sunlight is blocked, the field of view deteriorates, resulting in a closed and compressed space.

Therefore, in this embodiment, as shown in FIG. 13, an attachable / detachable electrochromic film (EC film) 2 c is attached to the window glass 721 of the dwelling unit (building) 72.

The light control device 1 of this embodiment includes an EC film 2c as a light control member 2, a controller 3c, and a power feeding unit 4, as shown in FIG. The light control device 1 of the present embodiment further includes a human sensor 63, a solar radiation sensor 64, and a temperature sensor 65.

The light control member 2 of this embodiment is an EC film 2c provided on a window glass 721 attached to the window of the dwelling unit 72 as shown in FIG. In the present embodiment, the EC film 2 c is installed on the outer surface of the window glass 721. Power feeding from the power feeding unit 4 (see FIG. 12) to the EC film 2c is non-contact power feeding. The EC film 2c is detachably attached to the window glass 721. Thereby, the EC film 2c can be attached to or removed from the window glass 721 according to a necessary time such as summer. Further, the EC film 2c is not attached to all the window glass of the dwelling unit 72, but the EC film 2c may be attached to a window glass at a necessary place such as a window on the west side or the second floor.

Further, a solar radiation sensor 64 and a temperature sensor 65 are attached to the window glass 721. The solar radiation sensor 64 measures the amount of solar radiation. The temperature sensor 65 is installed on the indoor side of the window glass 721 and measures the room temperature. The measurement result of the solar radiation sensor 64 and the measurement result of the temperature sensor 65 are output to the controller 3c.

The controller 3c controls the transmittance of the EC film 2c according to the measurement results of the solar radiation sensor 64 and the temperature sensor 65. Further, the controller 3c can change the transmittance of the EC film 2c by a signal from the terminal device (remote terminal) 79 or the touch panel 722.

Moreover, in this embodiment, as shown in FIG. 14, the roofing material 2d is made of EC glass. That is, the other light control member 2 of this embodiment is the roofing material 2d which consists of EC glass. It is preferable to use EC glass at least for the roofing material of the bedroom.

If you want to see the starry sky or take in sunlight, adjust the transmittance of the roofing material 2d to 100%, and otherwise adjust the transmittance of the roofing material 2d to 10%.

Furthermore, in this embodiment, as shown in FIG. 15, the skylight glass 2e is made of EC glass. That is, still another light control member 2 of the present embodiment is a skylight glass 2e attached to the skylight of the dwelling unit 72.

Further, a solar radiation sensor 64 and a temperature sensor 65 are attached to the skylight glass 2e. The solar radiation sensor 64 is installed on the outdoor side of the skylight glass 2e and measures the amount of solar radiation. The temperature sensor 65 is installed on the indoor side of the skylight glass 2e and measures the room temperature.

The controller 3c of the controller 3c uses the measurement results of the human sensor 63, the solar radiation sensor 64, and the temperature sensor 65, and the transmittance of the skylight glass 2e according to the presence / absence of a person in the daytime and the wake-up time. To control.

Moreover, a small solar cell 5a is installed on the outdoor side of the lower part of the skylight glass 2e. Thereby, an independent power supply can be secured.

Furthermore, the controller 3c can display the amount of reduction in lighting and air conditioning costs when the transmittance of the skylight glass 2e is set based on the measurement results of the solar radiation sensor 64 and the temperature sensor 65.

In addition, when waking up, the control unit 3 of the controller 3c controls the skylight glass 2e so that the transmittance increases as time elapses.

Next, the operation of the light control device 1 according to the present embodiment will be described with reference to FIG. First, when the human sensor 63 detects a person (S21 in FIG. 16), when the measurement value of the solar radiation sensor 64 is less than a certain value (S22), when the measurement value of the temperature sensor 65 is less than a certain value ( S23) When the current time becomes the set time of the timer (time switch) (S24), the transmittance of the light control member 2 (EC film 2c, roofing material 2d, skylight glass 2e) is controlled by the control unit 3. 100% (S25). Thereafter, the user operates the device with the touch panel (S26). When the mode switching button of the controller 3c is pressed (S27), the light control member 2 changes the color density (S28). Thereafter, when the human sensor 63 no longer detects a person (S29), the measurement value of the solar radiation sensor 64 exceeds a certain value (S30), or the measurement value of the temperature sensor 65 exceeds a certain value (S31). ), The transmittance of the light control panel changes from 100% to 0% under the control of the control unit 3 (S32).

In the light control device 1 of the present embodiment described above, the light control member 2 (EC film 2c) is provided outside the window glass 721 and reversibly changes the transmittance with respect to sunlight. Thereby, in the light modulation apparatus 1 of this embodiment, the heat shielding effect with respect to solar radiation heat can be heightened, so that the transmittance | permeability of the light modulation member 2 is made low. Compared to the case where blinds or the like are installed in the room, the solar heat insulation effect is increased.

Further, in the light control device 1 according to the present embodiment, it is possible to suppress heat accumulation on the top floor (for example, the second floor in the case of a two-story house).

Furthermore, in the light control device 1 of the present embodiment, heat can be shielded and the transparency of the field of view can be adjusted, and the light control member 2 can be substituted for a lace curtain. Moreover, deterioration of furniture can be reduced by controlling so that sunlight does not hit furniture according to the direction of solar radiation.

In the light control device 1 of the present embodiment, the light control member 2 is a roofing material 2d in which the transmittance with respect to sunlight is reversibly changed.
