[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to at least the angle adjustment of an incident light quantity adjusting piece of a light shielding apparatus main body in an electric shade, such as an electric blind, an electric rain door or an electric curtain, having a light shielding apparatus main body comprising a plurality of incident light quantity adjusting pieces. It is about.

2. Description of the Related Art When the sunlight entering a room is strong, the temperature of the room rises due to the radiant heat of the sun. In such a situation, if the room is cooled, the cooling efficiency is deteriorated. Therefore, when performing cooling, it is common practice to block sunlight by using a light-shielding device such as a blind, a shutter, a curtain, or the like to increase cooling efficiency.

FIG. 4 shows an example of an electric blind which is attached to a window or the like to shield sunlight. In this electric blind, a blind main body 1 as a light shielding device main body attached to a window 2 is formed of a plurality of louver pieces 1a as a plurality of incident light amount adjusting pieces, and a motor 3 as a drive unit controls opening and closing of the blind main body 1 or a louver. The angle of the piece 1a can be adjusted.

The opening / closing control of the blind main body 1 or the angle adjustment of the louver piece 1a is performed by operating a switch provided on an operation unit 4. When the blind body 1 is not used, the louver pieces 1a are folded so as to overlap each other as shown in FIG. 5 (a) so as to be housed in a storage portion formed above the window 2, and when used, FIGS. 5 (b) and 5 (c). Opening / closing is controlled so as to lower to the state shown in FIG. Also, as shown in FIG. 5C, for example, each louver piece 1a is 90 degrees away from the state shown in FIG.
The angle is adjusted to be in a state of being connected closely to each other in a state of being rotated by degrees, that is, a state in which sunlight is completely shielded, or as shown in FIG. 5B, each louver is shifted from the state of FIG. The piece 1a has an inclination, forms a gap between the louver pieces 1a, and the angle is adjusted so that sunlight enters through the gap.

[0005]

By the way, in such a conventional electric blind, in order to prevent the room temperature from unnecessarily rising and to take in sunlight appropriately, the operating unit 4 must be operated each time. It was necessary to manually adjust the angle of the louver piece 1a by using this. However, it is practically impossible to force the user to perform such an operation. At present, the user performs the operation only when the sunshine is strong or weak. For this reason, the room temperature may rise unnecessarily, and the cooling efficiency of the cooling device has been reduced.

Further, if it is not necessary to perform light shielding, if the blind main body 1 is left in a lowered state, the blind main body 1 merely obstructs the field of view and has no meaning, and furthermore, the indoor atmosphere is darkened. There are drawbacks. The present invention has been made in view of the above points, and an object of the present invention is to appropriately take in sunlight, prevent a room temperature from rising, and provide a light shielding device main body when it is not necessary to perform light shielding. It is an object of the present invention to provide a motor-driven light-shielding device that can prevent the light-shielding device from obstructing the visual field.

[0007]

According to the present invention, in order to achieve the above object, a light shielding device main body comprising a plurality of incident light amount adjusting pieces and a drive unit for adjusting at least the angle of the incident light amount adjusting pieces of the light shielding device main body. And a clock unit for measuring the current time indicating the solar radiation angle, a sensor unit for detecting the amount of solar radiation which is the outside temperature and the intensity of sunlight, and an incident light amount adjustment corresponding to the current time.
It is necessary to control the drive unit in accordance with the storage content of the storage unit and the current time to adjust the angle of the incident light amount adjustment piece, and to shield the outside temperature and the amount of solar radiation from the storage unit for storing the angle of the piece. A control unit for causing the drive unit to control the opening and closing of the light-shielding device main body depending on whether or not there is the control unit.
The angle of the incident light amount adjusting piece is controlled to be constant .

[0008]

The present invention has the above-described structure,
Automatically adjusts the angle of the incident light amount adjusting piece according to the current time, that is, the angle of solar radiation, takes in the sun moderately, prevents the indoor temperature from rising, and adjusts the outside temperature and the intensity of the sun Controls the opening and closing of the light-shielding device main body according to a certain amount of solar radiation, and prevents the light-shielding device main body from obstructing the field of view when the outside temperature and the amount of solar radiation do not need to perform light shielding, and for a specific time. Incident light quantity adjustment for each band
By controlling the angle of the piece to be constant, the incident light quantity
There is not much difference compared to the case where it changes continuously according to the angle of incidence.
Despite the ability to adjust the amount of incident light,
The storage capacity can be reduced .

[0009]

1 to 3 show an embodiment of the present invention. In this embodiment, the present invention is applied to an electric blind, and the blind main body 1 includes a plurality of louver pieces 1a.
The opening and closing control of the blind body 1 and the angle adjustment of the louver piece 1a are performed using a motor 3, and the control of the motor 3 is performed by a control device 5. In the case of the present embodiment, a sensor unit 6 provided outdoors to detect the outside air temperature and the amount of solar radiation, which is the intensity of sunlight, is also provided as a configuration of the electric blind.

The control unit 5 includes an input unit 7 for receiving the output of the sensor unit 6, a timer 8 for measuring time, and a louver piece 1 which is at right angles to the solar radiation angle which changes according to the operation of the sun.
a storage unit 9 for storing the angle of a (the angle of the louver piece 1a is referred to as a louver angle in the following description), the outside air temperature and the amount of solar radiation input from the sensor unit 6, and the current time input from the timer 8 A calculating unit 10 for determining the louver angle of the blind main body 1 based on the louver angle stored in the storage unit 9 in accordance with the above, and an output unit 11 for controlling the driving of the motor 2 under the control of the calculating unit 10. It consists of.

The timer 8 is provided to detect the operation of the sun (solar angle) from the current time. In the case of the present embodiment, the control device 5 is built into the control device 5 integrally, but a time measuring device such as an external timer may be used. Here, the relationship between the time and the solar radiation angle is as shown in FIG. 3 (a), and the louver angle which is perpendicular to the solar radiation angle means θ shown in FIG. 3 (b). The storage unit 9 stores the corresponding louver angle.

By the way, strictly speaking, it is possible to continuously vary the louver angle according to the solar radiation angle shown in FIG. 3 (a). It is often meaningless to go strictly. Therefore, in the case of the present embodiment, a method is employed in which the louver angle is controlled to be constant for each specific time period. By doing so, the storage unit 9
Can be reduced, and an effect that is not much different from the case where the louver angle is continuously varied according to the solar radiation angle can be expected.

A sensor unit 6 for detecting the outside air temperature and the amount of solar radiation
Is provided to control the opening and closing of the blind main body 1 depending on whether the outside air temperature and the amount of solar radiation need to perform light shielding. In other words, if it is not necessary to perform light shielding, if the blind main body 1 is left in a lowered state, the blind main body 1 merely obstructs the field of view and does not make sense, and furthermore, there is a drawback that the indoor atmosphere is darkened. Because.
Therefore, in this embodiment, when it is not necessary to perform light shielding,
The blind body 1 is automatically raised.

The operation of this embodiment will be described below with reference to the flowchart of FIG. The electric shading device of this embodiment is operated from 7:00 to 19:00, and from 19:00 to 7:00 of the next day, the blind main body 1 is lowered and completely closed as shown in FIG. 5 (c). The state (louver angle 0 degree) is set. Then, at 7 o'clock, the blind main body 1 is raised as shown in FIG. Then, the sensor unit 6 detects the outside air temperature and the amount of solar radiation, and outputs a sensor output to the control device 5 when both the outside air temperature and the amount of solar radiation exceed the set values.

When this sensor output is input to the arithmetic unit 10 via the input unit 7, the arithmetic unit 10 determines that it is necessary to shade the sun with the blind body 1, and in this case, the blind body 1 From the state of FIG.
As shown in (b), a control output for lowering is output to the output unit 11.
Give to. Thereby, the motor 3 is driven by the output unit 11, and the blind body 1 is lowered.

The sensor unit 6 may input the outside air temperature and the amount of solar radiation directly to the arithmetic unit 10 and the arithmetic unit 10 may determine whether the outside air temperature and the amount of solar radiation are equal to or higher than the set values. When the blind body 1 is lowered as described above, if the louver piece 1a is tilted to some extent (for example, the louver angle is set to 45 degrees) so as not to obstruct the sunshine, the blind body 1 is lowered. It is preferable because it does not darken.

Thereafter, the arithmetic unit 10 controls the louver angle by determining the current time. In the case of this embodiment, once the blind body 1 is lowered, the louver angle is adjusted according to the time thereafter. For example, from 7 to 10 o'clock and from 15:00 to 19 o'clock, the louver angle is 70
11: 00-13: 00, the louver angle is 30 degrees,
At 11:00 and 13:00 to 15:00, the angle is controlled to 45 degrees. That is, when the sunshine increases, the amount of incident light is reduced, and when the sunshine weakens, the amount of incident light is increased.

If the outside air temperature and the amount of solar radiation are below the set values even during the period from 7:00 to 19:00, the bride main body 1 is raised as shown in FIG. Make sure that 1 does not obstruct the field of view. And
After 19:00, the blind body 1 returns to the initial state in which it is lowered and completely closed as shown in FIG. If the opening and closing of the blind body 1 or the adjustment of the louver angle are automatically performed in accordance with the time, the outside air temperature, and the amount of solar radiation in this way, it is possible to prevent the indoor temperature from rising, thereby increasing the cooling efficiency of the cooling device. Further, it is possible to prevent the light shielding device main body from obstructing the field of view when it is not necessary to perform light shielding.

In the above case, only the operation of automatically opening and closing the blind body 1 and controlling the angle of the louver piece 1a has been described. Of course, the opening and closing of the blind body 1 and the louver piece 1a are manually performed by the operation unit 4. The angle can be adjusted. By providing a louver angle setting unit in the operation unit 4, the louver angle in each time zone may be changed to a setting different from that described above. Further, the louver angle setting unit is connected to the control device 5.
, And the electric blind construction company may make adjustments according to the situation of the room.

Further, in the above case, the electric blind has been described. However, even in the case of an electric shutter or an electric curtain, even if the shutter body or the curtain body is formed by a plurality of incident light amount adjusting pieces corresponding to louver pieces. Needless to say, the present invention can be applied.
