Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing control device for an electric shutter with a slit, which is installed in a window of a general building or installed in a garage or a warehouse. More specifically, it relates to an indoor / outdoor illuminance difference and a temperature difference. Based on the above, the present invention relates to an opening / closing control device for an electric shutter with a slit, which controls and drives the opening / closing ratio of both the slit and the shutter automatically or manually so that ventilation and lighting can be appropriately maintained.

[0002]

2. Description of the Related Art Shutters of this type are generally made of steel or aluminum and have a slit-like opening (hereinafter simply referred to as "slit") formed in a part of the slat and the slit. Some are not. Those without slits are used only for opening and closing as ordinary shutters or doors, and those with slits are used for adjusting ventilation and lighting in addition to opening and closing similar to ordinary shutters.

Further, for example, Japanese Utility Model Laid-Open No. 63-44994 proposes a window device for driving and opening an electric shutter in association with a temperature detector installed in a room.

[0004]

The window device disclosed in the above publication detects the room temperature and closes the shutter when the temperature falls below a predetermined set temperature, or when the temperature exceeds a predetermined set temperature, the shutter is closed. Since it is a very simple control to open the door, the shutter may open and close at any time of the day and night, and the temperature difference between indoor and outdoor and the illuminance difference are not considered at all, and it is practical for crime prevention. Is something that cannot be offered.

On the other hand, in the case of the above-mentioned shutter with a slit, the ventilation and the adjustment of the light are often relied solely on humans, and it is easy to forget to close or open the slit, which is also a problem in crime prevention.

The present invention has been made to solve the above-mentioned problems, and in particular, the opening and closing ratio is automatically or semi-automatically in consideration of crime prevention and the ventilation and daylighting of the shutter with a slit. It is intended to provide an opening / closing control device for a shutter with a slit, which can be finely controlled.

[0007]

Therefore, according to the present invention, there is provided a slit-equipped shutter which has a slit in a part of a slat and is opened and closed by an electric motor. An illuminance sensor and a temperature sensor for detecting a temperature, and an illuminance difference and a temperature difference detected by each of the sensors are compared with a reference value stored in a storage unit in advance to calculate the open / close ratio of the slat and the slit. A condition determination unit, a control unit that issues a control command to the shutter opening / closing drive unit based on the determination of the condition determination unit, and a shutter opening / closing drive unit that controls the drive of the electric motor based on a signal from the control unit. The opening / closing control device for the shutter with a slit is characterized in that the main configuration, and further, the control drive of the electric motor can be performed by a manual operation. It is designed to so that.

[0008]

In the opening / closing operation example of the shutter with a slit provided with the above control device, for example, it is detected that the indoor / outdoor illuminance detector detects the indoor / outdoor illuminance difference when the outdoor becomes gradually brighter. The dawn mode of the shutter SS is selected by comparing with the reference data stored in the storage unit and judging that it is dawn considering the current time. At the same time, the temperature difference between indoor and outdoor is detected by the temperature detector,
Similarly, the condition determination unit compares the reference data stored in the storage unit to determine whether the outdoor temperature is less than T _L or T _{H, for example.}
If it exceeds the threshold, the normal operation mode of the shutter SS is selected and a signal is sent to the control unit to fully open and close the shutter SS. Further, for example, when the temperature inside the room exceeds the temperature difference ΔT set in advance compared with the temperature outside the room, control is performed so that only the upper slit 2 is opened to improve the ventilation in the room. Send a signal to the department. It should be noted that the values of the outdoor temperatures T _L and T _{H and} the value of the temperature difference ΔT change depending on the season such as day and night, summer and winter, and a plurality of the set values are set according to each weather condition. It is switched appropriately and used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be specifically described below with reference to the drawings. The drawings show an opening / closing structure of a shutter with a slit, which is a typical embodiment of the present invention, and a flowchart for the opening / closing control thereof.

FIG. 1 is a vertical sectional view showing a closed state of a shutter SS with a slit to which the device of the present invention is applied.
Is a slat 1 that is part of the shutter SS component
3 is a cross-sectional view showing a connected state of FIG.

As shown in FIG. 2, the slat 1 to which the present invention is applied has a plurality of slits 2 in the width direction of its connecting portion, and the shutter SS is driven to close by an electric motor 3 as shown in FIG. When the lower end of the shutter SS comes into contact with the lower frame 4, all of the unwound slats 1 are in a fully extended state and the slit 2
Is fully open. When the electric motor 3 continues to operate and the lower end of the shutter SS comes into contact with the lower frame 4, the upper slat 1 is sequentially formed from the lower part of the shutter SS to the upper part of the slit 2 formed in the lower slat 1. While sliding so as to close, the connecting portion of each slat 1 sequentially moves downward to close the slit 2. At this time, when the operation of the electric motor 3 is stopped midway, the lower slit 2 is closed and the upper slit 2 remains open, and the shutter SS stops further descending. Hereinafter, in this specification, a state where only the lower slit 2 is in the closed state is referred to as a “half-open state”. When the electric motor 3 is further closed from this half-opened state, the upper slit 2 is also closed.
As shown in, the shutter SS is completely closed.

When the electric motor 3 is reversed in the opening direction from this closed state, the slats 1 are sequentially pulled up from above the shutter SS, so that the slits 2 start to open sequentially from the upper part, and the lower end of the shutter SS is separated from the lower frame 4. At the stage, as shown in FIG. 4, all the slits 2 are fully opened. Therefore, if the electric motor 3 is stopped before the slit 2 is fully opened, the slit 2 of the shutter SS will be in a half-open state.

A control device (not shown) is installed in the storage box portion of the slit shutter SS, and an illuminance detector 5 for detecting indoor and outdoor illuminance and temperature is provided at appropriate portions inside and outside the room, respectively. A temperature detector 6 is attached. The detectors 5 and 6 are connected to the control device, and the control device is further connected to a drive device (not shown) for the electric motor 3. Further, in this embodiment, time information is input to the control device moment by moment. In addition to the detectors 5 and 6, it is also possible to install a shoji opening signal detection unit for opening and closing shoji in the room. Further, an operation panel (not shown) including a condition setting section, a manual operation section and a display section is installed in the room, and by operating the operation panel, desired conditions for automatic operation and manual operation described later are provided. It is possible to set.

Although not shown, a slat position detector is also attached at an appropriate position. The position of the slat 1 can be detected by detecting the number of revolutions of the electric motor 3 as well as using an ordinary photoelectric sensor, an electromagnetic sensor, a micro switch, or the like.

FIG. 5 is a block diagram of the various detecting units, the control unit, the drive unit and the operating unit. The control unit comprises a storage unit, a condition judging unit and a control unit, and the storing unit sets the conditions of the operation panel. Various desired data are written from the outside through the unit and stored. Naturally, the data stored in this storage unit also includes weather data such as seasons or sunshine hours. Various detection signals of the illuminance and temperature detectors 4 and 5 are sequentially input to one condition determining unit, and the condition determining unit compares the detection data with various condition data written in the storage unit. Then, various conditions (modes) are set and set, and the result is sent to the control unit. The control unit receives various results of the calculation and issues various control commands to the drive unit according to the procedure and other data stored in advance in the storage unit. The drive unit controls and drives the electric motor 3 based on a command from the control unit to open / close the shutter SS.

FIG. 6 shows an example of a flow chart in the condition judging section. According to the figure, the judging section compares the indoor and outdoor illuminance difference and temperature difference based on the meteorological conditions and at the same time sets the time. Considering this, modes a to e related to light and dark and modes A to D related to opening / closing operation of the shutter SS are determined based on the result, and the determination signal is sent to the control unit.

That is, the condition determining section receives a signal from the indoor and outdoor illuminance detectors 5 and at the same time time information,
Any of the daytime mode (mode a), nighttime sleeping mode (mode b), nighttime activity mode (mode c), dawn mode (mode d), and dusk mode (mode e) is determined by determining the illuminance change inside and outside the room and the time. And set once. For example, when it is confirmed that the outdoor illuminance is Lx or more and the time is daytime, the daytime mode (a) is selected and set. Further, for example, when it is confirmed that it is nighttime and the illuminance outside the room is higher than the illuminance inside the room, it is determined that the user is sleeping and the nighttime sleep mode (b) is set.

Simultaneously with these sets, the condition judging unit compares the data from the memory unit in consideration of the information from the temperature detector 6 as well, and in order to determine the opening / closing ratio of the shutter SS, the normal operation mode (mode A), A slit half open mode (mode B), a slit full open mode (mode C), or a slat full close mode (mode D) is selected.

For example, according to the flowchart of FIG.
The condition judging section determines various conditions in the following procedure.
When the outdoor becomes brighter, it is determined that it is dawn considering the time, and the shutter SS is fully opened. Further, for example, when the outdoor temperature is _lower than T _L or higher than T _H , the mode A is set and the shutter SS is set.
A signal is sent to the control unit to open and close all of. Further, for example, when the temperature inside the room exceeds the temperature difference ΔT set in advance compared with the temperature outside the room, control is performed so that only the upper slit 2 is opened to improve the ventilation in the room. Send a signal to the department. It should be noted that the values of the outdoor temperatures T _L and T _{H and} the value of the temperature difference ΔT change depending on the season such as day and night, summer and winter, and a plurality of the set values are set according to each weather condition. It is switched appropriately and used.

Further, according to the illustrated example, the functions of these condition judging sections work only during automatic operation and are locked during manual operation. Therefore, in this embodiment, switching between automatic operation and manual operation is possible.

According to the present embodiment, the following are typical examples of mode condition determination by the condition determining unit during automatic operation. Of course, the present invention is not limited to the following conditions. If the room is brighter than the room at night, the slit 2 should not be opened more than halfway. (→ mode c →
Mode B) In the daytime, when the indoor brightness is lower than the outdoor brightness, set the shutter SS to fully open according to normal operation. (→ Mode a → Mode A) When the room is dark and only the outdoor light is obtained at dawn, the slit 2 is set to the half open state, and the shutter is released beyond that.
Prevent SS from opening. (→ Mode d) If the room is illuminated and it is bright and dawn, the shutter is released.
Set the SS so that it is fully opened. (→ Mode f) At night, whether the room is bright or dark,
In the range of outdoor temperature T _L through T _H, and when the temperature of the outdoor is higher than ΔT than the temperature of the room, the shutter SS
Set so that the slit 2 is fully opened in the closed state. (→ Mode C) Further, when the temperature difference is higher than 0 ° C. and less than ΔT, the slit 2 is set to be in a half-open state. (→ Mode c → Mode B) When the daytime mode of the mode a is set, the normal operation mode A is preferentially selected. When the time is dusk and the outdoor illuminance changes from light to dark, set the shutter SS to be fully closed.
(→ Mode e) FIG. 7 shows an example of a flowchart of the control unit at the time of manual operation, and when the operation is switched to the manual operation, the shutter S.
Full opening / closing of S and full-open / half-open operation of the slit 2 are automatically obtained.

FIG. 7 shows an example of a flowchart for receiving the above-mentioned selection mode information sent from the condition judging section in the automatic operation and determining the drive command to be sent to the driving section in the control section based on the mode information. ing.
That is, here, the start / stop position of the shutter SS is determined based on the mode selected by the condition determination unit and the slat is fully opened or closed, or the opening / closing ratio of the slit 2 is determined, and the signal is sent to the drive unit. Send and drive the drive motor to raise and lower the shutter SS to create the desired indoor conditions.

Of course, the illustrated flow chart example shows only one example of the operation, and various other conditions are generally combined. For example, when the condition judgment unit is in the slit half open mode (Mode B) because the condition judgment unit is still operating during the manual mode, the shutter SS is manually opened. , Once the slit is half-opened, it automatically stops, and in this state, the shutter SS is manually operated again.
It is also possible to control the shutter SS to fully open for the first time after performing a fully open operation or after a predetermined time has passed.These programs should be optimized as necessary. You can

As described above in detail, according to the present invention, the illuminance difference and the temperature difference inside and outside the room are detected in consideration of the time, the season, the weather conditions, etc., and the slits formed on the slats are detected. Since the opening / closing ratio is automatically determined and the shutter is automatically opened / closed based on the determination, not only proper ventilation and daylight can be obtained, but also no problem occurs in crime prevention. Further, since the automatic operation can be switched to the manual operation, the shutter is opened and closed in a desired state even when the automatic operation of the shutter is not satisfied or when the automatic operation cannot be performed for some reason. It is possible.
