Abstract

PURPOSE:To quickly detect an abnormal state by placing an encoder motor as a glass louver turning actuator. CONSTITUTION:When power is supplied to an opening of a window frame in the case it is installed, a glass louver of a motor driven glass louver window is opened and turned by a relay driving circuit 3. After that, when it is fully opened, an encoder motor 6 is locked, an overcurrent having occurred in that time is detected with an overcurrent detection circuit 4, and a glass louver 8 is stopped. Then, when it is fully closed, the encoder motor is locked, and the glass louver is stopped by overcurrent detection. The number of pulses from the full open to the full close mentioned above is counted by a photoencoder 5 of the encoder motor 6 and is stored in an RAM of a micro-computer 2. When an overcurrent is detected within the number of pulses in the time of closed operation, it is decided as an abnormal state, and turning of the glass louver is stopped. According to the constitution, the safety of the motor driven glass louver window is promoted.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to electric glass louver windows. More specifically, this invention
The present invention relates to an electrically operated glass louver window that is excellent in safety and can quickly detect abnormal states as well as fully open/closed states.

0002

[Prior Art] Conventionally, as shown in Fig. 3, for example, a plurality of glass louvers (A) are attached to the window frame opening (A) in windows of houses, etc., and are rotatable in the direction of the arrow in the figure. Electric glass louver windows (c) have been used which have a structure in which the glass louver windows (c) are installed and automatically rotated electrically to open and close.

Regarding this electric glass louver window (c), one is known that has a function of detecting the fully open and fully closed states of the glass louver (a) and automatically stopping the operation of the glass louver (a). ing. An electric glass louver window (c) having such a fully open/fully closed detection function is usually equipped with an overcurrent detection means, for example, as shown in Fig. 4(a), when the glass louver (a) When the motor that rotates the glass louver (a) is fully opened and locked, the overcurrent detection means detects the overcurrent that occurs at this time, sends a motor stop signal, and rotates the glass louver (a).
b) Stop the operation. Further, the fully closed state of the glass louver (a) as shown in FIG. 4(b) is also detected by overcurrent detection using a motor lock, similar to the above-mentioned fully open detection.

[0004] Regarding the electric glass louver window (c), for example, as shown in FIG. In some cases, a safety device has been provided so that this can be detected as an abnormal operation of the glass louver (a) and stopped.

[0005]

[Problem to be Solved by the Invention] However, in electric glass louver windows equipped with this safety device, the abnormality detection is similar to the fully open/closed detection described above, and the motor locks due to fingers (d) or foreign objects being caught. This is done by detecting the overcurrent associated with this, so there is a problem in that a considerable load is placed on fingers (d) or foreign objects until an abnormality is detected and the glass louver (a) is stopped. In particular, if your finger (d) gets caught, it is dangerous as there is a risk of injury, and it may also cause a malfunction.

The present invention was made in view of the above circumstances, and provides a safety feature that eliminates the drawbacks of conventional electric glass louver windows and can quickly detect abnormal conditions as well as fully open/closed conditions. The purpose is to provide an electric glass louver window with excellent performance.

[0007]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention is characterized in that an electric glass louver window equipped with overcurrent detection means is provided with an encoder motor as an actuator. We provide electric glass louver windows.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The electrically operated glass louver window of the present invention will be described in more detail below with reference to the drawings. FIG. 1 is a block diagram illustrating the configuration of a drive/control unit for an electric glass louver window according to the present invention.

For example, as shown in FIG. 1, the electric glass louver window of the present invention includes a power supply circuit (1), a microcomputer (2),
A relay drive circuit (3) and an overcurrent detection circuit (4) are provided, and an encoder motor (6) having, for example, a photo encoder (5) is provided as an actuator for rotating the glass louver.

For example, to explain the fully open/fully closed/abnormality detection of an electric glass louver window by the drive/control unit having the above configuration, as shown in FIG. 2, (a) first,
When power is turned on, such as during installation in a window frame opening, the glass louver (8) of the electric glass louver window (7) is opened by the relay drive circuit (3) illustrated in FIG. When fully opened, the encoder motor (6) is locked, and the overcurrent detection circuit (4) detects the overcurrent generated at this time and stops the glass louver (8).

(b) Next, the closing operation is started. When fully closed, the glass louver (8) stops due to overcurrent detection by the motor lock similar to the above. The number of pulses from fully open to fully closed is counted by the photo encoder (5) of the encoder motor (6) and stored in the RAM or the like built in the microcomputer (2).

In the electric glass louver window of the present invention, overcurrent detection of the electric glass louver window (7) is performed based on the number of pulses stored in this manner. That is, during the opening/closing operation of the glass louver (8), if an overcurrent is detected by the overcurrent detection circuit (4) at the number of pulses stored in advance when the power is turned on, it is determined that the glass louver (8) is fully open/closed.
Stop the rotation of the glass louver (8).

On the other hand, if an overcurrent is detected within the number of pulses during the closing operation, it is determined that there is an abnormality and the glass louver (8
) to stop its rotation. In this way, by using the number of pulses in normal operation as an index for abnormality detection, for example,
As shown in (c), if a finger (9) or a foreign object gets caught in the gap between the glass louvers (8), quickly remove the glass louver (8) without applying any load to the finger (9) or the foreign object. It can be stopped. The safety of the electric glass louver window (7) is improved and breakdowns can be prevented. In this case, it is possible not only to stop the glass louver (8) but also to reverse it to an opening operation.

Furthermore, even if an overcurrent is detected within the number of pulses during the opening operation, the glass louver (8) can be stopped and reversed in the same manner as during the above-mentioned closing operation. Of course, the invention is not limited to the above examples. It goes without saying that various aspects are possible with respect to details such as the circuit configurations of the power supply circuit, relay drive circuit, and overcurrent detection circuit, and the structure and configuration of the microcomputer and encoder motor.
