る上からは問題であつた。 In the case of electrically operated storm shutters, they cannot be opened or closed automatically in the event of a power outage, making it impossible to evacuate in the event of a fire, etc., so it is necessary to be able to open the shutters manually. For this purpose, as shown in FIG. 4, a rope 11 is connected to the end of a winding roll 7 that winds up the shutter 6, and by pulling the rope 11, the winding roll 7 is rotated and the shutter 6 is opened. , as shown in FIG. 5, a proposal is made in which the handle 8 is rotated and this rotation is transmitted to the reducer 10 via the universal joint 9 to generate a large torque and rotate the winding roll 7. has been done. However, in the former conventional example, when the shutter 6 is opened and closed by a motor, the rope 11 always moves as the winding roll 7 rotates, causing noise, and the rope 11 is easily rubbed, which tends to shorten the life of the rope 11. Furthermore, in an emergency, a large amount of force is required to pull the rope 11 to open the shutter 6, and in an emergency, the shutter 6 cannot be simply opened but closed. In the latter conventional example, a reduction gear 10 is used because of the need to increase torque, so even if the handle 8 is rotated, the winding roll 7
The handle 8 rotates only a little at a time, requiring the handle 8 to be rotated many times, which is time consuming and tiring to operate, and also has the disadvantage that it is difficult to operate the handle 8 in a hurry during an emergency. Therefore, the above conventional example cannot be easily operated by children, etc., and is a problem from the standpoint of ensuring the safety of residents by opening the shutters 6 promptly in the event of a disaster to enable evacuation. It was hot.

The purpose is to ensure the safety of residents.

る。 The electric storm door device of the present invention includes a storage battery 1 for power supply during power outages, a charging circuit 2 that constantly charges the storage battery 1 from a commercial power source 3, and an AC motor 4 that converts the DC of the storage battery 1 into AC to open and close the rain shutters. An inverter 5 whose output frequency is variable while supplying power to the
and a switch unit 15 for opening and closing the shutters.
, a power outage detection circuit 21 and this power outage detection circuit 21
A changeover switch SW ₂ switches the power supply of the AC motor 4 from the commercial power supply 3 to the storage battery ₁ side supplied via the inverter 5 in conjunction with the power outage detection output of the power outage detection output. It becomes effective upon detection and the switch unit 1
The device is characterized in that it is equipped with a control unit 22 that makes the output frequency of the inverter 5 higher than the commercial power frequency by turning on the emergency switch SW ₁ which has priority over the commercial power supply frequency. AC motor 4 which is driven by 3 to open and close the shutters.
In the event of a power outage, the rain shutters can be opened and closed electrically even during a power outage by being driven by the storage battery 1 via the inverter 5. Also, when the emergency switch SW ₁ , which is activated during a power outage, is operated, Since the output frequency of the inverter 5 is higher than the commercial power supply frequency, the shutters can be opened more quickly, and even in the event of a disaster, it is possible to safely escape to the outdoors through a window or the like. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The electric shutter is installed on the bay window 12, and as shown in FIG.
By rotating the shutter, the roll-shaped shutter 6 can be rolled up to open it, or unwound to close it. This AC motor 4
As shown in FIGS. 1 and 3, the power supply is normally driven by a commercial power supply 3, but in the event of a power outage, it is driven by a storage battery 1 built into the emergency power supply 14. There is. Further, in order to control the AC motor 4 and manually open and close the shutter 6, a switch unit 15 and an emergency unit 19 are attached to a wall or the like in the room. The switch unit 15 includes an open button 16 for opening the shutter 6 and a close button 17 for closing it.
A stop button 18 for stopping the shutter 6 midway is provided, and these buttons 1 and 1 are provided inside.
A control circuit for switching the rotation of the AC motor between forward and reverse directions or off according to signals 6, 17, and 18 is built in. Further, the emergency unit 19 is provided with a push button 20 for turning on an emergency switch SW ₁ for opening the shutters 6 at high speed in the event of a power outage, and an indicator lamp LED for indicating the power outage. FIG. 1 shows the electrical circuit. At all times, it is a changeover switch for relay contacts, etc. in the emergency power supply 14.
The SW ₂ is connected to the commercial power source 3 side, and the AC motor 4 for opening and closing the shutter 6 is driven by the commercial power source 3. Further, the opening/closing or stopping of the shutter 6 is operated by a switch unit 15, and a rectified current is supplied to a storage battery 1 in an emergency power source 14 through a charging circuit 2, and electric power is stored therein. . In addition, the indicator lamp LED is off at normal times, and the emergency switch SW ₁ is disabled. The power outage detection circuit 21 detects the commercial power supply 3 by the action of a coil or the like, and when a power outage occurs and the commercial power supply 3 is no longer supplied, the power outage detection circuit 21 immediately supplies current to the indicator lamp LED to light the indicator lamp LED and also controls the control unit. A power outage signal is input to 22. When a power outage signal is input to the control section 22, the control section 22 switches the changeover switch _SW2 to the inverter 5 side. The electricity stored in the storage battery 1 is sent to the inverter 5 through the control unit 22, and the inverter 5 converts the direct current into alternating current, which is approximately equivalent to the commercial power source 3, and supplies the alternating current to the alternating current motor 4. Therefore, even during a power outage, the AC motor 4 can be driven by the storage battery 1, and the shutter 6 can be opened and closed by operating the switch unit 15 as usual. Further, in the event of a power outage, the emergency switch SW ₁ is also activated, and this emergency switch SW ₁ has priority over the buttons 16, 17, and 18 of the switch unit 15. However, if the push button 20 is pressed to turn on the emergency switch SW ₁ during a power outage and the indicator lamp LED is lit, the control unit 22 outputs a control signal to the inverter 5 to increase its output frequency. (For example, in the Kansai region, when the emergency switch SW ₁ is off, the 60Hz signal is 65
At the same time, a control signal is sent to the switch unit 15 to forcibly rotate the AC motor 4 in the opening direction regardless of the setting state of the switch unit 15, and therefore the shutter 6 is rotated at a higher speed and for a shorter time than usual. It was opened in 2013, and even in the event of a power outage in the event of a fire or other disaster, it is possible to safely and quickly escape to the outdoors through a window. Furthermore, when the power outage stops and the commercial power supply 3 is supplied, the power outage detection circuit 21 detects it and turns off the indicator lamp LED, and at the same time switches the changeover switch SW ₂ to the commercial power supply 3 side to return to normal operation, and the storage battery 1 is turned off. The consumed electricity is stored again.
