Open / close control means for controlling operation electrically, power supply means for supplying power to the open / close control means, and switch for controlling connection and disconnection of a power supply line for supplying power from the power supply means to the open / close control means And means.
The switchgear opens and closes doorways and windows, or openings such as passages and spaces inside structures in buildings such as buildings, houses, factories, and warehouses. Each operation of opening and closing is operated by an opening / closing control means that is electrically controlled by operating an instruction means for instructing the operation. In the present invention, switch means for controlling connection (on state) and disconnection (off state) of a power supply line for supplying power to the opening / closing control means is provided, and this is performed when the opening / closing body is operated by operating the instruction means. Using the switch means, connect the power supply line (ON state) to supply power, and when the instruction means is not operated, use this switch means to disconnect the power supply line (OFF state) and stop supplying power Let As a result, consumption of standby power and the like is suppressed and power saving is achieved. As an instruction means for instructing the operation to the opening / closing means, an open / close stop switch is applicable, but as other examples, a slat is used to adjust the amount of incident sunlight and the amount of inflow / outflow of air. A switch for rotating a predetermined amount, a switch for slightly opening or closing each slat in an engaged state in order to adjust an opening amount of a slit provided in the slat, and the like are applicable. Furthermore, instead of the switch, a circuit that receives an operation instruction instructed wirelessly from a remote controller or the like and transmits it to the control circuit also corresponds.

In this configuration, the first and second transistor type switch means are used to automatically control connection / disconnection of the power supply line, that is, on / off of power supply.

  According to a fourth feature of the switchgear according to the present invention, in the switchgear according to the third feature, the open / close control means is configured such that the first transistor remains until a predetermined time elapses after the open / close operation of the open / close means is stopped. It is to control the second transistor type switching means so that the type switching means maintains the connection state. In this case, the timing at which the first and second transistor-type switch means disconnects (turns off) the power supply line is set to a certain time after the opening / closing operation is stopped. In addition to this, as a timing of disconnecting (turning off) the power supply line, the power supply line may be disconnected (turned off) after a predetermined time has elapsed since the power supply line was connected (turned on), or the operation by the instruction means You may make it cut off immediately after completion | finish.

  According to a fifth feature of the switchgear according to the present invention, in the switchgear according to any one of the first feature to the fourth feature, the power supply means includes solar power generation means and the solar power supply. There is provided battery means for charging / discharging electric power generated by the photovoltaic power generation means, and control means for supplying electric power generated by the solar power generation means and / or battery means to the open / close control means. Since the solar power generation means generates power only during the daytime, it must be opened and closed only by the power of the battery means during other time periods. Therefore, when solar power generation means and / or battery means are used as power supply means, reduction of standby power is an important issue, and the effect of the present invention that can solve this is extremely great.

  According to the switchgear of the present invention, there is an effect that power consumption can be reduced by suppressing standby power consumption of the switchgear.

The charge controller 161 charges the battery 162 with the electric power generated by the solar panel 15 and monitors the state of the electric power generated by the solar panel 15 according to the weather such as nighttime, cloudy weather, and sunny weather. The driving power is supplied to the control circuit 142 by appropriately adjusting the power of 162. The charge controller 161 is provided with an overcharge protection device for the battery 162. For example, when the generated power of the solar panel 15 is small, such as at night or in a cloudy day, the power is supplied from the battery 162 to clear the battery.
