Abstract

PURPOSE:To improve function of automatic opening/shutting of a top light and to prevent coming-in of the rain arising from failure in putting the top light back to the state of shutting by a method wherein the top light is made automatically openable when a rain sensor is put in operation, and the top light is enabled automatically to shut on signals for complete shutting and for switching the rain sensor off, or on passage of specified period of time for keeping the state of opening. CONSTITUTION:A window part 3 constituting a window for natural lighting is connected, through an opening/shutting link in pantographic structure, to a frame 2 of a top light 1 provided in a ceiling, and a rain sensor 5 is provided over the face of outer peripheral part of the frame 2. Electrodes are provided in parallel with each other with slight distances kept in between over the surface of the rain sensor 5, and detection of the rain is made by electrification between the electrodes made by the raindrops. A controller 6 for controlling opening and shutting of the top light is arranged in the interior, and signals for opening and shutting operations from an operating switch, signals for detecting the upper and the lower limits from a limit switch 7, signals for detecting the raining from the rain sensor 5 and the like are inputted therein. Then commanding signals for opening and shutting the window part 3 are outputted from the controller, based on judgements made by the inputted signals, and thereby the window part 3 is opened when the rain sensor 5 does not detect the raining and when control for automatic shutting is released during the detection is made by the sensor. Automatic shutting of the window part 3 is made when the controller is switched to complete shutting and the rain sensor 5 is switched off, or on passage of specified period of time for keeping the state of opening.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skylight installed on a ceiling of a house or the like, and more particularly to a skylight opening / closing control device which is electrically operated to open / close.

[0002]

BACKGROUND OF THE INVENTION Generally,
Among skylights that open and close electrically with this kind, there is one that is configured to automatically close the window based on the detection of the rain sensor in order to prevent rain from blowing in when opening, but in such a thing, Even if it rains, opening of the window is restricted until the rain sensor dries. Therefore, it has been proposed today to cancel the automatic closing control to allow the opening of the window when a predetermined operation is performed even when the temporary rain sensor is in an undried state. However, in this case, when returning the released automatic closing control, it may be necessary to perform a predetermined returning operation separately, which may complicate the operation, or if the returning operation is forgotten, the subsequent automatic closing operation is closed. Since the control is invalidated, there is an inconvenience that it is not possible to prevent the blowing of rain even if it rains when the provisional law is released.

[0003]

SUMMARY OF THE INVENTION The present invention was devised with the object of providing a skylight opening / closing control device capable of eliminating these drawbacks in view of the above-mentioned circumstances, and a window portion In the skylight that is provided with an automatic closing control means for automatically closing the window part based on the rain detection by the rain sensor in the opening and closing control part for electrically controlling the opening and closing, the opening and closing control part indicates that the rain sensor is in the detection state. The automatic closing control releasing means for allowing the opening of the window portion and the automatic closing control returning means for returning the automatic closing control based on the switching of the rain sensor to the non-detection state are provided. .. Alternatively, in a skylight in which an opening / closing control unit that electrically controls opening / closing of the window unit is provided with automatic closing control means for automatically closing the window unit based on rain detection by a rain sensor, the opening / closing control unit detects a rain sensor. It is characterized in that an automatic closing control releasing means for allowing the opening of the window portion even in the state and an automatic closing control returning means for returning the automatic closing control based on the full closing of the window portion are provided. .. Alternatively, in a skylight in which an opening / closing control unit that electrically controls opening / closing of the window unit is provided with automatic closing control means for automatically closing the window unit based on rain detection by a rain sensor, the opening / closing control unit detects a rain sensor. An automatic closing control releasing means for permitting the opening of the window even in the state, and an automatic closing control returning means for returning the automatic closing control based on the rain sensor maintaining the detection state for a predetermined time or longer when the window is opened. Is provided. With this configuration, the present invention makes it possible to automate the return of the automatic closing control to remarkably improve the operability and to reliably prevent the rain from being blown in due to forgetting the return operation.

[0004]

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a skylight provided on a ceiling of a house or the like, and a frame portion 2 of the skylight 1 has a window portion 3 forming a daylighting window surface provided with a pantograph type opening / closing link mechanism (not shown). The window portion 3 normally closes the opening of the frame portion 2 to regulate the ventilation, while the window portion 3 allows the ventilation in the opened state raised by the drive of the electric motor 4. All the configurations are conventional.

Reference numeral 5 denotes a rain sensor provided on the outer peripheral surface of the frame portion 2. On the upper surface of the rain sensor 5, electrodes arranged in parallel with a slight gap are formed. Rain detection is performed by turning on electricity via the.

On the other hand, reference numeral 6 denotes an opening / closing control section arranged at an appropriate position on the indoor side, and the opening / closing control section 6 is constituted by using a so-called microcomputer (including CPU, ROM, RAM, etc.). This is an open / close operation signal from an operation switch or a remote controller (infrared remote control device) mounted on a wall, an upper limit detection signal and a lower limit detection signal from the limit switch 7, and a rain detection signal from the rain sensor 5. On the other hand, the operation command signal is output to the motor drive circuit 8 formed in the self-holding circuit based on the determination based on these input signals. That is, a control program for opening / closing control, automatic closing control, and automatic closing recovery control, which will be described later, is written in advance in the ROM (read-only memory) of the opening / closing control unit 6.

In the opening / closing control, the opening operation signal, the closing operation signal and the stopping operation signal are output to the motor drive circuit 8 based on the inputs of the opening operation signal, the closing operation signal and the stopping operation signal. A general opening / closing control routine of outputting a stop operation signal based on a signal input to the limit switch 7 in order to automatically stop the electric motor 4 which operates by self-holding is adopted. The control includes an automatic closing control release routine that turns off the automatic closing control flag based on the input of the operation signal when the rain sensor 5 is ON (rain detection state).

On the other hand, the automatic closing control outputs a closing operation signal to automatically close the window portion 3 when the rain sensor 5 is turned on when the window portion 3 is not fully closed. Prior to executing such an automatic closing routine, first determine the state of the automatic closing control flag, and
When this is ON, the automatic closing routine is executed, while when the automatic closing control flag is OFF, the main routine is immediately returned without executing the automatic closing routine.

Further, in the automatic closing return control, when the window portion 3 is fully closed, when the rain sensor 5 is switched off, and when the rain sensor 5 is opened, it is opened for a predetermined time (the rain sensor 5 requires drying). When the time is exceeded, the automatic closing control released by the automatic closing control releasing routine of the opening / closing control is automatically restored.
That is, when the window 3 is fully closed or when the rain sensor 5 is switched to OFF, the meaning of maintaining the automatic closing control in the released state is lost, and the automatic closing can be performed when it rains again. Therefore, the automatic closing control is automatically restored, and when the opening time in the rain detection state exceeds the predetermined time, it rains again and the rain sensor 5 is delayed in drying. Since it can be determined that the window 3 is closed, the automatic closing control is automatically returned to automatically close the window 3.

In the embodiment of the present invention configured as described above, the opening of the window portion 3 is based on the cancellation of the automatic closing control not only when the rain sensor 5 is OFF but also when the rain sensor 5 is ON. However, the released automatic closing control is
When the window part 3 is fully closed or the rain sensor 5 is switched off, the automatic recovery is performed. Therefore, since it is not necessary to restore the released automatic closing control by a separate operation, it is possible to simplify the operation and remarkably improve the operability. It is possible to surely prevent the problem that the air is blown in.

Furthermore, since the automatic closing control is restored even when the opening in the rain detection state exceeds a predetermined time, even if the temporary automatic closing control is released, if it rains, the window 3 The automatic closing of can be done.

[0012]

In summary, since the present invention is constructed as described above, there are provided automatic closing control means for automatically closing the window portion based on the detection of the rain sensor, and automatic closing control releasing means for releasing the window portion. However, the released automatic closing control automatically returns based on the switching of the rain sensor to the non-detection state. Therefore, it is permissible that the operation for returning the automatic closing control is not necessary and the operability can be significantly improved, or the automatic closing control does not work and rain is blown by forgetting the returning operation. Can be reliably prevented.

Further, even if the automatic closing control is automatically restored based on the full closing of the window portion, the same operational effect can be obtained.

Furthermore, in the case where the automatic closing control is automatically restored when the rain sensor maintains the detection state for a predetermined time or more when the window is opened, the temporary closing automatic closing control is released. If it rains, the windows will be closed automatically. That is, when the rain sensor maintains the detection state for a predetermined time or more, it is judged that the rain sensor has been dried again due to the rain that has fallen again and the automatic closing control is automatically restored. The part is automatically closed to prevent rain from blowing in.
