Abstract

PURPOSE:To ensure construction of a motor-driven lighting window device by incorporating a resistance equipped with an offset function to transmit a certain frequency into a lighting window control unit which closes the lighting window when detecting rain by means of a rain sensor, an making it possible to find disconnection of the rain sensor while checking operation of the lighting window. CONSTITUTION:A frequency offset resistance R2 is incorporated into a control unit 2 which drives a motor 9 when recognizing rainfall from lowering of the output frequency of a rain sensor 1 and which cannot open a lighting window by control of a remote controller 10 when operated in response to the output from the rain sensor 1. Even when a connector 3 is disconnected a certain frequency is transmitted from the offset frequency R2 and rain conditions are produced so that when operation of the lighting window is checked the remote controller is not operated. Disconnection of the rain sensor 1 can thus be prevented.

2. Description of the Related Art Conventionally, on a roof portion of a house or the like, an electric daylighting window for automatically opening and closing a window (a) as shown in FIG. The device (a) has been provided. Regarding this electric lighting window device (a), a device provided with a rain sensor (c) as illustrated in FIG. 5 has been provided so far,
If there is rainfall when opening the window (a), rain sensor (c) detects raindrops and can automatically drive the window (a) to close, preventing forgetting to close the window (a). To do.

When such an electric window device (a) with a rain sensor (c) is installed on the roof of a house or the like, first, as illustrated in FIG. 6, they are mutually attached at the time of shipping. The window part (a), the lower frame part (d) and the mounting frame part (e) are separated. Next, as illustrated in FIG. 7, the mounting frame portion (e) is fixed to the roof portion (f) by subjecting the roof portion (f) to a rain treatment. Thereafter, as illustrated in FIGS. 8 and 9, the rain sensor (c) is attached to the lower frame portion (d), and the lower frame portion (d) is fixed to the mounting frame portion (e). At the same time, in order to electrically connect the rain sensor (c) and the control device (g) that controls the opening and closing of the window (a) housed in the mounting frame (e), the leads pulled from both sides. Connect the connector (K) (S) provided at the tip of the line (K) (K).

[0004]

However, in the conventional electric lighting window device with a rain sensor as shown in FIG. 5, for example, when it is installed on the roof of a house, as shown in FIG. Since it is necessary to remove the lower frame part (d) and the mounting frame part (e) from the shipping state once, considering the disconnection of the lead wires (h) and (v), the rain sensor (c)
There is a problem that the control device (g) housed in the mounting frame part (e) cannot be connected in advance at the time of shipping.
Therefore, in the past, the rain sensor (c) and the control device (g)
Is connected at the construction site of the electric lighting window device (a),
A contractor unfamiliar with the electric work must perform the work, and as a result, the user often forgets to connect the rain sensor (c) and the control device (g). If the rain sensor (c) and the control device (ki) are left unconnected, the rain sensor (c) will not operate and the window (a) will not close even if there is rainfall. Rain will fall into the room. Thus, even the electric lighting window device with the rain sensor cannot exert its function.

The present invention has been made in view of the above circumstances, solves the drawbacks of the conventional electric lighting window device with a rain sensor, and prevents forgetting to connect the rain sensor and the control device during construction. It is an object of the present invention to provide an electric lighting window device with a rain sensor that can be used.

[0006]

In order to solve the above problems, the present invention provides an electric lighting window device with a rain sensor for detecting rain by a rain sensor and automatically closing an open window portion by electric drive. In (1), a rain sensor has an oscillator having a frequency offset function that oscillates a signal of a constant frequency when the output signal is not input, and the phase difference between the signal of this oscillator and the rain sensor output signal is monitored. An electric lighting window device with a rain sensor is provided, which is provided with a control device that outputs a rain detection signal based on a phase difference generated by connection and closes a window portion.

[0007]

[Operation] In the electric lighting window device with a rain sensor of the present invention, an oscillator having a frequency offset function for oscillating a signal of a constant frequency when an output signal is not input from the rain sensor is provided and The rain sensor and the control device are not connected because the phase difference of the rain sensor output signal is monitored and the rain detection signal is output based on the phase difference caused by the rain sensor not connected, and the control device that closes the window is installed. When the power is turned on in this state, the rain detection signal is output, the window portion is closed, and the window portion remains closed. In the electric lighting window device with a rain sensor, the rain detection input is prioritized over the opening / closing control input from an operation device such as a remote control transmitter from the viewpoint of preventing forgetting to close it during rainfall. Therefore, as long as the rain sensor is not connected, the opening / closing control input from the operation device such as the remote control transmitter is not accepted. Due to this operation abnormality, it is possible to confirm that the rain sensor has not been connected. At the time of operation check after construction, it is confirmed whether the rain sensor is connected or not.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An electric lighting window device with a rain sensor according to the present invention will be described below in more detail with reference to the accompanying drawings. FIG. 1 is a block diagram exemplifying a circuit configuration of a rain detecting section in an electric lighting window device with a rain sensor according to the present invention.

As illustrated in FIG. 1, the rain detecting portion of the electric lighting window device with the rain sensor has a structure mainly composed of a rain sensor (1) and a control device (2). The control device (2) can be housed, for example, in a mounting frame portion of the electric lighting window device, and is electrically connected to the rain sensor (1) by a connector (3). In this example, the control device (2) includes a PLL (phase lock loop) circuit section (4), a phase difference determination circuit section (5), a CPU (6), a motor drive circuit section (7), and a remote control reception. A circuit section (8) is provided.

The PLL circuit section (4) can take out a change in the output signal from the rain sensor (1) due to rainfall as a phase difference between the signals. The PLL circuit section (4) has an original signal (SIG) which is an output signal of the rain sensor (1).
VCO (Voltage Controlled Oscillator) that generates a synchronization signal
Is provided, and the VCO generation signal generated by this VCO and the original signal (SIG) are compared. When there is rainfall, the output signal of the rain sensor (1) changes abruptly, so that the synchronization between the original signal (SIG) and the VCO generation signal is delayed, and this synchronization delay causes the original signal (SIG) and VCO to be delayed.
It appears as a phase difference between the generated signals. PLL circuit section (4)
Then, the phase difference is monitored, and when the phase difference occurs, the phase difference determination circuit (5) outputs the phase difference as a signal.

The phase difference determination circuit section (5) outputs a rain detection signal to the CPU (6) when the phase difference signal from the PLL circuit section (4) has reached a preset specified phase difference. You can Upon receiving the rain detection signal, the CPU (6) commands the motor drive circuit section (7) to close the window section, and drives the motor (9) and the like to close the window section. This CPU
In (6), in order to prevent forgetting to close the window when it is raining, if there is rain detection input, the remote control transmitter (10)
It is set in advance to give priority to the rain detection input over the opening / closing control input from the operation device such as. Therefore, even if the control signal from the remote control transmitter (10) is received by the remote control receiving circuit (8), the CPU (6) does not receive the control input and the motor is driven so that the window remains closed. Command the circuit section (7). Therefore, in the rain detection state, the window cannot be opened by the operation device such as the remote control transmitter (10).

Further, in the example of FIG.
A frequency offset resistor (R2) is also provided in the L circuit section (4). When the electric lighting window device is turned on, the frequency offset resistor (R2) causes the VCO to oscillate a signal having a constant frequency. When the rain sensor (1) and the control device (2) are not connected to each other and are powered on, and when the resistor (R2) is not present, the original signal (SIG) of the rain sensor (1) is used as illustrated in FIG. ) Is not output, the VCO does not oscillate, and the phase difference between the original signal and the VCO generation signal becomes zero. Therefore, the CPU shown in FIG.
Rain detection is not input to (6) and remote control transmitter (10)
It is possible to freely control the operation of the window with an operating device such as. Therefore, even if the operation check is performed after the installation, the forgetting to connect the rain sensor (1) and the control device (2) is not noticed.

On the other hand, as illustrated in FIG. 1, the resistance (R
2) is provided, the VCO oscillates a signal of a constant frequency even when the original signal (SIG) is not output from the rain sensor (1) when the power is turned on. Therefore, as shown in FIG. A phase difference occurs between (SIG) and the VCO generation signal. As a result, the control device (2) shown in FIG. 1 enters the rain detection state, and the window is closed. Since this phase difference is maintained unless the rain sensor (1) is connected, it is always in the rain detection state and the remote control transmitter (1
Even if you try to control the opening and closing with an operation device such as 0), as described above, the rain detection input has priority over the opening and closing control input.
You cannot open the window. Therefore, when the opening / closing control by the operation device cannot be performed at the time of checking the operation after the construction, the builder easily notices that there is some abnormality. By previously recognizing that the main cause of the operation abnormality is the non-connection of the rain sensor, it is possible to confirm the forgetting to connect at the time of the operation check.

As described above, in the electric lighting window device with a rain sensor according to the present invention, it is possible to confirm that the rain sensor and the control device have been forgotten to be connected due to the inability to control the opening and closing by the operation device such as the remote control transmitter during the operation check. it can. Of course, the present invention is not limited to the above examples. It goes without saying that various aspects are possible in details such as the structure and configuration of the rain sensor and the electric lighting window device, and the circuit configuration of the control device.

As described in detail above, according to the present invention, it is possible to prevent forgetting to connect the rain sensor and the control device when the electric lighting window device with the rain sensor is installed.
