Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention can be connected to electrical equipment such as household appliances and lights that are not equipped with a remote control function in a general household, and can be used to power the electrical equipment from a remote location. This invention relates to a remote control outlet with an added remote control function that enables ON10FF operation.

[Conventional technology]

BACKGROUND ART Conventionally, infrared remote control transmitters attached to televisions, videos, etc., have been used only to switch the dedicated television, video, etc. Conventional examples of this type are well known in home appliances.

Also, recently I set it up in a lighting fixture and started operating it from a distance.
There is a means consisting of a light beam type wireless remote control switch set [referred to as the first conventional example] that can be turned on and off.

Then, there is Japanese Patent Application Laid-Open No. 63-86376 [referred to as the second conventional example].

This is a device in which the receiving section of the outlet unit receives a transmission signal sent from the remote control and controls the relay that opens and closes the power switch of the device connection outlet. It is characterized by being equipped with a selector switch, a memory that stores the read signal in read mode, and a microcomputer that compares the read signal with the signal from the remote control and outputs a control signal to the relay when they match. This is a conset unit.

Furthermore, in the third conventional example, Publication No. 93083 is published.

It consists of a switch element inserted into the electrical circuit of the outlet, a remote control signal detection section that detects the signal from the remote control transmitter, and a switch element operation circuit that opens and closes the switch element according to the output of this signal detection section. This is a remote-controlled outlet characterized by being equipped with.

[Problem to be solved by the invention]

However, in these devices, the pulse code of the transmission signal from the infrared remote control transmitter is fixed, and it is impossible to turn the power ON10FF with the infrared remote control transmitter of other types of electrical equipment that are not dedicated to this. In addition, even in the second conventional example of an outlet that can receive transmission signals from multiple remote controllers, the relay is controlled when the read signal matches the transmission signal from the remote control, so the transmission signal and The receiving means is still 1:1.

Therefore, the present invention not only applies the remote control transmitter that is generally commercially available for the above-mentioned home appliances as a remote control transmitter for remote control operation for this home appliance, but also Remotely control the ON10FF of power supplies for stands, electric fans, lights, etc., through the remote control operation of the remote control transmitter, regardless of the type of remote control transmitter code for remote control operation for this home appliance. The purpose is to provide an outlet that can be used for

[Means to solve the problem]

In order to achieve the above object, the present invention provides an electrical outlet in which an infrared transmission signal transmitted from a remote control transmitter is received by a remote control light receiving unit to control a relay that opens and closes a power switch connected to an electrical device. , a remote control receiver unit receives a pulse code, which is an infrared transmission signal emitted from a remote control transmitter, and converts the received pulse code into a continuous pulse having a constant pulse width regardless of the received pulse code. A multi-vibrator whose conversion time constant can be adjusted, a flip-flop that modulates the output pulse of the multi-vibrator into an ON-OFF signal suitable for relay response, and an output signal of this flip-flop that responds to the electrical equipment. This is a remote control outlet characterized by comprising a relay for turning on and off a power switch, and means for connecting the power switch to an electrical device.

[For production]

Since the present invention is configured as described above, the infrared ray 2 transmission signal emitted from any general-purpose remote control transmitter 1 regardless of its model can be received by a remote control connected to any electrical device. The unit 3 receives the infrared rays 2, and the output of the remote control receiving unit 3 hits the multivibrator 123 at the subsequent stage. While the remote control receiving unit 3 is receiving the infrared 2, the pulse width from the multivibrator 123 is adjusted in a constant continuous manner. The pulse is sent to the next stage flip-flop 10.
9 given, flip-flop 109 is the first multi-by break 1
The input pulse from 23 turns on the power to the electrical equipment, and when the remote control light receiving unit 3 does not receive the infrared rays 2, the multi-by-break 123 stops transmitting and the input to the flip-flop 109 is also eliminated.

However, flip-flop 109 remembers that there was a human power pulse from the first multivibrator 123;
It continues to output an output that turns on the power of relay 6.

Next, it is assumed that the remote control light receiving unit 3 receives the infrared rays 2 again.

With the input pulse from the multivibrator 123 again,
The polarity of the output of the flip-flop 109, which continues to output the output with the first input pulse, is inverted.

Relay 6 is output from this flip-flop 109.
The power is turned OFF, and this inverted output is continued to be stored, thereby holding the relay 6 in the power OFF state.

When the remote control light receiving unit 3 receives the infrared rays 2 again, the previous operation is repeated with the power turned on again.

FIG. 1 is a schematic diagram showing the signal flow and circuit configuration in one embodiment of the present invention.

Any model on the market can transmit the infrared ray 2 signal sent from the remote control transmitter 1, which often emits infrared rays.
The voltage signal is received by a remote control light receiving unit 3 connected to an arbitrary electric device, and the remote control light receiving unit 3 supplies the voltage signal to a circuit 4 that adjusts the pulse width.

Then, the circuit 4 for adjusting the pulse width introduces the continuous pulse of a constant width into the flip-flop 5, and the flip-flop 5 responds to the continuous pulse of the constant width from the circuit 4 for adjusting the pulse width and outputs the power from the output terminal Q. The ON signal continues to be output, and the reception by the remote control light receiving unit 3 stops, and the continuous pulse of a constant width from the pulse width adjustment circuit 4 also follows and stops, but in this memorized power ON state from the flip-flop 5. The relay 6 is continuously energized to keep the power connected to the electrical equipment ON. Next, when the remote control light receiving unit 3 receives the infrared rays 2 from the remote control transmitter 1 again, a continuous pulse of a constant width is introduced into the flip-flop 5 in the same manner as before, the output of the flip-flop 5 is reversed, and this is stored. This outlet is configured so that the power is turned OFF and then repeatedly turned ON when the remote control light receiving unit 3 receives the power again.

The contact piece from 65 is connected to the output terminal 63 or 64 to control power ON10FF to the electrical equipment.
