The sound output means 29 may use a speaker or music box to mechanically output sound.

Next, the operation and effect of the door lock device according to the embodiment of the present invention configured as described above will be described.

First, when explaining the normal operation of the key, when going out, while holding the inner-shaped handle (18) of the L-shape installed protruding to the inner plate 12 in the room and rotated clockwise, not shown like a conventional key device The soft and long melody indicating that the lock is released while the lock projection is coupled to the door frame toward the door lock device of the present invention is output from the sound output means 29, or at the same time the inner handle 18 ) And the color of the light emitting diodes 21 installed in the outer handle 14 are changed (for example, red to green), so that the door can be opened and go out.

As such, when the door is closed after the door is opened and the door is closed, the door locking device protrudes toward the door frame and the door locking device of the present invention is locked, and the soft and long melody is transmitted through the sound output means 29 so that the locking device is locked. At the same time, the color of the light emitting diodes 21 provided in the inner handle 18 and the outer handle 14 is changed (for example, from green to red) and lights up. Subsequently, the light emitting diode 21 which is turned on is turned off when water passes in the locked state.

In the above description, even if the locking device for the door of the present invention holds the inner handle 18 and rotates clockwise, the short and fast melody is repeatedly output from the sound output means 29 when the key is not released normally. By holding the handle 18 and pulling the door toward the interior again, it can be rotated clockwise to release the lock normally, and even if the door lock device of the present invention is not closed, even though the door is closed, it is short and fast. Since the melody is repeatedly output from the sound output means 29 or at the same time, the light emitting diode 21 installed in the inner handle 18 or the outer handle 14 flashes (for example, red blinking light). Of course, it is possible to accurately lock the door lock device of the present invention by closing the door again. .

When the door is closed after entering the room, a soft and long melody is output from the sound output means 29 that the door locking device of the present invention is locked, or at the same time, the inner handle 18 or the outer handle 14 The color of the installed light emitting diodes 21 changes (for example, from green to red) and lights up. Subsequently, the light emitting diode 21 which is turned on is turned off when water passes in the locked state.

In the above description, when the password is incorrectly entered in the key board 28 or the key is inserted into the key insertion hole 16 and turned incorrectly in the clockwise or counterclockwise direction, a short and fast melody is greatly output and informed by the surrounding people.

When all the lights in the room is turned off to sleep at night, the illuminance detection sensor 20 installed in the inner plate 12 detects the illuminance of the room and outputs it to the microprocessor 22, so that the microprocessor 22 When the illuminance of the room is dark compared to the illuminance detection signal detected by the illuminance detection sensor 20 and the reference illuminance data pre-stored in the microprocessor 22, the microprocessor 22 emits a light emission control signal. Since it is output to the light emitting diode driver 24, the light emitting diode driver 24 applies power to the light emitting diode 21 to supply the light emitting diode 21 installed in the inner handle 18 or the outer handle 14. By emitting light, the inner handle 18 or the outer handle 14 made of a transparent or translucent body lights up at a constant brightness.

Therefore, it is installed on the door lock device so that the brightness of the room can be easily found at night, and the light emitting diode 21 is turned on at a constant brightness in the indoor and outdoor when the interior illumination is dark. Not only can you easily find the entrance to the door, but you do not have to worry about getting hurt because the person who wakes up does not have to find a specific location by groping in a dark room or by searching for a specific location.

In addition, when going out at night and returning home, the infrared detection sensor 26 installed in the outer plate 10 detects infrared rays emitted from the human body and inputs an infrared detection signal to the microprocessor 22. The microprocessor 22 applies power to the light emitting diode 21 so that the light emitting diode 21 installed in the outer handle 14 or the inner handle 18 is turned on (for example, white) and emits light.

Accordingly, since the outer handle 14 is made of a high-strength synthetic sheet and is made of a transparent body or a translucent body, the light of the light emitting diode 21 is transmitted to the outside to illuminate the door lock device of the present invention with a specific illuminance, so that the outer plate The key board 28 and the key insertion opening 16 which are provided in 10 can be seen easily.

Thus, even if the warehouse lock is automatically locked or the roof door is automatically locked, it can indicate that there is a person in the warehouse or on the roof, and can easily find a key board or a key insertion slot at night.

In the above description, the illuminance detection sensor 20 detects the illuminance of the room at night, and when it is dark, the light emission control signal output from the microprocessor 22 is supplied to the power output from the LED driver 24. Although the light emitting diodes 21 emit light by way of example, the present invention is not limited thereto. For example, the power of the battery 30 is applied to the light emitting diodes 21 by manually turning on / off the light. It goes without saying that the light emission is included in the concept of the present invention.

In the above description, the door lock device formed by protruding the inner handle 18 of the L-shape to the inner plate 12 has been described as an example, but the present invention is not limited thereto, for example, a cylinder type door. Of course, it can be applied to the lock device.
