       Hereinafter, the operation of the recessed outlet capable of controlling power according to the present invention will be described in detail with reference to FIGS. 1 to 4.

       First, the recessed outlet 100 capable of controlling power according to the present invention has a structure similar to that of a known recessed outlet, but as shown in FIG. 2, the liquid crystal display 200 and the operation panel 180 at the front thereof. Is formed, the bottom surface is provided with a space that can be inserted into the PCB mounted circuit portion. Meanwhile, the recessed outlet 100 according to the present invention has the same installation method as that of a known recessed outlet. That is, the electric wire is inserted and fixed in the wire insertion hole (not shown) formed in the back of the main body 101, and then the main body 101 is fixed to the embedding hole formed in the wall surface through the bolt.

       Then, when DC power is supplied from the power supply unit 130 to each component, and DC power is supplied to each component, the microcomputer 230 controls the liquid crystal display 200 to control the "power" of the liquid crystal display 200. Let the symbol "on" appear.

       In this state, when the user inserts the key 103 into the key bundle of the key insertion detection unit 170 formed on the side of the main body 101 and rotates the internal contact, the internal contact is short-circuited and the microcomputer 230 from the key insertion detection unit 170. ) The detection signal is output.

       Then, the microcomputer 230 controls the buzzer sound generator 190 to generate a buzzer sound and displays the unlocked symbol on the liquid crystal display 200 by controlling the liquid crystal display 200. do.

       When the user presses the hour button or the minute button among the buttons 181 of the operation panel 180, the microcomputer 230 controls the liquid crystal display 200 so that the hour or minute display area of the liquid crystal display 200 blinks. In this state, when the user operates the hour and minute buttons to set the current time, the microcomputer 230 controls the liquid crystal display 200 to display the corresponding time in the time display area of the liquid crystal display 200. And save the current set time as time setting data. At this time, the microcomputer 230 increases the time by 1 hour or 1 minute every time the hour or minute button is pressed in the operation panel unit 180, and if there is no input of the button for 5 seconds, the current time is automatically set to the currently set time. Is set.

       In addition, when the user presses the timer button among the buttons 181 of the operation panel 180 in the state where the current operation start time is set, the microcomputer 230 controls the liquid crystal display 200 to cause the “timer” symbol to blink. In this state, when the user sets an operation start time by operating an hour or minute button among the buttons 181 of the operation panel unit 180 and then presses a timer button to end the setting, the microcomputer 230 currently sets the time. Save the time setting data. At this time, the microcomputer 230 increments in units of 1 hour each time the button is pressed once, every time the minute button is pressed once. It increases by 10 minutes, and if there is no button input for 5 seconds, it automatically sets the operation stop time to the currently set time.

       In addition, when the user presses the timer button among the buttons 181 of the operation panel 180 while the current operation start time is set, the microcomputer 230 controls the liquid crystal display 200 so that the "timer" symbol blinks. In this state, after setting the operation stop time by operating the hour or minute button of the button 181 of the user panel panel 180 of the user, press the timer button to end the setting, the microcomputer 230 is the currently set time Save the time setting data.

       Meanwhile, the user may set and release each function with one touch through the set / cancel button in the button 181 of the operation panel unit 180. In addition, when the user pulls out the key 103 while setting both the operation set time, the operation stop time, and the alarm time, the microcomputer 230 recognizes this and controls the buzzer sound generator 190 to extract the key 103. The buzzer is generated as an indication that it is recognized that the control unit 200 controls the liquid crystal display 200 so that the lock-shaped symbol appears on the liquid crystal display 200. At this time, even if the button 181 of the operation panel unit 180 is operated while the key 103 is pulled out, the microcomputer 230 does not recognize the corresponding signal.

       While all the settings are completed, the microcomputer 230 compares the current time with the operation setting time and controls the buzzer sound generator 190 when the current time is 5 minutes before the operation setting time so that the buzzer is generated for a predetermined time and is operated to the user. Informs you that the set time is approaching.

       Then, the microcomputer 230 controls the relay driver 120 to switch the relay when the operation setting time passes. When the relay 110 is switched, the connection line 1 between the commercial power source 110V / 220V and the output terminal 102 is short-circuited to supply commercial power through the output terminal 102.

       In this state, the microcomputer 230 compares the current time with the operation stop time, and if the current time is 5 minutes before the operation stop time, the microcomputer 230 controls the buzzer sound generator 190 to generate a buzzer for a predetermined time so that the user stops the operation time. Announce the approach. Then, the microcomputer 230 controls the relay driver 120 so that the relay 110 is switched when the operation stop time enters. When the relay 110 is switched, the connection line 1 between the commercial power source 110V / 220V and the output terminal 102 is opened to cut off the commercial power supplied through the output terminal 102.

       The microcomputer 230 compares the present time with the notification time and controls the buzzer sound generator 19 when the current time is an alarm time so that the buzzer is generated for a predetermined time.

       Meanwhile, the ground fault detector 220 detects a leakage current of each line 1 detected from the image current transformer 210 and outputs a control signal to the microcomputer 230 when a ground fault occurs. The microcomputer 230 then outputs a control signal to the relay driver to open the relay 110 to protect the electrical device from an electric leakage.

       Meanwhile, when the DC power supplied from the power supply unit 130 is not normally supplied due to a power failure, the power detection unit 160 outputs a control signal to the microcomputer 230 so that each component is operated by the power of the battery 140. The battery charger 150 detects the voltage of the battery 140 and charges the battery 140 using the DC power supplied from the power supply 130 when the voltage drops below a predetermined value.

       Therefore, by supplying and disconnecting power from the outlet itself at the time set by the user, it is possible to cut off the power supplied to the electric device without separately removing the plug from the outlet, thereby preventing unnecessary power consumption and automatically when a short circuit occurs. Electrical equipment can be protected by disconnecting power from the outlet.

As described above, according to the buried type outlet controllable according to the present invention, a user desires by supplying and shutting off power from the outlet itself according to a preset time using a timer provided in the buried outlet itself. In addition to providing convenience to control the power at the same time, and to prevent unnecessary power consumption wasted, and to control the outlet only by inserting a separate key can be operated by children's mischief You can make the operation impossible.
