However, the embodiments described below are illustrative of one preferred embodiment of the present invention, and examples of such embodiments are not intended to limit the scope of the present invention. The present invention can be variously modified without departing from the technical idea thereof.

FIG. 1 is a block diagram showing a functional configuration of an internal configuration of a power-saving receptacle according to the present invention. FIGS. 2A and 2B are external perspective views illustrating an external shape of the power-saving receptacle shown in FIG.

As shown in FIG. 1, the power-saving receptacle according to the present invention includes a plug 10 for receiving AC power from external wiring, a relay 20, an outlet terminal 30 for supplying power to an external electronic device, A relay driving part 40 for driving the relay 20, a voltage detecting part 50 for detecting a voltage between the plug 10 and the receptacle terminal 30, A display unit 80 for outputting information related to the power-saving receptacle, a data memory (not shown) for storing power-saving receptacle-related information 90, and a control unit 100. As shown in FIG.

The plug 10 functions to supply power (AC) input from an external wiring to an electronic device coupled to the receptacle terminal 30. [

The relay 20 is connected between the plug 10 and the receptacle terminal 30 and electrically connects / disconnects the plug 10 and the receptacle terminal 30 based on a switching signal applied from the relay driver 40. [ So that power input from the external wiring to the plug 10 can be supplied / cut through the receptacle terminal 30. At this time, the relay 20 is configured to continuously maintain the current switching state until the next switching signal is input to the instantaneous one switching signal applied from the relay driving unit 40. [

3A and 3B illustrate the configuration of the relay 20, wherein FIG. 3A shows the engaged state of the relay 20, and FIG. 3B shows the separated state. 3A and 3B, the relays 20 are arranged such that the electromagnets 22 are disposed between the first and second permanent magnets 21a and 21b fixedly arranged so as to face the same polarity, for example, the N pole And the first and second metal plates 23a and 23b are fixed to both sides of the iron core 24 which is formed movably through the center of the electromagnet 22. The first and second switch panels 25a and 25b are disposed on the first metal plate 23a and the electromagnet 22, respectively. At this time, the iron core 24 penetrates through the central portions of the first and second switch panels 25a and 25b. The first switch panel 25a is fixed on an instrument on which the first permanent magnet 21a is disposed and the second switch panel 25b is fixed to the iron core 24. [ That is, the polarity of the electromagnet 22 is changed according to the polarity of the current applied through the first and second terminals P1 and P2 of the electromagnet 22, And the second metal plates 23a and 23b are magnetized to have a specific polarity and are moved to the first direction (A, the first permanent magnet side) or the second direction (B and the second permanent magnet side) And the second switch panels 25a and 25b are turned on / off. Therefore, when the relay 20 is switched to ON state or OFF state based on instantaneous current supply for changing the electrode of the electromagnet 22, even if no current is continuously applied The state of the relay 20 is continuously maintained until switching to another state.

In addition, in FIG. 1, the receptacle terminal 30 may be formed on the side surface of the main body provided with the plug 10 as shown in FIGS. 2A and 2B, or may be formed on the bottom surface or the front surface. 2A and 2B, one receptacle terminal 30 is shown, but two or more receptacle terminals 30 may be provided.

The relay driving unit 40 drives the relay 20 based on the control signal applied from the control unit 100 to switch the second switch panel 25b of the relay 20 in the first direction A, (See FIG. 3B) or in the second direction (see FIG. 3B). More specifically, the relay driving unit 40 drives the relay 20 by changing the polarity of the current to the first and second terminals P1 and P2 of the relay 20. At this time, the relay driving unit 40 switches the state of the relay 20 by applying only the instantaneous current so as to have a specific polarity.

The voltage detecting unit 50 and the current detecting unit 60 are power detecting devices for measuring the amount of power consumption between the plug 10 and the receptacle terminal 30, And a current sensor for measuring the amount of current.

The information input unit 70 includes a power key, a mode selection key, a setting key, and a direction UP / DOWN key. The mode selection key is for selecting an operation mode such as a standby power mode, an auto-off time mode, and a power display mode. The setting key is for setting a current date and time, a display state, and the like.

As shown in FIG. 4, the display unit 80 may display the power and the amount of power detected by the power detector 50 and the current detector 60, the amount of used power and standby power supplied to the electronic apparatus, Information, current date and time, mode information selected by the user, and the like.

The data memory 90 stores various kinds of power-related information including a reference standby power and an accumulated power amount for the electronic equipment, a mode and setting information set in the information input unit 70, and the like.

The controller 100 controls the state of the relay 20 through the relay driver 40 on the basis of the power information applied from the voltage detector 50 and the current detector 60. That is, when the standby power is maintained for a predetermined time or more in a state of being coupled to the electronic device in the receptacle terminal 30, the controller 100 sets the relay 20 to the off state through the relay driving part 40, The power supply from the terminal 30 to the electronic device is automatically interrupted. The controller 100 controls the display unit 80 to display the power information applied from the voltage detector 50 and the current detector 60 and the mode and setting information set through the information input unit 70, .

Next, the operation of the power-saving type receptacle having the above-described configuration will be described.

First, the user connects the plug 10 to an outlet (not shown) located on a wall surface or the like, and a plug (not shown) of the electronic device is coupled to the outlet terminal 30.

In the above state, the power (AC) flowing through the plug 10 flows into the electronic device through the relay 20 and the receptacle terminal 30.

The power between the plug 10 and the receptacle terminal 30 is applied to the voltage detection unit 50 and the current detection unit 60. The voltage detection unit 50 and the current detection unit 60 are connected to the plug 10, Terminal 30 to provide the corresponding information to the controller 100. [0031] At this time, the control unit 100 measures the amount of power consumption and the amount of standby power when the electronic apparatus coupled to the receptacle terminal 30 is used, and registers the amount of power consumption and the amount of standby power in the data memory 90. This can be done after repeating a certain number of times based on the time when the plug of the electronic device is coupled to the receptacle terminal 30. [ In addition, the average standby power amount information regarding the standby power amount may be registered in the data memory 90 at the time of manufacture, or may be arbitrarily set by the user through the information input unit 70. [

The controller 100 determines that the voltage and current supplied from the voltage detector 50 and the current detector 60 are below a certain level and more specifically if the power supplied to the electronic equipment is the standby power level, And controls the relay 20 to be in an off state through the relay 40. That is, the relay driving unit 40 applies current to the P1 terminal and the P2 terminal so that the relay 20 operates in the second direction (B, see FIG. 3B).

Therefore, when it is determined that the electronic apparatus coupled to the receptacle terminal 30 is consuming only the standby power, the power supply to the corresponding electronic apparatus is automatically blocked.

Thereafter, when the user intends to use the electronic device again and sets the ON state by inputting the power key through the information input unit 70, the corresponding information is applied to the control unit 100, The relay 20 is controlled to be turned on via the relay driver 40. [ That is, power is supplied to the electronic apparatus coupled to the receptacle terminal 30. [

In this state, the user drives and uses the electronic device he intends to use. At this time, the controller 100 stores the power information applied through the voltage detector 50 and the current detector 60 in the data memory 90, and displays the amount of power corresponding to the current state through the display unit 80 .

In the present invention, it is also possible to control the operation of the outlet through the remote control.

FIG. 5 is a block diagram showing the internal structure of a power-saving receptacle according to a second embodiment of the present invention. FIG. 5 is a block diagram illustrating a wireless communication unit 110 and wireless communication unit 110 The remote controller 120 may be further provided.

The radio processing unit 110 receives a control signal applied from the remote controller 120 through an antenna, demodulates the control signal, and provides the control signal to the controller 100. [ The control unit 100 controls the operation of the relay 20 through the relay driving unit 40 based on a control signal applied from the radio processing unit 110. [

The remote controller 120 wirelessly transmits the outlet control related information to the wireless processing unit 110. [ 6A, the remote controller 120 includes an input unit 121 including an on / off button, and information corresponding to the input button of the input unit 121 And a radio processing unit for converting the signal into a radio signal and transmitting the radio signal through an antenna. At this time, the remote controller 120 repeatedly transmits the radio signal for the information selected by the user three times, thereby minimizing the reception error in the radio processing unit 110 due to the propagation delay and the like.

6B, the remote controller 120 includes a magnet 122 on the rear surface of the remote controller 120, and the remote controller 120 is attached to a metal product such as a refrigerator or the like, And the loss of the remote controller 120 can be minimized.

In the present invention, when it is determined that the plug of the electronic device is not coupled to the receptacle terminal 30 in the control unit 100 in order to prevent an accident such as an electric shock to the infant, the state of the relay 20 through the relay driving unit 40 The power supply to the receptacle terminal 30 can be cut off.

That is, according to the embodiment, when it is determined that the electronic apparatus coupled to the outlet terminal is in an unused state, the power supply to the electronic apparatus is automatically cut off, so that the consumption of standby power generated in the electronic apparatus can be minimized.

In addition, in the above-described embodiment, power consumption due to relay driving for interrupting / supplying electric power to the receptacle terminal is minimized, thereby reducing power consumption of the product itself, thereby providing more effective power saving effect.

In addition, according to the embodiment, the user can display a real amount of power consumption by displaying and outputting the amount of power consumption to the electronic device, so that the user can awaken the user's awareness of the power consumption.

In addition, according to the above embodiment, it is possible to make the power saving habit of the user more easily by controlling the power supply to the electronic device coupled to the outlet terminal by using the remote control.
