2 to 4, a smart Internet-based smart outlet according to the present invention includes an input / output module 10, a socket 20, a housing H, and an IOT module 50.

The smart outlet according to the present invention is mainly used by being detachably connected to an outlet or a multi-tap installed in a building.

The input / output module 10 receives an external power source and outputs it to a load device.

The input / output module 10 includes a body 11, an input terminal 12 protruding forward of the body 11 and receiving an external power source, a power supply unit 12 provided inside the body 11, And an earth terminal 14 protruding rearward from the body 11. The output terminal 13 is connected to the output terminal 13,

The input terminal 12 is connected to an outlet or a multi-tap installed in the building to receive an external power source (commercial power source), and the output terminal 13 outputs a power input to the plug terminal to be connected, Supply power to the device.

The socket 20 guides the plug terminal of the load device to be stably connected to the output terminal 13 of the input / output module 10.

The socket 20 is formed with a seating portion 21 in which a plug body of the load device is inserted and seated and a plug terminal is connected to the bottom of the seating portion 21 to be connected to the output terminal 13 A through-hole 23 is formed.

A pair of plug terminals are inserted into the bottom of the socket 20 so that the through hole 23 is opened so that the infant pushes the chopsticks into the through hole 23 to prevent an electric accident (29).

The input / output module 10, the socket 20, and the IOT module 50 are coupled to the housing H.

The body 11 and the input terminal 12 of the input / output module 10 are exposed in front of the housing H and the seating portion 21 of the socket 20 is exposed to the rear, The IoT module 50 is built in and protected.

The housing (H) is composed of a front case (60) and a rear case (70) assembled together.

On the inner side of the front case 60 and the rear case 70 which are in contact with each other, hook protrusions 71 and hook grooves 61 for hook type assembling are provided.

The front case 60 is formed with a front exposure hole 62 through which the body 11 and the input terminal 12 of the input and output module 10 are exposed and the rear case 70 is provided with the socket 20, The rear exposure hole 72 is formed so that the seating portion 21 of the display portion 21 can be exposed.

A latching step 65 is formed on the inner rear surface of the front case 60 around the front exposure hole 62 and a rear end of the body 11 of the input and output module 10 is caught by the latching step 65 The wings (15) extend outwardly. Thus, the input / output module 10 inserted into the front exposure hole 62 from the inside of the front case 60 is detached from the front exposure hole 62 because the engagement wing 15 is caught by the engagement step 65, It does not.

A fixing protrusion 67 protrudes from the latching step 65 and a fixing groove 17 through which the fixing protrusion 67 is inserted is formed on the latching blade 15. Thus, the fixing projections 67 are inserted and engaged in the fixing grooves 17, thereby restricting the rotation of the input / output module 10 and being disposed at the positions.

A support step 75 is formed on the inner front surface of the rear case 70 around the rear exposure hole 72 and a support blade 25 supported on the support step 75 at the rear of the socket 20.

The wireless communication unit 53 communicates with the external device 3 (e.g., a smart phone, a tablet, a notebook PC, or the like) through an Internet network to transmit various information of the smart outlet to the external device 3 So that the user can remotely monitor from the outside, and receives the control signal of the external device 3 so that the user can remotely control the smart outlet from the outside.

The driving power supply unit 57 converts the external power input through the input terminal 12 into a constant voltage necessary for driving the IoT module 50 and supplies the converted power to the control unit 52 or the like.

The monitoring unit 56 senses the power consumption supplied to the load device 1 through the output terminal 13.

The monitoring unit 56 determines whether the load device 1 is powered on and whether the load device 1 is turned off and is in a standby state based on the power consumption currently being consumed, do.

The power switch 54 turns on / off the power for driving the IoT module 50. The power switch 54 connects the input terminal 12 and the driving power source 57 and turns on and off the electrical connection so that the driving power source 57 allows the external power to be supplied or cut off to the driving power source 57.

If the plug of the load device 1 is not connected to the smart outlet, the IoT module 50 turns off the IoT module 50, .

The LED 55 displays the operating state of the IOT module 50 in the color of light emitted. For example, it indicates whether the power switch 54 is turned on or off and lights green to indicate that the plug of the load device 1 is connected and the load device 1 is in an inoperative state, And the plug of the load device 1 is connected, the load device 1 is informed that it is in an operating state, and it is illuminated in red to inform that the wireless communication device 53 is in a communication disabled state and the same problem occurs.

The control unit 52 controls the IoT module 50 as a whole.

For example, the control unit 52 transmits information on the on / off state of the blocking unit 51 and the power consumption measured by the monitoring unit 56 to the external device 3 via the wireless communication unit 53 The shutoff unit 51 is turned on / off according to a command signal received from the external device 3, the shutoff unit 51 is turned on / off according to the set time, When the power measured by the monitoring unit 56 is overloaded by more than the reference value, the shutoff unit 51 is turned off, information about the overload is transmitted to the external device 3 to inform it, and the power of the load device 1 is turned off And turns off the main cut-off part 51 to shut off the standby power when it is in the standby state.
