Hereinafter, a standby power cutoff device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a block diagram of a standby power cut-off device according to an embodiment of the present invention.

As shown in FIG. 1, the standby power cut-off device according to the exemplary embodiment of the present invention may include a power supply circuit 110, a power supply 111, a load 112, a first three-way switch 120, and a second three-way switch. 130, the main control unit 101 and the switch control information supply means 102 is configured.

The power supply 111 is connected in series with the load 112 to supply power to the load 112. In addition, the load 112 is provided with the first three-way switch 120 and the second three-way switch 130 is connected in series, the power supply according to the switching of the first and second three-way switch 130 The on / off of the circuit 110 is optionally determined. Specifically, the first three-way switch 120 may be selectively connected to the first terminal 121 and the second terminal 122 in accordance with the switching, the second three-way switch 130 is the third terminal in accordance with the switching 131 and the fourth terminal 132 may be selectively connected. In addition, the first terminal 121 and the fourth terminal 132 are electrically connected, and the second terminal 122 and the third terminal 131 are electrically connected. Accordingly, when the second three-way switch 130 is connected to the fourth terminal 132 when the first three-way switch 120 is connected to the first terminal 121, the power supply circuit 110 is turned on. And the second three-way switch 130 is connected to the third terminal 131 when the first three-way switch 120 is connected to the second terminal 122, the power supply circuit 110 is turned on. In other cases, that is, when the first three-way switch 120 is connected to the first terminal 121, the second three-way switch 130 is connected to the third terminal 131 or the first three-way switch 120. When the second three-way switch 130 is connected to the fourth terminal 132 when is connected to the second terminal 122, the power supply circuit 110 is turned off.

On the other hand, the first three-way switch 120 is a mechanical switch, the second three-way switch 130 is an electronic switch, its function and role are divided. First, the first three-way switch 120 is a hard switch (not shown) provided in the electronic device is operated when an external physical force is applied, for example, when the user presses in a slide or push method It is switched from the first terminal 121 to the second terminal 122 or from the second terminal 122 to the first terminal 121. In this case, the switching from the first terminal 121 to the second terminal 122 or vice versa may vary according to the switching state of the second three-way switch 130. That is, it may be turned on or off depending on the state of the second three-way switch.

In this way, the first three-way switch 120 is switched on / off according to the physical operation of the user.

Next, the second three-way switch 130 is controlled according to an external remote signal such as a signal generated from the switching control information supply means 102, for example, a remote control signal, for example corresponding to the power off When the remote control signal is input to the electronic device, the second three-way switch 130 switches from the third terminal 131 to the fourth terminal 132 or from the fourth terminal 132 to the third terminal 131. do. At this time, as in the switching of the first three-way switch 120, the second three-way switch 130 also has a third terminal according to the switching state of the first three-way switch 120 to turn off the power supply 111 Switching from 131 to the fourth terminal 132 or switching from the fourth terminal 132 to the third terminal 131 is performed.

The main controller 101 and the switching control information supply means 102 are provided to implement the second three-way switch 130 to be selectively switched according to the remote control signal. The switching control information supply means 102 may be a remote control signal receiver and may be replaced by a timer, a sensing means, or the like. The timer and the sensing means related description will be described later.

When the switching control information supply means 102 is configured as a remote control signal receiver, the switching control information supply means 102 serves to receive a remote control signal transmitted from an external remote controller, that is, a remote control signal corresponding to power off. The main controller 101 receives a signal from the switching control information supply means 102 or controls the second three-way switch 130 by a timer and a sensing device provided therein.

Meanwhile, the mechanical configuration for implementing the second three-way switch 130 is switched between the third terminal 131 and the fourth terminal 132 may be configured as follows. 2 is a configuration diagram of the driving means of the second three-way switch 130 according to an embodiment of the present invention, Figure 3 is a plan view of FIG.

As shown in FIGS. 2 and 3, the driving means of the second three-way switch 130 includes a driving motor 201, a rotating disc 202, and a contactor 203. The driving motor 201 is directly electrically connected to the main controller 101 and operates when a signal corresponding to power off is applied from the main controller 101. The rotation disc 202 is physically connected to the drive motor 201 and rotates according to the operation of the drive motor 201, and the contactor 203 is the rotation disc via a predetermined connecting member 204. 202 is selectively contacted with the third terminal 131 or the fourth terminal 132 in accordance with the rotation of the rotary disk 202. At this time, the driving motor 201 rotates according to a signal applied from the second three-way switch control unit 103 or the main control unit 101, and rotates only by a predetermined angle, thereby causing the third contact of the contactor 203 to be rotated. Contact to the terminal 131 or the fourth terminal 132 is selectively enabled. That is, the driving motor is switched from the third terminal 131 to the fourth terminal 132 or from the fourth terminal 132 to the third terminal 131 by rotating by a predetermined angle, for example, 180 degrees. .

The driving motor is operable in a state in which the first three-way switch is on, and according to the operation of the driving motor, the second three-way switch is changed in contact to turn off the power, thereby completely shutting off the power. Will be switched to the default state. At this time, since the driving motor is rotated and the power is cut off, the third terminal 131 to the fourth terminal 132 or the fourth terminal 132 to the third terminal 131 cannot be switched. The rotation may be stopped at, so that a capacitor capable of storing a certain amount of current is added between the signal inputs of the driving motor to the third terminal 131 to the fourth terminal 132, or the fourth terminal 132 to the third terminal. It is preferable that the contact is completely changed to the terminal 131.

The second three-way switch 130 implemented by the drive motor is only one embodiment disclosed in the present invention, it can be implemented in a variety of mechanical and electronic methods is not limited thereto.

As described above, the standby power cut-off device according to the embodiment of the present invention has been described. In the above-described embodiment, the operation of the second three-way switch 130 is controlled based on the remote control signal. Alternatively, the sensing means may control the operation of the second three-way switch 130.

In the case of using the timer, the timer is connected to the main control unit 101 and the timer is specified in the state in which the main control unit 101 is configured to apply a signal corresponding to the power-off to the second three-way switch 130 at a specific time. When indicating the time, the main controller 101 applies a signal corresponding to the power-off to the second three-way switch 130 to allow the switching between the third terminal 131 and the fourth terminal 132 to proceed. You can turn off the power supply.

In addition, when the sensing means is used, the main controller 101 applies a power off signal to the second three-way switch 130 when the object is not sensed or detected by the sensing means provided at one side for more than a predetermined time. Can be turned off completely.

The application of the present invention will now be described. First, when the electrical device 110 is off, the user slides or pushes the first three-way switch to turn on the first three-way switch so that the electrical device 110 is turned on and the device is used. It becomes the state that I can.

After that, when the user cuts off the power of the electric device 110 by the remote control, the remote control signal receiving unit 106 receives a signal transmitted from the remote control, and the second three-way switch 130 switches through the main control unit 101. By switching, the power is cut off, and when the electric device is to be operated again later, it is possible to slide or push the first three-way switch again to turn on the first three-way switch. At this time, the power cut off by the remote controller may be selectively switched off by soft switching to cut off the power to the standby state or off by hard switching completely blocked to the standby power. For example, the remote control has a separate hard switching power button in addition to the normal power button so that the general power button can turn off the power to standby power, and the hard switching power button can turn off the standby power completely. Can be implemented. In addition, even if a separate hard switching power button is not provided, the soft power off and the hard power off can be distinguished from the remote controller, and thus the power off method can be determined according to the press time of the power button. . At this time, since the implementation method of the soft power off can be implemented in the same way as the power on / off by the conventional remote control, a description thereof will be omitted.

Standby power blocking method of the present invention that can be implemented by other methods in addition to the remote control provides a variety of functions for the user convenience in the OSD (On Screen Dsiplay) method in the case of a display electric device such as a TV, the hard power off of the OSD menu It can be solved simply by adding a menu. That is, by adding the hard power off method to the timer function or the power off function by the sensing means, which are conventionally implemented, the user can selectively use the hard power off at a specific time or under a specific condition through the OSD menu.
