Abstract

A standby power shutoff device is provided that includes a switch generating power when turning on and generating an “on” signal using the power, a switching unit generating an “on/off” signal for a product, a power supply unit providing power for function units of the product by receiving an external input power, a power switching unit driven in response to a driving signal to cut off or connect a power supply path for the input power provided to the power supply unit, a control unit generating a control signal for powering off the product in response to an “off” signal from the switching unit, and a driving unit receiving power from the “on” signal from the switching unit, driving the power switching unit to connect the power supply path, and driving the power switching unit to cut off the power supply path in response to a “power off” control signal.

Claims

1. A standby power shutoff device of an appliance/electronic product, the standby power shutoff device comprising:

an on/off switching unit for an on/off operation of the appliance/electronic product that generates an “

on”

signal and an “

off”

signal of the product;

a power unit that provides power for operating internal function units of the product by being provided with external input power;

a power switching unit that is driven by a driving signal and cuts off or connects a power supply path of the external input power supplied to the power unit;

a control unit that generates a control signal for powering off the product by the “

off”

signal generated from the on/off switching unit; and

a driving unit that obtains driving power by on-signal power generated from the on/off switching unit, drives the power switching unit to connect the power supply path, and drives the power switching unit to cut off the power supply path according to a control signal for powering off supplied from the control unit,

wherein the self-generating on/off switch unit comprises a self-generating on/off switch that self-generates power by a mechanical movement of a first knob according to a turning-on control, and generates the “

on”

signal with the power, and that generates the “

off”

signal according to contact-or-separation of the contact point by an operation of the first knob or a second knob provided in addition to the first knob according to a turning-off control.

2. The standby power shutoff device according to claim 1, wherein the on/off switching unit comprises an AC-DC converter that converts AC power generated from the self-generating on/off switch to DC power so that the AC-DC converter provides an “

on”

signal for driving power of the driving unit, and provides an “

on”

signal by delaying the signal output from the AC-DC converter for a predetermined time so that the driving unit drives the power switching unit to connect the power supply path.

3. The standby power shutoff device according to claim 1, wherein the self-generating on/off switch comprises:

a tube-shaped dial knob that has a hollow installed on a plate in a rotatable manner, as the first knob; and

a press knob that is provided in the hollow and can be pressed,

wherein a plurality of permanent magnets for power generation with N poles and S poles alternately arranged is installed inside the dial knob, a coil for power generation is installed in the press knob, and a current corresponding to the “

on”

signal is generated by rotating the dial knob and by an interaction between the permanent magnets and the coil through the coil.

4. The standby power shutoff device according to claim 3, further comprising:

a tact switch that is connected with the press knob,

wherein the contact point of the tact switch is connected when the press knob is pressed, and the “

off”

signal of the on/off switching unit is generated by an operation of the tact switch.

5. The standby power shutoff device according to claim 1, wherein the self-generating on/off switch comprises:

a generator;

a rotatable pinion gear that is connected with a rotor of the generator; and

a stick-shaped press knob that has a rack gear structure connected with the pinion gear, as the first knob,

wherein the pinion gear interlocked with the rack gear structure of the stick-shaped press knob rotates by a movement according to an operation of pressing the stick-shaped press knob to rotate the rotor of the generator so that a current corresponding to the “

on”

signal is generated.

6. The standby power shutoff device according to claim 5, further comprising:

a photo-coupler in which light generated from a light emitting diode is blocked not to be input to a receiving element by a movement of the stick-shaped press knob,

wherein the “

off”

signal of the on/off switching unit is generated according to an output of the photo-coupler.

7. A self-generating on/off switch for an on/off operation of an appliance/electronic product, the self-generating on/off switch comprising:

an on-switch module that self-generates power by a mechanical movement of a first knob according to a turning-on control of the appliance/electronic product, and generates an “

on”

signal with the power; and

an off-switch module that generates an “

off”

signal according to contact-or-separation of the contact point by an operation of the first knob or a second knob provided in addition to the first knob according to a turning-off control of the appliance/electronic product.

8. The self-generating on/off switch according to claim 7, further comprising:

an AC-DC converter that converts the power generated from the on-switch unit to DC power, and

a time delay unit that delays a signal output from the AC-DC converter for a predetermined time.

9. The self-generating on/off switch according to claim 7, wherein the on-switch module comprises:

a tube-shaped dial knob that has a hollow installed on a plate in a rotatable manner, as the first knob; and

a press knob that is provided in the hollow of the dial knob and can be pressed, as the second knob,

wherein a plurality of permanent magnets for power generation with N poles and S poles alternately arranged is installed inside the dial knob, a coil for power generation is installed in the press knob, and a current corresponding to the “

on”

signal is generated by rotating the dial knob and by an interaction between the permanent magnet and the coil through the coil.

10. The self-generating on/off switch according to claim 9, wherein the on-switch module further comprises:

a tact switch that is connected with the press knob,

wherein the contact point of the tact switch is connected when the press knob is pressed, and the “

off”

signal of the on/off switching unit is generated by an operation of tact switch.

11. The self-generating on/off switch according to claim 7, wherein the on-switch module comprises:

a generator;

a rotatable pinion gear that is connected with a rotor of the generator; and

a stick-shaped press knob that has a rack gear structure connected with the pinion gear, as the first knob,

wherein the pinion gear interlocked with the rack gear structure of the stick-shaped press knob rotates by a movement according to an operation of pressing the stick-shaped press knob to rotate the rotor of the generator so that a current corresponding to the “

on”

signal is generated.

12. The self-generating on/off switch according to claim 11, wherein the off-switch module comprises:

a photo-coupler in which light generated from a light emitting diode is blocked not to be input to a receiving element by a movement of the stick-shaped press knob,

wherein the “

off”

signal of the on/off switching unit is generated according to an output of the photo-coupler.
