The display unit 202 includes a display unit 202, In Fig. 2, arrows in the signal lines connected between the respective constituent blocks indicate the operation flow or power supply of the apparatus.

The noise and surge canceling unit 140 removes the noise included in the power source signal coming from the external power source and the surge signal having a higher voltage than the normal signal. The noise and surge canceling unit 140 removes the noise included in the external power supply signal and the instantaneous generated surge signal to prevent malfunction of the power reduction device 100 and the electric equipment 200, It is possible to prevent breakage.

The internal power supply unit 120 rectifies the AC voltage from the external power supply to generate a DC voltage capable of driving the internal circuit of the power reduction apparatus 100. In addition, the battery backup unit 121 is applied as an internal power assist device to smoothly operate the central control unit even in the event of an instantaneous power failure, so that the auxiliary power is input to the central control unit 110 to maintain the basic control operation.

The load sensing unit 150 senses a current value supplied from an external power source and flowing into the electric device 200 connected to the power reduction device 100. The load sensing unit 150 senses a current flowing into the electric device 200 and transmits the sensing current to the central control unit 110.

When the current value is equal to or larger than the predetermined value, the electric appliance 200 recognizes that a required function, that is, an internal load for cold / hot water, is operating, so that unnecessary power is not turned on and off, Power supply.

When the used device 200 has sufficiently completed its function and the internal load is stopped, the signal generated by the load sensing unit 150 disappears, so that operations such as the operation division mode or the limiting mode are resumed.

The switching unit 160 senses a phase of a signal input from an external power source when the external power source is AC and applies a zero crossing operation in operation of the switching unit 160 to be divided and supplied to the electric device 200 To minimize the inrush current by allowing the AC signal to start at phase 0 degrees.

In the operation split mode, the switching unit 160 divides and outputs an external power supply signal to the electric device 200 when the electric device 200 is in the use time state.

In the limiting mode, the switching unit 160 maintains the power supply when the electric device 200 is changed from the restricted state to the operative state, thereby allowing the electric device 200 to be stably driven.

The controller 110 controls the overall operation of the power reduction apparatus 100. [ The control unit 110 generally comprises a microprocessor and is connected to each component of the power reduction device 100, receives data from each component, and sends control signals to each component to control its operation.

The user can change the operation time condition of the power reduction device 100 by operating the switch part 201 in accordance with the use time period and the unused time period of the using device 200. [

The operation display unit 202 displays an internal operation state of the power reduction device 100. [ The display unit 202 may include a light emitting diode or the like and may be connected to the operation display unit 202 according to whether the power reduction device 100 operates in the standby state of the electric device 200 or in the operating state of the electric device 200. [ ) May be displayed differently.

The operation procedure of the power reduction apparatus 100 of the present embodiment configured as described above will be described.

First, the power reduction device 100 is connected to the electric device 200 and the plug 101 of the power reduction device 100 is connected to an external power source. After the power reduction device 100 is installed as described above, the power reduction device 100 is operated. The operation of the power reduction apparatus 100 can be confirmed through the operation display unit 202.

The power reduction device 100 of the present embodiment divides the use time period of the electric device 200 and the unused time period so that the electric device 200 is used at all when the electric device 200 is not used at all, (Limited mode), the power supplied to the electric device 200 is not completely shut off at the time of using the electric device 200, but the power is periodically supplied in a divided manner Split mode). Such a time zone classification setting can be input and set by the user through the switch unit 201. [

For example, in the case of the cold / hot water purifier, the power supply is periodically supplied to the user in a range that does not hinder the use of the electric device 200. When the internal load of the electric device 200 is on, The power is continuously supplied through the load sensing function of the controller 150 so that the electric device 200 can be driven with a desired performance (load sensing mode).

FIG. 3 is a power waveform diagram of a power reduction apparatus according to an embodiment of the present invention. FIG. 3 (a) is an input waveform for a power reduction apparatus, and waveforms (b), (c) It shows the output waveform from the device.

In the operation division mode, the output of the power reduction apparatus 100 is periodically turned on and off as shown in FIG. 3 (b).

The input signal of the external power supply can generally be an alternating current of 60Hz or 220V. In the absence of the power reduction device 100, such an AC signal enters the electric device 200 as it is and consumes a considerable amount of power even in a time period when the frequency of use is not nearly used.

However, according to the embodiment of the present invention, when the power switching unit 160 is in the operation division mode of the power reduction apparatus 100 in the operation or standby state of the electric apparatus 200, And outputs it to the electric device 200. [

In the limiting mode, the output of the power reduction device 100 goes to the off-output voltage as shown in FIG. 3 (c).

In the load sensing mode, the output of the power reduction device 100 goes to the output voltage of ON while the load is sensed (T1 time) as shown in FIG. 3 (e). When the load detection is completed, it operates again in the split mode or the restricted mode according to the original time zone setting.

4 shows an example of the circuit configuration of the switching unit according to the embodiment of the present invention.

For example, the switching unit 160 of the present embodiment may be configured with a known switching device such as a triac device or a photo-triac device. Accordingly, the mode-specific signal according to the embodiment of the present invention is received from the central control unit 110, and the switching unit 160 controls the power supply from the switching unit 160 based on the zero crossing.

Accordingly, the device of the present embodiment outputs the output immediately when the gate voltage is present, and outputs the output until the gate voltage becomes zero when only one short signal is given. This offers the advantages of faster switching speed and accuracy compared to conventional relay devices. Therefore, a triac element is suitable for outputting an external power supply signal in a constant period in a standby state.

For example, the switching unit 160 receives the operation control signal of the central control unit 110 to control the switching of the triac element, receives the external power signal, c), an AC signal as an external power source is divided and output.

The power reduction device 100 according to the embodiment of the present invention is described as an external device connected to the outside of the electric device 200. However, the present invention is not limited thereto, and may be implemented as an embedded device installed inside the electric device 200 . In the embodiment of the present invention, the load sensing unit 150 of the power reduction device 100 is connected to the output terminal of the noise and surge canceling unit 140. Alternatively, the switching unit 160 and the output terminal unit 210 As shown in FIG.

As described above, it is possible for a person having ordinary skill in the art to improve or change the technical idea of the present invention in various forms. Therefore, the embodiments of the present invention described with reference to the drawings should not be construed as limiting the technical idea of the present invention, and the scope of protection of the present invention is limited only by the matters described in the claims.
