Unit for power-savings of electric units

The present invention relates to a standby power cut-off device of a multi-tap outlet configuration, and more particularly, to cut off standby power during standby time when not in use to control the power of electric and electronic products, which are common household appliances, and to save power while It is related with the structure which provides the convenience which makes operation unnecessary.

BACKGROUND ART Recently, home appliances that have been widely used are usually used by plugging power cords of a plurality of home appliances into so-called multi-tab outlets having a plurality of outlets attached to a single cord drawn from a wall. This is because there are usually no more than two power outlets drawn on the wall of a home, but most households use three or more home appliances.

Most home appliances, such as TVs, VCRs, refrigerators, audio and cordless telephones, are large in number, and in most homes they are left unplugged into multi-tap outlets even when not in use. do.

This is not only cumbersome to disconnect the cord when not in use, as well as mechanical damage to the cord portion by detaching the power cord from a repetitive outlet, and most of the power strip outlet is left out of reach It is due to the inconvenience that it is too inconvenient to leave it by hand.

Because of this, even if they are unplugged when not in use at home, even if there is more than 10% power saving effect, it is not properly implemented, so the consumption of national standby power is enormous.

In view of these problems, the present applicant has devised a number of standby power saving devices as a source.

However, since the standby power saving device of the source is mostly configured as a separate unit and used in existing home appliances, it occupies space and there was economical waste of having to separately purchase a power strip outlet and a power saving unit.

In addition, by controlling only the home appliances attached to a single outlet, there is a problem that causes an additional generation of costs when applied in a home having a plurality of home appliances.

The exemplary configuration of the standby power saving unit (U) described above can be configured in various ways, and it can be configured as a circuit board (P) inside the housing (1) of a multi-tap outlet having a large number of such sources, but relatively small. The circuit best suited for is disclosed in the present invention.

The standby power saving unit (U) is a level control window (L) that can be adjusted without disassembling the light receiving window (IR) for receiving the infrared sensor 70 for performing the operation described later and the variable resistance of the level controller 40, etc. ) Is preferably provided in the housing 1 as a hole or window.

The circuit configuration of the standby power saving unit U implemented as the block diagram shown in FIG. 1 is as follows.

The standby power saving unit (U) of the present invention interposed between an input line (4) from a wall outlet (not shown) such as a home and a plurality of outlets (2) which is an output to a home appliance,

In order to use as a driving power source of the standby power saving unit (U) itself has a DC converter 10 connected in parallel with the input line (4),

Between the DC converter 10 and each outlet 2 which is an output unit, the following switching device unit is also connected in parallel, and one of the control power lines L1 is driven by the power source obtained from the DC converter 10. SW) has a configuration to be performed.

The DC converter 10 is configured as a conventional AC-DC converter and the switching device SW is a conventional relay switch or triac.

The operating current from the DC converter 10 is connected to the OP amplifier 30 via the DC-DC converter 20. In addition, the level controller 40 is connected between the DC-DC converter 20 and the OP amplifier 30, and the variable load sensor 50 is connected between the DC converter 10 and the OP amplifier 30.
