Description

[Detailed description of the invention] The present invention relates to a power saving device.

There are various types of power saving devices, but all of them are installed immediately after the breaker. Therefore, during installation, it is troublesome to have to disconnect the wiring between the indoor wiring and the breaker, and the work cannot be done by a person who is not qualified as an electrical worker.

Therefore, the present invention aims to provide a power-saving device that can be easily installed by anyone, and is intended to provide a power-saving device that can be easily installed by anyone, and is designed to provide a power-saving device that can be installed at the starting end, both the starting end and the ending end, or the end of the alternating current, voltage, or power waveform. ) A power-saving device that saves power by cutting off the disconnection switch by activating an intermittent switch that interrupts the connection with the load circuit; and Claim 1, wherein the device is of a power strip type. The gist of the invention is the configuration of the power saving device.

To explain the embodiment below, in FIG. 1, l is an outlet, 2 is a plug of the power saving device, 3 is the main body of the power saving device, 4 is a switch for turning on and off the power saving device, 5 is an outlet of the power saving device, 6 is the plug of any electrical appliance, 7
is an electrical appliance.

In FIG. 1, when the plug 2 of the power saving device body 3 is inserted into the indoor power outlet 1, the plug 6 of the electrical appliance 7 is inserted into the outlet 5 of the power saving device body 3, and the power saving device switch 4 is turned on. Power is saved by the action of the circuit inside the power saving device body 3. In this method, the power saving device main body 3 only needs to be connected between the power outlet 1 and the plug 6, just like a power tap, so no special installation work is required.

Therefore, the power saving device can be installed extremely easily.

Moreover, if the power saving device switch 4 is turned off, it can be used like a normal table tap. A plurality of outlets 5 may be installed.Next, a power saving circuit according to the present invention will be explained.

FIG. 2 is a block diagram of an embodiment of the power saving device according to the present invention.
9 is a noise filter, 9 is a voltage detection section, IO is a reference voltage generation section, 11 is a reference voltage variable section, 12 is a voltage comparison section between the voltage detection section 9 and the reference voltage generation section 10, and 13 is an intermittent switch section. Its operation is as follows.

FIG. 3 is a diagram showing the relationship between the voltage across both ends AB of the voltage detection section 9 in FIG. 2 and time. The vertical axis is voltage E, and the horizontal axis is time t.

FIG. 4 is a diagram showing the relationship between the voltage E between both ends AC of the outlet 5 in FIG. 2 and the time t.

When the switch 4 is turned on (in the open state in FIG. 2), a load, such as an electric appliance 7, etc. is connected to the outlet 5, and the plug 2 is connected to an AC power source, the voltage at both ends of the voltage detection section 9, that is, A
The voltage between B changes as a sine wave with time as shown in FIG.

At this time, the voltage comparison section 12 shown in FIG. 2 compares the voltages E1 and E2 from the reference voltage generation section 10 shown in FIG. The unit 13 is instructed to perform intermittent operation.

At to in FIG. 3, the voltage between AB is 0, and at this time, the intermittent switch section 13 is open between BC and closed between AC. After passing to, the voltage increases little by little, and at tl when it changes to the reference voltage E1 output from the reference voltage generator IO, the voltage comparator 12 operates and switches the intermittent switch 13 to open between AC and BC. close the gap. Further, at time t2 when the voltage begins to drop and returns to El, the intermittent switch section 13 is opened between BC and closed between AC. Similarly E
At t3 at the reference voltage of 2, open between AC and close between BC, t4
Now let's say that BC is open and AC is closed. After t5, it is equivalent to to, so it is repeated in the same way.

When such an operation is performed, the voltage across A0, that is, the voltage on the load side changes as shown in FIG. Therefore, between to-tl, t2-t3, t4-t5
The period in between is a rest period, and power corresponding to that period is saved.

In the system shown in Fig. 2, even if the electrical appliance is a load and has an actance (for example, a fluorescent lamp),
Since the waveform shown in Figure 4 does not change, any electrical appliance 7
A substantially constant power saving effect can also be achieved.

A second embodiment diagram of the present invention will be explained.

In the device shown in FIG. 2, the intermittent switch section 13 is turned ON and OFF depending on the value of the voltage of the power supply, but the device shown in FIG. 5 is of a type generally called a phase control method.

&i In Figure 5, 14 is a current detection section, 15 is a delay circuit section, and 16 is a delay control section.Once turned on, the intermittent switch section 13 continues to be on, and when the power passing through it approaches 0, it automatically turns off. It has a structure that turns it off. The current detection unit 14 operates when the current passing through the intermittent switch unit 13 approaches O and the intermittent switch unit 13 is turned off.

To explain the operation of the device shown in FIG. 5, it shows the relationship between the voltage across A3 in the figure and time, with the vertical axis representing voltage E and the horizontal axis t representing time.

In Figure 5, when switch 4 is opened, a pure resistance load is connected to outlet 5, and plug 2 is connected to an AC power source, time t
At the time point θ, the current flowing through the intermittent switch section 13 is O, and the intermittent switch section 13 is OFF. Since it is a pure resistive load, the voltage and current phases are the same. Then, when the next instantaneous current detection section 14 operates, the delay circuit section 15 acts to cause l! Although it has not yet been transmitted to the fr continuation switch section 13, at time t7, that is, after a time delay from t7 to tθ, the intermittent switch section 13 is turned on. Time t8
When this happens, the current becomes 0 again and the intermittent switch section 13 turns OFF.
F, the current detection section 14 operates, and after a certain time delay, the intermittent switch section 13 turns ON, and the operation is repeated. The period after tlO is the same as after t6, and is equal to the time from t7 to t6 and from t9 to t8.

When such an operation is performed, the output voltage of 5, that is, the voltage between A0 becomes as shown in FIG. In FIG. 7, the vertical axis is the voltage P between A0 and the horizontal axis is the time t.

Therefore, the period between t7 and t8 and between t9 and t8 becomes a rest period, and the corresponding power is saved. In this method, if the load has a reactance component, the current and voltage phases will not match, and the waveform shown in Figure 7 will change.
Although it has the disadvantage that the power saving effect varies greatly depending on the electric appliance 7 used, it can be used satisfactorily with incandescent light bulbs, and has the advantage that it can be realized more economically than the method shown in FIG. 2.

A third embodiment of the present invention will be described.

In the system shown in FIG. 2, the intermittent section is turned on and off depending on the value of the voltage of the power supply, but in the system shown in FIG. 8, the power is determined and turned on and off.

A block diagram thereof is shown in FIG. 8, and its appearance is the same as that in FIG. 1.

In FIG. 8, the same parts as in FIGS. 1 and 2 are given the same reference numerals.

In FIG. 9, 17 is a power detection section and 18 is a trigger section.
It shows the relationship between the level in FIG. 8, that is, the value of the output of the power detection section 17, and time, where the vertical axis is the power P and the horizontal axis is the time t.

The operation of this embodiment will be explained with reference to FIGS. 8 and 9.

Connect plug 2 to an AC power source.

When the switch 4 is opened and a pure resistance load is connected to the outlet 5, the output of the power detection section 17 appears as shown in FIG.

In Figure 9, the power is just above O,
The trigger section 18 operates to turn off the intermittent switch section 13.
At the same time, the delay circuit section 15 is operated. At this time, the current becomes O and the power also becomes O, but after that the delay circuit section 15
At time t12, the output from the delay circuit section 15 turns on the intermittent switch section 13 again. The power becomes 0 again at time t13, and when the power slightly exceeds 0, the trigger section 18 operates to turn off the intermittent switch section 13, and turns on the intermittent switch section 13 at time t14, which is delayed for a certain period of time by the action of the delay circuit mt5. Repeat this action.

The process after t15 is the same as after tll.

In this example, the period tll-t12, t13-t14
11, the intermittent switch section 13 is turned off, and the corresponding amount of power is saved.

An example of a case where an inductive load is connected to the circuit outlet 5 shown in FIG. 8 will be explained with reference to FIG. 1O.

When an inductive load is connected, the power factor is not ioo percent and reactive power is generated.

In FIG. 10, similarly to FIG. 9, the intermittent switch unit 13 is turned off during the period t11 to t12 and the period t13 to t14 (section or time), and the corresponding power is saved.

In this case, even if you connect a load that has an actance component, such as an inductive load, it will move to cut the part where the voltage-current product is small, so even if you cut the part where the voltage-current product is small, there will be no major hindrance to the operation of the equipment. Equipment that will not come,
That is, cutting a portion with a small voltage-current product is suitable for a device with a high power saving effect.

Next, FIG. 11 shows an example of application of the present invention. The same numbers as those shown in FIG. is incorporated inside the main body 3.

As explained above, since the power saving device according to the present invention has a form similar to a power strip, no installation work is required, and it has the advantage that anyone can use it immediately. It also has the advantage that depending on the electric appliance 7 used, a corresponding power-saving type can be used.
