Description

[0001] Electric power saving and safety outlet [0002]

The present invention relates to an electric power saving and safety outlet, and more particularly, to a power saving and safety outlet, in which a maximum usage target is set in accordance with an allowable power value of various sockets used in all the spaces occupied by a person so that a percentage Electric power saving and safety outlet capable of inducing excessive energy consumption and electric energy saving awareness.

Generally, an outlet or a multi-outlet is an apparatus for distributing electricity including a plurality of outlet openings in one body, and functions to distribute electricity evenly while simplifying wiring. Therefore, usually, one outlet or multi-outlet is used by connecting various kinds of electrical products.

However, since the current capacity used for each product is different, it is not possible to allocate the load to the general user in real life even though it is necessary to check load variation rather than the number of connected products. Therefore, Has occurred.

In addition, although a power distribution board having a breaker for use of each electric power source is provided, it is disadvantageous in that it is vulnerable to sudden power failure, and fire due to overload still occurs.

Therefore, in order to prevent such accidents in advance, it was necessary to develop an outlet that indicates the amount of load current to be applied to the outlet itself, and a technique for achieving this point has been developed.

The above-mentioned prior art will be described in detail with reference to the registered utility model publication No. 20-0333564 (multi-receptacle indicating the load current with respect to the rated capacity, registered on Nov. 2003, 2003). The load current flowing through the multi- And a load current amount display means including a current transformer, a control unit, and a display unit for visually showing a load current amount against the rated capacity. The control section includes a current discrimination circuit and a display driving circuit.

However, the prior art has a problem that the understanding and recognition of the user due to the overloading is small, and the load current amount against the rated capacity is insufficient according to the risk factors according to the step, and as a result, It causes a huge loss due to hardware corruption or all the data disappearing at a moment in the important business process using electronic devices including a computer.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an electric power saving device, The purpose is to visualize the effect. In addition, users can set the target value for power use by themselves and use it, so that it is possible to double the power saving experience through actual experiential learning. In addition, it is possible to increase user's understanding of power saving by generating alarm sound when using more than the target value. In particular, it is possible to cultivate an understanding of proper use by differentiating display color when over power is used, Generation and secondary power cut-off function.

According to the present invention, it is possible to visually and audibly sense the amount of power consumption and generate interest in power saving, thereby raising awareness about the power reserve ratio which is currently a problem in the nation, and thus, it is possible to have a habit of saving energy in daily life , Reduce the power consumption of individual power users, and further reduce power use nationwide. In addition, the reduction of electricity use will lead to a decrease in the amount of carbon dioxide emission. In the case of the national government, export of carbon emission rights to other countries is expected to improve economic benefits and national green environment credibility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a configuration of an electric power saving and safety outlet of the present invention,

FIG. 2 is a view illustrating an electric power saving and safety outlet according to the present invention. Referring to FIG. 2,

An outlet is an apparatus for supplying electricity. In a state in which electricity is supplied to an outlet in which one or more outlet sockets are formed, a user connects the plug to an outlet socket to use electric power. In this case, when electricity is used in the outlet, the CT sensor 10 in the control unit 20 measures the output current, and converts the amount of current flowing into the outlet into a voltage of a predetermined signal level width, Is input to the comparator 210 which compares the output amount with a reference value.

The reference value at this time is measured by the maximum usable power of the power used in the outlet. Further, a person skilled in the art will be able to set various reference values in measuring the reference value of the outlet, so that further explanation will be omitted.

After comparing the voltages output from the comparator 210, the amplifiers 220 amplify the signals to a large level so that the amount of voltage can be processed through the signal amplifiers 220, The processor 230 calculates the amount of voltage in the form of an analog signal and converts it into a digital signal.

The amount of the voltage converted into the digital signal is output from the display 240 to the percentage number indicator 241 from the minimum use amount 0% of the outlet to 100% of the maximum usage amount.

At this time, when the power of the outlet is used, the amount of voltage used is compared and compared with the maximum usable amount, the on-off indicator 242 indicates 0 to 50% of the blue light 22, 50 to 90% , And 90 ~ 100% is red light (24).

When the voltage at the outlet is equal to 100% of the maximum usable power at the microprocessor 230 when the voltage is being processed by the comparator 210, the buzzer 250 sounds an alarm and an error " Please confirm." Is generated in the sound output unit 25.

The safety actuator 260 constitutes a safety operation unit and the relay 261 of the safety actuator 260 receives the buzzer warning from the voice output unit 25 via the blocking control unit 26 of the controller, The time to be blocked is adjusted and the time to be interrupted by the variable timer 221 through the signal amplifier 220 is applied to the relay 261 to adjust the set value.

If the variable timer 221 of the signal amplifier 220 completes the time after the buzzer 250 is generated for the time designated by the user at the relay 261, the power controller 262 of the safety actuator 260 is turned on at the outlet Shut off the incoming power.

When a warning sound is generated in the buzzer 250 due to an abnormal power supply such as a short circuit, a short circuit or a short circuit, and a warning sound and a voice are output from the sound output unit 25, the user disconnects the power supply by arbitrarily extracting the power supply, If the faulty power supply is resolved, it will be restored within 100% and normal use will be possible.

The buzzer 25 generates a warning sound and if the user does not have a cut-off time exceeding the variable timer 221, the power control unit 262 is operated to automatically cut off the power of the outlet, Thereby preventing a fire accident caused by a short circuit.

When the user turns off the power source and the power source is returned to a stable state within the maximum usage amount of 100% of the comparison unit 210, the microprocessor 230 confirms the power state of the power controller 262, And the socket is automatically restored to its original state.

It is possible to set a usable amount of electric power for each outlet when the user uses the electric power by using the outlet, and to display the usage amount of each of the loads in percentage (%) on the constant display display unit 21, The multi-color indication lamp (27) is installed for the use of each outlet so that the user can know the power consumption, and by using the color conversion of the display lamp, a circuit for the power consumption amount for each predetermined interval is built- Indicate the degree of risk of power usage relative to the usage of the distinct load.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, And the like. Accordingly, such modifications are deemed to be within the scope of the present invention, and the scope of the present invention should be determined by the claims of the present invention.
