Abstract
The utility model relates to an energy saving energy automatic switch device which belongs to the field of electric power energy switch control at home, office, guesthouse and hotel. The utility model has the technical proposal that infrared reflection inductors L1 and L2 connected with resistances R4 and R5 form an inducting circuit in electric circuit, resistances R3, R4 and R5 are connected with a single chip unit IC, a triode T connected with the resistance R3 and an electric relay J forms a control execution electric circuit, a usually open contact point J-1 of the electric relay J, which is connected in series between using electricity apparatuses, forms a main power source control circuit, an electric capability C1 connected in parallel with a resistance R1 and connected with a diode D1, an electric capacity C2, the resistance R2, the single chip unit IC, a voltage regulated diode DW2 and an electric capacity C3 forms a power supply power electric circuit. The utility model has the advantages of simple structure and convenient installation, fixed on the needed gate side of the room. A main power source control circuit connected before the power source of an electric appliance is able to shut the power source of an electric appliance, with all the persons in the room leaving, to realize security and save energy.
Description
Technical field
The utility model relates to a kind of economize on electricity recloser in family, office, hotel and hotel's electric power energy switch control field.
Background technology
Present family, office, hotel and hotel all have all multiple-purpose electric appliances, usually need to close one by one when leaving, and forget that sometimes then electrical equipment is also in work.Can dwindle greatly this useful life to electrical equipment, and electric power energy is caused waste.Public places such as office, hotel and hotel particularly, this type of situation happens occasionally.The plug-in card mode is now used in public place such as hotel and hotel, uses inconvenience and card and loses easily.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, in a single day a kind of economize on electricity recloser that can open power supply at automatic disconnection power supply circuit under family, office, hotel and the no one's of hotel the situation when having the people to enter automatically is provided.
Its technical scheme is: infrared external reflection inductor L1, L2 connect resistance R 4, R5 member's sensor circuit in the circuit; Resistance R 3, R4, R5 connect single-chip microcomputer IC; Triode T connects resistance R 3, relay J is formed the control executive circuit; The normally opened contact J-1 of relay J is connected on and forms the main power source control circuit between power supply and the electrical appliance; Capacitor C 1 parallel resistance R1 connects diode D1, capacitor C 2, resistance R 2, single-chip microcomputer IC, voltage stabilizing didoe DW2, capacitor C 3 composition power supply circuits.Parallel diode D2 on relay J.
The utlity model has simple in structure, install additional conveniently, be installed in the door limit, room that needs, before the main power source control circuit is connected appliances power source, can plays with room personnel whole and leave and close the effect of appliances power source, play safety, energy-conservation target.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.IN is the electricity consumption power input among the figure; OUT is a power output end;
Embodiment
Be further described with regard to its operation principle below in conjunction with accompanying drawing:
Infrared external reflection inductor L1, L2 connect resistance R 4, R5 in the circuit; Resistance R 3, R4, R5 connect single-chip microcomputer IC; Triode T connects resistance R 3, relay J is formed the control executive circuit; The normally opened contact J-1 of relay J is connected on and forms the main power source control circuit between power supply and the electrical appliance; Capacitor C 1 parallel resistance R1 connection diode D1, voltage stabilizing didoe DW1, DW2, resistance R 1, R2 form power supply circuit.
After this device energized, single-chip microcomputer IC initialization, triode T is by, not adhesive of relay J, the output of power output end non-transformer.When the people enters the room, because infrared external reflection inductor L1, L2 successively are installed on a limit, infrared external reflection inductor L1, L2 sense human body successively, this moment, single-chip microcomputer IC inside added 1 numeration and output signal through resistance R 3 trigger triode T conductings, relay J work, its contact J-1 closure, power output end OUT has power supply output, electrical appliance electric power starting.When the people walked out the room, infrared external reflection inductor L1, L2 reverse induction were to human body, and this moment, single-chip microcomputer IC inside subtracted 1 numeration.Output signal disappears when the inner numeration of single-chip microcomputer IC is 0, and triode T ends, and relay J quits work, and its contact J-1 disconnects, the output of power output end OUT non-transformer, and the electrical appliance power supply will be closed.Thereby realize the purpose of automatic disconnection power supply electricity.
Claims (2)
1. economize on electricity recloser is characterized in that: infrared external reflection inductor in the circuit (L1, L2) connects resistance (R4, R5) respectively and forms body induction circuit; Resistance (R3, R4, RS) connects single-chip microcomputer (IC); Triode (T) connects resistance (R3), relay (J) is formed the control executive circuit; The normally opened contact (J-1) of relay (J) is connected on forms the main power source control circuit between power supply and the electrical appliance; Electric capacity (C1) parallel resistance (R1) connects diode (D1), voltage stabilizing didoe (DW1), electric capacity (C2), resistance (R2), single-chip microcomputer (IC), voltage stabilizing didoe (DW2), electric capacity (C3) composition power supply circuit.
