Description

The air conditioner energy saving device

Technical field

The utility model relates to a kind of energy-saving appliance of air-conditioning.

Background technology

In today that living standard improves day by day, air-conditioning has become one of electrical equipment of each family's indispensability, yet when people's air-conditioning that indulges in luxuriousness to one's heart's desire brings comfortable the time, the electricity charge of great number bring people endless worry again, particularly current some electric power is the area seriously, consume kilowatt-hours more, just increased the possibility of a power cuts to limit consumption; Compressor of air conditioner is operated under 75% the situation in addition, and operating efficiency is the highest, and the round-the-clock operation of compressor not only efficient is not high, and the working life of compressor itself also can be affected.

The utility model content

The purpose of this utility model is to provide a kind of air conditioner energy saving device, makes the outside function of air-conditioning be operated under the desirable duty, to reach energy efficient, prolongs the purpose of the working life of compressor.

For achieving the above object by the following technical solutions:

A kind of air conditioner energy saving device is serially connected on the circuit between inner machine of air-conditioning and the outside machine of air-conditioning, and the air conditioner energy saving device is connected successively by on-off control circuit, step-down rectifying circuit, programmable timing electric circuit, on-off control circuit; Described step-down rectifying circuit is formed by an electric capacity and resistance step-down with by bridge rectifier; Described programmable timing electric circuit is that the CMOS programmable timer/counter CD4541BE chip of standard is formed with the adjusting resistance that is connected each pin, electric capacity and triode switch; Described on-off control circuit comprises a triode Q3, a miniature relay JQC and an AC relay WJQC8.

The utility model is according to the feature of the operating efficiency of the outside machine of air-conditioning, programmable timing electric circuit in the energy-saving appliance is carried out time set, able to programmely decide circuit triggers on-off control circuit action, control the work period of the outside machine of air-conditioning, make it to reach optimum working efficiency, the energy consumption of Jie Yueing simultaneously, the working life that has prolonged outside machine.

Description of drawings

Fig. 1, the utility model circuit connection diagram;

Fig. 2, the utility model internal circuit schematic diagram.

The specific embodiment

Shown in Fig. 1-2, a kind of air conditioner energy saving device is serially connected on the circuit between inner machine of air-conditioning and the outside machine of air-conditioning, and on-off control circuit 1, step-down rectifying circuit 2, programmable timing electric circuit 3, on-off control circuit 1 connect successively; Described programmable timing electric circuit is the CMOS programmable timer/counter CD4541BE chip of standard, adopts the encapsulation of dual inline type 14 pin; Described on-off control circuit comprises a triode Q3, a miniature relay JQC and an AC relay WJQC.

Step-down rectifying circuit 2 is to obtain the DC voltage of a 18V by resistance R 10 step-downs of a capacitor C BB22 and a 1M Ω and by bridge rectifier, and input chip CD4541BE etc. partly is that this voltage is through R ₁₁Carry out obtaining after the step-down DC voltage about 6 volts.

Can find out clearly that from figure the control core is the CMOS programmable timer/counter CD4541BE chip of standard, adopt the encapsulation of dual inline type 14 pin.The adjusting of time is to control by 1～3 pin of this chip with setting, and the setting of time is by R ₁～R ₄Resistance regulate, we carry out alternate cycles at the frequency of oscillation that made full use of the switching characteristic of the triode resistance-capacitance network end that chip is external in addition, are characterized in that peripheral circuit is simple, the timing accuracy height, timing range is wide.

2 and 4 of miniature relay JQC terminates at the colelctor electrode of NPN triode, utilize the switching characteristic control miniature relay adhesive and the release of triode, 5 and 1 is normal open state during release, circuit is an off state, in case 5 communicate with 3 during the miniature relay adhesive, the 220V alternating current inserts by 3 pin by 5 and arrives AC relay WJQC8 pin, makes the WJQC adhesive; Utilize the through and off of WJQC to come the outside machine of air-conditioning is controlled, reach purpose of energy saving.

Claims

1, a kind of air conditioner energy saving device is serially connected on the circuit between inner machine of air-conditioning and the outside machine of air-conditioning, and it is characterized in that: the air conditioner energy saving device is connected successively by on-off control circuit, step-down rectifying circuit, programmable timing electric circuit, on-off control circuit; Described step-down rectifying circuit is formed by a capacitor C BB22 and resistance R 10 step-down with by bridge rectifier; Described programmable timing electric circuit is that the CMOS programmable timer/counter CD4541BE chip of standard is formed with the adjusting resistance that is connected each pin, electric capacity and triode switch; Described on-off control circuit comprises a triode Q3, a miniature relay JQC and an AC relay WJQC8.
