Abstract

The utility model relates to an energy-saving controller, composed of an infrared electric sensor circuit, a temperature sensor circuit, a timer circuit, a monostable time-base circuit, a time delay circuit, a relay circuit, etc. The utility model can control the make and break of air conditioners, according to the indoor temperature and the moving of persons. Consequently the effect of the save energy is obtained. A protection circuit in the inner part can guarantee that the air conditioner can not be started. The utility model can be directly connected with the air conditioner to use. The utility model has the advantage of convenient installation.

Description

Energy-saving controller of air-conditioner

The utility model relates to a kind of energy-conserving product, particularly a kind of idle call energy-saving controller.

At present, air conditioner is entering resident family, office, meeting room etc. in a large number, because the increase of air-conditioning, the waste of energy phenomenon also increases the weight of thereupon, in some public places, because people's awareness of saving energy is also not strong, the phenomenon that air-conditioning is opened round the clock is also very serious, can open air conditioner very soon when people enter air-conditioned room, but the often uncomfortable air-conditioning of turning off when going out air-conditioned room, serious waste power resource.For this reason, Air-conditioner design person has done a large amount of effort on energy-conservation, regulate fan blade, frequency control etc. as reload temperature sensor, infrared tracking, but these devices generally have the cost height, inconvenient shortcoming is installed, especially mounted air-conditioning is reequiped difficulty more.

The purpose of this utility model provides a kind of good energy-conserving effect, and cost is low, energy-saving controller of air-conditioner easy for installation.

The purpose of this utility model is achieved in that a kind of energy-saving controller of air-conditioner, by infrared when releasing infrared circuit that electric transducer, amplifier constitute and being connected with the temperature sensing circuit AND circuit IC2 that constitutes by temperature sensor, amplifier base trigger IC3 one end AND circuit IC2 connect, one end is connected with logic gates IC5, infrared circuit is connected with logic gates IC5 by logic time-delay circuit IC4, relay circuit one end that is made of driver and relay is connected with logic gates IC5, and the other end is connected with air conditioner.Time base trigger IC3 is provided with timer circuit IC1.

Energy-saving controller of air-conditioner provided by the utility model, directly linking to each other with air conditioner during use gets final product, easy for installation; Adopt infrared sensor circuit and the dual control of temperature sensor circuit, good energy-conserving effect, time base circuit IC4 has played the effect of holding circuit, has avoided the Fraquent start of air conditioner, prolongs air conditioner service life.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model functional-block diagram.

Infrared circuit is released electric transducer and amplifier is formed by infrared in the utility model, is responsible for surveying infrared signal; Temperature sensing circuit is made of the temperature sensor amplifier, is responsible for the detected temperatures signal; IC1 is a timer circuit, adopts the TMS3450NL clock chip, is responsible for time preset and handles; IC2 is a gate circuit, adopts nor gate 74Ls32, is responsible for the circuit logic conversion, basic trigger when IC3 is, and base trigger when adopting the NE555 monostable is responsible for the stable and triggering of circuit; IC4 is a logic time-delay circuit, and the base trigger prevents the air conditioner Fraquent start when adopting the NE555 monostable; IC5 is a logic gates, adopts and door 74LS09; Relay circuit is made up of amplifier 9013 and relay 4098, is responsible for air-conditioning power supply is provided.

The utility model course of work is as follows: detect by the infrared electric transducer of releasing whether the someone enters between air-conditioning equipment, when the people enters, sensor is sent induced signal into amplifier and is amplified, and sends into gate circuit IC2 then, at this moment, if in summer, indoor temperature is higher than design temperature, and the IC2 input signal is high level, and output just produces low level, thereby base trigger IC3 work when driving, IC3 is output as high level, and logic time-delay circuit IC4 is in high level at this moment, and input then ends, be output as low level, logic gates IC5 conducting is output as high level, thereby drives relay circuit, make relay closes, air conditioner work; When the people left air conditioning room or temperature and is lower than design temperature, it can be low level that the IC2 input all has a pin, and output is high level then, and IC3 ends, and the IC5 closure makes the relay tripping, and air conditioner quits work.

IC1 is a timer circuit, when it is carried out time preset, it can be to IC3 issue high level signal in preset time, thereby base trigger IC3 conducting gate circuit IC5 when triggering, make relay closes, air conditioner work is when reaching setting-up time, when infrared sensor is not sensed the signal that the people enters yet, just close air conditioner automatically.

In order to prevent the air-conditioning Fraquent start; damage compressor, designed holding circuit in the utility model, mainly constitute by logic time-delay circuit IC4; protection process: when the people leaves Air Conditioning Facilities; infrared sensor is output as low level, and IC2 is output as high level, thereby IC3 is ended; at this moment; because IC2 is a low level, thereby start IC4 work, IC4 is output as high level; IC5 does not end because of the IC3 output low level; but the output high level has guaranteed not tripping of relay, and air conditioner can work on; if but surpass setting-up time (as 30 minutes); still nobody enters Air Conditioning Facilities, and IC4 is automatic cut-off also, the air-conditioning stall.
