Abstract
The utility model discloses an energy-saving temperature-controlled electric fan, which comprises a power supply, a temperature sensor, a level contrasting circuit, a switch control circuit and a fan. The energy-saving temperature-controlled electric fan is characterized in that the temperature sensor is connected with the level contrasting circuit; the output end of the level contrasting circuit is connected with the switch control circuit; the switch control circuit achieves turn-on and turn-off for the fan through a contactor; and the power supply supplies power to a system. The energy-saving temperature-controlled electric fan can be turned on or off automatically according to indoor temperature, thereby effectively preventing energy waste and protecting a user from getting chill due to excessively long operation of the fan.
Description
Technical field
The utility model relates to a kind of energy-conservation temperature control fan, particularly a kind of can be according to the electric fan of ambient temperature height recloser.
Background technique
It seems that from the national conditions that China is present electric fan is a kind of most realistic radiator, almost every household all be unable to do without it, and it can help us to expel sweltering heat.Often to the time after midnight, temperature reduces, if fan is also blowing always, the people is caught a cold, and has wasted again but when in use.And the timing function of fan intelligence inadequately, sometimes since day cyclostrophic cold and time be provided with oversize, sometimes because long-time sweltering heat and the time is provided with too short.In addition, when autumn has set in, evening the awfully hot fan that blows in, the temperature of the time after midnight reduces greatly, we are often blown flu by fan.Drive the fan of a whole night like this and both wasted the electric energy increase electricity charge, influence people's health again.
Summary of the invention
The purpose of this utility model provides a kind of energy-conservation temperature control fan, and it can be according to indoor temperature height recloser electric fan, thereby has effectively prevented the waste of the energy, and has avoided the user to fan the chill that causes of a specified duration because of blowing in.
The utility model is to realize like this, a kind of energy-conservation temperature control fan, comprise power supply, temperature transducer, level contrast circuit, ON-OFF control circuit, fan, it is characterized in that: described temperature transducer links to each other with the level contrast circuit, the output terminal of described level contrast circuit is connected with ON-OFF control circuit, described ON-OFF control circuit is by the Push And Release of contactor realization to fan, and described power supply is system's power supply.
Description of drawings
Fig. 1 is a system principle diagram of the present utility model.
Fig. 2 is the utility model embodiment's a circuit diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model discloses a kind of energy-conservation temperature control fan, comprise power supply, temperature transducer, level contrast circuit, ON-OFF control circuit, fan, it is characterized in that: described temperature transducer links to each other with the level contrast circuit, the output terminal of described level contrast circuit is connected with ON-OFF control circuit, described ON-OFF control circuit is by the Push And Release of contactor realization to fan, and described power supply is system's power supply.
Preferable example, as shown in Figure 2, by two groups of alternating current transformers, full bridge rectifier and filter regulator circuit, alternating voltage 220v change into voltage of direct-flow voltage regulation just/negative 9v, each several part power supply in circuit again.
In the present embodiment, temperature transducer adopts AD590, integrated operational amplifier LM358 and 47K multiturn potentiometer and load resistance R2 etc. form the level contrast circuit, make the voltage generation 0V of LM358 output terminal or the variation of these two values of 8.5V, its output termination ON-OFF control circuit, described switching circuit mainly is made up of transistor 9013 and relay J, and it can be according to the high-low level of LM358 output terminal, realize the disconnection and the adhesive of relay, thus the switch of control fan.
In addition, the setting of critical temperature (as 25 ℃) is because AD590 has such performance, when temperature is 0K, electric current also is 0, electric current just increases 1UA when the every rising 1K of temperature (promptly 1 ℃), and then electric current is 0.298mA when room temperature is 298K (promptly 25 ℃), and then the voltage on the load resistance R2 is 2.98V, the resistance value of regulator potentiometer W1 makes the voltage at W1 two ends also be 2.98V, make the in-phase end "+" that is input to LM358, end of oppisite phase "-", level just equates.The critical temperature value of switch fan power just has been set at 25 ℃ like this.Certainly this critical value also can be done corresponding change according to actual needs.
When room temperature is lower than 25 ℃ of setting values, the last electric current of AD590 reduces, voltage on the load resistance R2 just is lower than the 2.98V voltage on the potentiometer W1, makes LM358 in-phase end voltage be lower than the end of oppisite phase level, and then the output terminal level is 0, triode Q1 ends, collector electrode has high level, makes relay two ends level equate that voltage is 0, not adhesive of J like this, thus electric fan is closed.
When room temperature is higher than 25 ℃ of setting values, the last electric current of AD590 increases, voltage on the load resistance R2 just is higher than the 2.98V level on the potentiometer W1, make LM358 in-phase end level be higher than the end of oppisite phase level, then the output terminal level is 8.5V, and electric current is 50MA, triode Q1 conducting, the relay J adhesive, thus electric fan is opened.
The utility model is novel, and simplicity of design can be according to indoor temperature height recloser electric fan, thereby has effectively prevented the waste of the energy, and has avoided the user to fan the chill that causes of a specified duration because of blowing in.
