Detailed description of the invention

Fig. 1 is the circuit diagram of the utility model.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, a kind of intelligent energy-saving electric appliance, including for ac commercial power voltage to be become the direct current that circuit can be used The Switching Power Supply of low-voltage, for the sensor of temperature collection information, the timer for completing Clocked operation and for carrying out The voltage comparator U1 of switch state judgement, the Clocked operation of timer include timing, delay and tapping mode.

The input terminal of the Switching Power Supply connects electric main, output end+connection resistance R1 of Switching Power Supply, capacitor C1, 1 foot of power end of sensor, timer, the foot 5 of voltage comparator U1, relay J and relay J contact J-1, resistance R1's The other end connects the foot 3 of resistance R2 and voltage comparator U1, the other end of the other end connection capacitor C1 of resistance R2, Switching Power Supply Output end-, resistance R3, the other end of timer, 3 foot of ground terminal of sensor, voltage comparator U1 foot 2 and compressor W, The foot 1 of 2 foot of the signal output end connection voltage comparator U1 of sensor, the foot 4 of voltage comparator U1 connect single-pole double-throw switch (SPDT) The non-moving end 2 of S1, the non-moving end 1 of the signal output end connection single-pole double-throw switch (SPDT) S1 of timer, single-pole double-throw switch (SPDT) S1's is dynamic Hold the base stage of connecting triode V1, the other end of the emitter connection resistance R3 of triode V1, the collector connection of triode V1 The other end of relay J, the other end of the other end connect compressor W of the contact J-1 of relay J.

There are two types of battery saving modes for the design tool, the first is temperature control, by sensor temperature collection information and passes through electricity Pressure comparator U1 is judged that the 3 foot voltages of voltage comparator U1 are constant, therefore the variation of its 1 foot voltage will cause output end 4 Single-pole double-throw switch (SPDT) S1 is connected non-moving end 2, can be realized temperature control function by the variation of foot voltage, and temperature is more than or low When a certain value, the 4 foot voltage changes of voltage comparator U1 change the conduction and cut-off state of triode V1, to change relay The movement of device J reaches temperature controlled purpose.
