As depicted in figs. 1 and 2, the embodiment of the present invention additionally provides a kind of air-conditioning, and described air-conditioning includes that compressor, described air-conditioning can also include above-mentioned temperature-control circuit.
Below by micro-chip processor U1 be micro-chip processor IC4013, comparable chip U2 be second pair of comparable chip LM393, comparable chip U3 be the 3rd pair of comparable chip LM393 and voltage stabilizing chip U4 for voltage stabilizing chip IC 431 as a example by, the operation principle of temperature-control circuit is described:
nullThere is provided the burning voltage of 2.5V to the electrode input end VIN2+ of second pair of comparable chip LM393 and the negative input VIN3-of the 3rd pair of comparable chip LM393 by voltage stabilizing chip IC 431，Indoor temperature is gathered by described critesistor NTC1，When indoor temperature is less than the temperature threshold of unlatching air-conditioning，The resistance of described critesistor NTC1 is big resistance，Thus，Voltage after described resistance R6 and resistance R7 series connection is less than 2.5V，Thus，Voltage after described resistance R6 that the positive pole input pin VIN3+ of the 3rd pair of comparable chip LM393 collects and resistance R7 series connection is less than 2.5V，The output pin VOUT3 of the 3rd pair of comparable chip LM393 is in low level，Thus，The output pin VOUT3 of the 3rd pair of comparable chip LM393 is the voltage less than 2.5V by exporting the voltage of the negative pole input pin VIN2-to second pair of comparable chip LM393 after diode D2，Thus，The voltage of the output pin VOUT2 of second pair of comparable chip LM393 is high voltage，Thus，The voltage of the emitter stage that the output pin VOUT2 of second pair of comparable chip LM393 is connected to NPN type triode Q1 by resistance R9 is high voltage，The voltage at the resistance R7 two ends that the base stage of NPN type triode Q1 collects is low-voltage，Thus，NPN type triode Q1 does not turns on，The voltage that the base stage of described PNP type triode Q2 being connected with the colelctor electrode of NPN type triode Q1 collects is high voltage，Simultaneously，The transmitting of described PNP type triode Q2 extremely high voltage，Described PNP type triode Q2 does not turns on，The compressor being connected with the colelctor electrode of described PNP type triode Q2 does not works，I.e. do not rotate.
In like manner, if indoor temperature is higher than the temperature of the temperature threshold opening air-conditioning, described negative tempperature coefficient thermistor NTC1 resistance step-down is low resistance, thus, voltage after resistance R6 that the positive pole input pin VIN3+ of the 3rd pair of comparable chip LM393 collects and resistance R7 series connection is high voltage, thus, the output pin VOUT3 output HIGH voltage of the 3rd pair of comparable chip LM393, thus, the output pin VOUT2 of second pair of comparable chip LM393 exports low-voltage, the voltage at the divider resistance R7 two ends that the base stage of NPN type triode Q1 collects is high voltage, NPN type triode Q1 turns on, thus, the base stage of PNP type triode Q2 is low-voltage, PNP type triode Q2 turns on, compressor rotates, in running order；Along with indoor temperature raises, compressor rotary speed speeds, and along with indoor temperature reduces, compressor rotary speed slows down.
nullWhen indoor temperature is again less than the temperature threshold of unlatching air-conditioning，Voltage after resistance R6 that the positive pole input pin VIN3+ of the 3rd pair of comparable chip LM393 collects and resistance R7 series connection is low-voltage，Thus，The output pin VOUT3 of the 3rd pair of comparable chip LM393 exports low-voltage，Due to storage capacitor C2 storing electrical energy，The negative input VIN2-of diode D2 and second pair of comparable chip LM393 is still within high voltage，NPN type triode Q1 and PNP type triode Q2 are still within conducting state，Compressor continues to keep work，When the electric energy of electric capacity C2 discharges into the voltage of the negative input VIN2-of second pair of comparable chip LM393 less than 2.5V by the negative input VIN2-of second pair of comparable chip LM393，NPN type triode Q1 and PNP type triode Q2 all do not turn on，Compressor quits work.
Described by the function of interactive module can by the temperature-control circuit formed for control chip replace realize, when pressing switch key for the first time, control chip is to the negative pole input pin VIN2-input high level of comparable chip U2, when second time presses switch key, control chip is to the negative pole input pin VIN2-input low level of comparable chip U2, it is achieved whether works compressor and is controlled.
In embodiments of the present invention, described compressor control module it is connected with described compressor, gathers indoor temperature and control the duty of described compressor；And also main control module controls described compressor control module according to described indoor temperature so that air-conditioning can automatically turn on according to indoor temperature or close, and then adjust indoor temperature, it is not necessary to user is the most manually opened or closes, and promotes user's experience.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
