Utility model content

The purpose of this utility model is to provide a kind of autonomous suspend mode control circuits of air-conditioner outdoor unit, to solve above-mentioned background When air-conditioning shuts down, outdoor unit is constantly in standby mode in the conventional air-conditioning control method proposed in technology, at any time in waiting room The problem of control instruction that machine is sent, this will greatly increase the stand-by power consumption of air-conditioning.

To achieve the above object, the utility model provides the following technical solutions：A kind of autonomous suspend mode control of air-conditioner outdoor unit Circuit, including power supply U, the positive terminal of the power supply U are in series with single-pole double-throw switch (SPDT) K2, the single-pole double throw Connect reset spring on the plug-in strip of switch K2, two groups of plug-in strip interfaces difference indicating lights connected in series D of the single-pole double-throw switch (SPDT) K2 and Protective resistance R, the protective resistance R are connect with electrical appliance, and the electrical appliance and indicator light D pass through conducting wire and power supply U Cathode connection, capacitor C is parallel on the electrical appliance, is provided with electromagnet on the upside of the plug-in strip of the single-pole double-throw switch (SPDT) K2 One group of binding post of Ya, the electromagnet Ya are connect with the anode of AC power source AC, the cathode and electromagnetism of the AC power source AC Another group of binding post of iron Ya is connect with two groups of binding posts of timing control switch K1 respectively by conducting wire, and the timing controlled is opened The input interface for closing K1 is connect by data line with the output interface of MCU controller.

Preferably, the plug-in strip interface on the plug-in strip of the single-pole double-throw switch (SPDT) K2 and protective resistance R is normally closed setting.

Preferably, the capacitance of the capacitor C is 1000-1500 μ F.

Preferably, the resistance value of the protective resistance R is 1200 Ω -1400 Ω.

Preferably, the voltage of the AC power source AC is 5V.

Compared with prior art, the utility model has the beneficial effects that：The autonomous suspend mode control circuit of the air-conditioner outdoor unit is led to Time-controlled setting is crossed, when not in use, reaches timing and then automaticallys cut off the power, to reduce power consumption.

Detailed description of the invention

Fig. 1 is the utility model power supply schematic diagram.

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, the utility model provides a kind of technical solution：A kind of autonomous suspend mode control circuit of air-conditioner outdoor unit, Including power supply U, the positive terminal of the power supply U is in series with single-pole double-throw switch (SPDT) K2, the single-pole double-throw switch (SPDT) Reset spring, two groups of plug-in strip interfaces difference indicating lights connected in series D of the single-pole double-throw switch (SPDT) K2 and protection are connected on the plug-in strip of K2 Resistance R, the protective resistance R are connect with electrical appliance, and the electrical appliance and indicator light D pass through the negative of conducting wire and power supply U Pole connects, and capacitor C is parallel on the electrical appliance, is provided with electromagnet Ya on the upside of the plug-in strip of the single-pole double-throw switch (SPDT) K2, One group of binding post of the electromagnet Ya is connect with the anode of AC power source AC, the cathode and electromagnet Ya of the AC power source AC Another group of binding post connect with two groups of binding posts of timing control switch K1 respectively by conducting wire, the timing control switch K1 Input interface connect with the output interface of MCU controller by data line.

Wherein, the plug-in strip interface on the plug-in strip of the single-pole double-throw switch (SPDT) K2 and protective resistance R is normally closed setting, the electricity The capacitance of container C is 1000-1500 μ F, and the resistance value of the protective resistance R is 1200 Ω -1400 Ω, the AC power source AC Voltage be 5V.

Working principle：MCU controller is programmed, so that its input for meeting data, output, pre-enter setting and cut The time in power-off source, under the action of reset spring, circuit keeps channel status where electrical appliance, after reaching timing, MCU controller exports timing control switch K1 and controls, and timing control switch K1 closure, AC power source AC provides for electromagnet Ya Alternating current, so that electromagnet Ya generates magnetic field, the lock on the plug-in strip of single-pole double-throw switch (SPDT) K2 and indicator light D under the magnetic force Knife terminals closure, thus closing of circuit where indicator light D, so that indicator light D is lighted, and open circuit where electrical appliance, it is right Circuit plays the role of subtracting consumption, when being needed again in use, being inputted by data to MCU controller so that MCU controller control Timing control switch K1 processed is disconnected, thus electromagnet Ya open circuit, the magnetic field of generation disappears, under the action of reset spring, hilted broadsword The plug-in strip and the plug-in strip interface on protective resistance R of commutator K2, thus closing of circuit where electrical appliance.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
