Description

Technical Field

[0001] This invention belongs to the field of air conditioner socket technology, and specifically relates to an application circuit for an intelligent anti-leakage standby socket for air conditioners. Background Technology

[0002] With the rapid development of the social economy and the continuous improvement of people's living standards, air conditioners have become one of the most common electrical appliances in homes and various public places. Statistics show that as of 2024, the number of air conditioners in China had reached approximately 790 million units, and this number continues to grow. During air conditioner use, the phenomenon of long-term standby mode is very common. Although the standby power consumption of a single air conditioner is usually only 3-5W, seemingly insignificant, the cumulative energy waste is staggering due to the large number of units. Estimating an average of 4W, the annual standby power consumption of air conditioners nationwide could reach approximately 27.68 billion kilowatt-hours, equivalent to the total annual residential electricity consumption of the three northeastern provinces. The resulting energy loss and environmental burden cannot be ignored.

[0003] Currently, most common air conditioner sockets on the market are ordinary power interfaces, which generally lack automatic power-off function in standby mode and cannot cut off the power in time in case of leakage, posing certain safety hazards and energy efficiency management deficiencies. Users often overlook the long-term cumulative power consumption problem because the standby power consumption is small, and at the same time, they lack effective protection for electrical safety.

[0004] To address the aforementioned issues, there is an urgent need for a smart socket application circuit that can monitor the air conditioner's operating status in real time, automatically cut off the power supply during standby, and provide protection in case of leakage. Summary of the Invention

[0005] To address the aforementioned problems, the primary objective of this invention is to provide an application circuit for an intelligent anti-leakage standby socket for air conditioners, thereby resolving the technical issues described above.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: This invention provides an application circuit for an intelligent anti-leakage standby socket for air conditioners. This application circuit is electrically connected to mains power, which includes a neutral wire, a ground wire, and a live wire. The application circuit is also wirelessly connected to an air conditioner remote control. The intelligent anti-overload standby socket application circuit for air conditioners includes: Input terminal, connected to mains power; The output unit includes a socket, which is electrically connected to the neutral wire, ground wire, and live wire; A switching unit, located on the live wire, is used to control the connection and disconnection of the live wire; Standby current detection unit and leakage current detection unit; The power supply unit is electrically connected to the neutral wire and the live wire; The main control unit is connected to the power supply unit, the switching unit, the standby current detection unit, and the leakage current detection unit, respectively. The power supply unit is used to supply power to the switching unit and the main control unit; The infrared remote control unit, connected to the main control unit, is used to receive signals transmitted by the air conditioner remote control. The main control unit is used to detect the voltage of the standby current detection unit in order to control the switching unit to turn on or off; The main control unit is used to detect the voltage of the leakage current detection unit in order to control the switching unit to turn on or off.

[0007] Compared with the prior art, the beneficial effects of the present invention are: First, it significantly saves energy and reduces consumption, resulting in outstanding economic benefits: Through the cooperation of the standby current detection unit and the main control unit, it can accurately identify in real time when the air conditioner enters standby mode (power consumption reduced to an extremely low level) and automatically control the switching unit to cut off the power supply, completely eliminating standby power consumption. For the huge number of air conditioning devices in the country, this can effectively avoid the aforementioned waste of up to tens of billions of kilowatt-hours of standby power annually, saving users considerable electricity expenses, while also playing a positive role in promoting national energy conservation, emission reduction, and the achievement of "dual carbon" goals.

[0008] Secondly, it enhances electrical safety and provides proactive protection: This application integrates a leakage current detection unit, which can continuously monitor leakage anomalies in the power supply circuit. Once a leakage current that may endanger personal safety is detected, the main control unit will immediately drive the switch unit to disconnect the live wire, quickly cut off the power supply, effectively prevent electric shock accidents, make up for the lack of safety protection functions in traditional air conditioner sockets, and add a reliable technical guarantee for electrical safety in homes and public places.

[0009] Third, intelligent automatic control, requiring no user intervention: The entire standby power-off and leakage protection process is intelligently judged and executed automatically by the circuit, without the need for manual plugging / unplugging or additional attention from the user. This not only greatly improves the convenience of use, but also avoids the continuous generation of standby power consumption or the long-term existence of safety hazards due to human forgetfulness, realizing "maintenance-free" intelligent energy management and safety protection.

[0010] Fourth, it boasts high functional integration and a compact, practical structure: integrating standby detection, leakage protection, intelligent control, and power management modules into a single application circuit, achieving dual core values ​​(energy saving and safety). Compared to solutions requiring multiple external independent devices (such as timers and independent leakage protectors), this application design is simpler, lower in cost, easier to install and use, and easier to promote and popularize.

[0011] Furthermore, the main control unit includes a button, a main control chip, and a working indicator light S2. The main control chip has a second pin and a fourth pin. The second pin is connected to the positive terminal of the working indicator light S2 through a resistor R4, and the negative terminal of the working indicator light S2 is grounded. The fourth pin is connected to one end of the button, and the other end of the button is grounded.

[0012] Preferably, the main control chip can be model SC8P062B.

[0013] Furthermore, the power supply unit includes a first input terminal and a second input terminal. Preferably, the voltage of the first input terminal is 12V, and the voltage of the second input terminal is 3.3V.

[0014] Furthermore, the power supply unit also includes a transformer, a power management circuit, a bridge rectifier circuit, a primary stage circuit, and a secondary stage circuit. The power management circuit includes a power management chip, preferably an LP3667B.

[0015] The primary coil of the transformer is connected in sequence to the power management circuit and the bridge rectifier circuit. The bridge rectifier circuit is connected to the live wire and the neutral wire. The secondary coil of the transformer is connected to the primary circuit and the secondary circuit in sequence. The primary circuit is connected to the first input terminal, and the secondary circuit is connected to the second input terminal.

[0016] Furthermore, the main control unit also includes capacitors C5 and C6 connected in parallel. The main control chip has a first pin. One end of capacitor C6 is grounded, and the other end of capacitor C6 is connected to the first pin of the main control chip. The other end of capacitor C6 is connected to the fourth pin of the main control chip through resistor R6, and the other end of capacitor C6 is connected to the second input terminal. The second input terminal is used to supply power to the main control chip.

[0017] Furthermore, the switching unit includes a transistor Y1 and a relay, the relay including a relay switch and a relay body, and the main control chip has a sixth pin. One end of the relay body is connected to the first input terminal, and the other end of the relay body is connected to the collector of transistor Q1. The emitter of transistor Q1 is grounded, and the base of transistor Q1 is connected to the sixth pin through resistor R5. The relay switch is located on the live wire. The first input terminal supplies power to the relay body. When the relay body is energized, it becomes magnetic, attracting the relay switch and causing it to close.

[0018] Furthermore, the standby current detection unit includes a voltage clamping circuit and a current transformer circuit. The main control chip has a seventh pin, which is connected to the seventh pin of the main control chip, and the current transformer circuit is connected to the voltage clamping circuit. The current transformer circuit generates an AC voltage based on the mains power supply.

[0019] Furthermore, the voltage clamping circuit includes a resistor R7 and a diode D4, and the current transformer circuit includes a current transformer L2 and a resistor R9. The seventh pin is connected to the cathode of diode D4, and the anode of diode D4 is grounded. The seventh pin is connected to one end of resistor R9 through resistor R7, and the other end of resistor R9 is grounded. The current transformer L2 is connected in parallel with resistor R9. Resistor R7 and diode D4 form a 2V voltage clamping circuit to ensure that the voltage at the seventh pin of the main control chip does not exceed 2V, thereby ensuring the main control chip is in a safe state.

[0020] Furthermore, the leakage current detection unit includes a current transformer L1 and a resistor R8. The resistor R8 and the current transformer L2 are connected in parallel. The main control chip has a third pin. One end of the resistor R8 is grounded, and the other end of the resistor R8 is connected to the third pin of the main control chip.

[0021] Furthermore, the application circuit of the air conditioner intelligent overload protection standby socket also includes a power indicator light S1 and a resistor R3. The positive terminal of the power indicator light S1 is connected to the second input terminal through the resistor R3, and the negative terminal of the power indicator light S1 is grounded. The power indicator light S1 is used to indicate whether the second input terminal is supplying power to the main control chip. When the power indicator light S1 is lit, the second input terminal supplies power to the main control chip.

[0022] Furthermore, the infrared remote control unit includes an infrared receiver. The main control chip has a fifth pin. The first terminal of the infrared receiver is connected to the second input terminal, the second terminal is connected to the fifth pin, and the third terminal is grounded. It should be noted that the infrared receiver can only be used after it has been properly paired with the air conditioner remote control. To prevent malfunctions, the infrared receiver can only control the internal circuitry of the socket to conduct through the main control chip, causing the socket to output 220V voltage; it cannot control the internal circuitry of the socket to disconnect through the main control chip, causing the socket to stop outputting 220V voltage.

[0023] In one working scenario, when the intelligent overload protection standby socket for an air conditioner is powered on, the main control chip is in operation. Pin 6 is outputting a low level by default, transistor Y1 is cut off, the relay switch is open, and the socket has no 220V voltage output. Pressing the button causes the indicator light S2 to stay on, pin 6 to continuously output a high level, transistor Y1 to conduct, the relay switch to close, and the socket to output 220V voltage.

[0024] When the leakage current detected by the third pin exceeds the set value (preferably 15mA), the sixth pin stops outputting a continuous high level, transistor Y1 is cut off, the relay switch is turned off, and the socket has no 220V voltage output. At the same time, the working indicator light S2 flashes slowly at a frequency of 3 times per second as an alarm. After the fault is cleared, the button needs to be pressed again to resume operation; the button is ineffective during a fault.

[0025] When the overload current detected by the seventh pin exceeds the preset value (preferably 10A), the sixth pin stops outputting a continuous high level, transistor Q1 is cut off, the relay switch is opened, and the socket has no 220V voltage output. At the same time, the working indicator LED2 flashes rapidly at a frequency of 5 times per second to indicate an alarm. After the fault is cleared, the button needs to be pressed again to resume operation; the button is ineffective during a fault.

[0026] When the air conditioner is working, current flows through the current transformer L2, forming an AC voltage across resistor R9. This AC voltage is then current-limited by resistor R7 and regulated by diode D4 before being applied to pin 7 of the main control chip. When this AC voltage reaches a set value (preferably 0.5V-2V), the main control chip issues a command to continuously output a high level on pin 6.

[0027] When the air conditioner is turned off, the current on the current transformer L2 is less than 45mA and the voltage on the resistor R9 is less than 0.5V. At this time, the sixth pin of the main control chip stops outputting a high level, the transistor Y1 is cut off, and the relay G1 is disconnected, thereby completely cutting off the power supply and achieving the purpose of standby power-off.

[0028] Compared with the prior art, the beneficial effects of this application are as follows: First, it significantly saves energy and reduces consumption, resulting in outstanding economic benefits: Through the cooperation of the standby current detection unit and the main control unit, it can accurately identify in real time when the air conditioner enters standby mode (power consumption reduced to an extremely low level) and automatically control the switching unit to cut off the power supply, completely eliminating standby power consumption. For the huge number of air conditioning devices in the country, this can effectively avoid the aforementioned waste of up to tens of billions of kilowatt-hours of standby power annually, saving users considerable electricity expenses, while also playing a positive role in promoting national energy conservation, emission reduction, and the achievement of "dual carbon" goals.

[0029] Secondly, it enhances electrical safety and provides proactive protection: This application integrates a leakage current detection unit, which can continuously monitor leakage anomalies in the power supply circuit. Once a leakage current that may endanger personal safety is detected, the main control unit will immediately drive the switch unit to disconnect the live wire, quickly cut off the power supply, effectively prevent electric shock accidents, make up for the lack of safety protection functions in traditional air conditioner sockets, and add a reliable technical guarantee for electrical safety in homes and public places.

[0030] Third, intelligent automatic control, requiring no user intervention: The entire standby power-off and leakage protection process is intelligently judged and executed automatically by the circuit, without the need for manual plugging / unplugging or additional attention from the user. This not only greatly improves the convenience of use, but also avoids the continuous generation of standby power consumption or the long-term existence of safety hazards due to human forgetfulness, realizing "maintenance-free" intelligent energy management and safety protection.

[0031] Fourth, it boasts high functional integration and a compact, practical structure: integrating standby detection, leakage protection, intelligent control, and power management modules into a single application circuit, achieving dual core values ​​(energy saving and safety). Compared to solutions requiring multiple external independent devices (such as timers and independent leakage protectors), this application design is simpler, lower in cost, easier to install and use, and easier to promote and popularize.

The second input terminal 62 is used to supply power to the main control chip M3.

[0047] Furthermore, the switching unit 30 includes a transistor Y1 and a relay, the relay including a relay switch G2 and a relay body G1, and the main control chip M3 has a sixth pin. One end of the relay body G1 is connected to the first input terminal 61, and the other end of the relay body G1 is connected to the collector of transistor Q1. The emitter of transistor Q1 is grounded, and the base of transistor Q1 is connected to the sixth pin through resistor R5. Relay switch G2 is located on the live wire L. The first input terminal 61 supplies power to the relay body G1. When the relay body G1 is energized, it becomes magnetic, attracting the relay switch G2 and causing G2 to close.

[0048] Furthermore, the standby current detection unit 40 includes a voltage clamping circuit 41 and a current transformer circuit 42. The main control chip M3 has a seventh pin. The voltage clamping circuit 41 is connected to the seventh pin of the main control chip M3, and the current transformer circuit 42 is connected to the voltage clamping circuit 41.

[0056] When the air conditioner is working, current flows through the current transformer L2, forming an AC voltage across resistor R9. This AC voltage is then limited by resistor R7 and regulated by diode D4 before being applied to pin 7 of the main control chip M3. When this AC voltage reaches a set value (preferably 0.5V-2V), the main control chip M3 issues a command to continuously output a high level from pin 6.

[0057] When the air conditioner is turned off, the current on the current transformer L2 is less than 45mA and the voltage on the resistor R9 is less than 0.5V.
