Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioner and a control method thereof, an indoor unit, and a storage medium. Background Art

[0002] The indoor unit and outdoor unit of the split air conditioner usually communicate through the current loop communication circuit. The indoor unit uses a high-power relay to control the power supply of the outdoor unit. In the process of the indoor unit controlling the outdoor unit to wake up through the high-power relay, the current loop communication loop between the indoor unit and the outdoor unit is disconnected. When the indoor unit detects a signal on the current loop communication loop, the indoor unit determines that the outdoor unit has completed the wake-up and then starts to execute the control command. However, the current loop communication loop may be affected by electromagnetic interference, resulting in interference signals in the loop, causing the indoor unit to mistakenly determine that the outdoor unit has completed the wake-up. At this time, the outdoor unit cannot respond to the control command of the indoor unit, which affects the operation of the air conditioner. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art to at least a certain extent. To this end, the first object of the present invention is to provide a control method for an air conditioner, which determines that the outdoor unit has completed waking up when a feedback signal satisfies a preset waking up condition determined based on a first preset control signal and a second preset control signal, thereby accurately judging whether the outdoor unit has completed waking up, thereby improving the reliability of the air conditioner.

[0004] A second object of the present invention is to provide a computer-readable storage medium.

[0005] The third object of the present invention is to provide an indoor unit.

[0006] A fourth object of the present invention is to provide an air conditioner.

[0007] To achieve the above-mentioned purpose, a control method of an air conditioner is proposed according to a first aspect of an embodiment of the present invention. The air conditioner includes an outdoor unit and an indoor unit. The outdoor unit includes a first receiving unit, a first controllable switch unit, a second controllable switch unit, a first sending unit and a first charging unit. The indoor unit includes a second sending unit and a second receiving unit. The second controllable switch unit is configured to send a first feedback signal to the second receiving unit when the first receiving unit receives a signal sent by the second sending unit, so that the first controllable switch unit is turned on, so that the first charging unit wakes up the outdoor unit according to the power provided by the first controllable switch unit, and stops sending the first feedback signal when the outdoor unit completes the wake-up. To disconnect the first controllable switch unit, the first sending unit is configured to send a second feedback signal to the second receiving unit according to the first preset control signal after the first controllable switch unit is disconnected, so as to establish communication with the indoor unit. The method includes: when the indoor unit is powered on and receives a control instruction, controlling the second sending unit to send a wake-up signal to the first receiving unit according to the second preset control signal to turn on the first controllable switch unit; when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, determining that the outdoor unit has completed the wake-up, and controlling the indoor unit according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal.

[0008] According to the control method of the air conditioner of an embodiment of the present invention, when the indoor unit is powered on and receives a control instruction, the second sending unit is controlled according to the second preset control signal to send a wake-up signal to the first receiving unit to turn on the first controllable switch unit, and when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, it is determined that the outdoor unit has completed the wake-up, and the indoor unit is controlled according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, the outdoor unit includes a first receiving unit, a first controllable switch unit, a second controllable switch unit, a first sending unit and a first charging unit, the indoor unit includes a second sending unit and a second receiving unit, and the first sending unit is configured to send a second feedback signal to the second receiving unit according to the first preset control signal after the first controllable switch unit is disconnected, so as to establish communication with the indoor unit. Therefore, because the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, and the first sending unit sends the second feedback signal to the second receiving unit based on the first preset control signal after the outdoor unit completes the wake-up, the feedback signal output by the second receiving unit can meet the preset wake-up condition only after receiving the correct second feedback signal. Therefore, when the feedback signal meets the preset wake-up condition, it can be determined that the outdoor unit has completed the wake-up, thereby achieving accurate judgment on whether the outdoor unit has completed the wake-up, thereby improving the reliability of the air conditioner.

[0009] According to one embodiment of the present invention, when the duty cycle of the first preset control signal is less than 1, the method further includes: when the feedback signal is a superposition signal of the first preset control signal and the second preset control signal, determining that the feedback signal satisfies a preset wake-up condition.

[0010] According to one embodiment of the present invention, when the duty cycle of the first preset control signal is 1, the method further includes: when the feedback signal is interrupted and the feedback signal is a second preset control signal after a first preset time length, determining that the feedback signal satisfies a preset wake-up condition.

[0011] According to an embodiment of the present invention, the duty cycle of the second preset control signal remains unchanged.

[0012] According to an embodiment of the present invention, the duty cycle of the second preset control signal is between 0.5-1.

[0013] According to an embodiment of the present invention, the duty cycle of the second preset control signal is adjusted based on the wake-up duration of the outdoor unit.

[0014] According to an embodiment of the present invention, the first preset control signal and the second preset control signal are data packets respectively.

[0015] According to one embodiment of the present invention, after controlling the indoor unit according to the control instruction, the method also includes: when receiving a shutdown instruction, controlling the second sending unit to send a shutdown signal to the first receiving unit so that the outdoor unit enters a standby state according to the shutdown signal; controlling the first sending unit to stop sending the shutdown signal.

[0016] To achieve the above-mentioned purpose, according to a second aspect of the present invention, a computer-readable storage medium is provided, on which a control program for an air conditioner is stored. When the control program for the air conditioner is executed by a processor, the control method for the air conditioner of any of the aforementioned embodiments is implemented.

[0017] According to the computer-readable storage medium of an embodiment of the present invention, by executing a computer program of the above-mentioned air conditioner control method, when the feedback signal meets the preset wake-up condition determined based on the first preset control signal and the second preset control signal, it is determined that the outdoor unit has completed the wake-up, thereby achieving accurate judgment on whether the outdoor unit has completed the wake-up, thereby improving the reliability of the air conditioner.

[0018] To achieve the above-mentioned purpose, according to an embodiment of the third aspect of the present invention, an indoor unit is proposed, comprising a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor. When the processor executes the air conditioner control program, the air conditioner control method of any of the aforementioned embodiments is implemented.

[0019] According to the indoor unit of the embodiment of the present invention, the computer program of the control method of the above-mentioned air conditioner is executed by the processor.

[0020] To achieve the above-mentioned purpose, an air conditioner is proposed according to a fourth aspect of the present invention, comprising: an outdoor unit and an indoor unit, wherein the outdoor unit comprises a first receiving unit, a first controllable switch unit, a second controllable switch unit, a first sending unit, a first charging unit and an outdoor unit control unit, and the indoor unit comprises a second sending unit, a second receiving unit and an indoor unit control unit, the second controllable switch unit being configured to send a first feedback signal to the second receiving unit when the first receiving unit receives a signal sent by the second sending unit, so as to turn on the first controllable switch unit, and to stop sending the first feedback signal when the outdoor unit completes the wake-up, so as to turn off the first controllable switch unit, and the first charging unit being configured to receive a signal from the first controllable switch unit according to the power provided by the first controllable switch unit. The source supplies power to the outdoor unit control unit to wake up the outdoor unit, the first sending unit is configured to send a second feedback signal to the second receiving unit according to the first preset control signal after the first controllable switch unit is disconnected, so as to establish communication with the indoor unit, the indoor unit control unit is configured to control the second sending unit to send a wake-up signal to the first receiving unit according to the second preset control signal when the indoor unit is powered on and receives a control instruction, so as to turn on the first controllable switch unit, and determine that the outdoor unit has completed the wake-up when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, and control the indoor unit according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal.

Therefore, because the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, and the first sending unit sends the second feedback signal to the second receiving unit based on the first preset control signal after the outdoor unit completes the wake-up, the feedback signal output by the second receiving unit can meet the preset wake-up condition only after receiving the correct second feedback signal.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The air conditioner and its control method, indoor unit, and storage medium according to the embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Figure 1 FIG. 1 is a schematic diagram of the structure of an air conditioner according to an embodiment of the present invention. Figure 1 As shown, the air conditioner includes an outdoor unit 100 and an indoor unit 200, the outdoor unit 100 includes a first receiving unit 110, a first controllable switch unit 120, a second controllable switch unit 130, a first sending unit 140, a first charging unit 150 and an outdoor unit control unit 160, and the indoor unit 200 includes a second sending unit 210, a second receiving unit 220 and an indoor unit control unit 230.

[0035] The indoor unit 200 is connected to the outdoor unit 100 via a communication line S, a neutral line N, a live line L and a common ground line PE. The input end of the first receiving unit 110 is connected to the second sending unit 210 through the neutral line N, the first control end of the first controllable switch unit 120 is connected to the output end of the first receiving unit 110, the input end of the second controllable switch unit 130 is connected to the second control end of the first controllable switch unit 120, the output end of the first controllable switch unit 120 is connected to the live line L, the input end of the first controllable switch unit 120 is connected to the first input end of the first charging unit 150, the first output end of the second controllable switch unit 130 is connected to the second receiving unit 220 through the communication line S, the input end of the first sending unit 140 is connected to the output end of the first receiving unit 110, the control end of the first sending unit 140 is connected to the first output end of the outdoor unit control unit 160, the output end of the first sending unit 140 is connected to the second receiving unit 220 through the communication line S, and the output end of the first charging unit 150 is connected to the power supply end of the power supply unit of the outdoor unit 100, so as to supply power to the outdoor unit control unit 160 according to the power provided by the first controllable switch unit 120, so as to wake up the outdoor unit 100. The second controllable switch unit 130 is configured to send a first feedback signal to the second receiving unit 220 when the first receiving unit 110 receives a signal sent by the second sending unit 210, so that the first controllable switch unit 120 is turned on, so that the first charging unit 150 wakes up the outdoor unit 100 according to the power provided by the first controllable switch unit 120, and stops sending the first feedback signal when the outdoor unit 100 completes the wake-up, so that the first controllable switch unit 120 is turned off. The outdoor unit control unit 160 is configured to control the first sending unit 140 to send a second feedback signal to the second receiving unit 220 according to the first preset control signal after the first controllable switch unit 120 is turned off, so as to establish communication with the indoor unit 200. The control end of the second sending unit 210 is connected to the output end of the outdoor unit control unit 160, the input end of the second sending unit 210 is connected to the first output end of the second receiving unit 220, and the second output end of the second receiving unit 220 is connected to the input end of the outdoor unit control unit 160.

[0036] The control method of the air conditioner of this embodiment can be applied to the indoor unit control unit 230. When the indoor unit control unit 230 controls the second sending unit 210 to send a signal to the first receiving unit 110, the second sending unit 210, the first receiving unit 110, the first controllable switch unit 120, the second controllable switch unit 130 and the second receiving unit 220 form a communication loop, the first controllable switch unit 120 is turned on, the first controllable switch unit 120 provides power to the first charging unit 150, and the first charging unit 150 supplies power to the outdoor unit control unit 160 according to the power to wake up the outdoor unit 100. After the outdoor unit 100 completes the wake-up, the outdoor unit control unit 160 controls the second controllable switch unit 130 to stop sending the first feedback signal to the second receiving unit 220, so that the communication loop formed by the second sending unit 210, the first receiving unit 110, the first controllable switch unit 120, the second controllable switch unit 130 and the second receiving unit 220 is disconnected, so the first controllable switch unit 120 is disconnected. After the first controllable switch unit 120 is disconnected, the outdoor unit control unit 160 controls the first sending unit 140 to send a second feedback signal to the second receiving unit 220 according to the first preset control signal, and the second sending unit 210, the first receiving unit 110, the first sending unit 140 and the second receiving unit 220 form a communication loop, and the outdoor unit 100 establishes communication with the indoor unit 200.

[0037] Therefore, the indoor unit 200 of this embodiment only has a communication circuit, and no switch circuit is set to control the awakening of the outdoor unit 100. Therefore, the pre-charge current and operating current of the outdoor unit 100 will not flow through the indoor unit 200, nor will they pass through the communication line S, thereby improving the safety of the air conditioner; and, because the communication line S will not be used as a power line, the mains high voltage will not be introduced into the communication loop.

[0038] Figure 2 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the control method of the air conditioner includes:

[0039] S301, when the indoor unit is powered on and receives a control instruction, controlling the second sending unit to send a wake-up signal to the first receiving unit according to a second preset control signal, so as to turn on the first controllable switch unit.

[0040] Specifically, Figure 1As shown, the indoor unit 200 further includes a second charging unit 240, and the input end of the second charging unit 240 is connected to the live wire L to supply power to the indoor unit control unit 230, so that the indoor unit 200 is powered on. When the target control is triggered, a control instruction is generated. For example, assuming that the target control is a remote control, the user can select a cooling function or a heating function on the remote control to send a control instruction to the indoor unit 200. The indoor unit control unit 230 controls the second sending unit 210 to send a wake-up signal to the first receiving unit 110 according to the second preset control signal, so that the first controllable switch unit 120 is turned on, thereby waking up the outdoor unit 100.

[0041] In an optional embodiment, if Figure 1 As shown, the second sending unit 210 includes a first transistor Q1, a second photocoupler IC2, a first resistor R1, a second resistor R2 and a communication power supply 211. The control end of the first transistor Q1 is connected to the first output end of the indoor unit control unit 230 through the third resistor R3. The emitter of the first transistor Q1 is grounded, the collector of the first transistor Q1 is connected to one end of the first resistor R1, the other end of the first resistor R1 is connected to one end of the second resistor R2, the other end of the second resistor R2 is suitable for inputting a preset power supply, the anode of the light-emitting part of the second photocoupler IC2 is connected to the other end of the first resistor R1, the cathode of the light-emitting part of the second photocoupler IC2 is connected to one end of the first resistor R1, and the light-receiving part of the second photocoupler IC2 is connected to the communication power supply 211. The communication power supply 211 includes a fourth resistor R4, a first voltage-stabilizing diode ZV1, a first capacitor C1 and a fifth resistor R5. One end of the fourth resistor R4 is connected to one end of the light-receiving part of the second photocoupler IC2, and the other end of the fourth resistor R4 is connected to the neutral line N. The first voltage-stabilizing diode ZV1 and the first capacitor C1 are connected in parallel and then connected in parallel with the fourth resistor R4. One end of the fifth resistor R5 is connected to one end of the fourth resistor R4, and the other end of the fifth resistor R5 is connected to the live line L through the first diode D1.

[0042] Specifically, Figure 3 As shown, at time t0, the indoor unit is powered on and the communication power supply is established at the same time. At time t1, the indoor unit control unit receives the control instruction and controls the first transistor according to the second preset control signal. When the second preset control signal is at a high level, the first transistor is turned on, the second sending unit sends a signal to the first receiving unit, and the first controllable switch unit is turned on; when the second preset control signal is at a low level, the first transistor is turned off, the second sending unit stops sending signals, and the first controllable switch unit is turned off.

[0043] Further, such as Figure 1 As shown, the indoor unit 200 further includes a display unit 250. When the indoor unit 200 is powered on, the display unit 250 is also powered on and operates.

[0044] It should be noted that the communication power supply 211 can be obtained by half-wave rectification of the live line L and the neutral line N, or can be obtained through a switching power supply (not shown) in the indoor unit 200, or can be directly powered by an external DC power supply.

[0045] In an optional embodiment, if Figure 1 As shown, the second charging unit 240 includes a second rectifier module 251 and a second electrolytic capacitor E2, the second rectifier module 251 includes four diodes, the anode of the second diode D2 is connected to the neutral line N, the cathode of the second diode D2 is connected to the cathode of the third diode D3, the anode of the third diode D3 is connected to the live line L through the first fuse, the cathode of the fourth diode D4 is connected to the anode of the second diode D2, the cathode of the fifth diode D5 is connected to the anode of the third diode D3, the anode of the fifth diode D5 is connected to the anode of the fourth diode D4, one end of the second electrolytic capacitor E2 is respectively connected to the cathode of the third diode D3 and the first power supply end of the indoor unit 200 power supply unit, and the other end of the second electrolytic capacitor E2 is respectively connected to the cathode of the fifth diode D5 and the second power supply end of the indoor unit 200 power supply unit. The second rectifier module 251 rectifies the city power, then charges the second electrolytic capacitor E2, and supplies power to the indoor unit control unit 230 to power on the indoor unit 200.

[0046] S302, when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, it is determined that the outdoor unit has completed the wake-up, and the indoor unit is controlled according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal.

[0047] Specifically, after the first controllable switch unit is turned on, the first charging unit wakes up the outdoor unit according to the AC power. At this time, the first feedback signal output by the second controllable switch unit, the feedback signal output by the second receiving unit, and the feedback signal output by the second sending unit are synchronized. When the outdoor unit completes the wake-up, the outdoor unit control unit controls the second controllable switch end element to stop sending the first feedback signal so that the first controllable switch unit is disconnected, and after the first controllable switch unit is disconnected, controls the first sending unit to send the second feedback signal to the second receiving unit according to the first preset control signal. The preset wake-up condition is determined based on the first preset control signal and the second preset control signal. Therefore, only after the second receiving unit receives the second feedback signal, the feedback signal output by the second receiving unit can meet the preset wake-up condition. Because the first sending unit sends the second feedback signal after the outdoor unit completes the wake-up, it can be determined that the outdoor unit has completed the wake-up when the feedback signal meets the preset wake-up condition. Figure 3As shown, the indoor unit control unit determines whether the outdoor unit has completed the awakening from time t3 to t4, and controls the indoor unit according to the control instruction (from time t4 to time t5) when it is determined that the outdoor unit has completed the awakening. At this time, the indoor unit and the outdoor unit exchange information through the communication loop composed of the second sending unit, the first receiving unit, the first sending unit and the second receiving unit, so that the indoor unit and the outdoor unit respectively operate according to the control instruction.

[0048] In an optional embodiment, if Figure 1 As shown, the first charging unit 150 includes: a rectifier diode D and a first electrolytic capacitor E1, wherein the cathode of the rectifier diode D is connected to the output end of the first controllable switch unit 120; one end of the first electrolytic capacitor E1 is connected to the anode of the rectifier diode D, and the other end of the first electrolytic capacitor E1 is connected to the outdoor unit control unit 160.

[0049] Specifically, during the process of waking up the outdoor unit 100, the live wire L can charge the first electrolytic capacitor E1 through the first controllable switch unit 120, the first thermistor PTC1 and the rectifier diode D. The charging current direction is as follows: Figure 4 As shown. Figure 3 As shown, at time t1, the first controllable switch unit 120 is turned on to provide the mains power to the rectifier diode D. In the negative half cycle of the mains power, the rectifier diode D is turned on to generate Figure 3 Therefore, the rectifier diode D can be selected from diodes with larger rated current, so that the first electrolytic capacitor E1 can be charged with a larger charging current.

[0050] In some embodiments, Figure 1 As shown, the first controllable switch unit 120 includes a first photocoupler IC1, the anode of the light-emitting part of the first photocoupler IC1 is connected to the output end of the first receiving unit 110, the cathode of the light-emitting part of the first photocoupler IC1 is connected to the input end of the second controllable switch unit 130, one end of the light-receiving part of the first photocoupler IC1 is connected to the cathode of the rectifier diode D, and the other end of the light-receiving part of the first photocoupler IC1 is connected to the live wire L.

[0051] That is to say, the current generated by the communication power supply 211 flows through the first receiving unit 110 and then flows into the light receiving part of the first photocoupler IC1, and the first photocoupler IC1 is turned on. Because the first charging unit 150 adopts a half-wave rectification method, the first photocoupler IC1 can use a single-phase conduction device, which can effectively reduce the circuit cost compared to the full-bridge rectification that requires the use of a bidirectional conduction device.

[0052] Furthermore, the first controllable switch unit 120 further includes a sixth resistor R6 , one end of which is connected to the cathode of the light-emitting portion of the first photocoupler IC1 , and the other end of which is connected to the input end of the second controllable switch unit 130 .

[0053] In some embodiments, the first photocoupler IC1 is a Darlington photocoupler.

[0054] It is understandable that because the Darlington photocoupler uses two transistors inside, the Darlington photocoupler has a strong voltage resistance and can withstand higher voltages.

[0055] In an optional embodiment, if Figure 1 As shown, the outdoor unit 100 further includes a voltage detection unit 170 and a third controllable switch unit 180. The voltage detection unit 170 detects the voltage across the first electrolytic capacitor E1 to generate a voltage detection value, and sends the voltage detection value to the outdoor unit control unit 160. One end of the third controllable switch unit 180 is connected to the live wire L through the second fuse FUSE2, and the other end of the third controllable switch unit 180 is connected to the first charging unit 150. The outdoor unit control unit 160 is also configured to determine that the outdoor unit 100 has completed the wake-up when the voltage detection value is greater than a preset voltage threshold, and control the second controllable switch unit 130 to stop sending the first feedback signal, and control the third controllable switch unit 180 to provide power to the first charging unit 150.

[0056] The first receiving unit 110 includes a seventh resistor R7, a third photocoupler IC3, an eighth resistor R8 and a ninth resistor R9, one end of the seventh resistor R7 is connected to the neutral line N, the other end of the seventh resistor R7 is connected to the first control end of the first controllable switch unit 120, the anode of the light-emitting part of the third photocoupler IC3 is connected to one end of the seventh resistor R7, the cathode of the light-emitting part of the third photocoupler IC3 is connected to the other end of the seventh resistor R7, one end of the light-receiving part of the third photocoupler IC3 is suitable for inputting a preset power supply, the other end of the light-receiving part of the third photocoupler IC3 is connected to one end of the eighth resistor R8, the other end of the eighth resistor R8 is grounded, one end of the ninth resistor R9 is connected to one end of the eighth resistor R8, and the other end of the ninth resistor R9 is connected to the first input end of the outdoor unit control unit 160.

[0057] The second controllable switch unit 130 includes a first relay K1 and a first driving module 131, the first end 1 of the first relay K1 is connected to the other end of the sixth resistor R6, the second end 2 of the first relay K1 is suspended, the third end 3 of the first relay K1 is connected to the communication line S through the tenth resistor R10 and the sixth diode D6, the input end of the first driving module 131 is connected to the first output end of the outdoor unit control unit 160, the output end of the first driving module 131 is connected to one end of the coil of the first relay K1, the other end of the coil of the first relay K1 is suitable for inputting a preset power supply, and the first end 1 and the third end 3 of the first relay K1 are normally closed contacts.

[0058] The third controllable switch unit 180 includes a second relay K2 and a second drive module 181, one end of the second relay K2 is connected to the live wire L through the second fuse FUSE2, the other end of the second relay K2 is connected to the first charging unit 150, the input end of the second drive module 181 is connected to the second output end of the outdoor unit control unit 160, the output end of the second drive module 181 is connected to one end of the coil of the second relay K2, and the other end of the coil of the second relay K2 is suitable for inputting a preset power supply.

[0059] Specifically, the current output by the communication power supply 211 flows through the neutral line N, the light-emitting part of the third photocoupler IC3, the light-emitting part of the first photocoupler IC1, the first end 1 of the first relay K1, the third end 3 of the first relay K1, the tenth resistor R10, the sixth diode D6, the second receiving unit 220, and then flows into the first capacitor C1. At this time, the first photocoupler IC1 is turned on, the first charging unit 150 rectifies the city power, and supplies power to the outdoor unit control unit 160. When the voltage detection value is greater than the preset voltage threshold, the outdoor unit control unit 160 sends a first drive signal to the first drive module 131, so that the first drive module 131 drives the first end and the second end of the first relay K1 to be attracted according to the first drive signal, and sends a second drive signal to the second drive module 181, so that the second drive module 181 drives the second relay K2 to be attracted according to the second drive signal. At this time, the first photocoupler IC1 is disconnected from the communication loop and stops providing power to the first charging unit 150. At the same time, the third controllable switch unit 180 provides power to the first charging unit 150.

[0060] In some embodiments, Figure 1As shown, the first charging unit 150 also includes a first rectifier module 151, which includes 4 diodes, the anode of the seventh diode D7 is connected to the zero line N, the cathode of the seventh diode D7 is respectively connected to the cathode of the eighth diode D8 and the other end of the first electrolytic capacitor E1, the anode of the eighth diode D8 is connected to the other end of the second relay K2, the cathode of the ninth diode D9 is connected to the anode of the seventh diode D7, the cathode of the tenth diode D10 is connected to the anode of the eighth diode D8, and the anode of the tenth diode D10 is respectively connected to the anode of the ninth diode D9 and one end of the first electrolytic capacitor E1. The first rectifier module 151 performs full-wave rectification on the power provided by the third controllable switch unit 180 to charge the first electrolytic capacitor E1.

[0061] In some embodiments, when the duty cycle of the first preset control signal is less than 1, the method further includes: when the feedback signal is a superposition signal of the first preset control signal and the second preset control signal, determining that the feedback signal satisfies a preset wake-up condition.

[0062] Specifically, when the first preset control signal is at a high level and the second preset control signal is at a high level, the first sending unit is turned on, the first sending unit sends a signal to the second receiving unit, the second receiving unit is turned on, and the feedback signal is at a high level; when at least one of the first preset control signal and the second preset control signal is at a low level, the first sending unit is turned off, the first sending unit stops sending a signal to the second receiving unit, the second receiving unit is turned off, and the feedback signal is at a low level. When the duty cycle of the first preset control signal is less than 1, the first sending unit and the second sending unit are not turned on at the same time, so the feedback signal during the outdoor unit wake-up process and the feedback signal after the outdoor unit completes the wake-up are different. The feedback signal after the outdoor unit completes the wake-up is a superposition signal of the first preset control signal and the second preset control signal. Therefore, when the feedback signal is a superposition signal of the first preset control signal and the second preset control signal, it can be determined that the outdoor unit has completed the wake-up.

[0063] It should be noted that the duty cycle of the first preset control signal may also be variable.

[0064] In an optional embodiment, if Figure 1As shown, the first sending unit 140 includes a second transistor Q2, an eleventh resistor R11, a twelfth resistor R12 and a fourth photocoupler IC4, wherein the control end of the second transistor Q2 is connected to the outdoor unit control unit 160 through the thirteenth resistor R13, the emitter of the second transistor Q2 is grounded, one end of the eleventh resistor R11 is connected to the collector of the second transistor Q2, one end of the twelfth resistor R12 is suitable for connecting to a preset power supply, the other end of the twelfth resistor R12 is connected to the other end of the eleventh resistor R11, the anode of the light-emitting part of the fourth photocoupler IC4 is connected to the other end of the eleventh resistor R11, the cathode of the light-emitting part of the fourth photocoupler IC4 is connected to one end of the eleventh resistor R11, one end of the light-receiving part of the fourth photocoupler IC4 is connected to the output end of the first receiving unit 110, and the other end of the light-receiving part of the fourth photocoupler IC4 is connected to the tenth resistor R10.

[0065] The second receiving unit 220 includes an eleventh diode D2, a second thermistor PTC2, a fourteenth resistor R14, a fifth photocoupler IC5, a fifteenth resistor R15 and a sixteenth resistor R16, wherein the anode of the eleventh diode D2 is connected to the communication line S, the cathode of the eleventh diode D2 is connected to one end of the second thermistor PTC2, the other end of the second thermistor PTC2 is respectively connected to one end of the fourteenth resistor R14 and the anode of the light-emitting portion of the fifth photocoupler IC5, the other end of the fourteenth resistor R14 is respectively connected to the cathode of the light-emitting portion of the fifth photocoupler IC5 and the other end of the light-receiving portion of the second photocoupler IC2, one end of the light-receiving portion of the fifth photocoupler IC5 is suitable for inputting a preset power supply, the other end of the light-receiving portion of the fifth photocoupler IC5 is connected to the input end of the indoor unit control unit 230 through the fifteenth resistor R15, one end of the sixteenth resistor R16 is connected to the other end of the light-receiving portion of the fifth photocoupler IC5, and the other end of the sixteenth resistor R16 is grounded.

[0066] Specifically, Figure 3 As shown, when the second preset control signal is at a high level, the first transistor is turned on, and the second sending unit 210 is turned on. At this time, if the first preset control signal is at a high level, the second transistor Q2 is also turned on, the first sending unit 140 is turned on, and the first sending unit 140 sends the second feedback signal to the second receiving unit 220, so the fifth photocoupler IC5 is turned on, and the feedback signal is at a high level; if the first preset control signal is at a low level, the first sending unit 140 is turned off, the fifth photocoupler IC5 is turned off, and the feedback signal is at a low level. When the second preset control signal is at a low level, the first transistor is turned off, and the second sending unit 210 is turned off. Therefore, both the first sending unit 140 and the second receiving unit 220 are turned off, so the feedback signal is at a low level.

[0067] In some embodiments, when the duty cycle of the first preset control signal is 1, the method further includes: when the feedback signal is interrupted and the feedback signal is a second preset control signal after the first preset time length, determining that the feedback signal satisfies the preset wake-up condition.

[0068] Specifically, during the outdoor unit wake-up process, because the first controllable switch unit is switched based on the second preset control signal, the feedback signal is the second preset control signal. When the duty cycle of the first preset control signal is 1, the second transistor is in a normally on state, and the feedback signal of the second receiving unit is the second preset control signal. Therefore, the feedback signal during the outdoor unit wake-up process is the same as the feedback signal after the outdoor unit completes the wake-up. Therefore, when the feedback signal is the second preset control signal, it is impossible to determine whether the outdoor unit has completed the wake-up. Figure 3 As shown, at time t2, when the voltage detection value is greater than the preset voltage threshold, the outdoor unit control unit controls the second controllable switch unit to stop sending the first feedback signal, and after the first preset time (i.e., from time t2 to time t3), controls the first sending unit to send the second feedback signal according to the second preset control signal. Therefore, when the feedback signal interrupts the first preset time, and the second preset control signal is sent after the first preset time, it can be determined that the outdoor unit has completed the wake-up.

[0069] In the above embodiment, during the outdoor unit wake-up process, the feedback signal is the same as the second preset control signal. After the outdoor unit completes the wake-up, the feedback signal is a superposition signal of the first preset control signal and the second preset control signal. Therefore, when the feedback signal satisfies the preset wake-up condition determined based on the first preset control signal and the second preset control signal, it can be determined that the outdoor unit has completed the wake-up, thereby achieving accurate judgment of whether the outdoor unit has completed the wake-up, thereby improving the reliability of the air conditioner.

[0070] In some embodiments, the duty cycle of the second preset control signal remains unchanged.

[0071] It can be understood that the first controllable switch unit is switched based on the second preset control signal, and when the duty cycle of the second preset control signal remains unchanged, the first controllable switch unit provides power to the first charging unit according to the fixed duty cycle.

[0072] Furthermore, in some embodiments, the duty cycle of the second preset control signal is between 0.5-1.

[0073] That is to say, during the wake-up process of the outdoor unit, the first controllable switch unit is not necessarily in a normally open state. Therefore, the charging current of the first electrolytic capacitor can be limited by adjusting the duty cycle of the second preset control signal, thereby controlling the charging speed and reducing the consumption of electric energy. It should be noted that the larger the duty cycle of the second preset control signal, the larger the charging current of the first electrolytic capacitor and the faster the charging speed.

[0074] In some embodiments, the duty cycle of the second preset control signal is adjusted based on the wake-up duration of the outdoor unit.

[0075] Specifically, the duty cycle of the second preset control signal can be adjusted according to the wake-up time of the outdoor unit. For example, when the outdoor unit is just powered on, in order to reduce the current shock, the duty cycle of the second preset control signal can be relatively small, and then gradually increase the duty cycle of the second preset control signal to achieve fast charging.

[0076] In the above embodiment, the duty cycle of the second preset control signal is dynamically adjusted according to the wake-up time of the outdoor unit, so as to optimize the use efficiency of the power supply and reduce unnecessary loss.

[0077] In some embodiments, the first preset control signal and the second preset control signal are data packets respectively.

[0078] It is understandable that the first preset control signal and the second preset control signal are not limited to fixed duty cycle signals or variable duty cycle signals, and can also be irregular data packets (such as password packets), which are not specifically limited here.

[0079] In some embodiments, after controlling the indoor unit according to the control instruction, the method also includes: when receiving a shutdown instruction, controlling the second sending unit to send a shutdown signal to the first receiving unit so that the outdoor unit enters a standby state according to the shutdown signal; controlling the first sending unit to stop sending the shutdown signal.

[0080] Specifically, when the user controls the air conditioner to shut down through the remote control (i.e., at time t5), the indoor unit control unit receives the shutdown command and controls the second sending unit to send a shutdown signal to the first receiving unit. The shutdown signal may be a preset data packet. When the outdoor unit control unit identifies the preset data packet, it controls the first sending unit to stop sending the second feedback signal and controls the third controllable switch unit to disconnect to stop providing power to the first charging unit, thereby realizing power off of the outdoor unit. Then the indoor unit control unit controls the first sending unit to stop sending the shutdown signal to disconnect the communication loop, thereby putting the air conditioner into a standby state.

[0081] In the above embodiment, when using Figure 1When using the air conditioner shown in the figure, the indoor unit only needs to send a shutdown signal to the outdoor unit to switch the power supply of the outdoor unit. There is no need to control the power supply of the outdoor unit through a high-power relay, thereby reducing the size of the indoor unit electronic control.

[0082] The technical solution of the present application is further described in detail below in conjunction with specific implementation methods:

[0083] When using Figure 1 When the air conditioner is Figure 5 As shown, the control method of the air conditioner includes:

[0084] S401, when the indoor unit is powered on, power is supplied to the display unit and a communication power supply is established.

[0085] S402, the indoor unit determines whether a control instruction is received. If the indoor unit receives the control instruction, step S403 is executed. If the indoor unit does not receive the control instruction, step S414 is executed.

[0086] S403: The indoor unit controls the second sending unit to send a wake-up signal to the first receiving unit according to the second preset control signal.

[0087] S404, the first controllable switch unit on the outdoor unit side switches based on the second preset control signal to charge the first electrolytic capacitor, and detects the voltage across the first electrolytic capacitor to obtain a voltage detection value, and the second receiving unit on the indoor unit side outputs a feedback signal that is the same as the second preset control signal.

[0088] S405, the outdoor unit determines whether the voltage detection value reaches a preset voltage threshold value. If the voltage detection value reaches the preset voltage value, step S406 is executed. If the voltage detection value does not reach the preset voltage value, the process returns to step S403.

[0089] S406, the outdoor unit controls the first end and the second end of the first relay to be attracted to turn off the first controllable switch unit, and controls the second relay to be attracted to provide power to the first charging unit.

[0090] S407: The outdoor unit controls the first sending unit to send a second feedback signal to the second receiving unit according to the first preset control signal, wherein the duty cycle of the first preset control signal is less than 1.

[0091] S408, the indoor unit determines whether the feedback signal is a superposition signal of the first preset control signal and the second preset control signal. If the feedback signal is a superposition signal of the first preset control signal and the second preset control signal, execute step S409; if the feedback signal is not a superposition signal of the first preset control signal and the second preset control signal, return to step S407.

[0092] S409: The indoor unit controls the indoor unit and the outdoor unit according to the control instruction.

[0093] S410, the indoor unit determines whether a shutdown command is received. If the indoor unit receives a shutdown command, step S411 is executed. If the indoor unit does not receive a shutdown command, the process returns to step S409.

[0094] S411, the indoor unit controls the second sending unit to send a shutdown signal to the first receiving unit.

[0095] S412: When the outdoor unit receives the shutdown signal, it controls the second relay to turn off, and controls the first sending unit to stop sending the second feedback signal.

[0096] S413, the indoor unit controls the second sending unit to stop sending the shutdown signal to disconnect the communication loop.

[0097] S414, the air conditioner enters the standby state.

[0098] In the above embodiment, during the outdoor unit wake-up process, the feedback signal is the same as the second preset control signal. After the outdoor unit completes the wake-up, the feedback signal is a superposition signal of the first preset control signal and the second preset control signal. Therefore, when the feedback signal satisfies the preset wake-up condition determined based on the first preset control signal and the second preset control signal, it can be determined that the outdoor unit completes the wake-up, thereby achieving accurate judgment of whether the outdoor unit completes the wake-up, thereby improving the reliability of the air conditioner; and when using Figure 1 When using the air conditioner shown in the figure, the indoor unit only needs to send a shutdown signal to the outdoor unit to switch the power supply of the outdoor unit. There is no need to control the power supply of the outdoor unit through a high-power relay, thereby reducing the size of the indoor unit electronic control.

[0099] In summary, according to the control method of the air conditioner of an embodiment of the present invention, when the indoor unit is powered on and receives a control instruction, the second sending unit is controlled according to the second preset control signal to send a wake-up signal to the first receiving unit to turn on the first controllable switch unit, and when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, it is determined that the outdoor unit has completed the wake-up, and the indoor unit is controlled according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, the outdoor unit includes a first receiving unit, a first controllable switch unit, a second controllable switch unit, a first sending unit and a first charging unit, the indoor unit includes a second sending unit and a second receiving unit, and the first sending unit is configured to send a second feedback signal to the second receiving unit according to the first preset control signal after the first controllable switch unit is disconnected, so as to establish communication with the indoor unit. Therefore, because the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, and the first sending unit sends the second feedback signal to the second receiving unit based on the first preset control signal after the outdoor unit completes the wake-up, the feedback signal output by the second receiving unit can meet the preset wake-up condition only after receiving the correct second feedback signal. Therefore, when the feedback signal meets the preset wake-up condition, it can be determined that the outdoor unit has completed the wake-up, thereby achieving accurate judgment on whether the outdoor unit has completed the wake-up, thereby improving the reliability of the air conditioner.

[0100] Corresponding to the above embodiments, an embodiment of the present invention further provides a computer-readable storage medium on which a control program for an air conditioner is stored.

[0116] It should be noted that the specific implementation of the air conditioner in the embodiment of the present invention corresponds one to one with the specific implementation of the control method of the air conditioner in the aforementioned embodiment of the present invention, and will not be described in detail herein.

[0117] In summary, according to an embodiment of the air conditioner of the present invention, when the indoor unit is powered on and a control instruction is received, the indoor unit control unit controls the second sending unit to send a wake-up signal to the first receiving unit according to the second preset control signal to turn on the first controllable switch unit, and when it is detected that the feedback signal output by the second receiving unit meets the preset wake-up condition, it is determined that the outdoor unit has completed the wake-up, and the indoor unit is controlled according to the control instruction, wherein the preset wake-up condition is determined based on the first preset control signal and the second preset control signal, the outdoor unit includes a first receiving unit, a first controllable switch unit, a second controllable switch unit, a first sending unit and a first charging unit, the indoor unit includes a second sending unit and a second receiving unit, and the first sending unit is configured to send a second feedback signal to the second receiving unit according to the first preset control signal after the first controllable switch unit is disconnected, so as to establish communication with the indoor unit.
