[ second embodiment ]
The second embodiment of the present invention provides a power cut-off control method for an air conditioner, which is applied to the power cut-off control circuit 100 in the first embodiment, and by the power cut-off control method of the present embodiment, the operation efficiency of the air conditioner is improved, and the power consumption of the outdoor unit in the standby state is improved.
Preferably, referring to fig. 4, when the air conditioner receives a power-on operation instruction, the power cut-off control circuit 100 is in a power-on wake-up state; in the power shutoff control circuit 100, the first relay 11, the second relay 13, and the outdoor unit circuit 80 are operated as follows:
for example, at time T1, the air conditioner receives the turn-on command, the indoor unit power switch 40 is turned on, and the turn-on command is transmitted to the indoor unit communication module 30 by the indoor unit controller 20, and then the indoor unit communication module 30 transmits the turn-on signal to the power cut-off device 10 and the outdoor unit circuit 80, because a certain transmission time exists during the transmission of the signal, there is a certain delay between the indoor unit circuit 50 and the outdoor unit circuit 80 receiving the command, so when the air conditioner receives the turn-on command, that is, at time T1, the indoor unit circuit 50 and the outdoor unit circuit 80 do not operate immediately, and because the turn-on command of the air conditioner is transmitted to the indoor unit circuit 50 first and then to the outdoor unit circuit 80, the delay of the indoor unit communication module 30 and the outdoor unit communication module 84 responding to the command is different.
Specifically, before the time T1, since the power system does not supply power, the control circuit 100 has no power supply, and both the indoor circuit 50 and the outdoor circuit 80 are in the power-off state, that is, both the indoor circuit 50 and the outdoor circuit 80 do not work; when the control circuit 100 is powered on at time T1 (i.e., the indoor unit circuit 50 is powered on), the air conditioning system enters a power-on wake-up state (time T1 to time T3, i.e., the outdoor unit circuit 80 is set to be turned on at time T3); after the indoor unit is powered on at the time T1, the first relay 11 is immediately controlled to be closed, that is, the first relay 11 is turned on, at this time, since the first live wire connection end 60 is connected with the live wire output end 61 through the wire, and the outdoor unit circuit 80 is electrically connected with the live wire output end 61, the outdoor unit circuit 80 is powered on at this time, and the outdoor unit circuit 80 is in a wake-up state at this time.
Further, after the first relay 11 is turned on and lasts for K seconds, and when time T2 is reached, the second relay 13 is controlled to be closed, the first relay 11 is controlled to still maintain the on state at this time, and after time T2, the outdoor unit circuit 80 is formally powered, and meanwhile, the outdoor unit circuit 80 enters the preparation state before normal operation at this time.
Further, after the indoor unit circuit 50 continues to operate for M seconds, the time T3 is reached, at this time, the first relay 11 is controlled to be switched off, only the second relay 13 is switched on at the moment of the outdoor unit circuit 80, and meanwhile, the outdoor unit circuit 80 enters a normal working state; at this time, the control circuit 100 completes the wake-up state and enters the normal operation state, and normal communication is formed between the indoor circuit 50 and the outdoor circuit 80 to exchange data.
Preferably, after time T3, the control circuit 100 enters a remote control waiting state: when the control circuit 100 is in the wait remote control state: further acquiring remote control information of the air conditioner, wherein the remote control information of the air conditioner can comprise a remote control starting signal and a low-power consumption standby state; wherein, if the control circuit 100 is in the process of waiting for the remote control state: when the remote control state lasts for R seconds and the control circuit 100 receives a remote control start signal, the control circuit 100 enters a normal working state, the first relay 11 and the second relay 13 keep the original states unchanged, that is, at this time, the first relay 11 is still in a disconnected state, and the second relay 13 is still in a connected state.
Further, if the control circuit 100 waits for the remote control state for R seconds and does not receive the remote control start signal, the air conditioner enters a low power consumption standby state, and at this time, the indoor unit circuit 50 controls the second relay 13 to be switched off; that is, after the air conditioner enters the low power consumption standby state, the first relay 11 and the second relay 13 are simultaneously in the off state, and the outdoor unit circuit 80 is also in the off state at this time.
Further still, during the low standby power consumption state, if the indoor unit circuit 50 receives the remote control power-on signal, the control circuit 100 enters the remote control wake-up stage again: for example, the control circuit 100 enters a low power consumption standby state at time T4, and both the indoor unit circuit 50 and the outdoor unit circuit 80 are in an off state at this time; when the power-on instruction is received again at the time of T6, the control circuit 100 enters the remote control wake-up stage again; at this time, the first relay 11 in the power shutoff device 10 is controlled to be turned on again, and after the on time of the first relay 11 lasts for K seconds (that is, the time T7 is reached), the indoor unit circuit 50 controls the second relay 13 to be turned on; until the on-time of the first relay 11 continues for M seconds (i.e. the time T8 is reached), the indoor unit circuit 50 controls the first relay 11 to turn off; the control circuit 100 completes the remote wake-up phase again and enters the normal operating state again.
In the embodiment of the present invention, in the power supply interruption control circuit 100 in the air conditioner, the state of the control circuit 100 can be summarized as: a normal running state, a remote shutdown state and a low standby power consumption state. Because the low standby power consumption state needs to control the on/off of the power supply for some parts (such as the first relay 11 and the second relay 13), a remote-control power-off state is often set between the normal operation state and the low standby power consumption state, so as to prevent the first relay 11 and the second relay 13 from being frequently switched on/off when the client performs the remote-control power-off in a short time and immediately turns on the power supply again. The low standby power consumption state is entered when the remote control power-off state is entered into the low standby power consumption state (because the relay has a switch time life limit), and the remote control power-on state is not received until a period of time (currently, 3 minutes, namely 180 seconds is often set).
Preferably, during the normal working period of the air conditioning system, a remote control shutdown signal is received; for example, when the air conditioner normally operates and the air conditioner reaches the time T10, the control circuit 100 enters the remote-control shutdown state after receiving the remote-control shutdown signal.
Specifically, at time T10, if the remote-control power-off state lasts for R seconds (i.e., time T11 is reached), the air conditioner receives the remote-control power-on signal, the control circuit 100 enters a normal operating state (does not enter a low standby power consumption state and a remote-control wake-up state) according to a remote-control instruction, and the first relay 11 and the second relay 13 continue to keep the original states unchanged; if the remote control receiving state lasts for R seconds, the air conditioner does not receive a remote control starting signal, the control circuit 100 enters a low power consumption standby state, and at the time of T11, the indoor unit circuit 50 controls the second relay 13 to be switched off, so that the air conditioning system enters the low standby state; further, during the low standby power consumption state, if the indoor unit circuit 50 receives a remote control startup signal, a remote control wake-up stage is entered; for example, the time when the remote control startup signal is received is T12, and from the time T12, the indoor unit circuit 50 controls the first relay 11 to be turned on, and at the same time, after the on time of the first relay 11 lasts for K seconds (that is, the time T13 is reached), the indoor unit circuit 50 controls the second relay 13 to be turned on, and when the on time of the first relay 11 continues for M seconds (that is, the time T14 is reached), the indoor unit circuit 50 controls the first relay 11 to be turned off; the control circuit 100 completes remote control wakeup and enters a normal working state.
It should be noted that, in fig. 4, in T1 to T3, the air conditioner is in the power-on wake-up mode, and in T3 to T4, the air conditioner is in the state of waiting for remote control; in T4-T6, the air conditioner is in a low-power standby state; in T6-T8, the air conditioner is in a remote control awakening state; in the T8-T10, the air conditioner is in a normal operation state; in the T10-T11, the air conditioner is in a remote control shutdown state; in T11-T12, the air conditioner is in a low-power standby state; in T12-T14, the air conditioner is in a remote control wake-up state.
Specifically, in T1-T3, when the air conditioner is in the power-on wake-up mode, the indoor unit is in the power-on wake-up state in T1-T2, in T2-T3, the outdoor unit is in the power-on wake-up state, and at time T2, the indoor unit is woken up, the indoor unit circuit 50 is turned on, at time T3, the outdoor unit is woken up, and the outdoor unit circuit 80 is turned on; in T3 to T4, the air conditioner is in a standby remote control state in which the air conditioner can be adjusted according to the user's needs, wherein when the air conditioner is in the standby remote control state, the first relay 11 is in an off state, the second relay 13 is in an on state, and when the air conditioner is in the standby remote control state, the first information transmission line 23, the first information receiving line 24, the second information receiving line 88, and the second information transmission line 87 can normally receive or transmit signals in the indoor unit circuit 50 and the outdoor unit circuit 80.
Further, in T4 to T6, when the air conditioner is in the warm-stop state or the low-power standby state, in order to reduce power consumption in the control circuit 100 at this time, the first relay 11 and the second relay 13 are controlled to be turned off, and the corresponding indoor unit circuit 50 and the corresponding outdoor unit circuit 80 are in the off state at this time, and no signal is transmitted through the first information transmission line 23, the first information reception line 24, the second information reception line 88, and the second information transmission line 87.
Further, when the air conditioner is in a remote control wake-up mode (i.e. remote control start-up) in T6-T8, the indoor unit is in a remote control wake-up state in T6-T7, and the outdoor unit is in a remote control wake-up state in T7-T8, and at the time of T7, the indoor unit is woken up, the indoor unit circuit 50 is turned on, and at the time of T8, the outdoor unit is woken up, and the outdoor unit circuit 80 is turned on; at time T6, the first relay 11 is in the on state, and at time T7, the second relay 13 is in the on state.
Further, at T8-T10, because the indoor unit and the outdoor unit are simultaneously awakened by remote control, the air conditioner normally operates, at this time, the first relay 11 is switched off, and the second relay 13 is continuously in a conducting state; at T10-T11, if the air conditioner receives a remote control shutdown signal, in order to ensure that the frequent shutdown and startup of the air conditioner occur in a short time, the air conditioner enters a remote control shutdown state, namely the shutdown time of the air conditioner is delayed, and the air conditioner is still in a normal working state; until the time T11, the air conditioner completes the remote control shutdown, and enters the low-power standby state again, until the time T12 is reached, the air conditioner is awakened remotely again, wherein, at the time T7-T11, the first information transmission line 23, the first information receiving line 24, the second information receiving line 88 and the second information transmission line 87 can normally receive or transmit signals in the indoor unit circuit 50 and the outdoor unit circuit 80; at T11 to T14, the operation state of the air conditioner and the cut-off state of the first relay 11 and the second relay 13 are the same as the operation state of the air conditioner at T4 to T8 and the cut-off state of the first relay 11 and the second relay 13, and the description thereof is not repeated here.
