[0049] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described below in connection with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0050] The present application will be described below in connection with Figures 1-4 A relay-based power saving method, device, equipment and air conditioner are described in the present application. By controlling the relay to disconnect the power supply path, and by determining that the current state of the outdoor unit is a power-off state to verify that the outdoor unit has been powered off, not only can the power consumption be saved, but also the safety hazards of the outdoor unit being powered on can be avoided.

[0051] An air conditioner, comprising an indoor unit, an outdoor unit and a controller, a power supply loop and a communication loop are arranged between the indoor unit and the outdoor unit, and a relay is arranged on the power supply loop side of the indoor unit.

[0052] As Figure 1 shown, it is an implementation flow schematic view of a relay-based power saving method provided by an embodiment of the present application. A relay-based power saving method can include but is not limited to steps S100 to S400.

[0053] S100, in the case where the indoor unit receives a standby instruction, a circuit disconnection signal is generated;

[0054] S200, based on the circuit disconnection signal, the relay is controlled to be disconnected to disconnect the power supply loop;

[0055] S300, in the case where the relay responds to the circuit disconnection signal, an inquiry request signal is sent to the outdoor unit through the communication loop, and an answer signal corresponding to the inquiry request signal returned by the outdoor unit is waited for;

[0056] S400, in the case where the answer signal returned by the outdoor unit is not received, it is determined that the current state of the outdoor unit is a power-off state.

[0057] It should be noted that the execution subject of the relay-based power saving method of the embodiments of the present application can be a hardware device with data information processing capability and / or necessary software required to drive the hardware device to work.

[0058] Alternatively, the execution subject can include but is not limited to a workstation, a server, a computer, a user terminal and other intelligent devices. Among them, the user terminal includes but is not limited to a mobile phone, a computer, a smart voice interactive device, a smart home appliance, a vehicle-mounted terminal, etc.

[0059] In step S100 of some embodiments, in the case where the indoor unit receives a standby instruction, a circuit disconnection signal is generated.

[0060] It can be understood that when the user controls the air conditioner to be in standby mode by voice or remote controller, or when the air conditioner senses that the user has left the room for a certain length of time and automatically adjusts to standby mode, the air conditioner will automatically generate a standby instruction to control the air conditioner to enter standby mode according to the standby instruction. At this time, the indoor unit of the air conditioner generates a circuit disconnection signal to disconnect the circuit loop according to the circuit disconnection signal, thereby achieving energy saving and power saving.

[0061] In step S200 of some embodiments, based on the circuit disconnection signal, the relay is controlled to be disconnected to disconnect the power supply loop.

[0062] It should be noted that the relay includes an input relay and an output relay.

[0063] The input relay and the output relay can be replaced according to requirements. The input relay is used to pass the current through the input circuit connected with the input relay from the indoor unit to the outdoor unit.

[0064] The output relay is used to pass the current at the outdoor unit through the output circuit connected with the output relay from the outdoor unit to the indoor unit.

[0065] It can be understood that after the step of generating a circuit disconnection signal in the case where the indoor unit receives a standby instruction in step S100 is executed, the specific execution step can be to issue the circuit disconnection signal to the indoor unit.

[0066] The circuit disconnection signal received by the indoor unit is classified and processed to obtain an input disconnection signal and an output disconnection signal.

[0067] The input disconnection signal is sent to the input relay to control the input relay to be disconnected according to the input disconnection signal to disconnect the corresponding input circuit.

[0068] The output disconnect signal is sent to an output relay to control the output relay to disconnect according to the output disconnect signal to disconnect a corresponding output circuit.

[0069] The circuit disconnect signal is sent to the indoor unit by the controller, and the circuit disconnect signal received by the indoor unit is classified and processed based on the function of the relay to obtain an input disconnect signal and an output disconnect signal.

[0070] In the embodiments of the present application, one input circuit and one output circuit, one input relay and one output relay are taken as examples, that is, the output disconnect signal is sent to the output relay to control the output relay to disconnect according to the output disconnect signal to isolate the output circuit corresponding to the output relay.

[0071] The input disconnect signal is sent to the input relay to control the input relay to disconnect according to the input disconnect signal to disconnect the input circuit corresponding to the input relay.

[0072] When there are multiple input circuits or multiple output circuits, the execution method of controlling the input relay to disconnect or controlling the output relay to disconnect is the same as that of a single one, which will not be described here.

[0073] In step S300 of some embodiments, in the case that the relay responds to the circuit disconnect signal, an inquiry request signal is sent to the outdoor unit through the communication loop, and an answer signal corresponding to the inquiry request signal returned by the outdoor unit is waited for.

[0074] It can be understood that after the step of controlling the relay to disconnect to disconnect the power supply circuit based on the circuit disconnect signal in step S200 is executed, the specific execution step can be that in the case that the relay responds to the circuit disconnect signal, an inquiry request signal is sent to the outdoor unit through the communication loop, and an answer signal corresponding to the inquiry request signal returned by the outdoor unit is waited for. To verify whether the outdoor unit is truly powered off.

[0075] In step S400 of some embodiments, in the case that the answer signal returned by the outdoor unit is not received, it is determined that the current state of the outdoor unit is a powered-off state.

[0076] It can be understood that after the step of sending an inquiry request signal to the outdoor unit through the communication loop in the case that the relay responds to the circuit disconnect signal and waiting for an answer signal corresponding to the inquiry request signal returned by the outdoor unit in step S300 is executed, the specific execution step can be that the waiting time for waiting for the answer signal to be returned is obtained.

[0077] In a case where the waiting duration exceeds a preset duration threshold and the response signal returned by the outdoor unit is not received, it is determined that the communication loop is in a disconnected state.

[0078] Based on the disconnected state of the communication loop, it is determined that the outdoor unit is in the powered-off state.

[0079] Further, a waiting duration for waiting for a response signal is obtained, and the waiting duration and a preset duration threshold are compared. In a case where the waiting duration exceeds the preset duration threshold and the response signal returned by the outdoor unit is not received, it is determined that the communication loop is in a disconnected state.

[0080] In a case where the waiting duration exceeds the duration threshold and the response signal returned by the outdoor unit is received, it is indicated that the communication loop is still in a connected state, i.e., the circuit loop between the outdoor unit and the indoor unit is in a powered-on state.

[0081] Because the communication loop needs to be supported by the current at the outdoor unit to maintain normal communication between the outdoor unit and the indoor unit.

[0082] Generally, when the communication loop is in a disconnected state, it is proved that the outdoor unit is in a powered-off state, and thus the communication loop between the outdoor unit and the indoor unit is in a disconnected state. However, in order to avoid an abnormality of the communication loop in the powered-off state, the accuracy of determining that the outdoor unit is in the powered-off state is improved.

[0083] Therefore, in a case where the communication loop is in the disconnected state, a circuit closing signal is generated to control the power supply loop to be closed according to the circuit closing signal.

[0084] It should be noted that the circuit closing signal includes an input circuit closing signal and an output circuit closing signal.

[0085] According to the input circuit closing signal, the input relay is controlled to be closed, so that the input circuit corresponding to the input relay is closed.

[0086] According to the output circuit closing signal, the output relay is controlled to be closed, so that the output circuit corresponding to the output relay is closed. In a case where the input circuit and the output circuit are both closed, the power supply loop can be controlled to be closed.

[0087] In order to further determine whether the communication loop is abnormal, the accuracy of determining that the outdoor unit is in the powered-off state is improved.

[0088] In the case that the power loop is closed, the communication state of the communication loop is determined to be normal or abnormal. In the case that the communication state of the communication loop is normal, the input circuit and the output circuit are controlled to be in the open state.

[0089] In the case that the communication state of the communication loop is normal, a new circuit opening signal is generated, and the input circuit and the output circuit are controlled to be in the open state according to the new circuit opening signal.

[0090] In the case that the communication state of the communication loop is normal, a new circuit opening signal is generated, and the input circuit and the output circuit are controlled to be in the open state according to the new circuit opening signal.

[0091] Thus, in the case that the communication state of the communication loop is normal and the input circuit and the output circuit are in the open state, it can be determined that the outdoor unit is in the power-off state. If the outdoor unit is in the power-off state, power saving can be achieved.

[0092] In some embodiments of the present application, after the step of determining whether the communication state of the communication loop is normal, the method further comprises:

[0093] In the case that the communication state of the communication loop is abnormal, a warning information is generated;

[0094] The warning information is sent to a preset display area to display the warning information on the display area to achieve warning.

[0095] It can also be understood that, in the case that the communication state of the communication loop is abnormal, a warning information is generated, which indicates that the communication loop between the outdoor unit and the indoor unit is abnormal and needs to be repaired. The warning information is sent to a preset display area to display the warning information on the display area to achieve warning.

[0096] Figure 2 is one of the structural schematic diagrams of the power saving device based on a relay provided by the present application, Figure 2 The dashed line shown in the middle is the communication loop between the indoor unit and the outdoor unit. K1 is an input relay, K2 is an output relay, and of course K1 and K2 can be interchanged. The connection between the outdoor unit and K1 of the indoor unit is the input circuit, and the connection between the outdoor unit and K2 of the indoor unit is the output circuit. The input circuit, the output circuit, the outdoor unit and the indoor unit together form a circuit loop.

[0097] In some embodiments of the present invention, when the indoor unit receives a standby command, the indoor unit's main control MCU controls relays K1 and K2 to disconnect, at which point the outdoor unit is in a power-off state and consumes no energy. At this time, the indoor unit is only connected to sensors and a fan, with the fan stopped. Thus, the entire air conditioner control system achieves low standby power consumption.

[0098] During standby mode, the indoor unit cannot establish communication with the outdoor unit, nor is it necessary to do so. When the indoor unit receives a machine start command, the indoor unit's MCU controls relays K1 and K2 to close, closing the power circuit for the outdoor unit, and the outdoor unit begins operation. At this time, the communication line ( Figure 2 The dotted line (in the diagram) can form a closed loop with the output power line. The outdoor unit then begins to establish communication with the indoor unit.

[0099] The indoor unit reports communication faults based on whether the air conditioning system is in standby mode. When both the indoor and outdoor units are operating, the indoor unit cannot establish communication with the outdoor unit, indicating a communication fault between them. When the air conditioning system is in standby mode, the outdoor unit is powered off, and the indoor unit cannot establish communication with the outdoor unit. The indoor unit then determines that the unit is in standby mode and does not report a communication fault.

[0100] This invention provides a relay-based energy-saving method, apparatus, device, and air conditioner. When the indoor unit receives a standby command, it generates a circuit disconnect signal. Based on the circuit disconnect signal, it controls the relay to disconnect the power supply circuit. When the relay responds to the circuit disconnect signal, it sends an inquiry request signal to the outdoor unit through the communication circuit and waits for a response signal from the outdoor unit corresponding to the inquiry request signal. If no response signal is received from the outdoor unit, the current state of the outdoor unit is determined to be a power-off state. By controlling the relay to disconnect the power supply path and verifying that the outdoor unit is powered off by determining its current state, not only can electricity be saved, but the safety hazards of keeping the outdoor unit powered on are also avoided.

When the relay responds to the circuit disconnecting signal, an inquiry request signal is sent to the outdoor unit through the communication circuit, and an answer signal corresponding to the inquiry request signal returned by the outdoor unit is waited.
