[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Combine the following Figure 1-Figure 4 The present invention describes a relay-based power saving method, device, equipment and air conditioner, which disconnects the power path based on the control of the relay and verifies that the outdoor unit has been powered off by determining that the current state of the outdoor unit is a power-off state, which can not only save electricity but also avoid safety hazards when the outdoor unit is powered on.

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

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

[0053] S100, generating a circuit disconnection signal when the indoor unit receives a standby command;

[0054] S200, based on the circuit disconnection signal, controlling the relay to disconnect to disconnect the power supply circuit;

[0055] S300, when the relay responds to the circuit disconnection signal, sending an inquiry request signal to the outdoor unit through the communication circuit, and waiting for a response signal corresponding to the inquiry request signal returned by the outdoor unit;

[0056] S400: When the response signal returned by the outdoor unit is not received, determining that the current state of the outdoor unit is a power-off state.

[0057] It should be noted that the executor of the relay-based power saving method of the embodiment of the present application may be a hardware device with data information processing capabilities and / or the necessary software required to drive the hardware device to work.

[0058] Optionally, the execution subject may include but is not limited to workstations, servers, computers, user terminals and other intelligent devices. Among them, user terminals include but are not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, etc.

[0059] In step S100 of some embodiments, when the indoor unit receives a standby command, a circuit disconnection signal is generated.

[0060] It can be understood that when the user controls the air conditioner to standby mode through voice or remote control, or when the air conditioner senses that the user has left the room for a certain period of time and the air conditioner automatically adjusts to standby mode, a standby instruction will be automatically generated inside the air conditioner to control the air conditioner to enter the standby mode according to the standby instruction. At this time, the indoor unit of the air conditioner automatically generates a circuit disconnect signal to disconnect the circuit loop according to the circuit disconnect 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 circuit.

[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 demand. The input relay is used to pass the current from the indoor unit to the outdoor unit through the input circuit connected to the input relay.

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

[0065] It can be understood that after executing step S100 of generating a circuit disconnection signal when the indoor unit receives a standby instruction, the specific execution step may be sending the circuit disconnection signal to the indoor unit;

[0066] Classifying and processing the circuit disconnection signal received by the indoor unit to obtain an input disconnection signal and an output disconnection signal;

[0067] Sending the input disconnection signal to the input relay, so as to control the input relay to disconnect according to the input disconnection signal to disconnect the corresponding input circuit;

[0068] The output disconnection signal is sent to the output relay, so as to control the output relay to disconnect according to the output disconnection signal to disconnect the corresponding output circuit.

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

[0070] In an embodiment of the present invention, taking an example in which there is one input circuit, one output circuit, one input relay, and one output relay, the output disconnect signal is sent to the output relay to control the output relay to disconnect according to the output disconnect signal, so as to isolate the output circuit corresponding to the output relay.

[0071] The input disconnection signal is sent to the input relay, so as to control the input relay to be disconnected according to the input disconnection signal, so as 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 the output relay to disconnect is the same as that of a single one, and will not be repeated here.

[0073] In step S300 of some embodiments, when the relay responds to the circuit disconnection signal, an inquiry request signal is sent to the outdoor unit through the communication loop, and a response signal corresponding to the inquiry request signal returned by the outdoor unit is waited.

[0074] It is understandable that after executing step S200 of controlling the relay to disconnect to disconnect the power circuit based on the circuit disconnection signal, the specific execution step may be sending an inquiry request signal to the outdoor unit through the communication circuit when the relay responds to the circuit disconnection signal, and waiting for a response signal corresponding to the inquiry request signal returned by the outdoor unit, so as to verify whether the outdoor unit is actually powered off.

[0075] In step S400 of some embodiments, when the response 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.

[0076] It can be understood that after executing step S300 of sending an inquiry request signal to the outdoor unit through the communication loop and waiting for a response signal corresponding to the inquiry request signal returned by the outdoor unit when the relay responds to the circuit disconnection signal, the specific execution step may be obtaining a waiting time for waiting for the response signal to be returned;

[0077] When the waiting time exceeds a preset time threshold and the response signal returned by the outdoor unit is not received, determining that the communication circuit is in a disconnected state;

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

[0079] Furthermore, the waiting time for waiting for the return response signal is obtained, and the waiting time is compared with a preset time threshold. When the waiting time exceeds the preset time 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] When the waiting time exceeds the time threshold and a response signal returned by the outdoor unit is received, it indicates that the communication loop is still in the on state, that is, the circuit loop between the outdoor unit and the indoor unit is energized.

[0081] Because of the communication loop, if you want to communicate normally, you must ensure that there is normal current flow at the outdoor unit, that is, 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] Usually, when the communication circuit is disconnected, it can be proved that the outdoor unit is in a power-off state, so the communication circuit between the outdoor unit and the indoor unit is disconnected. However, in order to avoid abnormalities in the communication circuit during power outage, the accuracy of judging whether the outdoor unit is in a power-off state is improved.

[0083] Therefore, when the communication circuit is in the disconnected state, a circuit closing signal is generated to control the power circuit 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 close, thereby closing the input circuit corresponding to the input relay.

[0086] According to the output circuit closing signal, the output relay is controlled to close, thereby closing the output circuit corresponding to the output relay. When both the input circuit and the output circuit are closed, the power supply circuit can be controlled to close.

[0087] In order to further determine whether the communication circuit is abnormal, the accuracy of determining whether the outdoor unit is in a power-off state can be improved.

[0088] When the power supply circuit is closed, it is determined whether the communication state of the communication circuit is normal. Specifically, data may be transmitted between the indoor unit and the outdoor unit using the communication circuit to determine whether the communication state of the communication circuit is normal.

[0089] When it is determined that the communication state of the communication loop is the normal state, a new circuit disconnection signal is generated, and according to the new circuit disconnection signal, the input circuit and the output circuit are controlled to be in a disconnection state.

[0090] When it is determined that the communication state of the communication loop is in a normal state, a new circuit disconnection signal is generated, so as to control the input circuit and the output circuit to be in a disconnected state according to the new circuit disconnection signal.

[0091] In this way, when the communication state of the communication circuit is normal and the input circuit and the output circuit are both disconnected, it can be accurately 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 invention, after the step of determining whether the communication state of the communication loop is normal, the method further includes:

[0093] generating warning information when it is determined that the communication state of the communication circuit is an abnormal state;

[0094] The warning information is sent to a preset display area, so that the warning information is displayed in the display area to implement the warning.

[0095] It can also be understood that, when it is determined that the communication state of the communication circuit is abnormal, an early warning message is generated, indicating that the communication circuit between the outdoor unit and the indoor unit is abnormal and needs to be repaired, and the early warning message is sent to a preset display area, so that the early warning message is displayed in the display area to implement early warning.

[0096] Figure 2 This is one of the structural schematic diagrams of the relay-based power saving device provided by the present invention. Figure 2 The dotted line in the middle shows the communication circuit between the indoor unit and the outdoor unit. K1 is the input relay and K2 is the output relay. Of course, K1 and K2 can be interchanged. The connection between K1 of the outdoor unit and the indoor unit is the input circuit, and the connection between K2 of the outdoor unit and the indoor unit is the output circuit. The input circuit, output circuit, outdoor unit and 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 main control MCU controls relays K1 and K2 to disconnect, and the outdoor unit is in a power-off state and does not consume any energy. At this time, the indoor unit is only connected to a sensor and a fan, and the fan is in a stopped state. At this time, the entire air conditioner control system achieves low standby power consumption.

[0098] During the low standby period of the air conditioner, the indoor unit cannot establish communication with the outdoor unit, nor does it need to establish communication. When the indoor unit receives the machine operation command, the indoor unit MCU controls relays K1 and K2 to close, the power circuit of the outdoor unit is closed, and the outdoor unit starts to work. At this time, the communication line ( Figure 2 The dotted line in the figure can form a closed loop with the output power line. The outdoor unit starts to establish communication with the indoor unit.

[0099] The indoor unit reports the indoor and outdoor unit communication fault according to whether the air conditioning system is in standby mode. When both the indoor and outdoor units are in working mode, the indoor and outdoor units cannot establish communication, indicating that there is a communication fault between the outdoor and indoor units. When the air conditioning system is in standby mode, the outdoor unit is powered off, and the indoor and outdoor units cannot establish communication. The indoor unit determines that the unit is in standby mode and does not report the indoor and outdoor unit communication fault.

[0100] The present invention provides a relay-based power saving method, device, equipment and air conditioner, which generates a circuit disconnection signal when the indoor unit receives a standby command; based on the circuit disconnection signal, controls the relay to disconnect to disconnect the power circuit; when the relay responds to the circuit disconnection signal, sends an inquiry request signal to the outdoor unit through the communication circuit, and waits for a response signal corresponding to the inquiry request signal returned by the outdoor unit; when the response signal returned by the outdoor unit is not received, determines that the current state of the outdoor unit is a power-off state. By disconnecting the power path based on the control of the relay, 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 electricity be saved, but also potential safety hazards when the outdoor unit is powered on can be avoided.
