[0028] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0029] FIG1 is a flow chart of a method for controlling an air conditioner operation mode according to the present invention.

[0030] In order to further introduce the air conditioner operation mode control method provided in this application, it will be explained below with reference to FIG1 .

[0031] In an exemplary embodiment of the present application, as can be seen from FIG. 1 , the air conditioner operation mode control method may include step 110 and step 120 , and each step will be described below.

[0032] In step 110, when the signal receiving module receives the notice of utility power restriction, the signal receiving module is controlled to send an energy-saving instruction to the indoor unit based on the inherent signal transmission channel between the outdoor unit and the indoor unit of the air conditioner.

[0033] In step 120, when the indoor unit receives the energy-saving instruction, the air conditioner is automatically adjusted to operate in the energy-saving mode.

[0034] The signal receiving module is powered by the outdoor unit, the mains power restriction notification is sent by the signal sending module, and the signal sending module is powered by the mains.

[0035] In one embodiment, the signal receiving module may be installed on an outdoor unit of an air conditioner, wherein the power supply of the signal receiving module may be a power supply from the outdoor unit.

[0036] In another embodiment, when the signal receiving module receives a notice of a power restriction on the mains, it indicates that the mains power grid cannot supply power normally. In order to ensure the normal operation of other electrical appliances, the operation mode of the air conditioner needs to be adjusted to an energy-saving mode.

[0037] During application, to save component costs, the signal receiving module can be controlled to send energy-saving instructions to the indoor unit based on the signal transmission channel. The signal transmission channel is a signal transmission channel inherent to the indoor and outdoor units of the air conditioner. In this embodiment, by multiplexing the signal transmission channel, the energy-saving instructions can be sent to the indoor unit without increasing any cost. Therefore, when the indoor unit receives the energy-saving instruction, it can automatically adjust the air conditioner to operate in energy-saving mode.

[0038] In another exemplary embodiment of the present application, if there are multiple air conditioners, a signal receiving module can be configured for each outdoor unit of the air conditioner. Based on the signal receiving module, the module can send energy-saving instructions and / or instructions to operate according to the current operating mode to the corresponding outdoor unit. This embodiment allows for independent control of each air conditioner, ensuring that its operation is not interfered with by the operation of other air conditioners. Furthermore, configuring a signal receiving module for each outdoor unit allows for precise control of each air conditioner.

[0039] It should be noted that the air conditioner's power supply can be derived from a regular indoor power outlet, which can be powered by mains electricity to ensure the air conditioner's continued effective operation. The signal transmission module is powered by mains electricity. In practice, a signal receiving module can be installed next to each air conditioner's outdoor unit, or multiple air conditioner outdoor units can share a single signal receiving module. This application does not impose a specific limit on the number of signal receiving modules.

[0040] In another example, there may be one or more signal sending modules, and the number of the signal sending modules is not specifically limited in this application.

[0041] The present application provides an air conditioner operating mode control method. When a signal receiving module receives a notice of utility power curtailment, the signal receiving module is controlled to send an energy-saving instruction to the indoor unit of the air conditioner via the inherent signal transmission channel between the outdoor and indoor units. Upon receiving the energy-saving instruction, the indoor unit automatically adjusts the air conditioner to operate in energy-saving mode. In this application, the signal receiving module reuses the signal transmission channel to send the energy-saving instruction to the indoor unit of the air conditioner, and controls the air conditioner to operate in energy-saving mode based on the energy-saving instruction. This achieves low-cost automatic control of air conditioner operation and improves user experience and satisfaction during use.

[0042] FIG2 is a second flow chart of the air conditioner operation mode control method provided in the present application.

[0043] In order to further introduce the air conditioner operation mode control method provided in this application, it will be explained below with reference to FIG. 2 .

[0044] In an exemplary embodiment of the present application, in combination with Figure 2, it can be seen that the air conditioner operation mode control method may include steps 210 to 240, wherein steps 210 to 220 are the same or similar to steps 110 to 120. Please refer to the previous description for its specific implementation and beneficial effects. They will not be repeated in this embodiment. Steps 230 and 240 will be introduced below respectively.

[0045] In step 230, if the signal receiving module does not receive the mains power limit notification, the control signal receiving module sends an instruction to operate in accordance with the current operating mode to the indoor unit based on the signal transmission channel;

[0046] When the indoor unit receives an instruction to operate in accordance with the current operation mode, the air conditioner is controlled to continue operating in accordance with the current operation mode.

[0047] In one embodiment, if the signal receiving module does not receive a notice of mains power restriction, it indicates that the mains can normally power the electrical appliances. In this scenario, there is no need to limit the operating mode of the air conditioner. During application, the signal receiving module can be controlled to send instructions to the indoor unit to operate in accordance with the current operating mode based on the signal transmission channel. Furthermore, if the indoor unit receives instructions to operate in accordance with the current operating mode, it can control the air conditioner to operate in accordance with the current operating mode. Through this embodiment, it can be ensured that when the mains power grid has sufficient power supply, the air conditioner can operate according to the user's settings, thereby improving the user experience and satisfaction.

[0048] In another exemplary embodiment of the present application, the signal receiving module and the signal sending module may transmit the mains power restriction notification in a power line carrier communication manner.

[0049] It should be noted that in order to ensure that the transmission of the mains power restriction notification will not be interfered with by other factors, such as whether the WIFI communication signal is good or whether the infrared transmission distance is close enough, during the application process, the mains power restriction notification can be transmitted based on power line carrier communication.

[0050] In one embodiment, high-voltage power lines, medium-voltage power lines, or low-voltage distribution lines can be used as information transmission media instead of WIFI or infrared transmission as information (e.g., mains power restriction notification) transmission media. Through this embodiment, it can be ensured that the mains power restriction notification process will not be interfered with by other factors, and it is only related to whether the mains power restriction notification is transmitted. In the case of normal mains power supply, the mains power restriction notification cannot or does not need to be transmitted; in the case of abnormal mains power supply, the mains power restriction notification can be transmitted. Therefore, based on whether the signal receiving module receives the mains power restriction notification, it can be accurately judged whether the mains power supply is normal, so that the operation mode of the air conditioner can be automatically controlled to meet the actual situation of the mains power supply.

[0051] In another embodiment, when the signal transmitting module is normally powered, the signal transmitting module and the signal receiving module may also transmit the utility power curtailment notification via wireless signal transmission, including but not limited to Wifi, NB-IOT, LoRa, and ZigBee. The signal transmitting module transmits the utility power curtailment notification, and the signal receiving module receives the utility power curtailment notification, with wireless signal transmission between the two. This can achieve multi-node control, wide coverage, low power consumption, and minimal impact from grid operation fluctuations. This prevents the utility power curtailment notification from being affected by voltage fluctuations and causing signal transmission distortion, and can achieve transmission of the utility power curtailment notification independently of the grid operation status.

[0052] FIG3 is a flow chart of determining that the signal receiving module has not received the mains power restriction notification provided by the present application.

[0053] The process of determining that the signal receiving module has not received the mains power restriction notification will be described below with reference to FIG. 3 .

[0054] In an exemplary embodiment of the present application, as can be seen from FIG. 3 , determining that the signal receiving module has not received the mains power restriction notification may include steps 310 to 350 , each of which will be described below.

[0055] In step 310, a preset frequency band signal in the mains power grid is collected based on the signal sending module.

[0056] In step 320, the preset frequency band signal is modulated to obtain a modulated signal.

[0057] In step 330 , the modulated signal is loaded onto the power line for transmission. When the commercial power grid is normally powered, the power line has the ability to transmit signals.

[0058] In step 340 , when the signal receiving module receives the modulated signal based on the power line, the signal receiving module demodulates the modulated signal to obtain a demodulated signal.

[0059] In step 350 , when it is detected that the demodulated signal includes a signal of a preset frequency band, it is determined that the signal receiving module has not received a notice of a mains power restriction.

[0060] In one embodiment, high-voltage power lines, medium-voltage power lines, or low-voltage distribution lines are used as information transmission media instead of WiFi or infrared transmission. A preset frequency band signal in the mains power grid can be collected based on the signal sending module, and the preset frequency band signal can be modulated to obtain a modulated signal. The modulated signal is then loaded onto the power line for transmission. It should be noted that when the mains power grid is normally powered, the power line has the ability to transmit signals. In other words, when the mains power grid is normally powered, the signal receiving module can receive the signal sent by the signal sending module.

[0061] Furthermore, at the signal receiving module end, when the signal receiving module receives a modulated signal based on the power line, the modulated signal can be demodulated again based on the signal receiving module to obtain a demodulated signal, and it can be determined whether the demodulated signal includes a preset frequency band signal. If the demodulated signal includes a preset frequency band signal, it means that the mains power grid can supply power normally, that is, the signal receiving module has not received the mains power restriction notification. Through this embodiment, it can be ensured that based on the mains power restriction notification received by the signal receiving module, it can accurately determine whether the mains power grid can supply power normally, thereby laying the foundation for automatically controlling the operation of the air conditioner.

[0062] FIG4 is a flow chart of determining that a signal receiving module receives a notice of utility power restriction, as provided in the present application.

[0063] In order to further understand the air conditioner operation mode control method provided by this application, it will be explained below with reference to FIG. 4 .

[0064] In an exemplary embodiment of the present application, in combination with Figure 4, it can be seen that the air conditioner operation mode control method may include steps 410 to 440, wherein steps 410 to 430 are the same or similar to steps 310 to 330. Please refer to the previous description for its specific implementation and beneficial effects. They will not be repeated in this embodiment. Step 440 will be introduced below.

[0065] In step 440 , the signal receiving module determines that it has received a notice of a utility power cut-off based on the fact that the power line has not received the modulated signal within the preset time period.

[0066] It should be noted that, when the mains power grid is supplying power normally, the power line has the ability to transmit signals. In other words, when the mains power grid is supplying power normally, the signal receiving module can receive the signal sent by the signal sending module. When the mains power grid is not supplying power normally, the power line does not have the ability to transmit signals. In other words, when the mains power grid is not supplying power normally, the signal receiving module cannot receive the signal sent by the signal sending module. Therefore, in one example, if the signal receiving module does not receive the modulated signal based on the power line within a preset time period, it indicates that the mains power grid is not supplying power normally. In other words, it is determined that the signal receiving module has received a mains power restriction notification.

[0067] Furthermore, if the signal receiving module receives a notice of a utility power curtailment, it controls the signal receiving module to transmit an energy-saving instruction to the indoor unit via the signal transmission channel, so that upon receiving the energy-saving instruction, the indoor unit automatically adjusts the air conditioner to operate in energy-saving mode. This embodiment automatically adjusts the air conditioner to operate in energy-saving mode even when the utility power grid fails or a notice of a utility power curtailment is received, without incurring any additional costs. This ensures that other electrical appliances and the air conditioner can operate effectively, thereby improving the user experience and satisfaction during use.

[0068] FIG5 is a schematic diagram of the application scenario structure of the air conditioner operation mode control method provided in this application.

[0069] In order to further introduce the air conditioner operation mode control method provided in this application, it will be explained below with reference to FIG5 .

[0070] In an exemplary embodiment of the present application, in conjunction with Figure 5, it can be seen that for areas with a shortage of power supply, each family can be equipped with an electric control adapter box (corresponding to the power conversion device in Figure 5) placed outdoors, and the electric control adapter box can be divided into an input end and an output end. In conjunction with Figure 5, it can be seen that the input end is composed of personal power generation, community power generation and mains power. The output end can be connected to a standby power supply 1 to a standby power supply N. During application, the input end power supply can come from respective power sources, such as mains power, community power generation, personal generator, etc., and the output end power supply is connected to a household standby power socket. In addition, mains power is directly connected to a household mains socket for non-essential continuous electrical appliances. Among them, the outdoor unit of the present application can be powered by a standby power supply N.

[0071] It should be noted that in Figure 5, N represents the neutral wire, and L represents the live wire. S represents the inherent signal transmission channel between the indoor and outdoor units. The outdoor unit and the receiving module (corresponding to the signal receiving module of this application) can be connected via a power line to ensure information transmission between the two.

[0072] In one example, the installation form of the transmitting module (corresponding to the signal transmitting module in this application) can be a three-prong plug. The transmitting module can be powered by the mains. The receiving module is installed next to the outdoor unit or built into it, and its power supply comes from the outdoor unit power supply. The receiving module can be installed at one end of the signal transmission channel S of the outdoor unit, so that the indoor computer board can be notified of the presence of mains power by means of the inherent signal transmission channel S. After receiving the signal, the indoor unit determines whether there is mains power, and then sends a command to the outdoor unit to determine whether energy-saving control is performed. In another example, there is a signal line connection between the receiving module and the outdoor unit for communication.

[0073] The power supply of the air conditioner can come from the indoor permanent power socket to ensure its continuous operation. The transmitting module is plugged into the indoor AC socket, and the receiving module is installed on or next to the outdoor unit. The number of receiving modules is not limited to 1. It depends on the number of air conditioners installed in the home. The number of receiving modules can be equivalent to the number of outdoor units. There can be only one transmitting module or multiple transmitting modules.

[0074] During application, when the mains power supply is normal, the transmitting module is powered by power and can transmit signals to the receiving module normally. The power line carrier communication is normal. The receiving module only performs signal analysis and does not issue energy-saving commands. The air conditioner can operate according to the user settings.

[0075] When the mains power is lost and other power sources are used to power the home, the mains power outlet becomes de-energized, and the transmitter module is unable to transmit signals to the receiver module. The receiver module is then programmed to send a command to the air conditioner's internal computer to put the air conditioner into energy-saving mode, controlling its energy-saving operation and ensuring that other electrical appliances can operate within its limited power capacity. This allows the air conditioner to be automatically controlled to meet the actual power supply situation, while ensuring the normal operation of other electrical appliances, thereby improving the user experience and satisfaction during use.

[0076] As can be seen from the above description, the air conditioner operation mode control method provided in this application controls the signal receiving module to send an energy-saving instruction to the indoor unit of the air conditioner based on the inherent signal transmission channel between the outdoor and indoor units when the signal receiving module receives a notice of a utility power limit. Furthermore, when the indoor unit receives the energy-saving instruction, the air conditioner is automatically adjusted to operate in energy-saving mode. In this application, the signal receiving module reuses the signal transmission channel to send the energy-saving instruction to the indoor unit of the air conditioner, and controls the air conditioner to operate in energy-saving mode based on the energy-saving instruction. This achieves automatic control of the air conditioner's operation at a low cost, improving the user experience and satisfaction during use.

[0077] Based on the same concept, the present application also provides an air conditioner operation mode control device.

[0078] The air conditioner operation mode control device provided in the present application is described below. The air conditioner operation mode control device described below and the air conditioner operation mode control method described above can refer to each other.

[0079] FIG6 is a schematic structural diagram of the air conditioner operation mode control device provided in the present application.

[0080] In an exemplary embodiment of the present application, as can be seen from FIG. 6 , the air conditioner operation mode control device may include a control module 610 and an adjustment module 620 , each of which will be described below.

[0081] The control module 610 may be configured to, when the signal receiving module receives a notice of utility power curtailment, control the signal receiving module to send an energy-saving instruction to the indoor unit based on a signal transmission channel inherent between the outdoor unit and the indoor unit of the air conditioner, wherein the signal receiving module is powered by the outdoor unit, and the utility power curtailment notice is sent by the signal sending module, which is powered by the utility power;

[0082] The adjustment module 620 may be configured to automatically adjust the air conditioner to operate in an energy-saving mode when the indoor unit receives an energy-saving instruction.

[0083] In an exemplary embodiment of the present application, the control module 610 may also be configured to:

[0084] In the case that the signal receiving module does not receive the mains power restriction notification, the control signal receiving module sends the instruction to operate according to the current operation mode to the indoor unit based on the signal transmission channel;

[0085] The adjustment module 620 may also be configured to:

[0086] When the indoor unit receives an instruction to operate in accordance with the current operation mode, the air conditioner is controlled to continue operating in accordance with the current operation mode.

[0087] In an exemplary embodiment of the present application, the signal receiving module and the signal sending module may transmit the mains power restriction notification in a power line carrier communication manner.

[0088] In an exemplary embodiment of the present application, the control module 610 may determine that the signal receiving module has not received the mains power restriction notification in the following manner:

[0089] Based on the signal sending module, a preset frequency band signal in the mains power grid is collected;

[0090] Modulating a preset frequency band signal to obtain a modulated signal;

[0091] Loading the modulated signal onto the power line for transmission, wherein the power line has the ability to transmit signals when the mains power grid is operating normally;

[0092] When the signal receiving module receives the modulated signal based on the power line, the signal receiving module demodulates the modulated signal to obtain a demodulated signal;

[0093] In the case where it is detected that the demodulated signal includes a preset frequency band signal, it is determined that the signal receiving module has not received the mains power restriction notification.

[0094] In an exemplary embodiment of the present application, the control module 610 may also be configured to:

[0095] In a preset time period, the signal receiving module determines that the signal receiving module has received a city power restriction notification based on the fact that the power line has not received the modulated signal.

[0096] In an exemplary embodiment of the present application, when there are multiple air conditioners, a signal receiving module is configured for the outdoor unit of each air conditioner to send energy-saving instructions and / or instructions to operate according to the current operating mode to the corresponding outdoor unit based on the signal receiving module.

[0097] FIG7 illustrates a schematic diagram of the physical structure of an electronic device. As shown in FIG7 , the electronic device may include: a processor 710, a communication interface 720, a memory 730, and a communication bus 740. The processor 710, the communication interface 720, and the memory 730 communicate with each other via the communication bus 740. The processor 710 may invoke logic instructions in the memory 730 to execute a method for controlling an air conditioner operating mode. The method includes: upon receiving a notice of a mains power restriction, controlling the signal receiving module to send an energy-saving instruction to the indoor unit of the air conditioner based on a signal transmission channel inherent between the outdoor and indoor units of the air conditioner, wherein the signal receiving module is powered by the outdoor unit, and the mains power restriction notice is sent by a signal sending module, which is powered by the mains; and upon receiving the energy-saving instruction, the indoor unit automatically adjusts the air conditioner to operate in an energy-saving mode.

[0098] In addition, the logic instructions in the above-mentioned memory 730 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when sold or used as an independent product. Based on this understanding, the technical solution of the present application is essentially or the part that contributes to the prior art or the part of the technical solution can be embodied in the form of a software product, and the computer software product is stored in a storage medium, including a number of instructions for enabling a computer device (which can be a personal computer, a server, or a network device, etc.) to execute all or part of the steps of the method described in each embodiment of the present application. The aforementioned storage medium includes: various media that can store program codes, such as a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk.
