Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for energy saving in air conditioners, an air conditioner, and a storage medium. Background Technology

[0002] Currently, some underdeveloped areas suffer from power shortages. Besides municipal power, they rely on town generators, community generators, and personal generators, but these are costly to operate. Therefore, air conditioners with ECO energy-saving functions are very popular in these areas. Currently, air conditioners require manual operation of the remote control to enter ECO mode, which is inconvenient at night or when children / elders are home alone, leading to increased electricity costs. Therefore, how to enable air conditioners to automatically enter ECO mode has become a pressing issue.

[0003] The related technology discloses an air conditioner energy-saving control method, including: receiving a power grid signal indicating a power shortage; and controlling the air conditioner to operate in energy-saving mode based on the power grid signal indicating a power shortage. This solves the problem that air conditioners often cannot operate stably when the external power grid supply situation changes, thus enabling the air conditioner to flexibly adjust its operating strategy when the external power grid supply situation changes.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Air conditioners use different power supply methods, each with varying power consumption. Therefore, energy-saving modes corresponding to different power supply methods are used for energy management. In practical applications, a communication response mechanism can be used to detect different power supply methods and activate the corresponding energy-saving mode. However, the air conditioner's receiving module may be interfered with by signals from other air conditioner's transmitting modules, leading to misjudgment of the power supply method and accidental activation of the energy-saving mode, thus affecting the user experience.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method and apparatus for energy saving in air conditioners, an air conditioner, and a storage medium to avoid signal interference from the receiving module of an air conditioner to the transmitting module of other air conditioners, which could lead to misjudgment of the power supply mode and accidental activation of the power saving mode, thereby improving the user experience.

[0009] In some embodiments, the air conditioner includes a transmitting module and a receiving module; the method includes: when the transmitting module is powered on, increasing the frequency of transmitting a first signal within a set time period; controlling the receiving module to determine the sequence number of the first signal with the highest received frequency as a target sequence number; and controlling the receiving module to receive the first signal containing the target sequence number.

[0010] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to execute the above-described method for energy saving in an air conditioner when executing the program instructions.

[0011] In some embodiments, the air conditioner includes:

[0012] The air conditioner body includes a transmitting module, a receiving module, and a display module; and...

[0013] The aforementioned energy-saving device for air conditioners is installed on the air conditioner itself.

[0014] In some embodiments, the storage medium stores program instructions that, when executed, perform the above-described method for energy saving in an air conditioner.

[0015] The method, apparatus, air conditioner, and storage medium for energy saving in air conditioners provided in this disclosure can achieve the following technical effects:

[0016] When the transmitting module powers on, the frequency of sending the first signal within a set time period is increased, and the receiving module is controlled to determine the sequence number of the first signal with the highest received frequency as the target sequence number. Finally, the receiving module is controlled to receive the first signal containing the target sequence number. By increasing the frequency of signals sent by the current air conditioner's transmitting module, signals sent by the current air conditioner's transmitting module can be filtered out. Therefore, controlling the receiving module to receive signals with the target sequence number ensures that the receiving module only receives signals sent by the current air conditioner's transmitting module. This avoids interference from signals from other air conditioner's transmitting modules, preventing misjudgment of the power supply mode and accidental activation of power-saving modes, thus improving the user experience.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0029] Unless otherwise stated, the term "multiple" means two or more.

[0031] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0032] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0033] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0034] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances via the internet, or directly via Bluetooth, Wi-Fi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0035] This disclosure provides an air conditioner, including an infrared module, a buzzer, a transmitting module, and a receiving module. The transmitting module sends a signal containing a serial number to the receiving module. The serial number includes a first serial number for matching and a special serial number. The special serial number can be any set serial number, such as a fire serial number or a flood serial number. The buzzer is used to warn the user. The infrared module receives and sends control commands to a control board to control the air conditioner in case the receiving module is damaged or malfunctions.

[0036] After successfully matching with the transmitting module, the receiving module only receives signals containing the first sequence number of the corresponding transmitting module, as well as signals containing special sequence numbers. Specifically, the transmitting module can send signals to the receiving module via power line carrier communication. For example, when the transmitting module sends a signal, it uses modulation technology to modulate the data, loading the high-frequency signal carrying the information onto the current, and then transmitting it on the power line. At the receiving end (receiving module), the modulated signal is first extracted by a filter, then demodulated to obtain the original communication signal, which is then transmitted to the air conditioner control board to realize information transmission and thus achieve intelligent control of the air conditioner.

[0037] Based on the structure of the air conditioner described above, such as Figure 1 As shown, this disclosure provides a method for energy saving in air conditioners, including:

[0038] S01, the air conditioner responds to the power-saving control command and detects the current power supply mode of the air conditioner.

[0039] S02, the air conditioner determines the target power-saving mode based on the current power supply method of the air conditioner.

[0040] S03, the air conditioner operates according to the target energy-saving mode.

[0041] The power supply method includes any power supply method, such as urban power generation, community power generation, personal power generation, municipal power generation, etc.

[0042] The energy-saving method for air conditioners provided in this disclosure responds to a power-saving control command, detects the current power supply mode of the air conditioner, determines a target power-saving mode based on the current power supply mode, and finally controls the air conditioner to operate according to the target power-saving mode. By executing the power-saving mode corresponding to the current power supply mode, the energy-saving control of the air conditioner can be matched with the current power supply mode, thereby meeting the energy-saving needs under different power supply modes and improving the energy-saving effect of the air conditioner's energy-saving control.

[0043] Optionally, the air conditioner determines the target power-saving mode based on its current power supply method, including: the air conditioner obtaining the electricity cost of different power supply methods; and the air conditioner determining the target power-saving mode based on the current power supply method and electricity cost.

[0044] In this way, the air conditioner obtains the electricity costs of different power supply methods and determines the target energy-saving mode based on the current power supply method and electricity costs. Determining the target energy-saving mode based on electricity costs allows the target energy-saving mode to match the electricity costs, thereby saving electricity more accurately and reducing electricity costs.

[0045] Optionally, the air conditioner determines the target energy-saving mode based on the current power supply method and electricity cost, including: the air conditioner sorts different power supply methods according to electricity cost to determine the cost ranking of the current power supply method; the air conditioner determines the target energy-saving mode corresponding to the cost ranking based on a preset first relationship.

[0046] Among them, the electricity cost of the current power supply method is negatively correlated with the total power of the target power-saving mode.

[0047] In this way, the air conditioner sorts different power supply methods according to electricity cost, determines the cost ranking of the current power supply method, and determines the target energy-saving mode corresponding to the cost ranking based on a preset first relationship. The cost ranking reflects the electricity cost of the current power supply method compared to all other power supply methods, thus allowing the determination of the most suitable target energy-saving mode from among different energy-saving modes, achieving precise energy saving. Furthermore, the higher the electricity cost of an energy-saving mode, the lower the power of the target energy-saving mode, thereby controlling the electricity cost within a set cost range and avoiding excessively high electricity costs that lead to a poor user experience. For example, if the total operating power of the air conditioner is 3000W, and the cost ranking is: Urban Power Generation > Community Power Generation > Personal Power Generation > Municipal Power Generation, then the corresponding relationships are: Urban Power Generation: Energy-Saving Mode L1; Community Power Generation: Energy-Saving Mode L2; Personal Power Generation: Energy-Saving Mode L3; Municipal Power Generation: Energy-Saving Mode L4; where L1 is 800W, L2 is 1500W, L3 is 2000W, and L4 is 2500W.

[0048] Optionally, after controlling the air conditioner to operate according to the target power-saving mode, the method further includes: the air conditioner detecting the current voltage of the power supply to the air conditioner; and the air conditioner adjusting the operating frequency of the compressor according to the current voltage.

[0049] In this way, the air conditioner detects the current voltage of its power supply and adjusts the compressor's operating frequency accordingly. When the power supply environment changes—whether it's urban power generation, community power generation, personal power generation, or municipal power generation—i.e., when the voltage becomes unstable, it may affect the normal operation of the air conditioner. Therefore, the air conditioner dynamically adjusts the compressor's operating frequency based on the current voltage, thereby achieving the goal of dynamic energy-saving management and ensuring the stable operation of the air conditioner.

[0050] Optionally, the air conditioner detects its current power supply mode, including: the air conditioner responds to a power-saving control command, determines a set period based on the current power supply mode, and the air conditioner detects the current voltage at set intervals.

[0051] In this way, the air conditioner responds to energy-saving control commands, determines a set cycle based on the current power supply method, and checks the current voltage at set intervals. Since different power supply methods differ, their instability standards also differ. Therefore, the air conditioner determines the corresponding set cycle based on different power supply methods to more accurately detect the stability of the power environment under different power supply methods.

[0052] Optionally, the air conditioner adjusts the compressor's operating frequency according to the current voltage, including: the air conditioner obtaining the standard voltage of the current power supply method; the air conditioner calculating the voltage ratio between the current voltage and the standard voltage; and the air conditioner adjusting the compressor's operating frequency according to the voltage ratio.

[0053] In this way, the air conditioner obtains the standard voltage of the current power supply, calculates the voltage ratio between the current voltage and the standard voltage, and finally adjusts the compressor's operating frequency based on the voltage ratio. By proportionally reducing or increasing the current voltage based on the ratio, the air conditioner achieves stable operation, avoiding situations where unstable power conditions reduce its effectiveness in regulating the environment.

[0054] Optionally, the air conditioner adjusts the compressor's operating frequency based on the voltage ratio, including: the air conditioner calculating the product of the voltage ratio and the standard operating frequency, and determining the product as the target operating frequency; the air conditioner controlling the compressor to operate according to the target operating frequency.

[0055] In this way, the air conditioner calculates the product of the voltage ratio and the standard operating frequency, determines the target operating frequency, and finally controls the compressor to operate according to the target operating frequency. By determining the target operating frequency as the product of the voltage ratio and the standard operating frequency, the current voltage can be proportionally reduced or increased, thereby achieving stable operation of the air conditioner.

[0056] Optionally, the air conditioner controls the compressor to operate according to the target operating frequency, including: the air conditioner adjusts the compressor's operating frequency to the target operating frequency based on the voltage change rate of the power supply voltage.

[0057] The air conditioner adjusts the compressor's operating frequency to a target operating frequency based on the voltage change rate of the power supply voltage, including: the air conditioner acquiring a standard voltage change rate; when the current voltage change rate is less than the standard voltage change rate, the air conditioner adjusts the compressor's operating frequency to the target operating frequency at a first rate; when the current voltage change rate is greater than the standard voltage change rate, the air conditioner adjusts the compressor's operating frequency to the target operating frequency at a second rate.

[0058] The second rate is less than the first rate. When the standard voltage change rate is |K|, the frequency change value (the difference between the target operating frequency and the current operating frequency) is Y Hz; then the first rate n = Y / (|K1| / |K|); the second rate m = Y / (|K2| / |K|). K1 is the current voltage change rate when it is less than |K|, and K2 is the current voltage change rate when it is greater than |K|.

[0059] In this way, the air conditioner adjusts the compressor's operating frequency based on the rate of change of the supply voltage. This avoids excessively rapid and large fluctuations in the compressor's operating frequency, which can lead to instability and noise, thus improving the user experience. For example, if the supply voltage is detected to be 190V at the first time point, and then 200V is detected after a set interval, the standard voltage change rate is 10. The operating frequency needs to be adjusted from 46Hz (current) to 55Hz (target), a frequency change of 9Hz. If the current voltage change rate is below 10% (e.g., 6V), the first rate is 15Hz. In this case, the compressor's operating frequency reaches the target frequency without causing noise due to rapid frequency parameter changes, while also achieving energy savings.

[0060] Based on the structure of the air conditioner described above, such as Figure 2 As shown, this disclosure provides a method for energy saving in an air conditioner. Before detecting the current power supply mode of the air conditioner in response to a power-saving control command, the method further includes:

[0061] S21, the air conditioner determines the transmission cycle based on the current power supply method of the air conditioner.

[0062] S22, when the power supply voltage is stable, the air conditioner controls the transmitting module to send the first signal to the receiving module according to the transmitting cycle.

[0063] S23, if the number of times the receiving module fails to receive the first signal exceeds the set number, the air conditioner will start the power saving mode.

[0064] Specifically, activating the power-saving mode of the air conditioner involves the receiving module sending a power-saving control command to the control board, thereby prompting the air conditioner to respond to the command and execute power-saving operations. The specific steps for executing the power-saving operation can be those described in the preceding embodiments, and are not limited here. For example, the air conditioner determines the target power-saving mode based on the current power supply method; the air conditioner then controls its operation according to the target power-saving mode.

[0065] The energy-saving method for air conditioners provided in this disclosure determines the transmission cycle based on the current power supply mode of the air conditioner. When the power supply voltage is stable, the control transmission module sends a first signal to the receiving module according to the transmission cycle. If the receiving module fails to receive the first signal more than a set number of times, a power-saving mode is activated. Based on different power supply modes, a communication response mechanism corresponding to the current power supply mode is used to activate the power-saving mode, ensuring that the activation timing of the power-saving mode matches the current power supply mode. When using power-saving modes corresponding to different power supply modes for energy-saving control, the power-saving mode can be activated promptly under different power supply modes, improving the energy-saving effect of the air conditioner's energy-saving control. Furthermore, setting different transmission cycles according to different power supply modes allows the air conditioner to promptly determine the current power supply mode, thereby activating the power-saving mode corresponding to the current power supply mode, improving the accuracy of the air conditioner's energy-saving control and enhancing the energy-saving effect.

[0066] Optionally, the air conditioner determines the transmission cycle based on its current power supply method, including: the air conditioner determines the transmission cycle corresponding to the current power supply method based on a preset second relationship.

[0067] In this way, the air conditioner determines the transmission cycle corresponding to the current power supply mode based on the preset second relationship, thereby enabling the transmission module to match the period of sending the first signal with the current power supply mode. Since different power supply modes differ, detecting the power supply environment through the corresponding transmission cycle to determine whether to activate the power saving mode allows for more precise timing of the air conditioner's energy-saving control activation.

[0068] Optionally, after determining the transmission cycle based on the current power supply method of the air conditioner, the method further includes: the air conditioner detecting the power supply voltage and obtaining a standard voltage; the air conditioner determining that the power supply voltage is stable when the voltage difference between the power supply voltage and the standard voltage is less than a set error threshold; and the air conditioner determining that the power supply voltage is unstable when the voltage difference is greater than or equal to the set error threshold.

[0069] In this way, the air conditioner detects the supply voltage and obtains a standard voltage. If the voltage difference between the supply voltage and the standard voltage is less than a set error threshold, the difference is small, indicating low supply voltage fluctuation, and therefore the supply voltage is determined to be stable. If the voltage difference is greater than or equal to the set error threshold, the difference is small, indicating high supply voltage fluctuation, and therefore the supply voltage is determined to be unstable.

[0070] Optionally, the air conditioner obtains a standard voltage, including: the air conditioner determines the standard voltage corresponding to the power supply method according to a preset third relationship.

[0071] Thus, due to differences in power supply methods, such as varying stability, the standard voltage corresponding to each power supply method will also differ. Therefore, the air conditioner determines the standard voltage corresponding to the power supply method based on a preset third relationship, ensuring that the standard voltage is compatible with each power supply method and improving the accuracy of the air conditioner's energy-saving start-up timing.

[0072] Optionally, the air conditioner determines the number of times it can be set as follows: the air conditioner determines the number of times it can be set according to the current power supply method.

[0073] In this way, the air conditioner determines the number of times to be set according to the current power supply method, which can match the number of times to be set with the current power supply method, thereby increasing the accuracy of the timing of energy-saving control.

[0074] Optionally, the method for saving energy in an air conditioner further includes: when the air conditioner's transmitting module is powered on, the control display module displays a first color; when the air conditioner is in power-saving mode, the control display module displays a second color.

[0075] The first color can be any color, such as green, white, or blue. The second color can be any color different from the first color, such as red, yellow, or purple.

[0076] In this way, when the air conditioner's power-on module is powered on, the control display module displays the first color; when the power-saving mode is activated, the control display module displays the second color. By displaying different colors, users can clearly understand when the air conditioner's power-saving mode is activated, thus making the intelligent control process of the air conditioner clear and enhancing the user experience.

[0077] Based on the structure of the air conditioner described above, such as Figure 3 As shown, this disclosure provides a method for energy saving in an air conditioner, wherein an air conditioner control receiving module and a transmitting module are matched, including:

[0078] S31, when the air conditioner is powered on, the frequency of sending the first signal within the set duration of the sending module is increased.

[0079] S32, the air conditioner control receiving module determines the sequence number of the first signal with the highest frequency received as the target sequence number.

[0080] S33, the air conditioner control receiving module receives the first signal containing the target serial number.

[0081] When the air conditioner activates its power-saving mode, before the receiving module sends power-saving control commands to the control board—for example, during air conditioner installation, when the sending module is installed, or when the sending module is being repaired—the air conditioner needs to match the receiving module with the sending module. The sending module transmits detected information such as power supply method and voltage to the receiving module via the power line. The receiving module then sends this information to the control board to control the air conditioner's operation.

[0082] The energy-saving method for air conditioners provided in this disclosure increases the frequency of a first signal transmitted within a set time period when the transmitting module is powered on. The receiving module is then controlled to determine the sequence number of the highest-frequency first signal received as the target sequence number. Finally, the receiving module receives the first signal containing the target sequence number. By increasing the frequency of signals transmitted by the current air conditioner's transmitting module, signals transmitted by the current air conditioner's transmitting module can be filtered out. Therefore, controlling the receiving module to receive signals with the target sequence number ensures that the receiving module only receives signals transmitted by the current air conditioner's transmitting module. This avoids interference from signals from other air conditioner's transmitting modules, preventing misjudgments of the power supply mode and accidental activation of energy-saving modes, thus improving the user experience.

[0083] Optionally, the air conditioner increases the frequency of the first signal being sent by the sending module within a set time period, including: the air conditioner shortens the sending period of the first signal being sent by the sending module according to a set ratio; the air conditioner controls the sending module to send the first signal according to the shortened sending period.

[0084] In this way, the air conditioner shortens the transmission period of the first signal sent by the transmitting module according to a set ratio, and controls the transmitting module to send the first signal according to the shortened transmission period. By shortening the transmission period, the frequency of sending the first signal is increased within a set time, thereby enabling the receiving module to select the transmitting module in the current air conditioner from among many signals for matching, avoiding interference from the first signals sent by other air conditioner transmitting modules.

[0085] Optionally, the air conditioner control receiving module determines the sequence number of the first signal with the highest frequency received as the target sequence number, including: the air conditioner acquiring the number of times the first signal corresponding to each sequence number of the receiving module is received; and the air conditioner determining the sequence number of the first signal with the most received times as the target sequence number.

[0086] In this way, the air conditioner obtains the number of times the first signal corresponding to each serial number of the receiving module is received, and determines the serial number of the first signal with the most receptions as the target serial number. Within a set time period, the more times the receiving module receives the first signal, the more likely it is that the transmitting module that issued the first signal is the transmitting module of the current air conditioner. Therefore, the serial number in the first signal is used as the target serial number for matching.

[0087] Optionally, the air conditioner control receiving module receives a first signal containing a target serial number, including: the air conditioner determining whether the serial number of the first signal is the same as the target serial number; if they are the same, the air conditioner receives the first signal.

[0088] In this way, the air conditioner determines whether the sequence number of the first signal is the same as the target sequence number, and if they are the same, it receives the first signal. After determining the target sequence number, by filtering out the first signals with the same sequence number as the target sequence number, it is possible to filter out the signals emitted by the current air conditioner transmitting module, thus avoiding signal interference from other transmitting modules.

[0089] Based on the structure of the air conditioner described above, such as Figure 4 As shown, this disclosure provides a method for energy saving in air conditioners, including:

[0090] S41, the air conditioner responds to the intelligent start control command and determines the first temperature threshold based on user habits.

[0091] S42 is the absolute value of the temperature difference between the indoor ambient temperature and the user-set temperature, calculated by the air conditioner.

[0092] S43, the air conditioner activates the power-saving mode when the absolute value is less than the first temperature threshold.

[0093] Users can activate the smart start function by using the smart start button on the remote control or by voice control.

[0094] The energy-saving method for air conditioners provided in this disclosure responds to a smart start control command, determines a first temperature threshold based on user habits, and calculates the absolute value of the temperature difference between the indoor ambient temperature and the user-set temperature. If the absolute value is less than the first temperature threshold, a power-saving mode is activated. In addition to the air conditioner automatically entering energy-saving operation based on the power supply environment, a smart start mode for the power-saving mode is set. This mode determines the first temperature threshold based on user habits and controls the activation of the power-saving mode based on the first temperature threshold and the indoor temperature difference, fully considering the user's needs for indoor temperature. This makes the activation and deactivation of the power-saving mode more considerate of the user's temperature needs compared to automatically entering energy-saving operation based on the power supply environment, achieving a balance between user needs and energy saving, and improving the user experience.

[0095] Optionally, the air conditioner determines a first temperature threshold based on user habits, including: the air conditioner acquiring first temperature data when the user actively activates the power-saving mode within a set time period; the air conditioner determining a first average temperature difference between the indoor ambient temperature and the user-set temperature based on the first temperature data; and the air conditioner determining the first average temperature difference as the first temperature threshold.

[0096] The power-saving mode can be activated by the user pressing the power-saving mode button on the remote control, by the user activating the power-saving mode via voice, or by the user activating the power-saving mode via gesture control.

[0097] In this way, the air conditioner acquires the first temperature data when the user actively activates the power-saving mode within a set time period. Based on this first temperature data, it determines the first average temperature difference between the indoor ambient temperature and the user-set temperature, and finally sets this first average temperature difference as the first temperature threshold. Based on the indoor temperature data when the user actively activates the power-saving mode, it can determine how much of a temperature difference between the indoor ambient temperature and the user-set temperature will trigger the user's preference for energy saving and prompt them to actively activate the power-saving mode. This ensures that the first temperature threshold matches the user's needs, improving the accuracy of the power-saving mode activation timing in intelligent control.

[0098] Optionally, after responding to the intelligent start control command, the air conditioner further includes: determining a second temperature threshold based on user habits; and turning off the power-saving mode when the absolute value is greater than the second temperature threshold.

[0099] In this way, the air conditioner determines a second temperature threshold based on user habits, and shuts off the energy-saving mode when the absolute value exceeds the second temperature threshold. Determining a second temperature threshold that meets user needs based on user habits allows for more precise timing of the energy-saving mode shutdown.

[0100] Optionally, the air conditioner determines a second temperature threshold based on user habits, including: the air conditioner acquiring second temperature data when the user actively turns off the power-saving mode within a set time; the air conditioner determining a second average temperature difference between the indoor ambient temperature and the user-set temperature based on the second temperature data; and the air conditioner determining the second average temperature difference as the second temperature threshold.

[0101] In this way, the air conditioner acquires second temperature data when the user actively turns off the power-saving mode within a set time period. Based on this second temperature data, it determines the second average temperature difference between the indoor ambient temperature and the user-set temperature, and finally sets this second average temperature difference as the second temperature threshold. Based on the indoor temperature data when the user actively turns off the power-saving mode, it can determine how much of a temperature difference between the indoor ambient temperature and the user-set temperature will cause the user to favor their temperature needs (turn off the power-saving mode). This ensures that the first temperature threshold matches the user's needs, improving the accuracy of the power-saving mode activation timing in intelligent control.

[0102] Optionally, after responding to the intelligent start control command, the air conditioner may further include: when the absolute value is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, the air conditioner may determine whether to activate the power saving mode based on user feedback.

[0103] The method of determining whether to activate power saving mode based on user feedback can be any interactive method, such as sending a message to the client asking whether to activate power saving mode or asking the user via voice and providing feedback to the user to determine whether to activate power saving mode.

[0104] In this way, when the absolute value of the air conditioner is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, it is impossible to determine whether the user's needs are more focused on saving energy or adjusting the temperature. Therefore, the system determines whether to activate the energy-saving mode based on user feedback. By interacting with the user, the system can help the user better understand the intelligent control of the air conditioner and meet the user's needs for actively saving energy or changing the temperature.

[0105] Optionally, the air conditioner receives the smart start control command in the following manner: the air conditioner receives the smart start control command issued by the remote control through an infrared module.

[0106] In this way, the air conditioner receives the intelligent start control command from the remote control through the infrared module. Receiving the command through the infrared module can avoid the situation where the power-saving mode cannot be turned on when the receiver module is damaged, thus improving the user experience.

[0107] Optionally, the method for saving energy for the user's air conditioner also includes: activating the energy-saving mode when the air conditioner is not in energy-saving mode and the power consumption exceeds the user's set power consumption.

[0108] In this way, when the air conditioner is not in power-saving mode and the power consumption exceeds the user's set power consumption, it will activate the power-saving mode. By automatically detecting the power consumption and activating the power-saving mode in time when the power consumption is too high, the user can avoid frequently checking the power consumption due to concerns about excessive power consumption, thus improving the user experience.

[0109] Based on the structure of the air conditioner described above, such as Figure 5 As shown, this disclosure provides a method for energy saving in an air conditioner, which includes the following steps when no smart start control command is received:

[0110] S51, the air conditioner calculates the temperature difference between the indoor ambient temperature and the user-set temperature.

[0111] S52, when the temperature difference is less than the first temperature threshold, the air conditioner switches to the first power supply mode with the lowest cost.

[0112] S53, if the temperature difference is greater than the second temperature threshold, the air conditioner switches to the second power supply mode with the highest stability.

[0113] The energy-saving method for air conditioners provided in this disclosure calculates the temperature difference between the indoor ambient temperature and the user-set temperature. If the temperature difference is less than a first temperature threshold, the system switches to a first power supply mode with the lowest cost. If the temperature difference is greater than a second temperature threshold, the system switches to a second power supply mode with the highest stability. By switching power supply modes based on the indoor temperature difference and the electricity cost and stability of each mode, the system fully considers the user's temperature requirements, the stability of the power supply environment, and electricity costs. This addresses the problem of unstable air conditioner operation at its source, avoiding a situation where the air conditioner is constantly in energy-saving mode, which could reduce its environmental regulation effectiveness and thus improve the user experience.

[0114] Optionally, the air conditioner determines the first power supply mode in the following manner: the air conditioner sorts the power supply modes according to their cost based on the cost data of each power supply mode uploaded by the user, and obtains the first power supply mode.

[0115] In this way, the air conditioner sorts the power supply modes according to their cost based on the cost data uploaded by the user, and obtains the first power supply mode. Based on the electricity cost, the first power supply mode is determined, which not only meets the user's temperature needs, but also saves electricity costs and improves the user experience.

[0116] Optionally, the air conditioner determines the second power supply mode in the following manner: the air conditioner determines the voltage fluctuation of each power supply mode based on the voltage data within the set time period of each power supply mode; the air conditioner sorts the power supply modes according to the magnitude of the fluctuation to obtain the second power supply mode.

[0117] In this way, the air conditioner determines the voltage fluctuation of each power supply mode based on the voltage data within the set time period, and sorts the power supply modes according to the magnitude of the fluctuation to obtain the second power supply mode. Determining the second power supply mode based on the magnitude of the fluctuation ensures that the second power supply mode can prioritize meeting the needs of power supply environment stability, thereby guaranteeing the temperature regulation effect of the air conditioner.

[0118] Optionally, the method for energy saving in air conditioners further includes: the air conditioner comprehensively scoring each power supply mode based on the cost and voltage fluctuation of each power supply mode; when the temperature difference is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, the air conditioner switches to the third power supply mode with the highest comprehensive score; wherein, cost is negatively correlated with the score, and voltage fluctuation is negatively correlated with the score.

[0119] In this way, the air conditioner comprehensively scores each power supply mode based on its cost and voltage fluctuation. When the temperature difference is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, it switches to the third power supply mode with the highest comprehensive score. Since the temperature difference is between the first and second temperature thresholds, there is no urgent need for temperature control or energy saving. Therefore, the air conditioner switches to the third power supply mode with the highest comprehensive score to achieve a balance between energy saving and temperature regulation, thus saving energy while ensuring effective temperature control. For example, the air conditioner assigns scores to the power supply costs and voltage fluctuations of personal power generation, community power generation, town power generation, and municipal power generation, ranking them separately. The scores for the same items (power supply cost and voltage fluctuation) are then added together to obtain the comprehensive score for each power supply mode.

[0120] Optionally, the air conditioner performs a comprehensive score for each power supply mode based on the cost and voltage fluctuation of each power supply mode, including: assigning a first score to each power supply mode based on the cost of each power supply mode; assigning a second score to each power supply mode based on the voltage fluctuation of each power supply mode; and adding the first score and the second score of each power supply mode to obtain a comprehensive score for each power supply mode.

[0121] In this way, the air conditioner assigns a first score to each power supply mode based on its cost, and a second score based on its voltage fluctuation. Finally, the first and second scores are added together to obtain a comprehensive score for each power supply mode. By assigning first and second scores based on electricity cost and voltage fluctuation, a comprehensive score is obtained, which reflects the cost value and stability of the power supply mode. This allows the air conditioner to switch power supply modes more accurately, while also considering energy saving and temperature control.

[0122] Based on the structure of the air conditioner described above, such as Figure 6 As shown, this disclosure provides a method for energy saving in an air conditioner, which includes the following steps when no smart start control command is received:

[0123] S61, when the transmitting module is powered on, the air conditioner determines that the first sequence number transmitted by the transmitting module is the target sequence number, and controls the receiving module to only receive the first signal containing the target sequence number.

[0124] S62, In the event of a fire, the air conditioner control transmission module sends a warning signal containing a fire sequence number to the target receiving module.

[0125] S63, the air conditioner control receiving module receives a second signal containing the fire sequence number and activates the buzzer.

[0126] The target receiving module includes a receiving module and receiving modules for other air conditioners within the fire-affected area. The fire sequence number can also be replaced with other disaster sequence numbers such as a flood sequence number.

[0127] The energy-saving method for air conditioners provided in this disclosure determines the first sequence number sent by the sending module as the target sequence number when the sending module is powered on, and controls the receiving module to only receive the first signal containing the target sequence number. In the event of a fire, the sending module is controlled to send a warning signal containing a fire sequence number to the target receiving module, and the receiving module is controlled to receive a second signal containing the fire sequence number and activate the buzzer. By additionally setting a special fire sequence number and causing all receiving modules to respond to the warning signal containing the fire sequence number during a fire, the limitation that the receiving module can only receive signals from the corresponding sending module within the current air conditioner is overcome. This avoids the situation where the air conditioner's receiving module can only receive signals from the matched sending module during a fire, thereby achieving timely fire warning and protecting the lives and property of users.

[0128] Optionally, the air conditioner determines whether a fire has occurred in the following manner: if the indoor temperature is higher than the set temperature, the concentration of the set gas is higher than the set concentration, and the indoor light intensity is higher than the set light intensity, the air conditioner determines that a fire has occurred; wherein, the set gas includes carbon dioxide or carbon monoxide.

[0129] In this case, if the indoor temperature is higher than the set temperature, the concentration of the set gas is higher than the set concentration, and the indoor light intensity is higher than the set light intensity, the gas concentration produced by the fire will be significantly higher than the normal value, and the temperature and light intensity will be higher. Therefore, it can be determined that the air conditioner is on fire.

[0130] Optionally, the air conditioner control sending module sends a warning signal containing a fire sequence number to the target receiving module, including: the air conditioner determining the target address based on the fire hazard level; the air conditioner determining the receiving module at the target address as the target receiving module; and the air conditioner control sending module sending the warning signal to the target receiving module.

[0131] In this way, the air conditioner determines the target address based on the fire hazard level, identifies the receiving module at that address as the target receiving module, and finally controls the transmitting module to send a warning signal to the target receiving module. Sending warning signals to the target module based on the hazard level avoids sending warning signals over a wide area, which could cause confusion for users who are not threatened by the fire.

[0132] Optionally, the air conditioner determines the target address based on the fire hazard level, including: the air conditioner determining the hazard level; the air conditioner determining the target floor number corresponding to the hazard level based on a preset third relationship; and the air conditioner determining the target address based on the target floor number.

[0133] In this way, the air conditioner determines the hazard level and, based on a preset third relationship, determines the target floor number corresponding to that hazard level. Finally, based on the target floor number, it determines the target address. By determining the floor number corresponding to the hazard level and thus the target address, the range of fire warning signal notifications can be matched with the area (floor number) threatened by fire, thereby achieving precise fire warning. For example, if there are 30 floors in total, with address bits assigned as 001, 002, 003, 004, 005, 006, 007, 008, etc., and a fire occurs at address bit 00X, then users on floors 00X-3 to 00X+3 will be notified, ensuring that even if a fire occurs, it will not affect other floors. Furthermore, the scope of notification (sending early warning signals to the receiving module) can be increased or decreased according to the size of the fire. For example, the correspondence between fire hazard level and target floor can be: Level 1: 00X-3 to 00X+3; Level 2: 00X-5 to 00X+5; Level 3: 00X-7 to 00X+7; Level 4: 00X-9 to 00X+9, etc.

[0134] Optionally, the air conditioner determines the hazard level by: the air conditioner detecting the current indoor temperature; the air conditioner determining the temperature range within which the current temperature falls; and the air conditioner determining the hazard level based on the temperature range.

[0135] In this way, the air conditioner detects the current indoor temperature and determines the temperature range within which it falls. Finally, based on the temperature range, it determines the hazard level. Determining the hazard level based on the current temperature range allows for accurate early warning because the temperature range can characterize the current fire intensity.
