Therefore, air conditioners with ECO energy saving function are very popular in these areas. At present, the air conditioner needs to be manually operated to enter the ECO mode by remote controller, but it cannot be operated in time when sleeping at night or when children / elderly are alone at home, resulting in the increase of power consumption cost.

[0033] In the embodiments of the present disclosure, the smart home appliance refers to a home appliance product formed by introducing microprocessors, sensor technology, and network communication technology into home appliances, having the characteristics of intelligent control, intelligent sensing, and intelligent application. The operation process of the smart home appliance often depends on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, the smart home appliance can achieve remote control and management of the smart home appliance by connecting electronic devices.

[0034] In the embodiments of the present disclosure, the terminal device refers to an electronic device with wireless connection function. The terminal device can be connected to the smart home appliance as described above through the Internet, or can be directly connected to the smart home appliance as described above through Bluetooth, Wi-Fi, and the like. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device in a hovercar, or any combination thereof. The mobile device may, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device may, for example, include a smart watch, a smart bracelet, a pedometer, and the like.

[0035] The embodiments of the present disclosure disclose an air conditioner, comprising: an infrared module, a buzzer, a sending module and a receiving module. The sending module is used to send 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, for example, a fire serial number, a flood serial number, etc. The buzzer is used to warn the user. The infrared module is used to receive and send control instructions to the control panel to control the air conditioner in the case of damage or abnormality of the receiving module.

[0036] The receiving module only receives signals containing the first serial number of the corresponding sending module and signals containing the special serial number after successfully matching with the sending module. Specifically, the sending module can send signals to the receiving module through power line carrier communication. For example, when the sending module sends signals, the data is modulated by using modulation technology, the high frequency carrying information is loaded on the current, and then transmitted on the power line. At the receiving end (receiving module), the modulated signal is taken out through the filter, and then demodulated to obtain the original communication signal, which is transmitted to the air conditioner control panel to realize information transmission, thereby realizing intelligent control of the air conditioner.

[0037] Based on the structure of the air conditioner described above, as shown in Figure 1 The embodiment of the present disclosure provides a method for energy saving of an air conditioner, comprising the following steps:

[0038] S01, the air conditioner detects the current power supply mode of the air conditioner in response to the control instruction of power saving.

[0039] S02, the air conditioner determines the target power saving mode according to the current power supply mode of the air conditioner.

[0040] S03, the air conditioner controls the air conditioner to run according to the target power saving mode.

[0041] The power supply mode includes any power supply mode, for example, town power generation, community power generation, personal power generation, municipal power generation, etc.

[0042] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure detects the current power supply mode of the air conditioner in response to the control instruction of power saving, and determines the target power saving mode according to the current power supply mode of the air conditioner, and finally controls the air conditioner to run 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, so that the energy saving control of the air conditioner meets the demand for energy saving under different power supply modes, and the energy saving effect of the energy saving control of the air conditioner is improved.

[0043] Optionally, the air conditioner determines the target power saving mode according to the current power supply mode of the air conditioner, comprising: the air conditioner acquires the electricity cost of different power supply modes; the air conditioner determines the target power saving mode according to the current power supply mode and the electricity cost.

[0044] In this way, the air conditioner acquires the electricity cost of different power supply modes, and determines the target power saving mode according to the current power supply mode and the electricity cost. Based on the electricity cost to determine the target power saving mode, the target power saving mode can be matched with the electricity cost, so as to save electricity more accurately and save electricity cost.

[0045] Optionally, the air conditioner determines the target power saving mode according to the current power supply mode and the electricity cost, comprising: the air conditioner sorts different power supply modes according to the electricity cost to determine the cost ranking of the current power supply mode; the air conditioner determines the target power saving mode corresponding to the cost ranking according to a preset first relationship.

[0046] The electricity cost of the current power supply mode is negatively related to the total power of the target power saving mode.

[0047] In this way, the air conditioner ranks different power supply modes according to power consumption costs, determines a cost ranking of a current power supply mode, and determines a target power saving mode corresponding to the cost ranking according to a preset first relationship. Through the cost ranking, the power consumption cost of the current power supply mode in all power supply modes can be reflected, so that the target power saving mode most suitable for the current power supply mode can be determined from different power saving modes, and accurate energy saving is achieved. Moreover, the higher the power consumption cost of the power saving mode, the lower the power of the target power saving mode corresponding to the power saving mode, so that the power consumption cost can be controlled within a set cost range, and the use experience of the user is not poor due to high power consumption cost. For example, the total power of the air conditioner is 3000W, and the cost ranking is: town power generation > community power generation > personal power generation > municipal power generation, and the corresponding relationship is: town power generation: power saving mode L1; community power generation: power saving mode L2; personal power generation: power saving mode L3; municipal power generation: power saving mode L4; wherein, L1 gear is 800W, L2 gear is 1500W, L3 gear is 2000W, and L4 gear is 2500W.

[0048] Optionally, after the air conditioner is controlled to operate according to the target power saving mode, the method further includes: detecting, by the air conditioner, a current voltage of power supply of the air conditioner; and adjusting, by the air conditioner, a running frequency of the compressor according to the current voltage.

[0049] In this way, the air conditioner detects a current voltage of power supply of the air conditioner, and adjusts a running frequency of the compressor according to the current voltage. When the power supply environment of one of town power generation, community power generation, personal power generation, and municipal power generation changes, that is, when the voltage is unstable, the normal operation of the air conditioner can be affected, so the air conditioner dynamically adjusts the running frequency of the compressor according to the current voltage, so as to achieve the purpose of dynamic power saving management and ensure the stable operation of the air conditioner.

[0050] Optionally, the air conditioner detects a current power supply mode of the air conditioner, including: determining, by the air conditioner, a set period according to the current power supply mode in response to a power saving control instruction; and detecting, by the air conditioner, a current voltage at intervals of the set period.

[0051] In this way, the air conditioner determines a set period according to a current power supply mode in response to a power saving control instruction, and detects a current voltage at intervals of the set period. Since different power supply modes are different, the standards of instability are also different, so the air conditioner determines a corresponding interval set period based on different power supply modes to more accurately detect the stability of the power supply environment of different power supply modes.

[0052] Optionally, the air conditioner adjusts the running frequency of the compressor according to the current voltage, including: obtaining, by the air conditioner, a standard voltage of the current power supply mode; calculating, by the air conditioner, a voltage ratio of the current voltage and the standard voltage; and adjusting, by the air conditioner, the running frequency of the compressor according to the voltage ratio.

[0053] Thus, the air conditioner obtains the standard voltage of the current power supply mode, and calculates the voltage ratio of the current voltage and the standard voltage, and finally adjusts the running frequency of the compressor according to the voltage ratio. Based on the ratio of the current voltage and the standard voltage, the current voltage is proportionally reduced or increased, so as to realize the stable running of the air conditioner. The unstable power environment is avoided, so as to reduce the effect of the air conditioner on adjusting the environment.

[0054] Optionally, the air conditioner adjusts the running frequency of the compressor according to the voltage ratio, including: the air conditioner calculates the product of the voltage ratio and the standard running frequency, and determines the product as the target running frequency; and the air conditioner controls the compressor to run according to the target running frequency.

[0055] Thus, the air conditioner calculates the product of the voltage ratio and the standard running frequency, and determines the product as the target running frequency, and finally controls the compressor to run according to the target running frequency. By determining the product of the voltage ratio and the standard running frequency as the target running frequency, the current voltage can be proportionally reduced or increased, so as to realize the stable running of the air conditioner.

[0056] Optionally, the air conditioner controls the compressor to run according to the target running frequency, including: the air conditioner adjusts the running frequency of the compressor to the target running frequency according to the voltage change rate of the power supply voltage.

[0057] Optionally, the air conditioner adjusts the running frequency of the compressor to the target running frequency according to the voltage change rate of the power supply voltage, including: the air conditioner obtains the standard voltage change rate; the air conditioner adjusts the running frequency of the compressor to the target running frequency according to the first rate when the current voltage change rate is less than the standard voltage change rate; and the air conditioner adjusts the running frequency of the compressor to the target running frequency according to the second rate when the current voltage change rate is greater than the standard voltage change rate.

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

[0059] In this way, the air conditioner adjusts the operating frequency of the compressor according to the voltage variation rate of the power supply voltage, so that the operating frequency of the compressor is not adjusted too fast and changes too much, the operating frequency of the compressor is not unstable, noise is not generated, and the user experience is improved. For example, when the power supply voltage is detected as 190V at the first time node and the power supply voltage is detected as 200V after a set period, the standard voltage variation rate is 10, the operating frequency needs to be adjusted from 46Hz (current) to 55Hz (target), the frequency variation value is 9Hz, and the first rate is 15Hz if the current voltage variation rate is below 10 (for example, 6V). At this time, the operating frequency value of the compressor can reach the target operating frequency, and the noise caused by the rapid change of the frequency parameter of the compressor can be avoided, and the energy saving effect can be achieved.

[0060] Based on the structure of the air conditioner described above, as shown in Figure 2 The embodiment of the present disclosure provides a method for energy saving of an air conditioner, and the air conditioner detects the current power supply mode of the air conditioner in response to a power saving control instruction, and further comprises the following steps.

[0061] S21, the air conditioner determines a sending period according to the current power supply mode of the air conditioner.

[0062] S22, the air conditioner controls the sending module to send a first signal to the receiving module according to the sending period in the case that the power supply voltage is stable.

[0063] S23, the air conditioner starts a power saving mode in the case that the number of times that the receiving module does not receive the first signal is greater than a set number of times.

[0064] The air conditioner starts the power saving mode specifically by sending a power saving control instruction from the receiving module to the control panel, so that the air conditioner performs a power saving operation in response to the power saving control instruction. The air conditioner performing the power saving operation can specifically adopt the steps in the foregoing embodiments, which are not limited here. For example, the air conditioner determines a target power saving mode according to the current power supply mode; and the air conditioner controls the air conditioner to operate according to the target power saving mode.

[0065] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure determines a sending period according to the current power supply mode of the air conditioner. In the case of stable power supply voltage, the sending module sends the first signal to the receiving module according to the sending period, and starts the power saving mode in the case that the receiving module does not receive the first signal for more than a set number of times. Based on different power supply modes, the starting of the power saving mode is realized by using the communication response mechanism corresponding to the current power supply mode, so that the starting time of the power saving mode matches the current power supply mode. In the case of energy saving control by using the power saving mode corresponding to different power supply modes, the power saving mode can be started in time under different power supply modes, and the energy saving effect of the energy saving control of the air conditioner is improved. In addition, different sending periods are set according to different power supply modes, so that the air conditioner can determine the current power supply mode in time, and the power saving mode corresponding to the current power supply mode can be started, the accuracy of the power saving control of the air conditioner is improved, and the energy saving effect is enhanced.

[0066] Optionally, the air conditioner determines the sending period according to the current power supply mode of the air conditioner, including: the air conditioner determines the sending period corresponding to the current power supply mode according to a preset second relationship.

[0067] In this way, the air conditioner determines the sending period corresponding to the current power supply mode according to the preset second relationship, so that the period of sending the first signal by the sending module matches the current power supply mode. Since different power supply modes are different, the power supply environment is detected by using the corresponding sending period to determine whether to start the power saving mode, so that the starting time of the energy saving control of the air conditioner is more accurate.

[0068] Optionally, after the air conditioner determines the sending period according to the current power supply mode of the air conditioner, the air conditioner further includes: the air conditioner detects the power supply voltage and obtains a standard voltage; the air conditioner determines that the power supply voltage is stable in the case that the voltage difference between the power supply voltage and the standard voltage is less than a set error threshold; and the air conditioner determines that the power supply voltage is unstable in the case that the voltage difference is greater than or equal to the set error threshold.

[0069] In this way, the air conditioner detects the power supply voltage and obtains a standard voltage. In the case that the voltage difference between the power supply voltage and the standard voltage is less than a set error threshold, the power supply voltage and the standard voltage have a small difference at this time, which indicates that the power supply voltage fluctuation is low, and therefore the power supply voltage is determined to be stable. In the case that the voltage difference is greater than or equal to the set error threshold, the power supply voltage and the standard voltage have a small difference at this time, which indicates that the power supply voltage fluctuation is high, and therefore the power supply voltage is determined to be unstable.

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

[0071] Thus, due to the difference between different power supply modes, for example, the stability is different. Therefore, the standard voltage corresponding to the power supply mode is also different. Thus, the air conditioner determines the standard voltage corresponding to the power supply mode according to the preset third relationship, which can adapt the standard voltage to each power supply mode and improve the accuracy of the energy-saving operation starting time of the air conditioner.

[0072] Optionally, the air conditioner determines the set number of times in the following manner: the air conditioner determines the set number of times corresponding to the power supply mode according to the current power supply mode.

[0073] Thus, the air conditioner determines the set number of times corresponding to the power supply mode according to the current power supply mode, which can match the set number of times with the current power supply mode, thereby increasing the accuracy of the energy-saving control starting time.

[0074] Optionally, the method for energy saving of the air conditioner further comprises: the air conditioner controls the display module to display a first color in the case that the sending module is powered on; and the air conditioner controls the display module to display a second color in the case that the power saving mode is started.

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

[0076] Thus, the air conditioner controls the display module to display a first color in the case that the sending module is powered on, and controls the display module to display a second color in the case that the power saving mode is started. By displaying different colors, the user can clearly understand the starting time of the power saving mode of the air conditioner, thereby making the user clear about the process of the intelligent control of the air conditioner and enhancing the user experience.

[0077] Based on the structure of the air conditioner described above, as shown in Figure 3 The embodiment of the present disclosure provides a method for energy saving of an air conditioner, the air conditioner controls the receiving module and the sending module to match, comprising:

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

[0079] S32, the air conditioner controls the receiving module to determine the sequence number of the first signal with the highest receiving frequency as a target sequence number.

[0080] S33, the air conditioner controls the receiving module to receive the first signal containing the target sequence number.

[0081] The air conditioner needs to control the matching of the receiving module and the sending module before the receiving module sends the power saving control instruction to the control panel, for example, when the air conditioner is installed, when the sending module is installed, or when the sending module is maintained. The sending module is used to send the detected power supply mode, power supply voltage and other information to the receiving module through the power line, and the receiving module sends the above information to the control panel to control the operation of the air conditioner.

[0082] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure improves the frequency of sending the first signal within the set time period of the sending module when the sending module is powered on, controls the receiving module to determine the sequence number of the first signal with the highest frequency as the target sequence number, and finally controls the receiving module to receive the first signal containing the target sequence number. By improving the frequency of sending the signal by the sending module of the current air conditioner, the signal sent by the sending module of the current air conditioner can be screened out. Therefore, by controlling the receiving module to receive the signal with the target sequence number, the receiving module can only receive the signal sent by the sending module of the current air conditioner. This avoids the situation that the receiving module of the air conditioner is interfered by the signal of the sending module of other air conditioners, resulting in misjudgment of the power supply mode and misstart of the power saving mode, and improves the user experience.

[0083] Optionally, the air conditioner improves the frequency of sending the first signal within the set time period of the sending module, including: the air conditioner shortens the sending period of the sending module for sending the first signal by a set proportion; and 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 sending period of the sending module for sending the first signal by a set proportion, and controls the sending module to send the first signal according to the shortened sending period. By shortening the sending period, the frequency of sending the first signal is improved within the set time period, so that the receiving module can screen out the sending module in the current air conditioner from a large number of signals for matching, and avoid the interference of the first signal sent by the sending module of other air conditioners.

[0085] Optionally, the air conditioner controls the receiving module to determine the sequence number of the first signal with the highest frequency as the target sequence number, including: the air conditioner obtains the receiving times of the first signal corresponding to each sequence number of the receiving module; and the air conditioner determines the sequence number of the first signal with the most receiving times as the target sequence number.

[0086] In this way, the air conditioner obtains the receiving times of the first signal corresponding to each sequence number of the receiving module, and determines the sequence number of the first signal with the most receiving times as the target sequence number. Within the set time period, the more times the receiving module receives the first signal, the more it indicates that the sending module sending the first signal is the sending module of the current air conditioner, and therefore the sequence number in the first signal is taken as the target sequence 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 same as the target serial number; and the air conditioner receiving the first signal in the case of being same.

[0088] In this way, the air conditioner determines whether the serial number of the first signal is same as the target serial number, and receives the first signal in the case of being same. After determining the target serial number, the signal sent by the current air conditioner sending module can be screened out by screening the first signal with the same serial number as the target serial number, thereby avoiding the interference of signals of other sending modules.

[0089] Based on the structure of the air conditioner described above, as shown in Figure 4 The embodiment of the present disclosure provides a method for energy saving of an air conditioner, including:

[0090] S41, the air conditioner determines a first temperature threshold according to user habits in response to a control instruction of intelligent starting.

[0091] S42, the air conditioner calculates an absolute value of a temperature difference between an indoor environment temperature and a user set temperature.

[0092] S43, the air conditioner starts a power saving mode in the case that the absolute value is less than the first temperature threshold.

[0093] The user can actively start the intelligent starting function through an intelligent starting button on a remote controller or voice control and the like.

[0094] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure determines a first temperature threshold according to user habits in response to a control instruction of intelligent starting, and calculates an absolute value of a temperature difference between an indoor environment temperature and a user set temperature. The power saving mode is started in the case that the absolute value is less than the first temperature threshold. In addition to the air conditioner automatically entering energy saving operation based on a power supply environment, the intelligent starting mode of the power saving mode is set, the first temperature threshold is determined based on user habits, and the power saving mode is controlled to start based on the first temperature threshold and the indoor temperature difference, which fully considers the user's demand for the indoor temperature. The start and stop of the power saving mode can better meet the user's demand for the temperature compared to the automatic entering of the energy saving operation based on the power supply environment, and the balance between the user's demand and energy saving is achieved, thereby improving the user experience.

[0095] Optionally, the air conditioner determines the first temperature threshold according to user habits, including: the air conditioner obtaining first temperature data when the user actively starts the power saving mode within a set time; the air conditioner determining a first average temperature difference between the indoor environment temperature and the user set temperature according to the first temperature data; and the air conditioner determining the first average temperature difference as the first temperature threshold.

[0096] The active start of the power saving mode can be any mode such as the user pressing a button on a remote controller to start the power saving mode, the user starting the power saving mode through voice, or the user starting the power saving mode through gesture control.

[0097] In this way, the air conditioner obtains first temperature data when the user actively starts the power saving mode within a set time, and determines a first average temperature difference between the indoor environment temperature and the user set temperature according to the first temperature data, and finally determines the first average temperature difference as the first temperature threshold. Based on the temperature data in the room when the user actively starts the power saving mode, it can be determined that when the temperature difference between the indoor environment temperature and the user set temperature is how much, the user will tend to the power saving demand and actively start the power saving mode. Therefore, the first temperature threshold is matched with the user demand, and the accuracy of the start time of the power saving mode in the intelligent start control is improved.

[0098] Optionally, after the air conditioner responds to the intelligent start control instruction, the air conditioner further comprises: the air conditioner determines a second temperature threshold according to user habits; and the air conditioner closes 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 according to user habits, and closes the power saving mode when the absolute value is greater than the second temperature threshold. The second temperature threshold that meets the user demand is determined based on the user habits, so that the closing time of the power saving mode can be more accurate.

[0100] Optionally, the air conditioner determines a second temperature threshold according to user habits, comprising: the air conditioner obtains second temperature data when the user actively closes the power saving mode within a set time; the air conditioner determines a second average temperature difference between the indoor environment temperature and the user set temperature according to the second temperature data; and the air conditioner determines the second average temperature difference as the second temperature threshold.

[0101] In this way, the air conditioner obtains second temperature data when the user actively closes the power saving mode within a set time, and determines a second average temperature difference between the indoor environment temperature and the user set temperature according to the second temperature data, and finally determines the second average temperature difference as the second temperature threshold. Based on the temperature data in the room when the user actively closes the power saving mode, it can be determined that when the temperature difference between the indoor environment temperature and the user set temperature is how much, the user will tend to the temperature demand (close the power saving mode). Therefore, the first temperature threshold is matched with the user demand, and the accuracy of the start time of the power saving mode in the intelligent start control is improved.

[0102] Optionally, after the air conditioner responds to the intelligent start control instruction, the air conditioner further comprises: the air conditioner determines a second temperature threshold according to user habits; and the air conditioner closes the power saving mode when the absolute value is greater than the second temperature threshold.

[0103] The determination of whether to start the power saving mode according to the user feedback can be any interactive mode, for example, sending information to the client about whether to start the power saving mode or asking the user through voice and giving the user feedback to determine whether to start the power saving mode.

[0104] In this way, when the absolute value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, it is not possible to determine whether the user's demand is to save power or to change the temperature, so the air conditioner determines whether to start the power saving mode according to the user feedback, and interacts with the user, so that the user can better understand the intelligent control of the air conditioner and meet the user's demand for active power saving or changing the temperature.

[0105] Optionally, the air conditioner receives the control instruction for intelligent starting in the following manner: the air conditioner receives the control instruction for intelligent starting sent by the remote controller through an infrared module.

[0106] In this way, the air conditioner receives the control instruction for intelligent starting sent by the remote controller through the infrared module, and the infrared module can receive the instruction to avoid the situation that the power saving mode cannot be started when the receiving module is damaged, thereby improving the user experience.

[0107] Optionally, the method for the air conditioner to save energy further includes: when the power saving mode is not started and the power consumption exceeds the user-set power consumption, the air conditioner starts the power saving mode.

[0108] In this way, when the power saving mode is not started and the power consumption exceeds the user-set power consumption, the air conditioner starts the power saving mode, which can automatically detect the power consumption and start the power saving mode in time when the power consumption is excessive, thereby avoiding the user's frequent checking of the power consumption due to concern about excessive power consumption, and improving the user experience.

[0109] Based on the structure of the air conditioner described above, as shown in Figure 5 The present embodiment provides a method for the air conditioner to save energy, which includes the following steps when no control instruction for intelligent starting is received:

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

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

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

[0113] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure calculates a temperature difference value of an indoor environment temperature and a user set temperature. In a case where the temperature difference value is less than a first temperature threshold, the first power supply mode with the lowest cost is switched to. In a case where the temperature difference value is greater than a second temperature threshold, the second power supply mode with the highest stability is switched to. The power supply mode is switched based on the indoor temperature difference and the power consumption cost and stability of each power supply mode, fully considering the user's demand for temperature, the stability of the power supply environment and the power consumption cost, which can solve the problem of unstable operation of the air conditioner from the source, avoid the case where the air conditioner is always in an energy-saving operation state, and instead reduce the effect of the air conditioner on adjusting the environment, and improve the user experience.

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

[0115] In this way, the air conditioner sorts each power supply mode according to the cost data of each power supply mode uploaded by the user according to the cost size, and obtains the first power supply mode, which determines the first power supply mode based on the power consumption cost, meets the user's temperature demand, and also takes into account the saving of power consumption cost, thereby improving the user experience.

[0116] Optionally, the air conditioner determines the second power supply mode in the following manner, which includes: the air conditioner determines the voltage fluctuation degree of each power supply mode according to the voltage data within the set time length of each power supply mode; and the air conditioner sorts each power supply mode according to the fluctuation degree size, and obtains the second power supply mode.

[0117] In this way, the air conditioner determines the voltage fluctuation degree of each power supply mode according to the voltage data within the set time length of each power supply mode, and sorts each power supply mode according to the fluctuation degree size, and obtains the second power supply mode. The second power supply mode is determined based on the fluctuation degree size, so that the second power supply mode can preferentially meet the demand for stability of the power supply environment, thereby ensuring the effect of temperature adjustment of the air conditioner.

[0118] Optionally, the method for energy saving of the air conditioner further includes: the air conditioner comprehensively scores each power supply mode according to the cost size and the voltage fluctuation degree size of each power supply mode; and in a case where the temperature difference value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the air conditioner switches to a third power supply mode with the highest comprehensive score; wherein the cost and the score are negatively correlated, and the voltage fluctuation degree and the score are negatively correlated.

[0119] In this way, the air conditioner scores each power supply mode according to the cost and the voltage fluctuation, and switches to the third power supply mode with the highest score when the temperature difference is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold. Since the temperature difference is between the first temperature threshold and the second temperature threshold, there is no urgent temperature requirement and power saving requirement at this time, and therefore the air conditioner switches to the third power supply mode with the highest score to balance the power saving and temperature regulation, achieving both power saving and temperature regulation effect. 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 according to the order, and adds the scores of the power supply costs and voltage fluctuations of the same item to obtain the comprehensive score of each power supply mode.

[0120] Optionally, the air conditioner scores each power supply mode according to the cost and the voltage fluctuation, including: the air conditioner assigns a first score to each power supply mode according to the cost; the air conditioner assigns a second score to each power supply mode according to the voltage fluctuation; and the air conditioner adds the first score and the second score of each power supply mode to obtain the comprehensive score of each power supply mode.

[0121] In this way, the air conditioner assigns a first score to each power supply mode according to the cost, and assigns a second score to each power supply mode according to the voltage fluctuation, and finally adds the first score and the second score of each power supply mode to obtain the comprehensive score of each power supply mode. Based on the cost and the voltage fluctuation, the first score and the second score are assigned to obtain the comprehensive score, which can represent the cost value and stability of the power supply mode, so that the air conditioner can switch the power supply mode more accurately, and take into account the power saving and temperature regulation effect.

[0122] Based on the structure of the air conditioner described above, as shown in Figure 6 The present disclosure provides a method for energy saving of an air conditioner, which includes the following steps:

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

[0124] S62, in the case of a fire, the air conditioner controls the sending module to send a warning signal containing a fire serial number to the target receiving module.

[0125] S63, the air conditioner controls the receiving module to receive a second signal containing the fire serial number and starts the buzzer.

[0126] The target receiving module includes a receiving module and a receiving module of another air conditioner in the fire-affected area. The fire sequence number can be replaced by a flood sequence number or other disaster sequence number.

[0127] The method for energy saving of the air conditioner provided by the embodiment of the present disclosure is adopted. When the sending module is powered on, the first sequence number sent by the sending module is determined as the target sequence number, and the receiving module is controlled to only receive the first signal containing the target sequence number. In the case of 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 start the buzzer. When a fire occurs, by additionally setting a special sequence number of the fire, and by allowing all receiving modules to respond to the warning signal containing the fire sequence number, the limitation that the receiving module can only receive the signal sent by the corresponding sending module in the current air conditioner is broken. The situation that the receiving module of the air conditioner can only receive the signal sent by the matched sending module when a fire occurs is avoided, thereby realizing timely warning of the fire and protecting the life and property safety of the user.

[0128] Optionally, the air conditioner determines whether a fire occurs in the following manner: the air conditioner determines that a fire occurs when the indoor temperature is greater than a set temperature, the concentration of a set gas is greater than a set concentration, and the indoor brightness is greater than a set brightness; wherein the set gas includes carbon dioxide or carbon monoxide.

[0129] In this way, when the indoor temperature is greater than a set temperature, the concentration of a set gas is greater than a set concentration, and the indoor brightness is greater than a set brightness, the gas concentration generated by the fire is obviously higher than the normal value, and the temperature and brightness are higher, so the air conditioner can determine that a fire occurs.

[0130] Optionally, the air conditioner controls the sending module to send a warning signal containing a fire sequence number to the target receiving module, including: the air conditioner determines a target address bit according to the danger level of the fire; the air conditioner determines the receiving module at the target address bit as the target receiving module; and the air conditioner controls the sending module to send the warning signal to the target receiving module.

[0131] In this way, the air conditioner determines a target address bit according to the danger level of the fire, determines the receiving module at the target address bit as the target receiving module, and finally controls the sending module to send a warning signal to the target receiving module. Based on the danger level, the warning signal is sent to the target module, which can avoid the situation that the range of the sent warning signal is too large, causing users who are not threatened by the fire to feel disturbed.

[0132] Optionally, the air conditioner determines the target address bit according to the danger level of the fire, comprising: the air conditioner determines the danger level; the air conditioner determines the target floor number corresponding to the danger level according to a preset third relationship; and the air conditioner determines the target address bit according to the target floor number.

[0133] In this way, the air conditioner determines the danger level, and determines the target floor number corresponding to the danger level according to a preset third relationship, and finally determines the target address bit according to the target floor number. By determining the floor number corresponding to the danger level, the target address bit is determined, so that the sending range of the fire warning signal notification is matched with the area (floor number) threatened by the fire, thereby realizing accurate fire warning. For example, there are 1st floor to 30th floor in total, and address bits are set as 001, 002, 003, 004, 005, 006, 007, 008, etc. If a fire occurs at address bit 00X, the users on the 00X-3 to 00X+3 floors are notified, so even if a fire occurs, it will not affect other floors. Moreover, the range of notification (sending the warning signal to the receiving module) can be increased or decreased according to the size of the fire, for example, the fire danger level and the target floor corresponding relationship 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 danger level, comprising: the air conditioner detects the current indoor temperature; the air conditioner determines the temperature range in which the current temperature is located; and the air conditioner determines the danger level according to the temperature range.

[0135] In this way, the air conditioner detects the current indoor temperature, and determines the temperature range in which the current temperature is located, and finally determines the danger level according to the temperature range. Based on the temperature range in which the current temperature is located, the danger level is determined, and since the temperature range can represent the current fire size, the danger level can be adapted to the current fire, thereby achieving accurate warning.
