At present, there is a shortage of electricity in underdeveloped areas such as Iraq and Nigeria. In addition to the mains electricity supply, there are also town generators, community generators, and personal generators, but the cost of using them is high. Therefore, air conditioners with ECO energy-saving functions are very popular in the local area. At present, the air conditioner needs to be manually operated by the remote control to enter the ECO mode, but it cannot be operated in time at night when sleeping or when children/elderly people are alone at home, resulting in increased electricity costs. Therefore, how to realize the automatic entry of the air conditioner into the ECO mode has become a problem that needs to be solved urgently.

Related technology discloses an air conditioner energy-saving control method, including: receiving a power grid signal indicating tight power supply; and controlling the air conditioner to operate in an energy-saving mode based on the power grid signal indicating tight power supply.

In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

The related technology controls the air conditioner to automatically enter energy-saving operation when the power supply is tight, thereby achieving stable operation of the air conditioner.

In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process 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 the smart home appliances.

In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. The mobile device may include, for example, 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 include, for example, a Including: smart watches, smart bracelets, pedometers, etc.

The disclosed embodiment discloses an air conditioner, including: 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, and the serial number includes a first serial number and a special serial number for matching. The special serial number can be an arbitrarily 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 a control instruction to the control panel to control the air conditioner when the receiving module is damaged or abnormal.

Among them, after the receiving module successfully matches with the sending module, it only receives the signal containing the first serial number of the corresponding sending module and the signal containing the special serial number. Specifically, the sending module can send a signal to the receiving module by means of power line carrier communication. For example, when the sending module sends a signal, the data is modulated using modulation technology, and 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 first taken out through a filter, and then demodulated to obtain the original communication signal, which is then transmitted to the air conditioner control board to realize information transmission, thereby realizing intelligent control of the air conditioner.

Based on the structure of the air conditioner described above, as shown in FIG1 , an embodiment of the present disclosure provides a method for energy saving of an air conditioner, including:

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

S02: The air conditioner determines a target power saving mode according to a current power supply mode of the air conditioner.

S03, the air conditioner controls the operation of the air conditioner according to the target power saving mode.

The power supply mode includes any power supply mode, such as town power generation, community power generation, personal power generation, municipal power generation, etc.

The method for energy saving of an air conditioner provided by the embodiment of the present disclosure is adopted, in response to a power saving control instruction, the current power supply mode of the air conditioner is detected, and according to the current power supply mode of the air conditioner, a target power saving mode is determined, and finally the air conditioner is controlled 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, so that the energy saving control of the air conditioner meets the energy saving requirements under different power supply modes, and improves the energy saving effect of the energy saving control of the air conditioner.

Optionally, the air conditioner determines the target power saving mode according to the current power supply mode of the air conditioner, including: the air conditioner obtains 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.

In this way, the air conditioner obtains the electricity cost of different power supply modes, and determines the target power saving mode based on the current power supply mode and electricity cost. Determining the target power saving mode based on the electricity cost can match the target power saving mode with the electricity cost, thereby saving electricity more accurately and saving electricity cost.

Optionally, the air conditioner determines the target power saving mode according to the current power supply mode and the power cost, including: the air conditioner sorts different power supply modes according to the power cost to determine the cost ranking of the current power supply mode; the air conditioner selects the target power saving mode according to the preset first relationship, and determine the target power saving mode corresponding to the cost ranking.

Among them, the electricity cost of the current power supply mode is negatively correlated with the total power of the target power saving mode.

In this way, the air conditioner sorts different power supply modes according to the electricity cost, determines the cost ranking of the current power supply mode, and determines the target power saving mode corresponding to the cost ranking according to the preset first relationship. Through the cost ranking, the electricity cost of the current power supply mode in all power supply modes can be reflected, so that the target power saving mode that is most suitable for the current power supply mode can be determined from different power saving modes to achieve accurate energy saving. In addition, the power saving mode with higher electricity cost has lower power corresponding to the target power saving mode, so that the electricity cost can be controlled within the set cost range to avoid excessive electricity cost and poor user experience. For example, the total 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 relationship is: urban 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; among which, the L1 gear is 800W, the L2 gear is 1500W, the L3 gear is 2000W, and the L4 gear is 2500W.

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

In this way, the air conditioner detects the current voltage of the air conditioner's power supply and adjusts the operating frequency of the compressor according to the current voltage. When one of the power consumption environments, such as town power generation, community power generation, personal power generation, and municipal power generation, changes, that is, when the voltage is unstable, it may affect the normal operation of the air conditioner. Therefore, the air conditioner dynamically adjusts the operating frequency of the compressor according to the current voltage, thereby achieving the purpose of dynamic power management and ensuring the stable operation of the air conditioner.

Optionally, the air conditioner detects the current power supply mode of the air conditioner, including: the air conditioner responds to the power saving control instruction and determines a set period according to the current power supply mode; the air conditioner detects the current voltage at intervals of the set period.

In this way, the air conditioner responds to the power saving control instruction, determines the set period according to the current power supply mode, and detects the current voltage at intervals of the set period. Since different power supply modes are different, their instability standards are also different. Therefore, the air conditioner determines the corresponding set period based on different power supply modes to more accurately detect the stability of the power environment of different power supply modes.

Optionally, the air conditioner adjusts the operating frequency of the compressor according to the current voltage, including: the air conditioner obtains the standard voltage of the current power supply mode; the air conditioner calculates the voltage ratio of the current voltage to the standard voltage; the air conditioner adjusts the operating frequency of the compressor according to the voltage ratio.

In this way, the air conditioner obtains the standard voltage of the current power supply mode, calculates the voltage ratio of the current voltage to the standard voltage, and finally adjusts the operating frequency of the compressor according to the voltage ratio. Based on the ratio of the current voltage to the standard voltage, the current voltage is proportionally reduced or increased, thereby achieving stable operation of the air conditioner. Avoid the situation where the power environment is unstable, resulting in a reduction in the air conditioner's environmental adjustment effect.

Optionally, the air conditioner adjusts the operating frequency of the compressor according to the voltage ratio, including: the air conditioner calculates the voltage ratio The product of the target operating frequency and the standard operating frequency is determined as the target operating frequency; the air conditioner controls the compressor to operate according to the target operating frequency.

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

Optionally, the air conditioner controls the operation of the compressor according to the target operating frequency, including: the air conditioner adjusts the operating frequency of the compressor to the target operating frequency according to the voltage change rate of the power supply voltage.

The air conditioner adjusts the operating frequency of the compressor to the target operating 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 operating frequency of the compressor to the target operating frequency according to the first rate when the current voltage change rate is less than the standard voltage change rate; the air conditioner adjusts the operating frequency of the compressor to the target operating frequency according to the second rate when the current voltage change rate is greater than the standard voltage change rate;

Among them, 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 YHz; 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|.

In this way, the air conditioner adjusts the operating frequency of the compressor according to the voltage change rate of the power supply voltage, which can avoid the compressor operating frequency being adjusted too quickly and changing greatly, resulting in unstable compressor operating frequency and noise, thereby improving the user experience. For example, when the power supply voltage is detected to be 190V at the first time node and the power supply voltage is detected to be 200V after the interval setting period, the standard voltage change rate is 10, and the operating frequency needs to be adjusted from 46Hz (current) to 55Hz (target), and the frequency change value is 9Hz. If the current voltage change rate is below 10 (for example, 6V), the first rate is 15Hz. At this time, the operating frequency value of the compressor can reach the target operating frequency, and will not cause the compressor to cause noise due to too fast changes in frequency parameters, and can also achieve energy-saving effects.

Based on the structure of the air conditioner described above, as shown in FIG2 , the embodiment of the present disclosure provides a method for energy saving of an air conditioner. The air conditioner responds to a power saving control instruction, and before detecting the current power supply mode of the air conditioner, the method further includes:

S21, the air conditioner determines a sending cycle according to the current power supply mode of the air conditioner.

S22, when the power supply voltage of the air conditioner is stable, the sending module is controlled to send a first signal to the receiving module according to a sending cycle.

S23, the air conditioner starts the power saving mode when the receiving module fails to receive the first signal for a number of times greater than a set number of times.

The air conditioner starts the power saving mode specifically by the receiving module sending a power saving control instruction to the control board, so that the air conditioner responds to the power saving control instruction and performs the power saving operation. The air conditioner performs the power saving operation specifically by adopting the steps in the above-mentioned embodiment, which is not limited here. For example, the air conditioner determines the target power saving mode according to the current power supply mode; the air conditioner The air conditioner is controlled to operate according to the target power saving mode.

The method for energy saving of an air conditioner provided by the embodiment of the present disclosure is adopted, and the sending cycle is determined according to the current power supply mode of the air conditioner. When the power supply voltage is stable, the sending module is controlled to send a first signal to the receiving module according to the sending cycle, and when the receiving module does not receive the first signal for more than a set number of times, the power saving mode is started. Based on different power supply modes, the communication response mechanism corresponding to the current power supply mode is adopted to realize the start of the power saving mode, so that the start timing of the power saving mode matches the current power supply mode. When the power saving mode corresponding to different power supply modes is adopted for energy saving control, the power saving mode can be started in time under different power supply modes, thereby improving the energy saving effect of the energy saving control of the air conditioner. In addition, different sending cycles are set according to different power supply modes, so that the air conditioner can determine the current power supply mode in time, so that 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.

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.

In this way, the air conditioner determines the sending cycle corresponding to the current power supply mode according to the preset second relationship, so that the period of the sending module sending the first signal can match the current power supply mode. Since different power supply modes are different, the power supply environment is detected by the corresponding sending cycle to determine whether to start the power saving mode, which can make the timing of starting the energy saving control of the air conditioner more accurate.

Optionally, after the air conditioner determines the sending cycle according to the current power supply mode of the air conditioner, it also includes: the air conditioner detects the power supply voltage and obtains the standard voltage; the air conditioner determines 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; the air conditioner determines that the power supply voltage is unstable when the voltage difference is greater than or equal to the set error threshold.

In this way, the air conditioner detects the power supply voltage and obtains the standard voltage. When the voltage difference between the power supply voltage and the standard voltage is less than the set error threshold, the difference between the power supply voltage and the standard voltage is small, indicating that the fluctuation of the power supply voltage is low, so the power supply voltage is determined to be stable. When the voltage difference is greater than or equal to the set error threshold, the difference between the power supply voltage and the standard voltage is small, indicating that the fluctuation of the power supply voltage is high, so the power supply voltage is determined to be unstable.

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.

Thus, due to the differences between different power supply modes, for example, different stability, the standard voltages corresponding to the power supply modes will also be different. Thus, the air conditioner determines the standard voltage corresponding to the power supply mode according to the preset third relationship, so that the standard voltage can be adapted to each power supply mode, thereby improving the accuracy of the energy-saving operation start timing of the air conditioner.

Optionally, the air conditioner determines the set number of times in the following manner: the air conditioner determines the number of times corresponding to the power supply according to the current power supply mode. The number of settings corresponding to the method.

In this way, the air conditioner determines the set number of times corresponding to the current power supply mode according to the current power supply mode, and can match the set number of times with the current power supply mode, thereby increasing the accuracy of the energy-saving control startup timing.

Optionally, the method for saving energy for an air conditioner further includes: when the sending module of the air conditioner is powered on, controlling the display module to display a first color; when the power saving mode of the air conditioner is started, controlling the display module to display a second color.

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

In this way, when the sending module of the air conditioner is powered on, the display module is controlled to display the first color, and when the power saving mode is activated, the display module is controlled to display the second color. By displaying different colors, the user can clearly understand the activation time of the power saving mode of the air conditioner, so that the user can understand the process of intelligent control of the air conditioner, thereby enhancing the user experience.

Based on the structure of the air conditioner described above, as shown in FIG3 , the embodiment of the present disclosure provides a method for energy saving of an air conditioner, wherein the air conditioner controls the receiving module to match the sending module, including:

S31, when the sending module of the air conditioner is powered on, the sending module increases the frequency of sending the first signal within a set time period.

S32: The air conditioner control receiving module determines the sequence number of the first signal received with the highest frequency as the target sequence number.

S33, the air conditioner control receiving module receives a first signal including a target serial number.

Among them, before the air conditioner starts the power saving mode and the receiving module sends the power saving control instruction to the control board, for example, when the air conditioner is installed, when the sending module is installed, or when the sending module is repaired, the air conditioner needs to control the receiving module to match the sending module. 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 then sends the above information to the control board to control the operation of the air conditioner.

According to the method for energy saving of air conditioners provided by the embodiment of the present disclosure, when the sending module is powered on, the frequency of sending the first signal within the set time length of the sending module is increased, and the receiving module is controlled to determine that the sequence number of the first signal received with the highest frequency is the target sequence number, and finally the receiving module is controlled to receive the first signal containing the target sequence number. By increasing the frequency of sending signals sent by the sending module of the current air conditioner, the signals sent by the sending module of the current air conditioner can be screened out. Therefore, controlling the receiving module to receive signals with the target sequence number can enable the receiving module to only receive signals sent by the sending module of the current air conditioner. This avoids the situation where the receiving module of the air conditioner is interfered with by the signals of the sending modules of other air conditioners, resulting in misjudgment of the power supply mode and erroneous activation of the power saving mode, thereby improving the user experience.

Optionally, the air conditioner increases the frequency of sending the first signal within a set time period of the sending module, including: the air conditioner shortens the sending cycle of the first signal 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 cycle.

In this way, the air conditioner shortens the transmission cycle of the first signal sent by the sending module according to the set ratio, and controls the sending module to send the first signal according to the shortened transmission cycle. By shortening the transmission cycle, the efficiency of sending the first signal within the set time is increased. The frequency of the signal can be determined so that the receiving module can filter out the sending module in the current air conditioner from numerous signals for matching, thereby avoiding interference from the first signal sent by the sending module of other air conditioners.

Optionally, the air conditioner controls the receiving module to determine the serial number of the first signal received most frequently as the target serial number, including: the air conditioner obtains the number of times the first signal is received corresponding to each serial number of the receiving module; the air conditioner determines the serial number of the first signal received most times as the target serial number.

In this way, the air conditioner obtains the number of times the first signal is received corresponding to each serial number of the receiving module, and determines the serial number of the first signal with the largest number of receptions as the target serial number. Within the set time, the more times the first signal is received by the receiving module, the more likely it is that the sending module that sent the first signal is the sending module of the current air conditioner, so the serial number in the first signal is used as the target serial number for matching.

Optionally, the air conditioner controls the receiving module to receive a first signal including a target serial number, including: the air conditioner determines whether the serial number of the first signal is the same as the target serial number; and the air conditioner receives the first signal if they are the same.

In this way, the air conditioner determines whether the sequence number of the first signal is the same as the target sequence number, and receives the first signal if they are the same. After determining the target sequence number, the first signal with the same sequence number as the target sequence number is screened out, thereby being able to screen out the signal sent by the current air conditioner sending module, thereby avoiding signal interference from other sending modules.

Based on the structure of the air conditioner described above, as shown in FIG4 , an embodiment of the present disclosure provides a method for energy saving of an air conditioner, including:

S41, the air conditioner responds to the control instruction of intelligent start and determines a first temperature threshold according to user habits.

S42, the air conditioner calculates the absolute value of the temperature difference between the indoor ambient temperature and the temperature set by the user.

S43: When the absolute value is less than the first temperature threshold, the air conditioner starts the power saving mode.

Among them, users can actively activate the smart start function through the smart start button on the remote control or voice control.

The method for energy saving of an air conditioner provided by the embodiment of the present disclosure is adopted, and in response to the control instruction of intelligent start, the first temperature threshold is determined according to the user's habits, and the absolute value of the temperature difference between the indoor ambient temperature and the temperature set by the user is calculated. When the absolute value is less than the first temperature threshold, the power saving mode is started. In addition to the air conditioner automatically entering the energy-saving operation based on the power supply environment, an intelligent start mode of the power saving mode is set, the first temperature threshold is determined based on the user's habits, and the start of the power saving mode is controlled based on the first temperature threshold and the indoor temperature difference, which fully considers the user's demand for indoor temperature. Compared with automatically entering the energy-saving operation based on the power supply environment, the start and stop of the power saving mode can better take into account the user's demand for temperature, achieve a balance between user demand and energy saving, and improve the user experience.

Optionally, the air conditioner determines the first temperature threshold according to the user's habits, including: the air conditioner obtains the first temperature data when the user actively starts the power saving mode within the set time; the air conditioner determines the indoor environment temperature and The user sets a first average temperature difference of the temperature; the air conditioner determines the first average temperature difference as a first temperature threshold.

The active start of the power saving mode may be any method 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.

In this way, the air conditioner obtains the first temperature data when the user actively starts the power saving mode within the set time, and determines the first average temperature difference between the indoor ambient temperature and the user set temperature based on the first temperature data, and finally determines the first average temperature difference as the first temperature threshold. Based on the indoor temperature data when the user actively starts the power saving mode, it can be determined that when the user's indoor ambient temperature and the user set temperature differ by how much, he will tend to save power and actively start the power saving mode. In this way, the first temperature threshold is matched with the user's needs, and the accuracy of the timing of starting the power saving mode in the intelligent start control is improved.

Optionally, after the air conditioner responds to the control instruction of intelligent start, it also includes: the air conditioner determines a second temperature threshold according to user habits; the air conditioner turns off the power saving mode when the absolute value is greater than the second temperature threshold.

In this way, the air conditioner determines the second temperature threshold according to user habits, and turns off the power saving mode when the absolute value is greater than the second temperature threshold. The second temperature threshold that meets user needs is determined based on user habits, so that the timing of turning off the power saving mode can be more accurate.

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

In this way, the air conditioner obtains the second temperature data when the user actively turns off the power saving mode within the set time, and determines the second average temperature difference between the indoor ambient temperature and the user set temperature based on the second temperature data, and finally determines the 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 be determined that the user will tend to the temperature requirement (turn off the power saving mode) when the temperature difference between the indoor ambient temperature and the user set temperature differs by how much. In this way, the first temperature threshold is matched with the user's needs, and the accuracy of the power saving mode startup timing in the intelligent start control is improved.

Optionally, after the air conditioner responds to the control instruction of smart start, it also includes: when the absolute value is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the air conditioner determines whether to start the power saving mode according to user feedback.

Among them, judging whether to start the power saving mode according to user feedback can be any interactive method, for example, sending information on whether to start the power saving mode to the client or asking the user through voice, and giving the user feedback results to determine whether to start the power saving mode.

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 demand is inclined towards power saving or temperature. Therefore, whether to start the power saving mode is determined based on user feedback. By interacting with the user, the user can better understand the intelligent control of the air conditioner, and the user's demand for active power saving or temperature change can be met.

Optionally, the air conditioner receives the intelligent opening control instruction in the following manner: the air conditioner receives the intelligent opening control instruction issued by the remote controller through an infrared module.

In this way, the air conditioner receives the intelligent opening control command issued by 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 receiving module is damaged, thereby improving the user experience.

Optionally, the method for saving energy of the user's air conditioner further includes: when the air conditioner is not in the power saving mode and the power consumption exceeds the power set by the user, starting the power saving mode.

In this way, the air conditioner starts the power saving mode when the power consumption exceeds the user-set power. It automatically detects the power consumption and starts the power saving mode in time when the power consumption is too high. This avoids the user worrying about excessive power consumption and frequently checking the power consumption, thereby improving the user experience.

Based on the structure of the air conditioner described above, as shown in FIG5 , an embodiment of the present disclosure provides a method for energy saving of an air conditioner, which, when no intelligent start control instruction is received, includes:

S51, the air conditioner calculates the temperature difference between the indoor ambient temperature and the temperature set by the user.

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.

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.

The method for energy saving of the air conditioner provided by the embodiment of the present disclosure is used to calculate the temperature difference between the indoor ambient temperature and the temperature set by the user. When the temperature difference is less than the first temperature threshold, switch to the first power supply mode with the lowest cost. When the temperature difference is greater than the second temperature threshold, switch to the second power supply mode with the highest stability. Switching the power supply mode based on the indoor temperature difference and the electricity cost and stability of each power supply mode fully considers the user's demand for temperature, the stability of the power supply environment and the electricity cost, can solve the problem of unstable operation of the air conditioner from the source, avoids being in an energy-saving operation state all the time, and reduces the effect of the air conditioner in regulating the environment, thereby improving the user experience.

Optionally, the air conditioner determines the first power supply mode in the following manner, including: the air conditioner sorts the power supply modes according to cost size based on cost data of each power supply mode uploaded by the user to obtain the first power supply mode.

In this way, the air conditioner sorts the power supply modes according to the cost data of each power supply mode uploaded by the user, obtains the first power supply mode, and determines the first power supply mode based on the electricity cost. While meeting the user's temperature requirements, it also takes into account saving electricity costs and improves the user experience.

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

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 of each power supply mode. The power supply modes are sorted according to the fluctuation degree to obtain the second power supply mode. The second power supply mode is determined based on the fluctuation degree, so that the second power supply mode can preferentially meet the demand for power supply environment stability, thereby ensuring the temperature adjustment effect of the air conditioner.

Optionally, the method for saving energy for the air conditioner also includes: the air conditioner comprehensively scores each power supply mode according to the cost and voltage fluctuation of each power supply mode; when the temperature difference 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 the third power supply mode with the highest comprehensive score; wherein the cost is negatively correlated with the score, and the voltage fluctuation is negatively correlated with the score.

In this way, the air conditioner comprehensively scores each power supply mode according to the cost and voltage fluctuation of each power supply mode, and switches to the third power supply mode with the highest comprehensive 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 demand and power saving demand at this time. Therefore, the air conditioner switches to the third power supply mode with the highest comprehensive score to achieve a balance between power saving and temperature adjustment capabilities, thereby achieving power saving and ensuring the effect of temperature adjustment. 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 respectively according to the ranking, and adds the scores of the power supply costs and voltage fluctuations of the same items respectively to obtain the comprehensive scores of each power supply mode.

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

In this way, the air conditioner assigns a first score to each power supply mode according to the cost of each power supply mode, and assigns a second score to each power supply mode according to the voltage fluctuation of each power supply mode, and finally adds the first score and the second score of each power supply mode to obtain a comprehensive score of each power supply mode. The first score and the second score are assigned based on the electricity cost and the voltage fluctuation, respectively, to obtain a comprehensive score, which can make the comprehensive score 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 both power saving and temperature adjustment effects.

Based on the structure of the air conditioner described above, as shown in FIG6 , an embodiment of the present disclosure provides a method for energy saving of an air conditioner, which, when no intelligent start control instruction is received, includes:

S61, when the sending module of the air conditioner is powered on, the air conditioner determines that the first sequence number sent by the sending module is the target sequence number, and controls the receiving module to only receive the first signal including the target sequence number.

S62, when a fire occurs in the air conditioner, the control sending module sends a warning signal including a fire sequence number to a target receiving module.

S63, the air conditioner control receiving module receives the second signal including the fire sequence number and activates the buzzer.

The target receiving module includes a receiving module and receiving modules of other air conditioners in the fire affected area. The fire serial number can also be replaced by other disaster serial numbers such as flood serial numbers.

According to the method for energy saving of air conditioners provided by the embodiment of the present disclosure, when the sending module is powered on, the first sequence number sent by the sending module is determined to be the target sequence number, and the receiving module is controlled to receive only the first signal containing the target sequence number. In the event of a fire, the sending module is controlled to send an early warning signal containing the fire sequence number to the target receiving module, and the receiving module is controlled to receive the second signal containing the fire sequence number and start the buzzer. When a fire occurs, by additionally setting a special sequence number for the occurrence of a fire, and making all receiving modules respond to the early warning signal containing the fire sequence number, the limitation that the receiving module can only receive the signal of the corresponding sending module in the current air conditioner is broken. This avoids the situation where the receiving module of the air conditioner can only receive the signal sent by the matching sending module when a fire occurs, thereby achieving timely early warning of the fire and protecting the life and property of the user.

Optionally, the air conditioner determines whether a fire has occurred in the following manner: the air conditioner determines that a fire has occurred 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 luminosity is greater than a set luminosity; wherein the set gas includes carbon dioxide or carbon monoxide.

In this way, when the indoor temperature is greater than the set temperature, the concentration of the set gas is greater than the set concentration, and the indoor luminosity is greater than the set luminosity, the gas concentration generated by the fire obviously exceeds the normal value, and the temperature is high and the luminosity is large, so the air conditioner can determine that a fire has occurred.

Optionally, the air conditioner controls the sending module to send a warning signal containing a fire serial number to a target receiving module, including: the air conditioner determines the 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; the air conditioner controls the sending module to send the warning signal to the target receiving module.

In this way, the air conditioner determines the 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 the warning signal to the target receiving module. Sending the warning signal to the target module based on the danger level can avoid the situation where the range of the warning signal sent is too large, causing users who are not threatened by the fire to feel troubled.

Optionally, the air conditioner determines the target address bit according to the fire danger level, including: 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; the air conditioner determines the target address bit according to the target floor number.

In this way, the air conditioner determines the danger level, and according to the preset third relationship, determines the target floor number corresponding to the danger level, and finally determines the target address bit according to the target floor number. By determining the floor number corresponding to the danger level, and thus determining the target address bit, the sending range of the fire warning signal notification can be matched with the area (number of floors) threatened by the fire, thereby achieving accurate fire warning. For example, there are a total of 1st to 30th floors, and the address bits are set to 001, 002, 003, 004, 005, 006, 007, 008, etc., respectively. If a fire occurs at the address bit 00X, users on the floors 00X-3 to 00X+3 will be notified. Even if a fire occurs, it will not affect other floors. In addition, the scope of notification (sending warning signals to the receiving module) can be increased or decreased accordingly according to the size of the fire. For example, the corresponding relationship between the fire hazard level and the 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.

Optionally, the air conditioner determines the danger level, including: the air conditioner detects the current indoor temperature; the air conditioner determines the temperature range of the current temperature; the air conditioner determines the danger level according to the temperature range.

In this way, the air conditioner detects the current temperature in the room, determines the temperature range in which the current temperature is located, and finally determines the danger level based on the temperature range. Based on the temperature range in which the current temperature is located, the danger level is determined. Since the temperature range can characterize the current size of the fire, the danger level can be adapted to the current fire, thereby achieving accurate early warning.
