[0002] Currently, domestic household circuit breakers have fixed current limits for incoming current, while some overseas regions have varying ampere limits. When multiple electrical devices are used simultaneously, especially high-power devices, the total current consumption can easily exceed the ampere limit of the incoming current, leading to excessive current exceeding the circuit's limit, overheating and fires, or frequent overload and unexpected power outages for users with circuit breakers. Furthermore, in related technologies, large fluctuations or low current in the power supply can cause air conditioners to stop heating or cooling, resulting in a poor user experience. Summary of the Invention

[0040] In related technologies, when the power supply current fluctuates greatly or is low, the air conditioner may stop heating or cooling, resulting in a poor user experience.

[0041] The air conditioner provided in this embodiment of the invention is equipped with a power detection module, which enables the computer board to detect power fluctuations. After the air conditioner is turned on, the power detection module detects the real-time power status (including the real-time current entering the unit) and controls the machine to adjust the overall system to meet the normal control functions of the air conditioner.

[0042] The air conditioner also includes a notification component that can issue various notification messages to remind the user to perform corresponding operations.

[0043] The air conditioner provided in this embodiment of the invention can adapt to the current magnitude according to the user's instructions and operate normally after completing adaptive adjustment; it can also automatically detect and match to adapt to the current magnitude and operate normally.

[0044] After the air conditioner has been running stably, it receives a control mode switching signal, automatically shuts off the amperage function, activates the compensation setting, which requires that the unit not shut down, and provides real-time power feedback to the user.

[0045] Please refer to the current-limiting operation control method for an air conditioner provided in the first aspect embodiment of the present invention. Figure 1 ,include:

[0046] S100: Obtain the real-time operating frequency of the air conditioner and the real-time current entering the house.

[0047] It is understood that the air conditioner provided in this embodiment of the invention is equipped with a power detection module, which enables the computer board to detect power fluctuations. After the air conditioner is turned on, the power detection module detects the real-time current entering the household, thus determining the real-time power consumption of the household or unit. If the real-time current is large, it indicates that the user has many electrical devices with high power consumption, and the power consumption of the air conditioner needs to be adjusted accordingly to avoid exceeding limits. If the real-time current is small, it indicates that there are few electrical devices or the power consumption is low, and the operating power of the air conditioner can be adjusted appropriately to meet the user's needs as much as possible.

[0048] S200: Determine the current state of the air conditioner based on the real-time operating frequency, real-time current, pre-acquired gear current, and pre-acquired state correspondence, and control the operation of the air conditioner based on the current state.

[0049] In step S200, different combinations of real-time operating frequency, real-time current, and speed setting current correspond to the current state of the air conditioner. This state correspondence is pre-stored in the control program and can be recalled at any time. For example, when the relationship between a certain real-time operating frequency, real-time current, and speed setting current satisfies the condition of the state correspondence, the current state of the air conditioner can be determined as the state defined by the state correspondence. Since the current state defined by the state correspondence may affect the performance of the air conditioner, it is necessary to determine the operating mode of the air conditioner for each current state.

[0050] When the air conditioner provided in this embodiment of the invention is running, it first obtains the real-time operating frequency of the air conditioner and the real-time current entering the house. Then, it determines the current state of the air conditioner based on the real-time operating frequency, real-time current, pre-obtained gear current, and state correspondence. Based on the current state, it controls the operation of the air conditioner, which can maintain the stable operation of the air conditioner and maintain a high frequency as much as possible, resulting in a better user experience.

[0051] In this embodiment of the invention, the current state of the air conditioner includes at least overload state, low load state, overload state, and current limiting state, and the operating mode of the air conditioner needs to be adjusted in each current state.

[0052] According to one embodiment of the present invention, the step of obtaining the real-time operating frequency of the air conditioner and the real-time current entering the household further includes, prior to:

[0053] S101. Obtain the inbound current limit and determine the current level and status correspondence based on the inbound current limit and the pre-obtained current level relationship.

[0054] Understandably, the inbound current limit is a setting of the local power grid to prevent individual users from using excessively high-power appliances, thus avoiding total load overload and increasing the stability and safety of the power grid. When the air conditioner is first turned on, the inbound current limit can be manually entered, or its magnitude can be determined based on factors such as the region's geographic code. After the inbound current limit is determined, the current level of the inbound current limit can be determined based on its relationship with pre-acquired current level settings. This allows for the determination of the corresponding current level and its associated status. For example, if the inbound current limit is 10A, it falls into the first level, with a current of 9.5A. This current level is close to but lower than the inbound current limit. The status correspondence corresponds to multiple factors such as the current level, real-time current, and real-time operating frequency.

[0055] In some embodiments, please refer to Figure 2 The steps for determining the current state of the air conditioner based on real-time operating frequency, real-time current, pre-acquired gear current, and pre-acquired state correspondence, and controlling the operation of the air conditioner according to the current state, specifically include:

[0056] S210. When the real-time current is greater than the first proportion of the gear current and the real-time operating frequency is greater than the minimum operating frequency, it is determined that the current state of the air conditioner is overloaded. Then, the operating frequency of the air conditioner is reduced until the real-time current is equal to the first proportion of the gear current; wherein, the first proportion is less than 1.

[0057] It is understandable that when the real-time current exceeds the set current, an overcurrent power outage will occur. In order to maintain the stable operation of the air conditioner, the real-time current during operation generally does not exceed the first proportion of the set current. At this time, slight fluctuations in the real-time current will not affect the operation of the air conditioner. The air conditioner can maintain stable operation and high power operation, resulting in a high level of user comfort.

[0058] When the air conditioner is in an overload state, the operating frequency of the air conditioner is appropriately reduced. During this process, the real-time current is continuously monitored. When the real-time current equals the first proportion of the current setting, the operating frequency of the air conditioner is maintained at the current frequency. As can be seen from the above, when the real-time current equals the first proportion of the current setting, the air conditioner can not only maintain stable operation, but also maintain the highest operating frequency under the current current condition, thus meeting the user's cooling and heating needs as much as possible.

[0059] In some embodiments, the step of determining the current state of the air conditioner based on the real-time operating frequency, real-time current, pre-acquired gear current, and pre-acquired state correspondence, and controlling the operation of the air conditioner based on the current state, further includes:

[0060] S220. When the real-time current is less than the second ratio of the gear current, the current state of the air conditioner is determined to be a low-load state. Then, the operating frequency of the air conditioner is increased until the real-time current is equal to the first ratio of the gear current. Wherein, the second ratio is less than the first ratio.

[0061] Understandably, when the air conditioner is under low load, the operating frequency is appropriately increased while continuously monitoring the real-time current. When the real-time current equals a first proportion of the set current, the operating frequency is maintained at that frequency. Therefore, when the real-time current equals a first proportion of the set current, the air conditioner not only maintains stable operation but also maintains the highest possible operating frequency under the current current condition, thus meeting the user's cooling and heating needs as much as possible.

[0062] In some embodiments, the step of determining the current state of the air conditioner based on the real-time operating frequency, real-time current, pre-acquired gear current, and pre-acquired state correspondence, and controlling the operation of the air conditioner based on the current state, specifically includes:

[0063] S230. When the real-time operating frequency is at the lowest operating frequency and the real-time current is between the gear current and the first ratio of the gear current, it is determined that the current state of the air conditioner is overloaded. Then the control prompt component issues a prompt message to turn off other non-essential electrical appliances or shut down the air conditioner.

[0064] Understandably, when the real-time operating frequency is at its lowest setting and the real-time current is between the set current and the first ratio of the set current, it's impossible to maintain safe circuit operation by reducing the air conditioner's operating frequency. If the power of any appliance increases at this time, or a new electrical device is added, it will cause an overcurrent power outage. In this situation, the air conditioner is in an overload state. In one scenario, a prompt message can be issued to the user to turn off the air conditioner immediately, preventing continued operation and potential overcurrent power outages. In another scenario, a prompt message can be issued to turn off other non-essential appliances, allowing the air conditioner to continue operating while providing the user with more options.

[0065] In some embodiments, the step of determining the current state of the air conditioner based on the real-time operating frequency, real-time current, pre-acquired gear current, and pre-acquired state correspondence, and controlling the operation of the air conditioner based on the current state, specifically includes:

[0066] S240. When the real-time operating frequency is at the lowest operating frequency and the real-time current is greater than the gear current, the current state of the air conditioner is determined to be current limiting state, and the air conditioner is controlled to shut down directly.

[0067] Understandably, when the real-time operating frequency is at its lowest operating frequency and the real-time current is greater than the set current, the safe operation of the circuit cannot be maintained by further reducing the operating frequency of the air conditioner. In this case, the air conditioner can only be turned off to avoid overcurrent and power outage in the household circuit, thus improving the stability of the user's power supply.

[0068] In some embodiments, after the air conditioner is turned off, the control method further includes:

[0069] S231. When the real-time current meets the minimum operating current condition of the lowest operating frequency of the air conditioner, control the air conditioner to turn on automatically.

[0070] It is understandable that if the user turns off some electrical appliances while the air conditioner is off, the real-time current will decrease. The current when the air conditioner is operating at its lowest frequency is the minimum operating current. When the difference between the first ratio of the current setting and the real-time current is greater than the minimum operating current, restarting the air conditioner will not cause the real-time current to exceed the limit, and it can maintain stable operation. At this time, the air conditioner can be controlled to turn on automatically to meet the user's cooling and heating needs.

[0071] In some embodiments, the first ratio is between 70% and 95%, and the second ratio is between 10% and 60%. The first and second ratios are determined based on the stability of the local power grid. The more stable the power grid, the higher the first ratio, and the lower the likelihood of the air conditioner shutting down due to current fluctuations. When the real-time current is maintained at the first ratio of the set current, the air conditioner remains in a non-stop state and operates at the highest frequency, which can improve user comfort.

[0072] The current-limiting operation control method for air conditioners provided in this embodiment of the invention can achieve the following objectives by using adaptive power supply fluctuations:

[0073] (1) By inputting instructions through the controller, the unit can enter the ampere control program, which can make the air conditioner run at different current upper limits; or automatically detect the upper limit of the incoming current and automatically match different current control levels.

[0074] (2) Automatically adapt to the local power mode so that the air conditioner can operate in the best condition.

[0075] (3) The unit's operating current can be manually controlled to adaptively reduce energy consumption and achieve energy-saving effect.

[0076] (4) To solve the problem of unexpected power outages caused by the simultaneous use of multiple electrical devices, especially high-power electrical devices, due to the limitation of the incoming current.

[0077] (5) Solve the problem of fire caused by user current overload and line overheating.

[0078] (6) Under the premise of minimizing downtime, the machine can still be guaranteed to run at the highest frequency, ensuring the best cooling and heating effect.

[0080] The acquisition module 301 is used to acquire the real-time operating frequency of the air conditioner and the real-time current entering the house.
