In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0040] In the related art, when the power current fluctuates greatly or the current is low, the air conditioner will stop heating or cooling, and the user experience will be poor.

[0041] The air conditioner provided in the embodiment of the present invention is provided with a power detection module, and by adding the power detection module, the computer board has the function of detecting power fluctuations. After the air conditioner is turned on, the power detection module detects the real-time power status (including detecting the real-time current entering the house), and controls the machine to adjust the whole machine to meet the normal control function of the air conditioner.

[0042] The air conditioner also includes a prompt component, which can send out various prompt messages to remind the user to perform corresponding operations.

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

[0044] After the air conditioner is running stably, it receives the control switching mode, automatically turns off the ampere function, and turns on the compensation setting. The compensation setting needs to ensure that it does not stop and feedback the real-time power supply to the user.

[0045] According to the current limiting operation control method of the air conditioner provided by the embodiment of the first aspect of the present invention, please refer to 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 understandable that the air conditioner provided in the embodiment of the present invention is provided with a power detection module, and by adding the power detection module, the computer board has the function of detecting power fluctuations. After the air conditioner is turned on, the power detection module detects the real-time current entering the house, and the real-time power consumption of the household or unit can be determined. If the real-time current is large, it means that the user has more power-consuming devices at this time and the power is large, and the power consumption of the air conditioner needs to be considered as appropriate to avoid over-limit; if the real-time current is small, it means that the power consumption of the power-consuming devices is small or the power consumption is low, and the operating power of the air conditioner can be appropriately adjusted to meet the user's usage needs as much as possible.

[0048] S200, determining the current state of the air conditioner according to the real-time operating frequency, the real-time current, the pre-acquired gear current and the pre-acquired state correspondence, and controlling the operation of the air conditioner according to the current state.

[0049] In step S200, different combinations of real-time operating frequency, real-time current and gear current have corresponding relationships with the current state of the air conditioner, and the state corresponding relationship is pre-stored in the control program and can be called at any time when in use. For example, when the relationship between a certain real-time operating frequency, real-time current and gear current meets the condition of the state corresponding relationship, it can be determined that the current state of the air conditioner is the state defined by the state corresponding relationship, and the current state defined by the state corresponding relationship may affect the performance of the air conditioner, so it is necessary to determine the operation mode of the air conditioner for each current state.

[0050] When the air conditioner provided by the embodiment of the present invention is in operation, the real-time operating frequency of the air conditioner and the real-time current entering the house are first obtained, and then the current state of the air conditioner is determined according to the real-time operating frequency, the real-time current, the pre-acquired gear current and the state correspondence, and the operation of the air conditioner is controlled according to the current state. The air conditioner can be maintained in stable operation and at a higher frequency as much as possible, and the user experience is better.

[0051] In the embodiment of the present invention, the current state of the air conditioner includes at least an overload state, a low load state, an overload state, and a current limiting state, etc. In each current state, the operation mode of the air conditioner needs to be adjusted.

[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 house also includes:

[0053] S101, obtaining a household current limit, and determining a gear current and a state correspondence relationship according to the household current limit and a pre-acquired current gear relationship.

[0054] It is understandable that the household current limit is a setting of the local power grid to prevent a single user from using overpowered electrical appliances and causing total load overload, thereby increasing the stability and safety of the power grid. When the air conditioner is turned on for the first time, the household current limit can be manually entered, or the size of the household current limit can be confirmed based on the geographical number of the area. After the household current limit is determined, the gear of the current household current limit can be determined based on the relationship between the household current limit and the pre-acquired current gear, and the corresponding gear current and state correspondence can be determined. For example, if the household current limit is 10A, it falls into the first gear, the gear current is 9.5, and the gear current is close to but lower than the household current limit. The state correspondence corresponds to multiple factors such as the gear current, real-time current, and real-time operating frequency.

[0055] In some embodiments, see Figure 2 The steps of determining the current state of the air conditioner according to the real-time operating frequency, the real-time current, the pre-acquired gear current and the 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 an overload state, and the operating frequency of the air conditioner is controlled to decrease 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 is greater than the gear current, overcurrent power outage will occur. In order to maintain the stable operation of the air conditioner, the real-time current generally does not exceed the first proportion of the gear current when the air conditioner is running. 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 higher power operation, and the user's comfort is higher.

[0058] When the current state of the air conditioner is an overload state, the operating frequency of the air conditioner is controlled to be appropriately reduced, and the magnitude of the real-time current is continuously monitored during this process. When the real-time current is equal to the first proportion of the gear current, the operating frequency of the air conditioner is maintained at the current frequency. According to the above, when the real-time current is equal to the first proportion of the gear current, the air conditioner can not only maintain stable operation, but also maintain the highest operating frequency under the current current state, so as to meet 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 according to the real-time operating frequency, the real-time current, the pre-acquired gear current and the pre-acquired state correspondence, and controlling the operation of the air conditioner according to the current state further includes:

[0060] S220. When the real-time current is less than the second proportion of the gear current, it is determined that the current state of the air conditioner is a low-load state, and the operating frequency of the air conditioner is controlled to increase until the real-time current is equal to the first proportion of the gear current; wherein the second proportion is less than the first proportion.

[0061] It is understandable that when the current state of the air conditioner is a low-load state, the operating frequency of the air conditioner is controlled to increase appropriately, and the magnitude of the real-time current is continuously monitored during this process. When the real-time current is equal to the first proportion of the gear current, the operating frequency of the air conditioner is maintained at the current frequency. Based on the above, it can be seen that when the real-time current is equal to the first proportion of the gear current, the air conditioner can not only maintain stable operation, but also maintain the highest operating frequency under the current state, so as to meet the user's cooling and heating needs as much as possible.

[0062] In some embodiments, the steps of determining the current state of the air conditioner according to the real-time operating frequency, the real-time current, the pre-acquired gear current, and the pre-acquired state correspondence, and controlling the operation of the air conditioner according to the current state specifically include:

[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 an overload state, and the control prompt component sends a prompt message to turn off other non-essential electrical appliances or shut down.

[0064] It is understandable that 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 impossible to maintain the safe operation of the circuit by reducing the operating frequency of the air conditioner. If the power of any electrical appliance increases at this time, or a new electrical appliance is added, it will cause an overcurrent power outage in the circuit. At this time, the current state of the air conditioner is an overload state. In one case, a prompt message can be issued to prompt the user to shut down the air conditioner in time to avoid overcurrent power outage caused by continued operation of the air conditioner; in another case, a prompt message can be issued to shut down other non-essential electrical appliances. At this time, the operation of the air conditioner can still be maintained, giving users more choices.

[0065] In some embodiments, the steps of determining the current state of the air conditioner according to the real-time operating frequency, the real-time current, the pre-acquired gear current, and the pre-acquired state correspondence, and controlling the operation of the air conditioner according to the current state specifically include:

[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, it is determined that the current state of the air conditioner is a current limiting state, and the air conditioner is controlled to shut down directly.

[0067] It is understandable that when the real-time operating frequency is at the lowest operating frequency and the real-time current is greater than the gear current, the safe operation of the circuit cannot be maintained by continuing to lower the operating frequency of the air conditioner. At this time, the air conditioner can only be shut down to avoid overcurrent power outages in the household circuit, thereby improving the stability of user electricity consumption.

[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 air conditioner's minimum operating frequency, the air conditioner is controlled to automatically turn on.

[0070] It is understandable that if the user turns off some electrical appliances during the air conditioner shutdown period, the real-time current will decrease. The current of the air conditioner when it runs at the lowest frequency is the lowest operating current. When the difference between the first ratio of the gear current and the real-time current is greater than the lowest 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 automatically turn on 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 ratio and the second ratio are determined according to the stability of the local power grid. The more stable the power grid is, the higher the first ratio is, and the lower the possibility of the air conditioner shutting down due to current fluctuations is. When the real-time current is maintained at the first ratio of the gear current, the air conditioner is in a non-stop state and runs at the highest frequency, which can improve the user's comfort.

[0072] The current limiting operation control method of the air conditioner provided by the embodiment of the present invention can achieve the following objectives by using adaptive power supply fluctuations:

[0073] (1) By inputting instructions through the controller, the unit enters the ampere control program, which allows the air conditioner to operate according to different current upper limits; or automatically detect the upper limit of the household current and automatically match different current control gears for operation.

[0074] (2) Automatically adapt to local power modes so that the air conditioner can operate in the optimal state.

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

[0076] (4) Solve the problem of unexpected power outages caused by the simultaneous use of multiple electrical devices, especially high-power electrical devices, due to household current restrictions.

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

[0078] (6) While keeping the machine running as long as possible, the machine can also run at the highest frequency to ensure the best cooling and heating effects.
