Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically providing a control method for an air conditioner and an air conditioner. Background Technology

[0002] Currently, most air conditioners on the market have a forced defrost mode. When the air conditioner runs in heating mode for a preset time, it will trigger the forced defrost mechanism and put the air conditioner into forced defrost mode.

[0003] Current air conditioners typically activate the forced defrost mode immediately after triggering the forced defrost mechanism. However, under certain operating conditions, such as when both the indoor and outdoor units are running at high power and under heavy load, the air conditioner is prone to overcurrent shutdown protection. This occurs when the total current exceeds the set current, causing the air conditioner to shut down and impacting the user experience. Experiments have shown that when the air conditioner is running in heating mode, overcurrent shutdown protection is likely to trigger if the user-set target heating temperature exceeds the first preset temperature (e.g., 20°C) and the outdoor ambient temperature exceeds the second preset temperature (e.g., 15°C).

[0004] In existing technology, when the air conditioner runs in heating mode for a preset duration, it will trigger a forced defrosting mechanism and directly cause the air conditioner to execute the forced defrosting mode, which will lead to the problem of the air conditioner shutting down due to overcurrent protection, thus affecting the user experience.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to at least a certain extent solve the problem that the existing air conditioners have overcurrent shutdown protection when performing forced defrosting in heating mode, which affects the normal operation of the air conditioner and thus leads to a poor user experience.

[0007] In a first aspect, the present invention provides a control method for an air conditioner having a forced defrost mode. When the air conditioner is in heating mode, and the continuous operating time in heating mode exceeds a preset duration, the air conditioner enters the forced defrost mode. Before the air conditioner executes the forced defrost mode, the control method includes: acquiring a target temperature Ta set by a user in heating mode; and selectively causing the air conditioner to execute the forced defrost mode based on the target temperature Ta.

[0008] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively enabling the air conditioner to perform the forced defrosting mode according to the target temperature Ta" specifically includes: comparing the target temperature Ta with the first preset temperature T1; and selectively enabling the air conditioner to perform the forced defrosting mode according to the comparison result.

[0009] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively causing the air conditioner to perform the forced defrost mode according to the comparison result" specifically includes: if the target temperature Ta is less than the first preset temperature T1, then the air conditioner is caused to perform the forced defrost mode.

[0010] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively enabling the air conditioner to perform the forced defrost mode according to the comparison result" specifically includes: if the target temperature Ta is greater than or equal to the first preset temperature T1, then further obtaining the outdoor ambient temperature Tb where the outdoor unit of the air conditioner is located; comparing the outdoor ambient temperature Tb with the second preset temperature T2; and selectively enabling the air conditioner to perform the forced defrost mode according to the comparison result.

[0011] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively enabling the air conditioner to perform the forced defrosting mode according to the comparison result" specifically includes: if the outdoor ambient temperature Tb is greater than or equal to the second preset temperature T2, then acquiring the total current value I0 of the air conditioner at set intervals; comparing the total current value I0 with the first preset total current value I1; and selectively enabling the air conditioner to perform the forced defrosting mode according to the comparison result.

[0012] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively enabling the air conditioner to perform the forced defrosting mode according to the comparison result" specifically includes: if I0≥I1, then the air conditioner is not enabled to perform the forced defrosting mode.

[0013] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively causing the air conditioner to perform the forced defrosting mode according to the comparison result" specifically includes: if I0 < I1, then causing the air conditioner to perform the forced defrosting mode.

[0014] In the preferred embodiment of the control method for the air conditioner described above, after the air conditioner enters the forced defrosting mode, the control method further includes: adjusting the power of the air conditioner to perform the forced defrosting mode according to the total current value I0.

[0015] In the preferred embodiment of the control method for the air conditioner described above, the step of "selectively causing the air conditioner to perform the forced defrost mode according to the comparison results" specifically includes: if the outdoor ambient temperature Tb is less than the second preset temperature T2, then the air conditioner is caused to perform the forced defrost mode.

[0016] In a second aspect, the present invention provides an air conditioner including a controller configured to perform the control method for an air conditioner described above.

[0017] By adopting the above technical solution, the present invention can obtain the target temperature Ta set by the user before the air conditioner executes the forced defrost mode, and selectively enable the air conditioner to execute the forced defrost mode according to the target temperature Ta. This can avoid the air conditioner from stopping due to overcurrent protection when it is running under special operating conditions, thereby improving the user experience.

[0018] Furthermore, by comparing the target temperature Ta with the first preset temperature T1, the relationship between the two temperatures can be determined more intuitively. This allows for a more direct assessment of whether the air conditioner is operating under special conditions in heating mode, i.e., whether it is operating under high load pressure. Consequently, when the air conditioner is under special conditions, the forced defrosting mode is not activated to prevent overcurrent shutdown protection and subsequent shutdown. Conversely, when the air conditioner is not operating under special conditions, the forced defrosting mode is activated to defrost the air conditioner, preventing frost buildup from affecting its normal operation and further enhancing the user experience.

[0019] Furthermore, in heating mode, when the user-set target temperature Ta is less than the first preset temperature T1, it indicates that the indoor unit of the air conditioner is not operating under high load pressure. When the air conditioner reaches the condition for forced defrosting, executing the forced defrosting mode will not cause the air conditioner to shut down due to overcurrent. This ensures the normal operation of the air conditioner and allows for timely defrosting through forced defrosting, avoiding any impact on the heating effect of the air conditioner and further enhancing the user experience.

[0020] Furthermore, in heating mode, when the user-set target temperature is greater than or equal to the preset temperature, it indicates that the indoor unit of the air conditioner is operating under high load pressure. In this case, if the air conditioner is directly put into forced defrost mode after triggering the forced defrost mode, overcurrent shutdown protection may occur, affecting the normal use of the air conditioner. By further obtaining the ambient temperature of the outdoor unit and comparing the outdoor ambient temperature Tb with the second preset temperature T2, it is determined whether the outdoor unit of the air conditioner is operating under high load pressure, thereby determining whether the air conditioner is operating under power and high load pressure conditions, and then selectively putting the air conditioner into forced defrost mode.

[0021] Furthermore, if the outdoor ambient temperature Tb is greater than or equal to the second preset temperature T2, it indicates that the outdoor unit is also operating under high power and high load pressure. After triggering the forced defrost mode, directly enabling the air conditioner to execute the forced defrost mode may result in overcurrent shutdown protection. In this case, by further obtaining the total current value of the air conditioner and selectively enabling the air conditioner to execute the forced defrost mode based on the comparison result between the total current value and the first preset total current value, on the one hand, it can avoid the air conditioner from experiencing overcurrent shutdown protection, thereby avoiding affecting the normal operation of the air conditioner; on the other hand, it can enable the air conditioner to execute the defrost mode in a timely manner to defrost the air conditioner without the occurrence of overcurrent shutdown protection.

[0022] Furthermore, if I0 ≥ I1, it means that the current total current value I0 exceeds the first preset total current value I1. If the air conditioner is forced to defrost at this time, it is very likely to cause overcurrent shutdown protection and affect the user's use. Not enabling the air conditioner to execute forced defrost mode can avoid the air conditioner from experiencing overcurrent shutdown protection.

[0023] Furthermore, in the case where I0 < I1, this setting allows for the following scenario: in the case where I0 ≥ I1, the total current value exceeds the first preset total current value, and both the indoor and outdoor units of the air conditioner are operating under high power and high load pressure. In this case, the air conditioner is not forced to execute the defrost mode, which can prevent the air conditioner from experiencing overcurrent shutdown protection and thus avoid affecting the user experience due to the air conditioner shutting down.

[0024] Furthermore, when the outdoor ambient temperature Tb is less than the second preset temperature T2, it indicates that the outdoor unit is not operating under high power and high load pressure. In this case, the forced defrosting mode of the air conditioner can be deactivated, which can defrost the air conditioner in a timely manner without triggering overcurrent shutdown protection, thus further improving the user experience.

[0025] Furthermore, the air conditioner provided by the present invention, based on the above-described technical solution, possesses the beneficial effects of the aforementioned air conditioner due to the adoption of the control method described above. Compared with the air conditioner before the improvement, the air conditioner of the present invention is less likely to shut down due to overcurrent protection during long-term heating operation, has a better defrosting effect of forced defrosting, and provides a better user experience. Attached Figure Description

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which:

[0027] Figure 1 This is a flowchart of the control method of the present invention;

[0028] Figure 2 This is a flowchart of an embodiment of the control method of the present invention. Detailed Implementation

[0029] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Based on the technical issues mentioned in the background, existing air conditioners trigger a forced defrosting mechanism when the operating time in heating mode reaches a preset duration. However, when the air conditioner is operating under certain special conditions, such as when both the indoor and outdoor units are operating at high power and under high load pressure, directly forcing the air conditioner to perform defrosting can easily cause overcurrent shutdown protection, resulting in the machine failing to operate normally and affecting the user experience.

[0032] Experiments have shown that when an air conditioner is running in heating mode, if the user-set target heating temperature exceeds the set temperature (e.g., 20°C), the operating power of the indoor unit increases significantly, resulting in a higher load on the indoor unit. Similarly, if the outdoor ambient temperature exceeds the set temperature (e.g., 15°C), the operating power of the outdoor unit increases significantly, resulting in a higher load on the outdoor unit. When both the indoor and outdoor units are operating under high load conditions, the air conditioner is prone to overcurrent shutdown protection when performing forced defrosting.

[0033] To prevent the air conditioner from directly executing the forced defrost mode after triggering the forced defrost mechanism, which could lead to overcurrent shutdown protection, this invention provides a control method for air conditioners.

[0034] Please see Figure 1 , Figure 1This is a flowchart of the control method for the air conditioner of the present invention.

[0035] like Figure 1 As shown, the air conditioner of the present invention has a forced defrosting mode. When the air conditioner is in heating mode, if the continuous running time in heating mode exceeds a preset time, the air conditioner enters the forced defrosting mode. Before the air conditioner executes the forced defrosting mode, the control method of the present invention includes the following steps:

[0036] S1: Obtain the target temperature Ta set by the user in heating mode of the air conditioner;

[0037] S2: Selectively enable the air conditioner to perform forced defrosting mode based on the target temperature Ta.

[0038] By setting it up this way, before the air conditioner executes the forced defrost mode, the user-set target temperature Ta is obtained, and the forced defrost mode is selectively executed based on the target temperature Ta. This can prevent the air conditioner from stopping due to overcurrent protection under special operating conditions, thereby improving the user experience.

[0039] It should be noted that when an air conditioner enters forced defrost mode, it means that the forced defrost mechanism has been triggered. Before the air conditioner enters forced defrost mode, it means that the forced defrost mechanism has been triggered but has not yet been executed.

[0040] It should also be noted that, in practical applications, those skilled in the art can configure the air conditioner as a cabinet air conditioner, or as a wall-mounted air conditioner, or even as a window air conditioner, etc. Such adjustments and changes to the specific configuration type of the air conditioner do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0041] For example, the air conditioner is set up as a cabinet air conditioner.

[0042] It should be noted that, in practical applications, those skilled in the art can obtain the target temperature Ta based on the value entered by the user on the remote control connected to the air conditioner, or based on the value entered by the user through the buttons on the air conditioner, or based on the value entered by the user on the mobile device connected to the air conditioner, etc. Such adjustments and changes to the specific method of obtaining the target temperature Ta do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0043] Preferably, the target temperature Ta is obtained based on the value entered by the user on a remote control that is connected to the air conditioner.

[0044] It should be noted that, in practical applications, those skilled in the art can directly and selectively enable the air conditioner to execute the forced defrost mode based on the target temperature Ta. Alternatively, the target temperature Ta can be compared with the preset temperature, and the air conditioner can be selectively enabled to execute the forced defrost mode based on the comparison result, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0045] Continue reading Figure 2 , Figure 2 This is a flowchart of an embodiment of the control method of the present invention.

[0046] Preferably, such as Figure 2 As shown, the steps of "selectively enabling the air conditioner to perform forced defrost mode based on the target temperature Ta" specifically include:

[0047] S21: Compare the target temperature Ta with the first preset temperature T1;

[0048] S22: Based on the comparison results, selectively enable the air conditioner to perform forced defrosting mode.

[0049] By comparing the target temperature Ta with the first preset temperature T1, the relationship between the two temperatures can be determined more intuitively. This allows for a clearer assessment of whether the air conditioner is operating under special conditions in heating mode, specifically whether the indoor unit is operating at high power and high load pressure. This prevents the air conditioner from shutting down due to overcurrent protection. When the air conditioner is not operating under special conditions, it can be forced to defrost, preventing excessive frost buildup from affecting normal operation and further enhancing the user experience.

[0050] It should be noted that in practical applications, those skilled in the art can set the specific value of the first preset temperature T1 based on experience, or they can set the specific value of the first preset temperature T1 based on experiments, etc. Such adjustments and changes to the specific setting of the first preset temperature T1 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0051] Preferably, the specific value of the first preset temperature T1 is set based on the experiment.

[0052] For example, the first preset temperature T1 is set to 20°C.

[0053] It should be noted that, according to the test, when the user-set target temperature Ta is higher than 20℃, the operating power of the indoor unit of the air conditioner increases significantly, and the load pressure of the air conditioner is relatively large. Under this operating condition, the air conditioner is prone to overcurrent shutdown protection and will shut down.

[0054] It should also be noted that the first preset temperature T1 is not limited to 20°C. For example, the first preset temperature T1 may vary when testing in different regions. Those skilled in the art can test the first preset temperature T1 according to the actual situation.

[0055] It should be noted that in practical applications, the method is not limited to directly comparing the target temperature Ta with the first preset temperature T1 and selectively executing the forced defrost mode based on the comparison result. For example, the difference between the target temperature Ta and the first preset temperature T1 can be calculated first, and then the difference can be compared with the preset value. Based on the comparison result, the forced defrost mode can be selectively executed. Alternatively, the ratio of the target temperature Ta to the first preset temperature T1 can be calculated first, and then the ratio can be compared with the preset value. Based on the comparison result, the forced defrost mode can be selectively executed, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should be included within the protection scope of this invention.

[0056] Preferably, the target temperature Ta is compared with the first preset temperature T1, and based on the comparison result, the air conditioner is selectively made to perform a forced defrost mode.

[0057] Preferably, such as Figure 2 As shown, the steps of "selectively enabling the air conditioner to perform forced defrost mode based on the comparison results" specifically include:

[0058] S221: If the target temperature Ta is less than the first preset temperature T1, the air conditioner will be forced to defrost.

[0059] With this setting, in heating mode, when the user-set target temperature Ta is less than the first preset temperature T1, it indicates that the indoor unit of the air conditioner is not operating under high load pressure. When the air conditioner reaches the condition for forced defrosting, executing the forced defrosting mode will not cause the air conditioner to shut down due to overcurrent protection. This ensures the normal operation of the air conditioner and allows for timely defrosting by executing forced defrosting, avoiding any impact on the heating effect and further improving the user experience.

[0060] Preferably, such as Figure 2 As shown, the steps of "selectively enabling the air conditioner to perform forced defrost mode based on the comparison results" specifically include:

[0061] S2221: If the target temperature Ta is greater than or equal to the first preset temperature T1, then the outdoor ambient temperature Tb of the outdoor unit of the air conditioner is further obtained.

[0062] S2222: Compare the outdoor ambient temperature Tb with the second preset temperature T2;

[0063] S2223: Based on the comparison results, selectively enable the air conditioner to perform forced defrosting mode.

[0064] With this setting, in heating mode, when the user-set target temperature Ta is greater than or equal to the first preset temperature T1, it indicates that the indoor unit of the air conditioner is operating under high load pressure. If the air conditioner is directly put into forced defrost mode at this time, it is very likely that overcurrent shutdown protection will occur, affecting the normal use of the air conditioner. By further obtaining the outdoor ambient temperature Tb where the outdoor unit of the air conditioner is located, and comparing the outdoor ambient temperature Tb where the outdoor unit is located with the second preset temperature T2, it is determined whether the outdoor unit of the air conditioner is operating under high load pressure, thereby determining whether the air conditioner is operating under power and high load pressure conditions, and then selectively putting the air conditioner into forced defrost mode.

[0065] It should be noted that, in practical applications, those skilled in the art can obtain the outdoor ambient temperature Tb by setting a temperature detection component on the casing of the outdoor unit and obtaining the outdoor ambient temperature Tb by the detection value of the temperature detection component, or by setting a temperature detection component on the coil of the outdoor unit and obtaining the outdoor ambient temperature Tb by the detection value of the temperature detection component, etc. Such adjustments and changes to the specific method of obtaining the outdoor ambient temperature Tb do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0066] Preferably, a temperature detection component is installed on the casing of the outdoor unit, and the outdoor ambient temperature Tb is obtained by detecting the value of the temperature detection component.

[0067] It should be noted that, in practical applications, those skilled in the art can set the temperature detection component as a temperature sensor, or as a thermometer, etc. Such adjustments and changes to the specific setting type of the temperature detection component do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0068] Preferably, the temperature detection component is configured as a temperature sensor.

[0069] It should be noted that in practical applications, the method is not limited to directly comparing the outdoor ambient temperature Tb with the second preset temperature T2 and selectively executing the forced defrost mode based on the comparison result. For example, the difference between the outdoor ambient temperature Tb and the second preset temperature T2 can be calculated first, and then compared with the preset value. Based on the comparison result, the air conditioner can be selectively executed in a forced defrost mode. Alternatively, the ratio of the outdoor ambient temperature Tb to the second preset temperature T2 can be calculated first, and then compared with the preset value. Based on the comparison result, the air conditioner can be selectively executed in a forced defrost mode, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention.

[0070] Preferably, the outdoor ambient temperature Tb is directly compared with the second preset temperature T2, and the air conditioner is selectively forced to perform the defrost mode based on the comparison result.

[0071] With this setting, it is possible to more intuitively determine the difference between the outdoor ambient temperature Tb and the second preset temperature T2, thereby making it easier to determine whether the outdoor unit of the air conditioner is operating under high power and high load pressure conditions.

[0072] Preferably, such as Figure 2 As shown, the steps of "selectively enabling the air conditioner to perform forced defrost mode based on the comparison results" specifically include:

[0073] S222311: If the outdoor ambient temperature Tb is greater than or equal to the second preset temperature T2, the total current value I0 of the air conditioner is obtained at set intervals.

[0074] S222312: Compare the total current value I0 with the first preset total current value I1;

[0075] S222313: Based on the comparison results, selectively enable the air conditioner to perform forced defrosting mode.

[0076] With this setting, if the outdoor ambient temperature Tb is greater than or equal to the second preset temperature T2, it indicates that the outdoor unit is also operating under high power and high load pressure. Directly executing the forced defrost mode on the air conditioner may trigger overcurrent shutdown protection. In this case, by further obtaining the total current value of the air conditioner and selectively executing the forced defrost mode based on the comparison result between the total current value and the first preset total current value, the air conditioner can be prevented from triggering overcurrent shutdown protection, thus avoiding affecting the normal operation of the air conditioner. On the other hand, it can promptly execute the defrost mode to defrost the air conditioner without triggering overcurrent shutdown protection.

[0077] It should be noted that, in practical applications, those skilled in the art can obtain the total current value of the air conditioner by setting up a phase current acquisition module, or by obtaining the total current value of the air conditioner based on the value displayed on the air conditioner's computer board, etc. Such adjustments and changes to the specific method of obtaining the total current value of the air conditioner do not deviate from the principles and scope of this invention, and should all be included within the protection scope of this invention.

[0078] For example, the total current value of the air conditioner can be obtained from the values ​​displayed on the air conditioner's control board.

[0079] It should be noted that, in practical applications, those skilled in the art can set the specific duration of the time setting based on experience or experimentation.

[0080] For example, the specific duration of the set time is obtained based on experience. The set time is 5 minutes, that is, the total current value of the air conditioner is obtained every 5 minutes.

[0081] It should also be noted that in practical applications, those skilled in the art can obtain the specific value of the first preset total current value I1 based on experience, or they can obtain the specific value of the first preset total current value I1 based on experiments, etc. Such adjustments and changes to the specific setting of the first preset total current value I1 do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0082] Preferably, the specific value of the first preset total current value I1 is obtained based on the experiment.

[0083] For example, the first preset total current value I1 is 10A.

[0084] That is, when the total current value I0 of the air conditioner is greater than 10A, overcurrent shutdown protection may occur.

[0085] Preferably, such as Figure 2 As shown, the step of "selectively enabling the air conditioner to execute the forced defrost mode based on the comparison results" specifically includes:

[0086] S2223131: If I0≥I1, then the air conditioner will not be forced to perform the defrost mode.

[0087] With this setting, when I0≥I1, it means that when the total current value I0 of the air conditioner exceeds the first preset total current value I1, and both the indoor and outdoor units of the air conditioner are in a high-power, high-load pressure condition, the air conditioner will not be forced to execute the defrost mode. This can prevent the air conditioner from experiencing overcurrent shutdown protection, thereby avoiding the impact on the user experience due to the air conditioner shutting down.

[0088] Preferably, such as Figure 2 As shown, the specific steps for "selectively enabling the air conditioner to perform forced defrost mode based on the comparison results" include:

[0089] S2223132: If I0 < I1, then the air conditioner will be forced to defrost.

[0090] With this setting, when I0 < I1, it means that the current total current value I0 is lower than the first preset total current value I1. At this time, the air conditioner will execute the forced defrosting mode, which can defrost the air conditioner in time. At the same time, in this case, the overcurrent shutdown protection will not occur, so as to avoid affecting the user experience.

[0091] Preferably, such as Figure 2 As shown, the steps of "selectively enabling the air conditioner to perform forced defrost mode based on comparison results" specifically include:

[0092] S22232: If the outdoor ambient temperature Tb is less than the second preset temperature T2, the air conditioner will be forced to defrost.

[0093] With this setting, when the outdoor ambient temperature Tb is less than the second preset temperature T2, it means that the outdoor unit is not operating under high power and high load pressure. In this case, the air conditioner will execute the forced defrost mode, which can defrost the air conditioner in time and will not cause overcurrent shutdown protection, further improving the user experience.

[0094] The specific embodiments of the present invention will be described in detail below with reference to the following scenarios.

[0095] Set T1 = 20℃, T2 = 15℃, and I1 = 10A.

[0096] Scenario 1:

[0097] If the user-set target temperature Ta = 18℃ is detected, then Ta < T1, and the air conditioner will execute the forced defrost mode.

[0098] Scenario 2:

[0099] If the user-defined target temperature Ta = 20℃ is detected, then Ta = T1, and the outdoor ambient temperature Tb is further obtained.

[0100] (1) If Tb = 13℃ and Tb < T2, then the air conditioner should be put into forced defrosting mode;

[0101] (2) If Tb = 15℃ and Tb = T2, then further obtain the total current value I0 of the air conditioner.

[0102] (3) If Tb = 18℃ and Tb > T2, then further obtain the total current value I0 of the air conditioner.

[0103] If the total current value of the air conditioner is detected as I0 = 7A, then the air conditioner will be forced to execute the defrost mode.

[0104] If the total current value of the air conditioner I0 is detected to be 10A, then the air conditioner will not be forced to execute the defrost mode.

[0105] If the total current value of the air conditioner is detected as I0 = 12A, the air conditioner will not be forced to execute the defrost mode.

[0106] Scenario 3:

[0107] If the user-defined target temperature Ta = 23℃ is detected, then Ta > T1, and the outdoor ambient temperature Tb is further obtained.

[0108] (1) If Tb = 13℃ and Tb < T2, then the air conditioner should be put into forced defrosting mode;

[0109] (2) If Tb = 15℃ and Tb = T2, then further obtain the total current value I0 of the air conditioner.

[0110] (3) If Tb = 18℃ and Tb > T2, then further obtain the total current value I0 of the air conditioner.

[0111] If the total current value of the air conditioner is detected as I0 = 7A, then the air conditioner will be forced to execute the defrost mode.

[0112] If the total current value of the air conditioner I0 is detected to be 10A, the air conditioner will not be forced to execute the defrost mode.

[0113] If the total current value of the air conditioner is detected as I0 = 12A, then the air conditioner will not be forced to execute the defrost mode.

[0114] It should be noted that in practical applications, those skilled in the art can perform forced defrosting with the same set power, or they can adjust the power of the forced defrosting mode according to the total current value I0, etc. Such adjustments and changes to the specific setting of the defrosting power in the forced defrosting mode do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0115] Preferably, after the air conditioner enters the forced defrost mode, the control method of the present invention further includes:

[0116] Adjust the power of the air conditioner to perform forced defrosting mode based on the total current value I0.

[0117] By adjusting the power of the air conditioner in forced defrosting mode according to the total current value I0, compared with the method of directly performing forced defrosting at the same set power, this setting allows for flexible adjustment of the power of the air conditioner in forced defrosting mode based on the current total current value I0. This enables high-power forced defrosting to be activated when the total current value I0 is low, thereby improving defrosting efficiency, and low-power forced defrosting to be activated when the total current value I0 is high, avoiding overcurrent shutdown protection of the air conditioner and further enhancing the user experience.

[0118] It should be noted that, in practical applications, those skilled in the art can compare the total current value I0 with the second preset current value I2, and adjust the power of the air conditioner to perform the forced defrost mode based on the comparison result. Alternatively, the power of the air conditioner to perform the forced defrost mode can be adjusted based on experience or experimentation, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0119] Preferably, the step of "adjusting the power of the air conditioner to perform forced defrosting mode according to the total current value I0" ​​specifically includes:

[0120] Compare the total current value I0 with the second preset total current value I2;

[0121] Based on the comparison results, adjust the power of the air conditioner to perform the forced defrost mode;

[0122] Where 0 < I2 < I1.

[0123] With this setting, high-power defrosting can be performed when the total current value I0 is lower than the second preset total current value I2, improving defrosting efficiency and effect. When the total current value I0 is higher than the second preset total current value I2, low-power defrosting can be performed to avoid overcurrent shutdown protection during high-power defrosting, further enhancing the user experience.

[0124] Preferably, the step of "adjusting the power of the air conditioner to perform forced defrost mode based on the comparison results" specifically includes:

[0125] If I2 < I0 < I1, then the power of the air conditioner in forced defrosting mode will be adjusted to the first preset power P1;

[0126] If I0≤I2, then the power of the air conditioner in forced defrosting mode will be adjusted to the second preset power P2;

[0127] Where P1 < P2.

[0128] With this setting, on the one hand, when the total current value I0 is between the first preset total current value I1 and the second preset total current value I2, the power of the air conditioner to perform forced defrosting mode is adjusted to the first preset power P1, which enables the air conditioner to defrost at a lower power, avoiding excessive defrosting power and further increasing the operating load of the air conditioner, thereby preventing the air conditioner from experiencing overcurrent shutdown protection; on the other hand, when the total current value I0 is less than the second preset total current value I2, it indicates that the total current value I0 of the air conditioner is low at this time, and adjusting the power of the air conditioner to perform forced defrosting mode to the second preset power P2 can improve defrosting efficiency and defrosting effect.

[0129] It should be noted that in practical applications, the method is not limited to comparing the total current value I0 with the second preset total current value I2 and adjusting the power of the air conditioner in forced defrosting mode to the first preset power P1 or the second preset power P2 based on the comparison result. For example, the total current value I0 can be compared with multiple preset total current values, and the power of the air conditioner in forced defrosting mode can be adjusted to multiple power levels based on the comparison result, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention. Of course, preferably, the total current value I0 is compared with the second preset total current value I2, and the power of the air conditioner in forced defrosting mode is adjusted to the first preset power P1 or the second preset power P2 based on the comparison result.

[0130] It should also be noted that, in practical applications, those skilled in the art can set the specific value of the second preset total current value I2 based on experience or experimentation.

[0131] For example, the second preset total current value I2 = 5A.

[0132] It should be noted that in practical applications, those skilled in the art can set the specific values ​​of the first preset power P1 and the second preset power P2 based on experience or experimentation.

[0133] For example, the first preset power P1 = 300W; the second preset power P2 = 450W.

[0134] The following describes in detail specific embodiments of the power adjustment of the air conditioner of the present invention when performing forced defrosting mode, in conjunction with the following scenarios.

[0135] Set I1 = 10A, I2 = 5A, P1 = 300W, P2 = 450W.

[0136] Scenario 1:

[0137] If the total current value of the air conditioner is detected as I0 = 3A, then the power of the air conditioner in forced defrosting mode will be adjusted to 450W.

[0138] Scenario 2:

[0139] If the total current value of the air conditioner is detected as I0 = 5A, then the power of the air conditioner in forced defrosting mode will be adjusted to 450W.

[0140] Scenario 3:

[0141] If the total current value of the air conditioner is detected as I0 = 7A, then the power of the air conditioner in forced defrosting mode will be adjusted to 300W.

[0142] In addition, the present invention also provides an air conditioner including a controller configured to perform the control method described above.

[0143] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
