[0023] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0025] In order to solve the problem in the related art that the air conditioner may be interfered with by the grid voltage fluctuation, resulting in the air conditioner being misprotected, the present application provides an air conditioner anti-interference control method, such as Figure 1 As shown, the steps of the method include:

[0026] Step 101: When the air conditioner stops, determine whether the reason for the stop is overcurrent protection.

[0027] In the embodiment of the present application, when the air conditioner is shut down for protection, it is first determined whether it is overcurrent protection. If it is not overcurrent protection, the air conditioner is shut down for protection according to the original air conditioner control logic, and after-sales personnel can come to repair it. If it is overcurrent protection, the anti-interference control logic in the embodiment of the present application can be activated. Furthermore, the types of overcurrent protection include compressor overcurrent, fan overcurrent, PFC overcurrent, AC overcurrent protection, etc. Different overcurrent protections correspond to different protection pins of the main chip. In addition to key protection pins, the main chip has pins with other functions.

[0028] Step 102: If the shutdown reason is overcurrent protection, adjust the filter depth value of the protection pin of the main chip in the air conditioner, and restart the air conditioner after the adjustment;

[0029] In the embodiment of the present application, different filter depth values ​​correspond to different anti-interference capabilities. The higher the filter depth value, the stronger the corresponding interference resistance. Therefore, when it is determined that the current shutdown cause is caused by overcurrent protection, the filter depth value of the corresponding protection pin can be further adjusted to improve the current air conditioner's interference resistance. However, the anti-interference ability of the protection pin is limited. That is, if the filter depth value of the protection pin is adjusted to the maximum value, and there is still a shutdown caused by overcurrent protection, the second anti-interference method in the embodiment of the present application is required.

[0030] Step 103: After the filter depth value of the protection pin is adjusted to the maximum and the air conditioner is restarted, if the air conditioner still shuts down due to overcurrent protection, the capacitance value of the protection pin of the main chip in the air conditioner is adjusted.

[0031] In this regard, if adjusting the filter depth value of the protection pin cannot make the air conditioner operate normally due to overcurrent protection, it is necessary to further adjust the capacitance value of the corresponding main chip protection pin to further improve the anti-interference ability of the air conditioner main chip based on the filter depth value.

[0032] Through the above steps 101 to 103, in the embodiment of the present application, if the current air conditioner is shut down due to overcurrent protection, the filter depth value of the protection pin of the air conditioner main chip can be adjusted, and the air conditioner can be restarted again after the adjustment. If the air conditioner can operate normally after adjusting the filter depth value of the protection pin, it means that the anti-interference of the overcurrent protection can be completed by adjusting the filter depth value. If the air conditioner still shuts down due to overcurrent protection after adjusting the filter depth value of the protection pin, the capacitance value of the protection pin of the main chip can be further adjusted to further improve the anti-interference ability of the air conditioner. It can be seen that through the above-mentioned adjustment of the filter depth value of the main chip protection pin and the capacitance value of the main chip protection pin in the embodiment of the present application, the anti-interference ability of the air conditioner is greatly improved on the double-layer anti-interference mechanism, which can further stabilize the operating state of the air conditioner and solve the problem in the related art that the air conditioner is subject to corresponding interference due to grid voltage fluctuations, resulting in false protection of the air conditioner.

[0033] In the embodiment of the present application, the main chip uses different protection pins to provide different types of overcurrent protection. Therefore, before adjusting the filter depth value, the current overcurrent protection type must be determined, and then the corresponding protection pin can be determined. Therefore, before adjusting the filter depth value of the protection pin of the main chip in the air conditioner, the method of the embodiment of the present application may also include:

[0034] Step 11: When the shutdown reason is overcurrent protection, determine the type of overcurrent protection, and determine the protection pin of the corresponding main chip according to the type of overcurrent protection.

[0035] In a specific example, the types of overcurrent protection include compressor overcurrent, fan overcurrent, PFC overcurrent, AC overcurrent protection, etc. If the protection pin corresponding to the compressor overcurrent is pin 1, the protection pin corresponding to the fan overcurrent is pin 2, etc.

[0036] In the embodiment of the present application, the preset minimum value of the filter depth value refers to a preset minimum value further increased based on the filter depth value of the current protection pin. By gradually increasing the filter depth value based on the initial filter depth value, the anti-interference capability of the air conditioner is further improved. Based on this, the method involved in step 102 of the embodiment of the present application for adjusting the filter depth value of the protection pin of the main chip in the air conditioner and restarting the air conditioner after the adjustment can further include:

[0037] Step 21, increasing the filter depth value of the protection pin of the main chip in the air conditioner from a preset minimum value, restarting the air conditioner once each time the value is increased, until the air conditioner operates normally after restarting; or

[0038] Step 22: until the filter depth value of the protection pin of the main chip in the air conditioner increases to a preset maximum value, the air conditioner is still in the shutdown state when it is restarted.

[0039] Through steps 21 and 22 above, after a shutdown caused by overcurrent protection occurs, the type of overcurrent protection is first determined, and then the protection pin for which the filter depth value needs to be adjusted is determined. Furthermore, based on the current filter depth value, the corresponding filter depth value is gradually increased. In this embodiment of the present application, multiple filter depth values ​​that need to be increased can be set, starting from a preset minimum filter depth value and increasing sequentially. Each time the filter depth value is increased, the air conditioner is restarted to determine whether the air conditioner is no longer in overcurrent protection after the filter depth value adjustment, that is, operating normally. If the overcurrent protection still exists after the restart, the filter depth value of the corresponding protection pin is increased again, and this process is repeated to determine whether the purpose of anti-interference can be achieved by adjusting the filter depth value of the protection pin. If the filter depth value of the current protection pin is increased to the preset maximum value and overcurrent protection still exists, it is necessary to further improve the anti-interference capability by adjusting the capacitance value of the protection pin. In this way, the user does not need to repair the air conditioner after a shutdown due to overcurrent protection. Instead, the user can make adjustments on their own, avoiding excessive maintenance of the air conditioner.

[0040] In the embodiment of the present application, the main chips in the air conditioner include an indoor unit main chip and an outdoor unit main chip. Therefore, when adjusting the filter depth value of the protection pin of the main chip, it is necessary to first determine which host chip has experienced overcurrent protection. Based on this, the method of increasing the filter depth value of the protection pin of the main chip in the air conditioner from a preset minimum value in step 21 may further include:

[0041] Step 31, determining whether the main chip where the overcurrent protection occurs is the main chip of the indoor unit of the air conditioner;

[0042] Step 32: When the internal machine main chip is in overcurrent protection, the filter depth value of the protection pin of the internal machine main chip is increased from the preset minimum value.

[0043] Step 33: When the outdoor main chip of the air conditioner has overcurrent protection, the outdoor main chip is notified through the indoor main chip to increase the filter depth value of the protection pin from the preset minimum value.

[0044] In the embodiment of the present application, if the internal main chip encounters overcurrent protection, the internal main chip can directly adjust the filter depth value of the protection pin. If the external main chip encounters overcurrent protection, the filter depth value that needs to be adjusted needs to be transmitted to the external main chip through the internal main chip. It can be seen that in the embodiment of the present application, the protection pin that encounters overcurrent protection can be on the internal main chip or the external main chip, or the protection pins on both the internal main chip and the external main chip can encounter overcurrent protection. Through communication between the internal main chip and the external main chip, the filter depth value of the protection pin of the external main chip can be adjusted in a timely manner to ensure that the anti-interference ability of the air conditioner is improved.

[0045] In an embodiment of the present application, if the current anti-interference requirement can no longer be met by adjusting the filter depth value of the protection pin, the capacitance value of the protection pin can be further increased. Based on this, the method of adjusting the capacitance value of the protection pin of the main chip in the air conditioner involved in the above step 103 can further include:

[0046] Step 41, increasing the capacitance of the protection pin of the main chip in the air conditioner from a preset minimum value, restarting the air conditioner each time the capacitance is increased, until the air conditioner operates normally after restarting; or

[0047] Step 42: until the capacitance of the protection pin of the main chip in the air conditioner increases to a preset maximum value, the air conditioner is still in the shutdown state when it is restarted.

[0048] In the embodiment of the present application, the adjustment logic for the capacitance value of the above-mentioned protection pin is similar to the adjustment logic for the filter depth value, and both are gradually increased based on the preset minimum value. In a specific example, the corresponding capacitance value can be adjusted by a dip switch, that is, the corresponding capacitance value can be determined by the different codes corresponding to the dip switch. Each adjustment of the dip switch corresponds to a code, and the code corresponds to a capacitance value, which is gradually increased from the preset minimum capacitance value. After the air conditioner has overcurrent protection, the anti-interference ability of the air conditioner is gradually improved, avoiding the situation where the air conditioner needs to be repaired as long as the overcurrent protection occurs, that is, avoiding excessive maintenance of the air conditioner, and also improving the user experience during the use of the air conditioner.

[0049] In this embodiment of the present application, since the air conditioner main chip includes an indoor main chip and an outdoor main chip, when adjusting the capacitance value, it is necessary to first determine whether the main chip currently experiencing overcurrent protection is the indoor main chip or the outdoor main chip, or whether both the indoor main chip and the outdoor main chip are experiencing overcurrent protection. Based on this, the method of increasing the capacitance value of the protection pin of the main chip in the air conditioner from a preset minimum value in step 41 above can further include:

[0050] Step 51, determining the main chip that has overcurrent protection through the fault code, wherein the main chip includes the internal main chip and the external main chip;

[0051] Step 52: Determine the corresponding dial code through the corresponding dial switch of the main chip, and increase the capacitance of the protection pin from the preset minimum value in sequence according to the dial code.

[0052] It can be seen that in the embodiment of the present application, the corresponding main chip can be determined by the codes corresponding to different dip switches. In a specific example, taking the code of the dip switch as a 4-bit binary code as an example, the one starting with 0 is the internal main chip, and the one starting with 1 is the external main chip, such as 0000, which represents that the capacitance value of the protection pin of the internal main chip is the preset minimum value; 1000, which represents that the capacitance value of the protection pin of the external main chip is the preset minimum value. Furthermore, 0001 means that the capacitance value of the protection pin of the internal main chip needs to be increased to a secondary minimum value on the basis of the preset minimum value, and 1001 means that the capacitance value of the protection pin of the external main chip needs to be increased to a secondary minimum value on the basis of the preset minimum value. The above binary codes are only for illustration, and the codes of the dip switches can be set according to needs in different application scenarios.

[0053] In the embodiment of the present application, if the air conditioner still shuts down due to overcurrent protection after adjusting the filter depth value and the capacitance value of the protection pin, it indicates that the air conditioner is faulty and requires manual repair. Therefore, the method of the embodiment of the present application may further include:

[0054] Step 61: When the capacitance value of the protection pin of the main chip in the air conditioner increases to a maximum value and the air conditioner is still in a shutdown state when restarting, it is determined that the air conditioner is faulty.

[0055] The present application is explained below in conjunction with the specific implementation of the embodiment of the present application, which provides a control method for improving the anti-interference of air conditioning, such as Figure 2 As shown, the steps of the method include:

[0056] Step 201, remote control startup;

[0057] Step 202, determine whether the air conditioner is operating normally, if not, go to step 203, if yes, go to step 208;

[0058] Step 203, determine whether the air conditioner is in overcurrent protection, if yes, go to step 205, if not, go to step 204;

[0059] Step 204: Perform shutdown protection according to the original logic;

[0060] Step 205: Send a command to the main chip to adjust the filter depth value;

[0061] Step 206: The chip selects different filter depths;

[0062] Step 207: If overcurrent protection still occurs after adjusting the filter depth value, adjust the capacitance value through the DIP switch;

[0063] Step 208, connecting to the circuit;

[0064] Step 209: Run according to settings.

[0065] As can be seen from steps 201 to 209 above, in this specific embodiment, the air conditioner is first remotely powered on. If the air conditioner is operating normally, it will operate normally according to the air conditioner's original control logic. If the air conditioner shuts down due to a protective function, it first determines whether it is an overcurrent protection function. If not, it will shut down according to the original air conditioner control logic, and after-sales service personnel can provide on-site repairs. If it is an overcurrent protection function, the specific overcurrent condition is determined, as different overcurrent protection functions correspond to different pins on the main chip. After determining the type of overcurrent protection function, the first layer of logic is initially executed by default. Data is transmitted to the indoor unit main chip via a remote control key combination, Bluetooth, or Wi-Fi. If the protection function is indoor, the received data can be directly processed. If it is outdoor protection, the indoor unit receives the data and then transmits it to the outdoor unit main chip via indoor-outdoor communication. Each gear position corresponds to a different filter depth value. The indoor-outdoor main chip reads the gear position and stores it in memory. The filter depths of different pins are modified during the next chip initialization upon power-up, thereby improving anti-interference capabilities. The gear positions can be tested sequentially from small to large until a valid gear position is selected, terminating the operation.

[0066] If all gears, that is, the filter depth tests for different pins, are ineffective, the second-level logic is used. Using two DIP switches, the internal and external unit controllers are controlled separately. After distinguishing the internal and external unit faults according to the different fault codes, the corresponding DIP switches are controlled. Each DIP switch corresponds to a different capacitor value, and the switches are connected to the circuit in ascending order until a valid DIP switch is selected. If neither method is effective, it can be determined that the motherboard has an overcurrent fault. After-sales personnel can replace the motherboard and corresponding accessories according to the after-sales process.

[0067] It can be seen that through the above method, the first-level logic repair does not require disassembly of the machine, nor does it require replacement of the internal and external unit mainboards. According to the actual situation of the after-sales technician, different methods can be selected to handle the problem conveniently and quickly. If the first-level logic does not work, there is still the second-level logic. Under the control of dual logic, the after-sales failure rate and maintenance costs are reduced, and the chance of air conditioning repairs due to misprotection, which makes users have no air conditioning and anxiously waiting, is reduced, thereby improving the brand reputation of the air conditioner.

[0068] Therefore, in the embodiment of the present application, several gears are set in advance on the main control chip, corresponding to different filtering depths, which are transmitted to the main chips of the indoor and outdoor units through the remote control combination keys or Bluetooth and WIFI. Because the filtering depth of the chip is limited and cannot be increased indefinitely, if the overcurrent protection is still not solved, the dip switches on the main boards of the indoor and outdoor units can be used. Each gear corresponds to a different capacitor value, which is connected to the circuit in turn through the dip switches to enhance the anti-interference ability of different pins of the chip to solve the problem of false protection of the air conditioner due to the instability of the external power grid.

[0069] Corresponding to the above Figure 1 , the embodiment of the present application also provides an air conditioner anti-interference control device, such as Figure 3 As shown, the device includes:

[0070] The judgment module 302 is used to judge whether the shutdown reason is overcurrent protection when the air conditioner stops;

[0071] The first processing module 304 is configured to adjust the filter depth value of the protection pin of the main chip in the air conditioner when the shutdown reason is overcurrent protection, and restart the air conditioner after the adjustment;

[0072] The second processing module 306 is configured to adjust the capacitance value of the protection pin of the main chip in the air conditioner if the air conditioner still stops due to overcurrent protection after the filter depth value of the protection pin is adjusted to the maximum and the air conditioner is restarted.

[0073] Through the device of the embodiment of the present application, if the current air conditioner is shut down due to overcurrent protection, the filter depth value of the protection pin of the air conditioner main chip can be adjusted, and the air conditioner can be restarted again after the adjustment. If the air conditioner can run normally after adjusting the filter depth value of the protection pin, it means that the anti-interference of the overcurrent protection can be completed by adjusting the filter depth value. If the air conditioner still shuts down due to overcurrent protection after adjusting the filter depth value of the protection pin, the capacitance value of the protection pin of the main chip can be further adjusted to further improve the anti-interference ability of the air conditioner. It can be seen that through the above-mentioned adjustment of the filter depth value of the main chip protection pin and the capacitance value of the main chip protection pin of the embodiment of the present application, the anti-interference ability of the air conditioner is greatly improved on the double-layer anti-interference mechanism, which can further stabilize the operating state of the air conditioner and solve the problem in the related art that the air conditioner is subject to corresponding interference due to grid voltage fluctuations, resulting in false protection of the air conditioner.

[0074] In an optional implementation manner of the embodiment of the present application, the first processing module in the embodiment of the present application may further include: a first processing unit, used to increase the filter depth value of the protection pin of the main chip in the air conditioner from a preset minimum value in sequence, and restart the air conditioner once each time it increases until the air conditioner operates normally after restarting; or, a second processing unit, used to increase the filter depth value of the protection pin of the main chip in the air conditioner to a preset maximum value, and the air conditioner is still in a shutdown state when it is restarted.
