[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0025] In order to solve the problem in the related art that the air conditioner may be disturbed 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, first determine 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 the key protection, the main chip has pins with other functions.

[0028] Step 102, when the shutdown reason is overcurrent protection, adjusting the filter depth value of the protection pin of the main chip in the air conditioner, and restarting the air conditioner again after the adjustment;

[0029] In the embodiment of the present application, different filter depth values ​​correspond to different anti-interference capabilities, and the higher the filter depth value, the stronger the corresponding anti-interference capability. Therefore, when it is determined that the current shutdown reason 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 anti-interference capability. However, the anti-interference capability of the protection pin is limited, that is, if the filter depth value of the protection pin is adjusted to the maximum value, there is still a shutdown caused by overcurrent protection, then 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 is still shut 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 due to overcurrent protection run normally, 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 an 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 this 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 enhance 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 protection pin of the main chip and the capacitance value of the protection pin of the main chip in the embodiment of the present application, the anti-interference ability of the air conditioner is greatly enhanced on top of the double-layer anti-interference mechanism, and the operating state of the air conditioner can be further stabilized, solving the problem in the related technology that the air conditioner is subjected to corresponding interference due to grid voltage fluctuations, resulting in misprotection of the air conditioner.

[0033] In the embodiment of the present application, different types of overcurrent protection are provided in the main chip through different protection pins. Therefore, before adjusting the filter depth value, the type of current overcurrent protection must be determined first, 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 the preset minimum value further increased on the basis of the filter depth value of the current protection pin. By gradually increasing the filter depth value on the basis of the initial filter depth value, the anti-interference ability of the air conditioner can be further improved. Based on this, the method of adjusting the filter depth value of the protection pin of the main chip in the air conditioner involved in step 102 in the embodiment of the present application 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 the preset minimum value in sequence, restarting the air conditioner once each time the value is increased, until the air conditioner runs normally after restarting; or,

[0038] Step 22, increase the filter depth value of the protection pin of the main chip in the air conditioner from a preset minimum value in sequence, restart the air conditioner each time it increases, until the air conditioner runs normally after restarting until the filter depth value of the protection pin of the main chip in the air conditioner increases to a preset maximum value, and the air conditioner is still in a shutdown state when it is restarted.

[0039] Through the above steps 21 and 22, after the 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. Further, on the basis of the current filter depth value, the corresponding filter depth value is gradually increased. In the embodiment of the present application, multiple filter depth values ​​that need to be increased can be set, starting from the preset minimum filter depth value and increasing in sequence. Each time the filter depth value is increased, the air conditioner is restarted to determine whether the current air conditioner does not have overcurrent protection after adjusting the filter depth value, that is, normal operation. If there is still overcurrent protection after restarting, the filter depth value of the corresponding protection pin is increased again, and so on and so forth 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 there is still overcurrent protection, it is necessary to further improve the anti-interference ability by adjusting the capacitance value of the protection pin. In this way, the user does not need to repair the air conditioner after the shutdown due to overcurrent protection occurs. It can be adjusted by itself first to avoid excessive maintenance of the air conditioner.

[0040] In the embodiment of the present application, the main chip in the air conditioner includes an indoor main chip and an outdoor 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 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 the preset minimum value in the above 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 has overcurrent protection, the filter depth value of the protection pin of the internal machine main chip is increased from the preset minimum value in sequence;

[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 in sequence.

[0044] In the embodiment of the present application, if the overcurrent protection occurs in the indoor main chip, the indoor main chip can directly adjust the filter depth value of the protection pin. If the overcurrent protection occurs in the outdoor main chip, the filter depth value that needs to be adjusted needs to be transmitted to the outdoor main chip through the indoor main chip. It can be seen that in the embodiment of the present application, the protection pin where the overcurrent protection occurs can be on the indoor main chip or the outdoor main chip, or the protection keys on both the indoor main chip and the outdoor main chip can have overcurrent protection. Through the communication between the indoor main chip and the outdoor main chip, the filter depth value of the protection pin of the outdoor main chip can be adjusted in time to ensure the improvement of the anti-interference ability of the air conditioner.

[0045] In the embodiment of the present application, if the current anti-interference requirement cannot 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 in sequence, restarting the air conditioner once each time the capacitance is increased, until the air conditioner runs normally after restarting; or,

[0047] Step 42, increasing the capacitance value of the protection pin of the main chip in the air conditioner from a preset minimum value in sequence, restarting the air conditioner each time it increases, until the air conditioner runs normally after restarting until the capacitance value of the protection pin of the main chip in the air conditioner increases to a preset maximum value, and the air conditioner is still in a shutdown state when it is restarted.

[0048] In the embodiment of the present application, the adjustment logic of the capacitance value of the above-mentioned protection pin is similar to the adjustment logic of 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 is repaired as long as the overcurrent protection occurs, that is, avoiding excessive maintenance of the air conditioner, and can also improve the user experience during the use of the air conditioner.

[0049] In the embodiment of the present application, since the main chip of the air conditioner includes an internal main chip and an external main chip, when adjusting the capacitance value, it is necessary to first determine whether the main chip currently experiencing overcurrent protection is the internal main chip or the external main chip, or whether both the internal main chip and the external main chip have experienced 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 the preset minimum value in the above step 41 may further include:

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

[0051] Step 52, determining the corresponding dial code through the dial switch corresponding to the main chip, and increasing the capacitance value 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 code 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 machine main chip, and the one starting with 1 is the external machine main chip, such as 0000, which represents the capacitance value of the protection pin of the internal machine main chip as the preset minimum value; 1000, represents the capacitance value of the protection pin of the external machine main chip as the preset minimum value. Furthermore, 0001 represents that the capacitance value of the protection pin of the internal machine main chip needs to be increased again on the basis of the preset minimum value to the secondary minimum value, and 1001 represents that the capacitance value of the protection pin of the external machine main chip needs to be increased again on the basis of the preset minimum value to the secondary minimum value. The above binary code is only an example, and the code of the dip switch 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 needs manual maintenance. 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, if 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 a specific implementation of an embodiment of the present application. The specific implementation provides a control method for improving the anti-interference of an air conditioner, 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, proceed to step 203, if yes, proceed to step 208;

[0058] Step 203, determine whether the air conditioner is in overcurrent protection, if yes, go to step 205, if no, go to step 204;

[0059] Step 204, performing shutdown protection according to the original logic;

[0060] Step 205, sending 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] It can be seen from the above steps 201 to 209 that in this specific implementation, the remote control is first turned on. If the air conditioner runs normally, it runs normally according to the control logic originally designed for the air conditioner. When the air conditioner is shut down for protection, first determine whether it is overcurrent protection. If it is not overcurrent protection, it will be shut down according to the original air conditioner control logic, and the after-sales personnel can come to repair it. If it is overcurrent protection, determine what kind of overcurrent it is, because different overcurrent protections correspond to different pins of the main chip. After determining the type of overcurrent protection, the first layer of logic is executed by default for the first time, and the data is transmitted to the main chip of the indoor unit through the combination key of the remote control, or Bluetooth and WIFI. If it is indoor protection, the received data can be directly processed. If it is outdoor protection, the indoor unit needs to receive the data and transmit it to the main chip of the outdoor unit through the communication between the indoor and outdoor units. Each gear corresponds to a different filter depth value. The main chip of the indoor and outdoor units reads the gear and stores it in the record. When the chip is initialized next time, the filter depth of different pins is modified to increase the anti-interference ability. The gear can be tested from small to large in sequence until the valid gear is selected and the operation is terminated.

[0066] If all gears, i.e. the filter depth of different pins, have no effect after testing, the second-level logic is used. Through the dip switch method, the internal and external machine controllers are controlled by two dip switches respectively. After distinguishing the internal and external machine faults according to different fault codes, the corresponding dip switch control can be performed. Each dip corresponds to a different capacitor value, and the dip switches are still connected to the circuit in order from small to large until the effective dip is selected and the operation is terminated. If both methods cannot effectively control the protection, it can be judged that the mainboard does have an overcurrent fault, and the after-sales staff can replace the mainboard 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. Different methods can be selected according to the actual situation of the after-sales master, so that after-sales problems can be handled 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 air-conditioning repair caused by incorrect protection is reduced, which reduces the chance of users having no air conditioning and anxiously waiting, thereby improving the brand reputation of the air-conditioning.

[0068] Therefore, in the embodiment of the present application, several gears are set in the main control chip in advance, corresponding to different filtering depths, which are transmitted to the main chips of the internal and external 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 of the internal and external unit mainboards 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, so as to solve the false protection phenomenon 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 comprises:

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

[0071] The first processing module 304 is used 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 again after the adjustment;

[0072] The second processing module 306 is used to adjust the capacitance value of the protection pin of the main chip in the air conditioner when the air conditioner is still shut down 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 main chip of the air conditioner 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 this 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 enhance 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 protection pin of the main chip and the capacitance value of the protection pin of the main chip 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, and the operating state of the air conditioner can be further stabilized, which solves the problem in the related technology that the air conditioner is subjected to corresponding interference due to the voltage fluctuation of the power grid, resulting in the air conditioner being misprotected.
