Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular provides a control method of an air conditioner and an air conditioner. Background Art

[0002] The main function of air conditioners is to adjust the indoor air environment to provide more comfortable living and working conditions. With the widespread use of air conditioners, people's requirements for air conditioners are becoming more and more diverse and humanized.

[0003] In order to avoid damage to the air conditioner caused by continued operation, the existing air conditioner is usually stopped immediately after a malfunction occurs to ensure the safety of the air conditioner. Air conditioner maintenance usually requires professional maintenance personnel. Due to the limited number of maintenance personnel, the air conditioner cannot be repaired in time during the season when the air conditioner is used at a high rate, making the air conditioner unusable during the period of waiting for maintenance, which seriously affects the user experience.

[0004] Accordingly, the art requires a new air conditioner control method and air conditioner to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing air conditioner cannot take into account both safety and user experience after a failure.

[0006] In a first aspect, the present invention provides a method for controlling an air conditioner, the method comprising: after receiving fault information, determining the fault category according to the fault information; if the fault category belongs to a set fault category, controlling the air conditioner to operate with a preset locking parameter value; when the air conditioner operates with the locking parameter value for a time period greater than or equal to a threshold, controlling the air conditioner to shut down.

[0007] When the above technical solution is adopted, after receiving the fault information, the air conditioner is controlled to first determine the fault category. If the fault category belongs to the set fault category, such as the fault of non-core components, or other faults that have little or almost no impact on the safety of the air conditioner, the air conditioner is controlled to run for a period of time with the locked parameter value and then shut down. It can continue to provide basic cooling or heating capacity, so that the user can continue to use the air conditioner before repairing it, ensuring the user experience. At the same time, since it runs at the locked parameter value, it can cause the smallest possible impact on the safety of the air conditioner, and shutting down after running for a period of time avoids damage caused by long-term operation of the air conditioner in a faulty state. In summary, the above control method can make the air conditioner take into account both safety and user experience after a fault occurs.

[0008] In a specific implementation of the control method of the above-mentioned air conditioner, before the step of "controlling the air conditioner to operate with a preset locking parameter value", the control method also includes: obtaining the number of times the air conditioner operates with the locking parameter value as the number of fault operations; determining the duration threshold value based on the number of fault operations; wherein the duration threshold value decreases as the number of fault operations increases.

[0009] When the above technical solution is adopted, since the risk of a fault affecting the safety of the air conditioner increases with the number of times the air conditioner runs at the locked parameter value, the time value for controlling the air conditioner to run at the locked parameter value is reduced as the number of operations increases, which can further ensure the safety of the air conditioner while continuing to provide basic cooling or heating capacity.

[0010] In a specific implementation of the control method of the above-mentioned air conditioner, before the step of "obtaining the number of times the air conditioner runs with the locked parameter value", the control method also includes: obtaining the number of times the fault information is received as the number of fault triggering times; the step of "obtaining the number of times the air conditioner runs with the locked parameter value" further includes: if the number of fault triggering times is greater than or equal to a first set number, then obtaining the number of times the air conditioner runs with the locked parameter value; wherein the first set number is greater than or equal to 2.

[0011] When adopting the above technical solution, the reliability is low because there is a possibility of accidental or external interference in receiving fault information once. Therefore, when fault information is received multiple times, controlling the air conditioner to operate with locked parameter values ​​can improve reliability and avoid affecting the normal use of the air conditioner.

[0012] In a specific implementation of the above-mentioned air conditioner control method, the step of "controlling the air conditioner to operate with a preset locking parameter value" further includes: if the number of fault operations is less than or equal to a second set number of times, controlling the air conditioner to operate with a preset locking parameter value.

[0013] When adopting the above technical solution, if the number of faulty operations is less than or equal to the second set number, the risk of the faulty operation affecting the safety of the air conditioner is low. At this time, controlling the air conditioner to operate with a locked parameter value can ensure the safety of the air conditioner.

[0014] In a specific implementation of the above-mentioned air conditioner control method, after the step of "obtaining the number of times the air conditioner runs with the locked parameter value as the number of faulty operations", the control method also includes: if the number of faulty operations is greater than the second set number, controlling the air conditioner to shut down.

[0015] When adopting the above technical solution, if the number of faulty operations is greater than the second set number, the risk of the faulty operation affecting the safety of the air conditioner is high. In order to avoid damage caused by the air conditioner running in a faulty state, the air conditioner is controlled to shut down to ensure the safety of the air conditioner.

[0016] In a specific implementation of the air conditioner control method, the step of "determining the duration threshold according to the number of fault operations" further includes: the duration threshold T n =Tn×t; wherein n is the number of faulty operations, T is a preset initial duration value, and t is a preset duration change value; and / or after the step of "controlling the air conditioner to shut down", the control method further includes: updating the number of faulty operations to add 1.

[0017] When the above technical solution is adopted, through T n =Tn×t can calculate the duration threshold according to the number of fault operations, and can reduce the duration threshold as the number of fault operations increases. After the air conditioner operates with the locked parameter value, the number of fault operations is increased by 1, so as to accurately record the number of fault operations for subsequent use.

[0018] In a specific implementation of the above air conditioner control method, before the step of "obtaining the number of times the air conditioner runs with the locked parameter value", the control method further includes: controlling the power-on relay of the air conditioner to restart.

[0019] In the case of adopting the above technical solution, before obtaining the number of times the air conditioner runs with the locked parameter value, controlling the power-on relay of the air conditioner to restart can clear the number of fault triggering times stored in the air conditioner.

[0020] In a specific implementation of the control method of the above-mentioned air conditioner, after the step of "controlling the air conditioner to shut down", the control method also includes: issuing a reminder message to remind the user to repair the air conditioner; and / or the step of "controlling the air conditioner to operate with a preset locking parameter value" further includes: controlling the compressor of the air conditioner to operate with a preset locking frequency value; controlling the fan of the air conditioner to operate with a preset locking speed value; controlling the air guide plate of the air conditioner to operate with a preset locking angle value.

[0021] When the above technical solution is adopted, the user can be reminded that the air conditioner needs to be repaired by issuing a reminder message, so that the fault problem can be eliminated as soon as possible to ensure the normal use of the air conditioner. The compressor, fan and air guide plate are controlled to operate with corresponding locking parameters to ensure the safety of the air conditioner.

[0022] In a specific implementation of the above-mentioned air conditioner control method, the set fault category includes at least one of an ambient temperature sensor fault, a coil sensor fault, an exhaust gas sensor fault, and a high-frequency current excessive shutdown fault.

[0023] When the above technical solution is adopted, the above fault categories are all failures of non-core components, which have little or almost no impact on the safety of the air conditioner.

[0024] In a second aspect, the present invention further provides an air conditioner, comprising: a processor; a memory, wherein the memory is suitable for storing a plurality of program codes, wherein the program codes are suitable for being loaded and run by the processor to execute a control method of the air conditioner.

[0025] Compared with the prior art, the beneficial effect of the air conditioner control method provided by the present invention is: by controlling the air conditioner to first determine the fault category after receiving the fault information, if the fault category belongs to the set fault category, such as the fault of non-core components, or other faults with little or almost no impact on the safety of the air conditioner, the air conditioner is controlled to run for a period of time with a locked parameter value and then shut down, so that the basic cooling or heating capacity can continue to be provided, so that the user can continue to use the air conditioner before repairing it, ensuring the user experience, and at the same time, because it runs with the locked parameter value, it can cause the smallest possible impact on the safety of the air conditioner, and shutting down after running for a period of time avoids damage caused by the air conditioner running for a long time in a faulty state; in summary, the above-mentioned control method can make the air conditioner take into account both safety and user experience after a fault occurs.

[0031] In addition, it should be noted that in the description of the present invention, although the various steps of the control method of the present invention are described in this application in a specific order, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in a different order.

[0032] Based on the problem pointed out in the background technology that the air conditioner in the prior art cannot take into account both safety and user experience after a fault occurs, the present invention aims to control the air conditioner to first determine the fault category after receiving the fault information. If the fault category belongs to the set fault category, such as the fault of non-core components, or other faults that have little or almost no impact on the safety of the air conditioner, the air conditioner is controlled to run for a period of time with a locked parameter value and then shut down, so that the basic cooling or heating capacity can continue to be provided, so that the user can continue to use the air conditioner before repairing it, thereby ensuring the user experience. At the same time, since it runs with the locked parameter value, it can cause the smallest possible impact on the safety of the air conditioner, and shutting down after running for a period of time avoids damage caused by the air conditioner running for a long time in a faulty state. In summary, the above-mentioned control method can make the air conditioner take into account both safety and user experience after a fault occurs.

[0033] The air conditioner of the present invention includes a processor and a memory, the memory is suitable for storing multiple program codes, and the program codes are suitable for being loaded and run by the processor to execute the detection method of the air conditioner. The processor can be a central processing unit, or other general-purpose processors, digital signal processors, application-specific integrated circuits, field programmable gate arrays or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or any conventional processor, etc. The memory can be an internal storage unit of the air conditioner, such as a hard disk or memory, etc.; the memory can also be an external storage device of the air conditioner, for example, a plug-in hard disk, a smart memory card, a secure digital card, a flash memory card, etc. equipped on the air conditioner; the memory can also include both the internal storage unit and the external storage unit of the air conditioner. The air conditioner can include multiple memories and multiple processors, each processor performs different steps respectively, and the multiple processors can be processors deployed on the same device or processors deployed on different devices. For example, the multiple processors can be processors on the air conditioner and processors on the cloud server respectively.

[0034] See first Figure 1 , which shows the main steps of the control method of the air conditioner of the present invention, such as Figure 1 As shown, the control method in this embodiment mainly includes the following steps S101 to S103:

[0035] Step S101: after receiving the fault information, determine the fault type according to the fault information.

[0036] Among them, fault information refers to the fault record automatically generated by the air conditioner after a fault occurs, which may include at least one of the fault code, status information of the faulty component, and detection information of the faulty sensor. There are preset corresponding rules between the fault category and the fault information. The air conditioner can determine the corresponding fault category based on the fault information and its corresponding rules.

[0037] Step S102: If the fault category belongs to the set fault category, the air conditioner is controlled to operate with a preset locking parameter value.

[0038] Among them, the set fault category may include at least one of the ambient temperature sensor fault, coil sensor fault, exhaust sensor fault, and high-frequency current over-high shutdown fault. It may also include faults of other non-core components or other faults that have little or almost no impact on the safety of the air conditioner. It is not specifically limited here, and those skilled in the art can adjust it as needed. The locking parameter value may include the locking frequency value of the compressor, the locking speed value of the fan, the locking angle of the air guide plate, and other parameters. It is not specifically limited here. As long as the air conditioner is running at the locking parameter value, it can provide basic cooling or heating capacity and cause the smallest possible impact on the safety of the air conditioner. Exemplarily, the locking frequency value can be set within the range of 30Hz to 50Hz, such as 30Hz or 45Hz; the wind speed can be set within the range of 600rpm to 900rpm, such as 600rpm or 900rpm.

[0039] Step S103: When the air conditioner runs with the locked parameter value for a time period greater than or equal to a threshold, the air conditioner is controlled to shut down.

[0040] The duration threshold may be a preset fixed value, or may be a plurality of values ​​preset according to different fault categories, or may be a value that changes with the number of times the air conditioner runs with the locked parameter value.

[0041] Through the control method of steps S101 to S103 above, after receiving the fault information, the fault category is first determined. If the fault category belongs to the set fault category, such as a fault of a non-core component, or other faults that have little or almost no impact on the safety of the air conditioner, the air conditioner is controlled to run for a period of time with a locked parameter value and then shut down. The air conditioner can continue to provide basic cooling or heating capacity, so that the user can continue to use it before the air conditioner is repaired, thereby ensuring the user experience. At the same time, since it runs at a locked parameter value, it can cause as little impact on the safety of the air conditioner as possible, and shutting down after running for a period of time avoids damage caused by long-term operation of the air conditioner in a faulty state. In summary, through the above control method, the air conditioner can take into account both safety and user experience after a fault occurs.

[0042] See below Figure 2 , which shows an implementation of the control method of the air conditioner of the present invention, which specifically includes the following steps:

[0043] Step S201: after receiving the fault information, determine the fault type according to the fault information.

[0044] Step S202: Determine whether the fault category belongs to the set fault category. If the determination result is yes, execute step S203; if the determination result is no, execute step S201.

[0045] Step S203: Obtain the number of times the fault information is received as the number of times the fault is triggered.

[0046] Step S204: Determine whether the fault triggering times are greater than or equal to the first set times. If the determination result is yes, execute step S205; if the determination result is no, execute step S201.

[0047] The first set number of times is greater than or equal to 2. Since a single receipt of fault information is accidental or subject to external interference, the reliability is low. Therefore, when fault information is received multiple times, the air conditioner is controlled to run with a locked parameter value, which can improve reliability and avoid affecting the normal use of the air conditioner. The value of the first set number of times can be a fixed value, or different values ​​can be set according to the fault type. For example, the first set number of times can be set to 3 times.

[0048] It should be noted that the order of step S202 to step S204 is not restrictive. Step S203 and step S204 can also be executed first. If the judgment result of step S204 is yes, step S202 is executed. If the judgment result of step S202 is yes, step S205 is executed. Technical personnel in this field can adjust it as needed.

[0049] Step S205: Control the power-on relay of the air conditioner to restart.

[0050] The power-on relay that controls the air conditioner restarts can clear the fault trigger times stored in the air conditioner. After the power-on relay restarts, the air conditioner enters the fault operation mode.

[0051] Step S206: Obtain the number of times the air conditioner operates with the locked parameter value as the number of fault operations.

[0052] Step S207: Determine whether the number of faulty operations is less than or equal to a second set number of times. If the determination result is yes, execute step S208; if the determination result is no, execute step S209.

[0053] When the number of faulty operations is less than or equal to the second set number of times, the risk of the faulty operation affecting the safety of the air conditioner is low. At this time, the air conditioner is controlled to operate with the locked parameter value to ensure the safety of the air conditioner. The value of the second set number of times can be a fixed value or different values ​​can be set according to the fault type. For example, the second set number of times can be set to 5 times.

[0054] Step S208: Determine the duration threshold according to the number of faulty operations. After step S208, execute step S210.

[0055] Among them, the duration threshold decreases with the increase of the number of fault operations. As the risk of the fault affecting the safety of the air conditioner increases with the increase of the number of times the air conditioner runs with the locked parameter value, the duration value for controlling the air conditioner to run with the locked parameter value decreases with the increase of the number of operations. This can further ensure the safety of the air conditioner while continuing to provide basic cooling or heating capacity.

[0056] Specifically, the duration threshold can be determined based on the number of fault operations by using the following formula: n =Tn×t; where T n is the duration threshold, n is the number of fault operations, T is the preset initial duration value, and t is the preset duration change value. The T value can be a relatively fixed value, or different values ​​can be set according to the fault type. For example, the T value can be set in the range of 1 hour to 5 hours, such as 1 hour or 5 hours; the t value can be a relatively fixed value, or different values ​​can be set according to the fault type. For example, the t value can be set in the range of 0.1 hour to 0.8 hours, such as 0.1 hour or 0.8 hour; n is a non-negative integer, such as 0 or 3; the present invention does not specifically limit the above values, and those skilled in the art can adjust them as needed.

[0057] It should be noted that although this embodiment describes that whether to control the air conditioner to operate with a locked parameter value is determined by the number of fault operation times, this is not restrictive. After determining the duration threshold, it is also possible to determine whether to control the air conditioner to operate with a locked parameter value based on the size of the duration threshold; exemplarily, if the duration threshold is greater than or equal to 0.5 hours, the air conditioner is controlled to operate with a preset locked parameter value, that is, step S210 is executed; if the duration threshold is less than 0.5 hours, the air conditioner is controlled to stop, that is, step S209 is executed.

[0058] Step S209: Control the air conditioner to stop.

[0059] If the number of faulty operations is greater than the second set number, the risk of the faulty operation affecting the safety of the air conditioner is high. In order to avoid damage caused by the air conditioner running in a faulty state, the air conditioner is controlled to shut down to ensure the safety of the air conditioner. It should be noted that after the air conditioner is controlled to shut down, the air conditioner can also be controlled to enter a forced maintenance state, which may include not responding to a power-on instruction, issuing a reminder message, etc. After step S209, the air conditioner waits for maintenance and confirms that the fault has been eliminated, and then resumes normal operation, and step S201 is executed at the same time.

[0060] Step S210: Control the air conditioner to operate with a preset locking parameter value.

[0061] Step S211: Determine whether the duration of the air conditioner running at the locked parameter value is greater than or equal to the duration threshold. If the determination result is yes, execute step S212; if the determination result is no, execute step S210.

[0062] Step S212: Control the air conditioner to stop.

[0063] Step S213: Update the fault operation times and add 1 to it.

[0064] After the air conditioner is running with the locked parameter value, the number of fault operations is increased by 1 so that the number of fault operations can be accurately recorded for subsequent use.

[0065] Step S214: Sending a reminder message. After step S214, execute step S201.

[0066] By sending out reminder information, the user can be reminded that the air conditioner needs to be repaired so that the fault problem can be eliminated as soon as possible to ensure the normal use of the air conditioner. The form of the reminder information may include but is not limited to voice type information, text type information, light type information, etc.; the subject that sends out the reminder information may include but is not limited to terminal devices such as air conditioners and mobile phones, etc.; the specific reminder method can be a combination of any of the above reminder forms and reminder subjects, as long as it can have the effect of reminding the user. Those skilled in the art can choose according to the specific needs of the actual application, and no specific limitation is made here. Among them, voice type information can send reminder information to the user in the form of voice broadcast, or remind the user by means of a buzzer prompt tone; text type information can send reminder information to the user by popping up a floating window or scrolling playback; light type information can be a light mode that is lit for a long time or intermittently lit. The settings of the reminder methods described above are only for exemplary explanations, and can be selected according to actual needs in actual applications.

[0067] It should be noted that the order of step S213 and step S214 is not restrictive, and those skilled in the art can adjust it as needed.

[0068] It should be noted that the above-mentioned embodiments are only used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above-mentioned embodiments so that the present invention can be applied to more specific application scenarios.

[0069] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle 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 these changes or substitutions will fall within the protection scope of the present invention.
