Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for self-cleaning an air conditioner, an air conditioner, and a storage medium. Background Technology

[0002] Air conditioners are devices that can cool or heat indoor spaces. Over time, dust accumulates on the indoor unit of an air conditioner. Once the dust reaches a certain level, it can breed a large number of bacteria. In particular, when indoor air flows through the indoor unit, it carries a lot of dust and bacteria. Therefore, it is necessary to clean the air conditioner in a timely manner.

[0003] The relevant technology controls the operation of the indoor unit so that the evaporator first frosts and then defrosts, using the defrosting process to clean the evaporator.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] When using related technologies for self-cleaning of air conditioners, during the defrosting stage, the heat exchanger is exposed to the air, resulting in a significant loss of cooling capacity. This prevents the heat exchanger from maintaining a low temperature and thus prevents timely frost formation. The only solution is to increase the operating frequency of the compressor to keep the heat exchanger at a low temperature, thereby forming more frost, which leads to higher energy consumption. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a method and apparatus for self-cleaning an air conditioner, an air conditioner, and a storage medium to avoid the problem of large-scale loss of cooling capacity during the frost stage of the air conditioner's self-cleaning process, so that the air conditioner does not need to run the compressor at a high operating frequency, thereby improving the energy utilization rate of the air conditioner and reducing the energy consumption of the air conditioner's self-cleaning operation.

[0008] In some embodiments, the air conditioner includes a heat exchanger with front and rear covers, the covers forming a receiving cavity for accommodating the heat exchanger when closed; the method includes: controlling the covers to close for frosting in response to a self-cleaning control command; and controlling the covers to open for defrosting when sufficient frost has formed on the heat exchanger.

[0009] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to execute the above-described method for self-cleaning an air conditioner when executing the program instructions.

[0010] In some embodiments, the air conditioner includes: a drain pipe for conveying condensate and a heat exchanger with front and rear covers, the covers forming a receiving cavity for accommodating the heat exchanger when closed; and the aforementioned device for self-cleaning the air conditioner.

[0011] In some embodiments, the storage medium stores program instructions that, when executed, perform the aforementioned method for self-cleaning an air conditioner.

[0012] The method, apparatus, air conditioner, and storage medium for self-cleaning of air conditioners provided in this disclosure can achieve the following technical effects:

[0013] In response to the self-cleaning control command, the cover is closed to initiate frosting, and when sufficient frost has formed on the heat exchanger, the cover is opened to defrost. During the air conditioner's self-cleaning process, closing the cover during the frosting stage creates a cavity that houses the heat exchanger, reducing cooling loss and ensuring timely frosting. This avoids significant cooling loss during the frosting stage, reducing the need for the air conditioner to operate at a higher compressor frequency, improving energy efficiency, and lowering energy consumption during self-cleaning operation.

[0028] In this embodiment of the disclosure, smart home appliances refer to home appliances formed by introducing microprocessors, sensor technology and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0029] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connectivity.

[0030] This disclosure provides an air conditioner including a drain pipe for conveying condensate and a heat exchanger with front and rear covers. When the covers are closed, they form a cavity to accommodate the heat exchanger. The drain pipe can convey the condensate outdoors or to other structures for reuse, such as for filtering to clean the chassis or for cleaning the filter screen.

[0031] Combination Figure 1 As shown, this disclosure provides a method for self-cleaning an air conditioner, comprising:

[0032] S01, the air conditioner responds to the self-cleaning control command by controlling the cover to close for frosting.

[0033] S02, when there is sufficient frost on the heat exchanger of the air conditioner, the control cover is opened to defrost.

[0034] The volume of the receiving cavity formed by the closed cover can be adjusted, specifically determined by the compressor's operating frequency during self-cleaning. For example, the air conditioner can determine the target volume of the receiving cavity corresponding to the compressor's operating frequency based on a preset correspondence; the air conditioner controls the closure of the cover to form the receiving cavity of the target volume. Specifically, multiple corresponding snap-fit ​​mechanisms can be set in the front or rear cover, connecting the slots at different positions via snap-fits to adjust the volume of the receiving cavity, thus adapting to the cooling capacity requirements of heat exchanger frosting under different environmental parameters.

[0035] The self-cleaning method for air conditioners provided in this disclosure, in response to a self-cleaning control command, controls the cover to close for frosting, and controls the cover to open for defrosting when sufficient frost has formed on the heat exchanger. During the self-cleaning process, closing the cover during the frosting stage to form a cavity housing the heat exchanger reduces cooling loss and allows for timely frosting of the heat exchanger. This avoids significant cooling loss during the frosting stage, reducing the need for the air conditioner to operate at a higher compressor frequency, improving energy efficiency, and lowering energy consumption during self-cleaning operation.

[0036] Combination Figure 2 As shown, this disclosure provides a method for self-cleaning an air conditioner, comprising:

[0037] S01, the air conditioner responds to the self-cleaning control command by controlling the cover to close for frosting.

[0038] S21, the air conditioner detects the current temperature of the heat exchanger.

[0039] S22, if the current temperature of the heat exchanger is lower than the temperature threshold and this condition persists for a first duration, the air conditioner determines that the amount of frost on the heat exchanger is sufficient.

[0040] S02, when there is sufficient frost on the heat exchanger of the air conditioner, the control cover is opened to defrost.

[0041] The self-cleaning method for air conditioners provided in this embodiment detects the current temperature of the heat exchanger. If the current temperature of the heat exchanger is below a temperature threshold and remains below it for a first duration, it is determined that the amount of frost on the heat exchanger is sufficient. When the temperature of the heat exchanger is below the temperature threshold, it indicates that the temperature has reached the most efficient frosting temperature under the current operating conditions, satisfying the frosting requirements without causing the heat exchanger to freeze. Maintaining this temperature for the first duration confirms that the current amount of frost on the heat exchanger is sufficiently high.

[0042] Optionally, after detecting the current temperature of the heat exchanger, the air conditioner further includes: when the current temperature of the heat exchanger is less than the freezing temperature threshold, controlling the air conditioner to reduce the operating frequency of the compressor.

[0043] In this way, if the current temperature of the heat exchanger is lower than the freezing temperature threshold, the temperature of the heat exchanger will be too low and freezing will occur, increasing the load during the defrosting stage. In order to reduce the system load during the defrosting stage, the operating frequency of the compressor is reduced, the amount of cold air in the cavity is reduced, the temperature of the heat exchanger is increased, and the freezing phenomenon of the heat exchanger is avoided.

[0044] Optionally, the air conditioner determines the temperature threshold and the first duration according to the following method: the air conditioner obtains the current environmental parameters of the area where the heat exchanger is located and the frosting area of ​​the heat exchanger; the air conditioner determines the frosting temperature and frosting duration corresponding to the current environmental parameters and the frosting area according to a first relationship; the air conditioner determines the frosting temperature and frosting duration as the temperature threshold and the first duration, respectively; wherein, the temperature threshold is greater than the freezing temperature of the heat exchanger.

[0045] In this way, the air conditioner obtains the current environmental parameters of the area where the heat exchanger is located and the frosting area of ​​the heat exchanger, and determines the frosting temperature and frosting duration corresponding to the current environmental parameters and frosting area according to the first relationship. Since the heat exchanger is located in the containment cavity, the environmental parameters affect the frosting temperature and frosting rate of the heat exchanger. Therefore, the frosting temperature and frosting rate under the current environment can be determined based on the current environmental parameters. On this basis, the frosting area of ​​the air conditioner determines the frosting duration. Therefore, the frosting duration of the heat exchanger under the current operating conditions can be determined according to the required frosting area of ​​the heat exchanger. Finally, the frosting temperature and frosting duration are determined as the temperature threshold and the first duration, respectively.

[0046] Optionally, the air conditioner determines the temperature threshold and the first duration according to the following method, and further includes: the air conditioner corrects the first duration based on the volume of the accommodating cavity.

[0047] In this way, the air conditioner corrects the initial duration based on the volume of the receiving cavity, making the frosting time of the heat exchanger more accurate. This avoids excessively long frosting times that affect frosting efficiency, or excessively short frosting times that result in insufficient frosting. Since the receiving cavity reduces the loss of cooling capacity, its volume is closely related to frosting efficiency. Correcting the initial duration based on the volume of the receiving cavity takes into account the relationship between the volume of the receiving cavity and cooling capacity loss, making the initial duration more accurate and improving the frosting efficiency of the heat exchanger. For example, the air conditioner can determine the corrected duration corresponding to the current volume of the receiving cavity based on a third relationship; the first duration is then corrected using this corrected duration, and the corrected first duration is used as the new first duration to control the frosting of the heat exchanger.

[0048] Combination Figure 3 As shown, this disclosure provides a method for self-cleaning an air conditioner, comprising:

[0049] S31, the air conditioner responds to the self-cleaning control command and determines whether the amount of condensate on the heat exchanger is sufficient based on the current flow rate of condensate in the drain pipe.

[0050] S32, when the air conditioner has sufficient condensate on the heat exchanger, confirm that the control cover is closed.

[0051] S33, the air conditioner control cover is closed for frosting.

[0052] S02, when there is sufficient frost on the heat exchanger of the air conditioner, the control cover is opened to defrost.

[0053] The self-cleaning method for air conditioners provided in this embodiment determines whether the amount of condensate on the heat exchanger is sufficient based on the current flow rate of condensate in the drain pipe, and closes the control cover when the amount of condensate on the heat exchanger is sufficient. Since the condensate on the heat exchanger flows to the drain pipe, the flow rate of condensate at the drain pipe can monitor the condensate generation on the heat exchanger, thereby accurately determining when to enter the defrosting stage and improving the efficiency of the air conditioner's self-cleaning.

[0054] Combination Figure 4 As shown, this disclosure provides a method for self-cleaning an air conditioner, comprising:

[0055] S41, the air conditioner responds to the self-cleaning control command and obtains the current flow rate in real time.

[0056] S42, if the air conditioner determines that the amount of condensate on the heat exchanger is sufficient when the current flow rate is greater than the flow rate threshold and continues for a second time.

[0057] S32, when the air conditioner has sufficient condensate on the heat exchanger, confirm that the control cover is closed.

[0058] S33, the air conditioner control cover is closed for frosting.

[0059] S02, when there is sufficient frost on the heat exchanger of the air conditioner, the control cover is opened to defrost.

[0060] Using the self-cleaning method for air conditioners provided in this embodiment, the air conditioner acquires the current flow rate of the drain pipe in real time. If the current flow rate is greater than a flow threshold and remains so for a second duration, the air conditioner determines that the condensate volume on the heat exchanger is sufficient. A current flow rate greater than the flow threshold indicates a large condensate flow rate in the drain pipe. The second duration indicates a uniform condensate flow rate in the drain pipe, rather than a sudden increase in condensate volume over a short period. Therefore, the air conditioner can determine that the uniform condensate flow rate in the drain pipe indicates sufficient water on the heat exchanger for defrosting.

[0061] Optionally, the air conditioner determines the flow threshold by means of the following method: the air conditioner obtains the condensate rate of the heat exchanger; the air conditioner determines the flow threshold based on the change in the condensate rate.

[0062] The condensation rate can be obtained by looking up a table based on the data recorded during the performance test of the air conditioner. For example, the condensation rate corresponding to the compressor's operating frequency can be determined based on the compressor's operating frequency.

[0063] In this way, the air conditioner obtains the condensation rate of the heat exchanger and determines the flow threshold based on the changes in the condensation rate. By obtaining the condensation rate of the heat exchanger in real time, the generation of condensate on the heat exchanger can be obtained, thereby predicting the flow threshold at the drain pipe when there is sufficient condensate.

[0064] Optionally, combined Figure 5 As shown, the air conditioner determines the flow threshold based on changes in the condensation rate, including:

[0065] S51, when the change in condensation rate is less than the amplitude threshold, the air conditioner determines the standard flow rate corresponding to the current condensation rate according to the second relationship.

[0066] S52, the air conditioner determines the standard flow rate as the flow threshold.

[0067] In this way, when the change in condensation rate is less than the threshold value, the air conditioner determines the standard flow rate corresponding to the current condensation rate based on the second relationship, and sets this standard flow rate as the flow rate threshold. When the change in condensation rate is small, it indicates that the amount of condensate produced on the heat exchanger is relatively stable. Therefore, based on the current condensation rate, the standard flow rate of the drain pipe can be determined to provide sufficient water for frost formation on the heat exchanger, thereby improving the accuracy of the cover plate closing timing and increasing the self-cleaning efficiency.

Optionally, the apparatus may further include a communication interface 102 and a bus 103. The processor 100, communication interface 102, and memory 101 can communicate with each other via the bus 103. The communication interface 102 can be used for information transmission.
