Description

Technical Field

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

[0002] Currently, air conditioners on the market will automatically shut down if the indoor temperature reaches the user's set temperature during the cooling process.

[0003] When an air conditioner is used in a small space, during cooling operation, the compressor and motor stop when the indoor temperature sensor detects that the ambient temperature is lower than the set temperature. However, because the ambient temperature sensor is affected by the low-temperature radiation from the evaporator, the temperature it senses is also lower. Even when the detected indoor ambient temperature is lower than the set temperature, both the compressor and the indoor fan stop prematurely. This results in the actual indoor temperature still being higher than the set temperature, leading to an inability to achieve a precise and comfortable cooling effect, thus affecting the user experience.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to at least a certain extent solve the problem that existing air conditioners cannot accurately reach the temperature to start and stop, resulting in a poor user experience.

[0006] In a first aspect, the present invention provides a control method for an air conditioner, the air conditioner including an indoor unit and a temperature detection component disposed on the indoor unit, the temperature detection component being used to detect the indoor ambient temperature where the indoor unit is located, and the control method including: acquiring a preset temperature T0 set by a user; acquiring an indoor ambient temperature T1 detected by the temperature detection component; and selectively adjusting the operating states of the compressor and the indoor fan of the air conditioner according to the preset temperature T0 and the indoor ambient temperature T1.

[0007] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the compressor and indoor fan of the air conditioner according to the preset temperature T0 and the indoor ambient temperature T1" specifically includes: calculating the difference Δ = T0 - T1; comparing the difference Δ with the first preset value A1 and the second preset value A2 respectively; and selectively adjusting the operating status of the compressor and indoor fan of the air conditioner according to the comparison result; wherein, A1 > A2 ≥ 0.

[0008] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan according to the comparison result" specifically includes: if Δ > A1, then the compressor stops running and the indoor fan stops running.

[0009] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan according to the comparison result" specifically includes: if A2≤△≤A1, then the compressor stops running and the indoor fan continues to run.

[0010] In a preferred embodiment of the above control method, after the compressor stops running, the control method further includes: acquiring the running time of the indoor fan after the compressor stops running; when the running time reaches a preset duration, acquiring the current indoor ambient temperature T2 detected by the temperature detection component; and selectively adjusting the operating states of the compressor and the indoor fan according to the current ambient temperature T2 and the preset temperature T0.

[0011] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating state of the compressor and the indoor fan according to the current ambient temperature T2 and the preset temperature T0" specifically includes: determining whether the current ambient temperature T2 is greater than the preset temperature T0 according to the current ambient temperature T2 and the preset temperature T0; and selectively adjusting the operating state of the compressor and the indoor fan according to the determination result.

[0012] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the compressor and the indoor fan according to the judgment result" specifically includes: if the judgment result is "no", then the compressor is kept off and the indoor fan is stopped.

[0013] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the compressor and the indoor fan according to the judgment result" specifically includes: if the judgment result is "yes", then start the compressor and make the indoor fan continue to run.

[0014] In the preferred embodiment of the above control method, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan according to the comparison result" specifically includes: if Δ < A2, then the compressor continues to run and the indoor fan continues to run.

[0015] In a second aspect, the present invention provides an air conditioner including a controller configured to perform the control method described above.

[0016] When the above technical solution is adopted, the air conditioner is in cooling mode. By acquiring the indoor ambient temperature and the user-set preset temperature, the operating status of the air conditioner's compressor and indoor fan is selectively adjusted according to the indoor ambient temperature and the preset temperature. This enables individual control of the compressor and indoor fan, and the indoor ambient temperature is flexibly adjusted by the operating status of the compressor and indoor fan. This facilitates precise control of the air conditioner to stop when the temperature is reached, thus improving the user experience.

[0017] Furthermore, compared to directly comparing the indoor ambient temperature T1 with the preset temperature T0 and selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison result, this method first calculates the difference between the preset temperature T0 and the indoor ambient temperature T1, then compares this difference with a first preset value and a second preset value, and selectively adjusts the operating status of the air conditioner's compressor and indoor fan based on the comparison result. On the one hand, this avoids misjudgments caused by detection errors of the temperature detection components, thereby improving the accuracy of the air conditioner's temperature-reaching start-up and shutdown. On the other hand, it avoids frequent adjustments of the compressor and indoor fan, while shortening the air conditioner's temperature-reaching control time, thus enabling the indoor ambient temperature to reach the user's preset temperature as quickly as possible, further enhancing the user experience.

[0018] Furthermore, when △>A1, it indicates that the indoor ambient temperature is lower than the preset temperature, and the difference between the indoor ambient temperature and the preset temperature is relatively large. This means that the indoor ambient temperature is relatively low. By promptly shutting off the compressor, the refrigerant can be prevented from continuing to circulate and causing the indoor temperature to drop further. By promptly shutting off the indoor fan, the indoor fan can be prevented from blowing the cold air from the indoor heat exchanger into the room, thereby preventing the indoor ambient temperature from dropping further and improving the user experience.

[0019] Furthermore, when A2≤△≤A1, it indicates that the indoor ambient temperature is lower than the preset temperature, and the difference between the preset temperature and the indoor ambient temperature is between the first preset value A1 and the second preset value A2. In this case, the compressor stops running while the indoor fan continues to run. On the one hand, this avoids the refrigerant from continuing to circulate and causing a further significant drop in the indoor ambient temperature. On the other hand, by keeping the indoor fan running, the residual cooling energy on the indoor heat exchanger continues to be blown into the room. This not only makes full use of the residual cooling energy on the indoor heat exchanger but also further reduces the indoor ambient temperature so that the actual indoor ambient temperature reaches the preset temperature. This eliminates the influence of the low-temperature radiation from the indoor heat exchanger on the temperature detection component, which causes a deviation in the detected indoor ambient temperature. This helps to ensure that the actual indoor ambient temperature reaches the preset temperature, making the indoor ambient temperature more comfortable and further improving the user experience.

[0020] Furthermore, after the compressor stops running, the operating time of the indoor fan after the compressor stops running is obtained; when the operating time reaches the preset time, the current indoor ambient temperature detected by the temperature detection component is obtained; based on the current ambient temperature and the preset temperature, the operating status of the compressor and the indoor fan is selectively adjusted. After the compressor stops running, the indoor fan blows away the residual cold air on the outdoor heat exchanger before the temperature detection component detects the current indoor ambient temperature. This eliminates the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component, making the value detected by the temperature detection component closer to the actual indoor ambient temperature at this time. Selectively adjusting the operating status of the compressor and the indoor fan based on the detected current ambient temperature and the preset temperature can make the indoor ambient temperature closer to the user's preset temperature, thereby making the indoor ambient temperature more comfortable and further improving the user experience.

[0021] Furthermore, after the compressor stops running and the indoor fan has been running continuously for a preset time, the indoor fan blows away the cold air from the indoor heat exchanger, eliminating the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component. The current indoor ambient temperature is then detected again and is closer to the actual indoor ambient temperature. If the judgment result is "no", it means that the current indoor ambient temperature is less than or equal to the preset temperature, which means that the indoor ambient temperature has reached the preset temperature. The compressor is then kept off and the indoor fan stops running, enabling the air conditioner to achieve temperature-reaching shutdown and ensuring that the indoor ambient temperature reaches the user-set preset temperature, providing the user with a more comfortable environment and further improving the user experience.

[0022] Furthermore, after the compressor stops running and the indoor fan continues to run for a preset time, i.e., the indoor fan blows away the cold air from the indoor heat exchanger, eliminating the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component, the current indoor ambient temperature is detected again and is closer to the actual indoor ambient temperature. If the judgment result is "yes", it means that the current ambient temperature is still higher than the preset temperature, that is, the indoor ambient temperature has not yet dropped to the preset temperature. It is necessary to restart the compressor and keep the indoor fan running to continue cooling the indoor environment so that the indoor ambient temperature reaches the preset temperature.

[0023] Furthermore, the air conditioner provided by the present invention, based on the above-described technical solution, possesses the beneficial effects of the aforementioned air conditioner due to the adoption of the control method described above. Compared with the air conditioner before the improvement, the air conditioner of the present invention has more precise control over temperature-reaching start-stop, fewer compressor start-stop cycles, shorter temperature-reaching shutdown time, and a better user experience.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the indoor unit of the air conditioner of the present invention.

[0035] like Figure 1 As shown, the air conditioner of the present invention includes an indoor unit 1 and a temperature detection component 11 disposed on the indoor unit 1. The temperature detection component 11 is used to detect the indoor ambient temperature where the indoor unit 1 is located.

[0036] It should be noted that, in practical applications, those skilled in the art can configure the temperature detection component 11 as a temperature sensor, or as a thermometer, or as any other possible form, etc. Such adjustments and changes to the specific configuration of the temperature detection component 11 do not deviate from the protection scope of this invention.

[0037] Preferably, the temperature detection component 11 is configured as a temperature sensor.

[0038] It should be noted that, in practical applications, those skilled in the art can place the temperature detection component 11 on the housing of the indoor unit 1, or place the temperature detection component 11 at the air outlet of the indoor unit 1, etc. Such adjustments and changes to the specific placement of the temperature detection component 11 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0039] Preferably, such as Figure 1 As shown, the temperature detection component 11 is installed at the air outlet 12 of the indoor unit 1.

[0040] It should be noted that the air conditioner of the present invention has at least a cooling mode. For example, the air conditioner of the present invention may only have a cooling mode, or it may have both a cooling mode and a heating mode, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0041] It should also be noted that in practical applications, the air conditioner of the present invention can be a wall-mounted air conditioner, or a floor-standing air conditioner, or a window air conditioner, etc. Such adjustments and changes to the specific configuration type of the air conditioner do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0042] For example, the air conditioner of the present invention is a window air conditioner.

[0043] Continue reading Figure 2 , Figure 2 This is a flowchart of the control method for the air conditioner of the present invention.

[0044] like Figure 2 As shown, when the air conditioner is in cooling mode, the control method of the present invention includes the following steps:

[0045] S100: Obtain the user-defined preset temperature T0;

[0046] S200: Acquire the indoor ambient temperature T1 detected by the temperature detection component 11;

[0047] S300: Selectively adjusts the operating status of the air conditioner's compressor and indoor fan based on the preset temperature T0 and the indoor ambient temperature T1.

[0048] With this setting, when the air conditioner is in cooling mode, it acquires the indoor ambient temperature and the user-set preset temperature, and selectively adjusts the operating status of the air conditioner's compressor and indoor fan based on these conditions. This enables individual control of the compressor and indoor fan, and allows for flexible adjustment of the indoor ambient temperature through their operating status. Consequently, it facilitates precise control of the air conditioner to stop when the desired temperature is reached, thus improving the user experience.

[0049] It should be noted that the indoor ambient temperature T1 is obtained by detecting the temperature data through the temperature detection component 11.

[0050] It should also be noted that, in practical applications, those skilled in the art can obtain the indoor ambient temperature in real time, or they can obtain the indoor ambient temperature at set intervals, etc. Such adjustments and changes to the specific method of obtaining the indoor ambient temperature do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0051] Preferably, the indoor ambient temperature is acquired at set intervals.

[0052] It should be noted that, in practical applications, those skilled in the art can directly use the temperature data obtained by the temperature detection component 11 as the indoor ambient temperature, or they can first obtain multiple temperature data and then calculate the average of the multiple temperature data as the indoor ambient temperature, etc. Such adjustments and changes to the specific method of obtaining the indoor ambient temperature do not deviate from the principle and scope of the present invention and should all be included within the protection scope of the present invention.

[0053] Preferably, multiple temperature data points are first acquired, and then the average of the acquired multiple temperature data points is calculated as the indoor ambient temperature.

[0054] This setting improves the accuracy of the obtained indoor ambient temperature, thereby enhancing the precision of the air conditioner's temperature-controlled start-stop function and further improving the user experience.

[0055] It should be noted that, in practical applications, those skilled in the art can obtain the user-set preset temperature by the temperature data input by the user on the remote control that is connected to the air conditioner, or by the temperature data input by the user on the button on the air conditioner, or by the temperature data input by the user on the mobile device that is connected to the air conditioner, and so on. Such adjustments and changes to the specific method of obtaining the preset temperature do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0056] Preferably, the preset temperature set by the user is obtained by inputting temperature data on a remote control that is connected to the air conditioner.

[0057] It should be noted that, in practical applications, those skilled in the art can directly compare the preset temperature with the indoor ambient temperature, and selectively adjust the operating status of the air conditioner's compressor and indoor fan based on the comparison result. Alternatively, they can first calculate the difference between the preset temperature and the indoor ambient temperature, and then compare this difference with a first preset value and a second preset value, and selectively adjust the operating status of the air conditioner's compressor and indoor fan based on the comparison result. Or, they can first calculate the ratio of the preset temperature to the indoor ambient temperature, and then compare this ratio with a first preset value and a second preset value, and selectively adjust the operating status of the air conditioner's compressor and indoor fan based on the comparison result, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention.

[0058] The following describes in detail, with reference to two embodiments, specific implementations of selectively adjusting the compressor and indoor fan of an air conditioner based on the indoor ambient temperature and preset temperature.

[0059] Example 1:

[0060] Preferably, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan according to the preset temperature T0 and the indoor ambient temperature T1" specifically includes:

[0061] Compare the indoor ambient temperature T1 with the preset temperature T0;

[0062] Based on the comparison results, the operating status of the air conditioner's compressor and indoor fan can be selectively adjusted.

[0063] This setting allows for direct comparison between the indoor ambient temperature T1 and the preset temperature T0 to determine whether the indoor ambient temperature is lower than the preset temperature. If the indoor ambient temperature T1 is lower than the preset temperature T0, the air conditioner compressor stops running while the indoor fan continues to run, allowing the indoor fan to continue blowing the cooling energy from the indoor heat exchanger into the room, thus facilitating the reduction of the indoor ambient temperature to the preset temperature. If the indoor ambient temperature T1 is higher than or equal to the preset temperature T0, it indicates that the indoor ambient temperature has not yet reached the preset temperature, and the air conditioner compressor and indoor fan continue to run, thereby continuing to cool the indoor ambient temperature and helping to quickly reach the desired temperature.

[0064] Preferably, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison results" specifically includes:

[0065] If the indoor ambient temperature T1 is lower than the preset temperature T0, the air conditioner compressor will stop running while the indoor fan continues to run.

[0066] With this setting, when the indoor ambient temperature T1 is less than the preset temperature T0, it means that the indoor ambient temperature is lower than the preset temperature. By turning off the compressor, it can prevent the refrigerant from continuing to circulate and causing the indoor ambient temperature to drop further significantly. The indoor fan can continue to run, which can continue to blow the residual cold energy on the indoor heat exchanger into the room, thereby further reducing the indoor ambient temperature and making full use of the residual cold energy on the indoor heat exchanger.

[0067] Preferably, the step of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison results" specifically includes:

[0068] If the indoor ambient temperature T1 is greater than or equal to the preset temperature T0, the air conditioner compressor will continue to run, and the indoor fan will continue to run.

[0069] With this setting, if the indoor ambient temperature T1 is greater than or equal to the preset temperature T0, it means that the indoor ambient temperature is still higher than the preset temperature. By continuing to run the compressor and indoor fan, the indoor environment can continue to be cooled, thus making it easier to quickly reach the preset temperature and shorten the time to reach the desired temperature.

[0070] Example 2:

[0071] See next Figure 3 , Figure 3 This is a flowchart of an embodiment of the control method of the present invention.

[0072] Preferably, such as Figure 3As shown, the steps of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan according to the preset temperature T0 and the indoor ambient temperature T1" specifically include:

[0073] S310: Calculate the difference Δ = T0 - T1;

[0074] S320: Compare the difference Δ with the first preset value A1 and the second preset value A2;

[0075] S330: Based on the comparison results, selectively adjust the operating status of the air conditioner's compressor and indoor fan.

[0076] Where A1>A2≥0.

[0077] Compared to directly comparing the indoor ambient temperature with the preset temperature and selectively adjusting the operation of the air conditioner's compressor and indoor fan based on the comparison result, this method, which first calculates the difference between the preset temperature and the indoor ambient temperature, then compares this difference with a first preset value and a second preset value, and selectively adjusts the operation of the air conditioner's compressor and indoor fan based on the comparison result, can, on the one hand, avoid misjudgments caused by the detection error of the temperature detection component 11, thereby improving the accuracy of the air conditioner's temperature-reaching start-up and shutdown; on the other hand, it can avoid frequent adjustments of the compressor and indoor fan, while shortening the air conditioner's temperature-reaching control time, thus enabling the indoor ambient temperature to reach the user-set preset temperature as quickly as possible, further enhancing the user experience.

[0078] Preferably, such as Figure 3 As shown, the steps of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison results" specifically include:

[0079] S331: If △>A1, then the air conditioner compressor will stop running, and the indoor fan will also stop running.

[0080] With this setting, when △>A1, it indicates that the indoor ambient temperature is lower than the preset temperature, and the difference between the indoor ambient temperature and the preset temperature is relatively large. This means that the indoor ambient temperature is relatively low. By promptly shutting down the compressor, the refrigerant can be prevented from continuing to circulate and causing the indoor temperature to drop further. By promptly shutting down the indoor fan, the indoor fan can be prevented from blowing the cold air from the indoor heat exchanger into the room, thereby preventing the indoor ambient temperature from dropping further and improving the user experience.

[0081] Preferably, such as Figure 3 As shown, the steps of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison results" specifically include:

[0082] S332: If A2≤△≤A1, then the air conditioner compressor stops running, while the indoor fan continues to run.

[0083] With this setting, when A2≤△≤A1, it indicates that the indoor ambient temperature is lower than the preset temperature, and the difference between the preset temperature and the indoor ambient temperature is between the first preset value A1 and the second preset value A2. In this case, the compressor stops running while the indoor fan continues to run. On the one hand, this avoids the refrigerant from continuing to circulate and causing the indoor ambient temperature to drop further significantly. On the other hand, by keeping the indoor fan running, the residual cold energy on the indoor heat exchanger can continue to be blown into the room. This not only makes full use of the residual cold energy on the indoor heat exchanger, but also further reduces the indoor ambient temperature so that the actual indoor ambient temperature reaches the preset temperature. This eliminates the influence of the low-temperature radiation from the indoor heat exchanger on the temperature detection component 11, which causes the detected indoor ambient temperature to deviate. This helps to make the actual indoor ambient temperature reach the preset temperature, making the indoor ambient temperature more comfortable and further improving the user experience.

[0084] Preferably, such as Figure 3 As shown, the steps of "selectively adjusting the operating status of the air conditioner's compressor and indoor fan based on the comparison results" specifically include:

[0085] S333: If △ < A2, then the air conditioner compressor and the indoor fan will continue to run.

[0086] With this setting, when △ < A2, it indicates that the indoor ambient temperature is lower than the preset temperature, and the difference between the preset temperature and the indoor ambient temperature is relatively small, meaning the indoor ambient temperature is close to the preset temperature. Moreover, due to the influence of low-temperature radiation from the indoor heat exchanger, the temperature detection component 11 detects an excessively low indoor ambient temperature, resulting in the actual indoor temperature not yet reaching the preset temperature. If the compressor and indoor fan are turned off at this time, the indoor environment cannot be further cooled, causing the indoor ambient temperature to fail to meet the user's needs. This leads to frequent compressor start-stop and long temperature control time. Therefore, when △ < A2, allowing the air conditioner's compressor and indoor fan to continue running can further cool the indoor environment, thereby reducing the number of compressor start-stop cycles, shortening the temperature control time, and further improving the user experience.

[0087] It should be noted that in practical applications, those skilled in the art can determine the specific values ​​of the first preset value A1 and the second preset value A2 based on experience, or they can determine the specific values ​​of the first preset value A1 and the second preset value A2 based on experiments, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0088] Preferably, the specific values ​​of the first preset value A1 and the second preset value A2 are determined based on experience.

[0089] For example, the first preset value A1 is 2℃ and the second preset value A2 is 1℃.

[0090] The following describes in detail specific implementation examples of adjusting the compressor and indoor fan according to the indoor ambient temperature and preset temperature, using the following scenarios as examples.

[0091] Set the preset temperatures as follows: T0 = 20℃, A1 = 2℃, A2 = 1℃.

[0092] Scenario 1:

[0093] If the detected indoor ambient temperature T1 = 17.5℃, then △ = T0 - T1 = (20 - 17.5)℃ = 2.5℃, △ > A1, so the air conditioner compressor will stop running and the indoor fan will stop running.

[0094] Scenario 2:

[0095] If the detected indoor ambient temperature T1 = 19.5℃, then Δ = T0 - T1 = (20 - 19.5)℃ = 0.5℃, Δ < A2, so the air conditioner compressor will continue to run and the indoor fan will continue to run.

[0096] Scenario 3:

[0097] If the detected indoor ambient temperature T1 = 18.5℃, then △ = T0 - T1 = (20 - 18.5)℃ = 1.5℃, and A2 < △ < A1, then the air conditioner compressor will stop running while the indoor fan will continue to run.

[0098] Scenario 4:

[0099] If the detected indoor ambient temperature T1 = 18℃, then △ = T0 - T1 = (20 - 18)℃ = 2℃, △ = A1, which will cause the air conditioner compressor to stop running while the indoor fan continues to run.

[0100] Scenario 5:

[0101] If the detected indoor ambient temperature T1 = 19℃, then Δ = T0 - T1 = (20 - 19)℃ = 1℃, Δ = A2, which causes the air conditioner compressor to stop running while the indoor fan continues to run.

[0102] It should be noted that, in practical applications, those skilled in the art can, after the compressor stops running, allow the indoor fan to continue running for a preset time before stopping; or, after the compressor stops running, allow the indoor fan to continue running for a preset time and then obtain the current indoor ambient temperature again, selectively adjusting the operating status of the compressor and the indoor fan based on the current indoor ambient temperature and the preset temperature; or, while the indoor fan continues running after the compressor stops running, continuously monitor the current indoor ambient temperature and selectively adjust the operating status of the compressor and the indoor fan based on the current indoor ambient temperature and the preset temperature, etc. Such flexible adjustments and changes do not deviate from the principles and scope of this invention and should all be included within the protection scope of this invention.

[0103] Preferably, after the compressor stops running, the control method of the present invention further includes:

[0104] Obtain the operating time of the indoor fan after the compressor stops running;

[0105] When the running time reaches the preset time, the current indoor ambient temperature T2 detected by the temperature detection component 11 is obtained;

[0106] Based on the current ambient temperature T2 and the preset temperature T0, the operating status of the compressor and indoor fan is selectively adjusted.

[0107] With this setup, after the compressor stops running, the indoor fan blows away the residual cold air on the outdoor heat exchanger before the temperature detection component 11 detects the current indoor ambient temperature. This eliminates the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component 11, making the detected value closer to the actual indoor ambient temperature. By selectively adjusting the operating status of the compressor and indoor fan based on the detected current ambient temperature and the preset temperature, the indoor ambient temperature can be made closer to the user's preset temperature, resulting in a more comfortable indoor environment and further improving the user experience.

[0108] It should be noted that, in practical applications, those skilled in the art can directly obtain the value of the temperature detection component 11 as the current ambient temperature, or they can first obtain multiple detection data, and then calculate the average value of the multiple temperature data as the current ambient temperature, etc. Such adjustments and changes to the specific method of obtaining the current ambient temperature do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0109] Preferably, multiple detection data from the temperature detection component 11 are first acquired, and the average value of the multiple detection data is calculated as the current ambient temperature.

[0110] With this setting, compared to directly obtaining the detection data from the temperature detection component 11 as the current ambient temperature, calculating the average of multiple detection data as the current ambient temperature can more accurately obtain the specific value of the current ambient temperature. This allows for more precise control of the air conditioner's start-stop function when it reaches the set temperature, while also providing users with a more comfortable indoor environment and further enhancing the user experience.

[0111] It should be noted that in practical applications, those skilled in the art can set the specific value of the preset duration based on experience, or they can set the specific value of the preset duration based on experiments, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0112] Preferably, the specific value of the preset duration is set based on experience.

[0113] For example, the preset duration is 30 seconds.

[0114] Preferably, the step of "selectively adjusting the operating status of the compressor and the indoor fan according to the current ambient temperature T2 and the preset temperature T0" specifically includes:

[0115] Based on the current ambient temperature T2 and the preset temperature T0, determine whether the current ambient temperature is greater than the preset temperature;

[0116] Based on the assessment results, the operating status of the compressor and indoor fan are selectively adjusted.

[0117] This setup allows for more convenient adjustment of the operating status of the compressor and indoor fan.

[0118] It should be noted that in practical applications, it is not limited to determining whether the current ambient temperature is lower than the preset temperature based on the current ambient temperature T2 and the preset temperature T0, and selectively adjusting the operating status of the compressor and indoor fan based on the determination result. For example, the current ambient temperature T2 and the preset temperature T0 can be directly compared, and the operating status of the compressor and indoor fan can be selectively adjusted based on the comparison result, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0119] Preferably, based on the current ambient temperature and the preset temperature, it is determined whether the current ambient temperature is greater than the preset temperature, and based on the determination result, the operating status of the compressor and the indoor fan is selectively adjusted.

[0120] Preferably, the step of "selectively adjusting the operating status of the compressor and the indoor fan according to the judgment result" specifically includes:

[0121] If the judgment result is "no", then the compressor will remain off and the indoor fan will stop running.

[0122] With this setting, after the compressor stops running and the indoor fan has been running continuously for a preset time, the indoor fan blows away the cold air from the indoor heat exchanger, eliminating the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component 11. The current indoor ambient temperature is then detected again, and it is closer to the actual indoor ambient temperature. If the judgment result is "no", it means that the current indoor ambient temperature is less than or equal to the preset temperature, which means that the indoor ambient temperature has reached the preset temperature. The compressor is kept off and the indoor fan stops running, which can realize the air conditioner's temperature-reaching shutdown, so that the indoor ambient temperature reaches the user's preset temperature, providing the user with a more comfortable environment and further improving the user experience.

[0123] Preferably, the step of "selectively adjusting the operating status of the compressor and the indoor fan according to the judgment result" specifically includes:

[0124] If the judgment result is "yes", then start the compressor and keep the indoor fan running.

[0125] With this setting, after the compressor stops running and the indoor fan continues to run for a preset time, the indoor fan blows away the cold air from the indoor heat exchanger, eliminating the influence of low-temperature radiation from the indoor heat exchanger on the temperature detection component 11. The current indoor ambient temperature is then detected again and is closer to the actual indoor ambient temperature. If the judgment result is "yes", it means that the current ambient temperature is still higher than the preset temperature, which means that the indoor ambient temperature has not yet dropped to the preset temperature. The compressor needs to be restarted and the indoor fan needs to continue running to continue cooling the indoor environment so that the indoor ambient temperature reaches the preset temperature.

[0126] The following describes in detail specific implementation examples of adjusting the compressor and indoor fan according to the current ambient temperature and preset temperature, using the following scenarios as examples.

[0127] Set the preset temperature T0 = 20℃ and the preset duration to 30s.

[0128] Scenario 1:

[0129] After the compressor stops running, if the indoor fan has been running for 30 seconds since the compressor stopped running, and the detected current ambient temperature T2 = 21℃, then the current ambient temperature is higher than the preset temperature, the air conditioner compressor will be started and the indoor fan will continue to run.

[0130] Scenario 2:

[0131] After the compressor stops running, if the indoor fan has been running for 30 seconds since the compressor stopped running, and the detected indoor ambient temperature T1 = 20℃, then the current ambient temperature is equal to the preset temperature. In this case, the compressor will remain off and the indoor fan will stop running.

[0132] Scenario 3:

[0133] After the compressor stops running, if the indoor fan has been running for 30 seconds since the compressor stopped running, and the detected indoor ambient temperature T1 = 19.5℃, then the current ambient temperature is lower than the preset temperature, and the air conditioner compressor and indoor fan will stop running.

[0134] Furthermore, the present invention also provides an air conditioner including a controller configured to perform the control method for an air conditioner described above.

[0135] It should be noted that, in practical applications, those skilled in the art can configure the controller to communicate with the temperature detection component 11 in order to achieve intelligent acquisition of indoor ambient temperature and current ambient temperature.

[0136] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
